NOTICE OF ANNUAL MEETING OF STOCKHOLDERS

TO BE HELD MAY 15, 2025

In accordance with rules and regulations adopted by the Securities and Exchange Commission, we have elected to furnish our proxy materials to stockholders by providing access to the materials on the Internet. Accordingly, a Notice of Internet Availability of Proxy Materials (the Internet Availability Notice) has been mailed to the majority of our stockholders, while other stockholders have instead received paper copies of the documents accessible on the Internet. It is important that your shares be represented and voted whether or not you plan to attend the annual meeting. If you are the registered holder of your shares and are viewing the proxy statement on the Internet, you may grant your proxy electronically via the Internet by following the instructions on the Internet Availability Notice previously mailed to you and the instructions listed on the Internet site. If you are receiving a paper copy of the proxy statement, you may vote by completing and mailing the proxy card enclosed with the proxy statement, or you may grant your proxy electronically via the Internet or by telephone by following the instructions on the proxy card. If your shares are held in “street name,” which means your shares are held of record by a broker, bank or other nominee, you should review the Notice of Internet Availability of Proxy Materials used by that firm to

determine whether and how you will be able to submit your proxy by telephone or over the Internet. Submitting a proxy over the Internet, by telephone or by mailing a proxy card will ensure your shares are represented at the annual meeting. A list of stockholders entitled to vote at the annual meeting will be available for examination by stockholders of record at www.virtualshareholderemeeting.com/BIGC2025 during the annual meeting.

PROXY STATEMENT SUMMARY

This proxy statement (the “Proxy Statement”) is furnished in connection with the solicitation of proxies by the Board of Directors (the “Board of Directors” or the “Board”) of BigCommerce Holdings, Inc., a Delaware corporation, for use at the Annual Meeting of Stockholders. This Proxy Statement and related materials are first being mailed to stockholders on or about April 2, 2025. References in this Proxy Statement to “we,” “us,” “our,” or the “Company” refer to BigCommerce Holdings, Inc. and its consolidated subsidiaries, and references to the “Annual Meeting” are to the 2025 annual meeting of stockholders. When we refer to the Company’s fiscal year, we mean the annual period ended on December 31, 2024. This Proxy Statement covers our 2024 fiscal year, which was from January 1, 2024 through December 31, 2024, or fiscal 2024. Certain information contained in this Proxy Statement is incorporated by reference into Part III of our Annual Report on Form 10-K for the fiscal year ended December 31, 2024, as filed by the Company with the U.S. Securities and Exchange Commission, or SEC, on February 27, 2025.

This summary highlights information contained elsewhere in this Proxy Statement and does not contain all of the information that you should consider. You should read the entire Proxy Statement carefully before voting.

Our Annual Meeting

At the Annual Meeting, the stockholders of the Company will be asked to vote on the three proposals below. Your vote is very important. Accordingly, whether or not you plan to attend the Annual Meeting, you should vote by using one of the methods described in these proxy materials. You may vote your shares at the Annual Meeting by voting via the Internet or by telephone as described in these proxy materials or by having your shares represented at the Annual Meeting by a valid proxy. If your shares are not registered directly in your name (e.g., you hold your shares in a stock brokerage account or through a bank or other holder of record), you may vote by following the instructions detailed on the notice or voting instruction form you receive from your broker or other nominee. A list of all stockholders entitled to vote at the Annual Meeting will be available for inspection at our executive offices ten days prior to the Annual Meeting.

Any stockholder who executes and delivers a proxy has the right to revoke it at any time before it is exercised by delivering to the Secretary of the Company an instrument revoking it or a duly executed proxy bearing a later date, or by attending the Annual Meeting and voting. Subject to revocation, the proxy holders will vote all shares represented by a properly executed proxy received in time for the Annual Meeting in accordance with the

instructions on the proxy. If no instruction is specified with respect to a matter to be acted upon, the shares represented by the proxy will be voted in accordance with the recommendation of the Board of Directors.

The expenses of preparing, assembling, printing and mailing the Internet Availability Notice, this Proxy Statement and the materials used in the solicitation of proxies will be borne by the Company. Proxies will be solicited through the Internet and the mail and may be solicited by our officers, directors and employees in person or by telephone, email or facsimile. They will not receive additional compensation for this effort. We do not anticipate paying any compensation to any other party for the solicitation of proxies, but may reimburse brokerage firms and others for their reasonable expenses in forwarding solicitation material to beneficial owners. The Company may retain the services of a proxy solicitation firm if, in the Board’s view, it is deemed necessary or advisable. Although the Company does not currently expect to retain such a firm, it estimates that the fees of such a firm could be up to $20,000, plus out-of-pocket expenses, all of which would be paid by the Company.

Quorum Requirements

In order to constitute a quorum for the conduct of business at the Annual Meeting, a majority of the shares of the Common Stock entitled to vote at the Annual Meeting must be present at the meeting or represented by proxy. Shares represented by proxies that reflect abstentions or broker non-votes will be counted as shares that are present and entitled to vote for purposes of determining the presence of a quorum.

Required Vote

Each share of our Common Stock outstanding on the record date is entitled to one vote on each of the two director nominees. Each share of our Common Stock outstanding on the record date is entitled to one vote on each other matter. For the election of directors, the nominees to serve as directors will be elected by a plurality of the votes cast by the stockholders entitled to vote at the election. You may vote “For All,” “Withhold All,” or “For All Except,” with respect to the director nominees. Votes that are withheld will be excluded entirely from the vote with respect to the nominee from which they are withheld and will have no effect on the election of directors. With respect to Proposals 2 and 3, approval of each proposal requires the affirmative vote of a majority in voting power of the shares in attendance at the meeting or represented by proxy and entitled to vote on the matter. Abstentions will have the same effect as a vote against each of Proposals 2 and 3.

For Proposal 3, the advisory vote to approve the compensation of our named executive officers (say-on-pay vote), because your vote is advisory, it will not be binding on the Company, our Board or our compensation committee. However, the Board and the compensation committee will consider the outcome of the vote when making future executive compensation decisions to the extent appropriate.

Broker non-votes occur when a beneficial owner of shares held in “street name” does not give instructions to the broker, bank or other nominee holding the shares as to how to vote on matters deemed “non-routine” by stock exchange rules and regulations. Proposal 2 regarding ratification of the appointment of our independent auditors is a routine matter. If your shares are held in an account at a bank or brokerage firm, that bank or brokerage firm may vote your shares of Common Stock on Proposal 2. Accordingly, we do not expect there to be any broker non-votes for Proposal 2. However, if your shares are held in an account at a bank or brokerage firm, that bank or brokerage will not be permitted to vote your shares of Common Stock with respect to Proposal 1 or Proposal 3, unless you provide instructions as to how your shares should be voted. Accordingly, we encourage you to vote promptly, even if you plan to attend the virtual Annual Meeting. In tabulating the voting results for any particular proposal, shares that constitute broker non-votes are not considered entitled to vote on that proposal. Broker non-votes, if any, will have no effect on the outcome of either Proposal 1 or Proposal 3.

Additional Information Regarding the Internet Availability of Our Proxy Materials

We are pleased to take advantage of SEC rules that allow companies to furnish their proxy materials over the Internet. Accordingly, we sent to the majority of our stockholders an Internet Availability Notice regarding the Internet availability of the proxy materials for this year’s annual meeting. Other stockholders were instead sent paper copies of the proxy materials accessible on the Internet. Instructions on how to access the proxy materials over the Internet or to request a paper copy can be found in the Internet Availability Notice. In addition, stockholders may request to receive proxy materials in printed form by mail or electronically by email on an ongoing basis by going to www.proxyvote.com and following the instructions or calling 1-800-579-1639. A stockholder’s election to receive proxy materials by mail or e-mail will remain in effect until the stockholder terminates or changes such election.

