Rhea-AI Filing Summary

Bank First Corporation is planning a stock‑for‑stock acquisition of PSB Holdings, Inc. in a strategic bank merger. Each PSB common share will be converted into 0.3470 shares of Bank First common stock, valuing the deal at approximately $202.9 million based on Bank First’s May 18, 2026 closing price. The transaction is expected to close in the fourth quarter of 2026, subject to PSB shareholder approval, regulatory clearances, SEC effectiveness of a Form S‑4 registration statement, and other customary conditions, including tax opinions that the deal qualifies as a reorganization under Section 368(a). A side letter fixes the earliest closing date at December 4, 2026 and, if closing is delayed beyond that date for reasons not attributable to PSB, allows PSB’s board to declare a one‑time special dividend of $1.00 per common share without reducing tangible book value for deal purposes. The combined company is projected to have about $7.6 billion in assets, with management targeting roughly 14.2% EPS accretion in 2027, about 1.0% tangible book value dilution at closing, and a 0.25‑year earnback period.

Positive

  • Double‑digit projected EPS accretion – Management targets approximately 14.2% earnings per share accretion in 2027 and 12.0% in 2028 from the PSB acquisition, driven largely by 35% cost savings from PSB’s expense base.
  • Limited tangible book value dilution – Estimated tangible book value dilution is about 1.0% at closing with a 0.25‑year earnback period using the crossover method, while maintaining a projected CET1 ratio of 11.1% at close.
  • Meaningful balance‑sheet scale – Based on March 31, 2026 data, the combined company is projected to have roughly $7.6 billion in assets, $5.6 billion in loans, and $6.3 billion in deposits, enhancing Bank First’s competitive position in Wisconsin.

Negative

  • Integration and execution risk – The combination depends on realizing 35% cost savings, integrating PSB’s operations, and completing another large deal soon after the Centre 1 Bancorp acquisition, all of which could pressure performance if delayed or disrupted.
  • Share issuance and dilution to existing holders – The all‑stock structure requires Bank First to issue new shares to PSB shareholders, creating tangible book value dilution and the potential for earnings impact if projected synergies are not achieved.
  • Deal‑specific termination economics – PSB may owe Bank First a termination fee of $8,117,163 in certain scenarios, adding financial consequences if the transaction fails due to competing proposals or specified breaches.

Insights

All‑stock PSB acquisition materially scales Bank First with targeted EPS accretion and limited TBV dilution.

Bank First is acquiring PSB Holdings in an all‑stock transaction valued at about $202.9 million, using a fixed exchange ratio of 0.3470 Bank First shares per PSB share. Pro forma, the combined bank is projected to reach roughly $7.6 billion in assets, significantly expanding presence across Wisconsin.

Management projects cost saves equal to 35% of PSB’s expense base, driving expected EPS accretion of 14.2% in 2027 and 12.0% in 2028. Tangible book value dilution is estimated at only 1.0% at closing with an earnback period of 0.25 year using the crossover method, leaving pro forma common equity tier 1 at 11.1% and a leverage ratio of 9.2% at closing.

Risks highlighted include execution of projected cost savings, integration of PSB’s operations and culture, and the usual regulatory and shareholder approvals. The structure also entails share issuance and associated dilution, as well as a termination fee of $8,117,163 payable by PSB in specified break scenarios. Overall, the disclosed projections suggest a financially attractive, though integration‑dependent, regional consolidation strategy.

