GREEN BAY, Wis., February 17, 2026—Nicolet Bankshares, Inc. has officially completed its merger with MidWestOne Financial Group, Inc., solidifying a significant expansion in the Upper Midwest banking landscape. The transaction resulted in MidWestOne merging into Nicolet, with Nicolet remaining as the surviving corporate entity.

This strategic combination creates a stronger, more comprehensive financial institution poised to serve a broader customer base across its combined footprint. In the immediate term, MidWestOne Bank will operate as a distinct division within Nicolet National Bank. This interim structure ensures continuity of service for clients and a seamless integration process.

A full operational conversion is scheduled for August 2026. Upon completion of this systems integration, all more than 50 former MidWestOne branch locations will officially adopt the Nicolet brand name. Customers will also gain access to Nicolet’s unified digital banking platform, marking the final step in uniting the two institutions. The merger is positioned to enhance product offerings and community banking strength under a single, cohesive brand.
