LETTER FROM OUR

March 22, 2023

Dear Fellow Eastman Stockholders:

Thank you for your continued investment in Eastman. I, and the rest of the Board of Directors, invite you to attend the 2023 Annual Meeting of Stockholders. Our meeting, once again, will be held virtually on May 4, 2023, at 11:30 a.m. (EDT) via live webcast, though stockholders may log-in beginning at 11:15 a.m. (EDT). We encourage you to access the Annual Meeting prior to the start time. The business to be considered and voted upon at the meeting is explained in this proxy statement. A copy of Eastman’s 2022 Annual Report to Stockholders is also included with these materials.

As I reflect on 2022, first and foremost I want to thank the global Eastman team. Demonstrating agility, resilience, and determination, the team progressed our long-term strategy of growth through innovative, sustainable materials while navigating a dynamic macroenvironment. I am tremendously proud of how the team worked to deliver for our customers and drive value for our stockholders.

Against a challenging economic backdrop, we advanced our innovation programs and transformational initiatives and made progress on our ambitious environmental, social and corporate governance (ESG) goals and safety performance. We achieved a number of milestones in our circular platform, further establishing ourselves as a leader in building a circular economy. Our work in this area is just beginning as we aim to help solve the world’s biggest problems while creating a new vector of attractive growth for Eastman.

2022 in Review

Last year started with strong demand driven by a growing economy. Through the first half of the year, we delivered strong financial performance, including our best second-quarter results in Eastman’s history. Beginning in the back half of the year, and particularly in the fourth quarter, global dynamics in the macroenvironment began to quickly shift, resulting in economic uncertainty and broad demand challenges that were widespread across key end markets and geographies. The conditions escalated in the fourth quarter due to exceptional challenges in demand, aggressive inventory destocking, and the impact of Winter Storm Elliott. In addition, our growth in the first three quarters of 2022 was limited by operational and supply chain disruptions.

In these challenging circumstances, the Eastman team achieved numerous accomplishments worth highlighting:

| • |  | Returned cash to stockholders – Eastman returned approximately $1.4 billion to stockholders through share repurchases and dividends. We have raised our dividend for 13 consecutive years, a tangible reflection of our strong financial position and our commitment to returning cash to our stockholders.

| • |  | Generated strong operating cash flow – We generated approximately $1 billion in operating cash flow, demonstrating resilience in a challenging environment and delivering above prior-year levels in the fourth quarter.

| • |  | Demonstrated commercial excellence – In a year where our raw material, energy, and distribution costs increased by approximately $1.3 billion, our business teams demonstrated commercial excellence by raising our selling prices to keep pace with extraordinary inflation.

2023 Proxy Statement

| • |  | Leveraged our innovation-driven growth model to generate growth – Our commercial teams did an outstanding job of driving new business wins across our portfolio of specialty products. In 2022, we closed more than $550 million of new business revenue from market development and innovation.

| • |  | Achieved milestones on circular platform, Eastman’s new vector of growth – We celebrated a number of achievements on each of our planned methanolysis projects, going from one facility under construction to all three projects fully in development.

| • |  | Strengthened portfolio – We completed the divestiture of the adhesives resins product lines in second quarter 2022 for a total purchase price of $1 billion, giving us the opportunity to drive results in a more stable, focused Additives & Functional Products segment.

| • |  | Further integrated sustainability and ESG into how we win – We further increased transparency and accountability in how we drive ESG throughout our organization. We published our 2022 Sustainability Report, “A Better Circle,” reporting our progress toward our 2030/2050 sustainability commitments. We also launched our second Inclusion and Diversity (I&D) Annual Report, “Globally United,” in which we reported progress on our I&D strategy of shaping a more diverse culture.

Sincerely,

MARK J. COSTA

CEO and Board Chair

A Leader in the Circular Economy

As we look ahead, we are unwavering in our commitment to creating A Better Circle. I am proud of the work that we have done to institute meaningful and measurable goals that ensure progress toward the ESG expectations of our stakeholders–designing sustainable solutions and scaling positive societal impact while also delivering financial value to our stockholders. Our goals and objectives are structured across the three pillars of mitigating climate change, mainstreaming circularity, and caring for society, which is what we call “the triple challenge.”

Your Vote is Important for this Year’s Annual Meeting

We encourage you to vote your shares for this year’s Annual Meeting regardless of the number of shares you own. Signing and returning a proxy card or submitting your proxy by Internet or telephone in advance of the meeting will not prevent you from voting electronically during the meeting if you attend virtually, but will assure that your vote is counted if you are unable to attend the meeting online. Whether you choose to vote by proxy card, Internet or telephone, I urge you to vote as soon as possible.

Thank you for your support of our Company. We look forward to welcoming you to our Annual Meeting.

2023 Proxy Statement

LETTER FROM OUR LEAD DIRECTOR

March 22, 2023

|  | Dear Fellow Eastman Stockholders: Since May 2020, I have been fortunate to serve as Lead Director of the Eastman Board of Directors. In that role, I am responsible for providing independent leadership to the Board of Directors. In this year’s letter to stockholders, I wanted to provide a snapshot of not only my role as Lead Director, but also the role and responsibilities of the independent directors. Since the Company implemented the Lead Director role in 2011, the average tenure in the role has been three to four years. A summary of the key responsibilities of the Lead Director is included below. A more complete description is available in the Company’s Corporate Governance Guidelines, which are available in the Investors section on www.eastman.com.

As Lead Director, my key responsibilities include the following:

| • |  | calling, setting agendas for, and presiding over executive sessions of the non-employee, independent directors at each regularly scheduled meeting of the Board, or at such other times as the non-employee, independent directors may determine;

| • |  | calling special meetings of the full Board or the non-employee, independent directors;

| • |  | presiding over Board meetings in the absence of the Board Chair;

| • |  | collaborating and consulting with the chairs of the Board committees concerning, among other things, schedules, agendas, and written materials for the meetings;

| • |  | acting as a liaison between the independent directors and the Board Chair;

| • |  | receiving and evaluating substantive direct communications from interested parties to non-employee, independent directors; and

| • |  | being available with the Chair for consultation and direct communication with stockholders.

As a Board, it is critical that we represent a diverse group of cultures, backgrounds and experiences that enable us to develop and oversee the implementation of a long-term strategy for Eastman to create value for stockholders, build a world-class culture and deliver sustainable solutions. Our Board is committed to ensuring that it is well-equipped to oversee the Company’s business and effectively represent the interests of stockholders. Our Board regularly reviews its composition to ensure it includes directors with the experience, skills, and diversity necessary for effective, independent Board oversight. Since 2020, we have added four new directors to the Board, and we are committed to appropriately refreshing the Board focusing on critical skills, experience, leadership and diversity.

Importantly, the Board’s primary responsibility is to serve the Company’s and its stockholders’ best interests and create value. In addition, key responsibilities of the Board include, among others: (i) strategic planning, (ii) hiring, monitoring and evaluating the Chief Executive Officer, (iii) management oversight and succession planning, (iv) risk management, and (v) governance and compliance. At each Board meeting, I lead a discussion with the non-employee, independent directors (all directors other than the CEO) to ensure that we, as a Board, are fulfilling our responsibilities.

Integrating ESG into Our Strategy

The Board oversees the strategic and operational direction of the Company, as well as risks associated with our strategy. Integrated into Eastman’s strategy are our ESG and sustainability initiatives. Over the past year, Eastman has taken significant steps to more clearly define these initiatives and how they link to the Company’s growth strategy. The Company made great progress on these initiatives in 2022.

During 2022, the Company made significant progress on its sustainability goals including the advancement on its three material-to-material molecular recycling facilities. Using technology with a lower carbon footprint, these facilities will enable the Company to recycle hard-to-recycle plastic waste that is currently being incinerated or sent to landfills. The Board believes these bold and ambitious projects position Eastman as a leader in the circular economy that will create a new vector of growth for the Company. Additional detail around these and other ESG initiatives can be found within the pages of this proxy statement. I encourage you to also review Eastman’s sustainability report, A Better Circle, which you can find on www.eastman.com.

Our Culture of Inclusivity and Diversity

I would also like to highlight the Company’s efforts to grow and strengthen its culture of inclusivity and diversity. The Company has accelerated its efforts to create an environment that fosters a sense of belonging, acceptance, and safety. This is an area of great interest to the Board, with members engaging through regular progress updates, as well as engaging with employees. To increase transparency and accountability in this area, Eastman published its second Inclusion and Diversity Annual Report in 2022, which details the Company’s

strategy and progress against the Company’s goals. As another measure of accountability, the Board has taken steps to provide greater alignment between the outcomes of the Company’s I&D and ESG efforts and executive compensation by including related performance goals in the Company’s long-term incentive compensation program.

Our Commitment to Creating Long-Term Value

While 2022 presented challenges with respect to supply chain disruptions, significant inflation and a weakening global economy, the Board and management are focused on mitigating the impacts of these challenges and positioning Eastman for strong growth. As Lead Director, I can assure you the Board is excited by the progress the Company continues to make on its innovation-driven growth strategy. Your Board is highly engaged on the Company’s approach to creating long-term value for stockholders. We take our responsibilities seriously and understand the trust you place in us to act in your best interests. As Company stewards, we are focused on supporting the strategies and approaches that will deliver strong financial performance and long-term sustainable growth.

On behalf of the Board of Directors, I thank you for the trust that you have placed in us. We look forward to serving your interests throughout the upcoming year.

Sincerely,

DAVID W. RAISBECK

Lead Director

ABOUT THE COMPANY

Eastman Overview

Eastman Chemical Company (“Eastman” or the “Company”) is a global specialty materials company that produces a broad range of products found in items people use every day. Eastman began business in 1920 for the purpose of producing chemicals for Eastman Kodak Company’s photographic business and became a public company, incorporated in Delaware, on December 31, 1993. As a globally inclusive and diverse company, Eastman employs approximately 14,500 people around the world and serves customers in more than 100 countries.

Driven by more than 100 years of continuous innovation, Eastman is bringing sustainable materials to market and delivering financial value to our stockholders while scaling positive societal impact for our stakeholders.

At Eastman, we believe there are always solutions to the challenges the world faces. In fact, our innovations are driven with a specific goal in mind: to help solve the world’s greatest challenges by creating the most sustainable materials. Our strategy for that is founded in our commitment to the principles of the United Nations Global Compact, where our purpose, leadership and actions continue to guide us toward carbon neutrality, circularity and caring for society. This is what we call “the triple challenge,” and our expertise in material science provides the world’s largest industries — like packaging, automotive and architecture — with high-quality sustainable solutions that address those complex global issues we collectively face. We will continue partnering up and down our value chains to advance sustainable solutions to address the world’s big challenges.

With the purpose of enhancing the quality of life in a material way, Eastman works with customers to deliver innovative products and solutions while maintaining a commitment to safety and sustainability. The Company’s innovation-driven growth model takes advantage of world-class technology platforms, deep customer engagement, and differentiated application development to grow its leading positions in attractive end markets such as transportation, building and construction, and consumables.

Integrating Sustainability and ESG into Eastman’s Growth Strategy

Eastman continues to fully integrate sustainability and ESG into the Company’s market-differentiated growth strategy. Our strategy is to transform tomorrow by revolutionizing the materials that shape it today — innovating sustainable solutions to enhance the quality of life in a material way. We have a compelling and ambitious strategy to leverage our innovation-driven growth model to develop sustainable innovations that address the challenges of climate change, plastic waste, and a growing population. We have made bold commitments to mitigate climate change (including committing to be carbon neutral by 2050), and our technology platforms and several of our key product lines are linked to sustainable macro trends enabling market-driven solutions. Our corporate strategy is designed to drive organic growth while also driving our positive impact on society.

2023 Proxy Statement 1

About the Company

Enabling a Circular Economy — Creating a New Vector of Growth for Eastman

The global waste plastic crisis and climate change are two of the greatest challenges of our time, and the world desperately needs a materials revolution that will help address both. Brands are facing growing climate and environmental scrutiny from consumers, end users, non-governmental organizations, investors, and other stakeholders, resulting in companies setting aggressive goals to include recycled content in products. Each year, more than 300 million tons of plastic are produced globally and only about 15% are recycled today. Estimates are that roughly 25% is incinerated, about 40% is landfilled, and about 20% leaks into the environment — including our oceans.

Eastman seeks to be a leader in shifting from a linear economy (take, make, consume, waste) to a circular economy (make, use, reuse, remake, recycle). We’re committed to revolutionizing our materials to give them a longer life and richer purpose using our two advanced circular recycling technologies — carbon renewal and polyester renewal. A circular economy focuses on making the most of the world’s resources — minimizing waste and maximizing value by providing end-of-life solutions to reduce, reuse, and recycle products and materials that typically end up in landfills and our waterways.

Polyester renewal technology (PRT). Using PRT, we produce new polymers that serve a diverse set of end-markets, including medical devices, hydration, electronics, and cosmetic packaging. PRT takes polyester plastic wastes, like colored soft drink bottles, carpet fibers, or polyester-based clothing, and unzips the polymer chain back to its basic monomers to create new high-quality materials. The molecules produced are indistinguishable from materials made with virgin or nonrecycled content. The process allows us to recycle polyester waste over and over again without degradation of quality that often occurs with mechanical recycling. Based upon a third-party life cycle analysis, this process is expected to reduce greenhouse gas emissions by 20%-30% at the intermediate level when compared to processes using fossil feedstocks.

Carbon renewal technology (CRT). Using CRT, we produce biodegradable, cellulosic polymers that serve a variety of end-markets, including textiles, cosmetics and food service applications. While PRT only processes the polyester family of plastics, CRT can use a broad mixture of plastic waste, like complex mixed plastics, textiles, films, and carpet as feedstocks. CRT takes a wide array of mixed plastic waste and breaks it back down into its molecular building blocks, allowing the molecules to be reassembled to build new products. This allows materials to be recycled over-and-over — unlike mechanical recycling — with no compromise or loss of quality. This technology provides a circular solution for materials that currently cannot be recycled today, keeping them in use and out of landfills and incinerators. Better yet, the end products are identical to those produced with virgin content. Based upon a third-party life cycle analysis, the process reduces greenhouse gas emissions by 20%-50% at the intermediate level when compared to processes using fossil feedstocks.

Making the Future of Recycling a Reality Today

Construction is Near Completion on a Molecular Plastics Recycling Facility in Kingsport, Tennessee

Eastman announced a significant capital investment for a new methanolysis facility located at our largest manufacturing site located in Kingsport, Tennessee. This facility is expected to provide a unique, sustainable growth opportunity for Eastman given the demand for recycled material, the flexibility of our technology to use a variety of polyester waste plastic as a feedstock, the attractive GHG footprint relative to deriving the monomers from fossil feedstocks, and importantly, the expected price premium that consumers are willing to pay. The feedstock for this facility will be hard-to-recycle polyester waste plastic. We expect to begin commissioning and start-up activities for this facility by summer 2023.

Announcement of Plans to Build the World’s Largest Molecular Plastics Recycling Facility in France

On January 17, 2022, French President Emmanuel Macron and Eastman CEO Mark Costa jointly announced Eastman’s plan to invest up to $1 billion in a material-to-material molecular recycling facility in France that would use Eastman’s PRT to recycle up to 110,000 metric tons annually of hard-to-recycle waste plastic that is currently being incinerated. The site will be designed so that in a second phase, the amount of waste plastic used as a feedstock can be doubled in size to approximately 200,000 metric tons in a capital-efficient manner. Many global brands are leading the way by signing letters of intent for multi-year supply agreements from this facility. The plant and a recycling innovation center are expected to be operational by 2026.

Announcement of a Third Molecular Recycling Facility

In 2022, we entered into a definitive agreement with PepsiCo, which will be a baseload customer for a planned third molecular recycling facility that will be located in the United States. The first phase of this project will use approximately 110,000 metric tons annually of polyester waste plastic as feedstock and is expected to start operations in 2026. This site also will be designed so that in a second phase, the amount of waste plastic used as a feedstock can be doubled in size to approximately 200,000 metric tons in a capital-efficient manner. The polymers will be used by PepsiCo and other customers for packaging and textiles applications.

How we Innovate

Beyond these innovative recycling technologies, Eastman is pursuing specific opportunities to leverage our innovation-driven growth model for continued greater than end-market growth by both sustaining the Company’s leadership in existing markets and expanding into new markets.

Eastman uses an innovation-driven growth model which consists of leveraging world-class, scalable technology platforms, delivering differentiated application development capabilities, and relentlessly engaging the market.

About the Company

We are also changing our business and operations to improve our cost structure, increase investment in growth, and strengthen execution capabilities, including specific initiatives to transform operations, work processes and systems, and business structure alignment, scale, and integration.

Empowering our Employees to Build a World-Class Innovative Culture

In addition, our commitments to I&D extend to the highest levels of our Company. In 2022, we published our second I&D Report, which is available on our website (www.eastman.com), to provide greater transparency in this important area. We believe that to meet today’s most pressing needs, we must inspire innovative ideas by making every team member feel valued and empowered to do their best work.

| 1. | Mitigate unconscious bias

We strive to build inclusive leadership behaviors at all levels, so every team member can bring their full, authentic self to work and contribute fully. To do so, we use experiential workshops, educational resources and scorecards that equip leaders and their teams to recognize and mitigate the impact of unconscious biases. These initiatives provide a strong foundation for increasing engagement, driving results and promoting innovation.

| 2. | Foster an inclusive culture

True inclusion requires intentional actions that enable every team member to operate authentically at their best. To create an inclusive environment, we invest in Eastman Resource Groups (ERGs), learning opportunities, and systems and processes that promote allyship and encourage full engagement. Our goal is to ensure everyone who works at Eastman feels valued for what they bring to the business and fully accepted for who they are.

| 3. | Build inclusive teams

Innovative recruiting and hiring practices help us source and attract a broader pool of talent, opening pathways for the people we need. To that end, we have strengthened our sourcing strategies, selection processes and benefit programs to attract diverse talent, bring underrepresented groups to above industry levels, and meet the needs of a diverse world. These efforts include expanding our work with external partners, educating hiring managers on unintended barriers, and inviting candidates before they join the Company to build relationships with members of ERGs.

| 4. | Accelerate diversity in leadership

Eastman offers a range of personal and professional development opportunities to support the career aspirations of all team members. To address gaps in leadership representation, we prepare underrepresented colleagues for leadership roles through targeted development programs and inclusive talent review processes. We also provide tools and resources to boost leaders’ personal inclusiveness and the inclusivity of their teams.

2023 Proxy Statement 9

ITEM 1 — Election of Directors

Stockholders are being asked to vote on the election of twelve directors to serve until the 2024 Annual Meeting of Stockholders and their successors are duly elected and qualified. The terms of office of all twelve current directors will expire at the 2023 Annual Meeting of Stockholders (the “Annual Meeting”), and each of those directors has been nominated for re-election for a one-year term. If any nominee is unable or unwilling to serve (which we do not anticipate), the persons designated as proxies will vote your shares for the remaining nominees and for another nominee proposed by the Board of Directors (the “Board”) or, as an alternative, the Board could reduce the number of directors to be elected at the Annual Meeting.

Majority Vote Standard for Election of Directors. The Company’s Bylaws provide that directors are elected by a majority of votes cast by stockholders. If a nominee who is serving as a director is not re-elected by a majority of votes cast at a meeting, under Delaware law the director would continue to serve on the Board as a “holdover director.” However, under the director election provision of our Bylaws, any incumbent director who is a holdover director whose successor has not been elected by stockholders would be required to offer to resign from the Board. The Nominating and Corporate Governance Committee would then make a recommendation to the Board whether to accept or reject the resignation, or whether other action should be taken. The Board would act on the recommendation and publicly disclose its decision and rationale within 90 days from the date the election results are certified. The director who tenders his or her resignation would not participate in the Board’s decision. Under Delaware law, if a nominee who was not already serving as a director is not elected by a majority of votes cast by stockholders at an annual meeting, such nominee would not become a director.

|  | The nominees have been recommended to the Board by the Nominating and Corporate Governance Committee of the Board. The Board recommends that you vote “FOR” the election of each of the twelve nominees as described under “Director Nominees.”

