Business Overview

NMI Holdings, Inc. is a private mortgage insurer providing credit enhancement solutions to lenders and borrowers across the United States. The company generates revenue primarily by writing and managing mortgage insurance (MI) policies that protect lenders against borrower default, with its business centered on new insurance written (NIW) and a growing portfolio of primary insurance in force. Major segments include insurance operations, investment income, and risk transfer through reinsurance, with a customer base of over 1,700 lending institutions.

Performance Analysis

NMIH posted another quarter of record results, driven by both top-line and bottom-line expansion. Total revenue reached a new high, supported by $16 billion in NIW and a primary insurance in force portfolio that has now surpassed $227 billion. Revenue grew 8.1% year over year, reflecting both portfolio expansion and stable net yield metrics. Investment income also contributed, rising sequentially and year over year, while expenses remained tightly managed with an expense ratio below 20%.

Credit performance remains a core strength. The default rate held at 1.16%, with defaults ticking down slightly quarter over quarter. Claims expense dropped meaningfully, and favorable reserve development persisted, reflecting a robust labor market and strong borrower equity. Share buybacks continued, with $31.4 million repurchased in the quarter and $167 million of capacity remaining.

• Persistency and Portfolio Quality: 12-month persistency was stable at 81.4%, supporting net premium consistency and high-quality risk retention.
• Expense Control: Underwriting and operating expenses remained flat, with no major cost headwinds anticipated near term.
• Capital Strength: Excess available assets of $1.6 billion provide ample buffer above risk-based requirements, enabling ongoing capital return flexibility.

Overall, NMIH’s financial delivery is underpinned by disciplined risk selection, robust portfolio growth, and a focus on long-term capital efficiency.

Executive Commentary

Strategic Positioning

1. Embedded Growth Engine Drives Outperformance

NMIH’s “pull to par” dynamic remains a structural advantage. The company’s share of new business production continues to outpace its share of industry insurance in force, fueling portfolio growth well above peer averages. Over the past four years, insurance in force grew 49% versus 13% for the rest of the industry, highlighting ongoing market share gains and a differentiated customer value proposition.

2. Disciplined Risk and Pricing Framework

Management maintains a proactive stance on risk selection, pricing, and reinsurance. The company leverages granular underwriting, rate GPS, and reinsurance tools to shape portfolio quality and returns. Industry competition remains rational, with no evidence of irrational pricing or underwriting drift, especially in the core business. Management’s focus is on balancing customer support with long-term shareholder value.

3. Flexible Reinsurance and Capital Management

Diversified reinsurance sourcing and robust capital position underpin NMIH’s risk management. The company favors traditional reinsurance for flexibility and execution speed, but maintains optionality to return to the capital markets for insurance-linked notes (ILN) when conditions warrant. Excess capital supports both organic growth and ongoing buybacks, with $167 million repurchase capacity remaining.

4. Constructive Credit and Housing Backdrop

Strong national home price appreciation and resilient employment trends underpin credit quality. While some regional pressure persists in Sunbelt and Mountain West markets, overall borrower performance remains robust. Favorable macro conditions continue to drive lower-than-expected defaults and positive reserve development, with no signs of emerging credit strain in recent vintages.

Key Considerations

This quarter highlights NMIH’s ability to deliver steady growth and capital returns while maintaining strong credit discipline and operational efficiency. The company’s outperformance is rooted in a high-quality insured portfolio, constructive industry dynamics, and a proactive approach to capital allocation.

Key Considerations:

• Market Share Momentum: NMIH’s NIW and insurance in force growth outpace industry, driven by lender relationships and service model strength.
• Stable Yield and Persistency: Core net yield and persistency rates remain steady, supporting revenue predictability even as refinancing activity fluctuates.
• Expense Management: Operating costs remain flat, with no major increases anticipated, preserving margin strength.
• Capital Return Optionality: Active buybacks and a strong capital base provide flexibility for future returns or strategic investments.
• Macro Sensitivity: Management remains vigilant to macroeconomic shifts, with a watchful eye on potential credit normalization and housing market changes.

Risks

Macro risk remains the primary uncertainty, with potential for rising defaults if employment or home prices weaken. Seasonality is expected to push default rates modestly higher in the second half of the year, and regional housing pressures could intensify. Competitive dynamics and pricing discipline are stable for now, but any shift toward aggressive underwriting could pressure future returns. Regulatory changes, while supportive in the long term, are unlikely to impact near-term business fundamentals.

Forward Outlook

For Q3 2026, NMIH did not provide explicit quantitative guidance but signaled:

• Expectations for continued growth in insurance in force and NIW, supported by a resilient housing market.
• Anticipation of seasonally higher default rates in the back half of the year, reflecting typical credit cycles.

For full-year 2026, management did not update formal guidance but reiterated confidence in the embedded growth engine and capital return program. Key factors highlighted include continued portfolio expansion, stable credit conditions, and proactive risk management.

• Strong capital position to support both organic growth and opportunistic buybacks.
• Ongoing monitoring of macro and housing market trends to adjust risk selection and pricing as needed.

Takeaways

NMIH’s Q2 results reinforce its position as a disciplined growth compounder with a robust capital foundation and a high-quality insured portfolio.

• Outperformance Rooted in Portfolio Growth: Insurance in force and NIW growth continue to surpass peers, reflecting a differentiated customer franchise and embedded structural advantage.
• Risk and Capital Management Remain Core Strengths: Prudent underwriting, expense control, and flexible reinsurance sourcing support both growth and capital return ambitions.
• Watch for Macro Inflections: Investors should monitor for signs of credit normalization, shifts in housing fundamentals, or changes in industry pricing discipline as the cycle matures.

Conclusion

NMI Holdings delivered another record quarter, with growth and profitability fueled by a high-quality insured portfolio, disciplined risk management, and active capital return. The company’s embedded growth engine and stable credit trends position it well, though investors should stay alert to evolving macro and competitive risks.

Industry Read-Through

NMIH’s results signal a broadly constructive environment for private mortgage insurers, marked by stable credit, rational competition, and resilient borrower performance. The company’s commentary suggests that industry-wide pricing discipline is holding, with no material drift toward riskier underwriting. Reinsurance markets remain favorable, with ample capacity and attractive terms, benefiting the sector’s capital efficiency. However, regional housing pressures in the Sunbelt and Mountain West, as well as the potential for macro-driven credit normalization, are watchpoints for all mortgage credit providers. Long-term, the sector’s growth will hinge on housing supply initiatives and sustained borrower demand, but near-term, disciplined risk management and capital allocation remain the key differentiators.
