8-K Impact 6/10 8-K

$ALL · ALLSTATE CORP

October 15, 2026 · AI-analyzed SEC filing

Allstate filed an 8-K under Regulation FD disclosing its September 2026 monthly catastrophe loss estimate. September losses totaled $220 million pre-tax ($173 million after-tax), bringing third-quarter 2026 catastrophe losses to $1.65 billion pre-tax ($1.30 billion after-tax). The release was furnished as Exhibit 99 and is not deemed "filed" under SEC rules.

Extended-hours trading shows ALL at $240.02, up 1.63% from the regular close of $236.17, suggesting the market had already priced in elevated catastrophe losses for the quarter and the $220M September figure was not worse than feared.

A $1.65B quarterly catastrophe loss for a $60.8B market-cap insurer is a material earnings event that directly impacts underwriting profitability and sets expectations heading into the full Q3 report.

Allstate's $1.65B Q3 catastrophe loss figure lands in a period of elevated industry-wide cat claims from hurricanes and severe convective storms, with peers like Progressive and Travelers facing similar exposure.

Catastrophe losses remain elevated at $1.65B for Q3 2026, concentrated in a single quarter, which could pressure underwriting margins and earnings. Forward-looking statements caution that actual results may differ materially from estimates.
