IF Bancorp, Inc.

Proxy Statement

This proxy statement is furnished in connection with the solicitation of proxies by the Board of Directors of IF Bancorp, Inc. (the “Company” or “IF Bancorp”) to be used at the annual meeting of stockholders of the Company. The Company is the holding company for Iroquois Federal Savings and Loan Association (the “Association” or “Iroquois Federal”). The annual meeting will be held at the Association’s administrative office located at 204 East Cherry Street, Watseka, Illinois 60970 on Monday, November 19, 2018 at 2:00 p.m. local time. The notice of annual meeting of stockholders and this proxy statement are first being made available to stockholders on or about October 15, 2018.

Voting and Proxy Procedure

Who Can Vote

You are entitled to vote your Company common stock if the records of the Company show that you held your shares as of the close of business on September 25, 2018. If your shares are held through a broker, bank or other holder of record, you are considered the beneficial owner of shares held in “street name” and you will receive instructions directly from your broker, bank or other holder of record in order to vote your shares. Your holder of record may allow you to provide voting instructions by telephone or by the Internet.

As of the close of business on September 25, 2018, there were 3,871,408 shares of Company common stock outstanding. Each share of common stock has one vote. The Company’s Articles of Incorporation provide that record owners of Company common stock beneficially owned by a person who beneficially owns in excess of 10% of the Company’s outstanding common stock (a “10% beneficial owner”), shall not be entitled to vote, in the aggregate, shares beneficially owned by the 10% beneficial owner in excess of 10% of the Company’s outstanding common stock, unless a majority of unaffiliated directors (as defined in the articles of incorporation) grant such entitlement by resolution in advance of the acquisition of the excess shares.

Attending the Meeting

If you were a stockholder as of the close of business on September 25, 2018, you may attend the meeting. However, if your shares of Company common stock are held in street name, you will need proof of ownership to be admitted to the meeting. A recent brokerage statement or a letter from a bank or broker are examples of proof of ownership. If you want to vote your shares of Company common stock held in street name in person at the meeting, you will have to get a written proxy in your name from the broker, bank or other holder of record who holds your shares.

Quorum and Vote Required for Proposals

Quorum. A majority of the outstanding shares of common stock entitled to vote is required to be represented at the meeting to constitute a quorum for the transaction of business.

Votes Required for Proposals. At this year’s annual meeting, stockholders will elect three directors to serve for a term of three years and until their successors are elected and qualified. In voting on the election of directors, you may vote in favor of the nominees, withhold votes as to all nominees, or withhold votes as to specific nominees. There is no cumulative voting for the election of directors. Directors must be elected by a plurality of the votes cast at the annual meeting. This means that the nominees receiving the greatest number of votes will be elected.

In voting on the ratification of the appointment of BKD, LLP as the Company’s independent registered public accounting firm, you may vote in favor of the proposal, vote against the proposal or abstain from voting. To ratify the selection of BKD, LLP as our independent registered public accounting firm for fiscal 2019, the affirmative vote of a majority of the votes cast on the proposal is required.

In voting on the advisory, non-binding proposal to approve the executive compensation described in this proxy statement, you may vote in favor of the advisory proposal, vote against the advisory proposal or abstain from voting. Approval of this proposal requires the affirmative vote of a majority of the votes cast on the proposal. While this vote is required by law, it will neither be binding on the Board of Directors, nor will it create or imply any change in the fiduciary duties of or impose any additional fiduciary duty on the Board of Directors.

Broker Non-Votes. If you do not provide your broker or other record holder with voting instructions on certain non-routine matters, your broker will not have discretion to vote your shares on such matters. The election of directors and the advisory non-binding proposal to approve the executive compensation described in this proxy statement are non-routine matters. In the case of routine matters (e.g., the ratification of the independent auditors), your broker or other holder of record is permitted to vote your shares in the record holder’s discretion if you have not provided voting instructions. A “broker non-vote” occurs when your broker submits a proxy for the meeting with respect to routine matters, but does not vote on non-routine matters because you did not provide voting instructions on such matters.

How Votes Are Counted. If you return valid proxy instructions or attend the meeting in person, we will count your shares for purposes of determining whether there is a quorum, even if you abstain from voting. Broker non-votes also will be counted for purposes of determining the existence of a quorum.

In counting votes for the election of directors, votes that are withheld and broker non-votes will have no effect on the outcome of the election.

In counting votes on the proposal to ratify the selection of the independent registered public accountants, abstentions will have no effect on the outcome of the vote.

In counting votes on the approval of the non-binding proposal to approve the executive compensation described in this proxy statement, abstentions and broker non-votes will have no effect on the outcome of the vote.

Voting by Proxy

The Company’s Board of Directors is providing you this proxy statement to request that you allow your shares of Company common stock to be represented at the annual meeting by the persons named in the enclosed proxy card. All shares of Company common stock represented at the meeting by properly executed and dated proxies will be voted according to the instructions indicated on the proxy card. If you sign, date and return a proxy card without giving voting instructions, your shares will be voted as recommended by the Company’s Board of Directors.

2

The Board of Directors recommends that you vote:

If any matters not described in this proxy statement are properly presented at the annual meeting, the persons named in the proxy card will use their judgment to determine how to vote your shares. This includes a motion to adjourn or postpone the meeting to solicit additional proxies. If the annual meeting is postponed or adjourned for less than 30 days, your Company common stock may be voted by the persons named in the proxy card on the new meeting date, provided you have not revoked your proxy. The Company does not currently know of any other matters to be presented at the meeting.

You may revoke your proxy at any time before the vote is taken at the meeting. To revoke your proxy, you must advise the Corporate Secretary of the Company in writing before your common stock has been voted at the annual meeting, deliver a later dated proxy or attend the meeting and vote your shares in person by ballot. Attendance at the annual meeting will not in itself constitute revocation of your proxy.

Participants in the Iroquois Federal Savings and Loan Association ESOP or 401(k) Plan

If you participate in the Iroquois Federal Savings and Loan Association Employee Stock Ownership Plan (the “ESOP”), you will receive a vote authorization form for the plan that reflects all shares you may direct the trustees 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 shares of common stock allocated to his or her account. The ESOP trustee, subject to the exercise of its fiduciary responsibilities, will vote all unallocated shares of IF Bancorp 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. Under the terms of the 401(k) Plan, a participant is entitled to vote the shares credited to his or her 401(k) Plan account. Shares for which no voting instructions are given or for which instructions were not timely received may be voted by the 401(k) Plan trustee in the same proportion as shares for which voting instructions were received. The deadline for returning your ESOP voting instructions is Monday, November 12, 2018.

