NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

(in millions, except per share, per unit and per principal amount information and where indicated otherwise)

NOTE 1 — BASIS OF PRESENTATION

These unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”), under the rules and regulations of the United States (the “U.S.”) Securities and Exchange Commission (the “SEC”). These unaudited condensed consolidated financial statements have been prepared on a basis substantially consistent with, and should be read in conjunction with, the audited consolidated financial statements of Post Holdings, Inc. (herein referred to as “Post,” the “Company,” “us,” “our” or “we,” and unless otherwise stated or context otherwise indicates, all such references herein mean Post Holdings, Inc. and its subsidiaries), which are included in the Company’s Annual Report on Form 10-K for the fiscal year ended September 30, 2023, filed with the SEC on November 17, 2023.

These unaudited condensed consolidated financial statements include all adjustments (consisting of normal recurring adjustments and accruals) that management considers necessary for a fair statement of the Company’s results of operations, comprehensive income, financial condition, cash flows and shareholders’ equity for the interim periods presented. Interim results are not necessarily indicative of the results for any other interim period or for the entire fiscal year. Certain reclassifications have been made to previously reported financial information to conform to the current period presentation.

NOTE 2 — RECENTLY ISSUED ACCOUNTING STANDARDS

The Company has considered all new accounting pronouncements and has concluded there are no new pronouncements (other than the ones described below) that had or will have a material impact on the Company’s results of operations, comprehensive income, financial position, cash flows, shareholders’ equity or related disclosures based on current information.

In December 2023, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures.” This ASU is effective for fiscal years beginning after December 15, 2024 (i.e., the Company’s annual financial statements for the year ended September 30, 2026), with early adoption permitted. This ASU should be adopted prospectively; however, retrospective adoption is permitted. The Company is currently evaluating the impact of this standard.

In November 2023, the FASB issued ASU 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures.” This ASU is effective for fiscal years beginning after December 15, 2023 (i.e., the Company’s annual financial statements for the year ended September 30, 2025) and for interim periods within fiscal years beginning after December 15, 2024 (i.e., the Company’s interim financial statements for the three months ended December 31, 2025), with early adoption permitted. This ASU requires retrospective adoption. The Company is currently evaluating the impact of this standard.

NOTE 3 — NONCONTROLLING INTERESTS, EQUITY INTERESTS AND RELATED PARTY TRANSACTIONS

Post Holdings Partnering Corporation

In May and June 2021, the Company and Post Holdings Partnering Corporation (“PHPC”), a special purpose acquisition company, consummated the initial public offering of 34.5 units of PHPC (the “PHPC Units” and such transaction, the “PHPC IPO”), of which a wholly-owned subsidiary of the Company (“PHPC Sponsor”) purchased 4.0 PHPC Units. Each PHPC Unit consisted of one share of Series A common stock of PHPC (“PHPC Series A Common Stock”) and one-third of one redeemable warrant to purchase one share of PHPC Series A Common Stock at an exercise price of $11.50 per share (the “PHPC Warrants”). The PHPC Units were sold at a price of $10.00 per PHPC Unit, generating gross proceeds to PHPC of $345.0. Under the terms of the PHPC IPO, PHPC was required to consummate a partnering transaction by May 28, 2023, which could have been extended to August 28, 2023 in certain circumstances (the “Combination Period”).

Substantially concurrently with the closing of the PHPC IPO, PHPC completed the private sale of 1.1 units of PHPC (the “PHPC Private Placement Units”), at a purchase price of $10.00 per PHPC Private Placement Unit, to PHPC Sponsor, generating proceeds to PHPC of $10.9 (the “PHPC Private Placement”). Each PHPC Private Placement Unit consisted of one share of PHPC Series A Common Stock and one-third of one redeemable warrant of PHPC to purchase one share of PHPC Series A Common Stock at an exercise price of $11.50 per share (the “PHPC Private Placement Warrants”).

In addition, the Company, through PHPC Sponsor’s ownership of 8.6 shares of Series F common stock of PHPC (the “PHPC Series F Common Stock”), had certain governance rights in PHPC relating to the election of PHPC directors and voting rights on amendments to PHPC’s amended and restated certificate of incorporation.

6

PHPC Sponsor was the primary beneficiary of PHPC as it had, through its equity interest, the right to receive benefits or the obligation to absorb losses from PHPC, as well as the power to direct a majority of the activities that significantly impacted PHPC’s economic performance, including partnering transaction target identification. As such, PHPC was fully consolidated into the Company’s financial statements until the time of its dissolution, as discussed below.

Proceeds of $345.0 were deposited in a trust account established for the benefit of PHPC’s public stockholders, which consisted of certain proceeds from the PHPC IPO and certain proceeds from the PHPC Private Placement, net of underwriters’ discounts and commissions and other costs and expenses.

The public stockholders’ ownership of PHPC equity represented a noncontrolling interest (“NCI”) to the Company, which was classified outside of permanent shareholders’ equity as the PHPC Series A Common Stock was redeemable at the option of the public stockholders in certain circumstances. The carrying amount of the redeemable NCI was equal to the greater of (i) the initial carrying amount, increased or decreased for the redeemable NCI’s share of PHPC’s net earnings or loss, other comprehensive income or loss (“OCI”) and distributions or (ii) the redemption value. The redemption value represented the amount the public stockholders of PHPC Series A Common Stock would be entitled in certain circumstances to redeem their shares of PHPC Series A Common Stock for, which was a pro-rata portion of the amount in the trust account at $10.00 per share of PHPC Series A Common Stock held, plus any pro-rata interest earned on the funds held in the trust account (which interest was net of taxes payable, and less up to $0.1 of interest to pay dissolution expenses). Remeasurements to the redemption value of the redeemable NCI were recognized as a deemed dividend and recorded to retained earnings on the balance sheet prior to the PHPC Redemption (as defined below).

In connection with the PHPC IPO, PHPC incurred offering costs of $17.9, of which $10.7 were deferred underwriting commissions that would have become payable to the underwriters solely in the event that PHPC completed a partnering transaction.

Prior to the PHPC Redemption, the Company beneficially owned 31.0% of the equity of PHPC and the net earnings and net assets of PHPC were consolidated within the Company’s financial statements. The remaining 69.0% of the consolidated net earnings and net assets of PHPC, which represented the percentage of economic interest in PHPC held by the public stockholders of PHPC through their ownership of PHPC equity, were allocated to redeemable NCI. All transactions between PHPC and PHPC Sponsor, as well as related financial statement impacts, eliminated in consolidation.

On May 11, 2023, PHPC announced that it would not complete a partnering transaction within the Combination Period and that the entity would liquidate and dissolve in accordance with the terms of its amended and restated certificate of incorporation. Subsequent to the decision to liquidate and dissolve, PHPC completed certain winding-up activities, which included writing-off the deferred underwriting commissions as the underwriters agreed to waive their rights to these amounts should a partnering transaction not occur. The Company recorded a $10.7 gain in connection with this write-off, which was recorded in “Other income, net” on the Condensed Consolidated Statements of Operations during both the three and nine months ended June 30, 2023.

On May 28, 2023, the PHPC Warrants and the PHPC Private Placement Warrants expired worthless, as PHPC had not completed a partnering transaction before the expiration of the Combination Period.

On May 30, 2023, PHPC redeemed all of the outstanding public shares of PHPC Series A Common Stock (the “PHPC Redemption”). Each share of PHPC Series A Common Stock was redeemed for approximately $10.24 per share, representing the per share price equal to the aggregate amount then on deposit in the trust account, including interest earned on the trust account not previously released to pay taxes or dissolution expenses, divided by the number of then outstanding shares of PHPC Series A Common Stock. In connection with the PHPC Redemption, during the three and nine months ended June 30, 2023:

•$353.4 of funds held in the trust account immediately prior to the PHPC Redemption were distributed to redeem all of the outstanding shares of PHPC Series A Common Stock. The Company received $40.9 from the PHPC Redemption related to its ownership of 4.0 shares of PHPC Series A Common Stock; and

•redeemable NCI of $312.5 immediately prior to the PHPC Redemption was reduced to zero.

Subsequent to the PHPC Redemption, PHPC delisted from the New York Stock Exchange and dissolved in June 2023, and all classes of shares of PHPC equity were cancelled, including the PHPC Private Placement Units and the shares of the PHPC Series F Common Stock, which were surrendered by PHPC Sponsor for no consideration. PHPC Sponsor subsequently dissolved in August 2023.

8th Avenue

The Company has a 60.5% common equity interest in 8th Avenue Food & Provisions, Inc. (“8th Avenue”) that is accounted for using the equity method. In determining the accounting treatment of the common equity interest, management concluded that 8th Avenue was not a variable interest entity as defined by Accounting Standards Codification (“ASC”) Topic 810, “Consolidation,” and as such, 8th Avenue was evaluated under the voting interest model. Based on the terms of 8th Avenue’s governing documents, management determined that the Company does not have a controlling voting interest in 8th Avenue due to substantive participating rights held by third parties associated with the governance of 8th Avenue. However, Post does retain significant influence, and therefore, the use of the equity method of accounting is required.

During fiscal 2022, 8th Avenue’s equity method loss attributable to Post exceeded the Company’s remaining investment in 8th Avenue. As such, in accordance with ASC Topic 323, “Investments—Equity Method and Joint Ventures,” the Company discontinued applying the equity method to the investment after reducing the balance of the investment to zero. The Company’s investment in 8th Avenue was zero at both June 30, 2024 and September 30, 2023, and the Company did not recognize an equity method gain (loss) attributable to 8th Avenue for the three or nine months ended June 30, 2024 or 2023.

During the three and nine months ended June 30, 2024, the Company had net sales to 8th Avenue of $1.5 and $5.3, respectively, and purchases from and royalties paid to 8th Avenue of $21.5 and $61.1, respectively.

NOTE 4 — BUSINESS COMBINATIONS

The Company uses the acquisition method of accounting for acquired businesses. Under the acquisition method, the Company’s financial statements reflect the operations of an acquired business starting from the date of acquisition. The assets acquired and liabilities assumed are recorded at their respective estimated fair values at the date of the acquisition based on Level 3 inputs. Any excess of the purchase price over the estimated fair values of the identifiable net assets acquired is recorded as goodwill. Any excess of the estimated fair values of the identifiable net assets acquired over the purchase price is recorded as a gain on bargain purchase. Goodwill represents the value the Company expects to achieve through the implementation of operational synergies, the expansion of the business into new or growing segments of the industry and the addition of new employees.

Fiscal 2024

On December 1, 2023, the Company completed its acquisition of substantially all of the assets of Perfection Pet Foods, LLC (“Perfection”) for $235.0, subject to working capital adjustments and other adjustments, resulting in a payment at closing of $238.8. Perfection is a manufacturer and packager of private label and co-manufactured pet food and baked treat products and is reported in the Post Consumer Brands segment. The acquisition was completed using cash on hand, including borrowings under the Revolving Credit Facility (as defined in Note 13). During the third quarter of fiscal 2024, the Company reached a final settlement of net working capital, resulting in an amount received by the Company of $4.6.

Based upon the preliminary purchase price allocation, the Company recorded $81.0 of customer relationships, which is being amortized over a weighted-average useful life of 16 years. Net sales and operating profit included in the Condensed Consolidated Statements of Operations attributable to Perfection were $62.1 and $4.2, respectively, for the three months ended June 30, 2024 and $146.7 and $9.1, respectively, for the nine months ended June 30, 2024.

Preliminary values of Perfection are measured as of the date of the acquisition, are not yet finalized pending the final purchase price allocation and are subject to change. The goodwill generated by the Company’s Perfection acquisition is expected to be deductible for U.S. income tax purposes.

Also on December 1, 2023, the Company completed its acquisition of Deeside Cereals I Ltd (“Deeside”) for £11.3 (approximately $14.3). The acquisition was completed using cash on hand. Deeside is a producer of private label cereals in the United Kingdom (the “U.K.”) and is reported in the Weetabix segment. Based upon the preliminary purchase price allocation, the Company identified and recorded $20.5 of net assets, which exceeded the purchase price paid for Deeside. As a result, the Company recorded an initial gain on bargain purchase of $6.2 during the first quarter of fiscal 2024. During the third quarter of fiscal 2024, the Company recorded measurement period adjustments related to Deeside’s defined benefit pension plan and deferred taxes, which reduced the acquired Deeside net assets by $0.4. As a result, the Company recorded an adjustment to (gain) on bargain purchase of $0.4 and $(5.8) during the three and nine months ended June 30, 2024, respectively, which was included in “Other operating expense (income), net” in the Condensed Consolidated Statements of Operations. Net sales and operating loss included in the Condensed Consolidated Statements of Operations attributable to Deeside were $7.5 and $0.3, respectively, for the three months ended June 30, 2024 and $17.0 and $1.2, respectively, for the nine months ended June 30, 2024. Preliminary values of Deeside are measured as of the date of the acquisition, are not yet finalized pending the final purchase price allocation and are subject to change.

Acquisition-related costs for fiscal 2024 acquisitions were immaterial during the three and nine months ended June 30, 2024.

Fiscal 2023

On April 28, 2023, the Company completed its acquisition of a portion of The J. M. Smucker Company’s (“Smucker”) pet food business, including brands such as Rachael Ray Nutrish, Nature’s Recipe, 9Lives, Kibbles ’n Bits and Gravy Train, private label pet food assets and certain manufacturing and distribution facilities (collectively, “Pet Food”), facilitating the Company’s entry into the pet food category. The purchase price of the Pet Food acquisition was $1,207.5 which included (i) $700.0 in cash, subject to inventory adjustments, resulting in a payment at closing of $715.5, (ii) 5.4 shares of Post common stock, or $492.3, and (iii) immaterial working capital adjustments. The cash payment was made using cash on hand, including proceeds from the Fourth Incremental Term Loan (as defined in Note 13). Pet Food is reported in the Post Consumer Brands segment.

In connection with the Pet Food acquisition, the Company and Smucker entered into a transition services agreement (the “TSA”) pursuant to which Smucker provides certain Pet Food support services to Post for a transition period of 18 months (or up to 24 months at Post’s election) following the close of the acquisition based on the terms set forth in the TSA. Pet Food support services include, but are not limited to, certain sales, marketing, finance, information technology, procurement and supply chain services. TSA fees were $3.5 and $13.0 during the three and nine months ended June 30, 2024, respectively, and $4.0 during both the three and nine months ended June 30, 2023. TSA fees were recorded within “Selling, general and administrative expenses” in the Condensed Consolidated Statements of Operations. In accordance with the terms of the TSA, Smucker collects sales receivables from and remits payments to customers and vendors, respectively, in accordance with Smucker’s existing contractual terms. Pet Food receivables and payables are settled between Post and Smucker monthly on a net basis per the terms of the TSA. As of June 30, 2024 and September 30, 2023, the Company had recorded a net receivable due from Smucker related to the TSA of $39.1 and $35.5, respectively, which was recorded within “Receivables, net” on the Condensed Consolidated Balance Sheets.

