PART I
 
Item 1. Business

General
Glacier Bancorp, Inc., headquartered in Kalispell, Montana, is a Montana corporation incorporated in 2004 as a successor corporation to the Delaware corporation originally incorporated in 1990. The terms “Company,” "we," "us" and "our" mean Glacier Bancorp, Inc. and its subsidiaries, when appropriate. The Company is a publicly-traded company and its common stock trades on the NASDAQ Global Select Market under the symbol GBCI. We provide a full range of banking services to individuals and businesses from 193 locations in Montana, Idaho, Utah, Washington, Wyoming, Colorado, Arizona and Nevada through our wholly-owned bank subsidiary, Glacier Bank (“Bank”). We offer a wide range of banking products and services, including: 1) retail banking; 2) business banking; 3) real estate, commercial, agriculture and consumer loans; and 4) mortgage origination and loan servicing. We serve individuals, small to medium-sized businesses, community organizations and public entities. For information regarding our lending, investment and funding activities, see “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

The Company includes the parent holding company and the Bank. As of December 31, 2020, the Bank consists of sixteen bank divisions and a corporate division. The bank divisions operate under separate names, management teams and advisory directors and include the following:
Glacier Bank (Kalispell, Montana) with operations in Montana;
First Security Bank of Missoula (Missoula, Montana) with operations in Montana;
Valley Bank of Helena (Helena, Montana) with operations in Montana;
First Security Bank (Bozeman, Montana) with operations in Montana;
Western Security Bank (Billings, Montana) with operations in Montana;

The corporate division includes the Bank’s investment portfolio and wholesale borrowings, and other centralized functions. We consider the Bank to be our sole operating segment.

The Bank has subsidiary interests in variable interest entities (“VIE”) for which the Bank has both the power to direct the VIE’s significant activities and the obligation to absorb losses or right to receive benefits of the VIE that could potentially be significant to the VIE. These subsidiary interests are included in the Company’s consolidated financial statements. The Bank also has subsidiary interests in VIEs for which the Bank does not have a controlling financial interest and is not the primary beneficiary. These subsidiary interests are not included in the Company’s consolidated financial statements.

The parent holding company owns non-bank subsidiaries that have issued trust preferred securities which qualify as Tier 2 regulatory capital instruments. The trust subsidiaries are not included in our consolidated financial statements. Our investments in the trust subsidiaries are included in other assets on our statements of financial condition.

As of December 31, 2020, the Company and its subsidiaries were not engaged in any operations in foreign countries.

Market Area and Competition
We have 193 locations, which consists of 172 branches and 21 loan or administration offices, in 71 counties within 8 states including Montana, Idaho, Utah, Washington, Wyoming, Colorado, Arizona and Nevada. The market area’s economic base primarily focuses on tourism, construction, mining, energy, manufacturing, agriculture, service industry, and health care. The tourism industry is highly influenced by national parks, ski resorts, significant lakes and rural scenic areas.

Commercial banking is a highly competitive business and operates in a rapidly changing environment. There are a large number of depository institutions including savings and loans, commercial banks, and credit unions in the markets in which we have locations. Competition is also increasing for deposit and lending services from internet-based competitors. Non-depository financial service institutions, primarily in the securities, insurance and retail industries, have also become competitors for retail savings, investment funds and lending activities. In addition to offering competitive interest rates, the principal methods used by the Bank to attract deposits include the offering of a variety of services including on-line banking, mobile banking and convenient office locations and business hours. The primary factors in competing for loans are interest rates and rate adjustment provisions, loan maturities, loan fees, relationships with customers and the quality of service.
The following table summarizes our number of locations, the number of counties we serve and the percentage of Federal Deposit Insurance Corporation (“FDIC”) insured deposits we have in those counties for each of the eight states we operate in. Percent of deposits are based on the FDIC summary of deposits survey as of June 30, 2020.

Human Capital
As of December 31, 2020, we employed 3,032 persons, 2,837 of whom were employed full time. No employees were represented by a collective bargaining group. We believe our employees are united by our commitment to serve our customers and communities and that our customers are best served by a staff of competent, caring employees who are customer oriented. Our employees are one of our most valuable assets. We consider our employee relations to be excellent.

We strive to provide a safe and gratifying workplace for our employees. We promote and support a work environment free from any form of harassment, discrimination, bullying, or retaliation, and we are committed to principles of equal employment opportunity and to taking affirmative steps to hire and advance qualified minorities, women, individuals with disabilities, and protected veterans. We also encourage employee growth and development in a variety of ways, including through formal and informal training, relationships with colleagues and internal mentors, and by making a variety of resources available.

The Company has established a Training Committee charged with creating company-wide training expectations for employees to encourage adherence to internal policies and procedures and compliance with the variety of laws and regulations applicable to our operations. We also strive to offer multidisciplinary educational opportunities for employees to improve their knowledge and skills for their current positions, as well as to create opportunities to advance within the organization. Other targeted development opportunities are available for group leaders and promising employees, such as tuition support for employees seeking additional degrees or certifications through our Tuition Reimbursement program.

Our employee’s overall health and well-being is a top priority. It is our goal for all employees to work hard and experience a high quality work life, but we also encourage employees to be active participants in our communities, and to enjoy quality time with their families and cultivate their independent interests. We have developed several programs to encourage a safe and healthy workplace, including:

• GBCI Injury and Illness Prevention Program
• Work-life Balance Employee Assistance Program (EAP)
• WellSteps program offering assessments, goal setting tools, activities, incentives, and rewards
• The appointment of Safety & Wellness Ambassadors
• Quarterly Wellness Campaigns
• Workstation Ergonomics Assessments

Through our Injury and Illness Prevention Program, we have established protocols for minimizing work place injuries and incidents. Instilling safety as a standard of practice is facilitated by a Safety Committee at each of our banking divisions and by Safety & Wellness Ambassadors at each location.

We also believe employee retention is critical to our success, and we are proud of our track record when it comes to retaining employees, including many employees at institutions we acquire. Retention strategies are woven into all our compensation and retirement programs, and even our efforts at expansion. We provide our qualifying employees with a comprehensive benefit program, including health, dental and vision insurance, life and accident insurance, short- and long-term disability coverage, vacation and sick leave. In addition we offer a Profit Sharing and 401(k) Plan, stock-based compensation plan, deferred compensation plans, and a supplemental executive retirement plan for certain employees (“SERP”). For select management-level employees, we also offer our Short and Long-Term Incentive Plans, which are cash and equity-based compensation plans, respectively, that are designed to encourage achievement of short and long-term financial goals as our determined by our Board of Directors from time to time, and to further retention through long-term vesting of certain awards earned. See Note 14 in the Consolidated Financial Statements in “Item 8. Financial Statements and Supplementary Data” for detailed information regarding employee benefit plans and eligibility requirements.

We adapted quickly during the COVID-19 pandemic, to ensure that our employees were able to continue to work, receive a paycheck and to assist those who could not work. We quickly provided work from home capabilities for those employees who were able to do their jobs remotely. This action helped to create space for our employees and help slow the spread of the virus. We established a special time off benefit provided to those due to virus exposure or childcare issues so that they could remain at home, receive their pay and not exhaust their usual time off benefits. In addition we moved our vacation accrual caps to allow additional accruals for employees who continued to work during the pandemic. For employees who continued to work on site, we implemented safety protocols to mitigate risk of exposure. In addition, we expanded the scope of our EAP and regularly provided resources to employees to encourage wellness during the course of the pandemic.

Board of Directors and Committees
The Company's Board of Directors (“Board”) has the ultimate authority and responsibility for overseeing risk management at the Company. Some aspects of risk oversight are fulfilled at the Board level, and the Board delegates other aspects of its risk oversight function to its committees. The Board has established, among others, an Audit Committee, a Compensation Committee, a Nominating/Corporate Governance Committee, a Compliance Committee, and a Risk Oversight Committee. Additional information regarding Board committees is set forth under the heading “Meetings and Committees of the Board of Directors - Committee Membership” in the Company’s 2021 Annual Meeting Proxy Statement (“Proxy Statement”) and is incorporated herein by reference.

Copies can also be obtained by accessing the SEC’s website (www.sec.gov).

Supervision and Regulation
We are subject to extensive regulation under federal and state laws. This section provides a general overview of the federal and state regulatory framework applicable to us. In general, this regulatory framework is designed to protect depositors, the federal Deposit Insurance Fund (“DIF”), and the federal and state banking system as a whole, rather than specifically for the protection of shareholders. Note that this section is not intended to summarize all laws and regulations applicable to us. Descriptions of statutory or regulatory provisions do not purport to be complete and are qualified by reference to those provisions.

These statutes and regulations, as well as related policies, continue to be subject to change by Congress, state legislatures, and federal and state regulators. Changes in statutes, regulations, or regulatory policies applicable to us (including their interpretation or implementation) cannot be predicted and could have a material effect on our business and operations. Numerous changes to the statutes, regulations, and regulatory policies applicable to us have been made or proposed in recent years. Continued efforts to monitor and comply with new regulatory requirements add to the complexity and cost of our business and operations.

The Company is subject to regulation and supervision by the Federal Reserve and the Montana Department of Administration’s Division of Banking and Financial Institutions (“MT Division of Banking”) and regulation generally by the State of Montana. The Company is also subject to the disclosure and regulatory requirements of the Securities Act of 1933, as amended, and the Securities Exchange Act of 1934, as amended, which are both administered by the SEC. The Bank is subject to regulation and supervision by the FDIC, the MT Division of Banking, and, with respect to Bank branches outside of the State of Montana, the respective regulators in those states.

Federal and State Bank Holding Company Regulation
General. The Company is a bank holding company under the Bank Holding Company Act of 1956, as amended (“BHCA”), due to its ownership of and control over the Bank. As a bank holding company, the Company is subject to regulation, supervision, and examination by the Federal Reserve. Further, because the Bank is a “regional banking organization” under Montana law, the Company (as a bank holding company of the Bank) is also subject to regulation, supervision and examination by the MT Division of Banking. In general, the BHCA limits the business of a bank holding company to owning or controlling banks and engaging in, or retaining or acquiring shares in a company engaged in, other activities closely related to the business of banking. In addition, the Company must also file reports with and provide additional information to the Federal Reserve.

