Accounting Policies [Abstract]  
Summary of Significant Accounting Policies Summary of Significant Accounting Policies
 
(a) Organization of the Company and Basis of Presentation
 
The accompanying consolidated financial statements of Enterprise Bancorp, Inc. (the "Company," "Enterprise," "we," or "our"), a Massachusetts corporation, 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 the Company's operations are conducted through the Bank and its subsidiaries.
 
The Bank's subsidiaries include Enterprise Wealth Services, LLC, organized under the laws of the State of Delaware, to offer non-deposit investment products and services. 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 for the purpose of investing in a local NMTC project which provides federal tax incentives for investments in distressed communities. The NMTC are discussed in Note 15, " Income Taxes."

The Company's headquarters and the Bank's main office are located at 222 Merrimack Street in Lowell, Massachusetts. At December 31, 2024, the Company had 27 full-service branch banking offices serving the Northern Middlesex, Northern Essex and Northern Worcester counties of Massachusetts and Southern Hillsborough and Southern Rockingham counties in New Hampshire.

The FDIC and the Massachusetts Division of Banks (the "Division") have regulatory authority over the Bank. The Bank is also subject to certain regulatory requirements of the Board of Governors of the Federal Reserve System (the "Federal Reserve Board") and, with respect to its New Hampshire branch operations, the New Hampshire Banking Department. The business and operations of the Company are subject to the regulatory oversight of the Federal Reserve Board. The Division also retains supervisory jurisdiction over the Company.
 
The accompanying audited consolidated financial statements and notes thereto have been prepared in accordance with U.S. GAAP and the instructions for SEC Form 10-K through the rules and interpretive releases of the SEC under federal securities law. In the opinion of management, the accompanying audited consolidated financial statements reflect all necessary adjustments consisting of normal recurring accruals for a fair presentation. All significant intercompany balances and transactions have been eliminated in the accompanying consolidated financial statements. Certain previous years' amounts in the consolidated financial statements, and notes thereto, have been reclassified to conform to the current year's presentation.

The Company has evaluated subsequent events and transactions from December 31, 2024, through the filing date of this Annual Report on Form 10-K with the SEC for potential recognition or disclosure as required by GAAP and determined that there were no material subsequent events requiring recognition or disclosure.

(b) Segment Reporting 

The Company operates as one strategic unit and therefore has only one reportable operating segment. Substantially all of the Company’s operations are conducted through its wholly owned banking subsidiary, which offers a full range of commercial, residential and consumer loan products, deposit products and cash management services, as well as wealth management and wealth services. The Company's business is not dependent on one, or a few customers, nor upon a particular industry, the loss of which would have a material adverse impact on the financial condition or operations of the Company. The identification of the single reportable business segment was determined based on the nature of the financial services provided, similar customer base and management’s evaluation of the consolidated financial information.

The Company's financial performance is monitored by the Chief Executive Officer and Chief Financial Officer, which together have been designated as the Chief Operating Decision Maker.
The CODM analyzes key metrics including consolidated net income and its major components to strategize and allocate resources. Revenue and expenses reviewed by the CODM are consistent with the consolidated statements of income, and the measure of segment assets reviewed by the CODM is consistent with the consolidated balance sheets.

The Company has reviewed the requirements of ASU 2023-07 and has determined that no additional segment disclosures are required, specifically as a result of the following:
the Company does not use disaggregated segment level for decision-making or resource allocation purposes,
no significant segment-specific expenses or performance metrics are used internally for decision-making or resource allocation purposes, and
the level of financial consolidation presented in our consolidated financial statements aligns with the CODM’s internal reporting and decision-making process

(c) Merger

On December 8, 2024, the Company entered into an Agreement and Plan of Merger (the "Merger Agreement") with Independent Bank Corp., a Massachusetts corporation ("Independent"), and Rockland Trust Company, a Massachusetts-chartered trust company and wholly owned subsidiary of Independent ("Rockland Trust"). Pursuant to the Merger Agreement, the Company will merge with and into Independent, with Independent being the surviving corporation (the "Merger"). Upon completion of the Merger, each outstanding share of Company common stock will convert into the right to receive 0.60 shares of Independent common stock and $2.00 in cash (the "Merger Consideration"). Each outstanding option to acquire a share of Company common stock, whether or not vested, will be converted into the right to receive cash in an amount equal to the amount by which the per share cash equivalent of the Merger Consideration (calculated in accordance with the Merger Agreement) exceeds the exercise price of the option. In addition, each award of Company restricted stock, whether or not vested, that is outstanding immediately prior to the effective time of the Merger will fully vest and be canceled and converted into the right to receive the Merger Consideration. Following the Merger, Enterprise Bank will merge with Rockland Trust, with Rockland Trust being the surviving institution. Completion of the Merger is subject to customary closing conditions, including receipt of regulatory approvals and approval of the Company’s shareholders. The Merger is expected to close in the second half of 2025. The Company has scheduled a Special Shareholder Meeting for April 3, 2025 to vote on the Merger and other related proposals. No vote of Independent shareholders is required.

(d) Uses of Estimates

In preparing the consolidated 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 years 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. The most significant areas in which management applies critical assumptions and estimates are the estimates of the allowance for credit losses for loans and available for sale securities, the reserve for unfunded commitments, and the impairment review of goodwill, which are each discussed below.

(e) Cash and Cash Equivalents

Cash equivalents are defined as highly liquid investments with original maturities of three months or less, that are readily convertible to known amounts of cash and present insignificant risk of changes in value due to changes in interest rates. The Company's cash and cash equivalents may be comprised of cash on hand and cash items due from banks, interest-earning deposits with banks (deposit accounts, excess reserve cash balances, money markets, and money market mutual fund accounts) and overnight and term federal funds sold to money center banks. Balances in cash and cash equivalents will fluctuate due primarily to the timing of net cash flows from deposits, borrowings, loans and investments, and the immediate liquidity needs of the Company.

(f) Restricted Cash and Investments

Certain of the Company's derivative agreements contain provisions for collateral to be posted if the derivative exposure exceeds a threshold amount. When the Company has pledged cash as collateral in relation to certain derivatives, the cash is carried as
restricted cash within "Interest-earning deposits with banks." See Note 9, "Derivatives and Hedging Activities," to the Company's consolidated financial statements of this Form 10-K below for more information about the Company's collateral related to its derivatives.

As a member of the FHLB, the Company is required to purchase certain levels of FHLB capital stock at par value in association with outstanding advances from the FHLB. From time-to-time, the FHLB may initiate the repurchase, at par value, of "excess" levels of its capital stock held by member banks. This stock is classified as a restricted investment and is carried at cost, which management believes approximates fair value. FHLB stock represents the only restricted investment held by the Company.

Management regularly reviews its holdings of FHLB stock for impairment, and as of December 31, 2024, the Company has determined that no allowance for credit losses on FHLB stock was necessary.

(g) Investment Securities
 
Investments in debt securities that are intended to be held for indefinite periods of time, but which may not be held to maturity or on a long-term basis are considered to be "available-for-sale" and are carried at fair value.

Included as available-for-sale are debt securities that are purchased in connection with the Company's asset-liability risk management strategy and that may be sold in response to changes in interest rates, prepayment risk and other related factors. In instances where the Company has the positive intent to hold debt securities to maturity, these securities will be classified as held-to-maturity and carried at amortized cost. As of the balance sheet dates, all the Company's debt securities were classified as available-for-sale and carried at fair value.

Net unrealized appreciation and depreciation on debt securities available-for-sale, net of applicable income taxes, are recorded in the Company's Consolidated Statement of Comprehensive Income as a component of "Accumulated other comprehensive (loss) income." The net unrealized gain or loss in the Company's debt security portfolio fluctuates as market interest rates rise and fall. Due to the fixed rate nature of this portfolio, as market rates fall, the value of the portfolio rises, and as market rates rise, the value of the portfolio declines. The unrealized gains or losses on debt securities will also decline as the securities approach maturity.

The Company's equity securities are carried at fair value with changes in fair value recognized in the Company's Consolidated Income Statement as a component of "Other income." The net gains and losses on equity securities that will be recognized as a component of "Non-interest income" in the future will depend on the amount of dollars invested in equities, the magnitude of changes in equity markets and the amount of gains or losses realized through equity sales.
 
Investment securities' discounts are accreted and premiums are amortized over the period of estimated principal repayment using methods that approximate the interest method. Gains or losses on the sale of investment securities are recognized on the trade date on a specific identification basis.

ACL for Available-for-Sale Securities Methodology

In accordance with ASC "Financial Instruments—Credit Losses (Topic 326), the Company's expected credit losses on available-for-sale debt securities are presented as an allowance rather than as a write-down. The Company measures expected credit losses on available-for-sale securities based upon the unrealized gain or loss position of the security. For available-for-sale debt securities in an unrealized loss position, the Company evaluates qualitative criteria to determine any expected loss unless the Company intends to sell, or it is more likely than not that the Company will be required to sell before recovery of the amortized cost. In the latter two circumstances, the Company recognizes the entire difference between the security’s amortized cost basis and its fair value as a write-down of the investment balance with a charge to earnings. Otherwise, management’s analysis considers various factors, which include among other considerations (1) the present value of the cash flows expected to be collected compared to the amortized cost of the security, (2) duration and magnitude of the decline in value, (3) the financial condition of the issuer or issuers, and (4) structure of the security. If the Company does not expect to recover the entire amortized cost basis of the security, an allowance for credit losses for available-for-sale securities would be recorded, with a related charge to earnings, limited by the difference of the amortized cost of the security to its fair value. Subsequent measurements of the ACL for available-for-sale securities may result in a reversal of the allowance for credit losses, not to exceed the amount initially recognized. In addition, the Company has elected to exclude accrued interest from the measurement of the allowance for credit losses for available-for-sale debt securities and to continue to write-off uncollectible accrued interest receivable by reversing interest income.
At December 31, 2024, management performed its quarterly analysis of all securities with unrealized losses and determined that all were attributable to increases in market interest rates. Management concluded that no ACL for available-for-sale securities was considered necessary as of December 31, 2024 and anticipates they will mature or be called at par value. The Company does not intend to sell these investments and has determined, based upon available evidence, that it is more likely than not that the Company will not be required to sell each security before the recovery of its amortized cost basis.

(h) Loans Held for Sale

Depending on the current interest-rate environment, management projections of future interest rates and the overall asset-liability management program of the Company, management may elect to sell those fixed and adjustable-rate residential mortgage loans which are eligible for sale in the secondary market or hold some or all of this residential loan production for the Company's portfolio. Mortgage loans are generally not pooled for sale, but instead are sold on an individual basis. Enterprise may retain or sell the servicing when selling the loans. Loans sold are subject to standard secondary market underwriting and eligibility representations and warranties over the life of the loan and are subject to an early payment default period covering the first four payments for certain loan sales. Loans held for sale are carried at the lower of aggregate amortized cost or fair value on a separate line on the balance sheet. Fair value is based on comparable market prices for loans with similar rates and terms. When loans are sold, a gain or loss is recognized to the extent that the sales proceeds plus unamortized fees and costs exceed, or are less than, the carrying value of the loans. Gains and losses are determined using the specific identification method.

(i) Loans
 
Loans made by the Company to businesses, non-profits and professional practices include commercial real estate mortgage loans, construction and land development loans, secured and unsecured commercial loans and lines of credit, and letters of credit. Loans made to individuals include conventional residential mortgage loans, home equity lines, residential construction loans on owner-occupied primary and secondary residences, and secured and unsecured personal loans and lines of credit. Most loans granted by the Company are collateralized by real estate, equipment, or receivables and/or are guaranteed by the principals of the borrower.
 
Loans are reported at the principal amount outstanding, net of deferred origination fees and costs. The aggregate amounts of overdrawn deposit accounts are reclassified as loan balances. Loan origination fees received, offset by direct loan origination costs, are deferred and amortized using the straight-line method over three years to five years for lines of credit and demand notes or over the life of the related loans using the level-yield method for all other types of loans. When loans are paid off, the unamortized fees and costs are recognized as an adjustment to interest income.

Certain of the Company's directors, officers, principal shareholders, and their associates are credit customers of the Company in the ordinary course of business. In addition, certain directors are also directors, trustees, officers or shareholders of corporations and non-profit entities or members of partnerships that are customers of the Bank and that enter into loan and other transactions with the Bank in the ordinary course of business. All loans and commitments included in such transactions are on such terms, including interest rates, repayment terms and collateral, as those prevailing at the time for comparable transactions with persons who are not affiliated with the Bank and do not involve more than a normal risk of collectability or present other features unfavorable to the Bank.

From time to time, the Company participates with other banks in the financing of certain commercial projects. In order to qualify for sale accounting under GAAP, the rights and obligations of each participating bank are divided proportionately among the participating banks in an amount equal to their share of ownership and with equal priority among all banks. Each participation is governed by individual participation agreements executed by the lead bank and the participants at loan origination. When a participation qualifies as a sale under GAAP, the balances participated out to other institutions are not carried as assets on the Company's consolidated financial statements. When a participation does not qualify as a sale under GAAP, the loan is carried at gross principal outstanding and the balances participated out to other institutions are carried as secured borrowings on the Company's consolidated financial statements. The Company performs an independent credit analysis of each commitment and a review of the participating institution prior to participation in the loan, and an annual review thereafter of each participating institution. Loans originated by other banks in which the Company is the participating institution are carried in the loan portfolio at the Company's pro rata share of ownership. Participating loans with other institutions provide banks the opportunity to retain customer relationships and reduce credit risk exposure among each participating bank, while providing customers with larger credit vehicles than the individual bank might be willing or able to offer independently.
The Company seeks to lessen its credit risk exposure by managing its loan portfolio to avoid concentration by industry, relationship size and source of repayment, and through sound underwriting practices and the credit risk management function; however, management recognizes that credit losses will occur and that the amount of these losses will fluctuate depending on the risk characteristics of the loan portfolio and economic conditions.

