MGIC Investment: a solid insurer, priced about right

MGIC insures lenders against losses on low-down-payment residential mortgages through its main subsidiary, Mortgage Guaranty Insurance Corporation. The business earns premiums for taking on mortgage-credit risk, invests the float, and leans on reinsurance and a capital cushion required under GSE rules to absorb stress losses. At $28.48 the company is profitable, well capitalized and buying back stock, and the question is simply whether that's already priced in.

At $28.48 on September 25, 2026, the shares trade 3.5% below my triangulated Base value of $29.50, an upside of 3.6%. The Bear value of $22 is 22.8% below the price. For a mortgage-credit insurer, the framework's required margin of safety is 25%, which puts the maximum buy price at $22.13. The shares sit about 29% above that level. Existing holders are collecting a covered dividend and ongoing buybacks; new money doesn't yet get a discount.

What MGIC is

MGIC is one of the largest private mortgage insurers in the U.S., with an estimated 19.4% share of the private mortgage insurance market in 2025. It insures lenders and government-sponsored entities against borrower default on eligible low-down-payment loans, manages risk transfer through reinsurance, and has to maintain capital under GSE eligibility requirements known as PMIERs. The business is long-lived and recurring, but it is concentrated in one correlated exposure: the health of the U.S. housing and employment cycle.

Credit quality is currently a real strength. 45% of primary risk in force carries borrower credit scores of 760 or above, with only 2% below 660. Persistency fell to 83.3% from 84.7% a year earlier as refinancing picked up, and net premium yield declined to 31.3% from 33.0%, partly reflecting reinsurance costs and portfolio mix. Nothing here signals a business-model change; it remains a mortgage-credit insurer with a strong current book.

The latest quarter

Which numbers matter for a mortgage insurer

Operating cash flow or generic free cash flow isn't the right lens for an insurer. The hardest honest metric here is reported common book value per share, read together with normalized earnings and return on equity. Q2 GAAP net income of $182.1 million was very close to adjusted net operating income of $183.7 million, so this analysis gives priority to the GAAP figure and treats the adjusted number as a cross-check rather than the primary input. Tangible book value per share, after the AOCI adjustment, was $25.08.

Simple annualization of H1 diluted EPS gives $3.24; annualizing Q2 alone gives $3.44. A conservative normalized EPS range of $3.00 to $3.50 is used, midpoint $3.25, allowing for policy runoff, premium yield pressure and claims variability against a strong recent run.

Shares and capital return

Shares outstanding fell 11.4% year over year to 206.6 million at Q2-end, driven by real buybacks rather than a share-class quirk: 6.6 million shares for $176.6 million in Q2 alone, plus another 1.5 million for $42.4 million through late July. The board authorized a further $750 million of repurchases through the end of 2028. The company also carries $650 million of 5.25% notes due 2028. Buybacks support per-share book value and EPS today, but future pace depends on capital needs and board discretion, so it shouldn't be extrapolated indefinitely.

Primary valuation: justified price to book value

The Base multiple sits intentionally above the cited long-run median of roughly 1.02x book, because current profitability, book growth and capital return are stronger than that historical average; this is a judgment, not a company forecast. The primary Base value is about $30.10.

Secondary valuation: normalized price to earnings

An 8x to 10x range gives $26.00 to $32.50. This is an independent earnings-based cross-check, not anchored to book value; it may overstate value if current investment income or low claims prove to be above mid-cycle levels.

Historical cross-check

A third-party historical reference puts MGIC's five-year median price to book near 1.02x, with a range of roughly 0.77x to 1.30x. Applied mechanically to $24.27 book value per share, the median implies about $24.75 and the top of the range about $31.55. At $28.48, MTG trades at 1.17x reported book and 1.14x tangible book, inside the historical band but above the median, without adjusting for today's higher profitability, capital rules or portfolio mix.

Valuation triangulation

Rounded working fair value used throughout this analysis is $29.50. The book and earnings methods agree within 3%; the historical reference is about 16% more conservative and is treated as a smaller-weight check rather than a primary input, since it isn't synchronized to today's cycle.

What is the market already pricing in?

At $28.48 the market pays about 8.76x normalized earnings and 1.17x book. Those multiples say investors expect MGIC to keep earning above a distressed insurer's return and to preserve the current capital cushion, while still assigning some discount for cyclical housing and regulatory risk. No reverse DCF is used, since price-to-book and normalized earnings are the sector-correct valuation engines for a regulated, capital-dependent insurer.

Bear, base and bull scenarios

Double-pessimism control: the Bear case combines lower earnings and a lower book multiple deliberately, because a recession would plausibly worsen both claims and perceived capital risk at once; no separate blanket recession haircut is layered on top.

The probability-weighted value is $28.93 ($22 × 25% + $29.50 × 55% + $36 × 20%), close to and slightly above the current price.

