Use of Non-GAAP Financial Measures and Key Performance Indicators

This press release includes certain non-GAAP financial measures, including fee-related revenue, fee-related earnings, adjusted pre-tax income, adjusted net income, adjusted EBITDA and net incentive fees attributable to GCM Grosvenor. These non-GAAP measures are in addition to, and not a substitute for or superior to, measures of financial performance prepared in accordance with GAAP, and should not be considered as an alternative to revenue, net income, operating income or any other performance measures derived in accordance with GAAP. Reconciliations of historical non-GAAP measures to their most directly comparable GAAP counterparts are included in below.

GCM Grosvenor believes that these non-GAAP measures of financial results provide useful supplemental information to investors about GCM Grosvenor. GCM Grosvenor’s management uses these non-GAAP

measures to evaluate GCM’s projected financial and operating performance. However, there are a number of limitations related to the use of these non-GAAP measures and their nearest GAAP equivalents. For example other companies may calculate non-GAAP measures differently, or may use other measures to calculate their financial performance, and therefore GCM Grosvenor’s non-GAAP measures may not be directly comparable to similarly titled measures of other companies.

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 Grosvenor Capital Management Holdings, LLLP ("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, (g) unrealized investment income, (h) changes in tax receivable agreement ("TRA") 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. We believe adjusted pre-tax income is useful to investors because it provides additional insight into the operating profitability of our business. Adjusted net income represents adjusted pre-tax income minus adjusted income taxes, which represents corporate income taxes at a blended statutory rate of 24.5% applied to Adjusted Pre-Tax Income for the three and six months ended June 30, 2022 and of 25.0% for the three and six months ended June 30, 2021. The 24.5% and 25.0% are based on a federal statutory rate of 21.0% and a combined state, local and foreign rate net of federal benefits of 3.5% and 4.0%, respectively.

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. We believe Adjusted EBITDA is useful to investors because it enables them to better evaluate the performance of our core business across reporting periods.

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.

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.

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.

Fee-Paying Assets Under Management (“FPAUM”) 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 during or prior to the initial commitment or investment period where fees are expected to be charged in the future based on invested capital (capital committed to underlying investments) or on a scheduled ramp-in of total commitments.
