Forward-looking statements are based on current management expectations and, by their nature, are subject to risks and uncertainties. These statements are neither statements of historical fact nor assurance of future performance and generally may be identified by the use of words such as “believe,” “expect,” “anticipate,” “plan,” “estimate,” “should,” “will,” “intend,” or similar expressions. Forward-looking statements include discussions of strategy, financial projections, guidance and estimates (including their underlying assumptions), statements regarding plans, objectives, expectations or consequences of various transactions or events, and statements about our future performance, operations, products and services, and should be viewed with caution. Shareholders should note that many factors, some of which are discussed elsewhere in this document, could affect the future financial results of Nicolet and could cause those results to differ materially from those implied or anticipated by the statements. Except as required by law, we expressly disclaim any obligations to publicly update any forward-looking statements whether written or oral, that may be made from time to time, whether as a result of new information, future developments or otherwise. Important factors, many of which are beyond Nicolet’s control that could cause our actual results and financial condition to differ materially from those indicated in the forward-looking statements, in addition to those described in detail under Item 1A of this Report, “Risk Factors”, include but are not necessarily limited to the following:

•the COVID-19 pandemic and its continuing effects on our business (including the diversion of management time and resources) as well as the business, customers, employees and third-party service providers of Nicolet or any of its acquisition targets;

•operating, legal and regulatory risks, including the effects of legislative or regulatory developments affecting the financial industry generally or Nicolet specifically;

•economic, market, political and competitive forces affecting Nicolet’s banking and wealth management businesses;

•changes in interest rates, monetary policy and general economic conditions, which may impact Nicolet’s net interest income;

•potential difficulties in identifying and integrating the operations of future acquisition targets with those of Nicolet;

•cybersecurity risks and the vulnerability of our network and online banking portals, and the systems or parties with whom we contract, to unauthorized access, computer viruses, phishing schemes, spam attacks, human error, natural disasters, power loss and other security breaches that could adversely affect our business and financial performance or reputation;

•changes in accounting standards, rules and interpretations and the related impact on Nicolet’s financial statements;

•compliance or operational risks related to new products, services, ventures, or lines of business, if any, that Nicolet may pursue or implement;

•changes in monetary and tax policies;

•changes occurring in business conditions and inflation;

•our ability to attract and retain key personnel;

•examinations by our regulatory authorities, including the possibility that the regulatory authorities may, among other things, require us to increase our allowance for credit losses, write-down assets, or take other actions;

•risks associated with actual or potential information gatherings, investigations or legal proceedings by customers, regulatory agencies or others;

•the potential effects of events beyond our control that may have a destabilizing effect on financial markets and the economy, such as weather events, natural disasters, epidemics and pandemics (including COVID-19), war or terrorist activities, disruptions in our customers’ supply chains, disruptions in transportation, essential utility outages or trade disputes and related tariffs;

•each of the factors and risks under the heading “Risk Factors” in our 2021 Annual Report on Form 10-K and in subsequent filings we make with the SEC; and

•the risk that Nicolet’s analysis of these risks and forces could be incorrect and/or that the strategies developed to address them could be unsuccessful.

These factors should be considered in evaluating the forward-looking statements, and you should not place undue reliance on such statements.

ITEM 1. BUSINESS

General

Nicolet Bankshares, Inc. (individually referred to herein as the “Parent Company” and together with all its subsidiaries collectively referred to herein as “Nicolet,” the “Company,” “we,” “us” or “our”) is a registered bank holding company under the Bank Holding Company Act of 1956, as amended, and under the bank holding company laws of the State of Wisconsin. At December 31, 2021, Nicolet had total assets of $7.7 billion, loans of $4.6 billion, deposits of $6.5 billion and total stockholders’ equity of $892 million. For the year ended December 31, 2021, Nicolet earned net income of $61 million, or $5.44 per diluted common share.

Nicolet was founded upon five core values (Be Real, Be Responsive, Be Personal, Be Memorable, and Be Entrepreneurial) which are embodied within each of our employees and create a distinct competitive positioning in the markets within which we operate. Our mission is to be the lead community bank within the communities we serve, while our vision is to optimize the long-term return to our customers and communities, employees and shareholders (the “3 Circles”).

The Parent Company is a Wisconsin corporation, originally incorporated on April 5, 2000 as Green Bay Financial Corporation, a Wisconsin corporation, to serve as the holding company for and the sole shareholder of Nicolet National Bank. The Parent Company amended and restated its articles of incorporation and changed its name to Nicolet Bankshares, Inc. on March 14, 2002. It subsequently became the holding company for Nicolet National Bank upon the completion of the bank’s reorganization into a holding company structure on June 6, 2002. Nicolet elected to become a financial holding company in 2008.

Nicolet conducts its primary operations through its wholly owned subsidiary, Nicolet National Bank, a commercial bank which was organized in 2000 as a national bank under the laws of the United States and opened for business, in Green Bay, Wisconsin, on November 1, 2000 (referred to herein as the “Bank”). At December 31, 2021, the Parent Company also wholly owns a registered investment advisory firm, Nicolet Advisory Services, LLC (“Nicolet Advisory”), that provides brokerage and investment advisory services to customers, and Nicolet Insurance Services, LLC (“Nicolet Insurance”), acquired in 2021, was formed to facilitate the delivery of a crop insurance product associated with Nicolet’s agricultural lending. At December 31, 2021, the Bank wholly owns an investment subsidiary based in Nevada, an entity that owns the building in which Nicolet is headquartered, and a subsidiary that provides a web-based investment management platform for financial advisor trades and related activity. Other than the Bank, these subsidiaries are closely related to or incidental to the business of banking and none are individually or collectively significant to Nicolet’s financial position or results as of December 31, 2021.

Nicolet’s profitability is significantly dependent upon net interest income (interest income earned on loans and other interest-earning assets such as investments, net of interest expense on deposits and other borrowed funds), and noninterest income sources (including but not limited to service charges on deposits, trust and brokerage fees, card interchange income, and mortgage income from sales of residential mortgages into the secondary market), offset by the level of the provision for credit losses, noninterest expense (largely employee compensation and overhead expenses tied to processing and operating the Bank’s business), and income taxes.

Since its opening in late 2000, though more prominently since 2013, Nicolet has supplemented its organic growth with branch purchase and acquisition transactions. Merger and acquisition (“M&A”) activity has continued to be a source of strong growth for Nicolet, including the successful completion of nine acquisitions since 2012. For information on recent transactions, see Note 2, “Acquisitions,” of the Notes to Consolidated Financial Statements under Part II, Item 8.

Products and Services Overview

Nicolet’s principal business is banking, consisting of lending and deposit gathering, as well as ancillary banking-related products and services, to businesses and individuals of the communities it serves, and the operational support to deliver, fund and manage such banking products and services. Additionally, trust, brokerage and other investment management services predominantly for individuals and retirement plan services for business customers are offered. Nicolet delivers its products and services principally through 52 bank branch locations, online banking, mobile banking and an interactive website. Nicolet’s call center also services customers.

Nicolet offers a variety of loans, deposits and related services to business customers (especially small and medium-sized businesses and professional concerns), including but not limited to: business checking and other business deposit products and cash management services, international banking services, business loans, lines of credit, commercial real estate financing, construction loans, agricultural real estate or production loans, and letters of credit, as well as retirement plan services. Similarly, Nicolet offers a variety of banking products and services to consumers, including but not limited to: residential mortgage loans and mortgage refinancing, home equity loans and lines of credit, residential construction loans, personal loans, checking, savings and money market accounts, various certificates of deposit and individual retirement accounts, safe deposit boxes, and personal brokerage, trust and fiduciary services. Nicolet also provides online services including commercial, retail and trust online banking, automated bill

payment, mobile banking deposits and account access, remote deposit capture, and other services such as wire transfers, debit cards, credit cards, pre-paid gift cards, direct deposit, and official bank checks.

Lending is critical to Nicolet’s balance sheet and earnings potential. Nicolet seeks creditworthy borrowers principally within the geographic area of its branch locations. As a community bank with experienced commercial lenders and residential mortgage lenders, our primary lending function is to make loans in the following categories:

•commercial-related loans, consisting of:

◦commercial, industrial, and business loans and lines;

◦owner-occupied commercial real estate (“owner-occupied CRE”);

◦agricultural (“AG”) production and AG real estate;

◦commercial real estate investment loans (“CRE investment”);

◦construction and land development loans;

•residential real estate loans, consisting of:

◦residential first lien mortgages;

◦residential junior lien mortgages;

◦home equity loans and lines of credit;

◦residential construction loans; and

•other loans (mainly consumer in nature).

Lending involves credit risk. Nicolet has and follows extensive loan policies and procedures to standardize processes, meet compliance requirements and prudently manage underwriting, credit and other risks. Credit risk is further controlled and monitored through active asset quality management including the use of lending standards, thorough review of current and potential borrowers through Nicolet’s underwriting process, close relationships with and regular check-ins with borrowers, and active asset quality administration. For further discussion of the loan portfolio composition and credit risk management, see “Management’s Discussion and Analysis of Financial Condition and Results of Operation,” under Part II, Item 7.

Human Capital Resources

At December 31, 2021, Nicolet had 856 full-time equivalent employees and 876 headcount employees. None of our employees are represented by unions.

As noted under “General”, our mission is to be the lead community bank within the communities we serve, while our vision is to optimize the long-term return to our customers and communities, employees and shareholders (the “3 Circles”), guided by our five core values. Meaningful execution on the mission and vision comes from all employees embodying the core values and the 3 Circles in their decision-making and daily actions for their customers and communities.

Attracting and retaining talented team members is key to Nicolet’s ability to execute on its mission and vision; thus, we take a comprehensive approach to support the financial, physical, and emotional well-being of our team members. Our financial well-being includes a company match 401(k) plan, health savings accounts, Employee Stock Purchase Plan, education and adoption assistance programs. The physical well-being of our team members is supported by the Company’s health, dental, vision, life and various other insurance options, as well as a wellness program that helps employees lose weight to lead a healthy and balanced lifestyle. For emotional well-being, we provide paid time off, an employee assistance program, and fitness membership discounts.

We support the communities we serve through our employees’ dedication to giving back and we regularly sponsor local community events so that our employees can better integrate themselves in our communities. We believe that our employees’ well-being and personal and professional development is fostered by our outreach to the communities we serve. We support and encourage our employees’ desire for active community involvement by promoting causes of interest to employees, flexible schedules to support volunteerism, and giving of money to charities, community events or community organizations also served by employee volunteers. This includes Nicolet National Foundation, Inc., a public charity formed near our opening as a way for employees to give back, with 100% of the monies given by employees going directly back into our communities based on recommendations from our employees, and a 100% match of employee giving by the Bank to further support our community giving over time.

Nicolet believes that employee diversity is directly linked to organizational performance and is committed to diversity and inclusion, including women, minorities, age, individuals with disabilities, culture, and life experiences, among others. In support of this, all employees complete annual diversity training, managers complete additional diversity training in management foundation training, and we expect our employees to be active in promoting diversity within the Company and communities we serve. Nicolet also analyzes pay practices to seek to ensure we are fair and equitable among our diverse employee population. Our workforce at year end 2021 was 76% women, 24% men, and 42% of all officer titles were women.

Market Area and Competition

The Bank is a full-service community bank, providing services ranging from commercial, agricultural, and consumer banking to wealth management and retirement plan services. Nicolet operates in Northeast and Central Wisconsin, Northern Michigan and the upper peninsula of Michigan. Nicolet markets its services to owner-managed companies, the individual owners of these businesses, and other residents of its market area, which at December 31, 2021 is through 52 branches located principally within the geographic area of its branch locations.

The financial services industry is highly competitive. Nicolet competes for loans, deposits and wealth management or financial services in all its principal markets. Nicolet competes directly with other bank and nonbank institutions located within our markets (some that may have an established customer base or name recognition), internet-based banks, out-of-market banks that advertise or otherwise serve its markets, money market and other mutual funds, brokerage houses, mortgage companies, insurance companies or other commercial entities that offer financial services products. Competition involves efforts to retain current or procure new customers, obtain new loans and deposits, increase the scope and type of products or services offered, and offer competitive interest rates paid on deposits or earned on loans, as well as to deliver other aspects of banking competitively. Many of Nicolet’s competitors may enjoy competitive advantages, including greater financial resources, fewer regulatory requirements, broader geographic presence, more accessible branches or more advanced technology to deliver products or services, more favorable pricing alternatives and lower origination or operating costs.

We believe our competitive pricing, personalized service and community engagement enable us to effectively compete in our markets. Nicolet employs seasoned banking and wealth management professionals with experience in its market areas and who are active in their communities. We believe our emphasis on meeting customer needs in a relationship-focused manner, combined with local decision making on extensions of credit, distinguishes Nicolet from its competitors, particularly in the case of large financial institutions. Nicolet believes it further distinguishes itself by providing a range of products and services characteristic of a large financial institution while providing the personalized service and convenience characteristic of a local, community bank.

Supervision and Regulation

We are extensively regulated, supervised and examined under federal and state law. Generally, these laws and regulations are intended to protect our Bank’s depositors, the FDIC’s Deposit Insurance Fund and the broader banking system, and not our shareholders. These laws and regulations cover all aspects of our business, including lending and collection practices, treatment of our customers, safeguarding deposits, customer privacy and information security, capital structure, liquidity, dividends and other capital distributions, and transactions with affiliates. Such laws and regulations directly and indirectly affect key drivers of our profitability, including, for example, capital and liquidity, product offerings, risk management and costs of compliance.

Set forth below is an explanation of the major pieces of legislation and regulation affecting the banking industry and how that legislation and regulation affects Nicolet’s business. The following summary is qualified by reference to the statutory and regulatory provisions discussed. Changes in applicable laws or regulations may have a material effect on the business and prospects of Nicolet or the Bank, and legislative changes and the policies of various regulatory authorities may significantly affect their operations. We cannot predict the effect that fiscal or monetary policies, or new federal or state legislation or regulation may have on the future business and earnings of Nicolet or the Bank.

Regulation of Nicolet

Because Nicolet owns all of the capital stock of the Bank, it is a bank holding company under the federal Bank Holding Company Act of 1956, as amended (the “Bank Holding Company Act”). As a result, Nicolet is primarily subject to the supervision, examination, and reporting requirements of the Bank Holding Company Act and the regulations of the Board of Governors of the Federal Reserve System (the “Federal Reserve”). As a bank holding company located in Wisconsin, the Wisconsin Department of Financial Institutions (the “WDFI”) also regulates and monitors all significant aspects of its operations.

Acquisitions of Banks. The Bank Holding Company Act requires every bank holding company to obtain the prior approval of the Federal Reserve before:

•acquiring direct or indirect ownership or control of any voting shares of any bank if, after the acquisition, the bank holding company will directly or indirectly own or control more than 5% of the bank’s voting shares;

•acquiring all or substantially all of the assets of any bank; or

•merging or consolidating with any other bank holding company.

Additionally, the Bank Holding Company Act provides that the Federal Reserve may not approve any of these transactions if it would result in or tend to create a monopoly, substantially lessen competition, or otherwise function as a restraint of trade, unless the anti-competitive effects of the proposed transaction are clearly outweighed by the public interest in meeting the convenience and needs of the community to be served. The Federal Reserve is also required to consider the financial and managerial resources and future prospects of the bank holding companies and banks involved in the transaction and the convenience and needs of the

community to be served. The Federal Reserve’s consideration of financial resources generally focuses on capital adequacy, which is discussed below.

On July 9, 2021, President Biden issued an Executive Order on Promoting Competition in the American Economy. Among other initiatives, the Executive Order encouraged the federal banking agencies to review their current merger oversight practices under the Bank Holding Company Act and the Bank Merger Act and adopt a plan for revitalization of such practices. There are many steps that must be taken by the agencies before any formal changes to the framework for evaluating bank mergers can be finalized and the prospects for such action are uncertain at this time; however, the adoption of more expansive or prescriptive standards may have an impact on our acquisition activities.

Change in Control. Two statutes, the Bank Holding Company Act and the Change in Bank Control Act, together with regulations promulgated under them, require some form of regulatory review before any company may acquire “control” of a bank or a bank holding company. Under the Bank Holding Company Act, control is deemed to exist if a company acquires 25% or more of any class of voting securities of a bank holding company; controls the election of a majority of the members of the board of directors; or exercises a controlling influence over the management or policies of a bank or bank holding company. On January 30, 2020, the Federal Reserve issued a final rule (which became effective September 30, 2020) that clarified and codified the Federal Reserve’s standards for determining whether one company has control over another. The final rule established four categories of tiered presumptions of noncontrol that are based on the percentage of voting shares held by the investor (less than 5%, 5-9.9%, 10-14.9% and 15-24.9%) and the presence of other indicia of control. As the percentage of ownership increases, fewer indicia of control are permitted without falling outside of the presumption of noncontrol. These indicia of control include nonvoting equity ownership, director representation, management interlocks, business relationship and restrictive contractual covenants. Under the final rule, investors can hold up to 24.9% of the voting securities and up to 33% of the total equity of a company without necessarily having a controlling influence.

Under the Change in Bank Control Act, a person or company is required to file a notice with the Federal Reserve if it will, as a result of the transaction, own or control 10% or more of any class of voting securities or direct the management or policies of a bank or bank holding company and either if the bank or bank holding company has registered securities or if the acquirer would be the largest holder of that class of voting securities after the acquisition. For a change in control at the holding company level, both the Federal Reserve and the subsidiary bank’s primary federal regulator must approve the change in control; at the bank level, only the bank’s primary federal regulator is involved. Transactions subject to the Bank Holding Company Act are exempt from Change in Bank Control Act requirements.

Permitted Activities. The Bank Holding Company Act has generally prohibited a bank holding company from engaging in activities other than banking or managing or controlling banks or other permissible subsidiaries and from acquiring or retaining direct or indirect control of any company engaged in any activities other than those determined by the Federal Reserve to be closely related to banking or managing or controlling banks as to be a proper incident thereto. Provisions of the Gramm-Leach-Bliley Act have expanded the permissible activities of a bank holding company that qualifies as a financial holding company to engage in activities that are financial in nature or incidental or complementary to financial activities. Those activities include, among other activities, certain insurance, advisory and security activities.

Nicolet meets the qualification standards applicable to financial holding companies, and elected to become a financial holding company in 2008. In order to remain a financial holding company, Nicolet must continue to be considered well managed and well capitalized by the Federal Reserve, and the Bank must continue to be considered well managed and well capitalized by the Office of the Comptroller of the Currency (the “OCC”) and have at least a “satisfactory” rating under the Community Reinvestment Act.

Support of Subsidiary Institutions. Under Federal Reserve policy and the Dodd-Frank Act, Nicolet is expected to act as a source of financial strength for the Bank and to commit resources to support the Bank. This support may be required at times when, without this Federal Reserve policy or the related rules, Nicolet might not be inclined to provide it.

In addition, any capital loans made by Nicolet to the Bank will be repaid only after the Bank’s deposits and various other obligations are repaid in full.

Capital Adequacy. Nicolet is subject to capital requirements applied on a consolidated basis, which are substantially similar to those required of the Bank, which are summarized under “Regulation of the Bank” below.

Dividend Restrictions. Under Federal Reserve policies, bank holding companies may pay cash dividends on common stock only out of income available over the past year if prospective earnings retention is consistent with the organization’s expected future needs and financial condition and if the organization is not in danger of not meeting its minimum regulatory capital requirements. Federal Reserve policy also provides that bank holding companies should not maintain a level of cash dividends that undermines the bank holding company’s ability to serve as a source of strength to its banking subsidiaries. Under Federal Reserve policy, bank holding companies are expected to inform the Federal Reserve reasonably in advance of declaring or paying a dividend that exceeds

earnings for the period (e.g., quarter) for which the dividend is being paid or that could result in a material adverse change to the organization’s capital structure.

Stock Buybacks and Other Capital Redemptions. Under Federal Reserve policies and regulations, bank holding companies must seek regulatory approval prior to any redemption that would reduce the bank holding company’s consolidated net worth by 10% or more, prior to the redemption of most instruments included in Tier 1 or Tier 2 capital with features permitting redemption at the option of the issuing bank holding company, or prior to the redemption of equity or other capital instruments included in Tier 1 or Tier 2 capital prior to stated maturity, if such redemption could have a material effect on the level or composition of the organization’s capital base. Bank holding companies are also expected to inform the Federal Reserve reasonably in advance of a redemption or repurchase of common stock if such buyback results in a net reduction of the company’s outstanding amount of common stock below the amount outstanding at the beginning of the fiscal quarter.

Regulation of the Bank

Because the Bank is chartered as a national bank, it is primarily subject to the supervision, examination, and reporting requirements of the National Bank Act and the regulations of the OCC. The OCC regularly examines the Bank’s operations and has the authority to approve or disapprove mergers, the establishment of branches and similar corporate actions. The OCC also has the power to prevent the continuance or development of unsafe or unsound banking practices or other violations of law. Because the Bank’s deposits are insured by the FDIC to the maximum extent provided by law, it is also subject to certain FDIC regulations and the FDIC also has examination authority and back-up enforcement power over the Bank. The Bank is also subject to numerous state and federal statutes and regulations that affect Nicolet, its business, activities, and operations.

Branching. National banks are required by the National Bank Act to adhere to branching laws applicable to state banks in the states in which they are located. Under Wisconsin law and the Dodd-Frank Act, and with the prior approval of the OCC, the Bank may open branch offices within or outside of Wisconsin, provided that a state bank chartered by the state in which the branch is to be located would also be permitted to establish a branch. In addition, with prior regulatory approval, the Bank may acquire branches of existing banks located in Wisconsin or other states.

Capital Adequacy. Banks and bank holding companies, as regulated institutions, are required to maintain minimum levels of capital. The Federal Reserve and the OCC have adopted minimum risk-based capital requirements (Tier 1 capital, common equity Tier 1 capital (“CET1”) and total capital) and leverage capital requirements, as well as guidelines that define components of the calculation of capital and the level of risk associated with various types of assets. Financial institutions are expected to maintain a level of capital commensurate with the risk profile assigned to their assets in accordance with the guidelines.

In addition to the minimum risk-based capital and leverage ratios, banking organizations must maintain a “capital conservation buffer” consisting of CET1 in an amount equal to 2.5% of risk-weighted assets in order to avoid restrictions on their ability to make capital distributions and to pay certain discretionary bonus payments to executive officers. In order to avoid those restrictions, the capital conservation buffer effectively increases the minimum well-capitalized CET1 capital, Tier 1 capital, and total capital ratios for U.S. banking organizations to 7.0%, 8.5%, and 10.5%, respectively. Banking organizations with capital levels that fall within the buffer will be required to limit dividends, share repurchases or redemptions (unless replaced within the same calendar quarter by capital instruments of equal or higher quality), and discretionary bonus payments. The following table presents the risk-based and leverage capital requirements applicable to the Bank:

	Adequately Capitalized<br>Requirement		Well-Capitalized<br>Requirement		Well-Capitalized<br>with Buffer
Leverage	4.0	%	5.0	%	5.0	%
CET1	4.5	%	6.5	%	7.0	%
Tier 1	6.0	%	8.0	%	8.5	%
Total Capital	8.0	%	10.0	%	10.5	%

Although capital instruments such as trust preferred securities and cumulative preferred shares are excluded from Tier 1 capital for certain larger banking organizations, Nicolet’s trust preferred securities are grandfathered as Tier 1 capital (provided they do not exceed 25% of Tier 1 capital) so long as Nicolet has less than $15 billion in total assets.

The capital rules require that goodwill and other intangible assets (other than mortgage servicing assets), net of associated deferred tax liabilities (“DTLs”), be deducted from CET1 capital. Additionally, deferred tax assets (“DTAs”) that arise from net operating loss and tax credit carryforwards, net of associated DTLs and valuation allowances, are fully deducted from CET1 capital. However, DTAs arising from temporary differences that could not be realized through net operating loss carrybacks, along with mortgage servicing assets and “significant” (defined as greater than 10% of the issued and outstanding common stock of the unconsolidated

financial institution) investments in the common stock of unconsolidated “financial institutions” are partially includible in CET1 capital, subject to deductions defined in the rules.

The OCC also considers interest rate risk (arising when the interest rate sensitivity of the Bank’s assets does not match the sensitivity of its liabilities or its off-balance sheet position) in the evaluation of the bank’s capital adequacy. Banks with excessive interest rate risk exposure are required to hold additional amounts of capital against their exposure to losses resulting from that risk. Through the risk-weighting of assets, the regulators also require banks to incorporate market risk components into their risk-based capital. Under these market risk requirements, capital is allocated to support the amount of market risk related to a bank’s lending and trading activities.

The Bank’s capital categories are determined solely for the purpose of applying the “prompt corrective action” rules described below and they are not necessarily an accurate representation of its overall financial condition or prospects for other purposes. Failure to meet capital guidelines could subject a bank or bank holding company to a variety of enforcement remedies, including issuance of a capital directive, the termination of deposit insurance by the FDIC, a prohibition on accepting brokered deposits, and certain other restrictions on its business. See “Prompt Corrective Action” below.

Prompt Corrective Action. The Federal Deposit Insurance Corporation Improvement Act of 1991 (“FDICIA”) establishes a system of prompt corrective action to resolve the problems of undercapitalized financial institutions. Under this system, the federal banking regulators have established five capital categories: well-capitalized, adequately capitalized, undercapitalized, significantly undercapitalized, and critically undercapitalized, in which all institutions are placed. The federal banking agencies have also specified by regulation the relevant capital levels for each category.

