(1)Summary of Significant Accounting Policies

(a) Organization of the Company and Basis of Presentation

The accompanying unaudited consolidated interim financial statements and these notes should be read in conjunction with the December 31, 2021 audited consolidated financial statements and notes thereto contained in the 2021 Annual Report on Form 10-K of Enterprise Bancorp, Inc. (the "Company," "Enterprise," "we," or "our") as filed with the Securities and Exchange Commission (the "SEC") on March 10, 2022 (the "2021 Annual Report on Form 10-K"). The Company has not materially changed its significant accounting policies from those disclosed in its 2021 Annual Report on Form 10-K. See Item (c), "Recent Accounting Pronouncements," below in this Note 1.

The accompanying unaudited consolidated interim financial statements of the Company include the accounts of the Company and its wholly owned subsidiary, Enterprise Bank and Trust Company, commonly referred to as Enterprise Bank (the "Bank"). The Bank is a Massachusetts trust company and state chartered commercial bank organized in 1989. Substantially all of the Company's operations are conducted through the Bank and its subsidiaries.

The Bank's subsidiaries include Enterprise Insurance Services, LLC and Enterprise Wealth Services, LLC, both organized under the laws of the State of Delaware, to engage in insurance sales activities and offer non-deposit investment products and services, respectively. In addition, the Bank has the following subsidiaries that are incorporated in the Commonwealth of Massachusetts and classified as security corporations in accordance with applicable Massachusetts General Laws: Enterprise Security Corporation; Enterprise Security Corporation II; and Enterprise Security Corporation III. The security corporations, which hold various types of qualifying securities, are limited to conducting investment activities that the Bank itself would be allowed to conduct under applicable laws. The services offered through the Bank and its subsidiaries are managed as one strategic unit and represent the Company's only reportable operating segment.

The accompanying unaudited consolidated interim financial statements, and notes thereto, in this Quarterly Report on Form 10-Q for the quarterly period ended September 30, 2022 (this "Form 10-Q"), have been prepared in accordance with U.S. generally accepted accounting principles ("GAAP") for interim financial information and the SEC instructions for Quarterly Reports on Form 10-Q. In the opinion of management, the accompanying unaudited consolidated interim financial statements reflect all necessary adjustments, consisting of normal recurring accruals and elimination of intercompany balances, for a fair presentation. Certain previous years' amounts in the unaudited consolidated financial statements, and notes thereto, have been reclassified to conform to the current year's presentation. Interim results are not necessarily indicative of results to be expected for the entire year, or any future period.

(b) Uses of Estimates

In preparing the unaudited consolidated interim financial statements in conformity with GAAP, management is required to exercise judgment in determining many of the methodologies, assumptions and estimates to be utilized. These assumptions and estimates affect the reported values of assets and liabilities as of the balance sheet dates and income and expenses for the period then ended. As future events and their effects cannot be determined with precision, actual results could differ significantly from these estimates should the assumptions and estimates used be incorrect or change over time due to changes in circumstances. Changes in those estimates resulting from continuing changes in the economic environment and other factors will be reflected in the consolidated financial statements and results of operations in future periods.

As discussed in the Company's 2021 Annual Report on Form 10-K, the most significant areas in which management applies critical assumptions and estimates are: the estimates of the allowance for credit losses ("ACL") for loans and available for sale securities, the reserve for unfunded commitments, and the impairment review of goodwill. Refer to Note 1, "Summary of Significant Accounting Policies," to the Company's audited consolidated financial statements included in the Company's 2021 Annual Report on Form 10-K for accounting policies related to these significant estimates.

(c) Recent Accounting Pronouncements

Accounting pronouncements not yet adopted by the Company

In March 2022, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2022-01, Derivatives and Hedging (Topic 815): Fair Value Hedging—Portfolio Layer Method. This ASU clarifies the guidance on fair value hedge accounting of interest rate risk for portfolios of financial assets. The ASU amends the guidance in ASU 2017-12 Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities, that, among other things, established the "last-of-layer" method for making the fair value hedge accounting for these portfolios more accessible. ASU

Table of Contents ENTERPRISE BANCORP, INC. Notes to the Unaudited Consolidated Interim Financial Statements

2022-01 renames that method the "portfolio layer" method and addresses feedback from stakeholders regarding its application. For the Company, ASU 2022-01 is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. The Company is currently assessing the impact of this ASU and expects that this ASU will not have a material impact to the consolidated financial statements.

In March 2022, the FASB issued ASU 2022-02, Financial Instruments—Credit Losses (Topic 326), Troubled Debt Restructurings and Vintage Disclosures. This ASU eliminates the accounting guidance for troubled debt restructurings by creditors that have adopted the current expected credit loss ("CECL") methodology for estimating allowances for credit losses and enhances the disclosure requirements for loan restructurings made with borrowers experiencing financial difficulty. In addition, the amendments require a public business entity to disclose current-period gross charge-offs for financing receivables and net investment in leases by year of origination in the vintage disclosures. For the Company, ASU 2022-02 is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. The Company is currently assessing the impact of this ASU and expects that implementation will not have a material impact to the consolidated financial statements.

Accounting pronouncements adopted by the Company

In August 2021, the FASB issued ASU 2021-06, Presentation of Financial Statements (Topic 205), Financial Services—Depository and Lending (Topic 942), and Financial Services—Investment Companies (Topic 946). This ASU incorporates recent SEC rule changes into the FASB Codification, including SEC Final Rule Releases No. 33-10786, Amendments to Financial Disclosures about Acquired and Disposed Businesses, and No. 33-10835, Update of Statistical Disclosures for Bank and Savings and Loan Registrants. The rules reduce the required reporting periods to align them with the relevant financial statement periods required by SEC rules and requires certain statistical disclosures for annual periods, and interim disclosures if a material change in the information, or trend, has occurred. The amendments in this update are effective upon addition to the FASB Codification and apply to fiscal years ending on or after December 15, 2021. However, voluntary early compliance is permitted upon the effective date, provided that the rules are applied in their entirety. The amended disclosures did not have a material impact on the consolidated financial statements.

(d) Subsequent Events

The Company has evaluated subsequent events and transactions from September 30, 2022, through the date this Form 10-Q was filed with the SEC for potential recognition or disclosure as required by GAAP and determined there were no material subsequent events requiring recognition or disclosure.

At September 30, 2022, management performed its quarterly analysis of all securities with unrealized losses and determined that the losses were primarily attributable to significant increases in market interest rates experienced during the first nine months of 2022. Management concluded that no ACL for available-for-sale securities was necessary as of September 30, 2022 and anticipates they will mature or be called at par value.

Accrued interest receivable on available-for-sale debt securities, included in the "Accrued Interest Receivable" line item on the Company's Consolidated Balance Sheets, amounted to $4.4 million and $3.2 million at September 30, 2022 and December 31, 2021, respectively.

The contractual maturity distribution at September 30, 2022 of debt securities was as follows:    

(Dollars in thousands)	Amortized Cost		Fair Value
Due in one year or less	$	13,464	$	13,407
Due after one, but within five years	198,843		189,724
Due after five, but within ten years	290,032		248,284
Due after ten years	448,542		375,800
Total debt securities	$	950,881	$	827,215

Scheduled contractual maturities shown above may not reflect the actual maturities of the investments. The actual MBS/CMO cash flows likely will be faster than presented above due to prepayments and amortization. Similarly, included in the table above are callable securities, comprised of municipal securities and corporate bonds, with a fair value of $159.0 million, which can be redeemed by the issuers prior to the maturity presented above. Management considers these factors when evaluating the interest-rate risk in the Company's asset-liability management program.

From time to time, the Company may pledge debt securities as collateral for deposit account balances of municipal customers, and for borrowing capacity with the FHLB and the Federal Reserve Bank of Boston ("FRB"). The fair value of debt securities pledged as collateral for these purposes was $813.0 million and $949.3 million at September 30, 2022 and December 31, 2021, respectively.