(j) Credit Risk Management and ACL for Loans Methodology

Inherent in the lending process is the risk of loss due to customer non-payment, or "credit risk." The Company's commercial lending focus may entail significant additional credit risks compared to long-term financing on existing, owner-occupied residential real estate. The credit risk management function focuses on a wide variety of factors and early detection of credit issues is critical to minimize credit losses. Accordingly, management regularly monitors these factors, among others, through ongoing credit reviews by the Company's Credit Department, an external loan review service, reviews by members of senior management as well as reviews by the Board's Loan Committee and the Board. These reviews include the assessment of internal credit quality indicators such as, among others, the risk classification of loans, past due and non-accrual loans, loans individually evaluated or with hardship modifications, and the level of foreclosure activity.

Credit Risk Management

The Company's loan risk rating system classifies loans depending on risk of loss characteristics. The classifications range from "substantially risk free" for the highest quality loans and loans that are secured by cash collateral, through a satisfactory range of "minimal," "moderate," "better than average," and "average" risk, all of which are considered "pass" rated credits. The adverse classifications range from "special mention," for loans that may need additional monitoring, to the more severe classifications of "substandard," "doubtful," and "loss" based on criteria established under banking regulations. Loans classified as "substandard" include those characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected. Loans classified as "doubtful" have all the weaknesses inherent in a substandard rated loan with the added characteristic that the weaknesses make collection or full payment from liquidation, based on existing facts, conditions, and values, highly questionable and improbable. Loans classified as "loss" are generally considered uncollectible at present, although long term recovery of part or all of loan proceeds may be possible. These "loss" loans would require a specific loss reserve or charge-off. Loans which are evaluated to be of weaker credit quality are classified as adverse and placed on the "watch asset list" and reviewed on a more frequent basis by management. Adversely classified loans may be accruing or in non-accrual status and may be additionally designated as individually evaluated or restructured, or some combination thereof.

Loans on which the accrual of interest has been discontinued are designated as non-accrual loans and the classified portions are credit downgraded to one of the adversely classified categories noted above. Accrual of interest on loans is generally discontinued when a loan becomes contractually past due, with respect to interest or principal, by 90 days, or when reasonable doubt exists as to the full and timely collection of interest or principal. When a loan is placed on non-accrual status, all interest previously accrued but not collected is reversed against current period interest income. Interest accruals are resumed on such loans only when payments are brought current and have remained current for a period of 180 days or when, in the judgment of management, the collectability of both principal and interest is reasonably assured. Interest payments received on loans in a non-accrual status are generally applied to principal on the books of the Company.

Loans individually evaluated consist primarily of loans for which management considers it probable that not all amounts due (principals and interest) will be collected in accordance with the original contractual terms and, to a lesser extent, if applicable, loans that management deems as individually significant or with unique risk characteristics or for some other reason based on management’s judgement. Management considers the individual payment status, net worth and earnings potential of the borrower, and the value and cash flow of the collateral as factors to determine if a loan will be paid in accordance with its contractual terms.

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.
Individually evaluated adversely classified loans will be considered for upgrade based on the borrower's sustained performance over time and their improving financial condition. Consistent with the criteria for returning non-accrual loans to accrual status, the borrower must demonstrate the ability to continue to service the loan in accordance with the original or modified terms and, in the judgment of management, the collectability of the remaining balances, both principal and interest, are reasonably assured.
A specific allowance is assigned to the loan for the amount of estimated credit loss. Individually evaluated loans are charged-off, in whole or in part, when management believes that the recorded investment in the loan is uncollectible.

ACL for Loans Methodology

In accordance with ASC "Financial Instruments—Credit Losses (Topic 326)," the CECL methodology requires early recognition of credit losses using a lifetime credit loss measurement approach that also requires the consideration of reasonable and supportable forecasts in the estimate. The CECL methodology is applicable to the loan portfolio, measured at amortized cost. It also applies to off-balance sheet credit exposures such as unadvanced loan & line balances, commitments to originate loans, standby letters of credit, and other similar instruments, which are not unconditionally cancellable. Additionally, the Company has elected to continue to present the accrued interest receivable balance on loans separate from amortized costs, exclude accrued interest from the measurement of the allowance for credit losses for loans and to continue to write-off uncollectible accrued interest receivable by reversing interest income.

The ACL for loans is established through a provision for credit losses, recorded as a direct charge to earnings. The ACL for loans is a valuation account that is deducted from the amortized cost to present the net amount of the loan portfolio expected to be collected. Credit losses are charged against the ACL for loans when management believes that the collectability of the amortized cost of a loan's principal balance is unlikely. Recoveries on loans previously charged-off are credited to the ACL for loans, generally at the time cash is received on a charged-off account.

Arriving at an appropriate level of ACL for loans involves a high degree of management judgement. The underlying assumptions, estimates and assessments used to estimate the ACL for loans reflects the Company’s best estimate of model assumptions and forecasted conditions at that time. Changes in such estimates can significantly affect the ACL for loans and the provision for credit losses. 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. It is possible and likely that the Company will experience credit losses that are different from the current estimates and future additions to the ACL for loans may be necessary. 

On a quarterly basis, the Company makes an assessment to estimate the ACL for loans necessary to cover expected lifetime credit losses. The adequacy of the ACL for loans is reviewed and evaluated on a regular basis by an internal management committee, a sub-committee of the Company's Board of Directors (the "Board") and the full Board.

In making its assessment on the adequacy of the ACL for loans, management considers several quantitative and qualitative factors from internal and external sources relating to past events, current conditions, and reasonable and supportable forecasts.
The Company uses a systematic methodology to measure the amount of estimated loan losses. The methodology uses a two-tiered approach that applies general reserves for larger groups of homogeneous loans, segmented by loan type and specific reserves for loans individually evaluated.

Loans collectively evaluated

Management segments loans of similar risk characteristics using the Open Pool method by first calculating each segment's loss rate as net charge-offs over the expected average life of each segment, divided by the average loan balance over that same period. The historic loss factor is an average of the loss rate over a 5-year look-back period, which approximates the average age of charged-off loans. These historic loss factors are then adjusted up or down based on management's assessment of quantitative and qualitative factors. These key factors including quantitative facts about the loan portfolio such as: commercial concentrations by industry, property type and real estate location; the growth and composition of the loan portfolio; trends in risk classification of individual loans and higher risk problem assets; the level of delinquent, non-performing, and individually evaluated loans; the level of hardship loan modifications; foreclosure activity; net charge-offs; as well as trends in the general levels of these indicators. In addition, management monitors qualitative factors such as: expansion in the Company's geographic market area; the experience level of lenders and any changes in underwriting criteria; Market conditions, including general conditions in the multi-family, commercial real estate and construction and development markets in the Company's local region as well as changes in current and forecasted economic conditions, such as changes in gross domestic product, the unemployment rate and new jobs created, real estate values, commercial vacancy rates, recession risk estimates and other
relevant economic factors. Management uses a two-year reasonable and supportable forecast, and for periods beyond the forecast period, reverts immediately to historical loss rates. Management weighs the current effect of each of these areas on each particular loan segment in determining the allowance allocation factors. Management must exercise significant judgment when evaluating the effect of these quantitative and qualitative factors on the amount of the ACL for loans as data may not be reasonably available or directly applicable to determine the precise impact of a factor on the collectability over the remaining average life. The methodology contemplates a range of acceptable levels for these factors due to the subjective nature of the factors and the qualitative considerations related to the credit risk in the portfolio.

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, 2023.

Management recognizes that additional issues may also impact the estimate of expected credit losses to some degree. From time to time management will re-evaluate the qualitative factors, regulatory guidance, and industry data in use in order to consider the impact of other issues which, based on changing circumstances, may become more significant in the future.

Loans individually evaluated

For loans that are individually evaluated, as discussed above, management estimates the credit loss by comparing the loan's carrying value against either (i) the present value of the expected future cash flows discounted at the loan's effective interest-rate; (ii) the loan's observable market price; or (iii) the expected realizable fair value of the collateral, in the case of collateral dependent loans. A specific allowance is assigned to the loan for the amount of estimated credit loss. Individually evaluated loans are charged-off, in whole or in part, when management believes that the recorded investment in the loan is uncollectible.

Reserve for unfunded commitments

The reserve for unfunded commitments is included in the line item "Accrued expenses and other liabilities" on the Company’s Consolidated Balance Sheets. Management applies the CECL methodology to off-balance sheet commitments in a manner consistent with on-balance sheet loan loss rates. Additionally, the estimate of credit loss incorporates assumptions for both the likelihood and amount of funding over the estimated life of the commitments. Management periodically reviews and updates its assumptions for estimated funding rates.

(k) Other Real Estate Owned
 
Real estate acquired by the Company through foreclosure proceedings or the acceptance of a deed in lieu of foreclosure is classified as OREO. When property is acquired, it is recorded at the estimated fair value of the property acquired, less estimated costs to sell, establishing a new cost basis and carried on the Consolidated Balance Sheet in the line item "Prepaid expenses and other assets." The estimated fair value is based on market appraisals and the Company's internal analysis. Any loan balance more than the estimated realizable fair value on the date of transfer is charged to the allowance for credit losses on that date. All costs incurred thereafter in maintaining the property, as well as subsequent declines in fair value are charged to non-interest expense.
 
(l) Premises and Equipment

Land is carried at cost. All other premises and equipment costs are stated at cost less accumulated depreciation and amortization. Depreciation or amortization is computed on a straight-line basis over the lesser of the estimated useful lives of the asset or the respective lease term (including renewal options reasonably certain to be exercised) for leasehold improvements generally as follows:

Bank premises, land improvements and leasehold improvements
10 to 39 years
Computer software and equipment
3 to 5 years
Furniture, fixtures and equipment
3 to 10 years

(m) Leases

The Company leases office space, space for ATM locations and certain branch locations under noncancellable operating leases,
several of which have renewal options to extend lease terms. Upon commencement of a new lease, the Company will recognize a ROU asset and corresponding lease liability on the Consolidated Balance Sheet for all leases with terms longer than 12 months. The lease liability represents the present value of the future lease payments while the ROU asset represents the lease liability plus any lease prepayments and initial direct costs.

The Company’s operating lease agreements contain both lease and non-lease components (such as common area maintenance), which are generally accounted for separately. To calculate the lease liability, the Company uses its incremental borrowing rate as the discount rate to determine the net present value of the lease liability. In determining the term of a lease, the Company included option renewal periods that it considered reasonably certain to be exercised.

The Company recognizes lease expense on a straight-line basis in the "Occupancy and equipment expenses" line item within the non-interest expense section of the Consolidated Statement of Income.
(n) Bank Owned Life Insurance
 
The Company owns BOLI on certain current and former senior and executive officers, utilizing the tax-exempt earnings on BOLI to offset the cost of the Company's benefit plans. The cash surrender value of these policies is included as an asset on the Consolidated Balance Sheet, and any increases in cash surrender value are recorded as income on bank owned life insurance on the Consolidated Statement of Income.

(o) Impairment of Long-Lived Assets Other than Goodwill
 
The Company reviews long-lived assets, including premises, equipment, and lease right of use assets for impairment on an ongoing basis or whenever events or changes in business circumstances indicate that the remaining useful life may warrant revision or that the carrying amount of the long-lived asset may not be fully recoverable. If impairment is determined to exist, any related impairment loss is recognized through a charge to earnings. Impairment losses on assets disposed of, if any, are based on the estimated proceeds to be received, less cost of disposal.

(p) Goodwill
 
Goodwill is carried on the Company's consolidated financial statements and is related to the Company's acquisition of two branch offices in July 2000.

In accordance with GAAP, the Company does not amortize goodwill and instead, at least annually, evaluates whether the carrying value of goodwill has become impaired. A determination that goodwill has become impaired results in an immediate write-down of goodwill to its determined value with a resulting charge to the Company's Consolidated Statement of Income. Goodwill is evaluated at the reporting unit level. In the case of the Company, the services offered through the Bank and subsidiaries are managed as one strategic unit and represent the Company’s only reportable operating segment.
The Company has the option to perform either (i) a qualitative assessment of whether it is "more likely than not" that the reporting unit's fair value is less than its book value, or (ii) a quantitative assessment.

1.Management's qualitative assessment would take into consideration, among other items, macroeconomic conditions, industry and market considerations, cost or margin factors, financial performance and share price. Based on the qualitative assessment, if the Company were to conclude: a) it is "more likely than not" that the fair value of a reporting unit exceeds its book value, goodwill is deemed not impaired, or b) it is "more likely than not" that the fair value of a reporting unit is less than its book value, a quantitative goodwill analysis must be performed.

2.The Company may elect to forgo the qualitative assessment and perform the quantitative analysis even if management believes that is "more likely than not" that goodwill is not impaired. The quantitative goodwill analysis compares the fair value of the reporting unit with its book value, including goodwill. If the fair value of the reporting unit equals or exceeds its book value, goodwill is deemed not impaired. If the book value of the reporting unit exceeds its fair value, a goodwill impairment loss is recognized for the difference between these amounts, not exceeding the goodwill carrying amount.

At December 31, 2024, based on the Company's quantitative analysis, goodwill was deemed not impaired.
(q) Wealth Assets Under Management and Administration
 
Wealth assets under management consist of assets managed through Enterprise Wealth Management and Enterprise Wealth Services. Wealth assets under administration consist of 401(k) plans, trust, and custodial accounts. Wealth assets under management and administration are not included in the Consolidated Balance Sheets because they are not assets of the Company.

(r) Derivatives and Hedging
 
The Company records all derivatives on the balance sheet at fair value. Asset derivatives are included in the line item "Prepaid expenses and other assets," and liability derivatives are included in the "Accrued expenses and other liabilities" line item on the Consolidated Balance Sheets.

The accounting for changes in the fair value of derivatives depends on the intended use of the derivative. On the date the derivative instrument is entered into, the Company designates whether the derivative is part of a hedging relationship (i.e., cash flow or fair value hedge). The Company also assesses, both at the hedge’s inception and on an ongoing basis, whether the derivatives used in hedging transactions are highly effective in offsetting the changes in cash flows or fair values of hedged items.

Fair value hedges are considered a hedge of the exposure to changes in the fair value of an asset, liability or firm commitment attributable to a particular risk, such as interest rate risk. For derivatives designated and qualifying as fair value hedges, changes in the fair value are recognized in earnings.

