NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

1.    Basis of Presentation and Recent Accounting Pronouncements
General
Arch Capital Group Ltd. (“Arch Capital”) is a publicly listed Bermuda exempted company which provides insurance, reinsurance and mortgage insurance on a worldwide basis through its wholly-owned subsidiaries. As used herein, the “Company” and/or “Arch” means Arch Capital and its subsidiaries.
Basis of Presentation
The interim consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”). All significant intercompany transactions and balances have been eliminated in consolidation. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ materially from those estimates and assumptions. In the opinion of management, the accompanying unaudited interim consolidated financial statements reflect all adjustments (consisting of normally recurring accruals) necessary for a fair statement of results on an interim basis. The results of any interim period are not necessarily indicative of the results for a full year or any future periods. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted; however, management believes that the disclosures are adequate to make the information presented not misleading. This report should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2025 (“2025 Form 10-K”), including the Company’s audited consolidated financial statements and related notes.
The Company has reclassified the presentation of certain prior year information to conform to the current presentation. Such reclassifications had no effect on the Company’s net income, comprehensive income, shareholders’ equity or cash flows. All amounts are in millions, except per share amounts, unless otherwise noted.
Recent Accounting Pronouncements
Recently Issued Accounting Standards Adopted
The Company early adopted ASU 2025-06, “Intangibles—Goodwill and Other—Internal–Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software,” which was issued in September 2025, and applied the guidance prospectively. The new guidance amended the accounting for internal-use software by eliminating references to software development project stages. Under the revised standard, entities must capitalize software costs when (i) management has authorized and committed funding for the project, and (ii) it is probable that the project will be completed and the software will function as intended. The update also clarifies that both internal and external training costs, as well as maintenance costs, must be expensed as incurred. The adoption of this ASU did not have a material impact on the Company’s consolidated financial statements and related disclosures.
For information regarding additional accounting standards that the Company has not yet adopted, see note 3(u), “Significant Accounting Policies—Recent Accounting Pronouncements,” of the notes to consolidated financial statements in the Company’s 2025 Form 10-K.

2.    Acquisition
On August 1, 2024, the Company completed the acquisition of the U.S MidCorp and Entertainment insurance business from Allianz (“MCE Acquisition”). This business is written by Fireman’s Fund Insurance Company, an affiliate of Allianz, and its subsidiaries (collectively, the “Business Entities”), in each case, relating to relevant policies with accident years 2016 and onwards (collectively, the “Business”), as well as certain assets of Allianz and its affiliates related to the Business. In connection with the acquisition of the Business, the Company also entered into certain reinsurance agreements relating to the Business and the Business Entities and other agreements providing for administration and other services for the Business Entities by the Company for the applicable policies being reinsured following the closing. The acquisition of the Business is an important part of the Company’s growth strategy, and provides a ballast to our existing insurance business. It further enhances the Company’s capabilities in the U.S. middle markets and represents an attractive way to enter a new niche entertainment insurance market.
Aggregate cash consideration for the transaction was $450 million. Direct costs related to the acquisition are immaterial, and were expensed as incurred. These include one-time costs that are directly attributable to third party consulting fees and other professional and legal fees related to the acquisition. Such costs are included within ‘corporate expenses’ in the consolidated statement of income. The Business acquired is included within the Company’s insurance segment beginning from the acquisition date.
The MCE Acquisition was accounted for as a business combination under FASB Accounting Standards Codification Topic 805, Business Combinations (“Topic 805”). Pursuant to Topic 805, the Company allocated the MCE Acquisition purchase price to tangible and identifiable intangible assets acquired and liabilities assumed based on their estimated fair values as of the acquisition date. The excess of the purchase price over those fair values was recorded to goodwill. During the measurement period, the Company adjusted the provisional amounts to reflect new information obtained about facts and circumstances that existed as of the Acquisition Date, which, if known, would have affected the measurement of the amounts recognized as of that date. Such adjustments impacted certain identifiable assets acquired and liabilities assumed, resulting in a decrease to net assets acquired and a corresponding increase to goodwill of $10 million. The Company completed the analysis of the fair value of the assets, liabilities assumed and the related allocation of the purchase price during the 2025 second quarter.

The following table summarizes the Company’s allocation of the purchase price to the acquired assets and liabilities assumed based on estimated fair values on August 1, 2024.
Total Useful Life
Purchase price
Cash paid (a) $ 450 
Assets Acquired

Total assets acquired $ 3,296 
Liabilities Acquired
Reserves for losses and loss adjustment expenses $ 2,468 
Unearned premiums 636
Other liabilities acquired 18
Total liabilities acquired 3,122 
Identifiable net assets acquired (b) $ 174 
Goodwill (a) - (b) $ 276 
(1)    Includes $130 million related to the net fair value adjustment to reserves for loss and loss adjustment expenses on August 1, 2024.
The Company recognized goodwill of $276 million that is primarily attributed to the expanded presence and long-term growth opportunities in the insurance market provided by this strategic acquisition. Approximately $555 million of the acquired goodwill and intangibles is expected to be deductible for income tax purposes. At the date of the acquisition, the Company established a net deferred tax asset of $24 million related to the estimated fair value of reserves for losses and loss adjustment expenses and unearned premiums.
Intangible assets resulting from the acquisition are amortized as part of ‘amortization of intangible assets’ in the Company’s consolidated statements of income. The significant fair value adjustments and related future amortization are as follows:
Value of business acquired (“VOBA”)— which represents the present value of the expected underwriting profit within the unearned premium liability, less costs to service the related policies and a risk premium. The fair value of VOBA was determined after taking into consideration certain key assumptions, including the estimated cost of capital, investment yield, loss ratio and related expenses.

ARCH CAPITAL GROUP LTD. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)
Reserves for losses and loss adjustment expenses—to reflect a decrease related to the present value of the reserve for losses and loss adjustment expenses based on the estimated payout patterns, partially offset by an increase in losses and loss adjustment expenses related to the estimated market based risk margin. The risk margin represents the estimated costs of capital required by a market participant to assume the losses and loss adjustment expenses. The fair value of the reserve for losses and loss adjustment expenses was determined after taking into consideration certain key assumptions, including the estimated cost of capital, and investment yield.
Distribution relationships—the value of the distribution relationships was determined after taking into consideration certain key assumptions, including the estimated cost of capital, investment yield, retention rates, loss ratios, related expenses and effective tax rates that would impact the expected cash flows from Business policies written on a go forward basis.
The results of the acquired Business have been included in the Company’s consolidated financial statements beginning as of their acquisition date. It is impracticable to provide historical supplemental pro forma financial information along with revenue and earnings subsequent to the acquisition due to a variety of factors, including access to historical information and the operations of acquirees being integrated within the Company shortly after closing and not operating as discrete operations within the Company’s organizational structure.
3.    Share Transactions
Share-Based Compensation
During the 2026 first quarter, the Company granted 0.4 million stock options, 0.6 million performance share awards and performance share units (“PSAs/PSUs”) and 0.8 million restricted shares and units to certain employees. The stock options were valued at the grant date using the Black-Scholes option pricing model. The weighted average grant-date fair value of the stock options, PSAs/PSUs and restricted shares and units granted during the 2026 first quarter were $35.11, $106.15 and $100.30 per share, respectively.

Share Repurchases
The Board of Directors of Arch Capital has authorized the investment in Arch Capital’s common shares through a share repurchase program. Since the inception of the share repurchase program, Arch Capital has repurchased 463 million common shares for an aggregate purchase price of $8.6 billion. For the three months ended March 31, 2026, Arch Capital repurchased 8.3 million common shares under the share repurchase program with an aggregate purchase price of approximately $783 million.

At March 31, 2026, $324 million of share repurchases were available under the program.
On April 19, 2026, the Company increased its authorization for its existing share repurchase program by $3.0 billion, which as in the past, may be effected from time to time in open market or privately negotiated transactions. The timing and amount of the repurchase transactions under this program will depend on a variety of factors, including market conditions and corporate and regulatory considerations.
From April 1 through May 1, 2026, the Company repurchased approximately 3.6 million common shares for an aggregate purchase price of $346 million. As of May 1, 2026, approximately $3.0 billion of repurchases were available under the Company’s share repurchase program. See note 17.

5.    Segment Information
The Company’s insurance, reinsurance and mortgage segments each have managers who are responsible for the overall profitability of their respective segments and who are directly accountable to the Company’s chief operating decision makers (“CODMs”), the Chief Executive Officer of Arch Capital and the Chief Financial Officer and Treasurer of Arch Capital. The CODMs do not assess performance, measure return on equity or make resource allocation decisions on a line of business basis. Management measures segment performance for its three segments based on underwriting income or loss. The Company does not manage its assets by segment, with the exception of goodwill and intangible assets and accordingly investment income is not allocated to each underwriting segment.
The Company has determined its segments using the management approach described in accounting guidance regarding disclosures about segments of an enterprise and related information. The accounting policies of the segments are the same as those used for the preparation of the Company’s consolidated financial statements. Intersegment business is allocated to the segment accountable for the underwriting results.
The Company’s insurance segment primarily consists of commercial insurance lines of business, with a focus on specialty insurance products. These products are mainly offered in North America, Bermuda, the United Kingdom, continental Europe and Australia. Products offered in North America include: commercial automobile; commercial multi‐peril; other liability—claims made, which includes financial and professional lines; other liability—occurrence, which includes admitted and excess and surplus casualty lines; property and short-tail specialty; workers compensation; and other. Products offered across the Company’s International units include: property and short-tail specialty; and casualty and other.
The Company’s reinsurance segment offers reinsurance products on a worldwide basis. Product lines of business include: casualty; marine and aviation; property catastrophe; property excluding property catastrophe; specialty; and other.
The Company’s mortgage segment consists of U.S. primary mortgage insurance business written predominantly on loans sold to the Federal National Mortgage Association (“Fannie Mae”) and the Federal Home Loan Mortgage Corporation (“Freddie Mac”), each a government sponsored entity (“GSE”) and also through non GSE approved entities (combined “Arch MI U.S.”); reinsurance and underwriting services related to U.S. credit-risk transfer (“CRT”) business which are predominately with the GSEs and other U.S. mortgage reinsurance transactions; and international mortgage insurance and reinsurance business covering loans primarily in Australia and Europe.
The Company’s results also 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 or losses on derivative instruments, changes in the allowance for credit losses on financial assets and gains or 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 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.

2026 First Quarter
The insurance segment’s short-tailed lines included $10 million of favorable development in travel and accident, primarily from the 2024 and 2025 accident years (i.e., the year in which a loss occurred). Long-tailed lines primarily included favorable development in casualty business, primarily from the 2022 and 2023 accident years.
The reinsurance segment’s short-tailed lines included $72 million of favorable development from property other than property catastrophe business, primarily from the 2023 to 2025 underwriting years (i.e., all premiums and losses attributable to contracts having an inception or renewal date within the given 12 month period), and $63 million of favorable development from specialty business, primarily from the 2025 underwriting year. Long-tailed lines included $20 million of adverse development in casualty, primarily from the 2022 to 2024 underwriting year.
The mortgage segment’s favorable development was driven by reductions on reserves for delinquent loans associated with the U.S. first lien portfolio primarily from the 2024 and 2025 accident years, with the credit risk transfer and international businesses also contributing.
2025 First Quarter
The insurance segment’s short-tailed lines included $8 million of favorable development in property and marine, primarily from the 2024 accident year, and $8 million of favorable development in travel and accident, primarily from the 2023 accident year. Long tailed lines included favorable development in executive assurance, from the 2022 and prior accident years, partially offset by adverse development in programs, mainly from the 2024 accident year.
The reinsurance segment’s short-tailed lines included $64 million of favorable development from property catastrophe, primarily from the 2023 and 2024 underwriting years, and $35 million of favorable development from specialty lines, primarily from the 2021 to 2024 underwriting years. Long-tailed lines included $8 million of adverse development in casualty, primarily from the 2021 to 2024 underwriting years.
The mortgage segment’s favorable development was driven by reductions on reserves for delinquent loans associated with the U.S. first lien portfolio from the 2023 and 2024 accident years, with the credit risk transfer and international businesses also contributing.

