    Officers of the Board of Directors (2025) Chairman: Michael B. Molepske Chief Executive Officer: Michael B. Molepske Chief Financial Officer: Kevin M. LeMahieu President: Timothy J. McFarlane Chief Legal Counsel: Kelly M. Dvorak Chief Lending Officer: Jason V. Krepline During the previous ten (10) years, no director, person nominated to become a director, or executive officer of the Company was the subject of any legal proceeding that is material to an evaluation of the ability or integrity of any such person. CORPORATE GOVERNANCE Overview We are committed to sound corporate governance principles, which are essential to running our business efficiently and maintaining our integrity in the marketplace. We understand that corporate governance practices change and evolve, and we seek to adopt and use practices that we believe will be of value to our shareholders and will positively aid in the governance of the Company. We will continue to monitor emerging developments in corporate governance and update our policies and procedures when required or when our Board of Directors determines that it would benefit us and our shareholders. Board Leadership Structure The Company is committed to strong Board leadership. Our governance framework allows the Board to select the appropriate leadership structure for the Company. In making leadership structure determinations, the Board considers many factors, including the specific needs of the business and what is in the best interests of the Company’s shareholders. In accordance with the Company’s Bylaws, our Board of Directors elects our Chairman and CEO, and these positions may be held by the same person or different individuals. Currently, the roles of Chairman of the Board and CEO are both held by Michael B. Molepske. The Board believes that combining these two roles provides more consistent communication and coordination throughout the organization, which results in a more effective and efficient implementation of corporate strategy and is vital in unifying the Company’s strategy behind a single vision. Since one individual serves as our Chairman of the Board and CEO, the Board also nominated Mary-Kay H. Bourbulas as the Company’s Lead Independent Director for 2025. The Chairman of the Board is responsible for chairing Board meetings and meetings of shareholders, setting the agendas for Board meetings in consultation with the Lead Independent Director, and providing information to Board members in advance of meetings and between meetings. The Lead Independent Director is responsible for: • Working with the Chairman of the Board, Board and Corporate Secretary to set the agenda for Board meetings; • Calling regularly scheduled executive sessions of the independent and non-management directors; • Developing the agenda for and chairing executive sessions of the independent directors; • Acting as liaison between the independent directors and the Chairman of the Board on matters raised in such executive sessions; • Chairing Board meetings when the Chairman of the Board is not in attendance; • Attending meetings of the committees of the Board, as necessary or at their discretion, and communicating regularly with the chairs of the principal standing committees of the Board; • Working with the Chairman of the Board to ensure the conduct of Board meetings provides adequate time for serious discussion of appropriate issues and that appropriate information is made available to Board members on a timely basis; • Performing such other duties as may be requested from time to time by the Board, the independent directors, or the Chairman of the Board; and • Being available, upon request, for consultation and direct communication with major shareholders. After careful consideration, the Board has determined that the Company’s current Board structure is the most appropriate leadership structure for the Company and its shareholders. From time to time, the Board leadership structure will be reevaluated to ensure it remains the most effective approach in serving the Company’s goals. Executive Sessions Our Bylaws provide for executive sessions of our non-management and independent directors, giving them a significant voice. Our Board believes this is a crucial governance practice, enabling the Board to discuss matters without management present. Our independent directors meet in regularly scheduled executive sessions at least twice annually and at other times as may be deemed appropriate by the Company’s independent directors. Our Lead Independent Director presides over all executive sessions of the independent and non-management directors and sets the agenda for such sessions. Any independent director may call an executive session of independent directors at any time. The independent directors met at least twice in an executive session in 2025. Role of Board in the Oversight of Risk The Board has the ultimate authority and responsibility for overseeing our risk management. The Board monitors, reviews, and reacts to material enterprise risks that management identifies. The Board receives specific reports from management on financial, credit, liquidity, cybersecurity, artificial intelligence, interest rate, capital, operational, legal compliance, and reputation risks, as well as the degree of exposure to those risks. The Board helps ensure that management is appropriately focused on risk by, among other things, reviewing and discussing the performance of senior management and business line leaders. Board committees are responsible for risk oversight in specific areas. The Audit Committee manages financial, accounting, and internal control risk management policies and also oversees the risk and compliance programs. The Compensation Committee assesses and monitors risks in our compensation program and determines the compensation for directors and named executive officers. The Governance and Nominating Committee oversees the nomination process and evaluation of the Board and is responsible for reviewing the Company’s policies and procedures. The Enterprise Risk Management Committee is primarily responsible for managing risk across the Company consistent with the Company’s strategic goals and objectives, risk culture, and risk appetite. The Asset and Liability Management Committee monitors our interest rate risk to structure our asset-liability composition to maximize net interest income while minimizing the adverse impact of changes in interest rates on net interest income and capital. As discussed more fully below, the Information Technology Committee assesses, identifies, and manages material risks associated with cybersecurity threats. Cybersecurity Risk Management and Strategy Assessing, identifying and managing material risks from cybersecurity threats is critical for maintaining the security of the Company’s data and information systems, and is integrated into our enterprise risk management systems and processes. Over the past few years, the Board has also spent significant time overseeing management’s efforts to address evolving and growing cyber- and technology-related risks and opportunities, including, most recently, the growth in the use and implementation of generative artificial intelligence. The Bank’s approach to cybersecurity risk management and strategy is based on the Cyber Risk Institute (“CRI”) Profile, which is a comprehensive, industry-standard cybersecurity framework tailored for the financial sector to assess risk and ensure regulatory compliance. The CRI incorporates cybersecurity-related principles from the National Institute of Standards and Technology (“NIST”) Cybersecurity Framework, regulatory guidance, and concepts from other industry standards.

