Our purpose is to make high quality food and beverages affordable to all.

	MISSION Create value as our customers’ preferred manufacturing and distribution partner, providing thought leadership, superior innovation and a relentless focus on execution

Proxy Statement Summary

Performance Highlights

Over the last several years, our strategic progress to evolve from a decentralized holding company to a more efficient and more integrated operator, along with our two-division structure - Meal Preparation and Snacking & Beverages - has laid the foundation for positioning TreeHouse for the future, and has also been critically important in enabling us to navigate the challenges posed by the macro environment. Our challenges in 2021 included impacts related to:

•Inflation across commodities, transportation, and wages continuing to accelerate;

•Industry-wide supply chain disruption, including a constrained manufacturing labor market and impacts from the COVID-19 pandemic, impacting our network and ability to service all the customers' orders received; and

•Other macro factors, such as government stimulus, and branded promotional activity enabling consumers to alter their purchasing behavior in the first half of the year and trade up to branded products. In the second half of the year, as government stimulus began to expire and inflation escalated, we saw demand strengthen across our portfolio, with more orders than we could fulfill.

Our teams worked diligently to address these issues by executing multiple rounds of pricing actions to recover inflation over the cycle, pivoting our labor strategy to attract and retain our manufacturing workforce, securing additional transportation and supply, and collaborating with our customers to better plan for and serve their needs. While the macro environment has driven the costs to fulfill our customers' orders higher and impacted our near-term profitability, we believe that investment in the customer is the right long-term decision for the Company and one that will, over time, further strengthen our customer relationships and translate into improved financial performance. We remain committed to building a company that will generate long-term, sustainable growth and create stockholder value.

In November 2021, the Board of Directors approved a plan to explore strategic alternatives, including a possible sale of the Company or a transaction to allow the Company to focus on its higher growth Snacking & Beverages business by divesting a significant portion of its Meal Preparation business. The determination followed the Company's ongoing, Board-led strategic review which began earlier in 2021. In March 2022, after conducting a thorough and comprehensive process to market the Company for sale, the Board determined that the focus of its ongoing strategic review will be to continue reshaping TreeHouse by building leadership and depth around a focused group of its categories in its higher growth Snacking & Beverages business. The Company will continue to explore potential divestiture transactions, including the sale of portions of the Meal Preparation business, either in a single transaction or in a series of transactions. The Board unanimously determined that it was not the right time to pursue a sale of the whole Company, however, the Board remains open to all alternatives to maximize shareholder value. There can be no assurance that the exploration of strategic alternatives will result in a transaction or other strategic changes or outcomes.

Key Financial Highlights Include:

•Net sales from continuing operations of $4,327.6 million in 2021, compared to $4,349.7 million in 2020, a decrease of 0.5%;

•GAAP diluted (loss) earnings per share from continuing operations of $(0.48) in 2021, compared to $0.87 in 2020;

•Adjusted diluted EPS of $1.19 in 2021 was impacted by a number of macro headwinds including inflation, labor availability and supply chain disruption, and weaker private label consumption. This compared to adjusted diluted EPS from continuing operations of $2.73 in 2020;

•Cash provided by operating activities from continuing operations of $332.1 million in 2021 compared to $403.6 million in 2020; and

•Free cash flow from continuing operations was $216.2 million in 2021 compared to $297.9 million in 2020.

Stockholder Engagement

Here at TreeHouse, we greatly appreciate the insights and perspectives that our stockholders offer. We maintain a robust practice and cadence for our executive leadership team to engage with our stockholders. It is our belief that strong corporate governance should include regular and constructive engagement with portfolio managers and investment teams. We are committed to delivering long-term stockholder value, clearly communicating our financial goals, and holding our management team accountable for the results.

Ongoing communication with our stockholders allows our management team to better understand the issues that are important to our institutional stockholders, have a healthy dialogue, and gain useful feedback. At the quarterly meetings of the Board of Directors, management provides an update from Investor Relations to keep the Board informed of investor feedback. Additionally, from time to time the Board of Directors will engage directly with stockholders to further understand their perspectives and contemplate their feedback as it pertains to strategic decisions.

In 2021, we actively conducted outreach, engaging both existing stockholders (representing approximately 64% of our outstanding shares of Common Stock) and prospective investors to discuss items such as the Company’s strategy, progress, governance, compensation, and sustainability. Our approach to engagement with the investor community in 2021 was as follows:

•Hosted the quarterly earnings conference call webcasts and posted presentations to the Company's website

•Met with investors through industry conferences, non-deal roadshows and one-on-one meetings utilizing virtual engagement platforms

•Presented and engaged with investors at The Consumer Analyst Group of New York Annual Conference, The Barclays Global Consumer Conference, and The Bank of America Leveraged Finance Conference

•Engaged stockholders through perception study, written correspondence and one-on-one meetings

•Held several conversations between large stockholders and the Board of Directors to further understand their perspective and feedback

•Conducted outreach and solicited feedback from stockholders on our pay and governance policies

•Published annual communications to stockholders: Annual Report, Proxy Statement, and 10-K

•Conducted the Annual Meeting of Stockholders

•Published quarterly 10-Q communications to stockholders

10 2022 Proxy Statement

Proxy Statement Summary

Pay for Performance Alignment

Our compensation approach is based on sound design principles that allow us to responsibly reward our executives in a labor climate where we need to attract and retain talent capable of executing our strategic business transformation. Our Compensation Committee is committed to aligning the interests of our executives with those of our stockholders by working to ensure actual compensation received by our executives is aligned to the business results of the Company. Our programs are designed to focus executives on achievement of our long-term business objectives and creation of stockholder value. This is achieved by maintaining a high level of "at-risk" incentive pay, the majority of which is linked to the achievement of long-term business results and delivered in equity - further aligning interests to those of our stockholders. Our performance goals require significant effort to obtain target awards and we hold our executives accountable to those stretch objectives. As we continue our business transformation, we believe our Compensation Committee needs the ability to ensure we are not only rewarding for current results, but also for actions that successfully set the Company up for future growth.

Following a year that tested our ability to continue delivering to our customers through extraordinary service demands while protecting the health and safety of our employees, 2021 presented a new set of challenges, including an extraordinary macro environment that further impacted our financial performance. As noted above, this included industry-wide supply chain disruption, continued accelerated inflation across commodities, transportation and labor, and other macro economic factors such as government stimulus temporarily impacting demand signals. Predicting these impacts when setting our incentive goals was challenging and while our teams worked diligently to address these issues by executing multiple rounds of pricing actions to recover inflation over the cycle, pivoting our labor strategy to attract and retain our manufacturing workforce, securing additional transportation and supply, and collaborating with our customers to better plan for and serve their needs, we still fell short of our 2021 operating plan.

Our Board, and specifically the Compensation Committee, recognize that many of our accomplishments took place against the challenging backdrop of this macro environment and carefully evaluated the balancing of the interests of our stockholders, customers and employees in making decisions related to our 2021 incentive plans. We did not adjust any performance goals for our annual or long-term performance plans and the Compensation Committee did not exercise any discretion with respect to plan payouts. Consistent with our philosophy of aligning actual pay with Company performance and our need to balance a series of business impacts, this resulted in:

•A zero payout for our Annual Incentive Plan ("AIP") including no payout for our NEOs. We did not achieve our operating net income funding gate and delivered 2021 results below minimum performance for both revenue and operating net income under the plan.

•A payout of 57% of target for our 2019-2021 Long-term Performance Plan reflecting our results relative to the average 3-year goal set at the beginning of the performance period.

Over the past five years, our annual incentive payouts as a percent of target have varied widely from year-to-year based on our operating performance. Further specifics on the AIP can be found in "Compensation Discussion and Analysis" ("CD&A") of this Proxy Statement.

Environmental, Social and Governance (ESG)

At TreeHouse Foods, we are committed to expanding environmental stewardship, stakeholder value creation, and thoughtful governance in everything we do. This commitment to Environmental, Social, and Governance (ESG) integration across the organization is fundamental in meeting the expectations of our employees, investors, customers, and consumers. Our ability to better identify and address risk, create value, and improve our environmental and social performance is key in delivering long-term success.

In 2021, we continued to build upon our sustainability strategy and efforts by actively pursuing our ESG goals for 2025 and by ensuring we stay true to our values that incorporate our ESG commitments:

Own It

As a manufacturer of food and beverage products, we have a responsibility towards our customers and employees to own our impact and focus on reducing it. Our company is committed to not only improving our own environmental and social impact, but also supporting our stakeholders in improving their own efforts as well. Our employees are key to helping us to find ways to identify opportunities that contribute to our ESG efforts.

Commit to Excellence

We believe in setting high standards and then working to achieve them, and our ESG goals are an example of our commitment to build a company focused on achieving environmental and social change throughout our enterprise. Progress on ESG issues begins with the engagement and passion of our people, and we commit to ensuring our people’s safety in every aspect of our operations as we work towards our shared goals.

Be Agile

We believe it is imperative that we have an aligned and embedded view of our ESG strategy and performance so that we can adjust and respond to our stakeholder needs and expectations quickly and effectively. Long-term commitment requires a collective sense of purpose and shared vision for the future, and we are committed to the persistent and consistent action required to bring our ESG strategy to life.

Speak Up

The world is rapidly changing, and our employees and our customers expect more from us than ever before. We know, as one of the largest private label manufacturers in our industry, and as the employer of thousands of individuals, it is our responsibility to speak up and address injustice when we see it, and we expect our employees to do the same. ESG efforts often address risks to the business, and we encourage our stakeholders to help us identify risks and address them before they turn into problems. Our employees and partners are critical to our success and we view them as essential partners in our work to reduce risks to our business and create value to our customers.

Better Together

We know we cannot do this alone. It is only with the support and collaboration of our employees, vendors, and customers that we will be able to deliver real change. We have created a cross-functional approach to engage employees at all levels of our business to help us advance our ESG efforts.

Proxy Statement Summary

2021 ESG Report - Highlights

In November 2021, we published our second annual ESG Report that details our efforts in integrating ESG throughout the organization, our 2020 performance against our ESG goals, and our overall progress in ESG focus areas most relevant to our business and to our stakeholders. To meet emerging expectations of investors and other stakeholders, our report also includes disclosures aligned with standards and recommendations from the Sustainable Accounting Standards Board (SASB) and the Task Force for Climate-related Financial Disclosures (TCFD). These disclosures are included within our 2021 ESG Report which we have made available through the "ESG" link within "Reports and Disclosures" on our website at www.treehousefoods.com. Our ESG goals are aspirational and may change. Statements regarding our goals are not guarantees or promises that they will be met.

•In 2020, our total water withdraw was 1.66 million gallons, a 12% year-over-year reduction in total water withdrawn.

