Bank First (BFC) 8-K Regulation FD Disclosure

Exhibit 99.1

To our shareholders, Thus far, 2022 has been an exciting year for Bank First as our dedicated team of bankers continues to deliver exceptional financial results as we grow the Bank through solid organic growth complimented by strategic bank acquisitions. This growth is fueled by our team consistently delivering Bank First’s G.U.E.S.T. experience to each customer we serve. At the bank, we Greet our customers by Using their name, making Eye contact, Smiling and Thanking them for their relationship. In the first six months of 2022, Bank First has grown loans (excluding the impact of Paycheck Protection Program loan activity) by 16.24% on an annualized basis. Kevin LeMahieu, our CFO, and I are often asked by financial analysts and institutional investors for Bank First’s secret to delivering consistently strong growth over the years. By focusing our growth on building and growing banking relationships instead of transactions, and delivering our customers with the G.U.E.S.T. experience, we have developed a very loyal customer base. This is demonstrated by our Net Promoter Score of 84, which means nearly 90% of customers responding to a survey are enthusiastic promoters of Bank First and its products and services. Our reputation of providing exceptional customer service puts Bank First at top of mind for other banks seeking to partner with a larger financial institution. We are proud to announce that we closed on our merger with Denmark Bancshares, Inc. on Friday, August 12, and welcomed their customers to the bank on Monday, August 15. Our acquisition of Denmark State Bank will grow our assets by approximately $690 million and enhance our presence in Manitowoc and Brown counties, and expands our footprint to include Shawano County. On July 26, 2022, we announced our upcoming merger with Hometown Bancorp, Ltd, a $627.6 million bank, headquartered in Fond du Lac, Wisconsin. Hometown is a relationship-focused bank that was built on trust and exceptional customer service. This acquisition will grow our presence in Outagamie and Jefferson counties and introduce Bank First to Fond du Lac, Waushara and Columbia counties. Upon completion of the merger on February 10, 2023 (which is subject to regulatory approval), Tim McFarlane, Hometown’s President and CEO, will be joining Bank First as its President. I will remain the bank’s CEO and together we will work diligently to give our team of bankers the products, services and support they need to continue delivering the G.U.E.S.T. experience to all our current and future customers.

This dividend represents a 13.6% increase over the previous quarter’s dividend, and a 19.0% increase over the dividend declared one year earlier. Bank First elects Molepske as Chairman of the Board, Sachse as Lead Independent Director Bank First Corporation announced the election of Michael B. Molepske as Chairman of the Board of Directors of Bank First Corporation and Bank First effective June 13, 2022. Mr. Molepske assumed the role from Michael G. Ansay, who will be retiring from the board in 2024. To facilitate a smooth transition of leadership to Mr. Molepske, Mr. Ansay stepped down from the role of Chairman with the intention of providing guidance and continuity to the board over the next two years. David R. Sachse has been elected as Lead Independent Director, succeeding Donald R. Brisch, who retired from the Board of Directors on June 13, 2022. The Board of Directors is confident that the industry knowledge, experience, and leadership of all its directors will continue to translate to outstanding customer experience and shareholder return. Brisch and Dempsey retire from the Board of Directors Donald R. Brisch and Michael P. Dempsey, two long-time members of the Board of Directors, retired from the board on June 13, 2022. During his tenure, Brisch has served as Lead Independent Director and participated as a member of every committee. Dempsey became a director of Bank First Corporation and the bank in 2014. He was later named President of the bank in 2015 and served on the bank’s Senior Management Team. With his extensive banking experience, Dempsey provided valuable insight, leadership, creativity, and strength to the Board of Directors. MIKE MOLEPSKE DAVID SACHSE DONALD BRISCH MICHAEL DEMPSEY Total assets for the Company increased by 2.8% to $2.92 billion at March 31, 2022, compared to $2.85 billion at March 31, 2021. Loans grew by $87.8 million, representing a 3.9% increase year-over-year. Loan balances originated under the Small Business Administration’s Paycheck Protection Program (“PPP”) totaled $16.9 million at March 31, 2022 compared to $188.2 million at March 31, 2021. Excluding the impact of PPP loans, other loans at the Company increased by $259.1 million, or 12.7%, year-over-year. Deposits increased by $109.1 million during this same period, or 4.5%. Growth in deposits trailed growth in loans during the previous twelve months. Significant government stimulus was put into the economy during 2020 and early 2021, with limited ways to spend it due to many areas of society being shut down, causing deposits at Bank First as well as most financial institutions to swell. During the latter part of 2021 and the first quarter of 2022 some of this stimulus has begun to leave depository accounts as it is deployed into the economy, stunting the growth in overall deposits at the Company year-over-year. Earnings per share for the quarter ended March 31, 2022, was $1.34. This represents a decrease of 10.1% compared to earnings per share of $1.49 during the first quarter of 2021. Loans originated under PPP added $0.6 million to interest income for the first quarter of 2022, compared to $2.4 million for the first quarter of 2021, a reduction of approximately $0.16 in quarterly earnings per share for the first quarter year-over- year. The decline in retail residential lending mentioned in the next paragraph further reduced first quarter year-over-year earnings per share by $0.20. Net income was $10.2 million for the quarter ended March 31, 2022, compared to $11.5 million during the quarter ended March 31, 2021. Non-interest income totaled $5.2 million for the quarter ended March 31, 2022, down from $6.3 million during the first quarter of 2021. A primary driver for this decrease was a significant slowdown in the retail lending environment after a robust run through 2020 and 2021, leading to gains on sales of mortgage loans to the secondary market of $0.7 million during the first quarter of 2022, compared to $2.8 million during the first quarter of 2021. Non-interest expense totaled $12.7 million for the quarter ended March 31, 2022, up from $12.4 million for the first quarter of 2021. Most areas of non-interest expense experienced modest increases, though overall expenses were well contained considering the inflationary environment that developed during the end of 2021 and start of 2022. Outside service fees increased by $0.4 million, or 55.2%, during the first quarter of 2022 compared to the first quarter of 2021, due primarily to $0.5 million in expenses related to the pending acquisition of Denmark Bancshares, Inc. Total shareholders’ equity increased by 4.9% to $318.3 million at March 31, 2022, compared to $303.4 million at March 31, 2021. Equity increased due to strong earnings which were offset by dividends totaling $8.8 million, common share repurchases totaling $12.9 million, and a decline in the fair value of our available for sale securities portfolio (due to interest rate movements) of $9.1 million over the twelve months from the end of the first quarter of 2021 to the end of the first quarter of 2022.
