#### MERGER PROPOSED — YOUR VOTE IS VERY IMPORTANT
To the Shareholders of Centre 1 Bancorp, Inc.:

The boards of directors of Bank First Corporation, or Bank First, and Centre 1 Bancorp, Inc., or Centre, have each unanimously approved the acquisition of Centre by Bank First. The acquisition will be accomplished pursuant to the terms of an Agreement and Plan of Merger, dated as of July 17, 2025, which we refer to as the merger agreement, by and between Bank First and Centre, whereby Centre will be merged with and into Bank First, which we refer to as the merger.

Immediately following the merger of Centre with and into Bank First, The First National Bank and Trust Company, a wholly owned bank subsidiary of Centre, will merge with and into Bank First's wholly owned bank subsidiary, Bank First, N.A., with Bank First, N.A. as the surviving bank, which we refer to as the bank merger.

If the merger is completed, each share of Centre common stock issued and outstanding immediately prior to the effective time of the merger will be converted into the right to receive 0.9200 of a share (the "exchange ratio") of Bank First common stock, with cash paid in lieu of fractional shares (the "merger consideration"). Notwithstanding the foregoing, the merger consideration is subject to a downward adjustment if Centre's tangible book value (as calculated per the merger agreement) is less than $83,587,000 at the time of the closing of the merger.

Although the number of shares of Bank First common stock that Centre shareholders will receive is fixed, the market value of the merger consideration will fluctuate with the market price of Bank First common stock and will not be known at the time Centre shareholders vote on the merger. Bank First common stock is currently quoted on the Nasdaq Capital Market under the symbol "BFC." On July 17, 2025, the last full trading day before the public announcement of the merger agreement, based on the last reported sale price of Bank First common stock of $125.78 per share, the exchange ratio represented approximately $115.72 in value for each share of Centre common stock to be converted into Bank First common stock. Based on the closing sale price of Bank First common stock of $124.12 per share on September 25, 2025, the latest practicable trading date prior to the printing of this proxy statement/prospectus, the exchange ratio represented approximately $114.19 in value for each share of Centre common stock to be converted into Bank First common stock. **We urge you to obtain current market quotations for the price of Bank First common stock (trading symbol "BFC") because the value of the merger consideration will fluctuate based on Bank First's common stock price**.

Centre will hold a special meeting of its shareholders, referred to as the Centre special meeting, where Centre shareholders will be asked to consider and vote upon (1) a proposal to approve the merger agreement and the merger, and (2) a proposal to adjourn the Centre special meeting, if necessary or appropriate, to solicit additional proxies in favor of the proposal to approve the merger agreement and the merger.

The Centre special meeting will be held on November 13, 2025, at 9:00 a.m., Central Time, at 345 E Grand Ave., Beloit, Wisconsin 53511, subject to any adjournment or postponement thereof.

Each of Bank First and Centre expects that the merger will qualify as a "reorganization" within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended, which we refer to as the Code, with the result that Centre common stock exchanged for Bank First common stock will generally be tax-free.

**Your vote is important**. Completion of the merger is subject to the approval of the merger agreement by the shareholders of Centre. Regardless of whether or not you plan to attend the Centre special meeting, please take the time to authorize a proxy to vote your shares in accordance with the instructions contained in this proxy statement/prospectus. If you submit a properly signed proxy card without indicating how you want to vote, your proxy will be counted as a vote "**FOR**" the proposal to approve the merger agreement and "**FOR**" the proposal to adjourn the Centre special meeting, if necessary or appropriate, to solicit additional proxies in favor of the proposal to approve the merger agreement. The failure to vote by submitting your proxy or attending the Centre special meeting and voting in person will have the same effect as a vote against approval of the merger agreement. Submitting a proxy now will not prevent you from being able to vote in person at the Centre special meeting. If you hold your shares in "street name," through a bank, broker or other nominee, you should instruct your bank, broker or other nominee how to vote in accordance with the voting instruction form you receive from your bank, broker or other nominee.

 **The board of directors of Centre has determined that the merger agreement and the transactions contemplated thereby, including the merger, are advisable and in the best interests of the shareholders of Centre, has unanimously approved the merger agreement and the merger and unanimously recommends that the shareholders of Centre vote "FOR" the proposal to approve the merger agreement and "FOR" the proposal to adjourn the Centre special meeting, if necessary or appropriate, to solicit additional proxies in favor of the proposal to approve the merger agreement.** 

 **This proxy statement/prospectus describes the Centre special meeting, the merger, the merger agreement, other documents related to the merger and other related matters. Please carefully read this entire proxy statement/prospectus, including "Risk Factors," beginning on page [30](#tRIFA), for a discussion of the risks relating to the proposed merger and owning Bank First common stock after the merger. You also can obtain information about Bank First and Centre from documents that have been filed with the Securities and Exchange Commission that are incorporated in the proxy statement/prospectus by reference.** 

If you have any questions concerning the merger, please contact Don O'Day, President, at (608) 363-8007 or Don.Oday@bankatfirstnational.com, or Jerry Ritzert, Chief Financial Officer, at (608) 363-8080 or Jerry.Ritzert@bankatfirstnational.com. We look forward to seeing you at the meeting.

#### CENTRE 1 BANCORP, INC. 345 East Grand Avenue Beloit, WI 53511 (608) 363-8000

#### NOTICE OF SPECIAL MEETING OF SHAREHOLDERS To Be Held on November 13, 2025
To the Shareholders of Centre 1 Bancorp, Inc.:

NOTICE IS HEREBY GIVEN that Centre 1 Bancorp, Inc., or Centre, will hold a special meeting of its shareholders (which we refer to as the "Centre special meeting") on November 13, 2025, at 9:00 a.m., Central Time, at 345 E Grand Ave., Beloit, Wisconsin 53511, to consider and vote upon the following matters:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 1.

A proposal to approve the Agreement and Plan of Merger (which we refer to as the "merger agreement"), dated as of July 17, 2025, by and between Centre and Bank First Corporation (which we refer to as "Bank First"), and the transactions contemplated by the merger agreement, including the merger of Centre with and into Bank First, with Bank First as the surviving company (which we refer to as the "merger"), each as more fully described in the accompanying proxy statement/prospectus (which we refer to as the "Centre merger proposal"); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 2.

A proposal to adjourn the Centre special meeting, if necessary or appropriate, to solicit additional proxies in favor of the Centre merger proposal (which we refer to as the "Centre adjournment proposal").

The Centre board of directors has fixed the close of business on September 26, 2025 as the record date for the Centre special meeting. Only Centre shareholders of record as of the record date are entitled to notice of, and to vote at, the Centre special meeting or any adjournment or postponement of the Centre special meeting. Any shareholder entitled to attend and vote at the Centre special meeting is entitled to appoint a proxy to attend and vote on such shareholder's behalf. The Centre special meeting may be adjourned from time to time upon approval of holders of Centre common stock without any notice other than by announcement at the meeting of the adjournment thereof, and any and all business for which notice is hereby given may be transacted at such adjourned meeting.

The affirmative vote of a majority of the outstanding shares of Centre common stock entitled to vote thereon is required to approve the Centre merger proposal. Assuming a quorum is present, approval of the Centre adjournment proposal requires the votes cast favoring the action to exceed the votes cast opposing the action. Centre will transact no other business at the Centre special meeting, except for business properly brought before the Centre special meeting or any adjournment or postponement thereof.

Centre common shareholders must approve the Centre merger proposal in order for the merger to occur. If Centre common shareholders fail to approve the Centre merger proposal, the merger will not occur. The proxy statement/prospectus accompanying this notice explains the merger agreement and the transactions contemplated thereby, as well as the proposals to be considered at the Centre special meeting. Please review the proxy statement/prospectus carefully.

Holders of record of Centre common stock have the right to dissent from the merger agreement and the merger and obtain payment in cash of the appraised fair value of their shares of Centre common stock under applicable provisions of the Wisconsin Business Corporation Law, or WBCL. In order for a holder of Centre common stock to perfect his, her or its right to dissent, such holder must carefully follow the procedure set forth in the WBCL. A copy of the applicable statutory provisions of the WBCL is included as <u>Annex B</u> to the accompanying proxy statement/prospectus and a summary of these provisions can be found under the caption "The Merger — Dissenters' Rights," beginning on page [65](#tDIRI) of the proxy statement/prospectus. The merger may not be completed if the holders of more than 10% of the outstanding shares of Centre common stock exercise dissenters' rights.

#### QUESTIONS AND ANSWERS
 *The following are answers to certain questions that Centre shareholders may have regarding the proposed transaction between Bank First and Centre and the proposals being considered at the Centre special meeting. We urge you to carefully read the remainder of this proxy statement/prospectus, including the annexes and the documents incorporated by reference into this proxy statement/prospectus, because the information in this section may not provide all the information that might be important to you in determining how to vote.* 

 *Unless the context otherwise requires, references in this proxy statement/prospectus to: (1) "Bank First" refers to Bank First Corporation, a Wisconsin corporation, and its affiliates; (2) "Bank First, N.A." refers to Bank First, N.A., a national banking association and a direct wholly-owned subsidiary of Bank First; (3) "Centre" refers to Centre 1 Bancorp, Inc., a Wisconsin corporation, and its affiliates; and (4) "First National Bank" refers to The First National Bank and Trust Company, a national banking association and the wholly-owned bank subsidiary of Centre.* 

#### Q:

#### Why am I receiving this proxy statement/prospectus?
**A:**

Bank First and Centre have entered into an Agreement and Plan of Merger on July 17, 2025 (which we refer to as the "merger agreement"), pursuant to which Centre will merge with and into Bank First, with Bank First continuing as the surviving entity (which we refer to as the "merger"). Immediately following the merger, Centre's wholly-owned banking subsidiary, First National Bank, will merge with and into Bank First's wholly-owned banking subsidiary, Bank First, N.A., with Bank First, N.A. as the surviving bank (which we refer to as the "bank merger"), pursuant to the terms of the Plan of Merger and Merger Agreement entered into by Bank First, N.A. and First National Bank on July 17, 2025 (which we refer to as the "bank merger agreement"). A copy of the merger agreement is attached to this proxy statement/prospectus as <u>Annex A</u>.

The merger cannot be completed unless, among other things, the majority of the outstanding shares of Centre common stock entitled to vote at the Centre special meeting vote in favor of the proposal to approve the merger agreement and the merger, which we refer to as the Centre merger proposal.

In addition, Centre is soliciting proxies from its shareholders with respect to a proposal to approve one or more adjournments of the Centre special meeting, if necessary or appropriate, to solicit additional proxies if there are insufficient votes at the time of such adjournment to approve the Centre merger proposal, which we refer to as the Centre adjournment proposal. The completion of the merger is not conditioned upon shareholder approval of the Centre adjournment proposal.

This proxy statement/prospectus contains important information about the merger agreement, the merger and the proposals being voted on at the Centre special meeting, and you should read it carefully. This is a proxy statement/prospectus because (1) Centre is soliciting proxies from the Centre shareholders and the proxy statement provides important information about the Centre special meeting to vote on the Centre merger proposal and the Centre adjournment proposal, and (2) Bank First will issue shares of Bank First common stock to holders of Centre common stock in connection with the merger, and the prospectus provides important information about such shares. The enclosed materials allow Centre shareholders to authorize a proxy to vote their shares without attending the Centre special meeting.

**Your vote is important. We encourage you to submit your proxy as soon as possible**.

#### Q:

#### What will I receive in the merger?
**A:**

If the merger is completed, each share of Centre common stock issued and outstanding immediately prior to the effective time of the merger will be converted into the right to receive 0.9200 of a share, or the exchange ratio, of Bank First common stock. Notwithstanding the foregoing, the merger consideration is subject to a downward adjustment if Centre's tangible book value (as calculated per the merger agreement) is less than $83,587,000 at the time of the closing of the merger. Each outstanding share of Bank First's common stock will remain outstanding and unaffected by the merger.

------

[**TABLE OF CONTENTS**](#TOC)

Bank First will not issue any fractional shares of Bank First common stock in the merger. Instead, a Centre shareholder who otherwise would have received a fraction of a share of Bank First common stock will receive an amount in cash (without interest and rounded to the nearest cent) determined by multiplying (1) the per share volume weighted average price of Bank First common stock as reported on the Nasdaq Capital Market during the ten consecutive trading days immediately prior to the fifth trading day prior to closing by (2) the fraction of a share (rounded to the nearest one hundredth of a share) of Bank First common stock to which such shareholder would otherwise be entitled to receive.

Centre may terminate the merger agreement if (i) the average closing price of Bank First common stock over the ten consecutive trading days immediately preceding the date that all regulatory approvals for the merger has been received is less than $110.06, and (ii) the decline in the price of Bank First common stock (as measured by the average closing price divided by $125.78) is more than 12.5% greater than the decline in the Nasdaq Bank Index (as measured by dividing the average closing price of the Nasdaq Bank Index over the ten trading days immediately preceding the date that all regulatory approvals for the merger has been received by $4,535.06); *provided, however*, that Bank First has the option, but not the obligation, to adjust the exchange ratio to prevent the termination of merger agreement.

#### Q:

#### What happens to outstanding Centre restricted stock units and options?
**A:**

Immediately prior to the effective time of the merger, all outstanding Centre performance-based restricted stock units and Centre time-based restricted stock units granted under a Centre stock plan (with we collectively refer to as "Centre restricted stock") will become fully vested. At the effective time of the merger, each share of Centre restricted stock that is outstanding prior to the closing of the merger will be cancelled and converted automatically (without any further action on part of the holder thereto) into the right to receive the merger consideration for the applicable number of shares. Payments will be made without interest and subject to tax withholdings.

At the effective time of the merger, each option to purchase shares of Centre common stock, whether vested or unvested, will be cancelled and converted into the right to receive an amount in cash, without interest, equal to the product of (1) the total number of shares of Centre common stock subject to such option and (2) the excess, if any, of the per share volume weighted average price of Bank First common stock as reported on the Nasdaq Capital Market during the ten consecutive trading days immediately prior to the fifth trading day prior to closing over the exercise price per share of Centre common stock under such option, less applicable taxes.

#### Q:

#### Will the shares of Bank First common stock that Centre shareholders receive in the merger be freely transferable?
**A:**

Yes. The Bank First common stock issued in the merger will be transferable free of restrictions under federal and state securities laws.

#### Q:

#### Will the value of the merger consideration change between the date of this proxy statement/prospectus and the time the merger is completed?
**A:**

Yes. The value of the merger consideration may fluctuate based upon the market value for Bank First common stock between the date of this proxy statement/prospectus and the completion of the merger. Centre shareholders will receive 0.9200 of a share of Bank First common stock for each share of Centre common stock they hold. Any fluctuation in the market price of Bank First common stock after the date of this proxy statement/prospectus will change the value of the shares of Bank First common stock that Centre shareholders may receive.

#### Q:

#### How does Centre's board of directors recommend that I vote at the Centre special meeting?
**A:**

Centre's board of directors has unanimously approved the merger agreement and the transactions contemplated thereby, including the merger, and unanimously recommends that you vote "**FOR**" the Centre merger proposal and "**FOR**" the Centre adjournment proposal (if necessary or appropriate).

#### Q:

#### When and where is the Centre special meeting?
**A:**

The Centre special meeting will be located at 345 E Grand Ave., Beloit, Wisconsin 53511, on November 13, 2025, at 9:00 a.m., Central Time.

#### Q:

#### What do I need to do now?
**A:**

After you have carefully read this proxy statement/prospectus and have decided how you wish to vote your shares, please authorize a proxy to vote your shares by promptly completing and returning the enclosed proxy card so that your shares are represented and voted at the Centre special meeting. If you are a registered shareholder, you must complete, sign, date and mail your proxy card in the enclosed postage-paid return envelope as soon as possible. If you hold your shares in "street name", through a bank, broker or other nominee, you must direct your bank, broker or other nominee how to vote in accordance with the instructions you have received from your bank, broker or other nominee. A shareholder who holds shares in "street name" through a bank, broker or other nominee who desires to attend the Centre special meeting in person must bring proof of beneficial ownership as of the record date, such as a letter from the bank, broker or other nominee that is the record owner of such beneficial owner's shares, a brokerage account statement or the voting instruction form provided by the broker. Submitting your proxy by mail or directing your bank, broker or other nominee to vote your shares will ensure that your shares are represented and voted at the Centre special meeting. Your proxy card must be received prior to the Centre special meeting on November 13, 2025, to be counted.

#### Q:

#### What constitutes a quorum for the Centre special meeting?
**A:**

Holders representing at least a majority of the issued and outstanding shares of Centre common stock entitled to vote at the Centre special meeting must be present, in person or represented by proxy, to constitute a quorum. Abstentions and broker non-votes, if any, will be included in determining the number of shares present at the meeting for the purpose of determining the presence of a quorum. If a quorum is not present, the Centre special meeting will be postponed until the holders of the number of shares of Centre common stock required to constitute a quorum attend. If you submit a properly executed proxy card, even if you abstain from voting, your shares of Centre common stock will be counted for purposes of determining whether a quorum is present at the Centre special meeting. If additional votes must be solicited to approve the Centre merger proposal, it is expected that the Centre special meeting will be adjourned to solicit additional proxies if the Centre shareholders approve the Centre adjournment proposal.

#### Q:

#### What is the vote required to approve each proposal?
**A:**

*Centre merger proposal*: Approval of the Centre merger proposal requires the affirmative vote of a majority of the outstanding shares of Centre common stock entitled to vote thereon. If you fail to vote in person or by proxy or fail to instruct your bank, broker or other nominee to vote, or if you mark "**ABSTAIN**" on your proxy card, with respect to the Centre merger proposal, it will have the same effect as a vote "**AGAINST**" the Centre merger proposal.

*Centre adjournment proposal*: Assuming a quorum is present, approval of the Centre adjournment proposal (if necessary or appropriate) requires the votes cast favoring the action to exceed the votes cast opposing the action. If you fail to vote in person or by proxy or fail to instruct your bank, broker or other nominee to vote, or if you mark "**ABSTAIN**" on your proxy card, with respect to the Centre adjournment proposal, you will not be deemed to have cast a vote with respect to such proposal, and it will have no effect on such proposal.

#### Q:

#### What would happen if the Centre adjournment proposal does not get approved by Centre shareholders?
**A:**

The completion of the merger is not conditioned upon shareholder approval of the Centre adjournment proposal. If a quorum is present at the Centre special meeting and the Centre adjournment proposal is not approved and there are not sufficient votes at the time of the Centre special meeting to approve the Centre merger proposal, then the Centre board of directors will not have the ability to adjourn to solicit additional votes and the Centre merger proposal will not be approved.

#### Q:

#### Who may solicit proxies on Centre's behalf?
**A:**

In addition to solicitation of proxies by Centre by mail, proxies may also be solicited by Centre's directors and employees personally, and by telephone, facsimile or other means.

------

[**TABLE OF CONTENTS**](#TOC)

#### Q:

#### Why is my vote important?
**A:**

If you do not submit a proxy or vote in person, it may be more difficult for Centre to obtain the necessary quorum to hold the Centre special meeting. In addition, your failure to submit a proxy or vote in person, or failure to instruct your bank, broker or other nominee how to vote, or abstention will have the same effect as a vote against approval of the Centre merger proposal. The Centre merger proposal must be approved by the affirmative vote of the holders of at least a majority of the outstanding shares of Centre common stock entitled to vote at the Centre special meeting. **Centre's board of directors unanimously recommends that you vote "FOR" the Centre merger proposal**.

#### Q:

#### How many votes do I have?
**A:**

Centre shareholders are entitled to one vote on each proposal to be considered at the Centre special meeting for each share of Centre common stock owned as of the close of business on September 26, 2025, which is the record date for the Centre special meeting.

#### Q:

#### What is the difference between a shareholder of record and a "street name" holder?
**A:**

If you are a shareholder of Centre and if your shares of Centre common stock are registered directly in your name, you are considered the shareholder of record with respect to those shares of stock. If your shares of stock are held in a stock brokerage account or by a bank or other nominee, the nominee is considered the record holder of those shares. You are considered the beneficial owner of these shares, and your shares are held in "street name." If your shares are held in street name, this proxy statement/prospectus and the proxy card, as applicable, have been forwarded to you by your nominee. As the beneficial owner, you have the right to direct your nominee concerning how to vote your shares by using the voting instructions your nominee included in the mailing or by following its instructions for voting.

#### Q:
 **If my shares are held in "street name" by my bank, broker or other nominee, will my bank, broker or other nominee automatically vote my shares for me?** 

**A:**

No. Your bank, broker or other nominee cannot vote your shares without instructions from you. You should instruct your bank, broker or other nominee how to vote your shares in accordance with the instructions provided to you. Please check the voting form used by your bank, broker or other nominee.

#### How do I vote?
**A:**

If you are a shareholder of record as of September 26, 2025, the Centre record date, you may have your shares of Centre common stock voted on the matters to be presented at the Centre special meeting in any of the following ways:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • **You may vote by mail**. You may vote by mail by completing, signing, dating and returning the enclosed proxy card in the accompanying prepaid reply envelope.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • **You may vote in person at the meeting**. You may vote by attending the Centre special meeting and casting your vote in person.

If you intend to submit your proxy by mail, your completed proxy card must be received prior to the date of the Centre special meeting. If you are a shareholder of record of Centre common stock as of the Centre record date, you may also cast your vote in person at the Centre special meeting. If you plan to attend the Centre special meeting, you must hold your shares in your own name or have a letter from the record holder of your shares confirming your ownership.

If you are a beneficial owner (i.e., your shares are held in "street name"), please refer to the instructions provided by your bank, broker or other nominee to see which of the above choices are available to you. Your bank, broker or other nominee cannot vote your shares without instructions from you. Please note that if you are a beneficial owner and wish to vote in person at the Centre special meeting, you must obtain a legal proxy from your bank, broker or other nominee.

#### Q:

#### Do Centre directors and executive officers have interests in the merger that are different from, or in addition to, my interests?
**A:**

Yes. In considering the recommendation of the Centre board of directors with respect to the merger agreement, you should be aware that Centre's directors and executive officers have interests in the merger that are different from, or in addition to, the interests of Centre's shareholders generally. Interests of officers and directors that may be different from or in addition to the interests of Centre's shareholders include, but are not limited to, cash payments and benefits to Centre's executive officers under their employment agreements and supplemental retirement agreements, accelerated vesting of restricted stock units and accelerated payout of certain deferred compensation account balances for Centre's executive officers and current and former directors in connection with a change in control, the receipt of continued indemnification and directors' and officers' insurance coverage under the merger agreement, a new compensation arrangement between Bank First and Steven M. Eldred, and Bank First's agreement to appoint Steven M. Eldred as a director of both Bank First and Bank First, N.A. For a more complete description of these interests, see "The Merger — Interests of Centre's Directors and Executive Officers in the Merger" beginning on page [61](#tIOCD).

#### Q:

#### What if I abstain from voting, fail to authorize a proxy or fail to vote in person?
**A:**

If you mark "**ABSTAIN**" on your proxy with respect to the Centre merger proposal, fail to authorize a proxy or fail to vote in person at the Centre special meeting, or fail to instruct your bank, broker or other nominee how to vote, it will have the same effect as a vote "**AGAINST**" the Centre merger proposal and no effect on the Centre adjournment proposal. If you sign your proxy but do not indicate your vote, your proxy will be voted "**FOR**" each proposal.

#### Q:

#### What will happen if I return my proxy card without indicating how to vote?
**A:**

If you sign and return your proxy card without indicating how to vote on any particular proposal, the shares of Centre common stock represented by your proxy will be voted as recommended by the Centre board of directors.

#### Q:

#### Can I attend the Centre special meeting and vote my shares in person?
**A:**

Yes. All Centre shareholders as of the Centre record date, including shareholders of record and shareholders who hold their shares through any other holder of record, are invited to attend the Centre special meeting. Holders of record of Centre common stock can vote in person at the Centre special meeting. If you are not a shareholder of record, you must obtain a proxy, executed in your favor, from the record holder of your shares, such as a bank, broker or other nominee, to be able to vote in person at the Centre special meeting. If you plan to attend the Centre special meeting, you must hold your shares in your own name or have a letter from the record holder of your shares confirming your ownership. Centre reserves the right to refuse admittance to anyone without proper proof of share ownership or without proper photo identification. The use of cameras, sound recording equipment, communications devices or any similar equipment during the Centre special meeting is prohibited without express written consent of Centre. Whether or not you intend to be present at the Centre special meeting, you are urged to complete, sign, date and return the enclosed proxy card to Centre in the enclosed postage-paid envelope as soon as possible so your vote will be counted if you later decide not to or are unable to attend the Centre special meeting.

#### Q:

#### Can I change my vote?
**A:**

Yes. If you are a holder of record of Centre common stock, you may revoke your proxy or change your vote at any time prior to the Centre special meeting by: (1) delivering written notice of revocation to Centre 1 Bancorp, Inc., 345 East Grand Avenue, Beloit, WI 53511, Attention: Christy M. Farmer, (2) returning a duly executed proxy card bearing a later date than the date with which your original proxy card was dated, or (3) attending the Centre special meeting and voting in person.

------

[**TABLE OF CONTENTS**](#TOC)

Your attendance at the Centre special meeting will not constitute automatic revocation of the proxy unless you deliver your ballot in person at the Centre special meeting or deliver a written revocation to Centre prior to the voting of such proxy. If your shares are held in "street name", you must contact your bank, broker or other nominee and follow its procedures for changing your vote.

#### Q:

#### What are the material U.S. federal income tax consequences of the merger to U.S. holders of shares of Centre common stock?
**A:**

Each of Bank First and Centre expects that the merger will qualify as a "reorganization" within the meaning of Section 368(a) of the Code. Accordingly, a U.S. holder that receives Bank First shares (including fractional Bank First shares deemed received) in exchange for their Centre common stock in the merger generally will not recognize gain or loss, other than with respect to cash received in lieu of fractional Bank First shares. The obligation of Bank First and Centre to complete the merger is conditioned upon the receipt of an opinion of their respective outside legal counsel to the effect that the merger will qualify as a "reorganization" under Section 368(a) of the Code.

For the definition of "U.S. holder" and a more detailed discussion of the material U.S. federal tax consequences of the merger to U.S. holders, see "Material U.S. Federal Income Tax Consequences of the Merger" beginning on page [131](#tMUFI).

 **THE U.S. FEDERAL INCOME TAX CONSEQUENCES DESCRIBED ABOVE MAY NOT APPLY TO ALL HOLDERS OF CENTRE COMMON STOCK. YOUR PARTICULAR TAX CONSEQUENCES WILL DEPEND ON YOUR INDIVIDUAL SITUATION. ACCORDINGLY, WE STRONGLY URGE YOU TO CONSULT YOUR INDEPENDENT TAX ADVISOR FOR A FULL UNDERSTANDING OF THE PARTICULAR TAX CONSEQUENCES OF THE MERGER TO YOU.** 

#### Q :
 **Will Centre be required to submit the Centre merger proposal to its shareholders even if the Centre board of directors has withdrawn, modified or qualified its recommendation?** 

**A:**

Yes. Unless the merger agreement is terminated before the Centre special meeting, Centre is required to submit the Centre merger proposal to its shareholders even if the Centre board of directors has withdrawn or modified its recommendation.

#### Are Centre shareholders entitled to exercise dissenters' rights?
**A:**

Yes. Holders of record of Centre common stock are entitled to exercise dissenters' rights in connection with the merger, provided that such holders comply with the proper procedures of Subchapter XIII of the Wisconsin Business Corporation Law, or WBCL. A copy of Subchapter XIII of the WBCL is attached as <u>Annex B</u> to this proxy statement/prospectus. Holders of Centre common stock who desire to exercise dissenters' rights pursuant to Subchapter XIII of the WBCL are urged to consult a legal advisor before electing or attempting to exercise these rights. The value determined in the appraisal process may be more or less than the value a Centre shareholder would receive in the merger under the terms of the merger agreement. **Failure to strictly comply with the applicable Wisconsin law provisions will result in the loss of the right of appraisal.** For further information, see "The Merger Agreement — Dissenters' Rights" beginning on page [65](#tDIRI).

Pursuant to the merger agreement, the merger may not be completed if dissenters' rights of appraisal are properly asserted with respect to 10% or more of the outstanding shares of Centre common stock.

#### Q :
 **Are there any risks that I should consider in deciding whether to vote for the approval of the Centre merger proposal, or the other proposals to be considered at the Centre special meeting?** 

**A:**

Yes. You should read and carefully consider the risk factors set forth in the section entitled "Risk Factors" beginning on page [30](#tRIFA). You also should read and carefully consider the risk factors of Bank First contained in the documents that are incorporated by reference into this proxy statement/prospectus.

[**TABLE OF CONTENTS**](#TOC)

#### Q:

#### Should I send my Centre stock certificates with my proxy card for the Centre special meeting?
**A:**

No. You should **NOT** send your Centre stock certificates with your proxy. Bank First, through its appointed exchange agent, will send Centre shareholders separate instructions for exchanging Centre stock certificates and Centre common stock held in book-entry form for the merger consideration. You should, however, locate your stock certificates and keep them in a safe place to avoid any delays in receipt of the merger consideration upon completion of the merger.

#### Q:

#### What should I do if I hold my shares of Centre common stock in book-entry form?
**A:**

You are not required to take any specific actions to exchange your shares of Centre common stock if your shares are held in book-entry form. After the completion of the merger, shares of Centre common stock held in book-entry form automatically will be exchanged for the merger consideration, including shares of Bank First common stock in book-entry form, and any cash to be paid in lieu of fractional shares in the merger.

#### Q:

#### What happens if I sell or transfer ownership of shares of Centre common stock after the record date for the Centre special meeting?
**A:**

The Centre record date is earlier than the expected date of completion of the merger. Therefore, if you sell or transfer ownership of your shares of Centre common stock after the Centre record date, but prior to completion of the merger, you will retain the right to vote at the Centre special meeting, but the right to receive the merger consideration will transfer with the shares of Centre common stock. To receive the merger consideration, you must hold your shares of Centre common stock through completion of the merger.

#### Q:

#### Whom may I contact if I cannot locate my Centre stock certificate(s)?
**A:**

If you are unable to locate your original Centre stock certificate(s), you should contact Christy M. Farmer at (608) 313-9036, or Christy.Farmer@bankatfirstnational.com. Generally, merger consideration for lost certificates cannot be delivered except upon the making of an affidavit claiming such certificate to be lost, stolen or destroyed and the posting of a bond in such amount as Bank First or the exchange agent may determine is reasonably necessary as indemnity against any claim that may be made with respect to such lost certificate.

#### Q:

#### What are the conditions to complete the merger?
**A:**

The obligations of Bank First and Centre to complete the merger are subject to the satisfaction or waiver of certain closing conditions contained in the merger agreement, including the receipt of required regulatory approvals, tax opinions and approval of the Centre merger proposal by Centre's shareholders. For more information, see "The Merger Agreement — Conditions to Complete the Merger" beginning on page [85](#tCTCT).

#### Q:

#### When do you expect to complete the merger?
**A:**

Bank First and Centre expect to complete the merger in the first quarter of 2026, subject to customary closing conditions, including regulatory approval and approval by Centre's shareholders. However, neither Bank First nor Centre can assure you when or if the merger will occur.

#### Q:

#### What happens if the merger is not completed?
**A:**

If the merger is not completed, holders of Centre common stock will not receive any consideration for their shares in connection with the merger. Instead, Centre will remain an independent company. If the merger is completed but, for any reason, the bank merger is not completed, it will have no impact on the consideration to be received by holders of Centre common stock.

------

[**TABLE OF CONTENTS**](#TOC)

In addition, if the merger agreement is terminated in certain circumstances, Centre may be required to pay a termination fee. See the section of this proxy statement/prospectus entitled "The Merger Agreement — Termination Fee" beginning on page [87](#tTEFE) for a discussion of the circumstances under which termination fees will be required to be paid.

#### Q:

#### What should I do if I receive more than one set of voting materials?
**A:**

Shareholders may receive more than one set of voting materials, including multiple copies of this proxy statement/prospectus and multiple proxy cards or voting instruction cards. For example, if you hold shares of stock in more than one brokerage account, you will receive a separate voting instruction card for each brokerage account in which you hold such shares. If you are a holder of record of stock and your shares are registered in more than one name, you will receive more than one proxy card. Please complete, sign, date and return each proxy card and voting instruction card that you receive or otherwise follow the voting instructions set forth in this proxy statement/prospectus to ensure that you vote every share of stock that you own.

#### Q:

#### Whom should I call with questions?
**A:**

If you are a Centre shareholder and you have any questions concerning the merger agreement, the merger or this proxy statement/prospectus, would like additional copies of this proxy statement/prospectus or need help voting your shares of Centre common stock, please contact Don O'Day, President, at (608) 363-8007 or Don.Oday@bankatfirstnational.com, or Jerry Ritzert, Chief Financial Officer, at (608) 363-8080 or Jerry.Ritzert@bankatfirstnational.com.

Centre was incorporated in Wisconsin in January 1983 and owns all of the outstanding shares of common stock of The First National Bank and Trust Company, a national banking association headquartered in Beloit, Wisconsin (which we refer to as "First National Bank").

#### The Merger
 *The Merger Agreement (page [70](#tTMA))* 

Bank First and Centre entered into an Agreement and Plan of Merger, dated as of July 17, 2025, which we refer to as the merger agreement. The merger agreement governs the merger. The merger agreement is included in this proxy statement/prospectus as <u>Annex A</u>. All descriptions in this summary and elsewhere in this proxy statement/prospectus of the terms and conditions of the merger are qualified by reference to the merger agreement. Please read the merger agreement carefully for a more complete understanding of the merger.

------

[**TABLE OF CONTENTS**](#TOC)

 *Structure of the Merger (page [70](#tSOTM))* 

Pursuant to the merger agreement, Centre will merge with and into Bank First, with Bank First as the surviving company, which we refer to as the merger. Immediately after the merger, First National Bank, a wholly-owned bank subsidiary of Centre, will merge with and into Bank First's wholly-owned bank subsidiary, Bank First, N.A., with Bank First, N.A. as the surviving bank, which we refer to as the bank merger.

 *The Merger Consideration (page [71](#tMECO))* 

If the merger is completed, each share of Centre common stock issued and outstanding immediately prior to the effective time of the merger will be converted into the right to receive 0.9200 of a share (the "exchange ratio") of Bank First common stock. Each outstanding share of Bank First's common stock will remain outstanding and unaffected by the merger.

Although the number of shares of Bank First common stock that Centre shareholders will receive is fixed, the market value of the merger consideration will fluctuate with the market price of Bank First common stock and will not be known at the time Centre shareholders vote on the merger. Bank First common stock is currently quoted on the Nasdaq Capital Market under the symbol "BFC." On July 17, 2025, the last full trading day before the public announcement of the merger agreement, based on the last reported sale price of Bank First common stock of $125.78 per share, the exchange ratio represented approximately $115.72 in value for each share of Centre common stock to be converted into Bank First common stock. Based on the closing sale price of Bank First common stock of $124.12 per share on September 25, 2025, the latest practicable trading date prior to the printing of this proxy statement/prospectus, the exchange ratio represented approximately $114.19 in value for each share of Centre common stock to be converted into Bank First common stock. We urge you to obtain current market quotations for the price of Bank First common stock (trading symbol "BFC").

Bank First will not issue any fractional shares of Bank First common stock in the merger. Instead, a Bank First shareholder who otherwise would have received a fraction of a share of Bank First common stock will receive an amount in cash (without interest and rounded to the nearest cent) determined by multiplying (1) the per share volume weighted average price of Bank First common stock as reported on the Nasdaq Capital Market during the ten consecutive trading days immediately prior to the fifth trading day prior to closing by (2) the fraction of a share (rounded to the nearest one hundredth of a share) of Bank First common stock to which such shareholder would otherwise be entitled to receive.

The merger consideration is also subject to a downward adjustment based on Centre's tangible book value at closing. If Centre's tangible book value (as calculated per the merger agreement) is less than $83,587,000 (which we refer to as the "minimum Centre tangible book value") at the time of the closing of the merger, then the merger consideration will be adjusted downward by an amount that is reflective of the overall shortfall between the minimum Centre tangible book value and Centre's tangible book value at closing.

Centre may terminate the merger agreement if (i) the average closing price of Bank First common stock over the ten consecutive trading days immediately preceding the date that all regulatory approvals for the merger has been received is less than $110.06, and (ii) the decline in the price of Bank First common stock (as measured by the average closing price divided by $125.78) is more than 12.5% greater than the decline in the Nasdaq Bank Index (as measured by dividing the average closing price of the Nasdaq Bank Index over the ten trading days immediately preceding the date that all regulatory approvals for the merger has been received by $4,535.06); provided, however, that Bank First has the option, but not the obligation, to adjust the exchange ratio to prevent the termination of merger agreement.

 *Treatment of Centre Equity Awards (page [72](#tTOCE))* 

Immediately prior to the effective time of the merger, all outstanding Centre performance-based restricted stock units and Centre time-based restricted stock units granted under a Centre stock plan (with we collectively refer to as "Centre restricted stock") will become fully vested.

------

[**TABLE OF CONTENTS**](#TOC)

At the effective time of the merger, each share of Centre restricted stock that is outstanding prior to the closing of the merger will be cancelled and converted automatically (without any further action on part of the holder thereto) into the right to receive the merger consideration for the applicable number of shares. Payments will be made without interest and subject to tax withholdings.

At the effective time of the merger, each option to purchase shares of Centre common stock, whether vested or unvested, will be cancelled and converted into the right to receive an amount in cash, without interest, equal to the product of (1) the total number of shares of Centre common stock subject to such option and (2) the excess, if any, of the per share volume weighted average price of Bank First common stock as reported on the Nasdaq Capital Market during the ten consecutive trading days immediately prior to the fifth trading day prior to closing over the exercise price per share of Centre common stock under such option, less applicable taxes.

All Centre stock plans and related agreements will terminate at the effective time of the merger, and no further rights to acquire Centre common stock or Bank First common stock will remain outstanding.

 *Procedures for Converting Shares of Centre Common Stock into Merger Consideration (page [72](#tPFCS))* 

Promptly after the effective time of the merger, Bank First's exchange agent will mail to each holder of record of Centre common stock that is converted into the right to receive the merger consideration a letter of transmittal and instructions for the surrender of the holder's Centre stock certificate(s) for the merger consideration (including cash in lieu of any fractional Centre shares), and any dividends or distributions to which such holder is entitled to pursuant to the merger agreement.

Please do not send in your certificates until you receive these instructions.

#### Ancillary Agreements to the Merger Agreement
 *Voting Agreements (page [88](#tVOAG))* 

As a condition to Bank First entering into the merger agreement, all directors and executive officers of Centre and First National Bank who have voting power over shares of Centre common stock entered into voting agreements in the form attached as Exhibit A to the merger agreement attached as <u>Annex A</u> to this proxy statement/prospectus, pursuant to which each such person agreed, among other things, to vote the shares of Centre common stock held of record by such person (1) to approve the merger agreement and the merger (or any adjournment or postponement necessary to solicit additional proxies to approve the merger agreement and the merger) and (2) against any acquisition proposals or any actions that would result in a breach of any covenant, representation or warranty of Centre in the merger agreement.

 *Non-Competition and Non-Disclosure Agreements (page [88](#tNANA))* 

In addition, as a condition to Bank First entering into the merger agreement, each director of Centre and First National Bank entered into non-competition and non-disclosure agreements with Bank First in the form attached as Exhibit C to the merger agreement attached as <u>Annex A</u> to this proxy statement/prospectus, pursuant to which each such person agreed to, among other things, (1) not disclose or use any confidential information or trade secrets of Centre for any purpose for so long as such information remains confidential information or a trade secret, (2) for a period of two years following the closing of the merger, not engage in certain competitive activities with Bank First, including not soliciting employees and customers of Centre, and (3) for a period of two years following the closing of the merger, not serve as a director or management official of another financial institution in the counties in Wisconsin in which First National Bank operates a banking office as of the closing of the merger and each county contiguous to each of such counties.

At the time of the execution of the merger agreement, each director and executive officer of Centre and First National Bank executed a letter agreement with Bank First in the form attached as Exhibit D to the merger agreement attached as <u>Annex A</u> to this document, pursuant to which each such director and executive officer released and discharged, effective upon the consummation of the merger, Centre and its subsidiaries, their respective directors and officers (in their capacities as such), and their respective successors and assigns (including Bank First and Bank First, N.A.), from any and all liabilities or claims that the director or executive officer has or claims to have as of the effective time of the merger, with certain exceptions.

#### Risk Factors (page 30)
Before submitting your proxy or voting at the Centre special meeting, you should carefully consider all the information contained in or incorporated by reference into this proxy statement/prospectus in deciding how to vote for the proposals presented in this proxy statement/prospectus.

#### The Centre Special Meeting (page 39)
The special meeting of Centre shareholders will be located at 345 E Grand Ave., Beloit, Wisconsin 53511, on November 13, 2025, at 9:00 a.m., Central Time. At the Centre special meeting, Centre shareholders will be asked to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • approve the Centre merger proposal; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • approve the Centre adjournment proposal.

Only holders of record at the close of business on September 26, 2025, the Centre record date, will be entitled to vote at the Centre special meeting. Each outstanding share of Centre common stock is entitled to one vote on each proposal to be considered at the Centre special meeting. As of the Centre record date, there were 1,478,333 shares of Centre common stock entitled to vote at the Centre special meeting. All directors and executive officers of Centre and First National Bank have entered into voting agreements with Bank First, pursuant to which they have agreed, solely in their capacity as Centre shareholders, to vote all of their shares of Centre common stock in favor of the proposals to be presented at the Centre special meeting. As of the Centre record date, the directors and executive officers who are parties to the voting agreements owned and were entitled to vote an aggregate of approximately 291,382 shares of Centre common stock, which represented approximately 19.71% of the shares of Centre common stock outstanding on that date. As of the Centre record date, Bank First did not own or have the right to vote any of the outstanding shares of Centre common stock.

To approve the Centre merger proposal, the holders of at least a majority of the outstanding shares of Centre common stock entitled to vote on the proposal must vote in favor of the proposal. Your failure to submit a proxy or vote in person at the Centre special meeting, failure to instruct your bank, broker or other nominee how to vote, or abstention with respect to the Centre merger proposal will have the same effect as a vote against the Centre merger proposal.

The Centre adjournment proposal requires the votes cast favoring the action to exceed the votes cast opposing the action.

If you mark "**ABSTAIN**" on your proxy with respect to the Centre merger proposal, fail to authorize a proxy and fail to vote in person at the Centre special meeting, or fail to instruct your bank, broker or other nominee how to vote, it will have the same effect as a vote "**AGAINST**" the Centre merger proposal and no effect on the Centre adjournment proposal. If you sign your proxy but do not indicate your vote, your proxy will be voted "**FOR**" each proposal.

#### Recommendation of the Centre Board of Directors (page 40)
Centre's board of directors has determined that the merger, the merger agreement and the transactions contemplated by the merger agreement are advisable and in the best interests of Centre and its shareholders and has unanimously approved the merger, the merger agreement and the transactions contemplated by the merger agreement. **Centre's board of directors unanimously recommends that Centre shareholders vote "FOR" the Centre merger proposal and "FOR" the Centre adjournment proposal (if necessary or appropriate)**. For the factors considered by Centre's board of directors in reaching its decision to approve the merger, see "The Merger — Centre's Reasons for the Merger; Recommendation of the Centre Board of Directors."

#### Board Composition and Management of Bank First after the Merger (page 61)
Each of the officers and directors of Bank First immediately prior to the effective time of the merger will be the officers and directors of the surviving company from and after the effective time of the merger, until their respective successors have been duly elected, appointed or qualified or until their earlier death, resignation or removal in accordance with the articles of incorporation and bylaws of Bank First, *provided, however*, that Bank First and Bank First, N.A. will each increase the size of its respective board of directors by one, and Steven M. Eldred will be appointed as a director of Bank First and Bank First, N.A.

Additionally, Bank First will consider appointing one additional member of Centre's board of directors (the "Centre director") to the Bank First board after consulting with Centre. If Bank First decides to proceed with such appointment, it will take all necessary steps to increase the size of its board of directors and appoint the Centre director as of the effective time of the merger. This appointment is subject to the Centre director meeting Bank First's director qualifications, complying with Bank First's corporate governance policies, and qualifying as an "independent director" under Nasdaq rules.

#### Interests of Centre's Directors and Executive Officers in the Merger (page 61)
Centre shareholders should be aware that Centre's directors and executive officers have interests in the merger and have arrangements that are different from, or in addition to, those of Centre shareholders generally. These interests and arrangements may create potential conflicts of interest. Centre's board of directors was aware of these interests and considered these interests, among other matters, in adopting and approving the merger agreement and the transactions contemplated by the merger agreement, including the merger, and in recommending that Centre common shareholders vote in favor of the Centre merger proposal.

These interests include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the executive officers of Centre have employment agreements with Centre that provide for cash payments and other benefits in the event of a qualifying termination of employment in connection with a change in control;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Mr. Eldred has a supplemental retirement agreement with Centre that provides for accelerated benefits in connection with a change in control;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Mr. O'Day participates in a supplemental life insurance benefit that provides for accelerated and enhanced benefits in connection with a change in control;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • The executive officers and current and former directors of Centre and First National Bank will be entitled to additional benefits in connection with the change in control relating to accelerated vesting of restricted stock units, accelerated payout of certain deferred compensation account balances, and the right to continued indemnification and directors' and officers' liability insurance coverage;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Mr. Eldred will be appointed as a director of Bank First and Bank First, N.A.; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Mr. Eldred intends to enter into a consulting agreement with Bank First upon the closing of the merger, under which Mr. Eldred will receive compensation from Bank First for a period of two years, in exchange for providing ongoing services related to the transition of First National Bank's and/or Centre's clients, employees, impacted communities, vendors, and other interested parties; successful system conversions; and other matters to ensure smooth transition of ownership to Bank First.

[**TABLE OF CONTENTS**](#TOC)

For a more complete description of these interests, see "The Merger — Interests of Centre's Directors and Executive Officers in the Merger" beginning on page [61](#tIOCD) and "The Merger Agreement — Indemnification and Directors' and Officers' Insurance" beginning on page [82](#tIADA).

#### Dissenters' Rights (page 65)
If the merger is completed, Centre shareholders who do not vote for the merger and who follow certain procedures as required by Wisconsin law and described in this proxy statement/prospectus will be entitled to exercise dissenters' rights and receive the "fair value" of their shares in cash under Wisconsin law. If you assert and perfect your dissenters' rights, you will not receive any merger consideration but will be entitled to receive the "fair value" of your shares of stock in cash as determined in accordance with Wisconsin law. The "fair value" of your shares may be more or less than the consideration to be paid in the merger. <u>Annex B</u> includes the relevant provisions of Wisconsin law regarding these rights. See "The Merger — Dissenters' Rights" beginning on page [65](#tDIRI) of this proxy statement/prospectus. **Centre shareholders holding Centre common stock who desire to exercise dissenters' rights pursuant to Subchapter XIII of the WBCL are urged to consult a legal advisor before electing or attempting to exercise these rights.** 

Centre shareholders should be aware that cash paid to dissenting shareholders in satisfaction of the fair value of their shares of Centre common stock will result in the recognition of any gain or loss realized for U.S. federal income tax purposes.

For further information, see "The Merger — Dissenters' Rights" beginning on page [65](#tDIRI).

Pursuant to the merger agreement, Bank First's board of directors may terminate the merger agreement and abandon the merger if dissenters' rights of appraisal are properly asserted with respect to more than 10% of the outstanding shares of Centre common stock.

#### Conditions to Complete the Merger (page 85)
Currently, Bank First and Centre expect to complete the merger in the first quarter of 2026, subject to customary closing conditions, including regulatory approval and approval by Centre's shareholders. As more fully described in this proxy statement/prospectus and in the merger agreement, the completion of the merger depends on a number of conditions being satisfied or, where legally permissible, waived. These conditions include, among others:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • approval of the merger agreement by the holders of at least a majority of the outstanding shares of Centre common stock entitled to vote at the Centre special meeting;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the receipt of required regulatory approvals or waivers, including the approval or waiver from the Federal Reserve and the approvals of the OCC and WDFI, which are necessary to consummate the merger and the expiration of all statutory waiting periods without the imposition of any burdensome condition;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the absence of any injunction, order or decree restraining, enjoining or otherwise prohibiting the merger or any of the other transactions contemplated by the merger agreement or making the completion of the merger illegal;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the effectiveness under the Securities Act of 1933, as amended (the "Securities Act") of the registration statement on Form S-4 of which this proxy statement/prospectus is a part, and the absence of the issuance of a stop order or the initiation or threat by the SEC of proceedings for that purpose;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the receipt of all required consents and approvals identified by the merger agreement;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • each party's receipt of a tax opinion from its respective outside legal counsel, dated the closing date of the merger, to the effect that the merger qualifies as a "reorganization" within the meaning of Section 368(a) of the Code;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the Bank Plan of Merger and Merger Agreement in the form attached as Exhibit B to the merger agreement attached as <u>Annex A</u> to this document being executed and delivered;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the absence of 10% or more of the outstanding shares of Centre's common stock exercising their dissenters' rights;

------

[**TABLE OF CONTENTS**](#TOC)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the absence of any material adverse effect in the financial condition, business or results of operations of Centre, First National Bank, Bank First or Bank First, N.A.;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the shares of Bank First common stock being approved for listing on the Nasdaq Capital Market;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the continued accuracy of the representations and warranties made by the parties in the merger agreement; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the performance by each party of its respective obligations under the merger agreement.

Neither Centre nor Bank First can provide assurance as to when or if all of the conditions to the merger can or will be satisfied or waived by the appropriate party, or that the merger will be completed. For more information see "The Merger Agreement — Conditions to Complete the Merger."

#### Regulatory Approvals Required for the Merger (page 63)
Both Bank First and Centre have agreed to use their reasonable best efforts to obtain all regulatory approvals (or waivers) required or advisable to complete the transactions contemplated by the merger agreement. These approvals include, among others, approval from the Board of Governors of the Federal Reserve System, or the Federal Reserve Board, the Office of the Comptroller of the Currency, or the OCC, the Wisconsin Department of Financial Institutions, or the WDFI, and various securities and other regulatory authorities. The U.S. Department of Justice may also review the impact of the merger on competition. Bank First and Centre have submitted all applications, waiver requests and notifications to obtain the required regulatory approvals. Although neither Bank First nor Centre knows of any reason why these regulatory approvals cannot be obtained, Bank First and Centre cannot be certain when or if they will be obtained, as the length of the review process may vary based on, among other things, requests by regulators for additional information or materials.

