Presentation represents a "non-GAAP" financial measure as defined in Regulation G. Such presentation excludes the results of Somers Group Holdings Ltd. ("Somers"), formerly known as Watford Holdings Ltd., which the Company consolidated in its financial statements through June 30, 2021 pursuant to GAAP. See ‘Comments on Regulation G' for further details.

Segment Information

The following section provides analysis on the Company's 2022 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, 2022. 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

Underwriting Ratios					% Point Change
Loss ratio		57.1%		63.1%	(6.0)
Underwriting expense ratio		34.0%		31.2%	2.8
Combined ratio		91.1%		94.3%	(3.2)

Catastrophic activity and prior year development:
Current accident year catastrophic events, net of reinsurance and reinstatement premiums		1.5%		3.2%	(1.7)
Net (favorable) adverse development in prior year loss reserves, net of related adjustments		(0.4)%		(0.3)%	(0.1)
Combined ratio excluding catastrophic activity and prior year development		90.0%		91.4%	(1.4)

Gross premiums written by the insurance segment in the 2022 second quarter were 24.6% higher than in the 2021 second quarter while net premiums written were 27.5% higher than in the 2021 second quarter. The higher level of net premiums written reflected increases in most lines of business, due in part to rate increases, new business opportunities and growth in existing accounts. Net premiums earned in the 2022 second quarter were 27.4% higher than in the 2021 second quarter, and reflect changes in net premiums written over the previous five quarters.

The 2022 second quarter loss ratio reflected 1.2 points of current year catastrophic activity, compared to 3.2 points of catastrophic activity in the 2021 second quarter. Estimated net favorable development of prior year loss reserves, before related adjustments, reduced the loss ratio by 0.6 points in the 2022 second quarter, compared to 0.5 in the 2021 second quarter. The improvement in the 2022 second quarter loss ratio also reflected the impact of rate increases and changes in mix of business.

The underwriting expense ratio was 34.0% in the 2022 second quarter, compared to 31.2% in the 2021 second quarter. The increase in the 2022 second quarter was primarily due to higher gross commission ratios, growth in lines with higher acquisition costs, such as travel, and targeted personnel expansion to support our growth. This increase was partially offset by a higher level of net premiums earned.

Reinsurance Segment

Underwriting expense ratio		27.5%		24.2%	3.3
Combined ratio		85.4%		87.1%	(1.7)

Catastrophic activity and prior year development:
Current accident year catastrophic events, net of reinsurance and reinstatement premiums		7.1%		2.5%	4.6
Net (favorable) adverse development in prior year loss reserves, net of related adjustments		(4.5)%		(2.5)%	(2.0)
Combined ratio excluding catastrophic activity and prior year development		82.8%		87.1%	(4.3)

Gross premiums written by the reinsurance segment in the 2022 second quarter were 32.1% higher than in the 2021 second quarter, while net premiums written were 25.7% higher than in the 2021 second quarter. The growth in net premiums written reflected increases in other specialty, property catastrophe and property excluding property catastrophe lines, primarily related to rate increases, new business opportunities and growth in existing accounts. Net premiums earned by the reinsurance segment in the 2022 second quarter were 25.9% higher than in the 2021 second quarter, and reflect changes in net premiums written over the previous five quarters.

The 2022 second quarter loss ratio reflected 7.5 points of current year catastrophic activity, primarily due to a series of natural events outside the U.S., compared to 2.6 points of catastrophic activity in the 2021 second quarter. Estimated net favorable development of prior year loss reserves, before related adjustments, reduced the loss ratio by 5.0 points in the 2022 second quarter, compared to 2.8 points in the 2021 second quarter. The improvement in the 2022 second quarter loss ratio also reflected the impact of rate increases and changes in mix of business.

The underwriting expense ratio was 27.5% in the 2022 second quarter, compared to 24.2% in the 2021 second quarter, with the increase primarily resulting from growth in lines with higher acquisition costs and targeted personnel expansion to support our growth. This increase was partially offset by a higher level of net premiums earned.

