(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, 2022 audited consolidated financial statements and notes thereto contained in the Annual Report on Form 10-K of Enterprise Bancorp, Inc. (the "Company," "Enterprise," "we," or "our") for the year ended December 31, 2022 (the "2022 Annual Report on Form 10-K") as filed with the Securities and Exchange Commission (the "SEC") on March 8, 2023. The Company has not materially changed its significant accounting policies from those disclosed in its 2022 Annual Report on Form 10-K. See Item (d), "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. In February 2023, the Bank organized the EBTC NMTC Investment Fund - CHC, LLC (the "NMTC Investment Fund") under the laws of the State of Delaware, in conjunction with the Banks investment in a qualifying New Market Tax Credit ("NMTC") project. The NMTC Investment Fund is the Company's only unconsolidated Variable Interest Entity ("VIE"). 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 March 31, 2023 (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. 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 2022 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, available for sale securities and 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 2022 Annual Report on Form 10-K for accounting policies related to these significant estimates.

In March 2023, the Bank made an equity contribution to the NMTC Investment Fund a newly formed Limited Liability Company in order to invest in NMTC, a program, which is administered by the U.S. Department of the Treasury's Community Development Financial Institutions Fund and allocated to Community Development Entities ("CDE").

The NMTC program provides federal tax incentives for investments in distressed communities and promotes economic improvements through the development of successful businesses in these communities. The NMTCs are available to investors

over a seven-year period and are subject to recapture if certain events occur during such period. The Bank invested $3.7 million in the Investment Fund and anticipates receiving $4.8 million of federal tax credits over the next seven years (5% in each of the first three years, and 6% in each of the next four years). The underlying project is structured through a qualified CDE, which in turn has made loans to a qualified active low-income business. The Bank has no unfunded commitments associated with its NMTC investment. The Company has elected to account for the tax equity investment, using the proportional amortization method. Under this method the NMTC Investment Fund is not consolidated with the Company and instead, the initial cost of the investment is amortized in proportion to the amount of tax credits and other tax benefits received over the allotment period. The investment is carried within the line "Prepaid expenses and other assets" on the Company's Consolidated Balance Sheet and the investment amortization expense and tax credits are presented on a net basis within the line "Provision for income taxes" on the Company's Consolidated Statements of Income. During the three months ended March 31, 2023, the related amortization expense and tax credits amounted to $44 thousand and $153 thousand, respectively.

(d) Recent Accounting Pronouncements

Accounting pronouncements adopted by the Company

In March 2023, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2023-02, "Investments—Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method." ASU 2023-02 permits reporting entities to elect to account for their tax equity investments, regardless of the tax credit program from which the income tax credits are received, using the proportional amortization method if certain conditions are met. The election can be made for each individual qualifying tax credit investment. Under the proportional amortization method, the initial cost of an investment is amortized in proportion to the amount of tax credits and other tax benefits received, with the amortization and tax credits recognized as a component of income tax expense. To qualify for the proportional amortization method, all of the following conditions must be met: (1) It is probable that the income tax credits allocated to the tax equity investor will be available; (2) The tax equity investor does not have the ability to exercise significant influence over the operating and financial policies of the underlying project; (3) Substantially all of the projected benefits are from income tax credits and other income tax benefits; (4) The tax equity investor's projected yield based solely on the cash flows from the income tax credits and other income tax benefits is positive; and (5) The tax equity investor is a limited liability investor in the limited liability entity for both legal and tax purposes, and the tax equity investor's liability is limited to its capital investment. Under the proportional amortization method, the investment shall be tested for impairment when events or changes in circumstances indicate that it is more likely than not that the carrying amount of the investment will not be realized. An impairment loss shall be measured as the amount by which the carrying amount of an investment exceeds its fair value. A previously recognized impairment loss shall not be reversed. ASU 2023-02 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2023. The Company has elected to early adopt ASU 2022-01 effective on January 1, 2023, applying the new guidance to a new investment in NMTC made in the first quarter of 2023, and the adoption did not have a significant impact on the financial statements.