#### No Solicitation (page 83)
Under the merger agreement, Centre has agreed that it will not, and will cause its subsidiaries and representatives not to, directly or indirectly, (1) initiate, solicit, induce or knowingly encourage, or take any action to facilitate the making of, any inquiry, offer or proposal which constitutes, or could reasonably be expected to lead to, an acquisition proposal, (2) participate in any discussions or negotiations regarding any acquisition proposal or furnish, or otherwise afford access, to any person (other than Bank First) any information or data with respect to Centre or any of its subsidiaries or otherwise relating to an acquisition proposal, (3) release any person from, waive any provisions of, or fail to enforce any confidentiality agreement or standstill agreement to which Centre is a party, or (4) enter into any agreement, confidentiality agreement, agreement in principle or letter of intent with respect to any acquisition proposal or approve or resolve to approve any acquisition proposal or any agreement, agreement in principle or letter of intent relating to an acquisition proposal.

However, prior to obtaining Centre's required shareholder approval, Centre may, under certain specified circumstances, participate in negotiations or discussions with any third party making an acquisition proposal and provide confidential information to such third party (subject to a confidentiality agreement). Centre must notify Bank First promptly (but in no event later than 24 hours) after the receipt of such acquisition proposal.

Additionally, prior to obtaining Centre's required shareholder approval, Centre may, under certain specified circumstances, withdraw its recommendation to its shareholders with respect to the merger and/or terminate the merger agreement in order to enter into an acquisition agreement with respect to a superior acquisition proposal if it determines in good faith, after consultation with and having considered the advice of outside legal counsel and financial advisors, that such acquisition proposal is a superior proposal and that the failure to take such actions would cause it to violate its fiduciary duties to Centre's shareholders under applicable law. However, Centre cannot take any of those actions in response to a superior proposal unless it provides Bank First with a five business day period to negotiate in good faith to enable Bank First to adjust the terms and conditions of the merger agreement such that it would cause the superior proposal to no longer constitute a superior proposal.

[**TABLE OF CONTENTS**](#TOC)

#### Termination of the Merger Agreement (page 86)
The merger agreement can be terminated at any time prior to completion of the merger by mutual consent, or by either party in the following circumstances:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • if the merger is not consummated on or before April 30, 2026, subject to automatic extension to May 31, 2026 if the only outstanding condition to closing is the receipt of regulatory approvals;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • if any regulatory approval required for consummation of the transactions contemplated by the merger agreement has been denied by final non-appealable action by the relevant governmental authority or any application for such regulatory approval shall have been permanently withdrawn at the request of a governmental authority;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • in the event that approval by the shareholders of Centre is not obtained at a meeting at which a vote was taken; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • in the event of a material breach by the other party of any representation, warranty or covenant contained in the merger agreement and such breach is not cured within 30 days.

In addition, Bank First may terminate the merger agreement in the following circumstances:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • if Centre fails to comply in all material respects with its obligations pursuant to the non-solicitation covenants;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • if Centre withdraws, qualifies, amends, modifies or withholds its recommendation to its shareholders to approve the merger and the merger agreement, or makes any statement, filing or release, in connection with the shareholder meeting or otherwise, inconsistent with its recommendation (it being understood that taking a neutral position or no position with respect to an acquisition proposal shall be considered an adverse modification of its recommendation);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • if Centre materially breaches its obligation to call, give notice of, and commence a meeting of shareholders to vote on the merger agreement;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • if Centre approves or recommends an acquisition proposal (other than the merger agreement proposal);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • if Centre fails to publicly recommend against a publicly announced acquisition proposal within three business days of being requested to do so by Bank First or fails to publicly reconfirm its recommendation to its shareholders within three business days of being requested to do so by Bank First; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • if Centre resolves or otherwise determines to take, or announces an intention to take, any of the foregoing actions.

In addition, Centre may terminate the merger agreement if:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Centre's board of directors determines to enter into a definitive agreement with respect to a superior proposal in accordance with the terms of the merger agreement but only if Centre pays to Bank First a $5,300,000 termination fee; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (i) the average closing price of Bank First common stock over the ten consecutive trading days immediately preceding the date that all regulatory approvals for the merger has been received is less than $110.06, and (ii) the decline in the price of Bank First common stock (as measured by the average closing price divided by $125.78) is more than 12.5% greater than the decline in the Nasdaq Bank Index (as measured by dividing the average closing price of the Nasdaq Bank Index over the ten trading days immediately preceding the date that all regulatory approvals for the merger has been received by $4,535.06); *provided, however*, that Bank First has the option, but not the obligation, to adjust the exchange ratio to prevent the termination of merger agreement.

------

[**TABLE OF CONTENTS**](#TOC)

#### Termination Fee (page 87)
If the merger agreement is terminated under certain circumstances, including circumstances involving an alternative acquisition proposal or a change in recommendation by Centre's board of directors, Centre may be required to pay Bank First a termination fee equal to $5,300,000. This termination fee could discourage other companies from seeking to acquire or merge with Centre.

#### Expenses (page 87)
Each party will bear all of its respective expenses incurred in connection with the merger and the transactions contemplated by the merger agreement.

#### Material U.S. Federal Income Tax Consequences of the Merger (page 131)
The merger is expected to qualify as a "reorganization" within the meaning of Section 368(a) of the Code, and it is a condition to the respective obligations of Bank First and Centre to complete the merger that each of Bank First and Centre receives a tax opinion from its respective outside legal counsel, dated as of the closing date of the merger, to that effect. These opinions, however, will not bind the Internal Revenue Service ("IRS") or the courts, which could take a contrary view. Based upon the qualification of the merger as a reorganization under the Code, holders of Centre common stock who exchange their shares of Centre common stock for shares of Bank First common stock generally will not recognize gain or loss with respect to the receipt of Bank First common stock in the merger, except with respect to cash received in lieu of fractional shares of Bank First common stock.

 *The U.S. federal income tax consequences described above may not apply to all holders of Centre common stock. Your tax consequences will depend on your individual situation. Accordingly, Bank First and Centre strongly urge you to consult your own independent tax advisor for a full understanding of the particular tax consequences of the merger to you.* 

#### Accounting Treatment (page 131)
Bank First will account for the merger under the acquisition method of accounting for business combinations under U.S. generally accepted accounting principles, or GAAP.

#### Comparison of Shareholders' Rights (see page 118)
The rights of holders of Centre common stock are governed by Wisconsin law, as well as Centre's Restated Articles of Incorporation (which we refer to as the Centre Articles), and Centre's Amended and Restated Bylaws (which we refer to as the Centre Bylaws). After completion of the merger, the rights of former Centre shareholders will be governed by Wisconsin law and by Bank First's Restated Articles of Incorporation (which we refer to as Bank First Articles), and Bank First's Amended and Restated Bylaws (which we refer to as Bank First Bylaws).

Material differences between the rights of shareholders of Centre and shareholders of Bank First include the process for determining the size of the board of directors, director independence requirements, the classification and term of directors, the ability of shareholders to call special meetings, and the procedures for shareholder proposals and advance notice requirements. The material differences between the organizational documents and the rights of shareholders of Centre and shareholders of Bank First are explained in more detail under the section "Comparison of Shareholders' Rights" beginning on page [118](#tCOSR).

#### Opinion of Centre's Financial Advisor (page 51)
On July 17, 2025, Hovde Group, LLC ("Hovde") rendered an opinion to the Centre board of directors to the effect that, as of such date and subject to the matters, assumptions and limitations set forth in the opinion and pursuant to the terms of the merger agreement, the merger consideration is fair, from a financial point of view, to the holders of shares of Centre common stock. The full text of the written opinion of Hovde is attached as <u>Annex C</u> to this document. Centre shareholders should read the entire opinion for a discussion of, among other things, the assumptions made, procedures followed, matters considered and qualifications and limitations on the review undertaken by Hovde in rendering its opinion.

------

[**TABLE OF CONTENTS**](#TOC)

The opinion of Hovde is addressed to the Centre board of directors and is directed only to the fairness, from a financial point of view, of the price to be received by the holders of Centre common stock and does not constitute a recommendation to any Centre shareholder as to how such shareholder should vote with respect to the merger or any other matter at the Centre special meeting.

For further information, please see the section entitled "The Merger — Opinion of Centre's Financial Advisor" beginning on page [51](#tOOCF).

#### Closing and Effective Time of the Merger (see page 70)
The closing date is currently expected to occur in the first quarter of 2026, subject to customary closing conditions, including regulatory approval and approval by Centre's shareholders. Simultaneously with the closing of the merger, Bank First will file articles of merger with the WDFI. The merger will become effective at the later of the time the articles of merger are filed or such other time as may be specified in the articles of merger. Neither Bank First nor Centre can predict, however, the actual date on which the merger will be completed because it is subject to factors beyond each company's control, including whether or when the required regulatory approvals and Centre's shareholder approval will be received.

#### Unaudited Comparative Per Share Data (see page 25)
Bank First common stock is listed on the Nasdaq Capital Market under the symbol "BFC." Centre common stock is not listed on an exchange and is not actively traded. The following table sets forth the closing sale prices of Bank First common stock as reported on the Nasdaq Capital Market on July 17, 2025, the last full trading day before the public announcement of the merger agreement, and on September 25, 2025, the latest practicable trading date before the date of this proxy statement/prospectus.

Under the merger agreement, Centre is prohibited from paying any dividend or distribution to its shareholders before the effective time of the merger, other than dividends paid in the ordinary course of business and consistent with past practices, without the prior written consent of Bank First. Centre's ability to pay dividends is also subject to state and federal laws and regulations.

#### UNAUDITED PRO FORMA COMBINED CONSOLIDATED FINANCIAL STATEMENTS
The following unaudited pro forma combined financial information is presented to illustrate the estimated effects of the merger based on the historical financial statements and accounting records of Bank First and Centre after giving effect to the merger, including the merger-related pro forma adjustments as described in the notes below. The unaudited pro forma combined consolidated financial information has been prepared using the acquisition method of accounting. Under this method, Centre's assets and liabilities as of the date of the acquisition will be recorded at their respective fair values and added to those of Bank First. Any difference between the purchase price for Centre and the fair value of the identifiable net assets acquired (including core deposit intangibles) will be recorded as goodwill. The goodwill resulting from the acquisition will not be amortized to expense but instead will be reviewed for impairment at least annually. Any core deposit intangible and other intangible assets with estimated useful lives to be recorded by Bank First in connection with the acquisition will be amortized to expense over their estimated useful lives. The financial statements of Bank First issued after the acquisition will reflect the results attributable to the acquired operations of Centre beginning on the date of completion of the acquisition.

Pursuant to the merger agreement, each share of Centre common stock issued and outstanding immediately prior to the effective time of the merger will be converted into the right to receive 0.9200 shares of Bank First common stock. The unaudited pro forma combined consolidated financial information set forth below and the explanatory notes that follow are based upon assumptions that 1,476,333 shares of Centre common stock (the number of shares outstanding as of the date the merger agreement was signed) are outstanding on the closing date of the merger.

The unaudited pro forma combined consolidated balance sheet combines the historical consolidated balance sheets of Bank First and Centre, giving effect to the merger as if it had been consummated on June 30, 2025. The unaudited pro forma combined consolidated statements of income for the year ended December 31, 2024 and the six months ended June 30, 2025 combine the historical consolidated statements of income of Bank First and Centre, giving effect to the merger as if it had been consummated on January 1, 2025.

The unaudited pro forma combined consolidated financial statements give effect to the acquisition of Centre as a business combination under U.S. generally accepted accounting principles ("GAAP"). Accordingly, all assets and liabilities were recorded at estimated fair value. Pro forma adjustments are included only to the extent they are (1) directly attributable to the acquisition, (2) factually supportable and (3) with respect to the unaudited pro forma combined statement of income, expected to have a continuing impact on the combined results. The pro forma adjustments are based on estimates made for the purpose of preparing these pro forma statements and are described in the accompanying notes. Bank First's management believes that the estimates used in these pro forma financial statements are reasonable under the circumstances.

The pro forma adjustments included herein are subject to change as additional information becomes available and additional analyses are performed. The final allocation of the purchase price will be determined after further valuation analyses under GAAP are performed with respect to the fair values of certain tangible and intangible assets and liabilities as of the date of acquisition. The final adjustments may be materially different from the unaudited pro forma adjustments presented herein. In addition, the pro forma income statement information does not include anticipated cost savings or revenue enhancements, which management believes will result from combining certain operating procedures, nor does it include one-time merger-related expenses which will be expensed against income.

Increases or decreases in the estimated fair values of the net assets as compared with the information shown in the unaudited pro forma combined consolidated financial information may change the amount of the purchase price allocated to goodwill and other assets and liabilities and may impact Bank First's consolidated statement of operations due to adjustments in yield and/or amortization of the adjusted assets or liabilities. Any changes to Centre's shareholders' equity, including results of operations from June 30, 2025 through the date the merger is completed will also change the purchase price allocation, which may include the recording of a lower or higher amount of goodwill. The final adjustments may be materially different from the unaudited transaction accounting adjustments presented herein.

------

[**TABLE OF CONTENTS**](#TOC)

The pro forma calculations, shown herein, assume a closing price for Bank First common stock of $117.65, which represents the closing price of Bank First common stock on June 30, 2025.

Bank First anticipates that the acquisition of Centre will provide the combined company with the ability to better serve its customers, reach new customers and reduce operating expenses. In addition, certain subjective estimates have been utilized in determining the pro forma adjustments applied to the historical results of operations of Centre. The pro forma information, while helpful in illustrating the financial characteristics of the combined company under one set of assumptions, does not reflect the benefits of expected cost savings or opportunities to earn additional revenue and, accordingly, does not attempt to predict or suggest future results. It also does not necessarily reflect what the historical results of the combined company would have been had our companies been combined during this period.

The unaudited pro forma condensed combined consolidated financial information has been derived from, and should be read in conjunction with, the historical consolidated financial statements and related notes of Bank First and Centre which are included with this proxy statement/prospectus or incorporated by reference herein.

The unaudited pro forma condensed combined consolidated financial information is qualified by the statements set forth under this caption and should not be considered indicative of the market value of Bank First common stock or the actual or future results of operations of Bank First for any period. Actual results may be materially different than the pro forma information presented.

#### UNAUDITED COMPARATIVE PER SHARE DATA
The following table shows unaudited basic and diluted earnings, cash dividends, and book value per common share data for Bank First and Centre on a historical and pro forma combined basis after giving effect to the acquisition of Centre by Bank First as of and for the twelve months ended December 31, 2024 and the six months ended June 30, 2025. The unaudited pro forma data was derived by combining the historical financial information of Bank First and Centre using the acquisition method of accounting for business combinations, assumes the merger is completed as contemplated and represents a current estimate based on available information of the combined company's results of operations. The unaudited pro forma data and equivalent per share information gives effect to the merger as if the merger had been effective on the dates presented, in the case of the book value data, and as if the transactions had become effective on June 30, 2025, in the case of the earnings per share and dividends declared data. The pro forma adjustments record the assets and liabilities of Centre at their estimated fair values and are subject to adjustment as additional information becomes available and as additional analysis is performed.

The information should be read together with the historical consolidated financial statements of Bank First and Centre and the pro forma condensed combined consolidated financial information, including the notes thereto, which are included elsewhere in this proxy statement/prospectus.

The selected unaudited pro forma information, while helpful in illustrating the financial characteristics of the combined company under a set of assumptions including the effect of the merger, does not reflect the impact of other factors that may result as a consequence of the merger or consider any potential impacts of current market conditions or the merger on revenues, expense efficiencies, asset dispositions, among other factors, nor the impact of possible business model changes. As a result, unaudited pro forma data is presented for illustrative purposes only and does not represent an attempt to predict or suggest future results. Upon completion of the merger, the operating results of Centre will be reflected in the consolidated financial statements of Bank First on a prospective basis.

The per equivalent Centre share data shows the effect of the merger from the perspective of an owner of Centre common stock. The per equivalent Centre share data is based on a per share exchange ratio of 0.9200 of a share of Bank First common stock for each share of Centre common stock.

#### PURCHASE PRICE ALLOCATION
The total estimated purchase price for the purpose of this pro forma financial information is approximately $163 million. The adjustment for shares outstanding, basic, and diluted weighted average common shares outstanding is an amount to adjust the shares to equal the new common shares issued for the transaction. The following is a summary of the fair value of assets acquired and liabilities assumed resulting in goodwill. Goodwill is created when the purchase price consideration exceeds the fair value of the net assets acquired or a bargain purchase gain results when the current fair value of the net assets acquired exceeds the purchase price consideration. For purposes of this analysis as of June 30, 2025, goodwill results from the transaction; however, the final purchase accounting analysis will be performed as of the merger date and amounts therein are subject to change based on operations subsequent to June 30, 2025, as additional information becomes available and as additional analyses are performed.

You should also consider the other information in this proxy statement/prospectus and the other documents incorporated by reference into this proxy statement/prospectus.

#### Risks Related to the Merger
 ***Because of the fixed exchange ratio and the fluctuation of the market price of Bank First common stock, Centre shareholders will not know at the time of the Centre special meeting the market value of the merger consideration they may receive at the effective time of the merger.***

Pursuant to the merger agreement, each share of Centre common stock issued and outstanding immediately prior to the effective time of the merger will be converted into the right to receive 0.9200 of a share of Bank First common stock. The market value of the merger consideration may vary from the market value on the date Bank First and Centre announced the merger, on the date that this proxy statement/prospectus is mailed, on the date of the Centre special meeting and on the date the merger is completed and thereafter due to fluctuations in the market price of Bank First common stock. Any fluctuation in the market price of Bank First common stock after the date of this proxy statement/prospectus will change the value of the shares of Bank First common stock that Centre shareholders may receive. Stock price changes may result from a variety of factors that are beyond the control of Bank First and Centre, including, but not limited to, general market and economic conditions, changes in their respective businesses, operations and prospects and regulatory considerations. Therefore, at the time of the Centre special meeting, Centre shareholders will not know the precise market value of the merger consideration they may receive at the effective time of the merger. Centre shareholders should obtain current sale prices for shares of Bank First common stock before voting their shares at the Centre special meeting.

 ***Because the merger agreement allows for adjustments to the merger consideration, the merger consideration holders of Centre common stock receive in the merger may be materially diminished.***

The merger agreement calls for the consideration payable to holders of shares of Centre common stock in the merger to be reduced if the tangible book value, as defined in the merger agreement, of Centre at closing of the merger is less than $83,587,000. Management of Centre, using information available to it prior to the execution of the merger agreement believed that Centre would be able to achieve the minimum tangible book value prior to closing. However, the calculation of the tangible book value pursuant to the merger agreement involves a number of factors, including, but not limited to, earnings of Centre prior to closing, and other accounting adjustments that may be necessary.

Due to the complexity of the calculation of tangible book value and the uncertainty of the earnings to Centre prior to closing of the merger, there is no guarantee that Centre shareholders will receive the merger consideration. Moreover, there is no requirement that Centre re-solicit shareholder approval if the merger consideration is reduced, and there is no limit on the amount by which it may be reduced. By approving the merger agreement, Centre shareholders are approving the completion of the merger with any downward adjustment in the consideration to be paid to holders of Centre common stock consistent with the terms of the merger agreement.

#### The merger and related transactions are subject to approval by Centre shareholders.
The merger cannot be completed unless the Centre shareholders approve the merger agreement and the merger by the affirmative vote of the holders of at least a majority of the outstanding shares of Centre's common stock entitled to vote at the Centre special meeting.

#### Failure to complete the merger could negatively affect the value of the shares and the future business and financial results of Centre.
If the merger is not completed, the ongoing business of Centre could be adversely affected and Centre will be subject to a variety of risks associated with the failure to complete the merger, including the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Centre being required, under certain circumstances, to pay to Bank First a termination fee equal to $5,300,000;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • substantial costs incurred by Centre in connection with the proposed merger, such as legal, accounting, financial advisor, printing and mailing fees;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the loss of key employees and customers;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the disruption of operations and business;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • deposit attrition, customer loss and revenue loss;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • unexpected problems with costs, operations, personnel, technology and credit;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • diversion of management focus and resources from operational matters and other strategic opportunities while working to implement the merger; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • reputational harm due to the adverse perception of any failure to successfully complete the merger.

If the merger is not completed, these risks could materially affect the business, financial results and the value of Centre common stock.

#### Centre will be subject to business uncertainties and contractual restrictions while the merger is pending.
Uncertainty about the effect of the merger on employees and customers may have an adverse effect on Centre. These uncertainties may impair Centre's ability to attract, retain and motivate strategic personnel until the merger is consummated, and could cause customers and others that deal with Centre to seek to change existing business relationships with Centre. Retention of certain employees by Centre may be challenging while the merger is pending, as certain employees may experience uncertainty about their future roles with Centre or Bank First. If key employees depart because of issues relating to the uncertainty and difficulty of integration or a desire not to remain with Centre or Bank First, Centre's business or the business assumed by Bank First following the merger could be harmed. In addition, Centre has agreed to certain contractual restrictions on the operation of its business prior to closing. See "The Merger Agreement — Covenants and Agreements" for a description of the restrictive covenants applicable to Centre.

 ***The merger agreement contains provisions that may discourage other companies from pursuing, announcing or submitting a business combination proposal to Centre that might result in greater value to Centre shareholders.***

Under the merger agreement, Centre has agreed not to initiate, solicit, induce or knowingly encourage, or take any action to facilitate any alternative business combination transaction or, subject to certain exceptions, participate in discussions or negotiations regarding, or furnish any non-public information relating to, any alternative business combination transaction. See "The Merger Agreement — No Solicitation" on page [83](#tNOSO). The merger agreement also provides for Centre to pay Bank First a termination fee in the amount of $5,300,000 in the event that the merger agreement is terminated for certain reasons. See "The Merger Agreement — Termination Fee" on page [87](#tTEFE). These provisions could discourage a potential competing acquirer that might have an interest in acquiring Centre from considering or making a competing acquisition proposal, even if the potential competing acquirer was prepared to pay consideration with a higher per share cash value than the market value proposed to be received or realized in the merger, or might result in a potential competing acquirer proposing to pay a lower price than it might otherwise have proposed to pay because of the added expense of the termination fee that may become payable in certain circumstances under the merger agreement.

------

[**TABLE OF CONTENTS**](#TOC)

In connection with entering into the merger agreement, each director and executive officer of Centre and First National Bank, in their capacities as Centre shareholders, has entered into voting agreements with Bank First which require, among other things, that the shareholder party thereto vote all of his or her shares of Centre common stock in favor of the merger and the other transactions contemplated by the merger agreement and against alternative transactions and not to, directly or indirectly, assign, sell, transfer or otherwise dispose of his or her shares of Centre common stock, subject to certain exceptions. For further information, please see the section entitled "Ancillary Agreements to the Merger Agreement."

#### The merger agreement contains provisions granting both Bank First and Centre the right to terminate the merger agreement in certain circumstances.
The merger agreement contains certain termination rights, including the right, subject to certain exceptions, of either party to terminate the merger agreement if the merger is not completed on or prior to April 30, 2026 (subject to automatic extension to May 31, 2026 if the only outstanding condition to closing is the receipt of regulatory approvals), and the right of Centre to terminate the merger agreement, subject to certain conditions, to accept a business combination transaction deemed to be superior to the merger by the Centre board of directors. Additionally, Centre may terminate the merger agreement if (i) the average closing price of Bank First common stock over the ten consecutive trading days immediately preceding the date that all regulatory approvals for the merger has been received is less than $110.06, and (ii) the decline in the price of Bank First common stock (as measured by the average closing price divided by $125.78) is more than 12.5% greater than the decline in the Nasdaq Bank Index (as measured by dividing the average closing price of the Nasdaq Bank Index over the ten trading days immediately preceding the date that all regulatory approvals for the merger has been received by $4,535.06); *provided, however*, that Bank First has the option, but not the obligation, to adjust the exchange ratio to prevent the termination of merger agreement.

If the merger is not completed, the ongoing business of Centre could be adversely affected and Centre will be subject to several risks, including the risks described elsewhere in this "Risk Factors" section.

 ***The merger is subject to a number of conditions which, if not satisfied or waived in a timely manner, would delay the merger or adversely impact the companies' ability to complete the transactions contemplated by the merger agreement.***

Bank First and Centre expect the merger to close in the first quarter of 2026, but the acquisition is subject to the satisfaction of a number of closing conditions. Satisfaction of many of these conditions is beyond Bank First's and Centre's control. If these conditions are not satisfied or waived, the merger will not be completed or may be delayed and each of Bank First and Centre may lose some or all of the intended benefits of the merger. Certain of the conditions that remain to be satisfied include, but are not limited to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • approval of the merger agreement by the holders of at least a majority of the outstanding shares of Centre common stock entitled to vote at the Centre special meeting;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the receipt of required regulatory approvals or waivers, including the approval or waiver from the Federal Reserve and the approvals of the OCC and WDFI, which are necessary to consummate the merger and the expiration of all statutory waiting periods without the imposition of any burdensome condition;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the absence of any injunction, order or decree restraining, enjoining or otherwise prohibiting the merger or any of the other transactions contemplated by the merger agreement or making the completion of the merger illegal;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the effectiveness under the Securities Act of the registration statement on Form S-4 of which this proxy statement/prospectus is a part, and the absence of the issuance of a stop order or the initiation or threat by the SEC of proceedings for that purpose;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the receipt of all required consents and approvals identified by the merger agreement;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • each party's receipt of a tax opinion from its respective outside legal counsel, dated the closing date of the merger, to the effect that the merger qualifies as a "reorganization" within the meaning of Section 368(a) of the Code;

------

[**TABLE OF CONTENTS**](#TOC)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the Bank Plan of Merger and Merger Agreement in the form attached as Exhibit B to the merger agreement attached as <u>Annex A</u> to this document being executed and delivered;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the absence of 10% or more of the outstanding shares of Centre's common stock exercising their dissenters' right;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the absence of any material adverse effect in the financial condition, business or results of operations of Centre, First National Bank, Bank First or Bank First, N.A.;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the shares of Bank First common stock being issued as merger consideration being approved for listing on the Nasdaq Capital Market;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the continued accuracy of the representations and warranties made by the parties in the merger agreement; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the performance by each party of its respective obligations under the merger agreement.

As a result, the merger may not close as scheduled or at all. In addition, either Bank First or Centre may terminate the merger agreement under certain circumstances. For additional information regarding the conditions to the merger, see "The Merger Agreement — Conditions to Complete the Merger" beginning on page [85](#tCTCT).

#### Bank First and Centre may waive one or more of the conditions to the merger without re-soliciting shareholder approval for the merger.
Each of the conditions to the obligations of Bank First and Centre to complete the merger may be waived, in whole or in part, to the extent permitted by applicable law, by agreement of Bank First and Centre if the condition is a condition to both parties' obligation to complete the merger, or by the party for which such condition is a condition of its obligation to complete the merger. Similarly, Bank First may agree to certain modifications to the items included in the calculation of the Centre tangible book value. The boards of directors of Bank First and Centre may evaluate the materiality of any such waiver to determine whether amendment of this proxy statement/prospectus and re-solicitation of proxies are necessary. Bank First and Centre, however, generally do not expect any such waiver to be significant enough to require re-solicitation of Centre shareholders. If any such waiver is not determined to be significant enough to require re-solicitation of Centre shareholders, the companies will have the discretion to complete the merger without seeking further Centre shareholder approval.

 ***Regulatory approvals may not be received, may take longer than expected or impose conditions that are not presently anticipated or are adverse to Bank First or Centre.***

Before the transactions contemplated by the merger agreement may be completed, various approvals or consents must be obtained from various federal and state governmental entities, which include the Federal Reserve Board, the OCC, the WDFI, and other securities and regulatory authorities. These governmental entities may request additional information or materials regarding the regulatory applications and notices submitted by Bank First and Centre or may impose conditions on the granting of such approvals. Such conditions or changes and the process of obtaining regulatory approvals could have the effect of delaying the completion of the merger or of imposing additional costs or limitations on the combined company following the merger. The regulatory approvals may not be received at all, may not be received in a timely fashion, and may contain conditions on the completion of the merger that are not anticipated or cannot be met. There can be no assurance as to whether these and other regulatory approvals will be received, the timing of those approvals, or whether any conditions will be imposed. In addition, neither party is obligated to complete the merger if the regulatory approvals received in connection with the completion of the merger impose certain burdensome conditions on Bank First or Centre. See "The Merger — Regulatory Approvals Required for the Merger" on page [63](#tRARF).

------

[**TABLE OF CONTENTS**](#TOC)

 ***The directors and executive officers of Centre have interests in seeing the merger completed that are different from, or in addition to, those of the other Centre shareholders.***

The directors and executive officers of Centre have arrangements that provide them with interests in the merger that are different from, or in addition to, those of the shareholders of Centre generally. These interests and arrangements may create potential conflicts of interest and may influence or may have influenced the directors and executive officers of Centre to support or approve the merger and the merger agreement. See "The Merger — Interests of Centre Directors and Executive Officers in the Merger" beginning on page [61](#tIOCD).

 ***The fairness opinion of Centre's financial advisor will not reflect changes in circumstances between the date of the opinion and the completion of the merger.***

Centre's board of directors received an opinion from its financial advisor to address the fairness of the merger consideration, from a financial point of view, to the holders of Centre's common stock as of July 17, 2025. Subsequent changes in the operation and prospects of Bank First or Centre, general market and economic conditions and other factors that may be beyond the control of Bank First or Centre, and on which Centre's financial advisor's opinion was based, may significantly alter the value of Bank First or the price of the shares of Bank First common stock by the time the merger is completed. Because Centre does not anticipate asking its advisor to update its opinion, the opinion will not address the fairness of the merger consideration from a financial point of view at the time the merger is completed, or as of any other date other than the date of such opinion. For a description of the opinion that Centre received from its financial advisor, please refer to the sections entitled "The Merger — Opinion of Centre's Financial Advisor" beginning on page [51](#tOOCF).

#### Centre shareholders who exercise dissenters' rights may receive less than the value of the merger consideration.
Centre shareholders who properly exercise dissenters' rights under applicable law may receive a cash payment for their shares based on a judicial determination of fair value. This amount may be less than the value of the merger consideration they would otherwise receive under the merger agreement. See "The Merger — Dissenters' Rights" for more information.

#### The merger may be completed even if Bank First or Centre experiences adverse changes in its business.
In general, either Bank First or Centre may refuse to complete the merger if the other party suffers a material adverse effect on its business prior to the closing of the merger. However, certain types of changes or occurrences with respect to Bank First or Centre would not prevent the merger from going forward, even if the change or occurrence would have adverse effects on Bank First or Centre, including the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • changes in laws and regulations affecting financial institutions and their holding companies generally, or interpretations thereof by courts or governmental entities, if such changes do not have a disproportionate impact on the affected company;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • changes in GAAP or regulatory accounting requirements generally applicable to financial institutions and their holding companies, if such changes do not have a disproportionate impact on the affected company;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • changes in global, national or regional political conditions including the outbreak of war or acts of terrorism, or in economic or market conditions affecting the financial services industry generally, if such changes do not have a disproportionate impact on the affected company;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • changes or effects from the announcement of the merger agreement and the transactions contemplated thereby, and compliance by the parties with the merger agreement on the business, financial condition or results of operations of the parties;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • any failure by Centre or Bank First to meet any internal or published industry analyst projections or forecasts or estimates of revenues or earnings for any period (but not including the underlying causes thereof);

------

[**TABLE OF CONTENTS**](#TOC)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • changes in the trading price or trading volume of Bank First common stock (but not including the underlying causes thereof unless otherwise specifically excluded); however, Centre may terminate the merger agreement if (i) the average closing price of Bank First common stock during a specified period prior to closing is less than $110.06 and (ii) Bank First common stock underperforms the Nasdaq Bank Index by more than 12.5%, unless Bank First elects to make a compensating adjustment to the exchange ratio; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the impact of the merger agreement and the transactions contemplated thereby on relationships with customers or employees, including the loss of personnel subsequent to the date of the merger agreement.

 ***Litigation in transactions of this type are sometimes filed against the board of directors of either party that could prevent or delay the completion of the merger or result in the payment of damages following completion of the merger.***

In connection with the merger, it is possible that Centre shareholders may file putative class action lawsuits against the boards of directors of Bank First and/or Centre. Among other remedies, these shareholders could seek to enjoin the merger. The outcome of any such litigation would be uncertain. If a dismissal is not granted or a settlement is not reached, such potential lawsuits could prevent or delay completion of the merger and result in substantial costs to Bank First and Centre. The defense or settlement of any lawsuit or claim that remains unresolved at the time the merger is consummated may adversely affect the combined company's business, financial condition, results of operations, cash flows and market price.

#### Risks Related to the Combined Company Following the Merger

#### The combined company expects to incur substantial expenses related to the merger.
The combined company expects to incur substantial expenses in connection with completing the merger and integrating the business and operations of Centre and Bank First. Although Bank First and Centre have assumed that a certain level of transaction and integration expenses would be incurred, there are a number of factors beyond their control that could affect the total amount or the timing of their integration expenses. Many of the expenses that will be incurred, by their nature, are difficult to estimate accurately at the present time. As a result, the transaction and integration expenses associated with the merger could, particularly in the near term, exceed the savings that the combined company expects to achieve from the integration of the businesses following the completion of the merger.

 ***Following the merger, the combined company may be unable to integrate Centre's business with Bank First successfully and realize the anticipated synergies and other benefits of the merger or do so within the anticipated timeframe.***

The merger involves the combination of two companies that currently operate as independent companies, as well as the companies' subsidiaries. Although the combined company is expected to benefit from certain synergies, including cost savings, the combined company may encounter potential difficulties in the integration process, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the inability to successfully combine Centre's business with Bank First in a manner that permits the combined company to achieve the cost savings anticipated to result from the merger, which would result in the anticipated benefits of the merger not being realized in the timeframe currently anticipated or at all;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the risk of not realizing all of the anticipated operational efficiencies or other anticipated strategic and financial benefits of the merger within the expected timeframe or at all;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • potential unknown liabilities and unforeseen increased expenses, delays or regulatory conditions associated with the merger; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • performance shortfalls as a result of the diversion of management's attention caused by completing the merger and integrating the companies' operations.

------

[**TABLE OF CONTENTS**](#TOC)

For all these reasons, you should be aware that it is possible that the integration process could result in the distraction of the combined company's management, the disruption of the combined company's ongoing business or inconsistencies in the combined company's operations, any of which could adversely affect the ability of the combined company to maintain relationships with customers and employees or to achieve the anticipated benefits of the merger, or could otherwise adversely affect the business and financial results of the combined company.

#### The unaudited pro forma financial information included in this proxy statement/prospectus is illustrative only and may not reflect actual results.
Any pro forma financial statements presented are based on preliminary estimates and assumptions. The actual financial condition and results of operations of the combined company may differ materially from those shown in the pro forma financials due to changes in asset valuations, integration costs, or unforeseen liabilities. These differences could affect investor expectations and the market valuation of the combined company.

#### Following the merger, the combined company may be unable to retain key employees.
The success of the combined company after the merger will depend in part upon its ability to retain key employees. However, key employees may depart either before or after the merger because of issues relating to the uncertainty and difficulty of integration or a desire not to remain with the combined company following the merger. Accordingly, no assurance can be given that Centre or Bank First or, following the merger, the combined company will be able to retain key employees.

 ***Centre shareholders will experience a reduction in percentage ownership and voting power of their shares as a result of the merger and will have less influence on the management and policies of Bank First than they had on Centre before the merger.***

Centre shareholders will have a much smaller percentage ownership interest and effective voting power in Bank First compared to their ownership interest and voting power in Centre prior to the merger. Consequently, Centre shareholders will have significantly less influence on the management and policies of Bank First after the merger than they now have on the management and policies of Centre. If the merger is consummated, current Centre shareholders will own approximately 12.3% of the combined company based upon the number of Bank First shares outstanding as of September 22, 2025. Accordingly, former Centre shareholders will own less than the outstanding voting stock of the combined company than current Bank First shareholders and would, as a result, be outvoted by current Bank First shareholders if such current Bank First shareholders voted together as a group.

#### Sales of Bank First common stock by Centre shareholders following the merger could negatively impact the stock price.
Shares of Bank First common stock issued to Centre shareholders in the merger will be freely tradable. If a significant number of Centre shareholders choose to sell their shares shortly after the merger, this could create downward pressure on the market price of Bank First common stock. Such sales may also make it more difficult for Bank First to raise capital through equity offerings in the future.

#### Future capital needs could result in dilution of shareholder investment.
Bank First's board of directors may determine from time to time there is a need to obtain additional capital through the issuance of additional shares of its common stock or other securities. These issuances would dilute the ownership interests of its shareholders and may dilute the per share book value of Bank First common stock. New investors may also have rights, preferences and privileges senior to Bank First's shareholders which may adversely impact its shareholders.

------

[**TABLE OF CONTENTS**](#TOC)

#### Risks Related to an Investment in the Combined Company's Common Stock
 ***The market price of the shares of common stock of the combined company may be affected by factors different from those affecting the price of shares of Bank First common stock before the merger.***

The results of operations of the combined company, as well as the market price of shares of the common stock of the combined company after the merger, may be affected by factors in addition to those currently affecting Bank First's or Centre's results of operations and the market prices of shares of Bank First common stock. Accordingly, the historical financial results of Bank First and Centre and the historical market prices of shares of Bank First common stock may not be indicative of these matters for the combined company after the merger. For a discussion of the businesses of Bank First and Centre and certain risks to consider in connection with evaluating the proposals to be considered at the Centre special meeting, see the documents incorporated by reference by Bank First into this proxy statement/prospectus referred to under "Where You Can Find More Information" beginning on page [135](#tWYCF).

#### The market price of the combined company's common stock may decline as a result of the merger.
The market price of the combined company's common stock may decline as a result of the merger if the combined company does not achieve the perceived benefits of the merger or the effect of the merger on the combined company's financial results is not consistent with the expectations of financial or industry analysts. In addition, upon completion of the merger, Bank First and Centre shareholders will own interests in a combined company operating an expanded business with a different mix of assets, risks and liabilities. Current Bank First and Centre shareholders may not wish to continue to invest in the combined company, or for other reasons may wish to dispose of some or all of their shares of the combined company.

 ***After the merger is completed, Centre shareholders who receive shares of Bank First common stock in the merger will have different rights that may be less favorable than their current rights as Centre shareholders.***

After the closing of the merger, Centre shareholders who receive shares of Bank First common stock in the merger will have different rights than they currently have as Centre shareholders, which may be less favorable than their current rights as Centre shareholders. For a detailed discussion of the significant differences between the current rights of a shareholder of Centre and the rights of a shareholder of the combined company following the merger, see "Comparison of Shareholders' Rights" beginning on page [118](#tCOSR).

#### Risks Related to Tax

#### The merger may fail to qualify as a "reorganization" within the meaning of Section 368(a) of the Code.
Each of Bank First and Centre intends and expects the merger to qualify as a "reorganization" within the meaning of Section 368(a) of the Code, and the obligation of each of Bank First and Centre to complete the merger is conditioned upon the receipt by each company of a U.S. federal income tax opinion to that effect from their respective legal counsels. These tax opinions represent the legal judgment of counsel rendering the opinion and are not binding on the IRS or the courts. If the merger were to fail to qualify as a reorganization within the meaning of Section 368(a) of the Code, then the merger would be treated as a taxable sale of the assets of Centre to Bank First followed by a taxable liquidation of Centre. Generally, the deemed sale of the assets of Centre would result in gain or loss to Centre equal to the difference between (1) the fair market value of the merger consideration and (2) the adjusted tax basis in such assets held by Centre, and Centre would be subject to corporate income tax on such gain or loss. Generally, the deemed distribution of the merger consideration in the deemed liquidation of Centre would result in taxable gain or loss to the holders of Centre common stock equal to the difference between (1) the fair market value of the merger consideration distributed in respect of their shares of Centre common stock and (2) the tax basis in their shares of such Centre common stock surrendered in exchange therefor. The tax consequences of the merger to any particular shareholder will depend on that shareholder's individual situation. **We strongly urge you to consult your own independent tax advisor to determine the particular tax consequences of the merger to you.**

[**TABLE OF CONTENTS**](#TOC)

#### Risks Related to Bank First's Business
You should read and consider risk factors specific to Bank First's business that will also affect the combined company after the merger. These risks are described in the sections entitled "Risk Factors" Bank First's Annual Report on Form 10-K for the year ended [December 31, 2024](https://www.sec.gov/ix?doc=/Archives/edgar/data/1746109/000155837025001937/bfc-20241231x10k.htm), and in other documents incorporated by reference into this proxy statement/prospectus. Please see the section entitled "Where You Can Find More Information" beginning on page [135](#tWYCF) of this proxy statement/prospectus for the location of information incorporated by reference into this proxy statement/prospectus.

------

[**TABLE OF CONTENTS**](#TOC)

#### CENTRE SPECIAL MEETING
 *This proxy statement/prospectus is being provided to the holders of Centre common stock as part of a solicitation of proxies by the Centre board of directors for use at the Centre special meeting to be held at the time and place specified below and at any properly convened meeting following an adjournment thereof. This proxy statement/prospectus provides the holders of Centre common stock with information they need to know to be able to vote or instruct their vote to be cast at the Centre special meeting.* 

#### General
This section contains information about the special meeting that Centre has called to allow Centre shareholders to vote on the approval of the Centre merger proposal and the Centre adjournment proposal. The Centre board of directors is mailing this proxy statement/prospectus to you, as a Centre shareholder, on or about October 2, 2025. Together with this proxy statement/prospectus, the Centre board of directors is also sending you a notice of the special meeting of Centre shareholders and a form of proxy that the Centre board of directors is soliciting for use at the special meeting and at any adjournments or postponements of the Centre special meeting.

#### Date, Time and Place of Centre Special Meeting
The special meeting of Centre shareholders will be held on November 13, 2025, at 9:00 a.m., Central Time, at 345 E Grand Ave., Beloit, Wisconsin 53511, subject to any adjournment or postponement thereof.

#### Matters to be Considered
At the Centre special meeting, the holders of Centre common stock will be asked to consider and vote upon the Centre merger proposal and, if necessary, the Centre adjournment proposal. Completion of the merger is conditioned on, among other things, approval of the Centre merger proposal by the Centre shareholders. No other business may be conducted at the Centre special meeting. At this time, the Centre board of directors is unaware of any other matters that may be presented for action at the Centre special meeting. If any other matters are properly presented, however, and you have completed, signed and submitted your proxy, the person(s) named as proxy will have the authority to vote your shares in accordance with his or her judgment with respect to such matters.

#### Proposal One: Centre Merger Proposal
Centre is asking its shareholders to approve the Centre merger proposal. Holders of Centre common stock should read this proxy statement/prospectus carefully and in its entirety, including the annexes, for more detailed information concerning the merger agreement and the merger. A copy of the merger agreement is attached to this proxy statement/prospectus as <u>Annex A</u>.

After careful consideration, the Centre board of directors, by a unanimous vote of all directors, approved the merger agreement and declared the merger agreement and the transactions contemplated thereby, including the merger, to be advisable and in the best interest of Centre and its shareholders. See "The Merger Agreement" beginning on page [70](#tTMA) and <u>Annex A</u> of this proxy statement/prospectus for a detailed discussion of the merger, including the terms and conditions of the merger agreement, and "The Merger — Centre's Reasons for the Merger; Recommendation of the Centre Board of Directors" beginning on page [48](#tCRFT) of this proxy statement/prospectus for a more detailed discussion of the Centre board of directors' recommendation.

#### Proposal Two: Centre Adjournment Proposal
If, at the Centre special meeting, the number of shares of Centre common stock present or represented and voting in favor of the Centre merger proposal is insufficient to approve the Centre merger proposal, Centre may move to adjourn the Centre special meeting to enable the Centre board of directors to solicit additional proxies for approval of the Centre merger proposal. In that event, Centre shareholders will be asked to vote upon the Centre adjournment proposal and not the Centre merger proposal.

------

In the Centre adjournment proposal, Centre is asking its shareholders to authorize the holder of any proxy solicited by its board of directors to vote in favor of granting discretionary authority to the Centre board of directors to adjourn the Centre special meeting to another time and place for the purpose of soliciting additional proxies. If Centre's shareholders approve the Centre adjournment proposal, Centre could adjourn the Centre special meeting and any adjourned session of the Centre special meeting and use the additional time to solicit additional proxies, including the solicitation of proxies from Centre shareholders who have previously voted. If a quorum is not present at the meeting, the meeting will not be convened to conduct business and neither the Centre merger proposal nor the Centre adjournment proposal will be considered. In the absence of a quorum, Centre may adjourn the meeting to a later date or time to solicit additional proxies.

#### Recommendation of the Centre Board of Directors
On July 17, 2025, the Centre board of directors unanimously determined that the merger agreement, the merger and the other transactions contemplated by the merger agreement are in the best interests of Centre and its shareholders, and it adopted the merger agreement and approved the merger and the other transactions contemplated by the merger agreement. Accordingly, the Centre board of directors unanimously recommends that Centre shareholders vote "**FOR**" the Centre merger proposal and, if necessary, vote "**FOR**" the Centre adjournment proposal.

#### Record Date and Quorum
September 26, 2025 has been fixed as the record date for the determination of Centre shareholders entitled to notice of, and to vote at, the Centre special meeting and any adjournment or postponement thereof. At the close of business on the record date, there were 1,478,333 shares of Centre common stock outstanding and entitled to vote at the Centre special meeting, held by approximately 233 holders of record.

A quorum is necessary to transact business at the Centre special meeting. The presence, in person or by proxy, of the holders of a majority of the outstanding shares of Centre common stock entitled to vote at the meeting is necessary to constitute a quorum. Shares of Centre common stock represented at the Centre special meeting but not voted, including shares that a shareholder abstains from voting, will be counted for purposes of establishing a quorum. Once a share of Centre common stock is represented at the Centre special meeting, it will be counted for the purpose of determining a quorum not only at the Centre special meeting but also at any adjournment or postponement of the Centre special meeting. In the event that a quorum is not present at the Centre special meeting, it is expected that the Centre special meeting will be adjourned or postponed.

#### Required Vote; Treatment of Abstentions; Broker Non-Votes and Failure to Vote
*The Centre Merger Proposal*. The affirmative vote of the holders of at least a majority of the outstanding shares of Centre common stock is required to approve the Centre merger proposal. If you fail to vote in person or by proxy or fail to instruct your bank, broker or other nominee to vote, or if you mark "ABSTAIN" on your proxy card, with respect to the Centre merger proposal, it will have the same effect as a vote "AGAINST" the proposal.

*The Centre Adjournment Proposal*. The Centre adjournment proposal will be approved if the votes cast favoring the action exceed the votes cast opposing the action. If you fail to vote in person or by proxy or fail to instruct your bank, broker or other nominee to vote, or if you mark "ABSTAIN" on your proxy card, with respect to the Centre adjournment proposal, you will not be deemed to have cast a vote with respect to such proposal, and it will have no effect on such proposal.

The Centre board of directors encourages you to complete, date and sign the enclosed proxy card that is applicable to your shares of Centre common stock and return it promptly in the enclosed postage-paid envelope so that your voice is heard on these matters. If you hold your shares in "street name" through a broker, bank or other nominee, you should direct the vote of your shares in accordance with the voting instruction form received from your broker, bank or other nominee.

#### Voting and Revocation of Proxies
Proxies, in the forms enclosed, which are properly executed and returned and not subsequently revoked, will be voted in accordance with the instructions indicated on the proxies. Any properly executed proxy on which voting instructions are not specified will be voted "**FOR**" the Centre merger proposal and "**FOR**" the Centre adjournment proposal, if applicable.

If you are a shareholder of record of Centre common stock as of September 26, 2025, the Centre record date, you may vote by proxy before the Centre special meeting in any of the following ways:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • **You may vote by mail.** You may vote by mail by completing, signing, dating and returning the enclosed proxy card in the accompanying prepaid reply envelope.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • **You may vote in person at the meeting.** You may vote by attending the Centre special meeting and casting your vote in person at the meeting.

If you intend to submit your proxy by mail, your completed proxy card must be received prior to the Centre special meeting.

If you are the record holder of Centre common stock, you may revoke your proxy at any time before it is voted at the Centre special meeting by:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • delivering written notice of revocation to the pursuant to the instructions below; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • attending the Centre special meeting and notifying the election officials that you wish to revoke your proxy and vote in person.

All written notices of revocation and other communications with respect to revocation or proxies should be sent to: Centre 1 Bancorp, Inc., 345 East Grand Avenue, Beloit, Wisconsin 53511, Attention: Christy M. Farmer. Attendance at the Centre special meeting will not, by itself, revoke your proxy. If you hold your shares in street name with a bank, broker or other nominee, you must contact such bank, broker or other nominee for instructions as to how to revoke your proxy.

#### Shares Held in "Street Name"; Broker Non-Votes
Banks, brokers or other nominees who hold shares of Centre common stock in "street name" for a beneficial owner of those shares typically have the authority to vote in their discretion on "routine" proposals when they have not received instructions from beneficial owners. However, banks, brokers and other nominees are not allowed to exercise their voting discretion with respect to the approval of matters determined to be "non-routine," without specific instructions from the beneficial owner. Broker non-votes are shares held by a broker, bank or other nominee that are represented at the Centre special meeting, but with respect to which the broker or nominee is not instructed by the beneficial owner of such shares to vote on the particular proposal and the broker does not have discretionary voting power on such proposal. As a result, we do not expect any broker non-votes at the Centre special meeting.

If your bank, broker or other nominee holds your shares of Centre common stock in "street name," your bank, broker or other nominee will vote your shares of Centre common stock only if you provide instructions on how to vote by filling out the voter instruction form sent to you by your bank, broker or other nominee with this proxy statement/prospectus.

#### Shares Subject to Voting Agreement; Shares Held by Directors and Executive Officers
All directors and executive officers of Centre, solely in their capacity as shareholders of Centre, have entered into voting agreements with Bank First pursuant to which they have agreed to vote their shares of Centre common stock in favor of the approval of the merger agreement and the merger and against the approval or adoption of any proposal made in opposition to the merger. As of the Centre record date, 291,382 shares of Centre common stock, or approximately 19.71% of the outstanding shares of Centre common stock entitled to vote at the Centre special meeting, are bound by the voting agreements.

