Proxy Statement and Notice of 2026 Annual Meeting

Annuol Meeting of Stockhoiders

April 29, 2026

Dear Fellow Stockholders

2025 was a truly transformative and record-setting year for Xometry, clearly validating the success and inherent operating leverage of our global AI-native marketplace. We are not just digitizing the vast, complex, and fragmented custom manufacturing market; we are a leader in its inevitable evolution.

We are proud to report that in 2025 Xometry reached major milestones on our path to sustained free cash flow profitability.

Operating Leverage: We achieved full year Adjusted EBITDA1 of $18.5 million with profitability increasing as the year progressed, demonstrating the strength of our strategic execution and the operating leverage built into our model as operating expenses grew at a substantially lower rate than revenue.

These results are a direct consequence of marketplace innovation and relentless execution by our teams.

We expect strong secular growth to continue in 2026 and beyond, driven by three key initiatives designed to deepen our competitive advantage and capture further market share.

Our success is fundamentally underpinned by the proprietary data generated exclusively within the Xometry marketplace.

This is a critical competitive moat: unlike models built on publicly available data, our data pipelines and AI models use inputs that only our customers, suppliers, and Xometry have access to. This powerful, unique data is generated across every marketplace interaction, including:

Customer purchase intent, Design for Manufacturing ("DFM") analysis, and quoting activity. Order execution, supplier performance, pricing outcomes, and part quality.

Supply chain lead time for manufacturing and logistics.

1 Adjusted EBITDA is a non-GAAP measure. For further information regarding Adjusted EBITDA, including the limitations of the use of Adjusted EBITDA and a reconciliation of Adjusted EBITDA to net loss, the most directly comparable financial measure stated in accordance with GAAP, see "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations-Non-GAAP Financial Measures" in our Annual Report on Form 10-K for the fiscal year ended December 31, 2025.

This input data is constantly augmented with structured signals generated during the real-world order-to-part manufacturing lifecycle. This ever-growing, closed-loop system is what drives our superior pricing, sourcing, and gross margin expansion, ensuring our competitive advantage grows stronger with every transaction.

The strength of Xometry is further demonstrated by our planned leadership transition, announced in February 2026.

Effective July 1, 2026, I will transition to Executive Chair of the Board, and Sanjeev Singh Sahni, our current President, will become Chief Executive Officer

This is a deliberate, Board-aligned succession process that secures the ideal leader for our next chapter of growth. Sanjeev has been my close partner, holding the operational mandate for our global teams and proving instrumental in Xometry's accelerated revenue growth, expanding Adjusted EBITDA profitability, and deepening our advanced technology and AI capabilities. Sanjeev's proven track record of driving global growth, innovation, and scale with large global marketplaces makes him the definitive choice to lead our next stage of innovation and profitable expansion.

To foster a smooth transition while continuing to contribute my own expertise and insight where they are most valuable, I will remain closely involved as Executive Chair, focusing on strategic growth initiatives and key corporate partnerships.

We stand at a pivotal juncture in manufacturing, defined by accelerating digital transformation, the need for resilient supply chains (including reshoring), and rapid AI-driven innovation. This new era demands robust digital workflows-precisely what Xometry's AI-native marketplace delivers.

Our platform replaces manual, legacy processes by digitizing how custom manufacturing is priced, sourced, and fulfilled.

The proprietary data generated by our growing network of buyers and suppliers continues to create powerful and increasing network effects

We are confident that Xometry is positioned not just to participate in this market shift, but to lead it. We look forward to continuing to create significant value for our customers, partners, and you, our stockholders, in the years ahead.

We are pleased to invite you to attend the 2026 Annual Meeting of Stockholders of Xometry, Inc., a Delaware corporation ("Xometry") to be held virtually on June 16, 2026 at 11:00 a.m., Eastern Time. To provide expanded access from locations around the world and to lower costs, we are continuing with a virtual format for our 2026 Annual Meeting, which will be held solely online via live webcast. There will not be a physical location for the Annual Meeting, and you will not be able to attend the Annual Meeting in person.

You will be able to attend the Annual Meeting, ask your questions and vote your shares during the meeting by visiting https://www.virtualshareholdermeeting.com/XMTR2026 and entering the control number located on the Notice of Internet Availability of Proxy Materials for the 2026 Annual Meeting of Stockholders, your proxy card or voting instruction form. Additional details regarding access to the Annual Meeting and the business to be conducted at the Annual Meeting are described in the accompanying Notice of 2026 Annual Meeting of Stockholders and proxy statement.

We have elected to provide access to our proxy materials over the Internet under the U.S. Securities and Exchange Commission's "notice and access" rules. As a result, we are mailing to our stockholders a Notice of Internet Availability of Proxy Materials instead of paper copies of the proxy statement and our 2025 Annual Report. The notice contains instructions on how to access those documents over the Internet. The Notice of Internet Availability of Proxy Materials also contains instructions on how stockholders can receive a paper copy of our proxy materials, including the proxy statement, our 2025 Annual Report and a form of proxy card or voting instruction form. We believe that providing our proxy materials over the Internet increases the ability of our stockholders to connect with the information they need, while reducing the environmental impact and cost of our Annual Meeting.

Your vote is important. Whether or not you plan to attend the Annual Meeting, we hope you will vote as soon as possible.

You may vote over the Internet, by telephone or, if you receive a paper proxy card by mail, by completing and returning the proxy card or voting instruction form mailed to you. Please carefully review the instructions on each of your voting options described in this proxy statement, as well as in the Notice of Internet Availability of Proxy Materials you received in the mail.

On behalf of the Xometry Board of Directors and employees, we thank you for your continued support and look forward to speaking with you at the Annual Meeting.

Sincerely,

Randy Altschuler

Pursuant to rules adopted by the Securities and Exchange Commission (the "SEC"), we have elected to provide access to our Proxy Materials (as defined below) over the Internet.

(the "Board") is soliciting your proxy to vote at the 2026 Annual Meeting of Stockholders (the "Annual Meeting") of Xometry, Inc., including at any adjournments or postponements thereof, to be held on Tuesday, June 16, 2026 at 11:00 a.m., Eastern Time. The Annual Meeting can be accessed by visiting https://www.virtualshareholdermeeting.com/XMTR2026

The Notice of 2026 Annual Meeting of Stockholders ("Notice of Annual Meeting"), this proxy statement, the proxy card or voting instruction form, and our Annual Report on Form 10-K for the fiscal year ended December 31, 2025 (the "Annual Report" and, together with the proxy statement and proxy card or voting instruction form, the "Proxy Materials") are available to stockholders on the Internet

The Board has fixed the record date for the Annual Meeting as of the close of business on April 20, 2026 (the "Record Date").

