Nicolet National Bank and MidWestOne Bank

Why are Nicolet Bank and MidWestOne Bank merging?

This partnership combines our resources and people to serve customers and communities in the Upper Midwest. We believe the best way to meet local needs is through local resources, now more than ever. Working together, we can help make the communities we serve stronger.

What’s not changing?

One thing that will not change with this merger is our focus on staying local. Decisions about banking-related matters and investments in the community will be made by those closest to the customer. Local decision-making is one of the key differences between us and our larger competitors.

When will MidWestOne open as Nicolet National Bank?

MidWestOne will open as Nicolet National Bank on Monday, August 10, 2026.  Since February 13, 2026, MidWestOne Bank has been operating as a division of Nicolet National Bank. We will fully consolidate operations at the end of business on Friday, August 7, 2026, and officially open as Nicolet National Bank on Monday, August 10, 2026.  

Do customers need to do anything right now regarding the upcoming changes?

There is no action required at this time - please continue banking as usual with your current MidWestOne services and branches. If you have additional questions, please contact your local MidWestOne banker, call 1-800-247-4418 or email [email protected]. 

The physical signs on my local branch changed before August 10, 2026, is my branch changing early to Nicolet Bank?
