IMPORTANT NOTICE REGARDING THE AVAILABILITY OF PROXY MATERIALS

FOR THE STOCKHOLDER MEETING TO BE HELD ON TUESDAY, JUNE 9, 2026

This Proxy Statement and our 2025 Annual Report to Stockholders are available at

http://www.proxyvote.com/

At the Annual Meeting, our stockholders will be asked:

We know of no other business that will be presented at the Annual Meeting. If any other matter properly comes before the stockholders for a vote at the Annual Meeting, however, the proxy holders named on the Company’s proxy card will vote your shares in accordance with their best judgment.

The Board of Directors (the “Board”) recommends that you vote your shares as indicated below. If you return a properly completed proxy card, or vote your shares by telephone or Internet, your shares of common stock will be voted on your behalf as you direct. If not otherwise specified, the shares of common stock represented by the proxies will be voted, and the Board recommends that you vote:

If any other matter properly comes before the stockholders for a vote at the Annual Meeting, the proxy holders named on the Company’s proxy card will vote your shares in accordance with their best judgment.

Why you received this proxy statement. You are viewing or have received these proxy materials because GCM’s Board is soliciting your proxy to vote your shares at the Annual Meeting. This proxy statement includes information that we are required to provide to you under the rules of the SEC and that is designed to assist you in voting your shares.

Notice of Internet Availability of Proxy Materials. As permitted by SEC rules, GCM is making this proxy statement and its 2025 Annual Report available to its stockholders electronically via the Internet. On or about April 24, 2026, we mailed to our stockholders a Notice of Internet Availability of Proxy Materials (the “Internet Notice”) containing instructions on how to access this proxy statement and our 2025 Annual Report and vote online. If you received an Internet Notice by mail, you will not receive a printed copy of the proxy materials in the mail unless you specifically request them. Instead, the Internet Notice instructs you on how to access and review all of the important information contained in the proxy statement and 2025 Annual Report. The Internet Notice also instructs you on how you may submit your proxy over the Internet. If you received an Internet Notice by mail and would like to receive a printed copy of our proxy materials, you should follow the instructions for requesting such materials contained on the Internet Notice.

Printed Copies of Our Proxy Materials. If you received printed copies of our proxy materials, then instructions regarding how you can vote are contained on the proxy card included in the materials.

Householding. The SEC’s rules permit us to deliver a single set of proxy materials to one address shared by two or more of our stockholders. This delivery method is referred to as “householding” and can result in significant cost savings. To take advantage of this opportunity, we have delivered only one set of proxy materials to multiple stockholders who share an address, unless we received contrary instructions from the impacted stockholders prior to the mailing date. We agree to deliver promptly, upon written or oral request, a separate copy of the proxy materials, as requested, to any stockholder at the shared address to which a single copy of those documents was delivered. If you prefer to receive separate copies of the proxy materials, contact Broadridge Financial Solutions, Inc. at 1-866-540-7095 or in writing at Broadridge, Householding Department, 51 Mercedes Way, Edgewood, New York 11717.

If you are currently a stockholder sharing an address with another stockholder and wish to receive only one copy of future proxy materials for your household, please contact Broadridge at the above phone number or address.

The Record Date for the Annual Meeting is April 10, 2026. You are entitled to vote at the Annual Meeting only if you were a stockholder of record at the close of business on that date, or if you hold a valid proxy for the Annual Meeting. Each outstanding share of Class A common stock is entitled to one vote per share and each outstanding share of Class C common stock is entitled to 1.258274552 votes per share for all matters before the Annual Meeting in accordance with the provisions of our Charter and the Stockholders Agreement. Holders of Class A common stock and Class C common stock vote together as a single class on any matter (including the proposals to be voted on at the Annual Meeting) that is submitted to a vote of our stockholders, unless otherwise required by law or our Charter. At the close of business on the Record Date, there were 59,418,170 shares of Class A common stock and 141,665,831 shares of Class C common stock outstanding and entitled to vote at the Annual Meeting, representing approximately 25% and 75% voting power of our common stock, respectively.

A record holder holds shares in his or her name. Shares held in “street name” means shares that are held in the name of a bank or broker on a person’s behalf.

Yes. If your shares are held by a bank or a brokerage firm, you are considered the “beneficial owner” of those shares held in “street name.” If your shares are held in street name, these proxy materials are being provided to you by your bank or brokerage firm, along with a voting instruction card if you received printed copies of our proxy materials. As the beneficial owner, you have the right to direct your bank or brokerage firm how to vote your shares, and the bank or brokerage firm is required to vote your shares in accordance with your instructions. See “How do I vote—Beneficial Owners of Shares Held in ‘Street Name”’ below for additional information.

A quorum must be present at the Annual Meeting for any business to be conducted. The presence at the Annual Meeting online or by proxy, of the holders of a majority in voting power of the common stock issued and outstanding and entitled to vote on the Record Date will constitute a quorum.

GCM has decided to hold the Annual Meeting entirely online this year. You may attend and participate in the Annual Meeting by visiting the following website: www.virtualshareholdermeeting.com/GCMG2026. To attend and participate in the Annual Meeting, you will need the 16-digit control number included on your proxy card or on the instructions that accompanied your proxy materials. If your shares are held in “street name,” you should contact your bank or broker to obtain your 16-digit control number or otherwise vote through the bank or broker. If you lose your 16-digit control number, you may join the Annual Meeting as a “Guest” but you will not be able to vote, ask questions or access the list of stockholders as of the Record Date. The meeting webcast will begin promptly at 1:00 p.m. Central time. We encourage you to access the meeting prior to the start time. Online check-in will begin at 12:45 p.m., Central time, and you should allow ample time for the check-in procedures.

If a quorum is not present at the scheduled time of the Annual Meeting, the Chairperson of the Annual Meeting is authorized by our Bylaws to adjourn the meeting, without the vote of stockholders.

It means that your shares are held in more than one account at the transfer agent and/or with banks or brokers. Please vote all of your shares. To ensure that all of your shares are voted, for each Internet Notice or set of proxy materials, please submit your proxy by phone, via the Internet, or, if you received printed copies of the proxy materials, by signing, dating and returning the enclosed proxy card in the enclosed envelope.

Stockholders of Record. If you are a stockholder of record, you may vote:

Internet and telephone voting facilities for stockholders of record will be available 24 hours a day and will close at 11:59 p.m., Eastern time, on June 8, 2026. To participate in the Annual Meeting, including to vote via the Internet or telephone, you will need the 16-digit control number included on your Internet Notice, on your proxy card or on the instructions that accompanied your proxy materials.

Whether or not you expect to attend the Annual Meeting online, we urge you to vote your shares as promptly as possible to ensure your representation and the presence of a quorum at the Annual Meeting. If you submit your proxy, you may still decide to attend the Annual Meeting and vote your shares electronically.

Beneficial Owners of Shares Held in “Street Name.” If your shares are held in “street name” through a bank or broker, you will receive instructions on how to vote from the bank or broker. You must follow their instructions in order for your shares to be voted. Internet and telephone voting also may be offered to stockholders owning shares through certain banks and brokers. If your shares are not registered in your own name and you would like to vote your shares online at the Annual Meeting, you should contact your bank or broker to obtain your 16-digit control number or otherwise vote through the bank or broker. If you lose your 16-digit control number, you may join the Annual Meeting as a “Guest” but you will not be able to vote, ask questions or access the list of stockholders as of the Record Date. You will need to obtain your own Internet access if you choose to attend the Annual Meeting online and/or vote over the Internet.

Yes.

If you are a registered stockholder, you may revoke your proxy and change your vote:

Your most recent proxy card or Internet or telephone proxy is the one that is counted. Your attendance at the Annual Meeting by itself will not revoke your proxy unless you give written notice of revocation to the Secretary before your proxy is voted or you vote online at the Annual Meeting.

If your shares are held in street name, you may change or revoke your voting instructions by following the specific directions provided to you by your bank or broker, or you may vote online at the Annual Meeting using your 16-digit control number or otherwise voting through your bank or broker.

A representative of Broadridge Financial Solutions, Inc., our inspector of election, will tabulate and certify the votes.

If you submit a proxy but do not indicate any voting instructions, the persons named as proxies will vote in accordance with the recommendations of the Board. The Board’s recommendations are indicated on page 5 of this proxy statement, as well as with the description of each proposal in this proxy statement.

We know of no other business that will be presented at the Annual Meeting. If any other matter properly comes before the stockholders for a vote at the Annual Meeting, however, the proxy holders named on the Company’s proxy card will vote your shares in accordance with their best judgment.

We believe that hosting a virtual meeting this year is in the best interest of the Company and its stockholders. A virtual meeting also enables increased stockholder attendance and participation because stockholders can participate from any location around the world. You will be able to attend the Annual Meeting online and submit your questions by visiting www.virtualshareholdermeeting.com/GCMG2026. You also will be able to vote your shares electronically at the Annual Meeting by following the instructions above.

We will have technicians ready to assist you with any technical difficulties you may have accessing the virtual meeting website, and the information for assistance will be located on www.virtualshareholdermeeting.com/GCMG2026.

As part of the Annual Meeting, we will hold a live Q&A session, during which we intend to answer questions submitted online during the meeting that are pertinent to the Company and the meeting matters, as time permits. Only stockholders that have accessed the Annual Meeting as a stockholder (rather than a “Guest”) by following the procedures outlined above in “Who can attend the Annual Meeting?” will be permitted to submit questions during the Annual Meeting. Each stockholder is limited to no more than two questions. Questions and answers may be grouped by topic, and substantially similar questions may be grouped and answered as one. We will not address questions that are not pertinent to the business of the Company or the business of the Annual Meeting, or that we otherwise believe are not appropriate under the circumstances.

A “vote withheld,” in the case of the proposal regarding the election of directors, or an “abstention,” in the case of the proposal regarding the ratification of the appointment of Ernst & Young LLP as our independent registered public accounting firm, represents a stockholder’s affirmative choice to decline to vote on a proposal.

Votes withheld and abstentions are counted as present and entitled to vote for purposes of determining a quorum.

Generally, broker non-votes occur when shares held by a broker in “street name” for a beneficial owner are not voted with respect to a particular proposal because the broker (1) has not received voting instructions from the beneficial owner and (2) lacks discretionary voting power to vote those shares. A broker is entitled to vote shares held for a beneficial owner on routine matters, such as the ratification of the appointment of Ernst & Young LLP as our

independent registered public accounting firm, without instructions from the beneficial owner of those shares. On the other hand, absent instructions from the beneficial owner of such shares, a broker is not entitled to vote shares held for a beneficial owner on non-routine matters, such as the election of directors. Broker non-votes count for purposes of determining whether a quorum is present.

We plan to announce preliminary voting results at the Annual Meeting and we will report the final results in a Current Report on Form 8-K, which we intend to file with the SEC after the Annual Meeting.

At the Annual Meeting, seven (7) directors are to be elected to hold office until the Annual Meeting of Stockholders to be held in 2027 and until each such director’s respective successor is elected and qualified or until each such director’s earlier death, resignation or removal.

We currently have seven (7) directors on our Board. Our current directors, who are also director nominees for election at the Annual Meeting, are Michael J. Sacks, Angela Blanton, Francesca Cornelli, David A. Helfand, Jonathan R. Levin, Stephen Malkin and Samuel C. Scott III. The Board has nominated each of the foregoing director candidates to serve as directors until the 2027 Annual Meeting.

The proposal regarding the election of directors requires the approval of a plurality of the votes cast. This means that the seven (7) nominees receiving the highest number of affirmative “FOR” votes will be elected as directors. Votes withheld and broker non-votes are not considered to be votes cast and, accordingly, will have no effect on the outcome of the vote on this proposal.

