Aflac (NYSE: AFL) 2026 proxy details pay, board and chair proposal vote

Rhea-AI Filing Summary

Aflac Incorporated is asking shareholders to vote at its virtual 2026 annual meeting on four key items: electing eleven directors, an advisory say-on-pay, ratifying KPMG LLP as auditor for 2026, and a shareholder proposal seeking an independent board chair, which the Board recommends voting against.

The proxy highlights 2025 performance, with net earnings of $3.6B, earnings per diluted share of $6.82 and return on equity of 13.1%. Adjusted earnings ex‑FX were $4.0B and adjusted EPS ex‑FX $7.46, with adjusted ROE ex‑FX of 17.5%. Aflac raised its cash dividend 16.0%, repurchased $3.5B of shares and delivered three‑year total shareholder return of 63.8%.

The Board emphasizes a largely independent slate (91% of nominees), diverse skills including Japanese market, risk and digital expertise, and a long-standing pay‑for‑performance program. Say‑on‑pay received 96.6% support in 2025 and has averaged 96.4% over five years.

LETTER FROM THE CHAIRMAN AND CHIEF EXECUTIVE OFFICER

March 19, 2026

Dear Fellow Shareholders:

I am very proud that 2025 was yet another year in our seven-plus decade history that our management, employees and sales distribution teams pressed on as dedicated champions of our business to accomplish our goal: providing the best value in supplemental insurance products in the United States and Japan. Reflecting on 2025, the Company proudly celebrated three notable milestones: the 70th year since our founding, the 30th anniversary of the Aflac Cancer and Blood Disorders Center of Children’s Healthcare of Atlanta, and the 25th anniversary of the Aflac Duck. Each of these noteworthy achievements demonstrates the relevance and fortitude of the financial protection Aflac products help provide. But it’s not the number of years that make a difference – it’s the privilege of benefiting the lives of millions of people by delivering financial protection and peace of mind during some of the most difficult times of their lives. It is important that we look back to learn, but looking ahead is what will yield our future. As the pioneer and leading insurer of supplemental cancer policies in the U.S. and Japan – and given that cancer impacts such a significant segment of the population in both countries – we understand that people look to Aflac to set the tone and build out an ecosystem of support in the U.S. and Japan. This purpose guided our 2025 efforts to prompt awareness and actionable prevention on numerous fronts. In the U.S., we strengthened our alliance with the American Cancer Society to help provide our policyholders with awareness of the support they have as they go through their treatment journey. In 2025, we also created Check for Cancer, Aflac U.S.’s powerful movement that uses a blue checkered pattern to remind Americans to “check” on what’s important through cancer screening appointments. This is especially vital given the recent increase in younger people diagnosed with this disease, underscored by the fact that early detection is still our best line of defense against cancer at any age. In Japan, we offer Miraito, our latest cancer policy launched in March 2025. With that product, we offer Yori-sou Cancer Consultation Support, a special value-added service through which customers can access unlimited consultations with a dedicated support team, including qualified nurses, who help them make informed treatment decisions. Growth: While delivering value to our policyholders, the Company generated $3.6 billion in net earnings, or $6.82 per diluted share, in 2025. As a result, net earnings per diluted share declined 29.2%. Adjusted earnings per diluted share* were $7.49, the best year in history, and adjusted earnings per diluted share excluding the impact of foreign currency* were $7.46, which was a 3.5% increase year over year. While our financial results were strong, we are ever-cognizant of considering ways to evolve and improve our business. In Japan, in addition to our successful March 2025 launch of Miraito that followed the restructuring of sales/marketing in Japan into multi-functional, agile teams around product lines, we repriced Tsumitasu, our innovative first sector product in September, as part of our effort to attract new and younger customers to our third sector policyholders while addressing their need for asset accumulation products. Then, in late December, we launched the new medical product Anshin Palette as we try to build momentum into 2026. Strategic Capital Deployment: 2025 marked the 43rd consecutive year of dividend increases. We treasure our track record of dividend growth and remain committed to extending it, supported by the strength of our capital and cash flows. Last quarter, the Board put us on a path to continue this record when it increased the first quarter 2026 dividend 5.2% to $0.61. Additionally, we have remained tactical in our approach to repurchasing shares, deploying $3.5 billion in capital to repurchase 33 million of our shares in 2025. Combined with dividends, this means we delivered $4.8 billion back to shareholders in 2025. At the same time, we have maintained our position among companies with the highest return on capital and lowest cost of capital in the industry. We are privileged to be stewards of the trust and resources you, our owners, place in Aflac Incorporated. We thank you for your support. It is my pleasure to invite you to virtually attend the 2026 Annual Meeting of Shareholders on Monday, May 4, 2026, where you can learn more about Aflac Incorporated’s recent business performance and strategy for the future. I encourage you to review the proxy materials and Annual Report on Form 10-K. Then, please vote your shares, even if you plan to attend the virtual Annual Meeting. We want to be sure your shares and your viewpoints are represented. Sincerely, Daniel P. Amos Chairman and Chief Executive Officer

*      Adjusted earnings per diluted share and adjusted earnings per diluted share excluding foreign currency impact are not calculated in accordance with generally accepted accounting principles in the United States (GAAP). See Appendix A to this Proxy Statement for the definition of these non-GAAP measures and reconciliation to the most comparable GAAP financial measure.

2026 PROXY STATEMENT 3

LETTER FROM THE LEAD NON-MANAGEMENT DIRECTOR

March 19, 2026

Dear Fellow Shareholders:

It is a privilege to serve you, our shareholders, as Lead Non-Management Director, in conjunction with a distinguished and dedicated team of Directors. This team has incrementally built a valuable and diversified framework of reference from which we can draw. As Directors, we take seriously our responsibility to represent the interests of you, our shareholders. This letter highlights some of the key topics of oversight in 2025. Risk Oversight: Our Board provided oversight of the more traditional risks for the industry and the Company, including those related to investments, products and capital. The Board's Audit and Risk Committee monitored cybersecurity risks, including through quarterly updates from senior officers. The Company and our Management team's preparedness activities allowed for a timely response to a June 2025 cybersecurity incident impacting a limited number of Company systems, with removal of the threat actors within hours. In addition, artificial intelligence (“AI”) was a very frequent topic in our discussions in 2025 and remains so today. The Board has continued to oversee the Company’s efforts on risk oversight through its quarterly updates. Corporate Finance and Investments: The Aflac Global Investments team has built a high-quality, all-weather portfolio that we believe supports our promise to our policyholders no matter the economic environment. In 2025, our investment portfolio continued to benefit from our disciplined strategic asset allocation, which is refreshed every three years. Additionally, in 2025 the Capital Markets team enhanced the Company’s liquidity and capital flexibility with the largest combined issuance in its history ($2 billion), with our first off-balance sheet, pre-capitalized trust securities, commonly referred to as P-Caps. Strategic Initiatives: Looking ahead, we believe in the underlying strengths of the Company’s business and potential for continued growth in Japan and the U.S. – two of the largest life insurance markets in the world. Management has worked hard to position the Company for opportunities and success as we work toward achieving long-term growth while also ensuring we deliver on our promise to policyholders. The Board continually works closely with management to help ensure the Company has updated processes in place that position us to pursue potential future opportunities, should the Company have an appetite, as we seek new ways to meet the needs of consumers. Commitment to working The Aflac Way: The journey matters too. Most recently, Ethisphere recognized Aflac Incorporated as one of the World’s Most Ethical Companies for the 20th consecutive year, meaning we remain the only insurance company in the world to receive this honor every year since it was first introduced in 2007. As a Director and a shareholder, I am proud to be connected with a company that not only consistently benefits its shareholders, but in doing so, receives positive recognition for the way in which it operates. Shareholder Engagement: As Lead Non-Management Director, I will continue to engage with our investors, seek insight into their perspectives, and explore the viewpoints and positions of those who invest in our business. The Board looks forward to continuing its ongoing dialogue with investors and applying that feedback to help inform our decision making on strategic matters as they emerge. A shareholder proposal has been submitted this year, and the Company engaged with the proponent prior to the publication of the proxy statement. We thank you for your support and the privilege of representing you as shareholders of Aflac Incorporated. With these vital topics in mind, I encourage you to review the accompanying Proxy Statement and Annual Report on Form 10-K as well as Aflac Incorporated’s most recent Business and Sustainability Report, and to vote before our virtual Annual Meeting on May 4, 2026. It is my pleasure, and my privilege, to serve on Aflac Incorporated’s Board. I can assure you, your Board is committed to serving you and ensuring your Company upholds our promises to our customers. Sincerely, W. Paul Bowers Lead Non-Management Director

Executive Compensation Highlights

Our executive compensation philosophy is to provide pay that is aligned with the Company’s results. We believe this is the most effective method for creating shareholder value and it has played a significant role in making the Company an industry leader. Our executive compensation program is designed to align pay and performance, generally targets market median positioning, and delivers the majority of direct compensation through performance-based elements. This helps ensure proper alignment with our shareholders and ties compensation for named executive officers (NEOs) to the Company’s performance on key financial and strategic metrics.

The Company’s executive compensation program reflects our corporate governance best practices principles:

Independent Oversight			•The Board’s independent Compensation Committee oversees the program. •The Compensation Committee retains an independent compensation consultant that reports only to that Committee. •The independent compensation consultant briefs the full Board annually on CEO pay and performance alignment.
Shareholder Alignment			•All employees are prohibited from hedging Company stock. •Officers and Directors may not pledge the Company’s stock or, unless approved by the Compensation Committee, enter into 10b5-1 plans. •We do not provide change-in-control excise tax gross-ups. •All employment agreements contain double trigger change-in-control requirements.
Long-Standing Commitment			•We have had a clawback policy since 2007, which was recently revised to exceed current regulatory requirements through inclusion of additional triggers for recoupment. •We were the first public company in the U.S. to voluntarily provide shareholders with a Say-on-Pay vote – three years before such votes became mandatory. •Executive officers and Directors have been subject to stock ownership guidelines since 1998.

2025 Executive Compensation

The total target direct compensation mix for 2025 for (1) our CEO and (2) the average of our other NEOs is illustrated in the following charts and reflects the performance-based nature of our compensation program:

Recent Say-On-Pay Votes

We are pleased that our named executive compensation program received the voting support of over 96% of our shareholders in 2025, in line with the high support we have received over the past five years. We believe this continued support reflects positively on our executive compensation program, which links compensation metrics to our business strategy while incorporating feedback received from our shareholders. We work hard to implement best practices in executive compensation while staying focused on performance-based program elements that align with shareholder interests. We will continue to review our compensation program each year to determine if additional changes are warranted.

Election of Directors Each Director stands for election annually. The Directors up for election at the Annual Meeting are named in this Proxy Statement. The following provides summary information about the nominees. Our Board believes it is appropriate to maintain a balance of longer tenured members, who bring stability and valuable Company-specific knowledge with a historical perspective, and newer members, who bring fresh viewpoints and new ideas.

The Board of Directors recommends a vote FOR each of the eleven  nominees named in this Proxy Statement.

The Company proposes that the eleven individuals named in this Proxy Statement be elected to the Board. These individuals have been nominated by the Board’s Corporate Governance Committee. If elected, they are willing to and expected to serve for a one-year term expiring at our 2027 Annual Meeting of Shareholders. Each Director will hold office until his or her successor has been elected and qualified or until the Director’s earlier death, resignation, or removal. The people named in the accompanying proxy (or their substitutes) will vote to elect these nominees unless specifically instructed to the contrary. However, if any nominee becomes unable or unwilling to serve or is otherwise unavailable for election, the people named in the proxy (or their substitutes) will have discretionary authority to vote or to refrain from voting on any substitute nominee. The Board has no reason to believe that any of the nominees will be unable or unwilling to serve if elected.

All of the nominees are currently members of our Board.

We expect all of our Directors to have a demonstrated ability to make a meaningful contribution to the Board’s oversight of the business and affairs of the Company. As shown below and on the following pages, our nominees have a range of skills and experience in areas that are critical to our industry and our operations.

Katherine T. Rohrer VICE PROVOST EMERITUS, PRINCETON UNIVERSITY

Director Independence The Board annually assesses the independence of each Director and Director nominee. Daniel P. Amos is an employee of the Company. The Board has determined that all of the other Directors during the last completed fiscal year and Director nominees are “independent” under New York Stock Exchange (“NYSE”) listing standards. None of the independent nominees has a material relationship with the Company, either directly or as a partner, shareholder, or officer of an organization that has a relationship with the Company. The Board made its determination based on information furnished by all Directors regarding their relationships with the Company and research conducted by management. Board Succession Planning and Refreshment Process Our Board believes it is appropriate to maintain a balance of longer tenured members, who bring stability and valuable Company-specific knowledge with a historical perspective, and newer members, who bring fresh viewpoints and new ideas. Pursuant to the Company’s Guidelines on Significant Corporate Governance Issues, independent directors will not be nominated for a term that would begin after the director’s 75th birthday. Our regular self-evaluation process is designed to ensure we maintain a cohesive and well-constituted board of high integrity that exemplifies the right balance of perspectives, experience, independence, skill sets, and subject matter experts required for prudent oversight. Over the last five years, we have added three new director nominees as we prioritize candidates with the skills needed to provide effective oversight.

Director Nominating Process

Our Corporate Governance Committee is responsible for establishing criteria, screening candidates and evaluating the qualifications of persons who may be considered for service as a Director.

1			SUCCESSION PLANNING
The Committee considers the current and long-term needs of our business and seeks potential candidates in light of evolving needs, current Board structure, tenure, demographics, skills, and experience.
2			IDENTIFICATION OF CANDIDATES
The Committee may identify potential candidates from three sources:    suggestions from current Directors and executive officers;    firms that specialize in identifying director candidates; and/or    as discussed below, candidates recommended by shareholders.
3			THRESHOLD QUALIFICATIONS
The Committee believes that, at a minimum, nominees for Director must have:   a demonstrated ability to make a meaningful contribution to the Board’s oversight of the business and affairs of the Company; and    an impeccable record and reputation for honest and ethical conduct in both professional and personal activities.
4			ADDITIONAL QUALIFICATIONS
The Committee strives to build a Board that is strong in its collective knowledge. Among other skill sets, the Committee looks for nominees with experience in the following areas:
accounting and finance    management and leadership    vision and strategy						business operations   business judgment    industry knowledge			corporate governance   global markets    communication
In addition, the Committee assesses candidates for impeccable values and ethical standards, and considers the broad range of backgrounds, skills, disciplines, expertise, experiences, and opinions that are desirable within the context of the characteristics and needs of the Board as a whole. Directors may sit on no more than four public company boards (including our own) or no more than one additional public company board if the Director is an officer of the Company. All of our Director nominees currently comply with our policy on outside board service. The Committee reviews requests from Directors to serve on the board of other public companies.
5			MEETING WITH CANDIDATES
Once the Committee identifies one or more potential nominees, its members:   review publicly available information and contact candidates who warrant further consideration;   request further information for those potential nominees willing to be considered for a Board seat;   conduct one or more interviews with each potential nominee; and   may contact references provided by candidates and speak with members of the business community or other people who have firsthand knowledge of a candidate’s record.
This process enables the Committee to compare the accomplishments and qualifications of all potential nominees.
6			DECISION AND NOMINATION
The Committee nominates the candidates best qualified to serve the interests of the Company and all shareholders for approval by the Board.
7			ELECTION
Shareholders consider the nominees and elect Directors at the Annual Meeting of Shareholders to serve one-year terms. The Board may also appoint Directors during the year when determined to be in the best interests of the Company and its shareholders.

Director Renomination

The criteria for renomination is substantially similar to that for new nominations. In addition, the Corporate Governance Committee considers independence; the Director’s ability to commit the necessary time and attention appropriate for effective Board service; past attendance at meetings; contributions to the Board and committees on which the Director serves; the knowledge, experience, skills, and background that the Director brings to the Board relative to its needs and existing composition; the results of the most recent Board self-evaluation; and any shareholder feedback.

CORPORATE GOVERNANCE MATTERS 2026 PROXY STATEMENT 19

Consideration of Director Candidates from Shareholders The Corporate Governance Committee will consider Director candidates recommended by shareholders. As with any potential nominee, the Corporate Governance Committee will evaluate shareholder-nominated candidates in light of the needs of the Board and the qualifications of the particular individuals. In addition, the Corporate Governance Committee may consider the number of shares held by the recommending shareholder and the length of time such shares have been held. To recommend a candidate for the Board, a shareholder must submit the recommendation in writing, including: (i) the name of the shareholder and evidence of the person’s ownership of common stock of the Company (“Common Stock”), including the number of shares owned and the length of time of ownership; (ii) the name of the candidate, the candidate’s principal occupation or employment or qualifications to be a Director; (iii) the candidate’s consent to be named as a Director if nominated by the Board, and (iv) other requirements specified in our Bylaws. The shareholder recommendation and information described above generally must be received by the Corporate Secretary not less than 90 nor more than 120 days prior to the anniversary date of the immediately preceding annual meeting of shareholders. However, if the annual meeting is called for a date that is not within 25 days before or after such anniversary date, notice by the shareholder, to be timely, must be received no later than the close of business on the 10th day following the day on which notice of the date of the annual meeting was mailed or public disclosure of that date was made, whichever occurs first. In the case of a special meeting of shareholders called for the purpose of electing directors, the recommendation and accompanying information must be received by the Corporate Secretary not later than the close of business on the 10th day following the day on which notice of the special meeting was mailed or public disclosure of the date of the special meeting was made, whichever first occurs. Shareholder recommendations and accompanying information should be sent to the Corporate Secretary at Aflac Incorporated as described at the end of this Proxy Statement under the heading “Other Proposals or Director Nominations to be Brought Before our 2027 Annual Meeting.” Our proxy access bylaw permits a shareholder (or group of up to twenty shareholders) owning shares of our outstanding Common Stock representing at least 3% of the votes entitled to be cast on the election of Directors to nominate and include in our proxy materials Director candidates constituting up to 20% of the Board. The nominating shareholder or group of shareholders must have owned their shares continuously for at least three years, and the nominating shareholder(s) and nominee(s) must satisfy other requirements specified in our Bylaws.						Board Self-Evaluation The effectiveness of our Board is of the utmost importance. The Board recognizes that we live in a dynamic world that requires regular self-evaluation to help ensure that we have the best skill set and experience to serve the Company and that the Board is fulfilling its responsibilities. 1    ANNUAL ASSESSMENT OVERSIGHT The Corporate Governance Committee is charged with overseeing an annual process of self-evaluation for the Board as a whole and for its individual members.
						2    COMMITTEE SELF-EVALUATIONS The charters of each Board committee also require annual evaluations of the performance of the committee, which are typically overseen by each committee’s chair.
						3    ONE-ON-ONE DISCUSSIONS The annual process, which includes completion of written questionnaires for the Board and for each committee on which the Director serves, involves an interview of each Director.
						4    EXECUTIVE SESSIONS The Chairman discusses the results of the surveys and interviews with the full Board in executive sessions. In addition, the Lead Non-Management Director leads executive sessions with the Board, without the Chairman, to discuss the self-evaluation results.
						5    FEEDBACK INCORPORATED Based on the self-evaluation results, any follow-ups including changes in practices or procedures are considered and implemented, as appropriate.
						TOPICS DISCUSSED
						•Board structure and composition •Effectiveness of oversight and other responsibilities •Access to management, information, and other resources			•Meetings and materials •Quality of director participation •Fulfillment of charter responsibilities •Refreshment and succession
						In addition to the formal self-evaluation process, the Non-employee Directors regularly meet in executive session, during which the Board’s performance and oversight responsibilities are frequently discussed.