Please note that you cannot vote your shares by filling out and returning the Internet Availability Notice. The Internet Availability Notice does, however, include instructions on how to vote your shares.

If your shares are registered directly in your name with our transfer agent, you are considered, with respect to those shares, the “stockholder of record.” In that case, either the Internet Availability Notice or the Notice of Annual Meeting, this Proxy Statement and our Annual Report on Form 10-K for the fiscal year ended December 31, 2024 have each been sent directly to you.

If your shares are held in a stock brokerage account or by a bank or other holder of record, you are considered the “beneficial owner” of shares held in street name. In such case, either a notice similar to the Internet Availability Notice or the Notice of Annual Meeting, this Proxy Statement and our Annual Report on Form 10-K for the fiscal year ended December 31, 2024 should have been provided (or otherwise made available) to you by your broker, bank or other holder of record who is considered, with respect to those shares, the stockholder of record. As the beneficial owner, you have the right to direct your broker, bank or other holder of record on how to vote your shares by following their instructions for voting.

PROPOSAL 1: ELECTION OF TWO DIRECTORS

General

Our Seventh Amended and Restated Certificate of Incorporation (our “Certificate of Incorporation”) provides for a classified Board of Directors consisting of three classes of directors, with each class serving staggered three-year terms and a nearly equal number of board members in each class, as determined by our Board. As a result, a portion of our Board of Directors will be elected each year. Our Board of Directors has nominated Ms. Sally Gilligan and Mr. Satish Malhotra as Class II directors with a term that would expire at the 2028 annual meeting of stockholders. Messrs. Travis Hess, Lawrence Bohm and Jeff Richards have been designated Class I directors, and their term expires at the 2027 annual meeting of stockholders. Mr. Donald E. Clarke and Ms. Ellen F. Siminoff have been designated Class III directors, and their term expires at the 2026 annual meeting of stockholders.

On the recommendation of the nominating and corporate governance committee of our Board of Directors, our Board of Directors, including its independent directors, selected and approved Ms. Sally Gilligan and Mr. Satish Malhotra as nominees for election as Class II directors, the class being elected at the Annual Meeting, each to serve for a term of three years, expiring at the 2028 annual meeting of the stockholders or until his or her successor is duly appointed or elected and qualified or until his or her earlier death, resignation or removal. We are not aware of any arrangements or understandings between the director nominees and any other person pursuant to which such persons were selected as a director nominee.

Ms. Sally Gilligan and Mr. Satish Malhotra currently serve as members of our Board of Directors and have agreed to serve if elected. In the event the nominees named herein are unable to serve or decline to serve at the time of the Annual Meeting, the persons named in the enclosed proxy will exercise discretionary authority to vote for substitutes. Unless otherwise instructed, the proxy holders will vote the proxies received by them FOR the nominees. The proxy cannot be voted for a greater number of persons than the number of nominees named.

Recommendation of the Board of Directors

Our Board of Directors unanimously recommends that the stockholders vote FOR the election of the Class II director nominees, Ms. Sally Gilligan and Mr. Satish Malhotra. Unless otherwise instructed, the proxy holders will vote the proxies received by them FOR the election of all the Class II director nominees.

Directors and Nominees

The following table and biographical information sets forth certain information about Ms. Sally Gilligan and Mr. Satish Malhotra as well as the continuing directors. Such information is current as of April 2, 2025. The information presented below for each director includes the specific experience, qualifications, attributes and skills that led us to the conclusion that these directors should be nominated to serve on our Board of Directors in light of our business. There is no family relationship between any of our executive officers, directors, or director nominees.

Nominees for Election to the Board of Directors (Class II Directors)

Sally Gilligan has been a member of our Board of Directors since July 2022.

CORPORATE GOVERNANCE

We are committed to continually enhancing our strong corporate governance practices, which we believe helps us sustain our success and build long-term value for our stockholders. Our Board of Directors sets high standards for our employees, officers and directors. Implicit in this philosophy is the importance of sound corporate governance. It is the duty of the Board of Directors to serve as a prudent fiduciary for shareholders and to oversee the management of the Company’s business. Our governance structure enables independent, experienced and accomplished directors to provide advice, insight, guidance and oversight to advance the interests of the Company and our stockholders.

Affirmative Determinations Regarding Director and Nominee Independence

Under the rules of Nasdaq, independent directors must comprise a majority of a listed company’s Board of Directors. In addition, the rules of Nasdaq require that, subject to specified exceptions, each member of a listed company’s audit, compensation, and nominating and corporate governance committee be independent. Audit committee members must also satisfy the independence criteria set forth in Rule 10A-3 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Under the rules of Nasdaq, a director will only qualify as an “independent director” if, in the opinion of that company’s Board of Directors, that person does not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director.

Based upon information requested from and provided by each director concerning his or her background, employment, and affiliations, including family relationships, our Board of Directors has determined that each of Lawrence Bohn, Donald E. Clarke, Sally Gilligan, Satish Malhotra, and Jeff Richards, representing five of our seven directors, do not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director and is “independent” as that term is defined under the rules of Nasdaq. In making this determination, our Board of Directors considered the relationships that each non-employee director has with us and all other facts and circumstances our Board of Directors deemed relevant in determining independence, including the beneficial ownership of our Common Stock by each non-employee director and the relationship of certain non-employee directors with certain of our significant stockholders.

Each member of our Board of Directors serving on our audit, compensation and nominating and corporate governance committees is “independent” within the meaning of the applicable rules of Nasdaq and, as applicable, the Exchange Act.

Background and Experience of Directors

Our nominating and corporate governance committee is responsible for reviewing with our Board of Directors, on an annual basis, the appropriate characteristics, skills and experience required for the Board of Directors as a whole and its individual members. In evaluating the suitability of individual candidates (both new candidates and current members), the nominating and corporate governance committee, in recommending candidates for election, and the Board of Directors, in approving (and, in the case of vacancies, appointing) such candidates, will take into account many factors, including the following:

Role of the Board in Risk Oversight

Our Board of Directors has an active role, as a whole and also at the committee level, in overseeing the management of our risks. Our Board of Directors is responsible for general oversight of risks and regular review of information regarding our risks, including credit risks, liquidity risks, and operational risks. The compensation committee is responsible for overseeing the management of risks relating to our executive compensation plans and arrangements as well as our policies, procedures and practices with respect to human capital management and talent development. The audit committee is responsible for overseeing the management of risks relating to accounting matters, financial reporting, and privacy and cybersecurity. The nominating and corporate governance committee is responsible for overseeing the management of risks associated with the independence of our Board of Directors and potential conflicts of interest. Although each committee is responsible for evaluating certain risks and overseeing the management of such risks, the entire Board of Directors is regularly informed about such risks through discussions from committee members. We believe that our Board’s leadership structure supports effective risk management because it allows independent directors at the board level and on our committees to exercise oversight over management.

