News Release

Chubb Reports Strong Second Quarter Net Income Per Share of

$5.06 and Record Core Operating Income Per Share of $3.62;

Consolidated Net Premiums Written Up 14.3% Globally, with

Commercial P&C Lines Up 19.9%; Best Organic P&C Growth in Over

15 Years

· Net income was strong at $2.27 billion versus a net loss of $(331) million prior year, and core operating income was a record $1.62 billion versus a core operating loss of $(254) million prior year.

· P&C net premiums written were up 15.5% globally for the quarter and 12.6% for the first six months, powered by commercial lines and the best organic P&C growth since 2004. The quarter’s result comprised growth of 20.7% in commercial lines excluding Agriculture, 11.0% in Agriculture and 5.6% in P&C consumer lines. Foreign exchange had a positive impact on P&C net premiums written growth of 2.8 percentage points in the quarter.

· The P&C combined ratio was 85.5% compared with 112.3% prior year. P&C current accident year underwriting income excluding catastrophe losses was a record $1.20 billion, up 27.0%, driven by a P&C current accident year combined ratio excluding catastrophe losses of 85.4% compared with 87.4% prior year. The 2.0 percentage point decrease was substantially driven by improvement in the loss ratio.

· Pre-tax and after-tax catastrophe losses, net of reinsurance and including reinstatement premiums, were $280 million and $226 million, respectively, compared with $1.81 billion and $1.51 billion, respectively, prior year.

· Pre-tax net investment income was $884 million, up 7.0% from the prior year, and adjusted net investment income was $945 million, up 9.4% from the prior year. Both were record results.

· Annualized return on equity (ROE) and core operating ROE were 15.2% and 11.5%, respectively. Annualized core operating return on tangible equity was 17.7%.

· Book and tangible book value per share were up 4.2% and 5.0%, respectively, for the quarter, and were up 3.8% and 4.3%, respectively, from December 31, 2020.

ZURICH – July 27, 2021 – Chubb Limited (NYSE: CB) today reported net income for the quarter ended June 30, 2021 of $2.27 billion, or $5.06 per share, and core operating income of $1.62 billion, or $3.62 per share. Book value was favorably impacted by total after-tax net realized and unrealized gains of $1.52 billion, including a $1.35 billion gain in the investment portfolio, principally due to lower interest rates and mark-to-market gains on private equities, and favorable foreign exchange of $215 million. Book and tangible book value per share now stand at $136.90 and $91.48, respectively.

Evan G. Greenberg, Chairman and Chief Executive Officer of Chubb Limited, commented: “Chubb had simply an outstanding quarter, highlighted by record core operating earnings and underwriting results. We produced the best P&C premium revenue growth globally in over 15 years, powered by our commercial P&C businesses and supported by continued robust commercial P&C pricing. Operating earnings in the quarter were $1.62 billion or $3.62 per share.

“Our published and current accident year combined ratios of 85.5% and 85.4%, respectively, reflect 200 basis points of underwriting margin improvement, almost entirely loss ratio-related. Current accident year underwriting income of $1.2 billion was up 27%, while on the other side of the balance sheet adjusted net investment income in the quarter of $945 million was also a record and up nearly 9.5% from prior year.

“P&C net premiums written were up 15.5% globally, with commercial premiums excluding agriculture up nearly 21%. For perspective, we have averaged double-digit commercial P&C growth over the past 10 quarters, and both second quarter and year-to-date growth were the strongest since 2004. In North America, we grew our commercial P&C premiums over 16%, while in our international operations premiums grew 33% on a published basis, or 24% in constant dollars. Growth in the quarter was broad based. Net premiums written in our consumer lines remain impacted by the pandemic’s effects on travel and other business and consumer-related activity but are beginning to improve and, in fact, increased 5.6% in the quarter.

“We are capitalizing on a strong commercial P&C pricing environment in most all important regions of the world. Overall rates increased in our North America and international commercial P&C businesses by 13.5% and 16%, respectively, and were well in excess of loss costs. From everything we see today, I am confident these market conditions will continue.

