A Message from our Board of Directors

April 25, 2023

DEAR FELLOW STOCKHOLDERS,

We are pleased to invite you to the Montauk Renewables, Inc. Annual Meeting of Stockholders at 9:00 (Eastern Daylight Time) on June 5, 2023. This year’s annual meeting will once again be held virtually, via live webcast.

2022 marked our first full year as a public company with Montauk Renewables traded on the Nasdaq Capital Market. Building on the success of 2021, we had revenue of $205.6 million in 2022, a 38.8% increase over the prior year. We continued the expansion of our Pico project with increased feedstock during the third quarter of 2022 and, with respect to the 2021 Montauk Ag Renewables acquisition, continue to work through the optimization of improvements to the patented reactor technology. In the fourth quarter, we began to relocate the reactor in Magnolia, NC to the Turkey, NC location to centralize processing at one location. We announced construction of a second RNG processing facility at the Apex landfill and commenced capital improvements at the Raeger facility to significantly increase production. Finally, we are pleased to announce that we were awarded our 13^th landfill RNG facility marking our entrance into South Carolina.

With over 30 years of industry experience and a committed employee base, we are well positioned to succeed in the dynamic environment and are excited to enter what we consider to be the next phase of strategic growth of Montauk in 2023. On behalf of the Board of Directors, thank you for your continued investment in Montauk Renewables and our unwavering mission to bring commercial-scale renewable energy to market.

Sincerely,

LOGO

John A. Copelyn

Chairman of the Board

If you have received a Notice, and you would prefer to receive proxy materials (including a proxy card) in printed form by mail or electronically by email, please follow the instructions contained in the Notice.

GENERAL INFORMATION

We are furnishing you this proxy statement in connection with the solicitation of proxies by the Board of Directors (the “Board”) of Montauk Renewables, Inc., a Delaware corporation (the “Company,” “Montauk,” “we,” “us,” or “our”). This proxy statement addresses the items of business for the Annual Meeting to be held on Monday, June 5, 2023, or any postponement or adjournment thereof, and is being first released to stockholders on April 25, 2023. We will hold the Annual Meeting at 9:00 a.m., Eastern Daylight Time, virtually via live webcast at www.virtualshareholdermeeting.com/MNTK2023.

Our common stock, par value $0.01 per share (“common stock”), is listed on The Nasdaq Capital Market (“Nasdaq”) and trades under the ticker symbol “MNTK,” with a secondary listing on the Johannesburg Stock Exchange (“JSE”) and trading under the ticker symbol “MKR.” All of the shares of our common stock vote together as a single class for purposes of the proposals to be presented at the Annual Meeting. However, meeting attendance and voting instructions are different for shares traded on the Nasdaq and on the JSE and we encourage you to carefully read the instructions contained herein and in the other proxy materials.

EXPLANATORY NOTE

Montauk is an emerging growth company (“EGC”) under applicable U.S. securities laws and therefore is permitted to take advantage of reduced public company reporting requirements. As an EGC, we provide in this proxy statement the scaled disclosure permitted under the U.S. Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”). Accordingly, our compensation disclosures in this proxy statement generally align to a “smaller reporting company,” as that term is defined in Rule 12b-2 of the U.S. Securities Exchange Act of 1934, as amended (the “Exchange Act”), with certain exceptions (such as those that are afforded to EGCs but not smaller reporting companies). In addition, as an EGC, we are not required to conduct votes seeking approval, on an advisory basis, of the compensation of our named executive officers or the frequency with which such votes must be conducted.

PROXY SUMMARY

This Summary highlights information contained elsewhere in this proxy statement. This summary does not contain all of the information that you should consider. Please read the entire proxy statement carefully before voting.

General Information About the 2023 Annual Meeting of Stockholders

• Time and Date: Monday, June 5, 2023, at 9:00 a.m. Eastern Daylight Time

• Virtual Meeting: Online at www.virtualshareholdermeeting.com/MNTK2023

• Record Date: Friday, April 14, 2023

• Voting: For all matters, stockholders as of the Record Date have one vote for each share of capital stock held by such person on the Record Date.

Virtual Annual Meeting

As permitted by Delaware law and our Amended and Restated Bylaws (the “Bylaws”), we will hold a virtual annual meeting to maximize the ability of our stockholders to attend and participate in the Annual Meeting. We believe that the use of this virtual meeting format is the right choice for a company like Montauk, as it not only brings cost savings to us and our stockholders, but also increases our ability to engage with all stockholders, regardless of their size, resources, or physical location.

2 – Montauk Renewables, Inc.| 2023 Proxy Statement

PROPOSAL NO. 1

ELECTION OF DIRECTORS

Our business and affairs are managed under the direction of our Board. Our Amended and Restated Certificate of Incorporation generally provides that our Board consists of such number of directors as the Board may from time to time exclusively determine. Our Board of Directors is currently comprised of six members.

Our Amended and Restated Certificate of Incorporation provides that our Board is divided into three classes with staggered three-year terms. While our Board of Directors is classified, only one class of directors will be elected at each annual meeting of stockholders, with the other classes continuing for the remainder of their respective three-year terms. Our Board of Directors is designated as follows:

•

Messrs. Ahmed and Copelyn serve as Class I directors, and their terms will expire at the annual meeting of stockholders to be held in 2024;

•

Messrs. Govender and Shaik serve as Class II directors, and their terms will expire at the annual meeting of stockholders to be held in 2025; and

•

Mr. McClain and Ms. Cunningham serve as Class III directors and are nominated for re-election to serve until their terms expire at the annual meeting of stockholders to be held in 2026.

