FOR IMMEDIATE RELEASE

S&T Bancorp, Inc. Announces Third Quarter 2015 Results and Declares Increased Quarterly Dividend

Indiana, Pa. -October 20, 2015 - S&T Bancorp, Inc. (S&T) (NASDAQ: STBA), the holding company for S&T Bank with branch locations in 16 southwestern and southcentral Pennsylvania counties, and loan production offices in northeast and central Ohio, and western New York, announced today its third quarter of 2015 earnings. Third quarter earnings were $18.6 million, or $0.54 per diluted share, compared to second quarter of 2015 earnings of $18.2 million, or $0.52 per diluted share, and third quarter of 2014 earnings of $14.7 million, or $0.49 per diluted share.

Highlights:

• Diluted earnings per share increased 10.2% for the third quarter of 2015 compared to the third quarter of 2014.

• Return on average assets was 1.20% and return on average equity was 9.51% for the third quarter of 2015.

• Portfolio loans increased $128 million from June 30, 2015, representing a 10.6% annualized rate.

• Net loan charge-offs to average loans remained low at 0.17% annualized for the third quarter of 2015.

• S&T’s Board of Directors approved a 5.6% increase in the quarterly cash dividend to $0.19 per share.

“We are pleased to announce another quarter with solid profitability metrics,” said Todd Brice, president and chief executive officer of S&T. “Our continued excellent performance is driven by the efforts of our team at every level of the organization. This has resulted in strong consumer and commercial loan growth and improved efficiency across all lines of business.”

Net Interest Income

Net interest income increased $0.8 million to $49.6 million compared to $48.8 million for the second quarter of 2015. The increase in net interest income was primarily due to an increase in average loans and one additional day in the third quarter compared to the second quarter. Average loans increased

$105 million for the third quarter compared to the second quarter of 2015 due to strong organic loan growth. Net interest income and net interest margin on a fully taxable equivalent basis (FTE) were impacted by $2.2 million of accretion from purchase accounting adjustments during the third quarter compared to $2.7 million in the second quarter. Net interest margin (FTE) decreased 6 basis points to 3.61% compared to 3.67% for the second quarter of 2015, primarily due to the decrease in accretion of the purchase accounting adjustments and lower rates and fees on loans.

Asset Quality

Total nonperforming assets increased $4.4 million to $24.3 million, or 0.49% of total loans plus OREO, at September 30, 2015 from $19.9 million, or 0.41% of total loans plus OREO, at June 30, 2015. Net charge-offs for the third quarter of 2015 increased $0.8 million to $2.1 million compared to net charge-offs of $1.3 million in the second quarter of 2015. The provision for loan losses was $3.2 million for the third quarter of 2015 compared to $2.1 million for the second quarter of 2015. The allowance for loan losses for originated loans was $49.9 million, or 1.20% of total originated loans, compared to $48.8 million, or 1.23% of total originated loans, at June 30, 2015.

Noninterest Income and Expense

Noninterest income decreased $0.9 million to $12.5 million compared to $13.4 million for the second quarter of 2015. The decrease in noninterest income was primarily due to a decrease in other income related to lower letter of credit and commercial loan swap fees compared to the second quarter of 2015. Noninterest expense decreased $1.6 million to $33.8 million compared to $35.4 million in the second quarter of 2015. The decrease was mainly due to $0.9 million of merger related expense in the second quarter of 2015, lower salaries and employee benefits expense related to a reduction in incentive expense and payroll taxes, lower marketing expense and lower shares tax compared to the second quarter of 2015.

Financial Condition

Total assets increased $81.6 million to $6.2 billion at September 30, 2015 compared to $6.1 billion at June 30, 2015. Loan growth was strong for the quarter with an increase in total portfolio loans of $128 million, or a 10.6% annualized rate. Commercial loans increased $94.5 million during the quarter, or a 10.3% annualized rate, primarily due to growth in the commercial real estate and commercial construction portfolios. Consumer loans increased $32.9 million, or an 11.3% annualized rate, primarily due to growth in residential mortgages and home equity loans. Total deposits remained unchanged at $4.9 billion at both September 30, 2015 and June 30, 2015. S&T’s capital ratios increased this quarter as earnings retention outpaced asset growth. All capital ratios remain above the well-capitalized thresholds of federal bank regulatory agencies.

Dividend

The Board of Directors of S&T declared a $0.19 per share cash dividend at its regular meeting held October 19, 2015, representing a 5.6% increase over the prior quarter cash dividend. The dividend is payable on November 19, 2015 to shareholders of record on November 5, 2015.
