  • Annual revenue growth of 3.3% over the last five years was below our standards for the banking sector
  • On the bright side, its additional sales over the last five years increased its profitability as the 33.4% annual growth in its earnings per share outpaced its revenue
S&T Bancorp falls short of our expectations. There are superior opportunities elsewhere.

Why There Are Better Opportunities Than S&T Bancorp

S&T Bancorp is trading at $40.43 per share, or 1x forward P/B. S&T Bancorp’s multiple may seem like a great deal among banking peers, but we think there are valid reasons why it’s this cheap.

Cheap stocks can look like a great deal at first glance, but they can be value traps. They often have less earnings power, meaning there is more reliance on a re-rating to generate good returns - an unlikely scenario for low-quality companies.

Company Overview

Tracing its roots back to 1902 in western Pennsylvania's industrial heartland, S&T Bancorp (NASDAQ:STBA) is a Pennsylvania-based bank holding company that provides retail and commercial banking services, cash management, trust services, and investment advisory solutions.

S&T Bancorp operates primarily through its main subsidiary, S&T Bank, offering a comprehensive range of financial services to individuals and businesses. The bank's commercial lending portfolio includes real estate, industrial, and construction loans, while its consumer offerings span mortgage products and personal loans. Customers can access traditional banking services through branch locations as well as digital banking platforms.

For businesses, S&T provides cash management solutions that help companies optimize their working capital and streamline payment processes. A manufacturing company in Pennsylvania, for instance, might use S&T's treasury management services to automate accounts payable and receivable while accessing commercial loans to finance equipment purchases or expansion projects.

Beyond traditional banking, S&T generates revenue through its wealth management arm, Stewart Capital Advisors, which manages investment portfolios for individuals and institutions. The company also offers insurance products through S&T Insurance Group and title insurance services through its partial ownership of S&T Settlement Services.

S&T's business model follows the traditional banking revenue structure—earning interest income from loans while paying interest on deposits, with the difference (net interest margin) forming a significant portion of earnings. Additional revenue comes from fees for services like wealth management, insurance products, and transaction processing.

As a regulated financial institution, S&T operates under the supervision of the Federal Reserve, the FDIC, and the Pennsylvania Department of Banking and Securities, with deposits insured by the FDIC up to applicable limits.

4. Regional Banks

Regional banks, financial institutions operating within specific geographic areas, serve as intermediaries between local depositors and borrowers. They benefit from rising interest rates that improve net interest margins (the difference between loan yields and deposit costs), digital transformation reducing operational expenses, and local economic growth driving loan demand. However, these banks face headwinds from fintech competition, deposit outflows to higher-yielding alternatives, credit deterioration (increasing loan defaults) during economic slowdowns, and regulatory compliance costs. Recent concerns about regional bank stability following high-profile failures and significant commercial real estate exposure present additional challenges.

S&T Bancorp competes with other regional banks operating in Pennsylvania and Ohio, including PNC Financial Services (NYSE:PNC), F.N.B. Corporation (NYSE:FNB), Northwest Bancshares (NASDAQ:NWBI), and First Commonwealth Financial (NYSE:FCF).

5. Sales Growth

Two primary revenue streams drive bank earnings. While net interest income, which is earned by charging higher rates on loans than paid on deposits, forms the foundation, fee-based services across banking, credit, wealth management, and trading operations provide additional income. Unfortunately, S&T Bancorp’s 3.3% annualized revenue growth over the last five years was mediocre. This was below our standard for the banking sector and is a tough starting point for our analysis.

S&T Bancorp Quarterly Revenue

Long-term growth is the most important, but within financials, a half-decade historical view may miss recent interest rate changes and market returns. S&T Bancorp’s performance shows it grew in the past but relinquished its gains over the last two years, as its revenue fell by 2.2% annually. S&T Bancorp Year-On-Year Revenue GrowthNote: Quarters not shown were determined to be outliers, impacted by outsized investment gains/losses that are not indicative of the recurring fundamentals of the business.

This quarter, S&T Bancorp grew its revenue by 6.9% year on year, and its $103 million of revenue was in line with Wall Street’s estimates.

Net interest income made up 84.9% of the company’s total revenue during the last five years, meaning S&T Bancorp barely relies on non-interest income to drive its overall growth.

S&T Bancorp Quarterly Net Interest Income as % of Revenue

Our experience and research show the market cares primarily about a bank’s net interest income growth as non-interest income is considered a lower-quality and non-recurring revenue source.

