The following section provides analysis on the Company's 2023 second quarter performance by operating segment. For additional details regarding the Company's operating segments, please refer to the Company's Financial Supplement dated June 30, 2023. The Company's segment information includes the use of underwriting income (loss) and a combined ratio excluding catastrophic activity and prior year development. Such items are non-GAAP financial measures (see ‘Comments on Regulation G' for further details).

Insurance Segment

Combined ratio excluding catastrophic activity and prior year development		89.8	%		90.0	%	(0.2	)

Gross premiums written by the insurance segment in the 2023 second quarter were 14.7% higher than in the 2022 second quarter, while net premiums written were 18.4% higher than in the 2022 second quarter. Growth in net premiums written reflected increases in most lines of business, due in part to new business opportunities, increases in existing accounts and rate changes. In addition, the insurance segment retained more business in the 2023 second quarter than in the 2022 second quarter. Net premiums earned in the 2023 second quarter were 20.5% higher than in the 2022 second quarter, and reflect changes in net premiums written over the previous five quarters.

The 2023 second quarter loss ratio reflected 2.7 points of current year catastrophic activity, spread across a series of global events, compared to 1.2 points of catastrophic activity in the 2022 second quarter. Estimated net favorable development of prior year loss reserves, before related adjustments, reduced the loss ratio by 0.9 points in the 2023 second quarter, compared to 0.6 points in the 2022 second quarter. The improvement in the 2023 second quarter loss ratio also reflected the impact of rate increases and changes in mix of business.

The underwriting expense ratio was 34.6% in the 2023 second quarter, compared to 34.0% in the 2022 second quarter, reflecting higher acquisition expenses primarily due to lower ceding commissions received and changes in mix of business.

Reinsurance Segment

Gross premiums written	$	2,544		$	1,793		41.9

Catastrophic activity and prior year development:

Net (favorable) adverse development in prior year loss reserves, net of related adjustments		(1.8	)%		(4.5	)%	2.7
Combined ratio excluding catastrophic activity and prior year development		77.4	%		82.8	%	(5.4	)

Gross premiums written by the reinsurance segment in the 2023 second quarter were 41.9% higher than in the 2022 second quarter, while net premiums written were 46.9% higher than in the 2022 second quarter. Growth in net premiums written primarily reflected increases in property catastrophe, property excluding property catastrophe and other specialty lines, due in part to rate increases, new business opportunities and growth in existing accounts. In addition, the 2023 second quarter net premiums written reflected a lower level of retrocession activity than in the 2022 second quarter. Net premiums earned in the 2023 second quarter were 44.7% higher than in the 2022 second quarter, and reflect changes in net premiums written over the previous five quarters.

The 2023 second quarter loss ratio reflected 6.7 points of current year catastrophic activity, spread across a series of global events, compared to 7.5 points of catastrophic activity in the 2022 second quarter. Estimated net favorable development of prior year loss reserves, before related adjustments, reduced the loss ratio by 2.2 points in the 2023 second quarter, compared to 5.0 points in the 2022 second quarter. The improvement in the 2023 second quarter loss ratio also reflected the impact of rate increases and changes in mix of business.

The underwriting expense ratio was 26.6% in the 2023 second quarter, compared to 27.5% in the 2022 second quarter, with the decrease primarily due to growth in net premiums earned.

Mortgage Segment

Gross premiums written	$	347		$	372		(6.7	)

Combined ratio excluding prior year development		43.7	%		39.2	%	4.5

Gross premiums written by the mortgage segment in the 2023 second quarter were 6.7% lower than in the 2022 second quarter, while net premiums written were 9.9% lower than in the 2022 second quarter. The reduction in gross premiums written primarily reflected lower originations in the Australian market and a decrease in U.S. primary mortgage insurance business, which was partially offset by a higher volume of credit risk transfer transactions. Net premiums written for the 2023 second quarter reflected a higher level of ceded premiums through quota share reinsurance agreements than in the 2022 second quarter. Net premiums earned in the 2023 second quarter were 0.7% lower than in the 2022 second quarter, primarily due to higher ceded premiums and a decrease in U.S. primary mortgage insurance business, which was partially offset by the growth in credit risk transfer and international business.

Estimated net favorable development of prior year loss reserves, before related adjustments, decreased the loss ratio by 27.2 points, primarily related to the U.S. first lien portfolio from the 2021 and 2022 accident years, compared to 39.9 points in the 2022 second quarter. Such amounts were primarily related to better than expected cure rates in the 2020 through 2022 accident years. The 2023 second quarter loss ratio also reflected a higher level of new delinquencies than in the 2022 second quarter.

The underwriting expense ratio was 19.5% in the 2023 second quarter, compared to 20.4% in the 2022 second quarter. The decrease was primarily due to higher profit commissions on ceded U.S. primary mortgage insurance business.

