A Green Bay community bank that doubled in size by buying MidWestOne in February 2026; it has not disclosed an AI programme and treats AI in its 10-K as a cyber, fraud and competition risk.
How is Nicolet National Bank using AI?
Nicolet Bankshares, the Green Bay, Wisconsin parent of Nicolet National Bank (about $15.4 billion in lead-bank assets at June 30, 2026), has not disclosed an AI programme. Its 2025 10-K, filed on February 27, 2026, mentions artificial intelligence only among risks: new technologies such as AI 'present new and significant cybersecurity safety risks that must be analyzed and addressed before implementation', AI and quantum computing could worsen card, check and social-engineering fraud, and companies offering AI-based applications are beginning to compete directly in personal financial advice. The bank's attention in 2026 has been its acquisition of MidWestOne Financial Group, announced in October 2025 and closed on February 13, 2026, adding about $6 billion of assets; it sold MidWestOne's Denver branches to Sunwest Bank and planned a core conversion for the summer of 2026, after which CEO Mike Daniels expects the planned cost savings. No AI tool, vendor, use case, budget or executive has been named.
Thin public record: No AI programme, tool, vendor or AI leader on the public record; the 10-K's AI passages are generic risk factors and 2026 disclosures concern the MidWestOne merger and its core conversion.

What does the public record suggest about Nicolet's AI strategy?
Analysis by BankingNewsAI from the sources cited on this page. Observations, not advice.
01
A merger year, not an AI year
Nicolet's 2026 disclosures are about closing and converting MidWestOne; AI tools, if adopted, are likely to arrive with the post-conversion platform rather than before it.
02
A cautious stance on paper
Requiring cybersecurity analysis 'before implementation' is a gatekeeping statement; it reads as a bank that has not yet put AI into material use, or has not chosen to say so.
03
Crossing $10 billion raises the bar
At more than $15 billion, Nicolet now faces closer supervisory attention to model risk and third-party oversight, which would apply to any AI it introduces.
