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."

This includes any statements regarding management’s plans, objectives, or goals for future operations, products or services, and forecasts of its revenues, earnings, or other measures of performance.

Forward-looking statements are based on current management expectations and, by their nature, are subject to risks and uncertainties. Actual results may differ materially from those contained in the forward- looking statements. Factors which may cause actual results to differ materially from those contained in such forward-looking statements include the ability to integrate the American National Bank (“ANB”) business successfully and in a timely manner; the possibility that the anticipated benefits of the ANB transaction are not realized when expected or at all; the possibility that the ANB transaction may be more expensive to integrate than anticipated; and such other risk factors as identified in the Company’s most recent Form 10-K and subsequent Form 10-Qs and other SEC filings, and such factors are incorporated herein by reference.

Presentation: Within the charts and tables presented, certain segments, columns and rows may not sum to totals shown due to rounding. Non-GAAP measures: This presentation includes certain non-GAAP financial measures. These financial measures have been included as they provide meaningful supplemental information to assess trends in the Corporation’s results of operations. These non-GAAP measures are provided in addition to, and not as substitutes for, measures of our financial performance determined in accordance with GAAP. Our calculation of these non-GAAP measures may not be comparable to similarly titled measures of other companies due to potential differences between companies in the method of calculation.
