FOR IMMEDIATE RELEASE

Bank First Announces Net Income for the Fourth Quarter of 2020

MANITOWOC, Wis, January 19, 2021 -- Bank First Corporation (NASDAQ: BFC) (“Bank First” or the “Bank”), the holding company for Bank First, N.A., reported net income of $11.5 million, or $1.49 per share, for the fourth quarter of 2020, compared with net income of $7.5 million, or $1.05 per share, for the respective prior-year period. For the year ended December 31, 2020, Bank First earned $38.0 million, or $5.07 per share, compared to $26.7 million, or $3.91 per share for the year ended December 31, 2019.

Operating Results

Net interest income (“NII”) during the fourth quarter of 2020 was $24.5 million, up $1.5 million from the previous quarter and up $5.7 million from the fourth quarter of 2019. NII for the year ended December 31, 2020 was $86.8 million, up from $69.7 million during the prior year.

NII related to purchase accounting entries, resulting from Bank First’s purchases of Waupaca Bancorporation, Inc. (“Waupaca”) during the fourth quarter of 2017, Partnership Community Bancshares, Inc. (“Partnership”) during the third quarter of 2019, and Tomah Bancshares, Inc. (“Tomah”) during the second quarter of 2020 increased net income (after tax) during the fourth quarter of 2020 by $0.5 million, or $0.07 per share, compared to $1.1 million, or $0.16 per share, for the fourth quarter of 2019. For the years ended December 31, 2020 and 2019, the impact of these purchase accounting entries increased net income (after tax) by $3.1 million, or $0.41 per share, and $5.1 million, or $0.74 per share, respectively.

Net interest margin (“NIM”) was 4.01% for the fourth quarter of 2020, compared to 3.85% for the fourth quarter of 2019. The aforementioned purchase accounting entries added 0.12% and 0.30% to NIM for each of these periods, respectively. NIM was 3.84% for the year ended December 31, 2020, including 0.18% from the impact of purchase accounting entries, compared to 3.95%, including 0.37% from the impact of purchase accounting entries, for the year ended December 31, 2019.

Bank First recorded a provision for loan losses of $1.7 million during the fourth quarter of 2020, compared to $1.1 million during the fourth quarter of 2019. Provision expense was $7.1 million for the year ended December 31, 2020, compared to $5.3 million for the prior year. Net loan charge-offs totaled $0.3 million during the fourth quarter of 2020 and $0.9 million for the full year ended December 31, 2020. Management continues to monitor the stress on the overall economy caused by the COVID-19 pandemic, as well as specific impacts on Bank First customers. These factors will guide assessments of the adequacy of the allowance for loan losses in future quarters. As discussed later in this release, these impacts were minimal through the end of 2020.

Noninterest income was $6.7 million for the fourth quarter of 2020, compared to $3.2 million for the fourth quarter of 2019. During December 2020 Bank First sold its Chetek, Wisconsin branch location to another institution, resulting in a gain on sale of $1.7 million. Expenses related to this sale totaled $0.3 million during the quarter, and are included in noninterest expense. As in other quarters during 2020, strong activity in sales of mortgage loans to the secondary market led to a large year-over-year increase in net gains on these sales, totaling $2.2 million during the fourth quarter of 2020, compared to $0.6 million during the fourth quarter of 2019. Service charges earned by the Bank increased from $1.1 million during the fourth quarter of 2019 to $1.6 million during the fourth quarter of 2020, continuing to reflect the increased scale resulting from the Bank’s recent acquisitions. Income from Bank First’s ownership in Ansay & Associates, LLC, totaled $0.2 million during the fourth quarter of 2020, comparing favorably to $0.1 million during the prior-year fourth quarter, but declining from the first three quarters of 2020. The agency’s top three carriers had negative claim trends during 2020 that had a corresponding negative impact on the agency’s projected contingency income for the year, leading to an unfavorable adjustment in the fourth quarter. Finally, servicing fee income was negatively impacted during the fourth quarter of 2020 by an adjustment to the value of mortgage servicing rights on Bank First’s balance sheet totaling $0.4 million.

