ChoiceOne Reports First Quarter 2026 Results

Sparta, Michigan – April 24, 2026 – ChoiceOne Financial Services, Inc. ("ChoiceOne", NASDAQ:COFS), the parent company for ChoiceOne Bank, reported financial results for the quarter ended March 31, 2026.

Highlights

"ChoiceOne delivered solid first-quarter performance, driven by strong net interest income, continued balance-sheet and expense discipline, and stable credit quality. Our loan pipeline looks strong as we continue to grow organically through deep customer relationships and executing on our strategic priorities across Michigan," said Kelly Potes, Chief Executive Officer.

ChoiceOne reported net income of $13,704,000 for the three months ended March 31, 2026, compared to net income of $13,867,000 and net loss of $13,906,000 for the three months ended December 31, 2025 and March 31, 2025, respectively. Net income excluding merger expenses, net of taxes, and merger related provision for credit losses, net of taxes, was $9,310,000 for the three months ended March 31, 2025. Diluted earnings per share were $0.91 for the three months ended March 31, 2026, compared to diluted earnings per share of $0.92 and diluted loss per share of $1.29 for the three months ended December 31, 2025 and March 31, 2025, respectively. Diluted earnings per share excluding merger expenses, net of taxes, and merger related provision for credit losses, net of taxes, was $0.86 for the three months ended March 31, 2025.

As of March 31, 2026, total assets were $4.4 billion, an increase of $89.2 million compared to March 31, 2025. The growth in total assets is primarily attributed to growth in securities and warehouse mortgage advances. This was partially offset by a reduction in the cash balance of $55.2 million during the twelve months ended March 31, 2026. Interest rates and balances on warehouse mortgage advances fluctuate with the national mortgage market and are short term in nature.

Core loans, which exclude held for sale loans and mortgage warehouse advances, declined by $30.9 million or an annualized 4.2% during the first quarter of 2026 and grew by $9.5 million or 0.3% during the twelve months ended March 31, 2026. Loan interest income increased $13.0 million in the first quarter of 2026 compared to the same period in 2025 and decreased $975,000 compared to the fourth quarter of 2025. The decrease from the fourth quarter of 2025 is partially due to a decline in interest income due to accretion from purchased loans during the first quarter of 2026 compared to the fourth quarter of 2025. Interest income for the three months ended March 31, 2026 includes $2.7 million of interest income due to accretion from purchased loans compared to $3.1 million for the three months ended December 31, 2025.

Interest income due to accretion from purchased loans increased GAAP net interest margin by 26 and 29 basis points in the first quarter of 2026 and fourth quarter of 2025, respectively. Of the amount recognized in the first quarter of 2026, $2.1 million was calculated using the effective interest rate method of amortization, while the remaining $597,000 resulted from accretion through 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 $5.8 million; however, actual results will be dependent on prepayment speeds and other factors. It is estimated that a total of $50.4 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, increased by $68.9 million as of March 31, 2026, compared to December 31, 2025. This increase is a combination of organic deposit growth and some seasonality in municipal deposits. Deposits, excluding brokered deposits, declined by $20.4 million as of March 31, 2026, compared to March 31, 2025. This decrease is primarily related to runoff of higher cost municipal CDs acquired in the Merger, partially offset by organic growth in other categories. 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 March 31, 2026, the total balance of borrowed funds from the FHLB was $185.0 million at a weighted average rate of 3.81%, with $165.0 million due within 12 months. At March 31, 2026, total available borrowing capacity secured by pledged assets was $1.2 billion. ChoiceOne can increase its borrowing capacity by utilizing unsecured federal fund lines and pledging additional assets. Uninsured deposits totaled $1.1 billion or 30.7% of deposits at March 31, 2026.

In the three months ended March 31, 2026, ChoiceOne’s annualized cost of deposits to average total deposits declined 3 basis points compared to the three months ended December 31, 2025 and declined 5 basis points compared to the three months ended March 31, 2025. The annualized cost of funds decreased by 13 basis points, from 1.86% to 1.73% in the three months ended March 31, 2026 compared to the same period in the prior year, primarily due to a decrease in higher cost local and brokered CDs. Interest expense on borrowings for the three months ended March 31, 2026 decreased by $9,000 compared to the same period in the prior year, despite a $32.2 million increase in the average balance borrowed, due to a reduction in rates. In the three months ended March 31, 2026, compared to the three months ended December 31, 2025, annualized cost of funds decreased 6 basis points from 1.79% to 1.73% due to the reductions in federal funds rate during the fourth quarter of 2025. With ChoiceOne’s already low cost of deposits and market conditions, additional reductions in the federal funds rate may not immediately result in a further reduction in cost of deposits.

