#### NOTICE OF ANNUAL MEETING OF STOCKHOLDERS

1:00 p.m. Eastern Time

www.proxydocs.com/STEP

To Our Stockholders:

We are pleased to invite you to attend the 2025 Annual Meeting of Stockholders of StepStone Group Inc. ("StepStone" or the "Company") on Tuesday, September 9, 2025 at 1:00 p.m., Eastern Time, online via live audio webcast by visiting <u>www.proxydocs.com/STEP</u> (the "Annual Meeting") for the following purposes:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. To elect the nine director nominees named in the proxy statement, each to serve for a one-year term and until his or her successor has been duly elected and qualified, or until his or her earlier death, resignation, removal, retirement or disqualification ("Proposal 1");

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. To ratify the appointment of Ernst & Young LLP as the Company's independent registered public accounting firm for the fiscal year ending March 31, 2026 ("Proposal 2");

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3. To approve, on a non-binding and advisory basis, the compensation of our named executive officers ("Proposal 3" or "Say-on-Pay");

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4. To approve an amendment to the Company's Amended and Restated Certificate of Incorporation to limit the liability of certain officers as permitted by Delaware law ("Proposal 4" or the "Exculpation Amendment Proposal");

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5. To approve amendments to the Company's Amended and Restated Certificate of Incorporation to remove obsolete provisions and make certain other clarifying, technical and conforming changes ("Proposal 5" or the "Clean-Up Amendments Proposal"); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6. To transact any other business that may be properly presented at the Annual Meeting or any adjournment or postponement thereof.

The Company's board of directors has determined to continue holding the Annual Meeting virtually. We believe that this is the right choice for StepStone as it provides expanded stockholder access regardless of the location of the Annual Meeting or resources available to stockholders, may improve communications, and allows the participants to attend the Annual Meeting conveniently from any location.

Stockholders of record as of the close of business on July 15, 2025 are entitled to notice of, and, as described in this paragraph, to vote at, the Annual Meeting, or any adjournment or postponement thereof. Holders of our Class A common stock are entitled to one vote for each share held of record on all matters submitted to a vote of stockholders. Holders of our Class B common stock are currently entitled to five votes for each share held of record on all matters submitted to a vote of stockholders. Holders of our Class A common stock and Class B common stock will vote together as a single class on all matters presented to our stockholders for their vote or approval, except as otherwise required by applicable law.

#### Forward-Looking Statements and Website References
This document includes forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, concerning expectations, beliefs, plans, objectives, goals, strategies, future events or performance and underlying assumptions and other statements that are other than statements of historical fact, including statements regarding our environmental and other sustainability plans and goals. Although we believe that the expectations and assumptions reflected in these statements are reasonable, there can be no assurance that these expectations will prove to be correct. Forward-looking statements are subject to many risks and uncertainties, including the risk factors that we identify in our SEC filings, and actual results may differ materially from the results discussed in such forward-looking statements. We undertake no duty to update publicly any forward-looking statement that we may make, whether as a result of new information, future events or otherwise, except as may be required by applicable law, regulation or other competent legal authority.

#### BOARD OF DIRECTORS AND CORPORATE GOVERNANCE

#### Status as a Controlled Company
As of June 30, 2025, holders of our Class B common stock control approximately 61.8% of the voting power of our outstanding common stock because each share of our Class B common stock entitles its holder to five votes on all matters to be voted on by stockholders generally until a Sunset (as defined below) becomes effective. After a Sunset becomes effective, each share of our Class B common stock will entitle its holder to one vote. So long as no Sunset has occurred and the Class B stockholders who are party to the Amended and Restated Stockholders Agreement, dated as of September 20, 2021, by and among the Company, StepStone Group LP, a Delaware limited partnership (the "Partnership") and the other persons and entities party thereto (as the same may be amended and/or restated from time, the "Stockholders Agreement") hold at least approximately 16.7% of all of the outstanding shares of the Company's common stock, the Class B stockholders are expected to hold a majority of the Company's outstanding voting power and thereby will control the outcome of matters submitted to a stockholder vote. A "Sunset" is triggered upon the earliest to occur of the following: (i) Monte Brem, Scott Hart, Jason Ment, Jose Fernandez, Johnny Randel (our former Chief Financial Officer), Michael McCabe, Mark Maruszewski, Thomas Keck, Thomas Bradley, David Jeffrey and Darren Friedman (including their respective family trusts and any other permitted transferees, the "Sunset Holders") collectively cease to maintain direct or indirect beneficial ownership of at least 10% of the outstanding shares of Class A common stock (determined assuming all outstanding Class B units have been exchanged for Class A common stock); (ii) the Sunset Holders cease collectively to maintain direct or indirect beneficial ownership of an aggregate of at least 25% of the aggregate voting power of our outstanding Class A common stock and Class B common stock, before giving effect to a Sunset; and (iii) September 18, 2025. In the case of a Sunset triggered by an event described in clause (i) or (ii) above, a Sunset triggered during the first two fiscal quarters of any fiscal year would have become effective at the end of that fiscal year, and a Sunset triggered during the third or fourth fiscal quarters of any fiscal year would have become effective at the end of the following fiscal year. Given that the Sunset has not been triggered as of the date of this proxy statement, the Sunset will occur on September 18, 2025.

As a result of the voting power currently held by those Class B and Class A stockholders who are party to the Stockholders Agreement, we currently qualify as a "controlled company" within the meaning of the corporate governance rules of The Nasdaq Global Select Market LLC ("Nasdaq"). Under these rules, a listed company of which more than 50% of the voting power with respect to the election of directors is held by an individual, group or another company is a "controlled company" and may elect not to comply with certain corporate governance requirements. Consistent with this, we have elected not to comply with certain corporate governance requirements, including the requirement that (i) a majority of our board of directors consist of independent directors, (ii) director nominees be selected or recommended to the board entirely by independent directors and (iii) the compensation committee be composed entirely of independent directors.

However, when the Sunset occurs on September 18, 2025, we will no longer qualify as a "controlled company" within the meaning of the Nasdaq rules. The Company is preparing to take all action necessary to comply with the Nasdaq rules that apply to non-controlled companies, including transitioning our board of directors (our "board" or our "board of directors") to being composed of a majority of independent directors by September 18, 2026 (the end of the permitted "phase-in" period following loss of controlled company status under the Nasdaq rules). Additionally, as noted below, as of September 18, 2025, our Compensation Committee and Nominating and Corporate Governance Committee will each consist of a majority of independent directors, and on or before September 18, 2026, our Compensation Committee and Nominating and Corporate Governance Committee will each be composed entirely of independent directors, in compliance with the permitted "phase-in" periods under the Nasdaq rules.

#### Composition of our Board of Directors
Our business and affairs are managed under the direction of our board of directors. Our amended and restated certificate of incorporation provides that the size of our board of directors may be set from time to time

------

##### [**Table of Contents**](#toc)
by our then current board of directors. Our board of directors currently consists of 9 members with Mr. Brem serving as Chairperson of our board of directors.

Our amended and restated certificate of incorporation and bylaws originally classified our board of directors into three classes of directors, serving staggered three-year terms of office, subject a sunset that we began implementing starting with our 2023 Annual Meeting of Stockholders. As a result, beginning with this Annual Meeting, all of our directors are standing for annual elections for a one-year term expiring at the 2026 Annual Meeting of Stockholders and until their respective successors are elected and qualified.

Pursuant to the Stockholders Agreement described under "Related Person Transactions—Transactions in Connection with our Reorganization and Initial Public Offering—Stockholders Agreement," certain Class A stockholders, Class B stockholders and Class C unitholders have entered into a Stockholders Agreement pursuant to which they agreed to vote all their shares of voting stock, including Class A common stock and Class B common stock, together and in accordance with the instructions of the Class B Committee (as defined in the Stockholders Agreement), including with respect to nominations for director. The Stockholders Agreement will expire on September 18, 2025.

The following table sets forth information with respect to our directors as of the record date:

---

| | | | |
|:---|:---|:---|:---|
| **Name** | **Age** | **Director<br>Since** | **Position at the Company** |

#### Director Independence
Our Nominating and Corporate Governance Committee and our board have conducted their annual review of the independence of each director nominee under the applicable Nasdaq and SEC independence standards. Based upon the Nominating and Corporate Governance Committee's recommendation and our board's own review and assessment, our board has affirmatively determined in its business judgment that each of Valerie G. Brown, David F. Hoffmeister and Anne L. Raymond is "independent" as defined under the Nasdaq rules and Rule 10A-3 under the Securities and Exchange Act of 1934, as amended (the "Exchange Act").

#### Board Leadership Structure
Our board does not have a policy on whether the role of Chairperson and Chief Executive Officer should be separate or combined and annually reviews its leadership structure to evaluate whether the structure remains appropriate for the Company. After careful consideration, the board determined that, at this time, having separate Chief Executive Officer and Chairperson roles is best for us and our stockholders. As our Chief Executive Officer, Mr. Hart is responsible for developing and overseeing the implementation of our business strategy as well as leading and managing the day-to-day operations of the Company. With Mr. Brem serving as Chairperson of our board of directors, the Company continues to leverage Mr. Brem's experience and history with the Company. In Mr. Brem's role as Chairperson of our board of directors, Mr. Brem focuses on board oversight and governance matters and serves as the liaison between the board and management, working closely with our directors and our Chief Executive Officer. In addition, since August 1, 2023, Mr. Brem has served as Executive Advisor to the Company providing such consulting services, as reasonably requested by the board and our Chief Executive Officer. Our board believes that our existing board leadership structure provides the most effective and efficient leadership for the Company at this time. The board recognizes that no single leadership model is right for all companies and at all times and will continue to evaluate whether to split or combine the roles to ensure our leadership structure continues to be in the best interests of the Company and our stockholders.

#### Executive Sessions
In order to promote open discussion among independent directors, our board holds executive sessions of independent directors at least quarterly. These executive sessions are chaired by an independent director selected by the independent directors during such sessions.

#### Board Qualifications & Composition
The Nominating and Corporate Governance Committee periodically reviews, and recommends to our board, the skills, experience, characteristics and other criteria for identifying and evaluating directors. Our board expects directors to be open and forthright, to develop a deep understanding of the Company's business, and to exercise sound judgment and courage in fulfilling their oversight responsibilities. Directors should embrace the Company's values and culture and should possess the highest levels of integrity.

The Nominating and Corporate Governance Committee evaluates the composition of our board annually to assess whether the skills, experience, characteristics and other criteria established by our board are currently represented on our board as a whole, and in individual directors, and to assess the criteria that may be needed in the future in light of the Company's anticipated needs. Our board of directors and the Nominating and Corporate

------

##### [**Table of Contents**](#toc)
Governance Committee also actively seek to achieve a spectrum of perspectives, viewpoints, backgrounds and experiences on the board. Currently, of our nine director nominees, two are women, seven are men, one is two or more races or ethnicities (white and Native American), one is Hispanic or Latino, and seven are white.

The Nominating and Corporate Governance Committee reviews the qualifications of director candidates and incumbent directors in light of the criteria approved by our board and recommends the Company's candidates to our board for election by the Company's stockholders at the applicable annual meeting. We also assess qualifications, experience and backgrounds of our directors as part of our board's annual self-evaluation process. We believe our board is well positioned to provide effective oversight and strategic advice to our management.

#### Procedures for Recommending Individuals to Serve as Directors
The Nominating and Corporate Governance Committee also considers director candidates recommended by our stockholders. Any stockholder who wishes to propose director nominees for consideration by our Nominating and Corporate Governance Committee, but does not wish to present such proposal at an annual meeting of stockholders, may do so at any time by sending each proposed nominee's name and a description of his or her qualifications for board membership to the chair of the Nominating and Corporate Governance Committee by sending an email to <u>shareholders@stepstonegroup.com</u> or in writing, c/o our Chief Legal Officer & Secretary, at StepStone Group Inc., 277 Park Avenue, 45th Floor, New York, New York 10172. The recommendation should contain all of the information regarding the nominee required under the "advance notice" provisions of our amended and restated bylaws ("bylaws") (which can be provided free of charge upon request by writing to our Chief Legal Officer & Secretary at the address listed above). The Nominating and Corporate Governance Committee evaluates nominee proposals submitted by stockholders in the same manner in which it evaluates other director nominees.

#### Committees of the Board of Directors
Our board established an Audit Committee, a Compensation Committee and a Nominating and Corporate Governance Committee. These committees are each described below. Each of our board's committees acts under a written charter, which was adopted and approved by our board of directors. Copies of the committees' charters are available on our website at <u>https://shareholders.stepstonegroup.com/corporate-governance</u>.

#### Committee Membership; Meetings and Attendance
Between April 1, 2024 and March 31, 2025:

• our board of directors held seven meetings;

• our Audit Committee held four meetings;

• our Compensation Committee held four meetings; and

• our Nominating and Corporate Governance Committee held three meetings.

Each of our incumbent directors attended at least 75% of the meetings of our board of directors and the respective committees of which he or she was a member held during the period such incumbent director was a director during the fiscal year ended March 31, 2025 ("fiscal 2025").

Directors are expected to attend the Annual Meeting absent unusual circumstances. Eight out of the nine directors then serving attended the 2024 Annual Meeting of Stockholders.

Effective as of September 18, 2025, the membership of our Compensation Committee and Nominating and Corporate Governance Committee will change to begin transitioning to non-controlled company status to comply

AC: Audit Committee CC: Compensation Committee NCGC: Nominating and Corporate Governance Committee M – Member C – Chairperson

\* Independent Director and Audit Committee Financial Expert

#### Audit Committee
Our Audit Committee consists of Ms. Brown, Mr. Hoffmeister and Ms. Raymond. Mr. Hoffmeister serves as the chair of the Audit Committee. Each of Ms. Brown, Mr. Hoffmeister and Ms. Raymond qualifies as an "independent" director for purposes of the SEC and Nasdaq independence rules that are applicable to audit committee members. Each of Ms. Brown, Mr. Hoffmeister and Ms. Raymond qualifies as an "audit committee financial expert" as defined by the SEC. Our Audit Committee, among other things, has responsibility for:

• appointing, determining the compensation of and overseeing the work of our independent registered public accounting firm, as well as evaluating its independence and performance;

• considering and approving, in advance, all audit and non-audit services to be performed by our independent registered public accounting firm;

• reviewing and discussing with management and the independent auditor, as appropriate, the adequacy and effectiveness of our internal control over financial reporting and our disclosure controls and procedures;

• discussing with management our risk assessment and risk management policies and processes; and

• establishing procedures for the receipt and treatment of complaints and employee concerns regarding our financial statements and auditing process.