  18. Directors Whose Terms Expire in 2028

    The CRI consists of two parts: Impact tiering, which is used to identify the Bank’s cybersecurity maturity expectations; and the risk assessment. Completion of both parts of the CRI allows management and the Board to evaluate whether the Company’s cybersecurity risk and preparedness are aligned. The CRI impact tiering is a self-assessment, prompting questions to customize the profile assessment, based on the institution’s risk and activities. The risk assessment portion of the CRI contains diagnostic statements grouped by function, category and subcategory. The risk assessment indicates the applicability of each diagnostic statement to each impact tier level. Each statement is given an assessment rating with supporting rationale and evidence provided to justify the rating given. Functions in the risk assessment portion include: (i) Govern; (ii) Identify; (iii) Protect; (iv) Detect; (v) Respond; (vi) Recover; and (vii) Extend. The Information Security Officer (“ISO”) and the Company’s management-level Information Technology Committee conduct and review the CRI annually to identify changes to the Company’s inherent impact tier and risk profile; when new threats arise or when considering changes to the business strategy, such as expanding operations, offering new products and services, or entering into new third-party relationships that support critical activities. Consequently, management can determine whether additional risk management practices or controls are needed to maintain or augment the Company’s cybersecurity maturity. In an effort to continually share threat intelligence and increase awareness of cybersecurity trends, the Company has also implemented a Cybersecurity Education and Awareness Program. Among others, this program includes the following components: • Mandatory annual cybersecurity employee training for all employees; • Training specifically targeted to Senior Management and Information Technology staff; • Monthly cybersecurity phishing simulation campaigns; • Quarterly review of emerging security trends by the management-level Risk Management Committee; • Mandatory annual cybersecurity Board training; and • Periodic communication to employees highlighting internal control requirements and information about common threats or fraud schemes. The Company retains external consultants to assist in the development and monitoring processes for assessing, identifying, and managing potential cybersecurity threats. The Company engages third-party service providers to conduct evaluations of security controls, including through penetration testing and independent assessments, and to provide consulting regarding recommended practices to address new challenges. The Company also requires third-party service providers to report cybersecurity incidents so the Bank can assess their impact. As part of the Bank’s vendor management process, the Bank conducts information security due diligence of third parties with whom the Bank will interact, including risk profiling and classification. The Company’s vendor risk management program includes regular reviews and oversight of all service providers in accordance with a risk profile classification. To date, we have not experienced a cybersecurity incident that has, or is reasonably likely to have, materially impacted our business strategy, results of operations, or financial condition. Board and Management Governance The Board recognizes the importance of maintaining the trust and confidence of our customers, employees, and shareholders, including the risks associated with cybersecurity threats. The Board’s responsibilities for cybersecurity risk management and strategy, some of which are delegated to the Audit Committee, include the following: • Engaging management in establishing the Bank’s vision, risk tolerance, and overall strategic direction; Approving plans to ensure the use of the CRI; Reviewing management’s analysis of the CRI results, inclusive of any reviews or opinions on the results issued by independent risk management or internal audit functions regarding those results; • Reviewing management’s determination of whether the Bank’s cybersecurity preparedness is aligned with its risks; • Reviewing and approving plans to address and enhance any risk management procedures or controls; and • Reviewing the results of management’s ongoing monitoring of the Bank’s exposure to and preparedness for cyber threats. The Board’s oversight of cybersecurity risk is supported by our ISO, who reports directly to the Audit Committee and to the Chief Legal Counsel and shares a co-sourced relationship with a third-party consultant. The ISO attends Audit Committee meetings and provides cybersecurity updates to the Audit Committee. The ISO also provides annual risk assessments and reports regarding the information security program to the full Board. Cybersecurity risk metrics and program updates are reported to management and the Audit Committee on a regular cadence, with periodic director education sessions supporting oversight. The Audit Committee is also involved in oversight of potentially significant cybersecurity incidents, which are evaluated for materiality without unreasonable delay, consistent with SEC rules. The ISO has been with Bank First for over 12 years in various operational and administrative roles. For the past six years, he has served as the Bank’s VP-Enterprise Risk Manager, and as ISO for the past three years. In 2022, he earned the Certified Banking Security Manager certification from SBS Cybersecurity. The ISO works closely with the Chief Information Officer to ensure that the Bank’s cybersecurity controls are in line with established internal culture, Board expectations and risk appetite, and all regulatory requirements. The ISO’s responsibilities include the following: • Developing a plan to conduct and complete the CRI on an annual basis; • Working with the Chief Information Officer to evaluate the results of the CRI; • Leading employee efforts during the CRI to facilitate timely responses from across the Bank; • Setting the target state of cybersecurity preparedness that best aligns to the Board of Directors’ approved risk tolerance; • Reviewing, approving, and supporting plans to address risk management and enhancing controls; • Analyzing and presenting the results of the CRI to the full Board of Directors; • Providing periodic cybersecurity updates to the full Board of Directors; • Overseeing the performance of ongoing monitoring to address evolving areas of cybersecurity risk; • Overseeing frequent testing/auditing activities, cybersecurity risk assessments, vulnerability scanning, penetration testing, monitoring of external threat intelligence and supplier risk sources, and 24/7 incident monitoring to inform our understanding of the cybersecurity risk landscape; • Overseeing the Bank’s cybersecurity preparedness. Board Self-Evaluation The Board conducts an annual evaluation process, utilizing an evaluation platform developed by an independent third party. Each director evaluates their own performance, as well as the performance of their fellow directors. The Governance and Nominating Committee reviews the evaluations, and the aggregated results are shared and discussed by the Board as a whole. The evaluation process improves the overall effectiveness of the Board by identifying its strengths, as well as areas for which additional training may be needed. In 2025, each committee of the Board also engaged in a self-assessment, which evaluated each committee’s performance and identified areas of improvement. Director Independence

  19. Directors Whose Terms Expire in 2028

    The Board has evaluated the independence of its directors in accordance with NASDAQ and SEC rules regulations. Our corporate governance guidelines and principles, as well as the NASDAQ rules require that a majority of the Board be composed of directors who meet the requirements for independence established by these standards. Based on those standards, the Board has determined that Ms. Bourbulas, Ms. Davis, Mr. Gregorski, Mr. Johnson, Mr. Maples, Mr. McConeghy, Mr. Sprang, Mr. Stayer-Suprick and Mr. Van Sistine do not have relationships that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director, and that each of those directors is independent as that term is defined by NASDAQ and SEC rules. The Board has determined that Mr. Eldred, Mr. McFarlane and Mr. Molepske do have relationships that may give the appearance of interfering with the exercise of independent judgment in carrying out the responsibilities of a director, and that none of them are independent. Mr. Eldred is not independent because of his current consulting arrangement with the Company. Mr. McFarlane and Mr. Molepske are not independent because they serve as executive officers of both the Company and the Bank. The Board has further determined that each director who serves on the Audit, Compensation, and Governance and Nominating Committees satisfies the independence requirements for such committees in accordance with the NASDAQ and SEC rules. In 2025, the Board consisted of ten (10) independent directors and two (2) non-independent directors. Director Qualifications We believe our directors should have the highest professional and personal ethics and values consistent with our longstanding values and standards. They should have broad experience at the policy-making level in business, government, or civic organizations. They should be committed to enhancing shareholder value. They should have sufficient time to carry out their duties and to provide insight and practical wisdom based on their own unique experience. Each director must represent the interests of all shareholders. When considering potential director candidates, our Board of Directors also evaluates the candidate’s independence, character, judgment, diversity, age, skills, financial literacy, and experience in the context of the Company’s needs and those of the Board of Directors. Our Board of Directors’ priority in selecting board members is identifying individuals who will further the interests of our shareholders through their record of professional and personal experiences and expertise relevant to our growth strategy. The following matrix depicts the diversity of experience of our Board of Directors.

