The accompanying Notice of Annual Meeting of Stockholders and this Proxy Statement are first being mailed to stockholders on or about October 16, 2024.

REVOCATION OF PROXIES

Stockholders who execute proxies in the form solicited hereby retain the right to revoke them in the manner described below. Unless so revoked, the shares represented by such proxies will be voted at the annual meeting and all adjournments thereof. Proxies solicited on behalf of the Board of Directors of Marathon Bancorp, Inc. will be voted in accordance with the directions given thereon. Please sign and return your proxy card in the postage paid envelope provided.

The presence at the annual meeting of any stockholder who had given a proxy shall not revoke such proxy unless the stockholder delivers his or her ballot in person at the annual meeting or delivers a written revocation to our Corporate Secretary prior to the voting of such proxy.

If you have any questions about giving your proxy or require assistance, please call Julie D’Acquisto, Corporate Secretary, at (715) 845-7331.

If you are a stockholder whose shares are not registered in your name, you will need appropriate documentation from your record holder to vote in person at the annual meeting.

SOLICITATION OF PROXIES; EXPENSES

We will pay the cost of this proxy solicitation. Our directors, executive officers and other employees may solicit proxies by mail, personally, by telephone, by press release, by facsimile transmission or by other electronic means. No additional compensation will be paid to our directors, executive officers or employees for such services. We will reimburse brokerage firms and other custodians, nominees, and fiduciaries for reasonable expenses incurred by them in sending proxy materials to the beneficial owners of our common stock.

VOTING SECURITIES AND PRINCIPAL HOLDERS

Except as otherwise noted below, holders of record of Marathon Bancorp, Inc.’s shares of common stock, par value $0.01 per share, as of the close of business on September 27, 2024 are entitled to one vote for each share then held. As of September 27, 2024, there were 2,135,412 shares of common stock issued and outstanding.

Marathon Bancorp, Inc.’s Articles of Incorporation provide that, subject to certain exceptions, record owners of Marathon Bancorp, Inc.’s common stock that is beneficially owned by a person who beneficially owns in excess of 10% of Marathon Bancorp, Inc.’s outstanding shares are not entitled to any vote in respect of the shares held in excess of the 10% limit. This restriction does not apply to Marathon MHC.

​

Principal Holders

Persons and groups who beneficially own in excess of 5% of the shares of common stock are required to file certain reports with the Securities and Exchange Commission regarding such ownership. The following table sets forth, as of September 27, 2024, the shares of common stock beneficially owned by our directors and executive officers, individually and as a group, and by each person who was known to us as the beneficial owner of more than 5% of the outstanding shares of common stock. The mailing address for each of our directors and executive officers is 500 Scott Street, Wausau, Wisconsin 54403. No director or executive officer has pledged Marathon Bancorp, Inc. common stock as collateral for a loan.

2

Quorum

The presence in person or by proxy of holders of a majority of the total number of outstanding shares of common stock entitled to vote is necessary to constitute a quorum at the annual meeting. Abstentions and broker non-votes will be counted for purposes of determining that a quorum is present. In the event there are not sufficient votes for a quorum, or to approve or ratify any matter being presented at the time of the annual meeting, the annual meeting may be adjourned in order to permit the further solicitation of proxies. However, if Marathon MHC, our majority stockholder, votes at the annual meeting, a quorum would be assured.

Votes Required

As to the election of the director, the proxy card being provided by the Board of Directors enables a stockholder to vote FOR the nominee proposed by the Board, or to WITHHOLD for the nominee being proposed.  Directors are elected by a plurality of votes cast, without regard to either broker non-votes or proxies as to which the authority to vote for a nominee being proposed is withheld.  Plurality means that an individual who receives the highest number of votes cast is elected, up to the maximum number of directors to be elected at the annual meeting.

As to the ratification of the appointment of Bonadio & Co., LLP as our independent registered public accounting firm for the year ending June 30, 2025, by checking the appropriate box, a stockholder may: (i) vote FOR the ratification; (ii) vote AGAINST the ratification; or (iii) ABSTAIN from voting on such ratification.  The ratification of this matter shall be determined by a majority of the votes cast at the annual meeting, without regard to broker non-votes or proxies marked ABSTAIN.

Management anticipates that Marathon MHC, our majority stockholder, will vote all of its shares of common stock in favor of all the matters set forth above. If Marathon MHC votes all of its shares in favor of each proposal, the approval of each proposal would be assured.

