PROPOSED ARRANGEMENT—YOUR VOTE IS VERY IMPORTANT

Dear Stockholders,

I am pleased to inform you that VAALCO Energy, Inc., a Delaware corporation (“VAALCO”), VAALCO Energy Canada ULC, an Alberta unlimited liability company and an indirect wholly-owned subsidiary of VAALCO (“AcquireCo”), and TransGlobe Energy Corporation, an Alberta corporation (“TransGlobe”), have agreed to a strategic business combination transaction whereby AcquireCo will acquire all of the issued and outstanding TransGlobe common shares pursuant to a plan of arrangement (as defined below) (the “arrangement”) with TransGlobe becoming a direct wholly-owned subsidiary of AcquireCo and an indirect wholly-owned subsidiary of VAALCO. Upon completion of the arrangement, TransGlobe shareholders will receive 0.6727 of a share of VAALCO common stock, par value $0.10 per share (“VAALCO common stock”) for each TransGlobe common share (the “consideration shares”), subject to adjustment, pursuant to the terms of an arrangement agreement entered into by VAALCO, AcquireCo and TransGlobe on July 13, 2022 (as may be amended from time to time, the “arrangement agreement”), in a transaction valued at approximately $307 million as of the date the arrangement was publicly announced.

The arrangement will be implemented by way of a plan of arrangement (the “plan of arrangement”) in accordance with the Business Corporations Act (Alberta) (the “ABCA”) and is subject to approval by the Court of Queen’s Bench of Alberta (the “Court”), VAALCO stockholders and TransGlobe shareholders. Upon completion of the arrangement, it is expected that VAALCO stockholders will own approximately 54.5% and TransGlobe shareholders will own approximately 45.5% of the combined company calculated based on VAALCO’s vested and outstanding shares and TransGlobe’s outstanding shares, each as of the date of the arrangement agreement.

The VAALCO board of directors believes that the proposed arrangement will create a world-class, African-focused exploration and development company supporting a host of benefits to the combined company’s stockholders and other stakeholders. After the arrangement closes, which is expected in the second half of 2022, VAALCO management believes that:

•	the arrangement will bring together two complementary businesses, creating an operated, full-cycle portfolio of strong assets under a production and development-oriented business model with:

○	assets located in prolific and established basins in Egypt, Gabon, Equatorial Guinea and Canada;

○	pro forma proved reserves of 32.4 million barrels of oil equivalent (83.2% oil), a 56.3% increase on a per share basis, calculated on the basis of VAALCO’s vested and outstanding shares and TransGlobe’s outstanding shares, each as of the date of the arrangement agreement;

○

VAALCO management estimated combined 2022 production guidance range of 17,700 to 19,000 barrels of oil equivalent per day, and combined 2023 preliminary outlook production range of 17,500 to 21,500 barrels of oil equivalent per day, a 15% increase on a per share basis, calculated on the basis of VAALCO’s vested and outstanding shares and TransGlobe’s outstanding shares, each as of the date of the arrangement agreement;

○	a combination of two highly capable subsurface/technical, operational and business development teams enabling the pooling of operational best practices, skills and technology across the combined portfolio; and

○	a highly experienced management team with a strong track record of value creation in the combined company’s areas of operation;

TABLE OF CONTENTS

•

the combined company will have a larger and more diversified reserves and production base, enhancing risk management, increasing portfolio optionality to high-grade and the ability to sequence investment projects strategically, as well as increasing access to a broader set of capital sources relative to each company on a standalone basis;

•

the combined company will be in a pro forma net cash position of $97.9 million in combined cash and cash equivalents as of June 30, 2022 (prior to the receipt of $70.3 million in July and August 2022 from VAALCO’s May and June 2022 liftings), and $3.1 million in long-term debt, in each case on a pro forma combined basis, and the combined company will have access to additional liquidity under VAALCO’s existing facility agreement ($50.0 million undrawn as of June 30, 2022) and TransGlobe’s ATB Facility (as defined below) ($17.4 million (C$22.5 million) of which $3.1 million (C$4.0 million) was drawn as of June 30, 2022), which provides the combined company with the financial flexibility to invest in projects with attractive returns through continued disciplined capital allocation in the future;

•

the combined company will reinforce VAALCO’s and TransGlobe’s existing commitments to financial discipline and stockholder returns, with (i) a target annualized dividend of $28 million, an annualized target of approximately $0.25 per share (calculated based on VAALCO’s vested and outstanding shares and TransGlobe’s outstanding shares, each as of the date of the arrangement agreement), subject to board approval, and (ii) a board approved share repurchase plan of up to $30 million, or approximately $0.27 per share equivalent (calculated based on VAALCO’s vested and outstanding shares and TransGlobe’s outstanding shares, each as of the date of the arrangement agreement), subject to completion of the arrangement, and with a focus on further enhancing stockholder distributions through returning excess cash via share buybacks and/or dividends;

•

the combined company will have an attractive inventory of organic growth projects across the portfolio in all regions, and will be more favorably positioned to self-fund, optimize and generate value from these projects on account of the combined company’s superior operational and technical capabilities and financial resources, relative to each of VAALCO and TransGlobe on an individual basis;

•

with increased scale and broader geographical operations, the combined company will be well positioned to benefit from additional targeted inorganic growth in Africa, with reference to strict strategic, financial and operational criteria, that would otherwise not have been available to VAALCO on a standalone basis; and

•	stockholders in the combined company will benefit from a more liquid investment, with an increased number of shares traded on the New York Stock Exchange and London Stock Exchange, a combined stockholder profile and increased visibility in the public capital markets.

We are sending you the accompanying proxy statement to cordially invite you to attend a special meeting of the stockholders of VAALCO (the “special meeting”), which will be held entirely online at the following website: https://www.virtualshareholdermeeting.com/EGY2022SM at 11:00 AM, Eastern Time, on September 29, 2022, or such other date, time and place to which the special meeting may be adjourned or postponed, for the purpose of considering and voting upon the following proposals in connection with the arrangement:

(a)	Proposal No. 1 – The Amendment Proposal – to approve an amendment to the VAALCO Certificate of Incorporation to increase the authorized shares of VAALCO common stock from 100,000,000 shares to 160,000,000 shares (the “amendment proposal”); and

(b)	Proposal No. 2 – The Share Issuance Proposal – to approve the issuance of shares of VAALCO common stock to TransGlobe shareholders in connection with the arrangement agreement (the “share issuance proposal”).

After careful consideration, the VAALCO board of directors has unanimously determined that it is advisable and in the best interests of VAALCO and its stockholders to consummate the arrangement with TransGlobe as contemplated by the arrangement agreement, and unanimously recommends that you vote “FOR” each of the amendment proposal and the share issuance proposal.

The accompanying proxy statement provides you with information about the arrangement and the special meeting of VAALCO stockholders. VAALCO encourages you to read the proxy statement carefully and in its entirety, including the arrangement agreement, which is attached thereto as Annex A. Before deciding how to vote, you

TABLE OF CONTENTS

should consider the risk factors discussed in the “Risk Factors” section of the proxy statement. You may also obtain more information about VAALCO and TransGlobe from the documents each of them has filed with the Securities and Exchange Commission (the “SEC”) as described under the “Where You Can Find More Information” section of the proxy statement.

YOUR VOTE IS VERY IMPORTANT, NO MATTER HOW MANY SHARES YOU OWN.

The arrangement cannot be completed unless both the amendment proposal and the share issuance proposal are approved. Approval of the amendment proposal requires the affirmative vote of the holders of a majority of the outstanding shares of VAALCO common stock entitled to vote at the special meeting and therefore, an abstention from voting on the amendment proposal will have the same effect as voting against the amendment proposal. Approval of the share issuance proposal requires the affirmative vote of the holders of a majority of the shares of VAALCO common stock who, being present in person (online) or voting by proxy and entitled to vote at the special meeting, cast votes affirmatively or negatively on the share issuance proposal. An abstention from voting on the share issuance proposal will have no effect on the outcome of the vote on the share issuance proposal. Abstentions are counted for purposes of determining whether a quorum is present at the special meeting. Banks, brokers and other nominees that hold their customers’ shares in street name may not vote their customers’ shares on “non-routine” matters without instructions from their customers. As each of the amendment proposal and the share issuance proposal to be voted upon at the special meeting is considered “non-routine,” such organizations do not have discretion to vote on any proposal for which they do not receive instructions from their customers (this is referred to in this context as a “broker non-vote”). As a result, since there are no matters in which a broker non-vote may be counted, if you fail to provide your broker, bank or other nominee with any instructions regarding how to vote your shares, your shares will not be considered present at the special meeting, will not be counted for purposes of determining the presence of a quorum and will not be voted on either of the amendment proposal or the share issuance proposal.

Whether or not you plan to attend the special meeting in person (online), you are requested to promptly vote your shares by completing, signing and dating the enclosed proxy card or voting instruction form and returning it in the postage-paid envelope provided, or by voting over the telephone or via the internet as instructed in these materials. If you sign, date and mail your proxy card without indicating how you wish to vote, your vote will be counted as a vote “FOR” each of the amendment proposal and the share issuance proposal described above. If your shares are held in the name of a broker, bank or other nominee, please follow the instructions provided by that institution to vote your shares.

I strongly support the proposed arrangement of VAALCO with TransGlobe and join with our board of directors in unanimously recommending that you vote “FOR” each of the amendment proposal and the share issuance proposal described in this proxy statement.

Thank you for your continued support of VAALCO.

			By Order of the Board of Directors,

			Andrew L. Fawthrop
			Chairman of the Board of Directors

NEITHER THE SEC NOR ANY STATE SECURITIES COMMISSION HAS APPROVED OR DISAPPROVED THE ARRANGEMENT, PASSED UPON THE MERITS OR FAIRNESS OF THE ARRANGEMENT AGREEMENT OR THE TRANSACTIONS CONTEMPLATED IN THE ARRANGEMENT AGREEMENT, INCLUDING THE ARRANGEMENT, OR PASSED UPON THE ADEQUACY OR ACCURACY OF THE INFORMATION IN THIS DOCUMENT. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.

The accompanying proxy statement is dated August 29, 2022 and, together with the enclosed form of proxy card, is first being mailed or otherwise distributed to stockholders of VAALCO on or about August 30, 2022.

The words “anticipate,” “believe,” “estimate,” “expect,” “intend,” “forecast,” “outlook,” “aim,” “target,” “will,” “could,” “should,” “may,” “likely,” “plan,” “probably” or similar words may identify forward-looking statements, but the absence of these words does not mean that a statement is not forward-looking. Forward-looking statements in this proxy statement may include, but are not limited to, statements relating to:

(i)	the proposed arrangement and its expected terms, timing and closing, including receipt of required approvals, if any, satisfaction of other customary closing conditions and expected changes and appointments to the executive team and board of directors;

(ii)	estimates of pro forma reserves and future drilling, production and sales of crude oil and natural gas;

(iii)

estimates of future cost reductions, synergies, including pre-tax synergies, savings and efficiencies;

(iv)	expectations regarding VAALCO’s ability to effectively integrate assets and properties it may acquire as a result of the proposed arrangement into VAALCO’s operations;

(v)	expectations regarding future exploration and the development, growth and potential of VAALCO’s and TransGlobe’s operations, project pipeline and investments, and schedule and anticipated benefits to be derived therefrom;

(vi)	expectations regarding future investments or divestitures;

(vii)

expectations of future dividends and returns to stockholders including share buybacks;

(viii)

expectations of future balance sheet strength including pro forma financial metrics;

(ix)	expectations of future equity and enterprise value;

(x)	expectations regarding the listing of VAALCO common stock on the NYSE and LSE; and delisting of TransGlobe common shares from Nasdaq, TSX and AIM;

(xi)	expectations regarding the percentage share of the combined company that are expected to be owned by existing VAALCO stockholders and TransGlobe shareholders;

(xii)

expectations of future plans, priorities, focus and benefits of the proposed arrangement and the combined company;

(xiii)

the combined company’s environmental, social and governance related focus and commitments, and the anticipated benefits to be derived therefrom;

(xiv)

terms of hedging contracts; and

(xv)	expectations relating to resource potential and the potential to add reserves.

Additionally, statements relating to “reserves” are deemed to be forward-looking statements, as they involve the implied assessment, based on certain estimates and assumptions, that the reserves described exist in the quantities predicted or estimated and can be profitably produced in the future. Forward-looking statements regarding the percentage share of the combined company that are expected to be owned by existing VAALCO stockholders and TransGlobe shareholders have been calculated based on VAALCO’s vested and outstanding shares and TransGlobe’s outstanding shares, each as of the date of the arrangement agreement.

Dividends beyond the third quarter of 2022 have not yet been approved or declared by the VAALCO board of directors. Management’s expectations with respect to future dividends, annualized dividends or other returns to stockholders, including share buybacks, are forward-looking statements. Investors are cautioned that such statements with respect to future dividends and share buybacks are non-binding. The declaration and payment of future dividends or the decision as to the terms of any share buybacks remain at the discretion of the VAALCO board of

TABLE OF CONTENTS

directors and will be determined based on VAALCO’s financial results, balance sheet strength, cash and liquidity requirements, future prospects, crude oil and natural gas prices, and other factors deemed relevant by the VAALCO board of directors. The VAALCO board of directors reserves all powers related to the declaration and payment of dividends. Consequently, in determining the dividend to be declared and paid on VAALCO common stock, the VAALCO board of directors may revise or terminate the payment level at any time without prior notice.

Projections and Illustrative Scenarios (as defined below) as used in this proxy statement are considered “forward-looking statements.” Forward-looking statements representing post-closing expectations are inherently uncertain. Estimates such as expected accretion, expected production, expected capital expenditures, expected operating expenditures, earnings before interest, taxes, depreciation and amortization, adjusted to reflect the impact of hedging but before non-cash or unusual items, such as depletion and non-cash income and expenses (“Adjusted EBITDA”), financial flexibility and balance sheet strength are preliminary in nature. There can be no assurance that the proposed arrangement will close or that the forward-looking statements will prove to be accurate. You should not place undue reliance on these estimates in deciding how your vote should be cast or in voting your shares on the amendment proposal and the share issuance proposal set forth in this proxy statement.

Such forward-looking statements are subject to risks, uncertainties and other factors, which could cause actual results to differ materially from future results expressed, projected or implied by the forward-looking statements. These risks and uncertainties include, but are not limited to:

•	the ability to obtain stockholder, shareholder, court and regulatory approvals (if any) in connection with the proposed arrangement;

•	the ability to complete the proposed arrangement on the anticipated terms and timetable;

•	the possibility that various closing conditions for the arrangement may not be satisfied or waived;

•	risks relating to any unforeseen liabilities of VAALCO and/or TransGlobe;

•	the tax treatment of the proposed arrangement in the United States and Canada;

•	declines in oil or natural gas prices;

•	the level of success in exploration, development and production activities;

•	adverse weather conditions that may negatively impact development or production activities;

•	the timing and costs of exploration and development expenditures;

•	inaccuracies of reserve estimates or assumptions underlying them;

•	revisions to reserve estimates as a result of changes in commodity prices;

•	impacts to financial statements as a result of impairment write-downs;

•	the ability to generate cash flows that, along with cash on hand, will be sufficient to support operations, stockholder returns and cash requirements;

•	the ability to attract capital or obtain debt financing arrangements;

•	currency exchange rates and regulations;

•	actions by joint venture co-owners;

•	hedging decisions, including whether or not to enter into derivative financial instruments;

•	international, federal, state and provincial initiatives relating to the regulation of hydraulic fracturing;

•	failure of assets to yield oil or gas in commercially viable quantities;

•	uninsured or underinsured losses resulting from oil and gas operations;

•	inability to access oil and gas markets due to market conditions or operational impediments;

•	the impact and costs of compliance with laws and regulations governing oil and gas operations;

•	the ability to replace oil and natural gas reserves;

TABLE OF CONTENTS

•	any loss of senior management or technical personnel;

•	competition in the oil and gas industry; and

•	the risk that the proposed arrangement may not increase VAALCO’s relevance to investors in the international exploration and production industry, increase capital market access through scale and diversification or provide liquidity benefits for stockholders.

For a more detailed discussion of such risks and other risk factors, please refer to the “Risk Factors” section of this proxy statement; VAALCO’s 2021 Annual Report on Form 10-K, filed with the SEC on March 11, 2022; VAALCO’s Quarterly Report on Form 10-Q for the quarterly period ended June, 30, 2022, filed with the SEC on August 10, 2022; TransGlobe’s 2021 Annual Report on Form 40-F, filed with the SEC on March 17, 2022; and the other documents of VAALCO and TransGlobe that are incorporated by reference into this proxy statement.

Neither VAALCO nor TransGlobe is affirming or adopting any statements or reports attributed to the other (including oil and gas reserves information) in this proxy statement or made by the other outside of this proxy statement. There may be additional risks that VAALCO does not presently know or that VAALCO currently believes are immaterial, that could also cause actual results to differ from those contained in the forward-looking statements. In addition, forward-looking statements reflect VAALCO’s expectations, plans or forecasts of future events and views as of the date of this proxy statement. Should one or more of these risks or uncertainties materialize, or should any of the assumptions prove incorrect, actual results may vary in material respects from those projected in these forward-looking statements. No obligation is being undertaken to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise, except as may be required under applicable securities laws. You should not place undue reliance on these forward-looking statements in deciding how your vote should be cast or in voting your shares on the amendment proposal and the share issuance proposal set forth in this proxy statement.

QUESTIONS AND ANSWERS ABOUT THE SPECIAL MEETING

The following questions and answers briefly address some commonly asked questions about the amendment proposal and the share issuance proposal to be presented at the special meeting. The following questions and answers do not include all the information that is important to our stockholders with respect to the arrangement. We urge our stockholders to carefully read this entire proxy statement, including its annexes and other documents incorporated by reference into this proxy statement.

Q:	Why am I receiving this proxy statement?

VAALCO has agreed to acquire TransGlobe pursuant to the terms and conditions of the arrangement agreement and the plan of arrangement that are described in this proxy statement. If completed, the arrangement will result in AcquireCo, an indirect wholly-owned subsidiary of VAALCO, acquiring all of the issued and outstanding TransGlobe common shares in exchange for newly issued shares of VAALCO common stock pursuant to the plan of arrangement. As a result, TransGlobe will become a direct wholly-owned subsidiary of AcquireCo and an indirect wholly-owned subsidiary of VAALCO. The arrangement will require shares of VAALCO common stock representing approximately 82.4% of VAALCO’s outstanding common stock to be issued to TransGlobe shareholders. Immediately after the completion of the arrangement, it is expected that VAALCO’s former stockholders will own approximately 54.5% and TransGlobe shareholders will own approximately 45.5% of the combined company. The percentages in the preceding sentence are calculated based on VAALCO’s vested and outstanding shares and TransGlobe’s outstanding shares, each as of the date of the arrangement agreement. A copy of the arrangement agreement is attached to this proxy statement as Annex A.

You are receiving this proxy statement because you have been identified as a holder of VAALCO common stock. This proxy statement is being used to solicit proxies on behalf of the VAALCO board of directors for the special meeting to obtain the required approval of VAALCO stockholders. This proxy statement contains important information about the arrangement and related transactions and the special meeting, and you should read it carefully.

In order to complete the arrangement, TransGlobe must obtain a final order from the Court approving the arrangement and all other conditions to the arrangement must be satisfied or waived. TransGlobe will hold a separate shareholder meeting to obtain the required approval of its shareholders.

Q:	What will I receive under the arrangement?

VAALCO stockholders will not receive any consideration in the arrangement. VAALCO stockholders will continue to own their existing shares of VAALCO common stock after the arrangement. Immediately after the completion of the arrangement, it is expected that VAALCO stockholders will own approximately 54.5% and TransGlobe shareholders will own approximately 45.5% of the combined company, calculated based on VAALCO’s vested and outstanding shares and TransGlobe’s outstanding shares, each as of the date of the arrangement agreement.

Q:	How do I attend the special meeting?

As a registered VAALCO stockholder, you will receive or have received a notice and access instruction form or proxy card from Broadridge Financial Solutions, Inc. (“Broadridge”), as distribution agent for VAALCO. Both forms contain instructions on how to attend the special meeting in person (online) including the URL address (https://www.virtualshareholdermeeting.com/EGY2022SM), along with your 16-digit control number. A registered VAALCO stockholder will need its 16-digit control number for access. Registered VAALCO stockholders may obtain their 16-digit control numbers by calling Broadridge at (844) 983-0876 (toll-free) or (303) 562-9303 (international toll).

If your shares of VAALCO common stock are held in “street name” by your broker, bank or other nominee, you should have received an instruction form with these proxy materials with your 16-digit control number from that organization rather than from Broadridge. If you do not have your 16-digit control number, please call your broker, bank or other nominee.

You can pre-register to attend the special meeting in person (online) starting September 29, 2022 at 10:45 AM, Eastern Time, by entering the URL address (https://www.virtualshareholdermeeting.com/EGY2022SM) into your browser, and entering your 16-digit control number, name and email address. Once you pre-register, you

TABLE OF CONTENTS

can vote or enter questions in the chat box. At the start of the special meeting, you will need to re-log in using your 16-digit control number. You will also be prompted to enter your 16-digit control number if you vote during the special meeting.

Q:	What will the VAALCO stockholders be asked to vote on at the special meeting?

A:	At the special meeting, VAALCO stockholders will be asked to consider and vote on the following proposals:

1.	Proposal No. 1 – The Amendment Proposal – to approve an amendment to the VAALCO Certificate of Incorporation to increase the authorized shares of VAALCO common stock from 100,000,000 shares to 160,000,000 shares; and

2.	Proposal No. 2 – The Share Issuance Proposal – to approve the issuance of shares of VAALCO common stock to TransGlobe shareholders in connection with the arrangement agreement.

Q:	What will the TransGlobe shareholders be asked to vote on?

TransGlobe shareholders will not be asked to vote on either of the amendment proposal or the share issuance proposal to be considered and voted upon at the special meeting. Rather, pursuant to the arrangement agreement, TransGlobe shareholders will be asked to vote on the TransGlobe resolution at TransGlobe’s shareholder meeting.

TransGlobe’s shareholder meeting will be held on September 29, 2022. Among other things, the closing of the arrangement is conditional on the approval of the TransGlobe resolution by the affirmative vote of at least two-thirds of the votes cast on the TransGlobe resolution by TransGlobe shareholders present in person or represented by proxy and entitled to vote at the TransGlobe meeting voting together as a single class.

Q:	Who is eligible to vote at the special meeting?

A:	Holders of VAALCO common stock as of the record date are eligible to vote at the special meeting.

Q:	How many votes do VAALCO stockholders have?

A:	Holders of VAALCO common stock are entitled to cast one vote on each proposal properly brought before the special meeting for each share of VAALCO common stock that such holder owned at the record date.

Q:	What constitutes a quorum for the special meeting?

The holders of a majority of the shares of VAALCO common stock issued and outstanding and entitled to vote at the special meeting must be present in person (online) or represented by proxy in order to constitute a quorum for all matters to come before the special meeting. Abstentions are counted for purposes of determining whether a quorum is present at the special meeting. Banks, brokers and other nominees that hold their customers’ shares in street name may not vote their customers’ shares on “non-routine” matters without instructions from their customers. As each of the amendment proposal and the share issuance proposal to be voted upon at the special meeting is considered “non-routine,” such organizations do not have discretion to vote on any proposal for which they do not receive instructions from their customers (this is referred to in this context as a “broker non-vote”). As a result, since there are no matters in which a broker non-vote may be counted, if you fail to provide your broker, bank or other nominee with any instructions regarding how to vote your shares, your shares will not be considered present at the special meeting, will not be counted for purposes of determining the presence of a quorum and will not be voted on either of the amendment proposal or the share issuance proposal. If you provide instructions to your broker, bank or other nominee which indicate how to vote your shares with respect to one proposal but not with respect to the other proposal, your shares will be considered present at the special meeting and be counted for purposes of determining the presence of a quorum and voted, as instructed, with respect to the appropriate proposal, but will not be voted with respect to the other proposal.

If a quorum is not present at the special meeting, VAALCO’s chair of the board of directors may adjourn the special meeting to continue to solicit proxies. Regardless of whether a quorum is present at the special meeting, VAALCO’s chair of the board or the person presiding as chairman of the special meeting may adjourn the special meeting to a later date, without notice other than announcement at the special meeting. If an adjournment

TABLE OF CONTENTS

is for more than 30 days, or if after the adjournment a new record date is fixed for the adjourned special meeting, VAALCO will provide notice of the adjourned special meeting to each VAALCO stockholder of record entitled to vote at that special meeting scheduled to a later date.

Q:	What vote by the VAALCO stockholders is required to approve the amendment proposal?

A:	Pursuant to the DGCL Section 242, approval of the amendment proposal will require the affirmative vote of the holders of a majority of the outstanding shares of VAALCO common stock entitled to vote at the special meeting.

Q:	What vote by the VAALCO stockholders is required to approve the share issuance proposal?

Pursuant to Section 312.03 of the Listed Company Manual of the NYSE and the VAALCO Bylaws, approval of the share issuance proposal will require the affirmative vote of holders of a majority of the shares of VAALCO common stock who, being present in person (online) or voting by proxy and entitled to vote at the special meeting, cast votes affirmatively or negatively on the share issuance proposal.

Q:	Why is my vote important?

In order to complete the arrangement, VAALCO stockholders must approve the amendment proposal and the share issuance proposal. An abstention from voting on the amendment proposal will have the same effect as voting against the amendment proposal. An abstention from voting on the share issuance proposal will have no effect on the outcome of the vote on the share issuance proposal. Abstentions are counted for purposes of determining whether a quorum is present at the special meeting. Banks, brokers and other nominees that hold their customers’ shares in street name may not vote their customers’ shares on “non-routine” matters without instructions from their customers. As each of the amendment proposal and the share issuance proposal to be voted upon at the special meeting is considered “non-routine,” such organizations do not have discretion to vote on any proposal with a broker non-vote. As a result, since there are no matters in which a broker non-vote may be counted, if you fail to provide your broker, bank or other nominee with any instructions regarding how to vote your shares, your shares will not be considered present at the special meeting, will not be counted for purposes of determining the presence of a quorum and will not be voted on either of the amendment proposal or the share issuance proposal.

Q:	Why am I being asked to consider and vote on the amendment proposal?

Approval of the amendment proposal is necessary for VAALCO to have enough authorized shares of VAALCO common stock to issue the consideration shares. The VAALCO Certificate of Incorporation does not currently authorize a sufficient number of shares of VAALCO common stock to satisfy the consideration shares payable under the arrangement. VAALCO is currently authorized to issue 100 million shares of VAALCO common stock. As of the date of this proxy statement, approximately 59.8 million shares of VAALCO common stock were outstanding. VAALCO must issue approximately 49.3 million shares of VAALCO common stock to complete the arrangement. Authorizing additional shares of VAALCO common stock is required to enable VAALCO to have sufficient shares of VAALCO common stock authorized for issuance in order to deliver the consideration shares payable under the arrangement. Pursuant to the DGCL and the arrangement agreement, we are required to submit the amendment proposal to VAALCO stockholders for approval.

Q:	Why am I being asked to consider and vote on the share issuance proposal?

As VAALCO common stock is listed for trading on the NYSE, issuances of shares of VAALCO common stock are subject to the NYSE Listed Company Manual. Section 312.03(c) of the NYSE Listed Company Manual requires stockholder approval prior to the issuance of common stock in any transaction if the number of shares of common stock to be issued is, or will be upon issuance, equal to or in excess of 20% of the number of shares of common stock outstanding before the issuance of the common stock. The number of shares of VAALCO common stock to be issued to TransGlobe shareholders as consideration for the arrangement will exceed 20% of the number of shares of VAALCO common stock outstanding before the issuance. Therefore, under Section 312.03(c) of the NYSE Listed Company Manual, stockholder approval of the share issuance proposal is required.

Q:	Will the newly issued shares of VAALCO common stock be traded on an exchange?

A:	It is a condition to the completion of the arrangement that the shares of VAALCO common stock to be issued to TransGlobe shareholders in exchange for their TransGlobe common shares pursuant to the arrangement be

TABLE OF CONTENTS

approved for listing on the NYSE. Accordingly, VAALCO has agreed to use commercially reasonable efforts to obtain approval of the listing of the consideration shares for trading on the NYSE. It is also a condition to the arrangement that the FCA must have acknowledged that the application for admission to trading on the Main Market has been approved by the FCA and such admission has become effective. Accordingly, VAALCO has agreed to use its commercially reasonable efforts to obtain by the effective time (i) acknowledgment from the FCA that the application for admission to trading on the Main Market has been approved; and (ii) acknowledgment from the LSE that the conditions to the consideration shares being admitted to trading on the Standard List have been satisfied. VAALCO will provide the required notice to the NYSE of the listing of the shares of VAALCO common stock to be issued in connection with the arrangement prior to the closing of the arrangement.

Q:	What are VAALCO’s reasons for proposing the arrangement and entering into the arrangement agreement?

The VAALCO board of directors concluded that the arrangement provides significant potential benefits to VAALCO, including, among other things, the diversification of the asset portfolio and revenue streams of the combined company in favorable geographies, the opportunity to participate in new and enhanced growth prospects, and that the arrangement offers benefits to VAALCO on a pro forma per share basis across key metrics including reserves and production, that outweigh the uncertainties, risks and potentially negative factors relevant to the arrangement. For a more detailed discussion of the reasoning of the VAALCO board of directors, see “The Arrangement—VAALCO’s Reasons for the Arrangement” and “The Arrangement—Recommendations of the VAALCO Board of Directors” sections of this proxy statement.

Q:	What is an arrangement?

An arrangement is a statutory procedure under Canadian corporate law that allows companies to carry out transactions upon receiving shareholder and court approval that then becomes binding on all other shareholders by operation of law. The arrangement that is being proposed by TransGlobe, a company continued into Alberta under the ABCA, will allow AcquireCo, an indirect wholly-owned subsidiary of VAALCO, to acquire all of the outstanding TransGlobe common shares pursuant to a plan of arrangement under the ABCA.

Q:	How does the VAALCO board of directors recommend that I vote?

A:	The VAALCO board of directors unanimously recommends that you vote “FOR” each of the amendment proposal and the share issuance proposal to be considered and voted upon at the special meeting.

Q:	What do I need to do now?

Please carefully read this proxy statement, its annexes and other documents incorporated by reference into this proxy statement to consider how the arrangement affects you. After reading, you should complete, sign and date your proxy card and mail it in the enclosed return envelope or submit your proxy over the telephone or over the internet as soon as possible so that your shares can be voted at the special meeting. If you sign, date and mail your proxy card without indicating how you wish to vote, your vote will be counted as a vote “FOR” each of the amendment proposal and the share issuance proposal being considered and voted upon at the special meeting. If your shares of VAALCO common stock are held in “street name” by your broker, bank or other nominee, you should have received an instruction form with these proxy materials with your 16-digit control number from that organization rather than from Broadridge. You will need your 16-digit control number in order for you to vote. If you do not have your 16-digit control number, please call your broker, bank or other nominee. Your broker, bank or other nominee will vote your shares only if you provide instructions on how you would like your shares to be voted.

If your shares of VAALCO common stock are held in “street name” by your broker, bank or other nominee, you should have received a voting instruction form with these proxy materials with your 16-digit control number from that organization rather than from Broadridge. Your broker, bank or other nominee will vote your shares only if you provide instructions to that organization on how to vote. You should provide your broker, bank or other nominee with instructions regarding how to vote your shares by following the enclosed procedures provided by that organization. Your shares will not be voted with respect to any proposal for which you fail to provide instructions, which will have (i) the same effect as a vote cast against the amendment proposal or (ii) no effect on the outcome of the vote on the share issuance proposal.

A 16-digit control number, located on your proxy card or voting instruction form, is designed to verify your identity and allow you to vote your shares of VAALCO common stock, and to confirm that your voting instructions have been properly recorded when voting over the internet or by telephone.

Q:	What does it mean if I receive more than one set of materials?

This means you own shares of VAALCO common stock that are registered under different names. For example, you may own some shares directly as a VAALCO stockholder of record and other shares through a broker, or you may own shares through more than one broker, bank or other nominee. In these situations, you will receive multiple sets of proxy materials. You must complete, sign, date and return each of the proxy cards and voting instruction forms that you receive, or vote all of your shares over the telephone or over the internet in accordance with the instructions above in order to vote all of the shares you own. Each proxy card you receive comes with its own prepaid return envelope and 16-digit control number(s). If you vote by mail, make sure you return each proxy card in the return envelope that accompanies that proxy card or voting instruction form, and if you vote by telephone or via the internet, please follow the enclosed instructions and use your 16-digit control number(s).

Q:	What happens if I sell my shares of common stock before the special meeting?

The record date for VAALCO stockholders entitled to vote at the special meeting is earlier than the date of the special meeting. If you transfer your shares of VAALCO common stock after the record date, but before the date of the special meeting, you will retain your right to vote at the special meeting unless special arrangements are made between you and the person to whom you transfer your shares. If you sold your shares after the record date you are encouraged to still vote the shares you owned on the record date.

Q:	May I vote in person (online)?

If you are a VAALCO stockholder of record, you have the right to vote in person (online) at the special meeting with respect to those shares. If you are the beneficial owner of shares of VAALCO common stock, you are invited to attend the special meeting and should have received an instruction form with these proxy materials with your 16-digit control number from your broker, bank or other nominee rather than from Broadridge. If you

TABLE OF CONTENTS

do not have your 16-digit control number, you may not be able to attend and vote your shares in person (online) at the special meeting, unless you call your broker, bank or other nominee to receive your 16-digit control number. Even if you plan to attend the special meeting, VAALCO recommends that you also submit your proxy card or voting instructions as described above under “How do I vote?” so that your vote will be counted if you later decide not to attend the special meeting.

Q:	How can I change or revoke my vote?

You have the right to revoke a proxy delivered by mail, by telephone or over the internet at any time before your proxy is voted at the special meeting by (i) voting again at a later date through any of the methods available to you, (ii) delivering written notice of revocation to VAALCO’s corporate secretary by the time the special meeting begins, or (iii) attending the special meeting and voting in person (online).

Q:	Am I entitled to appraisal rights?

A:	No. Under the DGCL, holders of shares of VAALCO common stock are not entitled to appraisal rights in connection with the arrangement or any of the matters to be acted on at the special meeting.

Q:	Is completion of the arrangement subject to any conditions?

Yes. VAALCO and TransGlobe cannot complete the arrangement unless a number of conditions are satisfied or waived, including receipt of the required approvals from the VAALCO stockholders, TransGlobe shareholders and the Court. See “The Arrangement Agreement and the Plan of Arrangement—Conditions to Completion of the Arrangement” section of this proxy statement for a more complete summary of the conditions that must be satisfied or waived prior to completion of the arrangement.

Q:	Are the amendment proposal and the share issuance proposal conditioned upon one another?

Yes. The amendment proposal and the share issuance proposal are conditioned upon each other. Adoption by our stockholders of both the amendment proposal and the share issuance proposal are conditions to the closing of the arrangement. Accordingly, if either the amendment proposal or the share issuance proposal is not approved, a condition to the closing of the arrangement will not be satisfied and the arrangement will not be completed.

Q:	What happens if the arrangement is terminated?

If the arrangement is terminated, TransGlobe will not be combined with VAALCO, and TransGlobe and VAALCO will continue to operate as separate entities as they did before. The arrangement agreement contains certain termination rights for both TransGlobe and VAALCO, including where (i) the arrangement is not consummated on or before the outside date; (ii) a law or order comes into effect prohibiting consummation of the arrangement and such law or order has become final and non-appealable; or (iii) the TransGlobe shareholder approval of the TransGlobe resolution or the VAALCO stockholder approval of the amendment proposal and the share issuance proposal is not obtained at TransGlobe’s shareholder meeting or the special meeting, respectively. Additionally, each of VAALCO and TransGlobe has a separate termination right in certain circumstances, including if (i) the board of directors of the other party changes its recommendation prior to the time that such party’s stockholder or shareholder approval, as the case may be, is obtained; (ii) the other party materially breaches its non-solicitation covenants; (iii) there is or has been a material adverse effect on the other party; or (iv) the other party breaches any representation or warranty or fails to perform any covenant or agreement that would cause certain conditions precedent to the arrangement not to be satisfied, and such conditions are incapable of being satisfied by the outside date.

The arrangement agreement further provides that, upon termination of the arrangement agreement under certain circumstances, TransGlobe will be required to pay to VAALCO a termination fee of $9.15 million in connection with such termination, or VAALCO will be required to pay to TransGlobe a termination fee of $9.15 million in connection with such termination. Under certain circumstances upon termination, the arrangement agreement also provides that TransGlobe or VAALCO will be required to reimburse the other party for out-of-pocket expenses incurred up to $2.00 million. See “The Arrangement Agreement and the Plan of Arrangement—Termination of the Arrangement Agreement” section of this proxy statement for a more complete summary of the termination provisions under the arrangement agreement.

TABLE OF CONTENTS

Q:	When does VAALCO expect the arrangement to become effective?

The arrangement is expected to close in the second half of 2022. Closing is conditional on TransGlobe shareholders approving the TransGlobe resolution, the approval of VAALCO stockholders of the amendment proposal and the share issuance proposal, and the satisfaction of other closing conditions. See “The Arrangement Agreement and the Plan of Arrangement—Conditions to Completion of the Arrangement” section of this proxy statement.

Q:	What will happen if the arrangement is completed?

If the arrangement is completed, AcquireCo will acquire all of the issued and outstanding TransGlobe common shares and TransGlobe will become a direct wholly-owned subsidiary of AcquireCo and an indirect wholly-owned subsidiary of VAALCO. VAALCO intends to have the TransGlobe common shares delisted from AIM, the TSX and Nasdaq as promptly as possible following completion of the arrangement. In addition, it is expected that VAALCO will, subject to applicable law, apply to have TransGlobe cease to be a reporting issuer in all jurisdictions in which it is a reporting issuer and thus will terminate TransGlobe’s reporting obligations in Canada and the United States following completion of the arrangement. Upon completion of the arrangement, VAALCO will become a reporting issuer in each of the provinces of Canada by virtue of the completion of the arrangement with TransGlobe. Subject to certain exceptions, VAALCO will be generally exempt from Canadian statutory financial and other continuous and timely reporting requirements, including the requirement for insiders of VAALCO to file reports with respect to trades of VAALCO securities, provided VAALCO complies with the requirements of U.S. securities laws and U.S. market requirements in respect of all financial and other continuous and timely reporting matters and VAALCO files with the relevant Canadian securities regulatory authorities copies of its documents filed with the SEC under the Exchange Act.

Q:	Who will be the directors and executive officers of the combined company following the arrangement?

VAALCO has agreed with TransGlobe that it will take all actions necessary to ensure that, as of the effective time, the VAALCO board of directors will be comprised of four members of VAALCO’s existing board of directors: Andrew L. Fawthrop, George Maxwell, Cathy Stubbs and Fabrice Nze-Bekale; and three members of TransGlobe’s existing board of directors: David Cook, Edward LaFehr and Timothy Marchant. Andrew L. Fawthrop will continue as the chairman of the VAALCO board of directors. See “The Arrangement—Board of Directors Following the Arrangement” section of this proxy statement.

VAALCO anticipates that its Chief Executive Officer and Chief Financial Officer will remain with VAALCO following the consummation of the arrangement.

VAALCO expects to exercise the rights contained in the employment agreements of each of TransGlobe’s President and Chief Executive Officer, Vice President, Finance, Chief Financial Officer and Corporate Secretary and Vice President and Chief Operating Officer that will require such officer to remain employed by the combined company for a minimum of a three-month period following the consummation of the arrangement. For additional information, see “The Arrangement—Management Following the Arrangement” section of this proxy statement.

Q:	Are there any risks I should consider in connection with the arrangement?

A:	Yes. There are a number of risk factors relating to VAALCO’s business and operations, the arrangement and the combined company’s business and operations, all of which should be carefully considered. See the “Risk Factors” section of this proxy statement.

Q:	Is this VAALCO’s annual meeting? Will I be voting on the election of directors at the special meeting?

No. This is not VAALCO’s annual meeting and you will not be asked to elect directors at the special meeting. The special meeting will take place entirely online at the following website: https://www.virtualshareholdermeeting.com/EGY2022SM, at 11:00 AM, Eastern Time, on September 29, 2022, unless adjourned or postponed to a later date.

Special Meeting of VAALCO Stockholders

The Special Meeting

The special meeting will be held entirely online at the following website: https://www.virtualshareholdermeeting.com/EGY2022SM, at 11:00 AM, Eastern Time, on September 29, 2022, or such other date, time and place to which the special meeting may be adjourned or postponed. VAALCO stockholders are being asked to consider and vote on the following proposals in connection with the arrangement:

1.	Proposal No. 1 – The Amendment Proposal – to approve an amendment to the VAALCO Certificate of Incorporation to increase the authorized shares of VAALCO common stock from 100,000,000 shares to 160,000,000 shares; and

2.	Proposal No. 2 – The Share Issuance Proposal – to approve the issuance of shares of VAALCO common stock to TransGlobe shareholders in connection with the arrangement agreement.

Record Date for the Special Meeting

You can vote at the special meeting all of the shares of VAALCO common stock you held of record as of the close of business on August 24, 2022, which is the record date for the special meeting. As of the record date, there were 59,826,544 shares of VAALCO common stock outstanding.

Recommendations of the VAALCO Board of Directors

The VAALCO board of directors unanimously recommends that you vote “FOR” each of the amendment proposal and the share issuance proposal to be considered and voted upon at the special meeting. In connection with this recommendation, the VAALCO board of directors has determined that it is advisable and in the best interests of

TABLE OF CONTENTS

VAALCO and its stockholders to amend the VAALCO Certificate of Incorporation to increase the number of authorized shares of VAALCO common stock and to issue the VAALCO common stock in connection with the arrangement. See “The Arrangement—VAALCO’s Reasons for the Arrangement” and “The Arrangement—Recommendations of the VAALCO Board of Directors” sections of this proxy statement for more information about the factors considered by the VAALCO board of directors.

Required Vote

Each share of VAALCO common stock is entitled to one vote at the special meeting. The holders of a majority of the shares of VAALCO common stock issued and outstanding and entitled to vote at the special meeting must be present in person (online) or represented by proxy in order to constitute a quorum for all matters to come before the special meeting. Abstentions are counted for purposes of determining whether a quorum is present at the special meeting. Banks, brokers and other nominees that hold their customers’ shares in street name may not vote their customers’ shares on “non-routine” matters without instructions from their customers. As each of the amendment proposal and the share issuance proposal to be voted upon at the special meeting is considered “non-routine,” such organizations do not have discretion to vote on any proposal with a broker non-vote. As a result, since there are no matters in which a broker non-vote may be counted, if you fail to provide your broker, bank or other nominee with any instructions regarding how to vote your shares, your shares will not be considered present at the special meeting, will not be counted for purposes of determining the presence of a quorum and will not be voted on either of the amendment proposal or the share issuance proposal. If you provide instructions to your broker, bank or other nominee which indicate how to vote your shares with respect to one proposal but not with respect to the other proposal, your shares will be considered present at the special meeting and will be counted for purposes of determining the presence of a quorum and voted, as instructed, with respect to the appropriate proposal, but will not be voted with respect to the other proposal.