Corporate Governance

General

The Company periodically reviews its corporate governance policies and procedures to ensure that the Company meets the highest standards of ethical conduct, reports results with accuracy and transparency and maintains full compliance with the laws, rules and regulations that govern the Company’s operations. As part of this periodic corporate governance review, the Board of Directors reviews and adopts best corporate governance policies and practices for the Company.

3

Code of Ethics and Business Conduct

The Company has adopted a Code of Ethics and Business Conduct that is designed to promote the highest standards of ethical conduct by the Company’s directors, executive officers and employees. The Code of Ethics and Business Conduct requires that the Company’s directors, executive officers and employees avoid conflicts of interest, comply with all laws and other legal requirements, conduct business in an honest and ethical manner and otherwise act with integrity, and in the Company’s best interest. Under the terms of the Code of Ethics and Business Conduct, directors, executive officers and employees are required to report any conduct that they believe in good faith to be an actual or apparent violation of the Code of Ethics and Business Conduct. A copy of the Code of Ethics and Business Conduct can be found in the “Investor Relations—Corporate Information—Governance Documents” section of the Company’s website, www.iroquoisfed.com.

As a mechanism to encourage compliance with the Code of Ethics and Business Conduct, the Company has established procedures for receiving, retaining and addressing complaints regarding accounting, internal accounting controls and auditing matters. These procedures ensure that individuals may submit concerns regarding questionable accounting or auditing matters in a confidential and anonymous manner. The Code of Ethics and Business Conduct also prohibits the Company from retaliating against any director, executive officer or employee who reports actual or apparent violations of the Code of Ethics and Business Conduct.

Director Independence

IF Bancorp has eight directors. The Board has determined that, except for Messrs. Alan D. Martin and Walter H. Hasselbring, each member of the Board is an “independent director” within the meaning of the Rules of the NASDAQ Stock Market, Inc. (the “Nasdaq rules”). Mr. Hasselbring is not considered independent because he is our President and Chief Executive Officer, and Alan Martin is not considered independent because he served as President and Chief Executive Officer within the past three years. In determining the independence of the directors listed above, the Board of Directors reviewed certain accounts that directors and their affiliates had with IF Bancorp, some of which are not required to be reported in this proxy statement under the heading “Transactions With Related Persons.”

Meetings of the Board of Directors

The Company conducts business through meetings of its Board of Directors and through activities of its committees. During fiscal 2018, the Board of Directors held 15 meetings. No director attended fewer than 75% of the total meetings of the Company’s Board of Directors and the board committees on which such director served.

Board Leadership Structure

At IF Bancorp, the positions of Chairman of the Board and Chief Executive Officer are held by different individuals. The Chairman of the Board provides guidance to the Chief Executive Officer, is active in setting the agenda for Board meetings and presides over meetings of the full Board and the Executive Committee. The Chief Executive Officer is responsible for setting the strategic direction for the Company and the day to day leadership and performance of the Company. As required by the Nasdaq rules, the Audit, Nominating and Compensation Committees are comprised solely of directors who are independent as defined by Nasdaq rules.

Board’s Role in Risk Oversight

The Board’s role in the Company’s risk oversight process includes receiving regular reports from members of senior management on areas of material risk to the Company, including operational, financial, legal and regulatory, strategic and reputational risks. The full Board (or the appropriate committee in the case of risks that are reviewed and discussed at committee meetings) receives these

4

reports from the appropriate “risk owner” within the organization to enable the Board or appropriate committee to understand our risk identification, risk management and risk mitigation strategies. After a committee has received and discussed a report, the chairperson of such committee reports on the discussion to the full Board at the next Board meeting. This enables the Board and its committees to coordinate the risk oversight role, particularly with respect to risk interrelationships.

Committees of the Board of Directors

The following table identifies our standing committees and their members as of September 25, 2018. All members of each committee are independent as defined by Nasdaq rules. Each committee operates under a written charter available in the “Investor Relations—Corporate Information—Governance Documents” section of the Company’s website, www.iroquoisfed.com.

Audit Committee. The Audit Committee assists the Board of Directors in its oversight of the Company’s accounting and reporting practices, the quality and integrity of the Company’s financial reports and the Company’s compliance with applicable laws and regulations. The Audit Committee is also responsible for engaging the Company’s independent registered public accounting firm and monitoring its conduct and independence. The Board of Directors has designated Dennis C. Wittenborn as an audit committee financial expert under the rules of the Securities and Exchange Commission. The report of the Audit Committee required by the rules of the Securities and Exchange Commission is included in this proxy statement under the heading “Audit Committee Report.”

Compensation Committee. The Compensation Committee approves the compensation objectives for the Company and the Association and establishes the compensation for the Chief Executive Officer and other executives. Our Chief Executive Officer and Chief Financial Officer attend committee meetings at the invitation of the committee and make recommendations to the Compensation Committee from time to time regarding the appropriate mix and level of compensation for their subordinates. Those recommendations consider the objectives of our compensation philosophy and the range of compensation programs authorized by the Compensation Committee. Our Chief Executive Officer and Chief Financial Officer do not participate in committee discussions or the review of committee documents relating to the determination of their own compensation. The Compensation Committee reviews all compensation components for the Company’s Chief Executive Officer and other highly compensated executive officers’ compensation including base salary, annual incentive, long-term incentives and perquisites. In addition to reviewing competitive market values, the committee also examines the total compensation mix, pay-for-performance relationship, and how all elements, in the aggregate, comprise the executives’ total compensation package. Decisions by the Compensation Committee with respect to the compensation of executive officers are approved by the full Board of Directors.

5

Nominating Committee. The Company’s Nominating Committee assists the Board of Directors in identifying qualified individuals to serve as Board members, and in determining the composition of the Board of Directors and its committees. The Nominating Committee also considers and recommends the nominees for director to stand for election at the Company’s annual meeting of stockholders. The procedures of the Nominating Committee required to be disclosed by the rules of the Securities and Exchange Commission are included in this proxy statement under the heading “Nominating Committee Procedures.”

Corporate Governance Committee. The Corporate Governance Committee assists the Board in developing and implementing the Company’s corporate governance guidelines, developing a director orientation program for new directors, and any additional matters related to corporate governance as may be assigned to the Committee by the Board.

Director Attendance at the Annual Meeting

The Board of Directors encourages each director to attend annual meetings of stockholders. Each current member of the Board of Directors attended the annual meeting last year.

