CB — Q3 2026 Financial Report Analysis

Overview: hurricane-season losses took back the margin, buybacks kept EPS rising

Chubb's third quarter of 2026 (the three months to September 30) was a quarter where catastrophe losses, not the underlying business, set the headline. Pre-tax catastrophe losses (claims from storms, wildfires and other large natural or man-made events, net of reinsurance) were $705 million, against an unusually light $285 million a year earlier. That pushed the P&C combined ratio up to 84.1% from 81.8%. The combined ratio is the share of each premium dollar paid out in claims and expenses; under 100% means the insurer made money on underwriting before counting any investment income. So Chubb was still keeping about 16 cents of underwriting profit per premium dollar, just less than last year's 18 cents.

Net income attributable to Chubb rose 1.5% to $2.84 billion, and diluted EPS rose 4.4% to $7.30. Core operating income, Chubb's preferred non-GAAP measure (net income without investment gains and losses and a few items management treats as non-recurring), fell 2.2% to $2.98 billion. Per share it still edged up 0.8% to $7.66, because there were 2.9% fewer shares. These figures come from the October 20, 2026 earnings release (Exhibit 99.1 to Form 8-K) and the accompanying financial supplement. The full 10-Q for the quarter isn't filed yet, so reserve detail and the MD&A narrative are not available.

Key metrics

*Total revenues are net premiums earned plus net investment income, net realized gains (losses) and market risk benefit gains (losses), the same lines Chubb's 10-Q totals as revenue. The figure is summed here from the supplement's statement of operations because the release doesn't print a total.

Revenue was nearly flat even though premiums earned grew 3.9%. The reason is that net realized investment results swung from a $283 million gain a year ago to a $455 million loss. Underneath that, the insurance and investment engines both grew.

What the combined ratio says

The combined ratio has three parts: the loss ratio (claims, 58.7%), the acquisition cost ratio (commissions and other costs of winning business, 18.3%) and the administrative expense ratio (7.1%). The loss ratio rose 2 points. The supplement breaks that down:

• Catastrophes: $705 million, or 5.4 points of the combined ratio, versus 2.3 points a year ago. The extra $420 million of catastrophe losses is more than the $198 million drop in underwriting income.
• Reserve releases: Chubb released $511 million of reserves set aside for claims from earlier years (favorable "prior period development"), worth 3.9 points, versus $361 million and 3.0 points a year ago. That cushioned some of the catastrophe hit.
• The underlying business: on a "current accident year ex-catastrophe" basis, which strips out both of the above to show the margin on policies written for this year, the ratio was 82.6% versus 82.5%. Underwriting income on that basis rose 3.3% to $2.26 billion.

The acquisition cost ratio rose 0.6 points while the administrative ratio fell 0.3 points. The release ties the higher acquisition costs to mix: the business Chubb is growing (overseas, consumer) carries higher commissions than the large-account property it is shrinking.

Premium growth by segment

• North America Commercial was the weak spot for growth. Major accounts and wholesale excess-and-surplus business (specialty coverage for hard-to-place risks) fell 5.0%. Chubb says that excluding deliberate cuts to large-account property and financial lines, including buying more reinsurance, the segment grew 1.7%. Its combined ratio rose 4.8 points: 3.1 points from catastrophes, 1.0 point from a higher underlying loss ratio and 0.3 points from expenses, all of which the release attributes to the shift away from property business.
• North America Personal (homeowners, auto and other coverage for individuals) was the strongest unit. Its 60.3% combined ratio improved 4.8 points, helped by 4.3 points of larger reserve releases and a 2.2-point lower underlying loss ratio, partly offset by 1.7 points of extra catastrophe losses.
• Overseas General grew 6.7%, or 5.2% in constant dollars (constant dollars removes the effect of exchange-rate moves). Latin America rose 11.7%, Asia 7.5% and Europe 6.8%. Its combined ratio rose 3.1 points, with 5.0 points from catastrophes.
• Life Insurance segment income rose 11.4% to $369 million. Premiums written grew only 1.4% because a large one-time deal in the prior-year quarter cost 8.8 points of International Life growth. Including deposits on investment-type policies, which don't count as revenue under accounting rules, international life production rose 15.7%.

Investments: the steadier engine

Net investment income rose 8.6% to a record $1.79 billion. The adjusted figure, which adds income from private equity partnerships and is the one Chubb uses in core earnings, rose 6.3% to $1.89 billion. Management credits higher interest rates on new bond purchases. That income is now almost the size of P&C underwriting income ($2.06 billion), which is why a bad catastrophe quarter dents earnings without sinking them.

