The RSU awards identified above were made by the Committee through the use of the form of RSU award agreement that was approved by the Committee on November 12, 2024, described in the Company’s Form 8-K filed with the Securities and Exchange Commission (the “SEC”) on November 18, 2024 and filed as Exhibit 10.50 to the Company’s Form 10-Q filed with the SEC on February 7, 2025 (the “RSU Form”). Each of the RSU awards will be settled in shares of Post common stock and vests in equal installments on the first, second and third anniversaries of the date of grant, subject to continued employment and to certain acceleration events as described in the award agreements. The foregoing description of the terms of these RSU awards does not purport to be complete and is qualified in its entirety by reference to the full text of the RSU Form previously filed with the SEC, which is incorporated herein by reference.

The PRSU awards identified above were made by the Committee through the use of the form of PRSU award agreement that was approved by the Committee on November 12, 2024, described in the Company’s Form 8-K filed with the SEC on November 18, 2024 and filed as Exh ibit 10.52 to the Company’s Form 10-Q filed with the SEC on February 7, 2025 (the “PRSU Form”). The performance period for the PRSUs is from October 1, 2025 to September 30, 2028. The performance metric for these PRSUs is the Company’s total shareholder return (“TSR”) ranking compared to the TSR rankings of peer companies over a three-year period, with the following percentage vesting schedule:


Relative TSR Percentile Rank			Vesting Percentage (of Target)
≥85th			260%
75th			200%
50th			100%
25th			50%
<25th			0%

Vesting of the PRSUs would accelerate, in whole or in part, in certain events, as described in the award agreements. The PRSUs will be settled in shares of Post common stock, cash or other consideration, in each case, based on the fair market value of Post common stock on the applicable vesting date, in the discretion of the Committee. The foregoing description of the terms of these PRSUs does not purport to be complete and is qualified in its entirety by reference to the full text of the PRSU Form previously filed with the SEC, which is incorporated herein by reference.