The Company had no sales of debt securities during the three months ended September 30, 2022 or September 30, 2021. Sales of debt securities for the nine months ended September 30, 2022 and September 30, 2021 are summarized as follows:     

	Nine months ended September 30,
(Dollars in thousands)		2022		2021

_________________________________________

(1)Amortized cost of investments sold is determined on a specific identification basis and includes pending trades based on trade date, if applicable.

Equity Securities

The Company held equity securities with a fair value of $3.8 million at September 30, 2022 and $1.8 million at December 31, 2021. At September 30, 2022, the equity portfolio consisted of investments in broad-based equity index funds and common stock of entities in the financial services industry. The equity portfolio also included mutual funds held in conjunction with the Company's supplemental executive retirement and deferred compensation plan.

Gains and losses on equity securities for the three and nine months ended September 30, 2022 and September 30, 2021 are summarized as follows:

The ratio of non-accrual loans to total loans amounted to 0.18% and 0.91% at September 30, 2022 and December 31, 2021, respectively. The decline in non-accrual loans at September 30, 2022 compared to December 31, 2021 was due primarily to two commercial relationships that were returned to accrual status due to improved financial strength and consistent payment history.

Non-accrual loans that were not adversely classified amounted to $3 thousand at both September 30, 2022 and December 31, 2021. These balances primarily represented the guaranteed portions of non-performing SBA loans.

At September 30, 2022 and December 31, 2021, additional funding commitments for non-accrual loans were not material.

Collateral dependent loans

The carrying value of collateral dependent loans amounted to $26.4 million at September 30, 2022 compared to $34.6 million at December 31, 2021. Total accruing collateral dependent loans amounted to $21.0 million while non-accrual collateral dependent loans amounted to $5.4 million as of September 30, 2022. Total accruing collateral dependent loans amounted to $8.4 million while non-accrual collateral dependent loans amounted to $26.2 million as of December 31, 2021.

Troubled debt restructurings ("TDRs")

Total TDR loans as of September 30, 2022 amounted to $8.6 million compared to $16.4 million as of December 31, 2021. At September 30, 2022 and December 31, 2021, TDR loans on accrual status amounted to $5.8 million and $8.6 million, respectively, and TDR loans included in non-accrual loans amounted to $2.8 million and $7.8 million, respectively.

The Company continues to work with customers and enter into loan modifications (which may or may not be TDRs) to the extent deemed to be necessary or appropriate while attempting to achieve the best mutual outcome given the individual financial circumstances and future prospects of the borrower.

At September 30, 2022 and September 30, 2021, additional funding commitments for TDR loans were not material.

Reserve for unfunded commitments

The Company's reserve for unfunded commitments amounted to $4.1 million at September 30, 2022 and $3.7 million at December 31, 2021. Management believes that the Company's ACL for loans and reserve for unfunded commitments were adequate as of September 30, 2022.

Table of Contents ENTERPRISE BANCORP, INC. Notes to the Unaudited Consolidated Interim Financial Statements

At September 30, 2022 and December 31, 2021, the Company had no consumer mortgage loans secured by residential real estate properties for which formal foreclosure proceedings were in process according to local requirements of the applicable jurisdictions.

(5)Leases

As of September 30, 2022, the Company had 16 facilities contracted under various non-cancelable operating leases, most of which provide options to the Company to extend the lease periods and include periodic rent adjustments.

Lease expense for the three and nine months ended September 30, 2022 amounted to $397 thousand and $1.2 million, respectively. Lease expense for the three and nine months ended September 30, 2021 amounted to $414 thousand and $1.1 million, respectively. Variable lease costs and short-term lease expenses included in lease expense during these periods were immaterial.

The weighted average remaining lease term for operating leases at September 30, 2022 and September 30, 2021 was 29.7 years and 28.8 years, respectively. The weighted average discount rate was 3.44% at September 30, 2022 and 3.61% at September 30, 2021.

At September 30, 2022, the remaining undiscounted cash flows by year of these lease liabilities were as follows:

(Dollars in thousands)	Operating Leases
2022 (three remaining months)	$	359
2023	1,406

All of the Company's deposits outstanding at both September 30, 2022 and December 31, 2021 were customer deposits. Customer deposits include reciprocal balances from checking, money market deposits and CDs received from participating banks in nationwide deposit networks due to our customers electing to participate in Company offered programs which allow for enhanced Federal Deposit Insurance Corporation ("FDIC") deposit insurance. Essentially, the equivalent of the customers' original deposited funds comes back to the Company and are carried within the appropriate category under deposits. The Company's balances in these reciprocal products were $580.6 million and $546.7 million at September 30, 2022 and December 31, 2021, respectively.

(8)    Derivatives and Hedging Activities

See Note 9, "Derivatives and Hedging," to the Company's audited consolidated financial statements contained in the 2021 Annual Report on Form 10-K. 

The tables below present a summary of the Company's derivative financial instruments, notional amounts and fair values for the periods presented:

__________________________________________

(1)     Accrued interest balances related to the Company's interest-rate swaps are not included in the fair values above and are immaterial.

The Company had no derivative fair value or cash flow hedges at either September 30, 2022 or December 31, 2021.

Each back-to-back interest-rate swap consists of two interest-rate swaps (a customer swap and offsetting counterparty swap) and amounted to a total number of 4 interest-rate swaps outstanding at September 30, 2022 and 10 at December 31, 2021. As a result of this offsetting relationship, there were no net gains or losses recognized in income on back-to-back swaps during the nine months ended September 30, 2022 or September 30, 2021.

22

Table of Contents ENTERPRISE BANCORP, INC. Notes to the Unaudited Consolidated Interim Financial Statements

Interest-rate swaps with counterparties are subject to master netting agreements, while interest-rate swaps with customers are not. At September 30, 2022, all the back-to-back swaps with the counterparty were in asset positions and at December 31, 2021, all the back-to-back swaps with the counterparty were in liability positions, therefore there was no netting reflected in the Company's Consolidated Balance Sheets as of the respective dates.

Credit Risk

The Company had one interest-rate swap counterparty that was rated A and A2 by Standard & Poor's and Moody's, respectively, at September 30, 2022. When the Company has credit risk exposure, collateral is posted by the counterparty. Collateral posted by counterparties is restricted and not considered an asset of the Company, therefore, it is not carried on the Company's Consolidated Balance Sheets. If the Company posts collateral, the restricted cash is carried on the Company's Consolidated Balance Sheets. The Company had credit risk exposure relating to interest-rate swaps with counterparties of $836 thousand and counterparties posted cash collateral of $712 thousand at September 30, 2022. At December 31, 2021 the Company had no credit risk exposure relating to interest-rate swaps with counterparties and posted restricted cash collateral of $840 thousand.

Customer-related credit risk on back-to-back swaps is minimized by the cross collateralization of the loan and the interest-rate swap agreement to the customer's underlying collateral.

Credit-risk-related Contingent Features

There have been no material changes to the credit-risk-related contingent provisions contained within the Company's interest-rate swaps with counterparties since December 31, 2021.

As of September 30, 2022, the fair value of derivatives related to these agreements was at a net asset position of $836 thousand, which excludes any adjustment for nonperformance risk. The Company has minimum collateral posting thresholds with certain of its derivative counterparties and as of September 30, 2022, has not posted collateral related to these agreements.

Other Derivative Related Activity

At both September 30, 2022 and December 31, 2021, the Company had one participation loan where the originating bank utilizes a back-to-back interest-rate swap structure. At September 30, 2022, management considers the risk of material swap-loss exposure related to this participation loan to be unlikely based on the borrower's financial and collateral strength.

Interest-rate lock commitments related to the origination of mortgage loans that will be sold are considered derivative instruments. The commitments to sell loans are also considered derivative instruments. At September 30, 2022 and December 31, 2021, the estimated fair value of the Company's interest-rate lock commitments and commitments to sell these mortgage loans were deemed immaterial.

