Special Note Regarding Participation by Means of Remote Communication

The ongoing coronavirus (COVID-19) pandemic continues to spread around the world and throughout the United States, including Massachusetts. The health and safety of our shareholders and employees are of paramount concern to the Company’s Board of Directors and management. To minimize the risk to shareholders and employees, the Annual Meeting will be conducted in a “hybrid” meeting format. The Annual Meeting will be held in person at the Enterprise Bank “Community Room,” 18 Palmer Street, Second Floor, Lowell, Massachusetts 01852, and shareholders will also have the option to attend the Annual Meeting by means of remote communication. Instructions for attending and participating in the Annual Meeting by means of remote communication are provided below.

At the Annual Meeting, you will be provided the opportunity to ask questions and vote on matters submitted to shareholders unless you participate via the "listen only" option. Please note that the Chairman of the Annual Meeting will only respond to questions pertinent to the business of the Annual Meeting.

Due to the ongoing coronavirus (COVID-19) pandemic and in accordance with guidance from and recommendations by the Centers from Disease Control and the Massachusetts Department of Public Health, we intend to limit in person attendance in order to ensure adequate social distancing of all in-person attendees at the Annual Meeting. In light of this, we strongly encourage shareholders to participate in the Annual Meeting by means of remote communication, rather than attend the Annual Meeting in person.

Shareholders may participate in the Annual Meeting by means of remote communication in one of two ways:

•In order to view the presentation, vote and ask questions: log onto www.meetnow.global/MCWT9PU with your control number provided on the proxy card; OR

•Listen only: call 1-844-866-7033 with conference ID: 1878952

Those planning to attend and participate in the Annual Meeting by means of remote communication should call in or log onto the Annual Meeting virtual platform at least 15 minutes prior to the start of the Annual Meeting. Shareholders may participate by voting and asking questions at the Annual Meeting by either logging on to the Annual Meeting virtual platform at www.meetnow.global/MCWT9PU with your control number, or by attending in person.

Anyone may enter the Annual Meeting as a guest in listen-only mode at 1-844-866-7033 with conference ID: 1878952 or www.meetnow.global/MCWT9PU , but only shareholders of record and beneficial owners of shares who have registered for the Annual Meeting may attend and participate in the Annual Meeting.

Shareholders of Record. If you are a shareholder of record (i.e., you hold your shares through the Company’s transfer agent, Computershare), then you do not need to register to attend the Annual Meeting by means of remote communication. If you plan to attend the meeting by means of remote communication, shareholders of record will need their control number [located on your proxy card] to vote and ask questions at the Annual Meeting by means of remote communication. Those without a control number may attend as guests of the Annual Meeting by means of remote communication, but they will not have the option to vote their shares during the Annual Meeting or ask questions at the Annual Meeting by means of remote communication.

Beneficial owners. If your shares are held in “street name” (i.e., you hold your shares through an intermediary, such as in a stock brokerage account or by a bank or other nominee), and you would like to ask a question and/or vote your shares at the Annual Meeting then you must register in advance in order to attend the Annual Meeting by means of remote communication. To register, you must submit a legal proxy that reflects your proof of proxy power. The legal proxy must reflect your holdings of shares of Company common stock, along with your name. Please forward a copy of the legal proxy, along with your email address, to Computershare. Requests for registration should be directed to Computershare either by email to legalproxy@computershare.com (forwarding the email from your broker or attaching an image of your legal proxy) or by mail to Computershare, EBTC Legal Proxy, P.O. Box 43001, Providence, RI 02940-3001.

Requests for registration must be labeled as “Legal Proxy” and be received by Computershare no later than April 20, 2022 by mail and no later than April 27, 2022 by email. You will receive a confirmation of your registration by email (or by mail, if no email address is provided) after Computershare receives your registration materials. To attend the Annual Meeting by means of remote communication at www.meetnow.global/MCWT9PU, you will need to enter the control number provided in the confirmation sent by Computershare.

Record Date

The Board of Directors has fixed the close of business on March 1, 2022 as the record date for the determination of shareholders entitled to notice of, and to vote at, the Annual Meeting and any adjournments or postponements thereof (the “Record Date”). Only holders of record of the Company’s common stock (the “Common Stock”) at the close of business on the Record Date will be entitled to vote at the Annual Meeting. At the close of business on the Record Date, there were 12,053,652 shares of Common Stock issued and outstanding. The holders of shares of Common Stock outstanding as of the close of business on the Record Date will be entitled to one vote for each share held of record upon each matter that may properly come before the Annual Meeting or any adjournments or postponements thereof.

Proxies

If you are the record holder of your shares (i.e., you hold your shares in your own name with our transfer agent, Computershare, as opposed to through a bank, broker or other nominee), you may vote at the Annual Meeting in person, by means of remote communication, or by proxy. Proxies may be delivered electronically via the Internet, by telephone, or in writing by mail. If you intend to deliver a proxy electronically or by phone, you may do so by following the instructions included with your proxy card.

If you hold your shares in “street name,” such as in a stock brokerage account or through a bank or other nominee, such bank, broker or other nominee should provide you with these proxy materials, including a voting instruction card. If you hold your shares in “street name” and have not received these proxy materials, including a voting instruction card, from your bank, broker or other nominee, please contact the institution that holds your shares. As a street name shareholder, you may also be eligible to vote your shares via the Internet or by telephone by following the voting instructions provided by the bank, broker or other nominee that holds your shares, using either the Internet address or the toll-free telephone number provided on the voting instruction card (if the bank, broker or other nominee provides these voting methods). Otherwise, please complete, sign and date the voting instruction card and return it promptly.

If you vote electronically or by telephone and you properly follow the instructions included with your proxy card by no later than the deadline indicated in such instructions or if you vote by mail and you return to the Company the enclosed proxy card properly executed in time to be voted at the Annual Meeting, then the shares

represented by your proxy, regardless of the method of delivery, will be voted in accordance with your voting instructions, unless you subsequently revoke your proxy as further explained below.

If you properly deliver your proxy without including any instructions as to how your proxy should be voted, then your proxy will be voted as follows: (1) FOR the election of Kenneth S. Ansin, George L. Duncan, Jacqueline F. Moloney, Luis M. Pedroso, Michael T. Putziger, Carol L. Reid and Nickolas Stavropoulos, as the seven nominees of the Board of Directors, as Directors of the Company, each to serve for a three-year term expiring at the 2025 annual meeting of shareholders or until their respective successors are duly elected and qualified, or until their earlier resignation, death or removal from office; (2) FOR the Say on Pay Proposal; (3) FOR the ratification of the Audit Committee’s appointment of RSM US LLP as the Company’s independent registered public accounting firm for the year ending December 31, 2022; and (4) in such manner as the proxy holders decide on such other matters as may properly come before the Annual Meeting or any adjournments or postponements thereof.

The presence of a shareholder at the Annual Meeting, whether in person or by means of remote communication will not automatically revoke a shareholder’s proxy. A shareholder may, however, revoke a proxy at any time before such proxy is voted at the Annual Meeting by filing with the Secretary of the Company a written notice of revocation, by delivering to the Company a duly executed proxy bearing a later date, or by properly delivering a proxy electronically or by telephone at a later date. All written notices of revocation and other written communications with respect to revocation of proxies in connection with the Annual Meeting should be addressed as follows: Enterprise Bancorp, Inc., 222 Merrimack Street, Lowell, Massachusetts 01852, Attention: John A. Koutsos, Secretary.

It is not anticipated that any matters other than those set forth in Proposals One, Two, and Three will be brought before the Annual Meeting. The Company has not received any proper proposals from its shareholders to be included in this Proxy Statement or otherwise brought before the Annual Meeting. Please see the additional information under the heading “Shareholder Proposals” on page 52 of this Proxy Statement, below, for a description of the requirements that must be satisfied for any Director nomination or other shareholder proposal, which is not otherwise included in this Proxy Statement, to be presented by any shareholder at the Annual Meeting. If any other matters properly come before the Annual Meeting, the persons named as proxies will vote upon such matters in their discretion in accordance with their best judgment.

Proxies may be solicited personally or by mail, telephone, fax or e-mail by officers, Directors and employees of the Company, none of whom will be specially compensated for such solicitation activities. Arrangements will also be made with brokerage houses and other custodians, nominees and fiduciaries for forwarding solicitation materials to the beneficial owners of shares held of record by such persons, and the Company will reimburse such persons for their reasonable out of pocket expenses incurred in connection with that solicitation. The cost of soliciting proxies will be borne by the Company.

Quorum; Vote Required

The presence, whether in person, by means of remote communication, or by proxy, of at least a majority of the total number of outstanding shares of Common Stock is necessary to constitute a quorum at the Annual Meeting for the transaction of business. Abstentions, withheld votes and shares held by a bank, broker or other nominee that are voted on any matter will be counted as present for purposes of determining the presence or absence of a quorum for the transaction of business at the Annual Meeting.