Holding Company Bank Ownership. The BHCA requires every bank holding company to obtain the prior approval of the Federal Reserve before: 1) acquiring, directly or indirectly, ownership or control of any voting shares of another bank or bank holding company if, after such acquisition, it would own or control more than 5 percent of such shares; 2) acquiring all or substantially all of the assets of another bank or bank holding company; or 3) merging or consolidating with another bank holding company.

Holding Company Control of Non-banks. With some exceptions, the BHCA prohibits a bank holding company from acquiring or retaining direct or indirect ownership or control of more than 5 percent of the voting shares of any company that is not a bank or bank holding company, or from engaging directly or indirectly in activities other than those of banking, managing or controlling banks, or providing services for its subsidiaries. The principal exceptions to these prohibitions involve certain non-bank activities that, by federal statute, agency regulation, or order, have been identified as activities closely related to the business of banking or managing or controlling banks.

Transactions with Affiliates. Bank subsidiaries of a bank holding company are subject to restrictions imposed by the Federal Reserve Act on extensions of credit to the holding company or its subsidiaries, on investments in securities, and on the use of securities as collateral for loans to any borrower. The Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (“Dodd-Frank Act”) further extended the definition of an “affiliate” and treats credit exposure arising from derivative transactions, securities lending, and borrowing transactions as covered transactions under the regulations. It also 1) expands the scope of covered transactions required to be collateralized; 2) requires collateral to be maintained at all times for covered transactions required to be collateralized; and 3) places limits on acceptable collateral. These regulations and restrictions may limit the Company’s ability to obtain funds from the Bank for its cash needs, including funds for payments of dividends, interest, and operational expenses.

Tying Arrangements. We are also prohibited from engaging in certain tie-in arrangements in connection with any extension of credit, sale or lease of property, or furnishing of services. For example, with certain exceptions, we may not condition an extension of credit
7


to a customer on either 1) a requirement that the customer obtain additional services provided by us; or 2) an agreement by the customer to refrain from obtaining other services from a competitor.

Support of Bank Subsidiaries. Under Federal Reserve policy and the Dodd-Frank Act, the Company is required to act as a source of financial and managerial strength to the Bank. This means that the Company is required to commit, as necessary, capital and resources to support the Bank, including at times when the Company may not be in a financial position to provide such resources or when it may not be in the Company's or its shareholders' best interests to do so. Any capital loans a bank holding company makes to its bank subsidiaries are subordinate to deposits and to certain other indebtedness of the bank subsidiaries.

State Law Restrictions under Corporate Law. As a Montana corporation, the Company is subject to certain limitations and restrictions under applicable Montana corporate law. For example, Montana corporate law includes limitations and restrictions relating to indemnification of directors, distributions to shareholders, transactions involving directors, officers, or interested shareholders, maintenance of books, records, and minutes, and observance of certain corporate formalities.

Federal and State Regulation of the Bank
General. Deposits in the Bank are insured by the FDIC. The Bank is subject to primary supervision, periodic examination, and regulation of the FDIC and the MT Division of Banking. These agencies have the authority to prohibit the Bank from engaging in what they believe constitute unsafe or unsound banking practices. The federal laws that apply to the Bank regulate, among other things, the scope of its business, its investments, its reserves against deposits, the timing of the availability of deposited funds, and the nature and amount of and collateral for loans. Federal laws also regulate community reinvestment and insider credit transactions and impose safety and soundness standards. In addition to federal law and the laws of the State of Montana, with respect to the Bank's branches in Idaho, Utah, Washington, Wyoming, Colorado, Arizona and Nevada, the Bank is also subject to the various laws and regulations governing its activities in those states.

Consumer Protection. The Bank is subject to a variety of federal and state consumer protection laws and regulations that govern its relationships and interactions with consumers, including laws and regulations that impose certain disclosure requirements and that govern the manner in which the Bank takes deposits, makes and collects loans, and provides other services. In recent years, examination and enforcement by federal and state banking agencies for non-compliance with consumer protection laws and regulations have increased and become more intense. Failure to comply with these laws and regulations may subject the Bank to various penalties, including but not limited to enforcement actions, injunctions, fines, civil monetary penalties, criminal penalties, punitive damages, and the loss of certain contractual rights. The Bank has established a comprehensive compliance system to ensure consumer protection.

Community Reinvestment. The Community Reinvestment Act of 1977 (“CRA”) requires that, in connection with examinations of financial institutions within their jurisdictions, federal bank regulators evaluate the record of financial institutions in meeting the credit needs of their local communities, including low and moderate-income neighborhoods, consistent with the safe and sound operation of those institutions. A bank’s community reinvestment record is also considered by the applicable banking agencies in evaluating mergers, acquisitions, and applications to open a branch or facility. In some cases, a bank's failure to comply with the CRA, or CRA protests filed by interested parties during applicable comment periods, can result in the denial or delay of such transactions. The Bank received a “satisfactory” rating in its most recent CRA examination.

Insider Credit Transactions. Banks are subject to certain restrictions on extensions of credit to executive officers, directors, principal shareholders, and their related interests. These extensions of credit 1) must be made on substantially the same terms (including interest rates and collateral) and follow credit underwriting procedures that are at least as stringent as those prevailing at the time for comparable transactions with persons not related to the lending bank; and 2) must not involve more than the normal risk of repayment or present other unfavorable features. Banks are also subject to certain lending limits and restrictions on overdrafts to insiders. A violation of these restrictions may result in the assessment of substantial civil monetary penalties, regulatory enforcement actions, and other regulatory sanctions. The Dodd-Frank Act and federal regulations place additional restrictions on loans to insiders and generally prohibit loans to senior officers other than for certain specified purposes.

Regulation of Management. Federal law 1) sets forth circumstances under which officers or directors of a bank may be removed by the bank's federal supervisory agency; 2) as discussed above, places restraints on lending by a bank to its executive officers, directors, principal shareholders, and their related interests; and 3) generally prohibits management personnel of a bank from serving as directors or in other management positions of another financial institution whose assets exceed a specified amount or which has an office within a specified geographic area.

Safety and Soundness Standards. Certain non-capital safety and soundness standards are also imposed upon banks. These standards cover, among other things, internal controls, information systems and internal audit systems, loan documentation, credit underwriting, interest rate exposure, asset growth, compensation, fees and benefits, such other operational and managerial standards as the agency determines to be appropriate, and standards for asset quality, earnings, and stock valuation. In addition, each insured depository
8


institution must implement a comprehensive written information security program that includes administrative, technical, and physical safeguards appropriate to the institution’s size and complexity and the nature and scope of its activities. The information security program must be designed to ensure the security and confidentiality of customer information, protect against unauthorized access to or use of such information, and ensure the proper disposal of customer and consumer information. An institution that fails to meet these standards may be required to submit a compliance plan, or be subject to regulatory sanctions, including restrictions on growth. The Bank has established comprehensive policies and risk management procedures to ensure the safety and soundness of the Bank.

Interstate Banking and Branching
The Dodd-Frank Act eliminated interstate branching restrictions that were implemented as part of the Riegle-Neal Interstate Banking and Branching Efficiency Act of 1994 ("Interstate Act"), and removed many restrictions on de novo interstate branching by state and federally chartered banks.  Federal regulators have authority to approve applications by such banks to establish de novo branches in states other than the bank's home state if the host state's banks could establish a branch at the same location. The Interstate Act requires regulators to consult with community organizations before permitting an interstate institution to close a branch in a low-income area. Federal bank regulations prohibit banks from using their interstate branches primarily for deposit production and federal bank regulatory agencies have implemented a loan-to-deposit ratio screen to ensure compliance with this prohibition.

Dividends
A principal source of the Company’s cash is from dividends received from the Bank, which are subject to regulation and limitation. As a general rule, regulatory authorities may prohibit banks and bank holding companies from paying dividends in a manner that would constitute an unsafe or unsound banking practice. For example, regulators have stated that paying dividends that deplete an institution's capital base to an inadequate level would be an unsafe and unsound banking practice and that an institution should generally pay dividends only out of current operating earnings. In addition, a bank may not pay cash dividends if that payment could reduce the amount of its capital below that necessary to meet minimum applicable regulatory capital requirements. Current guidance from the Federal Reserve provides, among other things, that dividends per share on the Company’s common stock generally should not exceed earnings per share, measured over the previous four fiscal quarters. In certain circumstances, Montana law also places limits or restrictions on a bank’s ability to declare and pay dividends.

Rules adopted in accordance with the third installment of the Basel Accords (“Basel III”) also impose limitations on the Bank's ability to pay dividends. In general, these rules limit the Bank's ability to pay dividends unless the Bank's common equity conservation buffer exceeds the minimum required capital ratio by at least 2.5 percent of risk-weighted assets.

The Federal Reserve has also issued a policy statement on the payment of cash dividends by bank holding companies. In general, the policy statement expresses the view that although no specific regulations restrict dividend payments by bank holding companies other than state corporate laws, a bank holding company should not pay cash dividends unless the bank holding company’s earnings for the past year are sufficient to cover both the cash dividends and a prospective rate of earnings retention that is consistent with the bank holding company’s capital needs, asset quality, and overall financial condition. A bank holding company's ability to pay dividends may also be restricted if a subsidiary bank becomes undercapitalized. These various regulatory policies may affect our ability to pay dividends or otherwise engage in capital distributions.

The Dodd-Frank Act
General. The Dodd-Frank Act significantly changed the bank regulatory structure and has affected the lending, deposit, investment, trading, and operating activities of banks and bank holding companies. Some of the provisions of the Dodd-Frank Act that may impact our business and operations are summarized below.

Corporate Governance. The Dodd-Frank Act requires publicly traded companies to provide their shareholders with 1) a non-binding shareholder vote on executive compensation; 2) a non-binding shareholder vote on the frequency of such vote; 3) disclosure of “golden parachute” arrangements in connection with specified change in control transactions; and 4) a non-binding shareholder vote on golden parachute arrangements in connection with these change in control transactions. The SEC adopted a rule mandated by the Dodd-Frank Act that requires a public company to disclose the ratio of the compensation of its Chief Executive Officer (“CEO”) to the median compensation of its employees. This rule is intended to provide shareholders with information that they can use to evaluate a CEO’s compensation.

