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

(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 (e), "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 Bank's investment in a qualifying New Market Tax Credit ("NMTC") project. The NMTC Investment Fund is the Company's only unconsolidated Variable Interest Entity ("VIE"). Otherwise, 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 June 30, 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.

(c) Unconsolidated Variable Interest Entity / Proportional Accounting

In March 2023, the Bank made an equity contribution to the NMTC Investment Fund, a newly formed Delaware limited liability company, in order to invest in the NMTC program 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 accounting 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 and six months ended June 30, 2023, the related amortization expense amounted to $147 thousand and $191 thousand, respectively, and the related tax credits amounted to $153 thousand and $306 thousand, respectively.

(d) Income Taxes

Deferred income taxes are recognized based on the expected future tax consequences of differences between the financial statement and tax basis of assets and liabilities, calculated using currently enacted tax rates. Management records net deferred tax assets to the extent we believe these assets will more likely than not be realized. In making this determination, we consider all available positive and negative evidence, including recent financial operations and projected future taxable income.

During the second quarter of 2023, the Company sold debt securities with an amortized cost of approximately $87.2 million realizing net losses of $2.4 million. For the majority of the realized losses, the Company had capital gains available for loss carry-back. At June 30, 2023, the Company established a $206 thousand valuation allowance against the capital loss carryforward deferred tax asset, for the amount management believes is not more-likely-than-not to be realized during the five-year capital loss carryforward period.

(e) 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.

(f) Subsequent Events

The Company has evaluated subsequent events and transactions from June 30, 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 June 30, 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 fifteen months. Management concluded that no ACL for available-for-sale securities was necessary as of June 30, 2023 and anticipates they will mature or be called at par value.

Total debt securities	$	820,004	$	706,953

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 $131.8 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 $696.8 million and $804.2 million at June 30, 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 experiencing financial difficulty 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 for 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 or not a delay in payment resulting from the current modification is insignificant.

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 six months ended June 30, 2023, there were no subsequent defaults on loans that had been modified within the preceding twelve months for borrowers experiencing financial difficulty, and at June 30, 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 June 30, 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 three months indicated:

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

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

The Company had no derivatives designated as cash flow hedges at either June 30, 2023 or December 31, 2022.

Derivatives designated as hedging instruments

Fair value hedges

Derivatives designated as fair value hedges are utilized to mitigate the risk of adverse interest-rate fluctuations on specifically identified assets or liabilities. The Company's fair value hedges are used to manage its exposure to changes in the fair value of hedged items caused by changes in interest rates.

During the second quarter of 2023, the Company entered into two pay fixed, receive float, interest rate swaps to hedge against fixed-rate commercial real estate loan pools. Each swap has a notional value of $25.0 million and a term of two years. At June 30, 2023, these interest rate swaps were designated as fair value hedges and involve the net settlement of receiving floating-rate payments from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount.

Derivatives not subject to hedge accounting

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 June 30, 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 six months ended June 30, 2023 or June 30, 2022.

Interest-rate swaps with counterparties are subject to master netting agreements, while interest-rate swaps with customers are not. At June 30, 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 ("RPAs") 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 RPAs and the customers' loan are secured by the same collateral.

Credit Risk

The Company had two active interest-rate swap institutional counterparties which were rated A and A+ by Standard & Poor's and A2 by Moody's, at June 30, 2023. When the Company has credit risk exposure, collateral is posted by counterparties. 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. At June 30, 2023, the Company had $991 thousand credit risk exposure relating to interest-rate swaps with counterparties and the cash collateral posted by counterparties amounted to $390 thousand. At December 31, 2022, the Company had credit risk exposure relating to interest-rate swaps with counterparties of $708 thousand and the 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 June 30, 2023, the fair value of derivatives related to these agreements was at a net asset position of $991 thousand, which excludes any adjustment for nonperformance risk. The Company has minimum collateral posting thresholds with certain of its derivative counterparties and as of June 30, 2023, has not posted collateral related to these agreements.

Other Derivative Related Activity

At both June 30, 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 June 30, 2023, management considers the risk of material swap loss exposure related to

25

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

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 June 30, 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.

(1)Before application of the capital conservation buffer of 2.50% as of June 30, 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.

26

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

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 June 30, 2023. At June 30, 2023, the capital conservation buffer amounted to $92.6 million for both the Company and the Bank.

Stock Option Awards

The Company issued no stock options during the six months ended June 30, 2023. The table below provides a summary of the options granted, including the weighted average fair value, the fair value as a percentage of the market value of the stock at the date of grant and the average assumptions used in the model for the prior period:

	Six months ended
	June 30, 2022
Options granted	17,060
Term in years	10
Weighted average assumptions used in the fair value model:
Expected volatility	44		%

Options granted during the first six months of 2022 generally vest 50% in year two and 50% in year four, on or about the anniversary date of the awards.

