Nicolet Bankshares, Inc. and MidWestOne Financial Group, Inc. Merger Filing Correction

Nicolet Bankshares, Inc. and MidWestOne Financial Group, Inc. filed a joint proxy statement-prospectus for their contemplated merger. An error was identified in the Golden Parachute Compensation table for MidWestOne, specifically in the "Total" column on page 74. While the amounts in the first three columns were accurate, the "Total" column did not correctly sum these values. The filing provides the corrected "Merger-Related Compensation for MidWestOne Named Executive Officers" table, detailing estimated compensation, including cash and equity awards, and benefits for executives like Charles N. Reeves III, Len D. Devaisher, Barry S. Ray, Paul A. Ho-Sing-Loy, and Gary L. Sims. The corrected table reflects updated calculations based on a presumed merger closing date of February 13, 2026, and other specified assumptions regarding employment termination and share price. The filing also reiterates important information about the merger, where to find additional details, and the participants in the solicitation process.
