I am pleased to invite you to attend the 2023 Annual Meeting of Stockholders, or the Annual Meeting, of Markforged Holding Corporation, or Markforged, to be held online on June 20, 2023, at 9 a.m. Eastern Time. You may attend the meeting virtually via the Internet at www.virtualshareholdermeeting.com/MKFG2023, where you will be able to vote electronically and submit questions. Details regarding the meeting and the business to be conducted are more fully described in the accompanying Notice of 2023 Annual Meeting of Stockholders and Proxy Statement.

Pursuant to the Securities and Exchange Commission rules that allow issuers to furnish proxy materials to stockholders over the Internet, we are posting the proxy materials on the Internet and delivering a notice of the Internet availability of the proxy materials. On or about April 28, 2023, we will begin mailing to our stockholders a Notice of Internet Availability of Proxy Materials, or the Notice, containing instructions on how to access online or request a printed copy of our Proxy Statement for the 2023 Annual Meeting of Stockholders and our Annual Report on Form 10-K for the year ended December 31, 2022.

Your vote is important. Whether or not you plan to attend the Annual Meeting, I hope you will vote as soon as possible. You may vote over the Internet, by telephone or virtually in person at the Annual Meeting or, if you requested printed copies of proxy materials, you also may vote by mailing a proxy card. Please review the instructions on the Notice or on the proxy card regarding your voting options.

Thank you for being a Markforged stockholder. We look forward to seeing you at our Annual Meeting.

In order to ensure your representation at the meeting, whether or not you plan to attend the meeting, please vote your shares as promptly as possible by following the instructions on your Notice or, if you requested printed copies of your proxy materials, by following the instructions on your proxy card. Your vote will help to ensure the presence of a quorum at the meeting, meaning that your shares are represented at the Annual Meeting. If you hold your shares through a broker, your broker is not permitted to vote on your behalf on the election of directors unless you provide specific instructions to the broker by completing and returning any voting instruction form that the broker provides (or following any instructions that allow you to vote your broker-held shares via telephone or the Internet). For your vote to be counted, you will need to communicate your vote before the date of the Annual Meeting. Voting your shares in advance will not prevent you from attending the Annual Meeting, revoking your earlier submitted proxy, or voting your stock virtually at the Annual Meeting.

Notice is hereby given that Markforged Holding Corporation will hold its 2023 Annual Meeting of Stockholders, or the Annual Meeting, online on June 20, 2023 at 9:00 a.m. Eastern Time, for the following purposes:

Our board of directors recommends that you vote “FOR” the director nominees named in Proposal No. 1, and “FOR” the ratification of the appointment of PricewaterhouseCoopers LLP as our independent registered public accounting firm as described in Proposal No. 2.

Only stockholders of record at the close of business on April 21, 2023 are entitled to notice of and to vote at the Annual Meeting as set forth in the Proxy Statement. You may attend, vote and participate at the Annual Meeting by visiting www.virtualshareholdermeeting.com/MKFG2023 and entering the 16-digit control number included in the Notice of Internet Availability of Proxy Materials, on the proxy card, or in the instructions included with the proxy materials dated April 28, 2023. You are entitled to attend the Annual Meeting only if you were a stockholder as of the close of business on April 21, 2023 or hold a valid proxy for the Annual Meeting. If you are a stockholder of record or hold shares through a broker, trustee, or nominee, your ownership as of the record date will be verified prior to admittance into the meeting. Access to the webcast will begin at 8:00 a.m. Eastern Time on June 20, 2023. For instructions on how to vote your shares, please refer to the instructions on the Notice of Availability of Proxy Materials you received in the mail, the section titled “How do I vote?” beginning on page 2 of this Proxy Statement or, if you requested to receive printed proxy materials, your enclosed proxy card.

This proxy statement contains information about the 2023 Annual Meeting of Stockholders, or the Annual Meeting, of Markforged Holding Corporation, which will be held online on June 20, 2023, at 9:00 a.m. Eastern Time. You may attend the meeting virtually via the Internet at www.virtualshareholdermeeting.com/MKFG2023, where you will be able to vote electronically and submit questions. The board of directors of Markforged Holding Corporation is using this proxy statement to solicit proxies for use at the Annual Meeting. In this proxy statement, the terms “Markforged,” “we,” “us,” and “our” refer to Markforged Holding Corporation. The mailing address of our principal executive offices is Markforged Holding Corporation, 60 Tower Road, Waltham, Massachusetts 02451.

All properly submitted proxies will be voted in accordance with the instructions contained in those proxies. If no instructions are specified, the proxies will be voted in accordance with the recommendation of our board of directors with respect to each of the matters set forth in the accompanying Notice of Meeting. You may revoke your proxy at any time before it is exercised at the meeting by giving our corporate secretary written notice to that effect.

We made this proxy statement and our Annual Report to Stockholders for the fiscal year ended December 31, 2022 available to stockholders on April 28, 2023.

We are an “emerging growth company” under applicable federal securities laws and therefore permitted to conform with certain reduced public company reporting requirements. As an emerging growth company, we provide in this proxy statement the scaled disclosure permitted under the Jumpstart Our Business Startups Act of 2012 (the JOBS Act), including the compensation disclosures required of a “smaller reporting company,” as that term is defined in Rule 12b2 promulgated under the Securities Exchange Act of 1934, as amended (the Exchange Act). In addition, as an emerging growth company, we are not required to conduct votes seeking approval, on an advisory basis, of the compensation of our named executive officers or the frequency with which such votes must be conducted. We will remain an “emerging growth company” until the earliest of: (i) December 31, 2025; (ii) the last day of the fiscal year in which our total annual gross revenue is equal to or more than $1.235 billion; (iii) the date on which we have issued more than $1.0 billion in nonconvertible debt during the previous three years; or (iv) the date on which we are deemed to be a large accelerated filer under the rules of the Securities and Exchange Commission. Even after we are no longer an “emerging growth company,” we may remain a “smaller reporting company.”

A copy of our Annual Report on Form 10-K for the fiscal year ended December 31, 2022, as filed with the Securities and Exchange Commission (SEC), except for exhibits, will be furnished without charge to any stockholder upon written request to Markforged Holding Corporation, 60 Tower Road, Waltham, Massachusetts 02451, Attention: Corporate Secretary or by email to investors@markforged.com. This proxy statement and our Annual Report on Form 10-K for the fiscal year ended December 31, 2022 are also available on the SEC’s website at www.sec.gov.

When are this proxy statement and the accompanying materials scheduled to be sent to stockholders?

We have elected to provide access to our proxy materials to our stockholders via the Internet. Accordingly, on or about April 28, 2023, we will begin mailing a Notice of Internet Availability of Proxy Materials, or Notice. Our proxy materials, including the Notice of 2023 Annual Meeting of Stockholders, this proxy statement and the accompanying proxy card or, for shares held in street name (i.e., held for your account by a broker or other nominee), a voting instruction form, and the 2023 Annual Report to Stockholders, or 2023 Annual Report, will be mailed or made available to stockholders on the Internet on or about the same date.

Why did I receive a Notice of Internet Availability of Proxy Materials instead of a full set of proxy materials?