6. Earnings Per Share

Revenue trends explain a company’s historical growth, but the long-term change in earnings per share (EPS) points to the profitability of that growth – for example, a company could inflate its sales through excessive spending on advertising and promotions.

S&T Bancorp’s EPS grew at an astounding 45.1% compounded annual growth rate over the last five years, higher than its 3.3% annualized revenue growth. However, this alone doesn’t tell us much about its business quality because its efficiency ratio didn’t improve.

S&T Bancorp Trailing 12-Month EPS (GAAP)

Like with revenue, we analyze EPS over a more recent period because it can provide insight into an emerging theme or development for the business.

For S&T Bancorp, its two-year annual EPS declines of 4.8% mark a reversal from its (seemingly) healthy five-year trend. We hope S&T Bancorp can return to earnings growth in the future.

In Q3, S&T Bancorp reported EPS of $0.91, up from $0.85 in the same quarter last year. This print beat analysts’ estimates by 6%. Over the next 12 months, Wall Street expects S&T Bancorp’s full-year EPS of $3.46 to shrink by 2.5%.

7. Tangible Book Value Per Share (TBVPS)

The balance sheet drives banking profitability since earnings flow from the spread between borrowing and lending rates. As such, valuations for these companies concentrate on capital strength and sustainable equity accumulation potential.

This is why we consider tangible book value per share (TBVPS) the most important metric to track for banks. TBVPS represents the real, liquid net worth per share of a bank, excluding intangible assets that have debatable value upon liquidation. Other (and more commonly known) per-share metrics like EPS can sometimes be murky due to M&A or accounting rules allowing for loan losses to be spread out.

S&T Bancorp’s TBVPS grew at an excellent 8.2% annual clip over the last five years. TBVPS growth has also accelerated recently, growing by 13.9% annually over the last two years from $22.11 to $28.69 per share.

Over the next 12 months, Consensus estimates call for S&T Bancorp’s TBVPS to grow by 6.7% to $30.61, mediocre growth rate.

8. Balance Sheet Assessment

Leverage is core to a financial firm’s business model (loans funded by deposits). To ensure economic stability and avoid a repeat of the 2008 GFC, regulators require certain levels of capital and liquidity, focusing on the Tier 1 capital ratio.

Tier 1 capital is the highest-quality capital that a firm holds, consisting primarily of common stock and retained earnings, but also physical gold. It serves as the primary cushion against losses and is the first line of defense in times of financial distress.

This capital is divided by risk-weighted assets to derive the Tier 1 capital ratio. Risk-weighted means that cash and US treasury securities are assigned little risk while unsecured consumer loans and equity investments get much higher risk weights, for example.

New regulation after the 2008 financial crisis requires that all firms must maintain a Tier 1 capital ratio greater than 4.5%. On top of this, there are additional buffers based on scale, risk profile, and other regulatory classifications, so that at the end of the day, firms generally must maintain a 7-10% ratio at minimum.

Over the last two years, S&T Bancorp has averaged a Tier 1 capital ratio of 14.2%, which is considered safe and well capitalized in the event that macro or market conditions suddenly deteriorate.

9. Return on Equity

Return on equity, or ROE, quantifies bank profitability relative to shareholder equity - an essential capital source for these institutions. Over extended periods, superior ROE performance drives faster shareholder wealth compounding through reinvestment, share repurchases, and dividend growth.

Over the last five years, S&T Bancorp has averaged an ROE of 10.3%, healthy for a company operating in a sector where the average shakes out around 7.5% and those putting up 15%+ are greatly admired. This is a bright spot for S&T Bancorp.

11. Is Now The Time To Buy S&T Bancorp?

Updated: December 3, 2025 at 11:21 PM EST

Before making an investment decision, investors should account for S&T Bancorp’s business fundamentals and valuation in addition to what happened in the latest quarter.

S&T Bancorp isn’t a terrible business, but it doesn’t pass our bar. For starters, its revenue growth was weak over the last five years. And while its astounding EPS growth over the last five years shows its profits are trickling down to shareholders, the downside is its declining net interest margin shows its loan book is becoming less profitable. On top of that, its net interest income growth was weak over the last five years.

S&T Bancorp’s P/B ratio based on the next 12 months is 1x. This valuation multiple is fair, but we don’t have much faith in the company. We're fairly confident there are better investments elsewhere.

Wall Street analysts have a consensus one-year price target of $40.40 on the company (compared to the current share price of $40.43).
