Chubb Limited News Release

Evan G. Greenberg, Chairman and Chief Executive Officer of Chubb Limited, commented: “We had a simply outstanding quarter. The results again put a point on the broad-based, diversified nature of our company geographically, by customer segment both and within commercial and consumer, by product and distribution channel. Core operating income of $3 billion was a record, up 29%, driven by record underwriting and investment income and double-digit growth in life income. Our core operating EPS was also a record, $7.49 per share, up 31%.

“Underwriting income on both a published and current accident year ex-catastrophe basis was supported by solid premium growth and underwriting margin improvement. Published underwriting income of $2.3 billion was up 55% from a year ago, with a record combined ratio of 81.8% — about six percentage points better than a year earlier. While we benefited from light CAT losses in the quarter, the real story is our underlying underwriting results, which were excellent, and very strong prior period reserve development. Current accident year underwriting income excluding CATs was a record $2.2 billion, up 10%, with a combined ratio of 82.5%, nearly a full-point improvement from prior year, with most all of it coming from loss ratio improvement.

“Adjusted net investment income of $1.8 billion was up 8.3%. Financial, economic and fiscal conditions favor continued attractive fixed income and alternative investment portfolio returns on our growing invested asset.

“Total company premiums grew 7.5%, with P&C up 5.3% and life up over 24.5%. All businesses and regions of the world contributed to growth. North America was up 4.4%, including growth of 8.1% in personal insurance and 3.5% in commercial, or 6.2% excluding the impact of two items that benefited the prior year. Overseas General was up 9.7%, including growth of 15.5% in consumer insurance and 5.8% in commercial insurance; Asia, Latin America and Europe were up 14.3%, 10.6% and 4.8%, respectively. Our balance of business and deep local presence provides us a wide range of opportunities around the world, which supports long-term, profitable growth, and it gives us additional freedom to manage a transitioning commercial P&C cycle with discipline.

“In the quarter, we increased share buybacks since our stock is trading well below intrinsic value. Given our earning power, increased buyback activity will continue, while at the same time we build additional capital and our invested asset base.

“In sum, Chubb’s fundamentals and our positioning are excellent, and our balance sheet, starting with our loss reserves, has never been stronger. I am confident we will maintain superior earnings growth, including double-digit growth in EPS, book and tangible book value, with core operating ROE increasing to 14% plus over the medium term, CATs and FX notwithstanding.”

Chubb Limited News Release

Regulation G – Non-GAAP Financial Measures

In presenting our results, we included and discussed certain non-GAAP measures. These non-GAAP measures, which may be defined differently by other companies, are important for an understanding of our overall results of operations and financial condition. However, they should not be viewed as a substitute for measures determined in accordance with generally accepted accounting principles (GAAP).

Throughout this document there are various measures presented on a constant-dollar basis (i.e., excludes the impact of foreign exchange). We believe it is useful to evaluate the trends in our results exclusive of the effect of fluctuations in exchange rates between the U.S. dollar and the currencies in which our international business is transacted, as these exchange rates could fluctuate significantly between periods and distort the analysis of trends. The impact is determined by assuming constant foreign exchange rates between periods by translating prior period results using the same local currency exchange rates as the comparable current period.

Adjusted net investment income is net investment income excluding the amortization of the fair value adjustment on acquired invested assets from certain acquisitions of $1 million and $5 million in Q3 2025 and Q3 2024, and including investment income of $127 million in both Q3 2025 and Q3 2024, from partially owned investment companies (private equity partnerships) where our ownership interest is in excess of 3% that are accounted for under the equity method. The amortization of the fair value adjustment on acquired invested assets was $7 million and $14 million for the nine months ended September 30, 2025 and 2024, and the investment income from private equity partnerships was $349 million and $304 million for the nine months ended September 30, 2025 and 2024. The mark-to-market movement on these private equity partnerships are included in adjusted net realized gains (losses) as described below. We believe this measure is meaningful as it highlights the underlying performance of our invested assets and portfolio management in support of our lines of business.

Adjusted net realized gains (losses) and other, net of tax, includes net realized gains (losses) and net realized gains (losses) recorded in other income (expense) related to unconsolidated subsidiaries, and excludes realized gains and losses on crop derivatives and realized gains and losses on underlying investments supporting the liabilities of certain participating policies related to the policyholders’ share of gains and losses. The crop derivatives were purchased to provide economic benefit, in a manner similar to reinsurance protection, in the event that a significant decline in commodity pricing impacts underwriting results. We view gains and losses on these derivatives as part of the results of our underwriting operations, and therefore realized gains (losses) from these derivatives are reclassified to adjusted losses and loss expenses. The realized gains and losses on underlying investments supporting the liabilities of certain participating policies have been reclassified from net realized gains (losses) to adjusted policy benefits. We believe this better reflects the economics of the liabilities and the underlying investments supporting those liabilities. Other includes integration expenses and the amortization of fair value adjustment of acquired invested assets and long-term debt related to certain acquisitions. See Core operating income, net of tax for further description of these items.

P&C underwriting income (loss) excludes the Life Insurance segment and is calculated by subtracting adjusted losses and loss expenses, adjusted policy benefits, policy acquisition costs and administrative expenses from net premiums earned. We use underwriting income (loss) and operating ratios to monitor the results of our operations without the impact of certain factors, including net investment income, other income (expense), interest expense, amortization expense of purchased intangibles, integration expenses, amortization of fair value of acquired invested assets and debt, income tax expense, adjusted net realized gains (losses), and market risk benefits gains (losses).

