ITEM 1. BUSINESS

Insurance Products

Aflac Japan's third sector insurance products are supplemental products designed to help consumers pay for medical and nonmedical costs that are not reimbursed under Japan's national health insurance system. Changes in Japan's economy and an aging population have put increasing pressure on Japan's national health care system. As a result, more costs have been shifted to Japanese consumers, who in turn have become increasingly interested in insurance products that help them manage those costs. Aflac Japan has responded to this consumer need by enhancing existing products and developing new products. Aflac Japan remains focused on maintaining leadership in third sector insurance products that are less interest rate sensitive and have strong and stable margins. At the same time, Aflac Japan complements this core business with similarly profitable first sector products as outlined below.

Distribution Channels

Traditional Sales Channel This distribution channel includes individual agencies, independent corporate agencies and affiliated corporate agencies. Aflac Japan was represented by approximately 6,300 sales agencies at the end of 2025, with approximately 112,000 licensed sales associates employed by those agencies, including individual agencies.Dai-ichi Life Aflac Japan's alliance with Dai-ichi Life was launched in 2001, and approximately 37,000 Dai-ichi Life representatives offer Aflac Japan's cancer products. Dai-ichi Life is included in Aflac Japan's affiliated corporate agencies distribution channel.Japan Post Group Aflac Japan's alliance with Japan Post Group, which is included in Aflac Japan's affiliated corporate agencies distribution channel, was launched in 2008. After the alliance strengthened in 2013, the number of postal outlets of Japan Post Co. Ltd. (Japan Post Co.) offering Aflac Japan's cancer product increased, with approximately 20,000 postal outlets as of December 31, 2025. Japan Post Insurance Co., Ltd. (Japan Post Insurance) offers Aflac Japan's cancer products through its 76 branches responsible for corporate sales and 626 service departments in charge of individual sales.Daido Life Aflac Japan's alliance with Daido Life was launched in 2013, and approximately 3,700 Daido Life representatives offer Aflac Japan's cancer products to mainly small and medium-sized business owners, executives and employees. Daido Life is included in Aflac Japan's affiliated corporate agencies distribution channel.Banks Consumers in Japan rely on banks to provide not only traditional bank services, but also as one key source to provide insurance solutions and other services. At December 31, 2025, Aflac Japan had agreements with approximately 90% of the total number of banks in Japan to sell its products.

Competitive Markets

The Company competes with other insurance carriers through product design, price, policyholder service, and sales efforts. Since the deregulation of the Japan market in 2001, the number of insurance companies offering stand-alone cancer and medical insurance has increased, intensifying competition. However, based on Aflac Japan's size of annualized premiums in force and diversified distribution network, the Company believes it is well-positioned to continue to adapt to increased competition. Furthermore, the Company believes the continued development and maintenance of operating efficiencies will allow Aflac Japan to offer affordable products that appeal to consumers. The Company believes Aflac Japan will remain a leading provider of third sector products such as cancer and medical insurance coverage in Japan, principally due to its experience in the market, well-known brand, low-cost operations, expansive marketing system and product expertise.

Government Regulation

Financial Services Agency (FSA) The financial and business affairs of Aflac Japan are subject to examination by Japan's FSA. Aflac Japan files annual and interim reports and financial statements for the Japanese insurance operations based on a March 31 fiscal year-end, prepared in accordance with Japanese regulatory accounting practices prescribed or permitted by the FSA. Japanese regulatory basis earnings are determined using accounting principles that differ materially from U.S. generally accepted accounting principles (U.S. GAAP).

Aflac Japan's SMR is sensitive to interest rate, credit spread and foreign exchange rate changes. See the Liquidity and Capital Resources section of Item 7. MD&A for additional information on SMR, including a discussion of measures the Company has taken to mitigate the sensitivity of Aflac Japan's SMR and the introduction of an economic value-based solvency regime based on the Insurance Capital Standards (ICS) for insurance companies effective for Aflac Japan's 2025 fiscal year-end.Companies Act of Japan Aflac Japan dividend distributions to the Parent Company are subject to permitted dividend capacity under the Companies Act of Japan.

Seasonality

In recent years, new annualized premium sales are generally higher in the fourth quarter for Aflac U.S. group business due to the timing of open enrollment for many employers. As a result, a significant portion of total new annualized premium sales for Aflac U.S. group business are generated in the fourth quarter, which typically results in over one third of Aflac U.S. total sales being generated in the fourth quarter.