Approval of the amendment proposal and the share issuance proposal presented at the special meeting will require the following:

•

Approval of the adoption of the amendment proposal will require the affirmative vote of the holders of a majority of the outstanding shares of VAALCO common stock entitled to vote at the special meeting. An abstention from voting on the amendment proposal will have the same effect as voting against the amendment proposal. A broker non-vote will not be voted on the amendment proposal.

•

Approval of the share issuance proposal will require the affirmative vote of the holders of a majority of the shares of VAALCO common stock who, being present in person (online) or voting by proxy and entitled to vote at the special meeting, cast votes affirmatively or negatively on the share issuance proposal. An abstention from voting on the share issuance proposal will have no effect on the outcome of the vote on the share issuance proposal. A broker non-vote will not be voted on the share issuance proposal.

Security Ownership of Certain Beneficial Owners and Management

As of the close of business on August 24, 2022, the current directors and executive officers of VAALCO were deemed to beneficially own 1,269,038 shares of VAALCO common stock, constituting, in the aggregate, 2.1% of the shares of VAALCO common stock outstanding on that date. Beneficial ownership is determined in accordance with SEC rules as described under “The Special Meeting—Security Ownership of Certain Beneficial Owners and Management” section of this proxy statement.

The Arrangement

The arrangement agreement provides that at the effective time, AcquireCo will acquire all of the issued and outstanding TransGlobe common shares with TransGlobe continuing as a direct wholly-owned subsidiary of AcquireCo and an indirect wholly-owned subsidiary of VAALCO. The arrangement will be implemented under the ABCA and requires approval of (a) at least two-thirds of the votes cast by TransGlobe shareholders who vote in person or by proxy at TransGlobe’s shareholder meeting voting together as a single class and (b) the Court. After giving effect to the arrangement, AcquireCo will own all of the outstanding TransGlobe common shares. As TransGlobe is a corporation existing under the ABCA, the acquisition is being effected through an arrangement instead of a merger.

A copy of the arrangement agreement and the plan of arrangement are attached as Annex A to this proxy statement. You are urged to read the arrangement agreement and the plan of arrangement in their entirety

TABLE OF CONTENTS

because they are the legal documents that govern the arrangement. For more information on the arrangement, the arrangement agreement and the plan of arrangement, see “The Arrangement Agreement and the Plan of Arrangement” section of this proxy statement.

Consideration Shares Received Pursuant to the Arrangement

If the arrangement is completed, each TransGlobe common share outstanding immediately prior to the effective time (excluding shares held by VAALCO, AcquireCo or any of their respective affiliates or by shareholders that validly exercise, and do not withdraw, their dissent rights) will be deemed to be transferred and assigned to AcquireCo in exchange for 0.6727 of a share of VAALCO common stock, subject to adjustment (if any) pursuant to the arrangement agreement. No fractional shares of VAALCO common stock will be issued as part of the arrangement, and TransGlobe shareholders will receive cash in lieu of any fractional shares of VAALCO common stock in accordance with the terms of the plan of arrangement. Upon completion of the arrangement, it is expected that VAALCO stockholders will own approximately 54.5%, and TransGlobe shareholders will own approximately 45.5% of the combined company, calculated based on VAALCO’s vested and outstanding shares and TransGlobe’s outstanding shares, each as of the date of the arrangement agreement.

Non-Solicitation of Alternative Transactions and Change in Recommendation

Each of TransGlobe and VAALCO has agreed not to, and to cause their respective subsidiaries and their respective directors, officers and employees not to, and to use its reasonable best efforts to cause its other respective representatives not to:

•

solicit, assist, initiate, knowingly encourage or otherwise facilitate (including by way of furnishing confidential information or entering into any form of agreement, arrangement or understanding (other than a confidentiality agreement pursuant to certain provisions of the arrangement agreement)), any inquiry, proposal or offer that constitutes or may reasonably be expected to constitute or lead to an acquisition proposal, except as expressly permitted in the arrangement agreement;

•

enter into, engage in, continue or otherwise participate in any discussions or negotiations with any person (other than the other party to the arrangement agreement, its subsidiaries or affiliates) in respect of any inquiry, proposal or offer that constitutes or may reasonably be expected to constitute or lead to an acquisition proposal, it being acknowledged and agreed that, provided a party is then in compliance with its obligations under its non-solicitation covenants, such party may (i) advise any person of the restrictions of the arrangement agreement; (ii) advise a person who has submitted a written acquisition proposal of the conclusion (without further communication) that its acquisition proposal does not constitute a superior proposal or (iii) communicate with any person solely for the purposes of clarifying the terms of any inquiry, proposal or offer made by such person;

•	accept or enter into, or publicly propose to accept or enter into, any letter of intent, agreement in principle, agreement, arrangement or undertaking relating to any acquisition proposal (other than a confidentiality agreement pursuant to certain provisions of the arrangement agreement);

•

(i) modify or qualify in any manner adverse to (or publicly propose to do so) the other party, or withdraw, its board recommendation; (ii) make any approval, endorsement or recommendation (or publicly propose to do so) by its board of any tender offer, take-over bid or other acquisition proposal (other than a recommendation against such offer, bid or acquisition proposal); (iii) fail to include its board recommendation in the proxy statement or proxy circular, as the case may be; (iv) fail to publicly reaffirm its board recommendation within five business days after the other party reasonably requests in writing after a material event or development (other than an event described in clause (v) below) (or within such fewer number of days as remains before the day that is two business days before the special meeting or TransGlobe’s shareholder meeting, as applicable); (v) (x) as to VAALCO, fail to recommend, in a solicitation/recommendation statement on Schedule 14D-9 against any acquisition proposal that is a tender offer or exchange offer subject to Regulation 14D promulgated under the Exchange Act within 10 business days after commencement of such tender offer or exchange offer, or (y) as to TransGlobe, in the case of a take-over bid subject to National Instrument 62-104 - Takeover Bids and Issuer Bids, fail to unanimously (subject to abstentions of any conflicted director) recommend, in a directors’ circular, rejection of such take-over bid within 15 days of the date of such take-over bid; or (vi) take no position or a neutral position with respect to an acquisition proposal for more than five business days after the public announcement of

TABLE OF CONTENTS

such acquisition proposal (it being understood that taking no position or a neutral position with respect to an acquisition proposal for a period of no more than five business days after the public announcement of such acquisition proposal will not be considered to be a change in recommendation provided (other than with respect to an event described in clause (v)(x) above as to VAALCO), its board of directors has rejected such acquisition proposal and reaffirmed the board recommendation before the end of such five business day period); or

•	make any public announcement or take any other action inconsistent with the approval, recommendation or declaration of advisability of the board of directors of the transactions contemplated in the arrangement agreement.

If, at any time prior to a party obtaining the approval of its stockholders or shareholders, as applicable, TransGlobe or VAALCO, as applicable, receives a request for material non-public information or to enter into discussions, from a person that proposes an unsolicited bona fide written acquisition proposal that did not result from a breach of the arrangement agreement (and which has not been withdrawn) and such party’s board of directors determines, in good faith after consultation with its outside financial and legal advisors, that such acquisition proposal constitutes or would reasonably be expected to constitute a superior proposal (disregarding, for the purposes of such determination, any due diligence or access condition to which such acquisition proposal is subject) then, and only in such case, TransGlobe or VAALCO, as applicable, may (i) enter into, participate in, facilitate and maintain discussions or negotiations with, and otherwise cooperate with or assist, the person making such acquisition proposal, and (ii) provide the person making such acquisition proposal with, or access to, confidential information regarding such party and its subsidiaries, but only to the extent that the other party had previously been, or is concurrently, provided with, or access to, the same information, if, and only if: (x) such party has entered into a confidentiality agreement on terms no less favorable in aggregate to such party than the confidentiality agreement entered into between TransGlobe and VAALCO in connection with the arrangement agreement (provided such confidentiality agreement will not be required to have any standstill provisions), a copy of which must be provided to the other party promptly and in any event prior to providing such person with any such copies, access or disclosure, and provided further that such confidentiality agreement will not contain any exclusivity provision or other term that would restrict, in any manner, the party’s ability to consummate the transactions contemplated hereby or to comply with its disclosure obligations to the other party pursuant to the arrangement agreement, and any such copies, access or disclosure provided to such person will have already been, or will substantially concurrently be, provided to the other party; (y) the person submitting the acquisition proposal was not restricted from making such acquisition proposal pursuant to an existing confidentiality, standstill, non-disclosure, use, business purpose or similar agreement, restriction or covenant with such party or any of its subsidiaries; and (z) such party has been, and continues to be, in material compliance with its non-solicitation covenants.

The board of directors of each of TransGlobe and VAALCO may not make a change in its recommendation in connection with an acquisition proposal unless:

•	such board of directors has determined that the acquisition proposal constitutes a superior proposal;

•	the approval of that party’s stockholders or shareholders, as applicable, has not been obtained;

•	such party has been and continues to be, in material compliance with its non-solicitation covenants; and

•

the party first provides the other party with written notice of a superior proposal and a five business day response period (during which period, the other party may propose amendments to the arrangement, including to the consideration) and, if the other party has proposed to amend the terms of the arrangement, the board of directors of the party that received an acquisition proposal, after consultation with its outside financial and legal advisors, determines that the acquisition proposal remains a superior proposal compared to the other party’s proposed amendment to the terms of the arrangement.

Notwithstanding the foregoing, the boards of directors of each of TransGlobe and VAALCO may effect a change in recommendation in response to an intervening event (as such term is defined in the section of this proxy statement entitled “The Arrangement Agreement and the Plan of Arrangement—Non-Solicitation of Alternative Transactions and Changes in Recommendation”), if and only if all of the following are satisfied:

•	such party’s board of directors has determined in good faith (after consultation with its outside legal counsel) that the failure to effect a change in recommendation in response to such intervening event would be inconsistent with its fiduciary duties under applicable law;

TABLE OF CONTENTS

•	the approval of that party’s stockholders or shareholders, as applicable, has not been obtained;

•

such party shall have promptly provided the other party with a notice in writing that it intends to effect a change in recommendation in response to such intervening event, describing in reasonable detail the underlying facts giving rise to, and the reasons for making, such change in recommendation (it being understood that such notice shall not constitute a change in recommendation for purposes of the arrangement agreement);

•	a five business day response period shall have elapsed from the date the other party received the notice referred to in the previous bullet; and

•

if the other party has proposed to amend the terms of the arrangement, the board of directors of the party that has experienced an intervening event shall have determined in good faith, after consultation with its outside legal advisors, that the failure to effect a change in recommendation in response to such intervening event would be inconsistent with its fiduciary duties under applicable law.

Notwithstanding any change in recommendation, unless the arrangement agreement has been terminated in accordance with its terms, the party whose board of directors changed its recommendation must still hold its stockholder or shareholder meeting, as applicable, and allow its stockholders or shareholders, as applicable, to vote on the arrangement, and such party is not permitted, except as required by applicable law, to submit to a vote of its stockholders or shareholders, as applicable, any acquisition proposal other than the arrangement agreement prior to the termination of the arrangement agreement.

•

after the date of the arrangement agreement, any applicable law or order has been enacted that makes consummation of the arrangement illegal or otherwise prohibits or enjoins TransGlobe, VAALCO or AcquireCo from consummating the arrangement and such law, order or enjoinment has become final and non-appealable;

•

the TransGlobe resolution has not been approved at TransGlobe’s shareholder meeting except that the right to terminate the arrangement agreement will not be available to any party whose failure to fulfill any of its obligations or breach of any of its representations or warranties under the arrangement agreement has been the cause of, or resulted in, such failure to receive the approval from TransGlobe shareholders;

If the arrangement agreement is terminated in accordance with its terms, there will be no liability on the part of any party thereto except for such party’s willful breach of the arrangement agreement, and certain provisions of the arrangement agreement that will survive such termination, including those provisions related to the payment of termination fees described below.

•	the arrangement agreement is terminated by either party due to a failure to obtain the approval of VAALCO stockholders following a change in recommendation by VAALCO; or

•

the arrangement agreement is terminated by (i) either party due to (A) the effective date of the arrangement not occurring prior to the outside date or (B) a failure to obtain the approval of VAALCO stockholders, or (ii) by TransGlobe if VAALCO is in breach of any representation or, warranty or fails to perform any covenant or agreement under the arrangement agreement that would cause certain conditions to closing not to be satisfied, and such conditions are incapable of being satisfied by the outside date, but, in each case, only if in these termination events:

○	prior to such termination, a bona fide acquisition proposal for VAALCO has been made or publicly announced by any person other than TransGlobe (and, if the special meeting is held, is not withdrawn at least five business days prior to the date of the special meeting); and

○

on or prior to the 12 month anniversary of the date of such termination, (i) VAALCO or one or more of its subsidiaries enters into a definitive agreement in respect of an acquisition proposal for VAALCO and such acquisition proposal is later consummated (whether or not on or prior to the 12 month anniversary of the date of such termination) or (ii) an acquisition proposal for VAALCO has been consummated; provided that for the purposes of this discussion on termination fees, a reference to “20 per cent” in the definition of “acquisition proposal” will be deemed to be a reference to “50 per cent.”

VAALCO’s Reasons for the Arrangement

In evaluating the arrangement, including the issuance of VAALCO common stock to TransGlobe shareholders in connection with the arrangement, the VAALCO board of directors consulted with VAALCO’s senior management, outside legal counsel and independent financial advisor. In recommending that VAALCO stockholders vote in favor

TABLE OF CONTENTS

of the amendment proposal and the share issuance proposal, the VAALCO board of directors also considered a number of factors that it believed supported its determination. For a more detailed discussion of the reasoning of the VAALCO board of directors, see “The Arrangement—VAALCO’s Reasons for the Arrangement” and “The Arrangement—Recommendations of the VAALCO Board of Directors” sections of this proxy statement.

Recommendation of the VAALCO Board of Directors

After careful consideration, the VAALCO board of directors has determined that it is advisable and in the best interests of VAALCO and its stockholders to consummate the arrangement as contemplated by the arrangement agreement. Accordingly, the VAALCO board of directors unanimously recommends that VAALCO stockholders vote:

•	“FOR” the amendment proposal; and

•	“FOR” the share issuance proposal.

Opinion of Financial Advisor to VAALCO

VAALCO has engaged Stifel to act as its financial advisor in connection with the proposed arrangement. In connection with Stifel’s engagement, Stifel delivered to the VAALCO board of directors an oral opinion on July 13, 2022, subsequently confirmed in writing by delivery of a written opinion, dated July 13, 2022, that, as of the date of Stifel’s opinion, the consideration to be paid by VAALCO to the TransGlobe shareholders pursuant to the terms and conditions of the arrangement agreement was fair to VAALCO, from a financial point of view.

With Stifel’s consent, the full text of Stifel’s opinion, which describes the assumptions made, procedures followed, matters considered and limitations and qualifications on the review undertaken, is attached as Annex D to this proxy statement and is incorporated into this proxy statement by reference. The description of Stifel’s opinion set forth in this proxy statement is qualified in its entirety by reference to the full text of Stifel’s opinion. Stifel’s opinion was prepared at the request and for the benefit and use of the VAALCO board of directors (in its capacity as such) in connection with its evaluation of the consideration to be paid by VAALCO from a financial point of view and did not address any other terms, aspects or implications of the arrangement. Stifel expressed no opinion as to the relative merits of the arrangement or any other transactions or business strategies discussed by the VAALCO board of directors as alternatives to the arrangement or the decision of the VAALCO board of directors to proceed with the arrangement, nor did Stifel express any opinion on the structure, terms (other than the consideration to the extent specified in Stifel’s opinion) or effect of any other aspect of the arrangement, including, without limitation, any Pre-Acquisition Reorganization (as defined in the arrangement agreement), any terms, aspects or implications of any voting agreement or any other agreement, arrangement or understanding to be entered into in connection with or contemplated by the arrangement or the other transactions contemplated by the arrangement agreement. Stifel’s opinion does not constitute a recommendation as to any action the VAALCO board of directors should take in connection with the arrangement or the other transactions contemplated by the arrangement agreement or any aspect thereof and is not a recommendation to any director of VAALCO on how such person should vote or act with respect to the arrangement or related transactions and proposals. Stifel’s opinion also does not constitute a recommendation to any security holder as to how such holder should vote or act with respect to the arrangement or related transactions or proposals. For additional information, see “The Arrangement—Opinion of Financial Advisor to VAALCO” section of this proxy statement.

The Support and Voting Agreements

On July 13, 2022, in connection with the signing of the arrangement agreement, each of VAALCO and TransGlobe entered into support and voting agreements with one another’s directors and certain members of one another’s respective executive teams, in their capacity as shareholders or stockholders, as applicable, pursuant to which such shareholders or stockholders, as applicable, have agreed, among other things, to vote their respective TransGlobe common shares in favor of the TransGlobe resolution, in the case of TransGlobe shareholders, and vote their respective shares of VAALCO common stock in favor of the amendment proposal and share issuance proposal, in the case of VAALCO stockholders. As of August 24, 2022, the record date of TransGlobe’s shareholder meeting, TransGlobe shareholders subject to support and voting agreements with VAALCO, collectively, owned, directly or indirectly, or exercised control or direction over, an aggregate of approximately 1.3% of the outstanding TransGlobe common shares on a non-diluted basis and approximately 2.2% of the outstanding TransGlobe common shares on a partially diluted basis, assuming exercise or vesting of their TransGlobe options. As of the record date of the special

TABLE OF CONTENTS

meeting, VAALCO stockholders subject to support and voting agreements with TransGlobe, collectively, owned, directly or indirectly, or exercised control or direction over, an aggregate of approximately 1.6% of the outstanding shares of VAALCO common stock on a non-diluted basis and approximately 2.6% of the outstanding shares of VAALCO common stock on a partially diluted basis, assuming exercise or vesting of their VAALCO options. Copies of the form of support and voting agreements are attached to this proxy statement as Annex B and Annex C.

Board of Directors Following the Arrangement

VAALCO has agreed with TransGlobe that it will take all actions necessary to ensure that, as of the effective time, the board of directors of VAALCO will consist of: (i) the four existing members of the VAALCO board of directors: Andrew L. Fawthrop, George Maxwell, Cathy Stubbs and Fabrice Nze-Bekale; and (ii) three of the members of TransGlobe’s existing board of directors: David Cook, Edward LaFehr and Timothy Marchant. The parties have agreed that Andrew L. Fawthrop will continue as the chairman of the VAALCO board of directors. See “The Arrangement—Board of Directors Following the Arrangement” section of this proxy statement.

Management Following the Arrangement

VAALCO anticipates that its Chief Executive Officer and Chief Financial Officer will remain with VAALCO following the consummation of the arrangement.

Interests of VAALCO Directors and Executive Officers in the Arrangement

No current VAALCO directors or executive officers having served at any time since the beginning of 2021 own TransGlobe common shares as of the date of this proxy statement. None of VAALCO’s directors or executive officers or their associates has any substantial financial interest, direct or indirect, in the arrangement or the issuance of VAALCO common stock to TransGlobe shareholders under the arrangement, other than being a director or executive officer of VAALCO and a stockholder of VAALCO.

Accounting Treatment

VAALCO prepares its financial statements in accordance with U.S. GAAP. The arrangement will be accounted for as a business combination using the acquisition method of accounting. VAALCO will be treated as the acquirer for accounting purposes. VAALCO will record assets acquired, including identifiable intangible assets, and liabilities assumed from TransGlobe at their respective preliminary estimated fair values at the date of completion of the arrangement. For additional information, see “The Arrangement—Accounting Treatment” section of this proxy statement.

Court Approvals

The arrangement requires approval by the Court under Section 193 of the ABCA. On August 29, 2022, TransGlobe obtained the interim order authorizing and directing TransGlobe to call, hold and conduct TransGlobe’s shareholder meeting and submit the arrangement to TransGlobe shareholders for approval. Under the arrangement agreement, TransGlobe is required to seek the final order as soon as reasonably practicable, but in any event not later than five business days following the approval of the TransGlobe resolution by TransGlobe shareholders at TransGlobe’s shareholder meeting. The Court hearing in respect of the final order is expected to take place on or about September 29, 2022 at 2:00 PM (Calgary Time) in Alberta, Canada, or as soon thereafter as is reasonably practicable.

Regulatory Approvals

Subsidiaries of TransGlobe (the “TransGlobe Egyptian Parties”) are parties to two concession agreements with the Egyptian General Petroleum Corporation (the “EGPC”) and the Arab Republic of Egypt (the “Egyptian Government”) that provide exclusive rights to explore for and develop oil and gas in the South Ghazalat Area Western Desert and the merged development areas of West Bakr, West Gharib and Northwest Gharib Onshore (the “Concession Agreements”). The Concession Agreements provide that the TransGlobe Egyptian Parties may not assign any of their rights, privileges, duties or obligations under the Concession Agreements, directly or indirectly,

TABLE OF CONTENTS

without the written consent of the Egyptian Government (the “Assignment Provisions”). In addition, if the Assignment Provisions are triggered, (i) the EGPC has the right to acquire the interest intended to be assigned on the same conditions, if it elects to do so within 90 days of receiving the final conditions (including the value of each assignment); and (ii) the TransGlobe Egyptian Parties would be required to pay a non-recoverable assignment fee to the EGPC in an amount equal to 10% of the value of each assignment deal upon the Egyptian Government’s approval of any assignment.

Neither VAALCO nor TransGlobe believes that the arrangement triggers the Assignment Provisions. Following announcement of the arrangement, the EGPC delivered correspondences to each of VAALCO and TransGlobe requesting data and documents relating to the arrangement, the value of the deal and TransGlobe’s share in the relevant Egyptian assets. VAALCO and TransGlobe have engaged, and are continuing to engage, in discussions with the office of the Minister of Petroleum and the EGPC, for the purpose of clarifying that the arrangement does not, and is not deemed to, trigger the Assignment Provisions in the Concession Agreements.

If the arrangement did trigger the Assignment Provisions, (i) consummation of the arrangement would require the written approval of the Egyptian Government; and (ii) the TransGlobe Egyptian Parties would be required to pay a non-recoverable assignment fee to the EGPC in an amount equal to 10% of the value of each assignment deal upon the Egyptian Government’s approval of any assignment. See “Risk Factors—TransGlobe’s Concession Agreements in Egypt contain assignment provisions and, if such assignment provisions were triggered by the arrangement, it could adversely affect the ability to consummate the arrangement or the benefits anticipated to be realized from the arrangement in a material manner.”

No Appraisal Rights

Under the DGCL, holders of shares of VAALCO common stock are not entitled to appraisal rights in connection with the arrangement or any of the matters to be acted on at the special meeting.

TABLE OF CONTENTS

SUMMARY OF SIGNIFICANT IFRS TO U.S. GAAP DIFFERENCES

The financial information of TransGlobe incorporated by reference into this proxy statement has been prepared and presented in accordance with IFRS. Certain differences exist between IFRS and U.S. GAAP, which might be material to the financial information incorporated by reference into this proxy statement.

The principal differences between U.S. GAAP and IFRS which might be material in the preparation of TransGlobe’s consolidated financial statements are described below. The following summary does not include all differences that exist between IFRS and U.S. GAAP and is not intended to provide a comprehensive listing of all such differences specifically related to VAALCO, TransGlobe or the industry in which VAALCO and TransGlobe operate.

The differences described below reflect only those differences in accounting policies in force at the time of the preparation of the historical financial information of TransGlobe. There has been no attempt to identify future differences between IFRS and U.S. GAAP as the result of prescribed changes in accounting standards, transactions or events that may occur in the future.

Impairment of Long-Lived Assets

Under both U.S. GAAP and IFRS, long-lived assets are tested for impairment when events or changes in circumstances indicate that the carrying amounts may be impaired. Under U.S. GAAP, the asset group is first tested for recoverability by determining if its carrying amount exceeds the expected future cash flows from the asset group on an undiscounted basis. If the asset group is determined to not be recoverable, an impairment expense is recorded for the excess of the asset group’s carrying amount over its fair value. Further, future reversal of a previously recognized impairment loss is prohibited.

Under IFRS, when an impairment indicator is determined to exist, an impairment expense is recorded for the excess of the cash generating unit carrying amount over its recoverable amount, determined as the greater of its fair value less costs of disposal and its value in use. Impairment expense previously recorded is reversible in subsequent periods under certain conditions.

Exploration and Evaluation Costs

Under both U.S. GAAP and IFRS, there are two broad methods typically used to account for exploration and evaluation costs, namely, successful efforts and full cost. However, there are further variations of these two approaches in practice and accordingly differences may exist in the accounting for exploration and evaluation costs, depending on the policy elected by the entity and any variation applied. In particular, under IFRS, an accounting policy is determined for each type of exploration and evaluation expenditure of either immediate expense or capitalization as an asset and such policy is applied consistently.

Under the successful efforts method, certain costs incurred during exploration and costs incurred in finding, acquiring and developing reserves are typically capitalized on a field-by-field basis. Capitalized costs are allocated to commercially viable hydrocarbon reserves and depleted as production occurs. U.S. GAAP contains more prescriptive guidance on the types of exploration costs that can be capitalized – in particular, geological and geophysical activities, costs of carrying and retaining undeveloped properties and costs associated with exploratory dry holes recognized as an expense as they are incurred. Costs of drilling exploratory and exploratory-type test wells are capitalized pending determination of whether such well can produce proved reserves.

Under the full cost method, all costs incurred in searching for, acquiring and developing the reserves in a large geographic cost center or pool, such as a country, are capitalized. The cost pools are then depleted on a country basis as production occurs. If exploration efforts in the country or the geological formation are wholly unsuccessful, the costs are expensed. This method generally results in deferral of costs during the exploration and development phase, and greater subsequent depletion charges, compared to the successful efforts method.

Under U.S. GAAP, the testing for impairment of exploration and evaluation assets recognized under the successful efforts methods are typically performed on a field by field. Under U.S. GAAP, impairment tests of exploration and evaluation asset are recognized under the full cost methods are typically performed at a geographical level. Under IFRS, the entity is permitted to elect to group exploration and evaluation assets with producing assets for purposes of testing impairment.

Further, U.S. GAAP generally applies the same accounting principles for testing impairment of exploration and evaluation assets recognized under the successful method as those applied to other long-lived assets. However, under

TABLE OF CONTENTS

IFRS, specific requirements exist for exploration and evaluation assets in which an entity is not required to assess for impairment triggers for such assets until the entity has sufficient information to assess the commercial viability and feasibility of extraction. IFRS also contains specific indicators for impairment relating to exploration and evaluation assets.

Depletion, Depreciation & Amortization

Under both U.S. GAAP and IFRS, capitalized exploration, evaluation and development costs are often amortized using the units-of-production method based on estimated recoverable reserves. Under U.S. GAAP, an entity often determines the unit of production based on the total amount of proved developed reserves and total proved reserves expected. Under IFRS, there is no prescribed basis used for the unit of production calculation and the entity may elect a different policy including using either proved developed reserves, total proved or both proved and probable reserves.

Reclamation and Remediation Liabilities

Under U.S. GAAP, the initial recognition of asset retirement obligation is based on the fair value of the reclamation and remediation liability, generally utilizing a present value technique to estimate the liability and discounted at a credit-adjusted risk-free interest rate. Subsequently, period-to-period revisions to either the timing or amount of the original estimate of undiscounted cash flows are treated as separate layers of the obligation.

Under IFRS, initial recognition of reclamation and remediation liability is generally measured as the best estimate of the expenditure to settle the obligation utilizing a present value technique to estimate the liability, discounted at a pretax rate that reflects current market assessments of the time value of money and the risks specific to the liability. Subsequently, period-to-period revisions for changes in the estimate of expected undiscounted cash flows or discount rate is re-measured for the entire obligation by using an updated discount rate that reflects current market conditions as of the balance sheet date.

Joint Arrangements

Under U.S. GAAP, a joint venture is defined as an entity whose operations and activities are jointly controlled by its equity investors. Joint ventures are accounted for using the equity method of accounting. Proportionate consolidation is used in the oil and gas and mining and extractive industries, when working interest owners join together in the development and operation of a jointly-owned or unitized property outside a separate legal entity pursuant to a written agreement.

IFRS addresses two types of joint arrangements: (1) joint operations and (2) joint ventures, both distinguished by the rights and obligations of the parties involved. In a joint operation, an entity has rights to the underlying assets and obligations for the liabilities of the arrangement and recognizes its share of the assets, liabilities, revenues, and expenses arising from its interest. In a joint venture, the equity method of accounting is used and requires the use of a separate legal entity. Unlike U.S. GAAP, the existence of a separate legal entity is not sufficient evidence to conclude that an arrangement is a joint venture.

Leases

Under U.S. GAAP, leases are required to be classified as operating leases or finance leases for lessees, which is relevant for determining the timing of recognition and presentation on the income statement, while IFRS contains one classification (effectively finance leases) for lessees. Under both U.S. GAAP and IFRS, lessees are required to record a right-of-use (“ROU”) asset (representing the right to use the underlying asset) and a corresponding lease liability (representing lease payments to be made in the future) at lease commencement.

Under U.S. GAAP for a finance lease, the ROU asset is amortized on a straight-line basis and a separate interest expense is recognized for the lease liability. The amortization expense and interest relating to the finance lease results in a front-loaded expense profile. Under U.S. GAAP for an operating lease, the total lease expense is recognized on a straight-line basis over the least term.

Under IFRS, there is a single accounting model in which the ROU asset is generally amortized on a straight-line basis. This amortization, when combined with the interest on the lease liability, results in a front-loaded expense profile.

TABLE OF CONTENTS

Under IFRS and a finance lease under U.S. GAAP, interest expense on the lease liability and amortization of the ROU asset are presented separately in the income statement whereas for an operating lease under U.S. GAAP rent expense is presented in a single line item.

Share-based Payments

Under both U.S. GAAP and IFRS, share-based payments are initially recorded in the financial statements on the basis of their grant-date fair value (with certain exceptions). The subsequent accounting for such awards depends on the classification as equity or liability awards.

While the fundamental principles are similar between U.S. GAAP and IFRS, there are many differences in detail that may lead to significant differences in practice including the treatment of share-based awards with graded vesting conditions and those subject to forfeiture. For example, under U.S. GAAP, for graded vesting share-based payment awards that only contain a service condition, an entity has to choose as an accounting policy either to (1) recognize a charge on an accelerated basis to reflect the vesting as it occurs or (2) amortize the entire grant on a straight-line basis over the longest vesting period. Under IFRS, an entity must recognize a charge on an accelerated basis to reflect the vesting as it occurs.

Similarly, under U.S. GAAP, for awards with service conditions, an entity makes an entity-wide accounting policy election to either (1) estimate the total number of awards for which the employee’s requisite service period or nonemployee’s vesting period will not be rendered (i.e., estimate expected forfeitures) or (2) account for forfeitures when they occur. Under IFRS, an entity is required to estimate the amount of forfeitures.

Income Taxes

Under U.S. GAAP, deferred taxes are recognized for temporary differences arising from the initial recognition of assets acquired or liabilities assumed. Under IFRS, deferred income taxes are not recognized for temporary differences arising from the initial recognition of an asset or liability in a transaction that (i) is not a business combination, and (ii) affects neither accounting nor taxable profit.

U.S. GAAP prohibits recognition of deferred tax consequences for differences that arise from changes in exchange rates or indexing for tax purposes for those foreign subsidiaries that are required to use historical rates to remeasure nonmonetary assets and liabilities from the local currency into the functional currency. Under IFRS, deferred tax assets or liabilities are recognized for temporary differences related to nonmonetary assets or liabilities that are remeasured from the local currency into the functional currency for book purposes using historical exchange rates, but are reported in local currency for tax purposes using current exchange rates.

Marketable Equity Securities

U.S. GAAP requires investments in equity securities to be measured at fair value, with changes in fair value recognized in net income, unless equity securities do not have a readily determinable fair value. Under IFRS, equity securities designated as fair value through other comprehensive income are carried at fair value and changes in fair value are recognized in other comprehensive income, which is not subsequently charged to earnings.

UNAUDITED PRO FORMA COMBINED FINANCIAL INFORMATION

Introduction

On July 13, 2022, VAALCO, AcquireCo and TransGlobe entered into the arrangement agreement whereby AcquireCo, an indirect wholly-owned subsidiary of VAALCO, will acquire all of the issued and outstanding TransGlobe common shares with TransGlobe continuing as a direct wholly-owned subsidiary of AcquireCo and an indirect wholly-owned subsidiary of VAALCO. Upon completion of the arrangement, TransGlobe shareholders will receive 0.6727 of a share of VAALCO common stock for each TransGlobe common share.

The unaudited pro forma combined financial information of VAALCO is comprised of (i) the unaudited pro forma combined balance sheet as of June 30, 2022, after giving effect to the arrangement as if it had occurred on June 30, 2022; (ii) the unaudited pro forma combined statements of operations for the six months ended June 30, 2022, and for the year ended December 31, 2021, after giving effect to the arrangement as if it had occurred on January 1, 2021; and (iii) the accompanying notes (collectively, the “Unaudited Pro Forma Combined Financial Information”).

The Unaudited Pro Forma Combined Financial Information has been derived from the (i) historical unaudited condensed consolidated financial statements and the related notes of VAALCO and TransGlobe, respectively as of and for the six months ended June 30, 2022, and (ii) the historical audited consolidated financial statements and the related notes of VAALCO and TransGlobe respectively for the year ended December 31, 2021.

The Unaudited Pro Forma Combined Financial Information has been prepared by VAALCO management for illustrative purposes only. The Unaudited Pro Forma Combined Financial Information does not purport to represent what the actual results of operations of VAALCO or the combined entity would have been had the arrangement occurred on the respective dates assumed, nor is it indicative of the future results of VAALCO. The Unaudited Pro Forma Combined Financial Information and underlying pro forma adjustments are based upon currently available information and include certain estimates and assumptions made by VAALCO management; accordingly, actual results could differ materially from the Unaudited Pro Forma Combined Financial Information.

The Unaudited Pro Forma Combined Financial Information has been prepared in accordance with Article 11 of Regulation S-X as amended by the final rule, Release No. 33-10786 “Amendments to Financial Disclosures about Acquired and Disposed Businesses,” using assumptions set forth in the notes herein. The Unaudited Pro Forma Combined Financial Information does not reflect any cost savings, operating synergies or revenue enhancements that the combined entity may achieve as a result of the arrangement. The pro forma adjustments reflected in the accompanying Unaudited Pro Forma Combined Financial Information reflect estimates and assumptions made by our management that we believe to be reasonable. Significant estimates and assumptions include, but are not limited to, the timing of close of the arrangement, and the preliminary purchase price allocation.

The Unaudited Pro Forma Combined Financial Information should be read together with (i) VAALCO’s audited consolidated financial statements and related notes included in its Annual Report on Form 10-K for the year ended December 31, 2021, filed with the SEC on March 11, 2022; (ii) TransGlobe’s audited consolidated financial statements and related notes included in its Annual Report on Form 40-F for the year ended December 31, 2021, filed with the SEC on March 17, 2022; (iii) VAALCO’s unaudited condensed consolidated financial statements and related notes included in its Quarterly Report on Form 10-Q for the six months ended June 30, 2022, filed with the SEC on August 10, 2022; and (iv) TransGlobe’s unaudited condensed consolidated financial statements and related notes included in its Report of Foreign Issuer on Form 6-K, filed with the SEC on August 10, 2022.

Notes to Unaudited Pro Forma Combined Financial Statements

1. Basis of Preparation

This Unaudited Pro Forma Combined Financial Information has been derived from the unaudited condensed consolidated financial statements of VAALCO and TransGlobe as of and for the six months ended June 30, 2022, and the audited consolidated financial statements of VAALCO and TransGlobe as of and for the year ended December 31, 2021. The Unaudited Pro Forma Combined Financial Information has been prepared in accordance with Article 11 of Regulation S-X as amended by the final rule, Release No. 33-10786 “Amendments to Financial Disclosures about Acquired and Disposed Businesses,” using assumptions set forth in the notes herein.

The unaudited pro forma combined balance sheet as of June 30, 2022, gives effect to the arrangement as if it had occurred on June 30, 2022. The unaudited pro forma combined statements of operations for the six months ended June 30, 2022, and for the year ended December 31, 2021, give effect to the arrangement as if it had occurred on January 1, 2021.

The consolidated financial statements of VAALCO were prepared in accordance with U.S. GAAP. The consolidated financial statements of TransGlobe were prepared in accordance with IFRS. As such, the Unaudited Pro Forma Combined Financial Information includes adjustments to align the accounting policies of TransGlobe to those of VAALCO.

The Unaudited Pro Forma Combined Financial Information and underlying pro forma adjustments are based upon currently available information and include certain estimates and assumptions made by management; accordingly, actual results could differ materially from the pro forma information. Management believes the assumptions provide a reasonable and supportable basis for presenting the estimated significant effects of the arrangement. The Unaudited Pro Forma Combined Financial Information is provided for illustrative purposes only and may or may not provide an indication of results in the future.

2. Application of U.S. GAAP and Reclassification Adjustments

The consolidated financial statements of TransGlobe were prepared in accordance with IFRS. For purposes of preparing the Unaudited Pro Forma Combined Financial Information, the financial information of TransGlobe has been adjusted to give effect to the material differences between IFRS and U.S. GAAP, to the extent that such historical IFRS and U.S.GAAP differences are not affected by the adjustments relating to preliminary purchase price allocation described in Note 3 below. Other differences impacted by the preliminary purchase price allocation are included as other “pro forma adjustments” as described in Note 3 and 4 below. Further, certain adjustments to TransGlobe’s financial information are required to conform TransGlobe’s presentation and classification policies to those of VAALCO, as described below.

2.2	U.S. GAAP adjustments to the unaudited pro forma combined statement of operations for the six months ended June 30, 2022, and for the year ended December 31, 2021

(a)	Adjustment to derecognize the impairment reversal previously recognized in accordance with IFRS. Under U.S. GAAP, the reversal of an impairment loss for assets to be held and used is prohibited.

(b)

Adjustment to reflect differences between accounting for leases between IFRS and U.S. GAAP. Under IFRS, the amortization of the right of use asset relating to all leases are recognized on a straight-line basis and accounted for as “amortization” expense within Depreciation, depletion and amortization. Under U.S. GAAP, leases are classified as either finance leases or operating leases; for operating leases, the amortization is treated a “lease costs” and classified as part of Production cost or General and administrative expense depending on the type of lease. The impact of treating such leases as operating leases under U.S. GAAP on interest cost are insignificant.

3. Preliminary Acquisition Accounting and Other Pro Forma adjustments and Assumptions

(a)	Consideration for the Combination and Purchase Price Allocation

The arrangement will be accounted for using the acquisition method of accounting for business combinations in accordance with ASC 805, Business Combinations. VAALCO will be treated as the acquirer for accounting purposes based on the evaluation of the following facts and circumstances:

•	VAALCO’s stockholders will hold a majority of the voting power of the combined company

•	VAALCO’s directors are expected to comprise a majority of the governing body of the combined company

•	VAALCO’s senior management will comprise the senior management of the combined company

•	Under the terms of the arrangement, VAALCO is expected to pay a premium over the pre-combination fair value of the equity interest acquired from TransGlobe stockholders.

The purchase consideration for the arrangement will be determined based on the number of VAALCO shares issued in exchange for TransGlobe common shares on the date of the arrangement. VAALCO will allocate the purchase consideration based on the TransGlobe assets acquired, including identifiable intangible assets, and liabilities assumed from TransGlobe at their respective preliminary estimated fair values at the date of completion of the arrangement.

VAALCO’s allocation of the preliminary estimated purchase consideration with respect to the arrangement is based on estimate of, and assumptions related to, the fair value of assets to be acquired and liabilities to be assumed as of June 30, 2022, using current available information. The preliminary purchase price allocation is subject to change due to several factors, including but not limited to:

•	Changes in the estimated fair value of VAALCO’s common stock consideration transferred depending on its market price at the date of closing; and

•	Changes in the estimated fair value of TransGlobe’s assets acquired and liabilities assumed as of the date of the arrangement, which could result from changes in future oil and natural gas commodity prices, reserve estimates, interest rates, discount rates as well as other factors.

Because the Unaudited Pro Forma Combined Financial Information has been prepared based on these preliminary estimates, the resulting effect on the financial position and results of operation of the combined business may be materially different from the pro forma amounts included herein.

VAALCO expects to finalize the purchase price allocation as soon as reasonably practicable after completing the arrangement, and upon consideration of any incremental information as part of the finalization of the measurement process. The finalization of the purchase price allocation will not extend beyond the one-year measurement period provided under ASC 805.

TABLE OF CONTENTS

The following is a preliminary estimate of the consideration expected to be paid to effect the combination with TransGlobe:

Purchase Consideration
Estimate of share consideration expected to be transferred to TransGlobe shareholders
Number of TransGlobe common shares outstanding as of July 29, 2022			73,309,064
Multiplied by the Exchange ratio			0.6727
VAALCO shares expected to be issued			49,315,007
Closing price of VAALCO shares on July 29, 2022			$5.93
Estimated fair value of share consideration¹			$292,437,994

1	Resulting in $4,932 thousand in common shares and $287,506 thousand of additional paid-in capital as of June 30, 2022.

For the purposes of these unaudited pro forma combined financial statements, the fair value of share consideration to be transferred is estimated using the closing price of VAALCO shares of $5.93 per share as of July 29, 2022, the latest practicable date before the date of this proxy statement.

The estimated consideration for VAALCO’s combination with TransGlobe reflected in these unaudited pro forma combined financial statements does not purport to represent the actual consideration when the proposed combination with TransGlobe is consummated. In accordance with ASC 805, the fair value of any equity securities issued as part of the consideration paid will be measured on the closing date of the combination at the then-current market price. This requirement will likely result in a per share equity component different from the $5.93 assumed in these unaudited pro forma combined financial statements, and that difference may be material. An increase or decrease in the price per VAALCO share assumed in these unaudited pro forma combined financial statements by 5% will increase or decrease the estimated purchase price by approximately $14,622 thousand; an increase or decrease in the price per VAALCO share of 10% will increase or decrease the estimated purchase price by $29,244 thousand; and an increase or decrease in the price per VAALCO share of 25% will increase or decrease the estimated purchase price by $73,109 thousand. Such increases or decreases would be reflected in these unaudited pro forma combined financial statements as an increase or decrease in gain on acquisition or goodwill may be recognized as shown in the table below:

(in thousands)
	Increase in price per VAALCO share			Decrease in price per VAALCO share
% Increase/Decrease	5%	10%	25%	5%	10%	25%

(A)

Adjustment to reflect the settlement of TransGlobe’s stock options, RSUs and PSUs following the pre-combination acceleration of vesting on change of control under the terms of the original awards and the arrangement agreement as though the arrangement occurred on June 30, 2022. Such awards will be cash settled by TransGlobe prior to the closing of the arrangement.

(B)	Adjustment to reflect the fair value of TransGlobe’s Crude oil and natural gas properties, equipment and other successful efforts method, net as of the arrangement date as though the arrangement occurred on June 30, 2022.

(C)	Adjustment to reflect accrued liabilities for transaction costs directly attributable to the arrangement deemed to be incurred by TransGlobe of $4,418 thousand as though the acquisition occurred on June 30, 2022.

(D)	Gain on acquisition results from the difference between the purchase consideration and the fair value of the assets acquired less the fair value of liabilities assumed.

(b)	Other Impacts of the arrangement on the unaudited pro forma combined balance sheet as of June 30, 2022

(i)	Adjustment to reflect the recognition of transaction costs directly attributable to the arrangement deemed to be incurred by VAALCO of $10,672 thousand as though the acquisition occurred as of June 30, 2022.

