NICOLET BANKSHARES, INC.

Notes to Unaudited Consolidated Financial Statements

Note 1 – Basis of Presentation

General

In the opinion of management, the accompanying unaudited consolidated financial statements contain all adjustments necessary to present fairly the consolidated balance sheets, statements of income, comprehensive income, changes in stockholders’ equity and cash flows of Nicolet Bankshares, Inc. (the “Company” or “Nicolet”) and its subsidiaries, for the periods presented, and all such adjustments are of a normal recurring nature. All material intercompany transactions and balances have been eliminated. The results of operations for the interim periods are not necessarily indicative of the results to be expected for the entire year.

These interim consolidated financial statements have been prepared according to the rules and regulations of the Securities and Exchange Commission and, therefore, certain information and footnote disclosures normally presented in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) have been omitted or abbreviated. These consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and footnotes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018.

Critical Accounting Policies and Estimates

Preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying disclosures. These estimates are based on management’s best knowledge of current events and actions the Company may undertake in the future. Estimates are used in accounting for, among other items, the allowance for loan losses, valuation of loans in acquisition transactions, useful lives for depreciation and amortization, fair value of financial instruments, other-than-temporary impairment calculations, valuation of deferred tax assets, uncertain income tax positions and contingencies. Estimates that are particularly susceptible to significant change for the Company include the determination of the allowance for loan losses, the determination and assessment of deferred tax assets and liabilities, and the valuation of loans acquired in acquisition transactions; therefore, these are critical accounting policies. Factors that may cause sensitivity to the aforementioned estimates include but are not limited to: external market factors such as market interest rates and employment rates, changes to operating policies and procedures, changes in applicable banking or tax regulations, and changes to deferred tax estimates. Actual results may ultimately differ from estimates, although management does not generally believe such differences would materially affect the consolidated financial statements in any individual reporting period presented.

There have been no material changes or developments with respect to the assumptions or methodologies that the Company uses when applying what management believes are critical accounting policies and developing critical accounting estimates as disclosed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018.

Recent Accounting Developments Adopted

In August 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. ASU 2017-12 expands the activities that qualify for hedge accounting and simplifies the rules for reporting hedging transactions. The updated guidance is effective for interim and annual reporting periods beginning after December 15, 2018, with early adoption permitted. The Company adopted the updated guidance effective January 1, 2019 with no material impact on its consolidated financial statements, because the Company does not have any significant derivatives and does not currently apply hedge accounting to derivatives.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), with several subsequent updates. Topic 842 introduced a new accounting model for lessors and lessees. For lessees, almost all leases are now recognized on the balance sheet as a right-of-use ("ROU") asset and lease liability, unlike previous GAAP which required only capital leases to be recognized on the balance sheet. The accounting applied by lessors is largely unchanged from existing guidance. Topic 842 also requires additional disclosures concerning the amount, timing and uncertainty of cash flows arising from leases. The updated guidance is effective for annual reporting periods beginning after December 15, 2018, and provides a modified retrospective transition approach that allows lessees to recognize and measure leases on the balance sheet at the beginning of either the earliest period presented or as of the beginning of the period of adoption (the "effective date" method), with the option to elect certain practical expedients. Nicolet adopted the new guidance prospectively as of January 1, 2019, using the effective date method; thus, prior comparative periods have not been restated.

Upon adoption, Nicolet recognized an ROU asset and lease liability of approximately $5 million. There was no impact to its consolidated statements of income or cash flows compared to the prior lease accounting model. The ROU asset and lease liability are recorded in other assets and other liabilities, respectively, in the consolidated balance sheets. As part of the adoption, Nicolet elected the package of practical expedients permitted under the transition guidance of the new standard which allowed the carry forward of the historical lease classification. Nicolet also elected the practical expedient to group lease and non-lease components as a single lease component; thus, the Company's leases include both lease (e.g., fixed payments including rent, taxes, and insurance

8

costs) and non-lease components (e.g., common area or other maintenance costs). See Note 10 for the new disclosures required by Topic 842.

Reclassifications

Certain amounts in the 2018 consolidated financial statements have been reclassified to conform to the 2019 presentation.

Note 2 – Pending Acquisition

On June 26, 2019, Nicolet entered into a definitive merger agreement with Choice Bancorp, Inc. ("Choice" (OTC Pink "CBKW")) pursuant to which Choice will merge with and into Nicolet to create the largest community bank in the Oshkosh, Wisconsin marketplace. The acquisition will involve stock-for-stock consideration at a fixed exchange ratio, subject to cap and collar provisions provided for in the merger agreement. At June 30, 2019, Choice had total assets of $444 million, loans of $349 million, deposits of $312 million, and equity of $39 million. The merger is expected to close in the fourth quarter of 2019 and remains subject to customary closing conditions, including approval by Choice shareholders and regulatory approvals.

Note 3 – Earnings per Common Share

Basic earnings per common share are calculated by dividing net income available to common shareholders by the weighted average number of common shares outstanding during the period. Diluted earnings per common share are calculated by dividing net income available to common shareholders by the weighted average number of shares adjusted for the dilutive effect of common stock awards (outstanding stock options and unvested restricted stock), if any. Presented below are the calculations for basic and diluted earnings per common share.

	Three Months Ended June 30,				Six Months Ended June 30,
(In thousands, except per share data)	2019		2018		2019		2018
Net income attributable to Nicolet Bankshares, Inc.	$	18,549	$	9,737	$	28,816	$	19,314
Weighted average common shares outstanding	9,374		9,639		9,418		9,702
Effect of dilutive common stock awards	318		331		293		330
Diluted weighted average common shares outstanding	9,692		9,970		9,711		10,032
Basic earnings per common share*	$	1.98	$	1.01	$	3.06	$	1.99
Diluted earnings per common share*	$	1.91	$	0.98	$	2.97	$	1.93

*Cumulative quarterly per share performance may not equal annual per share totals due to the effects of the amount and timing of capital increases. When computing earnings per share for an interim period, the denominator is based on the weighted average shares outstanding during the interim period, and not on an annualized weighted average basis. Accordingly, the sum of the earnings per share data for the quarters will not necessarily equal the year to date earnings per share data.

For the three and six months endedJune 30, 2019, options to purchase less than 0.1 million shares are excluded from the calculation of diluted earnings per common share as the effect of their exercise would have been anti-dilutive. For the three and six months endedJune 30, 2018, options to purchase approximately 0.1 million shares are excluded from the calculation of diluted earnings per common share as the effect of their exercise would have been anti-dilutive.

Note 4 – Stock-Based Compensation

The Company may grant stock options and restricted stock under its stock-based compensation plans to certain officers, employees and directors. These plans are administered by a committee of the Board of Directors. In February 2019, with subsequent shareholder approval, the 2011 Long-Term Incentive Plan was amended to increase the shares reserved for potential stock-based awards from 1,500,000 shares to 3,000,000 shares. At June 30, 2019, approximately 1.6 million shares were available for grant under these stock-based compensation plans.

A Black-Scholes model is utilized to estimate the fair value of stock option grants, while the market price of the Company’s stock at the date of grant is used to estimate the fair value of restricted stock awards. The weighted average assumptions used in the Black-Scholes model for valuing stock option grants were as follows.

A summary of the Company’s stock option activity is summarized below.

Stock Options	Option Shares Outstanding		Weighted Average Exercise Price		Weighted Average Remaining Life (Years)	Aggregate Intrinsic Value (in thousands)
Outstanding - December 31, 2018	1,581,699		$	40.77
Granted	15,000		59.55
Exercise of stock options *	(137,443	)	23.15
Forfeited	(3,538	)	27.43
Outstanding - June 30, 2019	1,455,718		$	42.65	7.1	$	28,249
Exercisable - June 30, 2019	667,418		$	38.34	6.5	$	15,833

* The terms of the stock option agreements permit having a number of shares of stock withheld, the fair market value of which as of the date of exercise is sufficient to satisfy the exercise price and/or tax withholding requirements. For the six months endedJune 30, 2019, 64,681 such shares were surrendered to the Company.

Intrinsic value represents the amount by which the fair market value of the underlying stock exceeds the exercise price of the stock options. The intrinsic value of options exercised for the six months endedJune 30, 2019 and 2018 was approximately $5.0 million and $1.4 million, respectively.

A summary of the Company’s restricted stock activity is summarized below.

Restricted Stock	Weighted Average Grant Date Fair Value		Restricted Shares Outstanding
Outstanding - December 31, 2018	$	39.37	29,512
Granted	61.96		4,257
Vested *	44.79		(9,422	)
Forfeited	16.50		(408	)
Outstanding - June 30, 2019	$	41.64	23,939

* The terms of the restricted stock agreements permit the surrender of shares to the Company upon vesting in order to satisfy applicable tax withholding requirements at the minimum statutory withholding rate, and accordingly, 1,553 shares were surrendered during the six months endedJune 30, 2019.

The Company recognized approximately $2.2 million and $2.3 million of stock-based compensation expense (included in personnel on the consolidated statements of income) during the six months endedJune 30, 2019 and 2018, respectively, associated with its common stock awards granted to officers and employees. In addition, during the first half of 2019, the Company recognized approximately $0.3 million of director expense (included in other expense on the consolidated statements of income) for a total restricted stock grant of 4,257 shares with immediate vesting to directors. As of June 30, 2019, there was approximately $11.0 million of unrecognized compensation cost related to equity award grants. The cost is expected to be recognized over the remaining vesting period of approximately three years. The Company recognized a tax benefit of approximately $0.9 million and $0.2 million for the six months ended June 30, 2019 and 2018, respectively, for the tax impact of stock option exercises and vesting of restricted stock.

As of June 30, 2019, the Company does not consider its securities AFS with unrealized losses to be other-than-temporarily impaired, as the unrealized losses in each category have occurred as a result of changes in interest rates, market spreads and market conditions subsequent to purchase, not credit deterioration. The Company has the ability and intent to hold its securities to maturity. There were no other-than-temporary impairments charged to earnings during the six months endedJune 30, 2019 or 2018.

The amortized cost and fair value of securities AFS by contractual maturity are shown below. Expected maturities may differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties; as this is particularly inherent in mortgage-backed securities, these securities are not included in the maturity categories below.

Practically all of the Company’s loans, commitments, and letters of credit have been granted to customers in the Company’s market area. Although the Company has a diversified loan portfolio, the credit risk in the loan portfolio is largely influenced by general economic conditions and trends of the counties and markets in which the debtors operate, and the resulting impact on the operations of borrowers or on the value of underlying collateral, if any.

A description of the loan risk categories used by the Company follows.

Grades 1-4, Pass: Credits exhibit adequate cash flows, appropriate management and financial ratios within industry norms and/or are supported by sufficient collateral. Some credits in these rating categories may require a need for monitoring but elements of concern are not severe enough to warrant an elevated rating.