“Our company is firing on all cylinders – we are growing our business while we continue to expand underwriting margins. We will continue to outperform and deliver strong, sustainable shareholder value.”

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 the acquisition of The Chubb Corporation (Chubb Corp) of $22 million in Q2 2021 and $48 million for the six months ended June 30, 2021 and including investment income of $39 million in Q2 2021 and $80 million for the six months ended June 30, 2021 from partially owned investment companies (private equity partnerships) where our ownership interest is in excess of three percent that are accounted for under the equity method. 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), 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. These 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.

P&C underwriting income is calculated by subtracting adjusted losses and loss expenses, policy acquisition costs and administrative expenses from net premiums earned by our P&C operations. We use P&C underwriting income 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, income tax expense and adjusted net realized gains (losses).

P&C current accident year underwriting income excluding catastrophe losses is P&C underwriting income adjusted to exclude 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.

Core operating income, net of tax, excludes from net income the after-tax impact of adjusted net realized gains (losses) and the amortization of fair value adjustment of acquired invested assets and long-term debt related to the Chubb Corp acquisition. 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) because the amount of these gains (losses) are heavily influenced by, and fluctuate in part according to, the availability of market opportunities. We exclude the amortization of the fair value adjustments related to purchased invested assets and long-term debt due to

Chubb®, Chubb logo® and Chubb. Insured.^SM are trademarks of Chubb. 8

Chubb Limited News Release

the size and complexity of this acquisition. 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 shareholders’ equity for the period adjusted to exclude unrealized gains (losses) on investments, net of tax. For the ROTE calculation, the denominator is also adjusted to exclude goodwill and other intangible assets, net of tax. These measures enhances the understanding of the return on shareholders’ equity by highlighting the underlying profitability relative to shareholders’ equity and tangible equity excluding the effect of unrealized gains and losses on our investments.

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 better evaluation of our underwriting performance and enhances the understanding of the trends in our property and casualty 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 the company’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 the company’s P&C insurance business. We believe that these measures are useful and meaningful to investors as they are used by management to assess the company’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 shareholders’ equity less 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.

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 GAAP. However, we include life deposits in presenting growth in our life insurance business because new 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 29-35 in the Financial Supplement. These measures should not be viewed as a substitute for measures determined in accordance with GAAP, including premium, net income, return on equity, and net investment income.

(1) Q2 2021 P&C net premiums written growth was adversely impacted by lower year-over-year large structured transactions written of $241 million, partially offset by the prior year COVID-19 related exposure adjustments of $184 million on in-force policies. Excluding these items, P&C net premiums written increased 16.4% in the quarter and 13.1% YTD.

(2) In periods where core operating loss and net loss are recognized, inclusion of incremental dilution is anti-dilutive and therefore basic shares are used in the calculation of per share earnings. Refer to page 27 for additional details.

(1) Q2 2021 net premiums written growth was adversely impacted by lower year-over-year large structured transactions written of $241 million, partially offset by the prior year COVID-19 related exposure adjustments of $160 million on in-force policies. Excluding these items, net premiums written increased 18.0% in the quarter and 15.5% YTD.

(2) Major Accounts & Specialty: large corporate accounts and wholesale business. Commercial: principally middle market and small commercial accounts.

(1) Includes unvested restricted stock units that are not included in common shares outstanding as the shares are not issued until time of vesting, but are eligible to receive dividends (participating securities).

(2) In periods where core operating loss and net loss are recognized, inclusion of incremental dilution is anti-dilutive and therefore basic shares are used in the calculation of per share earnings. For the three and six months ended June 30, 2020, the effect of dilutive securities was 1,395,951 shares and 2,044,144 shares, respectively. Weighted-average shares outstanding used to calculate earnings per share for the 2021 periods and core operating income per share for the six months ended June 30, 2020 include the effect of dilutive securities.

Non-GAAP Financial Measures

(Unaudited)

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.

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, income tax expense and adjusted net realized gains (losses).

P&C CAY underwriting income excluding catastrophe losses (Cats) is P&C underwriting income (loss) adjusted to exclude P&C Cats and prior period development (PPD). We believe it is useful to exclude Cats, 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.