We will be hosting the Annual Meeting via live webcast only. You are entitled to attend the Annual Meeting if you were a stockholder as of the close of business on the Record Date, or if you hold a valid proxy for the meeting. There will not be a physical location for the Annual Meeting, and you will not be able to attend the Annual Meeting in person.

The Annual Meeting will begin promptly at 11:00 a.m., Eastern Time, on Tuesday, June 16, 2026.

Only stockholders of record as of the Record Date may submit questions or comments that may be addressed during the Annual Meeting. If you would like to submit a question, you may do so by going to https://www.virtualshareholdermeeting.com/XMTR2026 and entering the 16-digit control number included on your Notice of Internet Availability, on your proxy card or on the instructions that accompanied your proxy materials, as applicable. If your shares are held by a broker, use the control number provided by your broker found on your notice or voting instruction form.

In accordance with the rules of conduct, we ask that you limit your questions to questions that are relevant to the Annual Meeting or our business and that such questions are respectful of your fellow stockholders and meeting participants. Questions and answers may be grouped by topic, and substantially similar questions may be grouped and answered once. In addition, questions may be ruled out of order if they are, among other things, irrelevant to our business, related to pending or threatened litigation, disorderly, repetitious of statements already made, or in furtherance of the stockholder's own personal, political or business interests

A list of stockholders entitled to vote at the meeting will be available for examination during normal business hours by any stockholder for any purpose germane to the meeting for the ten days ending the day prior to the meeting at our offices. Please email legal@xometry.com to arrange for an in-person examination.

Only stockholders of record at the close of business on the Record Date will be entitled to vote online during the Annual Meeting. On the Record Date, there were 51,123,487 shares of Class A common stock and 1,475,311 shares of Class B common stock outstanding and entitled to vote.

Stockholder of Record: Shares Registered in Your Name

If, on the Record Date, your shares were registered directly in your name with our transfer agent, Computershare Trust Company, N.A. ("Computershare"), then you are a stockholder of record. As a stockholder of record, you may vote online during the meeting by going to https://www.virtualshareholdermeeting.com/XMTR2026 and entering the 16-digit control number included on your Notice of Internet Availability, on your proxy card or on the instructions that accompanied your proxy materials, as applicable.

Whether or not you plan to attend the Annual Meeting, we urge you to vote by proxy to ensure your vote is counted.

Beneficial Owner: Shares Registered in the Name of a Broker, Bank or Similar Organization

If, on the Record Date, your shares were held, not in your name, but rather in an account at a brokerage firm, bank, dealer or other similar organization, then you are the beneficial owner of shares held in "street name" and the Notice of Internet Availability should be forwarded to you by that organization. The organization holding your account is considered to be the stockholder of record for purposes of voting at the Annual Meeting. As a beneficial owner, you have the right to direct your broker, bank or other agent regarding how to vote the shares in your account. You are also invited to attend the Annual Meeting. However, since you are not the stockholder of record, you must follow the instructions provided by your brokerage firm, bank or other similar organization for your bank, broker or other stockholder of record to vote your shares per your instructions. Alternatively, many brokers and banks provide the means to grant proxies or otherwise instruct them to vote your shares by telephone and via the internet, including by providing you with a control number via email or on your notice or your voting instruction form. If your shares are held in an account with a broker, bank or other stockholder of record providing such a service, you may instruct them to vote your shares by telephone (by calling the number provided in the Proxy Materials) or over the internet as instructed by your broker, bank or other stockholder of record. If you did not receive a control number via email or on your notice or voting instruction form and you wish to vote prior to or at the virtual Annual Meeting, you must follow the instructions from your broker, bank or other stockholder of record, including any requirement to obtain a valid legal proxy. Many brokers, banks and other stockholders of record allow a beneficial owner to obtain a valid legal proxy either online or by mail, and we recommend you contact your broker, bank or other stockholder of record to do so. You may not vote your shares online during the meeting unless you request and obtain a valid proxy from your broker or other agent, as required.

There are three matters scheduled for a vote

Proposal 1: Election of the Board of Directors' three nominees for Class II directors, Roy Azevedo, Fabio Rosati and Katharine Weymouth, each to hold office until our Annual Meeting of Stockholders in 2029;

Proposal 2: Advisory approval of the compensation of our named executive officers, as disclosed in this proxy statement in accordance with SEC rules;

Proposal 3: Ratification of the selection of Deloitte & Touche LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2026.

The Board knows of no other matters that will be presented for consideration at the Annual Meeting. If any other matters are properly brought before the meeting, the proxies will vote as recommended by the Board or, if no recommendation is given, will vote on those matters in accordance with their best judgment.

For Proposal 1, you may either vote "For" the nominee to the Board or you may "Withhold" your vote for the nominee to the Board. For each of the other matters to be voted on, you may vote "For" or "Against" or abstain from voting.

The procedures for voting are fairly simple:

Stockholder of Record: Shares Registered in Your Name

If you are a stockholder of record and your shares are registered directly in your name, you may vote (i) online during the Annual Meeting or (ii) in advance of the Annual Meeting by proxy through the Internet, by telephone or by using a proxy card that you may request or that we may elect to deliver at a later time. Whether or not you plan to attend the Annual Meeting, we urge you to vote by proxy to ensure your vote is counted. You may still attend the Annual Meeting and vote online even if you have already voted by proxy.

Online during the Annual Meeting. You will be able to attend the Annual Meeting online and vote during the meeting by visiting www.virtualshareholdermeeting.com/XMTR2026 and entering the control number included on your Notice of Internet Availability, on your proxy card or on the instructions that accompanied your proxy materials, as applicable.

By Internet in advance of the Annual Meeting. Go to www.proxyvote.com to complete an electronic proxy card. You will be asked to provide the company number and control number from the enclosed proxy card.

By Telephone in advance of the Annual Meeting. Call 1-800-690-6903 toll-free from the U.S., U.S. territories and Canada, and follow the instructions on the Notice of Internet Availability. You will be asked to provide your control number from the Notice of Internet Availability.

