#### Letter to Shareholders

#### April 17, 2026
To Our Shareholders:

You are cordially invited to attend the 2026 annual meeting of shareholders of TMC the metals company Inc. (the "Company") to be held in a virtual format on Thursday, May 28, 2026 at 10:00 a.m. EDT.

This year's annual meeting will be held virtually via live audio webcast on the internet. We believe hosting a virtual annual meeting enables greater shareholder attendance and participation from any location around the world, improves meeting efficiency and our ability to communicate effectively with our shareholders, and reduces the cost and environmental impact of our annual meeting. You will be able to attend the annual meeting, vote and submit your questions during the annual meeting by visiting *https://www.cstproxy.com/metals/2026*. You will not be able to attend the annual meeting in person.

Details regarding the meeting, the business to be conducted at the meeting, and information about the Company that you should consider when you vote your shares are described in the accompanying proxy statement.

At the annual meeting, we will present the audited consolidated financial statements for the fiscal year ended December 31, 2025 and the auditors' report thereon. We will ask shareholders to set the number of directors at ten and to elect ten persons to our board of directors. In addition, we will ask shareholders to appoint Ernst & Young LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2026. We will also ask shareholders to approve on an advisory basis the compensation of our named executive officers, as disclosed in the accompanying proxy statement, and to approve on an advisory basis the frequency for holding an advisory vote on such compensation. Our board of directors recommends approval of the proposals to set the number of directors at ten, elect the director nominees, ratify the appointment of the independent auditor, and approve the Company's executive compensation, and a frequency of every two years for advisory votes on executive compensation.

Under the Securities and Exchange Commission rules that allow companies to furnish proxy materials to shareholders over the Internet, we have elected to deliver our proxy materials to the majority of our shareholders over the Internet. This delivery process allows us to provide shareholders with the information they need, while at the same time conserving natural resources and lowering the cost of delivery. On or about April 17, 2026, we intend to begin sending to our shareholders a Notice of Internet Availability of Proxy Materials (the "Notice") containing instructions on how to access our proxy statement for the annual meeting and our annual report to shareholders. The Notice also provides instructions on how to vote by proxy, online or at the meeting, how to access the virtual annual meeting and how to receive a paper copy of the proxy materials by mail.

We hope you will be able to attend the annual meeting. Whether or not you plan to attend the annual meeting, we hope you will vote promptly. Information about voting methods is set forth in the accompanying proxy statement.

Thank you for your continued support of the Company. We look forward to seeing you at the annual meeting.

Sincerely,

This proxy statement relates to the solicitation of proxies by our board of directors for use at the Annual Meeting.

On or about April 17, 2026, we intend to begin sending to our shareholders the Important Notice Regarding the Availability of Proxy Materials containing instructions on how to access our proxy statement for the Annual Meeting and our annual report to shareholders.

#### IMPORTANT INFORMATION ABOUT THE ANNUAL MEETING AND VOTING

#### Why is the Company soliciting my proxy?
Our board of directors is soliciting your proxy to vote at the 2026 annual meeting of shareholders of TMC the metals company Inc. (the "Annual Meeting") to be held virtually on Thursday, May 28, 2026, at 10:00 a.m. EDT and any adjournments or postponements of the meeting. This proxy statement, along with the accompanying Notice of Annual Meeting of Shareholders, summarizes the purposes of the meeting and the information you need to know to vote at the Annual Meeting.

We have made available to you on the Internet or have sent you this proxy statement, the Notice of Annual Meeting of Shareholders, the proxy card and a copy of our 2026 annual report to shareholders because you owned our common shares on the record date. We intend to commence distribution of the Important Notice Regarding the Availability of Proxy Materials, which we refer to throughout this proxy statement as the "Notice of Internet Availability" or the "Notice", and, if applicable, proxy materials to shareholders on or about April 17, 2026.

#### Why did I receive a Notice in the mail regarding the Internet availability of proxy materials instead of a full set of proxy materials?
As permitted by the rules of the Securities and Exchange Commission (the "SEC"), we may furnish our proxy materials to our shareholders by providing access to such documents on the Internet, rather than mailing printed copies of these materials to each shareholder. Most shareholders will not receive printed copies of the proxy materials unless they request them. We believe that this process should expedite shareholders' receipt of proxy materials, lower the costs of the Annual Meeting and help to conserve natural resources. If you received the Notice by mail or electronically, you will not receive a printed or email copy of the proxy materials, unless you request one by following the instructions included in the Notice. Instead, the Notice instructs you as to how you may access and review all of the proxy materials and submit your proxy on the Internet. If you requested a paper copy of the proxy materials, you may authorize the voting of your shares by following the instructions on the proxy card, in addition to the other methods of voting described in this proxy statement.

#### Why are you holding a virtual Annual Meeting?
This year's Annual Meeting will be held in a virtual meeting format only. We have designed our virtual format to enhance, rather than constrain, shareholder access, participation and communication. For example, the virtual format allows shareholders to communicate with us in advance of, and during, the Annual Meeting so they can ask questions of our board of directors or management, as time permits.

#### How do I access the virtual Annual Meeting?
The live audio webcast of the Annual Meeting will begin promptly at 10:00 a.m. EDT. Online access to the audio webcast will open 15 minutes prior to the start of the Annual Meeting to allow time for you to log-in and test your device's audio system. The virtual Annual Meeting is running the most updated version of the applicable software and plugins. You should ensure you have a strong Internet connection wherever you intend to participate in the Annual Meeting. You should also allow plenty of time to log in and ensure that you can hear streaming audio prior to the start of the Annual Meeting.

To be admitted to the virtual Annual Meeting, you will need to log-in at *https://www.cstproxy.com/metals/2026* using the 12-digit control number found on the proxy card or voting instruction card previously mailed or made available to shareholders entitled to vote at the Annual Meeting.

#### Will I be able to ask questions and have these questions answered during the virtual Annual Meeting?
Shareholders may submit questions for the Annual Meeting after logging in. If you wish to submit a question, you may do so by logging into the virtual meeting platform at *https://www.cstproxy.com/metals/2026*, typing your question into the "Ask a Question" field, and clicking "Submit." Please submit any questions before the start time of the meeting.

------

[**TABLE OF CONTENTS**](#TOC)

Appropriate questions related to the business of the Annual Meeting (the proposals being voted on) will be answered during the Annual Meeting, subject to time constraints. Any such questions that cannot be answered during the Annual Meeting due to time constraints will be answered directly with the shareholder as soon as practical after the Annual Meeting. Additional information regarding the ability of shareholders to ask questions during the Annual Meeting, related to rules of conduct and other materials for the Annual Meeting will be available on the virtual meeting platform available at the web address above.

In addition, we have made available a separate conference line to allow attendees to communicate with each other during the Annual Meeting. Attendees who wish to utilize this facility may do so by dialing the attendee conference line number shown on the right-hand side of the meeting webpage under the heading "Attendee conference line". Please note, however, that the attendee conference line is to allow attendees to communicate with each other during the meeting only and cannot be used to listen to the meeting or for asking questions to the Company.

#### What happens if there are technical difficulties during the Annual Meeting?
Beginning 15 minutes prior to, and during, the Annual Meeting, we will have technicians ready to assist you with any technical difficulties you may have accessing the virtual Annual Meeting, voting at the Annual Meeting or submitting questions at the Annual Meeting. If you encounter any difficulties accessing the virtual Annual Meeting during the check-in or meeting time, please call (917) 262-2373.

#### Who may vote?
Only shareholders of record at the close of business on April 2, 2026 (the "Record Date") will be entitled to vote at the Annual Meeting. On this Record Date, there were 433,188,187 common shares outstanding and entitled to vote. Our common shares are our only class of voting stock.

If on the Record Date your common shares were registered directly in your name with our transfer agent, Continental Stock Transfer and Trust Company, then you are a shareholder of record.

If on the Record Date you did not hold your shares 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 is being forwarded to you by that organization. The organization holding your account is considered to be the shareholder of record for purposes of voting at the Annual Meeting. As a beneficial owner, you have the right to direct your broker 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 shareholder of record, you may not vote your shares at the Annual Meeting unless you request and obtain a valid proxy from your broker or other agent.

You do not need to attend the Annual Meeting to vote your shares. Shares represented by valid proxies, received in time for the Annual Meeting and not revoked prior to the Annual Meeting, will be voted at the Annual Meeting. For instructions on how to change or revoke your proxy, see "*May I change or revoke my proxy?*" below.

#### How many votes do I have?
Holders of common shares are entitled to one vote per share.

#### How do I vote?
Whether you plan to attend the Annual Meeting or not, we urge you to vote by proxy. All shares represented by valid proxies that we receive through this solicitation, and that are not revoked, will be voted in accordance with your instructions on the proxy card or as instructed via the Internet. You may specify whether your shares should be voted FOR or WITHHELD for each nominee for director, as well as for Proposal No. 3, and whether your shares should be voted FOR, AGAINST or ABSTAIN with respect to Proposal No. 1 and Proposal No. 4 and whether your shares should be voted for 1 YEAR, 2 YEARS, 3 YEARS or ABSTAIN on Proposal No. 5. If you properly submit a proxy without giving specific voting

[**TABLE OF CONTENTS**](#TOC)

instructions, your shares will be voted in accordance with our board of directors' recommendations as noted below. Voting by proxy will not affect your right to attend the Annual Meeting.

If your shares are registered directly in your name through our stock transfer agent, Continental Stock Transfer and Trust Company, or you have stock certificates registered in your name, you may vote:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • **By Internet.** Follow the instructions included in the Notice or, if you received printed materials, in the proxy card to vote over the Internet.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • **By mail.** If you received a proxy card by mail, you can vote by mail by completing, signing, dating and returning the proxy card as instructed on the card. If you sign the proxy card but do not specify how you want your shares voted, they will be voted in accordance with our board of directors' recommendations as noted below.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • **At the meeting.** If you attend the virtual Annual Meeting, you may vote by completing a ballot, which will be available at the meeting.

 **Internet voting facilities for shareholders of record will be available 24 hours a day and will close at 11:59 p.m. Eastern Daylight Time on May 27, 2026.** 

If your shares are held in "street name" (held in the name of a bank, broker or other holder of record), you will receive instructions from the holder of record. You must follow the instructions of the holder of record in order for your shares to be voted. Internet voting also will be offered to shareholders owning shares through certain banks and brokers. If your shares are not registered in your own name and you plan to vote your shares virtually at the Annual Meeting, you should contact your broker or agent to obtain a legal proxy or broker's proxy card for use at the Annual Meeting in order to vote.

#### How does our board of directors recommend that I vote on the proposals?
Our board of directors recommends that you vote as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • "**FOR**" the approval of setting the number of directors at ten (10)**;** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • "**FOR**" the election of the nominees for director;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • "**FOR**" the appointment of Ernst & Young LLP as our independent registered public accounting firm for our fiscal year ending December 31, 2026;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • "**FOR**" the compensation of our named executive officers, as disclosed in this proxy statement; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • In favor of "**2 YEARS**" as the frequency of holding an advisory vote on the compensation of our named executive officers.

If any other matter is presented at the Annual Meeting, your proxy provides that your shares will be voted by the proxy holder listed in the proxy in accordance with the proxy holder's judgment. At the time this proxy statement was first made available, we knew of no matters that needed to be acted on at the Annual Meeting, other than those discussed in this proxy statement.

#### May I change or revoke my proxy?
If you give us your proxy, you may change or revoke it at any time before the Annual Meeting. In addition to any method permitted under applicable law, you may change or revoke your proxy in any one of the following ways:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • if you received a proxy card, by signing a new proxy card with a date later than your previously delivered proxy and submitting it as instructed above;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • by re-voting by Internet as instructed above;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • by notifying the Company's Secretary in writing before the Annual Meeting that you have revoked your proxy; or

------

[**TABLE OF CONTENTS**](#TOC)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • by attending the Annual Meeting virtually and voting at the meeting. Attending the Annual Meeting will not in and of itself revoke a previously submitted proxy. You must specifically request at the Annual Meeting that it be revoked.

Your most current vote, whether by Internet or proxy card is the one that will be counted.

#### Can I appoint some other person to be my proxyholder?
Every holder of common shares has the right to appoint some other person or company of their choice, who need not be a security holder, to attend and act on their behalf at the Annual Meeting or any adjournment or postponement thereof. If you wish to appoint a person or company other than Gerard Barron and Craig Shesky or their substitute, please deliver a proxy in the form contemplated in our Articles (the "Articles"), a copy of which is available at 1111 West Hastings Street, 15<sup>th</sup> Floor, Vancouver, British Columbia V6E 2J3 or on the website of the SEC — *www.sec.gov*, naming your chosen proxyholder and deposit such proxy at the registered and records office of the Company at 1111 West Hastings Street, 15<sup>th</sup> Floor, Vancouver, British Columbia V6E 2J3.