Proposal 2 — Ratification of Independent Registered Public Accounting Firm

The Audit Committee of the Board of Directors has appointed BKD, LLP to be its independent registered public accounting firm for the 2019 fiscal year, subject to ratification by stockholders. A representative of BKD, LLP is expected to be present at the annual meeting to respond to appropriate questions from stockholders and will have the opportunity to make a statement should he or she desire to do so.

If the ratification of the appointment of BKD, LLP is not approved by a majority of the votes cast by stockholders at the annual meeting, other independent registered public accounting firms may be considered by the Audit Committee of the Board of Directors.

Unless otherwise instructed, validly executed proxies will be voted “FOR” the ratification of the appointment of BKD, LLP.

THE BOARD OF DIRECTORS RECOMMENDS THAT STOCKHOLDERS VOTE “FOR” THE RATIFICATION OF THE APPOINTMENT OF BKD, LLP AS THE COMPANY’S INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM.

Audit Fees

The following table sets forth the fees we paid to BKD, LLP for the fiscal years ended June 30, 2018 and 2017.

Pre-Approval of Services by the Independent Registered Public Accounting Firm

The Audit Committee is responsible for appointing, setting compensation and overseeing the work of the independent registered public accounting firm. In accordance with its charter, the Audit Committee approves, in advance, all audit and permissible non-audit services to be performed by the independent registered public accounting firm. Such approval process ensures that the external auditor does not provide any non-audit services to the Company that are prohibited by law or regulation.

In addition, the Audit Committee has established a policy regarding pre-approval of all audit and permissible non-audit services provided by the independent registered public accounting firm. Requests for services by the independent registered public accounting firm for compliance with the auditor services policy must be specific as to the particular services to be provided. The request may be made with respect to either specific services or a type of service for predictable or recurring services. During the year ended June 30, 2018, all services were approved, in advance, by the Audit Committee in compliance with these procedures.

Audit Committee Report

The Company’s management is responsible for the Company’s internal controls and financial reporting process. The Company’s independent registered public accounting firm is responsible for performing an independent audit of the Company’s consolidated financial statements and issuing an opinion on the conformity of those financial statements with generally accepted accounting principles. The Audit Committee oversees the Company’s internal controls and financial reporting process on behalf of the Board of Directors.

In this context, the Audit Committee has met and held discussions with management and the independent registered public accounting firm. Management represented to the Audit Committee that the Company’s consolidated financial statements were prepared in accordance with generally accepted accounting principles and the Audit Committee has reviewed and discussed the consolidated financial statements with management and the independent registered public accounting firm. The Audit Committee discussed with the independent registered public accounting firm the matters related to the results of the audit in accordance with PCAOB Standard 1301, Communications with Audit Committees, including the quality, not just the acceptability, of the accounting principles, the reasonableness of significant judgments and the clarity of the disclosures in the financial statements.

In addition, the Audit Committee has received the written disclosures and the letter from the independent registered public accounting firm required by Rule 3520 of the PCAOB Auditing Standards and has discussed with the independent registered public accounting firm the firm’s independence from the Company and its management. In concluding that the registered public accounting firm is independent, the Audit Committee considered, among other factors, whether the non-audit services provided by the firm were compatible with its independence.

The Audit Committee discussed with the Company’s independent registered public accounting firm the overall scope and plans for their audit. The Audit Committee meets with the independent registered public accounting firm, with and without management present, to discuss the results of their audit, their evaluation of the Company’s internal controls, and the overall quality of the Company’s financial reporting.

In performing all of these functions, the Audit Committee acts only in an oversight capacity. In its oversight role, the Audit Committee relies on the work and assurances of the Company’s management, which has the primary responsibility for financial statements and reports, and of the independent registered public accounting firm who, in their report, express an opinion on the conformity of the Company’s financial statements to generally accepted accounting principles. The Audit Committee’s oversight does not provide it with an independent basis to determine that management has maintained appropriate accounting and financial reporting principles or policies, or appropriate internal controls and procedures designed to assure compliance with accounting standards and applicable laws and regulations. Furthermore, the Audit Committee’s considerations and discussions with management and the independent registered public accounting firm do not ensure that the Company’s financial statements are presented in accordance with generally accepted accounting principles, that the audit of the Company’s financial statements has been carried out in accordance with standards of the Public Company Accounting Oversight Board (United States) or that the Company’s independent registered public accounting firm is in fact “independent.”

In reliance on the reviews and discussions referred to above, the Audit Committee recommended to the Board of Directors, and the board has approved, that the audited consolidated financial statements be included in the Company’s Annual Report on Form 10-K for the year ended June 30, 2018, for filing with the Securities and Exchange Commission. The Audit Committee also has approved, subject to stockholder ratification, the selection of the Company’s independent registered public accounting firm, for the fiscal year ending June 30, 2019.

Proposal 3 — Advisory Vote On Executive Compensation

The compensation of our Named Executive Officers listed in the Summary Compensation Table is described in the “Executive Officers—Executive Compensation” section. Shareholders are urged to read these sections of this proxy statement.

In accordance with Section 14A of the Securities Exchange Act of 1934 (the “Exchange Act”), stockholders will be asked at the annual meeting to provide their support with respect to the compensation of our Named Executive Officers by voting on the following advisory, non-binding resolution:

Executive Compensation

Overview

Our Board of Directors, through our Compensation Committee, is responsible for establishing and administering our executive compensation program. The Compensation Committee, consisting of Gary Martin (Chair), Joseph A. Cowan, Wayne A. Lehmann, Dennis C. Wittenborn and Rodney E. Yergler, annually reviews the executive compensation program and recommends to the Board, for its approval, appropriate modifications to the compensation packages for each of our executive officers, including specific amounts and types of compensation provided. The Compensation Committee reviews recommendations from the Chief Executive Officer regarding compensation of the named executive officers and recommends final compensation packages to the full Board for final approval. The Compensation Committee reviews the charter at least annually to ensure that the scope of the charter is consistent with the Compensation Committee’s expected role. Under the charter, the Compensation Committee is charged with general responsibility for the oversight and administration of our compensation program.

13

For fiscal 2018, our named executive officers were Walter H. Hasselbring, III, our President and Chief Executive Officer, Pamela J. Verkler, our Senior Executive Vice President, Chief Financial Officer and Treasurer and Thomas J. Chamberlain, our Executive Vice President.

Overall Compensation Philosophy and Guiding Principles

The Compensation Committee believes that the success of our Company depends on the ability to attract and retain talented executives motivated to drive the Company’s goals and provide long-term value to our stockholders.