Our Board of Directors and audit committee jointly oversee our security organization, which is charged with assessing and taking steps to mitigate the data privacy and cybersecurity risks that we face as a software-as-a-service platform, and recognize that data protection forms an important part of our risk management. The Board of Directors receives regular updates, not less than annually, from senior management and also receives periodic updates from the Company’s subject matter experts in these areas to assess these risks. The Company takes a risk-based approach to security, and we maintain a cybersecurity risk management program that is designed and assessed based on various standards, including our annual ISO 27001 Certification. This does not imply that we meet any particular technical standards, specifications, or requirements of any particular framework, only that we use these standards as a guide to help us identify, assess, and manage cybersecurity risks relevant to our business. Our security organization periodically evaluates our product offerings, agreements, policies, investments, training, and staffing levels to identify opportunities to enhance privacy compliance and cybersecurity and provides briefings to the Board of Directors and audit committee on these matters as deemed necessary.

Board Leadership Structure

The Board of Directors does not have a policy regarding the separation of the roles of Chief Executive Officer and Chairman of the Board of Directors, as the Board of Directors believes it is in the best interests of the Company to make that determination based on the position and direction of the Company and the membership of the Board of Directors.

In October, the Board appointed Ellen F. Siminoff as Executive Chair, a newly-created role. The Executive Chair will provide leadership and direction to the Board, and work with the Company’s Chief Executive Officer and other members of the Company’s executive team to provide, among other things, strategic expertise with respect to the Company’s strategy for future growth. This structure allows for a clear separation of duties, with the Executive Chair focusing on Board governance and long-term strategic vision, while the CEO leads day-to-day operations.

Lead Independent Director

As part of our continued efforts to ensure a strong, independent and active Board of Directors, we have designated a Lead Independent Director, who serves as the principal liaison between independent directors and the Chairperson and senior management, as well as the lead approver of all agendas, meetings and related information. We believe this role is integral to providing effective oversight of management and strong leadership of the independent directors. Mr. Richards currently serves as our Lead Independent Director.

Attendance at Meetings

During the year ended December 31, 2024, our Board of Directors met 14 times. Each member of the Board of Directors attended at least 75 percent of the meetings of our Board of Directors and the meetings of any of our board committees on which each member of the Board of Directors served that were held during the term of each such director. Our Board of Directors and each of the board committees also acted by way of various unanimous written consents during the year ended December 31, 2024. In addition, the Board of Directors and each board committee met, at times, without management present in executive session.

Although we do not have a formal policy regarding attendance by members of our Board of Directors at our Annual Meeting of Stockholders, we encourage our directors to attend. In 2024, all members of our Board of Directors attended our annual meeting of stockholders.

Board Committees

Our Board of Directors has established an audit committee, a compensation committee, and a nominating and corporate governance committee. The composition and responsibilities of each committee are described below. Our Board of Directors may also establish from time to time any other committees that it deems necessary or desirable. Members serve on these committees until their resignation or until otherwise determined by our Board of Directors.

The current composition of each board committee is set forth below.

Audit committee

Our audit committee consists of Donald E. Clarke, Sally Gilligan, and Jeff Richards, each of whom our Board of Directors has determined satisfies the independence requirements for audit committee members under the listing standards of Nasdaq and Rule 10A-3 under the Exchange Act. Each member of our audit committee meets the financial literacy requirements under the rules and regulations of Nasdaq and the SEC. The chair of our audit committee is Mr. Clarke, who our Board of Directors has determined is an “audit committee financial expert” as defined by Item 407(d) of Regulation S-K. Our audit committee held five meetings in 2024.

Our audit committee is responsible for, among other things:

Our audit committee operates under a written charter that satisfies the applicable listing standards of Nasdaq and is available on the investor relations section of our website at www.bigcommerce.com.

Compensation committee

Our compensation committee consists of Satish Malhotra, Donald E. Clarke, and Lawrence Bohn, with Mr.Malhotra serving as chair. Our Board of Directors has determined that each of the compensation committee members is a non-employee member of our Board of Directors as defined in Rule 16b-3 under the Exchange Act and an outside director as that term is defined in Section 162(m) of the Code. The composition of our compensation committee meets the requirements for independence under the current listing standards of Nasdaq and current SEC rules and regulations. Decisions regarding the compensation of our executive officers have historically been made by the compensation committee. Our compensation committee held four meetings in 2024.

The compensation committee is responsible for, among other things:

Our compensation committee operates under a written charter that satisfies the applicable listing standards of Nasdaq and is available on the investor relations section of our website at www.bigcommerce.com.

Nominating and corporate governance committee

Our nominating and corporate governance committee consists of Sally Gilligan, Jeff Richards, and Lawrence Bohn, with Mr. Richards serving as chair. The composition of our nominating and governance committee meets the requirements for independence under the current listing standards of Nasdaq and current SEC rules and regulations. Our nominating and corporate governance committee held three meetings in 2024.

The nominating and corporate governance committee is responsible for, among other things:

Our nominating and corporate governance committee operates under a written charter that satisfies the applicable listing standards of Nasdaq and is available on the investor relations section of our website at www.bigcommerce.com.

Compensation committee interlocks and insider participation

No member of our compensation committee is or has been a former or current executive officer or employee of the Company. During 2024, no member of our compensation committee had a relationship that must be described under the SEC rules relating to disclosure of related person transactions. None of our executive officers currently serves, or has served during the last completed fiscal year, as a member of the Board of Directors or compensation committee (or other committee performing equivalent functions) of any entity that has one or more executive officers serving on our Board of Directors or compensation committee.

The Company’s Director Nomination Process

As indicated above, our nominating and corporate governance committee oversees the director nomination process. This committee is responsible for assisting the Board of Directors in establishing minimum qualifications for director nominees, including qualities and skills that members of our Board of Directors are expected to possess. Under our nominating and corporate governance committee charter, these criteria include the following:

Our nominating and corporate governance committee identifies and evaluates individuals qualified to become members of our Board of Directors. Our nominating and corporate governance committee then recommends that our Board of Directors select the director nominees for the election at the next annual meeting of stockholders, or to fill vacancies on our Board of Directors occurring between annual meetings of the stockholders.

We believe it is important to have an appropriate mix of experience for the optimal functionality of the Board of Directors. Our nominating and corporate governance committee charter requires that the committee consider each candidate’s qualities and skills and our nominating and corporate governance committee considers each candidate’s background, ability, judgment, skills and experience in the context of the needs and current make-up of the Board of Directors when evaluating director nominees. The Board of Directors believes it is important for each member of the Board of Directors to possess skills and knowledge in the areas of leadership of large, complex organizations; finance; strategic planning; laws and regulations; government relations; and relevant industries, especially the ecommerce space. These considerations help ensure that the Board of Directors as a whole has the appropriate mix of characteristics, skills and experiences for the optimal functioning of the Board of Directors in its oversight of our Company. As part of its periodic self-assessment process, the nominating and corporate governance committee reviews and evaluates its performance, including overall composition of the Board of Directors and the criteria that it uses for selecting nominees in light of the specific skills and characteristics necessary for the optimal functioning of the Board of Directors in its oversight of our Company. The nominating and corporate governance committee considers all of the criteria described above in identifying and selecting nominees and in the future may establish additional minimum criteria for nominees.