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 $46 thousand and $96 thousand for the three and six months ended June 30, 2023, respectively, compared to $52 thousand and $100 thousand for the three and six months ended June 30, 2022, 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:

	Six months ended June 30,
Restricted Stock Awards (number of underlying shares)	2023		2022
Two-year vesting	9,915		8,823
Four-year vesting	32,719		22,116
Performance-based vesting	31,270		22,254
Total restricted stock awards granted	73,904		53,193
Weighted average grant date fair value	$	32.04	$	38.57

Stock-based compensation expense recognized in association with stock awards, mainly restricted stock awards, amounted to $525 thousand and $932 thousand for the three and six months ended June 30, 2023, respectively, compared to $521 thousand and $881 thousand for the three and six months ended June 30, 2022, respectively.

Stock in Lieu of Directors' Fees

Non-employee members of the Company's Board of Directors (the "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 $58 thousand and $123 thousand for the three and six months ended June 30, 2023, respectively, compared to $64 thousand and $134 thousand for the three and six months ended June 30, 2022, 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 June 30,		Six months ended June 30,
	2023	2022	2023	2022
Basic weighted average common shares outstanding	12,228,081	12,107,804	12,191,857	12,082,041
Dilutive shares	16,782	43,908	26,878	54,569
Diluted weighted average common shares outstanding	12,244,863	12,151,712	12,218,735	12,136,610

Stock options outstanding that were determined to be anti-dilutive and therefore excluded from the calculation of dilutive shares amounted to 105,719 and 48,373 for the three and six months ended June 30, 2023, respectively, compared to 48,662 and 34,473 for the three and six months ended June 30, 2022, respectively. These stock options, which were not dilutive, may potentially dilute earnings per share in the future.

Unvested participating restricted stock awards amounted to 136,939 shares and 106,658 shares as of June 30, 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.

29

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

The following tables summarize significant assets and liabilities carried at fair value and placement in the fair value hierarchy at the dates specified:

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, fair value hedges 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. The Company utilizes third-party vendors to provide valuations on its derivative assets and liabilities. 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,

30

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

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 June 30, 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 June 30, 2023 and December 31, 2022:

	Fair Value
(Dollars in thousands)	June 30, 2023		December 31, 2022		Valuation Technique	Unobservable Input	Unobservable Input Value or Range
Assets measured on a non-recurring basis:
Individually evaluated loans (collateral dependent)	$	954	$	740	Appraisal of collateral	Appraisal adjustments(1)	15% - 50%

_______________________________

(1)Appraisals may be adjusted by management for qualitative factors such as economic conditions and estimated liquidation expenses.

Estimated Fair Values of Assets and Liabilities

In addition to disclosures regarding the measurement of assets and liabilities carried at fair value on the Company's Consolidated Balance Sheets, the Company is also required to disclose fair value information about financial instruments for which it is practicable to estimate that value, whether or not recognized on the Company's Consolidated Balance Sheets. 

Financial instruments for which the fair value is disclosed but not recognized on the Company's Consolidated Balance Sheets are summarized below. The table includes the carrying value, estimated fair value and its placement in the fair value hierarchy as follows:

Excluded from the tables above are certain financial instruments with carrying values that approximated their fair value at the dates indicated, as they were short-term in nature or payable on demand. These include cash and cash equivalents, accrued interest and non-term deposit accounts. The respective carrying values of these instruments would all be classified within Level 1 in the fair value hierarchy.

31

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

Also excluded from these tables are the fair values of commitments for unused portions of lines of credit and commitments to originate loans that were short-term, at current market rates and estimated to have no significant change in fair value.

Key Financial Highlights

Key financial results at or for the three months ended June 30, 2023 are as follows:

•Net income amounted to $9.7 million, or $0.79 per diluted common share, compared to $8.2 million, or $0.67 per diluted common share, for the three months ended June 30, 2022, compared to $10.8 million, or $0.88 per diluted common share, for the three months ended March 31, 2023.

•Included in pre-tax income were $3.4 million in Employee Retention Credits ("ERC"), which the Company recorded as a reduction to salary and benefits expense, a loss on the sale of debt securities of $2.4 million and a provision for credit losses of $2.3 million.

•On balance sheet liquidity remained strong at June 30, 2023 with cash and cash equivalents amounting to $258.8 million, while wholesale borrowings amounted to only $3.3 million.

•Total investment securities at fair value amounted to $712.9 million at June 30, 2023, compared to $830.9 million at March 31, 2023, a decrease of $118.0 million, or 14%. The decrease was attributable principally to the sale of debt securities during the period and, to a lesser extent, principal pay downs, calls and maturities.

