PROXY STATEMENT FOR SPECIAL MEETING OF STOCKHOLDERS GENERAL INFORMATION This proxy statement is furnished in connection with the solicitation of proxies by the board of directors of Home Bancorp Wisconsin, Inc. (“Home Bancorp”), to be used at the special meeting of stockholders of Home Bancorp, and any postponements or adjournments of the special meeting (the “special meeting”). The special meeting will be held at the Home Savings Bank office located at 3762 East Washington Avenue, Madison, Wisconsin 53704 on March 8, 2022, at 2:30 p.m., local time, for the purpose of considering and voting on the proposals that must be approved for Home Bancorp to complete the Sale Transaction (as defined below) with Dupaco Community Credit Union (“Dupaco”). On September 30, 2021, Dupaco, Home Bancorp, and Home Savings Bank entered into a Purchase and Assumption Agreement (the “P&A Agreement”) pursuant to which Dupaco will purchase substantially all of Home Savings Bank’s assets and assume substantially all Home Savings Bank’s liabilities (including all of the deposit liabilities) (the “Bank Asset Sale”). The Bank Asset Sale is an integral part of a larger transaction contemplated by the P&A Agreement in which, as soon as practicable following the Bank Asset Sale, Home Savings Bank will liquidate and distribute all of its remaining assets to Home Bancorp pursuant to Home Savings Bank’s Plan of Voluntary Liquidation (the “Bank Liquidation”) and thereafter Home Bancorp will dissolve, wind up its operations and distribute all of its remaining assets, including the proceeds from the Bank Asset Sale, to its stockholders pursuant to Home Bancorp’s Plan of Dissolution (the “Company Dissolution”). The Bank Asset Sale, the Bank Liquidation and the Company Dissolution are referred to as the “Sale Transaction.” COVID-19 Pandemic Considerations Due to the ongoing health concerns relating to the Coronavirus Disease 2019 (COVID-19) pandemic, and to best protect the health of our employees, stockholders and community, space at the special meeting will be limited and seating will be available on a first-come, first-served basis. We urge you to carefully evaluate the relative benefits of in-person attendance at the special meeting and to consider not attending the meeting in person. Instead, please take advantage of the ability to vote by proxy, as instructed on the proxy card or voting instructions that have been provided to you. We are actively monitoring the recommendations of public health officials in response to the continuing COVID-19 pandemic. If we decide to change the location of the special meeting or hold it partly or solely by means of virtual communications, as permitted by applicable law, we will announce such decision in advance, as promptly as practicable. If we take this step, details of how to participate will be issued by a press release which will also be posted on our website. INFORMATION ABOUT VOTING Only holders of record of Home Bancorp’s common stock as of the close of business on January 10, 2022 (the “Record Date”) are entitled to notice of and to vote at the special meeting, and are entitled one vote for each share then held. As of the close of business on the Record Date, there were 1,353,104 shares of Home Bancorp common stock outstanding and entitled to be voted. Home Bancorp’s Articles of Incorporation provide that record holders of Home Bancorp’s common stock who beneficially own more than 10% of the outstanding shares of common stock (the “Limit”) are not entitled to any vote with respect to the shares held in excess of the Limit. At the special meeting, stockholders will be asked to consider and vote upon the following proposals. The Sale Transaction cannot be completed unless Proposals One and Two are approved.