By Proxy Card in advance of the Annual Meeting. Complete, sign and mail the proxy card that may be delivered and return it promptly in the envelope provided or return it to Vote Processing, c/o Broadridge, 51 Mercedes Way, Edgewood, NY 11717. Proxy cards submitted by mail must be received by 5:00 p.m., Eastern Time, on June 15, 2026 in order to be voted at the Annual Meeting.

Internet and telephone voting facilities for stockholders of record will close at 11:59 p.m. Eastern Time, on June 15, 2026.

Beneficial Owner: Shares Registered in the Name of Broker or Bank

If your shares of common stock are held in street name (i.e., held for your account by a broker, bank or other nominee), you should have received a notice containing voting instructions from that organization rather than from us. You should follow the instructions in the notice to ensure your vote is counted. Alternatively, many brokers and banks provide the means to grant proxies or otherwise instruct them to vote your shares by telephone and via the internet, including by providing you with a control number via email or on notice or your voting instruction form. If your shares are held in an account with a broker, bank or other stockholder of record providing such a service, you may instruct them to vote your shares by telephone (by calling the number provided in the Proxy Materials) or over the internet as instructed by your broker, bank or other stockholder of record. If you did not receive a control number via email or on your notice or voting instruction form, and you wish to vote prior to or at the virtual Annual Meeting, you must follow the instructions from your broker, bank or other stockholder of record, including any requirement to obtain your control number. Many brokers, banks and other stockholders of record allow a beneficial owner to obtain their control number either online or by mail, and we recommend that you contact your broker, bank or other stockholder of record to do so.

Each holder of shares of our Class A common stock will have one vote per share of Class A common stock held as of the Record Date, and each holder of shares of our Class B common stock will have twenty votes per share of Class B common stock held as of the Record Date. The holders of the shares of our Class A common stock and Class B common stock will vote as a single class on all matters described in this proxy statement for which your vote is being solicited.

The Board recommends a vote

Proposal 1: FOR the election of the Board's three nominees for Class II directors named in this proxy statement; Proposal 2: FOR the approval of the advisory vote on the compensation of our named executive officers; and

Proposal 3: FOR the ratification of the selection of Deloitte & Touche LLP as our independent registered public accounting firm for the year ending December 31, 2026.

If you are a stockholder of record and do not vote by completing your proxy card, by telephone, through the Internet or online during the Annual Meeting, your shares will not be voted.

If you return a signed and dated proxy card or otherwise vote without marking voting selections, your shares will be voted, as applicable, "FOR" the election of the three nominees for director named in this proxy statement, "FOR" the advisory approval of the compensation of our named executive officers, and "FOR" the ratification of the selection of Deloitte & Touche LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2026. If any other matter is properly presented at the meeting, your proxyholder (one of the individuals named on your proxy card) will vote your shares using such proxyholder's best judgment.

If you are a beneficial owner of shares held in street name and you do not instruct your broker, bank or other agent how to vote your shares, the question of whether your broker or nominee will still be able to vote your shares depends on whether, pursuant to stock exchange rules, the particular proposal is deemed to be a "routine" matter. Brokers and nominees can use their discretion to vote "uninstructed" shares with respect to matters that are considered to be "routine," but not with respect to "non-routine" matters Under applicable rules and interpretations, "non-routine" matters are matters that may substantially affect the rights or privileges of stockholders, such as mergers, stockholder proposals, elections of directors (even if not contested), executive compensation, and certain corporate governance proposals, even if management-supported. In this regard, Proposals 1 and 2 are considered to be "non-routine" under applicable rules, meaning your broker or nominee may not vote your shares on Proposals 1 or 2 without your instructions. Such an event would result in a "broker non-vote" and these shares will not be counted as having been voted for such proposals. However, Proposal 3 is considered to be a "routine" matter, meaning that if you do not return voting instructions to your broker or nominee by its deadline, your broker or nominee may vote your shares in its discretion on Proposal 3.

If you are a beneficial owner of shares held in street name, to ensure your shares are voted in the way you would prefer, you must provide voting instructions to your broker, bank or other agent by the deadline provided in the materials you receive from your broker, bank or other nominee.

If you receive more than one Notice of Internet Availability, your shares may be registered in more than one name or in different accounts. Please follow the voting instructions on each notice to ensure that all of your shares are voted.

Stockholder of Record: Shares Registered in Your Name

Yes. If you are the stockholder of record for your shares, you may revoke your proxy at any time before the final vote at the Annual Meeting in one of the following ways:

by submitting another properly completed proxy with a later date;

by transmitting a subsequent vote over the Internet or by telephone prior to the start of the Annual Meeting;

by sending a timely written notice to our Secretary in writing at Xometry, Inc., 6116 Executive Boulevard, Suite 800, North Bethesda, Maryland 20852 received by the close of business on the business day one week preceding the date of the Annual Meeting that you are revoking your proxy; or

by attending the Annual Meeting via the live webcast and voting your shares online by clicking on the "Cast Your Vote" link in the meeting center at https://www.virtualshareholdermeeting.com/XMTR2026. Simply attending the Annual Meeting via the live webcast will not, by itself, revoke your proxy.

Your last vote, whether prior to or at the Annual Meeting, is the vote that we will count.

Beneficial Owner: Shares Registered in the Name of a Broker, Bank or Similar Organization

If your shares are held in street name, you must contact your broker or nominee for instructions as to how to change your vote.

Your personal attendance at the Annual Meeting does not revoke your proxy. Your last vote, whether prior to or at the Annual Meeting, is the vote that we will count.

A quorum of stockholders is necessary to hold a valid meeting. The presence, in person, by remote communication, if applicable, or by proxy duly authorized, of the holders of a majority of the voting power of the outstanding shares entitled to vote at the Annual Meeting shall constitute a quorum for the transaction of business. The inspector(s) of election appointed for the Annual Meeting will determine whether or not a quorum is present.

In the absence of a quorum, any meeting of stockholders may be adjourned, from time to time, either by the chairperson of the meeting or by vote of the holders of a majority of the voting power of the shares represented thereat and entitled to vote thereon, but no other business shall be transacted at such meeting.

"

"

Votes will be counted by the inspector of election appointed for the Annual Meeting, who will separately count: (1) with respect to Proposal 1, votes "FOR," WITHHOLD" and broker non-votes, (2) with respect to Proposal 2, votes "FOR," AGAINST," abstentions and broker non-votes, and (3) with respect to Proposal 3, votes "FOR," AGAINST" and abstentions Abstentions will not be counted towards the vote total and have no effect on Proposals 2 and 3. Broker non-votes have no effect and will not be counted towards the vote total for Proposals 1 and 2.

