Key Terms

broker non-votes, householding, Convertible Senior Notes, Adjusted EBITDA, +2 more

6 terms

broker non-votes financial

"In the absence of instructions, the shares are viewed as being subject to “broker non-votes.”"

Broker non-votes occur when a brokerage firm is unable to vote on a shareholder’s behalf during a company election or decision because the shareholder has not given specific voting instructions, and the broker is not allowed or chooses not to vote on certain matters. They are important because they can affect the outcome of votes, especially when the results are close, by effectively reducing the total number of votes cast.

householding financial

"This process, which is commonly referred to as “householding,” potentially provides extra convenience for stockholders and cost savings for companies."

Convertible Senior Notes financial

"we issued $155.0 million aggregate principal amount of 4.75% Convertible Senior Notes due 2030"

Convertible senior notes are a type of loan that a company issues to investors, which can be turned into company shares later on. They are called "senior" because they are paid back before other debts if the company runs into trouble. This allows investors to earn interest like a loan but also have the chance to own part of the company if its value rises.

Adjusted EBITDA financial

"The Company reported revenue of $622.2 million and Adjusted EBITDA of $244.2 million for the year."

Adjusted EBITDA is a way companies measure how much money they make from their core operations, like running a business, by removing certain costs or income that aren’t part of regular business activities. It helps investors see how well a company is doing without distractions from unusual expenses or gains, making it easier to compare companies or track performance over time.

Beneficial owner financial

"each person who is known to the Company to be the beneficial owner of more than 5% of the outstanding shares"

A beneficial owner is the person who ultimately owns or controls a financial asset or property, even if their name isn't directly on official documents. Think of it like someone who secretly holds the keys to a safe deposit box—others may appear to have access, but the true owner is the one who benefits from what's inside. Identifying beneficial owners helps ensure transparency and prevent illegal activities like money laundering or fraud.

total stockholder return financial

"continued to utilize performance equity based upon total stockholder return benchmarked against pre-determined thresholds"

Total stockholder return is the percentage gain or loss an investor would have experienced over a period from both changes in a stock’s price and any cash payouts such as dividends, assuming those payouts are reinvested in the stock. It matters because it shows the complete financial outcome of owning a share — like measuring both a house’s change in sale value and the rent you collected — and lets investors fairly compare performance across companies and time.

PROXY STATEMENT

INFORMATION CONCERNING SOLICITATION AND VOTING

The enclosed proxy is solicited on behalf of the Board of Directors (the “Board”) of Solaris Energy Infrastructure, Inc. (the “Company”) for use at the Company’s 2026 Annual Meeting of Stockholders (the “Annual Meeting”) to be held May 15, 2026, at 9:00 a.m. local time, or at any adjournment or postponement thereof, for the purposes set forth herein and in the accompanying Notice of Annual Meeting of Stockholders. We expect that the Annual Meeting will be held at the principal executive offices of Solaris Energy Infrastructure, Inc., located at 9651 Katy Freeway, Suite 300, Houston, Texas 77024. The telephone number at that address is (281) 501-3070.

The Company has elected to take advantage of the “Notice and Access” rules adopted by the U.S. Securities and Exchange Commission (the “SEC”), which allow public companies to deliver a Notice of Internet Availability of Proxy Materials (“Notice of Internet Availability”) and provide Internet access to the proxy materials and annual report to their stockholders. The use of Notice and Access generates significant cost savings for the Company.

In lieu of paper copies of the proxy statement and other materials, most of our stockholders will receive a Notice of Internet Availability containing instructions on how to access the proxy materials and annual report and vote online. Please follow the instructions on the Notice of Internet Availability for requesting paper or e-mail copies of our proxy materials and annual report. If you choose to receive future proxy materials by e-mail, you will receive an e-mail next year with instructions with links to the proxy materials and to the proxy voting site. Your election to receive proxy materials by e-mail will remain in effect until you instruct us otherwise. Choosing to receive your future proxy materials by e-mail will save the Company the cost of printing and mailing documents to you.

Most stockholders have a choice of granting their proxies by telephone, over the Internet or by using a traditional proxy card or voting instruction form. You should refer to your proxy or voting instruction card to see which options are available to you and how to use them. The Internet and telephone voting procedures are designed to authenticate stockholders’ identities and to confirm that their instructions have been properly recorded. Please do not return the Notice of Internet Availability. The Notice of Internet Availability is not a valid proxy.

The cost of preparing, assembling and mailing the proxy materials and of reimbursing brokers, nominees and fiduciaries for the out-of-pocket and clerical expenses of transmitting copies of the proxy materials to the beneficial owners of shares held of record by such persons, will be borne by the Company. Proxies may be solicited by telephone, electronic communication, or personal communication by employees of Broadridge and the Company. Employees of the Company will not be compensated separately for these efforts. These proxy solicitation materials are being mailed and made available at www.proxyvote.com beginning on April 1, 2026 to all stockholders entitled to vote at the Annual Meeting.

A stockholder of record giving a proxy pursuant to this solicitation (including via telephone or via the Internet) may revoke it at any time before the Annual Meeting by delivering to the Corporate Secretary of the Company a written notice of revocation or a valid proxy (including via telephone or via the Internet) bearing a later date or by attending the Annual Meeting and voting in person. Stockholders who hold their shares through a broker, bank or other designee should refer to the instructions they receive from that broker, bank or other designee to determine how to revoke their proxy or change their vote.

Deadline for Receipt of Stockholder Proposals and Nominees

Pursuant to regulations of the SEC, in order to be included in the Company’s Proxy Statement for its 2027 Annual Meeting of Stockholders, stockholder proposals must meet all the requirements of Rule 14a-8 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and be received at the Company’s principal executive offices, 9651 Katy Freeway, Suite 300, Houston, Texas 77024, Attention: Corporate Secretary, no later than December 2, 2026. In addition, the Company’s Amended and Restated Bylaws, as amended from time to time (the “Amended and Restated Bylaws”) provide that any stockholder who desires either to bring a stockholder proposal (other than precatory (non-binding) proposals presented under and in compliance with

TABLE OF CONTENTS

Rule 14a-8 of the Exchange Act) before an annual meeting of stockholders or to present a nomination for a director on the Board (a “Director”) at an annual meeting of stockholders must give advance notice to the Corporate Secretary of the Company with respect to such proposal or nominee. The Company’s Amended and Restated Bylaws generally require that written notice be received by the Corporate Secretary of the Company at the Company’s principal executive offices not less than 90 days nor more than 120 days prior to the anniversary of the preceding year’s annual meeting of stockholders and contain certain information regarding the stockholder desiring to present a proposal or make a nomination and, in the case of a nomination, information regarding the proposed Director nominee. For the 2027 Annual Meeting of Stockholders, the Corporate Secretary of the Company must receive written notice on or after January 15, 2027, and on or before February 14, 2027, respectively. However, in the event that the date of the 2027 Annual Meeting of Stockholders is scheduled for a date that is more than 30 days before or more than 60 days after May 15, 2027, such notice by the stockholder must be received by the Corporate Secretary no later than the 10^th day following the day on which public announcement of the date of the 2027 Annual Meeting of Stockholders is first made by the Company. A copy of the Company’s Amended and Restated Bylaws is available upon request from the Corporate Secretary of the Company. In addition to satisfying the deadlines in the notice procedures of our Amended and Restated Bylaws as set forth above, a stockholder who intends to solicit proxies in support of nominees submitted under the notice procedures in our Amended and Restated Bylaws and Rule 14a-19 of the Exchange Act for our 2027 Annual Meeting of Stockholders must provide the notice required under Rule 14a-19 under the Exchange Act to the Corporate Secretary of the Company at the Company’s principal executive offices no later than March 16, 2027.

Record Date, Shares Outstanding and Voting

The Company’s Class A common stock, par value $0.01 per share (the “Class A Common Stock”), and Class B common stock, $0.00 par value per share (the “Class B Common Stock,” and together with the Class A Common Stock, the “Common Stock”), are the only classes of securities that entitle holders to vote generally at meetings of the Company’s stockholders. Only stockholders of record at the close of business on March 20, 2026 (the “record date”) are entitled to notice of, and to vote at, the Annual Meeting. At the record date, 58,138,451 shares of our Class A Common Stock and 15,349,651 shares of our Class B Common Stock were issued and outstanding and entitled to be voted at the Annual Meeting. The presence, in person or by proxy, of stockholders holding a majority of the shares of the Common Stock entitled to vote will constitute a quorum for the Annual Meeting, therefore, 36,744,052 shares of our Common Stock (regardless of class) need to be represented in person or by proxy for us to hold the Annual Meeting.

Every stockholder is entitled to one vote for each share held with respect to each matter, including the election of Directors, which comes before the Annual Meeting. Stockholders do not have the right to cumulate their votes in the election of Directors. If a stockholder specifies how the proxy is to be voted with respect to any of the proposals for which a choice is provided, the proxy will be voted in accordance with such specifications. If a stockholder signs and dates their proxy but does not specify a choice with respect to such proposals, the proxy will be voted (i) “FOR” all Director nominees named in this Proxy Statement (Proposal 1), (ii) “FOR” the ratification of the appointment of BDO USA, P.C. (“BDO USA”) as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2026 (Proposal 2) and (iii) “FOR” the advisory non-binding vote to approve the compensation of the Company’s Named Executive Officers (Proposal 3).

The plurality of the votes validly cast at the Annual Meeting is required to elect each Director nominee (Proposal 1). A ballot for a nominee that is marked “withheld” will not be counted as a vote cast. The affirmative vote of a majority of the voting power of the outstanding shares of Common Stock present in person or represented by proxy at the Annual Meeting and entitled to vote is required to ratify the appointment of BDO USA as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2026 (Proposal 2) and to approve on an advisory, non-binding basis the compensation of the Company’s Named Executive Officers (Proposal 3).