#### What if I receive more than one Notice or proxy card?
You may receive more than one Notice or proxy card if you hold our common shares in more than one account, which may be in registered form or held in street name. Please vote in the manner described above under "*How do I vote?*" for each account to ensure that all of your shares are voted.

#### Will my shares be voted if I do not vote?
If your shares are registered in your name or if you have stock certificates, they will not be counted if you do not vote as described above under "*How do I vote?*" If your shares are held in street name and you do not provide voting instructions to the bank, broker or other nominee that holds your shares as described above, the bank, broker or other nominee that holds your shares has the authority to vote your unvoted shares to set the number of directors at ten (10): (Proposal No. 1 of this proxy statement) and on the appointment of our independent registered public accounting firm (Proposal No. 3 of this proxy statement) without receiving instructions from you. Although brokers are granted the discretion to vote your shares absent your instruction on these proposals, some brokers may elect not to vote your shares without an instruction from you. Additionally, a "broker non-vote" will occur if your broker cannot vote your shares on a particular matter because it has not received instructions from you and does not have discretionary voting authority on that matter. Therefore, we encourage you to provide voting instructions to your bank, broker or other nominee. This ensures your shares will be voted at the Annual Meeting and in the manner you desire.

#### What vote is required to approve each proposal and how are votes counted?

---

| | |
|:---|:---|
| **Proposal No. 1: Set Number of Directors at Ten**  | The affirmative vote of a majority of the shares cast for this proposal is required to set the number of directors at ten**.** You may either vote FOR, AGAINST or ABSTAIN on this proposal. Abstentions, if any, and broker non-votes will have no effect on the results of this vote. Brokerage firms have authority to vote customers' unvoted shares held by the firms in street name on this proposal. Accordingly, we do not expect broker non-votes on this proposal.  |
| **Proposal No. 2: Elect Directors**  | The nominees for director who receive the most votes (also known as a "plurality" of the votes cast) will be elected. You may vote either FOR all of the nominees, WITHHOLD your vote from all of the nominees or WITHHOLD your vote from any one or more of the nominees. Votes that are withheld will not be included in the vote tally for the election of the directors. Brokerage firms do not have authority to vote customers' unvoted shares held by the firms  |

|  | in street name for the election of the directors. As a result, any shares not voted by a customer will be treated as a broker non-vote. Such broker non-votes will have no effect on the results of this vote.  |
| **Proposal No. 3: Appoint the Independent Registered Public Accounting Firm**  | The "plurality" of the votes cast for this proposal is required to appoint our independent registered public accounting firm. You may vote FOR the appointment of Ernst & Young LLP or WITHHOLD your vote. Votes that are withheld will not be included in the vote tally for this proposal. Broker non-votes will have no effect on the results of this vote. Brokerage firms have authority to vote customers' unvoted shares held by the firms in street name on this proposal. Accordingly, we do not expect broker non-votes on this proposal.  |
| **Proposal No. 4: Approve a Non-Binding Advisory Vote on the Compensation of our Named Executive Officers**  | The affirmative vote of a majority of the shares cast for this proposal is required to approve, on an advisory basis, the compensation of our named executive officers, as described in this proxy statement. You may either vote FOR, AGAINST or ABSTAIN on this proposal. Abstentions, if any, will have no effect on the results of this vote. Brokerage firms do not have authority to vote customers' unvoted shares held by the firms in street name on this proposal. As a result, any shares not voted by a customer will be treated as a broker non-vote. Such broker non-votes will have no effect on the results of this vote. Although the advisory vote is non-binding, the compensation committee and our board of directors will review the voting results and take them into consideration when making future decisions regarding the compensation of our named executive officers.  |
| **Proposal No. 5: Approve a Non-Binding Advisory Vote on the Frequency of Holding an Advisory Vote on Compensation of our Named Executive Officers**  | The frequency of holding an advisory vote on the compensation of our named executive officers — one year, two years or three years — receiving the majority of votes cast will be the frequency approved by our shareholders. You may either vote 1 YEAR, 2 YEARS, 3 YEARS or ABSTAIN on this proposal. Brokerage firms do not have authority to vote customers' unvoted shares held by the firms in street name on this proposal. As a result, any shares not voted by a customer will be treated as a broker non-vote. Such broker non-votes, as well as abstentions, will have no effect on the results of this vote. Our board of directors recommends a vote of 2 YEARS on this proposal and although the advisory vote is non-binding, the compensation committee and our board of directors will review the voting results (including reviewing the frequency that receives the highest number of votes if no choice receives a majority of the votes cast) and take them into consideration when determining the frequency of holding an advisory vote on the compensation of our named executive officers for the next six years.  |

#### What are the costs of soliciting these proxies?
We will pay all of the costs of soliciting these proxies. Our directors and employees may solicit proxies in person or by telephone, fax or email. We will pay these employees and directors no additional compensation for these services. We will ask banks, brokers and other institutions, nominees and fiduciaries to forward these proxy materials to their principals and to obtain authority to execute proxies. We will then reimburse them for their expenses.

#### What constitutes a quorum for the Annual Meeting?
Our Articles require the presence, in person or by proxy, of two persons who are, or who represent by proxy, shareholders who, in the aggregate, hold at least 5% of the issued shares entitled to be voted at the Annual Meeting to constitute a quorum at the Annual Meeting. Additionally, the Nasdaq requires the presence, in person or by proxy, of the holders of at least 33<sup>1</sup>∕3% of the issued common shares entitled to vote at the Annual Meeting be so present. Votes of shareholders of record who are present at the Annual Meeting in person or by proxy, abstentions, and broker non-votes are counted for purposes of determining whether a quorum exists.

If a quorum is not present within one half hour from the time set for the holding of the Annual Meeting, the meeting stands adjourned to the same day in the next week at the same time and place or at such other date, time or location as the chair of the meeting specifies on the adjournment.

#### Attending the Annual Meeting
The Annual Meeting will be held in a virtual meeting format only. You can attend the Annual Meeting and view the live audio webcast by visiting *https://www.cstproxy.com/metals/2026*. The Annual Meeting will be held at 10:00 a.m. EDT on Thursday, May 28, 2026. To attend the virtual Annual Meeting, go to *https://www.cstproxy.com/metals/2026* shortly before the meeting time, enter your name, email address and control number to enter the meeting portal.

#### Householding of Annual Disclosure Documents
Some brokers or other nominee record holders may be sending you a single set of our proxy materials if multiple of the Company's shareholders live in your household. This practice, which has been approved by the SEC, is called "householding." Once you receive notice from your broker or other nominee record holder that it will be "householding" our proxy materials, the practice will continue until you are otherwise notified or until you notify them that you no longer want to participate in the practice. Shareholders who participate in householding will continue to have access to and utilize separate proxy voting instructions.

We will promptly deliver a separate copy of our Notice or if applicable, our proxy materials to you if you write to our corporate secretary at: 1111 West Hastings Street, 15<sup>th</sup> Floor, Vancouver, British Columbia V6E 2J3. If you want to receive your own set of our proxy materials in the future or, if you share an address with another shareholder and together both of you would like to receive only a single set of proxy materials, you should contact your broker or other nominee record holder directly or you may contact us at the above address and phone number.

#### Electronic Delivery of Company Shareholder Communications
Most shareholders can elect to view or receive copies of future proxy materials over the Internet instead of receiving paper copies in the mail.

You can choose this option and save us the cost of producing and mailing these documents by:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • following the instructions provided on your Notice or proxy card;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • following the instructions provided when you vote over the Internet; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • going to *https://www.cstproxy.com/metals/2026* and following the instructions provided.

#### Independence of the Board of Directors
Nasdaq rules generally require that independent directors must comprise a majority of a listed company's board of directors. Based upon information requested from and provided by each director concerning his or her background, employment and affiliations, including family relationships, the board of directors has determined that the following director nominees are "independent" as that term is defined under the applicable rules and regulations of the SEC and the listing requirements and rules of the Nasdaq: Andrew Greig (Lead Independent Director), Andrew Hall, Sheila Khama, Christian Madsbjerg, Andrei Karkar and Brendan May, representing six (6) of the Company's ten (10) directors.

#### Committees of our Board of Directors and Meetings

#### Meeting Attendance
During the year ended December 31, 2025, there were seven meetings of our board of directors, and the various committees of our board of directors met a total of 12 times. The board of directors and its committees also took action by unanimous written consent from time to time. No director attended fewer than 75% of the total number of meetings of our board of directors and of committees of our board of directors on which he or she served during fiscal 2025. Each member of our board of directors is strongly encouraged but is not required to attend each annual meeting of our shareholders. All directors attended our annual meeting of shareholders held in 2025.

#### Audit Committee
Our audit committee met six times during fiscal 2025 and acted by written consent outside of its meetings. Our audit committee currently consists of Andrew Hall, who serves as the chairperson, Christian Madsbjerg and Sheila Khama. Each member of the audit committee qualifies as an independent director under the Nasdaq Listing Rules and the independence requirements of Rule 10A-3 under the Securities Exchange Act of 1934, as amended.

The purpose of the audit committee is to prepare the audit committee report required by the SEC to be included in our proxy statement and to assist the board of directors in overseeing and monitoring (1) the quality and integrity of the financial statements, (2) compliance with legal and regulatory requirements, (3) our independent registered public accounting firm's qualifications and independence, (4) the performance of our internal audit function and (5) the performance of our independent registered public accounting firm.

The board of directors has adopted a written charter for the audit committee, which is available on the Company's website at *www.metals.co* under Investors — Governance — Corporate Governance Overview — Committee Charters.

#### Compensation Committee
Our compensation committee met one time during the year ended December 31, 2025 and acted by written consent outside of its meetings. Our compensation committee currently consists of Andrei Karkar, who serves as the chairperson, and Andrew Greig. All members of the compensation committee qualify as independent under the definition promulgated by Nasdaq.

The purpose of the compensation committee is to assist the board of directors in discharging its responsibilities relating to (1) setting our compensation program and compensation of its executive officers and directors, (2) monitoring our incentive and equity-based compensation plans and (3) preparing the compensation committee report, if any, required to be included in our proxy statement under the rules and regulations of the SEC.

The board of directors has adopted a written charter for the compensation committee, which is available on the Company's website at *www.metals.co* under Investors — Governance — Corporate Governance Overview — Committee Charters.

The compensation committee has adopted the following processes and procedures for the consideration and determination of executive and director compensation:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • The compensation committee's independent compensation consultant during the year ended December 31, 2025 was Frederic W. Cook & Co. ("FW Cook"). FW Cook is engaged by, and reports directly to, the compensation committee, which has the sole authority to hire or fire FW Cook and to approve fee arrangements for work performed. FW Cook assists the compensation committee in fulfilling its responsibilities under its charter, including advising on proposed compensation packages for executive officers, compensation program design and market practices generally. The compensation committee has authorized FW Cook to interact with management on behalf of the compensation committee, as needed in connection with advising the compensation committee, and FW Cook is included in discussions with management and, when applicable, the compensation committee's outside legal counsel on matters being brought to the compensation committee for consideration.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • It is the compensation committee's policy that the chair of the compensation committee or the full compensation committee pre-approve any additional services provided to management by our independent compensation consultant. In the year ended December 31, 2025, FW Cook only did work for the compensation committee. The compensation committee has assessed the independence of FW Cook pursuant to SEC rules and concluded that FW Cook's work for the compensation committee does not raise any conflict of interest.

The compensation committee also administers our clawback policy described below.

#### Nominating and Corporate Governance Committee
Our nominating and corporate governance committee met two times during the year ended December 31, 2025 and acted by written consent outside of its meetings. Our nominating and corporate governance committee currently consists of Christian Madsbjerg, who serves as the chairperson, Sheila Khama and Andrei Karkar. The purpose of the nominating and corporate governance committee is to assist the board of directors in discharging its responsibilities relating to (1) identifying individuals qualified to become new board of directors members, consistent with the criteria approved by the board of directors, (2) reviewing the qualifications of incumbent directors to determine whether to recommend them for re-election and selecting, or recommending that the board of directors select, the director nominees for the next annual meeting of shareholders, (3) identifying members of the board of directors qualified to fill vacancies on any committee of the board of directors and recommending that the board of directors appoint the identified member or members to the applicable committee, (4) reviewing and recommending to the board of directors corporate governance principles applicable to the Company,

(5) overseeing the evaluation of the board of directors and management and (6) handling such other matters that are specifically delegated to the committee by the board of directors from time to time.

