Unum (UNM) Stock Could Be 45% Undervalued After LTC Reinsurance Deal

Simply Wall St·11/04/2026 05:39:59
Listen to the news

Unum Group has delivered a powerful 5 year run, which puts fresh focus on whether the current share price is properly backed by the returns the insurer earns on its capital. With the stock now reflecting years of gains and a major long term care reinsurance deal completed, investors are asking how much of Unum's capital efficiency story is already in the price.

  • Over the past 5 years the stock has returned about 309.4%, so a lot now hinges on whether the underlying returns on Unum's capital can justify that kind of compounding.
  • The recent US$3.8b long term care reinsurance transaction reduces more than US$7b of statutory reserves, which may support a cleaner balance sheet and change how efficiently Unum can redeploy capital into higher returning areas of the business.

Is Unum Group Still Cheap on Excess Returns?

The Excess Returns model looks at how much profit Unum Group generates above the return that equity investors typically require. With a book value of $68.28 per share and a stable book value estimate of $75.92 per share, the framework suggests Unum could keep compounding its equity base at a measured pace. A stable EPS estimate of $8.62 per share against a cost of equity of $5.49 per share implies an excess return of $3.12 per share, supported by an average return on equity of 11.35%.

Because that excess is positive in the model and the stock trades at $91.03, the setup points to a business that the market may not fully credit for its projected returns on capital. The recent US$3.8b long term care reinsurance deal and related accounting hit help explain why the price can sit below what these implied excess returns support.