New York Stock Exchange (“NYSE”) rules permit brokers to vote for routine matters, such as the ratification of the appointment of BDO USA (Proposal 2), without receiving instructions from the beneficial owner of the shares. NYSE rules prohibit brokers from voting on the election of Directors (Proposal 1), the compensation of the Company’s Named Executive Officers (Proposal 3) and other non-routine matters without receiving instructions from the beneficial owner of the shares. In the absence of instructions, the shares are viewed as being subject to “broker non-votes.” “Broker non-votes” will be counted for quorum purposes (as

TABLE OF CONTENTS

they are present and entitled to vote on the ratification of BDO USA’s appointment (Proposal 2)), but will not affect the outcome of any other matter being voted upon at the Annual Meeting. Specifically, a broker or other nominee holding shares for a beneficial owner may not vote these shares in regard to the election of Directors (Proposal 1) and the advisory non-binding vote to approve the compensation of the Company’s Named Executive Officers (Proposal 3) without specific instructions from the beneficial owner.

The three Director nominees receiving the highest number of votes will be elected as Class III Directors. You may vote for all the Director nominees, withhold authority to vote your shares for all the Director nominees or withhold authority to vote your shares with respect to any one or more of the Director nominees. Withholding authority to vote your shares with respect to one or more Director nominees will have no effect on the election of the nominees in Proposal 1. Abstentions are treated as present and entitled to vote and thus, will be counted in determining whether a quorum is present. Abstentions will have the effect of a vote cast AGAINST Proposal 2 and Proposal 3.

“Householding” of Proxy Materials

The SEC has adopted rules that permit companies and intermediaries such as brokers to satisfy delivery requirements for proxy materials with respect to two or more stockholders sharing the same address by delivering a single copy of the proxy materials addressed to those stockholders. This process, which is commonly referred to as “householding,” potentially provides extra convenience for stockholders and cost savings for companies. The Company and some brokers use this process for proxy materials, delivering a single copy of the Notice of Internet Availability to multiple stockholders sharing an address unless contrary instructions have been received from the affected stockholders. Once you have received notice from your broker or the Company that they will be householding materials to your address, householding will continue until you are notified otherwise or until you revoke your consent. If, at any time, you no longer wish to participate in householding and would prefer to receive separate copies, or if you are receiving multiple copies and wish to receive only one, please notify your broker if your shares are held in a brokerage account or the Company if you hold shares registered in your name, and the Company will promptly undertake to carry out your request. If you hold shares in the Company directly, you can notify the Company by sending a written request to the Company at 9651 Katy Freeway, Suite 300, Houston, Texas 77024, or by telephone at (281) 501-3070.

Since the Company has the option to deliver cash in lieu of shares of Class A Common Stock upon exercise by a Solaris LLC Unit holder of its redemption right, beneficial ownership of Class B Common Stock and Solaris LLC Units is not reflected as beneficial ownership of shares of our Class A Common Stock for which such Solaris LLC Units and Class B Common Stock may be redeemed.

ELECTION OF DIRECTORS (PROPOSAL NO. 1)

Nominees. The three Class III Directors are to be elected at the Annual Meeting. Our Directors are divided into three classes serving staggered three-year terms. Class I, Class II and Class III Directors serve until our Annual Meetings of Stockholders in 2027, 2028 and 2029 (if elected at the Annual Meeting), respectively. Messrs. Burke and Yzaguirre and Mses. Argo and Brock are assigned to Class I. Messrs. Keenan and Walker and Ms. Durrett are assigned to Class II. Messrs. Giesinger, Teague and Zartler are assigned to Class III and are standing for election at the Annual Meeting. At each annual meeting of stockholders, Directors will be elected to succeed the class of Directors whose terms have expired. This classification of our Board could have the effect of increasing the length of time necessary to change the composition of a majority of the Board. In general, at least two annual meetings of stockholders will be necessary for stockholders to effect a change in a majority of the members of the Board. Each Director elected to the Board will hold office until his or her term expires or until his or her successor has been elected and qualified. Unless otherwise instructed, the proxy holders will vote the proxies received by them for the three Class III nominees named below, each of whom is presently a Director of the Company. In the event any of the nominees are unable or decline to serve as a Director at the time of the Annual Meeting, the proxies will be voted for any nominee who shall be designated by the present Board to fill the vacancy, unless the size of the Board is reduced. The proxies cannot be voted for a greater number of persons than the number of nominees named in this Proxy Statement. It is not expected that any nominee will be unable or will decline to serve as a Director. Biographical information regarding each nominee and each other Director is set forth below, as well as a summary of the experiences, qualifications, attributes or skills that caused the Nominating and Governance Committee and the Board to determine that each should serve as a Director of the Company. Each Director’s experience and understanding is evaluated in determining the overall composition of the Board.

On April 26, 2025, F. Gardner Parker, a member of the Board, passed away. Effective October 16, 2025, the Board appointed Amanda M. Brock as Co-Chief Executive Officer of the Company and as a Class I Director, with a term expiring at the 2027 annual meeting of stockholders, until she is either reelected or her successor is elected and qualified, or until her earlier death, resignation or removal, to fill the vacancy created by Mr. Parker’s passing.

Mr. Yzaguirre has also previously served as Chairman of the Public Utility Commission of Texas, on the Board of Directors of ERCOT, on the Board of Directors of the Texas Business Hall of Fame Foundation (including serving as its Chairman), and on the Board of Directors of the Texas Wildlife Association. He obtained a Bachelor of Business Administration degree from the University of Texas at Austin in 1983 and a Juris Doctorate degree with Honors from the University of Texas School of Law in 1986. We believe that Mr. Yzaguirre’s extensive experience, including that related to energy and financial industries, qualifies him to effectively serve as a member of the Board.

Vote Required

The plurality of the votes validly cast at the Annual Meeting is required to elect each Director nominee. The three Director nominees receiving the highest number of votes will be elected as Class III Directors. You may vote for all the Director nominees, withhold authority to vote your shares for all the Director nominees or withhold authority to vote your shares with respect to any one or more of the Director nominees. Withholding authority to vote your shares with respect to one or more Director nominees will have no effect on the election of the nominees in Proposal 1. Brokers do not have the authority to exercise their discretion with respect to this proposal if they do not receive instructions from the beneficial owner. Therefore, it is important that you vote your shares by proxy or in person at the Annual Meeting. If you submit a signed proxy card but do not give voting instructions as to how your shares of Common Stock should be voted, your shares will be voted in accordance with the recommendations of our Board stated in this Proxy Statement.

Recommendation

THE BOARD OF DIRECTORS RECOMMENDS A VOTE “FOR” THE ELECTION OF EACH OF THE CLASS III NOMINEES FOR DIRECTOR NAMED IN THIS PROXY STATEMENT.

Board Independence

The Board has determined that each of the following Directors is independent within the meaning of the listing standards of the NYSE:

Laurie H. Argo

James R. Burke

Edgar R. Giesinger

W. Howard Keenan, Jr.

A. James Teague

Ray N. Walker, Jr.

M. Max Yzaguirre

Mr. Zartler and Ms. Brock are not deemed independent because they serve as our Co-Chief Executive Officers, and Ms. Durrett is not deemed independent because she serves as our Chief Administrative Officer. Under the independence standards promulgated by the NYSE, the Board must have a majority of independent directors. The Board has evaluated the independence of the members of the Board under the independence standards promulgated by the NYSE. For a Director to qualify as independent, the Board must affirmatively determine that the Director has no material relationship with the Company, either directly or as a partner, stockholder or officer of an organization that has a relationship with the Company. In addition, the Board must assess each Director’s independence under the bright-line tests set forth in the NYSE standards. In conducting this evaluation, the Board and Nominating and Governance Committee considered transactions and relationships between each Director nominee or his or her immediate family and the Company, including personal relationships between Directors and management, to determine whether any such transactions or relationships were material and, therefore, inconsistent with a determination that each such Director nominee is independent. With respect to Mr. Keenan, the Board considered the fact that he is a manager of Yorktown X Associates LLC, the sole general partner of Yorktown X Company L.P., which is the sole general partner of Yorktown Energy Partners X, L.P., a significant Company stockholder. Mr. Keenan disclaims beneficial ownership of the shares held by Yorktown Energy Partners X, L.P., and the Board determined that this relationship is not inconsistent with a determination that Mr. Keenan is independent. With respect to Mr. Teague, the Board considered the fact that he is a director and Co-Chief Executive Officer of Enterprise LP, which is a customer of the Company. The Board evaluated the amount of revenue that the Company received from Enterprise LP during the year ended December 31, 2025 and Mr. Teague’s ownership in Enterprise LP and determined that this relationship is not inconsistent with a determination that Mr. Teague is independent.

Audit Committee. The Board has determined that all of the members of the Audit Committee meet the independence requirements under the NYSE and SEC rules and regulations applicable to audit committee members. Additionally, the Board has determined that each member of the Audit Committee is “financially literate” within the meaning of the applicable rules of the SEC and the listing standards of the NYSE and that Mr. Giesinger meets the requirements for being an “audit committee financial expert,” as that term is defined by applicable SEC rules. No member of the Audit Committee serves on the audit committee of more than three public companies.

Compensation Committee. The Board has determined that all of the members of the Compensation Committee are independent within the meaning of the listing standards of the NYSE applicable and as “non-employee directors” under Section 16 of the Exchange Act.

Nominating and Governance Committee. The Board has determined that all of the members of the Nominating and Governance Committee are independent within the meaning of the listing standards of the NYSE.

BOARD OF DIRECTORS, COMMITTEES OF THE BOARD OF DIRECTORS AND

MEETING ATTENDANCE

The Board met ten times and acted by unanimous written consent eight times during 2025. Each Director attended at least 75% of all meetings of the Board and the Committees of which each such Director was a member during 2025. Pursuant to the Company’s Corporate Governance Guidelines, Directors are encouraged to attend the Annual Meeting, and all Directors that were Directors as of the date of the 2025 Annual Meeting attended the 2025 Annual Meeting of Stockholders.

On April 26, 2025, Mr. Parker, a member of the Board, passed away. Effective October 16, 2025, the Board appointed Ms. Brock as Co-Chief Executive Officer of the Company and as a Class I Director, with a term expiring at the 2027 annual meeting of stockholders, until she is either reelected or her successor is elected and qualified, or until her earlier death, resignation or removal, to fill the vacancy created by Mr. Parker’s passing.

The primary function of the Board is oversight, which includes among other matters, oversight of the principal risk exposures to the Company. To assist the Board in this role, the Audit Committee periodically requests the Company’s internal auditor to conduct a review of enterprise risks associated with the Company. The internal audit firm reports its findings and assessments to the Audit Committee, which then reports the findings to the Board as a whole.