As discussed above, broker non-votes occur when your broker submits a proxy for the meeting with respect to "routine" matters but does not vote on "non-routine" matters because you did not provide voting instructions on those matters. Proposals 1 and 2 are considered to be "non-routine," and we therefore expect broker non-votes to exist only in connection with these proposals.

As a reminder, if you are a beneficial owner of shares held in street name, in order to ensure your shares are voted in the way you would prefer, you must provide voting instructions to your broker, bank or other agent by the deadline provided in the materials you receive from your broker, bank or other agent.

The following table summarizes the minimum vote needed to approve each proposal and the effect of abstentions and broker non-votes

1. Election of Director

Directors are elected by a plurality of the votes of

the holders of shares present in person, by remote communication, if applicable, or represented by proxy duly authorized at the meeting and entitled to vote on the election of directors. You may not vote your shares cumulatively for the election of directors. The three nominees receiving the most FOR votes will be elected

No effect

No effect

2. Advisory Vote to Approve Compensation of Our Named Executive Officers

This proposal, commonly referred to as the "say-

n-pay" vote, must receive FOR votes from the holders of a majority of the voting power of the shares present in person, by remote communication, if applicable, or represented by proxy duly authorized at the meeting and voting affirmatively or negatively (excluding abstentions and broker non-votes) on such matter.

No effect No effect

3. Ratification of the Selection of Deloitte

& Touche LLP as Our Independent Registered Public Accounting Firm

This proposal must receive FOR votes from the

holders of a majority of the voting power of the shares present in person, by remote communication, if applicable, or represented by proxy duly authorized at the meeting and voting affirmatively or negatively (excluding abstentions and broker non-votes) on such matter.

No effect

Not applicable

We will announce preliminary voting results at our Annual Meeting. We will publish final voting results in a Current Report on Form 8-K that we will file with the SEC within four business days after the Annual Meeting. If final voting results are not available at that time, we will disclose the preliminary results in the Current Report on Form 8-K and, within four business days after the final voting results are known to us, file an amended Current Report on Form 8-K to disclose the final voting results.

We will pay the entire cost of soliciting proxies. In addition to these Proxy Materials, our directors and employees may also solicit proxies in person, by telephone or by other means of communication. Directors and employees will not be paid any additional compensation for soliciting proxies. We will also reimburse brokers, banks, custodians, other nominees and fiduciaries for forwarding these materials to their principals to obtain the authorization for the execution of proxies.

If you are the stockholder of record for your shares, please call Shawn Milne, our Vice President of Investor Relations, at 240.335.8132 or email shawn.milne@xometry.com. If your shares are held in street name, please contact the telephone number provided on your voting instruction form or contact your broker or nominee holder directly.

Our Board is currently composed of six directors and is divided into three classes. Each class consists, as nearly as possible, of one-third of the total number of directors and has a three-year term. At each annual meeting of stockholders, the successors to directors whose terms then expire will be elected to serve from the time of election until the third annual meeting following the election

Our directors are divided into three classes as follows

Class II directors: Roy Azevedo, Fabio Rosati and Katharine Weymouth, whose terms will expire at the upcoming Annual Meeting;

Class III directors: Ranjana Clark and Emily Rollins, whose terms will expire at the Annual Meeting of Stockholders to be held in 2027; and

Class I director: Randolph Altschuler, whose term will expire at the Annual Meeting of Stockholders to be held in 2028.

Messrs. Azevedo and Rosati and Ms. Weymouth each currently serve as members of our Board. Mr. Rosati and Ms. Weymouth were previously elected to the Board by the stockholders in 2023. There are no arrangements or understandings between us and any nominee for directorship, pursuant to which such person was selected as a nominee. Messrs. Azevedo and Rosati and Ms.

Weymouth have been nominated for reelection to serve as Class II directors, based in part on the recommendation of the Nominating and Corporate Governance Committee, and have agreed to be named in this proxy statement and stand for reelection at the Annual Meeting. If any nominee becomes unavailable for election as a result of an unexpected occurrence, your shares will be voted for the election of a substitute nominee proposed by our Board. The Board has no reason to believe that any nominee would prove unable to serve if elected. If elected at the Annual Meeting, Messrs. Azevedo and Rosati and Ms. Weymouth would serve until the Annual Meeting of Stockholders to be held in 2029 and until his or her successor has been duly elected, or if sooner, until his or her death, resignation or removal.

On February 24, 2026, the Company announced certain changes to its executive team and Board that would be effective as of July 1, 2026, namely (1) the appointment of Sanjeev Singh Sahni, currently the Company's President, as the Company's Chief Executive Officer, and to the Board as a Class I director; (2) the resignation of Mr. Altschuler as the Company's Chief Executive Officer and the appointment of Mr. Altschuler as the Executive Chair of the Board for an indefinite term; and (3) the appointment of Mr. Rosati, currently the Chair of the Board, as the Board's lead independent director. With the appointment of Mr. Altschuler to Executive Chair of the Board, the Board determined that Mr. Rosati will no longer serve as Chair of the Board. Mr. Altschuler will remain an employee of the Company. The Board approved an increase in the size of the Board from six to seven members to allow for the appointment of Mr. Singh Sahni to the Board, effective on July 1, 2026.

Any additional directorships resulting from an increase in the number of directors will be distributed among the three classes so that, as nearly as possible, each class will consist of one-third of the directors. Vacancies on the Board may be filled only by persons elected by a majority of the remaining directors. A director elected by the Board to fill a vacancy in a class, including vacancies created by an increase in the number of directors, shall serve for the remainder of the full term of that class and until the director's successor is duly elected and qualified. The division of our board of directors into three classes with staggered three-year terms may delay or prevent a change of our management or a change in control of our company.

The biographies below under "Information Regarding Director Nominees and Current Directors" include information, as of the date of this proxy statement, regarding the specific and particular experience, qualifications, attributes or skills of each director nominee that led the Nominating and Corporate Governance Committee to believe that the nominee should continue to serve on the Board. However, each of the members of the Nominating and Corporate Governance Committee may have a variety of reasons why a particular person would be an appropriate nominee for the Board, and these views may differ from the views of other members.

