Accounting Policies [Abstract]
Basis of Presentation	1. BASIS OF PRESENTATION The unaudited Condensed Consolidated Financial Statements included herein have been prepared by TreeHouse Foods, Inc. and its consolidated subsidiaries (the "Company," "TreeHouse," "we," "us," or "our"), pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC") applicable to quarterly reporting on Form 10-Q. In our opinion, these statements include all adjustments necessary for a fair presentation of the results of all interim periods reported herein. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") have been condensed or omitted as permitted by such rules and regulations. The Condensed Consolidated Financial Statements and related notes should be read in conjunction with the Consolidated Financial Statements and related notes included in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2022. Results of operations for interim periods are not necessarily indicative of annual results. Reclassification Certain prior year amounts have been reclassified to conform to the current year presentation. Specifically, Interest income has been reclassified out of Other (income) expense, net within the Condensed Consolidated Statements of Operations. Use of Estimates The preparation of our Condensed Consolidated Financial Statements in conformity with GAAP requires management to use judgment to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosures of contingent assets and liabilities at the date of the Condensed Consolidated Financial Statements, and the reported amounts of net sales and expenses during the reporting period. Actual results could differ from these estimates. Summary of Significant Accounting Policies A detailed description of the Company's significant accounting policies can be found in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2022. Segment Information The Company manages operations on a company-wide basis, thereby making determinations as to the allocation of resources as one segment. We manufacture and distribute private label food and beverages in North America. Our products are primarily shelf stable and share similar customers and distribution. The Chief Executive Officer, who has been identified as our Chief Operating Decision Maker ("CODM") allocates resources and assesses performance based upon discrete financial information at the consolidated level. We have one segment manager who reports directly to the CODM with incentive compensation based on aggregated consolidated results of the Company. The annual operating plan is prepared and approved by the CODM based on consolidated results of the Company. We operate our business with a centralized financial systems infrastructure, and we share centralized resources for sales, procurement, and general and administrative activities. The majority of our manufacturing plants each produce one food or beverage category. Refer to Note 18 for disaggregation of revenue for additional information of our principal products sold.

Restructuring and Related Activities [Abstract]
Growth, Reinvestment, and Restructuring Programs	2. GROWTH, REINVESTMENT, AND RESTRUCTURING PROGRAMS The Company’s growth, reinvestment, and restructuring activities are part of an enterprise-wide transformation to build long-term sustainable growth and improve profitability for the Company. These activities are aggregated into the following categories: (1) Strategic Growth Initiatives (expected completion in 2023) – a growth and reinvestment strategy and (2) other (collectively the "Growth, Reinvestment, and Restructuring Programs"). Below is a description of each of the Growth, Reinvestment, and Restructuring Programs: (1) Strategic Growth Initiatives In the first quarter of 2021, the Company began executing on its growth and reinvestment initiatives designed to invest in our commercial organization, adapt the supply chain to better support long-term growth opportunities, and further enable the Company to build greater depth in growth categories. These initiatives are intended to better position the Company to accelerate future revenue and earnings growth, and improve the execution of our strategy to be our customers' preferred manufacturing and distribution partner. This reinvestment will occur through 2023, and the cumulative costs incurred to date are $110.8 million. The Company currently expects the total costs will be up to $130.0 million, comprised of consulting and professional fees, employee-related costs, and investment in information technology. Consulting and professional fees are expected to include TreeHouse Management Operating System ("TMOS") initiatives at our manufacturing plants, building digital capabilities, and advancing automation and value engineering in our supply chain network. Employee-related costs primarily consist of severance, retention, and dedicated employee costs. (2) Other Other costs include restructuring costs incurred for retention, severance, organization redesign, information technology system implementation, costs to exit facilities or production, and other administrative costs. Retention includes one-time cash recognition payments that