Cash flow hedges are considered a hedge of the exposure to the variability in expected future cash flows, or other types of forecasted transactions. For derivatives designated and qualifying as cash flow hedges, changes in the fair value of derivative instruments that are highly effective are recorded in other comprehensive income (loss), net of tax and subsequently reclassified into earnings in the same period during which the hedged transaction affects earnings. Any hedge ineffectiveness is recognized directly in earnings.

For derivative instruments not designated as hedging instruments, such as back-to-back interest rate swaps and risk participation agreements, changes in fair value are recognized in earnings.

See Note 9, "Derivatives and Hedging Activities," to the Company's consolidated financial statements of this Form 10-K, contained below, for further information on the Company's derivative and hedging activities.
(s) Revenue Recognition

Interest and dividend income (primarily loan interest income from customers) are our primary sources of revenue and are outside of the scope of ASC 606, "Revenue from Contracts with Customers," and are accounted for under other ASC topics. The core principles of this standard require an entity to recognize revenue on the transfer of goods and services to customers as performance obligations are satisfied.

The primary areas of income for the Company within the scope of ASC 606 are wealth management fees and deposit and interchange fees which are components of non-interest income on the Company's Consolidated Statements of Income and are discussed below.

Wealth management fees consist of income generated through our wealth management services. Wealth management income is generated primarily by managing customers' financial assets. Revenue is recognized as our performance obligation is completed each month. Revenue earned through our wealth services platform is generated through a third-party arrangement to refer, manage and service customers. For new sales and referrals along with transactional type charges, the performance obligation is based on a point in time and the payment is received and revenue is recognized in the same month as the revenue generating activity. For managing and servicing customers, revenue is recognized when our performance obligation is completed each month.

Deposit and interchange fees are comprised of deposit account related charges and income generated from electronic payment interchanges. Deposit account charges consist of certain transactional analysis fees net of earning balance credits, monthly account service fees, and transactional fees such as overdraft fees. Analysis and monthly account services fees are recognized
over the period the service is performed. For transactional fees, the performance obligation and the revenue are recognized at a point of time and payment is typically received as the service is rendered. Interchange income is generated primarily from retail debit card transactions processed through the card payment network. The performance obligation and the revenue are recognized when the service is performed.

The following non-interest income components are not subject to ASC 606: income on BOLI, net gains/losses on investment securities, and net gains on sales of loans, and are covered under other ASC topics. The remaining revenue items in non-interest income are not material.

(t) Stock-Based Compensation
 
The Company currently has one active stock incentive plan: The Enterprise Bancorp, Inc. 2016 Stock Incentive Plan, as amended (the "2016 Plan"). The 2016 Plan permits the Board to grant, under various terms, both incentive and non-qualified stock options (for the purchase of newly issued shares of common stock), restricted stock, restricted stock units and stock appreciation rights to officers and other employees, and to non-employee directors and consultants. The 2016 Plan also allows for newly issued shares of common stock to be issued without restrictions to officers and other employees, and non-employee directors and consultants.

As of December 31, 2024, 270,474 common shares remained available for future grants under the 2016 Plan. Awards previously granted under an earlier, now expired plan remain outstanding and may be exercised through 2028.

Under terms of the 2016 Plan, options exercised and restricted stock awards vested may be net settled to cover payment for option costs and employee tax obligations, resulting in shares of common stock being reacquired by the Company and returned to the pool of shares reserved for issuance under the incentive plans. In accordance with Massachusetts law, shares reacquired by the Company will be treated as authorized but unissued shares.

The non-employee members of the Company's Board may opt to receive newly issued shares of the Company's common stock in lieu of cash compensation for attendance at Board and Board Committee meetings. These shares are issued annually each January for Board meetings held in the previous year. Directors must make an irrevocable election to receive shares of common stock in lieu of cash fees prior to December 31st of the preceding year. Directors are granted shares of common stock in lieu of cash fees based on an average quarterly close price of the Company's common stock on the NASDAQ Global Market during the year.

From time to time, the Company issues shares to community members for consulting on regional advisory councils and grants shares of fully vested stock as employee anniversary awards. These shares vest immediately and the cost, which is based on the market price on the date of the grant and deemed to be immaterial, is expensed in the period in which the services are rendered.

The Company's consolidated financial statements include stock-based compensation expense for the portion of stock option awards and stock awards for which the requisite service has been rendered during the period or the estimate of achieving certain predefined performance objectives. The compensation expense has been recorded based on the estimated grant-date fair value of the stock option awards with no adjustment for estimated forfeitures, or in the case of stock awards, the market value of the common stock on the date of grant. Expense adjustments are made for actual forfeitures as they occur.

The Company will recognize the remaining estimated compensation expense for the portion of outstanding awards and compensation expense for any future awards, net of actual forfeitures, as the requisite service is rendered (i.e., on a straight-line basis over the remaining vesting period of each award) or as performance objectives are met. Stock awards that do not require future service ("vested awards") will be expensed immediately. Stock-based compensation also includes director stock compensation for stock awards and stock in lieu of cash fees, both included in other operating expenses.

See Note 14, "Stock-Based Compensation," to the Company's consolidated financial statements of this Form 10-K, contained below, for further information on the Company's stock incentive plans and terms of outstanding awards and the Company's stock-based compensation.

(u) Income Taxes
 
The Company and its subsidiaries file income tax returns in the U.S. federal jurisdiction and various states, within the directives of the respective enacted tax legislation. The Company uses the asset and liability method of accounting for income taxes.
Under this method, deferred tax assets and liabilities are recognized for the future tax expense or benefit attributable to differences between the financial statement carrying amounts and the tax basis of assets and liabilities. The deferred tax assets and liabilities are reflected at currently enacted income tax rates applicable to the period in which the deferred tax assets or liabilities are expected to be realized or settled. As changes in tax laws or rates are enacted, deferred tax assets and liabilities will be adjusted accordingly through the provision for income taxes in the period that includes the enactment date, which may be earlier than the effective date.

The Company's policy is to classify interest resulting from underpayment of income taxes as income tax expense in the first period the interest would begin accruing according to the provisions of the relevant tax law. The Company classifies penalties resulting from underpayment of income taxes as income tax expense in the period for which the Company claims or expects to claim an uncertain tax position or in the period in which the Company's judgment changes regarding an uncertain tax position.

The income tax provisions will differ from the expense that would result from applying the federal statutory rate to income before taxes, due primarily to the impact of state tax expense, tax-exempt interest from certain investment securities, loans and BOLI and the tax impact from equity compensation activity.

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.

As of December 31, 2024, the Company had one investment in a local NMTC project which provides federal tax incentives for investments in distressed communities. The investment is accounted for using the proportional amortization method and will be amortized over seven years, which represents the period that the tax credits and other tax benefits will be utilized.

(v) Earnings per Share
 
Basic earnings per share are calculated by dividing net income available to common shareholders by the weighted average number of common shares outstanding (including participating securities) during the year. The Company's only participating securities are unvested restricted stock awards that contain non-forfeitable rights to dividends. Diluted earnings per share reflects the effect on weighted average shares outstanding of the number of additional shares outstanding if dilutive stock options were converted into common stock using the treasury stock method.

(w) Reporting Comprehensive Income

Comprehensive income is defined as all changes to shareholders' equity except investments by and distributions to shareholders. Net income is one component of comprehensive income, with other components referred to in the aggregate as other comprehensive income. The Company's other comprehensive income components are the changes in fair value of debt securities and cash flow hedges, both net of income taxes. Pursuant to GAAP, the Company initially excludes the unrealized holding gains and losses from net income; however, they are later reported as reclassifications out of accumulated other comprehensive income into net income when circumstances warrant.

When debt securities are sold, the reclassification of realized gains and losses on available-for-sale securities are included on the Consolidated Statements of Income under the "Non-interest income" subheading on the line item "Net gains (losses) on sales of available-for-sale debt securities" and the related income tax expense is included in the line item "Provision for income taxes."

For cash flow hedges of interest rate risk, the change in fair value will be reclassified in the same period during which the hedged transaction affects earnings, to either interest expense as interest is incurred on the Company's hedge liability, or to interest income as interest is earned on the Company's hedge asset. The reclassification of gain or loss on the derivatives are included on the Consolidated Statements of Income under "Interest income" or "Interest expense" line item and the related income tax expense is included in the line item "Provision for income taxes," both of which are also detailed, along with other information, in Note 11, "Comprehensive Income (Loss)," of this Form 10-K.

(x) Dividends

Neither the Company nor the Bank may declare or pay dividends on its stock if the effect thereof would cause shareholders'
equity to be reduced below applicable regulatory capital requirements or if such declaration and payment would otherwise violate regulatory requirements.

As the principal asset of the Company, the Bank currently provides the only source of cash for the payment of dividends by the Company. Under Massachusetts law, trust companies such as the Bank may pay dividends only out of "net profits" and only to the extent that such payments will not impair the Bank's capital stock. Any dividend payment that would exceed the total of the Bank's net profits for the current year plus its retained net profits of the preceding two years would require the Massachusetts Division of Banks' approval. Applicable provisions of the FDIC Improvement Act also prohibit a bank from paying any dividends on its capital stock if the bank is in default on the payment of any assessment to the FDIC or if the payment of dividends would otherwise cause the bank to become "undercapitalized." Any restrictions, regulatory or otherwise, on the ability of the Bank to pay dividends to the Company may restrict the ability of the Company to pay dividends to the holders of its common stock.

The statutory term "net profits" essentially equates with the accounting term "net income" and is defined under the Massachusetts banking statutes to mean the remainder of all earnings from current operations plus actual recoveries on loans and investments and other assets after deducting from such total all current operating expenses, actual losses, accrued dividends on any preferred stock and all federal and state taxes.

In addition, the Company maintains a dividend reinvestment and direct stock purchase plan which enables shareholders, at their discretion, to elect to reinvest cash dividends paid on their shares of the Company's common stock by purchasing additional shares of common stock from the Company at a purchase price equal to fair market value. Under the DRSPP, shareholders and new investors also have the opportunity to purchase shares of the Company's common stock without brokerage fees, subject to monthly minimums and maximums. Effective December 9, 2024, all share purchases under the DRSPP were suspended as
a result of the pending merger with Independent.

ASU 2023-09 is effective for fiscal years, and interim periods within those fiscal years beginning after December 15, 2024, with early adoption permitted. ASU 2023-09 is not expected to have a material impact on our consolidated financial statements.
In in November 2024, the FASB issued ASU 2024-03, "Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures." This ASU requires disclosure, in the notes to financial statements, of specified information about certain costs and expenses for both interim and annual reporting periods. This standard is effective for annual periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. Early adoption is permitted.

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 $2.7 million and $3.1 million at December 31, 2024 and 2023, respectively.

At December 31, 2024, management performed its quarterly analysis of all securities with unrealized losses and concluded that the unrealized losses resulted from significant increases in market interest rates relative to the book yield on the securities held. Management concluded that no ACL for available-for-sale securities was necessary as of December 31, 2024 and anticipates they will mature or be called at par value. The Company does not intend to sell these investments and has determined, based upon available evidence, that it is more likely than not that the Company will not be required to sell each security before the recovery of its amortized cost basis.
The following tables summarize the duration of unrealized losses for debt securities at December 31, 2024 and 2023:

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 $128.4 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 FRB. The fair value of debt securities pledged as collateral for these purposes was $575.2 million and $650.8 million at December 31, 2024 and 2023, respectively.

(1)The loan balances in the table above include loans designated as non-accrual despite their payment due status. Loans designated as non-accrual are presented below.

At December 31, 2024 and December 31, 2023, all loans past due 90 days or more were carried as non-accrual, however, not all non-accrual loans were 90 days or more past due in their payments. Loans that were less than 90 days past due where reasonable doubt existed as to the full and timely collection of interest or principal have also been designated as non-accrual, despite their payment due status.
The following tables present the amortized cost of loans designated as non-accrual, despite their payment status, by portfolio classification as of the dates indicated:

Collateral dependent loans

The total recorded investment in collateral dependent loans amounted to $26.9 million at December 31, 2024, compared to $13.7 million at December 31, 2023. Total accruing collateral dependent loans amounted to $438 thousand, while non-accrual collateral dependent loans amounted to $26.5 million as of December 31, 2024. As of December 31, 2023, total accruing collateral dependent loans amounted to $2.4 million, while non-accrual collateral dependent loans amounted to $11.3 million.
Loans that have been individually evaluated and repayment is expected substantially from the operations or ultimate sale of the underlying collateral are deemed to be collateral dependent loans. Collateral dependent loans are adversely classified loans. These loans may be accruing or on non-accrual status. Collateral dependent loans are carried at the lower of the recorded investment in the loan or the estimated fair value. Underlying collateral will vary by type of loan, as discussed below.

Commercial real estate loans include loans secured by both owner and non-owner occupied (investor) real estate. These loans are typically secured by a variety of commercial, residential investment, and industrial property types, including one-to-four and multi-family apartment buildings, office, industrial, or mixed-use facilities, strip shopping centers, or other commercial properties.

Commercial and industrial credits may be unsecured loans and lines to financially strong borrowers, loans secured in whole or in part by real estate unrelated to the principal purpose of the loan or secured by inventories, equipment, or receivables.

Commercial construction loans include the development of residential housing and condominium projects, the development of commercial and industrial use property, and loans for the purchase and improvement of raw land. These loans are secured in whole or in part by underlying real estate collateral.

Residential mortgage loans and home equity lines may be secured by one-to-four family residential properties serving as the borrower's primary residence, or as vacation homes or investment properties.

Consumer loans consist primarily of secured or unsecured personal loans, loans under energy efficiency financing programs in conjunction with Massachusetts public utilities, and overdraft protection lines on checking accounts.
Management does not set any minimum delay of payments as a factor in reviewing for individual evaluation. Management considers the individual payment status, net worth and earnings potential of the borrower, and the value and cash flow of the collateral as factors to determine if a loan will be paid in accordance with its contractual terms.