•In 2020, 23 plants achieved a landfill diversion rate of over 90%. This was accomplished primarily through plant-led

improvements to reduce the amount of waste sent to landfills.

•In 2021, we launched our Sustainable Packaging Assessment focused on engaging our suppliers and customers to continue to find ways to reduce our plastics and packaging footprint.

Social

•In 2020, we achieved an 80% response rate in our first annual employee engagement survey.

•In 2020, we introduced Diversity, Equity, and Inclusion (DEI) training for our TreeHouse Leadership Community and implemented the first Employee Resource Group (ERG) to support working parents and caregivers. The DEI Council has continued this work following its formation in 2021.

•Our responsible sourcing efforts include focusing on third-party standards and certifications that reflect our ESG and

ingredient quality expectations such as Roundtable on Sustainable Palm Oil (RSPO), Fair Trade, Rain Forest Alliance (RFA) and Certified Organic, where appropriate.

•Over 96% of the suppliers we directly sourced our ingredients from were certified to a Global Food Safety Initiative (GFSI)-recognized food safety certification program.

Governance

•50% of our board composition represents women and/or racially and ethnically underrepresented leadership. We are committed to having a Board that reflects diverse perspectives, including those based on gender, ethnicity, skills, and experience.

•The Board receives quarterly updates on ESG performance and per its charter, the Nominating & Governance Committee

reviews the ESG program in depth annually as part of its ESG strategy oversight responsibility.

•In 2021, we added a DEI key performance metric to our executive compensation program to strengthen our commitment to building a diverse and inclusive workforce and culture.

Proxy Statement Summary

Human Capital Management

Employee engagement is one of the key drivers of performance at TreeHouse. We have conducted our first employee engagement survey and laid out the framework for our employee engagement plan development, including targeted pulse check surveys to help us identify opportunities for improvement and gauge employee interest in potential programs. Feedback from our initial engagement survey has informed three focus areas for continuing to drive our employee engagement success:

Strategy

Aligning, executing, and communicating on our corporate and ESG strategies so that employees at all levels understand and can actively participate in our strategic direction.

Collaboration

Help our teams work together to focus on common goals and initiatives and build trust within and across our teams.

Career Growth

Support our talent by building and strengthening core business and leadership capabilities through development programs and resources.

Diversity, Equity, and Inclusion

We have built the foundation for developing a DEI Strategic Roadmap, a multi-year enterprise-wide approach to accelerating our DEI journey. In order to support the development of the Roadmap and ensure sustained DEI efforts and practices, we formed a Diversity, Equity, and Inclusion Council in 2021. Initial plans for the Council include expanding the ERG options based on employee interest, rolling out DEI training to broader audiences across TreeHouse, and partnering with our recruitment function to design tools for establishing diverse candidate slates.

Climate Change and Energy

TreeHouse recognizes that reducing its energy intensity and carbon footprint is its responsibility as a manufacturer, as well as an opportunity to achieve efficiencies and cost savings. We are implementing plans based on the energy and emissions initiatives rolled out in 2020 to help meet our climate and energy goals by 2025. We are committed to reducing our greenhouse gas emissions intensity (Scope 1 and 2 emissions) by 5% by 2025 against a 2020 baseline, as well as working with our suppliers to complete a Scope 3 Assessment and set a reduction goal by the end of 2025.

We are also aware that the nature of our business exposes us to potential physical climate-related impacts and risks associated with the transition to a low carbon economy. Our Enterprise Risk Management (ERM) model, in combination with our ESG Strategy, guides and informs our overall risk management approach to climate-related physical, market, and regulatory risks. Looking forward, we will work to incorporate climate change risks into our Business Continuity Plan by 2025.

The Company’s Amended and Restated Certificate of Incorporation (the "Charter") and Amended and Restated By-laws (the "By-laws") provide that the Board of Directors ("Board") shall be composed of not less than three nor more than 15 directors divided into three classes to be determined by the Board, and that each director shall be elected for a term of three years with the term of one class expiring each year. We believe that obtaining a three-year commitment from our directors assists us in retaining highly qualified directors who have experience and familiarity with our business and the markets in which we operate. The Board believes that such long-term institutional knowledge benefits TreeHouse and enables the Board to better consider and provide long-term strategic planning.

Following the resignation of John P. Gainor, Jr. and Ashley Buchanan on April 30, 2022, our Board consists of 10 directors. At the Annual Meeting, you will elect a total of three directors named in this Proxy Statement, subject to the provisions of the Company’s By-laws, to hold office until the Annual Meeting of Stockholders in 2025 and until their successors are duly elected and qualified. Unless you instruct otherwise, the shares represented by your proxy will be voted FOR the election of Mark R. Hunter, Linda K. Massman, and Jason J. Tyler, the nominees described below. The affirmative vote of a majority of the votes cast is required to elect each director. In other words, the number of votes “for” a director must exceed the number of votes “against” a director in order to elect such director. For information regarding our resignation policy, see “Summary of the Annual Meeting — Resignation Policy” in this Proxy Statement.

Mr. Hunter, Ms. Massman, and Mr. Tyler have each agreed to be nominated and to serve as a director if elected. However, if any nominee at the time of his or her election is unable or unwilling to serve, or is otherwise unavailable for election, the Board may vote to reduce the size of the Board or may nominate another person to serve as director and the person(s) to whom you have given your proxy will be able to use his or her discretion to vote on your behalf for such other person.

The Board of Directors

Nomination of Directors

The Board is responsible for approving candidates for Board membership and has delegated the process of screening and recruiting potential director nominees to the Nominating and Corporate Governance Committee in consultation with the Chair of the Board and Chief Executive Officer.

The Nominating and Corporate Governance Committee seeks candidates who have a reputation for integrity, honesty, and adherence to high ethical standards and who have demonstrated business acumen, experience, and an ability to exercise sound judgment in matters that relate to the current and long-term objectives of the Company. The Nominating and Corporate Governance Committee considers diversity as one of a number of factors in identifying nominees for director. The Committee views diversity broadly to include diversity of experience, skills, and viewpoint as well as traditional diversity concepts such as race and gender. When the Nominating and Corporate Governance Committee reviews a candidate for Board membership, the Nominating and Corporate Governance Committee looks specifically at the candidate’s background and qualifications in light of the needs of the Board and the Company at that time, given the then-current composition of the Board. The aim is to assemble a Board that provides a significant breadth of experience, knowledge, and abilities that assist the Board in fulfilling its responsibilities.

The current members of the Board, including our nominees, hold or have held senior executive positions in large, complex organizations and have operating experience that meets this objective. In these positions, they have gained experience in core management skills, such as strategic and financial planning, public company financial reporting, compliance, risk management, and leadership development. Many of our directors also have experience serving on boards of directors and board committees of other public companies and have an understanding of corporate governance practices and trends. We consider the members of our Board to have a diverse set of business and personal experiences, backgrounds and expertise.

Identifying New Directors

The Nominating and Corporate Governance Committee receives suggestions for new directors from a number of sources, including current Board members and stockholders (see “Stockholder Proposals for 2023 Annual Meeting of Stockholders” for further details). It also may, in its discretion, employ a third-party search firm to assist in identifying candidates for director. Once a potential director candidate has been identified, including through the recommendation of a stockholder in accordance with the procedures set forth in our By-laws, the Nominating and Corporate Governance Committee evaluates the candidate according to the factors described above.

Corporate Governance

Over the past few years, we have refocused our efforts on Board refreshment. The Board believes the fresh perspectives brought by new directors are critical to a forward-looking and strategic Board while retaining those who have a deep understanding of TreeHouse’s business provided by longer-serving directors.

The Board is committed to having a Board that reflects diverse perspectives, including those based on gender, ethnicity, skills, experience at policy-making levels in areas that are relevant to the Company’s activities, and functional, geographic or cultural background.

The Board does not believe it should establish term limits. Term limits could result in the loss of directors who have been able to develop, over a period of time, increasing insight into the Company and its operations and an institutional memory that benefits the entire membership of the Board as well as management. However, the Board does believe that a mandatory retirement age for directors is appropriate and has adopted the policy that an individual may not stand for election or reelection to the Board if such individual (i) has reached 75 years of age or (ii) would reach 75 years of age during such individual’s term as a director if elected or re-elected; provided, however, from time to time the Board may re-nominate a director for additional terms if the Board determines that due to such director’s unique capabilities and/or special circumstances, such re-nomination is in the best interest of the Company.

The Board’s Role and Responsibilities

The Board’s Role in Risk Oversight

Management is responsible for day-to-day risk assessment and mitigation activities, and our Company’s Board is responsible for risk oversight, focusing on our Company’s overall risk management strategy, our Company’s degree of tolerance for risk, and the steps management is taking to manage our Company’s risks. While the Board as a whole maintains the ultimate oversight responsibility for risk management, the committees of the Board can be assigned responsibility for risk management oversight of specific areas, as set forth below:

Full Board Together with the Board’s standing committees, the Board regularly reviews material risks identified by management and the Board. The Board and its committees regularly review the actions by management to address material risk.		Audit Committee As part of its responsibilities as set forth in its charter, the Audit Committee discusses with management the Company’s policies and guidelines to govern the process by which risk assessment and risk management are undertaken by management, including guidelines and policies to identify the Company’s major financial risk exposures, and the steps management has taken to monitor and control such exposures. The Audit Committee also performs an oversight role with respect to financial and compliance risks.		Senior Management Senior management tracks and evaluates risks across all aspects of the Company's business operations.
		Compensation Committee The Compensation Committee considers risk in connection with its design of compensation policies and practices for our employees and executives.
		Nominating and Corporate Governance Committee The Nominating and Corporate Governance Committee annually reviews the Company’s Corporate Governance Guidelines and their implementation.

Cybersecurity

Information technology and data security, particularly cybersecurity, is a focus area for our Board. Despite our best efforts, we are at risk from data breaches and system disruptions. Although to date we are unaware of any material data breach or system disruption, including a cyber-attack, we cannot provide any assurances that such events and impacts will not be material in the future. Our Board is engaged in the oversight of management's cybersecurity risk program through quarterly cybersecurity updates given by members of management during Audit Committee meetings. The effectiveness of our cybersecurity risk program is measured through key performance indicators, which are reported to the Board along with our key cybersecurity plans. The Company carries cybersecurity insurance in the event of a cybersecurity breach.

As part of the ongoing information security awareness training, and as established in the Code of Ethics, employees are routinely educated regarding the Company's position on data privacy; protecting confidential, proprietary information, and intellectual property; and safeguarding technology systems. Employees are provided ongoing mandatory training to coincide with emerging and macro cyber risk factors, and those unique to our business and work environment. The training results are reviewed by the Board and management as part of their ongoing cybersecurity risk assessment.