•Total loans amounted to $3.35 billion, an increase of $115.5 million, or 4%, compared to March 31, 2023. Loans outstanding have increased 9% compared to June 30, 2022.

•Total customer deposits amounted to $4.08 billion, an increase of $59.4 million, or 1%, compared to March 31, 2023. Customer deposits have increased 1% compared to June 30, 2022.

•As part of its asset liability management strategy, the Company undertook the initiatives noted below to increase asset sensitivity and enhance future earnings.

◦The Company sold $84.8 million in debt securities and reinvested the proceeds into higher yielding short-term investments.

◦The Company entered into two, pay fixed, receive float, interest rate swaps to hedge against fixed-rate commercial real estate loan pools. Each swap has a notional value of $25.0 million and a term of two years.

◦The Company estimates that these initiatives provide an annualized increase to interest income of approximately $2.0 million, based on interest rates and balances outstanding at June 30, 2023.

Liquidity & Funding Capacity

•Uninsured deposits amounted to 36% of total deposits.

•Deposit balances that utilize third-party enhanced Federal Deposit Insurance Corporation ("FDIC") insured products amounted to $796.8 million. Additional capacity to utilize these enhanced FDIC insured products exceeds the Company's total deposits balance.

•There were no brokered deposits outstanding. Borrowed funds amounted to $3.3 million and related to the Company's 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.

•FHLB and Federal Reserve Bank of Boston secured borrowing capacity amounted to $1.1 billion.

•The Company has several brokered deposit relationships (unsecured borrowings) which management estimated could provide an additional $800.0 million in 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 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 (e), "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 June 30, 2023 and June 30, 2022

Unless otherwise indicated, the reported results are for the three months ended June 30, 2023 with the "prior year period" being the three months ended June 30, 2022. Average yields are presented on an annualized tax equivalent basis.

Net Income

Net income for the three months ended June 30, 2023, amounted to $9.7 million, an increase of $1.5 million, or 19%, compared to the three months ended June 30, 2022.

•The increase in net income during the period was due primarily to an increase in net interest income of $2.3 million and a decrease in non-interest expense of $1.2 million, partially offset by a decrease in non-interest income of $1.3 million. The components of the increase in net income are detailed below.

Net Interest Income

Net interest income for the three months ended June 30, 2023, amounted to $38.1 million, an increase of $2.3 million, or 6%, compared to the three months ended June 30, 2022.

•The increase in net interest income during the period was due largely to increases in loan interest income of $9.7 million and other interest-earning asset income of $1.5 million, partially offset by an increase in deposit interest expense of $9.0 million, due primarily to higher market interest rates over the comparable periods and increased competition for deposits from bank and non-bank alternatives.

Net Interest Margin

Three months ended – June 30, 2023 compared to June 30, 2022

Tax-equivalent net interest margin ("net interest margin") (non-GAAP) was 3.55% for the three months ended June 30, 2023, compared to 3.45% for the three months ended June 30, 2022.

Net interest margin compared to the prior year quarter was impacted by the following factors:

•Average interest-earning deposits with banks decreased $58.3 million, or 28%, while the yield increased 413 basis points. The decrease in average balance resulted primarily from funding loan growth, partially offset by a decrease in

37

average debt securities and an increase in average total deposits. The increase in yield reflected a significant increase in market interest rates during the period.

•Average debt securities decreased $54.3 million, or 6%, while the tax-equivalent yield increased 20 basis points. The decrease in average balance resulted from principal pay-downs, calls, maturities and sales of debt securities during the three months ended June 30, 2023, with funds redeployed into higher yielding interest earning deposits.

•Average loan balances increased $248.5 million, or 8%, and the tax-equivalent yield increased 86 basis points. The increase in loan yields resulted primarily from increases in market interest rates during the period.

•Average total deposits increased $94.6 million, or 2%, and the yield increased 90 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 nine months.

Refer to the Company's Form 10-Q for the quarterly period ended March 31, 2023, filed with the SEC on May 9, 2023, 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 June 30, 2023, compared to the three months ended June 30, 2022. 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 June 30, 2023, amounted to $2.3 million, compared to $2.4 million for the three months ended June 30, 2022.

•The provision expense for the second quarter of 2023 resulted mainly from an increase in loans outstanding and, to a lesser extent, an increase in off balance sheet commitments during the period.

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 June 30, 2023, amounted to $2.8 million, a decrease of $1.3 million, or 32%, compared to the three months ended June 30, 2022.

•Non-interest income for the three months ended June 30, 2023 included losses on sales of debt securities of $2.4 million and gains on equity securities of $189 thousand. Non-interest income during the three months ended June 30, 2022 had no losses on sales of debt securities and losses on equity securities of $429 thousand.

