2014 THIRD QUARTER FINANCIAL RESULTS

CANFIELD, Ohio (October 22, 2014) – Farmers National Banc Corp. (Farmers) (NASDAQ: FMNB) today reported financial results for the three and nine months ended September 30, 2014.

Net income for the three months ended September 30, 2014 was $2.3 million, or $0.12 per diluted share, which compares favorably to $1.6 million, or $0.09 per diluted share for the third quarter ended September 30, 2013. Net income for the nine months ended September 30, 2014 was $6.8 million, a 24.3% increase compared to $5.5 million for the same period in 2013. On a per share basis, net income for the nine months ended September 30, 2014 was $0.36, an increase of 24.1% compared to the nine month period ended September 30, 2013. Last year’s results included $1.3 million in severance expenses related to terminated employees.

Kevin J. Helmick, President and CEO, stated, “Our improvement in net income for the nine months ended September 30, 2014 and the third quarter of 2014 is a result of our continued focus on increasing noninterest income and control of noninterest expenses. The continued focus on increasing fee-based revenues and reducing expenses has also contributed to an improvement in our efficiency ratio to 69.9% from 77.2% during the first nine months of 2014 compared to the same period in 2013. It is important to note that noninterest income excluding security gains has increased 8.4% in comparing the third quarter of 2014 to the third quarter of 2013. We are also pleased to report that loans increased 5.8% in the past twelve months.”

2014 Third Quarter Financial Highlights

Total loans were $647 million at September 30, 2014, compared to $611.3 million at September 30, 2013. This represents an increase of 5.8%. The increase in loans is a direct result of Farmers’ focus on loan growth utilizing a talented lending and credit team while adhering to a sound underwriting discipline. Most of the increase in loans has occurred in the commercial real estate, commercial and industrial and residential real estate loan portfolios. Loans comprised 59.0% of the Bank’s average earning assets in 2014, an improvement compared to 55.7% in 2013.

Non-performing assets to total assets remain at a safe level, currently at 0.67%. Early stage delinquencies also continue to remain at low levels, at $4.9 million or 0.76% of total loans at September 30, 2014.

The net interest margin for the quarter ended September 30, 2014 was 3.58%, an increase of 4 basis points from 3.54% reported for the quarter ended June 30, 2014. Asset yields increased 2 basis points, while the cost of interest-bearing liabilities decreased 2 basis points.

Noninterest income was $3.9 million for the third quarter of 2014, an 8.4% improvement compared to the same quarter in 2013, after excluding security gains of $1 thousand in current quarter and $597 thousand in the prior year’s quarter. Trust fees increased $193 thousand or 14.1%, service charges on deposit accounts also increased $78 thousand or 12.3% and retirement plan consulting fees increased $551 thousand or 269.8%. Investment commissions also increased $205 thousand or 118.5%.

The Company underwent a cost reduction program in 2013 that included the closure of two retail branch locations and the elimination of several full time positions. During the first nine months of 2014, the company has remained committed to managing the level of noninterest expenses. As a result of these actions, the Company’s noninterest expenses were $9.8 million for the quarter ended September 30, 2014, compared to the $10.9 million reported in the third quarter in 2013. Excluding severance expenses of $1.3 million for terminated employees recorded in the quarter ended September 30, 2013, noninterest expenses would have been $9.6 million.

On July 29, the Company announced an odd lot share buyback program with the goal of reducing servicing and administrative costs associated with shareholders who own 99 or fewer shares. This program resulted in 6,568 shares purchased for $50 thousand. In addition to the odd lot buyback program, the Company repurchased 221,500 shares in the open market at a cost of $1.7 million. Both of these programs reduced total common shares outstanding by 1.2% from June 30, 2014. The tangible common equity ratio improved to 9.88% at September 30, 2014 compared to 8.96% one year ago.

2014 Outlook

Mr. Helmick added: “We continue to experience increases in noninterest income and growth in our loan portfolio which has resulted in higher total revenue. We look forward to the ensuing quarters as the economic outlook improves. We also continue our discipline of closely monitoring levels of non-interest expense while growing non-interest revenues.”