(ii)	Adjustment to remove TransGlobe’s pre-acquisition equity balances on consolidation.

4. Impact of the Arrangement on the unaudited pro forma combined statements of operations for the six months ended June 30, 2022, and for the year ended December 31, 2021

(a)	Depreciation, depletion and amortization

Represents the incremental depreciation, depletion and amortization related to the assets acquired in the arrangement, which is based on the preliminary purchase price allocation. Depletion of petroleum and natural gas assets was calculated using the unit-of-production method, adjusted to reflect a) the fair value of TransGlobe’s Crude oil and natural gas properties, equipment and other – successful efforts method, net as of the arrangement date as though the arrangement occurred on January 1, 2021; and b) estimates of TransGlobe’s proved reserves following the methodology required by SEC regulations.

TABLE OF CONTENTS

(b)	Income Tax

There is no impact of the arrangement on taxes. TransGlobe recorded a full valuation allowance on its deferred tax assets as of December 31, 2021, and June 30, 2022. The position on the valuation allowance has not changed resulting from the arrangement.

(c)	Transaction costs

Adjustment to reflect the recognition of transaction costs directly attributable to the arrangement deemed to be incurred by VAALCO of $10,672 thousand and TransGlobe of $4,418 thousand as though the acquisition occurred on January 1, 2021.

Transaction costs expensed by TransGlobe of $1,582 thousand in the statement of operations for the six months ended June 30, 2022, has been reclassified from General and administrative expense to Other (expense) income, net in the unaudited pro forma statement of operations for the six months ended June 30, 2022.

(d)	Stock-based compensation and severance expense

(i)

Adjustment to reflect the recognition of pre-combination stock-based compensation expense under U.S. GAAP by TransGlobe upon the acceleration of vesting on change of control for TransGlobe’s stock options, RSUs and PSUs under the terms of the original awards and the arrangement agreement as though the acquisition occurred on January 1, 2021. Such awards will be cash settled by TransGlobe prior to the closing of the arrangement.

(ii)	Adjustment to reflect the recognition of severance expense and the corresponding adjustment to cash and cash equivalent in relation to payment on termination of certain executives of TransGlobe pursuant to the terms of their executive employment arrangement.

(e)	Earnings per Share

The table below represents the calculation of the weighted average shares outstanding and earnings per share included in the unaudited pro forma combined statement of operations for the six months ended June 30, 2022. As the arrangement is being reflected in the unaudited pro forma combined statement of operations for the six months ended June 30, 2022, as if it had occurred on January 1, 2021, the calculation of weighted average shares outstanding for basic and diluted earnings per share assumes that the shares issuable relating to the arrangement have been outstanding for the entire year.

5. Supplemental Pro Forma Information on Crude Oil and Natural Gas Producing Activities

The following tables present the estimated pro forma combined net proved developed and undeveloped crude oil, natural gas and natural gas liquids (“NGLs”) prepared as of December 31, 2021, along with a summary of changes in the quantities of net remaining proved reserves during the year ended December 31, 2021. The combined standardized measure of discounted future net cash flows relating to proved reserves as of December 31, 2021, are also presented.

This pro forma combined reserve, production and standardized measure information gives effect to the arrangement as if it had been completed on January 1, 2021. The historical proved reserves information presented below represent the respective estimates made as of December 31, 2021, by VAALCO and TransGlobe while they were separate companies. These estimates have not been updated for changes in development plans or other factors, which have occurred or may occur subsequent to December 31, 2021, or subsequent to the completion of the arrangement. This pro forma information has been prepared for illustrative purposes and is not intended to be a projection of future results of the combined business. With respect to the disclosures below, the amounts were determined by referencing the “Supplemental Information on Crude Oil and Natural Gas Producing Activities (Unaudited)” reported in VAALCO’s Annual Report on Form 10-K for the year ended December 31, 2021, and the “Statement of Reserves Data and Other Oil and Gas Information” reported in TransGlobe’s Annual Report on Form 40-F for the year ended December 31, 2021; an explanation of the underlying methodology applied, as required by SEC regulations, can be found therein.

TransGlobe has historically prepared the reserves data disclosed in its Annual Report on Form 40-F in accordance with the standards contained in the Canadian Oil and Gas Evaluation Handbook maintained by the Society of Petroleum Evaluation Engineers (Calgary Chapter) (the “COGE Handbook”) and the reserves definitions contained in National Instrument 51-101 – Standards for Disclosure of Oil and Gas Activities (“NI 51-101”) and the COGE Handbook. In order to align TransGlobe’s presentation to that of VAALCO, TransGlobe’s reserves data presented herein has been prepared following the methodology required by SEC regulations.

UNAUDITED PRO FORMA PER SHARE DATA

The following table presents, as of the dates and for the periods indicated, selected historical Unaudited Pro Forma Combined Financial Information per share of VAALCO common stock and per TransGlobe common share. You should read this information in conjunction with, and the information is qualified in its entirety by, the consolidated financial statements of VAALCO and notes thereto incorporated by reference into this proxy statement, and the consolidated financial statements of TransGlobe and notes thereto incorporated by reference into this proxy statement. See the “Where You Can Find More Information” section of this proxy statement.

The following pro forma information has been prepared in accordance with the rules and regulations of the SEC and accordingly includes the effects of acquisition accounting. It does not reflect cost savings, synergies or certain other adjustments that may result from the arrangement. This information is presented for illustrative purposes only. You should not rely on the pro forma combined or equivalent pro forma amounts as they are not necessarily indicative of the operating results or financial position that would have occurred if the arrangement had been completed as of the dates indicated, nor are they necessarily indicative of the future operating results or financial position of the combined company. The pro forma information, although helpful in illustrating the financial characteristics of the combined company under one set of assumptions, does not reflect the benefits of expected cost savings, opportunities to earn additional revenue, the impact of restructuring and arrangement-related costs, or other factors that may result as a consequence of the arrangement and, accordingly, does not attempt to predict or suggest future results.

The following table assumes the issuance of approximately 49.315 million shares of VAALCO common stock in connection with the arrangement, which is the number of shares issuable by VAALCO in connection with the arrangement assuming the arrangement occurred on January 1, 2021 and based on the number of outstanding TransGlobe common shares at that time. As discussed in this proxy statement, the actual number of shares of VAALCO common stock issuable under the arrangement will be adjusted based on the number of TransGlobe common shares outstanding at the completion of the arrangement. The pro forma data in the table assumes that the arrangement occurred on January 1, 2021 for income statement purposes and on June 30, 2022 for balance sheet purposes, and that the arrangement is accounted for as a business combination.

RISK FACTORS

Before you make a decision on the amendment proposal or the share issuance proposal presented, you should carefully consider specific risks set forth herein, as well as in other documents referred to elsewhere, or incorporated by reference, in this proxy statement, in addition to the risks and uncertainties discussed in the “Cautionary Statement Regarding Forward-Looking Statements” section of this proxy statement. As a stockholder of VAALCO following the consummation of the arrangement, you will be subject to all risks inherent in the business of VAALCO in addition to the risks relating to TransGlobe. The market value of your shares will reflect the performance of the business relative to, among other things, that of the competitors of VAALCO and general economic, market and industry conditions. The value of your investment may increase or may decline and could result in a loss. For information regarding the documents incorporated by reference into this proxy statement, see the “Where You Can Find More Information” section of this proxy statement.

Risks Relating to the Arrangement

The arrangement is subject to satisfaction or waiver of several conditions.

The arrangement is conditional upon, among other things, approval of the issuance of the VAALCO common stock to TransGlobe shareholders in exchange for their TransGlobe common shares pursuant to the arrangement agreement and approval of the amendment proposal by VAALCO stockholders, approval of the TransGlobe resolution by TransGlobe shareholders, and to the extent required or necessary, the approval or consent of, or waiver or non-exercise of any material termination, pre-emption or similar rights by, any governmental entity in, or in respect of the interests held by TransGlobe in, Canada or Egypt. There can be no assurance that any or all of such required approvals, if any, will be obtained.

TransGlobe’s Concession Agreements in Egypt contain assignment provisions and, if such assignment provisions were triggered by the arrangement, it could adversely affect the ability to consummate the arrangement or the benefits anticipated to be realized from the arrangement in a material manner.

Under the arrangement agreement, it is a condition precedent to the obligation of VAALCO and AcquireCo to complete the arrangement that, to the extent required or necessary in connection with the consummation of the transactions contemplated therein: (i) the approval or consent of, or waiver or non-exercise of any material termination, pre-emption or similar rights by, any governmental entity in, or in respect of the interests held by TransGlobe in, Canada and Egypt, be given on terms or subject to conditions in each case which are satisfactory to VAALCO; and (ii) no actions or inactions have been taken which are likely to result in the withdrawal, cancellation, termination or modification of any license or permit held by TransGlobe or any of its subsidiaries in respect of the interests held by TransGlobe in Canada and Egypt which is necessary for the proper carrying on of its business.

The TransGlobe Egyptian Parties, are parties to two Concession Agreements with the EGPC and the Egyptian Government that provide exclusive rights to explore for and develop oil and gas in the South Ghazalat Area Western Desert and the merged development areas of West Bakr, West Gharib and Northwest Gharib Onshore. The Concession Agreements contain the Assignment Provisions, which provide that the TransGlobe Egyptian Parties may not assign any of their rights, privileges, duties or obligations under the Concession Agreements, directly or indirectly, without the written consent of the Egyptian Government. In addition, if the Assignment Provisions are triggered, (i) the EGPC has the right to acquire the interest intended to be assigned on the same conditions, if it elects to do so within 90 days of receiving the final conditions (including the value of each assignment); and (ii) the TransGlobe Egyptian Parties would be required to pay a non-recoverable assignment fee to the EGPC in an amount equal to 10% of the value of each assignment upon the Egyptian Government’s approval of any assignment.

Neither VAALCO nor TransGlobe believes that the arrangement triggers the Assignment Provisions, and TransGlobe has made representations to that effect in the arrangement agreement.

Following announcement of the arrangement, the EGPC delivered correspondences to each of VAALCO and TransGlobe requesting data and documents relating to the arrangement, the value of the deal and TransGlobe’s share in the relevant Egyptian assets. VAALCO and TransGlobe have engaged, and are continuing to engage, in discussions with the office of the Minister of Petroleum and the EGPC, for the purpose of clarifying that the arrangement does not, and is not deemed to, trigger the Assignment Provisions in the Concession Agreements.

If the arrangement did trigger the Assignment Provisions, consummation of the arrangement would require the written approval of the Egyptian Government, which could result in a failure of the condition precedent to the

TABLE OF CONTENTS

obligation of VAALCO and AcquireCo to complete the arrangement described in the first paragraph of this risk factor or could delay the consummation of the arrangement. In addition, payment of any assignment fees by any of the TransGlobe Egyptian Parties under the Concession Agreements, either before or after consummation of the arrangement, could have an adverse effect on the value of the assets VAALCO would acquire as a result of the arrangement and could adversely affect the results of operations or financial condition of VAALCO following consummation of the arrangement, in each case, in a material manner. Further, although neither VAALCO nor TransGlobe is aware of any reported cases of a concession being terminated on such grounds, it is possible that the Egyptian Government could seek to terminate the Concession Agreements for breach of the Assignment Provisions.

The arrangement agreement may be terminated in certain circumstances.

Each of VAALCO and TransGlobe has the right to terminate the arrangement agreement in certain circumstances. Failure to complete the arrangement could negatively impact the trading price of VAALCO common stock or otherwise adversely affect VAALCO’s business.

We may be required to pay a termination fee or an expense reimbursement.

If the arrangement agreement is terminated (i) by TransGlobe as a result of a change in recommendation by us at any time prior to the special meeting; (ii) by either party as a result of a failure to obtain approval of the amendment proposal and the share issuance proposal following a change in recommendation by us; or (iii) (A) by either party due to the effective date of the arrangement not occurring prior to the outside date or a failure to obtain approval of the amendment proposal and the share issuance proposal; or (B) by TransGlobe as a result of our breach of any representation or warranty or our failure to perform any covenant or agreement made by us in the arrangement agreement and such breach or failure would cause certain of the conditions in the arrangement agreement to not be satisfied, but in each case, only if prior to termination there is an acquisition proposal (for the purposes of the discussion on termination fees, a reference to “20 per cent” in the definition of “acquisition proposal” is deemed to be a reference to “50 per cent”) for us announced and within 12 months of termination we enter into an agreement or consummate an acquisition proposal, we will be required to pay a termination fee of $9.15 million to TransGlobe in connection with the termination of the arrangement agreement.

We may also be required to reimburse TransGlobe’s out-of-pocket expenses in an amount up to $2.00 million if the arrangement agreement is terminated (x) by either party as a result of a failure to obtain approval of the amendment proposal and the share issuance proposal; or (y) by TransGlobe as a result of our breach of any representation or warranty or our failure to perform any covenant or agreement made by us in the arrangement agreement and such breach or failure would cause certain of the conditions in the arrangement agreement to not be satisfied.

If the termination fee or expense reimbursement is ultimately required to be paid to TransGlobe, the payment of such amounts may have an adverse impact on our financial results.

If the arrangement is not consummated by the outside date, either TransGlobe or VAALCO may choose not to proceed with the arrangement.

Either TransGlobe or VAALCO may terminate the arrangement agreement if the arrangement has not been completed by the outside date and the parties do not mutually agree to extend the arrangement agreement. See “The Arrangement Agreement and the Plan of Arrangement—Termination of the Arrangement Agreement” section of this proxy statement.

The issuance of a significant number of shares of VAALCO common stock and a resulting possible increase in the number of sellers could adversely affect the market price of shares of VAALCO common stock after completion of the arrangement.

On completion of the arrangement, a significant number of additional shares of VAALCO common stock will be issued and available for trading in the public market. The increase in the number of shares of VAALCO common stock may lead to sales of such shares or the perception that such sales may occur, either of which may adversely affect the market for, and the market price of, shares of VAALCO common stock.

VAALCO does not currently control TransGlobe and its subsidiaries.

VAALCO will not control TransGlobe and its subsidiaries until completion of the arrangement and the business and results of operations of TransGlobe may be adversely affected by events that are outside of VAALCO’s control during the intervening period. The performance of TransGlobe may be influenced by, among other factors, economic

TABLE OF CONTENTS

downturns, changes in commodity prices, political instability in the countries in which TransGlobe operates, changes in applicable laws, expropriation, increased environmental regulation, volatility in the financial markets, unfavorable regulatory decisions, litigation, rising costs, civic and labor unrest, disagreements with joint venture partners, delays in ongoing exploration and development projects and other factors beyond VAALCO’s control. As a result of any one or more of these factors, among others, the operations and financial performance of TransGlobe may be negatively affected, which may adversely affect the future financial results of the combined company.

We will incur substantial transaction fees and costs in connection with the arrangement.

We have incurred and expect to incur additional material non-recurring expenses in connection with the arrangement (regardless of whether the transactions contemplated by the arrangement agreement are consummated or not), including, among others, costs relating to obtaining required stockholder approvals and Court approval. Additional unanticipated costs may be incurred in the course of coordinating the businesses of the combined company after completion of the arrangement. If the arrangement is not consummated, we will be required to pay certain costs relating to the arrangement incurred prior to the date the arrangement is abandoned, such as legal, accounting, financial advisory, proxy solicitation and printing fees. Such costs may be significant and could have an adverse effect on our future results of operations, cash flows and financial condition.

VAALCO and TransGlobe may be the targets of legal claims, securities class actions, derivative lawsuits and other claims and negative publicity related to the arrangement.

VAALCO and TransGlobe may be the target of securities class actions and derivative lawsuits which could result in substantial costs and may delay or prevent the arrangement from being completed. Securities class action lawsuits and derivative lawsuits are often brought against companies that have entered into an agreement to acquire a public company or to be acquired. Third parties may also attempt to bring claims against VAALCO or TransGlobe seeking to restrain the arrangement or seeking monetary compensation or other remedies. Even if the lawsuits are without merit, defending against these claims can result in substantial costs and divert management time and resources. Additionally, if a plaintiff is successful in obtaining an injunction prohibiting consummation of the arrangement, then that injunction may delay or prevent the arrangement from being completed.

In addition, political and public attitudes towards the arrangement could result in negative press coverage and other adverse public statements affecting VAALCO and TransGlobe. Adverse press coverage and other adverse statements could lead to investigations by regulators, legislators and law enforcement officials or in legal claims or otherwise negatively impact the ability of the combined company to take advantage of various business and market opportunities. The direct and indirect effects of negative publicity, and the demands of responding to and addressing it, may have a material adverse effect on the combined company’s business, financial condition and results of operations.

The exchange ratio will not be adjusted in the event of any change in either VAALCO’s or TransGlobe’s share price.

Upon completion of the arrangement, each TransGlobe common share (other than TransGlobe common shares held by dissenting TransGlobe shareholders) will be converted into the right to receive 0.6727 of a share of VAALCO common stock, subject to adjustment (if any) pursuant to the arrangement agreement. This exchange ratio was fixed in the arrangement agreement and will not be adjusted to reflect changes in the market price of either TransGlobe common shares or VAALCO common stock before the arrangement is completed. Stock price changes may result from a variety of factors (many of which are beyond VAALCO’s and TransGlobe’s control), including the following:

•	changes in VAALCO’s and TransGlobe’s respective businesses, operations and prospects;

•	investor behavior and strategies, including market assessments of the likelihood that the arrangement will be completed, including related considerations regarding court approval and regulatory clearance, if any, of the arrangement;

•	interest rates, general market and economic conditions and other factors generally affecting the price of VAALCO’s and TransGlobe’s shares; and

•	foreign, federal, state, provincial and local legislation, governmental regulation and legal developments in the businesses in which VAALCO and TransGlobe operate.

TABLE OF CONTENTS

The price of VAALCO common stock at the completion of the arrangement will vary from its price on the date the arrangement agreement was executed, the date of this proxy statement and the date of the special meeting. As a result, the market value represented by the exchange ratio will also vary. For example, based on the range of closing prices of VAALCO common stock during the period from July 13, 2022, the last trading day before public announcement of the arrangement, through August 24, 2022, the latest practicable date before the date of this proxy statement, the exchange ratio represented a market value ranging from a low of $3.03 to a high of $4.30 for each TransGlobe common share.

VAALCO stockholders will experience substantial dilution of their ownership percentage and voting power as a result of the stock issuance.

In connection with the arrangement, VAALCO is expected to issue approximately 49.3 million shares of its common stock to TransGlobe shareholders. Immediately following the completion of the arrangement, former TransGlobe shareholders will own collectively approximately 45.5% of the total number of shares of the combined company’s outstanding common stock and the existing stockholders of VAALCO will own approximately 54.5% of the combined company, calculated based on VAALCO’s vested and outstanding shares and TransGlobe’s outstanding shares, each as of the date of the arrangement agreement. Accordingly, the issuance of VAALCO common stock to TransGlobe shareholders will have the effect of reducing the percentage of equity and voting interest held by each of VAALCO’s existing stockholders. Consequently, VAALCO stockholders as a group will have less influence over the management and policies of the combined company than they currently exercise.

We currently intend to pay dividends on, and effectuate share buybacks with respect to, VAALCO common stock; however, our ability to take these actions in the future may be limited and no assurance can be given that we will be able to pay dividends to VAALCO stockholders or effectuate share buybacks in the future at indicated levels or at all.

On November 3, 2021, VAALCO announced that the VAALCO board of directors adopted a quarterly cash dividend policy of an expected $0.0325 per share of VAALCO common stock commencing in the first quarter of 2022. On March 18, 2022 and June 24, 2022, we paid a quarterly cash dividend of $0.0325 per share of VAALCO common stock to VAALCO stockholders of record at the close of business on February 18, 2022 and May 25, 2022, respectively. On August 5, 2022, VAALCO board of directors declared a quarterly cash dividend of $0.0325 per share of VAALCO common stock, which is payable on September 23, 2022 to stockholders of record at the close of business on August 24, 2022. In connection with the announcement of the arrangement, VAALCO announced that following consummation it would seek to have an annualized dividend target of $28 million, or approximately $0.25 per share (calculated based on VAALCO’s vested and outstanding shares and TransGlobe’s outstanding shares, each as of the date of the arrangement agreement), with payments to be made quarterly. VAALCO has also announced its intention to effectuate, and the VAALCO board of directors has approved, share buybacks in an aggregate amount of up to $30 million, or up to approximately $0.27 per share equivalent (calculated based on VAALCO’s vested and outstanding shares and TransGlobe’s outstanding shares, each as of the date of the arrangement agreement), subject to completion of the arrangement. To the extent VAALCO has adequate cash on hand and cash flows from operations, we will consider taking these actions in the future. Payment of future dividends and effectuation of share buybacks, if any, and the establishment of future record and payment dates will be at the discretion of the VAALCO board of directors after taking into account various factors, including current financial condition, the tax impact of repatriating cash, operating results and current and anticipated cash needs. As a result, no assurance can be given that we will be able to continue to pay dividends to our stockholders or the terms on which we will effectuate share buybacks in the future or that the level of any future dividends will achieve a market yield or increase or even be maintained over time, any of which could materially and adversely affect the market price of VAALCO common stock.

The arrangement could affect the price of VAALCO common stock as a result of market response to the arrangement, significant delays in the consummation of the arrangement or the termination of the arrangement agreement.

The market price of VAALCO common stock may vary significantly from the price on the date of the arrangement agreement. Negative market response to the arrangement or any significant delays in the consummation of the arrangement could negatively affect our stock price. In addition, there can be no assurance that the conditions to the consummation of the arrangement will be satisfied in a timely manner or at all. If the arrangement is not consummated or is delayed, the market price of VAALCO common stock may decline significantly, particularly to the extent the market price reflects a market assumption that the arrangement will be consummated or will be consummated in a particular timeframe.

TABLE OF CONTENTS

Stock price changes may result from a variety of factors that are beyond our control, including:

•	market reaction to the announcement of the arrangement and market assessment of the likelihood of the arrangement being consummated;

•	changes in the respective businesses, operations or prospects of VAALCO or TransGlobe, including their respective ability to meet earnings estimates;

•	governmental or litigation developments or regulatory considerations affecting VAALCO or TransGlobe or the oil and gas industry;

•	general business, market, industry or economic conditions;

•	the worldwide supply/demand balance for oil and gas and the prevailing commodity price environment; and

•	other factors beyond our control, including those described elsewhere in, or incorporated by reference into, this “Risk Factors” section.

Risk Factors on Completion of the Arrangement

Significant demands will be placed on the combined company as a result of the arrangement.

As a result of the pursuit and completion of the arrangement, significant demands will be placed on the managerial, operational and financial personnel and systems of the combined company. We cannot provide any assurance that management of VAALCO and the operations teams of VAALCO and TransGlobe will be adequate to support the expansion of operations and associated increased costs and complexity following and resulting from the consummation of the arrangement. The future operating results of the combined company will be affected by the ability of its officers and key employees to manage changing business conditions, integrate the acquisition of TransGlobe and implement a new business strategy.

We may not realize the anticipated benefits of the arrangement and the integration of TransGlobe may not occur as planned.

The arrangement has been agreed with the expectation that its completion will result in accretive reserves and expected production amounts as well as enhanced growth capital markets opportunities for the combined company. These anticipated benefits will depend in part on whether TransGlobe’s and VAALCO’s operations can be integrated in an efficient and effective manner. A significant number of operational and strategic decisions and certain staffing decisions with respect to integration of the two companies have not yet been made. These decisions and the integration of the two companies will present challenges to management, including the integration of systems and personnel of the two companies which may be geographically separated, anticipated and unanticipated liabilities, unanticipated costs (including substantial capital expenditures required by the integration) and the loss of key employees. In particular, following a transition period of up to six months following consummation of the arrangement, VAALCO expects the departure of TransGlobe’s President and Chief Executive Officer, Vice President, Finance, Chief Financial Officer and Corporate Secretary and Vice President and Chief Operating Officer. These departures may result in a loss of institutional knowledge concerning TransGlobe’s operations and could delay the achievement of the combined company’s strategic objectives. In addition, there may be potential unknown liabilities of TransGlobe that may prevent the combined company from fully realizing the anticipated benefits of the arrangement.

The performance of the combined company’s operations after completion of the arrangement could be adversely affected if, among other things, the combined company is not able to achieve the anticipated benefits expected to be realized in entering the arrangement, or retain key employees to assist in the integration and operation of TransGlobe and VAALCO. In particular, the combined company may not be able to realize the anticipated strategic benefits and synergies from the arrangement. VAALCO believes that the combination of the companies will provide a number of operational and financial benefits. However, achieving these goals assumes, among other things, the realization of the targeted cost synergies expected from the arrangement. The consummation of the arrangement may pose special risks, including one-time write-offs, restructuring charges and unanticipated costs. In addition, the integration process could result in diversion of the attention of management and disruption of existing relationships with suppliers, employees, customers and other constituencies of each company. Although VAALCO and its advisors have conducted due diligence on the operations of TransGlobe, there can be no guarantee that VAALCO is aware of any and all liabilities of TransGlobe.

TABLE OF CONTENTS

In addition, management of VAALCO has assumed that VAALCO will be able to elect to treat the arrangement as an asset acquisition under Section 338(g) of the Internal Revenue Code of 1986, as amended (the “Code”). This election may be unavailable if existing TransGlobe shareholders own shares of VAALCO common stock in an amount that prevents the arrangement from being a “qualified stock purchase” (within the meaning of Section 338(d)(3) of the Code). A determination of the common ownership of VAALCO and TransGlobe is not possible until the closing of the arrangement and may still be subject to uncertainty following the closing. If an election under Section 338(g) of the Code is unavailable, the integration of TransGlobe may give rise to additional tax costs and the actual combined performance of VAALCO and TransGlobe following the arrangement may differ materially from the assumptions of VAALCO’s management.

As a result of these and other factors, it is possible that certain benefits expected from the combination of TransGlobe and VAALCO may not be realized.

The combined company may not generate sufficient cash to satisfy TransGlobe’s payment obligations under the Merged Concession Agreement or be able to collect some or all of TransGlobe’s receivables from the EGPC, which could negatively affect the combined company’s operating results and financial condition

On January 19, 2022, subsidiaries of TransGlobe executed an agreement with the EGPC (the “Merged Concession Agreement”) to update and merge TransGlobe’s three Egyptian concessions in West Bakr, West Gharib and NW Gharib (the “Merged Concession”). The Merged Concession Agreement was signed by its parties on January 19, 2022 with an effective date of February 1, 2020 (the “Merged Concession Effective Date”). As part of the conditions precedent to the signing of the Merged Concession Agreement by the Minister of Petroleum & Mineral Resources on behalf of the Egyptian Government, TransGlobe remitted the initial modernization payment of $15.0 million and signature bonus of $1.0 million. In accordance with the Merged Concession Agreement, TransGlobe made another modernization payment to the EGPC in the amount of $10.0 million on February 1, 2022. The modernization payments under the Merged Concession Agreement total $65.0 million and are payable over six years from the Merged Concession Effective Date. TransGlobe will be required to pay an additional $10.0 million on February 1^st for each of the next four years. In addition, TransGlobe has committed to spending a minimum of $50.0 million over each five-year period for the 15 years of the primary term (total $150.0 million). TransGlobe’s ability to make scheduled payments arising from the Merged Concession Agreement will depend on its financial condition and operating performance, which would be subject to then prevailing economic, industry and competitive conditions and to certain financial, business, legislative, regulatory and other factors beyond its control, including those discussed elsewhere in this “Risk Factors” section and in the documents incorporated by reference into this proxy statement. TransGlobe may be unable to maintain a level of cash flow sufficient to permit it to satisfy the payment obligations under the Merged Concession Agreement. If TransGlobe is unable to satisfy its obligations, it is possible that the EGPC could seek to terminate the Merged Concession Agreement, which would negatively affect the combined company’s operating results and financial condition.

In addition, upon execution of the Merged Concession Agreement, there was a Merged Concession Effective Date adjustment of funds owed to TransGlobe for the difference between the commercial terms in the Concession Agreement and the Merged Concession Agreement applicable to the Eastern Desert production from the Merged Concession Effective Date. The quantum of this adjustment is currently being finalized with the EGPC and could result in a range of outcomes based on the final price per barrel negotiated. TransGlobe has recognized a receivable of $67.5 million as of June 30, 2022, which represents the amount expected to be received from the EGPC based on historical realized prices. If the EGPC’s financial position becomes impaired or it disputes or if the EGPC refuses to pay some or all of the said amount, TransGlobe’s ability to fully collect such receivable from the EGPC could be impaired, which could negatively affect the combined company’s operating results and financial condition.

Inflation could adversely impact the combined company’s ability to control its costs, including its operating expenses and capital costs.

Although inflation has been relatively low in recent years, it rose significantly in the second half of 2021 and the first half of 2022. In addition, global and industry-wide supply chain disruptions have resulted in shortages in labor, materials and services. Such shortages have resulted in inflationary cost increases for labor, materials and services and could continue to cause costs to increase, as well as a scarcity of certain products and raw materials. To the extent elevated inflation remains, the combined company may experience further cost increases for its operations, including oilfield services and equipment as increasing prices of oil, natural gas and natural gas liquids increased drilling activity in its areas of operations, as well as increased labor costs. An increase in the prices of oil, natural

TABLE OF CONTENTS

gas and natural gas liquids may cause the costs of materials and services we use to rise. We cannot predict any future trends in the rate of inflation, and a significant increase in inflation, to the extent we are unable to recover higher costs through higher commodity prices and revenues, could negatively impact our business, financial condition and results of operation.

TransGlobe’s public filings are subject to Canadian disclosure standards, which differ from SEC disclosure requirements.

VAALCO’s reserve estimates have been prepared in accordance with United States Financial Accounting Standards Board’s (“FASB”) ASC Topic 932 – Extractive Activities – Oil and Natural Gas under U.S. GAAP and subpart 1200 of Regulation S-K promulgated by the SEC (the “U.S. Standards”). VAALCO has not been involved in the preparation of TransGlobe’s historical oil and natural gas reserves estimates. TransGlobe’s historical oil and natural gas reserves estimates were prepared in accordance with the standards set forth in the COGE Handbook and the reserves definitions contained in NI 51-101 and the COGE Handbook, which differ from the requirements of United States securities laws. In addition to being a reporting issuer in all provinces of Canada, TransGlobe is a registrant with the SEC but is permitted to present disclosure of its reserves information in accordance with the standards set out in the COGE Handbook and the reserves definitions contained in NI 51-101 and the COGE Handbook.

Estimates of reserves and future net revenue made in accordance with NI 51-101 will differ from corresponding U.S. GAAP standardized measure prepared in accordance with U.S. Standards and those differences may be material. For example, the U.S. standards require United States oil and gas reporting companies, in their filings with the SEC, to disclose only proved reserves after the deduction of royalties and production due to others but permits the optional disclosure of probable and possible reserves in accordance with SEC’s definitions. Additionally, the COGE Handbook and NI 51-101 require disclosure of reserves and related future net revenue estimates based on forecast prices and costs, whereas the U.S. Standards require that reserves and related future net revenue be estimated using average prices for the previous 12 months and that the standardized measure reflect discounted future net income taxes related to VAALCO’s operations. In addition, the COGE Handbook and NI 51-101 permit the presentation of reserves estimates on a “company gross” basis, representing TransGlobe’s working interest share before deduction of royalties, whereas the U.S. Standards require the presentation of net reserve estimates after the deduction of royalties and similar payments. There are also differences in the technical reserves estimation standards applicable under NI 51-101 and, pursuant thereto, the COGE Handbook, and those applicable under the U.S. Standards. NI 51-101 requires that proved undeveloped reserves be reviewed annually for retention or reclassification if development has not proceeded as previously planned, while the U.S. Standards specify a five-year limit after initial booking for the development of proved undeveloped reserves. Finally, the SEC prohibits disclosure of oil and gas resources in SEC filings, including contingent resources, whereas Canadian securities regulatory authorities allow disclosure of oil and gas resources. Resources are different than, and should not be construed as, reserves. The foregoing is not an exhaustive summary of Canadian or U.S. reserves reporting requirements.

The VAALCO board of directors and VAALCO’s financial advisor considered financial projections in connection with the arrangement. VAALCO management has also presented certain hypothetical Illustrative Scenarios. Actual performance of VAALCO and TransGlobe may differ materially from these projections and Illustrative Scenarios.

The VAALCO board of directors considered, among other things, certain projections with respect to each of VAALCO (the “VAALCO projections”), TransGlobe (the “TransGlobe projections” and, together with the VAALCO projections, the “projections”) prepared by VAALCO management or TransGlobe management and adjusted by VAALCO management. The projections were also provided to Stifel, VAALCO’s financial advisor, for its use in advising VAALCO and reliance in connection with its financial analyses and opinion as described in the “The Arrangement— Opinion of Financial Advisor to VAALCO” section of this proxy statement. On August 3, 2022, VAALCO disclosed that its South Tchibala 1HB0ST well had performed below expectations and revised its production guidance for the full year 2022 from between 9,500 and 10,500 barrels of oil equivalent per day to between 9,000 and 9,500 barrels of oil equivalent per day. Following this disclosure, on August 8, 2022, VAALCO management prepared certain hypothetical illustrative scenarios for the years ended 2022 and 2023 based upon various oil prices and taking into account its new production guidance and $4 million in cost synergies (the “Illustrative Scenarios”). Information about the revised production guidance for VAALCO’s South Tchibala 1HB0ST well and the Illustrative Scenarios were unavailable to, or not prepared by, VAALCO until August 2022 and accordingly were not part of the projections provided to Stifel, VAALCO’s financial advisor, for use in connection with its opinion delivered to the VAALCO board of directors on July 13, 2022.

TABLE OF CONTENTS

All such projections and Illustrative Scenarios were based on assumptions and information available at the respective times such projections and Illustrative Scenarios were prepared. VAALCO and its advisors do not know whether the assumptions made will be realized. Such information can be adversely affected by known or unknown risks and uncertainties, many of which are beyond VAALCO’s and TransGlobe’s control. Further, financial forecasts of this type are based on estimates and assumptions that are inherently subject to risks and other factors such as company performance, industry performance, general business, economic, regulatory, market and financial conditions, as well as changes to the business, financial condition or results of operations of VAALCO and TransGlobe, including the factors described in the “Risk Factors” and “Cautionary Statement Regarding Forward-Looking Statements” sections of this proxy statement, which factors and changes may impact such forecasts or the underlying assumptions. As a result of these contingencies, there can be no assurance that the financial and other projections or the Illustrative Scenarios will be realized or that actual results will not be significantly higher or lower than projected. In view of these uncertainties, the inclusion of the projections and Illustrative Scenarios in this proxy statement should not be regarded as an indication that VAALCO, its board of directors, or any of its advisors or any other recipient of this information considered, or now considers, it to be an assurance of the achievement of future results.

The projections were prepared for internal use and to, among other things, assist VAALCO and its advisors in evaluating the transaction. The projections were not prepared with a view toward public disclosure. Neither the projections nor the Illustrative Scenarios were prepared in accordance with U.S. GAAP, published guidelines of the SEC or the guidelines established by the American Institute of Certified Public Accountants for preparation and presentation of prospective financial information. BDO USA, LLP, VAALCO’s independent registered public accounting firm, has not examined, compiled or performed any procedures with respect to the projections or the Illustrative Scenarios.

In addition, management of VAALCO has assumed that VAALCO will be able to elect to treat the arrangement as an asset acquisition under Section 338(g) of the Code. This election may be unavailable if existing TransGlobe stockholders own shares of VAALCO common stock in an amount that prevents the arrangement from being a “qualified stock purchase” (within the meaning of Section 338(d)(3) of the Code). A determination of the common ownership of VAALCO and TransGlobe is not possible until the closing of the arrangement and may still be subject to uncertainty following the closing. If an election under Section 338(g) of the Code is unavailable, the integration of TransGlobe may give rise to additional tax costs and the actual combined performance of VAALCO and TransGlobe following the arrangement may differ materially from management’s assumptions.

Finally, the projections and Illustrative Scenarios have not been updated or revised to reflect information or results after the respective dates that such projections and Illustrative Scenarios were prepared. Except as required by applicable securities laws, VAALCO does not intend to update or otherwise revise the projections or the Illustrative Scenarios to reflect circumstances existing after the respective dates when made or to reflect the occurrence of future events, even in the event that any or all of the assumptions are shown to be in error.

The Unaudited Pro Forma Combined Financial Information of VAALCO and TransGlobe is presented for illustrative purposes only and may not be indicative of the results of operations or financial condition of the combined company following the arrangement.

The Unaudited Pro Forma Combined Financial Information included in this proxy statement are presented for illustrative purposes only to show the effect of the arrangement, and should not be considered to be an indication of the financial condition or results of operations of the combined company following the arrangement. For example, the pro forma combined financial information has been prepared using the consolidated historical financial statements of VAALCO and of TransGlobe and do not represent a financial forecast or projection. In addition, the pro forma combined financial information included in this proxy statement are based in part on certain assumptions regarding the arrangement. In addition, certain adjustments and assumptions have been made regarding the combined company after giving effect to the arrangement. The information upon which these adjustments and assumptions have been made is preliminary, and these types of adjustments and assumptions are difficult to make with complete accuracy, and other factors may affect the combined company’s results of operations or financial condition following the arrangement.

In preparing the pro forma combined financial information contained in this proxy statement, we have given effect to, among other things, the completion of the arrangement and the issuance of the consideration shares. The Unaudited Pro Forma Combined Financial Information does not reflect all of the costs that are expected to be incurred by us in connection with the arrangement. For example, the impact of any incremental costs incurred in

TABLE OF CONTENTS

integrating VAALCO and TransGlobe is not reflected in the pro forma combined financial information. See the notes to the unaudited pro forma combined financial statements of VAALCO and TransGlobe included in the “Unaudited Pro Forma Combined Financial Information” section of this proxy statement.

Accordingly, the historical and pro forma combined financial information included in, or incorporated by reference into, this proxy statement does not necessarily represent the combined company’s results of operations and financial condition had VAALCO and TransGlobe operated as a combined entity during the periods presented, or of the combined company’s results of operations and financial condition following the arrangement.

The actual financial condition and results of operations of the combined company following the arrangement may not be consistent with, or evident from, these pro forma financial statements. In addition, the assumptions used in preparing the pro forma financial information may not prove to be accurate, and other factors may affect the combined company’s financial condition or results of operations following the arrangement. Any potential decline in the combined company’s financial condition or results of operations may cause a significant decrease in our stock price.

The opinion obtained by VAALCO from its financial advisor as to the fairness of the consideration, from a financial point of view, to VAALCO only speaks as of the date of such opinion, and will not be updated to reflect changes in circumstances from the signing of the arrangement agreement through the closing of the arrangement.

Stifel, VAALCO’s financial advisor, presented its financial analysis to the VAALCO board of directors and also delivered its oral opinion, which was subsequently confirmed in writing, that as of the date of and based on the assumptions and factors described in the written opinion, the consideration to be paid by VAALCO to the TransGlobe shareholders pursuant to the arrangement was fair, from a financial point of view, to VAALCO. However, VAALCO has not obtained an updated opinion from Stifel as of the date of this proxy statement, and VAALCO does not anticipate asking Stifel to update its opinion. In rendering its opinion, Stifel made judgments and, with the consent of VAALCO, assumptions with regard to industry performance, general business, market and financial conditions and other matters that are beyond the control of VAALCO and TransGlobe. These include, among other things, the accuracy and completeness of the projections and other information provided to Stifel by or on behalf of VAALCO or TransGlobe, the consummation of the arrangement substantially on the terms and conditions described in the arrangement agreement, the absence of any material adverse change in the financial condition and prospects of VAALCO and TransGlobe, and the industry and financial markets in general, any of which could affect the public trading value of VAALCO common stock by the time the arrangement is completed.

Because the opinion was issued in connection with the signing of the arrangement agreement and is not expected to be updated, the opinion will not address the fairness to VAALCO, from a financial point of view, of the consideration to be paid by VAALCO to the TransGlobe shareholders pursuant to the arrangement at the time the arrangement is completed or as of any date other than the date of the opinion. The opinion also does not address the prices at which VAALCO common stock will trade at any time. The opinion that VAALCO received from Stifel is attached as Annex D to this proxy statement. For a description of the opinion, see “The Arrangement—Opinion of Financial Advisor to VAALCO” section of this proxy statement.

Completion of the arrangement may trigger change in control or other provisions in certain agreements to which TransGlobe is a party.

The completion of the arrangement may trigger change in control or other provisions in certain agreements to which TransGlobe is a party. If TransGlobe is unable to negotiate waivers of those provisions, the counterparties may exercise their rights and remedies under such agreements, potentially terminating such agreements, or seeking monetary damages. Even if TransGlobe is able to negotiate waivers, the counterparties may require a fee for such waivers or seek to renegotiate such agreements on terms less favorable to TransGlobe.

The combined company will face political risks in new jurisdictions.

TransGlobe’s principal operations, development and exploration activities and significant investments are held in Canada and Egypt, some of which may be considered to have an increased degree of political and sovereign risk. Any material adverse changes in government policies or legislation of such countries or any other country that TransGlobe has economic interests in that affect oil and gas exploration activities may affect the viability and profitability of the combined company following the arrangement.

While the governments in Canada, Egypt and other countries in which TransGlobe has oil and gas operations or development or exploration projects have historically supported the development of natural resources by foreign

TABLE OF CONTENTS

companies, there is no assurance that such governments will not in the future adopt different regulations, policies or interpretations with respect to, but not limited to, foreign ownership of oil and gas resources, royalty rates, taxation, rates of exchange, environmental protection, labor relations, repatriation of income or return of capital, restrictions on production or processing, price controls, export controls, currency remittance, or the obligations of TransGlobe under its respective oil and gas laws, code or standards. The possibility that such governments may adopt substantially different policies or interpretations, which might extend to the expropriation of assets, may have a material adverse effect on the combined company following the arrangement. Political risk also includes the possibility of terrorism, civil or labor disturbances and political instability. No assurance can be given that applicable governments will not revoke or significantly alter the conditions of the applicable oil and gas authorizations nor can assurance be given that such oil and gas authorizations will not be challenged or impugned by third parties. The effect of any of these factors may have a material adverse effect on the combined company’s results of operations and financial condition.

Upon consummation of the arrangement, VAALCO will become a reporting issuer in Canada and will therefore be subject to certain Canadian disclosure requirements.

Upon consummation of the arrangement, VAALCO will become a reporting issuer in each of the provinces of Canada and will be subject to Canadian continuous disclosure and other reporting obligations under applicable Canadian securities laws. Most Canadian continuous disclosure requirements are codified in National Instrument 51-102 – Continuous Disclosure Obligations (“NI 51-102”) of the Canadian Securities Administrators. The application of these requirements to VAALCO is modified by various rules providing exemptions for non-Canadian issuers in certain circumstances, including National Instrument 71-101 – The Multijurisdictional Disclosure System (“NI 71-101”) and National Instrument 71-102 – Continuous Disclosure and Other Exemptions Relating to Foreign Issuers (“NI 71-102”). NI 51-102 generally requires that issuers file audited annual financial statements and unaudited interim financial statements meeting certain requirements, management’s discussion and analysis relating to its annual and interim financial statements, an annual information form, material change reports and other disclosure items at prescribed times and/or upon the occurrence of certain specified events. VAALCO will be able to satisfy most of its Canadian reporting obligations under Canadian securities laws by filing certain of its U.S. disclosure documents in accordance with the exemptions codified in NI 71-101 and NI 71-102 on the System for Electronic Document Analysis and Retrieval at www.sedar.com. Nonetheless, VAALCO will be required to prepare and disclose its reserves information in accordance with the COGE Handbook and NI 51-101, and such disclosure standards differ from the SEC’s applicable disclosure requirements. See “—TransGlobe’s public filings are subject to Canadian disclosure standards, which differ from SEC disclosure requirements.” These additional reporting obligations will cause VAALCO to incur increased compliance costs and place increased demands on VAALCO management, administrative, operational and accounting resources and on VAALCO’s audit committee. As a general matter, VAALCO will not be able to cease to be a Canadian reporting issuer unless and until residents of Canada do not: (i) directly or indirectly beneficially own more than 2% of each class or series of outstanding securities (including debt securities) of VAALCO worldwide; and (ii) directly or indirectly comprise more than 2% of the total number of securityholders of VAALCO worldwide.

