Dear Shareholders:

You are cordially invited to attend the 2026 Annual Meeting (the “Annual Meeting”) of shareholders (“shareholders”) of WaterBridge Infrastructure LLC (“WaterBridge,” the “Company,” “we,” “us” or “our”) on June 18, 2026, at 4:00 p.m. Central Time. The Annual Meeting will be held in a hybrid format in person at Park House Houston, located at 4411 San Felipe Street, Suite 700, Houston, Texas 77027 and also by means of remote communication conducted virtually via live webcast. You will be able to attend and participate in the Annual Meeting in person or online and vote your common shares in person or electronically. To register to attend the Annual Meeting, please visit http://www.ProxyVote.com and enter your control number included on your Notice of Internet Availability or Proxy card (as defined below). You will not be admitted to the in-person portion of the Annual Meeting if you do not register in advance. Shareholders who have registered and choose to virtually attend the Annual Meeting will be able to join the Annual Meeting at http://www.virtualshareholdermeeting.com/WBI2026.

The matters expected to be acted upon at the Annual Meeting are described in the Proxy Statement (the “Proxy” or “Proxy Statement”). The Annual Meeting materials include the Proxy Statement, our annual report on Form 10-K for the fiscal year ended December 31, 2025 (the “Form 10-K”) and the Proxy card, each of which is enclosed (collectively, the “Proxy Materials”).

Please use this opportunity to vote on the business to come before the Annual Meeting. On or about April 30, 2026, we began mailing a Notice of Internet Availability of Proxy Materials (the “Notice of Internet Availability”), instead of a paper copy of our Proxy Materials. The Notice of Internet Availability contains instructions on how to access the Proxy Materials electronically and how to cast your vote via the internet. The Notice of Internet Availability also contains instructions on how to request a paper copy of our Proxy Materials. All shareholders who have so requested will receive a paper copy of the Proxy Materials by mail. This Proxy Statement and accompanying form of Proxy are dated April 30, 2026, and are expected to be first made available to shareholders on or about April 30, 2026. Only shareholders of record at the close of business on April 23, 2026 may vote at the Annual Meeting and any postponement or adjournment of the Annual Meeting. All shareholders are cordially invited to participate in the Annual Meeting and any postponement or adjournment of the Annual Meeting. However, to ensure your representation at the Annual Meeting, please vote as soon as possible via the internet or telephone, as instructed in the Proxy Materials. Alternatively, you may submit your paper Proxy card by mail. Returning the paper Proxy card or voting electronically does NOT deprive you of your right to participate in the Annual Meeting and to vote your common shares for the matters acted upon at the Annual Meeting.

Your vote is important. Whether or not you expect to attend and participate in the Annual Meeting, please submit your Proxy electronically via the internet or by telephone, or complete, sign and date the paper Proxy card and return it in the pre-paid envelope provided.

Sincerely,

 

David N. Capobianco

Chairman of the Board

IMPORTANT NOTICE REGARDING THE AVAILABILITY OF PROXY MATERIALS FOR THE

ANNUAL MEETING OF SHAREHOLDERS TO BE HELD ON JUNE 18, 2026: Our Proxy Materials are

available free of charge at http://www.ProxyVote.com.

In-person admission to the Annual Meeting will be on a first-come, first-served basis. For in-person admission to the Annual Meeting, you must (i) register in advance at http://www.ProxyVote.com with your 16 digit control number and select “Attend the Meeting” and (ii) present your proof of share ownership (such as your Proxy card or voting instruction statements from a broker or bank) and government-issued photo identification (such as a driver’s license or passport). You will not be admitted to the Annual Meeting if you have not registered in advance. Please see “How do I pre-register for the Annual Meeting?” below. If you are representing an entity that is a shareholder, you must also present documentation showing your authority to attend and act on behalf of the entity (such as a power of attorney, written proxy to vote or letter of authorization on the entity’s letterhead). We reserve the right to restrict admission to the meeting or limit the number of representatives for any entity that may be admitted to the meeting for security or safety reasons at our sole discretion.

If you do not pre-register for the Annual Meeting, you will not be admitted to the Annual Meeting. Attendees who disrupt or impede the meeting or breach the rules of conduct may be removed from the Annual Meeting. The use of cameras, sound recording equipment, communication devices or other similar equipment at the Annual Meeting is prohibited.

The Annual Meeting webcast will begin promptly at 4:00 p.m. Central Time. If you plan on attending virtually, we encourage you to access the Annual Meeting 15 minutes prior to the start time.

If your common shares are registered directly in your name with our transfer agent, Continental Stock Transfer & Trust Company, you are considered the shareholder of record with respect to those common shares, and these Proxy Materials were sent directly to you.

If your common shares are held in an account at a brokerage firm, bank, broker-dealer, or other similar organization, then you are the “beneficial owner” of common shares held in “street name,” and these Proxy Materials were forwarded to you by that organization.

You may vote by ballot during the Annual Meeting, by virtual means during the Annual Meeting, or by internet, mail or telephone prior to the Annual Meeting as described in your Proxy card.

Your vote is important. Regardless of whether you plan to attend the Annual Meeting, we urge you to vote by Proxy to ensure that your vote is counted.

The procedures for voting are as follows:

If you are a shareholder of record, you may vote as follows:

You must register to attend and vote and may do so by following the instructions in your Proxy materials. Submitting your Proxy, whether by telephone, through the internet or by mail will not affect your right to vote by virtual means or in person at the Annual Meeting should you decide to attend and participate in the Annual Meeting.

If you hold your common shares in street name, please refer to the voting instructions provided by your bank, broker or other nominee to vote your shares. Beneficial owners voting by telephone or internet may submit votes until the polls are closed at the Annual Meeting.

If you are the beneficial owner of shares held in street name, you should refer to the voting instructions provided by your brokerage firm, bank or other holder of record. If you want to vote in person at the Annual Meeting, you must present this legal proxy at the entrance to the Annual Meeting.

The telephone and internet voting procedures are designed to authenticate shareholders’ identities, to allow shareholders to give their voting instructions and to confirm that shareholders’ instructions have been recorded properly.

business at, the Annual Meeting. This presence is called a quorum. Your common shares are counted as present at the Annual Meeting if you are present and vote in person or virtually at the Annual Meeting or if you have properly submitted a Proxy. On the Record Date, there were 47,016,059 Class A shares outstanding and entitled to vote and 76,440,150 Class B shares outstanding and entitled to vote. Thus, the holders of at least 61,728,105 common shares must be present in person or virtually or represented by Proxy at the Annual Meeting to have a quorum. To the extent WBR Holdings LLC (“WBR Holdings”), NDB Holdings LLC and Desert Environmental Holdings LLC (collectively, the “Five Point Members”), with the ability to direct the voting of a majority of our common shares, are all present in person or virtually or represented by Proxy at the Annual Meeting, we will have a quorum for the purpose of conducting business at the Annual Meeting.

A broker non-vote occurs when the beneficial owner of common shares fails to provide the bank, broker or other nominee that holds the common shares with specific instructions on how to vote on any “non-routine” matters brought to a vote at the shareholders meeting. In this situation, the bank, broker or other nominee will not vote on the “non-routine” matters. Broker non-votes are counted for purposes of determining whether a quorum is present.

For Proposal No. 1, votes that are withheld from a director’s election and broker non-votes are not treated as votes cast and, therefore, will have no effect on the outcome of the proposal. For Proposal No. 2, abstentions are not treated as votes cast and, therefore, will have no effect on the outcome of the proposal. Since Proposal No. 2 is a “routine” proposal (as discussed below), we do not expect any broker non-votes with respect to this proposal. For Proposal No. 3, abstentions and broker non-votes are not treated as votes cast “for” or “against” the proposal and, therefore, will have no effect on the outcome of the proposal. For Proposal No. 4, abstentions and broker non-votes are not treated as votes cast “for” any frequency period and, therefore, will have no effect on the outcome of the proposal.

Note that if you are a beneficial owner, banks, brokers and other nominees will be entitled to vote your common shares on “routine” matters without instructions from you. The only proposal that would be considered “routine” in such event is the proposal for the ratification of the appointment of Deloitte & Touche LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2026 (Proposal No. 2). A bank, broker or other nominee will not be entitled to vote your shares on any “non-routine” matters, absent instructions from you. This year, the “non-routine” matters relate to the election of directors (Proposal No. 1), the approval, on an advisory, non-binding basis, of Named Executive Officers’ compensation (Proposal No. 3), and the approval, on an advisory, non-binding basis, of the frequency of future advisory votes on Named Executive Officers’ compensation (Proposal No. 4). Accordingly, we encourage you to provide voting instructions to your bank, broker or other nominee regardless of whether you plan to attend the Annual Meeting.

You should vote in accordance with all of the Proxy cards and voting instruction cards you receive relating to our Annual Meeting to ensure that all of your common shares are voted and counted.

If you are the shareholder of record, you may change your vote by:

Attendance alone at the Annual Meeting (whether in person or virtually) will not cause your previously granted Proxy to be revoked unless you specifically vote during the Annual Meeting.

Please note, however, that if your common shares are held of record by a bank, broker or other nominee and you wish to revoke a Proxy, you must contact such bank, broker or other nominee to revoke any prior voting instructions.

Please note that we will only address questions that are germane to the matters being voted on at our Annual Meeting, as time permits. Additional information regarding the ability of shareholders to ask questions during the Annual Meeting, rules of conduct at the Annual Meeting, and other materials for the Annual Meeting will be available online and are accessible by following the instructions on your Proxy card.

If you choose to receive future Proxy Materials by email, you will receive an email next year with instructions containing a link to those materials and a link to the Proxy voting site. Your election to receive Proxy Materials by email will remain in effect until you terminate it.