Effect of Not Casting Your Vote

If you hold your shares in “street name,” you are considered the beneficial owner of your shares and your broker, bank or other holder of record is sending these proxy materials to you. As the beneficial owner, you have the right to direct your broker, bank or other holder of record how to vote by completing a voting instruction form provided by your broker, bank or other holder of record that accompanies your proxy materials. If you hold your shares in street name, it is critical that you cast your vote if you want it to count in the election of directors. Current regulations restrict the ability of your bank, broker or other holder of record to vote your shares in the election of directors and certain other matters on a discretionary basis. Therefore, if you hold your shares in street name and you do not instruct your bank, broker or other holder of record on how to vote in the election of directors, no votes will be cast on your behalf. These are referred to as “broker non-votes.”  Your bank, broker or other holder of record, however, does continue to have discretion to vote any shares for which you do not provide instructions on how to vote on the ratification of the appointment of the independent registered public accounting firm. If you are a stockholder of record and you do not cast your vote, no votes will be cast on your behalf on any of the items of business at the annual meeting.

Participants in the Marathon Bank Employee Stock Ownership Plan or the Marathon Bank 401(k) Plan

If you participate in the Marathon Bank Employee Stock Ownership Plan (the “ESOP”), you will receive a Vote Authorization Form for the ESOP that reflects all of the shares you may direct the trustee to vote on your behalf under the ESOP. 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 proportionate interest of shares of our common stock allocated or deemed allocated to his or her account. The ESOP trustee, subject to the exercise of its fiduciary responsibilities, will vote all unallocated shares of our common stock held by the ESOP and allocated shares for which no voting instructions are received in the same proportion as shares for which it has received timely voting instructions, subject to a determination that such vote is in the best interest of ESOP participants.

In addition, participants in the Marathon Bank 401(k) Plan (“401(k) Plan”) who have assets invested in Marathon Bancorp, Inc. common stock will receive a Vote Authorization Form that allows them to direct the 401(k) Plan trustee to vote their shares held by the 401(k) Plan. If a participant does not direct the 401(k) Plan trustee as to how to vote his or her shares in the 401(k) Plan, the 401(k) Plan trustee, subject to the exercise of its fiduciary responsibilities, will vote such interest in the same proportion as it has received voting instructions from other 401(k) Plan participants. The deadline for returning your ESOP Vote Authorization Form and/or 401(k) Vote Authorization Form is Tuesday, November 12, 2024 at 5:00 p.m. Central time.

At this time, the Board of Directors knows of no reason why the nominee might be unable to serve, if elected.  Except as indicated herein, there are no arrangements or understandings between any nominee or continuing director and any other person pursuant to which such nominee or continuing director was selected.  Age information is as of June 30, 2024, and term as a director includes service with Marathon Bank.

Mr. Zillges is not considered independent because he is an executive officer of Marathon Bancorp, Inc. and Marathon Bank. In determining the independence of our directors, the board of directors considered relationships between Marathon Bank and our directors that are not required to be reported under “—Transactions With Certain Related Persons,” below, consisting of deposit accounts and loans that our directors maintain at Marathon Bank.

Board Leadership Structure and Risk Oversight

The Board of Directors currently separates the positions of Chairwoman of the Board and Chief Executive Officer. Our Board of Directors is chaired by Amy Zientara, who is an independent director. This ensures a greater role for the independent directors in the oversight of Marathon Bancorp, Inc. and Marathon Bank and active participation of the independent directors in setting agendas and establishing priorities and procedures for the work of the Board. To assure effective independent oversight, the Board has adopted a number of governance practices, including holding executive sessions of the independent directors at least twice a year or more often as needed. In addition, the Compensation Committee, which consists only of independent directors, evaluates the performance of our President and Chief Executive Officer. The Board of Directors recognizes that, depending on the circumstances, other leadership models might be appropriate. Accordingly, the Board of Directors periodically reviews its leadership structure.

The Board of Directors is actively involved in oversight of risks that could affect Marathon Bancorp, Inc. This oversight is conducted primarily through committees of the Board of Directors, but the full Board of Directors has retained responsibility for general oversight of risks. The Board of Directors also satisfies this responsibility through reports by the committee chair of all board committees regarding the committees’ considerations and actions, through review of minutes of committee meetings and through regular reports directly from officers responsible for oversight of particular risks within Marathon Bancorp, Inc. Risks relating to the direct operations of Marathon Bank are further overseen by the Board of Directors of Marathon Bank, all of whom are the same individuals who serve on the Board of Directors of Marathon Bancorp, Inc. The Board of Directors of Marathon Bank also has additional committees that conduct risk oversight. All committees are responsible for the establishment of policies that guide management and staff in the day-to-day operation of Marathon Bancorp, Inc. and Marathon Bank such as lending, risk management, asset/liability management, investment management and others.