The number of affirmative votes required for approval of the matters to be considered at the Annual Meeting is as follows:

•Proposal One - Election of Class of Directors

Each Director is required to be elected by a majority of the votes cast by shareholders present, whether in person, by means of remote communication, or by proxy, at the Annual Meeting. At the Annual Meeting, the maximum number of Directors to be elected is seven.

•Proposal Two - Approval of the Say on Pay Proposal

The Say on Pay Proposal will be approved on a non-binding advisory basis if the votes cast by shareholders present, whether in person, by means of remote communication, or by proxy, at the Annual Meeting favoring the Say on Pay Proposal exceed the votes cast by shareholders present, in person, by means of remote communication, or by proxy, at the Annual Meeting opposing the Say on Pay Proposal.

•Proposal Three - Ratification of Appointment of Independent Registered Public Accounting Firm

The ratification of the appointment of RSM US LLP as our independent registered public accounting firm for the year ending December 31, 2022 requires that the votes cast by shareholders present, whether in person, by means of remote communication, or by proxy, at the Annual Meeting favoring the ratification exceed the votes cast by shareholders present, in person, by means of remote communication, or by proxy, at the Annual Meeting opposing the ratification.

In voting for the election of Directors, you may vote “FOR” all nominees or “WITHHOLD” your vote from all nominees or from only certain specified nominees. Withholding a vote from all or some of the nominees is effectively a vote against such nominee(s). Under Massachusetts law, an abstention is not considered a vote cast at a meeting and, consequently, abstentions will have no effect on the voting for this proposal.

In voting for the Say on Pay Proposal, you may vote “FOR” or “AGAINST” or you may “ABSTAIN” from voting on the matter. Under Massachusetts law, an abstention is not considered a vote cast at a meeting and, consequently, abstentions will have no effect on the voting for this proposal.

In voting for the ratification of the appointment of RSM US LLP as our independent registered public accounting firm for 2022, you may vote “FOR” or “AGAINST” such ratification or you may “ABSTAIN” from voting on the matter. Under Massachusetts law, an abstention is not considered a vote cast at a meeting and, consequently, abstentions will have no effect on the voting for this proposal.

Under existing stock exchange rules, banks, brokers, or other nominees may vote shares held for a customer in street name on matters that are considered to be “routine” even if they have not received voting instructions from their clients. A broker “non-vote” occurs when a bank, broker, or other nominee has not received voting instructions from a customer and does not vote the customer’s shares either because the matter is not considered routine or because the bank, broker or other nominee does not exercise its prerogative to vote even if the matter is considered routine.

Proposals One and Two, namely the election of Directors and the Say on Pay Proposal, are not considered “routine” matters, which means that if your shares are held in street name, your bank, broker, or other nominee may not vote your shares on this matter unless you provide timely instructions for such voting. Broker non-votes will not be deemed votes cast at the Annual Meeting for Proposals One and Two and as such, will have no effect on the voting for Proposals One and Two. It is, therefore, important that you vote your shares.

Proposal Three, namely the ratification of the appointment of the independent registered public accounting firm, is considered a “routine” matter, which means that if your shares are held in street name, your bank, broker, or other nominee may vote your shares on this matter in its sole discretion if you do not provide timely instructions for voting your shares.

The Directors and executive officers of the Company have indicated that they intend to vote all shares of Common Stock that they are entitled to vote “FOR” Proposals One, Two and Three. On the Record Date, the Directors and executive officers of the Company in the aggregate had the right to vote 1,956,173 shares of Common Stock, representing approximately 16.23% of the outstanding shares of Common Stock as of such date.

PROPOSAL ONE

ELECTION OF CLASS OF DIRECTORS

The Company’s Second Amended and Restated By-Laws (the “By-Laws”) provide that the number of Directors shall be set by a majority vote of the entire Board of Directors. Currently, the number of Directors for the Company is set at 20. Under the Company’s Restated Articles of Organization, as amended, and By-Laws, this number is divided into three classes, as nearly equal in number as possible, with the Directors in each class serving a term of three years and until their respective successors are duly elected and qualified, or until his or her earlier resignation, death or removal from office. As the term of one class expires, a successor class is elected at the annual meeting of shareholders for that year.

At the Annual Meeting, there are seven (7) Directors to be elected for a three year term to serve until the 2025 annual meeting of shareholders and until their respective successors are duly elected and qualified, or until his or her earlier resignation, death or removal from office. The Board of Directors has nominated, upon the recommendation of the Corporate Governance/Nominating Committee of the Board of Directors, each of Kenneth S. Ansin, George L. Duncan, Jacqueline F. Moloney, Luis M. Pedroso, Michael T. Putziger, Carol L. Reid and Nickolas Stavropoulos, for election as a Director for a three-year term to serve until the 2025 annual meeting of shareholders and until their respective successors are duly elected and qualified, or until his or her earlier resignation, death or removal from office.

The Board of Directors believes that all of the above-listed nominees will stand for election and will serve as a Director if elected. However, if any nominee fails to stand for election or is unable or refuses to accept election, the proxies will be voted for the election of such other person or persons as the Board of Directors may recommend. Alternatively, in lieu of designating a substitute, the Board of Directors may reduce the number of Directors.

PROPOSAL TWO

NON-BINDING ADVISORY VOTE ON EXECUTIVE COMPENSATION

In accordance with the Dodd-Frank Wall Street Reform and Consumer Protection Act and Section 14A of the Exchange Act, the Company is providing shareholders the opportunity to endorse or not endorse the Company’s compensation program for our named executive officers as disclosed in this Proxy Statement by voting for or against the resolution set forth below.

Beginning in 2017, the Company previously submitted its Say on Pay Proposals to its shareholders once every three years (in accordance with the results of the advisory shareholder vote held at the Company’s 2017 annual meeting of shareholders to determine the frequency of an advisory vote on named executive officer compensation). However, at the Company’s 2021 annual meeting of shareholders, the Company proposed changing the frequency of such advisory vote to be held on an annual basis. At the 2021 annual meeting of the Company’s shareholders, over 81% of the shares of Common Stock were cast in support of the Company’s proposal to change the frequency of the Say on Pay proposal to be held on an annual basis. Accordingly, the Company will be including the Say on Pay proposal in its proxy statement on an annual basis.

Your vote on this Say on Pay Proposal is strictly advisory in nature and is not binding in any way on the Company, the Board of Directors or the Compensation and Human Resources Committee of the Board of Directors (the “Compensation and Human Resources Committee”). Nonetheless, the Compensation and Human Resources Committee will review the results of the voting, take into account such results when considering future executive compensation arrangements and otherwise making recommendations to the Board of Directors with respect to such matters.

At the 2021 annual meeting of the Company's shareholders, over 81% of the shares of Common Stock were cast in support of the Company's compensation of its named executive officers. The Company believes that its executive compensation program furthers the interests of its shareholders by providing proper incentives to its senior management to achieve both long-term and short-term goals without taking unnecessary or excessive risks that could threaten the Company’s financial condition or prospects. The objectives and design of the Company's compensation program for the named executive officers listed under "Compensation Discussion and Analysis - Overview", including the different components of compensation and the rationale for each component, are described in detail under the heading “Compensation Discussion and Analysis” at pages 26-33 of this Proxy Statement, below. Shareholders are urged to read the “Compensation Discussion and Analysis” section, the accompanying compensation tables and the related narrative disclosure in this Proxy Statement, which more thoroughly discuss the Company’s compensation policies and procedures.

Accordingly, the Company is asking shareholders to vote on the following non-binding advisory resolution:

RESOLVED, that the shareholders of Enterprise Bancorp, Inc. hereby approve, on a non-binding advisory basis, the compensation paid to the Company’s named executive officers, as disclosed in the “Compensation Discussion and Analysis” section, the accompanying compensation tables and the related narrative disclosure in the Company’s Proxy Statement for the 2022 Annual Meeting of Shareholders,

Recommendation of the Board of Directors

The Board of Directors recommends that the shareholders vote FOR this Proposal Two.

PROPOSAL THREE

RATIFICATION OF APPOINTMENT OF INDEPENDENT

REGISTERED PUBLIC ACCOUNTING FIRM

The Audit Committee has appointed RSM US LLP to serve as the independent registered public accounting firm of the Company for the year ending December 31, 2022.

While the Company is not required to submit the ratification of the Audit Committee’s appointment of the Company’s independent registered public accounting firm to a vote of shareholders, the Board of Directors considers the selection of the independent registered public accounting firm to be an important matter and is therefore submitting the selection of RSM US LLP for ratification by shareholders as a matter of good corporate practice.