Any additional directorships resulting from an increase in the number of directors will be distributed among the three classes so that, as nearly as possible, each class will consist of one-third of our directors. Each director whose term expires at the 2028 annual meeting of stockholders or any annual meeting thereafter will be elected for a term expiring at the next annual meeting of stockholders. As a result of these provisions, beginning with the 2030 annual meeting of stockholders, all of our directors will be subject to annual election.

Directors are elected by a plurality of the votes cast by the holders of shares of common stock present in person or represented by proxy and entitled to vote on the election of directors. Accordingly, the two nominees receiving the highest number of affirmative votes will be elected. Shares represented by executed proxies will be voted, if authority to do so is not withheld, for the election of each of the nominees named below. Any incumbent nominee for director in an uncontested election (i.e., an election where the only nominees are those recommended by the Board) who receives a greater number of votes against his or her election than votes for such election (a “Majority Against Vote”) will promptly tender his or her resignation following certification of the stockholder vote. The Nominating and Corporate Governance Committee will promptly consider the tendered resignation and will recommend to the Board whether to accept the tendered resignation or to take some other action, such as rejecting the tendered resignation and addressing the apparent underlying causes of the Majority Against Vote.

If the nominee becomes unavailable for election because of an unexpected occurrence, shares that would have been voted for that nominee will instead be voted for the election of a substitute nominee proposed by the Company or the size of the Board will be reduced by one director. Each person nominated for election has consented to being named as a nominee in this proxy statement and has agreed to serve if elected. We have no reason to believe that any nominee will be unable to serve. The following is a brief biography of the nominees for election at the Annual Meeting. Each biography includes information regarding the specific experience, qualifications, attributes, or skills that led the Nominating and Corporate Governance Committee and the Board to determine that the applicable nominee or other current director should serve as a member of the Board.

Montauk Renewables, Inc.| 2023 Proxy Statement – 3

Corporate Governance Highlights

Our Board has a strong commitment to ethical conduct and good corporate governance, which promotes the long-term interests of stockholders, strengthens Board and management accountability and helps build public trust in the Company. Below is a summary of the Company’s current corporate governance policies.

•

Separation of CEO and Chairman – The roles of the Chief Executive Officer and the Chairman of the Board are separate.

•

Independent Lead Director who is separate from both the Chairman and the CEO.

•

Governance Guidelines – The Board has adopted Corporate Governance Guidelines (the “Guidelines”) which provide a framework for the effective governance of the Company. The Guidelines address matters such as the Board’s role, a director’s responsibilities, director qualification standards, and Board leadership and committee structure, among other matters. The Board regularly reviews developments in corporate governance and updates the Guidelines and other governance materials as it deems necessary and appropriate. The Guidelines are available on the Company’s website at https://ir.montaukrenewables.com/.

•

Board and Committee Meeting Attendance – In Fiscal 2022, each director attended at least 75% of the meetings of the Board and the committees on which the director served but for Mr. Raynor who resigned from the Board on February 28, 2022.

•

No Poison Pill – The Company currently does not have a poison pill in place.

•

Stock Ownership Guidelines for Directors and Executive Officers – The Company adopted Stock Ownership Guidelines for our directors and executives to effectively link the interests of management and our stockholders, while also promoting an ownership culture across the organization. We believe that Company stock should be acquired and held in quantities that encourage management to make decisions and take actions that will enhance Company performance and increase its value.

•

Policy Prohibiting Hedging, Pledging and Short Sales of Company Securities – Our Insider Trading Policy (“Policy”) prohibits the hedging, pledging and short sales of Company securities by members of the Board of Directors, all executive officers and employees of the Company, as well as their family members and designees, as further detailed in the Policy.

Montauk Renewables, Inc.| 2023 Proxy Statement – 7

•

Clawback policy for restatement of financial statements due to misconduct.

•

Code of Business Conduct and Ethics and associated training programs.

Code of Business Conduct and Ethics

All our directors, officers and employees must adhere to our Code of Business Conduct and Ethics (the “Code”). The Code is available on our website at https://ir.montaukrenewables.com.

The Code is designed to deter wrongdoing and promote:

•

honest and ethical conduct, including the ethical handling of actual or apparent conflicts of interest between personal and professional relationships;

•

full, fair, accurate, timely and understandable disclosure in reports and documents that Montauk files with, or submits to, the SEC or any other governmental agency and in other public communications;

•

compliance with applicable governmental laws, rules and regulations;

•

the prompt internal reporting of violations of the Code to the persons identified therein; and

•

accountability for adherence to the Code.

We view violations of the Code very seriously and aggressively investigate all alleged misconduct. Personal consequences for violations can be severe and can include termination of employment. All persons are strongly encouraged to promptly report any Code-related concerns to the Company. Individuals can report a concern or potential violation of the Code:

•

By speaking with the employee’s immediate supervisor, another supervisor or member of management, or by contacting Human Resources;

•

In a writing directed to Montauk Renewables Inc., Attention: Chief Legal Officer and Secretary, 5313 Campbells Run Road, Suite 200, Pittsburgh, PA 15205; or

•

By calling the Company’s toll-free, third-party managed, hotline at 1-833-222-3934. The hotline is available twenty-four (24) hours a day and may be used on a confidential and anonymous basis (where allowed by law).

