On March 9, 2026, in conjunction with their proposed merger (the “Merger”), ServBanc Holdco, Inc. (“ServBanc”) and IF Bancorp, Inc. (the “Company”) entered into a Contingent Payment Agreement (the “Agreement”) in connection with the classification, and requested renewal by the Company, of certain loan participation interests of Iroquois Federal Savings and Loan Association (the “Bank”), and to establish a specific reserve against such participation interest. The parties entered into an Agreement and Plan of Merger on October 29, 2025 (the “Merger Agreement”) and expect to close the Merger on March 12, 2026, as previously disclosed.

Pursuant to the Agreement, ServBanc and the Company have agreed that the Bank may renew a loan participation interest in the amount of $13,995,617 (the “Loan”) for 120 days, with an additional 60-day extension under certain circumstances (the “Renewal Period”), provided the Bank establishes a specific reserve of $7,000,000 against the Loan. Correspondingly, ServBanc has agreed to deposit $5,004,650 (the “Contingent Payment Fund”), reflecting the tax-effected impact of the reserve on the Company’s tangible common equity, into an account with a contingent payment agent. The Contingent Payment Fund, net of certain expenses, would be disbursed after the closing of the Merger during the Renewal Period, on a pro rata, per share basis, to holders of the Company’s common stock as of the closing date of the Merger only if the Loan is repaid, in part or in full, in excess of the unreserved amount of the Loan within the Renewal Period, as described in greater detail in the Agreement. If the Contingent Payment Fund is not distributed to Company stockholders under the Agreement, such funds, net of certain expenses, will revert to ServBanc. Accordingly, there is no guarantee as to the amount of the Contingent Payment Fund, if any, that may be paid to Company stockholders.

The foregoing summary of the Agreement does not purport to be complete and is qualified in its entirety by reference to the complete text of such document, which is attached hereto as Exhibit 99.1 and is incorporated herein by reference.

ServBanc and the Company have preliminarily agreed upon the tangible common equity calculation of the Company as per the Merger Agreement and, as a result, the cash merger consideration is expected to be $26.40 per share, excluding any payment of the Contingent Payment Fund, if any, to Company stockholders under the Agreement.  If the entire Contingent Payment Fund is paid to Company stockholders, the per share payment would be approximately $1.51 per share, net of estimated expenses associated with the engagement of the contingent payment agent, maintenance of the Contingent Payment Fund account and fees payable to the Company’s financial advisor, Keefe Bruyette and Woods, Inc.