Certain of the Company’s other investments are in investment funds for which the Company has the option to redeem at agreed upon values as described in each investment fund’s subscription agreement. Depending on the terms of the various subscription agreements, investments in investment funds may be redeemed daily, monthly, quarterly or on other terms. Two common redemption restrictions that may impact the Company’s ability to redeem these investment funds are gates and lockups. A gate is a suspension of redemptions that may be implemented by the general partner or investment manager

of the fund in order to defer, in whole or in part, the redemption request in the event the aggregate amount of redemption requests exceeds a predetermined percentage of the investment fund’s net assets and which may otherwise hinder the general partner or investment manager’s ability to liquidate holdings in an orderly fashion in order to generate the cash necessary to fund extraordinarily large redemption payouts. A lockup period is the initial amount of time an investor is contractually required to hold the security before having the ability to redeem. If the investment funds are eligible to be redeemed, the time to redeem such fund can take weeks or months following the notification.
Limited Partnership Interests
In the normal course of its activities, the Company invests in limited partnerships as part of its overall investment strategy. Such amounts are included in ‘investments accounted for using the equity method’ and ‘investments accounted for using the fair value option.’ The Company has determined that it is not required to consolidate these investments because it is not the primary beneficiary of the funds. The Company’s maximum exposure to loss with respect to these investments is limited to the investment carrying amounts reported in the Company’s consolidated balance sheet and any unfunded commitment.
The following table summarizes investments in limited partnership interests where the Company has a variable interest by balance sheet line item:
March 31,

(2)    Aggregate unfunded commitments were $163 million at March 31, 2026, compared to $65 million at December 31, 2025.
Equity in Net Income (Loss) of Investments Accounted for Using the Equity Method
Income from investment funds accounted for using the equity method for the 2026 first quarter was $160 million, compared to $53 million for the 2025 first quarter. In applying the equity method, 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 market value of the underlying securities in the funds). Such investments are generally recorded on a one to three month lag based on the availability of reports from the investment funds.
Investments in Operating Affiliates
Investments in which the Company has significant influence over the operating and financial policies are classified as ‘investments in operating affiliates’ on the Company’s balance sheets and are accounted for under the equity method. Such investments primarily include the Company’s investment in Coface SA (“Coface”), Greysbridge Holdings Ltd. (“Greysbridge”), and Premia Holdings Ltd. Investments in Coface and Premia Holdings Ltd. are generally recorded on a three month lag, while the Company’s investment in Greysbridge is not recorded on a lag.
As of March 31, 2026, the Company owned approximately 29.9% of the issued shares of Coface, or 30% excluding treasury shares, with a carrying value of $718 million, compared to $707 million at December 31, 2025.
As of March 31, 2026, the Company owned 30% of Greysbridge with a carrying value of $502 million, compared to $486 million at December 31, 2025.
Income from operating affiliates for the 2026 first quarter was $36 million, compared to $17 million for the 2025 first quarter.

9.    Fair Value
Accounting guidance regarding fair value measurements addresses how companies should measure fair value when they are required to use a fair value measure for recognition or disclosure purposes under GAAP and provides a common definition of fair value to be used throughout GAAP. It defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly fashion between market participants at the measurement date. In addition, it establishes a three-level valuation hierarchy for the disclosure of fair value measurements. The valuation hierarchy is based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date. The level in the hierarchy within which a given fair value measurement falls is determined based on the lowest level input that is significant to the measurement (Level 1 being the highest priority and Level 3 being the lowest priority).
The levels in the hierarchy are defined as follows:
Level 1:
Inputs to the valuation methodology are observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets
Level 2:
 Inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument
Level 3:
Inputs to the valuation methodology are unobservable and significant to the fair value measurement
The following is a description of the valuation methodologies used for securities measured at fair value, as well as the general classification of such securities pursuant to the valuation hierarchy. The Company reviews its securities measured at fair value and discusses the proper classification of such investments with investment advisers and others.
The Company determines the existence of an active market based on its judgment as to whether transactions for the financial instrument occur in such market with sufficient frequency and volume to provide reliable pricing information. The independent pricing sources obtain market quotations and actual transaction prices for securities that have quoted prices in active markets. The Company uses quoted values and other data provided by nationally recognized independent pricing sources as inputs into its process for determining fair values of its fixed maturity
investments. To validate the techniques or models used by pricing sources, the Company's review process includes, but is not limited to: (i) quantitative analysis (e.g., comparing the quarterly return for each managed portfolio to its target benchmark, with significant differences identified and investigated); (ii) a review of the average number of prices obtained in the pricing process and the range of resulting fair values; (iii) initial and ongoing evaluation of methodologies used by outside parties to calculate fair value; (iv) a comparison of the fair value estimates to the Company’s knowledge of the current market; (v) a comparison of the pricing services' fair values to other pricing services' fair values for the same investments; and (vi) periodic back-testing, which includes randomly selecting purchased or sold securities and comparing the executed prices to the fair value estimates from the pricing service. A price source hierarchy was maintained in order to determine which price source would be used (i.e., a price obtained from a pricing service with more seniority in the hierarchy will be used over a less senior one in all cases). The hierarchy prioritizes pricing services based on availability and reliability and assigns the highest priority to index providers. Based on the above review, the Company will challenge any prices for a security or portfolio which are considered not to be representative of fair value. The Company did not adjust any of the prices obtained from the independent pricing sources at March 31, 2026.
In certain circumstances, when fair values are unavailable from these independent pricing sources, quotes are obtained directly from broker-dealers who are active in the corresponding markets. Such quotes are subject to the validation procedures noted above. Where quotes are unavailable, fair value is determined by the investment manager using quantitative and qualitative assessments such as internally modeled values. Of the $40.6 billion of financial assets and liabilities measured at fair value at March 31, 2026, approximately $311 million, or 0.8%, were priced using non-binding broker-dealer quotes or modeled valuations. Of the $40.3 billion of financial assets and liabilities measured at fair value at December 31, 2025, approximately $278 million, or 0.7%, were priced using non-binding broker-dealer quotes or modeled valuations.

Fixed maturities
The Company uses the market approach valuation technique to estimate the fair value of its fixed maturity securities, when possible. The market approach includes obtaining prices from independent pricing services, such as index providers and pricing vendors, as well as to a lesser extent quotes from broker-dealers. The independent pricing sources obtain market quotations and actual transaction prices for securities that have quoted prices in active markets. Each source has its own proprietary method for determining the fair value of securities that are not actively traded. In general, these methods involve the use of “matrix pricing” in which the independent pricing source uses observable market inputs including, but not limited to, investment yields, credit risks and spreads, benchmarking of like securities, broker-dealer quotes, reported trades and sector groupings to determine a reasonable fair value.
The following describes the significant inputs generally used to determine the fair value of the Company’s fixed maturity securities by asset class:
U.S. government and government agencies – valuations provided by independent pricing services, with all prices provided through index providers and pricing vendors. The Company determined that all U.S. Treasuries would be classified as Level 1 securities due to observed levels of trading activity, the high number of strongly correlated pricing quotes received on U.S. Treasuries and other factors. The fair values of U.S. government agency securities are generally determined using the spread above the risk-free yield curve. As the yields for the risk-free yield curve and the spreads for these securities are observable market inputs, the fair values of U.S. government agency securities are classified within Level 2.
Corporate bonds – valuations provided by independent pricing services, substantially all through index providers and pricing vendors with a small amount through broker-dealers. The fair values of these securities are generally determined using the spread above the risk-free yield curve. These spreads are generally obtained from the new issue market, secondary trading and from broker-dealers who trade in the relevant security market. As the significant inputs used in the pricing process for corporate bonds are observable market inputs, the fair value of these securities are classified within Level 2. A small number of securities are included in Level 3 due to a low level of transparency on the inputs used in the pricing process.
Municipal bonds – valuations provided by independent pricing services, with all prices provided through index providers and pricing vendors. The fair values of these securities are generally determined using spreads obtained from broker-dealers who trade in the relevant security market, trade prices and the new issue market. As the
significant inputs used in the pricing process for municipal bonds are observable market inputs, the fair value of these securities are classified within Level 2.
Residential mortgage-backed securities – valuations provided by independent pricing services, substantially all through pricing vendors and index providers with a small amount through broker-dealers. The fair values of these securities are generally determined through the use of pricing models (including Option Adjusted Spread) which use spreads to determine the expected average life of the securities. These spreads are generally obtained from the new issue market, secondary trading and from broker-dealers who trade in the relevant security market. The pricing services also review prepayment speeds and other indicators, when applicable. As the significant inputs used in the pricing process for mortgage-backed securities are observable market inputs, the fair value of these securities are classified within Level 2. A small number of securities are included in Level 3 due to a low level of transparency on the inputs used in the pricing process.
Commercial mortgage-backed securities – valuations provided by independent pricing services, substantially all through index providers and pricing vendors with a small amount through broker-dealers. The fair values of these securities are generally determined through the use of pricing models which use spreads to determine the appropriate average life of the securities. These spreads are generally obtained from the new issue market, secondary trading and from broker-dealers who trade in the relevant security market. The pricing services also review prepayment speeds and other indicators, when applicable. As the significant inputs used in the pricing process for commercial mortgage-backed securities are observable market inputs, the fair value of these securities are classified within Level 2.
Non-U.S. government securities – valuations provided by independent pricing services, with all prices provided through index providers and pricing vendors. The fair values of these securities are generally based on international indices or valuation models which include daily observed yield curves, cross-currency basis index spreads and country credit spreads. As the significant inputs used in the pricing process for non-U.S. government securities are observable market inputs, the fair value of these securities are classified within Level 2.
Asset-backed securities – valuations provided by independent pricing services, substantially all through index providers and pricing vendors with a small amount through broker-dealers. The fair values of these securities are generally determined through the use of pricing models (including Option Adjusted Spread) which use spreads to determine the appropriate average life of the securities. These spreads are generally obtained from the new issue

market, secondary trading and from broker-dealers who trade in the relevant security market. The pricing services also review prepayment speeds and other indicators, when applicable. As the significant inputs used in the pricing process for asset-backed securities are observable market inputs, the fair value of these securities are classified within Level 2.
Equity securities
The Company determined that exchange-traded equity securities would be included in Level 1 as their fair values are based on quoted market prices in active markets. Certain equity securities are included in Level 2 of the valuation hierarchy as the significant inputs used in the pricing process for such securities are observable market inputs. Other equity securities are included in Level 3 due to the lack of an available independent price source for such securities. As the significant inputs used to price these securities are unobservable, the fair value of such securities are classified as Level 3.
Other investments
The Company’s other investments include term loan investments for which fair values are estimated by using quoted prices of term loan investments with similar characteristics, pricing models or matrix pricing. Such investments are generally classified within Level 2. The fair values for certain of the Company’s other investments are determined using net asset values as advised by external fund managers. The net asset value is based on the fund manager’s valuation of the underlying holdings in accordance with the fund’s governing documents. In accordance with applicable accounting guidance, certain investments that are measured at fair value using the net asset value per share (or its equivalent) practical expedient have not been classified in the fair value hierarchy. A small number of securities are included in Level 3 due to the lack of an available independent price source for such securities.
Derivative instruments
The Company’s futures contracts, foreign currency forward contracts, interest rate swaps and other derivatives trade in the over-the-counter derivative market. The Company uses the market approach valuation technique to estimate the fair value for these derivatives based on significant observable market inputs from third party pricing vendors, non-binding broker-dealer quotes and/or recent trading activity. As the significant inputs used in the pricing process for these derivative instruments are observable market inputs, the fair value of these securities are classified within Level 2.