Director Independence

The Board and its Nominating and Corporate Governance Committee have reviewed the standards of independence for directors established by applicable laws and regulations, including the listing standards of the New York Stock Exchange, and by the Company’s Corporate Governance Guidelines, and have reviewed and evaluated the relationships of directors with the Company and its management. Based upon this review and evaluation, the Board has determined that none of the non-employee members of the Board (that is, all directors but Mr. Costa) has or had a relationship with the Company or its management that would interfere with such director’s exercise of independent judgment, and that each non-employee member of the Board is an independent director. In addition, each non-employee member of the Board meets the heightened independence standards for our Audit, Compensation, and Nominating and Corporate Governance Committees. In making these determinations, the Nominating and Corporate Governance Committee and the Board reviewed and evaluated all direct and indirect transactions and relationships between the Company and the non-employee directors and their affiliates and immediate family members.

Director Nominations

The Nominating and Corporate Governance Committee is responsible for reviewing and recommending to the Board potential directors who possess the skills, knowledge, and understanding necessary to be valued members of the Board in order to assist it in successfully performing its role in corporate oversight and governance. The Nominating and Corporate Governance Committee considers not only an individual director’s or possible nominee’s qualities, performance, and professional responsibilities, but also the then-current composition of the Board and the challenges and needs of the Board as a whole in an effort to ensure that the Board is comprised of a diverse group of members who, individually and collectively, best serve the needs of the Company and its stockholders. In general, and in giving due consideration to the composition of the Board, the desired attributes of individual directors, including those of any nominees of stockholders, are as described under “Board Composition”.

The Nominating and Corporate Governance Committee will consider persons nominated by stockholders and recommend to the full Board whether such nominee should be included with the Board’s nominees for election by stockholders. Our Bylaws contain provisions that address the process (including the required information and deadlines) by which a stockholder or group of stockholders may nominate an individual for consideration by the Nominating and Corporate Governance Committee to stand for election at an annual meeting of stockholders. In addition, the proxy access provision in our Bylaws provides that, under certain circumstances, a stockholder, or a group of up to 20 stockholders, owning 3% or more of our outstanding common stock continuously for at least the previous three years may nominate and include director nominees constituting up to 20% of the number of directors then serving on the Board in the Company’s proxy materials, provided that such stockholder(s) and nominee(s) satisfy the disclosure and other requirements set forth in our Bylaws. In order to use this proxy access Bylaw provision, stockholders are required to hold shares until the date of the applicable annual meeting. For additional information on how stockholders may submit nominees for election to the Board, see “Additional Information about the Annual Meeting — What Are the Requirements for Nominations by Stockholders for Election to the Board of Directors and Stockholder Nomination Proxy Access?”.

Corporate Governance — Board Leadership Structure

Board Leadership Structure

|  | Mark J. Costa Board Chair |  |  |  |  |  | David W. Raisbeck Lead Director
The Chair of the Board provides leadership to the Board and works with the Board to define its structure and activities in the fulfillment of its responsibilities. The Company believes that the members of the Board possess considerable experience and unique knowledge of the challenges and opportunities the Company may face from time to time, and therefore are in the best position to evaluate the needs of the Company and how best to organize the capabilities of our directors and senior executives to meet those needs at any time. As a result, the Company believes that the decision as to who should serve as Chair and as Chief Executive Officer, and whether the offices should be combined or separate, is properly the responsibility of the Board, to be exercised from time to time in appropriate consideration of then-existing facts and circumstances. Our Corporate Governance Guidelines provide the Board the flexibility to determine whether or not the separation or combination of the Chair and Chief Executive Officer offices is in the best interests of the Company. Chief Executive Officer and director Mark J. Costa has served as Chair since 2014. The Board has determined that this is the most efficient manner to facilitate effective communication between management and the Board and provide strong and consistent leadership as well as a unified voice for the Company. In addition, the Board believes that combining the roles of Chair and Chief Executive Officer helps ensure that the Chief Executive Officer understands and can effectively and efficiently manage the implementation of the recommendations and decisions of the Board. |  |  |  | In order to ensure effective, independent leadership on the Board and appropriate oversight of management, Eastman’s Bylaws and Corporate Governance Guidelines require an independent Lead Director when the same person holds the Chief Executive Officer and Chair positions or if the Chair is not otherwise independent. The Lead Director’s responsibilities, which are described in more detail in the Company’s Corporate Governance Guidelines, include: •  calling, setting agendas for, and presiding over executive sessions of the non-employee, independent directors at each regularly scheduled meeting of the Board, or at such other times as the non-employee, independent directors may determine; •  calling special meetings of the full Board or the non-employee, independent directors; •  presiding over Board meetings in the absence of the Board Chair; •  collaborating and consulting with the Chair and Chief Executive Officer, the Corporate Secretary, and other senior management concerning and approving or directing the approval of agendas, schedules, and materials for Board meetings; •  acting as a liaison between the independent directors and the Chair; and •  being available with the Chair for consultation and direct communication with stockholders.

The Board has an Audit Committee, a Compensation and Management Development Committee, a Nominating and Corporate Governance Committee, an Environmental, Safety and Sustainability Committee, and a Finance Committee. All committee members are non-employee, independent directors.

In addition to the Lead Director providing independent leadership of the Board, certain key Company functions have completely independent Board oversight. As described below, the Finance Committee and the Environmental, Safety and Sustainability Committee each consists of all the non-employee, independent directors and is chaired by an independent director. Under this hybrid leadership structure with two Board “committees of the whole,” the Company’s financial and financing functions and health, safety, environmental, security, and sustainability functions are overseen by all of the independent directors under independent director leadership.

We believe that the foregoing structure, policies, and practices, when combined with the Company’s other governance policies, procedures, and practices described below, provide appropriate oversight, discussion, and evaluation of decisions and direction from the Board.

Corporate Governance — Committee Reports

Committee Reports

Audit Committee Report

On behalf of the Board, the Audit Committee oversees the Company’s financial reporting process and its internal control over financial reporting and related disclosure controls and procedures, areas for which management has the primary responsibility. The independent registered public accounting firm is responsible for expressing an opinion on the conformity of the Company’s audited financial statements with accounting principles generally accepted in the United States and for issuing its report on the Company’s internal control over financial reporting. All audit and non-audit services provided to the Company by the independent registered public accounting firm are pre-approved by the Audit Committee or by the Chair of the Audit Committee pursuant to delegated authority, and the Audit Committee considers the compatibility of such non-audit services with the accounting firm’s independence. At the beginning of the year, the Audit Committee reviewed and approved all known audit and non-audit services and fees to be provided by and paid to PricewaterhouseCoopers LLP, the Company’s independent registered public accounting firm. During the year, specific audit and non-audit services or fees not previously approved by the Audit Committee were approved in advance by the Audit Committee or by the Chair of the Audit Committee pursuant to delegated authority.

The Audit Committee evaluates the performance of the independent registered public accounting firm, including the senior audit engagement team, each year and determines whether to reengage the current independent registered public accounting firm or consider other independent registered public accounting firms. In doing so, the Audit Committee considers the quality and efficiency of the services provided by the firm, the firm’s global capabilities, and the firm’s technical expertise, tenure as the Company’s independent registered public accounting firm, and knowledge of the Company’s global operations and industry. Based on this evaluation, the Audit Committee decided to retain PricewaterhouseCoopers LLP to serve as independent registered public accounting firm for the year ending December 31, 2023. Although the Audit Committee has the sole authority to appoint the independent registered public accounting firm, the Audit Committee has continued its long-standing practice of recommending that the Board ask stockholders to ratify the appointment of the independent registered public accounting firm at the 2023 Annual Meeting (see “Item 2 — Ratification of Appointment of Independent Registered Public Accounting Firm”).

Of the Audit Committee’s nine meetings during 2022, five were regular meetings that included separate private (or “executive”) sessions of the Audit Committee with the Company’s independent registered public accounting firm and with Company management, including the Director of Corporate Audit Services, the Chief Legal Officer, the Chief Financial Officer, the Chief Accounting Officer, the Corporate Controller, the Director of Corporate Compliance, the Chief Information Officer, and other financial and legal management employees, and among the Audit Committee members themselves. These executive sessions included discussion of specific financial management, legal, accounting, auditing, internal and disclosure controls, corporate compliance, and risk management matters. As part of its oversight of the Company’s risk management process, the Audit Committee reviewed and discussed management’s risk assessment and risk management program, including individual areas of risk and the overall risk management process. See “Risk Oversight” later in this proxy statement. The Audit Committee also met with the Chief Legal Officer and the Director of Corporate Compliance to discuss the effectiveness of the Company’s compliance program and received regular corporate compliance program status reports and updates.

Four of the Audit Committee’s meetings included review of the Company’s planned public disclosures of quarterly financial results. These meetings included review with management and the independent registered public accounting firm of the financial statements and management’s discussion and analysis of financial condition and results of operations disclosures in the Company’s Annual Report on Form 10-K and Quarterly Reports on Form 10-Q filings prior to filing with the SEC and of matters relating to the Company’s internal control over financial reporting and disclosure controls and procedures for such filings.

Corporate Governance — Committee Reports

Numerous other informal meetings and communications among the Chair, various Audit Committee members, PricewaterhouseCoopers LLP, the Director of Corporate Audit Services, the Chief Information Officer, and other members of the Company’s management also occurred. The agenda for each of the Audit Committee’s meetings is established by the Audit Committee Chair.

Throughout the year, the Audit Committee reviewed with the Company’s financial management, PricewaterhouseCoopers LLP, and the Director of Corporate Audit Services the overall audit scope and plans, the results of internal and external audit examinations, evaluations by management and the independent registered public accounting firm of the Company’s internal controls over financial reporting, and the quality of the Company’s financial reporting.

Management has reviewed and discussed the audited financial statements and related disclosures in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022, with the Audit Committee. This review and discussion included the quality of accounting principles, the reasonableness of the significant accounting judgments and estimates, the clarity of disclosures in and concerning the financial statements, and the internal controls and disclosure controls and procedures that support management’s accounting and disclosure judgments and the certifications of the Chief Executive Officer and the Chief Financial Officer that the financial statements of the Company fairly present, in all material respects, the financial condition, results of operations, and cash flows of the Company.

In its meetings with representatives of PricewaterhouseCoopers LLP, the Audit Committee asked them to address, and discussed their responses to, questions relevant to the Audit Committee’s oversight. These discussions included significant accounting judgments or estimates made by management in preparing the financial statements, fair presentation to investors in the financial statements of the Company’s financial position and performance in accordance with generally accepted accounting principles and SEC disclosure requirements, and implementation of internal controls and internal audit procedures that are appropriate for the Company.

The Audit Committee also discussed with PricewaterhouseCoopers LLP the matters required to be discussed by the standards of the Public Company Accounting Oversight Board (the “PCAOB”). The Audit Committee has received from PricewaterhouseCoopers LLP the written disclosures and the letter required by applicable requirements of the PCAOB regarding the independent registered public accounting firm’s communications with the Audit Committee concerning independence, and discussed with them their independence from the Company and its management. In addition, the Audit Committee has received written materials addressing PricewaterhouseCoopers LLP internal quality control procedures.

In reliance on these reviews and discussions and the reports of PricewaterhouseCoopers LLP, the Audit Committee has recommended to the Board, and the Board has approved, that the audited financial statements be included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022, filed with the SEC.

Corporate Governance — Compensation Consultant

Compensation Consultant

The Compensation Committee has directly engaged Aon’s Human Capital Solutions practice a division of Aon plc (“Aon”) as its external compensation consultant. Aon reports to, and receives its direction from, the Compensation Committee, and a representative of Aon attends each meeting of the Compensation Committee as its advisor. Aon provides the Compensation Committee with third-party survey information used in setting short- and long-term compensation levels, perspective on emerging compensation issues and trends, and expertise in incentive compensation structure, terms, and design. Aon also provides such services to the Nominating and Corporate Governance Committee for its recommendations to the Board regarding non-employee director compensation. Any other services provided by Aon and its affiliates to Eastman are approved by the Compensation Committee. Company management also uses the services of several other outside firms for compensation analysis, third-party surveys, and management pay research and analysis. None of these other firms provide any consulting services to the Compensation Committee or to the Nominating and Corporate Governance Committee.

In reviewing Aon’s performance in 2022 and considering its continued engagement for 2023, the Compensation Committee evaluated Aon’s independence from Company management and any conflicts of interest in accordance with applicable New York Stock Exchange listing requirements. The Compensation Committee considered Aon’s provision of other services to the Company, the fees paid by the Company to Aon as a percentage of the firm’s total revenue, Aon’s policies and procedures to prevent conflicts of interest, and the confirmation by Aon that it and its representatives have no business or personal relationship with any member of the Compensation Committee, do not own any stock of the Company, and have no business or personal relationship with any executive officer of the Company. The Compensation Committee concluded that Aon is independent of the Compensation Committee and of Company management and has no conflicts of interest in its performance of services to the Compensation Committee.

Key Areas of Board Oversight

Corporate Strategy and Business Performance

With the leadership of the Board Chair and Chief Executive Officer, the Board actively oversees development, implementation, and results of executive management’s corporate growth and business strategy, including the current innovation-driven growth model. Corporate strategy and business and financial results, expectations, prospects, and opportunities are reviewed and discussed with the Chief Executive Officer and senior management throughout the year at each Board meeting and at meetings of the Audit, Compensation and Management Development, Finance, and Environmental, Safety and Sustainability Committees, including in separate private (or “executive”) sessions with the Chief Executive Officer and other individual executive and senior managers.

Risk Oversight

The Board maintains oversight responsibility for the management of the Company’s risks, and oversees an enterprise-wide approach to risk management, designed to provide a holistic view of organizational objectives, including strategic objectives, to improve long-term organizational performance, to prioritize and manage identified risks, and to enhance stockholder value. A fundamental part of risk management is not only understanding the risks the Company faces and what steps management is taking to manage those risks, but also understanding what level of risk is appropriate for the Company. The full Board reviews with management its process for managing enterprise risk. Additionally, the Audit Committee is charged with overseeing our risk assessment and management process each year to: (i) ensure that management has instituted processes to identify major risks and has developed plans to manage such risks; and (ii) review with management the most significant risks identified and management’s plans for addressing and mitigating the potential effects of such risks. During the Company’s risk management review process, risk is assessed throughout our entire

Corporate Governance — Key Areas of Board Oversight

business, and is reported to a management corporate risk committee comprised of members of our various business units and control functions. Risks that are identified as “high-level” risks are reported to the Audit Committee and thereafter assigned, as appropriate, to various of the Board’s Committees, or to the Board as a whole, for further review, analysis, and development of appropriate plans for management and mitigation.

While the Board maintains the ultimate oversight responsibility for risk management and for oversight of certain specific risks, each of the various Committees of the Board have been assigned responsibility for risk management oversight of specific identified areas. In particular, and in addition to its responsibility to conduct an annual assessment of the risk management process and report its findings to the Board, the Audit Committee maintains responsibility for overseeing risks related to the Company’s financial reporting, audit process, internal controls over financial reporting and disclosure controls and procedures. In addition to these risks, the Audit Committee is also responsible for the oversight of cybersecurity risk, mitigation strategies (including review of the Company’s cyber insurance coverage) and the overall resiliency of the Company’s technology infrastructure. As part of its risk oversight responsibilities, the Audit Committee periodically reviews third-party assessments of information security standards, any incidents that could have a material impact on the Company’s network, and potential cybersecurity risk disclosures. In February 2023, Linnie Haynesworth joined the Board and the Audit Committee. She is a recognized expert in cybersecurity governance matters, as she previously served as Sector Vice President and General Manager of the Cyber and Intelligence Mission Solutions Division for Northrop Grumman Corporation’s Mission Systems Sector.

The Finance Committee has oversight responsibility related to the Company’s financial position and financing activities, including such areas as capital structure, raw material and energy costs, availability, and price volatility and hedging, large capital projects, pension obligations and funding, and acquisitions, divestitures, and joint ventures. The Environmental, Safety and Sustainability Committee assists the Board in fulfilling its oversight responsibility with respect to health, safety, environmental, security, public policy and political activities, and the Company’s sustainability strategy, GHG emission reduction goals and related climate disclosures. In addition, in setting compensation, the Compensation Committee endeavors to develop a program of incentives that encourage an appropriate level of risk-taking behavior consistent with the Company’s long-term business strategy and also reviews the employee development as part of the Company’s succession planning process. Finally, the Nominating and Corporate Governance Committee conducts an annual assessment of nominees to our Board and is charged with developing and recommending to the Board corporate governance principles and policies and Board Committees structure, leadership, and membership, including those related to, affecting, or concerning the Board’s and its Committees’ risk oversight.

Human Capital and Company Culture

The Board believes that effective attraction, development, and retention of our employees (or “human capital”), including workforce and management development, inclusion and diversity initiatives, succession planning, corporate culture, and compensation and benefits, are vital to the success of Eastman’s innovation-driven growth strategy. The Board regularly evaluates Eastman’s culture and monitors leadership quality, employee morale, and talent development through one-on-one meetings with key senior managers, senior manager presentations at Board and Committees meetings, and other meetings before and after Board and Committees meetings. Additional detail around human capital management can be found within the pages of the Company’s Annual Report on Form 10-K for the year ended December 31, 2022 (the “2022 Form 10-K”).

Succession Planning

The Board oversees workforce and senior management development primarily through its Compensation Committee. In its oversight of senior management evaluation, development and compensation, as well as its evaluation of executive officer performance and determination of executive compensation, the Compensation Committee regularly reviews with management and the Board employee composition, talent, diversity, and senior management development and succession plans, and the Board regularly reviews management and employee I&D programs and initiatives. In addition, the Chief Executive Officer regularly reviews and discusses privately with the Board executive succession plans, and the Lead Director and the Chair of the Compensation Committee at least annually privately review Chief Executive Officer and senior management succession plans with the independent directors.

Sustainability

Board of Directors

At the highest level, the Board of Directors provides oversight to our growth strategy, which is founded in a model of innovating for a sustainable future. Chaired by Julie F. Holder, the Environmental, Safety and Sustainability Committee is a Board Committee of all the independent directors that oversees our sustainability strategy, initiatives, and performance. Eastman’s Chief Sustainability Officer meets regularly with the Environmental, Safety and Sustainability Committee to review sustainability initiatives and progress.

Sustainability Council and Executive Oversight

Eastman’s Sustainability Council is composed of executive team members and senior leaders to drive alignment of our commitments across the enterprise and address emerging opportunities. Eastman’s Chief Executive Officer and Board Chair has executive responsibility for the Company’s strategy and performance, including sustainability performance as it aligns to the corporate strategy. Sustainability goals are included in our Chief Executive Officer’s annual personal performance commitments, including environmental performance and safety.

Eastman’s three sustainability sub-councils and their working groups proactively identify emerging issues, assess options, and make recommendations. The membership of the sub-councils is strategically selected for organizational representation and subject matter expertise to catalyze action on important issues.

The Company’s sustainability program, and its relationship to our strategy for innovative growth, is described in our annual Sustainability Report on the Eastman website.

