###### STEPSTONE'S RESPONSIBLE INVESTMENT GOVERNANCE STRUCTURE

## Governance
###### Governance structure drives delivery on RI and corporate priorities across asset classes.

##### Climate change is a critical issue that requires strong governance systems, policies and procedures to manage effectively. At StepStone, we recognize

###### STEPSTONE BOARD

##### the need to integrate climate responsibility into our governance structures and have made it a priority across our entire business.

###### Our Board of Directors, as the highest governance body, plays a key role in overseeing the management of significant risks, including climate change. The board and its committees meet regularly to review the effectiveness of our processes and progress. ESG updates, including climate-related risks and opportunities, are a recurring item on the board's agenda. As part of our commitment to good governance, we established key milestones to enhance the board's oversight of ESG activities in 2022, including an annual strategic climate review aligned with TCFD guidelines.

###### To manage our responsible investment practices, including climate change considerations, we established the Responsible Investment (RI) Committee in 2013. The committee is responsible for the development and execution of our RI Policy, which guides our approach to assessing and integrating ESG topics, including climate change, across our global operations and investment process. The committee is chaired by our Global Head of Responsible Investment and comprises 15 members plus one observer, including our CEO and other leaders representing all asset classes. The committee is supported by five dedicated RI work groups, one for each asset class and one for corporate-level initiatives, to drive ESG and climate initiatives across our global business.

The Climate Policy, including the execution of the broader initiatives included within the policy, is under the purview of the Responsible Investment Committee, which is governed by a charter approved by the StepStone Board of Directors. The Responsible Investment Committee comprises senior professionals across asset classes, geographies, and functional areas within the firm. The Responsible Investment Committee through the Responsible Investment Workgroups for each asset class provides guidance on and leadership to the investment team on the implementation of climate change processes in investment activities. [...] StepStone's executive team regularly updates the StepStone Board of Directors on responsible investments matters, including climate change considerations, underscoring the commitment of leadership oversight on these issues. [...] This policy should be reviewed annually and updated as necessary. This policy should be reviewed by the Head of Responsible Investment and the Responsible Investment Committee. The Responsible Investment Committee includes three members of the Board of Directors of StepStone Group Inc.

StepStone looks to collaborate with industry working groups, contribute to organized collaborative engagement efforts, and engage directly with policymakers through consultation processes where relevant. Efforts include providing formal letters of support and feedback on policy/regulatory issues. Further, StepStone is proud to have collaborated with many industry working groups who, in turn, work directly with policymakers. StepStone is a part of the PRI EU Taxonomy Workgroup, PRI Global Policy Reference Group, Invest Europe Workgroups on Non-Financial Reporting Directive ('NFRD') and Sustainable Finance Disclosure Regulation ('SFDR'), the PRI LP ESG Due Diligence Questionnaire ('DDQ') Working Group, the Institutional Investors Group on Climate Change ('IIGCC') Private Equity and Infrastructure Workgroups, and the LP-GP Disclosure Workgroup of Initiative Climat International ('iCI'). In 2022, StepStone was appointed to the PRI's Private Equity Advisory Committee. Through these stewardship channels, StepStone hopes to influence new policy and work toward creating positive change in private markets and beyond. [...] StepStone's Responsible Investment governance structure provides oversight of any engagement or public position to ensure alignment with the values of the Firm and the objectives as stated in its Responsible Investment Policy.