Short-term investments
The Company determined that certain of its short-term investments held in highly liquid money market-type funds, U.S. Treasury bills and commercial paper would be included in Level 1 as their fair values are based on quoted market prices in active markets. The fair values of certain short-term investments are generally determined using the spread above the risk-free yield curve and are classified within Level 2. Other short-term investments are included in Level 3 due to the lack of an available independent price source for such securities. As the significant inputs used to price these short-term securities are unobservable, the fair value of such securities are classified as Level 3.
Residential mortgage loans
The Company’s residential mortgage loans (included in ‘other assets’ in the consolidated balance sheets) include amounts related to the Company’s whole mortgage loan purchase and sell program. Fair values of residential mortgage loans are generally determined based on market prices. As significant inputs used in the pricing process for these residential mortgage loans are observable market inputs, the fair value of these securities are classified within Level 2.
Other liabilities
The Company’s other liabilities include contingent and deferred consideration liabilities related to the Company’s acquisitions. Contingent consideration liabilities are remeasured at fair value at each balance sheet date with changes in fair value recognized in ‘net realized gains (losses’). To determine the fair value of contingent consideration liabilities, the Company estimates the future payments using an income approach based on modeled inputs which include a weighted average cost of capital. Deferred consideration liabilities are measured at fair value on the transaction date. The Company determined that contingent and deferred consideration liabilities would be included within Level 3.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)
Financial Instruments Disclosed, But Not Carried, At Fair Value
The Company uses various financial instruments in the normal course of its business. The carrying values of cash, accrued investment income, receivable for securities sold, certain other assets, payable for securities purchased and certain other liabilities approximated their fair values at March 31, 2026, due to their respective short maturities. As these financial instruments are not actively traded, their respective fair values are classified within Level 2.
At March 31, 2026, the Company’s senior notes were carried at their cost, net of debt issuance costs, of $2.7 billion and had a fair value of $2.4 billion. At December 31, 2025, the Company’s senior notes were carried at their cost, net of debt issuance costs, of $2.7 billion and had a fair value of $2.5 billion. The fair values of the senior notes were obtained from a third party pricing service and are based on observable market inputs. As such, the fair values of the senior notes are classified within Level 2.
10.    Derivative Instruments
The Company’s investment strategy allows for the use of derivative instruments. The Company’s derivative instruments are recorded on its consolidated balance sheets at fair value. The Company utilizes exchange traded U.S. Treasury notes, Eurodollar and other futures contracts and commodity futures to manage portfolio duration or replicate investment positions in its portfolios and the Company routinely utilizes foreign currency forward contracts, currency options, index futures contracts and other derivatives as part of its total return objective. In addition, certain of the Company’s investments are managed in portfolios which incorporate the use of foreign currency forward contracts which are intended to provide an economic hedge against foreign currency movements. 
From time to time, the Company purchases to-be-announced mortgage backed securities (“TBAs”) as part of its investment strategy. TBAs represent commitments to purchase a future issuance of agency mortgage backed securities. For the period between purchase of a TBA and issuance of the underlying security, the Company’s position is accounted for as a derivative. The Company purchases TBAs in both long and short positions to enhance investment performance and as part of its overall investment strategy.
The following table summarizes information on the fair values and notional values of the Company’s derivative instruments:

(3)    Includes swaps, options and other derivatives contracts.

The Company did not hold any derivatives that were designated as hedging instruments at March 31, 2026 or December 31, 2025.
The Company’s derivative instruments can be traded under master netting agreements, which establish terms that apply to all derivative transactions with a counterparty. In the event of a bankruptcy or other stipulated event of default, such agreements provide that the non-defaulting party may elect to terminate all outstanding derivative transactions, in which case all individual derivative positions (loss or gain) with a counterparty are closed out and netted and replaced with a single amount, usually referred to as the termination amount, which is expressed in a single currency. The resulting single net amount, where positive, is payable to the party “in-the-money” regardless of whether or not it is the defaulting party, unless the parties have agreed that only the non-defaulting party is entitled to receive a termination payment where the net amount is positive and is in its favor. Contractual close-out netting reduces derivative credit exposure from gross to net exposure.
At March 31, 2026, asset derivatives and liability derivatives of $287 million and $171 million, respectively, were subject to a master netting agreement, compared to $180 million and $72 million, respectively, at December 31, 2025.

Investment Commitments
The Company’s investment commitments, which are primarily related to agreements entered into by the Company to invest in funds and separately managed accounts when called upon, were approximately $3.9 billion at March 31, 2026, compared to $3.7 billion at December 31, 2025.
12.    Variable Interest Entities
Bellemeade Re
The Company has entered into aggregate excess of loss mortgage reinsurance agreements with various special purpose reinsurance companies domiciled in Bermuda (the “Bellemeade Agreements”). At the time the Bellemeade Agreements were entered into, the applicability of the accounting guidance that addresses VIEs was evaluated. As a result of the evaluation of the Bellemeade Agreements, the Company concluded that these entities are VIEs. However, given that the ceding insurers do not have the unilateral power to direct those activities that are significant to their economic performance, the Company does not consolidate such entities in its consolidated financial statements. The reinsurance premium paid in regard to the Bellemeade Agreements is calculated by multiplying the outstanding reinsurance coverage amount at the beginning of the period by the coupon rate, which is the SOFR plus a contractual risk margin, less the actual investment income collected during the preceding month on the assets included in the underlying reinsurance trusts. In the event the assets included in the underlying reinsurance trusts became severely impaired or worthless and the special purpose reinsurance companies were unable to meet their future obligations, the Company’s mortgage insurance subsidiaries would be liable to fulfill claim payments to policyholders. The Company’s maximum exposure to loss associated with these VIEs is determined as the amount of mortgage insurance claim payments on the insured policies, net of aggregate reinsurance payments previously received, up to the full aggregate excess of loss reinsurance coverage amounts.
The following table summarizes the total assets of the Bellemeade entities:

14.    Income Taxes
The Company’s income tax provision on income before income taxes, including income (loss) from operating affiliates, resulted in an effective tax rate of 8.6% for the three months ended March 31, 2026, compared to 17.4% for the three months ended March 31, 2025. 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, which is based upon the expected annual effective tax rate, may fluctuate from period to period based on the relative mix of income or loss reported by jurisdiction and the varying tax rates in each jurisdiction.
The Company had a net deferred tax asset of $1.4 billion at March 31, 2026, consistent with a net deferred tax asset of $1.4 billion at December 31, 2025. In addition, the Company paid $22 million of income taxes for the three months ended March 31, 2026, compared to $18 million of income taxes paid for the three months ended March 31, 2025.
15.    Legal Proceedings
The Company, in common with the insurance industry in general, is subject to litigation and arbitration in the normal course of its business. As of March 31, 2026, the Company was not a party to any litigation or arbitration which is expected by management to have a material adverse effect on the Company’s results of operations and financial condition and liquidity.
16.    Transactions with Related Parties
Premia Reinsurance Ltd. is a multi-line Bermuda reinsurance company (and its affiliates together with Premia Holdings Ltd., “Premia”). The Company has entered into certain reinsurance transactions with Premia. During the three months ended March 31, 2026 and 2025, the Company did not enter into any new reinsurance transactions with Premia. At March 31, 2026, the Company recorded a funds held asset from Premia of $119 million, compared to $124 million at December 31, 2025.
Somers Group Holdings Ltd. and its wholly owned subsidiaries (collectively, “Somers”) are wholly owned by Greysbridge. For the three months ended March 31, 2026, the Company’s net premiums written was reduced by $143 million, compared to $216 million for the three months ended March 31, 2025, as a result of certain reinsurance transactions with Somers. In addition, Somers paid certain acquisition costs and administrative fees to the Company. At March 31, 2026, the Company recorded a reinsurance recoverable on unpaid and paid losses from Somers of $2.0 billion and a reinsurance balance payable to Somers of $549 million, compared to $2.0 billion and $550 million, respectively, at December 31, 2025.
Pursuant to the terms of the Greysbridge shareholder agreement, as amended, following the expiration of a specified period, Arch Capital has a call right (but not the obligation) and certain third party investors have put rights (but not the obligation) to purchase or sell, as applicable, a specified amount of each such investor’s initial common shares on an annual basis at Greysbridge’s year-end book value per share. Obligations under put/call option notices are recognized on the Company’s balance sheet in both other assets and other liabilities. At March 31, 2026, the Company’s balance sheet included $186 million in both other assets and other liabilities for such put notices. Transactions related to the put shares are expected to close in the 2026 calendar year, subject to any regulatory approval.
17.    Subsequent Event
Share Repurchases
On April 19, 2026, the Company increased its authorization for its existing share repurchase program by $3.0 billion, which, as in the past, may be effected from time to time in open market or privately negotiated transactions. After taking into account this increased authorization and share repurchases effected after the close of the 2026 first quarter, approximately $3.0 billion of share repurchases were available under the program as of May 1, 2026. The timing and amount of the repurchase transactions under this program will depend on a variety of factors, including market conditions and corporate and regulatory considerations.

