FOR IMMEDIATE RELEASE            

S&T Bancorp, Inc. Announces Second Quarter 2017 Results

-S&T Reports Solid EPS Growth-

Indiana, Pa. - July 20, 2017 - S&T Bancorp, Inc. (S&T) (NASDAQ: STBA), the holding company for S&T Bank with locations in Pennsylvania, Ohio and New York, announced today its second quarter 2017 earnings. Second quarter net income was $22.8 million, or $0.65 diluted earnings per share (EPS), compared to first quarter of 2017 net income of $18.2 million, or $0.52 diluted EPS, and second quarter of 2016 net income of $17.1 million, or $0.49 diluted EPS.

Second Quarter of 2017 Highlights:

• Excluding securities gains of $0.07 in the second quarter and $0.01 in the first quarter of 2017, EPS grew 14% compared to the first quarter of 2017 and 18% compared to the second quarter of 2016 (Non-GAAP).

• Net interest margin (FTE) (Non-GAAP) improved 7 basis points to 3.57% and net interest income increased $2.7 million, or 5.0%, to $56.6 million compared to the first quarter of 2017.

• Return on average assets was 1.29% and return on average equity was 10.55% compared to 1.06% and 8.68% for the first quarter of 2017.

• Expenses were well controlled during the quarter with an efficiency ratio of 51.48% (Non-GAAP).

• Nonperforming loans decreased $9.3 million, or 20%, compared to the first quarter of 2017.

• S&T declared a $0.20 per share dividend versus $0.19 in the same period a year ago, an increase of 5.3%.

“We are extremely pleased with our second quarter results,” said Todd Brice, president and chief executive officer of S&T.“ Net interest income growth drove solid core operating performance during the quarter. Our net interest income is 14% higher than it was in the second quarter of last year due to strong loan growth and the benefit of rising short term rates."

Net Interest Income

Net interest income increased $2.7 million, or 5.0%, to $56.6 million for the second quarter of 2017 compared to $53.9 million in the first quarter of 2017. Net interest margin on a fully taxable equivalent basis (FTE) (Non-GAAP) increased 7 basis points to 3.57% compared to 3.50% in the first quarter of 2017. The increases in net interest income and net interest margin (FTE) (Non-GAAP) were driven by average portfolio loan growth of $125 million, or 8.9% annualized, and the increase in short term rates. Loan yields increased 12 basis points to 4.30% compared to 4.18% in the first quarter, while the cost of total interest-bearing liabilities increased 8 basis points to 0.69% compared to 0.61%.

Asset Quality

Nonperforming loans showed notable improvement with a $9.3 million, or 20%, decline compared to the first quarter of 2017. Two impaired loan relationships were positively resolved resulting in a decrease of $2.2 million in specific reserves during the second quarter of 2017. Net loan charge-offs were $5.3 million compared to $2.1 million in the first quarter of 2017. The provision for loan loss was $4.9 million compared to $5.2 million in the first quarter of 2017. The allowance for loan losses to total loans was 0.96% at June 30, 2017 compared to 0.97% at March 31, 2017.

Noninterest Income and Expense

Noninterest income increased $3.3 million to $16.3 million for the second quarter of 2017 compared to $13.0 million for the first quarter of 2017. The increase primarily related to higher securities gains of $3.2 million with $3.6 million in the second quarter compared to $0.4 million in the first quarter. Noninterest expense was well controlled with a decrease of $0.2 million to $36.6 million compared to $36.8 million for the first quarter of 2017. The efficiency ratio (Non-GAAP) improved to 51.48% compared to 53.83% in the first quarter and 54.37% in the second quarter of 2016 due to expense control and higher net interest income.

Financial Condition

Total assets were unchanged at $7.1 billion as of June 30, 2017 and March 31, 2017. Total portfolio loans remained relatively unchanged compared to March 31, 2017. Total deposits remained stable with a slight decrease mainly due to a decline in brokered deposits. Risk-based capital ratios increased this quarter due to earnings retention and a reduction in risk weighted assets. All capital ratios remain above the well-capitalized thresholds of federal bank regulatory agencies.

Dividend

The Board of Directors of S&T declared a $0.20 per share cash dividend at its regular meeting held July 17, 2017. This is an increase of 5.3% compared to a common stock dividend of $0.19 per share declared in the same period in the prior year. The dividend is payable August 17, 2017 to shareholders of record on August 3, 2017.

Forward-looking statements generally relate to our financial condition, results of operations, plans, objectives, outlook for earnings, revenues, expenses, capital and liquidity levels and ratios, asset levels, asset quality, financial position, and other matters regarding or affecting S&T and its future business and operations. Forward looking statements are typically identified by words or phrases such as “will likely result,” “expect”, “anticipate,” “estimate,” “forecast,” “project,” “intend”, “ believe”, “assume”, “strategy”, “trend”,

“plan”, “outlook”, “outcome”, “continue”, “remain”, “potential,” “opportunity”, “believe”, “comfortable”, “current”, “position”, “maintain”, “sustain”, “seek”, “achieve” and variations of such words and similar expressions, or future or conditional verbs such as will, would, should, could or may. Although we believe the assumptions upon which these forward-looking statements are based are reasonable, any of these assumptions could prove to be inaccurate and the forward-looking statements based on these assumptions could be incorrect. The matters discussed in these forward-looking statements are subject to various risks, uncertainties and other factors that could cause actual results and trends to differ materially from those made, projected, or implied in or by the forward-looking statements depending on a variety of uncertainties or other factors including, but not limited to: credit losses, cyber-security concerns; rapid technological developments and changes; sensitivity to the interest rate environment including a prolonged period of low interest rates, a rapid increase in interest rates or a change in the shape of the yield curve; a change in spreads on interest-earning assets and interest-bearing liabilities; regulatory supervision and oversight; legislation affecting the financial services industry as a whole, and S&T, in particular; the outcome of pending and future litigation and governmental proceedings; increasing price and product/service competition; the ability to continue to introduce competitive new products and services on a timely, cost-effective basis; managing our internal growth and acquisitions; the possibility that the anticipated benefits from acquisitions cannot be fully realized in a timely manner or at all, or that integrating the acquired operations will be more difficult, disruptive or costly than anticipated; containing costs and expenses; reliance on significant customer relationships; general economic or business conditions; deterioration of the housing market and reduced demand for mortgages; deterioration in the overall macroeconomic conditions or the state of the banking industry that could warrant further analysis of the carrying value of goodwill and could result in an adjustment to its carrying value resulting in a non-cash charge to net income; re-emergence of turbulence in significant portions of the global financial and real estate markets that could impact our performance, both directly, by affecting our revenues and the value of our assets and liabilities, and indirectly, by affecting the economy generally and access to capital in the amounts, at the times and on the terms required to support our future businesses. Many of these factors, as well as other factors, are described in our filings with the SEC. Forward-looking statements are based on beliefs and assumptions using information available at the time the statements are made. We caution you not to unduly rely on forward-looking statements because the assumptions, beliefs, expectations and projections about future events may, and often do, differ materially from actual results.
