FIRST BUSEY CORP /NV/

On December 4, 2025, the First Busey Corporation (“Busey”) board of directors approved an amendment to Busey’s previously adopted share repurchase program to increase the number of shares of Busey’s common stock available for repurchase by 4,000,000 shares. As of the close of business on December 4, 2025, under the amended share repurchase program, Busey is now authorized to repurchase, from time to time as Busey deems appropriate, up to a remaining number of 5,454,275 shares of Busey's common stock. Repurchases may be made in the open market, through block trades or otherwise, and in privately negotiated transactions. The repurchase program does not obligate Busey to repurchase any dollar amount or number of shares. The repurchase program has no expiration date, and may be expanded, modified, suspended, or discontinued by Busey's board of directors at its discretion at any time.