Restructuring (adjustments) charges of $(1.1) and $6.6 were included in “Selling, general and administrative expenses” in the Condensed Consolidated Statements of Operations during the three and nine months ended June 30, 2024, respectively. No restructuring charges were incurred during the three or nine months ended June 30, 2023.

NOTE 6 — EARNINGS PER SHARE

Basic earnings per share is based on the average number of shares of common stock outstanding during the period. Diluted earnings per share is based on the average number of shares used for the basic earnings per share calculation, adjusted for the dilutive effect of stock options, stock appreciation rights and restricted stock units using the “treasury stock” method and convertible senior notes using the “if converted” method.

Remeasurements to the redemption value of the redeemable NCI prior to the PHPC Redemption were recognized as a deemed dividend (see Note 3). The Company made an election to treat the portion of the deemed dividend that exceeded fair value as an adjustment to income available to common shareholders for basic and diluted earnings per share. In addition, dilutive net earnings was adjusted for interest expense, net of tax, related to the Company’s convertible senior notes.

NOTE 11 — DERIVATIVE FINANCIAL INSTRUMENTS

In the ordinary course of business, the Company is exposed to commodity price risks relating to the purchases of raw materials and supplies, interest rate risks and foreign currency exchange rate risks. The Company utilizes derivative financial instruments, including (but not limited to) futures contracts, option contracts, forward contracts and swaps, to manage certain of these exposures by hedging when it is practical to do so. The Company does not hold or issue financial instruments for speculative or trading purposes.

Cash flows associated with all derivatives are reported as cash flows from operating activities in the Condensed Consolidated Statements of Cash Flows, unless the derivative contains an other-than-insignificant financing element, in which case its cash flows are reported as cash flows from financing activities.

At June 30, 2024, the Company’s derivative instruments, none of which were designated as hedging instruments under ASC Topic 815, “Derivatives and Hedging,” consisted of:

•commodity and energy futures, swaps and option contracts which relate to inputs that generally will be utilized within the next two years;

•foreign currency forward contracts (the “FX contracts”) maturing in the next 12 months that have the effect of hedging currency fluctuations between the Euro and the Pound Sterling; and

•pay-fixed, receive-variable interest rate swaps maturing in June 2033 that require monthly settlements and have the effect of hedging interest payments on debt expected to be issued but not yet priced.

During the nine months ended June 30, 2024, the Company received cash proceeds of $5.2 in connection with the termination of its interest rate swap contracts with a $400.0 notional value.

13

During the nine months ended June 30, 2023, the Company paid $55.1 in connection with the termination of $849.3 notional value of its rate-lock swap contracts, of which $43.5 related to the termination of rate-lock swap contracts that contained other-than-insignificant financing elements and were reported as cash flows from financing activities in the Condensed Consolidated Statements of Cash Flows. The Company also paid $2.1 in connection with the termination of $332.6 notional value of its interest rate swap option, and received cash proceeds of $6.7 in connection with the termination of its interest rate swap contract with a $200.0 notional value.

The following table presents the notional amounts of derivative instruments held.

NOTE 12 — FAIR VALUE MEASUREMENTS

The following table presents the Company’s assets and liabilities measured at fair value on a recurring basis and the basis for that measurement according to the levels in the fair value hierarchy in ASC Topic 820, “Fair Value Measurement.”

	June 30, 2024						September 30, 2023
	Total		Level 1		Level 2		Total		Level 1		Level 2
Assets:
Deferred compensation investments	$	15.5	$	15.5	$	—	$	13.0	$	13.0	$	—
Derivative assets	11.1		—		11.1		25.6		—		25.6
	$	26.6	$	15.5	$	11.1	$	38.6	$	13.0	$	25.6

	$	55.1	$	—	$	55.1	$	52.9	$	—	$	52.9

Deferred Compensation

The deferred compensation investments are primarily invested in mutual funds, and their fair value is measured using the market approach. These investments are in the same funds, or funds that employ a similar investment strategy, and are purchased in substantially the same amounts, as the participants’ selected notional investment options (excluding Post common stock equivalents), which represent the underlying liabilities to participants in the Company’s deferred compensation plans. Deferred compensation liabilities are recorded at amounts due to participants in cash, based on the fair value of participants’ selected notional investment options (excluding certain Post common stock equivalents to be distributed in shares) using the market approach.

Derivatives

The Company utilizes the income approach to measure fair value for its commodity and energy derivatives. The income approach uses pricing models that rely on market observable inputs such as yield curves and forward prices. FX contracts are valued using the spot rate less the forward rate multiplied by the notional amount. The Company’s calculation of the fair value of interest rate swaps is derived from a discounted cash flow analysis based on the terms of the contract and the interest rate curve. Refer to Note 11 for the classification of changes in fair value of derivative assets and liabilities measured at fair value on a recurring basis within the Condensed Consolidated Statements of Operations.

Equity Securities and Other Fair Value Measurements

The Company uses the market approach to measure the fair value of its equity securities, which were immaterial as of both June 30, 2024 and September 30, 2023. The Company’s financial assets and liabilities also include cash and cash equivalents, receivables and accounts payable for which the carrying value approximates fair value due to their short maturities (less than 12 months). The Company does not record its current portion of long-term debt and long-term debt at fair value on the Condensed Consolidated Balance Sheets. The fair values of any outstanding borrowings under the municipal bond and the Revolving Credit Facility (as defined in Note 13) as of June 30, 2024 and September 30, 2023 approximated their carrying values. Based on current market rates, the fair value (Level 2) of the Company’s debt, excluding any outstanding borrowings under the municipal bond and the Revolving Credit Facility, was $5,904.7 and $5,491.5 as of June 30, 2024 and September 30, 2023, respectively, which included $632.8 and $572.6 related to the Company’s convertible senior notes, respectively.

Certain assets and liabilities, including property, goodwill and other intangible assets, are measured at fair value on a non-recurring basis using Level 3 inputs.

6.25% Senior Notes

On February 20, 2024, the Company issued $1,000.0 principal value of 6.25% senior secured notes (the “6.25% senior notes”) maturing in February 2032. The 6.25% senior notes were issued at par, and the Company received $986.7 after incurring underwriting fees and other fees and expenses of $13.3, which were deferred and are being amortized to interest expense over the term of the 6.25% senior notes. Interest payments on the 6.25% senior notes are due semi-annually each August 15 and February 15, and the maturity date of the 6.25% senior notes is February 15, 2032.

The 6.25% senior notes and the related guarantees are secured by first-priority security interests, subject to permitted liens, in collateral that generally includes most of the Company’s and the subsidiary guarantors’ property except for real property and certain other excluded assets. The assets that secure the 6.25% senior notes also secure (and will continue to secure) the Credit Agreement (as defined below) on a pari passu basis.

The 6.25% senior notes are fully and unconditionally guaranteed, jointly and severally, on a senior secured basis by each of the Company’s existing and subsequently acquired or organized wholly-owned domestic subsidiaries that guarantee the Credit Agreement or certain of the Company’s other indebtedness, other than immaterial subsidiaries, certain excluded subsidiaries and subsidiaries the Company designates as unrestricted subsidiaries, which such unrestricted subsidiaries include 8th Avenue and its subsidiaries. These guarantees are subject to release in certain circumstances.

With a portion of the net proceeds received from the 6.25% senior notes issuance, borrowings under the New Revolving Credit Facility (as defined below) and cash on hand, the Company repaid the outstanding principal balance of the Fourth Incremental Term Loan (as defined below) and all accrued, unpaid interest thereon, redeemed the remainder of the outstanding 5.75% senior notes maturing in March 2027 and all accrued, unpaid interest to the redemption date and repaid the outstanding borrowings under the Old Revolving Credit Facility (as defined below) and all accrued, unpaid interest thereon. For additional information, see the “Credit Agreement,” “Fourth Incremental Term Loan” and “Repayments of Debt” sections below.

Convertible Senior Notes

On August 12, 2022, the Company issued $575.0 principal value of 2.50% convertible senior notes maturing in August 2027. The initial conversion rate of the 2.50% convertible senior notes is 9.4248 shares of the Company’s common stock per one thousand dollars principal amount of the 2.50% convertible senior notes, which represents an initial conversion price of approximately $106.10 per share of common stock. The conversion rate, and thus the conversion price, may be adjusted under certain circumstances as described in the indenture governing the 2.50% convertible senior notes (the “Convertible Notes Indenture”). The Company may settle conversions by paying or delivering, as applicable, cash, shares of its common stock or a combination of cash and shares of its common stock, at the Company’s election. If a “make-whole fundamental change” (as

16

defined in the Convertible Notes Indenture) occurs, then the Company must in certain circumstances increase the conversion rate for a specified period of time.

The 2.50% convertible senior notes may be converted at the holder’s option up to the second scheduled trading day immediately before the maturity date of August 15, 2027 under the following circumstances:

•during any calendar quarter (and only during such calendar quarter) if the last reported sale price per share of the Company’s common stock exceeds 130% of the conversion price for each of at least 20 trading days, whether or not consecutive, during the 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter;

•during the five consecutive business days immediately after any 10 consecutive trading day period (such 10 consecutive trading day period, the “Measurement Period”) in which the trading price per one thousand dollars principal amount of the 2.50% convertible senior notes for each trading day of the Measurement Period was less than 98% of the product of the last reported sale price per share of the Company’s common stock on such trading day and the conversion rate on such trading day;

•upon the occurrence of certain corporate events or distributions on the Company’s common stock described in the Convertible Notes Indenture;

•if the Company calls the 2.50% convertible senior notes for redemption; and

•at any time from, and including, May 15, 2027 until the close of business on the second scheduled trading day immediately before the August 15, 2027 maturity date.

If a “fundamental change” (as defined in the Convertible Notes Indenture) occurs, then, except as described in the Convertible Notes Indenture, holders of the 2.50% convertible senior notes may require the Company to repurchase their 2.50% convertible senior notes at a cash repurchase price equal to the principal amount of the 2.50% convertible senior notes to be repurchased, plus accrued and unpaid interest, if any, to, but excluding, the “fundamental change repurchase date” (as defined in the Convertible Notes Indenture).

The 2.50% convertible senior notes may be redeemed, in whole or in part (subject to the partial redemption limitation described in the Convertible Notes Indenture), at the Company’s option at any time, and from time to time, on or after August 20, 2025 and on or before the 35th scheduled trading day immediately before August 15, 2027, at a cash redemption price equal to the principal amount of the 2.50% convertible senior notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the redemption date, only if the last reported sale price per share of the Company’s common stock exceeds 130% of the conversion price on (i) each of at least 20 trading days, whether or not consecutive, during the 30 consecutive trading days ending on, and including, the trading day immediately before the date the Company sends the related redemption notice, and (ii) the trading day immediately before the date the Company sends such notice.

As of both June 30, 2024 and September 30, 2023, none of the conditions permitting holders to convert their 2.50% convertible senior notes had been satisfied, and no shares of the Company’s common stock had been issued in connection with any conversions of the 2.50% convertible senior notes.

The 2.50% convertible senior notes had no embedded features that required separate bifurcation under ASC Topic 815 as of June 30, 2024 or September 30, 2023. As such, the 2.50% convertible senior notes were recorded at the principal amount, net of unamortized issuance costs, on the Condensed Consolidated Balance Sheets as of both June 30, 2024 and September 30, 2023.

Credit Agreement

On March 18, 2020, the Company entered into a second amended and restated credit agreement (as amended, including by Joinder Agreement No. 1, Joinder Agreement No. 2, the Third Joinder Agreement (as defined below), the Fourth Joinder Agreement (as defined below) and the Third Amendment (as defined below), as amended, restated or amended and restated, the “Credit Agreement”). Prior to the effective date of the Third Amendment, the Credit Agreement provided for a revolving credit facility in an aggregate principal amount of $750.0 (the “Old Revolving Credit Facility”), with the commitments thereunder to be made available to the Company in U.S. Dollars, Canadian Dollars, Euros and Pounds Sterling. Letters of credit are available under the Credit Agreement in an aggregate amount of up to $75.0.

On February 20, 2024, the Company entered into a third amendment to the Credit Agreement (the “Third Amendment”) by and among the Company, as borrower, certain of the Company’s subsidiaries, as guarantors, Barclays Bank PLC (“Barclays”), as administrative agent under the Credit Agreement prior to the effective date of the Third Amendment, JPMorgan Chase Bank, N.A. (“JPMorgan Chase”), as administrative agent under the Credit Agreement from and after the effective date of the Third Amendment, the institutions constituting the 2024 Revolving Credit Lenders, the L/C Issuers and the Swing Line Lender (as

17

each such term is defined in the Third Amendment). The Company incurred $6.6 of financing fees in connection with the Third Amendment, which were deferred and are being amortized to interest expense over the remaining term of the Credit Agreement.

The Third Amendment to the Credit Agreement (i) replaced the Old Revolving Credit Facility with a new revolving credit facility in an aggregate principal amount of $1,000.0 (the “New Revolving Credit Facility”), (ii) extended the maturity date of the New Revolving Credit Facility to February 20, 2029, provided that if on October 16, 2027 the Company’s 5.625% senior notes maturing in January 2028 have not been redeemed in full in cash or refinanced and replaced in full with notes and/or loans maturing at least 91 days after February 20, 2029, then the maturity date of the New Revolving Credit Facility will be October 16, 2027 and (iii) modified certain other terms, conditions and provisions of the Credit Agreement, including transferring the administrative agent role from Barclays to JPMorgan Chase. The term “Revolving Credit Facility” used herein generally refers to the Old Revolving Credit Facility prior to the Third Amendment and the New Revolving Credit Facility subsequent to the Third Amendment.

Borrowings in U.S. Dollars under the New Revolving Credit Facility bear interest, at the option of the Company, at an annual rate equal to either (a) the adjusted term SOFR rate (as defined in the Credit Agreement) or (b) the base rate determined by reference to the highest of (i) the prime rate, (ii) the NYFRB Rate (as defined in the Credit Agreement) plus 0.50% per annum and (iii) the one-month adjusted term SOFR rate plus 1.00% per annum, in each case plus an applicable margin, which is determined by reference to the secured net leverage ratio (as defined in the Credit Agreement), with the applicable margin for adjusted term SOFR rate loans and base rate loans being (i) 2.00% and 1.00%, respectively, if the secured net leverage ratio is greater than or equal to 3.00:1.00, (ii) 1.75% and 0.75%, respectively, if the secured net leverage ratio is less than 3.00:1.00 and greater than or equal to 1.50:1.00 or (iii) 1.50% and 0.50%, respectively, if the secured net leverage ratio is less than 1.50:1.00. Commitment fees on the daily unused amount of commitments under the Revolving Credit Facility accrue at a rate of 0.375% if the Company’s secured net leverage ratio is greater than or equal to 3.00:1.00, and accrue at a rate of 0.25% if the Company’s secured net leverage ratio is less than 3.00:1.00.