(9) Regulatory Capital Requirements

Capital Raised and Capital Adequacy Requirements

As of September 30, 2022 and December 31, 2021, the Company met the definition of "well-capitalized" under the applicable regulations of the Board of Governors of the Federal Reserve System and the Bank qualified as "well-capitalized" under the prompt corrective action regulations of Basel III and the FDIC.

__________________________________________

(1)Before application of the capital conservation buffer of 2.50% as of September 30, 2022, and December 31, 2021. See discussion      below.

(2)For the Bank to qualify as "well-capitalized," it must maintain at least the minimum ratios listed under the regulatory prompt corrective action framework. This framework does not apply to the Company.

The Company is subject to the Basel III capital ratio requirements which include a "capital conservation buffer" of 2.50% above the regulatory minimum risk-based capital adequacy requirements shown above. If a banking organization dips into its capital conservation buffer it may be restricted in its activities, including its ability to pay dividends and discretionary bonus payments to its executive officers. Both the Company's and the Bank's actual ratios, as outlined in the table above, exceeded the Basel III risk-based capital requirement with the capital conservation buffer as of September 30, 2022.

The Company utilizes the Black-Scholes option valuation model to determine the per share grant date fair value of stock option grants.

The Company recognized stock-based compensation expense related to stock option awards of $53 thousand and $153 thousand for the three and nine months ended September 30, 2022, respectively, compared to $48 thousand and $140 thousand for the three and nine months ended September 30, 2021, respectively.

Restricted Stock Awards

Restricted stock awards are granted at the market price of the Company's common stock on the date of the grant. Employee restricted stock awards generally vest over four years in equal portions beginning on or about the first anniversary date of the restricted stock award or are performance-based restricted stock awards that vest upon the Company achieving certain predefined performance objectives. Non-employee director restricted stock awards generally vest over two years in equal portions beginning on or about the first anniversary date of the restricted stock award.

The table below provides a summary of restricted stock awards granted during the periods indicated:

	Nine months ended September 30,
Restricted Stock Awards (number of underlying shares)	2022		2021
Two-year vesting	8,823		8,109
Four-year vesting	22,116		24,307
Performance-based vesting	22,254		21,559
Total restricted stock awards granted	53,193		53,975
Weighted average grant date fair value	$	38.57	$	32.73

Stock-based compensation expense recognized in association with stock awards, mainly restricted stock awards, amounted to $500 thousand and $1.4 million for the three and nine months ended September 30, 2022, respectively, compared to $455 thousand and $1.2 million for the three and nine months ended September 30, 2021, respectively.

Stock in Lieu of Directors' Fees

Non-employee members of the Company's Board may opt to receive newly issued shares of the Company's common stock in lieu of cash compensation for attendance at meetings of the Board and committees of the Board. Stock-based compensation expense related to these directors' fees amounted to $56 thousand and $190 thousand for the three and nine months ended September 30, 2022, respectively, compared to $56 thousand and $179 thousand for the three and nine months ended September 30, 2021, respectively.

(12)Earnings per Share

The table below presents basic earnings per share and the increase in average shares outstanding, using the treasury stock method, for the diluted earnings per share calculation for the periods indicated:

	Three months ended September 30,		Nine months ended September 30,
	2022	2021	2022	2021
Basic weighted average common shares outstanding	12,119,348	12,022,610	12,094,613	11,997,199
Dilutive shares	37,347	42,490	48,855	41,362
Diluted weighted average common shares outstanding	12,156,695	12,065,100	12,143,468	12,038,561

There were 49,321 and 34,473 stock options outstanding for the three and nine months ended September 30, 2022, respectively, that were determined to be anti-dilutive and therefore excluded from the calculation of dilutive shares for those periods. There were 55,777 and 77,023 stock options outstanding for the three and nine months ended September 30, 2021, respectively, that were determined to be anti-dilutive and therefore excluded from the calculation of dilutive shares for the respective periods. These stock options, which were not dilutive, may potentially dilute earnings per share in the future.

Unvested participating restricted awards amounted to 120,728 shares and 113,871 shares as of September 30, 2022 and December 31, 2021, respectively.

(13)Fair Value Measurements

The FASB defines the fair value of an asset or liability to be the price which a seller would receive in an orderly transaction between market participants (an exit price) and also establishes a fair value hierarchy segregating fair value measurements using three levels of inputs: (Level 1) quoted market prices in active markets for identical assets or liabilities; (Level 2) significant other observable inputs, including quoted prices for similar items in active markets, quoted prices for identical or similar items in markets that are not active, inputs such as interest rates and yield curves, volatilities, prepayment speeds, credit risks and default rates which provide a reasonable basis for fair value determination or inputs derived principally from observed market data; and (Level 3) significant unobservable inputs for situations in which there is little, if any, market activity for the asset or liability. Unobservable inputs must reflect reasonable assumptions that market participants would use in pricing the asset or liability, which are developed based on the best information available under the circumstances.

The Company utilizes third-party pricing vendors to provide valuations on its debt securities.

The Company's equity portfolio fair value is measured based on quoted market prices for the shares; therefore, these securities are categorized as Level 1 within the fair value hierarchy.

The Bank is required to purchase FHLB stock at par value in association with advances from the FHLB. The stock is issued, redeemed, repurchased and transferred by the FHLB only at their fixed par value. This stock is classified as a restricted investment and carried at FHLB par value which management believes approximates fair value; therefore, these securities are categorized as Level 2 measures. 

The fair values for the interest-rate swap assets and liabilities, which is comprised of back-to-back swaps, represent a FASB Level 2 measurement and are based on settlement values adjusted for credit risks and observable market interest-rate curves. Refer also to Note 8, "Derivatives and Hedging Activities," this Form 10-Q, contained above, for additional information on the Company's interest-rate swaps.

Table of Contents ENTERPRISE BANCORP, INC. Notes to the Unaudited Consolidated Interim Financial Statements

For loans individually assessed and deemed to be collateral dependent management has estimated the value and the probable credit loss by comparing the loan's amortized cost against the expected realizable fair value of the collateral (appraised value, or internal analysis, less estimated cost to sell, adjusted as necessary for changes in relevant valuation factors subsequent to the measurement date). Certain inputs used in these assessments, and possible subsequent adjustments, are not always observable, and therefore, collateral dependent loans carried at realizable fair value are categorized as Level 3 within the fair value hierarchy. A specific reserve is assigned to the collateral dependent loan for the amount of management's estimated probable credit loss. The specific reserve assigned to individually evaluated loans that are collateral dependent amounted to $275 thousand at September 30, 2022, compared to $1.0 million at December 31, 2021.

The following table presents additional quantitative information about assets measured at fair value on a non-recurring basis for which the Company utilized Level 3 inputs (significant unobservable inputs for situations in which there is little, if any, market activity for the asset or liability) to determine fair value as of September 30, 2022 and December 31, 2021:

	Fair Value

Overview

Executive Summary

The Company strategically operates with a long-term mindset that is focused on organic growth and supporting such growth by continually investing in our people, products, services, technology, including digital evolution, and both new and existing branches.

Our financial condition at September 30, 2022, as well as the three and nine month results for the periods ended September 30, 2022, have been impacted by significant increases in interest rates resulting from the high inflationary environment and the related 300 basis point increase in the federal funds rate by the Federal Reserve Bank. The impact is addressed as applicable throughout this Item 2, "Management's Discussion and Analysis of Financial Condition and Results of Operations."

Net income for the three months ended September 30, 2022, amounted to $12.0 million, or $0.98 per diluted common share, compared to $9.8 million, or $0.81 per diluted common share, for the three months ended September 30, 2021. The increase was attributable primarily to increases in net interest income of $3.9 million and non-interest income of $1.4 million, partially offset by increases in the provision for credit losses of $972 thousand and non-interest expense of $1.8 million. Net income for the three months ended September 30, 2021, was impacted by a loss of $1.8 million on the termination of swaps used in hedging activities.