Pursuant to rules adopted by the Securities and Exchange Commission, or SEC, for most stockholders, we are providing access to our proxy materials over the Internet rather than printing and mailing our proxy materials. We believe following this process will expedite the receipt of such materials, help lower our costs, and will reduce the environmental impact of our annual meeting materials. Therefore, the Notice was mailed to holders of record and beneficial owners of our common stock starting on or about April 28, 2023. The Notice provides instructions as to how stockholders may access and review our proxy materials, including the Notice of 2023 Annual Meeting of Stockholders, this proxy statement, the proxy card and our 2023 Annual Report, on the website referred to in the Notice or, alternatively, how to request that a copy of the proxy materials, including a proxy card, be sent to them by mail. The Notice also provides voting instructions. In addition, stockholders of record may request to receive the proxy materials in printed form by mail or electronically by e-mail on an ongoing basis for future stockholder meetings. Please note that, while our proxy materials are available at the website referenced in the Notice, and our Notice of 2023 Annual Meeting of Stockholders, this proxy statement and our 2023 Annual Report are available on our website, no other information contained on either website is incorporated by reference in or considered to be a part of this proxy statement.

The record date for determination of stockholders entitled to vote at the Annual Meeting was the close of business on April 21, 2023.

There were 196,323,235 shares of our common stock, par value $0.0001 per share, outstanding on April 21, 2023, all of which are entitled to vote with respect to all matters to be acted upon at the Annual Meeting. Each stockholder of record is entitled to one vote for each share of our common stock held by such stockholder. None of our shares of preferred stock were outstanding as of April 21, 2023.

If you are a stockholder of record, you may vote virtually in person at the Annual Meeting. You may attend the Annual Meeting virtually via the internet at www.virtualshareholdermeeting.com/MKFG2023 and you may vote during the meeting. Access to the webcast will begin at 8:00 a.m. Eastern Time on June 20, 2023. In order to be able to attend the Annual Meeting, you will need the 16-digit control number, provided in the Notice of Internet Availability of Proxy Materials, on the proxy card, or in the instructions included with the proxy materials dated April 28, 2023. If you hold your shares through a bank or broker and wish to vote in person at the meeting, you must obtain a valid proxy from the firm that holds your shares.

If you do not wish to vote virtually in person or will not be attending the Annual Meeting, you may vote by proxy. You can vote by proxy over the Internet by following the instructions provided in the Notice, or, if you requested printed copies of the proxy materials by mail, you can vote by mailing your proxy as described in the proxy materials. In order to be counted, proxies submitted by Internet or phone must be received by the cutoff time of 11:59 p.m. Eastern Time on June 19, 2023. Proxies submitted by mail must be received before the start of the Annual Meeting.

If you complete and submit your proxy before the Annual Meeting, the persons named as proxies will vote the shares represented by your proxy in accordance with your instructions. If you submit a proxy without giving voting instructions, your shares will be voted in the manner recommended by the Board of Directors on all matters presented in this proxy statement, and as the persons named as proxies may determine in their discretion with respect to any other matters properly presented at the Annual Meeting. You may also authorize another person or persons to act for you as proxy in a writing, signed by you or your authorized representative, specifying the details of those proxies’ authority. The original writing must be given to each of the named proxies, although it may be sent to them by electronic transmission if, from that transmission, it can be determined that the transmission was authorized by you.

If any other matters are properly presented for consideration at the Annual Meeting, including, among other things, consideration of a motion to adjourn the Annual Meeting to another time or place (including, without limitation, for the purpose of soliciting additional proxies), the persons named in your proxy and acting thereunder will have discretion to vote on those matters in accordance with their best judgment. We do not currently anticipate that any other matters will be raised at the Annual Meeting.

You may vote over the internet or by telephone by following the instructions provided on the Notice.

You may revoke your proxy by (1) following the instructions on the Notice and entering a new vote by mail that we receive before the start of the Annual Meeting or over the Internet or by phone by the cutoff time of 11:59 p.m. Eastern Time on June 19, 2023, (2) attending and voting virtually at the Annual Meeting (although attendance at the Annual Meeting will not in and of itself revoke a proxy), or (3) by filing an instrument in writing revoking the proxy or another duly executed proxy bearing a later date with our Corporate Secretary. Any written notice of revocation or subsequent proxy card must be received by our Corporate Secretary prior to the taking of the vote at the Annual Meeting. Such written notice of revocation or subsequent proxy card should be hand delivered to our Corporate Secretary or sent to our principal executive offices at Markforged Holding Corporation 60 Tower Road, Waltham, Massachusetts 02451, Attention: Corporate Secretary.

If a broker, bank, or other nominee holds your shares, you must contact such broker, bank, or nominee in order to find out how to change your vote.

Our bylaws provide that a majority of the shares entitled to vote, present in person or by remote communication, or represented by proxy, will constitute a quorum for the transaction of business at the Annual Meeting.

Under the General Corporation Law of the State of Delaware, shares that are voted “abstain” or “withheld” and broker “non-votes” are counted as present for purposes of determining whether a quorum is present at the Annual Meeting. If a quorum is not present, the meeting may be adjourned until a quorum is obtained.

Under our bylaws, any proposal other than an election of directors is decided by a majority of the votes properly cast for and against such proposal, except where a larger vote is required by law or by our certificate of incorporation or bylaws. Abstentions and broker “non-votes” are not included in the tabulation of the voting results on any such proposal and, therefore, do not have an impact on such proposals. A broker “non-vote” occurs when a nominee holding shares for a beneficial owner does not vote on a particular proposal

because the nominee does not have discretionary voting power with respect to that item and has not received instructions from the beneficial owner.

If your shares are held in “street name” by a brokerage firm, your brokerage firm is required to vote your shares according to your instructions. If you do not give instructions to your brokerage firm, the brokerage firm will still be able to vote your shares with respect to certain “discretionary” item, but will not be allowed to vote your shares with respect to “non-discretionary” items. Proposal No. 1 is a “non-discretionary” item. If you do not instruct your broker how to vote with respect to this proposal, your broker may not vote for this proposal, and those votes will be counted as broker “non-votes.” Proposal No. 2 is considered to be a discretionary item, and your brokerage firm will be able to vote on this proposal even if it does not receive instructions from you.

To be elected, the directors nominated via Proposal No. 1 must receive a plurality of the votes properly cast on the election of directors, meaning that the director nominees receiving the most votes will be elected. Shares voting “withheld” have no effect on the election of directors.

We are making this solicitation and will pay the entire cost of preparing and distributing the Notice and our proxy materials and soliciting votes. If you choose to access the proxy materials or vote over the Internet, you are responsible for any Internet access charges that you may incur. Our officers and employees may, without compensation other than their regular compensation, solicit proxies through further mailings, personal conversations, facsimile transmissions, e-mails, or otherwise. We have hired Broadridge Financial Solutions, Inc. to assist us in the distribution of proxy materials. Proxy solicitation expenses that we will pay include those for preparation, mailing, returning, and tabulating the proxies.

We plan to announce preliminary voting results at the Annual Meeting and will publish final results in a Current Report on Form 8-K to be filed with the SEC within four business days following the Annual Meeting.