•Excluding the items above, non-interest income increased $487 thousand, or 11%, due primarily to an increase in deposit and interchange fees of $295 thousand.

Non-Interest Expense

Non-interest expense for the three months ended June 30, 2023, amounted to $25.6 million, a decrease of $1.2 million, or 5%, compared to the three months ended June 30, 2022. The decrease resulted primarily from a decrease in salaries and employee benefits of $1.6 million, due primarily to the receipt of $3.4 million in ERC, which were recorded as a reduction to salary and benefits expense.

•Excluding the ERC, non-interest expense increased $2.2 million, or 8%, due primarily to an increase in salaries and benefits of $1.8 million, or 10%.

•The increase in non-interest expense, excluding the ERC, was impacted by increases in advertising and public relations expenses of $244 thousand and deposit insurance premiums of $249 thousand, partially offset by a decrease in technology and telecommunications expenses of $283 thousand.

Income Taxes

The effective tax rate for the three months ended June 30, 2023, was 25.6%, compared to 23.7% for the three months ended June 30, 2022. The increase in the effective rate for the current quarter compared to the prior year quarter resulted primarily from the transfers of funds from the Bank's investment subsidiary corporations and a partially non-deductible loss on the sale of debt securities. The Company established a valuation allowance against the capital loss carryforward deferred tax asset which resulted from the sale of securities.

Results of Operations for the six months ended June 30, 2023 and June 30, 2022

Unless otherwise indicated, the reported results are for the six months ended June 30, 2023 with the "prior year period," being the six months ended June 30, 2022. Average yields are presented on an annualized tax equivalent basis.

Net Income

Net income for the six months ended June 30, 2023, amounted to $20.5 million, an increase of $2.0 million, or 11%, compared to the six months ended June 30, 2022.

•The increase in net income during the current period was due primarily to an increase in net interest income of $8.2 million, partially offset by an increase in the provision for credit losses of $2.1 million and a decrease in non-interest income of $2.2 million. The components of the increase in net income are detailed below.

40

Net Interest Income

Net interest income for the six months ended June 30, 2023, amounted to $78.1 million, an increase of $8.2 million, or 12%, compared to the six months ended June 30, 2022.

•The increase in net interest income during the current period was due largely to increases in loan interest income of $18.5 million and other interest-earning asset income of $3.6 million, partially offset by an increase in deposit interest expense of $14.4 million.

Net Interest Margin

Six months ended – June 30, 2023 compared to June 30, 2022

Net interest margin was 3.65% for the six months ended June 30, 2023, compared to 3.36% for the six months ended June 30, 2022.

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

•Average interest-earning deposits with banks decreased $121.4 million, or 41%, while the yield increased 426 basis points. The decrease in average balance resulted primarily from funding loan growth, partially offset by a decrease in average debt securities and an increase in average total deposits. The increase in yield reflected a significant increase in market interest rates since the prior period.

•Average debt securities decreased $33.4 million, or 3%, while the tax-equivalent yield increased 21 basis points. The decrease in average balance resulted from principal pay-downs, calls, maturities and sales of debt securities during the six months ended June 30, 2023, with funds redeployed into higher yielding interest-earning deposits.

•Average loan balances increased $268.9 million, or 9%, and the tax-equivalent yield increased 79 basis points. The increase in loan yields resulted primarily from increases in market interest rates during the period.

•Average total deposits increased $78.7 million, or 2%, and the yield increased 72 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 nine months.

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

Provision for Credit Losses

The provision for credit losses for the six months ended June 30, 2023, amounted to $5.0 million, an increase of $2.1 million, compared to the six months ended June 30, 2022.

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

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 loan, see "Asset Quality" and "ACL for Loans" under "Financial Condition" in this Item 2, below.

Non-Interest Income

Non-interest income for the six months ended June 30, 2023, amounted to $7.6 million, a decrease of $2.2 million, or 22%, compared to the six months ended June 30, 2022.

•Non-interest income for the six months ended June 30, 2023 included losses on sales of debt securities of $2.4 million and gains on equity securities of $173 thousand. Non-interest income during the six months ended June 30, 2022 had gains on sales of debt securities of $1.1 million and losses on equity securities of $495 thousand.

•Excluding the items above, non-interest income increased $661 thousand, or 7%, due primarily to increases in deposit and interchange fees of $541 thousand.

Non-Interest Expense

Non-interest expense for the six months ended June 30, 2023, amounted to $53.7 million, an increase of $1.1 million, or 2%, compared to the six months ended June 30, 2022.

•Non-interest expense for the six months ended June 30, 2023 included $3.6 million in ERC, which were recorded as a reduction to salary and benefits expense. Excluding the ERC, non-interest expense increased $4.7 million, or 9%, primarily due to an increase in salaries and benefits, excluding ERC, of $3.8 million, or 11%.