Net income for the nine months ended September 30, 2022, amounted to $30.4 million, or $2.50 per diluted common share, compared to $31.3 million, or $2.60 per diluted common share, for the nine months ended September 30, 2021. The decrease was attributable primarily to increases in the provision for credit losses of $3.2 million and non-interest expense of $4.5 million, partially offset by increases in net interest income of $3.7 million and non-interest income of $2.1 million. Significant items impacting net income for the nine months ended September 30, 2022, compared to the nine months ended September 30, 2021, include, a decrease in PPP income, of $14.0 million, and an increase in gains on sales of debt securities, of $934 thousand. The results for the nine months ended September 30, 2021, were impacted by a loss on the extinguishment of subordinated debt and the termination of swaps of $713 thousand and $1.8 million, respectively, both of which were included in non-interest expense, are considered infrequent in nature and did not occur during the nine months ended September 30, 2022.

Total assets amounted to $4.53 billion at September 30, 2022, compared to $4.45 billion at December 31, 2021. Investment securities at fair value declined $127.2 million during the nine months ended September 30, 2022, primarily from a decline in the fair value of debt securities due to the significant increase in market interest rates during the period. Total loans increased $188.7 million consisting of an increase in core loans (non-GAAP) of $257.5 million and a decrease in PPP loans of $68.8 million. Total core loans (non-GAAP) increased 15% versus a year ago, resulting from high customer demand and strong business development efforts.

The non-performing loan to total core loan ratio (non-GAAP) decreased to 0.18% at September 30, 2022 from 0.21% at June 30, 2022 and 1.03% at September 30, 2021. The improvement in the second quarter of 2022 resulted primarily from two commercial relationships that were returned to accrual status due to improved financial strength and consistent payment history.

During the nine months ended September 30, 2022, customer deposits increased $157.8 million, and shareholders’ equity decreased $74.7 million, the latter of which was due primarily to the decrease in the fair value of debt securities held in the Company's securities portfolio due to the significant increase in market interest rates during the period, net of tax.

Non-GAAP Measures

The accompanying unaudited consolidated interim financial statements have been prepared in accordance with GAAP. However, certain financial measures we present are supplemental measures that are not required by or are not presented in accordance with GAAP, which we refer to as "non-GAAP" measures. We refer to any measure that excludes PPP loans as "core" and any measure that excludes PPP loans and interest-earning deposits with banks as "adjusted." The activities which resulted in the Company's use of non-GAAP measures consist of: (1) the Company's origination of over $717 million in short-term PPP loans between April 2020 and May 2021; (2) forgiveness of PPP loans by the SBA which began in November 2020 and continued through September 30, 2022; (3) liquidity, carried as lower-yielding interest-earning deposits with banks, had increased significantly following the trends in customer deposits and PPP loan forgiveness by the SBA over the past two years; and (4) the significant increase in market interest rates during the first nine months of 2022 has resulted in unrealized losses in the Company's available-for-sale debt securities portfolio at September 30, 2022 of $123.7 million and an accumulated other comprehensive loss, included in shareholder's equity, of $95.7 million at September 30, 2022.

These non-GAAP measures are intended to provide the reader with additional supplemental perspectives on operating results, performance trends, and financial condition. Non-GAAP financial measures are not a substitute for GAAP measures; they should be read and used in conjunction with the Company's GAAP financial information. In addition, the non-GAAP financial measures we present may differ from non-GAAP financial measures used by our peers or other companies; therefore, these measures may not be comparable to other similarly titled measures as presented by other companies.

The following tables summarize the reconciliation of GAAP to non-GAAP measures related to the impact of PPP loans on total loans and loan interest income:

Risk Management Framework

Management utilizes a comprehensive enterprise risk management framework that enables a coordinated and structured approach for identifying, assessing and managing risks across the Company and provides reasonable assurance that management has the tools, programs, people, and processes in place to support informed decision making, anticipate risks before they materialize and maintain the Company's risk profile consistent with its strategic planning, and applicable laws and regulations.

See Part I, Item 1, "Business," under the "Risk Management Framework," section of the 2021 Annual Report on Form 10-K for additional information on the Company's key risk mitigation strategies.

In addition to the risks outlined in this Form 10-Q, numerous other factors that could adversely affect the Company's future results of operations and financial condition, and its reputation and business model, are addressed in Part I, Item 1A, "Risk Factors," of the 2021 Annual Report on Form 10-K.

Accounting Policies/Critical Accounting Estimates

As discussed in the Company's 2021 Annual Report on Form 10-K and in this Form 10-Q, the most significant areas in which management applies critical assumptions and estimates are: the estimates of the ACL for loans and available-for-sale securities, the reserve for unfunded commitments and the impairment review of goodwill.

The Company has not materially changed its significant accounting and reporting policies from those disclosed in its 2021 Annual Report on Form 10-K.

Recent Accounting Pronouncements

See Note 1, Item (c), "Recent Accounting Pronouncements," to the Company's unaudited consolidated interim financial statements in this Form 10-Q for information regarding recent accounting pronouncements.

Results of Operations for the three months ended September 30, 2022 and September 30, 2021

Unless otherwise indicated, the reported results are for the three months ended September 30, 2022 with the "prior year period" being the three months ended September 30, 2021. Average yields are presented on an annualized tax equivalent basis.

Net Income

Net income for the three months ended September 30, 2022, amounted to $12.0 million, an increase of $2.1 million, or 22%, compared to the prior year period.

•The increase in net income was due primarily to increases in net interest income of $3.9 million and non-interest income of $1.4 million, partially offset by increases in the provision for credit losses of $972 thousand and non-interest expense of $1.8 million.

•Non-interest income for the prior year quarter was impacted by a loss of $1.8 million on the termination of swaps used in hedging activities. Excluding this charge, non-interest income decreased $402 thousand compared to the prior year quarter.

Net Interest Income

Net interest income for the three months ended September 30, 2022, amounted to $39.8 million, an increase of $3.9 million, or 11%, compared to the three months ended September 30, 2021.

•The increase in net interest income was due largely to increases in loan income excluding PPP income (non-GAAP), of $6.3 million, investment securities income of $835 thousand, and other interest-earning asset income of $1.8 million, partially offset by a decrease in PPP income of $4.5 million and an increase in deposit interest expense of $598 thousand.

•PPP income amounted to $437 thousand for the three months ended September 30, 2022, compared to $4.9 million for the three months ended September 30, 2021. PPP loans outstanding amounted to $2.7 million at September 30, 2022, compared to $148.2 million at September 30, 2021. The decline in balance outstanding was due to the continued forgiveness of PPP loans by the SBA during the period.

37

Net Interest Margin

Tax-equivalent net interest margin ("net interest margin") was 3.61% for the three months ended September 30, 2022, compared to 3.45% and 3.39% for the three months ended June 30, 2022 and September 30, 2021, respectively.

Key items impacting net interest margin for the three months ended September 30, 2022, compared to the prior year period, included:

•Average interest-earning deposits with banks decreased $302.9 million, or 45%, while the yield increased 202 basis points. The decrease in average balance resulted primarily from the funding of growth in the Company's investment and core loan portfolios, partially offset by funds received from the forgiveness of PPP loans by the SBA. The increase in yield reflected the 300 basis point increase in the federal funds rate during the first nine months 2022.

•Average investment securities at fair value increased $274.2 million, or 40%, while the tax-equivalent yield decreased 35 basis points. The changes in average balance and yield resulted primarily from investment security purchases in the second half of 2021 when market interest rates were lower than the portfolio yield at that time.

•Average loans increased $193.7 million, or 7%, while the tax-equivalent yield decreased 4 basis points.

