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.

What is different?
MidWestOne Bank’s privacy notice indicated that there is no sharing with affiliates for everyday business purposes and marketing. Nicolet’s privacy notice indicates that we do share with affiliates.

How is information shared?
Nicolet uses one centralized CRM system. Customer information is stored in this system and is accessible by all departments of Nicolet. Because multiple divisions can view and use this information, it is considered sharing under privacy regulations.
Sharing information in one internal system helps us keep accounts running smoothly, follow the law, and offer products and services. The purpose is to provide the best service possible, by providing all bankers access to critical information. We share info with our Nicolet teams for everyday banking, marketing services, and with partner companies.
Why does Nicolet share?
So that we understand our entire customer relationship. We don’t use the information for “cold calling”. We use the information to make sure we are prepared to meet all of our customers’ banking needs.
If I want to opt out of information sharing, what should I do?
You can opt out by completing the form included in your privacy notice and mailing it to the address provided. You may also visit any MidWestOne branch, where our team will be happy to assist you and record your opt‑out request. If you choose to opt out, we may have a more limited view of your relationship, which can affect our ability to serve you effectively.