In the event a majority of the votes cast are against the ratification of the appointment of RSM US LLP, the Audit Committee may consider the vote and the reasons therefor in future decisions of its appointment of the Company’s independent registered public accounting firm. Even if the appointment is ratified, the Audit Committee in its discretion may direct the appointment of a different independent registered public accounting firm at any time if it is determined that such a change would be in the best interests of the Company.

Representatives of RSM US LLP are expected to attend the Annual Meeting, either in person or by means of remote communication, at which time they will have an opportunity to make a statement if they wish to do so and will be available to answer any appropriate questions from shareholders.

The following table sets forth the fees paid or accrued by the Company for professional services provided by the Company’s independent registered public accounting firm, RSM US LLP, for the years indicated.

Messrs. Duncan, Main and Clancy, who are all current employees of the Company, were determined not to be independent of the Company.

Board Leadership Structure and the Board’s Role in Risk Oversight

Mr. Duncan, who through December 31, 2006 served as the Company’s Chief Executive Officer, serves as the Executive Chairman of the Board and Mr. Clancy serves as the Chief Executive Officer of the Company. The Board of Directors has implemented this structure to enhance succession planning for Company management while recognizing the individual roles and responsibilities of the Chief Executive Officer and Executive Chairman and taking into consideration the size, growth potential and complexity of the Company’s operations.

The Board of Directors annually appoints a Chairman, Vice Chairman, Secretary and Assistant Secretary. These Board offices are currently held by Mr. Duncan as Executive Chairman, Mr. Conway as Vice Chairman, Mr. Koutsos as Secretary and Mr. Pedroso as Assistant Secretary. The Board of Directors also annually appoints an independent Lead Director, which Board office is currently held by Mr. Conway. As Lead Director, Mr. Conway presides over executive sessions of independent Directors. In addition to these offices, the Board of Directors maintains active committees to which specific risk oversight responsibilities have been delegated by the Board of Directors. Committee chairpersons and members are elected each year by the Board of Directors to a one-year term.

Regular meetings of the Board of Directors and its committees are held to review strategy, policy and results of operations, including discussions of risk. The frequency of meetings is determined by, among other things, strategy, operations and the number and significance of risk matters that are discussed at either the Board or committee meetings. Each committee chairperson is provided an opportunity to present a report to the full Board of Directors at each regularly scheduled Board meeting and is required to provide a full report of past accomplishments and future strategies to the full Board of Directors on an annual basis.

The Board of Directors is responsible for oversight of the Company’s risk management. The Chief Executive Officer, the Company’s Executive Vice President-Chief Risk Officer and other members of senior management provide regular reports to the Board on the Company’s management of risk. Additionally, on a semi-annual basis, the Company’s Chief Risk Officer reports to the Board of Directors on the effectiveness of the Company’s risk management program.

Board Self-Assessments

The Board of Directors has committed to regularly assessing its own performance to identify the strengths of the Board of Directors as well as areas in which the Board of Directors may improve performance or focus its attention. The Board of Directors anticipates that the self-assessment processes will occur on an annual basis, at both the full Board-level as well as the committee-level. The purpose of the self-assessment is to improve the functioning of the Board of Directors as a whole, and not to target the performance of any individual director.

The self-evaluation process, which is established by the Corporate Governance Nominating Committee of the Board of Directors, involves the completion of annual evaluations for each committee and the full Board, review and discussion of the results of the evaluations by both the committee and the full Board and the consideration of actions to address any issues. As a result of the 2021 assessment, the Board of Directors has focused and will continue to focus on director education and development, strategy development, identifying and following best governance practices, holding effective virtual meetings, and assessing board skills.

The Board and each of the committees of the Board of Directors conducted their self-assessments in 2021 and will continue to conduct annual self-assessments in the future.

Meetings of Board of Directors and Committees

There were eleven meetings of the Board of Directors during the year ended December 31, 2021. During such period, each director attended more than 75% in the aggregate of the total number of meetings of the Board of Directors and of each of the committees of the Board of Directors on which he or she served, excluding Mr. Stavropoulos.

During 2021, the Executive Committee provided oversight in the strategy for investments and excess liquidity realized as a result of customer deposits related to the Paycheck Protection Program and changing customer behaviors during the pandemic.

Loan Committee. The overall mission of the Loan Committee is to monitor the trends in asset and credit quality of the Bank's loan portfolio as well as various other internal and external factors and controls that may impact loan growth, quality, concentration risk and overall credit risk exposure.

In addition to these duties, the Loan Committee is responsible for reviewing the results of third-party loan review engagements, monitoring non-performing past due loans and the adequacy of the allowance for credit losses for loans and reserves for unfunded commitments, including the methodology applied to calculate the level of the allowance for credit losses for loans and reserves for unfunded commitments. The Loan Committee not only identifies and informs the Board of Directors of any unfavorable trends that it may detect in the Bank’s loan portfolio, but also recommends actions that may be taken to mitigate portfolio risk reviewing and approving charge-offs. Over the past year, the Loan Committee discussed; loan forgiveness under the Paycheck Protection Program, loan concentrations within industries impacted by the pandemic, the potential volume of deferred payments and past due loans, additions to the Allowance for Credit Losses, stress testing focused on COVID impacted industries, and other credit risks as a result of COVID - 19.

Board Attendance at Annual Meetings

Directors are required to attend each of the Company’s annual meetings of shareholders. Absences will be allowed for serious personal or business obligations that cannot be rescheduled. All Directors attended the 2021 annual meeting of shareholders that was held virtually.

DIRECTOR COMPENSATION

All members of the Board of Directors are Directors of the Company and of the Bank. In 2021, non-employee Directors were compensated per month based on their Committee membership and the annual retainer listed below, excluding Executive Committee meetings, which members were paid $700 per meeting. In 2021,

non-employee Directors were paid a monthly cash retainer of $1,925 for Board of Directors meetings, excluding the Board's annual strategic planning meetings, for which they were paid $1,000 for each meeting. Also in 2021, any new Directors will be paid a New Director Committee Orientation fee of $650 per month for attendance at any and all Committee meetings attended for the duration of the orientation period.

Non-employee Directors also receive fees as detailed in the following table:


			Annual Retainer

(1) This amount reflects the 2021 annual cash retainer of $15,600 and awards of shares of restricted stock with a grant date value of $15,613 per non-employee Director. The shares of restricted stock granted to non-employee Directors as part of their 2021 annual retainers generally vest over a two-year period. In 2021, an aggregate of 8,109 shares of restricted stock were granted to non-employee Directors as part of their 2021 annual retainer. All other annual retainers are paid in cash unless the Director has elected to receive shares of Common Stock.

(2) This annual retainer is paid only when the Loan Committee Chairperson is a non-employee Director.

In 2021, all annual retainers paid in cash were paid in equal monthly installments.

Directors who are also full-time salaried officers of the Bank were not paid for attending Board of Directors or committee meetings in 2021 and did not receive retainers of any kind for their services in any capacity as Directors.

For the year 2021, non-employee Directors had the option to make an irrevocable election (by December 31, 2020) to receive shares of Common Stock in lieu of receiving all or a portion of their 2021

compensation in cash. The number of shares issued to non-employee Directors pursuant to this election is based on an average of the quarterly close price of the Company’s Common Stock on the NASDAQ Global Market in 2021. For the year 2021, the Company issued a total of 7,375 shares of Common Stock to seven non-employee Directors at a per share issuance price of $34.14. These shares were issued in January 2022. For the year 2022, non-employee Directors have the same option to receive shares of Common Stock in lieu of cash fees. These shares will be issued in January 2023.

The Company believes that giving non-employee Directors the option to receive shares of Common Stock in lieu of cash fees and granting to them restricted stock awards with time-vesting requirements further aligns such Directors’ interests with those of the Company’s shareholders.

The following table details the total compensation paid to each non-employee Director for the year ended December 31, 2021.

COMPENSATION DISCUSSION AND ANALYSIS

Overview

This section details the Company’s executive compensation philosophy and contains a discussion of each material element of the Company’s executive compensation program as it relates to the following “named executive officers” of the Company (the “Named Executive Officers”) whose compensation information is detailed below:

George L. Duncan Executive Chairman

John P. Clancy, Jr. Chief Executive Officer

Richard W. Main President

Joseph R. Lussier Chief Financial Officer and Treasurer

Stephen J. Irish Managing Director of Wealth Management and Chief Operating Officer

Executive Compensation Philosophy and Objectives

The Company’s executive compensation program is designed to attract, motivate, and retain highly qualified executive officers, who are vital to achieving the financial goals set by the Board of Directors and enhancing long-term value for shareholders, while operating the Company in a safe and sound manner. The Company’s executive compensation philosophy provides that total annual compensation levels should:

(1) reflect compensation levels of those found in other banking organizations of comparable asset size, performance and geography;

(2) reflect individual responsibilities, team contribution, team leadership, experience, skill set, teamwork and performance; and

(3) provide incentive to achieve business and financial objectives within reasonable risk parameters.