The following table sets forth, for the Class II nominees and our other directors who will continue in office after the Annual Meeting, their ages and position or office held with us as of the date of this proxy statement.

Set forth below is biographical information for the director nominees and each person whose term of office as a director will continue after the Annual Meeting. This includes information regarding each director's experience, qualifications, attributes or skills that led the Board to recommend them for board service.

As required under The Nasdaq Stock Market ("Nasdaq") listing standards, a majority of the members of a listed company's Board must qualify as "independent," as affirmatively determined by the Board. The Board consults with our counsel to ensure that the Board's determinations are consistent with relevant securities and other laws and regulations regarding the definition of "independent," including those set forth in pertinent listing standards of Nasdaq, as in effect from time to time.

Based on information provided by each director concerning such director's background, employment, affiliations, all relevant identified transactions or relationships between each director or any of such director's family members, and Xometry, our senior management and our independent auditors, the Board has affirmatively determined that Mses. Clark, Rollins and Weymouth and Messrs. Azevedo and Rosati are "independent" in accordance with the Nasdaq listing standards applicable to boards of directors in general. Ms. Bial, who left our board in June 2025, was "independent" under the Nasdaq listing standards during the portion of 2025 for which she served on the Board. The Board also determined that each member of our Audit, Compensation and Nominating and Corporate Governance Committees satisfies the independence standards for such committees established by the SEC and the Nasdaq listing standards, as applicable.

In making this determination, the Board found that none of these current or former directors has or had any relationships that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director, taking into account the current and prior relationships that each non-employee director has with us and all other facts and circumstances our Board deemed relevant in determining their independence, including the beneficial ownership of our shares by each non-employee director and the transactions described in the section titled "Transactions with Related Persons." Mr. Altschuler, by virtue of his position as Chief Executive Officer and status as our co-founder, is not "independent" under the Nasdaq listing standards.

Our Corporate Governance Guidelines specify that the Board will select our Chief Executive Officer and chairperson of the Board in the manner that it determines to be in the best interests of our stockholders and in accordance with any stockholder agreements. The Board does not believe there should be a fixed rule regarding the positions of Chief Executive Officer and chairperson being held by different individuals, or whether the chairperson should be a Xometry employee or should be elected from among the non-employee directors. The needs of Xometry and the individuals available to assume these roles may require different outcomes at different times, and the Board believes that retaining flexibility in these decisions is in the best interests of Xometry.

At this time, the Board has an independent chair, Mr. Rosati, who has authority, among other things, to call and preside over Board meetings, including meetings of the independent directors, to set meeting agendas and to determine materials to be distributed to the Board. Accordingly, the Board chair has substantial ability to shape the work of the Board.

As described above, effective as of July 1, 2026, Mr. Altschuler will resign as Chief Executive Officer and be appointed as Executive Chair of the Board for an indefinite term, and Mr. Rosati will be appointed as the Board's lead independent director. The Board believes that the Company will benefit from Mr. Altschuler's extensive knowledge of and longstanding experience with our business, operations and industry. The Board believes that Mr. Altschuler is well positioned to provide leadership to the Board, to work with Mr. Singh Sahni as Chief Executive Officer to set the Board's agenda, to facilitate communications among our directors and between the Board and senior management, and to ensure that our directors receive the information they need to perform their responsibilities. At the same time, the Board believes that the separation of the positions of Executive Chair and Chief Executive Officer will reinforce the Board's oversight of our business and affairs and enable Mr. Singh Sahni to focus on the day-to-day management of the Company.

The Board believes the appointment of Mr. Rosati as lead independent director will help reinforce the independence of the Board as a whole. The position of lead independent director has been structured to serve as an effective balance to the Executive Chair: the lead independent director is empowered to, among other duties and responsibilities, preside over Board meetings in the absence of the Board Chair, act as liaison between the Board Chair and the independent directors, preside over meetings of the independent directors, and consult with the Board Chair in planning and setting schedules and agendas for Board meetings. As a result, the Board believes that the lead independent director can help ensure the effective independent functioning of the Board in its oversight responsibilities and is better positioned to build a consensus among directors and to serve as a conduit between the other independent directors and the Board Chair.

One of the Board's key functions is informed oversight of our risk management process. The Board does not have a standing risk management committee, but rather administers this oversight function directly through the Board as a whole, as well as through various Board standing committees that address risks inherent in their respective areas of oversight. In particular, our Board is

responsible for monitoring and assessing strategic risk exposure, including a determination of the nature and level of risk appropriate for our company.

Our Audit Committee has the responsibility to consider and discuss with management and the auditors, as appropriate, our guidelines and policies with respect to financial risk management and financial risk assessment, including our major financial risk exposures and the steps taken by management to monitor and control these exposures. In addition, the Audit Committee considers management risks relating to data privacy, technology and information security, including cyber security, and back-up of information systems and the steps we have taken to monitor and control such exposures as well as overseeing the performance of our internal audit function, as applicable. Our Compensation Committee assesses and monitors whether any of our compensation policies and programs has the potential to encourage excessive risk-taking, including risks related to executive compensation and overall compensation and benefit strategies, plans, arrangements, practices and policies. Our Nominating and Corporate Governance Committee monitors the effectiveness of our corporate governance guidelines, including whether they are successful in preventing illegal or improper liability-creating conduct. The Nominating and Corporate Governance Committee also oversees and reviews with management our major legal compliance risk exposures and the steps management has taken to monitor or mitigate such exposures, including our procedures and any related policies with respect to risk assessment and risk management.

It is the responsibility of the committee chairs to report findings regarding material risk exposures to the Board as quickly as possible. In connection with its reviews of our operations and corporate functions, our Board addresses the primary risks associated with those operations and corporate functions. In addition, our Board reviews the risks associated with our business strategies periodically throughout the year as part of its consideration of undertaking any such business strategies. While the Board and its committees oversee risk management strategy, management is responsible for implementing and supervising day-to-day risk management processes and reporting to the Board and its committees on such matters.

The Board oversees our business and monitors the performance of our management. Our executive officers and management oversee our day-to-day operations. Our Board held nine meetings during 2025. Our Audit Committee met nine times in 2025, our Compensation Committee met five times and our Nominating and Corporate Governance Committee met four times. Each director attended at least 75% of the total of the meetings of the Board and committees of the Board on which such director served during 2025 (in each case, which were held during the period for which he or she was a director and/or a member of the applicable committee). It is our policy to encourage our directors to attend the Annual Meeting. All members of the Board attended the 2025 Annual Meeting of Stockholders, and we anticipate that all members of the Board will attend the upcoming Annual Meeting.