The Company is focused on operating the business in a responsible and financially sustainable manner, as it believes it better serves its communities while also having a positive effect on operating expenses. The Company also believes that it is important for its clients to reflect the values behind how it does business, which is why it endeavors to steward its capital and resources toward investments that drive value, and responsible and sustainable business practices. Sustainability Bank First takes pride in its initiatives to reduce our environmental footprint. We have committed significant resources to reducing our carbon footprint in all our branches by using energy-efficient building practices in our newly constructed branches and by remodeling our existing branches to increase energy efficiency. We consistently use low-E energy efficient windows, LED lighting, high-efficiency HVAC systems, recycled building materials, office furniture made from recycled materials, and low-flow bathroom fixtures to conserve water. Our Howard branch features a roof-mounted photovoltaic system, which has provided about 32% of the building’s energy demand over the past year. Our Fond du Lac branch has been constructed to accommodate a similar system. Our facilities are constructed using wood frames, a renewable resource that sequesters carbon. Locally sourced materials, such as Wisconsin limestone, are used to minimize the environmental impact of transportation in the supply chain. Our operations are also largely paperless, reducing our reliance on trees and paper products. We maximize natural daylight in our new buildings, reducing the need to use electric lighting in most spaces. We utilize switches and occupancy sensors to ensure that energy is only used as needed. When possible, we also link our buildings to bike paths and sidewalks, which benefits both our employees and the community. We have a dedicated team of employees committed to creating solutions and implementing environmentally friendly procedures. Through their efforts, we have taken many actions to reduce our footprint, including the following: • Using recycled facility products and donating furniture and other supplies when remodeling or constructing new offices. • Defaulting the printers to print from one-sided to two-sided. • Reducing paper consumption by utilizing iPads for meeting materials. The Bank assisted employees in this initiative by reimbursing individuals 50% of the cost of a new iPad. • Rewarding customers for using e-statements versus paper statements. • Installing water bottle filling units in the branches and providing each employee with a new eco-friendly water bottle to reduce bottled water consumption. • Providing paper-shredding days for our customers. • Continuously evaluating our operational workflows to identify opportunities for digitization. Community Building and Social Responsibility “Bank First is a relationship-based bank focused on providing innovative solutions that are value driven to the communities we serve.” This is our promise to our employees, customers, communities, and shareholders. An integral part of this promise is community involvement. Our employees take great pride in serving our communities through volunteering, charitable contributions, education scholarships, and community development initiatives. In 2025, Bank First employees volunteered over 8,670 hours to our surrounding communities. Our culture fosters curiosity, creativity, and responsiveness, while embracing individual differences and upholding the highest ethical standards. We support and encourage employees to develop their careers. They are empowered with the tools to be successful and are held accountable for the results they deliver to our customers and shareholders. Our talent acquisition team collaborates with department leaders to source and deliver a well-rounded slate of qualified candidates to support our organization’s growth. As of December 31, 2025, Bank First had approximately 380 full-time equivalent employees. Approximately 73% of our employees identified themselves as female, and 6% identified themselves as people of color. Women represent 17% of our Board of Directors and 36% of our Senior Management team. Our approach to talent acquisition, development, and retention emphasizes rewarding merit and achievement while supporting the growth and advancement of skilled talent across the Bank. We believe our workforce stability and employee engagement support the consistent delivery of high-quality service to our customers and communities. We believe our employees are our greatest asset and that our future success depends on our ability to attract, retain, and develop employees. Bank First’s mission is to help employees grow both personally and within their roles by creating employee-centric development plans and giving people the autonomy to succeed while holding them accountable to deliver results. Development plans are focused on career growth, personal development, training, mentoring, and community involvement. Employees are encouraged to further enhance their skills and seek additional training if desired. Bank First also promotes leadership training for its staff and provides tuition reimbursement for those looking to further their education. We believe Bank First’s development plan identifies employee strengths and determines where their skills and expertise can be best applied within the organization. Each year, employees are required to complete a thorough self-evaluation where they can address any issues or concerns they may have with their current position. After self-evaluation, a formal review is scheduled between the supervisor and the subordinate. Employees are encouraged to continually raise their hands and let their supervisor know if there is a role in which they would be better suited. Employees can address these concerns at any time throughout the year — not just at review time. In addition, we have a strong internal hiring process. The Bank posts open positions internally first to allow employees to take on a new role or develop themselves within a different department of the bank. We help cultivate employees’ talent by providing internal mentoring and paying for further education and training opportunities that are most relevant to their career goals. Our Board of Directors and Senior Management team truly believe in celebrating the success of our employees, whether they achieve success within the organization or in a role outside the organization that utilizes their talents and helps them grow. We take pride in our current and former employees’ success and will provide the resources to help people grow, whether their long-term plans are to stay with the organization or leave for a role more appropriate to their goals. As part of our effort to attract and retain employees, we offer a broad range of benefits, including health, dental and vision insurance, life and disability insurance, cell phone and health club reimbursement, employee assistance program, educational tuition reimbursement, annual clothing allowance, employee referral program, 401(k) retirement plan, flex spending cafeteria plan, and generous paid time off. We believe our compensation package and benefits are competitive with others in the industry. Bank First is a 6-time award winner of the “Best Banks to Work For” by American Banker.

The Compensation Committee reviews the compensation paid to non-employee directors and executive officers. Directors’ compensation includes annual retainer fees, chair fees, and long-term stock grants (equity ownership). Since the Company’s directors represent the shareholders, we feel they should also be shareholders of the Company. Including equity as part of the annual director compensation package helps ensure that the Company’s directors have a vested interest in its success.

    All directors, executive officers, and members of Senior Management are subject to a share ownership requirement. Upon initial election to the Board, all directors must own at least 1,000 shares of Company common stock. Between the initial election to the Board and the fifth anniversary thereof, all directors must own at least 3,000 shares. The CEO and President must own a minimum of 5,000 shares upon accepting the role of CEO or President and must increase their ownership to at least 15,000 shares by their fifth anniversary. Members of Senior Management, including executive officers, do not have an initial minimum stock ownership requirement but must own a minimum of one and one-half times (1.5x) their base salary in Company stock within five years. All of our directors, executive officers, and Senior Management members complied with our stock ownership policy in the 2025 fiscal year. The Compensation Committee evaluates the competitiveness of director compensation on an ongoing basis. It makes pay recommendations to the full Board for approval at least annually, utilizing data from compensation studies, surveys, and proxy disclosures of peer financial institutions, among other information. At least every three years, a compensation analysis is completed by a third-party independent consultant specializing in executive and board compensation. The last compensation study was conducted by Pearl Meyer in 2023. Upon reviewing the study results, it was determined that director compensation be adjusted in 2023 to better reflect the Company’s desired market positioning. As such, the annual cash retainer was increased from $10,000 to $25,000, and chair fees were increased to $15,000 annually. The annual stock compensation was unchanged at $55,000, and the Lead Independent Director and Board Chair fee remained at $25,000 annually. No changes were made to director compensation in 2025.

COMPENSATION DISCUSSION AND ANALYSIS This Compensation Discussion and Analysis is intended to provide information we believe will help you understand our executive compensation program and decisions as they relate to 2025 compensation for our CEO, Chief Financial Officer, and other named executive officers (“NEOs”) as disclosed in the Summary Compensation Table. Executive Compensation Components We compensate our NEOs through a mix of: • base salary; • performance-based annual cash incentives; • performance-based long-term equity incentive compensation (awarded in the form of restricted stock with a three-year ratable vesting period); and • other benefits and perquisites. We believe that the current mix and value of these compensation elements provide our NEOs with total annual compensation that is reasonable and competitive compared to our peers, appropriately reflects the Bank’s performance, and rewards our NEOs for their performance. Executive Compensation Philosophy The Company’s executive compensation philosophy is intended to provide a total compensation package that is competitive with market practices while varying awards to recognize Company and individual performance. Our compensation program is designed to be performance-based, offering the opportunity to earn higher compensation (via our annual cash and long-term incentive plans) if performance warrants. The objective is to provide competitive pay for achieving performance goals consistent with the Company’s business objectives and its performance relative to that of other financial institutions. The Company’s philosophy is that actual compensation should exceed market when superior performance is achieved and be lower than market when performance falls below expectations. Compensation Program Best Practices Below, we summarize our executive compensation program’s best practices.

