Sparta, Michigan - October 26, 2012 - ChoiceOne Financial Services, Inc., parent company for ChoiceOne Bank, announced that ChoiceOne reported net income of $1,122,000 for the third quarter of 2012 compared to $886,000 in the same period last year. Earnings per share were $0.34 for the third quarter of 2012 compared to $0.27 for the third quarter in 2011. Net income for the first nine months of 2012 was $3,158,000 or $0.96 per share, compared to $2,494,000 or $0.76 per share in the first nine months of 2011.

"We are pleased to report increased net income and record quarterly earnings", said James Bosserd, President and Chief Executive Officer of ChoiceOne Financial Services, Inc. "In the third quarter of 2012, we continued to grow cash deposits, which allowed us to fund additional earning assets. Our residential mortgage lending volume was outstanding as borrowers took advantage of low interest rates. We continued our commitment to community banking, which we believe includes taking in local deposits and investing them back into our communities by making loans to our neighboring families and businesses as a local bank."

The increase in net income in both the third quarter and first nine months of 2012 compared to the same periods in 2011 was due to a lower provision for loan losses and higher noninterest income. These were partially offset by lower net interest income and higher noninterest expense in the third quarter and first nine months of 2012 compared to the same periods in 2011.

Net interest income was $11,000 lower in the third quarter of 2012 and $119,000 lower in the first nine months of 2012 than in the same periods in 2011. Average earning assets were $14.8 million higher in the first nine months of 2012 than in the same period in 2011. The average balance of loans was $7.6 million lower, primarily due to payments received on agricultural and other commercial loans. The average balance of securities was $23.6 million higher as securities were purchased to provide growth in earning assets. ChoiceOne's net interest spread was 16 basis points lower in the first nine months of 2012 than in the same period in 2011 because of the low interest rate environment that currently exists. The interest spread decrease was caused by reductions in rates earned on loans and investment securities that were greater than rate decreases on funding sources.

The provision for loan losses was $500,000 in the third quarter of 2012 and $1,975,000 in the first nine months of 2012 compared to $950,000 and $2,800,000, respectively, in the same periods in 2011. The decrease in the provision in 2012 was based on lower net charge-offs. Net charge-offs were $336,000 in the third quarter and $1,415,000 in the first nine months of 2012, compared to $918,000 and $2,695,000, respectively, in the same periods in 2011. ChoiceOne's allowance for loan losses was 1.91% of total loans as of September 30, 2012, compared to 1.84% as of June 30, 2012 and 1.63% as of December 31, 2011. Total nonperforming loans were $7.5 million as of September 30, 2012, compared to $8.3 million as of June 30, 2012 and $6.7 million as of December 31, 2011. The increase in nonperforming loans since the end of 2011 was due to an increase of $0.7 million in the balance of troubled debt restructurings. Of the total of $4.0 million of loans classified as troubled debt restructurings as of September 30, 2012, approximately $2.9 million are current as to payments and performing as to their new terms.

Noninterest income increased $142,000 in the third quarter and $524,000 in the first nine months of 2012 compared to the same periods in 2011. Customer service charges dropped $23,000 and $152,000 in the third quarter and first nine months of 2012, respectively, compared to the same periods in the prior year as a result of reduced overdraft fees, which was partially offset by growth in debit card fee income. Gains on sales of loans grew $321,000 in the third quarter and $810,000 in the first nine months of 2012 compared to the same periods in 2011 as mortgage

refinancing activity was stimulated by low interest rates for long-term fixed rate mortgage loans. Gains on sales of securities increased $16,000 in the third quarter and $240,000 in the first nine months of 2012 over the same periods in 2011 due to a higher level of sales activity. Net losses on sales of other assets were up $108,000 in the third quarter of 2012 and $389,000 in the first nine months of 2012 over the same periods in the prior year as a result of write-downs of foreclosed properties.

Noninterest expense increased $249,000 in the third quarter and $341,000 in the first nine months of 2012 compared to the same periods in 2011. Salaries and benefits expense grew $139,000 in the third quarter and $281,000 in the first nine months of 2012 compared to the same periods in 2011 as a result of higher commission expense related to mortgage originations, incentives and profit sharing, and health insurance costs. Data processing expense increased $67,000 in the third quarter and $77,000 in the first nine months of 2012 compared to the same periods in 2011 as a result of higher software maintenance costs. Professional fees grew $52,000 in the third quarter of 2012 and $68,000 in the first nine months of 2012 compared to the same periods in 2011 due to increased use of outside consultants. FDIC insurance cost decreased $28,000 in the third quarter and $115,000 in the first nine months of 2012 compared to the same periods in the prior year due to a change in the assessment base for insurance beginning in the second quarter of 2011.

Total assets grew $13.7 million in the third quarter of 2012 and $23.3 million in the twelve months ended September 30, 2012. Cash and cash equivalents increased $6.9 million in the third quarter of 2012 and $16.9 million in the last twelve months due to deposit growth. Securities increased $8.6 million in the third quarter of 2012 and $27.7 million in the last twelve months as the reduction in loan balances and deposit growth provided funds that were used for securities purchases. Net loans declined $2.5 million in the third quarter of 2012 as a result of loan pay-downs and have decreased $20.2 million in the twelve months ended September 30, 2012. Commercial and industrial loans grew $2.0 million in the third quarter of 2012, while commercial real estate loans and agricultural loans declined $4.2 million and $0.7 million in the same period, respectively.