were expensed during the first quarter of 2022 as well as additional cash bonuses and stock-based compensation to drive retention through 2023. The costs by activity for the Growth, Reinvestment, and Restructuring Programs are outlined below: Three Months Ended Six Months Ended 2023 2022 2023 2022 (In millions) Strategic Growth Initiatives $ 3.4 $ 7.8 $ 10.4 $ 24.6 Other 5.5 6.1 13.8 19.4 Total $ 8.9 $ 13.9 $ 24.2 $ 44.0 As part of our growth, reinvestment, and restructuring programs, we generally incur expenses that qualify as exit and disposal costs under U.S. GAAP. These include severance and employee separation costs and other exit costs. Severance and employee separation costs primarily relate to cash severance, non-cash severance, including accelerated equity award compensation expense, pension, and other termination benefits. Other exit costs typically relate to lease and contract terminations. We also incur expenses that are an integral component of, and directly attributable to, our growth, reinvestment, and restructuring activities, which do not qualify as exit and disposal costs under U.S. GAAP. These include asset-related costs and other costs. Asset-related costs primarily relate to accelerated depreciation and certain long-lived asset impairments. Other costs primarily relate to start-up costs of new facilities, consulting and professional fees, information technology implementation, asset relocation costs, and costs to exit facilities. Below is a summary of costs by type associated with the Growth, Reinvestment, and Restructuring Programs: Three Months Ended Six Months Ended 2023 2022 2023 2022 (In millions) Employee-related $ 3.4 $ 3.5 $ 7.7 $ 19.3 Other costs 5.5 10.4 16.5 24.7 Total $ 8.9 $ 13.9 $ 24.2 $ 44.0 For the three and six months ended June 30, 2023 and 2022, employee-related costs primarily consisted of retention, severance, and dedicated project employee cost; and other costs primarily consisted of consulting services. Employee-related and other costs are recognized in Other operating (income) expense, net of the Condensed Consolidated Statements of Operations. The table below presents the exit cost liabilities related to severance and retention activity for the Growth, Reinvestment, and Restructuring Programs as of June 30, 2023: Severance Retention Total Exit Cost Liabilities (In millions) Balance as of December 31, 2022 $ 8.8 $ 4.2 $ 13.0 Expenses recognized 0.3 2.3 2.6 Cash payments (5.0) (6.2) (11.2) Balance as of June 30, 2023 $ 4.1 $ 0.3 $ 4.4

Receivables [Abstract]
Receivables Sales Program	3. RECEIVABLES SALES PROGRAM The Company has entered into agreements to sell certain trade accounts receivable to unrelated, third-party financial institutions at a discount (collectively, "the Receivables Sales Program"). The agreements can be terminated by either party with 60 days' notice. The Receivables Sales Program is used by the Company to manage liquidity in a cost-effective manner. The Company has no retained interest in the receivables sold under the Receivables Sales Program; however, under the agreements, the Company does have collection and administrative responsibilities for the sold receivables. Under the Receivables Sales Program, the maximum amount of outstanding accounts receivables sold at any time is $500.0 million. The following table includes the outstanding amount of accounts receivable sold under the Receivables Sales Program and the receivables collected from customers and not remitted to the financial institutions. June 30, 2023 December 31, 2022 (In millions) Outstanding accounts receivable sold $ 305.4 $ 347.1 Receivables collected and not remitted to financial institutions 176.9 204.5 Receivables sold under the Receivables Sales Program are derecognized from the Company's Condensed Consolidated Balance Sheet at the time of the sale and the proceeds from such sales are reflected as a component of the change in receivables in the operating activities section of the Condensed Consolidated Statements of Cash Flows. The receivables collected and not remitted to financial institutions are included in Accounts payable in the Condensed Consolidated Balance Sheets. The following table summarizes the cash flows of the Company's accounts receivables associated with the Receivables Sales Program. All amounts in the table below include continuing and discontinued operations: Six Months Ended June 30, 2023 2022 (In millions) Receivables sold $ 923.0 $ 1,105.5 Receivables collected and remitted to financial institutions (964.7) (1,036.5) The loss on sale of receivables represents the discount taken by third-party financial institutions and was $3.3 million and $0.9 million for three months ended June 30, 2023 and 2022, respectively, and $6.6 million and $1.3 million for the six months ended June 30, 2023 and 2022, respectively, and is included in Other (income) expense, net in the Condensed Consolidated Statements of Operations. The Company has not recognized any servicing assets or liabilities as of June 30, 2023 or December 31, 2022, as the fair value of the servicing arrangement as well as the fees earned were not material to the financial statements. 6.

