NICOLET BANKSHARES, INC. ANNOUNCES THIRD QUARTER 2024 RESULTS

•Net income $33 million for third quarter 2024, compared to net income of $29 million in prior quarter, and net income of $17 million for third quarter 2023

•Net income of $90 million or adjusted net income (non-GAAP) of $87 million for the first nine months of 2024, compared to net income of $31 million or adjusted net income (non-GAAP) of $73 million for the first nine months of 2023

•Tangible common equity to tangible assets increased 64 bps to 9.21% at quarter end due to strong core earnings and a significant reduction in unrealized losses in the securities portfolio from lower expected interest rates

•Asset quality remains solid, as nonperforming assets declined to 31 bps – the lowest level in more than three years; annualized net charge-offs remain negligible at 2 bps of loans

Green Bay, Wisconsin, October 15, 2024 - Nicolet Bankshares, Inc. (NYSE: NIC) (“Nicolet”) announced third quarter 2024 net income of $33 million and earnings per diluted common share of $2.10, compared to net income of $29 million and earnings per diluted common share of $1.92 for second quarter 2024, and net income of $17 million and earnings per diluted common share of $1.14 for third quarter 2023. Net income for the nine months ended September 30, 2024 was $90 million and earnings per diluted common share of $5.84, compared to net income of $31 million and earnings per diluted common share of $2.05 for the nine months ended September 30, 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 detailed in the Reconciliation of Non-GAAP Financial Measures table below), as well as gains / (losses) on other assets and investments in all periods. For the nine months ended September 30, 2024, these non-core items positively impacted earnings per diluted common share $0.19, and negatively impacted earnings per diluted common share $2.82 for the nine months ended September 30, 2023.

“The third quarter produced strong results across all revenue lines, and demonstrated what happens when almost 1,000 people show up every day to make a difference,” said Mike Daniels, Chairman, President, and CEO of Nicolet. “Financial results were impressive with quarterly return on average assets of 1.50% and return on average tangible common equity of 17.77%. We saw growth in loans and core deposits. Revenue was up across wealth, mortgage, and all other fee income areas. And our net interest margin continued its upward trajectory as we were able to keep deposit and funding costs relatively stable during the quarter.”

“Furthermore, our credit quality remains exceptional as nonperforming assets fell to their lowest level in years. This not only speaks to the team’s ability to execute within Nicolet’s consistent credit culture, but also to the strength and resilience of our commercial customer base across the Upper Midwest. Despite facing higher interest rates, rising input costs due to inflation, and the challenges of finding qualified workers, our customers have shown their ability to adapt in this economy. Nicolet’s message of shared success is resonating within our walls and in the communities we serve,” Daniels continued.

Balance Sheet Review

At September 30, 2024, period end assets were $8.6 billion, an increase of $80 million (1%) from June 30, 2024, mostly from loan growth and improvements in the fair value of the available for sale securities portfolio. Total loans increased $28 million from June 30, 2024, while the securities portfolio increased $26 million from June 30, 2024, mostly due to the positive fair value movements. Total deposits of $7.3 billion at September 30, 2024, increased $19 million from June 30, 2024, the net of a $75 million increase in noninterest-bearing demand and a $56 million decrease in interest-bearing deposits. Total capital was $1.1 billion at September 30, 2024, an increase of $58 million over June 30, 2024, with solid earnings and improvements in the securities portfolio valuation partly offset by the quarterly common stock dividend.

Asset Quality

Nonperforming assets were $26 million and represented 0.31% of total assets at September 30, 2024, compared to $29 million or 0.34% of total assets at June 30, 2024, and $32 million or 0.37% of total assets at September 30, 2023. The allowance for credit losses-loans was $66 million and represented 1.00% of total loans at September 30, 2024, compared to $65 million (or 1.00% of total loans) at June 30, 2024, and $63 million (or 1.01% of total loans) at September 30, 2023. Asset quality trends remain solid and loan net charge-offs were negligible.

Income Statement Review - Quarter

Net income was $33 million for third quarter 2024, compared to net income of $29 million for second quarter 2024.

Net interest income was $68 million for third quarter 2024, up $3 million from second quarter 2024. Interest income increased $4 million mostly due to the repricing of new and renewed loans in a higher interest rate environment, as well as solid loan growth, while interest expense increased $1 million due to both higher average balances and higher rates. The net interest margin for third quarter 2024 was 3.44%, up 9 bps from 3.35% for second quarter 2024. The yield on interest-earning assets increased 7 bps (to 5.68%) mostly due to higher average rates from the repricing of the loan portfolio, while the cost of funds increased 2 bps (to 3.11%) for third quarter 2024.

Noninterest income of $22 million for third quarter 2024 increased $3 million over second quarter 2024, with increases in most noninterest income categories. Wealth income increased $0.4 million on growth in assets under management (due to both net new accounts and positive fair value changes), while net mortgage income grew $0.2 million mostly from higher gains on sale. Net asset gains and deferred compensation plan asset market valuations during third quarter 2024 were attributable to positive movements in the market.

Noninterest expense of $49 million for third quarter 2024 increased $2 million over second quarter 2024. Personnel expense increased $3 million over second quarter 2024, including higher incentives commensurate with solid earnings, higher salaries, and the offsetting market value change in the deferred compensation plan liabilities. Non-personnel expenses combined decreased $0.4 million from second quarter 2024 on lower marketing (due to timing of marketing campaigns) and lower other noninterest expense (due to the board equity retainer granted in second quarter), partly offset by higher data processing.

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 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. See “Reconciliation of Non-GAAP Financial Measures (Unaudited)” below. 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.

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)Includes the gains / (losses) on other assets and investments, as well as the impact of the March 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.

(4)In July 2023, a new Wisconsin tax law change 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. The effective tax rate for periods prior to the July 1, 2023, effective date of this 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%. 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.