The Nominating and Corporate Governance Committee oversees an annual review by the Board regarding succession planning matters. Included in the review are the position of Chief Executive Officer & President, Chief Financial Officer, and other executive officer positions in the Company. Management succession discussions also include a review of transitional leadership plans in the event of an unplanned vacancy in these roles.

Corporate Governance Guidelines and Code of Ethics

Board Structure

Board Leadership

The Board has determined that the appropriate leadership structure for the Board is to separate the roles of Chair and Chief Executive Officer, and to appoint an independent director to serve as Chair of the Board. We believe this structure represents the appropriate allocation of roles and responsibilities at this time. Accordingly, the Board appointed Ms. Sardini to serve as independent Chair of the Board on April 29, 2021.

In her capacity as Chair of the Board, Ms. Sardini’s duties entail:

•Approving the Board meeting agendas;

•Determining the frequency and length of Board meetings;

•Conducting and presiding at executive sessions of the Board;

•Serving as a liaison to and acting as a regular communication channel between the non-management members of the Board and the Chief Executive Officer of the Company; and

•Consulting with the Chief Executive Officer about the concerns of the Board.

We do not have a formal policy that requires the Chief Executive Officer and Chair of the Board roles to be separated, and the Board, in its discretion, may subsequently decide to change our leadership structure. However, in the event the Chair of the Board is not an independent director, the Corporate Governance Guidelines provide that the Board will elect a Lead Independent Director to, among other things, preside at executive sessions of the Board and act as a liaison between the non-management members of the Board and the Chief Executive Officer.

Director Independence

Except as may otherwise be permitted by NYSE rules, our Corporate Governance Guidelines provide that a majority of the members of the Board shall be independent directors under applicable law and NYSE listing standards. To be considered independent: (1) a director must be independent as determined under Section 303A.02(b) of the New York Stock Exchange Listed Company Manual; and (2) in the Board’s judgment (based on a review of all relevant facts and circumstances and taking into consideration all applicable laws, regulations and stock exchange listing requirements), the director does not have a material relationship with the Company (either directly or as a partner, stockholder or officer of an organization that has a relationship with the Company).

Based on its review, the Board determined that none of our non-management directors has a material relationship with the Company and that all of them are independent. Specifically, (i) current directors Messrs. Hunter, Ostfeld, Scalzo, Tuchman, and Tyler and Mses. Massman, Rahman, Sardini, and Spence have no direct or indirect material relationships with management, and that they satisfy the NYSE’s independence guidelines and are independent; (ii) former directors Mr. Gainor and Mr. Buchanan, who served as directors until April 30, 2022, and Mr. Smith, who served as a director until July 29, 2021, had no direct or indirect material relationships with management, and satisfied the NYSE’s independence guidelines and were independent during the time they served as a director; and (iii) that Mr. Oakland is not independent. Mr. Oakland is the Chief Executive Officer and President of the Company.

All members of our Audit, Compensation, and Nominating and Corporate Governance Committees are independent directors and our Compensation Committee members meet the enhanced independence requirements for Compensation Committee members under the NYSE’s listing standards. The Board has determined that all of the members of our Audit Committee also satisfy the SEC independence requirement, which provides that they may not accept directly or indirectly any consulting, advisory or other compensatory fee from the Company or any of its subsidiaries other than their directors’ compensation.

Our Board’s standards for director independence are available in our Corporate Governance Guidelines.

The non-management directors of the Company meet regularly (at least quarterly) in executive sessions of the Board without management present.

Board Self-Assessments

Our directors undergo an annual Board self-evaluation to determine whether the Board and its committees are functioning effectively. As part of the self-evaluation process, directors provide feedback evaluating Board and committee effectiveness on multiple criteria. The Nominating and Corporate Governance Committee receives comments from all directors and reports annually to the Board with an assessment of the Board’s performance. Each committee also conducts a self-evaluation and reports its assessment of effectiveness to the Board. The assessments are discussed with the full Board each year.

Director Orientation and Continuing Education

The Board and the Company’s management conduct a mandatory orientation program for new directors. The orientation program includes presentations by management to familiarize new directors with the Company’s strategic plans, its significant financial accounting, and risk management issues, its compliance programs, its Code of Ethics, its principal officers, its internal and independent auditors, its General Counsel, and outside legal advisors. In addition, the orientation program includes a review of the Company’s expectations of its directors in terms of time and effort, a review of the director’s fiduciary duties and visits to Company headquarters, and, to the extent practical, certain of the Company’s significant facilities.

Each director is encouraged to be involved in continuing director education on an ongoing basis to enable him or her to better perform his or her duties and to recognize and deal appropriately with issues that arise.

Each year, we require our directors and executive officers to complete a questionnaire, among other things, to identify such related party relationships and transactions. We also require that directors and executive officers notify our General Counsel of any changes during the course of the year to the information provided in the annual questionnaire as soon as possible and we gather information regarding possible related party transactions throughout the year. As required under SEC rules, transactions involving the Company that exceed $120,000 and that a related party has a direct or indirect material interest in are disclosed in our Proxy Statement.

Pursuant to Section 14A of the Exchange Act, we are seeking the advisory approval by our stockholders of the Company’s executive compensation program and practices as disclosed in this Proxy Statement. As approved by its stockholders at the 2017 Annual Meeting of Stockholders, consistent with the Board’s recommendation, the Company is submitting this proposal for a non-binding vote on an annual basis. Thus, the next advisory vote to approve the Company’s executive compensation program after this meeting will be held at the Company’s 2023 annual meeting.

In deciding how to vote on this proposal, the Board urges our stockholders to read the "Compensation Discussion and Analysis", which describes in detail our executive compensation philosophy and programs. In particular, you should consider the following factors, which are more fully discussed in the "Compensation Discussion and Analysis": •We seek input from our stockholders and consider their views when designing our executive compensation programs; •Our programs are designed to pay for performance with a majority of our NEOs' total compensation based on the performance of the Company and a significant portion linked to the achievement of long-term financial goals; •Our executive compensation program incorporates practices that ensure ongoing good governance, including a "claw-back" policy, anti-hedging and anti-pledging policies, stock ownership guidelines and no excise tax gross-ups. The affirmative vote of a majority of the votes cast is required to approve this Proposal 2.
	The Board recommends that stockholders vote “FOR” approval of the advisory resolution set forth above. Proxies solicited by the Board will be voted for the approval of the advisory resolution set forth above unless stockholders specify a contrary vote.

Executive Overview

Our Strategic Review and 2021 Results

2021 was a challenging financial year for our organization as we worked diligently to address a macro environment with unprecedented inflation and supply chain disruptions. Our focus for the year was execution of multiple rounds of pricing actions to cover inflation, pivoting our labor strategy to more effectively attract and retain our manufacturing workforce, actions to secure additional transportation and supply and closely collaborating with our customers to better plan for and service their needs.

These factors created significant downward pressure on 2021 financial results. Net sales from continuing operations was generally flat from prior year, but profitability and cash flow were below prior year due to significant unanticipated incremental costs and labor challenges driven by the various macro environment factors. Additionally, in November 2021, the Board of Directors approved a plan to explore strategic alternatives.

In response to these developments, we did not modify any of our incentive plan targets, but throughout 2021, continued to evaluate our executive compensation program with the goal of balancing the need to align pay and performance with that of attracting and retaining leaders critical to guiding the organization through this transformative, challenging period.

•Provide cash retention to approximately 100 key employees payable at the earlier of consummation of a transaction or the end of 2022, and

•Grant strategic review retention awards(1), consisting of cash (the “Cash Award”) and restricted stock units (“RSU Award”) to select members of our executive team including NEOs Messrs. Kelley, Craig, Fleming and Ms. Waterman as follows:

(2)    Mr. Craig forfeited all strategic review retention awards (cash & RSUs) at the time of his voluntary separation to accept another role; further supporting the need for this additional retention for other key leaders.

The Cash Awards were paid on March 15, 2022. The RSU Awards will vest in three equal installments on each of the six, twelve and eighteen month anniversaries following the grant date of December 29, 2021, subject to continued employment through each such vesting date.

Approximately 93% of our votes cast at the 2021 Annual Meeting approved the NEO compensation program described in our 2021 Proxy Statement. The Committee values the opinions of our stockholders and continues to consider their perspective when structuring our executive compensation program.

Enhanced Stockholder Engagement

The perspective of stockholders is a critical input considered by the Committee for structuring our executive compensation programs and we remain committed to consistently soliciting this input through ongoing dialogue with our investors. As is our standard practice, the Committee reviewed the results of our 2021 say on pay vote and the specific feedback we received from investors and proxy advisors regarding our executive compensation program. This feedback was one of many factors taken into consideration when making the changes to our executive compensation program detailed below. We continue to listen carefully to input from our investors as we focus on aligning our pay programs with our evolving business strategy which includes addressing some legacy practices.

In an effort to enhance our stockholder engagement efforts related to our executive compensation program, in early 2021, we contacted top investors holding approximately 50% of our outstanding shares in the aggregate to solicit feedback on our pay and governance practices. Four of these stockholders, representing approximately 28% of our outstanding shares, accepted our invitation to engage and the Chair of our Compensation Committee led the engagement conversations with those four stockholders. Additionally, throughout 2021, in conjunction with our ongoing stockholder outreach efforts noted above, we also continued to routinely seek input on our executive compensation program.

Changes to 2021 Executive Compensation Program

Based on feedback from our stockholders and the continuing transformation of our business, we made several changes to our executive compensation program in 2021. These changes were made to ensure our executive's compensation continues to evolve along with our business and effectively rewards our executives to drive value for our stockholders.

In 2021, we strengthened the linkage between stockholder value creation and incentive payouts, as follows:

•In our Annual Incentive Plan

◦We eliminated the personal performance component for our NEOs and other senior leaders so they are incented exclusively on financial metrics and strategic objectives

◦We enhanced our strategic objectives to include ESG goals

◦We Introduced a "gating feature" that requires minimum levels of profitability to fund any incentive pool

•In our Long-term Incentive Plan

◦We introduced relative Total Shareholder Return ("r-TSR") with a three-year performance period compared against an industry index for our executive team, including our NEOs

Our CEO's Pay Program

This section outlines Mr. Oakland's compensation since joining TreeHouse as CEO in March 2018. Additional detail for each component of pay, including incentive design information, can be found in the section titled "Our Performance-Based Compensation Structure" below.

