Aflac's net income rose 37.7% as revenue fell 1.0%. That is the odd arithmetic in the latest three-month period: $825.0 million of profit on $4.1 billion of revenue, compared with $599.0 million on $4.2 billion a year earlier.
The per-share number moved even faster. Diluted EPS rose 46.8%, helped by a 6.1% decline in diluted shares to 505.6 million. The business generated more reported profit, but the denominator also got smaller. Insurance math rarely misses a chance to add a footnote.
Aflac's net margin rose to 20.0% from 14.4%. The company says the main operating improvement came through claims: the benefits-to-premiums ratio fell to 64.0% from 66.5%.
Aflac attributes that decline to lower benefits, the effect of annual cash-flow assumption updates made in the third quarter of 2025, and higher reserve remeasurement gains.
"For the three- and six-month periods ended June 30, 2026, the total benefits and claims to total premiums ratio decreased primarily due to lower benefits reflecting the impact of annual cash flow assumption updates performed in the third quarter of 2025 and higher reserve remeasurement gains."

That is a meaningful change in the claims ratio, but it is not the same thing as broad-based revenue growth. New annualized premium sales in Aflac U.S. rose 2.6%, mainly from group products, while total revenue still edged lower.
There is another split inside the filing. Management says pretax adjusted earnings decreased because investment income was lower, interest expense was higher, and reinsurance-related impacts weighed on the result.
"Pretax adjusted earnings decreased primarily due to lower adjusted net investment income, higher interest expense, and reinsurance-related impacts."

So reported net income improved sharply while the company's adjusted earnings discussion points in the other direction. The gap matters because it separates the period's lower benefits and reserve effects from the factors management identifies in investment income, financing costs, and reinsurance.
The balance sheet adds one more unresolved detail: cash fell 12.1% to $6.1 billion. Aflac does not say why in the supplied comparison, so the cash change is an observation rather than an explanation for the earnings jump.
Aflac's annual record makes the rebound less linear. Revenue was $17.2 billion in 2025, down 9.3% from the prior year, while annual net margin fell to 21.2% from 28.8%. The current period's margin recovery sits inside a business whose recent top line has not moved in a straight line.
The latest close was $126.64 on Aug. 6, up 0.9% that day. The next 10-Q's pretax adjusted earnings bridge, particularly adjusted net investment income and interest expense, is the factual disclosure that would clarify how much of this period's profit improvement carried through the underlying earnings line.
Aflac's trade-off is plain: a smaller top line, a lower benefits ratio, and fewer shares to divide it across.
