FOR IMMEDIATE RELEASE

Bank First Announces Net Income for the Third Quarter of 2023

Net income of $14.8 million and $39.6 million for the three and nine months ended September 30, 2023, respectively

Earnings per common share of $1.43 and $3.89 for the three and nine months ended September 30, 2023, respectively

Annualized return on average assets of 1.44% and 1.31% for the three and nine months ended September 30, 2023, respectively

Quarterly cash dividend of $0.30 per share declared, matching the prior quarter and a 20.0% increase from the prior-year third quarter

MANITOWOC, Wis, October 17, 2023 -- Bank First Corporation (NASDAQ: BFC) (“Bank First” or the “Bank”), the holding company for Bank First, N.A., reported net income of $14.8 million, or $1.43 per share, for the third quarter of 2023, compared with net income of $10.5 million, or $1.26 per share, for the prior-year third quarter. For the nine months ended September 30, 2023, Bank First earned $39.6 million, or $3.89 per share, compared to $32.4 million, or $4.15 per share for the same period in 2022. After removing the impact of one-time expenses related to acquisitions as well as gains and losses on sales of securities and other real estate owned (“OREO”), the Bank reported adjusted net income (non-GAAP) of $15.1 million, or $1.46 per share, for the third quarter of 2023, compared with $14.0 million, or $1.70 per share, for the prior-year third quarter. For the first nine months of 2023, adjusted net income (non-GAAP) totaled $44.4 million, or $4.38 per share, compared to $36.6 million, or $4.69 per share for the same period in 2022.

Operating Results

Net interest income (“NII”) during the third quarter of 2023 was $34.1 million, down $0.2 million from the previous quarter but up $6.4 million from the third quarter of 2022. The impact of purchase accounting increased NII by $1.8 million, or $0.13 per share after tax, during the third quarter of 2023, compared to $2.5 million, or $0.18 per share after tax, during the previous quarter and $0.7 million, or $0.07 per share after tax, during the third quarter of 2022.

Net interest margin (“NIM”) was 3.71% for the third quarter of 2023, compared to 3.77% for the previous quarter and 3.63% for the third quarter of 2022. NII from purchase accounting increased NIM by 0.19%, 0.27% and 0.10% for each of these periods, respectively. While the Bank’s average rate paid on interest-bearing liabilities has continued to rise throughout 2023, increasing average rates earned on interest-earning assets as well as the beneficial impact of the Bank’s continuing high percentage of noninterest-bearing deposits (32.1% of the Bank’s total core deposits at September 30, 2023) have allowed the Bank’s net interest margin, excluding purchase accounting impacts, to expand quarter-over-quarter for the last two quarters.

Bank First did not record a provision for credit losses during the third quarter of 2023, matching the previous quarter and the third quarter of 2022. Provision expense was $4.2 million for the first nine months of 2023 compared to $1.7 million for the same period during 2022. The acquisition of the loan portfolio of Hometown Bancorp, Ltd. (“Hometown”) during the first quarter of 2023 resulted in a day 1 provision for credit losses expense of $3.6 million as required under the Current Expected Credit Losses (“CECL”) methodology, which the Bank adopted on January 1, 2023. The lack of a provision for credit losses during the second and third quarter of 2023 was the result of continued strong asset quality metrics discussed later in this release. Recoveries of previously charged-off loans exceeded currently charged-off loans by $0.1 million through the first nine months of 2023, compared to recoveries exceeding charge-offs by $1.0 million through the first nine months of 2022.

