Aflac Benefit Ratio Falls to 40.7%

Aflac's US supplemental health benefit ratio dropped 490 basis points in the third quarter, driven by a favorable actuarial review.

Updated on Nov. 5, 2026 in Insurance

Aflac's benefit ratio for its US supplemental health operations fell to 40.7% in the third quarter of 2026, down 490 basis points from 45.6% a year earlier. The company also revised its full-year US benefit ratio guidance below the 48% to 52% range it set at the start of the year.

Why it matters

The decline reflects a reserve release after Aflac's annual actuarial assumption review, which flows directly through the benefit ratio when assumptions move favorably. Employers cutting primary health plan benefits and shifting costs to employees can generate more supplemental claims, making the ratio's movement a key indicator for insurers in this market.

The figures are company-reported results from Aflac's Q3 2026 earnings, with the comparator being the same quarter a year earlier. Reserve remeasurement gains of $453 million across operations contributed to the period, and the revised full-year benefit ratio guidance was not quantified in the source.

The players

Aflac

Aflac is a major American supplemental health and insurance company known for its voluntary coverage sold through employers.

The details

Aflac's US benefit ratio climbed 220 basis points in the second quarter on a surge in group disability claims, then dropped sharply in the third quarter following a scheduled actuarial review. Premium persistency in the US segment rose 70 basis points year over year to 79.7%, while US new annualized premium sales grew 3.5% to $403 million and net earned premiums rose 3.3% to $1.5 billion.

Start of 2026: Aflac set original full-year US benefit ratio guidance of 48% to 52%.
Q2 2026: The US benefit ratio spiked to 49.5% on group disability claims.
Q3 2026: The US benefit ratio fell to 40.7% after the scheduled actuarial review.
November 5, 2026: Reporting on the Q3 2026 results was published.

Market Landscape

As employers cut primary health plan benefits and shift costs onto workers, demand for supplemental coverage becomes a larger share of insurer claims. Aflac's US results this quarter show how sharply that claims pressure can swing from one period to the next.

Premium persistency and sales trends in supplemental health coverage shape what policies cost and how many workers are offered voluntary benefits. Employees whose employers reduce primary health coverage may see more supplemental options offered at work.

The takeaway

Watch whether an insurer's benefit ratio moves are driven by one-time actuarial adjustments or sustained claims trends before judging its underlying health. Comparing quarterly ratios with full-year guidance helps separate the two.