The nominating and corporate governance committee will consider nominees for the Board of Directors who are recommended by stockholders who meet the eligibility requirements for submitting stockholder proposals for inclusion in the Company’s next proxy statement. If an eligible stockholder wishes to recommend a nominee, he or she should submit such recommendation in writing to the Chair, nominating and corporate governance committee, c/o Secretary of the Company, BigCommerce Holdings, Inc., 11305 Four Points Drive, Building II, Suite 100, Austin, Texas 78726, by the deadline for stockholder proposals set forth in the Company’s last proxy statement, specifying the information required by the nominating and corporate governance committee charter. Any recommendations should include whatever supporting material the stockholder considers appropriate in support of that recommendation and must include the information that would be required to be disclosed under the SEC’s rules in a proxy statement soliciting proxies for the election of such candidate and a signed consent of the candidate to serve as our director, if elected. All such recommendations will be brought to the attention of the nominating and corporate governance committee, and the nominating and corporate governance committee shall evaluate such director nominees in accordance with the same criteria applicable to the evaluation of all director nominees.

Shareholder Engagement

Our Commitment to Shareholder Engagement

Shareholder feedback is vital to our Board. We engage with shareholders year-round, both proactively and in response to their specific concerns.

Our Approach

Management and directors engage with our stockholders throughout the year in a variety of forums. Our interactions cover a broad range of governance and business topics, including proxy access, board elections, compensation practices, and business strategy. Our engagement activities and meaningful exchanges to which we

have been exposed provide us with a valuable understanding of our shareholders’ perspectives and an opportunity to share views with them. We look forward to maintaining an open line of dialogue with our shareholders.

Responsiveness to Investors and Shareholders

The Company initiates engagement with shareholders who have expressed interest and shareholders we believe may have unique suggestions or insights that may be relevant to our business, operations or industry. In the past year, the Company sought feedback from shareholders representing approximately 51% of outstanding Common Stock. Subsequently, we engaged directly with shareholders representing 21% of outstanding Common Stock on matters related to executive compensation, pay versus performance, corporate governance, and strategic matters. The feedback from those discussions provided a framework for certain disclosures in this Proxy Statement.

Additionally, the Company acknowledges the importance of shareholder engagement, particularly in response to feedback on our executive compensation programs. We recognize that lower voting support levels for executive compensation matters can serve as an important signal from shareholders. As such, our outreach efforts reflect our commitment to good governance, transparency, and accountability in addressing shareholder concerns.

We encourage you to visit the Corporate Governance area of the “Investor Relations” section of our website (https://investors.bigcommerce.com/corporate-governance/governance-overview) where you will find detailed information about our corporate governance practices and policies, including our nominating and corporate governance committee charter.

Stockholders who would like to send communications to our Board of Directors, any board committee or to any individual director may do so by submitting such communications to the Secretary of the Company, c/o BigCommerce Holdings, Inc., 11305 Four Points Drive, Building II, Suite 100, Austin, Texas 78726. We suggest, but do not require, that such submissions include the name and contact information of the stockholder making the submission and a description of the matter that is the subject of the communication. The Secretary will then distribute such information to our Board of Directors for review. Communications received by the Company may be reviewed by the Secretary to ensure appropriate and careful review of the matter.

Code of Ethics and Conduct

We have adopted a code of ethics and conduct that applies to all employees, including employees of our subsidiaries, as well as each member of our Board of Directors.

PROPOSAL 2: RATIFICATION OF APPOINTMENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The audit committee is directly responsible for the appointment, compensation, retention and oversight of the independent external audit firm retained to audit the Company’s financial statements. Our audit committee has selected Ernst & Young LLP, or Ernst & Young, to serve as our independent registered public accounting firm to audit the consolidated financial statements of BigCommerce Holdings, Inc. for the fiscal year ending December 31, 2025. As a matter of good corporate governance, we are asking the stockholders to ratify the selection of Ernst & Young LLP as our independent registered public accounting firm for the year ending December 31, 2025. The affirmative vote of a majority of the Common Stock having voting power present in person or represented by proxy and entitled to vote will be required to ratify the selection of Ernst & Young LLP.

Stockholders are not required to ratify the appointment of Ernst & Young LLP as our independent registered public accounting firm. If stockholders fail to ratify the appointment, the audit committee will consider whether or not to retain Ernst & Young LLP. Even if the appointment is ratified, the audit committee may direct the appointment of a different independent registered public accounting firm at any time during the year if it determines that such a change would be in the best interests of the Company and our stockholders.

Ernst & Young LLP has served as our auditor since 2012. A representative of Ernst & Young LLP is expected to be present virtually at the Annual Meeting to respond to appropriate questions and make a statement if he or she so desires.

Principal Accountant Fees and Services

The following table sets forth the aggregate fees billed by Ernst & Young LLP for the fiscal years ended December 31, 2024 and December 31, 2023.

Pre-Approval Policies

Our audit committee pre-approved all audit, audit-related, tax and other fees for services performed by our independent registered public accounting firm during 2024. The audit committee has adopted an Audit and Non-Audit Services Pre-Approval Policy (the “Audit Pre-Approval Policy”). The Audit Pre-Approval Policy provides for general pre-approval for a specified range of fees for certain categories of routine services to be provided during a given calendar year. This general pre-approval is automatically renewed at the beginning of each calendar year, unless otherwise determined by the audit committee. If the cost of any proposed service exceeds the amount for which general pre-approval has been established, specific pre-approval by the audit committee is required. Specific pre-approval of services is considered at the regular meetings of the audit committee. The Audit Pre-Approval Policy also establishes a list of prohibited non-audit services. In making all of its pre-approval determinations, the audit committee considers, among other things, whether such services are consistent with the rules promulgated by the

Public Company Accounting Oversight Board (the “PCAOB”) and the SEC regarding auditor independence, whether the independent auditor is best positioned to provide the most effective and efficient service, and whether the service might enhance the Company’s ability to manage and control risk or improve audit quality. These and other factors are considered as a whole and no one factor is necessarily determinative.

Recommendation of the Board of Directors

Our Board of Directors unanimously recommends that the stockholders vote FOR the ratification of Ernst & Young LLP as the Company’s independent registered public accounting firm for the year ending December 31, 2025.

AUDIT COMMITTEE REPORT

Our audit committee currently consists of three directors. Messrs. Clarke and Richards and Ms. Gilligan are each, in the judgment of the Board of Directors, an independent director. The audit committee acts pursuant to a written charter that has been adopted by the Board of Directors. A copy of the charter is available on the investor relations section of our website.

The audit committee oversees our financial reporting process on behalf of the Board of Directors. The audit committee is responsible for retaining our independent registered public accounting firm, evaluating its independence, qualifications and performance, and approving in advance the engagement of the independent registered public accounting firm for all audit and non-audit services. The audit committee’s specific responsibilities are set forth in its charter. The audit committee reviews its charter at least annually.

Management has the primary responsibility for the financial statements and the financial reporting process, including internal control systems, and procedures designed to ensure compliance with applicable laws and regulations. Our independent registered public accounting firm, Ernst & Young LLP, is responsible for expressing an opinion as to the conformity of our audited financial statements with generally accepted accounting principles.

The audit committee has reviewed and discussed with management the Company’s audited financial statements. The audit committee has also discussed with Ernst & Young LLP all matters that the independent registered public accounting firm was required to communicate and discuss with the audit committee, including the applicable requirements of the Public Company Accounting Oversight Board (PCAOB) and the SEC. In addition, the audit committee has met with the independent registered public accounting firm, with and without management present, to discuss the overall scope of the independent registered public accounting firm’s audit, the results of its examinations, its evaluations of the Company’s internal controls and the overall quality of our financial reporting.

The audit committee has received the written disclosures and the letter from the independent registered public accounting firm required by applicable requirements of the PCAOB regarding the independent registered public accounting firm’s communications with the audit committee concerning independence and has discussed with the independent registered public accounting firm its independence.