The following tables present the recorded investment in collateral dependent individually evaluated loans and the related specific allowance by portfolio allocation as of the dates indicated:

Leases Leases
For the Company, material leases consist of operating leases on our facilities, mainly branch leases; leases 12 months or less and immaterial equipment leases have been excluded.

As of December 31, 2024, the Company had 16 active operating real estate leases. The Company's leased facilities are contracted under various non-cancelable operating leases, most of which provide options to the Company to extend the lease periods and include periodic rent adjustments. While the Company typically exercises its option to extend lease terms, the lease contains provisions that allow the Company, upon notification, to terminate the lease at the end of the lease term, or any option period. Several real estate leases also provide the Company the right of first refusal should the property be offered for sale.

Lease expenses for the year ended December 31, 2024 amounted to $1.7 million, compared to $1.6 million for both of the years ended December 31, 2023 and 2022. Variable lease costs and short-term lease expenses included in lease expense during these periods were immaterial.

The weighted average remaining lease term for operating leases at December 31, 2024 and 2023 was 27.6 years and 28.4 years, respectively. The weighted average discount rate was 3.55% at both December 31, 2024 and 2023.

At December 31, 2024, the remaining undiscounted cash flows by year of these lease liabilities were as follows:

As a member of the FHLB, the Bank has the potential capacity to borrow an amount up to the value of its discounted qualified collateral. Borrowings from the FHLB are secured by certain securities from the Company's investment portfolio not otherwise pledged and certain residential and commercial real estate loans. At December 31, 2024, based on qualifying collateral minus outstanding advances, the Bank had the capacity to borrow additional funds from the FHLB of up to approximately $670.0 million. In addition, based on qualifying corporate and municipal bond collateral, the Bank had the capacity to borrow funds from the FRB up to approximately $300.0 million at December 31, 2024. The Bank also has pre-approved borrowing arrangements with large correspondent banks to provide overnight and short-term borrowing capacity.

The Company had outstanding subordinated debt, net of deferred issuance costs, of $59.8 million, and $59.5 million at December 31, 2024, and December 31, 2023, respectively. The debt consists of fixed-to-floating rate notes due in 2030 and callable at the Company's option on or after July 15, 2025. The subordinated notes are intended to qualify as Tier 2 capital for regulatory purposes.

The subordinated notes pay interest at a fixed rate of 5.25% per annum through July 15, 2025, after which floating quarterly rates apply. Original debt issuance costs were $1.2 million and have been netted against the subordinated debt on the consolidated balance sheet in accordance with accounting guidance. These costs are being amortized to interest expense over the life of the subordinated notes.

Derivatives designated as hedging instruments

Interest-rate positions

The Company may utilize various interest rate derivatives as hedging instruments against interest rate risk associated with the Company’s loan portfolio. Each interest rate swap agreement was designated as a fair value hedge and involves 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. At December 31, 2024 and December 31, 2023, the Company had three pay fixed, receive float, interest rate swap agreements with a combined notional value of $100.0 million.

Customer related positions

The Company has a "Back-to-Back Swap" program whereby the Bank enters into an interest-rate swap with qualified commercial banking customers and simultaneously enters into equal and opposite interest-rate swap with a swap counterparty. The customer interest-rate swap agreement allows commercial banking customers to convert a floating-rate loan payment to a fixed-rate payment.

Each Back-to-Back swap consists of two interest-rate swaps (a customer swap and offsetting counterparty swap) and amounted to a total number of two interest-rate swaps outstanding at December 31, 2024 and four outstanding at December 31, 2023. As a result of this offsetting relationship, there were no net gains or losses recognized in income on Back-to-Back swaps during the years ended December 31, 2024, 2023, or 2022.

Interest-rate swaps with the counterparty are subject to master netting agreements, while interest-rate swaps with customers are not. At December 31, 2024 and December 31, 2023, all the 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.
The Company enters into 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-related Contingent Features

By using derivative financial instruments, the Company exposes itself to counterparty credit risk. Credit risk is the risk of failure by the counterparty to perform under the terms of the derivative contract. The credit risk in derivative instruments is mitigated by entering into transactions with highly rated counterparties that management believes to be creditworthy. As of December 31, 2024, the Company had two active interest-rate swap institutional counterparties both of which had investment grade credit ratings.

The Company's interest-rate swaps with counterparties contain credit-risk-related contingent provisions. These provisions provide the counterparty with the right to terminate its derivative positions and require the Company to settle its obligations under the agreements if the Company defaults on certain of its indebtedness.

As of December 31, 2024 and December 31, 2023, the Company had credit risk exposure relating to interest-rate swaps with counterparties of $321 thousand and $492 thousand, respectively, and cash posted by counterparties amounted to $120 thousand and $590 thousand at December 31, 2024 and December 31, 2023, respectively.

The Company has minimum collateral posting thresholds with certain of its derivative counterparties, and as of December 31, 2024 and December 31, 2023, cash collateral posted by the Company amounted to $480 thousand and $570 thousand, respectively.

As of December 31, 2024, the fair value of derivatives related to these agreements was at a net liability position of $11 thousand, which excludes any adjustment for nonperformance risk.

Other Derivative Related Activity
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 December 31, 2024 and December 31, 2023, the estimated fair value of the Company's interest-rate lock commitments and commitments to sell these mortgage loans were deemed immaterial.

Commitments and Contingencies Disclosure [Abstract]  
Commitments, Contingencies and Financial Instruments with Off-Balance Sheet Risk and Concentrations of Credit Risk Commitments, Contingencies and Financial Instruments with Off-Balance Sheet Risk and Concentrations of Credit Risk
The Company is party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to originate loans, letters of credit, and unadvanced portions of loans and lines of credit.

The instruments involve, to varying degrees, elements of credit risk in excess of the amount recognized in the Consolidated Balance Sheets. The contractual amounts of these instruments reflect the extent of involvement the Company has in the particular classes of financial instruments.

The Company's exposure to credit loss in the event of nonperformance by the other party to the financial instrument for loan commitments and letters of credit is represented by the contractual amounts of those instruments. The Company uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments.

Financial instruments with off-balance sheet credit risk at December 31, 2024 and 2023 are as follows:
(Dollars in thousands)20242023
Commitments to originate loans$35,327 $41,326 
Commitments to originate residential mortgages loans for sale1,008 —

Unadvanced portions of home equity lines163,515 156,216 
Unadvanced portions of consumer loans3,503 3,679 

Commitments to originate loans are agreements to lend to a customer provided there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee by the customer. Since some of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Company evaluates each customer's credit worthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Company upon extension of credit, is based on management’s credit evaluation of the borrower. 

The Company originates residential mortgage loans intended for sale under agreements to sell such loans on an individual loan basis and may retain or sell the servicing when selling the loans. Loans sold are subject to standard secondary market underwriting and eligibility representations and warranties over the life of the loan and are subject to an early payment default period covering the first four payments for certain loan sales.

Letters of credit are conditional commitments issued by the Company to guarantee the financial obligation or performance of a customer to a third-party. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers. If the letter of credit is drawn upon, a loan is created for the customer, generally a commercial loan, with the same criteria associated with similar commercial loans.

Unadvanced portions of loans and lines of credit represent credit extended to customers but not yet drawn upon and are secured or guaranteed under preexisting loan agreements and credit evaluations having taken into consideration the full commitment amount.

See also Note 9, "Derivatives and Hedging Activities," and Note 1, "Summary of Significant Accounting Policies," under Item (r), "Derivatives," to the Company's consolidated financial statements of this Form 10-K, contained above, for information on the Company's interest-rate lock commitments, interest-rate swaps, and participation in loans originated by third-party banks with potential contingent liabilities.
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 and 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 consolidated financial condition or results of operations of the Company.

Shareholders' Equity Shareholders' Equity
Shares Authorized and Share Issuance

The Company's authorized capital is divided into common stock and preferred stock. The Company is authorized to issue 40,000,000 shares of common stock, with a par value of $0.01 per share, and as of December 31, 2024, shares issued and outstanding amounted to 12,447,308. Holders of common stock are entitled to one vote per share and are entitled to receive dividends if, as and when declared by the Board. Dividend and liquidation rights of the common stock may be subject to the rights of any outstanding preferred stock. The Company is also authorized to issue 1,000,000 shares of preferred stock, with a par value of $0.01 per share. No preferred stock has been issued as of the date of this Form 10-K.

The Company previously had a shareholders' rights plan pursuant to which each share of Company common stock included a right to purchase under certain circumstances a fraction of a share of the Company's Series A Junior Participating Preferred Stock, par value $0.01 per share. In December 2024, the Company amended its shareholders' rights plan to provide for the expiration of such rights on December 7, 2024, effectively terminating the plan.

The Company's stock incentive plans permit the Board to grant, under various terms, stock options (for the purchase of newly issued shares of common stock), common stock, restricted stock awards, restricted stock units and stock appreciation rights to officers and other employees, non-employee directors and consultants. See Note 14, "Stock-Based Compensation," to the Company's consolidated financial statements of this Form 10-K, contained below, for additional information regarding the Company's stock incentive plans.
Capital

Capital planning by the Company and the Bank considers current needs and anticipated future growth. Ongoing sources of capital include the retention of earnings, less dividends paid, proceeds from the exercise of employee stock options and proceeds from purchases of shares pursuant to the DRSPP. Additional sources of capital for the Company and the Bank have been proceeds from the issuance of common stock and proceeds from the issuance of subordinated debt. The Company believes its current capital is adequate to support ongoing operations.

Management believes, as of December 31, 2024, that the Company and the Bank met all capital adequacy requirements to which they were subject. As of December 31, 2024 and December 31, 2023, the Company met the definition of "well-capitalized" under the applicable Federal Reserve Board regulations and the Bank qualified as "well-capitalized" under the prompt corrective action regulations of Basel III and the FDIC.

(1)    Before application of the capital conservation buffer of 2.50%. See discussion below.
(2)    For the Bank to qualify as "well-capitalized," it must maintain at least the minimum ratios listed under the regulatory prompt corrective action framework. This framework does not apply to the Company.
The Company is subject to the Basel III capital ratio requirements, which include a "capital conservation buffer" of 2.50% above the regulatory minimum risk-based capital adequacy requirements shown above. If a banking organization dips into its capital conservation buffer it may be restricted in its activities, including its ability to pay dividends and discretionary bonus payments to its executive officers. Both the Company's and the Bank's actual ratios, as outlined in the table above, exceeded the Basel III risk-based capital requirement with the capital conservation buffer as of December 31, 2024.

The Basel III minimum capital ratio requirements as applicable to the Company and the Bank with the capital conservation buffer are summarized in the table below:

Failure to meet minimum capital requirements can initiate or result in certain mandatory and possibly additional discretionary supervisory actions by regulators that, if undertaken, could have a material adverse effect on the Company's consolidated financial statements. Under applicable capital adequacy requirements and the regulatory framework for prompt corrective action applicable to the Bank, the Company must meet specific capital guidelines that involve quantitative measures of the Company's assets, liabilities, and certain off-balance sheet items as calculated under regulatory accounting practices. The Company's capital amounts and classifications are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors.

See also "Supervision and Regulation," contained in Item 1, "Business," of this Form 10-K for further information on the Company's Basel III and capital requirements.

Dividends

For the year ended December 31, 2024, the Company declared $11.9 million in cash dividends and shareholders utilized the dividend reinvestment portion of the DRSPP to purchase an aggregate of 54,698 shares of the Company's common stock totaling $1.6 million. For the year ended December 31, 2023, the Company declared $11.2 million in cash dividends and shareholders utilized the dividend reinvestment portion of the DRSPP to purchase 50,443 shares of the Company's common stock totaling $1.5 million. For the year ended December 31, 2022, the Company declared $9.9 million in cash dividends and shareholders utilized the dividend reinvestment portion of the DRSPP to purchase 40,640 shares of the Company's common stock totaling $1.4 million.

Employee Benefit Plans

Retirement Benefits [Abstract]  
Employee Benefit Plans Employee Benefit Plans
 
Defined Contribution Plans
 
The Company has a 401(k) defined contribution employee benefit plan. The 401(k) plan allows eligible employees to contribute a percentage of their earnings to the plan. A portion of an employee's contribution, as determined by the Compensation and Human Resources Committee of the Board of Directors, is matched by the Company. During the years ended December 31, 2024, 2023 and 2022 the Company's percentage match was 70% up to the first 6% contributed by the employee.
 
All eligible employees, at least 18 years of age and completing 1 hour of service, may participate in the 401(k) plan. Vesting for the Company's 401(k) retirement plan matching contribution is based on years of service with participants becoming 25% vested on the anniversary of their hire date and each subsequent year until they are 100% vested following four years of service. Unvested amounts not distributed to an employee following termination of employment are used to offset plan expenses and the Company's matching contributions.
The Company's expense for the 401(k) plan match was $2.2 million, $2.1 million and $1.9 million for the years ended December 31, 2024, 2023 and 2022, respectively.

Additionally, the Company maintains the Enterprise Bank Supplemental Executive Retirement and Deferred Compensation Plan. The plan is unfunded and is maintained for the purpose of providing deferred compensation to a certain group of management employees. Total expenses for the deferred compensation plan were $149 thousand and $315 thousand for the years ended December 31, 2024 and 2023, respectively.

Supplemental Employee Retirement Plan

The Company has salary continuation agreements with two of its current executive officers and one former executive officer. These salary continuation agreements provide for predetermined fixed-cash supplemental retirement benefits to be provided for a period of 20 years after each individual reaches a defined "benefit age." The individuals covered under the SERP have reached the defined benefit age and are receiving payments under the SERP. Additionally, the Company has not recognized service costs in the current or prior year as each officer had previously attained their individually defined benefit age and was fully vested under the SERP.
 
This non-qualified plan represents a direct liability of the Company, and as such, the Company has no specific assets set aside to settle the benefit obligation. The aggregate amount accrued, or the "accumulated benefit obligation," is equal to the present value of the benefits to be provided to the employee or any beneficiary. Because the Company's benefit obligations provide for predetermined fixed-cash payments, the Company does not have any unrecognized costs to be included as a component of accumulated other comprehensive income.