ACQUISITIONS AND DIVESTITURE Acquisitions Acquisition of Coffee Roasting Capability On June 30, 2023, the Company completed the acquisition of the Direct Ship coffee business and its Northlake, Texas coffee facility (the "Coffee Roasting Capability") from Farmer Brothers Company, a national coffee roaster, wholesaler, equipment servicer and distributor of coffee, tea, and culinary products. The acquisition brings roasting, grinding, flavoring and blending capabilities to the Company's portfolio to complement the Company's existing single-serve pod and ready-to-drink coffee businesses. The purchase consideration consisted of approximately $92.2 million in cash, subject to customary purchase price adjustments. The acquisition was funded by borrowings from the Company’s $500.0 million Revolving Credit Facility. The Coffee Roasting Capability was accounted for under the acquisition method of accounting. The Company incurred approximately $2.1 million in acquisition-related costs during the three and six months ended June 30, 2023. These costs are included in General and administrative expense in the Condensed Consolidated Statements of Operations. The following table summarizes the preliminary purchase price allocation of the fair value of net tangible assets acquired: (In millions) Allocation of consideration to assets acquired: Inventories $ 31.5 Property, plant, and equipment, net 60.7 Total purchase price $ 92.2 Real property and personal property fair values were determined using the cost and market approaches. The purchase price allocation in the table above is preliminary and subject to the finalization of the Company’s valuation analysis. Acquisition of Seasoned Pretzel Capability On April 1, 2023, the Company completed the acquisition of a seasoned pretzel capability for a total purchase price of $14.0 million, which included the recognition of $5.4 million within Goodwill in the Condensed Consolidated Balance Sheets based on the preliminary purchase price allocation. The purchase price consisted of approximately $10.0 million in cash and a deferred payment of $4.0 million due in the third quarter of 2024. The deferred payment is recognized within Other long-term liabilities in the Condensed Consolidated Balance Sheets as of June 30, 2023. The acquisition is in line with our strategy to build category leadership, depth and capabilities to drive profitable growth. Discontinued Operations Sale of a Significant Portion of the Meal Preparation Business On October 3, 2022, the Company completed the sale of a significant portion of the Company’s Meal Preparation business (the "Business") to two entities affiliated with Investindustrial: Rushmore Investment III LLC, a Delaware limited liability company ("US Buyer") and 1373978 B.C., ULC, a British Columbia unlimited liability company ("CA Buyer" and together with US Buyer, the "Buyer"). The closing purchase price was $963.8 million, and during the second quarter of 2023, a $20.3 million adjustment to the purchase price was finalized, resulting in a final purchase price of $943.5 million. The final purchase price consisted of approximately $522.6 million in cash and approximately $420.9 million in a five-year secured Seller Promissory Note. Refer to Note 6 for additional information on the secured Seller Promissory Note. The Business consists of consumer packaged food manufacturers operating 14 manufacturing facilities in the United States, Canada, and Italy servicing primarily retail grocery customers. The Business includes 11 categories and sells center of the store grocery and main course meal items, such as pasta, pourable dressings, sauces, red sauces (salsas and pasta sauces), spoonables (mayos and dips), syrups, preserves, dry dinners (macaroni and cheese), dry blends and baking goods, and pie filling as well as pita chips. The Company entered into a Transition Services Agreement ("TSA") with the Buyer, which is designed to ensure and facilitate an orderly transfer of business operations. The services provided under the TSA include, but are not limited to, IT systems implementation, IT and financial shared services, procurement and order processing, customer service, distribution network separation, and a supply agreement. These services terminate at various times up to twenty-four months from the date of sale and certain services can be renewed with a maximum of an additional twelve-month period. Additionally, a $35.0 million credit was provided to the Buyer by TreeHouse to cover initial TSA set-up costs that otherwise would have been incurred by the Buyer ("TSA Credit"). The TSA Credit is included in the fair value of consideration transferred, and it represents deferred income for TreeHouse until the Company incurs the related TSA costs, at which point deferred income is reduced and TSA income recognized. TSA income is recognized as services are performed, and the income received under the TSA was $11.9 million for the three months ended June 30, 2023 and $25.3 million for the six months ended June 30, 2023. The TSA income is classified within Other operating (income) expense, net in the Company's Condensed Consolidated Statements of Operations. As of June 30, 2023, the deferred income balance on the TSA Credit was fully utilized with no balance remaining. The Company has reflected this transaction as a discontinued operation.