Director Independence and Controlled Company Exemption

Certain stockholders, which are Messrs. Copelyn’s and Govender’s respective affiliates, have entered into the Consortium Agreement, dated January 26, 2021, whereby the parties agreed to act in concert with respect to voting our common stock in the election of directors, among other matters. The Consortium Agreement is described in the “Certain Relationships and Related Person Transactions” section of this proxy statement.

The parties to the Consortium Agreement beneficially own approximately 52.1% of our common stock as of April 14, 2023. As a result, we are a “controlled company” within the meaning of the Nasdaq listing rules. We will remain a “controlled company” so long as more than 50% of the voting power for the election of directors is held by parties to the Consortium Agreement. As such, we intend to avail ourselves of the controlled company exemptions under the Nasdaq listing rules. As a controlled company, we are not required to have a majority of our Board comprised of “independent directors,” as defined under the Nasdaq listing rules, or to have a Compensation Committee or a Nominating and Corporate Governance Committee composed of independent directors. We may continue to rely on these exemptions so long as we remain a “controlled company.”

The “controlled company” exemption does not modify the independence requirements for the Audit Committee, and we comply with the requirements of Rule 10A-3 of the Exchange Act and the Nasdaq listing rules, which require that our Audit Committee be composed of at least three members, all of whom are independent.

The Board has undertaken a review of the independence of the directors and considered whether any director has a material relationship with us that could compromise his or her ability to exercise independent judgment in carrying out his or her responsibilities. As a result of this review, the Board has affirmatively determined that Messrs. Ahmed and Shaik, and Ms. Cunningham are “independent directors” as defined under the Nasdaq listing requirements and Rule 10A-3 of the Exchange Act. In making these independence determinations, our Board reviewed and discussed information provided by the directors to us about each director’s business and personal activities and relationships as they may relate to us and our

8 – Montauk Renewables, Inc.| 2023 Proxy Statement

management. In addition to determining whether each director satisfies the director independence requirements set forth in the Nasdaq listing requirements, in the case of members of the Audit Committee (comprised of Messrs. Ahmed and Shaik and Ms. Cunningham), our Board also made an affirmative determination that all members of the Audit Committee satisfy independence requirements under SEC rules. The Board also affirmatively determined that Messrs. Jacobson and Raynor were independent under the Nasdaq listing standards and under Rule 10A-3 of the Exchange Act prior to their departures from the Board on March 30, 2023 and February 28, 2022, respectively.

Board Leadership Structure

Our Bylaws and Guidelines give the Board flexibility to determine whether the roles of Chief Executive Officer and Chairman of the Board should be held by the same person or by two separate individuals. When the roles of Chairman of the Board and Chief Executive Officer are combined in one individual or if the Chairman of the Board is a non-independent director, the Board may also designate an independent Lead Director to provide additional leadership and guidance to the Board.

The Board believes that our stockholders are best served at this time by having both a Lead Director and a Chairman of the Board, both of which are integral parts of our Board structure and effective corporate governance. Currently, Mr. Ahmed serves as our independent Lead Director, and Mr. Copelyn serves as our Chairman of the Board. Both bring considerable skills and experience, as described above, to their Board leadership roles.

The independent Lead Director will:

•

preside at all meetings of the Board at which the Chairman of the Board is not present, including executive sessions of the independent directors;

•

serve as liaison between the Chairman of the Board and the independent directors;

•

approve information to be sent to the Board;

•

approve meeting agendas for the Board;

•

approve meeting schedules to assure that there is sufficient time for discussion of all agenda items;

•

have the authority to call meetings of independent directors; and

•

if requested by major stockholders, be available for consultation and direct communication.

The active involvement of our independent directors, combined with the qualifications and significant responsibilities of our Chairman, independent Lead Director and other directors, provide balance on the Board and promote strong, independent oversight of our management and affairs, including risk.

The positions of Chairman of the Board and Chief Executive Officer are currently held by different individuals. The Board believes that the current separation of the roles of Chief Executive Officer, Chairman of the Board and independent Lead Director enhances the ability of the Board to carry out its roles and responsibilities on behalf of the stockholders and benefits the Company’s overall corporate governance. Our Chief Executive Officer is responsible for determining the strategic direction and the day-to-day leadership of our Company. Our Chairman facilitates and provides leadership to our Board and executive management and ensures they are focused on key issues. The Chairman of the Board shares a common understanding of the organization with the executive management and provides focus to ensure our Board is effective in setting and implementing the Company’s strategy in coordination with our independent Lead Director.

Role of the Board in Risk Oversight

The Board and each of its committees has an active role in overseeing management of the Company’s risks. The Board regularly reviews information regarding our credit, liquidity and operations, among other matters. The Audit Committee’s charter mandates the Audit Committee to review and discuss with management, and our independent registered public accounting firm, as appropriate, our major financial risk exposures and the steps taken by management to monitor and control these exposures, including review of the state of the Company’s cybersecurity, emerging cybersecurity developments and threats, and the Company’s strategy to mitigate cybersecurity risks. The Compensation Committee is responsible for overseeing risks related to the Company’s overall compensation policies and programs and assessing whether such policies and programs encourage excessive or inappropriate risk taking. The Nominating Committee manages risks associated with the independence of the Board and potential conflicts of interest. The Environmental, Safety and Corporate Responsibility Committee provides oversight of risks associated with environmental and safety related matters. While each committee is

Montauk Renewables, Inc.| 2023 Proxy Statement – 9

responsible for evaluating certain risks and overseeing the management of such risks, the entire Board is regularly informed through committee reports about such risks.