#### THE MERGER
 *The following discussion contains certain information about the merger. The discussion is subject, and qualified in its entirety by reference, to the merger agreement attached as <u>Annex A</u> to this proxy statement/prospectus and incorporated herein by reference. We urge you to read carefully this entire proxy statement/prospectus, including the merger agreement attached as <u>Annex A</u>, for a more complete understanding of the merger.* 

#### General
Each of Bank First's and Centre's respective boards of directors has unanimously approved the merger agreement and the transactions contemplated by the merger agreement. The merger agreement provides for the acquisition of Centre by Bank First pursuant to the merger of Centre with and into Bank First, with Bank First as the surviving company, which we refer to as the merger. Immediately after the merger, First National Bank, a national banking association and wholly-owned subsidiary of Centre, will be merged with and into Bank First, N.A., a national banking association and wholly-owned bank subsidiary of Bank First, with Bank First, N.A. as the surviving bank, which we refer to as the bank merger.

#### Purchase Price and Purchase Price Adjustments
At the effective time of the merger, each share of Centre common stock issued and outstanding immediately prior to the effective time of the merger will be converted into the right to receive 0.9200 of a share of Bank First common stock (the "merger consideration"). Each outstanding share of Bank First's common stock will remain outstanding and unaffected by the merger. Before deciding how to vote, you should obtain more recent prices of Bank First common stock, which trades on the Nasdaq Capital Market under the symbol "BFC."

The merger consideration is also subject to a downward adjustment based on Centre's tangible book value at closing. If Centre's tangible book value (as calculated per the merger agreement) is less than $83,587,000 (which we refer to as the "minimum Centre tangible book value") at the time of the closing of the merger, then the merger consideration will be adjusted downward by an amount that is reflective of the overall shortfall between the minimum Centre tangible book value and Centre's tangible book value at closing.

Bank First will not issue any fractional shares of Bank First common stock in the merger. Instead, a Centre shareholder who otherwise would have received a fraction of a share of Bank First common stock will receive an amount in cash (without interest and rounded to the nearest cent) determined by multiplying (1) the per share volume weighted average price of Bank First common stock as reported on the Nasdaq Capital Market during the ten consecutive trading days immediately prior to the fifth trading day prior to closing by (2) the fraction of a share (rounded to the nearest one hundredth of a share) of Bank First common stock to which such shareholder would otherwise be entitled to receive.

Centre may terminate the merger agreement if (i) the average closing price of Bank First common stock over the ten consecutive trading days immediately preceding the date that all regulatory approvals for the merger has been received is less than $110.06, and (ii) the decline in the price of Bank First common stock (as measured by the average closing price divided by $125.78) is more than 12.5% greater than the decline in the Nasdaq Bank Index (as measured by dividing the average closing price of the Nasdaq Bank Index over the ten trading days immediately preceding the date that all regulatory approvals for the merger has been received by $4,535.06); *provided, however*, that Bank First has the option, but not the obligation, to adjust the exchange ratio to prevent the termination of merger agreement.

Centre's shareholders are being asked to approve the merger agreement and the merger. See "The Merger Agreement" for additional and more detailed information regarding the legal documents that govern the merger, including information about the conditions to the completion of the merger and the provisions for terminating or amending the merger agreement.

#### Background of the Merger
As part of its ongoing consideration and evaluation of Centre's long-term business strategy, the Centre board of directors has engaged in periodic reviews during which the board discussed Centre's strategic direction, performance and prospects in the context of trends and developments in the markets that Centre serves, the banking industry and the regulatory environment. As part of these strategic reviews, the Centre board of directors consulted with its financial and legal advisors. Among other things, these discussions have focused on the highly competitive landscape, increased regulatory and technology requirements and recent bank acquisition transactions in Wisconsin and Northern Illinois, as well as possible strategic alternatives available to Centre.

Centre and Bank First began a business relationship in 2020 through loan participations and mutual customers. This relationship grew over time and provided an opportunity for the parties to learn about each other's culture, approach to customers and general strategies. During this time, Steven M. Eldred, Centre's Chief Executive Officer and Chairman, and Michael B. Molepske, Bank First's Chief Executive Officer and Chairman, periodically discussed trends in the financial services industry and matters of mutual interest to their respective institutions. These discussions occurred telephonically and in social and community settings.

At an industry conference in January 2025, a representative of Hovde arranged a meeting with Donald A. O'Day, Centre's President, and Mr. Molepske, to discuss banking industry trends, Bank First's general growth strategies and outlook regarding strategic acquisitions, and the general characteristics each of Bank First and Centre would look for in a possible strategic partner.

On April 22, 2025, at the invitation of Mr. Molepske, Mr. Eldred and Mr. O'Day met with Mr. Molepske and other members of Bank First's senior management team at Bank First's headquarters in Manitowoc, Wisconsin. During the meeting, they visited several of Bank First's branch locations and discussed Bank First's level of interest in Centre's markets, the state of the banking industry and their respective organizations and strategies. This discussion supported the parties' beliefs that each shared many of the same views about those subjects. Mr. Molepske expressed Bank First's interest in exploring a strategic transaction if Centre had interest.

At its meeting on May 15, 2025, the Centre board of directors discussed Centre's strategic alternatives, including a possible partnership with Bank First. At the conclusion of the meeting, the Centre board of directors approved the formation of a capital committee to oversee Centre's management and financial and legal advisors throughout the strategic process and authorized the capital committee to continue evaluating and negotiating a potential proposal with Bank First. The capital committee consisted of Mr. Eldred, Mr. O'Day, along with directors Henry W. Knueppel and James L. Packard. The Centre board of directors also authorized the engagement of Hovde to serve as Centre's financial advisor to assist it in its evaluation of strategic alternatives, including with respect to any acquisition proposals received from Bank First. On May 22, 2025, Centre and Bank First entered into a joint confidentiality agreement.

On May 23, 2025, Bank First delivered a non-binding indication of interest with respect to a business combination in which Bank First would acquire Centre for aggregate consideration of approximately $141 million to $144 million, consisting of either (i) merger consideration of $98.00 per share of Centre common stock in a 100% stock transaction or (ii) merger consideration of $96.00 per share of Centre common stock in a combination of cash and Bank First common stock, subject to no more than 10% Centre common shares receiving the cash consideration. The indication of interest contained other standard and customary preliminary terms, including a request that Centre would grant Bank First a 60-day exclusivity period during which Centre would not be permitted to discuss a possible transaction with another financial institution. Centre's capital committee reviewed the indication of interest with its financial and legal advisors and directed representatives of Hovde to contact Bank First to determine whether terms of the indication of interest could be improved.

------

[**TABLE OF CONTENTS**](#TOC)

On June 7, 2025, Bank First delivered a revised non-binding indication of interest with a proposed aggregate consideration of $155.5 million, based on Bank First's closing stock price on June 6, 2025 of $114.85 per share, offering Centre shareholders 0.9200 of a share of Bank First common stock per share of Centre common stock in a 100% stock transaction. After further discussions between the parties and their financial advisors, on June 12, 2025, Bank First delivered a further revised non-binding indication of interest reducing the double-trigger termination threshold from 20% to 12.5%.

On June 13, 2025, the Centre board of directors met to discuss Bank First's most recent non-binding indication of interest. During the meeting, the capital committee updated the board on the ongoing matters with Bank First and the board held a detailed and lengthy discussion regarding Bank First's revised non-binding indication of interest. Representatives from Barack Ferrazzano Kirschbaum and Nagelberg LLP, legal counsel for Centre (which we refer to as "Barack Ferrazzano") and Hovde participated in the meeting and led a discussion covering various legal and financial considerations regarding the indication of interest. In addition, representatives from Barack Ferrazzano reviewed with the directors the Centre board of directors' fiduciary duties in connection with their consideration of Centre's strategic options, including a transaction with Bank First. The Centre board of directors authorized management to execute the indication of interest with Bank First and to proceed with negotiating the terms of a definitive merger agreement. The parties then began a fulsome due diligence review of each other.

Barack Ferrazzano received an initial draft of the merger agreement from Alston & Bird LLP, legal counsel for Bank First (which we refer to as "Alston & Bird"), on July 1, 2025. That agreement, along with the ancillary bank merger agreement, director and officer voting agreements and non-competition agreements, were negotiated between the parties through July 17, 2025, during which period of time each party also prepared comprehensive disclosure schedules to be delivered concurrently with the merger agreement.

Bank First and its advisors conducted a comprehensive due diligence process regarding Centre through review of certain requested information and documents provided by Centre through an online data room, including numerous supplemental due diligence requests. On July 14, 2025, Alston & Bird conducted a regulatory due diligence conference call with representatives from Centre and Barack Ferrazzano to discuss Centre's regulatory standing with its federal and state regulators.

Centre and its advisors conducted reverse due diligence regarding Bank First through review of Bank First's publicly filed information and other documents and information provided by Bank First through an online data room. Centre engaged in several reverse diligence discussions with representatives from Bank First, covering topics such as documents previously provided to Centre by Bank First, the strategic plan and future growth prospects for Bank First, integration of Centre into Bank First, financial performance, strategic plans specific to Centre's markets, shareholder liquidity, existing lines of business and potential new lines of business.

On July 14, 2025, Centre's board of directors met with members of Centre's executive management team and representatives of Barack Ferrazzano and Hovde. At this meeting, Centre's senior management updated the board on the status of the negotiations of the definitive merger agreement and the reverse due diligence review of Bank First. Representatives of Barack Ferrazzano provided a review of the key terms of the definitive transaction documents, including the merger agreement, directing the attention of the Centre board of directors to an outline summarizing the terms of the merger agreement, the voting agreements, and the confidentiality, non-solicitation and non-competition agreements that had been previously provided to each member of the board. Representatives of Barack Ferrazzano also discussed the legal reverse due diligence review memorandum provided to the board. Representatives of Hovde previewed with the board Hovde's fairness opinion analysis and led a discussion of the mechanics of the exchange ratio.

On July 15, 2025, Bank First's board of directors met at a special meeting to review and discussed the proposed merger and the merger agreement. Management of Bank First reviewed the final terms of the proposed merger agreement and related transaction documents with the Bank First board. Also at this meeting, Piper Sandler & Co. reviewed with the Bank First board its financial analysis of the merger consideration delivered to the Bank First board to the effect that, as of that date and based on and subject to various assumptions and limitations described in its opinion, the "aggregate consideration" to be issued and paid in the merger pursuant to the merger agreement, is fair, from a financial point of view, to Bank First and its shareholders.

[**TABLE OF CONTENTS**](#TOC)

After taking into consideration the matters discussed during this meeting and prior meetings of the Bank First board, including the factors described under the section of this proxy statement/prospectus entitled "The Merger — Bank First's Reasons for the Merger," the Bank First board of directors unanimously approved the merger agreement and related actions.

On July 17, 2025, Centre's board of directors held a meeting to consider the terms of the proposed merger with Bank First and the then-current definitive transaction documents, including the substantially final draft of the merger agreement. As an initial matter, representatives of Barack Ferrazzano reviewed with the directors their fiduciary duties in connection with their review and consideration of the transaction and the terms of the proposed merger with Bank First. Centre's board of directors was reminded that this information regarding the board of directors' fiduciary duties had been provided and discussed at prior board meetings.

After further discussion among members of Centre's board of directors, representatives of Barack Ferrazzano led a comprehensive review of the definitive transaction documents, including the merger agreement, the voting agreements, and the confidentiality, non-solicitation and non-competition agreements.

Following this discussion, representatives of Hovde reviewed the financial aspects of the proposed merger and discussed in detail their financial analyses as of the date of the meeting, including those described in the section entitled "The Merger — Opinion of Centre's Financial Advisor" beginning on page [51](#tOOCF). At this meeting, Hovde delivered an oral opinion to the Centre board of directors (which was subsequently confirmed in a written opinion, dated as of July 17, 2025) to the effect that as of July 17, 2025, subject to the matters, assumptions and limitations set forth in the opinion and pursuant to the terms of the merger agreement, the merger consideration is fair, from a financial point of view, to the holders of shares of Centre common stock, as in more detail in the section entitled "The Merger — Opinion of Centre's Financial Advisor" beginning on page [51](#tOOCF).

During the meeting, Centre's management and legal advisors reported on, and the Centre board of directors discussed in detail, the reverse due diligence process undertaken by Centre and its advisors with respect to Bank First. Centre's management reported favorably regarding the complementary culture and business objectives of Bank First and Centre, noting that the respective customer focus, geographic coverage and historical relationships with borrowers and customers of Bank First and Centre evidenced that the two companies shared a similar business orientation.

Following extensive discussion and after considering the foregoing and the proposed terms of the transaction documents, and taking into account the strategic rationale, financial terms, consideration, integration risk and business rationale of consummating a merger with Bank First, including the factors described in the section entitled "The Merger — Centre's Reasons for the Merger; Recommendation of the Centre Board of Directors," the Centre board of directors, having determined that the terms of Bank First's proposal, the related merger agreement and the transactions contemplated thereby, including the merger, were fair to and in the best interests of Centre and its shareholders, unanimously approved and declared advisable the merger agreement and the transactions contemplated thereby, including the merger and the exchange ratio, at the meeting. The board directed that the merger agreement be submitted to Centre shareholders for approval and recommended that Centre shareholders vote in favor of the approval of the merger agreement and the transactions contemplated thereby.

The merger agreement and related documents were executed by the parties on July 17, 2025. The transaction was announced the morning of July 18, 2025 in a joint press release issued by Bank First and Centre.

#### Bank First's Reasons for the Merger
In reaching its decision to approve and adopt the merger agreement, the merger and the other transactions contemplated by the merger agreement, including the issuance of Bank First common stock as the merger consideration, the Bank First board of directors considered a number of factors, including the following material factors:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • each of Bank First's and Centre's business, operations, financial condition, asset quality, earnings, and prospects;

------

[**TABLE OF CONTENTS**](#TOC)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the strategic fit of the businesses of the two companies, including their complementary markets, business lines and loan and deposit profiles;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Centre's established presence in Wisconsin, which will add increased scale and density for Bank First in Wisconsin;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Centre's presence in northern Illinois, which will expand Bank First's geographic footprint beyond Wisconsin for the first time;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the opportunity to add seasoned bankers in Centre's markets and strengthen Bank First's presence and leadership throughout Wisconsin and into Illinois;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the potential to broaden the scale of Bank First's organization and the expanded possibilities, including organic growth and future acquisitions, that would be available to the combined company, given its larger size, asset base, capital, and geographic footprint;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the merger consideration and the other amounts to be paid or incurred in connection with the merger;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the impact of the issuance of Bank First common stock in the merger on the existing shareholders of Bank First, including the expected earnback period for the resulting dilution;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the anticipated pro forma impact of the transaction on the combined company, including the expected impact on financial metrics including earnings and tangible book value and regulatory capital levels, as well as the potential efficiencies of scale resulting from the increased size of Bank First following the merger;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the anticipated benefits resulting from the expected larger market capitalization of Bank First resulting from the merger;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the expectation of annual cost savings resulting from the merger, enhancing efficiencies;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • its understanding of the current and prospective environment in which Bank First and Centre operate, including national, state and local economic conditions, the competitive environment for financial institutions generally, and the likely effect of these factors on Bank First both with and without the proposed transaction;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • its review and discussions with Bank First's management concerning the due diligence investigation of Centre, including its review of Centre's financial condition, results of operation, asset quality, market areas, growth potential (projected potential accretion to earnings per share and the projected payback period of the estimated decrease in tangible book value) and quality of senior management;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the perceived compatibility of the corporate cultures of the two companies, which management believes should facilitate integration and implementation of the transaction;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the structure of the transaction as a combination in which the combined company would operate under the Bank First brand and Bank First's board of directors and management would have substantial participation in the combined company;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the regulatory and other approvals required in connection with the merger and the expectation that such regulatory approvals will be received in a timely manner and without the imposition of unacceptable conditions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Bank First's successful track record of creating shareholder value through past acquisitions, including Bank First's proven experience in successfully integrating acquired businesses and retaining key personnel, and Bank First's management's belief that it will be able to successfully integrate Centre with Bank First; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the financial and other terms of the merger agreement, including the merger consideration, expected tax treatment, the deal protection and termination fee provisions, and restrictions on the conduct of Centre's business between the date of the merger agreement and the date of completion of the merger.

------

[**TABLE OF CONTENTS**](#TOC)

Bank First's board of directors also considered potential risks relating to the merger including the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Bank First management's attention and Bank First resources may be diverted from the operation of Bank First's business and towards the completion of the merger;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Bank First may not realize all of the anticipated benefits of the merger, including cost savings, maintenance of existing customer and employee relationships, and minimal disruption in the integration of Centre's operations with Bank First;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the nature and amount of payments and other benefits to be received by Centre management in connection with the merger pursuant to existing Centre plans and compensation arrangements and the merger agreement;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the impact of the dilution resulting from the stock issuance on Bank First's current shareholders, and the ability of Bank First to realize the benefits of the merger in a reasonable time frame to offset the effects of such dilution;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the possibility of encountering difficulties in completing the merger;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the possibility of encountering difficulties in successfully integrating Centre's business, operations, and workforce with those of Bank First;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the substantial costs that Bank First will incur in connection with the merger even if it is not consummated;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the regulatory and other approvals required in connection with the merger and the risk that such regulatory approvals will not be received in a timely manner or may impose unacceptable conditions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the possibility of litigation in connection with the merger;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the possibility of negative investor perception of the merger, including as a result of the perceived heightened risk associated with a merger of this size; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • other risks associated with business combinations in the financial services industry, including those set forth in this proxy statement/prospectus under the heading "Risk Factors" beginning on page [30](#tRIFA).

The foregoing discussion of the factors considered by the Bank First board of directors is not intended to be exhaustive, but, rather, includes the material factors primarily considered by the Bank First board of directors. In reaching its decision to approve the merger agreement and the transactions contemplated thereby, including the merger and the issuance of shares of Bank First common stock as merger consideration, the Bank First board of directors did not quantify or assign any relative weights to the factors considered, and individual directors may have given different weights to different factors. The Bank First board of directors considered all of these factors as a whole and overall considered the factors to be favorable to, and to support, its determination. It should be noted that this explanation of the Bank First board of directors' reasoning and all other information presented in this section is forward-looking in nature and, therefore, should be read in light of the factors discussed under the heading "Special Cautionary Note Regarding Forward-Looking Statements" beginning on page [27](#tSCNR).

#### Centre's Reasons for the Merger; Recommendation of the Centre Board of Directors
After careful consideration, at its meeting on July 17, 2025, the Centre board of directors determined that the merger is in the best interests of Centre and its shareholders and that the price to be received in the merger is fair to the Centre shareholders. Accordingly, the Centre board of directors unanimously approved the merger agreement and recommended that the Centre shareholders vote "**FOR**" the Centre merger proposal.

In reaching its decision to approve the merger agreement and recommend the merger to its shareholders, the Centre board of directors evaluated the merger and the merger agreement, in consultation with Centre's management, as well as its legal and financial advisors, and considered a number of positive factors, including the following material factors, which are not presented in order of priority:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the Centre board of directors' familiarity with and review of Bank First's business, financial condition, results of operations and prospects, including, but not limited to, its business plan and its potential for growth, development, productivity and profitability;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the likelihood that acquisition opportunities for Centre as a buyer are limited due to the lower comparative valuation of Centre shares and the limited number of attractive acquisition targets;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the potential risks associated with 100% of the merger consideration being paid through the issuance of shares of Bank First common stock and any decrease in the market price of Bank First common stock will result in a reduction in the aggregate merger consideration received by Centre shareholders;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the potential risk of diverting management attention and resources from the day-to-day operation of Centre's business and towards the completion of the merger;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the merger agreement provisions generally requiring Centre to conduct its business in the ordinary course and the other restrictions on the conduct of Centre's business prior to consummation of the merger, which may delay or prevent Centre from undertaking business opportunities that may arise pending consummation of the merger;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • expected benefits and synergies sought in the merger, including cost savings and Bank First's ability to successfully market its products and services to Centre's customers, may not be realized within the expected time period, or at all;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • that Centre shareholders will not necessarily know or be able to calculate the actual value of the merger consideration which they would receive upon completion of the merger.

The foregoing discussion of the information and factors considered by the Centre board of directors is not intended to be exhaustive, but to include a description of material factors considered by the Centre board of directors. In reaching its decision to approve the merger agreement and the transactions contemplated therein, including the merger, the Centre board of directors did not quantify or assign any relative weights to the factors considered, and individual directors may have given different weights to different factors. The Centre board of directors considered all these factors as a whole, including discussions with, and questioning of, Centre's management and Centre's independent financial and legal advisors and overall considered the factors to be favorable to, and to support, its determination.

**The Centre board of directors unanimously recommends that Centre shareholders vote "FOR" the Centre merger proposal and "FOR" the Centre adjournment proposal.** Centre shareholders should be aware that Centre's directors and executive officers have interests in the merger that are different from, or in addition to, those of other Centre shareholders. The Centre board of directors was aware of and considered these interests, among other matters, in evaluating and negotiating the merger agreement, and in recommending that the Centre merger proposal be approved by the Centre shareholders. See "The Merger — Interests of Centre's Directors and Executive Officers in the Merger" beginning on page [61](#tIOCD) and "The Merger Agreement — Indemnification and Directors' and Officers' Insurance" beginning on page [82](#tIADA).

This summary of the reasoning of the Centre board of directors and other information presented in this section are forward-looking in nature and, therefore, should be read in light of the factors discussed under the heading "Special Cautionary Note Regarding Forward-Looking Statements."

#### Opinion of Centre's Financial Advisor
The fairness opinion and a summary of the underlying financial analyses of Centre's financial advisor, Hovde, are described below. Capitalized terms not otherwise defined in the following summary and description shall have the meanings as set forth in the draft of the merger agreement, dated July 15, 2025, which was provided to Hovde by Centre, and all references to Articles and Sections cited herein shall refer to Articles and Sections in the merger agreement. Hovde has been informed by Centre that the terms of the final merger agreement, dated July 17, 2025, and executed by Centre and Bank First do not differ in any material respect from the terms set forth in the draft merger agreement utilized by Hovde for purposes of its analysis and opinion. The summary and description set forth below contain projections, estimates and other forward-looking statements about the future earnings or other measures of the future performance of Centre and Bank First. The projections were based on numerous variables and assumptions, which are inherently uncertain, including factors related to general economic and competitive conditions. Accordingly, actual results could vary significantly from those set forth in the projections. You should not rely on any of these statements as having been made or adopted by Centre or Bank First. **You should review the copy of the Hovde opinion, which is attached as <u>Annex C</u> to this document*.*** 

Hovde acted as Centre's financial advisor in connection with the merger. As used in this section, pursuant to the terms of the merger agreement, "merger" refers to the acquisition of Centre by Bank First as a result of the merger of Centre with and into Bank First, following which First National Bank will merge with and into Bank First, N.A. As part of its investment banking business, Hovde is continually engaged in the valuation of businesses and their securities in connection with, among other things, mergers and acquisitions. Hovde has experience in, and knowledge of, banks, thrifts and their respective holding companies, and is familiar with Centre and Bank First and their respective operations. The Centre board of directors selected Hovde to act as its financial advisor in connection with the merger based on the firm's reputation and expertise in transactions such as the merger as set forth in the merger agreement. Hovde reviewed the financial aspects of the merger with the Centre board of directors and, on July 17, 2025, delivered a written opinion to the Centre board of directors that, subject to the matters, assumptions and limitations set forth in the opinion and pursuant to the terms of the merger agreement, the merger consideration is fair, from a financial point of view, to the holders of shares of Centre common stock. In requesting Hovde's advice and opinion, no limitations were imposed by Centre upon Hovde with respect to the investigations made or procedures followed by Hovde in rendering its opinion.

The full text of the written opinion of Hovde is attached as <u>Annex C</u> to this document. You are urged to read the opinion in its entirety for a description of the procedures followed, assumptions made, matters considered and qualifications and limitations on the review undertaken by Hovde. The summary of Hovde's opinion included in this proxy statement/prospectus is qualified in its entirety by reference to the full text of such opinion.

Hovde's opinion was directed to the Centre board of directors and addresses only the fairness of the merger consideration to the shareholders of Centre. Hovde did not opine on any individual stock, cash, or other components of consideration payable in connection with the merger. Hovde's opinion does not constitute a recommendation to Centre as to whether or not it should enter into the merger agreement or to any Centre shareholders as to how such shareholders should vote at any meetings of shareholders called to consider and vote upon the merger. Hovde's opinion does not address the underlying business decision to proceed with the merger or the fairness of the amount or nature of the compensation, if any, to be received by any of the officers, directors or employees of Centre relative to the amount of consideration to be received by Centre shareholders with respect to the merger. Hovde's opinion should not be construed as implying that the merger consideration to be received by Centre shareholders from the merger is necessarily the highest or best price that could be obtained by Centre in a sale transaction or combination transaction with a third party. Other than as specifically set forth in its opinion, Hovde is not expressing any opinion with respect to the terms and provisions of the merger agreement or the enforceability of any such terms or provisions. Hovde's opinion is not a solvency opinion and does not in any way address the solvency or financial condition of Centre or Bank First. Hovde's opinion was approved by Hovde's fairness opinion committee.

------

[**TABLE OF CONTENTS**](#TOC)

Centre engaged Hovde on June 12, 2025 to serve as the exclusive financial advisor to Centre in connection with a potential transaction and to issue an opinion to the Centre board of directors in connection with a potential transaction. Pursuant to Centre's engagement agreement with Hovde, Hovde received a fee of $250,000 upon the delivery of the fairness opinion to Centre, which will be fully credited one time against any completion fee due to Hovde upon the consummation of the merger. Based upon Hovde's assumption for purposes of its analysis and opinion that the total merger value is $167,958,493 (as described herein below), the net completion fee due to Hovde upon the consummation of the merger will be approximately $2,269,377, after providing full credit to the total completion fee of approximately $2,519,377 for the fairness opinion fee of $250,000. In addition to Hovde's fairness opinion and completion fees, and regardless of whether the merger is consummated, Centre has agreed to reimburse Hovde for certain of its reasonable out-of-pocket expenses and has also agreed to indemnify Hovde and its affiliates for certain liabilities that may arise out of Hovde's engagement.

Other than in connection with this present engagement, during the two years preceding the date of the opinion, Hovde has not provided investment banking or financial advisory services to either Centre or Bank First for which it received a fee. Hovde or its affiliates may presently or in the future seek or receive compensation from Bank First in connection with future transactions, or in connection with potential advisory services and corporate transactions, although, to Hovde's knowledge, none are expected at this time. In the ordinary course of its business as a broker/dealer, Hovde may from time-to-time purchase securities from, and sell securities to, Centre, Bank First or their affiliates. Except for the foregoing, during the two years preceding the date of the opinion, there have not been, and there currently are no mutual understandings contemplating in the future any material relationships between Hovde and Bank First.

For purposes of Hovde's analysis and opinion and with the knowledge and consent of Centre, Hovde assumed: (i) there would be no adjustment to or reduction of the merger consideration; (ii) there would be no adjustment to the exchange ratio of 0.9200 pursuant to the provisions of Section 7.01(h) of the merger agreement; (iii) the closing price of Bank First common stock on the Nasdaq Capital Market as of July 16, 2025 was $121.22 per share; (iv) there are 1,501,016 shares of Centre common stock outstanding (including 24,683 shares issued due to the vesting of Centre performance based restricted stock units); and (v) thereby the total value of the merger consideration is $167,396,907. Additionally, Hovde assumed: (i) there are 15,000 Centre stock options outstanding with a weighted average exercise price of $74.08 per share of Centre common stock; (ii) based on the exchange ratio of 0.9200 the per share cash equivalent consideration is $111.52; and (iii) thereby the total value of the Centre stock option payments is $561,586. Accordingly, Hovde assumed that the total value of the merger is $167,958,493, which is the sum of the merger consideration of $167,396,907 and the total value of the Centre stock options payments of $561,586. Additionally, Hovde assumed that: (i) all of the closing conditions set forth in Article VI of the merger agreement are satisfied; (ii) the merger is not terminated pursuant to any of the provisions set forth in Article VII of the merger agreement; and (iv) the merger will proceed and be consummated in accordance with the terms of the merger agreement.

During the course of Hovde's engagement and for the purposes of its opinion Hovde:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (i)

reviewed a draft of the merger agreement, dated July 15, 2025, provided to Hovde by Centre;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (ii)

reviewed audited financial statements for Centre and First National Bank for the twelve month periods ended December 31, 2022, December 31, 2023 and December 31, 2024 and the unaudited statements for the three month period ended March 31, 2025;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (iii)

reviewed audited financial statements for Bank First and Bank First, N.A. for the twelve month periods ended December 31, 2022, December 31, 2023 and December 31, 2024 and the unaudited statements for the three month period ended March 31, 2025;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (iv)

reviewed certain historical publicly available business and financial information concerning Centre and First National Bank;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (v)

reviewed certain internal financial statements and other financial and operating data concerning Centre and First National Bank;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (vi)

reviewed financial projections prepared in consultation with and approved by certain members of the senior management of Centre and First National Bank;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (vii)

discussed with certain members of senior management of Centre and First National Bank the business, financial condition, results of operations and future prospects of Centre and First National Bank, the history and past and current operations of Centre and First National Bank, and Centre's assessment of the rationale for the merger;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (viii)

assessed current general economic, market and financial conditions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (ix)

reviewed the terms of recent merger, acquisition and control investment transactions, to the extent publicly available, involving financial institutions and financial institution holding companies that Hovde considered relevant;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (x)

took into consideration Hovde's experience in other similar transactions and securities valuations as well as its knowledge of the banking and financial services industry; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (xi)

performed such other analyses and considered such other factors as Hovde deemed appropriate.

In performing its review, Hovde assumed, without investigation, that there have been, and from the date of its opinion through the closing there will be, no material changes in the financial condition and results of operations of Centre or Bank First since the date of the latest financial information described above. Hovde further assumed, without independent verification, that the representations and financial and other information included in the merger agreement and all other related documents and instruments that are referred to therein or otherwise provided to Hovde by Centre and Bank First are true and complete. Hovde relied upon the management of Centre as to the reasonableness and achievability of the financial forecasts, projections and other forward-looking information provided to Hovde by them and their professionals, and Hovde assumed such forecasts, projections and other forward-looking information were reasonably prepared by Centre and their professionals on a basis reflecting the best currently available information and their professionals' judgments and estimates. Hovde assumed that such forecasts, projections and other forward-looking information would be realized in the amounts and at the times contemplated thereby, and Hovde does not assume any responsibility for the accuracy or reasonableness thereof. Hovde was authorized by Centre to rely upon such forecasts, projections and other information and data, and Hovde expresses no view as to any such forecasts, projections or other forward-looking information or data, or the bases or assumptions on which they were prepared.

In performing its review, Hovde assumed and relied upon the accuracy and completeness of all of the financial and other information that was available to Hovde from public sources, that was provided to Hovde by Centre, Bank First or their respective representatives, or that was otherwise reviewed by Hovde for purposes of rendering its opinion. Hovde further relied on the assurances of the respective managements of Centre and Bank First that they were not aware of any facts or circumstances that would make any of such information inaccurate or misleading. Hovde was not asked to undertake, and did not undertake, an independent verification of any of such information, and Hovde does not assume any responsibility or liability for the accuracy or completeness thereof. Hovde assumed that Centre and Bank First would advise Hovde promptly if any information previously provided to Hovde became inaccurate or was required to be updated during the period of Hovde's review.

Hovde is not expert in the evaluation of loan and lease portfolios for purposes of assessing the adequacy of the allowances for losses with respect thereto. Hovde assumed that such allowances for Centre and Bank First are, in the aggregate, adequate to cover such losses and will be adequate on a pro forma basis for the combined entity. Hovde was not requested to make, and did not make, an independent evaluation, physical inspection or appraisal of the assets, properties, facilities, or liabilities (contingent or otherwise) of Centre or Bank First, the collateral securing any such assets or liabilities, or the collectability of any such assets, and Hovde was not furnished with any such evaluations or appraisals, nor did Hovde review any loan or credit files of Centre or Bank First.

------

[**TABLE OF CONTENTS**](#TOC)

Hovde undertook no independent analysis of any pending or threatened litigation, regulatory action, possible un-asserted claims or other contingent liabilities to which Centre or Bank First was or is a party or may be subject, and Hovde's opinion makes no assumption concerning, and therefore does not consider, the possible assertion of claims, outcomes or damages arising out of any such matters. Hovde also assumed, with Centre's consent, that both Centre and Bank First are not parties to any material pending transaction, including without limitation any financing, recapitalization, acquisition or transaction, divestiture or spin-off.

Hovde relied upon and assumed, with Centre's consent and without independent verification, that the merger will be consummated substantially in accordance with the terms set forth in the merger agreement, without any waiver of material terms or conditions by Centre, Bank First or any other party to the merger agreement and that the final merger agreement would not differ materially from the draft Hovde reviewed. Hovde assumed that the merger will be consummated in compliance with all applicable laws and regulations. Centre advised Hovde that they were not aware of any factors that would impede any necessary regulatory or governmental approval of the merger. Hovde assumed that the necessary regulatory and governmental approvals as granted will not be subject to any conditions that would be unduly burdensome on Centre or Bank First or would have a material adverse effect on the contemplated benefits of the merger.

Hovde's opinion does not consider, include or address: (i) any legal, tax, accounting or regulatory consequences of the merger on Centre or its shareholders; (ii) any advice or opinions provided by any other advisor to the Centre board of directors; (iii) any other strategic alternatives that might be available to Centre; or (iv) whether Bank First has sufficient cash or other sources of funds to enable it to pay the consideration contemplated by the merger.

Hovde's opinion was based solely upon the information available to Hovde and described above, and the economic, market and other circumstances as they existed as of the date of the opinion. Events occurring and information that becomes available after the date of the opinion could materially affect the assumptions and analyses used in preparing the opinion. Hovde has not undertaken to update, revise, reaffirm or withdraw the opinion or to otherwise comment upon events occurring or information that becomes available after the date of the opinion.

In arriving at the opinion, Hovde did not attribute any particular weight to any single analysis or factor considered by it but rather made qualitative judgments as to the significance and relevance of each analysis and factor. Accordingly, Hovde believes that its analyses must be considered as a whole and that selecting portions of its analyses, without considering all analyses, would create an incomplete view of the process underlying the opinion.

The following is a summary of the material analyses prepared by Hovde and delivered to the Centre board of directors on July 17, 2025, in connection with the delivery of its opinion. This summary is not a complete description of all the analyses underlying the opinion or the presentation prepared by Hovde, but it summarizes the material analyses performed and presented in connection with such opinion. The preparation of an opinion is a complex analytical process involving various determinations as to the most appropriate and relevant methods of financial analysis and the application of those methods to the particular circumstances of the contemplated merger. The financial analyses summarized below include information presented in tabular format. The analyses and the summary of the analyses must be considered as a whole and selecting portions of the analyses and factors or focusing on the information presented below in tabular format without considering all analyses and factors or the full narrative description of the financial analyses, including the methodologies and assumptions underlying the analyses, could create a misleading or incomplete view of the process underlying the analyses and opinion of Hovde. The tables alone are not a complete description of the financial analyses performed by Hovde.

*Market Approach — Comparable Merger and Acquisition Transactions*. As part of its analysis, Hovde reviewed publicly available information related to two comparable groups (which we refer to as the "Regional Group" and the "Nationwide Group") of select bank merger and acquisition transactions based on data obtained from S&P Capital IQ as of July 15, 2025. The Regional Group consisted of transactions where targets were headquartered in Iowa, Illinois, Indiana, Kansas, Kentucky, Michigan, Minnesota, Missouri, North Dakota, Nebraska, Ohio, South Dakota and Wisconsin announced since January 1, 2023, in which the targets' total assets were between $1.0 billion and $3.0 billion.

[**TABLE OF CONTENTS**](#TOC)

The Nationwide Group consisted of transactions in the United States announced since January 1, 2024 in which the targets' total assets were between $1.0 billion and $3.0 billion and last-twelve-months return (which we refer to as "LTM") on average equity was greater than 5.00%. In each case for which financial information was available, no transaction that fit the above selection criteria was excluded, unless such transaction was deemed a "Merger of Equals" by S&P Capital IQ. Information for the target institutions was based on balance sheet data as of, and income statement data for, the twelve months preceding the most recent quarter prior to announcement of the transactions as determined by S&P Capital IQ. The resulting two groups consisted of the following precedent transactions (eight transactions for the Regional Group and 16 transactions for the Nationwide Group):

(1) Represents the premium paid for core capital where: (i) core capital is assumed to equal total tangible assets multiplied by 8%; (ii) excess capital equals total tangible book value less core capital; and (iii) price is adjusted to subtract excess capital (assumes dollar-for-dollar payment of excess capital); Price/Adjusted Tangible Book Value is assumed to equal Price/Tangible Book Value for targets with tangible equity/tangible assets less than 8.00%.

(2) Represents the premium (or discount) paid on tangible book value expressed as a percentage of core deposits. Core deposits are defined as total deposits less brokered deposits, foreign deposits and time deposit accounts greater than $100,000.

For each precedent transactions group, Hovde compared the implied ratio of the total merger value to certain financial metrics of the proposed merger as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the multiple of the total merger value to the acquired company's LTM net earnings (which we refer to as the "Price-to-LTM Earnings Multiple");

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the multiple of the total merger value to the acquired company's tangible book value (which we refer to as the "Price-to-Tangible Book Value Multiple");

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the multiple of the total merger value to the acquired company's adjusted tangible book value (which we refer to as the "Price-to-Adjusted Tangible Book Value Multiple"); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the multiple of the difference between the total merger value and the acquired company's tangible book value to the acquired company's core deposits (which we refer to as the "Premium-to-Core Deposits Multiple").

The results of the analysis are set forth in the table below. Transaction multiples for the merger were based upon the assumed total merger value of $167,958,493 and were based on March 31, 2025 financial results for Centre.

Using publicly available information, Hovde compared the financial performance of Centre with that of the median of the targets from the precedent bank merger and acquisition transactions from each of the Regional and Nationwide Groups. The performance highlights are based on March 31, 2025 financial results of Centre.

(1) Core deposits exclude brokered deposits, foreign deposits and time deposit accounts greater than $100,000.

(2) Loan loss reserve (which we refer to as "LLR") as a percentage of nonperforming loans (which we refer to as "NPLs"); Medians exclude excessively high ratios determined as not meaningful by S&P Capital IQ and ratios that were not applicable for targets that had no NPLs.

No company or transaction used as a comparison in the above transaction analyses is identical to Centre, and no transaction was consummated on terms identical to the terms of the merger agreement. Accordingly, an analysis of these results is not strictly mathematical. Rather, it involves complex considerations and judgments concerning differences in financial and operating characteristics of the companies. The resulting values of the precedent transactions Regional Group using the median values for the four-valuation metrics set forth above indicated an implied total valuation ranging between $107.0 million and $140.4 million with a four-factor implied average total valuation of $118.7 million compared to the assumed total merger value of $168.0 million. The resulting values of the precedent transactions Nationwide Group using the median values for the four-valuation metrics set forth above indicated an implied total valuation ranging between $91.5 million and $156.2 million with a four-factor implied average total valuation of $123.8 million compared to the assumed total merger value of $168.0 million.

*Income Approach — Discounted Cash Flow Analysis*. Centre management approved the financial forecasts for Centre over a forward-looking, five-year period which formed the basis for the discounted cash flow analyses. The projected Centre net income amounts used for the analysis were $7.0 million for 2025, $9.0 million for 2026, $10.8 million for 2027, $12.9 million for 2028 and $14.0 million for 2029. The resulting projected Centre tangible common equity amounts used for the analysis were $88.1 million for the year ended 2025, $98.1 million for the year ended 2026, $109.8 million for the year ended 2027, $123.7 million for year ended 2028 and $138.7 million for the year ended 2029. The resulting projected Centre aggregate dividend amounts used for the analysis were $3.8 million for the year ended 2025, $3.8 million for the year ended 2026, $3.8 million for the year ended 2027, $3.8 million for the year ended 2028 and $3.8 million for the year ended 2029.

For purposes of its discounted cash flow analysis, Hovde reviewed publicly available information related to select comparable bank merger and acquisition transactions (which we refer to as the "Terminal Regional Group") that would be for targets of comparable asset size and profitability to Centre at the end of the five-year period of the projections. Hovde utilized the Regional Group as the Terminal Regional Group which consisted of bank merger and acquisition transactions where targets were headquartered in Iowa, Illinois, Indiana, Kansas, Kentucky, Michigan, Minnesota, Missouri, North Dakota, Nebraska, Ohio, South Dakota and Wisconsin announced since January 1, 2023, in which the targets' total assets were between $1.0 billion and $3.0 billion. In each case for which financial information was available, no transaction that fit the above selection criteria was excluded, unless such transaction was deemed a "Merger of Equals" by S&P Capital IQ. Information for the target institutions was based on balance sheet data as of, and income statement data for, the twelve months preceding the most recent quarter prior to announcement of the transactions as determined by S&P Capital IQ. The resulting group consisted of eight transactions:

(1) Represents the premium paid for core capital where: (i) core capital is assumed to equal total tangible assets multiplied by 8%; (ii) excess capital equals total tangible book value less core capital; and (iii) price is adjusted to subtract excess capital (assumes dollar-for-dollar payment of excess capital); Price/Adjusted Tangible Book Value is assumed to equal Price/Tangible Book Value for targets with tangible equity/ tangible assets less than 8.00%.

(2) Represents the premium or paid on tangible book value, expressed as a percentage of core deposits. Core deposits are defined as total deposits less brokered deposits, foreign deposits and time deposit accounts greater than $100,000.

To determine present values of Centre based on these projections, Hovde utilized two discounted cash flow models, each of which capitalized terminal values using different multiples: (i) Terminal Price/Earnings Multiple (which we refer to as the "DCF Terminal P/E Multiple"); and (ii) Terminal Price/Tangible Book Value Multiple (which we refer to as the "DCF Terminal P/TBV Multiple").

In the DCF Terminal P/E Multiple analysis, an estimated value of Centre was calculated based on the present value of Centre's forward-looking net income and dividend projections over the five-year projection period of the financial forecasts approved by Centre management. The projected net income amount for the year ended 2029 was $14.0 million and served as the basis of the terminal earnings value in the DCF. Hovde calculated a terminal value at the end of 2029 by applying a five-point range of price-to-earnings multiples of 15.8x to 17.8x, which is based around the median price-to-earnings multiple derived from transactions in the Terminal Regional Group of 16.8x. The present value of Centre's projected terminal value was calculated assuming a range of discount rates between 13.20% and 15.20%, with a midpoint of 14.20%, discounted over the 4.46-year period from the date of the opinion to the end of the five-year projection period. This range of discount rates was chosen to reflect different assumptions regarding the required rates of return of holders or prospective holders of Centre common stock. The range of discount rates utilized the buildup method to determine such required rates of return and was based upon the risk-free interest rate, an equity risk premium, an industry risk premium and a size premium as set forth in the Kroll Cost of Capital Navigator as of July 16, 2025. This resulted in a discount rate of 14.20% used as the midpoint of the five-point range of discount rates of 13.20% to 15.20%. Centre's annual dividends were discounted over the projection period and the total discounted value was added to the discounted terminal value to determine the total present value of Centre. The sum of the discounted value of the annual dividends plus the present value of Centre's terminal value resulted in implied total values between $131.2 million and $157.4 million with a midpoint of $143.8 million compared to the assumed total merger value of $168.0 million.

[**TABLE OF CONTENTS**](#TOC)

In the DCF Terminal P/TBV Multiple analysis, an estimated value per share of Centre common stock was calculated based on the present value of Centre's forward-looking tangible common equity and dividends over the five-year projection period of the financial forecasts provided by Centre management. The projected tangible common equity amount for the year ended 2029 was $138.7 million, which resulted in the projected adjusted tangible book value of $138.7 million and projected excess tangible book value of $0 for the year ended 2029 that served as the basis of the terminal values in the DCF. For purposes of the analysis, projected adjusted tangible book value was assumed to be equal to total tangible assets multiplied by 8.0%, and projected excess tangible book value was assumed to be equal to the projected tangible book value in excess of the projected adjusted tangible book value. In arriving at the terminal value at the end of 2029, Hovde applied a five-point range of price-to-adjusted tangible book value multiples of 1.30x to 1.50x utilizing as a midpoint of the range the median price-to-adjusted tangible book value multiple derived from transactions in the Terminal Regional Group of 1.40x and assumed dollar-for-dollar payment of excess tangible book value. The present value of the projected terminal value was then calculated assuming the range of discount rates between 13.20% and 15.20%, with a midpoint of 14.20% discounted over the same periods as was applied in the DCF Terminal P/E Multiple analysis set forth above. Centre's annual dividends were discounted over the projection period and the total discounted value was added to the discounted terminal value to determine the total present value per share of Centre common stock. The sum of the discounted value of the annual dividends plus the present value of Centre's terminal value resulted in implied values between $109.4 and $133.6 million with a midpoint of $121.1 million compared to the assumed value of the merger consideration from the merger of $168.0 million.

While the discounted cash flow present value analysis is a widely used valuation methodology, it relies on numerous assumptions, including asset and earnings growth rates, projected dividend payouts, terminal values and discount rates. Hovde's analysis does not purport to be indicative of the actual values or expected total values of Centre.

#### Certain Unaudited Prospective Financial Information of Centre
Centre does not as a matter of course make public projections as to future sales, earnings, or other results. In connection with the merger, however, Centre's management prepared certain prospective financial information to present certain unaudited prospective financial information regarding Centre's future operations for the years 2025 through 2029 (which we refer to as the "Centre projections"). This prospective financial information was not prepared with a view toward public disclosure or with a view toward complying with recognized accounting standards or guidelines, but, in the view of the Centre's management, was prepared on a reasonable basis, reflects the best currently available estimates and judgments and presents, to the best of management's knowledge and belief, the expected course of action and the expected future financial performance of Centre. However, this information is not fact and should not be relied upon as being necessarily indicative of actual future results, and readers of this proxy statement/prospectus are cautioned not to place undue reliance on the prospective financial information.

Neither Centre's independent auditors, nor any other independent accountants, have compiled, examined, or performed any procedures with respect to the prospective financial information contained herein, nor have they expressed any opinion or any other form of assurance on such information or its achievability, and assume no responsibility for, and disclaim any association with, the prospective financial information.

The Centre projections, which were prepared by Centre's management, were prepared solely for internal use and are subjective in many respects. The Centre projections reflect numerous estimates and assumptions made with respect to business, economic, market, competition, regulatory and financial conditions and matters specific to the business of Centre, all of which are difficult to predict and many of which are beyond the control of Centre. The Centre projections reflect assumptions as to certain business decisions that are subject to change and, in many respects, subjective judgment, and thus are susceptible to multiple interpretations and periodic revisions based on actual experience and business developments. Centre can give no assurance that the Centre projections and the underlying estimates and assumptions will be realized. In addition, because the Centre projections cover multiple years, the information by its nature becomes less predictive with each successive year. Actual results may differ materially from those set forth below, and important factors that may affect actual results and cause the Centre projections not to be realized include, but are not limited to, risks and uncertainties relating to the business of Centre, industry performance, general business and economic conditions, customer requirements, competition and adverse changes in applicable laws, regulations or policies. Other factors that could cause actual results to differ are further described under the headings "Risk Factors" and "Special Cautionary Note Regarding Forward-Looking Statements."

Furthermore, the Centre projections do not take into account any circumstances or events occurring after the date they were prepared. Centre can give no assurance that, had the Centre projections been prepared as of the date of this proxy statement/prospectus or any later date, similar estimates and assumptions would be used. Neither Centre nor Bank First intend to, and each disclaims any obligation to, make publicly available any update or other revision to the Centre projections to reflect circumstances existing since their preparation or to reflect the occurrence of unanticipated events, even in the event that any or all of the underlying assumptions are shown to be in error, or to reflect changes in general economic or industry conditions. The Centre projections do not give effect to the impact of negotiating or executing the merger agreement, the expenses that may be incurred in connection with consummating the merger, the effect of any business or strategic decision or action that has been or will be taken as a result of the merger agreement having been executed, or the effect on Centre of any business or strategic decisions or actions that would likely have been taken if the merger agreement had not been executed, but which were instead altered, accelerated, postponed or not taken in anticipation of the merger. Further, the Centre projections do not take into account the effect of any possible failure of the merger to occur. None of Centre, Bank First or their respective affiliates, officers, directors, advisors or other representatives has made, makes or is authorized in the future to make any representation to any shareholder of Centre or Bank First, or any other person, regarding Bank First's actual performance compared to the information contained in the Centre projections or that projected results will be achieved.

[**TABLE OF CONTENTS**](#TOC)

In light of the foregoing and considering that the Centre special meeting will be held several months after the Centre projections were prepared, as well as the uncertainties inherent in any forecasted information, shareholders of Centre are cautioned not to place unwarranted reliance on such information in connection with their consideration of the merger and the merger agreement.

The following prospective financial information was approved by Centre's management for use by Hovde in connection with Hovde performing its financial analyses with respect to Centre on a standalone basis:

#### Board Composition and Management of Bank First after the Merger
Each of the officers and directors of Bank First immediately prior to the effective time of the merger will be the officers and directors of the surviving company from and after the effective time of the merger, until their respective successors have been duly elected, appointed or qualified or until their earlier death, resignation or removal in accordance with the articles of incorporation and bylaws of Bank First, *provided, however*, each of Bank First and Bank First, N.A. will increase the size of its respective board of directors by one, and Steven M. Eldred will be appointed as a director of Bank First and Bank First, N.A., respectively.

Additionally, Bank First will consider appointing one additional member of Centre's board of directors (the "Centre director") to the Bank First board after consulting with Centre. If Bank First decides to proceed with such appointment, it will take all necessary steps to increase the size of its board of directors and appoint the Centre director as of the effective time of the merger. This appointment is subject to the Centre director meeting Bank First's director qualifications, complying with Bank First's corporate governance policies, and qualifying as an "independent director" under Nasdaq rules.

Information regarding the executive officers and directors of Bank First is contained in documents filed by Bank First with the SEC and incorporated by reference into this proxy statement/prospectus, including Bank First's Annual Report on Form 10-K for the year ended [December 31, 2024](https://www.sec.gov/ix?doc=/Archives/edgar/data/1746109/000155837025001937/bfc-20241231x10k.htm) and its definitive proxy statement on Schedule 14A for its 2025 annual meeting, filed with the SEC on [February 28, 2025](https://www.sec.gov/ix?doc=/Archives/edgar/data/1746109/000155837025001937/bfc-20241231x10k.htm) and [April 25, 2025](https://www.sec.gov/ix?doc=/Archives/edgar/data/1746109/000110465925039401/tm252417-2_def14a.htm), respectively. See "Where You Can Find More Information" and "Additional Information."