References to our Website Address

References to our website address throughout this proxy statement and the accompanying materials are for informational purposes only, or to fulfill specific disclosure requirements of the Securities and Exchange Commission’s rules. These references are not intended to, and do not, incorporate the contents of our website by reference into this proxy statement or the accompanying materials.

Delinquent Section 16(a) Reports

Our executive officers and directors and beneficial owners of greater than 10% of the outstanding shares of common stock are required to file reports with the Securities and Exchange Commission disclosing beneficial ownership and changes in beneficial ownership of our common stock. Securities and Exchange Commission rules require disclosure if an executive officer, director or 10% beneficial owner fails to file these reports on a timely basis. Based on our review of ownership reports required to be filed for the year ended June 30, 2024, we believe that no executive officer, director or 10% beneficial owner of our shares of common stock failed to file ownership reports on a timely basis with the exception of one late Form 4 filing for one transaction for each of Nicholas Zillges, Nora Spatz, Michelle Knopf,  Joy Selting-Buchberger and Terry Cornish.

Code of Ethics for Senior Officers

Marathon Bancorp, Inc. has adopted a Code of Ethics for Senior Officers that applies to Marathon Bancorp, Inc.’s principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions.

Amendments to and waivers from the Code of Ethics for Senior Officers will also be disclosed on our website.

Anti-Hedging Policy

Marathon Bancorp, Inc.’s anti-hedging and anti-pledging provisions are covered in its Insider Trading Policy. Under the policy, directors and executive officers are prohibited from engaging in short sales of Marathon Bancorp, Inc. stock, and unless specifically approved by the Board of Directors, from engaging in transactions in publicly-traded options,

7

such as puts, calls and other derivative securities based on Marathon Bancorp, Inc. stock including any hedging, monetization or similar transactions designed to decrease the risks associated with holding Marathon Bancorp, Inc. stock. The Board of Directors has not approved and does not intend to approve such a program. In addition, directors and executive officers are generally prohibited from pledging Marathon Bancorp, Inc. stock as collateral for any loan or holding Marathon Bancorp, Inc. stock in a margin account. The Board of Directors may approve an exception to this policy for a pledge of Marathon Bancorp, Inc. stock as collateral for a loan from a third party (not including margin debt) where the borrower clearly demonstrates the financial capacity to repay the loan without resort to the pledged securities. The Board of Directors has not approved any such exception to its policy.

Attendance at Annual Meetings of Stockholders

Marathon Bancorp, Inc. does not have a written policy regarding director attendance at annual meetings of stockholders, although directors are expected to attend these meetings absent unavoidable scheduling conflicts. Five members of Marathon Bancorp, Inc.’s Board of Directors attended the 2023 Annual Meeting of Stockholders.

Communications with the Board of Directors

Any stockholder who wishes to contact our Board of Directors or an individual director may do so by writing to: Marathon Bancorp, Inc., 500 Scott Street, Wausau, Wisconsin 54403, Attention: Board of Directors. The letter should indicate that the sender is a stockholder and, if shares are not held of record, should include appropriate evidence of stock ownership. Communications are reviewed by the Corporate Secretary and are then distributed to the Board of Directors or the individual director, as appropriate, depending on the facts and circumstances outlined in the communications received. The Corporate Secretary may attempt to handle an inquiry directly (for example, where it is a request for information about Marathon Bancorp, Inc. or it is a stock-related matter). The Corporate Secretary has the authority not to forward a communication if it is primarily commercial in nature, relates to an improper or irrelevant topic, or is unduly hostile, threatening, illegal or otherwise inappropriate. At each Board of Directors meeting, the Corporate Secretary shall present a summary of all communications received since the last meeting that were not forwarded and make those communications available to the Directors on request.

Meetings and Committees of the Board of Directors

The business of Marathon Bancorp, Inc. is conducted at regular and special meetings of the Board of Directors and its committees. In addition, the “independent” members of the Board of Directors (as defined in the listing standards of the Nasdaq Stock Market) meet in executive sessions. The standing committees of the Board of Directors of Marathon Bancorp, Inc. are the Audit Committee and the Compensation Committee.