Agreement and Plan of Merger regulatory
"On May 19, 2026, Bank First Corporation ... entered into an Agreement and Plan of Merger with PSB Holdings, Inc."
An Agreement and Plan of Merger is a formal document where two companies agree to combine into one, outlining how the process will happen. It’s like a step-by-step plan for merging, and it matters because it shows both sides have agreed on the details before the official transition takes place.
tangible book value financial
"the aggregate merger consideration is subject to a downward adjustment if PSB’s tangible book value ... is less than $122,837,000"
Tangible book value is the accounting measure of a company’s net worth after removing intangible items like goodwill, patents and trademarks, leaving only physical and financial assets minus liabilities. For investors it offers a clearer view of the company’s hard-asset backing per share—like estimating the cash you could get by selling the furniture, machinery and cash in a house—helping gauge downside risk and whether a stock may be cheaply valued.
Section 368(a) regulatory
"a tax opinion to the effect that the Merger will qualify as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code"
termination fee financial
"PSB will pay BFC a termination fee equal to $8,117,163 in the event"
A termination fee is a payment required if one party ends a contract before its agreed-upon end date. It acts like a penalty or compensation to the other party for canceling early, similar to a fee you might pay for breaking a lease or canceling a service contract. For investors, it matters because it can influence a company's decisions and financial obligations related to ending agreements prematurely.
core deposit intangible financial
"Core deposit intangible of 3.00%, amortized over 10 years SYD"
Core deposit intangible is an accounting asset that represents the value of customer deposits a bank gains, usually through an acquisition, because those deposits provide a stable, low-cost source of funding. Think of it like paying for a loyal customer list that will save the bank money over time; it is written down over several years and affects reported earnings and the apparent cost of acquiring new funds, so investors watch it to understand future profitability and capital impact.
Form S-4 regulatory
"BFC will file with the SEC a registration statement on Form S-4 that will include a proxy statement of PSB"
A Form S-4 is a legal document that companies file with the government to announce and explain a major business move, such as a merger or acquisition. It provides detailed information to help investors understand how the deal might affect the company's value and future prospects, similar to a detailed blueprint that clarifies the impact of a significant change.

Item 1.01Entry Into a Material Definitive Agreement

 

On May 19, 2026, Bank First Corporation, a Wisconsin corporation (“BFC”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) with PSB Holdings, Inc., a Wisconsin corporation (“PSB”), whereby PSB will be merged with and into BFC (the “Merger”). Pursuant to entering into the Merger Agreement, BFC’s wholly-owned subsidiary bank, Bank First, N.A. (“Bank First”), and PSB’s wholly-owned subsidiary bank, Peoples State Bank (“Peoples State Bank”), will enter into a Bank Plan of Merger and Merger Agreement whereby Peoples State Bank will be merged with and into Bank First immediately following the merger of PSB with and into BFC with Bank First continuing as the surviving bank.

 

The Merger Agreement has been unanimously approved by the boards of directors of BFC and PSB. The transaction is expected to close in the fourth quarter of 2026, subject to customary closing conditions discussed below.

 

Merger Consideration. Pursuant to the Merger Agreement, each outstanding share of PSB common stock issued and outstanding immediately prior to the effective time of the Merger will be converted into the right to receive 0.3470 shares of common stock of BFC. Notwithstanding the foregoing, the aggregate merger consideration is subject to a downward adjustment if PSB’s tangible book value (as calculated per the Merger Agreement) is less than $122,837,000 at the effective time of the Merger. Each outstanding share of BFC’s common stock shall remain outstanding and unaffected by the Merger. In addition, each outstanding share of PSB preferred stock will be converted into the right to receive consideration pursuant to a preferred stock transaction to be entered into prior to, and effective as of, the closing, pursuant to which BFC intends to enter into binding agreements to purchase all outstanding shares of PSB preferred stock from the holders thereof. If BFC does not enter into such agreements with all holders of PSB preferred stock, then each outstanding share of PSB preferred stock will instead be converted into the right to receive one share of a newly designated series of preferred stock of BFC having rights, preferences and privileges that, taken as a whole, are substantially comparable to, and not materially less favorable than, those of the PSB preferred stock immediately prior to the effective time.

 

Representations and Warranties. The Merger Agreement contains usual and customary representations and warranties that BFC and PSB made to each other as of specific dates. The assertions embodied in those representations and warranties were made solely for purposes of the contract between BFC and PSB and may be subject to important qualifications and limitations agreed to by the parties in connection with negotiating certain terms. Moreover, certain of the representations and warranties are subject to a contractual standard of materiality that may be different from what may be viewed as material to shareholders, and the representations and warranties may have been used to allocate risk between BFC and PSB rather than establishing matters of fact. For the foregoing reasons, no one should rely on such representations, warranties, covenants or other terms, provisions or conditions as statements of factual information regarding BFC or PSB at the time they were made or otherwise. The representations and warranties of the parties will not survive the closing.