  31. Directors Whose Terms Expire in 2028

    | What We Do | What We Don’t Do | | Pay for Performance: We only pay incentives between the target and maximum levels when performance expectations are met or exceeded. | No Excessive Perquisites: We do not provide our NEOs with perquisites not offered to other similarly situated employees. | | Multi-Year Vesting: The multi-year vesting of restricted stock awards helps attract and retain key officers and creates ownership. | No Short Sales or Hedging: Our insider trading policy prohibits the short sale and hedging of Company stock. | | Independent Compensation Consultant: We retain an independent compensation consultant at least every three years to ensure our compensation plans remain competitive. | No Single-Trigger Change in Control Provisions: Our change-in-control agreements require both a change in control of the Company and a subsequent termination of the NEO’s employment to qualify for a change-in-control payment. | | Require Stock Ownership: Our NEOs and directors are required to own Company stock to align their interests with those of shareholders. | No Tax Gross-Ups: We do not provide tax gross-ups in our compensation plans for our NEOs. | | Metrics and Triggers: We ensure that credit quality and regulatory standing metrics and triggers are met before any bonuses are paid. | No Discretionary Bonuses: No discretionary bonuses are paid to NEOs outside the approved compensation program and schedule. |

  32. Material Components of our Compensation Program

    | Compensation Program Component | Rationale | | Peer Group /Industry Surveys | A comparator peer group of public banks with similar financial performance is used to assess our executive and board compensation packages. The peer group allows us to compare our executive and board compensation programs to competitive market practices. Additionally, we utilize banking industry-specific survey data to supplement our peer group assessment of executive and board of director pay. | | Base Salary | While the Bank considers other factors in determining total compensation, base salaries, which have a more immediate impact, must be competitive to attract and retain talent. To reward and retain its top talent, the Bank’s philosophy is for salaries to be based on an individual’s experience and competencies in their role. | | Annual Cash Incentive Plan | The Bank’s annual performance-based bonus program is based on the Bank’s and the executive’s performance in the prior year. Bonuses are calculated as a percentage of salary, with payout opportunity levels established at target and maximum percentages. The program requires the NEO to meet or exceed annual performance targets, such as return on assets, wholesale funding reliance, and earnings per share, as determined and approved by the Compensation Committee each year. Established “trigger” criteria focusing on credit quality and regulatory standing must be met before any bonuses are paid. The payout opportunity levels are determined and approved by the Compensation Committee. | | Long-Term Incentive Plan | The purpose of the Long-Term Incentive/Equity Plan is to provide financial incentives for selected employees of the Company, thereby promoting long-term growth and financial success by attracting and retaining employees of outstanding ability, strengthening the Company’s capacity to develop, maintain, and direct a competent management team, provide an effective means for selected employees to acquire and retain ownership of Company stock, motivate employees to achieve long-range performance goals and objectives, and provide incentive compensation opportunities competitive with those of peers. The Company provides long-term incentives in the form of restricted common stock with a three-year ratable vesting schedule to encourage retention and ownership. | | Other Benefits and Perquisites | Generally, our NEOs participate in the same benefit plans designed for all our full-time employees. We provide our NEOs with a limited number of perquisites that are reasonable and consistent with our overall compensation program enabling us to better attract and retain qualified executives. |

  33. 2023 Compensation Analysis

    2023 Compensation Analysis The Company engaged Pearl Meyer in 2023 to conduct a compensation analysis of the Company’s Board of Directors, executive leadership, and senior leadership. Pearl Meyer is a leading advisor to boards of directors and leadership teams in the area of executive compensation consulting and leadership development. The purpose of the Pearl Meyer engagement was to review the competitive positioning of executive and senior leadership compensation compared to the external market, to provide a market-based framework for proactively managing compensation, and to serve as a basis for discussing potential pay decisions and/or changes to the current compensation structure. The analysis included the selection of the Company’s peer group, as outlined in the table below, and an assessment of the Company’s compensation components compared to survey and peer group proxy data. The analysis found that overall, the Company’s executive pay levels were generally within a market-competitive range (defined as +/- 15% of the peer group median) on salaries, cash compensation (salary + bonus), and direct compensation (cash compensation + three-year average of equity grants). The assessment also found that the Company’s award opportunity levels under the short and long-term incentive plans are competitive compared to our peer group and industry practices. The Compensation Committee and executive management utilized this report to assist with compensation decisions during 2025 but did not rely on it exclusively.

    Peer Group The peer group developed by the Company in conjunction with Pearl Meyer consists of the twenty (20) banks listed below. The peer group was selected based on national, publicly traded banks (excluding those on the coasts) and their 2022 year-end asset size. Additionally, we selected financial performance criteria of ROAA greater than or equal to 1.00% as of 2022 year-end, and three-year total return at the time the peer group was compiled of greater than or equal to 10.0%. We also excluded OTC exchange-traded banks. When the peer group was compiled, the peer banks were between $3 billion and $8 billion in asset size. As of December 31, 2023, the Company’s assets were approximately $4.2 billion.

  36. Annual Cash Incentive Plan

    Annual Cash Incentive Plan We pay annual cash incentive/bonus awards to our NEOs if performance warrants such awards. Annual incentive awards and bonuses are intended to recognize and reward NEOs who contribute significantly to our performance for the year. The Compensation Committee determines whether such bonuses will be paid for any year, and the amount of any bonus paid is based upon annually established formulas and specific performance measures. In 2025, the Company used a performance-based cash incentive plan designed to align executive pay with performance, drive the Company’s strategic goals, and deliver superior financial results. The Plan is designed to achieve the following goals and objectives: • Recognize and reward the achievement of the Bank’s annual goals which are critical to driving our long-term strategy. • Motivate and reward superior performance. • Attract and retain the talent needed for the Bank’s success. • Be competitive with the market. • Encourage teamwork and collaboration through shared goals. • Ensure incentives support sound risk management practices.

  37. 2025 Annual Cash Incentive Plan — Earning Opportunities

    2025 Annual Cash Incentive Plan — Earning Opportunities Below, we detail the 2025 earning opportunities as a percentage of salary for the NEOs under the performance-based Annual Cash Incentive Plan. As mentioned previously, the 2023 independent compensation consulting assessment found that the Company’s award opportunity levels under both our short and long-term incentive plans were overall competitive compared to our peer group and industry practices.