Corporate Governance — Board Practices, Processes, and Policies

Board Practices, Processes, and Policies

Board Meetings and Attendance

The Board held seven meetings during 2022. Each Board meeting included one or more “executive sessions” led by the Lead Director without the Chief Executive Officer or other management. Each director attended at least 75% of the aggregate of the total number of meetings of the Board and the total number of meetings held by all Committees of the Board on which he or she served. The Board meets immediately before each annual meeting of stockholders, and the directors in attendance at such Board meeting attend the annual meeting of stockholders. All directors then serving on the Board attended the 2022 virtual Annual Meeting of Stockholders.

Board and Committees Performance Evaluations

Board and Committee evaluations play an important role in ensuring that the Board and its Committees’ function effectively and in the best interest of our stockholders. Each year the Board and its Committees evaluates its own performance against the requirements of the Corporate Governance Guidelines and the applicable Committee charter. The self-evaluation process seeks to identify specific areas, if any, that need improvement or strengthening in order to increase the effectiveness of the Board, its members and its Committees. The Lead Director and the Chair of the Nominating and Corporate Governance Committee annually review and agree on the evaluation process. In 2022, the Board conducted a formal peer assessment. The assessment was designed to ensure that the Board possess the independence, diversity, skills and expertise to provide strong and effective oversight and ensure that the Board functions effectively and in the best interest of our stockholders. The assessment was conducted by an independent external facilitator who encouraged participants to be introspective about themselves, their fellow Board members, and the operations of the Board and its Committees.

1. Process Initiated |  | The Lead Director and the Chair of the Nominating and Corporate Governance Committee initiated the evaluation process with the assistance of an independent third-party.
2. Survey |  | Each director completed an electronic survey with survey questions centered around five core areas of responsibility and oversight: (i) Board composition; (ii) talent oversight and CEO succession; (iii) Board processes and operations; (iv) strategy oversight; and (v) risk management.
3. Interviews |  | The facilitator conducted individual interviews with each director eliciting candid feedback from the participants in an unrestrained and congenial setting.
4. Findings |  | The facilitator compiled all the quantitative and qualitative information, benchmarked the Board against national standards and research and provided a thorough and comprehensive written narrative report. The results of the assessment were reviewed with the Lead Director, Chair of the Nominating and Corporate Governance Committee and Chair of the Board.
5. Feedback Incorporated |  | The Lead Director shared the results with the full Board and reviewed any recommended actions aligning on improvement opportunities for implementation. As a final step, the facilitator then conducted one-on-one conversations with each individual director.

Individual directors are evaluated by the Nominating and Corporate Governance Committee as part of consideration for nomination for election or re-election. This evaluation is conducted by the Lead Director and the Nominating and Corporate Governance Committee.

Transactions with Directors, Executive Officers, and Related Persons

At least annually the Board reviews and evaluates all current and recent past transactions involving the Company in which non-employee directors and their affiliates (including immediate family members and other firms, corporations, or entities with which the director has a relationship) have or had a direct or indirect interest. The Board also reviews any such transactions and relationships in which executive officers of the Company or members of their immediate families have or had an interest. Written Company policies require approval by the Board (in the case of the Chief Executive Officer) or senior management (in the case of all other employees) of each Company transaction in which an employee has a direct or indirect financial or other personal interest, and restrict reporting relationships between immediate family member employees.

2023 Proxy Statement 39

Corporate Governance — Board Practices, Processes, and Policies

In the most recent review, the Board considered purchases and sales of products and services in the ordinary course of business to and from companies of which non-employee directors are or were officers. Each such transaction was below the thresholds of the categorical standards listed above and determined by the Board not to be a material transaction or relationship.

The Board also reviewed employment by the Company of four immediate family members of executive officers. One of the immediate family members’ compensation was below the relevant dollar threshold of applicable SEC rules for disclosure in this proxy statement, and the terms of such employment, including compensation and benefits, were in all respects according to standard Company employment policies and practices. This executive’s immediate family members worked in an organization that was not in the executive’s line of management or the executive had no direct reporting relationship with his immediate family member, and the executive made no, and will not make any, hiring, compensation, promotion, or evaluation decisions regarding his immediately family member.

Two immediate family members (husband and brother-in-law) of Michelle R. Stewart, the Company’s Vice President, Corporate Controller and Chief Accounting Officer (principal accounting officer) are employed by Eastman. The spouse of Travis Smith, Senior Vice President, Additives and Functional Products, is also employed by the Company. Each of these three individuals are employed in non-executive officer positions and each received total compensation for 2022 of less than $275,000. The terms of the employment of Ms. Stewart’s and Mr. Smith’s immediate family members, including compensation and benefits, were in all respects according to standard Company employment policies and practices applicable to professional employees with comparable qualifications and responsibilities and holding similar positions. None of these three individuals work in the same internal organization, nor are they in the line of management, of their respective family member executive. In each case, neither Ms. Stewart nor Mr. Smith made, and will not make, any hiring, compensation, promotion, or evaluation decisions regarding their family members. Consistent with our related person transaction policy as described above, our Nominating and Corporate Governance Committee and Board reviewed this matter.

Board Corporate Governance Guidelines and Committees Charters; Codes of Business Conduct and Ethics

The Nominating and Corporate Governance Committee of the Board periodically reviews and assesses the Board’s Corporate Governance Guidelines and governance practices, and each Committee reviews and assesses its Charter, and recommends any changes to the Board. We make available free of charge, through the “Investors — Governance” section of the Eastman website, the Board’s Corporate Governance Guidelines, the Charters of each of the Committees of the Board, and Codes of Business Conduct and Ethics for our directors, officers, and employees. Such materials are also available in print upon written request of any stockholder to Eastman Chemical Company, P.O. Box 431, Kingsport, Tennessee 37662-0431, Attention: Investor Relations.

Communications to the Board of Directors and Investor Engagement

The Board believes that communication and engagement with the Company’s stockholders and other interested parties is an important component of the Company’s corporate governance practices. We have adopted a Board Stockholder Communication and Engagement Policy to facilitate communication between stockholders and other interested parties and the Board. Stockholders and other interested parties may send communications to the Board, any individual director, or the independent directors as a group in writing by mail or email to: Board of Directors, Eastman Chemical Company, c/o Corporate Secretary, P.O. Box 1976, Kingsport, Tennessee 37662-1976, email: corpsecy@eastman.com and leaddirector@eastman.com. Stockholders should indicate in the “ATTN:” line of the envelope or the subject line of the email, as applicable, whether the communication is directed to the Board, an individual director, or the independent directors as a group. The Board Stockholder Communication and Engagement Policy is available on the “Investors — Governance” section of the Company’s website.

In addition, to create opportunities for directors and management to listen to the views of the Company’s stockholders and to provide explanation of the Company’s publicly available material information, from time to time directors and certain senior members of management meet with certain stockholders of the Company.

Director Compensation

DIRECTOR COMPENSATION

Compensation Philosophy

Director compensation is determined by the Board based upon the recommendation of the Nominating and Corporate Governance Committee and its compensation consultant. The Board uses a combination of cash and stock-based compensation to attract and retain qualified candidates to serve as directors. In setting the compensation of non-employee directors, the Nominating and Corporate Governance Committee and the Board consider the significant amount of time that the Board and its Committees are expected to expend, the skills, knowledge, and understanding needed for service on the Board, and the types and amounts of director pay of similar public companies (including the compensation peer comparison companies discussed under Compensation Discussion and Analysis later in this proxy statement). Cash retainers and event fees are paid in two semi-annual payments.

The Nominating and Corporate Governance Committee and the Board annually review non-employee director compensation, and the Board, upon the recommendation of the Nominating and Corporate Governance Committee, has from time to time changed the amounts and forms of director pay to make the value of total non-employee director compensation closer to that of peer director compensation benchmarking companies. Following an annual review of non-employee director compensation, the Board increased the annual director retainer, the annual restricted stock award, and the annual Audit Committee Chair retainer effective January 1, 2022, in each case to make the value of total non-employee director compensation closer to that of peer director compensation. In 2022, the annual director retainer fee increased to $120,000, the annual Audit Committee Chair retainer increased to $25,000 and the value of the annual restricted stock award increased to $110,000. The Nominating and Corporate Governance Committee in 2022 concluded that non-employee director total pay was in line with external market comparisons, and accordingly the Board made no changes to non-employee director compensation for 2023.

2022 Director Compensation

Director Compensation — Directors’ Deferred Compensation Plan

Restricted Stock Awards

Each non-employee director receives an annual award of restricted shares of common stock having a fair market value equal to $110,000 (with the number of restricted shares awarded rounded up in the case of fractional shares) made on the date of the Annual Meeting of Stockholders.

In addition, upon initial election to the Board, a director receives a one-time award of restricted shares having a fair value equal to $10,000 (with the number of restricted shares awarded rounded up in the case of fractional shares).

Such awards are made under the Director Stock Compensation Subplan of the 2021 Omnibus Stock Compensation Plan (the “DSCS”).

| (i) | the next Annual Meeting of Stockholders in the case of the annual awards and the one-year anniversary of the one-time awards (provided the grantee is still a director),

| (ii) | death, disability, or resignation due to attaining retirement age or another approved reason during the restricted period, or

| (iii) | departure from the Board at the end of the term of service to which elected (in the case of the annual awards) or failure to be re-elected as a director during the one-year term after the grant (in the case of the one-time awards).

During the restricted period, the director has all of the rights of a stockholder with respect to the restricted shares (other than the right to transfer the shares), including voting and dividend rights. The DSCS contains provisions regarding the treatment of restricted shares in the event of a “change in control” (as defined in the DSCS, generally circumstances in which the Company is acquired by another entity or its controlling ownership is changed). In such event, all outstanding restricted shares would immediately vest and become transferable, and would be valued and cashed out on the basis of the change in control price as soon as practicable, but in no event more than 90 days after the change in control. The Nominating and Corporate Governance Committee has the discretion, even if a change in control event will occur, to determine that immediate vesting of restricted shares under the DSCS should not occur for that event and that the restricted shares will not become fully vested when that event occurs.

Directors’ Deferred Compensation Plan

The Directors’ Deferred Compensation Plan (the “DDCP”) is an unfunded, nonqualified, deferred compensation plan under which each non-employee director may elect to defer compensation received as a director until he or she ceases to serve as a director. Non-employee directors may make an annual advance irrevocable election to defer compensation for services to be rendered the following year. Compensation that may be deferred is (i) all or a portion of cash compensation for service as a director, including retainer and “event” fees and (ii) the annual restricted stock award for service as a director.

If a director elects to defer the annual restricted stock award, the value of the award is first converted to an unvested deferred cash equivalent amount in the Eastman phantom stock account of the DDCP which is subject to forfeiture until it vests if the director is still serving as a director immediately prior to the election of directors at the next annual meeting of stockholders, after which it remains deferred until the end of service as a director.

In addition, each non-employee director receives a non-elective annual deferral of $60,000 that is initially deferred into the director’s Eastman phantom stock account of the DDCP. Directors may elect to credit deferred compensation accounts in the DDCP to individual hypothetical investment alternatives, including Eastman phantom stock. Upon completion of service as a director, the value of the director’s DDCP account is paid, in cash, in a single lump sum or in up to ten annual installments as elected in advance by the director.

For 2022, there were no preferential or above-market earnings on amounts in individual hypothetical investment accounts (defined as appreciation in value and dividend equivalents earned at a rate higher than appreciation in value and dividends on the underlying common stock or interest on amounts deferred at a rate exceeding 120% of the federal long-term rate).

Eastman does not have a director pension plan.

ITEM 2 — Ratification of Appointment of

Independent Registered Public Accounting Firm

The Audit Committee of the Board has appointed PricewaterhouseCoopers LLP to serve as the Company’s independent registered public accounting firm for the year ending December 31, 2023.

PricewaterhouseCoopers LLP also served as the Company’s independent registered public accounting firm for the years ended December 31, 2021 and 2022, and has billed the Company the following amounts for fees and related expenses for professional services rendered during 2021 and 2022:

(IN THOUSANDS) |  | For the Year Ended December 31, 2021 |  | For the Year Ended December 31, 2022
Audit Fees and Expenses(1) |  |  | $ | 5,540 |  |  |  | $ | 5,455 |
Audit-Related Fees and Expenses(2) |  |  |  | 3,100 |  |  |  |  | 95 |
Tax Fees and Expenses(3) |  |  |  | 4,554 |  |  |  |  | 3,808 |
All Other Fees and Expenses(4) |  |  |  | 5 |  |  |  |  | 195 |
Total |  |  | $ | 13,199 |  |  |  | $ | 9,553 |

(1) | Audit fees and expenses represent fees and expenses for professional services rendered for the audits of the consolidated financial statements of the Company (including the audit of internal controls over financial reporting) and review of financial statements included in quarterly reports, statutory and subsidiary audits, issuance of comfort letters, and assistance with review of documents filed with the SEC.

(2) | Audit-related fees and expenses consist primarily of assurance and related services, including audit and related procedures for possible mergers, acquisitions, and divestitures, and consultations concerning application of and compliance with financial accounting and reporting standards. In addition, certain of the Company’s employee benefit plans were billed for fees and related expenses of $65,000 for audits of their plan financial statements by PricewaterhouseCoopers LLP during 2021 and 2022. The decrease in fees in 2022 from 2021 was primarily due to audit-related services provided in relation to the divestitures of the Company’s tire additives business, and adhesives resins business, which services were incurred in 2021.

(3) | Tax fees and expenses consist primarily of services related to domestic and international tax planning, tax compliance, including preparation of tax returns and claims for refunds, tax advice, assistance with respect to tax audits, and requests for rulings for technical advice from tax authorities.

(4) | All other fees and expenses principally include ESG attestation services, research tools and software access licenses.

As described under “Committee Reports — Audit Committee Report” earlier in this proxy statement, all audit and non-audit services provided to the Company by PricewaterhouseCoopers LLP were pre-approved by the Audit Committee or by the Chair of the Audit Committee pursuant to delegated authority.

The stockholders are being asked to ratify the Audit Committee’s appointment of PricewaterhouseCoopers LLP. If the stockholders fail to ratify this appointment, the Audit Committee may, but is not required to, reconsider whether to retain that firm. Even if the appointment is ratified, the Audit Committee in its discretion may direct the appointment of a different accounting firm at any time during the year if it determines that such a change would be in the best interests of the Company and its stockholders.

A representative of PricewaterhouseCoopers LLP is expected to attend the 2023 Annual Meeting and will have the opportunity to make a statement on behalf of the firm if he desires to do so. The representative is also expected to be available to respond to appropriate questions from stockholders.

|  |  |  | The Board of Directors recommends that you vote “FOR” ratification of the appointment of PricewaterhouseCoopers LLP as Eastman’s independent registered public accounting firm.

EXECUTIVE COMPENSATION

Compensation Discussion and Analysis

This “Compensation Discussion and Analysis” (“CD&A”) provides context for the executive compensation information detailed in the tables and narrative in the following sections of this proxy statement. The Compensation and Management Development Committee (the “Compensation Committee”) establishes and oversees the administration of the policies, programs, and procedures for evaluating, developing, and compensating our senior management, and determines the components, structure, forms, terms, and amounts of the compensation of our executive officers. What follows is a summary of compensation philosophy and objectives for executive officers, the relationship of corporate performance to executive compensation, and the basis for the compensation of executive officers. This CD&A provides compensation information for our named executive officers (“NEO”), including our Chief Executive Officer (“CEO”), Mark J. Costa, our Chief Financial Officer (“CFO”), William T. McLain, Jr. and the three other most highly compensated executive officers who were serving as executive officers on December 31, 2022, Brad A. Lich, Stephen G. Crawford and Perry Stuckey III. Mr. Stuckey separated from the Company without cause effective January 1, 2023, pursuant to an involuntary separation agreement. For a discussion of the payments received by Mr. Stuckey under this agreement, see the “Summary Compensation Table.”

Executive Compensation — Compensation Discussion and Analysis

EXECUTIVE SUMMARY

In 2022, the Company faced a number of unique challenges - particularly in the second half of the year. The first and second quarter results reflected strong end-market demand and the ability to offset raw material increases through aggressive pricing actions. However, our volume growth was also limited by operational and supply chain disruptions, which prevented us from taking full advantage of the strong demand environment. As we moved into the second half of the year, significant inflationary pressures, and rising interest rates resulted in weakening economic conditions and softening demand. In the fourth quarter, demand across markets and regions slowed and customer destocking became more broad-based and severe, causing a significant decline in volume. A strong U.S. dollar was also a substantial headwind throughout the year.

Despite the significant challenges in the fourth quarter and throughout the year, the Company’s strong pricing efforts, progress on innovation-driven growth, operational processes and safety, and continued focus on cost management are expected to help position Eastman for growth going forward. During the year, we made significant progress on our circular platform highlighted by our plans to build three world-scale, material-to-material molecular recycling facilities. The first of these plants is located at our global headquarters in Kingsport, Tennessee where we expect to begin commissioning and start-up activities by summer 2023. In 2022, we announced plans to invest in a second molecular recycling facility in Normandy, France that will use Eastman’s polyester renewal technology to recycle up to 110,000 metric tons annually of hard-to-recycle plastic waste. We also reached a definitive supply agreement in 2022 for a planned third molecular recycling facility, which will be located in the United States. The advancement of these three projects reinforces our commitment towards making a significant contribution to the plastic waste and climate crises.

For 2022, Eastman’s sales revenue increased 1% to $10.58 billion, earnings before interest and taxes (“EBIT”) decreased nearly 10% to $1.16 billion and adjusted EBIT decreased 18% to $1.34 billion. The Company generated operating cash flow (“OCF”) of $975 million in 2022, and returned approximately $1.4 billion to stockholders through share repurchases and dividends. In addition, the Company’s innovation and market development platform enabled the Company to close more than $550 million of new business in 2022. Looking ahead, we believe the Company is well-positioned to capitalize on its growth strategy, as we expect the momentum from our innovation programs to further accelerate as leading brands continue to adopt our sustainable product offerings. See Annex A of this proxy statement for reconciliation of financial measures under accounting principles generally accepted in the United States (“GAAP”) to non-GAAP financial measures, description of excluded items, and related information.

As with past years, the Compensation Committee designed and implemented incentive compensation programs that support the Company’s long-term growth strategy and align payouts with Company performance. The Compensation Committee’s payout decisions with respect to the 2022 annual cash incentive compensation program and the 2020-2022 performance share awards, as detailed in the following pages, reflect a strong alignment between pay and performance.

Strong Pay and Performance Alignment
The Compensation Committee believes that a significant portion of our executives’ total compensation should be “at risk” and performance-based. Consistent with this pay-for-performance philosophy and compensation program design, 100% of the incentive compensation approved by the Compensation Committee for the NEOs was performance-based and at-risk. At-risk, performance-based compensation is only earned if the threshold level of targeted business and individual performance is met. The Compensation Committee believes it is also important to an appropriate balance between the short-term and long-term focus of executives, and in the types of performance incented and risks encouraged, as well as to align their interests with those of stockholders, by providing a meaningful portion of their compensation in the form of equity-based pay.