Adjusted losses and loss expenses include realized gains and losses on crop derivatives. These 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.

Adjusted policy benefits includes gains and losses from fair value changes in separate account assets, as well as the offsetting movement in separate account liabilities, for purposes of reporting Life Insurance underwriting income. The gains and losses from fair value changes in separate account assets that do not qualify for separate account reporting under GAAP have been reclassified from Other (income) expense. We view gains and losses from fair value changes in both separate account assets and liabilities as part of the results of our underwriting operations, and therefore these gains and losses are reclassified to adjusted policy benefits.

Adjusted net investment income is net investment income excluding the amortization of the fair value adjustment on acquired invested assets from the acquisition of The Chubb Corporation (Chubb Corp) and including investment income from partially-owned investment companies (private equity partnerships) where our ownership interest is in excess of three percent that are accounted for under the equity method. 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), 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.

Adjusted interest expense is interest expense excluding the amortization of the fair value adjustment on acquired long-term debt, related to the Chubb Corp acquisition due to the size and complexity of this acquisition.

Other income (expense) - operating excludes from consolidated Other income (expense) the portion of net realized gains and losses related to unconsolidated entities, other income (expense) from private equity partnerships, and gains and losses from fair value changes in separate account assets that do not qualify for separate account reporting under GAAP. Net realized gains (losses) related to unconsolidated entities is excluded from core operating income (loss) in order to enhance the understanding of our results of underwriting operations as they are heavily influenced by, and fluctuate in part according to, market conditions. Other income (expense) from private equity partnerships and net realized gains and losses related to unconsolidated entities are recorded to Other income (expense) in our income statement on a GAAP basis.

P&C combined ratio excludes the Life Insurance segment. P&C loss and loss expense ratio and P&C combined ratio include adjusted losses and loss expenses in the ratio numerator. P&C expense ratio and P&C combined ratio include policy acquisition costs and administrative expenses in the ratio numerator. A reconciliation of combined ratio to P&C combined ratio is provided on pages 32-35.

CAY P&C combined ratio excluding catastrophe losses excludes Cats and PPD from the P&C combined ratio. We exclude Cats 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. The combined ratio numerator is adjusted to exclude Cats, net premiums earned adjustments on PPD, prior period expense adjustments and reinstatement premiums on PPD, and the denominator is adjusted to exclude net premiums earned adjustments on PPD and reinstatement premiums on Cats and PPD. In periods where there are adjustments on loss sensitive policies, these adjustments are excluded from PPD and net premiums earned when calculating the ratios. We believe this measure provides a better evaluation of our underwriting performance and enhances the understanding of the trends in our P&C business that may be obscured by these items. This measure is commonly reported among our peer companies and allows for a better comparison.

Expense ratio excluding accident and health (A&H) excludes the impact of our A&H business from our expense ratio. The expense ratio for the A&H business is typically higher than our traditional P&C business, and we believe that this measure provides better comparison to our peer companies that may not have a significant A&H block of business.

Global P&C performance metrics comprise consolidated operating results (including corporate) and exclude the operating results of the company’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 the company’s P&C insurance business. We believe that these measures are useful and meaningful to investors as they are used by management to assess the company’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.

Core operating income (loss), net of tax, excludes from net income, the after-tax impact of adjusted net realized gains (losses) and the amortization of fair value adjustment of acquired invested assets and long-term debt related to the Chubb Corp acquisition. 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) because the amount of these gains (losses) are heavily influenced by, and fluctuate in part according to the availability of market opportunities. We exclude the amortization of the fair value adjustments related to purchased invested assets and long-term debt due to the size and complexity of this acquisition. References to core operating income measures mean net of tax, whether or not noted.