The amounts charged to expense for the SERP are included in the table below. The Company anticipates accruing an additional $49 thousand to the SERP for the year ending December 31, 2025.

The following table provides a reconciliation of the changes in the supplemental retirement benefit obligation and the net periodic benefit cost for the years ended December 31:

Supplemental Life Insurance

The Company has provided supplemental life insurance benefits to certain executive and senior officers through split-dollar life insurance and a death benefit only plan. See Item (l), "Bank Owned Life Insurance," in Note 1, "Summary of Significant Accounting Policies," to the Company's consolidated financial statements of this Form 10-K, contained above, for further information regarding BOLI.

The split-dollar arrangements provide a death benefit to the officer's designated beneficiaries that extend to post-retirement periods and the Company has recognized a liability for post-retirement cost of insurance related to these plans. The employee benefit related to the death benefit only plans terminates when the employee is no longer employed by the Company.

These non-qualified plans represent a direct liability of the Company, and, as such, the Company has no specific assets set aside to settle the benefit obligation. The funded status of the split dollar plan represents the "accumulated post-retirement benefit obligation," which is the present value of the post-retirement cost of insurance associated with this arrangement."

Share-Based Payment Arrangement [Abstract]  
Stock-Based Compensation Stock-Based Compensation
 
The Company currently has one active stock incentive plan: The Enterprise Bancorp, Inc. 2016 Stock Incentive Plan, as amended.
The Company's stock-based compensation expense related to these plans includes stock options and stock awards to officers and other employees included in salary and benefits expense, and stock awards and stock compensation in lieu of cash fees to non-employee directors both included in other operating expenses.
Total stock-based compensation expense was $2.3 million for each of the years ended December 31, 2024, 2023 and 2022. The total tax benefit recognized related to the stock-based compensation expense was $649 thousand, $637 thousand, and $651 thousand for the years ended December 31, 2024, 2023 and 2022, respectively.
The Company recorded a tax expense associated with employee exercises and vesting of stock compensation amounting to $60 thousand for the year ended December 31, 2024 compared to a tax benefit of $108 thousand and $147 thousand for the years ended December 31, 2023, and 2022, respectively.

Stock Option Awards

Stock options granted generally vest 50% in year two and 50% in year four, on or about the anniversary date of the awards. Under the terms of the plans, stock options may not be granted at less than 100% of the fair market value of the shares on the date of grant and may not have a term of more than 10 years.
 
The Company utilizes the Black-Scholes option valuation model in order to determine the per share grant date fair value of stock option grants.

The Company issued no stock options during the year ended December 31, 2024 and December 31, 2023.
The expected volatility is the anticipated variability in the Company's share price over the expected life of the stock option and is based on the Company's historical volatility.
 
The expected dividend yield is the Company's projected dividends based on historical annualized dividend yield to coincide with volatility divided by its share price at the date of grant.

The expected life represents the period of time that the stock option is expected to be outstanding. The Company utilized the simplified method, under which the expected term equals the vesting term plus the contractual term divided by two.

The risk-free interest rate is based on the U.S. Department of the Treasury rate in effect at the time of grant for a period equivalent to the expected life of the stock option.

Stock option transactions during the year ended December 31, 2024 are summarized as follows:

The intrinsic value of stock options vested and exercisable represents the total pretax value that would have been received by the stock option holders had all in-the-money vested stock option holders exercised their options on December 31, 2024. At December 31, 2024, 112,802 of the vested and exercisable stock options were in-the money.

Cash received from stock option exercises amounted to $363 thousand, $180 thousand, and $118 thousand during the years ended December 31, 2024, 2023 and 2022, respectively. The total intrinsic value of stock options exercised amounted to $337 thousand, $563 thousand and $93 thousand during the years ended December 31, 2024, 2023 and 2022, respectively. Cash paid
by the Company for the net settlement of stock options to cover employee tax obligations amounted to $62 thousand, $153 thousand and $8 thousand during the years ended December 31, 2024, 2023 and 2022, respectively.

Stock option activity during the year ended December 31, 2024 for unvested options are summarized as follows:

The total fair value of stock options vested (based on grant date fair value) during the years ended December 31, 2024, 2023 and 2022 was $255 thousand, $204 thousand, and $186 thousand, respectively.

Compensation expense recognized in association with the stock option awards amounted to $130 thousand, $175 thousand and $206 thousand for the years ended December 31, 2024, 2023 and 2022, respectively. The total tax benefit recognized related to the stock option expense was $36 thousand, $49 thousand and $58 thousand for the years ended December 31, 2024, 2023 and 2022, respectively.
 
As of December 31, 2024, there was $64 thousand of unrecognized stock-based compensation expense related to non-vested stock options. That cost is expected to be recognized over the remaining weighted average vesting period of 1.1 years.

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 years indicated:

Total restricted stock awards122,042 73,904 53,224 
Weighted average grant date fair value$24.68 $32.04 $38.57 

The restricted stock awards allow for the non-forfeitable receipt of dividends, and the voting of all shares, whether or not vested, throughout the vesting periods at the same proportional level as common shares outstanding.

Upon vesting, restricted stock awards may be net settled to cover payment for employee tax obligations, resulting in shares of common stock being reacquired by the Company. During the years ended December 31, 2024, 2023 and 2022 the Company paid $347 thousand, $294 thousand and $425 thousand, respectively, to net settle the vesting of restricted stock awards to cover employee tax obligations.

Any shares that are returned to the Company prior to vesting or as payment for employee tax obligations upon vesting shall remain available for issuance under such plan, while the plan is still effective.
The following table sets forth a summary of the activity for the Company's restricted stock awards:

Stock-based compensation expense recognized in association with the restricted stock awards amounted to $2.0 million for the year ended December 31, 2024 and $1.9 million for both of the years ended December 31, 2023 and 2022. The total tax benefit recognized related to restricted stock award compensation expense was $559 thousand, $527 thousand and $522 thousand for the years ended December 31, 2024, 2023 and 2022, respectively.

As of December 31, 2024, there remained $3.1 million of unrecognized compensation expense related to the restricted stock awards. That cost is expected to be recognized over the remaining weighted average vesting period of 2.3 years.

The total fair value of restricted stock awards vested (based on grant date fair value) during the years ended December 31, 2024, 2023 and 2022 was $2.0 million, $1.6 million and $1.8 million, respectively.

Stock in Lieu of Directors' Fees

In addition to the restricted stock awards discussed above, non-employee members of the Company's Board may opt to receive newly issued shares of the Company's common in stock in lieu of cash compensation for attendance at Board and Board Committee meetings. These shares are valued based on the Company's average quarterly close price and are issued in January of the following year.

Stock in lieu of directors' fees expense was $190 thousand for the year ended December 31, 2024, which represented 6,515 shares issued in January of 2025, $218 thousand for the year ended December 31, 2023, which represented 7,224 shares issued in January of 2024, and $254 thousand for the year ended December 31, 2022, which represented 7,265 shares issued in January of 2023. The total tax benefit recognized related to the stock in lieu of directors' fees for meeting attendance was $54 thousand, $61 thousand and $71 thousand for the years ended December 31, 2024, 2023 and 2022, respectively.

Management believes based upon positive historical and expected future earnings that it is more likely than not the Company will generate sufficient taxable income to realize the deferred tax asset existing at December 31, 2024. However, factors beyond management's control, such as the general state of the economy, can affect future levels of taxable income and there can be no assurances that sufficient taxable income will be generated to fully realize the deferred tax assets in the future. 

The Company paid total estimated income taxes during the years ended December 31, 2024, 2023 and 2022 of $13.5 million, $15.6 million and $17.0 million, respectively.
The Company had no unrecognized tax benefits accrued as income tax liabilities or receivables or as deferred tax items at December 31, 2024, or December 31, 2023. The Company is generally subject to examinations by taxing authorities for the prior three tax years.

The Company invests in qualified affordable housing projects as a limited partner. As of December 31, 2024, and December 31, 2023, the Company recognized no Federal Low Income Housing tax credits. As of December 31, 2024 the Company had no remaining tax credits related to these Federal Low Income Housing Tax Credit program to be realized. For the year ended December 31, 2022, the Company recognized $36 thousand in Federal Low Income Housing tax credits.
In March 2023, the Bank made an equity contribution to its wholly owned subsidiary, the NMTC Investment Fund, in order to invest in a local NMTC project. The Bank invested $3.7 million in the Investment Fund and anticipates receiving $4.8 million of federal tax credits over seven years. The investment is accounted for using the proportional amortization method and will be amortized over seven years, which represents the period that the tax credits and other tax benefits will be utilized. 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 year ended December 31, 2024, the related amortization expense amounted to $478 thousand and the related tax credits amounted to $613 thousand.

There were 74,538, 61,425 and 34,291 stock options outstanding at December 31, 2024, 2023 and 2022, respectively, that were determined to be anti-dilutive and therefore excluded from the calculation of dilutive shares for the years ended December 31, 2024, 2023 and 2022. These stock options, which were not dilutive at that date, may potentially dilute earnings per share in the future.

The Company may issue stock options and restricted stock awards to officers and other employees and restricted stock awards and stock compensation in lieu of cash fees to non-employee directors. The restricted stock awards allow for the non-forfeitable receipt of dividends, and the voting of all shares, whether or not vested, throughout the vesting periods at the same proportional level as common shares outstanding. The unvested restricted stock awards are the Company's only participating securities and are included in shares outstanding. Unvested participating restricted awards amounted to 176,571 shares and 130,039 shares as of December 31, 2024 and December 31, 2023, 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 did not transfer any assets between the fair value measurement levels during the years ended December 31, 2024 or December 31, 2023.

All of the Company's debt securities are considered "available-for-sale" and are carried at fair value. The debt security category above may include federal agency obligations, U.S. Treasury securities, commercial and residential federal agency MBS, municipal securities, corporate bonds, and CDs, as held at those dates. The Company utilizes third-party pricing vendors to provide valuations on its debt securities. Fair values provided by the vendors were generally determined based upon pricing matrices utilizing observable market data inputs for similar or benchmark securities in active markets and/or based on a matrix pricing methodology which employs The Bond Market Association's standard calculations for cash flow and price/yield analysis, live benchmark bond pricing and terms/condition data available from major pricing sources. Therefore, management regards the inputs and methods used by third-party pricing vendors to be "Level 2 inputs and methods" as defined in the "fair value hierarchy." The Company periodically obtains a second price from an impartial third-party on debt securities to assess the reasonableness of prices provided by the primary independent pricing vendor.

The Company's equity securities portfolio fair value is measured based on quoted market prices for the shares; therefore, these securities are categorized as Level 1 within the fair value hierarchy.
The Bank is required to purchase FHLB stock at par value in association with advances from the FHLB. The stock is issued, redeemed, repurchased, and transferred by the FHLB only at their fixed par value. This stock is classified as a restricted investment and carried at FHLB par value which management believes approximates fair value; therefore, these securities are categorized as Level 2 measures.

The fair values of derivative assets and liabilities, which are comprised of back-to-back swaps and risk participation agreements, represent a Level 2 measurement and are based on settlement values adjusted for credit risks and observable market interest-rate curves. The settlement values are determined using widely accepted valuation techniques including discounted cash flow analysis on the expected cash flows of each derivative, reflecting the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest-rate curves. Credit risk adjustments consider factors such as the likelihood of default by the Company and its counterparties, its net exposures and remaining contractual life. The change in value of derivative assets and liabilities attributable to credit risk was not significant during the reported periods.

The fair value of individually evaluated collateral dependent loan balances in the table above represent those collateral dependent commercial loans where management has estimated the probable credit loss by comparing the loan's carrying value 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 are categorized as Level 3 within the fair value hierarchy. A specific allowance is assigned to the collateral dependent loan for the amount of management's estimated probable credit loss. The specific allowances assigned to the collateral dependent individually evaluated loans amounted to $6.2 million at December 31, 2024, compared to $2.8 million at December 31, 2023.
Letters of credit are conditional commitments issued by the Company to guarantee the financial obligation or performance of a customer to a third-party. The fair value of these commitments was estimated to be the fees charged to enter into similar agreements, and accordingly these fair value measures are deemed to be FASB Level 2 measurements. In accordance with the FASB, the estimated fair values of these commitments are carried on the Consolidated Balance Sheet as a liability and amortized to income over the life of the letters of credit, which are typically one year. The estimated fair value of these commitments carried on the Consolidated Balance Sheets at December 31, 2024 and December 31, 2023 were deemed immaterial.

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. The Company generally does not pool mortgage loans for sale, but instead sells the loans on an individual basis. To reduce the net interest rate exposure arising from its loan sale activity, the Company enters into the commitment to sell these loans at essentially the same time that the interest-rate lock commitment is quoted on the origination of the loan. The Company estimates the fair value of these derivatives based on current secondary mortgage market prices. These commitments are accounted for in accordance with FASB guidance. The fair values of the Company's derivative instruments are deemed to be FASB Level 2 measurements. At December 31, 2024 and December 31, 2023, the estimated fair value of the Company's interest-rate lock commitments and commitments to sell these mortgage loans were deemed immaterial.

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 December 31, 2024 and December 31, 2023:

Estimated Fair Values of Assets and Liabilities

In addition to disclosures regarding the measurement of assets and liabilities carried at fair value on the Consolidated Balance Sheet, 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 Consolidated Balance Sheet.

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 of their 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.

Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block]
Overall Process
We have developed and implemented a comprehensive multi-layered cybersecurity risk management program, consisting of a dedicated cybersecurity function, risk assessments, policies and procedures managed by internal and external resources, that we believe is reasonably designed to prevent, detect and respond to cyber risks and incidents. We utilize a set of tools and services, including regular network, endpoint and cloud monitoring, vulnerability assessments, penetration testing, a Security Information and Event Management system, and tabletop exercises to identify and assess material risks from cybersecurity threats and to evaluate our cyber defense capabilities.