2023 Proxy Statement 47

Executive Compensation — Compensation Discussion and Analysis

Reflecting the Company’s strong pay for performance structure, the compensation earned by, or accrued for, the CEO and other NEOs for 2022 was negatively impacted by: (i) performance against the financial targets set under the 2022 annual incentive compensation program; and (ii) year-end stock price on the estimated worth of the performance share awards and stock options granted in February 2022. The table below shows the compensation earned by or accrued for the CEO for 2022, and the estimated worth of the performance shares and stock options granted in 2022 as of year-end.

|  | 2022 CEO Earned or Accrued Pay1 |  | Summary Compensation Table
Actual Base Salary Paid |  |  | $ | 1,331,575 |  |  |  | $ | 1,331,575 |
Actual Non-Equity Incentive Plan Paid |  |  | $ | 0 |  |  |  | $ | 0 |
2022 Performance Share Awards2 |  |  | $ | 4,918,080 |  |  |  | $ | 11,996,462 |
2022 Option Grant2,3 |  |  | $ | 0 |  |  |  | $ | 2,825,667 |
Change in Pension Value and Nonqualified Deferred Compensation Earnings |  |  | $ | 305,653 |  |  |  | $ | 305,653 |
All Other Compensation |  |  | $ | 608,774 |  |  |  | $ | 608,774 |
Total |  |  | $ | 7,164,082 |  |  |  | $ | 17,068,131 |

1. Differences in Reported Pay and Earned or Accrued Pay. The “Total” amount that is reported in the Summary Compensation Table for the CEO (and each NEO) is a combination of actual amounts paid or earned for the year (base salary, annual incentive pay awards, Company contributions to defined contribution plans, and perquisites and personal benefits) and estimated values of appreciation, payouts, and payments in future years using accounting and actuarial financial models to estimate possible future payments, all calculated in accordance with SEC rules. For the 2022 CEO earned or accrued pay, (a) the amount listed for the 2022 Performance Share Awards is the estimated worth of possible future payout of performance shares awarded in 2022, as described in footnote 2 and (b) the amount listed for the 2022 Option Grant is the difference in the per share option exercise price and the closing price on December 30, 2022, as described in footnote 3.

2. The estimated worth of the 2022 Performance Share Awards is based on target performance of such award through 2022 and assuming a market value equal to the closing price of the Company’s common stock on the New York Stock Exchange on December 30, 2022, the last trading day of 2022, which was $81.44.

3. The amount listed for the 2022 Option Grant is the difference in the per share option exercise price, which is $120.80 per share, and the closing price of the Company’s common stock on the New York Stock Exchange on December 30, 2022, the last trading day of 2022, which was $81.44. As such, Mr. Costa’s 2022 Option Grant is currently “underwater” (that is, the 2022 Option Grant has an exercise price above the market value of our shares).

Executive Compensation — Compensation Discussion and Analysis

Eastman Compensation Objectives, Philosophy and Program

Our Compensation Objectives. In designing the Company’s compensation program, the Compensation Committee’s primary objectives are to:

| • |  | leverage all major components of compensation to provide total target executive compensation levels that compete well in the marketplace;

| • |  | attract and retain highly-qualified executives by providing incentive opportunities for the attainment of the Company’s strategic business objectives and to achieve superior performance;

| • |  | provide appropriate short-term and long-term incentives to reward the attainment of short-term and long-term corporate and individual objectives consistent with corporate growth strategy and objectives;

| • |  | ensure performance targets are appropriately challenging and properly aligned with business strategy and stockholder interests; and

| • |  | maintain balance in the types of corporate and individual performance incented and the levels and types of risks managers are encouraged to evaluate and take.

Our Pay-for-Performance Compensation Philosophy. The Company’s strategy for growth from innovation, market development, and differentiated technologies leverages the capabilities of our employees while remaining committed to maintaining strong financial flexibility and liquidity to drive value for stakeholders. Our pay-for-performance compensation philosophy supports this strategy by stressing the importance of pay for:

| • |  | corporate and individual performance in meeting strategic and business goals for growth;

| • |  | innovative sustainable value creation; and

| • |  | financial strength and flexibility, while remaining able to meet changing employee, business, and market conditions.

The Compensation Committee has designed the executive compensation program to provide a strong linkage between executive pay and each executive’s performance using rigorous goal setting. Eastman recognizes employee contributions to business and financial performance through competitive total pay. For all employees, including executives, incentives and rewards are dependent on contributions to business objectives and successes. This includes:

| • |  | quantified corporate financial and business performance;

| • |  | Eastman’s commitment to recruiting and maintaining an inclusive and diverse workplace;

| • |  | promoting a strong culture of safety and sustainability; and

| • |  | creating long-term value for all stakeholders.

As described below, our executive compensation program has been designed so that a significant portion of compensation is based on performance measures that we believe are most relevant to our business strategy and significant to investors, including cumulative total shareholder return (“TSR”) and return on capital for multi-year periods, annual adjusted EBIT, OCF, and multi-year stock price appreciation.

Each year, the Compensation Committee, with the assistance of its independent compensation consultant, compares the relative mix of compensation components with those of peer benchmarking companies. The Compensation Committee does not have a fixed method for determining how the total mix of an executive officer’s total compensation should be allocated among these compensation components. Instead, the Compensation Committee uses a flexible approach to compensation to help us better achieve our business objectives from year to year and to attract and retain executive talent.

2023 Proxy Statement 49

Executive Compensation — Compensation Discussion and Analysis

Compensation Best Practices

Our compensation program incorporates the following practices and features:

What We Do |  |
|  | Oversight and decisions by a Compensation Committee comprised solely of independent directors with significant executive compensation and management experience who understand drivers of long-term corporate performance. |  |
|  | Use an independent compensation consultant to the Compensation Committee with no conflicts of interest. |  |
|  | Annual assessment by the Compensation Committee of potential risks associated with the compensation program. |  |
|  | Benchmark executive pay and overall program design and use competitive peer company data in making decisions about all components of pay. |  |
|  | Significant portion of pay based on corporate and individual performance. |  |
|  | Robust stock ownership expectations. |  |
|  | Executive pay recoupment (or “clawback”) policy. |  |
|  | “Double trigger” change-in-control vesting of outstanding stock-based pay awards. |  |
|  | Regular dialogue with investors and proxy advisory firms about executive pay program and practices. |  |

What We Don’t Do |  |
|  | Target a specific percentile of competitive peer company pay to set executive pay. |  |
|  | Reprice or change performance targets for stock options or other long-term stock-based incentive awards after those awards are granted. |  |
|  | Include value of equity awards in pension benefit calculations. |  |
|  | Allow pledging or hedging of Company stock by our executive officers. |  |
|  | “Gross-up” taxes for any imputed income on limited executive perquisites. |  |
|  | “Gross-up” tax payments, or accelerate equity vesting without termination following change-in-control, under limited change-in-control severance arrangements. |  |

Investor Engagement and Say-on-Pay Vote Results

Eastman has a history of actively engaging with our stockholders. We believe that strong corporate governance should include engagement with our stockholders. We solicit feedback on our corporate governance, executive compensation programs, disclosure practices, and environmental and social impact programs and goals. Investor feedback is shared with our Compensation Committee.

As described in “Item 3 — Advisory Approval of Executive Compensation”, at the 2023 Annual Meeting stockholders will again have the opportunity to indicate their views on the compensation of our named executive officers by an advisory “say-on-pay” vote. At the Company’s 2022 Annual Meeting, 92.4% of the votes cast on the say-on-pay proposal were voted in favor of the proposal. The Compensation Committee considered this vote result as general approval of the Company’s approach to executive compensation. In 2022, the Company continued its practice of investor engagement meeting with multiple investors and received very limited communications of concerns with current executive compensation program and practices. Accordingly, the Compensation Committee did not make any significant changes in the structure of the Company’s executive compensation program for 2022 as a result of the say-on-pay vote and subsequent investor communications.

The Compensation Committee will continue to consider the results of future say-on-pay proposals and other investor input, and other appropriate executive compensation and corporate governance developments, when making compensation decisions for our executive officers.

Executive Compensation — Compensation Discussion and Analysis

Analysis of Executive Compensation Risk

The balance of short-term and long-term compensation as tools to drive individual behaviors and risk management is carefully considered in the design and administration of the Company’s overall employee compensation programs. While a significant portion of our executive compensation is performance-based, we do not believe that our philosophy or objectives encourage excessive risk-taking. The Compensation Committee has focused our management compensation program on aligning compensation with the long-term interests of Eastman and its stockholders, and has designed the elements of our executive compensation program to discourage management decisions that could pose inappropriate long-term risks to the Company and its stockholders.

| • |  | The compensation of our executive officers is not overly-weighted toward short-term incentives. For instance, our CEO’s and the other NEOs’ target annual cash compensation opportunities for 2022, as a percentage of total annual target compensation, ranged from 18% for the CEO to an average of 30% for all other NEOs. Annual cash incentive pay awards are capped at 200% of an executive’s target award opportunity to protect against disproportionately large short-term incentives, and the Compensation Committee has broad discretion in determining the amount of the variable cash payout to each executive based upon individual performance and other factors, including whether an executive has caused Eastman to take excessive risk.

| • |  | Our stock ownership expectations are for the CEO to hold Eastman stock and stock-equivalents having a value of at least five times base annual pay and for the other executive officers to hold Eastman stock and stock-equivalents having a value of at least two-and-one-half times their respective base annual pay. We also prohibit our executive officers from entering into arrangements designed to hedge their exposure to changes in the market price of Eastman stock or from pledging Eastman stock as security or collateral for loans or in margin brokerage accounts. See “Information about Stock Ownership — Stock Ownership of Directors and Executive Officers — Director and Executive Stock Ownership Expectations; No Hedging or Pledging of Company Stock”. These policies ensure that each executive will have a significant amount of personal wealth tied to the long-term performance of Eastman stock and that their interests will remain aligned with those of our stockholders.

| • |  | The largest portion of total target executive pay is long-term, stock-based incentive compensation that vests, if earned, over a period of years. The stock payout opportunity combined with a multi-year vesting period encourages our executives to focus on maximizing Eastman’s long-term performance. These awards are made annually, so executives will continue to have unvested awards that will provide value only if our business continues to be appropriately managed and performing over the long term.

| • |  | A significant portion of executives’ long-term incentive compensation opportunities consist of performance share awards. Performance share award payouts are tied to how Eastman performs on certain metrics identified by the Compensation Committee as appropriately driving long-term stockholder value over a three-year period. This approach focuses management on sustaining the Company’s long-term performance. These awards also have overlapping performance periods, thereby discouraging excessive risk-taking in the near-term because such behavior could jeopardize the potential long-term payouts under other awards. To further ensure that there is not incentive for excessive risk-taking, the payout of these awards has been capped at 250% of target for each of the three-year performance periods.

| • |  | The variety of corporate and individual performance evaluated by the Compensation Committee to determine various forms of long-term and short-term incentive pay (including EBIT, EPS, cash flow, OCF, return on capital, employee safety, and TSR relative to peer companies) is designed to minimize the risk that executives will focus excessive attention on a single area of performance or performance measure.

2023 Proxy Statement 51

Executive Compensation — Compensation Discussion and Analysis

| • |  | Company policies and the plan under which our long-term stock-based incentive compensation awards are made require repayment of certain variable and incentive compensation amounts in the event of an accounting restatement due to material noncompliance by the Company with financial reporting requirements. See “Compensation Recoupment ‘Clawback’ Policy” below.

We believe that this combination of factors and features encourages our executives to manage our businesses and execute our strategy for growth in a prudent manner.

In 2022, Aon, the Compensation Committee’s independent compensation consultant, conducted a risk assessment of our compensation policies, programs, and practices, including executive compensation and broad-based compensation programs for all employees. Based on the results of Aon’s assessment, the Compensation Committee concluded that the Company’s compensation programs and practices are well aligned with corporate strategy, contain appropriate risk balancing and mitigation features, and are not structured in a way that should incent risk taking that is reasonably likely to have a material adverse effect on the Company.

Review of 2022 Executive Compensation

The Compensation Committee reviewed overall compensation of the Chief Executive Officer and the other executive officers and determined each component of executive compensation for 2022 as described below. As part of this review, the Compensation Committee:

| • |  | reviewed the design, terms, and value of each type of compensation and benefit for each executive officer, including annual incentive pay opportunities and long-term stock-based compensation awards, perquisites and personal benefits, deferred accounts, and retirement plans and determined that the amounts, individually and in the aggregate, were appropriate and in line with external market and internal comparisons;

| • |  | considered the estimated value of outstanding unvested, unexercised, and unrealized stock-based awards in its review of the types and values of each executive officer’s compensation; and

| • |  | determined the design, terms, amount, and forms of compensation considering:

| • |  | Company and individual performance;

Peer Group

The Compensation Committee believes that performance should be the primary basis on which compensation decisions are made. In December 2021, the Compensation Committee reviewed its compensation benchmarking peer group with assistance from Aon, and made no changes for 2022. The Compensation Committee used the following criteria in considering the compensation peer group (the “Peer Group”):

| • |  | size, including revenue, operating income, total assets, market capitalization, and enterprise value;

| • |  | global manufacturing focus;

| • |  | similar innovation-driven strategies;

| • |  | companies with which we compete for executive talent; and

| • |  | companies with a similar global workforce.

For 2022, the Compensation Committee compared total annual cash compensation opportunity (base salary and target incentive pay opportunity) design, terms, and levels and the design, terms, value, and mix of long-term stock-based incentive pay opportunity levels for the Company’s executive officers with previous year compensation of those of the following companies:

Air Products and Chemicals, Inc. |  | FMC Corporation
Ashland Global Holdings Inc. |  | The Goodyear Tire and Rubber Company
Ball Corporation |  | Mosaic Company
Celanese Corporation |  | Parker-Hannifin Corporation
Danaher Corporation |  | PPG Industries Inc.

Elements of our Executive Compensation

Primary Components of our Management Compensation Program and How Each Component Complements our Pay-for-Performance Philosophy and Objectives. Our management compensation program has three primary components — annual base salary, annual cash incentive compensation opportunity, and long-term stock-based incentive compensation opportunity. The Compensation Committee, with input from management and the Compensation Committee’s independent compensation consultant, designs, administers, and assesses the effectiveness of all executive compensation elements considering the market and our overall compensation philosophy and objectives. The Compensation Committee’s assessment includes review of the value of each element of pay and of total pay on a recognized and a realizable basis. The table below describes each principal element of executive pay, how the Compensation Committee determines the amount or size of such compensation, and the primary compensation objectives applicable to each type of pay.

Component |  | Form |  | Vesting or Performance Period |  | How Pay is Determined |  | Why We Pay Each Component
Annual Base Salary |  | Cash |  | Ongoing |  | Comparable pay for similar jobs at comparator companies Scope of responsibilities Work experience Comparable pay of other Eastman executives and for other Eastman jobs Individual performance |  | Recognize job responsibilities and contributions Attract and retain executive talent
Annual Incentive Compensation Opportunity |  | Cash |  | 1 year |  | Target awards are set as a percent of salary based on competitive data for similar jobs Payouts based on business and individual performance compared to pre-set expectations and targets |  | Motivate attainment of short-term business objectives and individual performance commitments consistent with long-term strategic plans
Long-Term Incentive Compensation Opportunity |  | Equity-Stock Options, Performance Shares, and Restricted Stock Units |  | 3 years (performance shares and restricted stock units performance period and options vesting period) and 10 years (options exercise period) |  | Target awards are a targeted dollar value based on competitive data; individual awards based on business and individual performance, contribution, and long-term potential Payouts and appreciation based on long-term capital returns and stock price appreciation |  | Motivate attainment of long-term corporate performance resulting in stock price appreciation Encourage ownership mindset by aligning interests with stockholders Attract and retain executive talent

Compensation Mix

The Compensation Committee believes that our mix of executive compensation components strikes an appropriate balance between the short- and long-term incentives for performance and risk taking. Eastman believes this mix aligns the interests of executive officers with those of other stockholders. For 2022, 93% of total target CEO compensation and 84% of total target compensation of the other named executive officers was at-risk and dependent on corporate and individual performance and relative total stockholder return.

CEO Pay Mix

Other NEOs Pay Mix

** | Grant date fair value of stock options granted in 2022. See Note 1 to the Summary Compensation Table below.

*** | Grant date accounting valuation of shares of Eastman common stock underlying performance shares awarded for the 2022-2024 performance period. See Note 1 to the Summary Compensation Table below.

How Base Salary and Annual Incentive Pay Levels Are Determined. For executive officers, targeted total cash compensation is intended to be competitive with comparable pay for similar jobs when target levels of corporate, business, and functional organization, and individual performance are achieved. The targeted levels of cash compensation take into account information provided by Aon and from publicly available information. For 2022, a significant portion of each executive officer’s total target compensation was variable, as shown above. Depending upon Company, business, and functional unit, and individual performance, executive officers could receive more or less than their target amount.

As requested by the Compensation Committee, Aon provided benchmarking analyses of the total cash compensation for executives with similar positions at the comparable companies. Aon also advised the Compensation Committee of general market cash compensation practices and trends. In determining each executive officer’s targeted total cash compensation, the Compensation Committee considered this benchmarking data and applied its judgment in considering the competitive market for executive talent, comparative pay levels of other executive officers, relative cash compensation of other jobs in the Company, and differences between the Company’s executive positions and those of the comparator companies, but did not benchmark specific compensation elements or total compensation to any specific percentile relative to the peer companies or the broader U.S. market. For 2022, the Compensation Committee set the targeted cash pay for executives taking into account not only competitive market data, but also factors such as Company, business, and individual performance, scope of responsibilities, critical needs and skill sets, leadership potential, and succession planning.

2023 Proxy Statement 55

Executive Compensation — Compensation Discussion and Analysis

Base Salary

In early 2022, after reviewing market competitive pay levels and the targeted total cash compensation of the executive officers, the Compensation Committee determined that base salary increases were appropriate for executive officers, increasing executive officer base salaries 3.48% to 6.45%. Mr. Costa’s base salary was not increased for 2022. In addition to external comparisons, the Compensation Committee considered the cash compensation levels of each executive officer relative to that of each other executive officer. The base salary amounts reported in the “Salary” column of the “Summary Compensation Table” were determined by the Compensation Committee based on the Compensation Committee’s target total cash compensation decisions for 2022.

Annual Incentive Pay

For executives, the annual incentive plan is known as the Unit Performance Plan (“UPP”). Under the UPP, the Compensation Committee sets a cash payout pool target amount at the beginning of each year, with the total available payout ranging from 0% to 200% of target amount depending on the Company’s financial performance. Although the payout pool calculated is based on actual corporate financial performance against the pre-set target measures, the Compensation Committee reserves discretion to adjust the total payout pool amount to reflect overall corporate performance, business and financial conditions, and other corporate objectives. The total UPP award pool is determined after the end of the performance year as the aggregate of the UPP payouts for each participant if the individual’s organizational and individual performance were at target levels, multiplied by a “performance factor” determined by calculated actual corporate performance compared to the pre-set performance goals, subject to adjustment for overall corporate performance and business and financial conditions.

HOW THE UPP WORKS
At the start of the year — Compensation Committee establishes corporate performance measures and targets and individual executive performance goals |  |  |  | Throughout the year — Compensation Committee tracks corporate and individual performance, considers adjustments to GAAP corporate performance measures |  |  |  | After year end — Compensation Committee determines corporate performance and any adjustments to calculated payout pool amount, Compensation Committee and management evaluate individual performance, and payout pool funded and individual awards distributed

2022 UPP Target Opportunities for Named Executive Officers. Consistent with our compensation objectives, as employees assume greater responsibilities, more of their pay is linked to corporate and individual performance. Variable UPP cash pay targets (expressed as a percentage of base salary) are established at the beginning of the performance year based on job responsibilities, relative targets for other Company positions, and comparable company practices. For the named executive officers, the target annual UPP incentive opportunities for 2022 were as follows:

Name |  | Title |  | Target UPP Opportunity as % of Base Salary
Mark J. Costa |  | Chief Executive Officer |  | 150%
William T. McLain, Jr. |  | Senior Vice President and Chief Financial Officer |  | 100%
Brad A. Lich |  | Executive Vice President and Chief Commercial Officer |  | 100%
Stephen G. Crawford |  | Executive Vice President, Manufacturing and Chief Sustainability Officer |  | 85%
Perry Stuckey III |  | Former Senior Vice President, Chief Human Resources Officer |  | 85%

Executive Compensation — Compensation Discussion and Analysis

2022 UPP Company Performance Measures and Targets. The Compensation Committee set the performance metrics, and related weightings and targets, for our 2022 executive compensation program in February 2022. The Compensation Committee believes that the performance targets it established were rigorous, while providing meaningful motivational value to our executives. The performance targets for 2022 emphasized the importance of our earnings performance and cash generation focusing on managing our manufacturing, selling, administrative, and general costs, and the importance of bringing in future new business. Our compensation programs were designed to allow Eastman to achieve these performance targets and ensure that we continue to be well positioned to meet the challenges ahead.