Meeting Information

The Board of Directors held nine meetings during Fiscal 2022. Each director attended at least 75% of the total number of meetings of the Board and the committees on which they served with the exception Mr. Raynor who resigned from the Board of Directors on February 28, 2022. We expect all directors to attend our Annual Meeting absent exceptional circumstances.

All directors then serving on the Board attended the Annual Meeting in June 2022.

The Chairman of the Board presides over each Board meeting. The Board meets as frequently as it may determine necessary or appropriate considering current circumstances and in accordance with the schedule determined by the Chairman of the Board. An executive session of the non-management directors is held in conjunction with each regular meeting of the Board that is presided over by the Chairman. The Board also holds at least two executive sessions comprised only of independent directors annually at which our independent Lead Director presides.

The Company has established four standing committees of the Board, each of which operates under a written charter: an Audit Committee, a Compensation Committee, a Nominating and Corporate Governance Committee and an Environmental, Safety and Corporate Responsibility Committee (the “ESCR Committee”). The composition and responsibilities of each committee are described below. Members will continue to serve on these committees until their resignation or until otherwise determined by our Board.

Committee Functions

Below is a description of the Board’s four standing committees. The written charters of the committees, our Guidelines and Code are available on the Investor Relations section of our website at https://ir.montaukrenewables.com. Each of the committees has the authority to engage legal counsel or other experts or consultants, as it deems appropriate to carry out its responsibilities.

Audit Committee: Our Audit Committee consists of Messrs. Ahmed (chair) and Shaik and Ms. Cunningham. The Audit Committee, established in accordance with Section 3(a)(58)(A) of the Exchange Act, assists the Board in overseeing the Company’s financial reporting process. You can find additional information about the functions of the Audit Committee under

10 – Montauk Renewables, Inc.| 2023 Proxy Statement

the “Audit Committee Report” section of this proxy statement. The Board has determined that all the members of the Audit Committee are financially literate and independent, within the meaning of the Nasdaq listing standards and Rule 10A-3 of the Exchange Act and each of Messrs. Ahmed and Shaik qualifies as an audit committee financial expert in accordance with SEC rules.

The Audit Committee (1) assists the Board in its oversight of (a) the integrity of the Company’s financial statements, (b) the Company’s compliance with legal and regulatory requirements, (c) the independent auditors’ qualifications, independence, and performance, and (d) the performance of the Company’s internal audit function; (2) prepares the committee’s report to be included in the Company’s annual proxy statement; (3) advises and consults with management and the Board regarding the financial affairs of the Company; and (4) appoints, compensates, retains, terminates, oversees and evaluates the work of the Company’s independent auditors. The committee has the sole authority to appoint, retain, terminate and replace the Company’s independent auditors, subject to stockholder ratification with respect to retention at the next regularly scheduled annual meeting of stockholders.

Management is responsible for the Company’s financial reporting process and system of internal controls and for the preparation and presentation of consolidated financial statements in accordance with accounting principles generally accepted in the United States (“GAAP”). The independent auditors are responsible for planning and carrying out an audit of the financial statements and internal control over financial reporting in accordance with standards established by the Public Company Accounting Oversight Board (“PCAOB”) and issuing a report on that audit. The committee’s responsibility is to provide oversight to these processes. The committee does not certify the financial statements or guarantee the auditor’s report. To fulfill the audit committee’s oversight role, the committee relies (without independent verification) on the information provided to it, the representations made by management and the independent auditors and the report of the independent auditors.

Compensation Committee: Our Compensation Committee consists of Messrs. Copelyn (chair) and Govender. Messrs. Copelyn and Govender are not independent within the meaning of the Nasdaq listing standards. We intend to comply with the independence requirements for the members of the Compensation Committee within the time periods specified under, and as required by, applicable rules.

Our Compensation Committee is responsible for, among other things, (1) establishing the Company’s policies, programs and procedures for compensating and providing benefits to its officers and non-employee directors; (2) administering the Company’s equity and cash incentive plans (including reviewing, recommending and approving stock option and other equity incentive grants to officers); and (3) preparing the committee’s report to be included in the Company’s annual proxy statement. The Compensation Committee has the power to investigate any matter brought to its attention within the scope of its duties and authority.

The Chief Executive Officer may not participate in, or be present during, any deliberations or determinations of the Compensation Committee regarding his compensation. For executives other than the Chief Executive Officer, the Compensation Committee solicits and considers evaluations and recommendations submitted to the Compensation Committee by the Chief Executive Officer. In the case of the Chief Executive Officer, the evaluation of his performance is conducted by the Compensation Committee. The Compensation Committee administers the Montauk Renewables, Inc. Equity and Incentive Compensation Plan (the “Plan”). The Compensation Committee has not, as of the date of this proxy statement, delegated authority to any of the Company’s officers to make awards under the Plan. Neither the Compensation Committee nor management has retained a compensation consultant as of the date of this proxy statement.

Environmental, Safety and Corporate Responsibility Committee: Our ESCR Committee consists of Messrs. Shaik (chair) and Govender, and Ms. Cunningham. The Committee provides oversight of the Company’s policies and management systems with respect to environmental, safety, sustainability and corporate social responsibility policies, objectives, practices and risk exposures. The Committee’s scope includes oversight of the development and implementation of the Company’s environmental, social, and governance strategy, initiatives and disclosures.