Core operating effective tax rate is income tax expense (benefit) excluding tax expense (benefit) on adjusted net realized gains (losses) and tax benefit on amortization of fair value of acquired invested assets and debt, divided by income excluding adjusted net realized gains (losses) before tax and amortization of fair value of acquired invested assets and debt before tax. We believe the use of this measure is meaningful to show the tax on the underlying performance of our insurance business, by excluding the tax on adjusted net realized gains (losses), the tax on amortization of the fair value adjustments related to purchased invested assets and long-term debt. Refer to the definition of core operating income (loss), net of tax above for more information on these adjustments.

Book value per common share, is shareholders’ equity divided by the shares outstanding. Tangible book value per common share, is shareholders’ equity less 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. Book value per common share excluding mark-to-market, excludes unrealized investment gains (losses). Tangible book value per common share excluding mark-to-market, excludes goodwill and other intangible assets, net of tax, as well as unrealized investment gains (losses), net of tax. We exclude unrealized investment gains (losses) because the amount of these gains (losses) is heavily influenced by changes in market conditions, including interest rate changes, and we believe that excluding these gains and losses would highlight the underlying growth in book value and tangible book value.

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 GAAP. However, we include life deposits in presenting growth in our life insurance business because new life deposits are an important component of production and key to our efforts to grow our business.

Core operating ROE

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 shareholders’ equity for the period adjusted to exclude unrealized gains (losses) on investments, net of tax. For the ROTE calculation, the denominator is also adjusted to exclude 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 unrealized gains and losses on our investments.

The P&C combined ratio includes the impact of realized gains and losses on crop derivatives. These derivatives were purchased to provide economic benefit, in a manner similar to reinsurance protection, in the event that a significant decline in commodity pricing will impact underwriting results.

Glossary

Chubb Limited Consolidated comprises all segments including Corporate.

P&C combined ratio: The sum of the loss and loss expense ratio, policy acquisition cost ratio and the administrative expense ratio excluding the life business and including the realized gains and losses on the crop derivatives.

Book value per common share: Shareholders’ equity divided by the shares outstanding.

Tangible book value per common share: Shareholders’ equity less goodwill and other intangible assets, net of tax, divided by the shares outstanding.

Average market yield of fixed maturities: Weighted average yield to maturity of our fixed income portfolio based on the market prices of the holdings as of that date.

Average yield on invested assets: Adjusted net investment income divided by average cost of fixed maturities and other investments, and average market value of equity securities.

Total capitalization: The sum of the short-term debt, long-term debt, trust preferreds, and shareholders’ equity.

Catastrophe losses (Cats): We generally define catastrophe loss events consistent with the definition of the Property Claims Service (PCS) for events in the U.S. and Canada. PCS defines a catastrophe as an event that causes damage of $25 million or more in insured losses and affects a significant number of insureds, including from pandemics such as COVID-19. For events outside of the U.S. and Canada, we generally use a similar definition. Catastrophe loss events are events that occurred in the current calendar year only. Changes in catastrophe loss estimates in the current calendar year that relate to loss events that occurred in previous calendar years are considered prior period development.

Prior period development (PPD) arises from changes to loss estimates recognized in the current year that relate to loss events that occurred in previous calendar years and excludes the effect of losses from the development of earned premium from previous accident years.

Reinstatement premiums are additional premiums paid on certain reinsurance agreements in order to reinstate coverage that had been exhausted by loss occurrences. The reinstatement premium amount is typically a pro rata portion of the original ceded premium paid based on how much of the reinsurance limit had been exhausted.

Net premiums earned adjustments within prior period development are adjustments to the initial premium earned on retrospectively rated policies based on actual claim experience that develops after the policy period ends. The premium adjustments correlate to the prior period loss development on these same policies and are fully earned in the period the adjustments are recorded.

Prior period expense adjustments typically relate to either profit commission reserves or policyholder dividend reserves based on actual claim experience that develops after the policy period ends. The expense adjustments correlate to the prior period loss development on these same policies.

Segment income (loss) includes underwriting income (loss), adjusted net investment income, other income (expense) – operating, and amortization expense of purchased intangibles.

Commercial P&C lines includes Commercial P&C, Agriculture and Reinsurance lines of business.

Consumer P&C lines includes Personal and Global accident and health (A&H) lines of business.

NM: Not meaningful.