Following evaluation of the alignment of the Company’s incentive pay program and compensation philosophy with the Company’s business, products, and strategy for growth, the Committee determined that the 2022 UPP corporate performance and the corresponding payout pool should continue to be measured by adjusted EBIT (75%), the Company’s primary measure of operating performance, and by operating cash flow (25%).

| • |  | Adjusted EBIT under the 2022 UPP is GAAP earnings before interest and taxes as adjusted by the Compensation Committee for certain cost, charge, and income items that were not included in the Company’s targeted financial performance under management’s annual business plan as approved by the Board in early 2022 (the “annual business plan”) and that were excluded from EBIT in the non-GAAP financial measures disclosed by the Company in its public disclosures of financial results as non-core or unusual items in its Quarterly Reports on Form 10-Q and Annual Report on Form 10-K SEC filings. The selection of adjusted EBIT as a measure of 2022 corporate performance was intended to focus management level employees on both top-line revenues and bottom-line earnings and to allow measurement of UPP performance throughout the year based upon reported Company quarterly financial results.

| • |  | OCF under the 2022 UPP is GAAP cash provided by operating activities. OCF reflects the cash generated in the current year that enables the Company to invest in innovation in the core businesses and inorganic growth through acquisitions, and allows measurement of performance throughout the year based upon reported Company quarterly financial results.

In establishing the 2022 UPP adjusted EBIT and OCF performance targets in early 2022, the Compensation Committee considered the then-targeted 2022 financial and strategic performance under the annual business plan.

2022 UPP Company Performance Targets. For 2022, the adjusted EBIT target was $1.65 billion and the OCF target was $1.6 billion. The calculation of adjusted EBIT under the UPP for 2022 excluded from GAAP EBIT non-core items including asset impairments and restructuring charges, loss on divested businesses and related transaction costs, mark-to-market pension and other post-retirement benefit plans net loss, environmental and other costs, adjustments to contingent considerations and an unusual item costs, net of insurance proceeds, resulting from a January 31, 2022 operational incident at its Kingsport site as a result of a steam line failure (“steam line incident”). The 2022 UPP threshold, target, and maximum adjusted EBIT and OCF targets and corresponding payout multiples, actual adjusted EBIT and OCF, and resulting payout multiples for the portion of the UPP award pool applicable to executive officers are shown below.

2022 UPP Payouts. While adjusted non-GAAP EBIT was $1.34 billion for 2022, the expense associated with the minimum payout would have decreased adjusted non-GAAP EBIT below the threshold. The Company’s OCF for 2022 was $975 million, which also was below the threshold. After reviewing the Company’s overall corporate financial performance against these pre-established targets and certain non-financial operational excellence metrics, the Compensation Committee determined that no payout pool should be established under the UPP for executive officers and other management-level employees for 2022.

2023 Proxy Statement 57

Executive Compensation — Compensation Discussion and Analysis

UPP Payout Process. Each year, the Compensation Committee evaluates the Company’s performance against the UPP performance measures established in February each year. Based on this evaluation, the Compensation Committee considers approval of an overall payout pool for the UPP. The Compensation Committee then determines the portions of the overall UPP award pool, if any, to be allocated to the CEO and other NEOs as a group. In determining UPP payouts for the CEO and other NEOs, the Compensation Committee also considers the individual performance commitments for each executive.

The CEO, in consultation with the other executive officers, then determines the allocation of the overall UPP award pool, if any, to the various organizations within the Company for payouts to other management-level employees. The allocation is then typically based on their assessment of the performance of each organization relative to objectives established at the beginning of the performance year. Once each organization’s portion of the overall award pool is determined, management within each organization then allocates the organization’s portion of the Company award pool for individual payouts, based upon individual performance against the financial, organizational, and strategic performance objectives and expectations established at the beginning of the performance year.

Based on the Company’s performance against pre-established financial measures for 2022, the Compensation Committee did not approve a payout pool for the 2022 UPP. As such, there was no UPP allocation to the CEO or other NEOs. The chart below shows the percentages of target UPP payouts to executives for each of the last five years.

Executive Compensation — Compensation Discussion and Analysis

Although the Compensation Committee did not approve a payout pool for the 2022 UPP, it reviewed and evaluated the individual performance achievements for the CEO and other NEOs for 2022. This review helped inform the Compensation Committee’s decisions with respect to compensation targets for 2023 for the CEO and other current NEOs. Below is a summary of the achievements against the individual performance goals for 2022 for the continuing NEOs, some of which were adversely impacted by external factors that are described in the Company’s 2022 Form 10-K.

Named Executive Officer |  | Accomplishments / Commitments
Mark J. Costa |  | Given challenging market conditions, operating and supply chain constraints, broad-based inflation and significant currency headwinds, overall financial goals were not fully achieved in 2022.
|  | Under Mr. Costa’s leadership, Eastman: (i) made significant progress on its circular economy projects in 2022, which are expected to help position the Company for sustainable growth, and (ii) continued progress with its specialty innovation portfolio across the Company resulting in $550 million of new business revenue.
|  | Mr. Costa led Company initiatives that significantly increased year-over-year diversity hiring and strengthened the Company’s succession pipeline including acceleration of readiness for diverse talent for leadership roles.
William T. McLain, Jr. |  | Given market conditions and certain external events described in the Company’s Annual Report to Stockholders for 2022, goals related to earnings and cash flow (including OCF, variable cost margin, indirect cost savings, and operational budgets) were only partially achieved.
|  | In 2022, Mr. McLain played a key role in the successful completion of the divestiture of the Company’s adhesives resins business and continued to advance strategic growth opportunities through development of M&A portfolio opportunities.
|  | Mr. McLain led the development and implementation of initiatives to reduce selling, general and administrative expenses in 2022, and to reduce costs by $200 million in 2023.
Brad A. Lich |  | Revenues increased in the Advanced Materials and Fibers segments in 2022 (both segments under Mr. Lich’s leadership), but segment earnings were adversely impacted by significant decline in demand and destocking, as well as by operational, supply chain and inflation-related challenges during the year.
|  | Mr. Lich played an essential leadership role in progressing our three projects in the circular economy.
|  | Mr. Lich led a commercial team that continued to build and institutionalize its innovation capabilities through its integrated operating model.
Stephen G. Crawford |  | While the Company made significant strides in operational safety in 2022, unplanned operating outages and global logistics disruptions adversely impacted the Company’s business operations during the year.
|  | Under Mr. Crawford’s leadership, the Company made significant progress on advancing its circular platform initiatives including construction at Kingsport molecular recycling facility as well as development on two additional facilities.
|  | Mr. Crawford led sustainability initiatives that continued to make progress on the Company’s carbon emissions reduction commitment.

Executive Compensation — Compensation Discussion and Analysis

2023 Unit Performance Plan

In early 2023, the Compensation Committee evaluated the alignment of the current design of our UPP short-term incentive pay program. Following this evaluation, the Compensation Committee approved our annual cash incentive pay structure so that 2023 corporate performance and the corresponding payout pool will be measured by adjusted EBIT (75%) and by OCF (25%). The Committee also added a safety metric modifier that provides for possible upward or downward adjustments to the UPP payouts based on performance against prior year results. Although the payout pool calculated is based on actual corporate financial performance against the pre-set target measures, the Compensation Committee continues to reserve discretion to adjust the total payout pool amount to reflect overall corporate performance, business and financial conditions, and other corporate objectives.

Long-Term Incentive Compensation

Equity-based compensation is designed to facilitate stock ownership in order to link senior managers’ pay to the Company’s long-term performance to further align those managers’ interests with the interests of other stockholders. Important elements of the executive equity-based compensation program are:

Stock Options |  | Granted under the Company’s 2021 Omnibus Stock Compensation Plan (the “Omnibus Plan”), stock options create a direct link between compensation of key Company managers and long-term performance of the Company through appreciation of stock price.
Performance Shares |  | Awarded under the Omnibus Plan to provide an incentive for key managers to earn stock awards by meeting specified multi-year business or individual performance goals.
Other Stock-Based Incentive Pay |  | Under the Omnibus Plan, the Compensation Committee may also award additional stock-based compensation (with or without restrictions), including restricted stock units, performance units, stock appreciation rights, and additional stock options with performance-based or other conditions to vesting.
Stock Ownership Expectations |  | Established for executive officers to encourage long-term stock ownership and the holding of shares awarded under the Omnibus Plan or acquired upon exercise of options. Over a five-year period, executive officers are expected to accumulate stock with a value of two and one-half times their annual base salary (five times base salary for the Chief Executive Officer) in Company stock and stock equivalents. See “Information about Stock Ownership — Stock Ownership of Directors and Executive Officers — Director and Executive Stock Ownership Expectations; No Hedging or Pledging of Company Stock.” All executive officers have met or are on schedule to meet their ownership expectations.

Under the Company’s long-term incentive compensation program, executive officers receive stock option grants and performance share awards to directly link future compensation to stockholder and capital returns and as a retention incentive. The Compensation Committee has designed the current long-term incentive compensation program so that payouts are 100% at-risk. Since 2014, the program has been comprised of 75% performance shares and 25% stock options. While the long-term incentive compensation mix for the Peer Group for 2022 is not yet available, the publicly available information from 2021 indicates that the Peer Group average long-term incentive compensation mix for named executive officers includes approximately 17% time-vested RSUs, which are not at-risk nor performance based.

Executive Compensation — Compensation Discussion and Analysis

How Stock-Based Incentive Pay Levels Are Determined. The Compensation Committee establishes the annual value and mix of total stock-based incentive pay opportunities by considering recommendations from Aon based on long-term compensation survey data for the comparator companies listed under “Review of 2022 Executive Compensation.” As requested by the Compensation Committee, Aon provides benchmarking analysis of total target compensation and long-term stock-based compensation information, and also advises the Compensation Committee of general market stock-based incentive compensation practices and trends.

The Compensation Committee also regularly reviews with Aon the potential realizable value of each named executive officer’s outstanding unvested, unexercised, and unrealized stock-based awards compared to similar pay of executives at the comparable companies in determining stock-based incentive pay opportunity levels.

For 2022, stock options and performance shares were awarded at a target opportunity level intended to align total stock-based compensation with the mid-range of comparable stock-based compensation of the Peer Group. The grant date values of these awards that are reported in the “Summary Compensation Table” and “2022 Grants of Plan-Based Awards” table are accounting valuations that are calculated as of the effective grant date. Actual payouts for performance shares are determined by actual performance at the end of the three-year performance period.

Stock Options. In February 2022, the Compensation Committee approved stock options for each of the named executive officers comprising approximately 25% of the value of their respective long-term incentive compensation awards. The Compensation Committee grants time-vested stock options with an exercise price equal to the market price of the underlying stock on the grant date, and on the date of its authorization of grants it sets a grant date that is on or after the date of approval of the grant. In determining the size and terms of option awards, the Compensation Committee used the services of Aon to derive values of options using a variation of the Black-Scholes option-pricing model. In addition, Aon advises the Compensation Committee on the design of retention features of option grants. Computation of the value of option awards is comparable to values determined under FASB ASC Topic 718 and reported in the “2022 Grants of Plan-Based Awards” table below.

Long-Term Performance Shares. The other 75% of executive stock-based compensation awarded in February 2022 was in the form of performance shares. Shares of Company common stock are paid under performance shares based on the Company’s multi-year performance based on two measures:

• |  | a return on capital target established at the beginning of the three-year performance period; and

• |  | the Company’s TSR (change in stock price plus dividends declared during the performance period, assuming reinvestment of dividends) relative to a peer group of industrial companies as measured over a three-year period.

2023 Proxy Statement 61

Executive Compensation — Compensation Discussion and Analysis

The return on capital target is established considering corporate and strategic business plans and expectations for the performance period. Performance relative to the TSR target is determined by the Company’s quintile placement relative to the peer group of industrial companies at the end of the three-year performance period. If earned, awards are paid after the end of the performance period in unrestricted shares of Eastman common stock.

Consistent with recent and ongoing changes to the Company’s business, products, and strategy for growth, the Compensation Committee has designed performance shares awarded since 2015 with greater weight on relative TSR and less relative reward for higher levels of return on capital than for prior periods. The Compensation Committee has also updated the peer group of industrial companies to reflect the strategic emphasis on specialty businesses and products. The comparison companies for currently outstanding awards are the group of companies within the S&P 1500 “Materials Sector” that are classified by Standard & Poor’s as chemical companies, excluding The Chemours Company and Rayonier Advanced Materials and including Celanese Corporation, Westlake Chemical Corporation, and Huntsman Corporation. The S&P “Materials Sector” index is an index of industrial companies selected from the S&P “Super Composite 1500” Index.

Long-Term Compensation Targets

For the 2023-2025 performance period, the Compensation Committee approved a target for return on capital of 9.26%, which was driven by the same factors that impacted the Company’s EBIT, as described above. Performance relative TSR is determined by the Company’s quintile placement relative to the “Chemical Companies of the S&P 1500” at the end of the three-year performance period.

The Compensation Committee added a modifier element to the performance share awards for 2023-2025 to include parameters around I&D and ESG aligning executive compensation incentives with I&D and ESG goals (the “Modifier”). As the Company’s ESG and human capital management strategy and goal setting evolve and mature, the Compensation Committee expects to correspondingly evolve and mature these aspects of the executive compensation program.

The Modifier impacts the performance outcomes for the Company’s performance shares based on improvements in the I&D of employees and in reduction of GHG over the 2023 – 2025 performance period, and is assessed by the following 4 measures:

ESG Goals |  | Target
Climate Change — Decrease Actual GHG Emissions |  | Reduce by 17.1% to 25.2% or better from 2017 baseline target
Circularity — Millions of Pounds of Waste Plastic Recycled |  | 215 — 250 million pounds or better in the aggregate by 2025
I&D Goals |  |
U.S. Diversity Representation Total Professional (Business and Technical & Leadership) Population Goals (2024 # on track for 2030 Goals) |  | 21% — 25% or better (People of Color)
Gender Representation Total Professional (Business and Technical & Leadership) Population Goals (2024 # on track for 2030 Goals) |  | 41% — 42% or better (Female)
The Compensation Committee will use its judgement in determining the Modifier to be applied to the 2023-2025 Performance Share Award, using the following guidelines: •  Target or better performance in all 4 measures = +10% •  Target or better performance in 3 of the 4 measures = +7.5% •  Target or better performance in 2 of the 4 measures = +5% •  Target or better performance in 1 of the 4 measures = +2.5% •  If all measures are below targeted performance, then the award will be reduced by (-5.0%).

Return on capital performance is determined based on the arithmetic average for each of the years during the performance period of our average return on capital.

| • |  | “Return on capital” is our earnings from continuing operations, adjusted to exclude the same non-core or unusual items as are excluded from earnings in the Company’s non-GAAP financial measures, divided by the average capital employed, each as defined in the form of the 2022-2024 performance share award filed as Exhibit 10.18 to the Company’s Annual Report on Form 10-K for the year ended December 31, 2021, filed with the SEC. The resulting ratio is multiplied by 100 in order to convert it to a percentage.

| • |  | TSR performance is determined based on our TSR during the performance period relative to the TSRs of the companies in the comparable group during the performance period. Performance share TSR means total stockholder return as reflected by the sum of (i) change in stock price (measured as the difference between (a) the average of the closing prices of a company’s common stock in the period beginning on the tenth trading day preceding the beginning of the performance period and ending on the tenth trading day of the performance period and (b) the average of such closing prices for such stock in the period beginning on the tenth trading day preceding the end of the performance period and ending on the tenth trading day following the end of the performance period) plus (ii) dividends declared, assuming reinvestment of dividends, and expressed as a percentage return on a stockholder’s hypothetical investment.

Although the actual payout of the performance share awards in 2022 will not be determinable until after the end of the performance period in 2024, a grant date fair value of such awards (which is an accounting valuation that is calculated as of the award date) is reported in the 2022 “Stock Awards” column of the Summary Compensation Table and the range of possible share payouts is reported in the “Estimated Future Payouts Under Equity Incentive Plan Awards” column of the “2022 Grants of Plan-Based Awards” table. These awards have challenging long-term targets for returns on capital and to investors. Actual possible payouts are aligned with our pay-for-performance philosophy. The accounting methodology for the valuation of performance shares in the compensation tables uses predictive financial models of company performance, and results in a valuation that may be substantially different than the actual payouts.

For the 2020 — 2022 performance share awards, the Committee approved payouts for the named executive officers at 100% of target award levels (of a possible 250% of the target award) based on the Company’s three year (2020-2022) total stockholder ranking in the 3rd quintile (40-49%) of compared companies and the Company attaining an average return of 10.30% (compared to a target return goal of 8.51%). Measurement of return on capital under the performance shares was based on non-GAAP earnings excluding the same items as excluded in the non-GAAP financial measures disclosed by the Company for 2020, 2021 and 2022 (loss on divested businesses and related transaction costs, mark-to-market pension and other post-retirement benefit plans net (gain)/loss, asset impairments and restructuring charges and related accelerated depreciation costs, early debt extinguishment costs, environmental and other costs, adjustments to contingent considerations, steam line incident costs, net of insurance proceeds, and adjustments from tax law changes). These adjustments increased the calculated earnings from continuing operations by $361 million in 2020, $356 million in 2021 and $191 million in 2022 for the calculated payout multiple from 60% to 100%, aligning the payout with performance compared to the long-term forecast measure on which the target performance was based.

The Compensation Committee’s exclusion of non-core and unusual items from its measure of return on capital for purposes of determining three-year performance share payouts is intended to motivate and reward accomplishment of strategic decisions and actions in execution of the strategy for long-term growth.

The performance share values in the pay tables reflect the robust performance expectations underlying the targeted performance. Over the last three performance cycles the actual performance share payouts have been:

Executive Compensation — Compensation Discussion and Analysis

Other Compensation and Benefits. The Company’s executive officers also participate in benefits plans generally available to all other employees, including nonqualified supplemental retirement plans for U.S. employees with pay above Internal Revenue Code limits, and in a deferred compensation plan for management-level employees. These benefits are intended to keep us competitive in attracting and retaining executive and other management-level employees. See “Pension Benefits” and “2022 Nonqualified Deferred Compensation” in the “Compensation Tables” section below. We have also entered into limited change in control severance agreements with certain of our executive officers and provide a modest program of executive perquisites and personal benefits which serve the specific purposes described in this Compensation Discussion and Analysis and under “Compensation Tables — Summary Compensation Table” and “Termination and Change-in-Control Arrangements” below.

Executive Perquisites and Personal Benefits

The Company provides only limited perquisites to our named executive officers, and those perquisites are designed to provide specific benefits. The Compensation Committee annually reviews the types and amounts of perquisites provided to executive officers and tax treatment of those perquisites for both the Company and the executive officers. Perquisites provided to executive officers for 2022 were:

| • |  | personal umbrella liability insurance coverage;

| • |  | home security system;

| • |  | non-business travel on corporate aircraft by executives, their families, and invited guests when seats are available and the aircraft is otherwise being used for Company business, including added destination of a flight when the plane is otherwise in reasonable proximity to the added destination;

| • |  | financial planning services; and

| • |  | supplemental long-term disability insurance for a portion of executives’ annual cash compensation not replaced in the event of their disability under the all-employee long-term disability insurance plan.