#### Compensation Committee
Our Compensation Committee consists of Messrs. Brem and Hart. Mr. Brem serves as the chair of the Compensation Committee. As a controlled company, we rely upon the exemption from the Nasdaq requirement that we have a compensation committee composed entirely of independent directors. As of September 18, 2025, when we are no longer a controlled company, our Compensation Committee will consist of a majority independent directors in order to comply with the applicable Nasdaq rules, as noted above. Our Compensation Committee, among other things, has responsibility for:

• making recommendations to our board of directors with respect to the compensation of the Chief Executive Officer;

• reviewing and approving the compensation of other executive officers;

------

##### [**Table of Contents**](#toc)
• recommending the amount and form of non-employee director compensation; and

• appointing and overseeing any compensation consultant.

#### Nominating and Governance Committee
Our Nominating and Corporate Governance Committee consists of Messrs. Brem and Hart. Mr. Hart serves as the chair of the Nominating and Corporate Governance Committee. As a controlled company, we rely upon the exemption from the Nasdaq requirement that we have a nominating and corporate governance committee composed entirely of independent directors or that our director nominees be otherwise selected or recommended to the board by independent directors. Effective as of September 18, 2025, our Nominating and Corporate Governance Committee will consist of a majority independent directors in order to comply with the applicable Nasdaq rules, as noted above. Our Nominating and Corporate Governance Committee, among other things, has responsibility for:

• identifying individuals qualified to become members of our board of directors, consistent with criteria approved by our board of directors; and

• developing and recommending to our board of directors a set of corporate governance guidelines and principles.

#### Risk Oversight
Our board of directors believes that effective risk management and control processes are critical to StepStone's safety and soundness, our ability to predict and manage the challenges that StepStone may face and, ultimately, StepStone's long-term corporate success.

In general, management is responsible for the day-to-day oversight and management of strategic, operational, legal, compliance, cybersecurity and financial risks, while our board of directors, as a whole and through its committees, is responsible for the oversight of our risk management framework. Consistent with this approach, management reviews both the framework and certain specific risks with our board and Audit Committee at regular board and Audit Committee meetings as part of management presentations that focus on particular business functions, operations, or strategies, and presents steps taken by management to eliminate or mitigate such risks. While our board is ultimately responsible for the risk oversight of our Company, our Audit Committee has primary responsibility for management and mitigation of the risks facing our Company, including major financial, cybersecurity and control risks, and oversight of the measures initiated by management to monitor and control such risks.

Our Audit Committee also monitors compliance with legal and regulatory requirements and considers and approves or disapproves any related person transactions. Our Compensation Committee has responsibility to review the risks arising from our compensation policies and practices applicable to all employees and evaluate policies and practices that could mitigate any such risk. Our Nominating and Corporate Governance Committee has responsibility to review risks relating to our corporate governance practices. These committees provide regular reports on our risk management practices to our full board, as necessary. Our board believes that the Company's current leadership structure supports its risk oversight function.

#### Communications with Directors
Stockholders and other interested parties who wish to communicate with our board or any individual director may do so by sending an email to <u>shareholders@stepstonegroup.com</u> or in writing, c/o our Chief Legal Officer & Secretary, at StepStone Group Inc., 277 Park Avenue, 45th Floor, New York, New York 10172. Communications we receive that relate to accounting, internal accounting controls, auditing matters or securities law matters will be referred to the Audit Committee unless the communication is directed otherwise. You may

------

##### [**Table of Contents**](#toc)
communicate anonymously and/or confidentially. Each communication will be reviewed by our Chief Legal Officer & Secretary to determine whether it is appropriate for presentation to our board or the applicable director(s). The purpose of this screening is to allow our board (or the applicable individual director(s)) to avoid having to consider irrelevant or inappropriate communications (such as advertisements, solicitations, product inquiries or any offensive or otherwise inappropriate materials).

#### Code of Business Conduct and Ethics
Our board adopted a Code of Conduct and Ethics (the "Code") relating to the conduct of our business by all of our employees, executive officers (including our principal executive officers, principal financial officer and principal accounting officer (or persons performing similar functions)), and directors. This Code satisfies the requirement that we have a "code of conduct" under the Nasdaq and SEC rules and is available on our website at <u>https://shareholders.stepstonegroup.com/corporate-governance</u>. To the extent required under the listing rules and SEC rules, we intend to disclose future amendments to certain provisions of this Code, or waivers of such provisions, applicable to any of our executive officers or directors, on our website identified above.

#### Corporate Governance Guidelines
Our board also adopted principles of corporate governance to formalize its governance practices, which serve as a framework within which our board of directors and its committees operate. These principles cover a number of areas, including the role of our board of directors, board composition and leadership structure, director independence, director selection, qualification and election, director compensation, executive sessions, Chief Executive Officer evaluations, succession planning, annual board assessments, board committees, director orientation and continuing education, stockholder engagement and others. A copy of our corporate governance guidelines is available on our website at <u>https://shareholders.stepstonegroup.com/corporate-governance</u>.

#### Compensation Committee Interlocks and Insider Participation
Messrs. Brem and Hart were members of our Compensation Committee during fiscal 2025. Mr. Hart is an executive officer of the Company and Mr. Brem was a non-employee Chairperson of the board, effective August 1, 2023. Previously, Mr. Brem was the Executive Chairman. None of our executive officers currently serves, or has served during the last completed fiscal year, as a member of the board of directors or compensation committee (or other committee performing equivalent functions) of any other entity that has one or more executive officers serving on our board of directors or compensation committee.

#### Insider Trading Policy and Prohibitions and Restrictions on Hedging and Pledging Transactions
Our Insider Trading Policy governs the purchase, sale, and/or any other dispositions of our securities by directors, officers, employees and other covered persons and is designed to promote compliance with insider trading laws, rules and regulations, and listing standards applicable to the Company. To the extent the Company engages in transactions in its securities, it does so in accordance with applicable laws.

Among other things, our Insider Trading Policy prohibits our (i) directors and officers and members of their immediate families and households and their controlled entities (i.e., corporations or other business entities controlled or managed by any such person, and trusts or other entities for which any such person is the trustee or in which any such person has a beneficial pecuniary interest) as well as, (ii) subject to their ability to request an exemption in limited circumstances (1) the Chief Compliance Officer, the Global Head of Human Resources, the Head of Tax and the Head of Fund Accounting, (2) partners and other personnel more likely to be in possession of material non-public information, (3) certain personnel regularly involved in the preparation or review of the Company's financial statements and (4) certain other employees who are so designated from time to time, as well as in the case of clauses (1) – (4), members of their immediate families and households and their controlled entities, from purchasing financial instruments (including, but not limited to, prepaid variable forward contracts, equity swaps, collars, and exchange funds) and from otherwise engaging in transactions that hedge or offset, or are designed to hedge or offset, any decrease in the market value of StepStone securities granted to any such person by us as part of such person's compensation or held, directly or indirectly, by such person. Similarly, persons listed in clause (i) and, subject to their ability to request an exemption in limited circumstances, persons listed in clause (ii) are also prohibited from pledging StepStone securities as collateral for a loan. Our Insider Trading Policy is filed as exhibit 19.1 to our Annual Report on Form 10-K for the year ended March 31, 2025 which was filed with the SEC on May 23, 2025.

Fiscal 2025 Director Compensation

Our policy is to pay director compensation only to directors whom we deem independent. We have adopted a program for compensating our independent directors with a combination of cash and equity.

Annual Retainer. During fiscal 2025 and for fiscal 2026 prior to the Annual Meeting, all independent directors were eligible to receive a $175,000 annual retainer. After the Annual Meeting, the annual retainer for all independent directors will be increased to $200,000. All annual retainers are pro-rated for any partial year of service. Fifty percent of the annual retainer is payable in the form of restricted stock units ("RSUs") and the remaining fifty percent is payable, at the election of such director, in the form of cash or RSUs.

Audit Committee Chair Retainer. In addition to the annual retainer, the chair of the Audit Committee is eligible to receive an additional $25,000 annual retainer. Fifty percent of such retainer is payable in the form of RSUs and the remaining fifty percent is payable, at the election of the director, in the form of cash or RSUs.

RSUs. All RSUs granted to directors vest in full based on continuous service as a member of the board of directors through the earlier of 12 months following the date of grant and the date of our next annual meeting of stockholders.

All members of the board of directors are reimbursed for reasonable costs and expenses incurred in attending meetings of our board of directors.

##### [**Table of Contents**](#toc)
The table below describes the compensation provided to our non-executive officer directors in fiscal 2025. The table excludes Messrs. Fernandez, McCabe and Hart because they each served as executive officers during fiscal 2025 but did not receive separate compensation for their additional service as directors during that time period. In accordance with the director compensation program, the board of directors approved the RSU grants to each independent director with a grant date of September 10, 2024.

(1) Amounts in this column represent the aggregate grant date fair value of RSUs granted during fiscal 2025, calculated in accordance with FASB ASC Topic 718 based on the closing price per share of Class A common stock on the applicable date of grant: (i) for each director other than Mr. Keck, September 10, 2024 of $50.93 and (ii) for Mr. Keck, March 14, 2025 of $53.67. For additional information regarding the assumptions underlying this calculation, please read Note 10 to our consolidated financial statements for the fiscal year ended March 31, 2025 located in our Annual Report on Form 10-K for such fiscal year. As of March 31, 2025, each non-executive director held the following unvested RSUs: Mr. Brem: 0; Ms. Brown: 3,436; Mr. Hoffmeister: 3,926; Mr. Keck: 11,676; Mr. Mitchell: 0; and Ms. Raymond: 3,436.

(2) Mr. Brem is a retired partner of the Partnership, and thus, is not eligible for compensation under our director compensation program. The amounts reported in this table represent the compensation he received from the Partnership for fiscal 2025 and excludes any distributions received in respect of his equity ownership interests in the Partnership. Mr. Brem, MMAR HNL, LLC and the Company are parties to a consulting agreement, pursuant to which Mr. Brem serves as Executive Advisor, providing consulting services as reasonably requested by the board and/or the Chief Executive Officer of the Partnership and the Company, in exchange for which he receives cash consulting fees of $250,000 per year, payable in monthly installments.

(3) Consists of $250,000 in consulting fees and cash payments received in respect of carried interest allocations of $2,494,268.

(4) Ms. Brown, Mr. Hoffmeister and Ms. Raymond elected to receive 100% of their annual retainers in the form of RSUs. The number of RSUs granted was determined based on the closing price per share of Class A common stock on September 10, 2024 of $50.93, rounded down to the next whole share.

(5) Mr. Keck is a partner of the Partnership, and thus, is not eligible for compensation under our director compensation program. The amounts reported in this table represent the compensation he received from the Partnership for fiscal 2025 and excludes any distributions received in respect of his equity ownership interests in the Partnership. The number of RSUs granted to him as an employee was determined based on the closing price per share of Class A common stock on March 14, 2025 of $53.67, rounded to the next whole share. In addition, during fiscal 2025, we adopted the StepStone Group LP Evergreen Fund Incentive Plan, under which we may grant share unit ("Evergreen Fund Units") awards which are similar to RSU awards but entitle the holder to receive shares of SPRIM or StepStone Private Infrastructure Fund Class I Shares, or the cash value thereof, following vesting. Mr. Keck received 1,162 Evergreen Fund Units of SPRIM during fiscal 2025 which vest in four annual installments through February 14, 2029. As the Evergreen Fund Units are not subject to FASB ASC Topic 718, the value received by Mr. Keck upon vesting of the Evergreen Fund Units will be reported in the year in which vesting occurs.

(6) Consists of $500,000 in salary, $577,500 in total cash bonuses for fiscal 2025, cash payments received in respect of carried interest allocations and incentive fee payments of $2,894,399, life and disability insurance premiums of $9,407 and 401(k) company contributions of $8,698.

(7) Mr. Mitchell is not eligible for compensation under our director compensation program and did not receive any compensation from us during fiscal 2025.

Each nominee was appointed to our board prior to or in connection with our initial public offering.

Each director is elected by a plurality of the votes cast. "Plurality" means that the five nominees who receive the largest number of votes cast "For" such nominees are elected as directors. Stockholders may vote "For" any or all of the nominees or "Withhold" with respect any or all of the nominees named in this Proposal 1. Any shares voted "Withhold" and broker non-votes, if any, are not considered votes cast for the foregoing purpose and will have no effect on the outcome of the election.

#### Compensation Philosophy and Determination Process
Executive compensation at StepStone is aligned with both Company and individual performance. The foundation of our executive compensation is in our performance-based compensation culture, which extends far beyond our executive team. To ensure that all levels of our compensation program remain performance-based, we rely heavily on equity ownership and carried interest awards, creating direct links between the compensation realized by our NEOs and the interests of our shareholders and our clients.

In order to attract, retain, reward and motivate talented executives, our executive compensation program consists of the following components:

• annual base salary;

• annual incentive compensation in the form of cash bonuses;

• long-term incentive compensation in the form of RSUs, Evergreen Fund Units, and carried interest awards; and

• retirement, health and welfare benefits, including participation in plans that are generally available to all of our employees.

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 StepStone and enhanced shareholder value.

The compensation of our NEOs is determined by our Compensation Committee, with the compensation for Mr. Hart being subject to recommendation from the Compensation Committee for final determination by the board of directors. Our Compensation Committee did not engage a compensation consultant during fiscal 2025. The Company engaged Johnson Associates as a compensation consultant during fiscal 2025 to provide the Company with market data, analysis and commentary regarding market conditions and compensation trends. In making its determinations and recommendations for fiscal 2025, the Compensation Committee utilized this market information to evaluate the pay mix and structure of our executive compensation.

We value the opinions of our shareholders regarding our executive compensation policies and practices. At the 2024 annual meeting of stockholders, approximately 99% of the votes cast in our say-on-pay advisory vote were in favor of our executive compensation policies and practices. As such, we did not make any changes to our executive compensation program in specific response to the say-on-pay advisory vote.

The Compensation Committee undertakes an annual review of the Company's compensation policies and practices generally, financial incentive criteria, usage of equity for compensation, vesting and performance

criteria and forfeiture and recoupment provisions. The Compensation Committee has determined that risks arising from the Company's compensation policies and practices for all employees are not reasonably likely to have a material adverse effect on the Company.

#### Elements of Compensation
In order to attract, retain, motivate and reward our executives, we consider a total rewards approach to compensation, which consists of the components described below.

#### Base Salary
The base salary for each of the NEOs is determined by the Compensation Committee (or, for Mr. Hart, by recommendation from the Compensation Committee to the board of directors for approval). For fiscal 2025, the Compensation Committee (or, for Mr. Hart, the board of directors after recommendation from the Compensation Committee) determined to maintain the salary of each NEO at $500,000 annually.

