Explanation of Responses:

( 1 )GCM Grosvenor Management, LLC ("GCM Grosvenor Management") awarded interests (the "Management Award Interests") in GCM Grosvenor Management that represent the contingent obligation to transfer rights to shares of the Issuer's Class A Common Stock owned by GCM Grosvenor Management on a one-for-one basis to employees of the Issuer or its affiliates beginning in 2025. The Reporting Person is the ultimate managing member GCM Grosvenor Management. The Management Award Interests represent an obligation of GCM Grosvenor Management and do not constitute any new share issuance or obligation of the Issuer. GCM Grosvenor Management is obligated to transfer Class A Common Stock it owns, and therefore the vesting of Management Award Interests will not dilute the Issuer's Class A Common Stockholders relative to noncontrolling interests in Grosvenor Capital Managment Holdings, LLLP. ( 2 )Represents the disposition of Management Award Interests on December 15, 2022. The Management Award Interests will begin to vest in 2025. Delivery of shares of Class A Common Stock owned by GCM Grosvenor Management in settlement of vested Management Award Interests will occur in the year in which the awards vest. ( 3 )Represents securities held directly by GCM Grosvenor Management. The Reporting Person is the ultimate managing member GCM Grosvenor Management.

Reminder: Report on a separate line for each class of securities beneficially owned directly or indirectly.