◦Average PPP loans outstanding decreased $216.5 million, or 97%, due to the continued forgiveness of PPP loans by the SBA during the period.

◦Average core loans (non-GAAP) increased $410.2 million, or 15%, and the yield increased 25 basis points. The increase in average balance resulted primarily from growth in the commercial and residential real estate portfolios. Core loan yields in the current quarter have benefited primarily from the 300 basis point increase in the prime lending rate during the first nine months of 2022 and to a lesser extent higher market interest rates over the respective prior year period.

•Average total deposits increased $153.9 million, or 4%, and the yield increased 5 basis points. The increase in yield reflected higher market rates in 2022.

Adjusted net interest margin (non-GAAP), which excludes PPP loans and interest-earning deposits with banks, was 3.71% for the three months ended September 30, 2022, compared to 3.55% and 3.68% for the three months ended June 30, 2022 and September 30, 2021, respectively.

•The 16 basis point increase from the three months ended June 30, 2022 to the three months ended September 30, 2022 reflected primarily an increase in loan yields from increases in the prime lending and to a lesser extent higher market interest rates on fixed rate loan originations which collectively exceeded increases in deposit costs.

•The 13 basis point decrease from September 30, 2021 to June 30, 2022 reflected primarily significant growth in investment securities and fixed rate loans at market interest rates which were below portfolio yields, partially offset by a decrease in the cost of deposits.

Refer to the June 30, 2022 10-Q for further disclosure on the calculation of adjusted margin for the respective period.

Interest-rate risk is reviewed in detail in Item 3, "Quantitative and Qualitative Disclosures About Market Risk," below.

Rate / Volume Analysis

The following table sets forth, on a tax-equivalent basis, the extent to which changes in interest rates and changes in the average balances of interest-earning assets and interest-bearing liabilities have affected interest income and expense during the three months ended September 30, 2022, compared to the three months ended September 30, 2021. For each category of interest-earning assets and interest-bearing liabilities, information is provided on changes attributable to: (1) volume (change in average portfolio balance multiplied by prior period average rate); and (2) interest-rate (change in average interest-rate multiplied by prior period average balance). Changes attributable to the combined impact of volume and rate have been allocated proportionately based on absolute value to the changes due to volume and the changes due to rate.

Provision for Credit Losses

The provision for credit losses for the three months ended September 30, 2022, amounted to $1.0 million, compared to $28 thousand for the three months ended September 30, 2021.

•The provision for the three months ended September 30, 2022, consisted of $560 thousand for loans outstanding and $440 thousand for reserves on unfunded commitments (included in other liabilities).

•The majority of the provision for credit losses during the third quarter of 2022 related to growth in the Company's loan portfolio and in off-balance sheet commitments related primarily to commercial construction lending.

The provision for credit losses is a significant factor in the Company's operating results. For further discussion regarding the provision for credit losses and management's assessment of the adequacy of the ACL see "Asset Quality," and "ACL for Loans" under "Financial Condition" in this Item 2, below.

Non-Interest Income

Non-interest income for the three months ended September 30, 2022, amounted to $4.5 million, an increase of $1.4 million, or 47%, compared to the three months ended September 30, 2021.

•Non-interest income in the prior year period included a loss on the termination of swaps used in hedging activities of $1.8 million. Excluding this item, non-interest income decreased $402 thousand, or 8%, resulting primarily from decreases in wealth management fees of $142 thousand, gains on sales of loans of $169 thousand, losses on equity securities of $199 thousand, and other income of $176 thousand, partially offset by an increase in deposit and interchange fees of $232 thousand.

Non-Interest Expense

Non-interest expense for the three months ended September 30, 2022, amounted to $27.5 million, an increase of $1.8 million, or 7%, compared to the three months ended September 30, 2021.

•The increase in non-interest expense over the respective periods resulted primarily from increases in salaries and employee benefits of $1.7 million and other operating expenses of $275 thousand, partially offset by a decrease in occupancy and equipment expenses of $268 thousand.

Income Taxes

The effective tax rate for the three months ended September 30, 2022, was 24.1%, compared to 25.3% for the three months ended September 30, 2021. Tax expense for the three months ended September 30, 2022, benefited from a lower effective tax rate compared to the prior year period due to increases in tax-exempt income and lower-taxed income at the Bank's security corporation subsidiaries.

Results of Operations for the nine months ended September 30, 2022 and September 30, 2021

Unless otherwise indicated, the reported results are for the nine months ended September 30, 2022 with the "prior year period," being the nine months ended September 30, 2021. Average yields are presented on an annualized tax equivalent basis.

Net Income

Net income for the nine months ended September 30, 2022, amounted to $30.4 million, a decrease of $913 thousand, or 3%, compared to the prior year period.

•The decrease in net income was attributable primarily to increases in the provision for credit losses of $3.2 million and non-interest expense of $4.5 million, partially offset by increases in net interest income of $3.7 million and non-interest income of $2.1 million.

Net Interest Income

Net interest income for the nine months ended September 30, 2022, amounted to $109.6 million, an increase of $3.7 million, or 4%, compared to the nine months ended September 30, 2021.

•The increase in net interest income was due largely to an increases in loan income, excluding PPP (non-GAAP), of $11.4 million, investment security income of $3.4 million, other interest-earning asset income of $1.8 million, and a decrease in interest expense of $760 thousand, partially offset by a decrease PPP income of $14.0 million.

•PPP income amounted to $2.5 million for the nine months ended September 30, 2022, compared to $16.5 million for the nine months ended September 30, 2021. PPP loans outstanding amounted to $2.7 million at September 30, 2022,

41

compared to $148.2 million at September 30, 2021, due to the continued forgiveness of PPP loans by the SBA during the period.

Net Interest Margin

Net interest margin was 3.45% and 3.48% for the nine-month periods ended September 30, 2022 and September 30, 2021, respectively.

Key items impacting margin for the nine months ended September 30, 2022, compared to the prior year period included:

•Average interest-earning deposits with banks decreased $166.1 million, or 34%, while the yield increased 94 basis points. The decrease in average balance resulted primarily from the funding of growth in the Company's investment and core loan portfolios, partially offset by funds received from the forgiveness of PPP loans by the SBA. The increase in yield reflected the 300 basis point increase in the federal funds rate during the nine months ended September 30, 2022.

•Average investment securities at fair value increased $341.1 million, or 55%, while the tax-equivalent yield decreased 41 basis points. The changes in average balance and yield resulted primarily from investment security purchases in the second half of 2021 when market interest rates were lower than the portfolio yield at that time.

•Average loans increased $4.0 million, while the tax-equivalent yield decreased 12 basis points.

◦Average PPP loans outstanding decreased $335.4 million, or 93%, due to the continued forgiveness of PPP loans by the SBA during the period.

◦Average core loans (non-GAAP) increased $339.4 million, or 13%, and the tax-equivalent yield increased 2 basis points. The increase in average balance resulted primarily from growth in the commercial and residential real estate portfolios. Core loan yields in 2022 have been positively impacted by increases in the prime lending rate of 300 basis points, mostly offset by significant fixed-rate originations when market rates were lower.

•Average total deposits increased $176.6 million, or 5%, while the yield decreased 3 basis points.

◦Average non-interest checking balances increased $109.6 million, or 8%.

◦Average higher-costing brokered deposits decreased $61.0 million, or 100%.

•Adjusted net interest margin (non-GAAP), which excludes PPP loans and interest-earning deposits with banks, amounted to 3.58% and 3.69%, respectively. The decrease reflected primarily net growth in fixed rate investment securities and loans when market interest rates were lower, partially offset by recent yield increases on floating rate loans and from a decrease in the cost of funds.

Interest-rate risk is reviewed in detail in Item 3, "Quantitative and Qualitative Disclosures About Market Risk," below.