2018 - 2021 CEO Compensation

Mr. Oakland joined the Company as CEO on March 26, 2018. The Company increased Mr. Oakland's target total compensation by 6% in 2019 with 86% of his compensation in "at risk" pay and 68% of that increase in the target value of long-term equity awards, which demonstrates the Committee's commitment to ensuring alignment between Mr. Oakland's compensation and the interests of our stockholders. Mr. Oakland received no adjustment to his target total compensation in 2020 or 2021.

Executive Compensation

CEO Pay Alignment to Performance

Since Mr. Oakland joined in 2018, the Company has delivered 8% cumulative total shareholder return as of December 31, 2021. Since Mr. Oakland's compensation is structured with a large percentage "at risk" and delivered in equity, the compensation he can realize ("Realizable") and that which he actually receives ("Realized") has fluctuated over time based on return to our shareholders - demonstrating alignment between pay and performance. No pay actually received is due to the sale of shares as Mr. Oakland has not sold any TreeHouse shares since he joined the Company.

Mr. Oakland's target compensation includes his fixed base salary, target annual incentive, and target value of long-term incentives for the applicable year. Realizable pay includes his fixed base salary, actual annual incentive earned in the performance year, and the value as of December 31, 2021, of equity granted since hire (reflecting actual or projected performance as applicable). For purposes of this chart, Mr. Oakland's PSU awards reflect current performance projections, which values the remaining three tranches of 2021 PSU award included at target. Realized pay includes his fixed base salary, actual annual incentive earned in the performance year, and the actual value of equity that vested in that year. New hire awards are not included.

Base Salary

As the only fixed compensation element in our program, base salaries are reviewed annually, but are only adjusted by the Committee as needed. Increases are not guaranteed or automatic. For 2021, the Committee chose to not increase base salaries for any of the NEOs, except for Mr. Kelley, whose salary was increased to better align with our competitive market in his first full year as CFO and Ms. Waterman who received a 5.8% increase in December 2021 when her role was expanded to include oversight for the Human Resources organization.

Annual Incentives

For 2021, our AIP was redesigned to increase the weighting of financial performance and strategic objectives, and to eliminate the personal performance metric from the plan for all Vice Presidents, including our NEOs. Additionally, the Committee introduced an Operating Net Income gating feature that requires the achievement of at least 90% funding for operating net income in order to fund the other plan components. These changes better ensure that payouts are aligned with value creation for our stockholders, while mitigating the need for the Committee to exercise discretion on AIP payouts.

In 2021, our NEO's AIP awards were tied to financial performance, weighted 80%, and strategic objectives, weighted 20%. Our financial performance is measured by (i) revenue, weighted at 35%, providing focus on top-line growth and (ii) operating net income, weighted at 45%, providing focus on profitability. Our strategic objectives, weighted at 20%, were based on the enterprise-wide strategic goals of gross margin improvement, diversity and employee engagement.

Targets for these financial metrics are set consistent with our commitments in our Annual Operating Plan (AOP) as approved by our Board. These goals are set to be sufficiently ambitious to ensure alignment between pay and performance and also provide the opportunity to earn higher payouts in years where performance exceeds expectations. The 2021 AIP goals were set higher than both 2020 AIP goals and 2020 AIP actual results.

2022 Proxy Statement 47

Executive Compensation

The total AIP payout opportunity ranges from 0% for performance below minimum up to 200% for performance at or exceeding maximum. As shown below, for 2021, the Company did not achieve threshold performance levels for revenue or operating net income and thus, no payouts were earned.

The table below shows the 2021 funding for the 80% of the incentive that was based on financial performance.

Performance Measure	Minimum ($)	Target ($)	Maximum ($)	2021 Result ($)	% Achievement (%)	Payout % (%)	Weighted Payout % (%)
Operating Net Income(1)	155.4M	168.9M	182.5M	66.9M	39.6	—	—
Revenue(2)	4.40B	4.52B	4.71B	4.3B	95.7	—	—

(1)    Defined as the amount of adjusted after tax net income that underlies Adjusted Earnings Per Share as disclosed each quarter in the Company's earnings report.

(2)    Defined as net sales from continuing operations as reported in Company's 10-K filed on February 15, 2022.

If the Operating Net Income gating threshold for funding was met (which it was not as described above), then the other 20% of the AIP award payout opportunity would be based on the following enterprise-wide strategic objectives:

•Gross Margin Improvement: Gross profit of 19.8% needed to achieve a 100% payout

•Employee Engagement and Diversity: Company improvement for both objectives was measured using a scorecard approach detailed below —

No Funding	Funding from 50%-80% of Target	Target Funding
Overall Employee Engagement Index score declines from baseline AND THS fails to implement a strategy to drive improved organizational diversity	Overall Employee Engagement Index score is maintained at baseline OR THS implements a strategy to drive improved organizational diversity	Overall Employee Engagement Index score improves from baseline AND THS implements a strategy to drive improved organizational diversity

For 2021, although we made progress against our ESG strategic objectives, due to our financial performance (detailed above), the strategic objectives portion of the AIP was not funded this component was determined to result in a at 0% payout.

Over the past five years, our annual incentive payouts as a percent of target have varied widely from year-to-year based on our operating performance; demonstrating alignment between our pay and performance

Long-Term Incentives

The long-term incentive program is designed to ensure our NEOs focus on long-term growth, profitability, and value creation. Long- term incentives are the largest portion of our NEO's compensation and are delivered 100% in equity. This ensures that our executives are rewarded largely based on long-term stock performance in the interest of our key stakeholders, which include our stockholders and employees. Each NEO's long-term incentive award value is determined annually by the Compensation Committee based on an analysis of our competitive market along with an assessment of individual performance.

2021 Long-Term Incentive Program

The long-term incentive program provides for awards of performance stock units ("PSUs") and restricted Stock Units ("RSUs"), each accounting for 50% of the total long-term incentive grant. By delivering our long-term awards 100% in equity, our program directly aligns with stockholder interests by linking pay outcomes to long-term performance. Providing a portion of our long-term incentives in time vested RSUs has been and continues to be critical to provide some degree of stability as we move through our organizational transformation and navigate a challenging macro environment. Awards are granted annually typically in March and we do not structure the timing of our equity awards to precede or coincide with the disclosure of material non-public information.

2021 Award Mix: In March 2021, the Compensation Committee approved a target long-term equity award for each NEO, expressed as a percentage of base salary, and approved the equity award mix for the NEOs of 50% RSUs and 50% PSUs, with the PSUs earned based on the achievement of operating net income, pre-financing free cash flow and relative total shareholder return ("r-TSR"). Operating net income and pre-financing free cash flow have goals set and measured annually and r-TSR is measured over a three-year performance period. In 2021, we did not make changes to 2020 long term incentive targets for any of our NEOs.

Grant Year	Performance Measurement Year
	2021 (25%)	2022 (25%)	2023 (25%)
2021	Operating Net Income and Pre-Financing Free Cash Flow	Operating Net Income and Pre-Financing Free Cash Flow	Operating Net Income and Pre-Financing Free Cash Flow
	3-Year Relative TSR (25%)

PSUs Relative TSR Performance Measurement: The Committee added a three year r-TSR performance metric to our PSU program in 2021 to further enhance alignment between our executives and stockholders. Awards are earned based on our TSR percentile rank against the Russell 3000 Packaged Foods & Meats Index over the 2021-2023 measurement period based on the following payout scale:

	Payout (% Target)	Percentile Rank
Maximum	150%	100th Percentile
Target	100%	50th Percentile
Minimum	50%	25th Percentile

Payouts are capped at 100% of target if TSR is negative.

PSUs Operating Net Income & Pre-Financing Free Cash Flow Performance Measurement: Operating net income and pre-financing free cash flow goals are measured over the 2021-2023 performance period. Beginning in 2020, and retained for the 2021 awards, the Company revised the design of its PSU awards, to set and measure these financial goals annually, but require that earned awards do not vest until the end of the full three year performance period, subject to continued employment with TreeHouse. This design allows the Committee to effectively reward progress toward achievement of our long-term strategy at a time when long-term goal setting is particularly challenging given the transformational state of our business and external market factors, including COVID-19 and inflation, which create unpredictable business volatility. Award payouts range from zero to two times the target amount, based upon performance achievement levels. Earned awards are typically settled in stock, however the Committee has discretion to settle the awards in either stock or cash following the conclusion of the three-year performance period.

Restricted Stock Units: The RSUs vest annually in three equal tranches, subject to the grantee’s continued employment with the Company from the grant date through each vesting date.

The 2019-2021 performance stock unit awards were earned based on the higher of average or cumulative performance of operating net income and pre-financing free cash flow over the 2019-2021 three year performance period with each performance measure weighted 50%.

The payout opportunity for these awards ranged from 0% - 200% with the units earned for each performance period determined as follows:

If the Percentage of Target Earned is 100% or greater	((Percentage of Target Earned – 100%)*5) + 100%
If the Percentage of Target is less than 100% but greater or equal to 80%	((Percentage of Target Earned – 80%)*2.5) + 50%
If the Percentage of Target is less than 80%	No Performance Units are earned

Performance over the three year period resulted in a 57% payout, earned based on the average 3 year performance over the period.

Long-Term Performance Award Payouts as % of Target
Five Year History

Settlement of 2019 Accelerated Performance Awards

In order to retain and align key executives with the Company's revised business strategy, in early 2019, the Company granted a limited number of accelerated performance units to certain key employees. These grants were eligible to vest to the extent that certain (i) key customer service goals were attained in each of calendar years 2019 (up to 1/3 of the units), 2020 (up to 1/6 of the units), and 2021 (up to 1/6 of the units), and (ii) organic revenue growth goals were attained in each of calendar years 2020 and 2021 (up to 1/6 of the units per year). If the organic revenue growth goal for calendar year 2020 was not achieved, but the cumulative organic revenue growth for calendar years 2020 and 2021 equaled or exceeded the calendar year 2020 and 2021 goals in the aggregate, both related tranches of each award would have been eligible to vest. There is no payout range for the award, so the units associated with each performance criteria could be either fully earned at 100% or fully forfeited.

In 2021, the Committee determined that the performance criteria were not achieved, which resulted in the forfeiture of these awards without any payout in 2021.

Executive Perquisites

We do not provide our NEOs with excessive perquisites, but do provide the benefits and perquisites detailed in the table below to enhance our ability to attract and retain talented executives and keep them healthy and focused on the Company's business.

Executive Compensation Decision Making Process

Role of Our Independent Advisor

For 2021, the Committee engaged Pay Governance LLC ("Pay Governance") as the Committee’s independent executive compensation advisor. Pay Governance does not provide services to the Company other than the services provided directly to the Committee. Pay Governance advises the Committee on the Company's directors and executive compensation strategies and program design as well as providing regulatory and market trend updates. Pay Governance carries out competitive reviews as directed by the Committee and provides input on specific compensation recommendations for our CEO and other members of the executive leadership team, some of whom are NEOs.

