Customers
Enact sells primarily to mortgage originators across the United States, including national banks, non-bank lenders, mortgage bankers, community banks, and credit unions. These customers buy mortgage insurance to support loan origination, manage credit risk, and meet investor or GSE requirements on higher loan-to-value mortgages. The business is relationship-driven, with broad lender coverage and a small number of large customers contributing meaningful volume.

Strategy
Enact's strategy centers on differentiated underwriting, strong capital management, and disciplined risk-adjusted growth in U.S. mortgage insurance. The company also uses CRT and a conservative investment portfolio to reduce volatility, preserve capital, and support shareholder returns through buybacks and other capital actions.
Better underwriting and service help win lender share in a competitive, relationship-driven market.
PMIERs compliance and capital strength are required to keep writing GSE-related mortgage insurance.
Risk transfer lowers earnings volatility and improves capital efficiency under stress scenarios.
Buybacks are a key lever for value creation once policyholder support and growth needs are funded.
Geography
Enact is overwhelmingly a U.S.-focused business, with sales and marketing, underwriting, and customer relationships spread throughout the United States. Its main operating subsidiary is U.S.-domiciled, while Enact Re is Bermuda-based and provides reinsurance support; the company also has a small run-off block tied to Mexico that is immaterial. Geography matters mainly through U.S. housing-market conditions, state-level concentrations, and regulatory oversight rather than international revenue diversification.
Risks
The business is exposed to mortgage credit cycles, home-price declines, and unemployment-driven claim severity because its revenue depends on insured loan performance. It also faces regulatory and eligibility risk from PMIERs and state insurance rules, plus concentration risk from a relatively small set of large lender customers and operational/cybersecurity risk tied to its systems and data flows.