Our board of directors currently consists of eight members. In accordance with the terms of our certificate of incorporation and bylaws, our board of directors is divided into three classes, Class I, Class II and Class III, with members of each class serving staggered three-year terms. The members of the classes are divided as follows:

Upon the expiration of the term of a class of directors, directors in that class will be eligible to be elected for a new three-year term at the annual meeting of stockholders in the year in which their term expires.

Our board of directors has nominated Paul Milbury and Shai Terem for election as the Class II directors at the Annual Meeting. The nominees are presently directors and have indicated a willingness to continue to serve as directors, if elected. If the nominees become unable or unwilling to serve, however, the proxies may be voted for a substitute nominee selected by our board of directors.

The following table identifies our directors and sets forth their principal occupation and business experience during the last five years and their ages as of June 1, 2023.

Shai Terem has been our President and Chief Executive Officer and a member of our board of directors since July 2021. Mr. Terem has also served as President, Chief Executive Officer, and director of MarkForged, Inc. from October 2020 until July 2021.

From October 2014 to February 2017, Mr. Milbury was Director and Audit Committee Chair of SimpliVity Corporation. Mr. Milbury holds a B.B.A. and an M.B.A. from the University of Massachusetts, Amherst. We believe that Mr. Milbury’s extensive financial expertise qualifies him to serve on our board of directors.

The proxies will be voted in favor of the above nominees unless a contrary specification is made in the proxy. The nominees have consented to serve as our directors if elected. However, if the nominees are unable to serve or for good cause will not serve as a director, the proxies will be voted for the election of such substitute nominee as our board of directors may designate.

The board of directors recommends voting “FOR” the election of Paul Milbury and Shai Terem as the Class II directors, to serve for a three-year term ending at the annual meeting of stockholders to be held in 2026.

Markforged’s stockholders are being asked to ratify the appointment by the audit committee of the Markforged board of directors of PricewaterhouseCoopers LLP, as Markforged’s independent registered public accounting firm for the fiscal year ending December 31, 2023. PricewaterhouseCoopers LLP has served as independent registered public accounting firm for MarkForged, Inc. since 2019 and for Markforged Holding Corporation since 2021.

The audit committee is solely responsible for selecting Markforged’s independent registered public accounting firm for the fiscal year ending December 31, 2023. Stockholder approval is not required to appoint PricewaterhouseCoopers LLP as Markforged’s independent registered public accounting firm. However, the board of directors believes that submitting the appointment of PricewaterhouseCoopers LLP to the stockholders for ratification is good corporate governance. If the stockholders do not ratify this appointment, the audit committee will reconsider whether to retain PricewaterhouseCoopers LLP. If the selection of PricewaterhouseCoopers LLP is ratified, the audit committee, at its discretion, may direct the appointment of a different independent registered public accounting firm at any time it decides that such a change would be in the best interest of Markforged Holding Corporation and its stockholders.

A representative of PricewaterhouseCoopers LLP is expected to be present at the Annual Meeting and will have an opportunity to make a statement if he or she desires to do so and to respond to appropriate questions from our stockholders.

Markforged incurred the following fees from PricewaterhouseCoopers LLP for the audit of the consolidated financial statements and for other services provided for the fiscal years ended December 31, 2022 and 2021.

(1)

Audit fees consist of fees for professional services performed for the audit of our annual financial statements and the required review of quarterly financial statements and other procedures performed by the independent registered accounting firm in order for them to be able to form an opinion on our consolidated financial statements. These fees also cover services that are normally provided by independent registered accounting firm in connection with statutory and regulatory filings or engagements.

(2)

Audit-related fees consist of fees for assurance and related services that traditionally are performed by independent registered accounting firm that are reasonably related to the performance of the audit or review of the financial statements. Audit related fees in the above table represent fees related to SEC filings other than the Form 10-K and Form 10-Q.

(3)

Tax fees consist of fees for all professional services performed by professional staff in our independent registered accounting firm, except those services related to the audit of our financial statements. These include fees for tax compliance, tax planning and tax advice, including federal, state and local issues. Services may also include assistance with tax audits and appeals before the IRS and similar state and local agencies, as well as federal, state and local tax issues related to due diligence.

Our audit committee has adopted policies and procedures relating to the approval of all audit and non-audit services that are to be performed by our independent registered public accounting firm. This policy provides that we will not engage our independent registered public accounting firm to render audit or non-audit services unless the service is specifically approved in advance by our audit committee or the engagement is entered into pursuant to the pre-approval procedure described below.

From time to time, our audit committee may pre-approve specified types of services that are expected to be provided to us by our independent registered public accounting firm during the next 12 months. Any such pre-approval details the particular service or type of services to be provided and is also generally subject to a maximum dollar amount.

During our 2022 and 2021 fiscal years, no services were provided to us by PricewaterhouseCoopers LLP other than in accordance with the pre-approval policies and procedures described above.

The board of directors recommends voting “FOR” Proposal No. 2 to ratify the appointment of PricewaterhouseCoopers LLP as Markforged’s independent registered public accounting firm for the fiscal year ending December 31, 2023.

Our nominating and corporate governance committee is responsible for identifying individuals qualified to become members of our board of directors, consistent with criteria approved by our board, and recommending such persons to be nominated for election as directors, except where we are legally required by contract, law or otherwise to provide third parties with the right to nominate.

The process followed by our nominating and corporate governance committee to identify and evaluate director candidates includes requests for recommendations from non-management directors, the Chief Executive Officer, other executive officers, third-party search firms and any other source the nominating and corporate governance committee deems appropriate. The qualifications, qualities and skills that our nominating and corporate governance committee believes must be met by a committee-recommended nominee for a position on our board of directors are as follows:

Any such proposals should be submitted to our corporate secretary at our principal executive offices no later than the close of business on the 90th day nor earlier than the close of business on the 120th day prior to the one-year anniversary of the date of the preceding year’s annual meeting and should include appropriate biographical and background material to allow the nominating and corporate governance committee to properly evaluate the potential director candidate and the number of shares of our stock beneficially owned by the stockholder proposing the candidate. Stockholder proposals should be addressed to Markforged Holding Corporation, 60 Tower Road, Waltham, Massachusetts 02451, Attention: Corporate Secretary. Assuming that biographical and background material has been provided on a timely basis in accordance with our bylaws, any recommendations received from stockholders will be evaluated in the same manner as potential nominees proposed by the nominating and corporate governance committee. If our board of directors determines to nominate a stockholder-recommended candidate and recommends his or her election, then his or her name will be included on our proxy card for the next annual meeting of stockholders. See “Stockholder Proposals” for a discussion of submitting stockholder proposals.

Our board of directors has undertaken a review of the independence of each director. Based on information provided by each director concerning his or her background, employment and affiliations, our board of directors has determined that each of Edward Anderson, Kevin E. Hartz, Michael Medici, Paul Milbury, Antonio Rodriguez, Carol Meyers and Alan Masarek qualifies as “independent” as defined under applicable SEC rules and NYSE listing standards. In making these determinations, our board of directors considered the current and prior relationships that each non-employee director has with our company and all other facts and circumstances our board of directors deemed relevant in determining their independence and eligibility to serve on the committees of our board of directors, including the transactions involving them described in the section titled “Certain Relationships and Related Party Transactions.”

