NOTICE OF ANNUAL MEETING OF LIMITED PARTNERS TO BE HELD ON JUNE 13, 2024

Dear Unitholders of Black Stone Minerals, L.P.:

Notice is hereby given that the 2024 annual meeting of limited partners (the “Annual Meeting”) of Black Stone Minerals, L.P. (the “Partnership”) will be held on June 13, 2024 at 12:00 p.m., Central Time, via live webcast, for the following purposes:

You may attend the Annual Meeting via the internet at https://web.lumiconnect.com/255252993. Because the Annual Meeting is completely virtual and being conducted via the Internet, you will not be able to attend the meeting in person.

The Board has fixed the close of business on April 15, 2024 as the record date for the Annual Meeting. Holders of record of the Partnership’s common units and preferred units as of the close of business on such date are entitled to notice of, and to vote at, the Annual Meeting.

Pursuant to the rules adopted by the Securities and Exchange Commission, the Partnership is providing access to its proxy materials primarily via the Internet, rather than mailing paper copies of these materials to each unitholder. On or about April 29, 2024, the Partnership began mailing a Notice of Internet Availability of Proxy Materials to its unitholders of record detailing how to access the proxy materials electronically and how to submit a proxy by telephone, Internet, or mail or vote during the Annual Meeting. The Notice of Internet Availability of Proxy Materials also provides instructions on how to request and obtain paper copies of the proxy materials.

If your units are held in street name, you will receive instructions from the holder of record detailing how to direct the voting of your units. Internet and/or telephone voting will also be offered to unitholders holding units in street name.

The Partnership urges you to review the proxy materials carefully and to submit your proxy or voting instructions as soon as possible so that your units will be represented at the Annual Meeting.

GENERAL INFORMATION

Purpose of the Annual Meeting

The purpose of the Annual Meeting is for our unitholders to consider and act upon the proposals described in this Proxy Statement and upon any other matters that properly come before the Annual Meeting or any adjournment or postponement thereof. In addition, management will report on our performance and respond to questions from unitholders.

Proposals to be Voted Upon at the Annual Meeting

At the Annual Meeting, unitholders will be asked to consider and vote upon the following proposals:

1

In addition, any other matters that properly come before the Annual Meeting or any adjournments or postponements thereof will be considered. Management is not presently aware of any other business to properly come before the Annual Meeting.

Recommendation of the Board

The Board recommends that you vote “FOR ALL” of the director nominees to the Board set forth in this Proxy Statement (Proposal 1), “FOR” the ratification of the appointment of Ernst & Young as our independent registered public accounting firm for the year ending December 31, 2024 (Proposal 2), “FOR” the approval, on a non-binding advisory basis, of the compensation of our named executive officers for the year ended December 31, 2023 (Proposal 3), and “FOR” the approval, on a non-binding advisory basis, of holding the advisory vote on the compensation of our named executive offers every “ONE YEAR” (Proposal 4).

Right to Vote

Pursuant to the First Amended and Restated Agreement of Limited Partnership of Black Stone Minerals, L.P., dated May 6, 2015, as amended (the “Partnership Agreement”), only holders of common units and preferred units on the Record Date (as defined below) are entitled to notice of, and to vote at, the Annual Meeting. Such unitholders will vote together as a single class. Holders of common units are entitled to one vote per unit at the Annual Meeting, and holders of preferred units are entitled to vote their preferred units on an “as-converted basis.”

If any person or group (other than the limited partners of Black Stone Minerals Company, L.P. (“BSMC”) prior to our initial public offering; their transferees; persons who acquired their units with the prior approval of the Board; holders of preferred units in connection with any vote, consent, or approval of the preferred units as a separate class; and persons who own 15% or more of any class as a result of any redemption or purchase of any other person’s units or similar action by us or any conversion of the preferred units at our option) beneficially owns 15% or more of any class of common units or preferred units as of the Record Date, that person or group will not be entitled to notice of, nor to vote at, the Annual Meeting.

In addition, solely with respect to the election of directors, the Partnership Agreement provides that we and the General Partner are not entitled to vote our units, if any, and such units will not be counted when calculating the required votes for the election of directors and will not be deemed outstanding for purposes of determining a quorum for the Annual Meeting. These units will not be treated as a separate class of partnership securities for purposes of the Partnership Agreement.

The Board has fixed the close of business on April 15, 2024 as the record date (the “Record Date”) for the determination of unitholders entitled to notice of, and to vote at, the Annual Meeting. As of close of business on the Record Date, there were, outstanding and entitled to vote, 210,702,620 common units held by 359 holders of record and 14,711,219 preferred units held by 1 holder of record (representing 14,711,219 common units on an as-converted basis). In the aggregate, as of the Record Date, there were outstanding and entitled to vote 225,413,839 units.

A list of holders of record as of the Record Date will be available for inspection during ordinary business hours at our offices located at 1001 Fannin Street, Suite 2020, Houston, Texas, 77002 from April 29, 2024 to the date of our virtual Annual Meeting. A copy of this list will be provided to you at no charge upon written request to Investor Relations at Black Stone Minerals, L. P. at the above listed address. The list will also be available for inspection by any unitholder in attendance at the Annual Meeting.

Units held in a nominee or street name account will be voted by the broker or other nominee in accordance with the instruction of the beneficial owner unless the arrangement between the beneficial owner and his nominee provides otherwise.

Voting Procedures

Registered Holders

If, on the Record Date, you hold units that are registered directly in your name with our transfer agent, Equiniti Trust Company, LLC (“Equiniti”), you are considered a registered holder with respect to those units and entitled to notice of and to vote at the Annual Meeting. On or about April 29, 2024, we began mailing a Notice of Internet Availability of Proxy Materials to our registered holders of record detailing how to access the proxy materials electronically and how to submit a proxy by telephone, Internet, or mail or vote during the Annual Meeting. As a registered holder of record, you may vote your units by one of the following methods:

If you submit an executed proxy but do not give voting instructions as to how your units should be voted on a particular proposal at the Annual Meeting, your units will be voted in accordance with the recommendation of the Board as stated in this Proxy Statement. If you are a registered holder and you do not submit a proxy or vote virtually during the Annual Meeting, your units will not be voted on the proposals or counted for the purpose of establishing a quorum at the Annual Meeting.

If you receive more than one Notice of Internet Availability of Proxy Materials, it is because your units are registered in more than one name or are registered in different accounts. Please follow the instructions on each Notice of Internet Availability of Proxy Materials received to ensure that all your units are voted.

Beneficial Owners

If you hold units in an account with a brokerage firm, bank, or other nominee, then you are a beneficial owner with respect to these units and hold such units in “street name.” If you are a beneficial owner of units on the Record Date, the brokerage firm, bank, or other nominee (the “intermediary”) will provide instructions detailing how to direct the voting of your units through the intermediary. The intermediary that holds your units is considered the holder of record for purposes of voting at the Annual Meeting. Internet and/or telephone voting is also generally offered to unitholders holding units in street name, but you must follow the instructions provided by the intermediary.

As a beneficial owner, you are also invited to attend the Annual Meeting virtually. However, since you are not the holder of record, you may not vote your units during the Annual Meeting unless you follow your intermediary’s procedures for obtaining a legal proxy.

3

After obtaining a valid legal proxy from your intermediary, to then register to vote at the Annual Meeting virtually, you must submit proof of your legal proxy reflecting the number of your units along with your name and email address to AST. Requests for registration should be directed to proxy@equiniti.com or to facsimile number 718-765-8730. Written requests can be mailed to:

Equiniti Trust Company LLC

Attn: Proxy Tabulation Department

55 Challenger Road, Suite 200B 2^nd Floor

Ridgefield Park, NJ 07660

Requests for registration must be labeled as “Legal Proxy” and be received no later than 4:00 p.m., Central Time, on May 30, 2024.