The LLC Agreement provides that shareholders, other than those party to the Shareholders’ Agreement (as defined below), may present proposals for inclusion in our proxy statement, including nominations of director nominees, by submitting their proposals in writing to our secretary at 5555 San Felipe Street, Suite 1200, Houston, Texas 77056. Shareholder proposals must comply with the requirements of our LLC Agreement and Rule 14a-8 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and related SEC regulations under Rule 14a-8 regarding the inclusion of shareholder proposals in Company-sponsored proxy materials. To be eligible for inclusion in the proxy statement for our 2027 Annual Meeting, shareholder proposals must be received by our secretary no later than December 31, 2026.

Our LLC Agreement provides that shareholders may present proposals, including nominations of director nominees, to be considered at an annual meeting by providing timely notice.

To be timely for our 2027 Annual Meeting, our Secretary must receive the written notice:

If we hold our 2027 Annual Meeting more than 30 days before or after June 18, 2027 (the anniversary of the immediately preceding annual meeting), then notice of a shareholder proposal must be received by the Secretary of the Company not earlier than the close of business on the 120^th day and not later than the close of business on the later of the 90^th day prior to our 2027 Annual Meeting or, if the first public announcement of the date of such annual meeting is less than 90 days prior to the date of our 2027 Annual Meeting, the 10^th day following the day on which public announcement of the date of our 2027 Annual Meeting is first made by the Company.

A shareholder’s notice to our Secretary must set forth as to each matter the shareholder proposes to bring before the annual meeting the information required by our LLC Agreement. If a shareholder who has notified the Company of his or her intention to present a proposal at an annual meeting does not appear to present such proposal at such meeting, and a qualified representative of such shareholder does not appear to present such proposal at such meeting, the proposal shall be disregarded and the proposed business shall not be transacted, notwithstanding that Proxies in favor thereof may have been received by the Company. A qualified representative of a shareholder is a duly authorized officer, manager or partner of such shareholder or must be authorized by a writing executed by such shareholder or an electronic transmission delivered by such shareholder to act for such shareholder as proxy at such meeting.

Any shareholder who intends to solicit proxies in support of any director nominees must comply with the content requirements of SEC Rule 14a-19 (the SEC’s universal proxy rule) at the time it complies with the earlier deadlines in the Company’s advance notice provisions of our LLC Agreement. Thus, if a shareholder intends to solicit proxies in support of any director nominees submitted under the advance notice provisions of our LLC Agreement for the Company’s 2027 Annual Meeting, then such shareholder must also provide proper written notice that sets forth all the information required by SEC Rule 14a-19 to the Secretary of the Company at the principal office of the Company not less than 90 calendar days (January 30, 2027) nor more than 120 calendar days (December 31, 2026) prior to the anniversary date of the public announcement for the prior year’s annual meeting.

We have a strong commitment to good corporate governance practices. These practices provide an important framework within which our Board, its committees and our management can pursue our strategic objectives in order to promote the interests of the Company and our shareholders.

Our Board does not have a policy regarding separation of the roles of chief executive officer and chairman of the Board. Our Board believes it is in our best interests to make that determination from time to time based on circumstances.

Jason Long serves as our Chief Executive Officer (our principal executive officer) and David N. Capobianco serves as Chairman of the Board. Our Board believes that this leadership structure, separating the Chairman and Chief Executive Officer roles, is appropriate for the Company at this time, since it allows Mr. Long to focus on the day-to-day operations of the business and operational leadership. At the same time, Mr. Capobianco can focus on the strategic direction of the Company and leadership of our Board, including calling and presiding over meetings of our Board and serving as a liaison and supplemental channel of communication between our Board and the Chief Executive Officer.

Consistent with our governance policies and procedures, our Board is responsible for assessing the major risks facing us and the options for their mitigation. This responsibility is largely satisfied by our Audit Committee, which is responsible for reviewing and discussing with management and our independent auditor any significant risks or exposures, including our financial risk exposures, and the Company’s policies and processes with respect to risk assessment and risk management and assessing the steps management has taken to monitor and control such risks.

Our Board has adopted Corporate Governance Guidelines in accordance with the corporate governance rules of the New York Stock Exchange (“NYSE”) and NYSE Texas, Inc. (“NYSE Texas”), taking into account the Company’s status as a “controlled company,” meaning a company of which more than 50% of the voting power for the election of directors is held by an individual, group or another company, under the NYSE and NYSE Texas rules that exempt the Company from certain corporate governance requirements, which set forth expectations for directors, director independence and qualification standards, Board committee structure and functions and other policies for the governance of our Company. Our Corporate Governance Guidelines are available without charge on the Investor Relations section of our website, which is located at https://wbinfra.com/investor-relations/investor-overview by clicking on “Governance Documents” under the “Governance” section of our website. Our Corporate Governance Guidelines are subject to modification from time to time by our Board as it may deem appropriate and in the best interests of the Company and its shareholders, or as required by applicable laws and regulations.

Our Board consists of 13 directors, four of whom satisfy the independence requirements of the Exchange Act and the NYSE and NYSE Texas rules. Our Board has determined that each of Greg Daily, James Crane, Janet Carrig and Valerie P. Chase are independent within the meaning of the NYSE and NYSE Texas rules and Rule 10A-3 of the Exchange Act.

Our independent directors meet regularly in executive sessions not attended by management, in conjunction with each regular Board meeting and as they otherwise deem appropriate, including being called by an independent director at his or her discretion or at the request of the Board. Following each executive session, the independent directors report the results of the discussions to the full Board, as appropriate.

In evaluating director candidates we assess whether a candidate possesses the integrity, judgment, knowledge, experience, skills and expertise that are likely to enhance our Board’s ability to manage and direct our affairs and business, including, when applicable, to enhance the ability of a committee of the Board to fulfill its duties. In particular, we will assess candidates that:

We consider a number of additional qualifications in evaluating a person’s candidacy for membership on the Board. We may require certain skills or attributes, such as financial or accounting experience, to meet specific Board needs that arise from time to time and will also consider the overall experience and makeup of the Board’s members to obtain a broad and diverse mix of Board members.

Our LLC Agreement provides that our Board shall consist of such number of directors as shall be determined from time to time by our Board but shall not consist of less than nine directors. We have a single class of directors, and directors are subject to re-election on an annual basis at each annual meeting. Our Shareholders’ Agreement provides that, subject to compliance with applicable law and NYSE and NYSE Texas rules, for so long as the Five Point Members and certain affiliates beneficially own at least 40% of our outstanding common shares, the Five Point Members shall be entitled to designate a number of directors equal to a majority of the Board, plus one director; and for so long as the Five Point Members and such affiliates beneficially own at least 30%, 20% and 10% of our outstanding common shares, the Five Point Members shall be entitled to designate at least three directors, two directors and one director, respectively; and for so long as Devon WB Holdco L.L.C. (“Devon Holdco”) and its affiliates beneficially own at least 10% of our outstanding common shares, Devon Holdco shall be entitled to designate one director to the Board. After the Five Point Members, Devon Holdco and their affiliates no longer beneficially own or control the voting of more than 40% of the outstanding common shares (the “Trigger Event”), our Board will be divided into three classes that are as nearly equal in number as is reasonably possible and each director will be assigned to one of the three classes; provided that the Five Point Members shall have the collective right to designate the initial class assigned to each director immediately following the occurrence of the Trigger Event. After the Trigger Event, at each annual meeting, a class of directors will be elected for a three-year term to succeed the directors of the same class whose terms are then expiring. The initial terms of the Class I, Class II and Class III directors will expire at the first, second and third, respectively, annual meeting following the Trigger Event.

Our LLC Agreement does not provide for cumulative voting in the election of directors, which means that the holders of a majority of our issued and outstanding common shares can elect all of the directors standing for election, and the holders of the remaining common shares are not able to elect any directors. The Five Point Members’ beneficial ownership of greater than 50% of our common shares means the Five Point Members, as a group, are able to control matters requiring shareholder approval, including the election of directors. In addition, the Five Point Members maintain certain director designation rights.

Our directors hold office until the earlier of their death, resignation, retirement, disqualification or removal or until their successors have been duly elected and qualified. Certain provisions of our LLC Agreement are subject to the terms of the Shareholders’ Agreement, which is described below under “Nominations Process and Director Qualifications—Nomination to our Board.”

Because the Five Point Members, as a group, control more than 50% of our voting power for the election of directors, we are a controlled company under the Sarbanes-Oxley Act of 2002 (“Sarbanes-Oxley Act”) and the NYSE and NYSE Texas rules. In addition, should the Five Point Members control less than 50% of our voting power, so long as Devon Holdco holds the requisite number of shares along with the Five Point Members to control more than 50% of our voting power, then we will continue to remain a controlled company. A controlled company is not required to have a majority of independent directors on its board of directors or to form an independent compensation or nominating and corporate governance committee. As a controlled company, we remain subject to the Sarbanes-Oxley Act and the rules of the NYSE and NYSE Texas that require us to have an audit committee composed entirely of independent directors.

If at any time we cease to be a controlled company, we intend to take all action necessary to comply with the Sarbanes-Oxley Act and the NYSE and NYSE Texas rules, including by appointing a majority of independent directors to our Board and establishing a compensation committee and a nominating and corporate governance committee, each composed entirely of independent directors, subject to a permitted “phase-in” period.

We are required to have an audit committee of at least three members, and all of its members are required to meet the independence and experience standards established by each of the Exchange Act and the NYSE and NYSE Texas rules, subject to certain transitional relief described above. We have established an audit committee (the “Audit Committee”) compliant with each of the SEC and the NYSE and NYSE Texas rules. Our Audit Committee consists of Greg Daily, Janet Carrig and Valerie P. Chase, each of whom is independent under the applicable rules of each of the SEC and the NYSE and NYSE Texas. Our Board has determined that Valerie P. Chase is an audit committee financial expert as defined by the SEC. Our Audit Committee operates under a written charter, which satisfies applicable SEC rules and NYSE and NYSE Texas rules and is available on our website at https://wbinfra.com/investor-relations/investor-overview in “Governance Documents” under the “Governance” section of our website.