In March 2022, the FASB issued 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 2022-01 renames that method the "portfolio layer" method and addresses feedback from stakeholders regarding its application. The Company adopted ASU 2022-01 effective on January 1, 2023 and the adoption did not have a significant impact on the 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. The Company adopted ASU 2022-02 effective on January 1, 2023, prospectively, and the adoption did not have a significant impact on the financial statements.

(e) Subsequent Events

The Company has evaluated subsequent events and transactions from March 31, 2023 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 March 31, 2023, 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 last twelve months. Management concluded that no ACL for available-for-sale securities was necessary as of March 31, 2023 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 $4.8 million and $4.0 million at March 31, 2023 and December 31, 2022, respectively.

The contractual maturity distribution at March 31, 2023 of debt securities was as follows:


(Dollars in thousands)	Amortized Cost		Fair Value
Due in one year or less	$	43,577	$	42,648
Due after one, but within five years	137,025		133,624

Total debt securities	$	923,485	$	825,520

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 $162.1 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 $814.7 million and $804.2 million at March 31, 2023 and December 31, 2022, respectively.

Loan modifications to borrowers experiencing financial difficulty

Effective on January 1, 2023, the Company adopted ASU 2022-02, "Financial Instruments—Credit Losses (Topic 326), Troubled Debt Restructurings ("TDR") and Vintage Disclosures," which eliminated the accounting guidance for TDRs and enhanced the disclosure requirements for loan restructurings made with borrowers experiencing financial difficulty. The adoption did not have a significant impact on the financial statements.

The Company continues to work with loan customers and may enter into loan modifications 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. An assessment of whether a borrower is experiencing financial difficulty is made on the date of the modification. Modifications made to borrowers experiencing financial difficulty may be concessions in the form of principal forgiveness, interest rate reductions, payment deferrals of principal, interest or both, or term extensions, or some combination thereof. When a debt has been previously modified, the Company considers the cumulative effect of modifications made within the prior twelve-month period before the current modification, when determining whether a delay in payment resulting from the current modification is insignificant, or not.

The following table presents the amortized cost basis of loan modifications made to borrowers experiencing financial difficulty by type of concession granted during the period indicated:

During the three months ended March 31, 2023, there were no subsequent defaults on loans that had been modified within the preceding twelve months for borrowers experiencing financial difficulty, and at March 31, 2023, additional funding commitments to borrowers experiencing financial difficulty who were party to a loan modification were immaterial.

Prior-period troubled debt restructuring disclosures

Prior to adopting the new accounting standard on loan modifications, the Company accounted for modifications of loans to borrowers experiencing financial difficulty as TDRs, when the modification resulted in a concession and specific reserves were charged to the ACL if necessary for the amount of estimated credit loss. The following discussion reflects loans that were considered TDRs prior to January 1, 2023. For further information on the Company's TDR accounting policies, see Note 1, "Summary of Significant Accounting Policies," to the Company's audited consolidated financial statements contained in the 2022 Annual Report on Form 10-K.

At March 31, 2022, additional funding commitments for TDR loans were immaterial.

The following table presents the number and balance of loans modified as TDRs, by portfolio classification, during the period indicated:



		Three months ended

__________________________________________

(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 March 31, 2023 or December 31, 2022.

Interest-rate Contracts

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 four interest-rate swaps outstanding at March 31, 2023 and December 31, 2022. As a result of this offsetting relationship, there were no net gains or losses recognized in income on back-to-back swaps during the three months ended March 31, 2023 or March 31, 2022.

Interest-rate swaps with counterparties are subject to master netting agreements, while interest-rate swaps with customers are not. At March 31, 2023 and December 31, 2022, all back-to-back swaps with the counterparty were in asset positions, therefore there was no netting reflected in the Company's Consolidated Balance Sheets as of the respective dates.