During the nine months ended June 30, 2024, the Company borrowed $645.0 and repaid $345.0 under the Revolving Credit Facility. There were no borrowings or repayments under the Revolving Credit Facility during the nine months ended June 30, 2023. As of June 30, 2024, the Revolving Credit Facility had outstanding borrowings of $300.0, outstanding letters of credit of $20.0 and an available borrowing capacity of $680.0. As of September 30, 2023, the Revolving Credit Facility had no outstanding borrowings, outstanding letters of credit of $19.7 and an available borrowing capacity of $730.3. As of June 30, 2024, the interest rate on the outstanding borrowings under the Revolving Credit Facility was 6.93%.

The Credit Agreement provides for potential incremental revolving and term facilities at the request of the Company and at the discretion of the lenders or other persons providing such incremental facilities, in each case on terms to be determined, and also permits the Company to incur other secured or unsecured debt, in all cases subject to conditions and limitations specified in the Credit Agreement.

The Credit Agreement provides for customary events of default, including material breach of representations and warranties, failure to make required payments, failure to comply with certain agreements or covenants, failure to pay or default under certain other indebtedness in excess of $125.0, certain events of bankruptcy and insolvency, inability to pay debts, the occurrence of one or more unstayed or undischarged judgments in excess of $125.0, attachments issued against all or any material part of the Company’s property, certain events under the Employee Retirement Income Security Act of 1974, a change of control (as defined in the Credit Agreement), the invalidity of any loan document and the failure of the collateral documents to create a valid and perfected first priority lien (subject to certain permitted liens). Upon the occurrence and during the continuance of an event of default, the maturity of the loans under the Credit Agreement may accelerate and the agent and lenders under the Credit Agreement may exercise other rights and remedies available at law or under the loan documents, including with respect to the collateral and guarantees of the Company’s obligations under the Credit Agreement.

Third Incremental Term Loan

On November 18, 2022, the Company entered into Joinder Agreement No. 3 (the “Third Joinder Agreement”) by and among the Company, as borrower, certain of the Company’s subsidiaries, as guarantors, J.P. Morgan Securities LLC (“J.P. Morgan”), as lender, Barclays, as administrative agent, and JPMorgan Chase, as sub-agent to the administrative agent. The Third Joinder Agreement provided for an incremental term loan (the “Third Incremental Term Loan”) of $130.0 under the Company’s Credit Agreement, which the Company borrowed in full on November 18, 2022.

On November 21, 2022, the Company and J.P. Morgan entered into an exchange agreement pursuant to which the Company transferred the remaining shares of BellRing common stock it held from its previous transactions related to the distribution of a portion of its interest in BellRing, which occurred in fiscal 2022, to J.P. Morgan to repay $99.9 in aggregate principal amount of the Third Incremental Term Loan (such exchange, the “Fiscal 2023 Debt-for-Equity Exchange”). Following the completion of the Fiscal 2023 Debt-for-Equity Exchange, the Company no longer held shares of BellRing

18

common stock. On November 25, 2022, the Company repaid the remaining principal balance of $30.1 of the Third Incremental Term Loan using cash on hand. For additional information, see “Repayments of Debt” below.

Fourth Incremental Term Loan

On April 26, 2023, the Company entered into Joinder Agreement No. 4 (the “Fourth Joinder Agreement”) by and among the Company, as borrower, certain of the Company’s subsidiaries, as guarantors, the institutions party to the Fourth Joinder Agreement as lenders and Barclays, as the administrative agent. The Fourth Joinder Agreement provided for an incremental term loan (the “Fourth Incremental Term Loan”) of $400.0 under the Credit Agreement, which the Company borrowed in full on April 26, 2023.

On February 20, 2024, the Company repaid the outstanding principal balance of the Fourth Incremental Term Loan and all accrued, unpaid interest thereon using a portion of the net proceeds from the 6.25% senior notes issuance. For additional information, see “Repayments of Debt” below.

Interest on the Fourth Incremental Term Loan accrued, at the Company’s option, at the base rate (as defined in the Credit Agreement) plus 1.25% per annum or the adjusted term SOFR rate plus 2.25% per annum. Interest was payable quarterly for loans bearing interest based upon the base rate and either monthly or every three months (depending on the applicable interest period) for loans bearing interest based upon the adjusted term SOFR rate. As of September 30, 2023, the interest rate on the Fourth Incremental Term Loan was 7.67%.

Municipal Bond

In connection with the construction of a filtration system at the Company’s potato plant in Chaska, Minnesota, the Company incurred debt that guarantees the repayment of certain industrial revenue bonds used to finance the construction of the project. Principal payments are due annually on March 1, and interest payments are due semi-annually each March 1 and September 1. The debt matures on March 1, 2028.

Debt Covenants

Under the terms of the Credit Agreement, the Company is required to comply with a financial covenant consisting of a secured net leverage ratio not to exceed 4.25:1.00 measured as of the last day of any fiscal quarter if, as of the last day of such fiscal quarter, the aggregate outstanding amount of all revolving credit loans, swing line loans and letter of credit obligations (subject to certain exceptions specified in the Credit Agreement) exceeds 30% of the Company’s revolving credit commitments. As of June 30, 2024, the Company was in compliance with this financial covenant.

The Credit Agreement provides for incremental revolving and term loan facilities, and also permits other secured or unsecured debt, if, among other conditions, certain financial ratios are met, as defined and specified in the Credit Agreement.

NOTE 14 — COMMITMENTS AND CONTINGENCIES

Legal Proceedings

The Company is subject to various legal proceedings and actions arising in the normal course of business. In the opinion of management, based upon the information presently known, the ultimate liability, if any, arising from such pending legal proceedings, as well as from asserted legal claims and known potential legal claims which are likely to be asserted, taking into account established accruals for estimated liabilities (if any), are not expected to be material individually or in the aggregate to

20

the consolidated financial condition, results of operations or cash flows of the Company. In addition, although it is difficult to estimate the potential financial impact of actions regarding expenditures for compliance with regulatory matters, in the opinion of management, based upon the information currently available, the ultimate liability arising from such compliance matters is not expected to be material to the consolidated financial condition, results of operations or cash flows of the Company.

NOTE 15 — PENSION AND OTHER POSTRETIREMENT BENEFITS

The Company maintains qualified defined benefit plans in the U.S., the U.K. and Canada for certain employees primarily within its Post Consumer Brands and Weetabix segments. Certain of the Company’s employees are eligible to participate in the Company’s postretirement benefit plans (partially subsidized retiree health and life insurance).

On February 16, 2024, the Company adopted the Post Holdings, Inc. 2024 Supplemental Executive Retirement Plan (the “SERP”), an unfunded, non-qualified defined benefit retirement plan for certain management employees of the Company, including its named executive officers, that was effective on February 19, 2024. The SERP is a supplemental program that provides a cash balance benefit to each participant. The SERP participants were credited with an opening credit, based on years of past service with the Company, and accrue ongoing benefits with a pay credit equal to a percentage of certain of the participant’s annualized compensation. The Company recorded an initial projected benefit obligation of $8.3 related to the SERP during the second quarter of fiscal 2024, which was included in “Accumulated other comprehensive loss” on the Condensed Consolidated Balance Sheets at June 30, 2024. Net periodic benefit costs related to the SERP during the three and nine months ended June 30, 2024 were immaterial.

Amounts for the Canadian plans and the SERP are included in the North America disclosures and are not disclosed separately because they do not constitute a significant portion of the combined amounts.

The following tables present the components of net periodic benefit cost (income) for the pension plans. Service cost was reported in “Cost of goods sold” and “Selling, general and administrative expenses” and all other components of net periodic benefit cost (income) were reported in “Other income, net” in the Condensed Consolidated Statements of Operations.

(b)“Purchases of treasury stock” in the Condensed Consolidated Statements of Cash Flows for the nine months ended June 30, 2024 excluded $4.0 of repurchases of common stock that were accrued in the third quarter of fiscal 2024 but did not settle until July 2024 and $1.8 of accrued excise tax that had not been paid as of June 30, 2024. “Purchases of treasury stock” in the Condensed Consolidated Statements of Cash Flows for the nine months ended June 30, 2023 excluded $8.1 of repurchases of common stock that were accrued in the third quarter of fiscal 2023 but did not settle until July 2023.

In February 2024, the Company entered into a structured share repurchase arrangement, which consisted of purchased call options with a $0 strike price per option and written call options with a $99.45 strike price per option. The Company paid $50.0 of net premiums in connection with the contracts, which were included in “Payment for share repurchase contracts” in the Condensed Consolidated Statements of Cash Flows for the nine months ended June 30, 2024. Upon settlement, the Company had the right to receive approximately 0.5 shares of Post common stock, to be settled in shares or cash, at the option of the Company. The contracts settled in May 2024, which resulted in the Company receiving cash proceeds of $50.9, which were included in “Proceeds from share repurchase contracts” in the Condensed Consolidated Statements of Cash Flows for the nine months ended June 30, 2024.

NOTE 17 — SEGMENTS

At June 30, 2024, the Company managed and reported operating results through the following four reportable segments:

•Post Consumer Brands: North American RTE cereal, pet food and peanut butter;

•Weetabix: primarily U.K. RTE cereal, muesli and protein-based shakes;

•Foodservice: primarily egg and potato products; and

•Refrigerated Retail: primarily side dish, egg, cheese and sausage products.

Due to the level of integration between the Foodservice and Refrigerated Retail segments, it is impracticable to present total assets separately for each segment. An allocation has been made between the two segments for depreciation based on inventory costing.

Amounts reported for Corporate in the table below include any amounts attributable to PHPC prior to the PHPC Redemption in the third quarter of fiscal 2023 (see Note 3).

Management evaluates each segment’s performance based on its segment profit, which for all segments is its earnings/loss before income taxes and equity method earnings/loss before impairment of property, goodwill and other intangible assets, facility closure related costs, restructuring expenses, gain/loss on assets and liabilities held for sale, gain/loss on sale of

22

businesses and facilities, gain on/adjustment to bargain purchase, interest expense and other unallocated corporate income and expenses.

The following tables present information about the Company’s reportable segments. In addition, the tables present net sales by product.

ITEM 2.     MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS.

The following discussion summarizes the significant factors affecting the consolidated operating results, financial condition, liquidity and capital resources of Post Holdings, Inc. This discussion should be read in conjunction with our unaudited condensed consolidated financial statements and notes thereto included herein, our audited consolidated financial statements and notes thereto found in our Annual Report on Form 10-K for the fiscal year ended September 30, 2023 and the “Cautionary Statement on Forward-Looking Statements” section included below. The terms “our,” “we,” “us,” “Company” and “Post” as used herein refer to Post Holdings, Inc. and its subsidiaries.

OVERVIEW

We are a consumer packaged goods holding company operating in four reportable segments: Post Consumer Brands, Weetabix, Foodservice and Refrigerated Retail. Our products are sold through a variety of channels, including grocery, club and drug stores, mass merchandisers, foodservice, food ingredient and eCommerce.

At June 30, 2024, our reportable segments were as follows:

•Post Consumer Brands: North American ready-to-eat (“RTE”) cereal, pet food and peanut butter;

•Weetabix: primarily United Kingdom (the “U.K.”) RTE cereal, muesli and protein-based shakes;

•Foodservice: primarily egg and potato products; and

•Refrigerated Retail: primarily side dish, egg, cheese and sausage products.

Transactions

Post Holdings Partnering Corporation

In May and June 2021, we and Post Holdings Partnering Corporation (“PHPC”), a special purpose acquisition company, consummated the initial public offering of 34.5 million units of PHPC (the “PHPC Units” and such transaction, the “PHPC IPO”), of which our wholly-owned subsidiary (“PHPC Sponsor”) purchased 4.0 million PHPC Units. Each PHPC Unit consisted of one share of Series A common stock of PHPC (“PHPC Series A Common Stock”) and one-third of one redeemable warrant to purchase one share of PHPC Series A Common Stock at an exercise price of $11.50 per share (the “PHPC Warrants”). The PHPC Units were sold at a price of $10.00 per PHPC Unit, generating gross proceeds to PHPC of $345.0 million. Under the terms of the PHPC IPO, PHPC was required to consummate a partnering transaction by May 28, 2023, which could have been extended to August 28, 2023 in certain circumstances (the “Combination Period”).

Substantially concurrently with the closing of the PHPC IPO, PHPC completed the private sale of 1.1 million units of PHPC (the “PHPC Private Placement Units”), at a purchase price of $10.00 per PHPC Private Placement Unit, to PHPC Sponsor, generating proceeds to PHPC of $10.9 million (the “PHPC Private Placement”). Each PHPC Private Placement Unit consisted of one share of PHPC Series A Common Stock and one-third of one redeemable warrant of PHPC to purchase one share of PHPC Series A Common Stock at an exercise price of $11.50 per share (the “PHPC Private Placement Warrants”).

In addition, we, through PHPC Sponsor’s ownership of 8.6 million shares of Series F common stock of PHPC (the “PHPC Series F Common Stock”), had certain governance rights in PHPC relating to the election of PHPC directors and voting rights on amendments to PHPC’s amended and restated certificate of incorporation.

Proceeds of $345.0 million were deposited in a trust account established for the benefit of PHPC’s public stockholders, which consisted of certain proceeds from the PHPC IPO and certain proceeds from the PHPC Private Placement, net of underwriters’ discounts and commissions and other costs and expenses.

The public stockholders’ ownership of PHPC equity represented a noncontrolling interest (“NCI”) to us, which was classified outside of permanent shareholders’ equity as the PHPC Series A Common Stock was redeemable at the option of the public stockholders in certain circumstances.

On May 11, 2023, PHPC announced that it would not complete a partnering transaction within the Combination Period and that the entity would liquidate and dissolve in accordance with the terms of its amended and restated certificate of incorporation. Subsequent to the decision to liquidate and dissolve, PHPC completed certain winding-up activities, which included writing-off the deferred underwriting commissions as the underwriters agreed to waive their rights to these amounts should a partnering transaction not occur. We recorded a $10.7 million gain in connection with this write-off during the third quarter of fiscal 2023.

On May 28, 2023, the PHPC Warrants and the PHPC Private Placement Warrants expired worthless, as PHPC had not completed a partnering transaction before the expiration of the Combination Period.