Grade 5, Watch: Credits with this rating are adequately secured and performing but are being monitored due to the presence of various short-term weaknesses which may include unexpected, short-term adverse financial performance, managerial problems, potential impact of a decline in the entire industry or local economy and delinquency issues. Loans to individuals or loans supported by guarantors with marginal net worth or collateral may be included in this rating category.

Grade 6, Special Mention: Credits with this rating have potential weaknesses that, without the Company’s attention and correction may result in deterioration of repayment prospects. These assets are considered Criticized Assets. Potential weaknesses may include adverse financial trends for the borrower or industry, repeated lack of compliance with Company requests, increasing debt to net worth, serious management conditions and decreasing cash flow.

Grade 7, Substandard: Assets with this rating are characterized by the distinct possibility the Company will sustain some loss if deficiencies are not corrected. All foreclosures, liquidations, and nonaccrual loans are considered to be categorized in this rating, regardless of collateral sufficiency.

Grade 8, Doubtful: Assets with this rating exhibit all the weaknesses as one rated Substandard with the added characteristic that such weaknesses make collection or liquidation in full highly questionable.

Grade 9, Loss: Assets in this category are considered uncollectible. Pursuing any recovery or salvage value is impractical but does not preclude partial recovery in the future.

The following tables present total loans by risk categories.

Note 7 – Goodwill and Other Intangibles and Mortgage Servicing Rights

Management periodically reviews the carrying value of its intangible assets to determine if any impairment has occurred, in which case an impairment charge would be recorded as an expense in the period of impairment, or whether changes in circumstances have occurred that would require a revision to the remaining useful life which would impact expense prospectively. In making such determination, management evaluates whether there are any adverse qualitative factors indicating that an impairment may exist, as well as the performance, on an undiscounted basis, of the underlying operations or assets which give rise to the intangible. The Company’s quarterly assessment indicated no impairment charge on goodwill, core deposit intangibles or customer list intangibles was required for the year ended December 31, 2018 or the six months endedJune 30, 2019. A summary of goodwill and other intangibles was as follows.

	Six Months Ended		Year Ended

Goodwill: Goodwill was $107.4 million at both June 30, 2019 and December 31, 2018.

Other intangible assets: Other intangible assets, consisting of core deposit intangibles and customer list intangibles, are amortized over their estimated finite lives.

Mortgage servicing rights: Mortgage servicing rights are amortized in proportion to and over the period of estimated net servicing income, and assessed for impairment at each reporting date, with the amortization recorded in mortgage income, net, in the consolidated statements of income. Mortgage servicing rights are carried at the lower of the initial capitalized amount, net of accumulated amortization, or estimated fair value, and are included in other assets in the consolidated balance sheets. A summary of the changes in the mortgage servicing rights asset was as follows.

Residential mortgage loans serviced for others	$	663,360		$	603,446
Net book value of MSR asset to loans serviced for others	0.64		%	0.62		%

The Company periodically evaluates its mortgage servicing rights asset for impairment. At each reporting date, impairment is assessed based on estimated fair value using estimated prepayment speeds of the underlying mortgage loans serviced and stratifications based on the risk characteristics of the underlying loans (predominantly loan type and note interest rate). No valuation allowance or impairment charge was recorded for the year ended December 31, 2018 or the six months endedJune 30, 2019. See Note 9 for additional information on the fair value of the MSR asset.

The following table shows the estimated future amortization expense for amortizing intangible assets and the MSR asset. The projections are based on existing asset balances, the current interest rate environment and prepayment speeds as of June 30, 2019. The actual amortization expense the Company recognizes in any given period may be significantly different depending upon acquisition or sale activities, changes in interest rates, prepayment speeds, market conditions, regulatory requirements and events or circumstances that indicate the carrying amount of an asset may not be recoverable.

Note 9 – Fair Value Measurements

Fair value represents the estimated price at which an orderly transaction to sell an asset or transfer a liability would take place between market participants at the measurement date under current market conditions (i.e., an exit price concept), and is a market-based measurement versus an entity-specific measurement.

The Company records and/or discloses financial instruments on a fair value basis. These financial assets and financial liabilities are measured at fair value in three levels, based on the markets in which the assets and liabilities are traded and the observability of the assumptions used to determine fair value. These levels are:

• Level 1 – quoted market prices in active markets for identical assets or liabilities that a company has the ability to access at the measurement date

• Level 2 – inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly

• Level 3 – significant unobservable inputs for the asset or liability, which are typically based on an entity’s own assumptions, as there is little, if any, related market activity

In instances where the fair value measurement is based on inputs from different levels, the level within which the entire fair value measurement will be categorized is based on the lowest level input that is significant to the fair value measurement in its entirety. This assessment of the significance of an input requires management judgment.

Recurring basis fair value measurements:

The following table presents the balances of assets and liabilities measured at fair value on a recurring basis for the periods presented.

The following is a description of the valuation methodologies used by the Company for the securities AFS and equity securities measured at fair value on a recurring basis, noted in the tables above. Where quoted market prices on securities exchanges are available, the investments are classified as Level 1. Level 1 investments primarily include exchange-traded equity securities. If quoted market prices are not available, fair value is generally determined using prices obtained from independent pricing vendors who use pricing models (with typical inputs including benchmark yields, reported trades for similar securities, issuer spreads or relationship to other benchmark quoted securities), or discounted cash flows, and are classified as Level 2. Examples of these investments include U.S. government agency securities, mortgage-backed securities, obligations of state, county and municipals, and certain corporate debt securities. Finally, in certain cases where there is limited activity or less transparency around inputs to the estimated fair value, investments are classified within Level 3 of the hierarchy. Examples of these include private municipal bonds and corporate debt securities, which include trust preferred security investments. At June 30, 2019 and December 31, 2018, it was determined that carrying value was the best approximation of fair value for these Level 3 securities, based primarily on the internal analysis on these securities.

The following table presents the changes in the Level 3 securities AFS measured at fair value on a recurring basis.

The following is a description of the valuation methodologies used by the Company for the items noted in the table above. For individually evaluated impaired loans, the amount of impairment is based upon the present value of expected future cash flows discounted at the loan’s effective interest rate, the estimated fair value of the underlying collateral for collateral-dependent loans, or the estimated liquidity of the note. For OREO, the fair value is based upon the estimated fair value of the underlying collateral adjusted for the expected costs to sell. To estimate the fair value of the MSR asset, the underlying serviced loan pools are stratified by interest rate tranche and term of the loan, and a valuation model is used to calculate the present value of the expected future cash flows for each stratum. The valuation model incorporates assumptions that market participants would use in estimating future net servicing income, such as costs to service, a discount rate, ancillary income, default rates and losses, and prepayment speeds. Although some of these assumptions are based on observable market data, other assumptions are based on unobservable estimates of what market participants would use to measure fair value.

The carrying value of certain assets and liabilities such as cash and cash equivalents, BOLI, and nonmaturing deposits, approximate their estimated fair value. For those financial instruments not previously disclosed, the following is a description of the valuation methodologies used.

Certificates of deposits in other banks: Fair values are estimated using discounted cash flow analysis based on current interest rates being offered by instruments with similar terms and represents a Level 2 measurement.

Other investments: The valuation methodologies utilized for exchange-traded equity securities are discussed under “Recurring basis fair value measurements” above. The carrying amount of Federal Reserve Bank and FHLB stock is a reasonably accepted fair value estimate given their restricted nature. Fair value is the redeemable (carrying) value based on the redemption provisions of the instruments which is considered a Level 2 measurement. The carrying amount of the remaining other investments (particularly common stocks of companies or other banks that are not publicly traded) approximates their fair value, determined primarily by

24

analysis of company financial statements and recent capital issuances of the respective companies or banks, if any, and represents a Level 3 measurement.

Loans held for sale: The fair value estimation process for the loans held for sale portfolio is segregated by loan type. The estimated fair value was based on what secondary markets are currently offering for portfolios with similar characteristics and represents a Level 2 measurement.

Loans, net: For variable-rate loans that reprice frequently and with no significant change in credit risk or other optionality, fair values are based on carrying values. Fair values for all other loans are estimated by discounting contractual cash flows using estimated market discount rates, which reflect the credit and interest rate risk inherent in the loan. Collateral-dependent impaired loans are included in loans, net. The fair value of loans is considered to be a Level 3 measurement due to internally developed discounted cash flow measurements.

Deposits: The fair value of deposits with no stated maturity (such as demand deposits, savings, interest and noninterest checking, and money market accounts) is, by definition, equal to the amount payable on demand at the reporting date. Fair values for fixed-rate certificates of deposit are estimated using a discounted cash flow calculation that applies interest rates currently being offered in the market place on certificates of similar remaining maturities. Use of internal discounted cash flows provides a Level 3 fair value measurement.

Long-term borrowings: The fair value of the FHLB advances is obtained from the FHLB which uses a discounted cash flow analysis based on current market rates of similar maturity debt securities and represents a Level 2 measurement. The fair values of the junior subordinated debentures and subordinated notes utilize a discounted cash flow analysis based on an estimate of current interest rates being offered by instruments with similar terms and credit quality. Since the market for these instruments is limited, the internal evaluation represents a Level 3 measurement.

Lending-related commitments and derivative financial instruments: At June 30, 2019 and December 31, 2018, the estimated fair value of letters of credit, interest rate lock commitments on residential mortgage loans, outstanding mandatory commitments to sell residential mortgage loans into the secondary market, and mirror interest rate swap agreements were not significant.

Limitations: Fair value estimates are made at a specific point in time, based on relevant market information and information about the financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale at one time the Company’s entire holdings of a particular financial instrument. Fair value estimates may not be realizable in an immediate settlement of the instrument. In some instances, there are no quoted market prices for the Company’s various financial instruments, in which case fair values may be based on estimates using present value or other valuation techniques, or based on judgments regarding future expected loss experience, current economic conditions, risk characteristics of the financial instruments, or other factors. Those techniques are significantly affected by the assumptions used, including the discount rate and estimate of future cash flows. Subsequent changes in assumptions could significantly affect the estimates.

Note 10 – Operating Leases

As of January 1, 2019, the Company adopted ASU 2016-02 (Topic 842) on a prospective basis using the effective date method. The adoption of the new standard did not have a material impact on Nicolet's financial statements; however, additional disclosures have been added in accordance with the ASU. See Note 1 for additional information on this new accounting standard.

The operating lease ROU asset represents the right to use an underlying asset during the lease term, while the operating lease liability represents the obligation to make lease payments arising from the lease. The ROU asset and lease liability are recognized at lease commencement based on the present value of the remaining lease payments, considering a discount rate that represents Nicolet's incremental borrowing rate. Operating lease expense is recognized on a straight-line basis over the lease term and is recognized in occupancy, equipment, and office on the consolidated statements of income.

Nicolet leases space under non-cancelable operating lease agreements for certain bank and nonbank branch facilities with remaining lease terms of 2 to 7 years. Certain lease arrangements contain extension options which typically range from 5 to 10 years at the then fair market rental rates. The lease asset and liability considers renewal options when they are reasonably certain of being exercised.

