To supplement our consolidated financial statements, which are prepared and presented in accordance with generally accepted accounting principles in the United States (“GAAP”), we use the following non-GAAP financial measures: fee revenues, adjusted revenues, adjusted net income (on both a pre-tax and after-tax basis), adjusted net income per share, adjusted weighted-average shares, fee-related earnings, fee-related earnings margin, gross realized performance fees and performance fee-related earnings. We have provided this non-GAAP financial information, which is not calculated or presented in accordance with GAAP, as information supplemental and in addition to the financial measures presented in this earnings release that are calculated and presented in accordance with GAAP. Such non-GAAP financial measures should not be considered superior to, as a substitute for or alternative to, and should be considered in conjunction with, the GAAP financial measures presented in this earnings release. The 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, the non-GAAP financial measures in this earnings release may not be comparable to similarly titled measures used by other companies in our industry or across different industries. For definitions of these non-GAAP measures and reconciliations to applicable GAAP measures, please see the section titled “Non-GAAP Financial Measures: Definitions and Reconciliations.”

(1)Dividends paid, as reported in this table, relate to the preceding quarterly period in which they were earned.

(2)The supplemental cash dividend relates to earnings in respect of our full fiscal years 2023 and 2024, respectively.

(3)Fee revenues, adjusted revenues, FRE, FRE margin, gross realized performance fees, PRE, ANI, adjusted weighted-average shares and ANI per share are non-GAAP measures. See the definitions of these measures and reconciliations to the respective, most comparable GAAP measures under “Non-GAAP Financial Measures: Definitions and Reconciliations.”

(4)Excludes the impact of consolidating the Consolidated Funds. See reconciliation of GAAP measures to adjusted measures that follows.

(5)FRE margin is calculated by dividing FRE by fee revenues.

(6)AUM/AUA reflects final data for the prior period, adjusted for net new client account activity through the period presented. Does not include post-period investment valuation or cash activity. Net asset value (“NAV”) data for underlying investments is as of the prior period, as reported by underlying managers up to the business day occurring on or after 100 days, or 115 days at the fiscal year-end, following the prior period end. When NAV data is not available by the business day occurring on or after 100 days, or 115 days at the fiscal year-end, following the prior period end, such NAVs are adjusted for cash activity following the last available reported NAV.

(1)Reflects amounts attributable to consolidated VIEs for which the Company did not acquire any direct economic interests.

(1)Reflects amounts attributable to consolidated VIEs for which the Company did not acquire any direct economic interests.

Fee revenues represents management and advisory fees, net, including amounts earned from the Consolidated Funds which are eliminated in consolidation. We believe fee revenues is useful to investors because it presents the net amount of management and advisory fee revenues attributable to us.

The table below presents the components of fee revenues.

(1)Reflects the add-back of management and advisory fee revenues for the Consolidated Funds, which have been eliminated in consolidation.

(2)Includes income-based incentive fees from certain funds:

Adjusted revenues represents the components of revenues used in the determination of ANI and comprise fee revenues, adjusted incentive fees and realized carried interest allocations. We believe adjusted revenues is useful to investors because it presents a measure of realized revenues.

The table below shows a reconciliation of revenues to adjusted revenues.

(1)Reflects the add-back of management and advisory fee revenues for the Consolidated Funds, which have been eliminated in consolidation.

(2)Reflects the add back of incentive fees for the Consolidated Funds, which have been eliminated in consolidation.

Adjusted net income, or “ANI,” is a non-GAAP performance measure that we present before the consolidation of StepStone Funds on a pre-tax and after-tax basis used to evaluate profitability. ANI represents the after-tax net realized income attributable to us. ANI does not reflect legacy Greenspring carried interest allocation revenues, legacy Greenspring carried interest-related compensation and legacy Greenspring investment income (loss) as none of the economics are attributable to us. The components of revenues used in the determination of ANI (“adjusted revenues”) comprise fee revenues, adjusted incentive fees and realized carried interest allocations. In addition, ANI excludes: (a) unrealized carried interest allocation revenues and related compensation, (b) unrealized investment income (loss), (c) equity-based compensation for awards granted prior to and in connection with our IPO, profits interests issued by our non-wholly owned subsidiaries, and unrealized mark-to-market changes in the fair value of the profits interests issued in the private wealth subsidiary, (d) amortization of intangibles, (e) net income (loss) attributable to non-controlling interests in our subsidiaries and realized gains attributable to the profits interests issued in the private wealth subsidiary, (f) charges associated with acquisitions and corporate transactions, and (g) certain other items that we believe are not indicative of our core operating performance (as listed in the table below). ANI is fully taxed at our blended statutory rate. We believe ANI and adjusted revenues are useful to investors because they enable investors to evaluate the performance of our business across reporting periods.