Our Board and Committees

Board Leadership Structure

The Board is charged with managing the business and affairs of the Company and retains discretion to determine the leadership structure that it believes best serves the Company and its shareholders in light of its fiduciary duties and the Company’s circumstances at any given time. In exercising this judgment, the Board recognizes that leadership structure is not a one-size-fits-all determination, but rather should reflect the Company’s strategy, regulatory environment, and operational complexity. As such, the Board does not have a policy on whether or not the role of the Chairman and Chief Executive Officer should be separate, or, if the roles are to be separate, whether the Chairman should be selected from the non-employee Directors.

Consistent with its authority, the Board evaluates its leadership structure at least annually as part of its governance review process and may determine to combine or separate the roles of Chairman and Chief Executive Officer as circumstances warrant. If the Chairman and Chief Executive Officer roles are filled by the same person, or if the Chairman is not independent, the Board believes that an independent Director should be appointed to serve as the Lead Non-Management Director. Based upon a recommendation by the Corporate Governance Committee, the Lead Non-Management Director is elected annually by the Board (effective at the first Board of Directors meeting following the Annual Meeting of Shareholders). Although subject to an annual election, the Lead Non-Management Director is generally expected to serve for more than one year.

The role of Chairman and Chief Executive Officer has been held by Mr. Amos for nearly 25 years, providing stability and leadership informed by extensive experience and deep knowledge of the Company’s business and industry. The role of Lead Non-Management Director has been held by W. Paul Bowers since 2019, providing strong independent oversight informed by clearly-defined and substantial responsibilities. Given the Company’s significant presence in Japan and the United States, long-term capital management focus, and highly regulated business model, at this time, the Board believes that unified leadership supports effective alignment between strategic oversight and operational execution and robust and independent oversight is provided through the Lead Non-Management Director role and its independent committees.

The Board believes its existing corporate governance practices facilitate independent oversight and management accountability. These governance practices are reflected in the Company’s Guidelines on Significant Corporate Governance Issues, Committee charters, and through our long-standing practices. In particular:

•a substantial majority of our Board members are independent;

•the Audit and Risk, Compensation, and Corporate Governance Committees all comprise independent Directors;

•the Company has a Lead Non-Management Director with significant responsibilities, as described below;

•the Non-employee Directors meet at each regularly scheduled Board meeting in executive session without management present;

•the Corporate Governance Committee oversees and manages the annual assessment of Board performance, which includes consideration of the effectiveness of our Board leadership structure;

•our shareholders have several avenues to make their views known, including the ability to amend the Bylaws of the Company, to call a special meeting of shareholders and to include director nominations in our proxy materials; and

•members of our management team and/or independent Directors proactively engage on a year-round basis with our shareholders to understand their perspectives on our business, strategy, management, Board, and governance practices.

			Daniel P. Amos CHAIRMAN AND CEO Mr. Amos has served as Chairman of the Board since 2001 and as CEO since 1990. The Board believes the most effective Board leadership structure for the Company at this time is for the CEO to continue to serve as Chairman, working with a Lead Non-Management Director. This structure has served the Company well for many years. The CEO is ultimately responsible for the day-to-day operation of the Company and for executing the Company’s strategy, and the Company’s performance is an integral part of Board deliberations. Accordingly, the Board believes that Mr. Amos is the Director most qualified to act as Chairman. Mr. Amos’ detailed institutional knowledge of the Company’s operations and his vision for the Company’s development provides decisive and effective leadership for the Board, enables efficient and effective decision-making with focused accountability and helps to ensure that the Company presents its message and strategy to shareholders, employees, policyholders, and other stakeholders through one unified voice. However, the Board retains the authority to modify this structure to best advance the interests of all shareholders if circumstances warrant such a change.
			W. Paul Bowers LEAD NON-MANAGEMENT DIRECTOR The Corporate Governance Committee has nominated Mr. Bowers to serve as Lead Non-Management Director, a position he has held since May 2019. Mr. Bowers’ experience at Southern Company, particularly his strong leadership and operational background, make him well-suited to serve as our Lead Non-Management Director. He has also served as Chair of our Corporate Development Committee and is currently a member of our Audit and Risk, Corporate Social Responsibility and Sustainability, and Executive Committees.

CORPORATE GOVERNANCE MATTERS 2026 PROXY STATEMENT 21

Responsibilities of the Lead Non-Management Director

Since 2003, the Board has annually elected an independent director as the Lead Non-Management Director. The Lead Non-Management Director role is modeled on the role of an independent board chair, which helps to ensure a strong, independent, and active board. Our Guidelines on Significant Corporate Governance Issues include the following responsibilities of the Lead Non-Management Director:

•consulting with the Chairman and Corporate Secretary to establish the agenda for each Board meeting;

•setting the agenda for, and leading, all executive sessions of the Non-employee Directors;

•when appropriate, discussing with the Chairman matters addressed at such executive sessions;

•presiding over meetings of the Board at which the Chairman is not present;

•presiding over discussions of the Board when the topic presents a potential conflict of interest for the Chairman;

•facilitating discussions among the Non-employee Directors between Board meetings;

•serving as a liaison between the Non-employee Directors and the Chairman;

•when appropriate, serving as a liaison between management and the Board;

•representing the Board in shareholder outreach; and

•facilitating the annual Board self-evaluation in coordination with the Chairman.

The Lead Non-Management Director has the authority to call meetings of the independent Directors.

Committee Structure

The Board has seven standing committees: Audit and Risk; Compensation; Corporate Development; Corporate Governance; Corporate Social Responsibility and Sustainability; Executive; and Finance and Investment. Each committee (other than the Executive Committee) operates under a written charter adopted by the Board. Charters for the Audit and Risk Committee, the Compensation Committee, and the Corporate Governance Committee all can be found on the Company’s website, aflac.com, under “Investors,” then “Governance,” and then “Governance Documents.”

All members of the Audit and Risk, Compensation and Corporate Governance Committees qualify as “outside” Directors as defined by Section 162(m) of the Internal Revenue Code, “Non-employee Directors” within the meaning of Rule 16b-3 of the Securities Exchange Act of 1934, as amended, (the “Exchange Act”) and independent Directors under NYSE listing standards, as appropriate.

Board Committee Refreshment

The Corporate Governance Committee considers the periodic rotation of committee members and committee chairs to introduce fresh perspectives and to broaden and diversify the views and experience represented on Board committees. Beginning May 4, 2026, the Corporate Governance Committee has nominated Mr. Michael A Forrester to succeed Mr. W. Paul Bowers as a member of the Corporate Social Responsibility and Sustainability Committee.

Meeting Attendance

The Board met four times in 2025, and all Directors attended at least 75% of the meetings of the Board and the committees on which they served as a member for the period for which they served. It is Company policy that each Director should attend the Annual Meeting. All Directors serving at the time attended the 2025 Annual Meeting, which was held virtually.

Director Onboarding and Continuing Education

In accordance with our Guidelines on Significant Corporate Governance Issues, the Company provides new Directors with a director orientation program to familiarize such Directors with, among other things, the Company’s business, strategic plans, significant financial, accounting and risk management issues, compliance programs, conflicts policies, Code of Business Conduct and Ethics, corporate governance policies, principal officers, internal auditors and independent auditors. Each Director is expected to participate in continuing education programs in order to maintain the necessary level of expertise to perform his or her responsibilities as a Director. Subject matter experts are frequently invited to meetings to present on emerging matters or to provide deeper dives into topics of interest. In addition, it is highly recommended that each Director attend (either in person or via webcast) the Company’s presentations to financial analysts and listen to the Company’s quarterly conference calls with financial analysts. This policy helps ensure that Directors are sufficiently informed of the material aspects of the Company’s public disclosures, financial condition and business operations.

CORPORATE GOVERNANCE MATTERS 2026 PROXY STATEMENT 27

Board Responsibilities

Oversight of Risk

Board of Directors

Our Board oversees our enterprise-wide risk management system, which is designed to achieve organizational and strategic objectives, improve long-term performance, and enhance shareholder value. The Board must understand the risks the Company faces and the steps management takes to manage those risks as well as what level of risk is appropriate for the Company. Our Directors are equipped to make all of these determinations because they are integral to the process of setting the Company’s business strategy.

The Board oversees the risk-management process in conjunction with Board and management committees, each with varying aspects of enterprise risk management as part of their responsibilities. Examples of Board committee risk management oversight are noted below.

AUDIT AND RISK COMMITTEE Oversees the Company’s policies, process, and structure related to enterprise risk management and compliance including:
•discusses guidelines and policies governing the process by which senior management and the relevant departments of the Company assess and manage exposure to risk, as well as the Company’s major financial risk exposures and the steps management has taken to monitor and control such exposures; •reviews the Company’s risk assessment and enterprise risk-management framework, including risk-management guidelines, risk appetite, risk tolerances, key risk policies, and control procedures;  •reviews critical regulatory risk-management filings and enterprise risk-management material shared with regulators and rating agencies;			•reviews the general structure, staffing models, and engagement of the Company’s risk governance departments and practices;  •reviews the Company’s major financial risk exposures and evaluates processes and controls that management has adopted to monitor and manage those risks; •meets in executive session with key senior leaders involved in risk management;			•reviews with the internal auditors, the independent auditor, and the Company’s financial management team the adequacy and effectiveness of our internal controls, including information security policies and internal controls regarding information security, and any special steps adopted in light of material control deficiencies; and •reports to the Board, at least annually, with respect to matters related to key enterprise risks and risk management areas of concentration.
FINANCE AND INVESTMENT COMMITTEE Oversees the investment process and investment risk management of the Company and its subsidiaries by monitoring investment policies, strategies, and transactions and reviewing the performance of the investment portfolio and overall capital and liquidity position of the Company:
•Investment risk: Includes liquidity risk, market risk, and credit risk. •Liquidity risk: When an investment is not marketable and cannot be bought or sold quickly enough to prevent or minimize a loss.			•Market risk: The risk that market movements will cause fluctuations in the value of our assets, the amount of our liabilities, or the income from our assets. •Credit risk: The risk of loss arising from the failure of a counterparty to perform its contractual obligations.			•Enterprise Capital & Liquidity risk: Review of enterprise capital adequacy, access to capital, and maintenance of liquidity position to protect credit ratings and the Company’s ability to meet short and long-term obligations.
COMPENSATION COMMITTEE Oversees the Company’s compensation plans and practices and strives to create incentives that encourage a level of risk-taking behavior consistent with the Company’s business strategy:
•reviewing the Company’s incentive compensation arrangements to determine whether they encourage unnecessary or excessive risk-taking;			•reviewing at least annually the relationship between the Company’s compensation and risk management policies and practices;			•evaluating compensation policies and practices that could mitigate any such risk.
As more fully discussed in the Compensation Discussion and Analysis section of this Proxy Statement, the Compensation Committee establishes incentive compensation performance objectives for management that are directly linked to the Company’s results, aligned with shareholder interests, and realistically attainable so as not to encourage excessive risk taking.

Role of Management

The Company’s management is responsible for day-to-day risk management. Our enterprise risk-management framework, which is aligned with and overseen by the Board and its committees, includes several executive management committees whose roles incorporate risk management across the enterprise. For example, executive management’s Global Risk Committee oversees the processes for identifying, assessing, measuring, monitoring, and mitigating key risks in addition to ensuring transparency and appropriateness of reporting to executive leadership. Other management committees, and specific management positions such as the Company’s Global Chief Risk Officer, its General Counsel, and its Global Chief Compliance Officer, are responsible for implementing policies and risk-management processes relating to strategic, operational, investment, competitive, regulatory and legislative, product, reputational, and compliance risks.

Spotlight on Information Security Risk Oversight

The Board has adopted an information security policy directing management to establish and operate a global information security program with the goals of identifying, assessing and monitoring existing and emerging cybersecurity threats and helping ensure that the Company’s information assets and data, and the data of its customers, are appropriately protected from loss or theft. The Board has delegated oversight of the Company’s information security program to the Audit and Risk Committee. The Company’s senior officers, including its Global Chief Information Security Officer (GCISO), are responsible for the operation of the global information security program and communicate with the Audit and Risk Committee quarterly and the full Board three times a year on the program, including with respect to the state of the program, compliance with applicable regulations, current and evolving threats, and recommendations for changes in the global information security program. The global information security program also includes a cybersecurity incident response plan that is designed to provide a management framework across Company functions for a coordinated assessment and response to cybersecurity incidents. This framework establishes a protocol to report certain incidents to the GCISO and other senior officers, with the goal of timely assessing such incidents, determining applicable disclosure requirements, and communicating with the Audit and Risk Committee as appropriate. The incident response plan directs the executive officers to report certain incidents immediately and directly to the Lead Non-Management Director and/or the Chair of the Audit and Risk Committee.

For more information, see the Aflac Incorporated Cybersecurity Disclosure at investors.aflac.com under the “Sustainability” tab, then “Policies and Statements.” See also Item 1C of the Company’s Annual Report on Form 10-K for the year ended December 31, 2025.

Oversight of Strategy

The Board oversees and monitors strategic planning. Business strategy is a key focus at the Board level and embedded in the work of Board committees.

Chief Executive Officer and Executive Management Succession Planning

The Board, in coordination with the Corporate Governance Committee, is responsible for succession planning for key executives to help ensure continuity in senior management. As part of that effort, the Board and the Corporate Governance Committee ensure that the Company has an appropriate process for addressing Chief Executive Officer succession as a matter of regular planning and in the event of extraordinary circumstances.

The Chief Executive Officer plays an active role in the succession-planning process for other executive management positions. In coordination with the Company’s executive management team, including the General Counsel and the Chief Human Resources Officer, the Chief Executive Officer periodically evaluates potential successors, reviews development plans recommended for such individuals, and makes recommendations to the Corporate Governance Committee. Together these parties also identify potential successors for other critical executive management positions. In addition, the Chief Executive Officer reviews executive succession planning and management development at an annual executive session of independent Directors.

Shareholder Engagement

The Company has a long history of engaging shareholders to provide updates on key governance, Board, compensation and sustainability topics, to learn about the issues that are important to them and address any concerns that they may have. We believe that open communications can have a positive influence on our performance as we seek to continually improve our practices and enhance our disclosure. For example, we are proud to have been the first publicly traded company in the United States to voluntarily allow shareholders a Say-on-Pay vote. In keeping with this governance philosophy, we communicate with our shareholders on a regular basis and incorporate their feedback into our decision-making process.

Director Compensation

Directors who also serve as employees of the Company or its subsidiaries do not receive compensation as Board members. The Compensation Committee reviews our policy regarding total compensation for Non-employee Directors at least every other year and recommends compensation to the Board consistent with that policy. When making its recommendation, the Compensation Committee considers a variety of factors, including the Non-employee Director pay packages at our peer group companies, the skills and backgrounds required of Non-employee Directors to serve on the Company’s Board, and the balance between the cash and equity components of the package. The Board makes final determinations regarding Non-employee Director compensation.

The Compensation Committee assesses Director compensation and uses its independent compensation consultant to benchmark against the peer group at least every other year.

Cash Compensation

For 2025, cash compensation for the Non-employee Directors was as follows:

All Non-employee Directors (annual cash retainer)			$135,000 annually
All Audit and Risk Committee members			Additional $15,000 annually
Chairs—Compensation, Corporate Governance, Corporate Social Responsibility and Sustainability, Corporate Development, Finance and Investment			Additional $25,000 annually
Chair—Audit and Risk			Additional $35,000 annually
Lead Non-Management Director(1)			Additional $50,000 annually

(1)The aggregate dollar value will be increased to $60,000 in 2026 to align cash compensation with the peer group median as determined by the Compensation Committee’s independent compensation consultant.

Non-employee Directors may elect to have all or a portion of their Board annual cash retainer and other cash compensation paid in the form of immediately vested nonqualified stock options, restricted stock that vests after one year of continued service, or a combination thereof as determined by the Board. In 2025, one Non-employee Director elected to receive restricted stock in lieu of an annual cash retainer and other cash compensation.

Equity Compensation

As shown below, Non-employee Directors also receive equity on a regular basis to further align their interests with those of our shareholders.

Timing of equity grant			Form of equity grant(1)			Value of equity grant(2)
Upon joining the Board			nonqualified stock options, restricted stock, stock appreciation rights, or a combination thereof			aggregate value as determined by the Board not in excess of the value of a nonqualified stock option covering 20,000 shares of Common Stock
Annually, at the discretion of the Board			restricted stock, nonqualified stock options, stock appreciation rights, or a combination thereof			aggregate dollar value of approximately $180,000(3)

(1)If the Board determines that restricted stock grants will be made, it may permit Non-employee Directors to elect to receive nonqualified stock options in lieu thereof. In 2025, the Board made grants of restricted stock, and none of the Non-employee Directors made the election.

(2)The values of any nonqualified stock options or stock appreciation rights are determined based upon the most current Black-Scholes-Merton three-year period valuation price of option shares as determined by the Compensation Committee’s independent compensation consultant. For grants made in the three-year period of 2025 to 2027, our deemed fair value of a stock option is $24.64.

(3)The aggregate dollar value will be increased to $195,000 in 2026 to align the grant with the peer group median as determined by the Compensation Committee’s independent compensation consultant.

CORPORATE GOVERNANCE MATTERS 2026 PROXY STATEMENT 33

The Company believes its Non-employee Directors should have a significant equity interest in the Company and has enforced stock ownership guidelines for the Non-employee Directors since 1998. A summary of the requirements is shown below.

Position			Ownership Guideline			What Counts			What Does Not Count
Non-employee Directors			5x annual cash retainer			Ownership includes all shares beneficially owned by the Non-employee Director, as well as time-based, unvested restricted shares.			Stock options (vested or unvested) do not count toward these stock ownership guidelines.

Each Non-employee Director has stock ownership that exceeds the ownership guidelines or is working toward meeting the requisite guideline within the allowed time frame. For additional information, please see “Additional Executive Compensation Plan Practice and Procedures” on page 56.

Vesting

Grants of stock options or, if elected, restricted stock, made to Non-employee Directors upon joining the Board become vested one year from the grant date, generally subject to continued service. Grants of restricted stock or, if elected, stock options, made to Non-employee Directors at the time of an annual meeting become vested at the next annual meeting, generally subject to continued service. Notwithstanding the foregoing, as noted under the “Cash Compensation” section above, stock options granted to Non-employee Directors at their election in lieu of their annual cash retainer and other cash compensation are fully vested upon grant. Upon death or disability or a change in control of the Company, Non-employee Directors will become 100% vested in all outstanding options and stock awards.

EXECUTIVE COMPENSATION

 

Named Executive Officer Compensation
(“Say-on-Pay”)

We are committed to achieving a high level of total return for our shareholders. From the end of August 1990, when Daniel P. Amos was appointed the CEO, through December 31, 2025, the Company’s total return to shareholders, including reinvested cash dividends, has exceeded 21,594%, compared with 4,123% for the Dow Jones Industrial Average, 4,223% for the S&P 500 Index, and 1,916% for the S&P 500 Life & Health Insurance Index over the same period.

 The Board of Directors recommends a vote FOR our executive  compensation program.