Upon consummation of the Business Combination, we entered into the Stockholders’ Agreement with the GCMH Equityholders and GCM V, pursuant to which, among other things, (i) GCM V was granted rights to designate all seven directors for election to our Board (and GCM V and the GCMH Equityholders will vote in favor of such designees) and (ii) GCM V and the GCMH Equityholders agreed to vote their voting shares in favor of any recommendations by our Board until the Sunset Date. As a result of the Stockholders’ Agreement and the aggregate voting power of the parties to the agreement, we expect that the parties to the agreement acting in conjunction will control the election of directors at GCM. For more information, see “Corporate Governance—Stockholders’ Agreement.”

In accordance with our Charter and Bylaws, the Board will stand for election for one-year terms that expire at the following year’s annual meeting. Pursuant to our Charter, the total number of directors constituting the Board shall be not less than three (3) and not more than twenty (20), with the then-authorized number of directors being fixed by the Board from time-to-time, which number is currently seven (7) members. Subject to obtaining any required stockholder votes or consents under the Stockholders’ Agreement (or complying with any stockholders’ designation rights under our Stockholders’ Agreement), newly created directorships resulting from any increase in the authorized number of directors or any vacancies on the Board resulting from death, resignation, retirement, disqualification, removal from office or other cause shall be filled solely by the affirmative vote of the remaining directors then in office, even if less than a quorum of the Board. Subject to obtaining any required stockholder votes or consents under the Stockholders’ Agreement, our directors may be removed from office at any time, with or without cause and only by the affirmative vote of the holders of a majority of our outstanding common stock entitled to vote in the election of directors.

The current members of the Board who are also nominees for election to the Board as directors are as follows:

The principal occupations and business experience, for at least the past five years, of each director nominee for election at the Annual Meeting are as follows:

Michael J. Sacks has served as our Chief Executive Officer and Chairman of our Board since our formation in July 2020. Mr. Sacks is also GCM Grosvenor’s Chief Executive Officer, having joined GCM Grosvenor in 1990 and soon after being named its Chief Executive Officer in 1994. Under Mr. Sacks’ leadership, GCM Grosvenor grew from its position as an early participant in a cottage industry to its current position as one of the largest independent open architecture alternative asset platforms. Mr. Sacks is engaged civically, serving on a number of nonprofit boards. In addition to serving as Chairman of our Board, he has served as a member of the boards of CION Grosvenor Infrastructure Fund and CION Grosvenor Infrastructure Master Fund, LLC, closed-end management investment companies where GCM Grosvenor serves as a sub-adviser, since 2024. He graduated from Tulane University with a B.S. in Economics and holds a general course certificate from the London School of Economics. In addition, Mr. Sacks holds an M.B.A. from the Kellogg Graduate School of Management at Northwestern University and a J.D. from Northwestern University’s Pritzker School of Law. Mr. Sacks is well qualified to serve on our Board because of his experience with GCM and GCM Grosvenor, including in his capacity as Chief Executive Officer of each entity.

Jonathan R. Levin joined GCM Grosvenor in 2011, became its President in 2017 and has served as a member of our Board since November 2020. Mr. Levin, in addition to his managerial responsibilities, serves on a number of the firm’s Investment Committees. Prior to joining GCM Grosvenor, Mr. Levin was the Treasurer and Head of Investor Relations at Kohlberg Kravis Roberts & Co. (“KKR”), where he worked from 2004 to 2011, where he was responsible for managing KKR’s balance sheet investments, engaging with public investors and industry analysts, and leading strategic projects. Prior to his role as Treasurer and Head of Investor Relations, Mr. Levin worked in KKR’s private equity business and focused on investments in the financial services industry. Mr. Levin began his career as an Analyst in the private equity group of Bear Stearns. Mr. Levin holds an A.B. in Economics from Harvard College and is a member of the board of directors of the Ann & Robert H. Lurie Children’s Hospital of Chicago, the Museum of Contemporary Art Chicago, and the Francis W. Parker school. Mr. Levin is well qualified to serve on our Board because of his experience with GCM and GCM Grosvenor, including in his capacity as President of each entity, and his experience in the asset management industry.

Angela Blanton has served as a member of our Board since November 2020. Ms. Blanton has served as Carnegie Mellon University’s Vice President for Finance and Chief Financial Officer since 2017 after serving as interim Vice President and Chief Financial Officer in 2016. Ms. Blanton has over 20 years of experience spanning finance, project management and engineering disciplines within the higher education, financial services and manufacturing industries. Prior to joining Carnegie Mellon, Ms. Blanton was Chief Financial Officer for PNC Investments Brokerage from February 2015 to December 2015. Ms. Blanton serves on the boards of the Pittsburgh Public Theater, where she previously served as Chair, and on the Thought Leadership Committee for Pittsburgh’s Allegheny Conference on Community Development and Code for America, Chair. Ms. Blanton received a B.S. in electrical engineering from the University of Michigan and her M.B.A. from the Tepper School of Business at Carnegie Mellon University. We believe Ms. Blanton is well qualified to serve on our Board because of her experience as a chief financial officer and in the financial services industry.

Francesca Cornelli has served as a member of our Board since November 2020. Dr. Cornelli is the dean of Northwestern University’s Kellogg School of Management, a position she has held since August 1, 2019. She is also a professor of finance and holds the Donald P. Jacobs Chair in Finance. Prior to that, she was a professor of finance and deputy dean at London Business School from 1994 to 2019.

In January 2016 she helped create and became a board member of AFFECT, a committee of the American Finance Association designed to promote the advancement of women academics in the field of finance. We believe Dr. Cornelli is well qualified to serve on our Board due to her experience as an academic in finance and governance, and her experience on boards of directors of other companies.

David A. Helfand joined as a member of our Board in February 2025. Mr. Helfand was the President, Chief Executive Officer and Chair of the Board of Equity Commonwealth (NYSE: EQC), a publicly traded real estate investment trust (REIT) that owned and managed commercial office properties in the United States. He had been Chair of the Board of EQC from May 2023 to April 2025 and had been trustee, President and Chief Executive Officer from May 2014 to April 2025.

Mr. Helfand holds an M.B.A. from the University of Chicago Graduate School of Business and a B.A. from Northwestern University. We believe Mr. Helfand is well qualified to serve on our Board due to his extensive business expertise and his experience on boards of directors of other public companies and organizations.

Stephen Malkin has served as a member of our Board since November 2020. Mr. Malkin is President of Ranger Capital Corporation, a position he has held continuously since departing from his position as a senior executive of GCM Grosvenor in 2005. Mr. Malkin was associated with GCM Grosvenor from 1992 through 2005, during most of which time he served on GCM Grosvenor’s Management Committee and shared management responsibilities with Mr. Sacks. Mr. Malkin was also a member of GCM Grosvenor’s Absolute Return Strategies Investment Committee and shared responsibility for portfolio management as well as the evaluation, selection, and monitoring of various Absolute Return Strategies investments. Prior to his role with GCM Grosvenor, from 1988 through 1991, Mr. Malkin worked in various management positions for JMB Realty Corporation, focusing on non-real estate corporate acquisition opportunities. From 1983 to 1986, Mr. Malkin was an analyst with Salomon Brothers Inc. in Chicago and Tokyo. He received a B.B.A. from the University of Michigan and an M.B.A. in Finance from the Wharton School of the University of Pennsylvania. We believe Mr. Malkin is well qualified to serve on our Board because of his management and investment experience with GCM Grosvenor, including as a former GCM Grosvenor Management Committee member and Absolute Return Strategies Investment Committee member, and his experience as an investment professional with over 35 years’ experience.

Samuel C. Scott III has served as a member of our Board since November 2020. Prior to his retirement in 2009, Mr. Scott served as Chairman and Chief Executive Officer, since 2001, and President and Chief Operating Officer, since 1997, of Corn Products International, Inc., a leading global ingredients solutions provider now known as Ingredion Incorporated. Mr. Scott previously served as President of CPC International’s Corn Refining division from 1995 to 1997 and President of American Corn Refining from 1989 to 1997. In addition to his public board service, Mr. Scott also serves on the Board of Trustees of the Ringling College of Art and Design, the board of the Sarasota Memorial Hospital Foundation

and the board of the American Business Immigration Coalition. Mr. Scott served on the board of directors of BNY Mellon from 2003 to 2022, where he served as a member of its Audit Committee, its Human Resources and Compensation Committee and its Corporate Governance, Nominating & ESG Committee. Mr. Scott served on the board of Motorola Solutions, Inc. from 1993 until 2019 and was its lead director from 2015 to 2019. Mr. Scott also served on the board of Abbott Laboratories from 2007 until 2020. Mr. Scott received both a B.S. and an M.B.A. from Fairleigh Dickinson University. We believe Mr. Scott is well qualified to serve on our Board due to his experience as an executive and on boards of directors of other companies.

If you submit a proxy but do not indicate any voting instructions, the persons named as proxies will vote the shares of common stock represented thereby for the election as a director of the person whose name and biography appears below. In the event that any of Mr. Sacks, Ms. Blanton, Dr. Cornelli, Mr. Helfand, Mr. Levin, Mr. Malkin or Mr. Scott should become unable to serve, or for good cause will not serve, as a director, it is intended that votes will be cast for a substitute nominee designated by the Board or the Board may elect to reduce its size. The Board has no reason to believe that any of the director nominees will be unable to serve if elected. Each of the director nominees has consented to being named in this proxy statement and to serve if elected.

Our Audit Committee has appointed Ernst & Young LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2026. Our Board has directed that this appointment be submitted to our stockholders for ratification at the Annual Meeting. Although ratification of our appointment of Ernst & Young LLP is not required, we value the opinions of our stockholders and believe that stockholder ratification of our appointment is a good corporate governance practice.

Ernst & Young LLP also served as our independent registered public accounting firm for the fiscal year ended December 31, 2025. Neither the accounting firm nor any of its members has any direct or indirect financial interest in or any connection with us in any capacity other than as our auditors, providing audit and non-audit related services. A representative of Ernst & Young LLP is expected to attend the Annual Meeting and to have an opportunity to make a statement and be available to respond to appropriate questions from stockholders.

The following table summarizes the fees of Ernst & Young LLP, our independent registered public accounting firm, billed to us for each of the last two fiscal years for audit services and billed to us in each of the last two fiscal years for other services (dollars in thousands).

The Audit Committee has adopted a policy (the “Pre-Approval Policy”) that sets forth the procedures and conditions pursuant to which audit and non-audit services proposed to be performed by the independent auditor may be pre-approved/pre-concurred. The Pre-Approval Policy generally provides that we will not engage Ernst & Young LLP to render any audit, audit-related, tax or permissible non-audit service unless the service is either (i) explicitly approved/concurred by the Audit Committee (“specific pre-approval”) or (ii) entered into pursuant to the pre-approval/pre-concurrence policies and procedures described in the Pre-Approval Policy (“general pre-approval”). Unless a type of service to be provided by Ernst & Young LLP has received general pre-approval under the Pre-Approval Policy, it requires specific pre-approval by the Audit Committee or by a designated member of the Audit Committee to whom the committee has delegated the authority to grant pre-approvals. Any proposed services exceeding pre-approved cost levels or budgeted amounts will also require specific pre-approval. For both types of pre-approval, the Audit Committee will consider whether such services are consistent with the SEC’s rules on auditor independence. The Audit Committee will also consider whether the independent auditor is best positioned to provide the most effective and efficient service, for reasons such as its familiarity with the Company’s business, people, culture, accounting systems, risk profile and other factors, and whether the service might enhance the Company’s ability to manage or control risk or improve audit quality. All such factors will be considered as a whole, and no one factor should necessarily be determinative. The Audit Committee periodically reviews and generally pre-approves any services (and related fee levels or budgeted amounts) that may be provided by Ernst & Young LLP without first obtaining specific pre-approvals from the Audit Committee or the Chair of the Audit Committee. The Audit Committee may revise the list of general pre-approved services from time to time, based on subsequent determinations.

