Explanation of Responses:

( 1 )Prior to the Business Combination (as defined below), the Class B ordinary shares were convertible into Class A ordinary shares on a one-for-one basis (subject to certain anti-dilution adjustments) and had no expiration date. ( 2 )As described in the registration statement on Form S-4 (File No. 333-261820) of Apollo Strategic Growth Capital ("APSG"), now known as Global Business Travel Group, Inc. ("GBT"), the Class B ordinary shares of APSG held by the reporting person automatically converted into an equal number of shares of Class X common stock of GBT upon APSG's domestication into a Delaware corporation and immediately thereafter automatically converted into an equal number of shares of Class A common stock of GBT upon the closing of the business combination with GBT JerseyCo Limited (the "Business Combination").

Remarks: As a result of the Business Combination, the reporting person has ceased to be a director of the Issuer.

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