Arch Capital Group Ltd. Q3 FY2026 earnings call

• Capital Management & Returns: ARCH returned approximately $1.4 billion to shareholders through buybacks in Q3, taking advantage of an attractive stock price. Through nine months of 2026, the company repurchased ~109% of its net income. Tangible book value per share increased ~15% year-over-year.
• Underwriting Discipline: Management emphasizes 'cycle management,' prioritizing risk-adjusted returns over premium growth. They are reducing exposure in competitive property/short-tail lines while maintaining or growing in attractive casualty segments.
• Iran Conflict Impact: The ongoing Iran conflict contributed to significant premium growth in Marine War Breach coverage for the Insurance segment, which improved the ex-cat loss ratio. Catastrophe losses of $234 million included losses associated with this conflict.
• Operational Efficiency: The Insurance expense ratio benefited from Bermuda Qualified Reinsurance Transaction Credits (QRTCs), which are viewed as sustainable. Integration costs for middle-market business duplication are largely behind them.
• Market Position: ARCH leverages its brand and data analytics to be highly selective. In reinsurance, they utilize third-party capital to manage net exposure and optimize returns on their own capital without chasing market index growth.

Insurance: Generated $108 million of underwriting income with a combined ratio of 94.4% (ex-cat accident year combined ratio of 89.2%). Gross premiums written increased 7.8% and net premiums written increased 2.7% year-over-year, driven by new captive programs and Marine War Breach coverage related to the Iran conflict.

Reinsurance: Delivered $393 million of underwriting income with a combined ratio of 78.3%, aided by light catastrophe activity. Net premiums written declined approximately 9.3% year-over-year due to reduced participation in property and short-tail lines where returns were unattractive, though casualty saw growth opportunities.

Mortgage Insurance (USMI & International): Produced $201 million of underwriting income. New origination volume remains constrained due to mortgage interest rates above 7%. The in-force portfolio maintains strong credit quality with a low delinquency rate of 2.2% and high persistency around 80%.

Investments: Contributed $451 million of pre-tax net investment income. Equity method investments performed strongly, contributing $224 million to pre-tax net income.

• Insurance Growth: Underlying insurance premium growth is expected to remain in the low single digits for the full year 2026. However, management anticipates better growth opportunities in 2027 compared to 2026, particularly in U.S. middle-market casualty and specialty lines.
• Reinsurance Trends: Continued pressure on short-tail and property catastrophe renewals is expected due to abundant capacity and moderating rates. Management does not provide specific numerical guidance but notes that reinsurance margins may face headwinds as pricing decelerates.
• Expense Ratio: The expense ratio is expected to improve slightly from current levels due to the sustained benefit of Bermuda tax credits and normalization of integration expenses, assuming premium trends remain stable.
• Catastrophe Activity: No specific guidance provided, but management noted the quarter had light catastrophe activity aside from the Iran-related events, which helped keep the overall ex-cap accident year combined ratio at 81.2%.

• Regulatory Changes in Mortgage Insurance: Potential regulatory pilots to streamline MI cancellation based on Loan-to-Value (LTV) ratios could impact persistency, though management views near-term impact as minimal as current rules already allow cancellation.
• Reinsurance Pricing Softening: Abundant capacity, including from third-party capital providers, is putting downward pressure on rates, particularly in property and casualty reinsurance, potentially compressing margins.
• Geopolitical Exposure: Significant exposure to the Middle East via Marine War Breach coverage presents inherent risks, though management considers the pricing adequate for the risk taken.
• Bermuda Tax Credit Uncertainty: The future of Bermuda’s Qualified Reinsurance Transaction Credits (QRTCs) is subject to OECD and government negotiations; potential loss of these credits would impact the effective tax rate and profitability.
• Interest Rate Environment: While higher rates support mortgage persistency, they constrain new origination volume. Conversely, rising interest rates provide a tailwind for net investment income due to the short duration of the fixed-income portfolio.

Q: Analysts asked about the sustainability of the aggressive share buyback program and whether it signals excess capital or debt-funding concerns. / A: CFO Francois Morin confirmed that buybacks are funded from a general pool of capital, partially utilizing incremental debt raised earlier. He stated that while rating agencies are supportive, the company carefully manages its capital cushion. Buybacks are opportunistic based on stock price attractiveness, and management expects to return even more capital if growth opportunities remain limited.

Q: Discussion focused on the strategic direction for casualty lines, noting conflicting signals about capital inflows versus growth opportunities. / A: CEO Nicolas Papadopoulo clarified that while primary casualty rates have decelerated to roughly lost-cost trend, absolute returns still meet ARCH's thresholds. Growth opportunities are clearer in Insurance (middle-market E&S, construction) than in Reinsurance, where terms and conditions remain less favorable due to abundant third-party capital supply keeping prices too high.

Q: Questions arose regarding the impact of recent UK riots and French protests on operational performance and claims. / A: Management stated that losses from European civil unrest are de minimis and not material to the fourth-quarter outlook. This highlights the diversification of ARCH's catastrophe exposure and the limited impact of localized political instability on their global portfolio.

Q: Analysts sought clarity on the long-term viability of Bermuda tax credits (QRTCs) and their role in capital planning. / A: Morin emphasized that QRTCs are a sustainable, structural benefit rather than a one-time event, with expected increases in percentage basis in 2027. However, he noted uncertainty regarding OECD developments. Internally, the company runs capital models both with and without these credits to ensure resilience against potential regulatory changes.

Q: Inquiry into the specific contribution of Iran-related Marine War Breach premiums to financial metrics. / A: Morin explained that the Iran conflict drove significant premium inflows in the Insurance segment, which was the primary driver for the improvement in the ex-cat loss ratio. Catastrophe losses attributed to the conflict were substantial ($234M total CAT losses, with a large portion linked to this region), but the premium earned adequately compensated for the risk, supporting the view that geopolitical risks can be priced attractively.