In addition, the Compensation Committee has determined that it is appropriate that the Chief Executive Officer use corporate aircraft whenever possible for both business and personal travel (and for his family when they are traveling with him). This is: (i) to allow travel time to be used productively for the Company, (ii) for security, health, and safety reasons (consistent with recommendations of a periodic, third-party Personal Vulnerability Security Assessment), and (iii) to be sure that Mr. Costa can be immediately available to respond to business priorities from any location around the world. This personal use is accounted for and periodically reviewed by the Compensation Committee. In connection therewith, the Nominating and Corporate Governance Committee authorized the Company to enter into an aircraft time sharing agreement (the “Agreement”) with Mr. Costa in January 2023. Under the Agreement, Mr. Costa is permitted to utilize Company aircraft from time to time on an “as needed and as available” basis. For any personal flights operated under this Agreement, Mr. Costa will reimburse the Company for the aggregate incremental cost of his personal use of Company aircraft under the Agreement. All personal flights not reimbursed under the Agreement will be included in the “Summary Compensation Table” as a perquisite. See “Summary Compensation Table-All Other Compensation” for a summary of the aggregate incremental costs to the Company of Mr. Costa’s personal aircraft use in 2022.

There are no tax gross-up payments made by the Company for any imputed income to the executive officers on perquisites or personal benefits.

Executive Compensation — Compensation Discussion and Analysis

Executive Termination and Change-in-Control Agreements

The Company recognizes that the occurrence, or potential occurrence, of a change-in-control transaction can create uncertainty regarding the continued employment of our executive officers. This uncertainty results from the fact that many change-in-control transactions result in significant organizational changes, particularly at the senior executive level. Accordingly, the Company believes that severance protections in the context of a change-in-control transaction can play a valuable role in attracting and retaining key executive officers. In order to encourage our executive officers to remain focused on maximizing stockholder value when their prospects for continued employment following a transaction are often uncertain, we provide certain of our executive officers with severance benefits if their employment is terminated by the Company without “cause” or by the executive for “good reason” in connection with a change-in-control. Detailed information regarding these change-in-control severance agreements and the benefits they provide is included in the “Termination and Change-in-Control Arrangements” section of this proxy statement.

The Compensation Committee evaluates the level of severance benefits payable to each executive officer, and considers these severance protections an important part of executives’ compensation and consistent with practices of peer companies. Consistent with recommendations from Aon and current market and peer company practices, the Compensation Committee has approved and the Company has entered into change-in-control severance agreements with the named executive officers and certain other executive officers that provide for payments of no more than three-times base salary plus target annual variable cash pay opportunity for the Chief Executive Officer and two-times base salary plus target annual variable cash pay opportunity for other executive officers and which do not provide for any tax “gross up” payments to executives.

Compensation Recoupment “Clawback” Policy

The Sarbanes-Oxley Act of 2002, Company policy, and pending provisions of the Dodd-Frank Act govern the process for reimbursement by executive officers of certain cash bonus or other incentive-based or equity-based compensation (sometimes referred to as “clawback”) received following public disclosure of an accounting restatement due to material noncompliance by the Company with any financial reporting requirements. In addition, certain outstanding awards under our Omnibus Long-Term Compensation Plans require reimbursement of certain amounts from awards following an accounting restatement due to material noncompliance by the Company with any financial reporting requirement.

The Compensation Committee has adopted an additional executive clawback policy which requires that, if the Company is required to prepare an accounting restatement due to material noncompliance with financial reporting requirements, then any current and former executive officers who willfully committed an act of fraud, dishonesty, or recklessness that contributed to the noncompliance would be required to repay the amount of incentive-based compensation paid or granted to that executive within three years before the accounting restatement that was in excess of the amount that would have been paid or granted to that executive if the restated financial statements had originally been prepared and disclosed. The clawback policy was adopted in advance of final rules or regulations (“Final Regulations”) adopted by the SEC and listing requirements to be adopted by the New York Stock Exchange that would implement the incentive-based compensation recovery requirements of the Dodd-Frank Act. The clawback policy will remain operative until it is amended to conform to the requirements that are contained in the Final Regulations and, if necessary, the clawback policy will be interpreted and administered consistent with such Final Regulations.

(1) Grant date fair value of awards of performance shares (reported in the “Stock Awards” column) and options (reported in the “Option Awards” column) made in the year indicated, computed in accordance with FASB ASC Topic 718. The grant date fair values of performance share awards uses predictive financial models of Company relative stock price and financial performance, including assumptions of potential of achievement of relative TSR and return on capital targets underlying the awards, calculated in accordance with FASB ASC Topic 718 based on a multi-factor Monte Carlo simulation. See note 18 to the Company’s consolidated financial statements in the Annual Report to Stockholders for 2022 mailed and delivered electronically with this proxy statement for a description of the assumptions made in the valuation of 2022 stock awards under FASB ASC Topic 718.

Performance share awards were made for performance periods beginning January 1, 2020 and ending December 31, 2022, beginning January 1, 2021 and ending December 31, 2023, and beginning January 1, 2022

2023 Proxy Statement 67

Executive Compensation — Compensation Tables

and ending December 31, 2024, respectively. The potential maximum grant date value of the performance share awards assuming the highest level of performance, computed in accordance with FASB ASC Topic 718, were: Mr. Costa (2020 — $10,790,335, 2021 — $12,727,966, 2022 — $13,879,095); Mr. McLain (2020 — $1,686,091, 2021 — $2,672,196, 2022 — $3,290,919); Mr. Lich (2020 — $2,697,584, 2021 — $3,234,856, 2022 — $3,290,919); Mr. Crawford (2020 — $1,629,885, 2021 — $2,390,964, 2022 — $2,861,794); and Mr. Stuckey (2022 — $2,289,305).

(3) | Cash payments made in the following year for performance in the year indicated under the UPP. As described in the “Compensation Discussion and Analysis” preceding these tables and in the “2022 Grants of Plan-Based Awards” table below, the UPP is the Company’s annual incentive pay program under which a portion of the total annual compensation of executive officers and other management-level employees is dependent upon corporate, organizational, and individual performance.

(4) | “Change in Pension Value” is the aggregate change in actuarial present value of the named executive officer’s accumulated benefit under all defined benefit and actuarial retirement plans, which are the Company’s tax-qualified defined benefit pension plan (the Eastman Retirement Assistance Plan, or “ERAP”) and unfunded, nonqualified retirement plans supplemental to the ERAP that provide benefits in excess of those allowed under the ERAP (the Eastman Unfunded Retirement Income Plan, or “URIP”, and the Eastman Excess Retirement Income Plan, or “ERIP”). These changes in present value are not directly related to final payout potential, and can vary significantly year-over-year based on (i) promotions and corresponding changes in salary; (ii) other one-time adjustments to salary or other reasons; (iii) actual age versus predicted age at retirement; (iv) the interest (or “discount”) rate used to determine present value of benefit; and (v) other relevant factors. A decrease in the discount rate results in an increase in the present value of the accumulated benefit without any increase in the benefits payable to the named executive officer at retirement and an increase in the discount rate has the opposite effect.

The aggregate increase in actuarial value of the pension plans is computed as of the same pension plan measurement date used for financial statement reporting purposes with respect to the Company’s financial statements for 2022, 2021, and 2020. The actuarial present value calculations are based on prescribed Internal Revenue Service (“IRS”) mortality tables and assume individual compensation and service through December 31, 2022, December 31, 2021, and December 31, 2020, respectively, with benefit commencement at the normal retirement age of 65. Benefits are discounted using a 5.58% discount rate for both the ERAP and the ERIP/URIP for the 2022 calculation, using a 2.91% discount rate for the ERAP and a 2.87% discount rate for the ERIP/URIP for the 2021 calculation, and using a 2.52% discount rate for the ERAP and a 2.45% discount rate for the ERIP/URIP for the 2020 calculation. See the “Pension Benefits” table for additional information about the named executive officers’ participation in and benefits under the pension plans.

“Nonqualified Deferred Compensation Earnings” refers to above-market or preferential earnings on compensation that is deferred on a basis that is not tax-qualified, including such earnings on amounts in nonqualified defined contribution plans. The Company maintains the Executive Deferred Compensation Plan (the “EDCP”), an unfunded, nonqualified deferred compensation plan into which executive officers can defer compensation until retirement or termination from the Company. For 2022, 2021, and 2020 there were no preferential or above-market earnings on amounts in individual EDCP accounts (defined as appreciation in value and dividend equivalents earned at a rate higher than appreciation in value and dividends on common stock and interest on amounts deferred at a rate exceeding 120% of the federal long term rate). See the “2022 Nonqualified Deferred Compensation” table for additional information about the named executive officers’ EDCP accounts.

(5) | The items of “All Other Compensation” reported for the named executive officers for 2022 are identified and quantified below:

| • |  | Annual Company contributions to defined contribution plans. The amounts reported for 2022 are the total annual Company contributions to the accounts of Messrs. Costa ($239,163), McLain ($102,157), Lich ($103,396), Crawford ($82,527), and Stuckey ($71,748) in the Eastman Investment Plan, a 401(k) retirement plan, and in the EDCP. Contributions to the Eastman Investment Plan equaled $15,250 for each named executive officer, with the remaining

| Company contributions to their respective EDCP accounts. See the “2022 Nonqualified Deferred Compensation” table for additional information about Company contributions into the named executive officers’ EDCP accounts. Annual Company contributions were based upon actual compensation paid during the calendar year.

| • |  | Amounts included for Perry Stuckey III. In addition to the perquisites listed in the table below, Mr. Stuckey’s involuntary separation agreement provides for: (i) payments equal to one year’s base salary ($600,000); (ii) an amount equivalent to his annual target bonus ($510,000); and (iii) direct payment or reimbursement of up to 12 months of COBRA premiums.

| • |  | Perquisites and other personal benefits. The amounts reported for 2022 are the aggregate values, based on the incremental cost to the Company, of perquisites and personal benefits to the named executive officers (described in “Compensation Discussion and Analysis — Executive Perquisites and Personal Benefits”) as quantified in the following table:

The aggregate incremental cost to the Company for operating the corporate aircraft for non-business flights, including non-business added destination portions of business flights, is based upon calculation of direct operating costs including fuel, fuel additives, lubricants, maintenance, reserves for engine restoration and overhaul, landing and parking expenses, crew expenses, and miscellaneous supplies and catering (including for any “deadhead” segments of such flights when the aircraft flies empty before picking up or dropping off the executive). In 2022, inflation impacted the variable hourly operating costs of corporate aircraft, including fuel, maintenance cost, airport fees, parking, and crew travel costs. Fuel costs per hour increased more than 30% from 2021. The aggregate incremental cost to the Company for flying additional passengers on business flights is a de minimis amount, and no amount is included for any such flights for purposes of determining “All Other Compensation”. The aggregate incremental costs to the Company of the umbrella liability insurance, the home security system, financial counseling and supplemental long-term disability insurance are the actual amounts paid by the Company.

(1) | The Compensation Committee made stock option grants and performance share awards for the 2022-2024 performance period in February 2022.

(2) | Performance share awards for 2022-2024 were effective as of the beginning of the performance period on January 1, 2022. The UPP award opportunities relate to 2022 performance.

(3) | Estimated possible payouts for 2022 under the UPP. The “Threshold” column reflects the 50% payout level if performance is at minimum of 80% of target levels. The “Target” column reflects the 100% payout level if performance is at 100% of target levels. The “Maximum” column reflects the 200% payout level if performance is at or above 115% of target levels for specified above-goal performance. Based on the Company’s performance against pre-established financial measures for 2022, the Compensation Committee did not approve a payout pool for the 2022 UPP. See “Compensation Discussion and Analysis” for a description of the UPP.

(4) | Estimated future share payouts at threshold, target, and maximum levels for performance shares for the 2022-2024 performance period, assuming performance conditions are satisfied. See also “Compensation Discussion and Analysis” for a description of how performance share payouts are determined, “Outstanding Equity Awards at 2022 Year-End” table, and “Termination and Change-in-Control Arrangements”.

(5) | Nonqualified stock options granted during 2022. Options granted in 2022 have an exercise price equal to the closing price on the New York Stock Exchange of the underlying common stock on the date of grant. The stock options vest and become exercisable in one-third increments on each of the first three anniversaries of the grant date, with acceleration of vesting if, following a “change in control”, (i) the grantee’s employment is terminated other than due to death, disability, cause, resignation, or retirement or (ii) the award cannot be continued or replaced with an award

| for another public company stock because Eastman common stock (or the stock of the successor company) ceases to be publicly traded in a national securities market. For more information about these “change in control” provisions, see “Omnibus Stock Compensation Plans” under “Termination and Change-in-Control Arrangements”. Stock options generally expire ten years from the date of grant. Upon termination by reason of death, disability, or retirement, the stock options remain exercisable for the lesser of five years following the date of termination or the expiration date. If an employee resigns, the stock options remain exercisable for the lesser of 90 days or the expiration date. Stock options not previously exercised are canceled and forfeited upon termination for cause. See “Summary Compensation Table”, “Outstanding Equity Awards at 2022 Year-End” and “2022 Option Exercises and Stock Vested” tables, and “Termination and Change-in-Control Arrangements”.

(6) | Per-share exercise prices of the stock options granted in 2022. The exercise price is the closing price of common stock on the New York Stock Exchange on the grant date.

(1) | The ERAP is a tax-qualified, non-contributory defined benefit pension plan that generally covers employees who became employed on or before December 31, 2006. A participant’s total ERAP benefit consists of his or her “Pre-2000 Benefit” and “Pension Equity Benefit,” as described below:

Pre-2000 Benefit. Prior to 2000, the ERAP used a traditional pension formula which gave each participant a life annuity commencing at age 65. A participant is eligible for an unreduced Pre-2000 Benefit when such participant’s aggregate age plus years of eligible service totals 85, or at age 65. At retirement, the actuarial present value of the future annual Pre-2000 Benefit payments may at the election of the participant be paid in a lump sum. Benefits

74 2023 Proxy Statement

Executive Compensation — Compensation Tables

earned during 1998 and 1999, upon the election of the participant, may be payable over five years. The Pre-2000 Benefits payable upon retirement are based upon the participant’s years of service with the Company and “average participating compensation,” which is the average of three years of those earnings described in the ERAP as “participating compensation.” “Participating compensation,” in the case of the named executive officers consists of salary, bonus, and non-equity incentive plan compensation, including an allowance in lieu of salary for authorized periods of absence, such as illness, vacation, and holidays. To the extent that any participant’s annual Pre-2000 Benefit exceeds the amount payable under the ERAP, such excess will be paid from one or more unfunded, supplementary plans.

Pension Equity Benefit. Effective January 1, 2000, the Company redesigned the ERAP to use a pension equity formula. Under the pension equity formula, beginning January 1, 2000, a participant earns a certain percentage of final average earnings each year based upon age and total service with the Company. When a participant terminates employment, he or she is entitled to a pension amount, payable over five years. The amount may also be converted to various forms of annuities. To the extent that any participant’s Pension Equity Benefit exceeds the amount payable under the ERAP, such excess will be paid from one or more unfunded, supplementary plans.

(2) | The Company maintains two unfunded, nonqualified plans, the URIP and the ERIP. The ERIP and the URIP will restore to participants in the ERAP benefits that cannot be paid under the ERAP because of applicable tax law limits, and benefits that are not accrued under the ERAP because of a voluntary deferral by the participant of compensation that would otherwise be counted for benefit calculation under the ERAP. The Company has established a “Rabbi Trust” to provide a degree of financial security for the participants’ unfunded account balances under the ERIP and URIP. See “Termination and Change-in-Control Arrangements — Benefit Security Trust.”

(3) | Actuarial present value of the accumulated benefit, computed as of the same pension plan measurement date used for financial statement reporting purposes with respect to the Company’s audited financial statements for 2022. The actuarial present value calculation is based on the prescribed IRS mortality tables, and assumes individual compensation and service through December 31, 2022, with benefit commencement at normal retirement age of 65. Benefits are discounted to present value using a 5.58% discount rate for both the ERAP and the ERIP/URIP.

(4) | Mr. Stuckey joined the Company on May 31, 2011. The ERAP and ERIP/URIP were closed to new participants on January 1, 2007. Therefore Mr. Stuckey is not eligible for benefits under these plans.

The following table is a summary of participation by the individuals named in the Summary Compensation Table in the EDCP, an unfunded, nonqualified deferred compensation plan into which executive officers and other management-level employees can defer compensation until retirement or termination from the Company. Annual base and incentive cash compensation, stock and stock-based awards which are payable in cash and allowed to be deferred, and special compensation payable in connection with the employee’s initial employment with the Company may be deferred into the EDCP. Compensation deferred into the EDCP is credited at the election of the employee to multiple hypothetical investment alternatives, including an Eastman stock fund. Amounts deferred into the Eastman stock account increase or decrease in value depending on the market price of Eastman common stock. When cash dividends are declared on Eastman common stock, each stock account receives a dividend equivalent which is used to hypothetically “purchase” additional shares. Upon retirement or termination of employment, the value of a participant’s EDCP account is paid, in cash, in a single lump sum or in up to ten annual installments as elected in advance by the participant. The EDCP also provides for early withdrawal by a participant of amounts in his or her EDCP account in certain limited circumstances.

All amounts in the following table have been previously earned by the named executive officers and reported by the Company as compensation in this proxy statement or in annual meeting proxy statements for previous years, and are not new or additional compensation to the named executive officers.

Executive Compensation — Termination and Change-in-Control Arrangements

Termination and Change-in-Control Arrangements

The Company’s Change-in-Control Agreements with certain executive officers, including the individuals named in the Summary Compensation Table, and the Omnibus Long-Term Compensation Plans, provide for compensation and benefits in certain circumstances upon or following termination of the executive or a change-in-control of the Company. Circumstances that trigger compensation or provision of benefits related to termination or change in control, how such compensation and benefits are determined, and conditions or obligations applicable to the receipt of payments and benefits are described below.

Change-in-Control Agreements. For the reasons described in the “Compensation Discussion and Analysis”, the Company has entered into Change-in-Control Agreements (the “Agreements”) with the individuals named in the Summary Compensation Table and certain other executive officers of the Company. The Agreements provide for specified compensation and benefits following a “change-in-control” of the Company. A “change-in-control” is generally defined in the Agreements to include the following, subject to certain exceptions: (i) the acquisition by a person of 35% or more of the voting stock of the Company; (ii) the incumbent Board members (and subsequent directors approved by them) ceasing to constitute a majority of the Board; (iii) approval by the Company’s stockholders of a reorganization or merger unless, after such proposed transaction, the former stockholders of the Company will own more than 50% of the resulting corporation’s voting stock, no person will own 35% or more of the resulting corporation’s voting stock, and the incumbent Board members will continue to constitute at least a majority of the Board of the resulting corporation; or (iv) approval by the Company’s stockholders of a complete liquidation or dissolution of the Company.

Under the Agreements, in the event that a change-in-control of the Company occurs during the “change-in-control period,” the Company agrees to continue to employ the executive for a period of two years after the occurrence of such change-in-control (the “Employment Period”). The “change-in-control period” means the period commencing on December 1, 2022, and ending two years after such date; provided that on each anniversary of the Agreements, the “change-in-control” period is automatically extended so as to terminate two years after such anniversary, unless the Company provides timely notice to the executive that it will not extend the period.