Our compensation program is designed to link compensation with performance, taking into account competitive compensation levels in similar banks and in the markets where Iroquois Federal competes for talent. Principles guiding the compensation philosophy include the following:

The Compensation Committee, composed entirely of independent directors, sets and administers the policies that govern our executive compensation programs. The Compensation Committee reviews compensation levels of the named executive officers. The Compensation Committee evaluates the performance of our named executive officers, and considers management succession and related matters. All decisions relating to the compensation of the named executive officers are recommended by the Compensation Committee for approval of the full Board.

The policies and underlying philosophy governing our executive compensation program, as endorsed by the Compensation Committee and the Board of Directors, are designed to accomplish the following:

14

The Compensation Committee seeks to target executive compensation at levels that the Compensation Committee believes to be consistent with others in the banking industry within our marketplace. The Compensation Committee believes that a portion of each executive’s total compensation should be at risk, based on the Company’s performance, in order to motivate and reward executives to achieve the Company’s strategic goals. The named executive officers’ compensation is weighted toward programs contingent upon our level of annual and long-term performance. In general, for our named executive officers, we target base salaries that, on average, are at the 50th percentile of other banks and financial service companies of the Company’s asset size, complexity and with similar products and markets. See “Compensation Program Design” below. Goals for specific components include:

Compensation Consultant/Role of Management

The Compensation Committee has authority under its charter to engage the services of independent third party experts to assist it in reviewing and determining executive officer compensation. Pursuant to this authority, the Compensation Committee engaged Compensation Advisors in fiscal 2018 to conduct comparative studies of our compensation for executive officers and members of our Board of Directors, and related to benchmarking chief executive officer compensation in connection with the Governance and Nominating Committee process.

The Chief Executive Officer annually presents to the Compensation Committee, for their review and approval, his self-evaluation and an assessment of other executive officers, including each individual’s accomplishments, and individual and corporate performance relative to the approved incentive plan. The Committee has discretion to adjust the Chief Executive Officer’s recommendations, but generally has approved his recommendations for executive officers.

Compensation Committee Activities in Fiscal 2018

The Compensation Committee met 9 times during the fiscal year ended June 30, 2018. The Company took several actions during fiscal 2018 to further adjust our executive officer compensation program to correspond to our status as a publicly traded stock institution and to create alignment with the interests of our stockholders, including engaging Compensation Advisors as compensation consultant to assess the competitiveness of our executive total compensation program and to provide competitive guidelines for programs going forward. The compensation consultant also provided services related to chief executive officer salary benchmarking. The Compensation Committee reviewed executive salaries, performance and competitive market pay practices (see “Executive Compensation Program Design – Use of Compensation Survey”), and based on such assessment, recommended a 10.0% increase in base salary for Mr. Hasselbring, a 6.9% increase for Ms. Verkler and a 7.6% increase for Mr. Chamberlain.

Objectives of Our Compensation Programs

Our executive officer compensation program is designed to:

Executive Compensation Program Design

Cash Compensation

Current cash compensation consists of base salary and bonuses, which covers executive officers and other Iroquois Federal employees. Our base salary levels for executive officers are intended to be competitive with our peer group, to motivate individuals to discharge the responsibilities of their position, and to reflect the officer’s role, responsibilities, experience, performance and contribution to the Company’s success. Our Compensation Committee considers base salaries of executive officers annually with input from our President and Chief Executive Officer, and makes such adjustments as are warranted. In making these adjustments, our Compensation Committee takes into account individual and Company performance; the total current and potential compensation of a given officer based on a review; the levels of compensation paid by institutions that compete with us for executive talent; and the relative level of compensation in comparison to other executive officers and to our employees.

Non-Equity Incentive Compensation

The Iroquois Federal Annual Incentive Plan (the “Incentive Plan”) provides the opportunity for eligible executives to earn non-equity incentive compensation upon the attainment of specified objectives. The Board sets a minimum acceptable return to shareholders each year which is required to be met before any incentive payments can be made. Incentive awards under this Incentive Plan are based on a 3-year rolling performance cycle to encourage ongoing exceptional performance.

Equity Compensation

The IF Bancorp, Inc. 2012 Equity Incentive Plan (the “Equity Incentive Plan”) was established to provide officers, employees, and directors of IF Bancorp and Iroquois Federal with additional incentives to promote the growth and performance of IF Bancorp. Awards granted in the year ended June 30, 2014, include restricted stock which vests over 10 years and stock options which vest over 7 years. Awards granted in the year ended June 30, 2016 include restricted stock which vests over 8 years.

16

Benefits and Perquisites

Executive officers also receive broad based benefits that are available to all qualifying employees of the Company. These include a defined contribution 401(k) plan and a discretionary profit sharing plan, an employee stock ownership plan, medical coverage, and group life and disability coverage. In addition, the Company provides a cell phone and incurs the expense of country club dues for executive officers.

Use of Compensation Survey

The Compensation Committee relies on peer group surveys prepared by its consultant, Compensation Advisors, to assess the competitiveness of the Company’s pay practices in the marketplace. The peer group data is used in combination with other supplemental published survey sources reflecting industry data for banks of similar size (national financial institutions with assets between $457.7 million and $1.1 billion) and for banks in our region, as well as with information relating to individual and Company performance, to help the Compensation Committee make compensation decisions. Compensation Advisors selected a peer group and benchmarked the Company’s cash compensation (base salary plus annual cash incentive compensation) against this group. The peer group consisted of 18 publicly traded financial institutions of similar asset size and regional location. The median assets for the peer group are $739.7 million, as compared to $611.5 million for IF Bancorp, Inc. The peer group consisted of:

Tax and Accounting Considerations

In consultation with our advisors, we evaluate the tax and accounting treatment of each of our compensation programs at the time of adoption and on an annual basis to ensure that we understand the financial impact of the program. Our analysis includes a detailed review of recently adopted and pending changes in tax and accounting requirements. As part of our review, we consider modifications and/or alternatives to existing programs to take advantage of favorable changes in the tax or accounting

17

environment or to avoid adverse consequences. We attempt to maximize the tax benefits related to compensation expense, however, tax considerations are not a compelling factor in determining compensation. The Compensation Committee intends for all compensation to be compliant under Rule 162(m) of the Internal Revenue Code to permit us to realize tax benefits of all compensation paid to the named executive officers; however, none of the officers currently receive compensation close to the $1,000,000 threshold.

Summary Compensation Table

The following information is provided for our Chief Executive Officer and two other most highly compensated executive officers who received compensation totaling $100,000 or more for the years ended June 30, 2018 and June 30, 2017, referred to herein as the “named executive officers.”