  39. 2025 Annual Cash Incentive Plan — Earning Opportunities

    (a) Bank First’s annual compensation cycle begins on March 15 of each year. The 2025 Actual Cash Incentive as a Percentage of Salary is calculated based on actual salaries earned during the year, including the NEOs’ 2024 salary paid from January 1 to March 15, 2025, and their new 2025 salary paid from March 16 to December 31, 2025. For purposes of the table above, we illustrate the actual award as a percentage of salary using the award earned in relation to the target and maximum award earning potential as a percentage of salary. Actual amounts paid are reflected in the Non-Equity Incentive column of the Summary Compensation table.

  40. 2025 Annual Cash Incentive Plan — Metric Performance Calculation and Actual Performance Results

    2025 Annual Cash Incentive Plan — Metric Performance Calculation and Actual Performance Results The annual cash incentive plan is based on achieving specific performance measures. The Bank sets target and maximum criteria for each goal and links them to payout levels. The Bank uses a proportional approach to determine incentive payouts when performance goal results fall between target and maximum. If performance is below a threshold level, then no payment is made for the applicable goal. The 2025 annual cash incentive plan was based on achieving the goals as detailed in the tables below. Each goal is assigned a target and a maximum level of achievement with a corresponding payout. The Compensation Committee designed the target levels of achievement to be challenging yet reasonably attainable, with maximum awards set at a challenging level of achievement. Levels of achievement for each goal were assessed using a combination of budget, historical performance, peer group performance, and the Company’s forecasted 2025 performance. Triggers and metrics for the year are determined in the first quarter. Each of the three goals is equal in weight as the Committee believes each goal requires a similar focus and is essential to achieving our performance objectives.

  41. 2025 Annual Cash Incentive Plan — Metric Performance Calculation and Actual Performance Results

    | 2025 Annual Incentive Plan Goal | Goal Weighting | Threshold | Target | Maximum | 2025 Actual Performance | | Return on Assets – Consolidated | 33% | 1.04% | 1.18% | 1.37% | 1.65% | | Wholesale Funding Reliance Ratio | 33% | 10.93% | 7.72% | 5.48% | 3.59% | | Earnings Per Share – Consolidated | 34% | $5.80 | $6.60 | $7.40 | $7.36 |

  42. 2025 Annual Cash Incentive Plan — Metric Performance Calculation and Actual Performance Results

    The Wholesale Funding Reliance (“WFR”) ratio is a liquidity measure which gauges the quality of funding the Bank uses to fund the asset side of the balance sheet. A lower ratio indicates that the Bank is funding its interest-earning assets using core customer deposits rather than wholesale funding, which carries higher risk. This metric was new for the Company in 2025. We also focus on Earnings Per Share (“EPS”), which we believe is the best measure of an organization’s performance. Our success in enhancing shareholder value is long-term growth in EPS. Focusing on Return on Assets (“ROA”) ensures that we are good stewards of the assets we are entrusted to oversee by our shareholders. The annual incentive plan goals are calculated from the annual budget approved by the Board in December of each year. The Target goal for each metric is taken directly from the budget. The Threshold and Maximum goals for each metric are calculated based upon a spread in each direction, determined by management in conjunction with the Compensation Committee.

  43. Long-Term Incentive Compensation (“Equity Plan”)

    Long-Term Incentive Compensation (“Equity Plan”) We believe that equity grants are appropriate long-term incentives to link pay and performance. The purpose of granting equity is also to attract and retain key officers and to encourage performance by providing an ownership stake in our Company. We continue to review the practice of granting equity awards annually to ensure that this form of incentive compensation continues to drive our NEOs to achieve our Company’s long-term objectives. In 2025, the Bank continued to utilize its Equity Plan to align executive pay with performance, drive the Company’s strategic goals, and drive superior financial results. The Equity Plan is designed to support the Company’s pay-for-performance philosophy and reward key executives for creating long-term shareholder value. We believe aligning executives with shareholder interests through performance goals and focusing on shareholder value appreciation is essential. Overall, the Equity Plan is designed to meet the objectives as described previously under the “Material Components of Compensation Program” section. The Equity Plan utilizes restricted stock awards with a three-year ratable vesting schedule. The use of restricted stock, or full-value equity grants, remains appropriate as our equity-granting vehicle, as it remains prevalent within the banking industry based on our independent compensation consulting studies and regulatory best practices. The recipients are entitled to receive dividends during their restricted period and have the right to vote shares of restricted stock. Awards are granted and vest on or around March 1 of each year, and the Compensation Committee has the discretion to determine the grant and vesting date.

  45. Treatment of Equity Plan Awards Under Termination Events

    Treatment of Equity Plan Awards Under Termination Events The Equity Plan details the treatment of awards under various employment termination events. If a participant terminates their employment or is terminated for cause, they will forfeit their unvested shares. The Compensation Committee has the discretion to accelerate vesting upon the retirement of an NEO. Shares of restricted stock will become immediately vested upon the occurrence of a change of control of the Company. In exchange for shares of restricted stock, all recipients of long-term incentive awards who are employees of the Bank agree to certain restrictive covenants in the event their employment with the Bank is terminated, including non-solicitation of customers, non-solicitation of employees, and confidentiality obligations.

  46. Incentive Plan Payout Triggers

    Incentive Plan Payout Triggers Below, we summarize the annual cash incentive and long-term incentive plan’s triggers, which must be met before any cash or equity incentive/bonus award is paid. If the criteria below are not met, no incentive awards are paid. We believe these criteria reduce the risk to the Company and ensure that awards are paid only if the Company is in good standing.

  47. Incentive Plan Payout Triggers

    | Incentive Plan Payout Triggers | Criteria | | Non-Performing-Assets to Total Assets — Bank | Must be less than or equal to 2.0% | | Net Promoter Score | Must be 55 or better | | Total Liquidity | Must be 25% or higher | | Regulatory Standing | Bank must be in good regulatory and audit standing | | Employment Status | Employee must be in good standing and actively employed at the time of payout/grant |

  48. Equity Grant Policy

    Equity Grant Policy We do not have a formal equity grant policy. The annual grant of equity awards is generally made in the first quarter of the calendar year. We do not have a program, plan or practice to time our equity grants in coordination with the release of material, non-public information.

  49. Change-in-Control Agreements with NEOs

    Change-in-Control Agreements with NEOs The Company implemented change-in-control (“CIC”) agreements for the NEOs in 2022 and 2023. Pursuant to the CIC agreement, if the executive is terminated without “cause” or resigns for “good reason”, in each case within one year following a “change in control” (as such terms are defined in the agreement), then the executive will receive: (i) a lump sum severance payment equal to a multiple of his base salary (3x, in the case of Mr. Molepske and Mr. McFarlane, or 2x, in the case of the other NEOs); (ii) a lump sum amount equal to the average cash bonus received by the executive over the previous three years; and (iii) reimbursement of health insurance coverage premiums for a specified period (three years, in the case of Mr. Molepske and Mr. McFarlane, or two years, in the case of the other NEOs). In addition, each executive’s outstanding unvested stock awards will become fully vested upon a change in control. See the Potential Payments Upon Termination or Change in Control for additional information.