The board of directors has adopted a written charter for the nominating and corporate governance committee, which is available on the Company's website at *www.metals.co* under Investors — Governance — Corporate Governance Overview — Committee Charters.

Generally, our nominating and corporate governance committee considers candidates recommended by shareholders as well as from other sources such as other directors or officers, third party search firms or other appropriate sources. Once identified, the nominating and corporate governance committee will evaluate a candidate's qualifications in accordance with our nominating and corporate governance committee's written charter. Threshold criteria include: personal integrity and sound judgment, business and professional skills and experience, independence, knowledge of our industry, possible conflicts of interest, diversity, the extent to which the candidate would fill a present need on our board of directors, and concern for the long-term interests of our shareholders. The nominating and corporate governance committee has not adopted a formal diversity policy in connection with the consideration of director nominations or the selection of nominees. However, the nominating and corporate governance committee will consider issues of diversity among its members in identifying and considering nominees for director and strive where appropriate to achieve a diverse balance of backgrounds, perspectives, experience, age, gender, ethnicity and country of citizenship on our board of directors and its committees.

In general, persons recommended by shareholders will be considered in accordance with our nominating and corporate governance committee's written charter. Any such recommendation should be made in writing to the nominating and corporate governance committee, care of our Corporate Secretary at our principal office and should be accompanied by the following information concerning each recommending shareholder and the beneficial owner**,** if any, on whose behalf the nomination is made:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • all information relating to such person that would be required to be disclosed in a proxy statement;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • certain biographical and share ownership information about the shareholder and any other proponent, including a description of any derivative transactions in the Company's securities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • a description of certain arrangements and understandings between the proposing shareholder and any beneficial owner and any other person in connection with such shareholder nomination; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • a statement whether or not either such shareholder or beneficial owner intends to deliver a proxy statement and form of proxy to holders of voting shares sufficient to carry the proposal.

The recommendation must also be accompanied by the following information concerning the proposed nominee:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • certain biographical information concerning the proposed nominee;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • all information concerning the proposed nominee required to be disclosed in solicitations of proxies for election of directors;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • certain information about any other security holder of the Company who supports the proposed nominee;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • a description of all relationships between the proposed nominee and the recommending shareholder or any beneficial owner, including any agreements or understandings regarding the nomination; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • additional disclosures relating to shareholder nominees for directors, including completed questionnaires and disclosures required by our Articles.

If a shareholder wishes to nominate a candidate for election to our board of directors at a future annual general meeting of our shareholders, it must follow the procedures described in the Articles and in "*Shareholder Proposals and Nominations for Director*" at the end of this proxy statement.

#### Sustainability and Innovation Committee
Our sustainability and innovation committee met three times during the year ended December 31, 2025. Our sustainability and innovation committee currently consists of Brendan May, who serves as the chairperson, Christian Madsbjerg and Sheila Khama.

The purpose of the sustainability and innovation committee is to assist the board of directors in discharging its responsibilities relating to oversight of our policies, programs, performance and related risks and opportunities that concern key sustainability and innovation matters, including issues of significance to us and our stakeholders that may affect its business, strategy, operations, performance, or reputation.

The board of directors has adopted a written charter for the sustainability and innovation committee, which is available on the Company's website at *www.metals.co* under Investors — Governance — Corporate Governance Overview — Committee Charters.

#### Board Leadership Structure
The positions of Chairman of the Board of Directors and Chief Executive Officer of the Company have historically been combined, and Gerard Barron currently holds both positions. We believe this board leadership structure is appropriate because of the efficiencies and institutional history with the positions held by Mr. Barron as the former chief executive officer and chairman of DeepGreen and of the subsequent combined entity following the closing of the Business Combination. Mr. Barron possesses the detailed knowledge of our day-to-day operations and this has both informed and supported the decision-making processes of the board of directors as a whole.

We believe we have a strong governance structure in place, including the appointment of a Lead Independent Director (currently Mr. Greig) and having five (5) other independent directors, which seek to ensure the powers and duties of the dual role of Mr. Barron are handled responsibly. Furthermore, consistent with Nasdaq listing requirements, the independent directors regularly have the opportunity to meet in executive sessions without Messrs. Barron, Jurvetson and Spiro in attendance.

Mr. Jurvetson also serves as Vice Chairman of the Board of Directors and has a broad range of duties and responsibilities aimed at supporting the chairman of the board of directors and ensuring the effective functioning of our organization.

#### Role in Risk Oversight
The board of directors has extensive involvement in the oversight of risk management related to the Company and its business and will accomplish this oversight through the regular reporting to the board of directors by the audit committee. The audit committee will represent the board of directors by periodically reviewing the Company's accounting, reporting and financial practices, including the integrity of its financial statements, the surveillance of administrative and financial controls and its compliance with legal and regulatory requirements. Through its regular meetings with management, including the finance, legal, internal audit and information technology functions, the audit committee will review and discuss all significant areas of our business and summarize for the board of directors all areas of risk (including cybersecurity) and the appropriate mitigating factors. In addition, the board of directors will receive periodic detailed operating performance reviews from management.

#### Corporate Governance Guidelines
Our board of directors has adopted corporate governance guidelines in accordance with the corporate governance rules of Nasdaq that serve as a flexible framework within which our board of directors and its committees operate. These guidelines cover a number of areas including board membership criteria and director qualifications, director responsibilities, board agenda, meetings of non-management directors, committee responsibilities and assignments, board member access to management and independent advisors, director communications with third parties, director compensation, director orientation and continuing education, evaluation of our chief executive officer and

management succession planning. A copy of our corporate governance guidelines is posted on our website at *www.metals.co* under Investors — Governance — Corporate Governance Overview — Governance Documents.

#### Shareholder Communications to our Board of Directors
Generally, shareholders who have questions or concerns should contact our Investor Relations department at investors@metals.co. However, any shareholders who wish to address questions regarding our business directly with our board of directors, or any individual director, should direct his or her questions in writing to the chairperson of our board of directors at 1111 West Hastings Street, 15<sup>th</sup> Floor, Vancouver, British Columbia V6E 2J3. Communications will be distributed to our board of directors, or to any individual director or directors as appropriate, depending on the facts and circumstances outlined in the communications. Items that are unrelated to the duties and responsibilities of our board of directors may be excluded, such as:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • junk mail and mass mailings;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • resumes and other forms of job inquiries;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • surveys; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • solicitations or advertisements.

In addition, any material that is unduly hostile, threatening, or illegal in nature may be excluded, in which case it will be made available to any outside director upon request.

#### Insider Trading Policy and Prohibition on Hedging
We have an insider trading policy that, among other things, governs the buying and selling of our securities by all of our personnel, including directors, officers, employees and consultants and certain other covered persons. Our policy is designed to prevent violations of insider trading laws by our personnel and to avoid even the appearance of improper conduct in this regard by our personnel. The policy prohibits covered persons from purchasing, selling, or otherwise disposing of our securities while in possession of material non-public information (except in limited circumstances, such as pursuant to a previously established trading plan). The policy includes quarterly and other trading blackouts and sets forth the procedures covered persons must follow before transacting in our securities, including pre-clearance of all transactions by certain persons, as well as members of their households.

Although we have not adopted an insider trading policy governing our purchase, sale, and/or other disposition of our securities, as part of the oversight of risk, our board of directors, or one or more of its committees, approves any transaction, plan or arrangement by or with us with respect to our securities on a case-by-case basis, and as part of their procedures to review and approve any such transaction, plan or arrangement, our board of directors or committee consults with legal counsel as needed to help ensure our compliance with applicable insider trading laws, rules and regulations, and listing standards.

In addition, our insider trading policy explicitly prohibits the engagement of our employees, contractors, directors and officers to engage in short-term or speculative transactions involving our securities, which includes:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • trading in our securities on a short-term basis (any of our common shares purchased in the open market must be held for a minimum of six months and ideally longer);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • purchasing of financial instruments (including prepaid variable forward contracts, equity swaps, puts, calls, straddles, collars and exchange funds) that are designed to hedge or offset any decrease in the market value of our equity securities and entering into other transactions with the same economic effect, including short sales;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • borrowing or other arrangements involving pledge of securities; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • selling a security future that establishes a position that increases in value as the value of the underlying equity security decreases.

[**TABLE OF CONTENTS**](#TOC)

A copy of our insider trading policy is filed as an exhibit to our Annual Report on Form 10-K for the year ended December 31, 2025 as filed with the SEC.

#### Stock Ownership Guidelines
We have stock ownership guidelines for non-employee directors and our senior executive officers. Our stock ownership guidelines require that within five years of their hire date (or date of promotion to executive officer), non-employee directors and executive officers acquire and maintain ownership of our common shares at different multiples of their annual board retainer or annual base salary depending upon position. Common shares owned include shares owned directly, shares owned indirectly (e.g., by a spouse or trust), shares represented by amounts invested in a 401(k) plan or deferred compensation plan we maintain, time-vested restricted stock, restricted stock units or phantom stock, but exclude unexercised options and unearned performance shares. Each non-employee director has an ownership requirement of two (2) times their annual retainer. The Chief Executive Officer has an ownership requirement of three (3) times base salary. The Chief Financial Officer has an ownership requirement of one (1) time base salary. The remaining officers covered by the policy have ownership requirements of one half (1/2) times their base salary.

As of December 31, 2025, all of our non-employee directors and each executive officer covered by the policy met their ownership thresholds or are within the initial five-year grace period to meet their ownership threshold.

Our board of directors may revoke or modify these guidelines at any time.

#### Clawback Policy
We believe that it is in our best interests and that of our shareholders to create and maintain a culture that emphasizes integrity and accountability and therefore, in compliance with SEC and Nasdaq rules, we adopted a clawback policy that is administered by the compensation committee and which provides for the recoupment of certain executive compensation in the event of an accounting restatement resulting from material noncompliance with financial reporting requirements under the federal securities laws. Our clawback policy provides for the mandatory reimbursement or recovery, from current and former officers, of excess incentive-based compensation that was erroneously awarded during the three years preceding the date that we are required to prepare certain accounting restatements of our financial statements.

#### EXECUTIVE OFFICER AND DIRECTOR COMPENSATION

#### Introduction
This section provides an overview of our executive compensation programs, including a narrative description of the material factors necessary to understand the information disclosed in the summary compensation table below.

We are eligible to use the requirements of a "smaller reporting company" within the meaning of the Securities Exchange Act of 1934, as amended, for purposes of the SEC's executive compensation disclosure rules. Accordingly, we are required to provide a Summary Compensation Table and an Outstanding Equity Awards at Fiscal Year End Table, as well as limited disclosures regarding executive compensation for our last two completed fiscal years. Further, our reporting obligations extend only to the following "Named Executive Officers" ("NEOs"), which are the individuals who served as principal executive officer and the next two most highly compensated executive officers for the year ended December 31, 2025. As of December 31, 2025, our NEOs were:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Gerard Barron, Chief Executive Officer;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Craig Shesky, Chief Financial Officer; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Erika Ilves, Chief Strategy Officer

In 2024, we entered into new compensation arrangements for Gerard Barron, our Chief Executive Officer and Chairman, which were approved by our shareholders on an advisory basis at our 2024 annual meeting of shareholders held on May 30, 2024. These 2024 compensation arrangements directly factored into Mr. Barron's 2025 compensation.

Our current executive compensation plan for our other NEOs has been in place since September 9, 2021 and is the ongoing compensation program for these NEOs post-Business Combination.

As discussed in more detail below, in 2025, our executive compensation program was designed to provide our NEOs with meaningful incentives and rewards, while effectively balancing the short-term and long-term interests of our shareholders with our ability to attract and retain talented executives. The compensation committee of our board of directors has the primary responsibility for establishing our executive compensation philosophy and determining the specific components and levels of each NEO's compensation. Our executive compensation program is based on four guiding principles. We have created a compensation program that combines short-term and long-term components, cash, equity, fixed and performance- based contingent payments, in the proportions that we believe achieve these four guiding principles:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • enhance shareholder value by aligning the financial interests of our NEOs with those of our shareholders;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • enable us to attract, motivate and retain the people needed to define and lead our industry;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • integrate compensation closely with the achievement of our business and performance objectives; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • reward the individual performance that contributes to our short-term and long-term success.