Prohibition Against Charter Conversions of Financial Institutions. The Dodd-Frank Act generally prohibits a depository institution from converting from a state to federal charter, or vice versa, while it is the subject to an enforcement action unless the depository institution seeks prior approval from its primary regulator and complies with specified procedures to ensure compliance with the enforcement action.

Repeal of Demand Deposit Interest Prohibition. The Dodd-Frank Act repealed the federal prohibitions on the payment of interest on demand deposits, thereby permitting depository institutions to pay interest on business transaction and other accounts.

Consumer Financial Protection Bureau. The Dodd-Frank Act established the Consumer Financial Protection Bureau (“CFPB”) and empowered it to exercise broad rulemaking, supervision, and enforcement authority for a wide range of consumer protection laws. Because our total consolidated assets exceed $10 billion, we are subject to the direct supervision of the CFPB. The CFPB has issued and continues to issue numerous regulations under which we will continue to incur additional expense in connection with our ongoing compliance obligations. Significant recent CFPB developments that may affect operations and compliance costs include:
positions taken by the CFPB on fair lending, including applying the disparate impact theory which could make it more difficult for lenders to charge different rates or to apply different terms to loans to different customers;
the CFPB's final rule amending Regulation C, which implements the Home Mortgage Disclosure Act, requiring most lenders to report expanded information in order for the CFPB to more effectively monitor fair lending concerns and other information shortcomings identified by the CFPB;
positions taken by the CFPB regarding the Electronic Fund Transfer Act and Regulation E, which require companies to obtain consumer authorizations before automatically debiting a consumer’s account for pre-authorized electronic funds transfers; and
focused efforts on enforcing certain compliance obligations the CFPB deems a priority, such as automobile and student loan servicing, debt collection, mortgage origination and servicing, remittances, and fair lending, among others.

Interchange Fees. Under the Durbin Amendment to the Dodd-Frank Act, the Federal Reserve adopted rules establishing standards for assessing whether the interchange fees that may be charged with respect to certain electronic transactions are "reasonable and proportional" to the costs incurred by issuers for processing such transactions. Notably, the Federal Reserve's rules set a maximum permissible interchange fee, among other requirements. Because our total consolidated assets exceeded $10 billion during the first quarter of 2018, we became subject to the interchange fee cap beginning July 1, 2019 on a go-forward basis.

Stress Testing
In May 2018, the Economic Growth, Regulatory Relief, and Consumer Protection Act (“EGRRC Act”) was signed into law, which is bipartisan legislation that rolled back certain provisions of the Dodd-Frank Act to provide regulatory relief to certain financial institutions. In relevant part, the EGRRC Act raised the applicability threshold for company-run stress testing required under the Dodd-Frank Act by exempting bank holding companies under $100 billion in total assets and raising the asset threshold for covered banks from $10 billion to $250 billion. In November of 2019, the FDIC adopted a final rule to implement these changes. As a result, we are not currently subject to the Dodd-Frank Act stress testing requirements.

Capital Adequacy
Banks and bank holding companies are subject to various regulatory capital requirements administered by state and federal regulatory agencies, which involve quantitative measures of assets, liabilities, and certain off-balance sheet items calculated under regulatory guidelines. Capital amounts and classifications are also subject to qualitative judgments by regulators about components, risk weighting, and other factors. The capital requirements are intended to ensure that institutions have adequate capital given the risk levels of assets and off-balance sheet financial instruments and are applied separately to the Company and the Bank.

Federal regulations require insured depository institutions and bank holding companies to meet several minimum capital standards, including: 1) a common equity Tier 1 capital to risk-based assets ratio of 4.5 percent; 2) a Tier 1 capital to risk-based assets ratio of 6 percent; 3) a total capital to risk-based assets ratio of 8 percent; and 4) a 4 percent Tier 1 capital to total assets leverage ratio. These minimum capital requirements became effective in January 2015 and were the result of final rules implementing certain regulatory amendments based on the recommendation of the Basel Committee on Banking Supervision and certain requirements of the Dodd-Frank Act ("Final Rules").
The Final Rules also require a capital conservation buffer designed to absorb losses during periods of economic stress. Failure to comply with this buffer requirement may result in constraints on capital distributions (e.g., dividends, equity repurchases, and certain bonus compensation for executive officers). The Final Rules change the risk-weights of certain assets for purposes of the risk-based capital ratios and phase out certain instruments as qualifying capital. For additional information regarding trust preferred securities and their impact to regulatory capital, see Note 10 to the Consolidated Financial Statements in “Item 8. Financial Statements and Supplementary Data.”

The Final Rules also contain revisions to the prompt corrective action framework, which is designed to place restrictions on an insured depository institution if its capital levels begin to show signs of weakness. Under the prompt corrective action requirements, which are designed to complement the capital conservation buffer, insured depository institutions will be required to meet the following increased capital level requirements to qualify as “well capitalized”: 1) a Tier 1 common equity capital ratio of at least 6.5 percent; 2) a Tier 1 capital ratio of at least 8 percent; 3) a total capital ratio of at least 10 percent; 4) a Tier 1 leverage ratio of at least 5 percent; and 5) not be subject to any order or written directive requiring a specific capital level. The FDIC’s rules (as amended by the Final Rules) contain other capital classification categories, such as “adequately capitalized,” “undercapitalized,” “significantly undercapitalized,” and “critically undercapitalized,” each of which are based on certain capital ratios. Undercapitalized institutions are subject to certain mandatory restrictions, including on capital distributions and growth. Significantly undercapitalized and critically
10


undercapitalized institutions are subject to additional restrictions. An institution may be downgraded to a category lower than indicated by its capital ratios if it is determined to be in an unsafe or unsound condition, or if the institution receives an unsatisfactory examination rating.

The application of the Final Rules may result in lower returns on invested capital, require the raising of additional capital or require regulatory action if the Bank were unable to comply with such requirements. In addition, management may be required to modify its business strategy due to the changes to the asset risk-weights for risk-based capital calculations and the requirement to meet the capital conservation buffers. The imposition of liquidity requirements in connection with these rules could also cause the Bank to increase its holdings of liquid assets, change its business strategy, and make other changes to the terms of its funding.

Regulatory Oversight and Examination
Inspections. The Federal Reserve conducts periodic inspections of bank holding companies. In general, the objectives of the Federal Reserve's inspection program are to ascertain whether the financial strength of a bank holding company is maintained on an ongoing basis and to determine the effects or consequences of transactions between a bank holding company or its non-banking subsidiaries and its bank subsidiaries. The inspection type and frequency typically varies depending on asset size, complexity of the organization, and the bank holding company’s rating at its last inspection.

Examinations. Banks are subject to periodic examinations by their primary regulators. In assessing a bank's condition, bank examinations have evolved from reliance on transaction testing to a risk-focused approach. These examinations are extensive and cover the entire breadth of the operations of a bank. Generally, safety and soundness examinations occur on an 18-month cycle for banks under $3 billion in total assets that are well capitalized and without regulatory issues, and 12-months otherwise. Examinations alternate between the federal and state bank regulatory agencies, and in some cases they may occur on a combined schedule. The frequency of consumer compliance and CRA examinations is linked to the size of the institution and its compliance and CRA ratings at its most recent examinations. However, the examination authority of the Federal Reserve and the FDIC allows them to examine supervised institutions as frequently as deemed necessary based on the condition of the institution or as a result of certain triggering events. Because our total consolidated assets exceed $10 billion, we are also subject to the direct supervision of the CFPB.

Commercial Real Estate Ratios. The federal banking regulators recently issued guidance reminding financial institutions to reexamine the existing regulations regarding concentrations in commercial real estate lending. The purpose of the guidance is to guide banks in developing risk management practices and capital levels commensurate with the level and nature of real estate concentrations. The banking regulators are directed to examine each bank’s exposure to commercial real estate loans that are dependent on cash flow from the real estate held as collateral and to focus their supervisory resources on institutions that may have significant commercial real estate loan concentration risk. The guidance provides that the strength of an institution’s lending and risk management practices with respect to such concentrations will be taken into account in evaluating capital adequacy and does not specifically limit a bank’s commercial real estate lending to a specified concentration level.

Corporate Governance and Accounting
The Sarbanes-Oxley Act of 2002 (“SOX Act”) addressed, among other things, corporate governance, auditing and accounting, enhanced and timely disclosure of corporate information, and penalties for non-compliance. In general, the SOX Act among other matters 1) requires chief executive officers and chief financial officers to certify to the accuracy and completeness of periodic reports filed with the SEC and to certain matters relating to disclosure and accounting controls at public companies; 2) imposes specific and enhanced corporate disclosure requirements; 3) accelerates the time frame for reporting insider transactions and periodic disclosures by public companies; and 4) requires companies to adopt and disclose information about corporate governance practices. As a publicly reporting company with the SEC, the Company is subject to the requirements of the SOX Act and related rules and regulations issued by the SEC and NASDAQ.

Anti-Money Laundering and Anti-Terrorism
The Bank Secrecy Act (“BSA”) requires all financial institutions to establish a risk-based system of internal controls reasonably designed to prevent money laundering and the financing of terrorism. The BSA also sets forth various recordkeeping and reporting requirements (such as reporting suspicious activities that might signal criminal activity) and certain due diligence and "know your customer" documentation requirements.

The Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001 (“Patriot Act”), intended to combat terrorism, was renewed with certain amendments in 2006. In relevant part, the Patriot Act 1) prohibits banks from providing correspondent accounts directly to foreign shell banks; 2) imposes due diligence requirements on banks opening or holding accounts for foreign financial institutions or wealthy foreign individuals; 3) requires financial institutions to establish an anti-money laundering compliance program; and 4) eliminates civil liability for persons who file suspicious activity reports. The Patriot Act also includes provisions providing the government with power to investigate terrorism, including expanded government access to bank account records. Regulators are directed to consider a bank holding company’s and a bank’s effectiveness
11


in combating money laundering when reviewing and ruling on applications under the BHCA and the Bank Merger Act. We have established comprehensive compliance programs designed to comply with the requirements of the BSA and Patriot Act.

