Explanation of Responses:

( 1 )Each Restricted Stock Unit ("RSU") represents the contingent right to receive one share of Class A Common Stock of the Issuer. ( 2 )Represents a grant of RSUs under the Issuer's 2020 Incentive Award Plan on December 15, 2022. The RSUs will vest in full on March 31, 2023, subject to the Reporting Person's continued service on the vesting date. Delivery of Class A Common Stock in settlement of vested RSUs will occur on the delivery date set forth in the applicable award agreement unless the Issuer elects to settle the RSUs in cash, or a combination of Class A Common Stock and cash, in the Issuer's sole discretion. ( 3 )GCM Grosvenor Management, LLC ("GCM Grosvenor Management") awarded the Reporting Person interests (the "Management Award Interests") in GCM Grosvenor Management that represent the contingent right to receive shares of the Issuer's Class A Common Stock owned by GCM Grosvenor Management on a one-for-one basis on May 1, 2025. 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 Management Holdings, LLLP. ( 4 )Represents the grant of Management Award Interests on December 15, 2022. The award will vest in full on May 1, 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 award vests.

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