Nominating and Corporate Governance Committee: The Nominating and Corporate Governance Committee consists of Messrs. Copelyn (chair) and Ahmed. Mr. Ahmed has been determined to be independent by the Board within the meaning of the Nasdaq listing standards. Mr. Copelyn is not independent within the meaning of such listing standards. We intend to comply with the independence requirements for all members of the Committee within the time periods specified under, and as required by, applicable rules.

Our Nominating and Corporate Governance Committee is responsible for, among other things, (1) identifying individuals qualified to become members of the Board, consistent with criteria approved by the Board; (2) recommending candidates (a) for election as directors at annual meetings of stockholders and (b) to fill Board vacancies and newly-created director positions; (3) recommending whether incumbent directors should be nominated for re-election to the Board upon expiration of their terms; (4) developing, recommending and annually reviewing the Guidelines and overseeing corporate governance

Montauk Renewables, Inc.| 2023 Proxy Statement – 11

matters applicable to the Board and the Company’s employees; (5) overseeing an annual review and evaluation of the Board and its committees; and (6) assessing and making recommendations to the Board regarding appointments to committees of the Board. The Nominating and Corporate Governance Committee has the power to investigate any matter brought to its attention within the scope of its duties.

Director Nominations. The Nominating and Corporate Governance Committee evaluates director nominees for election to the Board in the context of the current composition of the Board, skill set and experience needs, our operating requirements and the long-term interests of our stockholders. The Nominating and Corporate Governance Committee is responsible for periodically assessing, developing and communicating with the Board concerning the appropriate criteria required of Board members and the composition of the Board as a whole. This assessment includes factors that the Nominating and Corporate Governance Committee believes are necessary for one or more directors to possess, including independence; skill; integrity; diversity with respect to race, ethnicity, gender and sexual orientation; age; background and experience with comparable businesses and industries; the candidate’s experience relative to that of the rest of the Board; the extent to which the candidate will be a valuable and complimentary addition to the Board and any committees thereof; and any other factors that the Nominating and Corporate Governance Committee deems relevant to the current needs of the Board. All director nominees must possess the minimum qualifications of integrity, collegiality and business acumen.

Under the Nominating and Corporate Governance Committee’s charter, which incorporates a form of the “Rooney Rule,” when identifying candidates for Board membership, the Nominating and Corporate Governance Committee will include, and will request that any search firm it engages include gender and racially/ethnically diverse candidates in the pool of candidates from which director nominees are selected. The Nominating and Corporate Governance Committee assesses the effectiveness of this policy as part of its regular consideration of Board composition and the director recruitment process.

Overboarding Limits. A director who also serves as an executive officer of a public company may not serve on more than two U.S. public company boards, including our Board. Other directors may not serve on more than four U.S. public company boards, including our Board. Exceptions to these limits will be approved on a case-by-case basis by the Board, upon a recommendation by the Nominating and Corporate Governance Committee.

No Term Limits. The Board does not believe that it should limit the number of terms for which an individual may serve as a director. While term limits facilitate Board refreshment, they can also result in the loss of experience and expertise that is critical to effective operation of the Board. Longer tenured directors can provide valuable insight into the Company and its operations. To ensure that the Board continues to evolve and benefit from fresh perspectives and ideas, the Nominating and Corporate Governance Committee evaluates the qualifications and contributions of each incumbent director before recommending the nomination of such director for an additional term.

Stockholder Director Nominees. The Nominating and Corporate Governance Committee will consider stockholder recommendations of director candidates for election to the Board. The Nominating and Corporate Governance Committee uses the same evaluation process for all director candidates, described above, including for director candidates identified by stockholders. Stockholders who wish to recommend individuals for consideration by the Nominating and Corporate Governance Committee to become nominees for election to the Board at an annual meeting of stockholders may do so by delivering a written recommendation to the Nominating and Corporate Governance Committee at the following address: Nominating and Corporate Governance Committee, Montauk Renewables, Inc., 5313 Campbells Run Road, Suite 200, Pittsburgh, PA 15205, Attn: Chief Legal Officer and Secretary, generally not less than 90 nor more than 120 calendar days prior to the first anniversary of the date on which the Company held the preceding year’s annual meeting of stockholders. Submissions must include, among other things, the full name of the proposed candidate, a description of the proposed candidate’s business experience for at least the previous five years, the number of Company securities owned by the candidate, complete biographical information, including a completed questionnaire, in the form provided by the Chief Legal Officer and Secretary of the Company, with respect to the identity and background of the proposed candidate, a description of the proposed candidate’s qualifications as a director, and such other information as required by our Bylaws. Any such submission must be accompanied by the written consent of the proposed candidate to be named as a nominee and to serve as a director, if elected.

Compensation Committee Interlocks and Insider Participation

None of our directors who serve as a member of our Compensation Committee is or has at any time during the past year been an officer or employee of the Company. None of our executive officers currently serves, or in the past year has served, as a member of the board of directors or compensation committee of any other entity that has one or more executive officers serving on the board of directors or compensation committee.