The Board of Directors of Marathon Bancorp, Inc. held 10 regular meetings during the year ended June 30, 2024. Marathon Bank held 12 regular meetings and no special meetings during the year ended June 30, 2024. No member of the Board of Directors or any committee thereof attended fewer than 75% of the aggregate of: (i) the total number of meetings of the Board of Directors (held during the period for which he or she has been a director); and (ii) the total number of meetings held by all committees on which he or she served (during the periods that he or she served).

Audit Committee. The Audit Committee is comprised of Directors Grimm, Werth, Wimmer and Zientara, each of whom is “independent” in accordance with applicable Securities and Exchange Commission rules and Nasdaq listing standards.  Director Zientara serves as chair of the Audit Committee. The Board of Directors has determined that Director Grimm qualifies as an “audit committee financial expert” as defined under applicable Securities and Exchange Commission rules. The Audit Committee met 12 times during the year ended June 30, 2024.

The Audit Committee meets periodically with the independent registered public accounting firm and management to review accounting, auditing, internal control structure and financial reporting matters. The committee also receives and reviews the reports and findings and other information presented to them by Marathon Bancorp, Inc.’s officers regarding financial reporting policies and practices. The Audit Committee also reviews the performance of Marathon Bancorp, Inc.’s independent registered public accounting firm, the internal audit function and oversees policies associated with financial risk assessment and risk management. The Audit Committee selects the independent registered public accounting firm and

8

meets with them to discuss the results of the annual audit and any related matters. Our Board of Directors has adopted a written charter for the Audit Committee, which is available on our website at marathonbancorp.com/governance.

Compensation Committee. The Compensation Committee is comprised of Directors Grimm, Werth, Wimmer and Zientara. Director Zientara serves as chair of the Compensation Committee.  No member of the Compensation Committee is a current or former officer or employee of Marathon Bancorp, Inc. or Marathon Bank.  The Compensation Committee met two times during the year ended June 30, 2024.

The Compensation Committee is responsible for establishing the compensation philosophy, developing compensation guidelines, establishing (or recommending to the entire Board of Directors) the compensation of the Chief Executive Officer and the other executive officers. No executive officer who is also a director participates with respect to decisions on his or her compensation.

During the year ended June 30, 2024, the Compensation Committee did not utilize the services of a compensation consultant.

The Compensation Committee operates under a written charter which is available on our website at marathonbancorp.com/governance. This charter sets forth the responsibilities of the Compensation Committee and reflects the Compensation Committee’s commitment to create a compensation structure that not only compensates senior management but also aligns the interests of senior management with those of our stockholders.

Our goal is to determine appropriate compensation levels that will enable us to meet the following objectives:

The Compensation Committee considers a number of factors in their decisions regarding executive compensation, including, but not limited to, the level of responsibility and performance of the individual executive officers, the overall performance of Marathon Bancorp, Inc. and a peer group analysis of compensation paid at institutions of comparable size and complexity. The Compensation Committee also considers the recommendations of the Chief Executive Officer with respect to the compensation of executive officers other than the Chief Executive Officer.

The base salary levels for our executive officers are set to reflect the duties and levels of responsibilities inherent in the position and to reflect competitive conditions in the banking business in Marathon Bancorp, Inc.’s market area. Comparative salaries paid by other financial institutions are considered in establishing the salary for our executive officers. The Compensation Committee has utilized bank compensation surveys compiled by the American Bankers Association. In setting the base salaries, the Compensation Committee also considers a number of factors relating to the executive officers, including individual performance, job responsibilities, experience level, ability and knowledge of the position. These factors are considered subjectively and none of the factors are accorded a specific weight.

Nominating Procedures. The Board of Directors of Marathon Bancorp, Inc. has not established a separate standing Nominating Committee. Instead, nominations for director must be approved by a majority of the Board of Directors. The Board of Directors believes that it is the responsibility of the entire Board of Directors to participate in the identification, evaluation, recruitment and selection of qualified directors and, therefore, has not delegated this function to a committee of the Board. Marathon Bancorp, Inc. would qualify for Nasdaq’s “Controlled Company Exemption” from

9

the independence requirements with respect to nominating committees for companies with majority stockholders because more than 50% of Marathon Bancorp, Inc.’s shares of common stock are owned by Marathon MHC. The Board of Directors, acting as the Nominating Committee, met one time during the year ended June 30, 2024.