Corporate Segment

The corporate segment results include net investment income, net realized gains or losses (which includes 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 and changes in the allowance for credit losses on financial assets), equity in net income or loss of investment funds accounted for using the equity method, other income (loss), corporate expenses, transaction costs and other, amortization of intangible assets, interest expense, net foreign exchange gains or losses, income taxes 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)	Presentation represents a "non-GAAP" financial measure as defined in Regulation G. See ‘Comments on Regulation G' for further details.

The growth in net investment income in the 2023 second quarter primarily reflected the effects of higher interest rates available in the market along with growth in invested assets which benefited from strong operating cash flows. Net realized losses were $123 million for the 2023 second quarter, compared to losses of $267 million in the 2022 second quarter, and reflected sales of investments as well as the impact of financial market movements on the Company's equity securities and investments accounted for under the fair value option method.

On a pre-tax basis, net foreign exchange losses for the 2023 second quarter were $5 million, compared to net foreign exchange gains of $88 million for the 2022 second 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 estimated annual effective tax rate) was 9.2% for the 2023 second quarter, compared to 5.2% for the 2022 second quarter. The Company's effective tax rate on pre-tax operating income available to Arch common shareholders was 8.0% for the 2023 second quarter, compared to 5.7% for the 2022 second 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 2023 second quarter was $22 million, or $0.06 per share, compared to $5 million, or $0.01 per share, for the 2022 second 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 $17.4 billion in capital at June 30, 2023. 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 Regulation G

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 includes changes in the allowance for credit losses on financial assets and net impairment losses recognized in earnings), equity in net income or loss of investment funds 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 investment funds 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 investment funds 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 investment funds 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 advisory, financing, legal, severance, incentive compensation and other costs 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.

Due to these reasons, the Company excludes net realized gains or losses, equity in net income or loss of investment funds accounted for using the equity method, net foreign exchange gains or losses and transaction costs and other from the calculation of after-tax operating income or loss available to Arch common shareholders.

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 incorporate items included in the Company's corporate segment. 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 corporate segment related 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.

Total return on investments includes investment income, equity in net income or loss of investment funds 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 2023 second quarter and 2022 second 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:

Cautionary Note Regarding Forward-Looking Statements

The Private Securities Litigation Reform Act of 1995 ("PSLRA") provides a "safe harbor" for forward-looking statements. This release or any other written or oral statements made by or on behalf of the Company may include forward-looking statements, which reflect the Company's current views with respect to future events and financial performance. All statements other than statements of historical fact included in or incorporated by reference in this release are forward-looking statements. Forward-looking statements, for purposes of the PSLRA or otherwise, can generally be identified by the use of forward-looking terminology such as "may," "will," "expect," "intend," "estimate," "anticipate," "believe" or "continue" and similar statements of a future or forward-looking nature or their negative or variations or similar terminology.

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. Important factors that could cause actual events or results to differ materially from those indicated in such statements are discussed below and elsewhere in this release and in the Company's periodic reports filed with the Securities and Exchange Commission (the "SEC"), and include:

the Company's ability to successfully implement its business strategy during "soft" as well as "hard" markets;
acceptance of the Company's business strategy, security and financial condition by rating agencies and regulators, as well as by brokers and its insureds and reinsureds;
the Company's ability to consummate acquisitions and integrate any businesses it has acquired or may acquire into its existing operations;
the Company's ability to maintain or improve its ratings, which may be affected by its ability to raise additional equity or debt financings, by ratings agencies' existing or new policies and practices, as well as other factors described herein;
general economic and market conditions (including inflation, interest rates, unemployment, housing prices, foreign currency exchange rates, prevailing credit terms and the depth and duration of a recession, including those resulting from COVID-19) and conditions specific to the reinsurance and insurance markets in which the Company operates;
competition, including increased competition, on the basis of pricing, capacity (including alternative sources of capital), coverage terms or other factors;
developments in the world's financial and capital markets and the Company's access to such markets;

greater than expected loss ratios on business written by the Company and adverse development on claim and/or claim expense liabilities related to business written by its insurance and reinsurance subsidiaries;
the adequacy of the Company's loss reserves;
severity and/or frequency of losses;
greater frequency or severity of unpredictable natural and man-made catastrophic events;
claims resulting from natural or man-made 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;
the effect of climate change on the Company's business;
the effect of contagious diseases (including COVID-19) on the Company's business;
acts of terrorism, political unrest and other hostilities or other unforecasted and unpredictable events;

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 Company's investment performance, including legislative or regulatory developments that may adversely affect the fair value of the Company's investments;
changes in general economic conditions, including new or continued sovereign debt concerns or downgrades of U.S. securities by credit rating agencies, which could affect the Company's business, financial condition and results of operations;
the volatility of the Company's shareholders' equity from foreign currency fluctuations, which could increase due to us not matching portions of the Company's projected liabilities in foreign currencies with investments in the same currencies;
changes in accounting principles or policies or in the Company's application of such accounting principles or policies;
changes in the political environment of certain countries in which the Company operates, underwrites business or invests;
a disruption caused by cyber-attacks or other technology breaches or failures on the Company or the Company's business partners and service providers, which could negatively impact the Company's business and/or expose the Company to litigation;