A “well-capitalized” bank is one that is not required to meet and maintain a specific capital level for any capital measure pursuant to any written agreement, order, capital directive, or prompt corrective action directive, and has a total risk-based capital ratio of at least 10%, a Tier 1 risk-based capital ratio of at least 8%, a CET1 capital ratio of at least 6.5%, and a Tier 1 leverage ratio of at least 5%. Generally, a classification as well-capitalized will place a bank outside of the regulatory zone for purposes of prompt corrective action. However, a well-capitalized bank may be reclassified as “adequately capitalized” based on criteria other than capital, if the federal regulator determines that a bank is in an unsafe or unsound condition, or is engaged in unsafe or unsound practices, which requires certain remedial action.

As of December 31, 2021, the Bank satisfied the requirements of “well-capitalized” under the regulatory framework for prompt corrective action. See Note 17, “Regulatory Capital Requirements,” in the Notes to Consolidated Financial Statements, under Part II, Item 8, for regulatory capital ratios of Nicolet and the Bank.

As a bank’s capital position deteriorates, federal banking regulators are required to take various mandatory supervisory actions and are authorized to take other discretionary actions with respect to institutions in the three undercapitalized categories: undercapitalized, significantly undercapitalized, and critically undercapitalized. The severity of the action depends upon the capital category in which the institution is placed. Generally, subject to a narrow exception, the banking regulator must appoint a receiver or conservator for an institution that is critically undercapitalized.

CECL. The Financial Accounting Standards Board (“FASB”) adopted a new credit loss accounting standard applicable to all banks, savings associations, credit unions, and financial holding companies, regardless of size. This standard became effective for the Bank for our fiscal year beginning on January 1, 2020. The final rule allows for an optional three-year phase in of the day-one adverse effects on a bank’s regulatory capital. This Current Expected Credit Losses (“CECL”) standard requires financial institutions to determine periodic estimates of lifetime expected credit losses on loans, and recognize the expected credit losses as an allowance for credit losses.

The CECL rules changed the prior “incurred losses” method of providing Allowances for Credit Losses (“ACL”), which has required us to increase our allowance, and to greatly increase the data we need to collect and review to determine the appropriate level of the ACL. Under CECL, the allowance for credit losses is an estimate of the expected credit losses on financial assets measured at amortized cost, which is measured using relevant information about past events, including historical credit loss experience on financial assets with similar risk characteristics, current conditions, and reasonable and supportable forecasts that affect the collectability of the remaining cash flows over the contractual term of the financial assets. CECL requires an allowance to be created upon the origination or acquisition of a financial asset measured at amortized cost, which may significantly impact the cost of M&A activity in the future. Any increase in our ACL, or expenses incurred to determine the appropriate level of the ACL, may have a material adverse effect on our financial condition and results of operations. For additional discussion of CECL, see section “Allowance for Credit Losses-Loans” within Note 1 “Nature of Business and Significant Accounting Policies,” of the Notes to Consolidated Financial Statements under Part II, Item 8.

FDIC Insurance Assessments. The Bank’s deposits are insured by the Deposit Insurance Fund of the FDIC up to $250,000, the maximum amount permitted by law. The FDIC uses the Deposit Insurance Fund to protect against the loss of insured deposits if an

FDIC-insured bank or savings association fails. The Bank is thus subject to FDIC deposit premium assessments. The cost of premium assessments are impacted by, among other things, a bank’s capital category under the prompt corrective action system.

Commercial Real Estate Lending. The federal banking regulators have issued the following guidance to help identify institutions that are potentially exposed to significant commercial real estate lending risk and may warrant greater supervisory scrutiny:

•total reported loans for construction, land development and other land represent 100% or more of the institution’s total capital, or

•total commercial real estate loans represent 300% or more of the institution’s total capital, and the outstanding balance of the institution’s commercial real estate loan portfolio has increased by 50% or more.

At December 31, 2021 the Bank’s commercial real estate lending levels are below the guidance levels noted above.

Enforcement Powers. The Financial Institution Reform Recovery and Enforcement Act (“FIRREA”) expanded and increased civil and criminal penalties available for use by the federal regulatory agencies against depository institutions and certain “institution-affiliated parties.” Institution-affiliated parties primarily include management, employees, and agents of a financial institution, as well as independent contractors and consultants such as attorneys and accountants and others who participate in the conduct of the financial institution’s affairs. These practices can include the failure of an institution to timely file required reports or the filing of false or misleading information or the submission of inaccurate reports. Civil penalties may be over $1.9 million per day for such violations. Criminal penalties for some financial institution crimes have been increased to 20 years.

Community Reinvestment Act. The Community Reinvestment Act (“CRA”) requires that, in connection with examinations of financial institutions within their respective jurisdictions, the federal banking agencies evaluate the record of each financial institution in meeting the credit needs of its local community, including low- and moderate-income neighborhoods. These facts are also considered in evaluating mergers, acquisitions, and applications to open a branch or facility. Failure to adequately meet these criteria could impose additional requirements and limitations on the Bank. Additionally, the Bank must publicly disclose the terms of various Community Reinvestment Act-related agreements. The Bank received an “outstanding” CRA rating in its most recent evaluation.

In December 2019, the OCC and the FDIC issued a notice of proposed rulemaking intended to (i) clarify which activities qualify for CRA credit; (ii) update where activities count for CRA credit; (iii) create a more transparent and objective method for measuring CRA performance; and (iv) provide for more transparent, consistent, and timely CRA-related data collection, recordkeeping, and reporting. However, the Federal Reserve has not joined the proposed rulemaking. In May 2020, the OCC issued its final CRA rule, which was later rescinded in December 2021. On the same day that the OCC announced its plans to rescind the June 2020 rule, the OCC, FDIC, and Federal Reserve announced that they are working together to “strengthen and modernize the rules implementing the CRA.” The effects on the Bank of any potential change to the CRA rules will depend on the final form of any federal rulemaking and cannot be predicted at this time. Management will continue to evaluate any changes to the CRA’s regulations and their impact to the Bank.

Payment of Dividends. Statutory and regulatory limitations apply to the Bank’s payment of dividends to the Parent Company. If, in the opinion of the OCC, the Bank were engaged in or about to engage in an unsafe or unsound practice, the OCC could require that the Bank stop or refrain from engaging in the practice. The federal banking agencies have indicated that paying dividends that deplete a depository institution’s capital base to an inadequate level would be an unsafe and unsound banking practice.

The Bank is required by federal law to obtain prior approval of the OCC for payments of dividends if the total of all dividends declared by the Bank in any year will exceed (1) the total of the Bank’s net profits for that year, plus (2) the Bank’s retained net profits of the preceding two years. The payment of dividends may also be affected by other factors, such as the requirement to maintain adequate capital above regulatory guidelines or any conditions or restrictions that may be imposed by regulatory authorities.

Transactions with Affiliates and Insiders. The Bank is subject to the provisions of Regulation W promulgated by the Federal Reserve, which implements Sections 23A and 23B of the Federal Reserve Act. Regulation W places limits and conditions on the amount of loans or extensions of credit to, investments in, or certain other transactions with, affiliates and on the amount of advances to third parties collateralized by the securities or obligations of affiliates. Regulation W also prohibits, among other things, an institution from engaging in certain transactions with certain affiliates unless the transactions are on terms substantially the same, or at least as favorable to such institution or its subsidiaries, as those prevailing at the time for comparable transactions with nonaffiliated companies. Federal law also places restrictions on the Bank’s ability to extend credit to its executive officers, directors, principal shareholders and their related interests. These extensions of credit must be made on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable transactions with unrelated third parties; and must not involve more than the normal risk of repayment or present other unfavorable features.

USA PATRIOT Act. The Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001 (the “USA PATRIOT Act") requires each financial institution to: (i) establish an anti-money laundering program; and (ii) establish due diligence policies, procedures and controls with respect to its private and correspondent banking accounts involving foreign individuals and certain foreign banks. In addition, the USA PATRIOT Act encourages cooperation among financial institutions, regulatory authorities and law enforcement authorities with respect to individuals, entities and organizations engaged in, or reasonably suspected of engaging in, terrorist acts or money laundering activities.

Customer Protection. The Bank is also subject to consumer laws and regulations intended to protect consumers in transactions with depository institutions, as well as other laws or regulations affecting customers of financial institutions generally. While the list set forth herein is not exhaustive, these laws and regulations include the Truth in Lending Act, the Truth in Savings Act, the Electronic Funds Transfer Act, the Expedited Funds Availability Act, the Equal Credit Opportunity Act, the Fair Housing Act, the Real Estate Settlement and Procedures Act, the Fair Credit Reporting Act and the Federal Trade Commission Act, among others. These laws and regulations mandate certain disclosure requirements and regulate the manner in which financial institutions must deal with customers when taking deposits or making loans to such customers.

Financial Privacy and Cybersecurity. Under privacy protection provisions of the Gramm-Leach-Bliley Act of 1999 and related regulations, we are limited in our ability to disclose non-public information about consumers to nonaffiliated third parties. These limitations require disclosure of privacy policies to consumers and, in some circumstances, allow consumers to prevent disclosure of certain personal information to a nonaffiliated third party. Federal banking agencies have adopted guidelines for establishing information security standards and cybersecurity programs for implementing safeguards under the supervision of the board of directors. These guidelines, along with related regulatory materials, increasingly focus on risk management and processes related to information technology and the use of third parties in the provision of financial services.

Consumers must be notified in the event of a data breach under applicable state laws. Multiple states and Congress are considering laws or regulations which could create new individual privacy rights and impose increased obligations on companies handling personal data. For example, on November 18, 2021, the federal financial regulatory agencies published a final rule that will impose upon banking organizations and their service providers new notification requirements for significant cybersecurity incidents. Specifically, the final rule requires banking organizations to notify their primary federal regulator as soon as possible and no later than 36 hours after the discovery of a “computer-security incident” that rises to the level of a “notification incident” within the meaning attributed to those terms by the final rule. Banks’ service providers are required under the final rule to notify any affected bank to or on behalf of which the service provider provides services “as soon as possible” after determining that it has experienced an incident that materially disrupts or degrades, or is reasonably likely to materially disrupt or degrade, covered services provided to such bank for as much as four hours. The final rule will take effect on April 1, 2022 and banks and their service providers must be in compliance with the requirements of the rule by May 1, 2022.

Consumer Financial Protection Bureau. The Dodd-Frank Act centralized responsibility for consumer financial protection including implementing, examining and enforcing compliance with federal consumer financial laws with the Consumer Financial Protection Bureau (the “CFPB”). Depository institutions with less than $10 billion in assets, such as the Bank, are subject to rules promulgated by the CFPB but will continue to be examined and supervised by federal banking regulators for consumer compliance purposes.

UDAP and UDAAP. Bank regulatory agencies have increasingly used a general consumer protection statute to address “unethical” or otherwise “bad” business practices that may not necessarily fall directly under the purview of a specific banking or consumer finance law. The law of choice for enforcement against such business practices has been Section 5 of the Federal Trade Commission Act—the primary federal law that prohibits “unfair or deceptive acts or practices” and unfair methods of competition in or affecting commerce (“UDAP” or “FTC Act”). “Unjustified consumer injury” is the principal focus of the FTC Act. Prior to the Dodd-Frank Act, there was little formal guidance to provide insight to the parameters for compliance with the UDAP law. However, the UDAP provisions have been expanded under the Dodd-Frank Act to apply to “unfair, deceptive or abusive acts or practices” (“UDAAP”). The CFPB has brought a variety of enforcement actions for violations of UDAAP provisions and CFPB guidance continues to evolve.

ITEM 1A. RISK FACTORS

An investment in our common stock involves risks. If any of the following risks, or other risks which have not been identified or which we may believe are immaterial or unlikely, actually occurs, our business, financial condition and results of operations could be harmed. In such a case, the trading price of our common stock could decline, and you could lose all or part of your investment. The risks discussed below also include forward-looking statements, and our actual results may differ substantially from those discussed in these forward-looking statements.

Growth and Strategic Risks

Nicolet may not be able to sustain its historical rate of growth, or may encounter issues associated with its growth, either of which could adversely affect our financial condition, results of operations, and share price.

We have grown over the past several years and intend to continue to pursue a significant growth strategy for our business. Our prospects must be considered in light of the risks, expenses and difficulties frequently encountered by companies in significant growth stages of development. We may not be able to further expand our market presence in existing markets or to enter new markets successfully, nor can we guarantee that any such expansion would not adversely affect our results of operations. Failure to manage growth effectively could have a material adverse effect on the business, future prospects, financial condition or results of our operations, and could adversely affect our ability to successfully implement business strategies. Also, if such growth occurs more slowly than anticipated or declines, our operating results could be materially adversely affected.

Our ability to grow successfully will depend on a variety of factors including the continued availability of desirable business opportunities, the competitive responses from other financial institutions in our market areas and the ability to manage our growth. While we believe we have the management resources and internal systems in place to manage future growth successfully, there can be no assurance that growth opportunities will be available or that any growth will be managed successfully. In addition, our recent growth may distort some of our historical financial ratios and statistics.

As part of our growth strategy, we regularly evaluate merger and acquisition opportunities and conduct due diligence activities related to possible transactions with other financial institutions and financial services companies. As a result, negotiations may take place and future mergers or acquisitions involving cash, debt, or equity securities may occur at any time. We seek merger or acquisition partners that are culturally similar, have experienced management, and possess either significant market presence or have potential for improved profitability through financial management, economies of scale, or expanded services. However, it is possible that some acquisitions might not close as a result of failure to meet closing conditions or the market could negatively affect the banking environment so much that an acquisition that may have, at one time, been beneficial to both institutions is now no longer prudent.

Acquiring other banks, businesses, or branches involves potential adverse impact to our financial results and various other risks commonly associated with acquisitions, including, among other things, difficulty in estimating the value of the target company, payment of a premium over book and market values that may dilute our tangible book value and earnings per share in the short and long term, potential exposure to unknown or contingent liabilities of the target company, exposure to potential asset quality issues of the target company, potential volatility in reported income as goodwill impairment losses could occur irregularly and in varying amounts, difficulty and expense of integrating the operations and personnel of the target company, inability to realize the expected revenue increases, cost savings, increases in geographic or product presence, and / or other projected benefits, potential disruption to our business, potential diversion of our management’s time and attention, and the possible loss of key employees and customers of the target company.

Future acquisitions may be delayed, impeded, or prohibited due to regulatory issues.

Our future acquisitions, particularly those of financial institutions, are subject to approval by a variety of federal and state regulatory agencies. Regulatory approvals could be delayed, impeded, restrictively conditioned or denied due to existing or new regulatory issues we have, or may have, with regulatory agencies, including, without limitation, issues related to anti-money laundering/Bank Secrecy Act compliance, fair lending laws, fair housing laws, consumer protection laws, unfair, deceptive, or abusive acts or practices regulations, Community Reinvestment Act issues, and other similar laws and regulations. We may fail to pursue, evaluate or complete strategic and competitively significant acquisition opportunities as a result of our inability, or perceived or anticipated inability, to obtain regulatory approvals in a timely manner, under reasonable conditions or at all. Difficulties associated with potential acquisitions that may result from these factors could have a material adverse effect on our business, and, in turn, our financial condition and results of operations.

Moreover, in July 2021, President Biden issued an Executive Order on Promoting Competition in the American Economy which encouraged the federal banking agencies to review their current merger oversight practices. The Executive Order has received significant public support from members of Congress as well as a majority of the board members of the FDIC. In addition, the Director of the CFPB has publicly sought a greater role for the CFPB in the evaluation of proposed bank mergers. Any enhanced

regulatory scrutiny of bank mergers and acquisitions and revision of the framework for merger application review may adversely affect the marketplace for such transactions, could result in our acquisitions in future periods being delayed, impeded or restricted in certain respects and result in new rules that possibly limit the size of financial institutions we may be able to acquire in the future and alter the terms for such transactions.

COVID-19 and Economic-Related Risks

The ongoing COVID-19 pandemic could have an adverse impact on our financial performance and results of operations.

As the COVID-19 pandemic has evolved from its emergence in early 2020, so has its impact. Many states have re-instituted, or strongly encouraged, varying levels of quarantines and restrictions on travel and in some cases have at times limited operations of certain businesses and taken other restrictive measures designed to help slow the spread of COVID-19 and its variants. Governments and businesses have also instituted vaccine mandates and testing requirements for employees. While vaccine availability and uptake has increased, the longer-term macro-economic effects on global supply chains, inflation, labor shortages and wage increases continue to impact many industries, including the collateral underlying certain of our loans. Moreover, with the potential for new strains of COVID-19 to emerge, governments and businesses may re-impose aggressive measures to help slow its spread in the future. For this reason, among others, as the COVID-19 pandemic continues, the potential impacts are uncertain and difficult to assess.

Although financial markets have largely rebounded from the significant declines that occurred earlier in the pandemic and global economic conditions showed signs of improvement during the second half of 2020 and throughout 2021, many of the circumstances that arose or became more pronounced after the onset of the COVID-19 pandemic persist, which may subject us to any of the following risks:

•lower loan demand and an increased risk of loan delinquencies, defaults, and foreclosures due a number of factors, including continuing supply chain issues, decreased consumer and business confidence and economic activity;

•collateral for loans, especially real estate, may decline in value, which may reduce our ability to liquidate such collateral and could cause loan losses to increase and impair our ability over the long run to maintain our targeted loan origination volume;

•volatility in financial and capital markets, interest rates, and exchange rates;

•a significant decline in the market value of our common stock, which may result in us recording a goodwill impairment charge, which could adversely affect our results of operations;

•increased demands on capital and liquidity;

•a reduction in the value of the assets that we manage or otherwise administer or service for others, affecting related fee income and demand for our services;

•heightened cybersecurity, information security, and operational risks as cybercriminals attempt to profit from the disruption resulting from the pandemic given increased online and remote activity;

•disruptions to business operations experienced by counterparties and service providers;

•increased risk of business disruption from the loss of employees due to their inability to work effectively because of illness, quarantines, government actions, or other effects of the COVID-19 pandemic (including the increase in employee resignations currently taking place throughout the United States in connection with the COVID-19 pandemic, which is commonly referred to as the “great resignation”); and

•decreased demands for our products and services.

We have also experienced and may experience other negative impacts to our business as a result of the pandemic that could exacerbate other risks discussed in this “Risk Factors” section. The ongoing fluidity of this situation precludes any prediction as to the ultimate adverse impact of COVID-19 on economic and market conditions, and, as a result, presents material uncertainty and risk with respect to us.

As a community bank, Nicolet’s success depends upon local and regional economic conditions and has different lending risks than larger banks.

We provide services to our local communities. Our ability to diversify economic risks is limited by our own local markets and economies. We lend primarily to individuals and small- to medium-sized businesses, which may expose us to greater lending risks than those of banks lending to larger, better-capitalized businesses with longer operating histories.

We manage our credit exposure through careful monitoring of loan applicants and loan concentrations in particular industries, and through loan approval and review procedures. We have established an evaluation process designed to determine the appropriateness of our allowance for credit losses. While this evaluation process uses historical and other objective information, the classification of loans and the establishment of credit losses is an estimate based on experience, judgment and expectations regarding borrowers and

economic conditions, as well as regulator judgments. We can make no assurance that our credit loss reserves will be sufficient to absorb future credit losses or prevent a material adverse effect on our business, profitability or financial condition.

The core industries in our market area are manufacturing, wholesaling, paper, packaging, food production and processing, agriculture, forest products, hospitality, retail, service, and businesses supporting the general building industry. The area has a broad range of diversified equipment manufacturing services related to these core industries and others. The residential and commercial real estate markets throughout these areas depend primarily on the strength of these core industries. A material decline in any of these sectors will affect the communities we serve and could negatively impact our financial results and have a negative impact on profitability.

If the communities in which we operate do not grow or if the prevailing economic conditions locally or nationally are less favorable than we have assumed, this may result in deterioration in the credit quality of our borrowers and the demand for our products and services, an increase in the number of loan delinquencies, defaults and charge-offs, foreclosures, additional provision for credit losses, adverse asset values of the collateral securing our loans, and an overall material adverse effect on the quality of our loan portfolio, and a reduction in assets under management or administration. These negative effects may cause us to incur losses and may adversely affect our capital, liquidity and financial condition.

Credit and Interest Rate Risks

Nicolet may experience increased delinquencies and credit losses, which could have a material adverse effect on our capital, financial condition, results of operations, and share price.

Our success depends to a significant extent upon the quality of our assets, particularly loans. In originating loans, there is a substantial likelihood that we will experience credit losses. The risk of loss will vary with, among other things, general economic conditions, the type of loan, the creditworthiness of the borrower over the term of the loan, and, in the case of a collateralized loan, the quality of the collateral for the loan.

Our loan customers may not repay their loans according to the terms of these loans, and the collateral securing the payment of these loans may be insufficient to assure repayment. As a result, we may experience significant credit losses, which could have a material adverse effect on our operating results. Management makes various assumptions and judgments about the collectability of our loan portfolio, including the creditworthiness of our borrowers and the value of the real estate and other assets serving as collateral for the repayment of many of our loans. We maintain an allowance for credit losses in an attempt to cover any loan losses that may occur. Determining the appropriate level of the allowance involves a high degree of subjectivity and requires management to make significant estimates using quantitative and qualitative information about our loan portfolio, including historical loss experience, volume and types of loans, trends in classification, volume and trends in delinquencies and nonaccruals, national and local economic conditions, reasonable and supportable forecasts, and other pertinent information.

If management’s assumptions are wrong, our current allowance may not be sufficient to cover future loan losses, and we may need to make adjustments to allow for different economic conditions or adverse developments in our loan portfolio. Material additions to our allowance would materially decrease net income. We expect our allowance to continue to fluctuate; however, given current and future market conditions, we can make no assurance that our allowance will be appropriate to cover future credit losses.

In addition, the market value of the real estate securing our loans as collateral could be adversely affected by the economy and unfavorable changes in economic conditions in our market areas. As of December 31, 2021, approximately 39% of our loans were secured by commercial-based real estate, 9% of loans were secured by agriculture-based real estate, and 19% of our loans were secured by residential real estate. Any sustained period of increased payment delinquencies, foreclosures, or losses caused by adverse market and economic conditions, including a downturn in the real estate market, in our markets could adversely affect the value of our assets, results of operations, and financial condition.

Nicolet’s profitability is sensitive to changes in the interest rate environment.

As a financial institution, our earnings significantly depend on net interest income, which is the difference between the interest income that we earn on interest-earning assets, such as investment securities and loans, and the interest expense that we pay on interest-bearing liabilities, such as deposits and borrowings. Therefore, any change in general market interest rates, including changes in federal fiscal and monetary policies, affects us more than non-financial institutions and can have a significant effect on our net interest income and total income. Our assets and liabilities may react differently to changes in overall market rates or conditions because there may be mismatches between the repricing or maturity characteristics of the assets and liabilities. As a result, an increase or decrease in market interest rates could have material adverse effects on our net interest margin and results of operations.

In addition, we cannot predict whether interest rates will continue to remain at present levels, or the timing of any anticipated changes. Changes in interest rates may cause significant changes, up or down, in our net interest income. If the interest rates paid on deposits and borrowings increase at a faster rate than the interest rates received on loans and investment securities, our net interest

income, and therefore earnings, could be adversely affected. Earnings also could be adversely affected if the interest rates received on loans and investment securities fall more quickly than the interest rates paid on deposits and borrowings. In addition, if there is a substantial increase in interest rates, our investment portfolio is at risk of experiencing price declines that may negatively impact our total capital position through changes in other comprehensive income. Any significant increase in prevailing interest rates could also adversely affect our mortgage banking business because higher interest rates could cause customers to request fewer refinancing and purchase money mortgage originations.

Nicolet will be required to transition from the use of the LIBOR interest rate index in the future.

We have certain loans, investment securities, subordinated notes, and junior subordinated debentures indexed to LIBOR to calculate the interest rate. The continued availability of the LIBOR index is not guaranteed as the administrators of LIBOR have announced that the publication of the most commonly used LIBOR settings will cease to be published after June 2023. We cannot predict whether and to what extent banks will continue to provide LIBOR submissions to the administrator of LIBOR or whether any additional reforms to LIBOR may be enacted. At this time, no consensus exists as to what rate or rates may become acceptable alternatives to LIBOR (with the exception of overnight repurchase agreements, which are expected to be based on the Secured Overnight Financing Rate, or SOFR). There also remains uncertainty in the LIBOR transition as new index rates and payments will differ from LIBOR, which may lead to increased volatility as well as potential changes in risk, pricing or valuation models.

The language in our LIBOR-based contracts has developed over time, as such, the timing and manner in which each contract transitions to a new index will vary on a case-by-case basis. As of December 31, 2021, we are no longer originating new LIBOR-based loan contracts, and the majority of our existing LIBOR-based loan contracts are line of credit agreements with an annual renewal. These contracts are expected to transition to 1-month term SOFR or another index at the next annual renewal date. In addition, we have sufficient fallback language in our remaining LIBOR-based loan contracts with maturities that extend past the June 2023 LIBOR cease date. With respect to our investment securities, subordinated notes, and junior subordinated debentures, we expect similar transition resolutions.

Legal, Regulatory and Compliance Risks

Nicolet is subject to extensive regulation that could limit or restrict our activities, which could have a material adverse effect on our results of operations or share price.

We operate in a highly regulated industry and are subject to examination, supervision, and comprehensive regulation by various regulatory agencies. Our compliance with these regulations, including compliance with regulatory commitments, is costly and restricts certain of our activities, including the declaration and payment of cash dividends to stockholders, mergers and acquisitions, investments, loans and interest rates charged, interest rates paid on deposits, and locations of offices. We are also subject to capitalization guidelines established by our regulators, which require us to maintain adequate capital to support our growth and operations.