#### Annual Incentive Compensation
For fiscal 2025, Mr. Hart's annual incentive compensation was based on performance against corporate goals and objectives established at the beginning of fiscal 2025 relating to (i) financial performance, including fee-earning assets under management ("FEAUM"), management and advisory fees, fee-related earnings ("FRE"), FRE margin and adjusted net income per share, (ii) team and culture management, including with a view to employee satisfaction, turnover rate, and succession planning considerations, (iii) client relationship management, and (iv) enumerated strategic priorities for fiscal 2025, including progress of fundraising and deployment, including in respect of our evergreen funds, utilization of technology and data, and further development of the Company's business development function and client relationships. Based on a holistic assessment of these goals and objectives, the Compensation Committee recommended and the board of directors approved Mr. Hart's bonus for fiscal 2025 as set forth below.

The other NEOs were eligible to receive an annual bonus for fiscal 2025 based on the approval of the Compensation Committee. In March 2025, in consideration of each NEO's performance and StepStone's performance during fiscal 2025, the Compensation Committee approved bonuses as set forth below.

A portion of each NEO's annual bonus for fiscal 2025 was payable in cash and a portion was paid in the form of equity incentives based on a pre-determined formula derived from each NEO's total compensation. See below under "—Long-Term Incentive Compensation" for more information about such equity incentive awards.

#### Long-Term Incentive Compensation
*Restricted Stock Units*. During fiscal 2025, we granted RSU awards under our 2020 Long-Term Incentive Plan (the "2020 LTIP") to each of our NEOs, with the value of the grants determined as described above under "—Annual Incentive Compensation," with RSU grants representing 80% of each NEO's total equity incentive award. Determining each NEO's RSU award based on the annual bonus goals and objectives (for Mr. Hart) and

------

##### [**Table of Contents**](#toc)
the Compensation Committee's assessment of each NEO's performance and StepStone's performance (for the other NEOs) is intended to align StepStone's executive compensation program with market-based compensation practices, rather than focusing solely on the individual NEO's total ownership level.

*Evergreen Fund Units*. During fiscal 2025, we adopted the StepStone Group LP Evergreen Fund Incentive Plan (the "Evergreen Plan"), under which we may grant Evergreen Fund Unit awards. Evergreen Fund Unit awards are similar to RSU awards but entitle the holder to receive shares of SPRIM or StepStone Private Infrastructure Fund Class I Shares, or the cash value thereof, subject to vesting, rather than shares of the Company's Class A common stock. During fiscal 2025, we granted Evergreen Fund Unit awards of SPRIM to each of our NEOs, with the value of the grants determined as described above under "—Annual Incentive Compensation," with Evergreen Fund Unit grants representing 20% of each NEO's total equity incentive award. Although similar to RSUs, the Evergreen Fund Units are not subject to FASB ASC Topic 718, and as a result, the value received by each NEO upon vesting of the Evergreen Fund Units will be reported in the year in which vesting occurs.

All of the RSUs and Evergreen Fund Units were granted on March 14, 2025 and vest in four equal annual installments on February 14 of 2026, 2027, 2028 and 2029. The Compensation Committee and the board of directors believe that a four-year vesting period encourages our NEOs to take a longer-term view of our overall performance and stockholder value, while also providing a key retention incentive. The number of RSUs and Evergreen Fund Units received by each NEO are set forth below.

---

| | | | | |
|:---|:---|:---|:---|:---|
| **Name** | **RSUs** | **RSUs** | **Evergreen Fund<br>Units** | **Evergreen Fund<br>Units** |

*Carried Interest and Incentive Fees*. We receive an allocation of performance-based fees, commonly referred to as "carried interest," from limited partners in our investment funds and separately managed accounts for which we act as both investment adviser and general partner or managing member (the "StepStone Funds") and we hold an equity interest. Approximately 50% of carried interest allocation revenue is awarded to certain employees, including our NEOs, as a form of long-term incentive compensation, fostering alignment of interest with our clients and investors, and retaining key investment professionals. Ownership of carried interest by our NEOs may be subject to a range of vesting conditions, including continued employment, and forfeiture upon occurrence of certain specified events post-termination, thus serving as an important employment retention mechanism. Awards granted in April 2020 and thereafter vest over five years; earlier carried interest awards granted to employees vest over eight years. Each carried interest award is subject to accelerated vesting in connection with certain qualifying terminations, as described under "Executive Compensation Tables—Potential Payments Upon Termination or Change in Control—Carried Interest" below.

For StepStone Funds for which we act as the investment adviser but do not have a general partner or other equity interest, incentive fees may be realized pursuant to client investment mandates and are generally calculated as a percentage of the profits, subject to the achievement of minimum return levels or performance benchmarks. Like the carried interest, a portion of the incentive fees we receive are awarded to certain employees, including our NEOs, as a form of long-term incentive compensation.

Each of our NEOs received cash distributions attributable to carried interest awards and each of our NEOs received incentive fee payments in fiscal 2025, all of which are reflected in the "All Other Compensation" column of the Summary Compensation Table below.

##### [**Table of Contents**](#toc)

#### Other Benefits and Perquisites
*Retirement Benefits*. We offer eligible employees, including our NEOs, the opportunity to participate in our tax-qualified 401(k) plan. Employees can contribute an amount that cannot exceed 100% of their eligible compensation up to the Internal Revenue Service's annual limits on either a before-tax or after-tax basis into the 401(k) plan. We make a non-discretionary non-matching contribution to the plan on behalf of all eligible employees equal to 3% of their eligible pay. All company contributions are immediately 100% vested.

*Health and Welfare Benefits*. Our NEOs participate in the same health and welfare benefit programs offered to our broader employee populations. In addition, we provide our NEOs and other senior employees with enhanced life and disability insurance benefits for which the Company pays the premiums.

*Termination Benefits*. As described under "Executive Compensation Tables—Potential Payments Upon Termination or Change in Control" below, StepStone is not party to any employment, severance or change in control arrangements with our NEOs, other than with Mr. Park; however, the outstanding equity awards held by our NEOs and each NEO's carried interest awards are eligible for accelerated vesting in connection with certain termination or change in control events. Historically, we have not viewed severance arrangements for executive officers as necessary due to existing carried interest and the level of other equity held by our executive officers. In May 2025, we entered into a change in control severance agreement with Mr. Park, as described under "Executive Compensation Tables—Potential Payments Upon Termination or Change in Control" below in consideration of market practices and the Company's transition to non-controlled company status in September 2025.

*Perquisites and Other Compensation*. We believe that our executive compensation program provides appropriate compensatory levels without the need for excessive perquisites and benefits. As a result, none of our NEOs received any perquisites in excess of $10,000 during fiscal 2025. We do, however, provide certain limited tax reimbursements for unitholders of the Partnership who provide services to the Partnership, including certain of our NEOs, who own less than one percent of the outstanding units of the Partnership. Such individuals are eligible to receive a self-employment tax make-whole payment in the amount of self-employment tax payable by the individual that would not have been payable by the individual if the individual had the status of an employee of the Partnership for tax purposes.

#### Other Compensation Matters

#### Clawback Policy
We maintain a Clawback Policy which is intended to comply with the requirements of Listing Rule 5608 adopted by the Nasdaq Stock Market to implement Rule 10D-1 under the Exchange Act. In the event StepStone is required to prepare an accounting restatement of its financial statements due to material non-compliance with any financial reporting requirement under the federal securities laws, StepStone will recover, on a reasonably prompt basis, the excess incentive-based compensation received by any covered executive, including the NEOs, during the prior three fiscal years that exceeds the amount that the executive otherwise would have received had the incentive-based compensation been determined based on the restated financial statements.

Practices on Timing of Equity Awards

In granting equity awards to the NEOs, the board of directors has historically used a consistent grant date of February 14 for annual RSU grants, which is expected to be during a scheduled open trading window (as defined under the Company's insider trading policy). Beginning in fiscal 2025, however, the Compensation Committee (and, for Mr. Hart, the board of directors) adjusted the timing of the grant of equity awards to align more closely with StepStone's fiscal year (rather than on a calendar year basis) and granted such awards on March 14, 2025, which was also during a scheduled open trading window. We anticipate that future equity awards will have a grant date in March, but we may change our equity grant timing practices in the future. During fiscal 2025, the Compensation Committee did not take into account any material nonpublic information when determining the timing and terms of equity incentive awards, and we did not time the disclosure of material nonpublic information for the purpose of affecting the value of executive compensation. During fiscal 2025, we did not grant stock options to the NEOs.

Tax and Accounting Implications of Executive Compensation Decisions

In making compensation decisions, the Compensation Committee and the board of directors consider the tax treatment and accounting implications; however, these are not the primary basis upon which our compensation decisions are made and are only secondary considerations to ensuring that our compensation decisions further our overall executive compensation philosophy. As a result, the compensation received by our NEOs may not be fully tax deductible or may have adverse accounting consequences.

Prohibition on Hedging and Pledging

As described under "Board of Directors and Corporate Governance—Prohibitions and Restrictions on Hedging and Pledging Transactions" above, 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 StepStone securities and from pledging StepStone securities as collateral for a loan.

Beginning with RSUs granted to our NEOs in calendar year 2025, each NEO was eligible to elect to defer settlement of such RSUs until a payment event elected by the NEO as either a single lump sum or two to 10 annual installments. An NEO who elects to defer their RSUs will receive shares of Class A common stock on the NEO's elected payment event or earlier death. Only Mr. Fernandez has elected to defer all of his 2025 RSUs to be settled in a single lump sum upon the earlier of June 1, 2030 or his separation from service.

#### Potential Payments Upon Termination or Change in Control

#### Change in Control Severance Agreement
Other than for Mr. Park, we do not have any employment, severance or change in control arrangements with our NEOs. On May 20, 2025, we entered into a Change in Control Severance Agreement with Mr. Park, pursuant to which Mr. Park is eligible to receive the following severance benefits in the event his employment is terminated without Cause or he resigns for Good Reason after we experience a Change in Control: (i) a lump sum cash severance payment equal to two times the sum of (A) Mr. Park's base salary and (B) his annual bonus earned for the preceding fiscal year (including any portion paid in cash and any portion granted as equity awards), (ii) 24 months of company-paid group health plan continuation, and (iii) accelerated vesting of all unvested equity or equity-based awards, carried interest awards and awards under any incentive fee plan (with any performance-based vesting conditions determined in accordance with the applicable plan or award agreement). The severance benefits are subject to Mr. Park's execution and non-revocation of a release of claims. For purposes of the Change in Control Severance Agreement, "Cause," "Good Reason," and "Change in Control" have the same meanings as described below for the RSUs.

#### Carried Interest
Any carried interest awards made to our NEOs vest in full upon a termination due to death or permanent disability. In the event of a termination of employment due to Retirement, all carried interest awards will continue to vest as if the NEO continued to remain employed, subject to the NEO's compliance with certain non-competition and non-solicitation conditions. In the event of an NEO's termination for Cause, 50% of such NEO's carried interest he or she would have retained upon their termination is deemed forfeited.

For purposes of the carried interest awards:

• "Cause" means the commission of any of the following by the NEO and the subsequent failure to cure such breach (if curable) within 30 days after notice from StepStone: (i) conviction of, or plea of guilty or nolo contendere to, any criminal act involving moral turpitude; (ii) material act of dishonesty or fraud or misrepresentation which would reasonably be expected to adversely and materially affect the assets, business or prospects of the StepStone and its affiliates; or (iii) any other similar misconduct that would entitle the StepStone clients of any investment product to remove StepStone as the general partner or manager or cause an early termination of the investment product or its investment period.

• "Retirement" occurs upon a termination of employment other than for Cause on or after attaining age 50 with 15 years of service.

#### Restricted Stock Units and Evergreen Fund Units
Pursuant to the terms of the award agreements for the RSUs and Evergreen Fund Units granted to our NEOs, in the event of a termination of employment due to death or disability, all outstanding RSUs and Evergreen Fund Units will vest in full. In the event of a termination of employment due to Retirement (as defined below), all outstanding

------

##### [**Table of Contents**](#toc)
RSUs and Evergreen Fund Units will continue to vest as though the NEO had remained employed. In addition, in the event of termination of the NEO's employment without Cause (as defined below) or a resignation for Good Reason (as defined below), in each case, upon or within the 13-month period following a Change in Control (as defined below), all unvested RSUs and Evergreen Fund Units will vest in full.

For purposes of the RSU and Evergreen Fund Units award agreements:

• "Cause" means the occurrence of any of the following: (i) the NEO's failure substantially to perform his or her duties and responsibilities to us or our affiliate or violation of any of our policies; (ii) the NEO's commission of any act of fraud, embezzlement, dishonesty or any other misconduct that has caused or is reasonably expected to result in injury to us or our affiliates; (iii) unauthorized use or disclosure by the NEO of any of our proprietary information or trade secrets; or (iv) the NEO's breach of any of his or her obligations under any written agreement or covenant with us or any affiliate.

• "Change in Control" means the occurrence, in a single or series of related transactions of any of the following: (i) any person becomes the owner of 50% or more of the combined voting power of us other than by virtue of a merger, consolidation or similar transaction, (ii) consummation of a merger, consolidation or similar transaction where after such transaction our stockholders do not own 50% or more of the combined voting power of the surviving or parent entity in substantially the same proportions as prior to such transaction, (iii) consummation of sale, lease, license or other disposition of all or substantially all of our assets, or (iv) with respect to the RSUs only, members of the incumbent board of directors ceasing to constitute at least a majority of our board of directors.

• "Good Reason" means the occurrence of any of the following, without the NEO's consent: (i) we reduce the NEO's annual base salary, unless such reduction is pursuant to a general reduction in annual base salaries applicable to all similarly situated employees, (ii) the NEO experiences a significant diminution of position, duties, responsibilities or status or (iii) NEO is required to relocate to a location that exceeds a 50 mile radius from the NEO's primary workplace prior to the Change in Control.

• "Retirement" occurs upon a termination of employment other than for Cause on or after attaining age 50 with 15 years of service.

#### Quantification of Potential Payments
The table below sets forth the aggregate amounts that would have been payable to each NEO with respect to the RSUs and Evergreen Fund Units, as described above, assuming the applicable termination event or change in control occurred on March 31, 2025. The table below does not take into account the Change in Control Severance Agreement with Mr. Park because such agreement was not yet in effect on March 31, 2025. Carried interest is paid based on the price at which the StepStone Funds can 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 retirement, death or disability on March 31, 2025. As of March 31, 2025, only Mr. Fernandez was retirement-eligible for purposes of the carried interest and outstanding RSUs and Evergreen Fund Units.