In the event that the appointment of Ernst & Young LLP is not ratified by the stockholders, the Audit Committee will consider this fact when it appoints the independent auditors for the fiscal year ending December 31, 2027. Even if the appointment of Ernst & Young LLP is ratified, the Audit Committee retains the discretion to appoint a different independent auditor at any time if it determines that such a change is in the interest of the Company.

The Audit Committee has reviewed the audited consolidated financial statements of GCM Grosvenor Inc. (the “Company”) for the fiscal year ended December 31, 2025 and has discussed these financial statements with management and the Company’s independent registered public accounting firm. The Audit Committee has also received from, and discussed with, the Company’s independent registered public accounting firm various communications that such independent registered public accounting firm is required to provide to the Audit Committee, including the matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board (“PCAOB”) and the Securities and Exchange Commission.

The Company’s independent registered public accounting firm also provided the Audit Committee with a formal written statement required by PCAOB Rule 3526 (Communications with Audit Committees Concerning Independence) describing all relationships between the independent registered public accounting firm and the Company, including the disclosures required by the applicable requirements of the PCAOB regarding the independent registered public accounting firm’s communications with the Audit Committee concerning independence. In addition, the Audit Committee discussed with the independent registered public accounting firm its independence from the Company.

Based on its discussions with management and the independent registered public accounting firm, and its review of the representations and information provided by management and the independent registered public accounting firm, the Audit Committee recommended to the Board of Directors that the audited consolidated financial statements be included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2025.

Our Board has adopted Corporate Governance Guidelines, a Code of Business Conduct and Ethics, and a charter for our Audit Committee to assist the Board in the exercise of its responsibilities and to serve as a framework for the effective governance of the Company. You can access our Audit Committee charter, our Corporate Governance Guidelines, and our Code of Business Conduct and Ethics on our website at www.gcmgrosvenor.com/corporate-governance, or by writing to our Secretary at our offices at 900 North Michigan Avenue, Suite 1100, Chicago, Illinois 60611.

Our Board currently consists of seven members: Michael J. Sacks, Angela Blanton, Francesca Cornelli, Jonathan R. Levin, David A. Helfand, Stephen Malkin and Samuel C. Scott III. Subject to obtaining any required stockholder votes or consents under the Stockholders’ Agreement, our directors may be removed from office at any time, with or without cause and only by the affirmative vote of the holders of a majority of the total voting power of the outstanding shares of capital stock of the Company entitled to vote generally in the election of directors, voting together as a single class.

Pursuant to the Stockholders’ Agreement, GCM V has rights to designate seven directors for election to our Board and GCM V and the GCMH Equityholders will vote in favor of such designees at any annual or special meeting of stockholders in which directors are elected. Under the terms of the Stockholders’ Agreement, until the Sunset Date, all of our directors are designated by GCM V, of whom three must qualify as “independent directors” under the Nasdaq rules and one must qualify as an “audit committee financial expert” as defined under the rules of the SEC. Thereafter, such designations will be determined by our Board. Pursuant to the terms of the Stockholders’ Agreement, GCM V has the right to remove any of the directors designated by GCM V and will have the exclusive right to designate directors to fill vacancies created by reason of death, removal or resignation of any director designated by GCM V.

We are a “controlled company” under the Nasdaq rules. As a result, we qualify for exemptions from, and have elected not to comply with, certain corporate governance requirements under the rules, including the requirements that we have a compensation committee and a nominating committee that are composed entirely of independent directors. We do not maintain a compensation committee or a nominating committee. Even though we are a controlled company, we are required to comply with the rules of the SEC and the Nasdaq rules relating to the membership, qualifications and operations of our audit committee.

The Nasdaq rules define a “controlled company” as a company of which more than 50% of the voting power for the election of directors is held by an individual, a group or another company. As of April 10, 2026, the Key Holders control approximately 75% of the combined voting power of the Company’s common stock, and control a majority of the voting power of the Company so long as the outstanding Class C common stock represents at least 9.1% of the Company’s total outstanding common stock. Accordingly, we qualify as a “controlled company”. If we cease to be a controlled company and our Class A common stock continues to be listed on the Nasdaq Global Market, we will be required to comply with the Nasdaq requirements for non-controlled companies by the date our status as a controlled company changes or within specified transition periods applicable to certain provisions, as the case may be.

In making its independence determinations, the Board reviewed and discussed information provided by the directors with regard to each director’s business and personal activities and any relationships they have with us and our management. As a result of this review, our Board determined that Ms. Blanton, Dr. Cornelli, Mr. Helfand and Mr. Scott are “independent directors” as defined under the applicable Nasdaq rules, representing four of our seven directors.

In addition, each of the members of the Audit Committee, Ms. Blanton, Dr. Cornelli, Mr. Helfand and Mr. Scott, meets the heightened independence standards required for audit committee members under the applicable Nasdaq rules and SEC rules. There are no family relationships among any of our directors or executive officers.

As discussed above, we are a controlled company and do not have a nominating committee. Subject to the terms of the Stockholders’ Agreement, the Board is primarily responsible for searching for qualified director candidates for election to the Board and filling vacancies on the Board. The Board currently does not have a policy with regard to the

consideration of any director candidates recommended by stockholders, other than pursuant to the Stockholders’ Agreement, but may implement such a policy in the future. The Board believes it is appropriate not to have such a policy in place at this time, in light of the Board designation rights provided to GCM V in the Stockholders’ Agreement.

In evaluating the suitability of individual candidates (both new candidates and current Board members), the Board, in approving (and, in the case of vacancies, appointing) candidates for election, will consider candidates who have a high level of personal and professional integrity, strong ethics and values and the ability to make mature business judgments. In evaluating director candidates, the Board may also consider any other factor that they may deem to be relevant, including but not limited to the candidate’s professional and academic experience and skills. In addition, the Board will consider whether there are potential conflicts of interest with the candidate’s other personal and professional pursuits. Each individual will be evaluated in the context of the Board as a whole, with the objective of recommending a group that can best perpetuate the success of the Company’s business.

The Board will give appropriate attention to written communications that are submitted by stockholders, and will respond if and as appropriate. Our Secretary is primarily responsible for monitoring communications from stockholders and for providing copies or summaries to the directors as he considers appropriate.

Communications are forwarded to all directors if they relate to important substantive matters and include suggestions or comments that our Secretary and Chairman of the Board consider to be important for the directors to know. In general, communications relating to corporate governance and long-term corporate strategy are more likely to be forwarded than communications relating to ordinary business affairs, personal grievances and matters as to which we tend to receive repetitive or duplicative communications. Stockholders who wish to send communications on any topic to the Board should address such communications to the Board in writing: c/o Secretary, GCM Grosvenor Inc., 900 North Michigan Avenue, Suite 1100, Chicago, Illinois 60611.

Our Bylaws and Corporate Governance Guidelines provide our Board with flexibility to combine or separate the positions of Chairman of the Board and Chief Executive Officer in accordance with its determination that utilizing one or the other structure would be in the best interests of our Company. Currently, the roles are combined, with Mr. Sacks serving as Chairman of the Board and Chief Executive Officer. Our Board has determined that combining the roles of Chairman of the Board and Chief Executive Officer is in the best interests of our Company and its stockholders at this time because it promotes unified leadership by Mr. Sacks and allows for a single, clear focus for management to execute the Company’s strategy and business plans.

Our Corporate Governance Guidelines provide that whenever the Chair of the Board is also a member of management or is a director that does not otherwise qualify as an independent director, the independent directors may elect a lead director whose responsibilities include, but are not limited to, presiding over all meetings of the Board at which the Chair of the Board is not present, including any executive sessions of the independent directors; approving Board meeting schedules and agendas; and acting as the liaison between the independent directors and the Chair of the Board, as appropriate. Currently, Mr. Scott serves as our Lead Independent Director. Due to the strong leadership of Mr. Sacks, coupled with the independent oversight provided by our Lead Independent Director and our independent Audit Committee, our Board has concluded that our current leadership structure is appropriate at this time. However, our Board will continue to periodically review our leadership structure and may make such changes in the future as it deems appropriate.

Risk assessment and oversight are an integral part of our governance and management processes. Our Board encourages management to promote a culture that incorporates risk management into our corporate strategy and day-to-day business operations. Management discusses strategic and operational risks at regular management meetings and conducts specific strategic planning and review sessions during the year that include a focused discussion and analysis of the risks facing us. Throughout the year, senior management intends to review these risks with the Board at regular Board meetings as part of management presentations that focus on particular business functions, operations or strategies, and presents the steps taken by management to mitigate or eliminate such risks. Our Board does not have a standing risk management committee, but rather administers this oversight function directly through the Board as a whole, as well as through its Audit Committee, which oversees risks inherent in its area of oversight. In particular, our Board is responsible for monitoring and assessing strategic risk exposure, including our credit, liquidity and operations, and our Audit Committee is responsible for overseeing our financial, cybersecurity and information security risk

exposures and the steps our management has taken to monitor and control these exposures. The Audit Committee also monitors compliance with legal and regulatory requirements and considers and approves or disapproves any related person transactions. While the Audit Committee is responsible for evaluating certain risks and overseeing the management of such risks, the entire Board has an active role in overseeing management of the Company’s risks and is regularly informed through Committee reports about such risks. The Board does not believe that its role in the oversight of our risks affects the Board’s leadership structure.

We have a written Code of Business Conduct and Ethics that applies to our directors, officers and employees, including our principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions. A copy of the Code of Business Conduct and Ethics is posted on our website, www.gcmgrosvenor.com/governance. In addition, we intend to post on our website all disclosures that are required by law or the rules of Nasdaq concerning any amendments to, or waivers from, any provision of the Code of Business Conduct and Ethics.

Our Board has adopted an Insider Trading Compliance Policy and Procedures governing the purchase, sale and/or other dispositions of our securities by our directors, officers and employees. We believe that our Insider Trading Compliance Policy and Procedures are reasonably designed to promote compliance with insider trading laws, rules and regulations, and any listing standards applicable to us. It is also our policy to comply with applicable insider trading laws and regulations with respect to transactions in our own securities. A copy of the Insider Trading Compliance Policy and Procedures is filed as Exhibit 19.1 to our Annual Report on Form 10-K for the year ended December 31, 2025.

The Insider Trading Compliance Policy also prohibits our directors, officers and employees and any entities they control from purchasing financial instruments such as prepaid variable forward contracts, equity swaps, collars, and exchange funds, or otherwise engaging in transactions that hedge or offset, or are designed to hedge or offset, any decrease in the market value of the Company’s equity securities, or that may cause an officer, director, or employee to no longer have the same objectives as the Company’s other stockholders.

At our firm, we believe culture is one of our most important and defensible assets. Our clients hire us to be their essential long-term partners, so their comfort with the firm and team is a critical component of their diligence on our organization. That investment in culture is reflected in the stability and inclusivity of our team as well as the fact that we do not operate on a star system and therefore are not beholden to any one individual. We aim to invest responsibly, operate our business with integrity, and build an inclusive workplace where our employees can thrive. We have been a registered investment adviser since 1997 with a culture of compliance rooted in what we believe is a proper tone at the top.

In addition to a competitive compensation structure, we promote a work environment that we believe is interesting and challenging, providing our employees the opportunity to grow professionally. We also seek to foster strong alignment between our employees and clients. As of December 31, 2025, our current employees, former employees and the firm had approximately $836 million of their own capital (including through leveraged vehicles) invested into our various investment programs, which we believe aligns our interests with those of our clients.

There were five meetings of the Board and four meetings of the Audit Committee during the fiscal year ended December 31, 2025. During the fiscal year ended December 31, 2025, each director attended at least 75% of the aggregate of (i) all meetings of the Board and (ii) with respect to the members of the Audit Committee, all meetings of the Audit Committee.