The laws and regulations applicable to the banking industry have changed and are likely to continue to change, and we cannot predict the effects of these changes on our business and profitability. Some or all of the changes, including the rule-making authority granted to the CFPB, may result in greater reporting requirements, assessment fees, operational restrictions, capital requirements, and other regulatory burdens for us, and many of our competitors that are not banks or bank holding companies may remain free from such limitations. This could affect our ability to attract and retain depositors, to offer competitive products and services, and to expand our business. Because government regulation greatly affects the business and financial results of all commercial banks and bank holding companies, the cost of compliance could adversely affect our ability to operate profitably.

Congress may consider additional proposals to substantially change the financial institution regulatory system and to expand or contract the powers of banking institutions, bank holding companies and financial holding companies. Such legislation may change existing banking statutes and regulations, as well as the current operating environment significantly. If enacted, such legislation could increase or decrease the cost of doing business, limit or expand permissible activities, or affect the competitive balance among banks, savings associations, credit unions, and other financial institutions. We cannot predict whether new legislation will be enacted and, if enacted, the effect that it, or any regulations, would have on our business, financial condition, or results of operations.

We face a risk of noncompliance with the Bank Secrecy Act and other anti-money laundering statutes and regulations and corresponding enforcement proceedings.

The federal Bank Secrecy Act, the PATRIOT Act, and other laws and regulations require financial institutions, among our other duties, to institute and maintain effective anti-money laundering programs and to file suspicious activity and currency transaction reports as appropriate. The federal Financial Crimes Enforcement Network, established by the U.S. Treasury Department to administer the Bank Secrecy Act, is authorized to impose significant civil money penalties for violations of those requirements and has recently engaged in coordinated enforcement efforts with the individual federal banking regulators, as well as the U.S. Department of Justice, Drug Enforcement Administration and Internal Revenue Service. There is also increased scrutiny of

compliance with the rules enforced by the Office of Foreign Assets Control. Federal and state bank regulators also focus on compliance with Bank Secrecy Act and anti-money laundering regulations. If our policies, procedures and systems are deemed deficient or the policies, procedures and systems of the financial institutions that we have already acquired or may acquire in the future are deficient, we would be subject to liability, including fines and regulatory actions such as restrictions on our ability to pay dividends and the necessity to obtain regulatory approvals to proceed with certain aspects of our business plan, including our acquisition plans, which would negatively impact our business, financial condition and results of operations. Failure to maintain and implement adequate programs to combat money laundering and terrorist financing could also have serious reputational consequences for us.

We are subject to federal and state fair lending laws, and failure to comply with these laws could lead to material penalties.

Federal and state fair lending laws and regulations, such as the Equal Credit Opportunity Act and the Fair Housing Act, impose nondiscriminatory lending requirements on financial institutions. The Department of Justice, the CFPB and other federal and state agencies are responsible for enforcing these laws and regulations. Private parties may also have the ability to challenge an institution’s performance under fair lending laws in private class action litigation. A successful challenge to our performance under the fair lending laws and regulations could adversely impact our rating under the Community Reinvestment Act and result in a wide variety of sanctions, including the required payment of damages and civil money penalties, injunctive relief, imposition of restrictions on merger and acquisition activity and restrictions on expansion activity, which could negatively impact our reputation, business, financial condition, and results of operations.

We face risks related to the adoption of future legislation and potential changes in federal regulatory agency leadership, policies, and priorities.

With a new Congress taking office in 2021, Democrats have retained control of the U.S. House of Representatives, and have gained control of the U.S. Senate, albeit with a majority found only in the tie-breaking vote of Vice President Harris. However slim the majorities, though, the net result was a unified Democratic control of the White House and both chambers of Congress, and consequently Democrats are able to set the agenda both legislatively, in the Administration, and in the regulatory agencies that have rulemaking and supervisory authority over the financial services industry generally and the Company and the Bank specifically. Congressional committees with jurisdiction over the banking sector have pursued oversight and legislative initiatives in a variety of areas, including addressing climate-related risks, promoting diversity and equality within the banking industry and addressing other Environmental, Social, and Governance matters, improving competition in the banking sector and enhancing oversight of bank mergers and acquisitions, establishing a regulatory framework for digital assets and markets, and oversight of the COVID-19 pandemic response and economic recovery. The prospects for the enactment of major banking reform legislation are unclear at this time.

Moreover, the turnover of the presidential administration resulted in certain changes in the leadership and senior staffs of the federal banking agencies, the CFPB, CFTC, SEC, and the Treasury Department, with certain significant leadership positions yet to be filled, including the Comptroller of the Currency, the Chair of the FDIC and three vacancies among the Governors of the Federal Reserve Board, including the Vice Chair for Supervision. These changes have impacted the rulemaking, supervision, examination and enforcement priorities and policies of the agencies and likely will continue to do so over the next several years. The potential impact of any changes in agency personnel, policies and priorities on the financial services sector, including the Company and the Bank, cannot be predicted at this time. Regulations and laws may be modified at any time, and new legislation may be enacted that will affect us. Any future changes in federal and state laws and regulations, as well as the interpretation and implementation of such laws and regulations, could affect us in substantial and unpredictable ways, including those listed above or other ways that could have a material adverse effect on our business, financial condition or results of operations.

From time to time we are, or may become, involved in suits, legal proceedings, information-gatherings, investigations and proceedings by governmental and self-regulatory agencies that may lead to adverse consequences.

Many aspects of the banking business involve a substantial risk of legal liability. From time to time, we are, or may become, the subject of information-gathering requests, reviews, investigations and proceedings, and other forms of regulatory inquiry, including by bank regulatory agencies, self-regulatory agencies, the SEC and law enforcement authorities. The results of such proceedings could lead to significant civil or criminal penalties, including monetary penalties, damages, adverse judgements, settlements, fines, injunctions, restrictions on the way we conduct our business or reputational harm.

Operational Risks

Nicolet faces significant operational risk, including risk of loss related to cybersecurity breaches, due to the financial services industry’s increased reliance on technology.

We rely heavily on communications and information systems to conduct our business, and we rely on third party vendors to provide key components of these systems, including our core application processing. Any failure, interruption or breach in security of these systems could result in failures or disruptions in customer relationship management, general ledger, deposit, loan functionality and

the effective operation of other systems. We rely on third parties to compile, process or store computer systems, company data and infrastructure, and such information may be vulnerable to attack by hackers or unauthorized access. While we have policies and procedures designed to prevent or limit the effect of a failure, interruption or security breach of our information systems, there can be no assurance that any such failures, interruptions or security breaches will not occur or, if they do occur, that they will be adequately addressed. The occurrence of any failures, interruptions or security breaches of our information systems could damage our reputation, result in a loss of customer business, damage vendor relationships, subject us to additional regulatory scrutiny, or expose us to civil litigation and possible financial liability, any of which could have a material adverse effect on our financial condition and results of operations.

We do not control the actions of the third party vendors we have selected to provide key components of our business infrastructure. Any problems caused by these third parties, including as a result of their not providing us their services for any reason or their performing their services poorly, or any failure, interruption or breach in security of the services they provide, could adversely affect our ability to deliver products and services to our customers and otherwise to conduct our business. Replacing these third party vendors could also entail significant delay and expense.

Our business may be adversely affected by an increasing prevalence of fraud and other financial crimes.

As a financial institution, we are also susceptible to fraudulent activity that may be committed against us, our third party vendors, or our clients, which may result in financial losses or increased costs to us or our clients, disclosure or misuse of our information or our clients’ information, misappropriation of assets, privacy breaches against our clients, litigation, or damage to our reputation. These risks may increase in the future as we continue to increase our mobile-payment and other internet-based product offerings and expand our internal usage of web-based products and applications.

Negative publicity could damage our reputation.

Reputation risk, or the risk to our earnings and capital from negative public opinion, is inherent in our business. Negative public opinion could adversely affect our ability to keep and attract customers and expose us to adverse legal and regulatory consequences. Negative public opinion could result from our actual or alleged conduct in any number of activities, including lending or foreclosure practices, corporate governance, regulatory compliance, mergers and acquisitions, and disclosure, sharing or inadequate protection of customer information, and from actions taken by government regulators and community organizations in response to that conduct.

Competition in the banking industry is intense and Nicolet faces strong competition from larger, more established competitors.

The banking business is highly competitive, and we experience strong competition from many other financial institutions, as well as financial technology companies (“fintechs”). We compete with commercial banks, credit unions, savings and loan associations, mortgage banking firms, consumer finance companies, securities brokerage firms, insurance companies, money market funds, and other financial institutions that operate in our primary market areas and elsewhere. Because technology and other changes have lowered barriers to entry and made it possible for non-banks to offer products and services traditionally provided by banks, we also compete with fintechs seeking to disrupt conventional banking markets. In particular, the activity of fintechs has grown significantly over recent years and is expected to continue to grow. Fintechs have and may continue to offer bank or bank-like products and a number of fintechs have applied for bank or industrial loan charters. In addition, other fintechs have partnered with existing banks to allow them to offer deposit products to their customers.

We compete with these institutions both in attracting deposits and in making loans. In addition, we have to attract our customer base from other existing financial institutions and from new residents. Many of our competitors are well-established, much larger financial institutions. While we believe we can and do successfully compete with these other financial institutions, we may face a competitive disadvantage as compared to large national or regional banks as a result of our smaller size and relative lack of geographic diversification.

Although we compete by concentrating our marketing efforts in our primary market area with local advertisements, personal contacts, and greater flexibility in working with local customers, we can give no assurance that this strategy will be successful.

Nicolet continually encounters technological change, we may have fewer resources than our competition to continue to invest in technological improvements.

The banking and financial services industry is undergoing rapid technological changes, with frequent introductions of new technology-driven products and services. In addition to better serving customers, the effective use of technology increases efficiency and enables financial institutions to reduce costs. Our future success will depend, in part, upon our ability to address the needs of our customers by using technology to provide products and services that enhance customer convenience, as well as create additional efficiencies in operations. Many of our competitors have greater resources to invest in technological improvements, and we may not

be able to effectively implement new technology-driven products and services, which could reduce our ability to effectively compete.

Risks Related to Ownership of Nicolet’s Common Stock

Our stock price can be volatile.

Stock price volatility may make it more difficult for you to sell your common stock when you want and at prices you find attractive. Our stock price can fluctuate widely in response to a variety of factors including, among other things:

•actual or anticipated variations in quarterly results of operations or financial condition;

•operating results and stock price performance of other companies that investors deem comparable to us;

•news reports relating to trends, concerns, and other issues in the financial services industry;

•perceptions in the marketplace regarding us and / or our competitors;

•new technology used or services offered by competitors;

•significant acquisitions or business combinations, strategic partnerships, joint ventures, or capital commitments by or involving us or our competitors;

•failure to integrate acquisitions or realize anticipated benefits from acquisitions;

•changes in government regulations;

•geopolitical conditions such as acts or threats of terrorism or military conflicts;

•available supply and demand of investors interested in trading our common stock;

•our own participation in the market through our buyback program; and

•recommendations by securities analysts.

General market fluctuations, industry factors, and general economic and political conditions and events, such as economic slowdowns or recessions, interest rate changes, or credit loss trends, could also cause our stock price to decrease regardless of our operating results.

Nicolet has not historically paid dividends to our common shareholders, and we cannot guarantee that it will pay dividends to such shareholders in the future.

The holders of our common stock receive dividends if and when declared by the Nicolet board of directors out of legally available funds. Nicolet’s board of directors has not declared a dividend on the common stock since our inception in 2000. Any future determination relating to dividend policy will be made at the discretion of Nicolet’s board of directors and will depend on a number of factors, including the company’s future earnings, capital requirements, financial condition, future prospects, regulatory restrictions and other factors that the board of directors may deem relevant.

Our principal business operations are conducted through the Bank. Cash available to pay dividends to our shareholders is derived primarily, if not entirely, from dividends paid by the Bank. The ability of the Bank to pay dividends to us, as well as our ability to pay dividends to our shareholders, is subject to and limited by certain legal and regulatory restrictions, as well as contractual restrictions related to our junior subordinated debentures. Further, any lenders making loans to us may impose financial covenants that may be more restrictive than regulatory requirements with respect to the payment of dividends by us. There can be no assurance of whether or when we may pay dividends in the future.

Nicolet may need to raise additional capital in the future but that capital may not be available when it is needed or may be dilutive to our shareholders.

We are required by federal and state regulatory authorities to maintain adequate capital levels to support our operations. In order to support our growth and operations and to comply with regulatory standards, we may need to raise capital in the future. Our ability to raise additional capital will depend on conditions in the capital markets at that time, which are outside our control, and on our financial performance. Accordingly, we cannot assure you of our ability to raise additional capital, if needed, on favorable terms. The capital and credit markets have experienced significant volatility in recent years. In some cases, the markets have produced downward pressure on stock prices and credit availability for certain issuers without regard to those issuers’ underlying financial strength. If current levels of volatility worsen, our ability to raise additional capital may be disrupted. If we cannot raise additional capital when needed, our results of operations and financial condition may be adversely affected, and our banking regulators may subject us to regulatory enforcement action, including receivership. In addition, the issuance of additional shares of our equity securities will dilute the economic ownership interest of our common shareholders.

Nicolet’s directors and executive officers own a significant portion of our common stock and can influence shareholder decisions.

Our directors and executive officers, as a group, beneficially owned approximately 13% of our fully diluted issued and outstanding common stock as of December 31, 2021. As a result of their ownership, our directors and executive officers have the ability, if they

voted their shares in concert, to influence the outcome of matters submitted to our shareholders for approval, including the election of directors.

Holders of Nicolet’s subordinated debentures have rights that are senior to those of its common shareholders.

We have supported our continued growth by issuing trust preferred securities and accompanying junior subordinated debentures and by assuming the trust preferred securities and accompanying junior subordinated debentures issued by companies we have acquired. As of December 31, 2021, we had outstanding trust preferred securities and associated junior subordinated debentures with an aggregate par principal amount of approximately $49.8 million and $48.0 million, respectively.

We have unconditionally guaranteed the payment of principal and interest on our trust preferred securities. Also, the junior subordinated debentures issued to the special purpose trusts that relate to those trust preferred securities are senior to our common stock. As a result, we must make payments on the junior subordinated debentures before we can pay any dividends on our common stock, and in the event of our bankruptcy, dissolution or liquidation, holders of our junior subordinated debentures must be satisfied before any distributions can be made on our common stock. We do have the right to defer distributions on our junior subordinated debentures (and related trust preferred securities) for up to five years, but during that time would not be able to pay dividends on our common stock.

Because Nicolet is a regulated bank holding company, your ability to obtain “control” or to act in concert with others to obtain control over Nicolet without the prior consent of the Federal Reserve or other applicable bank regulatory authorities is limited and may subject you to regulatory oversight.

Nicolet is a bank holding company and, as such, is subject to significant regulation of its business and operations. In addition, under the provisions of the Bank Holding Company Act and the Change in Bank Control Act, certain regulatory provisions may become applicable to individuals or groups who are deemed by the regulatory authorities to “control” Nicolet or our subsidiary bank. The Federal Reserve and other bank regulatory authorities have very broad interpretive discretion in this regard and it is possible that the Federal Reserve or some other bank regulatory authority may, whether through a merger or through subsequent acquisition of Nicolet’s shares, deem one or more of Nicolet’s shareholders to control or to be acting in concert for purposes of gaining or exerting control over Nicolet. Such a determination may require a shareholder or group of shareholders, among other things, to make regulatory filings under the Change in Bank Control Act, including disclosure to the regulatory authorities of significant amounts of confidential personal or corporate financial information. In addition, certain groups or entities may also be required to either register as a bank holding company under the Bank Holding Company Act, becoming themselves subject to regulation by the Federal Reserve under that Act and the rules and regulations promulgated thereunder, which may include requirements to materially limit other operations or divest other business concerns, or to divest immediately their investments in Nicolet.

In addition, these limitations on the acquisition of our stock may generally serve to reduce the potential acquirers of our stock or to reduce the volume of our stock that any potential acquirer may be able to acquire. These restrictions may serve to generally limit the liquidity of our stock and, consequently, may adversely affect its value.

Nicolet’s securities are not FDIC insured.

Our securities are not savings or deposit accounts or other obligations of the Bank, and are not insured by the Deposit Insurance Fund, or any other agency or private entity and are subject to investment risk, including the possible loss of some or all of the value of your investment.

ITEM 2. PROPERTIES

The corporate headquarters of both the Parent Company and the Bank are located at 111 North Washington Street, Green Bay, Wisconsin. At year-end 2021, including the main office, the Bank operated 52 bank branch locations, 40 of which are owned and 12 that are leased. In addition, Nicolet owns or leases other real property that, when considered in aggregate, is not significant to its financial position. Most of the offices are free-standing, newer buildings that provide adequate access, customer parking, and drive-through and/or ATM services. The properties are in good condition and considered adequate for present and near term requirements. None of the owned properties are subject to a mortgage or similar encumbrance.

One leased location involves a director, with lease terms that management considers arms-length. For additional disclosure, see Note 15, “Related Party Transactions,” of the Notes to Consolidated Financial Statements under Part II, Item 8.

ITEM 3. LEGAL PROCEEDINGS

We and our subsidiaries may be involved from time to time in various routine legal proceedings incidental to our respective businesses. Neither we nor any of our subsidiaries are currently engaged in any legal proceedings that are expected to have a

ITEM 5. MARKET FOR REGISTRANT’S COMMON EQUITY, RELATED STOCKHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES

Stock. Nicolet’s common stock trades on the Nasdaq Capital Market under the symbol “NCBS”. As of February 22, 2022, Nicolet had approximately 3,800 shareholders of record.

Dividends. Nicolet has not paid dividends on its common stock since its inception in 2000. The payment of dividends is a decision of our Board based upon then-existing circumstances, including our rate of growth, profitability, financial condition, existing and anticipated capital requirements, the amount of funds legally available for the payment of cash dividends, regulatory constraints and such other factors as the Board determines relevant. For the foreseeable future, we do not intend to declare cash dividends, as we intend to retain earnings to grow our business and strengthen our capital base, while returning value to our shareholders by continuing to repurchase shares from time to time. Any cash dividends paid by Nicolet on its common stock must comply with applicable Federal Reserve policies described further in “Business—Regulation of Nicolet—Dividend Restrictions.” The Bank is also subject to regulatory restrictions on the amount of dividends it is permitted to pay to Nicolet as further described in “Business—Regulation of the Bank—Payment of Dividends” and in Note 17, “Regulatory Capital Requirements,” in the Notes to Consolidated Financial Statements under Part II, Item 8.

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion is management’s analysis to assist in the understanding and evaluation of the consolidated financial condition and results of operations of Nicolet. It should be read in conjunction with the consolidated financial statements and footnotes and the selected financial data presented elsewhere in this report.

Evaluation of financial performance and certain balance sheet line items was impacted by the timing and size of Nicolet’s 2021 acquisitions, County Bancorp, Inc. (“County”) and Mackinac Financial Corporation (“Mackinac”). Certain income statement results, average balances and related ratios for 2021 include partial contributions from County and Mackinac, each from the respective acquisition date. Additional information on Nicolet’s recent acquisition activity is included in Note 2, “Acquisitions” in the Notes to Consolidated Financial Statements, under Part II, Item 8.

The detailed financial discussion that follows focuses on 2021 results compared to 2020. For a discussion of 2020 results compared to 2019, see the information under the caption “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020, filed with the SEC on February 26, 2021, which information under that caption is incorporated herein by reference. Historical results of operations are not necessarily predictive of future results.

Overview

2021 Highlights

In 2021, Nicolet delivered on growth, profitability, capital positioning, and sound asset quality management.  On December 3, 2021, Nicolet completed its acquisition of County for a total purchase price of $224 million, including the issuance of 2.4 million shares of common stock valued at $176 million and the remainder in cash consideration. County added total assets of $1.4 billion, loans of $1.0 billion, and deposits of $1.0 billion, at acquisition. On September 3, 2021, Nicolet completed its acquisition of Mackinac for a total purchase price of $229 million, comprised of stock consideration of $180 million, or 2.3 million shares of common stock, and cash consideration of $49 million. At acquisition, Mackinac added total assets of $1.6 billion, loans of $0.9 billion, and deposits of $1.4 billion.

Net income for the year ended December 31, 2021 was $61 million and earnings per diluted common share was $5.44, compared to net income of $60 million and earnings per diluted common share of $5.70 for 2020. Non-core items, and the related tax effect of each, in net income included merger and integration related expenses, Day 2 credit provision expense required under the CECL model, branch optimization costs, and gains on other investments. For the full year, non-core items negatively impacted diluted earnings per common share $1.13 for 2021 and $0.24 for 2020.

At December 31, 2021, Nicolet had total assets of $7.7 billion, an increase of $3.1 billion (69%) over December 31, 2020, largely due to the acquisitions of Mackinac and County. Total loans increased $1.8 billion (66%) and total deposits increased $2.6 billion (65%) from December 31, 2020, also largely due to the acquisitions of Mackinac and County. Total stockholders’ equity was $892 million at December 31, 2021, an increase of $353 million since December 31, 2020, mostly due to the common stock issued in the Mackinac and County acquisitions. For the year ended December 31, 2021, Nicolet repurchased approximately 793,000 shares of common stock for a total cost of $61.5 million, or an average cost of $77.50 per share.

Nonperforming assets were $56 million at December 31, 2021, consisting of $44 million of nonaccrual loans (largely due to nonaccrual agricultural loans acquired with County) and $12 million of other real estate owned (primarily closed bank branch properties yet to be sold), and representing 0.73% of total assets, compared to $13 million or 0.29% at year-end 2020. The allowance for credit losses-loans increased to $50 million (1.07% of loans), mostly due to the Day 2 allowance increase from acquisitions.

Nicolet’s board and management team has several objectives in 2022, with the primary being to ensure the successful cultural integration of the Mackinac and County acquisitions from the prior year. The respective branch and system conversions of both acquisitions were completed with very little disruption to our customers during 2021. However, as with any sizable acquisition, the melding of cultures does not happen immediately, and takes a tremendous amount of effort by our entire employee base. We have worked hard to retain the right people and hire new talent in many of the markets we’ve entered in the past year. As with past acquisitions, we plan to show how our words matter, and will be investing in the new communities we now serve. While new acquisitions take time and resources to fully integrate, we don’t plan to lose sight of our core franchise. We expect to achieve solid organic growth in loans, deposits, wealth management service revenue, and other revenue lines across our footprint. As the U.S. economy continues to emerge from the pandemic of the past two years, there will be several economic policy changes that will impact the banking industry in the coming year and beyond. Nicolet is an asset sensitive bank, and therefore an increase in interest rates is expected to increase our net interest income over time. As interest rates are currently forecasted to increase several times during 2022, we expect our revenues to be positively impacted, although the degree to which remains unknown given several factors

at play. We believe 2022 will be another year of opportunity, and have positioned the Company to take advantage by maintaining a solid balance sheet funded almost entirely by core deposits, ample liquidity, and prudent capital management. Nicolet enters 2022 as a “well capitalized” financial institution with more than $80 million in cash at its holding company. We expect this cash to be deployed through continued use of our share repurchase program, potential acquisitions, and other strategic long-term investments that will position Nicolet for years to come.

Pandemic Effects, Actions and Updates

The 2020 year was marked by significant events (health pandemic, large sudden rate drop by the Federal Reserve, unprecedented government stimulus, political changes and social issues, and other market and economic disruptions), volatility, and uncertainty, that turned 2020 into a very tactical year for Nicolet management. Management took several actions to respond: added $0.2 billion of liquidity (which later proved to not be necessary, leading to a reduction in non-deposit leverage in the second half of the year), temporarily (and later permanently) closed 8 branches, provided temporary relief to customers through loan payment modifications on nearly 1,000 loans (with only a fraction remaining on modified terms at year end 2020), dramatically elevated the credit loss provision given pervading uncertainty (though slowed the provision in fourth quarter as potential deterioration of loan quality metrics initially anticipated had not materialized), channeled significant resources to originate Paycheck Protection Program (“PPP”) loans (peaking at 2,725 loans totaling $351 million during 2020) and residential mortgages (over $1 billion originated to consumers under atypical conditions), granted $1.25 million of aid to expedite funds to smaller businesses who would have otherwise waited for small PPP loans, kept people safe (with $0.6 million of expense in second quarter for onsite-bonuses, testing and protective supplies), and prioritized full return to on-site work by June to allow us to move forward on goals and improvements. During 2020, we still executed on our acquisition strategy, completing the all-cash acquisition of Advantage.

The dramatic events surrounding the pandemic, fluctuating social and economic changes since the onset of the pandemic, and uncertainty about the longevity of the pandemic’s effects have abated somewhat during 2021 as consumers and businesses were supported by government stimulus and the vaccination rollout. Despite these challenges, Nicolet continues to focus on serving the needs of its communities, including originating 2,205 PPP loans totaling $160 million during 2021, as well as serving our communities through charitable donations, volunteerism, and community events. However, much uncertainty remains from new strains of the virus, ongoing supply chain issues and competitive labor markets, which could result in continued volatility.

(1) The ratios of tangible book value per common share, return on average tangible common equity, and tangible common equity to tangible assets exclude goodwill and other intangibles, net. These financial ratios have been included as they are considered to be critical metrics with which to analyze and evaluate financial condition and capital strength.

Non-GAAP Financial Measures

We identify “tangible book value per common share,” “return on average tangible common equity,” “tangible common equity to tangible assets” “adjusted net income,” and “adjusted diluted earnings per common share” as “non-GAAP financial measures.” In accordance with the SEC’s rules, we identify certain financial measures as non-GAAP financial measures if such financial measures exclude or include amounts in the most directly comparable measures calculated and presented in accordance with generally accepted accounting principles (“GAAP”) in effect in the United States in our statements of income, balance sheet or statements of cash flows. Non-GAAP financial measures do not include operating and other statistical measures, ratios or statistical measures calculated using exclusively financial measures calculated in accordance with GAAP.