Employment Agreement

Iroquois Federal Savings and Loan Association and IF Bancorp, Inc. each have entered into an employment agreement with Walter H. Hasselbring, III, our President and Chief Executive Officer, effective November 25, 2015, with amendments effective July 1, 2016 and July 1, 2017. The Iroquois Federal agreement and the IF Bancorp agreement each provide for a three-year term, subject to annual renewal by the disinterested members of the Board of Directors. Prior to each such renewal, the disinterested members of the Board of Directors conduct a comprehensive performance evaluation for purposes of determining whether to extend the agreements. Both agreements have been renewed effective July 7, 2018 for a term ending on July 7, 2021. Although the agreements are substantially similar and each requires payments to the executive under certain circumstances, there will be no duplication of benefits. Any payment made under the Iroquois Federal agreement will be subtracted from the same payment required under the IF Bancorp, Inc. agreement.

Mr. Hasselbring’s base salary under his employment agreement with Iroquois Federal is $308,000. In addition to base salary, the agreement provides for, among other things, Mr. Hasselbring’s right to participate in discretionary bonuses or other incentive compensation programs and employee benefit plans and to receive perquisites applicable to executive management. If we terminate Mr. Hasselbring without cause or if he terminates voluntarily under specified circumstances that constitute good reason (as defined in the agreements), Mr. Hasselbring will be entitled to three times the sum of (i) base salary and (ii) the highest annual bonus (whether paid or accrued) during the prior three years and the value of all employee benefits that would have been provided for the 36-month period following the his termination, had his employment not terminated. Such amounts will be paid in a lump sum payment. In addition, Mr. Hasselbring will be entitled to participate in any life insurance, non-taxable medical, health, or dental arrangement, subject to the same premium contribution as prior to his termination, until the earlier of his death, his employment by another employer other than one in which he is the majority owner, or for the 36-month period immediately following his termination. In the event that IF Bancorp or Iroquois Federal do not provide welfare benefits at any time after the executive’s termination or if providing such benefits would subject Iroquois Federal to excise taxes or penalties, then executive will receive a lump sum payment equal to the premiums for such benefits. If there is a change in control followed within 24 months by Mr. Hasselbring’s dismissal or resignation due to a demotion, loss of title, office or significant authority, reduction in compensation or benefits, or relocation by more than 35 miles, he will be entitled to the greater of the payments set forth above or three times his average annual compensation (as “annual compensation” is defined in the employment agreements) over the last five years ending before the year in which the change in control occurs, payable in a lump sum, plus, continued welfare benefits either provided under the Iroquois Federal plans for a period of up to the earlier of his death, employment by another employer other than one of which he is the majority owner, or the expiration of 36 months, or by payment of a cash lump sum payment equal to the cost of providing such benefits for up to 36 months. In addition, any memberships or automobile use shall be continued during the remaining unexpired term of the agreement (or if less, the maximum period permitted under Internal Revenue Code Section 409A without being considered deferred compensation). The payments required under the Iroquois Federal employment agreement in connection with a change in control will be reduced to the extent necessary to avoid an excess parachute payment. The IF Bancorp, Inc. agreement will not require a reduction in severance benefits on a termination of employment in connection with a change in control in the event of an excess parachute payment

In the event of Mr. Hasselbring’s death during the term of the agreements, Mr. Hasselbring’s dependents will continue to receive non-taxable medical insurance benefits for a period of six months following his death. In the event of his disability (as construed in accordance with Internal Revenue Code Section 409A), the agreements provide that Mr. Hasselbring will be entitled to 100% of his base salary for 180 days following his disability termination and 60% of his base salary from the 181^st day following

19

termination until the earlier of the date of his death or the date he attains age 65. Such payments will be reduced by any short or long-term disability benefits payable under any disability program to which he is entitled. To the greatest extent possible, Mr. Hasselbring and his dependents will be covered under life and non-taxable medical and dental plans of Iroquois Federal, on the same terms as Mr. Hasselbring participated prior to his disability termination.

Change in Control Agreements

Iroquois Federal has entered into change in control agreements with Ms. Verkler and Mr. Chamberlain. Each of the agreements provides for a 24-month term, subject to annual renewal by the disinterested members of the Board of Directors on July 7 of each year. Prior to each such renewal, the disinterested members of the Board of Directors conduct a comprehensive performance evaluation for purposes of determining whether to extend the agreements. Each agreement was renewed in fiscal 2018. In the event of a change in control (as defined in the agreement), each agreement will automatically renew for a term of 12 months following the effective date of the change in control. The agreements will terminate if the executive or Iroquois Federal terminates executive’s employment prior to a change in control. If, within 12 months after a change in control, we terminate the executive without cause or if the executive terminates voluntarily under specified circumstances that constitute good reason, including a material diminution in authority, duties or responsibilities, a material diminution in base salary, a relocation that increases the executive’s commute by more than 35 miles, or any other action or inaction by the bank or IF Bancorp, Inc. that would constitute a breach of the agreement, the executive will be entitled to a lump sum cash payment equal to two times the executive’s base salary and highest rate of bonus paid to the executive during the three years prior to termination, payable in a single lump sum within ten days following the termination of employment. In addition, the executive will be entitled to continue participation in life insurance, non-taxable medical, vision, and dental coverage, subject to the same terms and conditions as prior to the executive’s termination of employment. Such coverage will cease 24 months after the executive’s termination. In the event the provision or payment of such benefit would subject Iroquois Federal to excise taxes or penalties, Iroquois Federal will pay to the executive a cash lump sum payment equal to the cost of providing such benefits. The payments required under the change in control agreements will be reduced to the extent necessary to avoid an excess parachute payment. Payments under the agreements will be paid from the general funds of Iroquois Federal; IF Bancorp, Inc., however, will guarantee the payments due under the agreements. We will agree to pay all reasonable costs and legal fees of the executive in relation to the enforcement of the change in control agreements, provided the executive succeeds on the merits in a legal judgment, arbitration proceeding or settlement.