Fee-related earnings, or “FRE,” is a non-GAAP performance measure used to monitor our baseline earnings from recurring management and advisory fees. FRE is a component of ANI and comprises fee revenues less adjusted expenses which are operating expenses other than (a) performance fee-related compensation, (b) equity-based compensation for awards granted prior to and in connection with our IPO, profits interests issued by our non-wholly owned subsidiaries, and unrealized mark-to-market changes in the fair value of the profits interests issued in the private wealth subsidiary, (c) amortization of intangibles, (d) charges associated with acquisitions and corporate transactions, and (e) certain other items that we believe are not indicative of our core operating performance (as listed in the table below). FRE is presented before income taxes. We believe FRE is useful to investors because it provides additional insight into the operating profitability of our business and our ability to cover direct base compensation and operating expenses from total fee revenue.

The table below shows a reconciliation of GAAP measures to additional non-GAAP measures. We use the non-GAAP measures presented below as components when calculating FRE and ANI (as defined below). We believe these additional non-GAAP measures are useful to investors in evaluating both the baseline earnings from recurring management and advisory fees, which provide additional insight into the operating profitability of our business, and the after-tax net realized income attributable to us, allowing investors to evaluate the performance of our business. These additional non-GAAP measures remove the impact of Consolidated Funds that we are required to consolidate under GAAP, and certain other items that we believe are not indicative of our core operating performance.

(1)Reflects the add-back of management and advisory fee revenues for the Consolidated Funds, which have been eliminated in consolidation.

(2)Reflects the add back of incentive fee revenues for the Consolidated Funds, which have been eliminated in consolidation, and deferred incentive fees that are not included in GAAP revenues.

(3)Reflects the removal of compensation paid to certain employees as part of an acquisition earn-out and unrealized amounts associated with cash-based incentive awards tracked to the performance of a designated investment fund.

(4)Reflects the removal of equity-based compensation for awards granted prior to and in connection with the IPO, profits interests issued by our non-wholly owned subsidiaries, and unrealized mark-to-market changes in the fair value of the profits interests issued in the private wealth subsidiary.

(5)Reflects the removal of lease remeasurement adjustments, accelerated depreciation of leasehold improvements for changes in lease terms, amortization of intangibles, transaction-related costs, unrealized mark-to-market changes in fair value for contingent consideration obligation and other non-core operating income and expenses.

(6)Reflects the removal of interest income earned by the Consolidated Funds.

(7)Reflects the removal of amounts for Tax Receivable Agreements adjustments recognized as other income (loss), loss associated with payment made in connection with a secondary transaction executed by one of our private wealth funds, gain associated with amounts received as part of negotiations with a third party related to certain corporate matters, loss on sale of subsidiary and the impact of consolidation of the Consolidated Funds.

The table below shows a reconciliation of income (loss) before income tax to ANI and FRE.

(1)Reflects the portion of pre-tax ANI attributable to non-controlling interests in our subsidiaries and realized gains attributable to the profits interests issued in the private wealth subsidiary:

The contribution to pre-tax ANI attributable to non-controlling interests in subsidiaries and profits interests and performance related earnings / other income (loss) attributable to non-controlling interests in subsidiaries and profits interests presented above specifically related to the profits interests issued in the private wealth subsidiary is presented below.

The contribution to pre-tax ANI attributable to non-controlling interests in subsidiaries and performance related earnings / other income (loss) attributable to non-controlling interests in subsidiaries presented above specifically not attributable to the profits interests issued in the private wealth subsidiary is presented below.

(2)Reflects equity-based compensation for awards granted prior to and in connection with the IPO, profits interests issued by our non-wholly owned subsidiaries, and unrealized mark-to-market changes in the fair value of the profits interests issued in the private wealth subsidiary.

(3)Includes (income) expense related to the following non-core operating income and expenses:

(4)Represents corporate income taxes at a blended statutory rate applied to pre-tax ANI:

(5)Excludes the impact of consolidating the Consolidated Funds and includes deferred incentive fees which are not included in GAAP revenues.