Our board of directors has established a standing audit committee, a compensation committee and a nominating and corporate governance committee. Each of the audit committee, compensation committee, and nominating and corporate governance committee operates under a charter that satisfies the applicable standards of the SEC and NYSE. Each such committee reviews its respective charter at least annually. A current copy of the charter for each of the audit committee, compensation committee, and nominating and corporate governance committee is posted on the governance section of our website, https://investors.markforged.com.

Paul Milbury, Edward Anderson and Michael Medici serve on the audit committee, which is chaired by Mr. Milbury. Our board of directors has determined that each member of the audit committee is “independent” for audit committee purposes as that term is defined in the rules of the SEC and the applicable NYSE rules, and each has sufficient knowledge in financial and auditing matters to serve on the audit committee. Our board of directors has designated Mr. Milbury as an “audit committee financial expert,” as defined under the applicable rules of the SEC. During the fiscal year ended December 31, 2022, the audit committee met three times. The report of the audit committee is included in this proxy statement under “Report of the Audit Committee.” The audit committee’s responsibilities include:

Edward Anderson, Kevin Hartz and Carol Meyers serve on the compensation committee, which is chaired by Mr. Anderson. Our board of directors has determined that each member of the compensation committee meets the requirements of a “non-employee director” pursuant to Rule 16b-3 under the Exchange Act. Our board of directors has determined that each member of the compensation committee is “independent” for compensation committee purposes as that term is defined in the rules of the SEC and the applicable NYSE rules. During the fiscal year ended December 31, 2022, the compensation committee met seven times. The compensation committee’s responsibilities include:

Michael Medici, Alan Masarek and Antonio Rodriguez serve on the nominating and corporate governance committee, which is chaired by Mr. Medici. Our board of directors has determined that each member of the nominating and corporate governance committee is “independent” for nominating and corporate governance committee purposes as that term is defined in the rules of the SEC and the applicable NYSE rules. During the fiscal year ended December 31, 2022, the nominating and corporate governance committee met four times. The nominating and corporate governance committee’s responsibilities include:

The nominating and corporate governance committee considers candidates for membership to our board of directors suggested by our board members, including our Chief Executive Officer. Additionally, in selecting nominees for directors, the nominating and corporate governance committee will review candidates properly recommended by stockholders in the same manner and using the same general criteria as candidates recruited by the committee and/or recommended by our board of directors. Any stockholder who wishes to recommend a candidate for consideration by the committee as a nominee for director should follow the procedures described in this proxy statement under the heading “Stockholder Proposals.”

Identifying and Evaluating Director Nominees. Our board of directors is responsible for filling vacancies on our board of directors and for nominating candidates for election by our stockholders each year in the class of directors whose term expires at the relevant annual meeting. The board of directors delegates the selection and nomination process to the nominating and corporate governance committee, with the expectation that other members of the board of directors, and of management, will be requested to take part in the process as appropriate.

Generally, the nominating and corporate governance committee identifies candidates for director nominees in consultation with other members of our board of directors, with management, through the use of search firms or other advisors, through the recommendations submitted by stockholders or through such other methods as the nominating and corporate governance committee deems to be helpful to identify candidates. Once candidates have been identified, the nominating and corporate governance committee confirms that the candidates meet all of the minimum qualifications for director nominees established by the nominating and corporate governance committee. The nominating and corporate governance committee may gather information about the candidates through interviews, detailed questionnaires, comprehensive background checks or any other means that the nominating and corporate governance committee deems to be appropriate in the evaluation process. The nominating and corporate governance committee then meets as a group to discuss and evaluate the qualities and skills of each candidate, both on an individual basis and taking into account the overall composition and needs of our board of directors. Based on the results of the evaluation process, the nominating and corporate governance committee recommends candidates for the board of directors’ approval to fill a vacancy or as director nominees for election to the board of directors by our stockholders each year in the class of directors whose term expires at the relevant annual meeting.

Our board of directors met ten times during fiscal year 2022. During fiscal year 2022, each member of the board of directors attended in person or participated in 75% or more of the aggregate of (i) the total number of meetings of the board of directors (held during the period for which such person has been a director) and (ii) the total number of meetings held by all committees of the board of directors on which such person served (during the periods that such person served), with the exception of Alan Masarek.

Directors are responsible for attending the annual meeting of stockholders to the extent practicable. Alan Masarek, Carol Meyers, Paul Milbury, and Antonio Rodriguez attended our annual meeting of stockholders held in June 2022.

Certain transactions in our securities (such as purchases and sales of publicly traded put and call options, and short sales) create a heightened compliance risk or could create the appearance of misalignment between management and stockholders. In addition, securities held in a margin account or pledged as collateral may be sold without consent if the owner fails to meet a margin call or defaults on the loan, thus creating the risk that a sale may occur at a time when an officer or director is aware of material, nonpublic information or otherwise is not permitted to trade in Company securities. Our insider trading policy expressly prohibits short sales and derivative transactions of our stock by our officers, directors, employees and certain designated consultants and contractors, including short sales of our securities and the purchase or sale of puts, calls, or other derivative securities of the company or any derivative securities that provide the economic equivalent of ownership. Any waiver of this policy requires the approval of our audit committee. To date, no such requests have been made or approved.

We have adopted a written code of business conduct and ethics that applies to our directors, officers and employees, including our principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions. A current copy of the code is posted on the governance section of our website, which is located at https://investors.markforged.com. We intend to disclose any amendment or waiver of a provision of our Code of Business Conduct and Ethics that applies to our principal executive officer, principal financial officer, or persons performing similar functions, by posting such information on our website available at https://investors.markforged.com and/or our public filings with the SEC.

We have adopted Corporate Governance Guidelines to assist with the exercise of our duties and responsibilities and to serve the best interests of the Company and its stockholders. The Board, with the assistance of the Nominating and Corporate Governance Committee, continuously evaluates the Company’s Corporate Governance Guidelines to ensure such guidelines are effectively serving the interests of the Company’s stockholders and are up-to-date with respect to current corporate governance best practices. A current copy of our Corporate Governance Guidelines is posted on the governance section of our website, which is located at https://investors.markforged.com.

Currently, the role of Chairman of the board is separated from the role of Chief Executive Officer. We believe that separating these positions allows our Chief Executive Officer to focus on our day-to-day business, while allowing the Chairman of the Board to lead the board of directors in its fundamental role of providing advice to, and independent oversight, of management. Our board of directors recognizes the time, effort, and energy that the Chief Executive Officer is required to devote to his position in the current business environment, as well as the commitment required to serve as our Chairman, particularly as the board of directors’ oversight responsibilities continue to grow. While our bylaws and our corporate governance guidelines do not require that our Chairman and Chief Executive Officer positions be separate, our board of directors believes that having separate positions is the appropriate leadership structure for us at this time and demonstrates our commitment to good corporate governance.