Pay Governance participates in Committee meetings, including regular discussions with the Committee, without management present, to ensure impartiality on certain decisions. In early 2021, the Committee reviewed the independence of Pay Governance in light of SEC rules and NYSE listing standards regarding compensation consultants and has concluded that Pay Governance was independent and that its work for the Compensation Committee does not raise any conflict of interest.

Evaluating and Planning Executive Compensation

The Committee routinely works with its compensation advisor to evaluate the competitiveness of our executive compensation programs. When setting annual compensation for our NEOs, the Committee balances the current state of the business with future goals of the Company. The Committee, with assistance from their independent advisor, considers peer company pay practices for comparable positions, NEO experience, tenure, scope of responsibility and performance, internal pay alignment, and succession planning.

The primary data used to evaluate our competitiveness is a publicly-traded company peer group of similarly sized companies in our industry with whom we believe we compete for executive talent (the “Peer Group”). We supplement this information with general industry survey data to benchmark those roles for whom proxy data is unavailable and to ensure we are also evaluating pay practices within the general industry competitive market. For 2021, the Committee considered both Peer Group and general industry survey data in evaluating the competitiveness of our executive compensation program.

In 2020, due to ongoing business transformation and divestitures, Pay Governance recommended a revised Peer Group to be used to evaluate the competitiveness of our executive compensation program. The private-label food manufacturing business is largely dominated by non-publicly traded companies, making the construct of an appropriate Peer Group more complex. Pay Governance utilized a detailed screening process, as illustrated below, that considered a variety of factors, such as industry, revenue, market cap and enterprise value, and business model. Each screening factor was used to further refine our group of companies to the resulting final 17 company Peer Group approved by the Committee.

Stock Ownership Requirements

To ensure strong alignment of our senior management with the interests of our stockholders, the Company maintains stock ownership guidelines for our senior executives, including each of our NEOs. The Committee reviews compliance with the ownership guidelines annually.

Our guidelines provide that members of our executive team must meet, within five years of becoming subject to the applicable ownership requirement, specified stock ownership levels equal to a multiple of their base salary. If the ownership requirement is not satisfied within the 5-year period, the executive is required to hold at least 50% of net shares until the stock ownership guidelines are met. Shares of stock owned outright or through a trust and unvested time-based restricted stock units count towards fulfillment of the guidelines. In the Committee's last review, it was determined that all NEOs had met their stock ownership requirements or are within the five-year achievement period. The required stock ownership levels are as follows:

Position	Required Stock Ownership Level
Chief Executive Officer	6x Base Salary
Executive Vice Presidents	3x Base Salary
Senior Vice President (executive team only)	2x Base Salary

Employment Agreements and Executive Severance Plan

We have entered into an employment agreement with Mr. Oakland (and with Mr. O’Neill, which was in effect prior to his departure). All other NEOs are covered under the TreeHouse Foods, Inc. Executive Severance Plan. These arrangements provide for payments and other benefits if the NEO’s employment terminates for a qualifying reason, including termination without “Cause” or for “Good Reason,” (as defined in the agreements). The arrangements also provide for benefits upon a qualifying termination following a “Change in Control” (as defined in the agreements) of the Company. Additional information regarding the agreements, including a definition of key terms and a quantification of benefits that would have been received by each NEO had a termination of employment occurred on the last business day of the fiscal year ended December 31, 2021, is found under the heading “Potential Payments Upon Termination or Change in Control.”

We believe these severance programs are an important part of our overall compensation arrangements for our NEOs. We also believe these arrangements will help to secure the continued employment and dedication of our NEOs prior to or following a change in control, without concern for their own continued employment. We believe it is in the best interest of our stockholders to have a plan in place that will allow management to pursue all alternatives for the Company without undue concern for their own financial security. These agreements are important as a recruitment and retention device, as most of the companies with which we compete for executive talent have similar agreements in place for their senior employees.

Under our Executive Severance Plan, in the event of a change in control, no severance payments are made or equity awards vested without both the change in control and termination - a double trigger construct. More details of the benefits to which our NEOs are entitled upon certain terminations of employment are summarized below under the heading, “Potential Payments Upon Termination or Change in Control.”

Employment Agreement with Steve Oakland

In connection with his appointment as President and Chief Executive Officer of the Company, and as previously disclosed, the Company entered into an employment agreement with Mr. Oakland, effective as of March 2, 2018.

The agreement currently renews each March on an annual basis unless either party gives the other party 90 days’ advance written notice of intent not to renew the then current term. Mr. Oakland is entitled to an annual base salary of no less than $1,000,000 and is eligible to receive annual incentive bonuses with a target amount equal to 130% of his base salary. Mr. Oakland is also eligible for annual awards under the Company’s long-term incentive plan, with each annual award approximately equal in aggregate value to $5,000,000. Mr. Oakland is eligible to participate in the employee benefits plans and programs generally available to officers of the Company and is eligible for an annual perquisite allowance of $25,000.

Mr. Oakland is subject to a nondisclosure covenant regarding confidential information, a twelve-month post-termination non-competition covenant and a twelve-month post-termination non-solicitation covenant. Mr. Oakland's employment agreement does not provide for any “gross up” payment from the Company in the event that Mr. Oakland would incur excise taxes under Section 4999 of the tax code (the “Code”).

In connection with his departure, the Company entered into transition agreements with Mr. O’Neill in June of 2021. Pursuant to these agreements, Mr. O’Neill received separation benefits consistent with a termination without cause under his employment agreement. He also agreed to provide limited advisory services to the Company for a period of time following his termination date. During this period, Mr. O’Neill is acting as an advisor for the ongoing Keurig Green Mountain litigation in exchange for an annual fee of $200,000 and a contingent fee based on a percentage of any final settlement for the litigation, which will range from 0.8% to 1.2% of the gross proceeds. The agreements also include a customary release of claims and reaffirmation of Mr. O’Neill’s restrictive covenant obligations to the Company.

Recoupment of Compensation Upon Restatement of Financial Results

We have a recoupment (“clawback”) policy effective for all cash and equity based incentive awards granted on or after January 1, 2014. The policy applies to all our employees at or above the Vice President level (which includes our NEOs) and is administered by our Compensation Committee. Under the policy, if the Company is required to restate its financial statements due to material noncompliance with its financial reporting requirements under securities laws and a covered individual is determined to have knowingly and willfully engaged in conduct which was a material factor in such restatement, the Compensation Committee may seek reimbursement of any excess compensation from any cash and equity based awards granted to such covered individual in the preceding 3 years (or preceding 12 months in the case of recoupment of proceeds from the sale of shares pursuant to stock options, restricted stock units or performance share units).

Tax Impact on Executive Compensation Program Design

The tax impact of various elements of our total compensation program has been an important, but not the sole, consideration in its design. Section 162(m) of the Internal Revenue Code limits the deductibility of certain items of compensation paid to the CEO and certain other highly compensated executive officers (together the "covered officers") to $1,000,000 annually. While the Compensation Committee generally considers this limit when determining compensation, the Compensation Committee reserves the right to provide for compensation to executive officers that may not be deductible pursuant to Section 162(m).

Compensation Risk Assessment

In partnership with the independent advisor to the Committee, we annually assess our employee compensation programs to determine whether our programs appropriately balance risk/reward in our executive compensation programs and do not incentivize our employees, including the NEOs, to take excessive risks. This risk assessment is annually reviewed with the Committee and the outcome of this year's review was the determination that we believe that risks arising from our employee compensation policies and practices are not reasonably likely to have a material adverse effect on the Company.

Anti-Hedging Policy

Our anti-hedging policy is disclosed on our website under “Investors”, “Governance” and “Insider Trading Policy”. Our Insider Trading Policy on page 68 of this Proxy Statement makes it clear that Section 16 persons (the Company's executive officers, members of the Board, and stockholders who possess more than 10% of the Company's common stock) may not engage in short sales and “may not engage in transactions in publicly traded options on Company securities (such as puts, calls and other derivative securities) on an exchange or in any other organized market.” We also prohibit holding Company stock in a margin account or pledging Company securities as collateral for a loan. The information on our website is not part of this Proxy Statement and is not deemed to be incorporated by reference herein.

(1)Salary includes amounts deferred under the 401(k) and Executive Deferred Compensation Plans.

(2)In order to ensure leadership stability and retention among the NEOs during the Company’s CEO and strategic transition, retention awards were made to Mr. Kelley and Mr. O'Neill in 2017 that paid out in two installments in 2018 and 2019. In addition, Ms. Waterman and Mr. Craig received new hire cash payments upon commencing employment with the Company in 2021.

(3)The awards shown in this column include performance stock unit, restricted stock unit, and accelerated performance stock unit grants under the TreeHouse Foods, Inc. Equity and Incentive Plan in 2019 and performance stock unit and restricted stock unit grants in 2020 and 2021. The amounts listed above are based on the grant date fair market value of the awards computed in accordance with FASB ASC Topic 718. Due to the uncertainty in 2020 and 2021, we chose to not set a three year performance goal for our financial performance stock units, but rather will set annual goals for each of the three years in the performance cycle at the beginning of each year and a cumulative goal for the 2020 grant. In 2021 we introduced a new design with three one year measurement periods for our financial performance metrics and a three year measurement period for our new r-TSR performance metric.

Thomas E. O'Neill	188,139	95,390	95,366	381,457	760,352

Therefore, our performance stock unit awards earned based on the achievement of financial performance metrics, have a grant date fair value for financial accounting purposes for the portion of the award subject to the current year performance criteria only. The portion of the 2021 award based on the achievement of r-TSR has a grant date fair value for financial accounting purposes for the full portion of that award. The plan design change from 2020 to 2021 resulted in an increase in the grant date fair value due to the financial accounting requirements even though the target awards to the NEOs were unchanged. The performance stock units awarded in 2021 were 49,423 for Mr. Oakland, 8,201 for Mr. Kelley, 5,225 for Mr. Fleming and 7,089 for Mr. O'Neill. If maximum performance is achieved for the 2020 and 2021 performance stock units subject to 2021 performance criteria, the aggregate grant date fair value in the Stock Awards column is as detailed below.

	2020	188,139	376,278

(4)The amounts in this column reflect the earned awards under our Annual Incentive Plan (“AIP”). Because the Company did not meet certain performance targets, no payments were made under our AIP in 2021. For more information on the AIP, see “Our Performance-Based Compensation Structure – Annual Incentives”.

(5)None the NEOs have pension benefits or participate in the deferred compensation plan.