Internal security controls are designed to align with standards set by the National Institute of Standard and Technology. We monitor emerging data protection laws, conduct background checks of our employees in specific technology and cybersecurity roles, apply least privilege access to users, test the maturity and readiness of our cybersecurity program, conduct table top exercises based on current threat scenarios to increase awareness, conduct phishing testing, provide cybersecurity training to our Board and employees, and provide cybersecurity alerts to our customers on ongoing threats. We monitor notifications and alerts from the Financial Services Information and Analysis Center and other industry cybersecurity sites to stay abreast of the most recent cybersecurity alerts.
Enterprise Risk Management Process Integration
The Company has implemented layered security approaches for all electronic delivery channels to detect, prevent and respond to rising cybersecurity risks. Management utilizes a combination of third-party information security assessments, key technologies, and ongoing internal and external evaluations to provide a level of protection of non-public personal information, to continually monitor and attempt to safeguard information on its operating systems, in cloud-based solutions, and those of third-party service providers, and to prevent, quickly detect and respond to attacks. The Company also utilizes firewall technology, multi-factor authentication, complex password construction, and a combination of software and third-party monitoring to detect and prevent intrusion, and cybersecurity threats, guard against unauthorized access, and continuously identify and prevent computer viruses on the Company's information solutions. To minimize debit card losses, the Company works with a third-party provider to establish parameters for allowable transaction activity, monitor transactions, and alert customers of potentially fraudulent activity.

The Bank maintains a written Information Security Program based on a collection of information security policies, regulatory requirements, standards, guidelines, processes, procedures, third-party recommendations, and industry best practices. The purpose of this Program is to establish a company-wide approach for assessing and protecting the integrity, availability, and confidentiality of the Bank’s information assets.

Third-party Access
The Company has a fully integrated third-party risk management program to identify, assess, monitor and mitigate risks associated with third-party relationships, including cybersecurity risks. Under the program, risk ratings are assigned to each of the vendors based on an assessment of the vendor, for a variety of factors, including its access to networks, systems, and confidential information. An assessment is conducted on each vendor to identify and measure the risks from cybersecurity threats that could impact our customer’s data and our environment. Third parties that have access to our systems or customer data must have appropriate technical and organizational security measures and security control principles based on commercially acceptable security standards, and we require third parties in this class to agree by contract to manage their cybersecurity risks.

In our Risk Factors, we describe whether and how risks from identified cybersecurity threats, including as a result of any previous cybersecurity incidents, have materially affected or are reasonably likely to materially affect us, including our business strategy, results of operations or financial condition.

Material Incidents
We are not aware of any risks from cybersecurity threats, including as a result of any previous cybersecurity incidents, that have materially affected or are reasonably likely to materially affect the Company, including our business strategy, results of operations or financial condition. Although we have a robust cybersecurity program that is designed to assess, identify, and manage material risks from cybersecurity threats, we cannot provide absolute surety that we have properly identified or mitigated all vulnerabilities or risks of incidents. We, and the third parties that we engage, are subject to constant and evolving threats of attack and cybersecurity incidents may be difficult to detect for periods of time. A cybersecurity incident could harm our business strategy, results of operations, financial condition, reputation, and/or subject us to regulatory actions or litigation which may result in fines, judgments or indictments.

Incidents and Risks
The Company has developed an Incident Response Plan to guide its actions in responding to real and suspected information security incidents. This includes unlawful, unauthorized, or unacceptable actions that involve a computer system or a computer network such as Distributed Denial of Service attacks, Corporate Account Takeover schemes, or ransomware. Additionally, an event that disrupts one of the Bank's service channels, whether from a security incident or not, is also considered an incident requiring a response under this program. These disclosure controls and procedures compel the Company to make accurate and timely disclosures of material events and incidents to both customers and regulatory authorities. The reaction to an incident aims to reduce potential damage and loss and to protect and restore confidence through timely communication and the restoration of normal operating conditions for computers, services, and information. Management will work closely with its cybersecurity insurance provider, cybersecurity legal counsel, and forensic experts when investigating and responding to cyber or ransomware attacks.

Summary of Significant Accounting Policies (Policies)
12 Months Ended
Dec. 31, 2024
Accounting Policies [Abstract]  
Organization of the Company and Basis of Presentation - Principles of Consolidation Organization of the Company and Basis of Presentation
 
The accompanying consolidated financial statements of Enterprise Bancorp, Inc. (the "Company," "Enterprise," "we," or "our"), a Massachusetts corporation, 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 the Company's operations are conducted through the Bank and its subsidiaries.
 
The Bank's subsidiaries include Enterprise Wealth Services, LLC, organized under the laws of the State of Delaware, to offer non-deposit investment products and services. 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 for the purpose of investing in a local NMTC project which provides federal tax incentives for investments in distressed communities. The NMTC are discussed in Note 15, " Income Taxes."

The Company's headquarters and the Bank's main office are located at 222 Merrimack Street in Lowell, Massachusetts. At December 31, 2024, the Company had 27 full-service branch banking offices serving the Northern Middlesex, Northern Essex and Northern Worcester counties of Massachusetts and Southern Hillsborough and Southern Rockingham counties in New Hampshire.

The FDIC and the Massachusetts Division of Banks (the "Division") have regulatory authority over the Bank. The Bank is also subject to certain regulatory requirements of the Board of Governors of the Federal Reserve System (the "Federal Reserve Board") and, with respect to its New Hampshire branch operations, the New Hampshire Banking Department. The business and operations of the Company are subject to the regulatory oversight of the Federal Reserve Board. The Division also retains supervisory jurisdiction over the Company.
Organization of the Company and Basis of Presentation - Basis of Accounting The accompanying audited consolidated financial statements and notes thereto have been prepared in accordance with U.S. GAAP and the instructions for SEC Form 10-K through the rules and interpretive releases of the SEC under federal securities law. In the opinion of management, the accompanying audited consolidated financial statements reflect all necessary adjustments consisting of normal recurring accruals for a fair presentation. All significant intercompany balances and transactions have been eliminated in the accompanying consolidated financial statements.
Organization of the Company and Basis of Presentation - Reclassifications Certain previous years' amounts in the consolidated financial statements, and notes thereto, have been reclassified to conform to the current year's presentation.
Organization of the Company and Basis of Presentation - Subsequent Events The Company has evaluated subsequent events and transactions from December 31, 2024, through the filing date of this Annual Report on Form 10-K with the SEC for potential recognition or disclosure as required by GAAP and determined that there were no material subsequent events requiring recognition or disclosure.
Segment Reporting Segment Reporting 
The Company operates as one strategic unit and therefore has only one reportable operating segment. Substantially all of the Company’s operations are conducted through its wholly owned banking subsidiary, which offers a full range of commercial, residential and consumer loan products, deposit products and cash management services, as well as wealth management and wealth services. The Company's business is not dependent on one, or a few customers, nor upon a particular industry, the loss of which would have a material adverse impact on the financial condition or operations of the Company. The identification of the single reportable business segment was determined based on the nature of the financial services provided, similar customer base and management’s evaluation of the consolidated financial information.

The Company's financial performance is monitored by the Chief Executive Officer and Chief Financial Officer, which together have been designated as the Chief Operating Decision Maker.
The CODM analyzes key metrics including consolidated net income and its major components to strategize and allocate resources. Revenue and expenses reviewed by the CODM are consistent with the consolidated statements of income, and the measure of segment assets reviewed by the CODM is consistent with the consolidated balance sheets.

The Company has reviewed the requirements of ASU 2023-07 and has determined that no additional segment disclosures are required, specifically as a result of the following:
the Company does not use disaggregated segment level for decision-making or resource allocation purposes,
no significant segment-specific expenses or performance metrics are used internally for decision-making or resource allocation purposes, and
the level of financial consolidation presented in our consolidated financial statements aligns with the CODM’s internal reporting and decision-making process
Merger Merger
On December 8, 2024, the Company entered into an Agreement and Plan of Merger (the "Merger Agreement") with Independent Bank Corp., a Massachusetts corporation ("Independent"), and Rockland Trust Company, a Massachusetts-chartered trust company and wholly owned subsidiary of Independent ("Rockland Trust"). Pursuant to the Merger Agreement, the Company will merge with and into Independent, with Independent being the surviving corporation (the "Merger"). Upon completion of the Merger, each outstanding share of Company common stock will convert into the right to receive 0.60 shares of Independent common stock and $2.00 in cash (the "Merger Consideration"). Each outstanding option to acquire a share of Company common stock, whether or not vested, will be converted into the right to receive cash in an amount equal to the amount by which the per share cash equivalent of the Merger Consideration (calculated in accordance with the Merger Agreement) exceeds the exercise price of the option. In addition, each award of Company restricted stock, whether or not vested, that is outstanding immediately prior to the effective time of the Merger will fully vest and be canceled and converted into the right to receive the Merger Consideration. Following the Merger, Enterprise Bank will merge with Rockland Trust, with Rockland Trust being the surviving institution. Completion of the Merger is subject to customary closing conditions, including receipt of regulatory approvals and approval of the Company’s shareholders. The Merger is expected to close in the second half of 2025. The Company has scheduled a Special Shareholder Meeting for April 3, 2025 to vote on the Merger and other related proposals. No vote of Independent shareholders is required.
Uses of Estimates Uses of Estimates
In preparing the consolidated 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 years 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. The most significant areas in which management applies critical assumptions and estimates are the estimates of the allowance for credit losses for loans and available for sale securities, the reserve for unfunded commitments, and the impairment review of goodwill, which are each discussed below.
Cash and Cash Equivalents Cash and Cash Equivalents
Cash equivalents are defined as highly liquid investments with original maturities of three months or less, that are readily convertible to known amounts of cash and present insignificant risk of changes in value due to changes in interest rates. The Company's cash and cash equivalents may be comprised of cash on hand and cash items due from banks, interest-earning deposits with banks (deposit accounts, excess reserve cash balances, money markets, and money market mutual fund accounts) and overnight and term federal funds sold to money center banks. Balances in cash and cash equivalents will fluctuate due primarily to the timing of net cash flows from deposits, borrowings, loans and investments, and the immediate liquidity needs of the Company.
Restricted Cash and Investments Restricted Cash and Investments
Certain of the Company's derivative agreements contain provisions for collateral to be posted if the derivative exposure exceeds a threshold amount. When the Company has pledged cash as collateral in relation to certain derivatives, the cash is carried as
restricted cash within "Interest-earning deposits with banks." See Note 9, "Derivatives and Hedging Activities," to the Company's consolidated financial statements of this Form 10-K below for more information about the Company's collateral related to its derivatives.

As a member of the FHLB, the Company is required to purchase certain levels of FHLB capital stock at par value in association with outstanding advances from the FHLB. From time-to-time, the FHLB may initiate the repurchase, at par value, of "excess" levels of its capital stock held by member banks. This stock is classified as a restricted investment and is carried at cost, which management believes approximates fair value. FHLB stock represents the only restricted investment held by the Company.
Management regularly reviews its holdings of FHLB stock for impairment, and as of December 31, 2024, the Company has determined that no allowance for credit losses on FHLB stock was necessary.
Investment Securities Investment Securities
 
Investments in debt securities that are intended to be held for indefinite periods of time, but which may not be held to maturity or on a long-term basis are considered to be "available-for-sale" and are carried at fair value.

Included as available-for-sale are debt securities that are purchased in connection with the Company's asset-liability risk management strategy and that may be sold in response to changes in interest rates, prepayment risk and other related factors. In instances where the Company has the positive intent to hold debt securities to maturity, these securities will be classified as held-to-maturity and carried at amortized cost. As of the balance sheet dates, all the Company's debt securities were classified as available-for-sale and carried at fair value.

Net unrealized appreciation and depreciation on debt securities available-for-sale, net of applicable income taxes, are recorded in the Company's Consolidated Statement of Comprehensive Income as a component of "Accumulated other comprehensive (loss) income." The net unrealized gain or loss in the Company's debt security portfolio fluctuates as market interest rates rise and fall. Due to the fixed rate nature of this portfolio, as market rates fall, the value of the portfolio rises, and as market rates rise, the value of the portfolio declines. The unrealized gains or losses on debt securities will also decline as the securities approach maturity.

The Company's equity securities are carried at fair value with changes in fair value recognized in the Company's Consolidated Income Statement as a component of "Other income." The net gains and losses on equity securities that will be recognized as a component of "Non-interest income" in the future will depend on the amount of dollars invested in equities, the magnitude of changes in equity markets and the amount of gains or losses realized through equity sales.
 
Investment securities' discounts are accreted and premiums are amortized over the period of estimated principal repayment using methods that approximate the interest method. Gains or losses on the sale of investment securities are recognized on the trade date on a specific identification basis.

ACL for Available-for-Sale Securities Methodology

In accordance with ASC "Financial Instruments—Credit Losses (Topic 326), the Company's expected credit losses on available-for-sale debt securities are presented as an allowance rather than as a write-down. The Company measures expected credit losses on available-for-sale securities based upon the unrealized gain or loss position of the security. For available-for-sale debt securities in an unrealized loss position, the Company evaluates qualitative criteria to determine any expected loss unless the Company intends to sell, or it is more likely than not that the Company will be required to sell before recovery of the amortized cost. In the latter two circumstances, the Company recognizes the entire difference between the security’s amortized cost basis and its fair value as a write-down of the investment balance with a charge to earnings. Otherwise, management’s analysis considers various factors, which include among other considerations (1) the present value of the cash flows expected to be collected compared to the amortized cost of the security, (2) duration and magnitude of the decline in value, (3) the financial condition of the issuer or issuers, and (4) structure of the security. If the Company does not expect to recover the entire amortized cost basis of the security, an allowance for credit losses for available-for-sale securities would be recorded, with a related charge to earnings, limited by the difference of the amortized cost of the security to its fair value. Subsequent measurements of the ACL for available-for-sale securities may result in a reversal of the allowance for credit losses, not to exceed the amount initially recognized. In addition, the Company has elected to exclude accrued interest from the measurement of the allowance for credit losses for available-for-sale debt securities and to continue to write-off uncollectible accrued interest receivable by reversing interest income.
At December 31, 2024, management performed its quarterly analysis of all securities with unrealized losses and determined that all were attributable to increases in market interest rates. Management concluded that no ACL for available-for-sale securities was considered necessary as of December 31, 2024 and anticipates they will mature or be called at par value. The Company does not intend to sell these investments and has determined, based upon available evidence, that it is more likely than not that the Company will not be required to sell each security before the recovery of its amortized cost basis.
Loans Held for Sale Loans Held for Sale
Depending on the current interest-rate environment, management projections of future interest rates and the overall asset-liability management program of the Company, management may elect to sell those fixed and adjustable-rate residential mortgage loans which are eligible for sale in the secondary market or hold some or all of this residential loan production for the Company's portfolio. Mortgage loans are generally not pooled for sale, but instead are sold on an individual basis. Enterprise may retain or sell the servicing when selling the loans. Loans sold are subject to standard secondary market underwriting and eligibility representations and warranties over the life of the loan and are subject to an early payment default period covering the first four payments for certain loan sales. Loans held for sale are carried at the lower of aggregate amortized cost or fair value on a separate line on the balance sheet. Fair value is based on comparable market prices for loans with similar rates and terms. When loans are sold, a gain or loss is recognized to the extent that the sales proceeds plus unamortized fees and costs exceed, or are less than, the carrying value of the loans. Gains and losses are determined using the specific identification method.
Loans Loans
 
Loans made by the Company to businesses, non-profits and professional practices include commercial real estate mortgage loans, construction and land development loans, secured and unsecured commercial loans and lines of credit, and letters of credit. Loans made to individuals include conventional residential mortgage loans, home equity lines, residential construction loans on owner-occupied primary and secondary residences, and secured and unsecured personal loans and lines of credit. Most loans granted by the Company are collateralized by real estate, equipment, or receivables and/or are guaranteed by the principals of the borrower.
 
