### Footnotes:

(1) The Issuer at the time of the original underlying Form 4 filling was P10, Inc. (trading symbol "PX"). Effective February 11, 2026, P10, Inc. changed its name to Ridgepost Capital, Inc. and its trading symbol to "RPC". This filing reflects the name of the Issuer as of the filing date, May 6, 2026.

(2) After the conversion by TrueBridge Colonial on March 19, 2025 of 1,304,161 shares of Class B common stock into an equivalent number of shares of Class A common stock, 391,248 shares of Class A common stock were transferred to the Poston Trust. This transaction was exempt from Section 16 reporting under Rule 16a-13, but is reported here for illustrative purposes per note 3 herein and to further reflect that the Poston Trust has directly owned 912,913 shares of Class A common stock since March 19, 2025.

(3) This Form 4 Amendment is to correct the number of shares reported as beneficially owned by TrueBridge Colonial Fund, U/A dated 11/15/2015 ("TrueBridge Colonial"), as of the date of the earliest transaction to be reported, March 19, 2025. The correct amount of Class A common stock beneficially owned by TrueBridge Colonial following transactions on March 19, 2025 was 2,282,282 (after rounding). The correct amount of Class A common stock beneficially owned by the Edwin A. Poston Revocable Trust (the "Poston Trust") following transactions on March 19, 2025 was 912,913 (after rounding). These differences are attributable to the transaction described in note 2 herein.

(4) Represents securities of the Issuer owned directly and indirectly by TrueBridge Colonial. First Republic Trust Company of Delaware, as trustee of TrueBridge Colonial, may be deemed to beneficially own the securities of the Issuer owned directly and indirectly by TrueBridge Colonial. Mr. Poston disclaims beneficial ownership of the securities of the Issuer reported herein, except to the extent of his pecuniary interest therein, and the filing of this Form 4 shall not be construed as an admission that the Reporting Person is a beneficial owner of the securities of the Issuer reported herein.

(5) Represents securities of the Issuer owned directly by the Poston Trust. Mr. Poston, as sole trustee of the Poston Trust, may be deemed to beneficially own the securities of the Issuer owned indirectly by TrueBridge Colonial. Mr. Poston disclaims beneficial ownership of the securities of the Issuer reported herein, except to the extent of his pecuniary interest therein, and the filing of this Form 4 shall not be construed as an admission that the Reporting Person is a beneficial owner of the securities of the Issuer reported herein.

**Remarks:**
This Form 4 is being filed on behalf of Edwin A. Poston (the "Reporting Person"). At the time of the original filing, the Reporting Person was a Member of 10% Owner Group. At the time of the original filing, the Reporting Person may be deemed to be a member of a Section 13(d) group that collectively beneficially owns more than 10% of the Issuer's Common Stock. The securities reported herein do not include securities of the Issuer held by any other group member other than those securities held directly or indirectly by the Reporting Person. In addition, the Reporting Person serves as a director on the board of directors of the Issuer.
