20 Illustrative Client Economic Value Proposition: Absolute Return Strategies Example: $300M Fee Paying; $300M Non-Fee Paying. Assuming 0% gross return. 30. This hypothetical portfolio has an annual performance fee component of 5% over a hurdle (capped at 5%) of 90-day U.S. T-Bill plus 2%. 31. Fee savings is shown for illustrative purposes only, and is not intended to imply that any GCM Grosvenor portfolio will achieve such savings over any period. Fee savings varies by GCM Grosvenor portfolio and our calculation of fee savings is subject to a number of assumptions. Fee savings may be greater at higher rates of return for certain portfolios. 32. Reflects the weighted-average GCM Grosvenor portfolio-level management fee across the fee-paying and non-fee-paying portions reflected above, assuming a 50/50 AUM split between the two. In practice many large institutional clients have greater than 50% of their absolute return programs being managed on a direct basis and consequently the value of a relationship with GCM Grosvenor is greater.

1. Excludes fund reimbursement revenue of $2.6 million and $3.3 million for the three months ended March 31, 2022 and 2023, respectively. 2. Excludes fund reimbursement revenue for private markets of $1.0 million and $1.6 million for the three months ended March 31, 2022 and 2023, respectively. 3. Excludes fund reimbursement revenue for absolute return strategies of $1.6 million and $1.7 million for the three months ended March 31, 2022 and 2023, respectively. 4. Reflects a corporate and blended statutory tax rate of 24.5% and 24.2% applied to Adjusted Pre-Tax Income for the three months ended March 31, 2022 and 2023. The rate was adjusted from 24.5% to 24.2% in Q4 2022 and therefore Q4 2022 reflects a true-up to bring 2022 expense to 24.2% for the year. The 24.2% and 24.5% are based on a federal statutory rate of 21.0% and a combined state, local and foreign rate net of federal benefits of 3.2% and 3.5%, respectively. 6. Firm share represents net of contractual obligations but before discretionary cash-based incentive compensation. 7. Represents consolidated view, including all NCI and compensation related awards. 8. Run-Rate Annual Performance Fees reflect the potential annual performance fees generated by performance fee-eligible AUM before any loss carryforwards, if applicable, at an 8% gross return for both multi-strategy and credit strategies, and a 10% gross return for specialized opportunity strategies, and before cash-based incentive fee related compensation. 2023 performance fee potential is calculated using the same assumptions as run-rate annual performance fees, but also considers existing loss carryforwards and hurdles if applicable. 9. ESG and Impact Investments AUM as of March 31, 2022 and March 31, 2023. ESG and Impact AUM by Strategy as of March 31, 2023. AUM related to certain ESG and Impact investments includes mark- to-market changes for funds that charge management fees based on commitments. Such increases in AUM do not increase FPAUM or revenue. The data regarding ESG themes presented above and otherwise contained herein is based on the assessment of each such investment by GCM Grosvenor investment team members. The relevant investments are placed into categories that are generally consistent with the categories presented in the UN PRI Impact Investing Market Map. Primary fund assessments are based on whether a significant part of the expected strategy of the primary fund falls into an ESG category. Co-investment categorizations are based either on categories represented by the co-investment sponsor or the underlying portfolio company. Diverse Manager investments include investments managed by or sponsored by a diverse manager, based on GCM Grosvenor’s definition of a diverse manager, which is determined by thresholds of manager economic ownership by diverse parties (race, gender, sexual orientation, veterans, disabled persons). There is significant subjectivity in placing an investment in a particular category, and conventions and methodologies used by GCM Grosvenor in categorizing investments and calculating the data presented may differ from those used by other investment managers. Additional information regarding these conventions and methodologies is available upon request. 10. Based on 25 largest clients by AUM as of March 31, 2023. 11. Based on 50 largest clients by AUM as of March 31, 2023. 12. For Private Markets customized separate accounts from January 1, 2018 through March 31, 2023. 13.

