Kinsale Capital Group (KNSL) Q3 2026 earnings review
Kinsale policy sales keep falling, and casualty growth nearly stops
Kinsale Capital Group, a specialty insurer for hard-to-place commercial risks, saw revenue from active policies slow toward its shrinking sales book. Gross written premiums fell 5% from a year ago while net earned premiums grew just 3%, down from 9% last quarter. Chief executive Michael P. Kehoe pointed to underwriting discipline, and higher investment income plus share buybacks lifted operating profit per share by 9%.
| Gross written premiums | $462.9M -4.8% from a year ago |
|---|---|
| Net earned premiums | $423.5M +3.0% from a year ago |
| Profit per share, excluding one-offs | $5.70 +9.4% from a year ago |
| Combined ratio | 75.4% 74.9% a year ago |
⚖️ Verdict: 🔴 Bearish
The story got worse because the growth slowdown spread to casualty policies and caught up with earned revenue. Casualty policy sales grew less than 1% as Kinsale wrote smaller accounts, and the boost from keeping more policies away from reinsurers faded. On the brighter side, rising cash reserves lifted investment income by 18%.
The question now is whether rising policy counts and new products can restart growth once property rates settle, or if competition will keep total premiums shrinking. If new accounts win out, casualty growth rebounds; if rivals keep undercutting prices, earned revenue turns flat. Fourth-quarter policy sales and the division table in the quarterly filing will show which side is right.
🐂 Bull Case
Investment Income Grew 17.5% on a Larger Float
Kinsale invests the cash it holds between collecting policy premiums and paying out claims, a pool of money known in insurance as float. By our math, that float grew 15.9% from a year ago to $3.52 billion. Total cash and invested assets reached $5.49 billion at the end of September, up from $5.19 billion at the end of 2025.
Because the specialty insurer put new operating cash flow into bonds with higher yields, net investment income rose 17.5% from a year ago to $58.3 million. The portfolio earned an annualized gross return of 4.4% over the first nine months of 2026, and the company extended the average maturity of its bond holdings to 4.4 years.
What to watch: quarterly additions to float and cash flow from operations in the third-quarter filing. If shrinking policy sales eventually slow the inflow of new cash, investment income growth will cool down too.
Buybacks Turned 6% Operating Profit Growth Into 9% Per Share
Operating profit, which excludes stock market swings and bond sale losses, grew 5.9% from a year ago to $128.3 million. Per diluted share, that same profit rose 9.4% to $5.70 because Kinsale bought back 269,004 shares for $100.0 million during the quarter, matching the second quarter's spending pace.
Those purchases lowered the diluted share count by 3.3% from a year ago to 22.5 million shares. Two other positives got no new numbers in the release: internal artificial intelligence tools and new broker appointments, which await the conference call.
What to watch: fourth-quarter share repurchases against the remaining $237.5 million authorization. Another $100 million quarter would keep per-share profit growing faster than the underlying insurance business.
🐻 Bear Case
Earned Premium Growth Slowed Toward the Shrinking Policy Book
Gross written premiums, the total value of policies sold before sharing risk with reinsurers, fell 4.8% from a year ago to $462.9 million. For the past year, Kinsale kept net earned premiums—the portion of policies recognized as revenue as coverage time passes—growing fast by keeping a larger share of policies on its own books starting in June 2025.
- Gross written premiums: $462.9 million, down 4.8% from a year ago
- Net retention share: 86.2% of gross premiums by our math, up from 83.3% a year ago
- Net earned premiums: $423.5 million, up 3.0% from a year ago after 8.9% growth last quarter
Because that June 2025 reinsurance shift is now more than a year old, its boost to revenue growth faded this quarter. As a result, underwriting income—profit from insurance policies before investment returns—rose just 1.3% to $107.1 million, making profit growth depend on investment income and reserve releases.
What to watch: net earned premium growth in the fourth quarter. Since policies earn revenue over twelve months, three straight quarters of falling policy sales point to flat or shrinking earned premiums next.
Casualty Growth Nearly Stopped as Property Kept Falling
"Our underwriting results this quarter demonstrate discipline in a competitive market," chief executive Michael P. Kehoe said. The specialty insurer blamed the overall sales drop on "heightened competition in the Company's property divisions", where gross written premiums fell 19.3% from a year ago, including a 26.8% drop in the Commercial Property Division.
Yet the slowdown now reaches well beyond property coverage. Instead of reporting sales growth for all divisions outside Commercial Property—which slowed from 12.3% a year ago to 3.7% last quarter—Kinsale split out its casualty business, which covers liability claims. Casualty gross written premiums grew just 0.9% in the quarter and 3.0% over the first nine months.