(1) Amounts in this column represent the value, as of March 31, 2025, of RSUs and Evergreen Fund Units that would continue to vest and settle following the NEO's retirement.

(2) Amounts in this row reflect RSUs that would become vested upon occurrence of the applicable event based on the closing trading price of $52.23 per share as of March 31, 2025, for our Class A common stock listed on the Nasdaq Global Select Market.

(3) Amounts in this row reflect Evergreen Fund Units that would become vested upon occurrence of the applicable event based on the closing price per share of SPRIM of $55.53 as of March 31, 2025.

#### CEO PAY RATIO
The fiscal 2025 total compensation of the median compensated employee as of March 31, 2025, other than Mr. Hart, our Chief Executive Officer, was $163,738; Mr. Hart's fiscal 2025 total compensation was $4,705,412; and the ratio of these amounts was 1-to-29.

The pay ratio reported above is a reasonable estimate calculated in a manner consistent with SEC rules based on our payroll and employment records and the methodology described below. For these purposes, we identified the "median compensated employee" using each employee's fiscal 2025 base salary, cash bonus earned for fiscal 2025 and the grant date fair value of RSUs granted in March 2025, which we annualized for any employee who did not work for the entire year unless designated as a temporary, seasonal or other non-permanent employee on our payroll records (including interns). We identified our employee population as of March 31, 2025 based on our payroll records or based on our treatment of employees for U.S. tax or local tax reporting purposes. We did not exclude any non-U.S. employees.

The SEC's rules for identifying the median compensated employee and calculating the pay ratio based on that employee's annual total compensation allow companies to adopt a variety of methodologies, to apply certain exclusions, and to make reasonable estimates and assumptions that reflect their employee populations and compensation practices. As a result, the pay ratio reported by other companies may not be comparable to the pay ratio reported above, as other companies have different employee populations and compensation practices and may utilize different methodologies, exclusions, estimates and assumptions in calculating their own pay ratios.

(5) Total Shareholder Return (TSR) is calculated by dividing (a) the sum of (i) the cumulative amount of dividends for the measurement period, assuming dividend reinvestment, and (ii) the difference between the Company's share price at the end of each fiscal year shown and the beginning of the measurement period, and the beginning of the measurement period by (b) the Company's share price at the beginning of the measurement period. The beginning of the measurement period for each year in the table is September 16, 2020, the date of the Company's initial public offering.

(6) The peer group used for this purpose is the following published industry index: Dow Jones US Asset Managers Index.

(7) The dollar amounts reported represent the amount of net income reflected in the Company's audited financial statements for the applicable year.

(8) The dollar amounts reported represent the amount of FRE for the applicable year. FRE is a non-GAAP performance measure and is comprised of 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 connection with the arrangements we entered into with the StepStone Private Wealth management team in November 2022, (c) amortization of intangibles, (d) charges associated with acquisitions and transactions, and (e) certain other items that we believe are not indicative of our core operating performance. FRE is presented before income taxes.

Financial Performance Measures

As described further under "Compensation Discussion and Analysis," the Company's executive compensation program reflects our performance-based compensation culture. Although a large portion of our executive compensation program relies heavily on equity ownership and carried interest awards to create a direct link between the compensation realized by our NEOs and the interests of our shareholders and our clients, our annual bonus program utilizes a number of financial and non-financial performance measures to link executive compensation actually paid for fiscal 2025 to the Company's performance:

• FRE ;

• FRE margin ;

• FEAUM ;

• adjusted net income per share ;

• client relationship management ; and

• t eam and culture management .

The Audit Committee adopted a policy for pre-approving all audit and permitted non-audit services provided by Ernst & Young LLP. The Audit Committee annually pre-approves a list of specific services and categories of services, subject to a specified cost level. Part of this approval process includes making a determination as to whether permitted non-audit services are consistent with the SEC's rules on auditor independence. The Audit Committee has delegated authority to the chair of the Audit Committee to pre-approve audit and non-audit services in amounts up to $500,000 (1) per engagement, (2) per additional category of services, or (3) to the extent otherwise required under the policy, for services exceeding the pre-approved budgeted fee levels for the specified service. All of the services and fees identified in the table above were approved in accordance with SEC and Public Company Accounting Oversight Board requirements pursuant to the pre-approval policy described in this paragraph.

#### AUDIT COMMITTEE REPORT
The Audit Committee has reviewed and discussed the Company's audited financial statements with management and Ernst & Young LLP, and has discussed with Ernst & Young LLP the matters required to be discussed by applicable requirements of the Public Company Accounting Oversight board (the "PCAOB") and the Securities and Exchange Commission ("SEC"). Additionally, the Audit Committee has received the written disclosures and the letter from Ernst & Young LLP, as required by the applicable requirements of the PCAOB regarding Ernst & Young LLP's communications with the Audit Committee concerning independence, and has discussed with Ernst & Young LLP its independence. Based upon such review and discussion, the Audit Committee recommended to the Board of Directors that the audited financial statements be included in the Company's Annual Report on Form 10-K for the fiscal year ended March 31, 2025 for filing with the SEC.

Audit Committee of the Board of Directors,

#### PROPOSAL 2—RATIFICATION OF APPOINTMENT OF INDEPENDENT REGISTERED PUBLIC

#### ACCOUNTING FIRM
The Audit Committee is directly responsible for the appointment, compensation, retention and oversight of our independent registered public accounting firm. In accordance with its charter, the Audit Committee evaluates the independent registered public accounting firm's qualifications, performance and independence at least annually.

Our Audit Committee has selected Ernst & Young LLP as the Company's independent registered public accounting firm for the fiscal year ending March 31, 2026. Ernst & Young LLP has served as the Company's independent registered public accounting firm since 2009. The members of the Audit Committee and our board of directors believe that the continued retention of Ernst & Young LLP as StepStone's independent registered public accounting firm is in the best interests of StepStone and its stockholders. Our board of directors and Audit Committee value the opinions of our stockholders and consider the selection of such firm to be an important matter of stockholder concern. The selection of Ernst & Young LLP is accordingly being submitted for ratification of stockholders as a matter of good corporate practice. If the stockholders fail to ratify this selection, our board of directors and Audit Committee will consider the outcome of the vote in determining whether to retain this firm for the fiscal year ending March 31, 2026. Even if the selection is ratified, our Audit Committee in its discretion may direct the appointment of different independent auditors at any time during the year if it determines that such a change would be in the best interests of our Company and stockholders.

The ratification of the appointment of Ernst & Young LLP as our independent registered public accounting firm for our fiscal year ending March 31, 2026 requires the affirmative vote of at least a majority of the voting power of the stock present in person or represented by proxy and entitled to vote on the subject matter. Stockholders may vote "For," "Against," or "Abstain" with respect to this Proposal 2. Abstentions will have the same effect as a vote "Against" on the outcome of Proposal 2. Because we expect broker discretionary voting to be permitted with respect to Proposal 2, we expect there will be no broker non-votes with respect to this Proposal.

One or more representatives of Ernst & Young LLP are expected to be present at the Annual Meeting online and will have an opportunity to make a statement if they wish and be available to respond to appropriate questions.

#### PROPOSAL 3—NON-BINDING AND ADVISORY VOTE TO APPROVE NAMED EXECUTIVE OFFICER COMPENSATION
In accordance with the Dodd-Frank Act and Section 14A of the Exchange Act, we are asking our stockholders to vote, on a non-binding and advisory basis, to approve the compensation of our NEOs for the fiscal year ended March 31, 2025, as disclosed pursuant to the SEC's compensation disclosure rules. This proposal is commonly referred to as a "Say-on-Pay" vote.

As described in detail under the "Compensation Discussion and Analysis," our executive compensation program is rooted in our performance-based compensation culture. We rely heavily on equity ownership and carried interest awards, creating direct links between the compensation realized by our NEOs and the interests of our shareholders and our clients. The components of our executive compensation program are designed to attract, retain, reward and motivate talented executives while offering an effective mix of fixed and variable compensation that balances short-term and long-term compensation considerations that are closely tied to the growth of StepStone and enhanced shareholder value.

Please read the "Compensation Discussion and Analysis" beginning on page 14 and the "Executive Compensation Tables" beginning on page 20 for more information about the compensation of our NEOs during fiscal 2025.

We are asking stockholders to vote "For" the following resolutions:

"RESOLVED, that the stockholders approve, on a non-binding, advisory basis, the compensation paid to the Company's NEOs for the fiscal year ended March 31, 2025, as disclosed pursuant to Item 402 of Regulation S-K, including the Compensation Discussion and Analysis, compensation tables, and narrative discussion disclosed in this Proxy Statement."

Approval, on a non-binding and advisory basis, of the compensation of our NEOs requires the affirmative vote of at least a majority of the voting power of the stock present in person or represented by proxy and entitled to vote on the subject matter. Stockholders may vote "For," "Against," or "Abstain" with respect to this Proposal 3. Abstentions will have the same effect as a vote "Against" on the outcome of Proposal 3, and broker non-votes, if any, will have no effect on this Proposal.

This Say-on-Pay vote is not binding on our board of directors. However, our board of directors and the Compensation Committee will review and consider the results of this Say-on-Pay vote when making future compensation decisions for our NEOs. Our current policy is to hold Say-on-Pay votes on an annual bonus, and thus, we expect that we will conduct our next Say-on-Pay vote at our 2026 annual meeting of stockholders.

#### PROPOSAL 4—AMENDMENT TO THE CERTIFICATE OF INCORPORATION TO LIMIT THE LIABILITY OF CERTAIN OFFICERS AS PERMITTED BY DELAWARE LAW
Our board has unanimously approved and declared advisable, and resolved to recommend to the Company's stockholders that they approve and adopt amendments to our amended and restated certificate of incorporation (the "certificate of incorporation") to amend Article XI thereof to provide for the elimination of monetary liability of certain officers of the company in certain limited circumstances (the "Exculpation Amendment"). The current Article XI already provides exculpation protections to our directors, and that will remain unchanged as a result of the Exculpation Amendment. The following description is a summary only and is qualified in its entirety by reference to <u>Appendix A</u> to this proxy statement, which sets forth the Exculpation Amendment and marks those changes specifically, as described in <u>Appendix A</u>.

#### Background on and Summary of the Exculpation Amendment
Under Section 102(b)(7) of the General Corporation Law of the State of Delaware (the "DGCL"), Article XI of the certificate of incorporation already eliminates the monetary liability of directors in accordance with the DGCL. Effective August 1, 2022, Section 102(b)(7) of the DGCL was amended to permit companies to include in their certificates of incorporation limitations of monetary liability for certain officers. Consistent with Section 102(b)(7) of the DGCL, as currently in effect, the Exculpation Amendment would only permit limiting the liability of the following officers: (i) the president, chief executive officer, chief operating officer, chief financial officer, chief legal officer, controller, treasurer or chief accounting officer; (ii) individuals who are or were identified in the corporation's public filings as its most highly compensated officers; and (iii) individuals who, by written agreement with the corporation, consented to be identified as officers for purposes of accepting service of process (such officers from time to time specified in Section 102(b)(7) of the DGCL, the "covered officers").

The Exculpation Amendment would exculpate the covered officers only in connection with direct claims for breaches of the fiduciary duty of care brought by stockholders, including class actions. Consistent with Section 102(b)(7) of the DGCL as currently in effect, the Exculpation Amendment would not eliminate or limit liability with respect to any:

• claims brought by the Company itself;

• claims brought by stockholders in the name of the Company, such as derivative claims;

• claims involving breach of the duty of loyalty to the Company or its stockholders;

• claims involving acts or omissions not made in good faith or which involve intentional misconduct or knowing violations of the law; or

• claims involving transactions from which the covered officer derived an improper personal benefit.

For the avoidance of doubt, the current exculpation protections available to the Company's directors under Article XI of the certificate of incorporation would remain unchanged as a result of the Exculpation Amendment. Notwithstanding the foregoing, consistent with the language for exculpation of directors currently included in the certificate of incorporation, the Exculpation Amendment also provides that if, at any time following the effectiveness of the Exculpation Amendment, the DGCL is amended to authorize any further elimination or limitation of the personal liability of a corporation's covered officers (including any change in the roles deemed to be covered officers for purposes of Section 102(b)(7) of the DGCL), then such liability shall be automatically eliminated or limited to the fullest extent permitted by the DGCL, as so amended, with respect to the Company's covered officers (including with respect to any role newly deemed to be a covered officer for purposes of Section 102(b)(7) of the DGCL).

------

##### [**Table of Contents**](#toc)

#### Reasons for the Exculpation Amendment
Our board believes that it is important to extend exculpation protection to our covered officers to the fullest extent permitted by DGCL for a number of reasons, including to maintain the Company's ability to attract, motivate and retain well qualified and highly experienced officers. In the absence of such protection, such individuals could be deterred from serving as officers in light of their potential exposure to personal liability and the risk of incurring substantial expenses in defending lawsuits, regardless of merit. Our officers are often required to make decisions on critical matters by virtue of the nature of their roles, frequently in time-sensitive circumstances, which can create a substantial risk of lawsuits that seek to impose liability with the benefit of hindsight. By helping to align the protections available to the Company's covered officers with those currently available to its directors, we believe the Exculpation Amendment would empower officers to exercise their business judgment more confidently in furtherance of stockholder interests, while removing potential distractions that the risk of personal monetary liability may pose.

Because the Exculpation Amendment would apply only to a narrow class of covered officers, and would still permit, among others, derivative stockholder or Company claims against covered officers, claims involving breaches of the duty of loyalty, acts taken in bad faith, intentional misconduct, knowing violations of the law and/or the receipt of improper personal benefits, the board believes that the Exculpation Amendment will serve to maintain management's accountability to stockholders, while improving our ability to attract and retain qualified officers In light of the foregoing, our board has unanimously approved the Exculpation Amendment, declared it advisable and in the best interests of the Company and our stockholders, and recommended that stockholders adopt the Exculpation Amendment.

#### Additional Information
If our stockholders approve the Exculpation Amendment, it will become effective upon the filing of a Certificate of Amendment to our certificate of incorporation setting forth the Exculpation Amendment with the Delaware Secretary of State, which we anticipate doing as soon as practicable following stockholder approval of the Exculpation Amendment. The board reserves the right to elect to abandon the Exculpation Amendment, without further action by the stockholders, at any time prior to the effectiveness of the Certificate of Amendment setting forth the Exculpation Amendment. If the board were to exercise such discretion, we will publicly disclose that fact, and the Company's covered officers will not become subject to the foregoing exculpation protections. If our stockholders do not approve the Exculpation Amendment, Article XI will remain unchanged, our covered officers will not become subject to the foregoing exculpation protections, and a Certificate of Amendment setting forth the Exculpation Amendment will not be filed with the Delaware Secretary of State.