Risk Participation Agreements

The Company enters into risk participation agreements ("RPA") for which the Company has assumed credit risk for customers' performance under interest-rate swap agreements related to the customers' commercial loan and receives fee income commensurate with the risk assumed. The RPA and the customers' loan are secured by the same collateral.

Credit Risk

The Company had one active interest-rate swap institutional counterparty that was rated A and A2 by Standard & Poor's and Moody's, respectively, at March 31, 2023. 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


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

Company's Consolidated Balance Sheets. If the Company posts collateral, the restricted cash is carried on the Company's Consolidated Balance Sheets. At March 31, 2023, the Company had no credit risk exposure relating to interest-rate swaps with counterparties and posted no cash collateral. At December 31, 2022, the Company had credit risk exposure relating to interest-rate swaps with counterparties of $708 thousand and cash collateral posted by counterparties amounted to $20 thousand.

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, 2022. As of March 31, 2023, the fair value of derivatives related to these agreements was at a net liability position of $10 thousand, which excludes any adjustment for nonperformance risk. The Company has minimum collateral posting thresholds with certain of its derivative counterparties and as of March 31, 2023, has not posted collateral related to these agreements.

Other Derivative Related Activity

At both March 31, 2023 and December 31, 2022, the Company had one participation loan for which the originating bank utilizes a back-to-back interest-rate swap structure and the Company has assumed a contingent liability commensurate with its participation percentage in the loan. At March 31, 2023, 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 March 31, 2023 and December 31, 2022, 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

As of March 31, 2023 and December 31, 2022, 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 the FDIC and the Basel III capital guidelines.

(1)Before application of the capital conservation buffer of 2.50% as of March 31, 2023, and December 31, 2022. 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 March 31, 2023. At March 31, 2023, the capital conservation buffer amounted to $89.7 million for both the Company and the Bank.

There were 34,164 and 34,210 stock options outstanding for the three months ended March 31, 2023 and March 31, 2022, respectively, that were determined to be anti-dilutive and therefore excluded from the calculation of dilutive shares for those periods. These stock options, which were not dilutive, may potentially dilute earnings per share in the future.

Unvested participating restricted awards amounted to 135,216 shares and 106,658 shares as of March 31, 2023 and December 31, 2022, 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 of derivative assets and liabilities, which are comprised of back-to-back swaps and risk participation agreements, 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.

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 $371 thousand at March 31, 2023, compared to $298 thousand at December 31, 2022.

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 March 31, 2023 and December 31, 2022:

Overview

Executive Summary

The Company operates with a strategic, long-term outlook, which is focused on organic growth and supports such growth by continually investing in our people, products, services, technology, and our branch network.

Our financial condition at March 31, 2023, as well as the results of operations for the three months ended March 31, 2023, have been impacted by significant increases in market interest-rates due to the 475 basis point increase in the prime lending rate since March 2022 by the Federal Reserve Board in response to the persistent inflationary environment in the United States. The impact is addressed as applicable throughout this Item 7, "Management's Discussion and Analysis of Financial Condition and Results of Operations."

Net income for the three months ended March 31, 2023, amounted to $10.8 million, or $0.88 per diluted common share, compared to $10.3 million, or $0.85 per diluted common share, for the three months ended March 31, 2022. The increase was attributable primarily to an increase in net interest income of $5.9 million, partially offset by increases in the provision for credit losses of $2.2 million and non-interest expense of $2.3 million and a decrease in non-interest income of $838 thousand.

Total assets amounted to $4.44 billion at both March 31, 2023 and December 31, 2022. Investment securities at fair value increased $10.5 million, or 1%, compared to December 31, 2022, primarily from an increase in the fair value of the debt securities portfolio of $26.2 million due to lower market interest rates, partially offset by principal pay-downs, calls and maturities during the period. Total loans increased $49.6 million, or 1.6% (6% annualized), compared to December 31, 2022, primarily from net growth in the commercial construction portfolio, amounting to $32.7 million.