Noninterest expense was $14.0 million for the fourth quarter of 2020, compared to $12.2 million during the previous quarter and $11.2 million during the fourth quarter of 2019. Personnel expense totaled $7.6 million during the fourth quarter of 2020, compared to $6.6 million during the prior quarter, and $5.9 million during the prior year fourth quarter. Personnel expenses during the fourth quarter of 2020 included approximately $0.7 million in one-time bonus accruals and payments for employees who have incentive compensation tied to Bank profitability goals. These adjustments were necessary based on the Bank’s strong financial results for 2020. Occupancy, equipment and office expenses were elevated during the fourth quarter of 2020 as the Bank took advantage of branch closures to complete large scale remodel projects in several of our branch locations. Data processing expense continued to be elevated during the fourth quarter of 2020 due to higher “per-account” charges as a result of additional customer relationships from the acquisitions of Partnership and Tomah, as well as accounts and relationships added during the origination of Paycheck Protection Program (“PPP”) loans. In addition to these items, a one-time charge to data processing expense of $0.1 million was incurred as a result of booking PPP loans earlier in the year. As mentioned previously in this release, costs associated with the sale of the Chetek location marginally increased personnel, data processing, outside service fee and amortization expense.

Balance Sheet

Total assets were $2.72 billion at December 31, 2020, up $507.8 million from December 31, 2019. Total loans were $2.19 billion at December 31, 2020, up $455.1 million from December 31, 2019. Purchased loan balances included in the acquisition of Tomah during May 2020 totaled $111.9 million. Of the $279.6 million in PPP loans originated by Bank First during the second and third quarters of 2020, $171.2 million remained at year-end. Excluding the impact of acquired and PPP loans, Bank First experienced 9.5% loan growth during 2020, including annualized growth of 22.3% during the fourth quarter, as it gained market share in its communities by capitalizing on new relationships formed through its ability to assist businesses during the first half of 2020 when their former financial institutions were unresponsive. Total deposits, nearly all of which remain core deposits, were $2.32 billion at December 31, 2020, up $477.7 million from December 31, 2019. Deposit balances assumed during the acquisition of Tomah in May 2020 totaled $171.1 million. Noninterest-bearing demand deposits increased $242.8 million during 2020, comprising 31.2% of total deposits at December 31, 2020 compared to 26.2% one year earlier.

Asset Quality

Nonperforming assets at December 31, 2020 totaled $14.0 million, down from $20.8 million at the end of the prior quarter, but up from $11.5 million at the end of the fourth quarter of 2019. Nonperforming assets to total assets ended the fourth quarter of 2020 at 0.52%, down from 0.79% at the end of the prior quarter, and matching the level at the end of fourth quarter of 2019. This quarter-over-quarter improvement continues the trend of improving asset quality that started during the third quarter of 2020. After ending the second quarter of 2020 at $23.0 million, nonaccrual loans declined to $10.8 million at year end. As noted in Bank First’s third quarter 2020 earnings update, the remaining balance of nonaccrual loans relates primarily to one commercial real estate loan in northern Wisconsin totaling $7.2 million which was moved to nonaccrual status in June 2020. While payments have remained current on this loan through year-end, the move to nonaccrual status was deemed prudent by management due to the loss of a significant tenant in the underlying commercial property.

Since the inception of the COVID-19 pandemic, Bank First has proactively worked with its customers to ensure that, consistent with the guidance of the Coronavirus Aid, Relief, and Economic Security (“CARES”) Act, it is partnering with them to navigate the economic shocks resulting from legislative actions intended to slow the spread of the virus. As part of this process, payment deferrals were granted to over 625 Bank First customers on loans totaling over $271.5 million. At December 31, 2020, Bank First had less than $20.0 million remaining that were in some stage of deferral in coordination with the CARES Act.

Capital Position

Stockholders’ equity totaled $294.9 million at December 31, 2020, an increase of $64.6 million from the end of 2019. The acquisition of Tomah during May 2020 added $29.4 million to capital. Bank First’s repurchase of 74,462 shares at an average price of $58.65 during 2020 reduced capital by $4.4 million. Finally, continued strong earnings offset by dividends totaling $6.1 million during the year ended December 31, 2020, led to a majority of the remaining increase in capital year-to-date. Tangible book value per share of Bank First’s common stock saw an annualized increase of 16.9% during the fourth quarter of 2020, and an increase of 18.6% for the full year of 2020.

Dividend Declaration

Bank First’s Board of Directors approved a quarterly cash dividend of $0.21 per common share, payable on April 7, 2021, to shareholders of record as of March 24, 2021.