#### Vote Required; Recommendation of the Board of Directors
The Exculpation Amendment requires the affirmative vote of the holders of at least a majority of the voting power of the outstanding stock entitled to vote on the subject matter, voting as a single class. Abstentions and broker non-votes, if any, will have the same effect as votes against the Exculpation Amendment.

#### PROPOSAL 5—AMENDMENTS TO THE CERTIFICATE OF INCORPORATION TO REMOVE OBSOLETE PROVISIONS AND TO MAKE CERTAIN OTHER CLARIFYING, TECHNICAL AND CONFORMING CHANGES
As described in section "Board of Directors and Corporate Governance—Status as a Controlled Company" of this proxy statement, a Sunset will occur on September 18, 2025, at which point (i) the holders of each share of our Class B common stock will no longer be entitled to five votes per share, but will instead be entitled one vote per share (which is the same as is currently the case for Class A common stock), and (ii) the Stockholders Agreement will terminate. Therefore, we will no longer qualify as a "controlled company" within the meaning of Nasdaq's corporate governance rules and will transition to a non-controlled company status, subject to applicable phase-in periods. At such time, the provisions of our certificate of incorporation related to the Sunset will no longer be operative. In addition, Section 4.8 of Article IV in our certificate of incorporation includes provisions related to certain Class B2 Unit vestings and certain anti-dilution events, all of which have been completed and, therefore, those provisions are also no longer operative. Finally, starting with this Annual Meeting, all of our directors are standing for annual elections and our board is no longer classified, so the provisions related to the classification of the board are no longer operative. In order to simplify and streamline our certificate of incorporation, our board of directors has unanimously approved and declared advisable, and resolved to recommend to the Company's stockholders, that they approve and adopt amendments to our certificate of incorporation that remove these provisions once they are no longer operative and make certain other clarifying, technical and conforming changes to the certificate of incorporation (collectively, the "Clean-Up Amendments").

The following description is a summary only and is qualified in its entirety by reference to <u>Appendix B</u> to this proxy statement, which sets forth the Clean-Up Amendments and marks those changes specifically, as described in <u>Appendix B</u>.

#### Summary of and Reasons for the Clean-Up Amendments
This Proposal 5 requests that stockholders approve the following Clean-Up Amendments:

• <u>Eliminating all references to the high vote stock, Sunset and its effect on the voting rights of Class</u> <u>B Common Stock</u>: Section 4.2 of Article IV currently details the terms and rights of our Class B common stock. As set forth in our certificate of incorporation, the Class B common stock is identical to the Class A common stock, except that the Class B common stock (i) is not entitled to receive dividends and (ii) is entitled to five votes for each share of Class B common stock held until a Sunset occurs, at which time Class B common stock becomes automatically entitled to one vote for each share of Class B common stock held. Article IV, Section 4.2 also includes a definition of when the Sunset shall occur. The Sunset will occur on September 18, 2025, after which the references to the Class B common stock having five votes per share until the Sunset will no longer be operative. The Clean-Up Amendments amend Section 4.2, as reflected in <u>Appendix B,</u> to remove the references to the Class B common stock having five votes per share and the Sunset.

• <u>Eliminating all references to Class</u> <u>B2 Units and anti-dilution provisions applicable to Class</u> <u>B2 units</u>: Sections 4.8(a) and (b) of Article IV currently address the rights under the Partnership Agreement of StepStone Group LP related to Class B2 Units and certain anti-dilution events (each as defined or set forth in the Partnership Agreement of StepStone Group LP). All Class B2 Units have now vested and have become Class B units, and all Class B units issuable under the anti-dilution provisions were issued upon the vesting of the Class B2 units. As a result, these provisions are no longer operative. The Clean-Up Amendments amend Section 4.8(a) and (b), as reflected in Appendix B to remove these inoperative provisions.

• <u>Amendments related to Section</u> <u>242 of the Delaware General Corporation Law (the "DGCL")</u>: Section 4.4 of Article IV will be amended to remove the specific reference to the voting standard required under Section 242(b)(2) of the DGCL to approve an amendment to the certificate of incorporation that increases or decreases the authorized number of shares of the Company's preferred

------

##### [**Table of Contents**](#toc)
stock or common stock (collectively, "authorized share capital"). The amendment would clarify that this provision is intended only to opt out of the class vote that would otherwise be required under Section 242(b)(2) to increase or decrease the authorized number of shares of the class, but not to opt out of the voting standard for increases or decreases to the authorized share capital that are approved under Section 242(d) of the DGCL ("Section 242(d)"). Section 242(d) was recently added to the DGCL to, among other things, permit a corporation to increase or decrease the authorized number of shares of a class of stock, or to reclassify by combining the issued shares of a class of stock into a lesser number of issued shares (referred to as a "reverse stock split") if, among other things, (a) the class of stock is listed on a national securities exchange and will meet the listing requirements of that exchange relating to the minimum number of holders immediately after the amendment becomes effective, and (b) the votes cast "for" the amendment exceed the votes cast "against" the amendment at a meeting at which a quorum of the stockholders is present in person or by proxy. These changes are clarifying changes only, to avoid potential interpretative questions relating to the application of the voting standard currently referenced in Section 4.4 to an amendment subject to Section 242(d). <br>

• <u>Declassification-Related Amendments</u>: Because our board is no longer classified, the Clean-Up Amendments remove no longer applicable references to the phase-in of the declassification of our board of directors as well as related vacancy and removal provisions contained in Sections 5.2(a), (b) and (c) of Article V.

• <u>Other Conforming Changes</u>: Because there is a reference to "Sunset Holders" in Article VIII, Section (c)(viii), which term is currently defined in Section 4.2 of Article IV and is proposed to be removed from the certificate of incorporation in connection with these Clean-Up Amendments, the Clean-Up Amendments also propose to replace the reference to the "Sunset Holders" in the definition of "Principal Holders" in Article VIII with the actual definition that was previously included in Section 4.2 (except Johnny Randel has been removed from the definition since he has retired and is no longer with StepStone). This is purely a conforming and otherwise non-substantive change.

In its review of the Clean-Up Amendments, the board of directors considered the events discussed above related to the Sunset and other inoperative provisions and the need and desire to avoid potential confusion relating to our certificate of incorporation, including provisions that are no longer applicable on a go-forward basis and other provisions that could be misconstrued in light of recent amendments to the DGCL. In addition, the board of directors considered that the Clean-Up Amendments eliminating the inoperative provisions and making other clarifying, technical and conforming changes are clarifying only and have no effect on the existing rights of stockholders. While the Sunset has not yet occurred, the board determined it in the best interests of stockholders to have the Clean-Up Amendments go into effect immediately after the Sunset occurs and thus is seeking approval in advance of the Sunset, so the Clean-Up Amendments could be effective shortly after the Sunset without having to wait until the next annual meeting or incurring the expense of a special meeting of stockholders. Based on these considerations, our board of directors adopted resolutions setting forth the Clean-Up Amendments, declared the Clean-Up Amendments advisable and in the best interests of the Company and our stockholders, and unanimously resolved to submit the Clean-Up Amendments to our stockholders for approval.

#### Additional Information
If our stockholders approve the Clean-Up Amendments, they will become effective upon the filing of a Certificate of Amendment to our certificate of incorporation setting forth the Clean-Up Amendments with the Delaware Secretary of State. As discussed above, because the Sunset will not occur until September 18, 2025, the Clean-Up Amendments cannot become effective before that date. We currently anticipate filing the Certificate of Amendment with respect to the Clean-Up Amendments as soon as practicable following the Sunset (which would be on or shortly after September 18, 2025). The board reserves the right to elect to abandon the Clean-Up Amendments, without further action by the stockholders, at any time prior to the effectiveness of the Certificate of Amendment setting forth the Clean-Up Amendments. If the board were to exercise such discretion, we will publicly disclose that fact, and the certificate of incorporation will not be amended to reflect the Clean-Up Amendments.

------

##### [**Table of Contents**](#toc)
If our stockholders do not approve the Clean-Up Amendments, the references to the Sunset, phased-in board declassification, non-conforming DGCL provisions and other inoperative provisions summarized above will remain in our certificate of incorporation, the Clean-Up Amendments described above will not be made, and the Certificate of Amendment setting forth the Clean-Up Amendments will not be filed with the Delaware Secretary of State.

#### Vote Required; Recommendation of the Board of Directors
Approval of the Clean-Up Amendments requires the affirmative vote of the holders of (i) at least a majority of the voting power of the outstanding stock entitled to vote on the subject matter, voting as a single class and (ii) at least a majority of the outstanding shares of Class B common stock, voting as a separate class. Abstentions and broker non-votes, if any, will have the same effect as votes against the Clean-Up Amendments.

#### CERTAIN RELATIONSHIPS AND RELATED PERSON TRANSACTIONS

#### Procedures for Review, Approval, and Ratification of Related Person Transactions
Our board of directors has adopted a written policy regarding the review, approval, ratification or disapproval by our Audit Committee of transactions between us or any of our subsidiaries and any related person (defined in the policy to include our executive officers, directors or director nominees, any stockholder beneficially owning in excess of 5% of any class of our stock or securities exchangeable for our stock and any immediate family member of any of the foregoing persons) in which the amount involved since the beginning of our last completed fiscal year will or may be expected to exceed $120,000 and in which one or more of such related persons has a direct or indirect interest. In approving or disapproving any such transaction, our Audit Committee considers the relevant facts and circumstances available and deemed relevant to the Audit Committee. Any member of the Audit Committee who is a related person with respect to a transaction under review will not be permitted to participate in the deliberations or vote on approval, ratification or disapproval of the transaction.

Other than the transactions described below under the "Related Person Transactions," there have been no other "related person transactions" that require disclosure under the SEC rules since the beginning of our last completed fiscal year.

#### Related Person Transactions

#### Transactions with Management, our Directors and Certain Beneficial Owners
One of our directors, Steven Mitchell, is a controlling stockholder and serves on the investment committee of Argonaut Private Capital, LP, which manages several private equity investment funds. In connection with the formation of one of these funds, an affiliate of ARG Private Equity, LLC (formerly Argonaut Private Equity, LLC), directly and indirectly, sold investments represented by capital commitments of $400 million in the aggregate. The purchasers included accounts managed or advised by the Partnership. Since April 1, 2024 (i.e., the beginning of the last completed fiscal year) no additional capital commitments have been made by accounts managed or advised by the Partnership (including related investments by the Partnership), in the funds managed by Argonaut Private Capital, LP. Accounts advised by us (non-discretionary clients) have paid management fees to Argonaut Private Capital, LP aggregating to $804,914 since April 1, 2024. Mr. Mitchell benefitted from these payments in his capacity as controlling stockholder of Argonaut Private Capital, LP.

Additionally, each of Thomas Bradley, David Jeffrey and Mark Maruszewski, are non-executive officer partners of the Partnership who hold more than 5% of the Class B common stock of the Company. James Lim is a non-executive partner of the Partnership who holds more than 5% of the Class A common stock of the Company. Since April 1, 2024, each of Messrs. Bradley, Jeffrey, Maruszewski and Lim received compensation and partnership distributions from the Partnership in excess of $120,000.

In addition, certain persons, including our employees and partners of the Partnership, and directors of the Company, have the opportunity to invest their personal capital in the StepStone Funds on the same terms and conditions as other unaffiliated clients and investors, except that these investments are generally not subject to management fees or carried interest and in some cases feature arrangements that result in a net effective reduced management fee. Investments by any such persons in StepStone Private Markets Fund, StepStone Private Venture and Growth Fund, StepStone Private Infrastructure Fund and Stepstone Private Credit Income Fund, which are all funds for which the Partnership or one of its subsidiaries acts as sub-adviser, are subject to management fees and, as applicable, carried interest. We encourage these persons to invest in the StepStone Funds because we believe that such investing further aligns their interests with those of our fund investors and our firm. The following table sets forth the Company's executive officers, employees and partners who are stockholders beneficially owning in excess of 5% of a class our stock, and non-independent directors (and their

##### [**Table of Contents**](#toc)
respective family members and investment vehicles) that have made commitments to the StepStone Funds between April 1, 2024 and April 30, 2025 and that have received distributions from the StepStone Funds as a result of their invested capital during that period:

#### Transactions in Connection with our Reorganization and Initial Public Offering

#### The Reorganization
The following are summaries of certain provisions of our related party agreements, including agreements entered into in connection with our initial public offering, which summaries are qualified in their entirety by reference to all of the provisions of such agreements. Because these descriptions are only summaries of the applicable agreements, they do not necessarily contain all of the information that you may find useful. We therefore encourage you to review the agreements in their entirety.

#### Tax Receivable Agreements
We entered into Tax Receivables Agreements in connection with our initial public offering in September 2020, the acquisition of Greenspring Associates in September 2021 and the Transaction Agreements dated February 7, 2024 as disclosed in the Form 8-K filed February 8, 2024. Certain members of the Company's senior management are party to the Tax Receivables Agreement entered into in connection with our initial public offering.

The limited partners of the Partnership (not including the Company) may exchange their Class B, Class C or Class D units for shares of the Company's Class A common stock on a one-for-one basis or, at the Company's election, for cash. When a Class B unit is exchanged for a share of the Company's Class A common stock or cash, a corresponding share of our Class B common stock will automatically be redeemed by us at par value and canceled. No shares of common stock are redeemed when a Class C or Class D unit is exchanged for a share of the Company's Class A common stock or cash.

As a result of these purchases and any subsequent exchanges, we are entitled to a proportionate share of the existing tax basis of the assets of the Partnership. In addition, the Partnership and certain of its direct or indirect subsidiaries that are treated as partnerships for U.S. federal income tax purposes will have in effect an election

------

##### [**Table of Contents**](#toc)
under Section 754 of the Code for the taxable year of the initial public offering, any secondary offerings and any exchange, which is expected to result in increases to the tax basis of the tangible and intangible assets of the Partnership which will be allocated to the Company. These increases in tax basis are expected to increase the Company's depreciation and amortization deductions for tax purposes and create other tax benefits and may also decrease gains (or increase losses) on future dispositions of certain assets and therefore may reduce the amount of tax that the Company would otherwise be required to pay.

The Tax Receivable Agreements generally provide for payment by the Company to certain partners of the Partnership (not including the Company) of 85% of the amount of the net cash tax savings, if any, that the Company realizes (or, under certain circumstances, is deemed to realize) as a result of increases in tax basis (and utilization of certain other tax benefits) resulting from (i) the Company's acquisition of such partner's Partnership units in connection with the initial public offering, any secondary offerings and any exchanges from Partnership units into Company Class A common stock and (ii) any payments the Company makes under the Tax Receivable Agreement (including tax benefits related to imputed interest).