Under our Corporate Governance Guidelines, which is available on our website at https://www.gcmgrosvenor.com/governance/, a director is expected to spend the time and effort necessary to properly discharge his or her responsibilities. Accordingly, a director is expected to regularly prepare for and attend meetings of the Board and any committee on which the director sits (including separate meetings of the independent directors), with the understanding that, on occasion, a director may be unable to attend a meeting. A director who is unable to attend a meeting of the Board or a committee of the Board is expected to notify the Chair

of the Board or the Chair of the appropriate committee in advance of such meeting, and, whenever possible, participate in such meeting via teleconference in the case of an in-person meeting. We do not maintain a formal policy regarding director attendance at the Annual Meeting; however, it is expected that absent compelling circumstances directors will attend. Mr. Sacks, Mr. Levin, Ms. Blanton, Dr. Cornelli, Mr. Helfand, Mr. Malkin and Mr. Scott attended the 2025 Annual Meeting of Stockholders.

Our Board has established a standing Audit Committee, which operates under a written charter that has been approved by our Board.

As a controlled company, we do not have a compensation committee of the Board, or a committee performing equivalent functions. Our Board is primarily responsible for establishing and administering our policies governing the compensation of our executive officers and directors. Our Board is also primarily responsible for determining the compensation of our Chief Executive Officer and for making equity grants to our Chief Executive Officer and other executive officers. The Board has delegated authority to Michael J. Sacks to make certain determinations regarding cash compensation paid to our executive officers, other than with respect to his own cash compensation. Michael J. Sacks, our Chief Executive Officer, and Jonathan R. Levin, our President, participated in our Board’s deliberations regarding executive officer and director compensation during the year ended December 31, 2025.

Our Audit Committee’s responsibilities include:

The Audit Committee charter is available on our website at https://www.gcmgrosvenor.com/governance/. The members of the Audit Committee are Ms. Blanton, Dr. Cornelli, Mr. Helfand and Mr. Scott. Mr. Helfand serves as the Chairperson of the committee. Our Board has affirmatively determined that each of Ms. Blanton, Dr. Cornelli, Mr. Helfand and Mr. Scott is independent for purposes of serving on an audit committee under Rule 10A-3 promulgated under the Exchange Act and the Nasdaq rules, including those related to Audit Committee membership.

The members of our Audit Committee meet the requirements for financial literacy under the applicable Nasdaq rules. In addition, our Board has determined that each of Ms. Blanton, Dr. Cornelli and Mr. Helfand qualifies as an “audit committee financial expert,” as such term is defined in Item 407(d)(5) of Regulation S-K, and under the similar Nasdaq rules requirement that the Audit Committee have a financially sophisticated member.

The Audit Committee met four times in 2025.

The following table identifies our current executive officers:

In 2025, our “named executive officers” or “NEOs”, and their positions were as follows:

This Compensation Discussion and Analysis provides an overview and description of our executive compensation philosophy and each element of fiscal 2025 compensation awarded to, earned by or paid to our NEOs during fiscal 2025.

The success of our business depends on the efforts, judgment and reputations of our talent and, in particular, our experienced and senior people in investment, operational and executive functions. Our people’s reputation, expertise in investing and risk management, relationships with our clients and third parties on which our funds depend for investment opportunities are each critical elements in operating and growing our business. The business we operate in is intensely competitive, and our ability to continue to compete effectively depends upon our ability to continue to attract highly qualified investment professionals and the retention and development of existing employees.

In order to attract and retain talented current and prospective employees, we have developed a comprehensive total rewards program. The components of this program are designed to recognize and reward individual performance and recognize contributions that align with and drive positive business results. Executive compensation at GCM Grosvenor is aligned with Company, client and individual performance. We believe that our compensation program incentivizes behaviors and actions that grow shareholder value and closely align the interests of our employees with those of our shareholders.

In 2025, GAAP Net Income Attributable to GCM Grosvenor Inc. increased 143% to $45.4 million, Fee-Related Earnings increased 11% to $185.1 million, Adjusted EBITDA increased 15% to $245.6 million, and Adjusted Net Income increased 18% to $166.3 million. AUM reached a new high-water mark of $90.9 billion at year-end, up 14% year-over-year. Fee-Paying AUM increased 12% to $72.5 billion. Investment performance was very strong, as our Absolute Return Strategies multi-strategy composite generated a 15% gross return for the year, and performance across our other verticals was similarly positive and competitive. During the year we raised $10.7 billion of total capital, making 2025 the strongest fundraising year in the history of the firm. Against this backdrop, the Compensation Discussion and Analysis below explains how our program design rewarded these outcomes. For a reconciliation of non-GAAP measures to the corresponding GAAP measures, please see Appendix A: Reconciliation of Non-GAAP Measures. In order to attract, retain, reward and motivate talented executives, including our NEOs, our executive compensation program consists of the following components:

We believe these components of compensation result in an effective mix of fixed and variable compensation and balance short-term and long-term compensation considerations that are closely tied to the growth of our firm and enhanced

shareholder value. In addition, we believe these compensation components further attract and incentivize talent, provide an overall compensation package that is competitive with the market and encourages retention of top performers.

We are a “controlled company” under the Nasdaq rules, and therefore we are not required to have a compensation committee. Other than with respect to Mr. Sacks’ compensation, our Board has delegated the authority to approve our NEOs’ compensation to our Chief Executive Officer. The Board is responsible for approving Mr. Sacks’ compensation and approved his compensation as set forth pursuant to his employment agreement. Mr. Sacks’ compensation reflects his long-standing service as founder and Chief Executive Officer. His economic alignment with stockholders is achieved principally through his substantial ownership of Grosvenor common units and interests in Holdings, which represent approximately 70% of the total economic interest in GCM Grosvenor’s business. Mr. Sacks also participates in the Company’s carried interest arrangements, which provide direct exposure to fund performance outcomes. The compensation for Messrs. Levin and Pollock and Mses. Bentley and Buchanan was approved by our Chief Executive Officer. The Board makes all final determinations regarding equity grants to our NEOs pursuant to the GCM Grosvenor Inc. Amended and Restated 2020 Incentive Award Plan (the “Amended and Restated Incentive Award Plan”).

While we did not retain a compensation consultant specifically to advise on our compensation of our NEOs during fiscal 2025, we utilize compensation consultants in connection with the design and benchmarking of our broader employee compensation programs. In determining the compensation of our NEOs, management reviewed publicly available compensation data for a group of publicly traded alternative asset managers with which we compete for executive talent. This review informed our assessment of whether NEO compensation levels were competitive with market practice, though we did not engage in formal benchmarking against a defined peer group for purposes of setting individual NEO pay. We believe that this approach, combined with our direct knowledge of market conditions gained through our recruiting and retention activities, provides a sufficient basis for assessing the competitiveness of our executive compensation program.

In 2024, we held a “say-on-pay” vote on the Company’s executive compensation program as set forth at the 2024 annual meeting of stockholders and 91% of the votes cast by stockholders voted “for” the proposal. Given that a substantial majority of stockholders approved the executive compensation program, we continued to apply substantially similar principles in determining the amounts and types of executive compensation and did not implement significant changes as a result of the stockholder advisory vote. We regularly engage with our stockholders on governance and compensation matters through investor relations activities and conferences, and we consider feedback received through these interactions in connection with our compensation decisions. Our next say-on-pay vote will be held in fiscal year 2027.

In order to attract, retain, motivate and reward our NEOs, we take a holistic approach to compensation with a focus on total rewards, which consists of the components described below.

Each of our NEOs is entitled to receive a base salary in an amount set forth in their respective employment agreements, the terms of which are summarized below. The base salaries compensate our NEOs for services rendered to our firm. The base salary payable to each named executive officer is intended to provide a fixed component of compensation reflecting the executive’s skill set, experience, role and responsibilities. The actual base salaries paid to each named executive officer for fiscal 2025 are set forth below in the Summary Compensation Table in the column titled “Salary”.

Each of our NEOs other than Mr. Sacks and Ms. Buchanan received discretionary annual performance bonuses with respect to services in fiscal 2025. Under their employment agreements, our NEOs other than Mr. Sacks are entitled to receive annual bonuses, each of which is determined in the sole discretion of the firm. Under the Second Amended and Restated Employment and Protective Covenants Agreement, by and between Mr. Pollock and GCMLP, dated May 9, 2023 (the “Pollock employment agreement”), Mr. Pollock’s total cash receipts (comprised

of his base salary, any annual cash bonus and distributions from Holdings) for bonus periods in respect of calendar years 2023, 2024, and 2025 must meet certain minimum amounts. Following the expiration of his guaranteed compensation schedule, Mr. Pollock’s future compensation, including his annual bonus, will be determined at the discretion of GCMLP consistent with the Company’s overall compensation program. The size of our annual bonus pool for bonus-eligible employees is determined by our operating results.

Annual bonuses are intended to reward our NEOs, other than Mr. Sacks, for strong financial performance and helping us achieve our annual goals. Annual bonus awards are made taking into account the performance measures described above in “Compensation Discussion and Analysis – Compensation Philosophy” to link executive compensation paid for fiscal 2025 to the Company’s performance, and the size of our bonus pool for bonus-eligible employees is determined by our operating results and the amount of incentive fee revenue recognized during the year. The factors that were considered in determining the size of the bonus paid to each NEO, other than Mr. Sacks, include (i) Company financial performance, including GAAP Net Income Attributable to GCM Grosvenor Inc. of $45.4 million, Fee-Related Earnings of $185.1 million, Adjusted EBITDA of $245.6 million and Adjusted Net Income of $166.3 million, (ii) AUM growth and new capital raised during the year, (iii) individual performance and contributions assessed through annual reviews, (iv) contributions and accomplishments in leading and managing the Company and its teams, (v) contributions to support growth of our shareholder value and (vi) relative performance compared to prior year performance and to our other executive-level employees. For a reconciliation of non-GAAP measures to the corresponding GAAP measures, please see Appendix A: Reconciliation of Non-GAAP Measures.

Please see the section titled “Bonuses” below the Summary Compensation Table for more information.

We currently maintain the Amended and Restated Incentive Award Plan in order to facilitate the grant of cash and equity incentives to directors, employees (including our NEOs), and consultants of our company and certain of its affiliates and to enable our company and certain of its affiliates to obtain and retain services of these individuals, which is essential to our long-term success. Each of our NEOs is entitled to receive equity compensation pursuant to the Amended and Restated Incentive Award Plan, which must be approved by our Board. In fiscal 2025 we determined the amount of equity awards awarded to our NEOs based on a holistic review of their respective total compensation packages and based on firm and individual performance in connection with annual performance reviews conducted with senior management, as well as pursuant to contractual entitlements described in the section titled “Employment Agreements” below. Notwithstanding that Mr. Sacks is eligible to receive awards under the Amended and Restated Incentive Award Plan, we did not issue such awards to Mr. Sacks in fiscal 2025.

We have utilized awards of RSUs that vest over a three-year period, subject to continued service through the applicable vesting date, as our primary form of long-term equity compensation. We believe that the three-year vesting period promotes employee retention and encourages our employees to focus on our long-term strategic objectives and appreciation in shareholder value. In addition, we have utilized awards that vest over a period of less than three years to promote greater equity ownership as a percentage of total rewards, which we believe aligns our employees’ interests with those of our shareholders.

Commencing in fiscal year 2025, we have granted long-term RSU awards with four-year and seven-year, back-loaded vesting schedules to a select group of high-performing senior leaders at the firm, including Ms. Bentley, as described below. These awards recognize sustained individual performance and exceptional contributions to the firm and are intended to serve as a meaningful long-term retention incentive for talent we consider critical to the Company’s continued growth. The awards also strengthen the alignment between the long-term economic interests of our senior leadership and those of our stockholders. We selected a back-loaded vesting structure — under which a significant majority of RSUs vest in the later years of the vesting period — because we believe it creates a stronger and more sustained retention incentive than a ratable or front-loaded schedule, preserving the value of the award throughout its full term and increasing the economic cost of departure prior to vesting. The four-year and seven-year terms were chosen to align the retention horizon of these awards with the Company’s long-term strategic objectives and with the extended time horizons over which value is created in the alternative asset management industry.