We believe our compensation policies and procedures are strongly aligned with the long-term interests of our shareholders and exemplify our pay-for-performance culture . Beginning in 2008, we voluntarily provided our shareholders an annual advisory vote (commonly known as “Say-on-Pay”), which is now required by the Dodd-Frank Wall Street Reform and Consumer Protection Act. In accordance with Section 14A of the Exchange Act, this vote gives you as a shareholder the opportunity to endorse or not endorse the compensation of our named executive officers through the following resolution:

“Resolved, on an advisory basis, the shareholders of Aflac Incorporated approve the compensation of the named executive officers, as disclosed pursuant to the compensation disclosure rules of the Securities and Exchange Commission, including the Compensation Discussion and Analysis and accompanying tables and narrative in the Notice of 2026 Annual Meeting of Shareholders and Proxy Statement.”

Because your vote is advisory, it will not be binding upon the Board. However, the Compensation Committee will take the outcome of the vote into account when considering future executive compensation arrangements.

Pay-For-Performance Compensation Philosophy

Our compensation programs are designed to ensure that a substantial amount of executive pay is directly linked to the Company’s results. We believe this is an appropriate and effective method for creating alignment with shareholder interests and that it has played a significant role in making the Company an industry leader. Importantly, performance-based elements of our compensation programs apply to all levels of Company management—not just the executive officers. In fact, pay-for-performance components permeate compensation at nearly every employee level. As a result, we are able to attract, retain, motivate, and reward talented individuals who have the necessary skills to manage our growing global business on a day-to-day basis and to position the Company for success in the future.

The Compensation Committee’s independent compensation consultant, Mercer (US) LLC, works with the Compensation Committee to review executive compensation practices, including the competitiveness of pay levels, design issues, market trends, and other technical considerations.

Our executive compensation program is designed to drive shareholder value via three compensation philosophy pillars:

1						2						3
			A pay-for-performance philosophy and compensation program structure that directly motivates our executives to achieve our annual and long-term strategic and operational goals						Compensation elements that help us attract and retain high-caliber talent to lead the Company						“Best practice” compensation governance policies, such as stock ownership guidelines, clawback policy, and no change-in-control excise tax gross-ups

2025 Operating Results

In 2025, the Company continued to build upon our market-leading position in supplemental health insurance to drive long-term shareholder value.

Aflac Incorporated

For 2025, the Company reported net earnings per diluted share of $6.82 and adjusted earnings per diluted share of $7.49, or $7.46 excluding the effect of foreign currency, which was the Company's best year in its history. Earnings benefited primarily from the favorable underwriting experience in Japan relative to our expectations, which resulted in significant remeasurement gains in the third quarter of the year. The earnings also benefited from disciplined expense management in both Japan and the U.S.

For the year, the Company generated a strong return on equity of 13.1% and our AROE, excluding the impact of foreign currency, for the full year was 17.5%. The adjusted leverage ratio(1) of 21.4% fell within a conservative range of 20% to 25%.

Management and the Board are committed to ensuring comprehensive risk management and to safeguarding the Company’s financial strength. Aflac Japan ended the year with an SMR of 995%, and Aflac U.S. had a combined RBC ratio of 570%. The Company’s strong capital and cash flow continue to support our financial strength ratings, which are among the highest in the industry,$3.5 billion in share repurchase in 2025, and our 43-year track record of increased Common Stock dividends.

Summary of Our Executive Compensation Program

As a leader in our industry segment, we recognize that a sound executive compensation program is one element of why we are an employer of choice and why our shareholders have consistently supported our executive compensation program through our annual Say-on-Pay vote. Our executive compensation program directly links compensation incentives with our business goals and shareholder interests.

We consider annual incentive and long-term incentive compensation to be the most important compensation awarded because these pay elements represent the largest part of total rewards for executives and provide the strongest link to Company results and shareholder value creation. Moreover, incentive compensation enables us to attract, retain, motivate, and reward talented individuals who have the necessary skills to manage our growing global enterprise now and for the future. Due to our focus on incentive compensation, base salary is the smallest component of compensation for the NEOs.

Outcome of 2025 Say-on-Pay Vote

The Company has a history and a well-earned reputation with its shareholders as a transparent organization. That commitment to transparency on all levels was a driving force behind our decision in 2008 to allow shareholders a “Say-on-Pay” advisory vote, years before such votes became mandatory for most public companies. In 2025, over 96% of our shareholders voted in favor of our NEO executive compensation program. Consistent with our approach in prior years, the Company engaged in shareholder outreach efforts throughout 2025. The feedback from these conversations, together with a thorough analysis of best practices and guidance from our independent compensation consultant, was incorporated into the Compensation Committee’s regular review of our compensation programs. Compensation program changes, if any, are made with a focus on ensuring that pay is linked to Company performance and corporate strategy. We continually analyze our compensation program to ensure that we remain current in our approaches, a leader in executive compensation best practices, and cognizant of shareholder viewpoints. Moreover, we pride ourselves on incorporating ethics and transparency into everything we do, including compensation design and disclosure. Accordingly, we will continue our review and dialogue with investors to determine if additional changes are warranted. After careful consideration, the Compensation Committee did not make any changes to our executive compensation program and policies for 2025. 2025 SAY-ON-PAY SUPPORT 96.6%

Independent Compensation Consultant

The Compensation Committee is directly responsible for the appointment, compensation and oversight of the work of any compensation consultant or other adviser retained by the Compensation Committee. The Compensation Committee has retained a nationally recognized compensation consultant, Mercer (US) LLC (“Mercer”), to assist and advise the Compensation Committee in designing and refining the Company’s executive compensation program. Fees paid to Mercer for these services totaled $337,428 in 2025. Management retained certain Mercer affiliates to provide additional services not pertaining to executive compensation during 2025, and approved payments for those services totaling $532,021. Those additional services included developing a strategic approach to create a more diverse sales channel network across the U.S. to support increased opportunities for revenue growth. In addition, as the Company grows the sales of its insurance products through brokers in the U.S., this has resulted in commission payments totaling $23,398,828 during 2025 to the broker subsidiaries of Mercer. These subsidiaries are separate from the subsidiary that provides compensation consulting to the Company. As reported by Mercer to the Compensation Committee, the total payments from the Company represented 0.10% of Mercer’s parent company’s annual revenue. The Compensation Committee assessed Mercer’s independence pursuant to SEC rules and NYSE listing standards and concluded that no conflict of interest exists with respect to the work Mercer performs for the Compensation Committee.

Importance of the Peer Group

The Compensation Committee sets target compensation for the NEOs at market competitive levels with the assistance of its independent compensation consultant. Factors considered include target pay levels in the market for comparable roles, the primary duties and responsibilities of the role at the Company, and the individual’s relevant experience and performance.

As discussed in this CD&A, the Compensation Committee considers our peer group when setting compensation amounts and targets. Each year, the Compensation Committee, with the assistance of its independent compensation consultant, reviews the composition of the peer group to assess its continued appropriateness. Key factors the Compensation Committee considers during this annual review include operating characteristics, revenue size, asset size, profitability, market value, and total number of employees. Based on the annual review, the Compensation Committee selects a peer group of companies that are engaged in businesses similar to that of the Company, are of a similar size as the Company, and compete against the Company for talent. Overall, in terms of the size factors considered, the Company is positioned near the middle of this group.

Performance-Based Compensation: How Performance Goals Are Set The Board and the Compensation Committee believe it is important for the Company to manage its business to provide long-term value to our shareholders. Therefore, performance goals under the MIP and LTI programs involve metrics that support shareholder returns, and payouts depend entirely upon the level of achievement of those goals. The following sections provide detail on how we select metrics under the MIP and LTI program, determine performance target amounts and other important considerations in setting these targets. While performance goals are continually evaluated and refreshed as appropriate, we have used the same methodology for setting MIP and LTI goals for many years. Segment metrics for Aflac U.S., Aflac Japan, and Global Investments are consistent with assumptions used in developing segment financial projections (described below) based on the Company’s best estimates for the coming year. The segment projections are consolidated into the corporate financial projection used to develop performance targets.						The goal-setting process generally proceeds in two stages: 1  RECOMMEND •The Company’s CEO and CFO, in consultation with Mercer, recommend to the Compensation Committee specific Company performance objectives that are aligned with corporate strategy and thus are designed to drive shareholder value and ensure financial soundness. •Recommended ranges are based, in part, on past performance results and scenario tests of the Company’s financial outlook as projected by a complex financial model. •The model projects the impact on various financial measures using different levels of total new annualized premium sales, investment returns, budgeted expenses, morbidity, persistency, return on equity, and capital ratios.
						2  ESTABLISH •The Compensation Committee refers to these modeled results to establish a target performance level, as well as a minimum and maximum level, for each performance goal. •The target goal is not necessarily equidistant between the minimum and maximum goals. Instead, for certain key metrics the MIP payout curve is “sloped” to require significant above-target performance to achieve a maximum payout. •Correspondingly, the payout for a minimum result is one-half of the target payout, while the payout for the maximum goal (or better) is twice the target payout. •No payouts are made for performance below the minimum goal. •Interpolation is used to calculate incentive payouts for results between minimum and target goals or target and maximum goals. •The 2025 MIP goals were approved by the Compensation Committee in March 2025.

For 2025, the Compensation Committee established the following metrics under the MIP:

•Corporate Metric: Adjusted earnings per diluted share excluding foreign currency effect

•U.S. Segment: New Annualized Premium Sales and Net Earned Premium

•Japan Segment: New Annualized Premium Sales and Net Earned Premium

•Global Investment Metrics: Net Investment Income (U.S. and Japan GAAP Segments only) and Credit Losses/Impairments

Considerations in setting the target goal amount for each of these MIP metrics are described in more detail below.

Importance of Measuring Management’s Performance Excluding the Impact of Currency

Since 1991, the Company has communicated external earnings results that exclude foreign currency effects. Similarly, objectives are set on a currency-neutral basis.

Aflac Japan’s performance is important to our results, as the Japan segment accounted for approximately 53% of total adjusted revenues for the year ending December 31, 2025. The Company’s reported U.S. GAAP revenue, earnings, assets, book value, and cash flow are affected by changes in the relative values of the yen and the dollar, which changes are outside management’s control. When setting the objectives, the Compensation Committee strongly believes that management should not be unduly rewarded because of short-term movement in the yen/dollar exchange rate when the yen is strong or penalized in periods of yen weakening when those currency shifts influence key incentive compensation metrics.

EXECUTIVE COMPENSATION 2026 PROXY STATEMENT 45

MIP Target-Setting

In addition to currency neutrality, the Compensation Committee considers the prior year’s results, current business operating environment and the forecasts emerging from the Company’s strategic planning process when setting objectives for each MIP metric. For 2025, the majority of the MIP performance metrics were structurally consistent with the 2024 performance objectives, including weightings with specific “sloping” targets, with ranges adjusted for the 2025 financial plan. The Company utilizes an outlook of adjusted earnings per share in setting MIP goals. The goals for these metrics are generally consistent with the Company’s public disclosure during the Financial Analysts Briefing on December 3, 2024, and the subsequent fourth quarter 2024 earnings release and conference call.

Metric			Performance Measures			Factors Considered in Setting Goal Levels
Corporate Metric			•Adjusted EPS			In 2024, the Company generated $5.4 billion in net earnings, up 16.8% for the year, or $9.63 per diluted share. The Company also reported a 9.1% increase in adjusted earnings for the year, which were $4.1 billion, and adjusted earnings per diluted share of $7.21, which was up 15.7%. This increase was supported by the repurchasing of $2.8 billion (30.4 million) of the Company’s shares and higher adjusted earnings. Higher adjusted earnings were primarily driven by higher net investment income and a lower benefit and expense ratio in the U.S. For 2025, the Company’s currency-neutral adjusted EPS was expected to be lower than the previous year primarily due to lower adjusted earnings which included headwinds to both total adjusted revenues and other adjusted expenses resulting from lower net investment income in both Japan and U.S., lower earned premium in the Japan segment mainly from paid-up impact, and higher benefit ratios primarily due to favorable third quarter unlocking impacting to prior year comparison and higher 2025 U.S. Segment benefit ratio estimates driven by continued initiatives to provide better value for the customer. Consistent with prior years, we continue to slope the ranges for adjusted EPS to require higher performance for maximum payout.
U.S. and Japan Segment Metrics			•New Annualized Premium Sales •Net Earned Premium			In 2024, Aflac U.S. new annualized premium sales decreased 1.0%. The decrease in new annualized premium sales for Aflac U.S. in 2024 primarily reflected lower sales of group voluntary benefit products impacted by a continued focus on profitable growth, as well as softer sales of network dental. Net earned premiums increased 2.7% in 2024 primarily due to higher net earned premiums from growth initiatives including group life and disability and consumer markets businesses. Moving into 2025, our business focus continued to be building out our growth properties, while continuing to strengthen our distribution reach for our core voluntary products. The Company expected sales growth in 2025 and the Compensation Committee set a range of 0% to 14% increase in sales for the year. After considering current economic volatility and our expected sales growth, the Company expected net earned premium growth in the 1.3% to 5.3% range. Similarly, in Japan, the focus was on post-pandemic recovery and realization of investment in product development. In 2024, Aflac Japan new annualized premium sales increased 5.6% to ¥64.1 billion, which was largely driven by an increase in Tsumitasu. This contributed to strengthening our customer base, which is crucial for our future growth. Moving into 2025 the Compensation Committee decided to shift the range of sales upwards for the year because the third sector sales are expected to continue to grow due to a very extensive product line up with Tsumitasu and Miraito and our focus on hiring activities of the mainstay associates and expanding the number of sales agents. Additionally, net earned premium was expected to decline largely due to limited pay third sector policies becoming paid-up and the impacts of reinsurance. The Compensation Committee set a range of approximately ¥63.0 billion to ¥72.2 billion for sales including Japan Post and set a range of -5.55% to -4.00% for net earned premium.

46 AFLAC INCORPORATED EXECUTIVE COMPENSATION

Metric			Performance Measures			Factors Considered in Setting Goal Levels
Global Investment Metrics			•Net Investment Income •Credit Losses/ Impairments			For 2025, Aflac Japan net investment income including hedge costs was expected to be lower than the prior year, primarily driven by the lower assets from the additional reinsurance transaction with Aflac Re in 2024. Expected lower yields were largely offset by interest rate hedges. The Company expected net investment income for Aflac U.S. to decrease in 2025, reflecting lower yields and lower deployable cash because of higher contributions to Aflac Incorporated. Our planning assumed a positive 10% return for variable net investment income for both Aflac Japan and Aflac U.S. Target levels for credit losses and impairments are determined with consideration of current asset quality, current and expected market conditions, and potential trading activity to improve the overall health of the portfolio. In order to properly balance income and risk, targets for 2025 were expressed as a range around budget based on a bottom-up review of asset allocation and cash flows. As in 2024, we continued to slope the ranges for Net Investment Income to require above budget targeted performance for maximum payout, while not encouraging excessive risk-taking.

Equity Granting Policies

The following is a discussion of the Company’s equity award grant practices in relation to the disclosure of material nonpublic information, as required by Item 402(x) of Regulation S-K. Equity awards are discretionary and are generally granted at the discretion of the Compensation Committee. The Company does not currently (and during 2025 did not) grant stock options to its employees. The Compensation Committee did not take material nonpublic information into account when determining the timing and terms of equity awards in 2025, and the Company does not time the disclosure of material nonpublic information for the purpose of affecting the value of executive compensation. Eligible employees, including our NEOs, also have the opportunity to participate in the AFL Stock Plan through monthly payroll deductions. The Company may periodically make additional equity grants during the course of the year, but as a matter of policy does not make equity grants in advance of material news releases. Each year, typically in February, the Compensation Committee meets shortly after the Company’s fiscal year results are released to the public. At that time, the Compensation Committee reviews recommendations developed by the CEO and CFO (with input from Mercer as the Compensation Committee’s independent consultant) for setting amounts and metrics with respect to LTI awards of PBRS and time-based restricted stock. For PBRS, the specific Company performance objectives are aligned with long-term corporate strategy, and thus are intended to drive shareholder value and ensure financial soundness.

2025 Executive Compensation

Elements of Our Executive Compensation Program

Base Salary

The base salaries of our named executive officers are competitively positioned relative to comparable executives in our peer group and in the broader insurance sector, generally targeting market median, but also reflect each individual’s scope of responsibilities and performance. The Compensation Committee uses comparative market data for salaries in reviewing and determining the CEO’s salary, and the CEO uses the market data to inform his recommendations to the Compensation Committee regarding the salaries of the other executive officers.

Mr. Amos has not received a salary increase in the last thirteen years. Mr. Brodén, Mr. Miller and Mrs. Tillman received base salary increases effective January 1, 2025 of 8.8%, 17.9%, and 10.0%, respectively, to align their respective base salary competitively relative to similar roles in the market. Mr. Dyslin received base salary increases of 4% and 10% effective January 1, 2025, and July 1, 2025, respectively, to align his respective base salary competitively relative to similar roles in the market.

Management Incentive Plan

All NEOs are eligible to participate in the Management Incentive Plan (MIP), an annual non-equity incentive plan, which was approved and adopted by the Compensation Committee of the Board in 2023 (“2023 MIP”). The 2023 MIP is a successor to the predecessor MIP that, by its terms, expired with the end of the 2022 bonus year. The essential attributes of the predecessor MIP are unchanged in the 2023 MIP, which, unlike the predecessor MIP, was not adopted subject to shareholder approval because of changes that were made to certain Internal Revenue Code provisions that cause shareholder approval to be unnecessary. The 2023 MIP will continue in effect until terminated by the Compensation Committee or the Board.

Target MIP

The Compensation Committee, with assistance from its independent compensation consultant, established target MIP levels for 2025 for the NEOs. These targets, shown below, were determined to be competitive generally relative to market median targets for executives with comparable positions within our peer group. The target MIP percentages for Mr. Miller and Mrs. Tillman were increased to 150% and 135%, respectively, to align their target MIP competitively relative to similar roles in the market. The targets for the other NEOs remained unchanged from 2024.

The MIP payouts for the NEOs cannot exceed two times their target.

2025 MIP Targets and Actual Performance

Corporate Metric

Adjusted earnings per diluted share on a currency-neutral basis for the full year came in at $7.46 per share, and the MIP definition of the metric increased the achieved result to $7.52 on a currency-neutral basis, resulting in a maximum payout for 2025. The net increase of $0.06 based on the MIP definition was primarily due to variable net investment income being capped at +/- 10% of our long-term return expectation. Actual results were below the floor, resulting in a positive $0.06 adjustment.

U.S. Segment Metrics

Aflac U.S. new annualized premium sales increased 3.0%, which resulted in a payout between minimum and target for 2025. Net earned premium increased by 2.9% in 2025, which resulted in a payout slightly below target for 2025.

Japan Segment Metrics

Aflac Japan’s new annualized premium sales as reported was ¥74.351 billion, however, an adjustment was made to decrease the result for MIP purposes to ¥74.198 billion, which resulted in a maximum payout for 2025. The reduction was made to exclude the lapse and reissue premium for Tsumitasu. Net earned premiums, excluding the impact of deferred profit liability and mid-year financial reinsurance transactions not in plan with a transaction asset threshold or a release of GAAP future policy benefits reserves threshold in excess of ¥3 billion, and earned premiums from Aflac Pet Small amount-and-Short-term Insurance Co., Ltd. that are excluded from the Company’s MIP basis, were ¥1.041 trillion (target ¥1.033 trillion) resulting in a payout between target and maximum.