The Board of Directors does not have a formal policy or specific guidelines regarding diversity among board members. However, the Board of Directors seeks members who represent a mix of backgrounds that will reflect the diversity of our stockholders, employees, and customers, and experiences that will enhance the quality of the Board of Directors’ deliberations and decisions. As the holding company for a community bank, the Board of Directors also seeks directors who can continue to strengthen Marathon Bank’s position in its community and can assist Marathon Bank with business development through business and other community contacts.

The Board of Directors considers the following criteria in evaluating and selecting candidates for nomination:

10

The Board of Directors identifies nominees by first evaluating the current members of the Board of Directors willing to continue in service, including the current members’ board and committee meeting attendance and performance, length of board service, experience and contributions, and independence. Current members of the Board of Directors with skills and experience that are relevant to Marathon Bancorp, Inc.’s business and who are willing to continue in service are considered for re-nomination, balancing the value of continuity of service by existing members of the Board of Directors with that of obtaining a new perspective. If there is a vacancy on the Board of Directors because any member of the Board of Directors does not wish to continue in service or if the Board of Directors decides not to re-nominate a member for re-election, the Board of Directors would determine the desired skills and experience of a new nominee (including a review of the skills set forth above), may solicit suggestions for director candidates from all board members and may engage in other search activities.

During the year ended June 30, 2024 we did not pay a fee to any third party to identify or evaluate or assist in identifying or evaluating potential nominees for director.

The Board of Directors may consider qualified candidates for director suggested by our stockholders. Stockholders can suggest qualified candidates for director by writing to our Corporate Secretary at 500 Scott Street, Wausau, Wisconsin 54403. The Board of Directors has adopted a procedure by which stockholders may recommend nominees to the Board of Directors. Stockholders who wish to recommend a nominee must write to Marathon Bancorp, Inc.’s Corporate Secretary and such communication must include:

11

To be timely, the submission of a candidate for director by a stockholder must be received by the Corporate Secretary at least 120 days prior to the anniversary date of the proxy statement relating to the preceding year’s annual meeting of stockholders. If (i) less than 90 days’ prior public disclosure of the date of the meeting is given to stockholders and (ii) the date of the annual meeting is advanced more than 30 days prior to or delayed more than 30 days after the anniversary of the preceding year’s annual meeting, a stockholder’s submission of a candidate shall be timely if delivered or mailed to and received by the Corporate Secretary of Marathon Bancorp, Inc. no later than the 10^th day following the day on which public disclosure (by press release issued through a nationally recognized news service, a document filed with the Securities and Exchange Commission, or on a website maintained by Marathon Bancorp, Inc.) of the date of the annual meeting is first made.

Submissions that are received and that satisfy the above requirements are forwarded to the Board of Directors for further review and consideration, using the same criteria to evaluate the candidate as it uses for evaluating other candidates that it considers.

There is a difference between the recommendations of nominees by stockholders pursuant to this policy and a formal nomination (whether by proxy solicitation or in person at a meeting) by a stockholder. Stockholders have certain rights under applicable law with respect to nominations, and any such nominations must comply with applicable law and provisions of the Bylaws of Marathon Bancorp, Inc. See “Stockholder Proposals and Nominations.”

Transactions With Certain Related Persons

Section 402 of the Sarbanes-Oxley Act of 2002 generally prohibits an issuer from: (1) extending or maintaining credit; (2) arranging for the extension of credit; or (3) renewing an extension of credit in the form of a personal loan for an officer or director. There are several exceptions to this general prohibition, one of which is applicable to Marathon Bank. The Sarbanes-Oxley Act does not apply to loans made by a depository institution that is insured by the Federal Deposit Insurance Corporation and is subject to the insider lending restrictions of the Federal Reserve Act. All loans to Marathon Bank’s directors and officers are made in conformity with the Federal Reserve Act and applicable regulations.

All loans made by Marathon Bank to executive officers, directors, immediate family members of executive officers and directors, or organizations with which executive officers and directors are affiliated, were made in the ordinary course of business, on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable loans to persons not related to Marathon Bank, and did not involve more than the normal risk of collectability or present other unfavorable features. Marathon Bank is in compliance with federal regulations with respect to its loans and extensions of credit to executive officers and directors. We did not have any outstanding loans to our executive officers and directors at June 30, 2024. We have not had any transaction or series of transactions, or business relationships, nor are any such transactions or relationships proposed, in which the amount involved exceeds $120,000 and in which our directors or executive officers have a direct or indirect material interest.

