Segment Information

The following section provides analysis on the Company's 2026 first quarter performance by reportable segments. For additional details regarding the Company's reportable segments, please refer to the Company's Financial Supplement dated March 31, 2026. On August 1, 2024, the insurance segment completed the acquisition of the U.S. MidCorp and Entertainment insurance businesses from Allianz (MCE Acquisition). The Company's segment information includes the use of underwriting income (loss) and a combined ratio excluding catastrophic activity and prior year development (see ‘Comments on Non-GAAP Financial Measures' for further details).

Total impact		(0.4)%		(0.5)%	0.1

Combined ratio excluding catastrophic activity and prior year development		92.7%		91.1%	1.6

Gross premiums written by the insurance segment in the 2026 first quarter were 2.0% higher than in the 2025 first quarter, while net premiums written were 1.4% lower than in the 2025 first quarter. Adjusting for the non-renewal of certain programs related to the MCE Acquisition, net premiums written would have increased by 1.1% compared to the same quarter one year ago. Net premiums earned in the 2026 first quarter were 0.6% higher than in the 2025 first quarter and reflect changes in net premiums written over the previous five quarters.

The 2026 first quarter loss ratio reflected 4.2 points of current year catastrophic activity, compared to 9.5 points in the 2025 first quarter, primarily related to California wildfires. Estimated net favorable development of prior year loss reserves, before related adjustments, reduced the loss ratio by 0.7 points in the 2026 first quarter, compared to 0.9 points in the 2025 first quarter. The balance of the change in the loss ratio resulted, in part, from changes in the mix of business.

The underwriting expense ratio was 36.3% in the 2026 first quarter, compared to 34.1% in the 2025 first quarter. In the 2025 first quarter, the impact of the MCE Acquisition lowered the underwriting expense ratio by approximately 1.9 points, primarily due to the effects of the fair value estimation of the assets acquired at closing, including the non-recognition of deferred acquisition costs. The 2026 first quarter also included higher compensation costs compared to the 2025 first quarter and transitional expenses associated with the MCE Acquisition.

Combined ratio excluding catastrophic activity and prior year development		78.1%		78.0%	0.1

Gross premiums written by the reinsurance segment in the 2026 first quarter were 2.3% lower than in the 2025 first quarter, while net premiums written were 6.0% lower than in the 2025 first quarter. The lower level of net premiums written this quarter was primarily due to a reduction in property catastrophe business written at January 1, amplified by a lower level of reinstatement premiums relative to the 2025 first quarter, which included reinstatement premiums related to the California wildfires. Net premiums earned in the 2026 first quarter were 9.7% lower than in the 2025 first quarter and reflect changes in net premiums written over the previous five quarters.

The 2026 first quarter loss ratio reflected 5.4 points of current year catastrophic activity, compared to 21.7 points in the 2025 first quarter, primarily related to California wildfires. Estimated net favorable development of prior year loss reserves, before related adjustments, reduced the loss ratio by 8.3 points in the 2026 first quarter, compared to 5.9 points in the 2025 first quarter. The balance of the change in the loss ratio resulted, in part, from changes in the mix of business.

The underwriting expense ratio was 24.2% in the 2026 first quarter, compared to 24.9% in the 2025 first quarter. The 2025 first quarter amount included a lower level of contingent commissions on ceded business, primarily due to the impact of the California wildfires.

Total impact		(19.9)%		(21.8)%	1.9

Combined ratio excluding prior year development		42.2%		37.9%	4.3

Gross premiums written by the mortgage segment in the 2026 first quarter were 3.1% lower than in the 2025 first quarter, driven by lower U.S. monthly premium business. Net premiums written were flat compared to the 2025 first quarter, reflecting lower cessions on U.S. primary business.

Estimated net favorable development of prior year loss reserves, before related adjustments, decreased the loss ratio by 19.2 points, compared to 20.4 points in the 2025 first quarter. Such amounts were primarily related to better than expected cure rates. The 2026 first quarter loss ratio reflected a modestly higher level of delinquencies than in the 2025 first quarter.

The underwriting expense ratio was 17.0% in the 2026 first quarter, compared to 15.0% in the 2025 first quarter. The increase was primarily due to higher gross acquisition expenses and lower ceding and profit commissions on U.S. primary business. The 2026 first quarter ratio also reflected the impact of a lower level of net premiums earned.

Corporate

The Company's results include net investment income, net realized gains or losses (which include, but are not limited to, realized and unrealized changes in the fair value of equity securities and assets accounted for using the fair value option, realized and unrealized gains and losses on derivative instruments, changes in the allowance for credit losses on financial assets and gains and losses realized from the acquisition or disposition of subsidiaries), equity in net income or loss of investments accounted for using the equity method, other income (loss), corporate benefit (expenses), transaction costs and other, amortization of intangible assets, interest expense, net foreign exchange gains or losses, income tax items, income or loss from operating affiliates and items related to the Company's non-cumulative preferred shares.

