On April 1, 2026, the Corporation completed its previously announced acquisition of American National pursuant to the terms of the Merger Agreement by and between Associated and American National.

Pursuant to the Merger Agreement, (i) American National merged with and into Associated Banc-Corp, with Associated Banc-Corp continuing as the surviving corporation, and (ii) following such merger, American National Bank, a national banking association and wholly owned subsidiary of American National, merged with and into the Bank, with the Bank continuing as the surviving bank.

At the effective time of the merger, the outstanding shares of voting common stock and non-voting common stock of American National outstanding immediately prior to the effective time of the merger, other than certain shares held by the Corporation or American National, were converted into the right to receive an aggregate 22,975,382 shares of common stock of the Corporation. This represented 36.250 shares of the Corporation's common stock for each share of outstanding common stock of American National; with cash paid in lieu of fractional shares. Total consideration for the acquisition was $594.1 million valued at the acquisition date fair value of $25.86 per share.

American National operated 33 branches across Nebraska, Minnesota and Iowa, with a concentration in the Greater Omaha and Minneapolis / St. Paul metro markets. As a result of the acquisition, the Corporation will increase its deposit market share and deliver its products and services to an expanded client base across attractive Midwest markets. As of March 31, 2026, American National had total assets of $5.2 billion, total loans of $3.8 billion and total deposits of $4.5 billion.

The acquisition of American National will be accounted for as a business combination using the acquisition method of accounting in accordance with FASB ASC Topic 805, Business Combinations, which requires assets acquired and liabilities assumed to be recognized at fair value as of the acquisition date. Due to the timing of the acquisition, the initial accounting for the acquisition has not been completed. The Corporation expects to finalize the valuation and complete the purchase price allocation as soon as practicable.