The company said casualty sales reflected "an increase in bound accounts offset in part by a change in business mix towards smaller accounts". That means Kinsale is signing more individual policies, but collecting less money per policy, so the non-property engine is no longer offsetting property declines.
What to watch: growth outside Commercial Property in the quarterly filing's division table. A further drop toward zero would confirm that competition and smaller policy sizes have stalled the casualty divisions too.
Reinsurance Changes Pushed Operating Costs Above the Target
Kinsale tracks underwriting profitability using the combined ratio, the share of earned premiums and fees spent on claims and operating costs. That ratio worsened by 0.5 percentage points from a year ago to 75.4%, because the expense ratio—underwriting, acquisition and insurance expenses as a share of earned premiums and fees—rose 1.0 percentage point to 22.0%.
The insurer said expenses rose because of "lower ceding commissions as a result of increased retention on the Company's reinsurance treaties". When Kinsale hands less business to reinsurers, it receives less commission back to offset its own overhead, pushing the expense ratio past the 21.7% run-rate finance chief Bryan Petrucelli gave last quarter. Meanwhile, the loss ratio improved by 0.5 points to 53.4% only because savings from prior years' claim reserves grew to 4.5 percentage points, up from 3.7 points a year ago.
What to watch: the split between broker commissions and overhead costs in the quarterly filing. It will show whether internal software savings are offsetting the lost reinsurance commissions.
Risks this quarter didn't answer
Four standing concerns from prior quarters could not be checked from the earnings release alone and await the conference call or the quarterly filing.
- Industry rate changes: Kinsale benchmarks pricing to the AMWINS index, which fell 5.9% last quarter and is only discussed on the conference call.
- Delegated underwriting competition: whether managing general agents and fronting carriers are still underpricing long-tail casualty and construction policies.
- Catastrophe treaty retention: the exact per-event retention limit and property share in the book heading into the fourth quarter.
- Venetian Hills lawsuit: any update on the Georgia Supreme Court review of the vacated $140 million wrongful-death verdict, which lives in the filing's legal footnote.

Portfolio Repositioning Cut Reported Profit by $38 Million
Reported net income fell 30.7% from a year ago to $98.1 million because Kinsale rearranged its investments to "improve expected long-term returns". The company sold winning stocks and losing bonds at the same time; accounting rules already counted the stock gains in earlier quarters, but recorded the $37.6 million pre-tax bond loss upon sale, leaving book value untouched.
💲 Other KPIs
Unearned premiums—cash collected for policy coverage not yet delivered—fell 5.2% from a year ago and dropped $28.9 million from last quarter by our math. The balance has shrunk from a year ago for two straight quarters, pointing to slower earned revenue ahead.
Money set aside for future claim payments rose 20.2% from a year ago and $131.7 million from last quarter. As the insurer writes more long-tail casualty policies that take years to settle, unpaid reserves keep growing even while policy sales shrink.
Net worth per share rose 6.3% from a year ago and 0.7% from the end of 2025, but slipped 4.6% from $89.34 in the second quarter. Unrealized bond losses of $112.9 million after tax and $100.0 million of share buybacks reduced stockholders' equity during the period.
🔮 Guidance
Reduced by deployment. Kinsale does not issue revenue or profit forecasts, leaving its buyback authorization as its only forward commitment. After the board added $250.0 million in July to bring capacity to $337.5 million, the US insurer spent $100.0 million in the third quarter, leaving $237.5 million available.
❓ Key Questions
What was premium growth outside Commercial Property this quarter?
Kinsale previously reported gross written premium growth excluding the Commercial Property Division every quarter, which slowed to 3.7% in Q2. Replacing that figure with a 0.9% casualty growth rate makes it harder to track the exact six-quarter slowdown.
Why did casualty premium growth slow to under 1%?
Casualty gross written premiums grew just 0.9% in the third quarter, down from 3.0% for the nine-month period. Readers need to know how much of that slowdown came from lower policy rates versus the shift toward smaller accounts.
Where did the expense ratio land between commissions and overhead?
The expense ratio reached 22.0%, above the 21.7% run-rate management gave last quarter. Without the breakdown between net commissions and operating overhead, investors cannot see if internal software savings are offsetting lower reinsurance commissions.
How much did underlying property and casualty claim picks move?
The current accident year loss ratio before catastrophes was 57.4%, nearly unchanged from 57.3% a year ago despite falling property rates and a shift toward casualty policies. Division-level profitability remains undisclosed.