    CEO Pay Ratio Below, we disclose the Company’s CEO Pay Ratio, as required by Section 953(b) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 402(u) of SEC Regulation S-K. The SEC rules require that we identify our median employee using a consistently applied compensation measure (“CACM”). We identified the median employee in 2025 by examining gross pay, excluding the CEO. This employee population included all full-time, part-time, and seasonal employees as of December 31, 2025. Once we identified our median employee, we determined the annual total compensation of our median employee for 2025. We then calculated the CEO’s and the median employee’s 2025 total compensation in a manner comparable to the CEO compensation provided in the Summary Compensation Table. This information is provided solely for compliance purposes and is not used in other compensation evaluations.

CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS Related Party Transactions Transactions by the Company with related parties are subject to a formal written policy, regulatory requirements, and restrictions. These requirements and restrictions include Sections 23A and 23B of the Federal Reserve Act and the Federal Reserve’s Regulation W, which governs certain transactions by us with our affiliates, and the Federal Reserve’s Regulation O, which governs certain loans by us to executive officers, directors, and principal shareholders. We have adopted policies to ensure compliance with these regulatory requirements and restrictions. In addition, our board of directors has adopted a written policy governing the approval of related-party transactions that complies with all applicable requirements of the SEC and the Nasdaq Stock Market concerning related-party transactions. The Board of Directors is responsible for reviewing and approving all related party transactions and reviewing the procedures used to identify related parties and any transactions with related parties. Under SEC regulations, the Company is required to disclose any transaction occurring in the last fiscal year or that is currently proposed in an amount that exceeds $120,000, in which the Company was or is a participant, and in which an executive officer or director of the Company, or an immediate family member thereof, had or will have a direct or indirect material interest. All transactions between the Company or the Bank and executive officers, directors, principal shareholders (that we are aware of) and affiliates thereof, will, to the best of our efforts, contain terms no less favorable to the Company or the Bank than could have been obtained by them in arms’ length negotiations with unaffiliated persons and will be reviewed and approved by the Board of Directors. In determining whether to approve a related person transaction, the Board will consider all of the relevant and material facts and circumstances available to it, including (if applicable) but not limited to: the benefits to the Company; the impact on a director’s independence in the event the related person is a director, an immediate family member of a director or an entity in which a director is a partner, shareholder or executive officer; the availability of other sources for comparable products or services; the terms of the transaction; and whether the terms are comparable to the terms available to unrelated third parties or to employees generally. After its review, the Board will only approve or ratify related person transactions that are (i) in, or are not inconsistent with, the best interests of the Company and its shareholders, as the Board determines in good faith, (ii) on terms comparable to those that could be obtained in arm’s length dealings with an unrelated third person, and (iii) approved or ratified by a majority of the disinterested members of the Board. The Company did not engage in any transactions requiring disclosure under SEC regulations in 2025. Loans to Related Persons The Bank has had, and expects to have in the future, loans and other banking transactions in the ordinary course of business with directors (including our independent directors) and executive officers of the Company and its subsidiaries, including members of their families or corporations, partnerships or other organizations in which such officers or directors have a controlling interest. In addition, the Bank is subject to the provisions of Section 23A of the Federal Reserve Act, which places limits on the amount of loans or extensions of credit to, or investments in, or certain other transactions with, affiliates and on the amount of advances to third parties collateralized by the securities or obligations of affiliates. The Bank is also subject to the provisions of Section 23B of the Federal Reserve Act which, among other things, prohibits an institution from engaging in certain transactions with certain affiliates unless the transactions are on terms substantially the same, or at least as favorable to such institution or its subsidiaries, as those prevailing at the time for comparable transactions with nonaffiliated companies. In accordance with the Financial Institutions Reform, Recovery, and Enforcement Act of 1989, as amended, to the best of our knowledge, all loans to executive officers, directors, principal shareholders, and any affiliates thereof, are made in the ordinary course of business, are made on the same terms, including interest rates, loan fees, and collateral as those prevailing at the time for comparable transactions with the general public and do not involve more than the normal risk of repayment or present other unfavorable features. During 2025, no executive officer, director, principal shareholder (that we are aware of), or any affiliate of the Company or the Bank had loans outstanding at preferred interest rates or other terms from the Company or the Bank. PROPOSAL 2 — RATIFICATION OF APPOINTMENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

  77. Pay Versus Performance: Graphical Description

    The Audit Committee has appointed Forvis Mazars, LLP (“Forvis”) as the independent registered public accounting firm to audit the Company’s financial statement for the fiscal year ending December 31, 2026. Although it is not required, the Board is submitting the selection of Forvis as our independent registered public accounting firm to our shareholders for ratification as a matter of good corporate governance. The Board recommends that our shareholders ratify such an appointment. Even if the shareholders ratify the appointment of Forvis, the Audit Committee, in its discretion, could decide to terminate the engagement of Forvis and engage another audit firm if it determines such action is necessary or desirable. If the required shareholder vote does not ratify the appointment, the vote will be considered in connection with the engagement of an independent auditor for 2026. The Audit Committee will reconsider the appointment and may also decide to maintain the appointment. Representatives of Forvis will attend the Annual Meeting and have the opportunity to make a statement if they so desire. Bank First encourages all shareholders to ask questions of and provide comments to representatives of Forvis in advance of the Meeting by contacting our Shareholder Services team at (920) 652-3360 or ShareholderServices@bankfirst.com. Representatives from Forvis will be available to respond to questions at the Annual Meeting. THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT YOU VOTE “FOR” THE PROPOSAL TO RATIFY THE APPOINTMENT OF FORVIS MAZARS, LLP AS THE COMPANY’S INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR THE FISCAL YEAR ENDING DECEMBER 31, 2026. INFORMATION REGARDING THE COMPANY’S INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM The Company was notified that Dixon Hughes Goodman LLP, its independent registered public accounting firm, merged with BKD, LLP on June 1, 2022. The combined practice operated under the name FORVIS, LLP. Effective June 1, 2024, FORVIS, LLP merged with Mazars to form Forvis Mazars, LLP. As a result of these mergers, Forvis Mazars, LLP is the Company’s independent registered public accounting firm and has served in such capacity for the years ended December 31, 2025, 2024, 2023, and 2022. Fees Billed by the Company’s Independent Registered Public Accounting Firms This table presents fees for professional audit services rendered by the Company’s independent registered public accounting firm for the audit of the Company’s annual financial statements during the years ended December 31, 2025, 2024, 2023, and 2022, and fees billed for other services rendered by the firms during those periods.

    | Year Ended December 31 | 2025 | 2024 | 2023 | 2022 | | Audit fees | $557,480 | $500,000 | $439,250 | $347,094 | | Audit-related fees | $0 | $0 | $0 | $0 | | Tax fees | $0 | $0 | $0 | $0 | | All other fees | $0 | $0 | $0 | $0 | | Total | $557,480 | $500,000 | $439,250 | $347,094 |

