Is RDN a Buy or a Sell? The Bull and Bear Case (2026)

The most optimistic published target on RDN is $48.00, +31.2% from the $36.59 price as of August 2026. Getting there needs the following to work close to its best case, not merely to avoid going wrong.

The most pessimistic published target is $35.00, -4.3% from the current price. That is not a floor and not a forecast; it is roughly what one analyst thinks Radian Group is worth if the risks below bite instead of the drivers above.

The Specialty segment ran a ~93.0 percent combined ratio in the first half of 2026, which leaves thin margin before an underwriting loss, and Lloyd's syndicates carry catastrophe exposure that arrives in lumps rather than in trend lines. Syndicate 1301 writes property and specialty risk into a market that has been softening since the 2023 rate peak, so the ~1.4 times tangible equity Radian paid assumes pricing holds up reasonably well. Purchase accounting both flatters and distorts the first year in different places, and a clean run-rate will not be visible until 2027. Integration risk sits on top of a leadership change: Mike Weinbach took over as chief executive on August 13, 2026, Rick Thornberry departs at year end after nearly a decade, and the London business is being kept under its own management. On the mortgage side the credit cycle has begun to turn. Primary delinquencies rose to ~2.47 percent of loans at June 30, 2026 from ~2.27 percent a year earlier, and the 2021 and 2022 vintages are entering the years when defaults historically peak. First-half earnings leaned on reserve releases, visible in the ~33.0 percent combined ratio, and a rising default rate reverses that arithmetic quickly, because the same loans that release reserves on cure consume them on default. Rates cut both ways. A fall in mortgage rates would lift new insurance written but drag persistency below ~82 percent, shrinking the in-force book that generates the premium. Capital is tighter than it was: total debt of ~$1.345 billion at June 30, 2026 against ~$4.8 billion of equity, with ~$600 million of the purchase funded by that intercompany note out of Radian Guaranty, whose PMIERs excess available assets stood at ~$1.5 billion. Fannie Mae, Freddie Mac and the FHFA set those capital requirements and have revised them before.

The bear case deserves the same attention as the bull case, and usually gets less. If you are holding RDN already, the question is not whether these risks exist but whether any of them has moved from possible to actually happening in the reported numbers.

5 analysts cover RDN, with an average target of $43.80 (+19.7% against $36.59) and a split of 4 buy, 1 hold, 0 sell. Bear in mind sell-side ratings skew positive across the whole market, so that split is not a balanced vote. The full target table, the recent rating actions by firm, and how the consensus has shifted are on the RDN forecast and price target page.

• Revenue (TTM): ~$1.65 billion for the twelve months to June 30, 2026, up ~37.5 percent, against ~$1.197 billion in fiscal 2025, ~$1.206 billion in 2024 and ~$1.177 billion in 2023. The increase is acquired rather than organic: it represents roughly five months of Inigo, consolidated from February 2, 2026. Second-quarter revenue alone was ~$575 million, up ~93 percent year over year, on net premiums earned of ~$504 million (up ~115.7 percent) and net investment income of ~$70 million (up ~21.1 percent). First-half 2026 total revenue was ~$1.041 billion.
• Earnings and EPS: Net income of ~$536 million for the twelve months to June 30, 2026, down ~8.6 percent, for diluted EPS of ~$3.89 against ~$4.14 in 2025, ~$3.92 in 2024 and ~$3.77 in 2023. First-half 2026 net income was ~$240.0 million, split between ~$247.7 million from continuing operations and a ~$7.7 million loss from discontinued ones. The second quarter produced ~$118 million, or ~$0.87 diluted, from continuing operations, with adjusted diluted net operating income of ~$1.14 per share.
• Segment mix and operating metrics: In the first half of 2026 the Mortgage segment earned ~$474.5 million of net premiums at a ~33.0 percent combined ratio, while the Specialty segment earned ~$431.7 million at a ~93.0 percent combined ratio that still carries integration and purchase-accounting effects. Primary mortgage insurance in force reached a record ~$284 billion at June 30, 2026, up ~3 percent, on ~$75.4 billion of risk in force. New insurance written was ~$16.3 billion in the quarter, up ~14 percent. Persistency was ~82 percent, up ~70 basis points, and the primary default rate ~2.47 percent versus ~2.27 percent a year earlier.
• Balance sheet and regulatory capital: Total assets of ~$10.66 billion at June 30, 2026, up ~31 percent on the acquisition, with shareholders' equity of ~$4.8 billion and reserves for losses and loss adjustment expense of ~$1.91 billion. Total debt was ~$1.345 billion, up from ~$1.193 billion at year-end 2025, and ~$600 million of the Inigo purchase price came from a 10-year, 6.50 percent intercompany note issued by Radian Guaranty. Book value per share was ~$36.00, up ~8.5 percent year over year. Radian Guaranty held ~$1.5 billion of available assets above its PMIERs minimum.
• Capital return: The quarterly dividend is $0.255 per share, ~$1.02 annualised, costing ~$37 million a quarter, for a yield of ~2.79 percent at ~$36.59 and a payout ratio near ~26 percent of trailing EPS. Radian also repurchased ~2.2 million shares for ~$76 million in the second quarter of 2026, so buybacks ran roughly double the dividend. Share count stood at ~132.3 million as of August 5, 2026 and has been reduced steadily through repurchase over several years. Dividend and buyback capacity both depend on distributions up from Radian Guaranty, which are governed by state insurance law and PMIERs headroom.
• Market pricing: At ~$36.59 the shares carry a market capitalisation of ~$4.84 billion on ~132.3 million shares, inside a 52-week range of ~$31.50 to ~$41.05. The stock trades at ~9.0 times trailing EPS of ~$3.89, ~7.3 times forward estimates, and ~1.02 times book value per share of ~$36.00. Enterprise value to EBITDA is not a meaningful measure for an insurance holding company, since the operating line is underwriting result plus investment income rather than EBITDA, and the ~$1.345 billion of debt is holding-company financing rather than working capital.

Insurance holding companies are read on book value and return on equity, so the ~2.9 times sales multiple a screener prints for RDN carries almost no information about what the business is worth. At ~1.02 times book the stock sits at the low end of the ~0.9 to ~1.3 times range US mortgage insurers have generally occupied, while the forward multiple of ~7.3 times already embeds the mid-teens EPS accretion management guided to from Inigo. Whether the discount reflects the delinquency cycle, the ~93 percent specialty combined ratio, or the change of chief executive is the open argument.

Rather than asking whether RDN is a buy in the abstract, it tends to help to answer four questions:

• Thesis: do you believe the bull case above, and is it still true today?
• Time horizon: a single stock can be volatile, so a longer horizon absorbs more of the swings.
• Position sizing: a thesis can be right and the sizing still wrong; decide how much of your portfolio one name should be.
• Overlap: check whether you already hold RDN indirectly through an index or sector ETF before adding more.

Write the tripwires down before you need them. Deciding what would falsify your view is far harder once a position is moving against you.

• Bull case breaks if: The in-force book runs on persistency, not new sales stalls in the reported numbers rather than in the narrative around them.
• Bear case breaks if: the Specialty segment ran a ~93.0 percent combined ratio in the first half of 2026, which leaves thin margin before an underwriting loss, and Lloyd's syndicates carry catastrophe exposure that arrives in lumps rather than in trend lines fails to materialise over several reporting periods while the drivers keep compounding.
• Neither matters if: the position has grown large enough that being wrong would damage the whole portfolio. Sizing overrides the argument.