The compensation committee utilized and relied significantly on a competitive market analysis when determining the size, components and mix of our NEOs' compensation packages.

As discussed in more detail below, our NEOs' target annual compensation generally consists of three principal components: (a) base salary, (b) an annual performance award under our Short-Term Incentive Plan ("STIP") and (c) long-term equity incentive compensation under our Long-Term Incentive Plan ("LTIP"). The base salary component is primarily designed to provide a predictable level of financial stability. The STIP is designed to reward the achievement of annual goals that are aligned with our strategic plan. The base salary and STIP are referred to as the cash component of the compensation plan. The LTIP is the equity compensation component and is primarily designed to incentivize and retain our executives over a multi-year period and to reward the achievement of our long-term financial and strategic objectives.

[**TABLE OF CONTENTS**](#TOC)

#### Elements of Compensation for Our NEOs
Our executive compensation program consists of three principal components: base salary, STIP, and LTIP. The LTIP consists primarily of restricted share units ("RSUs") that vest over time based on continued employment and, in some cases, the achievement of performance and market goals.

#### Key Components of Our 2025 Compensation Plans for Our NEOs

| | | | |
|:---|:---|:---|:---|
| **Compensation <br> Element** | **Primary Purpose**  | **Performance <br> Period** | **Details**  |

| Short-Term Incentive Plan (STIP) | Reinforce and drive short-term priorities and business results | 1 year | Target award based on a percentage of salary. |
|  | Recognize and reward corporate and individual performance |  | Awards may be earned from 0% to 100% of target based on achievement of pre- determined corporate short-term objectives that are aligned with our strategic plan as well as individual performance. <br> Awards are paid in cash upon the completion of the fiscal year; however, at the election of the Company, 2024 STIP awards were paid in immediately-vested RSUs to conserve operating cash.  |

[**TABLE OF CONTENTS**](#TOC)

#### Equity Compensation for Our NEOs
We use long-term equity-based compensation to incentivize and retain our executive officers by linking their awards to the achievement of our long-term strategic goals. We typically award long-term equity-based compensation with restricted share units that vest over time so long as the executive remains employed with the Company.

The compensation committee determines the size of equity award grants after considering the following factors:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the competitive equity compensation practices for comparable positions identified in the applicable market analysis;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the executive's level of responsibility and duties;

The compensation committee does not take into consideration an executive's aggregate equity holdings or equity carrying value in determining annual long-term equity incentive awards.

In March 2025, our compensation committee granted equity awards under our LTIP. Mr. Barron received 1,598,070 RSUs and each of Mr. Shesky and Ms. Ilves received 625,125 RSUs.

In July 2025, our compensation committee approved special retention RSU awards to Mr. Shesky and Ms. Ilves to support the Company's transition from the pre-licensure phase to commercial operations. These awards were made in September 2025. In approving these awards, the compensation committee considered the critical roles, experience and institutional knowledge of the NEOs, as well as the importance of retaining the leadership team through key milestones. The structure and size of the awards were informed by an analysis conducted by FW Cook, the independent compensation consulting firm engaged by the compensation committee to provide competitive market data and advice on compensation program design. Mr. Shesky and Ms. Ilves each received 2,000,000 RSUs that vest, subject to each continuing to be employed by us through September 1, 2029 (the "Retention Date"), as follows: (i) 50% upon the trailing 30-day average closing price of the common shares (the "Average Share Price") reaching $10.00 on or before April 16, 2029, and (ii) 50% upon the Average Share Price reaching $12.50 on or before April 16, 2029. Common shares received upon settlement of the RSUs may not be sold or otherwise transferred prior to the Retention Date.

In April 2026, our compensation committee granted equity awards to our NEOs under the LTIP. Mr. Barron received 816,327 RSUs and each of Mr. Shesky and Ms. Ilves received 453,515 RSUs.

#### Compensation of Our Chief Executive Officer and Chairman
We entered into an employment agreement with Mr. Barron in 2018 prior to the closing of the Business Combination and our becoming a publicly-traded company. In light of the lack of substantial updates in Mr. Barron's compensation since that time, the developments in our business and the board of directors' belief that the compensation of our Chief Executive Officer is critical to align the interests of our Chief Executive Officer with that of our shareholders, our board of directors and its compensation committee engaged in extensive discussions over a significant length of time regarding updates to Mr. Barron's employment terms. Upon the conclusion of these discussions, the compensation committee and the board of directors approved a new compensation package for Mr. Barron and we entered into a new employment agreement with Mr. Barron on April 16, 2024 (the "2024 Barron Employment Agreement"). Throughout this process, the compensation committee consulted with FW Cook, its independent compensation consultant, and its outside legal counsel and also conferred with Mr. Barron, provided that Mr. Barron was not present during any voting or deliberations on the new compensation

package or the 2024 Barron Employment Agreement. Our shareholders approved the new compensation arrangements on an advisory basis at our 2024 annual meeting of shareholders held on May 30, 2024.

The principal economic terms of the 2024 Barron Employment Agreement are summarized below and carried over into Mr. Barron's 2025 compensation.

#### Cash Compensation
*Annual Salary* 

Mr. Barron receives an annual base salary of $750,000, which shall be reviewed annually by our board of directors

*Annual Bonus* 

Mr. Barron is eligible for an annual cash bonus, based on achievement of individual performance objectives and achievement of certain company financial results as established by our board of directors, with the target amount set at 75% of his base salary. Mr. Barron received a cash bonus under the STIP of $750,000 for 2025.

*Retirement Account Contributions* 

We will provide Mr. Barron with an additional amount equal to 10% of his base salary per year to be contributed to Mr. Barron's retirement plan (the "Retirement Benefit").

#### Equity Compensation
*Signing RSUs* 

In April 2024, Mr. Barron received a one-time signing bonus award of performance-based restricted stock units for up to 20,000,000 of our common shares, based on the achievement of stock price goals (the "Signing RSUs").

The Signing RSUs vest upon our common shares achieving the following closing prices per share, based on the trailing 30-day average price (the "Closing Price"), on or prior to April 16, 2029, subject to Mr. Barron's continued service with us on the applicable vesting date: one-third of the Signing RSUs vested upon achievement of a Closing Price of $7.50 (achieved in 2025); one-third of the Signing RSUs vest upon achievement of a Closing Price of $10.00; and one-third of the Signing RSUs vest upon achievement of a Closing Price of $12.50 (each subject to equitable adjustment for any stock splits, combinations, reclassifications, stock dividends and the like). Any Signing RSUs that do not vest on or prior to April 16, 2029 will be forfeited.

Mr. Barron shall not be permitted to sell any shares settled upon the vesting of the Signing RSUs until April 16, 2029, at which point all such vested shares shall be freely tradeable by Mr. Barron at his full discretion, subject to compliance with our Insider Trading Policy and applicable laws.

*Participation in Annual LTIP* 

Mr. Barron is also eligible to be considered for annual equity awards under our LTIP at the discretion of the board of directors. See above for information on Mr. Barron's LTIP award in 2025.

#### Severance and Change of Control Payments
*Severance* 

In the event that Mr. Barron's employment is terminated without Cause (as defined in the 2024 Barron Employment Agreement) or if Mr. Barron resigns for Good Reason (as defined in the 2024 Barron Employment Agreement), or in the event that the 2024 Barron Employment Agreement is not renewed by us at the end of any one-year term, Mr. Barron will receive: 18 months of base salary (including the

#### Other Compensation and Benefits
We believe that establishing a competitive benefit package consistent with companies with which we compete for employees is an important factor in attracting and retaining talented employees. Thus, we provide our NEOs with employee benefits on the same basis as offered to our full-time non-executive employees, including health and dental benefits and a 401(k) plan (or equivalent as determined by employee's jurisdiction of employment).

#### Employment Arrangements
We have employment agreements with our NEOs, the material terms of which are described below. In addition, each NEO has agreed to non-competition, non-solicitation and non-interference covenants that apply during the term of employment and for 12 months thereafter, as well as assignment of intellectual property and confidentiality obligations, each as set forth in his or her respective employment agreement.

Mr. Barron began his current position as our Chief Executive Officer in January 2018 with DeepGreen. Mr. Shesky began his current position as our Chief Financial Officer in May 2021 with DeepGreen. Ms. Ilves began her current position as our Chief Strategy Officer in September 2021 and held previous positions with DeepGreen before the closing of the Business Combination.

Under the 2024 Barron Employment Agreement, Mr. Barron will also be eligible for an annual cash bonus, based on achievement of individual performance objectives and achievement of certain company financial results as established by our board of directors, with the target amount of his annual bonus set at 75% of his base salary, payable at the discretion of the board of directors. In addition, in connection with entering into the 2024 Barron Employment Agreement, we granted Mr. Barron a one-time signing bonus award of performance-based restricted stock units (the "Signing RSUs") with respect to 20,000,000 of our common shares. The Signing RSUs vest upon our common shares achieving specified closing prices per share, based on the trailing 30-day average price (the "Closing Price"), on or prior to April 16, 2029, subject to Mr. Barron's continued service with us on the applicable vesting date. One-third of the Signing RSUs vested upon achievement of a Closing Price of $7.50 in 2025.

#### Relationship Between Compensation Actually Paid and Company Performance
*Overview* 

Our executive compensation program was designed to provide our NEOs with meaningful incentives and rewards, while effectively balancing the short-term and long-term interests of our shareholders with our ability to attract and retain talented executives. As a development-stage enterprise that has not yet achieved commercial production and has not generated any revenue, our compensation committee and board of directors have not looked to net income (loss) or total shareholder return as performance measures considered under our executive compensation program. Instead, our compensation committee and board of directors have implemented a compensation program that we believe achieves four guiding principles of (a) enhancing shareholder value, (b) attracting, motivating and retaining our executives, (c) integrating compensation with our business and performance objectives and (d) rewarding individual performance that contributes to our short-term and long-term success. As a result, we do not specifically focus our compensation decisions on compensation actually paid (as computed in accordance with SEC rules) or how these amounts compare to net income (loss) or total shareholder return in any particular period. See the disclosures elsewhere under "*Executive Officer and Director Compensation*" and under "*Proposal No. 4 — Non-Binding Advisory Vote on Approval of Executive Compensation as Disclosed in this Proxy Statement*" for additional information about our compensation program.

In addition, in 2024, our board of directors, upon recommendation of our compensation committee, approved a new and comprehensive compensation package for our PEO, which was approved by our shareholders on an advisory basis at the 2024 annual meeting of shareholders. The board of directors concluded that this compensation package was critical to align the interests of our PEO with those of our shareholders, and to ensure our PEO's retention and continued leadership as we pursue the creation of a new and transformative industry in deep-sea mineral exploration and directly factored into our PEO's 2024 and 2025 compensation. A key component of this new compensation package is the one-time award of 20,000,000 market-based RSUs that vest only upon achievement of stock price targets, which represented substantial premiums over our share price at the time, which we believe aligns our PEO's compensation with the creation of shareholder value over the five-year performance period.

*Compensation Actually Paid and Net Loss/Total Shareholder Return* 

Our net loss for the year ended December 31, 2025 was $319.8 million, a $237.9 million, or 290.5%, increase from our net loss for the year ended December 31, 2024 of $81.9 million. The increase in net loss over these periods reflects the significant increase in the royalty liability on our NORI project and our ongoing investment in exploration, technology development, and regulatory advancement activities necessary to position us for potential commercial production. Total shareholder return increased 1.82% during the period from December 29, 2023 to December 31, 2024 (with $100 invested on December 29, 2023 having a value of $101.82 at December 31, 2024), but increased substantially to 460.91% during the period from December 29, 2023 to December 31, 2025 (with $100 invested on December 29, 2023 having a value of $560.91 at December 31, 2025). We believe this return reflects the achievements we have made to prepare for potential commercial production.

The compensation actually paid to our PEO totaled $99,797,809 in 2025, which was a $85,861,411, or 616.09%, increase from the compensation actually paid to our PEO in 2024 of $13,936,398. The increase primarily reflects the impacts of the 2024 shareholder approved compensation arrangements and the significant increase in our share price in 2025. The average compensation actually paid to our Non-PEO NEOs totaled $20,859,572 in 2025, which was $19,302,640, or 1,239.79%, increase from the average compensation actually paid to our Non-PEO NEOs in 2024 of $1,556,932. The increase primarily reflects the impacts of the significant increase in our share price in 2025 and the special retention RSUs granted to our Non-PEO NEOs in 2025.