Investment returns were as follows:

(1)		Presented on an annualized basis and excluding the impact of investments for which returns are not included within investment income, such as investments accounted for using the equity method and certain equities.
(2)		See ‘Comments on Non-GAAP Financial Measures' for further details.

Net investment income for the 2026 first quarter, compared to the 2025 first quarter, primarily reflected growth in average invested assets, due in part to strong operating cash flows. Net realized losses were $87 million for the 2026 first quarter, compared to net realized gains of $3 million in the 2025 first quarter, and were primarily the result of financial market movements on the Company's derivatives, equity securities and investments accounted for under the fair value option method.

Corporate expenses for the 2026 first quarter were $31 million, compared to $50 million for the 2025 first quarter. Such expenses primarily represent certain holding company costs necessary to support our worldwide operations and costs associated with operating as a publicly traded company. The decline in the 2026 first quarter primarily reflected the benefit of Bermuda qualified refundable tax credits.

Amortization of intangible assets was $30 million for the 2026 first quarter, compared to $49 million for the 2025 first quarter. Both periods reflected the amortization of intangible assets related to the MCE Acquisition.

On a pre-tax basis, net foreign exchange gains were $21 million for the 2026 first quarter, compared to net foreign exchange losses of $27 million for the 2025 first quarter. For both periods, such amounts were primarily unrealized and resulted from the effects of revaluing the Company's net insurance liabilities required to be settled in foreign currencies at each balance sheet date. Changes in the value of available-for-sale investments held in foreign currencies due to foreign currency rate movements are reflected as a direct increase or decrease to shareholders' equity and are not included in the consolidated statements of income.

The Company's effective tax rate on income before income taxes (based on the Company's annual effective tax rate) was 8.6% for the 2026 first quarter, compared to 17.4% for the 2025 first quarter. The decrease in the effective tax rate was primarily driven by tax law changes in Bermuda and the United Kingdom. The Company's effective tax rate on pre-tax operating income available to Arch common shareholders was 14.8% for the 2026 first quarter, compared to 11.7% for the 2025 first quarter. The effective tax rate may fluctuate from period to period based upon the relative mix of income or loss reported by jurisdiction, the level of catastrophic loss activity incurred, and the varying tax rates in each jurisdiction.

Income from operating affiliates for the 2026 first quarter was $36 million, or $0.10 per share, compared to $17 million, or $0.04 per share, for the 2025 first quarter, and primarily reflects amounts related to the Company's investment in Somers Group Holdings Ltd. and Coface SA.

Arch Capital Group Ltd., is a publicly listed Bermuda exempted company with approximately $26.9 billion in capital at March 31, 2026. Arch, which is part of the S&P 500 index, provides insurance, reinsurance and mortgage insurance on a worldwide basis through its wholly owned subsidiaries.

Comments on Non-GAAP Financial Measures

Throughout this release, the Company presents its operations in the way it believes will be the most meaningful and useful to investors, analysts, rating agencies and others who use the Company's financial information in evaluating the performance of the Company and that investors and such other persons benefit from having a consistent basis for comparison between quarters and for comparison with other companies within the industry. These measures may not, however, be comparable to similarly titled measures used by companies outside of the insurance industry. Investors are cautioned not to place undue reliance on these non-GAAP financial measures in assessing the Company's overall financial performance.

This presentation includes the use of "after-tax operating income or loss available to Arch common shareholders," which is defined as net income available to Arch common shareholders, excluding net realized gains or losses (which include, but are not limited to, realized and unrealized changes in the fair value of equity securities and assets accounted for using the fair value option, realized and unrealized gains and losses on derivative instruments, changes in the allowance for credit losses on financial assets and gains and losses realized from the acquisition or disposition of subsidiaries), equity in net income or loss of investments accounted for using the equity method, net foreign exchange gains or losses, transaction costs and other, net of income taxes and the use of annualized operating return on average common equity. The presentation of after-tax operating income available to Arch common shareholders and annualized operating return on average common equity are non-GAAP financial measures as defined in Regulation G. The reconciliation of such measures to net income available to Arch common shareholders and annualized net income return on average common equity (the most directly comparable GAAP financial measures) in accordance with Regulation G is included on page 2 of this release.

The Company believes that net realized gains or losses, equity in net income or loss of investments accounted for using the equity method, net foreign exchange gains or losses and transaction costs and other, in any particular period are not indicative of the performance of, or trends in, the Company's business performance. Although net realized gains or losses, equity in net income or loss of investments accounted for using the equity method and net foreign exchange gains or losses are an integral part of the Company's operations, the decision to realize these items are independent of the insurance underwriting process and result, in large part, from general economic and financial market conditions. Furthermore, certain users of the Company's financial information believe that, for many companies, the timing of the realization of investment gains or losses is largely opportunistic. In addition, changes in the allowance for credit losses and net impairment losses recognized in earnings on the Company's investments represent other-than-temporary declines in expected recovery values on securities without actual realization.