Global Investments Metrics

In 2025, Aflac Global Investments produced adjusted net investment income of ¥385.8 billion for Aflac Japan and $830 million for Aflac U.S. This results in a maximum payout of 200%. Credit losses for the full year were $209 million which results in a payout between minimum and target. Aflac Global Investments continues to generate strong capital and cash flows while maintaining its commitment to prudent liquidity and capital management.

In February 2025, the Compensation Committee authorized grants of LTI variable equity awards to executive officers, including NEOs, in the form of PBRS. All eligible non-executive officers received time-based restricted stock units (“RSUs”).

In determining the number of shares of PBRS to be granted to NEOs, the Compensation Committee is advised by its independent compensation consultant. The Compensation Committee’s decision is informed by market data regarding comparable executive positions within the Company’s peer group and the broader insurance sector, and each NEO’s tenure and performance. Based on these considerations, the Compensation Committee determines award levels that it believes are competitive within the Company’s peer group and the broader insurance sector, generally targeting the market median, and will be effective at aligning the NEO’s compensation with performance and the interests of our shareholders. Future payouts (if any) on the February 2025 PBRS awards will be based on the Company’s performance from 2025 through 2027 and will vary between 0% and 200% of the target number of PBRS granted, which is consistent with typical market practices.

LTI awards will vest three years from the issuance date, generally subject to combined service and satisfaction of performance conditions and final Compensation Committee authorization.

Target LTI Awards

The pay program for the CEO follows a market-based approach. The Compensation Committee granted the CEO his target annual LTI award in February 2025 at a market-competitive level, based primarily on peer group market data. Specifically, the CEO’s target LTI was set at an amount that approximates the 50th percentile LTI of the CEOs in the Company’s peer group for 2025. This resulted in the CEO’s target LTI being 765% of his base salary.

The Compensation Committee, with assistance from its independent compensation consultant, established target LTI levels for 2025 for the other NEOs. These targets, shown below, were determined to be competitive generally relative to market median targets for executives with comparable positions within our peer group. The target LTI percentages for Mr. Brodén. Mr. Dyslin, Mr. Miller and Mrs. Tillman were increased to align their target LTI competitively relative to similar roles in the market.

2025 annual LTI award targets as a percent of base salary for the other NEOs were as shown below:

NEO			Target LTI (as percent of base salary)
Max K. Brodén			325		%
Bradley E. Dyslin			250		%
Virgil R. Miller			300		%
Audrey Boone Tillman			325		%

LTI Performance Metrics

The PBRS will vest based on the Company’s achievement on a combination of these measures—AROE, RBC, SMR/ESR —for the cumulative three-year performance period beginning January 1, 2025 and ending December 31, 2027. As described below, each metric has been assigned a weight that determines its effect on the LTI payout. Once a payout is calculated based on the weighted average achievement on a combination of these metrics, that amount will be modified (up to +/-20%) based on our RTSR.

As noted in the descriptions below, in designing the LTI program, the Compensation Committee recognizes the importance of maximizing profitability and return on equity to shareholders, but also believes it is appropriate to pursue those objectives within the context of a solid risk framework.

Metric			Compensation Committee Rationale			Weighting
Adjusted Return on Shareholders’ Equity (AROE) We define AROE (or currency neutral AROE) as: Adjusted Earnings, excluding the impact of foreign currency ÷ Adjusted Book Value*			•Enables shareholders to evaluate our financial achievements relative to other organizations in terms of how effectively we use capital to generate earnings •We believe this metric has a significant influence on the value our shareholders place on the Company			70%
Risk-Based Capital (RBC)			•Current regulatory solvency measure in the U.S. •Capital adequacy is a significant metric for the financial markets and shareholder confidence •Critical metric determining cash flow capacity in support of Common Stock dividend and share repurchase			15%
Solvency Margin Ratio (SMR)/Economic Solvency Ratio (ESR)			•Principal capital adequacy measure in Japan •Capital adequacy is a significant metric for the financial markets and shareholder confidence •Critical metric determining cash flow capacity in support of Common Stock dividend and share repurchase			15%
Total Shareholder Return Relative to Peer Group (RTSR)			•Align LTI payouts with relative performance to peer group			Modifier (up to ± 20%)

*    AROE and adjusted earnings, excluding the impact of foreign currency, and adjusted book value are not calculated in accordance with GAAP. See Appendix A to this Proxy Statement for definitions for these non-GAAP financial measures and reconciliations to the most directly comparable GAAP measures.

2025 LTI Performance Targets

The following illustrates the terms of the 2025 PBRS grant for all NEOs.

			Threshold Performance Level			Target Performance Level			Maximum Performance Level						2025- 2027
3-yr. avg. currency-neutral AROE goal			12.5%			14.5%			17.5%
3-yr. avg. RBC(1) goal			350%			400%			450%
3-yr. avg. SMR(2)/ ESR goal(3)			500%			600%			700%

Payout (% of Target)			50%			100%			200%
			×
3-yr. RTSR percentile rank vs. peer group			25th percentile or lower			Between 25th and 75th percentile			75th percentile or greater
RTSR Modifier to Earned Amounts			0.80x			1.00x			1.20x
			Payout									u			2028

(1)RBC measured on a consolidated basis.

(2)Excludes impact of unrealized gains on available for sale securities.

(3)SMR is attributable to year 2025 while ESR is attributable to years 2026 and 2027.

•For financial performance (AROE, SMR/ESR, and RBC), linear interpolation will be used to determine payouts for performance between the corresponding goals (i.e., threshold to target, or target to maximum).

•For RTSR, adjustments of 1.20x or 0.80x will be made only if the Company’s RTSR is in the upper or lower quartile, respectively, versus our peer group. There will not be any adjustments to the payout if RTSR falls between the 25th and 75th percentiles of the peer group.

•Maximum potential payouts will be capped at 200% of target number of PBRS granted.

The goals for these metrics are generally consistent with the Company’s public disclosure previously provided during the fourth quarter 2024 earnings release call.

2023-2025 Performance Period

In February 2026, the NEOs received payouts with respect to the PBRS awards that were granted in February 2023 for the three year-performance period ended December 31, 2025. For all NEOs except, Mr. Miller, these awards were paid at 172% times the target number of shares initially awarded based on the three-year average results for each of the currency neutral AROE, SMR, and RBC metrics. The Company’s TSR performance relative to the peer group was in the 47th percentile rank, and therefore a RTSR modifier of 1.00x was applied (no adjustment) to earned amounts as shown in the table below.

			A						B			A*B=C			D			C*D

For Mr. Miller, the award was paid at 135.4% times the target number of shares initially awarded based on the three-year average results for each of the currency neutral AROE and RBC metrics and the End-Point Expense Ratio metric. As noted above, the Company’s TSR performance relative to the peer group was in the 47th percentile rank, and therefore the RTSR modifier did not impact the earned amounts as shown in the table below.

Supplemental Equity Awards

From time to time, we have granted supplemental awards in the form of RSUs to incentivize achievement of strategic objectives, recognize major milestones, or secure leadership stability. Effective January 2, 2025, the Compensation Committee awarded an RSU grant to Mr. Miller in recognition of his leadership in his new role as Aflac Incorporated President as it is a critical position with the Company as we move forward. The grant will vest on the third anniversary of the grant date generally subject to continued service throughout the vesting period. On August 12, 2025, the Compensation Committee awarded an RSU grant to Mr. Dyslin in an effort to maintain competitiveness in the market for his position and to secure his leadership going forward. The grant will vest on the third anniversary of the grant date generally subject to continued service through the vesting period. For more information regarding supplemental awards, see the 2025 Grant of Plan-Based Awards table on page 61.

EXECUTIVE COMPENSATION 2026 PROXY STATEMENT 55

Other Compensation

The retirement, deferral, and savings plans described in the tables below were established in order to provide competitive post-termination benefits for officers and employees, including the NEOs, in recognition of their service and contributions to the Company.

Defined Benefit Pension Plans

As described further in “Pension Benefits” below, the Company maintains tax-qualified, noncontributory defined benefit pension plans covering substantially all U.S. employees, including the NEOs, who satisfy the eligibility requirements. The Company also maintains nonqualified supplemental retirement plans covering some of the NEOs. In June 2023, the Company amended the U.S. defined benefit plan to freeze future benefits under the plan for all participants and subsequently terminated the plan effective January 1, 2024.

Executive Deferred Compensation Plan

The NEOs, together with other U.S.-based eligible executives, are entitled to participate in the Executive Deferred Compensation Plan (“EDCP”). All NEOs currently participate in this plan. The EDCP is discussed in more detail below under “Nonqualified Deferred Compensation.” No change was made to the EDCP in 2025.

401(k) Savings and Profit Sharing Plan

The Company maintains a tax-qualified 401(k) Savings and Profit Sharing Plan (the “401(k) Plan”) in which all U.S.-based employees, including the U.S.-based NEOs, are eligible to participate on the same terms. The Company provides matching contributions equal to 100% of each employee’s contributions up to 4% of the employee’s eligible annual cash compensation. Employee contributions made to the 401(k) Plan are 100% vested. Employees vest in Company contributions at the rate of 20% for each complete year of service. After five years of service, employees are fully vested in all Company contributions.

All NEOs are eligible to receive a nonelective contribution of 4% of annual compensation. Effective January 1, 2024, the nonelective 401(k) employer contribution was extended to U.S. employees who were participants in the defined benefit plan prior to the freeze of future benefits on January 1, 2024.

Other Benefits

The Company provides NEOs with other benefits that we believe are reasonable, competitive, and consistent with our overall executive compensation program. For details, see the “All Other Compensation” column in the 2025 Summary Compensation Table on page 59. The Company maintains medical and dental insurance, group life insurance, accidental death insurance, cancer insurance, and disability insurance programs for all employees, as well as paid time off, leave of absence, and other similar policies. The U.S.-based NEOs and other officers are eligible to participate in these programs along with, and on the same basis as, the Company’s other salaried employees. In addition, the NEOs are eligible to receive reimbursement for medical examination expenses.

For security and time-management reasons, certain officers of the Company occasionally travel on corporate aircraft for business and personal purposes. Personal travel on corporate aircraft and security services are provided where considered by the Board to be in the best interest of the Company and its business objectives.

Additional Executive Compensation Plan Practice and Procedures

Stock Ownership Guidelines; Insider Trading Policy; Hedging and Pledging Restrictions

The Company believes its senior officers and Directors should have a significant equity interest in the Company and has enforced stock ownership guidelines for senior officers and Non-employee Directors since 1998. The stock ownership guidelines, as most recently amended on February 15, 2024, are as follows:

Position

Ownership guideline

What Counts

What Does Not Count

Chairman of the Board/CEO

8x base salary

Ownership includes all shares beneficially owned by the officer or Non-employee Director, as well as time-based, unvested restricted shares.

PBRS and stock options (vested or unvested) do not count toward these stock ownership guidelines.

President of Aflac Incorporated

5x base salary

Chairman/President of Aflac U.S.

4x base salary

Chairman/President of Aflac Japan

4x base salary

All other Section 16 Officers

3x base salary

Non-Section 16 Executive Vice Presidents and Senior Vice Presidents

1x base salary

Vice Chairman of Aflac Japan

1x base salary

Non-employee Directors

5x annual cash retainer

Compliance Period

Officers have four years from their hire or promotion date to satisfy their respective stock ownership requirements. Non-employee Directors have five years from the date first elected to the Board to satisfy these requirements. Upon any increase in these stock ownership guidelines or an increase in base salary or annual cash retainer, impacted individuals will have an additional two years from the effective date of the change to comply with the increased requirements.

Compliance Status

Each current NEO and Non-employee Director has stock ownership that exceeds the ownership guidelines or is working toward meeting the requisite guideline within the allowed time frame. Progress toward meeting the guidelines is reviewed regularly and reported to the Board.

Insider Trading Policy and Compliance Procedures

The Company has adopted an Insider Trading Policy and Compliance Procedures which governs the purchase, sale and other dispositions of the Company's securities by its board members, officers, directors, employees and other covered persons as well as by the Company itself. The Company believes that this policy is reasonably designed to promote compliance with insider trading laws, rules and regulations, and listing standards applicable to the Company. The Company’s insider trading policy prohibits our Non-employee Directors, officers and other covered individuals from purchasing financial instruments (including derivatives and exchange funds), or otherwise engaging in transactions that hedge or offset, or are designed to hedge or offset, any decrease in the market value of our Common Stock (collectively, “hedges”), or entering into a 10b5-1 plan unless that plan is approved by the Compensation Committee. In addition, executive officers and Non-employee Directors are prohibited from pledging the Company’s stock. All other covered individuals under the Company’s insider trading policy must obtain preapproval from the policy’s compliance officer before pledging Company stock as collateral for a margin account or other loan. The Company’s anti-hedging policy prohibits all employees from engaging in hedges. A copy of Company’s Insider Trading Policy and Compliance Procedures was filed as Exhibit 19 to its Annual Report on Form 10-K for the year ended December 31, 2024.

Employment Agreements

The Company has employment agreements with the NEOs (other than Mr. Dyslin and Mr. Miller) and certain other executives in key roles. The agreements generally address role and responsibility; rights to compensation and benefits during active employment; termination in the event of death, disability, or retirement; termination for cause or without cause; and resignation by the employee. Some agreements also contain termination and related pay provisions in the event of a change in control. These change-in-control provisions do not apply unless there is both a change in control and either a termination by the Company without cause or a resignation by the executive for good reason. This is commonly referred to as a “double trigger” requirement. No agreement provides for excise tax gross-ups. Further, each agreement stipulates that the subject executive may not compete with the Company for a prescribed period following termination of employment, or disclose confidential information. Mr. Amos has voluntarily waived all “golden parachute” and other severance components in his employment agreement. The payments that may be made under each NEO’s employment agreement upon termination of employment under specified circumstances are described in more detail below under “Potential Payments Upon Termination or Change in Control.”

EXECUTIVE COMPENSATION 2026 PROXY STATEMENT 57

Change-in-Control Policy

The Company has no formal change-in-control policy. However, some individual employment agreements (as noted above) and the executive severance plan incorporate provisions related to change in control.

Severance Plan

The Company maintains an executive severance plan (“ESP”) that provides severance compensation to certain senior level employees. The ESP is designed to alleviate the financial hardships that may be experienced by executive employee participants whose employment is involuntarily terminated by the Company for any reason other than Cause or disability, or voluntarily terminated by the employee for Good Reason, as those terms are defined in the ESP. Mr. Dyslin and Mr. Miller are the only NEOs covered by the ESP.

Compensation Recovery (“Clawback”) Policy

The Company has long maintained a “clawback” policy to allow the Company to recover compensation paid to certain officers in appropriate circumstances. That policy has now been revised to not only comply with the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, SEC rules, and the NYSE listing requirements, but also includes additional triggers for potential recoupment of incentive-based compensation due to such officer’s detrimental conduct by as defined by the policy. The Compensation Committee is charged with determining whether such recovery is required or appropriate, the amount to be recovered and the officer group to be affected. The Compensation Committee and the Board will continue to monitor developments in this area to consider practices as they evolve.

Compensation Risk Assessment

Following the end of 2009, the SEC required public company proxy filings to include disclosures on any practices and policies related to compensation posing material risk to a company. This assessment serves as a review of the practices and policies surrounding compensation and governance to evaluate if any material risk is placed on an organization and is reviewed by the Compensation Committee as part of its standard oversight responsibilities. For purposes of the Company’s compensation risk assessment, the following nine “standard’ program design elements/categories were analyzed:

Compensation Risk Considerations

Pay mix			•Balanced approach between cash and equity •MIP and LTI (PBRS) plan designs and target levels are benchmarked annually to relevant market comparables
Performance metrics			•MIP and LTI (PBRS) metrics provide a balance between short-term, mid-term, and longer-term performance objectives - use of multiple metrics help ensure performance on one metric is not “over-emphasized” •MIP’s metrics reflect a balanced, multi-faceted approach to performance assessment: (1) Corporate objectives (adjusted EPS), (2) U.S. and Japan business segment objectives (new annualized premium sales and net earned premium for NEOs; other U.S. Officers also have adjusted expense ratio and pre-tax adjusted earnings), (3) Global Investments metrics (net investment income; credit loss/impairments), and (4) sustainability-related goals •PBRS program generally focuses on Currency-neutral Adjusted Return on Shareholders’ Equity (AROE) EX-FX, RBC, and SMR/ESR. Relative TSR modifier to financial results provides a “market check” for alignment with shareholders •Business unit leaders are linked to overall Company performance via plan designs
Goal Setting and Payout Curves			•Rigorous goal-setting process conducted by 100% independent Compensation Committee, with final metrics, goals, and payouts approved by the Compensation Committee •Payouts for both MIP ($s) and PBRS (# of shares/units) programs are capped at 200% of target - - 200% of target maximum payout levels are within typical market practices
Payment Timing & Adjustments			•Payments for both MIP and LTI (PBRS) programs are approved following review of performance results by Compensation Committee •Adjustments to actual results are defined and include reasonable items, with consistent treatment from year to year

58 AFLAC INCORPORATED EXECUTIVE COMPENSATION

Equity Incentives			•Equity-based LTI grants provide alignment with multi-year performance horizon and long-term value creation •PBRS’s design includes multiple metrics to measure performance holistically versus placing emphasis on a single metric’s performance •Target grant levels are benchmarked regularly to assess competitiveness •Run rate and overhang are reviewed regularly to ensure appropriate management and usage of equity share pool •Stock incentive plans prohibit option repricing or buy-outs without stockholder approval
Risk mitigation policies			The Company maintains the following policies: •Meaningful stock ownership guidelines •Clawback policy •Anti-hedging policy •Anti-pledging policy •Caps on incentive plan payments (relative to target amounts) – described previously
Individual Performance Assessment			•Individual performance is assessed in certain limited circumstances to adjust MIP results; individual performance is also a factor when determining size of target LTI grants •Inappropriate behavior and unacceptable risk-taking would be incorporated into an individual’s compensation evaluation process
Severance/Change-In-Control Policies			•Double trigger change-in-control severance agreements (cash and equity) •No excise tax gross-ups from M&A activity or terminations •No liberal definition of “change-in-control”
Leadership and Culture			•Company culture, combined with individual performance evaluation process and other key program design elements, mitigate unnecessary or excessive risk-taking behavior •Regular review of Company policies by the Board, Compensation Committee, and Company Leadership helps ensure best practices are maintained

Based on this review, the Compensation Committee determined that the Company’s compensation practices and policies for its employees are not reasonably likely to have a material adverse effect on the Company.

Certain Tax and Accounting Implications of Executive Compensation

In evaluating the Company’s executive compensation structure, the Compensation Committee considers the tax and accounting treatment, balancing the effects on the individual and the Company. The Compensation Committee believes that the potential deductibility and the accounting treatment of the compensation payable under those programs should be only one of a number of relevant factors taken into consideration, and not the sole or primary factor, in establishing the cash and equity compensation programs for the executive officers. Section 162(m) of the Internal Revenue Code (“Section 162(m)”) generally limits to $1.0 million the amount of remuneration that the Company may deduct in any calendar year for certain executive officers. While the Compensation Committee considers the effect of the Section 162(m) deduction limit and financial accounting implications when designing the Company’s compensation programs, the Compensation Committee’s primary focus in its compensation decisions will remain on most productively furthering the Company’s business objectives and not on whether the compensation is deductible or its accounting treatment. Accordingly, the Compensation Committee will continue to maintain flexibility and the ability to pay competitive compensation by not requiring all compensation to be deductible or to be subject to any particular accounting treatment.

