Explanation of responses
- F1The Series Seed-1 Preferred Stock, Series A Preferred Stock, and Series A-2 Preferred Stock automatically converted into Class A Common Stock of the Issuer on a 1-for-1 basis immediately prior to the closing of the Issuer's initial public offering. The securities had no expiration date.
- F2Fundomo SN-001 GP, LLC ("SN-001 GP") is the sole general partner of Fundomo SN-001, LP ("SN-001"). Fundomo SN-002 GP, LLC ("SN-002 GP") is the sole general partner of Fundomo SN-002, LP ("SN-002"). Corey Nobile is the sole member of SN-001 GP and SN-002 GP. Each of SN-001 GP, SN-002 GP, and Corey Nobile may be deemed to share voting and dispositive power with respect to the shares held directly by SN-001 (in the case of SN-001 GP) and SN-002 (in the case of SN-002 GP), respectively.
- F3ST-1014 Fund I, a series of Fundomo Syndicates, LP ("ST-1014 Fund I") may be considered an affiliate of SN-001, SN-002, SN-001 GP and SN-002 GP, but voting and dispositive power over the shares held directly by ST-1014 Fund I has been delegated on an irrevocable basis to an unaffiliated third-party investment adviser pursuant to the terms of ST-1014 Fund I's limited partnership agreement, and none of the reporting persons named herein has voting or dispositive power over such shares.
- F4Each of the reporting persons and entities disclaims beneficial ownership of the reported securities (except to the extent of such person's or entity's pecuniary interest in such securities). The filing of this statement by the reporting persons shall not be deemed an admission that such persons are, for purposes of Section 16 of the Securities and Exchange Act of 1934 or otherwise, the beneficial owner of any equity securities covered by this statement.
- F5The Form 4 filed on July 21, 2026 is amended herein to correct a clerical error in Box 5 of Table II. Consistent with the disposition of the underlying preferred stock upon its conversion into Class A Common Stock as described in the accompanying footnotes, the number of derivative securities disposed of should have been entered under the "(D)" column in Box 5, but was inadvertently reported under the "(A)" column. The Form 4 remains otherwise unmodified.