The Audit Committee oversees, reviews, acts on and reports on various auditing and accounting matters, including the selection of our independent accountants, the scope of our annual audits, fees to be paid to the independent accountants, the performance of our independent accountants and our accounting practices. In addition, the Audit Committee oversees our compliance programs relating to legal and regulatory requirements and company policies and controls. The Audit Committee has the sole authority to (1) retain and terminate our independent registered public accounting firm, (2) approve all auditing services and related fees and the terms thereof performed by our independent registered public accounting firm, and (3) pre-approve any non-audit services and tax services to be rendered by our independent registered public accounting firm. The Audit Committee is also responsible for confirming the independence and objectivity of our independent registered public accounting firm. Our independent registered public accounting firm has been given unrestricted access to the Audit Committee and our management.

In accordance with the terms of our LLC Agreement, our Board may from time to time refer specific matters that may involve conflicts of interest to a conflicts committee. The members of any such conflicts committee must be comprised entirely of directors who meet the then current independence standards established by each of the SEC and the NYSE and NYSE Texas and must be determined by the Board to be independent with respect to any transaction, activity, arrangement or circumstance to be evaluated by such Conflicts Committee.

Because we are a “controlled company” within the meaning of the NYSE and NYSE Texas rules, we are not required to have, and do not currently have, a compensation committee.

If and when we are no longer a “controlled company” within the meaning of each of the NYSE and NYSE Texas rules, we will be required to establish a compensation committee compliant with each of the SEC and the NYSE and NYSE Texas rules. We anticipate that such a compensation committee would consist of three directors who will be “independent” under the applicable rules of each of the SEC and the NYSE and NYSE Texas. This committee would establish salaries, incentives and other forms of compensation for officers and other employees. Any compensation committee would also administer our incentive compensation and benefit plans. Upon formation of any compensation committee, we would expect to adopt a compensation committee charter defining the committee’s primary duties in a manner consistent with the rules of each of the SEC and the NYSE and NYSE Texas.

Because we are a “controlled company” within the meaning of the NYSE and NYSE Texas rules, we are not required to have, and do not currently have, a nominating and corporate governance committee.

If and when we are no longer a “controlled company” within the meaning of each of the NYSE and NYSE Texas rules, we will be required to establish a nominating and corporate governance committee compliant with each of the SEC and the NYSE and NYSE Texas rules. We anticipate that such a nominating and corporate governance

committee would consist of three directors who will be “independent” under the applicable rules of the SEC and the NYSE and NYSE Texas. This committee would identify, evaluate and recommend qualified nominees to serve on our Board, develop and oversee our internal corporate governance processes and maintain a management succession plan. Upon formation of any nominating and corporate governance committee, we would expect to adopt a nominating and corporate governance committee charter defining the committee’s primary duties in a manner consistent with the rules of each of the SEC and the NYSE and NYSE Texas.

The Company has an insider trading policy (“Insider Trading Policy”) governing transactions in 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 Insider Trading Policy was filed as Exhibit 19.1 to its Annual Report on Form 10-K for the year ended December 31, 2025.

Our Board and its committees meet regularly throughout the year and also may hold special meetings and act by written consent from time to time. From the date of the IPO (as defined below) through December 31, 2025, our Board met once and our Audit Committee met once.

From the date of the IPO through December 31, 2025, each member of our Board attended at least 75% of the total number of meetings of the Board of Directors and of the meetings held by all Board committees on which such director served.

Our policy is to invite and encourage each member of our Board to be present at our annual meetings of shareholders. The Annual Meeting will be our first annual meeting following our initial public offering in September 2025 (“IPO”).

We believe that regular shareholder and stakeholder engagement is essential to our success as a company. Shareholders and other interested parties who wish to communicate with our Board as a group, our independent directors as a group, a committee of our Board or a specific member of our Board (including our Chairman of the Board) may do so by letters addressed to the attention of our General Counsel.

All communications are reviewed by the General Counsel and provided to the members of our Board, our independent directors as a group, a committee of our Board or a specific member of our Board (including our Chairman of the Board) as appropriate. Unsolicited items, sales materials, abusive, threatening or otherwise inappropriate materials and other routine items and items unrelated to the duties and responsibilities of our Board will not be provided to directors. The mailing envelope must contain a clear notation indicating that the enclosed letter is an “WBI Shareholder—Board Communication” or “WBI Shareholder—Director Communication.” All such letters must identify the author as a shareholder and clearly state whether the intended recipients are all members of our Board, our independent directors as a group, a committee of our Board or a specific member of our Board (including our Chairman of the Board).

The address for these communications is:

WaterBridge Infrastructure LLC

Our Board has adopted a code of business conduct and ethics applicable to our employees, directors and officers in accordance with applicable U.S. federal securities laws and the corporate governance rules of the NYSE and NYSE Texas, which is available on our website at https://wbinfra.com/investor-relations/investor-overview by clicking on “Governance Documents” under the “Governance” section of our website. Any waiver of our code of business conduct and ethics may be made only by our Board and will be promptly disclosed as required by applicable U.S. federal securities laws and the corporate governance rules of the NYSE and NYSE Texas.

Given our status as a controlled company, our Board does not have a nominating and corporate governance committee. Instead, candidates for nomination to our Board are designated by our principal shareholders and selected by our Board in accordance with our LLC Agreement, and are subject to the provisions of the Shareholders’ Agreement. See “Certain Relationships and Related Party Transactions—Shareholders’ Agreement” for additional information about the Five Point Members’ and Devon Holdco’s ability to designate certain members of our Board.

Valerie P. Chase was recommended for service on our Board by the Chairman of our Board.

The identification, evaluation and selection of qualified directors is a complex and subjective process that requires consideration of many intangible factors and will be significantly influenced by the particular needs of our Board from time to time. The guidelines for selecting director nominees are set forth in “Corporate Governance—Composition of Our Board; Director Independence.”

The brief biographical description of each director set forth in “Proposal No. 1: Election of Directors” below includes the primary individual experience, qualifications, attributes and skills of each of our directors that led to the conclusion that each director should serve as a member of our Board at this time.

Our Board currently consists of 13 directors. All of our current directors will stand for re-election at the Annual Meeting. Our Board proposes that each of the nominees named below be elected as a director for a one-year term expiring at our 2027 Annual Meeting, or until such director’s successor is duly elected and qualified or until such director’s earlier death, resignation, disqualification or removal.

Unless otherwise instructed, shares represented by proxies will be voted “FOR” the election of each of the nominees named below. If any nominee for any reason is unable to serve or for good cause will not serve, the proxies may be voted for such substitute nominee as the proxy holder might determine. Each nominee has consented to being named in this Proxy Statement and to serve if elected. Proxies may not be voted for more than 13 directors. Shareholders may not cumulate votes for the election of directors.

The nominees and their ages, occupations and lengths of service on our Board as of the date of the Proxy are provided in the table below and in the additional biographical descriptions set forth in the text below the table.

Jason Long—Chief Executive Officer; Director. Mr. Long has served as our Chief Executive Officer since April 2025 and our director since September 2025. Mr. Long previously served as President and Chief Executive Officer of WaterBridge’s predecessor entities from January 2024 to March 2025, Co-Chief Executive Officer and Chief Operating Officer of WaterBridge’s predecessor entities from May 2020 to December 2023, and as Co-President and Chief Operating Officer of WaterBridge’s predecessor entities from August 2017 to May 2020. Mr. Long also currently serves as President and Chief Executive Officer of LandBridge Company, LLC (NYSE: LB) (NYSE Texas: LB) (“LandBridge”) and has served in such role since January 2024. He has also served as a director of LandBridge since July 2024. Mr. Long previously served as Co-Chief Executive Officer and Chief Operating Officer of LandBridge and its predecessor from September 2021 until December 2023. Prior to joining WaterBridge’s predecessor entities, Mr. Long founded and served as President of EnWater Solutions, LLC (“EnWater”) and Pelagic Water Systems, LLC (“Pelagic”), each a produced water gathering and disposal company in the Delaware Basin, from January 2014 to July 2017. Mr. Long graduated from Texas Christian University with a Bachelor of Science. A native of West Texas, Mr. Long is an oil and natural gas entrepreneur with more than 20 years of experience founding and operating businesses.

We believe that Mr. Long’s substantial experience founding and operating businesses, particularly in the industry in which we operate, makes him well qualified to serve as a member of our Board.

David N. Capobianco—Director. Mr. Capobianco has served as our director since September 2025. He has also served as the Chief Executive Officer and Managing Partner of Five Point since its founding in 2012. Prior to founding Five Point, Mr. Capobianco was a founder and co-head of the private equity group at Vulcan Capital. Mr. Capobianco also currently serves as Chairman of the board of directors of LandBridge, PowerBridge LLC, Twin Eagle Resource Management LLC and Deep Blue Midland Basin LLC and as a member of the board of

directors of San Mateo Midstream, LLC (“San Mateo Midstream”). He previously served as the Chairman of the board of directors of Northwind Midstream Holdings LLC, a Five Point portfolio company sold to MPLX LP (NYSE: MPLX) in September 2025, and Vulcan Energy Corporation (formerly Plains Resources), a member of the board of directors and chairman of the compensation committee of Plains All American Pipeline, L.P. (NYSE: PAA), a member of the board of directors of PAA/Vulcan Gas Storage (formerly Energy Center Investments), and Chairman of the board of directors of Vulcan Resources (formerly Calumet Florida). Before joining Vulcan, Mr. Capobianco served as senior member of the investment team at Greenhill Capital Partners, a member of the investment team of Harvest Partners and a member of the Energy Corporate Finance Group at Salomon Brothers.

OUR BOARD RECOMMENDS A VOTE “FOR” ALL NOMINEES FOR

ELECTION AS DIRECTORS FOR PROPOSAL NO. 1.