Management believes that the presentation of these non-GAAP financial measures (a) are important metrics used to analyze and evaluate our financial condition and capital strength and provide important supplemental information that contributes to a proper understanding of our operating performance and trends, (b) enables a more complete understanding of factor and trends affecting our business, and (c) allows investors to compare our financial performance to the financial performance of our peers and to evaluate our performance in a manner similar to management, the financial services industry, bank stock analysts, and bank regulators. Management uses non-GAAP measures as follows: in the preparation of our operating budgets, monthly financial performance reporting, and in our presentation to investors of our performance. However, we acknowledge that these non-GAAP financial measures have a number of limitations. Limitations associated with non-GAAP financial measures include the risk that persons might disagree as to the appropriateness of items comprising these measures and that different companies might calculate these measures differently. These disclosures should not be considered an alternative to our GAAP results. A reconciliation of non-GAAP financial measures to the most directly comparable GAAP financial measures is presented in the table above.

INCOME STATEMENT ANALYSIS

Net Interest Income

Net interest income is the primary source of Nicolet’s revenue, and is the difference between interest income on earning assets, such as loans and investment securities, and interest expense on interest-bearing liabilities, such as deposits and other borrowings. Net interest income is directly impacted by the sensitivity of the balance sheet to changes in interest rates and by the amount, mix and composition of interest-earning assets and interest-bearing liabilities, including characteristics such as the fixed or variable nature of the financial instruments, contractual maturities, and repricing frequencies. Tax-equivalent net interest income is a non-GAAP measure, but is a preferred industry measurement of net interest income (and is used in calculating a net interest margin) as it enhances the comparability of net interest income arising from taxable and tax-exempt sources. 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.

Comparison of 2021 versus 2020

Short-term interest rates have remained steady since March 2020, while the yield curve has begun to steepen since year end 2020. The succeeding quarters felt the pressure of a low interest rate environment and bloated cash balances from government stimulus, both in the form of stimulus checks to individuals and PPP loans for businesses. The continued elevation of low interest-earning asset balances have further decreased margins along with the normal pressures of a near-zero rate environment. Though margins remain depressed, interest income dollars continue to rise on favorable asset volumes and proactive expense reduction measures. The following paragraphs will discuss the comparison of 2021 and 2020, with the pandemic impacts appearing second quarter 2020 and the economy beginning to rebound in the first part of 2021. Though improving, we see continued margin pressure and pricing impacts on loans and deposits.

Tax-equivalent net interest income was $159 million for 2021, comprised of net interest income of $158 million ($29 million or 22% higher than 2020) and a $1 million tax-equivalent adjustment. The increase in tax-equivalent net interest income was comprised of $22 million higher interest income and $6 million lower interest expense. Higher volumes added $24 million to interest income (mostly from higher loan volumes related to the Mackinac and County acquisitions and organic loan growth, as well as growth in other interest-earning assets), offset partly by a $2 million increase to interest expense on higher interest-bearing liabilities (also mostly from volumes due to the Mackinac and County acquisitions, as well as $100 million of subordinated notes issued in July 2021). Rate changes added $7 million to net interest income, mostly due to $9 million lower interest expense (including $7 million from prudent deposit pricing actions on interest-bearing core deposits).

Average interest-earning assets were $4.7 billion for 2021, $0.9 billion (23%) higher than 2020. Average loans increased $396 million (14%) to $3.2 billion, largely due to the timing of the acquisitions (with Mackinac adding $0.9 billion at acquisition in September 2021 and County adding $1.0 billion at acquisition in December 2021). Investment securities increased $248 million, including growth related to the acquisitions, as well as the strategic re-investment of approximately $0.5 billion excess cash liquidity into U.S. Treasury securities of varying yields and durations during fourth quarter 2021. Other interest-earning assets were up $225

million, mostly cash, reflecting the continued liquidity of businesses and consumers. As a result, the mix of average interest-earning assets shifted. Other interest-earning assets increased to 17% of total interest-earning assets for 2021 (compared to 15% for 2020) and investment securities increased to represent 16% of total interest-earning assets for 2021 (compared to 13% in 2020), while the percentage of loans decreased to represent 67% of total interest-earning assets for 2021 (compared to 72% in the prior year).

Average interest-bearing liabilities were $3.1 billion for 2021, an increase of $480 million (18%) from 2020, primarily due to the significant increase in deposits from government stimulus activities and deposited PPP loan proceeds, as well as the timing of the acquisitions (Mackinac in September 2021 and County in December 2021). Average core interest-bearing deposits increased $605 million and brokered deposits grew $19 million, while funding decreased $143 million (mostly PPPLF funding). The mix of average interest-bearing liabilities was 87% core deposits, 10% brokered deposits, and 3% other funding for 2021, compared to 80% core deposits, 11% brokered deposits, and 9% other funding in 2020.

The interest rate spread increased 8 bps between the periods, attributable to the low interest rate environment and the changing balance sheet mix. The 2021 interest-earning asset yield decreased 24 bps to 3.66% for 2021, largely due to the lower loans-to-earning asset mix given the higher mix of cash assets (as noted above) combined with continued decline in yield (to 0.36% versus 0.46% in 2020). Loans yielded 4.92% for 2021, up slightly (2 bps) from 2020, mostly from the yield on PPP loans (at 11.78% for 2021), as the yield on all other loans decreased 40 bps (to 4.60%) largely from the lower interest rate environment continuing to impact yields on new, renewed and variable rate loans. Investments yielded 1.77%, 49 bps lower than 2020, attributable to the lower rate environment along with the strategic re-investment of excess cash put into lower yielding U.S. Treasuries, compared to the mix of the balance of the portfolio. The cost of funds declined 32 bps to 0.43% for 2021, mainly due to lower rates on core interest-bearing deposits (down 33 bps to 0.24%), as well as the changing mix of interest-bearing liabilities (as noted above). The contribution from net free funds decreased 9 bps, due mostly to the reduced value in the lower interest rate environment, though offset partly by the increase in average net free funds (largely from higher average noninterest-bearing demand deposits and stockholders’ equity) between the years. As a result, the net interest margin was 3.37% for 2021, down 1 bps compared to 3.38% for 2020.

Tax-equivalent interest income was $173 million, up $22 million (15%) over 2020. Interest income on loans increased $20 million (15%) over 2020, mostly due to strong volumes from the 2021 acquisitions and organic loan growth. Between the years, interest income on investment securities increased $2 million to $13 million, with $3 million from higher average volumes due to the 2021 acquisitions and strategic re-investment of cash (as noted above), partially offset by $1 million lower rate from declining yields in the low interest rate environment. Interest expense was $14 million for 2021, down $6 million (32%) from 2020. Interest expense on deposits decreased $6 million from 2020 given higher average deposit balances at a lower cost (down 35 bps to 0.34%) as product rate changes were made in the lower interest rate environment, and brokered deposits cost 32 bps less (largely from maturities of higher-costing term brokered funds procured under competitive conditions in mid-2020 during the pandemic). Interest expense on wholesale funding was minimally changed (down 2%), as interest expense on lower average balances (down $143 million, mostly PPPLF) was offset by higher rates (up 175 bps to 3.06%), reflecting the July 2021 subordinated notes issuance ($100 million at 3.125%), debt acquired with County, and the inclusion of the low-costing PPPLF during 2020.

Provision for Credit Losses

The provision for credit losses in 2021 was $14.9 million (comprised of $12.5 million related to the ACL-Loans, and $2.4 million for the ACL on unfunded commitments). The 2021 provision for credit losses was mostly due to the required Day 2 ACL increase from the acquisitions of County and Mackinac. Comparatively, 2020 provision for credit losses was $10.3 million largely due to the unprecedented economic disruptions and uncertainty surrounding the COVID pandemic. Net charge-offs were negligible for both years.

The provision for credit losses is predominantly a function of Nicolet’s methodology and judgment as to qualitative and quantitative factors used to determine the appropriateness of the ACL-Loans. The appropriateness of the ACL-Loans is affected by changes in the size and character of the loan portfolio, changes in levels of collateral-dependent 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. For additional information regarding asset quality and the ACL-Loans, see “BALANCE SHEET ANALYSIS — Loans,” and “— Allowance for Credit Losses - Loans” and “—Nonperforming Assets.”

Comparison of 2021 versus 2020

Noninterest income was $67 million for 2021, an increase of $5 million (8%) over 2020. Excluding net asset gains (losses), noninterest income for 2021 was down $1 million (2%) compared to 2020. Notable contributions to the change in noninterest income were:

•Trust services fee income and brokerage fee income combined were $20 million for 2021, up $4 million (23%) from 2020, consistent with the growth in accounts and assets under management.

•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 net of MSR amortization, fair value marks on the mortgage interest rate lock commitments and forward commitments (“mortgage derivatives”), and MSR valuation changes, if any. Net mortgage income was $22 million for 2021, down $8 million (26%) between the years, predominantly on slowing mortgage activity from the record levels experienced in 2020. Gains on sales and capitalized gains combined decreased $9 million, commensurate with the lower volume of loans sold into the secondary market, while MSR impairment was down $1 million on slower paydown activity. See also “Off-Balance Sheet Arrangements, Lending-Related Commitments and Contractual Obligations” and Note 6, “Goodwill and Other Intangibles and Servicing Rights” in the Notes to Consolidated Financial Statements, under Part II, Item 8

•Service charges on deposit accounts were up $1 million (19%) to $5 million for 2021, partly due to the waiver of certain fees during 2020 to provide economic relief to our customers at the inception of the pandemic and partly due to the larger deposit base from the 2021 acquisitions.

•Card interchange income grew $2 million (31%) to $9 million in 2021 largely due to higher volume and activity, though 2020 activity was also tempered by cautionary spending of consumers given the economic uncertainty of the pandemic.

•BOLI income decreased $0.3 million (12%) to $2 million for 2021, attributable to BOLI death benefits received in 2020, partly offset by income on higher average balances from the BOLI acquired in recent acquisitions.

•The $4 million net asset gains in 2021 were primarily attributable to favorable fair value marks on equity securities (including $3.5 million related to the initial public offering of an equity investment). Net asset losses in 2020 of $2 million were comprised primarily of $1 million market losses on equity securities held in the lower, more volatile market and $1 million of net losses on branch other real estate owned write-downs.

Comparison of 2021 versus 2020

Noninterest expense was $129 million, an increase of $29 million (28%) over 2020. Personnel costs increased $13 million, while non-personnel expenses combined increased $15 million over 2020. Notable contributions to the change in noninterest expense were:

•Personnel expense (including salaries, overtime, cash and equity incentives, and employee benefit and payroll-related expenses) was $71 million for 2021, an increase of $13 million (24%) over 2020. Salary expense increased $5 million (16%) over 2020, reflecting higher salaries from the larger employee base (with average full-time equivalent employees up 13%) as well as merit increases between the years. Cash, equity and other incentives increased $6 million, reflective of the strong earnings for the year, the successful integration of two acquisitions, and large option grants during the year (intended to align incentives with future strategic goals). Fringe benefits increased $2 million over 2020, mainly on higher health costs between the years.

•Occupancy, equipment and office expense was $21 million for 2021, up $4 million (26%) from 2020, with 2021 including $0.9 million of accelerated depreciation and write-offs related to the branch closures, as well as higher expense for the expanded branch network with the Mackinac and County acquisitions, and additional expense for software and technology to drive operational efficiencies, and enhance products or services. 2020 also included $0.5 million of accelerated depreciation and write-offs related to branch closures.

•Business development and marketing expense was $5 million for 2021, minimally changed from 2020. During 2021, business development costs have increased as travel and entertainment is returning to more normal levels (though still down from pre-pandemic levels), as well as lower marketing costs from differences in the timing and extent of donations, marketing campaigns, promotions, and media. In comparison, business development costs during 2020 were low from less travel and entertainment during the pandemic. In addition, 2020 also included $1.25 million for the micro-grant program (which provided funds directly to customers who otherwise qualified for small PPP loans of less than $5,000, as a more cost beneficial result for the customer).

•Data processing expense was $12 million for 2021, up $1.5 million (14%) over 2020, mostly due to volume-based increases in core processing charges, as well as the larger operating base following the Mackinac and County acquisitions.

•Intangible amortization was down slightly (2%) between the years, with the declining amortization on the aging intangibles of previous acquisitions, substantially offset by amortization from the new intangibles of recent acquisitions.

•FDIC assessments increased to $2 million for 2021 as the small bank assessment credits were fully utilized during third quarter 2020, and also reflecting the higher assessment base.

•Other expense was $9 million for 2021, up $3 million (59%) from 2020, mostly due to an increase in director fees (reflective of the additional complexity of a larger company, including the addition of four new directors), higher professional fees, costs to carry closed bank branches, and overall higher expenses related to the larger operating base. In addition, 2021 included a $2 million contract termination charge, while 2020 included $1 million of lease termination charges related to the branch closures.

Income Taxes

Income tax expense was $20 million (effective tax rate of 25.2%) for 2021, unchanged from 2020 income tax expense (effective tax rate of 25.3%). The accounting for income taxes requires deferred income taxes to be analyzed to determine if a valuation allowance is required. A valuation allowance is required if it is more likely than not that some portion of the deferred tax asset will not be realized. This analysis involves the use of estimates, assumptions, interpretation, and judgment concerning accounting pronouncements and federal and state tax codes; therefore, income taxes are considered a critical accounting policy. At December 31, 2021 and 2020, no valuation allowance was determined to be necessary. Additional information on the subjectivity of income taxes is discussed further under “Critical Accounting Policies-Income Taxes.” The Company’s income taxes accounting policy is described in Note 1, “Nature of Business and Significant Accounting Policies,” and additional disclosures relative to income taxes are included in Note 13, “Income Taxes” in the Notes to Consolidated Financial Statements, under Part II, Item 8.

Total loans ex. PPP loans	$	4,597,305	99	%	$	2,603,085	93	%	$	2,573,751	100	%

Total loans were $4.6 billion at December 31, 2021, an increase of $1.8 billion (66%), compared to total loans of $2.8 billion at December 31, 2020. The increase in loans during 2021 was largely due to the acquisitions of Mackinac and County, which added total loans of $0.9 billion and $1.0 billion, respectively, at acquisition, and also shifted the composition of the loan portfolio. In addition, during 2021, under the latest round of the SBA’s program, we originated 2,205 PPP loans totaling $160 million, bearing a 1% contractual rate, and earned a $9 million fee. In comparison, during 2020 we originated 2,725 PPP loans totaling $351 million and earned a $12 million fee. Of the total fees, $15 million was accreted into interest income during 2021 and $6 million was accreted during 2020. At December 31, 2021, the net carrying value of PPP loans was $25 million, or 1% of loans, with the decline in balance due to SBA loan forgiveness.

As noted in Table 6 above, year-end 2021 loans were broadly 80% commercial-based and 20% retail-based compared to 78% commercial-based and 22% retail-based at year-end 2020. Commercial-based loans are considered to have more inherent risk of

default than retail-based loans, in part because the commercial balance per borrower is typically larger than that for retail-based loans, implying higher potential losses on an individual customer basis.

Commercial and industrial loans consist primarily of commercial loans to small businesses, PPP loans, and, to a lesser degree, to municipalities within a diverse range of industries. The credit risk related to commercial and industrial 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 and industrial loans, including the PPP loans, continue to be the largest segment of Nicolet’s portfolio, representing 23% of the portfolio at year-end 2021.

Owner-occupied CRE loans represented 17% of loans at year-end 2021, down from 19% at year-end 2020. This category primarily consists of loans within a diverse range of industries secured by business real estate that is occupied by borrowers who operate their businesses out of the underlying collateral and who may also have commercial and industrial loans. The credit risk related to owner-occupied CRE loans is largely influenced by general economic conditions and the resulting impact on a borrower’s operations, or on the value of underlying collateral.

Agricultural loans consist of loans secured by farmland and the related farming operations. The credit risk related to agricultural loans is largely influenced by the agricultural economy, including market prices for the cost of feed and the price of milk, and/or the underlying value of the farmland. These loans represented 17% of loans at year-end 2021, compared to 4% a year ago, with the increase attributable to the acquisition of County.

The CRE investment loan classification primarily includes commercial-based mortgage loans that are secured by non-owner occupied, nonfarm/nonresidential real estate properties, and multi-family residential properties. Lending in this segment has been focused on loans that are secured by commercial income-producing properties as opposed to speculative real estate development. These loans represented 18% of loans at December 31, 2021, compared to 16% of loans at year-end 2020.

Loans in the construction and land development portfolio represented 5% of total loans at year-end 2021, unchanged from a year ago. Construction and land development loans provide financing for the development of commercial income properties, multi-family residential development, and land designated for future development. Nicolet controls the credit risk on these types of loans by making loans in familiar markets, reviewing the merits of individual projects, controlling loan structure, and monitoring the progress of projects through the analysis of construction advances. Credit risk is managed by employing sound underwriting guidelines, lending primarily to borrowers in local markets, periodically evaluating the underlying collateral, and formally reviewing the borrower’s financial soundness and relationships on an ongoing basis.

On a combined basis, Nicolet’s residential real estate loans represented 19% of total loans at year-end 2021 compared to 21% of total loans at year-end 2020. Residential first mortgage loans include conventional first-lien home mortgages. Residential junior mortgage loans consist 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 first mortgage loans are sold in the secondary market with the servicing rights retained. Nicolet’s mortgage loans are typically of high quality and have historically had low net charge-off rates.

Loans in the retail and other classification represented approximately 1% of the total loan portfolio, and include predominantly short-term and other personal installment loans not secured by real estate. Credit risk is primarily controlled by reviewing the creditworthiness of the borrowers, monitoring payment histories, and taking appropriate collateral and/or guaranty positions.

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 ACL-Loans, and sound nonaccrual and charge-off policies. An active credit risk management process is used for commercial loans to further ensure that sound and consistent credit decisions are made. The credit management process is regularly reviewed and the process has been enhanced over the past several years to further strengthen the controls.

Allowance for Credit Losses - Loans

In addition to the discussion that follows, accounting policies for the allowance for credit losses - loans are described in Note 1, “Nature of Business and Significant Accounting Policies,” and additional ACL-Loans disclosures are included in Note 4, “Loans, Allowance for Credit Losses - Loans, and Credit Quality,” in the Notes to Consolidated Financial Statements, under Part II, Item 8.

Credit risks within the loan portfolio are inherently different for each loan type as described under “BALANCE SHEET ANALYSIS – Loans.” 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. Loans charged off are subject to continuous review, and specific efforts are taken to achieve maximum recovery of principal, interest, and related expenses. For additional information regarding nonperforming assets see “BALANCE SHEET ANALYSIS – Nonperforming Assets.”

The ACL-Loans represents management’s estimate of expected credit losses in the Company’s loan portfolio at the balance sheet date. To assess the overall appropriateness of the ACL-Loans, management applies an allocation methodology 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 nonaccrual loans; (v) 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 expected credit losses. Assessing these factors involves significant judgment; therefore, management considers the ACL-Loans a critical accounting policy, as further discussed under “Critical Accounting Estimates – Allowance for Credit Losses - Loans.”

Management allocates the ACL-Loans by pools of risk within each loan portfolio segment. The allocation methodology consists of the following components. First, a specific reserve is established for individually evaluated credit deteriorated loans, which management defines as nonaccrual credit relationships over $250,000, collateral dependent loans, purchased credit deteriorated loans, and other loans with evidence of credit deterioration. The specific reserve in the ACL-Loans for these credit deteriorated loans is equal to the aggregate collateral or discounted cash flow shortfall. Second, management allocates the ACL-Loans with historical loss rates by loan segment. The loss factors are measured on a quarterly basis and applied to each loan segment based on current loan balances and projected for their expected remaining life. Next, management allocates the ACL-Loans using the qualitative and environmental factors mentioned above. Consideration is given to those current qualitative or environmental factors that are likely to cause estimated credit losses at the evaluation date to differ from the historical loss experience of each loan segment. Lastly, management considers reasonable and supportable forecasts to assess the collectability of future cash flows.

Management performs ongoing intensive analysis of its loan portfolio to allow for early identification of customers experiencing financial difficulties, maintains prudent underwriting standards, understands the economy in its markets, and considers the trend of deterioration in loan quality in establishing the level of the ACL-Loans. In addition, various regulatory agencies periodically review the ACL-Loans. These agencies may require the Company to make additions to the ACL-Loans or may require that certain loan balances be charged off or downgraded into classified loan categories when their credit evaluations differ from those of management based on their judgments of collectability from information available to them at the time of their examination.

At December 31, 2021, the ACL-Loans was $50 million (representing 1.07% of period end loans) compared to $32 million at December 31, 2020. The increase in the ACL-Loans was largely due to the acquisitions of Mackinac and County, which combined added $12 million of provision for the Day 2 allowance and $5 million related to purchased credit deteriorated loans. Net charge-offs (0.01% of average loans) remain negligible. The components of the ACL-Loans are detailed further in Tables 8 and 9 below.

The allocation of the ACL-Loans by loan category for each of the past three years is shown in Table 9. The largest portions of the ACL-Loans were allocated to commercial & industrial loans and agricultural loans, representing 25% and 19%, respectively, of the ACL-Loans at December 31, 2021. In comparison, the largest portions of the ACL-Loans were allocated to commercial & industrial loans and owner-occupied CRE, representing 36% and 18%, respectively, of the ACL-Loans at December 31, 2020. This change in allocated ACL-Loans was attributable to the change in loan portfolio composition, mostly related to the agricultural loans acquired with County, as well as changes in outstanding loan balances between the years and risk trends within loan categories.

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. Management continues to actively work with customers to monitor credit risk from the ongoing economic disruptions surrounding the pandemic. Since the pandemic started, nearly 1,000 loans were provided temporary payment modifications, and as of December 31, 2021, no loans remain under temporary payment modification structure. In addition to the discussion that follows, accounting policies for loans and the ACL-Loans are described in Note 1, “Nature of Business and Significant Accounting Policies,” and additional credit quality disclosures are included in Note 4, “Loans, Allowance for Credit Losses - Loans, and Credit Quality,” in the Notes to Consolidated Financial Statements, under Part II, Item 8.

Nonperforming loans are considered one indicator of potential future loan losses. Nonperforming loans are defined as nonaccrual loans 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. Nonperforming assets (which include nonperforming loans and other real estate owned “OREO”) were $56 million at December 31, 2021, compared to $13 million at December 31, 2020. Nonaccrual loans were $44 million at December 31, 2021, compared to $9 million at December 31, 2020, with the increase largely due to the nonaccrual agricultural loans acquired with County. OREO was $12 million at December 31, 2021, up from $4 million at year-end 2020, with the increase primarily due to the addition of closed bank branch properties. Nonperforming assets as a percent of total assets was 0.73% at December 31, 2021, compared to 0.29% at December 31, 2020.

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 ACL-Loans. 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 $53 million (1% of total loans) and $21 million (1% of total loans) at December 31, 2021 and 2020, respectively, with the increase largely due to the agricultural loans acquired with County. 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.

Investment Securities Portfolio

The investment securities portfolio is intended to provide Nicolet with adequate liquidity, flexible asset/liability management and a source of stable income. The portfolio is structured with minimal credit exposure to Nicolet. All investment securities are classified at the time of purchase as available for sale (“AFS”) or held to maturity (“HTM”). In addition to the discussion that follows, the investment securities portfolio accounting policies are described in Note 1, “Nature of Business and Significant Accounting Policies,” and additional disclosures are included in Note 3, “Investment Securities,” in the Notes to Consolidated Financial Statements, under Part II, Item 8.

At December 31, 2021, the investment securities portfolio totaled $1.6 billion, comprised of $922 million securities AFS and $652 million securities HTM (representing 20% of total assets), compared to $539 million, all securities AFS, (representing 12% of total assets) at December 31, 2020. During 2021, the Company purchased approximately $500 million of U.S. Treasury securities (included in U.S. government agency securities) of varying yields and durations, which were classified as HTM, to re-invest a portion of excess cash liquidity. In addition, the acquisitions of Mackinac and County added investment securities totaling $104 million and $300 million, respectively, at acquisition, with a portion of these investment securities designated as HTM at acquisition.

Nicolet also had other investments of $44 million and $28 million at December 31, 2021 and 2020, respectively, consisting of capital stock in the Federal Reserve and the Federal Home Loan Bank (“FHLB”) (required as members of the Federal Reserve Bank System and the FHLB System), equity securities with readily determinable fair values, and to a lesser degree equity investments in other private companies. The FHLB and Federal Reserve investments are “restricted” in that they can only be sold back to the respective institutions or another member institution at par, and are thus not liquid, have no ready market or quoted market value, and are carried at cost. The private company equity investments have no quoted market prices, and are carried at cost less impairment charges, if any. The other investments are evaluated periodically for impairment, considering financial condition and other available relevant information.

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

Deposits

Deposits represent Nicolet’s largest source of funds. The deposit levels in 2021 and 2020 have been heavily influenced by the ongoing economic uncertainty, government stimulus payments and other directives related to the pandemic, which reduced spending and increased liquidity of consumers and businesses, as well as by PPP loan proceeds retained on deposit by commercial borrowers. In addition, Mackinac and County added deposits of $1.4 billion and $1.0 billion, respectively, at acquisition.

Deposits levels may also be impacted by competition with other bank and nonbank institutions, as well as with a number of non-deposit investment alternatives available to depositors, such as mutual funds, money market funds, annuities, and other brokerage investment products. Deposit challenges include competitive deposit product features, price changes on deposit products given movements in the interest rate environment and other competitive pricing pressures, and customer preferences regarding higher-costing deposit products or non-deposit investment alternatives. Additional disclosures on deposits are included in Note 8, “Deposits,” in the Notes to Consolidated Financial Statements, under Part II, Item 8. See Table 2 for information on average deposit balances and deposit rates.