Based on the review and discussions referred to above, the audit committee recommended to our Board of Directors that the company’s audited financial statements be included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2024.

PROPOSAL 3: NON-BINDING, ADVISORY VOTE TO APPROVE THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS (SAY-ON-PAY VOTE)

In accordance with the requirements of Section 14A of the Exchange Act, we are asking our stockholders to consider and vote upon the resolution below to approve, on a non-binding, advisory basis, the compensation of our named executive officers (also referred to as NEOs) as disclosed in this Proxy Statement. This proposal, commonly known as a “say-on-pay” proposal, gives our stockholders the opportunity to express their views on our NEOs’ compensation. The Say-on-Pay Vote is not intended to address any specific item of compensation, but rather the overall compensation of our NEOs and the philosophy, policies and practices described in this Proxy Statement.

As described in detail in the “Compensation Discussion and Analysis” section of this Proxy Statement the key objectives of our executive compensation program are to attract, motivate, and reward leaders who create an inclusive and diverse environment and have the skills and experience necessary to successfully execute our strategic plan to maximize stockholder value by aligning executive compensation with Company performance and stockholder value creation.

Our executive compensation program is designed to:

Stockholders are encouraged to read the “Compensation Discussion and Analysis,” the accompanying compensation tables, and the related narrative disclosure contained in this Proxy Statement for a full description of our executive compensation programs.

This vote is advisory only and non-binding. However, the Board and the compensation committee will consider the outcome of this vote when making future executive compensation decisions to the extent appropriate. We currently ask our stockholders to approve, on a non-binding, advisory basis, the compensation of our NEOs on an annual basis, and we expect to hold the next such vote at our 2026 annual meeting of stockholders.

We believe that the compensation committee has developed a compensation program for our NEOs that motivates outstanding performance and rewards behavior that aligns management’s interest with those of stockholders. Accordingly, we ask our stockholders to vote “FOR” the following resolution at the Annual Meeting:

“NOW, THEREFORE, BE IT RESOLVED, that the stockholders of the Company approve, on a non-binding, advisory basis, the 2024 compensation of the Company’s named executive officers, as disclosed in the Compensation Discussion and Analysis, compensation tables and related narrative discussion of this Proxy Statement.”

COMPENSATION DISCUSSION AND ANALYSIS

General

In this Compensation Discussion and Analysis (“CD&A”), we provide an overview and analysis of the compensation awarded to or earned by our named executive officers identified below (each, an “NEO”) during fiscal 2024, including the elements of our compensation program for NEOs, material compensation decisions made under that program for fiscal 2024, and the material factors considered in making those decisions. Our NEOs for the year ended December 31, 2024 are:

Executive Summary

2024 Performance Highlights and Pay for Performance.

Our executive compensation programs are designed to deliver pay in accordance with corporate and individual performance, reward superior performance and provide consequences for underperformance. We believe that the compensation of our NEOs for fiscal year 2024 was aligned with the Company’s performance during 2024. Highlights of that performance include:

In order to align pay with performance, a significant portion of our NEOs’ compensation is delivered in the form of equity awards and annual cash incentives, each of which depends on our actual performance.

For fiscal year 2024, approximately 65% of our NEOs’ total target compensation was in the form of stock options and restricted stock units (“RSUs”), which will vest based on continued service, and performance-based RSUs, which will vest based on achievement of Company adjusted EBITDA, revenue and total stockholder return (“TSR”) metrics.

2024 Compensation Highlights. Consistent with our compensation philosophy, key compensation decisions for 2024 included the following:

Compensation Governance and Best Practices. We are committed to having strong governance standards with respect to our compensation programs, procedures and practices. Our key compensation practices include the following:

Executive Compensation Objectives and Philosophy

The key objective in our executive compensation program is to attract, motivate, and reward leaders who create an inclusive and diverse environment and have the skills and experience necessary to successfully execute our strategic plan to maximize stockholder value. Our executive compensation program is designed to:

We strive to set our overall total compensation at a competitive level. Executives may be compensated above or below the targeted market position based on factors such as experience, performance, scope of position, and the competitive demand for proven executive talent, as described further below under “—Determination of Executive Compensation.”

Determination of Executive Compensation

Role of Compensation Committee and Executive Officers

The compensation committee is responsible for establishing and overseeing our executive compensation programs and annually reviews and determines the compensation to be provided to our NEOs.

In setting executive compensation, the compensation committee considers a number of factors, including the recommendations of our Chief Executive Officer (other than with respect to the Chief Executive Officer’s own compensation), the Executive Chair of the Board of Directors, and our human resources team, current and past total compensation, competitive market data and analysis provided by the compensation committee’s independent compensation consultant, Company performance and each executive’s impact on performance, each executive’s relative scope of responsibility and potential, each executive’s individual performance and demonstrated leadership, and internal equity pay considerations. Our Chief Executive Officer uses the benchmark peer data provided by the compensation committee’s compensation consultant to determine the size of equity-based awards, and adjusts each NEO’s equity grant value (other than his own) upwards or downwards from such peer data after considering the NEO’s role criticality and individual performance. Our Board makes decisions regarding our Chief Executive Officer’s compensation, following recommendation from the compensation committee.

Role of Compensation Consultant

The compensation committee has retained Aon-Radford (“Aon”) as an independent compensation consultant to provide executive compensation advisory services, help evaluate our compensation philosophy and objectives, design a competitive executive compensation program that will continue to attract top executive talent and reflect our compensation philosophy, and provide guidance in administering our executive compensation program.

In addition, Aon’s affiliates (Aon plc and its related entities) performed insurance advisory and insurance brokerage services for us during 2024, for which we paid approximately $264,000. Insurance premiums and related fees were paid to Aon plc and passed through to third-party insurance companies not affiliated with Aon plc. Our compensation committee reviewed these services and fees and considered the independence of Aon in light of SEC rules regarding conflicts of interest involving compensation consultants and applicable Nasdaq listing standards

regarding compensation consultant independence. Based on its review, our compensation committee determined that Aon was independent, and that Aon’s services did not raise any conflicts of interest.

In consultation with Aon, in August 2023, our compensation committee selected our peer group for 2024 compensation as follows, focusing primarily on domestic, publicly-traded SaaS and e-commerce companies with annual revenue between $300 million and $925 million and market capitalization between $250 million and $2.25 billion. As of September 2023, as compared to such peer groups, we were at the 27th percentile for revenue for the preceding 12 months, the 11th percentile for 30-day average market capitalization and the 20th percentile for EBITDA for the preceding 12 months.

Our peer group for 2024 included the following companies:

The peer group selected for 2024 reflected the following changes from our 2023 peer group:

In determining what changes to make to our peer group described above, the compensation committee removed the four companies identified above because they were acquired or had market values that were outliers. The companies identified above that were added to our peer group were added to balance out those companies that were removed and met most or all of the selection criteria. Changes were made to the peer group selection criteria for range multiples for revenue and market capitalization ranges.

In November 2023, Aon provided an analysis of data derived from members of our peer group and the Radford Global Compensation Database survey, the constituent companies of which were not provided to the compensation committee. For 2024, the compensation committee used Aon’s analysis to help structure a competitive executive compensation program, position executive compensation by considering market data, and make individual compensation decisions based on comparable positions at companies with which we compete for talent. Although the compensation committee does not establish compensation levels solely based on a review of competitive data or benchmark to any particular level, it believes such data is a useful tool in its deliberations as our compensation policies and practices must be competitive in the marketplace for us to be able to attract, motivate, and retain qualified executive officers.

