· Net income of $16.9 million and $35.1 million for the three and six months ended June 30, 2025, respectively

· Earnings per common share of $1.71 and $3.53 for the three and six months ended June 30, 2025, respectively

· Annualized return on average assets of 1.54% and 1.59% for the three and six months ended June 30, 2025, respectively

· Quarterly cash dividend of $0.45 per share declared, matching the prior quarter and 12.5% higher than the prior-year second quarter

MANITOWOC, Wis, July 18, 2025 -- Bank First Corporation (NASDAQ: BFC) (“Bank First” or the “Bank”), the holding company for Bank First, N.A., reported net income of $16.9 million, or $1.71 per share, for the second quarter of 2025, compared with net income of $16.1 million, or $1.59 per share, for the prior-year second quarter. For the six months ended June 30, 2025, Bank First earned $35.1 million, or $3.53 per share, compared to $31.5 million, or $3.10 per share for the same period in 2024.

“Bank First continues to benefit from recent moves towards normalization of the yield curve after an extended period of yield curve inversion,” stated Mike Molepske, Chairman and CEO of Bank First. “While we pride ourselves on being interest rate neutral, which minimizes the impact of changes in interest rates on our earnings, a normalized yield curve benefits the entire banking industry. If this move towards normalization continues, Bank First should see an improving net interest margin over the coming months and years.”

Operating Results

Net interest income (“NII”) during the second quarter of 2025 was $36.7 million, up $0.2 million from the previous quarter and up $3.7 million from the second quarter of 2024. The impact of net accretion and amortization of purchase accounting related to interest-bearing assets and liabilities from past acquisitions (“purchase accounting”) increased NII by $0.6 million, or $0.05 per share after tax, during the second quarter of 2025, compared to $1.0 million, or $0.08 per share after tax, during the previous quarter and $1.2 million, or $0.09 per share after tax, during the second quarter of 2024.

Net interest margin (“NIM”) was 3.72% for the second quarter of 2025, compared to 3.65% for the previous quarter and 3.63% for the second quarter of 2024. NII from purchase accounting increased NIM by 0.03%, 0.10% and 0.13% for each of these periods, respectively. The Bank’s NIM continues to benefit from new and renewed loans pricing at higher yields while deposits, particularly certificates, continue to reprice lower. Rates earned on average earning assets increased 10 basis points while rates paid on average interest-bearing deposits decreased 15 basis points from the second quarter of 2024 to the second quarter of 2025. NIM improved through the second quarter of 2025, with total NIM for the month of June 2025 coming in at 3.77% and NIM net of the impact of purchase accounting coming in at 3.70%.

Bank First recorded a provision for credit losses of $0.2 million during the second quarter of 2025, compared to $0.4 million during the previous quarter. The Bank did not record a provision for credit losses during the second quarter of 2024. Provision expense was $0.6 million for the first six months of 2025 compared to $0.2 million for the same period during 2024.

Noninterest income was $4.9 million for the second quarter of 2025, compared to $6.6 million and $5.9 million for the prior quarter and second quarter of 2024, respectively. Income provided by the Bank’s investment in Ansay & Associates, LLC totaled $1.2 million during the second quarter of 2025, matching the prior quarter but down $0.2 million from the prior-year second quarter. The Bank also experienced a $0.1 million negative valuation adjustment to its mortgage servicing rights asset during the second quarter of 2025 which compared unfavorably to $0.2 million and $0.3 million in positive valuation adjustments during the prior quarter and prior-year second quarter, respectively. Finally, the Bank benefited from a $1.0 million gain during the first quarter of 2025 and a $0.4 million gain during the second quarter of 2024 from death benefits on bank-owned life insurance policies, creating a negative variance in other non-interest income for the previous quarter and prior-year second quarter.

Noninterest expense totaled $20.8 million in the second quarter of 2025, compared to $20.6 million during the prior quarter and $19.1 million during the second quarter of 2024. Personnel expense remained well-managed, down $0.6 million from the prior quarter but up $0.4 million from the prior-year second quarter, the result of standard cost-of-living and merit increases year-over-year. Occupancy, equipment and office expense was elevated during the second quarter of 2025, up $0.3 million from the prior quarter and $0.6 million from the prior-year second quarter, the result of expenses from multiple branch remodels and the opening of a new branch in Sturgeon Bay, WI during the most recent quarter. Data processing expense was once again impacted in the most recent quarter by elevated expenditures related to the Bank’s upgrade of its digital banking platform after experiencing relatively light expenditures related to these projects in the first quarter of 2025. Outside service fees increased by $0.3 million from the prior quarter but were down $0.3 million from the second quarter of 2024. Outside service fees during the second quarter of 2025 include a $0.1 million commission related to the sale of a former branch building, which resulted in a $0.2 million gain on sale, and $0.1 million in personnel recruitment fees. The second quarter of 2024 included $0.4 million in commissions related to sales of former branch buildings, which resulted in $0.5 million in gains, leading to the improved year-over-year variance.

Total assets were $4.37 billion at June 30, 2025, a $130.0 million decline from December 31, 2024, but a $219.3 million increase from June 30, 2024.

Noninterest-bearing demand deposits comprised 27.5% of the Bank’s total deposits at June 30, 2025, compared to 27.4% and 28.7% at December 31 and June 30, 2024, respectively.

These forward-looking statements are not historical facts and are based upon current expectations, estimates, and projections, many of which, by their nature, are inherently uncertain and beyond Bank First’s control. The inclusion of these forward-looking statements should not be regarded as a representation by Bank First or any other person that such expectations, estimates, and projections will be achieved. Accordingly, Bank First cautions shareholders and investors that any such forward-looking statements are not guarantees of future performance and are subject to risks, assumptions, and uncertainties that are difficult to predict. Actual results may prove to be materially different from the results expressed or implied by the forward-looking statements. A number of factors could cause actual results to differ materially from those contemplated by the forward-looking statements including, without limitation, (1) business and economic conditions nationally, regionally and in our target markets, particularly in Wisconsin and the geographic areas in which we operate, (2) changes in government interest rate policies, (3) our ability to effectively manage problem credits, (4) the risks associated with Bank First’s pursuit of future acquisitions, (5) Bank First’s ability to successful execute its various business strategies, including its ability to execute on potential acquisition opportunities, and (6) general competitive, economic, political, and market conditions.