#### Stock Compensation Plans and Awards

#### DeepGreen Plan
As a consequence of the Business Combination, we adopted and assumed the DeepGreen Metals Inc. Stock Option Plan, as amended (the "DeepGreen Plan"), and each option to purchase DeepGreen common shares, whether vested or unvested, that was outstanding immediately prior to the time the arrangement pursuant to the court-approved plan of arrangement became effective (the "Effective Time") was assumed by us and became an option (vested or unvested, as applicable) to purchase a number of our common shares equal to the number of DeepGreen common shares subject to such option immediately prior to the Effective Time multiplied by the Per Share Consideration, rounded down to the nearest whole number of shares, at an exercise price per share equal to the exercise price per share of such option immediately prior to the Effective Time divided by the Per Share Consideration, rounded up to the nearest whole cent, as well as a certain number of Class A through H Special Shares. No further awards will be granted out of the DeepGreen Plan.

The DeepGreen Board adopted, and DeepGreen's shareholders approved, the DeepGreen Plan on September 17, 2013. The DeepGreen Plan has been periodically amended, most notably: on July 23, 2018, in order to increase the number of shares of DeepGreen common shares available for issuance pursuant to the DeepGreen Plan to a maximum of 20% of the issued and outstanding common shares, and on May 16, 2019 in order to clarify the application with respect to certain provisions of employee scheme legislation in Australia. The DeepGreen Plan permits the grant of options of DeepGreen's common shares, as defined by the DeepGreen Plan (the "Options"). Options may be granted only to (i) a *bona fide* director, senior officer, employee of DeepGreen, (ii) a company that is wholly-owned by any of the foregoing, or (iii) a consultant of DeepGreen. The board of directors, in its sole discretion, may accelerate the vesting of any unexercised options in accordance with the change of control provisions set forth in the DeepGreen Plan.

The board of directors is authorized to administer the DeepGreen Plan. In addition, consistent with the terms of the DeepGreen Plan, the board of directors may determine the number of shares issuable for the exercise of each Option, the Option Price, as defined by the DeepGreen Plan, and the times when any such Options will be granted, exercisable and expire under the DeepGreen Plan. No further awards will be granted pursuant to the DeepGreen Plan.

Upon any time when an Option granted under the DeepGreen Plan remains unexercised with respect to any common shares and a transaction is proposed that the majority of the board of directors determines

------

[**TABLE OF CONTENTS**](#TOC)

is reasonably likely to be considered a Change of Control Event, as defined by the DeepGreen Plan (a "Change of Control Event"), then the board of directors, in its sole discretion, may require that: (i) DeepGreen accelerate the vesting of the Option and the time for the fulfillment of any conditions or restrictions on such vesting; (ii) the Option granted under the DeepGreen Plan be exercised (whether or not such Option has vested at any time up to and including (but not after)) the effective time of the Change of Control Event, and any Options not exercised by the effective time of the Change of Control Event will be deemed to have expired; (iii) the Option granted under the DeepGreen Plan, if acceptable by the holder, be cancelled by DeepGreen for a cash payment equal to the difference between (y) the closing price of such shares on a trading day that is a determined number of days prior to the effective time of the Change of Control Event and (z) the price of the Option; or (iv) the Option granted under the DeepGreen Plan be exchanged for an Option to acquire the number of securities as are distributed to the securityholders of DeepGreen equal to (y) the exchange ratio of the shares multiplied by (z) the number of shares subject to such Option immediately prior to the effective time of the Change of Control Event, provided that any such replacement Option survives for a period of not less than one year from the effective time of the Change of Control Event, regardless of the continuing directorship, officership or employment of the holder.

The board of directors may amend, suspend, or terminate the DeepGreen Plan at any time. The board of directors must obtain shareholder approval of any plan amendment to the extent required by the DeepGreen Plan.

#### TMC 2021 Incentive Equity Plan
*Eligibility* 

The TMC the metals company Inc. 2021 Incentive Equity Plan (the "TMC Incentive Equity Plan") allows for grants, under the direction of the board of directors or compensation committee, as the plan administrator, of stock options, stock appreciation rights, restricted stock awards, stock awards, restricted share units and other stock or equity-related cash-based awards to employees, consultants and non-employee directors who, in the opinion of the plan administrator, are in a position to make a significant contribution to our long-term success. All of our employees, non-employee directors and consultants and our affiliates will be eligible to participate in the TMC Incentive Equity Plan.

*Shares Available for Issuance* 

The TMC Incentive Equity Plan provides for the issuance of up to an aggregate of 127,181,509 common shares, which number includes 16,918,653 shares added to the plan in January 2026 pursuant to the plan's evergreen provision, provided that 2,243,853 of the common shares available under the Plan will only be available to our non-employee directors. As of April 2, 2026, there were 40,648,858 common shares underlying restricted stock units outstanding and 11,023,333 common shares underlying outstanding options, and 28,105,647 common shares remained available for future awards under this plan. Notwithstanding the foregoing, the number of future shares that may be issued will increase automatically on the first day of each fiscal year during the period beginning with fiscal year 2022 and ending on the tenth anniversary of the closing of the Business Combination, equal to the lesser of (a) 4% of the number of outstanding Common Shares on such date, and (b) an amount determined by the plan administrator.

Generally, common shares reserved for awards under the TMC Incentive Equity Plan that lapse or are forfeited or cancelled will be added back to the share reserve available for future awards. However, shares delivered to or withheld to pay withholding taxes or any applicable exercise price will not be available for issuance under the TMC Incentive Equity Plan. In addition, any shares repurchased on the open market using exercise price proceeds will not be available for issuance under the TMC Incentive Equity Plan.

The aggregate grant date fair value of shares granted to any non-employee director under the TMC Incentive Equity Plan and any other cash compensation paid to any non-employee director for director services in any calendar year may not exceed $500,000; increased to $750,000 in the year in which such non-employee director initially joins the board of directors. These $500,000 and $750,000 limitations are

------

[**TABLE OF CONTENTS**](#TOC)

determined without regard to amounts paid to a non-employee director during any period in which such individual was an employee or consultant (other than grants of awards paid for service in their capacity as a non-employee director), and any severance and other payments, such as consulting fees, paid to a non-employee director for such director's prior or current service to us or an affiliate of ours other than serving as a director, shall not be taken into account in applying such limitations.

*Stock Options* 

The terms and conditions of our ability to grant stock options are governed by the TMC Incentive Equity Plan. Notably, we have established a sub-plan to the TMC Incentive Equity Plan (the "U.S. Sub- Plan") for the purpose of granting stock options to employees who are residents of the United States or who are or may become subject to U.S. tax. Stock options granted under the U.S. Sub-Plan may either be incentive stock options, which are intended to satisfy the requirements of Section 422 of the U.S. Internal Revenue Code of 1986, as amended, or non-qualified stock options. Incentive stock options may be granted to our and our affiliates' employees, and the aggregate fair market value of a common share determined at the time of grant with respect to incentive stock options that are exercisable for the first time by a participant during any calendar year may not exceed $100,000. Non-qualified options may be granted to our employees, non-employee directors and consultants and our affiliates. If an incentive stock option is granted to an individual who owns 10% or less of the combined voting power of all classes of our stock or our affiliate, the exercise price of the stock option may not be less than 100% of the fair market value of the common shares on the date of grant, and the term of the stock option may not be longer than ten (10) years. If an incentive stock option is granted to an individual who owns more than 10% of the combined voting power of all classes of our stock of or our affiliate, the exercise price of the stock option may not be less than 110% of the fair market value of the common shares on the date of grant, and the term of the stock option may not be longer than five years.

Award agreements for stock options include rules for exercise of the stock options after termination of service. Options may not be exercised unless they are vested, and no option may be exercised after the end of the term set forth in the award agreement. Generally, stock options will be exercisable for three months after termination of service for any reason other than death or total and permanent disability, and for one (1) year after termination of service on account of death or total and permanent disability but will not be exercisable if the termination of service was due to cause.

*Restricted Stock* 

Restricted stock that is subject to restrictions, including a prohibition against transfer and a substantial risk of forfeiture, until the end of a "restricted period" during which the grantee must satisfy certain time or performance-based vesting conditions. If the grantee does not satisfy the vesting conditions by the end of the restricted period, the restricted stock is forfeited. During the restricted period, the holder of restricted stock has the rights and privileges of a regular shareholder, except that generally dividend equivalents may accrue but will not be paid during the restricted period, and the restrictions set forth in the applicable award agreement apply. For example, the holder of restricted stock may vote the restricted shares, but he or she may not sell the shares until the restrictions are lifted.

*Restricted Share Units* 

Restricted share units vest in accordance with terms and conditions established by the plan administrator and when the applicable restrictions lapse, the grantee will be entitled to receive a payout in cash, shares or a combination thereof based on the number of restricted share units as specified in the award agreement. Dividend equivalents may accrue but will not be paid prior to and only to the extent that the restricted stock unit award vests. The holder of restricted share units does not have the rights and privileges of a regular shareholder, including the ability to vote the restricted share units.

*Other Share-Based Awards and Performance-Based Awards* 

The TMC Incentive Equity Plan also authorizes the grant of other types of share-based compensation including but not limited to share appreciation rights and unrestricted share awards. The plan administrator may award such share-based awards subject to such conditions and restrictions as it may determine. We

------

[**TABLE OF CONTENTS**](#TOC)

may grant an award conditioned on satisfaction of certain performance criteria. Such performance-based awards also include restricted shares and restricted share units.

Any dividends or dividend equivalents payable or credited to a participant with respect to any unvested performance-based award will be subject to the same performance goals as the shares or units underlying the performance-based award.

*Plan Administration* 

In accordance with the terms of the TMC Incentive Equity Plan, the board of directors may administer the TMC Incentive Equity Plan or authorize the compensation committee to administer the TMC Incentive Equity Plan. The compensation committee may delegate part of its authority and powers under the TMC Incentive Equity Plan to one or more of our directors and/or officers, but only the compensation committee can make awards to participants who are subject to the reporting and other requirements of Section 16 of the Securities Exchange Act of 1934, as amended. In accordance with the provisions of the TMC Incentive Equity Plan, the plan administrator determines the terms of awards, including, which employees, directors and consultants will be granted awards, the number of shares subject to each award, the vesting provisions of each award, the termination or cancellation provisions applicable to awards, and all other terms and conditions upon which each award may be granted in accordance with the TMC Incentive Equity Plan.

In addition, the plan administrator may, in its discretion, amend any term or condition of an outstanding award provided (i) such term or condition as amended is not prohibited by the TMC Incentive Equity Plan and does not require shareholder approval under the rules of Nasdaq, and (ii) any such amendment will be made only with the consent of the participant to whom such award was made, if the amendment is adverse to the participant unless such amendment is required by applicable law or necessary to preserve the economic value of such award.

*Stock Dividends and Stock Splits* 

If the common shares are subdivided or combined into a greater or smaller number of shares or if we issue any common shares as a stock dividend, the number of common shares deliverable upon exercise of an option issued or upon issuance of an award will be appropriately increased or decreased proportionately, and appropriate adjustments will be made in the exercise price per share of stock options or purchase price, if any, and performance goals applicable to performance-based awards, if any, to reflect such subdivision, combination or stock dividend.

*Corporate Transactions* 

Upon a merger or other reorganization event, the plan administrator or the board of directors of any entity assuming our obligations may take any one or more of the following actions pursuant to the TMC Incentive Equity Plan, as to some or all outstanding options and awards:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • provide that all outstanding options will be assumed or substituted by the successor corporation;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • upon written notice to a participant, provide that the participant's unexercised options must be exercised within a specified number of days of the date of such notice, at the end of which period such unexercised options will terminate;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • in the event of a merger pursuant to which holders of common shares will receive a cash payment for each share surrendered in the merger, make or provide for a cash payment to option holder participants equal to the difference between the merger price times the number of common shares subject to such outstanding options, and the aggregate exercise price of all such outstanding options, in exchange for the termination of such options;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • with respect to other stock awards, provide that outstanding awards will be assumed or substituted by the successor corporation;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • with respect to stock awards, and in lieu of any of the foregoing, provide that, upon consummation of the transaction, each outstanding stock award will be terminated in exchange for payment of an

------

[**TABLE OF CONTENTS**](#TOC)

amount equal to the consideration payable upon consummation of such transaction to a holder of the number of common shares comprising such award (to the extent such stock grant or award is no longer subject to any forfeiture or repurchase rights then in effect or, at the discretion of the board of directors or an authorized committee, all forfeiture and repurchase rights being waived upon such transaction); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • upon consummation of a Corporate Transaction, to the extent not assumed or substituted by the successor or cashed out, the outstanding awards will terminate.

