Explanation of Responses:
1. Class B ordinary shares (the "Initial Shares") were issued in a private placement to the Initial Shareholders of NorthStrive Acquisition Corp I. (the "Company") prior to the Company's initial public offering. Each Class B ordinary share will automatically convert into one Class A ordinary share at the time of the Company's initial Business Combination (or earlier at the option of the holder), on a one-for-one basis, subject to adjustment, as described in the Company's Amended and Restated Memorandum and Articles of Association and the final prospectus for the Company's initial public offering (File No. 333-297611).
2. On October 20, 2026, NorthStrive Sponsor I LLC (the "Sponsor") forfeited and surrendered 325,607 Class B ordinary shares to the Company for cancellation, for no consideration, pursuant to Section 1.4.1 of the Underwriting Agreement, dated August 17, 2026, between the Company and D. Boral Capital LLC, as representative of the several underwriters therein, as amended by Amendment No. 1 to Underwriting Agreement, dated as of October 8, 2026, (the "UA Amendment"). The cancellation became effective on October 20, 2026, with retroactive effect to October 3, 2026. The UA Amendment implements the pro rata allocation of the 629,998-share forfeiture required because the underwriters' Over-allotment Option expired unexercised on October 3, 2026. The Sponsor's share of that forfeiture (325,607 Initial Shares) was calculated pro rata based on the Initial Shares held by the Sponsor relative to the aggregate Initial Shares outstanding as set forth in Exhibit A to the UA Amendment.
3. The securities are held directly by the Sponsor. PMGC Holdings Inc. ("PMGC") is the sole member of the Sponsor and holds all membership interests and voting power of the Sponsor and, as a result, may be deemed to beneficially own the securities held by the Sponsor. Each Reporting Person disclaims beneficial ownership of the reported securities except to the extent of its pecuniary interest therein.
