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.

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, 2021. Results of operations for interim periods are not necessarily indicative of annual results. 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.

Accounting Changes and Error Corrections [Abstract]
Recent Accounting Pronouncements	2. RECENT ACCOUNTING PRONOUNCEMENTS Adopted In March 2020, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting , which provides temporary optional guidance to ease the potential burden in accounting for reference rate reform. ASU 2020-04 was further amended in January 2021 by ASU 2021-01, Reference Rate Reform (Topic 848): Scope. This guidance provides optional expedients and exceptions for applying GAAP to transactions affected by reference rate reform if certain criteria are met. These transactions include contract modifications, hedging relationships, and the sale or transfer of debt securities classified as held-to-maturity. This guidance is effective as of March 12, 2020 through December 31, 2022 and may be applied prospectively to contract modifications made and hedging relationships entered into or evaluated on or before December 31, 2022. The Company has identified agreements that reference LIBOR, including interest rate swap agreements, accounts receivable sale agreements, and debt agreements. The new guidance has been or will be applied as these contracts are modified to reference other rates. The Company adopted this guidance during the second quarter of 2022 as a result of a modification to a receivable sale agreement. The adoption did not have a material impact on the Company's financial statements.

Restructuring and Related Activities [Abstract]
Growth, Reinvestment, and Restructuring Programs	3. 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 which primarily reside in our Snacking & Beverages segment. 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 $84.6 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 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, information technology system implementation, costs to exit facilities, and other administrative costs. Retention includes one-time cash recognition payments that were expensed ratably from the fourth quarter of 2021 to 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 2022 2021 2022 2021 (In millions) Strategic Growth Initiatives $ 8.8 $ 14.5 $ 26.8 $ 30.6 Other 6.8 7.7 20.9 11.2 Total $ 15.6 $ 22.2 $ 47.7 $ 41.8 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. Expenses associated with these programs are recorded in Other operating expense, net in the Condensed Consolidated Statements of Operations. The Company does not allocate costs associated with Growth, Reinvestment, and Restructuring Programs to reportable segments when evaluating the performance of its segments. As a result, costs associated with Growth, Reinvestment, and Restructuring Programs are not presented by reportable segment. Refer to Note 16 for additional information. Below is a summary of costs by type associated with the Growth, Reinvestment, and Restructuring Programs: Three Months Ended Six Months Ended 2022 2021 2022 2021 (In millions) Employee-related 4.2 7.1 $ 20.8 $ 12.0 Other costs 11.4 15.1 26.9 29.8 Total $ 15.6 $ 22.2 $ 47.7 $ 41.8 For the three and six months ended June 30, 2022 and 2021, 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 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, 2022: Severance Retention Total Exit Cost Liabilities (In millions) Balance as of December 31, 2021 $ 3.9 $ 9.7 $ 13.6 Expenses recognized 7.4 11.5 18.9 Cash payments (4.8) (15.4) (20.2) Balance as of June 30, 2022 $ 6.5 $ 5.8 $ 12.3

Receivables [Abstract]
Receivables Sales Program	4. 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, 2022 December 31, 2021 (In millions) Outstanding accounts receivable sold $ 426.3 $ 357.3 Receivables collected and not remitted to financial institutions 241.8 205.0 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: Six Months Ended June 30, 2022 2021 (In millions) Receivables sold $ 1,105.5 $ 781.9 Receivables collected and remitted to financial institutions (1,036.5) (829.6) The loss on sale of receivables represents the discount taken by third-party financial institutions and was $1.4 million and $0.6 million for the three months ended June 30, 2022 and 2021, respectively, and $2.0 million and $1.1 million for the six months ended June 30, 2022 and 2021, respectively, and is included in Other income, net in the Condensed Consolidated Statements of Operations. The Company has not recognized any servicing assets or liabilities as of June 30, 2022 or December 31, 2021, as the fair value of the servicing arrangement as well as the fees earned were not material to the financial statements.