The Company at least annually assesses total compensation paid to its executive officers. As part of this process, the Compensation and Human Resources Committee has assessed and evaluated the elements of total compensation described below under the 2021 Executive Compensation Program paid to executive officers, including the Named Executive Officers, as a group and individually.

Compensation and Human Resources Committee and Independent Consultant Roles

Consistent with our above described philosophy, the Compensation and Human Resources Committee regularly obtains and considers information regarding compensation levels in the Company’s industry through various sources, including compensation surveys conducted by banking industry associations and independent compensation consultants. The Compensation and Human Resources Committee also reviews annually the responsibilities and performance of the Company’s executive officers. Elements of compensation are established with the goal of incentivizing and rewarding the Company’s executive officers for individual performance and organizational short- and long-term goals without encouraging excessive risk-taking.

In accordance with the Compensation and Human Resources Committee Charter, the Compensation and Human Resources Committee follows the process outlined under the heading “Role of the Compensation and Human Resources Committee” as described further under Compensation and Human Resources Committee Matters on page 34 below.

The Compensation and Human Resources Committee annually engages a compensation consulting firm to review the elements of the Company’s executive compensation program and to provide comparative market information on total executive compensation including base salary, incentive cash compensation, and incentive equity compensation for the Compensation and Human Resources Committee’s review. The Compensation and Human Resources Committee engaged Pearl Meyer and Partners (“Pearl Meyer”) to conduct a comparative market review of the Company’s executive compensation programs and develop the peer group for the year ended December 31, 2021. In addition to general survey data provided by Pearl Meyer, a peer group was developed consisting of publicly traded bank holding companies within the Northeast region of the United States, including companies located in the states of New York, New Jersey, and Pennsylvania, ideally in metropolitan locations, with similar asset size and performance results to the Company and, like the Company, with a loan portfolio substantially consisting of commercial loans, as well as, wealth management business. At the time the peer group was selected, the Company was positioned at approximately the median of the peer group in terms of total assets, with total asset size of the peer group ranging from $2.2 billion to $8.8 billion. The information was not gathered to benchmark executive compensation to particular levels within the peer and survey group; rather, it was reviewed to assess the competitiveness of the Company’s total executive compensation. For the year ended December 31, 2022, the Compensation and Human Resources Committee again engaged Pearl Meyer to assess the Company’s 2022 executive compensation program.

Working with Pearl Meyer, the Compensation and Human Resources Committee selected the following peer group:


Lakeland Bancorp, Inc.			ConnectOne Bancorp, Inc.
Univest Financial Corporation			Peapack-Gladstone Financial Corporation
Washington Trust Bancorp, Inc.			Financial Institutions, Inc.
Camden National Corporation			Republic First Bancorp, Inc.
CNB Financial Corporation			HarborOne Bancorp, Inc.
Cambridge Bancorp			The First of Long Island Corporation
Bar Harbor Bankshares			Mid Penn Bancorp, Inc.
Peoples Financial Services Corp.			BCB Bancorp, Inc.
Orrstown Financial Services, Inc.			The First Bancorp, Inc.
Western New England Bancorp, Inc.			Chemung Financial Corporation
Codorus Valley Bancorp, Inc.

Compensation Elements and Rationale

Executive compensation may include any or a combination of the following components in addition to an executive’s base salary: incentive cash compensation, incentive equity awards, supplemental executive retirement benefits, supplemental life insurance benefits, income protection following a termination of employment under various circumstances, including following a change in control of the Company, and other perquisites such as Company-owned automobiles and club memberships for business development purposes. Each of these components is reviewed, both separately and from a total compensation perspective, and approved by the Compensation and Human Resources Committee and the independent members of the Board of Directors on at least an annual basis. The Company believes that by using a combination of these elements it is best able to find an effective balance in motivating each executive to achieve long-term and short-term goals without taking unnecessary or excessive risks that could threaten the Company’s financial condition or prospects, thereby enhancing long-term shareholder value. In establishing the components of compensation for each individual executive officer, the Compensation and Human Resources Committee considers the performance and responsibilities of the individual, the executive’s designation or role within the Company, the cost to the Company of the various components of compensation to be provided, the tax and accounting implications in designing the Company’s compensation programs, and the support received from the Company’s shareholders in prior non-binding “Say on Pay” advisory votes. The Compensation and Human Resources Committee did not change its approach in 2022 and applied a rationale similar to that used in 2021. The Compensation and Human Resources Committee will continue to consider the outcome of the Company’s non-binding “Say on Pay” advisory votes when making future compensation decisions for the Named Executive Officers.

2021 Executive Compensation Program

Base Salary

For the year ended December 31, 2021, the Compensation and Human Resources Committee reviewed the various components of the compensation provided to each Named Executive Officer, assessed each Named Executive Officer’s responsibilities, leadership, overall performance, and contributions, and reviewed the comparative assessment provided by Pearl Meyer. The Compensation and Human Resources Committee then determined that the base salaries of Messrs. Duncan, Main, and Clancy for 2021 would remain unchanged from 2020 levels. In March 2021, the Compensation and Human Resources Committee also determined that the base salaries for Messrs. Irish and Lussier for 2021 would be increased as follows: Mr. Irish from $355,414 to $366,076, and Mr. Lussier from $214,000 to $246,100.

For the year ending December 31, 2022, the Compensation and Human Resources Committee did not change its approach in determining base salaries for the Named Executive Officers and applied a rationale similar to that used in the prior year. The Compensation and Human Resources Committee determined that the base

salaries for Messrs. Irish and Lussier would increase from 2021 levels, in part, to maintain alignment with the competitive range of base salaries found in the peer group for their positions. The base salary increases for Messrs. Irish and Lussier effective March 2022 are as follows: Mr. Irish from $366,076 to $378,889 and for Mr. Lussier from $246,100 to $270,710. The Compensation and Human Resources Committee determined that the base salaries for Messrs. Duncan, Main and Clancy will remain unchanged for 2022.

Incentive Compensation (Cash)

The terms of incentive cash compensation for Named Executive Officers are established by the Compensation and Human Resources Committee, subject to approval by the independent members of the Board of Directors, on an annual basis. Named Executive Officers are eligible for incentive cash compensation through the Company’s Variable Compensation Incentive Plan that is established each year by the Compensation and Human Resources Committee. Due to the continued uncertainty of the ongoing COVID-19 pandemic in 2021, the Compensation and Human Resources Committee determined to use one metric for measuring the Company’s performance when designing the 2021 Variable Compensation Plan. Payments for Named Executive Officers under the 2021 Variable Compensation Incentive Plan was determined by the Company’s performance in attaining “Income” (as defined below) targets with an adjustor for the provision for credit losses. Target incentive payout percentages for Named Executive Officer’s base compensation earned under the 2021 Variable Compensation Incentive Plan were 45% for Messrs. Duncan and Main, 50% for Mr. Clancy, 37.5% for Mr. Irish, and 30% for Mr. Lussier.

The 2021 Variable Compensation Incentive Plan was based on the Company’s performance in attaining “Income” (as defined below) with an adjustor for the provision for credit losses. The 2021 Variable Compensation Incentive Plan, including the performance levels, are shown in the table below.

“Income,” as used above, was defined as the Company’s pre-tax income excluding variable compensation plan expense, the provision for credit losses, gains or losses on sales of investment securities, losses on the prepayment of borrowings or subordinated debt, and gains or losses on the early termination of hedged transactions. If the Company’s actual provision for credit losses is at budget of $9 million, there will be no adjustment to the Income performance factor results. Every dollar that the Company’s provision for credit losses exceeds budget, the amount above $9 million is multiplied by 75% and applied as reduction to the “Income” performance factor results. There was no adjustment for the provision for credit losses as it did not exceed budget. In the fourth quarter the Bank realized a gain on the sale of OREO of $1.1 million and this transaction was also excluded from the Plan results.

In February 2022, the Compensation and Human Resources Committee approved payouts under the 2021 Variable Compensation Incentive Plan for the Named Executive Officers. Messrs. Duncan and Main received an actual payout of 60.3%, which resulted in the following cash payments: $258,373 for Mr. Duncan and $193,780 for Mr. Main. Mr. Clancy received an actual payout of 67%, which resulted in a cash payment of $352,382. Mr. Irish earned an actual payout of 50.25%, which resulted in a cash payment of $187,716, including an additional amount of $5,000 for leadership during the pandemic in 2021. Mr. Lussier earned an actual payout of 40.2%, which resulted in a cash payment of $100,954, including an additional amount of $5,000 for leadership during the pandemic in 2021. The Board of Directors established the Company’s 2022 Variable Compensation Incentive Plan in March 2022 for each of the Named Executive Officers. The Board of Directors approved performance targets and percentage payout amounts for 2022 for each of the Named Executive Officers. On March 15, 2022 the Board of Directors approved the target payout percentages for Messrs. Duncan, Main, and Clancy, which

remained unchanged from 2021 levels and were as follows: Mr. Clancy at 50%; Messrs. Duncan and Main at 45% and approved increases for Mr. Irish from 37.50% to 40% and Mr. Lussier from 30% to 32.5% of their actual annual regular earnings.