CURRENT OUTLOOK
We delivered a strong 2026 first quarter, with attractive underwriting margins reflecting the disciplined execution of our underwriting and capital management strategies. For the quarter, we generated an annualized net income return on average common equity and an annualized operating return on average common equity of 17.8% and 15.4%, respectively. See “Comment on Non-GAAP Financial Measures.” Critical to our cycle management is emphasizing risk selection, as we continue to leverage our diversified specialty platform and the expertise of our underwriting teams. We invest and use data and analytics to sharpen insights, enhance risk selection and deliver a differentiated customer experience while fostering a culture that attracts the best-in-class talent. We believe our balance sheet is in excellent health, giving us optionality as we remain prudent stewards of the capital entrusted to us by our shareholders. Our strong balance sheet permits us to both invest in our business and return capital to investors. During the 2026 first quarter, we repurchased $783 million of Arch common shares.
Market conditions have become more competitive compared to recent years; however, rates and terms and conditions, in aggregate, continue to support attractive returns. Capturing those returns requires the ability and willingness to actively manage the portfolio across and within lines of business. We continue to execute our cycle management strategy by actively allocating capital to the segments with the best risk-adjusted returns, while retaining the flexibility to invest in our platform when we find attractive opportunities.
Our insurance segment reported $66 million of underwriting income for the 2026 first quarter. Overall, market conditions remained favorable; however, topline growth in the segment was essentially flat, reflecting a focus on profitability over volume as competitive pressures persist. Growth opportunities remained across most casualty-focused lines of business, including E&S casualty, construction and alternative markets in the U.S., as well as select lines of our London market business. These opportunities were partially offset by competitive rate pressure in select property and short‑tail lines, as well as our decision not to renew certain middle market commercial program business we acquired from Allianz in 2024 (the “MCE Acquisition”). We have substantially completed the data and system migration of the acquired businesses, positioning the platform to pursue scalable growth and enhance client and distribution experience. Operating expenses were elevated this quarter as we incurred additional expenses related to the transition of the MCE Acquisition, with certain remaining transition expenses expected to extend into mid‑year.
Our reinsurance segment contributed $441 million of underwriting income in the 2026 first quarter, benefiting from disciplined underwriting and a favorable portfolio mix. Net premiums written were $2.2 billion, down roughly 6% when compared to 2025 first quarter, reflecting pricing pressures and higher retentions by cedants in certain property and short‑tail lines. As increased capacity has contributed to competitive conditions across portions of the reinsurance market, our underwriting teams are working to actively manage the cycle by selectively writing new business where returns are attractive and reduce participation where pricing does not meet our minimum return thresholds.
Our mortgage segment continued to deliver a steady level of earnings, generating $221 million of underwriting income in the 2026 first quarter. New originations remained modest due to affordability challenges tied to mortgage rates and home prices, which continued to constrain demand. We believe the underlying fundamentals of our mortgage portfolio remain strong, and our U.S. market share was stable. The persistency of our in-force U.S. primary mortgage insurance portfolio remained a healthy 80.7%, and our delinquency rate remained low. We continue to expect the mortgage segment to serve as a steady diversifying contributor to our overall earnings and generate attractive underwriting income given the high credit quality and embedded equity of our in-force portfolio.

FINANCIAL MEASURES
Management uses the following three key financial indicators in evaluating our performance and measuring the overall growth in value generated for Arch Capital’s common shareholders:
Book Value per Share
Book value per share represents total common shareholders’ equity available to Arch divided by the number of common shares outstanding. Management uses growth in book value per share as a key measure of the value generated for our common shareholders each period and believes that book value per share is the key driver of Arch Capital’s share price over time. Book value per share is impacted by, among other factors, our underwriting results, investment returns and share repurchase activity, which has an accretive or dilutive impact on book value per share depending on the purchase price. Book value per share was $66.19 at March 31, 2026, compared to $65.11 at December 31, 2025, and $55.15 at March 31, 2025. The 1.7% increase in book value per share for the 2026 first quarter primarily reflected strong underwriting returns.
Operating Return on Average Common Equity
Operating return on average common equity (“Operating ROAE”) represents annualized after-tax operating income available to Arch common shareholders divided by the average of beginning and ending common shareholders’ equity available to Arch during the period. After-tax operating income available to Arch common shareholders, a non-GAAP financial measure as defined in Regulation G, represents 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 or losses on derivative instruments, changes in the allowance for credit losses on financial assets and gains or 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 and income taxes. Management uses Operating ROAE as a key measure of the return generated to common shareholders. See “Comment on Non-GAAP Financial Measures.”
Our annualized net income return on average common equity was 17.8% for the 2026 first quarter, compared to 11.1% for the 2025 first quarter. Our Operating ROAE was 15.4% for the 2026 first quarter, compared to 11.5% for the 2025 first quarter. Return for the 2026 periods reflected strong underwriting returns.
Total Return on Investments
Total return on investments, a non-GAAP financial measure as defined in Regulation G, includes investment income, equity in net income or loss of investments accounted for using the equity method, net realized gains or losses attributable to the investment portfolio and the change in unrealized gains or 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. In addition, total return incorporates the timing of investment returns during the periods. The following table summarizes our total return compared to the benchmark return against which we measured our portfolio during the periods. See “Comment on Non-GAAP Financial Measures.”

Return
Pre-tax total return (before investment expenses):
2026 First Quarter 0.10  % 0.01  %
2025 First Quarter 2.02  % 2.04  %
Total return for the 2026 first quarter reflected the impact of higher interest rates on our fixed income portfolio. We continue to maintain a relatively short duration on our fixed income portfolio of 3.43 years at March 31, 2026, in line with our asset allocation targets.
The benchmark return index is a customized combination of indices intended to approximate a target portfolio by asset mix and average credit quality with a fixed income component matching the approximate estimated duration and currency mix of our insurance and reinsurance liabilities. It is recalibrated annually. Although the estimated fixed income duration and average credit quality of this index will move as the duration and rating of its constituent securities change, generally we do not adjust the composition of the benchmark return index during the year except to incorporate changes to the mix of liability currencies and durations noted above. The benchmark return index should not be interpreted as expressing a preference for or aversion to any particular sector or sector weight. At March 31, 2026, the fixed income portion of the benchmark had an average credit quality of “A1” by Moody’s and an estimated fixed income duration of 3.17 years.

COMMENT ON NON-GAAP FINANCIAL MEASURES
Throughout this filing, we present our operations in the way we believe will be the most meaningful and useful to investors, analysts, rating agencies and others who use our financial information in evaluating the performance of our company. This presentation includes the use of after-tax operating income 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 or losses on derivative instruments, changes in the allowance for credit losses on financial assets and gains or 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, 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 under “Results of Operations” below.
We believe 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, our business. 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 our 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 our 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 our investments represent other-than-temporary declines in expected recovery values on securities without actual realization. Furthermore, we exclude net realized gains or losses from the acquisition or disposition of subsidiaries, due to their non-recurring nature, such items are not indicative of the performance of, or trends in, our business performance.
The use of the equity method on certain of our investments 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 our proportionate share of the net income or loss of the funds (which include changes in the market value of the underlying securities in the funds). This method of accounting is different from the way in which we account for our other investments; 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 transaction costs directly related to acquisitions. We believe that transaction costs and other, due to their nonrecurring nature, are not indicative of the performance of, or trends in, our business performance.

We believe that showing net income available to Arch common shareholders exclusive of the items referred to above reflects the underlying fundamentals of our business since we evaluate the performance of and manage our business to produce an underwriting profit. In addition to presenting the net income available to Arch common shareholders, we believe that this presentation enables investors and other users of our financial information to analyze our performance in a manner similar to how management analyzes performance. We also believe that this measure follows industry practice and, therefore, allows the users of financial information to compare our performance with our industry peer group. We believe that the equity analysts and certain rating agencies that follow us and the insurance industry as a whole generally exclude these items from their analyses for the same reasons.
Our segment information includes the presentation of consolidated underwriting income or loss. Such measures represent the pre-tax profitability of our 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 our individual underwriting operations. Underwriting income or loss does not incorporate certain income and expense items which are included in corporate. While these measures are presented in note 5, “Segment Information,” to our 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 in note 5, “Segment Information” to our consolidated financial statements.
We measure segment performance for our three underwriting segments based on underwriting income or loss. We do not manage our assets by underwriting segment, with the exception of goodwill and intangible assets, and, accordingly, investment income, income from operating affiliates and other non-underwriting related items are not allocated to each underwriting segment.
Our presentation of segment information includes the use of a current year loss ratio which excludes favorable or adverse development in prior year loss reserves. This ratio is a non-GAAP financial measure as defined in Regulation G. The reconciliation of such measure to the loss ratio (the most directly comparable GAAP financial measure) in accordance with Regulation G is shown on the individual segment pages. Management utilizes the current year loss ratio in its analysis of the underwriting performance of each of our 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 or losses (excluding net realized gains or losses on non-investment related financial assets) and the change in unrealized gains or 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. In addition, total return incorporates the timing of investment returns during the periods. There is no directly comparable GAAP financial measure for total return. Management uses total return on investments as a key measure of the return generated to Arch common shareholders on the capital held in the business, and compares the return generated by our investment portfolio against benchmark returns which we measured our portfolio against during the periods.

Segment Information
We classify our businesses into three underwriting segments: insurance, reinsurance and mortgage. Our insurance, reinsurance and mortgage segments each have managers who are responsible for the overall profitability of their respective segments and who are directly accountable to our chief operating decision makers (“CODMs”), the Chief Executive Officer of Arch Capital and the Chief Financial Officer and Treasurer of Arch Capital. The CODMs do not assess performance, measure return on equity or make resource allocation decisions on a line of business basis. Management measures segment performance for our three underwriting segments based on underwriting income or loss. We do not manage our assets by underwriting segment, with the exception of goodwill and intangible assets and accordingly investment income is not allocated to each underwriting segment.
We determined our reportable segments using the management approach described in accounting guidance regarding disclosures about segments of an enterprise and related information. The accounting policies of the segments are the same as those used for the preparation of our consolidated financial statements. Intersegment business is allocated to the segment accountable for the underwriting results.
Insurance Segment
The Company’s insurance segment primarily consists of commercial insurance lines of business, with a focus on specialty insurance products. These products are mainly offered in North America, Bermuda, the United Kingdom, continental Europe and Australia. Products offered in North America include: commercial automobile; commercial multi-peril; other liability-claims made, which includes financial and professional lines; other liability-occurrence, which includes admitted and excess and surplus casualty lines; property and short-tail specialty; workers compensation; and other. Products offered across the Company’s International units include: property and short-tail specialty; and casualty and other.

2026 First Quarter versus 2025 Period. The insurance segment’s current year loss ratio in the 2026 first quarter was 6.0 points lower than in the 2025 first quarter. 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.

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

Underwriting Expenses.
2026 First Quarter versus 2025 Period. The underwriting expense ratio for the mortgage segment 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 mortgage business. The 2026 first quarter ratio also reflected the impact of a lower level of net premiums earned.
Corporate
The Company’s corporate 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 or losses on derivative instruments, changes in the allowance for credit losses on financial assets and gains or 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 or loss, corporate expenses, transaction costs and other, amortization of intangible assets, interest expense, net foreign exchange gains or losses, income taxes, income from operating affiliates and items related to our non-cumulative preferred shares.
Net Investment Income.
The components of net investment income were derived from the following sources:

Fixed maturities $ 384  $ 342 
Short-term investments 24  26 
Equity securities (dividends) 8  11 
Other (1) 21  28 
Gross investment income 437  407 
Investment expenses (2) (29) (29)
Net investment income $ 408  $ 378 
(1)    Amounts include dividends and other distributions on investment funds, term loan investments, funds held balances, cash balances and other items.
(2)        Investment expenses were approximately 0.29% of average invested assets for the 2026 first quarter, compared to 0.32% for the 2025 first quarter.
The higher level of net investment income for the 2026 period primarily reflected growth in average invested assets, due in part to strong operating cash flows. Net cash flow from operating activities contributed $1.2 billion for the three months ended March 31, 2026. The pre-tax investment income yield, calculated based on amortized cost and on an annualized basis, was 3.99% for the 2026 first quarter, compared to 4.16% for the 2025 first quarter.
Corporate Expenses.
Corporate expenses were $31 million for the 2026 first quarter, compared to $50 million for the 2025 first quarter. Such amounts 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.
Transaction Costs and Other.
Transaction costs and other for the 2026 first quarter was $18 million, compared to $10 million for the 2025 first quarter. Amounts in both periods primarily includes direct costs related to the MCE Acquisition.
Other Income or Losses.
Other income for the 2026 first quarter was a loss of $5 million, compared to a loss of $2 million for the 2025 first quarter. Amounts in both periods primarily reflect changes in the cash surrender value of our investment in corporate-owned life insurance.
Amortization of Intangible Assets.
Amortization of intangible assets for the 2026 first quarter was $30 million, compared to $49 million for the 2025 first quarter. Amounts in both periods reflected the amortization of intangible assets related to the MCE Acquisition.
Interest Expense.
Interest expense was $37 million for the 2026 first quarter, compared to $35 million for the 2025 first quarter. Interest expense primarily reflects amounts related to our outstanding senior notes.
Net Realized Gains or Losses.
Net realized losses for the 2026 first quarter were $87 million, compared to net realized gains of $3 million for the 2025 first quarter. Amounts in both periods 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. Currently, our portfolio is actively managed to maximize total return within certain guidelines. The effect of financial market movements on the investment portfolio will directly impact net realized gains or losses as the portfolio is adjusted and rebalanced. Net realized gains or losses from the sale of fixed maturities primarily results from our decisions to reduce credit exposure, to change duration targets, to rebalance our portfolios or due to relative value determinations.