Our compensation committee and Chief Executive Officer, as applicable, used benchmark data as a foundational starting point to determine target compensation for each NEO, and then adjusted the targets based on the NEO’s role criticality and incumbent performance. The benchmark data utilized was from our approved peer group based on relevant sector, revenue, market capitalization, and location, and was ultimately approved by the compensation committee.

1. Elements of Compensation

The primary elements of our NEOs’ compensation and the main objectives of each are:

Base Salary. Base salary attracts and retains talented executives, recognizes individual roles and responsibilities, and provides stable income.

Annual Performance-Based Incentive Compensation. Annual performance bonuses promote short-term performance objectives and reward executives for their contributions toward achieving those objectives.

Equity Based Long-Term Incentive Compensation. Equity compensation, provided in the form of time-based stock options and time-based and performance-based RSUs, aligns executives’ interests with our stockholders’ interests, emphasizes long-term financial and operational performance, and helps retain executive talent.

In addition, our NEOs are eligible to participate in our health and welfare programs and our 401(k) plan on the same basis as our other employees. We also maintain severance and change in control arrangements, which aid in attracting and retaining executive talent and help executives to remain focused and dedicated during potential transition periods due to a change in control. Each of these elements of compensation for 2024 is described further below.

Base Salary

The base salaries of our NEOs are an important part of their total compensation package and are intended to reflect their respective positions, duties, and responsibilities. Base salary is a visible and stable fixed component of our compensation program. Base salaries provide our NEOs with a reasonable degree of financial certainty and stability. With the goal of positioning base salaries at the median of market, our compensation committee, and with respect to our Chief Executive Officer, the Board, annually reviews and determines the base salaries of our executives and evaluates the base salaries of new hires at the time of hire. In March 2024, our compensation committee, and with respect to our Chief Executive Officer, the Board, determined that the base salaries in effect for each of our NEOs were below the median of market and, accordingly, increased the base salaries for each of Messrs. Bellm, Lentz, Klein, Dhatt, Cassidy, Eggerton and Sumrall from $490,000, $375,000, $400,000, $400,000, $300,000, $345,000 and $355,000, respectively to $509,600, $405,000, $415,000, $415,000, $325,000, $380,000, and $365,000 respectively, effective March 10, 2024.Mr. Hess’ employment commenced on May 28, 2024 with an initial base salary of $460,000. The base salaries paid to our NEOs in 2024 were as follows:

Cash Incentive Compensation

Annual cash incentive bonuses are an important component of our total compensation program and provide cash incentives that we believe are necessary to retain executive officers. During 2024, each NEO was eligible to receive an annual performance-based cash bonus under our 2024 Executive Bonus Plan based on a specified target annual bonus amount, expressed as a percentage of the named NEO’s base salary. We aim to award annual cash incentive bonuses that are between the 25th and 50th percentiles of market. Accordingly, following our review of the target bonus levels for each of our NEOs in March 2024, we determined that, for fiscal year 2024, our NEOs’ target annual bonuses would not be adjusted from their 2023 levels. Subsequently, we determined to increase Mr. Hess’ bonus target from 80% to 100% in connection with his promotion to Chief Executive Officer in October 2024. Our NEOs’ target annual bonuses for 2024 were equal to the following percentages of base salary:

At the beginning of 2024, the Board, considering the recommendations of the compensation committee and management, set the performance goals applicable to our 2024 annual bonus program. The performance goals established by the Board for our 2024 annual bonus program, and their respective weightings, were as follows:

For the year ended December 31, 2024, the Company attained a revenue growth rate of 7.6% resulting in achievement of the revenue growth rate performance goal at 76% of target, a subscription annual revenue run-rate growth rate of 3.2% resulting in achievement of the subscription annual revenue run-rate growth rate performance goal at 0% of target and an adjusted EBITDA of $23.5 million versus a target of $16.9 million resulting in achievement of the adjusted EBITDA performance goal at 200% of target. Based on the foregoing, the aggregate achievement of performance goals under the 2024 Executive Bonus Plan was approximately 92% of target, after giving effect to the Company’s financial performance thresholds described in the approved plan. See Appendix A for a reconciliation of adjusted EBITDA to the most directly comparable financial measure calculated and presented in accordance with GAAP.

The amounts of such bonuses paid to our NEOs in respect of 2024 are set forth in the column titled “Non-Equity Incentive Plan Compensation” in the 2024 Summary Compensation Table below. Mr. Bellm, Ms. Eggerton, and Mr. Sumrall did not receive a 2024 annual bonus payment because each of their employment with us ended prior to the payment of 2024 cash bonuses.

Retention Bonus

In November 2024, the compensation committee approved payment of a cash retention bonus for Mr. Lentz in an amount equal to $50,000 (the “Cash Bonus”), which is payable as to 25% of the Cash Bonus on or as soon as practicable after each of December 31, 2024, and March 31, 2025, and as to the remaining 50% of the Cash Bonus on or as soon as practicable after September 30, 2025 in each case, subject to Mr. Lentz’s continued employment with the Company through each such date. The Cash Bonus was awarded to incentivize Mr. Lentz’s retention during a period of significant executive turnover and during the Company’s transformation efforts.

Equity-Based Long-Term Incentive Awards

We view equity-based compensation as a critical component of our balanced total compensation program and aim to grant equity awards with target values between the 50th and 75th percentile of market. Equity-based compensation creates an ownership culture among our executives that provides an incentive to contribute to the continued growth and development of our business and aligns the interest of executives with those of our stockholders, reinforcing our commitment to ensuring a strong linkage between Company performance and pay.

Historically, our senior officers (including our NEOs) received equity-based compensation in the form of stock options and time-vesting RSUs. In March 2024, the compensation committee approved a change in the

structure of our long-term incentive compensation program for our senior officers (including our NEOs). The annual equity awards granted in 2024 to each NEO currently employed by us consisted of, and, going forward, the compensation committee intends to continue to grant our senior officers annual equity awards consisting of stock options, time-vesting RSUs and performance-based RSUs. We believe that including performance-based RSUs in our long-term incentive compensation program further aligns our NEOs’ interests with those of our stockholders and the performance of our Company, while encouraging our NEOs to contribute to the attainment of the relevant performance goals and increase total shareholder return (as further discussed below).

In 2024, we granted 70% of our target equity award value in the form of time- and performance-based RSUs (with time-based RSUs representing 51% of the total target annual equity award and performance-based RSUs representing 19% of the total target annual equity award) and 30% in the form of options to purchase our Common Stock for each of our NEOs other than Mr. Hess. In connection with the commencement of Mr. Hess' employment with us, he was granted equity awards in the form of time-based RSUs. In connection to his promotion to CEO in October 2024, he was awarded additional equity grants such that his total 2024 equity award target value was comprised of 80% RSUs (with time based RSUs and performance-based RSUs representing 91% and 9%, respectively, of his 2024 RSU awards total target value) and 20% in the form of options to purchase our Common Stock.