Upon consummation of the arrangement, VAALCO will be subject to the Canadian take-over bid regime pursuant to applicable Canadian securities laws.

Upon consummation of the arrangement, VAALCO will be subject to the Canadian take-over bid regime pursuant to applicable Canadian securities laws. In general, a take-over bid is an offer to acquire voting or equity securities of a class made to persons in a Canadian jurisdiction where the securities subject to the bid, together with securities beneficially owned, or over which control or direction is exercised, by a bidder, its affiliates and joint actors, constitute 20% or more of the outstanding securities of that class of securities. Subject to the availability of an exemption, take-over bids in Canada are subject to prescribed rules that govern the conduct of a bid by requiring a bidder to comply with detailed disclosure obligations and procedural requirements. Among other things, a take-over bid must be made to all holders of the class of voting or equity securities being purchased; a bid is required to remain open for a minimum of 105 days subject to certain limited exceptions; a bid is subject to a mandatory, non-waivable minimum tender requirement of more than 50% of the outstanding securities of the class that are subject to the bid, excluding securities beneficially owned, or over which control or direction is exercised, by a bidder, its affiliates and joint actors; and following the satisfaction of the minimum tender requirement and the satisfaction or waiver of all other terms and conditions, a bid is required to be extended for at least an additional 10-day period. There are a limited number of exemptions from the formal take-over bid requirements. In general, certain of these exemptions

TABLE OF CONTENTS

include the following: (i) the normal course purchase exemption permits the holder of more than 20% of a class of equity or voting securities to purchase up to an additional 5% of the outstanding securities in a 12-month period (when aggregated with all other purchases in that period), provided there must be a published market and the purchaser must pay not more than the “market price” of the securities (as defined) plus reasonable brokerage fees or commissions actually paid; (ii) the private agreement exemption exempts private agreement purchases that result in the purchaser exceeding the 20% take-over bid threshold, provided the agreement must be made with not more than five sellers and the sellers may not receive more than 115% of the “market price” of the securities (as defined); and (iii) the foreign take-over bid exemption exempts a bid from the formal take-over bid requirements if, among other things, less than 10% of the outstanding securities of the class are held by Canadian residents and the published market on which the greatest volume of trading in securities of the class occurred in the 12 months prior to the bid was not in Canada.

Increased exposure to foreign exchange fluctuations and capital controls may adversely affect the combined company’s earnings and the value of some of the combined company’s assets.

Our reporting currency is the U.S. dollar and the majority of our earnings and cash flows are denominated in U.S. dollars. The operations of TransGlobe are also reported in U.S. dollars, but TransGlobe conducts some of its business in currencies other than the U.S. dollar and, as a result, following the arrangement, the combined company’s consolidated earnings and cash flows may be impacted by movements in the exchange rates to a greater extent than prior to the arrangement. In particular, any change in the value of the currencies of the Canadian Dollar or the Egyptian Pound versus the U.S. dollar following the arrangement could negatively impact the combined company’s earnings, and could negatively impact the combined company’s ability to realize all of the anticipated benefits of the arrangement.

In addition, from time to time, emerging market countries such as those in which the combined company will operate adopt measures to restrict the availability of the local currency or the repatriation of capital across borders. These measures are imposed by governments or central banks, in some cases during times of economic instability, to prevent the removal of capital or the sudden devaluation of local currencies or to maintain in-country foreign currency reserves. In addition, many emerging markets countries require consents or reporting processes before local currency earnings can be converted into U.S. dollars or other currencies and/or such earnings can be repatriated or otherwise transferred outside of the operating jurisdiction. These measures may have a number of negative effects on the combined company, reduction of the immediately available capital that the combined company could otherwise deploy for investment opportunities or the payment of expenses. In addition, measures that restrict the availability of the local currency or impose a requirement to operate in the local currency may create other practical difficulties for the combined company.

The combined company will face new legislation and tax risks in certain TransGlobe operating jurisdictions.

TransGlobe has operations and conducts business in multiple jurisdictions in which we do not currently operate or conduct business, which may increase our susceptibility to sudden tax changes. Taxation laws in these jurisdictions are complex, subject to varying interpretations and applications by the relevant tax authorities and subject to changes and revisions in the ordinary course, which could result in an increase in TransGlobe’s taxes, or other governmental charges, duties or impositions, or an unreasonable delay in the refund of certain taxes owing to TransGlobe. No assurance can be given that new tax laws, rules or regulations will not be enacted or that existing tax laws will not be changed, interpreted or applied in a manner that could result in the combined company’s profits being subject to additional taxation, result in the combined company not recovering certain taxes on a timely basis or at all, or that could otherwise have a material adverse effect on the combined company.

Failure by VAALCO and/or TransGlobe to comply with applicable laws prior to the arrangement could subject the combined company to penalties and other adverse consequences following the arrangement.

We are subject to the provisions of the U.S. Foreign Corrupt Practices Act and the U.K. Bribery Act. TransGlobe is subject to the U.S. Foreign Corrupt Practices Act, the Corruption of Foreign Public Officials Act (Canada) and the U.K. Bribery Act. The foregoing laws prohibit companies and their intermediaries from making improper payments to officials for the purpose of obtaining or retaining business. In addition, such laws require the maintenance of records relating to transactions and an adequate system of internal controls over accounting. There can be no assurance that either party’s internal control policies and procedures, compliance mechanisms or monitoring programs will protect it from recklessness, fraudulent behavior, dishonesty or other inappropriate acts or adequately prevent or detect possible violations under applicable anti-bribery and anti-corruption legislation. Following the

TABLE OF CONTENTS

arrangement, the combined company may be responsible for any liability in respect of any of the foregoing attributable to VAALCO and/or TransGlobe prior to the arrangement. A failure by VAALCO or TransGlobe to comply with anti-bribery and anti-corruption legislation could result in severe criminal or civil sanctions, and may subject the combined company to other liabilities, including fines, prosecution, potential debarment from public procurement and reputational damage, all of which could have a material adverse effect on the business, consolidated results of operations and consolidated financial condition of the combined company following the arrangement. Investigations by governmental authorities could have a material adverse effect on the business, consolidated results of operations and consolidated financial condition of the combined company following the arrangement.

VAALCO and TransGlobe are also subject to a wide variety of laws relating to the environment, health and safety, taxes, employment, labor standards, money laundering, terrorist financing and other matters in the jurisdictions in which they operate. A failure by VAALCO and/or TransGlobe to comply with any such legislation prior to the arrangement could result in severe criminal or civil sanctions, and may subject the combined company to other liabilities, including fines, prosecution and reputational damage, all of which could have a material adverse effect on the business, consolidated results of operations and consolidated financial condition of the combined company following the arrangement. The compliance mechanisms and monitoring programs adopted and implemented by VAALCO and TransGlobe prior to the arrangement may not adequately prevent or detect possible violations of such applicable laws. Investigations by governmental authorities could also have a material adverse effect on the business, consolidated results of operations and consolidated financial condition of the combined company following the arrangement.

THE SPECIAL MEETING

Date, Time and Place

The special meeting will be held entirely online at the following website: https://www.virtualshareholdermeeting.com/EGY2022SM at 11:00 AM, Eastern Time, on September 29, 2022, or such other date, time and place to which the special meeting may be adjourned or postponed, for the purpose of considering and voting upon the amendment proposal and the share issuance proposal described in this proxy statement.

VAALCO stockholders may vote their shares electronically at the special meeting by following the instructions at https://www.virtualshareholdermeeting.com/EGY2022SM. VAALCO stockholders are also urged to vote their proxies by completing, signing, dating and returning the enclosed proxy card in the accompanying pre-addressed postage paid envelope, or to direct their brokers or other agents on how to vote the shares in their accounts, as applicable.

Purpose of the Special Meeting

At the special meeting, VAALCO is asking holders of shares of VAALCO common stock to vote on the following proposals:

(a)	Proposal No. 1 – The Amendment Proposal – to approve an amendment to the VAALCO Certificate of Incorporation to increase the authorized shares of VAALCO common stock from 100,000,000 shares to 160,000,000 shares; and

(b)	Proposal No. 2 – The Share Issuance Proposal – to approve the issuance of shares of VAALCO common stock to TransGlobe shareholders in connection with the arrangement agreement.

Board Recommendation

After determining that it is advisable and in the best interests of VAALCO and VAALCO stockholders to consummate the arrangement as contemplated by the arrangement agreement, the VAALCO board of directors unanimously authorized, approved, and declared advisable the issuance of shares of VAALCO common stock. Accordingly, the VAALCO board of directors unanimously recommends that VAALCO stockholders vote “FOR” each of the amendment proposal and the share issuance proposal.

VAALCO stockholders can cast separate votes on each proposal.

There are certain risks associated with the arrangement. See the “Risk Factors” section of this proxy statement for more information regarding such risks. VAALCO stockholders should carefully read this proxy statement in its entirety for more detailed information concerning the arrangement. In particular, VAALCO stockholders are directed to the arrangement agreement, which is attached as Annex A to this proxy statement.

Record Date; Outstanding Shares; Shares Entitled to Vote

The VAALCO board of directors has fixed the close of business on August 24, 2022 as the record date for determination of VAALCO stockholders entitled to notice of, and to vote at, the special meeting. Only VAALCO stockholders of record holding shares of VAALCO common stock as of the record date will receive notice of, and be entitled to vote at, the special meeting and any adjournments, postponements or continuations of the special meeting.

As of the record date for the special meeting, there were 59,826,544 shares of VAALCO common stock outstanding and held by approximately 82 VAALCO stockholders of record. Each VAALCO stockholder is entitled to one vote at the special meeting for each share of VAALCO common stock held by that stockholder at the record date. VAALCO common stock is the only security the holders of which are entitled to notice of, and to vote at, the special meeting.

If you own shares that are registered in the name of someone else, such as a broker, bank or other nominee, you need to direct that organization to vote those shares or vote the shares yourself at the special meeting.

Quorum

TABLE OF CONTENTS

Abstentions are counted for purposes of determining whether a quorum is present at the special meeting. Banks, brokers and other nominees that hold their customers’ shares in street name may not vote their customers’ shares on “non-routine” matters without instructions from their customers. As each of the amendment proposal and the share issuance proposal to be voted upon at the special meeting is considered “non-routine,” such organizations do not have discretion to vote on any proposal with a broker non-vote. As a result, since there are no matters in which a broker non-vote may be counted, if you fail to provide your broker, bank or other nominee with any instructions regarding how to vote your shares, your shares will not be considered present at the special meeting, will not be counted for purposes of determining the presence of a quorum and will not be voted on either of the amendment proposal or the share issuance proposal. If you provide instructions to your broker, bank or other nominee which indicate how to vote your shares with respect to one proposal but not with respect to the other proposal, your shares will be considered present at the special meeting and be counted for purposes of determining the presence of a quorum and voted, as instructed, with respect to the appropriate proposal, but will not be voted with respect to the other proposal.

VAALCO may adjourn the special meeting if a quorum is not present at the special meeting. Regardless of whether a quorum is present at the special meeting, VAALCO’s chair of the board or the person presiding as chairman of the special meeting may adjourn the special meeting to a later date, without notice other than announcement at the special meeting. If an adjournment is for more than 30 days, or if after the adjournment a new record date is fixed for the adjourned special meeting, VAALCO will provide notice of the adjourned special meeting to each VAALCO stockholder of record entitled to vote at that special meeting scheduled to a later date.

Beneficial Ownership of Securities

Unless otherwise noted, the following table reflects as of August 24, 2022 certain information known to VAALCO as to VAALCO common stock beneficially owned by (i) all those known to us to be holders of more than five percent of outstanding VAALCO common stock; (ii) each director and each of our named executive officers; and (iii) all current directors and executive officers as a group. As of August 24, 2022, there were 59,826,544 shares of VAALCO common stock outstanding. Unless otherwise noted, the mailing address of each person or entity named below is 9800 Richmond Avenue, Suite 700, Houston Texas 77042.

No director or executive officer (a) beneficially owned more than 1% of the outstanding shares of VAALCO common stock or (b) shares voting power in excess of 1% of the voting power of VAALCO’s outstanding capital stock. Each director and executive officer has sole voting power and dispositive power with respect to all shares beneficially owned by them, except as set forth below. It is expected that VAALCO’s directors and executive officers will vote “FOR” each of the amendment proposal and the share issuance proposal. Additionally, on July 13, 2022, in connection with the signing of the arrangement agreement, TransGlobe entered into support and voting agreements with VAALCO’s directors and certain members of VAALCO’s executive team, as described in “The Support and Voting Agreements” section of this proxy statement.

Required Vote

Assuming a quorum is present at the special meeting, approval of the adoption of the amendment proposal will require the affirmative vote of the holders of a majority of the outstanding shares of VAALCO common stock entitled to vote at the special meeting. An abstention from voting on the amendment proposal will have the same effect as voting against the amendment proposal. A broker non-vote will not be voted on the amendment proposal.

An abstention from voting on the share issuance proposal will have no effect on the outcome of the vote on the share issuance proposal. A broker non-vote will not be voted on the share issuance proposal.

Voting by Proxy

This proxy statement is being sent to you on behalf of the VAALCO board of directors for the purpose of requesting that you allow your shares of VAALCO common stock to be represented at the special meeting by the persons named in the enclosed proxy card. All shares of VAALCO common stock represented at the special meeting by properly executed proxy cards, voted over the telephone or voted over the internet will be voted in accordance with the instructions indicated on those proxies. If you sign and return a proxy card without giving voting instructions, your shares will be voted as follows:

•	“FOR” Proposal No. 1 – The Amendment Proposal – to approve an amendment to the VAALCO Certificate of Incorporation to increase the authorized shares of VAALCO common stock from 100,000,000 shares to 160,000,000 shares; and

•	“FOR” Proposal No. 2 – The Share Issuance Proposal – to approve the issuance of shares of VAALCO common stock to TransGlobe shareholders in connection with the arrangement agreement.

How to Vote

If you own shares of VAALCO common stock in your own name, you are an owner or holder of record. This means that you may use the enclosed proxy card or the internet or telephone voting options to tell the persons named as proxies how to vote your shares of VAALCO common stock. A 16-digit control number, located on your proxy card or voting instruction form, is designed to verify your identity and allow you to vote your shares of VAALCO common stock, and to confirm that your voting instructions have been properly recorded when voting over the internet or by telephone.

Whether or not you plan to attend the special meeting in person (online), you should submit your proxy as soon as possible. You have four voting options:

•	In Person. To vote in person, attend the special meeting in person (online) and you will be able to vote by ballot. To ensure that your shares are voted at the special meeting, the VAALCO board of directors recommends that you submit a proxy even if you plan to attend the special meeting.

TABLE OF CONTENTS

•	Mail. To vote using the enclosed proxy card, simply complete, sign and date the enclosed proxy card and return it promptly in the enclosed return envelope. If you return your signed proxy card to VAALCO before the special meeting, VAALCO will vote your shares as you direct.

•

Telephone. To vote by telephone, dial the toll-free telephone number located on the enclosed proxy card and follow the recorded instructions. You will be asked to provide the 16-digit control number from the enclosed proxy card. Your vote must be received by 11:59 PM, Eastern Time, on the day before the special meeting to be counted.

•

Internet. To vote over the internet, go to the web address located on the enclosed proxy card to complete an electronic proxy card. You will be asked to provide the 16-digit control number from the enclosed proxy card. Your vote must be received by 11:59 PM, Eastern Time, on the day before the special meeting to be counted.

If your shares of VAALCO common stock are held in “street name” by your broker, bank or other nominee, you should have received a voting instruction form with your 16-digit control number with these proxy materials from that organization rather than from Broadridge. Your broker, bank or other nominee will vote your shares only if you provide instructions to that organization on how to vote. You should provide your broker, bank or other nominee with instructions regarding how to vote your shares by following the enclosed procedures provided by that organization. Your shares will not be voted with respect to any proposal for which you fail to provide instructions, which will have (i) the same effect as a vote cast against the amendment proposal or (ii) no effect on the outcome of the vote on the share issuance proposal.

Revoking Your Proxy

Your grant of a proxy on the enclosed proxy card or through one of the alternative methods discussed above does not prevent you from voting in person (online) or otherwise revoking your proxy at any time before it is voted at the special meeting. If your shares of VAALCO common stock are registered in your own name, you may revoke your proxy in one of the following ways:

•	by submitting another proxy card bearing a later date and mailing it so that it is received before the special meeting;

•	by submitting another proxy using the internet or telephone voting procedures; or

•	by attending the special meeting and voting in person (online), although simply attending the special meeting will not revoke your proxy, as you must deliver a notice of revocation or vote at the special meeting in order to revoke a prior proxy.

Your last vote is the vote that will be counted.

If you have instructed a broker, bank or other nominee to vote your shares, you must follow the directions received from your broker, bank or other nominee if you wish to change your vote.

Voting in Person (Online) at the Special Meeting

All VAALCO stockholders may vote their shares in person (online) by attending the special meeting. If you are the beneficial owner of shares of VAALCO common stock, you are invited to attend the special meeting and should have received an instruction form bearing your 16-digit control number together with these proxy materials from your broker, bank or other nominee rather than from Broadridge. If you do not have your 16-digit control number, you may not be able to attend and vote your shares in person (online) at the special meeting, unless you call your broker, bank or other nominee to receive your 16-digit control number.

Adjournments and Postponements

Although it is not currently expected, the special meeting may be adjourned or postponed to a later date. Regardless of whether a quorum is present at the special meeting, VAALCO’s chair of the board or the person presiding as chairman of the special meeting may adjourn the special meeting to a later date, without notice other than announcement at the special meeting. If an adjournment is for more than 30 days, or if after the adjournment a new record date is fixed for the adjourned special meeting, VAALCO will provide notice of the adjourned special meeting to each VAALCO stockholder of record entitled to vote at that special meeting scheduled to a later date. Any

TABLE OF CONTENTS

adjournment of the special meeting for the purpose of soliciting additional proxies will allow VAALCO stockholders who have already sent in their proxies to revoke them at any time before voting occurs at the rescheduled special meeting.

Householding

Certain VAALCO stockholders who share an address are being delivered only one copy of this proxy statement unless VAALCO or one of its mailing agents has received contrary instructions. Upon the written or oral request of a stockholder at a shared address to which a single copy of this proxy statement was delivered, VAALCO will promptly deliver a separate copy of such document to the requesting stockholder.

In addition, VAALCO stockholders who wish to receive a separate copy of VAALCO’s proxy statements and annual reports, if any, in the future should notify VAALCO either in writing addressed to the foregoing address or by calling the foregoing telephone number. VAALCO stockholders sharing an address who are receiving multiple copies of VAALCO’s notice of internet availability of proxy materials and/or proxy statements and annual reports may request delivery of a single copy of such documents by writing to VAALCO at the address above or calling VAALCO at the telephone number above.

Inspector of Election; Tabulation of Votes

The VAALCO board of directors expects to appoint a representative of Broadridge Financial Solutions, Inc. to act as the inspector of election at the special meeting. The inspector of election will determine the number of shares outstanding, the shares represented at the special meeting, the existence of a quorum and the validity of proxies and ballots, and will count all votes and ballots.

Solicitation of Proxies

VAALCO is soliciting proxies for the special meeting from VAALCO stockholders. VAALCO will bear the entire cost of soliciting proxies from VAALCO stockholders, including the expenses incurred in connection with the preparation of the proxy statement and its filing with the SEC. In addition to this mailing, VAALCO’s directors, officers and employees, who will not receive any additional compensation for their services, may solicit proxies personally, electronically or by telephone. Arrangements also will be made with brokerage firms and other custodians, nominees and fiduciaries to forward proxy solicitation materials to the beneficial owners of VAALCO common stock held of record by those persons, and VAALCO will reimburse these brokerage firms, custodians, nominees and fiduciaries for related, reasonable out-of-pocket expenses they incur.

VAALCO has engaged D.F. King & Co., Inc. to assist in the solicitation of proxies for the special meeting and will pay D.F. King & Co., Inc. a fee of approximately $20,000, plus reimbursement of out-of-pocket expenses.

A list of stockholders entitled to vote at the special meeting will be open for examination by any VAALCO stockholder, for any purpose germane to the special meeting, during ordinary business hours for a period of ten days before the special meeting at VAALCO’s principal executive offices at 9800 Richmond Avenue, Suite 700, Houston, Texas 77042, and at the time and website of the special meeting during the entire time of the special meeting.

Other Business

VAALCO does not expect that any matter other than the amendment proposal and the share issuance proposal listed above will be brought before the special meeting. If, however, other matters are properly brought before the special meeting, or any adjournment or postponement of the special meeting, the persons named as proxies will vote in accordance with their judgment.

TABLE OF CONTENTS

THE ARRANGEMENT

This section of the proxy statement describes the material aspects of the proposed arrangement. This section may not contain all of the information that is important to you. You should carefully read this entire proxy statement and the documents incorporated by reference into this proxy statement, including the full text of the arrangement agreement, a copy of which is attached to this proxy statement as Annex A, for a more complete understanding of the proposed arrangement. In addition, important business and financial information about each of TransGlobe and VAALCO is included in, or incorporated by reference into, this proxy statement. See the “Where You Can Find More Information” section of this proxy statement.

Structure of the Arrangement

On July 13, 2022, VAALCO and AcquireCo entered into the arrangement agreement with TransGlobe, pursuant to which, among other things, AcquireCo will acquire all of the issued and outstanding TransGlobe common shares with TransGlobe becoming a direct wholly-owned subsidiary of AcquireCo and an indirect wholly-owned subsidiary of VAALCO. The arrangement will be implemented by way of a plan of arrangement in accordance with ABCA and is subject to approval by the Court, VAALCO stockholders and TransGlobe shareholders. The parties intend to rely upon the exemption from the registration requirements of the Securities Act pursuant to Section 3(a)(10) thereof with respect to the issuance of the VAALCO common stock under the arrangement. As TransGlobe is a corporation existing under the ABCA, the acquisition is being effected through an arrangement instead of a merger.

If the arrangement is completed, TransGlobe shareholders will receive the consideration shares consisting of 0.6727 of a share of VAALCO common stock for each TransGlobe common share, subject to adjustment (if any) pursuant to the arrangement agreement. No fractional shares of VAALCO common stock will be issued under the arrangement, and in lieu of any fractional shares of VAALCO common stock, each TransGlobe shareholder will be entitled to receive a cash payment equal to an amount representing such TransGlobe shareholder’s proportionate interest in the net proceeds from the sale by the depositary on behalf of all such TransGlobe shareholders of the excess of (i) the number of shares of VAALCO common stock issued and delivered to the depositary pursuant to the plan of arrangement, over (ii) the aggregate number of whole shares of VAALCO common stock to be issued to TransGlobe shareholders pursuant to the plan of arrangement. Any shares in respect of which dissent rights have been properly exercised and not withdrawn, pursuant to Section 191 of the ABCA, will be deemed to be transferred and assigned to VAALCO, but will not be entitled to receive consideration shares and will, instead, be subject to dissent rights under the ABCA, as modified by the plan of arrangement and the interim and final orders of the Court. VAALCO stockholders will continue to own their existing shares, and the VAALCO common stock will not be affected by the arrangement. Upon completion of the arrangement, it is expected that VAALCO stockholders will own approximately 54.5%, and TransGlobe shareholders will own approximately 45.5% of the combined company, calculated based on VAALCO’s vested and outstanding shares and TransGlobe’s outstanding shares, each as of the date of the arrangement agreement.

Background of the Arrangement

VAALCO’s senior management and board of directors (the “Board”) regularly explore, with the assistance of financial and legal advisors, potential strategic options available to VAALCO, with the goal of enhancing stockholder value. As part of this process, VAALCO regularly reviews a broad range of opportunities, including potential strategic acquisitions, joint ventures and business combinations with other oil and gas companies. The VAALCO Board and management have recognized that truly transformational opportunities are challenging and ongoing business development activities are required to identify and capitalize on opportunities.

Consequently, as part of VAALCO’s continuous assessment of its overall strategy, from time to time, VAALCO and its representatives engage in discussions with representatives of other companies concerning the possibility of such strategic transactions. In March 2019, VAALCO engaged an investment bank (the “prior financial advisor”) to assist VAALCO in identifying and evaluating attractive strategic transactions in line with VAALCO’s desired criteria. Later in March 2019, the prior financial advisor identified TransGlobe as a potential business combination target for VAALCO. VAALCO management recognized that an opportunity to combine with TransGlobe presented a unique transformational opportunity warranting further consideration. Accordingly, on March 25, 2019, VAALCO and TransGlobe executed a confidentiality agreement to enable the parties to share non-public information in connection with their mutual evaluation of a potential combination. While no actionable transaction ultimately resulted from such discussions (prior to the pending transaction), VAALCO’s senior management team kept the VAALCO Board apprised of the potential transactions being discussed with TransGlobe.

TABLE OF CONTENTS

Between March 2019 and December 2019, each party engaged in meetings and preliminary discussions regarding due diligence and analysis in connection with the evaluation of a potential transaction. An important part of the discussions concerned TransGlobe’s desire for the Merged Concession and the associated timeline. In December 2019, VAALCO decided to put its due diligence and other discussions with TransGlobe on hold because the Merged Concession had not yet received the needed approvals from the Egyptian government. However, VAALCO’s Board and senior management team continued to monitor TransGlobe’s progress on the Merged Concession, operations and performance.

In December 2020, TransGlobe announced that it reached an agreement with the Egyptian General Petroleum Corporation for its Merged Concession Agreement. The Merged Concession provided for a new 15-year development term, a 5-year extension option and amended fiscal terms. The effectiveness of the Merged Concession Agreement was subject to a customary Egyptian Parliamentary ratification and the satisfaction of other closing conditions. In December 2021, TransGlobe announced that the Merged Concession had been ratified by Egypt’s Parliament and signed into law by Egyptian President El-Sisi, and in January 2022, TransGlobe announced the execution of the Merged Concession Agreement.

On January 27, 2022, Mr. Robert Reynolds, Business Development Director of TransGlobe, contacted Mr. Thor Pruckl, executive vice president, international operations of VAALCO, via email enquiring whether VAALCO would be interested in resuming discussions regarding a potential transaction. Mr. Pruckl responded to Mr. Reynolds via email that he would follow up with Mr. George Maxwell, VAALCO’s chief executive officer and a director, regarding VAALCO’s interest in resuming such discussions.

In March 2022, as part of VAALCO’s regular reviews of a broad range of business combination opportunities, VAALCO’s management identified TransGlobe as a potential business combination opportunity that could potentially be effectuated with an all-stock transaction.

On March 22, 2022, at the request of Mr. Maxwell, Mr. David Cook, chairman of TransGlobe, met with Mr. Maxwell and Mr. Maxwell encouraged Mr. Cook to consider re-opening the discussions of a business combination between the two companies. Mr. Cook confirmed that a possible business combination warranted further discussions and diligence.

In March 2022, VAALCO asked its existing financial advisor, Stifel Nicolaus & Company, Incorporated (“Stifel”), to assist VAALCO with the evaluation of TransGlobe as a possible business combination target.

On March 25, 2022, the Strategic Committee of the VAALCO Board (the “Committee”), which included all members of VAALCO’s Board, namely: Mr. Andrew L. Fawthrop, VAALCO’s chairman, Mr. Fabrice Nze-Bekale, one of VAALCO’s directors, Ms. Catherine Stubbs, one of VAALCO’s directors, and Mr. Maxwell, met to discuss the possibility of re-engaging in discussions with TransGlobe. Also present at the meeting were Mr. Ron Bain, VAALCO’s chief financial officer, Mr. Michael Silver, VAALCO’s general counsel, and other VAALCO executives. A representative from Stifel also participated and presented to the Committee regarding TransGlobe. The Stifel representative noted that TransGlobe recently received approval of the Egyptian government for the Merged Concession resulting in TransGlobe benefiting from improved fiscal terms. The Stifel representative highlighted certain other strengths and potential weaknesses of TransGlobe, including a strong balance sheet with little long-term debt, payment obligations under the Merged Concession Agreement, a high sensitivity to oil prices, large commitments for cash payments and work programs, high general and administrative costs and other matters. The Stifel representative discussed the premium required in order to have an ownership split in the area of 50% VAALCO stockholders and 50% TransGlobe shareholders with the VAALCO directors constituting a majority of the combined company’s board. After further discussion, the Committee unanimously agreed that management should perform additional work to determine if a combination with TransGlobe made sense and could be beneficial for VAALCO’s stockholders.

Following the March 25, 2022 meeting, VAALCO engaged certain external consultants to conduct additional technical analysis and provide Stifel with a preliminary economic model.

On April 29, 2022, the Committee met to discuss updates regarding management’s evaluation of TransGlobe. Also present at the meeting were Mr. Bain, Mr. Silver and other VAALCO executives. A representative of Stifel was also present and provided an update on TransGlobe. Using publicly available information, the Stifel representative presented an updated preliminary analysis of TransGlobe and stated the business demonstrated potential for significant upside. The Stifel representative noted the attractive attributes of a business combination, including a

combined company with significant free cash flow, increased size, product diversity and increases to stockholder diversity and liquidity. The Stifel representative noted that access to non-public information concerning TransGlobe would be needed to take the analysis to the next stage. The Committee discussed the presentation and whether to provide an initial non-binding indication of interest to TransGlobe, noting that a combination with TransGlobe presented an excellent opportunity for transformational growth. After further discussion, the Committee unanimously agreed that the opportunity warranted further investigation and to providing an initial non-binding indication of interest to TransGlobe and approved sending a letter to TransGlobe’s chairman early in the following week.

On May 3, 2022, the Committee met to discuss updates regarding management’s evaluation of TransGlobe. Also present at the meeting were Mr. Bain, Mr. Silver and other VAALCO executives. Mr. Maxwell provided an update to the Committee on TransGlobe. A draft approach letter to TransGlobe had been prepared that proposed an all-share exchange based on an indicative value of C$6.88 per TransGlobe common share. This represented a premium of 25.5% to TransGlobe’s closing share price as of May 2, 2022 and a 29.1% premium to the 30-day volume weighted average price (“VWAP”). The approach letter also proposed a two-month exclusivity period. The Committee discussed the proposed valuation in the context of recent precedent transactions in the Middle East, North Africa, Canada and the U.K. After further discussion, the Committee unanimously approved sending the approach letter, but clarified that it had not come to a definitive view on valuation.

Later on May 3, 2022, Mr. Maxwell telephoned Mr. Cook to advise him that an approach letter would be forthcoming. Mr. Maxwell then delivered the approach letter, by email, to Mr. Cook later that day.

On May 4, 2022, Mr. Cook advised Mr. Maxwell that the TransGlobe board of directors had met to consider the approach letter and that TransGlobe was formulating its response.

On May 6, 2022, Mr. Cook telephoned Mr. Maxwell to request that Mr. Maxwell coordinate a call between representatives of Evercore Partners International LLP, TransGlobe’s financial advisor (“Evercore”), and Stifel in order to discuss some questions TransGlobe and Evercore had regarding the approach letter. Mr. Maxwell agreed to coordinate such a call.

On May 7, 2022, representatives of Stifel and Evercore, conducted a videoconference call during which representatives of Evercore asked clarification questions regarding VAALCO’s plans for the combined business, due diligence requirements and process and timeline to explore a potential transaction.

On May 11, 2022, VAALCO provided an initial due diligence request list, reflecting input from its advisors, to TransGlobe.

On May 12, 2022, Mr. Maxwell telephoned Mr. Cook to seek feedback regarding the approach letter. Mr. Cook indicated that TransGlobe would respond positively with a desire to continue discussions.

On May 12, 2022, Mr. Cook delivered TransGlobe’s written response to the approach letter. TransGlobe’s response noted that while the valuation proposed by the approach letter was in the range that warranted serious consideration by TransGlobe and its board, further work concerning VAALCO’s assets would be needed to validate the indicated premium. Additionally, TransGlobe’s response noted that further understanding of VAALCO’s views regarding board and management composition of the combined company was needed. The response letter declined VAALCO’s request for exclusivity. Finally, the response letter attached a form of confidentiality agreement to be signed between the parties to facilitate further discussions and due diligence.

On May 16, 2022, VAALCO and TransGlobe executed a confidentiality agreement that contained a mutual 18-month standstill provision. The standstill provision would terminate upon expiration of the 18-month period or if the parties entered into a definitive written agreement in connection with a transaction.

On May 19, 2022, Mr. Maxwell spoke with Mr. Cook on the telephone. Mr. Maxwell expressed his desire to have TransGlobe’s management team give a management presentation to VAALCO. Mr. Cook requested that Mr. Fawthrop call Mr. Cook to discuss the composition of the board and executive management team following completion of a transaction.

On May 20, 2022, the Committee met to discuss updates regarding management’s evaluation of TransGlobe. Also present at the meeting were Mr. Bain and Mr. Silver. Mr. Maxwell provided an update on TransGlobe and discussed a project plan prepared by Mayer Brown International LLP and Mayer Brown LLP, VAALCO’s U.K. and U.S. counsel, respectively (“Mayer Brown”), listing various workflows across the relevant jurisdictions. Mr. Maxwell also discussed seeking a fairness opinion from Stifel, which the VAALCO Board would likely request.

TABLE OF CONTENTS

Mr. Maxwell summarized his call with Mr. Cook the previous evening. Mr. Maxwell also noted that representatives from Stifel and Evercore participated in a call earlier that day and agreed to a TransGlobe management presentation to be held on May 23, 2022. The Committee requested a timeline showing the anticipated duration of due diligence, reaching a decision and holding a VAALCO Board meeting.

On May 21, 2022, Mr. Fawthrop and Mr. Cook discussed the strategic merits of combining the companies. The conversation addressed the strengths of the combined portfolio, similarities of operating styles, and the breadth of market listings between the companies. There was a discussion regarding the role and importance of executive continuity and transition in the case of a successful combination. There was also a ‘no names in seats’ discussion regarding combined company’s board composition during which the two chairs agreed a balanced representation would be best in the combined company’s board. Mr. Cook noted that TransGlobe had a strong suite of directors for the combined company and outlined the core competencies of the TransGlobe directors, with reference to TransGlobe’s Director Competency Matrix.

On May 23, 2022 members of TransGlobe’s management team gave a presentation to the VAALCO management team and technical consultants over a videoconference. Also present were representatives from Stifel and Evercore.

During the period of May 23, 2022 to June 14, 2022, TransGlobe and VAALCO in conjunction with their respective advisors, Evercore and Stifel, conducted detailed technical, financial and commercial evaluations for the purpose of determining appropriate ownership ratios within a combined entity.

On May 24, 2022, TransGlobe provided VAALCO and its advisors access to a virtual data room containing due diligence materials.

Also on May 24, 2022, members of VAALCO’s management team gave a presentation to the TransGlobe management team over a videoconference. Also present were representatives from Stifel and Evercore.

On May 26, 2022, VAALCO provided TransGlobe and its advisors access to a virtual data room containing due diligence materials.

On May 30, 2022, representatives from Stifel and Evercore conducted a videoconference call during which an initial outline of an execution plan for the proposed transaction was discussed.

On June 1, 2022, TransGlobe’s management gave a technical presentation to the VAALCO technical team in response to questions previously prepared by VAALCO and shared with TransGlobe.

On June 2, 2022, the VAALCO Board met for its regularly scheduled meeting. Also present at the meeting were Mr. Bain, Mr. Silver and other VAALCO executives. Members of VAALCO’s management provided an update on the technical diligence on TransGlobe. Mr. Maxwell stated that a review of TransGlobe’s Egyptian assets demonstrated the existence of adequate drilling targets to justify the capital commitments required under the Merged Concession. Management also reviewed TransGlobe’s capital expenditures, work scope, 2022 production forecast and year ended 2021 reserves estimates. A subsequent Board meeting was scheduled for June 10, 2022 for a more detailed review, to confirm valuation and to decide whether to deliver a revised approach letter.

On each of June 7 and June 8, 2022, TransGlobe’s management gave follow-up technical presentations to the VAALCO technical team in response to questions previously prepared by VAALCO and shared with TransGlobe.

On June 10, 2022, the VAALCO Board met to discuss TransGlobe. Also present at the meeting were Mr. Bain, Mr. Silver, other VAALCO executives and representatives of Stifel and Mayer Brown. Mr. Maxwell provided an update on TransGlobe stating that technical due diligence was progressing. Mr. Maxwell also noted that VAALCO’s due diligence work demonstrated a strong potential upside for TransGlobe’s Egyptian assets but additional technical work would need to be completed in order to realize it. Mr. Maxwell stated that the VAALCO management team was interested in the prospect of being in a position to complete such technical work. However, because of the additional technical work that would be required, for purposes of the valuation negotiations, limited value was being ascribed to TransGlobe’s contingent resource estimates. The Stifel representative summarized the terms of the previous approach letter that included a C$6.88 per TransGlobe common share valuation and provided an updated preliminary valuation analysis. After reviewing TransGlobe’s technical model, the Stifel representative stated that the model demonstrated a high degree of confidence in TransGlobe’s base case. The assets demonstrated the possibility of organic upside but more technical work would need to be completed to realize it. The Stifel representative also discussed potential exchange ratios with the VAALCO Board, noting that market valuations had moved in

TABLE OF CONTENTS

VAALCO’s favor since the previous approach letter. The Stifel representative reviewed proposed bid parameters providing for VAALCO stockholders owning between 55% and 52% of the combined company which implied an exchange ratio of between 0.61 and 0.69 of a share of VAALCO common stock for each TransGlobe common share and a premium of 1% to 15%. The VAALCO Board engaged in discussions regarding Stifel’s presentation, and then discussed whether to continue the current process. After further discussion, the VAALCO Board unanimously approved continuing with the process and authorizing Stifel to engage with Evercore on valuation consistent with the parameters presented.

On June 13, 2022, representatives from Stifel and Evercore conducted a videoconference call during which representatives from Stifel and Evercore discussed the forward plan for the proposed transaction including key work streams and indicative timetable.

On June 14, 2022, the VAALCO Board met to discuss TransGlobe. Also present at the meeting were Mr. Bain and Mr. Silver. Mr. Maxwell provided an overview of a revised approach letter which included a non-binding indicative valuation of C$493.7 million, an implied price per TransGlobe common share of C$6.53 and a premium of 13.6% to TransGlobe’s 30-day VWAP. An exchange ratio was also included but Mr. Maxwell noted that the exchange ratio would only become final once an arrangement agreement was finalized and signed. The terms of the revised approach letter implied the combined company being owned 54.1% by VAALCO stockholders and 45.9% by TransGlobe shareholders. The revised approach letter also recognized TransGlobe’s desire for representation on the board and executive team of the combined company and proposed (i) adding three members of the TransGlobe board to the board of the combined company with Mr. Fawthrop remaining as chairman; and (ii) that the executive team of the combined company would be led by the executive officers of VAALCO. Mr. Maxwell summarized a telephone call he had with Mr. Cook the previous weekend explaining that the revised valuation of TransGlobe was primarily due to updated information regarding the cost pool for TransGlobe’s Egyptian assets. The VAALCO Board discussed the importance of the need for exclusivity and Mr. Maxwell proposed that he provide TransGlobe with a proposed exclusivity agreement with the revised approach letter. After further discussion, the VAALCO Board unanimously approved sending the revised approach letter and proposed exclusivity agreement to TransGlobe.

Later on June 14, 2022, Mr. Maxwell delivered the revised approach letter and a proposed exclusivity agreement that would expire on July 8, 2022 to TransGlobe. Mr. Cook sent an email to Mr. Maxwell indicating that the revised approach letter had been sent to the full TransGlobe board and that TransGlobe would endeavor to discuss and respond promptly.

Also on June 14, 2022, representatives from Stifel and Evercore conducted a videoconference call during which key changes in the underlying valuation of TransGlobe were discussed.

On June 17, 2022, representatives from Stifel and Evercore conducted a videoconference call during which valuation approach and key inputs were discussed.

On June 21, 2022, the VAALCO Board met to discuss TransGlobe. Also present at the meeting were Mr. Bain and Mr. Silver. Mr. Maxwell advised the Board that Evercore had stated to Mr. Maxwell that there had been a number of newly identified factors that would reduce the valuation, including an underestimation of the assumed brought forward Egyptian cost pool available. Mr. Maxwell advised the VAALCO Board that Evercore had stated that TransGlobe would require cash settlement of TransGlobe options, DSUs, PSUs and RSUs held by its executives which would result in a payout at the closing of the transaction equal to the implied share price for each security (at the applicable vesting percentage in the case of PSUs). Finally, Mr. Maxwell advised that the TransGlobe board was meeting that day and that he would advise the VAALCO Board of any developments arising from that meeting.

On June 22, 2022, Mr. Maxwell spoke with Mr. Cook on the telephone. The two discussed various outstanding points relating to valuation of the two companies.

On June 23, 2022, Evercore sent Stifel comments to the exclusivity agreement. Included in the comments was a termination provision in the event TransGlobe’s directors received an unsolicited approach from a third party, which the TransGlobe directors, having been advised by external counsel, concluded they were obliged to consider in order to fulfill their fiduciary duties. This provision was ultimately not included in the executed agreement.

TABLE OF CONTENTS

On June 24, 2022, the VAALCO Board met to discuss TransGlobe. Also present at the meeting were Mr. Bain and Mr. Silver. Representatives of Stifel also participated. Mr. Maxwell advised the Board that since the last meeting there had been amendments to the economic model for TransGlobe as well as changes to the relative stock prices of VAALCO and TransGlobe. Representatives from Stifel provided an update on their discussions with Evercore and an update on Stifel’s preliminary analysis of TransGlobe’s valuation. The main drivers of a reduced valuation included: inflation, changes to net cash and working capital, and required management payouts. Despite the decrease in valuation, because of TransGlobe’s share price movements since June 14, 2022, a similar exchange ratio to the one contained in the June 14, 2022 revised approach letter still provided an attractive premium to TransGlobe shareholders. A Stifel representative then discussed Stifel’s updated preliminary valuation analysis, which implied an ownership split of between 54.5% and 56.5% to VAALCO stockholders, and between 45.5% and 43.5% to TransGlobe shareholders, and an approximate exchange ratio of between 0.67 and 0.62 of a share of VAALCO common stock for each TransGlobe common share. The VAALCO Board discussed Stifel’s presentation and unanimously approved Stifel engaging in discussions with Evercore within the above summarized valuation parameters.

Later on June 24, 2022, Mr. Maxwell delivered a further revised approach letter to Mr. Cook providing for an exchange ratio of 0.66 of a share of VAALCO common stock for each TransGlobe share, in line with the prior approach letter. Mr. Maxwell also delivered a revised draft of an exclusivity letter with a term expiring on July 8, 2022.