Compensation Committee Report

The Compensation Committee has reviewed and discussed the preceding CD&A with management and, based on that review and discussion, has recommended to the Board to include the CD&A in this Proxy Statement, which will be incorporated by reference into the Company's Annual Report on Form 10-K filed with the SEC for the year ended December 31, 2025.

*      Total without Change in Pension Value represents total compensation, as determined under applicable SEC rules, minus the change in pension value reported in the Change in Pension Value and Nonqualified Deferred Compensation Earnings column. This additional column has been included to show the effect that the year-over-year change in pension value had on total compensation as determined under applicable SEC rules. The amounts reported in the Total without Change in Pension Value column differ from the amounts reported in the Total column required under SEC rules and are not a substitute for total compensation. The change in pension value, as discussed in footnote 3 below, is subject to many external variables that are not related to the Company’s performance.

(1)In each of the three years above, includes $441,100 deferred for Mr. Amos. This amount is included in the 2025 Nonqualified Deferred Compensation table below. See “Elements of Our Executive Compensation Program — Base Salary” in the Compensation Discussion and Analysis section of this Proxy Statement for information about adjustments to base salaries in 2025.

(2)In accordance with the SEC’s reporting requirements, we report all equity awards at their full grant date fair value under ASC 718 at target-level performance for PBRS, which is the probable achievement level of the performance conditions. The Company’s valuation assumptions are described in Note 12, “Share-Based Compensation,” in the Notes to the Consolidated Financial Statements in the Company’s Annual Report on Form 10-K filed with the SEC for the year ended December 31, 2025. See “Elements of Our Executive Compensation Program — Long-Term Incentives” in the Compensation Discussion and Analysis section of this Proxy Statement for additional information about these long-term incentives and their terms. Assuming achievement of performance goals at the maximum level, the aggregate grant date fair value of the PBRS would be: Daniel P. Amos, $22,681,564; Max K. Brodén, $6,185,362; Bradley E. Dyslin, $3,755,080; Virgil R. Miller, $5,092,380; and Audrey Boone Tillman, $5,516,816. See “2025 Outstanding Equity Awards at Fiscal Year-End” beginning on page 62 for a more details of our outstanding equity grants compared to fair market value as of December 31, 2025.

(3)No amount in this column is attributable to above-market earnings on deferred compensation. Mr. Brodén is not eligible to participate in the Company’s defined benefit plans because the plans were frozen to new participants before he joined the Company.

(1)Perquisites are more fully described in the following 2025 Perquisites table.

(2)The $28,400 shown in "Company Contributions to 401(k) Plan” for Mr. Dyslin includes $400 of employer contributions that exceeded plan limits and which were removed, along with associated earnings, from the participant’s account in 2026.

2025 Perquisites

The following table identifies the incremental cost to the Company of each perquisite included for 2025 in the All Other Compensation table.

Name			Personal Use of Company Aircraft(1) ($)			Security Services(2) ($)			Other(3) ($)			Total Perquisites and Other Personal Benefits(4) ($)

Virgil R. Miller			—			—			2,517			2,517
Audrey Boone Tillman			—			—			472			472

(1)Incremental cost for the personal use of corporate aircraft is the calculated standard hourly cost rate based upon actual operating expenses for corporate aircraft, including fuel costs, airport fees, catering, in-flight phone, crew travel expenses, and maintenance cost. This rate is recalculated annually. The personal use of corporate aircraft has been authorized by the Board for security reasons and to maximize the effectiveness of the executives’ time. No incremental cost for personal use of the corporate aircraft was attributed to an NEO where the aircraft was already traveling to the destination for business reasons.

(2)Incremental costs for security services include the salaries and benefits of security officers and the actual costs of any security equipment, monitoring, and maintenance fees. While SEC rules require that these expenses be reflected as compensation for our NEOs, the Company and the Board believe that providing personal security services for its NEOs in response to concerns arising out of employment by the Company is a business related expense.

(3)Amounts included in the Other column include charges incurred by Mr. Miller and Mrs. Tillman for guest travel, by Mr. Brodén totaling $48,141 for personal tax return preparation and/or financial planning, and by Mr. Dyslin for guest travel and Company paid car service.

(4)The Company did not gross up for tax purposes any of the perquisites described in this table.

(1)The amounts shown in Estimated Possible Payouts Under Non-Equity Incentive Plan Awards reflect the payout levels for the NEOs under the Company’s MIP, based on the potential achievement of certain performance goals approved by the Compensation Committee on March 4, 2025. For additional information, please see “Elements of Our Executive Compensation Program—Management Incentive Plan” beginning on page 47. For each Company performance goal, a minimum, target, and maximum performance level is specified. The amount paid for each performance goal depends on the results attained.

(2)The amounts shown under Estimated Future Payouts Under Equity Incentive Plan Awards for reflect the number of shares granted. Those shares incorporate restrictions that will lapse upon the attainment of performance goals set by the Compensation Committee. For all NEOs, awards vest on the third anniversary of the grant date, based on the attainment of the cumulative three-year average target performance goals for Company AROE and the RBC and SMR/ESR ratios. For the cumulative three-year average performance period from 2025 to 2027 for all NEOs, the PBRS awards will vest at 50% of target if the Company attains the minimum goals and at 200% if the Company reaches or exceeds the maximum goals. Earned amounts may then be modified based on the Company’s TSR performance versus our peer group, but not in excess of the 200% vesting described above. All NEOs possess the same rights as all other holders of Common Stock in respect of the shares underlying the PBRS awards, including all incidents of ownership (except the right to transfer the shares while they remain subject to forfeiture) and the right to vote such shares. The dividends accrued on the shares subject to the PBRS awards will be reinvested in Common Stock at the same dividend rate received by other holders of Common Stock. Those additional restricted shares will be held in book entry form in the custody of the Company subject to the same terms and conditions attributable to the original grant until such time as all restrictions have lapsed on the shares of Common Stock with respect to which the dividend was accrued.

(3)The amounts reported in this column will vest on the third anniversary of the grant date generally subject to continued service through the vesting period.

Pension Benefits

The Company maintained a tax-qualified, noncontributory defined benefit pension plan that covered the NEOs other than Mr. Brodén, and continues to maintain nonqualified supplemental retirement plans covering the NEOs other than Messrs. Brodén, Dyslin and Miller. All of these plans were frozen before Mr. Brodén joined the Company. In June 2023, the Company amended the U.S. defined benefit plan to freeze future benefits under the plan for all participants and terminated the plan effective January 1, 2024. In January 2025, the Company purchased a nonparticipating single premium group annuity contract for participants who did not participate in the lump sum opportunities from an external insurer to settle its obligations under the U.S. defined pension plan and paid to the insurer the related annuity premium. Effective April 1, 2025, the external insurer began making annuity payments to plan participants.

The Company does not credit extra years of service under any of its retirement plans, unless required by employment agreements upon certain termination events. Mr. Amos is eligible to receive immediate retirement benefits, which fall under the provisions of the Retirement Plan for Senior Officers. Mrs. Tillman is eligible to receive immediate retirement benefits, which fall under the provisions of the U.S. Supplemental Executive Retirement Plan.

64 AFLAC INCORPORATED EXECUTIVE COMPENSATION

Executive Retirement Plan

Currently, Mrs. Tillman is the only active NEO who participates in the Company’s U.S. Supplemental Executive Retirement Plan (“SERP”), which is an unfunded and unsecured obligation of the Company and is not a tax-qualified plan. The SERP provides retirement benefits to certain officers of the Company in addition to those provided by the qualified Plan. Participation in the SERP is limited to certain key employees as periodically designated by the Compensation Committee. To be eligible for benefits under the SERP, participants generally must be employed with the Company or a subsidiary at age 55. The SERP was frozen to new participants effective January 1, 2015, and additional accruals were frozen as of December 31, 2023, provided that actively employed participants may continue to accrue service toward eligibility for early retirement benefits or delayed early retirement benefits.

The SERP includes a four-tiered benefit formula that provides for a benefit based on final three-year average compensation (base salary and non-equity incentive plan compensation) earned for a calendar year as described below. The annual benefit varies based on the participant’s age at retirement: 40% is paid to someone who retires between the ages of 55 and 59, 50% is paid to someone who retires between the ages of 60 and 64, and 60% is paid to someone who retires at or after the age of 65. A reduced 30% benefit is available to participants with at least fifteen years of service who terminate employment prior to age 55. Mrs. Tillman has met the SERP retirement benefit level of 50%.

Benefits generally are payable in the form of an annuity for the life of the participant. The participant may elect to receive reduced lifetime benefits, in which case any surviving spouse will receive a benefit equal to 50% of the amount paid to the participant. Benefits are calculated based upon the average annual compensation for the three consecutive calendar years out of the final ten consecutive calendar years of employment that yield the highest average. Benefits under the SERP are subject to offset for amounts paid under the qualified Plan.

Retirement Plan for Senior Officers

The CEO is the only active employee who participates in the Retirement Plan for Senior Officers (“RPSO”), which is an unfunded and unsecured obligation of the Company and is not a tax-qualified plan. Participants in the RPSO receive full compensation (base salary and MIP) for the first twelve months after retirement. Thereafter, a participant may elect to receive annual lifetime retirement benefits equal to 60% of final compensation (base salary plus non-equity incentive), or 54% of final compensation with 50% of final compensation to be paid to a surviving spouse for a specified period after death of the participant. Final compensation is deemed to be the higher of either (i) the compensation paid during the last twelve months of active employment with the Company, or (ii) the highest compensation received in any calendar year of the last ten years preceding the date of retirement.

Generally, no benefits are payable until the participant accumulates ten years of credited service at age 60, or twenty years of credited service. Reduced benefits may be paid to a participant who retires (other than for disability) before age 65 with less than twenty years of credited service. Mr. Amos has 50 years of credited service, meaning he is fully vested for retirement benefits under the RPSO. The RPSO was frozen to new participants on January 1, 2009, and additional accruals were frozen as of December 31, 2023.

All benefits under the RPSO are subject to annual cost-of-living increases as approved by the Compensation Committee. Retired participants and their spouses also are entitled to receive full medical expense benefits for their lifetimes. The benefits payable under the RPSO are not subject to Social Security or qualified Plan offsets.

2025 Pension Benefits

The following table provides certain information regarding the Company’s pension benefits at December 31, 2025, and for the year then ended. Mr. Amos and Mrs. Tillman are the only NEOs that participate in the Company’s pension plan.

(1)Assumptions used to calculate pension benefits are based on GAAP assumptions, as more fully described in Note 14, “Benefit Plans,” in the Notes to the Consolidated Financial Statements in the Company’s Annual Report on Form 10-K filed with the SEC for the year ended December 31, 2025, except that, for Mrs. Tillman, the assumed retirement age is the earliest retirement age for unreduced benefits and, for Mr. Amos, who has exceeded such age, is his actual expected retirement age as determined for GAAP purposes.

(1)The $1,999,359 for Mr. Amos includes $441,100 in compensation deferred at the direction of the Compensation Committee and is included in the Salary column of the Summary Compensation Table for the current year. The funds are 100% vested. The remaining $1,558,259 represents vested Company-funded contributions in the amount of 20% of his annual compensation (base salary plus MIP).

(2)The $745,320, $549,381 and $521,969 deferred compensation for Messrs. Brodén, Miller, and Tillman represents unvested Company-funded contributions in the amount of 20% of their annual compensation (base salary plus MIP). The $506,483 deferred compensation for Mr. Dyslin represents unvested Company-funded contributions in the amount of 15% of his annual compensation (base salary plus MIP). The funds for 2025 were credited to the EDCP in March 2026. This is an annual contribution approved by the Compensation Committee. Annual contributions will be 100% vested on the earlier of (i) the later of 15 years of employment or 5 years participation, (ii) age 65, (iii) change in control, (iv) death, or (v) disability. The amount shown in the table is included in the Summary Compensation Table for the current year in the All Other Compensation column. Additionally, previous years’ deferrals included in the Aggregate Balance column were reported as compensation in prior periods.

(3)The Company does not pay or credit above-market earnings on amounts deferred by or on behalf of executives.

(4)Distributions for Mr. Dyslin were made in accordance with his elections under the EDCP on amounts deferred from his compensation.

(5)The amounts reported represent balances from the EDCP and include various amounts previously reported in the Summary Compensation Table as Salary, Non-equity Incentive Plan Compensation or All Other Compensation.

The EDCP allows certain U.S.-based officers, including the NEOs (the “Participants”), to defer up to 75% of their base salaries and their annual non-equity incentive awards. The Company may make discretionary matching or other discretionary contributions in such amounts, if any, that the Compensation Committee may determine each year.

Portions of the EDCP are subject to Section 409A of the Internal Revenue Code (“Section 409A”) with respect to deferred amounts that became earned and vested on or after January 1, 2005. Deferred amounts earned and vested prior to 2005 (“grandfathered” amounts) under the EDCP are not subject to Section 409A’s requirements and continue to be governed generally under the terms of the EDCP and the tax laws in effect before January 1, 2005. All NEOs have met the applicable vesting requirements with the exception of Messrs. Brodén and Dyslin.

The amounts in the Aggregate Balance at Last Fiscal Year-End column include investment earnings (and losses) determined under phantom investments. Account balances may be invested in phantom investments selected by Participants from an array of investment options that substantially mirror the funds available under the Company’s 401(k) Plan, except for Common Stock. Participants can change their investment selections (unless prohibited by the fund) in the same manner that applies to participants in the 401(k) Plan.

Each year, when Participants elect whether to defer compensation under the EDCP for the following year, they also elect the timing and form of future distributions arising from those deferrals, with a separate election permitted for each type of deferral (i.e., salary and non-equity incentive award). Specifically, a Participant may elect distributions beginning in a specific year (even if employment has not then ended) or beginning six months after the termination of employment. Participants may choose to have any distribution made in a lump sum or in up to ten annual installments. Employee deferrals are 100% vested. Distributions attributable to discretionary contributions are made in the form and at the time specified by the Company.

A Participant may delay the timing and form of distributions attributable to deferrals as long as the change is made at least twelve months before the initial distribution date. With respect to non-grandfathered amounts, new elections also must satisfy the additional requirements of Section 409A. In general, Section 409A provides that distributions may not be accelerated (other than for hardships) and any delayed distribution may not begin earlier than five years after the original distribution date.

Deferral amounts for which no distribution elections have been made are distributed in a lump sum six months after a Participant separates from service.

Potential Payments Upon Termination or Change in Control

The Company has employment agreements with each of the NEOs with the exception of Mr. Dyslin and Mr. Miller, who are the only NEO participants in the Company’s Executive Severance Plan. Except as described below, the employment agreements are similar in nature and contain provisions relating to termination, disability, death, and a change in control of the Company.

Mr. Amos has voluntarily waived all “golden parachute” and other severance components in his employment agreement. The elimination and absence, respectively, of these potential payments are reflected in the 2025 Potential Payments Upon Termination or Change in Control table.

For Mr. Brodén and Mrs. Tillman, the Company remains obligated to continue compensation and benefits for the scheduled term of the agreement if the NEO’s employment is terminated by the Company without “good cause” or by the NEO with “good reason.” The remaining term for each of these NEOs as of December 31, 2025, is as follows: Mr. Brodén, 28 months; and Mrs. Tillman, 29 1/3 months. In addition, upon a termination by the Company without “good cause” or by any of the NEOs (including Mr. Amos) for “good reason,” all outstanding equity awards become fully vested, except that equity awards of the NEOs subject to Company performance will remain subject to that performance.

If an NEO’s employment is terminated by the Company for “good cause,” or by the NEO without “good reason,” the Company generally is obligated to pay compensation and benefits only to the extent accrued by the date of termination. Under the employment agreements of Mr. Brodén and Mrs. Tillman, “good cause” generally means the Company has determined that any of the following have occurred or exist: (i) the willful failure by the NEO to substantially perform assigned management duties (other than due to sickness, injury, or disability); (ii) intentional conduct by the NEO causing substantial injury to the Company; or (iii) the NEO’s conviction of or plea of guilty to a felony. Under the employment agreements of Mr. Brodén and Mrs. Tillman, “good reason” unrelated to a change in control generally is defined to include (i) a material reduction in the NEO’s base salary or bonus opportunity, which is not made for all similarly situated executives; (ii) a termination of the employment agreement other than as permitted by its terms; or (iii) a material relocation of the Company’s principal offices. Upon voluntary termination without “good reason” or termination by the Company for “good cause,” Mr. Brodén and Mrs. Tillman are prohibited for a two-year period from directly or indirectly competing with the Company.

The NEOs’ employment agreements provide that compensation and benefits continue for certain specified periods in the event the NEO becomes totally disabled. Upon the death of an NEO, the NEO’s estate is to be paid an amount, over a three-year period, equal to the NEO’s base salary and any non-equity incentive awards actually paid during the last three years of the NEO’s life. In addition, all outstanding equity awards will be honored and vest upon the date of death or disability.

Upon a “change in control” of the Company, employment agreements for Mr. Brodén and Mrs. Tillman are extended for an additional three-year period beginning with the month in which the change in control occurs. If, following a “change in control,” the employment of Mr. Brodén or Mrs. Tillman is terminated by the Company without “good cause” or by the NEO for “good reason,” the Company must pay to the NEO, among other payments but in lieu of any further salary payments, a lump-sum severance payment equal to three times the sum of the NEO’s base salary and non-equity incentive award under the MIP (as paid during periods specified in the agreement). “Good reason” for the 24-month period immediately following a change in control generally is defined to include (i) a material breach of the employment agreement by the Company in regard to compensation or benefits, or termination of the employment agreement; (ii) a material diminution or change in the NEO’s title, duties, or authority; (iii) a material relocation of the Company’s principal offices; or (iv) the failure of the Company’s successor to assume the employment agreement. Amounts payable upon a “change in control” will be reduced to the extent they are not deductible by the Company for income tax purposes. If, following a “change in control,” the employment of an NEO is terminated by the Company without “good cause” or by the NEO for “good reason,” all of Mr. Brodén and Mrs. Tillman’s outstanding equity awards will become fully vested, and all performance criteria will be considered satisfied at the maximum performance level.

A “change in control” generally is deemed to occur when (i) a person or group acquires ownership of 50% or more of the Common Stock; (ii) a person or group acquires ownership of 30% or more of the Common Stock over a consecutive twelve-month period; (iii) during any period of twelve consecutive months, a majority of individuals who constitute the Board are replaced without endorsement by a majority of the Board members at the beginning of the period; or (iv) a person or group acquires ownership of 40% or more of the total gross fair market value of the Company’s assets.