The independent directors of the Board meet routinely in executive sessions without management or any non-independent directors. The purpose of these executive sessions is to promote open and candid discussion among the non-employee directors. In 2025, our independent directors met three times in executive sessions at which only independent directors were present.

Our Board has established an Audit Committee, a Compensation Committee, and a Nominating and Corporate Governance Committee. The following table provides committee membership as of the date of this proxy statement for each of the standing committees of the Board

The Board has determined that Ms. Rollins is an "audit committee financial expert" within the meaning of the SEC regulations and applicable listing standards of Nasdaq. Each member of our Audit Committee can read and understand fundamental financial statements in accordance with applicable requirements. In arriving at these determinations, our Board has examined each Audit Committee member's scope of experience and the nature of their employment in the corporate finance sector.

The primary purpose of the Audit Committee is to discharge the responsibilities of our Board with respect to our corporate accounting and financial reporting processes, systems of internal control and financial statement audits, and to oversee our independent registered public accounting firm.

The Audit Committee's functions are more fully described in its charter, which is available in the Corporate Governance section of Xometry's website. Management has the primary responsibility for Xometry's financial statements and reporting processes, including Xometry's systems of internal controls.

The Audit Committee has reviewed and discussed the audited financial statements as of and for the fiscal year ended December 31, 2025 with management of Xometry.

Compensation Committee

Our Compensation Committee consists of Roy Azevedo, Ranjana Clark and Fabio Rosati, with Ms. Clark serving as Chair of the committee. Deborah Bial served on the committee until her departure from the Board in June 2025, at which time Mr. Azevedo joined the committee. Our Board has determined that each member of the Compensation Committee is independent under the Nasdaq listing standards and a "non-employee director" as defined in Rule 16b-3 promulgated under the Exchange Act.

The primary purpose of our Compensation Committee is to discharge the responsibilities of our Board in overseeing our compensation policies, plans and programs and to review and determine the compensation to be paid to our executive officers, directors and other senior management, as appropriate. Specific responsibilities of our Compensation Committee include:

helping the Board oversee our compensation policies, plans and programs with a goal to attract, incentivize, retain and reward top quality executive management and employees;

Compensation Committee Processes and Procedures

Typically, the Compensation Committee meets quarterly and with greater frequency if necessary. The agenda for each meeting is usually developed by the Chair of the Compensation Committee, in consultation with our Chief Executive Officer and our Chief Human Resources Officer. The Compensation Committee meets regularly in executive session. However, from time to time, various members of management and other employees as well as outside advisers or consultants may be invited by the Compensation Committee to make presentations, to provide financial or other background information or advice or to otherwise participate in Compensation Committee meetings. The Chief Executive Officer may not participate in, or be present during, any deliberations or determinations of the Compensation Committee regarding his compensation or individual performance objectives. The charter of the Compensation Committee grants the Compensation Committee full access to all books, records, facilities and personnel of Xometry. In addition, under the charter, the Compensation Committee has the authority to obtain, at our expense, advice and assistance from compensation consultants and internal and external legal, accounting or other advisers and other external resources that the Compensation Committee considers necessary or appropriate in the performance of its duties. The Compensation Committee has direct responsibility for the oversight of the work of any consultants or advisers engaged for the purpose of advising the Compensation Committee. In particular, the Compensation Committee has the authority to retain compensation consultants to assist in its evaluation of executive and director compensation, including authority to approve the consultant's reasonable fees and other retention terms. Under the charter, the Compensation Committee may select, or receive advice from, a compensation consultant, legal counsel or other adviser to the Compensation Committee, other than in-house legal counsel and certain other types of advisers, only after assessing the independence of such person in accordance with SEC and Nasdaq requirements that bear upon the adviser's independence; however, there is no requirement that any adviser be independent.

Compensation Committee Interlocks and Insider Participation

No member of our Compensation Committee is currently one of our officers or employees. None of our executive officers currently serves, or has served during the last year, as a member of the board of directors or compensation committee of any entity that has one or more executive officers serving as a member of our Board or Compensation Committee.

Nominating and Corporate Governance Committee

Our Nominating and Corporate Governance Committee consists of Ranjana Clark, Fabio Rosati and Katharine Weymouth, with Ms. Weymouth serving as Chair of the committee. Deborah Bial served on the committee until her departure from the Board in June 2025

The primary purpose of the Nominating and Corporate Governance Committee is to discharge the responsibilities of our board of directors with respect to our corporate governance functions and to identify, communicate with, evaluate and recommend candidates for our Board. Specific responsibilities of our Nominating and Corporate Governance Committee include:

helping the Board oversee our corporate governance functions and develop, update as necessary and recommend to the Board the governance principles applicable to Xometry;

identifying, evaluating and recommending and communicating with candidates qualified to become Board members or nominees for directors of the Board consistent with criteria approved by the Board;

making other recommendations to the Board relating to the directors;

reviewing any stockholder proposals submitted for inclusion in the Company's proxy statement and recommending to the Board any statements by the Company in response; and

reviewing and evaluating with the Board and the Chief Executive Officer the succession plans for the Company's executive officers and making recommendations to the Board with respect to the selection of appropriate individuals to succeed these positions.

Director Nomination Process

Our Board determines the appropriate characteristics, skills and experience for the Board as a whole and for its individual members. The Board considers recommendations for nominees from the Nominating and Corporate Governance Committee. The Board, and in turn the Nominating and Corporate Governance Committee, consider the minimum general criteria below, and may add any specific additional criteria with respect to specific searches, in selecting candidates and existing directors for serving on the Board. An acceptable candidate may not fully satisfy all of the criteria but is expected to satisfy nearly all of them. The Board believes that candidates for director should have certain minimum qualifications, including the highest personal integrity and ethics, the ability to read and understand basic financial statements, an understanding of our industry and being older than 21.

In considering candidates recommended by the Nominating and Corporate Governance Committee, the Board intends to consider other factors, such as: (i) possessing relevant expertise upon which to be able to offer advice and guidance to management;

(ii) having sufficient time to devote to our affairs; (iii) demonstrating excellence in the candidate's field; (iv) having the ability to exercise sound business judgment; (v) experience as a board member or executive officer of another publicly held company; and

(vi) having the commitment to rigorously represent the long-term interests of our stockholders.

