ARCH CAPITAL GROUP LTD. ACGL

Arch repurchased $732 million of shares in Q3 FY25 and an additional $250 million in October, totaling 15.1 million shares or 4% of outstanding shares year-to-date. Management indicated a preference for buybacks over special dividends in the current environment, citing strong earnings and an attractive stock price. The company maintains a strong balance sheet and low leverage, providing flexibility for continued capital return and investment in the business.

The insurance segment delivered $129 million in underwriting income, an 8% year-over-year increase, on nearly $2 billion of net premium written. The combined ratio was 93.4%, with a current accident year ex-cat combined ratio of 91.3%. Growth was seen in North America other liability (17%) and property/short-tail (15%). The MidCorp and Entertainment acquisition is strategically driving middle market growth, with portfolio rollover completed and remediation/system separation on target, despite some non-renewals.

Reinsurance achieved a record $482 million in underwriting income with a 76.1% combined ratio, a significant improvement from the prior year. Net premium written was $1.7 billion, down 11% year-over-year, primarily due to the non-renewal of two large 3Q24 specialty transactions and increased retention by cedents. Property cat lines represent only 14% of trailing 12-month net premium written, highlighting the segment's diversification.

The mortgage segment continued its strong performance, generating $260 million in underwriting income for the quarter and is on pace to deliver approximately $1 billion for the full year. The segment's high-quality in-force portfolio is outperforming expectations, supported by a healthy broader mortgage insurance market. The delinquency rate for USMI increased seasonally to 2.04%, but the business remains a steady and diversifying contributor to Arch's earnings.

Investable assets grew to $46.7 billion, contributing a record $408 million in net investment income for the quarter. The portfolio is conservatively positioned to generate reliable and sustainable earnings and cash flows. Strong positive cash flow from operations, totaling $2.2 billion in the quarter, is expected to further support the growth of the investment portfolio.

Management acknowledged increasing competition and moderating rates, particularly in property cat, where rates decreased 5-10% in 2025. Arch emphasizes its cycle management approach, utilizing risk-based pricing tools and underwriting discipline to pursue profitable growth. Opportunities are seen in casualty lines, where rates are believed to be increasing faster than loss costs, and in the middle market.

While generally bullish on the MGA model, management expressed caution regarding historical outcomes due to potential misaligned incentives and information delays. The company is actively remediating the MGA portfolio acquired with MCE, with approximately $200 million of premium identified for non-renewal. The impact of these non-renewals is expected to be more visible in 2026 due to notice periods.

Arch's AA- S&P rating is considered an advantage, especially in Europe and for MI CRT/SRT transactions, despite the associated requirement to hold AAA capital. Management stated that their capital position was already strong, and the AAA capital level is not new. They continuously evaluate the trade-off between maintaining the rating and deploying capital, noting their current strong position and flexibility.
