Alerus Financial Corporation and Subsidiaries

Notes to Consolidated Financial Statements (Unaudited)

NOTE 1 Significant Accounting Policies

Organization

Alerus Financial Corporation, or the Company, is a financial holding company organized under the laws of the state of Delaware. The Company and its subsidiaries operate as a diversified financial services company headquartered in Grand Forks, North Dakota. Through its subsidiary, Alerus Financial, National Association, or the Bank, the Company provides financial solutions to businesses and consumers through four distinct business lines—banking, retirement and benefit services, wealth management, and mortgage.

Initial Public Offering

On September 17, 2019, the Company sold 2,860,000 shares of common stock in its initial public offering. On September 25, 2019, the Company sold an additional 429,000 shares of common stock pursuant to the exercise in full, by the underwriters, of their option to purchase additional shares. The aggregate offering price for the shares sold by the Company was $69.1 million, and after deducting $4.7 million of underwriting discounts and $1.6 million of offering expenses paid to third parties, the Company received total net proceeds of $62.8 million.

Basis of Presentation

The accompanying unaudited consolidated financial statements and notes thereto of the Company have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission, or SEC, and conform to practices within the banking industry and include all of the information and disclosures required by generally accepted accounting principles in the United States of America, or GAAP, for interim financial reporting. The accompanying unaudited consolidated financial statements reflect all adjustments (consisting only of normal recurring adjustments) that are necessary for a fair presentation of financial results for the interim periods presented. The results of operations for the interim periods are not necessarily indicative of the results for the full year or any other period. The Company has also evaluated all subsequent events for potential recognition and disclosure through the date of the filing of this Quarterly Report on Form 10-Q. These interim unaudited financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto as of and for the year ended December 31, 2019, included in the Company’s Annual Report on Form 10-K filed with the SEC on March 26, 2020.

Principles of Consolidation

The accompanying unaudited consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. The Company’s principal operating subsidiary is the Bank.

In the normal course of business, the Company may enter into a transaction with a variable interest entity, or VIE. VIE’s are legal entities whose investors lack the ability to make decisions about the entity’s activities, or whose equity investors do not have the right to receive the residual returns of the entity. The applicable accounting guidance requires the Company to perform ongoing quantitative and qualitative analysis to determine whether it must consolidate any VIE. The Company does not have any ownership interest in, or exert any control, over any VIE, and thus no VIE’s are included in the consolidated financial statements.

Use of Estimates

The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.

8

Table of Contents

Material estimates that are particularly susceptible to significant change in the near term include the valuation of investment securities, determination of the allowance for loan losses, valuation of reporting units for the purpose of testing goodwill and other intangible assets for impairment, valuation of deferred tax assets, and fair values of financial instruments.

Reclassifications

Certain items previously reported have been reclassified to conform to the current period’s reporting format. Such reclassifications did not affect net income or stockholders’ equity.

Other Information

On March 11, 2020, the World Health Organization declared the spread of Coronavirus Disease 2019, or COVID-19, a worldwide pandemic. The COVID-19 pandemic is having significant effects on global markets, supply chains, businesses, and communities. Specific to the Company, COVID-19 has impacted various parts of its 2020 operations and financial results, including, but not limited to, additional loan loss reserves, costs for emergency preparedness, or potential shortages of personnel. Management believes the Company is taking appropriate actions to mitigate, to the extent possible, the negative impact. However, the full impact of COVID-19 is currently unknown and cannot be reasonably estimated as the events are continuing to unfold as the year progresses.

In March 2020, various regulatory agencies, including the Board of Governors of the Federal Reserve System and the Federal Deposit Insurance Corporation, or the agencies, issued an interagency statement on loan modifications and reporting for financial institutions working with customers affected by COVID-19. The interagency statement was effective immediately and impacted accounting for loan modifications. Under Accounting Standards Codification 310-40, “Receivables – Troubled Debt Restructurings by Creditors,” or ASC 310-40, a restructuring of debt constitutes a troubled debt restructuring, or TDR, if the creditor for economic or legal reasons related to the debtor’s financial difficulties, grants a concession to the debtor that it would not otherwise consider. The agencies confirmed with the staff of the Financial Accounting Standards Boards, or FASB, that short-term modifications made on a good faith basis in response to COVID-19 to borrowers who were current prior to any relief, are not to be considered TDRs. This includes short-term (e.g., six months) modifications such as payment deferrals, fee waivers, extensions of repayment terms, or other delays in payment that are insignificant. Borrowers considered current are those that are less than 30 days past due on their contractual payments at the time a modification program is implemented. This interagency guidance has not had a material impact on the Company’s financial statements for disclosure of the impact to date.

Emerging Growth Company

The Company qualifies as an “emerging growth company” under the Jumpstart Our Business Startups Act of 2012, or the JOBS Act, and may take advantage of certain exemptions from various reporting requirements that are applicable to public companies that are not emerging growth companies, including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved. In addition, even if the Company complies with the greater obligations of public companies that are not emerging growth companies, the Company may avail itself of the reduced requirements applicable to emerging growth companies from time to time in the future, so long as the Company is an emerging growth company. The Company will continue to be an emerging growth company until the earliest to occur of: (1) the end of the fiscal year following the fifth anniversary of the date of the first sale of common equity securities under the Company’s Registration Statement on Form S-1, which was declared effective by the SEC on September 12, 2019; (2) the last day of the fiscal year in which the Company has $1.07 billion or more in annual revenues; (3) the date on which the Company is deemed to be a “large accelerated filer” under the Securities Exchange Act of 1934, as amended, or the “Exchange Act”; or (4) the date on which the Company has, during the previous three-year period, issued publicly or privately, more than $1.0 billion in non-convertible debt securities.

Table of Contents

Section 107 of the JOBS Act provides that an emerging growth company can take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act of 1933 for complying with new or revised accounting standards. As an emerging growth company, the Company can delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. The Company elected to take advantage of the benefits of this extended transition period.

NOTE 2 Recent Accounting Pronouncements

The following FASB Accounting Standards Updates, or ASUs, are divided into pronouncements which have been adopted by the Company since January 1, 2020, and those which are not yet effective and have been evaluated or are currently being evaluated by management as of September 30, 2020.

Adopted Pronouncements

In January 2017, the FASB issued ASU No. 2017-04, Simplifying the Test for Goodwill Impairment. This ASU removes Step 2 of the goodwill impairment test, which requires a hypothetical purchase price allocation. Under the amended guidance, a goodwill impairment charge will now be recognized for the amount by which the carrying value of a reporting unit exceeds its estimated fair value, not to exceed the carrying amount of goodwill. For public business entities that are US Securities and Exchange Commission filers, ASU 2017-04, is effective for interim and annual reporting periods beginning after December 15, 2019. The Company adopted ASU 2017-04 effective January 1, 2020, and the new guidance did not have an impact on the Company’s consolidated financial statements.

In August 2018, the FASB issued ASU No. 2018-13, Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement. This ASU eliminates, adds, and modifies certain disclosure requirements for estimated fair value measurements. Among the changes, entities will no longer be required to disclose the amount of and reasons for transfers between Level 1 and Level 2 of the estimated fair value hierarchy, but will be required to disclose the range and weighted-average used to develop significant unobservable inputs for Level 3 estimated fair value measurements. ASU 2018-13 is effective for all entities interim and annual reporting periods beginning after December 15, 2019. The Company adopted ASU 2018-13 effective January 1, 2020, and the revised disclosure requirements did not have a material impact on the Company’s consolidated financial statements.

In August 2018, the FASB issued ASU 2018-15, Intangibles – Goodwill and Other – Internal Use Software (Subtopic 350-40) – Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract. ASU 2018-15 aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). The accounting for the service element of a hosting arrangement that is a service contract is not affected by these amendments. ASU 2018-15 was effective for the Company on January 1, 2020, and did not have an impact on the Company’s consolidated financial statements.

Pronouncements Not Yet Effective

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. This ASU requires a new impairment model known as the current expected credit loss, or CECL, which significantly changes the way impairment of financial instruments is recognized by requiring immediate recognition of estimated credit losses expected to occur over the remaining life of financial instruments. The main provisions of ASU 2016-13 include (1) replacing the “incurred cost” approach under GAAP with an “expected loss” model for instruments measured at amortized cost, (2) requiring entities to record an allowance for credit losses related to available-for-sale debt securities rather than a direct write-down of the carrying amount of the investments, as is required by the other-than-temporary impairment model under current GAAP, and (3) a simplified accounting model for purchase credit-impaired debt securities and loans. In November 2019, the FASB issued ASU No. 2019-10, Financial Instruments – Credit Losses (Topic 326). This update amends the effective date of ASU No. 2016-13 for certain entities, including private companies and smaller reporting companies, until fiscal years beginning after December 15, 2022, including interim periods within those fiscal periods. Early adoption is permitted.

Table of Contents

As an emerging growth company, the Company can take advantage of this delay and plans to adopt the standard with the amended effective date. The Company does not plan to early adopt this standard but continues to work on its implementation. The Company continues collecting and retaining loan and credit data and evaluating various loss estimation models. While we currently cannot reasonably estimate the impact of adopting this standard, we expect the impact will be influenced by the composition, characteristics, and quality of our loan portfolio, as well as the general economic conditions and forecasts as of the adoption date.

In April 2019, the FASB issued ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments—Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments, which affects a variety of topics in the Codification and applies to all reporting entities within the scope of the affected accounting guidance. The Company will consider these clarifications and improvements in determining the appropriate adoption of ASU 2019-04.

In May 2019, the FASB issued ASU 2019-05, Targeted Transition Relief to provide entities with an option to irrevocably elect the fair value option applied on an instrument-by-instrument basis for eligible instruments. In November 2019, the FASB Issued ASU 2019-10, which amends the effective date of this ASU for certain entities, including private companies and smaller reporting companies until after December 15, 2022, including interim periods within those fiscal years. As an emerging growth company, the Company can take advantage of this delay and plans to adopt the standard with the amended effective date. This update is not expected to have a significant impact on the Company’s consolidated financial statements.

In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740), which simplifies accounting for income taxes by removing certain exceptions to the general principles in Topic 740. The amendments also improve consistent application of and simplify GAAP for the areas of Topic 740 by clarifying and amending existing guidance. This guidance is effective for fiscal years, and interim periods within those fiscal years beginning after December 15, 2020, for public business entities. For private companies and smaller reporting companies, this guidance is effective for fiscal years, and interim periods within those fiscal years beginning after December 15, 2021. As an emerging growth company, the Company can take advantage of this later effective date. Early adoption of the amendments is permitted, including adoption in any interim period for which financial statements have not yet been issued. Depending on the amendment, adoption may be applied on the retrospective, modified retrospective, or prospective basis. The Company is currently reviewing the provisions of this new pronouncement, but does not expect adoption of this guidance to have a material impact on the Company’s consolidated financial statements.

In January 2020, the FASB issued ASU 2020-01, Investments – Equity Securities (Topic 321), Investments – Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815) – Clarifying the Interactions between Topic 321, Topic 323, and Topic 815. The ASU is based on a consensus of the Emerging Issues Task Force and is expected to increase comparability in accounting for these transactions. ASU 2016-01 made targeted improvements to accounting for financial instruments, including providing an entity the ability to measure certain equity securities without a readily determinable fair value at cost, less any impairment, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. Among other topics, the amendments clarify that an entity should consider observable transactions that require it to either apply or discontinue the equity method of accounting. For public business entities, the amendments in the ASU are effective for fiscal years beginning after December 15, 2020, and interim periods within those fiscal years. Early adoptions is permitted. The Company does not expect the adoption of ASU 2020-01 to have a material impact on its consolidated financial statements.

