CANFIELD, Ohio (April 25, 2012) – Farmers National Banc Corp. (Farmers) (NASDAQ: FMNB) today reported financial results for the three months ended March 31, 2012.

Net income for the three months ended March 31, 2012 was $2.5 million, compared to $1.7 million for the same three month period in 2011. On a per share basis, net income for the first quarter ended March 31, 2012 was $0.13 per diluted share, compared to $0.10 for the first quarter ended March 31, 2011 and $0.16 for the fourth quarter ended December 31, 2011. The tangible common equity ratio increased to 9.91% at March 31, 2012, compared to 9.56% at March 31, 2011, mainly as a result of net income. Farmers’ total assets reported at March 31, 2012 were $1.1 billion, representing a 9.1% increase compared to $1.0 billion in total assets recorded at March 31, 2011.

John S. Gulas, President and CEO, stated “Our net income increased to $2.5 million for the three months ended March 31, 2012, which represents a 49% increase over the $1.7 million reported for the same period in 2011. Noninterest income increased 4% during the same three month period. This increase reflects the continued benefit from our strategy to diversify income streams. The provision for loan losses decreased from $1.9 million for the three month period ending March 31, 2011 to $0 for the three months ended March 31, 2012. This decrease is a result of improved credit quality, as net charge-offs have declined from $1.0 million for three months ended March 31, 2011 to $374 thousand for the same period in 2012. We have also seen a decline in our 30-89 day delinquencies, from $3.4 million at March 31, 2011 to $2.9 million at March 31, 2012. Even with the reduction in our provision, because of improved credit quality, we continue to maintain strong reserves against probable incurred losses.”

Net loans increased $5.2 million (or 1%) in comparing the first quarter of 2012 to the fourth quarter of 2011. Most of the loan growth in the past three months has occurred in the commercial real estate portfolio. Net loans were reported at $567.2 million at March 31, 2012, which compares to $566.3 million at the same time in 2011. Farmers believes its demand experience for business and consumer credit is consistent with the experience of other banks in the Federal Reserve’s Fourth District and banks nationally per the Federal Reserve Beige Book. Deposits increased $121.3 million, or 15.9%, from $765.3 million at March 31, 2011 to $886.6 million at March 31, 2012, as customers continue to seek the safety and security of FDIC insured deposit accounts.

Stockholders’ equity totaled $115.4 million, or 10.4% of total assets, at March 31, 2012, an increase of $12.3 million, or 11.9%, compared to $103.1 million at March 31, 2011. The increase is also the result of net income and mark to market adjustments in investment securities, offset by cash dividends paid to shareholders during the past twelve months. Shareholders received a special one-time $0.03 cash dividend on February 28, 2012, a regular $0.03 per share cash dividend on March 31, 2012 and a total of $0.15 per share cash dividends paid in the past four quarters. Book value per share increased 11.2% from $5.52 per share at March 31, 2011 to $6.14 per share at March 31, 2012. Farmers’ tangible book value per share also increased 12.6% from $5.16 per share at March 31, 2011 to $5.81 per share at March 31, 2012.

Net Interest Income — Net interest income was $9.2 million for the first quarter of 2012, which compared to $9.1 million in the first quarter of 2011. The net interest margin to average earning assets on a fully taxable equivalent basis decreased 32 basis points to 3.90% for the three months ended March 31, 2012, compared to 4.22% for the same period in the prior year. The decrease in net interest margin is largely a result of the change in the mix of interest earning assets. Loans, which yield more than securities, comprised a smaller level of interest-earning assets in the current year. At March 31, 2012, loans were 56% of average earning assets, compared to 62% at March 31, 2011. In comparing the quarters ending March 31, 2012 and 2011, yields on earning assets decreased 54 basis points, while the cost of interest bearing liabilities decreased 24 basis points.

Noninterest Income — Noninterest income was $2.7 million for the first quarter of 2012, increasing 4.2% from $2.6 million compared to the same quarter of 2011. Trust fees were $1.4 million for the quarter ended March 31, 2012, an increase of $80 thousand, or 6%, compared to the same quarter in 2011. Income from the sale of residential real estate loans also increased from none in first quarter of 2011 to $65 thousand in the first quarter of 2012 as the company continues to develop its’ secondary mortgage operations.

Noninterest Expense — Noninterest expense totaled $8.6 million for the first quarter of 2012, which is $825 thousand more than the $7.8 million in the same quarter in 2011. Most of this increase is a result of a $541 thousand or 12.9% increase salaries and employee benefits, due to a higher number of employees in the current quarter. The higher employee count is attributed primarily to our North Canton and Secondary Mortgage project expansions. Employee health insurance costs also increased $142 thousand as a result of a higher level of claims. Advertising expense is also $103 thousand higher in the first quarter of 2012 compared to the same quarter in 2011. This increase is primarily a result of a higher level of production costs related to television advertisements in the current year.

Farmers’ tax equivalent efficiency ratio for the three month period ended March 31, 2012 was 68.4% compared to 62.6% for the same period in 2011. The decline in the efficiency ratio was the result of the $825 thousand increase in noninterest expenses as explained in the previous paragraph.

Asset Quality — Non-performing loans equaled 1.91% of total loans at March 31, 2012, unchanged from March 31, 2011. Loans 30–89 days delinquent decreased $502 thousand, or 14.8%, to $2.9 million since March 31, 2011. Non-performing loans totaled $11.0 million at March 31, 2012, unchanged compared to December 31, 2011 and March 31, 2011, respectively. On March 31, 2012, the ratio of the allowance for loan losses (ALLL) to non-performing loans was 86%, compared to 92% at March 31, 2011. At March 31, 2012, the ALLL/total loan ratio was 1.64%, compared to 1.76% at March 31, 2011. For the three months ended March 31, 2012, management did not record a provision to the allowance for loan losses, compared to no provision in the preceding quarter and a $1.9 million provision in the same three month period in the prior year. Although non-performing loans remained consistent from the previous quarter, other factors lead to not recording a provision in the first quarter. The primary factor was the lower historical loss percentage applied to homogeneous and pass rated loans due to recent lower levels of net charge-offs. During the most recent period end, management computed the historical loss percentage based upon the loss history of the past 12 quarters. In previous periods, management used a historical loss percentage based on the past 8 quarters. The Company believes that using a loss history of the previous 12 quarters will capture more cyclicality in the loan portfolio. It should also be noted that net charge-offs for the quarter ending March 31, 2012 decreased to $374 thousand, compared to $1.2 million and $1.0 million for the fourth quarter of 2011 and the first quarter of 2011, respectively.
