Associated Banc-Corp Reports Second Quarter 2026 Earnings of $0.63 Per Common Share, or $0.73 Per Common Share Excluding Nonrecurring Items Recognized During the Quarter1

Results fueled by sustained organic growth trends, ongoing integration of American National Corporation.

GREEN BAY, Wis. -- July 23, 2026 -- Associated Banc-Corp (NYSE: ASB) ("Associated" or "Company") today reported net income available to common equity ("earnings") of $121 million, or $0.63 per common share, for the quarter ended June 30, 2026. These amounts compare to earnings of $117 million, or $0.70 per common share, for the quarter ended March 31, 2026 and earnings of $108 million, or $0.65 per common share, for the quarter ended June 30, 2025.

The Company's results for the quarter ended June 30, 2026 were impacted by several nonrecurring expenses associated with the acquisition of American National Corporation that closed on April 1, 2026. Excluding the impact of these nonrecurring items, the Company reported adjusted earnings of $140 million, or $0.73 per common share1.

"Organic growth continues to be a primary focus for our company, and midway through 2026, we've maintained our momentum in several important ways," said President & CEO Andy Harmening. "Through June 30th, we've seen double-digit C&I growth, excellent household growth, and strong, improving annual deposit growth--all while maintaining our disciplined approach to expense management and credit. We've also been pleased with the American National partnership, which has largely come in as expected."

"As we look to the back half of 2026 and into 2027, we expect to maintain our growth trajectory through steady execution of organic initiatives and the successful integration of American National Corporation. We look forward to demonstrating our ability to deliver profitable growth sustainably over time."