Net income was $28.8 million for the six months endedJune 30, 2019, an increase of $9.5 million or 49% over $19.3 million for the six months endedJune 30, 2018. Earnings per diluted common share was $2.97 for the first six months of 2019, 54% higher than $1.93 for the comparable 2018 period.

• During second quarter 2019, Nicolet sold approximately 80% of its equity investment in UFS, LLC, a data processing and e-banking entity, and recognized a $7.4 million after-tax gain (included in noninterest income under asset gains) and recorded $2.75 million ($2.0 million after-tax) in personnel expense for retirement-related compensation declared. Consistent with our philosophy of aligning outcomes to customers, shareholders, and employees, the board approved these retirement-related compensation actions to benefit all employees following the recognition of the gain on the equity investment sale. Combined, net of taxes, these actions impacted net income favorably by $5.4 million and diluted earnings per common share by $0.55.

• Net interest income was $56.4 million for the first six months of 2019, up $3.7 million or 7% over first half 2018. Interest income grew $6.4 million (despite $1.0 million lower aggregate discount income on purchased loans), aided by a higher mix of average interest-earning assets in loans and the elevated rate environment on new, renewed and variable rate loans. Interest expense increased $2.7 million primarily due to rising rates. Net interest margin was 4.16% for the six months endedJune 30, 2019, compared to 3.98% for the six months endedJune 30, 2018. For additional information regarding net interest income, see “Income Statement Analysis — Net Interest Income.”

• Noninterest income was $27.7 million for first half 2019, up $8.7 million or 46% over the comparable 2018 period, mostly due to the $7.4 million gain on the equity investment sale noted above. For additional information regarding noninterest income, see “Income Statement Analysis — Noninterest Income.”

• Noninterest expense was $48.5 million, $3.4 million or 8% higher than first half 2018, mostly due to the retirement-related compensation actions in second quarter 2019 noted above. Personnel costs increased $2.7 million, and non-personnel expenses combined increased $0.7 million or 3% over first half 2018. For additional information regarding noninterest expense, see “Income Statement Analysis — Noninterest Expense.”

• Asset quality remains sound. Nonperforming assets were $8.0 million, representing 0.26% of total assets at June 30, 2019, up modestly from 0.19% at December 31, 2018 and down favorably from 0.41% at June 30, 2018. For additional information regarding nonperforming assets, see “Balance Sheet Analysis – Nonperforming Assets.”

• At June 30, 2019, assets were $3.1 billion, a decrease of $42 million (1%) from December 31, 2018 (largely due to a $95 million decrease in cash and cash equivalents exceeding a $37 million increase in loans) and an increase of $133 million (5%) from June 30, 2018 (mostly due to a $51 million increase in cash and cash equivalents and $75 million increase in loans).

• At June 30, 2019, loans were $2.2 billion, 2% higher than December 31, 2018 and 4% higher than June 30, 2018. On average, loans grew $68 million or 3% over first half 2018. For additional information regarding loans, see “Balance Sheet Analysis — Loans.”

• Total deposits were $2.5 billion at June 30, 2019, a decrease of 3% from December 31, 2018 and 3% higher than June 30, 2018. Average deposits were $25 million or 1% higher than first half 2018 (which included a $0.1 billion impact of carrying a $0.3 billion short-term transaction deposit of a large commercial customer from late March to mid-June 2018). For additional information regarding deposits, see “Balance Sheet Analysis – Deposits.”

INCOME STATEMENT ANALYSIS

Net Interest Income

Tax-equivalent net interest income is a non-GAAP measure, but is a preferred industry measurement of net interest income (and its use in calculating a net interest margin) as it enhances the comparability of net interest income arising from taxable and tax-exempt sources. The tax-equivalent adjustments bring tax-exempt interest to a level that would yield the same after-tax income by applying the effective Federal corporate tax rates to the underlying assets. Tables 2 and 3 present information to facilitate the review and discussion of selected average balance sheet items, tax-equivalent net interest income, interest rate spread and net interest margin.

(1) The change in interest due to both rate and volume has been allocated in proportion to the relationship of dollar amounts of change in each.

(2) The yield on tax-exempt loans and tax-exempt investment securities is computed on a tax-equivalent basis using a federal tax rate of 21% and adjusted for the disallowance of interest expense.

The Federal Reserve raised short-term interest rates by 25 bps in eight moves from fourth quarter 2016 through fourth quarter 2018 (up 200 bps total) to 2.50% at December 31, 2018, with no short-term moves in 2019 through June 30. The noted increases impacted the rate earned on short-term assets and pressured the cost of shorter-term borrowings, but did not consistently cause a corresponding increase on rates further out on the curve. Hence, 2018 was characterized by a flattening yield curve, while the first six months of 2019 has had periods of an inverted yield curve.

Tax-equivalent net interest income was $57.0 million for the first six months of 2019, comprised of net interest income of $56.4 million ($3.7 million or 7% higher than first half 2018, overcoming $1.0 million lower aggregate discount accretion on purchased loans), and a $0.5 million tax-equivalent adjustment (relatively unchanged between the periods). The $3.7 million increase in tax-equivalent net interest income was due to favorable volumes (which added $2.1 million, with $2.0 million from higher loan volumes) and favorable rates (which added $1.6 million). The net $1.6 million increase from rates was from interest-earning asset rate changes in the higher interest rate environment (improving net interest income by $4.2 million, of which $3.6 million was from loans, inclusive of the lower aggregate discount accretion), exceeding the rising cost of funds (which cost $2.6 million more, led by interest-bearing deposits and most notably time deposits).

Between the comparable six-month periods, the interest rate spread increased 5 bps due to an increase in the interest-earning asset yield (up 37 bps to 5.00%, aided by an improved mix of assets in higher-yielding loans), exceeding a rise in the cost of funds (up 32 bps to 1.19%). The contribution from net free funds increased 13 bps, due mostly to the increase in average noninterest-bearing demand deposits (up 19%) and their increased value in the higher rate environment. As a result, the tax-equivalent net interest margin was 4.16% for first half 2019, up 18 bps compared to 3.98% for the comparable 2018 period.

Average interest-earning assets were $2.7 billion for the first six months of 2019, $55 million or 2% higher than the comparable 2018 period. Between the six-month periods, average loans increased $68 million or 3%, while all other interest-earning assets declined $13 million (mainly in lower earning cash, as total investment securities were relatively unchanged). The 2019 mix of average interest-earning assets was 80% loans, 15% investments, and 5% other interest-earning assets (mostly cash), compared to 79%, 15% and 6%, respectively, for first half 2018.

32

Tax-equivalent interest income was $68.3 million for first half 2019, up $6.3 million or 10% over first half 2018, while the related interest-earning asset yield was 5.00%, up 37 bps over first half 2018. Interest income on loans increased $5.5 million or 10% over first half 2018, despite $1.0 million lower aggregate discount accretion income between the periods (predominantly attributable to aging discounts on purchased loans). The 2019 loan yield was 5.59%, up 34 bps over first half 2018 (which, if excluding the aggregate discount accretion income from both six-month periods, would have increased 44 bps), as improved yields on new, renewed and variable rate loans in the higher rate environment more than offset the lower aggregate discount income. Between the comparable six-month periods, interest income on non-loan earning assets combined increased $0.8 million or 13%, while the related yield increased 37 bps to 2.62%, due mostly to the higher rate on cash levels, as well as higher yields on new investments added in the higher rate environment.

Average interest-bearing liabilities were $1.9 billion, a decrease of $86.0 million or 4% compared to first half 2018, primarily due to an $85.2 million or 4% decrease in interest-bearing deposits (with organic growth partially offsetting the $0.1 billion impact on first half 2018 of carrying a $0.3 billion short-term transaction deposit of a large commercial customer from late March to mid-June 2018). With core deposit growth (especially in core time deposits, responding to more favorable rate offerings between the years), brokered deposits have continued to decline. The mix of average interest-bearing liabilities was 92% core deposits, 4% brokered deposits and 4% other funding, compared to 90%, 6% and 4%, respectively, for first half 2018.

Interest expense was $11.3 million for first half 2019, up $2.7 million over first half 2018, and the related cost of funds increased 32 bps to 1.19%, driven predominantly by the cost, mix and volume of deposits. Interest expense on deposits increased $2.6 million from first half 2018 and the average cost of interest-bearing deposits increased 31 bps to 1.04%, influenced by increases in select deposit rates from general rate pressures of the higher rate environment and the larger proportion of core time deposits. The 2019 cost of savings, interest-bearing demand and money market accounts increased over first half 2018 by 13 bps, 25 bps and 13 bps, respectively, as product rate changes lagged the incremental rise in the rate environment, and time deposits cost 74 bps more between the six-month periods commensurate with paying more for a customer's commitment of term in the higher rate environment.

Asset quality trends remained strong. The provision for loan losses was $0.5 million for the six months endedJune 30, 2019, compared to $1.0 million for the six months endedJune 30, 2018. The ALLL was $13.6 million (0.62% of loans) at June 30, 2019, compared to $13.2 million (0.61% of loans) at December 31, 2018 and $12.9 million (0.60% of loans) at June 30, 2018.

The provision for loan losses is predominantly a function of Nicolet’s methodology and judgment as to qualitative and quantitative factors used to determine the appropriateness of the ALLL. The appropriateness of the ALLL is affected by changes in the size and character of the loan portfolio, changes in levels of impaired and other nonperforming loans, historical losses and delinquencies in each portfolio segment, the risk inherent in specific loans, concentrations of loans to specific borrowers or industries, existing and future economic conditions, the fair value of underlying collateral, and other factors which could affect potential credit losses.

Noninterest income was $27.7 million for first half 2019, compared to $19.1 million for first half 2018, an increase of $8.7 million or 46%, mostly due to the $7.4 million gain on the equity investment sale noted previously. Noninterest income excluding net asset gains grew $2.1 million or 12% between the comparable six-month periods, with most categories up year over year.

Trust services fee income and brokerage fee income combined were up $0.2 million or 3% with some Trust accounts being transferred into the Brokerage accounts.

Mortgage income represents net gains received from the sale of residential real estate loans into the secondary market, capitalized mortgage servicing rights (“MSRs”), servicing fees, fair value marks on the mortgage interest rate lock commitments and forward commitments, offsetting MSR amortization, MSR valuation changes, if any, and to a smaller degree some related income. Net mortgage income increased $0.7 million or 25% between the comparable six-month periods, predominantly from higher MSR gains (reflective of changes in MSR capitalization assumptions in mid-2018), higher gains on sale, and increased net servicing fees on the growing portfolio of mortgage loans serviced for others, partially offset by unfavorable changes in the fair value of the mortgage interest rate lock and forward commitments.

Service charges on deposits accounts were minimally changed at $2.4 million for both six-month periods. The change in the 2019 deposit base had minimal impact on service charges since most of the deposit growth in 2019 occurred in time deposits and the increase to the earnings credit rate in mid-2018 mostly offset the growth in transaction deposits.