Distribution Channels

Independent Associates/Career Agents The career agent channel in Aflac U.S. focuses on marketing Aflac to the small business market, defined as employers of between three and 99 employees. Sales associates in the U.S. are independent contractors and are paid commissions and other variable compensation based on first-year and renewal premiums from their sales of insurance products. Brokers The broker channel of Aflac U.S. focuses on selling to the mid- and large-case market, which is comprised of employers with 100 or more employees and typically an average size of 1,000 employees or more. Brokers in the U.S. are independent contractors and are paid commissions and other variable compensation based on first-year and renewal premiums from their sales of insurance products.In 2025, the Aflac U.S. sales force included an average of approximately 5,300 U.S. agents, including brokers, who were actively producing business on a weekly basis. For additional information, see the Aflac U.S. Segment subsection of Item 7. MD&A.Consumer Markets While Aflac U.S. primarily markets its insurance products at the worksite, Aflac U.S. is also expanding its distribution strategy to directly reach consumers outside of the traditional worksite through digital lead generation.

Competitive Markets

Aflac U.S. competes against several supplemental insurance carriers on a national and regional basis. Aflac U.S. believes its policies, premium rates, platforms, value-added services and sales commissions are competitive by product type. Moreover, Aflac U.S. believes that its products are distinct from competitive offerings given its product focus (including features, benefits and claims service model), distribution capabilities and brand awareness. Since Aflac products provide an additional level of financial protection for policyholders, the Company believes the increased financial exposure some employees may face creates a favorable opportunity for Aflac U.S. products. However, given the profitability erosion some major medical carriers are facing in their core lines of business, the Company has seen a more competitive landscape as these carriers seek entry into Aflac's supplemental product segments and leverage their core benefit offerings by bundling and discounting products in order to gain market share.

Government Regulation

State Insurance Regulation The Parent Company and its U.S. insurance subsidiaries, Aflac, CAIC, TOIC (Nebraska-domiciled insurance companies), Aflac New York (a New York-domiciled insurance company) and ABS (a licensed third-party administrator in most U.S. jurisdictions and a pre-paid limited health service organization in Florida) are subject to state regulations in the U.S. as an insurance holding company system. Such regulations generally provide that certain transactions between companies within the holding company system must be fair and equitable. In addition, transfers of assets among such affiliated companies, certain dividend payments from insurance subsidiaries and certain transactions between companies within the system, including management fees, loans and advances are subject to prior notice to, or approval by, state regulatory authorities. These laws generally require, among other things, the insurance holding company and each insurance company directly owned by the holding company to register with the insurance departments of their respective domiciliary states and to furnish annually financial and other information about the operations of companies within the holding company system.Like all U.S. insurance companies, Aflac, CAIC, TOIC and Aflac New York are subject to regulation and supervision in the jurisdictions in which they do business. In general, the insurance laws of the various jurisdictions establish supervisory agencies with broad administrative powers relating to, among other things:•granting and revoking licenses to transact business•regulating trade and claims practices•licensing of insurance agents and brokers•approval of policy forms and premium rates•standards of solvency and maintenance of specified policy benefit reserves and minimum loss ratio requirements•capital requirements•limitations on dividends to shareholders•the nature of and limitations on investments•deposits of securities for the benefit of policyholders•filing of financial statements prepared in accordance with statutory insurance accounting practices prescribed or permitted by regulatory authorities•periodic examinations of the market conduct, financial, and other affairs of insurance companiesThe insurance laws of Nebraska that govern the Company's activities provide that the acquisition or change of “control” of a domestic insurer or of any person that controls a domestic insurer cannot be consummated without the prior approval of the Nebraska Department of Insurance (NDOI). A person seeking to acquire control, directly or indirectly, of a domestic insurance company or of any person controlling a domestic insurance company (in the case of Aflac, CAIC and TOIC, the Parent Company) must generally file with the NDOI an application for change of control containing certain information required by statute and published regulations and provide a copy to the Company. In Nebraska, control is generally presumed to exist if any person, directly or indirectly, acquires 10% or more of an insurance company or of any other person or entity controlling the insurance company. The 10% presumption is not conclusive and control may be found to exist at less than 10%. Similar laws apply in New York, the domiciliary jurisdiction of Aflac's New York insurance subsidiary.State insurance departments conduct periodic examinations of the books and records, financial reporting, policy filings and market conduct of insurance companies domiciled in their states, generally once every three to five years. Examinations are generally carried out in cooperation with the insurance departments of other states under guidelines promulgated by the National Association of Insurance Commissioners (NAIC). Beginning in 2024 and concluding in 2025, the NDOI and the New York State Department of Financial Services (NYSDFS) conducted full-scope, risk-focused financial examinations on their respective state domiciled insurance entities covering the reporting period January 1, 2020 – December 31, 2023. Additionally, beginning in 2023 and concluding in 2025, the NYSDFS conducted a routine market conduct examination on Aflac New York covering the five-year period ended on December 31, 2022. There were no material findings in any of the NDOI and NYSDFS final examination reports.NAIC Risk-Based Capital The NAIC continually reviews regulatory matters, such as risk-based capital (RBC) modernization, group capital calculations and liquidity risk assessment. The NAIC uses an RBC formula relating to insurance risk, business risk, asset risk and interest rate risk to facilitate identification by insurance regulators of inadequately capitalized insurance companies based upon the types and mix of risk inherent in the insurer's operations. The formulas for determining the amount of RBC specify various weighting factors that are applied to financial balances or various levels of activity based on the perceived degree of risk. Regulatory compliance is determined by a ratio of a company's regulatory total adjusted capital to its authorized control level RBC as defined by the NAIC. Companies below specific trigger points or ratios are classified within certain levels, each of which requires specified corrective action. The levels are company action, regulatory action, authorized control, and mandatory control. See Note 14 of the Notes to the Consolidated Financial Statements and the Liquidity and Capital Resources section of Item 7. MD&A for additional information on RBC.Guaranty Association and Similar Arrangements Under state insurance guaranty association laws and similar laws in international jurisdictions, the Company is subject to assessments, based on the share of business the Company writes in the relevant jurisdiction, for certain obligations of insolvent insurance companies to policyholders and claimants. In the U.S., some states permit member insurers to recover assessments paid through full or partial premium tax offsets. The Company's policy is to accrue assessments when the entity for which the insolvency relates has met its state of domicile's statutory definition of insolvency, the amount of the loss is reasonably estimable and the related premium upon which the assessment is based is written. In most states, the definition is met with a declaration of financial insolvency by a court of competent jurisdiction. Federal and State Regulation Federal and state legislation and regulations in several areas, including health care reform legislation, financial services reform legislation, securities regulation, pension regulation, privacy, anti-money laundering, tort reform legislation and taxation, can significantly and adversely affect insurance companies. Certain federal and state laws and regulations applicable to Aflac U.S. are outlined below.