 

Covenants; No Solicitation. Each party also has agreed to customary covenants, including, among others, covenants relating to the conduct of its business during the interim period between the execution of the Merger Agreement and the consummation of the Merger. Additionally, PSB has agreed (i) not to initiate, solicit, induce or knowingly encourage, or take any action to facilitate the making of any acquisition proposal or, subject to certain exceptions, participate in discussions or negotiations regarding, or furnish any non-public information relating to, any acquisition proposal and (ii) subject to certain exceptions, not to withdraw or modify, in a manner adverse to BFC, the recommendation of the PSB board of directors that PSB’s shareholders approve the Merger Agreement and the Merger. In the event that PSB receives an acquisition proposal that the PSB board of directors determines is superior to the Merger, BFC will have an opportunity to match the terms of such proposal, subject to certain requirements.

 

 

 

Conditions to Closing. Consummation of the Merger is subject to various customary conditions, including, among others, (i) approval of the Merger Agreement and the Merger by shareholders of PSB; (ii) the shares of BFC common stock to be issued in the Merger having been approved for listing on the National Market System of The Nasdaq Stock Market (“NASDAQ”); (iii) the receipt of certain regulatory approvals; (iv) no injunctions or other legal restraints preventing the consummation of the Merger; (v) the U.S. Securities and Exchange Commission (“SEC”) having declared effective BFC’s registration statement covering the issuance of shares of BFC’s common stock, and, if necessary, the new series of BFC preferred stock, in the Merger; (vi) the receipt by each party of a tax opinion to the effect that the Merger will qualify as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended; (vii) the accuracy of representations and warranties of the parties and compliance by the parties with their respective covenants and obligations under the Merger Agreement (subject to customary materiality qualifiers); and (viii) the absence of a material adverse effect with respect to PSB (and, in certain respects, BFC), as specified in the Merger Agreement.

 

Termination. The Merger Agreement may be terminated in certain circumstances, including: (i) by mutual written agreement of the parties, (ii) by either party 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 an application for such approval has been permanently withdrawn at the request of a governmental authority, (iii) by either party if the approval of the shareholders of PSB is not obtained, (iv) by either party 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 the earlier of thirty days or two days prior to the expiration of the Merger Agreement, (v) by either party if the Merger is not consummated on or before December 4, 2026 (subject to extension to February 19, 2027), (vi) by BFC if PSB’s board of directors breaches its obligation not to solicit any acquisition proposal, changes its recommendation with respect to the Merger in accordance with the terms of the Merger Agreement, or breaches its obligation to call a special PSB shareholder meeting to vote on the Merger, or (vii) by PSB in order to enter into an agreement to a superior proposal.

 

PSB also has the right to terminate the Merger Agreement in the event that (A) the price of BFC’s common stock declines by more than 15% from May 18, 2026, and (B) the decline of the price of BFC’s common stock is 15% greater than the change in the price of the NASDAQ Bank Index over the same period of time. In the event that such a decline in the price of BFC’s common stock occurs, BFC shall have the right, but not the obligation, to “fill” the decline by adjusting the merger consideration as further described in the Merger Agreement.

 

Termination Fee. PSB will pay BFC a termination fee equal to $8,117,163 in the event (i) the Merger Agreement is terminated by BFC because PSB’s board of directors breaches its obligation not to solicit any acquisition proposal, changes its recommendation with respect to the Merger in accordance with the terms of the Merger Agreement, or breaches its obligation to call a special PSB shareholder meeting to vote on the Merger, (ii) PSB terminates this agreement in order to accept a superior proposal, or (iii) the Merger Agreement is terminated (A) by either BFC or PSB because the required PSB shareholder approval is not obtained or (B) the Merger Agreement is terminated by BFC because of PSB’s material breach of representations, warranties or covenants, and, in the case of clause (iii), an acquisition proposal was publicly announced or received prior to termination and PSB enters into or completes such an acquisition transaction within 12 months following such termination (subject to the thresholds specified in the Merger Agreement).

