IF Bancorp, Inc. (NASDAQ: IROQ) (the “Company”) the holding company for Iroquois Federal Savings and Loan Association (the “Association”), announced unaudited net income of $1.3 million, or $0.41 per basic and diluted share, for the three months ended December 31, 2025, compared to net income of $1.2 million, or $0.38 per basic and diluted share, for the three months ended December 31, 2024.

Walter H. “Chip” Hasselbring, III, Chairman and Chief Executive Officer, commented, “We continue to execute on our business plan and are pleased with our results for the quarter. As previously announced, we are excited about our pending merger with ServBanc. The transaction remains on track for a first quarter close as previously reported.”

For the three months ended December 31, 2025, net interest income was $6.0 million compared to $5.0 million for the three months ended December 31, 2024. We recorded a provision for credit losses of $34,000 for the three months ended December 31, 2025, compared to a credit for credit losses of $450,000 for the three months ended December 31, 2024.

Noninterest income increased to $1.4 million for the three months ended December 31, 2025, from $1.3 million for the three months ended December 31, 2024. Noninterest expense increased to $5.5 million for the three months ended December 31, 2025, from $5.0 million for the three months ended December 31, 2024. The largest component of this increase was professional services, which increased primarily due to additional legal and consulting services received as a result of the pending merger with ServBanc Holdco, Inc. Provision for income tax increased to $494,000 for the three months ended December 31, 2025, from $463,000 for the three months ended December 31, 2024.

The Company announced unaudited net income of $2.7 million, or $0.84 per basic and diluted share for the six months ended December 31, 2025, compared to $1.9 million, or $0.57 per basic and diluted share for the six months ended December 31, 2024. For the six months ended December 31, 2025, net interest income was $12.2 million compared to $9.8 million for the six months ended December 31, 2024. We recorded a credit for credit losses of $8,000 for the six months ended December 31, 2025, compared to a credit for credit losses of $68,000 for the six months ended December 31, 2024.

Deposits decreased to $649.6 million at December 31, 2025, from $721.3 million at June 30, 2025. The large decrease in deposits was due to approximately $59.3 million in deposits from a public entity that collects real estate taxes that were withdrawn in the six months ended December 31, 2025, when tax monies were distributed. Total borrowings, including repurchase agreements, increased to $83.6 million at December 31, 2025 from $72.9 million at June 30, 2025. Stockholders’ equity increased to $87.4 million at December 31, 2025 from $81.8 million at June 30, 2025. Equity increased primarily due to net income of $2.7 million, an increase of $3.1 million in accumulated other comprehensive income (loss), net of tax, and employee stock ownership plan (“ESOP”) and stock equity plan activity of $339,000, partially offset by the accrual of approximately $647,000 in dividends to our shareholders.

On October 29, 2025, the Company announced the signing of a merger agreement under which ServBanc Holdco, Inc. will acquire the Company in an all-cash transaction for total consideration valued at approximately $89.8 million, subject to certain potential adjustments described in the merger agreement. Subject to the satisfaction or waiver of the closing conditions contained in the merger agreement, including the approval of the merger agreement by the Company’s shareholders, it is expected that the merger will be completed during the first quarter of 2026. However, it is possible that factors outside the control of both companies could result in the merger being completed at a different time or not at all.