Annual Incentive Plan

In the fiscal year ended June 30, 2012, Iroquois Federal entered into the Iroquois Federal Annual Incentive Plan (the “Incentive Plan”). The Incentive Plan provides the opportunity to earn an incentive award to employees who have been designated by the committee administering the Incentive Plan as eligible to participate and who have been approved by the Iroquois Federal Board of Directors, based upon attainment of specified objectives, determined periodically by the Iroquois Federal Board of Directors. The plan incorporates two key components. First, a minimum acceptable return to shareholders is established each year, which is required to be met before incentive payments can be made. Second, the plan provides for a 3-year rolling performance cycle, with incentive awards made at the end of each cycle. After achievement of the minimum acceptable return to shareholders, Iroquois Federal contributes a percentage of Iroquois Federal’s earnings above the minimum acceptable return to an eligible participant incentive pool, which is used to fund awards to participants under the Incentive Plan. During the first two years of the initial 3-year performance cycle, the Iroquois Federal Board of Directors made partial payments of the ultimate initial 3-year incentive award. The 2014 fiscal year marked the end

20

of the initial 3-year performance cycle. Starting in 2015 fiscal year, incentive awards under the Incentive Plan are made based on the full 3-year rolling performance cycle. Payment of any award under the Incentive Plan is conditioned upon Iroquois Federal’s financial capacity to fund the payment. If Iroquois Federal is not financially capable of funding the payment of an award at the time it is due, the payment may be reduced or eliminated. The award for each participant is based on the participants’ compensation and the objectives determined by the Iroquois Federal Board of Directors.

Generally, a participant must be employed by Iroquois Federal or IF Bancorp on the date that the amounts credited to the participant’s account are distributed to the participant. In the year in which a participant retires, dies, becomes disabled, or has an involuntary separation from service without cause or resigns for good reason (as defined in the Incentive Plan), special vesting provisions apply and generally would permit a payment to the participant for the performance cycle that would end in that year, provided that all performance measures are attained by the participant for such performance cycle, and in the case of the participant’s retirement, the participant worked at least six months during the Incentive Plan year in which he or she retires. In the event of a change in control (as defined in the Incentive Plan) all unvested awards will become fully vested and will be paid in a lump sum within 30 days after the effective date of the change in control. In the event of separation from service for cause, all vested and unvested awards will expire as of the date of the separation from service.

In the event the Iroquois Federal Board of Directors determines that a participant has engaged in fraud or willful misconduct that caused or contributed to the need for a material restatement of IF Bancorp’s financial results, the Board of Directors will review all awards previously awarded to, or earned by, the participant on the basis of performance during the fiscal periods materially affected by the restatement and may, to the extent permitted by law, recoup from the participant or from the participant’s incentive account any portion of awards as it deems appropriate after review of all relevant facts and circumstances.

Equity Incentive Plan

Our shareholders have approved the IF Bancorp, Inc. 2012 Equity Incentive Plan (the “Equity Incentive Plan”), to provide officers, employees and directors of IF Bancorp and Iroquois Federal with additional incentives to promote the growth and performance of IF Bancorp. Subject to permitted adjustments for certain corporate transactions, the Equity Incentive Plan authorizes the issuance or delivery to participants of up to 673,575 shares of IF Bancorp common stock pursuant to grants of incentive and non-qualified stock options, restricted stock awards and restricted stock unit awards, provided that the maximum number of shares of Company common stock that may be delivered pursuant to the exercise of stock options (all of which may be granted as incentive stock options) is 481,125 and the maximum number of shares of Company stock that may be issued as restricted stock awards or restricted stock units is 192,450. Employees and directors of IF Bancorp or its subsidiaries are eligible to receive awards under the Equity Incentive Plan, except that non-employees may not be granted incentive stock options.

The Compensation Committee may determine the type and terms and conditions of awards under the Equity Incentive Plan. Awards may be granted in a combination of incentive and non-statutory stock options, and/or restricted stock awards and restricted stock units, as follows. The Equity Incentive Plan is designed so that stock options will be considered “qualified performance-based compensation.” The Committee may designate whether any restricted stock awards or restricted stock units being granted to any participant are intended to be “qualified performance-based compensation.” Any such awards designated as intended to be “qualified performance-based compensation” will be conditioned on the achievement of one or more performance measures, to the extent required by Section 162(m) of the Internal Revenue Code. If the right to become vested in an award under the Equity Incentive Plan is

21

conditioned on the completion of a specified period of service with IF Bancorp or its subsidiaries, without the achievement of performance measures or objectives, then the required period of service for full vesting shall be determined by the Committee and evidenced in an award agreement, subject to acceleration of vesting, to the extent permitted by the Committee, upon the occurrence of certain events, including in the event of death or disability. Unless otherwise stated in an award agreement, upon the occurrence of an involuntary termination of employment or termination of service as a director following a change in control of IF Bancorp, all outstanding options then held by a participant will become fully exercisable and all restricted stock awards and/or restricted stock units shall be fully earned and vested. In the event of a change in control, any performance measure attached to an award under the Equity Incentive Plan shall be deemed satisfied in full as of the date of the change in control.

Certain limits apply to awards under the Equity Incentive Plan. The maximum number of shares that may be subject to restricted stock awards (or restricted stock unit awards) and the maximum number of shares that may be subject to stock option awards available to non-employee directors under the Equity Incentive Plan shall not exceed 5% of the shares available for grant as restricted stock (or restricted stock units) and 5% of the shares available for grant as stock options, respectively, under the plan. The maximum number of shares that may be granted to non-employee directors, in the aggregate, shall not exceed 30% of the shares available for grant as restricted stock (or restricted stock units) and as stock options, respectively, under the plan. The maximum number of shares of stock that may be subject to stock options intended to be performance-based compensation under Code Section 162(m) granted to any one employee during any calendar year shall not exceed 120,281 shares.

The Equity Incentive Plan provides that neither the Committee nor the Board is authorized to make any adjustment or amendment that reduces or would have the effect of reducing the exercise price of a stock option previously granted.

Stock Based Compensation

Retirement Benefits

Retirement benefits have become an important element of a competitive compensation program for attracting senior executives, especially in the financial services industry. Our executive compensation program currently includes (i) a 401(k) plan which enables our employees to supplement their retirement savings with elective deferral contributions with matching contributions by us at specific levels, and an employer profit sharing contribution which allows eligible participants to receive at least 5% of their Plan year salary, and (ii) an employee stock ownership plan that allows participants to accumulate retirement benefits in employer stock at no cost to the participant.

Director Compensation

Each individual who serves as a director of Iroquois Federal receives an annual retainer of $40,533, except the Chairman of the Board receives an annual retainer of $84,222 and the Chairman of the Audit Committee receives a retainer of $49,130.

Each person who serves as a director of IF Bancorp, Inc. also serves as a director of Iroquois Federal and earns director and committee fees only in his or her capacity as a Board or committee member of Iroquois Federal.

The following table sets forth for the year ended June 30, 2018 certain information as to the total remuneration we paid to our directors other than Mr. Walter H. Hasselbring, III, who is also our President and Chief Executive Officer. Information with respect to director fees paid to Mr. Hasselbring is included in “—Executive Officer Compensation—Summary Compensation Table.”