The Board and the Nominating and Corporate Governance Committee review candidates for director nomination in the context of the current composition of the Board, our operating requirements and the long-term interests of Xometry's stakeholders. In conducting this assessment, the Board and the Nominating and Corporate Governance Committee consider diversity of experience, background, age, skills and other factors that it deems appropriate to maintain a balance of knowledge, experience and capability on the Board. Three of our six directors are women and two of our six directors identify as being racially or ethnically diverse. For incumbent directors, the Board reviews those directors' overall service to Xometry during their respective terms, including the number of meetings attended, level of participation, quality of performance and any other relationships and transactions that might impair the directors' independence. In the case of new director candidates, the Board also determines whether the nominee is independent for Nasdaq purposes.

Generally, our Nominating and Corporate Governance Committee identifies candidates for director nominees in consultation with management, using 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. The Nominating and Corporate Governance Committee conducts any appropriate and necessary inquiries into the backgrounds and qualifications of possible candidates after considering the function and needs of the Board. The Nominating and Corporate Governance Committee meets to discuss and consider the candidates' qualifications and then selects a nominee for recommendation to the Board by majority vote. The Nominating and Corporate Governance Committee may gather information about the candidates through interviews, questionnaires, background checks or any other means that the Nominating and Corporate Governance Committee deems to be appropriate in the evaluation process. We have no formal policy regarding board diversity. Our Nominating and Corporate Governance Committee's priority in selecting board members is identification of persons who will further the interests of Xometry through his or her established record of professional accomplishment, the ability to contribute positively to the collaborative culture among board members, professional and personal experiences and expertise relevant to our growth strategy.

The Nominating and Corporate Governance Committee will consider director candidates recommended by stockholders. The Nominating and Corporate Governance Committee does not intend to alter the manner in which it evaluates candidates, including the minimum criteria set forth above, based on whether or not the candidate was recommended by a stockholder. Stockholders who wish to recommend individuals for consideration by the Nominating and Corporate Governance Committee to become nominees for election to the Board may do so by providing notice in writing to our Secretary at Xometry, Inc., 6116 Executive Boulevard, Suite 800, North Bethesda, Maryland 20852, Attention: Secretary, subject to the notice requirements set forth below under "Other Information for Stockholders-Stockholder Proposals for the 2027 Annual Meeting of Stockholders."

We have adopted a Code of Business Conduct and Ethics that applies to all our employees, officers and directors. This includes our principal executive officer, principal financial officer and principal accounting officer or controller, or persons performing similar functions. The full text of our Code of Business Conduct and Ethics is posted on the "Investors-Corporate Governance" section of our website at https://www.xometry.com.

The Board has adopted Corporate Governance Guidelines to assure that the Board will have the necessary authority and practices in place to review and evaluate our business operations as needed and to make decisions that are independent of our management. The guidelines are also intended to align the interests of directors and management with those of our stockholders. The Corporate Governance Guidelines set forth the practices the Board intends to follow with respect to, among other things, board composition and selection, board meetings and involvement of senior management, Chief Executive Officer performance evaluation and succession planning, and board committees and compensation. The Corporate Governance Guidelines are available in the "Investors-Corporate Governance" section of our website at https://www.xometry.com

Stockholders wishing to communicate with the Board or an individual director may send a written communication to the Board or such director c/o Xometry, Inc., 6116 Executive Boulevard, Suite 800, North Bethesda, Maryland 20852, Attn: Secretary. The Secretary will review each communication and will forward such communication to the Board or to any individual director to whom the communication is addressed unless the communication contains advertisements or solicitations or is unduly hostile, threatening or similarly inappropriate, in which case the Secretary shall discard the communication or inform the proper authorities, as may be appropriate.

Our Board has adopted an Insider Trading Policy (the "Insider Trading Policy") governing the purchase, sale, and/or other dispositions of our securities by directors, officers and employees that we believe is reasonably designed to promote compliance with insider trading laws, rules and regulations and the Nasdaq listing standards. In addition, it is our company's intent to comply with applicable laws and regulations relating to insider trading. A copy of the Insider Trading Policy is filed as an exhibit to our Annual Report on Form 10-K for the fiscal year ended December 31, 2025.

The Insider Trading Policy prohibits our employees, directors, other applicable members of management and designated consultants from engaging in "hedging" or other monetization transactions with respect to our common stock, including through the use of financial instruments such as prepaid variable forwards, equity swaps, collars and exchange funds. In addition, the Insider Trading Policy prohibits trading in derivative securities related to our common stock, which include publicly traded call and put options, engaging in short selling of our common stock, and purchasing our common stock on margin or holding it in a margin account

The Insider Trading Policy prohibits our employees, directors, other applicable members of management and designated consultants from pledging our common stock as collateral for a loan.

Under the Dodd-Frank Wall Street Reform and Consumer Protection Act (the "Dodd-Frank Act") and Section 14A of the Exchange Act, our stockholders are entitled to vote to approve, on an advisory basis, the compensation of our named executive officers as disclosed in this proxy statement under "Executive Compensation-Compensation Discussion and Analysis," the tables included under the heading "Executive Compensation" and the accompanying narrative discussion.

This vote is not intended to address any specific item of compensation, but rather the overall compensation of our named executive officers and the philosophy, policies and practices described in this proxy statement. The compensation of our named executive officers subject to the vote is disclosed in the compensation tables and the related narrative disclosures that accompany the compensation tables contained in the "Executive Compensation" section in this proxy statement. As discussed in those disclosures, we believe that our compensation policies and decisions are strongly aligned with our stockholders' interests and consistent with current market practices. Compensation of our named executive officers is designed to enable us to attract and retain talented and experienced executives to lead us successfully in a competitive environment.

Accordingly, the Board is asking the stockholders to indicate their support for the compensation of our named executive officers as described in this proxy statement by casting a non-binding advisory vote "FOR" the following resolution:

"RESOLVED, that the compensation paid to the named executive officers of Xometry, Inc., as disclosed pursuant to Item 402 of Regulation S-K, including the Compensation Discussion and Analysis, compensation tables and narrative discussion, is hereby APPROVED."

Because the vote is advisory, it is not binding on the Board or the Compensation Committee. Nevertheless, the views expressed by the stockholders, whether through this vote or otherwise, are important to management and the Board and, accordingly, the Board and the Compensation Committee intend to consider the results of this vote in making determinations in the future regarding executive compensation arrangements.

