Arch Capital Earnings: Why Did Operating EPS Beat While Book Value Slipped?

Arch Capital Group (NASDAQ:ACGL) reported third-quarter results on Tuesday, October 27, with after-tax operating income of $910 million, or $2.67 per diluted share, against $1,042 million, or $2.77. As screened, the estimate was $2.30. Net income available to common was $1,025 million, or $3.00 per share, against $1,340 million, or $3.56.

Book value per common share was $67.90, down 0.2% from June 30. A total investment return of negative 0.42%, which the release linked mainly to rising interest rates, and $99 million of net realized losses weighed on the balance sheet. Annualized operating return on equity was 16.0%, against 18.5%.

Arch writes insurance, reinsurance and mortgage insurance. Its chief executive described a strong quarter and a transitioning market with increasingly uneven conditions.

Underwriting: Where Did the 82.5% Combined Ratio Come From?

The consolidated combined ratio was 82.5%, against 79.8%, and 81.2% excluding catastrophes and prior-year development, against 80.5%. Underwriting income was $702 million against $871 million, a decline of 19.4%.

Insurance posted a 94.4% combined ratio, or 89.2% excluding catastrophes and development, against 91.3% a year earlier. Reinsurance recorded 78.3%, against 76.1%, with 7.0 points of favorable development. Mortgage recorded 25.5%, against 13.5%, and 41.6% excluding prior-year development, as delinquencies were modestly higher.

Current-year catastrophe losses were $234 million pre-tax, including losses tied to the Iran conflict in the insurance segment. Favorable prior-year development totaled $179 million. Catastrophe losses added 5.7 points to the insurance loss ratio against 2.2 points, and 6.9 points in reinsurance against 1.5 points. Mortgage favorable development was 16.1 points, which the release tied mainly to better-than-expected cure rates.

Premiums and Investments: Is Growth Cooling While Income Rises?

Net premiums written fell 3.0% to $3,845 million. Insurance rose 2.7% to $2,006 million, reinsurance fell 9.3% to $1,576 million and mortgage fell 4.0% to $263 million. Gross premiums written were $5,391 million, down 0.4%. Net premiums earned declined 6.3% to $4,014 million, with insurance earned premiums down 1.6% to $1,937 million, reinsurance down 10.3% to $1,807 million and mortgage down 10.3% to $270 million.

Net investment income rose to $451 million from $408 million, or $1.32 per share against $1.08, on a pre-tax yield of 4.09%. Equity-method income was $224 million against $134 million. Interest expense rose to $62 million from $37 million, mainly reflecting the June 2026 capital raise.

Capital Returns: What Does the $1.4 Billion Buyback Signal Next?

Arch repurchased $1.4 billion of shares in the quarter, lowering diluted shares to 341.4 million from 376.1 million a year earlier. Common equity was $22,162 million and total capital about $27.3 billion. Annualized net income return on equity was 18.1% against 23.8%. The effective tax rate was 15.1%, and corporate expenses were $5 million, helped by Bermuda refundable tax credits. The release gave no formal guidance, and the 2026 capital raise has been followed by heavy repurchases, so investors will watch pricing trends, mortgage cures and catastrophe activity in coming quarters.