Mortgage Segment

(U.S. dollars in thousands)		2022		2021	% Change

Gross premiums written	$	371,896	$	391,511	(5.0)

Combined ratio excluding prior year development		39.2%		39.6%	(0.4)

Gross premiums written by the mortgage segment in the 2022 second quarter were 5.0% lower than in the 2021 second quarter, while net premiums written were 12.5% lower. The reduction in gross premiums written primarily reflected lower U.S. primary mortgage insurance single premium volume and a decrease in monthly premiums. Net premiums written for the 2022 second quarter reflected a higher level of premiums ceded than in the 2021 second quarter, while the reduction in net premiums earned also reflected a lower level of earnings from single premium policy terminations and a decline in monthly premiums.

Estimated net favorable development of prior year loss reserves, before related adjustments, reduced the loss ratio by 39.9 points, primarily related to the U.S. first lien portfolio from the 2020 accident year, compared to 12.9 points in the 2021 second quarter. The percentage of loans in default on U.S. primary mortgage insurance business was 1.77% at June 30, 2022, compared to 2.09% at March 31, 2022. The 2022 second quarter loss ratio also reflected the lower level of net premiums earned in the U.S. primary mortgage insurance business.

The underwriting expense ratio was 20.4% in the 2022 second quarter, compared to 23.5% in the 2021 second quarter, with the decrease primarily due to lower acquisition expenses on Australian mortgage insurance following the acquisition of Westpac LMI in the 2021 third quarter and profit commissions on business ceded related to favorable development of prior year loss reserves. Such amounts were partially offset by a lower level of net premiums earned in the U.S. primary mortgage insurance business.

Corporate Segment

The corporate segment results include net investment income, 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, 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. Such amounts exclude the results of the ‘other' segment.

Pre-tax net investment income for the 2022 second quarter was $0.28 per share, or $106.4 million, reflecting the effects of higher interest rates available in the market, compared to $0.21 per share, or $80.4 million, for the 2022 first quarter, and $0.22 per share, or $89.4 million, for the 2021 second quarter. The annualized pre-tax investment income yield was 1.76% for the 2022 second quarter, compared to 1.34% for the 2022 first quarter and 1.47% for the 2021 second quarter. Total return, a non-GAAP measure, was -3.02% for the 2022 second quarter, compared to -3.07% for the 2022 first quarter and 1.58% for the 2021 second quarter. Total return for the 2022 periods primarily reflected the impact of rising interest rates. See ‘Comments on Regulation G' for a discussion of non-GAAP financial measures.

Net realized gains or losses reflect sales of investments along with the impact of financial market movements on the Company's investment portfolio, including 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. On a pre-tax basis, net realized losses for the 2022 second quarter were $266.6 million, which included $109.9 million of mark-to-market losses on equity securities, compared to net realized gains of $163.4 million for the 2021 second quarter.

Interest expense for the 2022 second quarter was $32.8 million, compared to $31.4 million for the 2021 second quarter, and primarily reflects amounts related to the Company's outstanding senior notes.

On a pre-tax basis, net foreign exchange gains for the 2022 second quarter were $87.8 million, compared to net foreign exchange losses for the 2021 second quarter of $17.9 million. 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. Although the Company generally attempts to match the currency of its projected liabilities with investments in the same currencies, the Company may elect to over or underweight one or more currencies from time to time, which could increase the Company's exposure to foreign currency fluctuations and increase the volatility of the Company's shareholders' equity.

The Company's effective tax rate on income before income taxes (based on the Company's estimated annual effective tax rate) was 5.2% for the 2022 second quarter, compared to 7.0% for the 2021 second quarter. The Company's effective tax rate on pre-tax operating income available to Arch common shareholders was 5.7% for the 2022 second quarter, compared to 7.6% for the 2021 second quarter. The Company's 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 2022 second quarter was $4.6 million, or $0.01 per share, compared to $24.5 million, or $0.06 per share, for the 2021 second quarter, and primarily reflects amounts related to Company's investment in Somers and Coface SA.

