Filing notes and footnotes

Explanation of responses 3 footnotes

Footnote F1

Represents a grant of restricted stock units ("RSUs") granted pursuant to the P3 Health Partners Inc. 2021 Incentive Award Plan. Each RSU represents a right to receive one share of Class A common stock. The RSUs vest upon the earlier of the Company's 2026 annual stockholder meeting and the one-year anniversary of the grant date.

Footnote F2

This amended Form 4 is being filed to correct Column 5 of Table I, which inadvertently reported the number of securities beneficially owned by the Reporting Person prior to the Company's 1-for-50 reverse stock split, which became effective on April 11, 2025, and excluded certain securities indirectly owned by the Reporting Person. This amended Form 4 is being filed to correct the number of securities beneficially owned by the Reporting Person to reflect the reverse stock split, as well as the Reporting Person's indirect ownership.

Footnote F3

The Reporting Person and Nasrin Thierer have voting and dispositive power over the securities held by AssetBlue Ventures, LLC.
