Item 8.01. Other Events.
On March 4, 2026, Post Holdings, Inc. (the “Company”) announced the pricing of its previously announced senior notes offering. The Company priced $600.0 million in aggregate principal amount of 6.250% senior notes due 2034 (the “Notes”) at a price of 100.75% of the principal amount, plus accrued interest from October 15, 2025. The $600.0 million in aggregate principal amount of the Notes represented an increase from the original size of $500.0 million. The Notes offering is expected to close on March 13, 2026, subject to customary closing conditions.
The Notes will be unsecured, senior obligations of the Company and will be guaranteed by the Company’s existing and subsequently acquired or organized domestic subsidiaries (other than immaterial subsidiaries, certain excluded subsidiaries and subsidiaries the Company designates as unrestricted subsidiaries). The Company intends to use the net proceeds from the Notes offering to pay the costs, fees and expenses associated with the Notes offering, to fund the repayment of the outstanding balance of its revolving credit facility as of December 31, 2025 and, to the extent there are any remaining net proceeds, for general corporate purposes, which could include, among other things, retirement or repayment of existing debt, share repurchases, acquisitions, capital expenditures and working capital.
The Notes and the related subsidiary guarantees were offered (1) in the United States to persons reasonably believed to be qualified institutional buyers in an offering exempt from registration pursuant to Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”), and (2) to non-U.S. persons outside of the United States in compliance with Regulation S under the Securities Act.
A copy of the press release issued in connection with the pricing of the Notes offering is attached hereto as Exhibit 99.1 and is incorporated herein by reference.
