S&T Bancorp stock has almost doubled investor capital over the past five years, yet current valuation checks send mixed signals. The intrinsic value estimate from the Excess Returns model points to meaningful upside relative to the share price, while earnings based multiples suggest the stock is already pricing in a premium.

• S&T Bancorp has delivered a 99.6% total return over five years, which puts the current share price in the spotlight for anyone considering fresh capital.
• Expectations for steady profitability and balance sheet resilience can support the intrinsic value case, although any setback in credit quality or funding costs may weigh on what investors are willing to pay.
• The company scores 3 out of 6 on our broader valuation checks, which is a mixed picture rather than a clear bargain or clear overvaluation, with the scorecard available at 3 out of 6.

The issue now is whether S&T Bancorp's current price already reflects that five year run or still leaves a margin between market price and intrinsic value.

Is S&T Bancorp a Bargain on Excess Returns?

The Excess Returns model evaluates how much profit S&T Bancorp generates above the return required by shareholders. For this stock, the model uses a book value of $39.81 per share and an average return on equity of 9.80%, which corresponds to a stable earnings power of $4.13 per share. After applying a cost of equity of $3.05 per share, the residual profit comes to an excess return of $1.08 per share.

Those excess returns are assumed to persist on a slightly higher stable book value base of $42.16 per share, which supports an estimated intrinsic value of $72.76 per share. Compared with the current share price, this indicates the stock is trading at a 30.1% discount, so S&T Bancorp appears undervalued on this model.

On the Excess Returns view, S&T Bancorp stock appears undervalued relative to the cash returns it is projected to earn on its equity base.

Has S&T Bancorp Run Too Far on Earnings?

The P/E ratio is a useful way to compare S&T Bancorp with other profitable banks. Right now the stock trades on about 12.8x earnings, which sits slightly above the Banks industry average of roughly 12.1x. It is far below the peer group average of about 30.9x, so the market is not pricing S&T Bancorp at the same level as some higher rated banking stocks.

The tailored fair P/E ratio for S&T Bancorp is 10.8x, which is lower than the current 12.8x. That gap suggests investors are paying more than this model implies for the company’s earnings, even though the headline multiple does not look stretched against many peers. On this P/E view, the stock leans toward a richer valuation rather than a clear discount.

On the P/E multiple, S&T Bancorp stock currently screens as overvalued relative to the earnings level implied by its fair ratio.

The Bottom Line

S&T Bancorp screens as undervalued on the Excess Returns intrinsic value estimate, yet overvalued on the tailored P/E multiple, so the verdict is mixed rather than clearly cheap or clearly expensive. The split reflects different anchors. Intrinsic value is tied to the earnings power of the balance sheet, while the multiple is shaped by how much growth and quality investors are currently willing to pay for compared with peers. With broader checks also mixed, the key question from here is whether S&T Bancorp can sustain the profitability and credit quality implied by the intrinsic value view without investors demanding a lower earnings multiple.