Financial Services Modernization
The Gramm-Leach-Bliley Financial Services Modernization Act of 1999 (“GLBA”) brought about significant changes to the laws affecting banks and bank holding companies. Generally, the GLBA 1) repeals historical restrictions on preventing banks from affiliating with securities firms; 2) provides a uniform framework for the activities of banks, savings institutions, and their holding companies; 3) broadens the activities that may be conducted by national banks and banking subsidiaries of bank holding companies; 4) provides an enhanced framework for protecting the privacy of consumer information and requires notification to consumers of bank privacy policies; and 5) addresses a variety of other legal and regulatory issues affecting both day-to-day operations and long-term activities of financial institutions. The Bank is subject to FDIC regulations implementing the privacy provisions of the GLBA. These regulations require a bank to disclose its privacy policy, including informing consumers of the bank's information sharing practices and their right to opt out of certain practices.

Deposit Insurance
FDIC Insured Deposits. The Bank's deposits are insured under the Federal Deposit Insurance Act, up to the maximum applicable limits and are subject to deposit insurance assessments by the FDIC, which are designed to tie what banks pay for deposit insurance to the risks they pose. The Dodd-Frank Act redefined the assessment base used for calculating deposit insurance assessments by requiring the FDIC to determine assessments based on the average consolidated total assets less average tangible equity capital of a financial institution. Under the FDIC’s assessment system for determining payments to the DIF, insured depository institutions with more than $10 billion in assets are assessed under a “scorecard” methodology that seeks to capture both the probability that such an institution will fail and the magnitude of the impact on the DIF if such a failure occurs. In addition, the Dodd-Frank Act 1) raised the minimum designated reserve ratio (the FDIC is required to set the reserve ratio each year) of the DIF from 1.15 percent to 1.35 percent; 2) required that the DIF reserve ratio meet 1.35 percent by 2020; and 3) eliminated the requirement that the FDIC pay dividends to insured depository institutions when the reserve ratio exceeds certain thresholds. The Dodd-Frank Act made banks with $10 billion or more in total assets responsible for the increase from 1.15 percent to 1.35 percent by imposing a surcharge on those institutions. The surcharge continued through September of 2018 when the DIF reserve ratio reached 1.36 percent, which was ahead of the Dodd-Frank Act’s 2020 deadline to meet the 1.35 percent reserve ratio. No institution may pay a dividend if it is in default on its federal deposit insurance assessment. The FDIC may also prohibit any insured institution from engaging in any activity determined by regulation or order to pose a serious risk to the DIF.

Safety and Soundness. The FDIC may terminate the deposit insurance of any insured depository institution if the FDIC determines after a hearing that the institution has engaged or is engaging in unsafe or unsound practices, is in an unsafe or unsound condition to continue operations, or has violated any applicable law, regulation, order, or any condition imposed by an agreement with the FDIC. Management is not aware of any existing circumstances that would result in termination of the Bank's deposit insurance.

Insurance of Deposit Accounts. The Dodd-Frank Act permanently increased FDIC deposit insurance from $100,000 to $250,000 per depositor. The FDIC insurance coverage limit applies per depositor, per insured depository institution for each account ownership category.

Recent and Proposed Legislation
The economic and political environment of the past several years has led to a number of proposed legislative, governmental, and regulatory initiatives that may significantly impact the banking industry. Other regulatory initiatives by federal and state government agencies may also significantly impact our business. We cannot predict whether these or any other proposals will be enacted or the ultimate impact of any such initiatives on our operations, competitive situation, financial conditions, or results of operations. Recent history has demonstrated that new legislation or changes to existing laws or regulations typically result in a greater compliance burden (and therefore increase the general costs of doing business), and the new administration under President Biden has demonstrated a general intent to regulate the financial services industry more strictly than the administration of his predecessor.

Effects of Federal Government Monetary Policy
The Company’s earnings and growth are affected not only by general economic conditions, but also by the fiscal and monetary policies of the federal government, particularly the Federal Reserve. The Federal Reserve implements national monetary policy to promote maximum employment, stable prices, and moderate long-term interest rates. Through its open market operations in U.S. government securities, control of the discount rate applicable to borrowings, establishment of reserve requirements against certain deposits, and control of the interest rate applicable to excess reserve balances and reverse repurchase agreements, the Federal Reserve influences the availability and cost of money and credit and, ultimately, a range of economic variables including employment, output, and the prices of goods and services. The nature and impact of future changes in monetary policies and their impact on us cannot be predicted with certainty.

Heightened Requirements for Large Bank Holding Companies and Banks
As mentioned above, the Dodd-Frank Act imposed heightened requirements on large bank holding companies and banks, and the EGRRC Act has rolled back certain provisions of the Dodd-Frank Act. In particular, the EGRRC Act increased the asset threshold for certain rules that previously applied to bank holding companies and banks with at least $10 billion in total consolidated assets. As a result of the EGRRC Act and follow-up rules, we are not currently subject to several of those heightened requirements (e.g., stress testing and a dedicated risk committee), but we will remain subject to other requirements of the Dodd-Frank Act left unaffected by the EGRRC Act, such as the requirement that we be examined, primarily by the CFPB, for compliance with federal consumer protection laws. We have established a comprehensive compliance system to ensure compliance with these rules.

COVID-19 Legislation and Regulation
Governments at the federal, state, and local levels continue to take steps to address the impact of the COVID-19 pandemic. On March 27, 2020, the historic $2 trillion federal stimulus package known as the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) was signed into law, which included $350 billion in stimulus for small businesses under the so-called Paycheck Protection Program (“PPP”), along with direct stimulus payments (i.e., “economic impact payments” or “stimulus payments”) for many eligible Americans. The initial amounts available under the Paycheck Protection Program were quickly exhausted in less than two weeks, which prompted Congress to negotiate additional funding. On April 24, 2020, the Paycheck Protection Program and Health Care Enforcement Act was signed into law to replenish funding to the Paycheck Protection Program and to provide other spending for hospitals and virus testing. Further, on July 3, 2020, the President extended the deadline for potential borrowers to apply for Paycheck Protection Program funds until August 8, 2020. And recently, on December 21, 2020, Congress passed the Consolidated Appropriations Act, which was signed into law by the President on December 27th, and included another $284 billion to fund an expansion to the PPP, subject to certain changes in eligibility requirements and program design. The Bank is taking additional loan applications, and making new loans, under the program, as most recently updated. The legislative and regulatory landscape surrounding the COVID-19 pandemic is rapidly changing, and neither the Company nor the Bank can predict with certainty the impact it will have on our operations or business.

Item 1A. Risk Factors

The following is a discussion of what we believe are the most significant risks and uncertainties that may affect our business, financial condition and future results of operations. These risks are not the only ones that we face. Other risks and uncertainties not currently known to us or currently believed to be material may harm our future business, financial condition, results of operations and prospects.

Economy and Our Markets

The effects of the COVID-19 pandemic could adversely affect our customers’ future results of operations and/or the market price of our stock.
The COVID-19 pandemic continues to rapidly evolve, as do federal, state and local efforts to address it. Both the direct effects of the pandemic and the resulting U.S. governmental responses are of an unprecedented scope as it impacts both the health and the economy of our country and the world at large. No one can predict the extent or duration of the pandemic, or its effect on the markets that we serve. Further, the ongoing efforts and impact of the government in mitigating the health and the economic effects of the pandemic cannot currently be predicted, whether on our business or as to the economy as a whole. The pandemic has thus far resulted in significant volatility in international and U.S. markets, which could adversely affect the market price of our stock. To date, the pandemic has resulted in significant business disruption and volatility in the international and domestic markets, which has led to increased volatility in the market price of our stock and stocks in general.

The Company believes it is well positioned to mitigate the potential financial impact of the COVID-19 pandemic with a strong liquidity and capital position. The Company has implemented several measures to manage through the pandemic, including:
launched a pandemic team that addresses the daily impact to our business;
proactively reaching out to, and working with customers, to assess their needs and provide funding, flexible repayment options or modifications as necessary;
designated a “command center” that supports employees so they can work with customers to provide the PPP loans;
increased monitoring of credit quality and portfolio risk for industries determined to have elevated risk; and
developed safety measures for the health of our employees including elimination of unnecessary business travel, social distancing precautions, additional wellness and education programs, and preventative cleaning practices.

Nonetheless, any future deterioration in economic conditions in the markets the Bank serves as a consequence of the pandemic, or a failure of the economy to recover from pandemic related disruptions as quickly as anticipated, could have a material adverse effect on our business, financial condition, results of operations and prospects.

Economic conditions in the market areas the Bank serves may adversely impact its earnings and could increase the credit risk associated with its loan portfolio and the value of its investment portfolio.
Substantially all of the Bank’s loans are to businesses and individuals in Montana, Idaho, Utah, Washington, Wyoming, Colorado, Arizona and Nevada, and a softening of the economies in these market areas could have a material adverse effect on its business, financial condition, results of operations and prospects. Any future deterioration in economic conditions in the markets the Bank serves could result in the following consequences, any of which could have an adverse impact, which could be material, on our business, financial condition, results of operations and prospects:
loan delinquencies may increase;
problem assets and foreclosures may increase;
collateral for loans made may decline in value, in turn reducing customers’ borrowing power;
certain securities within the investment portfolio could become other-than-temporarily impaired, requiring a write-down through earnings to fair value, thereby reducing equity;
low cost or non-interest bearing deposits may decrease; and
demand for loan and other products and services may decrease.

National and international economic and geopolitical conditions could adversely affect our future results of operations or market price of our stock.
Our business is impacted by factors such as economic, political and market conditions, broad trends in industry and finance, changes in government monetary and fiscal policies, inflation, and financial market volatility, all of which are beyond our control. National and global economies are constantly in flux, as evidenced by recent market volatility resulting from, among other things, global trade disputes and the associated imposition of tariffs in certain cases, the uncertain future relationship of the United Kingdom with the European Union (e.g., Brexit), and the ever-changing landscape of the energy and medical industries. Future economic conditions cannot be predicted, and any renewed deterioration in the economies of the nation as a whole or in our markets could have an adverse effect, which could be material, on its business, financial condition, results of operations and prospects, and could cause the market price of our stock to decline.

