GREEN BAY, Wis.--(BUSINESS WIRE)--Apr. 21, 2026-- Nicolet Bankshares, Inc. (NYSE: NIC) (“Nicolet”) announced net income of $15 million and earnings per diluted common share of $0.81 for first quarter 2026, compared to net income of $33 million and earnings per diluted common share of $2.08 for first quarter 2025 and net income of $40 million and earnings per diluted common share of $2.65 for fourth quarter 2025. Net income included certain non-core items, mostly merger-related expenses, that negatively impacted earnings per diluted common share $1.94 for first quarter 2026, resulting in core diluted earnings per common share (non-GAAP) of $2.75.

On February 13, 2026, Nicolet completed its acquisition of MidWestOneFinancial Group, Inc. (“MidWestOne”), creating one of the largest community banks in the Upper Midwest. MidWestOne shareholders received 0.3175 shares of Nicolet common stock for each share of MidWestOne common stock owned, resulting in the issuance of approximately 6.6 million shares of Nicolet common stock valued at $1.0 billion (based upon the closing stock price of Nicolet’s common stock on February 13, 2026). Upon consummation, MidWestOne added total assets of $6.1 billion, loans of $4.4 billion, deposits of $5.3 billion, and preliminary goodwill of approximately $0.5 billion to Nicolet’s balance sheet.

Evaluation of financial performance and balance sheet line items is impacted both by the timing and size of the MidWestOne acquisition. Certain income statement results, average balances, and related ratios for 2026 include partial contributions from MidWestOne from the acquisition date.

“This quarter reflects disciplined execution through a period of transformational growth,” said Mike Daniels, Chairman, President, and CEO of Nicolet. “We delivered solid core earnings, expanded margins, and increased tangible book value with no material per share dilution in book value from the MidWestOne acquisition. Also, our strong profitability allows us to continue to return capital to shareholders through a 13% increase in our dividend as well as restarting our share repurchase program during the quarter. All of this occurred while completing a transaction that we believe strengthens Nicolet’s competitive position and long-term shared success returns to our Three Circles.”

Daniels continued, “The integration continues as planned with no surprises and I am continually encouraged by the alignment between our teams. Our core conversion is currently scheduled for late summer, after which all anticipated cost savings should be realized and we look to return to our regular position of producing top decile core profitability.”

Balance Sheet Review
At March 31, 2026, period end assets were $15.6 billion, an increase of $6.4 billion from December 31, 2025, largely due to the acquisition of MidWestOne, which added $6.1 billion of total assets at acquisition. Total loans increased $4.0 billion from December 31, 2025, with MidWestOne adding loans of $4.4 billion at acquisition. Total deposits of $12.6 billion at March 31, 2026, increased $4.9 billion from December 31, 2025, also largely due to the acquisition of MidWestOne. Total capital was $2.3 billion at March 31, 2026, an increase of $1.0 billion over December 31, 2025, mostly due to the acquisition of MidWestOne.

Asset Quality
Nonperforming assets were $79 million and represented 0.51% of total assets at March 31, 2026, compared to $32 million and 0.35% of total assets at December 31, 2025, with the increase largely due to the MidWestOne acquisition. The allowance for credit losses-loans was $133 million and represented 1.23% of total loans at March 31, 2026, compared to $69 million (or 1.01% of total loans) at December 31, 2025, with the increase mostly due to the allowance increase from the acquisition of MidWestOne. Asset quality trends remain solid and loan net charge-offs were negligible.

Income Statement Review - Quarter
Net income was $15 million for first quarter 2026, compared to net income of $40 million for fourth quarter 2025.

Net interest income was $110 million for first quarter 2026, $29 million (35%) higher than fourth quarter 2025, the net of a $38 million increase in interest income and a $9 million increase in interest expense. Average interest-earning assets of $11.2 billion were up $2.9 billion from fourth quarter 2025, with higher average loans (up $2.3 billion) and higher average securities (up $578 million), mostly due to the MidWestOne acquisition. Average interest-bearing liabilities of $8.4 billion were up $2.4 billion from fourth quarter 2025, mostly due to higher average interest-bearing deposits (up $2.4 billion) acquired with MidWestOne.

The net interest margin for first quarter 2026 was 3.98%, compared to 3.86% for fourth quarter 2025. The yield on interest-earning assets increased 1 bp (to 5.73%), while the cost of interest-bearing liabilities for first quarter 2026 decreased 25 bps (to 2.36%).

Noninterest income was $25 million for first quarter 2026, up $2 million compared to fourth quarter 2025. Excluding net asset gains (losses), noninterest income was up $3 million, including a $2 million increase in wealth management fee income and a $1 million increase in service charges on deposit accounts, both mostly due to the MidWestOne acquisition. Net asset losses were $1 million for first quarter 2026 (comprised primarily of a write-down on an equity investment), compared to nominal net asset gains for fourth quarter 2025.

Noninterest expense was $110 million for first quarter 2025, a $57 million increase from fourth quarter 2025, mostly due to a $39 million increase in merger-related expense. Personnel expense increased $8 million from fourth quarter 2025, reflecting the larger employee base post-acquisition. Non-personnel expense increased $49 million from fourth quarter 2025, and included the increase in merger-related expense, as well as higher overall expense for a larger operating base.

Subsequent Event
Nicolet National Bank has entered into a definitive purchase and assumption agreement to sell its Denver, Colorado banking branches (acquired in the MidWestOne transaction) to Sunwest Bank. This transaction is an all-cash deal that has been approved by the respective boards of directors, and is expected to close in third quarter 2026, subject to regulatory approval and other standard closing conditions. As of March 31, 2026, the Denver locations had total loans of approximately $390 million and deposits of approximately $380 million. Hovde Group, LLC served as financial adviser and Nelson Mullins Riley & Scarborough LLP provided legal counsel to Nicolet.

Use of Non-GAAP Financial Measures
This communication contains non-GAAP financial measures, such as core net income, core earnings per diluted common share, tangible book value per common share, return on average tangible common equity, and tangible common equity to tangible assets. Management believes such measures to be helpful to management, investors and others in understanding Nicolet’s results of operations and financial position. When non-GAAP financial measures are used, the comparable GAAP financial measures, as well as the reconciliation of the non-GAAP measures to the GAAP financial measures, are provided.

The non-GAAP net income measure and related reconciliation provide information useful to investors in understanding the operating performance and trends of Nicolet and also aid investors in comparing Nicolet’s financial performance to the financial performance of peer banks. Management considers non-GAAP financial ratios to be critical metrics with which to analyze and evaluate financial condition and capital strengths. While non-GAAP financial measures are frequently used by stakeholders in the evaluation of a company, they have limitations as analytical tools and should not be considered in isolation or as a substitute for analyses of results as reported under GAAP.
