Explanation of Responses:

1. In the reorganization (the "Reorganization") of StepStone Group LP (the "Partnership") in connection with the closing of the initial public offering ("IPO"), shares of Class B Common Stock of the Issuer, par value $0.001 per share, were issued without additional consideration in exchange for voting interests in the general partner of the Partnership. The Class B Common Stock does not carry economic value beyond the right to receive the par value of such stock upon liquidation, dissolution, winding up or an exchange of those shares. However, the Class B Common Stock entitles its holder to five votes per share on every matter submitted to the Issuer's stockholders for a vote until the occurrence of a sunset, as described in the Issuer's Amended and Restated Certificate of Incorporation.