Long-Term (Equity) Incentive Compensation

The Company attempts to align the interests of its executives with the long-term interests of shareholders through the granting of equity-based compensation awards, which have historically been in the form of stock options and restricted stock. Equity awards are intended to (1) enhance management’s sense of ownership and commitment to the long-term success of the Company, (2) encourage and reward management performance that increases the long-term success and shareholder value of the Company, and (3) attract and retain the senior leadership and management talent the Company needs to be successful. At this time, the Compensation and Human Resources Committee anticipates that restricted stock, as well as stock options, will continue to serve as the primary vehicles to be used to achieve these objectives.

In connection with its compensation program, the Compensation and Human Resources Committee evaluates the issuance of equity grants to employees on an annual basis. Historically, equity grants have been considered and made during the first quarter of each calendar year. The total number of stock options or restricted stock granted to all employees is determined after considering various factors, including measures on shareholder dilution, such as overhang and run rate. The number of stock options or the value of restricted stock awards granted to individual employees, including the Named Executive Officers, is also based upon various factors, but is primarily based upon an employee’s level of responsibility and individual performance and contribution, and, with respect to the Named Executive Officers and other senior management, the desired mix of compensation. Stock options and restricted stock grants for employees other than the Named Executive Officers and other senior management are recommended by the Chief Executive Officer and the total grant is subject to the approval of the Compensation and Human Resources Committee and the Board of Directors. In addition to the recommendation of the Chief Executive Officer and the approval of the Compensation and Human Resources Committee, stock options and restricted stock awards granted to the Named Executive Officers and other senior management must also be approved by independent members of the Board of Directors. In all cases, the exercise price of the stock options and the value of the restricted stock is established based on the market price of the Company’s common stock on the date of the grant.

On March 17, 2021, the Company granted to employees a total of 17,385 non-qualified stock options at an exercise price of $32.73 per share, which reflected the market price of the Company’s common stock on the date of the grant, and 45,479 shares of restricted stock. On March 17, 2021, the Named Executive Officers received the following equity grants under the Enterprise Bancorp, Inc. 2016 Stock Incentive Plan: 2,046 stock options and 4,233 shares of restricted stock to Mr. Duncan; 1,981 stock options and 4,097 shares of restricted stock to Mr. Clancy; 1,093 stock options and 2,259 shares of restricted stock to Mr. Main; 691 stock options and 1,428 shares of restricted stock to Mr. Irish; and 345 stock options and 714 shares of restricted stock to Mr. Lussier. The shares of restricted stock will vest based on the Company reaching the specific targets in cumulative earnings per share totals set forth on page 39 below. Specific incremental targets were set to align the Named Executive Officers and other senior management with shareholder interests by requiring earnings targets be met for awards to vest rather than incremental time-based vesting. If such targets are not met by December 31, 2025, unvested shares will be forfeited. The stock options, all of which are non-qualified stock options, have an exercise price of $32.73 per share, which reflected the market price of the Company’s common stock on the date of grant, and will vest 50% on the second anniversary of the date of grant and 50% on the fourth anniversary of the date of grant. The Compensation and Human Resources Committee believes the equity grant vesting schedules are aligned with the Company’s long-term performance goals.

The number of stock options and shares of restricted stock granted to the Named Executive Officers during the year ended December 31, 2021 were considered to be within the competitive ranges for executive management based on the assessment received from Pearl Meyer, and the Compensation and Human Resources

Committee believes such equity grants meet the Company’s objective of executive employee participation in the Company’s equity compensation program, aligning the Named Executive Officers’ interests with those of the shareholders.

On March 15, 2022, the Company granted to employees a total of 16,797 non-qualified stock options at an exercise price of $38.58 per share, which reflected the market price of the Company’s common stock on the date of the grant, and 43,808 shares of restricted stock. All options and shares of restricted stock were granted under the Enterprise Bancorp, Inc. 2016 Stock Incentive Plan. For the Named Executive Officers and certain other specific senior employees, restricted stock grants will vest based on the Company reaching specific targets in cumulative earnings per share totals. For all other employees, restricted stock grants will vest 25% per year beginning on the first anniversary of the grant date. Stock option grants to both Named Executive Officers and other employees will vest 50% on the second anniversary of the date of grant and 50% on the fourth anniversary of the date of grant. The Compensation and Human Resources Committee believes the equity grant vesting schedules are aligned with the Company’s long-term performance goals.

The amounts granted to the Named Executive Officers in March 2022 were as follows: 1,698 stock options and 3,591 shares of restricted stock to Mr. Duncan; 2,165 stock options and 4,577 shares of restricted stock to Mr. Clancy; 908 stock options and 1,916 shares of restricted stock to Mr. Main; 677 stock options and 1,432 shares of restricted stock to Mr. Irish; and 391 stock options and 826 shares of restricted stock to Mr. Lussier. The value of stock options and shares of restricted stock granted to the Named Executive Officers in March 2022 was considered to be within the competitive ranges for executive management based on the report provided by Pearl Meyer, and the Compensation and Human Resources Committee believes such equity grants meet the Company’s objective of executive employee participation in the Company’s equity compensation program, aligning the executives’ interests with those of the shareholders.

Supplemental Retirement Benefit and Supplemental Life Insurance Benefit

The Compensation and Human Resources Committee believes that providing a supplemental retirement benefit, which is implemented through salary continuation agreements, a supplemental executive retirement and deferred compensation benefit, and supplemental life insurance benefits serve as long-term retention tools, as well as provide a reward component to the executive.

The Bank is party to certain salary continuation and supplemental life insurance agreements with each of Messrs. Duncan and Main. The terms of these salary continuation agreements, and the annual amounts payable to the executives thereunder, are described further at page 46 below. The annual expense incurred by the Company in maintaining this supplemental retirement benefit for each executive equals the annual increase of the present value of the accumulated benefit to be paid to the executive. This amount is included for each of the executives in the Summary Compensation Table at page 36 below under the heading “Change in Pension Value and Nonqualified Deferred Compensation Earnings.”

The supplemental life insurance benefits that are payable to Messrs. Duncan and Main are included in the amounts shown as payable in the event of death in the table at page 46 below and are specifically referenced in footnote 3 to the table. In 2006, 2015, and 2021 the Company initiated a supplemental life insurance benefit plan for a number of its employees in management positions. Under these plans, the Company has provided supplemental life insurance benefits to the employees, subject to certain restrictions. Messrs. Clancy and Irish participate in both the 2006, 2015, and 2021 plans and Mr. Lussier participates in the 2015 and 2021 plans. The amounts of their supplemental life insurance benefits are included in the amounts shown as payable in the event of death in the table at page 46 below and are specifically referenced in footnote 3 to the table.

In March 2021, the Compensation and Human Resources Committee and the Board of Directors approved contributions to the Enterprise Bank Supplemental Executive Retirement and Deferred Compensation Plan, as amended (“SERP”), for certain Named Executive Officers, including Messrs. Clancy, Lussier and Irish. Under the terms of the SERP, Company contributions to the SERP were made in February 2022 for the 2021 plan year for

the following individuals: $193,000 for Mr. Clancy, $23,520 for Mr. Lussier, and $34,520 for Mr. Irish. The Named Executive Officers direct the investments of their individual accounts. Messrs. Clancy, Lussier, and Irish’s account balances will be paid out, subject to the terms of the SERP, as a lump sum or in monthly installment payments over a period of sixty (60) months following six (6) months after separation from service in accordance with Section 409A of the Internal Revenue Code of 1986 (the “Code”). Benefits under the SERP are paid from the Bank’s general assets, although the Company also maintains a Rabbi Trust. The Rabbi Trust and the funds held therein are Company assets. Employer contributions made to the SERP will become 50% vested after four years and 100% after six years from when the Named Executive Officer became eligible for the SERP or become 100% vested upon attaining age 62(1). All plan benefits associated with employer contributions would be forfeited if the employee is terminated for cause.

Messrs. Clancy, Lussier, and Irish will be eligible for service-based and performance-based plan contributions to the SERP for the 2022 plan year.