There was no provision for credit losses on loans during the first quarter of 2026, due to a decline in loan balances and only $53,000 in net charge offs. The ratio of the allowance for credit losses to total loans (excluding loans held for sale) was 1.19% on March 31, 2026 compared to 1.18% on December 31, 2025. Asset quality continues to remain strong, with annualized net loan charge-offs to average loans of 0.01% for the first quarter of 2026. Nonperforming loans to total loans (excluding loans held for sale) increased to 1.01% as of March 31, 2026 compared to 0.98% as of December 31, 2025. Notably, 0.61% of the nonperforming loans to total loans (excluding loans held for sale) is attributed to certain purchased loans which were identified prior to the Merger as having credit deterioration.

ChoiceOne uses interest rate swaps to manage interest rate exposure to certain fixed rate assets and variable rate liabilities. During the first quarter of 2026, ChoiceOne exited $351.0 million of pay‑fixed interest rate swaps with an average coupon of approximately 3.12%. This resulted in a small gain that was applied to the basis of the hedged bonds and a $4.6 million realized gain that will be amortized into interest expense over approximately six years. After evaluating multiple rate scenarios, we determined that our interest rate risk profile and overall balance sheet flexibility are improved without the pay‑fixed interest rate swaps, and we believe this action better aligns our interest rate posture with long‑term value creation for shareholders. Following this exit, the asset sensitivity of the bank is reduced and balance sheet derivatives are no longer a significant percentage of assets. ChoiceOne has approximately $29.0 million of pay-fixed interest rate swaps with a weighted average coupon of 3.52%. These swaps were entered into in the third quarter of 2025 to hedge interest rate risk on newly purchased agency mortgage backed securities.

At March 31, 2026, shareholders’ equity was $470.0 million, an increase from $427.1 million on March 31, 2025. ChoiceOne repurchased 25,116 shares of stock for a net cost of $775,000 in the fourth quarter of 2025 and 50,000 shares of stock for a net cost of $1.4 million during the first quarter of 2026 under our existing share repurchase plan. The repurchase plan has 300,272 shares remaining to purchase as of March 31, 2026. The repurchase 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 March 31, 2026, compared to 11.9% on March 31, 2025.

Noninterest income declined by $282,000 in the three months ended March 31, 2026, compared to the three months ended December 31, 2025. This decline was partly driven by lower interchange income and lower gains on sales of loans, which are both affected by seasonality. Noninterest income also declined in the first quarter of 2026 compared to the fourth quarter of 2025 due to losses on the sales of securities. These declines were offset by an increase from the change in market value of equity securities during the first quarter of 2026 compared to the fourth quarter of 2025. Noninterest income increased by $893,000 in the three months ended March 31, 2026 compared to the three months ended March 31, 2025. This increase was partly driven by higher customer service charges and interchange income, which rose due to increased volume from the Merger. Insurance and investment commissions income also increased as a result of higher estate settlement fees and customers obtained from the Merger.

These increases were offset by the aforementioned loss on sales of securities in the first quarter of 2026.

Noninterest expense increased by $427,000 for the three months ended March 31, 2026, compared to the three months ended December 31, 2025. The increase was due to higher FDIC insurance costs, professional fees, and other expenses including Michigan state taxes, offset by lower salaries and benefits costs. Noninterest expense declined by $9.9 million for the three months ended March 31, 2026, compared to the three months ended March 31, 2025. The decline was largely due to merger-related expenses of $17.2 million in the three months ended March 31, 2025, offset by higher salaries and benefits expense, occupancy and equipment expense and intangible amortization expense in the three months ended March 31, 2026, compared to the same period in 2025. ChoiceOne will continue to invest in its talented staff, technology and footprint while prioritizing operational efficiency and disciplined investment. ChoiceOne has secured a location in Troy, MI and expects to open a full service branch and lending office later in 2026. We believe this new office will help us continue our strong growth in an attractive market.

ChoiceOne’s first‑quarter 2026 tax expense was reduced by $200,000 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 2026 to reduce tax expense.

“We ended the first quarter with solid capital and liquidity and an efficient funding mix, keeping us well positioned to support clients and create long-term value," said Kelly Potes, Chief Executive Officer. "As we progress through 2026, we remain focused on disciplined growth, strengthening customer relationships, and executing on opportunities across our markets."