•The increase in non-interest expense, excluding the ERC, was also impacted by increases in advertising and public relations expenses of $258 thousand, deposit insurance premiums of $368 thousand and other operating expenses of $341 thousand.

Income Taxes

The effective tax rate for the six months ended June 30, 2023, was 24.2%, compared to 23.2% for the six months ended June 30, 2022. The increase in the effective tax rate for the current year compared to the prior year resulted primarily from the transfers of funds from the Bank's investment subsidiary corporations and a partially non-deductible loss on the sale of debt securities. The Company established a valuation allowance against the capital loss carryforward deferred tax asset which resulted from the sale of securities.

Financial Condition

Total assets amounted to $4.50 billion at June 30, 2023, compared to $4.44 billion at December 31, 2022, representing an increase of $64.0 million, or 1%. The balance sheet composition and changes since December 31, 2022, are discussed below.

Cash and cash equivalents

Cash and cash equivalents at June 30, 2023 decreased $8.8 million since December 31, 2022. At both June 30, 2023 and December 31, 2022, cash and cash equivalents amounted to 6% of total assets. The decrease was due primarily to the funding of loan growth, partially offset by sales of debt securities, investment cash flows and deposit growth.

Investments

At June 30, 2023, the fair value of the investment securities portfolio amounted to $712.9 million, a decrease of $107.5 million, or 13%, since December 31, 2022. The investment securities portfolio at fair value represented 16% and 18% of total assets at June 30, 2023 and December 31, 2022, respectively. The decrease was attributable principally to sales of debt securities and, to a lesser extent, principal pay downs, calls and maturities. Debt security sales during the three and six months ended June 30, 2023 were made in order to improve the Company's balance sheet positioning and enhance future earnings. As of June 30, 2023

44

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 six months ended June 30, 2023, the Company purchased no debt securities, had principal pay-downs, calls and maturities totaling $32.4 million, and sold debt securities with an amortized cost of approximately $87.2 million realizing net losses on sales of $2.4 million.

Net unrealized losses on the debt securities portfolio amounted to $113.1 million at June 30, 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 changes in market interest rates during the period.

The mix of investment securities remained relatively unchanged at June 30, 2023 compared to December 31, 2022. The effective duration of the debt securities portfolio at June 30, 2023 was approximately 5.1 years compared to 5.0 years at December 31, 2022.

Loans

As of June 30, 2023, total loans increased $165.1 million, or 5%, compared to December 31, 2022. The mix of loans within the Company's loan portfolio remained relatively unchanged and commercial loans amounted to 87% of total loans at both June 30, 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:

	June 30, 2023				December 31, 2022				June 30, 2022

Net loans	$	3,288,768			$	3,127,878			$	3,034,212

As of June 30, 2023, and compared to December 31, 2022,

•Commercial real estate loans increased $87.9 million, or 5%.

•Commercial and industrial loans increased by $5.6 million, or 1%.

•Commercial construction loans increased by $63.0 million, or 15%. The increase was due primarily to strong demand from existing customers partially driven by low housing inventory.

•Total retail loans increased by $8.7 million, or 2%.

At June 30, 2023, commercial loan balances participated out to various banks amounted to $68.9 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 $107.6 million and $94.8 million at June 30, 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.

The Company had no OREO at June 30, 2023, December 31, 2022 or June 30, 2022, and therefore non-performing loans were the only component of non-performing assets.

At June 30, 2023 and December 31, 2022, adversely classified loans amounted to $42.1 million and $47.0 million, respectively. Adversely classified loans that were performing amounted to $34.5 million and $40.9 million at June 30, 2023 and December 31, 2022, respectively. Adversely classified loans in non-accrual status amounted to $7.6 million and $6.1 million at June 30, 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.

47

The Company's reserve for unfunded commitments amounted to $5.0 million as of June 30, 2023 and $4.3 million at December 31, 2022. The provision for unfunded commitments for the three months ended June 30, 2023 amounted to $225 thousand compared to $214 thousand for the three months ended June 30, 2022. The provision for unfunded commitments for the six months ended June 30, 2023 amounted to $643 thousand compared to a benefit of $81 thousand. The increase in the provision for unfunded commitments resulted primarily from growth in the Company's off-balance sheet commitments.

Based on the foregoing, management believes that the Company's ACL for loans and reserve for unfunded commitments is adequate as of June 30, 2023.

Deposits

As of June 30, 2023, customer deposits increased $39.8 million, or 1%, since December 31, 2022. Checking account balances decreased $64.6 million, or 3%, money market and savings account balances decreased $24.2 million, or 1%, and certificates of deposit ("CD") account balances increased $128.6 million, or 45%, as customers sought higher yielding deposit products in the rising market rate environment.