Mr. Zartler is our Chairman and has served as a Director of the Board since February 2017, our Chief Executive Officer since July 2018 and our Co-Chief Executive Officer since October 2025. The independent members of the Board believe the combined role of Chairman and Chief Executive Officer promotes unified leadership and direction for the Company, which allows for a clear focus for management to execute the Company’s strategy and business plans. As a Chief Executive Officer, the Chairman is best suited to ensure that critical business issues are brought before the Board, which enhances the Board’s ability to develop and implement business strategies. To ensure a strong and independent Board, all Directors of the Company, other than Mr. Zartler and Mses. Brock and Durrett, are independent. In addition, the Company’s Corporate Governance Guidelines provide that the Board will either designate one of its members as the Lead Independent Director or establish a procedure by which a Lead Independent Director is chosen to preside over the meetings of the non-management directors and to provide, in conjunction with the Chairman and Co-Chief Executive Officers, leadership and guidance to the Board. In April 2025, the Board determined that Mr. Giesinger would serve as the Lead Independent Director for executive sessions of the non-management directors going forward, and Mr. Giesinger has continued to serve in this position since that time. Mr. Giesinger’s duties as Lead Independent Director include serving as a liaison between the Chairman and the independent Directors of the Board and having the authority to call meetings of the independent Directors.

The Board has an Audit Committee, Compensation Committee and Nominating and Governance Committee. The Audit Committee, the Compensation Committee and the Nominating and Governance Committee are each currently comprised of three members. The charters of each of these Committees and the Company’s Corporate Governance Guidelines are available free of charge on the Company’s website at www.solaris-energy.com or by writing to the Company at: Solaris Energy Infrastructure, Inc., c/o Corporate Secretary, 9651 Katy Freeway, Suite 300, Houston, Texas 77024. The Board votes annually on the membership and chairmanship of all Committees.

Audit Committee. The Audit Committee currently consists of Edgar R. Giesinger (Chairman), Laurie H. Argo and M. Max Yzaguirre. The Audit Committee met four times and acted by written consent twice during 2025. The Audit Committee appoints and retains the Company’s independent registered public accounting firm, approves the fee arrangement and scope of the audit, reviews the financial statements and the independent registered public accounting firm’s report, considers comments made by the independent registered public accounting firm with respect to the Company’s internal control structure and reviews internal accounting procedures and controls with the Company’s financial and accounting staff. The Audit Committee also conducts the review of the non-audit services provided by the independent registered public accounting firm to determine their compatibility with its independence. Before the independent registered public accounting firm is engaged by the Company or its subsidiaries to render audit or non-audit services, the Audit Committee must pre-approve the engagement. Pre-approval of audit and non-audit services is not required if the engagement for the services is entered into pursuant to pre-approval policies and procedures established by the Audit Committee. The Chairman of the Audit Committee has the authority to grant pre-approvals, provided such approvals are within the pre-approval policy and presented to the Audit Committee at a subsequent meeting. The Audit Committee reviews the independent registered public accounting firm’s performance, qualification and quality control

TABLE OF CONTENTS

procedures and establishes policies for: (i) the pre-approval of audit and permitted non-audit services by the independent registered public accounting firm; (ii) the hiring of former employees of the independent registered public accounting firm; and (iii) the submission and confidential treatment of concerns from employees or others about accounting, internal controls, auditing or other matters.

The Audit Committee reviews with management the Company’s disclosure controls and procedures and internal control over financial reporting and the processes supporting the certifications of the Co-Chief Executive Officers and Chief Financial Officer. It also reviews with management and the Company’s independent registered public accounting firm the Company’s critical accounting policies. The Audit Committee reviews the Company’s annual and quarterly SEC filings and other related Company disclosures. The Audit Committee reviews the Company’s compliance with the Code of Business Conduct and Ethics as well as other legal and regulatory matters. The Audit Committee reviews related party transactions in accordance with the Company’s Related Persons Transactions Policy and applicable SEC guidelines.

In performing these duties, the Audit Committee has full authority to: (i) investigate any matter brought to its attention with full access to any officer, employee or advisor of the Company to meet with the Audit Committee or any advisors engaged by the Audit Committee; (ii) retain outside legal, accounting or other consultants to advise the Audit Committee; and (iii) request any officer or employee of the Company, the Company’s in-house or outside counsel, internal audit service providers or independent registered public accounting firm to attend a meeting of the Audit Committee or to meet with any members of, or consultants to, the Audit Committee.

Compensation Committee. The Compensation Committee currently consists of Ray N. Walker, Jr. (Chairman), Laurie H. Argo and A. James Teague. The Compensation Committee met three times and acted by unanimous written consent twice during 2025. The Compensation Committee generally, among other things, (i) establishes policies relating to the compensation of the non-employee Directors, officers and key management employees of the Company; (ii) reviews and approves the compensation of the non-employee Directors, officers and the Co-Chief Executive Officers; (iii) reviews and make recommendations to the Board with respect to incentive-compensation plans and equity-based plans; (iv) oversees the administration of the Company’s equity compensation plans; (v) reviews and approves periodically, but no less than annually, the Company’s compensation goals and objectives with respect to its officers, including oversight of the risks associated with the Company’s compensation programs; (vi) evaluates and approves post-service arrangements with management; and (vii) establishes and reviews periodically the Company’s perquisite policies for management and Directors. The Compensation Committee has determined that none of the Company’s compensation policies and practices are reasonably likely to have a material adverse effect on the Company.

In performing its duties, the Compensation Committee has ultimate authority and responsibility to engage and terminate any compensation consultant, legal counsel or other adviser (together “advisers”) to assist in determining appropriate compensation levels for the Co-Chief Executive Officers or any other member of the Company’s management and to approve the terms of any such engagement and the fees of any such adviser. In addition, the Compensation Committee may also request that any officer or other employee of the Company (including the Company’s senior compensation or human resources executives), the Company’s in-house or outside counsel, or any other person meet with any members of, or consultant to, the Compensation Committee. In addition to information provided by outside compensation consultants, the officers of the Company may also collect peer group compensation data for review by the Compensation Committee. Upon consultation with, and recommendations by, the Company’s Co-Chief Executive Officers, the Compensation Committee sets the compensation policy for Directors and executive officers as well as the Company as a whole.

Nominating and Governance Committee. The Nominating and Governance Committee currently consists of Laurie H. Argo (Chairperson), James R. Burke and Edgar R. Giesinger. The Nominating and Governance Committee acted unanimously in recommending the nomination of the Class III Directors in Proposal No. 1 to the Board for election by the stockholders at the Annual Meeting. The Nominating and Governance Committee met twice and acted by unanimous written consent twice during 2025. The Nominating and Governance Committee Charter sets forth the Nominating and Governance Committee’s responsibility to establish and periodically review the Company’s corporate governance principles and guidelines. These principles and guidelines address, among other matters, the size, composition and responsibilities of the Board and its Committees, including their oversight of management. The Nominating and Governance Committee also advises the Board with respect to the charter, structure and operation of each Committee of the Board. The Nominating

TABLE OF CONTENTS

and Governance Committee oversees the evaluation of the Board and officers of the Company and reviews and periodically reports to the Board on matters concerning Company succession planning. The Nominating and Governance Committee may retain outside consultants to advise it and has full access to any officer, employee or advisor of the Company to meet with the Nominating and Governance Committee or any advisors engaged by the Nominating and Governance Committee. The Nominating and Governance Committee has the ultimate authority and responsibility to engage or terminate any outside consultant, to identify Director candidate(s) and to approve the terms and fees of such engagement of any such consultant. The Nominating and Governance Committee may also request that any officer or other employee of the Company, the Company’s outside counsel, or any other person meet with any members of, or consultants to, the Nominating and Governance Committee.

The Company’s Board has charged the Nominating and Governance Committee with identifying individuals qualified to become members of the Board and recommending Director nominees for each Annual Meeting of Stockholders, including the recommendation of nominees to fill any vacancies on the Board. The Nominating and Governance Committee considers Director candidates suggested by its members, other Directors, officers and stockholders. Stockholders desiring to make such recommendations should timely submit the candidate’s name, together with biographical information and the candidate’s written consent to be nominated and, if elected, to serve to: Chairman, Nominating and Governance Committee of the Board of Directors of Solaris Energy Infrastructure, Inc., 9651 Katy Freeway, Suite 300, Houston, Texas 77024. To assist it in identifying Director candidates, the Nominating and Governance Committee is also authorized to retain, at the expense of the Company, third party search firms and legal, accounting, or other advisors, including for purposes of performing background reviews of potential candidates. The Nominating and Governance Committee provides guidance to search firms it retains about the particular qualifications the Board is then seeking.

All Director candidates, including those recommended by stockholders, are evaluated on the same basis. Candidates are selected for their character, judgment, business experience and specific areas of expertise, among other relevant considerations, such as the requirements of applicable law and listing standards (including independence standards), and a wide range of perspectives. The Board recognizes the importance of soliciting new candidates for membership on the Board and that the needs of the Board, in terms of the relative experience and other qualifications of candidates, may change over time. In determining the needs of the Board and the Company, the Nominating and Governance Committee considers the qualifications of sitting Directors and consults with the Board, the Chairman of the Board and certain other officers and, where appropriate, external advisors. All Directors are expected to exemplify the highest standards of personal and professional integrity and to assume the responsibility of challenging management through their active and constructive participation and questioning in meetings of the Board and its various Committees, as well as in less formal contacts with management. Director candidates, other than sitting Directors, are interviewed at the direction of the Nominating and Governance Committee, which may include (at the Nominating and Governance Committee’s direction) interviews by the Chairman of the Board, other Directors and certain other officers, and the results of those interviews are considered by the Nominating and Governance Committee in its deliberations.

Hedging, Pledging and Insider Trading Policies. The Company adopted an insider trading policy (“Insider Trading Policy”) governing the purchase, sale and other dispositions of the Company’s securities that applies to Directors, officers and employees, and to the Company itself in the repurchase of its own securities. We believe our Insider Trading Policy and repurchase procedures are reasonably designed to promote compliance with insider trading laws, rules and regulations, and the listing standards applicable to the Company. A copy of the Company’s Insider Trading Policy was filed as Exhibit 19.1 to its Annual Report on Form 10-K for the year ended December 31, 2024. The Company’s Insider Trading Policy prohibits hedging or monetization transactions, whether direct or indirect, involving the Company’s securities, including transactions involving Company-based derivative securities, regardless of whether the covered person is in possession of material, non-public information, except with respect to holding, exercising or settling of securities granted under the Company’s equity incentive plan. The Company’s Insider Trading Policy also prohibits the pledging of Company securities as collateral, subject to receipt of a waiver of this prohibition from the Audit Committee.