  79. Pay Versus Performance: Graphical Description

    Audit fees These amounts represent fees of the independent registered public accounting firms for the audit of our annual consolidated financial statements, the audit of internal controls over financial reporting (FDICIA), and the services that an independent auditor would customarily provide in connection with subsidiary audits, statutory requirements, regulatory filings, and similar engagements for the year. Audit fees also include advice about accounting matters that arose in connection with or as a result of the audit or the review of periodic financial statements. Audit-related fees Audit-related fees generally consist of assurance and related services that are reasonably related to the performance of the audit or review of the Company’s consolidated financial statements or internal controls over financial reporting. This category may include fees related to the performance of audits and attest services not required by statute or regulation, due diligence related to mergers, acquisitions, and investments, and accounting consultations on applying generally accepted accounting principles to proposed transactions. These services support the evaluation of the effectiveness of internal controls over revenue recognition, enhancing the independent auditor’s understanding of our products and controls. Tax fees Tax fees, of which there were none, generally fall into two categories: tax compliance and return preparation and tax planning and advice. The tax compliance and return preparation services consist of preparing original and amended tax returns and claims for refunds. All other fees All other fees, of which there were none, consist of permitted services that do not meet the criteria above, including training activities, economic, industry, and accounting subscriptions, as well as surveys. The Audit Committee concluded that the provision of the non-audit services listed above is compatible with maintaining the independence of Forvis Mazars, LLP. Policy on Audit Committee Pre-Approval of Audit and Permissible Non-Audit Services of Independent Registered Public Accounting Firm The Audit Committee has a policy for pre-approval of all audit and permissible non-audit services provided by the independent auditor. Each year, the Audit Committee approves the terms on which the independent auditor is engaged for the ensuing fiscal year. The Audit Committee, as permitted by its pre-approval policy, occasionally delegates the approval of certain permitted services or classes of services to a member of management. All fees paid to Forvis Mazars, LLP for the fiscal years ended December 31, 2025, 2024, 2023, and 2022 were pre-approved by the Audit Committee. Audit Committee Report The Audit Committee has the responsibilities and powers set forth in its charter, which include the obligation to assist the Board of Directors in its oversight of our accounting and financial reporting principles and policies and internal audit controls and procedures, the integrity of our financial statements, our compliance with legal and regulatory requirements, the independent auditor’s qualifications and independence, and the performance of the independent auditor and our internal audit function. The Audit Committee is also required to prepare this report to be included in our annual proxy statement pursuant to the SEC’s proxy rules. Management is responsible for the preparation, presentation, and integrity of our financial statements and for maintaining appropriate accounting and financial reporting principles and policies and internal controls and procedures to ensure compliance with accounting standards and applicable laws and regulations. The internal auditor is responsible for testing such internal controls and procedures. Our independent registered public accounting firm is responsible for planning and carrying out a proper audit of our annual financial statements, reviews of our quarterly financial statements prior to filing each quarterly report on Form 10-Q, and other procedures. The Audit Committee reviews our financial reporting process. In this context, the Audit Committee: • has reviewed and discussed with management the audited financial statements for the year ended December 31, 2025; • has discussed with Forvis Mazars, LLP, the Company’s independent registered public accounting firm, the matters required to be discussed by Auditing Standard No. 1301, Communications with Audit Committees, as adopted by the Public Company Accounting Oversight Board (“PCAOB”); • has discussed with Forvis Mazars the matters required to be discussed by the applicable requirements of the PCAOB and the SEC; and • has received the written disclosures and the letter from Forvis Mazars, required by PCAOB Rule 3526 (“Independence Discussions with Audit Committees”), as modified or supplemented, and has discussed the independent accountant’s independence with Forvis Mazars. Based on this review and the discussions above, the Audit Committee recommended that our Board of Directors include the audited consolidated financial statements in our Annual Report on Form 10-K for the year ended December 31, 2025, for filing with the SEC. This report is submitted on behalf of the members of the Audit Committee and shall not be deemed “soliciting material” or to be “filed” with the SEC, nor shall it be incorporated by any general statement incorporating by reference this proxy statement into any filing under the Securities Act of 1933, as amended, or the Securities Exchange Act of 1934, as amended, except to the extent that we specifically incorporate this information by reference and shall not otherwise be deemed filed under these Acts. Respectfully submitted by the Audit Committee of the Board, Daniel C. McConeghy, Chair Stephen E. Johnson Todd A. Sprang Michael S. Stayer-Suprick PROPOSAL 3 — ADVISORY VOTE TO APPROVE NAMED EXECUTIVE OFFICER COMPENSATION In accordance with Section 14A of the Exchange Act and related rules of the SEC, we provide our shareholders with a “say-on-pay” vote, an opportunity to vote on an advisory basis on the compensation paid to our named executive officers as disclosed pursuant to Item 402 of Regulation S-K. Accordingly, you may vote on the following resolution: “Resolved, that the shareholders approve, on an advisory basis, the compensation of Bank First Corporation’s named executive officers, including the Compensation Discussion and Analysis, the accompanying compensation tables, and the related narrative disclosure contained in the Proxy Statement.” As discussed in detail in the Compensation Discussion and Analysis section of this Proxy Statement, the Company’s executive compensation philosophy is designed to provide a total compensation package that is competitive with market practices while varying awards to recognize Company and individual performance. Our compensation program is designed to be performance-based, offering the opportunity to earn higher compensation (via our annual cash and long-term incentive plans) if performance warrants. The objective is to provide competitive pay for achieving performance goals consistent with the Company’s business objectives and its performance compared to the performance of other financial institutions. The Company’s philosophy is that actual compensation should exceed the market when superior performance is achieved and be lower than the market when performance falls below expectations. We firmly believe that the information we have provided in this Proxy Statement demonstrates that our executive compensation program was designed appropriately and is working to ensure the alignment of management and shareholder interests. This vote is not intended to address any specific compensation item but rather the overall compensation of our named executive officers. It is also not a vote on director compensation or our compensation policies as they relate to risk management.

