NMI Holdings (NMIH) Q2 2025: Book Value Per Share Up 16% as Expense Ratio Hits Record Low
NMI Holdings delivered record book value per share growth and maintained a disciplined cost structure, underscoring robust portfolio quality and operational leverage. Management’s tone was notably confident, even as they flagged pockets of housing market normalization and persistent macro uncertainty. Investors should watch for continued capital returns and evolving risk management as the housing cycle matures.
Summary
- Expense Leverage Inflection: Operating expense ratio reached a new low, amplifying profit scalability.
- Portfolio Quality Holds: Default rates and credit performance remain best-in-class despite regional housing softening.
- Capital Return Steadiness: Share repurchase cadence signals ongoing confidence and flexibility in capital deployment.
Performance Analysis
NMI Holdings posted record revenue and book value per share, driven by sustained growth in its insured portfolio and disciplined cost management. Primary insurance in force climbed to $214.7 billion, up 5% year-over-year, as new insurance written (NIW) remained healthy at $12.5 billion. Persistency, which measures the percentage of insurance policies retained over a twelve-month period, held at 84.1%, supporting embedded value growth and revenue durability.
Expense efficiency was a clear highlight, with the operating expense ratio dropping to 19.8%, the lowest in company history. This improvement, paired with stable net premiums earned, drove robust bottom-line profitability. Investment income continued its steady rise, reflecting prudent reinvestment in a favorable rate environment. Credit quality remained strong, with the default rate declining to 1%, and claims expense well-contained. The company repurchased $23.2 million of stock in the quarter, retiring shares at an average price of $36.90, and retains substantial buyback capacity.
- Embedded Value Growth: Persistency and NIW gains fueled a record $32.08 book value per share (excluding unrealized gains/losses), up 16% year-over-year.
- Operational Leverage: Lower expense ratio and stable premiums highlight scalable business model advantages.
- Risk Profile Stability: Default rates and claims expense trends affirm disciplined underwriting and favorable borrower profiles.
Overall, the quarter showcased NMIH’s ability to compound value through disciplined risk selection, cost control, and capital allocation, even as management acknowledged housing market normalization in select geographies.
Executive Commentary
"We have an exceptionally high-quality insured portfolio covered by a comprehensive set of risk transfer solutions, and our credit performance continues to stand ahead.

Adam Pulitzer, President and Chief Executive Officer

Strategic Positioning
1. Portfolio Quality and Risk Management
NMIH’s insured book remains high-quality, with a declining default rate and resilience across most geographies. Management emphasized proactive risk selection and pricing discipline, leveraging granular tools to manage exposures across 950 metropolitan statistical areas (MSAs, regional housing markets). The firm’s use of risk transfer solutions, including quota share and excess of loss (XOL) reinsurance, is fully placed for 2025 and 2026, insulating future earnings from adverse credit events.
2. Operating Efficiency and Expense Control
Expense discipline is a structural advantage, with the expense ratio at a record low. Management cited typical seasonal factors (lower FICA and 401k expenses post-Q1) but attributed the improvement primarily to operational rigor and scale. This efficiency enables NMIH to maintain competitive pricing while protecting margins, even as revenue per policy faces industry-wide pressures.
3. Capital Allocation and Shareholder Returns
Capital return remains a core pillar, with steady share repurchases and $281 million in remaining buyback capacity. Management signaled flexibility to accelerate or pause buybacks based on market valuation and risk environment, but current pacing (~$25 million per quarter) is expected to persist. The robust capital position, with $1.3 billion in excess available assets, supports both risk-based regulatory requirements and opportunistic capital deployment.
4. Navigating Housing Market Normalization
Management acknowledged regional housing softening, particularly in parts of Florida, Texas, and the Mountain West—areas that saw outsized price appreciation during the pandemic. However, NMIH views the market as moving toward equilibrium, with national demand drivers (employment, demographics) intact. The company’s risk tools and pricing flexibility allow it to adapt exposures as local conditions evolve, limiting the need for reactive strategy shifts.
Key Considerations
This quarter reinforced NMIH’s defensive positioning and operational leverage, while also surfacing early signals of housing cycle normalization that could shape forward risk and growth dynamics.
Key Considerations:
- Persistency as a Value Driver: Elevated persistency rates amplify embedded value and revenue durability, supporting premium growth even in a slow origination environment.
- Credit Performance Outperformance: Default cures benefited from strong labor markets and borrower equity cushions, but seasonality and macro shifts could test this trend in H2.
- Expense Ratio Sustainability: Record-low expense ratio reflects scale benefits, but investors should monitor for upward drift as business investments or inflation pressures return.
- Regulatory and Policy Watch: Management does not expect recent FHFA proposals or MI tax deduction changes to materially impact the business, but regulatory shifts remain a background risk.
Risks
Regional housing market normalization, especially in previously overheated markets, could pressure future credit performance and NIW growth. Persistent macro uncertainty, including labor market softening or policy changes, may challenge default cure rates and premium revenue. Regulatory developments, while currently benign, require ongoing vigilance given the company’s reliance on GSE (government-sponsored enterprise) channels and evolving housing policy.
Forward Outlook
For Q3 2025, NMIH indicated:
- Continued disciplined capital return, with ~$25 million in quarterly share repurchases as a baseline assumption.
- Stable risk transfer coverage, with no need for incremental reinsurance actions unless market conditions shift.
For full-year 2025, management did not formally update guidance, but:
- Portfolio growth and credit performance are expected to remain strong, barring significant macro deterioration.
Management highlighted several factors that could influence results:
- Seasonal patterns in default cures may soften in the second half as tax refund benefits wane.
- Regional housing trends and borrower behavior will be closely monitored for emerging risk signals.
Takeaways
NMIH’s Q2 performance underscored its ability to drive value through operational discipline, strong credit management, and steady capital returns.
- Book Value Compounding: Persistency, portfolio growth, and cost control combined for record book value per share, reinforcing intrinsic value creation.
- Risk Management Rigor: Proactive underwriting and reinsurance coverage position the company to absorb localized housing volatility without major disruption.
- Capital Flexibility Ahead: The company’s approach to buybacks and capital deployment signals both confidence and readiness to adapt if market conditions shift.
Conclusion
NMI Holdings delivered a quarter marked by operational excellence and prudent risk management, with record book value growth and a standout expense ratio. The company remains well-positioned to navigate evolving housing dynamics and continue compounding shareholder value, though vigilance on regional risk and macro signals is warranted.
Industry Read-Through
NMIH’s results highlight the benefits of scale and disciplined expense management in the private mortgage insurance sector, especially as the U.S. housing market transitions from pandemic-driven extremes toward normalization. Persistency and credit performance remain industry-wide tailwinds, but regional housing softening, particularly in Sunbelt and Mountain West markets, could become a broader challenge if supply outpaces demand or price declines accelerate. Capital return strategies and risk transfer programs are likely to remain central competitive levers for mortgage insurers as regulatory scrutiny and macro uncertainty persist. Investors in the mortgage finance and housing sectors should closely monitor persistency, expense leverage, and regional credit signals as key differentiators in the quarters ahead.