You will receive a confirmation of your registration and an 11-digit voter control number by email issued by Equiniti after we receive your registration materials. You may attend the Annual Meeting virtually and vote your units at https://web.lumiconnect.com/255252993 during the meeting. The password for the meeting is “bsmvirt24”. Follow the instructions provided to vote. We encourage you to access the meeting prior to the start time so that you have sufficient time to check in. Please read “—Attending the Annual Meeting.”

If you do not vote your units during the Annual Meeting or instruct the intermediary how to vote your units, the intermediary may vote your units as it decides for each matter for which it has discretionary authority under New York Stock Exchange (“NYSE”) rules. The election of directors (Proposal 1), approval of the compensation of our named executive officers (Proposal 3), and approval of the preferred frequency of advisory votes on executive compensation (Proposal 4) are non-discretionary matters, meaning that intermediaries do not have discretionary authority to vote unless they receive timely instruction from you. As such, for Proposals 1, 3 and 4 to be voted on at the Annual Meeting, you must provide timely instructions on how the intermediary should vote your units. When an intermediary does not have discretion to vote on a particular matter, you have not given timely instructions on how the intermediary should vote your units, and the intermediary indicates it does not have authority to vote such units on its proxy, a “broker non-vote” results. Although any broker non-vote would be counted as present at the Annual Meeting for purposes of determining a quorum, it would be treated as not entitled to vote with respect to non-discretionary matters, and, as such, broker non-votes will not be counted as a vote “FOR” or “AGAINST” Proposals 1, 3 and 4.

The ratification of the appointment of our independent registered public accounting firm for the year ending December 31, 2024 (Proposal 2) is a discretionary matter on which intermediaries may vote in the absence of timely instructions from you.

Attending the Annual Meeting

Only unitholders of record or their legal proxy holders as of the Record Date may attend the Annual Meeting. This year’s annual meeting will be a virtual meeting via live webcast on the Internet. You will be able to attend the Annual Meeting, vote and submit your questions during the meeting by visiting https://web.lumiconnect.com/255252993. In order to vote or submit a question during the Annual Meeting, you will need an 11-digit voter control number included on your Notice of Internet Availability of Proxy Materials or proxy card, or provided by Equiniti if you are a beneficial owner with the password of “bsmvirt24”. If you do not have an 11-digit voter control number issued by Equiniti you will be able to listen to the meeting only by registering as a guest. You will not be able to vote or submit your questions during the meeting.

The Annual Meeting will be held at 12:00 p.m., Central Time.

4

Revoking Your Proxy

If you are a registered holder, you may change your vote or revoke your proxy at any time before the units are voted at the Annual Meeting by:

If you are a beneficial owner and you submit voting instructions to your intermediary, you may change your vote by submitting new voting instructions in accordance with such intermediary’s procedures.

Quorum

The holders of a majority of the common units and preferred units (on an as-converted basis), in the aggregate, represented by virtual attendance or by proxy shall constitute a quorum at the Annual Meeting, unless any such action requires approval by holders of a greater percentage of the units, in which case the quorum shall be the greater percentage. Proxies received but marked as abstentions and broker non-votes will be included in the number of units considered to be present at the Annual Meeting for purposes of establishing a quorum. The unitholders present at a duly called or held meeting at which a quorum is present may continue to transact business until adjournment, notwithstanding the withdrawal of enough unitholders to leave less than a quorum. In the absence of a quorum, the Annual Meeting may be adjourned from time to time until a quorum is obtained, but no other business may be transacted, except as otherwise provided in the Partnership Agreement.

Required Votes

Election of Directors (Proposal 1)

Pursuant to the Partnership Agreement, the directors of the Board are elected by a plurality of the votes cast by the unitholders entitled to vote at the Annual Meeting. Each unitholder entitled to vote at the Annual Meeting is entitled to cumulate his or her votes in the election of directors and give one candidate, or divide among any number of candidates, a number of votes equal to the product of (x) the number of common units and preferred units (on an as-converted basis) held by the unitholder, multiplied by (y) the number of directors to be elected at the Annual Meeting. Abstentions and broker non-votes will be counted for purposes of establishing quorum but otherwise will have no effect on the election of directors. In addition, as described below under “Majority Voting Policy,” each of the incumbent director nominees is required to tender his or her resignation as a director if he or she fails to receive at least a majority vote election to the Board.

Ratification of our Independent Registered Public Accounting Firm (Proposal 2)

Pursuant to the Partnership Agreement, the proposal to ratify the appointment of Ernst & Young as our independent registered public accounting firm for the year ending December 31, 2024 requires approval by a majority of the votes cast by the unitholders entitled to vote at the Annual Meeting. Abstentions will be counted for purposes of establishing quorum but otherwise will have no effect on this proposal. Because intermediaries will have discretion to vote units without the direction of their clients with respect to this proposal, there will not be any broker non-votes with respect to this proposal.

5

Approval of the Compensation of our Named Executive Officers (Proposal 3)

Pursuant to the Partnership Agreement, the proposal to approve, on a non-binding advisory basis, the compensation of our named executive officers for the year ended December 31, 2023 requires approval by a majority of the votes cast by the unitholders entitled to vote at the virtual Annual Meeting. Abstentions and broker non-votes will be counted for purposes of establishing quorum but otherwise will have no effect on this proposal. While this vote does not bind the Board to any particular action, the Board values the input of the limited partners and will take into account the outcome of this vote when considering future compensation arrangements.

Approval of the Preferred Frequency of Advisory Votes on Executive Compensation (Proposal 4)

Pursuant to the Partnership Agreement, the proposal to approve, on a non-binding advisory basis, the preferred frequency of advisory votes on executive compensation requires approval by a majority of the votes cast by the unitholders entitled to vote at the Annual Meeting. Abstentions and broker non-votes will be counted for purposes of establishing quorum but otherwise will have no effect on this proposal. This advisory vote on the frequency of future say-on-pay votes is not binding on the Partnership or the Board. However, the Board values the input of the limited partners and will take into account the result of this vote when determining the frequency of future say-on-pay votes.

Solicitation of Proxies

This solicitation of proxies is being made by the Board, and we will bear all costs incurred in the solicitation of proxies. This includes the charges and expenses of brokerage firms and others for forwarding solicitation material to beneficial owners of our units. We may solicit proxies by mail, telephone, or via the Internet through our executive officers, directors, and other management employees, who will receive no additional compensation for their services.

2023 Annual Report

Our Annual Report on Form 10-K for the fiscal year ended December 31, 2023 is available on our website at www.blackstoneminerals.com in the “SEC Filings” subsection of the “Investors” section. A copy of our Annual Report on Form 10-K for the fiscal year ended December 31, 2023, including the financial statements and the financial statement schedules, if any, but not including exhibits, will be furnished at no charge to each unitholder to whom a Notice of Internet Availability of Proxy Materials is delivered upon the written request of such person addressed to Investor Relations at Black Stone Minerals, L.P., 1001 Fannin Street, Suite 2020, Houston, Texas, 77002.

PROPOSAL 1—ELECTION OF DIRECTORS

At the recommendation of the Nominating and Governance Committee of the Board, the Board has nominated the following individuals for election as directors of the Board, each to serve until the 2025 Annual Meeting and thereafter until such director’s successor shall have been duly elected and qualified, or until such director’s earlier death, resignation, or removal:

D. Mark DeWalch

Jerry V. Kyle, Jr.

Michael C. Linn

Each director nominee is currently serving on the Board. Certain individual qualifications and skills of our directors that contribute to the Board’s effectiveness as a whole are described below in each director’s biographical information under the heading “Executive Officers and Directors.”