The Audit Committee has appointed Deloitte & Touche LLP (“Deloitte”), an independent registered public accounting firm, to audit our consolidated financial statements for the fiscal year ending December 31, 2026, and our Board is asking shareholders to ratify that selection. Although current law, rules, and regulations, as well as the charter of the Audit Committee, require the Audit Committee to engage, retain, and supervise the Company’s independent registered public accounting firm, our Board considers the selection of the independent registered public accounting firm to be an important matter of shareholder concern and is submitting the selection of Deloitte for ratification by shareholders as a matter of good corporate practice.

Deloitte has continuously served as our independent registered public accounting firm since the consummation of our IPO and as our predecessors’ independent auditor since 2020. A representative of Deloitte is expected to be present during the Annual Meeting and, if present, Deloitte will have an opportunity to make a statement if such representative desires to do so and is expected to be available to respond to appropriate questions from the shareholders during the Annual Meeting.

The following is a summary of the fees billed to us (or our predecessor) by Deloitte for professional services rendered for the fiscal years ending on December 31, 2025 and December 31, 2024.

Our Audit Committee Pre-Approval Policy provides for the pre-approval of certain audit and permissible non-audit services provided by our independent registered public accounting firm, the scope of services provided by our independent registered public accounting firm and the fees for the services to be performed. These services may include audit services, audit-related services, tax services and other services. Pre-approval is detailed as to the particular service or category of services and is generally subject to a specific budget. Our independent registered public accounting firm and management are required to periodically report to the Audit Committee regarding the nature of services provided by our independent registered public accounting firm in accordance with the Pre-Approval Policy, and the fees for the services performed to date.

OUR BOARD RECOMMENDS A VOTE “FOR” APPROVAL OF PROPOSAL NO. 2.

Our policies are conceived with the intention of attracting and retaining highly qualified individuals capable of contributing to the creation of value for our shareholders. Our compensation program for 2025 was designed to be competitive with market practices and to align the interests of our Named Executive Officers with those of WaterBridge and its shareholders.

Shareholders are urged to read the Compensation Discussion and Analysis section of this Proxy Statement, which discusses how our compensation design and practices reflect our compensation philosophy for calendar year 2025. The Board believes that our compensation practices for 2025 were effective in implementing our guiding principles.

Pursuant to Section 14A of the Exchange Act, we are submitting this annual proposal to our shareholders for an advisory vote to approve the compensation of our Named Executive Officers. This proposal, commonly known as a “say-on-pay” proposal, gives shareholders the opportunity to express their views on the compensation of our Named Executive Officers for 2025. This vote is not intended to address any specific item of compensation, but rather the overall compensation of our Named Executive Officers for 2025 and the principles, policies and practices described in this Proxy Statement.

Accordingly, the following resolution is submitted for shareholder vote at the Annual Meeting:

“RESOLVED, that the shareholders of WaterBridge approve, on an advisory basis, the compensation of its named executive officers during 2025 as disclosed in the proxy statement for the Annual Meeting pursuant to the compensation disclosure rules of the Securities and Exchange Commission, including the Compensation Discussion and Analysis, the Summary Compensation Table and other related tables and disclosures.”

As this is an advisory vote, the result is not likely to affect previously granted compensation. The Board will consider the outcome of the vote when evaluating our compensation practices going forward.

OUR BOARD RECOMMENDS A VOTE “FOR” APPROVAL OF PROPOSAL NO. 3.

As described in Proposal No. 3 above, our shareholders are being provided the opportunity to cast an advisory vote on our executive compensation program. The advisory vote on executive compensation described in Proposal No. 3 above is referred to as a “say-on-pay” vote.

Pursuant to Section 14A of the Exchange Act, this Proposal No. 4 affords shareholders the opportunity to cast an advisory vote on how often we should include a say-on-pay vote in our proxy materials for future annual shareholder meetings (or a special shareholder meeting for which we must include executive compensation information in the Proxy Statement for that meeting). We believe that say-on-pay votes should be conducted every year so that shareholders may provide us with direct and timely input on our executive compensation program. Please note that this vote is advisory and not binding on WaterBridge or the Board in any way. The Board will take into account the outcome of the vote, however, when considering the frequency of future advisory votes on executive compensation. The Board may decide now or in the future that it is in the best interests of our shareholders and our company to hold an advisory vote on executive compensation on a different frequency than the frequency receiving the most votes cast by our shareholders.

Under this Proposal No. 4, shareholders may vote to have the say-on-pay vote every one year, every two years, every three years or abstain from voting in response to the resolution set forth below.

“RESOLVED, that the shareholders determine, on an advisory basis, whether the preferred frequency of an advisory vote on the executive compensation of WaterBridge’s named executive officers as set forth in the company’s proxy statement should be every year, every two years, or every three years.”

The Proxy card provides shareholders with the opportunity to choose among four options (holding the vote every one, two or three years, or abstaining) and, therefore, shareholders will not be voting to approve or disapprove the recommendation of the Board.

OUR BOARD RECOMMENDS A VOTE FOR THE OPTION OF “ONE YEAR”

AS THE PREFERRED FREQUENCY OF ADVISORY VOTES ON

EXECUTIVE COMPENSATION FOR PROPOSAL NO. 4.

The information contained in the following report of our Audit Committee is not considered to be “soliciting material,” “filed” with or incorporated by reference in any past or future filing by us under the Exchange Act or the Securities Act of 1933, as amended (the “Securities Act”), unless and only to the extent that we specifically incorporate it by reference.

Management is responsible for the Company’s financial reporting process, including the responsibility to prepare our consolidated financial statements in accordance with generally accepted accounting principles in the United States (“GAAP”). The Company’s independent registered public accounting firm is responsible for auditing those financial statements and expressing an opinion as to their conformity with GAAP. The Audit Committee’s responsibility is to oversee and review these processes. The Audit Committee is not, however, engaged in the practice of accounting or auditing and does not provide any expert or other special assurance as to such financial statements concerning compliance with laws, regulations or GAAP, or as to the independence of the independent registered public accounting firm. The Audit Committee relies, without independent verification, on the information provided to it and on the representations made by management and the independent registered public accounting firm. The Audit Committee’s responsibilities are described in its charter. A copy of the Audit Committee’s charter is available on our website at https://wbinfra.com/investor-relations/investor-overview by clicking on “Governance Documents” under the “Governance” section of our website.

In connection with the evaluation, appointment and retention of the independent registered public accounting firm, at least annually the Audit Committee reviews and evaluates the independence and quality control procedures of the independent registered public accounting firm and the experience and qualifications of its senior personnel providing audit services to the Company. In connection with this assessment, the Audit Committee shall ensure the receipt of and review formal written statements from the independent auditor delineating all relationships between the auditor and the Company, consistent with applicable requirements of the Public Company Accounting Oversight Board (“PCAOB”) regarding the independent auditor’s communications with the Audit Committee concerning independence. The Audit Committee shall engage in an active dialogue with the independent auditor concerning any disclosed relationships or services that may impact the objectivity and independence of the auditor and take, or recommend that the Board take, appropriate action to oversee and ensure the independence of the auditor. Based on this overall evaluation, the Audit Committee retained Deloitte as our independent registered public accounting firm for 2025.

In fulfilling its oversight role for the year ended December 31, 2025, our Audit Committee has reviewed and discussed our audited consolidated financial statements for the fiscal year ended December 31, 2025 with management and Deloitte. Our Audit Committee has also discussed with Deloitte the matters required to be discussed by the applicable requirements of the PCAOB and the SEC.

Our Audit Committee has received and reviewed the written disclosures and the letter from Deloitte required by applicable requirements of the PCAOB regarding the independent registered public accounting firm’s communications with our Audit Committee concerning independence and has discussed with Deloitte its independence.

Based on the review and discussions referred to above, and subject to the limitations on the Audit Committee’s role and responsibilities referred to above and in its charter, our Audit Committee recommended to our Board that the audited consolidated financial statements be included in our annual report on Form 10-K for the fiscal year ended December 31, 2025 filed with the SEC.

Mr. Williams received a Bachelor of Science in Accounting from the University of Houston, Clear Lake, in 2004.

With respect to the year ended December 31, 2025, our “Named Executive Officers” or “NEOs” were as follows:

WaterBridge’s 2025 executive compensation program was designed to attract, motivate and retain talented individuals who are committed to achieving our long-term strategic objectives and creating shareholder value. Since our IPO was completed in September 2025, our 2025 compensation program included private company compensation. Our 2025 compensation program consisted of a base salary, a short-term incentive plan and long-term share-based compensation as discussed below. Our compensation structure is designed to align the incentives of our executives with our shareholders’ interests.

Because we are a “controlled company” within the meaning of the NYSE and NYSE Texas rules, we are not required to, and do not currently expect to, have a compensation committee in the present or foreseeable future. The Chairman of our Board makes decisions regarding executive compensation based on the information presented to him by our management team that is derived from executive compensation analytics provided to management by an independent compensation consultant. Our Chief Executive Officer does not recuse himself from votes or Board discussions relating to this compensation.

During 2025, in anticipation of the IPO, management engaged an independent compensation consultant to assist with compiling executive compensation data based on certain selected peer groups (defined below). Such compensation information was then presented to the Chairman of our Board to facilitate discussion surrounding executive compensation structures and programs in connection with determining post-IPO base salaries, target bonus amounts and Long-Term Incentive Program (“LTIP”) grants.