Risk is inherent to every business, and how well a business manages risk can ultimately determine its success. We face a number of risks, including risks relating to our financial condition, development and commercialization activities, operations, strategic direction, and intellectual property. Management is responsible for the day-to-day management of risks we face, while our board of directors, as a whole and through its committees, has responsibility for the oversight of risk management. In its risk oversight role, our board of directors has the responsibility to satisfy itself that the risk management processes designed and implemented by management are adequate and functioning as designed.

The role of the board of directors in overseeing the management of our risks is conducted primarily through committees of the board of directors, as disclosed in the descriptions of each of the committees above and in the charters of each of the committees. The full board of directors (or the appropriate board committee in the case of risks that are under the purview of a particular committee) discusses with management our major risk exposures, their potential impact on us, and the steps we take to manage them. When a board committee is responsible for evaluating and overseeing the management of a particular risk or risks, the Chairman of the relevant committee reports on the discussion to the full board of directors. This enables the board of directors and its committees to coordinate the risk oversight role, particularly with respect to risk interrelationships.

We are committed to making a positive global impact today and will continue to assess and enhance our environmental, social and governance (ESG) strategy and disclosures to meet the needs of our stakeholders moving forward. This additional information below related to our ESG initiatives is supplemental to both the information included in this Corporate Governance section and the information contained in our Annual Report on Form 10-K under the heading “Human Capital.”

Minimizing our carbon footprint is important to our customers, employees, and stockholders. Markforged is committed to protecting the environment by monitoring and managing our business operations to better understand and continuously improve our impact on the environment.

We are also investigating additional ways to prioritize clean energy, reduce water usage, and increase the adoption of environmentally sustainable practices.

We are committed to having a positive impact on the environment. We strive to maximize recycling in both our manufacturing and office facilities. In our manufacturing facilities, we recycle metal, plastic and water used throughout the manufacturing processes.

We are focused on building an inclusive culture and sustaining a diverse workforce through a variety of company initiatives, such as training for employees around diversity and inclusion-related topics designed to create a culture of belonging, as well as active employer sponsored affinity groups. As we continue to grow, we embrace teammates with unique perspectives and backgrounds which allows us to broaden our ability to creatively problem-solve and develop products that work for our customers globally.

Markforged was recognized as one of Boston’s Best Places to Work in 2021 and 2022 by Built In Boston, an online community for Boston startups and tech companies.

We maintain a whistleblower policy that provides for confidential reporting of any suspected policy violations or unethical business conduct on the part of our businesses, employees, officers, directors, or vendors. We provide training to our workforce relating to our Code of Business Conduct and Ethics and anti-corruption and anti-bribery policies.

Our Board of Directors regularly reviews and, when appropriate, revises our corporate governance policies, taking into account internal processes, public company best practices and the corporate governance rules and regulations of the SEC and the NYSE.

We understand the critical importance of managing evolving risks associated with cybersecurity threats. Markforged is committed to protecting the privacy and security of customer information and the integrity of our information technology systems. All employees participate in security awareness training and regular social engineering tests are conducted to reinforce best practices.

We maintain a current ISO 27001:2013 certification (which is issued by independent third party auditors). ISO 27001 is a globally recognized framework for managing Information Technology (IT) security and risk. Our information security risks, policies, and security plans are regularly reviewed by the Markforged Security team and by our cross-functional security steering committee on a quarterly basis.

Any interested party with concerns about our company may report such concerns to the board of directors by submitting a written communication to the attention of the board of directors as a whole or to one or more individual directors by name, at the following address:

You may submit your concern anonymously or confidentially by postal mail. You may also indicate whether you are a stockholder, customer, supplier, or other interested party.

We will forward such communication to each director, and the Chairman of the Board in his or her capacity as representative of the board of directors, to who such communication is addressed to the address specified by each such director and the Chairman of the board of directors. The General Counsel of the Company will review these communications and reserves the right not to forward communications if they are deemed inappropriate, consist of individual grievances or other interests that are personal to the party submitting the communication and could not reasonably be construed to be of concert to stockholders or other constituencies of the Company, solicitations, advertisements, surveys, “junk” mail or mass mailings.

The audit committee oversees the procedures for the receipt, retention, and treatment of complaints received by Markforged regarding accounting, internal accounting controls, or audit matters, including the confidential, anonymous submission by employees of concerns regarding questionable accounting, internal accounting controls or auditing matters. Markforged has also established a telephone number for the reporting of such activity, which is 833-778-1519 (toll free in the United States) or a complaining party may submit a confidential memorandum to the audit committee by sending a letter c/o Markforged Holding Corporation, 60 Tower Road, Waltham, Massachusetts 02451; Attention: Audit Committee Chair.

Our board of directors has adopted a formal Non-Employee Director Compensation Policy. The policy is designed to ensure that the compensation of non-employee directors aligns the directors’ interests with the long-term interests of the stockholders, that the structure of the compensation is simple, transparent and easy for stockholders to understand and that our directors are fairly compensated. Employee directors do not receive additional compensation for their services as directors. This policy is also intended to provide a total compensation package that enables us to attract and retain qualified and experienced individuals to serve as directors.

Under the policy, upon initial election or appointment to the board of directors, new non-employee directors shall receive a restricted stock unit award with a value of $300,000 (which may be pro-rated at the discretion of the board of directors), which vests in equal annual instalments over a three-year period, or the Initial Grant. In addition, upon the date of each annual meeting of stockholders, each non-employee director (other than a director receiving an Initial Grant or who received their Initial Grant within three months prior to the annual meeting) will receive a restricted stock unit award with a value of $150,000, or the Annual Grant, which will vest in full upon the earlier to occur of the first anniversary of the grant date or the date of the next annual meeting of stockholders; provided that any director who received their Initial Grant within three to six months prior to the annual meeting shall be entitled to receive a grant that is 50% of the value of the Annual Grant. Vesting of any equity award will cease if a director resigns from our board of directors or otherwise ceases to serve as a director, unless the board of directors determines that circumstances warrant continuation of vesting. In addition, all such awards are subject to full accelerated vesting upon a sale event of our Company (as defined in the policy).

In addition, the policy provides that each non-employee director is paid an annual retainer of $50,000 for their services. Such cash retainers are paid quarterly, and may be pro-rated based on the number of actual days served by the director during such calendar quarter.

Committee members also receive additional annual retainers. These additional payments for service on a committee are due to the workload and broad-based responsibilities of the committees. These committee retainers are as follows:

Directors will be reimbursed for all reasonable out-of-pocket expenses incurred in attending meetings of the board of directors or any committee.

The table below presents the total compensation for each person who served as a non-employee director during fiscal year 2022. During fiscal year 2022, Mr. Terem, our Chief Executive Officer, was a member of our board of directors, as well as an employee, and received no additional compensation for his services as a director. See the section titled “Executive Compensation” for more information about Mr. Terem’s compensation for fiscal year

The amounts reported represent the aggregate grant date fair value of the restricted stock units awarded to the directors during fiscal year 2022, calculated in accordance with FASB ASC Topic 718. Such grant date fair value does not take into account any estimated forfeitures. The assumptions used in calculating the grant date fair value of the awards reported in this column are set forth in Note 12 to our audited financial statements in in our Annual Report on Form 10-K for the fiscal year ended December 31, 2022. The amounts reported in this column reflect the accounting cost for the restricted stock units and do not correspond to the actual economic value that may be received upon settlement of such restricted stock units or any sale of any of the underlying shares of common stock.

