Nicolet Bankshares, Inc. (NYSE:NIC) ("Nicolet") announced it had been added to the KBW Nasdaq Regional Bank Index (Index Ticker: KRX) as part of its first quarter 2026 index rebalancing.

"It is an honor to be included in the KBW Nasdaq Regional Bank Index," said Mike Daniels, Chairman, President and Chief Executive Officer of Nicolet. "This recognition represents another significant milestone in our 25‑year journey, which began with a single office in downtown Green Bay and has grown into a leading community banking franchise across the Upper Midwest, with more than $15 billion in assets and 100 locations. Given that Nicolet has never completed a traditional initial public offering or raised capital in the public markets, this achievement is particularly meaningful. I am deeply grateful to our employees, directors, customers, and the communities we serve, as well as to KBW and Nasdaq for this recognition."

The KBW Nasdaq Regional Banking Index is a modified market capitalization weighted index designed to track the performance of U.S. regional banks and thrifts that are publicly traded in the U.S. The compilation, maintenance, and calculation of the KRX Index are the responsibility of Nasdaq and Keefe, Bruyette & Woods, Inc., a wholly owned subsidiary of Stifel Financial Corp. (NYSE:SF). For more information on the KBW Nasdaq Regional BankingIndex, please visit kbw.com.