Pursuant to our Policy and Procedures for Approval of Related Person Transactions, the Audit Committee periodically reviews, no less frequently than twice a year, a summary of transactions in excess of $25,000 with our directors, executive officers, and their family members, for the purpose of determining whether the transactions are within our policies and should be ratified and approved. Additionally, pursuant to our Code of Business Conduct and Ethics, all of our executive officers and directors must disclose any personal or financial interest in any matter that comes before Marathon Bancorp, Inc.

Executive Compensation

Summary Compensation Table. The table below summarizes the total compensation paid to or earned by our President and Chief Executive Officer and our two other most highly compensated executive officers for the year ended June 30, 2024. Each individual listed in the table below is referred to as a “named executive officer.”

​

Outstanding Equity Awards at Year End. The following table sets forth information with respect to outstanding equity awards as of June 30, 2024 for the named executive officers. All equity awards reflected in this table were granted pursuant to our 2022 Equity Incentive Plan, described below.

2022 Equity Incentive Plan.  Marathon Bancorp, Inc. has adopted the Marathon Bancorp, Inc. 2022 Equity Incentive Plan (“Equity Plan”), which was approved by stockholders in May 2022. Employees and directors of Marathon Bancorp, Inc., Marathon Bank and their subsidiaries are eligible to receive awards under the Equity Plan, except that non-employees may not be granted incentive stock options. Subject to permitted adjustments for certain corporate transactions, the Equity Plan authorizes the issuance or delivery to participants of up to 152,943 shares of Marathon Bancorp, Inc. common stock pursuant to grants of incentive and non-qualified stock options, restricted stock awards and restricted stock units. Of this number, the maximum number of shares of Marathon Bancorp, Inc. common stock that may be issued under the Equity Plan pursuant to the exercise of stock options is 109,245 shares, and the maximum number of shares of Marathon Bancorp, Inc. common stock that may be issued as restricted stock awards or restricted stock units is 43,698 shares. A total of 43,405 restricted stock shares and 104,877 stock options were awarded by the Compensation Committee under the Equity Plan as of June 30, 2024. The stock option and restricted stock awards granted to named executive officers and directors will vest 20% each year over a five-year period. Notwithstanding the foregoing, the vesting of these awards would accelerate upon death, disability or involuntary termination of employment on or following a change in control.

Agreements and Benefit Plans

Employment Agreement with Nicholas W. Zillges. On April 14, 2021, Marathon Bank, the wholly owned subsidiary of Marathon Bancorp, Inc., entered into an employment agreement with Nicholas W. Zillges, President and Chief Executive Officer. The term of the employment agreement is for three years, which automatically extends for an additional year on January 1 of each year unless either Marathon Bank or Mr. Zillges give notice no later than 30 days before the renewal date that the term will not be renewed.

The employment agreement specifies Mr. Zillges’ base salary, which the Compensation Committee may increase, but not decrease. Beginning January 1, 2024, Mr. Zillges’ base salary will increase automatically at a minimum 5% per year.  In addition, the employment agreement provides that Mr. Zillges will be eligible to participate in any bonus plan or arrangement of Marathon Bank in which senior management is eligible to participate and/or may receive a bonus on a discretionary basis, as determined by the Compensation Committee. Specifically, Mr. Zillges will be eligible to participate in Marathon Bank’s short-term bonus program, pursuant to which he will be entitled to a target bonus opportunity equal to at least 50% of base salary. Mr. Zillges is also entitled to participate in all employee benefit plans, arrangements and

15

perquisites offered to employees and officers of Marathon Bank and the reimbursement of reasonable travel and other business expenses incurred in the performance of his duties with Marathon Bank, including use of bank-owned country club membership available to executive officers and reimbursement of expenditures primarily related to business travel from our headquarters to Milwaukee, such as automobile expenses, for which Mr. Zillges is reimbursed $1,500 per month, and lodging.

Marathon Bank may terminate Mr. Zillges’ employment, or Mr. Zillges may resign, at any time with or without good reason. In the event of Mr. Zillges’ termination without cause (other than due to death or disability) or voluntary resignation for good reason (a “qualifying termination”), Marathon Bank would pay Mr. Zillges a gross severance payment equal to two times the sum of his base salary and highest target bonus opportunity during the three most recently completed performance periods prior to his date of termination. One-half of the gross severance payment would be paid in a cash lump sum payment within 60 days of the date of termination, and the remaining one-half of the gross severance payment would be payable in equal installments for 24 months in accordance with the regular payroll practices of Marathon Bank.  In addition, Mr. Zillges would receive up to 12 monthly COBRA premium reimbursement payments, including a tax-gross up payment to ensure the full amount of the reimbursement payment would have been received if it had not been taxable, to the extent COBRA coverage is elected.