Also on June 24, 2022, Osler, Hoskin & Harcourt LLP, VAALCO’s Canadian counsel (“Osler”), sent a first draft of the arrangement agreement to Burnet, Duckworth & Palmer LLP, TransGlobe’s Canadian counsel (“BDP”), and Paul, Weiss, Rifkind, Wharton and Garrison LLP, TransGlobe’s U.S. counsel (“PW”). The arrangement agreement draft included (i) mutual covenants restricting VAALCO and TransGlobe from soliciting or negotiating acquisition offers from or with third parties, subject to specified exceptions; (ii) mutual covenants restricting each company’s board from changing its recommendation to vote for the transaction, subject to specified exceptions; (iii) conditions precedent to the consummation of the arrangement, including: (a) approval of each company’s equity holders pursuant to applicable law or rules of relevant securities exchange; (b) approval of the Court; (c) a material adverse effect not having occurred for either company at closing; and (d) to the extent required or necessary, the approval or consent or waiver to the arrangement from any government entity in Canada or Egypt having been obtained; (iv) mutual covenants to provide assistance preparing needed filings with the U.S. and Canadian securities regulators; (v) reciprocal termination fee provisions due under specified circumstances in the amount of $15 million; (vi) a proposal that upon consummation of the arrangement all outstanding TransGlobe options, DSUs, PSUs and RSUs would remain outstanding with the TransGlobe common shares underlying such instruments being substituted with shares of VAALCO common stock; and (vii) a provision providing for three to-be-named existing members of the TransGlobe board to join the VAALCO Board upon closing.

On June 27, 2022, representatives from Stifel and Evercore conducted a videoconference call during which representatives from Stifel and Evercore continued their discussions on valuation. Evercore proposed an ownership split of 46% TransGlobe shareholders and 54% VAALCO stockholders. After consultation with VAALCO, representatives from Stifel responded on a follow-up call that Evercore’s proposal was outside of the VAALCO Board approved range and counter-proposed an ownership split of 45.5% to TransGlobe shareholders and 54.5% to VAALCO stockholders, which was inside the pre-approved range.

On June 28, 2022, a representative of Evercore telephoned a representative of Stifel and stated that VAALCO’s proposal of an ownership split of 54.5% to VAALCO stockholders and 45.5% to TransGlobe shareholders, in each case calculated based on VAALCO’s vested and outstanding shares and TransGlobe’s outstanding shares, was acceptable to TransGlobe.

Also on June 28, 2022, VAALCO and TransGlobe executed an exclusivity letter with an exclusivity period expiring on July 8, 2022.

From June 28 to June 30, 2022, VAALCO’s technical consultants visited TransGlobe’s offices in Calgary. Also on June 28, the technical consultants did a site visit to TransGlobe’s production operations site in Alberta.

Beginning on June 29, 2022, legal and financial advisors for each of VAALCO and TransGlobe had a standing daily advisors’ call to discuss progress and negotiation of the legal documentation for the proposed transaction.

TABLE OF CONTENTS

On June 29, 2022, TransGlobe provided its initial responses to the legal due diligence request list previously sent by Mayer Brown.

On June 30, 2022, BDP sent comments to the arrangement agreement to Mayer Brown and Osler. BDP’s comments reflected open issues, including: (i) the treatment of TransGlobe’s outstanding options, DSUs, PSUs and RSUs, which remained an open point; and (ii) the amount of the termination fee.

Also on June 30, 2022, Osler sent an initial draft of the form of TransGlobe voting support agreement to BDP and PW.

On July 1, 2022, PW sent further comments to the arrangement agreement to Mayer Brown and Osler. PW’s comments concerned the tax treatment of the proposed transaction to existing TransGlobe shareholders. PW’s comments indicated that TransGlobe sought to have the proposed transaction be treated as a “plan of reorganization” within the meaning of U.S. Treasury regulations promulgated under Section 368(a) of the Code, which would generally be expected to result in U.S. holders of TransGlobe common shares not recognizing any gain or loss upon the receipt of consideration shares solely in exchange for TransGlobe common shares in the transaction.

On July 1, 2022, Osler sent an initial draft of the plan of arrangement to BDP and PW.

On July 3, 2022, Osler sent a revised draft of the arrangement agreement to BDP and PW.

Also on July 3, 2022, BDP provided comments to the form of TransGlobe voting support agreement to Mayer Brown and Osler.

Also on July 5, 2022, VAALCO, TransGlobe and each of their respective legal, accounting and financial advisors conducted a videoconference to discuss the tax treatment of the proposed transaction to existing TransGlobe shareholders. VAALCO expressed the desire to have the proposed transaction be structured as a taxable transaction with the goal of making a Section 338(g) election under the Code. VAALCO outlined the tax benefits to the combined company, especially in relation to post-closing corporate restructuring, were such an election to be made. Subsequent to this videoconference, no proposed comments were made to the arrangement agreement that were inconsistent with a Section 338(g) election being made by VAALCO.

On July 6, 2022, Mr. Maxwell, Mr. Randy Neely, TransGlobe’s chief executive officer, Mr. Geoff Probert, TransGlobe’s vice president and chief operating officer, and Mr. Craig Robertson, TransGlobe’s Egypt country manager, travelled to Cairo and met with the Egyptian First Undersecretary for Exploration and Agreements in the Ministry of Petroleum and Mineral Resources to discuss the possible combination of the companies.

On July 6, 2022, BDP provided comments to the TransGlobe voting support agreement to Mayer Brown and Osler.

Also on July 6, 2022, Mr. Fawthrop and Mr. Cook spoke on the telephone. Mr. Fawthrop asked for Mr. Cook’s recommendation on which TransGlobe board members would join the combined company’s board. Mr. Cook stated that all of TransGlobe’s non-executive directors had expressed interest in joining the combined company’s board. Mr. Cook advised that TransGlobe’s board was meeting the following day.

TABLE OF CONTENTS

On July 7, 2022, VAALCO and TransGlobe signed a new exclusivity agreement extending the expiry date of the exclusivity period to July 11, 2022. Osler also provided a revised draft of the arrangement agreement and an initial draft of the form of VAALCO voting support agreement, modeled on the form of TransGlobe voting support agreement, to BDP and PW.

On July 8, 2022, a representative from Stifel spoke with Mr. Eddie Ok, vice president, finance, chief financial officer and corporate secretary of TransGlobe on the telephone to enquire about the treatment of TransGlobe’s outstanding options, DSUs, PSUs and RSUs. Mr. Ok conveyed the determination of the TransGlobe board for treatment of TransGlobe’s outstanding options, DSUs, PSUs and RSUs. The TransGlobe board’s determination was that all outstanding options to acquire TransGlobe common shares granted under the TransGlobe stock option plan would be deemed vested and cancelled in exchange for a cash payment in accordance with TransGlobe’s stock option plan. In addition, each (i) DSU held by TransGlobe’s resigning directors; (ii) PSU held by TransGlobe’s departing employees; (iii) and RSU held by TransGlobe’s departing employees would be deemed to be fully and unconditionally vested (at the applicable vesting percentage, in the case of PSUs) and cancelled in exchange for a cash payment from TransGlobe. Further, all DSUs, PSUs and RSUs held by directors of TransGlobe who would join the VAALCO Board upon closing of the transaction, and held by employees who remained with the combined company upon closing of the transaction, would remain outstanding and continue to vest in accordance with their terms, provided that the applicable vesting percentage would be fixed at the effective time, and if an employee is terminated following the effective time, all of such employee’s unvested RSUs and PSUs, as applicable, would become fully vested and payable to the employee at the time of termination.

Also on July 8, 2022, VAALCO’s Board met to discuss TransGlobe. Also present at the meeting were Mr. Bain, Mr. Silver and other VAALCO executives and representatives of Stifel, Mayer Brown and Osler. At the meeting, Mr. Maxwell provided his views regarding the proposed transaction. Mr. Maxwell stated that the combination would create a company of greater size, significance and geographic diversity. Mr. Maxwell also noted that the proposed transaction would not require any financing or leveraging of the Company, and that a combined company would possess strong cash flows permitting stronger stockholder returns in the form of increased dividends and stock repurchases. Finally, Mr. Maxwell noted that a combined company’s larger scale would facilitate financing for future asset acquisitions. Representatives of Stifel presented their financial analysis and noted that the proposed transaction contemplated an ownership split of 54.5% owned by VAALCO stockholders and 45.5% owned by TransGlobe shareholders, which implied an exchange ratio of 0.6729 of a share of VAALCO common stock for each TransGlobe common share. Stifel then delivered its oral opinion, as of July 8, 2022, as to the fairness to VAALCO, from a financial point of view, of the consideration to be paid by VAALCO for the TransGlobe common shares pursuant to the arrangement agreement. No written opinion was delivered by Stifel in connection with the delivery of this oral opinion. During the meeting, the representatives of Mayer Brown and Osler discussed key legal considerations associated with the arrangement. A representative from Osler provided an overview of the key terms of the arrangement agreement and voting support agreements. A representative from Mayer Brown advised VAALCO’s Board of its fiduciary duties under Delaware law. Representatives from Mayer Brown also provided an update on the legal due diligence reports prepared by Mayer Brown, Osler, Al Kamel Law Firm, VAALCO’s Egyptian counsel, and Griffiths and Partners, VAALCO’s Turks & Caicos counsel. The Board discussed the proposed transaction and scheduled a subsequent Board meeting for July 10, 2022 to reach a final decision on the transaction following finalization of the relevant documents. The scheduled meeting was subsequently deferred until July 12, 2022 to allow for negotiation and completion of the necessary transaction documents.

On July 9, 2022, BDP provided comments to the arrangement agreement and plan of arrangement to Mayer Brown and PW.

Also on July 9, 2022, Mayer Brown informed BDP that TransGlobe’s treatment of the TransGlobe awards as outlined by Mr. Ok on July 8, 2022 was agreed.

On July 10, 2022, VAALCO executed an engagement letter with Stifel, formally hiring Stifel as exclusive financial advisor to VAALCO in connection with a potential transaction with TransGlobe.

On July 10, 2022, VAALCO’s Nominating and Corporate Governance Committee, which consisted of Mr. Nze-Bekale, Mr. Fawthrop and Ms. Stubbs, met to decide which of TransGlobe’s existing non-executive board members should join the combined company’s board after completion of the proposed transaction. Mr. Maxwell and Mr. Silver were also present. Background materials regarding existing TransGlobe directors had been provided in advance to the meeting. Desired qualifications for director candidates included experience in the oil and gas industry,

TABLE OF CONTENTS

other board experience and experience in Egypt and Canada. The Nominating and Corporate Governance Committee also discussed recommending a candidate with technical reserves expertise. After further discussion, the Nominating and Corporate Governance Committee unanimously adopted resolutions recommending to the board that three of TransGlobe’s directors, namely: Mr. Cook, Mr. Edward LaFehr and Mr. Timothy Marchant be appointed as directors upon completion of the arrangement to serve until VAALCO’s 2023 annual meeting of stockholders.

On July 10, 2022, Mr. Fawthrop telephoned Mr. Cook to communicate the recommendation adopted by VAALCO’s Nominating and Corporate Governance Committee earlier that day. Mr. Cook confirmed that the proposal to have Mr. Cook, Mr. LaFehr and Mr. Marchant join the combined company’s board was accepted.

Between July 10 and July 13, 2022, Osler, Mayer Brown, BDP and PW exchanged drafts of the arrangement agreement, plan of arrangement and voting support agreements.

On July 12, 2022, the VAALCO Board met to discuss TransGlobe. The meeting had been deferred for two days to allow for negotiation and completion of the necessary transaction documents. Also present at the meeting were Mr. Bain, Mr. Silver, other VAALCO executives and representatives of Stifel, Mayer Brown and Osler. Mr. Maxwell summarized developments since the prior Board meeting and the final items to be agreed in the arrangement agreement, the other transaction documents and announcement communications. A representative from Osler confirmed that the arrangement agreement, plan of arrangement and voting support agreements were complete and required only insertion of final transaction details. A representative from Stifel provided Stifel’s updated fairness analysis relating to a pro forma ownership split of 54.5% owned by VAALCO stockholders and 45.5% owned by TransGlobe shareholders, which implied an exchange ratio of 0.6739 of a share of VAALCO common stock for each TransGlobe common share. The Stifel representative also noted that based on the prior day’s closing share price for TransGlobe common shares, a termination fee of $9.8 million for each party was agreed. The Stifel representative concluded by delivering Stifel’s oral opinion as to the fairness to VAALCO, from a financial point of view, of the consideration to be paid by VAALCO for each of the TransGlobe common shares pursuant to the arrangement. No written opinion was delivered by Stifel in connection with the delivery of this oral opinion. The Board discussed the merits of the proposed transaction and unanimously approved the proposed transaction and execution of the transaction documentation.

Late in the evening on July 12, 2022, representatives from Stifel spoke on the telephone with representatives of Evercore. Stifel informed Evercore of a discrepancy that had been identified in VAALCO’s outstanding share count, and as a result, the exchange ratio would need to be modified in order to reflect the agreed upon pro forma ownership split of 54.5% owned by VAALCO stockholders and 45.5% owned by TransGlobe shareholders. Representatives of Stifel informed Evercore that additional time would be required to finalize the definitive agreements to reflect this development.

On July 13, 2022, the VAALCO Board met to discuss TransGlobe. Also present at the meeting were Mr. Bain, Mr. Silver, other VAALCO executives and representatives from Stifel, Mayer Brown and Osler. Mr. Maxwell summarized developments since the prior Board meeting on July 12, 2022. Mr. Maxwell stated that a discrepancy was identified in VAALCO’s outstanding share count and a 24-hour delay in approving and signing the arrangement agreement was required. Addressing the discrepancy resulted in a revision to the exchange ratio, as implied by the agreed ownership split of 54.5% owned by VAALCO stockholders and 45.5% owned by TransGlobe shareholders. The discrepancy also required Stifel to update its fairness analysis. A representative from Stifel provided Stifel’s updated fairness analysis noting a pro forma ownership split of 54.5% owned by VAALCO stockholders and 45.5% owned by TransGlobe shareholders implied an exchange ratio of 0.6727 of a share of VAALCO common stock for each TransGlobe common share. The Stifel representative also noted that based on the prior day’s closing share price for TransGlobe common shares, a revised termination fee of $9.15 million for each party had been agreed. The representative from Stifel concluded by delivering Stifel’s oral opinion (subsequently confirmed in writing) as to the fairness to VAALCO, from a financial point of view, of the consideration to be paid by VAALCO for each of the TransGlobe common shares pursuant to the arrangement. For a more detailed discussion of Stifel’s fairness analysis, see the section entitled “—Opinion of Financial Advisor to the VAALCO Board of Directors.” The Board discussed the merits of the proposed transaction and unanimously approved the proposed transaction and execution of the various deal documentation, as formalized in a unanimous written consent.

Later on July 13, 2022, VAALCO and TransGlobe agreed to the modified exchange ratio and termination fees and executed the arrangement agreement. VAALCO and TransGlobe also executed the voting support agreements with directors and officers of TransGlobe and VAALCO, respectively.

TABLE OF CONTENTS

VAALCO’s Reasons for the Arrangement

At its meeting on July 13, 2022, the VAALCO board of directors, among other things, unanimously (1) determined that the transactions contemplated by the arrangement agreement and the plan of arrangement are fair to VAALCO, and in the best interests of VAALCO and its stockholders and declared their advisability, (2) approved the arrangement agreement, the plan of arrangement and the VAALCO support and voting agreements and the transactions contemplated thereby, and (3) recommended to VAALCO stockholders that they approve the amendment proposal and the share issuance proposal. The VAALCO board of directors unanimously recommends that the VAALCO stockholders vote “FOR” each of the amendment proposal and the share issuance proposal.

In evaluating the arrangement, the VAALCO board of directors consulted with and received the advice of VAALCO management and legal and financial advisors. In reaching its decision, the VAALCO board of directors evaluated, among other things, the financial effects of the arrangement on VAALCO and its stockholders and the impact of the arrangement on VAALCO from a strategic and operational perspective. In doing so, the VAALCO board of directors considered a number of factors, including, but not limited to, the following factors, which the VAALCO board of directors viewed as supporting its decision to approve and enter into the arrangement agreement and recommend that the VAALCO stockholders vote “FOR” each of the amendment proposal and the share issuance proposal.

•

Complementary businesses creating a diversified, African-focused E&P. The arrangement will combine two crude oil and natural gas leaders to create a world-class, African-focused exploration and development company supporting a host of benefits to the combined company’s stockholders and other stakeholders; and creating a full-cycle portfolio of strong assets in Egypt, Gabon, Equatorial Guinea and Canada under a production and development-oriented business model.

•

Complementary Production and Reserves Bases. The combined company will have a larger more diversified reserves and production base, enhancing risk management, increasing portfolio optionality to high-grade and sequence investment projects towards the projects with attractive returns, as well as increasing access to a broader set of capital sources relative to each company on a standalone basis. The management of VAALCO estimates:

○

combined 2022 production guidance range of 17,700 to 19,000 barrels of oil equivalent per day, and combined 2023 preliminary outlook production range of 17,500 to 21,500 barrels of oil equivalent per day (96% oil & liquids) on a net revenue interest (“NRI”) basis across Egypt, Gabon and Canada, a 15% increase on a per share basis, calculated on the basis of VAALCO’s vested and outstanding shares and TransGlobe’s outstanding shares, each as of the date of the arrangement agreement; and

○	pro forma proved reserves of 32.4 million barrels of oil equivalent (83.2% oil), a 56.3% increase on a per share basis, calculated on the basis of VAALCO’s vested and outstanding shares and TransGlobe’s outstanding shares, each as of the date of the arrangement agreement.

•

Robust Balance Sheet. The combined company will be in a strong financial position, with US$97.9 million cash and cash equivalents as of June 30, 2022 (prior to receipt of $70.3 million in July and August 2022 from VAALCO’s May and June 2022 liftings) and $3.1 million in long-term debt, in each case on a pro forma combined basis, and the combined company will have access to additional liquidity under VAALCO’s existing facility agreement ($50.0 million undrawn as of June 30, 2022) and TransGlobe’s ATB Facility ($17.4 million (C$22.5 million) of which $3.1 million (C$4.0 million) was drawn as of June 30, 2022), which provides the combined company with the financial flexibility to invest in projects with attractive returns through continued disciplined capital allocation in the future.

•

Strong Financial Framework Supporting Enhanced Stockholder Returns. The arrangement will allow VAALCO stockholders to participate in the benefits of the combined company, including: (i) subject to board approval, a target annual dividend of US$28 million (approximately US$0.25 per share, calculated based on VAALCO’s vested and outstanding shares and TransGlobe’s outstanding shares, each as of the date of the arrangement agreement), subject to completion of the arrangement; and (ii) an up to US$30 million (approximately US$0.27 per share equivalent, calculated based on VAALCO’s vested and outstanding shares and TransGlobe’s outstanding shares, each as of the date of the arrangement agreement) share buyback program, subject to completion of the arrangement.

TABLE OF CONTENTS

•	Enhanced Cost Saving Prospects. The combined company will have the potential to realize significant operational synergies with US$30 million to US$50 million in anticipated cost savings through 2030 that would otherwise not be possible on a standalone basis.

•

Opportunity to participate in growth prospects of the combined company. The combined company will have an attractive inventory of organic growth projects across the portfolio in all regions, and will be more favorably positioned to self-fund, optimize and generate value from these projects on account of the combined company’s superior operational and technical capabilities and financial resources, relative to each of VAALCO and TransGlobe on an individual basis. By combining the portfolios, the combined company will have greater optionality to optimize capital allocation and ranking, allowing for the company to prioritize high-grade investment opportunities to optimize returns.

•

Proven Team with Established Track Record of Value Creation. The combined company will feature proven and experienced oil and gas business leaders, at both the board and executive management team levels, with a demonstrable track record of creating and delivering value to stockholders along with the combination of two highly capable subsurface, technical, operational and business development teams enabling the pooling of operational best practices, skills and technology across the combined portfolio.

•

Enhanced Proposition for Global Capital Markets. The combined company will benefit from greater scale, diversification and financial resilience that are expected to provide access to a broader range of capital sources. Stockholders in the combined company should benefit from a more liquid investment, with an increased number of shares traded on the NYSE and LSE, a more diversified combined stockholder profile and increased visibility in the public capital markets. Furthermore, comparable companies of greater scale have achieved higher valuation multiples in public markets and, if there is a higher trading multiple for the combined company’s stock, this could provide an incremental benefit to stockholders as a result of the arrangement.

•

Enhanced Ability to Execute on Inorganic Growth Opportunities. The combined company will be well positioned to benefit from additional targeted inorganic growth in Africa, with reference to strict strategic, financial and operational criteria, that would otherwise not have been available to VAALCO on a standalone basis.

•

Financial analysis and opinion. Stifel presented its financial analysis to the VAALCO board of directors and also delivered its oral opinion, which were subsequently confirmed in writing, that as of the date of, and subject to various assumptions made, procedures followed, matters considered and limitations and qualifications as described in such written opinion, the consideration to be paid by VAALCO to the TransGlobe shareholders pursuant to the arrangement was fair, from a financial point of view, to VAALCO. For a more detailed description of the opinion of VAALCO’s financial advisor, see “The Arrangement—Opinion of Financial Advisor to VAALCO” section of this proxy statement.

•

Support of boards and management teams. The boards of directors of VAALCO and TransGlobe have unanimously recommended support for the arrangement. Additionally, all of the directors and members of executive team of each of VAALCO and TransGlobe have entered into support and voting agreements pursuant to which they have agreed, among other things, to vote in favor of, in the case of VAALCO, the amendment proposal and the share issuance proposal, and in the case of TransGlobe, the TransGlobe resolution. In the case of VAALCO, these support and voting agreements relate to shares comprising approximately 1.6% of issued and outstanding shares of VAALCO common stock as of the record date of the special meeting; and in the case of TransGlobe, these support and voting agreements relate to shares comprising approximately 2.6% of issued and outstanding TransGlobe common shares as of the record date of TransGlobe’s shareholder meeting.

•	Arm’s length transaction. The arrangement agreement is the result of arm’s length negotiations and includes terms and conditions that are reasonable in the judgment of the VAALCO board of directors.

•	Likelihood of completion. The likelihood that the conditions to completion of the arrangement will be satisfied prior to the outside date.

•	Exchange ratio and consideration shares. The arrangement agreement provides for an exchange ratio, which will not be adjusted as a result of possible changes in the market prices of common stock of VAALCO or TransGlobe common shares following the announcement of the arrangement, providing

TABLE OF CONTENTS

reasonable certainty as to the respective pro forma percentage ownership of VAALCO by the current VAALCO stockholders and TransGlobe shareholders. In addition, the all-stock transaction preserves the combined company’s cash resources for operational and investment purposes.

•

Business climate and review of alternatives. After reviewing the current and prospective business climate in the oil and gas industry, including the potential for further consolidation or acquisitions, and the benefits and risks of other strategic opportunities reasonably available to VAALCO, the VAALCO board of directors believes that the arrangement represents VAALCO’s best prospect for increasing stockholder value in the medium to long term.

•	Conduct of VAALCO’s business. The VAALCO board of directors believes that the restrictions imposed on VAALCO’s business and operations during the pendency of the arrangement are reasonable and not unduly burdensome.

•	Certain terms of the arrangement agreement. The VAALCO board of directors considered certain terms of the arrangement agreement including:

(a)

that the arrangement agreement imposes restrictions on TransGlobe’s ability to solicit or engage in discussions or negotiations regarding certain alternative acquisition proposals for TransGlobe, which are described in the “The Arrangement Agreement and the Plan of Arrangement—Non-Solicitation of Alternative Transactions and Changes of Recommendation” section of this proxy statement;

(b)	that there are limited circumstances in which the TransGlobe board of directors may terminate the arrangement agreement or change its recommendation that TransGlobe shareholders approve the arrangement;

(c)

that notwithstanding the limitations contained in the arrangement agreement on VAALCO’s ability to solicit interest from third parties and terminate the arrangement agreement, the arrangement agreement allows VAALCO to engage in discussions or negotiations regarding any unsolicited competing proposal for VAALCO received prior to the special meeting that constitutes or would reasonably be expected to result in a VAALCO superior proposal;

(d)

that the arrangement agreement allows the VAALCO board of directors to change its recommendation supporting the arrangement at any time (prior to the time that VAALCO stockholder approval of the VAALCO resolutions is obtained) following the VAALCO board of director’s good faith determination, after consultation with its outside legal counsel and financial advisors, that an alternative acquisition proposal constitutes a superior proposal or in response to an intervening event following the VAALCO board of directors’ good faith determination, after consultation with its outside legal counsel, that a failure to effect a change in recommendation would be inconsistent with its fiduciary duties under applicable law (see “The Arrangement Agreement and the Plan of Arrangement—Non-Solicitation of Alternative Transactions and Changes in Recommendation” section of this proxy statement);

(e)	VAALCO’s right to receive a termination fee of $9.15 million or up to a $2.00 million expense reimbursement in the event that the arrangement agreement is terminated in certain circumstances; and

(f)

that the amendment proposal must be approved by the affirmative vote a majority of the outstanding shares of VAALCO common stock, and that the share issuance proposal must be approved by the affirmative vote of the holders of a majority of shares of VAALCO common stock who, being present in person (online) or voting by proxy and entitled to vote at the special meeting, cast votes affirmatively or negatively on the share issuance proposal.

•

Other factors. The VAALCO board of directors also carefully considered the arrangement with reference to current economics, industry and market trends affecting each of VAALCO and TransGlobe in the oil and gas market, information concerning oil and gas reserves and oil and gas resources, business, operations, properties, assets, financial condition, operating results and prospects of each of VAALCO and TransGlobe and the historical trading prices of the VAALCO common stock and the TransGlobe common shares, taking into account the results of VAALCO’s due diligence review of TransGlobe and its properties.

TABLE OF CONTENTS

The VAALCO board of directors also considered a variety of risks and other potentially negative factors relating to the arrangement including the following material factors:

•

the fact that the arrangement agreement provides for an exchange ratio and that no adjustment will be made in the consideration shares to be received by TransGlobe shareholders under the arrangement as a result of a possible increase in the trading price of VAALCO common stock following the announcement of the arrangement;

•	the potential impact on the market price of VAALCO common stock and dilution of the voting interests of VAALCO stockholders as a result of the issuance of the consideration shares to TransGlobe shareholders;

•

the risks relating to the announcement and pendency of the arrangement and risks and costs to VAALCO if the completion of the arrangement is not timely, or does not occur at all, which may be for reasons beyond the control of VAALCO and/or TransGlobe, including the potential impact on the relationships between VAALCO and its employees, service providers, suppliers and other third parties, as well as the potential impact on the trading prices of VAALCO common stock;

•

the provisions of the arrangement agreement that restrict VAALCO’s ability to solicit possibly superior transactions and the required payment by VAALCO of a $9.15 million termination fee or up to a $2.00 million expense reimbursement in the event of the termination of the arrangement agreement under specified circumstances described under “The Arrangement Agreement and the Plan of Arrangement—Termination of the Arrangement Agreement” section of this proxy statement;

•	the requirement that VAALCO provide TransGlobe with an opportunity to propose revisions to the arrangement agreement prior to the VAALCO board of directors being able to change its recommendation to vote in favor of the amendment proposal and the share issuance proposal;

•	the requirement that, even if the VAALCO board of directors has changed its recommendation with respect to the amendment proposal or the share issuance proposal, VAALCO must hold the special meeting and bring such proposals for a vote at the special meeting;

•	the provisions of the arrangement agreement impose certain restrictions on the operations of VAALCO until completion of the arrangement;

•	the fact that the arrangement agreement provides for the ability of the TransGlobe board of directors to, under certain circumstances, in a manner adverse to VAALCO, withhold, withdraw, amend, modify or qualify its recommendation that TransGlobe shareholders approve the arrangement agreement;

•	the fact that substantial costs will be incurred by both VAALCO and TransGlobe in connection with the arrangement, including financial advisory fees and legal and other advisor fees, as well as the costs of integrating the businesses of VAALCO and TransGlobe;

•	the risk that management focus, employee attention and resources for other strategic opportunities, as well as employee attention to operational matters, could be diverted for an extended period of time while the parties work to complete the arrangement and integration process;

•

the challenges inherent in the combination of two business enterprises of this size and complexity, including the attendant risks that the anticipated production and operational synergies and other benefits sought to be obtained from the arrangement might not be achieved in the time frame contemplated or at all;

•	the risks associated with the effects of general competitive, economic, political and market conditions and fluctuations on VAALCO, TransGlobe and/or the combined company;

•

the challenges and costs of combining regulatory and administrative operations of a U.S. company and a Canadian company with assets located in Canada and Egypt, which could adversely affect the combined company’s operating results and hinder the achievement of the anticipated benefits of the arrangement; and

•	various other risks associated with the combination of the businesses of VAALCO and TransGlobe, some of which are described under the “Risk Factors” section of this proxy statement.

The information and factors described above and considered by the VAALCO board of directors in reaching its determinations and recommendations are not intended to be exhaustive, but include material factors considered by the VAALCO board of directors. In view of the wide variety of factors considered in connection with the evaluation

TABLE OF CONTENTS

of the arrangement and the complexity of these matters, the VAALCO board of directors did not find it useful to, and did not attempt to, quantify, rank or otherwise assign relative weights to these factors. In addition, individual members of the VAALCO board of directors may have given different weight to different factors.

Recommendation of the VAALCO Board of Directors

•	“FOR” the amendment proposal; and

•	“FOR” the share issuance proposal.

Opinion of Financial Advisor to VAALCO

With Stifel’s consent, the full text of Stifel’s opinion, which describes the assumptions made, procedures followed, matters considered and limitations and qualifications on the review undertaken, is attached as Annex D to this proxy statement and is incorporated into this proxy statement by reference. The description of Stifel’s opinion set forth in this proxy statement is qualified in its entirety by reference to the full text of Stifel’s opinion. Stifel’s opinion was prepared at the request and for the benefit and use of the VAALCO board of directors (in its capacity as such) in connection with its evaluation of the consideration to be paid by VAALCO from a financial point of view and did not address any other terms, aspects or implications of the arrangement. Stifel expressed no opinion as to the relative merits of the arrangement or any other transactions or business strategies discussed by the VAALCO board of directors as alternatives to the arrangement or the decision of the VAALCO board of directors to proceed with the arrangement, nor did Stifel express any opinion on the structure, terms (other than the consideration to the extent specified in the Stifel Opinion) or effect of any other aspect of the arrangement, including, without limitation, any Pre-Acquisition Reorganization (as defined in the arrangement agreement), any terms, aspects or implications of any voting agreement or any other agreement, arrangement or understanding to be entered into in connection with or contemplated by the arrangement or the other transactions contemplated by the arrangement agreement. Stifel’s opinion does not constitute a recommendation as to any action the VAALCO board of directors should take in connection with the arrangement or the other transactions contemplated by the arrangement agreement or any aspect thereof and is not a recommendation to any director of VAALCO on how such person should vote or act with respect to the arrangement or related transactions and proposals. Stifel’s opinion also does not constitute a recommendation to any security holder as to how such holder should vote or act with respect to the arrangement or related transactions or proposals.

In connection with Stifel’s opinion, Stifel, among other things:

•	reviewed the financial terms contained in a draft copy of the arrangement agreement dated July 13, 2022 and a draft copy of the form of plan of arrangement dated July 13, 2022;

•

•

reviewed and analyzed certain internal financial analyses, financial projections, reports and other information concerning VAALCO and TransGlobe prepared by the management of VAALCO and TransGlobe, respectively, including, without limitation, the projections (see “The Arrangement—Summary of Certain VAALCO and TransGlobe Financial Projections” section of this proxy statement), and utilized per instruction of VAALCO;

TABLE OF CONTENTS

•	discussed with certain members of VAALCO management the historical and current business operations, financial condition and prospects of VAALCO and TransGlobe and such other matters as Stifel deemed relevant;

•	reviewed and analyzed such other information and such other factors, and conducted such other financial studies, analyses and investigations and considered such other information as was deemed necessary or appropriate for purposes of Stifel’s opinion; and

•	took into account Stifel’s assessment of general economic, market and financial conditions and its experience in other transactions, as well as its experience in securities valuations and its general knowledge of the industry in which VAALCO and TransGlobe operate.

In rendering its opinion, Stifel relied upon and assumed, without independent verification, the accuracy and completeness of all of the financial and other information that was provided to Stifel by or on behalf of VAALCO or TransGlobe, or that was otherwise reviewed by Stifel, and did not assume any responsibility for independently verifying any of such information. With respect to the financial forecasts supplied to Stifel by VAALCO and TransGlobe (including, without limitation, the projections), Stifel assumed, at the direction of VAALCO, that they were reasonably prepared on the basis reflecting the best currently available estimates and judgments of the management of VAALCO and TransGlobe, as applicable, as to the future operating and financial performance of VAALCO and TransGlobe, as applicable, and that they provided a reasonable basis upon which Stifel could form its opinion. Without limiting the foregoing, Stifel assumed, at the direction of VAALCO and without independent verification, that the projections with respect to management payouts upon a change of control, inflation, well abandonment expenditures, cost savings and payment obligations under the fiscal regime of each applicable jurisdiction included in the financial forecasts supplied to us by VAALCO and TransGlobe (including, without limitation, the projections) were reasonably prepared and are consistent with the laws of the applicable jurisdictions and the terms of any applicable contracts or other governing documents or agreements. Such forecasts and projections were not prepared with the expectation of public disclosure. All such forecasted or projected financial information was based on numerous variables and assumptions that are inherently uncertain, including, without limitation, factors related to general economic and competitive conditions. Accordingly, actual results could vary significantly from those set forth in such forecasted or projected financial information. Stifel relied on this projected information without independent verification or analyses and did not in any respect assume any responsibility for the accuracy or completeness thereof. Stifel expressed no opinion as to the projections or any other estimates, forecasts or projections or the assumptions on which they were made.

Stifel also assumed that there were no material changes in the assets, liabilities, financial condition, results of operations, business or prospects of either VAALCO or TransGlobe since the respective dates of the last financial statements of each company made available to Stifel. Stifel relied upon the assessments of the managements of VAALCO and TransGlobe, as the case may be, as to the oil, natural gas and/or natural gas liquids reserves, and acquisition, disposition, drilling, completion, production and development activities and exploration projects of VAALCO and TransGlobe, and related expenditures and capital funding requirements for VAALCO’s and TransGlobe’s operations. Stifel has not made or, except for certain reserve reports relating to VAALCO and

TABLE OF CONTENTS

TransGlobe ((i) in the case of VAALCO, (A) the report on VAALCO’s reserves data as at December 31, 2021 by Netherland, Sewell & Associates, Inc., dated February 4, 2022 and (B) the Competent Person’s Report on VAALCO’s reserves data as at December 31, 2021 by Netherland, Sewell & Associates, Inc., dated March 12, 2022, and (ii) in the case of TransGlobe, the report on TransGlobe’s reserves data as at December 31, 2021 by GLJ Ltd., dated February 22, 2022), been provided with any independent evaluation or appraisal of the assets or liabilities (contingent, accrued, derivative, off-balance sheet or otherwise) of VAALCO, TransGlobe or any other entity nor did Stifel make any physical inspection of the properties or assets of VAALCO, TransGlobe or any other entity. Stifel does not conduct or provide geological, environmental or other technical assessments and does not have expertise in the evaluation of oil, natural gas liquids or natural gas reserves or properties, and expressed no view or opinion as to reserve quantities, or the exploration, development or production (including, without limitation, as to the feasibility or timing thereof and associated expenditures), of any properties of VAALCO, TransGlobe or any other entity. Without limiting the foregoing, Stifel assumed, based on the information provided by the management of TransGlobe and without independent verification, that, as of the date of Stifel’s opinion, TransGlobe would receive full payment from Egyptian General Petroleum Corporation on all outstanding accounts receivable resulting from the merger of its three Eastern Desert production-sharing concessions in Egypt. Estimates of values of companies and assets do not purport to be appraisals or necessarily reflect the prices at which companies or assets may actually be sold. Because such estimates are inherently subject to uncertainty, Stifel assumed no responsibility for their accuracy.

Stifel assumed, with VAALCO’s consent, that there were no factors that would delay or subject to any adverse conditions any necessary regulatory or governmental approvals, consents, releases or waivers and that all conditions to the arrangement (including any required regulatory approvals) would be satisfied and not waived. In addition, Stifel assumed that the definitive arrangement agreement and the definitive plan of arrangement would not differ materially from the drafts it reviewed. Stifel also assumed that the arrangement would be consummated substantially on the terms and conditions described in the arrangement agreement and the plan of arrangement, without any waiver or modification of any material term or condition by VAALCO or any other party and without any anti-dilution or other adjustment to the consideration, and that obtaining any necessary regulatory or other approvals, consents, releases and waivers or satisfying any other conditions for consummation of the arrangement would not have an adverse effect on VAALCO, TransGlobe or the arrangement. Without limiting the foregoing, Stifel assumed, at the direction of VAALCO, that no payment (including any assignment, change-of-control, consent fee, bonus or other payment) would be required to be made by either VAALCO or TransGlobe or any of their affiliates in connection with the arrangement to any governmental body, agency, authority or entity or to any employee, officer or representative of, or any person otherwise acting in an official capacity for or on behalf of any governmental body, agency, authority or entity. Stifel assumed, in all respects material to Stifel’s opinion, that the representations and warranties of VAALCO and TransGlobe in the arrangement agreement were true and correct and that all such parties would comply with each of their covenants in the arrangement agreement and the plan of arrangement. Stifel assumed that the arrangement would be consummated in a manner that complies with the applicable provisions of the Securities Act, the Exchange Act, and all other applicable federal and state statutes, rules and regulations and all applicable statutes, rules and regulations of other jurisdictions (including, without limitation, the United Kingdom, Canada, Egypt, Gabon and Equatorial Guinea). Stifel further assumed that VAALCO had relied upon the advice of its counsel, independent accountants and other advisors (other than Stifel) as to all legal, financial reporting, tax, accounting and regulatory matters with respect to VAALCO, the arrangement and the arrangement agreement.

Stifel’s opinion was limited to whether the consideration to be paid by VAALCO to the TransGlobe shareholders is fair to VAALCO, from a financial point of view, and did not address any other terms, aspects or implications of the arrangement, including, without limitation, the form or structure of the arrangement or any other part of the arrangement, any individual transaction or group of transactions, or the terms, conditions or any other aspect of any individual transaction or group of transactions, that is or are part of the arrangement, any consequences of the arrangement on VAALCO, the VAALCO stockholders, creditors or otherwise, or any terms, aspects or implications of any voting, support, stockholder or other agreements, arrangements or understandings contemplated or entered into in connection with the arrangement or otherwise. Stifel’s opinion also did not consider, address or include: (i) any other strategic alternatives currently (or which have been or may be) contemplated by the VAALCO board of directors or VAALCO; (ii) the legal, financial reporting, tax, accounting or regulatory consequences of the arrangement on VAALCO or the VAALCO stockholders; (iii) the fairness (financial or otherwise) of the amount, nature or any other aspect of any compensation to any of the officers, directors or employees of any party to the arrangement or any related entities, or class of such persons, relative to the compensation to the holders of such entity’s securities or otherwise; or (iv) the effect of the arrangement on, or the fairness of the consideration to be

received by, holders of any class of VAALCO’s securities, or any class of securities of any other party to any transaction contemplated by the arrangement agreement or the plan of arrangement. Furthermore, Stifel did not express any opinion as to the prices, trading range or volume at which VAALCO’s or TransGlobe’s securities would trade following public announcement or consummation of the arrangement.

Stifel’s opinion was necessarily based on economic, market, financial and other conditions as they existed on, and on the information made available to Stifel by or on behalf of VAALCO or its advisors, or information otherwise reviewed by Stifel, as of the date of Stifel’s opinion. It is understood that subsequent developments may affect the conclusion reached in Stifel’s opinion and that Stifel does not have any obligation to update, revise or reaffirm Stifel’s opinion. Further, as the VAALCO board of directors was aware, the credit, financial, stock and commodity markets had been experiencing unusual volatility and Stifel expressed no opinion or view as to any potential effects of such volatility on VAALCO, TransGlobe or the arrangement. Stifel’s opinion was solely for the information of, and directed to, the VAALCO board of directors for its information and assistance in connection with its consideration of the financial terms of the arrangement and should not be relied upon by any other person. Stifel’s opinion did not constitute a recommendation to the VAALCO board of directors or any other person as to how the VAALCO board of directors or any other person should vote or otherwise act on the arrangement or any other matter or to any shareholder of VAALCO or TransGlobe as to how any such shareholder should vote or act with respect to the arrangement or any other matter, or whether or not any shareholder of VAALCO or TransGlobe should enter into a voting, shareholders’, or affiliates’ agreement with respect to the arrangement, or exercise any dissenters’ or appraisal rights that may be available to such shareholder. In addition, Stifel’s opinion did not compare the relative merits of the arrangement with any other alternative transactions or business strategies which might have been available to VAALCO and did not address the underlying business decision of the VAALCO board of directors or VAALCO to proceed with or effect the arrangement.

Stifel is not a legal, tax, regulatory or bankruptcy advisor. Stifel did not consider any potential legislative or regulatory changes currently being considered or recently enacted by the United States Congress, the various federal banking agencies, the SEC, or any other regulatory bodies of the United States or any other jurisdictions, or any changes in accounting methods or generally accepted accounting principles that may be adopted by the SEC or the Financial Accounting Standards Board, or any changes in regulatory accounting principles that may be adopted by any or all of the federal banking agencies or the banking agencies of any other jurisdictions. Stifel’s opinion was not a solvency opinion and did not in any way address the solvency or financial condition of VAALCO or TransGlobe.

The following is a brief summary of the material financial analyses performed by Stifel in arriving at Stifel’s opinion and presented by Stifel to the VAALCO board of directors. Stifel conducted an analysis of the ratios of the pre-transaction stand-alone equity value of TransGlobe relative to the pre-transaction stand-alone equity value of VAALCO, in each case as implied by valuation analyses conducted by Stifel and described below. In conducting its analyses, Stifel used three primary methodologies: discounted cash flow analysis, selected public companies analysis, and selected precedent transactions analysis. Other than the selected precedent transactions analysis, which was only applied to TransGlobe, each of these valuation analyses yielded a range of implied equity values for TransGlobe and VAALCO, respectively. On the basis of the discounted cash flow analysis and the selected public companies analysis, Stifel then calculated a range of implied exchange ratios of the TransGlobe implied equity value per share relative to the VAALCO implied equity value per share. In addition, Stifel also performed a relative contribution analysis to assess the relative net asset valuation contributions from TransGlobe and VAALCO to the combined company.

In accordance with customary investment banking practice, Stifel employed generally accepted valuation methods and financial analyses in reaching Stifel’s opinion. These summaries of financial analyses alone do not constitute a complete description of the financial analyses Stifel employed in reaching its conclusions. The financial analyses summarized below include information presented in tabular format. The per share equity values implied by Stifel’s analyses are rounded to the nearest dollar. In order to fully understand the financial analyses used by Stifel, the tables must be read together with the text of each summary. The tables alone do not constitute a complete description of the financial analyses. The summary text describing each financial analysis does not constitute a complete description of Stifel’s financial analyses, including the methodologies and assumptions underlying the analyses, and if viewed in isolation could create a misleading or incomplete view of the financial analyses performed by Stifel. The summary text set forth below does not represent and should not be viewed by anyone as constituting conclusions reached by Stifel with respect to any of the analyses performed by it in connection with Stifel’s opinion.

