SPNT Q3 2025: Insurance Segment Grows 49%, Underwriting Discipline Drives Low Volatility Returns

October 31, 2025 | By EarningsIQ Research

SiriusPoint’s third quarter marked a decisive acceleration in insurance and services, with a 49% surge in gross written premium and a continued track record of low-volatility, disciplined underwriting. Management’s focus on portfolio mix, risk selection, and MGA rationalization is delivering sustainable returns, while capital actions signal further balance sheet strength ahead. With strategic disposals and capacity partnerships locking in future earnings, SiriusPoint is positioning for durable, high-quality growth even as industry cycles shift.

Summary

• Insurance Segment Momentum: Insurance and services premium expanded sharply, reflecting targeted risk selection and mix shift.
• MGA Rationalization Unlocks Value: Asset sales boost book value and deepen long-term capacity relationships with key partners.
• Forward Capital Flexibility: Preference share redemption and leverage reduction set the stage for enhanced credit profile and lower costs.

Performance Analysis

SiriusPoint delivered a robust third quarter, with consolidated results underscoring profitable growth and a disciplined risk approach. The core combined ratio of 89.1% led to an 11% year-over-year increase in underwriting income, with no catastrophe losses impacting the period. Operating return on equity reached 17.9%, well above the company’s 12% to 15% through-cycle target, and year-to-date operating ROE stands at 16.1% despite elevated catastrophe losses earlier in the year.

The insurance and services segment was the standout, posting a 49% increase in gross written premium to $562 million, driven by accident and health, surety, and attritional property lines. This business now accounts for 45% of segment gross written premium and acts as a volatility dampener due to its short-tail, low-correlation profile. The segment’s combined ratio improved by 2.3 points, reflecting better loss experience and lower expenses. Reinsurance saw a modest 2% decline in gross written premium, with a 3.3 point uptick in the combined ratio due to lower favorable prior year development. Investment income remained solid, supported by high-quality fixed income allocations and reinvestment yields above 4.5%.

• Insurance Segment Expansion: Gross written premium growth was broad-based, with accident and health lines providing stability and capital efficiency.
• Attritional Ratio Improvement: The seventh straight quarter of attritional loss ratio gains signals ongoing underwriting discipline and portfolio quality.
• Capital and Book Value Leverage: Book value per share rose 13% year-to-date, while upcoming MGA asset sales are set to further enhance equity and reduce leverage.

Service fee income and investment returns further diversified earnings, while the company’s BSCR ratio improved to 226%, reflecting strong capital adequacy ahead of planned preference share redemption.

Executive Commentary

Strategic Positioning

1. Insurance and Services as Growth Engine

The insurance and services segment has emerged as SiriusPoint’s primary engine for profitable growth, with double-digit premium expansion for six consecutive quarters. The accident and health division, accounting for nearly $1 billion in annualized gross premiums, plays a pivotal role as a “volatility shock absorber,” offering short-tail, low-volatility returns and insulation from traditional P&C cycles. Surety and other less-correlated lines further diversify risk and revenue streams, supporting consistent earnings even as broader market conditions fluctuate.

2. MGA Rationalization and Strategic Partnerships

Recent divestitures of Armada and Arcadian MGA stakes unlock $389 million in proceeds, crystallizing off-balance sheet value and delivering a per-share book value uplift of roughly $1.75. Critically, SiriusPoint has secured long-term capacity agreements with both MGAs on existing economic terms through 2030 and 2031, ensuring continued premium flow and underwriting alignment. This approach demonstrates the company’s disciplined capital allocation, focusing on scalable, seasoned MGA partnerships—90% of MGA premiums now derive from relationships older than three years.