In March 2020, the FASB issued ASU 2020-03. Codification Improvements to Financial Instruments. This ASU represents changes to clarify or improve the Accounting Standards Codification, or ASC, related to seven topics. The amendments make the ASC easier to understand and easier to apply by eliminating inconsistencies and providing clarifications. Issues 1, 2, 3, 4, and 5 are conforming amendments and for public business entities effective upon the issuance of the standard. Issues 6 and 7 are amendments that affect the guidance in ASU 2016-13. The Company will consider these clarifications and improvements in determining the appropriate adoption of ASU 2016-13.

11

Table of Contents

In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. These amendments provide temporary optional guidance to ease the potential burden in accounting for reference rate reform. The ASU provides optional expedients and exceptions for applying GAAP to contract modifications and hedging relationships, subject to meeting certain criteria, that reference LIBOR or another reference rate expected to be discontinued. It is intended to help stakeholders during the global market-wide reference rate transition period. The guidance is effective for all entities as of March 12, 2020 through December 31, 2022. The Company is assessing ASU 2020-04 and its impact on the Company’s transition away from LIBOR for its loan and other financial instruments.

For all of the above investment securities, the unrealized losses were generally due to changes in interest rates and unrealized losses were considered to be temporary as the fair value is expected to recover as the securities approach their maturity dates. The Company evaluates securities for other-than-temporary impairment, or OTTI, on a quarterly basis, at a minimum, and more frequently when economic or market concerns warrant such evaluation. In estimating OTTI losses, consideration is given to the severity and duration of the impairment; the financial condition and near-term prospects of the issuer, which for debt securities, considers external credit ratings and recent downgrades; and the intent and ability of the Company to hold the security for a period of time sufficient for a recovery in value.

For the three and nine months ended September 30, 2020 and 2019, the Company did not recognize OTTI losses on its investment securities.

The following table presents amortized cost and estimated fair value of the available-for-sale investment securities as of September 30, 2020, by contractual maturity:

​

Expected maturities will differ from contractual maturities because issuers may have the right to call or prepay obligations with or without call or prepayment penalties.

Investment securities with a total carrying value of $115.4 million and $136.2 million were pledged as of September 30, 2020 and December 31, 2019, respectively, to secure public deposits and for other purposes required or permitted by law.

These securities can only be redeemed or sold at their par value and only to the respective issuing institution or to another member institution. The Company records these non-marketable equity securities as a component of other assets and periodically evaluates these securities for impairment. Management considers these non-marketable equity securities to be long-term investments. Accordingly, when evaluating these securities for impairment, management considers the ultimate recoverability of the par value rather than recognizing temporary declines in value.

Visa Class B Restricted Shares

In 2008, the Company received Visa Class B restricted shares as part of Visa’s initial public offering. These shares are transferable only under limited circumstances until they can be converted into the publicly traded Class A common shares. This conversion will not occur until the settlement of certain litigation which will be indemnified by Visa members, including the Company. Visa funded an escrow account from its initial public offering to settle these litigation claims. Should this escrow account be insufficient to cover these litigation claims, Visa is entitled to fund additional amounts to the escrow account by reducing each member bank’s Class B conversion ratio to unrestricted Class A shares. As of September 30, 2020, the conversion ratio was 1.6228. Based on the existing transfer restriction and the uncertainty of the outcome of the Visa litigation mentioned above, the 6,924 Class B shares (11,236 Class A equivalents) that the Company owned as of September 30, 2020 and December 31, 2019, are carried at a zero cost basis.

​

The Company’s consumer loan portfolio is primarily comprised of secured loans that are evaluated at origination on a centralized basis against standardized underwriting criteria. The Company generally does not risk rate consumer loans unless a default event such as bankruptcy or extended nonperformance takes place. Credit quality for the consumer loan portfolio is measured by delinquency rates, nonaccrual amounts and actual losses incurred.

The Company assigns a risk rating to all commercial loans, except pools of homogeneous loans, and periodically performs detailed internal and external reviews of risk rated loans over a certain threshold to identify credit risks and to assess the overall collectability of the portfolio. These risk ratings are also subject to examination by the Company’s regulators. During the internal reviews, management monitors and analyzes the financial condition of borrowers and guarantors, trends in the industries in which the borrowers operate and the estimated fair values of collateral securing the loans. These credit quality indicators are used to assign a risk rating to each individual loan.

The Company’s ratings are aligned to pass and criticized categories. The criticized category includes special mention, substandard, and doubtful risk ratings. The risk ratings are defined as follows:

Pass: A pass loan is a credit with no existing or known potential weaknesses deserving of management’s close attention.

Special Mention: Loans classified as special mention have a potential weakness that deserves management’s close attention. If left uncorrected, this potential weakness may result in deterioration of the repayment prospects for the loan or of the Company’s credit position at some future date. Special mention loans are not adversely classified and do not expose the Company to sufficient risk to warrant adverse classification.

Table of Contents

Substandard: Loans classified as substandard are not adequately protected by the current net worth and paying capacity of the borrower or of the collateral pledged, if any. Loans classified as substandard have a well-defined weakness or weaknesses that jeopardize the repayment of the debt. Well-defined weaknesses include a borrower’s lack of marketability, inadequate cash flow or collateral support, failure to complete construction on time, or the failure to fulfill economic expectations. They are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected.

Doubtful: Loans classified as doubtful have all the weaknesses inherent in those classified as substandard, with the added characteristic that the weaknesses make collection or repayment in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable.

Loss: Loans classified as loss are considered uncollectible and charged off immediately.

The adequacy of the allowance for loan losses is assessed at the end of each quarter. The allowance for loan losses includes a specific component related to loans that are individually evaluated for impairment and a general component related to loans that are segregated into homogeneous pools and collectively evaluated for impairment. The factors applied to these pools are an estimate of probable incurred losses based on management’s evaluation of historical net losses from loans with similar characteristics, which are adjusted by management to reflect current events, trends, and conditions. The adjustments include consideration of the following: changes in lending policies and procedures, economic conditions, nature and volume of the portfolio, experience of lending management, volume and severity of past due loans, quality of the loan review system, value of underlying collateral for collateral dependent loans, concentrations, and other external factors.

Loans with a carrying value of $1.2 billion as of September 30, 2020 and December 31, 2019, respectively, were pledged to secure public deposits, and for other purposes required or permitted by law.

Under certain circumstances, the Company will provide borrowers relief through loan restructurings. A restructuring of debt constitutes a TDR if the Company, for economic or legal reasons related to the borrower’s financial difficulties, grants a concession to the borrower that it would not otherwise consider. TDR concessions can include reduction of interest rates, extension of maturity dates, forgiveness of principal or interest due, or acceptance of other assets in full or partial satisfaction of the debt.

During the third quarter of 2020, there were no loans modified as a TDR. As of September 30, 2020, the Company had entered into modifications on 552 loans representing $151.4 million in principal balances, since the beginning of the pandemic. Of those loans, 27 loans with a total outstanding principal balance of $16.9 million, have been granted second deferral, 56 loans with a total outstanding principal balance of $12.0 million remain on the first deferral and the remaining loans have been returned to a normal payment status. These deferrals were generally no more than 90 days in duration and were not considered TDRs in accordance with the Interagency Statement on Loan Modifications and Reporting for Financial Institutions as issued on April 7, 2020. During the first quarter of 2019, there was one loan modified as a TDR as a result of extending the amortization period. As of December 31, 2019, the carrying value of the restructured loan was $0.2 million. The loan is currently performing according to the modified terms and there was no specific reserve for loan losses allocated to the loan modified as troubled debt restructuring.

The Company does not have material commitments to lend additional funds to borrowers with loans whose terms have been modified in troubled debt restructurings or whose loans are on nonaccrual.

NOTE 6 Loan Servicing

Loans serviced for others are not included in the accompanying consolidated balance sheets. The unpaid principal balances of loans serviced for others totaled $476.3 million and $541.9 million as of September 30, 2020 and December 31, 2019, respectively. Servicing loans for others generally consists of collecting mortgage payments, maintaining escrow accounts, disbursing payments to investors and collection and foreclosure processing. Loan servicing income is recorded on an accrual basis and includes servicing fees from investors and certain charges collected from borrowers, such as late payment fees, and is net of fair value adjustments to capitalized mortgage servicing rights.

Substantially all of the Company’s leases are classified as operating leases, and therefore, were previously not recognized on the Company’s consolidated financial statements. The Company has one existing finance lease for the Company’s headquarters building with a lease term through 2022.

The Company elected not to include short-term leases (i.e., leases with initial terms of twelve months or less), or equipment leases (deemed immaterial) on the consolidated financial statements. The following table presents the classification of the Company’s right-of-use, or ROU, assets and lease liabilities on the consolidated financial statements.

Finance lease liabilities |  | Long-term debt | ​ |  | 484 | ​ |  | 640
Total lease liabilities | ​ | ​ | ​ | $ | 9,155 | ​ | $ | 9,504

​

The calculated amount of the ROU assets and lease liabilities in the table above are impacted by the length of the lease term and the discount rate used to present value the minimum lease payments. The Company’s lease agreements often include one or more options to renew at the Company’s discretion. If at lease inception, the Company considers the exercising of a renewal option to be reasonably certain, the Company will include the extended term in the calculation of the ROU asset and lease liability. Regarding the discount rate, Topic 842 requires the use of the rate implicit in the lease whenever this rate is readily determinable. As this rate is rarely determinable, the Company utilizes its incremental borrowing rate at lease inception, on a collateralized basis, over a similar term. For operating leases existing prior to January 1, 2019, the rate for the remaining lease term as of January 1, 2019 was used. For the Company’s only finance lease, the Company utilized its incremental borrowing rate at lease inception.

NOTE 11 Financial Instruments with Off-Balance Sheet Risk

In the normal course of business, the Bank has outstanding commitment and contingent liabilities, such as commitments to extend credit and standby letters of credit, which are not included in the accompanying consolidated financial statements. The Bank’s exposure to credit loss in the event of nonperformance by the other party to the financial instruments for commitments to extend credit and standby letters of credit is represented by the contractual or notional amount of those instruments. The Bank uses the same credit policies in making such commitments as it does for instruments that are included in the statements of financial condition.

A summary of the contractual amounts of the Company’s exposure to off-balance sheet risk is as follows:

​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | September 30, | ​ | December 31,
(dollars in thousands) |  | 2020 |  | 2019
Commitments to extend credit | ​ | $ | 596,642 | ​ | $ | 586,365
Standby letters of credit | ​ |  | 7,073 | ​ |  | 8,516
Total | ​ | $ | 603,715 | ​ | $ | 594,881

​

Commitments to extend credit are agreements to lend to a client as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Company evaluates each client’s creditworthiness on a case by case basis. The amount of collateral obtained, if deemed necessary by the Company upon extension of credit, is based on management’s credit evaluation. Collateral held varies but may include accounts receivable, inventory, property and equipment, and income producing commercial properties.

The Company was not required to perform on any financial guarantees and did not incur any losses on its commitments during the past two years.

The Company utilizes standby letters of credit issued by either the Federal Home Loan Bank or the Bank of North Dakota to secure public unit deposits. The Company had a $150 thousand letter of credit with the Federal Home Loan Bank as of September 30, 2020 and December 31, 2019. With the Bank of North Dakota, the Company had $19.0 million of letters of credit outstanding as of September 30, 2020 and $20.0 million as of December 31, 2019. Bank of North Dakota letters of credit were collateralized by loans pledged to the Bank of North Dakota in the amount of $239.3 million and $242.0 million as of September 30, 2020 and December 31, 2019, respectively.

NOTE 12 Share-Based Compensation

The Company has granted equity awards pursuant to the Alerus Financial Corporation 2009 Stock Plan. The awards were in the form of restricted stock or restricted stock units and are considered to represent an element of employee compensation. Compensation expense for the awards is based on the fair value of Alerus Financial Corporation common stock at the time of grant. The value of awards that are expected to vest are amortized into expense over the vesting periods. The ability to grant awards under this plan has expired.