During 2025, management engaged Pay Governance LLC (“Pay Governance”) as its independent compensation consultant to assist with the development of pay strategies and compiling compensation information from peer companies. As part of this process, Pay Governance noted that WaterBridge is a unique organization in the sense that it is a fully-scaled water midstream company that shares a management team with a publicly-traded affiliate land management company, LandBridge. Accordingly, WaterBridge has no direct peers with regards to its management structure and compensation program. Instead of reviewing against a single peer group, Pay Governance performed two separate peer group analyses, one for total cash compensation (base salary and bonus) and a separate analysis for grants of awards made pursuant to a long-term incentive plan. For total cash compensation, Pay Governance reviewed companies that would be considered peers on a combined company basis, i.e., both WaterBridge and LandBridge (collectively, the “Combined Company”). For grants of awards made pursuant to a long-term incentive plan, Pay Governance reviewed against companies that would be considered peers for each of WaterBridge and LandBridge on a standalone basis. In other words, executive compensation was reviewed against the following three separate peer groups: (i) Combined Company basis for both WaterBridge and LandBridge, (ii) for LandBridge, land management companies, minerals and royalty companies and other similar companies only and (iii) for WaterBridge, midstream companies only. The 2025 executive compensation peer groups (the “2025 Peer Groups”)

were composed of the companies listed below, which are primarily midstream energy service companies, oil and gas production companies and royalty and real estate investment trust companies (“REITs”), selected based on size, complexity and the quality of publicly available data with respect to these companies:

After reviewing the executive compensation structures and incentives of comparable peer companies compiled by Pay Governance, our management team then presented this information to the Chairman of our Board and made a recommendation regarding, among other things, the compensation of the Chief Executive Officer and our other NEOs, in each case including base salary, bonus target and long-term incentive awards. Since 2026 will be the Company’s first full year operating post-IPO as a public company, we expect to re-evaluate our peer set for the coming year and we expect the Board to engage a compensation consultant in connection with evaluating a 2027 consolidated compensation plan.

Our NEOs receive a base salary to compensate them for services rendered to the Company. The base salary payable to each NEO is intended to provide a fixed component of compensation reflecting the executive’s skill set, experience, role and responsibilities. In August 2025, in anticipation of the IPO, our Board reevaluated each NEO’s base salary, taking into account a number of factors, including 2025 Peer Groups data, each executive’s experience, individual and Company performance and other individual or organizational circumstances, including the current market and business environments. Based on these considerations, our Board approved increases to the base salaries for each NEO to be effective following the closing of the IPO, which occurred in September 2025. For fiscal year 2025, prior to the IPO, Messrs. Long, Reitz, McNeely, Bolling and Williams’ annual base salaries were as follows: $572,000, $416,000, $374,400, $374,400 and $374,400, respectively. Effective October 1, 2025, the base salary for each of Messrs. Long, Reitz, McNeely, Bolling and Williams is as follows: $850,000, $550,000, $500,000, $450,000 and $450,000.

We maintain an annual performance-based cash bonus program intended to reward achievement relative to annual financial, operational and individual performance objectives, in which Messrs. Long, Reitz, McNeely, Bolling and Williams participated during fiscal year 2025. Under the performance-based cash bonus program, each applicable NEO’s target bonus amount is expressed as a percentage of base salary. In connection with the IPO, the Board approved increases to the target bonus amounts for certain NEOs. For fiscal year 2025, prior to the IPO, the target bonus amount for each of Messrs. Long, Reitz, McNeely, Bolling and Williams was 100%, 80%, 80%, 80% and 80%, respectively. Effective October 1, 2025, the target bonus amount for each of Messrs. Long, Reitz, McNeely, Bolling and Williams is as follows: 125%, 100%, 90%, 80% and 80%, respectively.

Under our annual performance-based cash bonus program, bonus amounts earned were based on our Board’s assessment of individual performance for fiscal year 2025 and final payment amounts are reflected below within the Summary Compensation Table.

Historically, our NEOs received grants of incentive units (“Incentive Units”) from WaterBridge Resources, LLC, WaterBridge II LLC and WaterBridge NDB LLC (“NDB LLC”) as the primary source of equity-based compensation prior to the IPO in order to create alignment with our shareholders. The Incentive Units are structured

as profits interests, rather than capital interests, and do not provide the holder with the rights of an equity holder (such as dividend or voting rights). Grants of Incentive Units are generally subject to a three year service vesting schedule, which is partially met for the NEOs as shown in the “Outstanding Equity Awards at 2025 Fiscal Year-End” table below.

In connection with the IPO in September 2025, we granted restricted stock units (“RSUs”) to the NEOs under the LTIP generally subject to continued employment through each applicable vesting date. LTIP awards are intended to balance retention of our executive team, align our NEOs’ interests with those of our shareholders and tie executive compensation to the long-term performance of the Company. As described above, our management team engaged Pay Governance to assist with designing our 2025 equity compensation program and set the total target LTIP value appropriate for each NEO, taking into account 2025 Peer Groups data and each NEO’s contribution to our success, level of responsibility and experience. Management presented Pay Governance’s findings to the Chairman of our Board, who determined that it was appropriate to allocate each NEO’s LTIP value to equity awards that would vest solely upon continued employment. The RSUs granted on September 18, 2025 in connection with the IPO will vest as to one third of the underlying shares on each of the first, second and third anniversaries of the grant date, subject to each NEO’s continued employment through such date. Following vesting, each RSU will be settled for shares of our Class A shares on a one-for-one basis. For additional information, see the “Grants of Plan-Based Awards for Fiscal Year 2025” and “Outstanding Equity Awards at 2025 Fiscal Year-End” tables below.

We maintain a 401(k) retirement savings plan, or the 401(k) plan, for our employees, including our NEOs, who satisfy certain eligibility requirements. Our NEOs are eligible to participate in the 401(k) plan on the same terms as other full-time employees. The U.S. Internal Revenue Code of 1986, as amended, (the “Code”) allows eligible employees to defer a portion of their compensation, within prescribed limits, on a pre-tax basis through contributions to the 401(k) plan. Currently, we provide matching contributions, 100% of an employee’s salary deferrals, up to a maximum of 7% of salary. An employee can defer up to 90% of their salary.

We believe that providing a vehicle for tax-deferred retirement savings through our 401(k) plan adds to the overall desirability of our compensation package and further incentivizes our employees, including our NEOs, in accordance with our compensation policies.

All of our employees, including our NEOs, are eligible to participate in our health and welfare plans, including:

We did not provide any perquisites or special personal benefits to our NEOs in fiscal year 2025 other than the Company’s payment of life insurance premiums, a monthly company car allowance for certain NEOs, the use of company aircraft and the payment of club membership and dues.

Management believes that the perquisites and other personal benefits provided to the NEOs are reasonable, appropriate and necessary to attract and retain employees for key positions, which, in turn, promotes the long-term interests of our shareholders. The Company has granted club membership to certain NEOs to further business development on behalf of our shareholders, and while such membership is intended to be used for business purposes, members may use the club for personal purposes so long as they pay all incremental costs, other than the annual dues, related to such personal use. Expenses relating to personal use of the club amenities are either reimbursed to the Company by the NEO or paid directly by the NEO. Additionally, each of Messrs. Long and Reitz receive a company car allowance of $1,000 per month.

Our Board has adopted a written policy that sets forth guidelines and procedures regarding personal use of company aircraft. In 2025, personal use of company aircraft was approved in advance by our Chairman on a per use basis. We do not reimburse for taxes relating to any imputed income for personal travel and the personal travel of family members when they accompany an NEO. For fiscal year 2025, the aggregate incremental cost of each NEO’s personal use of company aircraft is described below in the 2025 Summary Compensation Table.

Such aggregate incremental cost of the personal use of our company aircraft reflects the marginal incremental private plane charter costs to the company and excludes any fixed contract costs.

We do not view perquisites or other personal benefits as a significant component of our executive compensation program. We view the personal use of company aircraft to be a significant benefit that assists us in attracting and retaining top talent while allowing our executives to serve the Company without personal travel-related distractions. In the future, we may provide perquisites or other personal benefits in limited circumstances, such as where we believe it is appropriate to assist an individual executive officer in the performance of his or her duties, to make our executive officers more efficient and effective, and for recruitment, motivation or retention purposes. All future practices with respect to perquisites or other personal benefits for our NEOs will be approved and subject to periodic review by our Board and we do not expect such perquisites to become a significant component of our compensation program.

We have not currently entered into employment agreements or severance agreements with any of our NEOs, but each NEO is party to RSU award agreements pursuant to the LTIP and management Incentive Unit (“MIU”) award agreements with regards to incentive units granted by NDB LLC (the “NDB MIUs”), each of which provides the NEOs with certain benefits in the event of a termination or change in control (as defined within each agreement). We believe that providing severance and change in control protections for outstanding equity awards is an important component of a competitive and market aligned executive compensation program. These protections help ensure that we can attract, retain, and appropriately motivate the talent necessary to execute our long-term strategy.

We do not currently grant stock options or stock appreciation rights (“SARs”) as part of our equity compensation programs, therefore we do not maintain a formal policy regarding the timing of stock option or SAR awards. During 2025, while the Board did not grant any stock options or SARs, neither the Board nor the Company times the disclosure of material nonpublic information to affect the value of other types of executive compensation awards granted to any service provider.

We do not make gross-up payments to cover our NEOs’ personal income taxes that may pertain to any of the compensation or perquisites paid or provided by us.

Pursuant to our Insider Trading Policy, the Company’s directors, executive officers and employees (collectively, the “Covered Persons”) may not engage in hedging transactions, short sales or transactions involving Company-based derivative securities, through transactions in Company securities or through the use of financial instruments designed for such purpose. Such hedging transactions, short sales and transactions involving Company-based derivative securities may result in a Covered Person becoming the beneficial owner of such Company securities without taking on the full risks and rewards of ownership, and therefore such Covered Person’s interests may not align with those of the Company’s shareholders generally.

We adopted the WaterBridge Infrastructure LLC Clawback Policy (the “Clawback Policy”), effective as of September 17, 2025. The Clawback Policy is intended to comply with the requirements of Section 10D of the Exchange Act and Section 303A.14 of the NYSE Listing Company Manual. Under the terms of the Clawback Policy, in the event of a restatement of our financial statements due to material non-compliance with any financial reporting requirement under applicable securities laws, the Audit Committee shall take reasonably prompt action to cause the Company to recover the amount of any incentive compensation granted, awarded or paid to a covered employee within the preceding 36-month period to the extent the value of such compensation was in excess of the amount of incentive compensation that would have been granted, awarded or paid had the financial statements been in compliance with the financial reporting requirements (subject to certain limited exceptions). Each executive officer, including our NEOs and certain former executive officers, are considered “Covered Persons” for purposes of the Clawback Policy.