The same higher rates cut the market value of bonds Chubb already owns. The release puts after-tax realized and unrealized investment losses at $4.48 billion for the quarter, partly offset by $551 million of currency gains. Accumulated other comprehensive income (AOCI), the balance-sheet line where unrealized gains and losses on bonds collect before they are sold, went from -$4.98 billion at December 31 to -$9.48 billion. Book value per share fell 2.1% from June 30 to $191.43, even though excluding AOCI it rose 2.6% in the quarter.

Chubb also said its Strategic Holdings partnership with KKR agreed to sell its stake in USI Insurance Services to Aon. Chubb expects a $460 million realized gain on a $740 million investment. That gain is expected, not yet booked, and as a realized gain it will lift GAAP net income but not core operating income.

What the headline numbers hide

• Buybacks did all of the per-share growth in core earnings. Core operating income fell 2.2% while core EPS rose 0.8%; diluted shares averaged 389.4 million versus 400.9 million. Chubb bought back $1.18 billion of stock in the quarter at an average $344.32 a share and paid $393 million of dividends.
• GAAP net income beat core earnings for reasons outside the insurance business. Net income rose 1.5% while core operating income fell 2.2%. The gap is in the items core excludes: market risk benefit losses (tied to guarantees on certain life and annuity products) shrank to $55 million after tax from $120 million, and a Bermuda tax item flipped from a $36 million charge to a $60 million benefit. The effective tax rate fell to 18.9% from 21.9%.
• Chubb's share of profit rose while total company profit fell. Consolidated net income, including outside shareholders in businesses Chubb doesn't fully own, fell 11.9% to $2.74 billion. Income attributable to those minority holders swung from +$306 million to -$108 million, which is why Chubb's own share still rose. The release doesn't explain the swing; the 10-Q should.
• Cash conversion was strong. Operating cash flow was a record $6.07 billion, or $5.55 billion adjusted (Chubb removes investing activity by consolidated Huatai asset-management entities), against net income of $2.74 billion. Year to date, adjusted operating cash flow is $12.83 billion versus $8.02 billion of Chubb net income. Insurers collect premiums before they pay claims, so this is normal for a growing book, but it confirms earnings are backed by cash.
• A definition change, applied to both years. From this quarter, segment and core operating income exclude amortization of most purchased intangibles. Prior periods were restated, so the year-over-year comparisons above are like-for-like. Figures in earlier reports, including ours for Q2, were on the old definition.
• Written premiums are growing slower than earned premiums (+1.9% versus +3.9%). Premiums are earned over the life of a policy, so slower written growth today tends to show up as slower earned revenue in coming quarters.

Did last time's read hold up?

Our Q2 2026 report expected premium growth to stay in low single digits in constant dollars while Chubb shrank large-account property, flagged a flat underlying combined ratio (82.2%) as a sign margins were no longer widening, and named catastrophe losses in the peak hurricane months as the main risk to Q3. All three held. Consolidated premiums grew 1.8% in constant dollars with major accounts down 5.0%. The underlying ratio was 82.6%, flat to slightly worse. Catastrophes were the swing factor behind the lower underwriting income. The other item we flagged, adverse reserve development on molestation claims in the run-off book, can't be checked until the 10-Q is filed. The release reports $511 million of favorable development overall.

Takeaway: Strip out catastrophes and reserve releases and Chubb's underwriting margin was unchanged at 82.6%, while investment income grew 8.6%. The 2.2% fall in core operating income came from $420 million more storm losses than in an unusually quiet prior-year quarter. The bigger issue going forward is growth: premiums written grew only 1.9%, and North America commercial shrank. With underwriting margins flat, earnings per share now depends mainly on investment income and buybacks.

Outlook

Chubb gives no numerical guidance. Chief executive Evan Greenberg said the commercial P&C market "continues to grow more competitive... particularly in the U.S. and London". He said he "fully expect[s] North America commercial growth to improve in future quarters" and is aiming for "double-digit growth in tangible book value". On the reported basis, tangible book value per share grew 5.7% year over year. Excluding AOCI it grew 15.4%, so meeting that goal on the reported number depends partly on where interest rates go.

Our read: with commercial pricing softening, premium growth looks likely to stay in low single digits until North America commercial stops shrinking. That makes the Q4 segment numbers the thing to watch. Investment income should keep rising as maturing bonds are reinvested at higher yields, and buybacks at the current pace keep shrinking the share count, which is down 2.9% from a year ago. The expected $460 million USI gain will flatter GAAP net income when it is booked, but not core earnings. The 10-Q, due in the coming weeks, should explain the minority-interest swing and update the run-off reserve picture.