25

On May 30, 2023, PHPC redeemed all of the outstanding public shares of PHPC Series A Common Stock (the “PHPC Redemption”). Each share of PHPC Series A Common Stock was redeemed for approximately $10.24 per share, representing the per share price equal to the aggregate amount then on deposit in the trust account, including interest earned on the trust account not previously released to pay taxes or dissolution expenses, divided by the number of then outstanding shares of PHPC Series A Common Stock. In connection with the PHPC Redemption, $353.4 million of funds held in the trust account immediately prior to the PHPC Redemption were distributed to redeem all of the outstanding shares of PHPC Series A Common Stock. We received $40.9 million from the PHPC Redemption related to our ownership of 4.0 million shares of PHPC Series A Common Stock.

Subsequent to the PHPC Redemption, PHPC delisted from the New York Stock Exchange and dissolved in June 2023, and all classes of shares of PHPC equity were cancelled, including the PHPC Private Placement Units and the shares of PHPC Series F Common Stock, which were surrendered by PHPC Sponsor for no consideration. PHPC Sponsor subsequently dissolved in August 2023.

Acquisitions

Fiscal 2024

On December 1, 2023, we completed our acquisition of substantially all of the assets of Perfection Pet Foods, LLC (“Perfection”), a manufacturer and packager of private label and co-manufactured pet food and baked treat products, which is reported in our Post Consumer Brands segment.

Also on December 1, 2023, we completed our acquisition of Deeside Cereals I Ltd (“Deeside”), a private label cereal manufacturer based in the U.K., which is reported in our Weetabix segment.

Fiscal 2023

On April 28, 2023, we completed our acquisition of a portion of The J. M. Smucker Company’s (“Smucker”) pet food business, including brands such as Rachael Ray Nutrish, Nature’s Recipe, 9Lives, Kibbles ’n Bits and Gravy Train, private label pet food assets and certain manufacturing and distribution facilities (collectively, “Pet Food”), which is reported in our Post Consumer Brands segment. In connection with the Pet Food acquisition, we entered into a transition services agreement with Smucker (the “TSA”) pursuant to which Smucker provides certain Pet Food support services to us for a transition period of 18 months (or up to 24 months at our election) following the close of the acquisition based on the terms set forth in the TSA. Pet Food receivables and payables are settled between us and Smucker monthly on a net basis per the terms of the TSA.

For additional information on these acquisitions, refer to Note 4 within “Notes to Condensed Consolidated Financial Statements.”

Market and Company Trends

Our Company, as well as the consumer packaged goods industry in which we operate, have been impacted by the following trends which have impacted our results of operations and may continue to impact our results of operations in the future, including:

•inflationary pressures on input costs across all segments of our business. During fiscal 2023, input cost inflation put downward pressures on our profit margins, which we largely mitigated through pricing actions across all segments, cost savings measures and hedging programs. During fiscal 2024, inflationary pressures on certain input costs have eased, while other input costs have continued to face inflationary pressures, and we expect this trend to continue during the remainder of fiscal 2024; and

•outbreaks of avian influenza, which impacted our Foodservice and Refrigerated Retail segments. During fiscal 2023, we incurred increased costs as a result of outbreaks, which were mitigated through management of volume needs with customers and pricing actions. During fiscal 2024, we experienced additional outbreaks of avian influenza; however, the impact to our results of operations during the three and nine months ended June 30, 2024 were not material. The impact from these outbreaks, or further outbreaks in the future, could have a materially adverse impact on our results of operations if we are unable to mitigate the impact on our businesses.

General Corporate Expenses and Other

	Three Months Ended June 30,				Change in				Nine Months Ended June 30,				Change in
dollars in millions	2024		2023		$		%		2024		2023		$		%
General corporate expenses and other	$	41.9	$	52.3	$	(10.4)	(20)	%	$	145.9	$	139.9	$	6.0	4	%

General corporate expenses and other decreased $10.4 million, or 20%, for the three months ended June 30, 2024, when compared to the prior year period. This decrease was driven by decreased acquisition-related costs of $13.1 million, primarily due to lapping Pet Food acquisition costs in the prior year, and increased net gains related to mark-to-market adjustments on economic hedges of $11.8 million (compared to net losses in the prior year period). These positive impacts were partially offset by lapping a prior year gain related to the write-off of deferred underwriting commissions of $10.7 million and increased restructuring and facility closure costs (including accelerated depreciation) of $2.3 million primarily related to our Post Consumer Brands segment.

General corporate expenses and other increased $6.0 million, or 4%, for the nine months ended June 30, 2024, when compared to the prior year period. This increase was driven by increased restructuring and facility closure costs (including accelerated depreciation) of $19.4 million primarily related to our Post Consumer Brands segment, decreased net gains related to mark-to-market adjustments on equity securities of $11.2 million, lapping a prior year gain related to the write-off of deferred underwriting commissions of $10.7 million and higher employee-related expenses of $6.8 million. These negative impacts were partially offset by increased net gains related to mark-to-market adjustments on economic hedges of $25.0 million (compared to net losses in the prior year period), decreased acquisition-related costs of $13.3 million primarily due to lapping Pet Food acquisition costs in the prior year and a gain on bargain purchase of $5.8 million related to our Deeside acquisition.

LIQUIDITY AND CAPITAL RESOURCES

We completed the following activities during the nine months ended June 30, 2024 (for additional information, see Notes 13 and 16 within “Notes to Condensed Consolidated Financial Statements”) impacting our liquidity and capital resources:

•$1,000.0 million principal value issued of 6.25% senior secured notes (the “6.25% senior notes”);

•entered into a third amendment to our second amended and restated credit agreement dated March 18, 2020 (the “Credit Agreement” and such amendment, the “Third Amendment”), which replaced our previous revolving credit facility in an aggregate principal amount of $750.0 million (the “Old Revolving Credit Facility”), with a new revolving credit facility in an aggregate principal amount of $1,000.0 million (the “New Revolving Credit Facility”), and extended the maturity date of the New Revolving Credit Facility to February 20, 2029, provided that certain criteria are met;

•$645.0 million borrowed under our Revolving Credit Facility, which such term refers to our Old Revolving Credit Facility prior to the Third Amendment and our New Revolving Credit Facility subsequent to the Third Amendment;

•$345.0 million repaid under our Revolving Credit Facility;

•$459.3 million principal value of our 5.75% senior notes redeemed at a premium of $4.4 million;

•$69.1 million principal value of our 4.50% senior notes repurchased at a discount of $7.9 million;

•$400.0 million principal value repaid on our fourth incremental term loan under our Credit Agreement (the “Fourth Incremental Term Loan”);

•2.5 million shares of our common stock repurchased at an average share price of $100.71 per share and at a total cost, including accrued excise tax and broker’s commissions, of $254.5 million; and

31

•$50.0 million paid and $50.9 million received related to a structured share repurchase contract.

Historically, we have generated and expect to continue to generate positive cash flows from operations. We believe our cash on hand, cash flows from operations and current and possible future credit facilities will be sufficient to satisfy our working capital requirements, purchase commitments, interest payments, research and development activities, capital expenditures, pension contributions and benefit payments and other financing requirements for the foreseeable future. We are currently not aware of any existing trends or demands, commitments, events or uncertainties that will result in, or that are reasonably likely to result in, our liquidity increasing or decreasing in any material way that will impact meeting our capital needs during or beyond the next twelve months. Our ability to generate positive cash flows from operations is dependent on general economic conditions, competitive pressures and other business risk factors. We believe that we have sufficient liquidity and cash on hand to satisfy our cash needs. If we are unable to generate sufficient cash flows from operations, or are otherwise unable to comply with the terms of our credit facilities, we may be required to seek additional financing alternatives, which may require waivers under our Credit Agreement and our indentures governing our senior notes, in order to generate additional cash. There can be no assurance that we would be able to obtain additional financing or any such waivers on terms acceptable to us or at all. For additional information on our debt, refer to Note 13 within “Notes to Condensed Consolidated Financial Statements.”

Short-term financing needs primarily consist of working capital requirements and interest payments on our long-term debt. Long-term financing needs will depend largely on potential growth opportunities, including acquisition activity and other strategic transactions and repayment or refinancing of our long-term debt obligations. We may, from time to time, seek to retire or purchase our outstanding debt through cash purchases in open market transactions, privately negotiated transactions or otherwise. Additionally, we may seek to repurchase shares of our common stock. Such repurchases, if any, will depend on prevailing market conditions, our liquidity requirements, contractual restrictions and other factors. The amounts involved may be material.

Obligations under our Credit Agreement are unconditionally guaranteed by our existing and subsequently acquired or organized subsidiaries (other than immaterial subsidiaries, certain excluded subsidiaries and subsidiaries we designate as unrestricted subsidiaries, which include 8th Avenue Food & Provisions, Inc. (“8th Avenue”) and its subsidiaries) and are secured by security interests in substantially all of our assets and the assets of our subsidiary guarantors, but excluding, in each case, real property. These guarantees are subject to release in certain circumstances.

Our senior notes, other than our 6.25% senior notes, are fully and unconditionally guaranteed, jointly and severally, on a senior unsecured basis by each of our existing and subsequently acquired or organized wholly-owned domestic subsidiaries (other than immaterial subsidiaries, certain excluded subsidiaries and subsidiaries we designate as unrestricted subsidiaries, which include 8th Avenue and its subsidiaries). Our 6.25% senior notes are fully and unconditionally guaranteed, jointly and severally, on a senior secured basis by each of our existing and subsequently acquired or organized wholly-owned domestic subsidiaries that guarantee the Credit Agreement or certain of our other indebtedness (other than immaterial subsidiaries, certain excluded subsidiaries and subsidiaries we designate as unrestricted subsidiaries, which include 8th Avenue and its subsidiaries). These guarantees are subject to release in certain circumstances.

Our 2.50% convertible senior notes are fully and unconditionally guaranteed, jointly and severally, on a senior unsecured basis by each of our existing domestic subsidiaries that have guaranteed our other senior notes, which excludes certain immaterial subsidiaries, certain excluded subsidiaries and subsidiaries we designate as unrestricted subsidiaries under our other senior notes indentures, which include 8th Avenue and its subsidiaries. If, after the date our 2.50% convertible senior notes were issued, any domestic wholly-owned subsidiary guarantees any of our existing senior notes or any other debt securities we may issue in the form of senior unsecured notes or convertible or exchangeable notes, then we must cause such subsidiary to become a guarantor under the 2.50% convertible senior notes as well.

Operating Activities

Cash provided by operating activities for the nine months ended June 30, 2024 increased $215.8 million compared to the prior year period. This increase was primarily driven by lapping inventory cash outflows in the prior year period within our Post Consumer Brands and Foodservice segments, cash inflows related to fluctuations in timing of purchases and payments of trade payables within our Post Consumer Brands and Refrigerated Retail segments and increased net cash receipts on our interest rate swaps of $17.3 million. These positive impacts were partially offset by higher interest payments of $8.8 million and higher tax payments of $32.4 million.

Investing Activities

Nine months ended June 30, 2024

Cash used in investing activities for the nine months ended June 30, 2024 was $538.3 million, primarily driven by net cash payments of $248.1 million related to the Perfection and Deeside acquisitions and capital expenditures of $290.3 million. Capital expenditures in the period primarily related to ongoing projects in our Post Consumer Brands and Foodservice segments.

Nine months ended June 30, 2023

Cash used in investing activities for the nine months ended June 30, 2023 was $567.9 million, primarily driven by net cash payments of $715.2 million related to the Pet Food acquisition and capital expenditures of $201.9 million. Capital expenditures in the period primarily related to ongoing projects in our Post Consumer Brands and Foodservice segments. These cash outflows were partially offset by a return of $345.0 million in connection with the PHPC Redemption which had been deposited in a trust account in connection with the PHPC IPO and the PHPC Private Placement.

Financing Activities

Nine months ended June 30, 2024

Cash provided by financing activities for the nine months ended June 30, 2024 was $66.7 million. We received proceeds of $1,000.0 million from the issuance of our 6.25% senior notes and $645.0 million from borrowings under our Revolving Credit Facility. In addition, we received net proceeds of $0.9 million related to our structured share repurchase contract. We redeemed $459.3 million principal value of our 5.75% senior notes, repaid $69.1 million principal value of our 4.50% senior notes (net of $7.9 million of discounts), repaid $400.0 million principal value of our Fourth Incremental Term Loan, repaid $345.0 million under our Revolving Credit Facility and repaid $1.1 million principal value of our municipal bond, which resulted in total net repayments of debt of $1,266.6 million. We paid $248.7 million, including broker’s commissions, for the repurchase of shares of our common stock. In addition, we paid $19.9 million of debt issuance costs and deferred financing fees in connection with the issuance of our 6.25% senior notes and entry into the Third Amendment and $4.4 million of debt premiums related to the redemption of our 5.75% senior notes.

Nine months ended June 30, 2023

Cash used in financing activities for the nine months ended June 30, 2023 was $279.7 million. We received proceeds of $400.0 million and $130.0 million from our Fourth Incremental Term Loan and our Third Incremental Term Loan, respectively. The Third Incremental Term Loan was partially repaid through a debt-for-equity exchange of the remaining shares of BellRing Brands, Inc. (“BellRing”) common stock we held from our previous transactions related to the distribution of a portion of our interest in BellRing, and the remaining principal balance of $30.1 million was repaid using cash on hand. In addition, we repaid $170.5 million principal value of our 4.50% and 4.625% senior notes (net of $23.3 million of discounts) and $1.1 million principal value of our municipal bond, which resulted in total net repayments of debt of $178.4 million. We distributed $312.5 million to PHPC public stockholders in connection with the PHPC Redemption. We paid $242.4 million, including broker’s commissions, for the repurchase of shares of our common stock and $43.5 million related to the termination of certain of our rate-lock interest rate swap contracts, which contained non-cash, off-market financing elements.

Debt Covenants

Under the terms of our Credit Agreement, we are required to comply with a financial covenant consisting of a secured net leverage ratio (as defined in the Credit Agreement) not to exceed 4.25 to 1.00 measured as of the last day of any fiscal quarter if, as of the last day of such fiscal quarter, the aggregate outstanding amount of all revolving credit loans, swing line loans and letter of credit obligations (subject to certain exceptions specified in the Credit Agreement) exceeds 30% of our revolving credit commitments. As of June 30, 2024, we were in compliance with this financial covenant. We do not believe non-compliance is reasonably likely in the foreseeable future.

Our Credit Agreement provides for incremental revolving and term loan facilities, and also permits other secured or unsecured debt, if, among other conditions, certain financial ratios are met, as defined and specified in the Credit Agreement.

CRITICAL ACCOUNTING ESTIMATES

Our critical accounting estimates are more fully described in our Annual Report on Form 10-K for the year ended September 30, 2023, as filed with the Securities and Exchange Commission (the “SEC”) on November 17, 2023.