Total customer deposits (core)	$	6,021,753	93	%	$	3,585,538	92	%	$	2,794,262	95	%

Total deposits were $6.5 billion at December 31, 2021, an increase of $2.6 billion (65%) over year-end 2020, largely due to the acquisitions of Mackinac and County, as well as additional government stimulus and new PPP funds on deposit. Since December 31, 2020, customer deposits (core) increased $2.4 billion to represent 93% of total deposits, and brokered deposits increased $0.1 billion to represent 7% of total deposits.

On average, deposits grew $1.1 billion (31%) between 2021 and 2020 (as detailed in Table 2), primarily due to the timing of the acquisitions (Mackinac in September 2021 and County in December 2021) and the liquidity objectives of our customers in uncertain economic times. Average customer deposits (core) increased $1.0 billion (33%), while average brokered deposits were up slightly (6%) over the prior year.

At December 31, 2021, Nicolet had $113 million of time deposits that exceed the Federal Deposit Insurance Corporation (“FDIC”) insurance limit of $250,000. The following table provides information on the maturity distribution of those time deposits, including the portion of those time deposits in excess of the FDIC insurance limits (over $250,000) as of December 31, 2021.

Over 6 months through 12 months	45,988		34,988
Over 12 months	24,684		10,934
Total	$	112,599	$	62,849

Total uninsured deposits were $2.1 billion and $1.2 billion as of December 31, 2021 and 2020, respectively.

Other Funding Sources

Other funding sources include short-term borrowings (zero at both December 31, 2021 and 2020) and long-term borrowings (totaling $217 million and $54 million at December 31, 2021 and 2020, respectively). Short-term borrowings (with an original contractual maturity of one year or less) consist mainly of short-term FHLB advances, customer repurchase agreements or federal funds purchased. Long-term borrowings (with an original contractual maturity of over one year) include FHLB advances, junior subordinated debentures, and subordinated notes. The interest on all long-term borrowings is current.

In July 2021, the Company completed the private placement of $100 million in fixed-to-floating rate subordinated notes due in 2031, with a fixed annual rate of 3.125% for the first five years, and will reset quarterly thereafter to the then current three-month Secured Overnight Financing Rate (“SOFR”) plus 237.5 basis points. In addition, the Company acquired $16 million of junior subordinated debentures and $52 million of subordinated notes as part of the County acquisition. All FHLB advances acquired with the Mackinac and County acquisitions were repaid in full shortly after the respective acquisition dates given our strong core deposit base. See Note 9, “Short and Long-Term Borrowings,” of the Notes to Consolidated Financial Statements under Part II, Item 8 for additional details. See section “Liquidity Management,” for information on available funding sources at December 31, 2021.

RISK MANAGEMENT AND CAPITAL

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.

Given the stable core customer deposit base, fairly consistent patterns of activity in the core deposit base (including extra growth in core deposits related to the pandemic and ongoing economic uncertainty, as previously discussed), and the minimal use of capacity available in numerous non-core funding sources, Nicolet’s liquidity levels and resources have been sufficient to fund loans, accommodate deposit trends and cycles, and to meet other cash needs as necessary. At the onset of the pandemic, but prior to the announcement of government stimulus, management initiated preparatory actions to increase on-balance sheet liquidity to ensure we could meet customer needs. These actions proved later to not be necessary, leading us to reduce non-deposit funding. In addition to this on-balance sheet liquidity build, remaining liquidity facilities continue to provide capacity and flexibility in an uncertain time.

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 additional brokered deposits or other wholesale funding. At December 31, 2021, approximately 18% of the investment securities portfolio was pledged to secure public deposits, as applicable, and for other purposes as required by law. Additional funding sources at December 31, 2021, consist of

$195 million of available and unused Federal funds lines, available borrowing capacity at the FHLB of $355 million, and borrowing capacity in the brokered deposit market.

In consideration of the funds availability for the Bank and the current high levels of cash in a very low interest rate environment, management has taken prudent pricing actions on deposits and loans, as well as actions to reduce non-deposit funding. Brokered deposits have matured without renewal and selected FHLB advances were repaid early.

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. At December 31, 2021, the Parent Company had $85 million in cash. Additional cash sources available to the Parent Company include access to the public or private markets to issue new equity, subordinated notes or other debt. Dividends from the Bank and, to a lesser extent, stock option exercises, represent significant sources of cash flows for the Parent Company. The Bank is required by federal law to obtain prior approval of the OCC for payments of dividends if the total of all dividends declared by the Bank in any year will exceed certain thresholds, as more fully described in “Business—Regulation of the Bank – Payment of Dividends” and in Note 17, “Regulatory Capital Requirements,” in the Notes to the Consolidated Financial Statements under Part II, Item 8. Management does not believe that regulatory restrictions on dividends from the Bank will adversely affect its ability to meet its cash obligations.

Cash and cash equivalents at December 31, 2021 and 2020 were approximately $595 million and $803 million, respectively. The $208 million decrease in cash and cash equivalents since year-end 2020 included $98 million net cash provided by operating activities (mostly earnings), more than offset by $371 million net cash used in investing activities (primarily to purchase investment securities and to fund loan growth) and $65 million net cash provided by financing activities (with funds from increased deposits and the subordinated notes issuance partly offset by the early redemption of selected debt and common stock repurchases). Nicolet’s liquidity resources were sufficient as of December 31, 2021 to fund loans, accommodate deposit trends and cycles, and to meet other cash needs as necessary.

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.

Among other scenarios, 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 results provided include the liquidity measures mentioned above and reflect the changed interest rate environment, partly in response to the pandemic. 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 December 31, 2021 and 2020, the projected changes in net interest income over a one-year time horizon, versus the baseline, are presented in Table 14 below. The results were within Nicolet’s guidelines of not greater than -10% for +/- 100 bps and not greater than -15% for +/- 200 bps, and given the relatively short nature of the Company’s balance sheet, reflect a largely unchanged risk position as expected.

Table 14: Interest Rate Sensitivity

	December 31, 2021		December 31, 2020
200 bps decrease in interest rates	(0.3)	%	(0.8)	%
100 bps decrease in interest rates	(0.3)	%	(0.8)	%
100 bps increase in interest rates	(0.1)	%	4.0	%
200 bps increase in interest rates	(0.3)	%	8.1	%

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. Inflation may also have impacts on the Bank’s customers, on businesses and consumers and their ability or willingness to invest, save or spend, and perhaps on their ability to repay loans. As such, there would likely be impacts on the general appetite of banking products and the credit health of the Bank’s customer base.

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. The capital position and strategies are actively reviewed 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 for shareholder return.

Capital balances and changes in capital are presented in the Consolidated Statements of Changes in Stockholders’ Equity in Part II, Item 8. Further discussion of capital components is included in Note 12, “Stockholders’ Equity,” and a summary of dividend restrictions, as well as regulatory capital amounts and ratios for Nicolet and the Bank is presented in Note 17, “Regulatory Capital Requirements,” of the Notes to Consolidated Financial Statements under Part II, Item 8.

The Company’s and the Bank’s regulatory capital ratios remain well above minimum regulatory ratios, including the capital conservation buffer. At December 31, 2021, 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. For a discussion of the regulatory restrictions applicable to the Company and the Bank, see section “Business-Regulation of Nicolet” and “Business-Regulation of the Bank,” included within Part I, Item 1. A summary of Nicolet’s and the Bank’s regulatory capital amounts and ratios, as well as selected capital metrics are presented in Table 15.

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. Through an ongoing repurchase program, the Board has authorized the repurchase of Nicolet’s common stock as an alternative use of capital. During 2021, $61 million was used to repurchase and cancel approximately 793,000 shares at a weighted average price per share of $77.50. At December 31, 2021, there remained $69 million authorized under this repurchase program, as modified, to be utilized from time to time to repurchase shares in the open market, through block transactions or in private transactions.

Off-Balance Sheet Arrangements, Lending-Related Commitments and Contractual Obligations

Nicolet is party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. At December 31, 2021, interest rate lock commitments to originate residential mortgage loans held for sale of $50 million (included in the commitments to extend credit) and forward commitments to sell residential mortgage loans held for sale of $1 million are considered derivative instruments. Further information and discussion of these commitments is included in Note 14, “Commitments and Contingencies” of the Notes to Consolidated Financial Statements, under Part II, Item 8.

The table below outlines the principal amounts and timing of Nicolet’s contractual obligations. The amounts presented below exclude amounts due for interest, if applicable, and include any unamortized premiums / discounts or other similar carrying value adjustments. As of December 31, 2021, Nicolet had the following contractual obligations. Further discussion of the nature of each obligation is included in the referenced note of the Notes to Consolidated Financial Statements, under Part II, Item 8.

Critical Accounting Estimates

The consolidated financial statements of Nicolet are prepared in conformity with U.S. generally accepted accounting principles (“GAAP”) and follow general practices within the industry in which it operates. This preparation requires management to make estimates, assumptions and judgments that affect the amounts reported in the consolidated financial statements and accompanying notes. These estimates, assumptions and judgments are based on information available as of the date of the consolidated financial statements; accordingly, as this information changes, actual results could differ from the estimates, assumptions and judgments reflected in the consolidated financial statements. Certain policies inherently have a greater reliance on the use of estimates,

assumptions and judgments and, as such, have a greater possibility of producing results that could be materially different than originally reported. Estimates that are particularly susceptible to significant change include the valuation of loan acquisition transactions, as well as the determination of the allowance for credit losses and income taxes and, therefore, are critical accounting policies. In addition to the discussion that follows, the accounting policies related to these estimates are further described in Note 1, “Nature of Business and Significant Accounting Policies,” in the Notes to Consolidated Financial Statements, under Part II, Item 8.

Business Combinations and Valuation of Loans Acquired in Business Combinations

We account for acquisitions under Financial Accounting Standards Board (“FASB”) ASC Topic 805, Business Combinations, which requires the use of the acquisition method of accounting. Assets acquired and liabilities assumed in a business combination are recorded at the estimated fair value on their purchase date. As provided for under GAAP, management has up to 12 months following the date of the acquisition to finalize the fair values of acquired assets and assumed liabilities, where it was not possible to estimate the acquisition date fair value upon consummation. Management finalized the fair values of acquired assets and assumed liabilities within this 12-month period and management currently considers such values to be the Day 1 Fair Values for the acquisition transactions.

In particular, the valuation of acquired loans involves significant estimates, assumptions and judgment based on information available as of the acquisition date. Loans acquired in a business combination transaction are evaluated either individually or in pools of loans with similar characteristics; including consideration of a credit component. A number of factors are considered in determining the estimated fair value of purchased loans including, among other things, the remaining life of the acquired loans, estimated prepayments, estimated loss ratios, estimated value of the underlying collateral, estimated holding periods, contractual interest rates compared to market interest rates, and net present value of cash flows expected to be received.

Allowance for Credit Losses - Loans

Management’s evaluation process used to determine the appropriateness of the ACL-Loans is subject to the use of estimates, assumptions, and judgment. The evaluation process involves gathering and interpreting many qualitative and quantitative factors which could affect probable credit losses. Because interpretation and analysis involves judgment, current economic or business conditions can change, and future events are inherently difficult to predict, the anticipated amount of estimated credit losses and therefore the appropriateness of the ACL-Loans could change significantly. Effective January 1, 2020, the Company changed its methodology for accounting for the allowance for credit losses-loans due to the adoption of a new accounting standard, which requires use of a lifetime expected credit losses model versus the historical incurred credit losses model. See Note 1, “Nature of Business and Significant Accounting Policies,” in the Notes to Consolidated Financial Statements, under Part II, Item 8 for the impact of this change on accounting policies.

The allocation methodology applied by Nicolet is designed to assess the appropriateness of the ACL-Loans and includes allocations for individually evaluated credit-deteriorated loans and loss factor allocations for all remaining loans, with a component primarily based on historical loss rates and a component primarily based on other qualitative and environmental factors. The methodology includes evaluation and consideration of several factors, including but not limited to: management’s ongoing review and grading of the loan portfolio, evaluation of facts and issues related to specific loans, consideration of historical loan loss and delinquency experience on each portfolio segment, trends in past due and nonaccrual loans, the risk characteristics of specific loans or various loan segments, changes in the size and character of the loan portfolio, concentrations of loans to specific borrowers or industries, the fair value of underlying collateral, existing economic conditions, and other qualitative and quantitative factors which could affect expected credit losses. In addition, with adoption of CECL in 2020, the model also now considers reasonable and supportable forecasts to assess the collectability of future cash flows. While management uses the best information available to make its evaluation, future adjustments to the ACL-Loans may be necessary if there are significant changes in economic conditions (both existing and forecast) or circumstances underlying the collectability of loans. Because each of the criteria used is subject to change, the allocation of the ACL-Loans is made for analytical purposes and is not necessarily indicative of the trend of future credit losses in any particular loan category. The ACL-Loans is available to absorb losses from any segment of the loan portfolio. Management believes the ACL-Loans is appropriate at December 31, 2021. The allowance analysis is reviewed by the board of directors on a quarterly basis in compliance with regulatory requirements.

Consolidated net income and stockholders’ equity could be affected if management’s estimate of the ACL-Loans necessary to cover expected credit losses is subsequently materially different, requiring a change in the level of provision for credit losses to be recorded. While management uses currently available information to recognize expected credit losses on loans, future adjustments to the ACL-Loans may be necessary based on newly received appraisals, updated commercial customer financial statements, rapidly deteriorating customer cash flow, and changes in economic conditions or forecasts that affect Nicolet’s customers. As an integral part of their examination process, federal regulatory agencies also review the ACL-Loans. Such agencies may require additions to the ACL-Loans or may require that certain loan balances be charged-off or downgraded into classified loan categories when their credit evaluations differ from those of management based on their judgments about information available to them at the time of their examination.

Income Taxes

The assessment of income tax assets and liabilities involves the use of estimates, assumptions, interpretation, and judgment concerning certain accounting pronouncements and federal and state tax codes. There can be no assurance that future events, such as court decisions or positions of federal and state taxing authorities, will not differ from management’s current assessment, the impact of which could be significant to the consolidated results of operations and reported earnings.

Nicolet files a consolidated federal income tax return and a combined state income tax return (both of which include Nicolet and its wholly owned subsidiaries). Accordingly, amounts equal to tax benefits of those companies having taxable federal losses or credits are reimbursed by the companies that incur federal tax liabilities. Amounts provided for income tax expense are based on income reported for financial statement purposes and do not necessarily represent amounts currently payable under tax laws. Deferred income tax assets and liabilities are computed quarterly for differences between the financial statement and tax bases of assets and liabilities that will result in taxable or deductible amounts in the future based on enacted tax law rates applicable to the periods in which the differences are expected to affect taxable income. As changes in tax laws or rates are enacted, deferred tax assets and liabilities are adjusted through provision for income tax expense. Valuation allowances are established when it is more likely than not that a portion of the full amount of the deferred tax asset will not be realized. In assessing the ability to realize deferred tax assets, management considers the scheduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies. Nicolet may also recognize a liability for unrecognized tax benefits from uncertainty in income taxes. Unrecognized tax benefits represent the differences between a tax position taken or expected to be taken in a tax return and the benefit recognized and measured in the financial statements. Penalties related to unrecognized tax benefits are classified as income tax expense.

Notes to Consolidated Financial Statements

NOTE 1. NATURE OF BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES

Nature of Banking Activities and Subsidiaries: Nicolet Bankshares, Inc. (the “Company” or “Nicolet”) was incorporated on April 5, 2000, to serve as the holding company and sole shareholder of Nicolet National Bank (the “Bank”). The Bank opened for business on November 1, 2000. Since its opening in late 2000, Nicolet has supplemented its organic growth with branch purchase and acquisition transactions. See Note 2 for additional information on the Company’s recent acquisitions.

At December 31, 2021, the Company had three wholly owned subsidiaries, the Bank, Nicolet Advisory Services, LLC (“Nicolet Advisory”), and Nicolet Insurance Services, LLC (“Nicolet Insurance”). At December 31, 2021, the Bank wholly owns an investment subsidiary based in Nevada, a subsidiary that provides a web-based investment management platform for financial advisor trades and related activity, and an entity that owns the building in which Nicolet is headquartered, Nicolet Joint Ventures, LLC (the “JV”). The JV was owned 50% by a real estate development and investment firm (the “Firm”) through the JV until late 2020 when the Bank became the 100% owner and sole managing member of the JV. The Firm is considered a related party, as one of its principals is a Board member and shareholder of the Company. See Note 15 for additional related party disclosures, including details of the 50% interest purchased from the Firm.

Nicolet Advisory is a registered investment advisor subsidiary that provides brokerage and investment advisory services to customers. In late 2020, to improve process efficiencies and organizational structure, the Company dissolved its wholly owned subsidiary, Brookfield Investment Partners, LLC, which provided limited investment services (transactional and strategy) to a few smaller banks, and Nicolet Advisory assumed those additional investment services contracts. Nicolet Insurance, acquired in 2021, was formed to facilitate the delivery of a crop insurance product associated with Nicolet’s agricultural lending.

Principles of Consolidation: The consolidated financial statements of the Company include the accounts of its subsidiaries. The JV underlies the noncontrolling interest reflected in the consolidated financial statements until late 2020 when the Bank purchased the remaining interest as discussed in Note 1 above under Nature of Banking Activities and Subsidiaries. The consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and conform to general practices within the banking industry. All significant intercompany accounts and transactions have been eliminated in the consolidated financial statements. Results of operations of companies purchased, if any, are included from the date of acquisition.

Operating Segment: The consolidated income of the Company is derived principally from the Bank, which conducts lending (primarily commercial and agricultural-based loans, as well as residential and consumer loans) and deposit gathering (including other banking- and deposit-related products and services, such as ATMs, safe deposit boxes, check cashing, wires, and debit cards) to businesses, consumers and governmental units principally in its trade area of northeast and central Wisconsin, and northern Michigan and the upper peninsula of Michigan, trust services, brokerage services (delivered through the Bank and Nicolet Advisory), and the support to deliver, fund and manage all such banking and wealth management services to its customer base. The individual contribution from wealth management was not significant to the consolidated balance sheet or net income for 2021, 2020, or 2019. While the chief operating decision makers monitor the revenue streams of the various products and services, and evaluate costs, balance sheet positions and quality, all such products, services and activities are directly or indirectly related to the business of community banking, with no regular, formal or material segment delineations. Operations are managed and financial performance is evaluated on a company-wide basis, and accordingly, all the financial service operations are considered by management to be aggregated in one reportable operating segment.

Use of 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 credit losses, valuation of loans in acquisition transactions, useful lives for depreciation and amortization, fair value of financial instruments, 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 credit losses-loans, 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,

Notes to Consolidated Financial Statements

although management does not generally believe such differences would materially affect the consolidated financial statements in any individual reporting period presented.

Business Combinations: The Company accounts for business combinations under the acquisition method of accounting in accordance with Accounting Standards Codification (“ASC”) 805, Business Combinations (“ASC 805”). The Company recognizes the full fair value of the assets acquired and liabilities assumed and immediately expenses transaction costs. If the amount of consideration exceeds the fair value of assets purchased less the fair value of liabilities assumed, goodwill is recorded. Alternatively, if the amount by which the fair value of assets purchased exceeds the fair value of liabilities assumed and consideration paid, a gain (“bargain purchase gain”) is recorded. Fair values are subject to refinement for up to one year after the closing date of an acquisition as information relative to closing date fair values becomes available. Results of operations of the acquired business are included in the statements of income from the effective date of the acquisition. Additional information regarding recent acquisitions is provided in Note 2.

Cash and Cash Equivalents: For purposes of the consolidated statements of cash flows, cash and cash equivalents include cash and due from banks, interest-earning deposits in other banks with original maturities of less than 90 days, if any, and federal funds sold. The Bank maintains amounts in due from banks which, at times, may exceed federally insured limits. Management monitors these correspondent relationships. The Bank has not experienced any losses in such accounts. The Bank may have restrictions on cash and due from banks as it is required to maintain certain vault cash and reserve balances with the Federal Reserve Bank to meet specific reserve requirements. At December 31, 2021 and 2020, no reserve balance was required with the Federal Reserve Bank as the Federal Reserve’s board authorized a reduction to the reserve requirement ratios to 0% effective March 26, 2020 to provide monetary stimulus in response to the economic disruptions resulting from the pandemic. In addition, cash and cash equivalents includes restricted cash of $1.9 million pledged as collateral on an interest rate swap at both December 31, 2021 and 2020.

Securities Available for Sale: Securities are classified as AFS on the consolidated balance sheets at the time of purchase and include those securities that the Company intends to hold for an indefinite period of time, but not necessarily to maturity. Any decision to sell a security classified as AFS would be based on various factors, including significant movements in interest rates, changes in the maturity mix of the Company’s assets and liabilities, liquidity needs, regulatory capital considerations, and other similar factors. Securities classified as AFS are carried at fair value, with unrealized gains or losses, net of related deferred income taxes, reported as increases or decreases in accumulated other comprehensive income. Realized gains or losses on sales of securities AFS (using the specific identification method) are included in the consolidated statements of income under asset gains (losses), net. Premiums and discounts are amortized or accreted into interest income over the estimated life of the related securities using the effective interest method.

Management evaluates securities AFS in unrealized loss positions on a quarterly basis to determine whether the decline in fair value below the amortized cost basis (impairment) is due to credit-related factors or noncredit-related factors. In making this evaluation, management considers the extent to which the fair value has been less than cost, the financial condition and near-term prospects of the issuer, and the intent and ability of the Company to hold the security for a period of time sufficient to allow for any anticipated recovery in fair value. Any impairment that is not credit-related is recognized in other comprehensive income, net of related deferred income taxes. Credit-related impairment is recognized as an allowance for credit losses (“ACL”) on the balance sheet based on the amount by which the amortized cost basis exceeds the fair value, with a corresponding charge to net income. Both the ACL and charge to net income may be reversed if conditions change. However, if the Company intends to sell an impaired AFS security or more likely than not will be required to sell such a security before recovering its amortized cost basis, the entire impairment must be recognized in net income with a corresponding adjustment to the security’s amortized cost basis rather than through the establishment on an ACL. See Note 3 for additional disclosures on AFS securities.

Securities Held to Maturity: Securities are classified as HTM on the consolidated balance sheets at the time of purchase and include those securities that the Company has both the positive intent and ability to hold to maturity. HTM securities are carried at amortized cost on the consolidated balance sheets. Premiums and discounts are amortized or accreted into interest income over the estimated life of the related securities using the effective interest method.

Management evaluates securities HTM on a quarterly basis to determine whether an ACL is necessary. In making this determination, management considers the facts and circumstances of the underlying investment securities. The ACL for HTM securities, if deemed necessary, evaluates expected credit losses on HTM securities by security type, aggregated by similar risk characteristics, and considers historical credit loss information as adjusted for current conditions and supportable forecasts. See Note 3 for additional disclosures on HTM securities.

Notes to Consolidated Financial Statements

Other Investments: Other investments include equity securities with readily determinable fair values, “restricted” equity securities, and private company securities. At December 31, 2021, other investments included $5.7 million of equity securities which are carried at their readily determinable fair values, $32.1 million of “restricted“ equity securities, and $6.2 million of private company securities. As a member of the Federal Reserve Bank System and the Federal Home Loan Bank (“FHLB”) System, the Bank is required to maintain an investment in the capital stock of these entities. These equity securities are “restricted” in that they can only be sold back to the respective institutions or another member institution at par. Therefore, they are less liquid than other exchange traded equity securities. As no ready market exists for these stocks, and they have no quoted market value, these investments are carried at cost. Also included are investments in other private companies that do not have quoted market prices, which are carried at cost less impairment charges, if any. Management’s evaluation of these other investments for impairment includes consideration of the financial condition and other available relevant information of the issuer.

Loans Held for Sale: Loans originated and intended for sale in the secondary market are carried at the lower of cost or estimated fair value as determined on an aggregate basis and generally consist of current production of certain fixed-rate residential first mortgages. The amount by which cost exceeds fair value is recorded as a valuation allowance and charged to earnings. Changes, if any, in the valuation allowance are included in earnings in the period in which the change occurs. As of December 31, 2021 and 2020, no valuation allowance was necessary. Loans held for sale may be sold servicing retained or servicing released, and are generally sold without recourse. The carrying value of mortgage loans sold with servicing retained is reduced by the amount allocated to the servicing right at the time of sale. Gains and losses on sales of mortgage loans held for sale are included in earnings in mortgage income, net.

Loans – Originated: Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are carried at their amortized cost basis, which is the unpaid principal amount outstanding, net of deferred loan fees and costs, and any direct principal charge-off. The Company made an accounting policy election to exclude accrued interest from the amortized cost basis of loans and report such accrued interest as part of accrued interest receivable and other assets on the consolidated balance sheets.

Interest income is accrued on the unpaid principal balance using the simple interest method. The accrual of interest income on loans is discontinued when, in the opinion of management, there is reasonable doubt as to the borrower’s ability to meet payment of interest or principal when due. Loans are generally placed on nonaccrual status when contractually past due 90 days or more as to interest or principal, though may be placed in such status earlier based on the circumstances. Loans past due 90 days or more may continue on accrual only when they are well secured and/or in process of collection or renewal. When interest accrual is discontinued, all previously accrued but uncollected interest is reversed against current period interest income. Except in very limited circumstances, cash collections on nonaccrual loans are credited to the loan receivable balance and no interest income is recognized on those loans until the principal balance is paid in full. Accrual of interest may be resumed when the customer is current on all principal and interest payments and has been paying on a timely basis for a sustained period of time. See Note 4 for additional information and disclosures on loans.

Loans – Acquired: Loans purchased in acquisition transactions are acquired loans, and are recorded at their estimated fair value on the acquisition date.

