Atomico Advisors IV, Ltd. is the general partner of Atomico IV L.P. and Atomico IV (Guernsey), L.P.    Percentage ownership is based on 80,597,784 total shares of Class A Common Stock, Class B Common Stock, and Series E Preferred Stock outstanding immediately following the Issuer's initial public offering on May 23, 2025, as reported in the Issuer's final prospectus filed with the Securities and Exchange Commission on May 23, 2025 pursuant to Rule 424(b)(4) of the Securities Act of 1933 (the "424B4 Prospectus").

The Class B Common Stock will be convertible into shares of Class A Common Stock on a one-to-one basis at any time at the option of the holder upon written notice to the Issuer.  In addition, the Class B Common Stock will automatically convert into shares of Class A Common Stock immediately prior to the close of business on the earliest to occur of certain events specified in the Issuer's Amended and Restated Certificate of Incorporation.

Each share of Class A Common Stock is entitled to one vote and each share of Class B Common Stock is entitled to fifteen votes.  There were 53,266,406 shares of Class B Common Stock outstanding as of May 23, 2025, as reported in the 424B4 Prospectus.  The percentage reported does not reflect the fifteen for one voting power of the Class B Common Stock because these shares are treated as converted into Class A Common Stock for the purpose of this report.