 

Corporate Governance. Pursuant to the Merger Agreement, BFC will expand its board of directors by one seat to appoint one member of PSB’s board to be selected by BFC in its discretion following the Effective Time and no later than BFC’s 2027 annual meeting of shareholders. If selected, this individual must meet BFC’s director standards, comply with its governance policies, and qualify as an independent director under NASDAQ rules.

 

The foregoing summary of the Merger Agreement is not complete and is qualified in its entirety by reference to the full text of the Merger Agreement and certain exhibits attached thereto, a copy of which is filed as Exhibit 2.1 attached hereto and incorporated by reference herein. The Merger Agreement should not be read alone, but should instead be read in conjunction with the other information regarding BFC, its affiliates and their respective businesses, and the information regarding the Merger Agreement and the Merger that will be contained in, or incorporated by reference into, the registration statement on Form S-4 of BFC that will include a proxy statement of PSB and a prospectus of BFC and that will be filed with the SEC.

 

 

 

Voting Agreements

 

In connection with entering into the Merger Agreement, the directors and executive officers of PSB have entered into voting agreements (the “PSB Voting Agreements”), pursuant to which each such director and executive officer agreed to vote his, her or its shares of PSB common stock in favor of approval of the Merger Agreement and the consummation of the transactions contemplated therein and against certain other actions, proposals, transactions or agreements that would be detrimental to the consummation of the Merger. The PSB Voting Agreements generally prohibit the sale or transfer of the shares held by each such shareholder until the earlier of (i) termination of the Merger Agreement or (ii) receipt of the approval of the shareholders of PSB. The PSB Voting Agreements terminate upon the earlier of (i) the consummation of the Merger, (ii) the amendment of the Merger Agreement in any manner that materially and adversely affects any rights of the shareholder, (iii) the termination of the Merger Agreement or (iv) three years from the date of the PSB Voting Agreements.

 

The foregoing summary of the PSB Voting Agreements is qualified in its entirety by reference to the complete text of such documents, a form of which is included as Exhibit A to the Merger Agreement, filed as Exhibit 2.1 attached hereto and which is incorporated herein by reference.

 

Director Non-Compete Agreements

 

In connection with entering into the Merger Agreement, each of the directors of PSB and Peoples State Bank will enter into a Non-Competition and Non-Disclosure Agreement with BFC, which contains provisions related to the non-disclosure of confidential information and trade secrets, non-solicitation of customers with whom such directors had material contact, non-competition within a restricted territory, and non-recruitment of employees.

 

The foregoing summary of the Non-Competition and Non-Disclosure Agreement is qualified in its entirety by reference to the complete text of such document, a form of which is included as Exhibit C to the Merger Agreement, filed as Exhibit 2.1 attached hereto and which is incorporated herein by reference.

 

Side Letter Agreement

 

In connection with the Merger Agreement, BFC and PSB entered into a side letter agreement (the “Side Letter Agreement”) pursuant to which, the parties agreed that the closing will not occur until December 4, 2026. In consideration of such agreement, BFC agreed that, if all conditions to closing have been satisfied or waived such that the closing could have occurred prior to such date (such date, the “Default Closing Date”), BFC will be deemed to have waived its right to terminate the Merger Agreement for material breaches of PSB’s representations and warranties occurring after the Default Closing Date, subject to specified exceptions, including breaches resulting in or reasonably expected to result in a material adverse effect and material breaches of PSB’s covenants.

 

In addition, the Side Letter Agreement provides that, if the closing has not occurred on or before December 4, 2026 (subject to specified conditions), PSB may declare and pay a one-time special dividend of $1.00 per share to holders of its common stock immediately prior to the closing, which will not reduce PSB tangible common book value for purposes of the Merger Agreement. The Side Letter Agreement limits PSB’s ability to declare or pay such dividend by providing that PSB may not do so if the failure to consummate the closing by December 4, 2026 is attributable to PSB, including as a result of PSB’s material breach of any representation, warranty or covenant contained in the Merger Agreement or due to the fault of PSB or its vendors.

 

The foregoing summary of the Side Letter Agreement is qualified in its entirety by reference to the complete text of the Side Letter Agreement, which is filed as Exhibit 10.1 to this Current Report on Form 8-K and is incorporated herein by reference.