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

	June 30, 2023				December 31, 2022				June 30, 2022
(Dollars in thousands)	Amount		Percent		Amount		Percent		Amount		Percent
Checking	$	1,975,669	49	%	$	2,040,303	51	%	$	2,170,118	54	%
Money markets and savings	1,684,137		41	%	1,708,311		42	%	1,628,181		40	%
CDs	415,792		10	%	287,192		7	%	218,515		6	%
Deposits	$	4,075,598	100	%	$	4,035,806	100	%	$	4,016,814	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 third-party 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 enhanced insurance products were $796.8 million and $589.7 million, at June 30, 2023 and December 31, 2022, respectively.

As of June 30, 2023, uninsured deposits amounted to 36% of total deposits. Additional capacity to utilize these enhanced FDIC insured products exceeds the Company's total deposits balance at June 30, 2023. Additional capacity to utilize these third-party enhanced FDIC insured products exceeds the Company's total deposits balance.

Borrowed Funds

The Company had borrowed funds outstanding of $3.3 million at both June 30, 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 June 30, 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 $307.5 million at June 30, 2023, compared to $282.3 million at December 31, 2022, an increase of $25.2 million, or 9%. The increase was due primarily to an increase in retained earnings and a decrease in the

48

accumulated other comprehensive loss, which resulted from an increase in the fair value of debt securities.

For the six months ended June 30, 2023 and June 30, 2022, the Company declared cash dividends of $5.6 million and $5.0 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 24,219 shares and 19,524 shares, totaling $746 thousand and $699 thousand, respectively.

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

Derivatives and Hedging

In June of 2023, the Company entered into two pay fixed, receive float, interest rate swaps with a combined notional value of $50.0 million and maturities of two years. Under the interest rate swap agreements, the Company pays a combined fixed interest rate of 4.43% and receives the Secured Overnight Financing Rate. The fair value of these swaps, carried on the Company's Consolidated Balance Sheets as assets, was $260 thousand at June 30, 2023.

The notional value of back-to-back interest-rate swaps with customers and counterparties amounted to $7.7 million at June 30, 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 $753 thousand at June 30, 2023 compared to $782 thousand at December 31, 2022.

The notional value of RPAs sold amounted to $46.9 million at June 30, 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 $81 thousand at June 30, 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 June 30, 2023, the Bank had the capacity to borrow additional funds from the FHLB and FRB Discount Window of up to approximately $830.0 million and $310.0 million, respectively.

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, the persistence of the current inflationary environment in the United States and our

market areas, increased competition for deposits and related changes in deposit customer behavior, 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.

49

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 13.37% and 10.52%, respectively, at June 30, 2023, compared to 13.49% and 10.56%, respectively, at December 31, 2022. The decreases were driven primarily by commercial loan growth, partially offset by an increase in retained earnings during the period.

Tier 1 capital to average assets amounted to 8.62% at June 30, 2023, compared to 8.10% at December 31, 2022. The increase was driven primarily by the increase in retained earnings noted above and a decrease 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.

Wealth assets under management and wealth assets under administration amounted to $1.0 billion and $214.1 million, respectively, at June 30, 2023, representing increases of $117.9 million, or 13%, and $15.5 million, or 8%, respectively, compared to December 31, 2022. The increase in assets under management resulted from an increase in market values as well as assets attracted through new and expanded client relationships.

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 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.

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 June 30, 2023 and December 31, 2022.

•In the 200 and 400 basis point increasing interest rate scenarios, net interest income was projected to be relatively flat 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.

•In the 200 basis point decreasing interest rate scenario, the percent decrease in net interest income was lower compared to the results at December 31, 2022. At June 30, 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.

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 June 30, 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 June 30, 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.

Summary of Significant Accounting Policies

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 (e), "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 Bank's investment in a qualifying New Market Tax Credit ("NMTC") project. The NMTC Investment Fund is the Company's only unconsolidated Variable Interest Entity ("VIE"). Otherwise, 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 June 30, 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.

(c) Unconsolidated Variable Interest Entity / Proportional Accounting

In March 2023, the Bank made an equity contribution to the NMTC Investment Fund, a newly formed Delaware limited liability company, in order to invest in the NMTC program 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 accounting 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 and six months ended June 30, 2023, the related amortization expense amounted to $147 thousand and $191 thousand, respectively, and the related tax credits amounted to $153 thousand and $306 thousand, respectively.

(d) Income Taxes

Deferred income taxes are recognized based on the expected future tax consequences of differences between the financial statement and tax basis of assets and liabilities, calculated using currently enacted tax rates. Management records net deferred tax assets to the extent we believe these assets will more likely than not be realized. In making this determination, we consider all available positive and negative evidence, including recent financial operations and projected future taxable income.