#### Interests of Centre's Directors and Executive Officers in the Merger
In considering the recommendation of the Centre board of directors to approve and adopt the merger agreement, Centre shareholders should be aware that Centre's directors and executive officers have interests in the merger that may be different from, or in addition to, the interests of Centre shareholders generally. The Centre board of directors was aware of these interests and considered them, among other matters, in evaluating and negotiating the merger agreement, in reaching its decision to approve the merger agreement and the transactions contemplated thereby (including the merger), and in recommending to Centre shareholders that the Centre merger proposal be approved and adopted. These interests include those described below.

For purposes of this compensation-related disclosure, Centre's executive officers are Steven Eldred — Chairman & CEO; Donald O'Day — President; and Gerald Ritzert — Chief Financial Officer.

 *Executive Agreements* 

Centre entered into various agreements with, and provides certain benefits to, its executive officers which provide the executives with the opportunity for severance protection and other benefits in connection with a change in control. These agreements are sometimes collectively referred to herein as the "Executive Agreements."

------

[**TABLE OF CONTENTS**](#TOC)

Centre is a party to employment agreements with Messrs. Eldred, O'Day, and Ritzert. Pursuant to the employment agreements for Messrs. O'Day and Ritzert, if either executive is terminated without "cause" or resigns for "good reason" within six months prior to or 24 months following a change in control, he will be entitled to severance in an amount equal to a multiple of the three-year average of the sum of the executive's annual base salary and annual incentive bonus, payable in a lump sum, and COBRA continuation coverage, at the current employee rate, for up to 18 months following the termination date. The multiple for Mr. O'Day is two and one-half and for Mr. Ritzert is one and one-half. Pursuant to Mr. Eldred's employment agreement, if he is terminated without "cause" or resigns for "good reason" prior to the end of his employment term, he will receive severance equal to the remainder of his base salary owed through the end of such term and will receive an additional payment with respect to his health insurance costs for up to 18 months following his termination date. Any severance payments are predicated upon receipt of a release of any claims from the employee. In addition, the executives have agreed to comply with certain restrictive covenants, including covenants regarding non-competition and non-solicitation of customers and employees that apply following termination of employment. The merger will constitute a change in control for purpose of the employment agreements.

Centre is also a party a supplemental retirement agreement with Steven Eldred (the "SERP"). The SERP provides Mr. Eldred with a specified retirement benefit in addition to what he is eligible to receive under the Company's standard retirement plans. In connection with the change in control, the SERP will be terminated and any remaining amounts will be paid to Mr. Eldred in accordance with the SERP and applicable law. The SERP includes a covenant regarding non-competition and non-solicitation of customers that apply for 12 months following Mr. Eldred's termination of employment.

First National Bank sponsors the 162(a)(1) Life Insurance Plan (the "Life Plan") pursuant to which Mr. O'Day receives certain life insurance benefits. If he is terminated without "cause" or resigns for "good reason" within 24 months following the change in control, First National Bank will increase the benefit under the Life Plan as if such Mr. O'Day remained employed through the final vesting date set forth in his award agreement. In connection with the change in control, the Life Plan will be terminated and Mr. O'Day will be entitled to such increased benefit. The merger will constitute a change in control for purpose of the Life Plan.

As of the effective time of the merger, Centre and First National Bank will transfer certain Centre- and First National Bank-owned automobiles to Messrs. Eldred, O'Day, and Ritzert.

The aggregate amount of the severance benefits under the employment agreements is $2,443,000, the liquidating payment to Mr. Eldred under the SERP is $3,170,000, the value of the increased benefit to Mr. O'Day under the Life Plan is $324,000, and the aggregate value of the automobiles is $249,000.

Centre sponsors the 2017 Long-Term Incentive Plan (the "2017 LTIP") pursuant to which Messrs. Eldred, O'Day, and Ritzert were granted certain time-based and performance-based restricted stock units. Immediately prior to the effective time of the merger, each award of time-based and performance-based restricted stock units granted under the 2017 LTIP that is outstanding immediately prior to the effective time of the merger will become fully vested and be settled and be converted into the right to receive the merger consideration with respect to the total number of shares of Centre's common stock subject to such restricted stock units as of immediately prior to the effective time of the merger (assuming target level performance for the performance-based restricted stock units). The aggregate payout of the restricted stock units to the executive officers participating in the 2017 LTIP, assuming that the completion of the merger occurs on September 25, 2025, and that the per share cash equivalent consideration at the effective time of the merger is $114.19, is anticipated to be approximately $644,490.62.

 *First National Bank and Trust Directors Deferred Compensation Plan* 

First National Bank sponsors the Directors Deferred Compensation Plan (the "Bank DCP") pursuant to which Gregory Britton, Timothy McKevett, William DeLong, and Roger Kenman, who are either current or former directors of Centre, participate. As of the effective time, the Bank DCP will be terminated and the entire unpaid balance of each individual's accounts under the Bank DCP will be distributed to him in a lump sum. As of June 30, 2025, the aggregated unpaid balance under the Bank DCP was $1,291,366.

 *Mr. Eldred's Appointment to the Board of Directors of Bank First and Bank First, N.A.* 

Bank First and Bank First, N.A. each has agreed to take all actions necessary so that, as of the effective time of the merger, the number of directors constituting the Bank First board of directors and Bank First, N.A. board of directors shall be increased by one and Steven M. Eldred shall be appointed as director of each entity, *provided that* Mr. Eldred meets Bank First's and Bank First, N.A.'s standards for directors, complies with Bank First's corporate governance policies, and qualifies as an "independent director" under Nasdaq rules. Mr. Eldred will also be appointed to the board of directors of Bank First, N.A.

 *Compensation Arrangements with Bank First* 

Mr. Eldred intends to enter into a consulting agreement with Bank First upon the closing of the merger, under which Mr. Eldred will receive compensation from Bank First for a period of two years, in exchange for providing ongoing services related to the transition of First National Bank's and/or Centre's clients, employees, impacted communities, vendors, and other interested parties; successful system conversions; and other matters to ensure smooth transition of ownership to Bank First.

It is possible that other employees will enter into new compensation agreements, arrangements or understandings with Bank First. As of September 25, 2025, Centre is not aware of any compensation agreements, arrangements or understandings between its executive officers other than Mr. Eldred and Bank First.

 *Indemnification of Directors and Officers* 

Bank First has agreed to maintain in effect a directors' and officers' liability insurance policy for a period of six years after the effective time of the merger with respect to claims arising from facts, events or actions that occurred prior to the effective time of the merger and covering persons who are currently covered by such insurance. The insurance policy must contain at least the same coverage and amounts and contain terms and conditions no less advantageous to the directors and officers as currently provided, subject to a cap on the cost of such policy equal to 100% of the last annual premium paid by Centre. For a period of six years following the effective time, to the extent permitted by applicable law, Bank First has agreed to indemnify and hold harmless the present and former directors and officers of Centre and its subsidiaries for all actions or omissions of such persons in the course of performing their duties to Centre and its subsidiaries which occurred at or prior to the effective time of the merger.

#### Regulatory Approvals Required for the Merger
Completion of the merger is subject to prior receipt of all approvals required to be obtained from applicable governmental and regulatory authorities. Subject to the terms and conditions of the merger agreement, Centre and Bank First have agreed to use their reasonable best efforts and cooperate to prepare and file, as promptly as possible, all necessary documentation and to obtain as promptly as practicable all regulatory approvals or waivers required or advisable to complete the transactions contemplated by the merger agreement. These approvals and waivers include, among others, a waiver from the Federal Reserve Board and an approval from the OCC and the WDFI. Bank First and/or Centre have filed applications, waiver requests and notifications to obtain the required regulatory approvals or waivers.

------

[**TABLE OF CONTENTS**](#TOC)

 *Federal Reserve Board* 

The merger of Centre with Bank First must be approved by the Federal Reserve Board under Section 3 of the Bank Holding Company Act of 1956, or the BHC Act, and its implementing regulations, unless the Federal Reserve Board waives the application requirements of the BHC Act. In considering the approval of a transaction such as the merger, the BHC Act and related laws require the Federal Reserve Board to review, with respect to the parent holding companies and the bank concerned: (1) the competitive impact of the transaction; (2) financial, managerial and other supervisory considerations, including capital positions and managerial resources of the subject entities; (3) the record of the insured depository institution subsidiaries of the bank holding companies under the Community Reinvestment Act, or the CRA, and fair lending laws; (4) the extent to which the proposal would result in greater or more concentrated risks to the stability of the U.S. banking or financial system; and (5) additional public benefits of the proposal, such as the benefits to the customers of the subject entities. In connection with its review, the Federal Reserve Board will provide an opportunity for public comment on the application and is authorized to hold a public meeting or other proceeding if it determines that would be appropriate. Bank First filed a written request that the Federal Reserve Board waive the application requirements of the BHC Act with regard to its acquisition of Centre on August 15, 2025.

 *Office of the Comptroller of the Currency* 

The merger of First National Bank with and into Bank First, N.A. must be approved by the OCC under the National Bank Consolidation and Merger Act, 12 U.S.C. 215, 215a, commonly known as the Bank Merger Act. In evaluating an application filed under the Bank Merger Act, the OCC generally considers: (1) the competitive impact of the transaction; (2) financial and managerial resources of the banks who are parties to the bank merger or merger; (3) the convenience and needs of the community to be served and the record of the banks under the CRA; (4) the banks' effectiveness in combating money-laundering activities; and (5) the extent to which the bank merger or merger would result in greater or more concentrated risks to the stability of the U.S. banking or financial system. The OCC may modify, suspend or rescind its approval if a material change in the information on which the OCC relied occurs prior to completion of the merger. In connection with its review, the OCC will provide an opportunity for public comment on the application for the bank merger and is authorized to hold a public meeting or other proceeding if they determine that would be appropriate. An application for approval of the bank merger was filed with the OCC on August 15, 2025.

 *WDFI* 

In addition to the required approvals of the Federal Reserve Board and OCC discussed above, the merger also requires the approval of the WDFI. Bank First filed an application with the WDFI on August 15, 2025 pursuant to Section 221.0901 of Wisconsin banking law. In evaluating the application, the WDFI must consider various aspects of the proposed transaction and the parties thereto, including, among others, the financial and managerial resources and future prospects of the institutions involved, the best interests of their shareholders and customers, safety and soundness considerations, and the CRA compliance status of each bank. The relevant statutes prohibit the WDFI from approving the transaction if, following consummation, the combined institution would control more than 30 percent of the deposits in the state.

 *General* 

The U.S. Department of Justice has between 15 and 30 days following approvals by the Federal Reserve and OCC to challenge the approval on antitrust grounds. There can be no assurance that the Department of Justice will not initiate a proceeding to challenge regulatory approval by the Federal Reserve and the OCC, and if such a proceeding is initiated, as to the result of any such challenge.

In connection with or as a result of the merger, Bank First and Centre may be required, pursuant to other laws and regulations, either to notify or obtain the consent of other regulatory authorities and organizations to which such companies or subsidiaries of either or both of them may be subject. The Bank First common stock to be issued in exchange for Centre common stock in the merger will be registered with the SEC and will be issued pursuant to available exemptions from registration under state securities law.

------

[**TABLE OF CONTENTS**](#TOC)

The approval of any notice or application merely implies satisfaction of regulatory criteria for approval and does not include review of the merger from the standpoint of the adequacy of the consideration to be received by, or fairness to, shareholders. Regulatory approval does not constitute an endorsement or recommendation of the proposed merger.

Bank First and Centre believe that the merger does not raise substantial antitrust or other significant regulatory concerns and that Centre will be able to obtain all requisite regulatory approvals. However, neither Bank First nor Centre can assure you that all of the regulatory approvals described above will be obtained and, if obtained, neither Bank First nor Centre can assure you as to the timing of any such approvals, our ability to obtain the approvals on satisfactory terms or the absence of any litigation challenging such approvals. The parties have agreed that Bank First will not be required, and Centre and its subsidiaries will not be permitted, to take any action or commit to take any action or agree to any condition or restrictions in connection with the regulatory approvals that, individually or in the aggregate, would have or would be reasonably likely to have a material adverse effect on Bank First and its subsidiaries or Centre and its subsidiaries as of and following the completion of the merger.

The parties' obligation to complete the merger is conditioned upon the receipt of all required regulatory approvals. Bank First and Centre will use their respective commercially reasonable efforts to resolve any objections that may be asserted by any regulatory authority with respect to the merger agreement or the merger or the other transactions contemplated by the merger agreement.

Neither Bank First nor Centre is aware of any material governmental approvals or actions that are required for completion of the merger other than those described above. It is presently contemplated that if any such additional governmental approvals or actions are required, those approvals or actions will be sought. There can be no assurance, however, that any additional approvals or actions will be obtained.

#### Accounting Treatment
The merger will be accounted for under the acquisition method of accounting for business combinations under GAAP. Under this method, Centre's assets and liabilities as of the date of the merger will be recorded at their respective fair values. Any difference between the purchase price for Centre and the fair value of the identifiable net assets acquired (including core deposit intangibles) will be recorded as goodwill. In accordance with ASC Topic 805, "*Business Combinations*," the goodwill resulting from the merger will not be amortized to expense but instead will be reviewed for impairment at least annually and to the extent goodwill is impaired, its carrying value will be written down to its implied fair value and a charge will be made to earnings. Core deposit and other intangibles with definite useful lives recorded by Bank First in connection with the merger will be amortized to expense in accordance with such rules. The consolidated financial statements of Bank First issued after the merger will reflect the results attributable to the acquired operations of Centre beginning on the date of completion of the merger.

#### Dissenters' Rights
The following discussion is not a complete description of the law relating to dissenters' rights available to holders and beneficial holders of Centre and Bank First common stock under Wisconsin law. This description is qualified in its entirety by the full text of the relevant provisions of the WBCL, which are reprinted in their entirety as <u>Annex B</u> to this proxy statement/prospectus. If you desire to exercise dissenters' rights, you should review carefully the WBCL and consult a legal advisor before electing or attempting to exercise these rights.

 *General* 

Pursuant to the provisions of sections 180.1301 to 180.1331 of the WBCL, holders and beneficial holders of Centre common stock have the right to dissent from the merger and to receive the fair value of their shares in cash. Holders and beneficial holders of Centre common stock who fulfill the requirements of the WBCL summarized below and set forth in <u>Annex B</u> will be entitled to assert dissenters' rights in connection with the merger. Shareholders or beneficial shareholders considering initiation of a dissenters' proceeding should review this section and should also review <u>Annex B</u> in its entirety. A dissenters' proceeding may involve litigation.

------

[**TABLE OF CONTENTS**](#TOC)

 *Preliminary Procedural Steps* 

Pursuant to the provisions of the WBCL, if the merger is consummated, in order to exercise dissenter's rights you must have:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • given to Centre, prior to the vote at the Centre special meeting with respect to the approval of the merger, written notice of your intent to demand payment for your shares of common stock (hereinafter referred to as "shares");

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • not voted in favor of the merger; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • complied with the other statutory requirements summarized below.

If you have perfected your dissenters' rights and the merger is consummated, you will receive the fair value of your shares as of the effective date of the merger. A shareholder or beneficial shareholder who fails to deliver written notice of his, her or its intent to demand payment for his, her or its shares if the merger is consummated in accordance with the requirements of the WBCL is not entitled to payment for his, her or its shares pursuant to the provisions of the WBCL and will only be entitled to receive the merger consideration as provided in the merger agreement.

Brokers or others who hold shares in their name that are beneficially owned by others may assert dissenters rights as to fewer than all of the shares registered in your name only if they dissent with respect to all shares beneficially owned by any one person and notify Centre in writing of the name and address of each person on whose behalf they are asserting dissenters' rights. The rights of a shareholder who asserts dissenters' rights as to fewer than all of the shares registered in his, her or its name are determined as if the shares as to which that holder dissents and that holder's other shares were registered in the names of different shareholders. A beneficial shareholder may assert dissenters' rights as to shares held on his or her behalf only if the beneficial shareholder submits a written consent to Centre to the dissent not later than the time that the beneficial shareholder asserts dissenters' rights, and the beneficial shareholder submits the consent with respect to all shares of which he, she or it is the beneficial shareholder.

 *Written Dissent Demand* 

Voting against the merger will not independently satisfy the written demand requirement. In addition to not voting in favor of the merger, if you wish to preserve the right to dissent and seek appraisal, you must give a separate written notice of your intent to demand payment for your shares if the merger is effected. Any written notice of intent to dissent to the merger, satisfying the requirements discussed above, should be addressed to Centre 1 Bancorp, Inc., 345 East Grand Avenue, Beloit, WI 53511 Attn: Christy M. Farmer. The written notice must be delivered to Centre prior to the Centre special meeting.

 *Dissenters' Notice* 

If the shareholders of Centre approve the merger at the Centre special meeting, Centre (or Bank First as its successor) must deliver a written dissenters' notice (the "Dissenters' Notice") to all Centre shareholders who satisfy the foregoing requirements. The Dissenters' Notice must be sent no later than ten days after the date that the merger is approved by Centre's shareholders and must:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • state where dissenting shareholders should send the demand for payment and where and when dissenting shareholders should deposit certificates for the shares;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • inform holders of uncertificated shares as to what extent transfer of these shares will be restricted after the demand for payment is received;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • include a form for demanding payment that includes the date of the first announcement to news media or to shareholders of the terms of the merger and requires the shareholder or beneficial shareholder asserting dissenters' rights to certify whether he, she or it acquired beneficial ownership of the shares prior to that date;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • set a date by which Centre (or Bank First as its successor) must receive the demand for payment (which date may not be fewer than 30 nor more than 60 days after the Dissenters' Notice is delivered); and

------

[**TABLE OF CONTENTS**](#TOC)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • be accompanied by a copy of sections 180.1301 to 180.1331 of the WBCL.

A shareholder or beneficial shareholder who receives the Dissenters' Notice or a beneficial shareholder whose shares are held by a nominee who is sent a Dissenters' Notice must demand payment and certify as to his or her ownership of the shares in accordance with the Dissenters' Notice. A shareholder or beneficial shareholder who holds certificated shares must also deposit his, her or its share certificates with Centre (or Bank First as its successor) in accordance with the terms of the Dissenters' Notice.

A dissenting shareholder or beneficial shareholder who demands payment and deposits his, her or its share certificate in accordance with the terms of the Dissenters' Notice will retain all of the rights of a shareholder or beneficial shareholder, respectively, until those rights are canceled or modified by the consummation of the merger. Centre may restrict the transfer of uncertificated shares from the date that the demand for payment for those shares is received until the merger is effected or the restrictions released, in the event that it does not consummate the merger.

A shareholder or beneficial shareholder with certificated or uncertificated shares who does not demand payment by the date set forth in the Dissenters' Notice is not entitled to payment for his, her or its shares under sections 180.1301 to 180.1331 of the WBCL. A shareholder or beneficial shareholder with certificated shares who does not deposit his, her or its share certificates where required and by the date set forth in the Dissenters' Notice is not entitled to payment for his, her or its shares under sections 180.1301 to 180.1331 of the WBCL. Centre (or Bank First as its successor) may elect to withhold payment from a dissenter and instead make an offer of payment if that dissenter was not the beneficial owner of his, her or its shares prior to the date specified in the Dissenters' Notice as the date on which the first announcement of the merger was made to the news media or to Centre's shareholders.

 *Payment* 

Except as described below, Centre (or Bank First as its successor) must, as soon as the merger is effected or upon receipt of a payment demand, whichever is later, pay each shareholder who has complied with the payment demand and deposit requirements described above the amount Centre (or Bank First as its successor) estimates to be the fair value of the shares, plus accrued interest. The offer of payment must be accompanied by:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • recent financial statements of Centre;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • a statement of the estimate of the fair value of the shares;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • an explanation of how the interest was calculated;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • a statement of the dissenter's right to demand payment under section 180.1328 of the WBCL if the dissenter is dissatisfied with the payment; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • a copy of sections 180.1301 to 180.1331 of the WBCL.

If the merger is not consummated within 60 days after the date set for demanding payment and depositing share certificates, Centre must return the deposited certificates and release the transfer restrictions imposed on uncertificated shares. Centre (or Bank First as its successor) must send a new Dissenters' Notice if the merger is consummated after the return of certificates and any dissenting shareholders must repeat the payment demand procedure described above.

Section 180.1328 of the WBCL provides that a dissenter may notify Centre (or Bank First as its successor) in writing of his, her or its own estimate of the fair value of such holder's shares and the interest due, and may demand payment of such holder's estimate, less any payment received from Centre (or Bank First as its successor), if:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • he or she believes that the amount paid or offered by Centre (or Bank First as its successor) is less than the fair value of his or her shares or that Centre (or Bank First as its successor) has calculated incorrectly the interest due;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Centre (or Bank First as its successor) fails to make payment within 60 days after the date set in the Dissenters' Notice for demanding payment; or

[**TABLE OF CONTENTS**](#TOC)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Centre, having failed to consummate the merger, does not return the deposited certificates or release the transfer restrictions imposed on uncertificated shares within 60 days after the date set for demanding payment in the Dissenters' Notice.

A dissenting shareholder waives his, her or its right to demand payment of his, her or its own estimate of fair value and interest under sections 180.1328 unless such dissenting shareholder provides Centre (or Bank First as its successor) with notice of his, her or its demand, in conformance with the notice requirements of section 180.0141 of the WBCL, within 30 days after Centre's (or Bank First as its successor) making or offering of payment for the dissenting shareholder's shares.

 *Litigation* 

If a demand for payment under section 180.1328 of the WBCL remains unsettled, Centre (or Bank First as its successor) must commence a nonjury equity valuation proceeding in the Circuit Court of Rock County, Wisconsin (in the case of Centre) or Manitowoc County, Wisconsin (in the case of Bank First), within 60 days after having received the payment demand under section 180.1328 of the WBCL and must petition the court to determine the fair value of the shares and accrued interest. If Centre (or Bank First as its successor) does not commence the proceeding within those 60 days, the WBCL requires Centre (or Bank First as its successor) to pay each dissenting shareholder whose demand remains unsettled the amount demanded. Centre (or Bank First as its successor) is required to make all dissenting shareholders whose demands remain unsettled parties to the proceeding and to serve a copy of the petition upon each of them.

The jurisdiction of the court in which the proceeding is brought is plenary and exclusive. The court may appoint one or more appraisers to receive evidence and to recommend a decision on fair value. An appraiser has the powers delegated to such appraiser in the court order appointing him or her or in any amendment to the order. Dissenters are entitled to the same discovery rights as parties in other civil proceedings.

Each dissenting shareholder made a party to the proceeding is entitled to judgment for the amount, if any, by which the court finds the fair value of such holder's shares, plus interest, exceeds the amount paid or offered, as applicable, by Centre (or Bank First as its successor).

The court in an appraisal proceeding commenced under the foregoing provision must determine the costs of the proceeding, excluding fees and expenses of attorneys and experts for the respective parties, and must assess those costs against Centre (or Bank First as its successor), except that the court may assess the costs against all or some of the dissenting shareholders to the extent the court finds they acted arbitrarily, vexatiously, or not in good faith in demanding payment under section 180.1328 of the WBCL. The court also may assess the fees and expenses of attorneys and experts for the respective parties against Centre (or Bank First as its successor) if the court finds Centre (or Bank First as its successor) did not substantially comply with the requirements of the WBCL, or against either Centre (or Bank First as its successor) or a dissenting shareholder if the court finds that such party acted arbitrarily, vexatiously, or not in good faith with respect to the rights provided by the WBCL.

If the court finds that the services of attorneys or experts for any dissenter were of substantial benefit to other dissenters similarly situated, the court may award those attorneys' reasonable fees out of the amounts awarded the dissenters who were benefited.

This is a summary of the material rights of a dissenting shareholder and is qualified in its entirety by reference to the applicable portions of the WBCL, which are included as <u>Annex B</u> to this proxy statement/prospectus. If you intend to dissent from approval of the merger, you should review carefully the text of <u>Annex B</u> and should also consult with your attorney. We will not give you any further notice of the events giving rise to dissenters' rights or any steps associated with perfecting dissenters' rights, except as indicated above or otherwise required by law.

We have not made any provision to grant you access to any of the corporate files of Bank First or Centre, except as may be required by the WBCL, or to obtain legal counsel or appraisal services at the expense of Centre (or Bank First as its successor).

------

[**TABLE OF CONTENTS**](#TOC)

Any dissenting shareholder who perfects his, her or its right to be paid the "fair value" of his, her or its shares will recognize taxable gain or loss upon receipt of cash for such shares for federal income tax purposes. See "Material U.S. Federal Income Tax Consequences of the Merger" at page [131](#tMUFI).

 **You must do all of the things described in this section and as set forth in the WBCL to preserve your dissenters' rights and to receive the fair value of your shares in cash (as determined in accordance with those provisions). If you do not follow each of the steps described above, you will have no right to receive cash for your shares as provided in the WBCL and you will only be entitled to receive the merger consideration as provided in the merger agreement. In view of the complexity of these provisions of Wisconsin law, shareholders of Centre who are considering exercising their dissenters' rights should consult their legal advisors.** 

 *Certain U.S. Federal Income Tax Consequences* 

See "Material U.S. Federal Income Tax Consequences of the Merger" beginning on page [131](#tMUFI) for a discussion on how the material federal income tax consequences of the merger will change if you elect to exercise dissenters' rights in the merger.

The above description is a summary of the material provisions of Subchapter XIII of the WBCL. For complete information, you should review the text of those sections, which appear as <u>Annex B</u> to this proxy statement/prospectus.

#### Exchange of Shares in the Merger
The conversion of Centre common stock into the right to receive the merger consideration will occur automatically at the effective time of the merger. After completion of the merger, the exchange agent will exchange certificates representing shares of Centre common stock for the merger consideration to be received pursuant to the terms of the merger agreement. For more information regarding the procedures for exchanging your shares of Centre common stock for the merger consideration, see "The Merger Agreement — Procedures for Converting Shares of Centre Common Stock into Merger Consideration" below.

#### Listing of Bank First Common Stock
Bank First has agreed to use its commercially reasonable efforts to cause the shares of Bank First common stock issuable in connection with the merger be approved for listing on the Nasdaq Capital Market subject to official notice of issuance, prior to the effective time of the merger.

#### THE MERGER AGREEMENT
 *The following describes certain aspects of the merger, including certain material provisions of the merger agreement. The following description of the merger agreement is subject to, and qualified in its entirety by reference to, the merger agreement, which is attached to this proxy statement/prospectus as <u>Annex A</u> and is incorporated by reference into this proxy statement/prospectus. We urge you to read the merger agreement carefully and in its entirety, as it is the legal document governing the merger.* 

#### Structure of the Merger
The boards of directors of Bank First and Centre have each unanimously approved the merger agreement, which provides for the merger of Centre with and into Bank First, with Bank First as the surviving company in the merger.

The merger agreement also provides that immediately after the effective time of the merger but in effect simultaneously on the date the merger closes, First National Bank, which is a national banking association and a direct wholly-owned subsidiary of Centre, will merge with and into Bank First, N.A., a national banking association and a direct wholly-owned subsidiary of Bank First, with Bank First, N.A. as the surviving bank of such merger. The terms and conditions of the merger of Bank First, N.A. and First National Bank are set forth in a separate bank plan of merger and merger agreement, referred to as the bank merger agreement, the form of which is attached as Exhibit B to the merger agreement. As provided in the bank merger agreement, the merger of Bank First, N.A. and First National Bank may be abandoned at the election of Bank First, N.A. at any time, whether before or after filings are made for regulatory approval of such merger. We refer to the merger of Bank First, N.A. and First National Bank as the bank merger.

The merger agreement allows Bank First to change the structure of the merger at any time and without the approval of Centre if and to the extent that Bank First reasonably deems such a change to be necessary; *provided, however*, that no such change shall (i) alter or change the amount of merger consideration to be provided under the merger agreement, (ii) reasonably be expected to materially impede or delay consummation of the merger, (iii) adversely affect the federal income tax treatment of Centre shareholders in connection with the merger, or (iv) require submission to or the approval of Centre shareholders after the Centre merger proposal has already been approved by Centre's shareholders. In the event of such election, the parties agree to execute an appropriate amendment to the agreement to reflect such election.

#### Closing and Effective Time of the Merger
The closing will take place on the business day prior to the effective time of the merger. The effective time of the merger will be the later of (i) the date and time of filing of the articles of merger with the WDFI by Bank First or (ii) the date and time when the merger becomes effective as set forth in such articles of merger, which will be such date and time as the parties may mutually agree, but in no event later than January 1, 2026, subject to the satisfaction of the closing conditions set forth in the merger agreement.

We currently expect that the merger will be completed in the first quarter of 2026, subject to obtaining the requisite approval from the shareholders of Centre, the receipt of all necessary regulatory approvals, and the expiration of all regulatory waiting periods and other conditions. However, completion of the merger could be delayed if there is a delay in obtaining the required regulatory approvals or in satisfying any other conditions to the merger. No assurance is made as to whether, or when, Bank First and Centre will obtain the required approvals or complete the merger. See "The Merger Agreement — Conditions to Complete the Merger."

#### Organizational Documents of the Surviving Company
At the effective time of the merger, Bank First Articles and Bank First Bylaws in effect immediately prior to the effective time of the merger will be the articles of incorporation and bylaws of the surviving company until thereafter amended in accordance with their respective terms and applicable laws.

------

[**TABLE OF CONTENTS**](#TOC)

#### Board Composition and Management of Surviving Company
Each of the officers and directors of Bank First immediately prior to the effective time of the merger will be the officers and directors of the surviving company from and after the effective time of the merger, until their respective successors have been duly elected, appointed or qualified or until their earlier death, resignation or removal in accordance with the articles of incorporation and bylaws of Bank First, *provided, however*, that Steven M. Eldred will be appointed as a director of both Bank First and Bank First, N.A.

Additionally, Bank First will consider appointing one additional member of Centre's board of directors (the "Centre director") to the Bank First board after consulting with Centre. If Bank First decides to proceed with such appointment, it will take all necessary steps to increase the size of its board of directors and appoint the Centre director as of the effective time of the merger. This appointment is subject to the Centre director meeting Bank First's director qualifications, complying with Bank First's corporate governance policies, and qualifying as an "independent director" under Nasdaq rules.

#### Merger Consideration
Under the terms of the merger agreement, at the effective time of the merger, each share of Centre common stock issued and outstanding immediately prior to the effective time of the merger will be converted into the right to receive 0.9200 of a share (the "exchange ratio") of Bank First common stock (the "merger consideration"). Each outstanding share of Bank First's common stock will remain outstanding and unaffected by the merger.

The merger consideration is also subject to a downward adjustment based on Centre's tangible book value at closing. If Centre's tangible book value (as calculated per the merger agreement) is less than $83,587,000 (which we refer to as the "minimum Centre tangible book value") at the time of the closing of the merger, then the merger consideration will be adjusted downward by an amount that is reflective of the overall shortfall between the minimum Centre tangible book value and Centre's tangible book value at closing.

Bank First will not issue any fractional shares of Bank First common stock in the merger. Instead, a Centre shareholder who otherwise would have received a fraction of a share of Bank First common stock will receive an amount in cash (without interest and rounded to the nearest cent) determined by multiplying (1) the per share volume weighted average price of Bank First common stock as reported on the Nasdaq Capital Market during the ten consecutive trading days immediately prior to the fifth trading day prior to closing by (2) the fraction of a share (rounded to the nearest one hundredth of a share) of Bank First common stock to which such shareholder would otherwise be entitled to receive.

If Bank First or Centre change the number of shares of Bank First common stock or Centre common stock outstanding prior to the effective time of the merger as a result of a stock split, reverse stock split, stock combination, stock dividend, recapitalization, reclassification, reorganization or similar transaction with respect to Bank First common stock or Centre common stock and the record date for such corporate action is prior to the effective time of the merger, then the merger consideration shall be appropriately and proportionately adjusted to give Centre shareholders the same economic effect as contemplated by the merger agreement prior to any such event.

The value of the shares of Bank First common stock to be issued to Centre shareholders in the merger will fluctuate between now and the closing date of the merger. We make no assurances as to whether or when the merger will be completed, and you are advised to obtain current sale prices for the Bank First common stock.

#### Treatment of Centre Equity Awards

#### Treatment of Centre Options
At the effective time of the merger, each outstanding option to purchase shares of Centre common stock granted under any Centre stock plan (each, a "Centre Option"), whether vested or unvested, will become fully vested and be automatically cancelled, without any required action by the holder. In exchange for such cancellation, each Centre Option will be converted into the right to receive a cash payment, if any, equal to the product of (i) the excess, if any, of (A) the product of the exchange ratio and the average of the volume-weighted average price of Bank First common stock over the ten trading days ending on the fifth trading day prior to the closing date, *divided by* (B) the exercise price per share of the Centre Option immediately prior to the effective time *multiplied by* (ii) the total number of shares of Centre common stock subject to such Centre Option, which is referred to herein as the "per share cash equivalent consideration." Any Centre Option with an exercise price equal to or greater than the per share cash equivalent consideration will be canceled without any payment to the holder. All cash payments to holders of Centre Options will be made as promptly as practicable following the effective time of the merger, and in any event no later than five business days thereafter, subject to applicable tax withholding and without interest.

#### Treatment of Restricted Stock Units
Immediately prior to the effective time of the merger, each outstanding award of performance-based restricted stock units ("Centre PBRSU Awards") and time-based restricted stock units ("Centre TBRSU Awards") granted under any Centre stock plan will automatically become fully vested and be settled, without any required action by the holder. Each Centre PBRSU Award will be settled based on the target level of performance, and both Centre PBRSU Awards and Centre TBRSU Awards will be converted into the right to receive the merger consideration for the total number of shares of Centre common stock subject to the respective award as of immediately prior to the effective time of the merger. The merger consideration will be delivered without interest and will be subject to applicable tax withholdings.

#### Procedures for Converting Shares of Centre Common Stock into Merger Consideration

#### Exchange Agent
Bank First has designated Computershare, Inc. to act as the exchange agent in connection with the merger. The exchange agent shall also act as the agent for Centre shareholders for the purpose of receiving their Centre stock certificates and shall obtain no rights or interests in the shares represented thereby. Prior to the effective time of the merger, Bank First will deposit, or cause to be deposited, with the exchange agent the merger consideration and, to the extent then determinable, any cash payable in lieu of fractional shares, necessary to satisfy the merger consideration payable.

#### Transmittal Materials and Procedures
Promptly (but not more than five business days) after the effective time of the merger, Bank First will cause the exchange agent to send transmittal materials, which will include the appropriate form of letter of transmittal, to holders of record of shares of Centre common stock (other than excluded shares) providing instructions on how to effect the delivery of certificates or book-entry shares of Centre common stock in exchange for the merger consideration. After the effective time of the merger, when a Centre common shareholder surrenders his or her stock certificates or book-entry shares, accompanied by a properly executed letter of transmittal and any other documents as may reasonably be required by the exchange agent, the holder of shares of Centre common stock will be entitled to receive, (i) the merger consideration and (ii) any cash in lieu of fractional shares to which the holder is entitled.

------

[**TABLE OF CONTENTS**](#TOC)

#### Surrender of Centre Stock Certificates
The exchange agent will mail to each holder of record of Centre common stock the letter of transmittal along with instructions for completing the letter of transmittal and delivering to the exchange agent the completed letter of transmittal along with the stock certificates or book-entry shares representing the shares of Centre common stock held by the shareholder.

Following the effective time of the merger, upon the surrender to the exchange agent of the certificate(s) or book-entry shares representing his or her shares of Centre common stock, accompanied by a properly completed letter of transmittal, a Centre shareholder will be entitled to receive the merger consideration promptly after the effective time of the merger (including any cash in lieu of fractional shares). Until surrendered, each such certificate will represent after the effective time of the merger, for all purposes, only the right to receive the merger consideration, without interest (including any cash in lieu of fractional shares), and any dividends to which such holder is entitled pursuant to the merger agreement.

No dividends or other distributions with respect to Bank First common stock after completion of the merger will be paid to the holder of any unsurrendered Centre stock certificates or book-entry shares with respect to the shares of Centre common stock represented by those certificates until those certificates or book-entry shares have been properly surrendered. Subject to applicable abandoned property, escheat or similar laws, following the proper surrender of any such previously unsurrendered Centre stock certificate or book-entry shares, the holder of the certificate or book-entry shares will be entitled to receive, without interest: (i) the amount of unpaid dividends or other distributions with a record date after the effective time of the merger payable with respect to the whole shares of Bank First common stock represented by that certificate or book-entry shares; and (ii) at the appropriate payment date, the amount of dividends or other distributions payable with respect to shares of Bank First common stock represented by that certificate or the book-entry shares with a record date after the effective time of the merger (but before the date on which the certificate or book-entry shares are surrendered) and with a payment date subsequent to the issuance of the shares of Bank First common stock issuable in exchange for that certificate or book-entry shares.

None of Bank First, the exchange agent or any other person will be liable to any former Centre shareholder for any amount delivered in good faith to a public official pursuant to applicable abandoned property, escheat or similar law.

In the event any Centre stock certificate is lost, stolen or destroyed, in order to receive the merger consideration (including cash in lieu of any fractional shares), the holder of that certificate must provide an affidavit of that fact and, if reasonably required by Bank First or the exchange agent, post a bond in such amount as Bank First or the exchange agent determines is reasonably necessary to indemnify it against any claim that may be made against it with respect to that certificate.

Bank First and the exchange agent will be entitled to deduct and withhold from the consideration otherwise payable to any Centre shareholder the amounts they are required to deduct and withhold under any applicable federal, state, local or foreign tax law. If any such amounts are withheld, these amounts will be treated for all purposes of the merger agreement as having been paid to the shareholders from whom they were withheld.

After completion of the merger, there will be no further transfers on the stock transfer books of Centre other than to settle transfers of Centre common stock that occurred prior to the effective time of the merger.

No interest will be paid or accrued on any amount payable upon cancellation of shares of Centre common stock. The shares of Bank First common stock issued and cash amount paid in accordance with the merger agreement upon conversion of the shares of Centre common stock (including any cash paid in lieu of fractional shares) will be deemed to have been issued and paid in full satisfaction of all rights pertaining to the shares of Centre common stock.

[**TABLE OF CONTENTS**](#TOC)

If any portion of the merger consideration is to be delivered to a person or entity other than the holder in whose name any surrendered certificate is registered, it will be a condition of such exchange that (i) the certificate surrendered must be properly endorsed or must be otherwise in proper form for transfer and (ii) the person or entity requesting such payment pays any transfer or other similar taxes required by reason of the payment of the merger consideration to a person or entity other than the registered holder of the certificate surrendered or will establish to the satisfaction of Bank First that such tax has been paid or is not required to be paid. Payment of the applicable merger consideration with respect to book-entry shares will only be made to the person or entity in whose name such book-entry shares are registered. The shares of Bank First common stock may be in uncertificated book-entry form, unless a physical certificate is otherwise required by any applicable law.

#### Definition of "Material Adverse Effect"
Certain representations and warranties of Bank First and Centre are qualified as to "materiality" or "material adverse effect." For purposes of the merger agreement, a "material adverse effect," when used in reference to either Bank First or Centre, means (i) any change, development or effect that individually or in the aggregate is, or is reasonably likely to be, material and adverse to the condition (financial or otherwise), results of operations, liquidity, assets or deposit liabilities, properties, or business of such party and its subsidiaries, taken as a whole, or (ii) any change, development or effect that individually or in the aggregate would, or would be reasonably likely to, materially impair the ability of such party to perform its obligations under the merger agreement or otherwise materially impairs, or is reasonably likely to materially impair, the ability of such party to consummate the merger and the transactions contemplated by the merger agreement. For purposes of clause (i) only, the definition of "material adverse effect" excludes the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • changes in banking and similar laws of general applicability or interpretations thereof by any governmental authority;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • changes in GAAP or regulatory accounting requirements applicable to banks or bank holding companies generally;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • changes in global, national or regional political conditions (including the outbreak of war or acts of terrorism) or in economic or market (including equity, credit and debt markets, as well as changes in interest rates) conditions affecting the financial services industry generally;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • public disclosure of the transactions contemplated or actions expressly required by the merger agreement or actions or omissions that are taken with the prior written consent of the other party, or as otherwise expressly permitted or contemplated by the merger agreement;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • any failure by Centre or Bank First to meet any internal or published industry analyst projections or forecasts or estimates of revenues or earnings for any period (it being understood and agreed that the facts and circumstances giving rise to such failure that are not otherwise excluded from the definition of material adverse effect may be taken into account in determining whether there has been a material adverse effect);

Centre has also agreed:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • to cause to be delivered to Bank First resignations of all the directors of Centre and its subsidiaries to be effective as of the effective time of the merger; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • to terminate certain contracts and pay any costs incurred in connection with such termination.

#### Regulatory Matters
Bank First and Centre agreed to use their respective commercially reasonable efforts to cause the registration statement to be declared effective by the SEC as promptly as reasonably practicable after filing. Bank First has also agreed to use its commercially reasonable efforts to obtain all necessary state securities law or "blue sky" permits and approvals required to carry out the transactions contemplated by the merger agreement.

------

[**TABLE OF CONTENTS**](#TOC)

Bank First and Centre and their respective subsidiaries have agreed to cooperate with each other and use their reasonable best efforts to prepare and file all necessary documentation, to effect all filings, to obtain as promptly as practicable all permits, consents, approvals and authorizations of all third parties and regulatory and governmental entities that are necessary to consummate the transactions contemplated by the merger agreement, and to comply with the terms and conditions of all such permits, consents, approvals and authorizations; *provided, however*, that nothing contained in the merger agreement will require Bank First or any of its subsidiaries or Centre or any of its subsidiaries to take any non-standard action, or commit to take any such action, or agree to any non-standard condition or restriction, in connection with obtaining the foregoing permits, consents, approvals and authorizations of any governmental authority that would reasonably be likely to have a material and adverse effect (measured on a scale relative to Centre) on the condition (financial or otherwise), results of operations, liquidity, assets or deposit liabilities, properties or business of Bank First, Centre, the surviving entity or the surviving bank, after giving effect to the merger (a "burdensome condition").

Bank First and Centre will furnish each other and each other's counsel with all information as may be necessary or advisable in connection with any application, petition or any other statement or application made by or on behalf of Bank First or Centre to any governmental authority in connection with the transactions contemplated by the merger agreement. Each party has the right to review and approve in advance all characterizations of the information relating to such party and any of its subsidiaries that appear in any filing with a governmental authority made in connection with the transactions contemplated by the merger agreement. In addition, Bank First and Centre agreed to provide to the other party for review a copy of each filing with a governmental authority made in connection with the transactions contemplated by the merger agreement prior to its filing.

#### Nasdaq Listing
Bank First has agreed to use its commercially reasonable efforts to cause the shares of its common stock to be issued in connection with the merger to be approved for listing on the Nasdaq Capital Market, subject to official notice of issuance, prior to the effective time of the merger.

#### Employee Matters
Following the effective time of the merger, for a period ending on the earlier of (i) the six-month anniversary of the effective time of the merger or (ii) the last day that such covered employee (as defined below) is employed by Bank First or one of its affiliates, Bank First must maintain employee benefit plans for those persons who are full-time employees of Centre and its subsidiaries on the closing date of the merger and who become full-time employees of Bank First (referred to as "covered employees") that provide employee benefits which, in the aggregate, are substantially comparable to the employee benefits and cash-based compensation opportunities that are made available on a uniform and non-discriminatory basis to similarly situated employees of Bank First or its subsidiaries (except that no covered employee may participate in any closed or frozen plan of Bank First or its subsidiaries). Bank First will give the covered employees credit for their prior service with Centre and its subsidiaries for purposes of eligibility and vesting under any employee benefit plan maintained by Bank First in which covered employees may be eligible to participate.

With respect to any Bank First health, dental, vision or other welfare plan in which any covered employee is eligible to participate, for the plan year that includes the closing, if the covered employee is eligible to participate in such plans, Bank First or its applicable subsidiary must use its commercially reasonable efforts to cause any pre-existing condition limitations or eligibility waiting periods under such plan to be waived with respect to the covered employee and his or her covered dependents to the extent the condition was, or would have been, covered under the Centre benefit plan in which the covered employee participated immediately prior to the effective time of the merger.

Covered employees will be credited with an amount of paid time off equal to such covered employee's accrued but unused paid time off at First National Bank (referred to as "carryover PTO"), provided, that to the extent permitted by law, (i) Bank First may allocate the carryover PTO and between vacation leave and sick leave in its discretion, and (ii) carryover PTO shall be limited to 80 hours per year for hourly employees, and salaried employees will not be allowed any carryover PTO.

------

[**TABLE OF CONTENTS**](#TOC)

Employees of Centre or First National Bank who do not become employees of Bank First or Bank First, N.A. at the effective time of the merger (other than for cause, death, disability, normal retirement or voluntarily resignation) will be entitled to receive severance compensation based on the number of years of service and position held with Centre, with a minimum of five times the employee's weekly base pay and a maximum of 18 times the employees weekly base pay paid to any such employee, typically.

Bank First will establish a retention bonus pool, in an amount to be determined in the sole discretion of Bank First, to encourage certain Centre employees to remain employed with Bank First, thereby assisting Bank First with continuity planning following the announcement and consummation of the transactions contemplated by the merger agreement.

Prior to the effective time of the merger, Centre will effectuate the termination or discontinuation of certain benefits plans maintained by Centre, as requested by Bank First. Additionally, no later than 90 days prior to the effective time of the merger, Centre will furnish to Bank First its calculations, whether preliminary or final, regarding the applicability of Section 280G of the Internal Revenue Code. These calculations will pertain to any disqualified individual in connection with the transactions contemplated by the merger agreement, either individually or in combination with other events.

#### Indemnification and Directors' and Officers' Insurance
The merger agreement provides that, for a period of six years after the effective time of the merger, Bank First shall indemnify and hold harmless the present and former directors and officers of Centre and its subsidiaries against all costs or expenses (including reasonable attorneys' fees), judgments, fines, losses, claims, damages or other liabilities incurred in connection with any claim, action, suit, proceeding or investigation arising out of actions or omissions of such persons in the course of performing their duties for Centre or its subsidiaries occurring at or before the effective time of the merger (including the transactions contemplated by the merger agreement), to the same extent as such persons have the right to be indemnified pursuant to the organizational documents of Centre in effect as of the date of the merger agreement to the extent permitted by applicable law (provided, however, that Bank First does not have any obligation to provide indemnification for any excluded claims (as defined in the merger agreement)).

For a period of six years after the effective time of the merger, Bank First will provide directors' and officers' liability insurance that serves to reimburse the present and former officers and directors of Centre or its subsidiaries with respect to claims against them arising from facts or events occurring before the effective time of the merger (including the transactions contemplated by the merger agreement). The directors' and officers' liability insurance will contain at least the same coverage and amounts, and contain terms and conditions no less advantageous to the indemnified person as the coverage currently provided by Centre; *provided, however*, that: (i) if Bank First is unable to obtain or maintain the directors' and officers' liability insurance, then Bank First will use its commercially reasonable efforts to provide as much comparable insurance as is reasonably available, and (ii) officers and directors of Centre or its subsidiaries may be required to make application and provide customary representations and warranties to the carrier of the insurance. Bank First will not be required to expend for such tail insurance a premium amount in excess of an amount equal to 100% of the annual premiums paid by Centre for director and officer insurance in effect as of the date of the merger agreement.

Bank First has agreed that if it, or any of its successors and assigns, consolidates with or merges with any other corporation or entity where it is not the continuing or surviving corporation, or transfers all or substantially all of its property or assets, it will make proper provision so that the successors and assigns of Bank First and its subsidiaries will assume the obligations of indemnification under the merger agreement.

------

[**TABLE OF CONTENTS**](#TOC)

#### No Solicitation
Centre has agreed that, from the date of the merger agreement it will not, and will cause its subsidiaries and each of their respective officers, directors and employees not to, and will not authorize or permit its investment bankers, financial advisors, attorneys, accountants, consultants, affiliates or other agents of Centre or any of its subsidiaries to, directly or indirectly, (i) initiate, solicit, induce or knowingly encourage, or take any action to facilitate the making of, any inquiry, offer or proposal which constitutes, or could reasonably be expected to lead to, an acquisition proposal; (ii) participate in any discussions or negotiations regarding any acquisition proposal or furnish, or otherwise afford access, to any person (other than Bank First) any information or data with respect to Centre or any of its subsidiaries or otherwise relating to an acquisition proposal; (iii) release any person from, waive any provisions of, or fail to enforce any confidentiality agreement or standstill agreement to which Centre is a party; or (iv) enter into any agreement, confidentiality agreement, agreement in principle or letter of intent with respect to any acquisition proposal or approve or resolve to approve any acquisition proposal or any agreement, agreement in principle or letter of intent relating to an acquisition proposal.

For purposes of the merger agreement, an "acquisition transaction" means (A) any transaction or series of transactions involving any merger, consolidation, recapitalization, share exchange, liquidation, dissolution or similar transaction involving Centre or any of its subsidiaries; (B) any transaction pursuant to which any third party or group acquires or would acquire (whether through sale, lease or other disposition), directly or indirectly, the assets of Centre or any of its subsidiaries constituting, in the aggregate, 20% or more of the fair value of the consolidated assets of Centre; (C) any issuance, sale or other disposition of (including by way of merger, consolidation, share exchange or any similar transaction) securities (or options, rights or warrants to purchase or securities convertible into, such securities) representing 20% or more of the votes attached to the outstanding securities of Centre or any of its subsidiaries; (D) any tender offer or exchange offer that, if consummated, would result in any third party or group beneficially owning 20% or more of any class of equity securities of Centre or any of its subsidiaries; or (E) any transaction which is similar in form, substance or purpose to any of the foregoing transactions, or any combination of the foregoing.

However, at any time prior to the Centre special meeting, Centre may take any of the actions described in the first paragraph of this "— No Solicitation" section if, but only if (i) Centre receives a bona fide unsolicited acquisition proposal that did not result from a breach of the first paragraph of this section, and (ii) the Centre board of directors reasonably determines in good faith, after consultation with and having considered the advice of its outside financial advisor and outside legal counsel, that (A) such acquisition proposal constitutes or is reasonably likely to lead to a superior proposal and (B) the failure to take such action would cause it to violate its fiduciary duties to Centre's shareholders under applicable law, (iii) Centre has provided Bank First with at least three business days prior notice of such determination, and (iv) prior to furnishing or affording access to any information or data with respect to Centre or any of its subsidiaries or otherwise relating to an acquisition proposal, Centre receives from such person a confidentiality agreement with terms no less favorable to Centre than those contained in the confidentiality agreement with Bank First. Centre must promptly provide to Bank First any non-public information regarding Centre or any of its subsidiaries provided to any other person which was not previously provided to Bank First, and such additional information must be provided no later than the date of provision of such information to such other party.

