Allstate reported estimated catastrophe losses of $220 million, or $173 million after-tax, for September. That brings the third quarter's total catastrophe losses to $1.65 billion pretax, or $1.30 billion after-tax, according to the company's monthly release dated October 15, 2026.
The September figure marks a sharp drop from August's $748 million in catastrophe losses. The pullback suggests the severe convective storm activity that drove August's spike did not continue into September.
Most of the quarter's $1.65 billion in losses still traces back to August, so the slowdown in September looks like a return to a calmer baseline rather than a shift in the underlying catastrophe trend. Allstate is due to report full third-quarter results on November 4, after market close, with a call for analysts the following morning, according to Allstate Newsroom. Investors will measure the final monthly tally against those earnings to gauge how much of the $1.65 billion cuts into underwriting margins already strained by July and August.
