Read MoreHide Full Article

Key Takeaways

  • NMIH's mortgage insurance business generates revenues and gains from higher insurance-in-force.
  • Recurring premiums, disciplined underwriting and risk-based pricing support cash flow and profitability.
  • Strong housing demand and home price appreciation position NMIH for long-term growth.

NMI Holdings, Inc. (NMIH - Free Report) is a pure-play private mortgage insurance company that operates through its primary subsidiary, National Mortgage Insurance Corporation (“NMIC”). Mortgage insurance is NMI Holdings' core business and generates virtually all of its revenue. 
NMI's mortgage insurance business benefits from growth in purchase mortgage originations, higher insurance-in-force and increased adoption of private mortgage insurance relative to government-backed mortgage programs.

Mortgage insurance creates a recurring stream of premium revenues for NMI Holdings because borrowers or lenders pay insurance premiums over the life of the insured loans. As NMIH writes more new policies and grows its insurance in force, earned premiums increase, providing predictable cash flows. Mortgage insurance also allows NMIH to leverage disciplined underwriting and risk-based pricing to generate attractive underwriting profits. By focusing on borrowers with strong credit profiles and appropriately pricing risk, NMIH has historically maintained low claim rates and favorable loss ratios.

Mortgage insurance further positions NMI to benefit from favorable housing market trends. Strong home purchase activity, rising first-time homebuyer demand, home price appreciation and healthy employment typically increase the number of insured mortgages while keeping credit losses low. These factors contribute to higher insurance-in-force, expanding premium revenues, improved profitability and stronger returns on equity.

NMI Holdings has established itself as a well-capitalized, technology-focused mortgage insurer with disciplined underwriting and strong risk management. Its earnings are closely tied to the health of the U.S. housing market and mortgage origination activity. Mortgage insurance provides NMI Holdings with a scalable, capital-efficient business model that generates investment income and long-term growth opportunities, while disciplined risk management and reinsurance help mitigate credit losses across housing market cycles.