The ACL for loans amounted to $55.0 million, or 1.70% of total loans, at March 31, 2023, compared to $52.6 million, or 1.66% of total loans, at December 31, 2022. The reserve for unfunded commitments (included in other liabilities) amounted to $4.7 million at March 31, 2023, compared to $4.3 million at December 31, 2022. The increase in credit loss reserves resulted primarily from a forecasted increase in the probability and severity of a recession in our allowance model, and to a lesser extent, growth in the Company's loan portfolio and off-balance sheet commitments.

During the three months ended March 31, 2023, customer deposits decreased $19.7 million, or 0.5% (2% annualized). The decrease in customer deposits reflected a highly competitive environment in which deposit customers have access to higher yielding money market and treasury alternatives. In addition, customer deposits at March 31, 2023 were positively impacted by the receipt of a large deposit of approximately $60.0 million that management believes may be temporary and resulted from a customer business transaction.

During the three months ended March 31, 2023, shareholders' equity increased $29.1 million, due primarily to a reduction in the accumulated other comprehensive loss ("AOCL") of $20.2 million related to an increase in the fair value of the debt securities portfolio which was driven by lower market interest rates during the period.

Update on Liquidity, Deposit Composition and Funding Capacity

All balances and ratios presented below are at March 31, 2023 unless otherwise indicated.

•The Company reported a favorable overnight and short-term investment balance of $172.9 million, which was reported on the balance sheet as interest-earning deposits with banks.

•Total loans amounted to 80% of total deposits.

•There were no brokered deposits and only $3.2 million in wholesale borrowings outstanding, which related to participation in specific pass-through community development programs under the Federal Home Loan Bank of Boston ("FHLB") and to a lesser extent the New Hampshire Business Finance Authority.

•Core deposits (which are total deposits excluding CDs over $250 thousand) amounted to 96% of total deposits.

•Total checking account balances amounted to 47% of total deposits, including non-interest-bearing deposits, which were 31% of total deposits.

•The Company utilized enhanced Federal Deposit Insurance Corporation ("FDIC") insured products and pledged investment securities as collateral for certain deposits. Uninsured deposits, not collateralized, amounted to 36% of total deposits. The company has significant additional capacity to further utilize enhanced FDIC insured products.

•FHLB and FRB secured borrowing capacity amounted to $1.1 billion. In April 2023, the Company pledged additional collateral to the FHLB and intends to participate in the FRB's Bank Term Funding Program. It is anticipated these

Table of Contents

changes will increase the secured borrowing capacity to approximately $1.4 billion, exclusive of any borrowings outstanding.

•The Company had several brokered deposit relationships (unsecured borrowings) available which could provide approximately $800.0 million in additional funding capacity.

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," of the Company's 2022 Annual Report on Form 10-K, for additional information on the Company's key risk mitigation strategies, and Part I, Item 1A, "Risk Factors," section of the Company's 2022 Annual Report on Form 10-K for numerous factors that could adversely affect the Company's future results of operations and financial condition, and its reputation and business model.

Accounting Policies/Critical Accounting Estimates

As discussed in the Company's 2022 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 2022 Annual Report on Form 10-K.

Recent Accounting Pronouncements

See Note 1, Item (d), "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 March 31, 2023 and March 31, 2022

Unless otherwise indicated, the reported results are for the three months ended March 31, 2023 with the "prior year period," being the three months ended March 31, 2022. Average yields are presented on an annualized tax equivalent basis.

Net Income

Net income for the three months ended March 31, 2023, amounted to $10.8 million, an increase of $481 thousand, or 5%, compared to the three months ended March 31, 2022.

•The increase in net income during the current period was due primarily to an increase in net interest income of $5.9 million, partially offset by increases in the provision for credit losses of $2.2 million and non-interest expense of $2.3 million and a decrease in non-interest income of $838 thousand.

Net Interest Income

Net interest income for the three months ended March 31, 2023, amounted to $40.0 million, an increase of $5.9 million, or 17%, compared to the three months ended March 31, 2022.