*Amendment and Termination* 

The TMC Incentive Equity Plan may be amended by our shareholders. It may also be amended by the board of directors or the compensation committee, provided that any amendment which is of a scope that requires shareholder approval as required by (i) the rules of Nasdaq or (ii) for any other reason, is subject to obtaining such shareholder approval. However, no such action may adversely affect any rights under any outstanding award without the holder's consent unless such amendment is required by applicable law or necessary to preserve the economic value of such award.

*Duration of Plan* 

The TMC Incentive Equity Plan will expire by its terms in April 2031.

#### Policies and Practices Related to the Grant of Certain Equity Awards
LTIP and other incentive awards were made in March in 2025 and April in 2026. The compensation committee, however, anticipates granting LTIP awards generally in February of each year going forward. The compensation committee and the board of directors do not time the grant of equity compensation with regards to the release of material nonpublic information, whether or not that information may favorably or unfavorably impact the price of our common shares. Similarly, we do not time the release of material nonpublic information based on equity award grant dates. Equity awards for the executive officers, including our Chief Executive Officer, are approved by the compensation committee. We did not grant options to any of our executive officers during 2025.

#### Director Compensation
On September 9, 2021, we adopted a non-employee director compensation policy. Pursuant to the policy, the annual cash retainer for non-employee directors is $90,000. Annual cash retainers for committee membership are as follows:

---

| | |
|:---|:---|
| **Position**  | **Retainer**  |
| Lead independent director  | $30000 |
| Audit committee chairperson  | $22500 |
| Audit committee member  | $7500 |
| Compensation committee chairperson  | $15000 |
| Compensation committee member  | $5000 |
| Nominating and corporate governance committee chairperson  | $15000 |
| Nominating and corporate governance committee member  | $5000 |
| Sustainability and innovation committee chairperson  | $15000 |
| Sustainability and innovation committee member  | $5000 |

---

These fees are payable in arrears in quarterly installments as soon as practicable following the last business day of each fiscal quarter, provided that the amount of such payment will be prorated for any portion of such quarter that a director is not serving on the board of directors, on such committee or in such position. In the fourth quarter of 2024, in an effort to conserve cash, a majority of our directors approved a modification to the form of payment of their annual cash retainers and elected to receive immediately vesting RSUs in lieu of cash, which elections remain in place. The number of RSUs granted

------

[**TABLE OF CONTENTS**](#TOC)

is determined by dividing the amount of deferred cash compensation by the closing price of our common shares on the date of the annual meeting. RSUs in respect of deferred cash compensation for 2024 were granted on the first day following the 2025 annual meeting. RSUs in respect of deferred cash compensation for 2025 are expected to be granted on the first day following the upcoming Annual Meeting.

Non-employee directors are also reimbursed for reasonable out-of-pocket business expenses incurred in connection with attending meetings of the board of directors and any committee of the board of directors on which they serve and in connection with other business related to the board of directors. Directors may also be reimbursed for reasonable out-of-pocket business expenses in accordance with our travel and other expense policies, as may be in effect from time to time.

**Initial Grant —** In addition, we grant to new non-employee directors upon their initial election to the board of directors a number of RSUs (each RSU relating to one share of common shares), having an aggregate fair market value equal to $100,000, determined by dividing (A) $100,000 by (B) the closing price of the common shares on Nasdaq on the date of the grant (rounded down to the nearest whole share), on the first business day after the date that the non-employee director is first appointed or elected to the board of directors. Each of these grants shall vest in equal annual installments over three years from the date of the grant, subject to the non-employee director's continued service as a director on the applicable vesting dates.

**Annual Grant —** We also grant each non-employee director annually a number of RSUs (each RSU relating to one common share), having an aggregate fair market value equal to $100,000, determined by dividing (A) $100,000 by (B) the closing price of the common shares on the Nasdaq on the date of the grant (rounded down to the nearest whole share), each year on the first business day after our annual meeting of shareholders (the "Annual Grant"); provided, however, that if there has been no annual meeting of shareholders held by the first business day of the third fiscal quarter, we make the Annual Grant to each non-employee director on the first business day of the third fiscal quarter of such year.

Pursuant to the terms of their individual consulting agreements, Messrs. Jurvetson, Hess and Spiro waived their rights to any compensation they may have been entitled to for serving on the board of directors, including under our non-employee director compensation policy.

The table below summarizes the compensation of each person serving as a non-employee director of TMC for the fiscal year ended December 31, 2025. Gerard Barron, our Chief Executive Officer, did not receive any additional compensation for his service as a director of TMC in 2025. The compensation of Mr. Barron as a NEO is set forth above under "*Summary Compensation Table*." See also "*Certain Relationships and Related Person Transactions*" below for additional information about other transactions between us and our directors.

In addition to the director and executive officer compensation arrangements discussed above in "*Executive Officer and Director Compensation*," since January 1, 2024, we have engaged in the following transactions in which the amount involved exceeded $120,000 and in which any director, executive officer or holder of more than 5% of our voting securities, whom we refer to as our principal shareholders, or affiliates or immediate family members of our directors, executive officers and principal shareholders, had or will have a material interest. We believe that all of these transactions were on terms as favorable as could have been obtained from unrelated third parties.

#### 2023 Registered Direct Offering
On August 14, 2023, we entered into a securities purchase agreement with certain investors, pursuant to which we agreed to sell and issue, in a registered direct offering (the "Registered Direct Offering") 12,461,540 of our common shares and issue Class A warrants to purchase 6,230,770 common shares for expected gross proceeds to us of $24.9 million and expected net proceeds to us of $23.6 million, after deducting underwriting discounts and commissions and other offering expenses payable by us. The common share and the accompanying Class A warrant to purchase 0.5 of a common share were sold at a price of $2.00 per unit. The exercise price of the Class A warrants is $3.00, subject to adjustment as provided in the warrant agreement. The Registered Direct Offering initially closed in August 2023, with the final receipt of gross proceeds received in January 2024.

ERAS Capital LLC, the family fund of our director, Andrei Karkar, agreed to purchase 5,000,000 common shares and accompanying Class A warrants to purchase 2,500,000 of our common shares for a total purchase price of $10 million, the last of which was paid in 2024. In addition, Allseas agreed to purchase 3,500,000 of our common shares and accompanying Class A warrants to purchase 1,750,000 common shares for a total purchase price of $7 million which was paid in 2023. Gerard Barron, Craig Shesky, and other members of the Company's board of directors also agreed to purchase securities in the Registered Offering during 2023.

#### Credit Facility with ERAS Capital LLC and Gerard Barron
On March 22, 2024, we entered into an Unsecured Credit Facility (the "2024 Credit Facility") with Gerard Barron and ERAS Capital LLC, the family fund of our director, Andrei Karkar (collectively, the "2024 Lenders"), pursuant to which we may borrow from the 2024 Lenders up to $20,000,000 in the aggregate ($10,000,000 from each of the 2024 Lenders), from time to time, subject to certain conditions. All amounts drawn under the 2024 Credit Facility will bear interest at the 6-month Secured Overnight Funding Rate (SOFR), 180-day average plus 4.0% per annum payable in cash semi-annually (or plus 5% if paid-in-kind at maturity, at our election) on the first business day of each of June and January. We will pay an underutilization fee equal to 4.0% per annum payable semi-annually for any amounts that remain undrawn under the 2024 Credit Facility. We have the right to pre-pay the entire amount outstanding under the 2024 Credit Facility at any time, before the 2024 Credit Facility's maturity of September 22, 2025. The 2024 Credit Facility also contains customary events of default. The 2024 Credit Facility will terminate automatically if we or any of our subsidiaries raise at least $50,000,000 in the aggregate (i) through the issuance of any of our or our subsidiaries' debt or equity securities, or (ii) in prepayments under an off-take agreement or similar commercial agreement. As of the date of this Proxy Statement, the Company has drawn $2.5 million from the 2024 Credit Facility. On November 14, 2024, we entered into the Second Amendment to the 2024 Credit Facility, to increase the borrowing limit to $38 million in the aggregate ($19 million from each of the 2024 Lenders) and to extend the maturity of the 2024 Credit Facility to December 31, 2025. On March 26, 2025, we entered into the Third Amendment to the 2024 Credit Facility with the 2024 Lenders, to, among other things, increase the borrowing limit to $44 million in the aggregate ($22 million from each of the 2024 Lenders) and extend the maturity of the 2024 Credit Facility to June 30, 2026. The Third Amendment also provides that the 2024 Lenders may extend the term of the 2024 Credit Facility by up to two additional one-year periods (until June 30, 2028 at the latest) and that the 2024 Lenders may terminate the 2024 Credit Facility upon certain company financings. On March 25, 2026, 2024 Lenders extended the maturity date of the 2024 Credit Facility by one year to June 30, 2027.

#### Stephen Jurvetson Consulting Agreement
On April 9, 2024, we entered into a consulting agreement with Mr. Jurvetson. The consulting agreement provides, among other things, that Mr. Jurvetson will serve as a special advisor to our Chief Executive Officer for a term of five years. As the sole compensation for his advisory services, Mr. Jurvetson was granted a stock option to purchase 3,440,000 common shares, with an exercise price equal to $1.71 and expiry period of seven years. The stock options were issued under the TMC Incentive Equity Plan and shall vest in three equal annual installments on the first, second and third anniversary of the date of grant of the options provided that Mr. Jurvetson is still providing services to us at such time. Pursuant to the terms of the consulting agreement, Mr. Jurvetson waived his right to any compensation he may have been entitled to for serving on the board of directors, including under our non-employee director compensation policy.

#### Robertsbridge and Brendan May Consulting Agreements
On March 7, 2023, we entered into a consulting agreement with Robertsbridge Consultants Ltd, a consulting firm founded by Mr. May of which he is a director, which is owned by Stonehaven, of which Mr. May is Deputy Chairman, under which Robertsbridge provides environmental consulting services to us. Consulting services during each of the years ended December 31, 2025 and 2024 totaled $5,168 and $122,050, respectively.

In addition, on February 26, 2024, we entered into a consulting agreement with Mr. May for certain consulting services which terminated at the 2024 Annual Meeting.

Consulting fees paid to Mr. May during the year ended December 31, 2024 totaled $26,250.

#### Allseas
On March 29, 2019, we entered into a strategic alliance with Allseas to develop a system to collect, lift and transport nodules from the seafloor to shore and agreed to enter into a nodule collection and shipping agreement whereby Allseas would provide commercial services for the collection of the first 200 million metric tonnes of polymetallic nodules on a cost plus 50% profit basis. In furtherance of this agreement, on July 8, 2019, we entered into a Pilot Mining Test Agreement with Allseas ("PMTA"), which was amended on five occasions through February 2023, to develop and deploy a PMTS, successful completion of which is a prerequisite for our application for an exploitation contract with the ISA. Under the PMTA, Allseas agreed to cover the development cost of the project in exchange for a payment from us upon successful completion of the pilot trial of the PMTS in NORI Area D.

On March 16, 2022, Nauru Ocean Resources Inc. ("NORI") and Allseas entered into a non-binding term sheet for the development and operation of a commercial nodule collection system. The pilot nodule collection system developed and tested by Allseas is expected to be upgraded to a commercial system with a targeted production capacity of 1.3 million tonnes of wet nodules per year with expected production readiness by the fourth quarter of 2024. NORI and Allseas intended to equally finance all costs related to developing and getting the first commercial system into production that were estimated at less than EUR100 million. It was anticipated that NORI would not have to make any payments related to the commercial system to Allseas until March 31, 2023. Once in production, NORI expected to pay Allseas a nodule collection and transshipment fee estimated at approximately EUR 150 per wet tonne in the first year of operations, which was expected to be reduced by more than 20% in the following years as Allseas scaled up production to 1.3 million wet tonnes of nodules per year. Following the successful completion of the NORI Area D pilot collection system trials in November 2022 and subsequent analysis of pilot data, the parties are reviewing Project Zero System production targets (up to 3 Mtpa of wet nodules), system design and cost estimates and intend to enter into a binding Heads of Terms in the second half of 2023.

------

[**TABLE OF CONTENTS**](#TOC)

The parties expect to further detail their relationship in three separate definitive agreements for engineering, conversion/build and commercial operations phase, respectively. Subject to the necessary regulatory approvals, Allseas and NORI also intend to investigate acquiring a second production vessel similar to the Hidden Gem, a further Samsung 10000, with the potential for it to be engineered to support a higher production rate of three million tonnes of wet nodules per year and lower associated per tonne production cost. There can be no assurances, however, that we will enter into definitive agreements with Allseas contemplated by the non-binding term sheet in a particular time period, or at all, or on terms similar to those set forth in the non-binding term sheet, or that if such definitive agreements are entered into by us that the proposed commercial systems and second production vessel will be successfully developed or operated in a particular time period, or at all.

