IF BANCORP, INC. ANNOUNCES RESULTS FOR FIRST QUARTER

OF FISCAL YEAR 2026 (UNAUDITED)

Watseka, Illinois, October 31, 2025 - IF Bancorp, Inc. (NASDAQ: IROQ) (the “Company”) the holding company for Iroquois Federal Savings and Loan Association (the “Association”), announced unaudited net income of $1.4 million, or $0.43 per basic and diluted share, for the three months ended September 30, 2025, compared to $633,000, or $0.20 per basic and diluted share, for the three months ended September 30, 2024.

“While we are excited about the strategic alliance with ServBank that we announced yesterday, we continue to work hard at improving our financial results. The quarterly results move our profitability in the right direction as demonstrated by the expansion of our net interest margin. The continued repricing of our loan portfolio and funding mix in the current interest rate environment has contributed to the bottom line,” said Walter H. “Chip” Hasselbring, Chief Executive Officer.

For the three months ended September 30, 2025, net interest income was $6.2 million compared to $4.8 million for the three months ended September 30, 2024. Interest income increased to $11.1 million for the three months ended September 30, 2025, from $10.9 million for the three months ended September 30, 2024. Interest expense decreased to $4.9 million for the three months ended September 30, 2025, from $6.1 million for the three months ended September 30, 2024. We recorded a credit to our provision for credit losses of $42,000 in the three months ended September 30, 2025, compared to a provision for credit losses of $382,000 in the three months ended September 30, 2024. Noninterest income decreased to $1.1 million for the three months ended September 30, 2025, from $1.4 million for the three months ended September 30, 2024. Noninterest expense increased to $5.5 million for the three months ended September 30, 2025, from $5.0 million for the three months ended September 30, 2024. For the three months ended September 30, 2025, income tax expense totaled $512,000 compared to $218,000 for the three months ended September 30, 2024.

Total assets at September 30, 2025 were $862.3 million compared to $887.7 million at June 30, 2025. Cash and cash equivalents decreased to $8.0 million at September 30, 2025, from $20.1 million at June 30, 2025. Investment securities increased to $189.8 million at September 30, 2025, from $187.8 million at June 30, 2025. Net loans receivable decreased to $619.3 million at September 30, 2025, from $633.6 million at June 30, 2025. Deposits decreased to $680.3 million at September 30, 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 during the three months ended September 30, 2025, when tax monies were distributed. Total borrowings, including repurchase agreements, increased to $87.3 million at September 30, 2025 from $72.9 million at June 30, 2025. Stockholders’ equity increased to $84.5 million at September 30, 2025 from $81.8 million at June 30, 2025. Equity increased primarily due to a decrease of $1.8 million in accumulated other comprehensive loss , net of tax, net income of $1.4 million, and ESOP and stock equity plan activity of $167,000, partially offset by the accrual of approximately $670,000 in dividends to our stockholders. The decrease in accumulated other comprehensive loss was primarily due to a decrease in unrealized depreciation on available-for-sale securities, net of tax.