During the Employment Period, the executive would be entitled to: (i) an annual base salary at a rate at least equal to the base salary in effect on the date of the change-in-control; (ii) an annual bonus at least equal to the executive’s target bonus opportunity for the last full fiscal year prior to the change-in-control; and (iii) continued participation in all incentive, savings, retirement, welfare benefit, and fringe benefit plans applicable to other peer executives of the Company on terms no less favorable than those in effect during the 120-day period preceding the change in control.

The Agreements also specify the payments and benefits to which an executive would be entitled upon a termination of employment during the Employment Period for specified reasons, including death, retirement, disability, termination by the Company with or without cause, and termination by the executive for or without good reason (as such terms are defined in the Agreements).

If an executive’s employment were to be terminated by the Company for any reason other than for cause or disability, or by the executive for good reason, during the Employment Period, the Company would be required to:

| (i) | pay to the executive a lump sum cash payment equal to his or her “accrued obligations” (unpaid base salary through the date of termination, a prorated target bonus for the year of termination, and any accrued vacation pay);

| (ii) | pay to the executive a lump sum severance payment equal to three-times (in the case of the Chief Executive Officer) or two-times (in the case of the other executives) the sum of his or her then-current annual base salary plus the amount of his or her target annual bonus for the year in which the termination occurs;

| (iii) | continue to provide all health and welfare benefits to the executive and his or her eligible dependents, subject to certain limitations, for 18 months following termination;

2023 Proxy Statement 77

Executive Compensation — Termination and Change-in-Control Arrangements

| (iv) | accelerate the vesting of the executive’s unvested benefits under the Company’s retirement plans, and pay to the executive a lump sum cash payment equal to the value of such unvested benefits; and

| (v) | pay or provide to the executive any other amounts or benefits to which he or she was entitled under any of the Company’s plans, programs, policies, practices, contracts, or agreements then in effect.

Upon the termination of an executive’s employment by reason of death, disability, or retirement, or upon a termination by the Company for cause or by the executive without good reason, the Agreements would terminate without further obligation of the Company other than the payment of base salary through the date of termination and any other amounts or benefits to which the executive was entitled under any of the Company’s plans, programs, policies, practices, contracts, or agreements then in effect.

“Cause” is defined in the Agreements as a material breach by the executive of any provision of his or her agreement; the conviction of the executive of any criminal act that the Board deems to constitute cause; a material breach by the executive of a published Company code of conduct or code of ethics; or conduct by the executive in his or her office with the Company that is grossly inappropriate and demonstrably likely to lead to material injury to the Company, as determined by the Board.

“Good reason” is defined in the Agreements as the assignment to the executive of any duties that are materially inconsistent with his or her position (including status, offices, titles, and reporting requirements), authority, duties, or responsibilities, or any other action by the Company which results in a material diminution in such position, authority, duties, or responsibilities (excluding an isolated, insubstantial, and inadvertent action not taken in bad faith and which is remedied by the Company promptly after notice from the executive); a reduction by the Company in executive’s base salary or target annual bonus; any failure by the Company to comply with any provisions of his or her agreement (other than an isolated, insubstantial, and inadvertent failure not occurring in bad faith and which is remedied by the Company promptly after notice from the executive); the Company’s requiring the executive to be based at any office or location 50 miles or more from his or her current location; any failure by the Company to have a successor to the Company agree to assume the agreement; or a material breach by the Company of any other provision of the executive’s agreement.

The Agreements contain certain other typical provisions for agreements of this type, including a requirement that the executive not disclose any confidential information of the Company following termination of employment, and providing that the Company will reimburse the executive on a then-current basis for reasonable fees and expenses in seeking to enforce the Agreement (subject to repayment if his or her claims are determined to be frivolous or in bad faith).

Omnibus Stock Compensation Plans. The Company’s 2021 Omnibus Stock Compensation Plan (like its predecessor plans, collectively referred to as the “Omnibus Plans”) provides for grants to employees of nonqualified and incentive stock options, stock appreciation rights, stock awards, performance shares, and other stock and stock-based awards (collectively, “awards”).

The Omnibus Plans contain provisions regarding the treatment of awards in the event of a “change-in-control” (as defined, generally involving circumstances in which the Company is acquired by another entity or its controlling ownership is changed). Upon a change-in-control, the rules described below will generally apply to awards granted under the Omnibus Plans.

However, the Compensation Committee has the discretion, notwithstanding any particular transaction constituting a change-in-control, either to determine that such transaction is of the type that does not warrant the described consequences with respect to awards (in which case such consequences would not occur) or to alter the way in which awards are treated from the consequences outlined in the Omnibus Plans.

78 2023 Proxy Statement

Executive Compensation — Termination and Change-in-Control Arrangements

In the event of a change-in-control (assuming the Compensation Committee has not exercised its discretion described above), if (i) a participant’s employment terminates within two years following the change-in-control, unless such termination is due to death, disability, cause, resignation (other than as a result of certain actions by the Company and any successor), or retirement or (ii) Eastman common stock (or the stock of any successor company received in exchange for Eastman common stock) is no longer publicly traded on a national securities market, participants will be entitled to the following treatment. All conditions, restrictions, and limitations in effect with respect to any unvested, unexercised, unpaid, or deferred awards will immediately lapse and no other terms or conditions will be applied. Any unexercised, unvested, unearned, or unpaid awards will automatically become 100% vested. For performance shares, the performance period will immediately terminate and, unless the Compensation Committee has already determined actual performance for the applicable performance period, the awards will be earned (pro rata for the number of completed performance periods months) based on (i) the target level of performance if the change in control occurs during the first half of the performance period or (ii) based on actual performance through the end of the last quarter prior to the change in control if the change in control occurs during the second half of the performance period.

In order to comply with Section 409A of the Internal Revenue Code, it may be necessary for the Company to delay payments until six months following the officer’s separation from service with the Company.

Potential Payments Under Termination and Change-in-Control Arrangements. The following table shows, for each of the named executive officers employed at December 31, 2022, the payments and benefits that generally would have been provided under the Change-in-Control Agreements and the Omnibus Plans if the executive had been terminated without “cause” or had resigned for “good reason” on December 31, 2022, following a change-in-control (or, in the case of awards under the Omnibus Plans, Eastman common stock or the stock of its successor is no longer publicly traded on a national securities exchange following the change-in-control).

In addition to the payments described above, the named executive officers would also receive the following payments for amounts already earned or vested as the result of participation in compensation or benefit plans on the same basis as other Company employees:

| • |  | value of outstanding vested stock-based awards (see the “Outstanding Equity Awards at 2022 Year-End” table),

| • |  | earned UPP payout (see “Estimated Future Payouts Under Non-Equity Incentive Plan Awards” column in the “2022 Grants of Plan-Based Awards” table),

| • |  | lump sum present value of pension under the Company’s qualified and non-qualified pension arrangements (see “Present Value of Accumulated Benefit” column in the “Pension Benefits” table).

Benefit Security Trust. The Company has established a Benefit Security Trust (sometimes referred to as the “Rabbi Trust”) to provide a degree of financial security for its unfunded obligations under the EDCP, the supplemental ERAP plans, and the Agreements with the Company’s executives. The assets of the Rabbi Trust would be subject to the claims of the Company’s creditors in the event of insolvency. Upon the occurrence of a “change-in-control” or a “potential change-in-control” (each as defined below), or if the Company fails to meet its payment obligations under the covered plans and Agreements, the Company would be required to transfer to the trustee cash or other liquid funds in an amount equal to the value of the Company’s obligations under the covered plans and Agreements. The Company has conveyed to the trustee rights to certain assets as partial security for the Company’s funding obligations under the Rabbi Trust.

A “change-in-control” for purposes of the Rabbi Trust is generally defined to include the following, subject to certain exceptions: (i) the acquisition by a person (other than the Company, certain affiliated entities, or certain institutional investors) of 19% or more of the voting stock of the Company; (ii) the incumbent Board members (and subsequent directors approved by them) ceasing to constitute a majority of the Board; (iii) approval by the Company’s stockholders of a reorganization or merger unless, after such proposed transaction, the former stockholders of the Company will own more than 75% of the resulting corporation’s voting stock; or (iv) approval by the Company’s stockholders of a complete liquidation and dissolution of the Company or the sale or other disposition of substantially all of the assets of the Company, other than to a subsidiary or in a spin-off transaction. A “potential change-in-control” will generally be deemed to have occurred if (i) the Company enters into an agreement, the consummation of which would result in the occurrence of a change-in-control; (ii) any person (including the Company) publicly announces an intention to take action which, if consummated, would constitute a change-in-control; or (iii) any person (other than the Company, certain affiliated entities, or certain institutional investors) becomes the beneficial owner of 10% or more of the combined voting power of the Company’s then-outstanding securities.

The Rabbi Trust is irrevocable until participants and their beneficiaries are no longer entitled to payments under the covered plans and Agreements, but may be amended or revoked by agreement of the trustee, the Company, and a committee of individual beneficiaries of the Rabbi Trust.

Executive Compensation — Pay Ratio

Pay Ratio

The Dodd-Frank Act and the compensation disclosure rules of the SEC require us to disclose the ratio of the median of the annual total compensation of our employees (other than the Chief Executive Officer (the “CEO”)) and the annual total compensation of the CEO. For 2022, the median of the annual total compensation of all employees (other than the CEO) was $108,087 and the annual total compensation of the CEO was $17,068,131; accordingly, the CEO’s annual total compensation was approximately 158 times that of the median of the annual total compensation of all employees. This calculated “pay ratio” is a reasonable estimate determined in a manner consistent with SEC pay ratio disclosure requirements. We refer to the employee who received the median of the annual total compensation of all employees as the “median employee”.

We used the following methodology to make the determinations for calculating the pay ratio:

• |  | As of October 31, 2022, our employee population consisted of approximately 14,959 individuals (14,422 full-time and 537 other employees) working at our parent Company and consolidated subsidiaries, with 72% of these individuals located in the United States, 15% located in Europe (primarily Belgium, the Netherlands, and Germany), 10% located in Asia (primarily China, Malaysia, and Singapore) and 3% located in Latin America (primarily Mexico and Brazil).

| – |  | We selected October 31, 2022, as the date upon which we would identify the median employee to allow sufficient time to identify the median employee given the global scope of our operations.

• |  | To identify the median employee from our employee population, we conducted an analysis of our population of employees.

| – |  | Given the distribution of our employee population, we use a variety of pay elements to structure the compensation arrangements of our employees including participation in several annual cash short-term incentive plans. For purposes of measuring the compensation of all employees to determine the median employee, we selected total cash compensation (base salary for salaried employees and wages for hourly employees plus the most recent actual cash incentive payment for both hourly and salaried employees) as a consistently applied compensation measure that reasonably reflects the annual compensation of our employees.

| – |  | In making this determination, we annualized the compensation of all permanent employees who were hired in 2022.

• |  | Using this methodology, we determined that the median employee was a full-time, hourly, manufacturing operations employee with total compensation for 2022 consisting of wages, overtime pay, cash incentive payment, and annual Company contribution to defined contribution retirement plan determined and calculated in the same manner as compensation of the executive officers in the “Summary Compensation Table” earlier in this proxy statement.

• |  | The annual total compensation of the CEO is the amount reported for 2022 in the “Total” column of the “Summary Compensation Table.”

The SEC’s rules for identifying the median employee and calculating the pay ratio based on that employee’s annual total compensation allow companies to adopt a variety of methodologies, to apply certain exclusions, and to make reasonable estimates and assumptions that reflect their employee populations and compensation practices. As a result, the pay ratio reported by other companies may not be comparable to the pay ratio reported above, as other companies have different employee populations and compensation practices and may utilize different methodologies, exclusions, estimates, and assumptions in calculating their own pay ratios.

Item 3 — Advisory Approval of Executive

Compensation

The Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (the “Dodd-Frank Act”) provides stockholders with the right to vote to approve, on an advisory (nonbinding) basis, the compensation of the Company’s named executive officers as disclosed pursuant to the compensation disclosure rules of the SEC. This advisory vote is commonly referred to as the “say-on-pay” vote. In the Company’s advisory say-on-pay vote at the 2022 Annual Meeting, 92.4% of votes cast were “for” approval of the executive compensation. The Compensation Committee considers the outcome of this vote in its establishment and oversight of the compensation of the executive officers, as further discussed in “Executive Compensation — Compensation Discussion and Analysis”, and management continued to consider input of investors in its description of the terms of executive compensation and of the Compensation Committee’s executive compensation decisions in “Executive Compensation” as described in “Executive Compensation — Compensation Discussion and Analysis — Evaluation of Stockholder Say-on-Pay Vote Results and Investor Engagement.”

The Company’s strategy for business and financial growth from sustainable innovation, market engagement, and differentiated technologies and applications development leverages the capabilities of our employees to innovate and execute our growth strategy while remaining committed to maintaining a strong financial position with appropriate financial flexibility and liquidity. Our compensation philosophy supports this strategy by stressing the importance of pay for corporate and individual performance in meeting strategic and business goals for growth, innovative value creation, and financial strength and flexibility, while remaining able to meet changing employee, business, and market conditions. Our executive compensation program is designed to attract and retain a talented and creative team of executives who will provide disciplined leadership for the Company’s success in dynamic, competitive markets. The Company seeks to accomplish this by motivating executives with an appropriate mix of compensation elements to drive value for all stakeholders. Please read the “Executive Compensation — Compensation Discussion and Analysis” section of this proxy statement for additional details about our executive compensation philosophy and programs, including information about the compensation of our named executive officers for 2022 as detailed in the tables and narrative.

The say-on-pay vote gives stockholders the opportunity to indicate their views on the compensation of our named executive officers. This vote is not intended to address any specific item of compensation, but rather the overall compensation of our named executive officers and the philosophy, objectives, and practices described in this proxy statement.

Stockholders are being asked to approve the compensation of the named executive officers as disclosed in the “Executive Compensation” section of this proxy statement, including the Compensation Discussion and Analysis, compensation tables, and narrative. Because this vote is advisory, it will not be binding on the Compensation Committee, the Board, or the Company. However, the Compensation Committee and the Board value the opinions of the Company’s stockholders, and the Compensation Committee will consider the outcome of the vote in its establishment and oversight of the compensation of the executive officers.

|  | The Board recommends that you vote “FOR” the advisory approval of the compensation of the Company’s named executive officers as disclosed in this proxy statement.

2023 Proxy Statement 87

ITEM 4 — Advisory Vote on Frequency of Advisory

Approval of Executive Compensation

The Dodd-Frank Act provides stockholders with the right to vote, every six years, on an advisory (nonbinding) basis, on the frequency with which the Company should include a “say-on-pay” vote on executive compensation at future annual meetings of stockholders. The last such advisory vote on the frequency of say-on-pay votes was at the 2017 Annual Meeting of Stockholders.

At the Company’s 2017 Annual Meeting, 87.5% of votes cast in the advisory vote on the frequency of future say-on-pay votes were for such vote to occur every year, supporting the Board of Directors’ recommendation that say-on-pay be included in the Company’s proxy statement for, and be voted on by stockholders at, each annual meeting of stockholders. The Company has had a say-on-pay vote at each annual meeting of stockholders since the 2017 Annual Meeting.

The Board recommends that an advisory say-on-pay stockholder vote, similar to that contained in Item 3, continue to be included in the Company’s proxy statement for, and voted on by stockholders at, each annual meeting of stockholders. The Board believes that an advisory say-on-pay vote every year by stockholders provides the highest level of accountability and direct communication by having such vote correspond with the related information presented in the proxy statement for the applicable meeting of stockholders.

You may cast your vote on a preferred frequency with which the Company is to hold the advisory say-on-pay stockholder vote by selecting your preference of one year, two years, or three years, or abstaining from voting.

Because this vote is advisory, it will not be binding on the Board or the Company. Notwithstanding the results of such vote, and while the Company currently plans to continue to have an annual stockholder say-on-pay vote, the Board may decide that it is in the best interests of stockholders and the Company to hold an advisory vote on executive compensation more or less frequently than the preference chosen by the plurality (that is, the largest number) of votes cast by stockholders.

|  | The Board recommends that you vote for “ONE YEAR” on the advisory approval vote on executive compensation.

ITEM 5 — Advisory Vote on Stockholder Proposal

Regarding an Independent Board Chair

Stockholder John Chevedden, 2215 Nelson Avenue, No. 205, Redondo Beach, California 90278, owner of 50 shares of Eastman common stock, has given notice that he intends to submit the following proposal and supporting statement. The Company has reproduced the proposal and supporting statement as provided to the Company by stockholder John Chevedden and has not sought to correct or address all of the statements with which the Company disagrees:

Proposal 5 — Independent Board Chairman

Shareholders request that the Board of Directors adopt an enduring policy, and amend the governing documents as necessary in order that 2 separate people hold the office of the Chairman and the office of the CEO as follows:

Whenever possible, the Chairman of the Board shall be an Independent Director.

The Board has the discretion to select a Temporary Chairman of the Board who is not an Independent Director to serve while the Board is seeking an Independent Chairman of the Board.

Although it is a best practice to adopt this proposal soon, this policy could be phased in when there is a leadership transition.

This proposal topic won 52% support at Boeing and 54% support at Baxter International. Boeing then adopted this proposal topic in June 2020. The roles of Chairman and CEO are fundamentally different and should be held by 2 directors, a CEO and a Chairman who is completely independent of the CEO and our company.

Eastman Chemical is Exhibit A in why the Lead Director role is an empty suit compared to an independent Board Chairman.

Our so-called Lead Director, Mr. David Raisbeck violates the most important attribute of a Lead Director — independence. As director tenure goes up director independence goes down. Mr. Raisbeck has 23-years of excessive director tenure. And Mr. Raisbeck has not had a day job for 15-years. Mr. Raisbeck’s long tenure makes him a prime candidate to retire. It is time for a change.

A lead director is no substitute for an independent board chairman. With the current CEO serving as Chair this means giving up a substantial check and balance safeguard that can only occur with an independent Board Chairman. A lead director cannot call a special shareholder meeting.

A lead director can delegate many details of his lead director duties to others and then simply rubber-stamp it. Management has not explained how shareholders can be sure of what goes on in regard to lead director delegation.

A lead director with long tenure can also give excessive deference to the Eastman Chemical CEO.

The increased complexities of companies of more than $10 Billion in annual revenue, like Eastman Chemical, demand that 2 persons fill the 2 most important jobs in the company.

Please vote yes:

Independent Board Chairman — Proposal 5

2023 Proxy Statement 89

Executive Compensation — Termination and Change-in-Control Arrangements

Response of the Company

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE AGAINST THIS PROPOSAL

The Board of Directors has carefully considered the stockholder proposal and unanimously believes that the action requested by this proposal is unnecessary and not in the best interests of the Company or its stockholders.

The Board should be able to select its leadership structure — including its Chair and CEO — based upon its determination of the structure that best serves the interests of stockholders. The Board believes that our stockholders’ interests are best served when we retain the ability to select the appropriate person to serve in the Chair role and that our current leadership structure is effective in its independent oversight of Eastman.

As described in “Board Leadership Structure” on page 28, Chief Executive Officer and director Mark J. Costa has served as Chair since 2014, the Board having determined that this is the most efficient manner to facilitate effective communication between management and the Board and provide strong and consistent leadership as well as a unified voice for the Company. In addition, the Board believes that combining the roles of Chair and Chief Executive Officer helps ensure that the Chief Executive Officer understands and can effectively and efficiently manage the implementation of the recommendations and decisions of the Board.