Subsequent to January 1, 2020, acquired loans that have evidence of more-than-insignificant deterioration in credit quality since origination are considered purchased credit deteriorated (“PCD”) loans. At acquisition, an estimate of expected credit losses is made for PCD loans. This initial allowance for credit losses is allocated to individual PCD loans and added to the purchase price or acquisition date fair value to establish the initial amortized cost basis of the PCD loans. Any difference between the unpaid principal balance of PCD loans and the amortized cost basis is considered to relate to noncredit factors, resulting in a discount or premium that is amortized to interest income. For acquired loans not deemed PCD loans at acquisition, the difference between the initial fair value mark and the unpaid principal balance are recognized in interest income over the estimated life of the loans. In addition, an initial allowance for expected credit losses is estimated and recorded as provision expense at the acquisition date. The subsequent measurement of expected credit losses for all acquired loans is the same as the subsequent measurement of expected credit losses for originated loans. See Note 4 for additional information and disclosures on loans.

Prior to January 1, 2020, the Company initially classified acquired loans as either purchased credit impaired (“PCI”) loans (i.e., loans that reflect credit deterioration since origination and for which it was probable at acquisition that the Company would be unable to collect all contractually required payments) or purchased non-impaired loans (i.e., “performing acquired loans”). The

NICOLET BANKSHARES, INC.

Notes to Consolidated Financial Statements

Company estimated the fair value of PCI loans based on the amount and timing of expected principal, interest and other cash flows for each loan. The excess of the loan’s contractual principal and interest payments over all cash flows expected to be collected at acquisition was considered an amount that should not be accreted. These credit discounts (“nonaccretable marks”) were included in the determination of the initial fair value for acquired loans; therefore, no allowance for credit losses was recorded at the acquisition date. Differences between the estimated fair values and expected cash flows of acquired loans at the acquisition date that were not credit-based (“accretable marks”) were subsequently accreted to interest income over the estimated life of the loans. Subsequent to the acquisition date for PCI loans, increases in cash flows over those expected at the acquisition date resulted in a move of the discount from nonaccretable to accretable, while decreases in expected cash flows after the acquisition date were recognized through the provision for credit losses.

Allowance for Credit Losses - Loans: The ACL-Loans represents management’s estimate of expected credit losses over the lifetime of the loan based on loans in the Company’s loan portfolio at the balance sheet date. The Company estimates the ACL-Loans based on the amortized cost basis of the underlying loan and has made an accounting policy election to exclude accrued interest from the loan’s amortized cost basis and the related measurement of the ACL-Loans. Estimating the amount of the ACL-Loans is a function of a number of factors, including but not limited to changes in the loan portfolio, net charge-offs, trends in past due and nonaccrual loans, and the level of potential problem loans, all of which may be susceptible to significant change. Actual credit losses, net of recoveries, are deducted from the ACL-Loans. Loans are charged-off when management believes that the collectability of the principal is unlikely. Subsequent recoveries, if any, are credited to the ACL-Loans. A provision for credit losses, which is a charge against income, is recorded to bring the ACL-Loans to a level that, in management’s judgment, is appropriate to absorb expected credit losses in the loan portfolio.

Prior to January 1, 2020, the Company used an incurred loss impairment model to estimate the ACL-Loans. This methodology assessed the overall appropriateness of the allowance for credit losses and included allocations for specifically identified impaired loans and loss factors for all remaining loans, with a component primarily based on historical loss rates and another component primarily based on other qualitative factors. Impaired loans were individually assessed and measured based on the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s observable market price or the fair value of the collateral if the loan was collateral dependent. Loans that were determined not to be impaired were collectively evaluated for impairment, stratified by type and allocated loss ranges based on the Company’s actual historical loss ratios for each strata, and adjustments were also provided for certain environmental and other qualitative factors.

Effective January 1, 2020, the Company uses a current expected credit loss model (“CECL”) to estimate the ACL-Loans. This methodology also considers historical loss rates and other qualitative adjustments, as well as a new forward-looking component that considers reasonable and supportable forecasts over the expected life of each loan. To develop the ACL-Loans estimate under the CECL model, the Company segments the loan portfolio into loan pools based on loan type and similar credit risk elements; performs an individual evaluation of PCD and other credit-deteriorated loans; calculates the historical loss rates for the segmented loan pools; applies the loss rates over the calculated life of the pooled loans; adjusts for forecasted macro-level economic conditions; and determines qualitative adjustments based on factors and conditions unique to Nicolet’s portfolio.

To assess the overall appropriateness of the ACL-Loans, management applies an allocation methodology 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 nonaccrual loans; (v) 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 expected credit losses. Assessing these numerous factors involves significant judgment.

Management allocates the ACL-Loans by pools of risk within each loan portfolio segment. The allocation methodology consists of the following components. First, a specific reserve is established for individually evaluated PCD and other credit-deteriorated loans, which management defines as nonaccrual credit relationships over $250,000, collateral dependent loans, and other loans with evidence of credit deterioration. The specific reserve in the ACL-Loans for these credit deteriorated loans is equal to the aggregate collateral or discounted cash flow shortfall. Next, management allocates the ACL-Loans with historical loss rates by loan segment. The loss factors are measured on a quarterly basis and applied to each loan segment based on current loan balances and projected for their expected remaining life. Management also allocates the ACL-Loans using the qualitative and environmental factors mentioned above. Consideration is given to those current qualitative or environmental factors that are likely to cause estimated credit losses at the evaluation date to differ from the historical loss experience of each loan segment. Lastly, management considers reasonable and

NICOLET BANKSHARES, INC.

Notes to Consolidated Financial Statements

supportable forecasts to assess the collectability of future cash flows. See Note 4 for additional information and disclosures on the ACL-Loans.

Allocations to the ACL-Loans may be made for specific loans but the entire ACL-Loans is available for any loan that, in management’s judgment, should be charged-off or for which an actual loss is realized. The allowance analysis is reviewed by the Board on a quarterly basis in compliance with internal and regulatory requirements.

Credit-Related Financial Instruments: In the ordinary course of business the Company has entered into financial instruments consisting of commitments to extend credit, financial standby letters of credit, and performance standby letters of credit. Financial standby letters of credit are issued specifically to facilitate commerce and typically result in the commitment being drawn on when the underlying transaction is consummated between the customer and the third party, while performance standby letters of credit generally are contingent upon the failure of the customer to perform according to the terms of the underlying contract with the third party. Such financial instruments are recorded in the consolidated financial statements when they are funded. See Note 14 for additional information and disclosures on credit-related financial instruments.

Allowance for Credit Losses - Unfunded Commitments: In addition to the ACL-Loans, the Company has established an allowance for unfunded commitments, included in accrued interest payable and other liabilities on the consolidated balance sheets, representing expected credit losses over the contractual period for which the Company is exposed to credit risk resulting from a contractual obligation to extend credit. The ACL-Unfunded Commitments is maintained at a level that management believes is sufficient to absorb losses arising from unfunded loan commitments, and is determined quarterly based on methodology similar to the methodology for determining the ACL-Loans. See Note 4 for additional information on the ACL-Unfunded Commitments.

Transfers of Financial Assets: Transfers of financial assets, primarily in loan participation activities, are accounted for as sales only when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of the right) to pledge or exchange the transferred assets, and (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity or the ability to unilaterally cause the holder to return assets.

Premises and Equipment: Premises and equipment are stated at cost less accumulated depreciation and amortization. Premises and equipment from acquisitions were recorded at estimated fair value on the respective dates of acquisition. Depreciation is computed on a straight-line basis over the estimated useful lives of the related assets. Leasehold improvements are amortized on a straight-line basis over the shorter of the estimated useful lives of the improvements or the terms of the related leases. Maintenance and repairs are expensed as incurred. See Note 5 for additional information on premises and equipment.

Estimated useful lives of new premises and equipment generally range as follows:

Building and improvements	25 – 40 years
Leasehold improvements	5 – 15 years
Furniture and equipment	3 – 10 years

Operating Leases: The Company accounts for its operating leases in accordance with ASC 842, Leases, which requires lessees to record almost all leases on the balance sheet as a right-of-use (“ROU”) asset and lease liability. The operating lease ROU asset represents the right to use an underlying asset during the lease term (included in accrued interest receivable and other assets on the consolidated balance sheets), while the operating lease liability represents the obligation to make lease payments arising from the lease (included in accrued interest payable and other liabilities on the consolidated balance sheets). 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. See Note 5 for additional information and disclosures on operating leases.

Other Real Estate Owned (“OREO”): OREO acquired through partial or total satisfaction of loans or bank facilities no longer in use are carried at fair value less estimated costs to sell. Any write-down in the carrying value of loans or vacated bank premises at the time of transfer to OREO is charged to the ACL-Loans or to write-down of assets, respectively. OREO properties acquired in conjunction with acquisition transactions were recorded at fair value on the date of acquisition. Any subsequent write-downs to

NICOLET BANKSHARES, INC.

Notes to Consolidated Financial Statements

reflect current fair value, as well as gains or losses on disposition and revenues and expenses incurred to hold and maintain such properties, are treated as period costs. See Note 7 for additional information on OREO.

Goodwill and Other Intangibles: Goodwill represents the excess of the purchase price over the fair value of the net identifiable assets acquired. Goodwill is not amortized but, instead, is subject to impairment tests on at least an annual basis or more frequently if certain events or circumstances occur. Other intangibles include core deposit intangibles (which represent the value of acquired customer core deposit bases) and customer list intangibles. The core deposit intangibles have an estimated finite life, are amortized on an accelerated basis over a 10-year period, and are subject to periodic impairment evaluation. The customer list intangibles have finite lives, are amortized on a straight-line basis to expense over their initial weighted average life of approximately 12 years as of acquisition, and are subject to periodic impairment evaluation. See Note 6 for additional information on goodwill and other intangibles.

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 annual assessments resulted in a $0.8 million impairment charge on goodwill in late 2019 for a change in business strategy, while no other impairment was indicated on the remaining goodwill and other intangibles for 2021 or 2020.

Mortgage Servicing Rights (“MSRs”):  The Company sells originated residential mortgages into the secondary market and retains the right to service the loans sold. A mortgage servicing right asset (liability) is capitalized upon sale of such loans with the offsetting effect recorded as a gain (loss) on sale of loan in earnings (included in mortgage income, net), representing the then-current estimated fair value of future net cash flows expected to be realized for performing the servicing activities.  MSRs when purchased (including MSRs purchased in acquisitions) are initially recorded at their then-estimated fair value.  As the Company has not elected to measure any class of servicing assets under the fair value method, the Company utilizes the amortization method.  MSRs are amortized in proportion to and over the period of estimated net servicing income, with the amortization charged to earnings (included in mortgage income, net). MSRs are carried at the lower of initial capitalized amount, net of accumulated amortization, or estimated fair value, and are included in other assets in the consolidated balance sheets.  Loan servicing fee income for servicing loans is typically based on a contractual percentage of the outstanding principal and is recorded as income when earned (included in mortgage income, net with less material late fees and ancillary fees related to loan servicing).

The Company periodically evaluates its MSRs 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). The value of MSRs is adversely affected when mortgage interest rates decline and mortgage loan prepayments increase.  A valuation allowance is established through a charge to earnings (included in mortgage income, net) to the extent the amortized cost of the MSRs exceeds the estimated fair value by stratification.  If it is later determined that all or a portion of the temporary impairment no longer exists for a stratification, the valuation is reduced through a recovery to earnings, though not beyond the net amortized cost carried.  An other-than-temporary impairment (i.e., recoverability is considered remote when considering interest rates and loan payoff activity) is recognized as a write-down of the MSRs and the related valuation allowance (to the extent a valuation allowance is available) and then against earnings.  A direct write-down permanently reduces the carrying value of the MSRs and valuation allowance, precluding subsequent recoveries.  See Note 6 for additional information on MSRs.

Loan Servicing Rights (“LSRs”):  The Company acquired loan servicing rights in connection with its acquisition of County Bancorp, Inc. (“County”) on December 3, 2021 (see Note 2 for additional information on the County acquisition). The LSRs were recorded at estimated fair value upon acquisition, and are subsequently accounted for utilizing the amortization method. Thus, the LSRs are amortized in proportion to and over the period of estimated net servicing income, with the amortization charged to earnings. The LSRs are assessed for impairment at each reporting date based on estimated fair value. Impairment is determined by stratifying the rights into tranches based on predominant characteristics, such as interest rate, loan type, and investor type. A valuation allowance is established through a charge to earnings to the extent that estimated fair value is less than the carrying amount of the servicing assets for an individual tranche. The valuation allowance is adjusted to reflect changes in the measurement of impairment through either recovery or additions to the valuation allocance, with such changes reported as a component of loan servicing fees on the consolidated statements of income. Fair value in excess of the carrying amount of servicing assets is not recognized. The amortization of loan servicing rights is reflected net of loan servicing fee income.  Loan servicing fee income for

NICOLET BANKSHARES, INC.

Notes to Consolidated Financial Statements

servicing loans is based on a contractual percentage of the outstanding principal and is recorded as income when earned. See Note 6 for additional information on LSRs.

Bank-owned Life Insurance (“BOLI”): The Company owns BOLI on certain executives and employees. BOLI balances are recorded at their cash surrender values. Changes in the cash surrender values and death proceeds exceeding carrying values are included in BOLI income.

Stock-based Compensation: Stock-based payments to employees, including grants of restricted stock or stock options, are valued at fair value of the award on the date of grant and expensed on a straight-line basis as compensation expense over the applicable vesting period. A Black-Scholes model is utilized to estimate the fair value of stock options and the quoted market price of the Company’s stock at the date of grant is used to estimate the fair value of restricted stock awards. See Note 11 for additional information on stock-based compensation.

Income Taxes: The Company files a consolidated federal income tax return and a combined state income tax return (both of which include the Company and its wholly owned subsidiaries). Accordingly, amounts equal to tax benefits of those subsidiaries having taxable federal losses or credits are reimbursed by the subsidiaries that incur federal tax liabilities.

Amounts provided for income tax expense are based on income reported for financial statement purposes and do not necessarily represent amounts currently payable under tax laws. Deferred income tax assets and liabilities are computed quarterly for differences between the financial statement and tax bases of assets and liabilities that will result in taxable or deductible amounts in the future based on enacted tax rates applicable to the periods in which the differences are expected to affect taxable income. As changes in tax laws or rates are enacted, deferred tax assets and liabilities are adjusted through income tax expense. Valuation allowances are established when it is more likely than not that a portion of the full amount of the deferred tax asset will not be realized. In assessing the ability to realize deferred tax assets, management considers the scheduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies.

At acquisition, deferred taxes were evaluated in respect to the acquired assets and assumed liabilities (including the acquired net operating losses), and a net deferred tax asset was recorded. Certain limitations within the provisions of the tax code are placed on the amount of net operating losses which can be utilized as part of acquisition accounting rules and were incorporated into the calculation of the deferred tax asset. In addition, a portion of the fair value discounts on PCD loans which resolved in the first twelve months after the acquisition were disallowed under provisions of the tax code.

The Company may also recognize a liability for unrecognized tax benefits from uncertainty in income tax positions. Unrecognized tax benefits represent the differences between a tax position taken or expected to be taken in a tax return and the benefit recognized and measured in the consolidated financial statements. At December 31, 2021, the Company determined it had no significant uncertainty in income tax positions. Interest and penalties related to unrecognized tax benefits are classified as income tax expense. See Note 13 for additional information on income taxes.

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 common shares adjusted for the dilutive effect of outstanding common stock awards, if any. See Note 20 for additional information on earnings per common share.

Treasury Stock: Treasury stock is accounted for at cost on a first-in-first-out basis. It is the Company’s general practice to cancel treasury stock shares in the same quarter as purchased, and thus, not carry a treasury stock balance.

Comprehensive Income: Accounting principles generally require that recognized revenue, expenses, gains and losses be included in net income. Certain changes in assets and liabilities, such as unrealized gains and losses on securities AFS, are reported in accumulated other comprehensive income, as a separate component of the equity section of the balance sheet. Realized gains or losses are reclassified to current period income. Changes in these items, along with net income, are components of comprehensive income. The Company presents comprehensive income in a separate consolidated statement of comprehensive income.

Revenue Recognition: Accounting principles (Revenue from Contracts with Customers, Topic 606) require that an entity recognize revenue to depict the transfer of promised goods and services to customers in an amount that reflects the consideration to which the

NICOLET BANKSHARES, INC.

Notes to Consolidated Financial Statements

entity expects to be entitled in exchange for those goods and services. The guidance includes a five-step model to apply to revenue recognition, consisting of the following: (1) identify the contract; (2) identify the performance obligation in the contract; (3) determine the transaction price; (4) allocate the transaction price to the performance obligations; and (5) recognize revenue when or as the performance obligation is satisfied. See Note 21 for additional information on revenue recognition.

Future Accounting Pronouncements: In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. This ASU provides optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. It provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The updated guidance is effective for all entities as of March 12, 2020 through December 31, 2022. The Company continues to evaluate the impact of reference rate reform on its consolidated financial statements.

Reclassifications: Certain amounts in the 2020 and 2019 consolidated financial statements have been reclassified to conform to the 2021 presentation.

NOTE 2. ACQUISITIONS

Completed Acquisitions:

County Bancorp, Inc. (“County”): On December 3, 2021, Nicolet completed its merger with County, pursuant to the terms of the Agreement and Plan of Merger dated June 22, 2021 (the “County Merger Agreement”), at which time County merged with and into Nicolet, and Investors Community Bank, the wholly owned bank subsidiary of County, was merged with and into the Bank.

Pursuant to the County Merger Agreement, each share of County common stock issued and outstanding immediately prior to the Effective Time was converted into the right to receive, at the election of the shareholder, either cash of $37.18 or 0.48 shares of Nicolet common stock, subject to proration procedures such that 1,237,000 shares of County common stock were exchanged for cash, and the remaining shares were exchanged for Nicolet common stock. As a result, Nicolet issued approximately 2.4 million shares of Nicolet common stock for stock consideration of $176 million and cash consideration of $48 million, or a total purchase price of $224 million. With the County merger, Nicolet became the premier agriculture lender throughout Wisconsin.

The Company purchased loans through the acquisition of County for which there was, at the date of acquisition, more than insignificant deterioration of credit quality since origination (purchased credit deteriorated loans or “PCD” loans).

The Company accounted for the County acquisition under the acquisition method of accounting, and thus, the financial position and results of operations of County prior to the consummation date were not included in the accompanying consolidated financial statements. The accounting required assets purchased and liabilities assumed to be recorded at their respective estimated fair values at the date of acquisition. The estimated fair value was determined with the assistance of third party valuations, appraisals, and third party advisors. Due to the timing of the merger, the purchase price allocation and estimated fair value measurements remain preliminary. Goodwill arising as a result of the County acquisition is not deductible for tax purposes. Management will continue to review the estimated fair values and expects to finalize its analysis of the acquired assets and assumed liabilities in the transaction over the next few months, within one year of the merger. Therefore, adjustments to the purchase price allocation and estimated fair value may occur.

Mackinac Financial Corporation (“Mackinac”): On September 3, 2021, Nicolet completed its merger with Mackinac, pursuant to the terms of the Agreement and Plan of Merger dated April 12, 2021 (the “Mackinac Merger Agreement”), at which time Mackinac merged with and into Nicolet, and mBank, the wholly owned bank subsidiary of Mackinac, was merged with and into the Bank.

Notes to Consolidated Financial Statements

Pursuant to the Mackinac Merger Agreement, Mackinac shareholders received fixed consideration of 0.22 shares of Nicolet common stock and $4.64 in cash for each share of Mackinac common stock owned (approximating 20% in cash and 80% in stock), resulting in the issuance of 2.3 million shares of Nicolet common stock for stock consideration of $180 million and cash consideration of $49 million, or a total purchase price of $229 million. The Mackinac merger expands Nicolet prominently into Northern Michigan and the Upper Peninsula of Michigan, and adds to Nicolet’s presence in upper northeastern Wisconsin.

A summary of the assets acquired and liabilities assumed in the Mackinac transaction, as of the acquisition date, including the preliminary purchase price allocation was as follows.

Summary Unaudited Pro Forma Information: The following unaudited pro forma information is presented for illustrative purposes only, and gives effect to the acquisitions of County and Mackinac as if the acquisitions had occurred on January 1, 2019, the beginning of the earliest period presented. The pro forma information should not be relied upon as being indicative of the historical results of operations the companies would have had if the acquisitions had occurred before such periods or the future results of operations that the companies will experience as a result of the mergers. The pro forma information, although helpful in illustrating the financial characteristics of the combined company under one set of assumptions, does not reflect the benefits of expected cost savings, opportunities to earn additional revenue, the impact of restructuring and merger-related expenses, or other factors that may result as a consequence of the mergers and, accordingly, does not attempt to predict or suggest future results.

Advantage Community Bancshares, Inc. (“Advantage”): On August 21, 2020, Nicolet completed its merger with Advantage, pursuant to the terms of the definitive merger agreement dated March 2, 2020, whereby Advantage merged with and into Nicolet, and Advantage Community Bank, the wholly owned bank subsidiary of Advantage, was merged with and into the Bank. Advantage’s four branches in Dorchester, Edgar, Mosinee, and Wausau opened as Nicolet National Bank branches on August 24, 2020, expanding our presence in Central Wisconsin and the Wausau area. Due to the small size of the transaction, terms of the all-cash deal were not disclosed.

Upon consummation, Advantage added total assets of approximately $172 million (representing 4% of Nicolet’s then pre-merger asset size), loans of $88 million, deposits of $141 million, core deposit intangible of $1 million, and goodwill of $12 million.

Choice Bancorp, Inc. (“Choice”): On November 8, 2019, the Company consummated its merger with Choice, pursuant to the terms of the Agreement and Plan of Merger dated June 26, 2019, (the “Choice Merger Agreement”), whereby Choice (at 12% of Nicolet’s then pre-merger asset size) was merged with and into Nicolet, and Choice Bank, the wholly owned bank subsidiary of Choice, was merged with and into the Bank. The system integration was completed, and the two branches of Choice opened on November 12, 2019, as Nicolet National Bank branches, expanding its presence in the Oshkosh marketplace. The Company closed its legacy Oshkosh location concurrently with the consummation of the Choice merger.

The purpose of the merger was to continue Nicolet’s interest in strategic growth, consistent with its plan to improve profitability through efficiency, leverage the strengths of each bank across the combined customer base, and add shareholder value. With the merger, Nicolet became the leading community bank to serve the Oshkosh marketplace.

Pursuant to the Choice Merger Agreement, the final purchase price consisted of issuing 1,184,102 shares of the Company’s common stock (given the final stock-for-stock exchange ratio of 0.497, and not exchanging the Choice shares owned by the Company immediately prior to the time of the merger), for common stock consideration of $79.8 million (based on $67.39 per share, the volume weighted average closing price of the Company’s common stock over the preceding 30 trading day period) plus cash consideration of $1.7 million. Approximately $0.2 million in direct stock issuance costs for the merger were incurred and charged against additional paid-in capital.

Upon consummation, Choice added $457 million in assets, including $348 million in loans, $289 million in deposits, $1.7 million in core deposit intangible, and $45 million of goodwill. The Company accounted for the transaction under the acquisition method of accounting, and thus, the financial position and results of operations of Choice prior to the consummation date were not included in the accompanying consolidated financial statements. The accounting required assets purchased and liabilities assumed to be recorded at their respective estimated fair values at the date of acquisition.

Terminated Acquisition:

Commerce Financial Holdings, Inc. (“Commerce”): On February 17, 2020, Nicolet entered into a definitive merger agreement (“Merger Agreement”) with Commerce pursuant to which Nicolet would acquire Commerce and its wholly owned bank subsidiary, Commerce State Bank. On May 18, 2020, Nicolet and Commerce announced a mutual agreement to terminate their Merger Agreement. Nicolet paid Commerce $0.5 million and surrendered its $0.1 million of Commerce common stock.

NOTE 3.  INVESTMENT SECURITIES

Investment securities are classified as AFS or HTM on the consolidated balance sheets at the time of purchase. AFS securities include those securities that the Company intends to hold for an indefinite period of time, but not necessarily to maturity, and are carried at fair value on the consolidated balance sheets. HTM securities include those securities which the Company has both the positive intent and ability to hold to maturity, and are carried at amortized cost on the consolidated balance sheets. See Note 1 for the Company’s accounting policy on investment securities.

During 2021, the Company purchased approximately $500 million of U.S. government agency securities of varying yields and durations, which were classified as HTM, to re-invest a portion of excess cash liquidity. In addition, a portion of the investment securities acquired with County and Mackinac were designated as HTM at acquisition. The amortized cost and fair value of securities available for sale and held to maturity are summarized as follows.

Notes to Consolidated Financial Statements

Investment securities with a carrying value of $277 million and $146 million as of December 31, 2021 and 2020, respectively, were pledged as collateral on public deposits and for other purposes as required or permitted by law. Accrued interest on investment securities totaled $4.6 million and $2.3 million at December 31, 2021 and 2020, respectively, and is included in accrued interest receivable and other assets on the consolidated balance sheets.

Management evaluates securities AFS in unrealized loss positions on a quarterly basis to determine whether the decline in fair value below the amortized cost basis (impairment) is due to credit-related factors or noncredit-related factors. The Company does not consider its securities AFS with unrealized losses to be attributable to credit-related factors, as the unrealized losses in each category have occurred as a result of changes in noncredit-related factors such as changes in interest rates, market spreads and market conditions subsequent to purchase, not credit deterioration. Furthermore, the Company does not have the intent to sell any of these securities AFS and believes that it is more likely than not that we will not have to sell any such securities before a recovery of cost. As of December 31, 2021 and 2020, no allowance for credit losses on securities AFS was recognized. There were no other-than-temporary impairment charges recognized in earnings on securities AFS during 2019.