•Patient Protection and Affordable Care Act

The Patient Protection and Affordable Care Act and the Health Care and Education Reconciliation Act of 2010 (collectively, the ACA), federal health care reform legislation, gave the U.S. federal government direct regulatory authority over the business of health insurance. The ACA, as enacted, does not require material changes in the design of the Company's insurance products. However, indirect consequences of, or changes to, the legislation and regulations could present challenges that could potentially have an impact on the Company's sales model, financial condition and results of operations. Certain provisions of the ACA have been and may continue to be subject to challenge through litigation, the ultimate effects of which on the ACA are uncertain. See Item 1A. Risk Factors for the risk factor entitled, "Extensive regulation and changes in legislation can impact profitability and growth" for additional information.

•Dodd-Frank Act

Title VII of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (Dodd-Frank) and regulations issued thereunder, in particular rules to require central clearing for certain types of derivatives, may have an impact on the Company's derivative activity, including activity on behalf of Aflac Japan. The Dodd-Frank Act also established a Federal Insurance Office (FIO) under the U.S. Department of the Treasury to monitor all aspects of the insurance industry and of lines of business other than certain health insurance, certain long-term care insurance and crop insurance.

•Privacy and Cybersecurity

In the absence of a comprehensive federal privacy law, states are making a push towards privacy legislation. Personally identifiable information is used in support of many of the Company's business processes. For many years, the standard for protection and treatment of that data was benchmarked by privacy and security provisions of the federal Gramm-Leach-Bliley Act of 1999 (GLBA) and in the Health Insurance Portability and Accountability Act of 1996 (HIPAA). As consumers have grown more concerned about the protection of their data, as well as how their data is used by organizations, jurisdictions within and outside of the U.S. have created legislation and issued regulations that apply or may in the future apply to aspects of Aflac U.S. operations and allow consumers the right to access, correct, delete, or opt out of the sale or share, or limit the use of their data. Although not all apply to Aflac U.S. operations, an example of these state privacy laws is the California Consumer Privacy Act. Businesses across industries have also seen an increase in lawsuits alleging tracking technologies on their websites violate state or federal wiretapping laws. At the federal level, the Telephone Consumer Protection Act (TCPA) continues to provide plaintiffs with a private right of action for claims alleging violation of the TCPA. Additionally, certain states are adopting the NAIC Model Bulletin on the Use of Artificial Intelligence Systems by Insurers and, in limited cases, passing their own laws related to artificial intelligence.Cybersecurity continues to be an area of evolving focus for legislation and regulatory activity. The NYSDFS Cybersecurity Requirements for Financial Services Companies applies to Aflac New York. This regulation requires, among other things, risk assessments, administrative and technical controls, incident reporting procedures, business continuity plans, and certain cybersecurity governance, such as the designation of a Chief Information Security Officer and senior governing body oversight. In addition, more than 25 states have adopted the NAIC’s Insurance Data Security Model Law, which requires similar cybersecurity measures. For information regarding the Company's cybersecurity risk management, strategy, and governance, see Item 1C. Cybersecurity.For additional information regarding Aflac U.S. operations and regulations, see the Aflac U.S. Segment subsection of Item 7. MD&A and Notes 2 and 14 of the Notes to the Consolidated Financial Statements.