Card interchange income grew $0.5 million or 18% due to higher volume and activity.

BOLI income increased $0.4 million, fully attributable to a BOLI death benefit received in second quarter 2019.

Other income increased $0.3 million, mostly attributable to the fee earned on a customer loan interest rate swap in second quarter 2019.

The $7.7 million net asset gains in first half 2019 were comprised primarily of the $7.4 million gain on the equity investment sale and $0.6 million of favorable fair value marks on equity securities, partially offset by losses of $0.1 million on the disposal of fixed assets, a $0.1 million write-down on an OREO property, and a $0.1 million write-down on an other investment. The $7.4 million equity investment gain was related to Nicolet's sale of approximately 80% of its equity interest in UFS, LLC, a data processing and e-banking entity. The $1.2 million net asset gains in first half 2018 were primarily attributable to $0.6 million of net gains on the sale of fixed assets, a $0.3 million fair value mark on equity securities, and a $0.2 million gain on the sale of equity securities.

Noninterest expense was $48.5 million, an increase of $3.4 million or 8% over first half 2018. Personnel costs increased $2.7 million, and non-personnel expenses combined increased $0.7 million or 3% over the first half of 2018.

Personnel expense was $27.9 million for the first six months of 2019, an increase of $2.7 million or 11% over the comparable period in 2018. As previously noted, the increase in personnel expense was largely driven by $2.75 million of retirement-related compensation actions in second quarter 2019, including a discretionary profit sharing contribution of $1.05 million to the 401k plan and a $1.7 million contribution to the nonqualified deferred compensation plan. Consistent with our philosophy of aligning outcomes to customers, shareholders, and employees, the board approved these retirement-related compensation actions to benefit

34

all employees following the recognition of the gain on the equity investment sale. Personnel expense was also impacted by merit increases between the periods (though on a minimally changed workforce, with average full-time equivalents up less than 1%), lower equity and cash incentives (mostly timing in nature), and lower health and other benefit costs.

Occupancy, equipment and office expense was $7.5 million for first half 2019, up $0.3 million or 4% compared to first half 2018, with 2019 including higher expense for software and technology solutions to drive operational efficiency and product or service enhancements, and both periods including approximately $0.2 million of accelerated depreciation for branch facility upgrades.

Business development and marketing expense was $2.9 million, up $0.1 million or 2%, between the comparable six-month periods, largely due to the timing and extent of donations, marketing campaigns, promotions, and media.

Intangibles amortization decreased $0.3 million between the first half periods from declining amortization on the aging intangibles of previous acquisitions. Other expense was $3.5 million, up $0.6 million or 21% between the comparable six-month periods, due primarily to a $0.3 million fraud contingency loss recognized in first quarter 2019 and $0.3 million for the annual equity retainer granted to directors in second quarter 2019 (versus granted in third quarter last year).

Income Taxes

Income tax expense was $6.2 million (effective tax rate of 17.6%) for first half 2019, compared to $6.2 million (effective tax rate of 24.0%) for the comparable period of 2018. The lower effective tax rate was due to the favorable tax treatment of the equity investment sale, BOLI death benefit, and the tax benefit on stock-based compensation.

Income Statement Analysis – Three Months Ended June 30, 2019 versus Three Months Ended June 30, 2018

Net income was $18.5 million for the three months ended June 30, 2019, an increase of $8.8 million or 91% over $9.7 million for the three months ended June 30, 2018. Earnings per diluted common share was $1.91 for second quarter 2019, 95% higher than $0.98 for second quarter 2018. Net income in second quarter 2019 included $5.4 million from two nonrecurring items, a $7.4 million after-tax gain from the equity investment sale previously noted (recorded in net asset gains) and $2.75 million ($2.0 million after tax) in personnel expense for retirement-related compensation actions.

Tax-equivalent net interest income was $29.2 million for second quarter 2019, comprised of net interest income of $28.9 million ($3.1 million or 12% over second quarter 2018, driven mostly by net positive rate variances, including $0.6 million higher aggregate discount accretion on purchased loans), and a tax-equivalent adjustment of $0.3 million (unchanged from second quarter 2018). Tax-equivalent interest income increased $4.0 million between the second quarter periods, with $3.6 million from improved yields across all interest-earning assets though led by loans (with a 65 bps increase in the interest-earning asset yield) and $0.4 million from stronger volumes (led by average loans which grew to represent 81% of interest-earning assets versus 77% for second quarter 2018). Interest expense increased $0.9 million over second quarter 2018, with $1.0 million from rising rates (with a 28 bps increase in the cost of funds) and the remainder from higher volumes, both led by deposits and deposit mix. For additional information regarding average balances and net interest income, see “Income Statement Analysis — Net Interest Income.”

Second quarter 2019 earning asset yield, cost of funds, and net interest margin were 5.11%, 1.19% and 4.28%, respectively, compared to 4.46%, 0.91% and 3.77%, respectively, for second quarter 2018. Of note, a $0.3 billion short-term transaction deposit of a long-standing customer was carried from late March to mid-June 2018, increasing second quarter 2018 average deposits and interest-bearing cash each by approximately $0.2 billion. The inclusion of the large deposit was a positive contributor to second quarter 2018 net interest income, though at a very low net spread, which lowered that quarter's reported earning asset yield and net interest margin by approximately 20 bps each and lowered the reported cost of funds by approximately 2 bps. For additional information regarding net interest income, see “Income Statement Analysis — Net Interest Income.”

Asset quality remained exceptional. For second quarter 2019, provision for loan losses was $0.3 million (covering $0.1 million of net charge-offs), compared to provision for loan losses of $0.5 million (covering $0.4 million of net charge-offs) for second quarter 2018.

Noninterest income was $18.6 million for second quarter 2019, an increase of $8.3 million or 81% over second quarter 2018. Excluding net asset gains, noninterest income increased $1.7 million or 19%, largely due to mortgage income (up $0.5 million or 35% on higher sales volume and a larger servicing portfolio), trust services fee income and brokerage fee income combined (up $0.2 million or 5%, with some Trust accounts being transferred into Brokerage), card interchange income (up $0.3 million or 22% on higher volume and activity), and BOLI income (up $0.4 million from a death benefit). Net asset gains of $7.6 million for second quarter 2019 were largely attributable to the $7.4 million gain on the equity investment sale noted previously. Net asset gains of $1.0 million for second quarter 2018 were primarily attributable to $0.4 million of net gains on the sale of fixed assets, a $0.4 million fair value mark on equity securities, and a $0.2 million gain on the sale of equity securities. For additional information regarding noninterest income, see “Income Statement Analysis — Noninterest Income.”

Noninterest expense was $25.7 million for second quarter 2019, an increase of $3.3 million or 15% over second quarter 2018. Personnel expense increased $2.7 million or 21% from second quarter 2018, fully attributable to the large retirement-related compensation noted previously. Personnel expense was also impacted by merit increases between the periods (though on a

35

minimally changed workforce, with average full-time equivalents up less than 1%), lower equity and cash incentives (mostly timing in nature), and minimally changed health and other benefit costs. Non-personnel expenses combined increased $0.6 million or 6%, largely due to occupancy, equipment, and office (up $0.3 million or 9%, attributable to accelerated depreciation for branch facility upgrades) and other expense (up $0.4 million or 26%, mainly from the $0.3 million annual equity retainer granted to directors in second quarter versus third quarter last year). For additional information regarding noninterest expense, see “Income Statement Analysis — Noninterest Expense.”

Income tax expense for second quarter 2019 was $2.8 million, with an effective tax rate of 13.2%, compared to income tax expense of $3.3 million and an effective tax rate of 24.9% for second quarter 2018. The lower income tax expense and effective tax rate was due to the favorable tax treatment of the equity investment sale, BOLI death benefit, and the tax benefit on stock-based compensation.

BALANCE SHEET ANALYSIS

At June 30, 2019, assets were $3.1 billion, a decrease of $42 million or 1% from December 31, 2018, while deposits were $2.5 billion, a decrease of $78 million or 3% over the same period, with both reflecting the usual cyclical decline. Loans grew $37 million or 2% to $2.2 billion at June 30, 2019. Total stockholders’ equity was $411 million, an increase of $25 million from December 31, 2018, with earnings and net fair value investment changes partially offset by stock repurchases.

Compared to June 30, 2018, assets were $3.1 billion, up $133 million or 5%, and deposits were $2.5 billion, an increase of $81 million or 3%, largely due to growth in time deposits. Loans increased $75 million or 4% from June 30, 2018. Compared to June 30, 2018, stockholders’ equity increased $41 million, primarily due to net income, stock issuances, and net fair value investment changes partially offset by stock repurchases over the year.

Loans

Nicolet services a diverse customer base throughout northeastern and central Wisconsin and in Menominee, Michigan. The Company concentrates on originating loans in its local markets and assisting its current loan customers. The loan portfolio is widely diversified by types of borrowers, industry groups, and market areas. Significant loan concentrations are considered to exist for a financial institution when there are amounts loaned to multiple numbers of borrowers engaged in similar activities that would cause them to be similarly impacted by economic or other conditions. At June 30, 2019, no significant industry concentrations existed in Nicolet’s portfolio in excess of 10% of total loans. Nicolet has also developed guidelines to manage its exposure to various types of concentration risks. See also Note 6, “Loans, Allowance for Loan Losses, and Credit Quality” of the Notes to Unaudited Consolidated Financial Statements under Part I, Item 1, for additional disclosures on loans.

An active credit risk management process is used to ensure that sound and consistent credit decisions are made. The credit management process is regularly reviewed and the process has been modified over the past several years to further strengthen the controls. Factors that are important to managing overall credit quality are sound loan underwriting and administration, systematic monitoring of existing loans and commitments, effective loan review on an ongoing basis, early problem loan identification and remedial action to minimize losses, an appropriate ALLL, and sound nonaccrual and charge-off policies.

Broadly, the loan portfolio at June 30, 2019, was 76% commercial-based and 24% retail-based. Commercial-based loans are considered to have more inherent risk of default than retail-based loans, in part because of the broader list of factors that could impact a commercial borrower negatively. In addition, the commercial balance per borrower is typically larger than that for retail-based loans, implying higher potential losses on an individual customer basis. Credit risk on commercial-based loans is largely influenced by general economic conditions and the resulting impact on a borrower’s operations or on the value of underlying collateral, if any.

Commercial-based loans of $1.7 billion increased $35 million or 2% since December 31, 2018, primarily due to growth in commercial and industrial loans. Commercial and industrial loans continue to be the largest segment of Nicolet’s portfolio and represented 34% of the total portfolio at June 30, 2019.