The following table sets forth, for our executive officers, their ages and positions held with us as of the date of this proxy tatement

Compensation Program Objectives, Philosophy and Elements of Compensation

The main objectives of our executive compensation program are to:

motivate, attract and retain highly qualified executives who are committed to our mission, performance and culture by paying them competitively;

create a fair, reasonable and balanced compensation program that rewards executives' performance and contributions to our short- and long-term business results, while closely aligning the interests of the executives with those of our stockholders; and

emphasize pay for performance, with a program that aligns compensation with financial and operational achievements.

We believe that our executive compensation program accomplishes the following:

ensures executives are not motivated to take excessive risks to achieve a reasonable level of financial security by providing base salaries consistent with each executive's responsbilities;

aligns executive interests with those of our stockholders by tying a significant portion of their compensation to our future share performance;

encourages executives to remain employed and focused on sustained share price appreciation via equity compensation with multi-year vesting periods; and

encourages strategies and actions that are in the long-term best interests of Xometry and our stockholders via a mix between cash and equity compensation.

To achieve our compensation objectives, we have historically provided our executive officers, including our named executive officers, with a compensation package consisting of the following elements:

Base Salary

(fixed compensation)

(variable, at-risk compensation)

Provides financial stability and security through a fixed salary for performing job responsibilities.

Motivates and rewards employees for achieving rigorous annual corporate and individual performance goals that relate to our key business objectives.

The base salary of each executive, including each named executive officer, generally is determined and recommended for approval by the Board by our Compensation Committee in connection with the commencement of such person's employment and may be adjusted from time to time thereafter as the Board determines appropriate.

Base salaries generally are reviewed annually at the beginning of the fiscal year, and any increases are based on a number of factors (including the value of current equity awards; scope and complexity of role; and experience, qualifications and skills) and by reference to market data provided by Meridian Compensation Partners, LLC ("Meridian"), the Compensation Committee's independent compensation consultant.

The Compensation Committee generally provides our eligible executives, including our named executive officers, an opportunity to earn annual cash bonus awards contingent upon the attainment of certain individual and company performance targets as established by the Compensation Committee or the Board. Each executive's bonus award payout is determined by multiplying the executive's target bonus opportunity (expressed as a percentage of the executive's annual base salary) by the percentage of achievement as determined by the Compensation Committee.

Target bonus opportunities are generally reviewed annually at the beginning of the fiscal year and determined based upon a review of competitive market data drawn from the peer group and broad compensation surveys.

In evaluating our executive compensation policies and programs, as well as the targeted short- and long-term value of our executive compensation plans, the Compensation Committee considers both the performance and skills of each of our executives, as well as the compensation paid to executives in similar companies with similar responsibilities. We focus on providing a competitive compensation package which provides significant short- and long-term incentives for the achievement of measurable corporate objectives. We believe that this approach provides an appropriate blend of short- and long-term incentives to maximize stockholder value

We do not have any formal policies for allocating compensation among salary, annual performance-based cash bonus awards and equity grants, short- and long-term compensation, or among cash and non-cash compensation. Instead, the Compensation Committee uses market benchmarks as a starting point to establish a total compensation program for each executive that consists of a mix of short-term incentive and long-term incentive compensation and cash and non-cash compensation that it believes appropriate to achieve the objectives of our executive compensation program. Further, a significant portion of each executive's total target compensation consists of performance-based bonus opportunities and long-term equity awards in order to align our executive officers' incentives with the interests of our stockholders and the achievement of our corporate goals.

In making executive compensation decisions, the Compensation Committee generally considers each executive officer's total target direct compensation, which consists of base salary, target bonus opportunity (which, together with base salary, we refer to as target cash compensation) and long-term equity awards (valued based on an approximation of grant date fair value).

How We Determine Executive Compensation

Role of Our Compensation Committee, Management and the Board

Our Compensation Committee is appointed by the Board to assist with the Board's oversight responsibilities with respect to our compensation and benefit plans, policies and programs, administration of our equity plans and the Board's responsibilities related to the compensation of our executive officers, directors and senior management, as appropriate.

The Compensation Committee is primarily responsible for establishing and reviewing our general compensation strategy. The Compensation Committee generally meets quarterly, and with greater frequency if necessary, to, among other responsibilities, manage and evaluate our executive compensation program, and generally determines, subject to final Board approval, the principal components of compensation (base salary, annual performance-based cash bonus awards and equity awards) for our executive officers on an annual basis. However, decisions may occur at other times for new hires, promotions or other special circumstances as the Compensation Committee determines appropriate. The Compensation Committee does not delegate authority to approve executive officer compensation. The Compensation Committee generally reviews and determines equity-based incentive awards annually at the beginning of the fiscal year or as appropriate during the year for new hires, promotions, or other special circumstances, such as retention. The Compensation Committee will continue to evaluate its equity grant policies as we continue to evolve and grow as a public company.

The Compensation Committee works with and receives information and analyses from our Chief Executive Officer and our human resources department, and considers such information and analyses in determining the structure and amount of compensation to be paid to our executive officers, including our named executive officers. Our Chief Executive Officer evaluates and discusses with the Compensation Committee executive officer performance assessments and management's recommendations and proposals regarding executive officer compensation programs and decisions affecting base salaries, equity compensation and other compensation-related matters outside of the presence of any other named executive officer. Our Chief People Officer discusses with the Compensation Committee role levels and compensation benchmarking. However, the Board retains the final authority to make all compensation decisions. While our Chief Executive Officer discusses his recommendations with the Compensation Committee for executive officers other than himself, he does not participate in the deliberations concerning, or the determination of, his own compensation.

Role of Compensation Consultant

The Compensation Committee has retained Meridian as its independent compensation consultant since 2021 due to its extensive analytical and compensation expertise relating to technology companies. Meridian reports directly to the Compensation Committee and does not provide any services to our company other than data and advice related to executive and director compensation matters. The Compensation Committee has analyzed whether the work of Meridian as the compensation consultant raised any conflict of interest, after taking into consideration the six factors prescribed by the SEC and Nasdaq. Based on its analysis, the Compensation Committee determined that the work of Meridian and the individual compensation advisors have conformed to the independence factors and guidance provided by the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, the SEC and the Nasdaq listing standards.