ITEM 3.    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

Commodity Price Risk

In the ordinary course of business, the Company is exposed to commodity price risks relating to the acquisition of raw materials, including ingredients and packaging, energy and fuel. The Company may use futures contracts and options to manage certain of these exposures when it is practical to do so. A hypothetical 10% adverse change in the market price of the Company’s principal hedged commodities, including natural gas, heating oil, soybean oil, corn, wheat and dairy, would have decreased the fair value of the Company’s commodity-related derivatives portfolio by approximately $1 million and $5 million as of June 30, 2024 and September 30, 2023, respectively. This volatility analysis ignores changes in the exposures inherent in the underlying hedged transactions. Because the Company does not hold or trade derivatives for speculation or profit, all changes in derivative values are effectively offset by corresponding changes in the underlying commodity exposures.

For more information regarding the Company’s commodity derivative contracts, refer to Note 11 within “Notes to Condensed Consolidated Financial Statements.”

Foreign Currency Risk

Related to its foreign subsidiaries, the Company is exposed to risks of fluctuations in future cash flows and earnings due to changes in foreign currency exchange rates. To mitigate these risks, the Company uses a combination of foreign currency exchange contracts, which may consist of options, forward contracts and currency swaps. As of both June 30, 2024 and September 30, 2023, a hypothetical 10% change in the expected Euro-GBP foreign currency exchange rates would have changed the fair value of the Company’s foreign currency-related derivatives portfolio by an immaterial amount.

For additional information regarding the Company’s foreign currency derivative contracts, refer to Note 11 within “Notes to Condensed Consolidated Financial Statements.”

Interest Rate Risk

Long-term debt

As of June 30, 2024, the Company had outstanding principal value of indebtedness of $6,420.1 million related to its senior notes, borrowings outstanding under its Revolving Credit Facility and a municipal bond. At June 30, 2024, the Company’s

35

Revolving Credit Facility had available borrowing capacity of $680.0 million. Of the total $6,420.1 million of outstanding indebtedness, $6,115.9 million bore interest at a weighted-average fixed interest rate of 5.0%. As of September 30, 2023, the Company had principal value of indebtedness of $6,049.6 million related to its senior notes, the Fourth Incremental Term Loan and a municipal bond, and the Revolving Credit Facility had available borrowing capacity of $730.3 million. Of the total $6,049.6 million of outstanding indebtedness, $5,644.3 million bore interest at a weighted-average fixed interest rate of 4.8%.

As of June 30, 2024 and September 30, 2023, the fair value of the Company’s debt, excluding any outstanding borrowings under the Revolving Credit Facility and the municipal bond, was $5,904.7 million and $5,491.5 million, respectively. Changes in interest rates impact fixed and variable rate debt differently. For fixed rate debt, a change in interest rates will only impact the fair value of the debt, whereas a change in interest rates on variable rate debt will impact interest expense and cash flows. A hypothetical 10% decrease in interest rates would have increased the fair value of the fixed rate debt by approximately $114 million and $112 million as of June 30, 2024 and September 30, 2023, respectively. A hypothetical 10% increase in interest rates would have had an immaterial impact on both interest expense and interest paid on variable rate debt during each of the three and nine months ended June 30, 2024 and 2023.

For additional information regarding the Company’s debt, refer to Note 13 within “Notes to Condensed Consolidated Financial Statements.”

Interest rate swaps

As of June 30, 2024 and September 30, 2023, the Company had interest rate swaps with a notional value of $300.0 million and $700.0 million, respectively. A hypothetical 10% increase in interest rates would have decreased the fair value of the interest rate swaps by approximately $10 million and $15 million as of June 30, 2024 and September 30, 2023, respectively.

For additional information regarding the Company’s interest rate swap contracts, refer to Note 11 within “Notes to Condensed Consolidated Financial Statements.”

ITEM 4.    CONTROLS AND PROCEDURES.

Evaluation of Disclosure Controls and Procedures

Management, with the Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”) of the Company, has evaluated the effectiveness of the Company’s disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended) as of the end of the period covered by this report. Based on that evaluation, the Company’s CEO and CFO concluded that, as of the end of the period covered by this report, the Company’s disclosure controls and procedures were effective to provide reasonable assurance of achieving the desired control objectives.

Changes in Internal Control Over Financial Reporting

In connection with the Company’s Perfection acquisition completed in fiscal 2024, management is in the process of analyzing, evaluating and, where necessary, implementing changes in controls and procedures. This process may result in additions or changes to the Company’s internal control over financial reporting. Based on management’s evaluation, there were no other significant changes in the Company’s internal control over financial reporting during the quarter ended June 30, 2024 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

PART II.    OTHER INFORMATION.

ITEM 1.     LEGAL PROCEEDINGS.

For information regarding our legal proceedings, refer to “Legal Proceedings” in Note 14 within “Notes to Condensed Consolidated Financial Statements” in Item 1 of Part I of this report, which is incorporated herein by reference.

Pursuant to Securities and Exchange Commission (“SEC”) regulations, the Company is required to disclose certain information about environmental proceedings with a governmental entity as a party if the Company reasonably believes such proceedings may result in monetary sanctions, exclusive of interest and costs, above a stated threshold. Pursuant to such SEC regulations, the Company has elected to use a threshold of $1.0 million for purposes of determining whether disclosure of any such proceedings is required. Applying this threshold, there are no such environmental proceedings to disclose for the period covered by this report.

ITEM 1A.    RISK FACTORS.

In addition to the information set forth elsewhere in this Quarterly Report on Form 10-Q (the “Quarterly Report”), you should carefully consider the risk factors we previously disclosed in our Annual Report on Form 10-K for the fiscal year ended

36

September 30, 2023, filed with the SEC on November 17, 2023 (the “Annual Report”). As of the date of the Quarterly Report, there have been no material changes to the risk factors previously disclosed in the Annual Report. These risks could materially and adversely affect our businesses, financial condition, results of operations and cash flows. Such enumerated risks are not the only risks we face. Additional risks and uncertainties not presently known to us or that we currently deem immaterial also may impair our businesses, financial condition, results of operations and cash flows.

ARTICLE FIVE – DIRECTORS

A.Number and Classification

The number of directors shall be fixed by, or in the manner provided in, the Bylaws of the Corporation, but shall not be less than three. Commencing at the 2025 annual meeting of shareholders, all of the directors of the Corporation elected at an annual meeting of shareholders shall hold office for a term that expires at the next annual meeting of shareholders (or until their respective successors shall have been elected and qualified or until their earlier death, resignation or removal). The term of each director serving as of and immediately following the date of the 2024 annual meeting of shareholders shall expire at the 2025 annual meeting of shareholders, notwithstanding that such director may have been elected for a term that extended beyond the date of the 2025 annual meeting of shareholders. Notwithstanding the foregoing, whenever the holders of any one or more classes or series of stock of the Corporation, other than shares of Common Stock, shall have the right, voting separately by class or series, to elect directors, the election, term of office, filling of vacancies and other features of such directorship shall be governed by the terms of these Amended and Restated Articles of Incorporation or any Certificate of Designation thereunder applicable thereto. As used in these Amended and Restated Articles of Incorporation, the term “entire Board of Directors” means the total number of directors fixed by, or in accordance with, these Articles of Incorporation and the Bylaws of the Corporation.

B.Removal of Directors

At a meeting called expressly for that purpose, one or more members of the Board of Directors may be removed only for cause and only by the affirmative vote of a least (i) two-thirds of all members of the Corporation’s Board of Directors, and (ii) two-thirds of all of the then outstanding shares of capital stock of the Corporation then entitled to vote generally in the election of directors, voting together as a single class (such vote being in addition to any required class or other vote). Whenever the holders of the shares of any class are entitled to elect one or more directors, the provisions of this Article shall apply in respect of the removal of a director or directors so elected, to the vote of the holders of the outstanding shares of that class and not to vote the holders of the outstanding shares as a whole. In addition, any director may be removed from office by the affirmative vote of a majority of the entire Board of Directors at any time prior to the expiration of the director’s term of office, as provided by law, in the event that the director fails, at the time of removal, to meet any qualifications stated in the Bylaws of the Corporation for election as a director or shall be in breach of any agreement between the director and the Corporation relating to the director’s service as a director or employee of the Corporation.

C.Vacancies

Subject to the rights, if any, of the holders of any class of capital stock of the Corporation (other than the Common Stock) then outstanding, any vacancies in the Board of Directors which occur for any reason prior to the expiration of the term of office of any director, including vacancies which occur by reason of an increase in the number of directors, may be filled only by the Board of Directors, acting by the affirmative vote of a majority of the remaining directors then in office (although less than a quorum), until the next election of directors by the shareholders of the Corporation.

D.Amendment

This Article Five may be amended, altered, changed or repealed only upon the affirmative vote of not less than two-thirds of all of the outstanding shares of capital stock of the Corporation then entitled to vote generally in the election of directors voting together as a single class; provided, however, that whenever the holders of

shares of any class are entitled to elect one or more directors, such amendment, alternation, change or repeal shall also require the affirmative vote of not less than two-thirds of the outstanding shares of each such class entitled to vote at such meeting.

ARTICLE SIX – TERM OF EXISTENCE

The Corporation shall have a perpetual existence.

ARTICLE SEVEN – PURPOSES

The purposes of the Corporation are to engage in any lawful act or activity for which a corporation now or hereafter may be organized under the GBCL.

ARTICLE EIGHT – BYLAWS

The Bylaws of the Corporation may be amended, altered, changed or repealed in the manner provided for in the Bylaws.

ARTICLE NINE – CERTAIN BUSINESS COMBINATIONS

A.Approval

The approval of any Business Combination shall, in addition to any affirmative vote otherwise required by the GBCL, require the recommendation of the Board of Directors and the affirmative vote of the holders of not less than 85% of all of the outstanding shares of the capital stock of the Company then entitled to vote at a meeting of shareholders called for such purpose of which an Interested Shareholder is not the Beneficial Owner; provided, however, that, notwithstanding the foregoing, any such Business Combination may be approved on any affirmative vote required by the GBCL if:

(a)There are one or more Continuing Directors and the Business Combination shall have been approved by a majority of them; or

(b)(1) The consideration to be received by shareholders of each class of stock of the Corporation shall be in cash or in the same form as the Interested Shareholder and its affiliates have previously paid for a majority of the shares of such class of stock owned by the Interested Shareholder; and (2) the cash, or Market Value of the property, securities or other shareholders of each class of stock of the Corporation in the Business Combination is not less than the higher of:

(i)the highest per share price paid by the Interested Shareholder for the acquisition of any shares of such class in the two years immediately preceding the announcement date of the Business Combination, with appropriate adjustments for stock splits, stock dividends and like distributions, or

(ii)the Market Value of such shares, on the date the Business Combination is approved by the Board of Directors.

B.Definitions

(a)For purposes of this Article Nine, any terms not otherwise defined herein shall have the meanings set forth in Section 351.459 of the GBCL as in effect on the date these Amended and Restated Articles of Incorporation become effective.

(b)The term “Continuing Director” shall mean any member of the Board of Directors of the Corporation who is not an Affiliate or Associate of the Interested Shareholder and who was a member of the Board of Directors prior to the time that the Interested Shareholder became an Interested Shareholder, and any successor of a Continuing Director if the successor is not an Affiliate or Associate of the Interested Shareholder and is recommended or elected to succeed a Continuing Director by a majority of Continuing Directors.

C.Amendment

This Article Nine may be amended, altered, changed or repealed only upon the affirmative vote of not less than 85% of all the outstanding shares of capital stock of the Corporation entitled to vote at a meeting called for such purpose of which an Interested Shareholder is not the Beneficial Owner; provided, however, that this Article may be amended, altered, changed or repealed upon the affirmative vote required by the GBCL, if such amendment, alternation, change or repeal has been approved by a majority of the Board of Directors, if there is not an Interested Shareholder, or if there is an Interested Shareholder, by a majority of the Continuing Directors.

D.Article Inapplicable to Ralcorp Holdings, Inc.

This Article Nine shall not apply to any transactions with Ralcorp Holdings, Inc, a Missouri corporation or its subsidiaries, in connection with the Separation and Distribution Agreement by and among Ralcorp, the Corporation and Post Foods, LLC, a Delaware limited liability company, or any agreement or matter provided for therein or contemplated thereby.

ARTICLE TEN – INDEMNIFICATION OF DIRECTORS, OFFICERS AND OTHERS

A.Actions Involving Directors and Officers

The Corporation shall indemnify each person (other than a party plaintiff suing on his or her behalf or in the right of the Corporation) who at any time is serving or has served as a director or officer of the Corporation against any claim, liability or expense incurred as a result of such service, or as a result of any other service on behalf of the Corporation, or service at the request of the Corporation as a director, officer, employee, member, or agent of another corporation, partnership, joint venture, trust, trade or industry association, or other enterprise (whether incorporated or unincorporated, for-profit or not-for-profit), to the maximum extent permitted by law. Without limiting the generality of the foregoing, the Corporation shall indemnify any such person who was or is a party (other than a party plaintiff suing on his or her behalf or in the right of the Corporation), or is threatened to be made a party, to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (including, but not limited to, an action by or in the right of the Corporation) by reason of such service, against expenses (including, without limitation, attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him or her in connection with such action, suit or proceeding.

B.Actions Involving Employees or Agents

1.Permissive Indemnification. The Corporation may, if it deems appropriate and as may be permitted by this Article Ten, indemnify any person (other than a party plaintiff suing on his or her own behalf or in the right of the Corporation) who at any time is serving or has served as an employee or agent of the Corporation against any claim, liability or expense incurred as a result of such service, or as a result of any other service on behalf of the Corporation, or service at the request of the Corporation as a director, officer, employee, member, or agent of another corporation, partnership, joint venture, trust, trade or industry association, or other enterprise (whether incorporated or unincorporated, for-profit or not-for-profit), to the maximum extent permitted by law or to such lesser extent as the Corporation, in its discretion, may deem appropriate. Without limiting the generality of the foregoing, the Corporation may indemnify any such person who was or is a party (other than a party plaintiff suing on his or her own behalf or in the right of the Corporation), or is threatened to be made a party, to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (including, but not limited to, an action by or in the right of the Corporation) by reason of such service, against expenses (including, without limitation, attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him or her in connection with such action, suit or proceeding.

2.Mandatory Indemnification. To the extent that an employee or agent of the Corporation has been successful on the merits or otherwise in defense of any action, suit or proceeding referred to in Section B.1 of this Article Ten, or in defense of any claim, issue or matter therein, he or she shall be indemnified against expenses (including, without limitation, attorneys’ fees) actually and reasonably incurred by him or her in connection with the action, suite or proceeding.