The election of directors in this Proposal 1 requires the affirmative vote of a plurality of the votes cast by the unitholders entitled to vote at the Annual Meeting. Each unitholder entitled to vote at the Annual Meeting is entitled to cumulate his or her votes in the election of directors and give one candidate, or divide among any number of candidates, a number of votes equal to the product of (x) the number of common units and preferred units (on an as-converted basis) held by the unitholder, multiplied by (y) the number of directors to be elected at the Annual Meeting. Abstentions and broker non-votes will have no effect on the election of directors. In addition, as described below under “Majority Voting Policy,” each of the incumbent director nominees is required to tender his or her resignation as a director if he or she fails to receive at least a majority vote election to the Board.

Unless otherwise indicated on the proxy, the persons named as proxies will vote “FOR ALL” of the nominees listed above. We have no reason to believe that any of the nominees will be unable to serve if elected; however, should any of the nominees become unable to serve prior to the Annual Meeting, the proxies will be voted for the election of such other persons as may be nominated by the Board.

THE BOARD UNANIMOUSLY RECOMMENDS A VOTE “FOR ALL” OF THE DIRECTOR NOMINEES.

GOVERNANCE MATTERS

Corporate Governance Guidelines

The Board believes that sound governance practices and policies provide an important framework to assist it in fulfilling its duty to unitholders. Our Corporate Governance Guidelines cover the following principal subjects:

The Corporate Governance Guidelines are available on our website at www.blackstoneminerals.com under the “Corporate Governance” subsection of the “Investors” section. The Corporate Governance Guidelines will be reviewed periodically and as necessary by our Nominating and Governance Committee, and any proposed additions to or amendments of the Corporate Governance Guidelines will be presented to the Board for its approval.

The NYSE has adopted rules that require listed companies to adopt governance guidelines covering certain matters. We believe that the Corporate Governance Guidelines comply with the NYSE rules.

Board Leadership Structure

The Board’s leadership structure does not separate the Chief Executive Officer and Chairman of the Board positions. The Board retains the authority to modify this structure as and when appropriate, and it is possible that the Board may decide to separate the Chief Executive Officer and Chairman of the Board positions in the future.

The Board believes that there is no single, generally accepted approach to providing Board leadership and that each of the possible leadership structures for a board of directors must be considered in the context of the individuals involved and the specific circumstances facing a company as the right leadership structure may vary as circumstances change. The Board currently is of the view that it is in our best interest for the Chief Executive Officer to also serve as the Board’s Chairman. Mr. Carter serves as our Chief Executive Officer as well as Chairman of the Board. As the director most familiar with our business and industry and most capable of effectively identifying strategic priorities, he is best positioned to lead the Board through reviews of key business and strategic issues.

Executive Sessions of Non-Management Directors

The Board holds regular executive sessions in which the non-management directors meet without any members of management present. The purpose of these executive sessions is to promote open and candid discussion among the non-management directors. The director who presides at these meetings, the Lead Director, is elected by the Board and serves for a two-year term. Carin M. Barth currently serves as Lead Director and was initially elected in 2020. The Lead Director is responsible for preparing an agenda for the meetings of the

13

non-management directors in executive session. Currently, all the non-management directors of the Board are independent under the listing requirements of the NYSE.

Risk Oversight Procedures

The Board, as a whole, oversees our assessment of major risks and the measures taken to manage such risks. For example, the Board:

The Audit Committee is responsible for overseeing and discussing with management our guidelines and policies with respect to risk assessment and risk management, including our major financial risk exposures and the steps management has taken to monitor and control such exposures as well as the risks associated with our hedging strategy. The Compensation Committee is responsible for reviewing our incentive compensation arrangements to determine whether they encourage excessive risk-taking. It also reviews and discusses the relationship between risk management policies and practices and compensation and evaluates compensation policies and practices that could mitigate any such risk. The Board does not consider its role in oversight of our risk management function to be relevant to its choice of leadership structure.

Director Independence

The Board has determined that Ms. Barth, Mr. DeWalch, Mr. Kyle, Mr. Linn, Mr. Longmaid, Mr. Mathis, Mr. Randall, Mr. Stuart, and Mr. Whitehead are independent as defined by the rules of the NYSE.

Committees of the Board

The Board has the following standing committees: Audit Committee, Compensation Committee, and Nominating and Governance Committee. The Board will appoint a conflicts committee as necessary. The Audit Committee, the Compensation Committee, and the Nominating and Governance Committee each have a written charter approved by the Board. Each of these written charters is available on our website at

14

www.blackstoneminerals.com under the “Corporate Governance” subsection of the “Investors” section. Summaries of the functions performed by and the membership of each committee of the Board are set forth below.

Audit Committee

We maintain an audit committee of four members, and all its members meet the independence and experience standards established by the NYSE and Rule 10A-3 promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Ms. Barth and Messrs. Kyle, Randall and Whitehead currently sit on the Audit Committee, with Ms. Barth acting as the Committee Chair. The Board has also determined that Ms. Barth qualifies as an “audit committee financial expert,” as such term is defined under Securities and Exchange Commission (“SEC”) rules.

The Audit Committee assists the Board in its oversight of (i) the integrity of our financial statements, (ii) our compliance with legal and regulatory requirements, (iii) qualifications and independence of our independent registered public accounting firm, and (iv) performance of our internal audit function and independent registered public accounting firm. The Audit Committee has the sole authority to retain and terminate our independent registered public accounting firm, approve all auditing services and related fees and the terms thereof performed by our independent registered public accounting firm, and 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 is given unrestricted access to the Audit Committee and our management, as necessary.

Compensation Committee

Because we are a limited partnership, we are not required by the rules of the NYSE to have a compensation committee or a compensation committee composed entirely of independent directors. However, we have opted to maintain a compensation committee, and all of its members meet the independence standards established by the NYSE. Messrs. Linn, Longmaid, and Stuart currently sit on the Compensation Committee, with Mr. Stuart acting as the Committee Chair.

The Compensation Committee reviews and determines the compensation for the executive officers of the General Partner and reviews and makes recommendations to the Board regarding director compensation. The Compensation Committee also administers our incentive compensation and equity-based benefit plans.

15

The Compensation Committee is delegated all of its authority, as may be required or advisable to fulfill its purposes, by the Board. The Compensation Committee may delegate to any subcommittee it may form, the responsibility and authority for any particular matter, as it deems appropriate from time to time under the circumstances. Meetings may, at the discretion of the Compensation Committee, include members of management, other members of the Board, consultants or advisors, and such other persons as the Compensation Committee believes to be necessary or appropriate. The Compensation Committee will consult with our Chief Executive Officer when evaluating the performance of, and setting the compensation for, our executive officers other than the Chief Executive Officer.

The Compensation Committee may, in its sole discretion, retain and determine funding for legal counsel, compensation consultants, as well as other experts and advisors (collectively, “Committee Advisors”), including the authority to retain, approve the fees payable to, amend the engagement with and terminate any Committee Advisor, as it deems necessary or appropriate to fulfill its responsibilities. In 2023, the Compensation Committee engaged Frederick W. Cook & Co., Inc. (“FW Cook”) directly as its independent compensation consultant to assist the Committee with its responsibilities related to our executive officer and director compensation programs. A representative of FW Cook attends Compensation Committee meetings, as requested, and communicates with the Chair of the Compensation Committee between meetings. However, the Compensation Committee makes all decisions regarding the compensation of our executive officers and directors. FW Cook reports directly to the Compensation Committee and all work conducted by FW Cook for us is on behalf of the Compensation Committee.

The Compensation Committee regularly reviews the services provided by its outside consultant and believes that FW Cook is independent under applicable SEC rules in providing executive compensation consulting services. In making this determination, the Committee noted that during fiscal 2023:

The Compensation Committee periodically monitors the independence of FW Cook.

Nominating & Governance Committee

Because we are a limited partnership, we are not required by the rules of the NYSE to have a nominating and governance committee or a nominating and governance committee composed entirely of independent directors. However, we have opted to maintain a nominating and governance committee, and all its members meet the independence standards established by the NYSE. Messrs. DeWalch, Mathis, and Randall currently sit on the Nominating and Governance Committee, with Mr. Mathis acting as the Committee Chair.