•The increase in net interest income during the current period was due largely to increases in loan interest income of $8.9 million and other interest-earning asset income of $2.0 million, partially offset by an increase in deposit interest expense of $5.4 million.

Net Interest Margin

Three months ended – March 31, 2023 compared to March 31, 2022

Tax-equivalent net interest margin ("net interest margin") (non-GAAP) was 3.76% for the three months ended March 31, 2023, compared to 3.28% for the three months ended March 31, 2022.

Net interest margin during the current period compared to the prior year period was impacted by the following factors:

•Average interest-earning deposits with banks decreased $185.1 million, or 49%, while the yield increased 430 basis points. The decrease in average balance resulted primarily from funding loan growth and the increase in yield reflected a significant increase in market interest rates over the last twelve months.

•Average investment securities decreased $9.3 million, or 1%, while the tax-equivalent yield increased 22 basis points.

Table of Contents

•Average loans increased $289.6 million, or 10%, and the tax-equivalent yield increased 73 basis points. The increase in loan yield resulted primarily from an increase in the prime lending rate of 475 basis points over the last twelve months, partially offset by a decrease in Paycheck Protection Program ("PPP") income of $1.5 million, due to the continued forgiveness of PPP loans, over the respective periods.

•Average total deposits increased $62.6 million, or 2%, and the yield increased 55 basis points from increases in market interest rates, a shift in deposit mix to higher-yielding products and competition from bank and non-bank alternatives. The yield increases occurred principally over the last six months.

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 March 31, 2023, compared to the three months ended March 31, 2022. 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 three months ended March 31, 2023, amounted to $2.7 million, an increase of $2.2 million, compared to the three months ended March 31, 2022.

•The provision for credit losses for the three months ended March 31, 2023, consisted of $2.3 million in reserves for loans outstanding and $418 thousand in reserves for unfunded commitments (included in other liabilities).

•The increase in the provision for credit losses resulted primarily from a forecasted increase in the probability and severity of a recession in our allowance model and, to a lesser extent, growth in the Company's loan portfolio and off-balance sheet commitments.

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 for loans 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 March 31, 2023, amounted to $4.8 million, a decrease of $838 thousand, or 15%, compared to the three months ended March 31, 2022.

•Non-interest income in the prior year period included net gains on sales of debt securities of $1.1 million. Excluding this item, non-interest income increased $223 thousand, or 5%.

•The change resulted primarily from increases in deposit and interchange fees of $246 thousand and swap fee income of $313 thousand, partially offset by a decrease in insurance commission income of $147 thousand. The latter two items were recorded in other income.

Non-Interest Expense

Non-interest expense for the three months ended March 31, 2023, amounted to $28.0 million, an increase of $2.3 million, or 9%, compared to the three months ended March 31, 2022. The increase resulted primarily from an increase in salaries and employee benefits of $1.7 million, primarily to support the Company's strategic growth initiatives.

Income Taxes

The effective tax rate for the three months ended March 31, 2023, was 22.8%, compared to 22.9% for the three months ended March 31, 2022.

Financial Condition

Total assets amounted to $4.44 billion at both March 31, 2023 and December 31, 2022, representing an increase of $3.6 million. The balance sheet composition and changes since December 31, 2022, are discussed below.

Cash and cash equivalents

Cash and cash equivalents at March 31, 2023 decreased $51.9 million since December 31, 2022. At March 31, 2023 and December 31, 2022, cash and cash equivalents amounted to 5% and 6% of total assets, respectively. The decrease in cash and cash equivalents since December 31, 2022 was related primarily to funding loan growth.

Investments

At March 31, 2023, the fair value of the investment securities portfolio amounted to $830.9 million, an increase of $10.5 million, or 1%, since December 31, 2022. The investment securities portfolio at fair value represented 19% and 18% of total assets at March 31, 2023 and December 31, 2022, respectively. The increase resulted primarily from an increase in the fair value of the Company's debt securities portfolio of $26.2 million, during the three months ended March 31, 2023, caused primarily by lower market interest rates compared to December 31, 2022, partially offset by principal pay-downs, calls and maturities during the period. As of March 31, 2023 and December 31, 2022, the Company's investment securities 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 three months ended March 31, 2023, the Company has no purchases or sales of debt securities and had principal pay-downs, calls and maturities totaling $16.4 million.