(6)The following table shows “All Other Compensation” amounts for 2021 for the NEOs. These include cash payments in lieu of perquisites, personal use of the Company’s corporate aircraft, life insurance premiums, matching contributions under the Company’s 401(k) plan, relocation, separation payments and consulting fees for former employees as detailed below:

(1)The amounts shown reflect the possible payout range under our 2021 Annual Incentive Plan (AIP), which are payable in cash. The AIP is the Company's annual bonus plan that is based on the Company’s achievement of financial performance and strategic objectives. For the actual amounts earned pursuant to the AIP for 2021, see the “Non-Equity Incentive Plan Compensation” column of the Summary Compensation Table. For a detailed discussion of the AIP, including targets and plan mechanics, see “Our Performance-Based Compensation Structure – Annual Incentives.” Payouts can range from 0% -200%. Awards under the AIP for NEOs are determined using their eligible earnings and individual incentive target percentages for the plan year.

(2)Consist of restricted stock units granted under the TreeHouse Foods, Inc. Equity and Incentive Plan that, except with regard to the December 29, 2021 RSUs, vest in three equal installments commencing on the first anniversary of the grant date, subject to the grantee’s continued employment with the Company from the grant date through each vesting date. Ms. Waterman's 7/30/2021 and Mr. Craig's 9/1/2021 awards represent sign-on equity grants. The December 29, 2021 RSUs will vest in three equal installments on each of the six, twelve and eighteen month anniversaries following the grant date. The value of the RSU award at vesting will depend on the closing price of the Company’s common stock on each vesting date. For more information regarding the RSU award, see “Our Performance-Based Compensation Structure – Long-Term Incentives – Restricted Stock Units.”

(3)Consist of performance stock units granted under the TreeHouse Foods, Inc. Equity and Incentive Plan. For a discussion of the awards, including targets and plan mechanics, see the Compensation Discussion and Analysis. Goals are set annually for the 2020-2022 and 2021-2023 performance awards. Therefore, our performance stock unit awards do not have a grant date fair value for financial accounting purposes except for that portion of the award subject to the current year performance criteria. The table reflects the portions of the 2020 and 2021 performance stock unit awards subject to 2021 performance criteria. The threshold assumes the minimum performance level necessary to generate an award.

2021 Non-Qualified Deferred Compensation

Our Deferred Compensation Plan allows certain employees, including the NEOs, to defer receipt of up to 100% of eligible salary and/or bonus payments on a tax deferred basis. Deferred amounts are credited with earnings or losses based on the rate or return of mutual funds selected by the participants in the Plan. We do not "match" amounts that are deferred by employees in the Deferred Compensation Plan.

Distributions are paid either upon termination of employment or at a specified date (at least 2 years after the original deferral) in the future, as elected by the employee. The employee may elect to receive payments in either a lump sum or a series of installments. The Deferred Compensation Plan is not funded by the Company, and participants have an unsecured contractual commitment from the Company to pay the amounts when due. When such payments are due to employees, the cash will be distributed from the Company's general assets.

None of our NEOs participated in the Deferred Compensation Plan in 2021.

Retirement Plans

None of the NEOs are eligible to participate in a defined benefit pension plan. The Company does offer a defined contribution 401(k) plan, which permits employee deferrals and provides for an employer matching contribution. All NEOs other than Ms. Waterman and Mr. Craig were participants in the 401(k) plan in 2021.

401(k) Plan

The TreeHouse Foods 401(k) Plan provides a dollar-for-dollar matching contribution each pay period on employee pre-tax and/or Roth after-tax contributions, up to the first 5% of eligible compensation. Employees are permitted to contribute up to 80% of eligible compensation on a pre-tax and/or Roth after-tax basis and up to 80%of eligible compensation as after-tax contributions, subject to IRS limits.

Potential Payments Upon Termination or Change in Control

Benefits upon termination are provided for in either an Executive’s individual employment agreement (Mr. Oakland) or the Executive Severance Plan (other NEOs). The rights upon termination of Executive’s employment depend upon the circumstance of the termination.

Executive Compensation

Termination Without Change in Control

Central to an understanding of the rights of each NEO under the agreements is an understanding of the definitions of “Cause” and “Good Reason” that are used in the employment agreements and the Severance Plan:

Cause: Under the individual employment agreements for Mr. Oakland, as well as under the Severance Plan, a termination for “Cause” may occur if the NEO has engaged in any of a list of specified activities, including refusing to perform duties consistent with the scope and nature of his position, committing an act materially detrimental to the financial condition and/or goodwill of us or our subsidiaries, commission of a felony or other actions specified in the definition.

•Payments: Under the individual employment agreements and the Severance Plan, an NEO is not eligible for any severance benefits in the event of a termination for Cause.

Good Reason: Under the terms of his employment agreement, Mr. Oakland may terminate his employment for “Good Reason” if there is an assignment of duties that is materially inconsistent with his position, a reduction in compensation, or certain other actions specified in the agreement. Under the terms of the Severance Plan (applies to all other NEOs), the participant is said to have Good Reason to terminate his employment and thereby gain access to the benefits described below if there is a reduction in compensation other than a reduction of no more than ten percent (10%) which applies to all Executive Officers of the Company, or a call for relocation. Following a Change in Control, Good Reason shall also include a material reduction in the Executive’s duties and responsibilities, or the assignment of duties and responsibilities that are materially inconsistent with the Executive’s duties.

Payments following an involuntary termination without Cause or a voluntary termination for Good Reason:

•Mr. Oakland: Two times base salary and target bonus plus continuation of certain health and welfare benefits for up to two years.

•Other NEOs as covered under the Executive Severance Plan: Base salary and target bonus plus continuation of certain health and welfare benefits for up to one year.

The employment agreements and Executive Severance Plan require, as a precondition to the receipt of these payments, that the NEOs sign a standard form of release in which the NEO waives all claims that the NEO might have against us and certain associated individuals and entities. The NEO’s employment agreements also include non-compete and non-solicit provisions that would apply for a period of one year following the NEO’s termination of employment, and confidentiality provisions that would apply for an unlimited period of time following the NEO’s termination of employment. The Executive Severance Plan includes non-solicit provisions.

Termination Following a Change in Control

Payments following a termination without Cause or resignation for Good Reason (as defined above) within a 24-month period immediately following a change-in-control of the Company:

•Mr. Oakland will receive three times the amount of base salary and target bonus plus continuation of certain health and welfare benefits for up to three years.

•Other NEOs as covered under the Executive Severance Plan: Two times base salary and target bonus plus the continuation of certain health and welfare benefits for two years.

The individual employment agreements and the Executive Severance Plan do not provide a “gross-up” payment from the Company to the extent covered individuals incur excise taxes under Section 4999 of the Code.

2022 Proxy Statement 63

Executive Compensation

Treatment of Equity Awards

The Company has issued equity awards to our NEOs that are subject to the terms and conditions of the Equity and Incentive Plan.

In the event of a voluntary or involuntary termination of the NEO without Cause, or resignation by the NEO for Good Reason, no unvested options shall become vested or exercisable, nor will unvested restricted stock or restricted stock units vest. For performance unit awards, the NEO shall receive accrued awards plus a pro rata portion of the award (based on the number of full calendar months served during the performance period divided by the length of the performance period) that would have accrued for the performance period in which the NEO was terminated without Cause by the Company.

In the event of a change in control, the Equity and Incentive Plan provides that each outstanding award may be assumed by the acquirer or replaced with an economically equivalent award. Any such assumed or replaced award will vest in full if a participant’s employment is terminated without Cause or due to Good Reason within the 24 months following the change in control. Performance conditions applicable to performance-based awards that are assumed or replaced will be deemed satisfied at the greater of target or actual performance through the date of the change in control, and such awards will be subject only to vesting based on the passage of time for the remainder of the original performance period. If the acquirer does not assume outstanding awards or replace outstanding awards with economically equivalent awards, such awards will be treated as follows: (i) unvested stock options will become fully vested; (ii) the restrictions on the restricted stock and restricted stock units will lapse, and (iii) performance units will be canceled in exchange for a payment equal to the value that would have been payable had each performance unit been deemed equal to 100% (or such greater or lesser percentage as determined by the Compensation Committee) of its initially established dollar value. The Compensation Committee may instead provide that outstanding awards that are not assumed or substituted with economically equivalent awards in connection with a change in control will be canceled in exchange for a cash payment.

In the event of death or disability, unvested options will become fully vested, and upon death, disability or retirement, a pro rata portion of the restricted stock and restricted stock units that would be eligible for lapse of restrictions on the next anniversary date of the grant will lapse. All unvested stock options, restricted stock and restricted stock unit awards will be forfeited for any other reason of termination. For the performance units, the NEO shall receive accrued awards plus a pro-rata portion of the award (based on number of full calendar months served during the performance period divided by the length of the performance period) that would have accrued for the performance period in which the NEO was terminated due to death, disability, or retirement.

64 2022 Proxy Statement

Executive Compensation

Treatment of Annual Incentives

In the event of a voluntary or involuntary termination of the NEO without Cause, or resignation by the NEO for Good Reason, no portion of the Annual Incentive Award will be received by the NEO.

In the event of death, disability, or retirement, the NEO will receive a pro-rata portion of the Annual Incentive Award (based on the number of days served during the performance period divided by the length of the performance period).

In the event of a change in control without termination, no portion of the Annual Incentive Award will be received by the NEO.

The following tables illustrate the payouts to each NEO under each of the various separation and change in control situations. The tables assume that the events took place on the last business day of the fiscal year ended December 31, 2021. Some of the NEOs may be subject to the "best net" provision in an Involuntary Termination without Cause or resignation for Good Reason following a Change in Control.

Executive Compensation

(1)Performance share units are represented based upon attainment of target performance.

(2)Mr. Kelley is retirement eligible under the Annual Incentive and Equity and Incentive Plans, and is therefore eligible to receive a pro-rated portion of the annual incentive, restricted stock units, and performance unit/cash awards.

CEO Pay Ratio

Our CEO pay ratio, calculated in accordance with the requirements set for in Item 402(u) of Regulation S-K, is 95:1.

•Mr. Oakland's total annual compensation was $5,969,207; and

•Our median employee was a full-time, hourly, United States based employee with total annual compensation of $62,770.

TreeHouse Foods is a global private-label food manufacturer with 10,056employees, excluding the CEO, as of October 1, 2021. Our median employee was identified using the Company's global full-time, part-time, temporary, and seasonal employees employed on that date. As part of our methodology, and as permitted under the pay ratio rule, we excluded all employees in Italy (90total employees excluded, which is less than 1% of our total workforce).