TABLE OF CONTENTS

Rather, Stifel made its determination as to the fairness, from a financial point of view, of the consideration to be paid by VAALCO to the TransGlobe shareholders pursuant to the arrangement agreement on the basis of its experience and professional judgment after considering the results of all of the analyses performed.

Except as otherwise noted, the information utilized by Stifel in its analyses, to the extent based on market data, was based on market data as it existed on or before July 13, 2022, and is not necessarily indicative of current market conditions. The analyses described below do not purport to be indicative of actual future results or to reflect the prices at which any securities may trade in the public markets, which may vary depending upon various factors, including changes in interest rates, dividend rates, market conditions, economic conditions and other factors that influence the price of securities.

Discounted Cash Flow Analysis

TransGlobe

Stifel conducted a discounted cash flow analysis for the purpose of determining an implied equity value per TransGlobe common share. Stifel calculated the future after-tax cash flows that TransGlobe could be expected to generate from its proved reserves (“Low Case”) and proved and probable reserves (“Base Case” and “High Case,” with the latter reflecting a risked upside to the proved and probable reserves) as such reserves were estimated as of December 31, 2021, using forecasts provided by VAALCO management and TransGlobe management (including the projections), and adjusted such values to take into account general and administrative expenses, tax, payments in respect of cash-settled securities, net cash, working capital and other assets and liabilities as provided by the VAALCO management and the TransGlobe management. The present values of the future after-tax cash flows were determined using discount rates ranging from 10.5% to 15%, which were chosen by Stifel based upon an analysis of TransGlobe’s weighted average cost of capital, and then were divided by the number of TransGlobe common shares outstanding (as provided by the TransGlobe management) to arrive at a range of implied equity values per TransGlobe common share for each of the Low Case, Base Case and High Case.

At the direction of the management of VAALCO, Stifel conducted a discounted cash flow analysis for TransGlobe based on two different commodity price assumptions: strip pricing and sensitized pricing. Strip price assumptions were based on the following at July 12, 2022: the New York Mercantile Exchange strip pricing for WTI, the ICE futures pricing for Brent, and the AECO-C pricing for natural gas (which we refer to collectively as “strip pricing”). Sensitized price assumptions were based on the NYMEX strip pricing for Brent, WTI and AECO-C at July 12, 2022 for the second half of 2022, after which prices were held at a reduced, flat level from 2023 onward (which we refer to as “sensitized pricing”). The commodity price assumptions were as follows:

	Strip Pricing			Sensitized Pricing
Year	Brent (US$/bbl)	WTI (US$/bbl)	AECO-C (C$/mcf)	Brent (US$/bbl)	WTI (US$/bbl)	AECO-C (C$/mcf)
H2 2022	98.8	95.4	3.6	98.8	95.4	3.6
2023	88.3	85.1	3.2	70.0	65.0	2.5
2024	83.1	78.3	3.1	70.0	65.0	2.5
2025	78.9	73.6	3.1	70.0	65.0	2.5
2026	76.1	70.0	3.2	70.0	65.0	2.5
2027	73.9	67.4	3.3	70.0	65.0	2.5
2028	72.6	65.9	3.4	70.0	65.0	2.5
2029	72.3	65.1	3.4	70.0	65.0	2.5
2030	72.3	65.0	3.5	70.0	65.0	2.5

Stifel calculated the net asset value of TransGlobe by adding (i) the present value of the net-entitlement cash flows (after accounting for the effect of asset specific fiscal regimes) generated by TransGlobe’s proved reserves or proved and probable reserves or a risked upside case of the proved and probable reserves, depending on which of the Low Case, Base Case or High Case applied, plus (ii) the amount of the back-dated entitlement payments receivable from Egyptian General Petroleum Corporation as a result of the merger of TransGlobe’s three Eastern Desert production-sharing concessions in Egypt, discounted to the present value, plus (iii) net cash, based on TransGlobe’s latest available unaudited consolidated balance sheet provided by the TransGlobe management, plus (iv) the net proceeds of the impending sale of TransGlobe’s Canadian Viking assets, as estimated by the TransGlobe

management, minus (v) working capital (excluding the back-dated Egyptian entitlement settlement described in (ii)), calculated based on TransGlobe’s latest available unaudited consolidated balance sheet provided by the TransGlobe management, minus (vi) the sum of the general and administrative expenses, corporate taxes, and liabilities in respect of cash settled securities, each as estimated by the management of VAALCO and discounted to their present values.

This analysis yielded a range of implied equity values for TransGlobe from which Stifel calculated a range of implied equity values per TransGlobe common share (calculated as implied equity values divided by the number of TransGlobe common shares outstanding), with the high values corresponding with the strip pricing and the low values corresponding with the sensitized pricing, as set forth in the table below:

	High*	Low*
Low Case	C$3.43	C$1.20
Base Case	C$4.89	C$2.92
High Case	C$6.12	C$4.12

*	Based on an exchange rate of 1.3013 Canadian Dollars per U.S. Dollar at July 12, 2022.

VAALCO

Stifel conducted a discounted cash flow analysis for the purpose of determining an implied equity value per share of VAALCO common stock. Stifel calculated the future after-tax cash flows that VAALCO could be expected to generate from its proved reserves (“Low Case”) and proved and probable reserves (“Base Case” and “High Case,” with the latter reflecting a risked upside to the proved and probable reserves) as such reserves were estimated as of December 31, 2021, using forecasts provided by VAALCO management, and adjusted such values to take into account general and administrative expenses, tax, net cash, working capital and other assets and liabilities as provided by the VAALCO management. The present values of the future after-tax cash flows were determined using a discount rate of 17.0%, which was chosen by Stifel based upon an analysis of VAALCO’s weighted average cost of capital, and then were divided by the number of shares of VAALCO common stock outstanding (as provided by the VAALCO management) to arrive at a range of implied equity values per share of VAALCO common stock for each of the Low Case, Base Case and High Case. At the direction of the management of VAALCO, Stifel conducted net asset valuation analyses for VAALCO based on the same strip pricing and sensitized pricing as used for TransGlobe.

Stifel calculated the net asset value of VAALCO by adding (i) the present value of the net-entitlement cash flows (after accounting for the effect of asset specific fiscal regimes) generated by VAALCO’s proved reserves or proved and probable reserves or a risked upside case of the proved and probable reserves, depending on which of the Low Case, Base Case or High Case applied, plus (ii) net cash, based on VAALCO’s latest available unaudited consolidated balance sheet, provided by the VAALCO management, minus (iii) working capital, calculated based on VAALCO’s latest available unaudited consolidated balance sheet provided by the VAALCO management, minus (iv) the sum of the general and administrative expenses as estimated by the management of VAALCO and discounted to its present value.

This analysis yielded a range of implied equity values for VAALCO from which Stifel calculated a range of implied equity values per share of VAALCO common stock (calculated as implied equity values divided by the number of fully diluted shares of VAALCO common stock outstanding), with the high values corresponding with the strip pricing and the low values corresponding with the sensitized pricing, as set forth in the table below:

	High	Low
Low Case	$3.26	$2.70
Base Case	$4.55	$3.83
High Case	$9.88	$8.35

Relative

Based on these analyses, Stifel compared, with respect to each of the Low Case, Base Case and High Case, the low value of the TransGlobe implied equity value per share range to the low value of the VAALCO implied equity value per share range, and the high value of the TransGlobe implied equity value per share range to the high value of the VAALCO implied equity value per share range. This analysis yielded a range of implied exchange ratios

between TransGlobe common shares and VAALCO common stock (representing the number of shares of VAALCO common stock for which each TransGlobe common share would be exchangeable for, based on their respective implied equity values per share), as set forth in the following table:

	High/High*	Low/Low*
Low Case	0.8085	0.3415
Base Case	0.8259	0.5859

Selected Public Companies Analysis

TransGlobe

Stifel reviewed certain publicly available financial data and stock market information for several selected public companies in the E&P sector. These consist of international E&P peer companies of a similar size to TransGlobe that have operations in either Africa or Canada. The selected public companies were:

•	Kosmos Energy Ltd.

•	Energean plc

•	Africa Oil Corp

•	Tullow Oil plc

•	Seplat Energy plc

•	BWE Energy Ltd.

•	i3 Energy plc

•	Panoro Energy ASA

•	Orca Energy Group

•	Pharos Energy plc

•	Perpetual Energy Inc.

•	Wentworth Resources plc

•	SDX Energy plc.

For each selected public company, Stifel calculated multiples of enterprise value (defined as equity value, based on closing stock prices on July 12, 2022, plus total debt less cash) compared to projected earnings before interest, taxes, depreciation, and amortization, commonly referred to as EBITDA, for calendar year 2022, the twelve months following May 31, 2022 (NTM), and calendar year 2023, as obtained from publicly available sources. The third quartile and first quartile multiples for the selected public companies implied by this analysis are set forth in the table below:

	2022E	NTM	2023E
3^rd Quartile	2.77x	2.60x	2.44x
1^st Quartile	1.88x	1.73x	1.39x

Based on the selected ranges of EV/EBITDA multiples, Stifel calculated an implied range of enterprise values of TransGlobe by multiplying the 3^rd quartile and 1^st quartile values of the 2022, NTM and 2023 EV/EBITDA multiples by TransGlobe’s projected EBITDA for 2022, the twelve months following May 31, 2022 (NTM) and 2023, based on the Base Case and the proved and probable reserves production profile provided by TransGlobe management and adjusted by VAALCO management. EBITDA was calculated on a consistent basis for both companies on a net revenue basis, after royalties and the deduction of government or national oil company entitlement barrels, but before any incremental corporation tax.

TABLE OF CONTENTS

Based on these implied enterprise value ranges, Stifel calculated ranges of implied equity values for TransGlobe (calculated as enterprise value minus total debt plus cash). The per share equity value ranges for TransGlobe implied by this analysis are set forth in the table below (with the high and low values corresponding with the 3^rd quartile and 1^st quartile values, respectively, under each analysis):

	Implied Equity Value Per Share*
	High	Low
TransGlobe EV/2022 EBITDA Analysis	C$8.09	C$5.75
TransGlobe EV/NTM EBITDA Analysis	C$6.36	C$4.50
TransGlobe EV/2023 EBITDA Analysis	C$5.28	C$3.36

*	Based on an exchange rate of 1.3013 Canadian Dollars per U.S. Dollar at July 12, 2022.

No company utilized in the selected public company analysis is identical to TransGlobe. Stifel chose the selected public companies on the basis of various factors, including the size of the companies and the similarity of the lines of business, although no company is identical to TransGlobe. Accordingly, these analyses are not purely mathematical, but also involve complex considerations and judgments concerning the differences in financial and operating characteristics of the selected companies and other factors.

VAALCO

Stifel reviewed certain publicly available financial data and stock market information for several selected public companies in the E&P sector. These consist of international E&P peer companies of a similar size to VAALCO that have operations in Africa. The selected public companies were:

•	Kosmos Energy Ltd.

•	Energean plc

•	Africa Oil Corp

•	Tullow Oil plc

•	Seplat Energy plc

•	BWE Energy Ltd.

•	Panoro Energy ASA

•	Orca Energy Group

•	Pharos Energy plc

•	Wentworth Resources plc

•	SDX Energy plc.

For each selected public company, Stifel calculated multiples of enterprise value (defined as equity value, based on closing stock prices on July 12, 2022, plus total debt less cash) compared to projected EBITDA for calendar year 2022, the twelve months following May 31, 2022 (NTM), and calendar year 2023, as obtained from publicly available sources. The third quartile and first quartile multiples for the selected public companies implied by this analysis are set forth in the table below:

	2022E	NTM	2023E
3^rd Quartile	2.87x	2.44x	2.35x
1^st Quartile	1.77x	1.67x	1.30x

Based on the selected ranges of EV/EBITDA multiples, Stifel calculated an implied range of enterprise values of VAALCO by multiplying the 3^rd quartile and 1^st quartile values of the 2022, NTM and 2023 EV/EBITDA multiples by VAALCO’s projected EBITDA for 2022, the twelve months following May 31, 2022 (NTM) and 2023, based on the Base Case and the proved and probable reserves production profile provided by VAALCO management. EBITDA was calculated on a consistent basis for both companies on a net revenue basis, after royalties and the deduction of government or national oil company entitlement barrels, but before any incremental corporation tax.

TABLE OF CONTENTS

Based on these implied enterprise value ranges, Stifel calculated ranges of implied equity values for VAALCO (calculated as enterprise value minus total debt plus cash). The per share equity value ranges for VAALCO implied by this analysis are set forth in the table below (with the high and low values corresponding with the 3^rd quartile and 1^st quartile values, respectively, under each analysis):

	Implied Equity Value Per Share
	3^rd Quartile	1^st Quartile
VAALCO EV/2022 EBITDA Analysis	$11.13	$7.23
VAALCO EV/NTM EBITDA Analysis	$7.36	$5.34
VAALCO EV/2023 EBITDA Analysis	$3.91	$2.59

No company utilized in the selected public company analysis is identical to VAALCO. Stifel chose the selected public companies on the basis of various factors, including the size of the companies and the similarity of the lines of business, although no company is identical to VAALCO. Accordingly, these analyses are not purely mathematical, but also involve complex considerations and judgments concerning the differences in financial and operating characteristics of the selected companies and other factors.

Relative

Based on these analyses, Stifel compared (i) the low value of the TransGlobe EV/2022 EBITDA analysis to the low value of the VAALCO EV/2022 EBITDA analysis and the high value of the TransGlobe EV/2022 EBITDA analysis to the high value of the VAALCO EV/2022 EBITDA analysis, (ii) the low value of the TransGlobe EV/NTM EBITDA analysis to the low value of the VAALCO EV/NTM EBITDA analysis and the high value of the TransGlobe EV/NTM EBITDA analysis to the high value of the VAALCO EV/NTM EBITDA analysis, and (iii) the low value of the TransGlobe EV/2023 EBITDA analysis to the low value of the VAALCO EV/NTM EBITDA analysis and the high value of the TransGlobe EV/2023 EBITDA analysis to the high value of the VAALCO EV/NTM EBITDA analysis. Each of these analyses yielded a range of implied exchange ratios between TransGlobe common shares and VAALCO common stock (representing the number of shares of VAALCO common stock for which each TransGlobe common share would be exchangeable for, based on their respective implied equity values per share), as set forth in the following table:

	High/High*	Low/Low*
Relative EV/2022 EBITDA Analysis	0.5586	0.6112
Relative EV/NTM EBITDA Analysis	0.6641	0.6476

TABLE OF CONTENTS

Selected Precedent Transactions Analysis

TransGlobe

Stifel reviewed certain publicly available information relating to seven selected business combination transactions involving target companies comparable to TransGlobe in size and jurisdictions. The selected precedent transactions consist of international E&P transactions that are of a comparable size and/or have emerging market asset exposure and transactions involving Canadian listed E&P companies of a comparable size, in each case within the last five years. The selected precedent transactions are set forth in the table below:

Date Announced	Target Name	Acquiror Name
U.K. Transactions
11/15/2019	Amerisur Resources Plc	Geopark Limited
10/15/2019	Eland Oil & Gas plc	Seplat Energy Plc
3/20/2019	Ophir Energy Plc	Medco Energi Internasional PT
11/26/2018	Faroe Petroleum Plc	DNO ASA
Canadian Transactions
12/9/2020	TORC Oil & Gas Ltd	Whitecap Resources Inc.
11/9/2021	Storm Resources Ltd	Canadian Natural Resources Ltd
8/10/2020	Painted Pony Energy Ltd	Canadian Natural Resources Ltd

For each selected precedent transaction, Stifel calculated, among other things, the following statistics:

•	the premium of the per share consideration to the last closing price of the target company’s common stock prior to deal announcement;

•	the ratio of the target company’s enterprise value to its proved and probable reserves (measured in barrels of oil equivalent);

•	the ratio of the target company’s enterprise value to its average daily production (measured in barrels of oil equivalent per day); and

•	the ratio of the target company’s enterprise value to its projected EBITDA for the next twelve months.

Actual and estimated financial data of the selected transactions were based on publicly available information. The third quartile and first quartile statistics for the selected precedent transactions implied by this analysis are set forth in the table below:

	Premium to Last Closing Price	Enterprise Value / Proved and Probable Reserves ($/boe)	Enterprise Value / Average Daily Production ($/boepd)	Enterprise Value / NTM EBITDA
3^rd Quartile	60%	12.18	52,433	5.83x
1^st Quartile	15%	6.47	30,850	2.59x

Stifel then applied these ranges of multiples to the relevant TransGlobe metrics, including its closing price on July 12, 2022, its estimated proved and probable reserves, its projected EBITDA for the twelve months following May 31, 2022, and its estimated average daily production for the calendar year 2022, each as publicly disclosed or as provided by TransGlobe management and adjusted by VAALCO management. Based on these implied premium and enterprise value ranges, Stifel calculated ranges of implied equity values for TransGlobe. The per share equity value ranges for TransGlobe implied by these analyses are set forth in the table below:

	Implied Equity Value Per Share*
	3^rd Quartile	1^st Quartile
Premium to Last Closing Price Analysis	C$6.48	C$4.66
Enterprise Value / Proved and Probable Reserves Analysis	C$8.23	C$4.75
Enterprise Value / Average Daily Production Analysis	C$13.26	C$6.34
Enterprise Value / NTM EBITDA Analysis	C$8.00	C$5.04

*	Based on an exchange rate of 1.3013 Canadian Dollars per U.S. Dollar at July 12, 2022.

TABLE OF CONTENTS

No transaction utilized in the selected precedent transaction analysis is identical to the arrangement. Stifel chose the selected precedent transactions on the basis of various factors and no company is identical to TransGlobe. Accordingly, these analyses are not purely mathematical, but also involve complex considerations and judgments concerning the differences in financial and operating characteristics of the companies involved in the selected precedent transactions and other factors.

Relative Contribution Analysis

Based on the discounted cash flow analysis described above, Stifel performed a pro forma analysis to assess the relative contribution to the combined company of VAALCO’s and TransGlobe’s estimated net asset valuations, with respect to each of the Low Case, Base Case and High Case and using the strip pricing. The relative contributions of VAALCO and TransGlobe implied by this analysis are set forth in the table below:

	VAALCO	TransGlobe
Low Case	49.9%	50.1%
Base Case	49.4%	50.6%
High Case	62.9%	37.1%

Other Information

Historical Trading Range

For reference only and not as a component of its fairness analysis, Stifel reviewed the historical trading prices of the TransGlobe common shares. The last closing price of the TransGlobe common shares before the announcement of the arrangement agreement was C$4.05 per share, compared with an intraday trading range of C$1.92 to C$6.89 for the 52 weeks prior to the announcement of the arrangement agreement.

Analyst Price Target

For reference only and not as a component of its fairness analysis, Stifel reviewed certain publicly available equity research analyst price targets for the TransGlobe common shares available as of July 13, 2022, and noted that the range of such price targets was C$6.30 per share to C$7.43 per share.

Miscellaneous

The preparation of a fairness opinion is a complex process and is not necessarily susceptible to a partial analysis or summary description. In arriving at its opinion, Stifel considered the results of all of its analyses as a whole and did not attribute any particular weight to any analysis or factor considered by it. Stifel believes that the summary provided and the analyses described above must be considered as a whole and that selecting portions of these analyses, without considering all of them, would create an incomplete view of the process underlying Stifel’s analyses and opinion; therefore, the ranges of valuations and relative valuations resulting from any particular analysis described above should not be taken to be Stifel’s view of the actual valuation of TransGlobe or VAALCO or their relative valuation.

Stifel is acting as financial advisor to VAALCO in connection with the arrangement. VAALCO has agreed to pay Stifel for its services in connection with the proposed arrangement an aggregate fee of approximately $4.88 million, of which $1.00 million was payable upon delivery of Stifel’s opinion and the remainder is payable contingent upon consummation of the arrangement. In addition, VAALCO has agreed to pay Stifel a monthly advisory fee of $50,000, which is not contingent upon consummation of the arrangement and will cease upon Stifel’s termination as financial advisor to VAALCO. VAALCO has also agreed to reimburse Stifel for its expenses incurred in connection with Stifel’s engagement and to indemnify Stifel and its affiliates and their respective officers, directors, employees and agents, and any persons controlling Stifel or any of its affiliates, against specified liabilities. Stifel served as financial advisor to VAALCO in connection with its potential acquisition of certain assets in West Africa and has been paid a total fee of $275,268.53 as of the date of this proxy statement, all of which will be credited against the $4.88 million advisory fee payable to Stifel by VAALCO in connection with the proposed arrangement. In the ordinary course of business, Stifel and its clients may transact in the equity securities of each of VAALCO or TransGlobe or their affiliates and may at any time hold a long or short position in such securities. Stifel may seek to provide investment banking or financial advisory services to VAALCO and its affiliates in the future, for which

TABLE OF CONTENTS

Stifel would seek customary compensation. In its opinion, Stifel also confirmed to the VAALCO board of directors that there were no material relationships, other than as described above, that existed during the two years prior to the date of Stifel’s opinion or that were mutually understood to be contemplated in which any compensation was received or was intended to be received as a result of the relationship between Stifel and any party to the arrangement.

Summary of Certain VAALCO and TransGlobe Financial Projections

In connection with VAALCO’s consideration and evaluation of the arrangement, VAALCO management prepared and provided to the VAALCO board of directors, prior to finalizing the arrangement agreement, certain financial and other projections with respect to each of VAALCO (the “VAALCO projections”), TransGlobe (based on TransGlobe’s forecast as adjusted by VAALCO management, the “adjusted TransGlobe projections” together with the VAALCO projections, the “projections”). The projections also were provided to Stifel, and Stifel was instructed by VAALCO for its use and reliance with VAALCO’s consent in connection with its financial analysis and opinions as described in “The Arrangement—Opinion of Financial Advisor to VAALCO” section of this proxy statement.

VAALCO did not prepare the projections with a view toward public disclosure or the guidelines established by the American Institute of Certified Public Accountants for preparation and presentation of prospective financial information. Neither VAALCO’s independent registered public accounting firm, nor any other independent accountants, have compiled, examined or performed any procedures with respect to the projections, nor has any of them expressed any opinion or any other form of assurance on the projections or the achievability of the results reflected in the projections, and none of them assumes any responsibility for, and each of them disclaims any association with, the projections. Consequently, the inclusion of the projections should not be regarded as an indication that the VAALCO board of directors, VAALCO management, VAALCO, VAALCO’s financial advisor or any recipient of this information considered, or now considers, it to be an assurance of the achievement of future results.

The projections were prepared based on certain financial and other information regarding VAALCO and TransGlobe available to VAALCO management prior to finalizing the arrangement agreement on July 13, 2022. In developing the projections, VAALCO management applied a number of hypothetical assumptions in respect of a number of future matters that impact the projections. The projections for the Low Case were calculated assuming VAALCO and TransGlobe would be able to generate cash flow from their respective proved reserves and the Base Case and High Case were calculated VAALCO and TransGlobe would be able to generate cash flow from their respective proved and probable reserves with the latter reflecting a risked upside to proved and probable reserves. The projections, and the assumptions, opinions and judgments applied in developing the projections, were based on VAALCO management’s then best estimates and were not the subject of independent verification. As such, there can be no assurance that such assumptions, speculation, opinions or judgments are correct, nor that the projections will be achieved. The projections do not reflect subsequent estimates, including estimates related to annual pre-tax synergies, supply chain efficiencies and full potential improvements, following entry into the arrangement agreement. Based on this, the projections may not be an accurate representation of equivalent measures as at the date of this proxy statement. VAALCO can give no assurance that, had the projections been prepared either as of the date of the arrangement agreement or as of the date of this proxy statement, similar assumptions, estimates, opinions and judgments would be used.

The projections should be read in conjunction with the considerations described below under “—Important Information About the Projections and the Illustrative Scenarios.”

Summary of Certain Illustrative Hypothetical Case Scenarios Based Upon Various Oil Prices

On August 3, 2022, VAALCO disclosed that its South Tchibala 1HB0ST well had performed below expectations and revised its production guidance for the full year 2022 from between 9,500 and 10,500 barrels of oil equivalent per day to between 9,000 and 9,500 barrels of oil equivalent per day. Following this disclosure, on August 8, 2022, VAALCO management prepared the Illustrative Scenarios pertaining to the years ended 2022 and 2023 based upon various oil prices and taking into account its new production guidance and $4 million in cost synergies. The Illustrative Scenarios that are presented in order to provide stockholders with an indication as to the effect oil price movements may have on the combined company.

The Illustrative Scenarios were not prepared under the guidelines established by the American Institute of Certified Public Accountants for preparation and presentation of prospective financial information. Neither VAALCO’s independent registered public accounting firm, nor any other independent accountants, have compiled, examined or performed any procedures with respect to the Illustrative Scenarios, nor has any of them expressed any opinion or any other form of assurance on the Illustrative Scenarios or the achievability of the results reflected in the Illustrative Scenarios, and none of them assumes any responsibility for, and each of them disclaims any association with, the Illustrative Scenarios. Consequently, the inclusion of the projections should not be regarded as an indication that the VAALCO board of directors, VAALCO management, VAALCO, VAALCO’s financial advisor or any recipient of this information considered, or now considers, it to be an assurance of the achievement of future results.

The Illustrative Scenarios were prepared based on certain financial and other information regarding VAALCO and TransGlobe available to VAALCO management after finalizing the arrangement agreement on July 13, 2022. In developing the Illustrative Scenarios, VAALCO management applied a number of hypothetical assumptions in respect of a number of future matters that impact the Illustrative Scenarios. The Illustrative Scenarios were calculated using a range of assumed prices per barrel of oil. These assumed prices ranged from (i) $90.0 to $120.0 per barrel, in the case of 2022; and (ii) $88.3 to $120.0 per barrel, in the case of 2023. The Illustrative Scenarios, and the assumptions, opinions and judgments applied in developing the Illustrative Scenarios, are based on VAALCO management’s best estimates as of August 8, 2022 and were not the subject of independent verification. As such, there can be no assurance that such assumptions, speculation, opinions or judgments are correct, nor that any of Illustrative Scenarios will be achieved. Based on the foregoing oil price and other assumptions the VAALCO’s stand-alone estimated Adjusted EBITDA for 2022 is within a range of $190 million to $230 million; and the combined company’s estimated Adjusted EBITDA for 2023 is within a range of $350 million to $505 million. Adjusted EBITDA is a non-GAAP financial measure and is defined as earnings before interest, taxes, depreciation and amortization, adjusted to reflect the impact of hedging but before non-cash or unusual items, such as depletion and non-cash income and expenses.

The Illustrative Scenarios should be read in conjunction with the considerations described below under “—Important Information About the Projections and the Illustrative Scenarios.”

TABLE OF CONTENTS

Important Information About the Projections and the Illustrative Scenarios

Certain of the projections and Illustrative Scenarios summarized above were not prepared in accordance with U.S. GAAP, including Capital Expenditures, Operating Expenditures and Adjusted EBITDA. Non-U.S. GAAP financial measures should not be considered in isolation from, or as a substitute for, financial information prepared in accordance with U.S. GAAP. VAALCO’s calculation of non-U.S. GAAP financial measures may differ from others in the industry and Capital Expenditures, Operating Expenditures and Adjusted EBITDA are not necessarily comparable with similar titles used by other companies. VAALCO’s projections differ from TransGlobe’s projections because VAALCO’s usage of gross ownership interest in its projections denotes less than 100% working interest, while TransGlobe’s usage thereof denotes a full 100% working interest. The non-U.S. GAAP financial measures included in the projections were relied upon by VAALCO’s financial advisor for purposes of their separate financial analyses and opinions and by the VAALCO board of directors in connection with its consideration of the arrangement. Financial measures provided to a financial advisor in connection with a business combination transaction are excluded from the definition of non-U.S. GAAP financial measures and therefore are not subject to SEC rules regarding disclosures of non-U.S. GAAP financial measures, which would otherwise require a reconciliation of a non-U.S. GAAP financial measure to a U.S. GAAP financial measure. Reconciliations of non-U.S. GAAP financial measures were not relied upon by VAALCO’s financial advisor for purposes of their separate financial analyses and opinions or by the VAALCO board of directors in connection with its consideration of the arrangement. In addition, the SEC’s rules do not require a reconciliation of a forward-looking non-U.S. GAAP financial measure to a U.S. GAAP financial measure to the extent it is not available without unreasonable efforts. Accordingly, we have not provided a reconciliation of the financial measures.

The summary of the projections is not being included in this proxy statement to influence a stockholder’s decision whether to approve the amendment proposal and the share issuance proposal, but is being included to provide VAALCO stockholders with the projections that were made available to the VAALCO board of directors and VAALCO’s financial advisor. The Illustrative Scenarios are being included in this proxy statement in order to provide stockholders with an indication as to the effect oil price movements may have on the combined company. The inclusion of the projections and the Illustrative Scenarios in this proxy statement should not be regarded as an indication that VAALCO, TransGlobe or any of their respective affiliates, officers, directors, advisors or other representatives or any other recipient of this information considered or now considers the projections or Illustrative Scenarios to be necessarily predictive of actual future events or events which have occurred since the date of the projections or the Illustrative Scenarios, and the projections or the Illustrative Scenarios should not be relied upon as such. None of VAALCO, TransGlobe or any of their respective affiliates, officers, directors, advisors or other representatives can give any assurance that actual results will not differ materially from the projections and the Illustrative Scenarios. None of VAALCO, TransGlobe or any of their respective affiliates, officers, directors, advisors or other representatives has made or makes any representation to any VAALCO stockholder regarding the ultimate performance of VAALCO, TransGlobe or the pro forma combined company compared to the information contained in the projections or the Illustrative Scenarios or that the projections or the Illustrative Scenarios will be achieved.

The projections and Illustrative Scenarios, while presented with numerical specificity, reflect numerous variables, estimates and assumptions as to future events made by VAALCO management that such management believed were reasonable at the respective times the projections and Illustrative Scenarios were prepared, taking into account the relevant information available to such management at the respective times of preparation. However, such variables, estimates and assumptions are inherently uncertain and beyond the control of VAALCO management, including, among other things, VAALCO’s, TransGlobe’s and the pro forma combined company’s future financial performance, industry performance and activity, general business, economic, regulatory, market and financial conditions and competition, as well as changes to the business, financial condition or results of operations of the company, including the factors described in the “Cautionary Statement Regarding Forward-Looking Statements,” and the risks and uncertainties described in the “Risk Factors,” sections of this proxy statement, any of which may cause the projections, the Illustrative Scenarios or their respective underlying assumptions to be inaccurate. Some or all of the assumptions which have been made regarding, among other things, the timing of certain occurrences or impacts, may change or may have changed since the respective dates when the projections and Illustrative Scenarios were prepared. The projections and Illustrative Scenarios also reflect assumptions as to certain business decisions that are subject to change and, in many respects, subjective judgment, and thus are susceptible to multiple interpretations and periodic revisions based on actual experience and further or future business developments. VAALCO has not updated and, except as may be required by applicable law, does not intend to update or otherwise revise the projections or Illustrative Scenarios to reflect circumstances existing after the respective date when made or to reflect

TABLE OF CONTENTS

the occurrence of future events, even in the event that any or all of the assumptions on which the projections or Illustrative Scenarios were based are shown to be in error. There can be no assurance that the results reflected in any of the projections or Illustrative Scenarios will be realized or that actual results will not materially vary from the projections Illustrative Scenarios. In addition, since the projections and Illustrative Scenarios cover multiple years, such information by its nature becomes less predictive with each successive year. No one has made or makes any representation to any stockholder or any other investor regarding the information included in the projections or the Illustrative Scenarios.

In light of the foregoing and the uncertainties inherent in the projections, and considering that the special meeting will be held long after the projections and Illustrative Scenarios were prepared, stockholders and other investors are cautioned not to place undue, if any, reliance on the projections or the Illustrative Scenarios. Since the respective dates the projections and Illustrative Scenarios were prepared, VAALCO and TransGlobe have each made publicly available its respective actual results of operations for the three months ended June 30, 2022. You should review VAALCO’s Quarterly Report on Form 10-Q filed on August 10, 2022 and TransGlobe’s Current Report on Form 6-K filed on August 10, 2022 to obtain this information. See the “Where You Can Find More Information” section of this proxy statement.

Board of Directors Following the Arrangement

VAALCO has agreed with TransGlobe that it will take all actions necessary to ensure that, as of the effective time, the board of directors of VAALCO will consist of: (i) the four existing members of the VAALCO’s board of directors: Andrew L. Fawthrop, George Maxwell, Cathy Stubbs and Fabrice Nze-Bekale; and (ii) three members of TransGlobe’s existing board of directors: David Cook, Edward LaFehr and Timothy Marchant. Andrew L. Fawthrop will continue as the chairman of the VAALCO board of directors.

Management Following the Arrangement

VAALCO anticipates that its Chief Executive Officer and Chief Financial Officer will remain with VAALCO following the consummation of the arrangement.

Interests of VAALCO Directors and Executive Officers in the Arrangement

No current VAALCO directors or executive officers having served at any time since the beginning of 2021 own TransGlobe common shares as of the date of this proxy statement. None of VAALCO’s directors or executive officers or their associates has any substantial financial interest, direct or indirect, under the arrangement or the issuance of VAALCO common stock to TransGlobe shareholders under the arrangement, other than being a director or executive officer of VAALCO and a stockholder of VAALCO.

Assumption of Outstanding Financial Obligations of TransGlobe

Upon closing of the arrangement, VAALCO intends to assume, C$4.0 million (approximately $3.1 million) in indebtedness drawn by TransGlobe, as of June 30, 2022, on TransGlobe’s C$22.5 million (approximately $17.4 million) revolving Canadian reserves-based lending facility pursuant to the commitment letter dated May 16, 2017 between TransGlobe and ATB Financial (formerly Alberta Treasury Branches) as lender (as amended by amending agreements dated May 11, 2018, July 11, 2019, June 30, 2020 and June 3, 2021, the “ATB Facility”). For additional information regarding TransGlobe’s long-term debt, see TransGlobe’s consolidated financial statements, the notes thereto and the section entitled “Management’s Discussion and Analysis” contained in TransGlobe’s Current Report on Form 6-K, filed with the SEC on August 10, 2022, which are incorporated by reference into this proxy statement.

Accounting Treatment

TABLE OF CONTENTS

assumed from TransGlobe at their respective preliminary estimated fair values at the date of completion of the arrangement. Any excess of the purchase price (as described under Note 3(a) under “Unaudited Pro Forma Combined Financial Information—Notes to Unaudited Pro Forma Combined Financial Statements” section of this proxy statement) over the net fair value of such assets and liabilities will be recorded as goodwill.

The financial condition and results of operations of VAALCO after completion of the arrangement will include the financial condition and results of operations of TransGlobe after completion of the arrangement, but will not be restated retroactively to reflect the historical financial condition or results of operations of TransGlobe. The earnings of VAALCO following completion of the arrangement will reflect acquisition accounting adjustments, including the effect of changes in the carrying value for assets and liabilities on depletion expense, depreciation expense, amortization expense and interest expense. Indefinite-lived intangible assets, including goodwill, will not be amortized but will be tested for impairment at least annually, and all tangible and intangible assets including goodwill will be tested for impairment when certain indicators are present. If, in the future, VAALCO determines that tangible or intangible assets (including goodwill) are impaired, VAALCO would record an impairment charge at that time.

Federal Securities Laws Consequences; Stock Transfer Restrictions

Exemption from the Registration Requirements of the Securities Act

The consideration shares, pursuant to the arrangement, will not be registered under the Securities Act or the U.S. securities laws of any state of the United States and will be issued and exchanged in reliance upon the exemption from the registration requirements of the Securities Act pursuant to Section 3(a)(10) thereof. Section 3(a)(10) of the Securities Act exempts from the registration requirements under the Securities Act the issuance of securities which have been approved, after a hearing upon the substantive and procedural fairness of the terms and conditions of the relevant transaction, at which all persons to whom it is proposed the securities will be issued shall have the right to appear, by any court expressly authorized by law to grant such approval. Under the arrangement agreement, TransGlobe submitted the plan of arrangement to the Court on August 29, 2022 for an interim order after informing the Court of the intention to rely upon the exemption from the registration requirements of the Securities Act pursuant to Section 3(a)(10) thereof, and permitting notice to all persons to which the consideration shares will be issuable. The interim order was obtained on August 29, 2022. Following TransGlobe’s receipt of the interim order, the TransGlobe shareholder approval of the arrangement and a hearing at which such persons will have the right to appear, TransGlobe will seek a final order from the Court as to the substantive and procedural fairness of the plan of arrangement. Such final order is a condition to the consummation of the plan of arrangement and the issuance of the consideration shares. VAALCO therefore anticipates that, if the plan of arrangement becomes effective under the terms and conditions described in the arrangement agreement (including the receipt of such final order from the Court), the issuance of the consideration shares to the TransGlobe shareholders will be exempt from the registration requirements under the Securities Act pursuant to Section 3(a)(10) thereof.

Resales of VAALCO Common Stock After the Effective Time

The consideration shares to be received by TransGlobe shareholders in exchange for their TransGlobe common shares pursuant to the arrangement will be freely transferable under U.S. securities laws, except by persons who are “affiliates” (as defined in Rule 144) of VAALCO after the effective time, or were “affiliates” of VAALCO within 90 days prior to the effective time. Persons who may be deemed to be “affiliates” of an issuer include individuals or entities that control, are controlled by, or are under common control with, the issuer, whether through the ownership of voting securities, by contract, or otherwise, and generally include executive officers and directors of the issuer as well as principal shareholders of the issuer.

Any resale of VAALCO common stock by such an “affiliate” or former “affiliate” may be subject to the registration requirements of the Securities Act, absent an exemption therefrom, such as the exemption contained in Rule 144.

Material United States Federal Income Tax Consequences of the Arrangement

There are no material U.S. federal income tax consequences to VAALCO’s existing stockholders that will result from the issuance of VAALCO common stock under the arrangement.

Court Approvals

shareholder meeting and submit the arrangement to the TransGlobe shareholders for approval. Under the arrangement agreement, TransGlobe is required to seek the final order as soon as reasonably practicable, but in any event not later than five business days following the approval of the TransGlobe resolution by TransGlobe shareholders at TransGlobe’s shareholder meeting and the approval of the amendment proposal and the share issuance proposal by VAALCO stockholders at the special meeting, unless the Court’s operations are restricted in response to any COVID-19 measures. The Court hearing in respect of the final order is expected to take place on or about September 29, 2022 at 2:00 PM (Calgary Time) in Alberta, Canada, or as soon thereafter as is reasonably practicable.

The plan of arrangement will be implemented pursuant to Section 193 of the ABCA, which provides that, where it is impractical to effect an arrangement under any other provision of the ABCA, a corporation may apply to the Court for an order approving the arrangement proposed by such corporation. Pursuant to this section of the ABCA, such an application will be made by TransGlobe for approval of the arrangement. The Court has broad discretion under the ABCA when making orders with respect to plans of arrangement and the Court will consider, among other things, the fairness and reasonableness of the arrangement, both from a substantive and a procedural point of view. The Court may approve the arrangement either as proposed or as amended in any manner the Court may direct, subject to compliance with such terms and conditions, if any, as the Court thinks fit. Depending upon the nature of any required amendments, TransGlobe and/or VAALCO, each acting reasonably, may determine not to proceed with the transactions contemplated in the arrangement agreement. Prior to the hearing on the final order, the Court will be informed that the parties intend to rely on the exemption from the registration requirements under the Securities Act for the issuance of consideration shares pursuant to the arrangement, provided by Section 3(a)(10) thereof on the basis of the final order. There can be no assurance that the Court will approve the arrangement.

Regulatory Approvals

The TransGlobe Egyptian Parties are parties to two Concession Agreements with the EGPC and the Egyptian Government that provide exclusive rights to explore for and develop oil and gas in the South Ghazalat Area Western Desert and the merged development areas of West Bakr, West Gharib and Northwest Gharib Onshore. The Concession Agreements contain the Assignment Provisions, which provide that the TransGlobe Egyptian Parties may not assign any of their rights, privileges, duties or obligations under the Concession Agreements, directly or indirectly, without the written consent of the Egyptian Government. In addition, if the Assignment Provisions are triggered, (i) the EGPC has the right to acquire interest intended to be assigned on the same conditions, if it elects to do so within 90 days of receiving the final conditions (including the value of each assignment); and (ii) the TransGlobe Egyptian Parties would be required to pay a non-recoverable assignment fee to the EGPC in an amount equal to 10% of the value of each assignment deal upon the Egyptian Government’s approval of any assignment.

If the arrangement did trigger the Assignment Provisions, (i) consummation of the arrangement would require the written approval of the Egyptian Government; and (ii) the TransGlobe Egyptian Parties would be required to pay a non-recoverable assignment fee to the EGPC in an amount equal to 10% of the value of each assignment deal upon the Egyptian Government’s approval of any assignment. See “Risk Factors–TransGlobe’s Concession Agreements in Egypt contain assignment provisions and, if such assignment provisions were triggered by the arrangement, it could adversely affect the ability to consummate the arrangement or the benefits anticipated to be realized from the arrangement in a material manner.”

Nasdaq, AIM and TSX Delistings

The TransGlobe common shares are listed and posted for trading on the TSX and AIM under the trading symbol “TGL” and are listed on Nasdaq under the trading symbol “TGA.” Following the completion of the arrangement, the TransGlobe common shares will be delisted from the TSX , AIM and Nasdaq as promptly as practicable.

VAALCO common stock is currently listed for trading on the NYSE and the LSE under the trading symbol “EGY.” It is a condition to the completion of the arrangement that the shares of VAALCO common stock to be issued to TransGlobe shareholders in exchange for their TransGlobe common shares pursuant to the arrangement be

approved for listing on the NYSE. Accordingly, VAALCO has agreed to use commercially reasonable efforts to obtain approval of the listing of the consideration shares for trading on the NYSE. It is also a condition to the arrangement that the FCA must have acknowledged that the application for admission to trading on the Main Market has been approved and such admission has become effective. Additionally, VAALCO has agreed to use its commercially reasonable efforts to obtain by the effective time (i) acknowledgment from the FCA that the application for admission to trading on the Main Market has been approved; and (ii) acknowledgment from the LSE that the conditions to the consideration shares being admitted to trading on the Standard List have been satisfied. VAALCO will provide the required notice to the NYSE of the listing of the shares of VAALCO common stock to be issued in connection with the arrangement prior to the closing of the arrangement.

Fees, Costs and Expenses

All fees, costs and expenses incurred in connection with the arrangement agreement and the plan of arrangement will be paid by the party incurring those fees, costs or expenses. Pursuant to the arrangement agreement, however, certain termination fees or expense reimbursements are payable by VAALCO or TransGlobe if the arrangement agreement is terminated under certain circumstances.

NO APPRAISAL RIGHTS

Under the DGCL, holders of shares of VAALCO common stock are not entitled to appraisal rights in connection with the arrangement or any of the matters to be acted on at the special meeting.

