Two carriers, one state, the same three-day earnings window, and two completely different stories. That's California personal auto right now, and it's worth untangling because the honest answer to "is it getting worse" turns out to be yes, no, and it depends, all at once.
Start with Kemper Corporation's second quarter, buried under a $460 million non-cash goodwill charge that ate the headline number. Strip that out and the specialty personal auto book still tells an uncomfortable story on its own: the underlying loss and LAE ratio climbed to 83.8% from 72.5% a year earlier, driven by rising claim severity and frequency specifically in California — a detail buried inside Insurance Business's latest Q2 earnings round-up.
Now put that next to Mercury General, a carrier that writes a larger share of its own book in California than any other public insurer, reporting in the same window. Mercury's combined ratio improved to 89.9% in the second quarter, down from 92.5% a year ago, part of a wildfire-reserve-driven turnaround Insurance Business covered in detail, with net income up 58.3% to $263.5 million. Some of that comparison is flattered by how bad Mercury's first half of 2025 was, when the Palisades and Eaton wildfires drove catastrophe losses to $460 million. But even on an accident-period basis, stripped of prior-year reserve noise, Mercury's first-half combined ratio improved to 91.1% from 107.2%.
So which is it? A closer look at what's actually moving under both books suggests the answer is that California auto overall is really getting better, but the segment Kemper plays in is moving in the opposite direction, and there's a specific, dateable reason that might explain why.
On January 1, 2025, California's Senate Bill 1107, the Protect California Drivers Act, took effect, doubling the state's minimum bodily injury liability limit from $15,000 to $30,000 per person and tripling the minimum property damage limit from $5,000 to $15,000. It was the state's first change to minimum limits since the 1960s and 70s, and mechanically, it does something specific to a carrier's loss costs: any policy written at the old minimum instantly carries twice or three times the potential payout per claim the moment it renews into the new limits.
That matters more for some books than others. Drivers who buy exactly the state minimum, rather than shopping for higher liability protection, skew toward the specialty and nonstandard segment of the market, the same corner Kemper's specialty personal auto unit competes in, rather than the preferred, higher-limit business that makes up more of Mercury's book. A carrier writing a lot of minimum-limit policies absorbed a mechanical, one-time jump in exposure per claim that a carrier writing mostly higher-limit policies simply didn't feel to the same degree.
Layer on top of that a broader claims trend that's hitting nearly every carrier in the state to some extent. The Insurance Research Council's most recent closed-claim study found California bodily injury and personal injury protection claim costs rose 18% in 2025, outpacing the 11% national average, with the average bodily injury payment per insured vehicle reaching $9,840, up from $8,340 the year before. That aligns with what claims-data firm CCC found nationally: bodily injury claims now account for 52.3% of combined BI and physical-damage dollars paid, up from 44.4% in 2022, even as physical-damage claim frequency has been falling, according to reporting this week on CCC's findings.
California's personal auto insurers as a group posted their strongest underwriting results in years during the first half of 2026, as rate increases approved by the California Department of Insurance under Proposition 103 finally worked their way through carrier books, following three straight years of underwriting losses that pushed several national carriers to pull back from the state between 2022 and 2024. That's the context that makes Kemper's number look like an outlier rather than a preview of where the state is headed. More than 30 personal auto rate filings were still pending CDI review as of this spring, though the pace of double-digit rate requests has noticeably slowed compared with 2024 and 2025.
The rate relief that's been working its way through the standard and preferred market since 2024 has genuinely turned the corner for carriers like Mercury. Whether it's worked its way through the specialty and nonstandard tier at the same pace, or whether SB 1107's minimum-limit mechanics hit that tier harder in the interim, is the open question Kemper's quarter raises without fully answering on its own.
Kemper isn't disputing that its California book is the problem. CEO Stephen McAnena, who ended a seven-month leadership gap when he took the permanent role on June 1 following Joseph Lacher's abrupt October 2025 departure, told analysts on the second-quarter call that personal auto isn't delivering target returns, and pointed the blame squarely at the company's California concentration.
The numbers he and CFO Bradley Camden laid out are more useful than the tone. Camden said the company got roughly 5.5% of blended rate approved and earning in during the quarter, with another 6.9% filing pending. McAnena was blunt about what that adds up to against what's actually needed: "we need double-digit rate in California" to restore profitability. Single-digit relief booked and pending, against a company that says double digits is the bar, is the lag in hard numbers rather than just inference.
Management also confirmed something the earlier section only inferred, without quite putting it in these words. Kemper just unified underwriting, pricing, product, and claims for auto under one new P&C leader, Eric Kappler, whom McAnena described as bringing deep experience in non-standard auto, and welcomed a new board member, Tony DeSantis, who spent a decade in the same niche. That's Kemper's own leadership using the same non-standard-auto framing laid out above.
Kemper is also actively shrinking its way out of the state rather than just waiting on rate. California's share of the personal auto book fell 2.5 percentage points during the quarter as policies in force there dropped 10% sequentially, which management framed as a deliberate non-rate action rather than attrition the company is fighting. One analyst on the call noted that Kemper's personal-auto policy count nationally has fallen from more than 2 million before the pandemic to roughly 928,000 today; nobody on the call disputed the figure.
There's a genuinely encouraging number buried in the sequential trend, too. Personal auto's underlying combined ratio improved from 106.5% in the first quarter of 2026 to 105.2% in the second, and California's combined ratio ticked down quarter over quarter as well, something Camden called a positive sign given that ratios typically rise, not fall, moving from Q1 into Q2 on seasonality alone. Year over year, the book is still worse than it was a year ago. Quarter over quarter, inside 2026 itself, it's already bending the other way.
For agents and brokers with nonstandard or minimum-limit-heavy California auto business, Kemper's quarter is worth treating as a bellwether with an asterisk. The year-over-year numbers say the specialty tier is still lagging the broader market's rate-driven recovery, and Kemper's own math shows the rate it's gotten so far falls short of what it says it needs. But the company is already pulling back from the state on purpose, and its own sequential numbers, quarter over quarter within 2026, are already improving. The more useful signal for brokers than "getting worse" or "getting better" may simply be "still adjusting," with the CDI's response to that pending 6.9% filing as the next concrete date worth watching.