Divestiture	6. DIVESTITURE Discontinued Operations Ready-to-eat Cereal On June 1, 2021, the Company simultaneously entered into a definitive agreement and completed the sale of its Ready-to-eat ("RTE") Cereal business to Post Holdings, Inc. ("Post") for a base purchase price of $85.0 million, subject to customary purchase price adjustments, resulting in cash proceeds at closing of $88.0 million. The Company classified the proceeds within Net cash provided by investing activities - discontinued operations, and a pre-tax gain was recognized on the transaction upon closing of $18.4 million as a component of Net income from discontinued operations in the Condensed Consolidated Statements of Operations. The sale of this business was part of the Company's portfolio optimization strategy. RTE Cereal operated as two manufacturing plants located in Lancaster, Ohio and Sparks, Nevada. The Company entered into a Transition Services Agreement ("TSA") with Post, which is designed to ensure and facilitate an orderly transfer of business operations. The services provided under the TSA terminate at various times up to twelve months from the date of sale and certain services were renewed with a maximum of an additional six-month period expected to end in the fourth quarter of 2022. The income received under the TSA was not material for the three and six months ended June 30, 2022 or 2021 and is primarily classified within General and administrative expenses or Cost of sales in the Company's Condensed Consolidated Statements of Operations depending on the functions being supported by the Company. The Company has reflected the RTE Cereal business (through the date of sale) as a discontinued operation for all periods presented. Unless otherwise noted, amounts and disclosures throughout these Notes to Condensed Consolidated Financial Statements relate to the Company's continuing operations. Results of discontinued operations are as follows: Three Months Ended Six Months Ended 2022 2021 2022 2021 (In millions) (In millions) Net sales $ (0.3) $ 30.9 $ (0.6) $ 78.4 Cost of sales (0.6) 27.7 (0.6) 69.1 Selling, general, administrative and other operating expenses 0.1 3.2 — 7.4 Gain on sale of business — (18.4) — (18.4) Operating income from discontinued operations 0.2 18.4 — 20.3 Interest and other expense — 0.3 — 0.7 Income tax (benefit) expense (1.0) 4.5 (1.0) 4.9 Net income from discontinued operations $ 1.2 $ 13.6 $ 1.0 $ 14.7

Income Tax Disclosure [Abstract]
Income Taxes	8. INCOME TAXES Income taxes were recognized at effective rates of 8.9% and 5.1% for the three and six months ended June 30, 2022, respectively, compared to 21.2% and 25.0% for the three and six months ended June 30, 2021, respectively. The change in the Company's effective tax rate for the three months ended June 30, 2022 compared to 2021 is primarily driven by the estimated amount of annual pre-tax earnings, a change in the income tax benefit from the release of tax reserves, and withholding taxes accrued in 2022. The change in the Company's effective tax rate for the six months ended June 30, 2022 compared to 2021 is primarily driven by the estimated amount of annual pre-tax earnings, a change in the income tax benefit from the release of tax reserves, and a change in the tax deductible stock-based compensation. 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 $1.5 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 $0.4 million of the $1.5 million could affect net income when settled. The timing of cash settlement, if any, cannot be reasonably estimated for uncertain tax benefits.

Stock-Based Compensation	11. STOCK-BASED COMPENSATION The Board of Directors adopted, and the Company's stockholders approved, the "TreeHouse Foods, Inc. Equity and Incentive Plan" (the "Plan"). 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. The maximum number of shares authorized to be awarded under the Plan is approximately 17.5 million.

Stock Options — The following table summarizes stock option activity during the six months ended June 30, 2022. Stock options granted under the plan 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.

