Footnotes from the filing
In accordance with the terms of the Plan, the vesting of the unvested RSUs granted on November 12, 2024, each of which represented a contingent right to receive one share of Post common stock on the applicable vesting date (either the second or third anniversary of the date of grant), accelerated as a result of the Reporting Person's retirement on January 2, 2026. The settlement of the remaining shares of Post common stock underlying the vested RSUs, reduced for the withholding of additional taxes due at that time, will occur following the six-month delay required under Section 409A of the IRC.