The Nominating and Governance Committee identifies individuals qualified to serve on the Board and recommends director nominees for each annual meeting of limited partners or for appointment to fill vacancies, oversees our governance policies, including ESG policies, and oversees the evaluation of the Board and its committees.

16

Conflicts Committee

At least one independent member of the Board is required, by NYSE rules, to serve on a conflicts committee, as necessary, to review specific matters that the Board believes may involve conflicts of interest. The conflicts committee determines if the resolution of the conflict of interest is, in its subjective belief, not adverse to our interest. The members of the conflicts committee may not be officers or employees of the General Partner or directors, officers, or employees of its affiliates and must meet the independence standards established by NYSE and the Exchange Act rules to serve on an audit committee of a board of directors, along with the requirements in the Partnership Agreement. Any matters approved by the conflicts committee will be conclusively deemed to be approved by us and all our unitholders and not a breach by the General Partner of any duties or contractual obligations it may owe us or our unitholders.

Board and Committee Meeting Attendance

During the 2023 fiscal year, the Board held 7 regularly scheduled and special meetings of the full Board; the Audit Committee held 10 meetings; the Compensation Committee held 3 meetings; and the Nominating and Governance Committee held 4 meetings. All incumbent directors attended at least 75% of the aggregate number of meetings of the Board and committees of the Board on which they served.

Director Attendance at Annual Meetings of Limited Partners

Directors are encouraged, but not required, to attend the annual meetings of limited partners. All incumbent directors attended the Partnership’s 2023 annual meeting.

Director Nominations

Nominations of persons for election to the Board may be made at an annual meeting of the limited partners or, provided that the Board or unitholders have determined that directors will be elected at such a meeting, a special meeting of the limited partners, in any such case only pursuant to the General Partner’s notice of meeting (or any supplement thereto), (a) by or at the direction of the Board or any committee thereof, or (b) by any unitholder or group of unitholders who (1) is entitled to vote at the meeting, (2) complies with the notice procedures set forth in the Partnership Agreement, and (3) either individually or as a group hold units representing at least 10% of the outstanding units (measured on a fully diluted basis and treating the preferred units on an as-converted basis) both at the time of giving notice of such nomination and at the meeting. In addition, unitholders who intend to solicit proxies in support for director nominees other than the Partnership’s nominees must include the additional information required by Rule 14a-19(b) under the Exchange Act.

The Board believes that all directors must possess a considerable amount of management experience (such as experience as an executive), a solid financial background, and oil and gas related business or investment experience. The Nominating and Governance Committee is responsible for establishing criteria for the selection of new Board members and identifying (after taking into account all factors the Committee considers appropriate), evaluating, and recommending candidates to the Board for prospective Board membership. The Committee also considers matters relating to the retirement of Board members, including term limits or age limits, attendance at Board and committee meetings, conflicts of interest, and other relevant factors. The Nominating and Governance Committee does not have a formal policy with respect to diversity.

Majority Voting Policy

We have adopted a Majority Voting Policy, which provides that any incumbent nominee for director in an uncontested election (i.e., an election where the only nominees are those recommended by the Board) who receives a greater number of votes “withheld” from his or her election than votes “for” such election (a “Majority Withheld Vote”) shall promptly, but in any case, no later than five (5) business days following the certification of

17

the unitholder vote, tender his or her resignation for consideration by the Nominating and Governance Committee.

The Nominating and Governance Committee will promptly consider the tendered resignation and, as soon as reasonably practicable following the date of the Nominating and Governance Committee’s receipt of such resignation, but in any case, no later than 45 calendar days following certification of the unitholder vote, will recommend to the Board whether to accept the tendered resignation or to take some other action, such as rejecting the tendered resignation and addressing the apparent underlying causes of the Majority Withheld Vote. In making this recommendation, the Nominating and Governance Committee will consider all factors deemed relevant by its members, including the underlying reasons why unitholders “withheld” votes for the director (if ascertainable), the length of service and qualifications of the director whose resignation has been tendered, the director’s contributions to the Partnership, whether by accepting such resignation we will no longer be in compliance with any applicable law, rule, regulation, or governing document, and whether or not accepting the resignation is in the best interests of us and our unitholders.

The Board will promptly act on the Nominating and Governance Committee’s recommendation, but in any case, no later than 120 days following the certification of the unitholder vote. In consideration of the Nominating and Governance Committee recommendation, the Board will consider the factors considered by the Nominating and Governance Committee and such additional information and factors the Board deems relevant. We will promptly publicly disclose the Board’s decision and process in a periodic or current report filed with or furnished to the SEC.

Any director who, in accordance with the Majority Voting Policy, tenders his or her resignation, will not participate in the Nominating and Governance Committee recommendation or Board consideration regarding whether or not to accept the tendered resignation. However, such director shall remain active and engaged in all other Nominating and Governance Committee and Board activities, deliberations, and decisions during this Nominating and Governance Committee and Board process.

If a majority of the members of the Nominating and Governance Committee received a Majority Withheld Vote at the same election, then the independent directors who are on the Board and who did not receive a Majority Withheld Vote will act as the Board for the purpose of considering the tendered resignations and will decide whether to accept or reject them.

Communication with the Board

A holder of our units or other interested party who wishes to communicate with the directors of the General Partner may do so by sending communications to the Board, any committee of the Board, the Lead Director, the Chairman of the Board, or any other director by telephone at (713) 445-3200, or in writing to 1001 Fannin Street, Suite 2020, Houston, Texas, 77002 by marking the envelope containing each communication as “Unitholder Communication with Directors” and clearly identifying the intended recipient(s) of the communication. Communications will be relayed to the intended recipient of the Board except in instances where it is deemed unnecessary or inappropriate to do so pursuant to our Corporate Governance Guidelines, which are available on our website at www.blackstoneminerals.com in the “Corporate Governance” subsection under the “Investors” section. Any communications withheld under those guidelines will nonetheless be retained and available for any director who wishes to review them.

Code of Ethics

We have a Code of Business Conduct and Ethics that applies to our directors, officers, and employees as well as a Financial Code of Ethics that applies to our Chief Executive Officer, Chief Financial Officer, Chief Accounting Officer, and the other senior financial officers, each as required by NYSE and SEC rules. Each of the foregoing is available on our website at www.blackstoneminerals.com in the “Corporate Governance” subsection

18

of the “Investors” section. We will provide copies, free of charge, of any of the foregoing upon receipt of a written request to Investor Relations at Black Stone Minerals, L.P., 1001 Fannin Street, Suite 2020, Houston, Texas 77002. We intend to disclose amendments to and waivers, if any, from our Code of Business Conduct and Ethics and Financial Code of Ethics, as required, on our website, www.blackstoneminerals.com, promptly following the date of any such amendment or waiver.

Environmental, Social, and Governance Matters

We are committed to maintaining high standards in the stewardship of our assets, our social responsibilities as they relate to our hiring and employment practices, and our governance policies. Our Board has appointed Ms. Barth and Mr. Linn to an ESG Task Force that reports to our Nominating & Governance Committee. The ESG Task Force works with management to study the applicability of ESG frameworks to the minerals industry, to refine our ESG policies accordingly, and to recommend and review the publication of meaningful disclosure that is relevant to our investors.

Procedures for Review, Approval, and Ratification of Transactions with Related Persons

Under our Code of Business Conduct and Ethics, a director or officer is expected to bring to the attention of the General Counsel any conflict or potential conflict of interest that may arise between the director or officer or any affiliate of the director or officer, including a member of such person’s immediate family, on the one hand, and us or the General Partner on the other. The resolution of any conflict or potential conflict should, at the discretion of the Board and in light of the circumstances, taking in account the requirements of the NYSE with respect to related party transactions, be determined by a majority of the disinterested directors.