Table of Contents

During the three months ended March 31, 2022, the Company purchased $68.3 million in debt securities, had principal pay-downs, calls and maturities totaling $26.1 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 $98.0 million at March 31, 2023, compared to $124.1 million at December 31, 2022. The Company attributes the change in net unrealized losses compared to December 31, 2022 to a decrease in market interest rates during the period.

The mix of investment securities remained relatively unchanged at March 31, 2023 compared to December 31, 2022. The effective duration of the debt securities portfolio at March 31, 2023 was approximately 4.9 years compared to 5.0 years at December 31, 2022.

Loans

As of March 31, 2023, total loans increased $49.6 million, or 2%, compared to December 31, 2022. The mix of loans within the Company's loan portfolio remained relatively unchanged with commercial loans amounting to 87% of total loans at both March 31, 2023 and December 31, 2022.

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 three months ended March 31, 2023,

•Commercial real estate loans increased $8.1 million, or 0.4%, compared to December 31, 2022.

•Commercial and industrial loans increased by $9.4 million, or 2.3%, compared to December 31, 2022.

•Commercial construction loans increased by $32.7 million, or 7.7%, since December 31, 2022. The increase resulted from strong customer demand.

•Total retail loans decreased by $556 thousand, or 0.1%, since December 31, 2022.

At March 31, 2023, commercial loan balances participated out to various banks amounted to $58.3 million, compared to $59.1 million at December 31, 2022. 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 $101.7 million and $94.8 million at March 31, 2023 and December 31, 2022, 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 the Company's loan portfolio asset quality at the dates indicated:


(Dollars in thousands)	March 31, 2023			December 31, 2022			March 31, 2022

Allowance for credit losses for loans to total loans	1.70		%	1.66		%	1.63		%

The Company had no OREO at March 31, 2023, December 31, 2022 or March 31, 2022, and therefore non-performing loans were the only component of non-performing assets. The slight increase in non-performing loans at March 31, 2023 compared to December 31, 2022 was due primarily to commercial relationships placed on non-accrual status during the period, partially offset by payoffs, credit upgrades and principal pay-downs. During the second quarter of 2022, two commercial relationships, amounting to $17.9 million, were upgraded and restored to accrual status due to improved financial strength and consistent payment history.

At March 31, 2023 and December 31, 2022, adversely classified loans amounted to $46.4 million and $47.0 million, respectively. Adversely classified loans that were performing amounted to $38.9 million and $40.9 million at March 31, 2023 and December 31, 2022, respectively. Adversely classified loans which were included in non-accrual loans amounted to $7.5 million and $6.1 million at March 31, 2023 and December 31, 2022, respectively.

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 2022 Annual Report on Form 10-K. See Note 4, "ACL for Loans," to the Company's audited consolidated financial statements contained in the 2022 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 under the current expected credit loss ("CECL") methodology.

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 for loans 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 non-cancellable 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 $4.7 million as of March 31, 2023 and $4.3 million at December 31, 2022. The provision for unfunded commitments for the three months ended March 31, 2023 amounted to $418 thousand compared to a benefit of $295 thousand for the three months ended March 31, 2022.

Based on the foregoing, management believes that the Company's ACL for loans and reserve for unfunded commitments is adequate as of March 31, 2023.

Deposits

As of March 31, 2023, customer deposits decreased $19.7 million, or 0%, since December 31, 2022. Checking account balances decreased $151.9 million, or 7%, money market and savings account balances increased $44.3 million, or 3%, and certificates of deposit account balances increased $87.9 million, or 31%.