Rate / Volume Analysis

The following table sets forth, on a tax-equivalent basis, the extent to which changes in interest rates and changes in the average balances of interest-earning assets and interest-bearing liabilities have affected interest income and expense during the nine months ended September 30, 2022, compared to the nine months ended September 30, 2021. For each category of interest-earning assets and interest-bearing liabilities, information is provided on changes attributable to: (i) volume (change in average portfolio balance multiplied by prior year average rate); and (ii) interest rate (change in average interest rate multiplied by prior year average balance). Changes attributable to the combined impact of volume and rate have been allocated proportionately based on absolute value to the changes due to volume and the changes due to rate.

Provision for Credit Losses

The provision for credit losses for the nine months ended September 30, 2022, amounted to $3.9 million, an increase of $3.2 million, compared to the nine months ended September 30, 2021.

•The provision for the nine months ended September 30, 2022, consisted of $3.6 million for growth of loans outstanding, partially offset by a reduction of $359 thousand in reserves on unfunded commitments (included in other liabilities).

•Most of the provision for the nine months ended September 30, 2022, related to the Company's strong loan growth during the nine months ended September 30, 2022, and to a lesser extent, a deterioration in the economic forecast due to the rising interest rate environment and persistent high inflation levels, partially offset by improved credit quality.

The provision for credit losses is a significant factor in the Company's operating results. For further discussion regarding the provision for credit losses and management's assessment of the adequacy of the ACL see "Asset Quality," and "ACL for Loans" under "Financial Condition" in this Item 2, below.

Non-Interest Income

Non-interest income for the nine months ended September 30, 2022, amounted to $14.3 million, an increase of $2.1 million, or 17%, compared to the nine months ended September 30, 2021.

•Non-interest income in the prior year period included a loss on the termination of swaps used in hedging activities of $1.8 million. Excluding this item, non-interest income increased $274 thousand, or 2%, resulting primarily from increases in net gains on sales of debt securities of $934 thousand and deposit and interchange fees of $777 thousand, partially offset by a decrease in gains on sales of loans of $765 thousand and an increase in losses on equity securities of $842 thousand.

Non-Interest Expense

Non-interest expense for the nine months ended September 30, 2022, amounted to $80.1 million, an increase of $4.5 million, or 6%, compared to the nine months ended September 30, 2021.

•The increase in non-interest expense over the respective periods resulted primarily from an increase in salaries and employee benefits of $4.1 million, or 8%. The increase in salaries and employee benefit expense during the nine months ended September 30, 2022, included an increase of $1.2 million in performance-based incentive accruals. Excluding this cost, the increase in salaries and benefits expense amounted to $2.9 million, or 7%, compared to the prior year period.

•Non-interest expense in the prior year period included a loss on extinguishment of subordinated debt of $713 thousand.

Income Taxes

The effective tax rate for the nine months ended September 30, 2022, was 23.6%, compared to 24.8% for the nine months ended September 30, 2021. Tax expense for the nine months ended September 30, 2022, benefited from a lower effective tax rate compared to the prior year period due to increases in tax-exempt income, lower-taxed income at Bank's security corporation subsidiaries and discrete tax benefits related to stock-based compensation transactions.

Financial Condition

Total assets amounted to $4.53 billion at September 30, 2022, compared to $4.45 billion at December 31, 2021, an increase of $82.0 million, or 2%. The increase was driven by an increase in core loans (non-GAAP) of $257.5 million, partially offset by decreases in interest-earning deposits with banks of $34.7 million, investments securities at fair value of $127.2 million, and PPP loans outstanding of $68.8 million. The balance sheet composition and changes since December 31, 2021 are discussed below.

Cash and cash equivalents

Cash and cash equivalents at September 30, 2022 decreased $22.9 million since December 31, 2021. At September 30, 2022 and December 31, 2021, cash and cash equivalents amounted to 9% and 10% of total assets, respectively. The decrease in cash and cash equivalents since December 31, 2021 was related primarily to funding core loan growth (non-GAAP), partially offset by funds received from the SBA for forgiveness of PPP loans during the nine months ended September 30, 2022.

45

Investments

At September 30, 2022, the fair value of the investment portfolio amounted to $831.0 million, a decrease of $127.2 million, or 13%, since December 31, 2021. The investment portfolio at fair value represented 18% and 22% of total assets at September 30, 2022 and December 31, 2021, respectively. The change resulted primarily from a decrease in the fair value of the Company's investment portfolio of $129.6 million, during the nine months ended September 30, 2022, caused primarily by significant increases in market interest rates over the respective periods. As of September 30, 2022 and December 31, 2021, the Company's investment portfolio was comprised primarily of debt securities, classified as available-for-sale, with a small portion of the portfolio invested in equity securities.

During the nine months ended September 30, 2022, the Company purchased $101.5 million in debt securities, had principal pay downs, calls and maturities totaling $68.1 million, and sold debt securities with an amortized cost of approximately $31.7 million realizing net gains on sales of $1.1 million.

Net unrealized losses on the debt securities portfolio amounted to $123.7 million at September 30, 2022, compared to net unrealized gains of $5.9 million at December 31, 2021 and $17.5 million at September 30, 2021. The Company attributes the change in net unrealized gains (losses) compared to December 31, 2021 to the significant increases in market interest rates during the respective periods.

The mix of investment securities remained relatively unchanged at September 30, 2022 compared to December 31, 2021. The effective duration of the debt securities portfolio at September 30, 2022 was approximately 5.1 years compared to 4.9 years at December 31, 2021.

Loans

As of September 30, 2022, total loans increased $188.7 million, or 6%, compared to December 31, 2021. The increase in total loans as of September 30, 2022 compared to December 31, 2021 was due primarily to net core loan growth (non-GAAP) of $257.5 million, partially offset by a decrease in PPP loans outstanding of $68.8 million due to forgiveness from the SBA. The mix of loans within the Company's loan portfolio remained relatively unchanged with commercial loans amounting to 87% of total loans at September 30, 2022, compared to 88% at December 31, 2021.

The following table sets forth the loan balances by loan portfolio segment at the dates indicated and the percentage of each segment to total loans:

As of, or for the nine months ended September 30, 2022,

•Growth in the commercial real estate portfolio has been strong over the last twelve months resulting in a slight increase in commercial real estate loans as a percentage of total loans, relative to the commercial and industrial and commercial construction portfolios.

46

•Commercial real estate loans increased $205.6 million, or 12%, compared to December 31, 2021. The increase resulted from strong customer demand.

•Commercial and industrial loans increased by $1.3 million, or 0%, compared to December 31, 2021.

•Commercial construction loans decreased by $14.4 million, or 4%, since December 31, 2021. The decrease was driven by relatively high payoff volume during the period.

•PPP loan forgiveness by the SBA amounted to $71.1 million.

•Total retail loans increased by $65.0 million, or 19%, since December 31, 2021. The increase resulted from the Company retaining more residential mortgages on its balance sheet.

At September 30, 2022, commercial loan balances participated out to various banks amounted to $59.0 million, compared to $66.7 million at December 31, 2021. These balances participated out to other institutions are not carried as assets on the Company's financial statements. Commercial loans originated by other banks in which the Company is a participating institution are carried at the pro-rata share of ownership and amounted to $90.8 million and $62.6 million at September 30, 2022 and December 31, 2021, respectively. See Note 3, "Loans," to the Company's unaudited consolidated interim financial statements contained in Item 1 of this Form 10-Q above for information on loans serviced for others and loans pledged as collateral.

Asset Quality

The following table sets forth information regarding non-performing assets, TDR loans and delinquent loans 60-89 days past due as to interest or principal, held by the Company at the dates indicated:

Allowance for credit losses for loans to total loans	1.65		%	1.63		%	1.66		%

The decrease in non-performing loans at September 30, 2022, compared to December 31, 2021, was due primarily to two commercial relationships, amounting to $17.9 million, which were upgraded and restored to accrual status during the second quarter of 2022 due to improved financial strength and consistent payment history, as well as pay-downs and payoffs on several commercial relationships.