In the event of Mr. Zillges’ qualifying termination on or within two years after the effective time of a change in control of Marathon Bancorp, Inc. or Marathon Bank, he would be entitled to (in lieu of the payments and benefits described in the previous paragraph) a gross cash severance payment equal to three times the sum of his base salary as of his date of termination (or immediately prior to the change in control, if higher) and highest target bonus opportunity in any of the three most recently completed performance periods prior to the change in control, payable in a lump sum within 60 days of the date of termination.  In addition, Mr. Zillges would receive up to 18 monthly COBRA premium reimbursement payments, including a tax-gross up payment to ensure the full amount of the reimbursement payment would have been received if it had not been taxable, to the extent COBRA coverage is elected.

Upon termination of employment (other than a termination on or after a change in control), Mr. Zillges will be required to adhere to one-year non-competition and non-solicitation restrictions set forth in his employment agreement.

Change in Control Agreements. Marathon Bank entered into individual change in control agreements with its four other executive officers, including Joy Selting-Buchberger, Senior Vice President and Chief Financial Officer, and Michelle Knopf, Executive Vice President and Director of Mortgage Services.  The change in control agreements have one-year terms that automatically renew for an additional year on January 1 of each year unless either Marathon Bank or the executive gives notice no later than 60 days before such renewal date that term will not be renewed.  Notwithstanding the foregoing, if Marathon Bancorp, Inc. or Marathon Bank enters into a transaction that would be considered a change in control as defined under the agreements, the term of the agreements would extend automatically so that they would expire no less than one year beyond the effective date of the change in control.

In the event of the executive’s involuntary termination of employment (other than for cause, disability or death) or voluntary resignation for “good reason” on or after the effective date of a change in control of Marathon Bancorp, Inc. or Marathon Bank, each executive would be entitled to a severance payment equal to one times the sum of the executive’s base salary in effect as of the date of termination (or immediately prior to the change in control, if higher) and the highest target bonus opportunity in any of the three most recently completed performance periods prior to the change in control. Such payment is payable in a lump sum within 30 days following the executive’s date of termination. In addition, each executive would receive up to 12 monthly COBRA premium reimbursement payments, including a tax-gross up payment to ensure the full amount of the reimbursement payment would have been received if it had not been taxable, to the extent COBRA coverage is elected.

The conversion of Marathon MHC from mutual to stock form and a contemporaneous stock offering of a newly formed stock holding company is not considered a change in control for purposes of the employment agreement and change in control agreements described above.

16

Bonus Program. During the year ended June 30, 2024, Mr. Zillges did not receive a bonus while Marathon Bank awarded discretionary bonuses of $5,000 to each of Ms. Selting-Buchberger and Ms. Knopf in recognition of their individual responsibilities and contributions to our successful operations.

401(k) Plan. Marathon Bank maintains the Marathon Bank Retirement Savings Plan, a tax-qualified defined contribution plan for eligible employees (the “401(k) Plan”).  The named executive officers are eligible to participate in the 401(k) Plan just like other employees.  An employee is eligible to enter the plan on January 1^st, April 1^st, July 1^st, or October 1^st following their date of employment; provided the employee is at least 19 years of age.

Under the 401(k) Plan a participant may elect to defer, on a pre-tax basis, the maximum amount as permitted by the Internal Revenue Code.  For 2024, the salary deferral contribution limit is $23,000, provided, however, that a participant over age 50 may contribute an additional $7,500 to the 401(k) Plan for a total of $30,500.  A participant is always 100% vested in his or her salary deferral contributions.  Marathon Bank also currently provides participants with matching contributions and a safe harbor profit sharing contribution to active participants in the 401(k) plan. Marathon Bank has established an employer stock fund in the 401(k) Plan so that participants can acquire an interest in the common stock of Marathon Bancorp, Inc. through their accounts in the 401(k) Plan. Expense recognized in connection with the 401(k) Plan totaled $150,899, which includes $26,546 for plan administration and $124,353 in matching/safe harbor contributions for the year ended June 30, 2024.

