BankUnited (BKU) Stock Looks Undervalued On Its 98% Three Year Run

Simply Wall St·08/24/2026 23:22:12
Listen to the news

BankUnited stock has almost doubled over the past three years, and the current Excess Returns intrinsic value estimate still points to a discount against the share price. For investors, the puzzle is whether this gap reflects a genuine margin of safety or simply model assumptions that are slower to adjust than the market.

  • BankUnited has delivered a 98.0% return over the past three years, which means anyone looking at the stock today is assessing it after a strong multi year run.
  • Future valuation can be influenced by how consistently BankUnited converts its loan book into durable earnings. Any shift in credit quality or funding costs may limit how much value investors are willing to ascribe to that earnings stream.
  • On Simply Wall St's checks, BankUnited screens as attractively priced in 5 out of 6 valuation tests. This suggests the broader indicators lean cheap despite the share price performance so far, as seen in the value score of 5.

The issue now is whether BankUnited's current share price already reflects most of this improvement or if the intrinsic value estimate still points to meaningful upside left on the table.

BankUnited delivered 23.5% returns over the last year. See how this stacks up to the rest of the Banks industry.

Is BankUnited a Bargain on Excess Returns?

The Excess Returns model estimates what BankUnited can earn on its equity after covering the cost of that equity. For BankUnited, the inputs indicate a bank that is expected to earn more on its capital than investors require, which supports a higher intrinsic value.

The model uses a book value of $41.55 per share and a stable book value estimate of $44.39 per share, with an average return on equity of 9.69%. On that base, stable EPS is estimated at $4.30 per share while the cost of equity is put at $3.29 per share. That gap produces an excess return of $1.01 per share, which feeds into an intrinsic value estimate of about $71.80 per share. Compared with the current share price, this implies BankUnited is trading at roughly a 35.5% discount and screens as undervalued on this measure.

On the Excess Returns approach, BankUnited stock currently appears undervalued relative to its estimated intrinsic value.

Where Does BankUnited Sit on Earnings?

The P/E ratio is a straightforward way to see what investors are paying for each dollar of BankUnited earnings. For a bank like BankUnited, which is analysed heavily on its earnings power, this multiple is a natural reference point.

BankUnited currently trades on a P/E of about 11.8x. That is very close to the broader Banks industry average of 11.8x and sits below the peer group average of 15.0x. The model based fair P/E for BankUnited is about 12.1x, which is only slightly above the current level.

This narrow gap suggests the market price is broadly in line with what would be expected once factors such as growth expectations, profitability, size and risk are taken into account. There is no clear signal of a large discount or premium based on earnings alone.

On the P/E multiple, BankUnited stock currently looks roughly fairly valued compared with both its tailored fair ratio and sector benchmarks.

The Bottom Line

For BankUnited, the intrinsic value estimate points to undervaluation, while the P/E view says the stock is priced close to peers. That mix hints at a stock where the market may not be fully reflecting the earnings power implied by the Excess Returns work, yet is comfortable with the current earnings multiple. The crux is whether BankUnited can keep generating returns on equity in line with those intrinsic value assumptions despite any changes in credit quality or funding costs. That single question likely decides whether today’s apparent discount is an opportunity or a value trap.