Income Taxes	9. INCOME TAXES Income taxes were recognized at effective rates of 29.1% and 27.9% for the three and six months ended June 30, 2023, respectively, compared to 14.2% for both the three and six months ended June 30, 2022. The change in the Company's effective tax rate for the three and six months ended June 30, 2023 compared to 2022 is primarily driven by the estimated amount of annual pre-tax earnings. Our effective tax rate may change from period to period based on recurring and non-recurring factors, including the jurisdictional mix of earnings, enacted tax legislation, state income taxes, settlement of tax audits, and the expiration of the statute of limitations in relation to unrecognized tax benefits. Management estimates that it is reasonably possible that the total amount of unrecognized tax benefits could decrease by as much as $0.3 million within the next 12 months, primarily as a result of the resolution of audits currently in progress and the lapsing of statutes of limitations. Approximately all of the $0.3 million could affect net income when settled. The timing of cash settlement, if any, cannot be reasonably estimated for uncertain tax benefits.

Amendment No. 6 implemented the replacement provisions for LIBOR with rates based on Term SOFR, plus a credit spread adjustment of 0.10%. The material terms and conditions under the Credit Agreement are otherwise substantially consistent with those contained in the Credit Agreement prior to Amendment No. 6. Revolving Credit Facility — As of June 30, 2023, the Company had $199.5 million drawn from its $500.0 million Revolving Credit Facility. The Company had remaining availability of $267.5 million under the Revolving Credit Facility, and there were $33.0 million in letters of credit under the Revolving Credit Facility that were issued but undrawn, which have been included as a reduction to the calculation of available credit. Interest is payable quarterly or, if earlier, at the end of the applicable interest period in arrears on any outstanding borrowings under the Revolving Credit Facility. The interest rates applicable to the Revolving Credit Facility are based upon the Company’s consolidated net leverage ratio or the Company’s Corporate Credit Rating, whichever results in lower pricing, and are determined by either (i) Term SOFR, plus a margin ranging from 1.20% to 1.70%, or (ii) a Base Rate (as defined in the Credit Agreement), plus a margin ranging from 0.20% to 0.70%. The unused fee on the Revolving Credit Facility is also based on the Company’s consolidated net leverage ratio or the Company’s Corporate Credit Rating, whichever results in lower pricing, and accrues at a rate ranging from 0.20% to 0.35%. Term Loan A — On December 1, 2017, the Company entered into a $500 million term loan and amended the loan to extend the maturity date to March 26, 2028. The interest rates applicable to Term Loan A are based upon the Company’s consolidated net leverage ratio or the Company’s Corporate Credit Rating, whichever results in lower pricing, and are determined by either (i) Term SOFR, plus a margin ranging from 1.675% to 2.175%, or (ii) a Base Rate (as defined in the Credit Agreement), plus a margin ranging from 0.675% to 1.175%. As a result of the principal prepayment of $174.8 million on Term Loan A in October 2022, principal amortization payments are no longer due on a quarterly basis, and the remaining principal balance is due at maturity. Interest is payable quarterly or, if earlier, at the end of the applicable interest period in arrears on any outstanding borrowings under Term Loan A. Term Loan A-1 — On December 1, 2017, the Company entered into a term loan and amended the loan amount to $930 million and extended the maturity date to March 26, 2026. The interest rates applicable to Term Loan A-1 are the same as those applicable to the Revolving Credit Facility (other than, for the avoidance of doubt, the unused fee). As a result of the principal prepayment of $325.2 million on Term Loan A-1 in October 2022, principal amortization payments are no longer due on a quarterly basis, and the remaining principal balance is due at maturity. Interest is payable quarterly or, if earlier, at the end of the applicable interest period in arrears on any outstanding borrowing under Term Loan A-1. 2028 Notes — On September 9, 2020, the Company completed its public offering of $500 million aggregate principal amount of the 2028 Notes.

