Sparta, Michigan - James Bosserd, President and Chief Executive Officer of ChoiceOne Financial Services, Inc., announced that ChoiceOne reported net income of $904,000 for the second quarter of 2011 compared to $669,000 in the same period last year. Earnings per share were $0.28 for the second quarter of 2011 compared to $0.20 for the same quarter in 2010. Net income for the first six months of 2011 was $1,608,000 or $0.49 per share, compared to $1,313,000 or $0.40 per share in the first half of 2010. Mr. Bosserd commented "Our earnings continue to improve. We have seen growth in our deposit base which has helped us to improve both net interest income and noninterest income."

Net interest income was $262,000 higher in the second quarter of 2011 and $547,000 higher in the first half of 2011 than in the same periods in 2010. Average interest-earning assets were $13.0 million higher in the first six months of 2011 than in the same period in 2010. The average balance of securities was $20.3 million higher as securities were purchased due to sluggish loan demand. Although loans grew in the second quarter of 2011, the average balance of loans was $2.3 million lower in the first half of 2011 than in the same period in the prior year. ChoiceOne's net interest spread was 20 basis points higher in the first six months of 2011 than in the same period in 2010. This was caused by rate reductions in funding costs being larger than rate reductions on earning assets.

The provision for loan losses was $850,000 in the second quarter of 2011 and $1,850,000 in the first six months of 2011, compared to $1,000,000 and $2,050,000, respectively, in the same periods in the prior year. The decrease in the provision for loan losses in the second quarter of 2011 compared to the same quarter in 2010 was due to slightly lower net charge-offs in the second quarter of the current year than the same period in the prior year and a decrease in nonperforming loans in the second quarter of 2011. Net charge-offs were $779,000 in the second quarter and $1,777,000 in the first half of 2011, compared to $830,000 and $1,515,000, respectively, in the same periods in the prior year. ChoiceOne's allowance for loan losses was 1.53% of total loans as of June 30, 2011, compared to 1.51% as of March 31, 2011 and 1.49% as of December 31, 2010. Total nonperforming loans were $7.9 million as of June 30, 2011, compared to $9.8 million as of March 31, 2011 and $8.4 million as of December 31, 2010. The change in nonperforming loans in the second quarter of 2011 was caused by a decrease of $2.3 million in nonaccrual loans.

Noninterest income of $1,624,000 in the second quarter of 2011 and $3,024,000 in the first six months of 2011 represented increases of $293,000 and $186,000, respectively, when compared to the same periods in 2010. Customer service charges were $110,000 higher in the second quarter and $191,000 higher in the first half of 2011 compared to the same periods in 2010 as a result of growth in debit card transactions. Gains on loan sales were $64,000 higher and $97,000 higher in the second quarter and first six months of 2011, respectively, compared to the same periods in the prior year due to increased residential real estate loan production in 2011. Gains on sales of securities were $335,000 lower in the first half of 2011 than the same period in 2010. Approximately $386,000 of securities gains were recognized in the first quarter of 2010 from sales of preferred stock. Gains or losses on asset sales improved $92,000 in the second quarter and $143,000 in the first six months of 2011 compared to the same

periods in the prior year. Gains were recognized on the sale of other real estate owned and repossessed assets in 2011, in contrast to 2010 where losses were recorded.

Noninterest expense of $4,067,000 in the second quarter of 2011 and $7,934,000 in the first six months of 2011 represented increases of $343,000 and $512,000, respectively, when compared to the same periods in 2010. Salaries and benefits expense grew $112,000 in the second quarter and $240,000 in the first half of 2011 compared to the same periods in 2010 as a result of staffing additions, incentives paid, commission expense from higher mortgage originations, and the Company's 401(k) plan contribution. The increase in noninterest expense was also due to higher costs in training, recruiting, insurance and loan expenses.

Total assets decreased $12.3 million in the second quarter of 2011 and have grown $22.2 million in the twelve months ended June 30, 2011. Cash and cash equivalents declined $11.9 million in the second quarter of 2011 due to an $11.8 million reduction in total deposits during the quarter. The drop in deposits was due to a $12.4 million decrease in funds with municipal depositors. Checking, money market, and savings deposits decreased $1.0 million in the second quarter of 2011 while total certificates of deposit decreased $10.8 million. Securities were virtually unchanged in the second quarter of 2011 and have grown $20.2 million in the twelve months ended June 30, 2011 as funds were invested to maintain earning assets. Loans, though lower than the balance as of the end of 2010, increased $1.9 million in the second quarter of 2011 and have grown $2.5 million since June 30, 2010 due to calling efforts by ChoiceOne's officers and marketing of consumer loan products.

These statements reflect management's current beliefs as to the expected outcomes of future events and are not guarantees of future performance. These statements involve certain risks, uncertainties and assumptions ("risk factors") that are difficult to predict with regard to timing, extent, likelihood and degree of occurrence. Therefore, actual results and outcomes may materially differ from what may be expressed or forecasted in such forward-looking statements.