Cautionary Statements Regarding Forward-Looking Information.

 

This Current Report contains “forward-looking statements” as defined in the Private Securities Litigation Reform Act of 1995. In general, forward-looking statements usually use words such as “may,” “believe,” “expect,” “anticipate,” “intend,” “should,” “plan,” “estimate,” “predict,” “continue” and “potential” or the negative of these terms or other comparable terminology, including statements related to the expected timing of the closing of the Merger, the expected returns and other benefits of the Merger to shareholders, expected improvement in operating efficiency resulting from the Merger, estimated expense reductions resulting from the transactions and the timing of achievement of such reductions, the impact on and timing of the recovery of the impact on tangible book value, and the effect of the Merger on BFC’s capital ratios. Forward-looking statements represent management’s beliefs, based upon information available at the time the statements are made, with regard to the matters addressed; they are not guarantees of future performance. Forward-looking statements are subject to numerous assumptions, risks and uncertainties that change over time and could cause actual results or financial condition to differ materially from those expressed in or implied by such statements.

 

Factors that could cause or contribute to such differences include, but are not limited to (1) the risk that the cost savings and any revenue synergies from the Merger may not be realized or take longer than anticipated to be realized, (2) disruption from the Merger with customers, suppliers, employee or other business partners, (3) the occurrence of any event, change or other circumstances that could give rise to the termination of the Merger Agreement, (4) the risk of successful integration of PSB’s business into BFC, (5) the failure to obtain the necessary approval by the shareholders of PSB, (6) the amount of the costs, fees, expenses and charges related to the Merger, (7) the ability of the parties to obtain required governmental approvals of the Merger on expected terms or in a timely manner, or at all, (8) reputational risk and the reaction of each of the companies’ customers, suppliers, employees or other business partners to the Merger, (9) the failure of the closing conditions in the Merger Agreement to be satisfied, or any unexpected delay in closing of the Merger, (10) the risk that the integration of PSB’s operations into the operations of BFC will be materially delayed or will be more costly or difficult than expected, (11) the possibility that the Merger may be more expensive to complete than anticipated, including as a result of unexpected factors or events, (12) the dilution caused by BFC’s issuance of additional shares of its common stock in the Merger, (13) the successful integration of the recently completed acquisition of Centre 1 Bancorp, Inc., and (14) general competitive, economic, political and market conditions.

 

Many of these factors are beyond BFC’s and PSB’s ability to control or predict. Other relevant risk factors may be detailed from time to time in BFC’s press releases and filings with the Securities and Exchange Commission (the “SEC”). Consequently, no forward-looking statement can be guaranteed. Neither BFC nor PSB undertakes any obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise, except as required by law. For any forward-looking statements made in this news release or any related documents, BFC and PSB claim protection of the safe harbor for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995.

MANITOWOC, Wis. and WAUSAU, Wis., May 19, 2026 /PRNewswire/ -- Bank First Corporation (Nasdaq: BFC) (“Bank First”), the holding company of Bank First, N.A., announced today that it has entered into an Agreement and Plan of Merger with PSB Holdings, Inc. (“Peoples”), parent company of Peoples State Bank, a Wisconsin state-chartered bank, under which Bank First will acquire 100% of the common stock of Peoples in an all-stock transaction.

 

Under the terms of the Agreement and Plan of Merger, each Peoples shareholder will have the right to receive 0.3470 of a share of Bank First’s common stock in exchange for each share of Peoples common stock.

Forward-Looking Statements

 

This news release contains “forward-looking statements” as defined in the Private Securities Litigation Reform Act of 1995. In general, forward-looking statements usually use words such as “may,” “believe,” “expect,” “anticipate,” “intend,” “should,” “plan,” “estimate,” “predict,” “continue” and “potential” or the negative of these terms or other comparable terminology, including statements related to the expected timing of the closing of the merger, the expected returns and other benefits of the merger to shareholders, expected improvement in operating efficiency resulting from the merger, estimated expense reductions resulting from the transactions and the timing of achievement of such reductions, the impact on and timing of the recovery of the impact on tangible book value, and the effect of the merger on Bank First’s capital ratios. Forward-looking statements represent management’s beliefs, based upon information available at the time the statements are made, with regard to the matters addressed; they are not guarantees of future performance. Forward-looking statements are subject to numerous assumptions, risks and uncertainties that change over time and could cause actual results or financial condition to differ materially from those expressed in or implied by such statements.

