GREEN BAY, Wis.--(BUSINESS WIRE)--Nicolet Bankshares, Inc. (NYSE: NIC) (“Nicolet”) announced net income of $57 million and earnings per diluted common share of $2.62 for second quarter 2026, compared to net income of $15 million and earnings per diluted common share of $0.81 for first quarter 2026, and net income of $36 million and earnings per diluted common share of $2.34 for second quarter 2025. Net income included certain non-core items, mostly merger-related expenses, that negatively impacted earnings per diluted common share $0.37 for second quarter 2026 and $1.94 for first quarter 2026, resulting in core diluted earnings per common share (non-GAAP) of $2.99 and $2.75, respectively.

“Our second quarter results reflect the strength of the Nicolet model and the disciplined execution of our team,” said Mike Daniels, Chairman, President, and CEO of Nicolet. “Core earnings remained strong, net interest margin expanded, credit quality continued to perform well, allowing us to repurchase stock throughout the quarter, and tangible book value increased. I’m particularly pleased with the progress we’ve made integrating MidWestOne. Throughout the process, our teams have remained focused on serving our clients while executing our integration plan. As we complete our conversion later this summer and begin fully realizing our planned cost savings, we’ll be in a stronger position to restore the high level of profitability and returns that have historically defined Nicolet.”

Daniels added, “From a balance sheet perspective, we continued to improve the composition of both our loan and deposit portfolios during the quarter. While period-end balances were relatively stable, we continue to see a shift toward higher-yielding in-market commercial loans, supported by growth in lower-cost core deposits. This combined with the momentum we’re seeing across our markets and the opportunities we’ve created in Iowa and Minnesota, those trends support continued margin expansion and position us well to deliver solid organic growth through the balance of 2026.”

Nicolet’s financial performance and certain balance sheet line items were impacted by the timing and size of the MidWestOne Financial Group, Inc. (“MidWestOne”) acquisition on February 13, 2026. Certain income statement results, average balances, and related ratios for 2026 include partial contributions from MidWestOne from the acquisition date. At acquisition, MidWestOne added total assets of $6.1 billion, loans of $4.4 billion, and deposits of $5.3 billion.

Balance Sheet Review

At June 30, 2026, period end assets were $15.4 billion, a decrease of $160 million from March 31, 2026, largely due to lower cash and cash equivalents. Total loans decreased $32 million from March 31, 2026, while investments grew $20 million. Total deposits of $12.5 billion at June 30, 2026, decreased $101 million from March 31, 2026, including a $100 million decrease in brokered deposits and a $1 million decrease in core deposits. Long-term borrowings decreased $87 million from the prior quarter due to the early redemption of junior subordinated debentures. Total capital was $2.3 billion at June 30, 2026, an increase of $15 million over March 31, 2026, with earnings offset by common stock repurchases and the quarterly common stock dividend.

Asset Quality

Nonperforming assets were $75 million and represented 0.49% of total assets at June 30, 2026, compared to $79 million (0.51% of total assets) at March 31, 2026. The allowance for credit losses-loans was $134 million and represented 1.23% of total loans at June 30, 2026, compared to $133 million (or 1.23% of total loans) at March 31, 2026. Asset quality trends remain solid and loan net charge-offs were negligible.

Income Statement Review - Quarter

Net income was $57 million for second quarter 2026, compared to net income of $15 million for first quarter 2026.

Net interest income was $141 million for second quarter 2026, $32 million (29%) higher than first quarter 2026, the net of a $43 million increase in interest income and an $11 million increase in interest expense. Average interest-earning assets of $13.9 billion were up $2.6 billion from first quarter 2026, with higher average loans (up $2.1 billion) and higher average securities (up $567 million), mostly due to the inclusion of a full quarter of MidWestOne balances. Average interest-bearing liabilities of $10.4 billion were up $2.0 billion from first quarter 2026, also attributable to a full quarter of MidWestOne balances.

The net interest margin for second quarter 2026 was 4.14%, compared to 3.98% for first quarter 2026, with a portion of the increase attributable to loan purchase accounting accretion (which added 23 bps and 18 bps to second and first quarter net interest margin, respectively). The yield on interest-earning assets increased 13 bps (to 5.86%), including an 8 bps increase in loan yield (to 6.26%) as well as a higher investment yield from the discount accretion on the early call of a municipal bond and a full quarter of purchase accretion. On the funding side, the cost of interest-bearing liabilities for second quarter 2026 decreased 7 bps (to 2.29%), benefitting from a full quarter of the lower core deposit funding costs from MidWestOne.

Noninterest income was $36 million for second quarter 2026, up $11 million compared to first quarter 2026. Excluding net asset gains (losses), noninterest income was up $8 million, including a $1 million increase in wealth management fee income, a $1 million increase in service charges on deposit accounts, and a $2 million increase in card interchange income, all mostly due to the MidWestOne acquisition. Net asset gains were $2 million for second quarter 2026 (mostly due to favorable market valuations on an equity investment), compared to net asset losses of $1 million for first quarter 2026 (comprised primarily of a write-down on an equity investment).

Noninterest expense was $104 million for second quarter 2026, a $6 million decrease from first quarter 2026, mostly due to a $33 million decrease in merger-related expense offset by a full quarter of MidWestOne expenses. Personnel expense increased $12 million from first quarter 2026, reflecting the larger employee base post-acquisition. Non-personnel expense decreased $18 million from first quarter 2026, and included the decrease in merger-related expense, offset by higher overall expense for a full quarter of the larger operating base and a $5 million loss on the early redemption of junior subordinated debentures.

Sale of Denver Branches

On April 21, 2026, Nicolet National Bank 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, has received regulatory approval, and is expected to close in third quarter 2026, subject to standard closing conditions. As of June 30, 2026, the Denver locations had total loans of approximately $402 million and deposits of approximately $388 million.

Declaration of Quarterly Cash Dividend to Shareholders

On July 21, 2026, Nicolet’s Board of Directors declared a quarterly cash dividend of $0.36 per share to holders of its common stock. The dividend is payable on September 15, 2026, to shareholders of record as of September 1, 2026.

Next Quarterly Earnings Release

Nicolet expects to issue the third quarter 2026 earnings release on October 20, 2026.

(1)	The core net income measure and related reconciliation provide information useful to investors in understanding the operating performance and trends of Nicolet and also to aid investors in the comparison of Nicolet’s financial performance to the financial performance of peer banks.
(2)	Includes the provision expense for the ACL on unfunded commitments related to the MidWestOne merger.
(3)	Assumes an effective tax rate of 21.5% for 2026 and 19.5% for 2025.
(4)	The ratios of core return on average assets and core return on average common equity use core net income as the numerator in place of net income (GAAP).  These financial metrics have been included as they provide information useful to investors in understanding the operating performance and trends of Nicolet.
(5)	The ratios of tangible book value per common share, return on average tangible common equity, core return on average tangible common equity, and tangible common equity to tangible assets exclude goodwill and other intangibles, net. In addition, the ratios of return on average tangible common equity and core return on average tangible common equity remove the intangibles amortization, net of tax, from the numerator.  These financial ratios have been included as they are considered to be critical metrics with which to analyze and evaluate financial condition and capital strength.