PROPOSAL NO. 2

RATIFICATION OF THE APPOINTMENT OF GRANT THORNTON LLP AS INDEPENDENT AUDITOR

Grant Thornton LLP served as our independent registered public accounting firm for the year ended December 31, 2022 and has been selected by the Audit Committee of the Board as our independent registered public accounting firm for the year ending December 31, 2023. The Audit Committee has further directed that management submit the selection of its independent registered public accounting firm for ratification by the stockholders at the Annual Meeting. Representatives of Grant Thornton LLP are expected to be present at the Annual Meeting. They will have an opportunity to make a statement if they so desire and will be available to respond to appropriate questions.

Neither our Bylaws nor other governing documents or law require stockholder ratification of the selection of Grant Thornton LLP as our independent registered public accounting firm. However, management, at the direction of the Audit Committee of the Board, is submitting the selection of Grant Thornton LLP to the stockholders for ratification as a matter of good corporate practice. If the stockholders fail to ratify the selection, the Audit Committee will reconsider whether to retain Grant Thornton. Even if the selection is ratified, the Audit Committee in its discretion may direct the appointment of different independent auditors at any time during the year if the Audit Committee determines that such a change would be in the best interests of the Company and its stockholders.

THE BOARD UNANIMOUSLY RECOMMENDS A VOTE “FOR” THE RATIFICATION OF THE SELECTION OF GRANT THORNTON AS OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR THE YEAR ENDING DECEMBER 31, 2023

All amounts have been determined in accordance with Rule 13d-3 under the Exchange Act. A person has beneficial ownership of shares if he or she has the power to vote or dispose of such shares. This power can be exclusive or shared, direct or indirect. For purposes of this table, a person or group of persons is deemed to have “beneficial ownership” of any shares of common stock which such person has the right to acquire within 60 days of April 14, 2023. For purposes of computing the percentage of outstanding shares of common stock held by each person or group of persons named above, any security which such person or persons has or have the right to acquire within 60 days of April 14, 2023 is deemed to be outstanding, but is not deemed to be outstanding for the purpose of computing the percentage ownership of any other person.

Because of the arrangements in the Consortium Agreement, the parties will be deemed to have formed a “group” for purposes of Section 13(d)(3) of the Exchange Act, and such “group” will be deemed to beneficially own an aggregate of 74,900,640 shares of our common stock, which represents approximately 52.1% of the total number of shares of our common stock issued and outstanding. As a result, we are a “controlled company” within the meaning of the Nasdaq corporate governance standards.

Long-Term Equity Compensation

Montauk Renewables, Inc. Equity and Incentive Compensation Plan

The Board adopted the Plan in January 2021. The Plan provides the Board and the Compensation Committee with the authority to cash and equity-based awards in the forms of restricted stock, restricted stock units, stock options, performance awards and other awards. On January 28, 2021, the Board approved, in accordance with the Plan, the grant of 264 RSUs (with each representing one share of common stock) to all then actively employed personnel in the Company, including our NEOs, and our NEOs also received RS and Option awards as follows: Mr. McClain—695,889 shares of RS and an Option to purchase 313,455 shares of common stock; Mr. Ciroli—317,121 shares of RS and an Option to purchase 149,508 shares of common stock; and Mr. Van Asdalan—354,161 shares of RS and an Option to purchase 159,827 shares of common stock. The RS, RSUs and Option awards are subject to vesting requirements and continued service, as well as the terms and conditions of the Plan and related award agreements.

For RS awards made to our NEOs on January 28, 2021, the vesting schedule is detailed below in the Outstanding Equity Awards at Fiscal Year-End 2022 section of this proxy statement. All Option and RSU grants to our NEOs were subject to a one year vesting period and vested on January 28, 2022. The RS awards continue to vest subject to continued employment over the applicable vesting period and provided that, in the event of a termination of employment without cause by the Company, or due to death, disability, or retirement (as defined in the award agreement), the awards will vest; provided, however, that in the case of retirement, the awards will pro rata vest. The RS awards also provide that, if the awards are assumed in a change in control transaction, such awards will vest if a “double-trigger” occurs (i.e., a change in control transaction plus a termination of employment without cause during the remaining vesting term of the awards).

The RS, Option and RSU award agreements also include restrictive covenants, including one-year non-compete and non-solicit covenants during employment and for one year thereafter, confidentiality and protection of intellectual property covenants.

401(k) Plan

The NEOs participate in a 401(k) plan (the “401(k) Plan”), under which fixed annual contributions are made for the account of each participating employee. After two months of employment, an employee is eligible to participate in the 401(k) Plan. Upon reaching eligibility, the Company automatically funds a contribution of 3% of eligible compensation on the employee’s behalf and will match 50% of the employee’s first 4% voluntary deferral.

Stock Ownership Guidelines

We have adopted Stock Ownership Guidelines (the “Stock Guidelines”) for directors, executives and key managers to effectively link the interests of management and our stockholders and to promote an ownership culture throughout our organization. We believe that Company stock should be acquired and held in quantities that encourage management to make decisions and take actions that will enhance Company performance and increase its value. The Stock Guidelines were adopted by the Board in January 2021 and are periodically reviewed by the Compensation Committee. Employees have the later of five years from the effective date of the Stock Guidelines or five years from the date they become subject to the Guidelines to acquire the requisite holdings.

Our current Stock Guidelines are:



Role	FY 2022 Multiple of Base Salary or Director Fee (1)
President and CEO		4X
All Other Executive Officers Reporting to the President and CEO		3X
Non-Employee Directors		3X

(1)	Company stock owned outright, vested and unvested RS and RSUs, and Options count toward fulfilling the Stock Guidelines.

CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS

Certain Transactions

Transaction Implementation Agreement

On November 6, 2020, we entered into a transaction implementation agreement with MNK (as amended, the “Transaction Implementation Agreement”). The Transaction Implementation Agreement (“TIA”) governs the overall terms of the relationship between the Company and MNK following the distribution by MNK on January 26, 2021 of all of the outstanding shares of Montauk common stock as a pro rata dividend to holders of MNK’s ordinary shares (the “Distribution”) and the completion of the IPO.

Pursuant to the TIA, the Company executed several reorganization transactions that resulted in the Company owning all of the assets and entities through which MNK’s business and operations were conducted. Generally, the TIA provides for the termination of all intercompany agreements and accounts between the Company and its subsidiaries, on the one hand, and MNK, on the other hand, other than with respect to the promissory note described below, and was accompanied by a mutual release of claims between MNK and the Company for all matters arising prior to the Distribution. In addition, the TIA governs the treatment of access to information, rights to privileged information and record retention. Pursuant to the TIA, we paid MNK $796,000 in Fiscal 2021 and $52,000 in Fiscal 2022.

Promissory Note with MNK

In connection with the closing of the IPO and the Distribution, on January 26, 2021, the Company entered into a Loan Agreement and Secured Promissory Note (the “Initial Promissory Note”) with MNK. MNK is currently an affiliate of the Company and certain of the Company’s directors and executive officers are also directors and executive officers of MNK. Pursuant to the Initial Promissory Note, the Company advanced a cash loan of $5,000,000 to MNK for MNK to pay its dividends tax liability arising from the Distribution under the South African Income Tax Act, 1962 (Act No. 58 of 1962), as amended. On February 22, 2021, the Company and MNK entered into an Amended and Restated Promissory Note (the “Amended Promissory Note”) to increase the principal amount of the loan to a total of $7,140,000 in the aggregate. On December 22, 2021, the Company and MNK entered into the Second Amended and Restated Promissory Note (the “Second Amended Promissory Note”) to increase the principal amount of the loan to a total of $8,940,000, in the aggregate, in accordance with the Company’s obligations set forth in the TIA. On December 22, 2022, Montauk entered into the First Amendment to the Second Amended Promissory Note, by and between Montauk and MNK (the “First Amendment”), which extended the maturity date of the loan under the Second Amended Promissory Note from December 31, 2022 to June 30, 2023. All other terms of the MNK Loan Agreement remain unchanged.

Administrative Services Agreement with HCI Managerial Services Propriety Limited

Mr. Copelyn is the chief executive officer of HCI and Mr. Govender is the executive director of HCI. Messrs. Copelyn and Govender both serve on the board of directors of HCI Managerial Services (Pty) Limited, a subsidiary of HCI (“HCI Managerial”).

Pursuant to our agreement with HCI Managerial, we pay a monthly fee of R20,000, plus applicable VAT thereon, for such services.

Policies and Procedures for Related Party Transactions

We adopted a written policy relating to the approval of related party transactions. A “related party transaction” is a transaction, arrangement or relationship, or series of similar transactions, arrangements or relationships, in which we participate (whether or not we are a party) and a related party has a direct or indirect material interest in such transaction. Our Audit Committee reviews and approves or disapproves, or ratifies, all relationships and related party transactions between us and (1) our directors, director nominees or executive officers, (2) more than 5% owners of our common stock, (3) any immediate family member of any person specified in (1) and (2) above, and (4) any firm, corporation or other entity in which any person specified in (1), (2) or (3) above is employed or is a partner or principal or in a similar position, or in which such person has more than a 5% beneficial ownership interest. The Audit Committee reviews all related party transactions reported to it and, where the Audit Committee determines that such transactions are in our best interests and the best interests of our stockholders, approves such transactions in advance of such transactions being given effect.

As set forth in the related party transaction policy, in the course of its review and approval or ratification of a related party transaction, the Audit Committee, in its judgment, considers all relevant factors, including but not limited to the benefits to us, the impact on the related party, the availability and terms of comparable products or services and other various factors enumerated in the policy.

Montauk Renewables, Inc.| 2023 Proxy Statement – 21

Any member of the Audit Committee who is a related person with respect to a transaction under review will not be permitted to participate in the discussions or approval or ratification of the transaction. However, such member of the Audit Committee will provide all material information concerning the transaction to the Audit Committee. Our policy also provides the Audit Committee with the discretion to pre-approve certain transactions.

The Board and the Audit Committee, in the case of the promissory note described above, approved such transaction.

If you are a stockholder of record, you can revoke your proxy by submitting another properly completed proxy card to the South African registrar as described above. In each case, you should revoke your proxy prior to 15:00 South African Time on May 29, 2023.

If you attend the Annual Meeting and vote online, this will revoke your proxy. Attending the meeting will not, by itself, revoke your proxy.

Who tabulates the votes?

Votes are tabulated by Carideo Group, which acts as the inspector of election, who will separately count: (1) for the proposal to elect the director nominees, votes “For,” “Withhold” and broker non-votes (Proposal No. 1) and with respect to other proposals, votes “For” and “Against,” as well as abstentions (Proposal No. 2).

Abstentions will be counted towards the vote total for Proposal No. 2, and will have the same effect as “Against” votes. Broker non-votes have no effect and will not be counted towards the vote total for Proposal No. 1.

Additional Information

What are “broker non-votes”?