Certain Relationships and Related Party Transactions

We employ Fowler Carter, the son of Mr. Carter, Chairman, Chief Executive Officer and President of the General Partner, as Vice President, Business Development, and he received total compensation from us of approximately $322,162 during the year ended December 31, 2023. We also employ Stephen Fox, the son-in-law of Mr. Carter, as Land Manager, Gulf Coast, and he received total compensation from us of approximately $320,340 during the year ended December 31, 2023. We also employ Taylor DeWalch, the son of Mr. DeWalch, Director of the General Partner, as Vice President, Corporate Strategy & Development, and he received total compensation from us of approximately $468,439 during the year ended December 31, 2023.

Insider Trading Policy

We have an insider trading policy, which prohibits directors, officers, employees, and consultants from engaging in hedging or monetization transactions, whether direct or indirect, involving our securities, regardless of whether such persons are in possession of material, non-public information. Transactions involving Partnership-based derivative securities, including options, warrants, unit appreciation rights, convertible notes, or similar rights whose value is derived from the value of an equity security, are also prohibited. This policy does not restrict holding, exercising, or settling awards such as options, restricted units, or other derivative securities granted under a Partnership equity incentive plan.

EXECUTIVE COMPENSATION AND OTHER INFORMATION

COMPENSATION DISCUSSION AND ANALYSIS

This Compensation Discussion and Analysis (“CD&A”) describes the rationale and policies for the compensation of our named executive officers (“Named Executive Officers” or “NEOs”) for our fiscal year ending December 31, 2023 (the “2023 Fiscal Year”). Our Named Executive Officers for the 2023 Fiscal Year were:

This CD&A is intended to provide context for the tabular disclosure provided in the executive compensation tables below and to provide investors with the material information necessary to understanding our executive compensation program.

Pay and Partnership Performance Alignment

Our CEO’s compensation is directly aligned with the interests of our unitholders. As shown in the table below, our CEO’s reported compensation has historically adjusted at a similar rate as our total unitholder return, but remained flat or decreased in 2022 and 2023 despite a positive total unitholder return for those years.

“CEO Reported Pay” includes base salary, short-term incentive bonus actually earned, and the grant date fair value of long-term incentive awards granted in the applicable year, as reported in the summary compensation tables (“SCT”) in the Partnership’s proxy statements.

Compensation Best Practices

We use traditional compensation elements of base salary, annual and long-term incentives, and employee benefits to deliver an attractive and competitive compensation program. We benchmark both compensation and Partnership performance in evaluating the appropriateness of pay. All executive pay programs are administered by an independent Compensation Committee, with the assistance of an independent compensation consultant. The Compensation Committee engages in an annual review of the Partnership’s compensation program, which allows us to adjust our position based on market conditions and our business strategy to provide continual

20

alignment between our compensation philosophy and corporate objectives. Highlights of our executive compensation program include the following:

Compensation Strategy (Objectives of our Executive Compensation Program)

We design our executive compensation program to support our strategic goal of paying for performance and to motivate and reward executives for both short-term and long-term performance. The Partnership’s executive compensation program is structured to focus on the following key objectives:

21

Peer Group (Demonstrating the Competitive Market for Pay)

The Compensation Committee utilizes a comparative group of industry companies (the “Peer Group”) to evaluate the competitiveness of our executive compensation program. The Peer Group represents organizations of comparable size and complexity of operations. Further, the Peer Group represents those organizations with which we compete for talent. The Compensation Committee reviews the Peer Group annually to ensure continued appropriateness for benchmarking purposes. For the 2023 Fiscal Year, the Peer Group consisted of companies selected for comparative size, complexity, revenue, EBITDA, and market capitalization.

The Compensation Committee assesses our compensation elements using compiled Peer Group data and national compensation survey data to establish market consensus information (“Competitive Market Data”). The Peer Group used for 2023 compensation benchmarking consisted of the following companies:

Adjustments are made to our peer group throughout the year in order to reflect certain transactional activities of our peers, such as being merged out of existence or filing for bankruptcy.

Key Components of our Compensation Program and Compensation Mix

Our executive compensation program is a traditional structure that has been customized to align with the Partnership’s business and organizational objectives. We annually evaluate the various components of our compensation program relative to the competitive market. Our compensation and benefit programs for the 2023 Fiscal Year consisted of the following key components, which are described in greater detail below:

In allocating compensation among the various components, we emphasize performance-based, at-risk compensation while also providing competitive levels of fixed compensation. Long-term incentives constitute the largest portion of total compensation and provide an important connection to common unitholder interests. We do not target a specific percentage for each element of compensation relative to total compensation. We evaluate each element against the competitive market within the parameters of our compensation strategy. Therefore, the relative weighting of each element of our total pay mix may change over time as the competitive market moves or other market conditions change.

22

The charts below show the target compensation mix for Mr. Carter, our Chief Executive Officer, and the average target compensation mix of the other NEOs for the 2023 Fiscal Year. For this purpose, all incentive awards are included at target levels of performance (and for LTI Performance Units (as defined below), multiplying such target units by the closing price of our common units on the grant date).

23

ELEMENTS OF THE EXECUTIVE COMPENSATION PROGRAM

Base Salary

Each NEO’s base salary is a fixed component of compensation and does not vary depending on the level of performance achieved. Base salaries are determined for each NEO based on position and responsibility and are generally set at levels deemed necessary to attract and retain individuals with superior talent commensurate with their relative expertise and experience. We review the base salaries for each NEO annually as well as at the time of any promotion or significant change in job responsibilities, and in connection with each review, we consider individual and company performance over the course of that year. The Compensation Committee approved increases to base salaries in 2023 for certain NEOs to align their base salaries closer to the median for their positions compared to the Competitive Market Data. The Compensation Committee increased Mr. Kiefer’s base salary in connection with his promotion to Interim CFO. Mr. Wood did not receive a base salary increase in 2023. Base salaries for our NEOs for 2022 -2023 are set forth in the table below:

Short-Term Incentive Bonuses

Our performance-based short-term incentive bonus (“STI Bonus”) granted under the LTIP is based upon our pay-for-performance philosophy. The STI Bonus provides our NEOs with an incentive in the form of an annual bonus to achieve our overall business goals. These awards are payable based on the achievement of annual financial objectives measured against our internal operating plan established at the beginning of each fiscal year. Final payouts are subject to reduction or increase by the Compensation Committee for individual and team performance during the performance period.

Annual STI Bonus targets are measured as a percentage of each NEO’s base salary and are reviewed and confirmed annually by the Compensation Committee. Due to the transition in the Chief Financial Officer role in 2023, Mr. Wood was not eligible for an STI Bonus for 2023, and Mr. Kiefer’s target STI Bonus was increased to 100% upon his appointment as Interim CFO. Otherwise, no changes were made to any of our NEO’s annual STI Bonus target percentages for the 2023 Fiscal Year. The table below provides STI Bonus targets as a percentage of base salary for each of our NEOs for the 2023 Fiscal Year.

Payouts can range from 0% to 200% of the established percentage of salary, with a payout of 50% if threshold performance is achieved, 100% if target performance is achieved, and 200% if maximum performance is achieved.

24

2023 STI Performance Results

The STI Bonuses for the 2023 Fiscal Year were equal to the product of each NEO’s (i) target bonus and (ii) our adjusted EBITDAX Payout Factor, which is based on our adjusted EBITDAX achievement level, but further adjusted as described below. For the 2023 Fiscal Year, the adjusted EBITDAX target established at the beginning of the performance period was $474.526 million.

For purposes of calculating the STI Bonus, adjusted EBITDAX was calculated as the ratio of our actual adjusted EBITDAX for the applicable year to our budgeted adjusted EBITDAX for such year, as adjusted by an Adjusted EBITDAX Payout Factor that emphasizes the effect of under-or over-achievement, with linear interpolations between the target and either the threshold or maximum, as outlined below:

Actual adjusted EBITDAX for the 2023 Fiscal Year was $474.528 million. We achieved an adjusted EBITDAX payout factor of slightly more than 100% of target.