Income Protection and Non-Compete

In addition to the above-noted elements of compensation, Messrs. Duncan, Main and Clancy have written employment agreements with the Company, which include non-competition restrictions, and Messrs. Irish and Lussier have written change in control/non-competition agreements with the Company. These agreements provide the respective Named Executive Officers with income protection in the event of a termination of his employment under certain circumstances, including following a change in control of the Company. The Compensation and Human Resources Committee believes these agreements are an important tool in retaining key executives while providing protection to the Company by restricting the executive’s ability to compete in the Company’s marketplace if he or she were to leave prior to or as a result of any change in control of the Company. The Compensation and Human Resources Committee believes that the non-competition protection afforded by these agreements is beneficial in the Company’s competitive marketplace and that the payment amounts and related conditions thereto contained in the agreements are consistent with reasonable industry standards. The maximum amounts that may be paid to any Named Executive Officer under any of these agreements are limited by automatic “cutback” provisions that ensure payments will not exceed the limits specified under Section 280G of the Code. The terms of these agreements are described at pages 42-44 below and the amounts payable thereunder to the Named Executive Officers under various termination scenarios are included in the table at page 46 below.

Perquisites

In addition to their participation in the Company’s general employee benefit plans, as described in footnote 6 of the Summary Compensation Table at page 36 below, the Company provides Company-owned automobiles for the use of Messrs. Duncan, Main and Clancy. The Company also pays dues related to club memberships for business development purposes for Messrs. Main and Clancy. The Compensation and Human Resources Committee believes that the cost of these additional perquisites is modest for the size of the Company and that providing them is consistent with maintaining a competitive total compensation and benefits package for senior management and for business development purposes.

(1) Under terms of the SERP, contributions would vest if employee "separates from services" with Company after reaching "Normal Retirement Age" of 62.

Policies & Practices

Executive Officers and Directors Stock Ownership Guidelines

The Company has established stock ownership guidelines for its executive officers and directors. The Company believes that the executive officer and director stock ownership guidelines further strengthen the individual’s commitment to the Company’s future and further aligns their interests with those of the Company’s shareholders. The Company’s executive officers and directors are required to meet the specific stock ownership guidelines as listed below. The individual will be required to meet the stock ownership guidelines within five years of being hired or promoted to an executive officer position or elected as a director of the Company or from the implementation date of the guidelines.


Position			Stock Ownership Guideline
Executive Chairman and Chief Executive Officer			Three times base salary at date of calculation
President			Two times base salary at date of calculation
Executive Officer			One time base salary at date of calculation
Director			Five times total Board of Director cash and equity retainer

Ownership is calculated on the last business day of the calendar year using the closing price or book value of the Company’s common stock, whichever is greater, and includes: shares owned outright individually or as a co-owner with a spouse, including those in the Company’s 401(k) plan self-directed brokerage account or the Company’s Employee Stock Purchase Plan; shares owned but held in trust or in the name of an immediate family member; unvested restricted shares; and 60% of the difference between the market price and the exercise price of the employee’s vested stock options under Enterprise Bancorp’s 2009 and 2016 Stock Incentive Plans.

As of December 31, 2021, all directors and executive officers of the Company met or exceeded the above-listed ownership guidelines.

Incentive Compensation Recovery

In order to further align management’s interests with the interests of the Company’s shareholders and support good governance practices, all incentive compensation awards made to officers of the Company with a title of "senior vice president" or a more senior position include a clawback provision. If the Company’s reported financial or operating results are determined by the Company to be subject to material negative restatement due to material noncompliance with any financial reporting requirement under the securities laws, fraud, or misconduct (other than a restatement caused by a change in applicable accounting rules or interpretations), the Company may require recoupment of full or partial payouts made under the short- and long-term compensation plans to participants with an officer status of senior vice president or above.

Anti-Hedging Policy

The Board of Directors has adopted, as part of the Company’s Insider Trading Policy, a policy prohibiting the Company's directors, executive officers and employees from engaging in hedging activities involving the Company’s common stock by making an investment to reduce the risk of adverse price movements in the Company’s common stock.

COMPENSATION AND HUMAN RESOURCES COMMITTEE MATTERS

Role of the Compensation and Human Resources Committee

The Compensation and Human Resources Committee of the Board of Directors is comprised of five members, all of whom are currently determined to be independent by the Board of Directors. In determining the independence of the members of the Compensation and Human Resources Committee, the Board of Directors has used the definition of (i) “independence” contained in Rule 5605(d)(2)(A) of the Marketplace Rules of the NASDAQ Stock Market, and (ii) “non-employee directors” within the meaning of Exchange Act Rule 16b-3 and has applied these definitions consistently to all members of the Compensation and Human Resources Committee. One responsibility of the Compensation and Human Resources Committee is to review the performance of the Executive Chairman and recommend his compensation to the independent members of the Board of Directors for review and approval. The Executive Chairman and Compensation and Human Resources Committee review the performance of the Chief Executive Officer and President and recommend their compensation to the independent members of the Board of Directors for review and approval. The Company’s Chief Executive Officer evaluates the performance of the remaining executive officers and recommends their compensation to the Compensation and Human Resources Committee. The Compensation and Human Resources Committee reviews the Chief Executive Officer’s recommendations and submits its recommendation to the independent members of the Board of Directors for approval. In March 2021, the independent members of the Board of Directors approved all recommendations presented by the Compensation and Human Resources Committee.

The Compensation and Human Resources Committee has the authority to retain or obtain advice from independent advisors, such as outside legal counsel and consulting firms, as it deems necessary to perform its role. After taking into consideration the factors set forth in NASDAQ Marketplace Rule 5605(d)(3)(D), the Compensation and Human Resources Committee obtained the services of Pearl Meyer during the year ended December 31, 2021 to provide market assessment information to the Compensation and Human Resources Committee which is discussed in further detail in the Company’s Compensation Discussion and Analysis at pages 26-33 above. Pearl Meyer was paid $29,200 for these services during the year ended December 31, 2021. The Compensation and Human Resources Committee reviewed all factors, as provided by management, for any potential or actual conflicts of interest with Pearl Meyer and the Board of Directors or the Company and determined there were no potential or actual conflicts with the Board of Directors or the Company.

The Compensation and Human Resources Committee operates under a written charter, a copy of which can be found on the Company’s website (www.enterprisebanking.com). The Compensation and Human Resources Committee annually reviews its charter and recommends any changes to the full Board of Directors. The charter requires the Compensation and Human Resources Committee to meet at least four times every year. During the year ended December 31, 2021, the Compensation and Human Resources Committee met seven times.

Compensation and Human Resources Committee Report

The Compensation and Human Resources Committee has reviewed and discussed the Company’s Compensation Discussion and Analysis contained at pages 26-33 above (the “CD&A”) with management and based on this review and discussion the Compensation and Human Resources Committee has recommended to the Board of Directors that the CD&A be included in this Proxy Statement.

None of these Directors has had any relationship with the Company that would require disclosure in this Proxy Statement under the heading “Transactions with Certain Related Persons” at page 49 below under applicable SEC rules.

Risk Assessment of Compensation Policies and Practices

The Company has implemented an annual risk assessment of its compensation policies and practices, which is intended to determine whether any of its existing compensation policies or practices create incentives for taking unnecessary or excessive risks that are reasonably likely to have a material adverse effect on the Company. On the basis of its 2021 annual assessment, the Compensation and Human Resources Committee has determined that no changes to the Company’s existing compensation policies and practices are necessary at this time.

2.The value of the bonus payments received by Mr. Irish and Mr. Lussier in 2020 includes a team appreciation incentive bonus and vacation sell back earnings.

3.The value of the stock awards is based on the fair market value of the Common Stock on the date of grant. The fair market value was calculated as the closing price of the Common Stock on the NASDAQ Global Market on the date of grant, March 16, 2021, which equaled $32.73 per share.

4.The value of the option awards is based on the fair market value of the awards as calculated using the Black-Scholes option valuation model. For assumptions used in calculating the value of option awards and the accounting treatment of the awards, please refer to Note 14 of the financial statements included with the Company’s Annual Report on Form 10-K for the year ended December 31, 2021 as filed with the SEC on March 10, 2022.

In 2021, the discount rate used to determine the present value of the accumulated benefit was unchanged from 3.25% in 2020 resulting in no change to the value for Messrs. Duncan and Main. In 2020, the discount rate used to determine the present value of the accumulated benefit was updated to 3.25% from 4.00% in 2019 resulting in the value to the employee increasing $35,180 and $31,438 for Messrs. Duncan and Main, respectively. In 2019, the discount rate used to determine the present value of the accumulated benefit was updated to 4.00% from 4.75% in 2018 resulting in the value to the employee increasing $39,600 and $34,193 for Messrs.

Pay Ratio Disclosure for Enterprise Bancorp, Inc.