We believe that our compensation program does not encourage excessive or unnecessary risk taking. This is primarily due to the fact that our compensation programs are designed to encourage our NEOs and other employees to focus on both short-term and long-term strategic goals, thereby creating an ownership culture and helping to align the interests of our employees and our shareholders. Accordingly, our compensation program is balanced between short-term and long-term incentive compensation. Short-term incentive compensation is paid annually, but is dependent upon the satisfaction and achievement of quantitative and qualitative factors established by our Board each year.

Overall, we believe that the balance within our compensation program results in an appropriate compensation structure for the Company, and that the program does not pose risks that could have a material adverse effect on our business or financial performance.

The following report of the Audit Committee of the Board on executive compensation shall not be deemed to be “soliciting material” or to be “filed” with the SEC nor shall this information be incorporated by reference into any future filing made with the SEC, whether made before or after the date hereof and irrespective of any general incorporation language in such filing.

The Audit Committee has reviewed and discussed the Compensation Discussion & Analysis required by Item 402(b) of Regulation S-K with management and, based on such review and discussions, the Audit Committee recommended that the Compensation Discussion & Analysis be included in this Proxy Statement.

Respectfully submitted,

The Audit Committee of the Board of Directors

The table below sets forth all the compensation awarded to, earned by, or paid to our NEOs during the fiscal year ended December 31, 2025.

The table below sets forth the awards granted to our NEOs during 2025, including awards under the LTIP.

The following table summarizes the number of share-based awards underlying outstanding equity incentive plan awards for each NEO as of December 31, 2025.

The following table provides information, on an aggregate basis, about the NEOs’ awards that were converted to a single class of common units in connection with our IPO during the fiscal year ended December 31, 2025.

We have not maintained, and do not currently maintain, a defined benefit pension plan or a nonqualified deferred compensation plan providing for retirement benefits.

None of our NEOs is party to an employment agreement. However, each of our NEOs may be entitled to certain benefits upon termination of employment under the terms of their respective equity award agreements, consisting of their NDB MIUs and RSU award agreements entered into pursuant to the LTIP. The table below and the following disclosures discuss the payments and benefits that each of our NEOs would have been eligible to receive upon certain termination events, including terminations in connection with a change in control, assuming that each such termination occurred on December 31, 2025. As a result, the payments and benefits disclosed represent what would have been due and payable to such NEOs under the applicable agreements and plans in existence between each NEO and the Company as of December 31, 2025. This disclosure does not reflect any changes to such agreements or plans, or new agreements or plans adopted, after December 31, 2025, unless specifically stated.

Pursuant to the award agreements governing outstanding LTIP awards held by each NEO, upon a termination of employment without “Cause,” or by the NEO for “Good Reason” (such terms as defined in the award agreement and described below), the RSUs will immediately become fully vested.

Upon termination of employment due to death or disability, then the greater of (i) all unvested RSUs that would have vested within the next year following the termination of the NEO’s employment or service relationship, or (ii) the minimum number of unvested RSUs that, if vested, would cause 50% of the total number of RSUs granted to become vested, will immediately become fully vested.

Upon a termination of employment due to a “Change in Control” (as defined in the LTIP and described below) and the RSUs are not continued, converted, assumed or replaced with a substantially similar award by (a) WaterBridge or (b) a successor entity or its parent or subsidiary, the RSUs will immediately become fully vested.

For each NEO, as of December 31, 2025, the accelerated value of their RSUs would be based upon the number of outstanding RSUs reflected in the “Outstanding Equity Awards at 2025 Fiscal Year-End” table above (as well as the vesting schedule set forth in the footnotes to such table with respect to death or disability situations), multiplied by the price of our Class A shares on December 31, 2025, which was $20.01.

Pursuant to the award agreements governing the outstanding Incentive Units held by each of the NEOs, if the NEO is terminated without “Cause,” (as defined in Incentive Unit award agreement and described below) or the NEO terminates his employment with “Good Reason,” (as defined in Incentive Unit award agreement and described below) all unvested Incentive Units that would have vested during the 12 months following such termination will be deemed to automatically vest as of the termination date.

Upon a termination of a NEO’s employment due to death or disability, the NEO would receive accelerated vesting of an amount that is the greater of (a) the unvested Incentive Units that would have vested during the 12 months following such termination or (b) the number of Incentive Units that equal 50% of the original Incentive Unit grant amount.

In the event that a NEO is terminated for “Cause,” all unvested Incentive Units are immediately forfeited, and one-third of any Incentive Units that had become vested prior to such termination will also be forfeited without consideration.

All unvested Incentive Units held by a NEO upon a termination of employment without good reason, upon the NEO’s bankruptcy, or upon the transfer of that NEO’s awards by contract (including death, divorce, operation of law or otherwise) will be immediately forfeited.

The following table summarizes the compensation and other benefits that would have become payable to each NEO, assuming his employment terminated on December 31, 2025, and assuming a closing price of $20.01 as of December 31, 2025.

Annual compensation for our non-employee directors is currently comprised of cash and equity-based compensation, as set out below. We also reimburse our directors for reasonable out-of-pocket expenses associated with travel to and attendance at our Board and committee meetings. We do not pay for meeting attendance or provide any other benefits or perquisites to our non-employee directors.

For the year ended December 31, 2025, the members of our Board, other than Messrs. Capobianco, Morrow, Sulton, Bayouth, Moore, Eaton, Ms. Harling (collectively, the “Five Point Directors”), Mr. Ritenour and Mr. Long, received compensation for their service on our Board and committees thereof consisting of the items below:

The Company does not pay any compensation to the Five Point Directors or Mr. Ritenour for their service as directors on our Board. For directors appointed or elected after January 1 of a given year, the compensation paid to the non-employee directors will be pro-rated based on the number of days of service.

The following table summarizes the compensation provided to the members of our Board for the year ended December 31, 2025.

Under the director compensation program, members of our Board who are also employees do not receive additional compensation for their service as directors. Each director is entitled to be reimbursed for reasonable out-of-pocket expenses and associated travel incurred to attend meetings and activities of our Board or any of its committees. Each director is also indemnified by us for actions associated with serving as a director to the fullest extent permitted under Delaware law pursuant to indemnification agreements entered into with such director.

The following table sets forth certain information as of December 31, 2025, with respect to compensation plans under which equity securities of WaterBridge are authorized for issuance.

Under the Limited Liability Company Agreement of WBI Operating LLC (“OpCo”), dated as of September 18, 2025 (the “OpCo LLC Agreement”), each holder of a unit representing a limited liability company interest in OpCo (“OpCo Unit”) (other than us), subject to certain limitations, has a right (“Redemption Right”) to cause OpCo to acquire all or a portion of its OpCo Units (along with the cancellation of a corresponding number of our Class B shares) for, at OpCo’s election, (i) Class A shares at a redemption ratio of one Class A share for each OpCo Unit redeemed, subject to applicable conversion rate adjustments, or (ii) cash in an amount equal to the Cash Election Amount (as defined below) of such Class A shares, subject to the Equity Offering Condition (as defined below). OpCo will determine whether to issue Class A shares or pay cash in an amount equal to the Cash Election Amount in lieu of the issuance of Class A shares based on facts in existence at the time of the decision, which we expect would include the relative value of the Class A shares (including the trading price for the Class A shares at the time), the cash purchase price, the availability of other sources of liquidity (such as an issuance of additional common shares) to acquire the OpCo Units and alternative uses for such cash. Alternatively, upon the exercise of the Redemption Right, we (instead of OpCo) will have the right (“Call Right”) to, for administrative convenience, acquire each tendered OpCo Unit directly from the redeeming holder of OpCo Units (“OpCo Unitholder”) for, at our election, (x) one Class A share, subject to applicable conversion rate adjustments, or (y) cash in an amount equal to the Cash Election Amount of such Class A shares, subject to the Equity Offering Condition. We may exercise the Call Right only if an OpCo Unitholder first exercises its Redemption Right, and an OpCo Unitholder may exercise its Redemption Right in its discretion. As the sole managing member of OpCo, our decision to pay the Cash Election Amount upon an exercise of the Redemption Right or Call Right may be made by a conflicts committee consisting solely of independent directors. In connection with any redemption of OpCo Units pursuant to the Redemption Right or acquisition of OpCo Units pursuant to the Call Right, a corresponding number of Class B shares held by the redeeming OpCo Unitholder will be automatically cancelled.

For so long as a redeeming holder and its affiliates own at least 40% of the voting power of the Company, (i) OpCo may elect to settle a redemption by such holder in cash only to the extent that, prior to or contemporaneously with making such election, the Company issues a number of Company Equity Securities (as defined in the OpCo LLC Agreement) at least equal to the number of OpCo Units subject to such redemption and contributes to OpCo an amount in cash equal to the net proceeds received by the Company from the issuance of such Company Equity Securities, and (ii) the Company may make a cash election in connection with its exercise of the Call Right with respect to a redemption by such holder only to the extent that, prior to or contemporaneously with making such election, the Company issues a number of Company Equity Securities at least equal to the number of OpCo Units subject to such redemption (in each case, the “Equity Offering Condition”).

Our LLC Agreement contains provisions effectively linking each OpCo Unit with one of our Class B shares such that Class B shares cannot be transferred without transferring an equal number of OpCo Units and vice versa.

As the OpCo Unitholders (other than us) cause their OpCo Units to be redeemed, holding other assumptions constant, our membership interest in OpCo will be correspondingly increased, the number of Class A shares outstanding will be increased, and the number of Class B shares will be decreased.

“Cash Election Amount” means, with respect to the Class A shares to be delivered to the redeeming OpCo Unitholder by OpCo pursuant to the Redemption Right or the Call Right, as applicable, (i) the amount of cash that would be received if the number of Class A shares to which the redeeming OpCo Unitholder would otherwise be entitled were sold at a per share price equal to the trailing 10 day volume weighted average price of a Class A share on such redemption date, net of actual or deemed offering expenses or (ii) if the Class A shares no longer trade on a securities exchange or automated or electronic quotation system, an amount equal to the Fair Market Value (as defined in the OpCo LLC Agreement) of one Class A share that would be obtained in an arms’ length transaction for cash between an informed and willing buyer and an informed and willing seller, neither of whom is under any compulsion to buy or sell and without regard to the particular circumstances of the buyer or seller.