A "superior proposal" means a bona fide, unsolicited acquisition proposal (i) that if consummated would result in a third party (or in the case of a direct merger between such third party and Centre or any of its subsidiaries, the shareholders of such third party) acquiring, directly or indirectly, more than 50% of the outstanding Centre common stock or more than 50% of the assets of Centre and its subsidiaries (measured as a percentage of the fair value of the consolidated assets of Centre), taken as a whole, for consideration consisting of cash and/or securities and (ii) that the board of directors of Centre reasonably determines in good faith, after consultation with its outside financial advisor and outside legal counsel, (a) is reasonably capable of being completed, taking into account all financial, legal, regulatory and other aspects of such proposal, including all conditions contained therein and the person making such acquisition proposal, and (b) taking into account any changes to the merger agreement proposed by Bank First in response to such acquisition proposal, and all financial, legal, regulatory and other aspects of such proposal, including all conditions contained therein and the person making such acquisition proposal, such proposal is more favorable to the shareholders of Centre from a financial point of view than the merger.

------

[**TABLE OF CONTENTS**](#TOC)

Centre must promptly (and in any event within 24 hours) notify Bank First in writing if any proposals or offers are received by, any information is requested from, or any negotiations or discussions are sought to be initiated or continued with, Centre or its representatives, in each case in connection with any acquisition proposal, and such notice must indicate the name of the person initiating such discussions or negotiations or making such proposal, offer or information request and the material terms and conditions of any proposals or offers (and, in the case of written materials relating to such proposal, offer, information request, negotiations or discussion, providing copies of such materials (including e-mails or other electronic communications), except to the extent that such materials constitute confidential information of the party making such offer or proposal under an effective confidentiality agreement). Centre has agreed that it will keep Bank First informed, on a reasonably current basis, of the status and terms of any such proposal, offer, information request, negotiations or discussions (including any amendments or modifications to such proposal, offer or request).

Except as provided below, neither the board of directors of Centre nor any committee thereof shall (i) withdraw, qualify, amend or modify, or propose to withdraw, qualify, amend or modify, in a manner adverse to Bank First in connection with the transactions contemplated by the merger agreement (including the merger), the Centre recommendation, fail to reaffirm the Centre recommendation within three business days following a request by Bank First, or make any statement, filing or release, in connection with the Centre special meeting or otherwise, inconsistent with the Centre recommendation (it being understood that taking a neutral position or no position with respect to an acquisition proposal will be considered an adverse modification of the Centre recommendation); (ii) approve or recommend, or propose to approve or recommend, any acquisition proposal; or (iii) enter into (or cause Centre or any of its subsidiaries to enter into) any letter of intent, agreement in principle, acquisition agreement or other agreement (a) related to any acquisition transaction (other than a confidentiality agreement entered into in accordance with the foregoing) or (b) requiring Centre to abandon, terminate or fail to consummate the merger or any other transaction contemplated by the merger agreement.

Notwithstanding the foregoing, prior to the date of the Centre special meeting, the board of directors of Centre may withdraw, qualify, amend or modify the Centre recommendation ("Centre subsequent determination"), or terminate the merger agreement in order to concurrently enter into an agreement with respect to a superior proposal, after the fifth business day following Bank First's receipt of a notice (the "notice of superior proposal") from Centre advising Bank First that the board of directors of Centre has decided, in good faith after consultation with its outside legal counsel and financial advisor, that a bona fide unsolicited written acquisition proposal that it received (that did not result from a breach of the merger agreement) constitutes a superior proposal if, but only if, (i) the board of directors of Centre has determined in good faith, after consultation with and having considered the advice of outside legal counsel and its financial advisor, that the failure to take such action would cause it to violate its fiduciary duties to Centre's shareholders under applicable law, (ii) during the five business day period after receipt of the notice of superior proposal by Bank First (the "notice period"), Centre and the board of directors of Centre shall have cooperated and negotiated in good faith with Bank First to make such adjustments, modifications or amendments to the terms and conditions of the merger agreement as would enable Centre to proceed with the Centre recommendation in favor of the merger with Bank First without a Centre subsequent determination; *provided, however*, that Bank First does not have any obligation to propose any adjustments, modifications or amendments to the terms and conditions of the merger agreement, and (iii) at the end of the notice period, after taking into account any such adjusted, modified or amended terms as may have been proposed by Bank First since its receipt of such notice of superior proposal, the board of directors of Centre has again in good faith made the determination that such acquisition proposal constitutes a superior proposal. In the event of any material revisions to the superior proposal, Centre is required to deliver a new notice of superior proposal to Bank First and again comply with the foregoing requirements, except that the notice period will be reduced to three business days.

#### Termination of the Merger Agreement

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • upon the mutual written agreement of the parties if the board of directors of each so determines by a vote of a majority of the members of the entire board;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • by either party if any requisite regulatory approval is denied by a final, nonappealable action of any governmental authority or an application therefor shall have been permanently withdrawn at the request of a governmental authority unless the failure to obtain any requisite regulatory approval is due to the failure of the party seeking to terminate the merger agreement to perform or observe the obligations, covenants and agreements of such party set forth in the merger agreement;

#### MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS OF CENTRE
 *The following is a discussion of the financial condition of Centre as of June 30, 2025, December 31, 2024, and December 31, 2023, and its results of operations for each of the six months ended June 30, 2025, and 2024, as well as the two years ended December 31, 2024, and 2023. The following discussion and analysis should be read in conjunction with the sections of this proxy statement/prospectus entitled "Special Cautionary Note regarding Forward-Looking Statements," "Risk Factors," and Centre's consolidated financial statements and the accompanying notes included elsewhere in this proxy statement/prospectus.* 

Centre is a financial holding company providing community banking through its wholly-owned subsidiary, First National Bank, headquartered in Beloit, Wisconsin. First National Bank grants commercial, residential and consumer loans, accepts deposits and provides trust services to customers primarily in southern Wisconsin and northern Illinois. First National Bank is subject to competition from other financial institutions and nonfinancial institutions providing financial products. Additionally, Centre and First National Bank are subject to the regulations of certain regulatory agencies and undergo periodic examination by those regulatory agencies.

As of June 30, 2025, Centre had total consolidated assets of $1.55 billion, total net loans of $982.9 million, total deposits of $1.29 billion and total shareholders' equity of $112.6 million.

Management's discussion and analysis is presented to assist the reader in understanding and evaluating the financial condition and results of operations of Centre. The analysis focuses on the consolidated financial statements, footnotes, and other financial data presented. The discussion highlights material changes from prior reporting periods and any identifiable trends which may affect Centre. Amounts have been rounded for presentation purposes. This discussion and analysis should be read in conjunction with the "Audited Consolidated Financial Statements of Centre 1 Bancorp, Inc." beginning on page [F](#tADRS)-[2](#tADRS) and the "Unaudited Consolidated Financial Statements of Centre 1 Bancorp, Inc." beginning on page [F](#tf1CBIS1)-[43.](#tf1CBIS1)

 *Critical Accounting Policies* 

The accounting and reporting policies of Centre conform to GAAP in the United States and general practices within the financial institution industry. To prepare financial statements in conformity with GAAP, management makes estimates, assumptions and judgments based on available information that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. These estimates, assumptions and judgments are based on information available as of the date of the financial statements and, as this information changes, actual results could differ from the estimates, assumptions and judgments reflected in the financial statements. Centre uses peer group historical loss factors as one factor in determining the inherent loss that may be present in its loan portfolio; however, actual losses could differ significantly from the peer group historical factors that are used. In addition, GAAP itself may change from one previously acceptable method to another method. Management has identified the allowance for credit losses as an accounting policy critical in understanding Centre's financial statements.

Our significant accounting policies are presented in Note 1 of our audited consolidated financial statements included with this proxy statement/prospectus, beginning on page [F](#NTCF)-[12](#NTCF). These policies, along with the disclosures presented in the other financial statement notes and in this discussion, provide information on how significant assets and liabilities are valued in the financial statements and how those values are determined. Recent accounting pronouncements and standards that have impacted or could potentially affect us are also discussed in Note 1 of our audited consolidated financial statements included with this proxy statement/prospectus.

***Allowance for Credit Losses —*** The allowance for credit losses is established as losses are estimated to have occurred through a provision for credit losses charged to earnings. Credit losses are charged against the allowance for credit losses when management believes a loan balance is confirmed to be uncollectible. Subsequent recoveries, if any, are credited to the allowance for credit losses.

The allowance for credit losses is adequate to cover probable credit losses relating to specifically identified loans, as well as probable credit losses inherent in the balance of the loan portfolio. The allowance

------

[**TABLE OF CONTENTS**](#TOC2)

for credit losses is based on past events and current economic conditions and does not include the effects of expected losses on specific loans or groups of loans that are related to future events or expected changes in economic conditions. While management uses the best information available to make its evaluation, future adjustments to the allowance for credit losses may be necessary if there are significant changes in economic conditions. The allowance is comprised of both a specific reserve component and a general reserve component. Centre has elected to exclude accrued interest receivable from its calculation of the allowance for credit losses.

The specific reserve relates to all individually evaluated loans for which the allowance for credit losses is estimated on a loan-by-loan basis. A loan is considered an individually evaluated loan when, based on current information and events, it is probable that First National Bank will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Impairment is measured on a loan-by-loan basis as the excess of amortized cost over the present value of expected future cash flows discounted at the loan's effective interest rate, the loan's obtainable market price, or the fair value of the collateral if the loan is collateral dependent.

Centre qualitatively adjusts model results and peer group historical loss data for risk factors that are not considered within the modeling processes but are nonetheless relevant in assessing the expected credit losses within the loan pools, including current conditions and reasonable and supportable economic forecasts. These qualitative factors and other qualitative adjustments may increase or decrease Centre's estimate of expected credit losses by a calculated percentage or amount based upon the estimated level of risk. The various risks that may be considered in making qualitative adjustments include, among other things, the impact of environmental factors such as (i) changes in the nature, volume and terms of loans, (ii) changes in lending personnel, (iii) changes in the quality of the loan review function, (iv) changes in nature and volume of past-due, non-accrual and/or classified loans, (v) changes in concentration of credit risk, (vi) changes in economic and industry conditions, (vii) changes in legal and regulatory requirements, (viii) unemployment and inflation statistics, and (ix) changes in underlying collateral values.

A discounted cash flow method is used for each loan in a pool and the results are aggregated at the pool level. The analysis produces expected cash flows for each instrument in the pool by pairing loan-level term information, e.g., maturity date, payment amount, interest rate, and etc., with top-down pool assumptions, e.g., default rates and prepayment speeds.

In determining the proper level of the allowance for credit losses, Centre determined that the loss experience provides the best basis for the assessment of expected credit losses. Centre therefore used historical credit loss experience by each loan segment over an economic cycle. For most of the segment models for collectively evaluated loans, Centre incorporated two or more macroeconomic drivers using a statistical regression modeling methodology.

In addition, various regulatory agencies periodically review the allowance for credit losses. These agencies may require Centre to make additions to the allowance for credit losses based on their judgments of collectability based on information available to them at the time of their examination.

#### Results of Operations — Comparison of Results between the Six Months Ended June 30, 2025 and the Six Months Ended June 30, 2024
***General.*** Net income increased $752,000, or 24.1%, to $3.9 million for the six months ended June 30, 2025, from $3.1 million for the six months ended June 30, 2024. Details of significant changes are discussed below.

***Net Interest Income.*** Net interest income increased $2.1 million, or 11.9%, to $19.4 million for the six months ended June 30, 2025, from $17.3 million for the six months ended June 30, 2024. Total average interest-earning assets increased to $1.42 billion for the six months ended June 30, 2025, from $1.41 billion for the six months ended June 30, 2024.

Centre's net interest margin increased 31 basis points to 2.66% for the six months ended June 30, 2025, from 2.35% for the six months ended June 30, 2024. The increase was driven primarily by the repricing of variable rate loans as well as the origination of new loans in a higher interest rate environment.

------

[**TABLE OF CONTENTS**](#TOC2)

***Interest Income.*** Total interest income increased $1.6 million, or 5.2%, to $32.1 million for the six months ended June 30, 2025, from $30.5 million for the six months ended June 30, 2024. This increase was driven by higher yields on loan originations during 2025. The yield on loans receivable increased 33 basis points to 5.57% for the six months ended June 30, 2025, from 5.24% for the six months ended June 30, 2024. The increase was driven primarily by the repricing of variable rate loans as well as the origination of new loans in a higher interest rate environment.

***Interest Expense.*** Interest expense decreased $470,000, or 3.6%, to $12.7 million for the six months ended June 30, 2025, from $13.2 million for the six months ended June 30, 2024. This decrease was a result of a shift in funding sources from higher rate FHLB advances to lower cost deposits. Deposits increased to 92% of all funding sources at June 30, 2025, from 85% of all funding sources at June 30, 2024.

***Provision for Credit Losses.*** Centre's provision for credit losses is a charge to income in order to bring its allowance for credit losses to a level deemed appropriate by management. The provision for credit losses was $50,000 for the six months ended June 30, 2025, and $224,000 for the six months ended June 30, 2024. The provision for credit losses for the six months ended June 30, 2025 and 2024 were related to management's estimation of the allowance for credit losses, as described above in the "*Allowance for Credit Losses"* section. Centre's credit quality metrics remained strong with minimal nonperforming assets and past due loans as of June 30, 2025.

***Noninterest Income.*** Centre's primary sources of noninterest income are service charges and fees on deposits accounts, debit card income and trust income, investment sales commissions, mortgage banking income and income from bank-owned life insurance. Noninterest income does not include loan origination fees, which are recognized over the life of the related loan as an adjustment to yield using the interest method. Noninterest income increased $319,000, or 3.4% to $9.8 million for the six months ended June 30, 2025, from $9.5 million for the six months ended June 30, 2024.

The following table is a comparison of the components of noninterest income for the six months ended June 30, 2025 and 2024:

---

| | | | | |
|:---|:---|:---|:---|:---|
| | **For the six months <br> ended June 30,**  | **For the six months <br> ended June 30,**  | **Change <br> ($)**  | **Change <br> (%)**  |
| **(Dollars in thousands)**  | **2025**  | **2024**  | **Change <br> ($)**  | **Change <br> (%)**  |
| Service charges and fees on deposit accounts  | $2623 | $2327 | $296 | 12.7% |
| Debit card income  | 1860 | 1873 | (13) | (0.7)% |
| Trust income  | 2977 | 2734 | 243 | 8.9% |
| Investment sales commissions  | 326 | 473 | (147) | (31.1)% |
| Mortgage banking income  | 761 | 834 | (73) | (8.8)% |
| Income from bank-owned life insurance  | 647 | 622 | 25 | 4.0% |

---

Notable variances for the noninterest income table above are as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Service charges and fees increased compared to the prior period due to First National Bank's migration of checking account products from basic checking to its ONE account that charges a monthly fee and provides various benefits to the account holder. This migration increased service charges and fees by approximately $50,000 per month.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Trust income increased compared to the prior period based on the value of the assets held in trust.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Investment sales commissions decreased compared to the prior period as a result of strong one-time commissions earned in the prior period.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Mortgage banking income decreased from the prior period as a result of holding more mortgage production in the current period, compared to selling mortgage production into the secondary markets as was done in the prior period.

***Noninterest Expense.*** Centre's primary components of noninterest expense are compensation and employee benefits, premises and occupancy costs, data processing and technology expense and professional

services. Noninterest expense increased $1.5 million, or 6.8% to $24.3 million for the six months ended June 30, 2025, from $22.8 million for the six months ended June 30, 2024.

The following table is a comparison of the components of noninterest expense for the six months ended June 30, 2025 and 2024:

---

| | | | | |
|:---|:---|:---|:---|:---|
| | **For the six months <br> ended June 30,**  | **For the six months <br> ended June 30,**  | **Change <br> ($)**  | **Change <br> (%)**  |
| **(Dollars in thousands)**  | **2025**  | **2024**  | **Change <br> ($)**  | **Change <br> (%)**  |
| Compensation and employee benefits  | $14172 | $13036 | $1136 | 8.0% |
| Premises and occupancy costs  | 2271 | 2304 | (33) | (1.4)% |
| Data processing and technology expense  | 2491 | 2287 | 204 | 8.9% |
| Professional services  | 1547 | 1340 | 207 | 15.4% |

---

Notable variances in the noninterest expense table above are as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Compensation and employee benefits increased primarily because of normal merit increases which occurred on January 1, 2025, as well as an increase in health benefit costs provided to employees.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Data processing increased due to contractual price increases in IT-related contracts based primarily on increases in CPI.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Professional services increased as legal, audit and tax services all increased compared to the prior period, due in part to increases in fees for internal and external audit services.

***Income Tax Expense.*** Income tax expense increased $258,000, or 39.0%, to $920,000 for six months ended June 30, 2025, from $662,000 for the six months ended June 30, 2024. This increase is due to an increase in the effective tax rate, which increased to 19.2% for the six months ended June 30, 2025, from 17.5% for the six months ended June 30, 2024, as well as an increase in pretax earnings, which increased by $1.0 million, or 26.7%, to $4.8 million for the six months ended June 30, 2025, from $3.8 million for the six months ended June 30 2024.

#### Results of Operations — Comparison of Results between the Year Ended December 31, 2024 and the Year Ended December 31, 2023
***General.*** Net income increased $3.8 million, or 162.5%, to $6.1 million for the year ended December 31, 2024, from $2.3 million for the year ended December 31, 2023. In 2023, Centre was significantly impacted by a change in Wisconsin state tax law causing Centre to record impairment on its deferred tax asset related to the unrealized losses on investment securities.

***Net Interest Income.*** Net interest income decreased $108,000, or 0.3%, to $35.5 million for the year ended December 31, 2024, from $35.6 million for the year ended December 31, 2023. Total average interest-earning assets increased to $1.42 billion for the year ended December 31, 2024 from $1.41 billion for the year ended December 31, 2023. Centre's net interest margin decreased two basis points to 2.40% for the year ended December 31, 2024, from 2.42% for the year ended December 31, 2023.

***Interest Income.*** Total interest income increased $5.7 million, or 10.1%, to $62.1 million for the year ended December 31, 2024, from $56.4 million for the year ended December 31, 2023. This increase was driven by higher yields on loan originations during 2024. The yield in loans receivable increased 47 basis points to 5.33% for the year ended December 31, 2024, from 4.86% for the year ended December 31, 2023.

***Interest Expense.*** Interest expense increased $5.8 million, or 27.9%, to $26.7 million for the year ended December 31, 2024, from $20.9 million for the year ended December 31, 2023. This increase was a result of an increase in the cost of interest-bearing deposits, which increased 54 basis points, to 2.06% for the year ended December 31, 2024, from 1.52% for the year ended December 31, 2023.

***Provision for Credit Losses.*** Provision for credit losses increased $1.3 million, to $1.3 million for the year ended December 31, 2024, compared to a recovery of credit losses of $83,000 for the year ended December 31, 2023. The provision from credit losses recorded in 2024 related primarily to one loan secured by commercial real estate. The allowance from credit losses was $13.1 million, or 1.33% of total loans, at December 31, 2024, compared to $11.9 million, or 1.23% of total loans, at December 31, 2023.

***Noninterest Income.*** Noninterest income increased $2.2 million, or 12.8% to $19.4 million for the year ended December 31, 2024, from $17.3 million for the year ended December 31, 2023.

| Income from bank-owned life insurance  | 1262 | 974 | 288 | 29.6% |

---

Notable variances for the noninterest income table above are as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Service fees on deposit accounts increased from the prior year due to First National Bank's migration of checking account products from basic checking to its ONE account that charges a monthly fee and provides various benefits to the account holder.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Trust income increased compared to the prior year based on the value of the assets held in trust.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Investment sales commissions increased due to customers opting to invest in certain fixed annuities in the current year.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Mortgage banking income increased as more 1-4 family residential mortgage loans were originated and sold into the secondary market.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Income from bank-owned life insurance increased as a result of higher crediting rates provided by the various insurance carriers.

***Noninterest Expense.*** Noninterest expense increased $65,000, or 0.1% to $46.1 million for the year ended December 31, 2024, from $46.1 million for the year ended December 31, 2023.

***Income Tax Expense.*** Income tax expense decreased $3.0 million, or 67.9%, to $1.5 million for the year ended December 31, 2024, from $4.5 million for the year ended December 31, 2023. The state of Wisconsin passed tax legislation during the third quarter of 2023 which exempted income produced by a significant portion of Centre's loans from taxation in Wisconsin. As a result of the lower anticipated future effective tax rate, Centre determined that a $3.4 million allowance was required to be made against its deferred tax asset, creating a one-time increase in tax expense for 2023.

#### Financial Condition
***Total Assets.*** Total assets decreased $31.7 million, or 2.0%, to $1.55 billion at June 30, 2025 from $1.58 billion at December 31, 2024. Total assets increased $4.3 million, or 0.3%, to $1.58 billion at December 31, 2024 from $1.57 billion at December 31, 2023. The changes in the various asset categories are discussed below.

***Cash and Cash Equivalents.*** Cash and cash equivalents decreased by $46.2 million, or 49.3%, to $47.4 million at June 30, 2025, from $93.6 million at December 31, 2024. This decrease was a result of the seasonal nature of Centre's municipal deposit customers. Cash and cash equivalents increased by $35.3 million, or 60.4%, to $93.6 million at December 31, 2024 from $58.3 million at December 31, 2023. This increase was a result of an increase in customer deposits from the prior year.

***Investment Securities.*** The carrying value of total investment securities increased $6.7 million, or 1.7%, to $404.5 million at June 30, 2025, from $397.8 million at December 31, 2024. The increase was primarily due to increases in the fair value of the available-for-sale investments. The carrying value of total investment securities decreased $48.0 million, or 10.8%, to $397.8 million at December 31, 2024 from $445.8 million at December 31, 2023. This decrease was primarily a result of investment maturities with the cash received being redeployed into the loan portfolio.

The following tables show the fair value and weighted average yield of available for sale securities as of June 30, 2025, December 31, 2024 and December 31, 2023 according to contractual maturity. Actual maturities may differ from contractual maturities of residential mortgage-backed securities because the mortgages underlying the securities may be called or prepaid with or without penalty.

The weighted average yield is calculated using the purchased yield and amortized cost at each period presented. No adjustments have been made to adjust any yield to a taxable-equivalent yield.

***Deposits.*** First National Bank's main source of funding is comprised of deposits received from individuals, governmental entities and businesses located within First National Bank's service area. Deposit accounts include demand deposits, savings, money market and certificates of deposit.

Deposits decreased $24.4 million, or 1.9%, to $1.29 billion at June 30, 2025, from $1.32 billion at December 31, 2024. This decrease, as mentioned above, was primarily due to the seasonal nature of municipal deposit customers. Deposits increased $54.7 million, or 4.3%, to $1.32 billion at December 31, 2024 from $1.26 billion at December 31, 2023. This increase was a result of Centre's customer-focused approach to deposit gathering and the deepening of existing relationships as part of Centre's operating strategy.

As of June 30, 2025, December 31, 2024, and December 31, 2023, approximately $283.9 million, $334.2 million, and $419.1 million, respectively, of our total deposit portfolio was uninsured. The uninsured amounts are estimates based on the methodologies and assumptions used for Centre's regulatory reporting requirements. The aggregate amount of time deposits, each with a minimum denomination over $250,000 as of June 30, 2025, December 31, 2024 and December 31, 2023 was $58.4 million, $61.3 million and $33.7 million, respectively. As of June 30, 2025, brokered deposits totaled $15.0 million.

***Borrowings and Securities sold under repurchase agreements.*** Borrowings decreased $16.1 million, or 12.8%, to $110.1 million at June 30, 2025, from $126.2 million at December 31, 2024. Securities sold under repurchase agreements decreased $5.7 million, or 72.4%, to $2.2 million at June 30, 2025, from $7.9 million at December 31, 2024. Borrowings decreased $32.9 million, or 20.7%, to $126.2 million at December 31, 2024, from $159.1 million at December 31, 2023. Securities sold under repurchase agreements decreased $31.3 million, or 79.9%, to $7.9 million at December 31, 2024, from $39.2 million at December 31, 2023. The decreases in borrowing and securities sold under repurchase agreements were attributed to prudent management of Centre's cash levels using excess cash from investment maturities and deposit increases to repay these other higher cost funding sources.

***Stockholders' Equity.*** Total stockholders' equity increased $12.4 million, or 12.3%, to $112.6 million at June 30, 2025, from $100.2 million at December 31, 2024. This increase was attributed to net income during the six-month period as well as an increase in the fair value of available-for-sale investments and related other comprehensive income adjustment within equity. Total stockholders' equity increased $5.6 million, or 6.0%, to $100.2 million at December 31, 2024 from $94.6 million at December 31, 2023. Net income was the primary source of this increase.

***Loans.*** Net loans increased by $10.9 million, or 1.1%, to $982.9 million at June 30, 2025 from $972.0 million at December 31, 2024. This increase was due to a continued effort to expand Centre's customer base, while protecting its current customers from other financial institutions. Net loans increased by $18.6 million, or 2.0%, to $972.0 million at December 31, 2024 from $953.4 million at December 31, 2023. This increase was due to new loan customers and the deepening of relationships with existing customers. Commercial loans increased $16.9 million during the year ended December 31, 2024.

 *<u>Loan Portfolio</u>* 

In order to manage the diversification of the loan portfolio, Centre segments loans into classes. The real estate loan segment is sub-segmented into commercial real estate loans and 1-4 family residential loans.

Centre's commercial loan segment encompasses loans extended to businesses for various purposes, including working capital, equipment financing, other real property acquisition and development, and other business-related needs. These include commercial and industrial, agricultural production, and municipal loans. Commercial loans are loans primarily underwritten based on the cash flows of the business operations of the borrower and secured by assets being financed such as accounts receivable, inventory, and equipment. Commercial loans often are dependent on the profitable operations of the borrower. In the case of loans secured by accounts receivable, the availability of funds for the repayment of these loans may be substantially dependent on the ability of the borrower to collect amounts due from its customers. The cash flows of borrowers may not be as expected and the collateral securing these loans may fluctuate, increasing the risk associated with this loan segment. As a result of the additional complexities, variables, and risks, commercial loans typically require more thorough underwriting and servicing than other types of loans.

Centre makes commercial real estate mortgage loans, including construction, agricultural, and multifamily loans, which are primarily viewed as cash flow loans and secondarily as loans secured by real estate. The properties securing Centre's commercial real estate loans can be owner occupied or non-owner occupied. Concentrations within the various types of commercial properties are monitored by management in order to assess the risks in the portfolio. The repayment of these loans is largely dependent on the successful operation of the property securing the loan or the business conducted on the property securing the loan. Accordingly, repayment of these loans may be subject to adverse conditions in the real estate market or the economy to a greater extent than other types of loans. Centre seeks to minimize these risks in a variety of ways in connection with underwriting these loans, including giving careful consideration to the property's operating history, future operating projections, current and projected occupancy, location and physical condition.

Centre's 1-4 family residential loans include the origination of 1-4 family residential mortgage loans and home equity lines of credit collateralized by owner-occupied residential properties generally located in the market areas in which Centre has branch locations.

Centre's consumer loans are primarily comprised of construction loans and auto loans, other personal loans and credit card loans. The terms of these loans typically range from 1 to 15 years and vary based on the nature of collateral and size of the loan. Consumer loan collections are dependent on the borrower's continuing financial stability, and thus more likely to be adversely affected by job loss, illness or personal bankruptcy. Furthermore, the application of various federal and state laws may limit the amount which can be recovered on such loans. To monitor and manage consumer loan risk, policies and procedures are developed and modified, as deemed appropriate by Centre's management.

The information in the following table is based on the contractual maturities of individual loans, including loans that may be subject to renewal at their contractual maturity. Renewal of these loans is subject to review and credit approval, as well as modification of terms upon maturity. Actual repayments of loans may differ from the maturities reflected below because borrowers have the right to prepay obligations with or without prepayment penalties. Demand loans, loans having no stated repayment schedule and stated maturity dates, and overdraft loans were reported as being due in one year or less. The following table summarizes the loan maturity distribution by type and related interest rate characteristics as of the periods presented:

<u>Allowance for Credit Losses</u> 

The allowance for credit losses is recognized when losses are estimated to have occurred, through a provision for credit losses recorded in earnings. Credit losses are charged against the allowance for credit losses when management believes the uncollectability of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance for credit losses. The allowance for credit losses is adequate to cover probable credit losses relating to specifically identified loans, as well as probable credit losses inherent in the balance of the loan portfolio. The allowance for credit losses is based on past events and current economic conditions and does not include the effects of expected losses on specific loans or groups of loans that are related to future events or expected changes in economic conditions. While management uses the best information available to make its evaluation, future adjustments to the allowance for credit losses may be necessary if there are significant changes in economic conditions. The allowance is comprised of both a specific reserve component and a general reserve component. Centre has elected to exclude accrued interest receivable from its calculation of the allowance for credit losses.

The specific reserve relates to all individually evaluated loans for which the allowance for credit losses is estimated on a loan-by-loan basis. A loan is considered an individually evaluated loan when, based on current information and events, it is probable that First National Bank will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Impairment is measured on a loan-by-loan basis as the excess of amortized cost over the present value of expected future cash flows discounted at the loan's effective interest rate, the loan's obtainable market price, or the fair value of the collateral if the loan is collateral dependent.

Centre qualitatively adjusts model results for risk factors that are not considered within the modeling processes but are nonetheless relevant in assessing the expected credit losses within the loan pools. These qualitative factors and other qualitative adjustments may increase or decrease Centre's estimate of expected credit losses by a calculated percentage or amount based upon the estimated level of risk. The various risks that may be considered in making qualitative adjustments include, among other things, the impact of environmental factors such as (i) changes in the nature, volume and terms of loans, (ii) changes in lending personnel, (iii) changes in the quality of the loan review function, (iv) changes in nature and volume of past-due, non-accrual and/or classified loans, (v) changes in concentration of credit risk, (vi) changes in economic and industry conditions, (vii) changes in legal and regulatory requirements, (viii) unemployment and inflation statistics, and (ix) changes in underlying collateral values.

A discounted cash flow method is used for each loan in a pool and the results are aggregated at the pool level. The analysis produces expected cash flows for each instrument in the pool by pairing loan-level term information, e.g., maturity date, payment amount, interest rate, etc., with top-down pool assumptions, for example default rates and prepayment speeds.

In determining the proper level of the allowance for credit losses, Centre determined that the loss experience provides the best basis for the assessment of expected credit losses. Centre therefore used historical credit loss experience by each loan segment over an economic cycle. For most of the segment models for collectively evaluated loans, Centre incorporated two or more macroeconomic drivers using a statistical regression modeling methodology.

In addition, various regulatory agencies periodically review the allowance for credit losses. These agencies may require Centre to make additions to the allowance for credit losses based on their judgments of collectability based on information available to them at the time of their examination.

The allowance for credit losses was $12.0 million, or 1.21% of total loans at June 30, 2025. The allowance for credit losses was $13.1 million, or 1.33% of total loans, at December 31, 2024, and $11.9 million, or 1.23% of total loans, at December 31, 2023.

The following table presents, as of and for the periods indicated, an analysis of the allowance for credit losses and other related data:

Centre had the ability to borrow funds from the FHLB in the amount of up to $210.3 million as of June 30, 2025, up to $148.2 million as of December 31, 2024, and up to $111.6 million as of December 31, 2023. Funds borrowed from the FHLB are collateralized by a lien on certain of Centre's available for sale securities and loans. In addition to borrowing ability with the FHLB, First National Bank had Fed Fund lines of credit of $75.0 million with four correspondent lenders as of June 30, 2025, December 31, 2024 and December 31, 2023.

In May 2025, Centre renewed a $20.0 million note payable with Bankers' Bank for an additional 12 months. There was no amount outstanding as of June 30, 2025, December 31, 2024, and December 31, 2023. The interest rate on the note is variable based on the Wall Street Journal Prime Rate (the "Index"), calculated as 50 basis points under the Index with a floor of 3.25%. At June 30, 2025 and December 31, 2024, respectively, the interest rate on the note was 7.00% and 8.00%, respectively. In June 2022, Centre took out a $6.0 million note payable with Bankers' Bank. There was $2.6 million, $3.2 million and $4.3 million outstanding as of June 30, 2025, December 31, 2024, and December 31, 2023, respectively. Interest on the note is fixed at 4.35%.

In January 2025, Centre entered into three subordinated term loans, maturing in 2035, with related purchasers. Interest on the loans is fixed at 6.75%. As of June 30, 2025 there was $4.5 million outstanding of the subordinated term loans.

The trust preferred debentures of $8.0 million mature in 2039 and were not redeemable, except under limited circumstances, until January 29, 2015 at par. The adjustable rate was 8% until January 29, 2015 and thereafter resets every three months at the three-month CME Term SOFR rate plus 2.20%. At June 30, 2025, December 31, 2024, and December 31, 2023, the interest rate on the adjustable, long-term debt was 6.73%, 7.71%, and 7.84%, respectively.

 *Capital* 

First National Bank desires to maintain a strong capital base to support current operations. As of June 30, 2025, First National Bank's total risk based capital and Tier 1 leverage ratios were 12.71% and 8.50%, respectively. These ratios are in excess of required regulatory minimums to be considered "well capitalized."

------

[**TABLE OF CONTENTS**](#TOC2)

First National Bank is subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory, and possible additional discretionary actions by regulators that, if undertaken, could have a direct material effect on Centre's consolidated financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, First National Bank must meet specific capital guidelines that involve quantitative measures of their assets, liabilities, and certain off-balance sheet items as calculated under regulatory accounting practices. First National Bank's capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors.

Quantitative measures established by regulation to ensure capital adequacy require First National Bank to maintain minimum thresholds for Common Equity Tier 1, or CET 1, total, and Tier 1 capital to risk-weighted assets, and Tier 1 capital to adjusted total assets, or Tier 1 leverage ratio. Tier 1 capital of First National Bank consists of common shareholders equity, excluding the unrealized gain or loss on securities available-for-sale, less certain intangible assets (if applicable), while CET 1 is comprised of Tier 1 capital, adjusted for certain regulatory deductions and limitations. Tier 2 capital consists of the allowance for loan losses subject to certain limitations. Total capital for purposes of computing the capital ratios consists of the sum of Tier 1 and Tier 2 capital. The new rule requires banks to hold CET 1 capital in excess of minimum risk-based capital ratios by at least 2.5% to avoid limits on capital distributions and certain discretionary bonus payments to executive officers. Management believes that First National Bank meets all capital adequacy requirements to which it is subject. First National Bank's actual capital amounts and ratios and minimum regulatory amounts and ratios established by regulations are set forth below:

Centre makes contractual commitments to extend credit in the ordinary course of its business activities. These commitments are legally binding agreements to lend money to customers of Centre at predetermined interest rates for a specified period of time. At June 30, 2025, December 31, 2024, and December 31, 2023, unfunded commitments to extend credit were $206.0 million, $224.1 million, and $247.8 million, respectively.

------

[**TABLE OF CONTENTS**](#TOC2)

In addition to commitments to extend credit, Centre also issues standby letters of credit that are assurances to a third party that it will not suffer a loss if Centre's customer fails to meet its contractual obligation to the third party. Standby letters of credit totaled approximately $6.6 million, $7.2 million, and $7.0 million at June 30, 2025, December 31, 2024, and December 31, 2023, respectively. Past experience indicates that many of these standby letters of credit will expire unused. However, through its various sources of liquidity discussed above, Centre believes that it will have the necessary resources to meet these obligations should the need arise.

 *Liquidity* 

Liquidity is the ability to meet present and future financial obligations through either the sale or maturity of existing assets or the acquisition of additional funds through liability management. Liquid assets include cash, interest-bearing deposits with banks, investments and loans maturing within one year. First National Bank's ability to obtain deposits and purchase funds at favorable rates determines its liquidity exposure. As a result of First National Bank's management of liquid assets and the ability to generate liquidity through liability funding, management believes that First National Bank maintains overall liquidity sufficient to satisfy its depositors' requirements and meet its customers' credit needs.

First National Bank is required to maintain a sufficient level of liquid assets, as determined by management and reviewed for adequacy by the OCC during its regular examinations. First National Bank frequently monitors its liquidity position primarily using the ratio of cash and cash equivalents and unpledged available for sale investments securities as a percentage of total assets (which we refer to as the "liquidity ratio"). First National Bank's liquidity ratio as of June 30, 2025 was 21.9%. First National Bank adjusts liquidity levels to meet funding needs for deposit outflows, payment of real estate taxes and insurance on mortgage loan escrow accounts, repayment of borrowings and loan fundings. As of June 30 2025, First National Bank had $210.3 million of additional borrowing capacity available with the FHLB of Chicago.

Additional sources of liquidity available to First National Bank include, but are not limited to, loan repayments, the ability to obtain deposits through the adjustment of interest rates and the purchasing of federal funds. To further meet its liquidity needs, First National Bank also maintains a lines of credit with its primary correspondent financial institutions, the Federal Reserve Bank of Chicago and the Federal Home Loan Bank of Chicago.

Centre is a legal entity, separate and distinct from First National Bank. A significant portion of the revenues of Centre result from dividends paid to it by First National Bank. There are various legal limitations applicable to the payment of dividends by First National Bank to Centre and to the payment of dividends by Centre to its shareholders. The payment of dividends by First National Bank or Centre may be limited by other factors, such as requirements to maintain capital above regulatory guidelines. First National Bank's regulatory agencies have the authority to prohibit First National Bank or Centre from engaging in an unsafe or unsound practice in conducting their business. The payment of dividends, depending on the financial condition of First National Bank, or Centre, could be deemed to constitute such an unsafe or unsound practice. In addition, under the current supervisory practices of the Federal Reserve, Centre should inform and consult with the Federal Reserve reasonably in advance of declaring or paying a dividend that exceeds earnings for the period for which the dividend is being paid or that could result in a material adverse change to Centre's capital structure.

Transfers of funds from First National Bank to Centre in the form of loans, advances, and cash dividends are restricted by federal and state regulatory authorities. At June 30, 2025, the aggregate amount of unrestricted funds which could be transferred from First National Bank to Centre, without prior regulatory approval, totaled $329.0 million. The amount of unrestricted funds is generally determined by subtracting the total dividend payments of First National Bank from First National Bank's net income for that year, combined with First National Bank's retained net income for the preceding two years.

For the six months ended June 30, 2025, and the years ended December 31, 2024 and 2023, the aforementioned restrictions on First National Bank's ability to transfer funds to Centre has not had and is not reasonably likely to have in the future, an impact on the ability of Centre to meet its cash obligations. Centre does not anticipate any material cash requirements outside of the ordinary course of business, other than those related to the merger.

<u>Rate/Volume Analysis of Net Interest Income</u> 

As discussed under the headings "*Net Interest Income*" above, Centre's net income is largely dependent on net interest income. The table below calculates the relative impact on net interest income caused by changes in the average balances (volume) of interest sensitive assets and liabilities and the impact caused by changes in interest rates earned or paid. Each table compares two periods as indicated below. The effect of a change in average balance has been determined by applying the average rate in the earlier year to the change in average balance in the later year, as compared with the earlier year. The effect of a change in the average rate has been determined by applying the average balance in the earlier year to the change in the average rate in the later year, as compared with the earlier year.

#### Quantitative and Qualitative Disclosures About Market Risk
In an effort to assess interest rate risk and market risk, Centre utilizes a simulation model to determine the effect of immediate incremental increases and decreases in interest rates on net interest income, the market value of equity and asset and liability duration. Certain assumptions are made regarding loan prepayments and decay rates of savings and interest-bearing demand accounts. Because it is difficult to accurately project the market reaction of depositors and borrowers, the effect of actual changes in interest rates on these assumptions may differ from simulated results. The following table illustrates the simulated impact of 100 bps, 200 bps or 300 bps upward and downward movement in interest rates on net interest income, economic value of equity and asset and liability durations at June 30, 2025.

#### DESCRIPTION OF CAPITAL STOCK OF BANK FIRST
As a result of the merger, Centre shareholders who receive shares of Bank First common stock in the merger will become shareholders of Bank First. Your rights as shareholders of Bank First will be governed by Wisconsin law and the Bank First Articles and Bank First Bylaws. The following briefly summarizes the material terms of Bank First common stock. We urge you to read the applicable provisions of the WBCL, the Bank First Articles and the Bank First Bylaws and federal laws governing bank holding companies carefully and in their entirety. Copies of Bank First's governing documents have been filed with the SEC. To obtain copies of these documents, see "Where You Can Find More Information." Bank First common stock is listed on the Nasdaq Capital Market under the symbol "BFC."

#### Common Stock
*Authorized.* Bank First has 20,000,000 shares of authorized common stock, $0.01 par value, of which 9,857,225 were outstanding as of September 22, 2025.

*Voting Rights; No Cumulative Voting.* Each share of common stock entitles the holder to one vote on all matters submitted to a vote of common shareholders, including the election of directors; provided, however, any person that beneficially owns, directly or indirectly, in excess of 20% of the voting power in the election of directors shall be limited to 10% of the full voting power of those shares. There is no cumulative voting in the election of directors. All elections of directors are determined by a plurality of the votes cast, and except as otherwise required by the Bank First Articles or by applicable Wisconsin law, all other matters are approved if the votes cast within the voting group favoring an action exceed the votes cast opposing such action at a properly called meeting of shareholders.

*Board of Directors.* Under the Bank First Bylaws and Bank First Articles, the number of directors shall be fixed from time to time exclusively by the board of directors pursuant to a resolution adopted by the board of directors, but in no event shall the number of directors be less than six nor more than fifteen. Currently, there are ten directors. The board of directors is divided into three classes so that each director serves for a term expiring at the third succeeding annual meeting of shareholders after their election with each director to hold office until his or her successor is duly elected and qualified. Directors are elected by a plurality of the votes cast at Bank First's annual meeting by the holders of shares present or represented by proxy and entitled to vote on the election of directors.

*Dividends; Liquidation; Preemptive Rights*. Holders of shares of Bank First common stock are entitled to receive dividends only when, as and if approved by the Bank First board of directors from funds legally available for the payment of dividends. Bank First's ability to pay dividends will be dependent on Bank First's earnings and financial conditions and subject to certain restrictions imposed by state and federal laws. Bank First shareholders are entitled to share ratably in Bank First's assets legally available for distribution to such shareholders in the event of Bank First's liquidation, dissolution or winding up, voluntarily or involuntarily, after payment of, or adequate provision for, all of Bank First's known debts and liabilities. These rights are subject to the preferential rights of any series of Bank First's preferred stock that may then be outstanding. Holders of shares of Bank First common stock have no preference, conversion, exchange, sinking fund or redemption rights and have no preemptive rights to subscribe for any of Bank First's securities. All outstanding shares of Bank First common stock are validly issued, fully paid and nonassessable.

Bank First is a legal entity separate and distinct from Bank First, N.A. There are various restrictions that limit the ability of Bank First, N.A. to finance, pay dividends or otherwise supply funds to Bank First or other affiliates. In addition, subsidiary banks of holding companies are subject to certain restrictions under Sections 23A and 23B of the Federal Reserve Act on any extension of credit to the bank holding company or any of its subsidiaries, on investments in the stock or other securities thereof and on the taking of such stock or securities as collateral for loans to any borrower. Further, a bank holding company and its subsidiaries are prohibited from engaging in certain tie-in arrangements in connection with extensions of credit, leases or sales of property, or furnishing of services.

[**TABLE OF CONTENTS**](#TOC2)

The principal sources of funds to Bank First to pay dividends are the dividends received from Bank First, N.A. Consequently, dividends are dependent upon Bank First, N.A.'s earnings, capital needs, regulatory policies, as well as statutory and regulatory limitations. Federal and state banking laws and regulations restrict the amount of dividends and loans a bank may make to its parent company. Approval by Bank First, N.A.'s regulators is required if the total of all dividends declared in any calendar year exceed the total of its net income for that year combined with its retained net income of the preceding two years.

Under certain conditions, dividends paid to Bank First by Bank First, N.A. are subject to approval by the OCC. A national bank may not pay dividends from its capital. All dividends must be paid out of undivided profits then on hand, after deducting expenses, including reserves for losses and bad debts. In addition, a national bank is prohibited from declaring a dividend on its shares of common stock until its surplus equals its stated capital, unless the bank has transferred to surplus no less than one-tenth of its net profits of the preceding two consecutive half-year periods (in the case of an annual dividend). The approval of the OCC is required if the total of all dividends declared by a national bank in any calendar year exceeds the total of its net profits for that year combined with its retained net profits for the preceding two years, less any required transfers to surplus. In addition, under the Federal Deposit Insurance Corporation Improvement Act, banks may not pay a dividend if, after paying the dividend, the bank would be undercapitalized.

*Preemptive Rights; Liquidation.* Bank First common stock does not carry any preemptive rights enabling a holder to subscribe for or receive shares of Bank First common stock. In the event of liquidation, holders of Bank First common stock are entitled to share in the distribution of assets remaining after payment of debts and expenses and after required payments to holders of Bank First preferred stock, if any such shares are outstanding. There are no redemption or sinking fund provisions applicable to Bank First common stock.

#### Preferred Stock
Under the terms of the Bank First Articles, Bank First has authorized the issuance of up to 5,000,000 shares of serial preferred stock, $0.01 par value per share, any part or all of which shares may be established and designated from time to time by the Bank First board of directors by filing an amendment to the Bank First Articles, which is effective without shareholder action, in accordance with the appropriate provisions of the WBCL. Bank First Articles authorize Bank First's board of directors to establish one or more series of preferred stock, and to establish such preferences, limitations and relative rights as may be applicable to each series of preferred stock. The issuance of preferred stock and the determination of the terms of preferred stock by the board, while providing flexibility in connection with possible acquisitions and other corporate purposes, could, among other things, adversely affect the voting power of the holders of Bank First common stock. Bank First does not currently have any shares of preferred stock issued and outstanding.

#### Anti-Takeover Provisions
*General.* Bank First Articles and Bank First Bylaws, as well as WBCL, contain certain provisions designed to enhance the ability of Bank First's board of directors to deal with attempts to acquire control of Bank First. These provisions may be deemed to have an anti-takeover effect and may discourage takeover attempts which have not been approved by the board of directors (including takeovers which certain shareholders may deem to be in their best interest). This summary does not purport to be complete and is qualified in its entirety by reference to the laws and documents referenced. With respect to Bank First's charter documents, while such provisions might be deemed to have some "anti-takeover" effect, the principal effect of these provisions is to protect Bank First's shareholders generally and to provide Bank First's board and shareholders a reasonable opportunity to evaluate and respond to such unsolicited acquisition proposals.

*Voting Requirements; Business Combinations or Control Share Acquisition.* The Bank First Articles require the affirmative vote of the holders of at least 80% of the then-outstanding shares of capital stock entitled to vote on the matter to approve certain business combinations; *provided, however*, in the case where the business combination has been approved by a majority of the board of directors, then the business combination may be approved by an affirmative vote of the holders of the majority of the outstanding shares of Bank First. Bank First shareholder approval is required to approve the merger and transactions contemplated by the merger agreement.

[**TABLE OF CONTENTS**](#TOC2)

*Authorized but Unissued Stock.* The authorized but unissued shares of common stock and preferred stock will be available for future issuance without shareholder approval. These additional shares may be used for a variety of corporate purposes, including future private or public offerings to raise additional capital, corporate acquisitions, and employee benefit plans. The existence of authorized but unissued and unreserved shares of common stock and preferred stock may enable the board of directors to issue shares to persons friendly to current management, which could render more difficult or discourage any attempt to obtain control of us by means such as a proxy contest, tender offer, or merger, and thereby protect the continuity of Bank First's management.

*Number and Classification of Directors.* Bank First Articles and Bank First Bylaws provide that the number of directors shall be fixed from time to time exclusively by the board of directors pursuant to a resolution adopted by the board of directors, but in no event shall the number of directors be less than six nor more than fifteen. The board of directors is divided into three classes so that each director serves for a term expiring at the third succeeding annual meeting of shareholders after their election with each director to hold office until his or her successor is duly elected and qualified. The classification of directors, together with the provisions in the Bank First Articles and Bank First Bylaws described below that limit the ability of shareholders to remove directors and that permit the remaining directors to fill any vacancies on the board of directors, have the effect of making it more difficult for shareholders to change the composition of the board of directors. As a result, at least two annual meetings of shareholders may be required for the shareholders to change a majority of the directors, whether or not a change in the board of directors would be beneficial and whether or not a majority of shareholders believe that such a change would be desirable, and three meetings, rather than one, would be required to replace the entire board. Directors are elected by a plurality of the votes cast at Bank First's annual meeting by the holders of shares present or represented by proxy and entitled to vote on the election of directors. Plurality means that the individuals who receive the largest number of "FOR" votes will be elected as directors. If, at the annual meeting, a shareholder does not vote for a nominee or indicates "WITHHOLD" for any nominee on his, her or its proxy card, such vote will not count "FOR" the nominee.

*Amendment of the Articles of Incorporation or Bylaws.* The affirmative vote of the holders of at least 80% of the voting power of all of the then-outstanding shares of capital stock entitled to vote is required to amend or repeal certain provisions of the Bank First Articles, including those provisions regarding voting shares held in excess of the 20% limit described above, the election and removal of directors, business combinations, and indemnification of directors and officers. The Bank First Articles also provides that the board of directors may amend the Bank First Articles without shareholder approval pursuant to Section 180.1002 of the WBCL. Except as provided in Section 180.1002 of the WBCL, the Bank First Articles can only be amended by an affirmative vote of the holders of 66-2/3% of all outstanding shares of stock entitled to vote on such amendment.

The Bank First Bylaws may be amended, altered or repealed and new bylaws may be adopted by the Bank First board of directors with an affirmative vote of a majority of directors present at, or participating in, any meeting at which a quorum is present. Bylaws adopted by the shareholders cannot be amended or repealed by the board of directors if such bylaw so provides. The Bank First Bylaws provide that any action taken or authorized by the shareholders or by the board of directors, which would be inconsistent with the Bank First Bylaws then in effect but is taken or authorized by affirmative vote of not less than the number of shares or the number of directors required to amend the Bank First Bylaws so that the bylaws would be consistent with such action, shall be given the same effect as though the bylaws had been temporarily amended or suspended so far, but only so far, as is necessary to permit the specific action so taken or authorized.