Competition in the Bank’s market areas may limit future success.
Commercial banking is a highly competitive business and a consolidating industry. The Bank competes with other commercial banks, credit unions, finance, insurance and other non-depository companies operating in its market areas. The Bank is subject to substantial competition for loans and deposits from other financial institutions. Some of its competitors are not subject to the same degree of regulation and restriction as the Bank while others have greater financial resources than the Bank. If the Bank is unable to effectively compete in its market areas, the Bank’s business, our results of operations and prospects could be adversely affected.

We may not be able to continue to grow organically or through acquisitions.
Historically, we have expanded through a combination of organic growth and acquisitions. If market and regulatory conditions change, we may be unable to grow organically or successfully compete for, complete, or integrate potential future acquisitions at the same pace. We have historically used our strong stock currency and capital resources to complete acquisitions. Downturns in the stock market and the market price of our stock could have an impact on future acquisitions. Furthermore, there can be no assurance that we can successfully complete such transactions, since they are subject to regulatory review and approval.


Growth through future acquisitions could, in some circumstances, adversely affect profitability or other performance measures.
In the past, we have been active in acquiring banks and we may in the future engage in selected acquisitions of additional financial institutions. There are risks associated with any such acquisitions that could adversely affect profitability and other performance measures. These risks include, among other things, incorrectly assessing the asset quality of a financial institution being acquired, discovering compliance or regulatory issues after the acquisition, encountering greater than anticipated cost and use of management time associated with integrating acquired businesses into our operations, and being unable to profitably deploy funds acquired in an acquisition. We may not be able to continue to grow through acquisitions, and if we do, there is a risk of negative impacts of such acquisitions on our operating results and financial condition.

Acquisitions may also cause business disruptions that cause the Bank to lose customers or cause customers to remove their accounts from the Bank and move to competing financial institutions. Further, acquisitions may also disrupt the Bank's ongoing businesses or create inconsistencies in standards, controls, procedures, and policies that adversely affect relationships with employees, clients, customers, and depositors. The loss of key employees during acquisitions may also adversely affect our business.

We anticipate that we might issue capital stock in connection with future acquisitions. Acquisitions and related issuances of stock may have a dilutive effect on earnings per share, book value per share, and the percentage ownership of current shareholders. In acquisitions involving the use of cash as consideration, there will be an impact on our capital position.

14


If goodwill recorded in connection with acquisitions becomes impaired, it could have an adverse impact on earnings and capital.
Accounting standards require us to account for acquisitions using the acquisition method of accounting. Under acquisition accounting, if the purchase price of an acquired company exceeds the fair value of its net assets, the excess is carried on the acquirer’s balance sheet as goodwill. In accordance with accounting principles generally accepted in the United States of America (“GAAP”), goodwill is not amortized but rather is evaluated for impairment on an annual basis or more frequently if events or circumstances indicate that a potential impairment exists. Our goodwill was not considered impaired as of December 31, 2020 and 2019; however, there can be no assurance that future evaluations of goodwill will not result in findings of impairment and write-downs, which could be material. Since we have $514 million in goodwill, representing 22 percent of our stockholders' equity, impairment of goodwill could have a material adverse effect on our business, financial condition and results of operations. Furthermore, even though it is a non-cash item, significant impairment of goodwill could subject us to regulatory limitations, including the ability to pay dividends on our common stock.

There can be no assurance we will be able to continue paying dividends on our common stock at recent levels.
We may not be able to continue paying quarterly dividends commensurate with recent levels given that our ability to pay dividends on our common stock depends on a variety of factors. The payment of dividends is subject to government regulation in that regulatory authorities may prohibit banks and bank holding companies from paying dividends that would constitute an unsafe or unsound banking practice. This is heavily based on our earnings and capital levels which currently are strong. Current guidance from the Federal Reserve provides, among other things, that dividends per share should not exceed earnings per share measured over the previous four fiscal quarters. In certain circumstances, Montana law also places limits or restrictions on a bank’s ability to declare and pay dividends. As a result, our future dividends will generally depend on the level of earnings at the Bank.

Credit and Asset Quality

The allowance for credit losses may not be adequate to cover actual loan losses, which could adversely affect earnings.
The Bank maintains an allowance for credit losses (“ACL” or “allowance”) in an amount that it believes is adequate to provide for losses in the loan portfolio. While the Bank strives to carefully manage and monitor credit quality and to identify loans that may become non-performing, at any time there are loans included in the portfolio that will result in losses, but that have not been identified as non-performing or potential problem loans. With respect to real estate loans and property taken in satisfaction of such loans (“other real estate owned” or “OREO”), the Bank can be required to recognize significant declines in the value of the underlying real estate collateral quite suddenly as values are updated through appraisals and evaluations (new or updated) performed in the normal course of monitoring the credit quality of the loans. There are many factors that can cause the value of real estate to decline, including declines in the general real estate market, changes in methodology applied by appraisers, and/or using a different appraiser than was used for the prior appraisal or evaluation. The Bank’s ability to recover on real estate loans by selling or disposing of the underlying real estate collateral is adversely impacted by declining values, which increases the likelihood the Bank will suffer losses on defaulted loans beyond the amounts provided for in the ACL. This, in turn, could require material increases in the Bank’s provision for credit losses and ACL. By closely monitoring credit quality, the Bank attempts to identify deteriorating loans before they become non-performing assets and adjust the ACL accordingly. However, because future events are uncertain, and if difficult economic conditions occur, there may be loans that deteriorate to a non-performing status in an accelerated time frame. As a result, future additions to the ACL may be necessary beyond the levels commensurate with any loan growth. Because the loan portfolio contains a number of loans with relatively large balances, the deterioration of one or a few of these loans may cause a significant increase in non-performing loans, requiring an increase to the ACL. Additionally, future significant additions to the ACL may be required based on changes in the mix of loans comprising the portfolio, changes in the financial condition of borrowers, which may result from changes in economic conditions, or changes in the assumptions used in determining the ACL. Additionally, federal and state banking regulators, as an integral part of their supervisory function, periodically review the Bank’s loan portfolio and the adequacy of the ACL. These regulatory authorities may require the Bank to recognize further provision for credit losses or charge-offs based upon their judgments, which may be different from the Bank’s judgments. Any increase in the ACL could have an adverse effect, which could be material, on our financial condition and results of operations.

The Bank’s loan portfolio mix increases the exposure to credit risks tied to deteriorating conditions.
The loan portfolio contains a high percentage of commercial, commercial real estate, real estate acquisition and development loans in relation to the total loans and total assets. These types of loans have historically been viewed as having more risk of default than residential real estate loans or certain other types of loans or investments. In fact, the FDIC has issued pronouncements alerting banks of its concern about banks with a heavy concentration of commercial real estate loans. These types of loans also typically are larger than residential real estate loans and other commercial loans. Because the Bank’s loan portfolio contains a significant number of commercial and commercial real estate loans with relatively large balances, the deterioration of one or more of these loans may cause a significant increase in non-performing loans. An increase in non-performing loans could result in a loss of earnings from these loans, an increase in the provision for credit losses, or an increase in charge-offs, which could have a material adverse impact on our results of operations and financial condition.

15


The Bank has a high concentration of loans secured by real estate, so any future deterioration in the real estate markets could require material increases in the ACL and adversely affect our financial condition and results of operations.
The Bank has a high degree of concentration in loans secured by real estate. Any future deterioration in the real estate markets could adversely impact borrowers’ ability to repay loans secured by real estate and the value of real estate collateral, thereby increasing the credit risk associated with the loan portfolio. The Bank’s ability to recover on these loans by selling or disposing of the underlying real estate collateral would be adversely impacted by any decline in real estate values, which increases the likelihood that the Bank will suffer losses on defaulted loans secured by real estate beyond the amounts provided for in the ACL. This, in turn, could require material increases in the ACL which would adversely affect our financial condition and results of operations.

Non-performing assets could increase, which could adversely affect our results of operations and financial condition.
The Bank may experience increases in non-performing assets in the future. Non-performing assets (which include OREO) adversely affect our financial condition and results of operations in various ways. The Bank does not record interest income on non-accrual loans or OREO, thereby adversely affecting its earnings. When the Bank takes collateral in foreclosures and similar proceedings, it is required to mark the related asset to the then fair value of the collateral, less estimated cost to sell, which may result in a charge-off of the value of the asset and lead the Bank to increase the provision for credit losses. An increase in the level of non-performing assets also increases the Bank’s risk profile and may impact the capital levels its regulators believe are appropriate in light of such risks. Further decreases in the value of these assets, or the underlying collateral, or in these borrowers’ performance or financial condition, whether or not due to economic and market conditions beyond the Bank’s control, could adversely affect our business, results of operations and financial condition, perhaps materially. In addition to the carrying costs to maintain OREO, the resolution of non-performing assets increases the Bank’s loan administration costs generally, and requires significant commitments of time from management and our directors, which reduces the time they have to focus on profitably growing our business.

A decline in the fair value of the Bank’s investment portfolio could adversely affect earnings and capital.
The fair value of the Bank’s debt securities could decline as a result of factors including changes in market interest rates, tax reform, credit quality and credit ratings, lack of market liquidity and other economic conditions. For debt securities in an unrealized loss position, the Company may be required to record an allowance for credit losses or write down the security depending on the type of security and the circumstances. Any such impairment charge would have an adverse effect, which could be material, on our results of operations and financial condition, including its capital.

While we believe that the terms of our debt securities have been kept relatively short, we are subject to elevated interest rate risk exposure if rates were to increase sharply. Further, debt securities present a different type of asset quality risk than the loan portfolio. While we believe a relatively conservative management approach has been applied to the investment portfolio, there is always potential loss exposure under changing economic conditions.

