NORTHBROOK, Ill., September 18, 2025 – The Allstate Corporation (NYSE: ALL) today announced estimated catastrophe losses for the month of August of $213 million or $168 million, after-tax. Catastrophe losses for August include 10 events with approximately 70% of the losses related to three wind and hail events. Total catastrophe losses for July and August were $397 million or $313 million, after-tax.

Allstate Protection policies in force are as follows:

(1)Policy counts are based on items rather than customers. A multi-car customer would generate multiple item (policy) counts, even if all cars were insured under one policy. Lender-placed policies are excluded from policy counts because relationships are with the lenders.

This news release contains “forward-looking statements” that anticipate results based on our estimates, assumptions and plans that are subject to uncertainty. These statements are made subject to the safe-harbor provisions of the Private Securities Litigation Reform Act of 1995.

We believe these statements are based on reasonable estimates, assumptions and plans. However, if the estimates, assumptions or plans underlying the forward-looking statements prove inaccurate or if other risks or uncertainties arise, actual results could differ materially from those communicated in these forward-looking statements.
