You will soon see the familiar shades of Nicolet National Bank’s green and white in Iowa.

Nicolet Bankshares Inc. announced Wednesday that it has completed its merger with Iowa City-based MidWestOne Financial Group Inc., adding more than 50 locations in Iowa to its brand and digital banking platform by August 2026.

The merger creates one of the largest community-owned banks in the country, with pro forma total assets of $15.3 billion, deposits of $13.1 billion and loans of $11.3 billion. Once fully integrated, Nicolet National Bank will have 110 branches, primarily across the Upper Midwest.

Nicolet National Bank has several locations in Door and Kewaunee counties.

“We are excited to announce the acquisition of MidWestOne and welcome their employees, customers and shareholders to Nicolet,” said Mike Daniels, chairman, president and CEO of Nicolet, when the merger was first announced in October. “We view the people at MidWestOne as true kindred spirits in our approach to serving customers, communities and employees. They have been stalwarts of the community for over 90 years, and we intend to be great stewards of that legacy.”

Daniels added the acquisition will make the bank stronger as it approaches its 25th anniversary.

The move follows other recent acquisitions, including Community Investors Bank in 2021 and Charter Bankshares in 2022.