#### COMPARISON OF SHAREHOLDERS' RIGHTS
If the merger is completed, shareholders of Centre will become shareholders of Bank First. The rights of Centre shareholders are currently governed by and subject to the laws of the State of Wisconsin, as amended, and the Centre Articles and Centre Bylaws. Upon completion of the merger, the rights of the former Centre shareholders who receive shares of Bank First common stock will be governed by the WBCL and the Bank First Articles and Bank First Bylaws, rather than the Centre Articles and Centre Bylaws.

The following is a summary of the material differences between the rights of holders of Bank First common stock and holders of Centre common stock, but it does not purport to be a complete description of those differences, the specific rights of such holders or the terms of the Bank First common stock subject to issuance in connection with the merger. The following summary is qualified in its entirety by reference to the relevant provisions of: (1) Wisconsin law; (2) the Bank First Articles; (3) the Centre Articles; (4) the Bank First Bylaws; and (5) the Centre Bylaws.

The identification of some of the differences in the rights of such holders as material is not intended to indicate that other differences that may be equally important do not exist. You are urged to read carefully the relevant provisions of Wisconsin law, as well as the governing corporate instruments of each of Bank First and Centre, copies of which are available, without charge, to any person, including any beneficial owner to whom this proxy statement/prospectus is delivered, by following the instructions listed under "Where You Can Find More Information."

#### ACCOUNTING TREATMENT
The accounting principles applicable to the merger as described in FASB ASC 805 provide transactions that represent business combinations are to be accounted for under the acquisition method. The acquisition method requires all of the following steps: (1) identifying the acquirer; (2) determining the acquisition date; (3) recognizing and measuring the identifiable assets acquired, the liabilities assumed, and any noncontrolling interest in the acquiree; and (4) recognizing and measuring goodwill or a gain from a bargain purchase.

The appropriate accounting treatment for the merger is as a business combination under the acquisition method. On the acquisition date, as defined by ASC 805, Bank First (the acquirer) will record at fair value the identifiable assets acquired and liabilities assumed, any noncontrolling interest, and goodwill (or a gain from a bargain purchase). The results of operations for the combined company will be reported prospectively subsequent to the acquisition date.

#### MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER
The following is a general discussion of the anticipated material U.S. federal income tax consequences of the merger to "U.S. holders" (as defined below) of Centre common stock that exchange their shares for the merger consideration. The following discussion is based upon the Code, the U.S. Treasury regulations promulgated thereunder, judicial and administrative authorities, rulings, and decisions, all as in effect on the date of this proxy statement/prospectus. These authorities may change, possibly with retroactive effect, and any such change could affect the accuracy of the statements and conclusions set forth in this discussion. This discussion does not address any tax consequences arising under the laws of any state, local or foreign jurisdiction, or under any U.S. federal laws other than those pertaining to the income tax.

Further, this discussion is for general information only and does not purport to consider all aspects of U.S. federal income taxation that might be relevant to U.S. holders in light of their particular circumstances and does not apply to U.S. holders subject to special treatment under the U.S. federal income tax laws, including, without limitation, dealers or brokers in securities, commodities or currencies, traders in securities that elect to apply a mark-to-market method of accounting, banks and certain other financial institutions, insurance companies, mutual funds, tax-exempt organizations and entities, including pension plans, individual retirement accounts and employee stock ownership plans, holders subject to the alternative minimum tax provisions of the Code, partnerships, S corporations or other pass-through entities or investors in such entities, regulated investment companies, real estate investment trusts, former citizens or residents of the United States, holders whose functional currency is not the U.S. dollar, or holders who hold shares of Centre common stock as part of a hedge, straddle, constructive sale, conversion transaction or other integrated investment.

The discussion applies only to U.S. holders of shares of Centre common stock who hold such shares as a capital asset within the meaning of Section 1221 of the Code (generally, property held for investment). For purposes of this discussion, the term "U.S. holder" means a beneficial owner of Centre common stock that is for U.S. federal income tax purposes (1) an individual citizen or resident of the United States, (2) a corporation (or other entity taxable as a corporation for U.S. federal income tax purposes) created or organized in or under the laws of the United States, any state thereof or the District of Columbia, (3) a trust if (a) a court within the United States is able to exercise primary supervision over the administration of the trust and one or more U.S. persons (within the meaning of Section 7701(a)(30) of the Code) have the authority to control all substantial decisions of the trust or (b) such trust has in effect a valid election to be treated as a U.S. person for U.S. federal income tax purposes, or (4) an estate the income of which is includible in gross income for U.S. federal income tax purposes regardless of its source.

If a partnership (including any other entity or arrangement treated as a partnership for U.S. federal income tax purposes) holds Centre common stock, the tax treatment of a partner in the partnership generally will depend on the status of the partner and the activities of the partnership. Any partnership (or other entity or arrangement treated as a partnership for U.S. federal income tax purposes) that holds Centre common stock, and any partners in such partnership, should consult their tax advisors regarding the tax consequences of the merger to their specific circumstances.

 **Determining the actual tax consequences of the merger to you may be complex and will depend on your specific situation. You should consult with your own independent tax advisor as to the specific tax consequences of the merger in your particular circumstances, including the applicability and effect of the alternative minimum tax and any state, local, foreign and other tax laws and of possible changes in those laws after the date of this proxy statement/prospectus.** 

#### Tax Consequences of the Merger Generally
In connection with the filing with the SEC of the registration statement of which this proxy statement/prospectus is a part, Alston & Bird, counsel to Bank First, has rendered its tax opinion to Bank First, and Barack Ferrazzano Kirschbaum & Nagelberg, counsel to Centre, has rendered its tax opinion to Centre, in each case to the effect that the merger will qualify as a "reorganization" within the meaning of Section 368(a) of the Code. Copies of such tax opinions are attached as Exhibits 8.1 and 8.2 to the registration statement.

The obligations of the parties to complete the merger are conditioned on, among other things, the receipt by Bank First and Centre of tax opinions from Alston & Bird and Barack Ferrazzano Kirschbaum & Nagelberg, respectively, dated the closing date of the merger, to the effect that the merger will be treated as a reorganization within the meaning of Section 368(a) of the Code. The conditions relating to receipt of such closing tax opinions may be waived by both Bank First and Centre. Neither Bank First nor Centre currently intends to waive this condition to its obligation to consummate the merger. If either Bank First or Centre waives this condition after this registration statement is declared effective by the SEC, and if the tax consequences of the merger to Centre shareholders have materially changed, Bank First and Centre will recirculate appropriate materials to resolicit the votes of Centre shareholders.

The opinions of Alston & Bird and Barack Ferrazzano Kirschbaum & Nagelberg provided to Bank First and Centre, respectively, are and will be subject to customary qualifications and assumptions, including assumptions regarding the absence of changes in material facts and completion of the merger strictly in accordance with the merger agreement and the registration statement of which this proxy statement/prospectus forms a part. In rendering their legal opinions, Alston & Bird and Barack Ferrazzano Kirschbaum & Nagelberg will rely on representations and covenants of Bank First and Centre, including those representations contained in certificates of officers of Bank First and Centre, reasonably satisfactory in form and substance to each such counsel, and will assume that such representations are true, correct and complete without any regard to any knowledge limitation and that such covenants will be complied with. If any of these assumptions or representations are or become inaccurate in any way, or any of the covenants are not complied with, these opinions could be adversely affected. The opinions represent each counsel's best legal judgment but have no binding effect or official status of any kind, and no assurance can be given that contrary positions will not be taken by the IRS or a court considering the issues. Bank First and Centre have not sought and will not seek any ruling from the IRS regarding any matters relating to the merger, and as a result, there can be no assurance that the IRS will not assert, or that a court would not sustain, a position contrary to any of the conclusions set forth below or described in the tax opinions.

The following discussion assumes that the merger qualifies as a "reorganization" within the meaning of Section 368(a) of the Code.

#### U.S. Holders that Exchange Centre Common Stock for Bank First Common Stock
Subject to the discussion below relating to the receipt of cash in lieu of fractional shares of Bank First common stock, a U.S. holder that exchanges Centre common stock for shares of Bank First common stock in the merger:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • would generally not recognize any gain or loss on the exchange;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • would generally have an aggregate tax basis in the Bank First common stock received in the merger (including any fractional share of Bank First common stock deemed received and exchanged for cash, as described below) equal to its aggregate tax basis in the Centre common stock surrendered in exchange therefor; and

------

[**TABLE OF CONTENTS**](#TOC2)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • would generally have a holding period for the shares of Bank First common stock received in the merger (including any fractional share of Bank First common stock deemed received and exchanged for cash, as discussed below) that includes its holding period for its shares of Centre common stock surrendered in exchange therefor.

If a U.S. holder acquired different blocks of Centre common stock at different times or at different prices, the adjusted tax basis and holding period for Bank First common stock such holder receives in the merger would be determined on a block-for-block basis depending on the adjusted tax basis and holding period of the blocks of Centre common stock surrendered in exchange therefor. U.S. holders should consult their tax advisors regarding the manner in which shares of Bank First common stock should be allocated among different blocks of their Centre common stock surrendered in the merger.

#### Cash In Lieu of Fractional Shares
If a U.S. holder receives cash in lieu of a fractional share of Bank First common stock, the U.S. holder would generally be treated as having received such fractional share of Bank First common stock in the merger and then as having exchanged the fractional share for cash. Accordingly, the U.S. holder generally would recognize gain or loss equal to the difference between the amount of cash received in exchange for such fractional share and the U.S. holder's tax basis allocable to the fractional share of Bank First common stock. Such gain or loss generally would be capital gain or loss and would be long-term capital gain or loss if, as of the effective time of the merger, the U.S. holder's holding period for such fractional share (including the holding period of shares of Centre common stock surrendered therefor, as discussed above) exceeds one year. Long-term capital gain of non-corporate taxpayers, including individuals, is generally taxed at preferential rates. The deductibility of capital losses is subject to limitations. In addition, gain recognized by non-corporate taxpayers may be subject to the net investment income tax. See "— *Net Investment Income Tax*" below.

#### Shareholders Exercising Dissenters' Rights
Upon its exercise of dissenters' rights, a U.S. holder of Centre common stock would exchange all of its Centre common stock for cash. Accordingly, such U.S. holder would generally recognize gain or loss equal to the difference between the amount of cash received and such U.S. holder's adjusted tax basis in its Centre common stock. This gain or loss generally would be capital gain or loss and would be long-term capital gain or loss if the U.S. holder's holding period for its shares of Centre common stock exceeds one year. Long-term capital gain of non-corporate taxpayers, including individuals, is generally taxed at preferential rates. The deductibility of capital losses is subject to limitations. In addition, gain recognized by non-corporate taxpayers may be subject to the net investment income tax. See "— *Net Investment Income Tax*" below.

#### Net Investment Income Tax
A non-corporate U.S. holder of Centre common stock is generally subject to an additional 3.8% tax on the lesser of (1) the holder's "net investment income" (as defined in the Code) for the relevant taxable year or (2) the excess of the holder's modified adjusted gross income for the taxable year over a certain threshold which depends on the individual's U.S. federal income tax filing status. Net investment income generally would include any capital gain recognized in connection with the merger or due to the exercise of dissenters' rights. U.S. holders should consult their tax advisors as to the application of this additional tax to their circumstances.

#### Potential Dividend Treatment
In some cases, if a U.S. holder of Centre common stock actually or constructively owns shares of Bank First common stock (other than the Bank First common stock received as consideration in connection with the merger), the U.S. holder's gain realized could be treated as having the effect of the distribution of a dividend under the tests set forth in Section 302 of the Code, in which case such gain would be taxable as dividend income to the extent of the U.S. Holder's ratable share of Bank First's accumulated earnings and profits as calculated for U.S. federal income tax purposes. The determination of whether a U.S. holder will recognize capital gain or dividend income as a result of its exchange of Centre common stock in the merger is complex and must be determined on a shareholder-by-shareholder basis. Accordingly, each U.S. holder should consult its own independent tax advisor as to the tax consequences of the merger, including such determination, in its particular circumstances.

#### Backup Withholding
Backup withholding at the applicable rate (currently 24%) may apply with respect to certain cash payments to a U.S. holder of Centre common stock unless the holder:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • furnishes a correct taxpayer identification number, certifies that it is not subject to backup withholding and otherwise complies with all the applicable requirements of the backup withholding rules; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • provides proof that it is otherwise exempt from backup withholding.

Any amounts withheld under the backup withholding rules are not an additional tax and would generally be allowed as a refund or credit against the U.S. holder's U.S. federal income tax liability, provided the holder timely furnishes the required information to the IRS.

#### Certain Reporting Requirements
If a U.S. holder that receives Bank First common stock in the merger is considered a "significant holder," such U.S. holder would be required to retain records pertaining to the merger and to file with such holder's U.S. federal income tax return for the year in which the merger takes place a statement setting forth certain facts relating to the merger, including such U.S. holder's tax basis in and the fair market value of the Centre common stock and securities surrendered in the merger. A "significant holder" is any holder of Centre common stock that, immediately before the merger, (1) owned at least 1% (by vote or value) of the outstanding shares of Centre common stock, or (2) owned Centre common stock and securities with a tax basis of $1 million or more.

 **This discussion of certain material U.S. federal income tax consequences does not purport to be a complete analysis of all potential tax consequences of the merger. It is for general information purposes only and is not intended to be and does not constitute tax advice. Holders of Centre common stock are urged to consult their tax advisors as to the U.S. federal income tax consequences of the merger (or exercise of dissenters' rights) in light of their particular situations, as well as any tax consequences arising under any other U.S. federal tax laws, or under the laws of any state, local, foreign or other taxing jurisdiction or under any applicable tax treaty. Holders of Centre common stock are also urged to consult their tax advisors with respect to the effect of possible changes in any of those laws after the date of this proxy statement/prospectus.**

#### Independent Auditor's Report
Audit Committee

Centre 1 Bancorp, Inc. and Subsidiaries

Beloit, Wisconsin

#### Opinions on the Consolidated Financial Statements and Internal Control over Financial Reporting
We have audited the consolidated financial statements of Centre 1 Bancorp, Inc. and Subsidiaries (the "Company"), which comprise the balance sheets as of December 31, 2024 and 2023, and the related statements of income, comprehensive income, stockholders' equity, and cash flows for the years then ended, and the related notes to the financial statements. In our opinion, the accompanying consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2024 and 2023, and the results of its operations and its cash flows for the years then ended in accordance with accounting principles generally accepted in the United States of America.

We also have audited the Company's internal control over financial reporting as of December 31, 2024, based on criteria established in the Internal Control — Integrated Framework (2013), issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2024, based on COSO.

#### Basis for Opinions
We conducted our audits in accordance with auditing standards generally accepted in the United States of America (GAAS). Our responsibilities under those standards are further described in the "Auditor's Responsibilities for the Audits of the Consolidated Financial Statements and Internal Control over Financial Reporting" section of our report. We are required to be independent of the Company and to meet our other ethical responsibilities, in accordance with the relevant ethical requirements relating to our audits. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our audit opinions.

#### Responsibilities of Management for the Consolidated Financial Statements and Internal Control over Financial Reporting
Management is responsible for the preparation and fair presentation of the consolidated financial statements in accordance with accounting principles generally accepted in the United States of America and for the design, implementation, and maintenance of effective internal control over financial reporting relevant to the preparation and fair presentation of financial statements that are free from material misstatement, whether due to fraud or error. Management also is responsible for its assessment about the effectiveness of internal control over financial reporting, included in the accompanying Management Report.

In preparing the financial statements, management is required to evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the Company's ability to continue as a going concern within one year after the date that these financial statements are available to be issued.

Forvis Mazars, LLP is an independent member of Forvis Mazars Global Limited

[**TABLE OF CONTENTS**](#TOC5)

#### Auditor's Responsibilities for the Audits of the Financial Statements and Internal Control over Financial Reporting
Our objectives are to obtain reasonable assurance about whether the consolidated financial statements as a whole are free from material misstatement, whether due to fraud or error, and about whether effective internal control over financial reporting was maintained in all material respects, and to issue an auditor's report that includes our opinions.

Reasonable assurance is a high level of assurance but is not absolute assurance and therefore is not a guarantee that an audit of consolidated financial statements or an audit of internal control over financial reporting conducted in accordance with GAAS will always detect a material misstatement or a material weakness when it exists. The risk of not detecting a material misstatement resulting from fraud is higher than for one resulting from error, as fraud may involve collusion, forgery, intentional omissions, misrepresentations, or the override of internal control. Misstatements are considered to be material if there is a substantial likelihood that, individually or in the aggregate, they would influence the judgment made by a reasonable user based on the consolidated financial statements.

In performing an audit of consolidated financial statements and an audit of internal control over financial reporting in accordance with GAAS, we:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Exercise professional judgment and maintain professional skepticism throughout the audits.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Identify and assess the risks of material misstatement of the consolidated financial statements, whether due to fraud or error, and design and perform audit procedures responsive to those risks. Such procedures include examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Obtain an understanding of internal control relevant to the consolidated financial statement audit in order to design audit procedures that are appropriate in the circumstances.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Obtain an understanding of internal control over financial reporting relevant to the audit of internal control over financial reporting, assess the risks that a material weakness exists, and test and evaluate the design and operating effectiveness of internal control over financial reporting based on the assessed risk.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Evaluate the appropriateness of accounting policies used and the reasonableness of significant accounting estimates made by management, as well as evaluate the overall presentation of the consolidated financial statements.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Conclude whether, in our judgment, there are conditions or events, considered in the aggregate, that raise substantial doubt about the Company's ability to continue as a going concern for a reasonable period of time.

We are required to communicate with those charged with governance regarding, among other matters, the planned scope and timing of the audit, significant audit findings, and certain internal control-related matters that we identified during the consolidated financial statement audit.

#### Definition and Inherent Limitations of Internal Control over Financial Reporting
An entity's internal control over financial reporting is a process effected by those charged with governance, management, and other personnel, designed to provide reasonable assurance regarding the preparation of reliable consolidated financial statements in accordance with accounting principles generally accepted in the United States of America. Because management's assessment and our audit were conducted to meet the reporting requirements of Section 112 of the *Federal Deposit Insurance Corporation Improvement Act* (FDICIA), our audit of the Company's internal control over financial reporting included controls over the preparation of the Company's consolidated financial statements in accordance with accounting principles generally accepted in the United States of America and controls over the preparation of schedules equivalent to the basic financial statements in accordance with the Federal Financial Institutions Examination Council Instructions for Consolidated Reports of Condition and Income (Call Report Instructions).

------

[**TABLE OF CONTENTS**](#TOC5)

An entity's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the entity; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of consolidated financial statements in accordance with accounting principles generally accepted in the United States of America, and that receipts and expenditures of the entity are being made only in accordance with authorizations of management and those charged with governance; and (3) provide reasonable assurance regarding prevention or timely detection and correction of unauthorized acquisition, use, or disposition of the entity's assets that could have a material effect on the consolidated financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent, or detect and correct, misstatements. Also, projections of any assessment of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

#### Other Information Included in the Annual Report
Management is responsible for the other information included in the annual report*.* The other information comprises the information included in the annual report but does not include the consolidated financial statements and our auditor's report thereon. Our opinion on the consolidated financial statements does not cover the other information, and we do not express an opinion or any form of assurance thereon.

In connection with our audit of the consolidated financial statements, our responsibility is to read the other information and consider whether a material inconsistency exists between the other information and the financial statements, or the other information otherwise appears to be materially misstated. If, based on the work performed, we conclude that an uncorrected material misstatement of the other information exists, we are required to describe it in our report.

#### Centre 1 Bancorp, Inc. and Subsidiaries Notes to Consolidated Financial Statements As of and for the Years Ended December 31, 2024 and 2023 (dollars in thousands)
1. Summary of Significant Accounting Policies

#### Nature of Banking Activities
Centre 1 Bancorp, Inc. (the "Company") is a financial holding company providing community banking through its wholly-owned subsidiary, First National Bank and Trust Company (the "Bank"), headquartered in Beloit, Wisconsin. The Bank grants commercial, residential and consumer loans, accepts deposits and provides trust services to customers primarily in southern Wisconsin and northern Illinois. The Bank is subject to competition from other financial institutions and nonfinancial institutions providing financial products. Additionally, the Company and the Bank are subject to the regulations of certain regulatory agencies and undergo periodic examination by those regulatory agencies.

#### Consolidation
The consolidated financial statements include the accounts of the Company and the Bank. The consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America ("U.S. GAAP") and conform to general practices within the banking industry. All significant intercompany accounts and transactions have been eliminated in the consolidated financial statements.

#### Use of Estimates
In preparing consolidated financial statements in conformity with U.S. GAAP, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheet and reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses and the valuation allowance for deferred tax assets, if necessary.

#### Cash and Cash Equivalents
For purposes of reporting cash flows, cash and cash equivalents include cash and amounts due from banks and federal funds sold, all of which mature within ninety days.

The Company maintains amounts due from banks which often exceed federally insured limits. The Company has not experienced any losses in such accounts. At December 31, 2024 cash exceeding federally insured limits totaled $75,183. Of that amount, $47,149 was held at the Federal Reserve Bank.

#### Investment Securities — Available for Sale
Investments classified as available for sale are securities that the Company intends to hold for an indefinite period of time, but not necessarily to maturity. Any decision to sell a security classified as available for sale would be based on various factors, including movements in interest rates, changes in the maturity mix of the Company's assets and liabilities, liquidity needs, regulatory capital considerations, and other similar factors. Securities classified as available for sale are carried at fair value. Unrealized gains or losses are reported as increases or decreases in other comprehensive income, net of the related deferred tax effect. Realized gains or losses and unrealized losses related to credit losses deemed to be other-than-temporary, determined on the basis of the cost of specific securities, are included in earnings. Purchase premiums and discounts are recognized in interest income using the effective interest method over the terms of the securities. The Company has elected to record time deposits held in other financial institutions at fair value and includes these instruments in securities available for sale.

#### Centre 1 Bancorp, Inc. and Subsidiaries Notes to Consolidated Financial Statements As of and for the Years Ended December 31, 2024 and 2023 (dollars in thousands)

#### Investment Securities — Held to Maturity
Investments classified as held to maturity are securities the Company has both the intent and ability to hold to maturity regardless of changes in market conditions, liquidity needs or changes in general economic conditions. These securities are carried at cost, adjusted for amortization of premium and accretion of discount, over their contractual lives. The sale of a security within three months of its maturity date or after collection of at least 85 percent of the principal outstanding at the time the security was acquired is considered a maturity for purposes of classification and disclosure.

Management measures expected credit losses on held to maturity debt securities on a collective basis. No reserve for expected credit losses has been recorded as of December 31, 2024. The estimate of expected credit losses considers historical credit loss information that is adjusted for current conditions and reasonable and supportable forecasts.

#### Loans Held-for-Sale
Loans originated and intended for sale in the secondary market are carried at the lower of cost or estimated market value in the aggregate. Due to the short-term nature of these loans, the carrying amount approximates fair value. Net unrealized losses, if any, are recognized through a valuation allowance by charges to income. There were no valuation allowances necessary as of December 31, 2024 and 2023. All sales are made without recourse. The Bank also services loans that have been sold with servicing retained. A gain or loss is recognized at the time of the sale reflecting the present value if the difference between the contractual interest rate of the loans sold and the yield to the investor, adjusted for the initial value of the mortgage servicing rights associated with the loans sold with servicing retained. Such loans are not included in the consolidated balance sheets. Gains and losses on sales of mortgage loans held for sale are included in Mortgage banking income, net.

#### Loans Receivable
Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at the amount of unpaid principal, reduced by the allowance for loan losses. Interest income is accrued on the unpaid principal balance. Loan origination fees, net of certain direct loan origination costs, are deferred and recognized as an adjustment of the loan yield using an effective interest rate method. The accrual of interest income on impaired loans is discontinued when, in the opinion of management, there is reasonable doubt as to the borrower's ability to meet payment of interest or principal when they become due (generally at 90 days past due). When the interest accrual is discontinued, all unpaid accrued interest is reversed. Cash collections on impaired loans are credited to the loan receivable balance and no interest income is recognized on those loans until the principal balance is current. Loans are returned to accrual status when the principal and interest amounts contractually due are brought current and future payments are reasonably assured.

A troubled loan modification (TLM) includes a loan modification where a borrower is experiencing financial difficulty, and the Bank grants a concession to that borrower that we would not otherwise consider except for the borrower's financial difficulties. These modifications may be granted in the form of principal forgiveness, interest rate reduction, other-than-insignificant payment delay or other-than-significant term extension. A TLM may be either accrual or non-accrual status based upon the performance of the borrower and management's assessment of collectability. If a TLM is placed on non-accrual status, it remains there until a sufficient period of performance under the restructured terms has occurred at which time it is returned to accrual status, generally six months.

Closed-end retail loans that become 120 days past due and open-end retail loans that become 180 days past due will be classified as loss and charged off. Retail loans with non-real estate collateral may be written down to the value of the collateral, less cost to sell.

Retail loans in bankruptcy should be classified Loss and charged off within 60 days of receipt of the notification of filing from the bankruptcy court. Loans with collateral may be written down to the value of the collateral, less cost to sell. Other periodic and single payment loans which are ninety (90) days past due whose related collateral has been repossessed and for which there is no possibility for renewal or payments shall be charged off.

#### Allowance for Credit Losses
The allowance for credit losses is established as losses are estimated to have occurred through a provision for credit losses charged to earnings. Credit losses are charged against the allowance for credit losses when management believes the uncollectability of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance for credit losses. The allowance for credit losses is adequate to cover probable credit losses relating to specifically identified loans, as well as probable credit losses inherent in the balance of the loan portfolio. The allowance for credit losses is based on past events and current economic conditions and does not include the effects of expected losses on specific loans or groups of loans that are related to future events or expected changes in economic conditions. While management uses the best information available to make its evaluation, future adjustments to the allowance for credit losses may be necessary if there are significant changes in economic conditions. The allowance is comprised of both a specific reserve component and a general reserve component. The company has elected to exclude accrued interest receivable from its calculation of the allowance for credit losses.

The specific reserve relates to all individually evaluated loans for which the allowance for credit losses is estimated on a loan-by-loan basis. A loan is considered an individually evaluated loan when, based on current information and events, it is probable that the Bank will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Impairment is measured on a loan-by-loan basis as the excess of amortized cost over the present value of expected future cash flows discounted at the loan's effective interest rate, the loan's obtainable market price, or the fair value of the collateral if the loan is collateral dependent.

The Company qualitatively adjusts model results for risk factors that are not considered within the modeling processes but are nonetheless relevant in assessing the expected credit losses within the loan pools. These qualitative factors and other qualitative adjustments may increase or decrease the Company's estimate of expected credit losses by a calculated percentage or amount based upon the estimated level of risk. The various risks that may be considered in making qualitative adjustments include, among other things, the impact of environmental factors such as (i) changes in the nature, volume and terms of loans, (ii) changes in lending personnel, (iii) changes in the quality of the loan review function, (iv) changes in nature and volume of past-due, non-accrual and/or classified loans, (v) changes in concentration of credit risk, (vi) changes in economic and industry conditions, (vii) changes in legal and regulatory requirements, (viii) unemployment and inflation statistics, and (ix) changes in underlying collateral values.

A discounted cash flow method is used for each loan in a pool and the results are aggregated at the pool level. The analysis produces expected cash flows for each instrument in the pool by pairing loan-level term information, e.g., maturity date, payment amount, interest rate, and etc., with top-down pool assumptions, e.g., default rates and prepayment speeds. The Company's portfolio segments are discussed in Note 6.

In determining the proper level of the allowance for credit losses, the Company determined that the loss experience provides the best basis for the assessment of expected credit losses. The Company therefore used historical credit loss experience by each loan segment over an economic cycle. For most of the segment models for collectively evaluated loans, the Company incorporated two or more macroeconomic drivers using a statistical regression modeling methodology.

In addition, various regulatory agencies periodically review the allowance for credit losses. These agencies may require the Company to make additions to the allowance for credit losses based on their judgments of collectability based on information available to them at the time of their examination.

#### Allowance for Credit Losses — Off-Balance Sheet Credit Exposures
The allowance for credit losses on off-balance sheet credit exposures is a liability account, representing expected credit losses over the contractual period for which the Company is exposed to credit risk resulting from a contractual obligation to extend credit. No allowance is recognized if the Company has the unconditional right to cancel the obligation. The allowance is reported as a component of accrued interest payable and other liabilities (or as a separate line if material) in the consolidated balance sheets. Adjustments to the allowance are reported in the consolidated income statement as a component of credit loss expense. The Company has recorded an allowance for credit losses for off-balance sheet exposures of $971 and $1,069 at December 31, 2024 and 2023, respectively.

#### Leases
The Company determines if a lease is present at the inception of an agreement. Right-of-use ("ROU") assets and lease liabilities are recognized at lease commencement based on the present value of the remaining lease payments using a discount rate that represents the Company's incremental borrowing rate at the lease commencement date. ROU assets and operating lease liabilities are included in other assets and other liabilities, respectively, on the consolidated balance sheets. Leases with original terms of 12 months or less are recognized in profit or loss on a straight-line basis over the lease term.

Operating lease ROU assets represent the Company's right to use an underlying asset during the lease term and operating lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease expense, which is comprised of amortization of the ROU asset and the implicit interest accreted on the operating lease liability, is recognized on a straight-line basis over the lease term and is recorded in occupancy expenses in the consolidated statements of income.

The Company's leases relate primarily to office space, and some contain options to renew the lease. These options to renew are generally not considered reasonably certain to exercise and are therefore not included in the lease term until such time that the option to renew is reasonably certain.

#### Transfers of Financial Assets
Transfers of financial assets are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity.

#### Premises and Equipment
Land is carried at cost. Depreciable assets are stated at cost less accumulated depreciation. Provisions for depreciation are computed on straight-line and accelerated methods over the estimated useful lives of the assets, which range from 15 to 40 years for buildings and 3 to 10 years for furniture and fixtures.

#### Goodwill and Core Deposit Intangibles
The Bank accounts for goodwill and core deposit intangibles in accordance with the Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) 350-10, *Goodwill and Other Intangible Assets*.

------

[**TABLE OF CONTENTS**](#TOC5)

#### Centre 1 Bancorp, Inc. and Subsidiaries Notes to Consolidated Financial Statements As of and for the Years Ended December 31, 2024 and 2023 (dollars in thousands)
This Statement provides that goodwill and indefinite lived intangible assets are reviewed at least annually for impairment. An impairment review is designed to determine whether the fair value, and the related recorded goodwill, is below its carrying value. Management has conducted the annual impairment review and determined that the carrying value of goodwill has not been impaired. Accordingly, there were no charges to operations for goodwill impairment. If goodwill was impaired, the impairment would be measured by the amount by which the carrying amount of the goodwill exceeds the implied fair value of the goodwill.

Core deposit intangibles are amortized over 10 years using the straight-line method.

#### Federal Home Loan Bank (FHLB) Stock
The Bank's investment in Federal Home Loan Bank (FHLB) stock meets the minimum amount required by current regulations and is carried at cost, which approximates fair value. FHLB stock is included in FRB and FHLB stock, at cost on the consolidated balance sheets.

#### Mortgage Servicing Rights
Mortgage servicing rights are recognized as separate assets when the loans are sold with servicing retained. Servicing rights resulting from the sale of loans originated by the Bank are initially measured at fair value at the date of transfer. The Bank subsequently measures servicing rights using the fair value method. Under the fair value method, the serving rights are carried in the consolidated balance sheet at fair value and the changes in fair value are reported in earnings in the period in which the changes occur. Fair value is determined using prices for similar assets with similar characteristics, when available, or discounted cash flows using market based assumptions such as prepayment speeds, interest rates, and other factors which are subject to change over time. Mortgage servicing rights are included in other intangible assets, net on the consolidated balance sheets and totaled $4,176 and $4,168 at December 31, 2024 and 2023, respectively. At December 31, 2024 and 2023, the unpaid balances of mortgage loans serviced for others was $333,021 and $325,758, respectively. The change in fair value of the mortgage servicing right was not material to the consolidated financial statements.

#### Real Estate Owned, Net
Assets acquired through, or in lieu of, foreclosure are held for sale and initially recorded at fair value less cost to sell at the date of foreclosure, establishing a new cost basis. Subsequent to foreclosure, valuations are periodically performed by management and the assets are carried at the lower of market value or carrying amount less cost to sell. When applicable, revenue and expenses from operations and changes in the valuation are included in net expenses from foreclosed assets. Revenue and expenses from operations and changes in the valuations for the years ended December 31, 2024 and 2023 was $0.

#### Stock- Related Compensation
The Company has stock-based employee compensation plans which are described more fully in Note 12. The Company has adopted the fair value recognition provisions of FASB ASC 718-10, *Stock Compensation*, for the options granted under the 2002 Stock Incentive Plan. Net compensation cost amounted to $0 and $0 in 2024 and 2023, respectively, for options granted under the 2002 Stock Incentive Plan. The Company also issues restricted stock units to employees and directors. Compensation cost recognized on restricted stock is reflected in net income based on the fair market value of the shares at the date of grant and the related shares that are released from restriction. Compensation cost related to restricted stock for the years ended December 31, 2024 and 2023 was $852 and $872, respectively.

#### Income Taxes
For the years ended December 31, 2024 and 2023, respectively, the Company has filed or expects to file consolidated federal and combined state income tax returns. Income tax expense is based on the liability method. Deferred income tax assets and liabilities are computed annually for differences between the financial statement and tax bases of assets and liabilities that will result in taxable or deductible amounts in the future based on enacted tax laws and rates applicable to the periods in which the differences are expected to affect taxable income. As changes in tax laws or rates are enacted, deferred tax assets and liabilities are adjusted through the provision for income taxes. See Note 13 for additional information on deferred tax assets and liabilities. Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized.

The Company's policy is to recognize interest related to income tax issues as components of income tax expense. The Company recognizes accrued interest and penalties related to unrecognized tax benefits in income tax expense.

#### Profit-Sharing Plan
The Company has established a defined contribution 401(k) profit-sharing plan for qualified employees. The Company's policy is to fund Company contributions annually as approved.

#### Supplemental Retirement Plan
The Company has a non-qualified unfunded supplemental retirement plan (the "SERP") covering specific executive officers. Benefits provided under the SERP are based on years of service and the employee's final average pay, which is defined as the average salary and bonus for the highest three years of the five years preceding termination of employment.

The Company records annual amounts relating to the SERP based on calculations that incorporate assumptions including discount rates, retirement dates, assumed rates of return, and compensation increases. The Company reviews its assumptions on an annual basis and makes modifications to the assumptions based on current rates and trends where appropriate to do so. Management of the Bank believes that the assumptions utilized in recording its obligations under the SERP are appropriate based on its experience and market conditions. The liability for deferred compensation expense is included in other liabilities on the consolidated balance sheet.

#### Off-Balance Sheet Financial Instruments
In the ordinary course of business, the Bank has entered into off-balance-sheet financial instruments consisting of commitments to extend credit, commitments under credit card arrangements, commercial letters of credit and standby letters of credit. Such financial instruments are recorded in the consolidated financial statements when they are funded or related fees are incurred or received.

#### Derivative Financial Instruments
The Bank utilizes derivative financial instruments to meet the ongoing credit needs of its customers and in order to manage the market exposure of its residential loans held for sale and its commitments to extend credit for residential loans. Derivative financial instruments include commitments to extend credit and forward mortgage loan sales commitments. The Bank does not use interest rate contracts (e.g. swaps, caps, floors) or other derivatives to manage interest rate risk and had none of the instruments outstanding at December 31, 2024 and 2023.

#### Trust Income
Property held for customers in trust or agency capacities is not included in the accompanying consolidated balance sheets since such items are not assets of the Bank. In accordance with established industry practice, income from trust fees and other fiduciary income is reported on a cash basis. Reporting of trust fees on an accrual basis would have no material effect on reported income.

#### Earnings Per Share
Earnings per share is computed based upon the weighted average number of common shares outstanding during each year. In the computation of diluted earnings per share, all dilutive stock options and restricted stock outstanding is assumed to be exercised at the beginning of each year and the proceeds are used to acquire shares of the Company's common stock at the average market price during the year.

#### Bank-Owned Life Insurance
The Company owns insurance on the lives of a certain group of current and former employees. The cash surrender value of these policies is included as an asset on the consolidated balance sheets and any increases in the cash surrender value are recorded as tax-free noninterest income on the consolidated statements of income. In the event of the death of an insured individual covered by these policies, after distribution to the insured beneficiaries, when applicable, the Company receives a tax-free death benefit, which is recorded as noninterest income.

#### Comprehensive Income
Comprehensive income consists of net income and other comprehensive income. Other comprehensive income includes unrealized gains and losses on investment securities available for sale which is recognized as separate components of equity.

#### Revenue from Contracts with Customers
The Company records revenue from contracts with customers in accordance with ASC Topic 606, "Revenue from Contracts with Customers" ("Topic 606"). Under Topic 606, the Company must identify the contract with a customer, identify the performance obligations in the contract, determine the transaction price, allocate the transaction price to the performance obligations in the contract, and recognize revenue when (or as) the Company satisfies a performance obligation.

A significant component of the Company's revenue, net interest earned on financial assets and liabilities, is excluded from the scope of Topic 606. The Company generally fully satisfies its performance obligations on its contracts with customers as services are rendered and the transaction prices are typically fixed; charged either on a periodic basis or based on activity. Because performance obligations are satisfied as services are rendered and the transaction prices are fixed, the Company has made no significant judgments in applying the revenue guidance prescribed in Topic 606 that affect the determination of the amount and timing of revenue from contracts with customers.

#### Recently Adopted Accounting Standards
On January 1, 2023, the Company adopted ASU 2016-13, Financial Instruments — Credit Losses (Topic 326) Measurement of Credit Losses on Financial Instruments, as amended, which replaces the incurred loss methodology with an expected loss methodology that is referred to as the current expected credit loss (CECL) methodology. The measurement of expected credit losses under the CECL methodology is applicable to financials assets measured at amortized cost, including loan receivables and held-to-maturity debt securities. It also applies to off-balance sheet credit exposures not accounted for as insurance (loan commitments, standby letters of credit, financial guarantees, and other similar instruments) and net investments in leases recognized by a lessor in accordance with Topic 842 on leases. In addition, ASC 326 makes changes to the accounting for available-for-sale debt securities. One such change is to require credit losses to be presented as an allowance rather than as a write-down on available-for-sale debt securities management does not intend to sell or believes that it is more likely than not they will be required to sell.

#### Subsequent Events
The Company and the Bank evaluated its December 31, 2024 consolidated financial statements through March 19, 2025, the date these consolidated financial statements were available for issuance for items that should potentially be recognized or disclosed.

2. Cash and Due From Banks

Effective March 26, 2020, the Federal Reserve Board reduced reserve requirements to zero percent and eliminated the need to maintain balances at the Federal Reserve Bank to satisfy reserve requirements. Therefore, at December 31, 2024 and 2023, there were no reserve requirements with the Federal Reserve Bank.

3. #### Fair Value of Measurements
The Bank measures certain assets and provides disclosures in accordance with guidance related to fair value measurements. This guidance establishes a framework for measuring fair value and expands disclosures about fair value measurements. Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price) and establishes a framework for measuring fair value.

The Bank utilizes market data or assumptions that market participants would use in pricing the asset or liability, including assumptions about risk and the risks inherent in the inputs to the valuation technique. These inputs can be readily observable, market corroborated, or generally unobservable. The Bank is able to classify fair value balances based on the observability of those inputs. The guidance establishes a fair value hierarchy that prioritizes the inputs used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurement) and the lowest priority to unobservable inputs (Level 3 measurement). The three levels of the fair value hierarchy are as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Level 1 — Fair value is based upon quoted prices (unadjusted) for identical assets or liabilities in active markets. Active markets are those in which transactions for the asset or liability occur in sufficient frequency and volume to provide pricing information on an ongoing basis.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Level 2 — Fair value is based upon quoted prices for similar, but not identical, assets and liabilities in active markets, and other inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument. This also includes quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability, or inputs that are derived principally from or corroborated by observable market data.

[**TABLE OF CONTENTS**](#TOC5)

#### Centre 1 Bancorp, Inc. and Subsidiaries Notes to Consolidated Financial Statements As of and for the Years Ended December 31, 2024 and 2023 (dollars in thousands)
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Level 3 — Fair value is based upon financial models using primarily unobservable inputs. Unobservable inputs reflect the Bank's own assumptions about the assumptions that market participants would use in pricing the asset or liability developed based on the best information available in the circumstances.

A financial instrument's categorization within the valuation hierarchy is based upon the lowest level or input that is significant to the fair value measurement.

The following is a description of the valuation methodologies used by the Bank for instruments measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy.

#### Investment Securities — Available for Sale
Where quoted prices for securities are available in an active market, those securities are classified within Level 1 of the valuation hierarchy. If such quoted market prices are not available, then fair values are estimated using pricing models, quoted prices of securities with similar characteristics, or discounted cash flows. Examples of securities with similar characteristics, which would generally be classified within Level 2 of the valuation hierarchy, include AAA-rated U.S. government sponsored agency securities and obligations of states and political subdivisions.

#### Mortgage Servicing Rights
The Bank adjusts mortgage servicing rights to fair value on a recurring basis. Where prices for similar assets with similar characteristics are available, mortgage servicing rights are classified within Level 2 of the valuation hierarchy. Since prices for similar assets are available, the Bank has classified these assets in Level 2.

#### Loans Held for Investment
The Bank does not record these loans at fair value on a recurring basis. However, from time to time, a loan is considered an individually evaluated loan and an allowance for credit losses is established. Loans for which it is probable that payment of interest and principal will not be made in accordance with the contractual terms of the loan agreement are considered a collateral dependent individually evaluated loan. Once a loan is identified as individually evaluated and collateral dependent, management measures impairment in accordance with relevant accounting guidance. The fair value of individually evaluated loans is estimated using one of several methods, including collateral value, market value of similar debt, enterprise value and liquidation value. Those individually evaluated loans not requiring an allowance represent loans for which the fair value of the expected repayments or collateral exceeds the recorded investments in such loans and for which the carrying amount will remain at amortized cost. Individually evaluated loans where an allowance is established based on fair value require classification in the fair value hierarchy. When the fair value is based on an observable market price or a current appraised value of the collateral, the Bank records the individually evaluated loan as a nonrecurring Level 3 valuation. At December 31, 2024 and 2023, substantially all of the total individually evaluated loans were evaluated based on the fair value of the collateral.

#### Real Estate Owned
Loans on which the underlying collateral has been repossessed are adjusted to fair value upon transfer to other real estate owned, establishing a new carrying value. Subsequently, other real estate owned is carried at the lower of carrying value or fair value. Fair value is based upon independent market prices, appraised values of the collateral or management's estimation of the value of the collateral. When the fair value of the collateral is based on an observable market price or a current appraised value, the Bank records the asset as a nonrecurring Level 3 valuation. The Bank had no other real estate owned at ended December 31, 2024 and 2023, respectively.

#### Assets Measured at Fair Value on Recurring Basis
The following table sets forth by level within the fair value hierarchy the Bank's financial assets that were accounted for at fair value on a recurring basis as of December 31, 2024 and 2023. Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The Bank's assessment of the significance of a particular input to the fair value measurement requires judgment and may affect the valuation of fair value assets and liabilities and their placement within the fair value hierarchy levels.

Management does not believe any individual unrealized loss as of December 31, 2024 and 2023 represents other than temporary impairment. The Company held 243 and 261 investment securities as of December 31, 2024 and 2023, respectively, that had unrealized losses existing for greater than 12 months.

For the Company's investments in each type of security having significant unrealized losses, without a recorded allowance for credit loss, note the following:

#### U.S. Treasury Obligations
The unrealized losses on the Company's investments in U.S. Treasury obligations were caused by market fluctuations and interest rate increases. The contractual terms of those investments do not permit the issuer to settle the securities at a price less than the amortized cost bases of the investments. Because the Company does not intend to sell the investments and it is not more likely than not the Company will be required to sell the investments before recovery of its amortized cost bases, which may be maturity, the Company has not recorded an allowance for credit losses at December 31, 2024.

#### Obligations of U.S. Government Sponsored Agencies
The unrealized losses on the Company's investments in direct obligations of U.S. Government agencies were caused by market fluctuations and interest rate increases. The contractual terms of those investments do not permit the issuer to settle the securities at a price less than the amortized cost bases of the investments. Because the Company does not intend to sell the investments and it is not more likely than not the Company will be required to sell the investments before recovery of its amortized cost bases, which may be maturity, the Company has not recorded an allowance for credit losses at December 31, 2024.

#### Residential Mortgage-Backed Securities and Collateralized Mortgage Obligations of Government Entities and Agencies
The unrealized losses on the Company's investment in residential mortgage-backed securities were caused by changes in interest rates. The Company expects to recover the amortized cost basis over the term of the securities. Because the decline in market value is attributable to changes in interest rates and not credit quality, and because the Company does not intend to sell the investments and it is not more likely than not the Company will be required to sell the investments before recovery of their amortized cost bases, which may be maturity, the Company has not recorded an allowance for credit losses at December 31, 2024.

#### Obligations of State and Political Subdivisions
The unrealized losses on the Company's investments in securities of state and political subdivisions were caused by market fluctuations and interest rate increases. The contractual terms of those investments do not permit the issuer to settle the securities at a price less than the amortized cost bases of the investments. Because the Company does not intend to sell the investments and it is not more likely than not the Company will be required to sell the investments before recovery of its amortized cost bases, which may be maturity, the Company has not recorded an allowance for credit losses at December 31, 2024.

#### Corporate Securities
The Company's unrealized loss on investments in other securities relates to $27,502 in domestic and foreign corporate bonds. The unrealized loss was primarily caused by market fluctuations and interest rate increases. The contractual terms of those investments do not permit the issuer to settle the securities at a price less than the amortized cost bases of the investments. Because the Company does not intend to sell the investment and it is more likely than not the Company will not be required to sell the investment before recovery of its amortized cost bases, which may be maturity, the Company has not recorded an allowance for credit losses at December 31, 2024.

Commercial loans and commercial real estate loans are evaluated for the adequacy of repayment sources at the time of approval and are regularly reviewed for any possible deterioration in the ability of the borrower to repay the loan.

The Bank evaluates the credit risk of each commercial customer on an individual basis and, where deemed appropriate, collateral is obtained. Collateral varies by the type of loan and individual loan customer and consists of general business assets such as real estate, equipment, receivables, and inventory. The Bank's access to collateral is dependent upon the type of collateral obtained.

Policies have been established that set standards for the maximum commercial real estate loan amount by type of property, loan terms, pricing structures, loan-to-value limits by property type, as well as policies and procedures for granting exceptions to established underwriting standards.

The Bank's residential real estate lending policies require all loans to have viable repayment sources. Residential real estate loans are evaluated for the adequacy of these repayment sources at the time of approval using such factors as credit scores, debt-to-income ratios, and collateral values. Home equity loans and lines of credit are generally governed by the same lending policies.

Origination activities for construction real estate loans, agricultural production loans and municipal loans are similar to those described above for commercial, real estate and residential real estate lending.

**<u>Credit Quality</u> —** The Bank utilizes a risk grading matrix on each loan. Loans are graded pass, special mention, substandard and doubtful. Loans are initially graded at origination, with updates occurring at renewal, with any new loan request, or whenever available information indicates a change in the borrower's credit quality sufficient to warrant a change in the risk rating. A description of the loan grades is as follows:

Pass — Loans rated 1-5 are considered "Pass" and consist of borrowers of generally high quality and character. Little to no risk probability. Balance sheets are very strong with superior liquidity, excellent debt capacity and low leverage. Cash flow trends are positive and stable.

Special Mention — Loans rated 6 are considered "Special Mention" and consist of marginal quality. Earnings are generally deteriorating, and cash flow is not consistently adequate to cover debt service under current terms. Loans are generally performing as agreed with minor delinquencies.

Substandard Accrual — Loans rated 7 are considered "Substandard Accrual" and consist of borrowers of poor quality. Unfavorable earnings performance or fiscal year end losses are present. Cash flow is generally insufficient to cover debt service under current terms. Loans are generally delinquent (regularly 60 days past due).

Substandard Non-Accrual — Loans rated 8 are considered "Substandard Non-Accrual" and consist of borrowers of poor quality. Unfavorable earnings performance and/or fiscal year end losses have been reported. Cash flow is not adequate to cover debt service under existing repayment terms. Secondary sources of repayment or guarantor support are also not sufficient to make scheduled payments. Loans are over 90 days delinquent. Loans are on non-accrual status and full repayment of the contractual principal and interest payments is in doubt.

Doubtful — Loans rated a 9 are considered "Doubtful" and consist of borrowers of the lowest quality. Consistent losses have been reported and cash flow is not adequate to cover debt service under current terms. Loans are regularly 90 days past due. Doubtful classification should be temporary as the loan should improve and be upgraded to at least Substandard Non-Accrual or it should be downgraded to Loss and charged off.

Troubled loan modification (TLM) includes a loan modification where a borrower is experiencing financial difficulty, and the Bank grants a concession to that borrower that we would not otherwise consider except for the borrower's financial difficulties. These modifications may be granted in the form of principal forgiveness, interest rate reduction, other-than-insignificant payment delay or other-than-significant term extension. A TLM may be either accrual or non-accrual status based upon the performance of the borrower and management's assessment of collectability. If a TLM is placed on non-accrual status, it remains there until a sufficient period of performance under the restructured terms has occurred at which time it is returned to accrual status, generally six months. As of December 31, 2024 and 2023, the Company had three and one TLM with a balance of $954 and $1,058 respectively, that was granted modification under the other-than-significant term extension form.

The Company continues to evaluate loans purchased for impairment in accordance with U.S. GAAP. The purchased loans were considered impaired at the acquisition date if there was evidence of deterioration since origination and if it was probable that not all contractually required principal and interest payments would be collected.

No loans modified to borrowers with financial difficulty subsequently defaulted in the past 12 months.

As of December 31, 2024 and 2023, the estimated contractually required payments receivable on credit impaired and non-credit impaired loans was $0 and $7,936 and $0 and $9,128, respectively. The cash flows expected to be collected related to principal as of December 31, 2024 and 2023 on all purchased loans is $7,936 and $9,128, respectively. Subsequent decreases to the expected cash flows will generally result in a provision for credit losses. Subsequent increases in cash flows will result in a reversal of the provision for credit losses charged to earnings to the extent of prior charges or a reclassification of the difference from non-accretable discount to accretable discount, with a positive impact on interest income. Further, any excess of cash flows expected over the estimated fair value is referred to as the accretable yield and is recognized in interest income over the remaining life of the loan when there is a reasonable expectation about the amount and timing of such cash flows.

