ChoiceOne Financial Reports Third Quarter 2018 Results

Sparta, Mich. – October 24, 2018 – ChoiceOne Financial Services, Inc. (OTC:COFS), the parent company for ChoiceOne Bank, reported net income of $2,014,000 for the third quarter of 2018 compared to $1,720,000 in the same period in 2017. Diluted earnings per share was $0.55 in the third quarter of 2018 compared to an adjusted $0.48 per share in the third quarter of the prior year. Diluted earnings per share for the nine months ended September 30, 2018 was $1.52 compared to an adjusted $1.32 for the nine months ended September 30, 2017. Per share amounts have been adjusted for both 5% stock dividends paid on May 31, 2017 and May 31, 2018.

“Setting a new record with our year-to-date net income in the first nine months of this year, we are extremely pleased with the progress of our community bank,” said Kelly Potes, President and Chief Executive Officer of ChoiceOne Financial Services, Inc. “We just celebrated the grand opening of our new full-service, high-tech branch office in downtown Grand Rapids, Michigan which is a thriving market, which will continue to add to our growth.”

Total assets have grown to $650.4 million as of the end of the third quarter of 2018 compared to $630.8 million as of June 30, 2018. Net loans grew $6.1 million from June 30, 2018 to September 30, 2018, which along with higher interest rates on new loans led to total interest income of $6.3 million in the third quarter of 2018. This loan growth coupled with higher interest rates earned on both the loan and securities portfolios has helped total interest income for the nine months ended September 30, 2018 to grow $1.9 million or 11.5% compared to the nine months ended September 30, 2017.

ChoiceOne recorded no provision for loan losses in the third quarter of 2018 and nonperforming loans have declined $515,000 year to date 2018, as credit quality continues to remain a focal point for ChoiceOne.

Total noninterest income decreased $132,000 in the third quarter of 2018 and $436,000 in the nine months ended September 30, 2018 compared to the same periods in the prior year. Insurance and investment commissions were the largest component of the decline because of ChoiceOne’s sale of a majority of its investment book of business during the fourth quarter of 2017. Gains on sales of loans have also declined as higher interest rates coupled with a low inventory of homes for sale in ChoiceOne’s market areas have negatively impacted the level of mortgage originations. Gains on sales of securities were also lower in 2018 compared to the prior year as rising interest rates have caused an unrealized loss in many of ChoiceOne’s investment securities. Partially offsetting these reductions in income were higher customer service charges and changes in the market value of equity securities in the nine months ended September 30, 2018 compared to the same period in 2017. The implementation of Accounting Standard 2016-01 effective January 1, 2018, caused changes in the market value of equity securities to be recorded in noninterest income in 2018, in contrast with the treatment in prior years where changes were included in other comprehensive income.

Total noninterest expense increased $268,000 in the third quarter of 2018 and $898,000 in the first nine months of 2018 compared to the same periods in 2017. Much of this increase was caused by higher salaries and benefits expense related to annual wage increases and additional sales and retail staff in preparation for the two new branch locations in 2018. Other noninterest expenses were also higher in the third quarter and first nine months of 2018 compared to the same periods in the prior year due to growth in loan related costs, advertising and promotional expenses, and other expenses.

ChoiceOne’s income tax expense decreased $266,000 in the third quarter of 2018 and $676,000 in the first nine months of 2018 compared to the same periods in 2017, which caused the effective tax rate to decline from 26% in 2017 to 15% in 2018. This reduction in expense was due to the Tax Cut and Jobs Act passed in December of 2017.

“Later this year, we will celebrate the grand opening of our second, full-service branch office in Rockford, Michigan, another high-growth market for our bank,” said Potes. “With two new office locations by year end, we will have 14 branch offices throughout West Michigan to serve our growing customer base.”
