Allstate Q1 2026: Anatomy of a 15-Point Combined Ratio Swing

Allstate's property-liability combined ratio improved from 97.4 in Q1 2025 to 82.0 in Q1 2026, a 15.4-point swing that took net income to common shareholders from $566 million to $2.4 billion on revenue of $16.9 billion.

The underlying combined ratio improved 2.8 points. Most of the rest came from two sources that are measurable, disclosed and finite: $838 million of favorable auto reserve development, and catastrophe losses 43.7% below the prior-year quarter.

Key Takeaways

• $838 million of favorable prior-year auto development reduced the auto combined ratio by 8.8 points, against an underlying auto improvement of 1.7 points from 91.2 to 89.5.
• Homeowners swung from a $451 million underwriting loss to $685 million of income, 28.8 recorded points, while its underlying combined ratio moved 1.9 points from 62.4 to 60.5.
• The releases came from accident years 2023 and 2024, settling at 95.4% and 90.0%, where aggressive rate action against post-pandemic loss cost inflation left conservatism in the initial picks.
• Progressive's combined ratio was essentially flat year over year at 86.4 while growing policies in force 9%, so the swing is Q1 2025 having been unusually bad rather than Q1 2026 being unrepeatable.
• AM Best projects a 96.9% industry combined ratio for 2026 against 95.0% in 2025, with S&P Global expecting auto to edge up to 97.1.

Where the 15.4 Points Came From

The recorded improvement decomposes cleanly, and the components have different half-lives.

Component	Q1 2025	Q1 2026	Change	Contribution to CR Swing
Underlying Combined Ratio	83.1	80.3	-2.8 pts	Structural improvement
Catastrophe Losses (P-L)	$2.20B	$1.24B	-43.7%	~6.5 pts favorable
Prior-Year Reserve Releases (Auto)	Minimal	$838M	+$838M	~5.7 pts favorable
Earned Premium Growth	Base	+5.5%	+5.5%	Denominator expansion

Reserve releases contributed roughly 8.8 points to the auto combined ratio on their own. The catastrophe decline supplied another large block, concentrated in homeowners. Earned premium growth of 5.5%, reflecting rate written through 2024 and 2025 now reaching the earned line, expanded the denominator every loss is measured against.

Auto recorded 81.9, improving 9.4 points from 91.3. The underlying auto combined ratio went from 91.2 to 89.5, a 1.7-point improvement, so 7.7 of the 9.4 recorded points came from the $838 million of favorable prior-year development. That development sits in accident years 2023 and 2024, which settled at 95.4% and 90.0%.

Homeowners produced the larger absolute swing, from a $451 million underwriting loss to $685 million of underwriting income, a 28.8-point move from 112.3 to 83.5. Catastrophe losses in that book fell from $1.82 billion to $1.05 billion, a $778 million decline. The underlying homeowners combined ratio moved 1.9 points, from 62.4 to 60.5, on average gross written premium up 6.8% and average earned premium up 5.7%.

Two Numbers Doing the Work

The reason to separate recorded from underlying here is that both of the large contributors are drawn from stocks rather than flows.

The reserve release is the first. Allstate took aggressive rate action through 2023 and 2024 against post-pandemic loss cost inflation, and the initial loss picks for those years carried uncertainty margins reflecting severity trend and social inflation concerns. As claims matured and closed, that conservatism surfaced as favorable development.

The mechanism is sound and the quantity is bounded: $838 million released in one quarter is a recognition of margin that was set aside once. Whether AY 2025 and AY 2026 carry a comparable cushion determines whether the recorded auto combined ratio stays near 81.9 or reverts toward the underlying 89.5, and management's language on continuing provision for uncertainty in current accident year IBNR is a description of intent rather than a measured margin.

The catastrophe comparison is the second and it is weather. The recorded homeowners combined ratio moved 28.8 points while the underlying moved 1.9. The gap between those two movements is entirely the difference between a heavy Q1 2025 convective storm season and a lighter one this year. Q1 2026 catastrophe losses of $1.24 billion were 43.7% below the $2.20 billion of Q1 2025, and $925 million of that arrived in March across fifteen wind and hail events, three of which produced roughly 80% of the month.

The peer set settles which company this is about. Progressive posted 86.4, essentially flat year over year, while growing policies in force 9%; GEICO has run in the low 80s for several quarters; Travelers improved without drama. All four are profitable in personal auto because industry rate action in 2023 and 2024 restored margins. Allstate's 15.4-point swing is the size it is because Q1 2025 was unusually bad, not because Q1 2026 is exceptional.

The Cushion Is Real and It Is Priced Against Weather

The complication is that the strongest number in the release is the one most exposed to a variable Allstate does not control.

A 60.5 underlying homeowners combined ratio means roughly 40 cents of every homeowners premium dollar is retained as underwriting profit before investment income once catastrophes are stripped out. That is a genuine cushion. It is also the exact quantity that catastrophe normalization consumes: at a 10-year average catastrophe load, the recorded homeowners combined ratio settles in the mid-90s rather than the sub-85 reported here.

Allstate is adding to that exposure while it holds. Homeowners policies in force grew 2.5% to 7.74 million, roughly 190,000 additional policies, with market share expanded in 41 states representing 83% of the market. Each one carries full severe convective storm, wildfire and winter storm tail, and average earned premium growth of 5.7% is being written into a book whose quarterly result already swings by hundreds of millions on weather alone.

The premium side is turning at the same time. Auto earned premium grew 2.1% while written premium was essentially flat, which is the earn-through of prior rate ending rather than continuing, and market share gains in 29 states representing 57% of auto premium alongside flat written premium implies net rate decreases in some of them. S&P Global describes private auto as having "accelerated competitive dynamics, with rate decreases matching rate increases and increased advertising spending."

The external forecasts point the same way on direction and disagree only on distance. AM Best projects a 96.9% industry combined ratio for 2026 against an estimated 95.0% for 2025, with net premium growth slowing to 4.0%; S&P Global has auto edging to 97.1; Fitch, having recorded the strongest industry underwriting in two decades in 2025 at a 93.0% combined ratio, projects 96% to 97% for 2026.

Allstate's 82.0 sits 14 to 15 points below those. The trailing 12-month adjusted return on equity of 44.4%, roughly triple a typical P&C target of 12% to 15%, is what the convergence of a one-time release, a light catastrophe quarter and an earn-through tailwind looks like when all three land in the same three months.