The STI Bonus achievement resulted in payments to participants as reflected below:

Long-Term Incentives

Our long-term incentive program is designed to align the interests of executive officers with unitholders and reward executives for achievement of long-term goals. Long-term incentives play an important role in the retention of executives and provide executives an opportunity to acquire equity ownership in the Partnership. For these reasons, we place more emphasis on long-term incentive compensation than any other compensation element. Long-term equity incentive awards are provided under the Black Stone Minerals, L.P. Long-Term Incentive Plan (“LTIP”).

25

The Compensation Committee annually reviews and determines the allocation between the long-term incentive vehicles based on Competitive Market Data, as well as input from senior management regarding our key business drivers. For the 2023 Fiscal Year, the long-term incentive program consisted of annual grants of an equal combination of performance-based unit awards and time-based restricted unit awards. This reflects the Compensation Committee’s goal of aligning the interests of our NEOs with our unitholders. In February 2023, the Compensation Committee approved target annual long-term incentive award increases of 5% for each of Messrs. Carter and Putman and Ms. Smajstrla; and 50% for Ms. Clark to align their target annual long-term incentive awards with Competitive Market Data.

LTI Performance Units

One-half of the target value of annual long-term incentive awards granted to our NEOs for the 2023 Fiscal Year consisted of long- term performance-based phantom units (“LTI Performance Units”) granted under the LTIP. The Compensation Committee grants performance-based awards to drive our performance towards achievement of established goals over a three-year performance period. The performance targets are intended to encourage long-term growth and bolster the health of the Partnership’s assets. The target LTI Performance Units granted to each NEO are reflected in the following table:

The annual grants of LTI Performance Units awarded during the 2023 Fiscal Year are measured based on the average performance percentage attained over the performance period beginning January 1, 2023 and ending December 31, 2025. The percent of these target LTI Performance Units that will become earned upon the attainment of average performance percentage will be determined using linear interpolation in accordance with the following table:

The average performance percentage is determined by finding the mean of the “production performance percentage” and the “reserve performance percentage” for each of the three years in the performance period. The “production performance percentage” reflects the attainment of per-unit production levels as a percentage of the budgeted per-unit production levels (as determined by the Board of the General Partner) for the applicable year. The “reserve performance percentage” reflects the attainment of per-unit proved reserve levels as a percent of the budgeted per-unit proved reserve levels (as determined by the Board) for the applicable year. For the 2023 Fiscal Year, the “reserve performance percentage” was achieved at 96.69% of target and the “production performance percentage” was achieved at 105.47%, resulting in an “average performance percentage” of 101.08% of target; however, the actual performance achieved will not be determined until the completion of the three-year performance period.

LTI Restricted Units

One-half of the target value of annual long-term incentive awards granted to our NEOs for the 2023 Fiscal Year consisted of restricted unit awards (“LTI Restricted Units”). The Compensation Committee grants these time-

26

based awards to encourage and promote retention of key employees. The LTI Restricted Units granted to all NEOs on February 1, 2023, vest in one-third increments on each of January 7, 2024, January 7, 2025, and January 7, 2026. The LTI Restricted Units granted to each NEO are reflected in the following table:

Settlement of 2021 LTI Performance Units

Vesting and payout of the 2021 LTI Performance Units was assessed by the Compensation Committee in February 2024. The following table summarizes the performance as a percentage of target for the 2021 LTI Performance Units based on production and reserve performance over the three-year period ending December 31, 2023.

The following table summarizes the payouts for the 2021 LTI Performance Units based on production and reserve performance over the three-year period ending December 31, 2023.

Post-Employment and Change in Control Benefits

Each of the NEOs other than Ms. Smajstrla is party to a severance agreement that provides for severance payments and benefits upon certain terminations of employment, including enhanced benefits upon certain terminations of employment following a change in control. These severance agreements are intended to provide protections to the NEOs in the event of certain involuntary terminations, and they assist in recruiting and

27

retaining high performing talent. Additionally, these agreements provide us with an opportunity to obtain non-competes and other restrictive covenants, providing protection to the Partnership in the event of the termination of an NEO’s employment. Ms. Smajstrla is not party to a severance agreement because she is a vice-president-level executive officer, unlike the remainder of the NEOs who are Senior Vice Presidents or more senior executives of the Company.

In connection with Mr. Wood’s departure on February 28, 2023, the Company entered into a Separation Agreement with Mr. Wood that provided for payments consistent with his existing severance agreement and award agreements. The Compensation Committee and Board determined that these amounts were appropriate because (a) Mr. Wood’s departure was a qualifying termination under his existing severance agreement and award agreements, and (b) moreover, the payments recognized Mr. Wood’s integral role in the Company’s success as a public company, his support in navigating the Company through difficult times, including the COVID-19 pandemic and the accompanying downturn in the commodity markets, and his contributions to the Company, leaving it in one of the strongest financial positions in its history.

For a description of the terms of the severance agreements and arrangements with each of the NEOs, please see the section below entitled “Potential Payments Upon Termination or a Change in Control.”

Other Benefits

We currently maintain a 401(k) Plan, which permits all eligible employees, including the NEOs, to make voluntary pre-tax or after-tax (Roth) contributions to the plan. In addition, we are permitted to make discretionary matching contributions under the plan. In 2023, the Partnership’s matching contribution rate was 100% of the first 5% of eligible compensation deferred by an employee, up to the annual allowable U.S. Internal Revenue Code limits. Matching contributions are subject to a graded vesting schedule, with 33% vested after one year, 66% vested after two years, and 100% vested after the initial three years of employment with us. Following three years of employment, future Partnership matching contributions vest immediately. All contributions under the plan are subject to certain annual dollar limitations, which are periodically adjusted for changes in the cost of living.

We also provide health and welfare benefits to our NEOs on the same terms as generally offered to our employees. In addition, we pay the costs associated with Mr. Carter’s club memberships. The aggregate cost of these memberships is less than $10,000 per year, and as a result, these amounts are not reflected in the “Summary Compensation Table” below.

Say-on-Pay and Say-on-Frequency

Last year, our limited partners overwhelmingly approved, on an advisory basis, the compensation programs for our NEOs. Advisory votes in favor of these programs were cast by over 98% of the votes cast by unitholders at the 2023 Annual Meeting. At our annual meeting held in 2018, our unitholders voted in favor of holding advisory “Say-on-Pay” votes on an annual basis, which was the frequency recommended by the Board of the General Partner. As described in Proposal 4 below, our unitholders will have an opportunity at the Annual Meeting to participate in an advisory vote on the frequency of future advisory votes to approve our executive compensation.

Consistent with this say-on-frequency vote, we hold “Say-on-Pay” votes on an annual basis, as we believe that annual “Say-on-Pay” votes provide the Partnership with more direct and immediate feedback on our compensation disclosures and enables the Board and the Compensation Committee to determine current limited partner sentiment. The Board and the Compensation Committee took the results of the last “Say-on-Pay” vote into account when evaluating the compensation program for our Named Executive Officers in 2023. Based in part on the level of support from our limited partners, the Compensation Committee elected not to make any material changes to the compensation programs for our Named Executive Officers during 2023. We appreciate our limited partners’ continuing annual feedback regarding our NEO pay practices. As discussed in more detail in

28

Proposal 3 below, the Board has recommended that unitholders vote, on a non-binding advisory basis, to approve the 2023 executive compensation program as described below.