The Bank is subject to environmental liability risk associated with our lending activities.
A significant portion of our loan portfolio is secured by real estate, and we could become subject to environmental liabilities with respect to one or more of these properties. During the ordinary course of business, we may foreclose on and take title to properties securing defaulted loans. In doing so, there is a risk that hazardous or toxic substances could be found on these properties. If hazardous conditions or toxic substances are found on these properties, we may be liable for remediation costs, as well as for personal injury and property damage, civil fines and criminal penalties regardless of when the hazardous conditions or toxic substances first affected any particular property. Environmental laws may require us to incur substantial expenses to address unknown liabilities and may materially reduce the affected property’s value or limit our ability to use or sell the affected property. In addition, future laws or more stringent interpretations or enforcement policies with respect to existing laws may increase our exposure to environmental liability. Although we have policies and procedures to perform an environmental review before initiating any foreclosure on nonresidential real property, these reviews may not be sufficient to detect all potential environmental hazards. The remediation costs and any other financial liabilities associated with an environmental hazard could have a material adverse effect on us.

We face competition from technologies used to support and enable banking and financial services.
Emerging technologies and advances and the growth of e-commerce have lowered geographic and monetary barriers of other financial institutions, made it easier for non-depository institutions to offer products and services that traditionally were banking products and allowed non-traditional financial service providers and technology companies to compete with traditional financial service companies in providing electronic and internet-based financial solutions and services, including electronic securities trading, marketplace lending, financial data aggregation and payment processing, including real-time payment platforms. Further, clients may choose to conduct business with other market participants who engage in business or offer products in areas we deem speculative or risky, such as cryptocurrencies. Increased competition may negatively affect our earnings by creating pressure to lower prices or credit standards on our products and services requiring additional investment to improve the quality and delivery of our technology and/or reducing our market share, or affecting the willingness of our clients to do business with us.

Interest Rates, Operations and Risk Management

Fluctuating interest rates can adversely affect profitability.
The Bank’s profitability is dependent to a large extent upon net interest income, which is the difference (or “spread”) between the interest earned on loans, investment securities and other interest earning assets and interest paid on deposits, borrowings, and other interest bearing liabilities. Because of the differences in maturities and repricing characteristics of interest earning assets and interest bearing liabilities, changes in interest rates do not produce equivalent changes in interest income earned on interest earning assets and interest paid on interest bearing liabilities. Accordingly, fluctuations in interest rates could adversely affect the Bank’s interest rate spread, and, in turn, profitability. The Bank seeks to manage its interest rate risk within well established policies and guidelines. Generally, the Bank seeks an asset and liability structure that insulates net interest income from large deviations attributable to changes in market rates. However, the Bank’s structures and practices to manage interest rate risk may not be effective in a highly volatile rate environment. While the Federal Reserve increased the federal funds target range seven times in 2017 and 2018, the target rate was decreased three times in 2019 and 2020 saw a return to target rates at or near historical lows as part of the fiscal response to the pandemic.

We may be impacted by the retirement of London Interbank Offered Rate (“LIBOR”) as a reference rate.
In July 2017, the United Kingdom Financial Conduct Authority announced that LIBOR may no longer be published after 2021. LIBOR is used extensively in the U.S and globally as a “benchmark” or “reference rate” for various commercial and financial contracts. In response, the Alternative Reference Rates Committee (“ARRC”), made up of financial and capital market institutions, was convened to address the replacement of LIBOR in the U.S. The ARRC identified a potential successor to LIBOR in the Secured Overnight Financing Rate (“SOFR”) and crafted a plan to facilitate the transition. However, there are significant conceptual and technical differences between LIBOR and SOFR. The Financial Stability Oversight Committee has stated that the end or waning use of LIBOR has the potential to significantly disrupt trading in many important types of financial contracts.

At this time, no consensus exists as to what rate or rates may become acceptable alternatives to LIBOR and it is impossible to predict the effect of any such alternatives on the value of LIBOR-based securities and variable rate loans, subordinated debentures or other securities or financial arrangements. The replacement of LIBOR with one or more alternative rates may impact the availability and cost of hedging instruments and borrowings, including the rates we pay on our subordinated debentures and derivative financial instruments. If LIBOR rates are no longer available, and we are required to implement substitute indices for the calculation of interest rates under contracts or financial instruments to which we are a party, we may incur significant expenses in effecting the transition.

Our business is heavily dependent on the services of members of the senior management team.
We believe our success to date has been substantially dependent on its executive management team. In addition, our unique model relies upon the Presidents of our separate Bank divisions, particularly in light of our decentralized management structure in which such Bank divisions have significant local decision-making authority. The unexpected loss of any of these persons could have an adverse effect on our business and future growth prospects.

Our business is subject to the risks of earthquakes, floods, fires, and other natural catastrophes.
With Bank branches located in Montana, Idaho, Utah, Washington, Wyoming, Colorado, Arizona and Nevada, our business could be affected by a major natural catastrophe, such as a fire, flood, earthquake, or other natural disaster. The occurrence of any of these events may result in a prolonged interruption of our business, which could have a material adverse effect on our financial condition and operations.


Our future performance will depend on our ability to respond timely to technological change.
The financial services industry is experiencing rapid technological changes with frequent introductions of new technology-driven products and services. The effective use of technology increases efficiency and enables financial institutions to better serve customers and to reduce costs. Our future success will depend upon our ability to address the needs of our customers by using technology to provide products and services that will satisfy customer demands for convenience, as well as create additional efficiencies in our operations. We may not be able to effectively implement new technology-driven products or services, or be successful in marketing these products and services. Additionally, the implementation of technological changes and upgrades to maintain current systems and integrate new ones may cause services interruptions, transaction processing errors and system conversion delays and may cause us to fail to comply with applicable laws. There can be no assurance that we will be able to successfully manage the risks associated with increased dependency on technology.

A failure in or breach of the Bank’s operational or security systems, or those of the Bank’s third party service providers, including as a result of cyber attacks, could disrupt business, result in the disclosure or misuse of confidential or proprietary information, damage our reputation, increase costs and cause losses.
In the normal course of its business, the Bank collects, processes and retains sensitive and confidential customer information. Despite the security measures we have in place, our facilities may be vulnerable to cyber-attacks, security breaches, acts of vandalism, computer viruses, misplaced or lost data, programming or human errors, and other similar events.

17


Information security risks for financial institutions such as the Bank have increased recently in part because of new technologies, the use of the Internet and telecommunications technologies, including mobile devises, to conduct financial and other business transactions and the increased sophistication and activities of organized crime, perpetrators of fraud, hackers, terrorists and others. In addition to cyber attacks or other security breaches involving the theft of sensitive and confidential information, hackers have engaged in attacks against financial institutions designed to disrupt key business services such as customer-facing web sites. We are not able to anticipate or implement effective preventative measures against all security breaches of these types. Although the Bank employs detection and response mechanisms designed to contain and mitigate security incidents, early detection may be thwarted by sophisticated attacks and malware designed to avoid detection, which continue to evolve.

Additionally, the Bank faces the risk of operational disruption, failure, termination or capacity constraints of any of the third parties that facilitate its business activities, including exchanges, clearing agents, clearing houses or other financial intermediaries. Such parties could also be the source of an attack on, or breach of, the Bank’s operational systems.

Any failures, interruptions or security breaches in the Bank’s information systems could damage its reputation, result in a loss of customer business, result in a violation of privacy or other laws, or expose us to civil litigation, regulatory fines or losses not covered by insurance.

We could suffer operational, reputational and financial harm if we fail to properly anticipate and manage risk.
We use models and strategies to forecast losses, project revenue, measure and assess capital requirements for credit, market, operational and strategic risks, and assess and control our operations and financial condition. These models require oversight, ongoing monitoring, and periodic reassessment. Models are subject to inherent limitations due to the use of historical trends and simplifying assumptions, uncertainty regarding economic and financial outcomes, and emerging risks from the use of applications that may rely on artificial intelligence. Our models and strategies may not be adequate due to limited historical data and shocks caused by extreme or unanticipated market changes, especially during severe market downturns or stress events. Regardless of the steps we take to ensure effective controls, governance, monitoring and testing, and implement new risk management tools, we could suffer operational, reputational and financial harm if our models and strategies and other risk management tools fail to properly anticipate and manage current and evolving risks.

We have various anti-takeover measures that could impede a takeover.
Our articles of incorporation include certain provisions that could make it more difficult to acquire us by means of a tender offer, a proxy contest, merger or otherwise. These provisions include a requirement that any “Business Combination” (as defined in the articles of incorporation) be approved by at least 80 percent of the voting power of the then outstanding shares, unless it is either approved by our Board or certain price and procedural requirements are satisfied. In addition, the authorization of preferred stock, which is intended primarily as a financing tool and not as a defensive measure against takeovers, may potentially be used by management to make more difficult uninvited attempts to acquire control of us. These provisions may have the effect of lengthening the time required to acquire control of us through a tender offer, proxy contest or otherwise, and may deter any potentially unfriendly offers or other efforts to obtain control of us. This could deprive our shareholders of opportunities to realize a premium for their common stock in the Company, even in circumstances where such action is favored by a majority of our shareholders.

Regulatory Matters

We are subject to heightened regulatory requirements related to our having exceeded $10 billion in assets.
Because our total consolidated assets exceeded $10 billion during the first quarter of 2018, the Dodd-Frank Act and its implementing regulations impose additional requirements on bank holding companies with $10 billion or more in total assets, including compliance with specific sections of the Federal Reserve's prudential oversight requirements. The Durbin Amendment, which was passed as part of the Dodd-Frank Act, instructed the Federal Reserve to establish rules limiting the amount of interchange fees that can be charged to merchants for debit card processing. The Federal Reserve's Final rules contained several key pieces, including in relevant part an interchange fee cap, certain fraud prevention adjustments, and, most notably, an exemption from the interchange fee cap for small issuers. Issuers with less than $10 billion in total assets (as of the end of the previous calendar year) are exempt from the Federal Reserve's interchange fee cap. As our total assets exceeded $10 billion, the interchange fee cap of the Durbin Amendment negatively affected the interchange income the Bank receives from electronic payment transactions. The interchange fee cap became effective to us commencing in July of 2019.

In addition, banks with $10 billion or more in total assets are primarily examined by the CFPB with respect to compliance with various federal consumer financial protection laws and regulations. As a fairly new agency with evolving regulations and practices, it is uncertain as to how the CFPB's examinations and regulatory authority may impact our business.

