Green Bay, Wisconsin, April 16, 2024 - Nicolet Bankshares, Inc. (NYSE: NIC) (“Nicolet”) announced first quarter 2024 net income of $28 million and earnings per diluted common share of $1.82, compared to net income of $31 million and earnings per diluted common share of $2.02 for fourth quarter 2024, and net loss of $9 million and loss per diluted common share of $0.61 for first quarter 2023.

Net income reflected certain non-core items and the related tax effect of each, including the first quarter 2023 balance sheet repositioning and third quarter 2023 change in Wisconsin state tax law, as well as gains / (losses) on other assets and investments in all periods. These non-core items positively impacted earnings per diluted common share $0.10 and $0.17 for first quarter 2024 and fourth quarter 2023, respectively, and negatively impacted earnings per diluted common share $2.06 for first quarter 2023.

“Our first quarter results show our focus on execution as we move throughout the year,” said Mike Daniels, Chairman, President, and CEO of Nicolet. “We continue to maintain our relationship-based pricing discipline paired with our credit culture as our team consistently shows the value that we bring. We are encouraged by the results, and we will continue to challenge ourselves to manage both growth and efficiency.”

Daniels continued, “Our strong core profitability has allowed us to build capital, which puts us in an enviable position of having significant options going forward. These options include organic growth, M&A, capital return to shareholders through share buybacks and dividends. While the M&A market remains slow, we are reviewing opportunities and participating in high-level discussions with potential partners, as we maintain our high degree of discipline with our M&A strategy. Our goal is always to partner with a franchise that makes Nicolet and the communities we serve better.”

Nicolet’s 2023 results were significantly impacted by the first quarter 2023 balance sheet repositioning, which included the sale of $500 million (par value) U.S. Treasury held to maturity securities for a pre-tax loss of $38 million or an after-tax loss of $28 million, with the net proceeds used to reduce FHLB borrowings and the remainder held in investable cash. In addition, in July 2023 a new Wisconsin tax law was signed which provided financial institutions with an exemption from state taxable income for interest, fees, and penalties earned on specific loans to existing Wisconsin-based business or agriculture purpose loans. This tax law change to Nicolet moving forward will be a reduction / elimination of State income taxes being expensed; however, it also required a $9.1 million valuation allowance to be established for the State-related deferred tax asset as of the effective date of the legislation. While both provided a drag to 2023 earnings, each also serve as a tailwind for first quarter 2024 and beyond.

Balance Sheet Review

At March 31, 2024, period end assets were $8.4 billion, down slightly ($22 million) from December 31, 2023, mostly lower cash balances, partly offset by growth in loans. Total loans increased $44 million (1%) from December 31, 2023, with growth in agricultural, commercial and industrial, and residential real estate loans. Total deposits of $7.2 billion at March 31, 2024, decreased $32 million from December 31, 2023, mostly noninterest-bearing demand deposits. Total capital was $1.1 billion at March 31, 2024, an increase of $25 million over December 31, 2023, with earnings partly offset by the quarterly common stock dividend.

Asset Quality

Nonperforming assets were $28 million and represented 0.33% of total assets at March 31, 2024, unchanged from December 31, 2023, and down from $41 million or 0.50% at March 31, 2023. The allowance for credit losses-loans was $64 million and represented 1.01% of total loans at March 31, 2024, compared to $64 million (or 1.00% of total loans) at December 31, 2023, and $62 million (or 1.00% of total loans) at March 31, 2023. Asset quality trends remain solid and loan net charge-offs were negligible.

Income Statement Review - Quarter

Net income was $28 million and adjusted net income (non-GAAP) was $26 million for first quarter 2024, compared to net income of $31 million and adjusted net income (non-GAAP) of $28 million for fourth quarter 2023.

Net interest income was $63 million for first quarter 2024, down $1 million from fourth quarter 2023. Interest income increased $1 million mostly due to the repricing of new and renewed loans in a rising interest rate environment, partly offset by lower investable cash balances, while interest expense increased $2 million due to higher average rates on seasonal deposits. The net interest margin for first quarter 2024 was 3.26%, down 4 bps from 3.30% for fourth quarter 2023. The yield on interest-earning assets increased 12 bps (to 5.44%) mostly due to higher average rates from the repricing of the loan portfolio, while the cost of funds increased 11 bps (to 3.01%) for first quarter 2024, attributable mainly to higher cost seasonal deposits.

Noninterest income of $19 million for first quarter 2024 decreased $5 million from fourth quarter 2023, mostly due to the change in net asset gains. First quarter 2024 included net gains of $2 million due to a $1 million gain on sale of an investment security and a $1 million gain on the early extinguishment of subordinated debt, while fourth quarter 2023 included net gains of $6 million from the $9 million pre-tax gain on the sale of Nicolet’s member interest in UFS, LLC, partly offset by a $3 million loss on the sale of certain securities. Excluding the net asset gains (losses), noninterest income for first quarter 2024 was $18 million, a $1 million decrease from fourth quarter 2023, mostly due to changes in the fair value of nonqualified deferred compensation plan assets.

Noninterest expense of $47 million for first quarter 2024 decreased $3 million from fourth quarter 2023. Personnel expense was minimally changed with higher salaries and incentives substantially offset by lower health insurance and a decrease in the fair value of nonqualified deferred compensation plan liabilities. Non-personnel expenses decreased $3 million (12%) between the sequential quarters, mostly lower data processing from an early contract termination charge in fourth quarter 2023.

Use of Non-GAAP Financial Measures

This communication contains non-GAAP financial measures, such as non-GAAP adjusted net income, non-GAAP adjusted 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 or 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. See “Reconciliation of Non-GAAP Financial Measures (Unaudited)” below.

2

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 corporation, 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.

Note: Numbers may not sum due to rounding.

(1)The adjusted 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)Provision expense for 2023 is attributable to the expected loss on a bank subordinated debt investment.

(3)The effective tax rate for periods prior to the July 1, 2023, effective date of the Wisconsin tax law change assumed an effective tax rate of 25%, and periods subsequent to the effective date assumed an effective tax rate of 19.5%.

(4)The adjusted net income reconciliation for first and second quarter 2023 is as originally reported, and has not been restated to reflect the $3 million excess tax expense of those quarters that was subsequently reversed in third quarter 2023 due to the Wisconsin tax law change. Thus, the adjusted net income reconciliation for the quarters of 2023 will not sum to the full year impact.

(5)The ratios of tangible book value per common share, return on average tangible common equity, and tangible common equity to tangible assets exclude goodwill and other intangibles, net. 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.