On March 22, 2023, we entered into a Credit Facility with Argentum Credit Virtuti GCV, the parent of Allseas Investments S.A. and an affiliate of Allseas (the "Lender") (the "2023 Credit Facility"), pursuant to which we may borrow from the Lender up to $25,000,000 in the aggregate, from time to time, subject to certain conditions set forth in the 2023 Credit Facility. All amounts drawn under the 2023 Credit Facility will bear interest at the 6-month Secured Overnight Funding Rate (SOFR), 180-day average plus 4.0% per annum payable in cash semi-annually (or plus 5% if paid-in-kind at maturity, at our election) on the first business day of each of June and January. We will pay an underutilization fee equal to 4.0% per annum payable semi-annually for any amounts that remain undrawn under the 2023 Credit Facility. We have the right to pre-pay the entire amount outstanding under the 2023 Credit Facility at any time, before the Credit Facility's maturity. The 2023 Credit Facility also contains customary events of default. On July 31, 2023, the Company entered into the First Amendment to the 2023 Credit Facility to extend same to November 30, 2024. The 2023 Credit Facility was then further amended on March 22, 2024 pursuant to the Second Amendment to the 2023 Credit Facility to further extend the same to August 31, 2025 and to provide that the underutilization fee thereunder shall cease to be payable after the date on which we or the lender gives notice of termination of the agreement. On August 16, 2024, the Company entered into the Third Amendment to the 2023 Credit Facility, to increase the borrowing limit of the 2023 Credit Facility to $27.5 million. On November 14, 2024, as a result of the 2024 registered direct offering the borrowing limit of the 2023 Credit Facility was returned to $25 million. Pursuant to the Letter Agreement entered into on March 24, 2025, discussed below, we agreed to cancel the 2023 Credit Facility with no outstanding amounts remaining, other than our obligation to pay Argentum Credit Virtuti GCV the underutilization fee thereunder.

On May 27, 2024, we entered into a short-term loan agreement with Argentum Credit Virtuti GCV whereby we borrowed $2 million (the "Loan") on May 30, 2024. The Loan matured on September 10, 2024 (maturity date) and accrued interest at a rate of 8% per annum. On the maturity date, we repaid the entire Loan amounting to $2 million and the accrued interest.

On September 9, 2024, we entered into a working capital loan agreement (the "Working Capital Loan Agreement") with Allseas Investments SA (the "Allseas Investments"), a company related to Allseas. In accordance with the Working Capital Loan Agreement, Allseas Investments provided a loan to us amounting to $5 million (the "Working Capital Loan") on September 10, 2024, to be used towards general corporate purposes and the repayment of all outstanding amounts under the short-term loan agreement discussed above. The Working Capital Loan is payable on or before the earlier of (i) the occurrence of certain financing events and (ii) April 1, 2025 (the "Repayment Date"). The Working Capital Loan bears interest based on the 6-month Secured Overnight Financing Rate, 180-day average plus a margin of 4.0% per annum and is payable in two installments on January 2, 2025, and the Repayment Date (or plus a margin of 5.0% if all interest payments are deferred to the Repayment Date, at our election). On October 18, 2024, we entered into the First Amendment to the Working Capital Loan Agreement, resulting in a further draw of $2.5 million by us and a total Working Capital Loan drawn amount of $7.5 million. On March 24, 2025, we entered into a Letter Agreement with Allseas Investments and Argentum Credit Virtuti GCV, pursuant to which the Repayment Date for the Working Capital Loan was extended to September 30, 2025, with principal and interest repayable on that date. In the second quarter of 2025, the entire Working Capital Loan amount along with the interest payable was repaid and the facility was cancelled.

A "Related Person Transaction" is a transaction, arrangement or relationship in which the Company or any of its subsidiaries was, is or will be a participant, the amount of which involved exceeds the lesser of (i) $120,000, and (ii) one percent of the average of the Company's total assets at year end for the last two completed fiscal years, which was $120,000 as of the end of 2025, and in which any related person had, has or will have a direct or indirect material interest. Transactions involving compensation for services provided to the Company or any of its subsidiaries as an employee, consultant or director will not be considered related person transactions under this policy. A "Related Person" is:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • any person who is or was an executive officer, director, or director nominee of the Company at any time since the beginning of the Company's last fiscal year;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • a person who is or was an Immediate Family Member (as defined below) of an executive officer, director, director nominee at any time since the beginning of the Company's last fiscal year;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • any person who, at the time of the occurrence or existence of the transaction, is the beneficial owner of more than 5% of any class of the Company's voting securities (a "Significant Shareholder"); or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • any person who, at the time of the occurrence or existence of the transaction, is an Immediate Family Member of a Significant Shareholder of the Company.

An "Immediate Family Member" of a person is any child, stepchild, parent, stepparent, spouse, sibling, mother-in-law, father-in-law, son-in-law, daughter-in-law, brother-in-law or sister-in-law of such person, or any other person sharing the household of such person, other than a tenant or employee.

The Company has implemented policies and procedures designed to minimize potential conflicts of interest arising from any dealings it may have with its affiliates and to provide appropriate procedures for the disclosure of any real or potential conflicts of interest that may exist from time to time to supplement the voting restrictions with respect to certain conflicted transactions under the laws of British Columbia. Specifically, pursuant to its charter, the audit committee has the responsibility to review related party transactions.

Under the related person transaction policy, the related person in question or, in the case of transactions with a beneficial holder of more than 5% of the Company's voting stock, an officer with knowledge of a proposed transaction, will be required to present information regarding the proposed related person transaction to the audit committee (or to another independent body of the board of directors) for review.

To identify Related Person Transactions in advance, we expect to rely on information supplied by our executive officers, directors and certain significant shareholders. In considering related person

------

[**TABLE OF CONTENTS**](#TOC)

transactions, our audit committee is expected to take into account the relevant available facts and circumstances, which may include, but are not limited to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the related person's interest in the transaction;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the approximate dollar value of the amount involved in the transaction;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the approximate dollar value of the amount of the related person's interest in the transaction without regard to the amount of any profit or loss;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • whether the transaction was undertaken in the ordinary course of business of the Company;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • whether the transaction with the related person is proposed to be, or was, entered into on terms no less favorable to the Company than terms that could have been reached with an unrelated third-party;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the purpose of, and the potential benefits to the Company of, the transaction; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • any other information regarding the transaction or the related person in the context of the proposed transaction that would be material to investors in light of the circumstances of the particular transaction.

The audit committee will approve only those transactions that it determines are fair to the Company and in the Company's best interests.

#### PROPOSAL NOS. 1 AND 2 ELECTION OF DIRECTORS (Notice Items 1 and 2)

#### Number of Directors (Proposal No. 1)
Our Articles provide that our shareholders fix the number of directors to be elected to our board of directors by ordinary resolution. The shareholders may increase or decrease the number of directors constituting the full board of directors, provided that such number may not be less than three. Our board of directors currently consists of ten members. The remaining ten directors are up for re-election at the Annual Meeting. Therefore, we are proposing that shareholders fix the number of directors to be elected at the Annual Meeting at ten.

The affirmative vote of a majority of the shares cast for this proposal is required to set the number of directors at ten.

 **OUR BOARD OF DIRECTORS RECOMMENDS THAT THE NUMBER OF DIRECTORS BE SET AT TEN, AND PROXIES SOLICITED BY OUR BOARD OF DIRECTORS WILL BE VOTED IN FAVOR THEREOF UNLESS A SHAREHOLDER HAS INDICATED OTHERWISE ON THE PROXY.** 

#### Election of Directors (Proposal No. 2)
Our board of directors nominated Gerard Barron, Andrew Greig, Andrew Hall, Sheila Khama, Andrei Karkar, Christian Madsbjerg, Brendan May, Stephen Jurvetson, Michael Hess and Alex Spiro for election at the Annual Meeting. If they are elected, they will serve on our board of directors until the 2027 annual meeting of shareholders or until their respective successors have been elected or appointed, unless their offices are earlier vacated.

Unless authority to vote for any of these nominees is withheld, the shares represented by the enclosed proxy will be voted **FOR** the election of Gerard Barron, Andrew Greig, Andrew Hall, Michael Hess, Stephen Jurvetson, Andrei Karkar, Sheila Khama, Christian Madsbjerg, Brendan May and Alex Spiro as directors. In the event that any nominee becomes unable or unwilling to serve, the shares represented by the enclosed proxy will be voted for the election of such other person as our board of directors may recommend in that nominee's place. We have no reason to believe that any nominee will be unable or unwilling to serve as a director.

A plurality of the shares voted for each nominee at the Annual Meeting is required to elect each nominee as a director.

 **OUR BOARD OF DIRECTORS RECOMMENDS THE ELECTION OF GERARD BARRON, ANDREW GREIG, ANDREW HALL, MICHAEL HESS, STEPHEN JURVETSON, ANDREI KARKAR, SHEILA KHAMA, CHRISTIAN MADSBJERG, BRENDAN MAY AND ALEX SPIRO AS DIRECTORS, AND PROXIES SOLICITED BY OUR BOARD OF DIRECTORS WILL BE VOTED IN FAVOR THEREOF UNLESS A SHAREHOLDER HAS INDICATED OTHERWISE ON THE PROXY.**

#### PROPOSAL NO. 3 APPOINTMENT OF THE INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM (Notice Item 3)
The audit committee recommends appointment of Ernst & Young LLP ("EY"), as our independent registered public accounting firm, to audit our financial statements for the fiscal year ending December 31, 2026. EY has served as our independent registered public accounting firm since 2012, including the period before the closing of the Business Combination in which EY was engaged by DeepGreen. Our board of directors proposes that the shareholders approve this appointment. EY audited our financial statements for the fiscal year ended December 31, 2025. We expect that representatives of EY will be present at the Annual Meeting, will be able to make a statement if they so desire, and will be available to respond to appropriate questions.

In deciding to appoint EY, the audit committee reviewed auditor independence issues and existing commercial relationships with EY and concluded that EY has no commercial relationship with the Company that would impair its independence for the fiscal year ending December 31, 2026.

The following table presents fees for professional audit services rendered by EY for the audit of the Company's annual financial statements for the years ended December 31, 2025 and 2024, and fees billed for other services rendered by EY during those periods.

---

| | | |
|:---|:---|:---|
| | **2025**  | **2024**  |
| **Audit fees:<sup>(1)</sup>**  | $1151867.21 | $770587 |
| **Audit-related fees: .**  | $27277.07 | $40113 |
| **Tax fees:**  |  |  |
| **All other fees:**  |  |  |

---

(1) Consist of aggregate fees for professional services provided in connection with the annual audits of our consolidated financial statements, the review of our quarterly condensed consolidated financial statements, and fees related to accounting matters that were addressed during the annual audit and quarterly reviews. This category also includes fees for services that were incurred in connection with regulatory filings or engagements.

#### Description of Fees:
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 1. ***Audit fees*** include audit work performed in the preparation of financial statements, as well as work that generally only an independent registered public accounting firm can reasonably be expected to provide, including comfort letters, statutory audits, and attest services and consultation regarding financial accounting and/or reporting standards.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 2. ***Audit-related fees*** are for assurance and related services that are traditionally performed by an independent registered public accounting firm, including due diligence related to mergers and acquisitions, employee benefit plan audits, and special procedures required to meet certain regulatory requirements.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 3. ***Tax fees*** include all services performed by an independent registered public accounting firm's tax personnel except those services specifically related to the audit of the financial statements, and includes fees in the areas of tax compliance, tax planning, and tax advice.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 4. ***All other fees*** are those associated with services not captured in the other categories. The Company generally does not request such services from our independent registered public accounting firm.

#### Pre-Approval Policy and Procedures
The audit committee's charter sets forth the audit committee's obligations relating to the approval of all audit and non-audit services that are to be performed by our independent registered public accounting firm. The charter provides that we will not engage our independent registered public accounting firm to provide audit or non-audit services unless the service is pre-approved by the audit committee. In addition,

------

[**TABLE OF CONTENTS**](#TOC)

we will not engage any other accounting firm to provide audit services unless such services are pre-approved by the audit committee.