Changes in accounting standards could materially impact our financial statements.
Periodically, the Financial Accounting Standards Board (“FASB”) and the SEC change the financial accounting and reporting standards that govern the preparation of our financial statements. These changes can materially impact how we record and report our
18


financial condition and results of operations. For information regarding the impact of recently issued accounting standards, see “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

The FDIC has adopted a final rule to increase the federal Deposit Insurance Fund, including additional future premium increases and special assessments.
On March 15, 2016, the FDIC adopted a final rule to increase insurance premiums and has imposed special assessments to rebuild and maintain the DIF, and any additional future premium increases or special assessments could have a material adverse effect on our business, financial condition, and results of operations.

The Dodd-Frank Act broadened the base for FDIC insurance assessments. In addition, the Dodd-Frank Act established 1.35 percent as the minimum DIF reserve ratio. The FDIC has determined that the fund reserve ratio should be 2.0 percent (which is beyond what is required by law) and has adopted a plan under which it will meet the statutory minimum fund reserve ratio of 1.35 percent. The Dodd-Frank Act made banks with $10 billion or more in total assets responsible for the increase from 1.15 percent to 1.35 percent. The increase is effective for banks in the first quarter following four consecutive quarters of total consolidated assets exceeding $10 billion. Since the Bank exceeded the $10 billion asset threshold in the first quarter of 2018, the increase in deposit insurance assessments to be paid by the Bank was effective in the first quarter of 2019. Additionally, under the FDIC’s assessment system for determining payments to the DIF, insured depository institutions with more than $10 billion in assets are assessed under a “scorecard” system.

Additional information regarding this matter is set forth under the section captioned “Deposit Insurance” within “Supervision and Regulation” in “Item 1. Business.”

We operate in a highly regulated environment and changes or increases in, or supervisory enforcement of, banking or other laws and regulations or governmental fiscal or monetary policies could adversely affect us.
We are subject to extensive regulation, supervision and examination by federal and state banking regulators. In addition, as a publicly-traded company, we are subject to regulation by the SEC. Any change in applicable regulations or federal, state or local legislation or in policies or interpretations or regulatory approaches to compliance and enforcement, income tax laws and accounting principles could have a substantial impact on us and our operations. Changes in laws and regulations may also increase expenses by imposing additional fees or taxes or restrictions on operations. Additional legislation and regulations that could significantly affect powers, authority and operations may be enacted or adopted in the future, which could have a material adverse effect on our financial condition and results of operations. Failure to appropriately comply with any such laws, regulations or principles could result in sanctions by regulatory agencies or damage to our reputation, all of which could adversely affect our business, financial condition or results of operations.

Regulators have significant discretion and authority to prevent or remedy unsafe or unsound practices or violations of laws or regulations by financial institutions and bank holding companies in the performance of their supervisory and enforcement duties. Existing and proposed federal and state laws and regulations restrict, limit and govern all aspects of our activities and may affect our ability to expand our business over time, may result in an increase in our compliance costs, and may affect our ability to attract and retain qualified executive officers and employees. The exercise of regulatory authority may have a negative impact on our financial condition and results of operations, including limiting the types of financial services and products we may offer or increasing the ability of non-banks to offer competing financial services and products. Additionally, our business is affected significantly by the fiscal and monetary policies of the federal government and its agencies, including the Federal Reserve.

We cannot accurately predict the full effects of recent legislation or the various other governmental, regulatory, monetary and fiscal initiatives which have been and may be enacted on the financial markets and on us. The terms and costs of these activities, or the failure of these actions to help stabilize the financial markets, asset prices, market liquidity and a continuation or worsening of current financial market and economic conditions could materially and adversely affect our business, financial condition, results of operations, and the trading price of our common stock.

Item 6. Selected Financial Data

Non-GAAP Financial Measures
In addition to the results presented in accordance with GAAP, this Annual Report on Form 10-K contains certain non-GAAP financial measures. The Company believes that providing these non-GAAP financial measures provides investors with information useful in understanding and comparing the Company’s financial performance, performance trends, and financial position. While the Company uses these non-GAAP measures in its analysis of the Company’s performance, this information should not be considered an alternative to measurements required by GAAP. The following table provides a reconciliation of certain GAAP financial measures to non-GAAP financial measures.

 Year ended December 31, 2017
(Dollars in thousands, except per share data)GAAPTax Act AdjustmentNon-GAAP
Federal and state income tax expense$64,625 (19,699)44,926 
Net income$116,377 19,699 136,076 
Basic earnings per share$1.50 0.25 1.75 
Diluted earnings per share$1.50 0.25 1.75 
Return on average assets1.20 %0.21 %1.41 %
Return on average equity9.80 %1.66 %11.46 %
Dividend payout ratio76.00 %(10.86 %)65.14 %
Effective income tax rate35.70 %(10.88 %)24.82 %

The reconciling item between the GAAP and non-GAAP financial measures was due to the one-time tax expense of $19.7 million during the year ended December 31, 2017. The one-time tax expense was driven by The Tax Cuts and Jobs Act (“Tax Act”) and the change in the federal marginal corporate income tax rate from 35 percent to 21 percent for 2018 and future years, which resulted in the revaluation of its deferred tax assets and deferred tax liabilities (“net deferred tax asset”). The Company believes the financial results are more comparable excluding the impact of the revaluation of the net deferred tax asset.

Basic earnings per share is calculated by dividing net income by average outstanding shares and diluted earnings per share is calculated by dividing net income by diluted average outstanding shares. The one-time tax expense of $19.7 million was included in determining income for both the GAAP basic earnings per share and the GAAP diluted earnings per share. Conversely, the one-time tax expense of $19.7 million was excluded in determining income for both the non-GAAP basic earnings per share and the non-GAAP diluted earnings per share. Average outstanding shares of 77,537,664 was used in the GAAP and non-GAAP basic earnings per share for the year ended December 31, 2017. Diluted average outstanding shares of 77,607,605 was used in the GAAP and non-GAAP diluted earnings per share for the year ended December 31, 2017.

The return on average assets ratio is calculated by dividing net income by average assets and the return on average equity ratio is calculated by dividing net income by average equity. The one-time tax expense of $19.7 million was included in determining income for both the GAAP return on average assets and the GAAP return on average equity. Conversely, the one-time tax expense of $19.7 million was excluded in determining income for both the non-GAAP return on average assets and the non-GAAP return on average equity. Average assets of $9.678 billion was used in the GAAP and non-GAAP return on average assets ratios for the year ended December 31, 2017. Average equity of $1.188 billion was used in the GAAP and non-GAAP return on average equity ratios for the year ended December 31, 2017.

The dividend payout ratio is calculated by dividing dividends declared per share by basic earnings per share. The non-GAAP dividend payout ratio uses the non-GAAP basic earnings per share for calculating the ratio.

The effective income tax rate is calculated by dividing federal and state income tax expense by income before income taxes. The non-GAAP effective income tax rate uses the non-GAAP federal and state income tax expense of $44.9 million for calculating the rate.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion is intended to provide a more comprehensive review of the Company’s operating results and financial condition than can be obtained from reading the Consolidated Financial Statements alone. The discussion should be read in conjunction with the Consolidated Financial Statements and the notes thereto included in “Item 8. Financial Statements and Supplementary Data.”

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This Annual Report on Form 10-K contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995.

These forward-looking statements are based on current beliefs and expectations of management and are inherently subject to significant business, economic and competitive uncertainties and contingencies, many of which are beyond the Company’s control. In addition, these forward-looking statements are subject to assumptions with respect to future business strategies and decisions that are subject to change. The following factors, among others, could cause actual results to differ materially from the anticipated results (express or implied) or other expectations in the forward-looking statements, including those factors set forth under “Risk Factors” and in other sections in this Annual Report on Form 10-K, or the documents incorporated by reference:
the risks associated with lending and potential adverse changes of the credit quality of loans in the Company’s portfolio;
changes in trade, monetary and fiscal policies and laws, including interest rate policies of the Board of Governors of the Federal Reserve System, which could adversely affect the Company’s net interest income and profitability;
changes in the cost and scope of insurance from the FDIC and other third parties;
the scope, duration, and effects of the COVID-19 pandemic, including on the Company’s credit quality and operations as well as its impact on general economic conditions;
legislative or regulatory changes, including actions taken by governmental authorities in response to the COVID-19 pandemic;

changes in interest rates, deposit flows, costs of funds, demand for loan products and the demand for financial services in each case as may be further affected by the COVID-19 pandemic;
the reputation of banks and the financial services industry could deteriorate, which could adversely affect the Company's ability to obtain and maintain customers;
competition among financial institutions in the Company's markets may increase significantly, including due to the entry of new participants that rely on emerging technologies to make loans and acquire deposits which may not be as heavily regulated as we are;
the risks presented by continued public stock market volatility, which could adversely affect the market price of the Company’s common stock and the ability to grow the Company through acquisitions or raise capital in the future;
the projected business and profitability of an expansion or the opening of a new branch could be lower than expected;
consolidation in the financial services industry in the Company’s markets resulting in larger financial institutions with greater resources and decreasing opportunities to pursue acquisitions;
dependence on the CEO, the senior management team and the Presidents of Glacier Bank divisions;
material failure, potential interruption or breach in security of the Company’s systems or those of our vendors and technological changes or changes in actors and techniques used by cyber criminals which could expose us to new risks (e.g., cybersecurity), fraud or system failures;
natural disasters, including fires, floods, earthquakes, and other unexpected events;
the Company’s success in managing risks involved in the foregoing; and
the effects of any reputational damage to the Company resulting from any of the foregoing.

MANAGEMENT’S DISCUSSION AND ANALYSIS
OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
YEAR ENDED DECEMBER 31, 2020 COMPARED TO DECEMBER 31, 2019

Highlights and Overview
The Company’s oversight of strategy was salient following the onset of the COVID-19 pandemic. The Company worked diligently to assess the impact of the pandemic on all facets of the Company, examining financial impacts, the ability to meet customer needs, the effect of regulatory actions to combat the pandemic on our operations, measures taken to protect the health and safety of our employees and customers and our business continuity strategy. The Company remained engaged on each of these initiatives throughout the year by receiving regular updates from management and providing input and oversight. Through continuous monitoring, the Company was able to take actions to ensure that disruptions to customers were minimal while preventing any furloughs, layoffs, or reductions in compensation for our employees.