2024 Equity-Based Long-Term Incentive Awards

In 2024, we made the following grants of stock options, time-based RSUs and performance-based RSUs to our NEOs:

These grants (other than certain new hire and promotion grants for Mr. Hess and certain retention grants for Mr. Lentz, each as further discussed below) were approved by the compensation committee in March 2024, following consideration of the factors set forth above under “—Determination of Executive Compensation” above. Mr. Hess received a new hire award of 360,264 time-based RSUs in connection with the commencement of his employment with us in May 2024 and additional awards of (i) a stock option covering 100,000 shares of Common Stock and (ii) 100,000 PSUs in October 2024 in connection with his promotion to Chief Executive Officer. Mr. Lentz was granted an additional retention award in the form of a stock option covering 16,160 shares of our Common Stock in November 2024 (the “Retention Option”).

Stock Options and Time-Based RSU Awards

The stock options granted to our NEOs during 2024 (other than the Retention Option for Mr. Lentz) vest as to 25% of the underlying shares on the first anniversary of the applicable vesting start date and as to the balance of the underlying shares in 36 substantially equal monthly installments thereafter, subject to the applicable NEO’s continued service through the applicable vesting date. Mr. Lentz’s Retention Option vests as to 25% of the underlying shares on each of December 31, 2024, and March 31, 2025, and as to 50% of on September 30, 2025, subject to Mr. Lentz’s continued employment with the Company through the applicable vesting date.

The time-based RSU awards granted to our NEOs during 2024 vest as to 25% of the underlying shares on each of the first four anniversaries of the applicable vesting start date, subject to the applicable NEO’s continued service through the applicable vesting date.

Certain of our NEOs’ stock options and time-based RSUs are subject to accelerated vesting in certain circumstances, as described below under “—Potential Payments Upon Termination or Change in Control” below.

Performance-Based RSU Awards.

In March 2024 (or, for Mr. Hess, in October 2024), we granted awards of performance-based RSUs to our NEOs consisting of (i) performance-based RSUs subject to vesting based on the Company’s adjusted EBITDA (the “adjusted EBITDA RSUs”), (ii) performance-based RSUs subject to vesting based on the Company’s revenue (the “revenue RSUs”), and (iii) performance-based RSUs subject to vesting based on the Company’s TSR (the “TSR RSUs”), each as described below.

Adjusted EBITDA RSUs

Pursuant to the adjusted EBITDA RSU awards, each NEO is eligible to vest in a number of RSUs ranging from 0% to 200% of the target number of adjusted EBITDA RSUs granted, based on attainment of certain adjusted EBITDA goals during each year of a three-year performance period commencing January 1, 2024 and ending December 31, 2026. The compensation committee will determine the threshold, target and maximum adjusted EBITDA goals for each year of the performance period no later than 90 days following the beginning of such year.

Subject to the NEO’s continued service through the applicable vesting date, up to one-third of the total adjusted EBITDA RSUs will be eligible to vest based on the Company’s achievement of adjusted EBITDA goals for the applicable year, with the actual number of adjusted EBITDA RSUs that vest determined by multiplying (i) one-third of the total number of adjusted EBITDA RSUs (at target), by (ii) the applicable “vesting percentage,” as set forth below:

If the Company’s achievement of adjusted EBITDA goals for the applicable year falls between the levels specified above, the percentage of adjusted EBITDA RSUs that vest will be determined using straight line linear interpolation between such levels.

Following the completion of the applicable year, the compensation committee will determine achievement of the adjusted EBITDA goals for such year and the number of adjusted EBITDA RSUs that have become vested with respect to such year (the date of such determination by the compensation committee, the “adjusted EBITDA vesting date”). Any adjusted EBITDA RSUs eligible to vest on an adjusted EBITDA vesting date that do not vest will be forfeited without consideration therefore and the NEO will have no further right or interest in or with respect to such forfeited adjusted EBITDA RSUs.

Any adjusted EBITDA RSUs that become vested will be paid to the NEO in whole shares of Company Common Stock within 30 days after the applicable vesting date.

Revenue RSUs

Pursuant to the revenue RSU awards, each NEO is eligible to vest in a number of RSUs ranging from 0% to 200% of the target number of revenue RSUs granted, based on attainment of certain revenue goals during each year of a three-year performance period commencing January 1, 2024 and ending December 31, 2026. The compensation committee will determine the threshold, target and maximum revenue goals for each year of the performance period no later than 90 days following the beginning of such year.

Subject to the NEO’s continued service through the applicable vesting date, up to one-third of the total revenue RSUs will be eligible to vest based on achievement of the Company’s revenue goals for the applicable year, with the actual number of revenue RSUs that vest determined by multiplying (i) one-third of the total number of revenue RSUs (at target), by (ii) the applicable “vesting percentage,” as set forth below:

If the Company’s achievement of revenue goals for the applicable year falls between the levels specified above, the percentage of revenue RSUs that vest will be determined using straight line linear interpolation between such levels.

Following the completion of the applicable year, the compensation committee will determine achievement of the revenue goals for the applicable year and the number of revenue RSUs that have become vested with respect to such year (the date of such determination by the compensation committee, the “revenue vesting date”). Any revenue RSUs eligible to vest on a revenue vesting date that do not vest will be forfeited without consideration therefore and the NEO will have no further right or interest in or with respect to such forfeited revenue RSUs.

Any revenue RSUs that become vested will be paid to the NEO in whole shares of Company Common Stock within 30 days after the applicable vesting date.

TSR RSUs

Pursuant to the TSR RSU awards, each NEO is eligible to vest in a number of RSUs ranging from 0% to 200% of the target number of TSR RSUs granted, based on the Company’s total stockholder return during a three year performance period commencing January 1, 2024 and ending December 31, 2026 relative to the total stockholder return of the Russell 2000 Index (the “Russell 2000 Relative Performance”).

Subject to the NEO’s continued service through the applicable vesting date, up to 200% of the target number of TSR RSUs granted to the NEO will be eligible to vest based on the Russell 2000 Relative Performance during the performance period, with the actual number of TSR RSUs that vest with respect to the performance period determined by multiplying (i) the total number of TSR RSUs (at target), by (ii) the applicable “vesting percentage,” as set forth below:

If the Russell 2000 Relative Performance falls between the levels specified above, the percentage of TSR RSUs that vest will be determined using straight line linear interpolation between such levels. Notwithstanding the foregoing, if the Company’s absolute total stockholder return during the three-year performance period is negative, the vesting percentage will not exceed 100%.

Following the completion of the performance period, the Compensation Committee will determine the Russell 2000 Relative Performance, the absolute total shareholder return and the number of TSR RSUs that have become vested with respect to the performance period (the date of such determination by the Compensation Committee, the “TSR vesting date”). Any TSR RSUs that have not become vested as of the TSR vesting date will be forfeited without consideration therefore and the NEO will have no further right or interest in or with respect to such forfeited TSR RSUs.

Any TSR RSUs that become vested will be paid to the NEO in whole shares of Company Common Stock within 30 days after the applicable vesting date.

Certain of our NEOs’ performance-based RSUs are subject to accelerated vesting in certain circumstances, as described below under “—Potential Payments Upon Termination or Change in Control” below.

Performance-Based RSU Vesting Based on 2024 Performance

Adjusted EBITDA RSU Vesting

One-third of the adjusted EBITDA RSU awards granted to each of our NEOs in 2024 (the "First 2024 adjusted EBITDA Tranche") were eligible to vest based on achievement of adjusted EBITDA goals as of the end of the first year of the performance period, which commenced January 1, 2024 and ended December 31, 2024 (the "2024 Performance Year"). During the 2024 Performance Year, we achieved adjusted EBITDA of $23,547 resulting in the First 2024 adjusted EBITDA Tranche vesting at 200% of target.