C.Determination of Right to Indemnification in Certain Circumstances

Any indemnification required under Section A of this Article Ten or authorized by the Corporation in a specific case pursuant to Section B of this Article Ten (unless ordered by a court) shall be made by the Corporation unless a determination is made reasonably and promptly that indemnification of the director, officer, employee or agent is not proper under the circumstances because he or she has not met the applicable standard of conduct set forth in or established pursuant to this Article Ten. Such determination shall be made (1) by the Board of Directors by a majority vote of a quorum consisting of directors who were not parties to such action, suit or proceeding, or

(2) if such a quorum is not obtainable, or even if obtainable a quorum of disinterested directors so directs, by independent legal counsel in a written opinion, or (3) by majority vote of the shareholders; provided that no such determination shall preclude an action brought in an appropriate court to challenge such determination.

D.Standard of Conduct

Except as may otherwise be permitted by law, no person shall be indemnified pursuant to this Article Ten (including without limitation pursuant to any agreement entered into pursuant to Section G of this Article Ten) from or on account of such person’s conduct which is finally adjudged to have been knowingly fraudulent, deliberately dishonest or willful misconduct. The Corporation may (but need not) adopt a more restricted standard of conduct with respect to the indemnification of any employee or agent of the Corporation.

E.Advance Payment of Expenses

Expenses incurred by a person who is or was a director or officer of the Corporation in defending a civil or criminal action, suit, proceeding or claim shall be paid by the Corporation in advance of the final disposition of such

action, suit, proceeding or claim, and expenses incurred by a person who is or was an employee or agent of the Corporation in defending a civil or criminal action, suit, proceeding or claim may be paid by the Corporation in advance of the final disposition of such action, suit, proceeding or claim as authorized by or at the direction of the Board of Directors, in either case upon receipt of an undertaking by or on behalf of the director, officer, employee or agent to repay such amount if it shall ultimately be determined that such person is not entitled to be indemnified by the Corporation as authorized in or pursuant to this Article Ten.

F.Rights Not Exclusive

The indemnification and other rights provided by this Article Ten shall not be deemed exclusive of any other rights to which those seeking indemnification may be entitled under any agreement, vote of shareholders or disinterested directors or otherwise, and the Corporation is hereby specifically authorized to provide such indemnification and other rights by any agreement, vote of shareholders or disinterested directors or otherwise.

G.Indemnification Agreements Authorized

Without limiting the other provisions of this Article Ten, the Corporation is authorized from time to time, without further action by the shareholders of the Corporation, to enter into agreements with any director, officer, employee or agent of the Corporation providing such rights of indemnification as the Corporation may deem appropriate, up to the maximum extent permitted by law. Any agreement entered into by the Corporation with a director may be authorized by the other directors, and such authorization shall not be invalid on the basis that similar agreements may have been or may thereafter be entered into with other directors.

H.Insurance

The Corporation may purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the Corporation, or who is or was otherwise serving on behalf of the Corporation in any capacity or at the request of the Corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust, trade or industry association or other enterprise (whether incorporated or unincorporated, for-profit or not-for-profit) against any claim, liability or expense asserted against such person and incurred by such person in any such capacity or arising out of such person’s status as such, whether or not the Corporation would have the power to indemnify such person against such liability under the provisions of this Article Ten.

I.Certain Definitions

For the purpose of this Article Ten:

(i)Any director, officer, employee or agent of the Corporation who shall serve as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise of which the Corporation, directly or indirectly, is or was the owner of 20% or more of the outstanding voting stock (or comparable interests), shall be deemed to be so serving at the request of the Corporation, unless the Board of Directors of the Corporation shall determine otherwise. In all other instances when any person shall serve as a director, officer, employee or agent of another corporation, partnership, joint venture, trust, trade or industry association or other enterprise of which the Corporation is or was a stockholder or creditor, or in which it is or was otherwise interested, if it is not otherwise established that such person is or was serving as a director, officer, employee or agent at the request of the Corporation, the Board of Directors of

the Corporation may determine whether such service is or was at the request of the Corporation, and it shall not be necessary to show any actual or prior request for such service.

(ii)References to a corporation include all constituent corporations absorbed in a consolidation or merger as well as the resulting or surviving corporation so that any person who is or was a director, officer, employee or agent of a constituent corporation or is or was serving at the request of a constituent corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust, trade or industry association or other enterprise shall stand in the same position under the provisions of this Article Ten with respect to the resulting or surviving corporation as such person would if such person had served the resulting or surviving corporation in the same capacity.

(iii)The term “other enterprise” shall include, without limitation, employee benefit plans and voting or taking action with respect to stock or other assets therein; the term “serving at the request of the Corporation” shall include, without limitation, any service as a director, officer, employee or agent of a corporation which imposes duties on , or involves services by, a director, officer, employee or agent of the Corporation with respect to any employee benefit plan, its participants, or beneficiaries; and unless a person’s conduct in connection with an employee benefit plan is finally adjudicated to have been knowingly fraudulent, deliberately dishonest or willful misconduct, such person shall be deemed to have satisfied any standard of care required by or pursuant to this Article Ten in connection with such plan; the term “fines” shall include, without limitation, any excise taxes assessed on a person with respect to an employee benefit plan and shall also include any damages (including treble damages) and any other civil penalties.

J.Survival

The indemnification and other rights provided pursuant to this Article Ten shall apply both to action by any director, officer, employee or agent of the Corporation in an official capacity and to action in another capacity while holding such office or position and shall continue as to a person who has ceased to be a director, officer, employee or agent of the Corporation and shall inure to the benefit of the heirs, executors and administrators of such a person. Notwithstanding any other provision in these Amended and Restated Articles of Incorporation, any indemnification rights arising under or granted pursuant to this Article Ten shall survive amendment or repeal of this Article Ten with respect to any acts or omissions occurring prior to the effective time of such amendment or repeal and persons to whom such indemnification rights are given shall be entitled to rely upon such indemnification rights with respect to such acts or omissions as a binding contract with the Corporation.

K.Liability of the Directors

It is the intention of the Corporation to limit the liability of the directors of the Corporation, in their capacity as such, whether to the Corporation, its shareholders or otherwise, to the fullest extent permitted by law. Consequently, should the GBCL or any other applicable law be amended or adopted hereafter so as to permit the elimination or limitation of such liability, the liability of the directors of the Corporation shall be so eliminated or limited without the need for amendment of these Amended and Restated Articles of Incorporation or further action on the part of the shareholders of the Corporation.

L.Amendment

This Article Ten may be amended, altered, changed or repealed only upon the affirmative vote of not less than 85% of all of the outstanding shares of capital stock of the Corporation then entitled to vote generally in the election of directors voting together as a single class.

ARTICLE ELEVEN – AMENDMENT OF ARTICLES OF INCORPORATION

The Corporation reserves the right to amend, alter, change or repeal any provision contained in these Amended and Restated Articles of Incorporation in the manner prescribed herein for amendment of such provision and if not so prescribed then in the manner now or hereafter prescribed by law and all rights and powers conferred herein on shareholders, directors and officers of the Corporation are subject to this reserved power.

Equity Method Investments and Joint Ventures [Abstract]

Equity Method Investments and Joint Ventures Disclosure - 8th Ave

8th Avenue

The Company has a 60.5% common equity interest in 8th Avenue Food & Provisions, Inc. (“8th Avenue”) that is accounted for using the equity method. In determining the accounting treatment of the common equity interest, management concluded that 8th Avenue was not a variable interest entity as defined by Accounting Standards Codification (“ASC”) Topic 810, “Consolidation,” and as such, 8th Avenue was evaluated under the voting interest model. Based on the terms of 8th Avenue’s governing documents, management determined that the Company does not have a controlling voting interest in 8th Avenue due to substantive participating rights held by third parties associated with the governance of 8th Avenue. However, Post does retain significant influence, and therefore, the use of the equity method of accounting is required.

During fiscal 2022, 8th Avenue’s equity method loss attributable to Post exceeded the Company’s remaining investment in 8th Avenue. As such, in accordance with ASC Topic 323, “Investments—Equity Method and Joint Ventures,” the Company discontinued applying the equity method to the investment after reducing the balance of the investment to zero. The Company’s investment in 8th Avenue was zero at both June 30, 2024 and September 30, 2023, and the Company did not recognize an equity method gain (loss) attributable to 8th Avenue for the three or nine months ended June 30, 2024 or 2023.

During the three and nine months ended June 30, 2024, the Company had net sales to 8th Avenue of $1.5 and $5.3, respectively, and purchases from and royalties paid to 8th Avenue of $21.5 and $61.1, respectively. During the three and nine months ended June 30, 2023, the Company had net sales to 8th Avenue of $1.2 and $6.7, respectively, and purchases from and royalties paid to 8th Avenue of $16.8 and $65.2, respectively. Sales and purchases between the Company and 8th Avenue were all made at arm’s-length.

The Company had current payables with 8th Avenue of $15.6 and $13.3 at June 30, 2024 and September 30, 2023, respectively, which were included in “Accounts payable” on the Condensed Consolidated Balance Sheets and primarily related to related party purchases and royalties. Current receivables with 8th Avenue at June 30, 2024 and September 30, 2023 were immaterial. In addition, the Company had a long-term receivable and a long-term liability with 8th Avenue of $12.9 and $0.7, respectively, at both June 30, 2024 and September 30, 2023, which were included in “Other assets” and “Other liabilities,” respectively, on the Condensed Consolidated Balance Sheets and related to tax indemnifications.

Weetabix East Africa is a Kenyan-based company that produces ready-to-eat (“RTE”) cereal and muesli. The Company owns 50.1% of Weetabix East Africa and holds a controlling voting and financial interest through its appointment of management and representation on Weetabix East Africa’s board of directors. Accordingly, Weetabix East Africa is fully consolidated into the Company’s financial statements and its assets and results of operations are reported in the Weetabix segment. The remaining interest in the consolidated net earnings and net assets of Weetabix East Africa is allocated to NCI.

The Company holds an equity interest in Alpen Food Company South Africa (Pty) Limited (“Alpen”). Alpen is a South African-based company that produces RTE cereal and muesli. The Company owns 50.0% of Alpen’s common stock with no other indicators of control, and accordingly, the Company accounts for its investment in Alpen using the equity method.

Equity Method Investments and Joint Ventures Disclosure - BRBR

BellRing

Transactions between the Company and BellRing Brands, Inc. (“BellRing”) are considered related party transactions as certain of the Company’s officers and/or directors serve as officers and/or directors of BellRing.

On September 30, 2022, Comet Processing, Inc. (“Comet”), a wholly-owned subsidiary of the Company, entered into a co-packing agreement with Premier Nutrition Company, LLC (“Premier Nutrition”), a subsidiary of BellRing (the “Co-Packing Agreement”). Under the Co-Packing Agreement, Premier Nutrition procures certain packaging materials for Comet that Comet utilizes in the production of ready-to-drink (“RTD”) shakes for Premier Nutrition. In December 2023, in accordance with the terms of the Co-Packing Agreement, Comet began manufacturing RTD shakes for Premier Nutrition. Sales of RTD shakes to Premier Nutrition during the three and nine months ended June 30, 2024 were immaterial and there were no sales of RTD shakes to Premier Nutrition during fiscal 2023. Other related party transactions and balances between the Company and BellRing were immaterial as of and for the three and nine months ended June 30, 2024 and 2023.

Noncontrolling Interests, Equity Interests and Related Party Transactions - PHPC

Post Holdings Partnering Corporation

In May and June 2021, the Company and Post Holdings Partnering Corporation (“PHPC”), a special purpose acquisition company, consummated the initial public offering of 34.5 units of PHPC (the “PHPC Units” and such transaction, the “PHPC IPO”), of which a wholly-owned subsidiary of the Company (“PHPC Sponsor”) purchased 4.0 PHPC Units. Each PHPC Unit consisted of one share of Series A common stock of PHPC (“PHPC Series A Common Stock”) and one-third of one redeemable warrant to purchase one share of PHPC Series A Common Stock at an exercise price of $11.50 per share (the “PHPC Warrants”). The PHPC Units were sold at a price of $10.00 per PHPC Unit, generating gross proceeds to PHPC of $345.0. Under the terms of the PHPC IPO, PHPC was required to consummate a partnering transaction by May 28, 2023, which could have been extended to August 28, 2023 in certain circumstances (the “Combination Period”).

Substantially concurrently with the closing of the PHPC IPO, PHPC completed the private sale of 1.1 units of PHPC (the “PHPC Private Placement Units”), at a purchase price of $10.00 per PHPC Private Placement Unit, to PHPC Sponsor, generating proceeds to PHPC of $10.9 (the “PHPC Private Placement”). Each PHPC Private Placement Unit consisted of one share of PHPC Series A Common Stock and one-third of one redeemable warrant of PHPC to purchase one share of PHPC Series A Common Stock at an exercise price of $11.50 per share (the “PHPC Private Placement Warrants”).

In addition, the Company, through PHPC Sponsor’s ownership of 8.6 shares of Series F common stock of PHPC (the “PHPC Series F Common Stock”), had certain governance rights in PHPC relating to the election of PHPC directors and voting rights on amendments to PHPC’s amended and restated certificate of incorporation.

PHPC Sponsor was the primary beneficiary of PHPC as it had, through its equity interest, the right to receive benefits or the obligation to absorb losses from PHPC, as well as the power to direct a majority of the activities that significantly impacted PHPC’s economic performance, including partnering transaction target identification. As such, PHPC was fully consolidated into the Company’s financial statements until the time of its dissolution, as discussed below.

Proceeds of $345.0 were deposited in a trust account established for the benefit of PHPC’s public stockholders, which consisted of certain proceeds from the PHPC IPO and certain proceeds from the PHPC Private Placement, net of underwriters’ discounts and commissions and other costs and expenses.

The public stockholders’ ownership of PHPC equity represented a noncontrolling interest (“NCI”) to the Company, which was classified outside of permanent shareholders’ equity as the PHPC Series A Common Stock was redeemable at the option of the public stockholders in certain circumstances. The carrying amount of the redeemable NCI was equal to the greater of (i) the initial carrying amount, increased or decreased for the redeemable NCI’s share of PHPC’s net earnings or loss, other comprehensive income or loss (“OCI”) and distributions or (ii) the redemption value. The redemption value represented the amount the public stockholders of PHPC Series A Common Stock would be entitled in certain circumstances to redeem their shares of PHPC Series A Common Stock for, which was a pro-rata portion of the amount in the trust account at $10.00 per share of PHPC Series A Common Stock held, plus any pro-rata interest earned on the funds held in the trust account (which interest was net of taxes payable, and less up to $0.1 of interest to pay dissolution expenses). Remeasurements to the redemption value of the redeemable NCI were recognized as a deemed dividend and recorded to retained earnings on the balance sheet prior to the PHPC Redemption (as defined below).