As required by Item 402(u) of Regulation S-K, we are providing the following information:

•The annual total compensation for the median employee of our company (other than Mr. Clancy) was $64,802; and

•The annual total compensation of Mr. Clancy, our Chief Executive Officer, was $1,276,834.

Based on this information, the ratio for 2021 of the annual total compensation of the Chief Executive Officer to the median of the annual total compensation of all employees is 20 to 1.

For the fiscal year ended December 31, 2021, we completed the following steps to identify the median of the annual total compensation of all our employees and to determine the annual total compensation of our median employee and Chief Executive Officer:

1.As of October 2, 2021, our employee population consisted of approximately 550 employees, including all full-time, part-time, temporary, or seasonal employees employed on that date.

2. To find the median of the annual total compensation of all our employees, (other than our Chief Executive Officer), we used wages from our payroll records as reported to the Internal Revenue Service on Form W-2 for fiscal year ended December 31, 2021. In making this determination, we annualized the compensation of full-time and part-time permanent employees who were employed on October 2, 2021 but did not work for us the entire year. No full-time equivalent adjustments were made for part time employees.

3. We identified our median employee using this compensation measure and methodology, which was consistently applied to all our employees included in the calculation.

4. After identifying the median employee, we added together all of the elements of such employee’s compensation for the year ended December 31, 2021 in accordance with the requirements of Item 402(c)(2)(x) of Regulation S-K, resulting in annual total compensation of $64,802. A different median

employee was identified for fiscal year ended December 31, 2021 than the median employee for fiscal year ended December 31, 2020, due to the resignation of the 2020 median employee.

5. With respect to the annual total compensation of our Chief Executive Officer, we used the amount reported in the “Total” column of our Summary Compensation Table.

AGREEMENTS WITH NAMED EXECUTIVE OFFICERS

The Company and the Bank are parties to employment agreements with Messrs. Duncan, Main and Clancy and change in control/noncompetition agreements with Messrs. Irish and Lussier. The Bank is also a party to salary continuation agreements with Messrs. Duncan and Main and supplemental life insurance agreements with Messrs. Duncan, Main, Clancy, Irish and Lussier.

Each of the employment agreements with Messrs. Duncan, Main and Clancy is for a fixed term of three years, subject to an automatic “rolling” renewal each year, unless either the Company or the executive provides a notice of non-renewal, in which case the agreement will expire at the end of the then-current term. Each of

Messrs. Duncan, Main and Clancy is guaranteed a minimum base salary under the terms of his employment agreement: $400,000 for Mr. Duncan; $300,000 for Mr. Main; and $475,000 for Mr. Clancy. At least annually, these amounts are reviewed for increases by the Board. Additionally, Messrs. Duncan, Main, and Clancy are guaranteed minimum target total direct compensation, including base salary, target incentive bonus opportunity, and equity grant value: $720,000 for Mr. Duncan, $505,000 for Mr. Main, and $845,000 for Mr. Clancy. Actual total direct compensation will vary based on the Bank’s performance.

The amount of severance payments and benefits, if any, which may be due to any of the named executive officers under any of the agreements referenced above following any form of termination of the executive is summarized generally below and is further quantified in the table at page 46 of this Proxy Statement, below.

Under the employment agreements with Messrs. Duncan, Main and Clancy, if the executive dies or for Messrs. Duncan and Main is terminated at any time as a result of his long-term disability (as defined in the agreement), the executive or his beneficiary will be paid a lump sum equal to his highest annual compensation (as defined in the agreement to include the sum of the executive’s highest annual base salary and highest annual cash bonus paid at any time prior to the date of termination since January 1, 2004). Upon termination for disability, Messrs. Duncan, Main, and Clancy and each of their spouses and any other eligible dependents will continue to receive health and welfare benefits at no cost, subject to limitations described in the agreement for a period of 18 months or upon the executive’s death, his spouse and any other eligible dependents will continue to receive health and welfare benefits at no cost, subject to limitations described in the agreement; provided, however, that if the executive dies or is terminated as a result of a long-term disability either within three years before or two years after the occurrence of a change in control of the Company (as defined in the agreement), then, in addition to such continuing health and welfare benefits, the executive or executive’s beneficiary will be paid a lump sum equal to three times the executive’s previous highest annual compensation (as defined in the agreement) (such lump sum payment being referred to herein as the “Lump Sum Payment”), subject to reduction for any prior lump sum payment that may have been paid following the termination for death or long-term disability of the executive.

In addition to the foregoing death benefits payable to Messrs. Duncan, Main and Clancy under their employment agreements, the beneficiaries of each of the named executive officers will also be paid the death benefits provided under the executive’s supplemental life insurance agreement, the amounts of which are included in footnote 3 to the table at page 46 of this Proxy Statement, below.

Under the employment agreements with Messrs. Duncan, Main and Clancy, if the executive chooses to terminate his employment at any time without good reason, including on or after a specified retirement age (62 for Mr. Clancy and 63 for Mr. Main and both have met the specified age), he will be entitled to receive any bonus actually awarded or earned for a prior or current year, but not yet paid as of date of termination and continuing health and welfare benefits for 18 months on the same terms as were available to him as an employee, subject to limitations as described in the agreement, unless the executive chooses to terminate his employment without good reason either within three years before or one year after the occurrence of a change in control, in which case the executive will be paid the Lump Sum Payment.

In addition to the rights provided to Messrs. Duncan and Main under their employment agreements, the salary continuation agreements referenced above also provide additional annual compensation benefits payable to Messrs. Duncan and Main, subject to acceleration upon a change in control (as defined in the agreement), and became payable to the executive for a 20-year period upon his reaching a specified age (68 for Mr. Duncan, which he reached on June 8, 2008, and 63 for Mr. Main, which he reached on April 3, 2010), whether or not the executive retired or remained employed with the Company. The annual amounts payable to each of Messrs. Duncan and Main under their salary continuation agreements are $149,500 and $95,300, respectively.

Under the employment agreements with Messrs. Duncan, Main and Clancy, if the Company (including any successor) terminates the executive at any time for cause, whether before or after the occurrence of a change in control, the executive will be entitled to receive any accrued but unpaid compensation and benefits and will not

be entitled to receive any severance payments or benefits. However, if the Company (including any successor) terminates the executive at any time without cause, whether before or after the occurrence of a change in control, then the executive will be paid the Lump Sum Payment, be reimbursed for professional outplacement service, and will be entitled to receive continuing health benefits for 18 months at no cost to the executive, subject to limitations as described in the agreement.

Under the employment agreements with Messrs. Duncan, Main and Clancy, if the executive chooses to terminate his employment at any time for good reason (as defined in the agreement to include, among several other reasons, a 10% reduction in the executive’s base salary, annual target incentive, or annual equity grant value or material diminution in his authority, duties or responsibilities), whether before or after the occurrence of a change in control, then the executive will be paid the Lump Sum Payment, be reimbursed for professional outplacement service, and will be entitled to receive continuing health benefits for 18 months at no cost to the executive, subject to limitations as described in the agreement.

Each of the employment agreements with Messrs. Duncan, Main and Clancy also provides that the parties may agree to a flexible work arrangement for the remaining term of the agreement. Under the terms of such arrangement, if executive reduces his work schedule below 80% of full-time status, the parties may agree to modify the executive’s position, time and effort, and compensation and the Bank will continue to provide the executive with full benefits, subject to the limitations described in the agreement or equivalent cash compensation considering state and federal income taxes.

Under each of the employment agreements with Messrs. Duncan, Main and Clancy, the executive is subject to confidentiality, non-compete and non-solicitation restrictions for up to one year after the termination of his employment for any reason if the termination occurs before a change in control. The non-compete restrictions do not apply following any termination of the executive’s employment that occurs after a change in control, and any non-compete restrictions that may be in effect at the time of a change in control automatically expire upon such change in control. If the executive breaches any applicable confidentiality, non-compete or non-solicitation covenants, then the Company may enforce a right to recoup prior severance payments made to the executive.

Under the terms of the change in control/noncompetition agreement with Messrs. Irish and Lussier, the executive will be paid a lump sum equal to 1.5 times his previous highest annual compensation (as defined in the agreement to include the sum of the executive’s highest annual base salary and highest annual cash bonus paid within the most recent three years prior to the date of termination), together with certain other specified payments and benefits, including continuation of health and welfare benefits for 18 months on the same terms as were available to the executive as of the date of termination or, if more favorable, as of the date of the change in control, if the executive’s employment is terminated for any reason, whether at the initiative of the Company or of the executive and whether or not for cause, within two years after the date of a change in control of the Company. If Mr. Irish’s or Mr. Lussier's employment is terminated for any reason within one year prior to the occurrence of a change in control, other than for cause, then he is entitled to receive all of the payments and benefits that he would have been entitled to receive if such termination had occurred within two years after the date of such change in control.