The Company will retain the benefit of the remaining 15% of these net cash tax savings. The obligations under the Tax Receivable Agreements are the Company's obligations and not obligations of the Partnership. For purposes of each Tax Receivable Agreement, the benefit deemed realized by the Company will be computed by comparing the Company's U.S. federal, state and local income tax liability to the amount of such U.S. federal, state and local taxes that the Company would have been required to pay had it not been able to utilize any of the benefits subject to such Tax Receivable Agreement. The actual tax benefits realized by the Company may differ from tax benefits calculated under the Tax Receivable Agreements as a result of the use of certain assumptions in the Tax Receivable Agreements, including the use of an assumed weighted-average state and local income tax rate to calculate tax benefits. In addition, the StepStone Limited Partnership Agreement provides that the Partnership may elect to apply an allocation method with respect to certain of the Partnership investment assets that were held at the time of the closing of our initial public offering that is expected to result in the future, solely for tax purposes, in certain items of loss being specially allocated to StepStone and corresponding items of gain being specially allocated to the other partners of the Partnership.

The term of each Tax Receivable Agreement will continue until all tax benefits that are subject to such Tax Receivable Agreement have been utilized or have expired, unless the Company exercises its right to terminate such Tax Receivable Agreement (or such Tax Receivable Agreement is terminated due to a change in control or our breach of a material obligation thereunder), in which case, the Company will be required to make the termination payment specified in such Tax Receivable Agreement, as specified below. We expect that all of the intangible assets, including goodwill, of the Partnership allocable to the Partnership units acquired or deemed acquired by the Company from existing partners of the Partnership at the time of our initial public offering, any secondary offerings and any exchanges from Partnership units into Class A common stock will be amortizable for tax purposes.

Estimating the amount and timing of payments that may be made under a Tax Receivable Agreement is by its nature imprecise, insofar as the calculation of amounts payable depends on a variety of factors and future events. The actual increase in tax basis and utilization of tax attributes, as well as the amount and timing of any payments under the agreement, will vary depending upon a number of factors, some of which may only be applicable to one of the Tax Receivable Agreements, including:

• the timing of purchases or future exchanges—for instance, the increase in any tax deductions will vary depending on the fair market value, which may fluctuate over time, of the depreciable or amortizable assets of the Partnership at the time of each purchase of units from the partners of the Partnership in each future exchange;

• the price of shares of our Class A common stock at the time of the purchase or exchange—the tax basis increase in the assets of the Partnership is directly related to the price of shares of our Class A common stock at the time of the purchase or exchange;

------

##### [**Table of Contents**](#toc)
• the extent to which such purchases or exchanges are taxable—if the purchase of units from the partners of the Partnership in connection with any secondary offerings or any future exchange is not taxable for any reason, increased tax deductions will not be available;

• the amount of the exchanging unitholder's tax basis in its units at the time of the relevant exchange;

• the amount and timing of the utilization of tax attributes;

• the amount, timing and character of the Company's income—we expect that the Tax Receivable Agreements will require the Company to pay 85% of the net cash tax savings as and when deemed realized. If the Company does not have taxable income during a taxable year, the Company generally will not be required (absent a change in control or other circumstances requiring an early termination payment) to make payments under the Tax Receivable Agreements for that taxable year because no benefit will have been realized. However, any tax benefits that do not result in net cash tax savings in a given tax year may generate tax attributes that may be used to generate net cash tax savings in previous or future taxable years. The use of any such tax attributes will generate net cash tax savings that will result in payments under the Tax Receivable Agreements; and

• U.S. federal, state and local tax rates in effect at the time that we realize the relevant tax benefits.

In addition, the depreciation and amortization periods that apply to the increases in tax basis, the timing and amount of any earlier payments that the Company may have made under a Tax Receivable Agreement and the portion of the Company's payments under such Tax Receivable Agreement that constitute imputed interest or give rise to depreciable or amortizable tax basis are also relevant factors.

The Company has the right to terminate each Tax Receivable Agreement, in whole or in part, at any time. Each Tax Receivable Agreement provides that if (i) the Company exercises its right to early termination of the Tax Receivable Agreement in whole (that is, with respect to all benefits due to all beneficiaries under the Tax Receivable Agreement) or in part (that is, with respect to some benefits due to all beneficiaries under the Tax Receivable Agreement), (ii) the Company experiences certain changes in control, (iii) the Tax Receivable Agreement is rejected in certain bankruptcy proceedings, (iv) the Company fails (subject to certain exceptions) to make a payment under the Tax Receivable Agreement within 180 days after the due date or (v) the Company materially breaches its obligations under the Tax Receivable Agreement, the Company will be obligated to make an early termination payment to the beneficiaries under the Tax Receivable Agreement equal to the present value of all payments that would be required to be paid by the Company under the Tax Receivable Agreement. The amount of such payments will be determined on the basis of certain assumptions in each Tax Receivable Agreement, including (i) the assumption that the Company would have enough taxable income to fully utilize the tax benefit resulting from the tax assets which are the subject of such Tax Receivable Agreement; (ii) the assumption that any item of loss deduction or credit generated by a basis adjustment or imputed interest arising in a taxable year preceding the taxable year that includes an early termination will be used by the Company ratably from such taxable year through the earlier of (x) the scheduled expiration of such tax item or (y) 15 years; (iii) in the case of one of the Tax Receivable Agreements, the assumption that certain net operating losses (and similar items) inherited from the counterparties will be used by the Company as contemplated in such agreement; (iv) the assumption that any non-amortizable assets are deemed to be disposed of in a fully taxable transaction on the fifteenth anniversary of the earlier of the basis adjustment and the early termination date; (v) the assumption that U.S. federal, state and local tax rates will be the same as in effect on the early termination date, subject to exceptions; and (vi) the assumption that any units (other than those held by the Company) outstanding on the termination date are deemed to be exchanged for an amount equal to the market value of the corresponding number of shares of Class A common stock on the termination date. The amount of the early termination payment is determined by discounting the present value of all payments that would be required to be paid by the Company under the Tax Receivable Agreement at a rate specified the applicable agreement.

The payments that we are required to make under each Tax Receivable Agreements are expected to be substantial. Based on certain assumptions, including no material changes in the relevant tax law and that the

Company earns sufficient taxable income to realize the full tax benefits that are the subject of the Tax Receivable Agreements, as of March 31, 2025, we expect that future payments under the Tax Receivables Agreements will equal $313.7 million in the aggregate, although estimating the amount of payments that may be made under the Tax Receivable Agreements is by its nature imprecise, insofar as the calculation of amounts payable depends on a variety of factors and future events.

Decisions made in the course of running our business, such as with respect to mergers and other forms of business combinations that constitute changes in control, may influence the timing and amount of payments we make under the Tax Receivable Agreements in a manner that does not correspond to our use of the corresponding tax benefits. In these situations, our obligations under the Tax Receivable Agreements could have a substantial negative effect on our liquidity and could have the effect of delaying, deferring or preventing certain mergers, asset sales, other forms of business combinations or other changes of control.

Payments are generally due under the Tax Receivable Agreements within a specified period of time following the filing of the Company's tax return for the taxable year with respect to which the payment obligation arises, although interest on such payments will begin to accrue at a rate specified in the applicable agreement from the due date (without extensions) of such tax return. Because of our structure, our ability to make payments under the Tax Receivable Agreements is dependent on the ability of the Partnership to make distributions to us. The ability of the Partnership to make such distributions will be subject to, among other things, restrictions in the agreements governing our debt. If we are unable to make payments under the Tax Receivable Agreements for any reason, such payments will be deferred and will accrue interest until paid.

Payments under the Tax Receivable Agreements will be based on the tax reporting positions that we determine. Although we are not aware of any material issue that would cause the Internal Revenue Service ("IRS") to challenge a tax basis increase or the inheritance of tax attributes from the blocker companies, the Company will not, in the event of a successful challenge, be reimbursed for any payments previously made under a Tax Receivable Agreement (although the Company would reduce future amounts otherwise payable to a holder of rights under such Tax Receivable Agreement to the extent such holder has received excess payments). No assurance can be given that the IRS will agree with our tax reporting positions, including the allocation of value among our assets. In addition, the required final and binding determination that a holder of rights under a Tax Receivable Agreement has received excess payments may not be made for a number of years following commencement of any challenge, and the Company will not be permitted to reduce its payments under a Tax Receivable Agreement until there has been a final and binding determination, by which time sufficient subsequent payments under the Tax Receivable Agreement may not be available to offset prior payments for disallowed benefits. As a result, in certain circumstances, payments could be made under a Tax Receivable Agreement significantly in excess of the benefit that the Company actually realizes in respect of the increases in tax basis (and utilization of certain other tax benefits). The Company may not be able to recoup those payments, which could adversely affect the Company's financial condition and liquidity.

No holder of rights under the Tax Receivable Agreements may transfer its rights to another person without the written consent of the Company, except that all such rights may be transferred to another person to the extent that the corresponding Partnership units are transferred in accordance with the StepStone Limited Partnership Agreement.

Certain of our directors, executive officers and beneficial owners of more than 5% of our Class A common stock or Class B common stock received payments pursuant to the Tax Receivable Agreement. Payments that require disclosure under Item 404 of Regulation S-K were as follows: (i) in fiscal 2025, Mr. Brem, directly and through MMAR HNL, LLC, received $2,207,435; Mr. Fernandez, through a family trust, received $532,348; Mr. Hart, through a family trust, received $36,538; Mr. McCabe, directly and through a family trust, received $456,630; Mr. Keck, through a family trust, received $440,818; Mr. Maruszewski received $287,569; Mr. Bradley received $220,293; Mr. Jeffrey received $372,144; ARGO Holdings, LLC received $1,844,787; entities affiliated with T.

#### StepStone Limited Partnership Agreement
The Partnership is governed by a Tenth Amended and Restated Partnership Agreement, dated May 31, 2024 (as amended and restated from time to time, the "StepStone Limited Partnership Agreement"). StepStone Group Holdings LLC, a Delaware limited liability company (the "General Partner") acts as the sole general partner of the Partnership, and the Company owns a 100% membership interest in the General Partner and is its sole managing member.

The Tenth Amended and Restated StepStone Group LP Limited Partnership Agreement (the "Tenth LPA") was entered into on May 31, 2024 and established a new class of partnership units titled Class D units. On May 31, 2024, the Company and the Partnership completed the first annual exchange pursuant to the Transaction Agreements dated February 7, 2024 (the "2024 Exchange"). In the 2024 Exchange, the Company issued 513,394 shares of Class A common stock and the Partnership issued 2,239,185 Class D units and paid approximately $13 million in cash to acquire equity interests of StepStone Group Real Estate LP, a Delaware limited partnership, StepStone Group Real Assets LP, a Delaware limited partnership and StepStone Group Private Debt AG, a private company limited by shares incorporated in the canton of Zurich (together, the "Asset Class Entities").

On May 30, 2025, the Company and the Partnership completed the second annual exchange pursuant to the Transaction Agreements dated February 7, 2024 (the "2025 Exchange"). Inclusive of adjustments under the Transaction Agreements related to the 2024 Exchange, in the 2025 Exchange the Company issued 756,105 shares of Class A common stock and Partnership issued 2,438,403 Class D units and paid approximately $11 million in cash to acquire equity interests of the Asset Class Entities.

In its capacity as the sole managing member of the General Partner, the Company controls all of the Partnership's business and affairs. The Company holds all of the Class A units of the Partnership. Holders of Class A units, Class B units, Class C units and Class D units are generally entitled to one vote per unit with respect to all matters as to which partners are entitled to vote under the StepStone Limited Partnership Agreement. Class A units, Class B units, Class C units and Class D have the same economic rights per unit.

At any time the Company issues a share of Class A common stock for cash, the net proceeds received by the Company will be promptly used to acquire a Class A unit unless used to settle an exchange of a Class B unit for cash. Any time the Company issues a share of Class A common stock upon an exchange of a Class B unit or settles such an exchange for cash, as described below under "—Exchange Agreement," the Company will contribute the exchanged unit to the Partnership and the Partnership will issue to the Company a Class A unit. If the Company issues other classes or series of equity securities, the Partnership will issue to the Company an equal amount of equity securities of the Partnership with designations, preferences and other rights and terms that are substantially the same as the Company's newly issued equity securities. Conversely, if the Company retires any shares of Class A common stock (or equity securities of other classes or series) for cash, the Partnership will, immediately prior to such retirement, redeem an equal number of Class A units (or its equity securities of the corresponding classes or series) held by the Company, upon the same terms and for the same price, as the shares of the Company's Class A common stock (or equity securities of such other classes or series) are retired. In addition, membership units of the Partnership, as well as our common stock, will be subject to equivalent stock splits, dividends, reclassifications and other subdivisions.

------

##### [**Table of Contents**](#toc)
The Company will have the right to determine when distributions will be made to holders of units and the amount of any such distributions, other than with respect to tax distributions as described below. If a distribution is authorized, except as described below, such distribution will be made to the holders of Class A units, Class B units, Class C units and Class D on a pro rata basis in accordance with the number of units held by such holder.

The holders of units, including the Company, will incur U.S. federal, state and local income taxes on their proportionate share of any taxable income of the Partnership. Net profits and net losses of the Partnership will generally be allocated to holders of units (including the Company) on a pro rata basis in accordance with the number of units held by such holder; however, under applicable tax rules, the Partnership will be required to allocate net taxable income disproportionately to its partners in certain circumstances. The StepStone Limited Partnership Agreement provides for quarterly cash distributions, which we refer to as "tax distributions," to the holders of the units generally equal to the taxable income allocated to each holder of units (with certain adjustments) multiplied by an assumed tax rate. Generally, these tax distributions will be computed based on our estimate of the net taxable income of the Partnership allocable per unit (based on the partner which is allocated the largest amount of taxable income on a per unit basis) multiplied by an assumed tax rate equal to the highest combined U.S. federal and applicable state and local tax rate applicable to any natural person residing in, or corporation doing business in, New York City or San Francisco, California that is taxable on that income (taking into account the deductibility of state and local taxes for U.S. federal income tax purposes and certain other assumptions). The StepStone Limited Partnership Agreement generally requires tax distributions to be pro rata based on the ownership of Partnership units, however, if the amount of tax distributions to be made exceeds the amount of funds available for distribution, the Company shall receive a tax distribution calculated using the corporate tax rate, before the other partners receive any distribution and the balance, if any, of funds available for distribution shall be distributed first to the other partners pro rata in accordance with their assumed tax liabilities (also using the corporate tax rate), and then to all partners (including the Company) pro rata until each partner receives the full amount of its tax distribution using the individual tax rate. The Partnership will also make non-pro rata payments to the Company to reimburse it for corporate and other overhead expenses (which payments from the Partnership will not be treated as distributions under the StepStone Limited Partnership Agreement). Notwithstanding the foregoing, no distribution will be made pursuant to the StepStone Limited Partnership Agreement to any unit holder if such distribution would violate applicable law or result in the Partnership or any of its subsidiaries being in default under any material agreement governing indebtedness.