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 and loss on redemption of preferred shares, 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, transaction costs and other and loss on redemption of preferred shares 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 investment gains or losses, the recognition of the change in the carrying value of investments accounted for using the fair value option in net realized gains or losses, the recognition of equity in net income or loss of investment funds accounted for using the equity method and the recognition of foreign exchange gains or losses 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. The loss on redemption of preferred shares related to the redemption of the Company's Series E preferred shares in September 2021 had no impact on shareholders' equity or cash flows. 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 which 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 before the contribution from the ‘other' segment. 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 and a subtotal before the contribution from the ‘other' segment, 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. As noted earlier, the ‘other' segment includes the results of Somers through June 30, 2021.

Along with consolidated underwriting income, the Company provides a subtotal of underwriting income or loss before the contribution from the ‘other' segment and believes that this presentation enables investors and other users of the Company's financial information to analyze the Company's underwriting performance in a manner similar to how the Company's management analyzes performance. Pursuant to GAAP, Somers was considered a variable interest entity and the Company concluded that it was the primary beneficiary of Somers through June 30, 2021. As such, the Company consolidated the results of Somers in its consolidated financial statements. The Company's presentation of information on a ‘core' basis enabled 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 analyzed performance. In the 2020 fourth quarter, Arch, Somers, and Greysbridge Ltd., a wholly-owned subsidiary of Arch ("Greysbridge"), entered into an Agreement and Plan of Merger (as amended, the "Merger Agreement"). The merger and the related Greysbridge equity financing closed on July 1, 2021. Effective July 1, 2021, Somers is wholly owned by Greysbridge and Greysbridge is owned 40% by the Company, 30% by certain investment funds managed by Kelso & Company and 30% by certain investment funds managed by Warburg Pincus LLC. Based on the governing documents of Greysbridge, the Company has concluded that, while it retains significant influence over Greysbridge, Greysbridge does not constitute a variable interest entity. Accordingly, effective July 1, 2021, Arch no longer consolidates the results of Somers in its consolidated financial statements and footnotes.

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, excludes amounts reflected in the ‘other' segment, 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 2022 second quarter and 2021 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;
the Company's ability to successfully enhance, integrate and maintain operating procedures (including information technology) to effectively support its current and new business;
the loss and addition of key personnel;
material differences between actual and expected assessments for guaranty funds and mandatory pooling arrangements;
accuracy of those estimates and judgments utilized in the preparation of the Company's financial statements, including those related to revenue recognition, insurance and other reserves, reinsurance recoverables, investment valuations, intangible assets, bad debts, income taxes, contingencies and litigation, and any determination to use the deposit method of accounting;
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;
availability to the Company of reinsurance to manage its gross and 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 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;
changes in the method for determining the London Inter-bank Offered Rate ("LIBOR") and the replacement of LIBOR with alternative benchmark rates;
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;
statutory or regulatory developments, including as to tax policy matters and insurance and other regulatory matters such as the adoption of proposed legislation that would affect Bermuda-headquartered companies and/or Bermuda-based insurers or reinsurers and/or changes in regulations or tax laws applicable to the Company, its subsidiaries, brokers or customers, including new guidance implementing the Tax Cuts and Jobs Act of 2017 and the possible implementation of the Organization for Economic Cooperation and Development ("OECD") Pillar I and Pillar II initiative; and
the other matters set forth under Item 1A "Risk Factors", Item 7 "Management's Discussion and Analysis of Financial Condition and Results of Operations" and other sections of the Company's Annual Report on Form 10-K, as well as the other factors set forth in the Company's other documents on file with the SEC, and management's response to any of the aforementioned factors.

All subsequent written and oral forward-looking statements attributable to the Company or persons acting on its behalf are expressly qualified in their entirety by these cautionary statements. The foregoing review of important factors should not be construed as exhaustive and should be read in conjunction with other cautionary statements that are included herein or elsewhere.