Messrs. Irish and Lussier are also subject to confidentiality, non-compete and non-solicitation restrictions for one year following a termination of employment for any reason prior to a change in control (and assuming a change in control does not occur within this one-year period). If Mr. Irish’s or Mr. Lussier's termination in the absence of any change in control is initiated by the Company for any reason other than for cause, then he will be paid a lump sum equal to 75% of the sum of his then-current annual base salary and the amount of any annual incentive or other bonus paid to him with respect to the most recently completed fiscal year prior to the date of termination, subject to recoupment by the Company if he breaches any of the applicable confidentiality, non-compete and non-solicitation covenants.

POTENTIAL PAYMENTS UPON TERMINATION OR CHANGE OF CONTROL

The following table summarizes the estimated payments and benefits to be provided to the named executive officers, as of December 31, 2021, under the various termination scenarios referenced in the table for each of the named executive officers. The estimates shown below factor in base salary and incentive compensation payments, the value realized from accelerated vesting of stock options and restricted stock and other benefits and payments to be paid to the named executive officers under the terms of any agreement or plan that is not generally available to all employees. The following calculations were made without considering any possible “cutback” or other reduction of payments or benefits that could be required under an executive’s employment or other contract:


Name	Change in Control (1)		Voluntary Termination (Includes Normal and Early Retirement) (2)		Involuntary Not for Cause Termination by Company or, if Applicable, Good Reason Termination by Employee		For Cause Termination		Death (2)(3)		Disability
George L. Duncan (4)	$	2,599,601	$	279,584	$	2,079,602	$	258,373	$	2,655,230	$	1,120,385
John P. Clancy, Jr.	$	3,161,844	$	378,063	$	2,658,011	$	352,383	$	2,009,942	$	1,303,076
Richard W. Main (4)	$	1,843,034	$	214,991	$	1,564,463	$	193,780	$	1,526,699	$	756,414
Stephen J. Irish	$	1,026,618	$	—	$	415,345	$	—	$	822,800	$	326,789
Joseph R. Lussier	$	673,398	$	—	$	260,291	$	—	$	606,078	$	209,143

(1)With respect to each of Messrs. Duncan, Clancy, Main, Irish and Lussier the amount shown includes the amount payable, including the estimated expense of continuing benefits, under various termination scenarios either preceding or following a change in control under the executive's employment agreement or, in the case of Messrs. Irish and Lussier, their change in control/noncompetition agreement, which are described in further detail under the heading “Agreements With Named Executive Officers” at pages 42-44 of this Proxy Statement, above.

The amounts shown also include the value attributable to the accelerated vesting of outstanding stock options and unvested restricted stock, which is $517,831 for Mr. Duncan, $501,183 for Mr. Clancy, $276,403 for Mr. Main, $174,718 for Mr. Irish, and $86,639 for Mr. Lussier. The value of any outstanding stock options and unvested restricted stock is based upon the value of the Common Stock on December 31, 2021, which was $44.92 per share, the closing market price of the stock on the NASDAQ Global Market on that date.

(2)With respect to each of Messrs. Duncan, Clancy, Main, Irish and Lussier assumes that termination has not occurred within the time periods before or after a change in control specified in his employment agreement or change in control/noncompetition agreement as applicable.

(3)Includes amounts payable under supplemental life insurance benefits, which equal the following amounts for each of the executives: $1,556,056 for Mr. Duncan; $731,796 for Mr. Clancy; $791,496 for Mr. Main; $496,011 for Mr. Irish and $396,935 for Mr. Lussier.

(4)In addition to the amounts payable to Messrs. Duncan and Main under the various scenarios shown in the table above, each of the executives has a fully vested right to receive annual amounts payable over a 20 year period under the executive’s salary continuation agreement. These annual amounts, payable in monthly installments, are paid to the executive regardless of his employment status, unless the executive is terminated for cause, in which case he would forfeit his right to receive any further payments following the date of termination. In 2021, both Messrs. Duncan and Main were eligible to receive payments under their salary continuation agreements, and each received the full annual amount to which he is entitled, detailed in the table below.

PENSION BENEFITS

The following table sets forth additional information concerning the supplemental retirement benefits as of December 31, 2021:


Name	Plan Name	Number of Years of Credited Service (#)	Present Value of Accumulated Benefit ($) (1)		Payments During Last Fiscal Year ($)
George L. Duncan	Supplemental Employee Retirement Plan	33	$	852,360	$	149,500
Richard W. Main	Supplemental Employee Retirement Plan	33	$	680,888	$	95,300

(1)The present value of accumulated benefit was valued at the established present value of the payments to be received by the executives upon reaching the specified ages noted above at a discount rate of 3.25%. The annual benefit will be payable in twelve monthly installments.

AUDIT COMMITTEE REPORT

The Audit Committee of the Company’s Board of Directors is comprised of seven independent Directors and operates under a written charter. The Audit Committee reviews and reassesses the adequacy of the Audit Committee charter on an annual basis. The Board of Directors has determined that Carol Reid and Nickolas Stavropoulos, who are two of the seven independent Directors, each qualify to serve as an Audit Committee Financial Expert (as such term is defined under applicable SEC rules). The Audit Committee is directly responsible for the appointment, compensation, retention and oversight of the work of the Company’s independent registered public accounting firm, which reports directly to the Audit Committee. The Audit Committee evaluates the Company’s independent registered public accounting firm and the lead audit engagement partner, at a minimum, on an annual basis with consideration given to past performance, the quality of communications with the Audit Committee and management, professional qualifications, expertise and reputation of the firm, and continued independence.

Management is responsible for the Company’s internal controls, the financial reporting process and compliance by the Company with legal and regulatory requirements. The Company’s independent registered public accounting firm is responsible for performing an independent audit of the Company’s consolidated financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States) and for auditing whether the Company maintained, in all material respects, effective internal controls over financial reporting and for issuing reports thereon. The Audit Committee’s responsibility is to monitor and oversee these processes. The Audit Committee’s responsibilities also include resolving any disagreements that may arise between management and the Company's independent registered public accounting firm. In addition, the Audit Committee is responsible for the oversight of financial reporting, oversight of the Company’s Internal Audit function, oversight of management’s efforts to manage third party risk, the oversight of compliance by the Company with legal and regulatory requirements, and oversight of procedures established for the receipt, retention and treatment of any complaints that may be received by the Company regarding accounting, internal controls or auditing matters and the confidential, anonymous submission by employees of the Company of any concerns that may arise regarding questionable accounting or auditing matters.

The Audit Committee has met and held discussions with management and the Company’s independent registered public accounting firm. Management has represented to the Audit Committee that the Company’s consolidated financial statements were prepared in accordance with U.S. generally accepted accounting principles, and the Audit Committee has reviewed and discussed the consolidated financial statements with management and the Company’s independent registered public accounting firm. The Audit Committee has discussed with the Company’s independent registered public accounting firm the matters required to be discussed under the professional standards of the AICPA and Public Company Accounting Oversight Board.

The Company’s independent registered public accounting firm has also provided to the Audit Committee the written disclosures and the letter required by applicable requirements of the Public Company Accounting Oversight Board regarding the independent accountant’s communications with the Audit Committee concerning independence, and the Audit Committee has discussed with the Company’s independent registered public accounting firm that firm’s independence.

Based upon the Audit Committee’s discussions with management and the Company’s independent registered public accounting firm, and the Audit Committee’s review of the representation of management and the reports of the Company’s independent registered public accounting firm to the Audit Committee, the Audit Committee recommended that the Board of Directors include the audited consolidated financial statements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021 as filed with the SEC on March 10, 2022.

The Audit Committee and the Board of Directors have also recommended, subject to shareholder ratification, the selection of RSM US LLP, as the Company’s independent registered public accounting firm for the year ending December 31, 2021.

From time to time, certain Directors and executive officers of the Company who are customers of the Bank have entered into loan, wealth management and brokerage and deposit transactions with the Bank 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. Such loan transactions with Directors and executive officers of the Bank and with such corporations, non-profit entities and partnerships 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. Charitable contributions have been made in the normal course of business to certain non-profit organizations where Directors serve as officers or directors of these organizations.

The Audit Committee reviews disclosures made in this Proxy Statement and all other reports and filings of the Company required under the federal securities laws regarding all related-party transactions that are required to be disclosed under the requirements of Item 404 of the SEC’s Regulation S-K. Any transactions involving the Company (including any subsidiaries) and related parties must be conducted on an arm’s-length basis and any consideration paid or received by the Company in connection with any such transaction shall be on terms no less favorable to the Company than terms that would be available under the same or similar circumstances with an unaffiliated third party.

All related party transactions are also disclosed to the Audit Committee. The Executive Chairman, Chief Executive Officer and President may approve small dollar related party transactions.