As of September 30, 2022, the ACL for loans to total loans ratio was 1.65% at September 30, 2022, compared to 1.63% at December 31, 2021.

47

The majority of non-accrual loans were also carried as adversely classified during the periods presented. At September 30, 2022 and December 31, 2021, the Company had adversely classified loans (loans carrying "special mention," "substandard," "doubtful" or "loss" classifications) amounting to $48.7 million and $61.0 million, respectively. Adversely classified loans that were performing but possessed potential weakness and, as a result, could ultimately become non-performing loans amounted to $43.0 million at September 30, 2022 and $34.5 million at December 31, 2021. The remaining balances of adversely classified loans which were non-accrual loans, amounted to $5.7 million at September 30, 2022 and $26.5 million at December 31, 2021.

Total individually evaluated collateral dependent loans amounted to $26.4 million and $34.6 million at September 30, 2022 and December 31, 2021, respectively. Total accruing collateral dependent loans amounted to $21.0 million and $8.4 million at September 30, 2022 and December 31, 2021, respectively, while non-accrual collateral dependent loans amounted to $5.4 million and $26.2 million as of September 30, 2022 and December 31, 2021, respectively.

In management's opinion, the majority of collateral dependent loan balances at September 30, 2022 and December 31, 2021 were supported by the net realizable value of the underlying collateral. Based on management's collateral assessment at September 30, 2022, collateral dependent loans totaling $25.0 million required no specific reserves while collateral dependent loans totaling $1.4 million required specific reserves of $275 thousand. At December 31, 2021, collateral dependent loans totaling $18.4 million required no specific reserves while collateral dependent loans totaling $16.2 million required specific reserves of $1.0 million.

Total TDR loans as of September 30, 2022 and December 31, 2021, were $8.6 million and $16.4 million, respectively. TDR loans on accrual status amounted to $5.8 million and $8.6 million at September 30, 2022 and December 31, 2021, respectively. TDR loans included in non-accrual loans amounted to $2.8 million at September 30, 2022 and $7.8 million at December 31, 2021. The Company continues to work with customers and enters into loan modifications (which may or may not be TDRs) to the extent deemed to be necessary or appropriate while attempting to achieve the best mutual outcome given the individual financial circumstances and prospects of the borrower.

ACL for Loans

There have been no material changes to the Company's underwriting practices or credit risk management system used to estimate credit loss exposure as described in the 2021 Annual Report on Form 10-K. See Note 4, "ACL for Loans," to the Company's audited consolidated financial statements contained the 2021 Annual Report on Form 10-K. 

See Note 4, "ACL for Loans," to the Company's unaudited consolidated interim financial statements, contained in Item 1 in this Form 10-Q, for further information regarding credit quality and the allowance for credit losses and the Company's methodology under CECL.

While management uses available information and judgment to estimate credit losses on loans, future additions to the ACL may be necessary. In addition, various regulatory agencies, as an integral part of their examination process, periodically review the Company's ACL for loans. Such agencies may require the Company to recognize additions to the ACL based on judgments different from those of management.

See Note 4, "ACL for Loans," to the Company's unaudited consolidated interim financial statements, contained in Item 1 in this Form 10-Q, for further information regarding the ACL for loans and credit quality.

Reserve for unfunded commitments

The reserve for unfunded commitments is classified within "Other liabilities" on the Company's Consolidated Balance Sheets. The estimate of credit loss incorporates assumptions for both the likelihood and amount of funding over the estimated life of the commitments, including adjustments for current conditions and reasonable and supportable forecasts. Management periodically reviews and updates its assumptions for estimated funding rates.

The Company's reserve for unfunded commitments amounted to $4.1 million as of September 30, 2022 and $3.7 million at December 31, 2021. The provision for unfunded commitments amounted to $440 thousand compared to $681 thousand for the three months ended September 30, 2022 and September 30, 2021, respectively. The provision for unfunded commitments amounted to $359 thousand compared to $538 thousand for the nine months ended September 30, 2022 and September 30, 2021, respectively.

Management believes that the Company's ACL for loans and the reserve for unfunded commitments were adequate as of September 30, 2022.

Deposits

As of September 30, 2022, customer deposits increased $157.8 million, or 4%, since December 31, 2021 with the largest growth occurring in non-interest checking accounts of $76.8 million, or 6%.

The following table sets forth the deposit balances by certain categories at the dates indicated and the percentage of each category to total deposits:

	September 30, 2022				December 31, 2021				September 30, 2021
(Dollars in thousands)	Amount		Percent		Amount		Percent		Amount		Percent
Checking	$	2,160,578	52	%	$	2,107,845	53	%	$	2,118,344	53	%
Money markets and savings	1,747,421		42	%	1,665,945		42	%	1,638,259		41	%
Certificates of deposit ("CDs")	230,039		6	%	206,449		5	%	214,333		6	%
Deposits	$	4,138,038	100	%	$	3,980,239	100	%	$	3,970,936	100	%

Borrowed Funds

The Company had borrowed funds outstanding of $2.9 million and $5.5 million at September 30, 2022 and December 31, 2021, respectively, all of which were FHLB advances related to specific lending projects under the FHLB's community development and affordable housing programs.

Subordinated Debt

The Company had outstanding subordinated debt, net of deferred issuance costs, of $59.1 million at September 30, 2022 compared to $59.0 million at December 31, 2021.

See also Note 7, "Borrowed Funds and Subordinated Debt," to the Company's unaudited consolidated interim financial statements contained in Item 1 above in this Form 10-Q, for further information regarding the Company's subordinated debt.

Shareholders' Equity

Total shareholders' equity amounted to $272.2 million at September 30, 2022, compared to $346.9 million at December 31, 2021, a decrease of $74.7 million, or 22%. The change was attributable primarily to a decrease in AOCI of $100.3 million since December 31, 2021, partially offset by an increase in retained earnings of $23.0 million over the same period. The change in AOCI resulted from a decrease in the fair value of debt securities, which is attributed to the significant increase in market interest rates during the period. The Company classifies all debt securities as available-for-sale and at September 30, 2022 anticipates they will mature or be called at par value.

The Company's reported book value per common share and return on average shareholders' equity ratios were impacted by the change in AOCI as follows:

•Book value per common share was $22.44 at September 30, 2022, compared to $28.82 at December 31, 2021, a decrease of 22%. Excluding AOCI (non-GAAP), book value per common share was $30.33 at September 30, 2022 and $28.43 at December 31, 2021, an increase of 7%.

•Return on average shareholders' equity was 16.47% and 12.56% for the quarters ended September 30, 2022, and December 31, 2021, respectively. Return on average shareholders' equity, excluding AOCI (non-GAAP), was 12.95% and 12.69% for the quarters ended September 30, 2022, and December 31, 2021, respectively.

For the nine months ended September 30, 2022 and September 30, 2021, the Company declared cash dividends of $7.4 million and $6.7 million, respectively, and shareholders utilized the dividend reinvestment portion of the Company's dividend reinvestment and direct stock purchase plan to purchase aggregate shares of the Company's common stock amounting to 30,821 shares and 28,499 shares, totaling $1.1 million and $938 thousand, respectively.

On October 18, 2022, the Company announced a quarterly dividend of $0.205 per share to be paid on December 1, 2022 to shareholders of record as of November 10, 2022.

50

Derivatives and Hedging

The Company had no derivative fair value or cash flow hedges at either September 30, 2022 or December 31, 2021.

The notional value of interest-rate swaps with customers decreased to $7.8 million at September 30, 2022 from $36.3 million at December 31, 2021 due to customer pay-offs. The fair value of assets and corresponding liabilities associated with these swaps and carried on the Company's Consolidated Balance Sheets was $836 thousand at September 30, 2022 compared to $528 thousand at December 31, 2021.