In connection with the foregoing, the audit committee may approve specific services in advance. In addition, from time to time, the audit committee may pre-approve specified types of services that are expected to be provided to us by our independent registered public accounting firm in the future. Any such pre-approval of types of services is detailed as to the particular service or type of service to be provided and is also generally subject to a maximum dollar amount.

The audit committee has also delegated to the chairperson of the audit committee the authority to approve any audit or non-audit services to be provided to us by our independent registered public accounting firm. Any approval of services by the chairperson of the audit committee pursuant to this delegated authority is reported on at the next meeting of the audit committee.

A plurality of the shares cast for this proposal is required to appoint the independent registered public accounting firm. In the event the shareholders do not appoint EY as our independent registered public accounting firm, the audit committee will reconsider its appointment.

 **OUR BOARD OF DIRECTORS RECOMMENDS A VOTE TO APPOINT ERNST & YOUNG LLP AS OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM, AND PROXIES SOLICITED BY OUR BOARD OF DIRECTORS WILL BE VOTED IN FAVOR OF SUCH APPOINTMENT UNLESS A SHAREHOLDER INDICATES OTHERWISE ON THE PROXY.**

#### PROPOSAL NO. 4 — NON-BINDING ADVISORY VOTE ON APPROVAL OF EXECUTIVE COMPENSATION AS DISCLOSED IN THIS PROXY STATEMENT
We are seeking your advisory vote as required by Section 14A of the Securities Exchange Act of 1934, as amended, on the approval of the compensation of our named executive officers, which are sometimes referred to as "NEOs", as described in the section entitled "*Executive Officer and Director Compensation*" and related material contained in this proxy statement. Because your vote is advisory, it will not be binding on our compensation committee or our board of directors. However, the compensation committee and the board of directors will review the voting results and take them into consideration when making future decisions regarding executive compensation.

Our executive compensation program was designed to provide our NEOs with meaningful incentives and rewards, while effectively balancing the short-term and long-term interests of our shareholders with our ability to attract and retain talented executives. We have created a compensation program that combines short-term and long-term components, cash, equity, fixed and performance- based contingent payments, in the proportions that we believe achieve four guiding principles:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • enhance shareholder value by aligning the financial interests of our NEOs with those of our shareholders;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • enable us to attract, motivate and retain the people needed to define and lead our industry;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • integrate compensation closely with the achievement of our business and performance objectives; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • reward the individual performance that contributes to our short-term and long-term success.

Shareholders are urged to read the "*Executive Officer and Director Compensation*" section of this proxy statement, which discusses how our compensation policies and procedures implement our compensation philosophy. The compensation committee and the board of directors believe that these policies and procedures are effective in implementing our compensation philosophy and in achieving our goals.

During fiscal year 2025, we continued to make progress on our strategic plan. Some of our most notable business achievements during fiscal year 2025 include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • In February 2025, we announced that Pacific Metals Co. Ltd. ("PAMCO") had successfully smelted 450 tonnes of calcine into 35 tonnes of NiCuCo alloy and 320 tonnes of Mn silicate products, during a campaign to process a 2,000-tonne sample of deep-seafloor polymetallic nodules at our partner PAMCO's Hachinohe Rotary Kiln Electric-Arc Furnace facility in Hachinohe, Japan, demonstrating the process at scale. The process data and operational experience gathered during the processing trial was used by PAMCO to complete a feasibility study in June 2025 which will inform expected definitive processing agreements between the parties.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • In April 2025, The Metals Company USA, LLC ("TMC USA"), our wholly owned subsidiary, submitted to National Oceanographic and Atmospheric Administration ("NOAA") under the Deep Seabed Hard Mineral Resources Act of 1980 ("DSHMRA") two exploration license applications covering 187,017 square kilometers in the Clarion Clipperton Zone ("CCZ") and one commercial recovery permit application covering 25,160 square kilometers in the CCZ. In January 2026, TMC USA submitted a consolidated exploration license and commercial recovery permit application covering 65,187 square kilometers in the CCZ under NOAA's new consolidated application and review process.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • The August 2025 release of the results of a pre-feasibility study on one of our development areas in a report titled S-K 1300 Prefeasibility Study for NORI Area D: Technical Report Summary, dated August 4, 2025, prepared by AMC Consultants Pty Lt. and other qualified persons, which declared the world's first mineral reserves for a seafloor polymetallic nodule project demonstrating the project's economic viability.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • The August 2025 release of an initial assessment of our other development areas in a report titled S-K 1300 Technical Report Summary — Initial Assessment of TOML and NORI

Properties, Clarion-Clipperton Zone, dated August 4, 2025, prepared by AMC Consultants Pty Lt. and other qualified persons.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • On August 11, 2025, TMC USA received notice of full compliance from NOAA on its exploration applications, and confirmation that TMC USA has priority right over both exploration areas. Both applications entered the certification stage in late July 2025. The news followed earlier determinations by NOAA in May 2025 that the applications were in substantial compliance, which we believe demonstrates a systematic regulatory process under DSHMRA as we target a fourth quarter 2027 commissioning, subject to timely obtaining all necessary regulatory approvals.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • In November 2025, we announced that we had successfully produced battery-grade manganese sulfate from our nodule-derived manganese silicate product during bench scale trials at our partner KPM's operating facility in Ontario. North America is largely reliant on foreign sources of manganese. As the planet's largest source of manganese, nodules hold significant potential to supply a range of key industries from steelmaking and infrastructure to energy, defense and automotive manufacturing, with automakers increasingly turning toward manganese-rich cathode chemistries for their next-generation electric vehicles.

In accordance with the rules of the SEC, the following resolution, commonly known as a "say-on-pay" vote, is being submitted for a shareholder vote at Annual Meeting:

"RESOLVED, on an advisory basis, that the compensation paid to the named executive officers of TMC the metals company Inc., as disclosed pursuant to the compensation disclosure rules of the Securities and Exchange Commission, including under the section of this proxy statement "*Executive Officer and Director Compensation*" and the related material disclosed in this proxy statement, is hereby APPROVED."

The affirmative vote of a majority of the shares cast for this proposal is required to approve, on a non-binding advisory basis, this resolution.

 **OUR BOARD OF DIRECTORS RECOMMENDS A VOTE TO APPROVE, ON A NON-BINDING ADVISORY BASIS, THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS, AND PROXIES SOLICITED BY THE BOARD OF DIRECTORS WILL BE VOTED IN FAVOR OF SUCH APPROVAL UNLESS A SHAREHOLDER INDICATES OTHERWISE ON THE PROXY** 

------

[**TABLE OF CONTENTS**](#TOC)

#### PROPOSAL NO. 5 — NON-BINDING ADVISORY VOTE ON APPROVAL OF THE FREQUENCY OF HOLDING A NON-BINDING ADVISORY VOTE ON THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS
We are seeking your input regarding the frequency of future shareholder advisory votes on the compensation of our named executive officers for the next six years. In particular, we are asking whether the advisory vote on the compensation of our named executive officers should occur every year, every two years or every three years. We are recommending that the advisory vote on the compensation of our named executive officers be held every <u>two years</u>. Because your vote is advisory, it will not be binding on our compensation committee or our board of directors. However, the compensation committee and the board of directors will review the voting results and take them into consideration in determining how frequently to present the advisory vote on the compensation of our named executive officers to our shareholders in the future.

We recommend that shareholders approve an advisory vote on named executive officer compensation be held every <u>two years</u>, or biennially, because our compensation program is designed to drive and reward performance over multiple years, and we believe a two-year cycle provides a more meaningful period for shareholders to evaluate the results of our compensation programs against our longer-term strategy and achievements. We believe a biennial vote also strikes an appropriate balance between regular shareholder input and the stability and continuity needed to administer and refine our compensation program, while giving the compensation committee and the board of directors sufficient time to consider feedback, engage with shareholders as needed, and implement any appropriate changes. We believe this approach supports our objective of creating a compensation program that promotes the four guiding principles discussed elsewhere in this proxy statement.

The proxy card provides shareholders with the opportunity to choose among four options (holding the vote every one, two or three years, or abstaining) and, therefore, shareholders will not be voting to approve or disapprove the board of directors' recommendation of two years. The frequency of holding an advisory vote on the compensation of our named executive officers — every year, every two years or every three years — receiving the majority of votes cast will be the frequency approved, on an advisory basis, by our shareholders. However, because the vote on the frequency of holding future advisory votes on the compensation of our named executive officers is not binding, if none of the frequency options receives a majority vote, we will consider the option receiving the greatest number of votes as the frequency preferred by our shareholders.

 **OUR BOARD OF DIRECTORS RECOMMENDS A VOTE TO APPROVE, ON A NON-BINDING ADVISORY BASIS, HOLDING AN ADVISORY VOTE ON THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS EVERY <u>TWO YEARS</u>, AND PROXIES SOLICITED BY THE BOARD OF DIRECTORS WILL BE VOTED IN FAVOR OF SUCH FREQUENCY UNLESS A SHAREHOLDER INDICATES OTHERWISE ON THE PROXY CARD.**

#### CODE OF BUSINESS CONDUCT AND ETHICS
We have adopted a code of business conduct and ethics that applies to all of our directors, officers and employees, including our principal executive officer, principal financial officer and principal accounting officer, which is available on our website at *www.metals.co* under Investors — Governance — Corporate Governance Overview — Governance Documents. Our code of business conduct is a "code of ethics," as defined in Item 406(b) of Regulation S-K.

We will make any legally required disclosures regarding amendments to, or waivers of, provisions of our code of ethics in a Current Report on Form 8-K within four business days following the date of the amendment or waiver, unless website posting or the issuance of a press release of such amendment or waiver is then permitted by Nasdaq rules.

#### DELINQUENT SECTION 16(a) REPORTS
Pursuant to Section 16 of the Securities Exchange Act of 1934, as amended, executive officers, directors, and holders of more than 10% of our common shares are required to file reports of their transactions our equity securities with the SEC. Based solely on a review of the copies of such reports received by us, or written representations from certain reporting persons, we believe that all filings required to be made by its reporting persons complied with all applicable Section 16 filing requirements during the year ended December 31, 2025, with the exception of Form 3 filed on behalf of director Michael Hess on July 22, 2025 reporting his initial holdings, a Form 4 filed on behalf of Allseas Group S.A., Edward Heerema, Allseas Investments S.A., Argentum Cedit Virtuti NV, and Stichting Administratiekantoor Aequa Lance Foundation, on May 27, 2025 reporting transactions that occurred on May 22, 2025, and a Form 4 filed on behalf of director Anthony O'Sullivan on August 28, 2025 reporting transactions that occurred on May 27, 2025, June 9, 2025 and June 20, 2025.

#### OTHER MATTERS
Our board of directors knows of no other business which will be presented to the Annual Meeting. If any other business is properly brought before the Annual Meeting, proxies will be voted in accordance with the judgment of the persons named therein.

#### SHAREHOLDER PROPOSALS AND NOMINATIONS FOR DIRECTOR
To be considered for inclusion in the management information circular (or proxy statement) for the annual general meeting of shareholders to be held during 2027 pursuant to Rule 14a-8 under the Securities Exchange Act of 1934, as amended, we must receive shareholder proposals (other than for director nominations) no later than December 18, 2026. In addition, pursuant to Part 5, Division 7 of the *Business Corporations Act* (British Columbia), any notice of a shareholder's proposal intended to be raised at the annual general meeting of our shareholders to be held during 2027, must be submitted to us at our registered office, on or before February 28, 2027 to be considered for inclusion in the proxy statement (or management information circular) for such meeting. Under and as further set out in our Articles, director nominations for election at the annual general meeting of our shareholders to be held during 2027, although not included in the management information circular (or proxy statement), must meet all the requirements set out in the Articles, including being received not less than 30 days prior to the date of the annual general meeting of our shareholders to be held during 2027; provided, that if the first public announcement of the date of the annual general meeting of our shareholders to be held during 2027 (the "Notice Date") is less than 50 days before the date of such meeting, director nominations must be made not later than the close of business on the 10th day following the Notice Date. In addition to satisfying the foregoing advance notice requirements, to comply with the SEC's universal proxy rules, shareholders who intend to solicit proxies in support of director nominees other than our nominees at the annual general meeting of our shareholders to be held during 2027 must follow the requirements set forth in Rule 14a-19 as promulgated under the Exchange Act, including the requirement that any notice under Rule 14a-19 must be postmarked or transmitted electronically to us at our principal executive office no later than March 29, 2027. Proposals that are not received in a timely manner will not be voted on at the annual general meeting of our shareholders to be held during 2027. If a proposal is received on time, the proxies that management solicits for the annual general meeting of our shareholders to be held during