Residential real estate loans were relatively unchanged from year-end 2018, and represented 23% of total loans at June 30, 2019. Residential first mortgage loans include conventional first-lien home mortgages, while residential junior mortgage real estate loans consist mainly of home equity lines and term loans secured by junior mortgage liens. As part of its management of originating residential mortgage loans, the vast majority of Nicolet’s long-term, fixed-rate residential real estate mortgage loans are sold in the secondary market with or without retaining the servicing rights. Nicolet's mortgage loans are typically of high quality and have historically had low net charge-off rates.

Retail and other loans (up $2 million from year-end 2018) represented approximately 1% of the total loan portfolio, and include predominantly short-term and other personal installment loans not secured by real estate.

Allowance for Loan Losses

In addition to the discussion that follows, see also Note 6, “Loans, Allowance for Loan Losses, and Credit Quality,” in the Notes to Unaudited Consolidated Financial Statements under Part I, Item 1, for additional disclosures on the allowance for loan losses.

Credit risks within the loan portfolio are inherently different for each loan type as summarized under “BALANCE SHEET ANALYSIS — Loans.” A detailed discussion of the loan portfolio credit risk can be found in the "Loans" section in Management's Discussion and Analysis of Financial Condition and Results of Operations included in the Company's 2018 Annual Report on Form 10-K. There have been no material changes in the credit risk of the Company's loan portfolio since December 31, 2018. Credit risk is controlled and monitored through the use of lending standards, a thorough review of potential borrowers, and ongoing review of loan payment performance. Active asset quality administration, including early problem loan identification and timely resolution of problems, aids in the management of credit risk and minimization of loan losses.

The level of the ALLL represents management’s estimate of an amount of reserves that provides for estimated probable credit losses in the loan portfolio at the balance sheet date. To assess the appropriateness of the ALLL, an allocation methodology is applied by Nicolet which focuses on evaluation of qualitative and environmental factors, including but not limited to: (i) evaluation of facts and issues related to specific loans; (ii) management’s ongoing review and grading of the loan portfolio; (iii) consideration of historical loan loss and delinquency experience on each portfolio segment; (iv) trends in past due and nonperforming loans; (v)

37

the risk characteristics of the various loan segments; (vi) changes in the size and character of the loan portfolio; (vii) concentrations of loans to specific borrowers or industries; (viii) existing economic conditions; (ix) the fair value of underlying collateral; and (x) other qualitative and quantitative factors which could affect potential credit losses. Assessing these numerous factors involves significant judgment; therefore, management considers the ALLL a critical accounting policy.

Management allocates the ALLL by pools of risk within each loan portfolio segment. The allocation methodology consists of the following components. First, a specific reserve for the estimated shortfall is established for all loans determined to be impaired. The specific reserve in the ALLL is equal to the aggregate collateral or discounted cash flow shortfall calculated from the impairment analysis. For determining the appropriateness of the ALLL, management defines impaired loans as nonaccrual credit relationships over $250,000, all loans determined to be troubled debt restructurings (“restructured loans”), plus additional loans with impairment risk characteristics. Second, management allocates the ALLL with historical loss rates by loan segment. The loss factors applied are periodically re-evaluated and adjusted to reflect changes in historical loss levels on an annual basis. The look-back period on which the average historical loss rates are determined is a rolling 20-quarter (5 year) average. Lastly, management allocates ALLL to the remaining loan portfolio using the qualitative factors mentioned above. Consideration is given to those current qualitative or environmental factors that are likely to cause estimated credit losses as of the evaluation date to differ from the historical loss experience of each loan segment. Management conducts its allocation methodology on both the originated loans and on the acquired loans separately to account for differences, such as different loss histories and qualitative factors, between the two loan portfolios.

At June 30, 2019, the ALLL was $13.6 million compared to $13.2 million at December 31, 2018. The components of the ALLL are detailed further in Table 7 below. Annualized net charge-offs as a percent of average loans were 0.01% for first half 2019, compared to 0.08% for first half 2018 and 0.05% for the entire 2018 year.

The ratio of the ALLL as a percentage of period-end loans was 0.62% at June 30, 2019, compared to 0.61% and 0.60% for December 31, 2018 and June 30, 2018, respectively. The ALLL to loans ratio is impacted by the accounting treatment of Nicolet’s bank acquisitions, which combined at their acquisition dates (from 2013 to 2017) added no ALLL to the numerator and $1.3 billion of loans into the denominator. Remaining outstanding acquired loans were $625 million (28% of total loans) and $681 million (31% of total loans) at June 30, 2019 and December 31, 2018, respectively. At June 30, 2019, the $13.6 million ALLL was comprised of $1.6 million for acquired loans (0.26% of acquired loans) and $11.9 million for originated loans (0.76% of originated loans). In comparison, at December 31, 2018, the $13.2 million ALLL was comprised of $1.7 million for acquired loans (0.25% of acquired loans) and $11.4 million for originated loans (0.77% of originated loans).

Nonperforming Assets

As part of its overall credit risk management process, management is committed to an aggressive problem loan identification philosophy. This philosophy has been implemented through the ongoing monitoring and review of all pools of risk in the loan portfolio to ensure that problem loans are identified early and the risk of loss is minimized. See also Note 6, “Loans, Allowance for Loan Losses, and Credit Quality” of the Notes to Unaudited Consolidated Financial Statements under Part I, Item 1, for additional disclosures on credit quality.

Nonperforming loans are considered one indicator of potential future loan losses. Nonperforming loans are defined as nonaccrual loans, including those defined as impaired under current accounting standards, and loans 90 days or more past due but still accruing interest. Loans are generally placed on nonaccrual status when contractually past due 90 days or more as to interest or principal payments. Additionally, whenever management becomes aware of facts or circumstances that may adversely impact the collectability of principal or interest on loans, it is management’s practice to place such loans on nonaccrual status immediately. Nonaccrual loans were $7.7 million (consisting of $4.3 million originated loans and $3.4 million acquired loans) at June 30, 2019 compared to $5.5 million at December 31, 2018 (consisting of $1.4 million originated loans and $4.1 million acquired loans). Nonperforming assets (which include nonperforming loans and other real estate owned “OREO”) were $8.0 million at June 30, 2019 compared to $5.9 million at December 31, 2018. OREO was $0.3 million at June 30, 2019 and $0.4 million at December 31, 2018. Nonperforming assets as a percent of total assets were 0.26% at June 30, 2019 compared to 0.19% at December 31, 2018.

The level of potential problem loans is another predominant factor in determining the relative level of risk in the loan portfolio and in determining the appropriate level of the ALLL. Potential problem loans are generally defined by management to include loans rated as Substandard by management but that are in performing status; however, there are circumstances present which might adversely affect the ability of the borrower to comply with present repayment terms. The decision of management to include performing loans in potential problem loans does not necessarily mean that Nicolet expects losses to occur, but that management recognizes a higher degree of risk associated with these loans. The loans that have been reported as potential problem loans are predominantly commercial-based loans covering a diverse range of businesses and real estate property types. Potential problem loans were $26.5 million (1.2% of loans) and $21.9 million (1.0% of loans) at June 30, 2019 and December 31, 2018, respectively. Potential problem loans require a heightened management review of the pace at which a credit may deteriorate, the duration of asset quality stress, and uncertainty around the magnitude and scope of economic stress that may be felt by Nicolet’s customers and on underlying real estate values.

Deposits

Deposits represent Nicolet’s largest source of funds. The deposit composition is presented in Table 9 below.

Total deposits were $2.5 billion at June 30, 2019, $77 million or 3% lower than December 31, 2018, reflecting the usual cyclical decline. Notably, the decrease in total deposits since year-end 2018 was largely due to money market and interest-bearing demand (down $109 million or 9%), partially offset by growth in savings and time accounts.

Compared to June 30, 2018, total deposits were up $81 million or 3%. Notably, the increase in total deposits since June 30, 2018 was largely due to noninterest-bearing demand accounts (up $122 million or 20%) as well as growth in savings and time accounts, partially offset by reductions in money market and interest-bearing demand (down $115 million or 10%).

Lending-Related Commitments

As of June 30, 2019 and December 31, 2018, Nicolet had the following off-balance sheet lending-related commitments.

Table 10: Commitments

(in thousands)	June 30, 2019		December 31, 2018
Commitments to extend credit	$	720,685	$	721,098
Financial standby letters of credit	11,399		8,571
Performance standby letters of credit	9,164		7,094

Interest rate lock commitments to originate residential mortgage loans held for sale (included above in commitments to extend credit) and forward commitments to sell residential mortgage loans held for sale are considered derivative instruments and represented $80.3 million and $15.2 million, respectively, at June 30, 2019. In comparison, interest rate lock commitments to originate residential mortgage loans held for sale and forward commitments to sell residential mortgage loans held for sale represented $18.2 million and $6.0 million, respectively, at December 31, 2018. The net fair value of these interest rate lock commitments and forward commitments was a loss of $154,000 at June 30, 2019 compared to a gain of $162,000 at December 31, 2018.

Liquidity Management

Liquidity management refers to the ability to ensure that cash is available in a timely and cost-effective manner to meet cash flow requirements of depositors and borrowers and to meet other commitments as they fall due, including the ability to service debt, invest in subsidiaries, repurchase common stock, pay dividends to shareholders (if any), and satisfy other operating requirements.

Funds are available from a number of basic banking activity sources including, but not limited to, the core deposit base; repayment and maturity of loans; investment securities calls, maturities, and sales; and procurement of brokered deposits or other wholesale funding. All securities AFS and equity securities (included in other investments) are reported at fair value on the consolidated balance sheet. At June 30, 2019, approximately 33% of the $404 million securities AFS portfolio was pledged to secure public deposits and short-term borrowings, as applicable, and for other purposes as required by law. Additional funding sources at June 30, 2019, consist of a $10 million available and unused line of credit at the holding company, $175 million of available and unused Federal funds lines, available borrowing capacity at the FHLB of $170 million, and borrowing capacity in the brokered deposit market.

Cash and cash equivalents at June 30, 2019 and December 31, 2018 were $155 million and $250 million, respectively. The decrease in cash and cash equivalents since year-end 2018 was largely attributable to loan growth, a reduction in deposits, and common stock purchases, partially offset by earnings. Nicolet’s liquidity resources were sufficient as of June 30, 2019 to fund loans, accommodate deposit cycles and trends, and to meet other cash needs as necessary.

Management is committed to the parent Company being a source of strength to the Bank and its other subsidiaries, and therefore, regularly evaluates capital and liquidity positions of the parent Company in light of current and projected needs, growth or strategies. The parent Company uses cash for normal expenses, debt service requirements, and when opportune, for common stock repurchases or investment in other strategic actions such as mergers or acquisitions. Dividends from the Bank and, to a lesser extent, stock

41

option exercises, represent significant sources of cash flows for the parent Company. Among others, additional cash sources available to the parent Company include its $10 million available and unused line of credit, and access to the public or private markets to issue new equity, subordinated debt or other debt. At June 30, 2019, the parent Company had $42 million in cash.