Our Lead Director Provides Meaningful Independent Leadership and Oversight at the Board Level. In order to give a significant voice to our non-employee, independent directors and to reinforce effective, independent leadership on the Board, the Company’s Bylaws and Corporate Governance Guidelines provide that the Company shall have an independent Lead Director if the same person holds the Chief Executive Officer and Chair positions or if the Chair is not otherwise independent.

Contrary to the proponent’s various assertions about the powers of a lead director, none of which are specific to Eastman, the Company’s Lead Director has substantial authority and helps ensure appropriate oversight of the Chief Executive Officer by the independent directors. The Lead Director’s responsibilities, which are described in more detail in the Company’s Corporate Governance Guidelines, include:

| • |  | calling, setting agendas for, and presiding over executive sessions of the non-employee, independent directors at each regularly scheduled meeting of the Board, or at such other times as the non-employee, independent directors may determine;

| • |  | calling special meetings of the full Board or the non-employee, independent directors;

| • |  | presiding over Board meetings in the absence of the Chair;

| • |  | collaborating and consulting with Committee chairs concerning schedules, agendas, and written materials;

| • |  | acting as a liaison between the independent directors and the Chair; and

| • |  | being available with the Chair for consultation and direct communication with stockholders.

The governance concerns expressed by the proponent are unfounded and do not reflect the Company’s leadership and governance practices. The proponent makes a number of inaccurate and/or unfounded assertions about the Company’s governance and, in particular, our Lead Director. Among these is the assertion that our independent Lead Director “violates the most important attribute of a Lead Director — independence” because of his years of service on the Board. This is not the case. In fact, Mr. Raisbeck is independent under all applicable independence standards. Mr. Raisbeck’s years with the Company and experience enable him to bring valuable and independent views to the boardroom, where he provides thoughtful leadership for both fellow directors and senior management.

90 2023 Proxy Statement

Item 5 — Advisory Vote on Stockholder Proposal Regarding an Independent Board Chair

The proponent further asserts that Mr. Raisbeck’s “long tenure makes him a prime candidate to retire.” Our Corporate Governance Guidelines set forth the standard for director retirement, under which a director will not be eligible for nomination, appointment, or election (or re-election) to the Board. Mr. Raisbeck’s continued role on the Board is entirely consistent with the Company’s Corporate Governance Guidelines and, moreover, he has continuously received strong support from stockholders in his annual election to the Board, including 93.62% support at the 2022 Annual Meeting. In addition, the Lead Director is nominated and elected by the non-employee, independent directors on an annual basis. Eastman also has a history of rotating the Lead Director every three to five years. Mr. Raisbeck has been Lead Director since May 2020.

Finally, the proponent asserts that a lead director can “delegate many details of his lead director duties to management and then simply rubber-stamp it.” As described above, the Lead Director’s duties are set out in the Company’s Corporate Governance Guidelines, which are readily available on the Company’s website, and which include no express provisions for delegation of the Lead Director’s duties to management.

We have implemented strong corporate governance practices and regularly review and update these practices as appropriate. Eastman maintains strong corporate governance practices, which assure management accountability and effective independent oversight. Among other things, all Eastman directors, with the exception of the CEO, meet the independence requirements of the New York Stock Exchange, and the Board’s standing Committees are each chaired by independent directors and are 100% independent. Directors are elected annually and, as described above, the Company has a Lead Director with clear and substantive authority and responsibilities.

The Board maintains its demonstrated commitment to corporate governance policies that are in the best interests of the Company and its stockholders by regularly reviewing the Company’s governance structure, policies, and practices, including considering input from stockholders and others.

Consistent with its commitment to strong corporate governance, over the years, the Board has made changes to the Company’s governance structure, policies, and practices that it determined to be in the best interests of the Company and its stockholders. Past changes include the adoption of a proxy access bylaw provision that allows qualifying stockholders to include their director nominees in the Company’s proxy materials and a Board stockholder communication and engagement policy. Past changes also include the implementation of majority voting in the election of directors, repeal of the Company’s “poison pill” stockholder rights plan, declassification of the Board, implementation of the existing right of stockholders to call special meetings, and removal of certain supermajority voting requirements from the Company’s Certificate of Incorporation and Bylaws. Most recently, changes to the composition of the Board of Directors have significantly reduced the average tenure of the directors.

These actions demonstrate that the Board is not reluctant to make changes in its governance practices when it determines that a change is in the best interests of the Company and its stockholders. The requested change to a fixed policy requiring a separation of the roles of Chair and CEO is not, however, such a change.

Given the strong leadership of the Company’s Chair and CEO, the counter-balancing role of the Lead Director and a Board comprised of experienced and independent directors, the Board continues to believe it is in the best long-term interests of the Company and its stockholders to maintain the combined role of Chair and CEO.

Director and Executive Stock Ownership Expectations; No Hedging or Pledging of Company Stock

Eastman has stock ownership expectations for its directors and executive officers. These persons are expected to acquire and maintain a stake in the Company valued at $600,000 for non-employee directors (five times annual retainer fee), five times annual base pay for the Chief Executive Officer, and two and one-half times annual base pay for the other executive officers. Directors and executive officers are expected to attain these levels of stock ownership within five years of first becoming a director or an executive officer. Hypothetical units of the Eastman common stock fund that are credited to an executive’s account under the EDCP and to a director’s account under the DDCP are counted with shares of common stock actually owned for purposes of determining stock ownership under the director and executive ownership expectations. See “Director Compensation — Directors’ Deferred Compensation Plan” and “Executive Compensation — Compensation Tables — 2022 Nonqualified Deferred Compensation”.

ADDITIONAL INFORMATION ABOUT THE ANNUAL

MEETING

What Is A Proxy Statement, and How Do I Attend and Vote at the Annual Meeting?

A. This proxy statement is dated March 22, 2023, and is first being mailed and delivered electronically to Eastman stockholders, and made available on the Internet at the Company’s website (www.eastman.com) and at www.ReadMaterial.com/EMN, on or about March 22, 2023. Our Board is furnishing you this proxy statement in connection with its solicitation of proxies to be voted at the 2023 Annual Meeting of the Company to be held on May 4, 2023, and at any adjournments or postponements of the meeting. A proxy statement is a document that SEC regulations require us to give you when we ask you to vote your stock by proxy. At the meeting, stockholders will be asked to consider and vote on the items of business listed and described in this proxy statement.

We have decided to hold our Annual Meeting virtually on the Internet via live webcast. Stockholders will be able to attend and participate online. We have structured our virtual meeting to provide stockholders the same rights as if the meeting were held in person, including the ability to vote shares electronically during the meeting and submit questions in advance of and during the meeting in accordance with the rules of conduct for the meeting. The rules of the meeting and other information about participation and voting will be available in the Annual Meeting section of our website. As always, we encourage you to submit a proxy to vote your shares prior to the Annual Meeting so that your shares will be represented and voted at the meeting whether or not you attend virtually.

To attend the Annual Meeting virtually, stockholders must register using their control number and other information to identify such stockholder, at https://register.proxypush.com/emn. Upon completing registration, stockholders will receive further instructions by e-mail, including links that will allow them to access the Annual Meeting, vote online, and submit questions. If you are a beneficial stockholder, you may contact the bank, broker, or other institution where you hold your account if you have questions about obtaining your control number.

The Annual Meeting will begin promptly at 11:30 a.m. (EDT) on May 4, 2023, though stockholders may log-in beginning at 11:15 a.m. (EDT). We encourage you to access the Annual Meeting prior to the start time.

The Annual Meeting virtual platform is fully supported across browsers (Edge, Firefox, Chrome, and Safari) and devices (desktops, laptops, tablets, and cell phones) running the most updated version of applicable software and plugins. Stockholders should ensure that they have a strong internet connection if they intend to attend or vote at the Annual Meeting. Attendees should allow plenty of time to log-in and ensure that they can hear streaming audio prior to the start of the Annual Meeting. Additional information regarding the rules of conduct and other materials for the Annual Meeting will be available, via link, during the Annual Meeting. In addition, we will make available a list of stockholders of record as of the record date for inspection by stockholders for any purpose germane to the Annual Meeting for ten days preceding the Annual Meeting.

Additional Information About the Annual Meeting

What is a Proxy, and How do I Vote by Proxy at the Annual Meeting?

A. A proxy is a legal designation of another person to vote stock you own. That other person is called a proxy. If you designate someone as your proxy in a written or electronic document, that document is also called a proxy, a proxy card, or a form of proxy.

By completing and returning your proxy (either by returning the paper proxy card, by submitting your proxy electronically by Internet, or by telephone), you appoint William T. McLain, Jr., the Company’s Chief Financial Officer, and Kellye L. Walker, the Company’s Corporate Secretary, to represent you at the Annual Meeting and direct them to vote your shares at the Annual Meeting. Shares of common stock represented by proxy will be voted by the proxy holders at the Annual Meeting in accordance with your instructions as indicated in the proxy. If you properly execute and return your proxy (in paper form, electronically by the Internet, or by telephone) but do not indicate any voting instructions, your shares will be voted in accordance with the recommendations of the Board as to the matters identified in this proxy statement and in the best judgment of the proxy holders as to any other matters.

If your shares are registered in your name, you are a stockholder of record. Stockholders of record may vote by proxy in one of three ways:

By Internet: visit the website www.cesvote.com and follow the instructions on your proxy card or electronic form of proxy. |  |  |  |  |  | By telephone: call (888) 693-8683 and follow the instructions on your proxy card or electronic form of proxy. |  |  |  |  |  | By mail (if you received a paper proxy card): mark, sign, date, and mail your proxy card in the enclosed postage-paid envelope.

If you received the “Important Notice Regarding the Availability of Proxy Materials”, follow the instructions on that notice to access an electronic form of proxy. Internet and telephone voting procedures are designed to authenticate stockholder identities, to allow stockholders to give voting instructions, and to confirm that stockholders’ instructions have been recorded properly.

If your shares are held in “street name” through a broker, bank, or other holder of record, you will receive instructions from that registered holder that you must follow in order for your shares to be voted for you by that record holder. Telephone and Internet voting may be offered to stockholders who own their shares through certain brokers or banks.

If stockholders submit a proxy to vote their shares prior to the Annual Meeting, their shares will be voted at the Annual Meeting according to their instructions and they do not need to vote their shares at the Annual Meeting. Whether or not you plan to attend the Annual Meeting, we urge you to vote in advance of the Annual Meeting by proxy in one of the ways described above.

How Do I Revoke My Proxy?

A. Stockholders of Record: If you give a proxy, you may revoke it at any time before its exercise at the meeting by:

• |  | giving written notice of revocation to the Corporate Secretary of the Company;

• |  | executing and delivering a later-dated, signed proxy card or submitting a later-dated proxy by Internet or by telephone before the meeting; or

• |  | voting in person virtually at the meeting.

All written notices of revocation or other communications with respect to revocation of proxies should be sent to Eastman Chemical Company, P.O. Box 431, Kingsport, Tennessee 37662-0431, Attention: Corporate Secretary, so that they are received before the Annual Meeting.

2023 Proxy Statement 97

Additional Information About the Annual Meeting

Beneficial Owners: If you are a beneficial owner of your shares, you must contact the bank, broker, or other nominee holding your shares and follow their instructions for revoking or changing your vote.

What is the Record Date for the Annual Meeting? Which Stockholders Are Entitled to Vote?

A. The record date for the 2023 Annual Meeting is March 15, 2023. Stockholders of record of common stock at the close of business on the record date are entitled to receive notice of the meeting and to vote at the meeting. The record date is established by the Board as required by Delaware law. If your shares are held in “street name” through a broker, bank, or other holder of record, you must obtain a proxy, executed in your favor, from the holder of record to be able to vote in person virtually at the meeting.

On the record date, there were 119,138,025 shares of common stock issued and outstanding. Holders of common stock are entitled to one vote on each of the twelve director-nominees and one vote on each other matter voted upon at the Annual Meeting for each share of common stock they hold of record on the record date.

What is A Quorum to Conduct Business at the Meeting? How Are Abstentions and Broker

Non-Votes Counted at the Annual Meeting?

A. The presence, in person virtually or by proxy, of the holders of a majority of the shares of common stock entitled to vote at the Annual Meeting is necessary to constitute a quorum to conduct business. Abstentions and “broker non-votes” will be counted as present and entitled to vote for purposes of determining a quorum. A “broker non-vote” occurs when a registered holder holding shares in “street name” for a beneficial owner does not vote on a particular proposal because the registered holder does not have discretionary voting power for that particular item and has not received voting instructions from the beneficial owner. Brokers which have not received voting instructions from their clients cannot vote on their clients’ behalf on the election of directors, the advisory approval of executive compensation, the advisory vote on the frequency of the vote on executive compensation, or the advisory vote on the stockholder proposal, but may, although they are not required to, vote their clients’ shares on the ratification of the appointment of the independent registered public accounting firm.

What Votes Are Required for Approval of the Matters to be Considered at the Annual

Meeting?

A. Each director nominee who receives a majority of votes cast (number of shares voted “for” exceeds 50% of the number of votes cast with respect to that director’s election) will be elected as a director. With respect to the election of directors, stockholders may (1) vote “for” all twelve of the nominees, (2) vote “against” all twelve of the nominees, (3) vote “against” any individual nominee or nominees but vote “for” the other nominee(s), or (4) “abstain” from voting on one or more nominees. Shares not present, in person or by proxy, at the Annual Meeting and abstentions will have no effect on the outcome of the election of directors. Similarly, broker non-votes will not be considered to be votes cast and therefore will have no effect on the outcome of the election of directors.

The affirmative vote of a majority of the votes cast is required for the ratification of the appointment of the independent registered public accounting firm, the advisory approval of executive compensation, the advisory approval of the frequency of the vote on executive compensation, and the advisory vote on the stockholder proposal. With respect to each of these items other than the advisory approval of the frequency of the vote on executive compensation, stockholders may (1) vote “for,” (2) vote “against,” or (3) “abstain” from voting. With respect to the advisory approval of the frequency of the vote on executive compensation, stockholders may (1) vote for “one year”, (2) vote for “two years”, (3) vote for “three years”, or (4) “abstain” from voting. Abstentions and broker non-votes will not be considered to be votes cast and therefore will have no effect on the outcome of the vote on these matters.

Additional Information About the Annual Meeting

What Are Proxy Solicitation Costs, and Who Pays Them?

A. We will bear the cost of soliciting proxies and the cost of the Annual Meeting. In addition to the solicitation of stockholders by mail and electronic means, proxies may be solicited by telephone, facsimile, personal contact, and similar means by our directors, officers, or employees, none of whom will be specially compensated for these activities. We have also contacted brokerage houses, banks, nominees, custodians, and fiduciaries which can be identified as record holders of common stock. Such holders, after inquiry by us, have provided certain information concerning beneficial owners not objecting to the disclosure of such information and the quantities of proxy materials and annual reports needed to supply such materials to beneficial owners, and we will reimburse such record holders for the expense of providing such beneficial ownership information and of mailing or otherwise delivering proxy materials and annual reports to beneficial owners. We have retained Georgeson LLC to assist with the solicitation of proxies and vote projections for a fee of $20,500 plus reimbursement of out-of-pocket expenses.

What About Matters Not Included in This Proxy Statement?

A. We do not expect any business to be acted upon at the Annual Meeting other than as described in this proxy statement. If, however, other matters are properly brought before the Annual Meeting, the persons appointed as proxies will have the discretion to vote or act on those matters for you according to their best judgment.

What Is the Deadline for Submission of Stockholder Proposals for the 2024 Annual Meeting

of Stockholders?

A. In accordance with the rules of the SEC, if you wish to submit a proposal for presentation at Eastman’s 2024 Annual Meeting of Stockholders, it must be received by the Company at its principal executive offices no later than November 23, 2023, in order to be included in the Company’s proxy materials for its 2024 Annual Meeting of Stockholders under SEC Rule 14a-8. Any such proposal should be sent to Eastman Chemical Company, P.O. Box 431, Kingsport, Tennessee 37662-0431, Attention: Corporate Secretary.

The Bylaws are available through the “Investors — Governance” section of the Company’s website, and also will be provided to any stockholder upon written request to Eastman Chemical Company, P.O.

What Are the Requirements for Nominations by Stockholders for Election to the Board of

Directors and Stockholder Nomination Proxy Access?

100 2023 Proxy Statement

ANNEX A

Reconciliation of Non-GAAP Financial Measures

Company GAAP and Non-GAAP Performance 2022 verses 2021

Non-GAAP financial measures, and the accompanying reconciliations of the non-GAAP financial measures to the most comparable GAAP measures, are presented below.

(In millions, except per share amounts) |  | 2022 |  |  | 2021 |
Sales revenue |  | $ | 10,580 |  |  | $ | 10,476 |
Earnings before interest and taxes (“EBIT”) |  | $ | 1,159 |  |  | $ | 1,281 |
Adjusted EBIT* |  | $ | 1,339 |  |  | $ | 1,635 |
Earnings per diluted share |  | $ | 6.35 |  |  | $ | 6.25 |
Adjusted earnings per diluted share* |  | $ | 7.88 |  |  | $ | 8.85 |
Net cash provided by operating activities |  | $ | 975 |  |  | $ | 1,619 |

* | For non-core or unusual items excluded from adjusted earnings and for adjusted provision for income taxes, and reconciliations to reported company earnings and to cash provided by operating activities for all periods presented, see Tables 1 and 2 below.

We provide non-GAAP financial measures in the proxy statement, and the related reconciliations to the most comparable GAAP financial measures, because we believe our stockholders use these metrics in evaluating longer term period-over-period performance, and to allow stockholders to better understand and evaluate the information used by us to assess the Company’s performance, make resource allocation decisions, and evaluate organizational and individual performances in determining certain performance-based compensation. Non-GAAP financial measures do not have definitions under GAAP, and may be defined differently by, and not be comparable to, similarly titled measures used by other companies. As a result, we caution stockholders not to place undue reliance on any non-GAAP financial measure, but to consider such measures alongside the most directly comparable GAAP financial measure.

Because non-core, unusual, or non-recurring transactions, costs, and losses or gains may materially affect the Company’s financial condition or results in a specific period in which they are recognized, management believes it is appropriate to evaluate the financial measures prepared and calculated in accordance with both GAAP and the related non-GAAP financial measures excluding the effect on the Company’s results of these non-core, unusual, or non-recurring items. In addition to using such measures to evaluate results in a specific period, management evaluates such non-GAAP measures, and believes that investors may also evaluate such measures, because such measures may provide more complete and consistent comparisons of the Company’s, and its segments’, operational performance on a period-over-period historical basis and, as a result, provide a better indication of expected future trends.

2023 Proxy Statement A-1

ANNEX A — Reconciliation of Non-GAAP Financial Measures

Non-Core Items or any Unusual or Non-Recurring Items Excluded from Non-GAAP Earnings

In addition to evaluating Eastman’s financial condition, results of operations, liquidity, and cash flows as reported in accordance with GAAP, management also evaluates Company and operating segment performance, and makes resource allocation and performance evaluation decisions, excluding the effect of transactions, costs, and losses or gains that do not directly result from Eastman’s normal, or “core”, business, and operations, or are otherwise of an unusual or non-recurring nature.

• |  | In 2022, the Company recognized unusual costs, net of insurance proceeds, from the previously reported January 31, 2022 operational incident at its Kingsport site as a result of a steam line failure (the “steam line incident”). Management considered the operational incident unusual because of the Company’s operational and safety history and the magnitude of the unplanned disruption.

• |  | In 2021, the Company decreased the provision for income taxes due to adjustment of the amount recognized in prior years resulting from the 2017 Tax Cuts and Jobs Act (“Tax Reform Act”). As with the prior years’ item to which this relates, management considers this decrease unusual because of the infrequent nature of the underlying change in tax law and resulting impacts on earnings.