Certain directors and executive officers have adopted written plans, known as Rule 10b5-1 plans, in which they will contract with a broker to buy or sell shares of our common stock on a periodic basis. Under a Rule 10b5-1 plan, a broker executes trades pursuant to parameters established by the director or executive officer when entering into the plan, without further direction from them. The director or executive officer may amend a Rule 10b5-1 plan in some circumstances and may terminate a plan at any time. Our directors and executive officers also may buy or sell additional shares outside of a Rule 10b5-1 plan when they are not in possession of material nonpublic information subject to compliance with the terms of our insider trading policy.

Our named executive officers ("NEO") for the year ended December 31, 2022 include our principal executive officer and our next two most highly compensated executive officers:

The following table presents the compensation awarded to, earned by or paid to each of our named executive officers for the years indicated.

(1)

In accordance with SEC rules, this column reflects the aggregate grant date fair value of the restricted stock units granted during 2022 and 2021, as applicable, computed in accordance with FASB ASC Topic 718. Assumptions used in the calculation of these amounts are included in Note 12 to our financial statements included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2022. The amounts reported in this column reflect the accounting cost for the restricted stock units and does not correspond to the actual economic value that may be received upon settlement of the restricted stock units or any sale of any of the underlying shares of common stock.

(2)

The amounts represent actual bonuses earned by our named executive officers for performance during fiscal years 2022 and 2021, respectively, upon the attainment of one or more pre-established company and individual performance goals established by our board of directors on an annual basis. For Mr. Terem, such amounts also include a quarterly payment of a special milestone bonus, based upon achievement of specified performance goals.

Our board of directors and compensation committee review compensation annually for all employees, including our executive officers. In setting executive base salaries and bonuses and granting equity incentive awards, the compensation committee and board of directors consider compensation for comparable positions in the market, the historical compensation levels of our executive officers, individual performance as compared to our expectations and objectives, internal equity, our desire to motivate our employees to achieve short- and long-term results that are in the best interests of our stockholders, and a long-term commitment to the Company. We target a general competitive position, based on independent third-party benchmark analytics to inform the mix of compensation of base salary, bonus and long-term incentives.

Our compensation committee is primarily responsible for determining the compensation for our executive officers. Our compensation committee typically reviews and discusses management’s proposed compensation with our Chief Executive Officer for all executives other than the Chief Executive Officer. Based on those discussions and its discretion, taking into account the factors noted above, the compensation committee then sets the compensation for each executive officer other than the Chief Executive Officer and recommends the compensation for the Chief Executive Officer to our board of directors for approval. Our board of directors discusses the compensation committee’s recommendation and ultimately approves the compensation of our Chief Executive Officer without members of management present. Our compensation committee has the authority to engage the services of a consulting firm or other outside advisors to assist in its designing of our executive compensation programs and in making compensation decisions. During 2022 and 2021, the compensation committee retained the services of Compensia as its external compensation consultant to advise on executive compensation matters including our overall compensation program design and collection of market data to inform our compensation programs for our executive officers and members of our board of directors. Compensia reports directly to our compensation committee. Our compensation committee assessed its independence consistent with NYSE listing standards and concluded that the engagement of such consultant did not raise any conflict of interest.

We use base salaries to recognize the experience, skills, knowledge and responsibilities required of all our employees, including our named executive officers. Base salaries are reviewed annually, typically in connection with our annual performance review process, and adjusted from time to time to realign salaries with market levels after taking into account individual responsibilities, performance and experience. For the year ended December 31, 2022, the annual base salaries for each of Messrs. Terem, Schwartz and Karp were $500,000, $410,000 and $280,000, respectively.

Mr. Terem is eligible to earn an annual cash incentive bonus which is awarded by our board of directors in its sole discretion. For 2022, each of Messrs. Terem, Schwartz and Karp were eligible to earn a target bonus amount of $600,000, $215,000 and $120,000, respectively. In addition, Mr. Terem is eligible to earn a special milestone bonus of up to $100,000 per year, to be paid on a quarterly basis, based on satisfactory attainment of certain key performance indicators (as determined within the sole discretion of the Board).

Although we do not yet have a formal policy with respect to the grant of equity incentive awards to our named executive officers, we believe that equity grants provide our executives with a strong link to our long-term performance, create an ownership culture and help to align the interests of our executives and our stockholders. In addition, we believe that equity grants promote executive retention because they incentivize our executive officers to remain in our employment during the vesting period. Accordingly, our board of directors periodically reviews the equity incentive compensation of our named executive officers and may grant equity incentive awards to them from time to time.

In 2022, we granted restricted stock units to our named executive officers in the amounts set forth in the “Outstanding Equity Awards at 2022 Fiscal Year End Table” below.

The following table presents information regarding all outstanding equity-based awards held by each of our named executive officers on December 31, 2022.

(1)

Except as otherwise set forth below, each stock option vests over four years, with 25% of the shares subject to each option vesting 12 months after the vesting commencement date, and 1/48 of the shares subject to the option vesting on each monthly anniversary of the vesting commencement date thereafter, in each case, subject to the named executive officer’s continuous service. To the extent that the stock options are assumed and continued in connection with a “sale event,” the stock options will fully accelerate upon the executive’s termination without “cause” or resignation for “good reason” if such termination or resignation occurs within the 12 month period following such sale event.

(3)

This restricted stock unit award vests over five years following the vesting commencement date in twenty equal quarterly installments, subject to the named executive officer's continuous service. To the extent that the restricted stock units are assumed and continued in connection with a “sale event,” the stock options will fully accelerate upon the executive’s termination without “cause” or resignation for “good reason” if such termination or resignation occurs within the 12 month period following such sale event.

(4)

Each restricted stock unit award vests over four years following the vesting commencement date in sixteen equal quarterly installments, subject to the named executive officer’s continuous service. To the extent that the restricted stock units are assumed and continued in connection with a “sale event,” the stock options will fully accelerate upon the executive’s termination without “cause” or resignation for “good reason” if such termination or resignation occurs within the 12 month period following such sale event.

(5)

This restricted stock unit award vests over four years, with 25% of the shares subject to the restricted stock unit award vesting 12 months after the vesting commencement date, and 1/12 of the shares subject to the restricted stock unit award vesting on each quarterly anniversary of the vesting commencement date thereafter, in each case, subject to the named executive officer's continuous service. To the extent that the restricted stock units are assumed and continued in connection with a “sale event,” the stock options will fully accelerate upon the executive’s termination without “cause” or resignation for “good reason” if such termination or resignation occurs within the 12 month period following such sale event.

The material terms of each NEO’s existing employment arrangements are summarized below. In addition, our NEOs have entered into restrictive covenant agreements with us that generally contain 12-month post-employment non-competition and non-solicitation covenants.