Under his employment agreement, Mr. Pollock is entitled to be granted 150,000 RSUs in calendar years 2023, 2024, and 2025 which vest over a three-year period following the respective dates of grant, subject to Mr. Pollock’s continued service through the applicable vesting date, and subject to Board approval (as described in the section

titled “Employment Agreements – Frederick E. Pollock” below). On March 1, 2025, our Board approved grants of RSU awards to each of Messrs. Levin and Pollock and Mses. Bentley and Buchanan pursuant to the Amended and Restated Incentive Award Plan. The RSU awards vest over a three-year period in equal annual installments, subject to the NEOs’ continued service with the Company through the applicable vesting date.

In addition, each of Messrs. Levin and Pollock received a grant of RSUs on March 1, 2025, that vested subject to continued service through August 15, 2025. Ms. Bentley received a grant of RSUs on January 15, 2025, that vested subject to continued service through April 15, 2025, a grant of RSUs on March 1, 2025, which vests on May 31, 2029 subject to continued service and two grants of RSUs on November 15, 2025, the first of which vested on March 1, 2026, and the second of which that vests in installments on May 15, 2028, May 15, 2030, May 15, 2031 and May 15, 2032, subject to continued service through the applicable vesting date. Ms. Buchanan received a grant of RSUs on January 15, 2025, that vested subject to continued service through April 15, 2025, and a grant of RSUs on March 1, 2025, that would have vested on May 31, 2029 subject to continued service but was forfeited upon her departure as described below.

Please see the sections titled “Equity Compensation” below the Summary Compensation Table and “Grants of Plan-Based Awards” for more information.

Forfeiture Upon Departure. In connection with her resignation effective October 3, 2025, Ms. Buchanan forfeited all unvested RSU awards as of her departure date. For additional information regarding the treatment of Ms. Buchanan’s compensation elements upon her resignation, see “Quantification of Potential Payments Upon Termination or Change in Control” below.

Senior employees including our NEOs are eligible to participate in our carried interest arrangements. Distributions of carried interest under these arrangements reflect receipt of a portion of the incentive compensation earned by our funds based on fund performance. Amounts received from our carried interest arrangements are dependent upon the success of our fund investments and therefore, incentivize behavior that is aligned with successful fund performance, our investors and our shareholders. These awards, including those made to our NEOs, are determined in conjunction with bonus and total rewards determinations based on firm and individual performance in connection with annual performance reviews conducted with senior management. They generally vest based on the continued performance of services over a multi-year period and may be subject to reduction or forfeiture under certain circumstances. The service-based vesting criteria promote employee retention during the applicable vesting period.

Please see the section titled “Carried Interest” below the Summary Compensation Table for more information.

Holdings. Messrs. Sacks, Levin and Pollock (or their estate planning vehicles) hold membership interests in Holdings, an entity controlled by Mr. Sacks, and Ms. Buchanan (or her estate planning vehicles) held a membership interest in Holdings during 2025. The membership interests held by Mr. Sacks entitle him to distributions by Holdings to its members and proceeds from capital transactions. The membership interests held by Messrs. Levin and Pollock entitle them to a stated percentage, or minimum allocable share, of distributions from Holdings, as well as a profits interest with respect to net sale proceeds from dispositions of Holdings properties after certain threshold distributions to other members. The membership interest previously held by Ms. Buchanan entitled her to distributions in amounts determined by the managing member of Holdings in its sole discretion. In determining the amount of any discretionary distributions to Ms. Buchanan during 2025, the managing member of Holdings considered Ms. Buchanan’s performance and contributions to the overall success of our business and Holdings’ financial performance during the year. Ms. Buchanan’s membership interest in Holdings terminated effective September 30, 2025 in connection with her resignation.

Management LLC. Mses. Bentley and Buchanan hold membership interests in Management LLC, an entity controlled by Mr. Sacks, which entitle them to a portion of all profits distributed by Management LLC to its members, but not to proceeds from any capital transaction. The portion of profits distributed is determined by the managing member of Management LLC in its sole discretion. In determining the amount of any discretionary distributions to Mses. Bentley and Buchanan, the managing member of Management LLC considers each of Mses. Bentley and Buchanan’s respective performance and contributions to the overall success of our business and

Management LLC’s financial performance during the applicable fiscal year. Ms. Buchanan’s membership interest in Management LLC was not terminated upon her resignation and will terminate in connection with the delivery of her Management Award Interests (as described below) on May 1, 2030. Post-departure distributions from Management LLC are expected to be paid to Ms. Buchanan through such date in accordance with the governing documents of that entity.

Employee Benefits. All of our employees including our NEOs have the opportunity to participate in an employee benefit package that we consider to be favorably competitive among alternative investment firms, including:

401(k) Retirement Plan. We maintain a 401(k) retirement savings plan (the “401(k) Plan”) for our employees and each of our NEOs is eligible to participate in our 401(k) Plan. The 401(k) Plan facilitates retirement planning in a tax efficient manner by allowing eligible employees to defer a portion of their compensation, within prescribed limits, on a pre-tax basis through contributions. Currently, we match contributions made by participants in the 401(k) Plan up to a specified percentage of the employee contributions, and upon completion of two years of service, these matching contributions are fully vested as of the date on which the contribution is made. For employees with less than two years of service, the matching contributions are 50% vested after one year of service and fully vested after two years of service. We believe that providing a vehicle for tax-deferred retirement savings though our 401(k) plan, and making fully vested matching contributions, adds to the overall desirability of our executive compensation package and further incentivizes our employees, including our NEOs, in accordance with our compensation policies.

Non-Commercial Air Travel. Pursuant to their employment agreements with the Company, each of Messrs. Sacks, Levin and Pollock may use non-commercial air travel services for personal purposes up to an annual cap on the aggregate total cost to the Company in any one calendar year as set forth in their respective employment agreements. The dollar amount of such personal use is calculated in accordance with company policies and procedures. We believe that providing access to non-commercial air travel serves important business purposes, including security during travel and the efficiency of our executives who engage in frequent travel to meet with investors, portfolio companies, and fund managers across multiple time zones.

Housing Allowance. Ms. Bentley is eligible to receive a housing allowance for temporary housing in Chicago, and Ms. Buchanan was eligible to receive a housing allowance for temporary housing in Chicago prior to termination in 2025. We believe providing our NEOs such benefit is appropriate to assist them in the performance of their duties and makes them more efficient by reducing required travel time.

Please see the section titled “Perquisites and Other Personal Benefits” below the Summary Compensation Table for more information.

Compensation and Risk. Senior management annually considers potential risks when reviewing our compensation programs and practices for all employees generally, including with respect to compensation elements, fixed and variable compensation and short-term and long-term compensation. Based on its evaluation, the senior management has concluded that the risks arising from our overall compensation policies and practices are not reasonably likely to have a material adverse effect on our Company. Our compensation program includes elements that we believe discourage excessive risk-taking and align the compensation of our employees with the long-term performance of the Company and its shareholders.

Tax and Accounting Considerations. Section 162(m) of the Internal Revenue Code of 1986 generally disallows publicly-listed companies a tax deduction for compensation in excess of $1,000,000 paid to “covered employees” of

such company, which “covered employees” can include the chief executive officer, the chief financial officer, the three other highest paid executive officers and certain individuals who were previously “covered employees”. While we consider the impact of developments and changes in accounting standards and tax law in making our compensation decisions, we maintain our flexibility to provide our NEOs non-deductible incentive compensation if we determine that doing so appropriately aligns our executive compensation program with our overall executive compensation philosophy and objectives.

Clawback Policy. Our Clawback Policy, which was adopted in 2023 and amended and restated in 2024, covers all current and former Section 16 officers of GCM Grosvenor Inc. The policy is intended to be compliant with Listing Rule 5608 adopted by the Nasdaq Stock Market to implement Rule 10D-1 under the Exchange Act. The policy requires the Company to recover incentive-based compensation (including equity awards whose vesting is tied to financial reporting measures) that was erroneously awarded due to a required accounting restatement, covering the three fiscal years preceding the restatement. Recovery is required regardless of executive misconduct, and the Company does not indemnify any covered executive against such recovery. During fiscal 2025, no events occurred that triggered the recovery provisions of our Clawback Policy.

Prohibition on Hedging and Pledging. Our NEOs, members of their immediate families and households and their controlled entities are prohibited from engaging in transactions that hedge or offset, or are designed to hedge or offset, any decrease in the market value of GCM Grosvenor securities and from pledging GCM Grosvenor securities as collateral for a loan.

Our Board does not have a compensation committee. The below Board members reviewed and had the opportunity to discuss with management the foregoing Compensation Discussion and Analysis and, based on such review and discussion, determined that the foregoing Compensation Discussion and Analysis be included in this proxy statement and incorporated by reference in our Annual Report on Form 10-K for the year ended December 31, 2025.

The following table sets forth information concerning the compensation of our NEOs for our fiscal years ended December 31, 2025, December 31, 2024 and December 31, 2023.

The following table sets forth information regarding equity awards granted to NEOs during fiscal 2025.

Under their employment agreements, Mr. Levin and Mses. Bentley and Buchanan were entitled to receive annual bonuses, each of which is determined in the sole discretion of GCMLP. Under the Pollock employment agreement, Mr. Pollock is entitled to total cash compensation (comprised of his base salary, any annual cash bonus, and distributions from Holdings) in respect of calendar years 2023, 2024, and 2025 in aggregate amounts of $4,500,000, $5,000,000, and $6,000,000, respectively. To the extent the annual cash bonus is paid in the following calendar year but relates to performance in respect of the prior year, such bonus is included in the prior year’s calculation of total cash compensation. Mr. Pollock is eligible for a cash bonus in respect of calendar year 2023, 2024 and 2025, in an amount to be determined in the sole discretion of GCMLP, provided that such each annual bonus is expected to be at least $1,000,000. A significant portion of the total cash compensation to which Mr. Pollock is entitled is derived from distributions from Holdings, pursuant to his minimum stated percentage of distributions from that entity. Following the expiration of his guaranteed compensation schedule, Mr. Pollock’s future compensation will be determined at the discretion of GCMLP consistent with the Company’s overall compensation program. Effective March 1, 2025, Mr. Pollock and GCMLP acknowledged and agreed that an award of 52,500 RSUs granted to Mr. Pollock on March 1, 2025 that vested on August 15, 2025 would reduce the total cash compensation for the bonus period in respect of calendar year 2024 by an amount equal to $672,000. The actual annual cash bonuses awarded to each NEO for 2025, 2024 and 2023 performance are set forth above in the Summary Compensation Table in the column entitled “Bonus”.

In January 2025, the Company granted Mses. Bentley and Buchanan 14,708 RSUs and 8,604 RSUs, respectively. In March 2025, the Company granted Messrs. Levin and Pollock and Mses. Bentley and Buchanan 228,750 RSUs, 202,500 RSUs, 91,250 RSUs and 70,000 RSUs, respectively. In November 2025, the Company granted Ms. Bentley 639,845 RSUs. For more information on such RSU awards, see the “Grants of Plan-Based Awards” table above.

Ms. Buchanan forfeited all unvested RSUs, a total of 109,193 unvested RSUs, upon her termination on October 3, 2025.