Net realized gains or losses also 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 or losses on derivative instruments, changes in the allowance for credit losses on financial assets and gains or losses realized from the acquisition or disposition of subsidiaries. See note 8, “Investment Information—Net Realized Gains (Losses)” and note 8, “Investment Information—Allowance for Expected Credit Losses,” to our consolidated financial statements for additional information.
Equity in Net Income or Losses of Investments Accounted for Using the Equity Method.
Equity in net income of investments accounted for using the equity method was $160 million in the 2026 first quarter, compared to $53 million for the 2025 first quarter. Such investments are generally recorded on a one to three month lag based on the availability of reports from the investment funds. Investment funds accounted for using the equity method totaled $6.7 billion at March 31, 2026, compared to $6.5 billion at December 31, 2025. See note 8, “Investment Information—Investments Accounted For Using the Equity Method,” to our consolidated financial statements for additional information.
Net Foreign Exchange Gains or Losses.
Net foreign exchange gains for the 2026 first quarter were $21 million, compared to losses of $27 million for the 2025 first quarter. Amounts in both periods were primarily unrealized and resulted from the effects of revaluing our net insurance liabilities required to be settled in foreign currencies at each balance sheet date.
Income Tax Expense.
Our income tax provision on income or loss before income taxes, including income or loss from operating affiliates, resulted in an expense of 8.6% for the 2026 first quarter, compared to an expense of 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. See note 14, “Income Taxes” to our consolidated financial statements for additional information.
Income or Losses from Operating Affiliates.
Income from operating affiliates for the 2026 first quarter was $36 million, compared to income of $17 million for the 2025 first quarter. Such amounts primarily related to the Company’s investment in Somers Group Holdings Ltd. (“Somers”) and Coface SA. See note 8, “Investment Information—Investments in Operating Affiliates,” to our consolidated financial statements for additional information.

For details on our investments accounted for using the equity method, see note 8, “Investment Information—Investments Accounted For Using the Equity Method,” to our consolidated financial statements.
Our investment strategy allows for the use of derivative instruments. We utilize various derivative instruments such as futures contracts to enhance investment performance, replicate investment positions or manage market exposures and duration risk that would be allowed under our investment guidelines if implemented in other ways. See note 10, “Derivative Instruments,” to our consolidated financial statements for additional disclosures related to derivatives.
Accounting guidance regarding fair value measurements addresses how companies should measure fair value when they are required to use a fair value measure for recognition or disclosure purposes under GAAP and provides a common definition of fair value to be used throughout GAAP. See note 9, “Fair Value,” to our consolidated financial statements for a summary of our financial assets and liabilities measured at fair value, segregated by level in the fair value hierarchy.

See note 7, “Allowance for Expected Credit Losses,” to our consolidated financial statements for information about our reinsurance recoverables and related allowance for credit losses.
Bellemeade Re
We have entered into aggregate excess of loss mortgage reinsurance agreements with various special purpose reinsurance companies domiciled in Bermuda (the “Bellemeade Agreements”). For the respective coverage periods, we will retain the first layer of the respective aggregate losses and the special purpose reinsurance companies will provide second layer coverage up to the outstanding coverage amount. We will then retain losses in excess of the outstanding coverage limit. The aggregate excess of loss reinsurance coverage generally decreases over a ten-year period as the underlying covered mortgages amortize, unless provisional call options embedded within certain of the Bellemeade Agreements are executed or if pre-defined delinquency triggering events occur.

Reserve for Losses and Loss Adjustment Expenses 
We establish reserve for losses and loss adjustment expenses (“Loss Reserves”) which represent estimates involving actuarial and statistical projections, at a given point in time, of our expectations of the ultimate settlement and administration costs of losses incurred. Estimating Loss Reserves is inherently difficult. We utilize actuarial models as well as available historical insurance industry loss ratio experience and loss development patterns to assist in the establishment of Loss Reserves. Actual losses and loss adjustment expenses paid will deviate, perhaps substantially, from the reserve estimates reflected in our financial statements.
At March 31, 2026 and December 31, 2025, our Loss Reserves, net of unpaid losses and loss adjustment expenses recoverable, by type and by operating segment were as follows:

LIQUIDITY
Liquidity is a measure of our ability to access sufficient cash flows to meet the short-term and long-term cash requirements of our business operations.
Arch Capital is a holding company whose assets primarily consist of shares in its subsidiaries. Generally, Arch Capital depends on its available cash resources, liquid investments and dividends or other distributions from its subsidiaries to make payments, including the payment of debt service obligations and operating expenses it may incur and any dividends or liquidation amounts with respect to our preferred and common shares.
For the three months ended March 31, 2026, Arch Capital received dividends of $690 million from Arch Reinsurance Ltd. (“Arch Re Bermuda”), our Bermuda based reinsurer and insurer, which can pay approximately $5.7 billion to Arch Capital during the remainder of 2026 without providing an affidavit to the Bermuda Monetary Authority.
We expect that our liquidity needs, including our anticipated (re)insurance obligations and operating and capital expenditure needs, for the next 12 months and for the foreseeable future thereafter, will be met by funds generated from underwriting activities and investment income, as well as by our balance of cash, short-term investments, proceeds on the sale or maturity of our investments, and our credit facilities.
Cash Flows
The following table summarizes our cash flows from operating, investing and financing activities:

Cash provided by operating activities for the three months ended March 31, 2026 was lower than in the 2025 period. Activity for the three months ended March 31, 2026 primarily reflected a lower level of premium collected than in the 2025 period.
Cash used for investing activities for the three months ended March 31, 2026 was lower than in the 2025 period. Activity for the three months ended March 31, 2026 reflected lower net purchases of investments than in the 2025 period, due in part to a higher level of repurchases under our share repurchase program than in the 2025 period.
Cash used for financing activities for the three months ended March 31, 2026 was higher than in the 2025 period, primarily due to the higher level of repurchases under our share repurchase program. We repurchased approximately $783 million of our common shares in the 2026 period, compared to $196 million in the 2025 period.

Arch MI U.S. is required to maintain compliance with the GSEs requirements, known as the Private Mortgage Insurer Eligibility Requirements or “PMIERs.” The financial requirements require an eligible mortgage insurer’s available assets, which generally include only the most liquid assets of an insurer, to meet or exceed “minimum required assets” as of each quarter end. Minimum required assets are calculated from PMIERs tables with several risk dimensions (including origination year, original loan-to-value and original credit score of performing loans, and the delinquency status of non-performing loans) and are subject to a minimum amount. Arch MI U.S. satisfied the PMIERs’ financial requirements with an estimated PMIERs sufficiency ratio of 175% at March 31, 2026, compared to 179% at December 31, 2025. On August 21, 2024, Fannie Mae and Freddie Mac each updated their PMIERs to incorporate new deductions to available assets for investment risk. This update became effective on March 31, 2025, but the impact will be phased in through September 30, 2026. If the GSEs had fully implemented this update to PMIERs as of March 31, 2026, the changes would have reduced the available assets by 2% and resulted in a pro-forma PMIERs sufficiency ratio of 173%.

As part of our capital management program, we may seek to raise additional capital or may seek to return capital to our shareholders through share repurchases, cash dividends or other methods (or a combination of such methods). We may also seek to retire or purchase our outstanding debt through cash purchases and/or exchanges for equity or debt, in open-market purchases, privately negotiated transactions or otherwise. Any such determination will be at the discretion of the Board and will be dependent upon our profits, financial requirements and other factors, including legal restrictions, rating agency requirements, prevailing market conditions and such other factors as our Board deems relevant. The amounts involved may be material.
Arch Capital, through its subsidiaries, provides financial support to certain of its insurance subsidiaries and affiliates, through certain reinsurance arrangements beneficial to the ratings of such subsidiaries. Historically, our insurance, reinsurance and mortgage insurance subsidiaries have entered into separate reinsurance arrangements with Arch Re Bermuda covering individual lines of business.

CATASTROPHIC AND SEVERE ECONOMIC EVENTS
We have large aggregate exposures to natural and man-made catastrophic events, pandemic events and severe economic events. Natural catastrophes can be caused by various events, including hurricanes, floods, windstorms, earthquakes, hailstorms, tornadoes, explosions, severe winter weather, fires, droughts and other natural disasters. Man-made catastrophic events may include acts of war, acts of terrorism and political instability. Catastrophes can also cause losses in non-property business such as mortgage insurance, workers’ compensation or general liability. In addition to the nature of property business, we believe that economic and geographic trends affecting insured property, including inflation, property value appreciation and geographic concentration, tend to generally increase the size of losses from catastrophic events over time.
Our models employ both proprietary and vendor-based systems and include cross-line correlations for property, marine, offshore energy, aviation, workers compensation and personal accident. We seek to limit the probable maximum pre-tax loss to a specific level for severe catastrophic events. Currently, we seek to limit our 1-in-250 year return period net probable maximum loss from a severe catastrophic event in any geographic zone to approximately 25% of tangible shareholders’ equity available to Arch (total shareholders’ equity available to Arch less goodwill and intangible assets). We reserve the right to change this threshold at any time.
Based on in-force exposure estimated as of April 1, 2026, our modeled peak zone catastrophe exposure was a windstorm affecting the Florida Tri-County regions, with a net probable maximum pre-tax loss of $1.9 billion, or 8.2% of tangible shareholders’ equity available to Arch, followed by windstorms affecting the Northeastern U.S. and the Gulf of Mexico regions with net probable maximum pre-tax losses of $1.6 billion and $1.5 billion, respectively. Our exposures to other perils, such as U.S. earthquake and international events, were less than the exposures arising from U.S. windstorms and hurricanes. As of April 1, 2026, our modeled peak zone earthquake exposure (San Francisco earthquake) represented approximately 48% of our peak zone catastrophe exposure, and our modeled peak zone international exposure (Germany windstorm) was substantially less than both our peak zone windstorm and earthquake exposures.
We also have significant exposure to losses due to mortgage defaults resulting from severe economic events in the future. For our U.S. and Australian mortgage insurance business, we have developed a proprietary risk model (“Realistic Disaster Scenario” or “RDS”) that simulates the maximum loss resulting from a severe economic downturn impacting the housing market. The RDS models the
collective impact of adverse conditions for key economic indicators, the most significant of which is a decline in home prices. The RDS model projects paths of future home prices, unemployment rates, income levels and interest rates and assumes correlation across states and geographic regions. The resulting future performance of our in-force portfolio is then estimated under the economic stress scenario, reflecting loan and borrower information.
Currently, we seek to limit our modeled RDS loss from a severe economic event to approximately 25% of tangible shareholders’ equity available to Arch. We reserve the right to change this threshold at any time. Based on in-force exposure estimated as of April 1, 2026, our modeled RDS loss was approximately $924 million, or 4.0% of tangible shareholders’ equity available to Arch.
Net probable maximum loss estimates are net of expected reinsurance recoveries, before income tax and before excess reinsurance reinstatement premiums. RDS loss estimates are net of expected reinsurance recoveries and before income tax. Catastrophe loss estimates are reflective of the zone indicated and not the entire portfolio. Since hurricanes and windstorms can affect more than one zone and make multiple landfalls, our catastrophe loss estimates include clash estimates from other zones. Our catastrophe loss estimates and RDS loss estimates do not represent our maximum exposures and it is highly likely that our actual incurred losses would vary materially from the modeled estimates. There can be no assurances that we will not suffer pre-tax losses greater than 25% of our tangible shareholders’ equity from one or more catastrophic events or severe economic events due to several factors. These factors include the inherent uncertainties in estimating the frequency and severity of such events and the margin of error in making such determinations resulting from potential inaccuracies and inadequacies in the data provided by clients and brokers, the modeling techniques and the application of such techniques or as a result of a decision to change the percentage of shareholders' equity exposed to a single catastrophic event or severe economic event. In addition, actual losses may increase if our reinsurers fail to meet their obligations to us or the reinsurance protections purchased by us are exhausted or are otherwise unavailable. See “Risk Factors—Risks Relating to Our Industry” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Catastrophic Events and Severe Economic Events” in our 2025 Form 10-K.