The use of the equity method on certain of the Company's investments in certain funds that invest in fixed maturity securities is driven by the ownership structure of such funds (either limited partnerships or limited liability companies). In applying the equity method, these investments are initially recorded at cost and are subsequently adjusted based on the Company's proportionate share of the net income or loss of the funds (which include changes in the fair value of the underlying securities in the funds). This method of accounting is different from the way the Company accounts for its other fixed maturity securities and the timing of the recognition of equity in net income or loss of investments accounted for using the equity method may differ from gains or losses in the future upon sale or maturity of such investments.

Transaction costs and other include integration, advisory, financing, legal, severance, incentive compensation and all other costs directly related to acquisitions. The Company believes that transaction costs and other, due to their non-recurring nature, are not indicative of the performance of, or trends in, the Company's business performance.

The Company believes that showing net income available to Arch common shareholders exclusive of the items referred to above reflects the underlying fundamentals of the Company's business since the Company evaluates the performance of and manages its business to produce an underwriting profit. In addition to presenting net income available to Arch common shareholders, the Company believes that this presentation enables investors and other users of the Company's financial information to analyze the Company's performance in a manner similar to how the Company's management analyzes performance. The Company also believes that this measure follows industry practice and, therefore, allows the users of the Company's financial information to compare the Company's performance with its industry peer group. The Company believes that the equity analysts and certain rating agencies that follow the Company and the insurance industry as a whole generally exclude these items from their analyses for the same reasons.

The Company's segment information includes the presentation of consolidated underwriting income or loss and a subtotal of underwriting income or loss. Such measures represent the pre-tax profitability of its underwriting operations and include net premiums earned plus other underwriting income, less losses and loss adjustment expenses, acquisition expenses and other operating expenses. Other operating expenses include those operating expenses that are incremental and/or directly attributable to the Company's individual underwriting operations. Underwriting income or loss does not include certain income and expense items which are included in corporate. While these measures are presented in the Segment Information footnote to the Company's Consolidated Financial Statements, they are considered non-GAAP financial measures when presented elsewhere on a consolidated basis. The reconciliations of underwriting income or loss to income before income taxes (the most directly comparable GAAP financial measure) on a consolidated basis, in accordance with Regulation G, is shown on the following pages.

Management measures segment performance for its three underwriting segments based on underwriting income or loss. The Company does not manage its assets by underwriting segment and, accordingly, investment income, income from operating affiliates and other items are not allocated to each underwriting segment.

In addition, the Company's segment information includes the use of a combined ratio excluding catastrophic activity and prior year development, for the insurance and reinsurance segments, and a combined ratio excluding prior year development, for the mortgage segment. These ratios are non-GAAP financial measures as defined in Regulation G. The reconciliation of such measures to the combined ratio (the most directly comparable GAAP financial measure) in accordance with Regulation G are shown on the individual segment pages. The Company's management utilizes the adjusted combined ratios excluding current accident year catastrophic events and favorable or adverse development in prior year loss reserves in its analysis of the underwriting performance of each of its underwriting segments. Effective in the 2025 first quarter, the ‘Other operating expense ratio' includes ‘Other underwriting income.'

Total return on investments includes investment income, equity in net income or loss of investments accounted for using the equity method, net realized gains and losses (excluding changes in the allowance for credit losses on non-investment related financial assets) and the change in unrealized gains and losses generated by Arch's investment portfolio. Total return is calculated on a pre-tax basis and before investment expenses and reflects the effect of financial market conditions along with foreign currency fluctuations. Management uses total return on investments as a key measure of the return generated to Arch common shareholders, and compares the return generated by the Company's investment portfolio against benchmark returns during the periods presented.

The following tables summarize the Company's results by segment for the 2026 first quarter and 2025 first quarter and a reconciliation of underwriting income or loss to income or loss before income taxes and net income or loss available to Arch common shareholders:

Forward-looking statements involve the Company's current assessment of risks and uncertainties. Actual events and results may differ materially from those expressed or implied in these statements.

claims for natural catastrophic events or severe economic events in the Company's insurance, reinsurance and mortgage businesses could cause large losses and substantial volatility in the Company's results of operations;
availability to the Company of reinsurance to manage our net exposures and the cost of such reinsurance;
the failure of reinsurers, managing general agents, third party administrators or others to meet their obligations to the Company;
the timing of loss payments being faster or the receipt of reinsurance recoverables being slower than anticipated by the Company;

the effect of contagious diseases or a pandemic on the Company's business;
