ChoiceOne Reports Second Quarter 2026 Results

Sparta, Michigan – July 24, 2026 – ChoiceOne Financial Services, Inc. ("ChoiceOne", NASDAQ:COFS), the parent company for ChoiceOne Bank, reported financial results for the quarter ended June 30, 2026.

Highlights

“ChoiceOne delivered solid second quarter results, highlighted by loan growth, stable credit quality, and continued capital accretion,” said Kelly Potes, Chief Executive Officer. “Our disciplined approach to balance sheet management is improving our earning asset mix and interest rate positioning, while supporting continued momentum through the remainder of 2026.”

ChoiceOne reported net income of $12,463,000 and $26,167,000 for the three and six months ended June 30, 2026, respectively, compared to net income of $13,534,000 and a net loss of $372,000 for the three months and six months ended June 30, 2025, respectively. Diluted earnings per share were $0.83 and $1.74 for the three and six months ended June 30, 2026, compared to diluted earnings per share of $0.90 and diluted loss per share of $0.03 for the three and six months ended June 30, 2025, respectively. Second quarter results included a pre-tax securities loss of approximately $1.9 million, which reduced diluted earnings per share by approximately $0.10, as ChoiceOne repositioned lower-yielding municipal securities to fund loan growth and improve its interest rate profile.

As of June 30, 2026, total assets were $4.5 billion, an increase of $146.6 million compared to June 30, 2025. The growth in total assets is primarily attributed to growth in core loans, securities and warehouse mortgage advances. This growth was partially offset by a reduction in the cash balance of $67.6 million during the twelve months ended June 30, 2026.

Core loans, which exclude held for sale loans and mortgage warehouse advances, increased by $87.1 million or an annualized 11.9% during the second quarter of 2026 and grew by $101.5 million or 3.5% during the twelve months ended June 30, 2026. Of this growth approximately $40.0 million was due to a purchase of seasoned, high quality adjustable rate mortgages from another community bank made during the quarter. Loan interest income increased $703,000 in the second quarter of 2026 compared to the first quarter of 2026 and decreased $187,000 compared to the second quarter of 2025. The decrease from the second quarter of 2025 is partially due to a decline in interest income due to accretion from purchased loans during the second quarter of 2026 compared to the second quarter of 2025. Interest income due to accretion from purchased loans was approximately $2.4 million during the second quarter of 2026 compared to $3.5 million for the three months ended June 30, 2025. Interest income due to accretion from purchased loans increased GAAP net interest margin by 24 and 36 basis points in the second quarter of 2026 and the second quarter of 2025, respectively. Of the amount recognized in the second quarter of 2026, $2.0 million was calculated using the effective interest rate method of amortization, while the remaining $433,000 resulted from unexpected payoffs and paydowns of loans with an associated fair value mark. Estimated interest income due to accretion from purchased loans for the remainder of 2026 using the effective interest method of amortization is $3.8 million; however, actual results will be dependent on prepayment speeds and other factors. It is estimated that a total of $48.0 million remains to be recognized as interest income due to accretion from purchased loans over the life of the purchased loans portfolio.

Deposits, excluding brokered deposits, decreased by $55.4 million as of June 30, 2026, compared to March 31, 2026. This decline is largely due to seasonality in municipal deposits as municipal operational balances fluctuate with the timing of tax receipts. Municipal deposits decreased by approximately $95.0 million during the quarter, which is consistent with historical fluctuations. Deposits, excluding brokered deposits, increased by $22.2 million as of June 30, 2026, compared to June 30, 2025. This increase is primarily organic growth in interest bearing and savings accounts offset by a decline in higher interest certificate of deposit accounts. ChoiceOne continues to be proactive in managing its liquidity position by using brokered deposits and short-term FHLB advances to ensure ample liquidity. As of June 30, 2026, the total balance of borrowed funds from the FHLB was $295.0 million at a weighted average rate of 3.80%, with $275.0 million due within 12 months. At June 30, 2026, total available borrowing capacity secured by pledged assets was $1.1 billion. ChoiceOne can increase its borrowing capacity by utilizing unsecured federal fund lines and pledging additional assets. Uninsured deposits totaled $1.2 billion or 33.1% of deposits at June 30, 2026.