Interest Rate Sensitivity Management and Impact of Inflation

A reasonable balance between interest rate risk, credit risk, liquidity risk and maintenance of yield, is highly important to Nicolet’s business success and profitability. As an ongoing part of its financial strategy and risk management, Nicolet attempts to understand and manage the impact of fluctuations in market interest rates on its net interest income. The consolidated balance sheet consists mainly of interest-earning assets (loans, investments and cash) which are primarily funded by interest-bearing liabilities (deposits and other borrowings). Such financial instruments have varying levels of sensitivity to changes in market rates of interest. Market rates are highly sensitive to many factors beyond our control, including but not limited to general economic conditions and policies of governmental and regulatory authorities. Our operating income and net income depends, to a substantial extent, on “rate spread” (i.e., the difference between the income earned on loans, investments and other earning assets and the interest expense paid to obtain deposits and other funding liabilities).

Asset-liability management policies establish guidelines for acceptable limits on the sensitivity to changes in interest rates on earnings and market value of assets and liabilities. Such policies are set and monitored by management and the board of directors’ Asset and Liability Committee.

To understand and manage the impact of fluctuations in market interest rates on net interest income, Nicolet measures its overall interest rate sensitivity through a net interest income analysis, which calculates the change in net interest income in the event of hypothetical changes in interest rates under different scenarios versus a baseline scenario. Such scenarios can involve static balance sheets, balance sheets with projected growth, parallel (or non-parallel) yield curve slope changes, immediate or gradual changes in market interest rates, and one-year or longer time horizons. The simulation modeling uses assumptions involving market spreads, prepayments of rate-sensitive instruments, renewal rates on maturing or new loans, deposit retention rates, and other assumptions.

Nicolet assessed the impact on net interest income in the event of a gradual +/-100 bps and +/-200 bps change in market rates (parallel to the change in prime rate) over a one-year time horizon to a static (flat) balance sheet. The interest rate scenarios are used for analytical purposes only and do not necessarily represent management’s view of future market interest rate movements. Based on financial data at June 30, 2019 and December 31, 2018, the projected changes in net interest income over a one-year time horizon, versus the baseline, are presented in Table 11 below. The results are within Nicolet’s guidelines of not greater than -10% for +/- 100 bps and not greater than -15% for +/- 200 bps.

Table 11: Interest Rate Sensitivity

	June 30, 2019		December 31, 2018
200 bps decrease in interest rates	(2.4	)%	(0.6	)%
100 bps decrease in interest rates	(1.1	)%	—	%
100 bps increase in interest rates	1.1	%	(0.1	)%
200 bps increase in interest rates	2.2	%	—	%

Actual results may differ from these simulated results due to timing, magnitude and frequency of interest rate changes, as well as changes in market conditions and their impact on customer behavior and management strategies.

The effect of inflation on a financial institution differs significantly from the effect on an industrial company. While a financial institution’s operating expenses, particularly salary and employee benefits, are affected by general inflation, the asset and liability structure of a financial institution consists largely of monetary items. Monetary items, such as cash, investments, loans, deposits and other borrowings, are those assets and liabilities which are or will be converted into a fixed number of dollars regardless of changes in prices. As a result, changes in interest rates have a more significant impact on a financial institution’s performance than does general inflation.

Capital

Management regularly reviews the adequacy of its capital to ensure that sufficient capital is available for current and future needs and is in compliance with regulatory guidelines and actively reviews capital strategies in light of perceived business risks associated with current and prospective earning levels, liquidity, asset quality, economic conditions in the markets served, and level of returns available to shareholders. Management intends to maintain an optimal capital and leverage mix for growth and shareholder return.

Nicolet’s intent is to maintain capital levels for the Company and the Bank at amounts in excess of the regulatory well-capitalized thresholds. At June 30, 2019, the Bank’s regulatory capital ratios qualify the Bank as well-capitalized under the prompt-corrective action framework. This strong base of capital has allowed Nicolet to be opportunistic in the current environment and in strategic growth. A summary of Nicolet’s and the Bank’s regulatory capital amounts and ratios, as well as selected capital metrics are presented in the following table.

In managing capital for optimal return, we evaluate capital sources and uses, pricing and availability of our stock in the market, and alternative uses of capital (such as the level of organic growth or acquisition opportunities) in light of strategic plans. During first half 2019, $14.7 million was utilized to repurchase and cancel 253,753 shares of common stock pursuant to our common stock repurchase program. On June 18, 2019, Nicolet's board authorized an increase to the program of $20 million or up to 325,000 shares of common stock. As a result, at June 30, 2019, there remains $25.0 million authorized under the repurchase program to be utilized from time-to-time to repurchase shares in the open market, through block transactions or in private transactions.

Critical Accounting Policies

In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheet and revenues and expenses for the period. Actual results could differ significantly from those estimates. Estimates that are particularly susceptible to significant change include the valuation of loan acquisition transactions, as well as the determination of the allowance for loan losses and income taxes. A discussion of these policies can be found in the “Critical Accounting Policies” section in Management’s Discussion and Analysis of Financial Condition and Results of Operations included in the Company’s 2018 Annual Report on Form 10-K. There have been no changes in the Company’s application of critical accounting policies since December 31, 2018.

Future Accounting Pronouncements

Recent accounting pronouncements adopted are included in Note 1, “Basis of Presentation” of the Notes to Unaudited Consolidated Financial Statements within Part I, Item 1.

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement. This ASU modifies the disclosure requirements for fair value measurements by removing, modifying or adding certain disclosures. The updated guidance is effective for annual reporting periods, including interim periods within those fiscal years, beginning after December 15, 2019, with early adoption permitted. As the new ASU only revises disclosure requirements, it is not expected to have a material impact on the Company's consolidated financial statements.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments intended to improve the financial reporting by requiring earlier recognition of credit losses on loans and certain other financial assets. Topic 326 replaces the current incurred loss impairment model (which recognizes losses when a probable threshold is met) with a requirement to recognize lifetime expected credit losses immediately when a financial asset is originated or purchased. The measurement of lifetime expected credit losses will be based on historical experience, current

43

conditions, and reasonable and supportable forecasts. The ASU is effective for SEC filers for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Entities should apply the amendment by means of a cumulative-effect adjustment to retained earnings as of the beginning of the fiscal year of adoption. Early application is permitted for all organizations for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The Company expects to adopt the new accounting standard in 2020, as required. Nicolet established a cross-functional team to assess the impact of the new guidance on its consolidated financial statements and implement the new standard. This team continues to make progress on developing credit models, model validation and testing, as well as accounting, reporting, and governance processes to comply with the new credit loss requirements.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

See section “Interest Rate Sensitivity Management and Impact of Inflation” within Management’s Discussion and Analysis of Financial Condition and Results of Operations under Part I, Item 2.

ITEM 4. CONTROLS AND PROCEDURES

As of the end of the period covered by this report, management, under the supervision, and with the participation, of our Chairman, President and Chief Executive Officer and our Chief Financial Officer, evaluated the effectiveness of the design and operation of our disclosure controls and procedures (as such term is defined in Rule 13a-15(e) and 15d-15(e) under the Exchange Act pursuant to Exchange Act Rule 13a-15). Based upon, and as of the date of such evaluation, the Chairman, President and Chief Executive Officer and the Chief Financial Officer concluded that our disclosure controls and procedures were effective.

There have been no changes in the Company’s internal controls or, to the Company’s knowledge, in other factors during the quarter covered by this report that have materially affected, or are reasonably likely to materially affect, the Company’s internal controls over financial reporting. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation

General

In the opinion of management, the accompanying unaudited consolidated financial statements contain all adjustments necessary to present fairly the consolidated balance sheets, statements of income, comprehensive income, changes in stockholders’ equity and cash flows of Nicolet Bankshares, Inc. (the “Company” or “Nicolet”) and its subsidiaries, for the periods presented, and all such adjustments are of a normal recurring nature. All material intercompany transactions and balances have been eliminated. The results of operations for the interim periods are not necessarily indicative of the results to be expected for the entire year.

These interim consolidated financial statements have been prepared according to the rules and regulations of the Securities and Exchange Commission and, therefore, certain information and footnote disclosures normally presented in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) have been omitted or abbreviated. These consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and footnotes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018.

Critical Accounting Policies and Estimates

Preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying disclosures. These estimates are based on management’s best knowledge of current events and actions the Company may undertake in the future. Estimates are used in accounting for, among other items, the allowance for loan losses, valuation of loans in acquisition transactions, useful lives for depreciation and amortization, fair value of financial instruments, other-than-temporary impairment calculations, valuation of deferred tax assets, uncertain income tax positions and contingencies. Estimates that are particularly susceptible to significant change for the Company include the determination of the allowance for loan losses, the determination and assessment of deferred tax assets and liabilities, and the valuation of loans acquired in acquisition transactions; therefore, these are critical accounting policies. Factors that may cause sensitivity to the aforementioned estimates include but are not limited to: external market factors such as market interest rates and employment rates, changes to operating policies and procedures, changes in applicable banking or tax regulations, and changes to deferred tax estimates. Actual results may ultimately differ from estimates, although management does not generally believe such differences would materially affect the consolidated financial statements in any individual reporting period presented.

There have been no material changes or developments with respect to the assumptions or methodologies that the Company uses when applying what management believes are critical accounting policies and developing critical accounting estimates as disclosed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018.

Recent Accounting Developments Adopted

In August 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. ASU 2017-12 expands the activities that qualify for hedge accounting and simplifies the rules for reporting hedging transactions. The updated guidance is effective for interim and annual reporting periods beginning after December 15, 2018, with early adoption permitted. The Company adopted the updated guidance effective January 1, 2019 with no material impact on its consolidated financial statements, because the Company does not have any significant derivatives and does not currently apply hedge accounting to derivatives.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), with several subsequent updates. Topic 842 introduced a new accounting model for lessors and lessees. For lessees, almost all leases are now recognized on the balance sheet as a right-of-use ("ROU") asset and lease liability, unlike previous GAAP which required only capital leases to be recognized on the balance sheet. The accounting applied by lessors is largely unchanged from existing guidance. Topic 842 also requires additional disclosures concerning the amount, timing and uncertainty of cash flows arising from leases. The updated guidance is effective for annual reporting periods beginning after December 15, 2018, and provides a modified retrospective transition approach that allows lessees to recognize and measure leases on the balance sheet at the beginning of either the earliest period presented or as of the beginning of the period of adoption (the "effective date" method), with the option to elect certain practical expedients. Nicolet adopted the new guidance prospectively as of January 1, 2019, using the effective date method; thus, prior comparative periods have not been restated.

Upon adoption, Nicolet recognized an ROU asset and lease liability of approximately $5 million. There was no impact to its consolidated statements of income or cash flows compared to the prior lease accounting model. The ROU asset and lease liability are recorded in other assets and other liabilities, respectively, in the consolidated balance sheets. As part of the adoption, Nicolet elected the package of practical expedients permitted under the transition guidance of the new standard which allowed the carry forward of the historical lease classification. Nicolet also elected the practical expedient to group lease and non-lease components as a single lease component; thus, the Company's leases include both lease (e.g., fixed payments including rent, taxes, and insurance costs) and non-lease components (e.g., common area or other maintenance costs). See Note 10 for the new disclosures required by Topic 842.