Mrs. Tillman is a fully vested participant in the SERP and is the only NEO in the SERP. Under the SERP, in the event the Company terminates a participant’s employment within two years after a “change in control” other than for “Cause,” or a participant terminates employment during such period for “good reason,” the participant will be entitled to receive a lump-sum amount equal to the actuarial equivalent of the annual retirement benefit to which she would have been entitled. Mrs. Tillman has met the SERP delayed early retirement benefit level of 50%. A “change in control” will be deemed to occur under the same circumstances described above, but only with respect to the Company. “Cause” for this purpose generally means (i) the participant’s continued failure to substantially perform her duties with the Company (other than due to illness or after a participant gives notice of termination of employment for “good reason”) after a written demand for substantial performance is delivered to the participant by the Board, (ii) the participant’s engaging in conduct materially injurious to the Company, or (iii) the participant’s conviction of, or plea of guilty or no contest to, a felony or crime involving moral turpitude. “Good reason” is generally defined for this purpose to include various adverse changes in employment status, duties, or compensation and benefits following a “change in control.”

EXECUTIVE COMPENSATION 2026 PROXY STATEMENT 67

Messrs. Dyslin and Miller are participants of the Company’s Executive Officer Severance Plan. Under this ESP, Messrs. Dyslin and Miller will incur an eligible termination, and therefore will be eligible to receive benefits under the ESP, if they incur a separation from service, because (i) their employment is involuntarily terminated by the Company for any reason other than “Cause” or disability; or (ii) they terminate their employment due to “Good Reason.” Upon Messrs. Dyslin and Miller’s eligible termination that occurs outside of the 24-month period immediately following a Change in Control, they will receive an amount equal to 150% of the total of (i) their base salary, and (ii) the dollar amount of their annual MIP bonus for the year in which their termination date occurs with performance deemed at target, plus a cash payment equal to the product of (i)the dollar amount of their annual performance bonus for the year in which their termination date occurs based on their performance at target and on the actual performance of the Company for the year in which their termination date occurs and (ii) a fraction, the numerator of which is the number of days during the annual performance period for such bonus through and including their termination date, and the denominator of which is 365. They will also be eligible to receive a cash amount equal to the COBRA continuation coverage premiums that would be payable by them for the first 18 months of the COBRA continuation period, determined as if (i) they were to elect COBRA continuation coverage for themselves and their spouse and dependents, to the extent such individuals were covered under the Aflac group medical, dental and/or vision coverage as of their termination date, and (ii) the cost of such COBRA coverage is measured as of their termination date assuming such cost remains constant during such 18-month period. “Cause” unrelated to a Change in Control generally means (i) confession to, pleas of nolo contendere to, or conviction of, a felony or other crime involving dishonesty; (ii) certification of materially inaccurate financial or other information pertaining to the Company with actual knowledge of such inaccuracies; (iii) material violation of the Company’s policies, the directions of the Board or CEO, or any agreement relating to the restrictive covenants; (iv) habitual and material negligence in the performance of duties; and (v) material non-compliance with obligations to devote all working time to the Company’s business (other than approved vacations and other time off); (vi) willful or deliberate misconduct or fraud in the performance of duties for the Company that substantially injures or damages the Company; or (vii) willful or deliberate failure to substantially perform duties, except due to sickness, injury or disability. “Good Reason” unrelated to a Change in Control generally is defined to include (i) a material reduction in the executive’s base salary or bonus opportunity; or (ii) a relocation beyond 25 miles from the participants current office location.

Upon an executive’s eligible termination that occurs on or within the 24-month period immediately following a Change in Control, they will receive an amount equal to 300% of the total of (i) their Base Salary as of their termination date, and (ii) the dollar amount of MIP Bonus for the year in which their termination date occurs with performance deemed to be at target, plus an amount equal to the product of (i) the dollar amount of their annual performance bonus for the year in which their termination date occurs with their and the Company’s performance deemed to be at target, and (ii) a fraction, the numerator of which is the number of days during the annual performance period for the bonus through and including their termination date, and the denominator of which is 365. All of their shares of unvested time-based equity awards will vest upon their termination date. All of their shares of unvested performance-based equity awards will vest as of their termination date with such number determined based on the assumptions that their and the Company’s performance under such awards are achieved at target on their termination date. They will also be eligible to receive a cash amount equal to the COBRA continuation coverage premiums that would be payable by them for the first 36 months of the COBRA continuation period, determined as if (i) they were to elect COBRA continuation coverage for themselves and their spouse and dependents, to the extent such individuals were covered under the Aflac group medical, dental and/or vision coverage as of their termination date, (ii) COBRA could extend for 36 months, and (iii) the cost of such COBRA coverage is measured as of their termination date assuming such cost remains constant during such 36-month period. Amounts payable upon a Change in Control will be reduced to the extent they are not deductible by the Company for income tax purposes, provided, the after-tax value of such reduced amount is greater than the full amount of his severance payments after reduction for all taxes (including excise taxes). “Cause” related to a Change in Control generally means (i) confession to, pleas of nolo contendere to, or conviction of, a felony or other crime involving dishonesty; (ii) willful or deliberate misconduct or fraud in the performance of duties for the Company that substantially injures or damages the Company; or (iii) willful or deliberate failure to substantially perform executive’s duties, except due to sickness, injury or disability. “Good Reason” related to a Change in Control generally is defined to include (i) a material reduction in the executive’s base salary or bonus or equity award opportunity; (ii) a material diminution in the executive’s authority, duties and responsibilities, (iii) the assignment of duties and responsibilities significantly inconsistent with those the executive had immediately before a Change in Control, (iv) a material diminution of the authority or responsibilities of the executive’s supervisor, (v) a material diminution in the executive’s budget, (vi) a relocation beyond 25 miles from the participants current office location, or (vii) failure to maintain the severance plan unchanged. For purposes of the severance plan, “Change in Control” generally is deemed to occur when (i) a person or group acquires ownership of 50% or more of the Common Stock; (ii) a person or group acquires ownership of 50% or more of the Common Stock over a consecutive twelve-month period; (iii) during any period of twelve consecutive months, a majority of individuals who constitute the Board are replaced without endorsement by a majority of the Board members at the beginning of the period; or (iv) a person or group acquires ownership of 60% or more of the total gross fair market value of the Company’s assets.

The following table reflects the amount of compensation payable to each of the NEOs in the event of termination of such executive’s employment under various termination scenarios. The amounts shown assume in all cases that the termination was effective on December 31, 2025, and, therefore, include amounts earned through such time and estimates of the amounts that would be paid to the NEOs upon their termination. Because a number of factors affect the nature and amount of any benefits actually paid, amounts paid or distributed may be different from those shown below. Mr. Amos and Mrs. Tillman are the only NEOs who are eligible to receive immediate retirement benefits. See “Pension Benefits” and “Nonqualified Deferred Compensation” above for more information.

As noted in the following table, the benefits provided, and requirements imposed vary with the circumstances under which the termination occurs.

(1)Mr. Brodén and Mrs. Tillman are entitled to salary continuation and non-equity incentive award payments for the remaining term of their respective employment agreements. Mr. Amos voluntarily waived his right to such payments. Health and welfare benefits would continue for the remainder of the contract term, except for Mr. Amos, who is entitled to health and welfare benefits under the RPSO. Upon severance without a change in control, Messrs. Dyslin and Miller would be entitled to an amount equal to 150% of the total of (i) their Base Salary, and (ii) the dollar amount of their annual MIP Bonus for the year in which their Termination Date occurs with performance deemed to be at target. Messrs. Dyslin and Miller would also be entitled to a cash amount equal to the COBRA continuation coverage premiums that would be payable by them for the first 18 months of the COBRA continuation period.

(2)Termination for good cause eliminates the salary continuation and non-equity incentive award obligation for the remainder of the contract period and causes a forfeiture of the executive’s participation in any supplemental retirement plan (except for Mr. Amos).

(3)Voluntary termination by the executive without good reason eliminates the salary continuation and non-equity incentive award obligations for the remainder of the contract term. In addition, Mr. Brodén’s nonvested equity awards will be forfeited. Messrs. Amos, Dyslin and Miller and Mrs. Tillman are retirement-eligible under the terms of the Company’s equity agreements and will vest in all equity awards granted at least one year before the date of his or her employment terminates (subject to satisfaction of performance goals).

(4)Any executive who competes with the Company after termination will forfeit the right to any further salary and non-equity incentive award payments, any benefits under the RPSO and the SERP, and all right to executive employer contributions under the EDCP. In addition, Mr. Brodén’s nonvested equity awards will be forfeited upon

EXECUTIVE COMPENSATION 2026 PROXY STATEMENT 69

competition. Benefits under the SERP and benefits under the EDCP attributable to executive employer contributions are subject to forfeiture if the executive discloses confidential Company information. Messrs. Amos, Dyslin and Miller and Mrs. Tillman are retirement-eligible under the terms of the Company’s equity agreements and each will vest in all equity awards granted at least one year before the date his or her employment terminates (subject to satisfaction of performance goals). Benefits disclosed under all other columns assume that the executive did not engage in competition or disclose confidential information following termination of employment.

(5)When an executive dies (other than Mr. Dyslin and Mr. Miller), the executive’s estate is entitled to receive terminal pay (paid in equal installments over 36 months) equal to the amount of the executive’s base pay and non-equity incentive award paid in the previous 36 months, or, if the executive was employed less than 36 months, the amount the executive would have been paid if he or she had survived for the full 36-month period. Additionally, retirement benefits in this column include the present value of the accumulated benefit obligation for a surviving spouse annuity under the RPSO for Mr. Amos. All NEO’s participate in the Company-funded EDCP, which is 100% vested for Messrs. Amos, Miller, and Tillman (subject to forfeiture of executive employer contributions upon termination for “good cause,” termination with competition or disclosure of confidential information) and vests at death for Messrs. Brodén and Dyslin. The NEOs and other officers also are eligible for life insurance benefits along with, and on the same basis as, the Company’s other salaried employees.

(6)Disability benefits are payable for 18 months or, if shorter, until the end of the term of the applicable agreement, while the executive (other than Mr. Dyslin and Mr. Miller) remains employed during his/ her disability. For all NEOs, any disability benefits paid in the form of salary continuation or non-equity incentive awards (as shown in the table) would be offset by the maximum annual amount allowed ($144,000) under the Company-sponsored disability income plan. All NEO’s participate in the Company-funded EDCP, which is 100% vested for Messrs. Amos and Miller and Mrs. Tillman and vests at disability for Messrs. Brodén and Dyslin.

(7)Upon termination after a change in control, Mr. Brodén and Mrs. Tillman would each be entitled to a lump-sum severance payment of three times the sum of (i) annual base salary in effect immediately prior to the change in control, and (ii) the non-equity incentive award paid in the year preceding the termination date or the year preceding the change in control, whichever amount is higher. Mr. Amos has waived his entitlement to receive a severance payment. Mr. Dyslin and Mr. Miller would be entitled to an amount equal to 300% of the total of (i) annual Base Salary as of the Termination Date, and (ii) the dollar amount of MIP Bonus for the year in which the Termination Date occurred with performance deemed to be at target.

(8)The non-equity incentive award amounts on this line do not include the 2025 non-equity incentive awards that were paid to the NEOs in February 2026 and which were nonforfeitable as of December 31, 2025, under all circumstances other than termination for competition.

(9)Amounts in this row generally include (i) the present value of the applicable benefits payable under the RPSO and the SERP, (ii) Company-funded contributions to the EDCP, and (ii) certain additional amounts determined under the executive’s employment agreement in lieu of continued participation in the Company’s broad-based retirement plans. However, amounts included in this column reflecting benefits payable under the SERP may differ from the amounts shown in the Pension Benefits table due to (i) reduced benefits payable under the RPSO due to termination with competition, (ii) reduced SERP benefits payable upon termination for “good cause,” termination with competition, or disclosure of confidential information, and (iii) reduced RPSO and SERP benefits payable due to death. Regardless of the reason for termination of employment, SERP benefits and executive employer contributions under the EDCP are forfeitable upon the executive’s disclosure of confidential Company information or competition within the Company.

(10)Amounts in this row generally represent the estimated lump-sum present value of all premiums that would be paid by the Company for applicable health and welfare benefits. The value shown for Mr. Amos includes his post-employment medical benefits under the RPSO for his life and the life of his spouse, the value of certain other welfare benefits, and non-medical fringe benefits (including office space) for his life. These amounts would not be payable if Mr. Amos engages in any activity that competes with the Company. The value of health coverage for each of Messrs. Brodén and Mrs. Tillman is the monthly cost of Company-paid premiums for active employee coverage under the health plan, multiplied by the number of months of Company-paid continued coverage for which the executive is eligible as determined under his employment agreement. For Mr. Dyslin and Mr. Miller, the amounts represent the COBRA continuation coverage premiums that would be payable by them.

(11)Amounts in this row represent the estimated value of accelerated vesting of stock options, restricted stock and RSU awards. The value for stock options was determined as follows: the excess of the per share closing price on the NYSE on the last business day of the year over the per share option exercise price, multiplied by the number of unvested option shares. The value for restricted stock and RSU awards was determined by multiplying the number of unvested stock awards by the same per share closing price used for options. The values of these awards that are performance-based assume maximum performance goals were achieved.

70 AFLAC INCORPORATED EXECUTIVE COMPENSATION

CEO Pay Ratio

The Company believes that executive pay should be internally consistent and equitable to motivate the Company’s employees and create shareholder value. To demonstrate the Company’s commitment to that principle, and as required by the Dodd-Frank Wall Street Reform and Consumer Protection Act and SEC rules adopted thereunder, we are disclosing the ratio of the annual total compensation of the Chairman and CEO, Mr. Daniel P. Amos, to the annual total compensation of the individual we have identified as the median employee for this purpose.

As determined in accordance with applicable SEC rules, for 2025, the last completed fiscal year:

•The annual total compensation of the CEO, as reported in the 2025 Summary Compensation Table included on page 59, was $25,033,687; and 

•The annual total compensation of the median employee determined on this same basis was $63,153.

Based on this information, the ratio of the annual total compensation of our Chief Executive Officer to the median of the annual total compensation of all employees is 396 to 1.

To identify the annual total compensation of the median employee, the Company first determined the compensation for all the Company’s employees other than the CEO as of December 31, 2025, taking into account the annual sum of cash wages, overtime, and bonus from payroll records, in each case determined without regard to cost-of-living adjustments. As of such date, the Company’s employee population consisted of approximately 12,856 individuals working at Aflac Incorporated and its consolidated subsidiaries, with 44% of these individuals located in the United States and 55% located in Japan. The employee population above includes part-time and temporary employees as of December 31, 2025 (excluding employees on unpaid leave as of December 31, 2025). as compared to the employee population disclosed in the December 31, 2025, Form 10-K, which includes only full-time employees. For employees located in Japan, the compensation in Japanese yen was converted to U.S. dollars using the annual weighted average exchange rate of Japanese yen to U.S. dollars of 149.32 to 1 on December 31, 2025.

The Company determined that, on this basis, the median employee was a full-time, salaried employee located in the U.S., with wages, overtime and bonus pay for the 12-month period ended December, 31, 2025, in the amount of $63,153.

With respect to the median employee, the Company then identified and calculated the elements of such employee’s compensation for the entirety of 2025 in accordance with the requirements of Item 402(c)(2)(x) of Regulation S-K (the basis for determining annual total compensation as reported in the Summary Compensation Table), resulting in annual total compensation in the amount of $63,153.

Mr. Amos has been CEO of the Company since 1990 and Chairman since 2001. His long-standing tenure, coupled with normal changes in the calculation of his pension due to discount rate changes, causes his pension value (when calculated according to Item 402(c)(2)(x) of Regulation S-K) to vary greatly from year to year, which may cause large changes in the ratio.

(8)Amounts reported have been revised to reflect the correction of formulas used in prior years related to “change in value of stock awards granted in prior years” and “change in value of vested stock awards granted in prior years” in the table below.

(9)SEC rules require certain adjustments be made to the Summary Compensation Table totals to determine the Compensation Actually Paid as reported in the Pay vs. Performance Table. CAP does not necessarily represent cash and/or equity value transferred to the applicable NEO without restriction, but rather is a value calculated under applicable SEC rules. In general, CAP is calculated as Summary Compensation Table total compensation adjusted to reflect certain changes in the fair market value of outstanding equity awards as of December 31 of the applicable year or, if earlier, the vesting date (rather than the grant date), and an adjustment for the aggregate value of service costs and prior service costs of pension benefits. No adjustment is made for dividends as dividends are factored into the fair market value of the award. The following table details these adjustments:

Year			Executive(s)			Summary Compensation Table Total			Subtract change in actuarial present value of pension			Subtract grant date fair value of stock awards granted during the fiscal year			Add aggregate value of service costs and prior service costs of pension benefits			Add year-end value of stock awards granted during the fiscal year			Add change in value of stock awards granted in prior years			Add change in value of vested stock awards granted in prior years			Compensation Actually Paid

AUDIT MATTERS

Ratification of Auditors In February 2026, the Audit and Risk Committee voted to appoint KPMG LLP, an independent registered public accounting firm, to perform the annual audit of the Company’s consolidated financial statements for fiscal year 2026, subject to ratification by the shareholders. Although ratification of the Audit and Risk Committee’s appointment of KPMG LLP by the shareholders is not required, the Board values the opinions of our shareholders and believes that shareholder ratification of the appointment is a good corporate governance practice. In the event of a negative vote on this proposal, the Audit and Risk Committee will reconsider its selection.

The Board of Directors and the Audit and Risk Committee recommend a  vote FOR the ratification of the selection of KPMG LLP.

Representatives of KPMG LLP are expected to attend the 2026 Annual Meeting of Shareholders. These representatives may make a statement if they desire to do so, and will be available to respond to appropriate questions.

Pre-Approval Policies and Procedures

The Audit and Risk Committee of the Board has considered whether the provision of the non-audit professional services is compatible with maintaining KPMG LLP’s independence and has concluded that it is. The Audit and Risk Committee pre-approves all audit and non-audit services provided by KPMG LLP in accordance with SEC rules, subject to the de minimis exceptions for non-audit services.

Audit and Risk Committee Report

Committee Membership and Governance

The Audit and Risk Committee of the Company’s Board is composed of four Directors. The Board has determined that each member of the Audit and Risk Committee is independent as defined by the NYSE listing standards and SEC rules, is financially literate, and qualifies as an audit committee financial expert as defined by SEC rules.

The Audit and Risk Committee operates under a written charter adopted by the Board. The charter, which is reviewed annually and complies with all current regulatory requirements, is available on the Company’s website, www.aflac.com, by clicking on “Investors,” then “Governance,” then “Governance Documents,” then “Audit & Risk Committee.”

Meetings in 2025

In 2025, the Audit and Risk Committee met nine times. During these meetings committee members reviewed and discussed a variety of topics with management, KPMG (the Company’s independent registered public accounting firm), the internal auditors, the chief risk officer, the general counsel, the global security and chief information security officer, and others, including the Company’s earnings releases and SEC filings related to quarterly and annual financial statements, statutory insurance financial statement filings, and the Company’s system of internal control over financial reporting, including information security policies.

The Audit and Risk Committee has discussed with, and received regular status reports from, the Company’s director of internal audit and KPMG on the overall scope and plans for their audits of the Company. The Audit and Risk Committee met with the internal auditors and KPMG, with and without management present, to discuss the results of their examinations, their evaluations of the Company’s internal controls, and the overall quality of the Company’s financial reporting.