The weighted average grant date fair value of options granted in 2022 was $15.62. Stock options are valued using the Black-Scholes option pricing model. Expected volatility is based on the historical volatility of the Company’s stock price. The risk-free rate for periods within the contractual life of the stock options is based on the U.S. Treasury yield curve in effect at the time of the grant. We based our expected term on the simplified method as described under the SEC Staff Accounting Bulletin No. 107. The weighted average assumptions used to calculate the value of the stock option awards granted are presented as follows: Six Months Ended 2022 Dividend yield 0 % Risk-free rate 2.93 % Expected volatility 38.54 % Expected term (in years) 6.33 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. Director restricted stock units generally vest on the first anniversary of the grant date. Certain 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 following table summarizes the restricted stock unit activity during the six months ended June 30, 2022: Employee Weighted Director Weighted (In thousands) (In thousands) Nonvested, at December 31, 2021 660 $ 48.88 50 $ 48.15 Granted 664 31.75 51 31.25 Vested (254) 50.81 (30) 48.59 Forfeited (157) 41.06 — — Nonvested, at June 30, 2022 913 37.23 71 35.88 Vested and deferred, at June 30, 2022 20 47.50 Three Months Ended Six Months Ended 2022 2021 2022 2021 (In millions) (In millions) Fair value of vested restricted stock units $ 1.7 $ 3.6 $ 9.3 $ 20.0 Tax benefit recognized from vested restricted stock units 0.3 0.9 1.5 3.2 Unrecognized compensation costs related to nonvested restricted stock units are approximately $30.6 million as of June 30, 2022 and will be recognized over a weighted average period of 2.1 years. 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. • For awards granted in years prior to 2020, for each year of the three-year performance period, one-third of the units will accrue, multiplied by a predefined percentage generally between 0% and 200%, depending on the achievement of certain operating performance measures. Accrued shares are not earned until the end of the full three-year performance period. • For performance unit awards granted in 2020 through 2022, 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. • In 2022 and 2021, certain executive members of management received awards that were measured using a relative total shareholder return ("TSR") market condition over a three-year performance period instead of a cumulative 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 $26.84 on approximately 52,600 units granted in 2022 and a grant-date fair value of $59.16 on approximately 23,200 units granted in 2021. • 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 2022 2021 Dividend yield 0 % 0 % Risk-free rate 2.36 % 0.30 % Expected volatility (TreeHouse Foods, Inc.) 36.84 % 35.65 % Expected volatility (Peer Group) 36.64 % 37.72 % Expected volatility (Index) 16.30 % N/A Expected term (in years) 2.14 2.75 The following table summarizes the performance unit activity during the six months ended June 30, 2022: Performance Weighted (In thousands) Nonvested, at December 31, 2021 480 $ 54.21 Granted 429 45.75 Vested (63) 64.55 Forfeited (191) 54.29 Nonvested, at June 30, 2022 655 44.98 Three Months Ended Six Months Ended 2022 2021 2022 2021 (In millions) (In millions) Fair value of vested performance units $ — $ — $ 2.0 $ 5.6 Tax benefit recognized from performance units vested — (0.1) 0.2 0.2 Unrecognized compensation costs related to nonvested performance units are estimated to be approximately $19.6 million as of June 30, 2022 and are expected to be recognized over a weighted average period of 1.8 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	14. 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 , Ann Arbor was consolidated with Wells. Plaintiffs in the consolidated Wells case filed an amended, consolidated complaint on February 28, 2022. Defendants moved to dismiss the amended, consolidated Wells complaint, and on July 25, 2022 the Court dismissed the amended, consolidated Wells complaint without prejudice. The consolidated Lavin case remains stayed through August 15, 2022 pending the ruling on dispositive motions in the Wells case. The Company has an accrual for a $27.0 million liability and a corresponding insurance receivable within Accrued expenses and Prepaid expenses and other current assets, respectively, in the Condensed Consolidated Balance Sheets as of June 30, 2022. Employment Related Claims On October 20, 2015, the first of a number of class actions were filed in California state court, which were consolidated under the caption Negrete v. Ralcorp Holdings, Inc., et al . (the " Negrete Action") in the U.S. District Court for the Central District of California, in which plaintiffs challenged wage and hour practices at three former Company manufacturing facilities in California. On February 7, 2022, the court granted final approval of the settlement to resolve the Negrete Action which included a payment by the Company of $9.4 million in exchange for the release of claims against the defendants and for the dismissal of the matter with prejudice. The payment was completed by the Company in the first quarter of 2022 and settled the Company's accrued liability of $9.0 million. 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, 2022.

The Company has entered into long-term interest rate swap agreements to lock into a fixed LIBOR interest rate base that have a notional value of $875.0 million as of both June 30, 2022 and December 31, 2021. 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% from 2021 through 2025. Foreign Currency Contracts - Due to the Company's foreign operations, it is exposed to foreign currency risk. The Company enters into foreign currency contracts to manage the risk associated with foreign currency cash flows. This includes, but is not limited to, using foreign currency contracts to establish a fixed foreign currency exchange rate for the net cash flow requirements for purchases of inventory, sales of finished goods, and future settlement of foreign-denominated assets and liabilities. As of June 30, 2022 and December 31, 2021, the notional value of the foreign currency contracts outstanding was $3.8 million and $5.5 million, respectively. These foreign currency contracts have maturities expiring throughout 2022 and 2023 as of June 30, 2022. 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, natural gas, electricity, 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. Contracts for natural gas and electricity are used to manage the Company's risk associated with the utility costs of its manufacturing facilities, and 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, 2022 and December 31, 2021, the notional value of the commodity contracts outstanding was $31.5 million and $58.8 million, respectively. These commodity contracts have maturities expiring throughout 2022 and 2023 as of June 30, 2022. Total Return Swap Contract - The Company has an economic hedge program that uses 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 have a duration of one month and are rebalanced and re-hedged at the end of each monthly term. The total return swap contract is 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. As of June 30, 2022 and December 31, 2021, the notional value of the total return swap contract was $4.5 million and $7.0 million, respectively. The following table identifies the fair value of each derivative instrument: June 30, 2022 December 31, 2021 (In millions) Asset derivatives Commodity contracts $ 14.5 $ 3.9 Interest rate swap agreements 1.0 — $ 15.5 $ 3.9 Liability derivatives Commodity contracts $ 1.5 $ 0.9 Foreign currency contracts 0.1 0.2 Interest rate swap agreements — 51.2 $ 1.6 $ 52.3 Asset derivatives are included within Prepaid expenses and other current assets and liability derivatives are included within Accrued expenses in the Condensed Consolidated Balance Sheets. The fair values of the commodity contracts, foreign currency 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, foreign currency 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.