On May 6, 2019, the Company’s stockholders approved the Alerus Financial Corporation 2019 Equity Incentive Plan. This plan allows the compensation committee the ability to grant a wide variety of equity awards, including stock options, stock appreciation rights, restricted stock, restricted stock units and cash incentive awards in such forms and amounts as it deems appropriate to accomplish the goals of the plan. Any shares subject to an award that is cancelled, forfeited, or expires prior to exercise or realization, either in full or in part, shall again become available for issuance under the plan. However, shares subject to an award shall not again be made available for issuance or delivery under the plan if such shares are (a) tendered in payment of the exercise price of a stock option, (b) delivered to, or withheld by, the Company to satisfy any tax withholding obligation, or (c) covered by a stock-settled stock appreciation right or other awards that were not issued upon the settlement of the award. Shares vest, become exercisable and contain such other terms and conditions as determined by the compensation committee and set forth in individual agreements with the participant receiving the award. The plan authorizes the issuance of up to 1,100,000 shares of common stock. As of September 30, 2020, 28,242 stock awards and 49,604 restricted stock units had been issued under the plan.

Compensation expense relating to awards under these plans was $475 thousand and $335 thousand for the three months ended September 30, 2020 and 2019, respectively. Compensation expense relating to awards under these plans was $1.3 million and $1.2 million for the nine months ended September 30, 2020 and 2019, respectively.

The following table presents the activity in the stock plans for the nine months ended September 30, 2020 and 2019:

​

As of September 30, 2020, there was $3.2 million of unrecognized compensation expense related to non-vested awards granted under the plans. The expense is expected to be recognized over a weighted-average period of 3.47 years.

NOTE 14 Segment Reporting

The Company determines reportable segments based on the services offered, the significance of the services offered, the significance of those services to the Company’s financial statements, and management’s regular review of the operating results of those services. The Company operates through four operating segments: Banking, Retirement and Benefit Services, Wealth Management, and Mortgage.

The financial information presented for each segment includes net interest income, provision for loan losses, direct noninterest income, and direct noninterest expense, before indirect allocations. Corporate Administration includes the indirect overhead and is set forth in the table below. The segment net income before taxes represents direct revenue and expense before indirect allocations and income taxes.

The following table presents key metrics related to the Company’s segments for the periods presented:

NOTE 15 Earnings Per Share

Beginning in the third quarter of 2019, the Company elected to prospectively use the two-class method in calculating earnings per share due to the restricted stock awards and restricted stock units qualifying as participating securities. Under the two-class method, earnings available to common shareholders for the period are allocated between common shareholders and participating securities according to dividends declared (or accumulated) and participating rights in undistributed earnings. Average shares of common stock for diluted net income per common share include shares to be issued upon the vesting of restricted stock awards and restricted stock units granted under the Company's share-based compensation plans.

The calculation of basic and diluted earnings per share using the two-class method for the three and nine months ending September 30, 2020 and 2019 are presented below:

The Company has third party agreements that require a minimum dollar transfer amount upon a margin call. This requirement is dependent on certain specified credit measures. The amount of collateral posted with third parties at September 30, 2020 and December 31, 2019, respectively was $5.1 million and $853 thousand. The amount of collateral posted with third parties was deemed to be sufficient as of those dates to collateralize both the fair market value change as well as any additional amounts that may be required as a result of a change in the specified credit measures.

​

NOTE 17 Regulatory Matters

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

Quantitative measures established by regulation to ensure capital adequacy require the Company and the Bank to maintain minimum amounts and ratios (set forth in the following table) of common equity tier 1, tier 1, and total capital (as defined in the regulations) to risk weighted assets (as defined) and of tier 1 capital (as defined) to average assets (as defined). Management believes at September 30, 2020 and December 31, 2019, each of the Company and the Bank had met all of the capital adequacy requirements to which it was subject.

The following table presents the Company’s and the Bank’s actual capital amounts and ratios as of September 30, 2020 and December 31, 2019:

The Bank is subject to certain restrictions on the amount of dividends that it may pay without prior regulatory approval. The Company and the Bank are subject to the rules of the Basel III regulatory capital framework and related Dodd-Frank Wall Street Reform and Consumer Protection Act rules. The rules included the implementation of a 2.5 percent capital conservation buffer that is added to the minimum requirements for capital adequacy purposes. A banking organization with a conservation buffer of less than the required amount will be subject to the limitations on capital distributions, including dividend payments and certain discretionary bonus payments to executive officers. At September 30, 2020, the ratios for the Company and the Bank were sufficient to meet the conservation buffer. In addition, the Company must adhere to various U.S. Department of Housing and Urban Development, or HUD, regulatory guidelines including required minimum capital and liquidity to maintain their Federal Housing Administration approval status. Failure to comply with the HUD guidelines could result in withdrawal of this certification. As of September 30, 2020, and December 31, 2019, the Company was in compliance with HUD guidelines.

NOTE 18 Fair Value of Assets and Liabilities

The Company categorizes its assets and liabilities measured at estimated fair value into a three level hierarchy based on the priority of the inputs to the valuation technique used to determine estimated fair value. The estimated fair value hierarchy gives the highest priority to quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). If the inputs used in the determination of the estimated fair value measurement fall within different levels of the hierarchy, the categorization is based on the lowest level input that is significant to the estimated fair value measurement. Assets and liabilities valued at estimated fair value are categorized based on the following inputs to the valuation techniques as follows:

Level 1—Inputs that utilize quoted prices (unadjusted) in active markets for identical assets or liabilities that an entity has the ability to access.

Level 2—Inputs that include quoted prices for similar assets and liabilities in active markets and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument. Estimated fair values for these instruments are estimated using pricing models, quoted prices of investment securities with similar characteristics, or discounted cash flows.

Level 3—Inputs that are unobservable inputs for the asset or liability, which are typically based on an entity’s own assumptions, as there is little, if any, related market activity. Subsequent to initial recognition, the Company may re-measure the carrying value of assets and liabilities measured on a nonrecurring basis to estimated fair value. Adjustments to estimated fair value usually result when certain assets are impaired. Such assets are written down from their carrying amounts to their estimated fair value.

Table of Contents

Professional standards allow entities the irrevocable option to elect to measure certain financial instruments and other items at estimated fair value for the initial and subsequent measurement on an instrument-by-instrument basis. The Company adopted the policy to value certain financial instruments at estimated fair value. The Company has not elected to measure any existing financial instruments at estimated fair value; however, it may elect to measure newly acquired financial instruments at estimated fair value in the future.

Recurring Basis

The Company uses estimated fair value measurements to record estimated fair value adjustments to certain assets and liabilities and to determine estimated fair value disclosures.

The following tables present the balances of the assets and liabilities measured at estimated fair value on a recurring basis as of September 30, 2020 and December 31, 2019:

The following is a description of the valuation methodologies used for instruments measured at estimated fair value on a recurring basis, as well as the general classification of such instruments pursuant to the valuation hierarchy.

Investment Securities

When available, the Company uses quoted market prices to determine the estimated fair value of investment securities; such items are classified in Level 1 of the estimated fair value hierarchy. For the Company’s investment securities for which quoted prices are not available for identical investment securities in an active market, the Company determines estimated fair value utilizing vendors who apply matrix pricing for similar bonds for which no prices are observable or may compile prices from various sources. These models are primarily industry-standard models that

32

Table of Contents

consider various assumptions, including time value, yield curve, volatility factors, prepayment speeds, default rates, loss severity, current market, and contractual prices for the underlying financial instruments, as well as other relevant economic measures. Substantially all of these assumptions are observable in the marketplace, can be derived from observable data, or are supported by observable levels at which transactions are executed in the marketplace. Estimated fair values from these models are verified, where possible, against quoted prices for recent trading activity of assets with similar characteristics to the security being valued. Such methods are generally classified as Level 2. However, when prices from independent sources vary, cannot be obtained, or cannot be corroborated, a security is generally classified as Level 3.

Derivatives

All of the Company’s derivatives are traded in over-the-counter markets where quoted market prices are not readily available. For these derivatives, estimated fair value is measured using internally developed models that use primarily market observable inputs, such as yield curves and option volatilities, and accordingly, classify as Level 2. Examples of Level 2 derivatives are basic interest rate swaps and forward contracts.

Nonrecurring Basis

Certain assets are measured at estimated fair value on a nonrecurring basis. These assets are not measured at estimated fair value on an ongoing basis; however, they are subject to estimated fair value adjustments in certain circumstances, such as when there is evidence of impairment or a change in the amount of previously recognized impairment.

Net impairment related to nonrecurring estimated fair value measurements of certain assets as of September 30, 2020 and December 31, 2019 consisted of the following:

​

Loans Held for Sale

Loans originated and held for sale are carried at the lower of cost or estimated fair value. The Company obtains quotes or bids on these loans directly from purchasing financial institutions. Typically these quotes include a premium on the sale and thus these quotes indicate estimated fair value of the held for sale loans is greater than cost.

Impairment losses for loans held for sale that are carried at the lower of cost or estimated fair value, represent additional net write-downs during the period to record these loans at the lower of cost or estimated fair value, subsequent to their initial classification as loans held for sale.

Disclosure of estimated fair value information about financial instruments, for which it is practicable to estimate that value, is required whether or not recognized in the consolidated balance sheets. In cases in which quoted market prices are not available, estimated fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimate of future cash flows. In that regard, the derived estimated fair value estimates cannot be substantiated by comparison to independent markets and, in many cases could not be realized in immediate settlement of the instruments. Certain financial instruments, with an estimated fair value that is not practicable to estimate and all non-financial instruments, are excluded from the disclosure requirements. Accordingly, the aggregate estimated fair value amounts presented do not necessarily represent the underlying value of the Company.

The following disclosures represent financial instruments in which the ending balances, as of September 30, 2020 and December 31, 2019, were not carried at estimated fair value in their entirety on the consolidated balance sheets.

Cash and Cash Equivalents and Accrued Interest

The carrying amounts reported in the consolidated balance sheets approximate those assets and liabilities estimated fair values.

Loans

For variable-rate loans that reprice frequently and with no significant change in credit risk, estimated fair values are based on carrying values. The estimated fair values of other loans are estimated using discounted cash flow analysis, using interest rates currently being offered for loans with similar terms to borrowers of similar credit quality.

Bank-Owned Life Insurance

Bank-owned life insurance is carried at the amount due upon surrender of the policy, which is also the estimated fair value. This amount was provided by the insurance companies based on the terms of the underlying insurance contract.

Table of Contents

Deposits

The estimated fair values of demand deposits are, by definition, equal to the amount payable on demand at the consolidated balance sheet date. The estimated fair values of fixed-rate certificates of deposit are estimated using a discounted cash flow calculation that applies current incremental interest rates being offered on certificates of deposit to a schedule of aggregated expected monthly maturities of the outstanding certificates of deposit.

Short-Term Borrowings and Long-Term Debt

For variable-rate borrowings that reprice frequently, estimated fair values are based on carrying values. The estimated fair value of fixed-rate borrowings are estimated using discounted cash flow analysis, based on the Company’s current incremental borrowing rates for similar types of borrowing arrangements.

Off-Balance Sheet Credit-Related Commitments

Off-balance sheet credit related commitments are generally of short-term nature. The contract amount of such commitments approximates their estimated fair value since the commitments are comprised primarily of unfunded loan commitments which are generally priced at market at the time of funding.

The estimated fair values, and related carrying or notional amounts, of the Company’s financial instruments are as follows:

NOTE 19 COVID-19 Pandemic Response

On March 27, 2020, President Trump signed into Law the Coronavirus Aid Relief and Economic Security Act, or CARES Act, which established a $2.0 trillion economic stimulus package, including cash payments to individuals,

35

Table of Contents

supplemental unemployment insurance benefits and a $349 billion loan program administered through the U.S. Small Business Administration, or SBA, referred to as the PPP. Under the PPP, small businesses, sole proprietorships, independent contractors, and self-employed individuals were able to apply for loans from existing SBA lenders and other approved regulated lenders that enrolled in the program, subject to numerous limitations and eligibility criteria. The Bank participated as a lender in the PPP. In addition, the CARES Act provides financial institutions the option to temporarily suspend certain requirements under GAAP related to TDRs for a limited period of time to account for the effects of COVID-19. See “Note 4 Loans and Allowance for Loan Losses” for additional discussion regarding TDRs.

