Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies (a) Organization of the Company and Basis of Presentation The accompanying unaudited consolidated interim financial statements and these notes should be read in conjunction with the December 31, 2023 audited consolidated financial statements and notes thereto contained in the Annual Report on Form 10-K of Enterprise Bancorp, Inc. (the "Company," "Enterprise," "we," or "our") for the year ended December 31, 2023 (the "2023 Annual Report on Form 10-K") as filed with the SEC on March 8, 2024. The Company has not materially changed its significant accounting policies from those disclosed in its 2024 Annual Report on Form 10-K. See Item (b), " Recent Accounting Pronouncements ," below in this Note 1. The accompanying unaudited consolidated interim financial statements of the Company include the accounts of the Company and its wholly owned subsidiary, Enterprise Bank and Trust Company, commonly referred to as Enterprise Bank (the "Bank"). The Bank is a Massachusetts trust company and state chartered commercial bank organized in 1989. Substantially all of the Company's operations are conducted through the Bank and its subsidiaries. The services offered through the Bank and its subsidiaries are managed as one strategic unit and represent the Company's only reportable operating segment. The accompanying unaudited consolidated interim financial statements, and notes thereto, in this Quarterly Report on Form 10-Q for the quarterly period ended September 30, 2024 (this "Form 10-Q"), have been prepared in accordance with U.S. GAAP for interim financial information and the SEC instructions for Quarterly Reports on Form 10-Q. In the opinion of management, the accompanying unaudited consolidated interim financial statements reflect all necessary adjustments, consisting of normal recurring accruals and elimination of intercompany balances, for a fair presentation. Interim results are not necessarily indicative of results to be expected for the entire year, or any future period. (b) Recent Accounting Pronouncements Accounting pronouncements not yet adopted by the Company In October 2023, the FASB issued ASU 2023-06, "Disclosure Improvements — Codification Amendments in Response to the SEC's Disclosure Update and Simplification Initiative." This ASU amends the ASC to incorporate certain disclosure requirements from SEC Release No. 33-10532, Disclosure Update and Simplification, that was issued in 2018. The effective date for each amendment will be the date on which the SEC's removal of that related disclosure from Regulation S-X or Regulation S-K becomes effective, with early adoption prohibited. ASU 2023-06 is not expected to have a material impact on our consolidated financial statements. In November 2023, the FASB issued ASU 2023-07, "Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures." The amendments in this ASU are intended to improve reportable segment disclosure requirements primarily through enhanced disclosures about significant segment expenses. For public business entities, the amendments are effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. ASU 2023-07 is not expected to have a material impact on our consolidated financial statements. In December 2023, the FASB issued ASU 2023-09, "Income Taxes (Topic 740): Improvements to Income Tax Disclosures." This ASU requires public business entities, on an annual basis, to disclose specific categories in the rate reconciliation and provide additional information for reconciling items that meet a quantitative threshold (if the effect of those reconciling items is equal to or greater than 5 percent of the amount computed by multiplying pretax income by the applicable statutory income tax rate). 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. (c) Subsequent Events

Management concluded that no ACL for available-for-sale securities was necessary as of September 30, 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 any such security before the recovery of its amortized cost basis.

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 $135.2 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 $611.9 million and $650.8 million at September 30, 2024 and December 31, 2023, respectively.

ACL for Loans	ACL for Loans There have been no material changes to the Company's ACL for loans methodology, underwriting practices, or credit risk management system used to estimate credit loss exposure as described in the 2023 Annual Report on Form 10-K. See Note 4, "Credit Risk Management and ACL for Loans," to the Company's audited consolidated financial statements contained in the 2023 Annual Report on Form 10-K and Part II, Item 7, "Management's Discussion and Analysis of Financial Condition and Results of Operations," under the subheading "Accounting Policies/Critical Accounting Estimates," of the Company's 2023 Annual Report on Form 10-K. The credit risk management function of the Company evaluates a wide variety of factors, as early detection of credit issues is critical to minimizing credit losses. Accordingly, management regularly monitors internal credit quality indicators such as, the risk classification of loans, past due and non-accrual loans, individually evaluated loans, loan modifications, and the level of foreclosure activity, among other items. These credit quality indicators are outlined below. Risk ratings and adversely classified loans The Company's loan risk rating system classifies loans depending on risk of loss characteristics. Adversely classified ratings for loans determined to be of weaker credit range from "special mention," for loans that may need additional monitoring, to the more severe adverse classifications of "substandard," "doubtful," and "loss" based on criteria established under banking regulations. The following tables present the amortized cost basis of the Company's loan portfolio risk ratings within portfolio classifications, by origination date, or revolving status as of the dates indicated:

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 increase in non-accrual loans from December 31, 2023 to September 30, 2024 was due primarily to two commercial construction loans that were deemed collateral dependent and added to non-accrual during the period. At September 30, 2024 and December 31, 2023, additional funding commitments for non-accrual loans were immaterial. Collateral dependent loans The total recorded investment in collateral dependent loans amounted to $27.6 million at September 30, 2024 compared to $13.7 million at December 31, 2023.

Loan modifications to borrowers experiencing financial difficulty The Company works 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.

(2) The assets and liabilities related to the pay fixed, receive floating interest-rate contracts are subject to a master netting agreement and are presented net in the Company's Consolidated Balance Sheet. The Company had no derivatives designated as cash flow hedges at either September 30, 2024 or December 31, 2023. Derivatives designated as hedging instruments Fair value hedges Derivatives designated as fair value hedges are utilized to mitigate the risk of adverse interest-rate fluctuations on specifically identified assets or liabilities. The Company's fair value hedges are used to manage its exposure to changes in the fair value of hedged items caused by changes in interest rates. The Company had three interest rate swap agreements with a combined notional value of $100.0 million at September 30, 2024 and December 31, 2023. 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. The table below presents the carrying amount of hedged items and cumulative fair value hedging basis adjustments for the periods presented: September 30, 2024 December 31, 2023 (Dollars in thousands) Balance Sheet Location of Hedged Item Carrying Amount of Hedged Assets Cumulative Amount of Fair Value Hedging Adjustment Included in the Carrying Amount of the Hedged Assets Carrying Amount of Hedged Assets Cumulative Amount of Fair Value Hedging Adjustment Included in the Carrying Amount of the Hedged Assets Interest-rate contracts - loans Loans $ 100,682 $ 682 $ 100,755 $ 755 The table below presents the gains (losses) from interest rate derivatives accounted for as fair value hedges and the related hedged items during the periods indicated: Three months ended Nine months ended (Dollars in thousands) Affected Income Statement Line Item September 30, September 30, September 30, September 30, Derivatives designated as fair value hedges: Fair value adjustments on derivatives Net interest income $ (847) $ 134 $ 58 $ 393 Fair value adjustments on hedged instrument Net interest income 854 (141) (73) (404) Total $ 7 $ (7) $ (15) $ (11) Derivatives not subject to hedge accounting Interest-rate Contracts Each back-to-back interest-rate swap consists of two interest-rate swaps (a customer swap and offsetting counterparty swap) and amounted to a total number of four interest-rate swaps outstanding at September 30, 2024 and 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 nine months ended September 30, 2024 or September 30, 2023. Interest-rate swaps with counterparties are subject to master netting agreements, while interest-rate swaps with customers are not. At September 30, 2024 and December 31, 2023, all back-to-back swaps with the counterparty were in asset positions, therefore there was no netting reflected in the Company's Consolidated Balance Sheets as of the respective dates. Risk Participation Agreements The Company enters into 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 September 30, 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 September 30, 2024 and December 31, 2023, the Company had credit risk exposure relating to interest-rate swaps with counterparties of $223 thousand and $492 thousand, respectively and cash posted by counterparties amounted to $120 thousand and $590 thousand at September 30, 2024 and December 31, 2023, respectively. As of September 30, 2024 and December 31, 2023, cash collateral posted by the Company amounted to $760 thousand and $570 thousand, respectively. As of September 30, 2024, the fair value of derivatives related to these agreements was at a net liability position of $457 thousand, which excludes any adjustment for nonperformance risk.

Earnings per Share	Earnings per Share The table below presents the increase in average shares outstanding, using the treasury stock method, for the diluted earnings per share calculation for the periods indicated: Three months ended September 30, Nine months ended September 30, 2024 2023 2024 2023 Basic weighted average common shares outstanding 12,428,543 12,247,892 12,370,812 12,210,740 Dilutive shares 9,617 16,886 8,578 23,121 Diluted weighted average common shares outstanding 12,438,160 12,264,778 12,379,390 12,233,861 Stock options outstanding that were determined to be anti-dilutive, and therefore excluded from the calculation of dilutive shares, amounted to 79,177 and 101,793 for the three and nine months ended September 30, 2024, respectively, compared to 105,166 and 48,525 for the three and nine months ended September 30, 2023, respectively. These stock options, which were not dilutive, may potentially dilute earnings per share in the future. Unvested participating restricted stock awards amounted to 179,451 shares and 130,039 shares as of September 30, 2024 and December 31, 2023, respectively.