(6)Excludes amounts for Tax Receivable Agreements adjustments recognized as other income (loss) ($0.3 million for the three months ended March 31, 2025, $(0.1) million for the three months ended March 31, 2024, and $0.3 million and $(0.3) million in fiscal 2025 and fiscal 2024, respectively), loss associated with payment made in connection with a secondary transaction executed by one of our private wealth funds ($32.5 million for the three months ended March 31, 2025 and in fiscal 2025), gain associated with amounts received as part of negotiations with a third party related to certain corporate matters ($5.3 million in fiscal 2024), and loss on sale of subsidiary ($0.8 million in fiscal 2024).

FRE margin is a non-GAAP performance measure which is calculated by dividing FRE by fee revenues. We believe FRE margin is an important measure of profitability on revenues that are largely recurring by nature. We believe FRE margin is useful to investors because it enables them to better evaluate the operating profitability of our business across periods.

The table below shows a reconciliation of FRE to FRE margin.

Gross realized performance fees represents realized carried interest allocations and adjusted incentive fees. We believe gross realized performance fees is useful to investors because it presents the total performance fees realized by us.

Performance fee-related earnings, or “PRE,” represents gross realized performance fees less realized performance fee-related compensation. We believe PRE is useful to investors because it presents the performance fees attributable to us, net of amounts paid to employees as performance fee-related compensation.

The table below shows a reconciliation of total performance fees to gross realized performance fees and PRE.

(1)Reflects the add back of incentive fee revenues for the Consolidated Funds, which have been eliminated in consolidation.

ANI per share measures our per-share earnings assuming all Class B units, Class C units and Class D units in the Partnership were exchanged for Class A common stock in SSG, including the dilutive impact of outstanding equity-based awards. ANI per share is calculated as ANI divided by adjusted weighted-average shares outstanding. We believe adjusted weighted-average shares and ANI per share are useful to investors because they enable investors to better evaluate per-share operating performance across reporting periods.

The following table shows a reconciliation of diluted weighted-average shares of Class A common stock outstanding to adjusted weighted-average shares outstanding used in the computation of ANI per share.

(1)Assumes the full exchange of Class B units, Class C units or Class D units in the Partnership for Class A common stock of SSG pursuant to the Class B Exchange Agreement, Class C Exchange Agreement or Class D Exchange Agreement, respectively.

We monitor certain operating metrics that are either common to the asset management industry or that we believe provide important data regarding our business. Refer to the Glossary below for a definition of each of these metrics.

(1)Contributions consist of new capital commitments that earn fees on committed capital and capital contributions to funds and accounts that earn fees on net invested capital or NAV.

(2)Distributions consist of returns of capital from funds and accounts that pay fees on net invested capital or NAV and reductions in fee-earning AUM from funds that moved from a committed capital to net invested capital fee basis or from funds and accounts that no longer pay fees.

(3)Market value, FX and other primarily consist of changes in market value appreciation (depreciation) for funds that pay on NAV and the effect of foreign exchange rate changes on non-U.S. dollar denominated commitments. The three months ended March 31, 2025 and year ended March 31, 2025 include a $0.6 billion secondary transaction within focused commingled funds.

Note: Amounts may not sum to total due to rounding. AUM/AUA reflects final data for the prior period, adjusted for net new client account activity through the period presented, and does not include post-period investment valuation or cash activity. Net asset value (“NAV”) data for underlying investments is as of the prior period, as reported by underlying managers up to the business day occurring on or after 100 days, or 115 days at the fiscal year-end, following the prior period end. When NAV data is not available by the business day occurring on or after 100 days, or 115 days at the fiscal year-end, following the prior period end, such NAVs are adjusted for cash activity following the last available reported NAV.

(1)Allocation of AUM by asset class is presented by underlying investment asset classification.

(2)Total capital responsibility equals assets under management (AUM) plus assets under advisement (AUA).

Brian Ruby / Chris Gillick / Matt Lettiero, ICR Assets under advisement, or “AUA,” consists of client assets for which we do not have full discretion to make investment decisions but play a role in advising the client or monitoring their investments.

We generally earn revenue for advisory-related services on a contractual fixed fee basis. Advisory-related services include asset allocation, strategic planning, development of investment policies and guidelines, screening and recommending investments, legal negotiations, monitoring and reporting on investments, and investment manager review and due diligence. Advisory fees vary by client based on the scope of services, investment activity and other factors. Most of our advisory fees are fixed, and therefore, increases or decreases in AUA do not necessarily lead to proportionate changes in revenue. We believe AUA is a useful metric for assessing the relative size of our advisory business.