On April 2, 2020, the SBA issued an interim final rule, announcing the implementation of sections 1102 and 1106 of the CARES Act. Section 1102 of the CARES Act temporarily added a new program, the PPP, to the SBA’s 7(a) Loan Program. Section 1106 of the CARES Act provides for forgiveness of up to the full principal amount of qualifying loans guaranteed under the PPP. The PPP and loan forgiveness are intended to provide economic relief to small businesses nationwide adversely impacted by COVID-19.

As an SBA-Certified Preferred lender, we were delegated the authority as part of the CARES Act to make PPP SBA-guaranteed financing available to eligible borrowers. As of September 30, 2020, we had assisted 1,632 new and existing clients secure approximately $363.6 million of PPP financing. The SBA pays a processing fee based on the balance of the financing outstanding at the time of final disbursement. The processing fees were as follows: five percent for loans of not more than $350 thousand, three percent for loans of more than $350 thousand and less than $2 million, and one percent for loans of at least $2 million. Net processing fees in the amount of $11.0 million are being deferred and recognized as interest income on a level yield method over the life of the respective loans.

On April 7, 2020, the Board of Governors of the Federal Reserve System, or FRB, authorized each of the Federal Reserve Banks to establish the Payment Protection Program Lending Facility, or PPPL Facility, pursuant to section 13(3) of the Federal Reserve Act. Under the PPPL Facility, each of the Federal Reserve Banks will extend non-recourse loans to eligible financial institutions to fund loans guaranteed by the SBA under the PPP established by the CARES Act.

On April 15, 2020, we executed a PPPL Facility Agreement with the Federal Reserve Bank of Minneapolis. The PPP loans guaranteed by the SBA are eligible to serve as collateral for the PPPL Facility. The PPPL Facility provided us with additional liquidity, if necessary, to facilitate lending to small businesses under the PPP. As of September 30, 2020, we have not had a need to utilize the PPPL Facility.

Forward-looking statements are neither historical facts nor assurances of future performance.

Any forward-looking statement made by us in this report is based only on information currently available to us and speaks only as of the date on which it is made. We undertake no obligation to publicly update any forward-looking statement, whether written or oral, that may be made from time to time, whether as a result of new information, future developments or otherwise.

Overview

We are a diversified financial services company headquartered in Grand Forks, North Dakota. Through our subsidiary, Alerus Financial, National Association, or the Bank, we provide financial solutions to businesses and consumers through four distinct business lines—banking, retirement and benefit services, wealth management and mortgage. These solutions are delivered through a relationship-oriented primary point of contact along with responsive and client-friendly technology.

Our business model produces strong financial performance and a diversified revenue stream, which has helped us establish a brand and culture yielding both a loyal client base and passionate and dedicated employees. We generate a majority of our overall revenue from noninterest income, which is driven primarily by our retirement and benefit services, wealth management and mortgage business lines. The remainder of our revenue consists of net interest income, which we derive from offering our traditional banking products and services.

Critical Accounting Policies

Our consolidated financial statements are prepared based on the application of accounting policies generally accepted in the United States, or GAAP. The preparation of our consolidated financial statements requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses. These estimates are based upon historical experience and on various other assumptions that management believes are reasonable under current circumstances. These estimates form the basis for making judgments about the carrying value of certain assets and liabilities that are not readily available from other sources. Actual results may differ from these estimates under different assumptions or conditions. The estimates and judgments that management believes have the most effect on the Company’s reported financial position and results of operations are set forth in Note 1 – Significant Accounting Policies of the Notes to the Consolidated Statements, included in our Annual Report on Form 10-K for the year ended December 31, 2019. There have been no significant changes in critical accounting policies or the assumptions and judgments utilized in applying these policies since December 31, 2019.

The JOBS Act permits the Company an extended transition period for complying with new or revised accounting standards affecting public companies. The Company has elected to take advantage of this extended transition period, which means that the financial statements included in this report, as well as any financial statements filed in the future, will not be subject to all new or revised accounting standards generally applicable to public companies for the transition period for so long as the Company remains an emerging growth company or until the Company affirmatively and irrevocably opts out of the extended transition period under the JOBS Act.

Recent Developments

Impact of COVID-19

The progression of the COVID-19 pandemic in the United States has not had an adverse impact on our financial condition and results of operations as of and for the three and nine months ended September 30, 2020, but it is expected to have a complex and significant impact on the economy, the banking industry and our Company in future fiscal periods, all subject to a high degree of uncertainty.

Effects on Our Market Areas. Our primary banking market areas are the states of North Dakota, Minnesota, and Arizona. Our retirement and benefit services business serves clients in all 50 states. We offer retirement and benefit

39

Table of Contents

services at all of our banking offices located in our three primary market areas. In addition, we operate two retirement and benefits services offices in Minnesota, two in Michigan and one in New Hampshire.

In Minnesota, the Governor ordered individuals to stay at home and non-essential businesses to cease all activities, in each case subject to limited exceptions. This order went into effect on March 28, 2020, and was in effect until May 18, 2020. The state has now implemented a four phase stay safe plan to reopen businesses in the area. Similarly, in Arizona, the Governor ordered individuals to stay at home and non-essential businesses to cease all activities, in each case subject to limited exceptions. This order went into effect on March 31, 2020, and expired on May 15, 2020, and the Governor announced new guidance for protecting businesses and their customers as they reopen. The state has implemented a four phase reopening plan that requires benchmarks be met for a certain period of time before transitioning from one phase to another. In North Dakota, the Governor did not issue an order requiring individuals to stay at home, but placed certain restrictions on bars, restaurants and gyms. These orders have been lifted and North Dakota is now working toward a “Smart Restart” program to encourage businesses to open safely and take precautions to slow the spread of COVID-19. In response to these orders, the Bank has been serving its customers through its drive-up windows at various branch locations and through online and mobile banking. The Bank is also permitting certain visits to its branches on a limited basis and by appointment only. In Minnesota and Arizona, the Bank is offering appointments to our customers to meet us with safeguards in place that materially comply with CDC guidance. In North Dakota, certain offices have re-opened for business with safeguards in place that materially comply with CDC guidance.

Each state has experienced a dramatic and sudden increase in unemployment levels as a result of the curtailment of business activities. According to data released by the U.S. Department of Labor, initial claims for unemployment insurance have spiked in recent months in each of the states in our banking markets, a trend we expect to continue for the foreseeable future until restrictions are lifted. To date, many of the public health and economic effects of COVID-19 have been concentrated in the largest U.S. cities, such as New York, but we are beginning to see similar effects in smaller cities and communities, where many of our banking operations are focused.

Policy and Regulatory Developments. Federal, state and local governments and regulatory authorities have enacted and issued a range of policy responses to the COVID-19 pandemic, including the following:

| ● | The Federal Reserve decreased the range for the Federal Funds Target Rate by 0.50% on March 3, 2020, and by another 1.00% on March 16, 2020, reaching a current range of 0.00 – 0.25%.

| ● | On March 27, 2020, President Trump signed into law the Coronavirus Aid, Relief and Economic Security Act, or CARES Act, which established a $2.0 trillion economic stimulus package, including cash payments to individuals, supplemental unemployment insurance benefits and a $349 billion loan program administered through the U.S. Small Business Administration, or SBA, referred to as the paycheck protection program, or PPP. On April 24, 2020, an additional $310 billion in funding for PPP loans was authorized, with such funds available for PPP loans beginning on April 27, 2020. In addition, the CARES Act provides financial institutions the option to temporarily suspend certain requirements under GAAP related to TDRs for a limited period of time to account for the effects of COVID-19. See “NOTE 4 Loans and Allowance for Loan Losses” for additional discussion regarding TDRs.

| ● | On April 7, 2020, federal banking regulators issued a revised Interagency Statement on Loan Modifications and Reporting for Financial Institutions, which, among other things, encouraged financial institutions to work prudently with borrowers who are or may be unable to meet their contractual payment obligations because of the effects of COVID-19, and stated that institutions generally do not need to categorize COVID-19-related modifications as TDRs and that the agencies will not direct supervised institutions to automatically categorize all COVID-19 related loan modifications as TDRs. See “NOTE 4 Loans and Allowance for Loan Losses” for additional discussion regarding TDRs.

| ● | On April 9, 2020, the Federal Reserve announced additional measures aimed at supporting small and midsized business, as well as state and local governments impacted by COVID-19. The Federal Reserve announced the Main Street Business Lending Program, which established two new loan facilities intended to facilitate lending to small and midsized businesses: (1) the Main Street New Loan Facility, or MSNLF,

40

Table of Contents

|  | and (2) the Main Street Expanded Loan Facility, or MSELF. MSNLF loans are unsecured term loans originated on or after April 8, 2020, while MSELF loans are provided as upsized tranches of existing loans originated before April 8, 2020. The combined size of the program is $600 billion.

| ● | On August 3, 2020, the FFIEC issued a joint statement on Additional Loan Accommodations Related to COVID-19, which, among other things, encouraged financial institutions to consider prudent additional loan accommodation options when borrowers are unable to meet their obligations due to continuing financial challenges. Accommodation options should be based on prudent risk management and consumer protection principles.

| ● | In addition to the policy responses described above, the federal bank regulatory agencies, along with their state counterparts, have issued a stream of guidance in response to the COVID-19 pandemic and have taken a number of unprecedented steps to help banks navigate the pandemic and mitigate its impact. These include, without limitation: requiring banks to focus on business continuity and pandemic planning; adding pandemic scenarios to stress testing; encouraging bank use of capital buffers and reserves in lending programs; permitting certain regulatory reporting extensions; reducing margin requirements on swaps; permitting certain otherwise prohibited investments in investment funds; issuing guidance to encourage banks to work with customers affected by the pandemic and encourage loan workouts; and providing credit under the Community Reinvestment Act, or CRA, for certain pandemic-related loans, investments and public service. Moreover, because of the need for social distancing measures, the agencies have revamped the manner in which they conduct periodic examinations of their regulated institutions, including making greater use of off-site reviews. The Federal Reserve also issued guidance encouraging banking institutions to utilize their discount window for loans and intraday credit extended by their Reserve Banks to help households and businesses impacted by the pandemic and announced numerous funding facilities. The FDIC has also acted to mitigate the deposit insurance assessment effects of participating in the PPP and the PPPL Facility and Money Market Mutual Fund Liquidity Facility.

Effects on Our Business. We currently expect that the COVID-19 pandemic and the specific developments referred to above will continue to have a significant impact on our business. In particular, we anticipate that a significant portion of the Bank’s borrowers in the retail, restaurant, and hospitality industries will continue to endure significant economic distress, which could cause them to draw on their existing lines of credit and could adversely affect their ability and willingness to repay existing indebtedness, and is expected to adversely impact the value of collateral. These developments, together with economic conditions generally, are also expected to impact our commercial real estate portfolio, particularly with respect to real estate with exposure to these industries, our consumer loan business and loan portfolio, and the value of certain collateral securing our loans. In addition, we expect to see decreases in our total assets under administration and assets under management and a decrease in mortgage loan originations. As a result, we anticipate that our financial condition, capital levels and results of operations will be significantly and adversely affected, as described in this Management’s Discussion and Analysis of Financial Condition and Results of Operations.

