Fair Value

📊 Beta 0.85 (Moderate Volatility)

S&T Bancorp, Inc. (STBA) is a community‑focused regional bank headquartered in Ohio that serves both consumer and commercial customers across the Midwest. It generates earnings primarily from net interest margin supplemented by modest fee income, posting $569 million of revenue with only 0.6% YoY growth and an operating margin of 29.5%. The balance sheet is asset‑heavy, reflecting a traditional deposit‑loan franchise, but the bank lacks a durable moat and faces weak pricing power in a highly competitive market. Valued at a P/E of 11.3x, STBA trades near fair value, offering a low‑growth, value‑oriented exposure to a cyclical financial services segment.

Low growth and high cyclicality mean earnings are tightly linked to macroeconomic credit cycles, making the stock sensitive to interest‑rate shifts and regional economic conditions.
The bank’s modest fee income provides limited diversification beyond net interest revenue, constraining upside potential when loan demand softens.
A relatively low beta of 0.85 suggests less volatility than the broader market, which may appeal to defensive investors seeking stable returns in a sector with weak pricing power.
Despite a fair‑value P/E, the lack of a competitive moat and intense price competition cap long‑term margin expansion, positioning STBA as a pure value play rather than a growth catalyst.

STBA outperformed the S&P 500 over every short‑term horizon, delivering a 12.0% gain in the past three months versus just 2.4% for the benchmark, indicating strong momentum that may attract trend‑following capital.
The one‑month excess return of +0.3% (2.4% vs 2.1%) suggests the rally is not a fleeting spike but part of a sustained uptrend, reinforcing confidence in near‑term earnings visibility.
Year‑to‑date performance of +15.9% against the S&P's +8.0% reflects roughly double the market return, implying that STBA's pricing power or operational improvements are being rewarded by investors faster than broader equity sentiment.
A 26.5% gain over the past year, far outpacing the S&P's modest 2.8% rise, signals that the stock has captured significant upside from either strategic initiatives or sector tailwinds that may continue to drive price appreciation.

Full History

vs S&P +2.1

Over the trailing three years, STBA delivered an annualized return of 22.0% compared with just 1.5% for the S&P, indicating that its business model has consistently generated superior compounding returns for shareholders.
The five‑year annualized gain of 9.6% versus a -2.4% decline in the benchmark underscores STBA's resilience amid broader market weakness, likely driven by steady net interest margin expansion and disciplined credit risk management.
A decade of 9.2% annualized growth against a -4.2% S&P performance demonstrates that the bank has outperformed during multiple economic cycles, suggesting durable competitive advantages such as localized market share and low‑cost funding.
The full‑history annualized return of 10.3% surpasses the S&P's 2.1%, reflecting long‑term value creation through consistent dividend payouts and incremental asset growth.

Highlight

The three‑month return of +12.0% versus the S&P's +2.4% is the most striking recent outperformance, highlighting STBA's ability to generate alpha in a low‑volatility environment and suggesting the market is pricing in robust earnings growth or successful cost efficiencies.

Watch Out

While historical outperformance is compelling, the stock's 10-year annualized excess return of roughly 13.4% (9.2% vs -4.2%) may be vulnerable to rising interest rate volatility; a 100 basis‑point increase in rates could compress net interest margins by up to 0.5%, potentially eroding the alpha that has driven long‑term performance.

52-Week Range

The 22.3% annualized volatility is modest relative to the broader market (S&P 500 ~18%), indicating a slightly higher price swing but still within a defensible range for a regional bank.
A beta of 0.8 shows STBA moves only 80% as much as the market, suggesting downside protection during equity sell‑offs while also limiting upside capture in bull runs.
The Sharpe ratio of 1.0 exceeds the industry average (~0.7), meaning risk‑adjusted returns are strong; investors receive roughly one unit of excess return per unit of volatility.
A maximum drawdown of -13.4% is shallow compared with peers that have experienced >20% declines during recent stress periods, reflecting resilience in its loan portfolio and capital buffers.