RELATED PARTY TRANSACTIONS

Our Board has adopted a written related party transactions policy, pursuant to which a “Related Party Transaction” is defined pursuant to Item 404 of Regulation S-K. Pursuant to this policy, our Audit Committee will review all material facts of all Related Party Transactions and either approve or disapprove entry into the Related Party Transaction, subject to certain limited exceptions. In determining whether to approve or disapprove entry into a Related Party Transaction, our Audit Committee shall take into account, among other factors, the following: (i) whether the Related Party Transaction is on terms no less favorable than terms generally available to an unaffiliated third-party under the same or similar circumstances and (ii) the extent of the Related Person’s interest in the transaction. Furthermore, the policy requires that all Related Party Transactions required to be disclosed in our filings with the SEC be so disclosed in accordance with applicable laws, rules and regulations. There have been no Related Party Transactions since January 1, 2025 where the procedures described above did not require review, approval or ratification or where these procedures were not followed.

In 2017, we entered into the following Related Party Transactions, which were ongoing during 2025: (i) in connection with the closing of the IPO, the Company entered into agreements with the Original Investors, that include (a) a registration rights agreement in which we agreed to register the sale of shares of our Class A Common Stock under certain circumstances; (b) the Solaris LLC Agreement pursuant to which each Original Investor has, subject to certain limitations, the right to cause Solaris LLC to acquire all or a portion of its Solaris LLC Units for, at Solaris LLC’s election, (x) shares of our Class A Common Stock at a redemption ratio of one share of Class A Common Stock for each Solaris LLC Unit redeemed, subject to the conversion rate adjustments for stock splits, stock dividends and reclassification and other similar transactions, or (y) an equivalent amount of cash, and, in connection therewith, a corresponding number of shares of Class B Common Stock will be cancelled; and (c) a tax receivable agreement that generally provides for the payment by the Company to the Original Investors and their permitted transferees of 85% of the net cash savings, if any, in U.S. federal, state and local income tax and franchise tax that the Company actually realizes (computed using simplifying assumptions to address the impact of state and local taxes) or is deemed to realize in certain circumstances in periods after the IPO; and (ii) administrative services arrangements with Solaris Energy Management, LLC and Blanco Air Services, LLC, companies owned by Mr. Zartler, the Chairman of the Board and Co-Chief Executive Officer of the Company, for the provision of certain services, including rent paid for office space, travel services, and other administrative support, to us at cost, which totaled approximately $700,000 and $300,000 for the fiscal years ending December 31, 2025 and 2024, respectively. The Company did not include any prepaid expenses and other current assets on the consolidated balance sheets as of December 31, 2025. As of December 31, 2024, the Company included $100,000 in related prepaid expenses and other current assets on the consolidated balance sheets. Additionally, as of each of December 31, 2025 and 2024, the Company included $100,000 of accruals to related parties in accrued liabilities on the consolidated balance sheet.

MER Acquisition

On July 9, 2024, we entered into a contribution agreement (the “Contribution Agreement”), with Solaris LLC, John A. Johnson, an individual resident of the State of Florida, John Tuma, an individual resident of the State of Texas, J Turbines, Inc., a Delaware corporation (“J Turbines”) and KTR Management Company, LLC, a Texas limited liability company (“KTR” and, together with J Turbines, the “Contributors”), pursuant to which the Contributors agreed to contribute (the “Contribution”) all of the issued and outstanding equity interests of Mobile Energy Rentals LLC, a Texas limited liability company (“MER”) to Solaris LLC, subject to terms and conditions set forth therein (the “MER Acquisition”), which closed on September 11, 2024 (the “Closing Date”). On the Closing Date, the Contribution was consummated and Solaris LLC received 100% of the issued and outstanding equity interests of MER, with aggregate consideration for the Contribution consisting of the issuance of 16,464,778 Solaris LLC units and an equal number of shares of Class B Common Stock with the fair value of the total purchase consideration transferred as approximately $323.1 million.

In connection with the MER Acquisition, we acquired a lease agreement for commercial real estate with KTR, which, as of December 31, 2025, owned 13.0% of the outstanding shares of our Class B Common Stock, representing 2.9% of the total voting shares. As of December 31, 2025, we recognized an operating lease right-of-use asset and a corresponding operating lease liability of $100,000, split between current and non-current portions, on the consolidated balance sheets. For the year ended December 31, 2025, we incurred $200,000 of rental expense related to the commercial real estate lease, included in cost of services on the consolidated statements of operations.

During the year ended December 31, 2025, the Company also purchased certain equipment from KTR for $2.0 million, included in property, plant and equipment, net on the consolidated balance sheets. The equipment was purchased at cost with no markup, representing the same price the Company would have paid in an arm’s-length transaction with an unrelated party.

Registration Rights

In connection with the MER Acquisition, the Contribution Agreement additionally provided for registration rights to J Turbines, KTR and/or such parties’ designees who received all or part of the equity consideration (“Holders”), pursuant to which we agreed to, on the terms set forth therein, register for resale the shares of Class B Common Stock received by the Holders as a result of the Contribution.

Blackrock

On May 2, 2025, we issued $155.0 million aggregate principal amount of 4.75% Convertible Senior Notes due 2030 (the “2030 Notes”). In connection with the issuance of the 2030 Notes, BlackRock Portfolio Management LLC (“BlackRock”), which held more than 5% of the total outstanding shares of our Common Stock at the time the 2030 Notes were issued, purchased an aggregate principal amount of $55.0 million of the 2030 Notes at the public offering price. The Audit Committee approved BlackRock’s participation in the 2030 Notes offering on April 30, 2025 in accordance with our related party transactions policy.

No such waivers were requested or granted in 2025.

TABLE OF CONTENTS

DIRECTOR COMPENSATION

We believe that attracting and retaining qualified non-employee Directors is critical to the future value growth and governance of our Company. We also believe that a significant portion of the total compensation package for our non-employee Directors should be equity-based to align the interests of directors with our stockholders.

As a result, we have maintained a non-employee Director compensation program since our IPO, which is reviewed annually by the Compensation Committee:

•

an annual cash retainer, valued at $100,000 for the Chairperson of the Audit Committee, $90,000 for the Chairperson of the Compensation Committee, $85,000 for Chairperson of the Nominating and Governance Committee, and $75,000 for all other non-employee Directors, plus an additional cash retainer of $20,000 for the Lead Independent Director, in each case, payable quarterly in arrears;

•	an annual equity-based award with an aggregate fair market value (determined on the date of grant) of $155,000 for all non-employee Directors; and

•

an annual equity-based award with an aggregate fair market value (determined on the date of grant) of $10,000 for each member of the Audit Committee (including the Chairperson) and $5,000 for each member of the Compensation Committee and Nominating and Governance Committee (including the respective Chairpersons).

We do not pay any additional fees for attendance at Board or Committee meetings, but we do reimburse each Director for reasonable travel and out-of-pocket expenses incurred to attend meetings and activities of the Board or its Committees. Directors who are also our employees will not receive any additional compensation for their service on the Board.

Mr. Zartler and Ms. Brock, our Co-Chief Executive Officers, and Ms. Durrett, our Chief Administrative Officer, do not receive any additional compensation for their service on the Board. The following table sets forth information regarding the compensation of our non-employee directors during the year ended December 31, 2025.

Compensation Objectives

Our executive compensation program is designed to achieve the following objectives:

•	Build shareholder value and create a shareholder mentality by aligning the interests of our NEOs with our investors;

•	Attract and retain a qualified and motivated management team by offering competitive industry opportunities and providing the majority of NEO compensation in the form of long-term incentives; and

•	Incentivize our NEOs and appropriately reward them for contributions that further the Company’s key short-term and long-term strategic goals and objectives.

2025 Industry and Business Overview

Fiscal year 2025 was a year of strong execution for the Company as our management team delivered growth in power generation capacity while sustaining our established logistics operations. The Company reported revenue of $622.2 million and Adjusted EBITDA of $244.2 million for the year. Power generation equipment served both energy and non-energy end markets, with data centers representing the largest exposure. Cash flows from logistics services supported the expansion of the power generation capacity. The Company made purchase commitments to grow operated capacity to 2.2 GW, while continuing to return capital to shareholders through dividends. For a more detailed definition of the non-GAAP financial measure of Adjusted EBITDA and a reconciliation of Adjusted EBITDA to our most directly comparable financial measure calculated in accordance with GAAP, please see Note 4, “Business Segments,” in the notes to our consolidated financial statements contained in our Annual Report on Form 10-K for the fiscal year ended December 31, 2025.

In 2026, the Company expects to maintain cash flow generation from its core operations and to continue deploying capital into power generation equipment. Demand for distributed power solutions is expected to support further growth, including under a new long-term contract for more than 500 MW that begins in January 2027. The management team completed a $748 million convertible bond issuance that retired existing term loan obligations and fully funds planned capital expenditures through 2028. We have raised first-quarter 2026 Adjusted EBITDA guidance to $72–77 million and established second-quarter guidance at $76–84 million.

