Routine Rule 144 filing for 10,000 POST shares from equity awards.

An affiliated holder of Post Holdings, Inc. has filed a Rule 144 notice to sell 10,000 common shares on the NYSE through Charles Schwab & Co., Inc., with an aggregate market value of $1,002,109.00. The filing lists total shares of this class outstanding as 52,154,798, providing context for the size of the planned sale.

The securities were acquired on 10/22/2025 via a performance award lapse classified as equity compensation from Post Holdings, Inc. This indicates the shares stem from compensation rather than an open-market purchase. The form includes the standard representation that the seller is not aware of any material adverse, nonpublic information about the company’s operations.

As a Rule 144 notice, this primarily documents a potential secondary market sale by an existing holder and does not itself change Post’s capital structure, since the shares are already outstanding. Actual market impact, if any, would depend on trading volumes and execution on or around 11/25/2025, the approximate sale date stated.