Management evaluates securities HTM on a quarterly basis to determine whether an allowance for credit losses is necessary. In making this determination, management considers the facts and circumstances of the underlying investment securities. The U.S. government agency securities include U.S. Treasury Notes which are guaranteed by the U.S. government. For the state, county and municipal securities, management considers issuer bond ratings, historical loss rates by bond ratings, whether issuers continue to make timely principal and interest payments per the contractual terms of the investment securities, internal forecasts, and whether or not such investment securities provide insurance, other credit enhancement, or are pre-refunded by the issuers. For the mortgage-backed securities, all such securities were issued by U.S. government agencies and corporations, which are currently explicitly or implicitly guaranteed by the U.S. government and have a long history of no credit losses. Therefore, management determined no allowance for credit losses was necessary for the securities HTM.

The following tables present gross unrealized losses and the related estimated fair value of investment securities for which an allowance for credit losses has not been recorded, aggregated by investment category and the length of time the individual securities have been in a continuous unrealized loss position.

The amortized cost and fair value of investment securities 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.

Allowance for Credit Losses-Loans:

The majority 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 credit losses - loans was as follows.

The ACL-Loans was estimated using the current expected credit loss model. See Note 1 for the Company’s accounting policy on loans and the allowance for credit losses.

Allowance for Credit Losses-Unfunded Commitments:

In addition to the ACL-Loans, the Company has established an ACL-Unfunded Commitments of $2.4 million at December 31, 2021, classified in accrued interest payable and other liabilities on the consolidated balance sheets. See Note 1 for the Company’s accounting policy on the allowance for credit losses-unfunded commitments.

Provision for Credit Losses:

The provision for credit losses is determined by the Company as the amount to be added to the ACL loss accounts for various types of financial instruments (including, loans, investment securities, and off-balance sheet credit exposures) after net charge-offs have been deducted to bring the ACL to a level that, in management’s judgment, is necessary to absorb expected credit losses over the lives of the respective financial instruments.

Collateral Dependent Loans:

A loan is considered to be collateral dependent when, based upon management’s assessment, the borrower is experiencing financial difficulty and repayment is expected to be provided substantially through the operation or sale of the collateral. For collateral dependent loans, expected credit losses are based on the fair value of the collateral at the balance sheet date, with consideration for estimated selling costs if satisfaction of the loan depends on the sale of the collateral. The following table presents collateral dependent loans by portfolio segment and collateral type, including those loans with and without a related allowance allocation.

An internal loan review function rates loans using a grading system based on different risk categories. Loans with a Substandard grade are considered to have a greater risk of loss and may be assigned allocations for loss based on specific review of the weaknesses observed in the individual credits. Such loans are monitored by the loan review function to help ensure early identification of any deterioration. 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.

NICOLET BANKSHARES, INC.

Notes to Consolidated Financial Statements

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.

Troubled Debt Restructurings:

Loans are considered troubled debt restructurings if concessions have been granted to borrowers who are experiencing financial difficulties. The following table presents the loan composition of nonaccrual and performing TDRs.

Depreciation and amortization expense was $5.0 million in 2021, $4.4 million in 2020, and $3.8 million in 2019. The Company and certain of its subsidiaries are obligated under non-cancelable operating leases for facilities, certain of which provide for rental adjustments based upon increases in cost of living adjustments and other indices. Rent expense under leases totaled $1.3 million in 2021, $1.0 million in 2020, and $1.2 million in 2019. See Note 1 for the Company’s accounting policy on premises and equipment.

Nicolet leases space under non-cancelable operating lease agreements for certain bank branch facilities with remaining lease terms of 1 to 10 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. See Note 1 for the Company’s accounting policy on operating leases.

During 2021, the Company closed fifteen branch locations (ten acquired with Mackinac and the remainder legacy Nicolet branches) as part of its branch optimization strategy to better align with customer actions. The 2021 closures resulted in accelerated depreciation of $0.9 million (recorded to occupancy, equipment and office expense). During 2020, the Company permanently closed

NICOLET BANKSHARES, INC.

Notes to Consolidated Financial Statements

eight branch locations (five owned locations and three leased locations) given changing customer needs, partly from the pandemic. The 2020 closures resulted in accelerated depreciation of $0.5 million, a $1.0 million lease termination charge (recorded to other expense), and a $0.5 million write-down upon transfer of the owned locations to OREO (recorded to asset gains (losses), net). During 2019, a $0.7 million lease termination charge was recorded to other expense due to the closure of a branch, concurrent with the consummation date of the Choice merger.

NOTE 6. GOODWILL AND OTHER INTANGIBLES AND 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. Management continues to consider the ongoing impacts of the COVID-19 pandemic and related economic uncertainty on the valuation of our franchise value, stability of deposits, and of the wealth client base, underlying our goodwill, core deposit intangibles, and customer list intangibles, and determined no impairments were indicated. A summary of goodwill and other intangibles was as follows.

Goodwill: Goodwill is not amortized but, instead, is subject to impairment tests on at least an annual basis or more frequently if certain events or circumstances occur. During 2021, goodwill increased due to the acquisitions of Mackinac and County, while during 2020 goodwill increased due to the Advantage acquisition. See Note 1 for the Company’s accounting policy for goodwill and see Note 2 for additional information on the Company’s acquisitions.

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 stratification based on the risk characteristics of the underlying loans (predominantly loan type and note interest rate). See Note 1 for the Company’s accounting policy for MSRs, see Note 2 for additional information on the Company’s acquisitions, and see Note 18 for additional information on the fair value of the MSR asset.

Loan servicing rights: The Company acquired an LSR asset in connection with its acquisition of County on December 3, 2021 (see Note 2 for additional information on the County acquisition). The LSR asset was $20 million at December 31, 2021, and related to $794 million of unpaid principal balances of loans serviced for others. The LSR asset will be amortized over the estimated remaining loan service period as the Company does not expect to add new loans to this servicing portfolio. See Note 1 for the Company’s accounting policy for LSRs and see Note 18 for additional information on the fair value of the LSR asset.

The following table shows the estimated future amortization expense for amortizing intangible assets and the servicing assets. The projections are based on existing asset balances, the current interest rate environment and prepayment speeds as of December 31, 2021. 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.

Junior Subordinated Debentures: Each of the junior subordinated debentures was issued to an underlying statutory trust (the “statutory trusts”), which issued trust preferred securities and common securities and used the proceeds from the issuance of the common and the trust preferred securities to purchase the junior subordinated debentures of the Company. The debentures represent the sole asset of the statutory trusts. All of the common securities of the statutory trusts are owned by the Company. The statutory trusts are not included in the consolidated financial statements. The net effect of all the documents entered into with respect to the trust preferred securities is that the Company, through payments on its debentures, is liable for the distributions and other payments required on the trust preferred securities. Interest on all debentures is current. Any applicable discounts (initially recorded to carry an acquired debenture at its then estimated fair value) are being accreted to interest expense over the remaining life of the debenture. All the junior subordinated debentures are currently callable and may be redeemed in part or in full, at par, plus any accrued but unpaid interest. At December 31, 2021 and 2020, $37 million and $24 million, respectively, of trust preferred securities qualify as Tier 1 capital.

Subordinated Notes (the “Notes”): In July 2021, the Company completed the private placement of $100 million in fixed-to-floating rate subordinated notes due in 2031, with a fixed annual rate of 3.125% for the first five years, and will reset quarterly thereafter to the then current three-month Secured Overnight Financing Rate (“SOFR”) plus 237.5 basis points. The Notes due in 2031 are redeemable beginning July 15, 2026 and quarterly thereafter on any interest payment date.

In December 2021, Nicolet assumed two subordinated note issuances at a premium as the result of the County acquisition. One issuance was $30 million in fixed-to-floating rate subordinated notes due in 2028, with a fixed annual interest rate of 5.875% for the first five years, and will reset quarterly thereafter to the then current three-month LIBOR plus 2.88%. The second issuance was $22 million in fixed-to-floating rate subordinated notes due in 2030, with a fixed annual interest rate of 7.00% for the first five years, and will reset quarterly thereafter to the then current SOFR plus 687.5 basis points. The Notes due in 2028 are redeemable beginning June 1, 2023, and quarterly thereafter on any interest payment date, while the Notes due in 2030 are redeemable beginning June 30, 2025, and quarterly thereafter on any interest payment date. All Notes qualify as Tier 2 capital for regulatory purposes.

NOTE 10. EMPLOYEE AND DIRECTOR BENEFIT PLANS

The Company sponsors two deferred compensation plans, one for certain key management employees and another for directors. Under the management plan, employees designated by the Board of Directors may elect to defer compensation and the Company may at its discretion make nonelective contributions on behalf of one or more eligible plan participants. Upon retirement, termination of employment or at their election, the employee shall become entitled to receive the deferred amounts plus earnings thereon. The liability for the cumulative employee contributions and earnings thereon at December 31, 2021 and 2020 totaled approximately $2.0 million and $1.5 million, respectively, and is included in other liabilities on the consolidated balance sheets. The Company recorded discretionary contributions totaling $5.7 million and $1.4 million during 2021 and 2020, respectively, to selected recipients, which vested immediately and were fully expensed upon grant.

Under the director plan, participating directors may defer up to 100% of their Board compensation towards the purchase of Company common stock at market prices on a quarterly basis that is held in a Rabbi Trust and distributed when each such participating director ends his or her board service. During 2021 and 2020, the director plan purchased 1,018 and 2,561 shares of Company common stock valued at approximately $73,000 and $149,000, respectively. Common stock valued at approximately $366,000 (and representing 4,737 shares) and $20,157 (and representing 282 shares) was distributed to past directors during 2021 and 2020, respectively. The common stock outstanding and the related director deferred compensation liability are offsetting components of the Company’s equity in the amount of $1.1 million at December 31, 2021 and $1.2 million at December 31, 2020 representing 27,762 shares and 31,481 shares, respectively.

The Company sponsors a 401(k) savings plan under which eligible employees may choose to save up to 100% of salary compensation on either a pre-tax or after-tax basis, subject to certain IRS limits. Under the plan, the Company matches 100% of participating employee contributions up to 6% of the participant’s eligible compensation. The Company contribution vests over five years. The Company can make additional annual discretionary profit sharing contributions, as determined by the Board of Directors. During 2021, 2020 and 2019, the Company’s 401(k) expense was approximately $2.5 million (including a $0.5 million profit

NOTE 11. 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. The Company’s stock-based compensation plans at December 31, 2021 are described below.

2011 Long-Term Incentive Plan (“2011 LTIP”): The Company’s 2011 LTIP, as subsequently amended with shareholder approval, has reserved 3,000,000 shares of the Company’s common stock for potential stock-based awards. This plan provides for certain stock-based awards such as, but not limited to, stock options, stock appreciation rights and restricted common stock, as well as cash performance awards. As of December 31, 2021, approximately 0.9 million shares were available for grant under this plan.

2002 Stock Incentive Plan: The Company’s 2002 Stock Incentive Plan, as subsequently amended with shareholder approval, reserved shares of the Company’s common stock for potential stock options. This plan became fully utilized in 2012 and no further awards may be granted under this plan.

Acquired Equity Incentive Plan: In 2016, the Company assumed sponsorship of an equity incentive plan of an acquired company to allow for that company’s already granted awards that became exercisable upon acquisition to be honored. No further awards may be granted under this assumed plan.

Stock option grants generally will expire ten years after the date of grant, have an exercise price equal to the Company’s closing stock price on the date of grant, and will become exercisable based upon vesting terms determined by the committee. Restricted stock grants generally are issued at the Company’s closing stock price on the date of grant, are restricted as to transfer, but are not restricted as to dividend payments or voting rights, and the transfer restrictions lapse over time, depending upon vesting terms provided for in the grant and contingent upon continued employment.

A Black-Scholes model is utilized to estimate the fair value of stock option grants. See Note 1 for the Company’s accounting policy on stock-based compensation. The weighted average assumptions used in the model for valuing stock option grants were as follows.

	2021			2020			2019
Dividend yield	—		%	—		%	—		%
Expected volatility	30		%	25		%	25		%
Risk-free interest rate	1.19		%	1.35		%	1.75		%
Expected average life	7 years			7 years			7 years
Weighted average per share fair value of options	$	26.33		$	20.55		$	21.30

The Company recognized $6.6 million, $5.3 million and $4.8 million of stock-based compensation expense (included in personnel on the consolidated statements of income) during the years ended December 31, 2021, 2020, and 2019, respectively, associated with its common stock awards granted to officers and employees. In addition, during 2021, 2020, and 2019, the Company recognized approximately $0.8 million, $0.4 million, and $0.3 million, respectively, of director expense (included in other expense on the consolidated statements of income) for restricted stock grants with immediate vesting to non-employee directors totaling 9,875 shares in 2021, 7,950 shares in 2020, and 4,257 shares in 2019. As of December 31, 2021, there was approximately $16.7 million of unrecognized compensation cost related to equity award grants. The cost is expected to be recognized over the remaining vesting period of approximately four years. The Company recognized a tax benefit of approximately $0.6 million, $0.8 million, and $2.3 million for the years ended December 31, 2021, 2020, and 2019 respectively, for the tax impact of stock option exercises and vesting of restricted stock.

NOTE 12. STOCKHOLDERS' EQUITY

The Board of Directors has authorized the repurchase of Nicolet’s outstanding common stock through its common stock repurchase program. During 2021, $61 million was utilized to repurchase and cancel over 793,000 common shares at a weighted average price of $77.50. As of December 31, 2021, there remained $69 million authorized under the repurchase program to be utilized from time-to-time to repurchase common shares in the open market, through block transactions or in private transactions. See Note 15 for additional information on common stock repurchases in private transactions with related parties.

On September 3, 2021, in connection with its acquisition of Mackinac, the Company issued 2,337,230 shares of its common stock for stock consideration valued at $180 million plus cash consideration of $49 million. Approximately $0.4 million in direct stock issuance costs for the merger were incurred and charged against additional paid-in capital. See Note 2 for additional information on the Mackinac acquisition.

A valuation allowance is required if it is more likely than not that some portion of the deferred tax asset will not be realized. At December 31, 2021 and 2020, no valuation allowance was determined to be necessary.

At December 31, 2021, the Company had a federal and state net operating loss carryforward of $11.9 million and $18.8 million, respectively. The entire federal and state net operating loss carryforwards were the result of the Company’s acquisitions. The federal and state net operating loss carryovers resulting from the acquisitions have been included in the IRC section 382 limitation calculation and are being limited to the overall amount expected to be realized.

NOTE 14. COMMITMENTS AND CONTINGENCIES

The Company is party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit, financial guarantees, and standby letters of credit. Such commitments may involve, to varying degrees, elements of credit risk in excess of amounts recognized on the consolidated balance sheets. The Company’s exposure to credit loss in the event of nonperformance by the other party to the financial instruments for commitments to extend credit and standby letters of credit is represented by the contractual amount of those instruments. The Company uses the same credit policies in making commitments and issuing letters of credit as they do for on-balance sheet instruments. See Note 1 for the Company’s accounting policy on commitments, contingencies, and the allowance for credit losses-unfunded commitments and see Note 4 for information on the allowance for credit losses-unfunded commitments.

A summary of the contract or notional amount of the Company’s exposure to off-balance sheet risk was as follows.

(in thousands)	December 31, 2021		December 31, 2020
Commitments to extend credit	$	1,433,881	$	950,287
Financial standby letters of credit	13,562		8,241
Performance standby letters of credit	7,336		8,366

Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commercial-related commitments to extend credit represented 80% and 78% of the total year-end commitments for 2021 and 2020, respectively, and were predominantly commercial lines of credit that carry a term of one year or less. The commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements.

NICOLET BANKSHARES, INC.

Notes to Consolidated Financial Statements

Financial and performance standby letters of credit are conditional commitments issued to guarantee the performance of a customer to a third party. Financial standby letters of credit are issued specifically to facilitate commerce and typically result in the commitment being drawn on when the underlying transaction is consummated between the customer and the third party, while performance standby letters of credit generally are contingent upon the failure of the customer to perform according to the terms of the underlying contract with the third party. Both of these guarantees are primarily issued to support public and private borrowing arrangements and, generally, have terms of one year or less. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers. The Company holds collateral, which may include accounts receivable, inventory, property, equipment, and income-producing properties, supporting those commitments if deemed necessary. In the event the customer does not perform in accordance with the terms of the agreement with the third-party, the Company would be required to fund the commitment. The maximum potential amount of future payments the Company could be required to make is represented by the contractual amount. If the commitment is funded, the Company would be entitled to seek recovery from the customer.

Interest rate lock commitments to originate residential mortgage loans held for sale and forward commitments to sell residential mortgage loans held for sale are considered derivative instruments (“mortgage derivatives”) and the contractual amounts were $50 million and $1 million, respectively, at December 31, 2021. 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 totaled $113 million and $20 million, respectively, at December 31, 2020. The net fair value of these mortgage derivatives combined was a net gain of $0.1 million at December 31, 2021, compared to a net loss of $0.2 million at December 31, 2020.

The Company has federal funds lines available with other financial institutions where funds may be borrowed on a short-term basis at the market rate in effect at the time of the borrowing. Federal funds lines of $195 million were available at December 31, 2021, compared to $175 million at December 31, 2020.

In the normal course of business, the Company is involved in various legal proceedings. In the opinion of management, any liability resulting from such proceedings would not have a material adverse effect on the consolidated financial statements.

NOTE 15. RELATED PARTY TRANSACTIONS

The Company conducts transactions, in the normal course of business, with its directors and officers, including companies in which they have a beneficial interest. The Company is required to disclose material related party transactions, other than certain compensation arrangements, entered into in the normal course of business. It is the Company’s policy to comply with federal regulations that require that these transactions with directors and executive officers be made on substantially the same terms as those prevailing at the time made for comparable transactions to other persons. Related party loans totaled approximately $113 million and $89 million at December 31, 2021 and 2020, respectively.

Nicolet has an active common stock repurchase program that allows for the repurchase of common stock in the open market, through block transactions, or in private transactions. During 2021, Nicolet repurchased common stock in a private transaction from one executive, Ann K. Lawson, including 2,193 shares for $0.2 million (or an average cost per share of $76.14). In comparison, during 2020, Nicolet repurchased common stock in private transactions from two executives, including 5,851 shares for $0.4 million (or an average cost per share of $71.45) from Robert B. Atwell and 5,852 shares for $0.4 million (or an average cost per share of $71.45) from Michael E. Daniels. These private transactions were made in conjunction with large stock option exercises by the executives. See Note 11 for additional information on stock option activity and see Note 12 for additional information on the common stock repurchase program.

As described in Note 1, the Company had a 50% ownership in a joint venture with the Firm in connection with the Company’s headquarters facility. The Firm is considered a related party, as one of its principals is a Board member and shareholder of the Company. Effective December 31, 2020, the Bank purchased the 50% ownership interest from the Firm for $8 million, to improve efficiencies in process and organizational structure, and to reflect that the Bank had expanded to occupy the majority of the building. Thus, at December 31, 2020, the Bank was the sole owner and managing member of the JV, with the JV operating as a wholly owned subsidiary of the Bank solely to hold the headquarters facility. Prior to this purchase, the Bank incurred approximately $1.3 million and $1.2 million in annual rent expense to the JV during 2020 and 2019, respectively.

In October 2013, the Company entered into a lease for a branch location in a facility owned by a different member of the Company’s Board and incurred annual rent expense of $124,000, $122,000, and $112,000, on this facility during 2021, 2020, and 2019, respectively. During 2019, this same Board member participated in a competitive bid process for and was awarded the contract as general contractor for the 2019 reconstruction of a different existing branch location. Total payments for the 2019

NOTE 17. REGULATORY CAPITAL REQUIREMENTS

The Company (on a consolidated basis) and the Bank are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company’s and Bank’s financial statements.

Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and Bank must meet specific capital guidelines that involve quantitative measures of their assets, liabilities and certain off-balance sheet items as calculated under regulatory accounting practices. The capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk-weightings, and other factors. Prompt corrective action provisions are not applicable to bank holding companies.

The Company and Bank must also maintain a “capital conservation buffer” consisting of CET1 in an amount equal to 2.5% of risk-weighted assets in order to avoid certain restrictions. The capital conservation buffer effectively increases the minimum well-capitalized CET1 capital, Tier 1 capital, and total capital ratios for U.S. banking organizations to 7.0%, 8.5%, and 10.5%, respectively.

Quantitative measures established by regulation to ensure capital adequacy require the Company and Bank to maintain minimum amounts and ratios of Total, Tier 1 and common equity Tier 1 (“CET1”) capital (as defined in the regulations) to risk-weighted assets (as defined), and Tier 1 capital (as defined) to average assets (as defined). Management believes the Company and the Bank met all capital adequacy requirements to which they are subject as of December 31, 2021 and 2020.

As of December 31, 2021 and 2020, the most recent notifications from the regulatory agencies categorized the Bank as well-capitalized under the regulatory framework for prompt corrective action. To be categorized as well-capitalized, an institution must maintain minimum Total risk-based, Tier 1 risk-based, CET1 risk-based and Tier 1 leverage ratios as set forth in the following table. There are no conditions or events since these notifications that management believes have changed the Bank’s category.

(1)The Total risk-based capital ratio is defined as Tier 1 capital plus tier 2 capital divided by total risk-weighted assets. The Tier 1 risk-based capital ratio is defined as Tier 1 capital divided by total risk-weighted assets. CET1 risk-based capital ratio is defined as Tier 1 capital, with deductions for goodwill and other intangible assets (other than mortgage servicing assets), net of associated deferred tax liabilities, and limitations on the inclusion of deferred tax assets, mortgage servicing assets and investments in other financial institutions, in each case as provided further in the rules, divided by total risk-weighted assets. The Leverage ratio is defined as Tier 1 capital divided by the most recent quarter’s average total assets as adjusted.

(2)Prompt corrective action provisions are not applicable at the bank holding company level.

Dividends declared by the Bank that exceed the retained net income for the most current year plus retained net income for the preceding two years must be approved by Federal regulatory agencies. At December 31, 2021, the Bank could pay dividends of approximately $7 million to the Company without seeking regulatory approval.

NOTE 18. 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 certain 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. Observable inputs are inputs that market participants would use in pricing the asset or liability based on market data obtained from independent sources. Unobservable inputs are inputs that reflect assumptions of the reporting entity about how market participants would price the asset or liability based on the best information available under the circumstances. The three fair value 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

NICOLET BANKSHARES, INC.

Notes to Consolidated Financial Statements

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.

The following is a description of the valuation methodologies used by the Company for the assets and liabilities 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 corporate debt securities, which are primarily trust preferred security investments, as well as certain municipal bonds and mortgage-backed securities. At December 31, 2021 and 2020, it was determined that carrying value was the best approximation of fair value for these Level 3 securities, based primarily on the internal analysis performed on these securities. The fair value of the derivative assets and liabilities is determined using a discounted cash flow analysis of the expected cash flows of each derivative, which considers the contractual terms of the underlying derivative financial instrument and observable market-based inputs, such as interest rate curves.

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

OREO	3,608		—		—		3,608
MSR asset	9,230		—		—		9,230

The following is a description of the valuation methodologies used by the Company for the items noted in the table above. For individually evaluated collateral dependent loans, the fair value 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, 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 fair value of the LSR asset is determined by stratifying the rights into tranches based on predominant characteristics, such as interest rate, loan type, and investor type, and a valuation model is used to calculate the present value of the expected future cash flows for each tranche. The servicing valuation models incorporate 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, accrued interest receivable, nonmaturing deposits, short-term borrowings, and accrued interest payable approximate their estimated fair value due to their immediate and shorter term maturities. 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 the 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 based on market participants. Collateral-dependent 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 valuation represents a Level 3 measurement.

Notes to Consolidated Financial Statements

Lending-related commitments: At December 31, 2021 and 2020, 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 21. REVENUE RECOGNITION

See Note 1 for the Company’s accounting policy on revenue recognition in accordance with Topic 606. This guidance does not apply to revenue associated with financial instruments, including revenue from loans and securities. In addition, certain noninterest income categories such as gains or losses associated with mortgage servicing rights, derivatives, and income from BOLI are not within the scope of the new guidance. The main types of revenue contracts within the scope of Topic 606 include trust services fee income, brokerage fee income, service charges on deposit accounts, card interchange income, and certain other noninterest income. These contracts are discussed in detail below.

Trust services and brokerage fee income: A contract between the Company and its customers to provide fiduciary and / or investment administration services on trust accounts and brokerage accounts in exchange for a fee. Trust services and brokerage fee income is generally based upon the month-end market value of the assets under management and the applicable fee rate, which is recognized over the period the underlying trust or brokerage account is serviced (generally on a monthly basis). Such contracts are generally cancellable at any time, with the customer subject to a pro-rated fee in the month of termination.

Service charges on deposit accounts: The deposit contract obligates the Company to serve as a custodian of the customer’s deposited funds and generally can be terminated at will by either party. This contract permits the customer to access the funds on deposit and request additional services related to the deposit account. Service charges on deposit accounts consist of account analysis fees (net fees earned on analyzed business and public checking accounts), monthly service charges, nonsufficient fund (“NSF”) charges, and other deposit account related charges. The Company’s performance obligation for account analysis fees and monthly service charges is generally satisfied, and the related revenue recognized, over the period in which the service is provided (typically on a monthly basis); while NSF charges and other deposit account related charges are largely transactional based and the related revenue is recognized at the time the service is provided.

Card interchange income: A contract between the Company, as a card-issuing bank, and its customers whereby the Company receives a transaction fee from the merchant’s bank whenever a customer uses a debit or credit card to make a purchase. The performance obligation is completed and the fees are recognized as the service is provided (i.e., when the customer uses a debit or credit card).

