GCM GROSVENOR | 33 Data in the presentation is as of March 31, 2024 unless otherwise noted. 1. Of the $7.1 billion CNYFPAUM as of March 31, 2024, approximately $2.3 billion is subject to an agreed upon fee ramp in schedule that will result in management fees being charged on approximately $0.3 billion of such amount in the remainder of 2024, approximately $0.8 billion of such amount in 2025, and remaining approximately $1.2 billion in 2026 and beyond. With respect to approximately $4.8 billion of the $7.1 billion, management fees will be charged as such capital is invested, which will depend on a number of factors, including the availability of eligible investment opportunities. 2. Excludes fund reimbursement revenue. 3. Reflects a corporate and blended statutory tax rate of 24.7% and 24.2% applied to Adjusted Pre-Tax Income for the three months ended March 31, 2024 and 2023, respectively. The rate was adjusted from 24.2% to 24.7% in Q4 2023. The 24.7% and 24.2% are based on a federal statutory rate of 21.0% and a combined state, local and foreign rate net of federal benefits of 3.7% and 3.2%, respectively. 4. Employee data as of April 1, 2024. Individuals with dual responsibilities are counted only once. 5. Sustainable / Impact and Alternative Credit Investments overlap with investments in other strategies. 8. Re-up % for Private Markets customized separate accounts from January 1, 2018 through March 31, 2024. Average years between re-ups and re-up % increase for Private Markets customized separate accounts from January 1, 2018 through March 31, 2024. 9. Average increase on each re-up through December 31, 2023. 12. 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. The majority of run-rate annual performance fees relate to ARS. 13. Sustainable and Impact Investments AUM as of March 31, 2024. AUM related to certain Sustainable 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 sustainable 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 a sustainable 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. 14. Some investments are counted in more than one sustainable category. 15. For Private Markets customized separate accounts from January 1, 2018 through March 31, 2024. 16. Based on 50 largest clients by AUM as of March 31, 2024. 17.

See Appendix for the reconciliations of our non-GAAP financial measures to the most comparable GAAP metric. 25. Excludes severance expenses of $4.6 million, $0.9 million and $0.3 million for the three months ended March 31, 2023, December 31, 2023 and March 31, 2024, respectively. Notes

GCM GROSVENOR | 35 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, employee severance, and office relocation costs. 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. 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

GCM GROSVENOR | 36 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. GCM Grosvenor Inc. is a Delaware corporation listed on the Nasdaq under the symbol "GCMG" NM Not Meaningful LTM Last Twelve Months Certain Definitions and Use of Non-GAAP Financials and Key Performance Indicators (continued)

GCM GROSVENOR | 37 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. Share Repurchase Plan Authorization GCMG’s Board of Directors previously authorized a share repurchase plan, which may be used to repurchase outstanding Class A common stock and warrants in open market transactions, in privately negotiated transactions including with employees or otherwise, as well as to retire (by cash settlement or the payment of tax withholding amounts upon net settlement) equity-based awards granted under the Company’s Amended and Restated 2020 Incentive Award Plan (or any successor equity plan thereto). The Company is not obligated under the terms of plan to repurchase any of its Class A common stock or warrants, and the size and timing of these repurchases will depend on legal requirements, price, market and economic conditions and other factors. The plan has no expiration date and the plan may be suspended or terminated by the Company at any time without prior notice. Any outstanding shares of Class A common stock and any warrants repurchased as part of this plan will be cancelled. In February 2024, GCMG's Board of Directors increased the existing share repurchase authorization by $25 million, from $115 million to $140 million. Disclosures