Oversight of Internal Controls over Financial Reporting

The Audit and Risk Committee has monitored the Company’s compliance with Section 404 of the Sarbanes-Oxley Act regarding the reporting related to internal control over financial reporting. The monitoring process has included regular reports and representations by financial management of the Company, the internal auditors, and by KPMG. The Audit and Risk Committee also has reviewed the certifications of Company executive officers contained in the Annual Report on Form 10-K for the year ended December 31, 2025, as well as reports issued by KPMG related to its audit of the consolidated financial statements and the effectiveness of internal control over financial reporting.

Oversight of Independent Registered Public Accounting Firm

The Audit and Risk Committee is responsible for the appointment, compensation, retention, and oversight of the Company’s independent registered public accounting firm. In accordance with SEC rules and KPMG’s policies, audit partners are subject to rotation requirements to limit the number of consecutive years an individual partner may provide service to the Company. The maximum number of consecutive years of service as lead audit partner is five years. The process for selecting the lead audit partner for the Company pursuant to this rotation policy involves a meeting between the Chair of the Audit and Risk Committee and prospective candidates, as well as discussions with the full Audit and Risk Committee and with management.

The Audit and Risk Committee evaluates the performance of KPMG, including the senior members of the audit engagement team, each year and determines whether to re-engage KPMG or to consider other audit firms. In doing so, the Audit and Risk Committee considers:

•the quality and efficiency of the services provided;

•the firm’s global capabilities, particularly in the U.S. and Japan;

•its technical expertise;

•its tenure as the Company’s independent registered public accounting firm (KPMG has served in this capacity since 1963); and

•its knowledge of the Company’s operations and industry.

Based on this review and discussions with members of senior management, the Audit and Risk Committee concluded it was in the best interest of the Company and the shareholders to recommend KPMG to the Board to serve as the Company’s independent registered public accounting firm during 2025. Although the Audit and Risk Committee has the sole authority to appoint the independent auditors, the Audit and Risk Committee will continue its long-standing practice of recommending that the Board ask the shareholders to ratify this appointment for 2026 (see Ratification of Appointment of Independent Registered Public Accounting Firm (Proposal 3)).

76 AFLAC INCORPORATED AUDIT MATTERS

Required Disclosures

The Audit and Risk Committee also discussed with KPMG those matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board (the PCAOB) and the Commission.

•The Audit and Risk Committee received the written disclosures and the communications from KPMG required by applicable requirements of the PCAOB regarding the independent auditors’ communications with the Audit and Risk Committee concerning independence, and has discussed with KPMG its independence.

•The Audit and Risk Committee considered with KPMG whether the provision of non-audit services provided by it to the Company during 2025 was compatible with its independence.

In performing all of these functions the Audit and Risk Committee acts in an oversight capacity.

•The Audit and Risk Committee reviews the Company’s quarterly and annual reports on Form 10-Q and Form 10-K prior to filing with the SEC.

•In its oversight role, the Audit and Risk Committee relies on the work and assurances of the Company’s management, which has the primary responsibility for establishing and maintaining adequate internal control over financial reporting and for preparing the financial statements and other reports, and of KPMG, which is engaged to audit and report on the consolidated financial statements of the Company and the effectiveness of the Company’s internal control over financial reporting.

In reliance on these reviews and discussions, and the reports of KPMG, the Audit and Risk Committee has recommended to the Board, and the Board has approved, that the audited financial statements to be included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025, for filing with the SEC.

Related Person Transactions

The Company recognizes that transactions between the Company and any of its Directors or executives can present potential or actual conflicts of interest and create the appearance that decisions are based on considerations other than the best interests of the Company and its shareholders. Accordingly, consistent with our Code of Business Conduct and Ethics, it is the Company’s preference to avoid such transactions. Nevertheless, there are situations where such transactions may be in, or not inconsistent with, the best interests of the Company and its shareholders. Therefore, the Company has adopted a written policy that requires the Audit and Risk Committee to review and, if appropriate, to approve any such transactions. Pursuant to the policy, the Audit and Risk Committee will review any transaction in which the Company is or will be a participant and the amount involved exceeds $120,000 in any fiscal year, and in which any of the following had, has, or will have a direct or indirect material interest: (i) a Director or Director nominee, (ii) an executive officer, (iii) a holder of more than 5% of the Company’s outstanding shares, (iv) an immediate family member of any of these persons, or (v) any firm, corporation, or other entity in which one of these persons is employed or is a general partner or principal or in a similar position, or in which such person has a 5% or greater beneficial interest. During its review, the Audit and Risk Committee considers a number of factors, including whether the related person transaction is on terms no less favorable to the Company than may reasonably be expected in arm’s-length transactions. The Audit and Risk Committee will only approve those transactions that it determines in good faith are in, or are not inconsistent with, the best interests of the Company and its shareholders.

Each of the following ongoing transactions has been reviewed and approved by the Audit and Risk Committee:

Mr. Max K. Brodén is the Senior Executive Vice President, Chief Financial Officer of the Company. His spouse, Sabrina Pasini Brodén, has been employed with Aflac since January 2019. Prior to that, she was an independent consultant in the marketing department. She is currently a Director, Digital Marketing. In 2025, her total compensation, including salary, bonuses and other benefits, was $237,691. The compensation for Sabrina Pasini Brodén is commensurate with that of her peers.

As previously reported, on December 19, 2018, the Company, Aflac Japan and Japan Post Holdings Co., Ltd. (“Japan Post Holdings”) entered into a Basic Agreement regarding the “Strategic Alliance Based on Capital Relationship.” Pursuant to the Basic Agreement, Japan Post Holdings committed to acquire approximately 7% of the outstanding shares of the Company’s Common Stock via a trust and to treat the Company as an equity-method affiliate after application of time-phased voting rights (see the “Description of

AUDIT MATTERS 2026 PROXY STATEMENT 77

Voting Rights” section below for additional information). Further, Japan Post Holdings and Aflac Japan agreed to reconfirm existing initiatives regarding cancer insurance and make reasonable efforts to further develop initiatives related to the continued growth of cancer insurance sales, such as positioning Aflac Japan cancer insurance as a product as important as Japan Post Insurance Co., Ltd (“JPI”) products in the sales strategies of Japan Post Holdings, Japan Post Co., Ltd. (“JPC”) and JPI, promoting cancer insurance sales and managing promotion based on established sales targets. Under the Basic Agreement, Japan Post Holdings and Aflac Japan also agreed to consider new joint initiatives, including leveraging digital technology in various processes, cooperating in new product development to promote customer-centric business management, cooperating in domestic and/or overseas business expansion and joint investment in third party entities and cooperating with regard to asset management.

On February 28, 2019, the Company entered into a Shareholders Agreement (the “Shareholders Agreement”) with Japan Post Holdings; J&A Alliance Holdings Corporation, solely in its capacity as trustee (the Trustee) of J&A Alliance Trust, a New York voting trust (the “Trust”); and General Incorporated Association J&A Alliance (“General Incorporated”). Pursuant to the Shareholders Agreement, the Trustee agreed to use commercially reasonable efforts to acquire, through open market or private block purchases in the United States, beneficial ownership of approximately 7% of the Company’s Common Stock in connection with the Basic Agreement. According to a Schedule 13G/A filed by Japan Post Holdings with the SEC on January 6, 2021, as of December 31, 2020 the Trust had beneficially acquired 7.45% of the number of shares of Common Stock outstanding on October 19, 2020. Japan Post Holdings is the sole beneficiary of the Trust.

General Incorporated and Kenji Sano may each be deemed to share voting power over the shares of Common Stock owned directly by J&A Alliance Holdings Corporation, in its capacity as the trustee of the Trust, because (i) General Incorporated owns J&A Alliance Holdings Corporation and (ii) Kenji Sano owns 100% of the equity interests in General Incorporated. Japan Post Holdings may be deemed to share investment power over the shares of Common Stock owned directly by the Trustee, due to its role as the sole settlor and beneficiary of the Trust. The foregoing persons, other than the Trustee, have expressly disclaimed beneficial ownership of the shares held directly by the Trustee. The Trust has agreed not to beneficially own more than the greater of 10% of the Company’s outstanding shares and such shares representing 22.5% of the voting rights in the Company. In light of the fact that the shares acquired by the Trust, like all Aflac Incorporated shares of Common Stock, are eligible for 10-for-1 voting rights, having been held for 48 consecutive months, the Shareholders Agreement further provides for voting restrictions that effectively limit the trustee’s voting rights to no more than 20% of the voting rights in the Company and further restrict the trustee’s voting rights with respect to certain change in control transactions. Japan Post Holdings will not have a Board seat on the Company’s Board of Directors and will not have rights to control, manage or intervene in the management of the Company. The Shareholders Agreement shall remain in effect unless terminated by mutual written consent of Japan Post Holdings and the Company or upon the Trust disposing of all of its shares of Company Common Stock, or otherwise ceasing to beneficially own any shares of Company Common Stock.

Since 2008, the Company and Aflac Japan have maintained various commercial and contractual arrangements with Japan Post Holdings and certain of its affiliates. Under these arrangements, affiliates of Japan Post Holdings conduct the sale of Aflac Japan cancer insurance policies and, among other things, provide supplemental support necessary or beneficial to effectuating the sale and servicing of such policies. Aflac Japan’s cancer insurance policies issued pursuant to these contractual arrangements constituted approximately 6.7% of Aflac Japan’s earned premium for 2025, representing approximately 3.3% of Aflac Incorporated’s total consolidated earned premium for 2025. In exchange for facilitating such sales and other services including JPI’s acting as reinsurer for a certain percentage of the underwriting risk for Aflac Japan cancer insurance sold by JPC and JPI, affiliates of Japan Post Holdings collectively received approximately $102 million in commission and other payments from Aflac Japan and its affiliates during 2025.

(1)The above information is derived from Form 3 and Schedule 13G/A filings with the SEC, filed February 13, 2026, by Japan Post Holdings Co., Ltd.; January 7, 2026, by The Vanguard Group; and filed January 26, 2024, by BlackRock, Inc. According to the Schedule 13G/A filings: The Vanguard Group has shared voting power with respect to 3,018,037 shares, sole dispositive power with respect to 52,252,431 shares and shared dispositive power with respect to 4,888,696 shares, and BlackRock, Inc. has sole voting power with respect to 38,238,081 shares and sole dispositive power with respect to 42,164,887 shares.

(2)Percent of Class is calculated by dividing the number of shares of Common Stock beneficially owned by the number of outstanding shares of Common Stock as of February 24, 2026 (record date).

(3)Percent of Available Votes is an assumed figure calculated by dividing the number of respective voting rights by the total number of available votes based on the Company’s records of outstanding shares of Common Stock as of February 24, 2026 (record date). Shares of Common Stock held in “street” or “nominee” name are presumed to be entitled to one vote per share. The actual total number of available votes, which is dependent upon affidavits received from holders of shares held in “street” or “nominee” name, will be determined and certified by the Inspector of Election at the Annual Meeting. See the “Description of Voting Rights” and the “Quorum and Vote Requirements” sections below for additional information.

(4)Pursuant to the Shareholders Agreement, the Trust has agreed not to beneficially own more than the greater of 10% of the Company’s outstanding shares of Common Stock and such shares representing 22.5% of the voting rights in the Company. The Shareholders Agreement further provides for voting restrictions that require the Trust to vote (1) all shares representing voting rights in excess of 20% of the voting rights in the Company and (ii) all of its shares in connection with a change in control transaction, in each case, in a manner proportionally equal to votes of shares not beneficially owned by the Trust. Without these restrictions, the calculated Percent of Available Votes would have been 40.7% as of February 24, 2026 (record date), See the “Related Person Transactions” section above for additional information regarding the Shareholders Agreement, including the identities of joint reporting persons and additional information regarding voting rights and beneficial ownership. As of the filing of the Company's Form 10-K on February 25, 2026, and pursuant to the Shareholders Agreement, the Trust has ninety (90) days from February 25, 2026, to transfer shares it beneficially owns to move below the 10% ownership threshold of the Company's outstanding shares of Common Stock.

Pursuant to Section 16 of the Exchange Act, executive officers, Directors, and holders of more than 10% of the Common Stock are required to file reports of their trading in Company equity securities with the SEC. Based solely on a review of the copies of such reports received by the Company, or written representations from certain reporting persons, the Company believes that all filings required to be made by its reporting persons complied with all applicable Section 16 filing requirements during the last fiscal year with one exception. Due to an administrative error, Max K. Brodén, a named executive officer, did not timely report on Form 4 a grant of restricted stock on February 11, 2025 for his spouse within two business days of the transaction.

Shareholders request that the Board of Directors adopt an enduring policy, and amend the governing documents as necessary including the Corporate Governance Guidelines in order that 2 separate people hold the office of the Chairman and the office of the CEO as soon as possible.

The Chairman of the Board shall be an Independent Director. An independent Lead Director shall not be a substitute for an independent Board Chairman.

The Board shall have the discretion to select an interim Chairman of the Board, who is not an Independent Director, to serve while the Board is required to seek an Independent Chairman of the Board on an accelerated basis. This policy could be phased in when there is a contract renewal for our current CEO or for the next CEO transition although it is better to adopt it now to obtain the maximum benefit.

An independent Board Chairman at all times improves corporate governance by bringing impartiality, objective oversight, and external expertise to board decisions, mitigating conflicts of interest, enhancing transparency, and boosting shareholder confidence.

This detached perspective allows the chairman to focus on shareholder interests, strengthen management accountability, and provide critical checks and balances, ultimately contributing to long-term sustainability and credibility.

Aflac apparently does not like shareholder proposals. Aflac prevented a vote on a 2025 shareholder proposal.

Now could be a ripe time for this policy since Aflac stock performance was flat year-over-year in late 2025 despite a robust stock market.

Plus challenging news reports regarding Aflac emerged in 2025.

Aflac's first-quarter 2025 revenue of $3.4 billion was significantly below analysts' forecasts of $4.2 billion, largely due to net investment losses.

In June 2025, Aflac was one of several insurance companies targeted in a "cybercrime campaign" by a hacking group known as "Scattered Spider." The hack put customer Social Security numbers, insurance claims, and health data at risk.

Following the data breach, multiple class-action lawsuits were filed against Aflac, accusing the company of negligence, breach of contract, and invasion of privacy. The lawsuits charged that Aflac was warned about such risks for years but under-spent on digital security.

Several analyses suggested caution regarding Aflac stock, citing Aflac's high price-to-earnings ratio compared to peers and the ongoing challenges in its Japanese market.

2026 PROXY STATEMENT 81

SOLICITATION AND REVOCATION OF PROXY

This Proxy Statement is furnished to shareholders in connection with the solicitation of proxies by the Company’s Board of Directors (the “Board”), on behalf of the Company, for use at the Annual Meeting of Shareholders to be held on Monday, May 4, 2026 for the purposes set forth in the accompanying Notice of Annual Meeting and described in detail herein, and any adjournment of that meeting. The Annual Meeting will be held at 10 a.m. Eastern Time solely by means of remote communication in a virtual meeting format. Details on how to participate are available at www.virtualshareholdermeeting.com/AFL2026 and investors.aflac.com.

The mailing address of our principal executive offices is Aflac Incorporated, 1932 Wynnton Road, Columbus, Georgia 31999.

All properly executed proxies returned to the Company will be voted in accordance with the instructions contained thereon. If you return your signed proxy with no voting instructions indicated, the proxy will be voted FOR the election of all Director nominees named in this Proxy Statement, FOR approval of Proposals 2 and 3, AGAINST approval of Proposal 4, and according to the discretion of the proxy holders on any other matters that may properly come before the Annual Meeting or any postponement or adjournment thereof. If you are a shareholder of record, you also may submit your proxy online or by telephone in accordance with the procedures set forth in the enclosed proxy. Shareholders can revoke a proxy at any time before it is exercised by giving written notice to that effect to the Corporate Secretary of the Company or by submitting a later-dated proxy or subsequent internet or telephonic proxy.

This Proxy Statement and the accompanying proxy are being first delivered to shareholders on or about March 19, 2026.

Solicitation of Proxies

The Company will pay the cost of soliciting proxies. The Company will make arrangements with brokerage firms, custodians, and other fiduciaries to send proxy materials to their customers, and will reimburse these entities for the associated mailing and related expenses. In addition, certain officers and other employees of the Company may solicit proxies by telephone and by personal contacts, but those individuals will not receive additional compensation for these efforts. The Company has retained Georgeson LLC to assist in the solicitation of proxies for a fee of $10,000, plus reimbursement of reasonable out-of-pocket expenses.

Proxy Materials and Annual Report

As permitted by SEC rules, we are making these proxy materials available to our shareholders electronically. We believe providing online access to our critical documents will conserve natural resources and reduce the costs of printing and distributing our proxy materials. Accordingly, we have mailed to most of our shareholders a notice about the internet availability of this Proxy Statement and the Company’s Annual Report on Form 10-K for the year ended December 31, 2025 (“Annual Report”) instead of paper copies of those documents. The notice contains instructions on how to access our reports online, how to vote at proxyvote.com, and how to request and receive a paper copy of our proxy materials, including this Proxy Statement and our Annual Report. If you select the online access option for the Proxy Statement, Annual Report, and other account mailings, you will receive an electronic notice of availability of your proxy materials. If you do not receive a notice and did not already elect online access, you will receive a paper copy of the proxy materials by mail.

For future documents, registered shareholders may select a method of delivery by visiting https://shareholder.broadridge.com/aflac. If you own shares indirectly through a broker, bank, or other nominee, please contact your financial institution for additional information regarding delivery options.

82 AFLAC INCORPORATED SOLICITATION AND REVOCATION OF PROXY

Multiple Shareholders Sharing the Same Address

The Company is sending only one Annual Report and one Proxy Statement or notice of availability of these materials to shareholders who consented and who share a single address. This is known as “householding.” However, any registered shareholder who wishes to receive a separate Annual Report or Proxy Statement may contact Shareholder Services by phone at (706) 596-3581, by email at shareholder@aflac.com, or by mail at the address set forth above and we will promptly provide additional copies. If you receive multiple copies of the Annual Report or Proxy Statement or notice of availability of these materials, you may request householding by contacting Shareholder Services (if you are a registered shareholder) or by contacting the holder of record (if you own the Company’s shares through a bank, broker, or other holder of record).

Description of Voting Rights

The Company believes that long-term shareholders should have a greater say in our success. Accordingly, as approved by shareholders, the Company’s Articles of Incorporation provide that each share of the Company’s Common Stock is entitled to one vote (“short-term shares”) until it has been held by the same beneficial owner for a continuous period of longer than 48 months prior to the record date of the meeting, at which time each share becomes entitled to ten votes (“long-term shares”). If a share is transferred by gift, devise, or bequest, or otherwise through the laws of inheritance, descent, or distribution from the estate of the transferor, or by distribution to a beneficiary of shares held in trust, the transferee is deemed to be the same beneficial owner as the transferor for purposes of determining the number of votes per share. Shares acquired as a direct result of a stock split, stock dividend, or other distribution with respect to existing shares are deemed to have been acquired and held continuously from the date on which the underlying shares were acquired. Shares of Common Stock acquired pursuant to the exercise of a stock option are deemed to have been acquired on the date the option was granted.

The Company’s time-phased voting rights differ significantly from dual-class share structures, as neither the long-term shares nor the short-term shares (1) have a preference over the other with regard to dividends or upon liquidation, (2) carry any preemptive rights enabling a holder to subscribe for or receive shares, (3) are entitled to vote cumulatively for Directors, or (4) differ in any respect other than the additional voting rights.