Table of Contents

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


	March 31, 2023				December 31, 2022				March 31, 2022

Deposits	$	4,016,156	100	%	$	4,035,806	100	%	$	4,034,500	100	%

Total customer deposits include reciprocal balances from checking, money market deposits and CDs received from participating banks in nationwide deposit networks as a result of our customers electing to participate in Company offered programs which allow for enhanced FDIC insurance. Under this enhanced deposit insurance program, the equivalent of the customers' original deposited funds are reciprocated back through the network to the Company and are carried within the appropriate category under deposits. The Company's balances in these reciprocal products were $721.1 million and $589.7 million, at March 31, 2023 and December 31, 2022, respectively.

In addition to enhanced FDIC insured products, we pledge investment securities as collateral for certain municipal balances as needed. Uninsured deposits, not collateralized, amounted to 36% of total deposits. We had significant additional capacity to further utilize enhanced FDIC insured products.

Borrowed Funds

The Company had borrowed funds outstanding of $3.2 million at both March 31, 2023 and December 31, 2022, which were comprised of FHLB advances related to specific lending projects under the FHLB's community development and affordable housing programs as well as a small portion of borrowed funds from a New Hampshire Business Finance Authority borrowing under a New Hampshire community development program linked to a commercial loan.

See also "Liquidity" below for additional information on borrowing capacity.

Subordinated Debt

The Company had outstanding subordinated debt, net of deferred issuance costs, of $59.3 million at March 31, 2023 compared to $59.2 million at December 31, 2022.

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 $311.3 million at March 31, 2023, compared to $282.3 million at December 31, 2022, an increase of $29.1 million, or 10%. The increase was due primarily to an increase in retained earnings of $8.0 million and a reduction in the AOCL, which was driven by an increase in the fair value of debt securities ($20.2 million, net of tax), resulting from lower market interest rates during the period.

For the three months ended March 31, 2023 and March 31, 2022, the Company declared cash dividends of $2.8 million and $2.5 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 10,395 shares and 8,915 shares, totaling $370 thousand and $346 thousand, respectively.

On April 18, 2023, the Company announced a quarterly dividend of $0.23 per share to be paid on June 1, 2023 to shareholders of record as of May 11, 2023.

Table of Contents

Derivatives and Hedging

The Company had no fair value or cash flow hedges at either March 31, 2023 or December 31, 2022.

The notional value of back-to-back interest-rate swaps with customers and counterparties amounted to $7.7 million at March 31, 2023 and $7.8 million at December 31, 2022. The fair value of assets and corresponding liabilities associated with these swaps and carried on the Company's Consolidated Balance Sheets was $624 thousand at March 31, 2023 compared to $782 thousand at December 31, 2022.

The notional value of RPAs sold amounted to $46.9 million at March 31, 2023 and $24.7 million at December 31, 2022. The fair value of RPAs, carried on the Company's Consolidated Balance Sheets as a liability, was $98 thousand at March 31, 2023 and $73 thousand at December 31, 2022.

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 and access to the FRB Discount Window. At March 31, 2023, the Bank had the capacity to borrow additional funds from the FHLB and FRB Discount Window of up to approximately $790.0 million and $310.0 million, respectively.

In April 2023, we pledged additional collateral to the FHLB and intend to participate in the FRB’s Bank Term Funding Program. We anticipate these changes will increase our secured borrowing capacity to approximately $1.4 billion, exclusive of any borrowings outstanding.

Management believes that the Company has adequate liquidity to meet its obligations. However, if general economic conditions, potential recession in the United States and our market areas, continuation of recent uncertainty in the banking industry, changes in market interest rates, persistence of the current 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 13.55% and 10.64%, respectively, at March 31, 2023, compared to 13.49% and 10.56%, respectively, at December 31, 2022. The increases were driven primarily by an increase in retained earnings, partially offset by commercial loan growth during the period.

Tier 1 capital to average assets amounted to 8.47% at March 31, 2023, compared to 8.10% at December 31, 2022. The increase was driven primarily by the increase in retained earnings noted above, partially offset by an increase in average assets, due primarily to commercial loan growth.

