Two founders build a Green Bay bank
Mike Daniels and Bob Atwell founded Nicolet in 2000. Its annual report says Nicolet National Bank opened for business in Green Bay on November 1, following its organization as a national bank. The FDIC records October 31, 2000 as its establishment date. These adjacent dates distinguish the charter record from the first day of business. [1][3][4]
The insured institution is Nicolet National Bank, certificate 57038. Nicolet Bankshares, Inc. is the public holding company. Daniels became the bank’s president and chief executive in 2016, took those roles at the parent in 2021 and added the chairman’s role in 2024. In September 2025, the board announced that his planned leadership would extend through the end of 2030. [3]
Local lending expands through acquisitions
Nicolet’s annual report describes ten completed acquisitions from 2012 through the end of 2025, supplementing growth within the existing business. By year-end 2025 it operated 57 branches. Its services span business deposits and cash management, commercial-property and construction financing, home loans and consumer banking. Agricultural lending is a substantial part of its community-bank model. [4]
The parent also owned Nicolet Advisory Services, LLC, which provided brokerage and investment-advisory services, and Nicolet Insurance Services, LLC, which supported crop insurance associated with agricultural lending. These companies broaden the customer relationship but are separate from the national-bank charter. Retirement-plan services and trust work also make the franchise more than a collection of loan balances. [4]
MidWestOne changes the scale of the business
On February 13, 2026, Nicolet completed the acquisition of MidWestOne Financial Group, Inc. The acquired company brought $6.1 billion of assets, $4.4 billion of loans and $5.3 billion of deposits at acquisition, according to Nicolet’s July earnings release. The February 17 completion announcement described MidWestOne Bank as a division of Nicolet National Bank pending a planned systems conversion. [5][6]
The addition expanded the bank’s presence in Iowa, the Twin Cities and western Wisconsin, and initially brought Denver locations as well. Four former MidWestOne directors joined the boards of Nicolet and the bank. This was a major change in the operating footprint and governance, not simply loan growth within the old Green Bay franchise. [5]
The Denver branches take a different path
Nicolet subsequently agreed to sell the Denver branches acquired in the transaction to Sunwest Bank. Its July 21 results still described the sale as expected to close in the third quarter and reported approximately $402 million of loans and $388 million of deposits at those locations on June 30. Those were dated branch balances, not the eventual purchase price. [6]
On July 29, 2026, Sunwest announced completion of the acquisition of the former MidWestOne and Bank of Denver branches from Nicolet. The newer release resolves the earlier pending status. The Denver operations therefore should not be treated as a permanent part of Nicolet’s post-merger branch map. [7]
A full quarter exposes the integration economics
Nicolet Bankshares reported $57 million of net income for the second quarter of 2026, compared with $15 million for the first. Its separately labeled, non-GAAP core net income figures were $65 million and $52 million. The parent said the net interest margin benefited from a full quarter of acquisition-related loan-accounting income and lower core-deposit funding costs. [6]
A bigger acquired loan book, purchase-accounting effects and integration costs make the 2026 comparison different from a year of purely internal growth. In July, management still discussed completing the systems conversion later in the summer. The sources reviewed here establish the merger and the Denver sale; they do not independently establish the exact completion date of every customer-system conversion. [5][6][7]
The insured bank at June 30
At June 30, 2026, the FDIC reported $15.391 billion of assets, $12.950 billion of deposits, $11.136 billion of net loans and leases, and $2.302 billion of equity for the insured bank. Net income was $78.117 million for the first six months of 2026. These bank-only figures are converted from thousands of dollars; income is year to date, not standalone second-quarter profit. [2]
Agricultural-production loans were $0.571 billion and loans secured by farmland were $1.195 billion. These separate categories show the significance of farming to the bank’s lending. The FDIC snapshot precedes the July Denver sale and should not be presented as the balance sheet after that divestiture. [2][7]