Messrs. Levin and Pollock have the right to receive a bonus if GCMLP receives performance fees from GCM Grosvenor Opportunistic Credit Fund IV, Ltd., GCM Grosvenor Opportunistic Credit Master Fund IV, Ltd., and GCM Principal SPV, Ltd. - Class B. Mr. Levin has a right to receive a bonus if GCMLP receives performance fees from GCM Grosvenor Opportunistic Credit Fund III, Ltd., GCM Grosvenor Opportunistic Credit Master Fund III, Ltd., Grosvenor Opportunistic Credit Fund III (TI), L.P., and Grosvenor Opportunistic Credit Master Fund III (TI), L.P. Bonus amounts are calculated as the product of a stated award percentage (as set forth in individual award letters) and the incentive fees earned by GCMLP from the funds set forth above. Our executives must be employed on the date the cash bonus is paid in order to receive a bonus under these arrangements. None of our executives received any bonuses with respect to these arrangements in 2025.

GCMLP and its affiliates sponsor a deferred compensation plan under which employees, including the NEOs, may be selected to receive a bonus (or to have a portion of their annual bonus deferred) under the provisions of the plan. Under the plan, unless an employee’s individual award agreement provides otherwise, bonuses will vest 20% per year over five years (or in full upon death or disability or determination by the plan administrator in its discretion) and will be credited with gains and losses commensurate with (i) the cumulative return on investments made by GCMH in select investment strategies managed by GCMLP and its affiliates, excluding carried interest arrangements, (ii) such other investment fund, benchmark or index reasonably determined from time to time by the company or (iii) as otherwise described in an award agreement. Awards for the 2019 series are currently fully vested and are paid out in ten installments, in accordance with the following schedule: (i) 5% on the first May 31 following the anniversary of the bonus vesting commencement date, (ii) 5% on each of the next three anniversaries thereof, (iii) 10% on the next two anniversaries thereof, and (iv) 15% on the next four anniversaries thereof. Awards are paid out in seven installments for the 2020 series, in accordance with the following schedule: (i) 10% on the May 31 following the anniversary of the bonus vesting commencement date, (ii) 10% on each of the next three anniversaries thereof, and (iii) 20% on the next three anniversaries thereof. These percentages are applied to the entire award, including all earnings with which it is then credited, and not just to the vested portion of the award.

The aggregate incremental cost to the Company of use of non-commercial air travel services for personal use by our NEOs in 2025 was $1,915,873, which is our actual cost based on a charter rate allocated to each individual, and the specific amounts received by each of Messrs. Sacks and Levin is set forth in the “All Other Compensation” column of the Summary Compensation table, above, and the accompanying footnotes. In each case, the personal use by Messrs. Sacks and Levin was within the annual cap on aggregate personal use costs set forth in their respective employment agreements. Mr. Pollock did not use this benefit for personal purposes in 2025. Please see the section titled “Certain Relationships and Related Person Transactions - Firm Use of Private Aircraft” for more information.

The aggregate incremental cost to the Company of housing allowances received by our NEOs in 2025 was $148,147, which is our actual cost based on rent expense, and the specific amounts received by each of Mses. Bentley and Buchanan is set forth in the “All Other Compensation” column of the Summary Compensation table, above, and the accompanying footnotes.

Messrs. Sacks, Levin and Pollock, and Mses. Bentley and Buchanan participate in our carried interest arrangements and are entitled to specified percentages (the “carried interest sharing percentages”) of distributions of carried interest from the tranche(s) set forth in such officer’s carried interest award agreements. These awards may be subject to reduction or

forfeiture under certain circumstances, as described below under “Termination Payments and Benefits”. Certain carried interest arrangements may be subject to minimum distribution percentages and target amounts. Under his employment agreement, Mr. Pollock is entitled to receive 10% of the total carried interest associated with programs managed by the Company’s Strategic Investments Group and 5% of the carried interest associated with the Company’s private markets investment strategies, and not less than 5% of any carried interest or incentive economics associated with newly created specialized funds that pursue absolute return strategies, provided such interests are otherwise awarded to other members of senior management of the Company. Messrs. Sacks, Levin and Pollock, and Mses. Bentley and Buchanan received cash distributions in respect of their carried interest awards for fiscal year 2025, the amounts of which are set forth in the “All Other Compensation” column of the Summary Compensation table, above, and the accompanying footnote.

Messrs. Sacks, Levin and Pollock (or their estate planning vehicles) hold membership interests in Holdings, an entity controlled by Mr. Sacks, and Ms. Buchanan (or her estate planning vehicles) held membership interests in Holdings during 2025. The membership interests held by Mr. Sacks entitle him to distributions by Holdings to its members and proceeds from capital transactions, and the membership interests previously held by Ms. Buchanan entitled her to distributions in amounts determined by the managing member of Holdings in its sole discretion during 2025.

Prior to May 9, 2023, the membership interests in Holdings held by Messrs. Levin and Pollock (the “Original Holdings Award Interests”) entitled them each to a fixed portion of profits distributed by Holdings to its members and to additional discretionary distributions in amounts determined by the managing member of Holdings. In addition, in connection with a termination of employment pursuant to their respective employment agreements, Messrs. Levin and Pollock were entitled to a predetermined fixed portion of profits as outlined in their membership interest participation certificates until such post-termination distributions aggregated to a “target amount” set forth their respective participation certificates. Once the target amount had been reached, their respective rights to share in any future distributions ceased.

On May 9, 2023, the terms of Messrs. Levin’s and Pollock’s membership interests in Holdings were amended (the “Amended Holdings Award Interests”). The Amended Holdings Award Interests entitle the holders to a stated percentage, or minimum allocable share, of distributions from Holdings, as well as a profits interest with respect to net sale proceeds from dispositions of Holdings properties after certain threshold distributions to other members. The amendments to the Original Holdings Award Interests resulted in a change to the accounting treatment of these awards as they now have characteristics that are more akin to the risks and rewards of equity ownership in Holdings. In particular, the Original Holdings Awards Interests were previously recognized under ASC 710, Compensation—Profits Interest, and pursuant to ASC 505. The modifications caused the Amended Holdings Award Interests to be recognized as compensation expense with a corresponding deemed contribution and are now accounted for under ASC 718, Compensation—Stock Compensation. As a result, partnership interest-based compensation expenses taken prior to 2023 associated with the right to received stated “target amounts” as provided in the Original Holdings Award Interests were reversed to reflect that that the stated “target amounts” were removed by the amendment, while partnership interest-based compensation expense associated with the Amended Holdings Award Interests was recorded. The effect of the reversal and recognition of these expenses was to avoid duplicate financial accounting expenses with respect to the same item of compensation. Mr. Levin’s and a portion of Mr. Pollock’s Amended Holdings Award Interests were fully vested on the date of the amendment and resulted in immediate expense recognition for financial accounting purposes. A portion of Mr. Pollock’s Amended Holdings Award Interests vested and was expensed over the requisite service period through December 31, 2024.

For Ms. Buchanan, the discretionary portion of the profits for 2025 is set forth in the “All Other Compensation” column of the Summary Compensation Table above. Ms. Buchanan’s membership interest in Holdings terminated effective September 30, 2025 in connection with her resignation.

For so long as the officers are members of Holdings, and for certain periods after their withdrawal as members, they are subject to restrictive covenants prohibiting disclosure of our confidential information, disparaging our business, and, for two years after withdrawal, from competing with our business or soliciting our clients or employees, subject to exceptions for actions taken in the performance of their duties to us or in connection with the investment or management of the officer’s or his or her family’s assets (or assets belonging to other members and their affiliates and certain charitable, non-profit and government organizations).

Mses. Bentley and Buchanan hold membership interests in Management LLC, an entity controlled by Mr. Sacks, which entitle them to a portion of all profits distributed by Management LLC to its members, but not to proceeds from any capital transaction.

For so long as Mses. Bentley and Buchanan are members of Management LLC, and for certain periods after their withdrawal as a member, they are subject to restrictive covenants prohibiting disclosure of our confidential information, disparaging our business, and, for two years after withdrawal, from competing with our business or soliciting our clients or employees, subject to exceptions for actions taken in the performance of their duties to us or in connection with the investment or management of their or their family’s assets (or assets belonging to other members and their affiliates).

The distributions received by Mses. Bentley and Buchanan in 2025 are set forth in the All Other Compensation column of the Summary Compensation Table above.

In December 2022, Management LLC awarded both Mses. Bentley and Buchanan 300,000 interests in Management LLC that represent the right to receive shares of the Company’s common stock owned by Management LLC, subject to continued employment through May 1, 2025, except in the case of termination of employment due to death or disability, in which case the Management Award Interests remains outstanding, to be settled within 90 days following May 1, 2025 (the “Management Award Interests”). Each of Mses. Bentley and Buchanan elected to defer delivery of their Management Award Interests until May 1, 2030.

For each bonus period commencing on the period ending on the last day of the bonus period in respect of 2025, Mr. Pollock is eligible for a cash bonus in an amount to be determined in the sole discretion of GCMLP provided that his annual cash bonus for each bonus period in respect of calendar years 2023, 2024, and 2025 is at least $1,000,000 for each such bonus period.

Ms. Bentley. Upon Ms. Bentley’s termination from GCMLP other than (i) for cause or (ii) due to her death or disability, Ms. Bentley will receive (a) separation payments in the form of salary continuation payments at the rate of $200,000 and (b) reimbursement of continuation group health insurance premiums for GCMLP’s group health insurance coverage, in each case during the 12-month period following her termination date. Ms. Bentley’s employment agreement also contains customary restrictive covenants, including obligations relating to confidentiality, perpetual non-disparagement and assignment of intellectual property provisions, as well as a one-year post-termination restriction on competition and two-year post-termination restrictions on interference with business relationships and solicitation of employees, clients and marketing agents provisions, subject to certain exceptions set forth in the agreement. If Ms. Bentley materially violates any of these restrictive covenants GCMLP may cease paying any unpaid installments of the separation payment and the post-termination insurance benefits. Ms. Bentley’s entitlement to receive the separation payment is conditioned upon her execution and non-revocation of a separation agreement that includes a general release of claims in the form then in use by GCMLP.

Ms. Buchanan. Ms. Buchanan served as Chief Human Resources Officer of the Company until her resignation, effective October 3, 2025. Ms. Buchanan’s employment agreement contained customary restrictive covenants, including obligations relating to confidentiality, perpetual non-disparagement, and assignment of intellectual property provisions.

In the event of a termination of employment by reason of death or disability, unvested RSUs will be automatically become vested and payment with respect to those RSUs would generally occur within 30-days following such termination. Upon a termination of employment for “cause” all outstanding RSUs, whether vested or unvested will be forfeited and will be subject to a repayment obligation as set forth in our clawback policy. Upon a termination of employment for any other reason, any unvested RSUs will automatically be forfeited.

Carried Interest Plan. In the event of a participating officer’s termination without “cause” (as defined in the applicable governing documents) or resignation, the participating officer will forfeit such officer’s unvested carried interest sharing percentage, and such officer will only participate in future distributions of carried interest based on a carried interest sharing percentage that has been reduced to reflect the relevant forfeiture; provided, that, in connection with Mr. Pollock’s employment agreement described above, in the event Mr. Pollock provides six months’ written notice of his resignation, all unvested carried interest awarded to Mr. Pollock on or prior to March 31, 2022 that is not fully vested as of the termination date will be deemed 80% vested as of such termination date. If a participating officer is terminated for “cause” or otherwise triggers a forfeiture event under the applicable governing documents, such officer will forfeit such officer’s entitlement to any future distributions of carried interest and all such officer’s carried interest sharing percentages shall be reduced to zero. Upon a participating officer’s death or “disability” (as defined in the applicable governing documents), such officer (or such officer’s estate) shall continue to participate in carried interest distributions without any adjustment to such officer’s carried interest sharing percentages.

