Here are 3-5 expected drivers of future revenue growth for S&T Bancorp (STBA) over the next 2-3 years:

1. Loan Growth, particularly in Commercial, Small Business, and Consumer Segments: S&T Bancorp has indicated a focus on and expectation of continued loan growth. In the fourth quarter of 2023, growth was particularly focused on commercial and small business lending. More recently, in Q3 2025, the company observed overall consumer loan growth consistent with expectations at approximately 6% annualized, and commercial pipelines reached their highest point in five quarters, leading to guidance for mid-single-digit loan growth in Q4. Analysts also emphasize continued loan growth in key geographies as a near-term catalyst. The company is targeting mid-single-digit loan growth for 2025.
2. Net Interest Margin (NIM) Management and Expansion: Proactive management of its balance sheet to optimize net interest margin is a key driver. While some periods have seen NIM contraction, the company has also demonstrated NIM expansion. The Q1 2025 earnings call highlighted a 4 basis point NIM expansion due to decreased funding costs and a balance sheet positioned for neutrality, with expectations to maintain a relatively stable margin even in an environment of aggressive rate cuts. In Q3 2025, NIM expanded to 3.93%, increasing by 5 basis points from the prior quarter, which, combined with loan growth, contributed to quarterly revenue growth.
3. Consistent Customer Deposit Growth: Sustained growth in customer deposits contributes to a stable funding base and supports lending activities. S&T Bancorp reported customer deposit growth of just under $100 million, or 5.5% annualized, in Q4 2023. This trend continued into Q1 2025 with over 7% annualized customer deposit growth, marking the seventh consecutive quarter of such growth. Consistent deposit growth is viewed by analysts as a key factor for long-term stability.
4. Strategic Investments in Technology and Regional Expansion: S&T Bancorp's ongoing investments in technology and regional expansion are expected to bolster its growth ambitions. These initiatives are aimed at reinforcing the company's deposit franchise and generating future revenue opportunities.
5. Growth in Non-Interest Income (Fee Income): While net interest income forms the majority of the company's revenue, the generation of non-interest income from various fee-based services also contributes to overall revenue growth. The company anticipates a quarterly run rate for non-interest income (fees) to be approximately $13 million to $14 million. Specific areas like wealth management contribute to this segment.