Under the OpCo LLC Agreement and in our capacity as the managing member of OpCo, subject to the obligation of OpCo to make tax distributions and to reimburse us for our corporate and other overhead expenses, we have the right to determine when distributions will be paid to the OpCo Unitholders and the amount of any such distributions.

The OpCo Unitholders, including us, are allocated their proportionate share of any taxable income or loss of OpCo pursuant to the OpCo LLC Agreement and generally incur U.S. federal, state and local income taxes on their

proportionate share of any net taxable income of OpCo. Net profits and net losses of OpCo generally are allocated to OpCo Unitholders on a pro rata basis in accordance with their respective percentage ownership of OpCo Units, except that certain non pro rata adjustments are required to be made to reflect built in gains and losses and tax depreciation and amortization with respect to such built in gains and losses. The OpCo LLC Agreement provides, subject to the terms of any current or future debt or other arrangements, for: (i) pro rata tax distributions to the OpCo Unitholders in an amount generally intended to allow us to satisfy our actual income tax liabilities with respect to our allocable share of the income of OpCo; (ii) pro rata tax distributions to the OpCo Unitholders in an amount generally intended to allow us to make payments under the Tax Receivable Agreement that we entered into with OpCo and the TRA Holders (as defined below) in connection with the consummation of the IPO and any subsequent tax receivable agreements that we may enter into in connection with future acquisitions; and (iii) to the extent cash is available, additional pro rata tax distributions to the OpCo Unitholders in an amount generally intended to allow the OpCo Unitholders (other than us) to satisfy their estimated tax liabilities with respect to their allocable share of the income of OpCo, based on certain assumptions and conventions.

The OpCo LLC Agreement provides that, except as otherwise determined by us or in connection with the exercise of the Call Right, at any time we issue a Class A share or any other equity security, the net proceeds received by us with respect to such issuance, if any, shall be concurrently invested in OpCo, and OpCo shall issue to us one OpCo Unit or other economically equivalent equity interest. Conversely, if at any time any Class A shares are redeemed, repurchased or otherwise acquired, OpCo shall redeem, repurchase or otherwise acquire an equal number of OpCo Units held by us, upon the same terms and for the same price, as the Class A shares are redeemed, repurchased or otherwise acquired.

Under the OpCo LLC Agreement, the members have agreed that the Five Point Members and Devon Holdco, as well as their affiliates, are permitted to engage in business activities or invest in or acquire businesses that may compete with our business or do business with any client of ours.

As a result of our organizational structure, we obtained, in connection with the consummation of the IPO, existing tax basis in certain assets of OpCo and certain of its direct or indirect subsidiaries, including assets that are subject to depreciation or amortization (the “Existing Basis”) and certain historic net operating loss carryforwards and similar attributes of WB 892 (“Historical NOLs”). We expect to obtain tax basis adjustments, including an increase in our allocable share of existing tax basis, (such basis increase, the “Basis Adjustments”) resulting from (i) our acquisition (or deemed acquisition for U.S. federal income tax purposes) of OpCo Units in connection with the Redemption Right or Call Right as described under “Certain Relationships and Related Party Transactions—OpCo LLC Agreement,” (ii) certain distributions (or deemed distributions) by OpCo, and (iii) payments made under the Tax Receivable Agreement as well as deductions attributable to imputed interest and other payments of interest pursuant to the Tax Receivable Agreement (such deductions, the “Interest Deductions”).

The parties to a tax receivable agreement (the “Tax Receivable Agreement”) with WBR Holdings, NDB Holdings LLC, Desert Environmental Holdings LLC, Devon Holdco, Elda River Infrastructure LLC (“Elda River”), Ashburton Investment Private Limited (“Ashburton” and, collectively with the Five Point Members, Devon Holdco and Elda River, the “Legacy Owners”) and OpCo (each such person and its permitted transferees, a “TRA Holder”) intend to treat each redemption or exchange of OpCo Units pursuant to the OpCo LLC Agreement as our direct purchase of OpCo Units from an OpCo Unitholder for U.S. federal income and other applicable tax purposes, regardless of whether such OpCo Units are surrendered by an OpCo Unitholder to OpCo for redemption, or, to the extent there is cash available from a contemporaneous public offering or private sale of our Class A shares by us and we so authorize, sold directly to us. Any Existing Basis, Basis Adjustments, Historical NOLs and Interest Deductions may have the effect of reducing the amount of taxes that we would otherwise pay in the future to various tax authorities. The Existing Basis, Basis Adjustments and Interest Deductions may also decrease gains (or increase losses) on future dispositions of certain assets to the extent tax basis is allocated to those assets.

In connection with the consummation of the IPO, we entered into a Tax Receivable Agreement with OpCo and the TRA Holders. The Tax Receivable Agreement provides for the payment by us to the TRA Holders of 85% of the amount of cash tax savings, if any, that we actually realize (or in some circumstances are deemed to realize) as a result of the Existing Basis, Basis Adjustments, Historical NOLs and Interest Deductions, including those resulting from payments pursuant to the Tax Receivable Agreement. OpCo and its applicable subsidiaries will have an election under Section 754 of the Code in effect for each taxable year in which a redemption or exchange of OpCo

Units for our Class A shares or cash occurs. Assuming no material changes in the relevant tax law and that we earn sufficient taxable income to realize all tax benefits that are subject to the Tax Receivable Agreement, we expect that the tax savings associated with the (i) Existing Basis, (ii) Basis Adjustments, (iii) Historical NOLs and (iv) Interest Deductions would aggregate to approximately $952.9 million over 20 years from December 31, 2025 based on a $20.01 per share trading price of our Class A shares and assuming all future redemptions or exchanges would occur on December 31, 2025 at the same assumed price per share.

Under such scenario, assuming future payments are made on the due date (with extension) of each relevant U.S. federal income tax return, we would be required to pay approximately 85% of such amount, or approximately $810.0 million, over the 20-year period from December 31, 2025, and we would benefit from the remaining 15% of the tax benefits. These Tax Receivable Agreement payments are not conditioned upon any continued ownership interest in either OpCo or us by any TRA Holder. The rights of each TRA Holder under the Tax Receivable Agreement are assignable regardless of whether the underlying OpCo Units are also assigned. In general, the TRA Holders’ rights under the Tax Receivable Agreement may not be assigned, sold, pledged or otherwise alienated to any person, other than certain permitted transferees, without such person becoming a party to the Tax Receivable Agreement and agreeing to succeed to the applicable TRA Holders’ interest therein.

The actual Existing Basis, Basis Adjustments, Historical NOLs and Interest Deductions, as well as any amounts paid to the TRA Holders under the Tax Receivable Agreement, vary depending on a number of factors, including:

For purposes of the Tax Receivable Agreement, cash savings in income taxes will be computed by comparing our actual income tax liability to the amount of such taxes that we would have been required to pay had there been no Existing Basis, Basis Adjustments, Historical NOLs and Interest Deductions; provided that, for purposes of determining cash savings with respect to state and local income taxes an assumed tax rate will be used. The Tax Receivable Agreement generally applies to each of our taxable years. There is no maximum term for the Tax Receivable Agreement, although, as discussed further below, the Tax Receivable Agreement may be terminated by us pursuant to an early termination procedure or upon the occurrence of certain events, in each case, that requires us to pay the TRA Holders an agreed upon amount equal to the estimated present value of the remaining payments to be made under the agreement (calculated based on certain assumptions, including regarding tax rates and use of the Basis Adjustments and Interest Deductions).

The payment obligations under the Tax Receivable Agreement are obligations of us and not OpCo. Although the actual timing and amount of any payments that may be made under the Tax Receivable Agreement will vary, it is expected that the payments that we may be required to make to the TRA Holders could be substantial. Any payments made by us to the TRA Holders under the Tax Receivable Agreement generally reduces the amount of overall cash flow that might have otherwise been available to us and, to the extent that we are unable to make payments under the Tax Receivable Agreement for any reason, the unpaid amounts generally are deferred and accrue interest until paid by us; provided, however, that nonpayment for a specified period may constitute a material breach of a material obligation under the Tax Receivable Agreement and, therefore, may accelerate payments due under the Tax Receivable Agreement, which could be substantial. We fund ordinary course payments under the Tax Receivable Agreement from cash flow from operations of our subsidiaries, available cash or available borrowings under our existing credit facilities or any future debt agreements.

Decisions made by us in the course of running our business, such as with respect to mergers, asset sales, other forms of business combinations or other changes in control, may influence the timing and amount of payments that we are required to make to a TRA Holder under the Tax Receivable Agreement. For example, the earlier disposition of assets following an exchange or acquisition transaction will generally accelerate payments under the Tax Receivable Agreement and increase the present value of such payments.

The Tax Receivable Agreement provides that if (a) we materially breach any of our material obligations under the Tax Receivable Agreement or (b) we elect an early termination of the Tax Receivable Agreement, then our obligations, or our successor’s obligations, under the Tax Receivable Agreement accelerate and become due and payable, based on certain assumptions, including an assumption that we have sufficient taxable income to fully use all potential future tax benefits that are subject to the Tax Receivable Agreement. In those circumstances, TRA Holders would be deemed to exchange any remaining outstanding OpCo Units for our Class A shares and the TRA Holders generally would be entitled to payments under the Tax Receivable Agreement resulting from such deemed exchanges. We may elect to completely terminate the Tax Receivable Agreement early only with the written approval of a majority of our “independent directors” (within the meaning of the rules of the NYSE and NYSE Texas). The amount due and payable in those circumstances is based on the present value (at a discount rate of SOFR plus 100 basis points) of projected future tax benefits that are based on certain assumptions, including an assumption that we would have sufficient taxable income to fully use all potential future tax benefits that are subject to the Tax Receivable Agreement. Based on such assumptions, if we were to exercise our termination right, or the Tax Receivable Agreement is otherwise terminated, immediately following the consummation of the IPO, the aggregate amount of the termination payments would be approximately $589.2 million. In addition, upon a change of control our (or our successor’s) payments under the Tax Receivable Agreement for each taxable year after any such event would be based on certain assumptions, including an assumption that we would have sufficient taxable income to fully use all potential tax benefits that are subject to the Tax Receivable Agreement.