P&C current accident year underwriting income excluding catastrophe losses is P&C underwriting income adjusted to exclude P&C catastrophe losses and prior period development (PPD). We believe it is useful to exclude catastrophe losses, as they are not predictable as to timing and amount, and PPD as these unexpected loss developments on historical reserves are not indicative of our current underwriting performance. We believe the use of these measures enhances the understanding of our results of operations by highlighting the underlying profitability of our insurance business. References in this release to “current accident year” metrics exclude catastrophe losses and prior period development, unless stated otherwise.

Chubb Limited News Release

Core operating income relates only to Chubb income, which excludes noncontrolling interests. It excludes from Chubb net income the after-tax impact of adjusted net realized gains (losses) and other, which include items described in this paragraph, and market risk benefits gains (losses). We believe this presentation enhances the understanding of our results of operations by highlighting the underlying profitability of our insurance business. We exclude adjusted net realized gains (losses) and market risk benefits gains (losses) because the amount of these gains (losses) is heavily influenced by, and fluctuates in part according to, the availability of market opportunities. In addition, we exclude the amortization of fair value adjustments on purchased invested assets and long-term debt related to certain acquisitions due to the size and complexity of these acquisitions. We also exclude integration expenses, which include legal and professional fees and all other costs directly related to acquisition integration activities. The costs are not related to the ongoing activities of the individual segments and are therefore included in Corporate and excluded from our definition of segment income. We believe these integration expenses are not indicative of our underlying profitability, and excluding these integration expenses facilitates the comparison of our financial results to our historical operating results. Additionally, we exclude the non-recurring tax benefit from the Bermuda Economic Transition Adjustment enacted in 2023 and adjusted in 2024 and subsequent years’ amortization of the related deferred tax asset, which we believe provides investors with a better view of our operating performance, enhances the understanding of the trends in the underlying business, improves comparability between periods and provides increased transparency compared to the prior presentation of the non-recurring tax benefit. References to core operating income measures mean net of tax, whether or not noted.

Core operating return on equity (ROE) and Core operating return on tangible equity (ROTE) are annualized non-GAAP financial measures. The numerator includes core operating income (loss), net of tax. The denominator includes the average Chubb shareholders’ equity for the period adjusted to exclude unrealized gains (losses) on investments, current discount rate on future policy benefits (FPB), and instrument-specific credit risk on market risk benefits (MRB), all net of tax and attributable to Chubb. For the ROTE calculation, the denominator is also adjusted to exclude Chubb goodwill and other intangible assets, net of tax. These measures enhance the understanding of the return on shareholders’ equity by highlighting the underlying profitability relative to shareholders’ equity and tangible equity excluding the effect of these items as these are heavily influenced by changes in market conditions. We believe ROTE is meaningful because it measures the performance of our operations without the impact of goodwill and other intangible assets.

P&C combined ratio is the sum of the loss and loss expense ratio, acquisition cost ratio and the administrative expense ratio excluding the life business and including the realized gains and losses on the crop derivatives, as noted above.

P&C current accident year combined ratio excluding catastrophe losses excludes the impact of P&C catastrophe losses and PPD from the P&C combined ratio. We believe this measure provides a useful evaluation of our underwriting performance and enhances the understanding of the trends in our P&C business that may be obscured by these items.

Global P&C performance metrics comprise consolidated operating results (including corporate) and exclude the operating results of Chubb’s Life Insurance and North America Agricultural Insurance segments. The agriculture insurance business is a different business in that it is a public sector and private sector partnership in which insurance rates, premium growth, and risk-sharing is not market-driven like the remainder of Chubb’s P&C insurance business. We believe that these measures are useful and meaningful to investors as they are used by management to assess Chubb’s global P&C operations which are the most economically similar. We exclude the North America Agricultural Insurance and Life Insurance segments because the results of these businesses do not always correlate with the results of our global P&C operations.

Tangible book value per common share is Chubb shareholders’ equity less Chubb goodwill and other intangible assets, net of tax, divided by the shares outstanding. We believe that goodwill and other intangible assets are not indicative of our underlying insurance results or trends and make book value comparisons to less acquisitive peer companies less meaningful.

Chubb Limited News Release

Book value per share and tangible book value per share excluding accumulated other comprehensive income (loss) (AOCI), excludes AOCI from the numerator because it eliminates the effect of items that can fluctuate significantly from period to period, primarily based on changes in interest rates and foreign currency movement, to highlight underlying growth in book and tangible book value.

Adjusted operating cash flow is Operating cash flow excluding the operating cash flow related to the net investing activities of Huatai’s asset management companies as it relates to the Consolidated Investment Products as required under consolidation accounting. Because these entities are investment companies, we are required to retain the investment company presentation in our consolidated results, which means, we include the net investing activities of these entities in our operating cash flows. Chubb has elected to remove the impact of net investing activities of consolidated investment companies from our operating cash flow as they may distort a reader’s analysis of our underlying operating cash flow related to the core insurance company operations. These net investing activities are more appropriately classified outside of operating cash flows, consistent with our consolidated investing activities. Accordingly, we believe that it is appropriate to adjust operating cash flow for the impact of consolidated investment products.

Life Insurance and International life insurance net premiums written and deposits collected includes deposits collected on universal life and investment contracts (life deposits). Life deposits are not reflected as revenues in our consolidated statements of operations in accordance with U.S. GAAP. However, we include life deposits in presenting growth in our life insurance business because life deposits are an important component of production and key to our efforts to grow our business.

See the reconciliation of Non-GAAP Financial Measures on pages 27-33 in the Financial Supplement. These measures should not be viewed as a substitute for measures determined in accordance with GAAP, including premium, net income, book value, return on equity, and net investment income.
