Premium rates remained competitive in E&S property and professional lines.

Current wording

Our insurance segment reported a $2 million underwriting loss, primarily attributable to the California wildfires. Growth in net premiums written reflected a significant contribution from the U.S MidCorp and Entertainment Insurance businesses acquired from Allianz on August 1, 2024 (“MCE Acquisition”) of $373 million, or 24.2 points of growth, compared to the 2024 first quarter. The integration of the MCE Acquisition is progressing well, and we remain excited about the increased capabilities this team brings to our insurance platform. In the current insurance market, there is increased volatility, and it is possible to achieve double-digit growth in some lines while experiencing similar declines in others. In the 2025 first quarter, we generated meaningful growth in casualty led lines including construction, national accounts casualty and international casualty. At the same time, we experienced premium reductions in other lines of business like E&S property and professional lines (including cyber) due to rate decreases and our desire to maintain margins. We have seen competition increasing in specialty lines in the London market, and believe we can benefit from consolidation around market leaders. Looking ahead, we believe we are well positioned across the insurance segment and expect continued growth in casualty led lines as well as the U.S. middle market, where opportunities remain for both rate and premium growth.

Previous wording

Our mortgage segment continued to deliver a steady level of earnings for our shareholders, generating $269 million of underwriting income in the 2024 third quarter. While new originations remain 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 82.9% and the delinquency rate remained low.

The persistency of our in force U.S. primary mortgage insurance portfolio remained a healthy 81.9% and our delinquency rate remained low. While recessionary trends resulting from tariffs or other economic policies could create headwinds, we still expect the mortgage segment to continue generating attractive underwriting income given the high credit quality and embedded equity of our in-force portfolio.

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 $57.00 at September 30, 2024, compared to $52.75 at June 30, 2024, and $38.62 at September 30, 2023. The 8.1% increase in book value per share for the 2024 third quarter reflected strong investment results.

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 includes realized and unrealized changes in the fair value of equity securities and assets accounted for using the fair value option, realized and unrealized gains 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 investment funds accounted for using the equity method, net foreign exchange gains or losses,

Previous wording

Total return for the 2024 periods primarily reflected the effects of sustained higher interest rates available in the market, along with growth in invested assets due in part to strong operating cash flows. We continue to maintain a relatively short duration on our portfolio of 2.68 years at September 30, 2024, with average credit ratings of “AA-” from Standard & Poor’s Rating Services (“S&P”) and “Aa3” from Moody’s Investors Service (“Moody’s).

the duration and rating of its constituent securities change, generally we do not adjust the composition of the benchmark return index 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. The index is intended solely to provide a relatively stable basket of investable indices, unlike many master indices that change based on the size of their constituent indices. At September 30, 2024, the benchmark return index had an estimated duration of 2.50 years and an average credit quality of “A1” by Moody’s.

Current wording

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, 2025, the fixed income portion of the benchmark had an average credit quality of “A1” by Moody’s and an estimated fixed income duration of 3.33 years.

We believe that net realized gains or losses, equity in net income or loss of investment funds accounted for using the equity method, net foreign exchange gains or losses, transaction costs and other 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 investment funds 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. 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 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 that we account for our other investments and the timing of the recognition of equity in net income or loss of investment funds accounted for using the equity method may differ from gains or losses in the future upon sale or maturity of such investments.