Under the Plan, the Compensation Committee may grant awards of various types of compensation, including stock options, restricted stock, restricted stock units, performance shares, performance units, other types of stock-based awards, and other cash-based compensation. On April 27, 2023, the Plan was amended and restated to increase the number of shares available for issuance under the Plan by 5.0 million shares. The maximum number of shares authorized to be awarded under the Plan is approximately 22.5 million as of June 30, 2023.

Stock Options — Stock options granted under the Plan during 2022 have a three year vesting schedule, vest one-third on the second anniversary of the grant date and two-thirds on the third anniversary of the grant date, and expire ten years from the grant date. Stock options are generally only granted to employees and non-employee directors.

Restricted Stock Units — Employee restricted stock unit awards generally vest based on the passage of time in approximately three equal installments on each of the first three • On June 9, 2022, restricted stock unit awards were granted that vest on the passage of time on the eighteen month anniversary of the grant date. The fair value of the awards was $37.90 on approximately 62,000 units granted. • On December 29, 2021, restricted stock unit awards granted to certain executive members of management that vest on the passage of time in approximately three equal installments on each of the three six month anniversaries of the grant date. The fair value of the awards was $40.03 on approximately 51,200 units granted. Non-employee director restricted stock units generally vest on the first anniversary of the grant date. Certain non-employee directors have elected to defer receipt of their awards until either their departure from the Board of Directors or a specified date beyond the first anniversary of the grant date.

The grant date fair value of the awards is equal to the Company's closing stock price on the grant date. Performance Units — Performance unit awards are granted to certain members of management. These awards contain both service and performance conditions, and for certain executive members of management, a market condition, in each case as described below. • Performance goals are set and measured annually with one-quarter of the units eligible to accrue for each year in the three-year performance period. Accrued shares are earned at the end of each performance period but remain subject to forfeiture until the third anniversary of the grant date. Additionally, for the cumulative three-year performance period, one-quarter of the units will accrue. For both the annual and cumulative shares, the earned shares are equal to the number of units granted multiplied by a predefined percentage generally between 0% and 200%, depending on the achievement of certain operating performance measures. • For performance unit awards granted in 2021 through 2023, certain executive members of management received awards that were measured using a relative total shareholder return ("TSR") market condition over a three-year performance goal. The units will accrue, multiplied by a predefined percentage between 0% and 150% for the relative TSR measure, depending on the achievement attainment over the three-year performance period based on the Company's absolute annualized TSR relative to the annualized TSR of a Peer Group. The fair value of the portion of the awards based on relative TSR was valued using a Monte Carlo simulation model with a grant-date fair value of $50.43 on approximately 22,000 units granted in 2023 and a grant-date fair value of $26.84 on approximately 52,600 units granted in 2022. • During the second quarter of 2022, the Company made grants to certain of the Company’s named executive officers and certain other executive officers of performance-based restricted stock units (the "PBRSU Awards"). The PBRSU Awards include a relative TSR market condition over a two-year performance period beginning on the date of grant. The units will accrue, multiplied by a predefined percentage between 0% to 450% for the relative TSR measure, depending on the achievement attainment over the two-year performance period based on Company’s absolute annualized TSR relative to the annualized TSR of the S&P Food & Beverage Select Industry Index (the "Index"). The fair value of the awards was valued using a Monte Carlo simulation model with a weighted average grant-date fair value of $58.36 on approximately 239,300 units granted in 2022. These awards will be converted to stock or cash, at the discretion of the Compensation Committee, generally, on the third anniversary of the grant date with the exception of the PBRSU Awards on the second anniversary. The Company intends to settle these awards in stock and has the shares available to do so. Performance unit awards with market conditions are valued using a Monte Carlo simulation model. Expected volatility is based on the historical volatility of the Company’s stock price, average Peer Group stock price, or the total return value of the Index. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of the grant with a term equivalent to the expected term of the award. The expected term is the time period from the grant date to the end of the performance period. The weighted average assumptions used in the Monte Carlo simulations were as follows: Six Months Ended 2023 Dividend yield 0 % Risk-free rate 3.87 % Expected volatility (TreeHouse Foods, Inc.) 35.17 % Expected volatility (Peer Group) 35.04 % Expected volatility (Index) N/A Expected term (in years) 2.80 The following table summarizes the performance unit activity during the six months ended June 30, 2023: Performance Weighted (In thousands) Nonvested, at December 31, 2022 620 $ 45.23 Granted 99 47.73 Vested (98) 42.73 Forfeited (72) 42.10 Nonvested, at June 30, 2023 549 47.42 Three Months Ended Six Months Ended 2023 2022 2023 2022 (In millions) (In millions) Fair value of vested performance units $ 1.3 $ — $ 5.0 $ 2.0 Tax benefit recognized from performance units vested — — 0.4 0.2 Unrecognized compensation costs related to nonvested performance units are estimated to be approximately $11.6 million as of June 30, 2023 and are expected to be recognized over a weighted average period of 1.4 years. The fair value of the portion of the awards earned based on market conditions were valued using a Monte Carlo simulation model. For other awards, the grant date fair value is equal to the Company's closing stock price on the date of grant.

Commitments and Contingencies	16. COMMITMENTS AND CONTINGENCIES Shareholder Class Action and Related Derivative Actions The Company, as nominal defendant, and certain of its directors, officers and former directors and officers are parties to the following four shareholder derivative suits, each of which involves substantially similar claims and allegations: (i) Wells v. Reed, et al. , Case No. 2016-CH-16359 (filed Dec. 22, 2016 in the Circuit Court of Cook County, Illinois), asserting state law claims for breach of fiduciary duty, unjust enrichment and corporate waste; (ii) Lavin v. Reed, et al. , Case No. 17-cv-01014 (filed Feb. 7, 2017 in the United States District Court for the Northern District of Illinois), asserting state law claims for breach of fiduciary duty, unjust enrichment, abuse of control, gross mismanagement, and corporate waste; (iii) Bartelt v. Reed, et al. , Case No. 1:19-cv-00835 (filed Feb. 8, 2019 in the United States District Court for the Northern District of Illinois), asserting state law claims for breach of fiduciary duty, unjust enrichment, abuse of control, gross mismanagement, and corporate waste, as well as violations of Section 14 of the Securities Exchange Act of 1934; and (iv) City of Ann Arbor Employees' Retirement System v. Reed, et al. , Case No. 2019-CH-06753 (filed June 3, 2019 in the Circuit Court of Cook County, Illinois), asserting claims breach of fiduciary duty, aiding and abetting breaches of fiduciary duty and contribution and indemnification from the individual defendants for losses incurred by the Company. Essentially, all four complaints allege that TreeHouse, under the authority and control of the individual defendants: (i) made certain false and misleading statements regarding the Company's business, operations, and future prospects; and (ii) failed to disclose that (a) the Company's private label business was underperforming; (b) the Company's Flagstone Foods business was underperforming; (c) the Company's acquisition strategy was underperforming; (d) the Company had overstated its full-year 2016 guidance; and (e) TreeHouse's statements lacked reasonable basis. The complaints allege, among other things, that these actions artificially inflated the market price of TreeHouse common stock and resulted in harm to the Company, including the filing of the MPERS class action (see below). The Bartelt action also includes substantially similar allegations concerning events in 2017. Each of these cases involves allegations similar to those in an earlier-filed, resolved federal securities class action, Public Employees' Retirement Systems of Mississippi v. TreeHouse Foods, Inc., et al., Case No. 1:16-cv-10632 (" MPERS" ) (filed Nov. 16, 2016), in the United States District Court for the Northern District of Illinois brought on behalf of a class of all purchasers of TreeHouse common stock from January 20, 2016 through and including November 2, 2016. The MPERS complaint asserted claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and Rule 10b-5 promulgated thereunder and was based on essentially the same facts described above. The parties filed a stipulation of settlement to resolve the MPERS class action for a cash payment of $27.0 million (funded by D&O insurance) in exchange for dismissal with prejudice of the class claims and full releases. After briefing, preliminary approval, notice and a hearing, on November 17, 2021, the Court granted final approval of the settlement and entered a final judgment dismissing the case with prejudice on a classwide basis. Due to the similarity of the derivative complaints, Bartelt was consolidated with Lavin , and Ann Arbor was consolidated with Wells. On August 26, 2022, plaintiffs in the consolidated Wells case filed a second amended complaint, which was dismissed in its entirety with prejudice on March 15, 2023. The plaintiffs filed a notice of appeal on March 16, 2023, and they filed the record on appeal on May 25, 2023, which is being responded to pursuant to a briefing schedule set by the appellate court. On October 24, 2022, the plaintiffs’ designated an operative complaint in the Lavin case, which defendants have moved to dismiss, and was fully briefed as of May 25, 2023. Other Claims In addition, the Company is party in the ordinary course of business to certain claims, litigation, audits, and investigations. The Company will record an accrual for a loss contingency when it is probable that a loss has been incurred and the amount of the loss can be reasonably estimated. The Company believes it has established adequate accruals for liabilities that are probable and reasonably estimable that may be incurred in connection with any such currently pending or threatened matter. In the Company's opinion, the eventual resolution of such matters, either individually or in the aggregate, is not expected to have a material impact on the Company's financial position, results of operations, or cash flows. However, litigation is inherently unpredictable and resolutions or dispositions of claims or lawsuits by settlement or otherwise could have an adverse impact on our financial position, results of operations or cash flows for the reporting period in which any such resolution or disposition occurs. In February 2014, TreeHouse, along with its 100% owned subsidiaries, Bay Valley Foods, LLC and Sturm Foods, Inc., filed suit against Keurig Dr. Pepper Inc.'s wholly-owned subsidiary, Keurig Green Mountain ("KGM"), in the U.S. District Court for the Southern District of New York captioned TreeHouse Foods, Inc. et al. v. Green Mountain Coffee Roasters, Inc. et al . asserting claims under the federal antitrust laws, various state antitrust laws and unfair competition statutes, contending that KGM had monopolized alleged markets for single serve coffee brewers and single serve coffee pods. The Company is seeking monetary damages, declaratory relief, injunctive relief, and attorneys' fees. The matter remains pending, with summary judgment, motions to exclude certain expert opinions, and discovery sanctions motions fully briefed. On March 28, 2022, the Magistrate Judge issued a non-public Opinion and Order granting in part and denying in part the TreeHouse sanctions motion against KGM and denying the KGM sanctions motion against TreeHouse. KGM has appealed a portion of the Opinion and Order awarding sanctions to the Company. KGM is denying the allegations made by the Company in the litigation. The Company has not recorded any amount in its Condensed Consolidated Financial Statements as of June 30, 2023.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	17. DERIVATIVE INSTRUMENTS Interest Rate Swap Agreements - The Company manages its exposure to changes in interest rates by optimizing the use of variable-rate and fixed-rate debt and by utilizing interest rate swaps to hedge our exposure to changes in interest rates, to reduce the volatility of our financing costs, and to achieve a desired proportion of fixed versus floating-rate debt, based on current and projected market conditions. The Company has entered into long-term interest rate swap agreements with a notional value of $875.0 million as of both June 30, 2023 and December 31, 2022, to fix the interest rate base. Subsequent to June 30, 2023, SOFR will become the reference rate for the Company's interest rate swap agreements as a result of LIBOR ceasing to be a representative rate. Under the terms of the agreements, $875.0 million in variable-rate debt is swapped for a weighted average fixed interest rate base of approximately 2.91% through February 28, 2025. Commodity Contracts - Certain commodities the Company uses in the production and distribution of its products are exposed to