Noninterest income was $5.3 million for the third quarter of 2023, compared to $4.6 million and $5.2 million for the prior quarter and third quarter of 2022, respectively. Service charge income increased by $0.1 million, or 3.1%, and $0.4 million, or 31.7%, from the prior quarter and prior-year third quarter, respectively, as a result of the added scale from the acquisitions of Denmark Bancshares, Inc. (“Denmark”) and Hometown. Income provided by the Bank’s investment in Ansay & Associates increased by $0.1 million from the prior-year third quarter while declining $0.2 million from the prior quarter. Income from this investment increased by $0.5 million, or 21.4%, through the first nine months of 2023 compared to the same period in 2022. Loan servicing income from loans previously sold to the secondary market with servicing rights, and therefore servicing income, retained by the Bank matched the prior quarter but increased by $0.2 million, or 49.5% from the prior-year third quarter. Sold but serviced loan portfolios acquired from Denmark and Hometown totaled $159.5 million and $343.6 million, respectively, leading to this increase in loan servicing income. The Bank experienced a $0.2 million positive valuation adjustment to its mortgage servicing rights asset during the third quarter of 2023 which compared favorably to a $0.5 million negative adjustment in the prior quarter, but unfavorably to a $0.9 million positive adjustment during the prior-year third quarter.

Noninterest expense was $19.6 million in the third quarter of 2023, compared to $19.9 million during the prior quarter and $18.9 million during the third quarter of 2022. Most areas of noninterest expense have increased over the past five quarters as a result of added operational scale from the acquisitions of Denmark and Hometown, which increased the Bank’s total assets by $1.13 billion, or 38.0%, from the end of the second quarter of 2022 to the end of the third quarter of 2023. Expenses directly attributable to these acquisitions have also caused volatility in several noninterest expense areas, most notably personnel, occupancy and outside service fee expenses during the third quarter of 2022 and the first quarter of 2023. Core deposit intangible assets of $15.1 million and $16.5 million created by the Denmark and Hometown acquisitions, respectively, have also created an increase in amortization of intangible assets expense over the last five quarters. Finally, net losses on sales of OREO totaled $0.1 million during the third quarter of 2023 compared to $0.5 million during the prior quarter and no loss during the third quarter of 2022. All losses noted in the current and prior quarter related to operating locations acquired from Hometown and Denmark, as well as one from a previously acquired institution, which were not utilized as operating locations by Bank First. At the start of the second quarter of 2023 Bank First held nine such buildings, but finished the third quarter with only two as a result of these sales.

The current Wisconsin state budget, signed by Governor Evers on July 5, 2023, included a provision offering an income tax exclusion on income earned from commercial loans of $5 million or less, originated for business or agricultural purposes to borrowers who reside or are located in the state of Wisconsin. This exclusion is retroactive to January 1, 2023. As a result of this provision, Bank First reversed $2.4 million in income tax expense which had been recorded during the first two quarters of 2023. Also as a result of this provision, Bank First’s lower anticipated future effective tax rate required an allowance to be made against the Bank’s deferred tax asset, which increased income tax expense by $2.9 million. These two entries netted to a one-time $0.5 million increase to income tax expense for the third quarter of 2023.

Balance Sheet

Total assets were $4.09 billion at September 30, 2023, a $427.1 million increase from December 31, 2022, and a $446.8 million increase from September 30, 2022. The preliminary fair value of assets acquired in the Hometown acquisition during the first quarter of 2023 totaled approximately $614.4 million.

Total loans were $3.36 billion at September 30, 2023, up $416.6 million from December 31, 2022, and up $496.3 million from September 30, 2022. Loans grew 5.0% on an annualized basis during the third quarter of 2023.

Total deposits, nearly all of which remain core deposits, were $3.40 billion at September 30, 2023, up $338.1 million from December 31, 2022, and up $260.1 million from September 30, 2022. As mentioned earlier in this release, noninterest-bearing demand deposits comprised 32.1% of the Bank’s total core deposits at September 30, 2023, compared to 31.1% and 31.3% at December 31 and September 30, 2022, respectively.

Asset Quality

Nonperforming assets at September 30, 2023 remained negligible, totaling $5.2 million compared to $6.7 million and $6.2 million at the end of the fourth and third quarters of 2022, respectively. Nonperforming assets to total assets ended the third quarter of 2023 at 0.13%, down from 0.18% at the end of the fourth and third quarters of 2022. Nonperforming assets at September 30, 2023 included two properties valued at $1.8 million that were previously operating branch locations of acquired institutions which are no longer part of the Bank’s branch network. These properties have all been listed for sale.