Fair Value Measurements

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: September 30, 2024 Fair Value Measurements Using: (Dollars in thousands) Fair Value (Level 1) (Level 2) (Level 3) Assets measured on a recurring basis: Debt securities $ 622,527 $ — $ 622,527 $ — Equity securities 9,448 9,448 — — FHLB stock 2,482 — 2,482 — Interest-rate swaps 481 — 481 — Assets measured on a non-recurring basis: Individually evaluated loans (collateral dependent) 11,181 — — 11,181 Liabilities measured on a recurring basis: Interest-rate swaps $ 1,183 $ — $ 1,183 $ — RPAs sold 55 — 55 — December 31, 2023 Fair Value Measurements Using: (Dollars in thousands) Fair Value (Level 1) (Level 2) (Level 3) Assets measured on a recurring basis: Debt securities $ 661,113 $ — $ 661,113 $ — Equity securities 7,058 7,058 — — FHLB stock 2,402 — 2,402 — Interest-rate swaps 630 — 630 — Assets measured on a non-recurring basis: Individually evaluated loans (collateral dependent) 1,595 — — 1,595 Liabilities measured on a recurring basis: Interest-rate swaps $ 1,390 $ — $ 1,390 $ — RPAs sold 65 — 65 — The Company utilizes third-party pricing vendors to provide valuations on its debt securities. The Company's equity portfolio fair value is measured based on quoted market prices for the shares; therefore, these securities are categorized as Level 1 within the fair value hierarchy. The Bank is required to purchase FHLB stock at par value in association with advances from the FHLB. The stock is issued, redeemed, repurchased and transferred by the FHLB only at their fixed par value. This stock is classified as a restricted investment and carried at FHLB par value which management believes approximates fair value; therefore, these securities are categorized as Level 2 measures. The fair values of derivative assets and liabilities, which are comprised of back-to-back swaps, fair value hedges and risk participation agreements, represent a FASB Level 2 measurement and are based on settlement values adjusted for credit risks and observable market interest-rate curves. The Company utilizes third-party vendors to provide valuations on its derivative assets and liabilities. Refer also to Note 8, "Derivatives and Hedging Activities," this Form 10-Q, contained above, for additional information on the Company's interest-rate swaps. For loans individually assessed and deemed to be collateral dependent management has estimated the value and the probable credit loss by comparing the loan's amortized cost against the expected realizable fair value of the collateral (appraised value, or internal analysis, less estimated cost to sell, adjusted as necessary for changes in relevant valuation factors subsequent to the measurement date). Certain inputs used in these assessments, and possible subsequent adjustments, are not always observable, and therefore, collateral dependent loans carried at realizable fair value are categorized as Level 3 within the fair value hierarchy. A specific reserve is assigned to the collateral dependent loan for the amount of management's estimated probable credit loss. The specific reserve assigned to individually evaluated loans that are collateral dependent amounted to $8.0 million at September 30, 2024, compared to $2.8 million at December 31, 2023. The following table presents additional quantitative information about assets measured at fair value on a non-recurring basis for which the Company utilized Level 3 inputs (significant unobservable inputs for situations in which there is little, if any, market activity for the asset or liability) to determine fair value as of September 30, 2024 and December 31, 2023: Fair Value (Dollars in thousands) September 30, 2024 December 31, 2023 Valuation Technique Unobservable Input Unobservable Input Value or Range Assets measured on a non-recurring basis: Individually evaluated loans (collateral dependent) $ 11,181 $ 1,595 Appraisal of collateral Appraisal adjustments (1) 15% - 75% _______________________________ (1) Appraisals may be adjusted by management for qualitative factors such as economic conditions and estimated liquidation expenses. Estimated Fair Values of Assets and Liabilities In addition to disclosures regarding the measurement of assets and liabilities carried at fair value on the Company's Consolidated Balance Sheets, the Company is also required to disclose fair value information about financial instruments for which it is practicable to estimate that value, whether or not recognized on the Company's Consolidated Balance Sheets. Financial instruments for which the fair value is disclosed but not recognized on the Company's Consolidated Balance Sheets are summarized below. The table includes the carrying value, estimated fair value and its placement in the fair value hierarchy as follows: September 30, 2024 Fair Value Measurement (Dollars in thousands) Carrying Fair Value Level 1 Inputs Level 2 Inputs Level 3 Inputs Financial assets: Loans held for sale $ 1,229 $ 1,227 $ — $ 1,227 $ — Loans, net 3,795,286 3,682,641 — — 3,682,641 Financial liabilities: CDs 674,726 675,385 — 675,385 — Borrowed funds 59,949 57,914 — 57,914 — Subordinated debt 59,736 61,059 — 61,059 — December 31, 2023 Fair Value Measurement (Dollars in thousands) Carrying Fair Value Level 1 Inputs Level 2 Inputs Level 3 Inputs Financial assets: Loans held for sale $ 200 $ 201 $ — $ 201 $ — Loans, net 3,508,636 3,353,968 — — 3,353,968 Financial liabilities: CDs 521,076 518,928 — 518,928 — Borrowed funds 25,768 24,081 — 24,081 — Subordinated debt 59,498 55,572 — 55,572 — Excluded from the tables above are certain financial instruments with carrying values that approximated their fair value at the dates indicated, as they were short-term in nature or payable on demand. These include cash and cash equivalents, accrued interest and non-term deposit accounts. The respective carrying values of these instruments would all be classified within Level 1 in the fair value hierarchy.