Proposal One – Approval of the P&A Agreement and the Bank Asset Sale. Stockholders will be asked to approve the P&A Agreement and the Bank Asset Sale. A stockholder may (1) vote “FOR” the proposal, (2) vote “AGAINST” the proposal or (3) “ABSTAIN” from voting on the proposal. Approval of the P&A Agreement and the Bank Asset Sale proposal requires the affirmative vote on the proposal of the holders of a majority of the shares outstanding and entitled to vote. Broker non-votes and proxies marked “Abstain” have the same effect as a vote “Against” the P&A Agreement and the Bank Asset Sale. Proposal Two – Approval of the Company Dissolution. Stockholders will be asked to approve the Company Dissolution pursuant to the Plan of Dissolution. A stockholder may (1) vote “FOR” the proposal, (2) vote “AGAINST” the proposal or (3) “ABSTAIN” from voting on the proposal. Approval of the Company Dissolution requires the affirmative vote on the proposal of the holders of a majority of the shares outstanding and entitled to vote. Broker non-votes and proxies marked “Abstain” have the same effect as a vote “Against” the Company Dissolution. Proposal Three – Approval of the Adjournment of the Special Meeting If Necessary. Stockholders will be asked to approve the adjournment of the special meeting of stockholders, if necessary, to solicit additional proxies in favor of proposals 1 or 2, or both. A stockholder may (1) vote “FOR” the proposal, (2) vote “AGAINST” the proposal or (3) “ABSTAIN” from voting on the proposal. Approval of the adjournment proposal requires the affirmative vote on the proposal of the holders of a majority of the votes cast at the special meeting. Quorum. As of the close of business on the Record Date, there were 1,353,104 shares of Home Bancorp common stock outstanding and entitled vote. The presence, in person or by proxy, of a majority of those outstanding shares of common stock entitled to vote is necessary to constitute a quorum at the special meeting. Participants in the Home Savings Bank ESOP and Home Savings Bank 401(k) Plan. If you participate in the Home Savings Bank Employee Stock Ownership Plan (the “ESOP”), or if you invest in Home Bancorp common stock through the Home Bancorp Wisconsin, Inc. Stock Fund (the “Stock Fund”) in the Home Savings Bank 401(k) Plan (the “401(k) Plan”), you will receive a vote authorization form that reflects all shares you may direct the ESOP trustee and/or the Stock Fund trustee to vote on your behalf under the respective plan. Under the terms of the ESOP, the ESOP trustee votes all shares held by the ESOP, but each ESOP participant may direct the trustee how to vote the shares of common stock allocated to his or her account. The ESOP trustee will vote all unallocated shares of Home Bancorp common stock held by the ESOP and all allocated shares for which no voting instructions are received in the same proportion as shares for which it has received timely voting instructions. Under the terms of the 401(k) Plan, a participant is entitled to provide voting instructions for all shares credited to his or her 401(k) Plan account and held in the Stock Fund. Shares for which no voting instructions are given or for which instructions were not timely received will be voted in the same proportion as shares for which voting instructions were received. The deadline for returning your voting instructions is March 1, 2022 at 4:00 p.m. Central Time. Voting by Proxy. Home Bancorp’s board of directors is sending you this proxy statement to request that you allow your shares of Home Bancorp common stock to be represented at the special meeting by the persons named as proxies on the enclosed proxy card. Stockholders who execute proxies in the form solicited hereby retain the right to revoke them in the manner described below under the heading “Revocation of Proxies.” Unless so revoked, the shares represented by such proxies will be voted at the special meeting and at any and all adjournments or postponements. Proxies solicited on behalf of the board of directors of Home Bancorp will be voted according to the directions given thereon. If you sign, date and return a proxy card without giving voting instructions, your shares will be voted as recommended by Home Bancorp’s board of directors. The board of directors unanimously recommends that you vote “FOR” the approval of the P&A Agreement and the Bank Asset Sale and “FOR” approval of the Company Dissolution. Voting by Telephone or Via the Internet. Instead of voting by mailing a proxy card, registered stockholders can vote their shares of Home Bancorp common stock by telephone or via the Internet. The telephone and Internet voting procedures are designed to authenticate stockholders’ identities, allow stockholders to provide their voting instructions and confirm that their instructions have been recorded properly. Specific instructions for telephone and internet voting are set forth on the proxy card. The deadline for voting by telephone or via the Internet is 12:00 a.m., Central Time, on March 8, 2022. 2