We then measured compensation for the period beginning January 1, 2021 and ending on December 31, 2021 for the remaining employees. Each employee's 2021 earnings (gross pay) was used as our consistently applied compensation measure to identify the median employee, and in doing so we annualized the compensation for our permanent full-time and part-time employees who were newly hired during 2021 and therefore not employed for the full measurement period.

After identifying the median employee, we calculated that employee's total annual compensation in the same manner as for the NEOs in the 2021 Summary Compensation Table ("SCT") and added the value of non-discriminatory benefits. The annual total compensation of our Chief Executive Officer and President, Mr. Oakland, is his total compensation from the SCT plus the value of non-discriminatory benefits.

Insider Trading Policy

An excerpt from the Company’s Insider Trading Policy regarding hedging of Company securities is set forth below:

Scope of Policy

Persons Covered. This Insider Trading Policy (this “Policy”) applies to all directors, officers, associates, employees, agents and consultants of the Company and any subsidiaries and affiliated companies. In this Policy, references to “you” include:

•your family members who reside with you;

•anyone else who lives in your household;

•any family members who do not live in your household but whose transactions in securities are directed by you or are subject to your influence or control (such as parents or children who consult with you before they trade in securities);

•any person to whom you have disclosed material, nonpublic information; and

•any person acting on your behalf or on behalf of any individual listed above.

You are responsible for making sure that the purchase or sale of any security covered by this Policy by any such person complies with this Policy.

Securities Covered. Although it is most likely that the "material, nonpublic information" you possess will relate to the common stock of the Company, the Company may from time to time issue other securities that are publicly traded and, therefore, subject to this Policy. In addition, this Policy applies to purchases and sales of the securities of other entities, including customers or suppliers of the Company and entities with which the Company may be negotiating major transactions (such as an acquisition, investment or sale of assets). Information that is not material to the Company may nevertheless be material to those entities.

Other Trading Restrictions

The Company considers it improper and inappropriate for you to engage in short-term or speculative transactions in Company securities or in other transactions in Company securities that may lead to inadvertent violations of the U.S. insider trading laws. Accordingly, your transactions in Company securities are subject to the following guidance.

Short Sales. You may not engage in short sales of Company securities (sales of securities that are not then owned), including a "sale against the box" (a sale with delayed delivery).

Publicly Traded Options. You may not engage in transactions in publicly traded options on Company securities (such as puts, calls and other derivative securities) on an exchange or in any other organized market.

Standing Orders. Standing orders should be used only for a very brief period of time. A standing order placed with a broker to sell or purchase stock at a specified price leaves you with no control over the timing of the transaction. A standing order transaction executed by the broker when you are aware of material, nonpublic information may result in unlawful insider trading even if the standing order was placed at a time when you did not possess material, nonpublic information.

Margin Accounts and Pledges. Securities held in a margin account or pledged as collateral for a loan may be sold by the broker if you fail to meet a margin call or by the lender in foreclosure if you default on the loan. You may not have control over these transactions as the securities may be sold at certain times without your consent. A margin or foreclosure sale that occurs when you are aware of material, nonpublic information may, under some circumstances, result in unlawful insider trading. Because of this danger, you may not hold Company stock in a margin account or pledging Company securities as collateral for a loan.

Compensation Committee Interlocks and Insider Participation

No member of the Compensation Committee was, during the year ended December 31, 2021, an officer, former officer or employee of the Company or any of its subsidiaries. No executive officer of the Company served as a member of (i) the compensation committee of another entity in which one of the executive officers of such entity served on the Company’s Compensation Committee, (ii) the board of directors of another entity in which one of the executive officers of such entity served on the Company’s Compensation Committee, or (iii) the compensation committee of another entity in which one of the executive officers of such entity served as a member of the Company’s Board, during the year ended December 31, 2021.

Proposal 3 -		Ratification of the Selection of Independent Registered Public Accounting Firm
Deloitte & Touche LLP audited our financial statements for fiscal year 2021 and has been selected by the Audit Committee of our Board to audit our financial statements for fiscal year 2022. A representative of Deloitte & Touche LLP will attend the Annual Meeting, where he or she will have the opportunity to make a statement, if he or she desires, and will be available to respond to appropriate stockholder questions. Stockholder ratification of the selection of Deloitte & Touche LLP is not required by our By-laws. However, our Board is submitting the selection of Deloitte & Touche LLP to you for ratification as a matter of good corporate practice. If our stockholders fail to ratify the selection, our Audit Committee will reconsider whether or not to retain Deloitte & Touche LLP. Even if the selection is ratified, the Audit Committee, in its discretion, may direct the appointment of a different independent registered public accounting firm if they determine such a change would be in the best interests of the Company and the Company’s stockholders. The affirmative vote of a majority of the votes cast is required to approve this Proposal 3. For information regarding audit and other fees billed by Deloitte & Touche LLP for services rendered in fiscal years 2020 and 2021, see “Fees Billed by Independent Registered Public Accounting Firm” on page 70 in this Proxy Statement.
	The Board and Audit Committee recommend that stockholders vote FOR the ratification of the selection of our independent registered public accounting firm for the fiscal year ending December 31, 2022.
Proxies solicited by the Board will be voted for the ratification of the selection of our independent registered public accounting firm unless stockholders specify a contrary vote.

Selection of Independent Registered Public Accounting Firm

The Audit Committee reviews and approves the scope and cost of all services, both audit and non-audit, provided by the firm selected to conduct the audit. The members of the Audit Committee and the Board believe that the continued retention of Deloitte & Touche LLP to serve as the Company’s independent registered public accounting firm is in the best interests of the Company and its stockholders. In reaching this conclusion, the Audit Committee considered Deloitte & Touche LLP’s integrity, controls and processes to ensure Deloitte & Touche LLP’s independence, objectivity, industry and company-specific experience, quality and effectiveness of personnel and communications, commitment to serving the Company, appropriateness of fees for audit and non-audit services, external data on audit quality and performance, including recent Public Company Accounting Oversight Board ("PCAOB") reports on Deloitte & Touche LLP and tenure as the Company’s auditors, including the benefits of having a long-tenured auditor.

Audit Matters

Report of the Audit Committee

The Audit Committee is currently composed of five independent directors, Messrs. Hunter, Buchanan, Tuchman, Tyler, and Ms. Rahman, and operates pursuant to a written charter. The Company’s management is responsible for its internal accounting controls and the financial reporting process. The Audit Committee is responsible for overseeing and monitoring the integrity of the Company’s financial statements, accounting and financial reporting processes, systems of internal control over financial reporting, compliance with legal and regulatory financial accounting requirements, audits of the Company’s financial statements, and review of the performance of the Audit Committee. The Audit Committee also regularly receives and reviews reports from the third party whistleblower hotline provider.

The Company’s independent registered public accounting firm, Deloitte & Touche LLP, is responsible for performing an independent audit of the Company’s consolidated financial statements and internal controls over financial reporting in accordance with the standards of the Public Company Accounting Oversight Board (“PCAOB”) and to issue reports thereon. The Audit Committee’s responsibilities are to monitor and oversee the audit process, and to appoint, compensate and evaluate the performance of the independent registered public accounting firm.

In discharging its oversight responsibility as to the audit process, the Audit Committee obtained from the independent registered public accounting firm a formal written statement describing all relationships between the independent registered public accounting firm and the Company that might bear on the independent registered public accounting firm’s independence consistent with applicable requirements of the PCAOB and discussed with Deloitte & Touche LLP any relationships that may impact its objectivity and independence, and the Audit Committee satisfied itself as to Deloitte & Touche LLP’s independence. The Audit Committee has reviewed and discussed the audited financial statements for the year ended December 31, 2021 with management. The Audit Committee also discussed with management and Deloitte & Touche LLP the quality and adequacy of the Company’s internal controls and the internal audit department’s organization, responsibilities, budget and staffing. The Audit Committee reviewed both with Deloitte & Touche LLP and the internal auditors their audit plans, audit scope, and identification of audit risks.

The Audit Committee discussed and reviewed with Deloitte & Touche LLP all matters required by the applicable requirements of the PCAOB and the SEC, and, with and without management present, discussed and reviewed the results of Deloitte & Touche LLP’s audit of the financial statements. The Audit Committee also discussed the results of the internal audit examinations.

Based on the Audit Committee’s aforementioned discussions with management and Deloitte & Touche LLP and the Audit Committee’s review of the representations of management and the report of the independent registered public accounting firm, the Audit Committee recommended to the Board that the audited consolidated financial statements be included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021, for filing with the SEC.

In order to assure that the provision of audit and non-audit services provided by Deloitte & Touche LLP, our independent registered public accounting firm, does not impair its independence, the Audit Committee is required to pre-approve all audit services to be provided to the Company by Deloitte & Touche LLP, and all other services, including review, attestation and non-audit services, other than de minimis services that satisfy the requirements of the New York Stock Exchange and the Exchange Act, pertaining to de minimis exceptions.

This report is respectfully submitted by the
Audit Committee of the Board.

2022 Proxy Statement 73

Stock Ownership

Delinquent Section 16(a) Reports

Section 16(a) of the Exchange Act requires the Company’s officers and directors and persons who own more than 10% of a registered class of the Company’s equity securities (collectively, the “Reporting Persons”) to file reports of ownership and changes in ownership with the SEC. Based on the Company’s review of these reports filed electronically with the SEC and written representations received from Reporting Persons, we believe that all of our directors and officers complied with the reporting requirements of Section 16(a) of the Exchange Act during 2021, except with respect to one Form 4 for Mr. Sean Lewis (one reporting transaction), due to an unanticipated delay in obtaining the reporting person's EDGAR filing codes.

74 2022 Proxy Statement

Summary of the Annual Meeting

We are furnishing this Proxy Statement in connection with the solicitation of proxies by the Board for use in voting at the Annual Meeting. Due to the continuing public health impact of the novel coronavirus (COVID-19) pandemic, and to support the health and well-being of our stockholders, employees, directors, and communities, the Annual Meeting will be held in a virtual-only format. The Annual Meeting will take place on Thursday, May 26, 2022, at 9:00 a.m. Central Daylight Time, via a live webcast accessible at https://viewproxy.com/treehousefoods/2022/VM, for the purpose of considering and acting upon the matters specified in this Proxy Statement and the accompanying notice of annual meeting of stockholders. While there will be no physical location for in-person attendance at the Annual Meeting, we designed the format of this year’s virtual Annual Meeting to provide our stockholders of record and beneficial owners of shares who pre-register for and attend the Annual Meeting online through the live webcast with rights and opportunities to participate similar to those they would have at an in-person meeting. This Proxy Statement is being sent to stockholders on or about April 27, 2022.