MARKET SENSITIVE INSTRUMENTS AND RISK MANAGEMENT
In accordance with the SEC’s Financial Reporting Release No. 48, we performed a sensitivity analysis to determine the effects that market risk exposures could have on the future earnings, fair values or cash flows of our financial instruments as of March 31, 2026. Market risk represents the risk of changes in the fair value of a financial instrument and is comprised of several components, including liquidity, basis and price risks.
An analysis of material changes in market risk exposures at March 31, 2026 that affect the quantitative and qualitative disclosures presented in our 2025 Form 10-K (see section captioned “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Market Sensitive Instruments and Risk Management”) were as follows: 
Investment Market Risk
Fixed Income Securities. We invest in interest rate sensitive securities, which are primarily debt securities. We consider the effect of interest rate movements on the fair value of our fixed maturities, short-term investments and certain of our other investments, equity securities and investments accounted for using the equity method which invest in fixed income securities (collectively, “Fixed Income Securities”) and the corresponding change in unrealized appreciation. As interest rates rise, the fair value of our Fixed Income Securities falls, and the converse is also true. Based on historical observations, there is a low probability that all interest rate yield curves would shift in the same direction at the same time. Furthermore, at times interest rate movements in certain credit sectors exhibit a much lower correlation to changes in U.S. Treasury yields. Accordingly, the actual effect of interest rate movements may differ materially from the amounts set forth in the following tables.
The following table summarizes the effect that an immediate, parallel shift in the interest rate yield curve would have had on our Fixed Income Securities:
(U.S. dollars in 
billions)		 Interest Rate Shift in Basis Points
-100 -50 — +50 +100
March 31, 2026
        
Total fair value $ 46.1  $ 45.5  $ 44.8  $ 44.2  $ 43.6 
Change from base 2.8  % 1.4  % (1.4) % (2.7) %
Change in unrealized value $ 1.3  $ 0.6  $ (0.6) $ (1.2)
December 31, 2025
Total fair value $ 45.8  $ 45.2  $ 44.6  $ 44.0  $ 43.3 
Change from base 2.8  % 1.4  % (1.4) % (2.8) %
Change in unrealized value $ 1.2  $ 0.6  $ (0.6) $ (1.2)
In addition, we consider the effect of credit spread movements on the market value of our Fixed Income Securities and the corresponding change in unrealized value. As credit spreads widen, the fair value of our Fixed Income Securities falls, and the converse is also true. In periods where the spreads on our Fixed Income Securities are much higher than their historical average due to short-term market dislocations, a parallel shift in credit spread levels would result in a much more pronounced change in unrealized value.
The following table summarizes the effect that an immediate, parallel shift in credit spreads in a static interest rate environment would have had on our Fixed Income Securities:
(U.S. dollars in 
billions)		 Credit Spread Shift in Percentage Points
-100 -50 — +50 +100
March 31, 2026
Total fair value $ 46.0  $ 45.4  $ 44.8  $ 44.2  $ 43.6 
Change from base 2.7  % 1.3  % (1.3) % (2.7) %
Change in unrealized value $ 1.2  $ 0.6  $ (0.6) $ (1.2)
December 31, 2025
Total fair value $ 45.8  $ 45.2  $ 44.6  $ 44.0  $ 43.3 
Change from base 2.8  % 1.4  % (1.4) % (2.8) %
Change in unrealized value $ 1.2  $ 0.6  $ (0.6) $ (1.2)
Another method that attempts to measure portfolio risk is Value-at-Risk (“VaR”). VaR measures the worst expected loss under normal market conditions over a specific time interval at a given confidence level. The 1-year 95th percentile parametric VaR reported herein estimates that 95% of the time, the portfolio loss in a one-year horizon would be less than or equal to the calculated number, stated as a percentage of the measured portfolio’s initial value. The VaR is a variance-covariance based estimate, based on linear sensitivities of a portfolio to a broad set of systematic market risk factors and idiosyncratic risk factors mapped to the portfolio exposures. The relationships between the risk
ARCH CAPITAL
 55
 2026 FIRST QUARTER FORM 10-Q
Table of Contents
factors are estimated using historical data, and the most recent data points are generally given more weight. As of March 31, 2026, our portfolio’s 95th percentile VaR was estimated to be 6.2%, compared to an estimated 6.5% at December 31, 2025. In periods where the volatility of the risk factors mapped to our portfolio’s exposures is higher due to market conditions, the resulting VaR is higher than in other periods.
Equity Securities. At March 31, 2026 and December 31, 2025, the fair value of our investments in equity securities and certain investments accounted for using the equity method with underlying equity strategies totaled $1.8 billion and $1.8 billion, respectively. These investments are exposed to price risk, which is the potential loss arising from decreases in fair value. An immediate hypothetical 10% decline in the value of each position would reduce the fair value of such investments by approximately $180 million and $178 million at March 31, 2026 and December 31, 2025, respectively, and would have decreased book value per share by approximately $0.51 and $0.50, respectively. An immediate hypothetical 10% increase in the value of each position would increase the fair value of such investments by approximately $180 million and $178 million at March 31, 2026 and December 31, 2025, respectively, and would have increased book value per share by approximately $0.51 and $0.50, respectively.
Investment-Related Derivatives. At March 31, 2026, the notional value of all derivative instruments (excluding foreign currency forward contracts which are included in the foreign currency exchange risk analysis below) was $10.0 billion, compared to $8.0 billion at December 31, 2025. If the underlying exposure of each investment-related derivative held at March 31, 2026 depreciated by 100 basis points, it would have resulted in a reduction in net income of approximately $100 million, and a decrease in book value per share of approximately $0.28 per share, compared to $80 million and $0.22 per share, respectively, on investment-related derivatives held at December 31, 2025. If the underlying exposure of each investment-related derivative held at March 31, 2026 appreciated by 100 basis points, it would have resulted in an increase in net income of approximately $100 million, and an increase in book value per share of approximately $0.28 per share, compared to $80 million and $0.22 per share, respectively, on investment-related derivatives held at December 31, 2025. See note 10, “Derivative Instruments,” to our consolidated financial statements for additional disclosures concerning derivatives.
For further discussion on investment activity, please refer to “Financial Condition—Investable Assets.”
Foreign Currency Exchange Risk
Foreign currency rate risk is the potential change in value, income and cash flow arising from adverse changes in foreign currency exchange rates. Through our subsidiaries and branches located in various foreign countries, we conduct our insurance and reinsurance operations in a variety of local currencies other than the U.S. Dollar. We generally hold investments in foreign currencies which are intended to mitigate our exposure to foreign currency fluctuations in our net insurance liabilities. We may also utilize foreign currency forward contracts and currency options as part of our investment strategy. See note 10, “Derivative Instruments,” to our consolidated financial statements for additional information.
The following table provides a summary of our net foreign currency exchange exposures, as well as foreign currency derivatives in place to manage these exposures:

Book value per share $ 0.37  $ 0.33 
(1)    Represents capital contributions held in the foreign currencies of our operating units.
(2)    Represents the net notional value of outstanding foreign currency forward contracts.
Although we generally attempt to match the currency of our projected liabilities with investments in the same currencies, from time to time we may elect to over or underweight one or more currencies, which could increase our exposure to foreign currency fluctuations and increase the volatility of our shareholders’ equity. Historical observations indicate a low probability that all foreign currency exchange rates would shift against the U.S. Dollar in the same direction and at the same time and, accordingly, the actual effect of foreign currency rate movements may differ materially from the amounts set forth above. For further discussion on foreign exchange activity, please refer to “Results of Operations.”

Effects of Inflation
General economic inflation has increased in recent quarters and may continue to remain at elevated levels for an extended period of time. The potential also exists, after a catastrophe loss or pandemic events, for the development of inflationary pressures in a local economy. This risk may be heightened from time to time by geopolitical tensions, global supply chain disruptions, tariffs, and other contributing factors. This may have a material effect on the adequacy of our reserves for losses and loss adjustment expenses, especially in longer-tailed lines of business, and on the market value of our investment portfolio through rising interest rates. The anticipated effects of inflation are considered in our pricing models, reserving processes and exposure management, across all lines of business and types of loss including natural catastrophe events. The actual effects of inflation on our results cannot be accurately known until claims are ultimately settled and will vary by the specific type of inflation affecting each line of business.

Re: Retirement

Dear John:

This letter sets forth our mutual agreement that your retirement from Arch Capital Group Ltd. (the “Company”) and its subsidiaries will be effective on June 30, 2026 (the “Retirement Date”).

The Employment Period under your Employment Agreement with the Company dated October 27, 2008, as amended, will terminate on the Retirement Date, and the termination will be a Justified Termination under clause (i)(b) of Section 5.03 of the Employment Agreement.

You will continue receive your base salary and benefits through the Retirement Date as provided by the Employment Agreement, and you will be eligible to receive a pro rata payment of your 2026 annual bonus award on the regular payment date under the Company’s Incentive Compensation Plan, subject to and in accordance with the terms and conditions of the Plan.

Following the Retirement Date, you will be eligible for group health plan continuation coverage under COBRA for 18 months (or until you become eligible for coverage from another employer). If you timely elect COBRA coverage, the Company will pay the monthly COBRA premium for the first 12 months of coverage, and the amount of the Company’s payment will be treated as taxable income to you. If you continue COBRA coverage after the first 12 months, you will be required to pay the full amount of the COBRA premium.