On October 21, 2020, we entered into an amended and restated offer letter with Mr. Terem, as amended, pursuant to which we employ Mr. Terem as our President and Chief Executive Officer. The offer letter provides for Mr. Terem’s at-will employment and an annual base salary, a target annual bonus of $200,000, an annual $100,000 special milestone bonus based on attainment of certain key performance indicators, and a $200,000 relocation bonus paid in 2020. In addition, in connection with his relocation to the Boston metropolitan area, the Company will reimburse Mr. Terem for his relocation costs, including commissions for the sale of his home (assumed to be 6% of $1,000,000) and other hotel and travel costs as needed during the gap between permanent housings (such reimbursements to be made on a “grossed-up” basis). The offer letter also provided Mr. Terem with a stock option award, as well as his ability to participate in our employee benefit plans generally.

On January 21, 2021, we entered into an offer letter with Mr. Schwartz, pursuant to which we employ Mr. Schwartz as our Chief Financial Officer. The offer letter provides for Mr. Schwartz’s at-will employment and an annual base salary, a target annual bonus of $100,000, and a $40,000 relocation bonus paid in 2021. The offer letter also provided Mr. Schwartz with a restricted stock unit award, as well as his ability to participate in our employee benefit plans generally.

On October 30, 2020, we entered into an offer letter with Mr. Karp, pursuant to which we employ Mr. Karp as our General Counsel. The offer letter provides for Mr. Karp’s at-will employment and an annual base salary and a target annual bonus of $50,000. The offer letter also provided Mr. Karp with a stock option award, as well as his ability to participate in our employee benefit plans generally.

Executive Severance and Change in Control Plan

On December 31, 2022, we adopted the Executive Severance and Change in Control Plan (the “Severance Plan”) applicable to certain of our executive officers who are notified of their eligibility to participate in the Plan and sign a participation letter (collectively, “Executives”), including our named executive officers. Executives who sign a participation letter to participate in the Plan will

only be eligible to receive severance pay and benefits under this Plan and not under any employment agreement (including the

Under the Plan, in the event of a termination by us without cause (as such term is defined in the Plan) or by the Executive for good reason (as such term is defined in the Plan), in each case more than three (3) months prior to a change in control or more than twelve (12) months following a change in control (as such term is defined in the Plan), the severance benefits for the Executive shall generally consist of the following:

•

coverage of the employer portion of the regular premium for continued group health insurance coverage under COBRA, until the earlier of (A) twelve (12) months for our Chief Executive Officer and six (6) months for all other Executives or (B) the date the Executive becomes eligible for health benefits through another employer or otherwise becomes ineligible for COBRA; and

coverage of the employer portion of the regular premium for continued group health insurance coverage under COBRA, until the earlier of (A) eighteen (18) months for the Chief Executive Officer and twelve (12) months for all other Executives or (B) the date the Executive becomes eligible for health benefits through another employer or otherwise becomes ineligible for COBRA;

Receipt of severance benefits under the Plan is conditioned upon the Executive’s execution of a separation agreement containing, among other provisions, a general release of all claims in favor of us. Payments are designed to comply with Section 409A of the Internal Revenue Code (the “Code”). In addition, if any payment under the Plan would constitute an excess parachute payment within the meaning of Section 280G of the Code, the payments will be reduced to the minimum extent necessary so that no portion of any payment or benefit will constitute an excess parachute payment, provided however, that the reduction will be made only if and to the extent that such reduction would result in an increase in the aggregate payment and benefits to be provided, determined on an after tax basis (taking into account the excise tax imposed pursuant to Section 4999 of the Code, or any successor provision, or any other tax).

We have the right, in our sole discretion, to amend the Plan or to terminate it prospectively, provided that the Plan may not be amended in any manner which is adverse to any Executive without that Executive’s written consent.

The NEOs are eligible to participate in standard welfare benefit plans, including medical, dental, vision, group life and accidental death and dismemberment insurance plans, in each case, on the same basis as all of our other employees. The Company also maintains

a 401(k) plan for the benefit of its eligible employees, including the named executive officers, as discussed in the section below entitled “401(k) plan.”

The Company maintains the MarkForged, Inc. Retirement Plan (the “401(k) Plan”), that provides eligible U.S. employees with an opportunity to save for retirement on a tax advantaged basis. Under the 401(k) Plan, eligible employees may defer eligible compensation subject to applicable annual contribution limits imposed by the Code. The Company’s employees’ pre-tax contributions are allocated to each participant’s individual account and participants are immediately and fully vested in their contributions. The 401(k) Plan is intended to be qualified under Section 401(a) of the Code with the 401(k) Plan’s related trust intended to be tax exempt under Section 501(a) of the Code. As a tax-qualified retirement plan, contributions to the 401(k) Plan and earnings on those contributions are not taxable to the employees until distributed from the 401(k) Plan.

The Company does not maintain or provide any defined benefit pension plans or other supplemental executive retirement plans for the benefit of our named executive officers.

The Company does not have any nonqualified deferred compensation arrangements with our named executive officers.

We have agreed to indemnify our directors and executive officers in certain circumstances. See “Certain Relationships and Related Person Transactions-Markforged Pre-Business Combination – Indemnification of Directors and Officers.”

The following table sets forth information regarding our equity compensation plans as of December 31, 2022.

(1)

Includes shares available under the Markforged Holding Corporation 2021 Stock Option and Incentive Plan (“2021 Plan”), and the Markforged Holding Corporation 2021 Employee Stock Purchase Plan (“2021 ESPP”). The 2021 Plan provides that the number of shares reserved and available for issuance under the plan will automatically increase each January 1, beginning on January 1, 2022, by 5% of the outstanding number of shares of our common stock on the immediately preceding December 31 or such number of shares as determined by the administrator. The ESPP provides that the number of shares reserved and available for issuance under the ESPP will automatically increase each January 1, beginning on January 1, 2022 through January 1, 2031, by at least (i) 4,700,000 shares of our common stock, (ii) 1% of the outstanding number of shares of our common stock on the immediately preceding December 31 or (iii) such number of shares as determined by our administrator.

In addition to the director and executive compensation arrangements, including employment, termination of employment and change in control arrangements, the following is a description of each transition since January 1, 2022, and each currently proposed transaction, in which:

Markforged has entered into indemnification agreements with each of Markforged’s directors and executive officers, the form of which is attached as an exhibit to the registration statement. The indemnification agreements and Markforged’s certificate of incorporation and bylaws require Markforged to indemnify its directors and officers to the fullest extent permitted by Delaware law. Markforged has entered into compensation arrangements, including employment, termination of employment and change in control arrangements and indemnification arrangements, which are, when required, described herein under the sections titled “Certain Relationships and Related Party Transactions ” and “Corporate Governance—Director Compensation”.

Our audit committee has the primary responsibility for reviewing and approving or disapproving “related party transactions,” which are transactions between us and related persons in which the aggregate amount involved exceeds or may be expected to exceed $120,000 and in which a related person has or will have a direct or indirect material interest. The written charter of our audit committee provides that our audit committee shall review and approve in advance any related party transaction.