Certain directors and executive officers of the Company and Bank, and their related interests, had loans outstanding in the aggregate amounts of $11,600 and $6,163 at December 31, 2024 and 2023, respectively. During 2024, there were no new loans made to directors and executive officers.

The Bank has a master contract agreement with the FHLB that provides for borrowing up to the maximum $148,214 and $111,556 at December 31, 2024 and 2023, respectively. The FHLB provides both fixed and floating rate advances. Fixed rate advances are priced in reference to market rates of interest at the time of the advance, namely the rates that the FHLB pays to borrowers at various maturities. Advances with call provisions permit the FHLB to request payment beginning on the call date and quarterly thereafter. Prepayments may be subject to penalties. Interest is payable monthly with principal payment due at maturity. FHLB advances are secured by qualifying mortgages of the Bank (such as residential mortgage and commercial real estate) and by specific investment securities for certain FHLB advances. The Bank had collateral capacity of $547,305 and $540,098 at December 31, 2024 and 2023, respectively, which is calculated at 35% of total assets as long as there is supported collateral.

[**TABLE OF CONTENTS**](#TOC5)

The Company formed a statutory trust under the laws of the state of Delaware (the Trust), which exists for the exclusive purposes of (i) issuing trust securities representing undivided beneficial interests in the assets of the Trust; (ii) investing the gross proceeds of the trust securities in junior subordinated deferrable interest debentures (subordinated debentures); and (iii) engaging in only those activities necessary or incidental thereto.

The accounting guidance applicable to such trusts requires the assets and liabilities, as well as the related income and expenses of the Trust, to be excluded from the Company's consolidated financial statements. However, the subordinated debentures issued by the Company and purchased by the Trust remain on the consolidated balance sheet. In addition, the related interest expense continues to be included in the consolidated income statement.

For regulatory capital purposes, these trust securities qualify as a component of Tier 1 Capital.

The debentures of $8,000 mature in 2039 and were not redeemable, except under limited circumstances, until January 29, 2015 at par. The adjustable rate was 8% until January 29, 2015 and thereafter resets every three months at the 3-month CME Term SOFR rate plus 2.20%. At December 31, 2024 and 2023, the interest rate on the adjustable, long-term debt was 7.71% and 7.84%, respectively.

The Bank has pledged collateral of $9,596 and $9,585 at December 31, 2024 and 2023, respectively to the Federal Reserve Bank to establish an available line of credit of $9,474 and $9,444 at December 31, 2024 and 2023, respectively. There was no outstanding debt under this line of credit at December 31, 2024 and 2023.

At December 31, 2024, the contractual future principal payments and principal payments of other borrowings assuming earliest call provisions are exercised, were as follows:

12. Stockholders' Equity

The Company has authority to issue 100,000 shares of no par value preferred stock.

No preferred shares were issued or outstanding as of December 31, 2024 or 2023.

The Company adopted the 2002 Stock Incentive Plan (the "SIP") to attract and retain employees and directors and provide incentives to such persons to promote the success and growth of the Company.

Options are granted at the current market price as determined in good faith by the Board of Directors, generally become exercisable at 20% or 33% of each anniversary date, generally fully vest over a period of three or five years and expire within a ten-year period. Restricted stock grants are for such consideration, or no consideration, as the Board may specify and may include requirements for future services or other restrictions. As of December 31, 2024 and 2023, there were 17,653 and 16,756 shares, respectively of unvested restricted stock grants, with $955 and $592 of expense, respectively remaining to vest.

The Company files a consolidated U.S. federal, a combined Wisconsin, and a unitary Illinois income tax return. The Company is no longer subject to U.S. federal or Illinois tax examinations by taxing authorities for years through 2020 and for Wisconsin state income taxes through 2019.

There were no unrecognized tax benefits as of December 31, 2024 and 2023.

The Company recognizes accrued interest and penalties related to unrecognized tax benefits in income tax expense. The Company's consolidated statement of financial position does not contain any interest and penalties related to uncertain tax positions as of December 31, 2024 and 2023, respectively.

14. Employee Benefits

The Bank has adopted a defined contribution qualified 401(k) profit-sharing plan covering substantially all employees. Participants may contribute up to 60% of pretax annual compensation, in accordance with Internal Revenue Service limits, and may also contribute amounts representing distributions from other qualified plans (rollover contributions). The Bank may make a matching contribution to the plan each year. Additional contributions to the 401(k) plan by the Bank are discretionary and are based on factors related to profits. Bank contributions were $1,034 and $930 in 2024 and 2023, respectively.

The Company has entered into deferred compensation arrangements with various directors and employees. The arrangements provide for the Company's directors and employees to elect to defer payment of compensation earned while serving as a director or employee. Certain deferrals are deemed invested in interest-bearing instruments, selected mutual funds, or Company stock until retirement or termination at which point deferrals are paid out over a time previously designated. Included in other liabilities is $1,280 and $1,375 of related deferred compensation as of December 31, 2024 and December 31, 2023, respectively. Expenses recognized as contributions under these arrangements totaled $0 in 2024 and 2023.

[**TABLE OF CONTENTS**](#TOC5)

The Bank implemented a non-qualified supplemental retirement plan (the "Plan") effective March, 2019 covering certain executive officers. The Plan is an unfunded plan for tax purposes and for purposes of Title I of the Employee Retirement Income Security Act of 1974 ("ERISA"), as may be applicable. The Plan is intended to be exempt in its entirety from Section 409A ("Section 409A") of the Internal Revenue Code of 1986 (the "Code"), and including in each case, their respective regulations, proposed regulations, and guidance. An award under the Plan shall be in the form of a payment by the Company directly to an insurance carrier to pay the premiums for a cash value life insurance policy on the Participant's life, fully owned by the Participant.

The Company had a non-qualified unfunded SERP covering specific executive officers. Benefits provided under the plan are based on years of service and the employee's final average pay, which is defined as the average salary and bonus for the highest three years within the five years preceding termination of employment. Included in other liabilities is $4,520 and $4,938 of related supplemental retirement plan as of December 31, 2024 and December 31, 2023, respectively. Expenses recognized as contributions under these arrangements totaled $204 and $143 in 2024 and 2023, respectively.

15. Commitments and Contingencies

In the normal course of business, the Company and the Bank are involved in various legal proceedings. In the opinion of management, any liability resulting from such proceedings would not have a material adverse effect on the consolidated financial statements.

The Bank is party to financial instruments with off-balance-sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit, financial guarantees, and standby letters of credit. They involve, to varying degrees, elements of credit and interest rate risk in excess of amounts recognized on the consolidated balance sheets.

The Bank's exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit and standby letters of credit is represented by the contractual notional amount of those instruments. The Bank uses the same credit policies in making commitments and issuing letters of credit as they do for on-balance-sheet instruments.

A summary of the contract or notional amount of the Bank's exposure to off-balance-sheet risk as of December 31, 2024 and 2023 is as follows:

---

| | | |
|:---|:---|:---|
| | **2024**  | **2023**  |
| Financial instruments whose contract amounts represent credit risk |  |  |
| Commitments to extend credit  | $224102 | $247824 |
| Credit card commitments  | $5652 | $6215 |
| Standby letters of credit  | $7175 | $6951 |

---

Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee.

Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. Standby letters of credit are conditional commitments issued to guarantee the performance of a customer to a third party. Those guarantees are primarily issued to support public and private borrowing arrangements. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers. The Bank evaluates each customer's credit worthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Bank upon extension of credit, is based on management's credit evaluation of the counterparty. Collateral held varies but may include accounts receivable, inventory, property and equipment, and income-producing commercial properties. Credit card commitments are unsecured.

17. Concentration of Credit Risk

Practically all of the Bank's loans, commitments, and commercial and standby letters of credit have been granted to customers in the Bank's market area. Although the Bank has a diversified loan portfolio, the ability of its debtors to honor their contracts is dependent on the economic conditions of the counties surrounding the Bank.

18. Derivative Instruments and Hedging Activities

The Bank's pipeline of locked residential mortgage loan commitments is considered a derivative. The Bank economically hedges its risk of changes in the fair value of locked residential mortgage loan commitments due to changes in interest rates through the use of forward sales contracts. Forward sales contracts require the Bank to deliver qualifying residential mortgage loans or pools of loans at a specified future date at a specified price or yield. Such forward sales contracts hedging the pipeline of located residential mortgage loan commitments are derivatives. The Bank has determined that the change in fair value of interest rate locks and forward sale commitments is immaterial. As such, no amounts have been recorded in the consolidated financial statements at December 31, 2024 and 2024.

19. Retained Earnings

The principal source of income and funds of the Company are dividends from the Bank. Dividends declared by the Bank that exceed the retained net income for the current year plus retained net income for the preceding two years must be approved by Federal and State regulatory agencies.

20. #### Regulatory Capital Requirements
Banks and bank holding companies are subject to regulatory capital requirements administered by federal banking agencies. Capital adequacy guidelines and, additionally for banks, prompt corrective action regulations, involve quantitative measures of assets, liabilities, and certain off balance sheet items calculated under regulatory accounting practices. Capital amounts and classifications are also subject to qualitative judgments by regulators. Failure to meet capital requirements can initiate regulatory action. The net unrealized gain or loss on available for sale securities is not included in computing regulatory capital. Management believes as of December 31, 2024, the Bank and Company meet all capital adequacy requirements to which they are subject.

Prompt corrective action regulations provide five classifications: well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized, and critically undercapitalized, although these terms are not used to represent overall financial condition. If adequately capitalized, regulatory approval is required to accept brokered deposits. If undercapitalized, capital distributions are limited, as is asset growth and expansion, and capital restoration plans are required. As of year-end 2024 and 2023, the most recent regulatory notifications categorized the bank as well capitalized under the regulatory framework for prompt corrective action. There are no conditions or events since that notification that management believes have changed the institution's category.

Section 1.04 <u>Effective Time; Closing</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (a) Subject to the terms and conditions of this Agreement, the Parties will make all such filings as may be required to consummate the Merger and the Bank Merger in accordance with applicable Laws. The Merger shall become effective as set forth in the articles of merger (the "***Articles of Merger***") related to the Merger, which will include the plan of merger (the "***Plan of Merger***"), that shall be filed with the WDFI-Corporations, as provided in the WBCL, on the Closing Date.

Section 1.06 <u>Reservation of Right to Revise Structure</u>.

BFC may at any time, without the approval of Centre, change the method of effecting the business combination contemplated by this Agreement if and to the extent that it reasonably deems such a change to be necessary; *provided*, *however*, that no such change shall (i) alter or change the amount of the consideration to be issued to the Holders as Merger Consideration, (ii) reasonably be expected to materially impede or delay consummation of the Merger, (iii) adversely affect the federal income tax treatment of the Holders in connection with the Merger or (iv) require submission to or approval of Centre's shareholders after the plan of merger set forth in this Agreement has been approved by Centre's shareholders. In the event BFC elects to make such a change, the Parties agree to cooperate to execute appropriate documents to reflect the change.

#### ARTICLE II

#### MERGER CONSIDERATION; EXCHANGE PROCEDURES
Section 2.01 <u>Merger Consideration</u>.

Subject to the provisions of this Agreement, at the Effective Time, automatically by virtue of the Merger and without any action on the part of the Parties or any shareholder of Centre:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (a) Each share of BFC Common Stock that is issued and outstanding immediately prior to the Effective Time shall remain issued and outstanding following the Effective Time and shall be unchanged by the Merger.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (b) Each share of Centre Common Stock (i) held as treasury stock or (ii) owned directly by BFC, Centre or any of their respective Subsidiaries (other than shares in trust accounts, managed accounts and the like for the benefit of employees or customers or otherwise held in fiduciary or agency capacity that are beneficially owned by third parties, or shares held as collateral for outstanding debt previously contracted) immediately prior to the Effective Time shall be cancelled and retired at the Effective Time without any conversion thereof, and no payment shall be made with respect thereto (the "***Centre Cancelled Shares***").

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (c) Notwithstanding anything in this Agreement to the contrary, all shares of Centre Common Stock that are issued and outstanding immediately prior to the Effective Time and which are held by a shareholder who did not vote in favor of the Merger (or consent thereto in writing) and who is entitled to demand and properly demands the fair value of such shares pursuant to, and who complies in all respects with, the provisions of Subchapter XIII of the WBCL, shall not be converted into or be exchangeable for the right to receive the Merger Consideration (the "***Dissenting Shares***"). The Holder of such Dissenting Shares (hereinafter called a "***Dissenting Shareholder***") instead shall be entitled to payment of the fair value of such shares in accordance with the applicable provisions of the WBCL (and at the Effective Time, such Dissenting Shares shall no longer be outstanding and shall automatically be cancelled and shall cease to exist and such Holder shall cease to have any rights with respect thereto, except the rights provided for pursuant to the applicable provisions of the WBCL and this <u>Section 2.01(c)</u>), unless and until such Dissenting Shareholder shall have failed to perfect such Holder's right to receive, or shall have effectively withdrawn or lost rights to demand or receive, the fair value of such shares of Centre Common Stock under the applicable provisions of the WBCL. If any Dissenting Shareholder shall fail to perfect or effectively withdraw or lose such Holder's dissenter's rights under the applicable provisions of the WBCL, each such Dissenting Share shall be deemed to have been converted into and to have become exchangeable for, the right to receive the Merger Consideration, without any interest thereon, in accordance with the applicable provisions of this Agreement. Centre shall give BFC (i) prompt notice of any written notices to exercise dissenters' rights in respect of any shares of Centre Common Stock, attempted withdrawals of such notices and any other instruments served pursuant to the WBCL and received by Centre relating to dissenters' rights and (ii) the opportunity to participate in negotiations and proceedings with respect to demands for fair value under the WBCL. Centre shall not, except with the prior written consent of BFC, voluntarily make any payment with respect to, or settle, or offer or agree to settle, any such demand for payment. Any portion of the Merger Consideration made available to the Exchange Agent pursuant to this <u>Article II</u> to pay for shares of Centre Common Stock for which dissenters' rights have been perfected shall be returned to BFC upon demand.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (d) Subject to <u>Section 2.05</u> regarding fractional shares, each share of Centre Common Stock (excluding Dissenting Shares and Centre Cancelled Shares) issued and outstanding at the Effective Time shall cease to be outstanding and shall be converted, in accordance with the terms of this <u>Article II</u>, into and exchanged for the right to receive 0.9200 shares (the "***Exchange Ratio***") of BFC Common Stock (the "***Merger Consideration***").

Section 2.02 <u>Adjustment of Merger Consideration for Tangible Book Value</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (a) If Centre Tangible Book Value (as defined and calculated below) as of the Closing Date is less than the Minimum Tangible Book Value, then the aggregate Merger Consideration will be reduced by an amount (the "***Capital Deficiency Amount***") equal to (A) the Minimum Tangible Book Value minus (B) Centre Tangible Book Value on the Closing Date, and the Exchange Ratio shall be adjusted to produce the aggregate Merger Consideration as reduced by such Capital Deficiency Amount.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (b) For purposes of this Agreement, "***Centre Tangible Book Value***" means the consolidated shareholders' equity of Centre and all of its Subsidiaries determined in accordance with GAAP consistently applied for past periods, excluding any effects of interest rate changes to Centre's securities portfolio, on a consolidated basis with First National Bank, whether upward or downward, from June 30, 2025; *provided, however*, that (i) the amount of any costs, fees, expenses and commissions payable to any broker, finder, financial advisor or investment banking firm in connection with this Agreement or the transactions contemplated hereby; (ii) the amount of all legal and accounting fees and other expenses incurred in connection with the negotiation, execution or performance of this Agreement or the consummation of the transactions contemplated hereby; (iii) the accrual of any costs, fees, expenses, contract payments, penalties or liquidated damages associated with or incurred in connection with the termination of Terminated Contracts (as defined in <u>Section 5.14</u>), including, but not limited to, the termination of any data processing contract following the Closing Date; (iv) amounts payable upon a change in control event under any Centre Material Contract; (v) the amount of any payments to be made pursuant to any existing employment, change in control, salary continuation, deferred compensation or other similar agreements or arrangements or severance, noncompetition, retention or bonus arrangements between Centre or First National Bank and any other Person, including the termination of such agreements, if the payment under such agreement or arrangement is triggered by the transactions set forth in this Agreement; (vi) the accrual of any future benefit payments due under any salary continuation, deferred compensation or other similar agreements through the date of final payment; and (vii) the amount of any additional accruals or costs (to the extent not already accrued) to fully fund and liquidate any Centre Benefit Plan (as defined herein) and to pay all related expenses and fees to the extent such termination is requested by BFC pursuant to <u>Section 5.11</u>, will not reduce or impact the calculation of Centre Tangible Book Value for purposes of this Section; *provided further,* that adjustments to the calculation of Centre Tangible Book Value with respect to (i)-(vii) shall be mutually determined by Centre and BFC in good faith. All such excluded amounts shall also be determined in accordance with GAAP, and capped by an amount equal to 125% of the total gross amount set forth in <u>Centre Disclosure Schedule 3.35</u>; *provided, however*, that data processing contract termination and de-conversion fees shall not be subject to such cap. For the avoidance of doubt, Centre Tangible Book Value shall be reduced dollar for dollar by the amount of any dividend or other distribution by Centre declared or paid on or after the date of this Agreement and prior to or on the Closing Date, as well as any payments made by Centre or First National Bank to service its outstanding debt and trust preferred securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (c) A calculation of Centre Tangible Book Value as of June 30, 2025, which assumes a Closing Date on or before January 1, 2026, including detailed adjustments as set forth in <u>Section 2.02(b)</u> is set forth in <u>Centre Disclosure Schedule 2.02(c)</u> (the "***Estimated Closing Statement***"). Within ten (10) Business Days of the end of each calendar month, Centre shall prepare a sample calculation of Centre Tangible Book Value as of the end of such calendar month (calculated in accordance with <u>Section 2.02(b)</u>) and provide such sample calculation to BFC for the Parties to discuss in good faith. As of a date that is not less than ten (10) Business Days prior to the intended Closing Date (the "***Calculation Date***"), Centre shall prepare in good faith and deliver to BFC an updated closing statement derived from the latest available financial information of Centre, adjusted for projections through the Closing Date and reflecting Centre Tangible Book Value as set forth in <u>Section 2.02(b)</u> (such statement, together with all

------

[**TABLE OF CONTENTS**](#TOC6)

backup schedules and information as may be requested by BFC, the "***Final Closing Statement***"). Such Final Closing Statement shall be prepared in a manner consistent with the Estimated Closing Statement. If BFC does not object in writing to the Final Closing Statement within five (5) Business Days after the date Centre submits such calculation to BFC, the Final Closing Statement shall be deemed to be accepted by BFC and shall constitute the final calculation of Centre Tangible Book Value at the Closing Date, subject only to any further changes mutually agreed upon by both Centre and BFC. If BFC timely objects in writing to the Final Closing Statement and the Parties are unable to resolve any dispute related to the calculations set forth in the Final Closing Statement within five (5) Business Days after the date Centre submits such calculation to BFC, then Centre and BFC shall submit the calculation of Centre Tangible Book Value at the Closing Date to an accounting firm independent from both BFC and Centre as shall be mutually agreed in writing by the Parties for review and resolution of any and all matters related to the calculation which remain in dispute. The independent accounting firm shall reach a final resolution of all matters (such determination of Centre Tangible Book Value by the independent accounting firm shall be consistent with and in accordance with <u>Section 2.02(b)</u>) and shall furnish such resolution in writing to Centre and BFC as soon as practicable, but in no event more than ten (10) Business Days after such matters have been referred to the independent accounting firm. Such resolution shall be made in accordance with this Agreement and will be conclusive and binding upon Centre and BFC, absent manifest error or fraud. The resolution reached by the Parties or the independent accounting firm in accordance with this <u>Section 2.02(c)</u> will constitute the final calculation of the Centre Tangible Book Value at the Closing Date. The costs for the independent accounting firm to reach such resolution shall be shared equally by Centre and BFC.

Section 2.03 <u>Centre Stock-Based Awards</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (a) At the Effective Time, each option to purchase Centre Common Stock granted under a Centre Stock Plan (a "***Centre Option***"), whether vested or unvested, which is outstanding immediately prior to the Effective Time shall fully vest (to the extent not vested) and be canceled, automatically and without any required action on the part of the holder thereof, and be converted into the right to receive an amount of cash equal to the product of (A) the excess, if any, of (1) the product of (x) the Exchange Ratio, *multiplied by* (y) the BFC Common Stock Price (the "***Per Share Cash Equivalent Consideration***"), *over* (2) the per share exercise price of the Centre Option prior to the Effective Time, *multiplied by* (B) the number of shares of Centre Common Stock subject to such Centre Option prior to the Effective Time, rounding up to the nearest cent. Any Centre Option with an exercise price that equals or exceeds the Per Share Cash Equivalent Consideration shall be canceled with no consideration being paid to the option holder with respect to such Centre Option. All amounts payable pursuant to this <u>Section 2.03(a)</u> to the holders of Centre Options shall be paid as soon as practicable after, and in any event within five (5) Business Days following, the Effective Time, without interest and shall be less applicable tax withholdings.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (d) At the Effective Time, the Centre Stock Plans, the Centre Stock Awards and all related grant agreements thereunder shall terminate and the provisions in any other plan, program or arrangement providing for the issuance or grant of any other interest in respect of the capital stock of Centre shall be of no further force and effect.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (e) Prior to the Effective Time, Centre, the board of directors of Centre and the compensation committee of the board of directors of Centre, as applicable, shall adopt any resolutions and take any actions that are necessary to effectuate the treatment of the Centre Stock Awards pursuant to this <u>Section 2.03</u>. Centre shall take all actions necessary to ensure that, from and after the Effective Time, neither BFC nor any of its Subsidiaries will be required to deliver shares of BFC Common Stock or other capital stock of Centre to any person pursuant to or in settlement of the Centre Stock Awards.

Section 2.04 <u>Rights as Shareholders; Stock Transfers</u>.

At the Effective Time, all shares of Centre Common Stock, when converted in accordance with <u>Section 2.01(d)</u>, shall no longer be outstanding and shall automatically be cancelled and retired and shall cease to exist, and each Certificate or Book-Entry Share previously evidencing such shares shall thereafter represent only the right to receive for each such share of Centre Common Stock, the Merger Consideration and any cash in lieu of fractional shares of BFC Common Stock in accordance with this <u>Article II</u>. At the Effective Time, Holders of Centre Common Stock shall cease to be, and shall have no rights as, shareholders of Centre, other than the right to receive the Merger Consideration and cash in lieu of fractional shares of BFC Common Stock as provided under this <u>Article II</u>. At the Effective Time, the stock transfer books of Centre shall be closed, and there shall be no registration of transfers on the stock transfer books of Centre of shares of Centre Common Stock.

Section 2.05 <u>Fractional Shares</u>.

Notwithstanding any other provision hereof, no fractional shares of BFC Common Stock and no certificates or scrip therefor, or other evidence of ownership thereof, will be issued in the Merger. In lieu thereof, BFC shall pay or cause to be paid to each Holder who would otherwise receive a fractional share of BFC Common Stock, rounded to the nearest one hundredth of a share, an amount of cash (without interest and rounded to the nearest whole cent) determined by multiplying the fractional share interest in BFC Common Stock to which such Holder would otherwise be entitled by the BFC Common Stock Price.

Section 2.06 <u>Plan of Reorganization</u>.

It is intended that the Merger and the Bank Merger shall each qualify as a "reorganization" within the meaning of Section 368(a) of the Code, and that this Agreement shall constitute a "plan of reorganization" as that term is used in Sections 354 and 361 of the Code.

Section 2.07 <u>Exchange Procedures</u>.

BFC shall cause as promptly as practicable after the Effective Time, but in no event later than five (5) Business Days after the Closing Date, the Exchange Agent to commence mailing and delivery to each Holder appropriate and customary transmittal materials, which shall specify that delivery shall be effected, and risk of loss and title to the Certificates or Book-Entry Shares shall pass, only upon delivery of the Certificates or Book-Entry Shares to the Exchange Agent, as well as instructions for use in effecting the surrender of the Certificates or Book-Entry Shares in exchange for the Merger Consideration (including cash in lieu of fractional shares) as provided for in this Agreement (the "***Letter of Transmittal***").

Section 2.08 <u>Deposit and Delivery of Merger Consideration</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (a) Prior to the Effective Time, BFC shall (i) deposit, or shall cause to be deposited, with the Exchange Agent stock certificates representing the number of shares of BFC Common Stock (or otherwise issue an instruction letter regarding the issuance of the Merger Consideration in book entry to Holders) and cash sufficient to deliver the Merger Consideration (together with, to the extent then determinable, any cash payable in lieu of fractional shares pursuant to <u>Section 2.05</u>, and if applicable, cash in an aggregate amount sufficient to make the appropriate payment to the Holders of Dissenting Shares) (collectively, the "***Exchange Fund***"), and (ii) instruct the Exchange Agent to pay such Merger Consideration and cash in lieu of fractional shares in accordance with this Agreement as promptly as

------

[**TABLE OF CONTENTS**](#TOC6)

practicable after the Effective Time and conditioned upon receipt of a properly completed Letter of Transmittal. The Exchange Agent and BFC, as the case may be, shall not be obligated to deliver the Merger Consideration to a Holder that such Holder would otherwise be entitled as a result of the Merger until such Holder surrenders the Certificates or Book-Entry Shares representing the shares of Centre Common Stock for exchange as provided in this <u>Article II</u>, or, an appropriate affidavit of loss and indemnity agreement and/or a bond in such amount as may be reasonably required in each case by BFC or the Exchange Agent.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (b) Any portion of the Exchange Fund that remains unclaimed by the shareholders of Centre for one (1) year after the Effective Time (as well as any interest or proceeds from any investment thereof) shall be delivered by the Exchange Agent to BFC. Any shareholders of Centre who have not theretofore complied with this <u>Section 2.08</u> shall thereafter look only to BFC for the Merger Consideration, any cash in lieu of fractional shares of Centre Common Stock to be issued or paid in consideration therefor, and any dividends or distributions to which such Holder is entitled in respect of each share of Centre Common Stock such shareholder held immediately prior to the Effective Time, as determined pursuant to this Agreement, in each case without any interest thereon. If outstanding Certificates or Book-Entry Shares for shares of Centre Common Stock are not surrendered or the payment for them is not claimed prior to the date on which such shares of BFC Common Stock or cash would otherwise escheat to or become the property of any governmental unit or agency, the unclaimed items shall, to the extent permitted by the Law of abandoned property and any other applicable Law, become the property of BFC (and to the extent not in its possession shall be delivered to it), free and clear of all claims or interest of any Person previously entitled to such property. Neither the Exchange Agent nor any Party shall be liable to any Holder represented by any Certificate or Book-Entry Share for any amounts delivered to a public official pursuant to applicable abandoned property, escheat or similar Laws. BFC and the Exchange Agent shall be entitled to rely upon the stock transfer books of Centre to establish the identity of those Persons entitled to receive the Merger Consideration specified in this Agreement, which books shall be conclusive with respect thereto. In the event of a dispute with respect to ownership of any shares of Centre Common Stock represented by any Certificate or Book-Entry Share, BFC and the Exchange Agent shall be entitled to tender to the custody of any court of competent jurisdiction any Merger Consideration represented by such Certificate or Book-Entry Share and file legal proceedings interpleading all parties to such dispute, and will thereafter be relieved with respect to any claims thereto.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (c) BFC or the Exchange Agent, as applicable, shall be entitled to deduct and withhold from any amounts otherwise payable pursuant to this Agreement to any Holder such amounts as BFC is required to deduct and withhold under applicable Law. Any amounts so deducted and withheld shall be remitted to the appropriate Governmental Authority and upon such remittance shall be treated for all purposes of this Agreement as having been paid to the Holder in respect of which such deduction and withholding was made by BFC or the Exchange Agent, as applicable.

Section 2.09 <u>Rights of Certificate Holders after the Effective Time</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (a) All shares of BFC Common Stock to be issued pursuant to the Merger shall be deemed issued and outstanding as of the Effective Time and if ever a dividend or other distribution is declared by BFC in respect of the BFC Common Stock, the record date for which is at or after the Effective Time, that declaration shall include dividends or other distributions in respect of all shares of BFC Common Stock issuable pursuant to this Agreement. No dividends or other distributions in respect of the BFC Common Stock shall be paid to any Holder of any unsurrendered Certificate or Book-Entry Share until such Certificate or Book-Entry Share is surrendered for exchange in accordance with this <u>Article II</u>. Subject to the effect of applicable Laws, following surrender of any such Certificate or Book-Entry Share, there shall be issued and/or paid to the Holder of the Certificates representing whole shares of BFC Common Stock issued in exchange therefor, without interest, (i) at the time of such surrender, the dividends or other distributions with a record date after the Effective Time theretofore payable with respect to such whole shares of BFC Common Stock and not paid and (ii) at the appropriate payment date, the dividends or other distributions payable with respect to such whole shares of BFC Common Stock with a record date after the Effective Time but with a payment date subsequent to surrender. For the avoidance of doubt, Holders shall not have any right to participate in any dividends or

------

[**TABLE OF CONTENTS**](#TOC6)

other distributions declared by BFC in respect of the BFC Common Stock if the record date of such dividend or distribution is prior to the Effective Time.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (b) In the event of a transfer of ownership of a Certificate representing Centre Common Stock that is not registered in the stock transfer records of Centre, the proper amount of cash and/or shares of BFC Common Stock shall be paid or issued in exchange therefor to a person other than the person in whose name the Certificate so surrendered is registered if the Certificate formerly representing such Centre Common Stock shall be properly endorsed or otherwise be in proper form for transfer and the person requesting such payment or issuance shall pay any transfer or other similar Taxes required by reason of the payment or issuance to a person other than the registered Holder of the Certificate or establish to the satisfaction of BFC that the Tax has been paid or is not applicable.

Section 2.10 <u>Anti-Dilution Provisions</u>.

If the number of shares of BFC Common Stock or Centre Common Stock issued and outstanding prior to the Effective Time shall be increased or decreased, or changed into or exchanged for a different number or kind of shares or securities, in any such case as a result of a stock split, reverse stock split, stock combination, stock dividend, reclassification, or similar transaction, or there shall be any extraordinary dividend or distribution with respect to such stock, and the record date therefor shall be prior to the Effective Time, an appropriate and proportionate adjustment shall be made to the Merger Consideration to give Holders of Centre Common Stock the same economic effect as contemplated by this Agreement prior to such event. For the avoidance of doubt, no adjustment shall be made with regard to BFC Common Stock if (i) BFC issues additional shares of BFC Common Stock and receives consideration for such shares (including, without limitation, upon the exercise of outstanding stock options or other equity awards) or (ii) BFC issues employee or director stock grants or similar equity awards pursuant to a BFC benefit plan.

It is understood that BFC shall assume primary responsibility for the preparation of joint press releases relating to this Agreement, the Merger and the other transactions contemplated hereby.

Section 5.08 <u>Access; Current Information</u>.

BFC shall coordinate any such access in accordance with this <u>Section 5.08(a)</u> with Centre's President, Donald A. O'Day.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (b) For the purposes of verifying the representations and warranties of the other and preparing for the Merger and the other matters contemplated by this Agreement, during the period of time from the date of this Agreement to the Effective Time, upon reasonable notice and subject to applicable Laws, BFC agrees to furnish to Centre such information as Centre may reasonably request concerning the

business of BFC and its Subsidiaries that is substantially similar in scope to the information provided to Centre in connection with its diligence review prior to the date of this Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (c) As promptly as reasonably practicable after they become available, Centre will furnish to BFC copies of the board packages distributed to the board of directors of Centre or any of its Subsidiaries, and minutes from the meetings thereof, copies of any internal management financial control reports showing actual financial performance against plan and previous period, and copies of any reports provided to the board of directors of Centre or any committee thereof relating to the financial performance and risk management of Centre.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (d) During the period from the date of this Agreement to the Effective Time, at the reasonable request of either Party, the other Party will cause one or more of its designated representatives to confer with representatives of the requesting Party and to report the general status of the ongoing operations of the other Party and its Subsidiaries. Without limiting the foregoing, Centre agrees to provide to BFC (i) a copy of each report filed by Centre or any of its Subsidiaries with a Governmental Authority, (ii) a copy of Centre's monthly loan trial balance and (iii) a copy of Centre's monthly statement of condition and profit and loss statement and, if requested by BFC, a copy of Centre's daily statement of condition and daily profit and loss statement, in each case, which shall be provided as promptly as reasonably practicable after it is filed or prepared, as applicable. Centre further agrees to provide BFC, no later than ten (10) Business Days following the end of each calendar month following the date hereof, any supplements to <u>Centre Disclosure Schedule 3.19</u>, <u>Centre Disclosure Schedule 3.22(a)</u> and <u>Centre Disclosure Schedule 3.22(b)</u> that would be required if the references to June 30, 2025 in each corresponding representation and warranty of Centre were changed to the date of the most recently ended calendar month.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (e) No investigation by a Party or its representatives shall be deemed to modify or waive any representation, warranty, covenant or agreement of the other Party set forth in this Agreement, or the conditions to the respective obligations of BFC and Centre to consummate the transactions contemplated hereby.

In the event any of the restrictions in this <u>Section 5.08(f)</u> shall apply, such Party shall use its commercially reasonable efforts to provide appropriate consents, waivers, decrees and approvals necessary to satisfy any confidentiality issues relating to documents prepared or held by third parties (including work papers), and the Parties will make appropriate alternate disclosure arrangements, including adopting additional specific procedures to protect the confidentiality of sensitive material and to ensure compliance with applicable Laws.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (a) Except as permitted by <u>Section 5.09(b)</u>, Centre shall not, and shall cause its Subsidiaries and each of their respective officers, directors and employees not to, and will not authorize any investment bankers, financial advisors, attorneys, accountants, consultants, affiliates or other agents of Centre or any of Centre's Subsidiaries (collectively, the "***Centre Representatives***") to, directly or indirectly, (i) initiate, solicit, induce or knowingly encourage, or take any action to facilitate the making of, any inquiry, offer or proposal which constitutes, or could reasonably be expected to lead to, an Acquisition Proposal; (ii) participate in any discussions or negotiations regarding any Acquisition Proposal or furnish, or otherwise afford access, to any Person (other than BFC) any information or data with respect to Centre or any of its Subsidiaries or otherwise relating to an Acquisition Proposal; (iii) release any Person from, waive any provisions of, or fail to enforce any confidentiality agreement or standstill agreement to which Centre is a party; or (iv) enter into any agreement, confidentiality agreement, agreement in principle or letter of intent with respect to any Acquisition Proposal or approve or resolve to approve any Acquisition Proposal or any agreement, agreement in principle or letter of intent

relating to an Acquisition Proposal. Any violation of the foregoing restrictions by any of the Centre Representatives, whether or not such Centre Representative is so authorized and whether or not such Centre Representative is purporting to act on behalf of Centre or otherwise, shall be deemed to be a breach of this Agreement by Centre. Centre and its Subsidiaries shall, and shall cause each of the Centre Representatives to, immediately cease and cause to be terminated any and all existing discussions, negotiations, and communications with any Persons with respect to any existing or potential Acquisition Proposal.

For purposes of this Agreement, "***Acquisition Proposal***" means any inquiry, offer or proposal (other than an inquiry, offer or proposal from BFC), whether or not in writing, contemplating, relating to, or that could reasonably be expected to lead to, an Acquisition Transaction.

For purposes of this Agreement, "***Acquisition Transaction***" means (A) any transaction or series of transactions involving any merger, consolidation, recapitalization, share exchange, liquidation, dissolution or similar transaction involving Centre or any of its Subsidiaries; (B) any transaction pursuant to which any third party or group acquires or would acquire (whether through sale, lease or other disposition), directly or indirectly, the assets of Centre or any of its Subsidiaries constituting, in the aggregate, 20% or more of the fair value of the consolidated assets of Centre; (C) any issuance, sale or other disposition of (including by way of merger, consolidation, share exchange or any similar transaction) securities (or options, rights or warrants to purchase or securities convertible into, such securities) representing 20% or more of the votes attached to the outstanding securities of Centre or any of its Subsidiaries; (D) any tender offer or exchange offer that, if consummated, would result in any third party or group beneficially owning 20% or more of any class of equity securities of Centre or any of its Subsidiaries; or (E) any transaction which is similar in form, substance or purpose to any of the foregoing transactions, or any combination of the foregoing.

For purposes of this Agreement, "***Superior Proposal***" means a bona fide, unsolicited Acquisition Proposal (i) that if consummated would result in a third party (or in the case of a direct merger between such third party and Centre or any of its Subsidiaries, the shareholders of such third party) acquiring, directly or indirectly, more than 50% of the outstanding Centre Common Stock or more than 50% of the assets of Centre and its Subsidiaries (measured as a percentage of the fair value of the consolidated assets of Centre), taken as a whole, for consideration consisting of cash and/or securities and (ii) that the board of directors of Centre reasonably determines in good faith, after consultation with its outside financial advisor and outside legal counsel, (A) is reasonably capable of being completed, taking into account all financial, legal, regulatory and other aspects of such proposal, including all conditions contained therein and the Person making such Acquisition Proposal, and (B) taking into account any changes to this Agreement proposed by BFC in response to such Acquisition Proposal, as contemplated by <u>Section 5.09(c)</u>, and all financial, legal, regulatory and other aspects of such takeover proposal, including all conditions contained therein and the Person making such proposal, is more favorable to the shareholders of Centre from a financial point of view than the Merger.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (b) Notwithstanding <u>Section 5.09(a)</u> or any other provision of this Agreement, prior to the date of the Centre Meeting, Centre may take any of the actions described in <u>Section 5.09(a)</u> if, but only if, (i) Centre has received a bona fide unsolicited written Acquisition Proposal that did not result from a breach of <u>Section 5.09(a)</u>; (ii) the board of directors of Centre reasonably determines in good faith, after consultation with and having considered the advice of its outside financial advisor and outside legal counsel, that (A) such Acquisition Proposal constitutes or is reasonably likely to lead to a Superior Proposal and (B) the failure to take such actions would cause it to violate its fiduciary duties to Centre's shareholders under applicable Law; (iii) Centre has provided BFC with at least three (3) Business Days' prior notice of such determination; and (iv) prior to furnishing or affording access to any information or data with respect to Centre or any of its Subsidiaries or otherwise relating to an Acquisition Proposal, Centre receives from such Person a confidentiality agreement with terms no less favorable to Centre than those contained in the confidentiality agreement with BFC. Centre shall promptly provide to BFC any non-public information regarding Centre or its Subsidiaries provided to any other Person which was not previously provided to BFC, such additional information to be provided no later than the date of provision of such information to such other party.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (c) Centre shall promptly (and in any event within twenty-four (24) hours) notify BFC in writing if any proposals or offers are received by, any information is requested from, or any negotiations or discussions are sought to be initiated or continued with, Centre or the Centre Representatives, in each case in connection with any Acquisition Proposal, and such notice shall indicate the name of the Person initiating such discussions or negotiations or making such proposal, offer or information request and the material terms and conditions of any proposals or offers (and, in the case of written materials relating to such proposal, offer, information request, negotiations or discussion, providing copies of such materials (including e-mails or other electronic communications) except to the extent that such materials constitute confidential information of the party making such offer or proposal under an effective confidentiality agreement). Centre agrees that it shall keep BFC informed, on a reasonably current basis, of the status and terms of any such proposal, offer, information request, negotiations or discussions (including any amendments or modifications to such proposal, offer or request).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (d) Except as set forth in <u>Section 5.09(e)</u>, neither the board of directors of Centre nor any committee thereof shall (i) withdraw, qualify, amend or modify, or propose to withdraw, qualify, amend or modify, in a manner adverse to BFC in connection with the transactions contemplated by this Agreement (including the Merger), the Centre Recommendation; (ii) fail to reaffirm the Centre Recommendation within three (3) Business Days following a request by BFC, or make any statement, filing or release, in connection with the Centre Meeting or otherwise, inconsistent with the Centre Recommendation (it being understood that taking a neutral position or no position with respect to an Acquisition Proposal shall be considered an adverse modification of the Centre Recommendation); (iii) approve or recommend, or propose to approve or recommend, any Acquisition Proposal; or (iv) enter into (or cause Centre or any of its Subsidiaries to enter into) any letter of intent, agreement in principle, acquisition agreement or other agreement (A) related to any Acquisition Transaction (other than a confidentiality agreement entered into in accordance with the provisions of <u>Section 5.09(b)</u>) or (B) requiring Centre to abandon, terminate or fail to consummate the Merger or any other transaction contemplated by this Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (e) Notwithstanding <u>Section 5.09(d)</u>, prior to the date of the Centre Meeting, the board of directors of Centre may withdraw, qualify, amend or modify the Centre Recommendation (a "***Centre Subsequent Determination***"), or terminate this Agreement in order to concurrently enter into an Agreement with respect to a Superior Proposal, after the fifth (5<sup>th</sup>) Business Day following BFC's receipt of a notice (the "***Notice of Superior Proposal***") from Centre advising BFC that the board of directors of Centre has decided (in good faith after consultation with its outside legal counsel and financial advisor) that a bona fide unsolicited written Acquisition Proposal that it received (that did not result from a breach of <u>Section 5.09(a)</u>) constitutes a Superior Proposal if, but only if, (i) the board of directors of Centre has determined in good faith, after consultation with and having considered the advice of outside legal counsel and its financial advisor, that the failure to take such actions would cause it to violate its fiduciary duties to Centre's shareholders under applicable Law, (ii) during the five (5) Business Day period after receipt of the Notice of Superior Proposal by BFC (the "***Notice Period***"), Centre and the board of directors of Centre shall have cooperated and negotiated in good faith with BFC to make such adjustments, modifications or amendments to the terms and conditions of this Agreement as would enable Centre to proceed with the Centre Recommendation without a Centre Subsequent Determination; *provided*, *however*, that BFC shall not have any obligation to propose any adjustments, modifications or amendments to the terms and conditions of this Agreement and (iii) at the end of the Notice Period, after taking into account any such adjusted, modified or amended terms as may have been proposed by BFC since its receipt of such Notice of Superior Proposal, the board of directors of Centre has again in good faith made the determination (A) in clause (i) of this <u>Section 5.09(e)</u> and (B) that such Acquisition Proposal constitutes a Superior Proposal. In the event of any material revisions to the Superior Proposal, Centre shall be required to deliver a new Notice of Superior Proposal to BFC and again comply with the requirements of this <u>Section 5.09(e)</u>, except that the Notice Period shall be reduced to three (3) Business Days.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (f) Nothing contained in this <u>Section 5.09</u> shall prohibit Centre or the board of directors of Centre from complying with Centre's obligations required under Rule 14e-2(a) promulgated under the Exchange Act; *provided*, *however*, that any such disclosure relating to an Acquisition Proposal (other than a "stop, look and listen" or similar communication of the type contemplated by Rule 14d-9(f) under

------

[**TABLE OF CONTENTS**](#TOC8)

the Exchange Act) shall be deemed a change in the Centre Recommendation unless the board of directors of Centre reaffirms the Centre Recommendation in such disclosure.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (g) Notwithstanding any Centre Subsequent Determination, this Agreement shall be submitted to Centre's shareholders at the Centre Meeting for the purpose of voting on the approval of this Agreement and the transactions contemplated hereby (including the Merger) and nothing contained herein shall be deemed to relieve Centre of such obligation; *provided*, *however*, that if the board of directors of Centre shall have made a Centre Subsequent Determination with respect to a Superior Proposal and this Agreement has been terminated pursuant to <u>Section 7.01(f)</u> or <u>Section 7.01(g)</u>, then the board of directors of Centre may recommend approval of such Superior Proposal by the shareholders of Centre.

Section 5.10 <u>Indemnification</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (a) For a period of six (6) years from and after the Effective Time, and in any event subject to the provisions of <u>Section 5.10(b)</u>, BFC shall indemnify and hold harmless the present and former directors and officers of Centre and its Subsidiaries (each an "***Indemnified Party***"), against all costs, expenses (including reasonable attorney's fees), judgments, fines, losses, claims, damages or liabilities or amounts that are paid in settlement (which settlement shall require the prior written consent of BFC, which consent shall not be unreasonably withheld) of or in connection with any claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative (each a "***Claim***"), arising out of actions or omissions of such persons in the course of performing their duties for Centre or any of its Subsidiaries occurring at or before the Effective Time (including the Merger and the other transactions contemplated hereby), regardless of whether such Claim is asserted or claimed before, or after, the Effective Time, to the same extent permitted under the organizational documents of Centre and its Subsidiaries in effect on the date of this Agreement to the extent permitted by applicable Law; *provided, however*, that notwithstanding anything to the contrary contained in the organizational documents of Centre or its Subsidiaries, BFC shall have no obligation to provide indemnification under this paragraph (a) to any Indemnified Party for any Excluded Claim.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (b) Any Indemnified Party wishing to claim indemnification under this <u>Section 5.10</u> shall promptly notify BFC upon learning of any Claim, *provided that*, failure to so notify shall not affect the obligation of BFC under this <u>Section 5.10</u>, unless, and only to the extent that, BFC is materially prejudiced in the defense of such Claim as a consequence. In the event of any such Claim (whether asserted or claimed prior to, at or after the Effective Time), (i) BFC shall have the right to assume the defense thereof and BFC shall not be liable to such Indemnified Parties for any legal expenses or other counsel or any other expenses subsequently incurred by such Indemnified Parties in connection with the defense thereof, except that if BFC elects not to assume such defense or counsel for the Indemnified Party reasonably advised the Indemnified Party that there are material issues that raise conflicts of interest between BFC and the Indemnified Party, the Indemnified Party may retain counsel reasonably satisfactory to it, and BFC shall pay the reasonable fees and expenses of such counsel for the Indemnified Party, (ii) the Indemnified Parties will cooperate in the defense of any such matter, (iii) BFC shall not be liable for any settlement effected without its prior written consent and (iv) BFC shall have no obligation hereunder to any Indemnified Party if such indemnification would be in violation of any applicable federal or state banking Laws or regulations, or in the event that a federal or state banking agency or a court of competent jurisdiction shall determine that indemnification of an Indemnified Party in the manner contemplated hereby is prohibited by applicable Laws and regulations, whether or not related to banking Laws.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (c) For a period of six (6) years following the Effective Time, BFC will maintain director's and officer's liability insurance (herein, "***D&O Insurance***") that serves to reimburse the present and former officers and directors of Centre or its Subsidiaries (determined as of the Effective Time) with respect to claims against such directors and officers arising from facts or events occurring before the Effective Time (including the transactions contemplated hereby), which insurance will contain at least the same coverage and amounts, and contain terms and conditions no less advantageous to the Indemnified Party, as that coverage currently provided by Centre; *provided that*, if BFC is unable to maintain or obtain the insurance called for by this <u>Section 5.10</u>, BFC shall use its commercially reasonable efforts to provide as much comparable insurance as is reasonably available (subject to the limitations described below in

------

[**TABLE OF CONTENTS**](#TOC8)

this Section 5.10(c)); and *provided*, *further,* that officers and directors of Centre or its Subsidiaries may be required to make application and provide customary representations and warranties to the carrier of the D&O Insurance for the purpose of obtaining such insurance. In no event shall BFC be required to expend for such tail insurance a premium amount in excess of an amount equal to 100% of the annual premiums paid by Centre for D&O Insurance in effect as of the date of this Agreement (the "***Maximum D&O Tail Premium***"). If the cost of such tail insurance exceeds the Maximum D&O Tail Premium, BFC shall obtain tail insurance coverage or a separate tail insurance policy with the greatest coverage available for a cost not exceeding the Maximum D&O Tail Premium.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (d) Any indemnification payments made pursuant to this <u>Section 5.10</u> are subject to and conditioned upon their compliance with Section 18(k) of the Federal Deposit Insurance Act (12 U.S.C. § 1828(k)) and the regulations promulgated by the FDIC (12 C.F.R. Part 359).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (e) This <u>Section 5.10</u> shall survive the Effective Time, is intended to benefit each Centre Indemnified Party (each of whom shall be entitled to enforce this Section against BFC), and shall be binding on all successors and assigns of BFC.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (f) If BFC or any of its successors and assigns (i) shall consolidate with or merge into any other corporation or entity and shall not be the continuing or surviving corporation or entity of such consolidation or merger, or (ii) shall transfer all or substantially all of its property and assets to any individual, corporation or other entity, then, in each such case, proper provision shall be made so that the successors and assigns of BFC and its Subsidiaries shall assume the obligations set forth in this <u>Section 5.10</u>.

Section 5.11 <u>Employees; Benefit Plans</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (a) Following the Effective Time, with respect to each Covered Employee (as defined below), for the period ending on the earlier of (i) the six (6) month anniversary of the Effective Time or (ii) the last day that such Covered Employee is employed by BFC or one of its Affiliates, BFC shall maintain or cause to be maintained employee benefit plans for the benefit of employees who are full time employees of Centre on the Closing Date and who become full-time employees of BFC ("***Covered Employees***") that provide employee benefits which, in the aggregate, are substantially comparable to the employee benefits and cash-based compensation opportunities that are made available on a uniform and non-discriminatory basis to similarly situated employees of BFC; *provided*, *however*, that in no event shall any Covered Employee be eligible to participate in any closed or frozen plan of BFC. BFC shall give the Covered Employees credit for their prior service with Centre for purposes of eligibility (including initial participation and eligibility for current benefits) and vesting under any employee benefit plan maintained by BFC and in which Covered Employees may be eligible to participate.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (b) With respect to any employee benefit plan of BFC that is a health, dental, vision or other welfare plan in which any Covered Employee is eligible to participate, for the plan year that includes the Closing, if Covered Employees are eligible to participate in such plans, BFC shall use commercially reasonable efforts to cause any pre-existing condition limitations, eligibility waiting periods or evidence of insurability requirements under such BFC plan to be waived with respect to such Covered Employee and his or her covered dependents to the extent such condition was or would have been covered under the Centre Benefit Plan in which such Covered Employee participated immediately prior to the Effective Time.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (c) Following the Effective Time, Bank First shall credit each Covered Employee with an amount of paid time off equal to such Covered Employee's accrued but unused paid time off at First National Bank ("***Carryover PTO***"), provided that, to the extent permitted by applicable Law, (i) Bank First may allocate the Carryover PTO and between vacation leave and sick leave in its discretion, and (ii) Carryover PTO shall be limited to eighty (80) hours per year for hourly employees, and salaries employees will not be allowed any Carryover PTO.