In the three months ended June 30, 2026, ChoiceOne's annualized cost of deposits to average total deposits increased four basis points to 1.58% from 1.54% for the three months ended March 31, 2026. The annualized cost of funds increased four basis points to 1.77% for the three months ended June 30, 2026, from 1.73% in the prior quarter, primarily driven by higher rates on interest-bearing demand deposits and savings deposits offset by lower rates on certificates of deposit, borrowings, subordinated debentures, and brokered deposits. The average balance of certificates of deposit declined $14.2 million during the quarter. Interest expense on borrowings increased $58,000 compared to the first quarter of 2026 as average borrowings increased $5.1 million. ChoiceOne’s deposit costs may have slight upward pressure as new and repriced deposits carry rates above the existing portfolio average.

ChoiceOne incurred $550,000 provision for credit losses on loans during the second quarter of 2026, due to the increase in loan balances and $309,000 in net charge offs. The ratio of the allowance for credit losses to total loans (excluding loans held for sale) was 1.16% on June 30, 2026 compared to 1.19% and 1.18% on March 31, 2026 and December 31, 2025, respectively. Asset quality continues to remain strong, with annualized net loan charge-offs to average loans of 0.04% for the second quarter of 2026. Nonperforming loans to total loans (excluding loans held for sale) increased to 1.07% as of June 30, 2026 compared to 1.01% as of March 31, 2026. Notably, 0.49% of the nonperforming loans to total loans (excluding loans held for sale) is attributed to certain purchased loans which were identified prior to acquisition as having credit deterioration. In addition, 30.6% of the nonperforming loans carry partial government guarantees from the SBA or USDA.

At June 30, 2026, shareholders’ equity was $482.7 million, an increase from $431.8 million on June 30, 2025. ChoiceOne repurchased 35,000 shares of stock for a net cost of $1.1 million in the second quarter of 2026 and 75,116 shares [collectively] during the first quarter of 2026 and the fourth quarter of 2025 for a net cost of $2.2 million under our existing share repurchase plan. The repurchase plan has 265,272 shares remaining to purchase as of June 30, 2026. The repurchase of shares reflects our view that our capital position is healthy and the repurchase of shares is in the best interest of our shareholders. ChoiceOne Bank continues to be “well-capitalized,” with a total risk-based capital ratio of 12.9% as of June 30, 2026, compared to 12.4% on June 30, 2025.

Noninterest income for the three months ended June 30, 2026 decreased $1.6 million to $4.9 million compared to $6.5 million for the same period in 2025. The decline was primarily driven by a $1.9 million loss on the sale of securities during the second quarter of 2026, compared to no securities gains or losses in the prior-year period. In late June 2026 ChoiceOne sold approximately $25 million of municipal securities with a tax-equivalent yield of 2.28% for a pre-tax loss of $1.9 million. The sale of securities was undertaken to provide funding for the purchase of adjustable-rate residential mortgages and improve ChoiceOne’s overall interest rate profile. Partially offsetting this decline were increases in customer service charges and interchange income and insurance and investment commissions. Compared to the first quarter of 2026, noninterest income declined $876,000, primarily due to the increase in net losses on sales of securities. Noninterest income for the six months ended June 30, 2026 decreased $671,000, to $10.8 million compared to $11.4 million for the same period in 2025.

Noninterest expense for the three months ended June 30, 2026 increased $545,000, or 2.1%, to $26.1 million compared to $25.5 million for the same period in 2025. The increase was primarily attributable to higher salaries and benefits expense, partially offset by lower intangible amortization expense. Compared to the first quarter of 2026, noninterest expense increased $275,000, reflecting higher salaries and benefits expenses and data processing costs, partially offset by lower occupancy and equipment and intangible amortization expenses. Noninterest expense for the six months ended June 30, 2026 decreased $9.3 million, to $51.8 million compared to $61.2 million for the same period in 2025. The decrease was primarily attributable to the absence of $17.4 million of merger-related expenses incurred during the prior-year period. Excluding merger-related expenses, noninterest expense increased due to higher salaries and benefits, occupancy and equipment, data processing, professional fees, and other operating expenses associated with the Company's growth and integration activities. ChoiceOne expects to open a full service branch and lending office in Troy, MI later in 2026. ChoiceOne currently serves customers throughout Southeast Michigan and expects the Troy office to further support commercial lending and treasury management growth initiatives.

ChoiceOne’s year to date 2026 tax expense was reduced by $400,000 as a result of purchasing a transferable tax credit that will be applied to 2026 income taxes. Management intends to purchase similar sized transferable tax credits in the remainder of 2026 to reduce tax expense.

“As we enter the second half of 2026, we remain focused on disciplined growth, operational efficiency, and prudent capital management,” said Kelly Potes, Chief Executive Officer. “We believe this balanced approach positions ChoiceOne to build on our momentum and create long-term value for our customers, communities, and shareholders.”