Capital Position

Stockholders’ equity totaled $577.3 million at September 30, 2023, an increase of $124.2 million from the end of 2022 and $137.9 million from September 30, 2022. The acquisition of Hometown during the first quarter of 2023 increased total stockholders’ equity by $115.1 million. Bank First’s tangible common equity (non-GAAP) increased by $47.6 million and $63.6 million during the first nine months of 2023 and trailing twelve months, respectively. The Bank’s book value per common share totaled $55.62 at September 30, 2023 compared to $50.22 at December 31, 2022 and $48.67 at September 30, 2022. Tangible book value per common share (non-GAAP) totaled $36.00 at September 30, 2023 compared to $36.14 at December 31, 2022 and $34.34 at September 30, 2022.

Dividend Declaration

Bank First’s Board of Directors approved a quarterly cash dividend of $0.30 per common share, payable on January 10, 2024, to shareholders of record as of December 27, 2023. This dividend represents a 20.0% increase over the dividend declared one year earlier.

Subsequent Transactions

The Bank sold 100% of its member interest in UFS, LLC in a transaction which closed on October 1, 2023. This transaction resulted in proceeds of $52.2 million and a pre-tax gain of $39.3 million which will be realized during the fourth quarter of 2023.

On October 2, 2023, the Bank repaid $11.5 million in subordinated debt owed to three financial institutions. Interest expense related to this debt, each of which carried an interest rate of 9.0%, totaled over $1.0 million annually.

Forward-Looking Statements: Certain statements contained in this press release and in other recent filings may constitute forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. These forward-looking statements include, without limitation, statements relating to the timing, benefits, costs, and synergies of the mergers with Denmark and Hometown, statements relating to our projected growth, anticipated future financial performance, financial condition, credit quality and management’s long-term performance goals, and statements relating to the anticipated effects on our business, financial condition and results of operations from expected developments or events, our business, growth and strategies. These statements can generally be identified by the use of the words and phrases “may,” “will,” “should,” “could,” “would,” “goal,” “plan,” “potential,” “estimate,” “project,” “believe,” “intend,” “anticipate,” “expect,” “target,” “aim,” “predict,” “continue,” “seek,” “projection,” and other variations of such words and phrases and similar expressions.

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.

This communication contains non-GAAP financial measures, such as non-GAAP adjusted net income, non-GAAP adjusted earnings per common share, adjusted earnings return on assets, tangible book value per common share, and tangible common equity to tangible assets. Management believes such measures to be helpful to management, investors and others in understanding Bank First's results of operations or financial position. When non-GAAP financial measures are used, the comparable GAAP financial measures, as well as the reconciliation of the non-GAAP measures to the GAAP financial measures, are provided. See " Non-GAAP Financial Measures" below. The non-GAAP net income measure and related reconciliation provide information useful to investors in understanding the operating performance and trends of Bank First and also aid investors in comparing Bank First's financial performance to the financial performance of peer banks. Management considers non-GAAP financial ratios to be critical metrics with which to analyze and evaluate financial condition and capital strengths. While non-GAAP financial measures are frequently used by stakeholders in the evaluation of a corporation, they have limitations as analytical tools and should not be considered in isolation or as a substitute for analyses of results as reported under GAAP.

Further information regarding Bank First and factors which could affect the forward-looking statements contained herein can be found in Bank First's Annual Report on Form 10-K for the fiscal year ended December 31, 2022, and its other filings with the Securities and Exchange Commission (the “SEC”). Many of these factors are beyond Bank First’s ability to control or predict. If one or more events related to these or other risks or uncertainties materialize, or if the underlying assumptions prove to be incorrect, actual results may differ materially from the forward-looking statements. Accordingly, shareholders and investors should not place undue reliance on any such forward-looking statements. Any forward-looking statement speaks only as of the date of this press release, and Bank First undertakes no obligation to publicly update or review any forward-looking statement, whether as a result of new information, future developments or otherwise, except as required by law. New risks and uncertainties may emerge from time to time, and it is not possible for Bank First to predict their occurrence or how they will affect the company.