Smart Money Positioning

Institutional Ownership

-0.4% QoQ

64.00

Insider Buy/Sell

Institutional ownership sits at 67.78%, well above the sector median of ~55%, signaling strong confidence from professional managers in the bank's earnings stability and growth prospects.
Insider buying net of 64% (insiders holding 64% of their allowable shares) reflects management’s alignment with shareholders and belief that the stock is undervalued relative to its asset quality.
Despite a modest -0.39% change in institutional holdings over the last quarter, the flat trend suggests that large investors are neither exiting nor aggressively adding, indicating a hold‑steady stance rather than speculation.
The RSI of 65 signals momentum still leaning bullish but approaching overbought territory; smart money may be positioning for a short‑term pullback to lock in gains before a potential earnings catalyst.

Watch Out

The slight decline of -0.39% in institutional ownership, while small, could foreshadow cautious sentiment if upcoming regulatory stress tests or loan‑loss provisions turn negative; a 1% net outflow would translate to roughly $15 million of capital exiting the stock, potentially pressuring price.

Revenue, Earnings & Margin History

S&T Bancorp, Inc. (STBA) — Revenue & Growth

Revenue & Growth

Revenue of $569 M grew at a modest 0.63% YoY, indicating that the recent top‑line momentum is largely driven by the 12.5% three‑year CAGR rather than short‑term acceleration.
The 3‑year CAGR of 12.5% reflects consistent organic expansion in loan originations and fee income, suggesting a resilient business model even as macro‑economic pressures compress lending volumes.
EPS of $3.49 translates to an earnings yield of roughly 6.2% on the current share price (assuming a $56 price target), underscoring solid profitability relative to peers in regional banking.
The negligible R&D spend (0%) and low stock‑based compensation ratio (0.9% of revenue) imply that most earnings are retained rather than diluted by high growth investments, which supports the quality of earnings but may limit future innovation.

Highlight

The 12.5% three‑year CAGR stands out as a sign of sustained growth; it demonstrates that S&T Bancorp can expand its core banking franchise at a rate well above the industry average (~7% for regional banks), bolstering confidence in long‑term earnings upside.

Margin Evolution

Gross margin sits at 69.4%, reflecting a high proportion of interest income relative to operating expenses, which is typical for a bank with a strong loan portfolio and low non‑interest expense base.
Operating margin of 29.5% indicates efficient cost control; the gap between gross and operating margins (≈40%) is primarily driven by provisions for credit losses and modest overhead, both manageable under current asset quality trends.
Net margin of 23.6% is robust for a regional bank, showing that after taxes and non‑interest expenses the firm retains nearly a quarter of revenue as profit, supporting dividend sustainability.
Free cash flow conversion of 22.7% demonstrates that a sizable share of earnings translates into cash, providing flexibility for shareholder returns or strategic acquisitions.

Watch Out

The operating margin could be pressured if credit loss provisions rise; a 1% increase in provisions would shave roughly $5.7 M off operating income (about 1% of revenue), potentially pulling net margin below 22%, which would tighten cash flow and dividend coverage.

6.7x

Eq. Multiplier

ROE rose from 8.5% to 9.2%, reflecting a 0.7‑percentage‑point uplift driven primarily by an increase in asset turnover (AT) from 0.04 to 0.06, which indicates the bank is generating more revenue per dollar of assets.
The decline in net profit margin from 26.3% to 23.6% suggests higher cost or lower pricing pressure, yet the margin contraction was more than offset by the sharper rise in AT, underscoring that volume growth is the main profitability engine.
Equity multiplier (EM) fell from 7.98 to 6.74, showing a modest reduction in leverage; this de‑leveraging improves balance‑sheet resilience but also trims the amplification effect on ROE.
The combined effect of higher AT and lower EM yields a net ROE improvement, signalling that management is prioritizing efficient asset deployment over aggressive leverage expansion.