Our Response. We have taken numerous steps in response to the COVID-19 pandemic, including the following:

| ● | First and foremost, we have prioritized the safety, health and well-being of our employees, clients and communities. We have implemented a work from home policy and certain of our offices remain closed. We continue to effectively serve our clients in all markets; virtually, digitally, via drive-thru and in-person as conditions allow. Our work place strategy includes various phases of expanding service to clients, reopening offices, and determining long-term work arrangements for employees. This approach allows us to incrementally expand in-person services to clients and provides flexibility between markets based on local conditions, guidelines, and restrictions.

| ● | We offered payment deferrals and interest only payment options for consumer, small business, and commercial customers for initial terms of up to 90 days. We offered payment extensions for mortgage customers for initial terms of up to 90 days. As of September 30, 2020, we had executed 552 loan deferrals representing $151.4 million. Of those loans, 27 loans with a total outstanding principal balance of $16.9

41

Table of Contents

|  | million have been granted second deferrals, 56 loans with a total outstanding principal balance of $12.0 million remain on the first deferral and the remaining loans have been returned to a normal payment status.

| ● | The Business Continuity Planning COVID-19 Response team and Alerus leadership teams meet regularly to manage the Company’s response to the pandemic and the effect on our business. In addition, a cross functional task force team meets regularly to address specific issues such as employee and client communications, facilities, reopening offices, and long-term work arrangements. The Risk Committee of the Board meets regularly with management to receive updates on the Company’s response and discuss the effect on our business.

| ● | We participated in the SBA’s PPP. As of September 30, 2020, we had assisted 1,632 borrowers receive approval for funding of $363.6 million in PPP loans. As of October 22, 2020, we had submitted to the SBA 79 forgiveness applications totaling $51.7 million. We have not yet received any decisions from the SBA on the applications submitted, and no forgiveness has been granted as of that date.

| ● | In addition, as disclosed in our Annual Report on Form 10-K for the year ended December 31, 2019, we will not be permitted to make capital distributions (including dividends and repurchases of stock) or pay discretionary bonuses to executive officers without restriction if we do not maintain 2.5% in Common Equity Tier 1 Capital attributable to a capital conservation buffer.

Shareholder Dividend and Stock Repurchases

On July 23, 2020, the Company’s Board of Directors declared a quarterly cash dividend of $0.15 per common share. This dividend was paid out on October 9, 2020, to stockholders of record at the close of business on September 18, 2020.

Although the Board of Directors is closely monitoring the impacts of the COVID-19 pandemic, it is the current expectation and intent of the Board of Directors to continue with a quarterly cash dividend.

We currently do not have an authorized stock repurchase program, but the Company does repurchase shares to pay withholding taxes on the vesting of restricted stock awards and units.

Non-GAAP to GAAP Reconciliations and Calculation of Non-GAAP Financial Measures

In addition to the results presented in accordance with GAAP, we routinely supplement our evaluation with an analysis of certain non-GAAP financial measures. These non-GAAP financial measures include the ratio of tangible common equity to tangible assets, tangible book value per common share, return on average tangible common equity, net interest margin (tax-equivalent), and the efficiency ratio. Management uses these non-GAAP financial measures in its analysis of its performance, and believes financial analysts and others frequently use these measures, and other similar measures, to evaluate capital adequacy. Management calculates: (i) tangible common equity as total common stockholders' equity less goodwill and other intangible assets; (ii) tangible common equity per share as tangible common equity divided by shares of common stock outstanding; (iii) tangible assets as total assets, less goodwill and other intangible assets; (iv) return on average tangible common equity as net income adjusted for intangible amortization net of tax, divided by average tangible common equity; (v) net interest margin (tax-equivalent) as net interest income plus a tax-equivalent adjustment, divided by average earning assets; and (vi) efficiency ratio as noninterest expense less intangible amortization expense, divided by net interest income plus noninterest income plus a tax-equivalent adjustment.

Discussion and Analysis of Results of Operations

Net Income

Net income for the three months ended September 30, 2020 was $17.7 million, or $0.99 per diluted common share, a $10.6 million increase as compared to $7.1 million, or $0.48 per diluted common share, for the three months ended September 30, 2019. This increase in net income was primarily due to a $15.7 million increase in noninterest income and a $3.1 million increase in net interest income, partially offset by increases of $2.9 million in noninterest expense, $2.0 million in provision expense, and $3.3 million in income tax expense. The increase in noninterest income was primarily due to a $14.1 million increase in mortgage banking revenue due to an increase in mortgage originations. The increase in noninterest expense was primarily attributable to an increase in compensation expense related to the increase in mortgage originations.

Net income for the nine months ended September 30, 2020 was $34.5 million, or $1.94 per diluted common share, compared to $21.9 million, or $1.49 per diluted common share, for the nine months ended September 30, 2019. The increase of $12.6 million was due to increases of $26.0 million in noninterest income and $4.6 million in net interest income, partially offset by increases of $10.6 million in noninterest expense and $3.5 million in income tax expense. The increase in noninterest income was primarily due to a $25.1 million increase in mortgage banking revenue as a result of a $486.6 million increase in mortgage originations. The increase in noninterest expense was primarily attributable to an increase in compensation expense related to the increase in mortgage originations.

Net Interest Income

Net interest income is the difference between interest income and yield-related fees earned on assets and interest expense paid on liabilities. Net interest margin is the difference between the yield on interest earning assets and the cost of interest-bearing liabilities as a percentage of interest earning assets. Net interest margin is presented on a tax-equivalent basis, which means that tax-free interest income has been adjusted to a pre-tax-equivalent income, assuming a federal income tax rate of 21% for the three and nine months ended September 30, 2020 and 2019.

In response to the COVID-19 pandemic, the Federal Reserve decreased the targeted federal funds rate by a total of 150 basis points in March 2020. This decrease impacts the comparability of net interest income between 2019 and 2020. We anticipate that our interest income will be significantly and adversely affected in future periods as a result of the COVID-19 pandemic, including as a result of the effects of lower interest rates.

Net interest income for the three months ended September 30, 2020 was $21.8 million, an increase of $3.1 million from $18.7 million for the three months ended September 30, 2019. The three months ended September 30, 2020 included a $2.4 million decrease in interest expense compared to the same period in 2019 and a $664 thousand increase in interest income. The decrease in interest expense was primarily driven by a decrease of $1.8 million in deposit interest expense and a decrease of $539 thousand in interest expense on short-term borrowings. The decrease in deposit interest expense for the three months ended September 30, 2020, compared to the same period 2019 was driven primarily by a 72 basis point reduction in the average rate paid on interest-bearing deposits, partially offset by a $495.2 million increase in the average balance of interest-bearing deposits. The decrease in interest expense on short-term borrowings for the three months ended September 30, 2020, was primarily due to an $87.2 million decrease in the average balance in short-term borrowings. The increase in interest income was primarily driven by a $674 thousand increase in interest income from investment securities as a result of a $186.1 million increase in the average balance of investment securities.

Net interest income for the nine months ended September 30, 2020 was $60.7 million, an increase of $4.6 million from $56.1 million for the nine months ended September 30, 2019. The increase in net interest income was primarily driven by a decrease of $4.1 million in interest expense as well as a $488 thousand increase in interest income. The decrease in interest expense was driven by a $2.2 million decrease in deposit interest expense. The increase in interest income was primarily driven by a $1.6 million increase in interest income from investment securities, partially offset by a $1.3 million decrease in interest and fees on loans. The decrease in interest expense on deposits was due to a 39 basis point reduction in the average rate paid on interest-bearing deposits, partially offset by a $336.0 million increase in the average balance of interest-bearing deposits. The increase in interest income from investment securities was

Table of Contents

primarily due to a $127.7 increase in the average balance of investment securities. The decrease in interest and fees on loans was primarily driven by a 66 basis point decrease in the average yield on total loans.

Our net interest margin (on a fully tax-equivalent, or FTE, basis) for the three months ended September 30, 2020 was 3.17%, compared to 3.69% for the same period in 2019. The decrease in net interest margin from the third quarter of 2019 was due to a 112 basis point lower average earning asset yield, partially offset by an 84 basis point decrease in the average rate paid on interest-bearing liabilities. The decrease in the average earning asset yield was primarily due to an 86 basis point decrease in the average yield on total loans. The decline in loan yield was primarily due to the addition of PPP loan balances which averaged $348.1 million during the quarter with a yield of 3.64%. The decrease in the average rate paid on total interest-bearing liabilities was primarily due to a 100 basis point decrease in the average rate paid on money market and savings deposits.

Our net interest margin (FTE) for the nine months ended September 30, 2020 was 3.22%, compared to 3.72% for the same period in 2019. The decrease in net interest margin was primarily attributable to a 92 basis point decrease on the average earning asset yield, partially offset by a 52 basis point decrease in the average rate on interest-bearing liabilities. The decrease in the average earning asset yield was primarily due to a 66 basis point reduction in the average yield on total loans. The decline in loan yield was primarily due to PPP loan balances which averaged $207.8 million for the nine months ended September 30, 2020 with a yield of 3.37%.The decrease in average rate on interest-bearing liabilities was the result of a 57 basis point decrease in the average rate on money market and savings deposits and a $95.4 million decrease in the average balance on short-term borrowings.

As a result of the recent reductions in the target federal funds interest rate, as well as the impact of the COVID-19 pandemic and related future loan charge-offs that we expect to incur, we anticipate that our net interest income and net interest margin FTE will decrease in future periods. These decreases will be partially offset by the processing fees received from PPP financing, which fees are being deferred and recognized as an adjustment to interest income over the life of the loans.

Table of Contents

The following tables present average balance sheet information, interest income, interest expense and the corresponding average yields on assets, and average yields earned and rates paid for the three and nine months ended September 30, 2020 and 2019. We derived these yields and rates by dividing income or expense by the average balance of the corresponding assets or liabilities. We derived average balances from the daily balances throughout the periods indicated. Average loan balances include loans that have been placed on nonaccrual, while interest previously accrued on these loans is reversed against interest income. In these tables, adjustments are made to the yields on tax-exempt assets in order to present tax-exempt income and fully taxable income on a comparable basis.

Interest Rates and Operating Interest Differential

Increases and decreases in interest income and interest expense result from changes in average balances (volume) of interest earning assets and interest-bearing liabilities, as well as changes in average interest rates. The following table shows the effect that these factors had on the interest earned on our interest earning assets and the interest incurred on our interest-bearing liabilities. The effect of changes in volume is determined by multiplying the

Provision for Loan Losses

The provision for loan losses is based upon our allowance methodology and is a charge to income that, in our judgment, is required to maintain an adequate allowance for incurred loan losses at each period-end. In assessing the adequacy of the allowance, management considers the size and quality of the loan portfolio measured against prevailing economic conditions, regulatory guidelines, and historical loan loss experience. However, there is no assurance that loan credit losses will not exceed the allowance, and any growth in the loan portfolio and the uncertainty of the general economy may require additional provisions in future periods.

We recorded a provision for loan losses of $3.5 million for the three months ended September 30, 2020, a $2.0 million increase compared to the $1.5 recorded for the three months ended September 30, 2019. The increase in provision expense was primarily due to allocations of reserves for the economic uncertainties related to COVID-19. We expect the provision for loan losses could increase in future periods based on our belief that the credit quality of our loan portfolio may decline, and loan defaults may increase, as a result of COVID-19.

We recorded a provision for loan losses of $9.5 million for the nine months ended September 30, 2020, a $4.0 million increase compared to the $5.5 million for the nine months ended September 30, 2019. The increase in provision expense was primarily due to allocations of reserves for the economic uncertainties related to COVID-19.

Noninterest Income

Our noninterest income is generated from four primary sources: (1) retirement and benefit services; (2) wealth management; (3) mortgage banking; and (4) other general banking services.

The following table presents our noninterest income for the three and nine months ended September 30, 2020 and 2019.