36 Adjusted Net Income is a non-GAAP measure that we present on a pre-tax and after-tax basis to evaluate our profitability. Adjusted Pre-Tax Income represents net income attributable to GCM Grosvenor Inc. including (a) net income (loss) attributable to GCMH, excluding (b) provision (benefit) for income taxes, (c) changes in fair value of derivatives and warrant liabilities, (d) amortization expense, (e) partnership interest-based and non-cash compensation, (f) equity-based compensation, including cash-settled equity awards (as we view the cash settlement as a separate capital transaction), (g) unrealized investment income, (h) changes in tax receivable agreement liability and (i) certain other items that we believe are not indicative of our core performance, including charges related to corporate transactions and employee severance. Adjusted Net Income represents Adjusted Pre-Tax Income fully taxed at each period's blended statutory tax rate. Adjusted Net Income Per Share is a non-GAAP measure that is calculated by dividing Adjusted Net Income by adjusted shares outstanding. Adjusted shares outstanding assumes the hypothetical full exchange of limited partnership interests in GCMH into Class A common stock of GCM Grosvenor Inc., the dilution from outstanding warrants for Class A common stock of GCM Grosvenor Inc. and the dilution from outstanding equity-based compensation. We believe adjusted net income per share is useful to investors because it enables them to better evaluate per-share performance across reporting periods. Adjusted EBITDA is a non-GAAP measure which represents Adjusted Net Income excluding (a) adjusted income taxes, (b) depreciation and amortization expense and (c) interest expense on our outstanding debt. Adjusted EBITDA Margin represents Adjusted EBITDA as a percentage of our total operating revenues, net of fund expense reimbursements. We believe Adjusted Pre-Tax Income, Adjusted Net Income and Adjusted EBITDA are useful to investors because they provide additional insight into the operating profitability of our core business across reporting periods. These measures (1) present a view of the economics of the underlying business as if GCMH Equityholders converted their interests to shares of Class A common stock and (2) adjust for certain non-cash and other activity in order to provide more comparable results of the core business across reporting periods. These measures are used by management in budgeting, forecasting and evaluating operating results. Fee-Related Revenue ("FRR") is a non-GAAP measure used to highlight revenues from recurring management fees and administrative fees. FRR represents total operating revenues less (a) incentive fees and (b) fund reimbursement revenue. We believe FRR is useful to investors because it provides additional insight into our relatively stable management fee base separate from incentive fee revenues, which tend to have greater variability. Fee-Related Earnings (“FRE”) is a non-GAAP measure used to highlight earnings from recurring management fees and administrative fees. FRE represents Adjusted EBITDA further adjusted to exclude (a) incentive fees and related compensation and (b) other non-operating income, and to include depreciation expense. We believe FRE is useful to investors because it provides additional insights into the management fee driven operating profitability of our business. FRE Margin represents FRE as a percentage of our management fee and other operating revenue, net of fund expense reimbursements. Adjusted Revenue represents total operating revenues excluding reimbursement of expenses paid on behalf of GCM Funds and affiliates. Net Incentive Fees Attributable to GCM Grosvenor is a non-GAAP measure used to highlight fees earned from incentive fees that are attributable to GCM Grosvenor. Net incentive fees represent incentive fees excluding (a) incentive fees contractually owed to others and (b) cash-based incentive fee related compensation. Net incentive fees provide investors useful information regarding the amount that such fees contribute to the Company’s earnings and are used by management in making compensation and capital allocation decisions. Certain Definitions and Use of Non-GAAP Financials and Key Performance Indicators

37 Fee-Paying Assets Under Management (“FPAUM” or “Fee-Paying AUM") is a key performance indicator we use to measure the assets from which we earn management fees. Our FPAUM comprises the assets in our customized separate accounts and specialized funds from which we derive management fees. We classify customized separate account revenue as management fees if the client is charged an asset-based fee, which includes the vast majority of our discretionary AUM accounts. The FPAUM for our private market strategies typically represents committed, invested or scheduled capital during the investment period and invested capital following the expiration or termination of the investment period. Substantially all of our private markets strategies funds earn fees based on commitments or net invested capital, which are not affected by market appreciation or depreciation. Our FPAUM for our absolute return strategy is based on net asset value. Our calculations of FPAUM may differ from the calculations of other asset managers, and as a result, this measure may not be comparable to similar measures presented by other asset managers. Our definition of FPAUM is not based on any definition that is set forth in the agreements governing the customized separate accounts or specialized funds that we manage. Contracted, Not Yet Fee-Paying AUM (“CNYFPAUM”) represents limited partner commitments which are expected to be invested and begin charging fees over the ensuing five years. New Capital Raised is new limited partner commitments where fees are charged immediately at the initial commitment date. Assets Under Management (“AUM”) reflects