Director’s Non Qualified Retirement Plan

Iroquois Federal maintains a Directors’ Non Qualified Retirement Plan, which was amended and restated on October 10, 2006. The purpose of the plan is to provide a retirement benefit to directors and directors emeriti of Iroquois Federal. Upon a director’s termination of service on or after normal retirement age (age 72), the director will be entitled to the average annual cash compensation received for the three years prior to retirement, payable in monthly installments over a ten-year period. In the event of

23

a director’s retirement on or after his or her early retirement date (the later of age 65 or the date the director has continuously been elected to the Board of Directors for ten years), the director will be entitled to his or her accrual balance (as defined in the plan), payable over a ten-year period, in monthly installments. In the event of the director’s termination of service due to disability, the director will receive his or her accrual balance, payable over a ten-year period, in monthly installments. In the event a director leaves the Board of Directors for any reason within 24 months after a change in control, the director will be paid his or her accrual balance earned as of the last day of the plan year preceding the date of termination in one lump sum within three days after the director’s removal from the Board of Directors. In the event a change in control occurs while the director is receiving normal or early retirement benefits, or disability benefits, the director will receive the remaining benefits in a single lump sum payment within three days after the change in control. In the event of the director’s death during active service, Iroquois Federal will pay a death benefit equal to the accrual balance as of the last day of the plan year immediately preceding the date of the director’s death; payment will be made within 30 days after the director’s death. In the event of a director’s death after the director is entitled to benefits but before payments commence, or after benefits commence but before the director has received all benefit payments, benefits will be paid to the director’s beneficiary in the same amounts as would have been made to the director, had the director survived.

Executive officers, directors and greater than 10% stockholders are required by regulation to furnish the Company with copies of all Section 16(a) reports they file.

Based solely on the Company’s review of copies of the reports it has received and written representations provided to it from the individuals required to file the reports, the Company believes that each of its executive officers and directors has complied with applicable reporting requirements for transactions in IF Bancorp common stock during the year ended June 30, 2018.

Transactions with Related Persons

Federal regulations require that all loans or extensions of credit to executive officers and directors of insured institutions must be made on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable transactions with other persons, and must not involve more than the normal risk of repayment or present other unfavorable features. Notwithstanding this rule, federal regulations permit the Association to make loans to executive officers and directors at reduced interest rates if the loan is made under a benefit program generally available to all Association employees and does not give preference to any executive officer or director over any other employee. Iroquois Federal maintains loan programs whereby employees, including executive officers and directors, may obtain loans at the discounted rate of 1% above the Bank’s cost of funds as of the most recent month end, rounded up to the nearest one quarter point. The discounted rate on any such loans will not exceed a term of 60 months. Iroquois Federal will also waive the loan origination fee on new mortgage loans. The following information is furnished for loans to executive officers and directors under these loan programs during fiscal 2018 and 2017.

From time to time, Iroquois Federal also makes loans and extensions of credit, directly and indirectly, to its executive officers and directors that are not part of the loan programs discussed above. These loans are made in the ordinary course of business, are made on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable loans with persons not related to Iroquois Federal, and do not involve more than the normal risk of collectibility or present other unfavorable features.

In accordance with banking regulations, the Board of Directors reviews all loans made to a director or executive officer in an amount that, when aggregated with the amount of all other loans to such person and his or her related interests, exceed the greater of $25,000 or 5% of IF Bancorp’s capital and surplus (up to a maximum of $500,000) and such loan must be approved in advance by a majority of the disinterested members of the Board of Directors. Additionally, pursuant to the Company’s Code of Ethics and Business Conduct, all executive officers and directors of IF Bancorp must disclose any existing or emerging conflicts of interest to the President and Chief Executive Officer of IF Bancorp. Such potential conflicts of interest include, but are not limited to, the following: (i) IF Bancorp conducting business with or competing against an organization in which a family member of an executive officer or director has an ownership or employment interest and (ii) the ownership of more than 1% of the outstanding securities or 5% of total assets of any business entity that does business with or is in competition with IF Bancorp.

Nominating Committee Procedures

General

It is the policy of the Nominating Committee of the Board of Directors of the Company to consider director candidates recommended by stockholders who appear to be qualified to serve on the Company’s Board of Directors. The Nominating Committee may choose not to consider an unsolicited recommendation if no vacancy exists on the Board of Directors and the Nominating Committee does not perceive a need to increase the size of the Board of Directors. To avoid the unnecessary use of the Nominating Committee’s resources, the Nominating Committee will consider only those director candidates recommended in accordance with the procedures set forth below.

Procedures to be Followed by Stockholders

To submit a recommendation of a director candidate to the Nominating Committee, a stockholder should submit the following information in writing, addressed to the Chairman of the Nominating Committee, care of the Corporate Secretary, at the main office of the Company located at 201 East Cherry Street, Watseka, Illinois 60970:

In order for a director candidate to be considered for nomination at the Company’s annual meeting of stockholders, the recommendation must be received by the Nominating Committee at least 180 calendar days before the date the Company’s proxy statement was released to stockholders in connection with the previous year’s annual meeting, advanced by one year.

30

Process for Identifying and Evaluating Nominees

The process that the Nominating Committee follows to identify and evaluate individuals to be nominated for election to the Board of Directors is as follows:

Identification. For purposes of identifying nominees for the Board of Directors, the Nominating Committee relies on personal contacts of the committee members and other members of the Board of Directors, as well as its knowledge of members of the communities served by Iroquois Federal. The Nominating Committee will also consider director candidates recommended by stockholders in accordance with the policy and procedures set forth above. The Nominating Committee has not previously used an independent search firm to identify nominees.

Evaluation. In evaluating potential nominees, the Nominating Committee determines whether the candidate is eligible and qualified for service on the Board of Directors by evaluating the candidate under certain criteria, which are described below. If such individual fulfills these criteria, the Nominating Committee will conduct a check of the individual’s background and interview the candidate to further assess the qualities of the prospective nominee and the contributions he or she would make to the Board of Directors.

Qualifications

The Nominating Committee has adopted a set of criteria that it considers when it selects individuals to be nominated for election to the Board of Directors. A candidate must meet the eligibility requirements set forth in the Company’s bylaws, which include an age restriction, a residency requirement and a requirement that the candidate not have been subject to certain criminal or regulatory actions. A candidate also must meet any qualification requirements set forth in any Board or committee governing documents.