THE ARRANGEMENT AGREEMENT AND THE PLAN OF ARRANGEMENT

The summary of the material provisions of the arrangement agreement and the plan of arrangement below and elsewhere in this proxy statement is qualified in its entirety by reference to the arrangement agreement, a copy of which is attached to this proxy statement as Annex A, and the plan of arrangement which is attached as Schedule A to the arrangement agreement. This summary may not contain all of the information about the arrangement agreement and the plan of arrangement that is important to you. We urge you to carefully read the arrangement agreement in its entirety, including all of its schedules, as it is the legal document governing the arrangement. The arrangement agreement contains representations and warranties that the parties have made to each other as of specific dates. The assertions embodied in the representations and warranties in the arrangement agreement were made solely for purposes of the arrangement agreement and the transactions and agreements contemplated thereby among the parties thereto, and may be subject to important qualifications and limitations agreed to by the parties thereto in connection with negotiating the terms thereof. The representations and warranties may also be subject to a contractual standard of materiality different from those generally applicable to stockholders and reports and documents filed with the SEC, and the assertions embodied in the representations and warranties contained in the arrangement agreement (and summarized below) are qualified by information in disclosure letters provided by TransGlobe to VAALCO and by VAALCO to TransGlobe in connection with the signing of the arrangement agreement and by certain information contained in certain of VAALCO’s and TransGlobe’s filings with the SEC. These disclosure letters and SEC filings contain information that modifies, qualifies and creates exceptions to the representations and warranties set forth in the arrangement agreement. In addition, information concerning the subject matter of the representations and warranties may have changed or may change after July 13, 2022 and subsequent developments or new information qualifying a representation or warranty may have been included in this proxy statement. In addition, if specific material facts arise that contradict the representations and warranties in the arrangement agreement, VAALCO or TransGlobe, as applicable, will disclose those material facts in the public filings that it makes with the SEC in accordance with, and to the extent required by, applicable law. Accordingly, the representations and warranties in the arrangement agreement, the plan of arrangement and their descriptions in this proxy statement should not be read alone, but instead should be read in conjunction with the other information contained in the reports, statements and filings VAALCO and TransGlobe publicly file with the SEC. For more information, see the “Where You Can Find More Information” section of this proxy statement.

The Arrangement

The arrangement agreement provides that at the effective time, AcquireCo will acquire all of the issued and outstanding TransGlobe common shares with TransGlobe becoming a direct wholly-owned subsidiary of AcquireCo and an indirect wholly-owned subsidiary of VAALCO. The arrangement will be implemented by way of a plan of arrangement in accordance with the ABCA and requires approval of (a) at least two-thirds of the votes cast by TransGlobe shareholders who vote in person or by proxy at TransGlobe’s shareholder meeting voting together as a single class; and (b) the Court.

The arrangement will become effective at the effective time on the date shown in the certificate of arrangement. If the final order is granted, and all other conditions to completion of the arrangement as set out in the arrangement agreement are satisfied or waived (to the extent that such conditions are capable of being satisfied prior to the effective date and, if waived, are not prohibited from being waived), the parties shall send to the registrar, for filing, the articles of arrangement and such other documents as may be required pursuant to the ABCA to give effect to the arrangement, as soon as is reasonably practicable and in any event no later than three business days after such satisfaction or waiver occurs, unless another time or date is agreed to in writing by the parties.

Consideration Shares Received Pursuant to the Arrangement

At the effective time, each TransGlobe common share outstanding immediately prior to the effective time (excluding shares held by VAALCO, AcquireCo or any of their respective affiliates or by shareholders that validly exercise, and do not withdraw, their dissent rights) will be deemed to be transferred and assigned to AcquireCo in exchange for 0.6727 of a share of VAALCO common stock, subject to adjustment (if any) pursuant to the arrangement agreement.

The consideration shares to be paid for TransGlobe common shares will be adjusted to reflect the economic effect of changes in the number of outstanding shares of VAALCO common stock that are issued and outstanding after the date of the arrangement agreement and prior to the effective time by reason of any split or consolidation of

TABLE OF CONTENTS

the issued and outstanding shares of VAALCO common stock and where, on or after the date of the arrangement agreement, any dividend or other distribution is declared, set aside or paid to TransGlobe shareholders or VAALCO stockholders of record as of a time prior to the effective time (except for regular quarterly dividends to VAALCO stockholders made in accordance with the arrangement agreement).

No fractional shares of VAALCO common stock will be issued as part of the arrangement. Instead, where the aggregate number of shares of VAALCO common stock to be issued to a TransGlobe shareholder as consideration would result in a fraction of securities of VAALCO being issuable, the number of VAALCO common stock to be received by such TransGlobe shareholder will be rounded down to the nearest whole VAALCO common stock. In lieu of any such fractional VAALCO common stock, each TransGlobe shareholder otherwise entitled to a fractional interest in a share of VAALCO common stock will be entitled to receive a cash payment equal to an amount representing such TransGlobe shareholder’s proportionate interest in the net proceeds from the sale by the depositary on behalf of all such TransGlobe shareholders of the excess of (i) the number of shares of VAALCO common stock issued and delivered to the depositary pursuant to the plan of arrangement, over (ii) the aggregate number of whole shares of VAALCO common stock to be issued to TransGlobe shareholders pursuant to the plan of arrangement.

At the effective time, on the terms and subject to the conditions of the arrangement agreement and the plan of arrangement, each TransGlobe option that is outstanding immediately prior to the effective time will be deemed to be fully and unconditionally vested and exercisable and surrendered and transferred to TransGlobe for cancellation in exchange for a cash payment from TransGlobe equal to the amount (if any) by which (x) the product of the Closing VWAP multiplied by the exchange ratio exceeds (y) the exercise price thereof and for greater certainty, where such amount is zero or negative, none of TransGlobe, VAALCO or AcquireCo or the depositary will be obligated to pay to the holder of such TransGlobe option any amount in respect such TransGlobe option.

At the effective time, on the terms and subject to the conditions of the arrangement agreement and the plan of arrangement, each (i) DSU held by persons other than the three directors of TransGlobe who will be appointed to the VAALCO board of directors namely David Cook, Edward LaFehr and Timothy Marchant; (ii) PSU held by TransGlobe’s departing employees; and (iii) RSU held by TransGlobe’s departing employees will be deemed to be fully and unconditionally vested (at the applicable vesting percentage determined by the TransGlobe board of directors, in the case of PSUs, which percentage will not exceed 200%) and surrendered and transferred to TransGlobe for cancellation in exchange for a cash payment from TransGlobe equal to the product of the Closing VWAP multiplied by the exchange ratio. All DSUs, PSUs and RSUs not described in the preceding sentence that are outstanding immediately prior to the effective time will remain outstanding and the terms of such DSUs, RSUs and PSUs will continue to be governed by the applicable plan provided that each such applicable plan will be amended so as to substitute for TransGlobe common shares underlying such DSUs, RSUs and PSUs, a number of shares of VAALCO common stock (rounded down to the nearest whole number) in an amount equal to (a) the number of TransGlobe common shares underlying such DSUs, RSUs or PSUs, multiplied by (b) the exchange ratio. For the PSUs that will remain outstanding following the effective time as described in the immediately preceding sentence, the applicable vesting percentage will be determined by the TransGlobe board of directors, which percentage will not exceed 200%.

Dissent Shares

Registered TransGlobe shareholders may exercise rights of dissent with respect to the TransGlobe common shares held by such TransGlobe shareholders pursuant to Section 191 of the ABCA, as modified by the Court’s interim order, final order and the plan of arrangement.

None of the following will be entitled to exercise dissent rights: (i) TransGlobe shareholders who vote or have instructed a proxyholder to vote their TransGlobe common shares in favor of the TransGlobe resolution (but only in respect of such TransGlobe common shares); (ii) holders of TransGlobe options, DSUs, PSUs and RSUs; and (iii) any other person who is not a registered holder of TransGlobe common shares as of the record date for TransGlobe’s shareholder meeting to be held in connection with the arrangement. A TransGlobe shareholder may only exercise its dissent rights in respect of all, and not less than all, of its TransGlobe common shares.

Surrender of Shares

VAALCO and TransGlobe have appointed Computershare Investor Services Inc. to act as depositary to handle the exchange of TransGlobe common shares for shares of VAALCO common stock. Following receipt by TransGlobe of the Court’s final order and prior to the effective time, VAALCO and AcquireCo will deliver or cause to be

TABLE OF CONTENTS

delivered to the depositary such number of shares of VAALCO common stock to satisfy the aggregate consideration payable to TransGlobe shareholders in accordance with the plan of arrangement which shares of VAALCO common stock will be held by the depositary as agent and nominee for such former TransGlobe shareholders for distribution to them in accordance with the plan of arrangement.

Upon surrender to the depositary for cancellation of a certificate which immediately prior to the effective time represented outstanding TransGlobe common shares that were transferred pursuant to the plan of arrangement, together with a duly completed and executed letter of transmittal and any such additional documents and instruments as the depositary may reasonably require, the registered holder of such TransGlobe common shares represented by such surrendered certificate will be entitled to receive the corresponding consideration shares less any amounts withheld pursuant to the plan of arrangement and any certificate so surrendered will be cancelled.

After the effective time and until surrendered for cancellation, each certificate that immediately prior to the effective time represented one or more outstanding TransGlobe common shares (other than TransGlobe common shares held by VAALCO, AcquireCo or any of their affiliates) will be deemed at all times to represent only the right to receive in exchange therefor the consideration that the holder of such certificate is entitled to receive in accordance with the plan of arrangement.

Lost Certificates

In the event any certificate which immediately prior to the effective time represented one or more TransGlobe common shares (excluding shares held by VAALCO, AcquireCo or any of their respective affiliates or by shareholders that validly exercise, and do not withdraw, their dissent rights) is lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such certificate to be lost, stolen or destroyed, the depositary will issue in exchange for such lost, stolen or destroyed certificate, the consideration deliverable in accordance with such holder’s duly completed and executed letter of transmittal. When authorizing such consideration shares in exchange for any lost, stolen or destroyed certificate, the person to whom such consideration is to be delivered shall, as a condition precedent to the delivery of such consideration, give a bond satisfactory to VAALCO, TransGlobe and the depositary (acting reasonably) in such sum as VAALCO may direct, or otherwise indemnify VAALCO, AcquireCo and TransGlobe in a manner satisfactory to VAALCO and TransGlobe, each acting reasonably, against any claim that may be made against VAALCO, AcquireCo and TransGlobe with respect to the certificate alleged to have been lost, stolen or destroyed.

Cancellation of Rights After Three Years

To the extent that a former TransGlobe shareholder has not complied with the provisions of the plan of arrangement in respect of certificates and payments and/or lost certificates, on or before the date that is the last business day prior to the third anniversary of the effective date (the “final proscription date”), then the consideration shares that such former TransGlobe shareholder was entitled to receive will be automatically cancelled without any repayment of capital in respect thereof and the consideration shares to which such former TransGlobe shareholder was entitled, will be delivered to VAALCO by the depositary and the shares of VAALCO common stock forming part of the consideration shares will be deemed to be cancelled, and the interest of the former TransGlobe shareholder in such shares (including any dividend or other distributions) to which such TransGlobe shareholder was entitled will be terminated as of such final proscription date, and the certificates formerly representing TransGlobe common shares will cease to represent a right or claim of any kind or nature as of such final proscription date. Any payment made by way of cheque by the depositary pursuant to the plan of arrangement that has not been deposited or has been returned to the depositary or that otherwise remains unclaimed, in each case, on or before the final proscription date will cease to represent a right or claim of any kind or nature and the right of any TransGlobe shareholder to receive the consideration shares pursuant to the plan of arrangement will terminate and be deemed to be surrendered and forfeited to VAALCO.

Efforts to Obtain Required TransGlobe Shareholder Approval

The arrangement agreement requires TransGlobe to use commercially reasonable efforts to schedule TransGlobe’s shareholder meeting on the same date as the special meeting.

In general, TransGlobe is not permitted to adjourn, postpone or cancel (or propose or permit the adjournment, postponement or cancellation of) TransGlobe’s shareholder meeting without VAALCO’s prior written consent except

TABLE OF CONTENTS

as required for quorum purposes (in which case the meeting will be adjourned and not cancelled), by law, by a governmental entity or by valid TransGlobe shareholder action (which action is not solicited or proposed by TransGlobe or the TransGlobe board of directors).

Unless the TransGlobe board of directors has modified its recommendation regarding the arrangement as permitted under the arrangement agreement, as further discussed in “Non-Solicitation Covenants” below, TransGlobe will include in its circular (i) a copy of the Court’s interim order; (ii) a copy of the fairness opinion provided by TransGlobe’s financial advisor; (iii) a statement that the TransGlobe board of directors has received the fairness opinion provided by its financial advisor and has unanimously determined, after receiving legal and financial advice, that the arrangement is fair to TransGlobe shareholders and that the arrangement and entry into the arrangement agreement are in the best interests of TransGlobe; (iv) the unanimous recommendation of the TransGlobe board of directors to the TransGlobe shareholders that they vote in favor of the TransGlobe resolution; and (v) statements that each of the TransGlobe shareholders that have entered into support and voting agreements will vote their TransGlobe common shares in favor of the TransGlobe resolution.

Efforts to Obtain Required VAALCO Stockholder Approval

VAALCO is required to use commercially reasonable efforts to schedule the special meeting as promptly as reasonably practicable following SEC clearance of this proxy statement and on the same date as TransGlobe’s shareholder meeting.

In general, VAALCO is not permitted to adjourn, postpone or cancel (or propose or permit the adjournment, postponement or cancellation of) the special meeting without TransGlobe’s prior written consent except as required for quorum purposes (in which case the meeting will be adjourned and not cancelled), by law, by a governmental entity or by valid VAALCO stockholder action (which action is not solicited or proposed by VAALCO or the VAALCO board of directors).

Unless the VAALCO board of directors has modified its recommendation regarding the arrangement as permitted under the arrangement agreement, as further discussed in “Non-Solicitation Covenants” below, VAALCO will include in its proxy statement: (i) a copy of the fairness opinion provided by VAALCO’s financial advisor (ii) a statement that the VAALCO board of directors has received such fairness opinion and has unanimously determined, after receiving legal and financial advice, that the arrangement and entry into the arrangement agreement are in the best interests of VAALCO, (iii) the unanimous recommendation of the VAALCO board of directors to the VAALCO stockholders that they vote in favor of the amendment proposal and the share issuance proposal and (iv) statements that each of the VAALCO stockholders that entered into support and voting agreements will vote their VAALCO common stock in favor of the amendment proposal and the share issuance proposal.

Final Court Approval

After the interim order of the Court has been obtained and the TransGlobe shareholders have approved the arrangement, TransGlobe is required to seek the final approval of the arrangement by the Court as soon as reasonably practicable, but in any event not later than five business days thereafter unless the Court operations are restricted in response to any COVID-19 measures. The Court will consider, among other things, the procedural and substantive fairness of the terms and conditions of the arrangement to the TransGlobe shareholders.

Corporate Governance

Pursuant to the arrangement agreement, VAALCO is required to take all actions necessary to ensure that as of the effective time the board of directors of VAALCO will consist of: (i) the four existing members of the VAALCO board of directors: Andrew L. Fawthrop, George Maxwell, Cathy Stubbs and Fabrice Nze-Bekale; and (ii) three of the members of TransGlobe’s existing board of directors: David Cook, Edward LaFehr and Timothy Marchant. Andrew L.

VAALCO will use all commercially reasonable efforts to cause its current insurance (or re-insurance) policies maintained by VAALCO or any of its subsidiaries not to be cancelled or terminated or any of the coverage thereunder to lapse, unless simultaneously with such termination, cancellation or lapse, replacement policies underwritten by insurance and reinsurance companies of nationally recognized standing providing coverage equal to or greater than the coverage under the cancelled, terminated or lapsed policies for substantially similar premiums are in full force and effect.

VAALCO has agreed that it will not authorize, agree to, propose, enter into or modify any contract to do any of the matters prohibited by the arrangement agreement or resolve to do so; provided, however, that VAALCO may enter into, engage in, continue or otherwise participate in any discussions or negotiations with any person regarding the acquisition of such person or the purchase of any property or assets from any other person.

Mutual Covenants Regarding Takeover Laws

Each of TransGlobe, VAALCO and AcquireCo has agreed that it and its board of directors will approve and take all reasonably necessary or appropriate actions (i) to ensure that no takeover law prohibits or impairs consummation of the transactions contemplated in the arrangement agreement; and (ii) if there is any takeover law prohibiting or impairing the consummation of the transactions contemplated in the arrangement agreement, to ensure that the arrangement may be consummated as promptly as practicable pursuant to the terms of the arrangement agreement and to otherwise act reasonably to eliminate or minimize the effects of such takeover law on the transactions contemplated by the arrangement agreement.

Mutual Covenants Relating to the Arrangement

Each of TransGlobe, VAALCO and AcquireCo has agreed that, other than in connection with the condition to closing described in the fourth bullet of the second paragraph under “Conditions to Completion of the Arrangement,” subject to the terms and conditions of the arrangement agreement, during the period from the date of the arrangement agreement until the earlier of the effective time and the time the arrangement agreement is terminated in accordance with its terms:

•

it will use its commercially reasonable efforts to, and will cause its subsidiaries to use all commercially reasonable efforts to, satisfy (or cause the satisfaction of) the conditions precedent to its obligations thereunder as set forth in the arrangement agreement to the extent the same is within its control and to take, or cause to be taken, all other action and do, or cause to be done, all other things necessary, proper or advisable under all applicable laws to complete the arrangement, including using its commercially reasonable efforts to promptly: (i) obtain all necessary waivers, consents, and approvals required to be obtained by it from parties to TransGlobe’s material contracts (as such term is defined in the arrangement agreement) or VAALCO’s material contracts, as the case may be; (ii) obtain all necessary and material authorizations as are required to be obtained by it or any of its subsidiaries under applicable laws; (iii) fulfill all conditions and satisfy all provisions of the arrangement agreement, including delivery of certificates of their respective officers contemplated by the arrangement agreement; and (iv) co-operate with the other party in connection with the performance by it and its subsidiaries of their obligations under the arrangement agreement;

•

it will not take any action, will refrain from taking any action, and will not permit any action to be taken or not taken, which would reasonably be expected to, individually or in the aggregate, prevent, materially impede or materially delay the consummation of the arrangement or the other transactions contemplated in the arrangement agreement;

•

it will use commercially reasonable efforts to: (i) defend all lawsuits or other legal, regulatory or other proceedings against itself or any of its subsidiaries challenging or affecting the arrangement agreement or the consummation of the transactions contemplated in the arrangement agreement, (ii) appeal, overturn or have lifted or rescinded any injunction or restraining order or other order relating to itself or any of its subsidiaries which may materially adversely affect the ability of the parties to consummate the arrangement, and (iii) appeal or overturn or otherwise have lifted or rendered non-applicable in respect of the arrangement, any law that makes consummating the arrangement illegal or otherwise prohibits or enjoins TransGlobe, VAALCO or AcquireCo from consummating the arrangement; and

Treatment of TransGlobe Awards

Each of TransGlobe, VAALCO, AcquireCo and the TransGlobe board of directors (and any relevant committee thereof), will take such actions (including all actions permitted under the TransGlobe Equity Incentive Plans (as defined in the arrangement agreement) as are necessary, such that, from and after the effective time (i) each TransGlobe option, DSU, PSU and RSU (collectively, the “TransGlobe awards”)) in each case that is outstanding as of immediately prior to the effective time, will be dealt with as provided in the plan of arrangement; and (ii) notwithstanding any provision herein to the contrary, at or prior to the effective time, TransGlobe, its board of directors, the Compensation, Human Resources and Governance Committee of the TransGlobe board of directors, as applicable, will adopt any resolutions and take all actions that are necessary to effectuate the provisions of the arrangement agreement and the plan of arrangement related to the TransGlobe awards.

Non-Solicitation of Alternative Transactions and Change in Recommendation

Each of TransGlobe and VAALCO has agreed not to and to cause their respective subsidiaries and their respective directors, officers and employees not to, and to use its reasonable best efforts to cause their respective representatives not to:

•

•	accept or enter into, or publicly propose to accept or enter into, any letter of intent, agreement in principle, agreement, arrangement or undertaking relating to any acquisition proposal (other than a confidentiality agreement pursuant to certain provisions of the arrangement agreement);

•

(i) modify or qualify in any manner adverse to (or publicly propose to do so) the other party, or withdraw, its board recommendation; (ii) make any approval, endorsement or recommendation (or publicly propose to do so) by its board of any tender offer, take-over bid or other acquisition proposal (other than a recommendation against such offer, bid or acquisition proposal); (iii) fail to include their respective board recommendation in the proxy statement or proxy circular, as the case may be; (iv) fail to publicly reaffirm its board recommendation within five business days after the other party reasonably requests in writing after a material event or development (other than an event described in clause (v) below) (or within such fewer number of days as remains before the day that is two business days before the special meeting or TransGlobe’s shareholder meeting, as applicable); (v) (x) as to VAALCO, fail to recommend, in a solicitation/recommendation statement on Schedule 14D-9 against any acquisition proposal that is a tender offer or exchange offer subject to Regulation 14D promulgated under the Exchange Act within 10 business days after commencement of such tender offer or exchange offer, or (y) as to TransGlobe, in the case of a take-over bid subject to National Instrument 62-104 - Takeover Bids and Issuer Bids, fail to unanimously (subject to abstentions of any conflicted director) recommend, in a directors’ circular, rejection of such take-over bid within 15 days of the date of such take-over bid; or (vi) take no position or a neutral position with respect to an acquisition proposal for more than five business days after the public announcement of such acquisition proposal (it being understood that taking no position or a neutral position with respect to an acquisition proposal for a period of no more than five business days after the public announcement of such acquisition proposal will not be considered to be a change in recommendation provided (other than with respect to an event described in clause (v)(x) above as to VAALCO), the relevant board of directors has rejected such acquisition proposal and reaffirmed its board recommendation before the end of such five business day period); or

108

TABLE OF CONTENTS

•	make any public announcement or take any other action inconsistent with the approval, recommendation or declaration of advisability of the board of directors of the transactions contemplated in the arrangement agreement.

Each of TransGlobe and VAALCO has agreed that it will, and will cause its respective subsidiaries and representatives to, immediately cease any solicitation, discussions, negotiations or other activities commenced prior to the date of the arrangement agreement with any person (other than the other party and its subsidiaries or affiliates) conducted by such party or such party’s subsidiaries or representatives with respect to any inquiry, proposal or offer that constitutes, or may reasonably be expected to constitute or lead to, an acquisition proposal, and in connection therewith, such party will discontinue access to and disclosure of its and its subsidiaries’ confidential information (and not allow access to or disclosure of any such confidential information, or any data room, virtual or otherwise) and will as soon as practicable (and in any event within 24 hours) request, and use its commercially reasonable efforts to exercise all rights it has (or cause its subsidiaries to exercise any rights that they have) to require the return or destruction of all confidential information regarding such party and its subsidiaries previously provided in connection therewith to any person other than the other party to the extent such information has not already been returned or destroyed and use commercially reasonable efforts to ensure that such obligations are fulfilled.

Each of TransGlobe and VAALCO has represented and warranted as of the date of the arrangement agreement that neither it nor any of its subsidiaries has waived any standstill, confidentiality, non-disclosure, business purpose, use or similar agreement or restriction to which such party or any of its subsidiaries is a party, except to permit submissions of expressions of interest prior to the date of the arrangement agreement. Each of TransGlobe and VAALCO has covenanted and agreed that (i) it will enforce each standstill, confidentiality, non-disclosure, business purpose, use or similar agreement or restriction to which such party or any of its subsidiaries is a party, and (ii) neither it nor any of its subsidiaries nor any of their respective representatives has (within the last 12 months) or will, without the prior written consent of the other party (which may be withheld or delayed in the other party’s sole and absolute discretion), release any person from, or waive, amend, suspend or otherwise modify such person’s obligations respecting either VAALCO or TransGlobe, as the case may be, or any of its subsidiaries, under any standstill, confidentiality, non-disclosure, business purpose, use or similar agreement or restriction to which either VAALCO or TransGlobe, as the case may be, or any of its subsidiaries is a party; provided, however, that TransGlobe, VAALCO and AcquireCo acknowledge and agree that the automatic termination or release of any such standstill, confidentiality, non-disclosure, business purpose, use or similar agreement or restriction in accordance with its terms will not be a breach of the arrangement agreement.

Each of TransGlobe and VAALCO will as soon as practicable, and in any event, within 24 hours, notify the other party (orally at first and then in writing, in each case within 24 hours) if it receives or otherwise becomes aware of any inquiry, proposal or offer that constitutes or would reasonably be expected to constitute or lead to an acquisition proposal, of such acquisition proposal, inquiry, proposal or offer, including the identity of the person making such acquisition proposal, inquiry, proposal or offer and the material terms and conditions thereof and unredacted copies of all material or substantive documents or correspondence received in respect of, from or on behalf of any such person. Each of TransGlobe and VAALCO will keep the other party promptly and fully informed of the material developments and discussions and negotiations with respect to any such acquisition proposal, inquiry, proposal or offer, including any material changes, modifications or other amendments thereto.

Notwithstanding any other provision of the arrangement agreement, if, at any time after the date of the arrangement agreement and prior to a party obtaining the approval of its stockholders or shareholders, as applicable, TransGlobe or VAALCO receives a request for material non-public information or to enter into discussions, from a person that proposes to such party an unsolicited bona fide written acquisition proposal that did not result from a breach of the non-solicitation covenants in the arrangement agreement (and which has not been withdrawn) and such party’s board of directors determines, in good faith after consultation with its outside financial and legal advisors, that such acquisition proposal constitutes or would reasonably be expected to constitute a superior proposal (disregarding, for the purposes of such determination, any due diligence or access condition to which such acquisition proposal is subject), then, and only in such case, such party may (i) enter into, participate in, facilitate and maintain discussions or negotiations with, and otherwise cooperate with or assist, the person making such acquisition proposal, and (ii) provide the person making such acquisition proposal with, or access to, confidential information regarding such party and its subsidiaries, but only to the extent that the other party had previously been, or is concurrently, provided with, or access to, the same information, if, and only if: (x) such party has entered into a confidentiality agreement on terms no less favorable in aggregate to such party than the confidentiality agreement entered into between

109

TABLE OF CONTENTS

TransGlobe and VAALCO in connection with the arrangement agreement (provided such confidentiality agreement will not be required to have any standstill provisions), a copy of which must be provided to the other party promptly and in any event prior to providing such person with any such copies, access or disclosure, and provided further that such confidentiality agreement will not contain any exclusivity provision or other term that would restrict, in any manner, such party’s ability to consummate the transactions contemplated in the arrangement agreement or to comply with its disclosure obligations to the other party pursuant to the arrangement agreement, and any such copies, access or disclosure provided to such person will have already been, or will substantially concurrently be, provided to the other party; (y) the person submitting the acquisition proposal was not restricted from making such acquisition proposal pursuant to an existing confidentiality, standstill, non-disclosure, use, business purpose or similar agreement, restriction or covenant with such party or any of its subsidiaries; and (z) such party has been, and continues to be, in material compliance with its non-solicitation covenants in the arrangement agreement.

TransGlobe and VAALCO have agreed that notwithstanding any other provision of the arrangement agreement, neither TransGlobe nor VAALCO will make a change in recommendation in connection with an acquisition proposal unless all of the following conditions are satisfied: (i) the board of directors of such party has determined that the acquisition proposal constitutes a superior proposal; (ii) stockholder approval or shareholder approval, as applicable, has not been obtained; (iii) such party has been, and continues to be, in material compliance with its non-solicitation covenants in the arrangement agreement; (iv) such party has promptly provided the other party with a notice in writing that there is a superior proposal, together with all documentation related to and detailing the superior proposal, including a copy of any proposed agreement and all ancillary documentation relating to such superior proposal as well as the cash value that such party’s board of directors has, after consultation with outside financial advisors, determined should be ascribed to any non-cash consideration offered under the superior proposal; (v) five business days (the “response period”) has elapsed from the date the other party received the notice and documentation referred to in the immediately preceding clause (iv) from such party; and (vi) if the other party has proposed to amend the terms of the arrangement in accordance with the arrangement agreement, the board of directors of the party that received the proposal would have determined, in good faith, after consultation with its outside financial and legal advisors, that the acquisition proposal remains a superior proposal compared to the proposed amendment to the terms of the arrangement by the other party, if applicable.

For greater certainty, notwithstanding any change in recommendation, unless the arrangement agreement has been terminated in accordance with its terms, the party whose board of directors changed its recommendation must still hold its stockholder or shareholder meeting, as applicable, and allow its stockholders or shareholders, as applicable, to vote on the arrangement, and such party is not permitted, except in accordance with the arrangement agreement, and such party will not, except as required by applicable law, submit to a vote of its stockholders or shareholders, as applicable, any acquisition proposal other than the arrangement prior to the termination of the arrangement agreement.

Each of TransGlobe and VAALCO has acknowledged and agreed that, during the response period or such longer period as the party that received the acquisition proposal approved for such purpose, the other party will have the opportunity, but not the obligation, to propose to amend the terms of the arrangement agreement, including a modification of the consideration. The board of directors of the party that received the acquisition proposal will review any such proposal to determine in good faith whether the other party’s proposal to amend the arrangement agreement would result in the acquisition proposal ceasing to be a superior proposal. If the board of directors of the party that received the acquisition proposal determines that the acquisition proposal is not a superior proposal as compared to the proposed amendments to the terms of the arrangement agreement, it will promptly advise the other party and enter into an amended agreement with the other party reflecting such proposed amendments. If the board of directors of the party that received the acquisition proposal continues to believe in good faith, after consultation with its financial advisors and outside legal counsel, that such acquisition proposal remains a superior proposal and therefore rejects the other party’s offer to amend the arrangement agreement and the arrangement, if any, the party that received the acquisition proposal may, subject to compliance with the other provisions hereof, make a change in recommendation. Each successive modification of any acquisition proposal will constitute a new acquisition proposal for purposes of the arrangement agreement and the other party will be afforded a new response period in respect of each such acquisition proposal from the date on which the other party received the notice and documentation referred to in the preceding paragraph in respect of such new superior proposal from the party that received the acquisition proposal.

110

TABLE OF CONTENTS

The board of directors of the party that received the acquisition proposal will promptly reaffirm its board recommendation by press release after: (i) the board of directors of such party determines any acquisition proposal that has been publicly announced or publicly disclosed is not a superior proposal; or (ii) the board of directors of such party determines that a proposed amendment to the terms of the arrangement would result in any acquisition proposal which has been publicly announced or made not being a superior proposal.

Notwithstanding the foregoing, each of TransGlobe and VAALCO may effect a change in recommendation in response to an intervening event (as defined below) if and only if all of the following are satisfied: (i) such party’s board of directors will have determined in good faith (after consultation with its outside legal counsel) that the failure to effect a change in recommendation in response to such intervening event would be inconsistent with its fiduciary duties under applicable law; (ii) the stockholder or shareholder approval, as applicable, with respect to such party has not been obtained; (iii) such party has promptly provided the other party with a notice in writing that it intends to effect a change in recommendation in response to an intervening event, describing in reasonable detail the underlying facts giving rise to, and the reasons for making, such change in recommendation (it being understood that such notice will not constitute a change in recommendation for purposes of the arrangement agreement); (iv) five business days (the “intervening event response period”) have elapsed from the date the other party received the notice referred to in clause (iii); and (v) if the other party has proposed to amend the terms of the arrangement, the board of directors of the party that has experienced an intervening event has determined after complying with its obligations under the following paragraph, in good faith, after consultation with its outside legal advisors, that the failure to effect a change in recommendation in response to such intervening event would be inconsistent with its fiduciary duties under applicable law.

Each of TransGlobe and VAALCO has acknowledged and agreed that, during an intervening event response period or such longer period as the party considering the change in recommendation may approve for such purpose, the other party will have the opportunity, but not the obligation, to propose to amend the terms of the arrangement agreement, including an increase in, or modification of, the consideration. The board of directors of the party that has experienced an intervening event will review any such proposal to determine in good faith whether the other party’s proposal to amend the arrangement agreement would obviate the need to effect a change in recommendation in response to the intervening event. If the board of directors of the party that has experienced an intervening event determines that it need not effect a change in recommendation in response to the intervening event in light of the proposed amendments to the terms of the arrangement agreement, it will promptly advise the other party and enter into an amended agreement reflecting such proposed amendments. If the board of directors of the party that has experienced an intervening event continues to believe in good faith, after consultation with its outside legal counsel, that the failure to effect a change in recommendation in response to such intervening event would be inconsistent with its fiduciary duties under applicable law and therefore rejects the other party’s offer to amend the arrangement agreement and the arrangement, if any, the party that has experienced an intervening event, subject to compliance with the other provisions of the arrangement agreement, make a change in recommendation.

In circumstances where either TransGlobe or VAALCO provides the other party with notice of a superior proposal and all documentation contemplated by the arrangement agreement or a notice contemplated by the arrangement agreement, in each case, on a date that is less than seven business days prior to TransGlobe’s shareholder meeting or the special meeting, as applicable, the party providing the notice may, or if and as requested by the other party, such party must, either proceed with or postpone TransGlobe’s shareholder meeting or the special meeting, as applicable, to a date that is not more than seven business days after the scheduled date of such meeting, as directed by the other party, provided, however, that TransGlobe’s shareholder meeting or the special meeting, as applicable, will not be adjourned or postponed to a date later than the fifth business day prior to the outside date.

Without limiting the generality of the foregoing, each of TransGlobe and VAALCO will advise its subsidiaries and its representatives of the prohibitions set out in the arrangement agreement and any violation of the restrictions set forth therein by either party, its subsidiaries or representatives is deemed to be a breach of the arrangement agreement by such party.

Nothing contained in the non-solicit provisions of the arrangement agreement will prohibit (A) VAALCO and its board of directors or a committee thereof from (i) taking and disclosing to VAALCO stockholders a position contemplated by Rule 14e-2(a) or Rule 14d-9 promulgated under the Exchange Act, (ii) making any disclosure to VAALCO stockholders that is required by law or stock exchange rule or listing agreement, (iii) complying with Item 1012(a) of Regulation M-A promulgated under the Exchange Act or (iv) making any “stop, look and listen” communication to VAALCO stockholders pursuant to Rule 14d 9(f) under the Exchange Act (or any substantially

111

TABLE OF CONTENTS

similar communication) or (B) TransGlobe and its board of directors or a committee thereof from making any disclosure to the TransGlobe shareholders that is required by law or stock exchange rule or listing agreement; provided, however, that (x) each party will provide the other party and its external legal counsel with a reasonable opportunity to review and comment on the form and content of any such disclosure and will give reasonable consideration to such comments, and (y) the arrangement agreement will not be deemed to permit either party’s board of directors to make a change in recommendation other than in accordance with the applicable provisions of the arrangement agreement.

An “acquisition proposal” is, other than the transactions contemplated by the arrangement agreement and as disclosed in TransGlobe’s or VAALCO’s disclosure letter, as applicable, and other than any transaction involving only such party and/or one or more of its wholly-owned subsidiaries, any offer, proposal, expression of interest or inquiry from, or public announcement of intention by, any person or group of persons (other than the other party or any of its affiliates) relating to:

•

any acquisition or purchase (or any lease, royalty, agreement, joint venture, long-term supply agreement or other arrangement having the same economic effect as an acquisition or purchase), direct or indirect, through one or more transactions, of (i) the assets of TransGlobe or VAALCO, as applicable, and/or one or more of its subsidiaries that, individually or in the aggregate, constitute 20% or more of the consolidated assets of such party and its subsidiaries, taken as a whole, or which contribute 20% or more of the consolidated revenue of such party and its subsidiaries, taken as a whole; or (ii) 20% or more of any voting or equity securities of TransGlobe or VAALCO, as applicable, or 20% or more of any voting or equity securities of any one or more of any of such party’s subsidiaries that, individually or in the aggregate, contribute 20% or more of the consolidated revenues or constitute 20% or more of the consolidated assets of such party and its subsidiaries, taken as a whole;

•

any direct or indirect take-over bid, tender offer, exchange offer, treasury issuance or other transaction that, if consummated, would result in such person or group of persons beneficially owning 20% or more of any class of voting or equity securities (and/or securities convertible into, or exchangeable or exercisable for voting or equity securities) of TransGlobe or VAALCO, as applicable;

•

a plan of arrangement, merger, amalgamation, consolidation, share exchange, share reclassification, business combination, reorganization, recapitalization, liquidation, dissolution, winding up or other similar transaction or series of transactions involving TransGlobe or VAALCO, as applicable, or any of its subsidiaries that, if consummated, individually or in the aggregate, would result in such person or group of persons beneficially owning 20% or more of the consolidated assets of such party and its subsidiaries, taken as a whole, or which contribute 20% or more of the consolidated revenue of such party and its subsidiaries, taken as a whole;

•

in the case of TransGlobe, any transaction that would comprise a “substantial transaction” for the purposes of rule 12 of the AIM Rules (provided that for the purposes of determining whether a particular transaction is “substantial,” only the consideration test in Schedule 3 of the AIM Rules will be used); or

•

any other transaction, the consummation of which would materially impede, interfere with or delay, or prevent, the transactions contemplated by the arrangement agreement or the arrangement or which would reasonably be expected to materially reduce the benefits to TransGlobe or VAALCO, as applicable, of the arrangement.

A “superior proposal” is an unsolicited bona fide written acquisition proposal from a person or persons who is or are, as at the date of the arrangement agreement, a party that deals at arm’s length with the party receiving the acquisition proposal, that is not obtained in violation of the arrangement agreement, or any agreement between the person making such superior proposal and such party, to acquire 100% of the outstanding stock or shares of such party (other than the stock or shares beneficially owned by the person or persons making such superior proposal) or all or substantially all of the assets of such party and its subsidiaries on a consolidated basis made after the date of the arrangement agreement and:

•	is not subject to any financing condition and in respect of which any required financing to complete such acquisition proposal has been demonstrated to be available to the satisfaction of such party’s board of directors, acting in good faith;

•	is not subject to a due diligence and/or access condition;

112

TABLE OF CONTENTS

•	is reasonably capable of being consummated without undue delay, taking into account all legal, financial, regulatory and other aspects of such acquisition proposal and the person making such acquisition proposal; and

•

such party’s board of directors determines in good faith, after consultation with its outside financial and legal advisors, and after taking into account all the terms and conditions of such acquisition proposal and all factors and matters considered appropriate in good faith by such party’s board of directors, would, if consummated in accordance with its terms (but not assuming away any risk of non-completion), result in a transaction that is more favorable, from a financial point of view, to such party’s stockholders or shareholders, as applicable, than the arrangement (including any adjustment to the terms and conditions of the arrangement proposed by the other party pursuant to the arrangement agreement).

An “intervening event” means any fact, event, change, occurrence, effect or state of facts, that is material to either TransGlobe or VAALCO, as applicable, and its subsidiaries, taken as a whole, that is not actually known or reasonably foreseeable by such party’s board of directors as of the date of the arrangement agreement (or if known or reasonably foreseeable, the material consequences of which were not known or reasonably foreseeable by the board of directors as of the date of the arrangement agreement) and does not relate to (i) an acquisition proposal or any inquiry that constitutes, or would reasonably be expected to lead to, an acquisition proposal; (ii) changes in the market price or trading volume of such party’s shares in and of themselves; or (iii) the fact, in and of itself, that such party meets, exceeds, or fails to meet in any quantifiable respect, any internal or analyst’s projections, guidance, expectations, forecasts or estimates for any period or that such party’s credit rating has changed.

Pre-Acquisition Reorganization

Subject to the paragraph below, TransGlobe has agreed that, at VAALCO’s reasonable request, TransGlobe will use commercially reasonable efforts to (i) perform such reorganizations of the corporate structure, capital structure, business, operations and assets of TransGlobe or its subsidiaries or such other transactions as VAALCO may request prior to the effective date of the arrangement agreement, acting reasonably, and the plan of arrangement, if required, will be modified accordingly, and (ii) to cooperate with VAALCO and its advisors to determine the nature of the reorganizations that might be undertaken and the manner in which they would most effectively be undertaken.

TransGlobe and its subsidiaries will not be obligated to participate in any such pre-acquisition reorganization unless such pre-acquisition reorganization, in the opinion of TransGlobe, acting reasonably: (i) cannot reasonably be expected to result in any taxes being imposed on, or any adverse tax consequences to TransGlobe shareholders incrementally greater than the taxes to such party in connection with the consummation of the arrangement absent any pre-acquisition reorganization; (ii) is not prejudicial to TransGlobe or its shareholders in any material respect; (iii) does not require TransGlobe to obtain the approval of securityholders of TransGlobe or proceed absent any required consent of any third party; (iv) does not unreasonably interfere with TransGlobe’s material operations prior to the effective time; (v) does not require TransGlobe or its subsidiaries to contravene any contract, authorization (as such terms are defined in the arrangement agreement) or applicable laws, or its organizational documents; (vi) is effected as close as reasonably practicable prior to the effective time, and in any case, no earlier than one business day prior to the effective date; and (vii) does not impair the ability of TransGlobe to consummate, and will not prevent or materially delay the consummation of, the arrangement.

Unless the arrangement is not completed due to a breach by TransGlobe of the terms and conditions of the arrangement agreement or in circumstances that would give rise to the payment by TransGlobe of a termination fee, VAALCO (or, at VAALCO’s direction, AcquireCo) has agreed that it will be responsible for all reasonable costs and expenses associated with any such pre-acquisition reorganization.

Financing Cooperation

TransGlobe has agreed to use commercially reasonable efforts to provide, and to cause each of its subsidiaries and each of their respective representatives to provide, such cooperation as may be reasonably requested by VAALCO in connection with the borrowing or an issuance of debt by VAALCO, AcquireCo and/or any liability management transaction (including, without limitation, any exchange offers, consent solicitations or tender offers) with respect to debt existing on the date of the arrangement agreement of TransGlobe or its subsidiaries (collectively, a “debt financing”), including, without limitation to, upon reasonable notice: (i) provide assistance with any discussions of and/or furnish, as applicable, such business, financial statements, pro forma financials, projections, management discussion and analysis and other customary financial data and information (including diligence

113

materials) reasonably required in connection with any debt financing, (ii) direct their respective independent accountants to provide customary and reasonable assistance in connection with any debt financing, including in connection with providing customary comfort letters and consents, (iii) obtain customary payoff letters, releases of liens and other instruments of termination or discharge reasonably requested by VAALCO in connection with the repayment of debt of TransGlobe and its subsidiaries (provided that the effectiveness of any such arrangements will be contingent on the completion of the arrangement) and (iv) authorize and facilitate discussions, meetings and other engagement by VAALCO, its subsidiaries or affiliates with the current lenders, noteholders or other providers of existing indebtedness to TransGlobe or any of its subsidiaries for the purpose of obtaining debt financing, including by necessary or appropriate waivers of the confidentiality agreement to permit such activities. VAALCO (or, at VAALCO’s direction, AcquireCo) will reimburse TransGlobe for all reasonable out-of-pocket costs or expenses incurred by TransGlobe and its subsidiaries in connection with cooperation provided for in the arrangement agreement to the extent the information requested was not otherwise prepared or available in the ordinary course of business.

VAALCO has agreed that the consummation of the transactions contemplated by the arrangement agreement is not conditioned upon the consummation of, or the receipt by VAALCO or AcquireCo of the proceeds of, the debt financing.