Reclassifications

Certain amounts in the 2018 consolidated financial statements have been reclassified to conform to the 2019 presentation.

Earnings per Common Share

Earnings per Common Share

Basic earnings per common share are calculated by dividing net income available to common shareholders by the weighted average number of common shares outstanding during the period. Diluted earnings per common share are calculated by dividing net income available to common shareholders by the weighted average number of shares adjusted for the dilutive effect of common stock awards (outstanding stock options and unvested restricted stock), if any. Presented below are the calculations for basic and diluted earnings per common share.

*Cumulative quarterly per share performance may not equal annual per share totals due to the effects of the amount and timing of capital increases. When computing earnings per share for an interim period, the denominator is based on the weighted average shares outstanding during the interim period, and not on an annualized weighted average basis. Accordingly, the sum of the earnings per share data for the quarters will not necessarily equal the year to date earnings per share data.

For the three and six months endedJune 30, 2019, options to purchase less than 0.1 million shares are excluded from the calculation of diluted earnings per common share as the effect of their exercise would have been anti-dilutive. For the three and six months endedJune 30, 2018, options to purchase approximately 0.1 million shares are excluded from the calculation of diluted earnings per common share as the effect of their exercise would have been anti-dilutive.

Stock-Based Compensation

Stock-Based Compensation

Stock-Based Compensation

The Company may grant stock options and restricted stock under its stock-based compensation plans to certain officers, employees and directors. These plans are administered by a committee of the Board of Directors. In February 2019, with subsequent shareholder approval, the 2011 Long-Term Incentive Plan was amended to increase the shares reserved for potential stock-based awards from 1,500,000 shares to 3,000,000 shares. At June 30, 2019, approximately 1.6 million shares were available for grant under these stock-based compensation plans.

A Black-Scholes model is utilized to estimate the fair value of stock option grants, while the market price of the Company’s stock at the date of grant is used to estimate the fair value of restricted stock awards. The weighted average assumptions used in the Black-Scholes model for valuing stock option grants were as follows.

Exercisable - June 30, 2019	667,418		$	38.34	6.5	$	15,833

* The terms of the stock option agreements permit having a number of shares of stock withheld, the fair market value of which as of the date of exercise is sufficient to satisfy the exercise price and/or tax withholding requirements. For the six months endedJune 30, 2019, 64,681 such shares were surrendered to the Company.

Intrinsic value represents the amount by which the fair market value of the underlying stock exceeds the exercise price of the stock options. The intrinsic value of options exercised for the six months endedJune 30, 2019 and 2018 was approximately $5.0 million and $1.4 million, respectively.

A summary of the Company’s restricted stock activity is summarized below.

Restricted Stock	Weighted Average Grant Date Fair Value		Restricted Shares Outstanding
Outstanding - December 31, 2018	$	39.37	29,512
Granted	61.96		4,257

Forfeited	16.50		(408	)
Outstanding - June 30, 2019	$	41.64	23,939

* The terms of the restricted stock agreements permit the surrender of shares to the Company upon vesting in order to satisfy applicable tax withholding requirements at the minimum statutory withholding rate, and accordingly, 1,553 shares were surrendered during the six months endedJune 30, 2019.

The Company recognized approximately $2.2 million and $2.3 million of stock-based compensation expense (included in personnel on the consolidated statements of income) during the six months endedJune 30, 2019 and 2018, respectively, associated with its common stock awards granted to officers and employees. In addition, during the first half of 2019, the Company recognized approximately $0.3 million of director expense (included in other expense on the consolidated statements of income) for a total restricted stock grant of 4,257 shares with immediate vesting to directors. As of June 30, 2019, there was approximately $11.0 million of unrecognized compensation cost related to equity award grants. The cost is expected to be recognized over the remaining vesting period of approximately three years. The Company recognized a tax benefit of approximately $0.9 million and $0.2 million for the six months ended June 30, 2019 and 2018, respectively, for the tax impact of stock option exercises and vesting of restricted stock.

As of June 30, 2019, the Company does not consider its securities AFS with unrealized losses to be other-than-temporarily impaired, as the unrealized losses in each category have occurred as a result of changes in interest rates, market spreads and market conditions subsequent to purchase, not credit deterioration. The Company has the ability and intent to hold its securities to maturity. There were no other-than-temporary impairments charged to earnings during the six months endedJune 30, 2019 or 2018.

The amortized cost and fair value of securities AFS by contractual maturity are shown below. Expected maturities may differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties; as this is particularly inherent in mortgage-backed securities, these securities are not included in the maturity categories below.

Practically all of the Company’s loans, commitments, and letters of credit have been granted to customers in the Company’s market area. Although the Company has a diversified loan portfolio, the credit risk in the loan portfolio is largely influenced by general economic conditions and trends of the counties and markets in which the debtors operate, and the resulting impact on the operations of borrowers or on the value of underlying collateral, if any.

A roll forward of the allowance for loan losses is summarized as follows.

A description of the loan risk categories used by the Company follows.

Grades 1-4, Pass: Credits exhibit adequate cash flows, appropriate management and financial ratios within industry norms and/or are supported by sufficient collateral. Some credits in these rating categories may require a need for monitoring but elements of concern are not severe enough to warrant an elevated rating.

Grade 5, Watch: Credits with this rating are adequately secured and performing but are being monitored due to the presence of various short-term weaknesses which may include unexpected, short-term adverse financial performance, managerial problems, potential impact of a decline in the entire industry or local economy and delinquency issues. Loans to individuals or loans supported by guarantors with marginal net worth or collateral may be included in this rating category.

Grade 6, Special Mention: Credits with this rating have potential weaknesses that, without the Company’s attention and correction may result in deterioration of repayment prospects. These assets are considered Criticized Assets. Potential weaknesses may include adverse financial trends for the borrower or industry, repeated lack of compliance with Company requests, increasing debt to net worth, serious management conditions and decreasing cash flow.

Grade 7, Substandard: Assets with this rating are characterized by the distinct possibility the Company will sustain some loss if deficiencies are not corrected. All foreclosures, liquidations, and nonaccrual loans are considered to be categorized in this rating, regardless of collateral sufficiency.

Grade 8, Doubtful: Assets with this rating exhibit all the weaknesses as one rated Substandard with the added characteristic that such weaknesses make collection or liquidation in full highly questionable.

Grade 9, Loss: Assets in this category are considered uncollectible. Pursuing any recovery or salvage value is impractical but does not preclude partial recovery in the future.

Goodwill and Intangible Assets Disclosure [Abstract]

Goodwill and Other Intangibles and Mortgage Servicing Rights

Goodwill and Other Intangibles and Mortgage Servicing Rights

Management periodically reviews the carrying value of its intangible assets to determine if any impairment has occurred, in which case an impairment charge would be recorded as an expense in the period of impairment, or whether changes in circumstances have occurred that would require a revision to the remaining useful life which would impact expense prospectively. In making such determination, management evaluates whether there are any adverse qualitative factors indicating that an impairment may exist, as well as the performance, on an undiscounted basis, of the underlying operations or assets which give rise to the intangible. The Company’s quarterly assessment indicated no impairment charge on goodwill, core deposit intangibles or customer list intangibles was required for the year ended December 31, 2018 or the six months endedJune 30, 2019. A summary of goodwill and other intangibles was as follows.

Goodwill: Goodwill was $107.4 million at both June 30, 2019 and December 31, 2018.

Other intangible assets: Other intangible assets, consisting of core deposit intangibles and customer list intangibles, are amortized over their estimated finite lives.

Mortgage servicing rights: Mortgage servicing rights are amortized in proportion to and over the period of estimated net servicing income, and assessed for impairment at each reporting date, with the amortization recorded in mortgage income, net, in the consolidated statements of income. Mortgage servicing rights are carried at the lower of the initial capitalized amount, net of accumulated amortization, or estimated fair value, and are included in other assets in the consolidated balance sheets. A summary of the changes in the mortgage servicing rights asset was as follows.

Net book value of MSR asset to loans serviced for others	0.64		%	0.62		%

The Company periodically evaluates its mortgage servicing rights asset for impairment. At each reporting date, impairment is assessed based on estimated fair value using estimated prepayment speeds of the underlying mortgage loans serviced and stratifications based on the risk characteristics of the underlying loans (predominantly loan type and note interest rate). No valuation allowance or impairment charge was recorded for the year ended December 31, 2018 or the six months endedJune 30, 2019. See Note 9 for additional information on the fair value of the MSR asset.

The following table shows the estimated future amortization expense for amortizing intangible assets and the MSR asset. The projections are based on existing asset balances, the current interest rate environment and prepayment speeds as of June 30, 2019. The actual amortization expense the Company recognizes in any given period may be significantly different depending upon acquisition or sale activities, changes in interest rates, prepayment speeds, market conditions, regulatory requirements and events or circumstances that indicate the carrying amount of an asset may not be recoverable.

Fair Value Disclosures [Abstract]

Fair Value Measurements

Fair Value Measurements

Fair value represents the estimated price at which an orderly transaction to sell an asset or transfer a liability would take place between market participants at the measurement date under current market conditions (i.e., an exit price concept), and is a market-based measurement versus an entity-specific measurement.

The Company records and/or discloses financial instruments on a fair value basis. These financial assets and financial liabilities are measured at fair value in three levels, based on the markets in which the assets and liabilities are traded and the observability of the assumptions used to determine fair value. These levels are:

• Level 1 – quoted market prices in active markets for identical assets or liabilities that a company has the ability to access at the measurement date

• Level 2 – inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly

• Level 3 – significant unobservable inputs for the asset or liability, which are typically based on an entity’s own assumptions, as there is little, if any, related market activity

In instances where the fair value measurement is based on inputs from different levels, the level within which the entire fair value measurement will be categorized is based on the lowest level input that is significant to the fair value measurement in its entirety. This assessment of the significance of an input requires management judgment.

Recurring basis fair value measurements:

The following table presents the balances of assets and liabilities measured at fair value on a recurring basis for the periods presented.

Other investments (equity securities)	$	2,650	$	2,650	$	—	$	—

The following is a description of the valuation methodologies used by the Company for the securities AFS and equity securities measured at fair value on a recurring basis, noted in the tables above. Where quoted market prices on securities exchanges are available, the investments are classified as Level 1. Level 1 investments primarily include exchange-traded equity securities. If quoted market prices are not available, fair value is generally determined using prices obtained from independent pricing vendors who use pricing models (with typical inputs including benchmark yields, reported trades for similar securities, issuer spreads or relationship to other benchmark quoted securities), or discounted cash flows, and are classified as Level 2. Examples of these investments include U.S. government agency securities, mortgage-backed securities, obligations of state, county and municipals, and certain corporate debt securities. Finally, in certain cases where there is limited activity or less transparency around inputs to the estimated fair value, investments are classified within Level 3 of the hierarchy. Examples of these include private municipal bonds and corporate debt securities, which include trust preferred security investments. At June 30, 2019 and December 31, 2018, it was determined that carrying value was the best approximation of fair value for these Level 3 securities, based primarily on the internal analysis on these securities.

