CNB FINANCIAL CORPORATION REPORTS FIRST QUARTER EARNINGS FOR 2017,

HIGHLIGHTED BY STRONG ORGANIC LOAN GROWTH

Clearfield, Pennsylvania – April 17, 2017

CNB Financial Corporation (“CNB”) (NASDAQ: CCNE), the parent company of CNB Bank, today announced its earnings for the first quarter of 2017. Highlights include the following:

On February 15, 2017, CNB announced that it successfully completed an at-the-market common stock issuance. A total of 834,896 shares of CNB’s common stock were sold at a weighted average price of approximately $23.96, representing gross proceeds to CNB of approximately $20.0 million. Net proceeds from the transaction, after the sales commission and other expenses, were approximately $19.3 million, which will be used for general corporate purposes, including loan growth, additional liquidity, and working capital.

Joseph B. Bower, Jr., President and CEO, stated, “First quarter results are in line with our expectations. We are encouraged by the strong loan pipeline across our entire footprint but especially the Buffalo market. Buffalo has given us a very warm welcome, and we couldn’t be more excited to be there and help this area grow.”

Net Interest Margin

Net interest margin on a fully tax equivalent basis was 3.67% for the quarter ended March 31, 2017, unchanged from 3.67% for the quarter ended March 31, 2016, despite the inclusion of $769 thousand in interest expense for the three months ended March 31, 2017 from CNB’s $50 million issuance of subordinated debt to help support balance sheet growth.

Asset Quality

During the quarter ended March 31, 2017, CNB recorded a provision for loan losses of $1.0 million, as compared to a provision for loan losses of $1.2 million for the quarter ended March 31, 2016. Net chargeoffs in the first quarter of 2017 were $800 thousand, compared to net chargeoffs of $1.2 million in the first quarter of 2016. CNB Bank net chargeoffs totaled $111 thousand and $364 thousand during the quarters ended March 31, 2017 and 2016, or .02% and .09%, respectively, of average CNB Bank loans. Holiday Financial Services Corporation is CNB’s consumer discount company and recorded net chargeoffs totaling $689 thousand and $831 thousand during the quarters ended March 31, 2017 and 2016, respectively.

In the first quarter of 2017, one commercial & industrial loan that was impaired at year end 2016 but still on accrual status was placed on nonaccrual status as a result of further deterioration in the financial condition of the borrower. The additional provision for loan losses recorded in the first quarter of 2017, related to this loan, was $553 thousand.

Non-Interest Income

Excluding the effects of securities transactions, non-interest income was $4.2 million for the quarter ended March 31, 2017, compared to $3.8 million for the quarter ended March 31, 2016. Net realized gains on available-for-sale securities were $1.4 million during the quarter ended March 31, 2017 and resulted from the sale of two structured pooled trust preferred securities with a total book value of $800 thousand. Other-than-temporary impairment charges had been recorded for these securities in prior years totaling $3.2 million. Net realized and unrealized gains on trading securities were $188 thousand during the quarter ended March 31, 2017, compared to net realized and unrealized losses of $34 thousand during the quarter ended March 31, 2016. As a result of CNB’s continued focus on growing its Private Client Solutions division, wealth and asset management revenues increased 20.5% from $723 thousand in the first quarter of 2016 to $871 thousand in the first quarter of 2017.

Non-Interest Expenses

Total non-interest expenses were $17.0 million and $14.8 million during the quarters ended March 31, 2017 and 2016, respectively. Included in non-interest expenses in the first quarter of 2016 were $109 thousand of non-recurring items, with merger related expenses of $42 thousand and costs associated with our core processing system upgrade of $67 thousand.

Salaries and benefits expense increased $1.5 million, or 20.2%, during the quarter ended March 31, 2017 compared to the quarter ended March 31, 2016. As of March 31, 2017, CNB had 487 full-time equivalent staff, compared to 441 full-time equivalent staff as of March 31, 2016. The staff added during this period included both customer-facing personnel such as business development and wealth management officers, as well as support department personnel. In addition, CNB retained 20 employees in connection with its acquisition of Lake National Bank in the third quarter of 2016. Occupancy expenses increased $701 thousand, or 38.1%, during the quarter ended March 31, 2017 compared to the quarter ended March 31, 2016. Holiday Financial Services Corporation incurred non-recurring occupancy expenses totaling $141 thousand in the first quarter of 2017 as a result of the closure of two of its offices. The remainder of the increase in occupancy expenses is attributable to the two locations acquired from Lake National Bank in Mentor, Ohio, as well as locations in Worthington, Ohio; Ashtabula, Ohio; Blair County, Pennsylvania; and Buffalo, New York that have been opened since the end of the first quarter of 2016.

The ratio of non-interest expenses to average assets was 2.63% and 2.58% during the quarters ended March 31, 2017 and 2016, respectively.