Our AUA is calculated as the sum of (i) the NAV of client portfolio assets for which we do not have full discretion and (ii) the unfunded commitments of clients to the underlying investments. Our AUA reflects the investment valuations in respect of the underlying investments of our client accounts on a three-month lag, adjusted for new client account activity through the period end. Our AUA does not include post-period investment valuation or cash activity. AUA as of March 31, 2025 reflects final data for the prior period (December 31, 2024), adjusted for net new client account activity through March 31, 2025. NAV data for underlying investments is as of December 31, 2024, as reported by underlying managers up to the business day occurring on or after 115 days following December 31, 2024. When NAV data is not available by the business day occurring on or after 115 days following December 31, 2024, such NAVs are adjusted for cash activity following the last available reported NAV.

Assets under management, or “AUM,” primarily reflects the assets associated with our separately managed accounts (“SMAs”) and focused commingled funds. We classify assets as AUM if we have full discretion over the investment decisions in an account or have responsibility or custody of assets. Although management fees are based on a variety of factors and are not linearly correlated with AUM, we believe AUM is a useful metric for assessing the relative size and scope of our asset management business.

Our AUM is calculated as the sum of (i) the net asset value (“NAV”) of client portfolio assets, including the StepStone Funds and (ii) the unfunded commitments of clients to the underlying investments and the StepStone Funds. Our AUM reflects the investment valuations in respect of the underlying investments of our funds and accounts on a three-month lag, adjusted for new client account activity through the period end. Our AUM does not include post-period investment valuation or cash activity. AUM as of March 31, 2025 reflects final data for the prior period (December 31, 2024), adjusted for net new client account activity through March 31, 2025. NAV data for underlying investments is as of December 31, 2024, as reported by underlying managers up to the business day occurring on or after 115 days following December 31, 2024. When NAV data is not available by the business day occurring on or after 115 days following December 31, 2024, such NAVs are adjusted for cash activity following the last available reported NAV.

Consolidated Funds refer to the StepStone Funds that we are required to consolidate as of the applicable reporting period. We consolidate funds and other entities in which we hold a controlling financial interest.

Consolidated VIEs refer to the variable interest entities that we are required to consolidate as of the applicable reporting period. We consolidate VIEs in which we hold a controlling financial interest.

Fee-earning AUM, or “FEAUM,” reflects the assets from which we earn management fee revenue (i.e., fee basis) and includes assets in our SMAs, focused commingled funds and assets held directly by our clients for which we have fiduciary oversight and are paid fees as the manager of the assets. Our SMAs and focused commingled funds typically pay management fees based on capital commitments, net invested capital and, in certain cases, NAV, depending on the fee terms. Management fees are only marginally affected by market appreciation or depreciation because substantially all of the StepStone Funds pay management fees based on capital commitments or net invested capital. As a result, management fees and FEAUM are not materially affected by changes in market value.

We believe FEAUM is a useful metric in order to assess assets forming the basis of our management fee revenue.

Legacy Greenspring entities refers to certain entities for which the Company, indirectly through its subsidiaries, became the sole and/or managing member in connection with the Greenspring acquisition.

SSG refers solely to StepStone Group Inc., a Delaware corporation, and not to any of its subsidiaries.

StepStone Funds refer to SMAs and focused commingled funds of the Company, including acquired Greenspring funds, for which the Partnership or one of its subsidiaries acts as both investment adviser and general partner or managing member.

The Partnership refers solely to StepStone Group LP, a Delaware limited partnership, and not to any of its subsidiaries.

Total capital responsibility equals AUM plus AUA. AUM includes any accounts for which StepStone Group has full discretion over the investment decisions, has responsibility to arrange or effectuate transactions, or has custody of assets. AUA refers to accounts for which StepStone Group provides advice or consultation but for which the firm does not have discretionary authority, responsibility to arrange or effectuate transactions, or custody of assets.

Undeployed fee-earning capital represents the amount of capital commitments to StepStone Funds that has not yet been invested or considered active but will generate management fee revenue once invested or activated. We believe undeployed fee-earning capital is a useful metric for measuring the amount of capital that we can put to work in the future and thus earn management fee revenue thereon.