Other noninterest income: Other noninterest income includes several items, such as wire transfer income, check cashing fees, check printing fees, safe deposit box rental fees, management fee income, and consulting fees. These fees are generally recognized at the time the service is provided.

NOTE 22. OTHER ASSETS AND OTHER LIABILITIES HELD FOR SALE

On September 7, 2021, Nicolet entered into a Purchase and Assumption Agreement (the “Birmingham Agreement”) with Bank of Ann Arbor to sell Nicolet’s Birmingham, Michigan branch, including legacy mBank’s asset-based lending team (the “Birmingham Sale”). Pursuant to the terms of the Birmingham Agreement, Bank of Ann Arbor agreed to assume certain deposit liabilities and to acquire certain loans, as well as cash, personal property and other fixed assets associated with the Birmingham branch. The combined loan and deposit balances of the Birmingham branch (excluding certain loans and deposits not subject to the Birmingham Agreement) were approximately $199 million and $51 million, respectively, as of December 31, 2021. The Birmingham Sale closed on January 21, 2022.

Report of Independent Registered Public Accounting Firm

Audit Committee, Board of Directors, and Stockholders

Nicolet Bankshares, Inc.

Green Bay, Wisconsin

Opinions on the Financial Statements and Internal Control Over Financial Reporting

We have audited the accompanying consolidated balance sheet of Nicolet Bankshares, Inc. (the “Company”) as of December 31, 2021, the related consolidated statements of income, comprehensive income, changes in stockholders’ equity and cash flows the year ended December 31, 2021, and the related notes (collectively referred to as the “financial statements”). We also have audited the Company’s internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2021, and the results of its operations and its cash flows for the year ended December 31, 2021, in conformity with U.S. generally accepted accounting principles. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control – Integrated Framework: (2013) issued by COSO.

The Company acquired Mackinac Financial Corporation (Mackinac) and its subsidiary bank, mBank, by purchasing 100 percent of the outstanding shares of Mackinac’s common stock in September 2021. The Company also acquired County Bancorp, Inc. (County) and its subsidiary bank, Investors Community Bank, by purchasing 100 percent of the outstanding shares of County’s common stock in December 2021, and management excluded the Acquired Businesses from its assessment of the effectiveness of the Company’s internal control over financial reporting as of December 31, 2021. The Acquired Businesses represented approximately 40 percent and 10 percent of the Company’s total assets and total revenues, respectively, as of and for the year ended December 31, 2021. Our audit of internal control over financial reporting of the Company also excluded an evaluation of the internal control over financial reporting of the Acquired Businesses.

Basis for Opinions

The Company’s management is responsible for these financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s financial statements and an opinion on the Company’s internal control over financial reporting based on our audits.

We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audit of the financial statements included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures include examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audit also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

Definitions and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of reliable financial statements in accordance with U.S. generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the

maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with U.S. generally accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention, or timely detection and correction of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

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.

Critical Audit Matters

The critical audit matters communicated below are matters arising from the audit of the financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

Allowance for Credit Losses - Loans

Description of the Matter

The Company’s loan portfolio totaled $4.62 billion as of December 31, 2021, and the allowance for credit losses on loans (“ACL”) was $49.67 million.

As more fully described in Notes 1 and 4 to the financial statements, the ACL is an estimate of lifetime expected credit losses for loans. The estimate of the ACL considers historic loss rates that are adjusted for reasonable and supportable forecasts, as well as other qualitative adjustments. Loans that do not share risk characteristics and purchased credit deteriorated (“PCD”) loans are evaluated on an individual basis.

The Company measures expected credit losses of loans on a pool basis when the loans share similar characteristics. Historical loss rates are analyzed for the segmented loan pools and applied to their respective loan pools over the expected remaining life of the pooled loans. Historical loss rates are adjusted for significant factors that, in management’s judgment, reflect the impact of any current conditions on loss recognition, as well as for certain known model limitations. Forecast factors are developed based on information obtained from external sources, as well as consideration of other internal information, and are included in the ACL model for a reasonable and supportable forecast period. Management re-evaluates the other qualitative and environmental factors that it feels are likely to cause estimated credit losses to differ from the historical loss experience of each loan segment.

We identified the valuation of the ACL as a critical audit matter. Auditing the estimated ACL involved significant judgment and complex review. Auditing the ACL involved a high degree of subjectivity in evaluating management’s estimates, such as evaluating management’s segmentation, estimating the remaining life of loans in a pool, assessment of economic conditions and other environmental and forecast factors, evaluating the adequacy of specific allowances associated with individually evaluated loans and assessing the appropriateness of loan risk grades.

How We Addressed the Matter in Our Audit

Management’s process for establishing the ACL involves a high degree of subjectivity. We evaluated management’s process to assess economic conditions and other environmental factors, the adequacy of specific allowances associated with individually evaluated loans, and appropriateness of loan grades and other data used to calculate and estimate the various components of the ACL.

Our primary audit procedures related to the ACL and adoption of Topic 326 included the following, among others:

•Obtained an understanding of the Company’s process for establishing the ACL, including the implementation of models and the qualitative factor adjustments of the ACL.

•Tested the design and operating effectiveness of controls, including:

◦data completeness and accuracy,

◦classifications of loans by loan pool,

◦accuracy of historical net loss data and calculated net loss rates over the estimated life of each loan pool,

◦the establishment of qualitative and economic forecast adjustments, loan grades, and risk classification of loans, and

◦establishment of specific allowances associated with individually evaluated loans;

•Tested completeness and accuracy of the data utilized in the ACL;

•Tested the model’s computational accuracy;

•Evaluated the relevance and reliability of data and assumptions used in the estimate;

•Evaluated the qualitative and economic forecast adjustments to the historical loss rates, including assessing the basis for the adjustments and the reasonableness of the significant assumptions;

•Tested the internal loan review function and evaluated the reasonableness of loan grades and specific impairments, if any;

•Assessed the reasonableness of specific allowances associated with individually evaluated loans;

•Evaluated the accuracy and completeness of Topic 326 disclosures in the consolidated financial statements.

Business Combinations

Description of the Matter

As described in Note 2 to the consolidated financial statements, the Company completed acquisitions with two bank holding companies during the year ended December 31, 2021, resulting in the expansion of the Company’s operating footprint and additional goodwill of approximately $70 million being recognized on the Company’s consolidated balance sheet. Management determined that the acquisitions qualified as business combinations. Accordingly, all identifiable assets acquired and liabilities assumed were valued at fair value as part of the purchase price allocation as of each acquisition date. The identification and valuation of such acquired assets and assumed liabilities requires management to exercise significant judgment and consider the use of outside vendors to estimate the fair value allocations.

We identified the acquisitions and the related valuation of acquired assets and assumed liabilities as a critical audit matter. Auditing the acquired net assets and acquisition-related considerations involved a high degree of subjectivity in evaluating management’s operational assumptions of the acquisitions, fair value estimates, purchase price allocations and assessing the appropriateness of outside vendor valuation models.

How We Addressed the Matter in Our Audit

The primary procedures we performed to address the accounting for the business combinations included:

•Obtained and reviewed executed Agreement and Plan of Merger documents to gain an understanding of the underlying terms of the completed acquisitions

•Obtained and reviewed management’s business combination memos to gain an understanding of the procedures performed to identify and calculate the fair value of the acquired assets and liabilities

•Tested management’s business combination accounting analysis, focusing on the completeness and accuracy of the assets acquired and liabilities assumed and the related fair value purchase price allocations

•Obtained valuation estimates prepared by the Company’s external valuation specialists or prepared internally and challenged management’s analysis of the appropriateness of the valuations allocated to assets acquired and liabilities assumed; including but not limited to, testing of critical inputs, assumptions applied and valuation models utilized

•Utilized BKD’s internal valuation specialists to assist with evaluating the related fair value purchase price allocations made to certain identified assets acquired and liabilities assumed

•Tested the goodwill calculation resulting from the completed acquisitions, which is the difference between the total net consideration paid and the fair value of the net assets acquired

•Evaluated the accuracy and completeness of the disclosures made in the consolidated financial statements

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Stockholders and the Board of Directors of Nicolet Bankshares, Inc.

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheet of Nicolet Bankshares, Inc. and subsidiaries (the “Company”) as of December 31, 2020, and the related consolidated statements of income, comprehensive income, changes in stockholders’ equity and cash flows for each of the two years in the period then ended and the related notes (collectively, the consolidated financial statements).

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2020, and the results of their operations and their cash flows for each of the two years in the period then ended, in conformity with accounting principles generally accepted in the United States of America.

Change in Accounting Principle

As discussed in Note 1 to the consolidated financial statements, the Company has changed its method of accounting for the recognition and measurement of allowance for credit losses as of January 1, 2020 due to the adoption of ASC Topic 326, Financial Instruments – Credit Losses.

Basis for Opinion

The Company’s management is responsible for these consolidated financial statements. Our responsibility is to express an opinion on the Company’s consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with U.S. federal securities laws and applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud.

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing separate opinions on the critical audit matter or on the accounts or disclosures to which it relates.

Estimate of the allowance for credit losses – loans related to loans collectively evaluated for impairment

As described in Notes 1 and 4 to the consolidated financial statements, the Company’s allowance for credit losses – loans (ACL-Loans) totaled $32.2 million of which $30.9 million relates to loans collectively evaluated for impairment (general reserve). The Company estimated the general reserve using the weighted average remaining life method which utilizes historical loss rates of pools of loans with similar risk characteristics and then applied to the respective loan pool balances. These amounts are then adjusted for certain qualitative factors related to current conditions in addition to adjustments for reasonable and supportable forecasts for future periods.

We identified the estimate of the general reserve portion of the ACL-Loans as a critical audit matter because auditing it required significant auditor judgment and involved significant estimation uncertainty requiring industry knowledge and experience.

The primary audit procedures we performed to address this critical audit matter included:

•We evaluated the design and tested the operating effectiveness of key controls relating to the Company’s ACL-Loans calculation, including controls over the segmentation of the loan portfolio, the periods used in the calculation, the determination of qualitative factors including reasonable and supportable forecasts, and the precision of management’s review and approval of the calculation and resulting estimate

•We tested the completeness and accuracy of the data used by management to calculate historical loss rates adjusted for the remaining life of the loan pools

•We tested the completeness and accuracy of the data used by management in determining qualitative factor adjustments, including the reasonable and supportable factors, by agreeing them to internal and external information

•We analyzed the qualitative factors in comparison to historical periods to evaluate the directional consistency in relation to the Company’s loan portfolio and local economy

ITEM 9A. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Under the supervision, and with the participation of our management, including our principal executive officer and principal financial officer, we conducted an evaluation of our disclosure controls and procedures (as such term is defined in Exchange Act Rule 13a-15(e)) as of December 31, 2021. Based upon that evaluation, our principal executive officer and principal financial officer concluded that our disclosure controls and procedures were effective as of the end of the period covered by this report.

Changes in Internal Control Over Financial Reporting

During the fourth quarter of 2021 there were no changes in the Company’s internal control over financial reporting (as such term is defined in Exchange Act Rule 13a-15(f)) that materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

Management’s Annual Report on Internal Control Over Financial Reporting

Management of Nicolet Bankshares, Inc. is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting is defined in Rule 13a-15(f) promulgated under the Securities Exchange Act of 1934 as a process designed by, or under the supervision of, the Company’s principal executive and principal financial officers and effected by the Company’s board of directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of the Company’s financial statements for external purposes in accordance with generally accepted accounting principles and includes those policies and procedures that:

•Pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of the Company;

•Provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with accounting principles generally accepted in the United States of America, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and

•Provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Company’s assets that could have a material effect on the financial statements.

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.

Management has assessed the effectiveness of the Company’s internal control over financial reportingas of December 31, 2021, based on criteria for effective internal control over financial reporting established in “Internal Control — Integrated Framework,” issued by the Committee of Sponsoring Organization of the Treadway Commission (COSO). Management also conducted an assessment of requirements pertaining to Section 112 of the Federal Deposit Insurance Corporation Improvement Act. This section relates to management’s evaluation of internal control over financial reporting, including controls over the preparation of financial statements in accordance with the instructions to the Consolidated Financial Statements for Bank Holding Companies (Form FR Y-9C) and in compliance with laws and regulations. Our evaluation included a review of the documentation of controls, evaluations of the design of the internal control system and tests of the effectiveness of internal controls. Based on this assessment, management has determined that the Company’s internal control over financial reporting as of December 31, 2021, was effective.

BKD, LLP, the independent registered public accounting firm that audited the consolidated financial statements of the Company included in this Annual Report on Form 10-K, has issued an attestation report on the effectiveness of the Company’s internal control over financial reporting as of December 31, 2021.

Notwithstanding the other provisions of this Section 1.6, in the event of a merger, consolidation, reorganization, share exchange or other transaction as to which the holders of the capital stock of the Company before the transaction continue after the transaction to hold, directly or indirectly through a holding company or otherwise, shares of capital stock of the Company (or other surviving company) representing more than fifty percent (50%) of the value or ordinary voting power to elect directors of the capital stock of the Company (or other surviving company), such transaction shall not constitute a Change of Control.

3.Term and Termination.

3.1    Term. This Agreement shall remain in effect for the Term. While this Agreement remains in effect, it shall automatically renew each day after the date of this Agreement so that the Term remains a three-year term from day-to-day hereafter unless the Employer or the Executive gives written notice to the other of its intent that the automatic renewals shall cease. In the event such notice of non-renewal is properly given, this Agreement and the Term shall expire on the third anniversary of the thirtieth (30th) day following the date such written notice is received.

3.2    Termination. During the Term, the employment of the Executive under this Agreement may be terminated only as follows:

3.2.1    By the Employer:

(a)    For Cause, upon written notice to the Executive pursuant to Section 1.5 hereof, where the notice has been approved by a resolution passed by twothirds (2/3) of the directors of the Bank or the Company, as applicable, then in office; or

(b)    Without Cause at any time, provided that the Employer shall give the Executive thirty (30) days' prior written notice of its intent to terminate, in which event the Employer shall be required to (1) continue to meet its obligations under Section 4.1 for a period equal to the lesser of (i) twelve (12) months following the termination or (ii) the remaining Term of the Agreement, and (2) reimburse the Executive for the cost of premium payments paid by the Executive to continue his then existing health insurance for himself and his covered dependents as provided by the Employer for the lesser of (i) twelve (12) months following the date of termination of employment, or (ii) the health continuation coverage period for which the Executive is eligible as a result of the termination of employment.

3.2.2.    By the Executive:

(a)    For Good Reason, provided that the Executive shall give the Employer the prior written notice described in Section 1.12, in which event the Employer shall be required to (1) continue to meet its obligations under Section 4.1 for a period equal to the lesser of (i) twelve (12) months following the termination or (ii) the remaining Term of the Agreement, and (2) reimburse the Executive for the cost of premium payments paid by Executive to continue his then existing health insurance for himself and his covered dependents as provided by the Employer for the lesser of (i) twelve (12) months following the date of termination of employment, or (ii) the health continuation coverage period for which the Executive is eligible as a result of the termination of employment; or

(b)    For any reason other than Good Reason, provided that the Executive shall give the Employer thirty (30) days' prior written notice of his intent to terminate.

3.2.3.    Upon the Disability of the Executive at any time; provided that the Employer shall provide the Executive with at least thirty (30) days’ prior written notice of its intent to terminate the Executive, in which event, the Employer shall be required to continue to meet its obligations under Section 4.1 for a period of six (6) months following the termination or until the Executive begins receiving payments under the Bank’s long-term disability policy, whichever occurs first.

3.2.4.    At any time upon mutual, written agreement of the parties.

3.2.5.    Notwithstanding anything in this Agreement to the contrary, the Term shall end automatically upon the Executive's death.

3.3    Change of Control.

(a)    If, within six (6) months after a Change of Control as defined in Section 1.6, the Executive experiences an involuntary termination without Cause or the Executive terminates his employment with the Employer for Good Reason, the Executive, or in the event of his subsequent death, his designated beneficiaries or his estate, as the case may be, shall receive, as liquidated damages, in lieu of all other claims, (1) a lump sum severance payment equal to one and one-half (1.5) times the sum of the Executive’s Base Salary and target Annual Bonus opportunity as was in effect immediately preceding the Change of Control, if any; plus (2) reimbursement for the cost of premium payments paid by the Executive to continue his then existing health insurance for himself and his covered dependents as provided by the Employer for the lesser of (i) twelve (12) months following the date of termination of employment, or (ii) the health continuation coverage period for which the Executive is eligible as a result of the termination of employment, which shall be paid in cash in accordance with the Bank’s regular payroll practices, but no less frequently than monthly.

(b)    In no event shall the payment(s) described in this Section 3.3 exceed the amount permitted by Section 280G of the Internal Revenue Code, as amended (the ‘Code’). Therefore, if the aggregate present value (determined as of the date of the Change of Control in accordance with the provisions of Section 280G of the Code) of both the severance payment and all other payments to the Executive in the nature of compensation which are contingent on a change in ownership or effective control of the Bank or the Company or in the ownership of a substantial portion of the assets of the Bank or the Company (the ‘Aggregate Severance’) would result in a ‘parachute payment,’ as defined under Section 280G of the Code, then the Aggregate Severance shall not be greater than an amount equal to 2.99 multiplied by the Executive’s ‘base amount’ for the ‘base period,’ as those terms are defined under Section 280G of the Code. In the event the Aggregate Severance is required to be reduced pursuant to this Section 3.3, the latest payments in time shall be reduced first and if multiple portions of the Aggregate Severance to be reduced are paid at the same time, any non-cash payments will be reduced before any cash payments, and any remaining cash payments will be reduced pro rata.

3.4    Severance.

(a)    Payment of severance amounts due upon the Executive’s termination of employment pursuant to Sections 3.2.1(b); Section 3.2.2(a); Section 3.2.3 or Section 3.3, as applicable, including any reimbursements to which the Executive is entitled pursuant to Section 4.3, shall commence or be made, as applicable, on the first payroll date that is more than sixty (60) days after the Executive experiences a Separation from Service on or after the date the Executive’s employment is terminated.

(b)    Notwithstanding any provision in the Agreement to the contrary, to the extent necessary to avoid the imposition of tax on Executive under Code Section 409A, any payments that are otherwise payable to the Executive within the first six (6) months following the effective date of the Executive’s Separation from Service, shall be suspended and paid as soon as practicable following the end of the six-month period following such effective date if, immediately prior to the Executive’s Separation from Service, the Executive is determined to be a “specified employee” (within the meaning of Code Section 409A(a)(2)(B)(i)) of the Employer (or any related “service recipient” within the meaning of Code Section 409A and the regulations thereunder). Any payments suspended by operation of the foregoing sentence shall be paid as a lump sum in the seventh month following such effective date. Payments (or portions thereof) that would be paid latest in time during the six-month period will be suspended first.

3.5    Effect of Termination of Employment.

(a)    Upon termination of the Executive's employment hereunder, the Employer shall have no further obligations to the Executive or the Executive's estate with respect to this Agreement, except for the payment of salary and bonus amounts, if any, accrued pursuant to Sections 4.1 and 4.2 hereof and unpaid as of the effective date of the termination of employment and payments set forth in Sections 3.2.1(b); Section 3.2.2(a); Section 3.2.3; Section 3.3; and Section 4.3, as applicable. Nothing contained herein shall limit or impinge upon any other rights or remedies of the Employer or the Executive under any other agreement or plan to which the Executive is a party or of which the Executive is a beneficiary.

(b)    Notwithstanding any other provision of this Agreement to the contrary, as a condition of the Employer’s payment of any amount in connection with the Executive’s termination of employment pursuant to Sections 3.2.1(b); Section 3.2.2(a); Section 3.2.3; Section 3.3; and Section 4.3, as applicable, the Executive must execute and not timely revoke during any revocation period provided therein, a release in the form provided by the Employer. The Employer shall provide the release to the Executive in sufficient time so that if the Executive timely executes and returns the release, the revocation period will expire no later than sixty (60) days following the effective date of the termination of employment.

4.Compensation. The Executive shall receive the following salary and benefits during the Term, except as otherwise provided below:

4.1    Base Salary. During the Term in effect at the time of this Agreement, the Executive shall be compensated at a base rate of $325,000.00 per year (the “Base Salary”). The Executive's Base Salary shall be reviewed by the Chairman at least annually, and based on its evaluation of the Executive's performance, may recommend to the Board of Directors of the Bank or the Company, as applicable, that the Executive's Base Salary be increased in such amount, if any, as may be determined by the Board of Directors of the Bank or the Company, as applicable. Base Salary shall be payable in accordance with the Employer's normal payroll practices.

4.2    Annual Incentive Compensation. Unless otherwise prohibited by banking regulation, rule or directive, the Executive shall have the opportunity to earn annual bonus compensation in such manner as may be determined by, and based on performance measures and target levels as may be established by, the Board of Directors upon the recommendation of the Compensation Committee of the Board of Directors (the “Committee”) consistent with Bank’s strategic planning process, pursuant to any incentive compensation program as may be adopted from time to time by the Board of Directors (an “Annual Bonus”). Any Annual Bonus earned shall be payable in cash or cash equivalents by March 15th of the calendar year following the calendar year in which the bonus is earned in accordance with the Bank’s normal practices for the payment of short-term incentives. To be entitled to any payment of bonus compensation from the Bank pursuant to Section 4.2, the Executive must be employed by the Employer on the last day of the applicable performance period and must continue to be employed until the date that such payment is made.

4.3    Business Expenses; Memberships. The Employer specifically agrees to reimburse the Executive for:

(a)    reasonable and necessary business (including travel) expenses incurred by him in the performance of his duties hereunder, as approved by the Chairman; and

(b)    reasonable dues and business related expenditures, including initiation fees, associated with memberships, as selected by the Executive, including country clubs and professional associations which are commensurate with his position.

provided, however, that the Executive shall, as a condition of reimbursement, submit verification of the nature and amount of such expenses in accordance with reimbursement policies from time to time adopted by the Employer and in sufficient detail to comply with rules and regulations promulgated by the Internal Revenue Service. In no event shall any reimbursement pursuant to this Agreement be paid after the last day of the taxable year following the taxable year in which the expense was incurred. The amount of reimbursable expenses incurred in one taxable year shall not affect the expenses eligible for reimbursement in any other taxable year. Such right to reimbursement is not subject to liquidation or exchange for another benefit.

4.4 Benefits. In addition to the benefits specifically described in this Agreement, the Executive shall be entitled to such benefits as may be available from time to time to executives of the Employer similarly situated to the Executive. All such benefits shall be awarded and administered in accordance with the Employer's standard policies and practices. Such benefits may include, by way of example only, vacation pay, profit-sharing plans, retirement or investment funds, dental, health, life and disability insurance benefits and such other benefits as the Employer deems appropriate.

4.5    Withholding. The Employer may deduct from each payment of compensation hereunder all amounts required to be deducted and withheld in accordance with applicable federal and state income, FICA and other withholding requirements.

All expenses eligible for reimbursement under this Agreement must be incurred by the Executive during the Term of this Agreement to be eligible for reimbursement. All in-kind benefits described in this Agreement must be provided by the Employer during the Term of this Agreement. The amount of reimbursable expenses incurred, and the amount of in-kind benefits provided, in one taxable year shall not affect the expenses eligible for reimbursement, or in-kind benefits provided, in any other taxable year. All reimbursements shall be paid as soon as administratively practicable, but in no event shall any reimbursement be paid after the last day of the calendar year following the calendar year in which the expense was incurred. Such right to reimbursement or in-kind benefits are not subject to liquidation or exchange for another benefit.

5.Bank Information.

5.1    Ownership of Bank Information. All Bank Information received or developed by the Executive while employed by the Employer will remain the sole and exclusive property of the Employer.

5.2    Obligations of the Executive. The Executive agrees:

(a)    to hold Bank Information in strictest confidence;

(b)    not to use, duplicate, reproduce, distribute, disclose or otherwise disseminate Bank Information or any physical embodiments of Bank Information; and

(c)    in any event, not to take any action causing or fail to take any action necessary in order to prevent any Bank Information from losing its character or ceasing to qualify as Confidential Information or a Trade Secret.

In the event that the Executive is required by law to disclose any Bank Information, the Executive will not make such disclosure unless (and then only to the extent that) the Executive has been advised by independent legal counsel that such disclosure is required by law and then only after prior written notice is given to the Employer when the Executive becomes aware that such disclosure has been requested and is required by law. This Section 5 shall survive for a period of twelve (12) months following termination of this Agreement for any reason with respect to Confidential Information, and shall survive termination of this Agreement for any reason for so long as is permitted by applicable law, with respect to Trade Secrets.

•by the Executive other than for Good Reason pursuant to Section 3.2.2(b), or

•such employee is a full-time employee or a temporary employee of the Employer,

•such employment is pursuant to written agreement, and

•such employment is for a determined period or is at will.

9.    Remedies. The Executive agrees that the covenants contained in Sections 5 through 8 of this Agreement are of the essence of this Agreement; that each of the covenants is reasonable and necessary to protect the business, interests and properties of the Employer, and that irreparable loss and damage will be suffered by the Employer should he breach any of the covenants. Therefore, the Executive agrees and consents that, in addition to all the remedies provided by law or in equity, the Employer shall be entitled to a temporary restraining order and temporary and permanent injunctions to prevent a breach or contemplated breach of any of the covenants.

10.    Severability.

11.    No Set-Off by Executive. The existence of any claim, demand, action or cause of action by the Executive against the Employer whether predicated upon this Agreement or otherwise, shall not constitute a defense to the enforcement by the Employer of any of its rights hereunder.

14.    Waiver. A waiver by one party to this Agreement of any breach of this Agreement by the other party to this Agreement shall not be effective unless in writing, and no waiver shall operate or be construed as a waiver of the same or another breach on a subsequent occasion.