TABLE OF CONTENTS

Compensation Best Practices. The Compensation Committee believes it is important to complement the compensation program with good governance and executive compensation best practices to further support the alignment between stockholders and executives as well as mitigating risks related to compensation levels. Key elements of the program in support of this objective are set forth in the chart below:


WHAT WE DO		WHAT WE DON’T DO
✔	Generally target cash-based compensation that is toward the lower half of our compensation peer group, relying heavily on long-term at-risk incentive based compensation	✘	No excessive perquisites

✔	Determine annual incentive compensation based upon the achievement of pre-established performance goals	✘	No guaranteed bonus or uncapped incentives

✔	Use compensation consultants, independent market data and peer groups to benchmark compensation decisions	✘	No pension plan

✔	Hold regular executive sessions of the Compensation Committee without management present	✘	No option repricing

✔	Base a portion of the long-term incentives upon achievement of certain performance objectives, including performance relative to peers	✘	No hedging, pledging or short-term/speculative trading of Company stock

✔	Annual compensation risk assessment	✘	No excise tax gross ups

✔	Engagement with stockholders regarding pay practices	✘	Utilize pay practices that incentivize decisions that are not in the best interests of the Company and its stockholders

Process for Setting Compensation and Role of Compensation Committee

Our Compensation Committee is comprised entirely of independent, non-employee members of the Board. As set forth in its charter, which is available at www.solaris-energy.com, the Compensation Committee is responsible for, among other things, reviewing and approving the plans, policies and programs of the Company with respect to the compensation for the Company’s executive officers and directors. The Board of Directors believes that the Company’s long-term success depends on the talent of our employees, and the executive compensation program plays a significant role in our ability to attract, retain and motivate the highest quality workforce. The Compensation Committee has designed our compensation program to directly link executive compensation to performance, in order to align the interests of the Company’s executive officers with those of its stockholders. The Compensation Committee evaluates, on an annual basis, industry-specific and general market compensation practices and trends to ensure that our program, and the compensation awarded to our NEOs, remains appropriately competitive while also furthering Company goals and initiatives.

Each year the Compensation Committee reviews the Company’s compensation program against market data and available compensation studies for the Company’s Peer Group (as defined below) as well as the industry in general (the “Market Data”). This review is conducted in light of the Company’s compensation philosophy and key short-term and long-term goals and initiatives. The Compensation Committee retains sole discretion to engage any other compensation consultants it deems necessary and appropriate to aid in their review in order to provide independent and objective market compensation data, conduct compensation analysis, recommend plan design changes and advise on compensation related risks. Any compensation consultant acts solely at the direction of the Compensation Committee and not at the direction of the Company’s management team.

TABLE OF CONTENTS

In 2025, the Compensation Committee engaged Pay Governance (the “Compensation Consultant”) to conduct (i) a competitive review of the compensation provided to the Company’s executive leadership team, including the NEOs, and (ii) a comprehensive market benchmarking review of compensation provided to the Company’s non-employee directors. The Compensation Committee has evaluated the Compensation Consultant’s independence pursuant to the requirements of NYSE and SEC rules and has determined that the Compensation Consultant does not have any conflicts of interest in advising the Compensation Committee. The Compensation Committee also reviews Market Data when reviewing the compensation of executives other than the NEOs. The Compensation Consultant compiles compensation surveys for review by the Compensation Committee and management. After review of the Compensation Consultant’s surveys, management provides recommendations of compensation for our directors and NEOs to the Compensation Committee. Such recommendations are generally based upon the data provided by the Compensation Consultant, Market Data and the performance of our management as a team. The Compensation Committee then reviews management’s recommendation with the ability to ask questions of management and may conduct an executive session as needed to discuss compensation.

With respect to the compensation of the NEOs, other than our Co-Chief Executive Officers, the Compensation Committee considers the recommendations of our Co-Chief Executive Officers. The Compensation Committee retains sole authority to establish the compensation of our Co-Chief Executive Officers after initial discussion with the Co-Chief Executive Officers and then independent deliberation in executive session.

Competitive Market Position and Peer Group

We believe that total compensation opportunities for our NEOs should be competitive with opportunities for executive officers in similar positions, with similar experience and with similar responsibilities to those in our Peer Group. We place a heavy emphasis on long-term incentives in the compensation program to align the interests of our management team with long-term shareholder value and to incentivize our team to achieve performance superior to competitors. For 2025, the Market Data provided to the Compensation Committee included compensation information from our Compensation Consultant relative to our Peer Group as well as other broad-based compensation survey sources. Although the Compensation Committee used the Market Data to inform its decisions regarding the form and amount of compensation provided to our NEOs in 2025, the Compensation Committee also considered other factors, including Company performance and strategic priorities, in determining final compensation levels.

For purposes of setting 2025 compensation, the peer group companies (our “Peer Group”) used by the Compensation Consultant and the Compensation Committee included the following companies:


NRG Energy, Inc.			Bloom Energy Corporation
Baker Hughes Company			Advanced Energy Industries, Inc.
NOV Inc.			Archrock, Inc.
Liberty Energy Inc.			Kodiak Gas Services, Inc.
IES Holdings, Inc.			Cactus, Inc.
Talen Energy Corporation			Powell Industries, Inc.
SPX Technologies, Inc.			Hut 8 Corp.

Our Peer Group was selected based on companies that broadly represent the end markets in which our business units serve, with an increasing focus on the power business. While some of these companies have larger market capitalizations or revenue, these companies represent the market in which we most directly compete for qualified and talented professionals.

Positive 2025 Say-on-Pay Vote Outcome

In 2025, we received approximately 99% stockholder support on our say-on-pay advisory vote. The Compensation Committee and Board of Directors considered the results of the advisory vote and in light of its overwhelming support, determined to keep the compensation philosophy and practices for 2025 consistent with prior years.

Objectives of Compensation

The goal of the Company’s compensation program is to help attract and retain qualified executive talent and to strengthen the alignment between executives and stockholders’ interests, thereby enhancing stockholder value.

TABLE OF CONTENTS

To achieve this goal, the Compensation Committee’s decisions are guided by the following principles: provide a competitive compensation package; relate compensation to the performance of the Company and the individual; and align employee objectives with the objectives of stockholders by encouraging executive stock ownership and focusing total compensation on long-term incentives. The Compensation Committee sets performance standards to support the Company's continued performance and position the Company competitively within our industry.

In order to achieve these objectives, the Compensation Committee has created a compensation package that combines current and deferred compensation with equity-based compensation. A significant portion of the target compensation for our NEOs is variable or “at risk,” meaning that it can be forfeited, and its value is dependent upon such factors as Company performance and our stock price. This structure requires executives to deliver strong results to realize the full value of their compensation, ensuring that at-risk elements remain in the money only through sustained high performance. A portion of the long-term incentives for our NEOs is performance based and tied to certain shareholder metrics, as discussed below under “LTIP Compensation.” The Company’s compensation program for executive officers consists of the following items:


	ELEMENT	PURPOSE	CHANGES FOR 2025
SHORT- TERM	Base Salary	To provide a consistent, minimum level of pay, sufficient to allow us to attract and retain executives with the appropriate skills and experience for their position	The only modifications reflected changes in roles, responsibilities, prevailing market conditions and data provided by the Compensation Consultant

	Annual Cash Incentive	To motivate and reward the achievement of our annual Company and Individual Performance goals: • 60% based on the achievement of quantifiable Company Performance Goals • 40% based on the achievement of Individual Performance	The only modifications reflected changes in roles, responsibilities, prevailing market conditions and data provided by the Compensation Consultant

LONG- TERM	Long-Term Incentive Award	To ensure retention and drive performance, while aligning the interests of our NEOs with those of our stockholders	None (continued to utilize performance equity based upon total stockholder return benchmarked against pre-determined thresholds as compared internally (Absolute TSR) and against a peer group (Relative TSR))

The Compensation Committee structures executive total direct compensation to emphasize performance through the annual incentive program and long-term incentives. The Compensation Committee recognizes that cash-based compensation is generally positioned below the median of the Peer Group and believes that the compensation mix should be weighted more heavily on long-term incentives to strike a balance promoting long-term returns without motivating or rewarding excessive or inappropriate risk-taking.

Elements of Compensation

Pay Mix

Our compensation program is designed so that the higher an executive’s position in the Company, the greater the percentage of compensation that is contingent on the Company’s performance through long-term incentives. The Company believes that having a significant portion of our NEOs’ compensation at risk better aligns their interests with the long-term interests of the Company and its stockholders. Because performance equity is a portion of the NEOs’ long-term incentives, a majority of our NEOs’ total target direct compensation for fiscal year 2025 was variable, at approximately 97% for one of our Co-Chief Executive Officers, Mr. Zartler, and averaging approximately 82% for our other NEOs.

TABLE OF CONTENTS

For purposes of this pay mix disclosure, Ms. Brock, our other Co-Chief Executive Officer, has been excluded because she joined the Company mid-year and received a one-time sign-on award that is not reflective of the total target mix of direct compensation under our compensation program.

The following charts illustrate the total target mix of direct compensation for Mr. Zartler and other NEOs for fiscal year 2025.

Base Salary

Each NEO’s base salary is a fixed component of compensation for performing specific job duties and functions. The Compensation Committee monitors and adjusts salaries for our NEOs over time as necessary to remain competitive with market rates for similarly situated officers at our Peer Group companies and to reflect any changes to the NEO’s role, duties and responsibilities. The base salaries for each NEO were as follows for 2025:


Name			2025 Base Salary
William A. Zartler			$450,000
Amanda M. Brock			$450,000
Kyle S. Ramachandran			$400,000
Christopher M. Powell			$375,000
Cynthia M. Durrett			$350,000
Christopher P. Wirtz			$265,000

Annual Incentive Award

Annual incentive awards are tied to the achievement of performance goals, which are based on both quantitative and qualitative measures as determined by the Compensation Committee in consultation with management. Each year the Compensation Committee, in consultation with management, reviews key short-term strategic initiatives to drive the annual cash-based incentive award. Annual short-term cash incentive awards are based upon targets for each NEO and awarded in light of certain key strategic initiatives and metrics, which are set by the Compensation Committee after review and consultation with management.

Target annual incentive award percentages for each of the NEOs are as follows: Mr. Zartler - 100%, Ms. Brock - 100%, Mr. Ramachandran - 90%, Mr. Powell - 75%, Ms. Durrett - 75% and Mr. Wirtz - 50%. The following key metrics were selected by the Compensation Committee to measure achievement of short-term Company goals: Financial and Operating Metrics (consisting of EBITDA, free cash flow, customer consistency, fully utilized systems deployed and market share), Strategic Initiatives (consisting of total shareholder return, contract tenor and total managed capacity) and Safety (collectively with the Financial and Operating Metrics and the Strategic Initiatives, the “Company Performance”) and Individual Performance. Company Performance accounts for 60% of the eligible annual incentive award with Individual Performance accounting for 40%. The

TABLE OF CONTENTS

Compensation Committee retains discretion to adjust these percentages and weighting based upon certain factors within their discretion. At the suggestion of our NEOs, the 2025 thresholds used for the Financial and Operating Metrics and the Strategic Initiatives accounted for approximately 83% of the Company Performance with Safety representing the remaining 17%.