Voting Agreements. Each director of Home Bancorp, solely in his or her individual capacity as a stockholder of Home Bancorp, has entered into a voting agreement with Dupaco, in which the director has agreed, subject to the terms and conditions set forth in the voting agreement, to vote the shares of Home Bancorp common stock controlled solely by him or her, and use best efforts to have shares over which he or she has shared voting power voted, in favor of the P&A Agreement and the Bank Asset Sale and in favor of the Company Dissolution, as well as agreeing to certain other customary restrictions with respect to the voting and transfer of his or her shares of Home Bancorp common stock. As of the close of business on the Record Date, a total of 95,320 shares of Home Bancorp common stock, representing approximately 7.0% of the outstanding shares of Home Bancorp common stock entitled to vote at the special meeting, are subject to the voting agreements. REVOCATION OF PROXIES Proxies may be revoked by sending written notice of revocation addressed to Home Bancorp’s Secretary, Home Bancorp Wisconsin, Inc., 3762 East Washington Avenue, Madison, Wisconsin 53704, by submitting a signed later-dated proxy, by voting again by telephone or via the Internet no later than 12:00 a.m., Central Time, on March 8, 2022, or by voting in person at the special meeting. The presence of a stockholder at the special meeting, by itself, does not constitute revocation of a proxy. PROPOSAL 1 – APPROVAL OF THE P&A AGREEMENT AND THE BANK ASSET SALE The information in this proxy statement regarding the P&A Agreement, the Bank Asset Sale and the other transactions contemplated by the P&A Agreement is qualified in its entirety by reference to the full text of the P&A Agreement, which is attached as Appendix A and incorporated by reference into this proxy statement. You should read the P&A Agreement in its entirety. General As soon as practicable after the conditions to consummation of the Bank Asset Sale have been satisfied or waived, and unless the P&A Agreement has been terminated as discussed below, Home Savings Bank will sell substantially all of its assets to Dupaco and Dupaco will assume substantially all of Home Savings Bank’s liabilities (including all deposit liabilities) for 45.5 million in cash, subject to possible downward adjustment as described under the heading “—Consideration to be Received by Stockholders.” The Bank Asset Sale is the first integral step in the Sale Transaction contemplated by the P&A Agreement. The Sale Transaction consists of (i) the Bank Asset Sale, (ii) the Bank Liquidation, including the distribution of Home Savings Bank’s remaining assets to Home Bancorp pursuant to a Plan of Voluntary Liquidation, and (iii) the Company Dissolution, including the distribution of Home Bancorp’s remaining assets to Home Bancorp stockholders pursuant to Home Bancorp’s Plan of Dissolution. If the Sale Transaction is completed, Home Bancorp estimates that stockholders would receive between 26.47 and 27.25 in cash for each share of Home Bancorp common stock that they own. This estimated consideration per share is based on numerous assumptions and is subject to change based on several factors that are discussed under the heading “– Consideration to be Received by Stockholders.” You should read the description under that heading, as well as the remainder of this proxy statement, before voting on the Sale Transaction. Further, in addition to the factors that could affect the consideration received by stockholders of which Home Bancorp is currently aware, in the course of the sale and dissolution process, unanticipated expenses and liabilities will arise, and such unanticipated expenses and liabilities may reduce the amount of cash available for distribution to stockholders. Accordingly, stockholders should not assume that the ultimate per share consideration distributed to them will be within the estimated range of 26.47 to 27.25 per share. In addition to stockholder approval, completing the Bank Asset Sale and the Sale Transaction requires approval from the Federal Deposit Insurance Corporation (the “FDIC”), the Wisconsin Department of Financial Institutions (the “WDFI”), the National Credit Union Administration (the “NCUA”), the Iowa Division of Credit Unions (“IDCU”), and, with respect to deregistration of Home Bancorp as a bank holding company in connection with its dissolution, the Board of Governors of the Federal Reserve System (the “FRB”). Further, Home Savings Bank must comply with WDFI and FDIC ru

local time. At the special meeting, Home Bancorp's stockholders will consider and vote on proposals that must be approved for Home Bancorp to complete the Sale Transaction (as defined below) with Dupaco Community Credit Union ("Dupaco").