Centre shall provide BFC with evidence that the Centre 401(k) Plan has been terminated and provide copies of the appropriate

The accounts of all participants and beneficiaries in the Centre 401(k) Plan shall become fully vested upon termination of such plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (e) Prior to the Effective Time, Centre shall take, and shall cause its Subsidiaries to take, all actions requested by BFC that may be necessary or appropriate to, conditioned on the occurrence of the Effective Time, (i) cause one or more Centre Benefits Plans not covered above to terminate as of the Effective Time, or as of the date immediately preceding the Effective Time, (ii) cause benefit accruals and entitlements under any Centre Benefit Plan to cease as of the Effective Time, or as of the date immediately preceding the Effective Time, (iii) cause the continuation on and after the Effective Time of any contract, arrangement or insurance policy relating to any Centre Benefit Plan for such period as may be requested by BFC, or (iv) facilitate the merger of any Centre Benefit Plan into any employee benefit plan maintained by BFC. All resolutions, notices, or other documents issued, adopted or executed in connection with the implementation of this <u>Section 5.11(e)</u> shall be subject to BFC's reasonable prior review and approval, which shall not be unreasonably withheld, conditioned or delayed.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (f) Except for any employee listed on <u>Centre Disclosure Schedule 5.11(f)</u>, any employee of Centre or First National Bank that does not become an employee of Bank First at the Effective Time (other than for cause, death, disability, normal retirement or voluntarily resignation) shall receive a severance payment calculated in accordance with the policy set forth in <u>BFC Disclosure Schedule 5.11(f)</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (g) BFC will establish a retention bonus pool, in an amount to be determined in the sole discretion of BFC, in order to encourage certain Centre employees to remain employed with BFC, thereby assisting BFC with continuity planning following the announcement and consummation of the transactions contemplated by this Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (h) Following the Effective Time, BFC shall assume, honor and comply with all obligations set forth in the employment and change in control agreements listed on <u>Centre Disclosure Schedule 3.15(h)</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (i) Nothing in this <u>Section 5.11</u> shall be construed to limit the right of BFC (including, following the Closing Date, Centre) to amend or terminate any Centre Benefit Plan or other employee benefit plan, to the extent such amendment or termination is permitted by the terms of the applicable plan, nor shall anything in this <u>Section 5.11</u> be construed to require BFC (including, following the Closing Date, Centre) to retain the employment of any particular Covered Employee for any fixed period of time following the Closing Date, and the continued retention (or termination) by BFC of any Covered Employee subsequent to the Effective Time shall be subject in all events to BFC's normal and customary employment procedures and practices, including customary background screening and evaluation procedures and satisfactory employment performance.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (j) For purposes of this <u>Section 5.11</u>, (i) "employees of Centre" shall include employees of Centre or any of its Subsidiaries, (ii) "employees of BFC" shall include employees of BFC or any of its Subsidiaries, (iii) all references to Centre shall include each of the Subsidiaries of Centre (iv) all references to BFC shall include each of the Subsidiaries of BFC.

Section 5.12 <u>Notification of Certain Changes</u>.

BFC and Centre shall promptly advise the other Party of any change or event having, or which could reasonably be expected to have, a Material Adverse Effect or which it believes would, or which could reasonably be expected to, cause or constitute a material breach of any of its or its respective Subsidiaries' representations, warranties or covenants contained herein and Centre shall provide on a periodic basis written notice to BFC of any matters that Centre becomes aware of that should be disclosed on a supplement or amendment to the Centre Disclosure Schedule; *provided*, that any failure to give notice in accordance with the foregoing shall not be deemed to constitute a violation of this <u>Section 5.12</u> or the failure of any condition

This Agreement represents the entire understanding of the Parties and thereto with reference to the transactions contemplated hereby, and this Agreement supersedes any and all other oral or written agreements heretofore made. Except for the Indemnified Parties' rights under <u>Section 5.10</u>, BFC and Centre hereby agree that their respective representations, warranties and covenants set forth herein are solely for the benefit of the other Party, in accordance with and subject to the terms of this Agreement, and this Agreement is not intended to, and does not, confer upon any Person (including any person or employees who might be affected by <u>Section 5.11</u>), other than the Parties, any rights or remedies hereunder, including, the right to rely upon the representations and warranties set forth herein. The representations and warranties in this Agreement are the product of negotiations between the Parties and are for the sole benefit of the Parties. Consequently, Persons other than the Parties may not rely upon the representations and warranties in this Agreement as characterizations of actual facts or circumstances as of the date of this Agreement or as of any other date.

Section 9.07 <u>Severability</u>.

In the event that any one or more provisions of this Agreement shall for any reason be held invalid, illegal or unenforceable in any respect, by any court of competent jurisdiction, such invalidity, illegality or unenforceability shall not affect any other provisions of this Agreement and the Parties will use their commercially reasonable efforts to substitute a valid, legal and enforceable provision which, insofar as practical, implements the purposes and intents of this Agreement.

[**TABLE OF CONTENTS**](#TOC9)

Section 9.08 <u>Enforcement of the Agreement</u>.

The Parties agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the Parties shall be entitled to seek an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof in any court of the United States or any state having jurisdiction without having to show or prove economic damages and without the requirement of posting a bond, this being in addition to any other remedy to which they are entitled at law or in equity. Moreover, in addition to any other remedy that BFC is entitled to under this Agreement, at law or in equity, to the extent there is a material breach by Centre with respect to any of its representations, warranties or covenants as set forth in this Agreement, BFC shall have the right, in its sole discretion, to determine the amount of such breach or caused by such breach, and reduce the aggregate Merger Consideration by such amount so determined.

Section 9.09 <u>Interpretation</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (a) When a reference is made in this Agreement to sections, exhibits or schedules, such reference shall be to a section of, or exhibit or schedule to, this Agreement unless otherwise indicated. The table of contents and captions and headings contained in this Agreement are included solely for convenience of reference; if there is any conflict between a caption or heading and the text of this Agreement, the text shall control. Whenever the words "include," "includes" or "including" are used in this Agreement, they shall be deemed to be followed by the words "without limitation."

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (b) The Parties have participated jointly in the negotiation and drafting of this Agreement and the other agreements and documents contemplated herein. In the event an ambiguity or question of intent or interpretation arises under any provision of this Agreement or any other agreement or document contemplated herein, this Agreement and such other agreements or documents shall be construed as if drafted jointly by the Parties, and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of authorizing any of the provisions of this Agreement or any other agreements or documents contemplated herein.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (c) The Centre Disclosure Schedule and the BFC Disclosure Schedule, as well as all other schedules and all exhibits to this Agreement, shall be deemed part of this Agreement and included in any reference to this Agreement. Any matter disclosed pursuant to any section of either Disclosure Schedule shall be deemed disclosed for purposes of any other section of <u>Article III</u> or <u>Article IV</u>, respectively, to the extent that applicability of the disclosure to such other section is reasonably apparent on the face, notwithstanding the absence of a specific cross-reference, of such disclosure. The mere inclusion of an item in either Disclosure Schedule as an exception to a representation or warranty shall not be deemed an admission by either party that such item represents a material exception or fact, event or circumstance or that such item is reasonably likely to result in a Material Adverse Effect, or that any breach or violation of applicable Laws or any contract exists or has actually occurred. This Agreement shall not be interpreted or construed to require any person to take any action, or fail to take any action, if to do so would violate any applicable Law.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (d) Any reference contained in this Agreement to specific statutory or regulatory provisions or to any specific Governmental Authority shall include any successor statute or regulation, or successor Governmental Authority, as the case may be.

<u>Section 1</u>. <u>Agreement to Vote Shares</u>. Shareholder agrees that, while this Agreement is in effect, at any meeting of shareholders of Centre, however called, or at any adjournment thereof, or in any other circumstances in which Shareholder is entitled to vote, consent or give any other approval, except as otherwise agreed to in writing in advance by BFC, Shareholder shall:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (a) appear at each such meeting in person or by proxy or otherwise cause the Shares to be counted as present thereat for purposes of calculating a quorum; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (b) vote (or cause to be voted), in person or by proxy, all the Shares as to which the Shareholder has, directly or indirectly, the right to vote or direct the voting, (i) in favor of adoption and approval of the Merger Agreement and the consummation of the transactions contemplated thereby (including any amendments or modifications of the terms thereof approved by the board of directors of Centre and adopted in accordance with the terms thereof); (ii) in favor of any proposal to adjourn or postpone such meeting, if necessary, to solicit additional proxies to approve the Merger Agreement; (iii) against any action or agreement that would result in a breach of any covenant, representation or warranty or any other obligation or agreement of Centre contained in the Merger Agreement or of Shareholder

A-A-1

[**TABLE OF CONTENTS**](#TOC9)

contained in this Agreement; and (iv) against any Acquisition Proposal or any other action, agreement or transaction that is intended, or could reasonably be expected, to impede, interfere or be inconsistent with, delay, postpone, discourage or materially and adversely affect consummation of the transactions contemplated by the Merger Agreement or this Agreement.

Shareholder further agrees not to vote or execute any written consent to rescind or amend in any manner any prior vote or written consent, as a shareholder of Centre, to approve or adopt the Merger Agreement unless this Agreement shall have been terminated in accordance with its terms.

<u>Section 2</u>. <u>No Inconsistent Agreements</u>. Shareholder hereby covenants and agrees that, except for this Agreement, Shareholder (a) shall not enter into, at any time while this Agreement remains in effect, any voting agreement or voting trust or any other contract with respect to the Shares, (b) shall not grant at any time while this Agreement remains in effect, a proxy (other than as required to effect Shareholder's voting obligations in <u>Section 1</u>), consent or power of attorney in contravention of the obligations of Shareholder under this Agreement with respect to the Shares, (c) shall not commit any act, except for transfers permitted under <u>Section 3</u>, that could restrict or affect his or her legal power, authority and right to vote any of the Shares then held of record or beneficially owned by Shareholder or otherwise reasonably expected to prevent or disable Shareholder from performing any of his or her obligations under this Agreement, and (d) shall not take any action that would reasonably be expected to make any representation or warranty of Shareholder contained herein untrue or incorrect or have the effect of impeding, preventing, delaying, interfering with, disabling or adversely affecting the performance by, Shareholder of his or her obligations under this Agreement.

<u>Section 3</u>. <u>No Transfers</u>. Until the earlier of (i) the termination of this Agreement pursuant to <u>Section 7</u> and (ii) receipt of the Requisite Centre Shareholder Approval, Shareholder agrees not to, directly or indirectly, sell, transfer, pledge, assign or otherwise dispose of, or enter into any contract option, commitment or other arrangement or understanding with respect to the sale, transfer, pledge, assignment or other disposition of, any of the Shares, except the following transfers shall be permitted: (a) transfers by will or operation of Law, in which case this Agreement shall bind the transferee, (b) transfers pursuant to any pledge agreement, subject to the pledgee agreeing in writing, prior to such transfer, to be bound by the terms of this Agreement, (c) transfers in connection with estate and tax planning purposes, including transfers to relatives, trusts and charitable organizations, subject to each transferee agreeing in writing, prior to such transfer, to be bound by the terms of this Agreement, and (d) such transfers as BFC may otherwise permit in its sole discretion. Any transfer or other disposition in violation of the terms of this <u>Section 3</u> shall be null and void. As promptly as practicable following the date hereof, Shareholder shall notify Centre's transfer agent that there is a stop transfer order with respect to all of the Shares and that this Agreement places limits on the voting of the Shares; *provided*, that any such stop transfer order and notice will immediately be withdrawn and terminated by the Shareholder following the termination of this Agreement in accordance with <u>Section 7</u>.

<u>Section 4</u>. <u>Representations and Warranties of Shareholder</u>. Shareholder represents and warrants to and agrees with BFC as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (a) Shareholder has all requisite capacity and authority to enter into and perform his, her or its obligations under this Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (b) This Agreement has been duly executed and delivered by Shareholder, and assuming the due authorization, execution and delivery by BFC, constitutes a valid and legally binding obligation of Shareholder enforceable against Shareholder in accordance with its terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general applicability relating to or affecting creditors' rights and to general equity principles.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (c) The execution and delivery of this Agreement by Shareholder does not, and the performance by Shareholder of his, her or its obligations hereunder and the consummation by Shareholder of the transactions contemplated hereby will not, violate or conflict with, or constitute a default under, any agreement, instrument, contract or other obligation or any order, arbitration award, judgment or decree to which Shareholder is a party or by which Shareholder is bound, or any

A-A-2

[**TABLE OF CONTENTS**](#TOC9)

statute, rule or regulation to which Shareholder is subject or, in the event that Shareholder is a corporation, partnership, trust or other entity, any charter, bylaw or other organizational document of Shareholder.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (d) Shareholder is the record and beneficial owner of, or is the trustee that is the record holder of, and whose beneficiaries are the beneficial owners of, and has good title to all of the Shares, and the Shares are owned free and clear of any liens, security interests, charges or other encumbrances. The Shares do not include shares over which Shareholder exercises control in a fiduciary capacity for any other person or entity that is not an Affiliate of Shareholder, and no representation by Shareholder is made with respect thereto. Shareholder has the right to vote the Shares, and none of the Shares is subject to any voting trust or other agreement, arrangement or restriction with respect to the voting of the Shares, except as contemplated by this Agreement. Shareholder does not own, of record or beneficially, any shares of capital stock of Centre other than the Shares or any other securities convertible into or exercisable or exchangeable for such capital stock.

<u>Section 5</u>. <u>No Solicitation and Non-Disparagement</u>. From and after the date hereof until the termination of this Agreement pursuant to <u>Section 7</u>, Shareholder, in his, her or its capacity as a shareholder of Centre, shall not, nor shall such Shareholder authorize any partner, officer, director, advisor or representative of, such Shareholder or any of his, her or its Affiliates to, directly or indirectly (and, to the extent applicable to Shareholder, such Shareholder shall use commercially reasonable efforts to prohibit any of his, her or its representatives or Affiliates to), (a) initiate, solicit, induce or knowingly encourage, or take any action to facilitate the making of, any inquiry, offer or proposal which constitutes, or could reasonably be expected to lead to, an Acquisition Proposal, (b) except in his capacity as a director or officer of Centre and under circumstances for which such actions are permitted for Centre under the Merger Agreement, participate in any discussions or negotiations regarding any Acquisition Proposal or furnish, or otherwise afford access, to any person (other than BFC) any information or data with respect to Centre or otherwise relating to an Acquisition Proposal, (c) enter into any agreement, agreement in principle or letter of intent with respect to an Acquisition Proposal or approve or resolve to approve any Acquisition Proposal or any agreement, agreement in principle or letter of intent relating to an Acquisition Proposal, (d) solicit proxies with respect to an Acquisition Proposal (other than the Merger Agreement) or otherwise encourage or assist any party in taking or planning any action that would compete with, restrain or otherwise serve to interfere with or inhibit the timely consummation of the Merger in accordance with the terms of the Merger Agreement, (e) initiate a shareholders' vote or action by consent of Centre's shareholders with respect to an Acquisition Proposal, or (f) make publish or communicate any negative, defamatory or disparaging statements, remarks or comments concerning or alluding to Centre, BFC, Bank First, First National Bank or their products, customers, suppliers, licensees, licensors, franchisees, or employees.

<u>Section 6</u>. <u>Specific Performance; Remedies; Attorneys' Fees</u>. Shareholder acknowledges that it is a condition to the willingness of BFC to enter into the Merger Agreement that Shareholder execute and deliver this Agreement and that it will be impossible to measure in money the damage to BFC if Shareholder fails to comply with the obligations imposed by this Agreement and that, in the event of any such failure, BFC will not have an adequate remedy at law or in equity. Accordingly, Shareholder agrees that injunctive relief or other equitable remedy is the appropriate remedy for any such failure and will not oppose the granting of such relief on the basis that BFC has an adequate remedy at Law. Shareholder further agrees that Shareholder will not seek, and agrees to waive any requirement for, the securing or posting of a bond in connection with BFC's seeking or obtaining such equitable relief. In addition, after discussing the matter with Shareholder, BFC shall have the right to inform any third party that BFC reasonably believes to be, or to be contemplating, participating with Shareholder or receiving from Shareholder assistance in violation of this Agreement, of the terms of this Agreement and of the rights of BFC hereunder, and that participation by any such persons with Shareholder in activities in violation of Shareholder's agreement with BFC set forth in this Agreement may give rise to claims by BFC against such third party.

<u>Section 7</u>. <u>Term of Agreement; Termination</u>. The term of this Agreement shall commence on the date hereof. This Agreement may be terminated at any time prior to consummation of the transactions contemplated by the Merger Agreement by the mutual written agreement of the parties hereto, and shall be automatically terminated upon the earlier to occur of (a) the Effective Time, (b) the amendment of the

[**TABLE OF CONTENTS**](#TOC9)

Merger Agreement in any manner that materially and adversely affects any of Shareholder's rights set forth therein (including, for the avoidance of doubt, any reduction to the Merger Consideration), (c) termination of the Merger Agreement or (d) three (3) years from the date hereof. Upon such termination, no party shall have any further obligations or liabilities hereunder; *provided, however*, that such termination shall not relieve any party from liability for any breach of this Agreement prior to such termination.

<u>Section 8</u>. <u>Entire Agreement</u>. This Agreement represents the entire understanding of the parties hereto with reference to the transactions contemplated hereby, and this Agreement supersedes any and all other oral or written agreements heretofore made.

<u>Section 9</u>. <u>Modification and Waiver</u>. No provision of this Agreement may be modified, waived or discharged unless such waiver, modification or discharge is agreed to in writing signed by each party. No waiver by either party hereto at any time of any breach by the other party hereto of, or compliance with, any condition or provision of this Agreement to be performed by such other party shall be deemed a waiver of dissimilar provisions or conditions at the same or any prior subsequent time.

<u>Section 10</u>. <u>Severability</u>.

#### FORM OF DIRECTOR NON-COMPETITION AND NON-DISCLOSURE AGREEMENT
This Non-Competition and Non-Disclosure Agreement (the "<u>Agreement</u>"), is dated as of July 17, 2025, by and between the undersigned, an individual resident of the State of Wisconsin ("<u>Director</u>"), and Bank First Corporation, a Wisconsin corporation ("<u>BFC</u>"). All capitalized terms used but not defined herein shall have the meanings assigned to them in the Merger Agreement (defined below).

#### RECITALS:
**WHEREAS**, concurrently with the execution of this Agreement, BFC and Centre 1 Bancorp, Inc., a Wisconsin corporation ("<u>Centre</u>"), are entering into an Agreement and Plan of Merger (as such agreement may be subsequently amended or modified, the "<u>Merger Agreement</u>"), pursuant to which (i) Centre will merge with and into BFC, with BFC as the surviving entity, and (ii) The First National Bank and Trust Company, a national banking association and a direct wholly owned subsidiary of Centre ("<u>First National Bank</u>"), will merge with and into Bank First, N.A., a national banking association and a direct wholly owned subsidiary of BFC ("<u>Bank First</u>"), with Bank First as the surviving bank (collectively, the "<u>Merger</u>");

**WHEREAS**, Director is a shareholder of Centre and, as a result of the Merger and pursuant to the transactions contemplated by the Merger Agreement, Director is expected to receive significant consideration in exchange for the shares of Centre Common Stock held by Director;

**WHEREAS**, as of and prior to the date hereof, Director serves and has served as a member of the Board of Directors of Centre or First National Bank, and, therefore, Director has knowledge of the Confidential Information and Trade Secrets (each as hereinafter defined);

**WHEREAS**, as a result of the Merger, BFC and Bank First will succeed to all of the Confidential Information and Trade Secrets, for which BFC as of the Effective Time will have paid valuable consideration and desires reasonable protection; and

**WHEREAS**, it is a material prerequisite to the consummation of the Merger that each director of Centre and First National Bank, including Director, enter into this Agreement.

#### AGREEMENT:
**NOW, THEREFORE**, in consideration of these premises and the mutual covenants and undertakings herein contained, BFC and Director, each intending to be legally bound, covenant and agree as follows:

<u>Section 1</u>. <u>Restrictive Covenants</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (a) Director acknowledges that (i) BFC has separately bargained for the restrictive covenants in this Agreement; and (ii) the types and periods of restrictions imposed by the covenants in this Agreement are fair and reasonable to Director and such restrictions will not prevent Director from earning a livelihood.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (b) Having acknowledged the foregoing, solely in the event that the Merger is consummated, Director covenants and agrees with BFC as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (i) From and after the Effective Time, Director shall maintain in strict confidence and shall not, directly or indirectly, disclose, use or permit the use of any Confidential Information or Trade Secrets for so long as such information remains Confidential Information or a Trade Secret, as applicable, for any purpose, except for any disclosure that is required by applicable Law. In the event that Director is required by Law to disclose any Confidential Information, Director will: (A) if and to the extent permitted by such Law, provide BFC with prompt notice of such requirement prior to the disclosure so that BFC may waive the requirements of this Agreement or seek an appropriate protective order at BFC's sole expense; however, Director will cooperate fully with BFC in seeking such protective measures; and (B) use commercially reasonable efforts to obtain assurances that any Confidential Information disclosed will be accorded confidential treatment. If, in the absence of a waiver or protective order, Director is nonetheless, in the opinion of his or her counsel,

A-C-1

------

[**TABLE OF CONTENTS**](#TOC9)

required to disclose Confidential Information, disclosure may be made only as to that portion of the Confidential Information that counsel advises Director is required to be disclosed, and Director shall use its reasonable best efforts to ensure that such disclosed Confidential Information is accorded confidential treatment.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (ii) Except as expressly provided on Schedule I to this Agreement, for a period beginning at the Effective Time and ending two (2) years after the Effective Time, Director will not (except on behalf of or with the prior written consent of BFC), on Director's own behalf or in the service or on behalf of others, solicit or attempt to solicit any customer of BFC, Bank First, Centre or First National Bank (each a "<u>Protected Party</u>"), including actively sought prospective customers of First National Bank as of the Effective Time, for the purpose of providing products or services that are Competitive (as hereinafter defined) with those offered or provided by any Protected Party. This restriction shall apply regardless of whether the customer relationship was established prior to or after the Effective Time.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (iii) Except as expressly provided on Schedule I to this Agreement, for a period beginning at the Effective Time and ending two (2) years after the Effective Time, Director will not (except on behalf of or with the prior written consent of BFC), either directly or indirectly, on Director's own behalf or in the service or on behalf of others, act as a director, manager, officer or employee of any business which is the same as or essentially the same as the business conducted by any Protected Party and which has an office located within the Restricted Territory.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (iv) For a period beginning at the Effective Time and ending two (2) years after the Effective Time, Director will not, on Director's own behalf or in the service or on behalf of others, solicit or recruit or attempt to solicit or recruit, directly or by assisting others, any employee of any Protected Party, whether or not such employee is a full-time employee or a temporary employee of such Protected Party, whether or not such employment is pursuant to a written agreement and whether or not such employment is for a determined period or is at will, to cease working for such Protected Party; provided that the foregoing will not prevent the placement of any general solicitation for employment not specifically directed towards employees of any Protected Party or hiring any such person as a result thereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (c) For purposes of this Section 1, the following terms shall be defined as set forth below:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (i) "<u>Competitive</u>," with respect to particular products or services, means products or services that are the same as or similar to the products or services of any Protected Party.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (ii) "<u>Confidential Information</u>" means data and information:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (A) relating to the business of Centre and its Subsidiaries, including First National Bank, regardless of whether the data or information constitutes a Trade Secret;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (B) disclosed to Director or of which Director became aware as a consequence of Director's relationship with Centre and/or First National Bank;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (C) having value to Centre and/or First National Bank and, as a result of the consummation of the transactions contemplated by the Merger Agreement, BFC and/or Bank First; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (D) not generally known to competitors of Centre or BFC (including competitors to First National Bank or Bank First).

Confidential Information shall include Trade Secrets, methods of operation, names of customers, price lists, financial information and projections, personnel data and similar information; provided, however, that the terms "Confidential Information" and "Trade Secrets" shall not mean data or information that (x) has been disclosed to the public, except where such public disclosure has been made by Director without authorization from Centre or BFC, (y) has been independently developed and disclosed by others, or (z) has otherwise entered the public domain through lawful means.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (iii) "<u>Restricted Territory</u>" means each county in Wisconsin where First National Bank operates a banking office at the Effective Time and each county contiguous to each of such counties.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (iv) "<u>Trade Secret</u>" means information, without regard to form, including technical or nontechnical data, a formula, a pattern, a compilation, a program, a device, a method, a technique, a drawing, a process, financial data, financial plans, product plans or a list of actual or potential customers or suppliers, that is not commonly known by or available to the public and which information:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (A) derives economic value, actual or potential, from not being generally known to, and not being readily ascertainable by proper means by, other persons who can obtain economic value from its disclosure or use; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (B) is the subject of efforts that are reasonable under the circumstances to maintain its secrecy.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (d) Director acknowledges that irreparable loss and injury would result to BFC upon the breach of any of the covenants contained in this Section 1 and that damages arising out of such breach would be difficult to ascertain. Director hereby agrees that, in addition to all other remedies provided at law or in equity, BFC may petition and obtain from a court of law or equity, without the necessity of proving actual damages and without posting any bond or other security, both temporary and permanent injunctive relief to prevent a breach by Director of any covenant contained in this Section 1, and shall be entitled to an equitable accounting of all earnings, profits and other benefits arising out of any such breach. In the event that the provisions of this Section 1 should ever be determined to exceed the time, geographic or other limitations permitted by applicable Law, then such provisions shall be modified so as to be enforceable to the maximum extent permitted by Law. If such provision(s) cannot be modified to be enforceable, the provision(s) shall be severed from this Agreement to the extent unenforceable. The remaining provisions and any partially enforceable provisions shall remain in full force and effect.

<u>Section 2.</u> <u>Term and Termination</u>. This Agreement may be terminated at any time by the written consent of the parties hereto, and this Agreement shall be automatically terminated upon the earlier of (i) termination of the Merger Agreement and (ii) two (2) years following the Effective Time. For the avoidance of doubt, the provisions of Section 1 shall only become operative upon the consummation of the Merger but, in such event, shall survive the consummation of the Merger until two (2) years after the Effective Time. Upon termination of this Agreement, no party shall have any further obligations or liabilities hereunder, except that termination of this Agreement will not relieve a breaching party from liability for any breach of any provision of this Agreement occurring prior to the termination of this Agreement.

<u>Section 3.</u> <u>Notices</u>. All notices, requests and other communications hereunder to a party shall be in writing and shall be deemed properly given if delivered (a) personally, (b) by registered or certified mail (return receipt requested), with adequate postage prepaid thereon, (c) by properly addressed electronic mail delivery (with confirmation of delivery receipt), or (d) by reputable courier service to such party at its address set forth below, or at such other address or addresses as such party may specify from time to time by notice in like manner to the parties hereto.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **(a)** The corporation's latest available financial statements, audited and including footnote disclosure if available, but including not less than a balance sheet as of the end of a fiscal year ending not more than 16 months before the date of payment, an income statement for that year, a statement of changes in shareholders' equity for that year and the latest available interim financial statements, if any.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **(b)** A statement of the corporation's estimate of the fair value of the shares.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **(d)** A statement of the dissenter's right to demand payment under s. 180.1328 if the dissenter is dissatisfied with the payment.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **(e)** A copy of ss. 180.1301 to 180.1331.

180.1326. Failure to take action.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **(1)** If an issuer corporation does not effectuate the corporate action within 60 days after the date set under s. 180.1322 for demanding payment, the issuer corporation shall return the deposited certificates and release the transfer restrictions imposed on uncertificated shares.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **(2)** If after returning deposited certificates and releasing transfer restrictions, the issuer corporation effectuates the corporate action, the corporation shall deliver a new dissenters' notice under s. 180.1322 and repeat the payment demand procedure.

180.1327. After-acquired shares.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **(1)** A corporation may elect to withhold payment required by s. 180.1325 from a dissenter unless the dissenter was the beneficial owner of the shares before the date specified in the dissenters' notice under s. 180.1322 (2) (c) as the date of the first announcement to news media or to shareholders of the terms of the proposed corporate action.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **(2)** To the extent that the corporation elects to withhold payment under sub. (1) after effectuating the corporate action, it shall estimate the fair value of the shares, plus accrued interest, and shall pay this amount to each dissenter who agrees to accept it in full satisfaction of his or her demand. The corporation shall send with its offer a statement of its estimate of the fair value of the shares, an explanation of how the interest was calculated, and a statement of the dissenter's right to demand payment under s. 180.1328 if the dissenter is dissatisfied with the offer.

180.1328. Procedure if dissenter dissatisfied with payment or offer.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **(1)** A dissenter may, in the manner provided in sub. (2), notify the corporation of the dissenter's estimate of the fair value of his or her shares and amount of interest due, and demand payment of his or her estimate, less any payment received under s. 180.1325, or reject the offer under s. 180.1327 and demand payment of the fair value of his or her shares and interest due, if any of the following applies:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **(a)** The dissenter believes that the amount paid under s. 180.1325 or offered under s. 180.1327 is less than the fair value of his or her shares or that the interest due is incorrectly calculated.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **(b)** The corporation fails to make payment under s. 180.1325 within 60 days after the date set under s. 180.1322 for demanding payment.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **(c)** The issuer corporation, having failed to effectuate the corporate action, does not return the deposited certificates or release the transfer restrictions imposed on uncertificated shares within 60 days after the date set under s. 180.1322 for demanding payment.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **(2)** A dissenter waives his or her right to demand payment under this section unless the dissenter notifies the corporation of his or her demand under sub. (1) in writing within 30 days after the corporation made or offered payment for his or her shares. The notice shall comply with s. 180.0141.

180.1330. Court action.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **(1)** If a demand for payment under s. 180.1328 remains unsettled, the corporation shall bring a special proceeding within 60 days after receiving the payment demand under s. 180.1328 and petition the court to determine the fair value of the shares and accrued interest. If the corporation does not bring the special proceeding within the 60-day period, it shall pay each dissenter whose demand remains unsettled the amount demanded.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **(2)** The corporation shall bring the special proceeding in the circuit court for the county where its principal office or, if none in this state, its registered office is located. If the corporation is a foreign corporation without a registered office in this state, it shall bring the special proceeding in the county in this state in which was located the registered office of the issuer corporation that merged with or whose interests were acquired by the foreign corporation.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **(3)** The corporation shall make all dissenters, whether or not residents of this state, whose demands remain unsettled parties to the special proceeding. Each party to the special proceeding shall be served with a copy of the petition as provided in s. 801.14.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **(4)** The jurisdiction of the court in which the special proceeding is brought under sub. (2) is plenary and exclusive. The court may appoint one or more persons as appraisers to receive evidence and recommend decision on the question of fair value.

The dissenters are entitled to the same discovery rights as parties in other civil proceedings.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **(5)** Each dissenter made a party to the special proceeding is entitled to judgment for any of the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **(a)** The amount, if any, by which the court finds the fair value of his or her shares, plus interest, exceeds the amount paid by the corporation.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **(b)** The fair value, plus accrued interest, of his or her shares acquired on or after the date specified in the dissenter's notice under s. 180.1322 (2) (c), for which the corporation elected to withhold payment under s. 180.1327.

180.1331. Court costs and counsel fees.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (1)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **(a)** Notwithstanding ss. 814.01 to 814.04, the court in a special proceeding brought under s. 180.1330 shall determine all costs of the proceeding, including the reasonable compensation and expenses of appraisers appointed by the court and shall assess the costs against the corporation, except as provided in par. (b).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **(b)** Notwithstanding ss. 814.01 and 814.04, the court may assess costs against all or some of the dissenters, in amounts that the court finds to be equitable, to the extent that the court finds the dissenters acted arbitrarily, vexatiously or not in good faith in demanding payment under s. 180.1328.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **(2)** The parties shall bear their own expenses of the proceeding, except that, notwithstanding ss. 814.01 to 814.04, the court may also assess the fees and expenses of counsel and experts for the respective parties, in amounts that the court finds to be equitable, as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **(a)** Against the corporation and in favor of any dissenter if the court finds that the corporation did not substantially comply with ss. 180.1320 to 180.1328.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **(b)** Against the corporation or against a dissenter, in favor of any other party, if the court finds that the party against whom the fees and expenses are assessed acted arbitrarily, vexatiously or not in good faith with respect to the rights provided by this chapter.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **(3)** Notwithstanding ss. 814.01 to 814.04, if the court finds that the services of counsel and experts for any dissenter were of substantial benefit to other dissenters similarly situated, the court may award to these counsel and experts reasonable fees to be paid out of the amounts awarded the dissenters who were benefited.

#### Annex C
July 17, 2025

Board of Directors

Centre 1 Bancorp, Inc.

345 East Grand Avenue

Beloit, Wisconsin 53511

Dear Board of Directors:

Hovde Group, LLC ("<u>we</u>" or "<u>Hovde</u>") understands that Bank First Corporation ("<u>BFC</u>"), and its wholly-owned subsidiary, Bank First, N.A. ("<u>Bank First</u>") and Centre 1 Bancorp, Inc. ("<u>Centre</u>") and its wholly-owned subsidiary, The First National Bank and Trust Company, ("<u>First National Bank</u>") (Centre together with BFC, the "<u>Parties</u>" and each a "<u>Party</u>") are about to enter into an Agreement and Plan of Merger (the "<u>Agreement</u>") to be dated as of July 17, 2025. Subject to the terms and conditions of the Agreement, in accordance with the Wisconsin Business Corporation Law, at the Effective Time, Centre shall merge with and into BFC pursuant to the terms of the Agreement (the "<u>Merger</u>"), BFC shall be the Surviving Entity in the Merger and shall continue its existence as a corporation under the laws of the State of Wisconsin. As of the Effective Time, the separate corporate existence of Centre shall cease. Immediately following the Effective Time and sequentially but in effect simultaneously on the Closing Date, First National Bank shall be merged with and into Bank First (the "<u>Bank Merger</u>") in accordance with the provisions of applicable federal and state banking laws and regulations, and Bank First shall be the surviving bank (the "<u>Surviving Bank</u>") and the separate corporate existence of First National Bank shall cease. The Parties intend that for U.S. federal income tax purposes, the Merger will qualify as a "reorganization" within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended, and the Regulations promulgated thereunder (the "<u>Code</u>"), and this Agreement will be and is adopted as a "plan of reorganization" for purposes of Sections 354 and 361 of the Code.

Capitalized terms used herein that are not otherwise defined shall have the same meanings attributed to them in the Agreement, and all Article and Section references shall refer to Articles or Sections in the Agreement. For purposes of our analysis and opinion, the Agreement as used herein shall refer to the draft Agreement and Plan of Merger dated July 15, 2025 provided to Hovde by Centre.

Pursuant to the terms of Article II of the Agreement, at the Effective Time each share of Centre Common Stock (excluding Dissenting Shares and Centre Cancelled Shares) issued and outstanding shall cease to be outstanding and shall be converted into and exchanged for the right to receive 0.9200 shares (the "<u>Exchange Ratio</u>") of BFC Common Stock (the "<u>Merger Consideration</u>"). If Centre Tangible Book Value (as defined in the Agreement) as of the Closing Date is less than the Minimum Tangible Book Value, then the aggregate Merger Consideration will be reduced by an amount (the "<u>Capital Deficiency Amount</u>") equal to (A) the Minimum Tangible Book Value minus (B) Centre Tangible Book Value on the Closing Date, and the Exchange Ratio shall be adjusted to produce the aggregate Merger Consideration as reduced by such Capital Deficiency Amount.

We noted that Section 7.01(h) of the Agreement provides that Centre may terminate the Agreement if on the Determination Date the BFC Market Price results in the BFC Ratio (as defined in the Agreement) being less than certain specified values. In that event, if Centre elects to exercise its termination right, BFC shall have the option (but not the obligation) to increase the Exchange Ratio according to the calculations specified in Section 7.01(h) to result in the Adjusted Exchange Ratio. If BFC elects to proceed with the Merger by paying the additional consideration resulting from the Adjusted Exchange Ratio, then the Agreement shall remain in full force and effect in accordance with its terms, and the Exchange Ratio shall be amended to equal the Adjusted Exchange Ratio.

[**TABLE OF CONTENTS**](#TOC2)

Pursuant to Section 2.03 of the Agreement, at the Effective Time, each option to purchase Centre Common Stock granted under a Centre Stock Plan (a "<u>Centre Option</u>"), whether vested or unvested, which is outstanding immediately prior to the Effective Time shall fully vest and be automatically canceled and be converted into the right to receive an amount of cash equal to the product of (A) the excess, if any, of (1) the product of (x) the Exchange Ratio, multiplied by (y) the BFC Common Stock Price (the "<u>Per Share Cash Equivalent Consideration</u>"), over (2) the per share exercise price of the Centre Option prior to the Effective Time, multiplied by (B) the number of shares of Centre Common Stock subject to such Centre Option prior to the Effective Time, rounding up to the nearest cent. Any Centre Option with an exercise price that equals or exceeds the Per Share Cash Equivalent Consideration shall be canceled with no consideration being paid to the option holder. All amounts payable to the holders of Centre Options shall be paid as soon as practicable after, and in any event within five (5) Business Days following the Effective Time, without interest and applicable tax withholdings. Additionally, immediately prior to the Effective Time, each award of performance-based restricted stock units granted under a Centre Stock Plan (a "<u>Centre PBRSU</u>") which is outstanding immediately prior to the Effective Time shall, automatically become fully vested and shall be settled and be converted into the right to receive the Merger Consideration with respect to the total number of shares of Centre Common Stock subject to such Centre PBRSU as of immediately prior to the Effective Time (assuming that the applicable performance goals were fully achieved). Such Merger Consideration shall be delivered without interest and shall be less applicable tax withholdings.

For purposes of our analysis and opinion and with your knowledge and consent, we assumed (i) there would be no adjustment to or reduction of the Merger Consideration, (ii) there is no adjustment to the Exchange Ratio pursuant to the provisions of Section 7.01(h) (iii) the closing price of BFC Common Stock on the NASDAQ as of July 16, 2025 is $121.22, (iv) there are 1,501,016 shares of Centre Common Stock outstanding (including 24,683 shares issued due to the vesting of Centre PBRSUs), and (v) thereby the total value of the Merger Consideration is $167,396,907. Additionally, we assumed (i) there are 15,000 Centre Options outstanding with a weighted average exercise price of $74.08 per share of Centre Common Stock, (ii) based on the Exchange Ratio of 0.9200 the Per Share Cash Equivalent Consideration is $111.52, and (iii) thereby the total value of the Centre Option payments is $561,586. Accordingly, we assumed that the total value of the Merger is $167,958,493 which is the sum of the Merger Consideration of $167,396,907 and the total value of the Centre Options payments of $561,586.

We noted that Article VI of the Agreement sets forth certain normal and customary closing conditions, including: (i) the Requisite Centre Shareholder Approval at the Centre Meeting having been obtained; (ii) all Regulatory Approvals required to consummate the Merger and the Bank Merger having been obtained and remaining in full force and effect, all statutory waiting periods having expired or been terminated, and no Regulatory Approval includes the imposition of, any Burdensome Condition; (iii) the Registration Statement shall have become effective and no stop order shall have been issued by the SEC or any Governmental Authority; (iv) BFC and Centre shall have received opinions from their respective legal counsel each dated as of the Closing Date to the effect that, the Merger will be treated for federal income tax purposes as a "reorganization" within the meaning of Section 368(a) of the Code; (v) Shares of BFC Common Stock to be issued in connection with the Merger shall have been approved for listing on the Trading Market; and (vi) Dissenting Shares shall be less than 10% of the issued and outstanding shares of Centre Common Stock.

We also noted that the Merger may be terminated if any of the conditions of Article VII of the Agreement are met, which include among other normal and customary conditions the following; (i) by the mutual consent of Centre and BFC; (ii) by the board of directors of either BFC or Centre in the event any Regulatory Approval required for consummation of the Merger and the Bank Merger shall have been denied by final, non-appealable action by any applicable Governmental Authority or an application therefor shall have been permanently withdrawn at the request of a Governmental Authority; (iii) by either BFC or Centre if the Requisite Centre Shareholder Approval at the Centre Meeting shall not have been obtained: (iv) by either BFC or Centre if the Merger shall not have been consummated on or before April 30, 2026, provided, however, that such date will be automatically extended to May 31, 2026, if the only outstanding condition to Closing is the receipt of all Regulatory Approvals; (v) by BFC if the board of directors of Centre (A) withdraws, qualifies, amends, modifies or withholds the Centre Recommendation (B) approves or recommends an Acquisition Proposal, (D) fails to publicly recommend against a publicly announced Acquisition Proposal within three (3) Business Days of being requested to do so by BFC, (E) fails to publicly

[**TABLE OF CONTENTS**](#TOC2)

reconfirm the Centre Recommendation within three (3) Business Days of being requested to do so by BFC, (vi) by Centre at any time before obtaining the Requisite Centre Shareholder Approval if the board of directors of Centre authorizes Centre to enter into a binding definitive agreement in respect of a Superior Proposal with a third party, provided, that Centre shall pay to BFC the Termination Fee of $5,038,755 (based on the closing price of BFC Common Stock on the NASDAQ as of July 16, 2025 of $121.22 per share) by wire transfer of immediately available funds. In addition, if Centre terminates the Agreement pursuant to any of the provisions of Section 7.01(f) as set forth immediately above in clauses (A) through (F) of the proceeding sentence, then Centre shall pay to BFC the Termination Fee by wire transfer in immediately available funds.

With your consent and for purposes of our analysis and opinion, we have assumed that (i) there is no adjustment to the Exchange Ratio pursuant to the provisions of Section 7.01(h), (ii) all of the closing conditions set forth in Article VI of the Agreement are satisfied, (iii) the Merger is not terminated pursuant to any of the provisions set forth in Article VII of the Agreement, and (iv) the Merger will proceed and be consummated in accordance with the terms of the Agreement.

You have requested our opinion, subject to the terms, conditions, and qualifications set forth herein, that the Merger Consideration is fair, from a financial point of view, to the holders of shares of Centre Common Stock. This opinion addresses only the fairness of the Merger Consideration, and we are not opining on any individual stock, cash, or other components of the consideration.

During the course of our engagement and for the purposes of the opinion set forth herein, we have:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (i)

reviewed a draft of the Agreement dated July 15, 2025 provided to Hovde by Centre;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (ii)

reviewed audited financial statements for Centre and First National Bank for the twelve month periods ended December 31, 2022, December 31, 2023 and December 31, 2024 and the unaudited statements for the three month period ended March 31, 2025;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (iii)

reviewed audited financial statements for BFC and Bank First for the twelve month periods ended December 31, 2022, December 31, 2023 and December 31, 2024 and the unaudited statements for the three month period ended March 31, 2025;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (iv)

reviewed certain historical publicly available business and financial information concerning Centre;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (v)

reviewed certain internal financial statements and other financial and operating data concerning Centre;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (vi)

reviewed financial projections prepared in consultation with and approved by certain members of the senior management of Centre;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (vii)

discussed with certain members of senior management of Centre the business, financial condition, results of operations and future prospects of Centre, the history and past and current operations of Centre, and Centre's assessment of the rationale for the Merger;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (viii)

assessed current general economic, market and financial conditions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (ix)

reviewed the terms of recent merger, acquisition and control investment transactions, to the extent publicly available, involving financial institutions and financial institution holding companies that we considered relevant;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (x)

taken into consideration our experience in other similar transactions and securities valuations as well as our knowledge of the banking and financial services industry; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (xi)

performed such other analyses and considered such other factors as we have deemed appropriate.

We have assumed, without investigation, that there have been, and from the date hereof through the Closing there will be, no material changes in the financial condition and results of operations of BFC or Centre since the date of the latest financial information described above. We have further assumed, without independent verification, that the representations and financial and other information included in the

------

[**TABLE OF CONTENTS**](#TOC2)

Agreement and all other related documents and instruments that are referred to therein or otherwise provided to us by Centre and BFC are true and complete. We have relied upon the management of Centre as to the reasonableness and achievability of the financial forecasts, projections and other forward-looking information provided to Hovde by Centre, and we assumed such forecasts, projections and other forward-looking information have been reasonably prepared by Centre on a basis reflecting the best currently available information and Centre's judgments and estimates. We have assumed that such forecasts, projections and other forward-looking information would be realized in the amounts and at the times contemplated thereby, and we do not assume any responsibility for the accuracy or reasonableness thereof. We have been authorized by Centre to rely upon such forecasts, projections and other information and data, and we express no view as to any such forecasts, projections or other forward-looking information or data, or the bases or assumptions on which they were prepared.

In performing our review, we have assumed and relied upon the accuracy and completeness of all the financial and other information that was available to us from public sources that was provided to us by Centre or their respective representatives or that was otherwise reviewed by us for purposes of rendering this opinion. We have further relied on the assurance of the management of Centre that they are not aware of any facts or circumstances that would make any of such information inaccurate or misleading. We have not been asked to undertake, and have not undertaken, an independent verification of any of such information, and we do not assume any responsibility or liability for the accuracy or completeness thereof. We have assumed that each party to the Agreement would advise us promptly if any information previously provided to us became inaccurate or was required to be updated during the period of our review.

We are not experts in the evaluation of loan and lease portfolios for the purpose of assessing the adequacy of the allowances for losses with respect thereto. We have assumed that such allowances for Centre are, in the aggregate, adequate to cover such losses. We were not requested to make, and have not made, an independent evaluation, physical inspection or appraisal of the assets, properties, facilities, or liabilities (contingent or otherwise) of Centre, the collateral securing any such assets or liabilities, or the collectability of any such assets or liabilities, and we were not furnished with any such evaluations or appraisals, nor did we review any loan or credit files of Centre.

We have undertaken no independent analysis of any pending or threatened litigation, regulatory action, possible unasserted claims or other contingent liabilities to which BFC or Centre is a party or may be subject, and our opinion makes no assumption concerning, and therefore does not consider, the possible assertion of claims, outcomes or damages arising out of any such matters. We have also assumed, with your consent, that neither BFC nor Centre is committed to any material transaction, including without limitation any financing, recapitalization, acquisition or merger, divestiture or spin-off, other than the Merger contemplated by the Agreement.

We have relied upon and assumed, with your consent and without independent verification, that the Merger will be consummated substantially in accordance with the terms set forth in the Agreement, without any waiver of material terms or conditions by BFC or Centre or any other party to the Agreement and that the final Agreement will not differ materially from the draft of the Agreement we reviewed. We have assumed that the Merger will be consummated in compliance with all applicable laws and regulations. Centre has advised us that they are not aware of any factors that would impede any necessary regulatory or governmental approval of the Merger. We have assumed that the necessary regulatory and governmental approvals as granted will not be subject to any conditions that would be unduly burdensome on BFC or Centre or would have a material adverse effect on the contemplated benefits of the Merger.

Our opinion does not consider, include or address: (i) the legal, tax, accounting, or regulatory consequences of the Merger on Centre or its shareholders; or (ii) any advice or opinions provided by any other advisor to the Board of Directors of Centre; or (iii) any other strategic alternatives that might be available to Centre.

Our opinion does not constitute a recommendation to Centre as to whether or not Centre should enter into the Agreement or to any shareholders of Centre Common Stock as to how such shareholders should vote at any meetings of shareholders called to consider and vote upon the Merger. Our opinion does not address the underlying business decision by either Centre or BFC to proceed with the Merger or the fairness of the amount or nature of the compensation, if any, to be received by any of the officers, directors or

------

[**TABLE OF CONTENTS**](#TOC2)

employees of Centre relative to the value of the Merger Consideration to be paid with respect to the Merger. Our opinion should not be construed as implying that the Merger Consideration is necessarily the highest or best form of financial compensation that could be obtained in a merger or combination transaction of Centre with BFC or any other financial institution. Other than as specifically set forth herein, we are not expressing any opinion with respect to the terms and provisions of the Agreement or the enforceability of any such terms or provisions. Our opinion is not a solvency opinion and does not in any way address the solvency or financial condition of BFC or Centre.

This opinion was approved by Hovde's fairness opinion committee. This letter is directed solely to the Board of Directors of Centre and is not to be used for any other purpose or quoted or referred to, in whole or in part, in any registration statement, prospectus, proxy statement, or any other document, except in each case in accordance with our prior written consent; <u>provided</u>, <u>however</u>, we hereby consent to the inclusion and reference to this letter in any registration statement, proxy statement or information statement to be delivered to the holders of shares of Centre Common Stock in connection with the Merger if, and only if, (i) this letter is quoted in full or attached as an exhibit to such document, (ii) this letter has not been withdrawn prior to the date of such document, and (iii) any description of or reference to Hovde or the analyses performed by Hovde or any summary of this opinion in such document is in a form acceptable to Hovde and its counsel in the exercise of their reasonable judgment.

Our opinion is based solely upon the information available to us and described above, and the economy, market and other circumstances as they exist as of the date hereof. Events occurring and information that becomes available after the date hereof could materially affect the assumptions and analyses used in preparing this opinion. We have not undertaken to update, revise, reaffirm or withdraw this opinion or to otherwise comment upon events occurring or information that becomes available after the date hereof.

In arriving at this opinion, Hovde did not attribute any particular weight to any single analysis or factor considered by it but rather made qualitative judgments as to the significance and relevance of each analysis and factor. Accordingly, Hovde believes that its analyses must be considered as a whole and that selecting portions of its analyses, without considering all analyses, would create an incomplete view of the process underlying this opinion.

Hovde, as part of its investment banking business, regularly performs valuations of businesses and their securities in connection with mergers and acquisitions and other corporate transactions. Pursuant to our engagement agreement with Centre, we will receive from Centre an opinion fee that is contingent upon the issuance of this opinion letter and a completion fee less the opinion fee contingent upon the consummation of the Merger. The Company has also agreed to indemnify us and our affiliates for certain liabilities that may arise out of our engagement.

In the past two years preceding the date of this opinion, Hovde has not provided investment banking or financial advisory services to either BFC or Centre for which it received a fee. We or our affiliates may presently or in the future seek or receive compensation from BFC in connection with future transactions, or in connection with potential advisory services and corporate transactions. In the ordinary course of our business as a broker/dealer, we may from time to time purchase securities from, and sell securities to, BFC or Centre or their affiliates, and as a market maker in securities, Hovde may from time to time have a long or short position in, and buy or sell, debt or equity securities of BFC or Centre for Hovde's own accounts and for the accounts of Hovde's customers. Except for the foregoing, during the past two years there have not been and there currently are no mutual agreements regarding any future material transactions between Hovde and either BFC or Centre.

Based upon and subject to the foregoing review, assumptions and limitations, we are of the opinion, as of the date hereof, that the Merger Consideration is fair, from a financial point of view, to the holders of shares of Centre Common Stock.

Sincerely,