The StepStone Limited Partnership Agreement provides that the Partnership may elect to apply an allocation method with respect to certain Partnership investment assets that were held at the time of the closing of the secondary offerings that is expected to result in the future, solely for tax purposes, in certain items of loss being specially allocated to us and corresponding items of gain being specially allocated to the other partners of the Partnership.

The StepStone Limited Partnership Agreement provides that it may generally be amended, supplemented, waived or modified by the Company in its sole discretion without the approval of any other holder of units, except that no amendment can adversely affect the rights of a holder of any class of units without the consent of holders of a majority of the units of such class.

#### Stockholders Agreement
Certain of the Class B stockholders, Class C unitholders and Class D unitholders are party to a Stockholders Agreement with respect to all shares of voting stock held by them. Pursuant to the Stockholders Agreement, these stockholders have agreed to vote all their shares of voting stock, including Class A common stock and Class B common stock, together and in accordance with the instructions of the Class B Committee (as described below) on any matter submitted to our common stockholders for a vote.

The Stockholders Agreement provides for a "Class B Committee" selected from time to time by the parties to that agreement. As of the date of this proxy statement, the members of the Class B Committee currently are Monte Brem, Scott Hart, Jason Ment, Jose Fernandez, Michael McCabe and Thomas Keck.

------

##### [**Table of Contents**](#toc)
Under the Stockholders Agreement, the Class B Committee is entitled to designate director nominees for election at our annual meetings of stockholders. The Company and the stockholders who are parties to the Stockholders Agreement shall take all necessary action (subject to fiduciary duties of directors with respect to any action by the board of directors) to cause the persons so designated by the Class B Committee to be the full slate of nominees recommended by our board of directors (or any committee or subcommittee thereof) for election as directors at each annual or special meeting of stockholders at which directors are to be elected. The parties to the Stockholders Agreement have agreed to vote their voting stock, including their Class A common stock and Class B common stock, as directed by the Class B Committee. As a result of these arrangements, the Class B Committee will control the outcome of any such matters that are submitted to our stockholders for five years from the initial public offering.

The Stockholders Agreement will expire on September 18, 2025. After that date, the Class B Committee will dissolve and we expect that no stockholder or group of stockholders will control the outcome of any matters submitted to the stockholders.

#### Exchange Agreements
We have entered into Exchange Agreements with the direct partners of the Partnership that entitles those partners (and certain permitted transferees thereof) to exchange their Class B units (together with an equal number of shares of Class B common stock), Class C units or Class D units, for shares of Class A common stock on a one-for-one basis or, at our election, for cash. The most recent such Exchange Agreement, which we refer to as the Class D Exchange Agreement, was entered into at the closing of the 2024 Exchange on May 31, 2024.

In addition, the Exchange Agreements provide that an owner does not have the right to exchange their Class B, Class C or Class D units if we determine that such exchange would be prohibited by law or regulation or would violate other agreements with the Company, the Partnership or any of their subsidiaries to which the Partnership unitholder is subject. We may impose additional restrictions on exchanges that we determine to be necessary or advisable so that the Partnership is not treated as a "publicly traded partnership" for U.S. federal income tax purposes.

The Exchange Agreements also provide for mandatory exchanges under certain circumstances set forth in the StepStone Limited Partnership Agreement, including upon any transfer of partnership units to a person other than in a qualified transfer (as defined therein) and upon failure to comply with or material breach of the Stockholders Agreement.

Any beneficial holder exchanging Class B units must ensure that the applicable corresponding number of shares of Class B common stock are delivered to us for redemption at par value and cancellation as a condition of exercising its right to exchange Class B units for shares of our Class A common stock.

The Class D Exchange Agreement restricts the transfer of the Class D Units of the Partnership, which restriction shall apply for a maximum of one year after each exchange event (or two years if a Transaction Agreement Exchange (as defined in the Class D Exchange Agreement) constitutes an Acceleration Exchange (as defined in the Class D Exchange Agreement)), subject to certain exceptions.

#### Registration Rights Agreement
We have entered into a Registration Rights Agreement with certain former, current and future holders of our Class B, Class C and Class D units. This agreement provides these holders with certain registration rights, whereby they have the right to require us to register under the Securities Act the shares of Class A common stock issuable upon exchange of Class B, Class C or Class D units. The Registration Rights Agreement also provides for piggyback registration rights for the holders party thereto, subject to certain conditions and exceptions. The most recent amendment and restatement of the Registration Rights Agreement, which added Class D unitholders as parties, occurred in connection with the closing of the 2024 Exchange on May 31, 2024.

#### Indemnification Agreements
Our amended and restated bylaws provide that we will indemnify our directors and officers to the fullest extent permitted by the Delaware General Corporation Law ("DGCL"), subject to certain exceptions contained in our amended and restated bylaws. In addition, our amended and restated certificate of incorporation provides that our directors will not be liable for monetary damages for breach of fiduciary duty.

We have entered into indemnification agreements with each of our executive officers and directors. The indemnification agreements provide the executive officers and directors with contractual rights to indemnification, and expense advancement and reimbursement, to the fullest extent permitted under the DGCL, subject to certain exceptions contained in those agreements.

There is no pending litigation or proceeding naming any of our directors or officers to which indemnification is being sought, and we are not aware of any pending litigation that may result in claims for indemnification by any director or officer.

#### BENEFICIAL OWNERSHIP OF SECURITIES
The following table sets forth information as of June 30, 2025 (or as of the date otherwise indicated below) regarding beneficial ownership by:

• each person known to us to beneficially own more than 5% of any class of our outstanding common stock;

• our directors and director nominees;

• each of our named executive officers (as listed in the Summary Compensation Table above); and

• all of our directors and executive officers as a group.

Unless otherwise noted, the mailing address of each listed beneficial owner is c/o StepStone Group Inc., 277 Park Avenue, 45<sup>th</sup> Floor, New York, New York 10172.

The number of shares beneficially owned by each entity or individual is determined under the SEC rules, and the information is not necessarily indicative of beneficial ownership for any other purpose. Under such rules, beneficial ownership includes any shares as to which the entity or individual has sole or shared voting or investment power and also any shares that the entity or individual has the right to acquire as of August 29, 2025 (60 days after June 30, 2025) through the exercise of any stock options, through the vesting/settlement of RSUs payable in shares, or upon the exercise of other rights. Beneficial ownership excludes options or other rights vesting after August 29, 2025. Unless otherwise indicated, each person has sole voting and investment power (or shares such power with his or her spouse, as applicable) with respect to the shares set forth in the following table.

The number of shares of Class A common stock listed in the table below represents shares of Class A common stock directly owned, and assumes no exchange of Class B, Class C or Class D units for Class A common stock. As described in "—Related Person Transactions—Transactions in Connection with our Reorganization and Initial Public Offering—Exchange Agreement," each Class B unitholder, Class C unitholder and Class D unitholder is entitled to have its Class B units, Class C units or Class D units, as applicable, exchanged for Class A common stock on a one-for-one basis, or, at our option, for cash. As discussed in "—Related Person Transactions—Transactions in Connection with our Reorganization and Initial Public Offering—Stockholders Agreement," certain Class A and Class B stockholders who are employees and partners entered into a Stockholders Agreement pursuant to which they agreed to vote all their shares of voting stock, including Class A common stock and Class B common stock, together and in accordance with the instructions of the Class B Committee on any matter submitted to our common stockholders for a vote. Because they are a "group" under applicable securities laws, certain parties to the Stockholders Agreement may be deemed to be a beneficial owner of all securities held by the parties to the Stockholders Agreement.

##### [**Table of Contents**](#toc)
The number of shares of Class A common stock and Class B common stock outstanding and percentage of beneficial ownership set forth below is computed on the basis of 78,552,912 shares of our Class A common stock and 39,504,186 shares of our Class B common stock issued and outstanding as of June 30, 2025.

#### QUESTIONS & ANSWERS ABOUT THE ANNUAL MEETING
This proxy statement is being provided to you in connection with the solicitation of proxies by our board of directors of the Company for use at the Annual Meeting to be held on Tuesday, September 9, 2025 at 1:00 p.m. Eastern Time, or at any adjournments or postponements thereof.

**1.** **Where is the Annual Meeting being held?** 

Our board of directors has determined that the Annual Meeting should be held online via live audio webcast at <u>www.proxydocs.com/STEP</u> in order to permit stockholders from any location with access to the Internet to participate. See "—How can I attend, participate in and vote at the Annual Meeting online?" below for details.

**2.** **What proposals will be addressed at the Annual Meeting?** 

Stockholders will be asked to consider the following proposals at the Annual Meeting:

1. To elect the nine director nominees named in this proxy statement, each to serve for a one-year term and until his or her successor has been duly elected and qualified, or until his or her earlier death, resignation, removal, retirement or disqualification (Proposal 1);

2. To ratify the appointment of Ernst & Young LLP as the Company's independent registered public accounting firm for the fiscal year ending March 31, 2026 (Proposal 2);

3. To approve, on a non-binding and advisory basis, the compensation of our named executive officers ("Say-on-Pay");

4. To approve the Exculpation Amendment Proposal (Proposal 4);

5. To approve the Clean-Up Amendments Proposal (Proposal 5).

Additionally, stockholders are entitled to vote on such other business as may properly be presented at the Annual Meeting or any adjournment or postponement thereof. We are not aware of any matters to be voted on by stockholders at the Annual Meeting other than those included in these proxy materials. If any matter is properly presented at the Annual Meeting, your executed proxy gives your proxy holder discretionary authority to vote your shares in accordance with their best judgment with respect to the matter.

**3.** **Who can vote at the Annual Meeting?** 

Stockholders of record as of the close of business on July 15, 2025, the record date, are entitled to participate in and vote at the Annual Meeting. Pursuant to our amended and restated certificate of incorporation (the "certificate of incorporation"), holders of our (i) Class A common stock are entitled to one vote per share on all matters submitted to a vote of stockholders; and (ii) Class B common stock are entitled to five votes per share on all matters submitted to a vote of stockholders. Holders of our Class A common stock and Class B common stock will vote as a single class on all matters described in this proxy statement, except for Proposal 5, which requires an additional separate class vote of Class B common stock. Upon the occurrence of a Sunset on September 18, 2025, the voting rights of the Class B common stock will change to one vote per share.

As of the record date, there were 78,552,912 shares of our Class A common stock and 39,504,186 shares of our Class B common stock issued and outstanding. Pursuant to our certificate of incorporation, holders of Class A and Class B common stock are not entitled to cumulative voting.

**4.** **What is the difference between a stockholder of record and a beneficial owner of shares held in street name?** 

• *Stockholder of Record.* If (i) your shares of Class A common stock are registered directly in your name with the Company's transfer agent, Equiniti Trust Company, LLC (formerly, American Stock Transfer & Trust Company LLC), or (ii) you hold shares of Class B common stock, you are considered

------

##### [**Table of Contents**](#toc)
the stockholder of record with respect to those shares, and the proxy materials were sent directly to you by the Company.

• *Beneficial Owner of Shares Held in Street Name.* If your shares of Class A common stock are held in an account at a brokerage firm, bank, dealer, custodian or other similar organization acting as nominee (each referred to as a "broker"), then you are the beneficial owner of shares held in "street name," and the proxy materials were forwarded to you by that organization. The organization holding your account is considered the stockholder of record for purposes of voting at the Annual Meeting. As a beneficial owner, you have the right to instruct that organization on how to vote the shares held in your account by following the instructions that the organization provides to you with the proxy materials. Those instructions are contained in a "voting instruction form."

**5.** **How can I attend, participate in and vote at the Annual Meeting online?** 

Stockholders of record and beneficial owners of shares of our common stock as of the record date may attend and participate in the Annual Meeting, including voting and asking questions during the virtual Annual Meeting, by registering in advance of the Annual Meeting at <u>www.proxydocs.com/STEP</u>.

The Annual Meeting will begin at 1:00 p.m. Eastern Time on Tuesday, September 9, 2025.

Upon completing your registration, you will receive further instructions via email, including a unique link that will allow you access to the Annual Meeting and to vote and submit questions during the Annual Meeting. As part of the registration process, you must enter the control number located on your proxy card, voting instruction form, or Notice. If you are a beneficial owner of shares registered in the name of a broker, bank or other nominee, you will also need to enter your uniquely assigned control number at <u>www.proxydocs.com/STEP</u> as part of the registration process; alternatively, if you do not have a control number, please contact your broker, bank or other nominee as soon as possible and no later than September 2, 2025, so that you can be provided with a control number and gain access to the meeting.

If you were a stockholder as of the close of business on July 15, 2025, the record date, you may vote shares held in your name as the stockholder of record or shares for which you are the beneficial owner but not the stockholder of record electronically during the Annual Meeting through the online virtual annual meeting platform by following the instructions provided when you log onto the online virtual Annual Meeting platform.

Before the Annual Meeting beneficial owners may vote by following the instructions on their voting instruction form, and stockholders of record may vote:

• By mail, by completing, signing, and dating your proxy card (if applicable).

------

##### [**Table of Contents**](#toc)
**6.** **How does the board of directors recommend that I vote?** 

Our board of directors recommends that stockholders vote "**FOR**" each nominee for director named in Proposal 1; "**FOR**" the ratification of the selection of Ernst & Young LLP as our independent registered public accounting firm for the fiscal year ending March 31, 2026 (Proposal 2); "**FOR**" the approval, on a non-binding and advisory basis, of the compensation of our named executive officers (Proposal 3); "**FOR**" the approval of the Exculpation Amendment Proposal (Proposal 4); and "**FOR**" the approval of the Clean-Up Amendments Proposal (Proposal 5).

**7.** **How many votes must be present to hold the Annual Meeting?** 

In order for us to conduct the Annual Meeting, a quorum, consisting of a majority of the voting power of the stock outstanding and entitled to vote at the Annual Meeting, must be present or represented by proxy. Abstentions and withhold votes are counted as "shares present" at the Annual Meeting for purposes of determining whether a quorum exists. Proxies submitted by brokers or other holders of record holding shares for you as a beneficial owner that do not indicate a vote for some or all of the proposals because that holder does not have voting authority and has not received voting instructions from you (so-called "broker non-votes") are also considered "shares present" for purposes of determining whether a quorum exists. If you are a beneficial owner, these holders may in some cases vote your shares in their discretion, but are not permitted to vote on certain proposals and may elect not to vote on any of the proposals unless you provide voting instructions.