Process and Procedures for Determining Executive Compensation

Our executive compensation program is overseen by the Compensation Committee. The Board of the General Partner discusses compensation issues during full board meetings, but the Compensation Committee has ultimate responsibility for making decisions relating to the compensation of our NEOs. Our Compensation Committee comprises three members of the Board, with Alexander D. Stuart serving as the chair and Michael C. Linn and John H. Longmaid serving as members for 2023. All members of the Compensation Committee meet the independence standards established by the NYSE. The Compensation Committee Charter provides the Compensation Committee with authority to, among other things:

Although the above authority has been delegated to the Compensation Committee pursuant to the Compensation Committee Charter, the Board retains full responsibility with respect to continuing oversight of the Compensation Committee and its actions. For more detailed information regarding the Compensation Committee, the current Compensation Committee Charter is posted under the “Corporate Governance” subsection of the “Investors” section of our website at www.blackstoneminerals.com.

Our Chief Executive Officer reviews compensation for all our NEOs other than himself and makes compensation recommendations to the Compensation Committee. The Compensation Committee also receives information and advice from its independent compensation consultant as well as from our human resources department and management to assist in compensation determinations. The Compensation Committee typically reviews the components of our executive officer compensation program on an annual basis and approves adjustments as it deems appropriate. The Compensation Committee then evaluates the Chief Executive Officer’s recommendations and conducts its own independent review and evaluation of the Chief Executive Officer’s compensation and makes a final determination with respect to compensation for all NEOs based on several factors, including individual performance, business results, and Competitive Market Data. The Compensation Committee makes all final compensation decisions for our NEOs by exercising its discretion in accepting, modifying, or rejecting any management recommendations.

The Compensation Committee generally approves any changes to base salary levels, bonus opportunities, and other annual compensation components on or before February 28 of each fiscal year, with such changes traditionally becoming effective as of January 1 of such fiscal year.

Role of the Independent Compensation Consultant

The Compensation Committee has engaged FW Cook to serve as its independent compensation consultant. The independent compensation consultant reports to and acts at the direction of the Compensation Committee. FW

29

Cook provides no services for management or the Compensation Committee that are unrelated to the duties and responsibilities of the Compensation Committee. At the request of the Compensation Committee, FW Cook has undertaken comprehensive market reviews annually, which have been utilized by the Compensation Committee when making its recommendations for the Partnership’s compensation programs. The Compensation Committee annually reviews FW Cook’s independence under NYSE rules and has determined that FW Cook is independent.

Role of the Executive Officers

Executive compensation decisions are typically made on an annual basis by the Compensation Committee. Our Chief Executive Officer/President, General Counsel, and occasionally other executive officers attend Compensation Committee meetings and assist in the process and provide input regarding the compensation of the NEOs, other than themselves. During executive sessions of the Compensation Committee, the Chief Executive Officer, General Counsel, and any other executive officers are excused. Although the Compensation Committee considers the input from the Chief Executive Officer and General Counsel, the Compensation Committee makes all final determinations regarding executive compensation.

OTHER COMPENSATION ITEMS

Tax and Accounting Implications

We account for equity compensation expenses under the rules of Financial Accounting Standards Board Accounting Standards Codification Topic 718 (“FASB ASC Topic 718”), which requires us to estimate and record an expense for each award of equity compensation over the vesting period of the award. Accounting rules also require us to record cash compensation as an expense at the time the obligation is accrued. Section 162(m) of the U.S. Internal Revenue Code (“Section 162(m)”) generally limits the deductibility by a corporation of compensation that exceeds $1,000,000 paid to certain executive officers. Because we are a limited partnership, Section 162(m) generally does not apply to compensation paid to our NEOs for services provided to us. Accordingly, the Compensation Committee does not consider its impact in determining compensation levels. Section 409A of the U.S. Internal Revenue Code (“Section 409A”) requires that “nonqualified deferred compensation” be deferred and paid under plans or arrangements that satisfy the requirements of the statute with respect to the timing of deferral elections, timing of payments, and certain other matters. Failure to satisfy these requirements can expose employees and other service providers to accelerated income tax liabilities and penalty taxes and interest on their vested compensation under such plans. Accordingly, as a general matter, it is the Partnership’s intention to design and administer our compensation and benefits plans and arrangements for all employees and other service providers, including the executive officers, so that those arrangements are either exempt from, or satisfy the requirements of, Section 409A.

Clawback Policy

We maintain the Black Stone Minerals, L.P. Incentive Compensation Recoupment Policy (the “Clawback Policy”), which we amended and restated in October 2023 in connection with the new SEC final rules and NYSE listing requirements governing clawbacks. In the event of a required restatement of the Partnership’s financial statements due to material non-compliance with any financial reporting requirement, the Clawback Policy provides the Board of the General Partner with authority to require the reimbursement or forfeiture of unvested, performance-based equity granted pursuant to the LTIP.

Unit Ownership and Retention Guidelines

We maintain unit ownership and retention guidelines. These guidelines require officers and non-employee directors to maintain a minimum level of unit ownership equal to the following:

Officers and non-employee directors appointed since the IPO must comply with the ownership guidelines within five years of their appointment to a position subject to the guidelines. Until such unit ownership is achieved, we encourage officers and non-employee directors to retain at least 50% of the “net” units obtained through awards granted pursuant to the LTIP. The Compensation Committee reviews current unit ownership annually. As of December 31, 2023, all our current officers and non-employee directors subject to these guidelines were in compliance with the applicable requirements of our unit ownership guidelines or on track to achieve compliance within the required time period. However, compliance is subject to the Partnership’s unit price performance and is thus subject to change.

Risk Assessment

The Compensation Committee has reviewed our compensation policies as generally applicable to our employees and believes that our policies do not encourage excessive and unnecessary risk-taking, and that the level of risk

31

that they do encourage is not reasonably likely to have a material adverse effect on us. Management reviews the risks arising from our compensation policies and practices. The management team reviewed and discussed the design features, characteristics, performance metrics at the Partnership and segment levels and approval mechanisms of total compensation for all employees, including salaries, incentive plans, and equity-based compensation awards, to determine whether any of these policies or programs could create risks that are reasonably likely to have a material adverse effect on us.

Our compensation philosophy and culture support the use of base salary, performance-based compensation, and retirement plans that are generally uniform in design and operation throughout our organization and with all levels of employees. These compensation policies and practices are centrally designed and administered, and they are substantially identical between our business divisions. In addition, the following specific factors, in particular, reduce the likelihood of excessive risk-taking:

In summary, although a significant portion of the compensation provided to Named Executive Officers is performance-based, we believe our compensation programs do not encourage excessive and unnecessary risk taking by executive officers (or other employees) because these programs are designed to encourage employees to remain focused on both our short- and long-term operational and financial goals. We set performance goals that we believe are reasonable in light of our past performance and market conditions. A portion of the performance-based, variable compensation we provide is made up of long-term incentives in the form of long-term restricted unit awards subject to time-based vesting conditions, which retains value even in a depressed market, so executives are less likely to take unreasonable risks. With respect to our annual performance-based incentives, assuming achievement of at least a threshold level of performance, payouts result in some compensation at levels below full target achievement.

COMPENSATION COMMITTEE REPORT

The Compensation Committee has reviewed and discussed our Compensation Discussion and Analysis with management. Based upon such review, the related discussion with management, and such other matters deemed relevant and appropriate by the Compensation Committee, the Compensation Committee has recommended to the Board of the General Partner that our Compensation Discussion and Analysis be included in the Partnership’s Annual Report on Form 10-K for the year ended December 31, 2023 and in this Proxy Statement.

Pension Benefits and Nonqualified Deferred Compensation

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

Potential Payments Upon Termination or a Change in Control

Each of our NEOs may be entitled to certain severance and other benefits upon a termination of employment under the terms of their respective award agreements and severance agreements, as described in further detail below. The description of the relevant terms of such award agreements and severance agreements set forth below does not purport to be a complete description of all of the provisions of any such agreements and is qualified in its entirety by reference to the forms of award agreements and severance agreements previously filed.