During the second quarter of 2023, the Company sold debt securities with an amortized cost of approximately $87.2 million realizing net losses of $2.4 million. For the majority of the realized losses, the Company had capital gains available for loss carry-back. At June 30, 2023, the Company established a $206 thousand valuation allowance against the capital loss carryforward deferred tax asset, for the amount management believes is not more-likely-than-not to be realized during the five-year capital loss carryforward period.

(e) 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.

(f) Subsequent Events

The Company has evaluated subsequent events and transactions from June 30, 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.

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 $3.4 million and $4.0 million at June 30, 2023 and December 31, 2022, respectively.

At June 30, 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 fifteen months. Management concluded that no ACL for available-for-sale securities was necessary as of June 30, 2023 and anticipates they will mature or be called at par value.

The following tables summarize the duration of unrealized losses for debt securities at June 30, 2023 and December 31, 2022:

Total debt securities	$	820,004	$	706,953

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 $131.8 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 $696.8 million and $804.2 million at June 30, 2023 and December 31, 2022, respectively.

Debt security sales during the three and six months ended June 30, 2023 were made in order to improve the Company's balance sheet positioning and enhance future earnings. Sales of debt securities for the three and six months ended June 30, 2023 and June 30, 2022 are summarized as follows:

ACL for Loans

ACL for Loans

There have been no material changes to the Company's ACL for loans methodology, underwriting practices, or credit risk management system used to estimate credit loss exposure since December 31, 2022. See Note 4, "ACL for Loans," to the Company's audited consolidated financial statements contained in the 2022 Annual Report on Form 10-K. 

Risk ratings and adversely classified loans

The Company's loan risk rating system classifies loans depending on risk of loss characteristics. Adversely classified ratings for loans determined to be of weaker credit range from "special mention," for loans that may need additional monitoring, to the more severe adverse classifications of "substandard," "doubtful," and "loss" based on criteria established under banking regulations.

The following tables present the amortized cost basis of the Company's loan portfolio risk ratings within portfolio classifications, by origination date, or revolving status as of the dates indicated:

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 experiencing financial difficulty 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 for 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 or not a delay in payment resulting from the current modification is insignificant.

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:

	Three months ended

During the six months ended June 30, 2023, there were no subsequent defaults on loans that had been modified within the preceding twelve months for borrowers experiencing financial difficulty, and at June 30, 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 June 30, 2022, additional funding commitments for TDR loans were immaterial.

__________________________________________

(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 derivatives designated as cash flow hedges at either June 30, 2023 or December 31, 2022.

Derivatives designated as hedging instruments

Fair value hedges

Derivatives designated as fair value hedges are utilized to mitigate the risk of adverse interest-rate fluctuations on specifically identified assets or liabilities. The Company's fair value hedges are used to manage its exposure to changes in the fair value of hedged items caused by changes in interest rates.

During the second quarter of 2023, the Company entered into two pay fixed, receive float, interest rate swaps to hedge against fixed-rate commercial real estate loan pools. Each swap has a notional value of $25.0 million and a term of two years. At June 30, 2023, these interest rate swaps were designated as fair value hedges and involve the net settlement of receiving floating-rate payments from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount.

Derivatives not subject to hedge accounting

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 June 30, 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 six months ended June 30, 2023 or June 30, 2022.

Interest-rate swaps with counterparties are subject to master netting agreements, while interest-rate swaps with customers are not. At June 30, 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 ("RPAs") 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 RPAs and the customers' loan are secured by the same collateral.

Credit Risk

The Company had two active interest-rate swap institutional counterparties which were rated A and A+ by Standard & Poor's and A2 by Moody's, at June 30, 2023. When the Company has credit risk exposure, collateral is posted by counterparties. 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. At June 30, 2023, the Company had $991 thousand credit risk exposure relating to interest-rate swaps with counterparties and the cash collateral posted by counterparties amounted to $390 thousand. At December 31, 2022, the Company had credit risk exposure relating to interest-rate swaps with counterparties of $708 thousand and the 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 June 30, 2023, the fair value of derivatives related to these agreements was at a net asset position of $991 thousand, which excludes any adjustment for nonperformance risk. The Company has minimum collateral posting thresholds with certain of its derivative counterparties and as of June 30, 2023, has not posted collateral related to these agreements.

Other Derivative Related Activity

At both June 30, 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 June 30, 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 June 30, 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.

(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 June 30, 2023. At June 30, 2023, the capital conservation buffer amounted to $92.6 million for both the Company and the Bank.