**8.** **What is a proxy card?** 

The proxy card enables you to appoint Jason Ment, Jose Fernandez and Jennifer Ishiguro as your representatives at the Annual Meeting. By completing and returning the proxy card, you are authorizing such persons to vote your shares at the Annual Meeting in accordance with your instructions on the proxy card. This way, your shares will be voted whether or not you attend the Annual Meeting. Even if you plan to attend the Annual Meeting, it is strongly recommended that you complete and return your proxy card before the date of the Annual Meeting in case your plans change. If a proposal comes up for vote at the Annual Meeting that is not on the proxy card, the proxies will vote your shares, under your proxy, according to their best judgment.

**9.** **Will my shares be voted if I do not provide my proxy?** 

If you hold your shares directly in your own name, they will not be voted if you do not provide a proxy.

Your shares may be voted under certain circumstances if they are held in the name of a broker. Brokers generally have the authority, but are not required, to vote shares not voted by customers on certain "routine" matters, and are prohibited from exercising discretionary authority on non-routine matters. Whether a proposal is considered routine or non-routine is subject to stock exchange rules and final determination by the stock exchange. Because the ratification of an independent registered public accounting firm (Proposal 2) is the only matter that we expect to be considered to be "routine" at the Annual Meeting, your shares may only be voted by your broker for the ratification of our independent registered public accounting firm. However, even with respect to routine matters, some brokers are choosing not to exercise discretionary voting authority. We expect that there will be no broker non-votes (as described above) with respect to Proposal 2. Broker non-votes, if any, will have no effect on the outcome of the vote in Proposals 1 and 3 and will have the same effect as a vote against for Proposals 4 and 5.

As mentioned above, in the case of broker non-votes, if any, those shares will still be counted for purposes of determining if a quorum is present.

**10.** **What vote is required to elect directors (Proposal 1)?** 

Directors are elected by a plurality of the votes cast at the Annual Meeting. As a result, the nine nominees who receive the highest number of shares voted "For" his or her election will be elected.

------

##### [**Table of Contents**](#toc)
"Withhold" votes against a director and broker non-votes, if any, will have no direct effect on his or her election. However, our board has adopted a director resignation policy, under which any director who receives a greater number of votes "withheld" for his or her election than "for" such election is expected to promptly tender his or her resignation offer to the Nominating and Corporate Governance Committee. The Nominating and Corporate Governance Committee will recommend to our board whether to accept or reject the resignation offer, or whether other action should be taken. In determining whether to recommend that our board accept any resignation offer, the Nominating and Corporate Governance Committee may consider all factors that the Committee's members believe are relevant. Our board will act on the Nominating and Corporate Governance Committee's recommendation within 90 days following certification of the election results. Any director who tenders his or her resignation offer will not participate in the proceedings of either the Nominating and Corporate Governance Committee or our board with respect to his or her own resignation offer.

**11.** **What vote is required for Proposal 2?** 

Approval of Proposal 2 requires the affirmative vote of at least a majority of the voting power of the stock present or represented by proxy and entitled to vote on the subject matter, voting as a single class.

Abstentions will have the same effect as a vote "Against" on the outcome of Proposal 2. Because broker discretionary voting is expected to be permitted with respect to Proposal 2, we expect there will be no broker non-votes with respect to Proposal 2.

**12.** **What vote is required for Proposal 3?** 

Approval of Proposal 3 requires the affirmative vote of at least a majority of the voting power of the stock present or represented by proxy and entitled to vote on the subject matter, voting as a single class.

Abstentions will have the same effect as a vote "Against" on the outcome of Proposal 3, and broker non-votes, if any, will have no effect on Proposal 3.

**13.** **What vote is required for Proposal 4?** 

Approval of Proposal 4 requires the affirmative vote of the holders of at least a majority of the voting power of the outstanding stock entitled to vote on the subject matter, voting as a single class.

Abstentions and broker non-votes, if any, will have the same effect as a vote "Against" on the outcome of Proposal 4 .

**14.** **What vote is required for Proposal 5?** 

Approval of Proposal 5 requires the affirmative vote of the holders of (i) at least a majority of the voting power of the outstanding stock entitled to vote on the subject matter, voting as a single class, and (ii) at least a majority of the outstanding shares of Class B common stock, voting as a separate class.

Abstentions and broker non-votes, if any, will have the same effect as a vote "Against" on the outcome of Proposal 5.

**15.** **Can I change my vote after I have voted?** 

You may revoke your proxy and change your vote at any time before the final vote at the Annual Meeting. You may revoke your previously delivered proxy and vote again by signing and returning a new proxy card or voting instruction form with a later date or by attending the Annual Meeting online and voting. Your attendance at the Annual Meeting online will not automatically revoke your proxy unless you vote at the Annual Meeting or

------

##### [**Table of Contents**](#toc)
specifically request that your prior proxy be revoked by delivering to the Company's Chief Legal Officer & Secretary at 277 Park Avenue, 45th Floor, New York, New York 10172 a written notice of revocation prior to the Annual Meeting.

Please note, however, that if your shares are held of record by a broker, you must instruct your broker, bank or other nominee that you wish to change your vote by following the procedures on the voting form provided to you by the broker, bank or other nominee.

**16.** **What happens if I do not indicate how to vote my proxy?** 

If you sign your proxy card without providing further instructions, your shares will be voted "**FOR**" each of the director nominees (Proposal 1); "**FOR**" the ratification of the selection of Ernst & Young LLP as our independent registered public accounting firm for the fiscal year ending March 31, 2026 (Proposal 2); "**FOR**" the approval, on a non-binding and advisory basis, of the compensation of our named executive officers (Proposal 3); "**FOR**" approval of the Exculpation Amendment Proposal (Proposal 4); and "**FOR**" approval of the Clean-Up Amendments Proposal (Proposal 5).

**17.** **Where do I find the voting results of the Annual Meeting?** 

The final voting results will be tallied by the inspector of election and published in the Company's Current Report on Form 8-K, which the Company will file with the SEC within four business days following the Annual Meeting.

**18.** **Who bears the cost of soliciting proxies?** 

The Company will bear the cost of soliciting proxies in the accompanying form and will reimburse brokerage firms and others for expenses involved in forwarding proxy materials to beneficial owners or soliciting their execution. In addition to solicitations by mail, the Company, through its directors and officers, may solicit proxies in person, by telephone or by electronic means. Such directors and officers will not receive any special remuneration for these efforts.

#### OTHER MATTERS

#### Other Business
We are not currently aware of any business to be acted upon at the Annual Meeting other than the matters discussed in this proxy statement. The form of proxy accompanying this proxy statement confers discretionary authority upon the named proxy holders with respect to amendments or variations to the matters identified in the accompanying Notice of Annual Meeting and with respect to any other matters which may properly come before the Annual Meeting or any adjournment or postponement thereof. If other matters do properly come before the Annual Meeting, or at any such adjournment or postponement of the Annual Meeting, we expect that shares of our common stock represented by properly submitted proxies will be voted by the proxy holders in accordance with the recommendations of our board.

#### Submission of Stockholder Proposals for the 2026 Annual Meeting
*Rule 14a-8 Proposals.* For any proposal to be considered for inclusion in our proxy statement and form of proxy for submission to the stockholders at our 2026 Annual Meeting of Stockholders, it must be submitted in writing and comply with the requirements of Rule 14a-8 of the Exchange Act. Such proposals must be received by the Company by email at <u>shareholders@stepstonegroup.com</u> or in writing, c/o our Chief Legal Officer & Secretary, at StepStone Group Inc., 277 Park Avenue, 45th Floor, New York, New York 10172 no later than the close of business on March [ ], 2026.

*Advance Notice Proposals and Nominations.* In addition, our bylaws provide notice procedures for stockholders to nominate a person as a director and to propose business to be considered by stockholders at an Annual Meeting of Stockholders (but not for inclusion in the proxy statement). Notice of a nomination or other proposal of business must be delivered to the Company by email at <u>shareholders@stepstonegroup.com</u> or in writing, c/o our Chief Legal Officer & Secretary, at StepStone Group Inc., 277 Park Avenue, 45th Floor, New York, New York 10172 no later than the close of business on the 90th day, nor earlier than the close of business on the 120th day, prior to the first anniversary of the preceding year's annual meeting; provided, however, that in the event that the date of the annual meeting is more than 30 days before or more than 30 days after such anniversary date, to be timely notice by the stockholder must be so delivered not earlier than the close of business on the 120th day prior to such annual meeting and not later than the close of business on the later of (i) the 90th day prior to such annual meeting or (ii) the 10th day following the day on which public announcement of the date of the annual meeting is first made by us. Accordingly, for our 2026 Annual Meeting of Stockholders, notice of a nomination or proposal must be delivered to us no earlier than the close of business on May 12, 2026 and no later than the close of business on June 11, 2026. Nominations and proposals also must satisfy other requirements set forth in the bylaws (which includes information required under Rule 14a-19).

For purposes of these proposals, "close of business" shall mean 6:00 p.m. local time at the principal executive offices of the Company on any calendar day, whether or not the day is a business day.

#### Householding Information
Unless we have received contrary instructions, we may send a single copy of the Notice or this proxy statement to any household at which two or more stockholders reside. This process, known as "householding," reduces the volume of duplicate information received at any one household, helps to reduce our expenses, and benefits the environment. However, if stockholders prefer to receive multiple sets of our disclosure documents at the same address this year or in future years, the stockholders should follow the instructions described below. Similarly, if an address is shared with another stockholder and together, both of the stockholders would like to receive only a single set of our disclosure documents, the stockholders should follow these instructions: If the shares are registered in the name of the stockholder, the stockholder should notify us by email at <u>shareholders@stepstonegroup.com</u>, by phone at 212.351.6100 or in writing, c/o our Chief Legal Officer & Secretary, at StepStone Group Inc., 277 Park Avenue, 45th Floor, New York, New York 10172 to inform us of his or her request. If a broker holds the shares, the stockholder should contact such broker directly.

Upon notice from the Partnership of such an Anti-Dilution Event, the Corporation shall issue a number of shares of Class B Common Stock registered in the name of the applicable holder equal to the number of Class B Units issued in connection with such Anti-Dilution Event, in exchange for payment in cash to the Corporation of the aggregate par value of the shares of Class B Common Stock so issued.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) If any outstanding share of Class B Common Stock shall cease to be held by a concurrent holder of a Class B Unit (including a transferee of a Class B Unit), such share shall automatically and without further action on the part of the Corporation or any holder of Class B Common Stock be transferred to the Corporation and upon such transfer shall be automatically retired and shall thereupon be restored to the status of an authorized but unissued share of Class B Common Stock of the Corporation.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) Except as may be otherwise provided with respect to directors elected by the separate vote of the holders of one or more series of Preferred Stock (the "<u>Preferred Stock Directors</u>"), the Board of Directors shall be divided into three classes, designated Class I, Class II and Class III. The Board of Directors shall have the exclusive power to fix the number of directors in each class. Class I directors shall initially serve until the first annual meeting of stockholders following the closing of the Corporation's IPO, and director nominees elected to succeed such Class I directors as Class I directors will be elected to hold office for a three-year term and until the election and qualification of their respective successors in office or until any such director's earlier death, resignation, removal, retirement or disqualification.

Class III directors shall initially serve until the third annual meeting of stockholders following the closing of the Corporation's IPO.

In case of any increase or decrease, from time to time, in the number of directors (other than Preferred Stock Directors), the number of directors in each class shall be fixed solely by the Board of Directors as determined solely by the Board of Directors. The Board of Directors is authorized to assign members of the Board of Directors already in office to Class I, Class II or Class III.

Any director so chosen shall hold office until the next election of the class for which such director shall have been chosen and until his or her successor shall have been duly elected

and qualified or until any such director's earlier death, resignation, removal, retirement or disqualification. Notwithstanding the foregoing, from and after the final adjournment of the third annual meeting of stockholders following the closing of the Corporation's IPO, a<u>A</u>ny director so chosen shall hold office until the next election of directors and until his or her successor shall have been duly elected and qualified or until any such director's earlier death, resignation, removal, retirement or disqualification. No decrease in the authorized number of directors shall shorten the term of any incumbent director.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) Any director (other than any Preferred Stock Director) may be removed from office at any time, but only for cause and only by the affirmative vote of at least a majority of the voting power of the stock outstanding and entitled to vote thereon; provided, however, that from and after the final adjournment of the third annual meeting of stockholders following the closing of the Corporation's IPO, any such director who is elected for a one-year term may be removed with or without cause but only by the affirmative vote of at least 66<sup>2</sup>⁄<sub>3</sub>% of the voting power of the stock outstanding and entitled to vote thereon. Notwithstanding the foregoing, whenever the holders of any class or series are entitled to elect one or more directors by this Restated Certificate of Incorporation (including any Preferred Stock Designation), with respect to the removal without cause of a director or directors so elected, the vote of the holders of the outstanding shares of that class or series and not the vote of the outstanding shares as a whole shall apply.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) During any period when the holders of one or more series of Preferred Stock have the separate right to elect additional directors as provided for or fixed pursuant to the provisions of Article IV hereof (including any Preferred Stock Designation), and upon commencement and for the duration of the period during which such right continues: (i) the then otherwise total authorized number of directors of the Corporation shall automatically be increased by such number of directors that the holders of any series of Preferred Stock have a right to elect, and the holders of such Preferred Stock shall be entitled to elect the additional directors so provided for or fixed pursuant to said provisions; and (ii) each Preferred Stock Director shall serve until such Preferred Stock Director's successor shall have been duly elected and qualified, or until such director's right to hold such office terminates pursuant to said provisions, whichever occurs earlier, subject to his or her earlier death, disqualification, resignation or removal. Except as otherwise provided for or fixed pursuant to the provisions of Article IV hereof (including any Preferred Stock Designation), whenever the holders of one or more series of Preferred Stock having a separate right to elect additional directors cease to have or are otherwise divested of such right pursuant to said provisions, the terms of office of all Preferred Stock Directors elected by the holders of such series of Preferred Stock, or elected to fill any vacancies resulting from the death, resignation, disqualification or removal of such additional directors, shall forthwith terminate (in which case each such Preferred Stock Director shall cease to be qualified as a director and shall cease to be a director) and the total authorized number of directors of the Corporation shall be automatically reduced accordingly.
