Aflac Flags Investment Challenges and Second Cybersecurity Incident in 10-Q Filing
The insurance giant disclosed limited availability of yen-denominated investments and a new cyber breach in Japan while reporting improved earnings.
Investment Portfolio Constraints Emerge
Aflac Incorporated disclosed significant concerns about its investment portfolio concentration in its latest quarterly filing, citing "limited availability of acceptable Japanese yen-denominated investments" as a material risk factor (10-Q filing, 2026-08-07). The warning underscores challenges facing the $63 billion insurer, which generates substantial business through its Aflac Japan subsidiary.
The company also flagged "differing interpretations applied to investment valuations" and "significant valuation judgments in determination of expected credit losses" as key uncertainties affecting its portfolio management (10-Q filing, 2026-08-07).
Second Cyber Incident in Fourteen Months
Aflac revealed that on June 25, 2026, Aflac Japan detected unauthorized third-party access to certain systems, marking the second cyber incident in just over a year (10-Q filing, 2026-08-07). The company "promptly took steps designed to contain the incident and prevent further access, including suspending certain systems," though it noted "there was no indication of ransomware" (10-Q filing, 2026-08-07).
This follows a previously disclosed June 2025 incident involving unauthorized access to U.S. systems. For the earlier breach, Aflac stated it "does not believe that the June 2025 U.S. Cyber Incident is reasonably likely to have a material impact on the Company's financial condition," though it acknowledged the "potential amount of loss cannot be reasonably estimated" (10-Q filing, 2026-08-07).

Earnings Beat Despite Investment Headwinds
Despite portfolio challenges, Aflac reported second-quarter net earnings of $825 million, or $1.63 per diluted share, compared with $599 million, or $1.11 per share, in the prior-year period (10-Q filing, 2026-08-07). The improvement came as net investment losses narrowed to $153 million from $421 million a year earlier.
For the six-month period, net earnings reached $1.8 billion, or $3.61 per diluted share, versus $628 million, or $1.16 per share, in 2025 (10-Q filing, 2026-08-07). The company attributed much of the year-over-year improvement to reduced investment losses, which totaled $104 million compared to $1.4 billion in the first half of 2025.
Adjusted earnings—a non-GAAP measure—came in at $883 million, or $1.75 per diluted share, for the second quarter, slightly below the $957 million, or $1.78 per share, reported a year earlier (10-Q filing, 2026-08-07).
Currency and Capital Management
The weakening yen negatively impacted results, with the average yen/dollar exchange rate of 159.45 for the quarter representing a 9.3% decline from 144.60 in the prior year (10-Q filing, 2026-08-07). This currency movement reduced adjusted earnings per diluted share by $0.05.
Aflac continued aggressive capital returns, repurchasing $2.0 billion, or 17.5 million shares, during the first six months of 2026 (10-Q filing, 2026-08-07). The company has 96.8 million shares remaining under its buyback authorization.
Shareholders' equity stood at $30.3 billion, or $60.35 per share, at June 30, 2026, compared with $29.5 billion at year-end 2025 (10-Q filing, 2026-08-07). MarginX data indicates a quarterly dividend of $0.61 is scheduled for August 19, 2026.