​

Total noninterest income for the three months ended September 30, 2020 was $45.3 million, an increase of $15.7 million, or 53.0%, compared to $29.6 million for the three months ended September 30, 2019. The increase in noninterest income was primarily due to an increase of $14.1 million in mortgage banking revenue, a $1.4 million increase in net gains and losses on investment securities, and a $590 thousand increase in wealth management revenue, partially offset by a $203 thousand decrease in retirement and benefit services revenue. Mortgage banking revenue increased primarily due to a $198.1 million increase in mortgage originations along with a 75 basis point increase in the gain on sale margin. Wealth management revenue increased as a result of an increase in the average balance of assets under administration/management. The decrease in retirement and benefit services revenue was primarily due to a $347 thousand decrease in asset based fees.

Total noninterest income for the nine months ended September 30, 2020 was $110.7 million, an increase of $26.0 million or 30.8%, compared to $84.6 million for the nine months ended September 30, 2019. The increase in noninterest income was primarily driven by an increase of $25.1 million in mortgage banking revenue and a $2.4 million increase in net gains and losses on investment securities, partially offset by a $1.4 million decrease in other noninterest income. Mortgage banking revenue increased as mortgage originations increased from $685.2 million for the nine months ended September 30, 2019 to $1.17 billion for the nine months ended September 30, 2020, along with a 35 basis point increase in the gain on sale margin. Other noninterest income decreased $1.4 million for the nine months ended September 30 of 2020 due to a $1.5 million gain on the sale of a branch that occurred in 2019.

We anticipate that our noninterest income will be significantly adversely affected in future periods as a result of the COVID-19 pandemic and the related decline in global economic conditions and significant volatility in the global stock markets. We expect retirement and benefit services asset based revenue will be adversely affected by reduced assets under administration and assets under management, waived transaction and participant related fees, and a decline in ESOP transaction fees. We expect wealth management asset based revenue will be adversely affected by reduced assets under administration and assets under management and we also expect increased unemployment and recessionary concerns will adversely affect mortgage originations and mortgage banking revenue in future periods.

Noninterest income as a percentage of total operating revenue, which consists of net interest income plus noninterest income, was 67.5% for the three months ended September 30, 2020, compared to 61.3% for the three months ended September 30, 2019. The increase was due to noninterest income increasing by 53.0% while net interest income increased by only 16.5%.

Noninterest income as a percentage of total operating revenue was 64.6% for the nine months ended September 30, 2020, compared to 60.1% for the nine months ended September 30, 2019. The increase was due to noninterest income increasing by 30.8% while net interest income increased by only 8.2%.

​

Total noninterest expense for the three months ended September 30, 2020 was $40.2 million, an increase of $2.9 million, or 7.7%, compared to $37.3 million for the three months ended September 30, 2019. The increase in noninterest expense was driven by increases of $2.7 million in compensation expense, $480 thousand in mortgage and lending expenses, $433 thousand in employee taxes and benefits, and $196 thousand in business services, software and technology expense, partially offset by a $409 thousand decrease in travel and a $384 thousand decrease in supplies and postage. Increases in compensation, employee taxes and benefits and mortgage and lending expenses were a direct result of increases in mortgage originations. The increase in business services, software and technology expenses was a result of an increase in information technology service expenses related to our “One Alerus” initiative and additional equipment purchases. The decrease in travel was a direct result of COVID-19 and the decrease in supplies and postage was due to a transition to E-statements for our retirement and benefit services segment.

Total noninterest expense for the nine months ended September 30, 2020 was $116.7 million, an increase of $10.6 million, or 10.0%, compared to $106.1 million for the nine months ended September 30, 2019. The increase in noninterest expense was due to increases of $7.7 million in compensation expense, $1.5 million in mortgage and lending expense, $1.3 in business services, software and technology expense, and $1.2 million in other noninterest expense, partially offset by decreases of $1.0 million in travel and $402 thousand in supplies and postage. The increases in compensation and mortgage and lending expenses were a result of increased mortgage originations. The increase in business services, software and technology expense was due to our continued investment in software and technology related to our “One Alerus” initiative. The increase in other noninterest expense was primarily due to a $1.2 million increase in the provision for unfunded commitments. The decrease in travel was a direct result of COVID-19 and the decrease in supplies and postage was due to a transition to E-statements for our retirement and benefit services segment.

Income Tax Expense

Income tax expense is an estimate based on the amount we expect to owe the respective taxing authorities, plus the impact of deferred tax items. Accrued taxes represent the net estimated amount due, or to be received from, taxing authorities. In estimating accrued taxes, management assesses the relative merits and risks of the appropriate tax treatment of transactions, taking into account statutory, judicial, and regulatory guidance in the context of our tax position. If the final resolution of taxes payable differs from our estimates due to regulatory determination or legislative or judicial actions, adjustments to tax expense may be required.

Table of Contents

For the three months ended September 30, 2020, we recognized income tax expense of $5.6 million on $23.3 million of pre-tax income, resulting in an effective tax rate of 24.2%, compared to income tax expense of $2.3 million on $9.4 million of pre-tax income for the three months ended September 30, 2019, resulting in an effective tax rate of 24.7%.

For the nine months ended September 30, 2020, we recognized income tax expense of $10.7 million on $45.2 million of pre-tax income, resulting in an effective tax rate of 23.7%, compared to income tax expense of $7.2 million on $29.1 million of pre-tax income for the nine months ended September, 2019, resulting in an effective tax rate of 24.8%. The decrease in the effective tax rate was primarily due to additional tax benefits from share-based compensation for the nine months ended September 30, 2020, as compared to the same period in 2019.

Financial Condition

Overview

Total assets were $2.9 billion as of September 30, 2020, an increase of $541.9 million, or 23.0%, as compared to December 31, 2019. The increase in total assets was primarily due to increases of $337.1 million in loans, $185.1 million in available-for-sale investments, $64.5 million in loans held for sale, and $15.3 million in other assets.

Loans

The loan portfolio represents a broad range of borrowers comprised of commercial and industrial, commercial real estate, residential real estate, and consumer financing loans. The goal of the overall portfolio mix is to diversify with approximately one third of the portfolio in each of the commercial and industrial, commercial real estate, and residential real estate categories. As of September 30, 2020, the portfolio mix was 38.3% commercial and industrial, 26.0% commercial real estate, 30.2% residential real estate and 5.5% in other categories. Commercial and industrial loans included $348.9 million of PPP loans as of September 30, 2020.

The following table presents the composition of total loans outstanding by portfolio segment as of September 30, 2020 and December 31, 2019:

​

Total loans outstanding were $2.06 billion as of September 30, 2020, an increase of $337.1 million, or 19.6%, from December 31, 2019. The increase was primarily due to increases of $309.9 million in commercial and industrial loans and $40.5 million in our commercial real estate loan portfolio, partially offset by a $20.1 million decrease in our consumer loan portfolio. The increase in commercial and industrial loans was due to an increase of $348.9 million in net PPP loans, offset by a decrease of $64.6 million, or 7.64% in operating line utilization.

Consistent with regulatory guidance urging banks to work with borrowers during this unprecedented situation and as outlined in the CARES Act, the Company offered a payment deferral program for its lending clients that are adversely affected by COVID-19. These deferrals were generally no more than 90 days in duration. As of September 30, 2020, the Company had executed 552 of these deferrals representing $151.4 million. Of those loans, 27 loans with a total outstanding principal balance of $16.9 million have been granted second deferrals, 56 loans with a total outstanding principal balance of $12.0 million remain on the first deferral and the remaining loans have been returned to a normal payment status. In accordance with the Interagency Statement on Loan Modifications and Reporting for Financial institutions as issued on April 7, 2020, these short-term deferrals were not considered TDRs. See “NOTE 4 Loans and Allowance for Loan Losses” to the consolidated financial statements for additional information regarding TDRs.

We anticipate that loan growth will slow down in the future for our commercial and industrial, commercial real estate, residential real estate, and consumer loan portfolios as a result of COVID-19 and the related decline in economic conditions in our market areas.

The following table presents the maturities and types of interest rates for the loan portfolio as of September 30, 2020.

​

As of September 30, 2020, 62.1% of the loan portfolio bore interest at fixed rates and 37.9% at floating rates. The expected life of our loan portfolio will differ from contractual maturities because borrowers may have the right to curtail or prepay their loans with or without penalties. Consequently, the table above includes information limited to contractual maturities of the underlying loans.

Asset Quality

Our strategy for credit risk management includes well-defined, centralized credit policies; uniform underwriting criteria; and ongoing risk monitoring and review processes for all commercial and consumer credit exposures. The strategy also emphasizes diversification on a geographic, industry, and client level; regular credit examinations; and management reviews of loans experiencing deterioration of credit quality. We strive to identify potential problem loans early, take necessary charge-offs promptly, and maintain adequate reserve levels for probable loan losses inherent in the portfolio. Management performs ongoing, internal reviews of any problem credits and continually assesses the adequacy of the allowance. We utilize an internal lending division, Special Credit Services, to develop and implement strategies for the management of individual nonperforming loans.

Credit Quality Indicators

Loans are assigned a risk rating and grouped into categories based on relevant information about the ability of borrowers to service their debt such as: current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. The risk ratings are aligned to pass and criticized categories. The criticized categories include special mention, substandard, and doubtful risk ratings. See “NOTE 4 Loans and Allowance for Loan Losses” to the consolidated financial statements for a definition of each of the risk ratings.

Allowance for Loan Losses

The allowance for loan losses represents management’s estimate of incurred credit losses inherent in the loan portfolio at the balance sheet date. The allowance for loan losses is maintained at a level management believes is sufficient to absorb incurred losses in the loan portfolio given the conditions at the time. Management determines the adequacy of the allowance based on periodic evaluations of the loan portfolio, after consideration of risk characteristics of the loans and prevailing and anticipated economic and other conditions. A risk system, consisting of multiple grading categories for each portfolio class, is utilized as an analytical tool to assess risk and appropriate reserves. In addition to the risk system, management further evaluates risk characteristics of the loan portfolio under current and anticipated economic conditions and considers such factors as the financial condition of the borrower, past and expected loss experience, and other factors which management feels deserve recognition in establishing an appropriate reserve. These estimates are reviewed at least quarterly, and, as adjustments become necessary, they are recognized in the periods in which they become known. These evaluations are inherently subjective as they require management to make material estimates, all of which may be susceptible to significant change.

The allowance for loan losses was $31.3 million as of September 30, 2020, compared to $23.9 million as of December 31, 2019. The $7.4 million increase in the allowance for loan losses was due to additional provision for loan losses of $9.5 million, partially offset by net charge-offs of $2.1 million. The increase in provision expense was primarily due to allocations of reserves for the economic uncertainties related to COVID-19. As of September 30, 2020, the allowance for loan losses represented 1.52% of total loans. Excluding PPP loans, the ratio of allowance for loan losses to total loans increased 44 basis points to 1.83% at September 30, 2020, compared to 1.39% as of December 31, 2019. For the nine months ended September 30, 2020, the ratio of net charge-offs to average total loans was 0.15%.

Based on current economic indicators, the Company increased the economic factors within the allowance for loan losses evaluation. We expect that the allowance for loan losses as a percent of total loans may increase in future periods based on our belief that the credit quality of our loan portfolio may decline, and loan defaults may increase, as a result of COVID-19.

The following table presents the allocation of the allowance for loan losses as of the dates presented.

​

In the ordinary course of business, we enter into commitments to extend credit, including commitments under credit arrangements, commercial letters of credit, and standby letters of credit. Such financial instruments are recorded when they are funded. A reserve for unfunded commitments is established using historical loss data and utilization assumptions. This reserve is located in accrued expenses and other liabilities on the Consolidated Balance Sheets. The reserve for unfunded commitments was $1.9 million as of September 30, 2020, an increase of $800 thousand, as compared to December 31, 2019.