If your shares are held by a broker (i.e., in “street name”), the broker will ask you how you want your shares to be voted. If you give the broker voting instructions, your shares will be voted accordingly. If you do not give voting instructions to your broker, one of two things can happen, depending on the type of proposal. For the ratification of the election of independent auditors (Proposal No. 2), which is considered a “routine” matter, the broker may vote your shares in its discretion. By contrast, brokers do not have the discretion to vote your shares for the election of directors (Proposal No. 1), because this proposal is a “non-routine” matter. If you do not provide voting instructions to your broker for non-routine matters, the broker cannot vote your shares on such matters. This is called a “broker non-vote.” Broker non-votes have no effect and will not be counted with respect to non-routine matters submitted for a stockholder vote.

How many votes are required for the approval of each proposal?

•

Proposal No. 1 – For the election of directors, the two nominees receiving the most “For” votes from the holders of shares present by person or represented by proxy and entitled to vote on the election of directors will be elected. Accordingly, only votes “For” will affect the vote outcome (and a “withhold” vote will have no effect on the vote outcome).

•

Proposal No. 2 – To ratify the selection of Grant Thornton LLP as our independent registered public accounting firm for the year ending December 31, 2023, the proposal must receive “For” votes from the holders of a majority of shares present by person or represented by proxy and entitled to vote on the matter. Abstentions have the same effect as an “Against” vote.

What constitutes a quorum?

A quorum of stockholders is necessary to hold a valid Annual Meeting. A quorum is established if the holders of a majority in voting power of the shares of common stock issued and outstanding and entitled to vote are present in person or represented by proxy at the Annual Meeting. Abstentions and broker non-votes will be counted towards the quorum requirement.

Where can I find the results of the voting of the Annual Meeting?

We will announce preliminary voting results at the Annual Meeting. We will disclose the final voting results in a Current Report on Form 8-K, which we expect to file within four (4) business days after the Annual Meeting.

What are the procedures for submitting a stockholder proposal or nomination for the 2024 Annual Meeting?

Requirements for stockholder proposals to be brought before an annual meeting.

Our Bylaws provide that, for stockholder director nominations or other proposals to be considered at an annual meeting, the stockholder must give timely notice thereof in writing to our Secretary at Montauk Renewables, Inc., 5313 Campbells Run Road, Suite 200, Pittsburgh, PA 15205. To be timely for the 2024 Annual Meeting of Stockholders, a stockholder’s notice must be delivered to or mailed and received by our Secretary at our principal executive offices between February 6, 2024 and March 7, 2024; provided that if the date of that annual meeting of stockholders is scheduled for a date more than 30 calendar days prior to or more than 30 calendar days after the anniversary of the preceding year’s annual meeting, you must deliver the required notice on the later of the 90th calendar day prior to such annual meeting and the 10th calendar day following the day on which public disclosure of that meeting date is first made. A stockholder’s proposal must also set forth the information required by our Bylaws.

In addition to satisfying the requirements under our bylaws, to comply with the universal proxy rules, stockholders who intend to solicit proxies in support of director nominees other than the Company’s nominees must provide notice that sets forth the information required by Rule 14a-19 under the Exchange Act (including a statement that such stockholder intends to solicit the holders of shares representing at least 67% of the voting power of the Company’s shares entitled to vote on the election of directors in support of director nominees other than Montauk’s nominees), which notice must be postmarked or transmitted electronically to us at our principal executive offices no later than 60 calendar days prior to the first anniversary date of this year’s annual meeting. If the date of the 2024 Annual Meeting of Stockholders is changed by more than 30 calendar days from the anniversary of the Annual Meeting, then notice must be provided by the later of 60 calendar days prior to the date of the 2024 Annual Meeting of Stockholders or the 10th calendar day following the day on which public announcement of the date of the 2024 Annual Meeting of Stockholders is first made. Accordingly, for the 2024 Annual Meeting of Stockholders, we must receive such notice no later than April 6, 2024.

Additional Information

Requirements for stockholder proposals to be considered for inclusion in our proxy materials.

Stockholder proposals submitted pursuant to Rule 14a-8 under the Exchange Act, and intended to be presented at the 2024 Annual Meeting of Stockholders must be received by us not later than December 27, 2023 in order to be considered for inclusion in our proxy materials for that meeting.

Householding Information

We have adopted “householding,” an SEC approved procedure that permit companies and intermediaries (e.g., brokers) to satisfy the delivery requirements for Notices of Internet Availability of Proxy Materials or other Annual Meeting materials with respect to two or more stockholders sharing the same address and last name by delivering a single Notice of Internet Availability of Proxy Materials or other Annual Meeting materials addressed to those stockholders. A single Notice will be delivered to multiple stockholders sharing an address unless contrary instructions have been received from the affected stockholders. This procedure saves printing and postage costs by reducing duplicative mailings. Stockholders who participate in householding will continue to receive separate proxy cards. If you wish to opt out of householding and would prefer to receive a separate Notice, please notify your broker or submit a written request to: Chief Legal Officer and Secretary, Montauk Renewables, Inc., 5313 Campbells Run Road, Suite 200, Pittsburgh, PA 15205, (412) 747-8700. Once you have received notice from your broker that they will be “householding” communications to your address, “householding” will continue until you are notified otherwise or until you revoke your consent. Similarly, stockholders who currently receive multiple copies of the Notice at their addresses and would like to request “householding” of their communications should submit such request in accordance with the above instructions.

There will be no “householding” of communications for stockholders on the South African register.