Deferred Compensation Plan. Upon termination of employment for any reason other than for “cause” (as defined in the plan), the unvested portion of an outstanding award is forfeited. The vested portion will continue to be paid in accordance with the provisions of the plan. Upon a termination for cause or due to the employee’s willful breach of the

plan and award agreement under the plan, employee handbooks or other agreements with GCMLP, Holdings and their affiliates, all awards, vested and unvested, are immediately forfeited.

Management Award Interests. In December 2022, Management LLC awarded each of Mses. Bentley and Buchanan 300,000 Management Award Interests, each representing the right to receive shares of the Company’s common stock owned by Management LLC. The Management Award Interests were subject to continued employment through May 1, 2025, except in the case of a termination due to death or disability, in which case the interests would remain outstanding and be settled within 90 days following May 1, 2025. The Management Award Interests vested on May 1, 2025. Each of Mses. Bentley and Buchanan elected to defer delivery of the shares underlying their Management Award Interests until May 1, 2030.

The following table lists the estimated amounts that would have been payable to our named executive officers that were employed on the last day of our last completed fiscal year under their employment arrangements and outstanding equity awards in connection with a termination that occurred on the last day of our last completed fiscal year and the value of any additional equity that would vest upon such termination, assuming that the applicable triggering event occurred on December 31, 2025, and that the price per share was $11.32, which was the closing price per share of GCMG Class A common stock listed on the Nasdaq on the last trading day of the year. Ms. Buchanan, who resigned effective October 3, 2025, is excluded from the table below, as she did not receive any severance payments in connection with such resignation and was not employed by the Company as of December 31, 2025. Carried interest is paid based on the price at which Grosvenor funds are able to sell or otherwise realize value from their investments; it is inherently uncertain and any yet unrealized carried interest amounts may not be paid for several years after carried interest is fully vested, if at all. Because of this uncertainty we do not provide a calculation of carried interest payment amounts that would be payable following the NEO’s termination on December 31, 2025.

Ms. Buchanan resigned as Managing Director and Chief Human Resources Officer effective October 3, 2025. Ms. Buchanan did not receive any severance payment in connection with her resignation. Consistent with the terms of the applicable award agreements, Ms. Buchanan forfeited all unvested RSU awards as of her departure date. The forfeited awards consisted of 109,193 RSUs with an aggregate grant date fair value of $1,320,025 and a value of $1,308,132 based on the closing price of our Class A common stock on October 3, 2025.

With respect to Ms. Buchanan’s carried interest arrangements, she retains her vested carried interest sharing percentages as of her departure date and will continue to receive distributions attributable to those percentages as and when made under the applicable governing documents. Ms. Buchanan forfeited all unvested carried interest sharing percentages upon resignation.

Ms. Buchanan’s membership interest in Holdings, an entity controlled by Mr. Sacks, terminated effective September 30, 2025 in connection with her resignation. Ms. Buchanan did not receive any distributions from Holdings following September 30, 2025. Ms. Buchanan’s membership interest in Management LLC, an entity controlled by Mr. Sacks, was not terminated upon her resignation. Ms. Buchanan’s Management LLC interest will terminate in connection with the delivery of her Management Award Interests on May 1, 2030. Ms. Buchanan is expected to receive post-departure distributions from Management LLC through that date, the amount of which will be determined in the sole discretion of the managing member.

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 determined that the 2025 total compensation of the median compensated employee among all our employees who were employed as of December 31, 2025, other than Mr. Sacks, our Chief Executive Officer, was $195,091; Mr. Sacks’ 2025 total compensation was $6,265,398; and the ratio of these amounts was approximately 1-to-32.

We identified the median employee using data as of December 31, 2025 by examining base salary, annual cash bonus and value of equity awards for fiscal year 2025 for all employees, excluding our Chief Executive Officer, who were employed by us on December 31, 2025. We included all employees, whether employed on a full-time, part-time, seasonal or temporary basis. We did not make any material assumptions, adjustments or estimates with respect to total compensation, other than, consistent with applicable SEC rules, reasonable estimates in the methodology used for non-U.S. employees. We annualized the compensation for all employees hired during 2025. After identifying the median employee, we calculated annual total compensation for such employee using the same methodology we used for determining the Chief Executive Officer’s compensation shown in the Summary Compensation Table. Because the SEC rules for identifying the median employee and calculating the pay ratio under Item 402(u) of Regulation S-K allow companies to use different methodologies, exemptions, estimates and assumptions, the ratio may or may not be comparable to pay ratios presented by other companies.

In accordance with Item 402(v) of Regulation S-K, the Company is providing the following descriptions of the relationships between the information presented in the table above.

The following table sets forth compensation paid to our non-employee directors for our fiscal year ended December 31, 2025.

Our policy is to not pay director compensation to directors who are also our employees. Our Board has approved the GCM Grosvenor Inc. Non-Employee Director Compensation Policy, which provides for cash and equity-based compensation to those members of our Board who are not employees of us or any of our parents or subsidiaries. Under the policy from January 1, 2025 to March 31, 2025, each non-employee director was entitled to receive an annual director fee of $200,000 as well as additional committee membership/chair fees, as follows: (i) annual fee of $50,000 for service as the chair of our audit committee, (ii) annual fee of $35,000 for service on our audit committee (such that the audit committee chair receives $85,000 in total), (iii) $15,000 for service on any other committee, and (iv) additional $30,000 fee to the chair of any other committee. Under the policy beginning April 1, 2025, the annual director fee is $250,000, the annual fee for service as the chair of our audit committee is $60,000 and the annual fee for service on our audit committee is $45,000 (such that the audit committee chair receives $105,000 total audit committee fees). The fees are earned on a quarterly basis and paid in arrears. They are pro-rated in the event service is for a portion of the quarter. The non-employee directors are eligible to elect to receive director fees in the form of fully vested shares of Class A common stock in lieu of cash, or all or a portion of his or her cash fee in the form of deferred restricted stock units, which will be delivered, at the option of the director, on the earlier of (1) the day immediately preceding the date of the first annual meeting of the Company’s stockholders that is at least 50 weeks from the date of grant, or (2) the first anniversary of the date of grant, the director’s cessation of service due to death or disability (as determined in good faith by the Board), the director’s continued service through the date of a change of control of the Company, the date of the director’s separation of service, or any later fixed date that is permitted by the Company and that complies with Section 409A of the Internal Revenue Code.

Each non-employee director also receives an initial award of 10,000 restricted stock units, which vests in full on the first anniversary of the non-employee director’s start date, subject to the non-employee director continuing in service through such date. The restricted stock units will accelerate and become fully vested in the event of a Change of Control (as defined in the Amended and Restated Incentive Award Plan) or the directors’ termination of service due to death or disability. The policy may be amended, modified or terminated by the Board at any time in its sole discretion.

As a controlled company, we do not have a compensation committee of the Board, or a committee performing equivalent functions. Michael J. Sacks, our Chief Executive Officer, and Jonathan R. Levin, our President, participated in our Board’s deliberations regarding executive officer compensation during the year ended December 31, 2025.

The following table provides information on our equity compensation plans as of December 31, 2025:

The following table sets forth information regarding the beneficial ownership of our voting shares by:

Beneficial ownership is determined according to the rules of the SEC, which generally provide that a person has beneficial ownership of a security if he, she or it possesses sole or shared voting or investment power over that security, including options and warrants that are currently exercisable or exercisable within 60 days. A person is also deemed to be a beneficial owner of any securities of which that person has a right to acquire beneficial ownership within 60 days, provided that any person who acquires any such right with the purpose or effect of changing or influencing the control of the issuer, or in connection with or as a participant in any transaction having such purpose or effect, immediately upon such acquisition shall be deemed to be the beneficial owner of the securities which may be acquired through the exercise of such right. Under these rules, more than one person may be deemed to be a beneficial owner of the same securities.

Our authorized common stock consists of Class A common stock, Class B common stock and Class C common stock. Holders of Class B common stock are not entitled to any voting rights on matters submitted to stockholders for a vote.

Beneficial ownership of shares of our common stock is based on 59,418,170 shares of Class A common stock and 141,665,831 shares of Class C common stock issued and outstanding as of April 10, 2026. There were no shares of Class B common stock outstanding as of April 10, 2026.

Unless otherwise indicated, we believe that all persons named in the table below have sole voting and investment power with respect to all shares of voting shares beneficially owned by them. Except as set forth below, to our knowledge, none of our shares of common stock beneficially owned by any executive officer or director have been pledged as security.

Our Board recognizes the fact that transactions with related persons present a heightened risk of conflicts of interests (or the perception thereof). We have a written policy on transactions with related persons that is in conformity with the requirements for issuers having publicly held common stock that is listed on Nasdaq. Under the policy, our legal team is primarily responsible for developing and implementing processes and procedures to obtain information regarding related persons with respect to potential related person transactions and then determining, based on the facts and circumstances, whether such potential related person transactions do, in fact, constitute related person transactions requiring compliance with the policy. In addition, any potential related person transaction that is proposed to be entered into by the Company must be reported to the Company’s General Counsel, by both the related person and the person at the Company responsible for such potential related person transaction.

If our legal team determines that a transaction or relationship is a related person transaction requiring compliance with the policy, our General Counsel is required to present to the Audit Committee all relevant facts and circumstances relating to the related person transaction. Our Audit Committee must review the relevant facts and circumstances of each related person transaction, including if the transaction is on terms comparable to those that could be obtained in arm’s length dealings with an unrelated third party and the extent of the related person’s interest in the transaction, take into account the conflicts of interest and corporate opportunity provisions of our Code of Business Conduct and Ethics, and either approve or disapprove the related person transaction. If advance Audit Committee approval of a related person transaction requiring the Audit Committee’s approval is not feasible, then the transaction may be preliminarily entered into by management upon prior approval of the transaction by the chair of the Audit Committee, subject to ratification of the transaction by the Audit Committee at the Audit Committee’s next regularly scheduled meeting; provided, that if ratification is not forthcoming, management will make all reasonable efforts to cancel or annul the transaction. If a transaction was not initially recognized as a related person transaction, then upon such recognition the transaction will be presented to the Audit Committee for ratification at the Audit Committee’s next regularly scheduled meeting; provided, that if ratification is not forthcoming, management will make all reasonable efforts to cancel or annul the transaction.

Our management will update the Audit Committee as to any material changes to any approved or ratified related person transaction and will provide a status report at least annually of all then current related person transactions. No director may participate in approval of a related person transaction for which he or she is a related person.

The following are certain transactions, arrangements and relationships with our directors, executive officers and stockholders owning 5% or more of our outstanding common stock, or any member of the immediate family of any of the foregoing persons, since January 1, 2025, other than equity and other compensation, termination, change in control and other arrangements, which are described under “Executive Compensation.”

GCM Grosvenor utilizes the services of an insurance broker (the “Broker”) to procure insurance coverage, including its general commercial package policy, health, workers’ compensation and professional and management liability coverage for its directors and officers. Mr. Malkin, including his immediate family members, has an economic interest in the Broker totaling approximately 35%, an immediate family member of Mr. Helfand’s wife has an economic interest in the Broker totaling approximately 20% and Mr. Sacks’ brother serves as an executive officer of the Broker. During the year ended December 31, 2025, the Broker received commission payments in respect of the GCM Grosvenor insurance coverage in the amount of $0.5 million.

GCM Grosvenor personnel, including Mr. Sacks, make use of aircraft owned by Holdings that has been leased by Holdings to a third-party aviation services company that manages the aircraft (the “Aviation Company”). GCM Grosvenor charters the aircraft from the Aviation Company, and in some instances, leases from and makes direct payments to Holdings, when GCM Grosvenor personnel and their associated parties use the aircraft for business or personal use. During the year ended December 31, 2025, GCM Grosvenor incurred expenses of approximately $3.6 million, in aggregate to the Aviation Company and Holdings.