Segment Reporting [Abstract]
Segment Information	16. SEGMENT INFORMATION The Company manages operations on a company-wide basis, thereby making determinations as to the allocation of resources in total rather than on a segment-level basis. The Company has designated reportable segments based on how management views its business. The Company does not segregate assets between segments for internal reporting. Therefore, asset-related information has not been presented. The two reportable segments, as presented below, are consistent with the manner in which the Company reports its results to the Chief Executive Officer, who has been identified as our Chief Operating Decision Maker. The principal products that comprise each segment are as follows: Meal Preparation – Our Meal Preparation segment sells aseptic cheese & pudding; baking and mix powders; hot cereals; jams, preserves, and jellies; liquid and powdered non-dairy creamer; macaroni and cheese; mayonnaise; Mexican, barbeque, and other sauces; pasta; pickles and related products; powdered soups and gravies; refrigerated and shelf stable dressings and sauces; refrigerated dough; single serve hot beverages; skillet dinners; and table and flavored syrups. Snacking & Beverages – Our Snacking & Beverages segment sells bars; broths; candy; cookies; crackers; in-store bakery products; pita chips; powdered drinks; pretzels; ready-to-drink coffee; retail griddle waffles, pancakes, and French toast; specialty teas; and sweeteners. The Company evaluates the performance of its segments based on net sales dollars and direct operating income. Direct operating income is defined as gross profit less freight out, sales commissions, and direct selling, general, and administrative expenses. The amounts in the following tables are obtained from reports used by senior management and do not include income taxes. Other expenses not allocated include unallocated selling, general, and administrative expenses, unallocated costs of sales, and unallocated corporate expenses (amortization expense, other operating expense, and asset impairment). The accounting policies of the Company's segments are the same as those described in the summary of significant accounting policies set forth in Note 1 to the Consolidated Financial Statements contained in our Annual Report on Form 10-K for the year ended December 31, 2021. Financial information relating to the Company's reportable segments on a continuing operations basis is as follows: Three Months Ended Six Months Ended 2022 2021 2022 2021 (In millions) (In millions) Net sales to external customers: Meal Preparation $ 765.9 $ 647.6 $ 1,494.0 $ 1,326.1 Snacking & Beverages 431.7 355.6 844.6 734.4 Total $ 1,197.6 $ 1,003.2 $ 2,338.6 $ 2,060.5 Direct operating income: Meal Preparation $ 56.0 $ 65.2 $ 115.8 $ 145.7 Snacking & Beverages 38.8 36.9 60.9 78.6 Total 94.8 102.1 176.7 224.3 Unallocated selling, general, and administrative expenses (80.3) (59.9) (151.9) (128.9) Unallocated cost of sales (2.5) 4.7 (4.0) 0.6 Unallocated corporate expense and other (1) (33.7) (42.8) (83.2) (80.9) Operating (loss) income (21.7) 4.1 (62.4) 15.1 Other (expense) income (11.9) (10.7) 27.2 (21.5) Loss before income taxes $ (33.6) $ (6.6) $ (35.2) $ (6.4) (1) Includes charges related to growth, reinvestment, and restructuring programs and other costs managed at corporate.

Accounting Changes and Error Corrections [Abstract]
Recently Issued Accounting Pronouncements	Adopted In March 2020, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting , which provides temporary optional guidance to ease the potential burden in accounting for reference rate reform. ASU 2020-04 was further amended in January 2021 by ASU 2021-01, Reference Rate Reform (Topic 848): Scope. This guidance provides optional expedients and exceptions for applying GAAP to transactions affected by reference rate reform if certain criteria are met. These transactions include contract modifications, hedging relationships, and the sale or transfer of debt securities classified as held-to-maturity. This guidance is effective as of March 12, 2020 through December 31, 2022 and may be applied prospectively to contract modifications made and hedging relationships entered into or evaluated on or before December 31, 2022. The Company has identified agreements that reference LIBOR, including interest rate swap agreements, accounts receivable sale agreements, and debt agreements. The new guidance has been or will be applied as these contracts are modified to reference other rates. The Company adopted this guidance during the second quarter of 2022 as a result of a modification to a receivable sale agreement. The adoption did not have a material impact on the Company's financial statements.
