SIGI — Q3 2026 Financial Report Analysis

Better underwriting on a shrinking book

Selective Insurance earned $128.7 million in the third quarter of 2026, up 11.5% from a year earlier, and diluted EPS rose 14% to $2.11 even though revenue slipped 2.5% to $1.33 billion. The improvement came from the insurance itself: the combined ratio, the share of each premium dollar spent on claims and expenses (below 100% means the insurance business made money before investment income), improved to 96.8% from 98.6%. Most of that gap is one item that did not repeat. A year ago Selective added $40 million to reserves for older commercial auto and umbrella claims; this quarter it added nothing. At the same time the company is deliberately writing less business: net premiums written, the premiums it keeps after buying its own reinsurance, fell 7%.

Key figures

The loss ratio is claims and claim-handling costs as a share of premiums earned. The expense ratio is the cost of selling and running the policies.

What moved the combined ratio

The 10-Q splits the loss ratio into four parts, and they moved in different directions:

• No reserve charge this year. In Q3 2025 Selective raised its estimates for claims from earlier years by $40 million ($35 million commercial auto, $5 million personal auto), on what the filing calls "increased severities in accident years 2022 through 2024." This quarter there was "no prior year casualty reserve development in any segment or line of business." On its own, that accounts for 3.3 points of improvement, more than the whole 1.8-point gain in the combined ratio.
• Price increases are showing up in this year's claims costs. Current-year casualty losses (liability claims from policies written this year) fell 2.3 points. Management attributes this to "the earned impact of the rate and underwriting actions."
• Weather cost more. Catastrophe losses rose to $64.1 million from $24.9 million. The filing points to "higher frequency and severity of winter storms and thunderstorm events" in Selective's states.
• Expenses rose as a share of premiums. The expense ratio went up 1.5 points because "lower NPE has put pressure on our underwriting expense ratio". Fixed costs are being spread over fewer premium dollars.

Our own calculation strips out catastrophes and prior-year reserve changes. On that basis the combined ratio was about 91.4% versus 93.2% a year ago, a similar 1.8-point improvement. So the underlying book did get better, not just the one-offs.

Segments: commercial auto fixed, E&S and property gave some back

• Commercial auto produced the biggest swing, from a 117.6% combined ratio to 102.0%, because last year's quarter carried $35 million of reserve additions. The line still lost money. Selective cut its premiums 11% by "tightening underwriting guidelines for fleet exposures," and retention fell to 80% from 82%.
• General liability stayed at 106.6%, losing $20.1 million on underwriting, even though renewal prices rose 7.9%. This is the line where the filing says assumed claim costs keep rising because of "social inflation" (bigger jury awards and legal costs). It makes up about a third of commercial premiums and still loses money.
• E&S covers harder-to-place risks that standard insurers turn down. Its combined ratio worsened 10.3 points to 86.5%. Underwriting profit fell 43% to $21.3 million, driven by "higher embedded severity assumptions due to social inflation" along with higher property and catastrophe losses. Premiums fell 2% as "more capacity entering the excess and surplus lines marketplace" brought more competition.
• Personal lines improved to 103.2% from 110.1% but still lost $3.0 million. New business was down 36% because of a competitive auto market and limits Selective has placed on growth in New Jersey.

Why premiums are falling

Selective is choosing profit over volume, and the filing says so plainly. Lower premiums "reflect reduced new business in a competitive environment and our granular pricing actions to drive lower retention on underperforming business." Direct new business premiums fell to $202.8 million from $233.2 million. Renewal price increases slowed to 5.6% from 9.6% a year ago. Commercial lines retention, the share of customers who renew, held at 82%. Because premiums are earned over the life of a policy, the cut in premiums written is only starting to reach revenue: net premiums earned fell 2% in the quarter but are still up 2% for the year to date.

What the headline numbers hide

• GAAP and operating results moved in opposite directions on investments. GAAP net income includes $19.4 million of pre-tax realized and unrealized investment losses, against $8.1 million of gains a year earlier. That is why operating EPS ($2.37, +35%) is well ahead of GAAP EPS ($2.11, +14%). Operating EPS excludes only these investment gains and losses. Both measures include the higher catastrophe losses.
• Book value barely grew because of bond prices. Book value per share rose only 1.0% to $55.02. Excluding unrealized investment losses, the company's adjusted book value per share rose 11% to $62.00. The gap comes from a $433 million rise since December in pre-tax unrealized losses on the bond portfolio, "primarily due to higher interest rates." These are paper losses on bonds Selective says it does not intend to sell. They lower reported equity today, and they shrink as the bonds approach maturity.
• Some of the EPS growth came from buybacks. Diluted shares fell 1.9% to 59.9 million. Selective repurchased 1.3 million shares for $116.9 million in the first nine months, which explains why EPS (+14%) grew faster than net income (+11.5%). The tax rate was roughly flat (20.9% vs 21.2%).
• Investment income is doing much of the work. After-tax net investment income rose 16% to $127.3 million, which the filing credits to a higher portfolio yield (4.4% after tax vs 4.1%) and new cash being invested. It contributed 15.2 points of the 15.1% ROE. Insurance operations contributed 3.5 points.
• Cash conversion is healthy. Operating cash flow was $817.7 million for nine months, against net income of $355.7 million. That is normal for an insurer collecting premiums ahead of paying claims, though it was down from $856.8 million on "lower levels of cash received for premiums."
• Some favorable property reserve releases. For the nine months, Selective released $22.5 million of reserves on prior-year property claims. Casualty reserves, the ones that hurt last year, were left unchanged.

Takeaway: The 1.8-point combined-ratio improvement is mostly the absence of last year's $40 million reserve charge, not a turnaround that is fully visible yet. The underlying book is improving, but premiums are falling 7% and general liability is still losing money. Selective is getting smaller to get more profitable, and investment income is carrying most of the return.

Outlook

Management kept its full-year 2026 GAAP combined ratio guidance at 96.5% to 97.5%, but cut the catastrophe assumption inside it to 5.5 points from 6.0 points in the Q2 filing. Since the overall range did not change, the guidance now implies slightly worse non-catastrophe results than it did three months ago. After-tax investment income guidance went up to $490 million from $480 million (it was $465 million at the start of the year). Management also expects a 21.5% effective tax rate and 59.9 million diluted shares.

The nine-month combined ratio is 97.7%, including 5.8 points of catastrophes. Reaching the guided range means the fourth quarter has to come in around or below 96%, which depends on a quiet storm quarter and no new reserve charges.

What to watch in the Q4 and full-year report (results 8-K likely late January 2027, 10-K around early-to-mid February):

1. Whether reserves stay unchanged. Three quarters with no casualty reserve additions is the key change from 2025. Year-end reviews are when charges have shown up before, especially in commercial auto and general liability.
2. Premium decline versus margin. If premiums written keep falling 5-8% while renewal price increases slow (5.6% this quarter), the expense ratio will keep rising, as it did this quarter (+1.5 points).
3. E&S profitability. Watch whether the 86.5% combined ratio was a single bad quarter or the start of softer pricing in that market.
