Effective February 13, 2026, Nicolet Bankshares, Inc. ("Nicolet" or the "Company") completed its previously announced merger (the "Merger") with MidWest*One* Financial Group, Inc. ("MidWest*One*"), pursuant to the terms of the Agreement and Plan of Merger, dated October 23, 2025, by and between Nicolet and MidWest*One* (the "Merger Agreement"). At closing, MidWest*One* merged with and into Nicolet, with Nicolet surviving the Merger. Immediately following the Merger, MidWest*One*'s wholly owned bank subsidiary, MidWest*One* Bank, merged with and into Nicolet's wholly owned bank subsidiary, Nicolet National Bank (the "Bank") pursuant to the terms of a Plan of Merger by and between the Bank and MidWest*One* Bank. Item 1.01 of the Current Report on Form 8-K dated October 23, 2025, and filed by Nicolet with the U.S. Securities and Exchange Commission on October 23, 2025 (the "Prior Form 8-K") reporting the entry into the Merger Agreement is incorporated by reference.

Pursuant to the terms and conditions set forth in the Merger Agreement, at the effective time of the Merger (the "Effective Time"), each share of MidWestOne common stock issued and outstanding immediately prior to the Effective Time was converted into the right to receive 0.3175 shares of Nicolet common stock.

As a result of the Merger, Nicolet issued approximately 6.6 million shares of Nicolet common stock, valued at $155.19 per share based on the closing stock price of Nicolet's common stock on the New York Stock Exchange on February 13, 2026.

The eight Nicolet directors selected are as follows: Michael E. Daniels, Robert B. Atwell, John N. Dykema, Donald J. Long, Jr., Oliver Pierce Smith, Susan L. Merkatoris, Glen E.

**FOR IMMEDIATE RELEASE**

**Nicolet Bankshares, Inc. Completes Merger with MidWest*One* Financial Group, Inc.**

**GREEN BAY, WI, February 17, 2026–** Nicolet Bankshares, Inc. (NYSE: NIC) ("Nicolet") completed its merger with MidWest*One* Financial Group, Inc., ("MidWest*One*"), as a result of which, MidWest*One* merged with and into Nicolet, with Nicolet being the surviving corporation. MidWest*One* Bank will operate as a division of Nicolet National Bank until the planned system conversion in August 2026. At that time, all 50+ MidWest*One* locations will transition to the Nicolet brand and digital banking platform, expanding Nicolet's presence in Iowa, the Twin Cities, Western Wisconsin, and Denver.

Based on initial financial data, the addition of MidWest*One* added approximately $6 billion in assets to increase Nicolet's total assets to approximately $15 billion. Total loans of the combined company will increase to approximately $11 billion and total deposits will increase to approximately $13 billion.