In order to meet the needs of its customers impacted by the pandemic, the Company provided funding, flexible repayment options or modifications if necessary. During the year, the Company modified 3,054 loans in the amount of $1.515 billion primarily with short-term payment deferrals under six months. As of year end, only $94.9 million of the modifications remain in the deferral period. In addition, the Company originated Small Business Association (“SBA”) Paycheck Protection Program (“PPP”) loans for small businesses in its communities. The Company originated 16,090 PPP in the amount of $1.472 billion during the current year of which $539 million, or 37 percent, were forgiven by the SBA during the year. In the coming year, the Company will continue to remain flexible in responding to changing conditions due to COVD-19 in the markets it serves and remains optimistic it can continue to deliver profitable results.

During 2020, the Company acquired all the outstanding stock of SBAZ, a community bank based in Lake Havasu City, Arizona with total assets of $745 million. SBAZ provides banking services to individuals and business in Arizona with ten locations in Bullhead City, Cottonwood, Kingman, Lake Havasu City, Phoenix, Prescott Valley and Prescott. Upon closing of the transaction, SBAZ was merged into the Company’s Foothills Bank division, which expanded the Company’s footprint in Arizona to cover all major markets and established it as a leading community bank in Arizona. See Note 23 in the Consolidated Financial Statements in “Item 8. Financial Statements and Supplementary Data” for additional information regarding these acquisitions.

The Company ended the year at $18.504 billion in assets, which was a 35 percent increase over the prior year and was driven primarily by the current year acquisition along with increases from the PPP loans and debt securities purchased as a result of excess liquidity. Organic loan growth was $1.158 billion, or 12 percent, during the current year and excluding the PPP loans, organic loan growth was $249 million, or 3 percent. The Company experienced another great year in core deposit which organically increased $3.433 billion, or 32 percent, with non-interest bearing deposits increasing $1.616 billion, or 44 percent, during the year.

Tangible stockholders’ equity increased $296 million, or $2.60 per share, as a result of earnings retention, an increase in other comprehensive income (“OCI”) and Company stock issued in connection with the current year acquisition. The Company increased its total regular quarterly dividends declared from $1.11 per share during 2019 to $1.18 per share in 2020. During the current year, S&P Dow Jones Indices selected the Company to transition from the S&P SmallCap 600® to the S&P MidCap 400®. The S&P MidCap 400® index consist of 400 companies that are chosen with regard to market capitalizing, liquidity and industry representation.

The Company continued to decrease its non-performing assets and ended the year at $35.4 million, or 0.19 percent of assets, which was a decrease of $2.0 million, or 5 percent, from the prior year end. In addition, early stage delinquencies (accruing 30-89 days past due) as a percentage of loans at December 31, 2020 was 0.20 percent compared to 0.24 percent at the prior year end.

The Company had record net income for the year of $266 million, which was an increase of $55.9 million, or 27 percent, over the prior year net income of $211 million. Diluted earnings per share for the year was $2.81, an increase of 18 percent, from the 2019 diluted earnings per share of $2.38. The improvement in net income for 2020 was due to recent acquisitions, organic growth, the significant increase in commercial interest income from the PPP loans and the record year for gain on sale of loans. The Company's net interest margin for 2020 was 4.09 percent, a 30 basis points decrease from the net interest margin of 4.39 percent from 2019 which was primarily driven by the low rate environment and the shift in the earning asset mix from higher yielding loans to lower yielding debt securities.

Looking forward, the Company’s future performance will depend on many factors including economic conditions in the markets the Company serves, interest rate changes, increasing competition for deposits and loans, loan quality and growth, the impact and successful integration of acquisitions, and managing regulatory burden.

Total debt securities of $5.528 billion at December 31, 2020 increased $2.728 billion, or 97 percent, from the prior year end. During 2020, the Company purchased debt securities with excess liquidity from the increase in core deposits and SBA forgiveness of PPP loans. Debt securities represented 30 percent of total assets at December 31, 2020 compared to 20 percent of total assets at December 31, 2019. The loan portfolio of $11.123 billion increased $1.610 billion, or 17 percent during the current year. Excluding the PPP loans and the SBAZ acquisition, the loan portfolio increased $249 million, or 3 percent, from the prior year end with the largest increase in commercial real estate loans which increased $401 million, or 7 percent.

Excluding the SBAZ acquisition, core deposits increased $3.433 billion, or 32 percent, from the prior year end, with non-interest bearing deposits increasing $1.616 billion, or 44 percent. The current year significant increase in deposits was attributable to a number of factors including the PPP loan proceeds deposited by customers and the increase in customer savings. Non-interest bearing deposits were 37 percent of total core deposits at December 31, 2020 compared to 34 percent at December 31, 2019.

Wholesale deposits of $38.1 million at December 31, 2020 decreased $15.2 million, or 28 percent, from the prior year end. Federal Home Loan Bank (“FHLB”) advances were paid off in full as of December 31, 2020, which resulted in a decrease of $38.6 million from the prior year. The reduction in wholesale deposits and FHLB advances were the result of the significant increase in core deposits which funded loans and debt security growth. Wholesale deposits and FHLB advances will continue to fluctuate as necessary for balance sheet growth and to supplement liquidity needs of the Company.

Tangible book value per common share$18.21 $15.61 $2.60 17 %

Tangible stockholders’ equity increased $296 million over the prior year, which was the result of $112 million of Company stock issued for the acquisitions of SBAZ and an increase in other comprehensive income and earnings retention. These increases more than offset the increase in goodwill and core deposit intangible associated with the acquisition. The current year decrease in both the stockholders’ equity to total assets ratio and the tangible stockholders’ equity to total tangible assets ratio was primarily the result of adding $909 million of PPP loans and $2.7 billion in debt securities. Tangible book value per common share of $18.21 at the current year end increased $2.60 per share from a year ago.

Net Interest Income
Net-interest income of $600 million for 2020 increased $96.3 million, or 19 percent, over 2019. Interest income of $627 million for the current year increased $80.9 million, or 15 percent, from the prior year and was primarily attributable to a $67.4 million increase in income from commercial loans, including $38.2 million from the PPP loans. Additionally, interest income on debt securities increased $14.1 million, or 17 percent, over the prior year which resulted from the increased volume of debt securities. Interest expense of $27.3 million for 2020 decreased $15.5 million, or 36 percent over the prior year primarily as a result of decreased higher cost FHLB advances combined with the decrease in the cost of deposits and borrowings. The total funding cost (including non-interest bearing deposits) for 2020 was 19 basis points, which decreased 20 basis points compared to 39 basis points in 2019.

The net interest margin as a percentage of earning assets, on a tax-equivalent basis, during 2020 was 4.09 percent, a 30 basis points decrease from the net interest margin of 4.39 percent for 2019. The core net interest margin, excluding 3 basis points of discount accretion and, 1 basis point of non-accrual interest, was 4.05 compared to a core margin of 4.30 percent in the prior year. Although the Company was successful in reducing the total, cost of funding, it was not enough to outpace the decrease in yields on loans and debt securities driven by the current interest rate environment and the shift in the earning asset mix from higher yielding loans to lower yielding debt securities.

Non-interest Income
Non-interest income of $173 million for 2020 increased $42.1 million, or 32 percent, over last year. Service charges and other fees of $52.5 million for 2020 decreased $15.4 million, or 23 percent, from the prior year as a result of a decrease in overdraft activity and the impact of the Durbin Amendment which outpaced the additional fees from increased customer accounts. As of July 1, 2019, the Company became subject to the Durbin Amendment which established limits on the amount of interchange fees that can be charged to merchants for debit card processing. Miscellaneous loan fees increased $2.0 million, or 38 percent, driven by increased activity primarily in residential real estate. Gain of $99.5 million on the sale of loans for 2020, increased $65.4 million, or 192 percent, compared to the prior year as a result of a significant increase in purchase and refinance activity driven by the decrease in interest rates. Other income increased $3.4 million from the prior year and was primarily the result of a gain of $2.4 million on the sale of a former branch building in the first quarter of 2020.

31


During the prior year third quarter, the Company terminated $260 million notional pay-fixed interest rate swaps and corresponding debt along with the sale of $308 million of available-for-sale debt securities. Sale of the investment securities resulted in a gain of $13.8 million in the prior year third quarter. Offsetting the gain was a $10 million loss recognized on the early termination of the interest swaps and a $3.5 million write-off of the remaining unamortized deferred prepayment penalties on FHLB borrowings.

Total non-interest expense of $405 million for 2020 increased $29.9 million, or 8 percent, over the prior year. Compensation and employee benefits for 2020 increased $30.3 million, or 14 percent, from last year due to the increased number of employees from acquisitions and organic growth, increased real estate commissions, increased performance-related compensation and annual salary increases which more than offset the $8.9 million deferral of compensation cost from the PPP loans in the current year and the $5.4 million of stock compensation expense in the prior year from the Heritage acquisition. Occupancy and equipment expense for current year increased $3.2 million, or 9 percent from the prior year primarily from increased cost from acquisitions. Data processing expense for the current year increased $3.7 million, or 22 percent, from the prior year as a result of the increased costs from acquisitions along with increased investment in technology infrastructure. Regulatory assessment and insurance for the current year increased $885 thousand from the prior year primarily due to $2.5 million in Small Bank Assessment credits applied in 2019 that more than offset the $530 thousand in Small Bank Assessment credits applied in 2020 and the current year waiver of the State of Montana regulatory assessment. Other expenses of $66.8 million, increased $4.0 million, or 6 percent, from the prior year, including $1.9 million for third party consulting regarding improvements in technology, product and service offerings. Acquisition-related expenses were $7.8 million in the current year compared to $8.5 million in the prior year.

The prior year $13.5 million loss on termination of hedging activities included a $3.5 million write-off of the remaining unamortized deferred prepayment penalties on FHLB debt and a $10 million loss on the termination of pay-fixed interest rate swaps with notional amount of $260 million in the prior year third quarter.
