Net Income	$	1,342,000		$	1,416,000

Millersburg, Ohio – April 21, 2015 – CSB Bancorp, Inc. (CSBB) today announced first quarter 2015 net income of $1,342,000 or $.49 per basic and diluted share, as compared to $1,416,000 or $.52 per basic and diluted share for the same period in 2014.

Annualized returns on average common equity (“ROE”) and average assets (“ROA”) for the quarter were 9.33% and 0.87%, respectively, compared with 10.70% and 0.97% for the first quarter of 2014.

Eddie Steiner, President and CEO commented, “Employment levels continue to increase across the markets we serve, and there is growing confidence among consumers and businesses that the economy will sustain its forward momentum. Home mortgage volumes are noticeably above year ago levels. Businesses are generally doing fairly well although many are remaining cautious and using accumulated cash reserves for expansion in lieu of borrowing.”

Revenue, on a fully-taxable equivalent basis, totaled $6.1 million during the quarter, a 4% increase from the prior-year first quarter. Net interest income improved by $116 thousand as compared to first quarter 2014, while other income increased $101 thousand attributable primarily to an increase in gain on sale of mortgage loans to the secondary market, gain on securities sold and an increase in debit card interchange fees.

Non-interest expense amounted to $3.9 million during the quarter, an increase of $271 thousand or 7% from first quarter 2014. The Company’s first quarter efficiency ratio amounted to 64.1% as compared to 61.6% for the same quarter in the prior year. Salary and employee benefits rose $131 thousand, or 6%, on a quarter over prior year quarter with increases in base salary, medical and employment taxes. During the first quarter in 2015 a one-time expense of $110 thousand was incurred to contract a professional firm to assist the company with the assessment of market opportunities and long-term strategic goals.

Net interest margin amounted to 3.52% for the quarter compared to 3.43% from the linked December quarter and 3.63% for the prior year’s first quarter. On a linked quarter basis, increases were recognized in first quarter 2015 asset yields as well as a 2 basis point decrease in liability costs as compared to the quarter ended December 2014. The margin decrease year over year resulted from a 16 basis point decrease in total interest yield partially offset with a 5 basis point decrease in interest rates on all liabilities. The low interest rate environment and lower than projected commercial and retail loan growth for the quarter is reflected in the lower margins year over year.

Federal income tax provision totaled $584 thousand in first quarter 2015, compared to $573 thousand for the same quarter in 2014 reflecting an effective tax rate of 30% for current quarter versus 29% for the first quarter in 2014. The lower tax rate in 2014 resulted from the recapture of a $35 thousand capital loss carryforward during the quarter.

Average total assets during the quarter amounted to $623 million, an increase of $32 million or 5% above the same quarter of the prior year. Average loan balances of $415 million were $19 million or 5% above prior year first quarter, while average securities balances of $146 million decreased $6 million or 4% as compared to first quarter 2014.

Average commercial loan balances for the quarter, including commercial real estate, increased $9 million or 3% above year ago levels. Average residential mortgage balances increased by $9 million or 12% over the prior year’s quarter. The increase of mortgage balances was the result of the bank originating and retaining some 15 year fixed rate mortgages. Average home equity balances decreased $147 thousand or less than 1%, and average consumer credit balances increased $1 million or 15% versus the same quarter of the prior year.

Nonperforming assets totaled $3.7 million or 0.88% of total loans plus other real estate, a decrease from $5.3 million or 1.30% of total loans plus other real estate at March 31, 2014. Delinquent loan balances as of March 31, 2015 amounted to 1.08% of total loans as compared to 1.57% at March 31, 2014.

Net loan charge-offs during first quarter 2015 were $81 thousand compared to first quarter 2014 net loan charge-offs of $205 thousand.

The Company funded $194 thousand in loan loss provision during the first quarter and the allowance for loan losses amounted to 1.07% of total loans on March 31, 2015. The ratio of the allowance for loan losses to nonperforming loans increased to 122% at March 31, 2015.

Average deposit balances grew by $27 million, or 6%, from the prior year’s first quarter. Average deposit balances for first quarter 2015 totaled $498 million. Within the deposit category, average noninterest-bearing account balances for the first quarter increased by $22 million, or 19% above the same period in the prior year. Average interest-bearing checking, money market and traditional savings balances increased $10 million or 4% from year ago levels, while average time deposit balances decreased $4 million or 3% from first quarter 2014. In addition to the changes in average deposit balances, the average balance of securities sold under repurchase agreement during the first quarter of 2015 grew by $1 million or 2% above the average for the same period in the prior year. The repurchase agreements, while considered short-term borrowings, are primarily tied to overnight customer sweep accounts.

Shareholders’ equity totaled $58.8 million on March 31, 2015 with 2.7 million common shares outstanding. The tangible equity to assets ratio amounted to 8.6% on March 31, 2015, as compared to 8.1% on March 31, 2014. The Company declared a common dividend of $.19 per share during the quarter. Based on the March 31, 2015 closing stock price of $23.00 per share, the Company’s annual dividend yield approximates 3.3%.

(a) - Net Interest income on a fully tax-equivalent (“FTE”) basis restates interest on tax-exempt securities and loans as if such interest were subject to federal income tax at the statutory rate. Net interest income on an FTE basis differs from net interest income under U.S. generally accepted accounting principles.