Who May Vote

If you are a stockholder of record on April 19, 2022, you are entitled to vote at the Annual Meeting. You are entitled to one vote for each share of Common Stock you own, without cumulation, on each matter to be voted upon at the Annual Meeting. If you are the beneficial owner of shares held in “street name” on April 19, 2022 through a bank, broker or other nominee that is the record holder of those shares, and you wish to vote your shares at the Annual Meeting, you will need to contact your bank, broker or other nominee to obtain a legal proxy.

How To Vote

Shares of Common Stock that are entitled to be voted at the Annual Meeting and are represented by properly executed proxies will be voted in accordance with the instructions on those proxies. You may vote by proxy or, at the virtual Annual Meeting, by electronic ballot. Whether or not you plan to attend the Annual Meeting through the live webcast, you are encouraged to read the Proxy Statement and vote your shares as soon as possible to ensure that your shares are represented and voted at the Annual Meeting.

If you hold your shares as a stockholder of record:

•Voting Before the Meeting: You may vote your shares by proxy by following the instructions provided on the enclosed proxy card for voting over the phone or via the Internet or by completing, signing, dating and returning your proxy card in the postage-paid envelope provided.

•Voting at the Meeting: Alternatively, you may vote your shares by electronic ballot at the Annual Meeting if you attend the virtual Annual Meeting through the live webcast by following the instructions set forth below under “How to Attend the Annual Meeting—Stockholders of Record” and “How to Attend the Annual Meeting—How to Access the Annual Meeting.”

If you are the beneficial owner of shares held in “street name” through a bank, broker or other nominee that is the record holder of those shares:

•Voting Before the Meeting: Please follow the instructions you received from the holder of record to vote those shares by proxy.

•Voting at the Meeting: Alternatively, you may vote those shares by electronic ballot at the Annual Meeting if (i) you attend the virtual Annual Meeting by following the instructions set forth below under “How to Attend the Annual Meeting—Beneficial Owners” and “How to Attend the Annual Meeting—How to Access the Annual Meeting” and (ii) you obtain a legal proxy from the record holder of those shares and submit that legal proxy when voting online during the Annual Meeting.

You are encouraged to vote by proxy in advance of the Annual Meeting and return your proxies by Internet or by telephone, given the circumstances relating to COVID-19, and we encourage you to vote as early as possible to avoid any processing delays. If you have already voted by proxy, you do not need to vote by electronic ballot at the Annual Meeting, unless you intend to change your vote.

2022 Proxy Statement 75

Summary of the Annual Meeting

Many of our stockholders hold their shares in more than one account and may receive separate proxy cards or voting instructions forms for each of those accounts. If you receive more than one proxy card, your shares are registered in more than one name or are registered in different accounts. Please sign, date and return or otherwise submit your proxy with respect to each proxy card to ensure that all of your shares are voted.

Giving Specific Voting Instructions

Stockholders of Record

If your proxy card is properly returned as directed on the proxy card, the shares it represents will be voted at the Annual Meeting in accordance with your instructions.If you execute and return your proxy card but do not give specific instructions, your shares will be voted as follows:

•FOR the election of each of the three nominees for director set forth herein;

•FOR the advisory approval of the compensation of the Company’s named executive officers as described in this Proxy Statement under “Executive Compensation”;

•FOR the ratification of the selection of Deloitte & Touche LLP as our independent registered public accounting firm for fiscal year 2022; and

•with respect to any other matter that may properly come before the Annual Meeting or any adjournment or postponement thereof, in the discretion of the persons voting the respective proxies.

The Board does not intend to bring any matters before the Annual Meeting except those indicated in this Proxy Statement and the Notice of Annual Meeting of Stockholders. If any other matters properly come before the Annual Meeting, however, the persons named in the enclosed proxy card, or their duly constituted substitutes acting at the Annual Meeting, will be authorized to vote or otherwise act thereon in their discretion on such matters.

Beneficial Owners

If you are the beneficial owner of shares held in “street name” through a bank, broker, or other nominee, such bank, broker, or nominee, as the record holder of the shares, must vote those shares in accordance with your instructions. If you do not give instructions to your broker, your broker can vote your shares with respect to “discretionary” items but not with respect to “non-discretionary” items. On non-discretionary items for which you do not give instructions, the shares will be treated as “broker non-votes.” A discretionary item is a proposal that is considered routine under the rules of the New York Stock Exchange (the “NYSE”).

Shares held in street name may be voted by your broker on discretionary items in the absence of voting instructions given by you. The proposal concerning the ratification of the independent registered public accounting firm (Proposal 3) is discretionary. All other proposals to be voted on at the Annual Meeting are non-discretionary and, accordingly, cannot be voted upon without your instruction.

How to Attend the Annual Meeting

The Annual Meeting will be held in a virtual-only format through a live webcast at https://viewproxy.com/treehousefoods/2022/VM.

Stockholders of TreeHouse as of the close of business on April 19, 2022, the record date, or those that hold a valid legal proxy for the meeting, are entitled to participate in and ask questions at the Annual Meeting.

2022 Proxy Statement 77

Summary of the Annual Meeting

Revoking a Proxy

Submitting your proxy now will not prevent you from voting your shares at the Annual Meeting if you desire to do so, as your proxy is revocable at your option.

If you are a stockholder of record, you may revoke your proxy at any time before it is voted at the Annual Meeting by:

•delivering to Kristy N. Waterman, our Executive Vice President, Chief Human Resources Officer, General Counsel, and Corporate Secretary, a signed written revocation letter dated later than the date of your proxy;

•submitting a proxy to the Company with a later date by mail, via the Internet or by telephone; or

•attending the Annual Meeting virtually and voting by electronic ballot (your virtual attendance at the Annual Meeting will not, by itself, revoke your proxy; you must also vote online during the Annual Meeting).

If you are the beneficial owner of shares held in “street name” through a bank, broker or other nominee that is the record holder of those shares, you must contact the appropriate bank, broker or nominee that is the record holder in order to revoke a proxy executed with respect to those shares.

Required Vote

The election of the nominees for director (Proposal 1) in an uncontested election will become effective, in the case of each nominee, only upon the affirmative vote of shares of Common Stock representing a majority of the votes cast “for” or “against” such nominee. The advisory approval of the compensation of the Company’s named executive officers as described in this Proxy Statement under “Executive Compensation” (Proposal 2), the ratification of the selection of our independent registered public accounting firm (Proposal 3), and the approval of any other matter that may properly come before the Annual Meeting will become effective only upon the affirmative vote of shares of Common Stock representing a majority of the votes cast “for” or “against” such proposal. Votes cast as “for” or “against” are counted as a vote, while votes cast as abstentions will not be counted as a vote but will be counted for purposes of determining a quorum. Abstentions will have no effect on Proposals 1, 2, and 3.

So-called “broker non-votes” (brokers failing to vote by proxy shares of the Common Stock held in nominee name for customers on any non-discretionary matters) will be counted in determining the quorum, but will not be counted as votes at the Annual Meeting and will not have a direct impact on any non-discretionary proposal (i.e., Proposal 1 and Proposal 2). Brokerage firms may vote un-instructed shares for or against Proposal 3.

Resignation Policy

Our Corporate Governance Guidelines utilize a resignation policy in connection with an uncontested election of directors. Accordingly, if, in an uncontested election, an incumbent director nominee receives a greater number of votes marked “against” his or her election than votes marked “for” his or her election, that nominee is required to tender his or her resignation following certification of the stockholder vote. The Nominating and Corporate Governance Committee is required to make recommendations to the Board with respect to any such resignation.

Method and Cost of Soliciting and Tabulating Votes

The solicitation of proxies from our stockholders is being made by the Board and management of the Company. TreeHouse will bear the costs of soliciting and tabulating your votes, including the cost of preparing and mailing the Proxy Statement, the proxy card, and our 2021 Annual Report. Alliance Advisors will act as our proxy solicitor in soliciting votes for a fee of approximately $25,000 plus the reimbursement of reasonable out of pocket expenses. Solicitation will be primarily through the use of the U.S. Postal Service and the Internet and by telephone. Our officers, directors, and regular employees may solicit proxies personally or by telephone or through the use of the Internet without additional remuneration for such activity.

TreeHouse will reimburse banks, brokers and other holders of record for reasonable, out-of-pocket expenses for forwarding these proxy materials to you, and obtaining proxies from you, according to certain regulatory fee schedules. The actual amount will depend on variables such as the number of packages mailed, the number of stockholders receiving electronic delivery, and postage costs.

Alliance Advisors will act as the proxy tabulator and inspector of elections at the Annual Meeting.

78 2022 Proxy Statement

Summary of the Annual Meeting

Householding

The SEC has adopted rules that permit companies and intermediaries (e.g., brokers) to satisfy the delivery requirements for proxy materials with respect to two or more stockholders sharing the same address by delivering a single Proxy Statement and Annual Report addressed to those stockholders. This process, which is commonly referred to as “householding”, potentially means extra convenience for stockholders and cost savings for companies. We have not implemented householding rules with respect to our record holders. However, a number of brokers with account holders who are stockholders may be “householding” our proxy materials. If a stockholder receives a householding notification from his, her, or its broker, a single Proxy Statement and Annual Report will be delivered to multiple stockholders sharing an address unless contrary instructions have been received from an affected stockholder. Once you have received notice from your broker that they will be “householding” communications to your address, “householding” will continue until you are notified otherwise.

Stockholders who currently receive multiple copies of the proxy materials at their address and would like to request “householding” of their communications should contact their broker. In addition, if any stockholder that receives a “householding” notification wishes to receive a separate Annual Report and Proxy Statement at his, her or its address, such stockholder should also contact his, her or its broker directly. Stockholders who in the future wish to receive multiple copies may also contact the Company at: 2021 Spring Road, Suite 600, Oak Brook, IL, 60523, Attention: Investor Relations or by phone at (708) 483-1331.

Stockholder Proposals for 2023 Annual Meeting of Stockholders

Any stockholder who intends to present proposals at the Annual Meeting of Stockholders in 2023 pursuant to Rule 14a-8 under the Exchange Act must send notice of such proposal to us so that we receive it no later than December 28, 2022. Any stockholder who intends to present proposals at the Annual Meeting of Stockholders in 2023 other than pursuant to Rule 14a-8 must comply with the notice provisions in our By-laws. The notice provisions in our By-laws require that, for a proposal to be properly brought before the Annual Meeting of Stockholders in 2023, proper notice of the proposal must be received by us not less than 90 days or more than 120 days prior to the first anniversary of this year’s meeting, or no earlier than January 26, 2023, and no later than February 24, 2023. Stockholder proposals should be addressed to TreeHouse Foods, Inc., 2021 Spring Road, Suite 600, Oak Brook, IL 60523, Attention: Corporate Secretary.