Other Covenants and Agreements

The arrangement agreement contains certain other covenants and agreements, including covenants relating to:

•	cooperation between TransGlobe and VAALCO in connection with public announcements and communications;

TABLE OF CONTENTS

PROPOSAL NO. 1 – THE AMENDMENT PROPOSAL

The increase in the number of authorized shares of VAALCO common stock in the VAALCO Certificate of Incorporation is intended to permit the issuance of a sufficient number of shares of common stock, to be issued as consideration shares in connection with the arrangement.

The arrangement agreement requires that VAALCO issue and deliver to TransGlobe shareholders the consideration shares which are approximately 49.3 million shares of VAALCO common stock. In order to issue the consideration shares to TransGlobe shareholders in connection with the arrangement, it is necessary to amend the VAALCO Certificate of Incorporation to increase the amount of authorized capital stock from 100,500,000 shares, divided into 100,000,000 shares of VAALCO common stock and 500,000 shares of VAALCO preferred stock, to 160,500,000 shares, divided into 160,000,000 shares of VAALCO common stock and 500,000 shares of VAALCO preferred stock. The VAALCO board of directors has unanimously adopted resolutions approving and declaring advisable, and recommending that our stockholders adopt, the Amendment to VAALCO Certificate of Incorporation. This summary of the proposed amendment is qualified in its entirety by reference to the text of the proposed amendment to the VAALCO Certificate of Incorporation attached as Annex E to this proxy statement, with deletions indicated by strike outs and additions indicated by double underlining.

This Proposal No. 1 – The Amendment Proposal and Proposal No. 2 – The Share Issuance Proposal are conditioned upon each other. Adoption by VAALCO stockholders of the amendment proposal is a condition to the closing of the arrangement and is necessary for VAALCO to issue the common stock to TransGlobe at the closing. Accordingly, if this Proposal No. 1 – The Amendment Proposal is not adopted at the special meeting, a condition to the closing of the arrangement will not be satisfied and the arrangement will not be completed.

Required Vote

Assuming the presence of a quorum, approval of this proposal requires the affirmative vote of the holders of a majority of the outstanding shares of VAALCO common stock entitled to vote at the special meeting. An abstention from voting on the amendment proposal will have the same effect as voting against the amendment proposal. A broker non-vote will not be voted on the amendment proposal.

Board Recommendation

The VAALCO board of directors unanimously recommends that you vote “FOR” this amendment proposal.

122

TABLE OF CONTENTS

PROPOSAL NO. 2 – THE SHARE ISSUANCE PROPOSAL

The VAALCO board of directors has unanimously adopted a resolution authorizing, approving, declaring advisable and recommending to VAALCO stockholders for their approval the issuance of shares of VAALCO common stock to TransGlobe shareholders in connection with the arrangement.

Section 312.03(c) of the NYSE Listed Company Manual requires prior to the issuance of common stock in any transaction if the number of shares of common stock to be issued is, or will be upon issuance, equal to or in excess of 20% of the number of shares of common stock outstanding before the issuance of the common stock. The number of shares of VAALCO common stock to be issued to TransGlobe shareholders as consideration for the arrangement will exceed 20% of the number of shares of VAALCO common stock outstanding before the issuance. Therefore, under Section 312.03(c) of the NYSE Listed Company Manual, stockholder approval of the share issuance proposal is required.

As of August 24, 2022, approximately 59.8 million shares of VAALCO common stock were issued and outstanding. Upon the consummation of the arrangement, TransGlobe shareholders would acquire an aggregate of up to approximately 49.3 million shares of VAALCO common stock, which represents approximately 82.4% of the shares of VAALCO common stock issued and outstanding prior to the consummation of the arrangement. Upon the consummation of the arrangement, TransGlobe shareholders would represent approximately 45.5% of the shares of the combined company, calculated based on VAALCO’s vested and outstanding shares and TransGlobe’s outstanding shares, each as of the date of the arrangement agreement.

Proposal No. 1 – The Amendment Proposal and this Proposal No. 2 – The Share Issuance Proposal are conditioned upon each other. Approval by VAALCO stockholders of the issuance of shares of VAALCO common stock to TransGlobe shareholders is a condition to the closing of the arrangement and is necessary for VAALCO to issue the common stock to TransGlobe at the closing. Accordingly, if this Proposal No. 2 – The Share Issuance Proposal is not approved at the special meeting, a condition to the closing of the arrangement will not be satisfied and the arrangement will not be completed.

Required Vote

Assuming the presence of a quorum, approval of this proposal requires the affirmative vote of the holders of a majority of the shares of VAALCO common stock who, being present in person (online) or voting by proxy and entitled to vote at the special meeting, cast votes affirmatively or negatively on the share issuance proposal. An abstention from voting on the share issuance proposal will have no effect on the outcome of the vote on this share issuance proposal. A broker non-vote will not be voted on the share issuance proposal.

Board Recommendation

The VAALCO board of directors unanimously recommends that you vote “FOR” this share issuance proposal.

2.17	Adjustment of Consideration

(a)

Notwithstanding anything in this Agreement to the contrary, if, between the date of this Agreement and the Effective Time, the issued and outstanding VAALCO Shares shall have been changed into a different number of shares by reason of any split or consolidation of the issued and outstanding VAALCO Shares, then the Consideration to be paid per TransGlobe Share shall be appropriately adjusted to provide to TransGlobe Shareholders the same economic effect as contemplated by this Agreement and the Arrangement prior to such action and as so adjusted shall, from and after the date of such event, be the Consideration to be paid per TransGlobe Share.

(b)

If on or after the date hereof, TransGlobe declares, sets aside or pays any dividend or other distribution to the TransGlobe Shareholders of record as of a time prior to the Effective Time, then the Consideration to be paid per TransGlobe Share shall be appropriately adjusted to provide to TransGlobe Shareholders the same economic effect as contemplated by this Agreement and the Arrangement prior to such action and as so adjusted shall, from and after the date of such event, be the Consideration to be paid per TransGlobe Share.

(d)

TransGlobe shall as soon as practicable, and in any event, within 24 hours, notify VAALCO (orally at first and then in writing, in each case within 24 hours) if it receives or otherwise becomes aware of any inquiry, proposal or offer that constitutes or would reasonably be expected to constitute or lead to a TransGlobe Acquisition Proposal, of such TransGlobe Acquisition Proposal, inquiry, proposal or offer, including the identity of the Person making such TransGlobe Acquisition Proposal, inquiry, proposal or offer and the material terms and conditions thereof and unredacted copies of all material or substantive documents or correspondence received in respect of, from or on behalf of any such Person. TransGlobe shall keep VAALCO promptly and fully informed of the material developments and discussions and negotiations with respect to such TransGlobe Acquisition Proposal, inquiry, proposal or offer, including any material changes, modifications or other amendments thereto.

result from a breach of this Section 5.8 (and which has not been withdrawn) and the TransGlobe Board determines, in good faith after consultation with its outside financial and legal advisors, that such TransGlobe Acquisition Proposal constitutes or would reasonably be expected to constitute a TransGlobe Superior Proposal (disregarding, for the purposes of such determination, any due diligence or access condition to which such TransGlobe Acquisition Proposal is subject), then, and only in such case, TransGlobe may (x) enter into, participate in, facilitate and maintain discussions or negotiations with, and otherwise cooperate with or assist, the Person making such TransGlobe Acquisition Proposal, and (y) provide the Person making such TransGlobe Acquisition Proposal with, or access to, confidential information regarding TransGlobe and its Subsidiaries, but only to the extent that VAALCO had previously been, or is concurrently, provided with, or access to, the same information, if, and only if:

(i)

TransGlobe has entered into a confidentiality agreement on terms no less favourable in aggregate to TransGlobe than the Confidentiality Agreement (provided such confidentiality agreement shall not be required to have any standstill provisions), a copy of which shall be provided to VAALCO promptly and in any event prior to providing such Person with any such copies, access or disclosure, and provided further that such confidentiality agreement will not contain any exclusivity provision or other term that would restrict, in any manner, TransGlobe’s ability to consummate the transactions contemplated hereby or to comply with its disclosure obligations to VAALCO and AcquireCo pursuant to this Agreement, and any such copies, access or disclosure provided to such Person will have already been, or will substantially concurrently be, provided to VAALCO;

(ii)

the Person submitting the TransGlobe Acquisition Proposal was not restricted from making such TransGlobe Acquisition Proposal pursuant to an existing confidentiality, standstill, non-disclosure, use, business purpose or similar agreement, restriction or covenant with TransGlobe or any of its Subsidiaries; and

(iii)

TransGlobe has been, and continues to be, in material compliance with this Section 5.8.

(f)	Notwithstanding any other provision of this Agreement, TransGlobe shall not make a TransGlobe Change in Recommendation in connection with a TransGlobe Acquisition Proposal unless all of the following conditions are satisfied:

(i)	the TransGlobe Board has determined that the TransGlobe Acquisition Proposal constitutes a TransGlobe Superior Proposal;

(iii)

TransGlobe has been, and continues to be, in material compliance with this Section 5.8;

(iv)

TransGlobe has promptly provided VAALCO with a notice in writing that there is a TransGlobe Superior Proposal, together with all documentation related to and detailing the TransGlobe Superior Proposal, including a copy of any proposed agreement and all ancillary documentation relating to such TransGlobe Superior Proposal as well as the cash value that the TransGlobe Board has, after consultation with outside financial advisors, determined should be ascribed to any non-cash consideration offered under the TransGlobe Superior Proposal;

(v)	five Business Days (the “VAALCO Response Period”) shall have elapsed from the date VAALCO received the notice and documentation referred to in Section 5.8(f)(iv) from TransGlobe; and

(vi)

if VAALCO has proposed to amend the terms of the Arrangement in accordance with Section 5.8(g), the TransGlobe Board shall have determined, in good faith, after consultation with its outside financial and legal advisors, that the TransGlobe Acquisition Proposal remains a TransGlobe Superior Proposal compared to the proposed amendment to the terms of the Arrangement by VAALCO, if applicable.

(g)	For greater certainty, notwithstanding any TransGlobe Change in Recommendation, unless this Agreement has been terminated in accordance with its terms, TransGlobe shall cause the TransGlobe

Meeting to occur and the Arrangement Resolution to be put to the TransGlobe Shareholders thereat for consideration in accordance with this Agreement, and TransGlobe shall not, except as required by applicable Law, submit to a vote of its shareholders any TransGlobe Acquisition Proposal other than the Arrangement Resolution prior to the termination of this Agreement.

(h)

TransGlobe acknowledges and agrees that, during the VAALCO Response Period or such longer period as TransGlobe may approve for such purpose, VAALCO shall have the opportunity, but not the obligation, to propose to amend the terms of this Agreement, including an increase in, or modification of, the Consideration. The TransGlobe Board will review any such proposal to determine in good faith whether VAALCO’s proposal to amend the Agreement would result in the TransGlobe Acquisition Proposal ceasing to be a TransGlobe Superior Proposal. If the TransGlobe Board determines that the TransGlobe Acquisition Proposal is not a TransGlobe Superior Proposal as compared to the proposed amendments to the terms of the Agreement, it will promptly advise VAALCO and enter into an amended agreement with VAALCO reflecting such proposed amendments. If the TransGlobe Board continues to believe in good faith, after consultation with its financial advisors and outside legal counsel, that such TransGlobe Acquisition Proposal remains a TransGlobe Superior Proposal and therefore rejects VAALCO’s offer to amend this Agreement and the Arrangement, if any, TransGlobe may, subject to compliance with the other provisions hereof, make a TransGlobe Change in Recommendation. Each successive modification of any TransGlobe Acquisition Proposal shall constitute a new TransGlobe Acquisition Proposal for the purposes of this Section 5.8 and VAALCO shall be afforded a new VAALCO Response Period in respect of each such TransGlobe Acquisition Proposal from the date on which VAALCO received the notice and documentation referred to in Section 5.8(f)(iv) in respect of such new TransGlobe Superior Proposal from TransGlobe.

(i)

The TransGlobe Board will promptly reaffirm the TransGlobe Board Recommendation by press release after: (A) the TransGlobe Board determines any TransGlobe Acquisition Proposal that has been publicly announced or publicly disclosed is not a TransGlobe Superior Proposal; or (B) the TransGlobe Board determines that a proposed amendment to the terms of the Arrangement would result in any TransGlobe Acquisition Proposal which has been publicly announced or made not being a TransGlobe Superior Proposal. VAALCO and its legal counsel will be given a reasonable opportunity to review and comment on the form and content of any such press release and TransGlobe will make all reasonable amendments to such press release as requested by VAALCO and its legal counsel.

(j)	Notwithstanding the foregoing, TransGlobe may effect a TransGlobe Change in Recommendation in response to a TransGlobe Intervening Event if and only if all of the following are satisfied:

(i)	the TransGlobe Board shall have determined in good faith (after consultation with its outside legal counsel) that the failure to effect a TransGlobe Change in Recommendation in response to such TransGlobe Intervening Event would be inconsistent with its fiduciary duties under applicable Law;

(ii)	the TransGlobe Shareholder Approval shall not have been obtained;

(iii)

TransGlobe shall have promptly provided VAALCO with a notice in writing that it intends to effect a TransGlobe Change in Recommendation in response to a TransGlobe Intervening Event, describing in reasonable detail the underlying facts giving rise to, and the reasons for making, such TransGlobe Change in Recommendation (it being understood that such notice shall not constitute a TransGlobe Change in Recommendation for purposes of this Agreement);

(iv)	five Business Days (the “VAALCO Intervening Event Response Period”) shall have elapsed from the date VAALCO received the notice referred to in Section 5.8(j)(iii) from TransGlobe; and

(v)	if VAALCO has proposed to amend the terms of the Arrangement in accordance with Section 5.8(k), the TransGlobe Board shall have determined after complying with its

obligations under Section 5.8(k), in good faith, after consultation with its outside legal advisors, that the failure to effect a TransGlobe Change in Recommendation in response to such TransGlobe Intervening Event would be inconsistent with its fiduciary duties under applicable Law.

(k)

TransGlobe acknowledges and agrees that, during the VAALCO Intervening Event Response Period or such longer period as TransGlobe may approve for such purpose, VAALCO shall have the opportunity, but not the obligation, to propose to amend the terms of this Agreement, including an increase in, or modification of, the Consideration. The TransGlobe Board will review any such proposal to determine in good faith whether VAALCO’s proposal to amend this Agreement would obviate the need to effect a TransGlobe Change in Recommendation in response to the TransGlobe Intervening Event. If the TransGlobe Board determines that it need not effect a TransGlobe Change in Recommendation in response to the TransGlobe Intervening Event in light of the proposed amendments to the terms of the Agreement, it will promptly advise VAALCO and enter into an amended agreement with VAALCO and AcquireCo reflecting such proposed amendments. If the TransGlobe Board continues to believe in good faith, after consultation with its outside legal counsel, that the failure to effect a TransGlobe Change in Recommendation in response to such TransGlobe Intervening Event would be inconsistent with its fiduciary duties under applicable Law and therefore rejects VAALCO’s offer to amend this Agreement and the Arrangement, if any, TransGlobe may, subject to compliance with the other provisions hereof, make a TransGlobe Change in Recommendation.

(l)

In circumstances where TransGlobe provides VAALCO with notice of a TransGlobe Superior Proposal and all documentation contemplated by Section 5.8(f)(iv) or a notice contemplated by Section 5.8(j)(iii), in each case, on a date that is less than seven Business Days prior to the TransGlobe Meeting, TransGlobe may, or if and as requested by VAALCO, TransGlobe shall, either proceed with or postpone the TransGlobe Meeting to a date that is not more than seven Business Days after the scheduled date of such TransGlobe Meeting, as directed by VAALCO, provided, however, that the TransGlobe Meeting shall not be adjourned or postponed to a date later than the fifth Business Day prior to the Outside Date.

(m)

Without limiting the generality of the foregoing, TransGlobe shall advise its Subsidiaries and its Representatives of the prohibitions set out in this Section 5.8 and any violation of the restrictions set forth in this Section 5.8 by TransGlobe, its Subsidiaries or Representatives is deemed to be a breach of this Section 5.8 by TransGlobe.

(n)

Nothing contained in this Section 5.8 shall prohibit TransGlobe or the TransGlobe Board or a committee thereof from making any disclosure to the TransGlobe Shareholders that is required by Law or stock exchange rule or listing agreement provided, however, that (i) TransGlobe shall provide VAALCO and its external legal counsel with a reasonable opportunity to review and comment on the form and content of any disclosure to be made pursuant to this Section 5.8(n) and shall give reasonable consideration to such comments, and (ii) this Section 5.8(n) shall not be deemed to permit the TransGlobe Board to make a TransGlobe Change in Recommendation other than in accordance with Section 5.8(f) or Section 5.8(j).

5.9	Certain VAALCO Covenants Regarding Non-Solicitation

(v)	make any public announcement or take any other action inconsistent with the approval, recommendation or declaration of advisability of the VAALCO Board of the transactions contemplated hereby.

(b)	TransGlobe and its Subsidiaries will not be obligated to participate in any Pre-Acquisition Reorganization under Section 5.12(a) unless such Pre-Acquisition Reorganization in the opinion of TransGlobe, acting reasonably:

The events provided for in this Section 3.1 will be deemed to occur on the Effective Date, notwithstanding that certain procedures related thereto may not be completed until after the Effective Date.

3.2	No Fractional Shares

(a)

In no event shall any TransGlobe Shareholder be entitled to a fractional VAALCO Share. Where the aggregate number of VAALCO Shares to be issued to a TransGlobe Shareholder as consideration under the Arrangement would result in a fraction of a VAALCO Share being issuable, the number of VAALCO Shares to be received by such TransGlobe Shareholder shall be rounded down to the nearest whole VAALCO Share. In lieu of any such fractional VAALCO Share, each TransGlobe Shareholder otherwise entitled to a fractional interest in a VAALCO Share will be entitled to receive a cash payment equal to an amount representing such TransGlobe Shareholder’s proportionate interest in the net proceeds from the sale by the Depositary on behalf of all such TransGlobe Shareholders of the VAALCO Excess Shares.

(b)

As promptly as practicable following the Effective Time, the Depositary shall determine the excess of (i) the number of VAALCO Shares issued and delivered to the Depositary pursuant to Article 5 representing the Consideration Shares over (ii) the aggregate number of whole Consideration Shares to be issued to TransGlobe Shareholders pursuant to Section 3.1(f) (such excess the “VAALCO Excess Shares”). Following the Effective Time, the Depositary shall, on behalf of the former TransGlobe Shareholders, sell the VAALCO Excess Shares at the then prevailing prices on the NYSE. The sale of the VAALCO Excess Shares by the Depositary shall be executed on the NYSE through one or more member firms of the NYSE and shall be executed in round lots to the extent applicable. The Depositary shall use its commercially reasonable efforts to complete the sale of the VAALCO Excess Shares as promptly following the Effective Time as is practicable, consistent with obtaining the best execution of such sales in light of prevailing market conditions. Until the net proceeds of such sale or sales have been distributed to former TransGlobe Shareholders, the Depositary shall hold such proceeds in trust for such former TransGlobe Shareholders (the “VAALCO Share Trust”). The amount of all commissions, transfer taxes and other out-of-pocket transaction costs, including expenses and compensation of the Depositary incurred in connection with such sale of VAALCO Excess Shares shall be paid by VAALCO. The Depositary shall determine the portion of the VAALCO Share Trust to which each former TransGlobe Shareholder is entitled, if any, by multiplying the amount of the aggregate net proceeds composing the VAALCO Share Trust by a fraction, the numerator of which is the amount of the fractional share interest to which such former TransGlobe Shareholder is entitled (after taking into account all TransGlobe Shares held as of immediately prior to the Effective Time by such former TransGlobe Shareholder) and the denominator of which is the aggregate amount of fractional VAALCO Shares to which all former TransGlobe Shareholders are entitled.

A-69

TABLE OF CONTENTS

(c)	As soon as practicable after the determination of the amount of cash, if any, to be paid to former TransGlobe Shareholders with respect to any fractional VAALCO Shares, the Depositary shall make available such amounts to such former TransGlobe Shareholders.

ARTICLE 4

DISSENT RIGHTS

4.1	Dissent Rights

Dissenting Shareholders who are:

(i)

ultimately entitled to be paid by VAALCO the fair value for their Dissent Shares (A) shall be deemed to not to have participated in the transactions in Article 3 (other than Section 3.1(e)); (B) shall be deemed to have transferred and assigned such Dissent Shares (free and clear of any Liens) to AcquireCo in accordance with Section 3.1(e); (C) will be entitled to be paid the fair value of such Dissent Shares by AcquireCo, which fair value, notwithstanding anything to the contrary contained in the ABCA, shall be determined as of the close of business on the day before the Arrangement Resolution was adopted at the TransGlobe Meeting; and (D) will not be entitled to any other payment or consideration, including any payment that would be payable under the Arrangement had such holders not exercised their Dissent Rights in respect of such TransGlobe Shares; or

(ii)

ultimately not entitled, for any reason, to be paid by VAALCO the fair value for their Dissent Shares, shall be deemed to have participated in the Arrangement in respect of those TransGlobe Shares on the same basis as a non-dissenting TransGlobe Shareholder and shall be entitled to receive only the Consideration from VAALCO in the same manner as such non-Dissenting Shareholders.

(b)

In no event shall VAALCO or TransGlobe or any other Person be required to recognize a Dissenting Shareholder as a registered or beneficial owner of TransGlobe Shares or any interest therein (other than the rights set out in this Section 4.1) at or after the Effective Time, and as at the Effective Time the names of such Dissenting Shareholders shall be deleted from the central securities register of TransGlobe.

(c)

For greater certainty, in addition to any other restrictions in the Interim Order and under Section 191 of the ABCA, none of the following shall be entitled to exercise Dissent Rights: (i) TransGlobe Shareholders who vote or have instructed a proxyholder to vote such TransGlobe Shares in favour of the Arrangement Resolution (but only in respect of such TransGlobe Shares), (ii) the TransGlobe Equity Award Holders, and (iii) any other Person who is not a registered holder of TransGlobe Shares as of the record date for the TransGlobe Meeting. A Person may only exercise Dissent Rights in respect of all, and not less than all, of such Person’s TransGlobe Shares.

Upon surrender to the Depositary for cancellation of a certificate which immediately prior to the Effective Time represented outstanding TransGlobe Shares that were transferred pursuant to Section 3.1(f), together with a duly completed and executed Letter of Transmittal and any such additional documents and instruments as the Depositary may reasonably require, the registered holder of the TransGlobe Shares represented by such surrendered certificate shall be entitled to receive in exchange therefor, and the Depositary shall deliver to such TransGlobe Shareholder the Consideration that such TransGlobe Shareholder has the right to receive under the Arrangement for such TransGlobe Shares, less any amounts withheld pursuant to Section 5.3, and any certificate so surrendered shall forthwith be cancelled.

(d)

Following receipt of the Final Order and prior to the filing of the Articles of Arrangement, TransGlobe shall deliver or cause to be delivered to the Depositary (unless the parties otherwise agree) sufficient funds to satisfy the aggregate amount of cash payable to the holders of the TransGlobe Options, TransGlobe Surrendered DSUs, TransGlobe Surrendered PSUs and TransGlobe Surrendered RSUs, in accordance with Section 3.1, which cash shall be held by the Depositary as agent and nominee for such former holders of TransGlobe Options, TransGlobe Surrendered DSUs, TransGlobe Surrendered PSUs and TransGlobe Surrendered RSUs for distribution to such former holders of TransGlobe Options, TransGlobe Surrendered DSUs, TransGlobe Surrendered PSUs and TransGlobe Surrendered RSUs in accordance with the provisions of this Article 5. The delivery of such funds to the Depositary following receipt of the Final Order and prior to the Effective Time shall constitute full satisfaction of the rights of former holders of TransGlobe Options, TransGlobe Surrendered DSUs, TransGlobe Surrendered PSUs and TransGlobe Surrendered RSUs and such former holders of TransGlobe Options, TransGlobe Surrendered DSUs, TransGlobe Surrendered PSUs and TransGlobe Surrendered RSUs shall have no claim against TransGlobe, AcquireCo or VAALCO except to the extent that the funds delivered by TransGlobe to the Depositary (except to the extent such funds are withheld in accordance with Section 5.3) are insufficient to satisfy the amounts payable to such former holders of TransGlobe Options, TransGlobe Surrendered DSUs, TransGlobe Surrendered PSUs and TransGlobe Surrendered RSUs or are not paid by the Depositary to such former holders of TransGlobe Options, TransGlobe Surrendered DSUs, TransGlobe Surrendered PSUs and TransGlobe Surrendered RSUs in accordance with the terms hereof. As soon as practicable after the Effective Time, the Depositary shall pay or cause to be paid the amounts, less applicable withholdings, to be paid to former holders of TransGlobe Options, TransGlobe Surrendered DSUs, TransGlobe Surrendered PSUs and TransGlobe Surrendered RSUs pursuant to this Plan of Arrangement.

When authorizing such consideration in exchange for any lost, stolen or destroyed certificate, the Person to whom such Consideration is to be delivered shall as a condition precedent to the delivery of such Consideration, give a bond satisfactory to VAALCO, TransGlobe and the Depositary (acting reasonably) in such sum as VAALCO may direct, or otherwise indemnify VAALCO, AcquireCo and TransGlobe in a manner satisfactory to VAALCO and TransGlobe, each acting reasonably, against any claim that may be made against VAALCO, AcquireCo and TransGlobe with respect to the certificate alleged to have been lost, stolen or destroyed.

VAALCO, AcquireCo, TransGlobe, any of their affiliates and the Depositary, as applicable, shall be entitled to deduct and withhold, or direct any other Person to deduct and withhold on their behalf, from any amounts otherwise payable, issuable or otherwise deliverable to any TransGlobe Shareholder, any TransGlobe Equity Award Holder, and/or any other Person under this Plan of Arrangement such amounts as are required or reasonably believed to be required to be deducted and withheld from such amounts under any provision of the Tax Act, the United States Internal Revenue Code of 1986 or any provision of any other Law. To the extent any such amounts are so deducted and withheld, such amounts shall be treated for all purposes under this Plan of Arrangement as having been paid to the Person in respect of which such deduction and withholding was made. To the extent that the amount so required to be deducted or withheld from any amounts payable, issuable or otherwise deliverable to a Person under this Plan of Arrangement exceeds the amount of cash, if any, otherwise payable to such Person, VAALCO, TransGlobe, any of their affiliates and the Depositary are hereby authorized to sell or otherwise dispose, or direct any other Person to sell or otherwise dispose, of such portion of the non-cash consideration or non-cash amounts payable, issuable or otherwise deliverable hereunder to such Person as is necessary to provide sufficient funds to VAALCO, TransGlobe, any of their affiliates and the Depositary, as the case may be, to enable it to comply with such deduction or withholding requirement and none of VAALCO, TransGlobe, any of their affiliates or the Depositary shall be liable to any Person for any deficiency in respect of any proceeds received, and VAALCO, TransGlobe, any of their affiliates and the Depositary, as applicable, shall notify the relevant Person of such sale or other disposition and remit to such Person any unapplied balance of the net proceeds of such sale or other disposition (after deduction for (x) the amounts required to satisfy the required withholding under the Plan of Arrangement in respect of such Person, (y) reasonable commissions payable to the broker and (z) other reasonable costs and expenses).

5.4	Distributions with respect to Unsurrendered Share Certificates

No dividend or other distribution declared or made after the Effective Time with respect to VAALCO Shares with a record date after the Effective Time shall be delivered to the holder of any unsurrendered certificate that, immediately prior to the Effective Time, represented outstanding TransGlobe Shares unless and until the holder of such certificate shall have complied with the provisions of Section 5.1 or Section 5.2. Subject to applicable Law and to Section 5.3, at the time of such compliance, there shall, in addition to the delivery of Consideration to which such holder is thereby entitled, be delivered to such holder, without interest, the amount of the dividend or other distribution with a record date after the Effective Time theretofore paid with respect to such VAALCO Shares.

To the extent that a former TransGlobe Shareholder shall not have complied with the provisions of Section 5.1 or Section 5.2 on or before the date that is the last Business Day prior to the third anniversary of the Effective Date (the “final proscription date”), then the Consideration that such former TransGlobe Shareholder was entitled to receive shall be automatically cancelled without any repayment of capital in respect thereof and the Consideration to which such former TransGlobe Shareholder was entitled, shall be delivered to VAALCO by the Depositary and the VAALCO Shares forming part of the Consideration shall be deemed to be cancelled, and the interest of the former TransGlobe Shareholder in such VAALCO Shares (and any dividend or other distribution referred to in Section 5.4) to which it was entitled shall be terminated as of such final proscription date, and the certificates formerly representing TransGlobe Shares shall cease to represent a right or claim of any kind or nature as of such final proscription date. Any payment made by way of cheque by the Depositary pursuant to this Plan of Arrangement that has not been deposited or has been returned to the Depositary or that otherwise remains unclaimed, in each case, on or before the final proscription date shall cease to represent a right or claim of any kind or nature and the right of any TransGlobe Shareholder to receive the Consideration for TransGlobe Shares pursuant to this Plan of Arrangement shall terminate and be deemed to be surrendered and forfeited to VAALCO.

5.6

No Liens

Any exchange or transfer of securities pursuant to this Plan of Arrangement shall be free and clear of any Liens or other claims of third parties of any kind.

VAALCO Energy, Inc.

Houston, TX 77042

Members of the Board:

Stifel, Nicolaus & Company, Incorporated (“Stifel” or “we”) has been advised that VAALCO Energy, Inc., a corporation existing under the laws of the State of Delaware, U.S.A. (“VAALCO”), is considering entering into an Arrangement Agreement (the “Arrangement Agreement”) with TransGlobe Energy Corporation, a corporation existing under the laws of the Province of Alberta, Canada (“TransGlobe”), pursuant to which, among other things, (i) VAALCO will acquire all of the issued and outstanding common shares of TransGlobe (“TransGlobe Shares”) and (ii) each issued and outstanding TransGlobe Share (excluding any TransGlobe Shares held by VAALCO or any of its affiliates) will be deemed to be transferred and assigned by the holder thereof, without any further act or formality on its part, to VAALCO in exchange for 0.6727 shares of VAALCO’s common stock, $0.10 par value per share (the “Consideration”), subject to adjustment and on terms and conditions more fully set forth in the Arrangement Agreement (including the form of Plan of Arrangement, to be attached as Schedule A to the Arrangement Agreement (the “Plan of Arrangement”)) (the “Transaction”).

The Board of Directors of VAALCO (the “Board”) has requested Stifel’s opinion, as investment bankers, as to the fairness, from a financial point of view, to VAALCO of the Consideration to be paid by VAALCO to the holders of TransGlobe Shares in the Transaction pursuant to the Arrangement Agreement (the “Opinion”).

In rendering our Opinion, we have, among other things:

(i)	reviewed the financial terms contained in a draft copy of the Arrangement Agreement dated July 13, 2022 and a draft copy of the form of Plan of Arrangement dated July 13, 2022;

(ii)

(iii)

reviewed and analyzed certain internal financial analyses, financial projections, reports and other information concerning VAALCO and TransGlobe prepared by the management of VAALCO and TransGlobe, respectively, including projections for each of VAALCO and TransGlobe provided by the management of VAALCO and TransGlobe, respectively (the “VAALCO Projections” and the “TransGlobe Projections,” respectively), and utilized per instruction of VAALCO;

(iv)	discussed with certain members of VAALCO’s management the historical and current business operations, financial condition and prospects of VAALCO and TransGlobe and such other matters as Stifel deemed relevant;

(v)	reviewed and analyzed certain operating results of VAALCO and TransGlobe as compared to the operating results and the reported price and trading histories of certain publicly traded companies that Stifel deemed relevant;

(vi)	reviewed and analyzed certain financial terms of the Transaction as compared to the financial terms of certain selected business combinations that Stifel deemed relevant;

(viii)

held discussions with VAALCO’s senior management, including estimates of certain cost savings, operating synergies, transaction charges and the pro forma financial effects of the Transaction;

(ix)	reviewed and analyzed certain publicly available financial and stock market data relating to selected public companies that we deemed relevant to our analysis;

(x)	participated in certain discussions and negotiations between representatives of VAALCO and TransGlobe;

(xi)	reviewed the reported prices and trading activity of the equity securities of each of VAALCO and TransGlobe;

(xii)

reviewed and analyzed such other information and such other factors, and conducted such other financial studies, analyses and investigations and considered such other information as we deemed necessary or appropriate for purposes of our opinion; and

(xiii)

taken into account our assessment of general economic, market and financial conditions and our experience in other transactions, as well as our experience in securities valuations and our general knowledge of the industry in which VAALCO and TransGlobe operate.

In rendering our Opinion, we have relied upon and assumed, without independent verification, the accuracy and completeness of all of the financial and other information that was provided to Stifel by or on behalf of VAALCO or TransGlobe, or that was otherwise reviewed by Stifel, and have not assumed any responsibility for independently verifying any of such information. With respect to the financial forecasts supplied to us by VAALCO and TransGlobe (including, without limitation, the VAALCO Projections and the TransGlobe Projections), we have assumed, at the direction of VAALCO, that they were reasonably prepared on the basis reflecting the best currently available estimates and judgments of the management of VAALCO and TransGlobe, as applicable, as to the future operating and financial performance of VAALCO and TransGlobe, as applicable, and that they provided a reasonable basis upon which we could form our opinion. Without limiting the foregoing, we have assumed, at the direction of VAALCO and without independent verification, that the projections with respect to management payouts upon a change of control, inflation, well abandonment expenditures, cost savings and payment obligations under the fiscal regime of each applicable jurisdiction included in the financial forecasts supplied to us by VAALCO and TransGlobe (including, without limitation, the VAALCO Projections and the TransGlobe Projections) were reasonably prepared and are consistent with the laws of the applicable jurisdictions and the terms of any applicable contracts or other governing documents or agreements. Such forecasts and projections were not prepared with the expectation of public disclosure. All such forecasted or projected financial information is based on numerous variables and assumptions that are inherently uncertain, including, without limitation, factors related to general economic and competitive conditions. Accordingly, actual results could vary significantly from those set forth in such forecasted or projected financial information. Stifel has relied on this projected information without independent verification or analyses and does not in any respect assume any responsibility for the accuracy or completeness thereof. Stifel expresses no opinion as to the VAALCO Projections, the TransGlobe Projections or any other estimates, forecasts or projections or the assumptions on which they were made.

We also assumed that there were no material changes in the assets, liabilities, financial condition, results of operations, business or prospects of either VAALCO or TransGlobe since the respective dates of the last financial statements of each company made available to us. We have relied upon the assessments of the managements of VAALCO and TransGlobe, as the case may be, as to the oil, natural gas and/or natural gas liquids reserves, and acquisition, disposition, drilling, completion, production and development activities and exploration projects of VAALCO and TransGlobe, and related expenditures and capital funding requirements for VAALCO’s and TransGlobe’s operations. We have not made or, except for certain reserve reports relating to VAALCO and TransGlobe ((i) in the case of VAALCO, (A) the report on VAALCO’s reserves data as at December 31, 2021 by Netherland, Sewell & Associates, Inc., dated February 4, 2022 and (B) the Competent Person’s Report on VAALCO’s reserves data as at December 31, 2021 by Netherland, Sewell & Associates, Inc., dated March 12, 2022, and (ii) in the case of TransGlobe, the report on TransGlobe’s reserves data as at December 31, 2021 by GLJ Ltd., dated February 22, 2022), been provided with any independent evaluation or appraisal of the assets or liabilities(contingent, accrued, derivative, off-balance sheet or otherwise) of VAALCO, TransGlobe or any other entity nor have we made

any physical inspection of the properties or assets of VAALCO, TransGlobe or any other entity. We do not conduct or provide geological, environmental or other technical assessments and are not experts in the evaluation of oil, natural gas liquids or natural gas reserves or properties and we express no view or opinion as to reserve quantities, or the exploration, development or production (including, without limitation, as to the feasibility or timing thereof and associated expenditures), of any properties of VAALCO, TransGlobe or any other entity. Without limiting the foregoing, we have assumed, based on the information provided by the management of TransGlobe and without independent verification, that, as of the date of this Opinion, TransGlobe will receive full payment from Egyptian General Petroleum Corporation on all outstanding accounts receivable resulting from the merger of its three Eastern Desert production-sharing concessions in Egypt. Estimates of values of companies and assets do not purport to be appraisals or necessarily reflect the prices at which companies or assets may actually be sold. Because such estimates are inherently subject to uncertainty, Stifel assumes no responsibility for their accuracy.

We have assumed, with your consent, that there are no factors that would delay or subject to any adverse conditions any necessary regulatory or governmental approvals, consents, releases or waivers and that all conditions to the Transaction (including any required regulatory approvals) will be satisfied and not waived. In addition, we have assumed that the definitive Arrangement Agreement and the definitive Plan of Arrangement will not differ materially from the drafts we reviewed. We have also assumed that the Transaction will be consummated substantially on the terms and conditions described in the Arrangement Agreement and the Plan of Arrangement, without any waiver or modification of any material term or condition by VAALCO or any other party and without any anti-dilution or other adjustment to the Consideration, and that obtaining any necessary regulatory or other approvals, consents, releases and waivers or satisfying any other conditions for consummation of the Transaction will not have an adverse effect on VAALCO, TransGlobe or the Transaction. Without limiting the foregoing, we have assumed, at the direction of VAALCO, that no payment (including any assignment, change-of-control, consent fee, bonus or other payment) will be required to be made by either VAALCO or TransGlobe or any of their affiliates in connection with the Transaction to any governmental body, agency, authority or entity or to any employee, officer or representative of, or any person otherwise acting in an official capacity for or on behalf of any governmental body, agency, authority or entity. We have assumed, in all respects material to our Opinion, that the representations and warranties of VAALCO and TransGlobe in the Arrangement Agreement are true and correct and that all such parties will comply with each of their covenants in the Arrangement Agreement and the Plan of Arrangement. We have assumed that the Transaction will be consummated in a manner that complies with the applicable provisions of the Securities Act of 1933, as amended, the Securities Exchange Act of 1934, as amended, and all other applicable federal and state statutes, rules and regulations and all applicable statutes, rules and regulations of other jurisdictions (including, without limitation, the United Kingdom, Canada, Egypt, Gabon and Equatorial Guinea). We have further assumed that

VAALCO has relied upon the advice of its counsel, independent accountants and other advisors (other than Stifel) as to all legal, financial reporting, tax, accounting and regulatory matters with respect to VAALCO, the Transaction and the Arrangement Agreement.

Our Opinion is limited to whether the Consideration to be paid by VAALCO to the holders of TransGlobe Shares is fair to VAALCO, from a financial point of view, and does not address any other terms, aspects or implications of the Transaction, including, without limitation, the form or structure of the Transaction or any other part of the Transaction, any individual transaction or group of transactions, or the terms, conditions or any other aspect of any individual transaction or group of transactions, that is or are part of the Transaction, any consequences of the Transaction on VAALCO, its stockholders, creditors or otherwise, or any terms, aspects or implications of any voting, support, stockholder or other agreements, arrangements or understandings contemplated or entered into in connection with the Transaction or otherwise. Our Opinion also does not consider, address or include: (i) any other strategic alternatives currently (or which have been or may be) contemplated by the Board or VAALCO; (ii) the legal, financial reporting, tax, accounting or regulatory consequences of the Transaction on VAALCO or the holders of VAALCO’s Common Stock; (iii) the fairness (financial or otherwise) of the amount, nature or any other aspect of any compensation to any of the officers, directors or employees of any party to the Transaction or any related entities, or class of such persons, relative to the compensation to the holders of such entity’s securities or otherwise; or (iv) the effect of the Transaction on, or the fairness of the consideration to be received by, holders of any class of VAALCO’s

securities, or any class of securities of any other party to any transaction contemplated by the Arrangement Agreement or the Plan of Arrangement. Furthermore, we are not expressing any opinion herein as to the prices, trading range or volume at which VAALCO’s or TransGlobe’s securities will trade following public announcement or consummation of the Transaction.

Our Opinion is necessarily based on economic, market, financial and other conditions as they exist on, and on the information made available to us by or on behalf of VAALCO or its advisors, or information otherwise reviewed by Stifel, as of the date of this Opinion. It is understood that subsequent developments may affect the conclusion reached in this Opinion and that Stifel does not have any obligation to update, revise or reaffirm this Opinion. Further, as the Board is aware, the credit, financial, stock and commodity markets have been experiencing unusual volatility and we express no opinion or view as to any potential effects of such volatility on VAALCO, TransGlobe or the Transaction. Our Opinion is solely for the information of, and directed to, the Board for its information and assistance in connection with its consideration of the financial terms of the Transaction and should not be relied upon by any other person. Our Opinion does not constitute a recommendation to the Board or any other person as to how the Board or any other person should vote or otherwise act on the Transaction or any other matter or to any shareholder of VAALCO or TransGlobe as to how any such shareholder should vote or act with respect to the Transaction or any other matter, or whether or not any shareholder of VAALCO or TransGlobe should enter into a voting, shareholders’, or affiliates’ agreement with respect to the Transaction, or exercise any dissenters’ or appraisal rights that may be available to such shareholder. In addition, the Opinion does not compare the relative merits of the Transaction with any other alternative transactions or business strategies which may have been available to VAALCO and does not address the underlying business decision of the Board or VAALCO to proceed with or effect the Transaction.

We are not legal, tax, regulatory or bankruptcy advisors. We have not considered any potential legislative or regulatory changes currently being considered or recently enacted by the United States Congress, the various federal banking agencies, the SEC, or any other regulatory bodies of the United States or any other jurisdictions, or any changes in accounting methods or generally accepted accounting principles that may be adopted by the SEC or the Financial Accounting Standards Board, or any changes in regulatory accounting principles that may be adopted by any or all of the federal banking agencies or the banking agencies of any other jurisdictions. Our Opinion is not a solvency opinion and does not in any way address the solvency or financial condition of VAALCO or TransGlobe.

Stifel, as part of its investment banking services, is regularly engaged in the independent valuation of businesses and securities in connection with mergers, acquisitions, underwritings, sales and distributions of listed and unlisted securities, private placements and valuations for estate, corporate and other purposes. We have acted as financial advisor to VAALCO in connection with the Transaction and will receive a fee for our services, a substantial portion of which is contingent upon the completion of the Transaction (the “Advisory Fee”). We have acted as financial advisor to the Board and will receive a fee upon the delivery of this Opinion that is not contingent upon consummation of the Transaction (the “Opinion Fee”). We will not receive any other significant payment or compensation contingent upon the successful consummation of the Transaction. In addition, VAALCO has agreed to indemnify us for certain liabilities arising out of our engagement. Stifel served as financial advisor to VAALCO in connection with its potential acquisition of certain assets in West Africa, for which Stifel received compensation. There are no other material relationships that existed during the two years prior to the date of this Opinion or that are mutually understood to be contemplated in which any compensation was received or is intended to be received as a result of the relationship between Stifel and any party to the Transaction. Stifel may seek to provide investment banking services to VAALCO or its affiliates in the future, for which we would seek customary compensation. In the ordinary course of business, Stifel and our clients may transact in the equity securities of each of VAALCO and TransGlobe and may at any time hold a long or short position in such securities.

Stifel’s Fairness Opinion Committee has approved the issuance of this Opinion. Our Opinion may not be published or otherwise used or referred to, nor shall any public reference to Stifel be made, without our prior written consent, except in accordance with the terms and conditions of Stifel’s engagement letter agreement with VAALCO.
