MidWestOne Bank Enters Merger Agreement with Nicolet Bank

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.

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 the combined company and our larger competitors.

After the close of business on February 13, 2026, MidWestOne will operate as a division of Nicolet National Bank. This means we will be under one ownership while continuing to operate separately until later in the year, when we will consolidate operations into Nicolet National Bank. Our name between our legal close date of February 13 and the operational consolidation will be “MidWestOne, a Division of Nicolet National Bank.” Once we have completely consolidated the two companies we will be known as Nicolet National Bank. You’ll start seeing the name change throughout 2026.

As we draw closer to the operational merger later in 2026, you will receive information from Nicolet National Bank about your products and services, and what will happen next when we become one bank. Until then, there is no action needed on your part.

We will share updates as soon as changes are finalized and confirmed. Transparency and communication are priorities throughout this process.

Any time you have questions, please reach out. If your specific banker is not available, you can always contact the Service Center at 800.247.4418.

We are in the early stages of the merger, and any decisions affecting customer accounts will be communicated clearly and with advanced notice. There is no customer action required at this time.
