F1	Surrender of shares in payment of tax withholding due as a result of the vesting of 4,347 restricted stock units ("RSUs") in accordance with Rule 16b-3.
F2	Each RSU represents a contingent right to receive one share of Post Holdings, Inc. common stock. The RSUs were granted under the Post Holdings, Inc. 2021 Long-Term Incentive Plan (the "2021 LTIP") in a transaction exempt under Rule 16b-3 and the settlement of the RSUs in shares is subject to shareholder approval of the 2021 LTIP; provided that if such shareholder approval is not obtained, the RSUs will remain outstanding and convert into cash-settled RSUs.
F3	One-third of the RSUs vest on each of the first, second, and third anniversaries of the date of grant without any action on the part of the participant.