Sensitivity: normalized EPS and P/E

How the buy price is set

A 25% margin of safety fits a profitable insurer with a strong current capital position but concentrated exposure to housing, employment, borrower credit and long-tail claims: higher than a low-volatility compounder would need, lower than a distressed or opaque insurer would require. Applied to the $29.50 Base value, that gives a maximum buy price of $22.13, with the strongest opportunity below $22. At $28.48 the shares trade about 28.7% above that ceiling.

Dividend

The board declared a quarterly dividend of $0.17 per share, an annualized run rate of $0.68 and an indicated yield of about 2.39% at the current price. Q2 repurchases plus dividends returned capital equal to 124% of net income for the quarter. Repurchases, not the dividend, are the larger part of the capital-return story, and both remain subject to insurer capital needs and regulatory limits. Dividend growth is not assumed in the valuation.

Reasons to own MTG

• Scale and share. An estimated 19.4% share of the U.S. private mortgage insurance market as of 2025.
• Capital strength. $2.7 billion of PMIERs excess and $930 million of holding-company liquidity at quarter-end.
• Strong recent profitability. $182.1 million of Q2 net income and 9.8% year-over-year book value growth.
• Credit mix. 45% of risk in force carries 760+ credit scores, with meaningful reinsurance protection.
• Shrinking share count. Buybacks that reduce shares outstanding can compound per-share value when executed below intrinsic worth.
• Earnings support. The stock trades below 9x estimated normalized earnings.

What could go wrong?

• Housing and employment stress. A U.S. recession, rising unemployment or falling home prices can increase delinquencies and claims.
• Persistency risk. Refinancing and housing turnover can reduce policy persistency, premium yield and new insurance written.
• Competition. FHA pricing and eligibility, along with other private insurers, can intensify competitive pressure.
• Regulatory risk. Changes to GSE charters, PMIERs rules or reinsurance eligibility could reduce distributable capital.
• Concentration. Mortgage insurance is one correlated U.S. housing-credit system; benign historical loss experience may not predict a severe stress period.
• Capital allocation. Buybacks at an excessive valuation, or while capital buffers are actually needed, can destroy value.

Management execution

Management has sustained profitability, grown book value per share, returned capital through buybacks and dividends, and extended reinsurance protection, including a $400 million subsidiary dividend to the holding company this quarter that supported parent liquidity. The framework does not independently verify a multi-year guidance track record, and a high buyback pace can destroy value if executed above intrinsic value or if capital is later needed for stress. Assessment: positive but not exceptional; moderate confidence.

Stock Analyza scorecard

Business quality score is 74/100: strong capital and franchise economics, offset by housing-cycle and regulatory exposure. The valuation score is 58/100: profitable and inexpensive on earnings, but only a modest discount to estimated value.

Confidence score

The main limitation is the difficulty of estimating through-cycle mortgage claims and capital outcomes, not a lack of current reported data.

What I would watch from here

Review after every quarterly filing and immediately after any material PMIERs, reinsurance or GSE eligibility update. No earnings-calendar catalyst substitutes for monitoring credit and capital indicators directly.

The three most important thesis breakers

1. Meaningful deterioration in delinquencies or credit quality.
2. Book value declining rather than compounding.
3. PMIERs capital headroom shrinking toward the eligibility threshold.

Adversarial review

The first draft's arithmetic mostly reconciled: the price to book and price to earnings multiples, the justified base values, and the triangulation all check out. One number was wrong. The probability-weighted scenario value was stated as $28.33, but the draft's own scenarios and probabilities ($22 × 25% + $29.50 × 55% + $36 × 20%) actually sum to $28.93. The corrected figure is used throughout this article; it doesn't change the conclusion, since it's still close to, and now slightly above, the current price.

The strongest counter-thesis is that current earnings may be closer to a cyclical peak than the framework's normalized $3.25 EPS assumes, and that the market's roughly 1.17x book valuation could understate losses that would emerge in a severe housing downturn. At normalized EPS of $3.00 and 8x earnings, value would be $24; combined with a book multiple near 1x, that points to a $22 to $24 stress range, which challenges the Base case but is already substantially represented in the stated Bear scenario.

Audit limitations: the historical price-to-book median comes from a secondary data provider rather than a fully synchronized primary dataset, and exact Q2 debt carrying value, full-period guidance and multi-year industry claims scenarios weren't independently reconstructed. These are disclosed limits that don't change the Hold conclusion, but they keep the confidence grade at C rather than A or B. The publication gate status is PASS_WITH_WARNING.

Final verdict: hold at $28.48, watchlist for a better entry

MGIC is a profitable, well-capitalized mortgage insurer with strong capital returns, but a small estimated upside doesn't compensate for housing-cycle risk at the current price. The main thesis breaker is a meaningful deterioration in delinquencies, book value or PMIERs capital headroom.

Verdict: HOLD at $28.48. Triangulated Base value $29.50, upside 3.6%, Confidence C (17/25). Required margin of safety 25%, maximum buy price $22.13.

For an existing holder, the covered dividend and ongoing buybacks support holding while book value and credit quality stay intact. New money waits for $22.13 or below, or for a meaningful discount to book value without deterioration in credit or capital.