The following table presents the changes in the Level 3 securities AFS measured at fair value on a recurring basis.

Nonrecurring basis fair value measurements:

The following table presents the Company’s assets measured at fair value on a nonrecurring basis, aggregated by level in the fair value hierarchy within which those measurements fall.

OREO	420		—		—		420
MSR asset	6,347		—		—		6,347

The following is a description of the valuation methodologies used by the Company for the items noted in the table above. For individually evaluated impaired loans, the amount of impairment is based upon the present value of expected future cash flows discounted at the loan’s effective interest rate, the estimated fair value of the underlying collateral for collateral-dependent loans, or the estimated liquidity of the note. For OREO, the fair value is based upon the estimated fair value of the underlying collateral adjusted for the expected costs to sell. To estimate the fair value of the MSR asset, the underlying serviced loan pools are stratified by interest rate tranche and term of the loan, and a valuation model is used to calculate the present value of the expected future cash flows for each stratum. The valuation model incorporates assumptions that market participants would use in estimating future net servicing income, such as costs to service, a discount rate, ancillary income, default rates and losses, and prepayment speeds. Although some of these assumptions are based on observable market data, other assumptions are based on unobservable estimates of what market participants would use to measure fair value.

The carrying value of certain assets and liabilities such as cash and cash equivalents, BOLI, and nonmaturing deposits, approximate their estimated fair value. For those financial instruments not previously disclosed, the following is a description of the valuation methodologies used.

Certificates of deposits in other banks: Fair values are estimated using discounted cash flow analysis based on current interest rates being offered by instruments with similar terms and represents a Level 2 measurement.

Other investments: The valuation methodologies utilized for exchange-traded equity securities are discussed under “Recurring basis fair value measurements” above. The carrying amount of Federal Reserve Bank and FHLB stock is a reasonably accepted fair value estimate given their restricted nature. Fair value is the redeemable (carrying) value based on the redemption provisions of the instruments which is considered a Level 2 measurement. The carrying amount of the remaining other investments (particularly common stocks of companies or other banks that are not publicly traded) approximates their fair value, determined primarily by analysis of company financial statements and recent capital issuances of the respective companies or banks, if any, and represents a Level 3 measurement.

Loans held for sale: The fair value estimation process for the loans held for sale portfolio is segregated by loan type. The estimated fair value was based on what secondary markets are currently offering for portfolios with similar characteristics and represents a Level 2 measurement.

Loans, net: For variable-rate loans that reprice frequently and with no significant change in credit risk or other optionality, fair values are based on carrying values. Fair values for all other loans are estimated by discounting contractual cash flows using estimated market discount rates, which reflect the credit and interest rate risk inherent in the loan. Collateral-dependent impaired loans are included in loans, net. The fair value of loans is considered to be a Level 3 measurement due to internally developed discounted cash flow measurements.

Deposits: The fair value of deposits with no stated maturity (such as demand deposits, savings, interest and noninterest checking, and money market accounts) is, by definition, equal to the amount payable on demand at the reporting date. Fair values for fixed-rate certificates of deposit are estimated using a discounted cash flow calculation that applies interest rates currently being offered in the market place on certificates of similar remaining maturities. Use of internal discounted cash flows provides a Level 3 fair value measurement.

Long-term borrowings: The fair value of the FHLB advances is obtained from the FHLB which uses a discounted cash flow analysis based on current market rates of similar maturity debt securities and represents a Level 2 measurement. The fair values of the junior subordinated debentures and subordinated notes utilize a discounted cash flow analysis based on an estimate of current interest rates being offered by instruments with similar terms and credit quality. Since the market for these instruments is limited, the internal evaluation represents a Level 3 measurement.

Lending-related commitments and derivative financial instruments: At June 30, 2019 and December 31, 2018, the estimated fair value of letters of credit, interest rate lock commitments on residential mortgage loans, outstanding mandatory commitments to sell residential mortgage loans into the secondary market, and mirror interest rate swap agreements were not significant.

Limitations: Fair value estimates are made at a specific point in time, based on relevant market information and information about the financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale at one time the Company’s entire holdings of a particular financial instrument. Fair value estimates may not be realizable in an immediate settlement of the instrument. In some instances, there are no quoted market prices for the Company’s various financial instruments, in which case fair values may be based on estimates using present value or other valuation techniques, or based on judgments regarding future expected loss experience, current economic conditions, risk characteristics of the financial instruments, or other factors. Those techniques are significantly affected by the assumptions used, including the discount rate and estimate of future cash flows. Subsequent changes in assumptions could significantly affect the estimates.

Leases [Abstract]

Operating Leases

Operating Leases

As of January 1, 2019, the Company adopted ASU 2016-02 (Topic 842) on a prospective basis using the effective date method. The adoption of the new standard did not have a material impact on Nicolet's financial statements; however, additional disclosures have been added in accordance with the ASU. See Note 1 for additional information on this new accounting standard.

The operating lease ROU asset represents the right to use an underlying asset during the lease term, while the operating lease liability represents the obligation to make lease payments arising from the lease. The ROU asset and lease liability are recognized at lease commencement based on the present value of the remaining lease payments, considering a discount rate that represents Nicolet's incremental borrowing rate. Operating lease expense is recognized on a straight-line basis over the lease term and is recognized in occupancy, equipment, and office on the consolidated statements of income.

Nicolet leases space under non-cancelable operating lease agreements for certain bank and nonbank branch facilities with remaining lease terms of 2 to 7 years. Certain lease arrangements contain extension options which typically range from 5 to 10 years at the then fair market rental rates. The lease asset and liability considers renewal options when they are reasonably certain of being exercised.

A summary of net lease cost and selected other information related to operating leases was as follows.

Accounting Policies [Abstract]

General

General

In the opinion of management, the accompanying unaudited consolidated financial statements contain all adjustments necessary to present fairly the consolidated balance sheets, statements of income, comprehensive income, changes in stockholders’ equity and cash flows of Nicolet Bankshares, Inc. (the “Company” or “Nicolet”) and its subsidiaries, for the periods presented, and all such adjustments are of a normal recurring nature. All material intercompany transactions and balances have been eliminated. The results of operations for the interim periods are not necessarily indicative of the results to be expected for the entire year.

These interim consolidated financial statements have been prepared according to the rules and regulations of the Securities and Exchange Commission and, therefore, certain information and footnote disclosures normally presented in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) have been omitted or abbreviated. These consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and footnotes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018.

Critical Accounting Policies and Estimates

Critical Accounting Policies and Estimates

Preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying disclosures. These estimates are based on management’s best knowledge of current events and actions the Company may undertake in the future. Estimates are used in accounting for, among other items, the allowance for loan losses, valuation of loans in acquisition transactions, useful lives for depreciation and amortization, fair value of financial instruments, other-than-temporary impairment calculations, valuation of deferred tax assets, uncertain income tax positions and contingencies. Estimates that are particularly susceptible to significant change for the Company include the determination of the allowance for loan losses, the determination and assessment of deferred tax assets and liabilities, and the valuation of loans acquired in acquisition transactions; therefore, these are critical accounting policies. Factors that may cause sensitivity to the aforementioned estimates include but are not limited to: external market factors such as market interest rates and employment rates, changes to operating policies and procedures, changes in applicable banking or tax regulations, and changes to deferred tax estimates. Actual results may ultimately differ from estimates, although management does not generally believe such differences would materially affect the consolidated financial statements in any individual reporting period presented.

There have been no material changes or developments with respect to the assumptions or methodologies that the Company uses when applying what management believes are critical accounting policies and developing critical accounting estimates as disclosed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018.

Recent Accounting Developments Adopted

Recent Accounting Developments Adopted

In August 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. ASU 2017-12 expands the activities that qualify for hedge accounting and simplifies the rules for reporting hedging transactions. The updated guidance is effective for interim and annual reporting periods beginning after December 15, 2018, with early adoption permitted. The Company adopted the updated guidance effective January 1, 2019 with no material impact on its consolidated financial statements, because the Company does not have any significant derivatives and does not currently apply hedge accounting to derivatives.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), with several subsequent updates. Topic 842 introduced a new accounting model for lessors and lessees. For lessees, almost all leases are now recognized on the balance sheet as a right-of-use ("ROU") asset and lease liability, unlike previous GAAP which required only capital leases to be recognized on the balance sheet. The accounting applied by lessors is largely unchanged from existing guidance. Topic 842 also requires additional disclosures concerning the amount, timing and uncertainty of cash flows arising from leases. The updated guidance is effective for annual reporting periods beginning after December 15, 2018, and provides a modified retrospective transition approach that allows lessees to recognize and measure leases on the balance sheet at the beginning of either the earliest period presented or as of the beginning of the period of adoption (the "effective date" method), with the option to elect certain practical expedients. Nicolet adopted the new guidance prospectively as of January 1, 2019, using the effective date method; thus, prior comparative periods have not been restated.

Upon adoption, Nicolet recognized an ROU asset and lease liability of approximately $5 million. There was no impact to its consolidated statements of income or cash flows compared to the prior lease accounting model. The ROU asset and lease liability are recorded in other assets and other liabilities, respectively, in the consolidated balance sheets. As part of the adoption, Nicolet elected the package of practical expedients permitted under the transition guidance of the new standard which allowed the carry forward of the historical lease classification. Nicolet also elected the practical expedient to group lease and non-lease components as a single lease component; thus, the Company's leases include both lease (e.g., fixed payments including rent, taxes, and insurance costs) and non-lease components (e.g., common area or other maintenance costs). See Note 10 for the new disclosures required by Topic 842.

Earnings Per Share [Abstract]

Schedule of basic and diluted earnings (loss) per common share

Presented below are the calculations for basic and diluted earnings per common share.

	Three Months Ended June 30,				Six Months Ended June 30,
(In thousands, except per share data)	2019		2018		2019		2018
Net income attributable to Nicolet Bankshares, Inc.	$	18,549	$	9,737	$	28,816	$	19,314
Weighted average common shares outstanding	9,374		9,639		9,418		9,702
Effect of dilutive common stock awards	318		331		293		330
Diluted weighted average common shares outstanding	9,692		9,970		9,711		10,032

Diluted earnings per common share*	$	1.91	$	0.98	$	2.97	$	1.93

*Cumulative quarterly per share performance may not equal annual per share totals due to the effects of the amount and timing of capital increases. When computing earnings per share for an interim period, the denominator is based on the weighted average shares outstanding during the interim period, and not on an annualized weighted average basis. Accordingly, the sum of the earnings per share data for the quarters will not necessarily equal the year to date earnings per share data.