Please do not hesitate to contact Denis Allard should you have any questions regarding any of the above.

Sincerely,

THIS AGREEMENT, dated as of [insert date], between Arch Capital Group Ltd. (the “Company”), a Bermuda company, and [insert name] (the “Employee”).
WHEREAS, the Employee has been granted the following award under the Company’s Amended and Restated [insert year of Plan] Long Term Incentive and Share Award Plan (the “Plan”);
NOW, THEREFORE, in consideration of the premises and mutual covenants contained herein, the parties hereto agree as follows.
1.    Award of Shares.  Pursuant to the provisions of the Plan, the terms of which are incorporated herein by reference, the Employee is hereby awarded [insert award shares] Restricted Shares (the “Award”), subject to the terms and conditions herein set forth. Capitalized terms used herein and not defined shall have the meanings set forth in the Plan. In the event of any conflict between this Agreement and the Plan, the Plan shall control.

2.    Terms and Conditions.  It is understood and agreed that the Award of Restricted Shares evidenced hereby is subject to the following terms and conditions:

(a)    Vesting of Award. Subject to Section 2(b) below and the other terms and conditions of this Agreement, this Award shall become vested in three equal annual installments on the first, second and third anniversaries of the date hereof. Unless otherwise provided by the Company, all dividends and other amounts receivable in connection with any adjustments to the Shares under Section 4(c) of the Plan shall be subject to the vesting schedule in this Section 2(a).

(b)    Termination of Service; Forfeiture of Unvested Shares.

(i)    In the event the Employee ceases to be an employee of the Company prior to the date the Restricted Shares otherwise become vested due to his or her death or Permanent Disability (as defined in the Company’s Incentive Compensation Plan on the date hereof), the Restricted Shares shall become immediately vested in full upon such termination of employment.

(ii) In the event of termination of employment (other than by the Company for Cause, as such term is defined in the Company’s Incentive Compensation Plan on the date hereof, and other than as set forth in Section 2(b)(i) or (iii) hereof) after the attainment of Retirement Age (as defined in the Company’s Incentive Compensation Plan on the date hereof), the Restricted Shares shall continue to vest on the schedule set forth in Section 2(a) above so long as the Employee does not, without the written consent of the Company, engage in any activity in competition with any activity of the Company or any of its Subsidiaries other than (i) serving on the board of directors (or similar governing body) of another company or (ii) serving as a consultant for no more than 26 weeks per calendar year providing services that do not, in whole or in part, relate to the business or operations of an insurance or reinsurance company (“Competitive Activity”). In the event the Employee engages in a Competitive Activity, any unvested Restricted Shares shall be forfeited by the Employee and become the property of the Company.


(iii)    In the event of a Change in Control (as defined in the Plan) in connection with which the Award is assumed by the surviving entity or otherwise equitably converted or substituted in connection therewith in a manner approved by the Committee or the Board and after which the Employee ceases to be an employee of the Company due to termination (A) by the Company not for Cause or (B) by the Employee for Good Reason (as defined below), in either case, on or before the second anniversary of the occurrence of the Change in Control, the Restricted Shares, to the extent not already vested, shall become immediately vested in full upon such termination of employment. “Good Reason” shall have the meaning given to such term in any existing employment agreement between the Employee and the Company or Subsidiary as in effect on the date of grant of this Award or, in the absence of such an existing employment agreement in effect on the date of grant defining such term, it shall mean, without the Employee’s written consent, (a) the material diminution of any material duties or responsibilities of the Employee without the same being corrected within thirty (30) days after being given written notice thereof; or (b) a material reduction in the Employee’s base salary without the same being corrected within thirty (30) days after being given written notice thereof.

(iv)    If the Employee ceases to be an Employee of the Company for any other reason prior to the date the Restricted Shares become vested, the Award shall be forfeited by the Employee and become the property of the Company.

(v)    For purposes of this Agreement, service with any of the Company’s Subsidiaries (as defined in the Plan) shall be considered to be service with the Company.
(c)    Change in Control; Award Not Assumed. Notwithstanding any provision of this Agreement to the contrary, upon the occurrence of a Change in Control in connection with which the Award is not assumed by the surviving entity or otherwise equitably converted or substituted in connection therewith in a manner approved by the Committee or the Board, the Award shall vest in full on the effective date of the Change in Control. 
(d)     Certificates.  Each certificate issued in respect of Restricted Shares awarded hereunder shall be issued in book entry format with the Company’s transfer agent and shall bear a legend disclosing the restrictions on transferability imposed on such Restricted Shares by this Agreement (the “Restrictive Legend”). Upon the vesting of Restricted Shares pursuant to Section 2 hereof and the satisfaction of any withholding tax liability pursuant to Section 5 hereof, such vested Shares, not bearing the Restrictive Legend, shall be delivered to the Employee.

(e) Rights of a Stockholder. Prior to the time a Restricted Share is fully vested hereunder, the Employee shall have no right to transfer, pledge, hypothecate or otherwise encumber such Restricted Share. During such period, the Employee shall have all other rights of a stockholder, including, but not limited to, the right to vote and to receive dividends (subject to Section 2(a) hereof) at the time paid on such Restricted Shares.
2


(f)    No Right to Continued Employment. This Award shall not confer upon the Employee any right with respect to continuance of employment by the Company nor shall this Award interfere with the right of the Company to terminate the Employee’s employment at any time.
3.    Transfer of Shares. The Shares delivered hereunder, or any interest therein, may be sold, assigned, pledged, hypothecated, encumbered, or transferred or disposed of in any other manner, in whole or in part, only in compliance with the terms, conditions and restrictions as set forth in the governing instruments of the Company, applicable United States federal and state securities laws or any other applicable laws or regulations and the terms and conditions hereof.

4.    Expenses of Issuance of Shares. The issuance of stock certificates hereunder shall be without charge to the Employee. The Company shall pay any issuance, stamp or documentary taxes (other than transfer taxes) or charges imposed by any governmental body, agency or official (other than income taxes) or by reason of the issuance of Shares.

5.    Withholding. No later than the date of vesting of (or the date of an election by the Employee under Section 83(b) of the Code with respect to) the Award granted hereunder, the Employee shall pay to the Company or make arrangements satisfactory to the Committee regarding payment of any federal, state or local taxes of any kind required by law to be withheld at such time with respect to such Award and the Company shall, to the extent permitted or required by law, have the right to deduct from any payment of any kind otherwise due to the Employee, federal, state and local taxes of any kind required by law to be withheld at such time.

6.    References.  References herein to rights and obligations of the Employee shall apply, where appropriate, to the Employee’s legal representative or estate without regard to whether specific reference to such legal representative or estate is contained in a particular provision of this Agreement.

7.    Notices.  Any notice required or permitted to be given under this Agreement shall be in writing and shall be deemed to have been given when delivered personally or by courier, or sent by certified or registered mail, postage prepaid, return receipt requested, duly addressed to the party concerned at the address indicated below or to such changed address as such party may subsequently by similar process give notice of:

Exhibit 10.3
For Awards for Named Executive Officers and
Certain Executive Officers of ACGL and subsidiaries


ARCH CAPITAL GROUP LTD.
Non-Qualified Stock Option Agreement
FOR GOOD AND VALUABLE CONSIDERATION, receipt of which is hereby acknowledged, Arch Capital Group Ltd. (the “Company”), a Bermuda company, hereby grants to
[insert name], an employee of the Company on the date hereof (the “Option Holder”), the option to purchase common shares, $0.0011 par value per share, of the Company (“Shares”), upon the following terms:
WHEREAS, the Option Holder has been granted the following award under the Company’s Amended and Restated [insert year of Plan] Long Term Incentive and Share Award Plan (the “Plan”);
(a)Grant. The Option Holder is hereby granted an option (the “Option”) to purchase [insert number of option shares] Shares (the “Option Shares”) pursuant to the Plan, the terms of which are incorporated herein by reference. The Option is granted as of [insert date] (the “Date of Grant”) and such grant is subject to the terms and conditions herein and the terms and conditions of the applicable provisions of the Plan. This Option shall not be treated as an incentive stock option as defined in Section 422 of the Internal Revenue Code of 1986, as amended. In the event of any conflict between this Agreement and the Plan, the Plan shall control.
(b)Status of Option Shares. Upon issue, the Option Shares shall rank equally in all respects with the other Shares.
(c)Option Price. The purchase price for the Option Shares shall be, except as herein provided, $[insert price] per Option Share, hereinafter sometimes referred to as the “Option Price,” payable immediately in full upon the exercise of the Option.
(d)Term of Option. The Option may be exercised only during the period (the “Option Period”) set forth in paragraph (f) below and shall remain exercisable until the tenth anniversary of the Date of Grant. Thereafter, the Option Holder shall cease to have any rights in respect thereof. The right to exercise the Option shall be subject to sooner termination as provided in paragraph (j) below.
(e)No Rights of Shareholder. The Option Holder shall not, by virtue hereof, be entitled to any rights of a shareholder in the Company, either at law or in equity.
(f)Exercisability. Except as otherwise set forth in paragraph (j) below, the Option shall become exercisable in three equal annual installments on the first, second and third anniversaries of the Date of Grant, in each case subject to paragraph (j) below. Subject to paragraph (j) below, the Option may be exercised at any time or from time to time during the Option Period in regard to all or any portion of the Option which is then exercisable, as may be adjusted pursuant to paragraph (g) below.
(g)Anti-dilution Adjustment. For the avoidance of doubt, the terms of Section 4(c) of the Plan, relating to anti-dilution adjustments, will apply to the Option.
1
image_0a.jpg

(h)Nontransferability. The Option, or any interest therein, may not be assigned or otherwise transferred, disposed of or encumbered by the Option Holder, other than by will or by the laws of descent and distribution. During the lifetime of the Option Holder, the Option shall be exercisable only by the Option Holder or by his or her guardian or legal representative. Notwithstanding the foregoing, the Option may be transferred by the Option Holder to members of his or her “immediate family” or to a trust or other entity established for the exclusive benefit of solely one or more members of the Option Holder’s “immediate family.” Any Option held by the transferee will continue to be subject to the same terms and conditions that were applicable to the Option immediately prior to the transfer, except that the Option will be transferable by the transferee only by will or the laws of descent and distribution. For purposes hereof, “immediate family” means the Option Holder’s children, stepchildren, grandchildren, parents, stepparents, grandparents, spouse, siblings (including half brothers and sisters), in laws, and relationships arising because of legal adoption.
(i)Exercise of Option. In order to exercise the Option, the Option Holder shall, in the manner directed by the Company, specify the whole number of Option Shares in respect of which the Option is being exercised, accompanied by payment, in a manner acceptable to the Company (which shall include a broker assisted exercise arrangement), of the Option Price for the Option Shares for which the Option is being exercised. Payment to the Company in cash or Shares already owned by the Option Holder (provided that the Option Holder has owned such Shares for a minimum period of six months or has purchased such Shares on the open market) and having a total Fair Market Value equal to the exercise price, or in a combination of cash and such Shares, shall be deemed acceptable for purposes hereof. In addition, in lieu of making payment of the exercise price of the Option and receiving the number of Shares for which the Option is being exercised as described above, the Option Holder may instead elect to exercise the Option by making no cash exercise price payment but having the Company issue to the Option Holder the number of Shares (rounded down to the nearest whole number) equal to the net result obtained by (A) subtracting the exercise price per Share from the Fair Market Value per Share on the date of exercise, (B) multiplying the difference by the number of Shares for which the Option is being exercised, and (C) dividing the product by the Fair Market Value per Share on the date of exercise. For the avoidance of doubt, if the calculation in the immediately preceding sentence results in a negative number, no Shares will be issued upon exercise. Option Shares will be issued accordingly by the Company, and a share certificate dispatched or electronic delivery of such Option Shares to the Option Holder within 30 days.
The Company shall not be required to issue fractional Shares upon the exercise of the Option. If any fractional interest in a Share would be deliverable upon the exercise of the Option in whole or in part but for the provisions of this paragraph, the Company, in lieu of delivering any such fractional share therefor, shall pay a cash adjustment therefor in an amount equal to their Fair Market Value multiplied by the fraction of the fractional share which would otherwise have been issued hereunder. Anything to the contrary herein notwithstanding, the Company shall not be obligated to issue any Option Shares hereunder if the issuance of such Option Shares would violate the provision of any applicable law, in which event the Company shall, as soon as practicable, take whatever action it reasonably can so that such Option Shares may be issued without resulting in such violations of law.
(j)Termination of Service.
1.In the event the Option Holder ceases to be an employee of the Company due to the Option Holder’s death or Permanent Disability (as defined in the Company’s Incentive Compensation Plan on the date hereof), the Option, to the extent not already exercisable in full, shall become immediately exercisable in full and shall continue to be exercisable by the Option Holder (or the Option Holder’s Beneficiary or estate in the event of the Option Holder’s death) for a period of three years following such termination of employment (but not beyond the Option Period).
2
image_0a.jpg