(the "Company," "Enterprise," "we," or "our") for the year ended December 31, 2023 (the "2023 Annual Report on Form 10-K") as filed with the SEC on March 8, 2024. The Company has not materially changed its significant accounting policies from those disclosed in its 2024 Annual Report on Form 10-K. See Item (b), " Recent Accounting Pronouncements ," below in this Note 1. The accompanying unaudited consolidated interim financial statements of the Company include the accounts of the Company and its wholly owned subsidiary, Enterprise Bank and Trust Company, commonly referred to as Enterprise Bank (the "Bank"). The Bank is a Massachusetts trust company and state chartered commercial bank organized in 1989. Substantially all of the Company's operations are conducted through the Bank and its subsidiaries. The services offered through the Bank and its subsidiaries are managed as one strategic unit and represent the Company's only reportable operating segment.
Organization of the Company and Basis of Presentation - Basis of Accounting	The accompanying unaudited consolidated interim financial statements, and notes thereto, in this Quarterly Report on Form 10-Q for the quarterly period ended September 30, 2024 (this "Form 10-Q"), have been prepared in accordance with U.S. GAAP for interim financial information and the SEC instructions for Quarterly Reports on Form 10-Q. In the opinion of management, the accompanying unaudited consolidated interim financial statements reflect all necessary adjustments, consisting of normal recurring accruals and elimination of intercompany balances, for a fair presentation.
Organization of the Company and Basis of Presentation - Reclassifications	Interim results are not necessarily indicative of results to be expected for the entire year, or any future period.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Accounting pronouncements not yet adopted by the Company In October 2023, the FASB issued ASU 2023-06, "Disclosure Improvements — Codification Amendments in Response to the SEC's Disclosure Update and Simplification Initiative." This ASU amends the ASC to incorporate certain disclosure requirements from SEC Release No. 33-10532, Disclosure Update and Simplification, that was issued in 2018. The effective date for each amendment will be the date on which the SEC's removal of that related disclosure from Regulation S-X or Regulation S-K becomes effective, with early adoption prohibited. ASU 2023-06 is not expected to have a material impact on our consolidated financial statements. In November 2023, the FASB issued ASU 2023-07, "Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures." The amendments in this ASU are intended to improve reportable segment disclosure requirements primarily through enhanced disclosures about significant segment expenses. For public business entities, the amendments are effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. ASU 2023-07 is not expected to have a material impact on our consolidated financial statements. In December 2023, the FASB issued ASU 2023-09, "Income Taxes (Topic 740): Improvements to Income Tax Disclosures." This ASU requires public business entities, on an annual basis, to disclose specific categories in the rate reconciliation and provide additional information for reconciling items that meet a quantitative threshold (if the effect of those reconciling items is equal to or greater than 5 percent of the amount computed by multiplying pretax income by the applicable statutory income tax rate). 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.