Severance Agreements

Messrs. Carter and Putman entered into severance agreements with an affiliate of the General Partner in connection with the IPO, and Messrs. Kiefer and Wood and Ms. Clark each entered into similar severance agreements in connection with their respective commencement of employment or promotion, that, among other things, provides for the payment of cash severance payments and benefits in the event the NEO’s employment is terminated under certain circumstances. Ms. Smajstrla is not party to a severance agreement.

Each applicable NEO’s severance agreement provides that if the NEO experiences a “qualifying termination,” then so long as the NEO executes (and does not revoke within any time provided to do so) a release in a form satisfactory to us within the applicable time period specified in the severance agreement, the NEO will receive the following severance payments and benefits: (a) a lump sum cash severance payment equal to the sum of:

38

(i) an amount equal to the Severance Multiple provided below multiplied by the sum of the NEO’s annualized base salary and target annual bonus as in effect on the Determination Date provided below (or, if such termination occurs within 24 months following a “change in control,” an amount equal to the CIC Severance Multiple provided below) multiplied by the sum of the NEO’s annualized base salary and target annual bonus as in effect on the Determination Date ; (ii) a pro rata portion of the NEO’s target bonus for the calendar year that includes the Determination Date ; and (iii) any earned but unpaid bonus for the calendar year preceding the calendar year that includes the date of such termination; and (b) monthly cash reimbursement for the amount the NEO pays for continuation coverage under our affiliates’ group health plans for up to 12 months following such termination (or, if such termination occurs within 24 months following a change in control, for up to 24 months following such termination).

Under each severance agreement:

The severance agreements also contain certain restrictive covenants pursuant to which our NEOs recognize an obligation to comply with, among other things, certain confidentiality covenants and covenants not to compete in

39

a defined market area with us or any of affiliates or solicit any of our affiliates’ employees, in each case, during the term of the agreement and for a period of one year (or, the case of Mr. Carter, two years) thereafter.

Smajstrla STI Bonus Award Letter

Ms. Smajstrla’s 2023 STI Bonus award letter provides that upon her termination of employment prior to December 31, 2023 without “cause,” due to her death or “disability,” or due to “good reason,” then so long as she executes (and does not revoke within any time provided to do so) a release in a form satisfactory to us within the applicable time period specified in the STI Bonus award letter she her estate, as applicable) shall receive a pro rata STI Bonus for the year of termination assuming achievement of target performance. Ms. Smajstrla’s STI Bonus award letter specifies that she must only remain employed through December 31, 2023, to receive her STI Bonus for the 2023 fiscal year. Therefore, upon her termination for any reason upon December 31, 2023, she shall be eligible to receive an STI Bonus based on actual performance. Because Ms. Smajstrla is not party to a severance agreement, she is not entitled to any other cash severance payments or benefits.

Under Ms. Smajstrla’s STI Bonus award letter:

LTI Award Agreements

Under each NEO’s LTI Performance Unit award agreements, if the NEO experiences a “qualifying termination” that is not within 24 months following a “change of control,” subject to the NEO’s execution and non-revocation of a release, the performance period shall be deemed to have ended as of the date of such termination and a pro rata portion of the NEO’s performance units will become earned based on actual performance through the date of such termination. If a NEO’s employment is terminated as a result of the NEO’s death or “disability” or if the “qualifying termination” occurs within 24 months following a “change of control,” the NEO’s performance units will become earned based on actual performance through the date of such termination and assuming target performance for the remainder of the performance period. In each case, the NEO will also be entitled to receive additional common units equal to the value of the cumulative amount of cash distributions that would have been paid to the NEO by us in respect of a common unit if the NEO had held a common unit during the period commencing on the date of grant of the performance units and ending on the date of termination of the NEO’s employment.

Under each NEO’s LTI Restricted Unit award agreements, if the NEO experiences a “qualifying termination,” subject to the NEO’s execution and non-revocation of a release, a pro rata portion of the NEO’s unvested common units will become vested as of such termination, so long as the NEO has remained continuously employed between the date of grant through the date of such termination of employment; provided that if such termination of employment occurs within 24 months following a “change of control” or such termination occurs

40

as a result of the NEO’s “disability” or death, all of the NEO’s unvested common units will become vested as of such termination.

Under each NEO’s Aspirational Award agreement, if the NEO experiences a “qualifying termination” or if the NEO’s employment is terminated as a result of the NEO’s “disability” or death, subject to the NEO’s execution and non-revocation of a release, a pro rata portion of the LTI Performance Units subject to the Aspirational Award shall remain outstanding and eligible to vest if the applicable performance goals are achieved as of the end of the performance period.

For purposes of the LTI award agreements for both the performance units and the restricted units described above, “change of control,” “disability” and “qualifying termination” generally have the same meanings provided above under the severance agreements.

The table below discloses the amount of compensation and/or other benefits due to the NEOs in the event of their termination of employment, assuming the termination occurred on December 31, 2023.

41

Wood Separation Agreement

Mr. Wood ceased service as our President, Chief Financial Officer, and Treasurer as of February 28, 2023. On March 2, 2023, Black Stone Natural Resources Management Company (the “Employer”) and the General Partner entered into a Separation Agreement and General Release of Claims (the “Wood Separation Agreement”) with Mr. Wood, substantially consistent with his then-existing severance agreement.

Pursuant to the Wood Separation Agreement, Mr. Wood received the following consideration in accordance with the terms of his severance agreement with the Employer and the applicable equity award agreements with the General Partner, contingent upon his continued compliance with the terms and conditions of his separation agreement:

42

Mr. Wood remains subject to the confidentiality, non-competition, non-solicitation and non-disparagement covenants set forth in his severance agreement; however, the non-competition covenant has been modified to limit certain restrictions so that those restrictions only prohibit affiliation with certain entities.

The table below quantifies the value of the payments and benefits received or to be received by Mr. Wood pursuant to the Wood Separation Agreement.

43

DIRECTOR COMPENSATION

Officers or employees of the General Partner or any of its affiliates who also serve as directors of the General Partner will not receive additional compensation for such service. Each director of the General Partner who is not an officer or employee of the General Partner or any of its affiliates receives the following cash compensation:

In addition to cash compensation, our non-employee directors receive annual equity-based compensation under the LTIP consisting of fully vested common units with an aggregate grant date value equal to approximately $200,000. Annual equity-based compensation is paid to our non-employee directors in a lump sum in arrears and is proportionately adjusted for partial years of service. Annual equity-based compensation awards are subject to the terms and conditions of the LTIP and the award agreements pursuant to which such awards are granted. In the year in which a new non-employee director is elected to the Board of the General Partner for the first time, such director receives a one-time initial award under the LTIP with a grant date value approximately equal to $100,000, subject to the terms and conditions of the LTIP and the award agreement pursuant to which such award is granted. Mr. Whitehead began service as a director of the General Partner on August 11, 2023 and received such a grant.

All retainers are paid in cash on a quarterly basis in arrears, subject to a non-employee director’s election to instead receive such retainers in the form of fully vested common units and are proportionately adjusted for partial years of service. Our non-employee directors do not receive any meeting fees, but each director is reimbursed for (i) travel and miscellaneous expenses to attend meetings and activities of the Board or its committees and (ii) travel and miscellaneous expenses related to participation in general education and orientation programs for directors.

CEO PAY RATIO

As required by Section 953(b) of the Dodd-Frank Wall Street Reform and Consumer Protection Act, and Item 402(u) of Regulation S-K, we are providing the following information about the relationship of the median annual total compensation of our employees (other than the Chief Executive Officer) and the annual total compensation of Thomas L. Carter, Jr., our Chief Executive Officer (our “CEO”).

For the 2023 fiscal year, our last completed fiscal year:

To identify the median of the annual total compensation of all our employees, as well as to determine the annual total compensation of our median employee and our CEO, we took the following steps:

With respect to the annual total compensation of our CEO, we used the amount reported in the “Total” column of our 2023 Summary Compensation Table included in this Proxy Statement and incorporated by reference under Item 11 of Part III of our Annual Report.