Employee Stock Ownership Plan. Marathon Bank maintains an employee stock ownership plan (the “ESOP”) for eligible employees.  The named executive officers are eligible to participate in the ESOP just like other eligible employees.  Eligible employees who have attained age 21 on the first entry date commencing on or after the eligible employee’s completion of one year of service.

The ESOP trustee purchased, on behalf of the ESOP, 87,397 shares of Marathon Bancorp, Inc. common stock outstanding, funded with a loan from Marathon Bancorp, Inc. equal to the aggregate purchase price of the common stock.  The loan is repaid principally through Marathon Bank’ discretionary contributions to the ESOP and any dividends payable on common stock held by the ESOP over the 25-year term of the loan.  The trustee holds the shares purchased by the ESOP plan in an unallocated suspense account. Shares are released from the suspense account as we repay the loan and are allocated to participants’ accounts on the basis of each participant’s proportional share of plan compensation relative to all participants.  A participant becomes 100% vested in his or her account balance after three years of service.  Participants also will become fully vested automatically upon normal retirement, death or disability, a change in control, or termination of the ESOP.  Generally, participants will receive distributions from the ESOP upon separation from service in accordance with the terms of the plan document.  The ESOP reallocates any unvested shares forfeited upon termination of employment among the remaining participants.

Directors’ Compensation

The following table sets forth for the year ended June 30, 2024 certain information as to the total remuneration we paid to our directors. Mr. Zillges did not receive director fees for the year ended June 30, 2024.

17

Director Fees

Non-employee directors of Marathon Bank are currently paid $2,000 per month as a director. Each non-employee director also received a $100 bonus cash payment during fiscal 2024. No additional fees are paid for attending committee meetings.

Each person who serves as a director of Marathon Bank also serves as a director of Marathon Bancorp, Inc. and will initially earn a monthly fee only in his or her capacity as a board member of Marathon Bank.

2022 Equity Incentive Plan. Our directors are eligible to participate in the Equity Plan and received grants in 2022. The Equity Plan is described under “Executive Compensation—2022 Equity Incentive Plan” above.

PROPOSAL II—RATIFICATION OF APPOINTMENT OF

INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Audit Committee of Marathon Bancorp, Inc. has approved the engagement of Bonadio & Co., LLP to be our independent registered public accounting firm for the year ending June 30, 2025, subject to the ratification of the engagement by our stockholders. At the annual meeting, stockholders will consider and vote on the ratification of the Audit Committee’s engagement of Bonadio & Co., LLP for the year ending June 30, 2025. A representative of Bonadio & Co., LLP is expected to be present at the annual meeting via telephone and may respond to appropriate questions and make a statement if he or she so desires.

Even if the engagement of Bonadio & Co., LLP is ratified, the Audit Committee, in its discretion, may direct the appointment of a different independent registered public accounting firm at any time during the year if it determines that such change would be in the best interests of Marathon Bancorp, Inc. and its stockholders.

Set forth below is certain information concerning aggregate fees billed for professional services rendered by Bonadio & Co., LLP during the years ended June 30, 2024 and 2023.

​

Audit Fees. Audit Fees include the aggregate fees billed for each of the last two fiscal years for professional services rendered for the audit of our annual financial statements and review of financial statements included in our Form 10-Q or services that are normally provided in connection with statutory and regulatory filings or engagements for those fiscal years.

The Audit Committee has considered whether the provision of non-audit services is compatible with maintaining the independence of Bonadio & Co., LLP. The Audit Committee concluded that performing such services does not affect the independence of Bonadio & Co., LLP in performing its function as our independent registered public accounting firm.

The Audit Committee’s current policy is to pre-approve all audit and non-audit services provided by the independent registered public accounting firm, either by approving an engagement prior to the engagement or pursuant to a pre-approval policy with respect to particular services, subject to the de minimus exceptions for non-audit services described in Section 10A(i)(1)(B) of the Securities Exchange Act of 1934, as amended. These services may include audit services, audit-related services, tax services and other services.  The Audit Committee may delegate pre-approval authority to one or more members of the Audit Committee when expedition of services is necessary.  The independent registered public accounting firm and management are required to periodically report to the full Audit Committee regarding the extent of services provided by the independent registered public accounting firm in accordance with this pre-approval, and the fees for the services performed to date.  The Audit Committee pre-approved 100% of audit fees billed and paid during the fiscal years ended June 30, 2024 and 2023, as indicated in the table above.

The Board of Directors recommends a vote “FOR” the ratification of Bonadio & Co., LLP as independent registered public accounting firm for the year ending June 30, 2025.