Our board of directors adopted a written related person transaction policy providing that transactions with our directors, executive officers and holders of five percent or more of our voting securities and their affiliates, each a related person, must be approved by the audit committee. This policy became effective on July 14, 2021. Pursuant to this policy, the audit committee has the primary responsibility for reviewing and approving or disapproving “related person transactions,” which are transactions between us and related persons and in which a related person has or will have a direct or indirect material interest.

Pursuant to this policy, the material facts as to the related person’s relationship or interest in the transaction are disclosed to our audit committee prior to their consideration of such transaction. The audit committee will consider, among other factors that it deems appropriate, whether the transaction is on terms no less favorable to us than terms generally available in a transaction with an unaffiliated third-party under the same or similar circumstances and the extent of the related person’s interest in the transaction.

The following table sets forth information, to the extent known by us or ascertainable from public filings, with respect to the beneficial ownership of our common stock as of April 21, 2023 by:

The column entitled “Shares Beneficially Owned” is based on a total of 196,323,235 shares of our common stock outstanding as of April 21, 2023 (the “Determination Date”).

Beneficial ownership is determined in accordance with the rules and regulations of the SEC and includes voting or investment power with respect to our common stock. Shares of our common stock subject to options that are currently exercisable or exercisable within 60 days of April 21, 2023 are considered outstanding and beneficially owned by the person holding the options for the purpose of calculating the percentage ownership of that person but not for the purpose of calculating the percentage ownership of any other person. Except as otherwise noted, the persons and entities in this table have sole voting and investing power with respect to all of the shares of our common stock beneficially owned by them, subject to community property laws, where applicable. Except as otherwise indicated in the table below, addresses of named beneficial owners is c/o Markforged Holding Corporation, 60 Tower Road, Waltham, Massachusetts 02451.

In computing the number of shares of Common Stock beneficially owned by a selling stockholder and the percentage ownership of that person, we deemed to be outstanding all shares of Common Stock subject to awards under the Plans, including options and restricted stock units, held by that person that are vested or exercisable as of the Determination Date or that will become vested or exercisable within 60 days after the Determination Date.

(2)

Percentages are based on the 196,323,235 shares of Common Stock issued and outstanding as of the Determination Date. In computing the percentage ownership of each Selling Stockholder, we deemed to be outstanding all shares of Common Stock then subject to awards under the Plans, including options and restricted stock units, held by that person that are vested or exercisable as of the Determination Date or that would become vested or exercisable within 60 days after the Determination Date, but we did not deem these shares of Common Stock outstanding for the purpose of computing the percentage ownership of any other Selling Stockholder.

The audit committee is appointed by the board of directors to assist the board of directors in fulfilling its oversight responsibilities with respect to (1) the integrity of Markforged’s financial statements and financial reporting process and systems of internal controls regarding finance, accounting, and compliance with legal and regulatory requirements, (2) the qualifications, independence, and performance of Markforged’s independent registered public accounting firm, (3) the performance of Markforged’s internal audit function, if any, and (4) other matters as set forth in the charter of the audit committee approved by the board of directors.

Management is responsible for the preparation of Markforged’s financial statements and the financial reporting process, including its system of internal control over financial reporting and its disclosure controls and procedures. The independent registered public accounting firm is responsible for performing an audit of Markforged’s financial statements in accordance with the standards of the Public Company Accounting Oversight Board (PCAOB) and issuing a report thereon. The audit committee’s responsibility is to monitor and oversee these processes.

In connection with these responsibilities, the audit committee reviewed and discussed with management and the independent registered public accounting firm the audited consolidated financial statements of Markforged for the fiscal year ended December 31, 2022. The audit committee also discussed with the independent registered public accounting firm the matters required to be discussed by the PCAOB’s Auditing Standard No. 1301, Communication with Audit Committees. In addition, the audit committee received written communication from the independent registered public accounting firm confirming their independence as required by the applicable requirements of the PCAOB and has discussed with the independent registered public accounting firm their independence.

Based on the reviews and discussions referred to above, the audit committee recommended to the board of directors that the audited consolidated financial statements of Markforged be included in Markforged’s Annual Report on Form 10-K for the fiscal year ended December 31, 2022, that was filed with the SEC. The information contained in this report shall not be deemed to be (1) “soliciting material,” (2) “filed” with the SEC, (3) subject to Regulations 14A or 14C of the Exchange Act, or (4) subject to the liabilities of Section 18 of the Exchange Act. This report shall not be deemed incorporated by reference into any of our other filings under the Exchange Act or the Securities Act, except to the extent that we specifically incorporate it by reference into such filing.

Some banks, brokers and other nominee record holders may be participating in the practice of “householding” proxy statements and annual reports. This means that only one copy of our documents, including the annual report to stockholders and proxy statement, may have been sent to multiple stockholders in your household. We will promptly deliver a separate copy of either document to you upon written or oral request to Markforged Holding Corporation, 60 Tower Road, Waltham, Massachusetts 02451, Attention: Corporate Secretary, telephone: (866) 496-1805. If you want to receive separate copies of the proxy statement or annual report to stockholders in the future, or if you are receiving multiple copies and would like to receive only one copy per household, you should contact your bank, broker or other nominee record holder, or you may contact us at the above address and phone number.

Our bylaws provide that, for nominations of persons for election to our board of directors or other proposals to be considered at an annual meeting of our stockholders, a stockholder must give written notice to Markforged Holding Corporation, 60 Tower Road, Waltham, Massachusetts 02451, Attention: Corporate Secretary, not later than the close of business 90 days, nor earlier than the close of business 120 days, prior to the first anniversary of the date of the preceding year’s annual meeting. However, our bylaws also provide that in the event the date of the annual meeting is more than 30 days before or more than 60 days after such anniversary date, notice must be delivered not later than the close of business on the later of the 90th day prior to such annual meeting or the 10th day following the day on which public announcement of the date of such meeting is first made. Any nomination must include all information relating to the nominee that is required to be disclosed in solicitations of proxies for election of directors in election contests or is otherwise required under Regulation 14A of the Exchange Act, the person’s written consent to be named in the proxy statement and to serve as a director if elected and such information as we might reasonably require to determine the eligibility of the person to serve as a director. As to other business, the notice must include a brief description of the business desired to be brought before the meeting, the reasons for conducting such business at the meeting, and any material interest of such stockholder (and the beneficial owner) in the proposal. The proposal must be a proper subject for stockholder action. In addition, to make a nomination or proposal, the stockholder must be of record at the time the notice is made and must provide certain information regarding itself (and the beneficial owner), including the name and address, as they appear on our books, of the stockholder proposing such business, the number of shares of our capital stock which are, directly or indirectly, owned beneficially or of record by the stockholder proposing such business or its affiliates or associates (as defined in Rule 12b-2 promulgated under the Exchange Act) and certain additional information.

The advance notice requirements for the Annual Meeting are as follows: a stockholder’s notice shall be timely if delivered to our Secretary prior to the meeting at which the action is to be taken. Generally, to be timely, notice must be received at our principal executive offices not less than 90 days nor more than 120 days prior to the first anniversary of the date of the annual meeting for the preceding year. Our bylaws specify the requirements as to form and content of all stockholders’ notices. These requirements may preclude stockholders from bringing matters before the stockholders at an annual or special meeting.
