The following is a discussion and analysis of our financial condition and results of operations. This should be read in conjunction with our consolidated financial statements included in Item 1 of this report and also our Management’s Discussion and Analysis of Financial Condition and Results of Operations contained in our Annual Report on Form 10-K for the year ended December 31, 2024 (“2024 Form 10-K”). In addition, readers should review “Risk Factors” set forth in Item 1A of Part I of our 2024 Form 10-K and “ITEM 1A—Risk Factors” of this Form 10-Q. All amounts are in millions, except per share amounts, unless otherwise noted.

Arch Capital Group Ltd. (“Arch Capital” and, together with its subsidiaries, “Arch”, “the Company”, “we”, “our” or “us”) is a publicly listed Bermuda exempted company with approximately $25.8 billion in capital at June 30, 2025 and, through operations in Bermuda, the United States, Europe, Canada and Australia, writes insurance, reinsurance and mortgage insurance on a worldwide basis.

CURRENT OUTLOOK

We reported solid results for the 2025 second quarter, with an annualized net income return on average common equity and operating return on average common equity of 22.9% and 18.2%, respectively. See “Comment on Non-GAAP Financial Measures.” Book value per share grew 7.3% in the 2025 the second quarter, reflecting our disciplined underwriting and capital management. 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. This approach, combined with a diversified global platform and strong distribution relationships, allows us to adapt dynamically to shifting market conditions. We focus on practicing disciplined underwriting that builds a meaningful margin of safety into pricing, take a long-term view of risk and a prudent approach to reserving.

Our core objective to deliver long-term value for our shareholders remains unchanged. We will continue to execute on the key pillars of our strategy which are: to build a diversified mix of businesses; to actively manage the underwriting cycle; to remain prudent stewards of the capital entrusted to us by our shareholders; and to be dynamic managers of a data-driven enterprise with a culture that attracts best-in-class talent.

Overall, property and casualty market conditions remain largely consistent with the 2025 first quarter. Some sectors are seeing increased price competition while others continue to experience rate improvements. We believe the property and casualty market still presents meaningful opportunities for disciplined underwriters to generate attractive risk-adjusted returns on capital.

Our insurance segment reported $129 million of underwriting income for the 2025 second quarter, with net premium written surpassing $2 billion, which is an increase of 30.7% from the 2024 second quarter. Growth in net premiums written primarily resulted from the U.S MidCorp and Entertainment Insurance businesses acquired from Allianz on August 1, 2024 (“MCE Acquisition”). The integration of the MCE Acquisition is progressing well, and we remain excited about the increased capabilities this team brings to our insurance platform. Organic growth outside of the MCE Acquisition was modest, and growing our presence in middle market remains central to our strategy in North America. We saw selective growth in casualty lines, particularly in alternative market, E&S casualty and large account casualty, where pricing continued to outpace loss trends. However, competitive pressure persists in E&S property, excess D&O and cyber. While pricing in excess D&O and cyber appears to be stabilizing, we are maintaining a cautious stance, and prioritizing margin over volume in

these lines. Internationally, our Lloyd’s and London market businesses are experiencing increased, but rational, competition. Our long-term investment in establishing a leadership position at Lloyd’s continues to yield strong results reflected in favorable signings and our ability to attract top-tier underwriting talent.

Our reinsurance segment contributed $451 million of underwriting income in the 2025 second quarter, with over $2 billion of net premiums written. We are growing selectively and focusing on areas where margins are attractive. We anticipate continued selective growth in quota share arrangements in casualty lines and are willing to lean in—partnering with underwriting teams with strong expertise in complex liability risks. We also expanded our property catastrophe writings, primarily in Florida, where we saw attractive risk-adjusted returns and increased demand from clients for additional limits. Specialty lines remained a strategic focus, and our teams found several new opportunities this quarter. That said, our property other than property catastrophe excess of loss portfolio contracted, as cedants retained more risk and margins on certain portions of the portfolio fell below our target. We were generally pleased with the state of the mid-year catastrophe excess of loss renewals. While pricing was slightly down, margins remain attractive with primary insurers maintaining high retentions.

Our mortgage segment continued to deliver a steady level of earnings for our shareholders, generating $238 million of underwriting income in the 2025 second quarter, due to the strength of our in-force portfolio. While new originations were tempered by relatively high mortgage interest rates, underlying fundamentals remained strong and our U.S. market share was stable as industry pricing discipline held. The persistency of our in force U.S. primary mortgage insurance portfolio remained a healthy 81.9% and our delinquency rate remained low. While economic uncertainty could create headwinds, we still expect the mortgage segment to continue generating attractive underwriting income given the high credit q

Evaluation of Disclosure Controls and Procedures

In connection with the filing of this Form 10-Q, our management, with the participation of our Chief Executive Officer and Chief Financial Officer, conducted an evaluation of the Company’s disclosure controls and procedures, as of the end of the period covered by this report, for the purposes set forth in the applicable rules under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Based on that evaluation and subject to the below, our Chief Executive Officer and Chief Financial Officer concluded that the Company’s disclosure controls and procedures were effective as of the end of the period covered by this report. Disclosure controls and procedures are the controls and other procedures designed to ensure that information required to be disclosed in the reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to management, including the Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

On August 1, 2024, we completed the MCE Acquisition, and we are currently integrating the MCE Acquisition into our internal control system. Consistent with guidance issued by the SEC, we are excluding the internal control over financial reporting of MCE Acquisition from our evaluation of the effectiveness of our disclosure controls and procedures described above as of June 30, 2025. The MCE Acquisition represents 1.4% of total assets, and 7.8% of total revenues as of June 30, 2025.

Changes in Internal Control Over Financial Reporting

Other than the item noted above, there have been no changes in internal control over financial reporting that occurred during the quarter ended June 30, 2025 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
