AFLAC (AFL) concentration risks

Aflac's single disclosed concentration is geographic: Aflac Japan's adjusted revenues accounted for 53% of the company's total adjusted revenues in 2025 — a large share that makes the Japan franchise the majority revenue contributor to the consolidated business. By disclosed size this is a high-share structural exposure, reflecting where the company's insurance penetration, distribution network, and policyholder base are most deeply rooted. It is structural rather than a contractual dependency that could be withdrawn: the Japan business represents decades of market presence with a large in-force block of supplemental health policies. The primary risk channels flowing from this concentration are currency-related and macroeconomic. Because Japan revenues are earned in yen and translated into dollars for reporting, yen/dollar movements directly affect reported adjusted revenues, premium income, and earnings even when the underlying Japan business performs steadily. A sustained yen depreciation, as has been observed in recent years, compresses the dollar-equivalent value of Japan's contribution despite local-currency stability. Beyond currency, the Japan business is sensitive to Japanese regulatory changes, demographics, and policyholder persistency trends. There is no separately disclosed customer, product, supplier, or secondary geographic concentration layered on top of the Japan exposure. The disclosed profile is therefore simple and well-understood: a single, large, structural geographic concentration where the relevant variables to monitor are the yen exchange rate, Japanese regulatory posture toward supplemental insurance, and in-force policy persistency in the Japan portfolio.