  80. Pay Versus Performance: Graphical Description

    Because this is an advisory vote, it will not affect any compensation already paid or awarded. It will not be binding upon or overrule any decisions made by the Compensation Committee or the Board. Nevertheless, the Board and the Compensation Committee value our shareholders’ views and intend to consider the outcome of the vote, along with other relevant factors, when making future-named executive officer compensation decisions. THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT SHAREHOLDERS VOTE “FOR” THE ADVISORY APPROVAL OF BANK FIRST CORPORATION’S NAMED EXECUTIVE OFFICER COMPENSATION, AS DISCLOSED IN THIS PROXY STATEMENT. PROPOSAL 4 — APPROVAL OF AMENDMENT TO THE ARTICLES OF INCORPORATION TO MODIFY SHAREHOLDER APPROVAL REQUIREMENTS FOR CERTAIN FUNDAMENTAL TRANSACTIONS The Board of Directors recommends that shareholders approve an amendment to Article VIII of the Company’s Restated Articles of Incorporation (the “Articles”) to remove the requirement that certain mergers, acquisitions, or sales of substantially all assets be approved by the affirmative vote of 80% of the outstanding shares. This supermajority voting requirement is not mandated by Wisconsin law and is no longer necessary for the protection of shareholders. If approved, the amendment would eliminate the supermajority vote requirement and allow such transactions to be approved in accordance with the default voting standards under the Wisconsin Business Corporation Law (“WBCL”), Wisconsin Statutes Chapter 180. The provision was originally adopted as an anti-takeover measure. However, the Board has determined that the WBCL already provides robust protections for shareholders. Moreover, supermajority requirements can limit strategic flexibility and delay or prevent value-enhancing transactions, as well as give minority shareholders disproportionate blocking power. Removing the supermajority requirement aligns the Company’s governance with modern best practices and enhances the Board’s ability to act in the best interests of all shareholders. In addition, Section 180.11032 of the WBCL requires shareholder approval of a merger or interest exchange by a majority of all votes entitled to be cast. However, such approval is not required if all the following conditions are met: 1. The articles of incorporation of the surviving domestic corporation will not differ, except for amendments enumerated in s. 180.1002, from its articles of incorporation before the merger. 2. Each shareholder of the surviving domestic corporation whose shares were outstanding immediately before the effective date of the merger will hold the same number of shares, with identical designations, preferences, limitations and relative rights, immediately after. 3. The number of voting shares outstanding immediately after the merger, plus the number of voting shares issuable as a result of the merger, either by the conversion of securities issued pursuant to the merger or the exercise of rights or warrants issued pursuant to the merger, will not exceed by more than 20% the total number of voting shares of the surviving domestic corporation outstanding immediately before the merger. 4. The number of participating shares outstanding immediately after the merger, plus the number of participating shares issuable as a result of the merger, either by the conversion of securities issued pursuant to the merger of the exercise of rights or warrants issued pursuant to the merger, will not exceed by more than 20% the total number of participating shares of the surviving domestic corporation outstanding immediately before the merger. The proposed amendment would revise Article VIII of the Articles to provide that, except as otherwise expressly provided in the WBCL, any (i) any merger or consolidation of the Company with one or more other corporations (regardless of which is the surviving corporation) and (ii) any sale, lease or exchange of all or substantially all of the property and assets of the Company to or with one or more other corporations, persons or other entities shall require the affirmative vote of the holders of at least a majority of the outstanding shares of capital stock of the Corporation entitled to vote on the matter, rather than the current requirement of the affirmative vote of the holders of at least 80% of the outstanding shares of capital stock of the Corporation entitled to vote on the matter. No other changes to the Articles are proposed. A complete copy of the proposed amendment to the Articles has been attached as Appendix A to this Proxy Statement. THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT SHAREHOLDERS VOTE “FOR” THE AMENDEMENT TO THE ARTICLES OF INCORPORATION TO MODIFY SHAREHOLDER APPROVAL REQUIREMENTS FOR CERTAIN FUNDAMENTAL TRANSACTIONS. SUBMISSION OF SHAREHOLDER PROPOSALS AND SHAREHOLDER COMMUNICATIONS Shareholder Proposals For a shareholder proposal to be considered for inclusion in the Company’s Proxy Statement for the 2027 annual meeting of shareholders, the written proposal must be received by the Corporate Secretary of the Company at the address below.

The Secretary must receive this notice no earlier than February 15, 2027, and no later than March 15, 2027.

The notice of a proposed director nomination must provide information as required in the Bylaws of the Company and the information required by Sec Rule 14a-19, if applicable. In general, our Bylaws require that the notice of a director nomination include your name, address and the number of shares you own beneficially or of record; the name, age, business address, residence address and principal occupation of the nominee; and the number of shares owned beneficially or of record by the nominee. In addition, each nomination shall include a representation that the shareholder is entitled to vote at the annual meeting and intends to appear in person or by proxy at the meeting to make the nomination and provide background information about the nominee. It is the policy of the Governance and Nominating Committee to consider all timely and properly submitted nominations for directors.

Shareholder Communications

  81. Pay Versus Performance: Graphical Description

    Shareholders wishing to communicate with the Board, a particular director, or the Corporate Secretary may do so in writing directed to the Corporate Secretary of the Company, Kelly M. Dvorak, 402 N. 8th Street, P.O. Box 10, Manitowoc, WI 54221-0010. The Corporate Secretary is responsible for reviewing all communications addressed to our Board, any committee, or any specific director to determine whether such communications require Board, committee, or personal review, response, or action. Generally, the Corporate Secretary will not forward any communication relating to Company products and services, solicitations, or other improper or irrelevant topics to the Board, any committee, or any specific director. If, however, the Corporate Secretary determines that a communication relates to corporate governance or otherwise requires review, response or action by the Board, any committee or any specific director, then she will promptly send a copy of such communication to each director serving on the Board, the applicable committee or the applicable director. Shareholder Engagement The Company and our Board believe that accountability to our shareholders is key to sound corporate governance principles. As such, regular and transparent communication with our shareholders is essential to our long-term success. Throughout the year, members of our management team meet regularly with some of our shareholders to discuss our corporate strategy, financial performance, long-term objectives, credit risks, capital management, enterprise risk management, corporate governance, ESG-related matters, and executive compensation. By regularly engaging with our shareholders, we provide perspective on our governance policies and executive compensation practices and seek input from these shareholders to ensure that we are addressing their questions and concerns. Our ongoing shareholder engagement program encompasses many initiatives, including: Scheduled meetings with our larger shareholders; • Responding to institutional and retail shareholder correspondence and inquiries; • Attending and participating at several industry conferences each year; • Regular engagement with analysts who cover the Company to reinforce key themes related to our business strategy and financial performance. This communication helps to ensure that written reports about the Company, including earnings projections, are reasonable and consistent with our stated objectives; and • Scheduled non-deal road shows and virtual meetings. Throughout the year, we contacted a number of the Company’s larger shareholders. This allowed us to better understand, and address shareholder questions and concerns related to key issues, including our financial performance, the interest rate environment, our strategic objectives, and our long-term growth strategy. Feedback and perspectives shared during these engagement meetings were discussed by executive management and the Board and influenced several changes and disclosure enhancements. We look forward to the continued enhancement of our shareholder engagement program in 2026. We are committed to an open dialogue where investor views and priorities may be gathered and discussed, informing and guiding a deliberate decision-making process with a diverse shareholder base in mind. Householding To further reduce printing costs and postage fees, we may adopt a practice approved by the SEC called “householding.” Under this practice, shareholders who have the same address and last name and have elected to receive paper copies of proxy materials will receive only one copy of our proxy materials unless one or more of these shareholders notifies us that they wish to continue receiving individual copies. Upon request, the Company will promptly deliver a separate copy of the Proxy Statement to a shareholder at a shared address to which a single copy of the documents was delivered. Conversely, shareholders sharing an address who receive multiple copies of Annual Reports or Proxy Statements may request delivery of a single copy. You can contact the Company by calling (920) 652-3244 or by writing to Corporate Secretary, Bank First Corporation, 402 N. 8th Street, P.O. Box 10, Manitowoc, WI 54221-0010, or by sending an email to kdvorak@bankfirst.com to request a separate copy of the proxy materials and for future meetings or, if you are currently receiving multiple copies, to receive only a single copy in the future. Shareholders who beneficially own shares of our common stock held in street name may contact their broker, bank or other agent as your nominee to request information about householding.