In connection with the PHPC IPO, PHPC incurred offering costs of $17.9, of which $10.7 were deferred underwriting commissions that would have become payable to the underwriters solely in the event that PHPC completed a partnering transaction.

Prior to the PHPC Redemption, the Company beneficially owned 31.0% of the equity of PHPC and the net earnings and net assets of PHPC were consolidated within the Company’s financial statements. The remaining 69.0% of the consolidated net earnings and net assets of PHPC, which represented the percentage of economic interest in PHPC held by the public stockholders of PHPC through their ownership of PHPC equity, were allocated to redeemable NCI. All transactions between PHPC and PHPC Sponsor, as well as related financial statement impacts, eliminated in consolidation.

On May 11, 2023, PHPC announced that it would not complete a partnering transaction within the Combination Period and that the entity would liquidate and dissolve in accordance with the terms of its amended and restated certificate of incorporation. Subsequent to the decision to liquidate and dissolve, PHPC completed certain winding-up activities, which included writing-off the deferred underwriting commissions as the underwriters agreed to waive their rights to these amounts should a partnering transaction not occur. The Company recorded a $10.7 gain in connection with this write-off, which was recorded in “Other income, net” on the Condensed Consolidated Statements of Operations during both the three and nine months ended June 30, 2023.

On May 28, 2023, the PHPC Warrants and the PHPC Private Placement Warrants expired worthless, as PHPC had not completed a partnering transaction before the expiration of the Combination Period.

On May 30, 2023, PHPC redeemed all of the outstanding public shares of PHPC Series A Common Stock (the “PHPC Redemption”). Each share of PHPC Series A Common Stock was redeemed for approximately $10.24 per share, representing the per share price equal to the aggregate amount then on deposit in the trust account, including interest earned on the trust account not previously released to pay taxes or dissolution expenses, divided by the number of then outstanding shares of PHPC Series A Common Stock. In connection with the PHPC Redemption, during the three and nine months ended June 30, 2023:

•$353.4 of funds held in the trust account immediately prior to the PHPC Redemption were distributed to redeem all of the outstanding shares of PHPC Series A Common Stock. The Company received $40.9 from the PHPC Redemption related to its ownership of 4.0 shares of PHPC Series A Common Stock; and

•redeemable NCI of $312.5 immediately prior to the PHPC Redemption was reduced to zero.

Subsequent to the PHPC Redemption, PHPC delisted from the New York Stock Exchange and dissolved in June 2023, and all classes of shares of PHPC equity were cancelled, including the PHPC Private Placement Units and the shares of the PHPC Series F Common Stock, which were surrendered by PHPC Sponsor for no consideration. PHPC Sponsor subsequently dissolved in August 2023.

Business Combinations [Abstract]

Business Combinations

BUSINESS COMBINATIONS

The Company uses the acquisition method of accounting for acquired businesses. Under the acquisition method, the Company’s financial statements reflect the operations of an acquired business starting from the date of acquisition. The assets acquired and liabilities assumed are recorded at their respective estimated fair values at the date of the acquisition based on Level 3 inputs. Any excess of the purchase price over the estimated fair values of the identifiable net assets acquired is recorded as goodwill. Any excess of the estimated fair values of the identifiable net assets acquired over the purchase price is recorded as a gain on bargain purchase. Goodwill represents the value the Company expects to achieve through the implementation of operational synergies, the expansion of the business into new or growing segments of the industry and the addition of new employees.

Fiscal 2024

On December 1, 2023, the Company completed its acquisition of substantially all of the assets of Perfection Pet Foods, LLC (“Perfection”) for $235.0, subject to working capital adjustments and other adjustments, resulting in a payment at closing of $238.8. Perfection is a manufacturer and packager of private label and co-manufactured pet food and baked treat products and is reported in the Post Consumer Brands segment. The acquisition was completed using cash on hand, including borrowings under the Revolving Credit Facility (as defined in Note 13). During the third quarter of fiscal 2024, the Company reached a final settlement of net working capital, resulting in an amount received by the Company of $4.6.

Based upon the preliminary purchase price allocation, the Company recorded $81.0 of customer relationships, which is being amortized over a weighted-average useful life of 16 years. Net sales and operating profit included in the Condensed Consolidated Statements of Operations attributable to Perfection were $62.1 and $4.2, respectively, for the three months ended June 30, 2024 and $146.7 and $9.1, respectively, for the nine months ended June 30, 2024.

Preliminary values of Perfection are measured as of the date of the acquisition, are not yet finalized pending the final purchase price allocation and are subject to change. The goodwill generated by the Company’s Perfection acquisition is expected to be deductible for U.S. income tax purposes.

The following table presents the preliminary purchase price allocation, including immaterial measurement period adjustments, related to the Perfection acquisition based upon the fair values of assets acquired and liabilities assumed as of June 30, 2024.

Cash and cash equivalents	$	0.3
Receivables, net	40.8
Inventories	21.1
Prepaid expenses and other current assets	0.4
Property, net	69.9
Other intangible assets, net	81.0

Also on December 1, 2023, the Company completed its acquisition of Deeside Cereals I Ltd (“Deeside”) for £11.3 (approximately $14.3). The acquisition was completed using cash on hand. Deeside is a producer of private label cereals in the United Kingdom (the “U.K.”) and is reported in the Weetabix segment. Based upon the preliminary purchase price allocation, the Company identified and recorded $20.5 of net assets, which exceeded the purchase price paid for Deeside. As a result, the Company recorded an initial gain on bargain purchase of $6.2 during the first quarter of fiscal 2024. During the third quarter of fiscal 2024, the Company recorded measurement period adjustments related to Deeside’s defined benefit pension plan and deferred taxes, which reduced the acquired Deeside net assets by $0.4. As a result, the Company recorded an adjustment to (gain) on bargain purchase of $0.4 and $(5.8) during the three and nine months ended June 30, 2024, respectively, which was included in “Other operating expense (income), net” in the Condensed Consolidated Statements of Operations. Net sales and operating loss included in the Condensed Consolidated Statements of Operations attributable to Deeside were $7.5 and $0.3, respectively, for the three months ended June 30, 2024 and $17.0 and $1.2, respectively, for the nine months ended June 30, 2024. Preliminary values of Deeside are measured as of the date of the acquisition, are not yet finalized pending the final purchase price allocation and are subject to change.

Acquisition-related costs for fiscal 2024 acquisitions were immaterial during the three and nine months ended June 30, 2024.

Fiscal 2023

On April 28, 2023, the Company completed its acquisition of a portion of The J. M. Smucker Company’s (“Smucker”) pet food business, including brands such as Rachael Ray Nutrish, Nature’s Recipe, 9Lives, Kibbles ’n Bits and Gravy Train, private label pet food assets and certain manufacturing and distribution facilities (collectively, “Pet Food”), facilitating the Company’s entry into the pet food category. The purchase price of the Pet Food acquisition was $1,207.5 which included (i) $700.0 in cash, subject to inventory adjustments, resulting in a payment at closing of $715.5, (ii) 5.4 shares of Post common stock, or $492.3, and (iii) immaterial working capital adjustments. The cash payment was made using cash on hand, including proceeds from the Fourth Incremental Term Loan (as defined in Note 13). Pet Food is reported in the Post Consumer Brands segment.

In connection with the Pet Food acquisition, the Company and Smucker entered into a transition services agreement (the “TSA”) pursuant to which Smucker provides certain Pet Food support services to Post for a transition period of 18 months (or up to 24 months at Post’s election) following the close of the acquisition based on the terms set forth in the TSA. Pet Food support services include, but are not limited to, certain sales, marketing, finance, information technology, procurement and supply chain services. TSA fees were $3.5 and $13.0 during the three and nine months ended June 30, 2024, respectively, and $4.0 during both the three and nine months ended June 30, 2023. TSA fees were recorded within “Selling, general and administrative expenses” in the Condensed Consolidated Statements of Operations. In accordance with the terms of the TSA, Smucker collects sales receivables from and remits payments to customers and vendors, respectively, in accordance with Smucker’s existing contractual terms. Pet Food receivables and payables are settled between Post and Smucker monthly on a net basis per the terms of the TSA. As of June 30, 2024 and September 30, 2023, the Company had recorded a net receivable due from Smucker related to the TSA of $39.1 and $35.5, respectively, which was recorded within “Receivables, net” on the Condensed Consolidated Balance Sheets.

Earnings Per Share [Abstract]

(Loss) Earnings per Share

EARNINGS PER SHARE

Basic earnings per share is based on the average number of shares of common stock outstanding during the period. Diluted earnings per share is based on the average number of shares used for the basic earnings per share calculation, adjusted for the dilutive effect of stock options, stock appreciation rights and restricted stock units using the “treasury stock” method and convertible senior notes using the “if converted” method.

Remeasurements to the redemption value of the redeemable NCI prior to the PHPC Redemption were recognized as a deemed dividend (see Note 3). The Company made an election to treat the portion of the deemed dividend that exceeded fair value as an adjustment to income available to common shareholders for basic and diluted earnings per share. In addition, dilutive net earnings was adjusted for interest expense, net of tax, related to the Company’s convertible senior notes.

The following table sets forth the computation of basic and diluted earnings per share.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Financial Instruments and Hedging

DERIVATIVE FINANCIAL INSTRUMENTS

In the ordinary course of business, the Company is exposed to commodity price risks relating to the purchases of raw materials and supplies, interest rate risks and foreign currency exchange rate risks. The Company utilizes derivative financial instruments, including (but not limited to) futures contracts, option contracts, forward contracts and swaps, to manage certain of these exposures by hedging when it is practical to do so. The Company does not hold or issue financial instruments for speculative or trading purposes.

Cash flows associated with all derivatives are reported as cash flows from operating activities in the Condensed Consolidated Statements of Cash Flows, unless the derivative contains an other-than-insignificant financing element, in which case its cash flows are reported as cash flows from financing activities.

At June 30, 2024, the Company’s derivative instruments, none of which were designated as hedging instruments under ASC Topic 815, “Derivatives and Hedging,” consisted of:

•commodity and energy futures, swaps and option contracts which relate to inputs that generally will be utilized within the next two years;

•foreign currency forward contracts (the “FX contracts”) maturing in the next 12 months that have the effect of hedging currency fluctuations between the Euro and the Pound Sterling; and

•pay-fixed, receive-variable interest rate swaps maturing in June 2033 that require monthly settlements and have the effect of hedging interest payments on debt expected to be issued but not yet priced.

During the nine months ended June 30, 2024, the Company received cash proceeds of $5.2 in connection with the termination of its interest rate swap contracts with a $400.0 notional value.

During the nine months ended June 30, 2023, the Company paid $55.1 in connection with the termination of $849.3 notional value of its rate-lock swap contracts, of which $43.5 related to the termination of rate-lock swap contracts that contained other-than-insignificant financing elements and were reported as cash flows from financing activities in the Condensed Consolidated Statements of Cash Flows. The Company also paid $2.1 in connection with the termination of $332.6 notional value of its interest rate swap option, and received cash proceeds of $6.7 in connection with the termination of its interest rate swap contract with a $200.0 notional value.

The following table presents the notional amounts of derivative instruments held.

	June 30, 2024		September 30, 2023
Commodity and energy contracts	$	200.8	$	263.9
FX contracts	$	3.7	$	3.0
Interest rate swaps	$	300.0	$	700.0

The following table presents the balance sheet location and fair value of the Company’s derivative instruments. The Company does not offset derivative assets and liabilities within the Condensed Consolidated Balance Sheets.

Fair Value Measurements

FAIR VALUE MEASUREMENTS

The following table presents the Company’s assets and liabilities measured at fair value on a recurring basis and the basis for that measurement according to the levels in the fair value hierarchy in ASC Topic 820, “Fair Value Measurement.”

	$	55.1	$	—	$	55.1	$	52.9	$	—	$	52.9

Deferred Compensation

The deferred compensation investments are primarily invested in mutual funds, and their fair value is measured using the market approach. These investments are in the same funds, or funds that employ a similar investment strategy, and are purchased in substantially the same amounts, as the participants’ selected notional investment options (excluding Post common stock equivalents), which represent the underlying liabilities to participants in the Company’s deferred compensation plans. Deferred compensation liabilities are recorded at amounts due to participants in cash, based on the fair value of participants’ selected notional investment options (excluding certain Post common stock equivalents to be distributed in shares) using the market approach.

Derivatives

The Company utilizes the income approach to measure fair value for its commodity and energy derivatives. The income approach uses pricing models that rely on market observable inputs such as yield curves and forward prices. FX contracts are valued using the spot rate less the forward rate multiplied by the notional amount. The Company’s calculation of the fair value of interest rate swaps is derived from a discounted cash flow analysis based on the terms of the contract and the interest rate curve. Refer to Note 11 for the classification of changes in fair value of derivative assets and liabilities measured at fair value on a recurring basis within the Condensed Consolidated Statements of Operations.

Equity Securities and Other Fair Value Measurements

The Company uses the market approach to measure the fair value of its equity securities, which were immaterial as of both June 30, 2024 and September 30, 2023. The Company’s financial assets and liabilities also include cash and cash equivalents, receivables and accounts payable for which the carrying value approximates fair value due to their short maturities (less than 12 months). The Company does not record its current portion of long-term debt and long-term debt at fair value on the Condensed Consolidated Balance Sheets. The fair values of any outstanding borrowings under the municipal bond and the Revolving Credit Facility (as defined in Note 13) as of June 30, 2024 and September 30, 2023 approximated their carrying values. Based on current market rates, the fair value (Level 2) of the Company’s debt, excluding any outstanding borrowings under the municipal bond and the Revolving Credit Facility, was $5,904.7 and $5,491.5 as of June 30, 2024 and September 30, 2023, respectively, which included $632.8 and $572.6 related to the Company’s convertible senior notes, respectively.

Certain assets and liabilities, including property, goodwill and other intangible assets, are measured at fair value on a non-recurring basis using Level 3 inputs.

Long-Term Debt - Senior Notes

6.25% Senior Notes

On February 20, 2024, the Company issued $1,000.0 principal value of 6.25% senior secured notes (the “6.25% senior notes”) maturing in February 2032. The 6.25% senior notes were issued at par, and the Company received $986.7 after incurring underwriting fees and other fees and expenses of $13.3, which were deferred and are being amortized to interest expense over the term of the 6.25% senior notes. Interest payments on the 6.25% senior notes are due semi-annually each August 15 and February 15, and the maturity date of the 6.25% senior notes is February 15, 2032.

