Another View on S&T Bancorp’s Valuation

The earlier fair value story for S&T Bancorp leaned on earnings forecasts and a target P/E around 13x. The market today values the stock at a P/E of 12.7x compared with a fair ratio of 10.4x and a US Banks industry average of 12x. That means investors are paying a premium to the fair ratio, while only slightly above the sector, which can limit upside if sentiment cools or earnings disappoint.

The question for you is whether that extra P/E premium feels like a reasonable price for S&T Bancorp’s track record and balance sheet, or a margin of safety that has already been used up.
