ChoiceOne Financial Reports First Quarter 2018 Results

Sparta, Mich. – April 25, 2018 – ChoiceOne Financial Services, Inc. (OTC:COFS), the parent company for ChoiceOne Bank, reported net income of $1,658,000 for the first quarter of 2018 compared to $1,446,000 in the same period in 2017. Earnings per share were $0.48 in the first quarter of 2018 compared to an adjusted $0.42 per share in the first quarter of the prior year. Per share amounts for 2017 have been adjusted for the 5% stock dividend paid on May 31, 2017.

“I am extremely pleased to once again report strong net income for the first quarter of 2018,” said Kelly Potes, President and Chief Executive Officer of ChoiceOne Financial Services, Inc. “This will be an exciting year for us as we continue our expansion into West Michigan with a new full-service branch opening in downtown Grand Rapids, and another full-service branch opening in the Rockford market, both later this year. In addition to our physical presence, we continue to expand our digital technology, partnering with Michigan-based fintech companies.”

Total assets grew to $622.7 million as of March 31, 2018, compared to $617.7 million as of March 31, 2017. Net loans have grown $12.8 million since March 31, 2017, which along with higher interest rates on new loans led to total interest income of $5.7 million in the first quarter of 2018, which was $561,000 higher than the same period in 2017. Total deposits grew 5% or $23.9 million from March 31, 2017 to March 31, 2018, which helped in the funding of loans.

ChoiceOne recorded a $35,000 provision for loan losses during the first quarter of 2018 to keep up with anticipated loan growth. Nonperforming loans declined $186,000 from March 31, 2017 to March 31, 2018 as credit quality continued to remain a focal point for ChoiceOne.

Total noninterest income decreased $106,000 in the first quarter of 2018 compared to the same quarter in the prior year. Insurance and investment commissions were the largest component of the decline as ChoiceOne sold a majority of its investment book of business during the fourth quarter of 2017. Gains on sales of securities were also lower in the first quarter of 2018 than in the same period in the prior year as higher interest rates have negatively impacted ChoiceOne’s market value of securities. Partially offsetting these reductions in income were higher customer service charges and gains on sales of loans in the first quarter of 2018 compared to the same period in 2017. In spite of higher long-term interest rates and a low inventory of homes available for sale in ChoiceOne’s primary market areas, ChoiceOne’s mortgage loan originators generated more mortgage sales volume in the first quarter of 2018 than the first quarter in the prior year.

Total noninterest expense increased $296,000 in the first quarter of 2018 compared to the same period in 2017. Much of this growth was caused by higher salaries and benefits expense, part of which was due to staffing additions in preparation for two additional branch locations which will open later in 2018. Other noninterest expenses were also higher in the first quarter of 2018 compared to the same quarter in the prior year. Contributing factors were growth in advertising and other miscellaneous expenses.

ChoiceOne’s income tax expense decreased $174,000 in the first quarter of 2018 compared to the first quarter of 2017, which caused the effective tax rate to decline from 25% to 15%. This reduction in expense was due to the Tax Cut and Jobs Act passed in December of 2017.