As a result of the foregoing, we could be required to make an immediate cash payment, possibly significantly in advance of the actual realization, if any, of such future cash tax savings. We also could be required to make cash payments to the TRA Holders that are greater than 85% of the actual benefits we ultimately realize in respect of the tax benefits that are subject to the Tax Receivable Agreement. In these situations, our obligations under the Tax Receivable Agreement could have a substantial negative impact on our liquidity and could have the effect of deferring or preventing certain mergers, asset sales, other forms of business combination, or other changes of control. There can be no assurance that we will be able to finance our obligations under the Tax Receivable Agreement.

Payments under the Tax Receivable Agreement are based on the tax reporting positions that we determine, which are complex and factual in nature, and the IRS or another taxing authority may challenge all or any part of the Basis Adjustments, as well as other tax positions that we take, and a court may sustain such a challenge. We will not be reimbursed for any cash payments previously made to the TRA Holders pursuant to the Tax Receivable Agreement if any tax benefits initially claimed by us are subsequently challenged by a taxing authority and ultimately disallowed. Instead, any excess cash payments made by us to a TRA Holder will be netted against future cash payments, if any, we might otherwise be required to make under the terms of the Tax Receivable Agreement to such TRA Holders. However, a challenge to any tax benefits initially claimed by us may not arise for a number of years following the initial time of such payment or, even if challenged early, such excess cash payment may be greater than the amount

of future cash payments, if any, we might otherwise be required to make under the terms of the Tax Receivable Agreement and, as a result, there might not be future cash payments from which to net against. As a result, it is possible that we could make cash payments under the Tax Receivable Agreement that are substantially greater than 85% of our actual cash tax savings.

We will have full responsibility for, and sole discretion over, all our and OpCo’s tax matters, including the filing and amendment of all tax returns and claims for refund and defense of all tax contests, subject to certain participation and approval rights held by certain TRA Holders. If the outcome of any challenge to all or part of the Existing Basis, Basis Adjustments, Interest Deductions or other tax benefits we claim would reasonably be expected to materially affect a TRA Holder’s rights and obligations under the Tax Receivable Agreement, then we will not be permitted to settle such challenge without the consent (not to be unreasonably withheld or delayed) of certain TRA Holders. The interests of such TRA Holders in any such challenge may differ from or conflict with our and our investors’ interests, and such TRA Holders may exercise their consent rights relating to any such challenge in a manner adverse to our and our investors’ interests.

Under the Tax Receivable Agreement, we are required to provide each TRA Holder that holds an interest in the Tax Receivable Agreement and to which a tax benefit or detriment is attributable with a schedule showing the calculation of payments that are due under the Tax Receivable Agreement with respect to each taxable year with respect to which a payment obligation to such holder arises within 90 days after filing our U.S. federal income tax return for such taxable year. This calculation will be based upon the advice of our tax advisors. Payments are generally due under the Tax Receivable Agreement within a specified period of time following the filing of our tax return for the taxable year with respect to which the payment obligation arises, although interest on such payments will begin to accrue at a rate of SOFR plus 100 basis points from the due date (without extensions) of such tax return. Some late payments that may be made under the Tax Receivable Agreement will continue to accrue interest at a rate of SOFR plus 500 basis points until such payments are made, including any late payments that we may subsequently make because we did not have enough available cash to satisfy our payment obligations at the time at which they originally arose.

In connection with the closing of the IPO, we entered into a registration rights agreement with the Five Point Members, Devon Holdco, Elda River and Ashburton (the “Registration Rights Agreement”) pursuant to which we agreed to register under the federal securities laws the offer and resale of all Class A shares owned by, or underlying the Class B shares and OpCo Units owned by, our Legacy Owners or certain of their affiliates or permitted transferees. These registration rights are subject to certain conditions and limitations, including the right of the underwriters to limit the number of Class A shares to be included in a registration statement and our right to delay or withdraw a registration statement under certain circumstances. Subject to certain exceptions, if at any time we propose to register an offering of Class A shares or conduct an underwritten offering, regardless of whether for our own account, then we must notify the holders of Registrable Securities (as defined in the Registration Rights Agreement) or their permitted transferees of such proposal, to allow them to include a specified number of their Class A shares in that registration statement or underwritten offering, as applicable, including Class A shares issuable upon the redemption of the OpCo Units and the cancellation of a corresponding number of our Class B shares.

In connection with the consummation of the IPO, we and certain of our affiliates entered into a contribution and reorganization agreement (the “Contribution and Reorganization Agreement”) that governed the consummation of our IPO, our related corporate reorganization and transactions in connection therewith (the “WaterBridge Combination”). Pursuant to the Contribution and Reorganization Agreement, (i) the Five Point Members, Devon Holdco and Elda River contributed approximately $80,200 in cash to WaterBridge in exchange for the issuance of an aggregate 80,190,150 Class B shares to the Five Point Members, Devon Holdco and Elda River and (ii) WaterBridge issued 3,411,735 Class A shares and 3,398,115 Class A shares to WBR Holdings and Ashburton, respectively, in exchange for the equity interests in WaterBridge Equity Finance LLC directly or indirectly held by each of them and contributed to WaterBridge in connection with the WaterBridge Combination.

In connection with the closing of the IPO, we entered into a shareholders’ agreement (the “Shareholders’ Agreement”) with the Five Point Members and Devon Holdco. As discussed further below, the Shareholders’ Agreement provides certain rights to the Five Point Members and Devon Holdco.

Under the Shareholders’ Agreement, each of the Five Point Members and Devon Holdco agreed with us that such shareholder will take all necessary action (including voting or causing to be voted all of our common shares beneficially owned by each such shareholder) so that no amendment is made to our LLC Agreement in effect as of the date of the Shareholders’ Agreement that would (a) add restrictions to the transferability of our shares by any such shareholder that are beyond those provided for in our LLC Agreement, the Shareholders’ Agreement or applicable securities laws or (b) nullify any of the rights of any Shareholder (as defined in the Shareholders’ Agreement), which rights are explicitly provided for in the Shareholders’ Agreement, unless, in each such case, such amendment is approved by the Five Point Members. To the extent such amendment would adversely and disproportionately affect the rights of Devon Holdco with respect to any of our securities owned by Devon Holdco or its affiliates under the Shareholders’ Agreement compared to the Five Point Members, then such amendment shall also require the approval of Devon Holdco.

The Shareholders’ Agreement provides that, subject to compliance with applicable law and stock exchange rules, (a) for so long as the Five Point Members and certain affiliates beneficially own at least 40% of our outstanding common shares, the Five Point Members shall be entitled to designate a number of directors equal to a majority of the Board, plus one director; (b) for so long as the Five Point Members and such affiliates beneficially own at least 30%, 20% and 10% of our outstanding common shares, the Five Point Members shall be entitled to designate at least three directors, two directors and one director, respectively; and (c) for so long as Devon Holdco and its affiliates beneficially own at least 10% of our outstanding common shares, Devon Holdco shall be entitled to designate one director to the Board. For so long as any initial shareholder party thereto is entitled to designate one or more nominees to the Board and notifies the Board of its desire to remove, with or without cause, any director previously designated by it to the Board, we are required to take all necessary action to cause such removal. For so long as the Five Point Members or Devon Holdco, as the case may be, collectively with their affiliates, beneficially own at least 5% of our outstanding common shares, the Five Point Members, as a group, and Devon Holdco will each have the right to appoint one board observer, who will be entitled to attend all meetings of the Board in a non-voting, observer capacity; provided, however, that board observers may be excluded from certain materials or meetings necessary to preserve legal privilege, address conflicts of interest or protect sensitive information.

The Shareholders’ Agreement will terminate with respect to each shareholder party thereto upon such shareholder and its affiliates ceasing to beneficially own at least 5% of our outstanding common shares.

Certain of our subsidiaries (collectively, the “Manager”) are party to a shared services agreement (the “Shared Services Agreement”), with LandBridge, pursuant to which the Manager provides our senior executive management team, as well as general, administrative and overhead services, to support each such entity’s businesses and development activities. Such general and administrative services include, but are not limited to, legal services, information technology, accounting and financial and tax services. Pursuant to the Shared Services Agreement, the Manager also provides operational and maintenance services, such as project and construction management, and provides operating materials and equipment. The term of the Shared Services Agreement continues until terminated by mutual agreement. As consideration for the services rendered pursuant to the Shared Services Agreement, such entities reimburse the Manager for all fees and expenses incurred by the Manager or its affiliates or agents in connection therewith. Each entity pays the Manager its proportionate share of its total costs as determined under the Shared Services Agreement. Such payments are intended to cover certain allocated compensation and benefits costs for the employees, including our management team, that provide services to such entities. Such allocations are made by the Manager among such entities in good faith based upon the time that is devoted by our employees, including our management team, to such entities, but there is not a specific allocation of value to any one person or any one item of compensation or benefits paid or provided to any specific person. For the year ended December 31, 2025, the Manager received approximately $17.2 million for shared services and direct cost reimbursements from LandBridge.

In addition to the Shared Services Agreement, we reimburse Five Point for our usage of its geographic information services as well as legal services as necessary to support our operations. For the year ended December 31, 2025, we paid Five Point $1.5 million in reimbursements in connection with this arrangement.

In the normal course of business, we enter into transactions with related parties in which certain of our affiliates hold financial interests, which are described in more detail below.