Revenue RSU Vesting

One-third of the Revenue RSU awards granted to each of our NEOs in 2024 (the "First 2024 Revenue Tranche") were eligible to vest based on achievement of revenue goals as of the end of the 2024 Performance Year. During the 2024 Performance Year, we achieved revenue of $332,927 resulting in the First 2024 Revenue Tranche vesting at 89% of target.

Retirement Savings, Health and Welfare Benefits

We maintain a 401(k) retirement savings plan for our employees, including our NEOs, who satisfy certain eligibility requirements. Our NEOs are eligible to participate in the 401(k) plan on the same terms as other full-time employees. The Code allows eligible employees to defer a portion of their compensation, within prescribed limits, on a pre-tax basis through contributions to the 401(k) plan. In 2024, we did not match contributions made by participants in the 401(k) plan. We believe that providing a vehicle for tax-deferred retirement savings through our 401(k) plan adds to the overall desirability of our executive compensation package and further incentivizes our employees, including our NEOs, in accordance with our compensation policies.

Employee Benefits and Perquisites

All of our full-time employees, including our NEOs, are eligible to participate in our health and welfare plans, including medical, dental, and vision benefits, medical and dependent care flexible spending accounts, short-term and long-term disability insurance, and life insurance. We believe the benefits described above are necessary and appropriate to provide a competitive compensation package to our NEOs.

We do not currently provide perquisites to our NEOs, and we do not view perquisites or other personal benefits as a significant component of our executive compensation program. In the future, we may provide perquisites or other personal benefits in limited circumstances, such as where we believe it is appropriate to assist an individual executive officer in the performance of the executive’s duties, to make our executive officers more efficient and effective, and for recruitment, motivation, or retention purposes. All future practices with respect to perquisites or other personal benefits will be approved by the compensation committee.

We do not provide any tax “gross ups” to our NEOs.

Severance and Change in Control Arrangements

We provide for severance benefits and payments to each of our NEOs upon certain terminations without cause or resignations for good reason. Our compensation committee believes that these types of benefits are necessary to attract and retain executive talent and are a customary component of executive compensation. In particular, such benefits can mitigate a potential disincentive for our NEOs when they are evaluating a potential acquisition of the Company and can encourage retention through the conclusion of the transaction. Our severance and change in control payments and benefits are designed to be competitive with market practices. A description of these potential benefits, as well as information on the estimated payments and benefits that our NEOs would have

been eligible to receive if a qualifying termination of employment or change in control had occurred on December 31, 2024, are set forth in “—Potential Payments Upon Termination or Change in Control” below.

On November 6, 2024, September 30, 2024, and August 5, 2024, respectively, we entered into separation and general releases (the “separation agreement”) with Mr. Bellm, Ms. Eggerton, and Mr. Sumrall, in connection with their respective terminations of employment with us. Under the separation agreements, Mr. Bellm, Ms. Eggerton, and Mr. Sumrall became entitled to certain severance payments and benefits, subject to the applicable NEO's execution and non-revocation of the separation agreement, including the general release contained therein, and compliance with the terms thereof. A description of these severance payments and benefits are set forth in “—Potential Payments Upon Termination or Change in Control” below.

Stock Ownership Guidelines. We believe that stock ownership aligns the interests of our executive officers with our stockholders and encourages long-term management of the Company for the benefit of its stockholders. We maintain stock ownership guidelines which apply to our senior leadership team. Under these guidelines, our senior leaders are required to acquire and maintain shares of our Common Stock having a value equal to the following multiples of their annual base salaries following the completion of a five-year phase-in period:

Derivatives Trading, Hedging, and Pledging Policies. We have adopted an Insider Trading Compliance Policy that governs the purchase, sale, and other dispositions of the Company’s securities by directors, officers and employees that is reasonably designed to promote compliance with insider trading laws, rules and regulations, and any listing standards applicable to the Company. Our Insider Trading Compliance Policy provides that no employee, officer, or director may engage in any activity of the type that is designed to profit from or hedge against decreases in the value of the Company’s securities, such as short sales, trading activity designed to profit from fluctuations in the price of the Company’s securities (such as day trading and arbitrage trading), hedging transactions, and trading in puts, calls or other derivative securities. In addition, our Insider Trading Compliance Policy provides that no employee, officer, or director may pledge Company securities as collateral to secure loans. This prohibition means, among other things, that these individuals may not hold Company securities in a “margin” account, which would allow the individual to borrow against their holdings to buy securities.

Clawback Policy. We maintain a mandatory clawback policy in compliance with SEC rules and Nasdaq listing standards (the “Clawback Policy”). Our Clawback Policy provides that the Company shall recover from current or former executive officers excess incentive-based compensation (i.e., incentive compensation that is granted, earned or vested based in whole or in part on the attainment of one or more financial reporting measures) in the event the Company is required to prepare an accounting restatement, unless the compensation committee determines that recovery would be impracticable.

Section 409A. The compensation committee takes into account whether components of the compensation for our executive officers will be adversely impacted by the penalty tax imposed by Section 409A of the Code, and

aims to structure these components to be compliant with or exempt from Section 409A to avoid such potential adverse tax consequences.

Section 162(m). Section 162(m) of the Code disallows a tax deduction to public companies for compensation in excess of $1 million paid to “covered employees”, which generally includes all NEOs. While the compensation committee may take the deductibility of compensation into account when making compensation decisions, the compensation committee will award compensation that it determines to be consistent with the goals of our executive compensation program even if such compensation is not deductible by us.

“Golden Parachute” Payments. Sections 280G and 4999 of the Code provide that certain executive officers and other service providers who are highly compensated or hold significant equity interests may be subject to an excise tax if they receive payments or benefits in connection with a change in control of the Company that exceeds certain prescribed limits, and that we, or a successor, may forfeit a tax deduction on the amounts subject to this additional tax. While the compensation committee may take the potential forfeiture of such tax deduction into account when making compensation decisions, it will award compensation that it determines to be consistent with the goals of our executive compensation program even if such compensation is not deductible by us. We do not provide any tax gross-ups to cover excise taxes under Section 4999 in connection with a change in control.

Accounting for Share-Based Compensation. We follow Financial Accounting Standard Board Accounting Standards Codification Topic 718, (“ASC Topic 718”), for our share-based compensation awards. ASC Topic 718 requires companies to measure the compensation expense for all share-based payment awards made to employees and directors, including stock options and RSUs, based on the grant date “fair value” of these awards. This calculation is performed for accounting purposes and reported in the compensation tables below, even though our NEOs may never realize any value from their awards.

COMPENSATION COMMITTEE REPORT

The compensation committee reviewed and discussed the foregoing Compensation Discussion and Analysis with the Company’s management. Based on this review and discussion with management, the compensation committee recommended to the Board of Directors that the Compensation Discussion and Analysis be included in this Proxy Statement and incorporated by reference into the Company’s Annual Report on Form 10-K for the year ended December 31, 2024, filed by us with the SEC.

This report of the compensation committee is not “soliciting material,” shall not be deemed “filed” with the SEC and shall not be incorporated by reference by any general statement incorporating by reference this Proxy Statement into any filing under the Securities Act of 1933, as amended, or the Securities Exchange Act of 1934, as amended, whether made before or after the date hereof and irrespective of any general incorporation language in any such filing, except to the extent that we specifically incorporate this information by reference, and shall not otherwise be deemed filed under such acts.

The foregoing report has been furnished by the compensation committee.

Respectfully submitted,