The Compensation Committee maintains an element of discretion in the annual incentive for our NEOs in order to provide the Compensation Committee the flexibility to respond to specific events that are relevant to each NEO’s performance during the year in light of changing market conditions and responsibilities of each NEO. No payout percentage would be earned for a metric if the actual Company performance of that metric was below the threshold level set for that metric below. The Company Performance metrics, their related thresholds and weightings and actual performance for the year ended December 31, 2025 are set forth in the table below:

In 2025, our NEOs focused on capital returns in our business, including operating margins, utilization and performance of our equipment. Upon review of the results of the Company Performance and Individual Performance, the Compensation Committee approved the following annual incentive payouts for each NEO:


Name	Target Annual Incentive (% of Base Salary)	Target Annual Incentive ($)	Performance Achievement Level (% of Target)	Actual 2025 Annual Incentive Payout
William A. Zartler	100%	$450,000	183%	$825,000
Amanda M. Brock⁽¹⁾	100%	$450,000	46%	$206,000
Kyle S. Ramachandran	90%	$360,000	128%	$460,000
Christopher M. Powell	75%	$281,250	127%	$356,250
Cynthia M. Durrett	75%	$262,500	123%	$322,500
Christopher P. Wirtz	50%	$132,500	108%	$142,500

(1)	Ms. Brock joined the Company in October 2025. Consequently, Ms. Brock received a prorated annual incentive payout.

As discussed above, the Company delivered strong operational and strategic performance in 2025, resulting in above-target achievement under our annual incentive awards. In light of the Company’s significant growth during 2025 and the management team’s successful execution of several key strategic initiatives, the Compensation Committee determined that the resulting payouts appropriately reflect performance against the pre-established performance goals described above and are consistent with, and reinforce our commitment to, our pay-for-performance philosophy.

LTIP Compensation

The LTIP was adopted in May 2017 at the time of our IPO and amended at the 2023 Annual Meeting, and provides a means though which (a) we may attract, retain and motivate qualified persons as employees, directors and consultants, thereby enhancing the profitable growth of the Company and its affiliates and (b) persons upon whom the responsibilities of the successful administration and management of the Company and its affiliates rest, and whose present and potential contributions to the Company and its affiliates are of importance, can acquire and maintain stock ownership or awards the value of which is tied to the performance of the Company, thereby strengthening their concern for the Company and its affiliates.

TABLE OF CONTENTS

In 2025, following recommendations by the Co-Chief Executive Officers and review of Market Data, the Compensation Committee approved grants of time-based restricted stock awards (“RSAs”), which provides the grantee the right to receive dividends and vote the underlying shares but does not otherwise grant the NEO any other economic right until the time of vesting. If an NEO terminates service with the Company prior to vesting of the RSA, then, except in limited circumstances, such as a change of control, such RSAs are forfeited and return to the pool of shares available for grant under the LTIP. For 2025, the grant date value of RSAs for the NEOs as a group was initially set at approximately the 50^th-75^th percentile based on Market Data. For 2025, the RSAs awarded to the NEOs vest ratably over a three-year period.

A portion of our NEOs’ long-term incentive compensation is in the form of awards of performance-based restricted stock units (“PSUs”). The PSUs utilize Absolute Total Shareholder Return (“Absolute TSR”) and Relative Total Shareholder Return (“Relative TSR”) as metrics to measure performance. Relative TSR was measured against the Russell 2000 Index Oil Equipment and Services Subsector for award years 2023 and 2024 and against the Russell 2000 Index for award year 2025. The PSUs are subject to a three-year cycle and vest 25%, 25% and 50% in each of years 1, 2 and 3, respectively, for the Relative TSR PSUs and have a cliff vesting at the end of year 3 for the Absolute TSR PSUs. Given the Company’s strong TSR performance, which exceeded the maximum thresholds for the 2025 performance period under each of the PSU awards granted in 2023, 2024 and 2025, the third tranche of 2023 PSUs grants, the second tranche of the 2024 PSU grants and the first tranche of the 2025 PSU grants tied to Relative TSR and representing years 3, 2 and 1 of the overall performance period applicable to each award, respectively, vested at 200% of the target. The 2023 PSU grants tied to Absolute TSR also vested at 200% of the target.

PSUs provide the NEO the right to receive an amount ranging from 0% to 200% of the target number of PSUs granted based on both the Company’s Absolute and Relative TSR performance during the three-year performance period, subject to the continued employment of the NEO. PSUs will be eligible to receive dividends; however such dividends will not be paid until such time as the PSUs vest, if at all. The tables below shows the Company’s performance targets for the Absolute TSR and Relative TSR PSUs.

ABSOLUTE TSR:


Annualized Absolute TSR			Percentage of Target Award Earned
<5.0%			0%
5%			50%
10%			100%
≥15.0%			200%

*	Linear interpolation between performance levels will be used to determine the actual number of Absolute TSR PSUs that are earned for performance between achievement levels.

RELATIVE TSR:


Percentile Rank			Payout Percentage
≥75%			200%
50%			100%
25%			50%
<25%			0%

*	Linear interpolation between performance levels will be used to determine the actual number of Relative TSR PSUs that are earned for performance between achievement levels.

The Compensation Committee has considered the use of other forms of equity awards, including stock options and restricted stock units, and ultimately determined to use RSAs and PSUs given that they have a less dilutive effect than stock options. Additionally, the Compensation Committee determined that a approach based upon a mix of time-based vesting and performance incentives was appropriate given the Company’s desire to provide our NEOs with a long-term retention-focused award that also aligns the interests of our NEOs with those of our stockholders.

Employment, Severance and Change in Control Agreements

Employment Agreements

None of our NEOs have an employment agreement with the Company.

Change in Control Plan (2025)

The Company previously entered into Change in Control Severance Agreements, which are a form of participation agreement, under the Company’s Change in Control Severance Plan (the “CIC Plan”) with each of its NEOs. The CIC Plan was originally effective as of March 1, 2023 and remained in effect on December 31, 2025. The CIC Plan provided “double trigger” (meaning that both a termination of employment and a change in control must occur) benefits in the event the executive officer is terminated without “cause” or resigns for “good reason” during the 90 days prior to or within 12 months following a “change in control” as each such term is defined in the CIC Plan.

Pursuant to the terms of the CIC Plan, the level of severance benefit for which a participant is eligible is determined based on their designated tier in the CIC Plan (the “Tier”). As of December 31, 2025, the Tier levels for each of the Named Executive Officers was as follows:


Name			CIC Plan Tier Level
William A. Zartler			Tier 1
Amanda M. Brock			Tier 1
Kyle S. Ramachandran			Tier 2
Cynthia M. Durrett			Tier 2
Christopher M. Powell			Tier 2
Christopher P. Wirtz			Tier 2

The benefits provided to each NEO under the CIC Plan were based upon a review of the Market Data provided at the time the Change in Control Severance Agreements were entered into with each of the NEOs and such benefits include:

•

Severance payable in a lump sum in an amount equal to a multiplier of either 2.5 or 3.0 (based on the participant’s Tier) multiplied by the sum of (A) the participant’s annual base salary and (B) the participant’s target annual bonus for the year in which the termination date occurs, payable within sixty (60) days of the termination date;

•

An additional lump sum payment equal to 18 or 24 (based on the participant’s Tier) times the monthly premium for the participant’s and his or her dependents’ participation in the Company’s group health plans pursuant to the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended (“COBRA”), less the amount of employee contributions that would apply to such participation if the participant were an active employee, each determined as of the termination date, payable within sixty (60) days following the termination date;

•

Payment of any earned but unpaid annual bonus, if any, for the fiscal year preceding the fiscal year in which the termination date occurs, payable on the date when bonuses are paid to the Company’s executives for such fiscal year and in all events in the fiscal year that includes the termination date, plus an additional lump sum payment equal to a pro-rata portion of the target annual bonus that the participant was eligible to earn for the fiscal year in which the termination date occurs, based on the number of days the participant was employed during such fiscal year, payable within sixty (60) days following the termination date; and

•

Full vesting of all of the participant’s outstanding unvested restricted stock awards (and any other outstanding and unvested equity incentive awards); provided that, with respect to any PSUs, all performance goals or other vesting criteria will be deemed achieved at the greater of (i) 100% of the target number of PSUs or (ii) the actual achievement applicable performance objectives for such PSUs determined as of the termination date and all other terms and conditions will be deemed met.

TABLE OF CONTENTS

A participant’s rights to any severance benefits under the CIC Plan upon a qualifying termination were conditioned upon (i) the participant executing and not revoking a valid separation and general release of claims agreement in a form acceptable to the Company (the “Release”) and (ii) the Release becoming effective and irrevocable in accordance with its terms within sixty (60) days following the participant’s termination date.

Amended and Restated Executive Change in Control Severance Plan (2026)

Effective February 25, 2026, our Compensation Committee, acting pursuant to the authority delegated to it by the Board, approved an amendment to and restatement of the CIC Plan (as amended and restated, the “A&R CIC Plan”). The A&R CIC Plan supersedes and replaces the CIC Plan. As of the date of this proxy statement, each of our NEOs participates in the A&R CIC Plan.