Loans are reported at the principal amount outstanding, net of deferred origination fees and costs. The aggregate amounts of overdrawn deposit accounts are reclassified as loan balances. Loan origination fees received, offset by direct loan origination costs, are deferred and amortized using the straight-line method over three years to five years for lines of credit and demand notes or over the life of the related loans using the level-yield method for all other types of loans. When loans are paid off, the unamortized fees and costs are recognized as an adjustment to interest income.

Certain of the Company's directors, officers, principal shareholders, and their associates are credit customers of the Company in the ordinary course of business. In addition, certain directors are also directors, trustees, officers or shareholders of corporations and non-profit entities or members of partnerships that are customers of the Bank and that enter into loan and other transactions with the Bank in the ordinary course of business. All loans and commitments included in such transactions are on such terms, including interest rates, repayment terms and collateral, as those prevailing at the time for comparable transactions with persons who are not affiliated with the Bank and do not involve more than a normal risk of collectability or present other features unfavorable to the Bank.

From time to time, the Company participates with other banks in the financing of certain commercial projects. In order to qualify for sale accounting under GAAP, the rights and obligations of each participating bank are divided proportionately among the participating banks in an amount equal to their share of ownership and with equal priority among all banks. Each participation is governed by individual participation agreements executed by the lead bank and the participants at loan origination. When a participation qualifies as a sale under GAAP, the balances participated out to other institutions are not carried as assets on the Company's consolidated financial statements. When a participation does not qualify as a sale under GAAP, the loan is carried at gross principal outstanding and the balances participated out to other institutions are carried as secured borrowings on the Company's consolidated financial statements. The Company performs an independent credit analysis of each commitment and a review of the participating institution prior to participation in the loan, and an annual review thereafter of each participating institution. Loans originated by other banks in which the Company is the participating institution are carried in the loan portfolio at the Company's pro rata share of ownership. Participating loans with other institutions provide banks the opportunity to retain customer relationships and reduce credit risk exposure among each participating bank, while providing customers with larger credit vehicles than the individual bank might be willing or able to offer independently.
The Company seeks to lessen its credit risk exposure by managing its loan portfolio to avoid concentration by industry, relationship size and source of repayment, and through sound underwriting practices and the credit risk management function; however, management recognizes that credit losses will occur and that the amount of these losses will fluctuate depending on the risk characteristics of the loan portfolio and economic conditions.
Credit Risk Management and ACL for Loans Methodology Credit Risk Management and ACL for Loans Methodology
Inherent in the lending process is the risk of loss due to customer non-payment, or "credit risk." The Company's commercial lending focus may entail significant additional credit risks compared to long-term financing on existing, owner-occupied residential real estate. The credit risk management function focuses on a wide variety of factors and early detection of credit issues is critical to minimize credit losses. Accordingly, management regularly monitors these factors, among others, through ongoing credit reviews by the Company's Credit Department, an external loan review service, reviews by members of senior management as well as reviews by the Board's Loan Committee and the Board. These reviews include the assessment of internal credit quality indicators such as, among others, the risk classification of loans, past due and non-accrual loans, loans individually evaluated or with hardship modifications, and the level of foreclosure activity.

Credit Risk Management

The Company's loan risk rating system classifies loans depending on risk of loss characteristics. The classifications range from "substantially risk free" for the highest quality loans and loans that are secured by cash collateral, through a satisfactory range of "minimal," "moderate," "better than average," and "average" risk, all of which are considered "pass" rated credits. The adverse classifications range from "special mention," for loans that may need additional monitoring, to the more severe classifications of "substandard," "doubtful," and "loss" based on criteria established under banking regulations. Loans classified as "substandard" include those characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected. Loans classified as "doubtful" have all the weaknesses inherent in a substandard rated loan with the added characteristic that the weaknesses make collection or full payment from liquidation, based on existing facts, conditions, and values, highly questionable and improbable. Loans classified as "loss" are generally considered uncollectible at present, although long term recovery of part or all of loan proceeds may be possible. These "loss" loans would require a specific loss reserve or charge-off. Loans which are evaluated to be of weaker credit quality are classified as adverse and placed on the "watch asset list" and reviewed on a more frequent basis by management. Adversely classified loans may be accruing or in non-accrual status and may be additionally designated as individually evaluated or restructured, or some combination thereof.

Loans on which the accrual of interest has been discontinued are designated as non-accrual loans and the classified portions are credit downgraded to one of the adversely classified categories noted above. Accrual of interest on loans is generally discontinued when a loan becomes contractually past due, with respect to interest or principal, by 90 days, or when reasonable doubt exists as to the full and timely collection of interest or principal. When a loan is placed on non-accrual status, all interest previously accrued but not collected is reversed against current period interest income. Interest accruals are resumed on such loans only when payments are brought current and have remained current for a period of 180 days or when, in the judgment of management, the collectability of both principal and interest is reasonably assured. Interest payments received on loans in a non-accrual status are generally applied to principal on the books of the Company.

Loans individually evaluated consist primarily of loans for which management considers it probable that not all amounts due (principals and interest) will be collected in accordance with the original contractual terms and, to a lesser extent, if applicable, loans that management deems as individually significant or with unique risk characteristics or for some other reason based on management’s judgement. Management considers the individual payment status, net worth and earnings potential of the borrower, and the value and cash flow of the collateral as factors to determine if a loan will be paid in accordance with its contractual terms.

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.
Individually evaluated adversely classified loans will be considered for upgrade based on the borrower's sustained performance over time and their improving financial condition. Consistent with the criteria for returning non-accrual loans to accrual status, the borrower must demonstrate the ability to continue to service the loan in accordance with the original or modified terms and, in the judgment of management, the collectability of the remaining balances, both principal and interest, are reasonably assured.
A specific allowance is assigned to the loan for the amount of estimated credit loss. Individually evaluated loans are charged-off, in whole or in part, when management believes that the recorded investment in the loan is uncollectible.

ACL for Loans Methodology

In accordance with ASC "Financial Instruments—Credit Losses (Topic 326)," the CECL methodology requires early recognition of credit losses using a lifetime credit loss measurement approach that also requires the consideration of reasonable and supportable forecasts in the estimate. The CECL methodology is applicable to the loan portfolio, measured at amortized cost. It also applies to off-balance sheet credit exposures such as unadvanced loan & line balances, commitments to originate loans, standby letters of credit, and other similar instruments, which are not unconditionally cancellable. Additionally, the Company has elected to continue to present the accrued interest receivable balance on loans separate from amortized costs, exclude accrued interest from the measurement of the allowance for credit losses for loans and to continue to write-off uncollectible accrued interest receivable by reversing interest income.

The ACL for loans is established through a provision for credit losses, recorded as a direct charge to earnings. The ACL for loans is a valuation account that is deducted from the amortized cost to present the net amount of the loan portfolio expected to be collected. Credit losses are charged against the ACL for loans when management believes that the collectability of the amortized cost of a loan's principal balance is unlikely. Recoveries on loans previously charged-off are credited to the ACL for loans, generally at the time cash is received on a charged-off account.

Arriving at an appropriate level of ACL for loans involves a high degree of management judgement. The underlying assumptions, estimates and assessments used to estimate the ACL for loans reflects the Company’s best estimate of model assumptions and forecasted conditions at that time. Changes in such estimates can significantly affect the ACL for loans and the provision for credit losses. 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. It is possible and likely that the Company will experience credit losses that are different from the current estimates and future additions to the ACL for loans may be necessary. 

On a quarterly basis, the Company makes an assessment to estimate the ACL for loans necessary to cover expected lifetime credit losses. The adequacy of the ACL for loans is reviewed and evaluated on a regular basis by an internal management committee, a sub-committee of the Company's Board of Directors (the "Board") and the full Board.

In making its assessment on the adequacy of the ACL for loans, management considers several quantitative and qualitative factors from internal and external sources relating to past events, current conditions, and reasonable and supportable forecasts.
The Company uses a systematic methodology to measure the amount of estimated loan losses. The methodology uses a two-tiered approach that applies general reserves for larger groups of homogeneous loans, segmented by loan type and specific reserves for loans individually evaluated.

Loans collectively evaluated

Management segments loans of similar risk characteristics using the Open Pool method by first calculating each segment's loss rate as net charge-offs over the expected average life of each segment, divided by the average loan balance over that same period. The historic loss factor is an average of the loss rate over a 5-year look-back period, which approximates the average age of charged-off loans. These historic loss factors are then adjusted up or down based on management's assessment of quantitative and qualitative factors. These key factors including quantitative facts about the loan portfolio such as: commercial concentrations by industry, property type and real estate location; the growth and composition of the loan portfolio; trends in risk classification of individual loans and higher risk problem assets; the level of delinquent, non-performing, and individually evaluated loans; the level of hardship loan modifications; foreclosure activity; net charge-offs; as well as trends in the general levels of these indicators. In addition, management monitors qualitative factors such as: expansion in the Company's geographic market area; the experience level of lenders and any changes in underwriting criteria; Market conditions, including general conditions in the multi-family, commercial real estate and construction and development markets in the Company's local region as well as changes in current and forecasted economic conditions, such as changes in gross domestic product, the unemployment rate and new jobs created, real estate values, commercial vacancy rates, recession risk estimates and other
relevant economic factors. Management uses a two-year reasonable and supportable forecast, and for periods beyond the forecast period, reverts immediately to historical loss rates. Management weighs the current effect of each of these areas on each particular loan segment in determining the allowance allocation factors. Management must exercise significant judgment when evaluating the effect of these quantitative and qualitative factors on the amount of the ACL for loans as data may not be reasonably available or directly applicable to determine the precise impact of a factor on the collectability over the remaining average life. The methodology contemplates a range of acceptable levels for these factors due to the subjective nature of the factors and the qualitative considerations related to the credit risk in the portfolio.

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, 2023.

Management recognizes that additional issues may also impact the estimate of expected credit losses to some degree. From time to time management will re-evaluate the qualitative factors, regulatory guidance, and industry data in use in order to consider the impact of other issues which, based on changing circumstances, may become more significant in the future.

Loans individually evaluated

For loans that are individually evaluated, as discussed above, management estimates the credit loss by comparing the loan's carrying value against either (i) the present value of the expected future cash flows discounted at the loan's effective interest-rate; (ii) the loan's observable market price; or (iii) the expected realizable fair value of the collateral, in the case of collateral dependent loans. A specific allowance is assigned to the loan for the amount of estimated credit loss. Individually evaluated loans are charged-off, in whole or in part, when management believes that the recorded investment in the loan is uncollectible.

Reserve for unfunded commitments

The reserve for unfunded commitments is included in the line item "Accrued expenses and other liabilities" on the Company’s Consolidated Balance Sheets. Management applies the CECL methodology to off-balance sheet commitments in a manner consistent with on-balance sheet loan loss rates. Additionally, the estimate of credit loss incorporates assumptions for both the likelihood and amount of funding over the estimated life of the commitments. Management periodically reviews and updates its assumptions for estimated funding rates.
Other Real Estate Owned Other Real Estate Owned
 
Real estate acquired by the Company through foreclosure proceedings or the acceptance of a deed in lieu of foreclosure is classified as OREO. When property is acquired, it is recorded at the estimated fair value of the property acquired, less estimated costs to sell, establishing a new cost basis and carried on the Consolidated Balance Sheet in the line item "Prepaid expenses and other assets." The estimated fair value is based on market appraisals and the Company's internal analysis. Any loan balance more than the estimated realizable fair value on the date of transfer is charged to the allowance for credit losses on that date. All costs incurred thereafter in maintaining the property, as well as subsequent declines in fair value are charged to non-interest expense.
Premises and Equipment Premises and Equipment
Land is carried at cost. All other premises and equipment costs are stated at cost less accumulated depreciation and amortization. Depreciation or amortization is computed on a straight-line basis over the lesser of the estimated useful lives of the asset or the respective lease term (including renewal options reasonably certain to be exercised) for leasehold improvements generally as follows:

Bank premises, land improvements and leasehold improvements
10 to 39 years
Computer software and equipment
3 to 5 years
Furniture, fixtures and equipment
3 to 10 years
Leases Leases
The Company leases office space, space for ATM locations and certain branch locations under noncancellable operating leases,
several of which have renewal options to extend lease terms. Upon commencement of a new lease, the Company will recognize a ROU asset and corresponding lease liability on the Consolidated Balance Sheet for all leases with terms longer than 12 months. The lease liability represents the present value of the future lease payments while the ROU asset represents the lease liability plus any lease prepayments and initial direct costs.