Loans Held for Sale

Loans held for sale represent loans to consumers for the purchase or refinance of a residence that we have originated and intend to sell into the secondary market. Loans held for sale were $111.3 million as of September 30, 2020, an increase of $64.5 million, as compared to December 31, 2019. The increase in loans held for sale was primarily due to increased mortgage originations through September and investor pipeline capacity. Mortgage loan originations totaled $511.6 million for the three months ended September 30, 2020 compared to $261.3 million for the three months ended December 31, 2019.

Investment Securities

The composition of our investment securities portfolio reflects our investment strategy of maintaining an appropriate level of liquidity for normal operations while providing an additional source of revenue. The investment portfolio also provides a balance to interest rate risk and credit risk in other categories of the balance sheet, while providing a vehicle for the investment of available funds, furnishing liquidity, and supplying securities to pledge as collateral.

Deposits

Total deposits were $2.46 billion as of September 30, 2020, an increase of $491.1 million, or 24.9%, as compared to December 31, 2019. Interest-bearing deposits increased $375.3 million while noninterest-bearing deposits increased $115.7 million. The increase in deposits was primarily due to higher customer balances resulting from PPP loans, government stimulus, and the uncertain economic environment. The increase in interest-bearing deposits included a $128.8 million increase in synergistic deposits from our retirement and benefit services and wealth management segments. In addition, health savings account, or HSA, deposits were $131.5 million as of September 30, 2020, an increase of $11.8 million, or 9.9%, from December 31, 2019. Noninterest-bearing deposits as a percent of total deposits was 28.2% and 29.3% as of September 30, 2020 and December 31, 2019, respectively. Total deposits represented 95.6% of total liabilities as of September 30, 2020.

We expect that deposit levels will generally decrease in future periods as a result of the distressed economic conditions in our market areas as a result of the COVID-19 pandemic and as clients continue to utilize funds received from PPP loans.

Capital Resources

Stockholders' equity is influenced primarily by earnings, dividends, the Company's sales and repurchases of its common stock and changes in accumulated other comprehensive income caused primarily by fluctuations in unrealized gains or losses, net of taxes, on available-for-sale securities.

Stockholders' equity increased $36.3 million to $322.0 million as of September 30, 2020, compared to $285.7 million as of December 31, 2019. The increase in stockholders' equity was primarily driven by $34.5 million of net

Table of Contents

income for the nine months ended September 30, 2020, and an increase of $8.6 million of accumulated other comprehensive income. These increases were partially offset by $7.8 million in dividends declared on common stock. Tangible common equity to tangible assets, a non-GAAP financial measure, decreased to 9.78% as of September 30, 2020, from 10.38% as of December 31, 2019. Tangible common equity to tangible assets would have been 11.14% as of September 30, 2020, if PPP loans were excluded.

We strive to maintain an adequate capital base to support our activities in a safe and sound manner while at the same time attempting to maximize stockholder value. Capital adequacy is assessed against the risk inherent in our balance sheet, recognizing that unexpected loss is the common denominator of risk and that common equity has the greatest capacity to absorb unexpected loss.

We are subject to various regulatory capital requirements both at the Company and at the Bank level. Failure to meet minimum capital requirements could result in certain mandatory and possible additional discretionary actions by regulators that, if undertaken, could have an adverse material effect on our financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, specific capital guidelines must be met that involve quantitative measures of assets, liabilities, and certain off-balance sheet items as calculated under regulatory accounting policies. We have consistently maintained regulatory capital ratios at or above the well-capitalized standards.

At September 30, 2020 and December 31, 2019, we met all the capital adequacy requirements to which we were subject. The table below presents the Company’s and the Bank’s regulatory capital ratios as of September 30, 2020 and December 31, 2019:

​

Off-Balance Sheet Arrangements

We are a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of our customers. These financial instruments consist primarily of commitments to extend credit and standby letters of credit. Commitments to extend credit are agreements to lend to customers, generally having fixed expiration dates or other termination clauses that may require payment of a fee. These commitments consist principally of unused commercial and consumer credit lines. Standby letters of credit generally are contingent upon the failure of the customer to perform according to the terms of an underlying contract with a third party. The credit risks associated with commitments to extend credit and standby letters of credit are essentially the same as that involved with extending loans to customers and are subject to normal credit policies. Collateral may be required based on management’s assessment of the customer’s creditworthiness. The fair value of these commitments is considered immaterial for disclosure purposes.

A summary of the contractual amounts of our exposure to off-balance sheet agreements as of September 30, 2020 and December 31, 2019, is as follows:

​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | September 30, | ​ | December 31,
(dollars in thousands) |  | 2020 |  | 2019
Commitments to extend credit | ​ | $ | 596,642 | ​ | $ | 586,365
Standby letters of credit | ​ |  | 7,073 | ​ |  | 8,516
Total | ​ | $ | 603,715 | ​ | $ | 594,881

​

Liquidity

Liquidity management is the process by which we manage the flow of funds necessary to meet our financial commitments on a timely basis and at a reasonable cost and to take advantage of earnings enhancement opportunities. These financial commitments include withdrawals by depositors, credit commitments to borrowers, expenses of our operations, and capital expenditures. Liquidity is monitored and closely managed by our asset and liability committee, or the ALCO, a group of senior officers from the finance, enterprise risk management, deposit, investment, treasury, and lending areas. It is the ALCO’s responsibility to ensure we have the necessary level of funds available for normal operations as well as maintain a contingency funding policy to ensure that potential liquidity stress events are planned for, quickly identified, and management has plans in place to respond. The ALCO has created policies which establish limits and require measurements to monitor liquidity trends, including modeling and management reporting that identifies the amounts and costs of all available funding sources.

As of September 30, 2020, we had on balance sheet liquidity of $311.1 million, compared to $250.7 million as of December 31, 2019. On balance sheet liquidity includes total due from banks, federal funds sold, interest-bearing deposits with banks, unencumbered securities available-for-sale, and over collateralized securities pledging positions.

Table of Contents

The Bank is a member of the FHLB, which provides short- and long-term funding to its members through advances collateralized by real estate related assets and other select collateral, most typically in the form of debt securities. The actual borrowing capacity is contingent on the amount of collateral available to be pledged to the FHLB. As of September 30, 2020, we had no outstanding fed funds purchased from the FHLB and $565.3 million of collateral pledged to the FHLB. Based on this collateral, we were eligible to borrow up to $565.0 million from the FHLB. In addition, we can borrow up to $102.0 million through the unsecured lines of credit we have established with four other banks.

In addition, because the Bank is “well capitalized,” we can accept wholesale deposits up to 20.0% of total assets based on current policy limits. Management believed that we had adequate resources to fund all of our commitments as of September 30, 2020 and December 31, 2019.

Our primary sources of liquidity include liquid assets, as well as unencumbered securities that can be used to collateralize additional funding.

Though remote, the possibility of a funding crisis exists at all financial institutions. The economic impact of COVID-19 could place increased demand on our liquidity if we experience significant credit deterioration and as we meet borrowers’ needs. Accordingly, management has addressed this issue by formulating a liquidity contingency plan, which has been reviewed and approved by both the Bank’s board of directors and the ALCO. The plan addresses the actions that we would take in response to both a short-term and long-term funding crisis.

A short-term funding crisis would most likely result from a shock to the financial system, either internal or external, which disrupts orderly short-term funding operations. Such a crisis would likely be temporary in nature and would not involve a change in credit ratings. A long-term funding crisis would most likely be the result of both external and internal factors and would most likely result in drastic credit deterioration. Management believes that both potential circumstances have been fully addressed through detailed action plans and the establishment of trigger points for monitoring such events.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market risk is the risk of loss arising from adverse changes in the fair value of financial instruments due to changes in interest rates. Interest-rate risk is the risk to earnings and equity value arising from changes in market interest rates and arises in the normal course of business to the extent that there is a divergence between the amount of interest-earning assets and the amount of interest-bearing liabilities that are prepaid/withdrawn, re-price, or mature in specified periods. We seek to achieve consistent growth in net interest income and equity while managing volatility arising from shifts in market interest rates. The ALCO oversees market risk management, monitoring risk measures, limits, and policy guidelines for managing the amount of interest rate risk and its effect on net interest income and capital. The Bank’s board of directors approves policy limits with respect to interest rate risk.

Interest Rate Risk

Interest rate risk management is an active process that encompasses monitoring loan and deposit flows complemented by investment and funding activities. Effective interest rate risk management begins with understanding the dynamic characteristics of assets and liabilities and determining the appropriate interest rate risk position given business activities, management objectives, market expectations and ALCO policy limits and guidelines.

Interest rate risk can come in a variety of forms, including repricing risk, basis risk, yield curve risk and option risk. Repricing risk is the risk of adverse consequences from a change in interest rates that arises because of differences in the timing of when those interest rate changes impact our assets and liabilities. Basis risk is the risk of adverse consequence resulting from unequal change in the spread between two or more rates for different instruments with the same maturity. Yield curve risk is the risk of adverse consequences resulting from unequal changes in the spread between two or more rates for different maturities for the same or different instruments. Option risk in financial instruments arises from embedded options such as options provided to borrowers to make unscheduled loan

prepayments, options provided to debt issuers to exercise call options prior to maturity, and depositor options to make withdrawals and early redemptions.

Management regularly reviews our exposure to changes in interest rates. Among the factors considered are changes in the mix of interest-earning assets and interest-bearing liabilities, interest rate spreads and repricing periods. The ALCO reviews, on at least a quarterly basis, the interest rate risk position.

The interest-rate risk position is measured and monitored at the Bank using net interest income simulation models and economic value of equity sensitivity analysis that capture both short-term and long-term interest-rate risk exposure.

Modeling the sensitivity of net interest income and the economic value of equity to changes in market interest rates is highly dependent on numerous assumptions incorporated into the modeling process. The models used for these measurements rely on estimates of the potential impact that changes in interest rates may have on the value and prepayment speeds on all components of our loan portfolio, investment portfolio, as well as embedded options and cash flows of other assets and liabilities. Balance sheet growth assumptions are also included in the simulation modeling process. The analysis provides a framework as to what our overall sensitivity position is as of our most recent reported position and the impact that potential changes in interest rates may have on net interest income and the economic value of our equity.

Net interest income simulation involves forecasting net interest income under a variety of interest rate scenarios including instantaneous shocks.

The estimated impact on our net interest income as of September 30, 2020 and December 31, 2019, assuming immediate parallel moves in interest rates is presented in the table below.

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | September 30, 2020 | ​ | December 31, 2019 |
​ |  | Following |  | Following |  | Following |  | Following |
​ | ​ | 12 months | ​ | 24 months | ​ | 12 months | ​ | 24 months |
+400 basis points |  | 3.5 | % | −1.7 | % | 5.5 | % | 12.2 | %

−200 basis points |  | N/A | % | N/A | % | N/A | % | N/A | %

​

Management strategies may impact future reporting periods, as actual results may differ from simulated results due to the timing, magnitude, and frequency of interest rate changes, the difference between actual experience, and the characteristics assumed, as well as changes in market conditions. Market based prepayment speeds are factored into the analysis for loan and securities portfolios. Rate sensitivity for transactional deposit accounts is modeled based on both historical experience and external industry studies.

Management uses economic value of equity sensitivity analysis to understand the impact of interest rate changes on long-term cash flows, income, and capital. Economic value of equity is based on discounting the cash flows for all balance sheet instruments under different interest rate scenarios. Deposit premiums are based on external industry studies and utilizing historical experience.

Operational Risk

Operational risk is the risk of loss due to human behavior, inadequate or failed internal systems and controls, and external influences such as market conditions, fraudulent activities, disasters, and security risks. Management continuously strives to strengthen its system of internal controls, enterprise risk management, operating processes and employee awareness to assess the impact on earnings and capital and to improve the oversight of our operational risk.