The 6.25% senior notes and the related guarantees are secured by first-priority security interests, subject to permitted liens, in collateral that generally includes most of the Company’s and the subsidiary guarantors’ property except for real property and certain other excluded assets. The assets that secure the 6.25% senior notes also secure (and will continue to secure) the Credit Agreement (as defined below) on a pari passu basis.

The 6.25% senior notes are fully and unconditionally guaranteed, jointly and severally, on a senior secured basis by each of the Company’s existing and subsequently acquired or organized wholly-owned domestic subsidiaries that guarantee the Credit Agreement or certain of the Company’s other indebtedness, other than immaterial subsidiaries, certain excluded subsidiaries and subsidiaries the Company designates as unrestricted subsidiaries, which such unrestricted subsidiaries include 8th Avenue and its subsidiaries. These guarantees are subject to release in certain circumstances.

With a portion of the net proceeds received from the 6.25% senior notes issuance, borrowings under the New Revolving Credit Facility (as defined below) and cash on hand, the Company repaid the outstanding principal balance of the Fourth Incremental Term Loan (as defined below) and all accrued, unpaid interest thereon, redeemed the remainder of the outstanding 5.75% senior notes maturing in March 2027 and all accrued, unpaid interest to the redemption date and repaid the outstanding borrowings under the Old Revolving Credit Facility (as defined below) and all accrued, unpaid interest thereon. For additional information, see the “Credit Agreement,” “Fourth Incremental Term Loan” and “Repayments of Debt” sections below.

Convertible Senior Notes

On August 12, 2022, the Company issued $575.0 principal value of 2.50% convertible senior notes maturing in August 2027. The initial conversion rate of the 2.50% convertible senior notes is 9.4248 shares of the Company’s common stock per one thousand dollars principal amount of the 2.50% convertible senior notes, which represents an initial conversion price of approximately $106.10 per share of common stock. The conversion rate, and thus the conversion price, may be adjusted under certain circumstances as described in the indenture governing the 2.50% convertible senior notes (the “Convertible Notes Indenture”). The Company may settle conversions by paying or delivering, as applicable, cash, shares of its common stock or a combination of cash and shares of its common stock, at the Company’s election. If a “make-whole fundamental change” (as

defined in the Convertible Notes Indenture) occurs, then the Company must in certain circumstances increase the conversion rate for a specified period of time.

The 2.50% convertible senior notes may be converted at the holder’s option up to the second scheduled trading day immediately before the maturity date of August 15, 2027 under the following circumstances:

•during any calendar quarter (and only during such calendar quarter) if the last reported sale price per share of the Company’s common stock exceeds 130% of the conversion price for each of at least 20 trading days, whether or not consecutive, during the 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter;

•during the five consecutive business days immediately after any 10 consecutive trading day period (such 10 consecutive trading day period, the “Measurement Period”) in which the trading price per one thousand dollars principal amount of the 2.50% convertible senior notes for each trading day of the Measurement Period was less than 98% of the product of the last reported sale price per share of the Company’s common stock on such trading day and the conversion rate on such trading day;

•upon the occurrence of certain corporate events or distributions on the Company’s common stock described in the Convertible Notes Indenture;

•if the Company calls the 2.50% convertible senior notes for redemption; and

•at any time from, and including, May 15, 2027 until the close of business on the second scheduled trading day immediately before the August 15, 2027 maturity date.

If a “fundamental change” (as defined in the Convertible Notes Indenture) occurs, then, except as described in the Convertible Notes Indenture, holders of the 2.50% convertible senior notes may require the Company to repurchase their 2.50% convertible senior notes at a cash repurchase price equal to the principal amount of the 2.50% convertible senior notes to be repurchased, plus accrued and unpaid interest, if any, to, but excluding, the “fundamental change repurchase date” (as defined in the Convertible Notes Indenture).

The 2.50% convertible senior notes may be redeemed, in whole or in part (subject to the partial redemption limitation described in the Convertible Notes Indenture), at the Company’s option at any time, and from time to time, on or after August 20, 2025 and on or before the 35th scheduled trading day immediately before August 15, 2027, at a cash redemption price equal to the principal amount of the 2.50% convertible senior notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the redemption date, only if the last reported sale price per share of the Company’s common stock exceeds 130% of the conversion price on (i) each of at least 20 trading days, whether or not consecutive, during the 30 consecutive trading days ending on, and including, the trading day immediately before the date the Company sends the related redemption notice, and (ii) the trading day immediately before the date the Company sends such notice.

As of both June 30, 2024 and September 30, 2023, none of the conditions permitting holders to convert their 2.50% convertible senior notes had been satisfied, and no shares of the Company’s common stock had been issued in connection with any conversions of the 2.50% convertible senior notes.

The 2.50% convertible senior notes had no embedded features that required separate bifurcation under ASC Topic 815 as of June 30, 2024 or September 30, 2023. As such, the 2.50% convertible senior notes were recorded at the principal amount, net of unamortized issuance costs, on the Condensed Consolidated Balance Sheets as of both June 30, 2024 and September 30, 2023.

Long-Term Debt - Credit Agreement

Credit Agreement

On March 18, 2020, the Company entered into a second amended and restated credit agreement (as amended, including by Joinder Agreement No. 1, Joinder Agreement No. 2, the Third Joinder Agreement (as defined below), the Fourth Joinder Agreement (as defined below) and the Third Amendment (as defined below), as amended, restated or amended and restated, the “Credit Agreement”). Prior to the effective date of the Third Amendment, the Credit Agreement provided for a revolving credit facility in an aggregate principal amount of $750.0 (the “Old Revolving Credit Facility”), with the commitments thereunder to be made available to the Company in U.S. Dollars, Canadian Dollars, Euros and Pounds Sterling. Letters of credit are available under the Credit Agreement in an aggregate amount of up to $75.0.

On February 20, 2024, the Company entered into a third amendment to the Credit Agreement (the “Third Amendment”) by and among the Company, as borrower, certain of the Company’s subsidiaries, as guarantors, Barclays Bank PLC (“Barclays”), as administrative agent under the Credit Agreement prior to the effective date of the Third Amendment, JPMorgan Chase Bank, N.A. (“JPMorgan Chase”), as administrative agent under the Credit Agreement from and after the effective date of the Third Amendment, the institutions constituting the 2024 Revolving Credit Lenders, the L/C Issuers and the Swing Line Lender (as

each such term is defined in the Third Amendment). The Company incurred $6.6 of financing fees in connection with the Third Amendment, which were deferred and are being amortized to interest expense over the remaining term of the Credit Agreement.

The Third Amendment to the Credit Agreement (i) replaced the Old Revolving Credit Facility with a new revolving credit facility in an aggregate principal amount of $1,000.0 (the “New Revolving Credit Facility”), (ii) extended the maturity date of the New Revolving Credit Facility to February 20, 2029, provided that if on October 16, 2027 the Company’s 5.625% senior notes maturing in January 2028 have not been redeemed in full in cash or refinanced and replaced in full with notes and/or loans maturing at least 91 days after February 20, 2029, then the maturity date of the New Revolving Credit Facility will be October 16, 2027 and (iii) modified certain other terms, conditions and provisions of the Credit Agreement, including transferring the administrative agent role from Barclays to JPMorgan Chase. The term “Revolving Credit Facility” used herein generally refers to the Old Revolving Credit Facility prior to the Third Amendment and the New Revolving Credit Facility subsequent to the Third Amendment.

Borrowings in U.S. Dollars under the New Revolving Credit Facility bear interest, at the option of the Company, at an annual rate equal to either (a) the adjusted term SOFR rate (as defined in the Credit Agreement) or (b) the base rate determined by reference to the highest of (i) the prime rate, (ii) the NYFRB Rate (as defined in the Credit Agreement) plus 0.50% per annum and (iii) the one-month adjusted term SOFR rate plus 1.00% per annum, in each case plus an applicable margin, which is determined by reference to the secured net leverage ratio (as defined in the Credit Agreement), with the applicable margin for adjusted term SOFR rate loans and base rate loans being (i) 2.00% and 1.00%, respectively, if the secured net leverage ratio is greater than or equal to 3.00:1.00, (ii) 1.75% and 0.75%, respectively, if the secured net leverage ratio is less than 3.00:1.00 and greater than or equal to 1.50:1.00 or (iii) 1.50% and 0.50%, respectively, if the secured net leverage ratio is less than 1.50:1.00. Commitment fees on the daily unused amount of commitments under the Revolving Credit Facility accrue at a rate of 0.375% if the Company’s secured net leverage ratio is greater than or equal to 3.00:1.00, and accrue at a rate of 0.25% if the Company’s secured net leverage ratio is less than 3.00:1.00.

During the nine months ended June 30, 2024, the Company borrowed $645.0 and repaid $345.0 under the Revolving Credit Facility. There were no borrowings or repayments under the Revolving Credit Facility during the nine months ended June 30, 2023. As of June 30, 2024, the Revolving Credit Facility had outstanding borrowings of $300.0, outstanding letters of credit of $20.0 and an available borrowing capacity of $680.0. As of September 30, 2023, the Revolving Credit Facility had no outstanding borrowings, outstanding letters of credit of $19.7 and an available borrowing capacity of $730.3. As of June 30, 2024, the interest rate on the outstanding borrowings under the Revolving Credit Facility was 6.93%.

The Credit Agreement provides for potential incremental revolving and term facilities at the request of the Company and at the discretion of the lenders or other persons providing such incremental facilities, in each case on terms to be determined, and also permits the Company to incur other secured or unsecured debt, in all cases subject to conditions and limitations specified in the Credit Agreement.

The Credit Agreement provides for customary events of default, including material breach of representations and warranties, failure to make required payments, failure to comply with certain agreements or covenants, failure to pay or default under certain other indebtedness in excess of $125.0, certain events of bankruptcy and insolvency, inability to pay debts, the occurrence of one or more unstayed or undischarged judgments in excess of $125.0, attachments issued against all or any material part of the Company’s property, certain events under the Employee Retirement Income Security Act of 1974, a change of control (as defined in the Credit Agreement), the invalidity of any loan document and the failure of the collateral documents to create a valid and perfected first priority lien (subject to certain permitted liens). Upon the occurrence and during the continuance of an event of default, the maturity of the loans under the Credit Agreement may accelerate and the agent and lenders under the Credit Agreement may exercise other rights and remedies available at law or under the loan documents, including with respect to the collateral and guarantees of the Company’s obligations under the Credit Agreement.

On November 18, 2022, the Company entered into Joinder Agreement No. 3 (the “Third Joinder Agreement”) by and among the Company, as borrower, certain of the Company’s subsidiaries, as guarantors, J.P. Morgan Securities LLC (“J.P. Morgan”), as lender, Barclays, as administrative agent, and JPMorgan Chase, as sub-agent to the administrative agent. The Third Joinder Agreement provided for an incremental term loan (the “Third Incremental Term Loan”) of $130.0 under the Company’s Credit Agreement, which the Company borrowed in full on November 18, 2022.

On November 21, 2022, the Company and J.P. Morgan entered into an exchange agreement pursuant to which the Company transferred the remaining shares of BellRing common stock it held from its previous transactions related to the distribution of a portion of its interest in BellRing, which occurred in fiscal 2022, to J.P. Morgan to repay $99.9 in aggregate principal amount of the Third Incremental Term Loan (such exchange, the “Fiscal 2023 Debt-for-Equity Exchange”). Following the completion of the Fiscal 2023 Debt-for-Equity Exchange, the Company no longer held shares of BellRing

common stock. On November 25, 2022, the Company repaid the remaining principal balance of $30.1 of the Third Incremental Term Loan using cash on hand. For additional information, see “Repayments of Debt” below.

The Fourth Joinder Agreement provided for an incremental term loan (the “Fourth Incremental Term Loan”) of $400.0 under the Credit Agreement, which the Company borrowed in full on April 26, 2023.

On February 20, 2024, the Company repaid the outstanding principal balance of the Fourth Incremental Term Loan and all accrued, unpaid interest thereon using a portion of the net proceeds from the 6.25% senior notes issuance. For additional information, see “Repayments of Debt” below.

Pension and Other Postretirement benefits

PENSION AND OTHER POSTRETIREMENT BENEFITS

The Company maintains qualified defined benefit plans in the U.S., the U.K. and Canada for certain employees primarily within its Post Consumer Brands and Weetabix segments. Certain of the Company’s employees are eligible to participate in the Company’s postretirement benefit plans (partially subsidized retiree health and life insurance).

On February 16, 2024, the Company adopted the Post Holdings, Inc. 2024 Supplemental Executive Retirement Plan (the “SERP”), an unfunded, non-qualified defined benefit retirement plan for certain management employees of the Company, including its named executive officers, that was effective on February 19, 2024. The SERP is a supplemental program that provides a cash balance benefit to each participant. The SERP participants were credited with an opening credit, based on years of past service with the Company, and accrue ongoing benefits with a pay credit equal to a percentage of certain of the participant’s annualized compensation. The Company recorded an initial projected benefit obligation of $8.3 related to the SERP during the second quarter of fiscal 2024, which was included in “Accumulated other comprehensive loss” on the Condensed Consolidated Balance Sheets at June 30, 2024. Net periodic benefit costs related to the SERP during the three and nine months ended June 30, 2024 were immaterial.

Amounts for the Canadian plans and the SERP are included in the North America disclosures and are not disclosed separately because they do not constitute a significant portion of the combined amounts.

The following tables present the components of net periodic benefit cost (income) for the pension plans. Service cost was reported in “Cost of goods sold” and “Selling, general and administrative expenses” and all other components of net periodic benefit cost (income) were reported in “Other income, net” in the Condensed Consolidated Statements of Operations.

Segment Reporting [Abstract]

Segments

SEGMENTS

At June 30, 2024, the Company managed and reported operating results through the following four reportable segments:

•Post Consumer Brands: North American RTE cereal, pet food and peanut butter;

•Weetabix: primarily U.K. RTE cereal, muesli and protein-based shakes;

•Foodservice: primarily egg and potato products; and

•Refrigerated Retail: primarily side dish, egg, cheese and sausage products.

Due to the level of integration between the Foodservice and Refrigerated Retail segments, it is impracticable to present total assets separately for each segment. An allocation has been made between the two segments for depreciation based on inventory costing.

Amounts reported for Corporate in the table below include any amounts attributable to PHPC prior to the PHPC Redemption in the third quarter of fiscal 2023 (see Note 3).

Management evaluates each segment’s performance based on its segment profit, which for all segments is its earnings/loss before income taxes and equity method earnings/loss before impairment of property, goodwill and other intangible assets, facility closure related costs, restructuring expenses, gain/loss on assets and liabilities held for sale, gain/loss on sale of

businesses and facilities, gain on/adjustment to bargain purchase, interest expense and other unallocated corporate income and expenses.

The following tables present information about the Company’s reportable segments. In addition, the tables present net sales by product.