Table of Contents

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.

Wealth assets under management and wealth assets under administration amounted to $930.7 million and $206.6 million, respectively, at March 31, 2023, representing increases of $39.3 million, or 4%, and $8.0 million, or 4%, respectively, compared to December 31, 2022. The increases in wealth assets under management and administration were attributable primarily to increase in market values during the three months ended March 31, 2023.

Refer to Part II, Item 7A, "Quantitative and Qualitative Disclosures About Market Risk" of the Company's 2022 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.

Over the past twelve months the Prime Lending Rate has increased 475 basis points and the Company’s net interest margin benefited as increases in asset yields exceeded increases in the costs of funds, which often lag asset yield increases over the short term in a rising rate environment. Absent further increases in the Prime Lending Rate and assuming a static balance, future increases in the cost of funds may exceed increases in asset yields and reduce net interest margin in the interest rates unchanged scenario.

The table below summarizes the results from and compares the percent change in net interest income to the rates unchanged scenario, assuming a static balance sheet, for a 24-month period at March 31, 2023 and December 31, 2022.

At March 31, 2023, the Company's net interest income sensitivity simulation results were for a decrease in net interest income in both rising and declining interest rate scenarios. At March 31, 2023 compared to December 31, 2022, net interest income sensitivity in the rising interest rate scenarios shifted from an increase in net interest income to a decrease and net interest income sensitivity in the declining interest rate scenario decreased.

•In the 200 and 400 basis point rising interest rate scenarios, net interest income was projected to decrease in the first 24 months compared to an increase at December 31, 2022 primarily due to a shift in deposit composition from non-interest-bearing account balances into interest-bearing account balances that have a higher level of interest rate sensitivity, and from a lower balance of net short-term liquidity that repriced immediately.

•In the 200 basis point declining interest rate scenario, the percent decrease in net interest income was lower compared to the results at December 31, 2022. At March 31, 2023, deposit yields increased above the lower levels experienced at December 31, 2022 when deposit yields were closer to zero. As deposit yields increase, it allows for a higher level of rate declines in the 200 basis point declining rate scenario, which improved net interest income sensitivity results.


(Dollars in thousands, except for percentage data)	March 31, 2023		December 31, 2022


Changes in interest rates	Percentage Change		Percentage Change
Rates Rise 400 Basis Points	(0.73)	%	1.20	%
Rates Rise 200 Basis Points	(0.48)	%	0.45	%
Rates Unchanged	—	%	—	%
Rates Decline 200 Basis Points	(2.51)	%	(5.34)	%

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 2022 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 March 31, 2023.

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 March 31, 2023) that materially affected, or is 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 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 2022 Annual Report on Form 10-K. However, if the United States or the markets in which we operate encounter sustained economic stress or recession, many of the risk factors identified in the Company’s 2022 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 key risk areas including Economic & Financial Markets, Liquidity, Credit and Collateral, Capital and Operations, among others.

Recent bank failures and the related negative impact on customer confidence in the safety and soundness of the banking industry may adversely affect our business, earnings and financial condition.

When other financial institutions experience severe financial difficulties it could result in an adverse impact on the regional banking industry, generally, and the business environment in which the Company operates. The failures of three large regional banks in 2023 have resulted in significant market volatility among publicly traded bank holding companies which has caused uncertainty in the investor community and bank customers, generally. This uncertainty may negatively impact customer confidence in the safety and soundness of regional banks and, as a result, the Company’s customers may choose to withdraw some or all of their deposited funds, and seek higher yielding alternatives, which could have a materially adverse impact on our liquidity, cost of funding, loan funding capacity, net interest margin, capital and results of operations.

Management continues to monitor the ongoing events concerning the recent bank failures, potential bank failures and volatility within the financial services industry generally, together with any responsive measures that may be taken by the banking regulators in an attempt to mitigate or manage potential turmoil in the financial services industry.