Compliance Risk

Compliance risk represents the risk of regulatory sanctions, reputational impact or financial loss resulting from failure to comply with rules and regulations issued by the various banking agencies and standards of good banking practice. Activities which may expose us to compliance risk include, but are not limited to, those dealing with the prevention of money laundering, privacy and data protection, community reinvestment initiatives, fair lending challenges resulting from the expansion of our banking center network, employment and tax matters.

Strategic and/or Reputation Risk

Strategic and/or reputation risk represents the risk of loss due to impairment of reputation, failure to fully develop and execute business plans, failure to assess current and new opportunities in business, markets and products, and any other event not identified in the defined risk types mentioned previously. Mitigation of the various risk elements that represent strategic and/or reputation risk is achieved through initiatives to help management better understand and report on various risks, including those related to the development of new products and business initiatives.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

The Company’s management, including our President and Chief Executive Officer and our Chief Financial Officer, have evaluated the effectiveness of our “disclosure controls and procedures” (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934, or the “Exchange Act”), as of the end of the period covered by this report. Based on such evaluation, our President and Chief Executive Officer and our Chief Financial Officer have concluded that, as of the end of such period, the Company’s disclosure controls and procedures were effective as of that date to provide reasonable assurance that the information required to be disclosed by the Company in the reports it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC and that information required to be disclosed by the Company in the reports it files or submits under the Exchange Act is accumulated and communicated to the Company’s management, including its President and Chief Executive Officer and its Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

Changes in Internal Control over Financial Reporting

There have not been any changes in the Company’s internal control over financial reporting (as such term is defined in Rule 13a-15(f) under the Exchange Act) during the fiscal quarter to which this report relates that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

PART II—OTHER INFORMATION

Item 1 – Legal Proceedings

There are no material pending legal proceedings, other than ordinary routine litigation incidental to the business of the Company or its subsidiaries, to which we or any of our subsidiaries is a party or to which our property is the subject. The Company does not know of any proceeding contemplated by a governmental authority against the Company or any of its subsidiaries. ​

Item 1A – Risk Factors

In addition to the risk factors set forth under Part I, Item 1A “Risk Factors” in the Company’s Form 10-K for the fiscal year ended December 31, 2019, the following risk factors apply to the Company:

The outbreak of Coronavirus Disease 2019, or COVID-19, has led to an economic recession and other severe disruptions to the U.S. economy and has adversely impacted certain industries in which our clients operate and impaired their ability to fulfill their financial obligations to us. As a result, we are starting to see the impact from COVID-19 on our business, and we believe that it will be significant, adverse, and potentially material.

Currently, COVID-19 is spreading through the United States and the world. The spread of COVID-19 has caused severe disruptions to the U.S. economy at large, and for small businesses, in particular, which has disrupted our operations. We are starting to see the impact from COVID-19 on our business, and we believe that it will be significant, adverse, and potentially material. The responses on the part of the U.S. and global governments and populations have created a recessionary environment, reduced economic activity, and caused significant volatility in the global stock markets. We expect that we will experience significant disruptions across our business due to these effects, leading to decreased earnings and significant loan defaults and slowdowns in our loan collections. We expect retirement and benefit services and wealth management asset based revenue will be adversely affected by reduced assets under administration and assets under management, and we also expect increased unemployment and recessionary concerns will adversely affect mortgage originations and mortgage banking revenue in future periods.

The outbreak of COVID-19 has resulted in a decline in our clients’ businesses, a decrease in consumer confidence, an increase in unemployment, and a disruption in the services provided by our vendors. Continued disruptions to our clients’ businesses could result in increased risk of delinquencies, defaults, foreclosures, and losses on our loans and declines in assets under management and wealth management revenues, negatively impact regional economic conditions, result in declines in local loan demand, liquidity of loan guarantors, the value of loan collateral (particularly in real estate), loan originations, and deposit availability and negatively impact the implementation of our growth strategy. Although the U.S. government initially introduced a number of programs designed to soften the impact of COVID-19 on small businesses, the lack of additional programs may cause our borrowers to not be able to satisfy their financial obligations to us.

In addition, COVID-19 has impacted and likely will continue to impact the financial ability of businesses and consumers to borrow money, which would negatively impact loan volumes. Certain of our borrowers are in, or have exposure to, the retail, restaurant, and hospitality industries and are located in areas that are, or were, quarantined or under stay-at-home orders, and COVID-19 may also have an adverse effect on our commercial real estate portfolio, particularly with respect to real estate with exposure to these industries, and consumer loan portfolios. As COVID-19 cases have begun to surge in recent months, any new or prolonged quarantine or stay-at-home orders would have a negative adverse impact on these borrowers and their revenue streams, which consequently impacts their ability to meet their financial obligations to us and could result in loan defaults.

The ultimate extent of the COVID-19 pandemic’s effect on our business will depend on many factors, primarily including the speed and extent of any recovery from the related economic recession. Among other things, this will depend on the duration of the COVID-19 pandemic, particularly in our markets, the development and distribution of vaccines, therapies and other public health initiatives to control the spread of the disease, the nature and size of federal

economic stimulus and other governmental efforts, and the possibility of additional state lockdown or stay-at-home orders in our markets in response to the recent surge in the number of COVID-19 cases.

As a result of the COVID-19 pandemic we may experience adverse financial consequences due to a number of other factors, including but not limited to:

| ● | a further and sustained decline in our stock price or the occurrence of what management would deem to be a triggering event that could, under certain circumstances, cause management to perform impairment testing on our goodwill and other intangible assets that could result in an impairment charge being recorded for that period, and adversely impact our results of operations and the ability of the Bank to pay dividends to us;

| ● | the negative effect on earnings resulting from the Bank modifying loans and agreeing to loan payment deferrals due to the COVID-19 crisis;

| ● | increased demand on our liquidity as we meet borrowers’ needs, experience significant credit deterioration, and cover expenses related to our business continuity plan;

| ● | the potential for reduced liquidity and its negative affect on our capital and leverage ratios;

| ● | the modification of our business practices, including with respect to branch operations, employee travel, employee work locations, participation in meetings, events and conferences, and related changes for our vendors and other business partners;

| ● | the disruption of our acquisition strategy due to the uncertainties created by the pandemic and challenges to our own business, which could limit or delay our future growth plans;

| ● | increases in federal and state taxes as a result of the effects of the pandemic and stimulus programs on governmental budgets;

| ● | an increase in FDIC premiums if the agency experiences additional resolution costs relating to bank failures;

| ● | increased cyber and payment fraud risk due to increased online and remote activity; and

| ● | other operational failures due to changes in our normal business practices because of the pandemic and governmental actions to contain it.

Overall, we believe that the economic impact from COVID-19 will be severe and could have a material and adverse impact on our business and result in significant losses in our loan portfolio, all of which would adversely and materially impact our earnings and capital. Even after the COVID-19 pandemic has subsided, we may continue to experience materially adverse impacts to our business as a result of the global economic impact of the COVID-19 pandemic, including the availability of credit, adverse impacts on liquidity and any recession that has occurred or may occur in the future. There are no comparable recent events that provide guidance as to the effect the spread of COVID-19 as a global pandemic may have, and, as a result, the ultimate impact of the pandemic is highly uncertain and subject to change.

The U.S. government and banking regulators, including the Federal Reserve, have taken a number of unprecedented actions in response to the COVID-19 pandemic, which could ultimately have a material adverse effect on our business and results of operations

On March 27, 2020, President Trump signed into law the Coronavirus Aid, Relief and Economic Security Act, or CARES Act, which established a $2.0 trillion economic stimulus package, including cash payments to individuals,

67

Table of Contents

supplemental unemployment insurance benefits and a $349 billion loan program administered through the SBA referred to as the PPP. In addition to implementing the programs contemplated by the CARES Act, the federal bank regulatory agencies have issued a steady stream of guidance in response to the COVID-19 pandemic and have taken a number of unprecedented steps to help banks navigate the pandemic and mitigate its impact. These include, without limitation:

| ● | requiring banks to focus on business continuity and pandemic planning;

| ● | adding pandemic scenarios to stress testing;

| ● | encouraging bank use of capital conservation buffers and reserves in lending programs;

| ● | permitting certain regulatory reporting extensions;

| ● | reducing margin requirements on swaps;

| ● | permitting certain otherwise prohibited investments in investment funds;

| ● | issuing guidance to encourage banks to work with customers affected by the pandemic and encourage loan workouts; and

| ● | providing credit under the CRA for certain pandemic-related loans, investments, and public service.

The COVID-19 pandemic has significantly affected the financial markets and the Federal Reserve has taken a number of actions in response. In March 2020, the Federal Reserve dramatically reduced the target federal funds rate and announced a $700 billion quantitative easing program in response to the expected economic downturn caused by the COVID-19 pandemic. In addition, the Federal Reserve reduced the interest that it pays on excess reserves. We expect that these reductions in interest rates, especially if prolonged, could adversely affect our net interest income and our net interest margin and our profitability. The Federal Reserve also launched the Main Street Lending Program, which offers deferred interest on four-year loans to small and mid-sized businesses. The full impact of the COVID-19 pandemic on our business activities as a result of new government and regulatory laws, policies, programs, and guidelines, as well as market reactions to such activities, remains uncertain but may ultimately have a material adverse effect on our business and results of operations.

COVID-19 has disrupted banking and other financial activities in the areas in which we operate and could potentially create widespread business continuity issues for us.

The COVID-19 pandemic has negatively impacted the ability of our employees and clients to engage in banking and other financial transactions in the geographic areas in which we operate and could create widespread business continuity issues for us. We also could be adversely affected if key personnel or a significant number of employees were to become unavailable due to the effects and restrictions of an outbreak or escalation of the COVID-19 pandemic in our market areas, including because of illness, quarantines, government actions or other restrictions in connection with the COVID-19 pandemic. Although we have business continuity plans and other safeguards in place, there is no assurance that such plans and safeguards will be effective. Further, we rely upon third-party vendors to conduct business and to process, record, and monitor transactions. If any of these vendors are unable to continue to provide us with these services, it could negatively impact our ability to serve our clients.

As a participating lender in the PPP, we are subject to additional risks of litigation from our clients or other parties regarding our processing of loans for the PPP and risks that the SBA may not fund some or all PPP loan guarantees.

The CARES Act included a $349 billion loan program administered through the SBA referred to as the PPP. Under the PPP, small businesses and other entities and individuals could apply for loans from existing SBA lenders and other approved regulated lenders that enrolled in the program, subject to numerous limitations and eligibility criteria. The Bank participated as a lender in the PPP. The PPP opened on April 3, 2020; however, because of the short

68

Table of Contents

timeframe between the passing of the CARES Act and the opening of the PPP, there is some ambiguity in the laws, rules, and guidance regarding the operation of the PPP, which exposes us to risks relating to noncompliance with the PPP. On April 24, 2020, an additional $310 billion in funding for PPP loans was authorized and such funds became available for PPP loans beginning on April 27, 2020.

Since the opening of the PPP, several other larger banks have been subject to litigation regarding the process and procedures that such banks used in processing applications for the PPP and claims related to agent fees. If any such litigation is filed against us and is not resolved in a manner favorable to us, it may result in significant financial liability or adversely affect our reputation. In addition, litigation can be costly, regardless of outcome. Any financial liability, litigation costs, or reputational damage caused by the PPP related litigation could have a material adverse impact on our business, financial condition, and results of operations.

We also have credit risk on PPP loans if a determination is made by the SBA that there is a deficiency in the manner in which the loan was originated, funded, or serviced by the Bank, such as an issue with the eligibility of a borrower to receive a PPP loan, which may or may not be related to the ambiguity in the laws, rules, and guidance regarding the operation of the PPP. In the event of a loss resulting from a default on a PPP loan and a determination by the SBA that there is a deficiency in the manner in which the PPP loan was originated, funded, or serviced by us, the SBA may deny its liability under the guaranty, reduce the amount of the guaranty, or if it has already paid under the guaranty, seek recovery of any loss related to the deficiency from us.
