Item 8.01 Other Events.

As previously reported, on October 29, 2025, ServBanc Holdco, Inc. (“ServBanc”), an Arizona corporation and registered bank holding company under the Bank Holding Company Act of 1956, as amended, and IF Bancorp, Inc. (the “Company”), a Maryland corporation and registered savings and loan holding company under the Home Owners’ Loan Act of 1933, as amended, entered into an Agreement and Plan of Merger (the “Merger Agreement”), pursuant to which (1) the Company will merge with and into SBHI Holdings, Inc., a Maryland-chartered subsidiary of ServBanc with the Company as the surviving corporation (the “Merger”), (2) concurrently with the Merger or as soon thereafter as is reasonably practicable, the Company will be merged with and into ServBanc, with ServBanc surviving the merger (the “Second Merger”), and (3) immediately following the Second Merger, Iroquois Federal Savings and Loan Association, a wholly owned subsidiary of the Company (the “Bank”) will be merged with and into Servbank, National Association, a wholly owned subsidiary of ServBanc (“Servbank”), with Servbank the surviving entity.

In connection with the Merger, the Company initially filed with the U.S. Securities and Exchange Commission (the “SEC”) a preliminary proxy statement on December 8, 2025. The Company filed the definitive proxy statement with the SEC on December 30, 2025, and the Company first mailed the proxy statement to shareholders on or about December 30, 2025.

Following the announcement of the Merger Agreement and as of the date of this Current Report on Form 8-K, purported shareholders of the Company filed the following lawsuits in the Supreme Court of New York, County of New York, against the Company and the individual members of the Company’s board of directors: (i) Walsh v. IF Bancorp, Inc., et al., Index No. 650238/2026 (January 13, 2026); and (ii) Thompson v. IF Bancorp, Inc., et al., Index No. 650277/2026 (January 15, 2026) (together, the “Complaints”). In addition, between January 13, 2026 and January 16, 2026, the Company received four demand letters from counsel, each representing other individuals who are purported shareholders of the Company (collectively, the “Demands” and, together with the Complaints, the “Matters”). The Matters allege, among other things, that the Company and/or its directors caused a false and misleading proxy statement relating to the Transaction to be filed with the SEC and/or are liable for negligence and negligent misrepresentation and concealment under state common law.

The Company believes that the allegations in the Matters are wholly without merit, that the disclosures in the proxy statement comply fully with applicable laws, and that no additional disclosures are required or necessary under applicable laws. However, to moot the disclosure claims, avoid the risk that the Matters delay or otherwise adversely affect the special meeting of the Company’s shareholders or the closing of the Merger, and to avoid the cost and distraction of litigation, and without admitting any liability or wrongdoing, the Company is making additional disclosures as described in this Current Report on Form 8-K. The Company and its directors expressly deny that they have violated any laws, negligently misrepresented or concealed any information, or breached any fiduciary duties. Nothing in this Current Report on Form 8-K shall be deemed an admission of the legal necessity or materiality under applicable laws of any of the disclosures set forth herein or in the proxy statement. To the contrary, the Company and its directors specifically deny all allegations in the Matters and that any additional disclosure in the proxy statement was or is required.

The disclosure on page 38 of the proxy statement is hereby supplemented by adding the following section immediately after the section entitled “Opinion of the Company’s Financial Advisor” and immediately before the section entitled “Interest of Directors and Officers in the Merger that are Different from Your Interests”:

Certain Unaudited Prospective Financial Information

The Company does not, as a matter of course, publicly disclose forecasts or internal projections as to its future performance, financial condition, revenues, earnings or other results due to, among other reasons, the inherent uncertainty of the underlying assumptions and estimates.

However, in connection with the merger, certain unaudited prospective financial information for the Company is being made available as described below. We refer to this information collectively as the “prospective financial information.” A summary of certain significant elements of this information is included herein solely for the purpose of providing the Company’s shareholders access to certain information considered by the Company’s board of directors and made available to KBW for the purpose of performing financial analyses in connection with its opinion.

The prospective financial information was not prepared with a view toward public disclosure or compliance with published guidelines of the SEC, the guidelines established by the American Institute of Certified Public Accountants for preparation and presentation of prospective financial information, or GAAP. The prospective financial information included in this proxy statement was prepared by, and is the responsibility of, management of the Company. The Company’s independent auditor, Forvis Mazars, LLP, did not examine, compile or perform any procedures with respect to the prospective financial information and, accordingly, such firm does not express an opinion or any other form of assurance with respect thereto.

The prospective financial information is a forward-looking statement that is subject to risks and uncertainties that could cause actual results to differ materially from such estimate and should be read with caution. Although presented with numerical specificity, this prospective financial information is based upon a variety of assumptions made by management of the Company with respect to, among other things, industry performance, general economic, market, interest rate, and financial conditions, the timing and level of new loan originations and deposit generation, operating and other revenues and expenses, effective tax rates, capital expenditures, working capital and other matters. Some or all of the assumptions may not be realized, and as historical performance suggests, they are inherently subject to significant business, economic and competitive uncertainties and contingencies, all of which are difficult to predict and many of which are beyond the control of the Company. In addition, some of these assumptions, by their nature, are subjective in many respects.

Accordingly, the assumptions made in preparing the prospective financial information may prove to be inaccurate and actual results may differ materially from this estimate. In addition, the prospective financial information does not take into account any of the expense savings or charges expected to result from the proposed merger or any other matters contemplated by the Merger Agreement, including limitations imposed in the Merger Agreement on the Company’s ability to engage in certain activities pending completion of the merger without ServBanc’s consent.

For these reasons, the prospective financial information in this proxy statement should not be regarded as an indication that it is necessarily predictive of actual future performance and it should not be relied on as such. No one has made, or makes, any representation regarding the prospective financial information by its inclusion in this proxy statement and, except as may be required by applicable securities laws, the Company does not intend to update or otherwise revise the projection to reflect circumstances existing after the date when made or to reflect the occurrence of future events even if any or all of the assumptions underlying the projection are shown to be in error. For additional information on factors that may cause future financial results to materially vary from what is reflected in the projection prepared by management of the Company, see the section entitled “Cautionary Statement Concerning Forward-Looking Information.”

The following prospective financial information regarding the Company was provided by Company to KBW for the purpose of performing financial analyses in connection with its opinion: (i) estimated total assets and net income as of and for the twelve months ending December 31, 2025 and 2026 as presented in the table below, with an assumed annual growth rate of 7.5% for earnings per share and assets thereafter, and (ii) estimated accumulated other comprehensive income (loss) of $(14.5) million for the twelve months ending December 31, 2025, and $(9.3) million for the twelve months ending December 31, 2026, with accumulated other comprehensive income (loss) holding constant on an annual basis thereafter.

The following table presents certain unaudited prospective financial information regarding the Company as of and for the twelve months ending December 31, 2025 and 2026, which was provided by Company to KBW for the purpose of performing financial analyses in connection with its opinion:

	2025		2026
Net Income ($ in millions)	$	4.9	$	8.6
Total Consolidated Assets at December 31 ($ in millions)	$	873.8	$	894.7

Forward-Looking Statements

Undue reliance should not be placed on the forward-looking statements, which speak only as of the date hereof. Neither ServBanc nor the Company undertakes, and each specifically disclaims any obligation, to publicly release the result of any revisions that may be made to update any forward-looking statement to reflect the events or circumstances after the date on which the forward-looking statement is made, or reflect the occurrence of unanticipated events, except to the extent required by law.