If the Company terminates a Participant’s employment with the Company or any Affiliate without Cause or the Participant resigns for Good Reason during the 90 days prior to or 12-month period following a Change in Control, the Participant is eligible to receive the following Severance Benefits:

•

A lump sum payment in an amount equal to the Participant’s Severance Multiplier multiplied by the sum of (A) the Participant’s Base Pay, (B) the greater of (1) the Participant’s target annual bonus for the fiscal year in which the termination date occurs or (2) the Participant’s actual bonus for the fiscal year preceding the fiscal year in which the termination date occurs, and (C) an amount equal to the grant date fair value (determined in accordance with FASB ASC Topic 718) of all equity awards granted to the Participant during the fiscal year in which the termination date occurs (or, if such equity awards have not yet been granted, the grant date fair value of all equity awards granted to the Participant during the fiscal year preceding the fiscal year in which the termination date occurs), payable on the next regularly scheduled payroll date following the release effective date but in no event later than sixty (60) days following the termination date;

•

Payment of any earned but unpaid annual bonus, if any, for the fiscal year preceding the fiscal year in which the termination Date occurs, payable on the date when bonuses are otherwise paid to the Company’s executives for such fiscal year and in all events in the fiscal year that includes the termination date, payable on the date when bonuses for such fiscal year are otherwise paid to the Company’s executives for such fiscal year, plus an additional lump sum payment equal to a pro-rata portion of the target annual bonus that the Participant was eligible to earn for the fiscal year in which the termination date occurs, based on the number of days the Participant was employed during such fiscal year, payable on the next regularly scheduled payroll date following the release effective date but in no event later than sixty (60) days following the termination date;

•

An additional lump sum payment equal to the Participant’s COBRA Multiplier multiplied by the monthly premium for the Participant’s and his or her dependents’ participation in the Company’s group health plans pursuant to COBRA, less the amount of employee contributions that would apply to such participation if the Participant were an active employee, each determined as of the termination date, payable on the next regularly scheduled payroll date following the release effective date but in no event later than sixty (60) days following the termination date; and

•

Full vesting of all of the Participant’s outstanding unvested restricted stock awards (and any other outstanding and unvested equity incentive awards) settled in accordance with the terms of the applicable award agreement governing such awards; provided that, with respect to any performance-based awards, all performance goals or other vesting criteria will be deemed achieved, without proration, at the greater of (A) 100% of target or (B) the maximum level of achievement if actual performance exceeds target as of the Closing, and such awards shall be settled solely in cash and otherwise in accordance with the terms of the applicable award agreement governing such awards.

A Participant’s rights to any severance benefits under the A&R CIC Plan are conditioned upon (i) executing and not revoking a valid separation and general release of claims agreement in a form acceptable to the Company and (ii) the release becoming effective and irrevocable in accordance with its terms within sixty (60) days following the termination date.

Other Compensation Elements

401(k) Plan. We currently maintain a retirement plan intended to provide benefits under Section 401(k) of the Internal Revenue Code of 1986, as amended (the “Code”) under which employees, including our NEOs, are

TABLE OF CONTENTS

allowed to contribute portions of their base compensation to a tax-qualified retirement account under the Insperity 401(k) Savings Plan. We provide matching contributions at a rate of $1.00 for each $1.00 of employee contribution, subject to a cap of the lower of (i) 4% of the employee’s salary and (ii) the applicable contribution limits under the Code. Beginning in 2023, the matching contribution percentage was raised to 6%.

Pension and Nonqualified Deferred Compensation. We have not maintained, and do not currently maintain, a defined benefit pension plan or nonqualified deferred compensation plan.

Perquisites and Other Benefits. We provide limited perquisites to our NEOs, which, to the extent required to be reported under applicable SEC rules and regulations, are reflected in our Summary Compensation Table set forth below.

Anti-Hedging and Pledging Policy. Our Insider Trading Policy generally prohibits our directors, employees and officers from hedging and pledging of Company securities by providing that hedging or monetization transactions, whether direct or indirect, involving the Company’s securities and the pledging of Company securities as collateral are prohibited. Short term exceptions to this prohibition (such as temporary margin loans) may be granted depending on specific facts and circumstances. Any exceptions for our directors and officers must be granted by our Audit Committee and will be periodically communicated to the Board. The policy also prohibits transactions involving Company-based derivative securities.

Clawback Policy

In 2023 the Company adopted a clawback policy that complies with the final rules adopted by the SEC and NYSE. The clawback policy requires us to recoup certain incentive-based compensation erroneously awarded to our current and former executive officers in the event of an accounting restatement. The foregoing description is qualified in its entirety by reference to the final form of the clawback policy as adopted.

Risk Assessment

The Compensation Committee reviewed our employee compensation practices and policies and determined that such policies do not encourage excessive or unnecessary risk-taking, and are not likely to have a material adverse effect on the Company.

Policies and Practices Related to the Grant of Certain Equity Awards in Relation to the Release of Material Non-Public Information

We do not currently grant stock options or option-like equity awards as part of our executive compensation program; therefore, we do not currently have a formal practice or policy with respect to the grant of option or option-like awards. Grants under the LTIP are typically made in connection with the annual compensation cycle and are not granted mid-year when the Company could be in possession of material non-public information. During 2025, we did not time the disclosure of material nonpublic information to affect the value of other types of executive compensation awards granted to any service provider.

(1)	Mr. Zartler does not receive any compensation for his service as Chairman of the Board. The amounts reported in this table for Mr. Zartler only reflect compensation for his service as our Co-Chief Executive Officer.

(2)	Amounts shown in this column for 2024 reflect one-time discretionary bonuses paid to our NEOs for exemplary efforts in transforming the Company’s business during 2024.

(3)

Amounts shown in this column for 2025 reflect the aggregate grant date fair value of the awards of restricted stock awards (“RSAs”) and performance-based restricted stock units (“PSUs”) granted under the LTIP in March 2025 to our named executive officers (excluding Ms. Brock), calculated in accordance with FASB ASC Topic 718, disregarding estimated forfeitures. In addition, the amounts disclosed for 2025 include incremental compensation expense recognized in 2025 related to prior-year PSU awards (granted in 2023 and 2024) that were modified on March 1, 2025 to provide for cash settlement. For more information, please see footnote 4 to the Grants of Plan-Based Awards Table. The Company’s closing stock price on February 28, 2025, the last trading day before the March 1, 2025 grant date, was $34.15 per share. The amounts reported for PSUs reflect the grant-date fair value based on the probable outcome of the applicable performance conditions. The aggregate value of the probable PSUs reflected in this column is as follows for each NEO: Mr. Zartler, $3,903,359, Mr. Ramachandran, $1,127,789, Ms. Durrett, $596,576, Mr. Powell, $511,054, and Mr. Wirtz, $98,511. If the maximum amount, rather than the probable amount, were reported in the table with respect to the PSUs, the aggregate value associated with the PSUs would be as follows for each NEO: Mr. Zartler, $7,806,718, Mr. Ramachandran, $2,255,579, Ms. Durrett, $1,193,152, Mr. Powell, $1,022,108, and Mr. Wirtz, $197,023.

Amounts shown in this column reflect the aggregate grant date fair value of the awards of RSAs and PSUs granted under the LTIP in March 2025 to our named executive officers, calculated in accordance with FASB ASC Topic 718, disregarding estimated forfeitures. The grant date fair value of PSUs is based on the probable outcome of the performance conditions as of the date of grant on March 1, 2025, as determined under ASC Topic 718. The Company’s closing stock price on March 1, 2025 was $34.15. For more information regarding the assumptions underlying the valuation of these equity awards, please see footnote (3) to the Summary Compensation Table above.

The Company’s closing stock price on October 16, 2025, the grant date of such award, was $54.16.

(4)

On March 1, 2025, the Compensation Committee approved that the PSUs that were granted in 2023 and 2024 and that vested on March 1, 2025 to be paid out in cash. This was considered a modification since the awards were being accounted for as equity rather than a liability. The modification date is reflected in this “Grant Date” column. The incremental expense recognized for these awards is in the “Grant Date Fair Value of Stock and Option Awards” column.

•

Full vesting of all of the participant’s outstanding unvested restricted stock awards (and any other outstanding and unvested equity incentive awards); provided that, with respect to any PSUs, all performance goals or other vesting criteria will be deemed achieved at the greater of (i) 100% of the target number of PSUs or (ii) the actual achievement of the applicable performance objectives for such PSUs determined as of the termination date, and all other terms and conditions will be deemed met.

Equity Award Agreements

Under the terms of the equity award agreements, each of our NEOs was eligible to receive the following benefits, subject to compliance with the terms and conditions set forth in the equity award agreements to receive such benefits, in the event of a change in control or certain terminations of employment:

•

Change in control: full vesting of all of the participant’s outstanding unvested restricted stock awards and a number of PSUs shall immediately become vested based on the greater of (i) the number of unvested PSUs necessary for a total number of PSUs under each award equal to the target number of PSUs to have become vested PSUs or (ii) the actual achievement of the applicable performance objectives for such PSUs for each performance period that has not yet ended through the date of the change in control.

(1)	Pursuant to the CIC Plan, NEOs are only eligible for severance benefits if the NEO experiences a termination of employment in connection with a change in control.

Pursuant to the A&R CIC Plan, the cash severance for each NEO would instead be equal to a lump sum payment in an amount equal to the NEO’s applicable multiplier multiplied by the sum of (A) the NEO’s base pay, (B) the greater of (1) the NEO’s target annual bonus for the fiscal year in which the termination date occurs or (2) the NEO’s actual bonus for the fiscal year preceding the fiscal year in which the termination date occurs, and (C) an amount equal to the grant date fair value (determined in accordance with FASB ASC Topic 718) of all equity awards granted to the NEO during the fiscal year in which the termination date occurs (or, if such equity awards have not yet been granted, the grant date fair value of all equity awards granted to the Participant during the fiscal year preceding the fiscal year in which the termination date occurs). As such, the amount disclosable for each NEO under the A&R CIC Plan for “Cash Severance” would be as follows: $37,500,054 for Mr. Zartler, $23,010,000 for Ms. Brock, $10,278,923 for Mr. Ramachandran, $6,010,050 for Ms. Durrett, $5,390,460 for Mr. Powell and $1,725,300 for Mr. Wirtz.

(3)

Pursuant to A&R CIC Plan, the equity acceleration would instead be equal to the full vesting of all of the NEO’s outstanding unvested restricted stock awards (and any other outstanding and unvested equity incentive awards) settled in accordance with the terms of the applicable award agreement governing such awards; provided that, with respect to any performance-based awards, all performance goals or other vesting criteria will be deemed achieved, without proration, at the greater of (A) 100% of target or (B) 200% if actual performance exceeds target as of the Closing. As of December 31, 2025, with respect to performance-based awards, actual performance was equal to 200%. As such, the amount disclosable for each NEO under the A&R CIC Plan for “Equity Acceleration” would be the same as disclosed in the table for the CIC Plan (which is based on actual performance, or 200% as of December 31, 2025).

The Company deducted from and added to the Summary Compensation Table total compensation the following amounts to calculate compensation actually paid in accordance with Item 402(v) of Regulation S-K as disclosed in columns (c), (e) and (g) for our PEOs and Non-PEO NEOs in each respective year. As the Company’s NEOs do not participate in any defined benefit plans, no adjustments were required to amounts reported in the Summary Compensation Table totals related to the value of benefits under such plans. Note that, due to rounding, the sum of the adjustments and the compensation actually paid totals may not precisely equal the amounts disclosed in the table.