If the candidate is deemed eligible for election to the Board of Directors, the Nominating Committee will then evaluate the following criteria in selecting nominees:

The Committee will also consider any other factors the Nominating Committee deems relevant, including age, diversity, size of the Board of Directors and regulatory disclosure obligations. We do not maintain a specific diversity policy, but diversity is considered in our review of candidates. Diversity includes not only gender and ethnicity, but the various perspectives that come from having differing viewpoints, geographic and cultural backgrounds, and life experiences.

With respect to nominating an existing director for re-election to the Board of Directors, the Nominating Committee will consider and review an existing director’s board and committee attendance and performance; length of board service; experience, skills and contributions that the existing director brings to the Board; and independence.

31

Submission of Business Proposals and Stockholder Nominations

The Company must receive proposals that stockholders seek to include in the proxy statement for the Company’s next annual meeting no later than June 17, 2019. If next year’s annual meeting is held on a date more than 30 calendar days from November 19, 2019, a stockholder proposal must be received by a reasonable time before the Company begins to print and mail its proxy solicitation for such annual meeting. Any stockholder proposals will be subject to the requirements of the proxy rules adopted by the Securities and Exchange Commission.

The Company’s bylaws provide that, in order for a stockholder to make nominations for the election of directors or proposals for business to be brought before the annual meeting, a stockholder must deliver notice of such nominations and/or proposals to the Secretary not less than 80 days before the date of the annual meeting. However, if less than 90 days’ notice or prior public disclosure of the date of the annual meeting is given to stockholders, such notice must be received not later than the close of business of the tenth day following the day on which notice of the date of the annual meeting was mailed to stockholders or prior public disclosure of the meeting date was made. A copy of the bylaws may be obtained from the Company.

Stockholder Communications

The Company encourages stockholder communications to the Board of Directors and/or individual directors. All communications from stockholders should be addressed to IF Bancorp, Inc., 201 East Cherry Street, Watseka, Illinois 60970. Communications to the Board of Directors should be in the care of Beth A. Warren, Corporate Secretary. Communications to individual directors should be sent to such director at the Company’s address. Stockholders who wish to communicate with a Committee of the Board should send their communications to the care of the Chair of the particular committee, with a copy to Gary Martin, the Chair of the Corporate Governance Committee of the Board of Directors. It is in the discretion of the Corporate Governance Committee whether any communication sent to the full Board should be brought before the full Board.

Miscellaneous

The Company will pay the cost of this proxy solicitation. The Company 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 the Company. Additionally, directors, officers and other employees of the Company may solicit proxies personally or by telephone without receiving additional compensation.

The Company’s Annual Report to Stockholders has been included with this proxy statement. Any stockholder who has not received a copy of the Annual Report may obtain a copy by writing to the Corporate Secretary of the Company. The Annual Report is not to be treated as part of the proxy solicitation material or as having been incorporated by reference into this proxy statement.

If you and others who share your address own your shares in “street name,” your broker or other holder of record may be sending only one annual report and proxy statement to your address. This practice, known as “householding,” is designed to reduce our printing and postage costs. However, if a stockholder residing at such an address wishes to receive a separate annual report or proxy statement in the future, he or she should contact the broker or other holder of record. If you own your shares in “street name” and are receiving multiple copies of our annual report and proxy statement, you can request householding by contacting your broker or other holder of record.

ESOP VOTE AUTHORIZATION FORM — IF BANCORP, INC.

CONFIDENTIAL ESOP VOTING INSTRUCTIONS SOLICITED ON BEHALF OF THE TRUSTEE OF IROQUOIS FEDERAL SAVINGS AND LOAN ASSOCIATION EMPLOYEE STOCK OWNERSHIP PLAN

FOR THE ANNUAL MEETING OF STOCKHOLDERS TO BE HELD ON NOVEMBER 19, 2018

The Iroquois Federal Savings and Loan Association Employee Stock Ownership Plan (the “ESOP”) allows ESOP participants to vote the common stock of IF Bancorp, Inc. (the “Company”). In accordance with ESOP procedures, participants who have shares allocated to their accounts as of September 25, 2018 (the “voting record date”) have the right to direct the Trustee as to the voting of such shares at the Company’s Annual Meeting of Stockholders (the “Annual Meeting”) to be held at the administrative office of Iroquois Federal Savings and Loan Association located at 204 East Cherry Street, Watseka, Illinois, on Monday, November 19, 2018, at 2:00 p.m., local time. Therefore, as a participant in the ESOP, you are entitled to instruct the ESOP Trustee how to vote the shares of Company common stock allocated to your account at the Annual Meeting by completing and returning this ESOP Vote Authorization Form.

The ESOP Trustee is directed to vote the shares of Company common stock allocated to participants’ accounts in accordance with the voting instructions received from participants, so long as such vote is in accordance with the provisions of the Employee Retirement Income Security Act of 1974, as amended.

The Company is forwarding the Confidential ESOP Voting Instructions and ESOP Vote Authorization Form so that you may convey your voting instructions on the matters to be considered at the Annual Meeting and on such other business as may properly come before the Annual Meeting or any adjournment or postponement thereof. The Company is not aware of any other business to be brought before the Annual Meeting other than as set forth in the accompanying proxy statement. Your individual vote will not be revealed to the Company or the Bank. The Company has retained ComputerShare as its agent to receive the ESOP Vote Authorization Forms completed by participants in the ESOP and to tabulate the results. In order to direct the voting of the shares allocated to your account, you must complete, sign and date the ESOP Vote Authorization Form and return it in the accompanying postage-paid envelope to ComputerShare.

YOUR ESOP VOTE AUTHORIZATION FORM MUST BE RECEIVED BY COMPUTERSHARE NO LATER THAN MONDAY, NOVEMBER 12, 2018, SEVEN (7) DAYS BEFORE THE ANNUAL MEETING DATE. YOUR INDIVIDUAL VOTE WILL NOT BE REVEALED TO THE COMPANY.

Your confidential vote and the votes of other participants will be tallied by ComputerShare who will direct the Trustee to:

and in either case, so long as such vote is solely in the interests of participants and beneficiaries and in accordance with the requirements of the Employee Retirement Income Security Act of 1974, as amended. The effect of the foregoing procedure is that all shares of the Company’s common stock held in the ESOP (including unallocated shares) will be voted either FOR or AGAINST (or, in the case of director nominees, FOR or WITHHOLD) each of the proposals listed on the ESOP Vote Authorization Form.

Thus, if you provide timely voting instructions, you, in effect, will be voting the shares allocated to your ESOP account and participating in the voting of unallocated shares and shares allocated to other ESOP participants’ accounts as to which timely voting instructions are not received or an instruction to ABSTAIN is received.