GCM Grosvenor’s directors and executive officers are permitted to invest their own capital in GCM Grosvenor’s investment funds on a no-fee and no-carry basis. The opportunity to invest in GCM Grosvenor’s investment funds on a no-fee and no-carry basis is also available to all of GCM Grosvenor’s senior professionals and to those employees whom GCM Grosvenor has determined have a status that reasonably permits it to offer them these types of investments in compliance with applicable laws. GCM Grosvenor encourages its eligible professionals to invest in GCM Grosvenor’s investment funds because it believes that such investing further aligns the interests of GCM Grosvenor’s professionals with those of its fund investors and the firm.

During the year ended December 31, 2025, the aggregate investment by GCM Grosvenor’s directors and executive officers (and their family members and investment vehicles) in GCM Grosvenor’s investment funds was approximately $427.0 million, which includes amounts invested in a GCM Grosvenor investment fund on a non-recourse leveraged basis through a feeder vehicle.

During the year ended December 31, 2025, the aggregate investment by Mr. Sacks (including his family members, investment vehicles and Holdings) in GCM Grosvenor’s investment funds was approximately $113.5 million, which includes amounts invested in a GCM Grosvenor investment fund on a non-recourse leveraged basis through a feeder vehicle.

During the year ended December 31, 2025, the aggregate investment by Mr. Levin (including his family members and investment vehicles) in GCM Grosvenor’s investment funds was approximately $17.8 million, which includes amounts invested in a GCM Grosvenor investment fund on a non-recourse leveraged basis through a feeder vehicle.

During the year ended December 31, 2025, the aggregate investment by Mr. Pollock (including his family members and investment vehicles) in GCM Grosvenor’s investment funds was approximately $2.9 million.

During the year ended December 31, 2025, the aggregate investment by Mr. Malkin (including his family members and investment vehicles he manages for his family members) in GCM Grosvenor’s investment funds was approximately $292.7 million, which includes amounts invested in a GCM Grosvenor investment fund on a non-recourse leveraged basis through a feeder vehicle.

Messrs. Sacks, Levin, Pollock and Malkin (and/or their estate planning vehicles and investment vehicles) hold membership interests in Holdings, and Ms. Buchanan held a membership interest in Holdings during 2025 until September 30, 2025.

On April 22, 2025, Sumitomo Mitsui Trust Bank, Limited (“SuMi Trust”) acquired from us 3,752,965 shares of our Class A common stock, which resulted in SuMi Trust beneficially owning more than 5% of our Class A common stock. The shares were purchased at a price of $13.322799 per share, representing the volume-weighted average price of our Class A common stock for the 10 trading days ended March 31, 2025. We have also entered into a strategic partnership with SuMi Trust.

GCM Grosvenor leases (the “Lease”) its principal headquarters in Chicago from 900 North Michigan, LLC, a Delaware limited liability company (the “Landlord”). Mr. Malkin, including his immediate family members, has an economic interest in the Landlord totaling approximately 36% in the aggregate. An immediate family member of Mr. Helfand’s wife has an economic interest in the Landlord totaling approximately 25%. The term of the Lease expires September 30, 2037. The Lease provides for monthly rent and payment of operating expenses on a triple-net basis. During the year ended December 31, 2025, GCM Grosvenor made lease payments of $6.3 million, in satisfaction of its obligations pursuant to the Lease.

GCM Grosvenor subleases a portion of its principal headquarters in Chicago to Holdings at GCM Grosvenor’s cost under its lease. The current term of the sub-lease expires on September 30, 2037 and provides for monthly rent and payment of operating expenses on a triple-net basis. During the year ended December 31, 2025, Holdings made lease payments to GCM Grosvenor of $0.2 million, in satisfaction of its obligations pursuant to the sublease.

GCM Grosvenor currently provides additional office space, office support and administrative services, to various persons who provide services, including personal services, primarily to Holdings and its members, including Michael J. Sacks. Holdings does not pay GCM Grosvenor for this use of space and support services. While GCM Grosvenor does not account for these services in the ordinary course and their value is not readily quantifiable, GCM Grosvenor would estimate the value of these services to be in excess of $120,000 for the year ended December 31, 2025. GCM Grosvenor also pays for certain expenses on behalf of Holdings and its personnel, including insurance and brand management costs, for which it is reimbursed by Holdings. Holdings similarly pays certain expenses on behalf of GCM Grosvenor, for which it is reimbursed.  

Upon consummation of the Business Combination, we entered into the Stockholders’ Agreement with the GCMH Equityholders and GCM V, pursuant to which, among other things, (i) GCM V was granted rights to designate all seven directors for election to our Board (and GCM V and the GCMH Equityholders will vote in favor of such designees) and (ii) GCM V and the GCMH Equityholders agreed to vote their voting shares in favor of any recommendations by our Board. The Stockholders’ Agreement contemplates that our Board will consist of seven directors with the initial chairperson being Michael J. Sacks and also contains certain provisions intended to maintain our qualification as a “controlled company” within the meaning of Nasdaq Listing Rule 5615(c) corporate governance requirements.

Upon consummation of the Business Combination, we entered into the Registration Rights Agreement with the CF Sponsor, the GCMH Equityholders and the PIPE Investors. Pursuant to the Registration Rights Agreement, we agreed to register for resale, pursuant to Rule 415 under the Securities Act, certain shares of our common stock and other equity securities that are held by the parties thereto from time to time.

In connection with the consummation of the Business Combination, we used a portion of our assets to acquire equity interests of GCMH both directly from GCMH and from certain pre-Business Combination equity holders in GCMH. We expect these transactions to result in an increase in our share of the tax basis of the assets of GCM Grosvenor. In addition, as a result of the transactions undertaken in connection with the Business Combination, we expect to receive the benefit of existing tax basis in certain intangible assets of GCM Grosvenor. Further, we may obtain an increase in our share of the tax basis of the assets of GCM Grosvenor when a GCMH Equityholder receives shares of our Class A common stock or cash, as applicable, in connection with an exercise of such GCMH Equityholder’s right to have common units in GCMH redeemed by GCMH or, at our election, exchanged (which we intend to treat as its direct purchase of common units from such GCMH Equityholder for U.S. federal income and other applicable tax purposes, regardless of whether such common units are surrendered by a GCMH Equityholder to GCMH for redemption or sold upon the exercise of our election to have IntermediateCo acquire such common units directly) (such basis increases, together with the basis increases in connection with the purchase of equity interests of GCMH in connection with the Business Combination, the “Basis Adjustments,” and, together with the tax basis in intangible assets referenced above, the “Basis Assets”). The Basis Assets may have the effect of reducing the amounts that we would otherwise pay in the future to various tax authorities. The Basis Assets may also decrease gains (or increase losses) for tax purposes on future dispositions of certain of GCM Grosvenor’s assets. In connection with the transactions described above, we entered into the Tax Receivable Agreement (the “TRA”) with GCMH Equityholders (the GCMH Equityholders and their successors and assigns with respect to the Tax Receivable Agreement, the “TRA Parties”) that provides for the payment by us to the TRA Parties of 85% of the amount of certain tax benefits, if any, that we actually realize, or in some circumstances are deemed to realize, as a result of the various transactions that occurred in connection with the Business Combination or in the future that are described above, including benefits arising from the Basis Assets and certain other tax benefits attributable to payments made under the Tax Receivable Agreement. GCMH intends to have in effect an election under Section 754 of the Internal Revenue Code of 1986, as amended, effective for each taxable year in which a redemption or exchange (including for this purpose the purchase of equity interests of GCMH from certain pre-Business Combination equity holders described above) of Grosvenor common units for Class A common stock or cash occurs. The tax benefit payments provided for under the Tax Receivable Agreement are not conditioned upon one or more of the GCMH Equityholders maintaining a continued ownership interest in GCMH or its affiliates. The GCMH Equityholders rights under the Tax Receivable Agreement are generally assignable.

We have entered into indemnification agreements with each of our directors and executive officers.

Section 16(a) of the Exchange Act requires the Company’s executive officers, directors, and holders of more than 10% of its common stock to file reports of ownership and changes in ownership with the SEC and to furnish us with copies. Based solely on our review of Forms 3, 4, and 5 filed during fiscal 2025, and written representations from reporting persons that no Form 5 was required to report previously unreported transactions, we believe that all Section 16(a) filing obligations applicable to our directors, executive officers, and 10% stockholders were satisfied on a timely basis during fiscal 2025, with the following exceptions: each of Pamela Bentley, Chief Financial Officer, Sandra Buchanan, former Chief Human Resources Officer, and Kathleen Sullivan, Chief Accounting Officer, filed one Form 4 one day late in April 2025 in connection with the settlement and withholding of shares of Class A common stock to satisfy tax obligations upon the vesting of RSUs.

Stockholders who intend to have a proposal considered for inclusion in our proxy materials for presentation at our 2027 Annual Meeting of Stockholders pursuant to Rule 14a-8 under the Exchange Act must submit the proposal to our Secretary at our offices at 900 North Michigan Avenue, Suite 1100, Chicago, Illinois 60611 in writing not later than December 25, 2026.

Stockholders intending to present a proposal at the 2027 Annual Meeting of Stockholders, but not to include the proposal in our proxy statement, or to nominate a person for election as a director, must comply with the requirements set forth in our Bylaws. Our Bylaws require, among other things, that our Secretary receive written notice from the stockholder of record of their intent to present such proposal or nomination not less than 90 days nor more than 120 days prior to the one-year anniversary of the preceding year’s annual meeting. Therefore, we must receive notice of such a proposal or nomination for the 2027 Annual Meeting of Stockholders no earlier than February 9, 2027 and no later than March 11, 2027. The notice must contain the information required by the Bylaws, a copy of which is available upon request to our Secretary. In the event that the date of the 2027 Annual Meeting of Stockholders is more than 30 days before or more than 60 days after June 9, 2027, then our Secretary must receive such written notice not earlier than the close of business on the 120th day prior to the 2027 Annual Meeting and not later than the close of business on the 90th day prior to the 2027 Annual Meeting or, if later, the close of business on 10th day following the day on which public disclosure of the date of such meeting is first made by us. In addition to satisfying the foregoing requirements under the Bylaws, to comply with the universal proxy rules, stockholders who intend to solicit proxies in support of director nominees other than the Company’s nominees must provide notice that sets forth the information required by Rule 14a-19(b) under the Exchange Act.

We reserve the right to reject, rule out of order, or take other appropriate action with respect to any proposal that does not comply with these or other applicable requirements.

Our Board of Directors is not aware of any matter to be presented for action at the Annual Meeting other than the matters referred to above and does not intend to bring any other matters before the Annual Meeting. However, if other matters should come before the Annual Meeting, it is intended that holders of the proxies named on the Company’s proxy card will vote thereon in their discretion.

The accompanying proxy is solicited by and on behalf of our Board of Directors, whose Notice of Annual Meeting is attached to this proxy statement, and the entire cost of our solicitation will be borne by us. In addition to the use of mail, proxies may be solicited by personal interview, telephone, e-mail and facsimile by our directors, officers and other employees who will not be specially compensated for these services. We will also request that brokers, nominees, custodians and other fiduciaries forward soliciting materials to the beneficial owners of shares held by the brokers, nominees, custodians and other fiduciaries. We will reimburse these persons for their reasonable expenses in connection with these activities.

Certain information contained in this proxy statement relating to the occupations and security holdings of our directors and officers is based upon information received from the individual directors and officers.

We intend to file a Proxy Statement and WHITE proxy card with the SEC in connection with the solicitation of proxies for our 2027 Annual Meeting of Stockholders. Stockholders may obtain our Proxy Statement (and any amendments and supplements thereto) and other documents as and when filed by us with the SEC without charge from the SEC’s website at: www.sec.gov.

The following table shows reconciliations of net income attributable to GCM Grosvenor Inc. and Adjusted Pre-Tax Income, Adjusted Net Income and Adjusted EBITDA for the years ended December 31, 2025, 2024 and 2023, respectively:
