RDN — Radian Group Inc

Leading US private mortgage insurer. AGI Score 5/10. Aggressive buybacks (-27% shares). Trading at 0.93x book. | Analysis date: 2026-03-13

Why are we looking at this?

Radian is a mortgage insurance cash machine: $583M net income on $1.2B revenue (49% net margin) with almost zero CapEx. Shares have been reduced from 153M to 135M (-12%) in just 2 years, with $431M spent on buybacks in FY2025 alone. The company just acquired Inigo (Lloyd's specialty insurer) to diversify beyond mortgage insurance. At 0.93x book, you're buying the insurance book near liquidation value while the company aggressively returns capital. The question: is mortgage insurance durable in an AGI world, and does the Inigo acquisition help or hurt?

1. The Business

Radian is a leading US private mortgage insurer. When homebuyers put down less than 20%, lenders require private mortgage insurance (PMI). Radian insures the lender against default. This is a regulatory mandate — as long as people buy homes with <20% down, Radian has a market.

Key Metrics

The Beauty of Mortgage Insurance

Near-zero CapEx business. Revenue is premiums collected on existing insurance. Costs are claims paid when borrowers default. In good times, this business prints money. $583M net income on minimal capital needs = extraordinary ROE. The entire business is essentially a balance sheet with reserves.

Inigo Acquisition (Feb 2026): Radian acquired Inigo, a Lloyd's specialty insurer, to diversify into property, casualty, and specialty insurance. This moves Radian from pure mortgage insurance to a multi-line insurer.

YearRevenueNet IncomeShares (M)Buyback
FY2022$1.19B$743M~160M($400M)
FY2023$1.18B$603M153M($133M)
FY2024$1.21B$604M148M($225M)
FY2025$1.20B$583M135M($432M)

The Buyback Machine

This is the most aggressive buyback story in the batch. Shares reduced from ~160M to 135M in 3 years (-15.6%). In FY2025 alone, $432M in buybacks — 74% of net income returned through buybacks. With $3.08% dividend yield on top, total shareholder return is massive.

At this buyback rate, in 5 years shares could be below 100M, meaning EPS doubles even with flat earnings.

4. Working Backwards from 10x

What would 10x ($330/share, ~$45B market cap) require?

Verdict: NOT a 10x candidate but an excellent compounder. Buybacks + dividends + stable earnings = likely 12-18% annual returns. This is a Buffett-style "wonderful business at a fair price."

5. AGI Impact

Positives

  • Mortgage insurance is regulatory mandate — AGI doesn't change this
  • AGI improves risk assessment → better pricing → higher margins
  • Claims processing automation reduces costs
  • Housing demand is physical — people need homes regardless of AGI

Negatives

  • AGI could enable new risk-sharing models that bypass traditional MI
  • Competitive advantages from data/analytics erode if everyone has AGI
  • Remote work → housing demand shifts could increase or decrease MI volume
  • Regulatory changes (GSE reform) could restructure the market

6. Floor Price & Assessment

Book Value / Share$35.29Zero goodwill — all tangible
Trough Earnings Floor$20-25In housing crisis, NI could drop to $200M. 200M ÷ 135M × 15x = $22
Liquidation Floor$28-32Book value is highly liquid (investments + reserves)
Normalized Earnings$35-45$580M NI ÷ 135M shares × 8-10x = $34-43

RDN at $33 is fairly priced. P/E of 7.5x on stable earnings with aggressive buybacks. Floor is $20-25 in a housing downturn. The key risk is a housing crisis that spikes default rates.

Rating: WATCHLIST — Buy at $22-25. At that price, you're buying at trough valuation with the buyback machine still running. The 3% dividend provides income while you wait.