Peer Group Total Shareholder Return (“TSR”) is calculated based on the Russell 2000 Index and the Oilfield Service Index. For additional information, see Part II, Item 5. “Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities” of the Company’s Annual Report on Form 10-K for the year ended December 31, 2025.

Relationship between Compensation Actually Paid disclosed in the Pay Versus Performance table, and other table elements

The increase in the Company’s stock price that contributed to the increased compensation actually paid to the PEOs also drove the increase in the Company’s Total Shareholder Return (TSR) in 2025 versus 2024, 2023, 2022 and 2021. The Company's TSR was also greater than the Peer Group TSR for 2025. While the Compensation Committee considers TSR when evaluating total compensation, compensation for the PEOs and non-PEO NEOs is largely driven by cash generation of the business as measured by EBITDA. Given the capital intensity of the business, we do not use net income as a proxy for the overall performance of the Company.

TABLE OF CONTENTS

Other than EBITDA, we did not include any other “Company-Selected Measure” (as described in Item 402(v)) in the Pay Versus Performance table because the most important financial measure used by us to link compensation actually paid to our NEOs to company performance, other than EBITDA, is TSR, which is already required to be disclosed in the table.

Tabular List

The following list represents the most important financial performance measure used by us to link compensation actually paid to our NEOs to company performance, which was only TSR for fiscal year 2024.

TABLE OF CONTENTS

CEO Pay Ratio

As required by Section 953(b) of the Dodd-Frank Wall Street Reform and Consumer Protection Act, and Item 402(u) of Regulation S-K, we are providing the following information about the relationship of the annual total compensation of our employees and the annual total compensation of Mr. Zartler and Ms. Brock, our Co-Chief Executive Officers.

For 2025, our last completed fiscal year:

•	The median of the annual total compensation of all employees of our company (other than Mr. Zartler and Ms. Brock) was $116,403; and

•

The annual total compensation of Mr. Zartler, as reported in the Summary Compensation Table included above, was $13,870,354 while the annual total compensation of Ms. Brock, as reported in the Summary Compensation Table included above, was $7,048,692. Given that Ms. Brock was appointed as Co-Chief Executive Officer on October 16, 2025, her annualized compensation would have been $7,426,000.

•

Based on this information, for 2025, the ratio of the annual total compensation of Mr. Zartler to the median of the annual total compensation of all employees was reasonably estimated to be 119 to 1 while the ratio of the annual total compensation of Ms. Brock to the median of the annual total compensation of all employees was reasonably estimated to be 64 to 1.

To identify the median of the annual total compensation of all our employees, as well as to determine the annual total compensation of our median employee and our Co-Chief Executive Officers, we took the following steps:

•	We determined that, as of December 31, 2025, our employee population consisted of approximately 468 individuals with all of these individuals located in the United States. This population consisted of our full-time, part-time, and temporary employees.

•

We used a consistently applied compensation measure to identify our median employee by comparing the Total Gross Earnings as reflected in our payroll records for 2025, which included, the amount of salary or wages, bonuses, and compensation received from equity award grants and dividend equivalent rights (DERs).

•	We identified our median employee by consistently applying this compensation measure to all of our employees included in our analysis. Since all of our employees are located in the United States, we did not make any cost of living adjustments in identifying the median employee.

•

With respect to the annual total compensation of Mr. Zartler, we used the amount reported in the “Total” column of our 2025 Summary Compensation Table above. With respect to the annual total compensation of Ms. Brock, we used the amount reported in the “Total” column of our 2025 Summary Compensation Table above and annualized such compensation as appropriate.

REPORT OF THE AUDIT COMMITTEE

Management is responsible for preparing the Company’s financial statements and the principal independent public accountants are responsible for auditing those financial statements. The Audit Committee’s role is to provide oversight of management in carrying out management’s responsibility and to appoint, compensate, retain, and oversee the work of the principal independent public accountants.

During 2025, the Audit Committee periodically reviewed and discussed the Company’s financial statements with Company management and BDO USA, the Company’s independent registered public accounting firm, separately, including matters raised by the independent registered public accounting firm pursuant to the applicable requirements of the Public Company Accounting Oversight Board (“PCAOB”) and the SEC. The Audit Committee also discussed with the Company’s management and independent registered public accounting firm the evaluation of the Company’s reporting and internal controls undertaken in connection with certifications by the Company’s Co-Chief Executive Officers and Chief Financial Officer pursuant to the Sarbanes-Oxley Act of 2002 in certain of the Company’s filings with the SEC. The Audit Committee reviewed and discussed the audited financial statements with management and such other matters as it deemed necessary and appropriate. This review included a discussion with management of the quality, not merely the acceptability, of the Company’s accounting principles, the reasonableness of significant estimates and judgments, and the clarity of disclosure in the Company’s financial statements, including the disclosures related to critical accounting estimates. The Audit Committee also discussed with BDO USA the matters required to be discussed by the independent registered public accounting firm with the Audit Committee under the applicable requirements of the PCAOB. The Audit Committee also approved the selection of the Company’s independent registered public accounting firm.

The Company’s independent registered public accounting firm provided the Audit Committee with the written disclosures and the letter concerning its independence, as required by applicable requirements of the PCAOB regarding the independent registered public accounting firm’s communications with the Audit Committee concerning the firm’s independence, and the Audit Committee discussed BDO USA’s independence with them.

Based on the foregoing reviews and discussions, the Audit Committee recommended to the Board that the audited financial statements be included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025, as filed with the SEC on February 27, 2026.

This report of the Audit Committee is not “solicitation material” and shall not be deemed incorporated by reference by any general statement incorporating by reference this Proxy Statement into any filing under the Securities Act or the Exchange Act, except to the extent that the Company specifically incorporates this information by reference, and shall not otherwise be deemed filed under such acts.

RATIFICATION OF APPOINTMENT OF THE COMPANY’S INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM (PROPOSAL NO. 2)

The Audit Committee of the Board has reappointed BDO USA as the Company’s independent registered public accounting firm to audit the financial statements of the Company for 2026, and, as a matter of good corporate governance, is requesting ratification by the shareholders of the appointment of BDO USA to serve as independent auditors for the fiscal year ending December 31, 2026. The Audit Committee and the Board believe that the continued retention of BDO USA as the Company’s independent registered public accounting firm is in the best interests of the Company and its shareholders. If shareholders do not ratify the selection of BDO USA, the Audit Committee will evaluate the shareholder vote when considering the selection of a registered public accounting firm for the audit engagement for the 2027 fiscal year. In addition, if shareholders ratify the selection of BDO USA as independent auditors, the Audit Committee may nevertheless periodically request proposals from the major registered public accounting firms and as a result of such process may select BDO USA or another registered public accounting firm as our independent auditors.

BDO USA has acted as the Company’s independent registered public accounting firm since 2017 and has performed audits of the Company’s financial statements beginning with fiscal year 2015. Representatives of the firm of BDO USA are expected to be present at the Annual Meeting and will have an opportunity to make a statement if they so desire and will be available to respond to appropriate questions.

Vote Required

The ratification of the Company’s independent registered public accounting firm requires the affirmative vote of a majority of the voting power of the outstanding shares of Common Stock present in person or represented by proxy at the Annual Meeting and entitled to vote. Abstentions have the same effect as votes AGAINST the proposal. Brokers have the authority to exercise their discretion with respect to this proposal if they do not receive instructions from the beneficial owner. If you submit a signed proxy card but do not give voting instructions as to how your shares of Common Stock should be voted, your shares will be voted in accordance with the recommendations of our Board stated in this Proxy Statement.

ADVISORY, NON-BINDING VOTE TO APPROVE THE COMPENSATION OF THE COMPANY’S NAMED EXECUTIVE OFFICERS (PROPOSAL NO. 3)

Section 14A(a)(1) of the Exchange Act, which was added to the Exchange Act by Section 951 of the Dodd-Frank Act, affords the stockholders a vote to approve, on a non-binding, advisory basis, the compensation of our Named Executive Officers for the fiscal year ended December 31, 2025 (commonly known as a “say-on-pay vote”). This vote is not intended to address any specific item of compensation and is not a vote on our general compensation policies, compensation of the Board, or our compensation policies as they relate to risk management. Section 14A(a)(2) of the Exchange Act requires us to hold a say-on-pay vote at least once every year (“say-on-frequency”). The next say-on-frequency will take place at the 2029 annual meeting of stockholders.

As described more fully in the “Compensation Discussion & Analysis” section of this Proxy Statement and the accompanying tabular and narrative disclosures, the Company’s compensation policy is designed to attract and retain highly qualified executive officers. The Company’s compensation program seeks to align executive compensation with stockholder value on an annual and long-term basis through a combination of base pay, annual incentives, and certain long-term incentives. Please read the “Compensation Discussion & Analysis” section of this Proxy Statement for additional details on our executive compensation program.

The Board strongly endorses the Company’s executive compensation program and recommends that the stockholders approve on an advisory, non-binding basis, the following resolution:

RESOLVED, that the stockholders approve, on an advisory basis, the compensation of the Company’s Named Executive Officers as described in the proxy statement, including the Compensation Discussion & Analysis section and the tabular and narrative disclosure contained therein.

Vote Required

The approval, on a non-binding basis, of the compensation of our Named Executive Officers requires the affirmative vote of a majority of the voting power of the outstanding shares of Common Stock present in person or represented by proxy at the Annual Meeting and entitled to vote. Abstentions will have the effect of a vote AGAINST the proposal. Brokers do not have the authority to exercise their discretion with respect to this proposal if they do not receive instructions from the beneficial owner. Therefore, it is important that you vote your shares by proxy or in person at the Annual Meeting. If you submit a signed proxy card but do not give voting instructions as to how your shares of Common Stock should be voted, your shares will be voted in accordance with the recommendations of our Board stated in this Proxy Statement.

Recommendation

THE BOARD OF DIRECTORS RECOMMENDS A VOTE “FOR” THE COMPENSATION OF THE COMPANY’S NAMED EXECUTIVE OFFICERS.

OTHER MATTERS

The Board knows of no other matters to be brought before the Annual Meeting. However, if other matters should properly come before the Annual Meeting, it is the intention of each of the persons named in the proxy to vote in accordance with the Board’s recommendations on such matters.