3. Underwriting Discipline and Portfolio Volatility Reduction

Management’s focus on underwriting quality and portfolio mix has materially reduced volatility, as evidenced by 12 consecutive quarters of underwriting profits and 18 consecutive quarters of favorable prior year development. The attritional combined ratio improved 1.8 points year-over-year, with gains across loss, acquisition, and expense ratios. Catastrophe exposure has been structurally reduced through portfolio actions, resulting in lower loss ratios relative to peers and more predictable earnings power.

4. Capital Structure Optimization

The company’s capital plan is evolving with the pending redemption of $200 million in preference shares, funded by MGA sale proceeds. This move will reduce leverage from 31% to 24%, lower financing costs, and enhance SiriusPoint’s credit profile ahead of a rate reset in early 2026. The improved BSCR ratio and liquidity position provide flexibility to support further organic growth or opportunistic capital deployment.

5. Prudent Reserving and Earnings Quality

SiriusPoint’s reserving posture remains conservative, with new MGA relationships reserved above pricing projections and a strong record of favorable prior year development. The average duration of insurance liabilities stands at 2.8 years, and the company has completed multiple loss portfolio transfers to further insulate future earnings from legacy exposures.

Key Considerations

Strategic execution this quarter centers on portfolio quality, risk management, and capital discipline, enabling SiriusPoint to deliver on its best-in-class ambitions while navigating evolving market cycles.

Key Considerations:

• Insurance Mix Shift Drives Stability: Expansion in accident and health and surety lines reduces earnings volatility and increases capital efficiency.
• MGA Partner Selection and Seasoning: Focus on mature, long-term MGA relationships supports underwriting quality and minimizes early-stage risk.
• Capital Actions Enhance Flexibility: Preference share redemption and reduced leverage improve credit standing and lower future financing costs.
• Disciplined Growth in Reinsurance: Selective capital allocation in reinsurance, with caution in aviation and public D&O, reflects management’s focus on margin over volume.
• Investment Portfolio Remains Defensive: High-quality, investment-grade fixed income portfolio maintains yield while minimizing credit risk.

Risks

Key risks center on potential pricing pressure in casualty and reinsurance, particularly in aviation and public D&O, where SiriusPoint has already reduced exposure. Reliance on MGA partners introduces counterparty and operational risk, though the company’s seasoning and profit-sharing approach mitigates some of this. Regulatory change, macroeconomic volatility, and competitive dynamics in specialty lines could challenge margin sustainability. Preference share redemption execution and integration of new leadership at IMG also warrant monitoring.

Forward Outlook

For Q4 2025, SiriusPoint guided to:

• Premium growth more in line with year-to-date trends, moderating from Q3’s surge
• Continued focus on underwriting discipline and portfolio mix optimization

For full-year 2025, management reaffirmed its operating ROE target of 12% to 15% across the cycle:

• Expense ratio guidance remains at 6.5% to 7%

Management highlighted several factors that will shape results:

• Completion and integration of MGA asset sales and capacity agreements
• Capital redeployment and leverage reduction post-disposal

Takeaways

SiriusPoint’s Q3 performance validates its strategic shift toward low-volatility, high-return specialty underwriting, with the insurance segment’s breakout growth and prudent MGA rationalization at the core. Capital actions and risk selection discipline provide a strong foundation for future earnings quality and resilience.

• Insurance and Services Outperformance: Segment growth and mix shift are driving improved margins and return consistency, with volatility dampened by accident and health exposure.
• Capital and Partnership Actions Set Up Future Flexibility: Asset sales, preference share redemption, and long-term MGA agreements lock in value and support future growth.
• Watch for Margin Discipline and Cycle Navigation: Investors should monitor casualty and reinsurance pricing, as well as the impact of capital actions and new leadership at IMG, for signals on margin sustainability and growth trajectory.

Conclusion

SiriusPoint’s third quarter demonstrates the tangible benefits of underwriting discipline, portfolio mix management, and strategic capital deployment. With insurance and services now the clear growth lever and MGA rationalization unlocking value, the company is well positioned for durable, low-volatility returns in a shifting market landscape.

Industry Read-Through