For further information on the Company's derivatives and hedging activities see Note 8, "Derivatives and Hedging Activities," to the Company's unaudited consolidated interim financial statements contained in Item 1 above in this Form 10-Q.

Liquidity

Liquidity is the ability to meet cash needs arising from, among other things, fluctuations in loans, investments, deposits and

borrowings. Liquidity management is the coordination of activities so that cash needs are anticipated and met readily and

efficiently. The Company's liquidity is maintained by projecting cash needs, balancing maturing assets with maturing liabilities, monitoring various liquidity ratios, monitoring deposit flows, maintaining cash flow within the investment portfolio, and maintaining wholesale funding resources.

The Company's wholesale funding sources included primarily borrowing capacity at the FHLB and brokered deposits. In addition, the Company's secondary funding sources include uncommitted overnight federal fund purchase arrangements with correspondent banks, access to the FRB Discount Window. At September 30, 2022, the Bank had the capacity to borrow additional funds from the FHLB and FRB Discount Window of up to approximately $765.0 million and $360.0 million, respectively.

Management believes that the Company has adequate liquidity to meet its obligations. However, if general economic conditions, the pandemic, changes in market interest rates, the persistence of the inflationary environment in the United States and our market areas, or other events, cause these sources of external funding to become restricted or are eliminated, the Company may not be able to raise adequate funds or may incur substantially higher funding costs or operating restrictions in order to raise the necessary funds to support the Company's operations and growth.

Capital Resources

The principal cash requirement of the Company is the payment of interest on subordinated debt and the payment of dividends on our common stock. The Company's Board of Directors approves cash dividends on a quarterly basis after careful analysis and consideration of various factors, including our capital position, economic conditions, growth rates, earnings performance and projections as well as strategic initiatives and related capital requirements.

The Company's primary source of cash is dividends paid by the Bank, which are limited to the Bank’s net income for the current year plus its retained net income for the prior two years.

The Company's total capital and tier 1 capital to risk weighted assets amounted to 13.49% and 10.52%, respectively, at September 30, 2022, compared to 13.73% and 10.62%, respectively, at December 31, 2021. The decrease in each ratio was due primarily to strong core loan growth (non-GAAP) over the respective periods, which required higher capital reserves than interest-earning deposits with banks.

Tier 1 capital to average assets amounted to 7.89% at September 30, 2022, compared to 7.56% at December 31, 2021. The increase was driven primarily by the increase in retained earnings noted above, partially offset by an increase in average assets.

For further information about the Company's capital, see Note 9 "Regulatory Capital Requirements," to the Company's unaudited consolidated interim financial statements contained in Item 1 of this Form 10-Q.

Wealth Management

Wealth assets under management and wealth assets under administration are not carried as assets on the Company's consolidated balance sheets. The Company provides a wide range of wealth management and wealth services, including investment management, brokerage, annuities, trust, and 401(k) administration.

51

Wealth assets under management and wealth assets under administration amounted to $835.7 million and $186.0 million, respectively, at September 30, 2022, representing decreases of $205.7 million, or 20%, and $71.9 million, or 28%, respectively, compared to December 31, 2021. The decreases in wealth assets under management and administration were attributable primarily to declines in market values during the nine months ended September 30, 2022.

Item 3 -Quantitative and Qualitative Disclosures About Market Risk

Interest Margin Sensitivity Analysis

Refer to Part II, Item 7A, "Quantitative and Qualitative Disclosures About Market Risk" of the Company's 2021 Annual Report on Form 10-K for further information on the Company's net interest income and net interest margin sensitivity under different interest rate and yield curve scenarios as well as different asset and liability mix scenarios.

The net interest income simulation model assumes a static balance sheet over 24 months. In the 200 and 400 basis point rising rate scenarios below, net interest income is projected to increase in the first 24 months primarily due to the elevated balance of net short-term liquidity that reprices immediately. In the 200 basis point declining interest rate scenario, net interest income is projected to decrease as funding costs are at low levels and do not decline as significantly as asset yields.

At September 30, 2022, the Company's net interest income sensitivity decreased compared to December 31, 2021, resulting primarily from a decrease in net liquidity and growth in the Company’s fixed rate commercial real estate and to a lesser extent, growth in residential mortgage portfolios. The increase in residential mortgages was from the Company retaining more production on the balance sheet instead of selling into the secondary market.

In the declining interest rate scenario, the percent change in net interest income was relatively consistent to results at December 31, 2021 primarily due to the aforementioned decrease in interest rate sensitivity from the decline in liquidity and the increase in fixed rate loans, mostly offset by an increase in interest rate sensitivity caused by higher yields on short term investments.

Net short-term liquidity, which is included in the table below is defined as interest-earning deposits in banks less short-term wholesale borrowings consisting of brokered deposits and FHLB borrowings. The balance is generally considered to be high at September 30, 2022 and December 31, 2021 and resulted in large part to funds received from the forgiveness of PPP loans offset by core loan growth.

The following table summarizes the results from the Company's net interest income simulation model and compares the percent change in net interest income to the rates unchanged scenario, for a 24-month period at September 30, 2022 and December 31, 2021.

(Dollars in thousands, except for percentage data)	September 30, 2022			December 31, 2021
Net liquidity	$	365,409		$	397,525
Changes in interest rates	Percentage Change			Percentage Change
Rates Rise 400 Basis Points	3.98		%	9.73		%
Rates Rise 200 Basis Points	1.94		%	5.37		%
Rates Unchanged	—		%	—		%
Rates Decline 100 Basis Points	(8.60)		%	(4.95)		%

The results in the table above are subject to various assumptions as reported in Part II, Item 7A, “Quantitative and Qualitative Disclosures About Market Risk” of the Company's 2021 Annual Report on Form 10-K. Refer to heading "Results of Operations" contained within Item 2, "Management's Discussion and Analysis of Financial Condition and Results of Operations" of this Form 10-Q for further discussion of margin.

Item 4 -Controls and Procedures

Evaluation of Disclosure Controls and Procedures

The Company maintains a set of disclosure controls and procedures and internal controls designed to ensure that the information required to be disclosed in reports that it files or furnishes to the SEC under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), is recorded, processed, summarized, and reported within the time periods specified in the SEC's rules and forms.

The Company carried out an evaluation as of the end of the period covered by this Form 10-Q under the supervision and with the participation of the Company's management, including its principal executive officer and principal financial officer, of the effectiveness of the design and operation of the Company's disclosure controls and procedures pursuant to Exchange Act Rule 13a-15(b). Based upon that evaluation, the Company's principal executive officer and principal financial officer concluded that the Company's disclosure controls and procedures are effective as of September 30, 2022.

Changes in Internal Control over Financial Reporting

There have been no significant changes in the Company's internal control over financial reporting that occurred during the Company's most recent fiscal quarter (i.e., the three months ended September 30, 2022) that materially affected, or is reasonably likely to materially affect, the Company's internal control over financial reporting.

53

PART II - OTHER INFORMATION

Item 1 -Legal Proceedings

There are no material pending legal proceedings to which the Company or its subsidiaries are a party or to which any of its property is subject, other than ordinary routine litigation incidental to the business of the Company. Management does not believe resolution of any present litigation will have a material adverse effect on the business, consolidated financial condition or results of operations of the Company.

Item 1A -Risk Factors

Except as provided in the risk factor below, management believes that there have been no material changes in the Company's risk factors as reported in the 2021 Annual Report on Form 10-K.

If the United States or the markets in which we operate encounter sustained economic stress or recession, or if long-term consequences or lagging effects of the pandemic are experienced by our customers and businesses, many of the risk factors identified in the Company's 2021 Annual Report on Form 10-K could become heightened and such effects could have a material adverse impact on the Company in a number of ways related to credit, collateral, customer demand, funding, operations and interest-rate risk.
