ChoiceOne Financial Reports Second Quarter 2018 Results

Sparta, Mich. – July 25, 2018 – ChoiceOne Financial Services, Inc. (OTC:COFS), the parent company for ChoiceOne Bank, reported net income of $1,833,000 for the second quarter of 2018 compared to $1,635,000 in the same period in 2017. Diluted earnings per share was an adjusted $0.50 in the second quarter of 2018 compared to an adjusted $0.45 per share in the second quarter of the prior year. Diluted earnings per share for the six months ended June 30, 2018 was an adjusted $0.96 compared to an adjusted $0.85 for the six months ended June 30, 2017. Per share amounts have been adjusted for both 5% stock dividends paid on May 31, 2017 and May 31, 2018.

“With net income at a historical high for the first half of 2018, 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 expect our plans to open two additional full-service branch offices later this year in high-growth markets, including downtown Grand Rapids, to further add to our growth.”

Total assets remained steady at $630.3 million as of the end of the second quarter of 2018 compared to $630.1 million as of June 30, 2017. Net loans grew $15.9 million from June 30, 2017 to June 30, 2018, which along with higher interest rates on new loans led to total interest income of $6.1 million in the second quarter of 2018, which was $716,000 higher than the same period in 2017. Total deposits grew 1% or $3.6 million from June 30, 2017 to June 30, 2018.

ChoiceOne recorded no provision for loan losses in the second quarter of 2018, which was slightly lower than provision expense of $25,000 in the same period in the prior year. Nonperforming loans declined $590,000 from June 30, 2017 to June 30, 2018 as credit quality continued to remain a focal point for ChoiceOne.

Total noninterest income decreased $220,000 in the second quarter of 2018 compared to the same quarter in the prior year. Insurance and investment commissions were the largest component of the decline as a result of ChoiceOne’s sale of a majority of its investment book of business during the fourth quarter of 2017. Gains on sales of loans were also lower in the first quarter of 2018 than in the same period in the prior year as higher interest rates coupled with a low inventory of homes for sale in ChoiceOne’s market areas have negatively impacted mortgage originations. Partially offsetting these reductions in income were higher customer service charges in the second quarter of 2018 compared to the same period in 2017.

Total noninterest expense increased $332,000 in the second quarter of 2018 compared to the same period in 2017. Much of this growth 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 which will open later in 2018. Other noninterest expenses were also higher in the second quarter and first half of 2018 compared to the same periods in the prior year as a result of growth in loan related costs and other expenses.

ChoiceOne’s income tax expense decreased $236,000 in the second quarter of 2018 compared to the second quarter of 2017, which caused the effective tax rate to decline from 26% to 16%. This reduction in expense was due to the Tax Cut and Jobs Act passed in December of 2017.

“Although we have seen improvements in net income related to the decrease of ChoiceOne’s corporate tax rate, we have also benefited from management’s decision in the prior year to reduce the securities balance and redeploy funds into loan growth,” said Kelly Potes.
