Explanation of Responses:

( 1 )As a result of affiliates of Welsh Carson owning less than 5% of the Issuer's common stock on June 12, 2025, the reported shares of Class C Common Stock, which were previously distributed to the Reporting Person by WCAS XIII Associates LLC in pro rata distributions to its members for no consideration that were exempt from reporting pursuant to Rule 16a-9 (the "Distributions"), automatically converted into an equal number of shares of Class B Common Stock (the "Conversion"), of which 159,063 shares of Class B Common Stock are held directly by the Reporting Person and 81,066 shares of Class B Common Stock are held by The D. Scott Mackesy 2014 Irrevocable Descendants Trust. Shares of Class B Common Stock, which are entitled to one vote per share, do not represent economic interests in the Issuer. ( 2 )The reported securities, which were previously received by the Reporting Person in the Distributions, consist of 197,092 shares of Class A Common Stock held directly by the Reporting Person and 108,029 shares of Class A Common Stock held by The D. Scott Mackesy 2014 Irrevocable Descendants Trust. ( 3 )The Reporting Person may exchange all or a portion of such person's common units of CWAN Holdings, LLC ("LLC Interests") (together with the delivery for no consideration of an equal number of shares of Class B Common Stock) for an equal number of newly issued shares of Class A Common Stock from time to time, subject to customary adjustments, or, at the election of the Issuer, a cash payment equal to the 20 day volume weighted average price of shares of Class A Common Stock immediately prior to the applicable exchange date. ( 4 )The reported securities, which were previously received by the Reporting Person in the Distributions, consist of 197,092 LLC Interests held directly by the Reporting Person and 108,029 shares of LLC Interests held by The D.