 

Factors that could cause or contribute to such differences include, but are not limited to (1) the risk that the cost savings and any revenue synergies from the merger may not be realized or take longer than anticipated to be realized, (2) disruption from the merger with customers, suppliers, employee or other business partners, (3) the occurrence of any event, change or other circumstances that could give rise to the termination of the merger agreement, (4) the risk of successful integration of Peoples’ business into Bank First, (5) the failure to obtain the necessary approval by the shareholders of Peoples, (6) the amount of the costs, fees, expenses and charges related to the merger, (7) the ability of the parties to obtain required governmental approvals of the merger on expected terms or in a timely manner, or at all, (8) reputational risk and the reaction of each of the companies’ customers, suppliers, employees or other business partners to the merger, (9) the failure of the closing conditions in the merger agreement to be satisfied, or any unexpected delay in closing of the merger, (10) the risk that the integration of Peoples’ operations into the operations of Bank First will be materially delayed or will be more costly or difficult than expected, (11) the possibility that the merger may be more expensive to complete than anticipated, including as a result of unexpected factors or events, (12) the dilution caused by Bank First’s issuance of additional shares of its common stock in the merger, (13) the successful integration of the recently completed acquisition of Centre 1 Bancorp, Inc., and (14) general competitive, economic, political and market conditions.

 

Many of these factors are beyond Bank First’s and Peoples’ ability to control or predict. Other relevant risk factors may be detailed from time to time in Bank First’s press releases and filings with the Securities and Exchange Commission (the “SEC”). Consequently, no forward-looking statement can be guaranteed. Neither Bank First nor Peoples undertakes any obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise, except as required by law. For any forward-looking statements made in this news release or any related documents, Bank First and Peoples claim protection of the safe harbor for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995.

FAQ

What did Bank First Corporation (BFC) announce regarding PSB Holdings?

Bank First announced a definitive Agreement and Plan of Merger to acquire PSB Holdings, Inc. in an all-stock transaction. PSB will merge into Bank First, followed by Peoples State Bank merging into Bank First, N.A., creating a larger Wisconsin-focused community banking franchise.

What is the deal value and exchange ratio for the Bank First–PSB merger?

Each PSB common share will convert into 0.3470 Bank First common shares. Based on Bank First’s May 18, 2026 closing price of $143.66, the aggregate consideration is approximately $202.9 million, implying about $49.85 in value per PSB share at that reference price.

When is the Bank First and PSB merger expected to close?

The parties expect the transaction to close in the fourth quarter of 2026. A side letter provides that closing will not occur until December 4, 2026, aligning regulatory approvals, shareholder votes, and operational readiness before legal consummation and systems conversion.

How large will the combined Bank First and PSB franchise be after closing?

Using March 31, 2026 financials, management projects the combined company will have about $7.6 billion in assets, $5.6 billion in loans, and $6.3 billion in deposits. The pro forma organization is also expected to operate roughly 50 branches across its Midwest footprint.

What financial impact does Bank First project from acquiring PSB?

The merger is projected to be accretive to earnings, with about 14.2% EPS accretion in 2027 and 12.0% in 2028. Tangible book value per share dilution is estimated at roughly 1.0% at closing, with a 0.25‑year earnback period using the crossover method, assuming planned cost savings.

What are key conditions and risks for completing the Bank First–PSB merger?

Completion requires PSB shareholder approval, regulatory approvals, an effective Form S-4 registration statement, and customary conditions including absence of material adverse effects. Disclosed risks include integration challenges, synergy realization, potential delays, and dilution from new share issuance.

Can PSB shareholders receive a special dividend before the merger closes?

Under a side letter, if closing has not occurred by December 4, 2026 and the delay is not attributable to PSB, PSB’s board may declare a one-time $1.00 per share special dividend. This dividend will not reduce PSB’s tangible common book value for merger-adjustment purposes.