Earnings Per Share

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 June 30,		Six months ended June 30,
	2023	2022	2023	2022
Basic weighted average common shares outstanding	12,228,081	12,107,804	12,191,857	12,082,041
Dilutive shares	16,782	43,908	26,878	54,569
Diluted weighted average common shares outstanding	12,244,863	12,151,712	12,218,735	12,136,610

Stock options outstanding that were determined to be anti-dilutive and therefore excluded from the calculation of dilutive shares amounted to 105,719 and 48,373 for the three and six months ended June 30, 2023, respectively, compared to 48,662 and 34,473 for the three and six months ended June 30, 2022, respectively. These stock options, which were not dilutive, may potentially dilute earnings per share in the future.

Unvested participating restricted stock awards amounted to 136,939 shares and 106,658 shares as of June 30, 2023 and December 31, 2022, respectively.

Fair Value Disclosures [Abstract]

Fair Value Measurements

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 following tables summarize significant assets and liabilities carried at fair value and placement in the fair value hierarchy at the dates specified:

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, fair value hedges 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. The Company utilizes third-party vendors to provide valuations on its derivative assets and liabilities. 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 June 30, 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 June 30, 2023 and December 31, 2022:

	Fair Value
(Dollars in thousands)	June 30, 2023		December 31, 2022		Valuation Technique	Unobservable Input	Unobservable Input Value or Range
Assets measured on a non-recurring basis:
Individually evaluated loans (collateral dependent)	$	954	$	740	Appraisal of collateral	Appraisal adjustments(1)	15% - 50%

_______________________________

(1)Appraisals may be adjusted by management for qualitative factors such as economic conditions and estimated liquidation expenses.

Estimated Fair Values of Assets and Liabilities

In addition to disclosures regarding the measurement of assets and liabilities carried at fair value on the Company's Consolidated Balance Sheets, the Company is also required to disclose fair value information about financial instruments for which it is practicable to estimate that value, whether or not recognized on the Company's Consolidated Balance Sheets. 

Financial instruments for which the fair value is disclosed but not recognized on the Company's Consolidated Balance Sheets are summarized below. The table includes the carrying value, estimated fair value and its placement in the fair value hierarchy as follows:

Excluded from the tables above are certain financial instruments with carrying values that approximated their fair value at the dates indicated, as they were short-term in nature or payable on demand. These include cash and cash equivalents, accrued interest and non-term deposit accounts. The respective carrying values of these instruments would all be classified within Level 1 in the fair value hierarchy.

Also excluded from these tables are the fair values of commitments for unused portions of lines of credit and commitments to originate loans that were short-term, at current market rates and estimated to have no significant change in fair value.

Accounting Policies [Abstract]

Organization of the Company and Basis of Presentation

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 (e), "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 Bank's investment in a qualifying New Market Tax Credit ("NMTC") project. The NMTC Investment Fund is the Company's only unconsolidated Variable Interest Entity ("VIE"). Otherwise, the services offered through the Bank and its subsidiaries are managed as one strategic unit and represent the Company's only reportable operating segment.

Organization of the Company and Basis of Presentation - Basis of Accounting

The accompanying unaudited consolidated interim financial statements, and notes thereto, in this Quarterly Report on Form 10-Q for the quarterly period ended June 30, 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.

Organization of the Company and Basis of Presentation - Reclassifications

Interim results are not necessarily indicative of results to be expected for the entire year, or any future period.

Uses of Estimates

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.

Unconsolidated Variable Interest Entity / Proportional Accounting

Unconsolidated Variable Interest Entity / Proportional Accounting

In March 2023, the Bank made an equity contribution to the NMTC Investment Fund, a newly formed Delaware limited liability company, in order to invest in the NMTC program 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 accounting 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 and six months ended June 30, 2023, the related amortization expense amounted to $147 thousand and $191 thousand, respectively, and the related tax credits amounted to $153 thousand and $306 thousand, respectively.

Income Taxes

Income TaxesDeferred income taxes are recognized based on the expected future tax consequences of differences between the financial statement and tax basis of assets and liabilities, calculated using currently enacted tax rates. Management records net deferred tax assets to the extent we believe these assets will more likely than not be realized. In making this determination, we consider all available positive and negative evidence, including recent financial operations and projected future taxable income. During the second quarter of 2023, the Company sold debt securities with an amortized cost of approximately $87.2 million realizing net losses of $2.4 million. For the majority of the realized losses, the Company had capital gains available for loss carry-back. At June 30, 2023, the Company established a $206 thousand valuation allowance against the capital loss carryforward deferred tax asset, for the amount management believes is not more-likely-than-not to be realized during the five-year capital loss carryforward period.

Recent Accounting Pronouncements

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.

Subsequent Events

Subsequent Events The Company has evaluated subsequent events and transactions from June 30, 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.