market price risk. The Company utilizes derivative contracts to manage this risk. The majority of commodity forward contracts are not derivatives, and those that are generally qualify for the normal purchases and normal sales scope exception under the guidance for derivative instruments and hedging activities and, therefore, are not subject to its provisions. For derivative commodity contracts that do not qualify for the normal purchases and normal sales scope exception, the Company accounts for the contracts as derivatives. The Company's derivative commodity contracts may include contracts for diesel, oil, plastics, resin, and other commodity contracts that do not meet the requirements for the normal purchases and normal sales scope exception. Diesel contracts are used to manage the Company's risk associated with the underlying cost of diesel fuel used to deliver products. Contracts for oil, plastics, and resin are used to manage the Company's risk associated with the underlying commodity cost of a significant component used in packaging materials. Other commodity contracts that are derivatives that do not meet the normal purchases and normal sales scope exception are used to manage the price risk associated with raw material costs. As of June 30, 2023 and December 31, 2022, the notional value of the derivative commodity contracts outstanding was $12.5 million and $8.9 million, respectively. These commodity contracts have maturities expiring throughout 2023 and 2024 as of June 30, 2023. Total Return Swap Contract - The Company had an economic hedge program that used a total return swap contract to hedge the market risk associated with the unfunded portion of the Company's deferred compensation liability. The total return swap contract trades generally had a duration of one month and were rebalanced and re-hedged at the end of each monthly term. While the total return swap contract was treated as an economic hedge, the Company did not designate it as a hedge for accounting purposes. The total return swap contract was measured at fair value and recognized in the Condensed Consolidated Balance Sheets, with changes in value being recognized in the Condensed Consolidated Statements of Operations. At June 30, 2023, the Company had no outstanding and unsettled total return swap contracts, and at December 31, 2022, the notional value of the total return swap contract was $3.9 million. The following table identifies the fair value of each derivative instrument: June 30, 2023 December 31, 2022 (In millions) Asset derivatives Commodity contracts $ 0.4 $ — Interest rate swap agreements 30.0 27.2 $ 30.4 $ 27.2 Liability derivatives Commodity contracts $ — $ 0.3 Asset derivatives for commodity contracts are included within Prepaid expenses and other current assets and interest rate swap agreements are included within Other assets, net. Liability derivatives are included within Accrued expenses in the Condensed Consolidated Balance Sheets. The fair values of the commodity contracts, interest rate swap agreements, and the total return swap contract are determined using Level 2 inputs. Level 2 inputs are inputs other than quoted market prices that are observable for an asset or liability, either directly or indirectly. The fair values of the commodity contracts, interest rate swap agreements, and total return swap contract are based on an analysis comparing the contract rates to the market rates at the balance sheet date.

Use of Estimates	Use of Estimates The preparation of our Condensed Consolidated Financial Statements in conformity with GAAP requires management to use judgment to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosures of contingent assets and liabilities at the date of the Condensed Consolidated Financial Statements, and the reported amounts of net sales and expenses during the reporting period. Actual results could differ from these estimates.
Segment Information	Segment InformationThe Company manages operations on a company-wide basis, thereby making determinations as to the allocation of resources as one segment. We manufacture and distribute private label food and beverages in North America. Our products are primarily shelf stable and share similar customers and distribution.

We have one segment manager who reports directly to the CODM with incentive compensation based on aggregated consolidated results of the Company. The annual operating plan is prepared and approved by the CODM based on consolidated results of the Company. We operate our business with a centralized financial systems infrastructure, and we share centralized resources for sales, procurement, and general and administrative activities. The majority of our manufacturing plants each produce one food or beverage category.