The Company’s operating lease agreements contain both lease and non-lease components (such as common area maintenance), which are generally accounted for separately. To calculate the lease liability, the Company uses its incremental borrowing rate as the discount rate to determine the net present value of the lease liability. In determining the term of a lease, the Company included option renewal periods that it considered reasonably certain to be exercised.

The Company recognizes lease expense on a straight-line basis in the "Occupancy and equipment expenses" line item within the non-interest expense section of the Consolidated Statement of Income.
Bank Owned Life Insurance Bank Owned Life Insurance
 
The Company owns BOLI on certain current and former senior and executive officers, utilizing the tax-exempt earnings on BOLI to offset the cost of the Company's benefit plans. The cash surrender value of these policies is included as an asset on the Consolidated Balance Sheet, and any increases in cash surrender value are recorded as income on bank owned life insurance on the Consolidated Statement of Income.
Impairment of Long-Lived Assets Other than Goodwill Impairment of Long-Lived Assets Other than Goodwill
 
The Company reviews long-lived assets, including premises, equipment, and lease right of use assets for impairment on an ongoing basis or whenever events or changes in business circumstances indicate that the remaining useful life may warrant revision or that the carrying amount of the long-lived asset may not be fully recoverable. If impairment is determined to exist, any related impairment loss is recognized through a charge to earnings. Impairment losses on assets disposed of, if any, are based on the estimated proceeds to be received, less cost of disposal.
Goodwill Goodwill
 
Goodwill is carried on the Company's consolidated financial statements and is related to the Company's acquisition of two branch offices in July 2000.

In accordance with GAAP, the Company does not amortize goodwill and instead, at least annually, evaluates whether the carrying value of goodwill has become impaired. A determination that goodwill has become impaired results in an immediate write-down of goodwill to its determined value with a resulting charge to the Company's Consolidated Statement of Income. Goodwill is evaluated at the reporting unit level. In the case of the Company, the services offered through the Bank and subsidiaries are managed as one strategic unit and represent the Company’s only reportable operating segment.
The Company has the option to perform either (i) a qualitative assessment of whether it is "more likely than not" that the reporting unit's fair value is less than its book value, or (ii) a quantitative assessment.

1.Management's qualitative assessment would take into consideration, among other items, macroeconomic conditions, industry and market considerations, cost or margin factors, financial performance and share price. Based on the qualitative assessment, if the Company were to conclude: a) it is "more likely than not" that the fair value of a reporting unit exceeds its book value, goodwill is deemed not impaired, or b) it is "more likely than not" that the fair value of a reporting unit is less than its book value, a quantitative goodwill analysis must be performed.
2.The Company may elect to forgo the qualitative assessment and perform the quantitative analysis even if management believes that is "more likely than not" that goodwill is not impaired. The quantitative goodwill analysis compares the fair value of the reporting unit with its book value, including goodwill. If the fair value of the reporting unit equals or exceeds its book value, goodwill is deemed not impaired. If the book value of the reporting unit exceeds its fair value, a goodwill impairment loss is recognized for the difference between these amounts, not exceeding the goodwill carrying amount.
Wealth Assets Under Management and Administration Wealth Assets Under Management and Administration
 
Wealth assets under management consist of assets managed through Enterprise Wealth Management and Enterprise Wealth Services. Wealth assets under administration consist of 401(k) plans, trust, and custodial accounts. Wealth assets under management and administration are not included in the Consolidated Balance Sheets because they are not assets of the Company.
Derivatives and Hedging Derivatives and Hedging
 
The Company records all derivatives on the balance sheet at fair value. Asset derivatives are included in the line item "Prepaid expenses and other assets," and liability derivatives are included in the "Accrued expenses and other liabilities" line item on the Consolidated Balance Sheets.

The accounting for changes in the fair value of derivatives depends on the intended use of the derivative. On the date the derivative instrument is entered into, the Company designates whether the derivative is part of a hedging relationship (i.e., cash flow or fair value hedge). The Company also assesses, both at the hedge’s inception and on an ongoing basis, whether the derivatives used in hedging transactions are highly effective in offsetting the changes in cash flows or fair values of hedged items.

Fair value hedges are considered a hedge of the exposure to changes in the fair value of an asset, liability or firm commitment attributable to a particular risk, such as interest rate risk. For derivatives designated and qualifying as fair value hedges, changes in the fair value are recognized in earnings.

Cash flow hedges are considered a hedge of the exposure to the variability in expected future cash flows, or other types of forecasted transactions. For derivatives designated and qualifying as cash flow hedges, changes in the fair value of derivative instruments that are highly effective are recorded in other comprehensive income (loss), net of tax and subsequently reclassified into earnings in the same period during which the hedged transaction affects earnings. Any hedge ineffectiveness is recognized directly in earnings.

For derivative instruments not designated as hedging instruments, such as back-to-back interest rate swaps and risk participation agreements, changes in fair value are recognized in earnings.

See Note 9, "Derivatives and Hedging Activities," to the Company's consolidated financial statements of this Form 10-K, contained below, for further information on the Company's derivative and hedging activities.
Revenue Recognition Revenue Recognition
Interest and dividend income (primarily loan interest income from customers) are our primary sources of revenue and are outside of the scope of ASC 606, "Revenue from Contracts with Customers," and are accounted for under other ASC topics. The core principles of this standard require an entity to recognize revenue on the transfer of goods and services to customers as performance obligations are satisfied.

The primary areas of income for the Company within the scope of ASC 606 are wealth management fees and deposit and interchange fees which are components of non-interest income on the Company's Consolidated Statements of Income and are discussed below.

Wealth management fees consist of income generated through our wealth management services. Wealth management income is generated primarily by managing customers' financial assets. Revenue is recognized as our performance obligation is completed each month. Revenue earned through our wealth services platform is generated through a third-party arrangement to refer, manage and service customers. For new sales and referrals along with transactional type charges, the performance obligation is based on a point in time and the payment is received and revenue is recognized in the same month as the revenue generating activity. For managing and servicing customers, revenue is recognized when our performance obligation is completed each month.

Deposit and interchange fees are comprised of deposit account related charges and income generated from electronic payment interchanges. Deposit account charges consist of certain transactional analysis fees net of earning balance credits, monthly account service fees, and transactional fees such as overdraft fees. Analysis and monthly account services fees are recognized
over the period the service is performed. For transactional fees, the performance obligation and the revenue are recognized at a point of time and payment is typically received as the service is rendered. Interchange income is generated primarily from retail debit card transactions processed through the card payment network. The performance obligation and the revenue are recognized when the service is performed.
The following non-interest income components are not subject to ASC 606: income on BOLI, net gains/losses on investment securities, and net gains on sales of loans, and are covered under other ASC topics. The remaining revenue items in non-interest income are not material.
Stock Based Compensation Stock-Based Compensation
 
The Company currently has one active stock incentive plan: The Enterprise Bancorp, Inc. 2016 Stock Incentive Plan, as amended (the "2016 Plan"). The 2016 Plan permits the Board to grant, under various terms, both incentive and non-qualified stock options (for the purchase of newly issued shares of common stock), restricted stock, restricted stock units and stock appreciation rights to officers and other employees, and to non-employee directors and consultants. The 2016 Plan also allows for newly issued shares of common stock to be issued without restrictions to officers and other employees, and non-employee directors and consultants.

As of December 31, 2024, 270,474 common shares remained available for future grants under the 2016 Plan. Awards previously granted under an earlier, now expired plan remain outstanding and may be exercised through 2028.

Under terms of the 2016 Plan, options exercised and restricted stock awards vested may be net settled to cover payment for option costs and employee tax obligations, resulting in shares of common stock being reacquired by the Company and returned to the pool of shares reserved for issuance under the incentive plans. In accordance with Massachusetts law, shares reacquired by the Company will be treated as authorized but unissued shares.

The non-employee members of the Company's Board may opt to receive newly issued shares of the Company's common stock in lieu of cash compensation for attendance at Board and Board Committee meetings. These shares are issued annually each January for Board meetings held in the previous year. Directors must make an irrevocable election to receive shares of common stock in lieu of cash fees prior to December 31st of the preceding year. Directors are granted shares of common stock in lieu of cash fees based on an average quarterly close price of the Company's common stock on the NASDAQ Global Market during the year.

From time to time, the Company issues shares to community members for consulting on regional advisory councils and grants shares of fully vested stock as employee anniversary awards. These shares vest immediately and the cost, which is based on the market price on the date of the grant and deemed to be immaterial, is expensed in the period in which the services are rendered.

The Company's consolidated financial statements include stock-based compensation expense for the portion of stock option awards and stock awards for which the requisite service has been rendered during the period or the estimate of achieving certain predefined performance objectives. The compensation expense has been recorded based on the estimated grant-date fair value of the stock option awards with no adjustment for estimated forfeitures, or in the case of stock awards, the market value of the common stock on the date of grant. Expense adjustments are made for actual forfeitures as they occur.

The Company will recognize the remaining estimated compensation expense for the portion of outstanding awards and compensation expense for any future awards, net of actual forfeitures, as the requisite service is rendered (i.e., on a straight-line basis over the remaining vesting period of each award) or as performance objectives are met. Stock awards that do not require future service ("vested awards") will be expensed immediately. Stock-based compensation also includes director stock compensation for stock awards and stock in lieu of cash fees, both included in other operating expenses.
Income Taxes Income Taxes
 
The Company and its subsidiaries file income tax returns in the U.S. federal jurisdiction and various states, within the directives of the respective enacted tax legislation. The Company uses the asset and liability method of accounting for income taxes.
Under this method, deferred tax assets and liabilities are recognized for the future tax expense or benefit attributable to differences between the financial statement carrying amounts and the tax basis of assets and liabilities. The deferred tax assets and liabilities are reflected at currently enacted income tax rates applicable to the period in which the deferred tax assets or liabilities are expected to be realized or settled. As changes in tax laws or rates are enacted, deferred tax assets and liabilities will be adjusted accordingly through the provision for income taxes in the period that includes the enactment date, which may be earlier than the effective date.

The Company's policy is to classify interest resulting from underpayment of income taxes as income tax expense in the first period the interest would begin accruing according to the provisions of the relevant tax law. The Company classifies penalties resulting from underpayment of income taxes as income tax expense in the period for which the Company claims or expects to claim an uncertain tax position or in the period in which the Company's judgment changes regarding an uncertain tax position.

The income tax provisions will differ from the expense that would result from applying the federal statutory rate to income before taxes, due primarily to the impact of state tax expense, tax-exempt interest from certain investment securities, loans and BOLI and the tax impact from equity compensation activity.

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.
As of December 31, 2024, the Company had one investment in a local NMTC project which provides federal tax incentives for investments in distressed communities. The investment is accounted for using the proportional amortization method and will be amortized over seven years, which represents the period that the tax credits and other tax benefits will be utilized.
Earnings Per Share Earnings per Share
 
Basic earnings per share are calculated by dividing net income available to common shareholders by the weighted average number of common shares outstanding (including participating securities) during the year. The Company's only participating securities are unvested restricted stock awards that contain non-forfeitable rights to dividends. Diluted earnings per share reflects the effect on weighted average shares outstanding of the number of additional shares outstanding if dilutive stock options were converted into common stock using the treasury stock method.
Reporting Comprehensive Income Reporting Comprehensive Income
Comprehensive income is defined as all changes to shareholders' equity except investments by and distributions to shareholders. Net income is one component of comprehensive income, with other components referred to in the aggregate as other comprehensive income. The Company's other comprehensive income components are the changes in fair value of debt securities and cash flow hedges, both net of income taxes. Pursuant to GAAP, the Company initially excludes the unrealized holding gains and losses from net income; however, they are later reported as reclassifications out of accumulated other comprehensive income into net income when circumstances warrant.

When debt securities are sold, the reclassification of realized gains and losses on available-for-sale securities are included on the Consolidated Statements of Income under the "Non-interest income" subheading on the line item "Net gains (losses) on sales of available-for-sale debt securities" and the related income tax expense is included in the line item "Provision for income taxes."
For cash flow hedges of interest rate risk, the change in fair value will be reclassified in the same period during which the hedged transaction affects earnings, to either interest expense as interest is incurred on the Company's hedge liability, or to interest income as interest is earned on the Company's hedge asset. The reclassification of gain or loss on the derivatives are included on the Consolidated Statements of Income under "Interest income" or "Interest expense" line item and the related income tax expense is included in the line item "Provision for income taxes,"
Dividends Dividends
Neither the Company nor the Bank may declare or pay dividends on its stock if the effect thereof would cause shareholders'
equity to be reduced below applicable regulatory capital requirements or if such declaration and payment would otherwise violate regulatory requirements.

As the principal asset of the Company, the Bank currently provides the only source of cash for the payment of dividends by the Company. Under Massachusetts law, trust companies such as the Bank may pay dividends only out of "net profits" and only to the extent that such payments will not impair the Bank's capital stock. Any dividend payment that would exceed the total of the Bank's net profits for the current year plus its retained net profits of the preceding two years would require the Massachusetts Division of Banks' approval. Applicable provisions of the FDIC Improvement Act also prohibit a bank from paying any dividends on its capital stock if the bank is in default on the payment of any assessment to the FDIC or if the payment of dividends would otherwise cause the bank to become "undercapitalized." Any restrictions, regulatory or otherwise, on the ability of the Bank to pay dividends to the Company may restrict the ability of the Company to pay dividends to the holders of its common stock.

The statutory term "net profits" essentially equates with the accounting term "net income" and is defined under the Massachusetts banking statutes to mean the remainder of all earnings from current operations plus actual recoveries on loans and investments and other assets after deducting from such total all current operating expenses, actual losses, accrued dividends on any preferred stock and all federal and state taxes.

In addition, the Company maintains a dividend reinvestment and direct stock purchase plan which enables shareholders, at their discretion, to elect to reinvest cash dividends paid on their shares of the Company's common stock by purchasing additional shares of common stock from the Company at a purchase price equal to fair market value. Under the DRSPP, shareholders and new investors also have the opportunity to purchase shares of the Company's common stock without brokerage fees, subject to monthly minimums and maximums. Effective December 9, 2024, all share purchases under the DRSPP were suspended as
a result of the pending merger with Independent.