The Company’s voting rights structure was approved by over 90% of our shareholders in 1985. Since that time, the Company and the Board have regularly discussed our time-phased voting rights with our shareholders, including the strategic rationale of the structure as it relates to our business relationships, and continues to believe that it is the right capital structure for the Company. The Company will remain engaged with our shareholders to hear their views on our time-phased voting rights and convey the Board’s rationale for our current voting structure, which serve to amplify the voice of long-term shareholders by providing them, regardless of affiliation or views on management or the Board, with more say by virtue of their longer financial commitment to the Company.

Shares of Common Stock held in “street” or “nominee” name are presumed to be short-term shares (held for less than 48 months) and are entitled to one vote per share unless this presumption is rebutted by evidence to the contrary. If you wish to demonstrate that you have held your Common Stock in street name for longer than 48 months, please complete and execute the affidavit appearing on the reverse side of your proxy. The Board may require evidence to support the affidavit.

Quorum and Vote Requirements

Holders of record of Common Stock at the close of business on February 24, 2026, will be entitled to vote at the Annual Meeting. At that date, the number of outstanding shares of Common Stock entitled to vote was 515,183,672. According to the Company’s records, this represents the following voting rights:

Number of shares									Votes per share						Yields this many votes
429,662,845						@			1			=			429,662,845
85,520,827						@			10			=			855,208,270
515,183,672									Total						1,284,871,115

If all of the outstanding shares were entitled to ten votes per share, the total number of possible votes would be 5,151,836,720. However, for purposes of this Proxy Statement, we assume that the total number of votes that may be cast at the Annual Meeting will be 1,284,871,115.

SOLICITATION AND REVOCATION OF PROXY 2026 PROXY STATEMENT 83

The holders of shares representing a majority of the voting rights entitled to vote at the Annual Meeting, present in person or represented by proxy, will constitute a quorum for the transaction of any business that comes before the meeting. Abstentions are counted as “shares present” for purposes of determining whether a quorum exists. A broker non-vote occurs when a nominee holding shares for a beneficial owner does not vote on a particular proposal because the nominee does not have discretionary voting power with respect to that item and has not received voting instructions from the beneficial owner. Broker non-votes are counted as “shares present” at the Annual Meeting for purposes of determining whether a quorum exists.

The following table shows the voting requirements for each proposal we expect at the Annual Meeting.

Proposal			Vote required to Pass			Effect of abstentions and broker non-votes
Uncontested election of directors			Votes cast for a nominee exceed votes cast against that nominee			Abstentions and broker non-votes are not counted as votes cast and have no effect
Advisory Say-on-Pay			Majority of the votes cast			Abstentions and broker non-votes are not counted as votes cast and have no effect
Ratification of the Independent Registered Public Accounting Firm			Majority of the votes cast			Abstentions are not counted as votes cast and have no effect. Brokers and other nominees may vote without instructions with respect to this proposal, so we do not expect broker non-votes.
Shareholder Proposal regarding an Independent Board Chairman			Majority of the votes cast			Abstentions and broker non-votes are not counted as votes cast and have no effect

If a nominee who is already serving as a Director is not re-elected at the Annual Meeting in an uncontested election, Georgia law provides that Director would continue to serve on our Board as a “holdover director.” However, our Director Resignation Policy, which is part of the Company’s Guidelines on Significant Corporate Governance Issues, provides that holdover directors must tender a resignation to our Chairman of the Board. The Corporate Governance Committee will consider such resignation and recommend to the Board whether to accept or reject it. In considering whether to accept or reject the tendered resignation, the Corporate Governance Committee will consider all factors its members deem relevant, including the stated reasons why shareholders voted against such Director, the qualifications of the Director, and whether the resignation would be in the best interests of the Company and its shareholders. The Board will formally act on the Corporate Governance Committee’s recommendation no later than ninety days following the date of the Annual Meeting at which the election occurred. The Company will, within four business days after such decision was made, publicly disclose that decision in a Form 8-K filed with the SEC, together with a full explanation of the process by which the decision was made and, if applicable, the reasons for rejecting the tendered resignation. If there were a nominee who was not already serving as a Director, and that individual was not elected at the Annual Meeting, that nominee would not become a Director or a holdover director.

In a contested election at an annual meeting of shareholders (meaning the number of nominees exceeds the number of Directors to be elected), the standard for election of Directors would be a plurality of the shares represented in person or by proxy at such meeting and entitled to vote on the election of Directors.

Effect of Not Casting a Vote

If you hold your shares in street name, it is critical that you provide voting instructions to the record owner. Your bank or broker is not permitted to vote shares you hold in street name without your instructions in the election of Directors (Proposal 1) or on the advisory vote on executive compensation (Proposal 2) and the shareholder proposal regarding an Independent Board Chairman (Proposal 4). Broker non-votes on these matters will have no effect on the outcome of the proposals. Your bank or broker may vote uninstructed shares on the ratification of the appointment of the Company’s independent registered public accounting firm (Proposal 3).

If you are a shareholder of record and you do not return your proxy card, no votes will be cast on your behalf on any item of business at the Annual Meeting.

APPENDIX A – DEFINITION OF NON-U.S. GAAP MEASURES AND RECONCILIATIONS TO CORRESPONDING U.S. GAAP MEASURES

This document includes references to the Company’s financial performance measures which are not calculated in accordance with United States generally accepted accounting principles (U.S. GAAP) (non-U.S. GAAP). The financial measures exclude items that the Company believes may obscure the underlying fundamentals and trends in insurance operations because they tend to be driven by general economic conditions and events or related to infrequent activities not directly associated with insurance operations.

Due to the size of Aflac Japan, where the functional currency is the Japanese yen, fluctuations in the yen/dollar exchange rate can have a significant effect on reported results. In periods when the Japanese yen weakens, translating Japanese yen into U.S. dollars results in fewer U.S. dollars being reported. When the Japanese yen strengthens, translating Japanese yen into U.S. dollars results in more U.S. dollars being reported. Consequently, Japanese yen weakening has the effect of suppressing current period results in relation to the comparable prior period, while Japanese yen strengthening has the effect of magnifying current period results in relation to the comparable prior period. A significant portion of the Company’s business is conducted in Japanese yen and never converted into U.S. dollars but translated into U.S. dollars for U.S. GAAP reporting purposes, which results in foreign currency impact to earnings, cash flows and book value on a U.S. GAAP basis. Management evaluates the Company’s financial performance both including and excluding the impact of foreign currency translation to monitor, respectively, cumulative currency impacts and the currency-neutral operating performance over time. The average yen/dollar exchange rate is based on the published MUFG Bank, Ltd. telegraphic transfer middle rate (TTM).

The Company defines the non-U.S. GAAP financial measures included in this document as follows:

Adjusted earnings are adjusted revenues less benefits and adjusted expenses. Adjusted earnings per share (basic or diluted) are the adjusted earnings for the period divided by the weighted average outstanding shares (basic or diluted) for the period presented. The adjustments to both revenues and expenses account for certain items that are outside of management’s control because they tend to be driven by general economic conditions and events or are related to infrequent activities not directly associated with insurance operations. Adjusted revenues are U.S. GAAP total revenues excluding adjusted net investment gains and losses. Adjusted expenses are U.S. GAAP total acquisition and operating expenses including the impact of interest from derivatives associated with notes payable but excluding any non-recurring or other items not associated with the normal course of the Company’s insurance operations and that do not reflect the Company’s underlying business performance. Management uses adjusted earnings and adjusted earnings per diluted share to evaluate the financial performance of the Company’s insurance operations on a consolidated basis and believes that a presentation of these financial measures is vitally important to an understanding of the underlying profitability drivers and trends of the Company’s insurance business. The most comparable U.S. GAAP financial measures for adjusted earnings and adjusted earnings per share (basic or diluted) are net earnings and net earnings per share, respectively.

Adjusted earnings excluding current period foreign currency impact are computed using the average foreign exchange rate for the comparable prior-year period, which eliminates fluctuations driven solely by foreign exchange rate changes. Adjusted earnings per diluted share excluding current period foreign currency impact is adjusted earnings excluding current period foreign currency impact divided by the weighted average outstanding diluted shares for the period presented. The Company considers adjusted earnings excluding current period foreign currency impact and adjusted earnings per diluted share excluding current period foreign currency impact important because a significant portion of the Company’s business is conducted in Japan and foreign exchange rates are outside management’s control; therefore, the Company believes it is important to understand the impact of translating foreign currency (primarily Japanese yen) into U.S. dollars. The most comparable U.S. GAAP financial measures for adjusted earnings excluding current period foreign currency impact and adjusted earnings per diluted share excluding current period foreign currency impact are net earnings and net earnings per share, respectively.

APPENDIX A – DEFINITION OF NON-U.S. GAAP MEASURES AND RECONCILIATIONS TO CORRESPONDING U.S. GAAP MEASURES 2026 PROXY STATEMENT 87

Adjusted net investment gains and losses are net investment gains and losses adjusted for i) amortized hedge cost/income related to foreign currency exposure management strategies and certain derivative activity, ii) net interest income/expense from foreign currency and interest rate derivatives associated with certain investment strategies, which are both reclassified to net investment income, and iii) the impact of interest from derivatives associated with notes payable, which is reclassified to interest expense as a component of total adjusted expenses. The Company considers adjusted net investment gains and losses important as it represents the remainder amount that is considered outside management’s control, while excluding the components that are within management’s control and are accordingly reclassified to net investment income and interest expense. The most comparable U.S. GAAP financial measure for adjusted net investment gains and losses is net investment gains and losses.

Amortized hedge costs/income represent costs/income incurred or recognized as a result of using foreign currency derivatives to hedge certain foreign currency exchange risks in the Company’s Japan segment or in Corporate and other. These amortized hedge costs/income are estimated at the inception of the derivatives based on the specific terms of each contract and are recognized on a straight-line basis over the contractual term of the derivative. The Company believes that amortized hedge costs/income measure the periodic currency risk management costs/income related to hedging certain foreign currency exchange risks and are an important component of net investment income. There is no comparable U.S. GAAP financial measure for amortized hedge costs/income.

Adjusted net investment income is net investment income adjusted for i) amortized hedge cost/income related to foreign currency exposure management strategies and certain derivative activity, and ii) net interest income/expense from foreign currency and interest rate derivatives associated with certain investment strategies, which are reclassified from net investment gains and losses to net investment income. The Company considers adjusted net investment income important because it provides a more comprehensive understanding of the costs and income associated with the Company’s investments and related hedging strategies. The most comparable U.S. GAAP financial measure for adjusted net investment income is net investment income.

Adjusted return on equity is annualized adjusted earnings divided by average shareholders’ equity, excluding accumulated other comprehensive income. Management uses adjusted return on equity to evaluate the financial performance of the Company’s insurance operations on a consolidated basis and believes that a presentation of this financial measure is vitally important to an understanding of the underlying profitability drivers and trends of the Company’s insurance business. The Company considers adjusted return on equity important as it excludes components of accumulated other comprehensive income, which fluctuate due to market movements that are outside management's control. The most comparable U.S. GAAP financial measure for adjusted return on equity is return on equity as determined using annualized net earnings and average total shareholders’ equity.

Adjusted return on equity excluding foreign currency remeasurement is annualized adjusted earnings divided by average shareholders’ equity, excluding both accumulated other comprehensive income and the cumulative (beginning January 1, 2021) foreign currency gains/losses associated with i) foreign currency remeasurement and ii) sales and redemptions of invested assets. The Company considers adjusted return on equity excluding foreign currency remeasurement important because it excludes both accumulated other comprehensive income and the cumulative foreign currency remeasurement gains/losses, which fluctuate due to market movements that are outside management's control. The most comparable U.S. GAAP financial measure for adjusted return on equity excluding foreign currency remeasurement is return on equity as determined using annualized net earnings and average total shareholders’ equity.

Adjusted return on equity excluding foreign currency impact is annualized adjusted earnings excluding the current period foreign currency impact divided by average shareholders’ equity, excluding accumulated other comprehensive income. The Company considers adjusted return on equity excluding foreign currency impact important as it excludes changes in foreign currency and components of accumulated other comprehensive income, which fluctuate due to market movements that are outside management’s control. The most comparable U.S. GAAP financial measure for adjusted return on equity excluding foreign currency impact is return on equity as determined using annualized net earnings and average total shareholders’ equity.

Adjusted return on equity excluding foreign currency impact [New] is annualized adjusted earnings excluding the current period foreign currency impact divided by average shareholders’ equity, excluding both accumulated other comprehensive income and the cumulative (beginning January 1, 2021) foreign currency gains/losses associated with i) foreign currency remeasurement and ii) sales and redemptions of invested assets. The Company considers adjusted return on equity excluding foreign currency impact important as it holds constant the prior period foreign exchange rate for the current period, while also excluding both accumulated other comprehensive income and the cumulative foreign currency gains/losses, which fluctuate due to market movements that are outside management's control. The most comparable U.S. GAAP financial measure for adjusted return on equity excluding foreign currency impact is return on equity as determined using annualized net earnings and average total shareholders’ equity.

Adjusted revenues excluding current period foreign currency impact are adjusted revenues calculated using the average foreign exchange rate for the comparable prior year period, which eliminates fluctuations driven solely by foreign exchange rate changes that are outside management’s control. The most comparable U.S. GAAP financial measure for adjusted revenues excluding current period foreign currency impact is total revenues.

88 AFLAC INCORPORATED APPENDIX A – DEFINITION OF NON-U.S. GAAP MEASURES AND RECONCILIATIONS TO CORRESPONDING U.S. GAAP MEASURES

Adjusted book value is the U.S. GAAP book value (representing total shareholders’ equity), less accumulated other comprehensive income as recorded on the U.S. GAAP balance sheet. Adjusted book value per common share is adjusted book value at the period end divided by the ending outstanding common shares for the period presented. The Company considers adjusted book value and adjusted book value per common share important as they exclude accumulated other comprehensive income, which fluctuates due to market movements that are outside management’s control. The most comparable U.S. GAAP financial measures for adjusted book value and adjusted book value per common share are total book value and total book value per common share, respectively.

Adjusted book value excluding foreign currency remeasurement is the U.S. GAAP book value (representing total shareholders’ equity), less accumulated other comprehensive income as recorded on the U.S. GAAP balance sheet and excluding the cumulative (beginning January 1, 2021) foreign currency gains/losses associated with i) foreign currency remeasurement and ii) sales and redemptions of invested assets. Adjusted book value excluding foreign currency remeasurement per common share is adjusted book value excluding foreign currency remeasurement at the period end divided by the ending outstanding common shares for the period presented. The Company considers adjusted book value excluding foreign currency remeasurement and adjusted book value excluding foreign currency remeasurement per common share important as they exclude both accumulated other comprehensive income and the cumulative foreign currency remeasurement gains/losses, which fluctuate due to market movements that are outside management's control. The most comparable U.S. GAAP financial measures for adjusted book value excluding foreign currency remeasurement and adjusted book value excluding foreign currency remeasurement per common share are total book value and total book value per common share, respectively.

Adjusted debt is the sum of notes payable, as recorded on the U.S. GAAP balance sheet, excluding 50% of subordinated debentures and perpetual bonds and all pre-funding of debt maturities. The Company considers adjusted debt important as it measures outstanding debt consistently with expectations of the Company’s rating agency stakeholders. The most comparable U.S. GAAP financial measure for adjusted debt is notes payable.

Adjusted debt including 50% of subordinated debentures and perpetual bonds is the sum of notes payable, as recorded on the U.S. GAAP balance sheet, excluding pre-funding of debt maturities. The Company considers adjusted debt including 50% of subordinated debentures and perpetual bonds important as it measures outstanding debt consistently with expectations of the Company’s rating agency stakeholders. The most comparable U.S. GAAP financial measure for adjusted debt including 50% of subordinated debentures and perpetual bonds is notes payable.

(1)U.S. GAAP ROE is calculated by dividing net earnings (annualized) by average shareholders’ equity.

(2)See separate reconciliation of net earnings to adjusted earnings.

(3)Impact of foreign currency is calculated by restating all foreign currency components of the income statement to the weighted average foreign currency exchange rate for the comparable prior year period. The impact is the difference of the restated adjusted earnings compared to reported adjusted earnings. For comparative purposes, only current period income is restated using the weighted average prior period exchange rate, which eliminates the foreign currency impact for the current period. This allows for equal comparison of this financial measure.

(3)Impact of gains/losses associated with foreign currency remeasurement is calculated by excluding the cumulative (beginning January 1, 2021) foreign currency gains/losses associated with i) foreign currency remeasurement and ii) sales and redemptions of invested assets. The impact is the difference of adjusted return on equity - reported compared with adjusted return on equity, excluding from shareholders' equity, gains/losses associated with foreign currency remeasurement.

(4)Impact of foreign currency is calculated by restating all foreign currency components of the income statement to the weighted average foreign currency exchange rate for the comparable prior year period.

APPENDIX B – DEFINITION OF OPERATIONAL MEASURES

The Company defines the operational measures included in this document as follows:

New annualized premium sales is sometimes referred to as new sales or sales. An operating measure that is not reflected on the Company's financial statements. New annualized premium sales generally represent annual premiums on policies and riders the Company sold and incremental increases from policy conversions that would be collected over a 12-month period assuming the policies remain in force for that entire period. For Aflac Japan, new annualized premium sales are determined by applications submitted during the reporting period. For Aflac U.S., new annualized premium sales are determined by applications that are issued during the reporting period. Policy conversions are defined as the positive difference in the annualized premium when a policy upgrades in the current reporting period. The Company believes that this metric is a key indicator of the Company's future source of earnings.

Aflac Japan’s new annualized premiums sales (as adjusted for MIP) is a measure that is calculated in Japanese yen and adjusts Aflac Japan’s new annualized premium sales to exclude new annualized premiums sales from lapse and reissue for Tsumitasu. The Company believes this metric reflects management’s expectations for Aflac Japan’s new annualized premium sales.

Total shareholder return (TSR) is a measure of financial performance that represents the percentage of total return (including both share price appreciation and dividends received) on a share of the Company’s Common Stock over a certain period. The Company believes TSR is a good gauge of the long-term value of investment for Aflac Incorporated’s shareholders.

Operating ratios are used to evaluate the Company's financial condition and profitability. Examples include: (1) Ratios to total adjusted revenues, which present expenses as percentage of total revenues and (2) Ratios to total premium, including benefit ratio. Operating ratios include: Benefit Ratio and Expense Ratio.

Premium persistency is the percentage of premiums remaining in force at the end of a period, usually one year, and presented on a trailing 12-month average basis. For example, 95% persistency would mean that 95% of the premiums in force at the beginning of a period are still in force at the end of the period. The Company believes that this metric is a key driver of in force levels, which is a key measure of the size of the Company's business and future sources of earnings.

Aflac Japan's net earned premium (as adjusted for MIP) is a measure that is calculated in Japanese yen and adjusts Aflac Japan's net earned premiums for certain variables including the change in deferred profit liability on limited payment contracts, any in-year reinsurance transactions that are not in Plan with a transaction asset threshold or a release of U.S. GAAP future policy benefit reserves threshold in excess of ¥3 billion, and earned premiums from Aflac Pet Small amount-and-Short-term Insurance Co., Ltd. that are excluded from the Company’s MIP basis. The Company believes this metric reflects management's expectations for Aflac Japan's net earned premium.