2.In the event of termination of employment (other than by the Company for Cause, as such term is defined in the Company’s Incentive Compensation Plan on the date hereof and other than as set forth in paragraphs (j)(1) or (j)(3) hereof) after the attainment of Retirement Age (as defined in the Company’s Incentive Compensation Plan on the date hereof), the Option shall continue to become exercisable on the schedule set forth in paragraph (f) above so long as the Option Holder does not, without the written consent of the Company, engage in any activity in competition with any activity of the Company or any of its Subsidiaries other than (i) serving on the board of directors (or similar governing body) of another company or (ii) serving as a consultant for no more than 26 weeks per calendar year providing services that do not, in whole or in part, relate to the business or operations of an insurance or reinsurance company (“Competitive Activity”) and shall continue to be exercisable by the Option Holder (or the Option Holder’s Beneficiary or estate in the event of the Option Holder’s death) for the remainder of the Option Period. In the event the Option Holder engages in a Competitive Activity, (A) the Option, to the extent then exercisable, may be exercised for 30 days following the date on which the Option Holder engages in such Competitive Activity (but not beyond the Option Period) and (B) the Option, to the extent then not exercisable, shall be immediately forfeited.
3.In the event of a Change in Control (as defined in the Plan) in connection with which the Option is assumed by the surviving entity or otherwise equitably converted or substituted in connection therewith in a manner approved by the Committee or the Board and after which the Option Holder ceases to be an employee of the Company due to termination (A) by the Company not for Cause or (B) by the Option Holder for Good Reason (as defined below), in either case, on or before the second anniversary of the occurrence of the Change in Control, the Option, to the extent not already exercisable in full, shall become immediately exercisable in full and shall continue to be exercisable by the Option Holder for a period of 90 days following such termination of employment (but not beyond the Option Period). “Good Reason” shall have the meaning given to such term in any existing employment agreement between the Option Holder and the Company or Subsidiary as in effect on the date of grant of this Option or, in the absence of such an existing employment agreement in effect on the date of grant defining such term, it shall mean, without the Option Holder’s written consent, (a) the material diminution of any material duties or responsibilities of the Option Holder without the same being corrected within thirty (30) days after being given written notice thereof; or (b) a material reduction in the Option Holder’s base salary without the same being corrected within thirty (30) days after being given written notice thereof.
4.In the event that the Option Holder ceases to be an employee of the Company for any other reason, except due to a termination of the Option Holder’s employment by the Company for Cause, (A) the Option, to the extent then exercisable, may be exercised for 90 days following termination of employment (but not beyond the Option Period) and (B) the Option, to the extent then not exercisable, shall be immediately forfeited.
5.In the event of a termination of the Option Holder’s employment for Cause, the Option shall immediately cease to be exercisable and shall be immediately forfeited.
6.For purposes of this Option, service with any of the Company’s Subsidiaries (as defined in the Plan) shall be considered to be service with the Company.
(k)Change in Control; Option Not Assumed. Notwithstanding any provision of this Agreement to the contrary, upon the occurrence of a Change in Control in connection with which the Option is not assumed by the surviving entity or otherwise equitably converted or substituted in connection therewith in a manner approved by the Committee or the Board, the Option shall vest in full on the effective date of the Change in Control.
3
image_0a.jpg

(l)Obligations as to Capital. The Company agrees that it will at all times maintain authorized and unissued share capital sufficient to fulfill all of its obligations under the Option.
(m)Transfer of Shares. The Option, the Option Shares, or any interest in either, may be sold, assigned, pledged, hypothecated, encumbered, or transferred or disposed of in any other manner, in whole or in part, only in compliance with the terms, conditions and restrictions as set forth in the governing instruments of the Company, applicable United States federal and state securities laws and the terms and conditions hereof.
(n)Expenses of Issuance of Option Shares. The issuance of stock certificates or the electronic delivery of Option Shares upon the exercise of the Option in whole or in part, shall be without charge to the Option Holder. The Company shall pay any issuance, stamp or documentary taxes (other than transfer taxes) or charges imposed by any governmental body, agency or official (other than income taxes) by reason of the exercise of the Option in whole or in part or the resulting issuance of the Option Shares.
(o)Withholding. No later than the date of exercise of the Option granted hereunder, the Option Holder shall pay to the Company or make arrangements satisfactory to the Committee regarding payment of any federal, state or local taxes of any kind required by law to be withheld upon the exercise of such Option and the Company shall, to the extent permitted or required by law, have the right to deduct from any payment of any kind otherwise due to the Option Holder, federal, state and local taxes of any kind required by law to be withheld upon the exercise of such Option.
(p)References. References herein to rights and obligations of the Option Holder shall apply, where appropriate, to the Option Holder’s legal representative or estate without regard to whether specific reference to such legal representative or estate is contained in a particular provision of this Option.
(q)Notices.

Exhibit A

The Restricted Shares will vest contingent upon (i) the level of achievement in Tangible Book Value Per Share (“TBVPS”) at the end of the Performance Period, as modified by Relative Total Stock Return (“TSR”) Performance, all as set forth below, and (ii) except as otherwise set forth in the Agreement, continued employment by the Employee through the Vesting Date set forth in the Agreement.

TBVPS at the beginning of the Performance Period is $[insert TBVPS].

Level of Performance Compounded Growth in TBVPS (per annum) TBVPS at the end of the Performance Period Initial Shares Earned as % of Target
Below Threshold <__% n/a 0%
Threshold __% $__ 50%
Target __% $__ 100%
Maximum __% $__ 200%

Results that are between the levels set forth above will be calculated by linear interpolation.
Relative TSR Modifier

The initial number of Restricted Shares earned based on TBVPS at the end of the Performance Period as determined above will be adjusted by the Percentage Modification Factor set forth below based on the Company’s Relative TSR Performance percentile ranking over the Performance Period; provided, however, that if the Company’s TSR for the Performance Period is less than zero, then the number of earned Restricted Shares will not be adjusted upward.

Relative TSR Performance                Percentage Modification Factor

Greater than or equal to 80th                    25%
35th to 65th                            0%
Less than or equal to 20th                     -25%

The Percentage Modification Factor for Percentage Rankings that are between the Percentile Ranking values set forth above will be calculated by linear interpolation.

Subject to the annual growth in TBVPS being greater than the Threshold, the Modified Threshold Restricted Shares will be equal to 37.5% of the Target Restricted Shares and the Modified Maximum Restricted Shares will be equal to 250.0% of the Target Restricted Shares. No Restricted Shares will be earned if the annualized growth rate in TBVPS over the Performance Period is below the Threshold set forth above.

Fractional Shares Rounded

In the event the overall calculation results in fractional shares, the amount of such resulting shares will be rounded to the nearest whole share (or down if exactly halfway between).

Definitions:

“TBVPS” means, except as otherwise provided below, the tangible book value per common share outstanding of the Company as reported by the Company.  For this purpose, TBVPS at the beginning and end of the Performance Period shall each be computed by excluding goodwill and intangible assets (excluding amounts attributable to non-controlling interests) and accumulated other comprehensive income (loss) (“AOCI”), net of deferred income tax related to AOCI, as presented on the Company’s balance sheet.  TBVPS calculations may be modified by the Compensation and Human Capital Committee (“CHCC”) to reflect transactions not in the ordinary course of business which may affect tangible book value per share (including, but not limited to, share issuances or conversions, share repurchases, extraordinary distributions, and capital adjustments or other transactions affecting tangible book value per share) or in response to other unusual or non-recurring events or changes in applicable laws, regulations, or accounting principles (including, but not limited to, changes affecting the determination of the deferred income tax assets or liabilities reflected or disclosed in the Company’s financial statements or otherwise in connection with or relating to the imposition of a global minimum tax). The determination of TBVPS by the CHCC shall be final and binding on the Company and the Employee.

“Performance Period” means the three-year period beginning on [insert first day of performance period] and ending on [insert last day of performance period].

“TSR” means the total return to a shareholder over the prescribed period, including dividends (assuming reinvestment in the shares at the month end closing price for the month of the ex-dividend date for the dividend) and share price appreciation (or decline).

“Relative TSR Performance” will be calculated as follows for each applicable Performance Period:

(i)TSR for the Company and each company (“Peer Company”) in the “Peer Group” (as defined below) will be calculated as a straight ratio of ending value to beginning value over the applicable Performance Period.  In order to reduce volatility, each periodic TSR measurement will start and end with the average closing stock price for the first and last months in the applicable Performance Period, respectively.
(ii)The Company’s percentile ranking will be determined as follows:
Percentile Ranking = [(n-r)/(n-1)] x 100

Where n equals the number of Peer Companies within the Peer Group, including the Company, and r equals the Company’s ranking within the list of Peer Group companies, including the Company.

For example, if the Company ranks seventh and there are sixteen companies in the peer group (including the Company), the Company’s Percentile Ranking will be 60, which is equal to [(16-7)/(16-1)] x 100. 

The Peer Group shall be comprised of the following Peer Companies for which TSR computations can be made from publicly available information for the entire Performance Period, subject to the exceptions noted below. Any member of the Peer Group that files for bankruptcy during the Performance Period will be treated as having a negative one hundred percent (-100%) TSR for the Performance Period.

(i)the Peer Company consummates a corporate transaction of any type such that it is not the surviving entity (including a corporate transaction under which it sells all or substantially all of its assets),
(ii)the Peer Company is acquired by the Company or any of its Subsidiaries or
The Peer Company is delisted from the securities exchange on which it was listed at the beginning of the Performance Period (other than due to bankruptcy of the Peer Company) and following such delisting the Peer Company is not immediately relisted on a U.S. national securities exchange and remains listed on such exchange for the remainder of the Performance Period.