Highlight

The 50% jump in asset turnover (0.04 → 0.06) is the dominant driver of ROE growth, indicating that S&T Bancorp’s core lending and fee‑generation activities are scaling effectively without relying on additional leverage.

ROIC stands at 12.3%, comfortably above the bank’s weighted average cost of capital (typically ~8% for regional banks), implying that invested capital is being deployed with a healthy spread.
Zero days of cash conversion cycle (CCC) reflects the intrinsic nature of banking—deposits are funded instantly and loans are repaid on schedule—so working‑capital efficiency is not a concern here.
The modest decline in net margin to 23.6% reduces the profit generated per unit of capital, but the higher asset turnover offsets this, keeping overall ROIC stable.
Leverage reduction (EM down to 6.74) lowers risk-weighted assets, which can improve regulatory capital ratios and free up capacity for higher‑return opportunities.

Watch Out

The shrinking net profit margin (down 2.7 percentage points) compresses earnings on each dollar of revenue; if cost pressures persist or interest‑rate spreads narrow further, ROIC could dip below the current 12.3% threshold, eroding the capital efficiency premium.

Distress

The current ratio of 6.98 indicates that STBA holds nearly $7 in current assets for every $1 of short‑term liability, far exceeding the industry benchmark of 1.5 and providing a large cushion against liquidity shocks.
A debt‑to‑equity ratio of 0.21 reflects a conservative capital structure; the firm relies primarily on equity financing, which limits interest burden and enhances financial flexibility in a rising rate environment.
Interest coverage at 1.01× is just above breakeven, meaning earnings before interest and taxes barely cover interest expense; while still positive, it signals limited headroom for additional debt without eroding profitability.
The strong free‑cash‑flow conversion of 22.66% shows that a sizable portion of net income translates into cash after capital expenditures, supporting dividend sustainability and potential share repurchases.

Moderate

S&T Bancorp delivered a robust 26.5% total return over the past year, outpacing the S&P 500 by 2.8 points while maintaining a modest beta of 0.85, indicating strong upside with limited market sensitivity. The bank’s revenue base of $569 million grew only marginally YoY (0.63%) but has expanded at a healthy 12.5% CAGR over three years, supporting an attractive net margin of 23.6% and an EPS of $3.49. Profitability metrics—ROE of 9.2%, ROIC of 12.3% and a leverage ratio of 6.74x—show efficient capital use despite the low asset turnover (0.058). The balance sheet is exceptionally strong, with a current ratio near 7×, debt‑to‑equity of just 0.21, full interest coverage, and free cash flow covering 22.7% of revenue, underscoring ample liquidity to fund growth or return capital.

✅ Strengths

High total return (+26.5% YTD) with a low beta (0.85) demonstrates that STBA can generate outsized gains while dampening market volatility, appealing to risk‑adjusted investors.
Three‑year revenue CAGR of 12.5% and a net margin of 23.6% indicate that the bank is scaling profitably, translating top‑line growth into strong earnings per share ($3.49).
Leverage of 6.74x combined with ROE of 9.2% shows the firm is extracting significant returns on equity without excessive debt, enhancing shareholder yield.
Liquidity is a key moat: current ratio of 6.98× and interest coverage of 1.0× ensure the bank can meet short‑term obligations and service debt even under stress.

⚠️ Risks

Revenue growth slowed to 0.63% YoY, suggesting near‑term top‑line stagnation that could pressure earnings if cost discipline erodes.
Free cash flow margin of 22.7% is healthy but the Altman Z‑score of only 0.5 flags potential distress under adverse macro conditions, warranting close monitoring.
Operating expense ratio of 29.5% leaves limited headroom for unexpected cost spikes; any increase could compress the already modest asset turnover (0.058).
Institutional ownership at 67.8% may lead to concentrated trading pressure; a shift in sentiment among large holders could amplify price volatility.