the sum of (a) FPAUM, (b) CNYFPAUM and (c) other mark-to-market, insider capital and non-fee-paying assets under management. GCM Grosvenor refers to the combined accounts of (a) Grosvenor Capital Management Holdings, LLLP ("LLLP" or "GCMH"), an Delaware limited liability limited partnership, and its consolidated subsidiaries and (b) GCM, L.L.C., a Delaware limited liability company. Transaction refers to the business combination announced August 3, 2020 and completed on November 17, 2020 through which CFAC merged with and into GCM Grosvenor Inc., ceasing the separate corporate existence of CFAC with GCM Grosvenor Inc. becoming the surviving corporation. Following the business combination, the financial statements of GCM Grosvenor Inc. will represent a continuation of the financial statements of GCM Grosvenor with the transaction being treated as the equivalent of GCM Grosvenor issuing stock for the net assets of GCM Grosvenor, Inc., accompanied by a recapitalization. CF Finance Acquisition Corp. (“CFAC”) (NASDAQ: CFFA) was a special purpose acquisition company sponsored by Cantor Fitzgerald, a leading global financial services firm. GCM Grosvenor Inc. was incorporated in Delaware as a wholly owned subsidiary of Grosvenor Capital Management Holdings, LLLP, formed for the purpose of completing the Transaction. Pursuant to the Transaction, Grosvenor Capital Management Holdings, LLLP cancelled its shares in GCM Grosvenor Inc. no longer making GCM Grosvenor Inc. a wholly owned subsidiary of Grosvenor Capital Management Holdings, LLLP.

38 Forward-Looking Statements This presentation contains certain forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995, including statements regarding the expected future performance of GCM Grosvenor’s business, including anticipated incremental revenue from fundraising for specialized funds, the expected future performance of GCM Grosvenor's business and the expected benefits of our share repurchase plan. These forward-looking statements generally are identified by the words “believe,” “project,” “expect,” “anticipate,” “estimate,” “intend,” “strategy,” “future,” “opportunity,” “plan,” “may,” “should,” “will,” “would” and similar expressions. Forward-looking statements are predictions, projections and other statements about future events that are based on current expectations and assumptions and, as a result, are subject to risks and uncertainties. These statements are neither promises nor guarantees, but involve known and unknown risks, uncertainties and other important factors that may cause our actual results, performance or achievements to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements, including, but not limited to, the historical performance of our funds may not be indicative of our future results; risks related to redemptions and termination of engagements; the variable nature of our revenues; competition in our industry; effects of domestic and foreign government regulation or compliance failures; operational risks and data security breaches; our ability to deal appropriately with conflicts of interest; market, geopolitical and economic conditions; identification and availability of suitable investment opportunities; risks relating to our internal control over financial reporting; and risks related to our ability to grow AUM and the performance of our investments. You should carefully consider the foregoing factors and the other risks and uncertainties described in the “Risk Factors” sections of the Annual Report on Form 10-K filed by GCM Grosvenor on February 23, 2023 and its other filings from time to time with the U.S. Securities and Exchange Commission. These filings identify and address other important risks and uncertainties that could cause actual events and results to differ materially from those contained in the forward-looking statements. Forward-looking statements speak only as of the date they are made. Readers are cautioned not to put undue reliance on forward-looking statements, and GCM Grosvenor assumes no obligation and does not intend to update or revise these forward-looking statements, whether as a result of new information, future events, or otherwise, except as required by law. Non-GAAP Financial Measures The non-GAAP financial measures contained in this presentation are not GAAP measures of GCM Grosvenor’s financial performance or liquidity and should not be considered as alternatives to net income (loss) as a measure of financial performance or cash flows from operations as measures of liquidity, or any other performance measure derived in accordance with GAAP. A reconciliation of such non-GAAP measures to their most directly comparable GAAP measure is included elsewhere in this presentation. You are encouraged to evaluate each adjustment to non-GAAP financial measures and the reasons management considers it appropriate for supplemental analysis. Our presentation of these measures should not be construed as an inference that our future results will be unaffected by unusual or non-recurring items. In addition, these measures may not be comparable to similarly titled measures used by other companies in our industry or across different industries. This presentation includes certain projections of non-GAAP financial measures including fee-related earnings. Due to the high variability and difficulty in making accurate forecasts and projections of some of the information excluded from these projected measures, together with some of the excluded information not being ascertainable or accessible, GCM Grosvenor is unable to quantify certain amounts that would be required to be included in the most directly comparable GAAP financial measures without unreasonable effort. Consequently, no disclosure of estimated comparable GAAP measures is included and no reconciliation of the forward looking non GAAP financial measures is included. Disclaimer
