Letter to Shareholders

April 18, 2025

To Our Shareholders:

You are cordially invited to attend the 2025 annual and special meeting of shareholders of TMC the metals company Inc. (the “Company”) to be held in a virtual format on Thursday, May 29, 2025 at 10:00 a.m. EDT.

This year’s annual and special meeting will be held virtually via live audio webcast on the internet. We believe hosting a virtual annual and special 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 and special meeting. You will be able to attend the annual and special meeting, vote and submit your questions during the annual and special meeting by visiting https://www.cstproxy.com/metals/2025. You will not be able to attend the annual and special 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 and special meeting, we will present the audited consolidated financial statements for the fiscal year ended December 31, 2024 and the auditors’ report thereon, we will ask the shareholders to set the number of directors at eight and elect eight 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 our fiscal year ending December 31, 2025 and to adopt an amendment to our articles to update the advance notice provisions with respect to the address of our registered and records office. Our board of directors recommends the approval of each of the proposals and the election of each director nominee. Such other business will be transacted as may properly come before the annual and special meeting.

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 18, 2025, 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 our 2025 annual and special meeting of shareholders 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 and special meeting and how to receive a paper copy of the proxy materials by mail.

We hope you will be able to attend the annual and special meeting. Whether or not you plan to attend the annual and special 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 and special meeting.

Sincerely,

Gerard Barron
Chairman & Chief Executive Officer

TABLE OF CONTENTS

IMPORTANT INFORMATION ABOUT THE ANNUAL AND SPECIAL MEETING AND VOTING

Why is the Company soliciting my proxy?

Our board of directors is soliciting your proxy to vote at the 2025 annual and special meeting of shareholders of TMC the metals company Inc. (the “Annual Meeting”) to be held virtually on Thursday, May 29, 2025, at 10:00 a.m. EDT and any adjournments or postponements of the meeting. This proxy statement, along with the accompanying Notice of Annual and Special 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 and Special Meeting of Shareholders, the proxy card and a copy of our Annual Report on Form 10-K for the year ended December 31, 2024 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 Internet Availability Notice (the “Notice”), and, if applicable, proxy materials to shareholders on or about April 18, 2025.

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/2025 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/

TABLE OF CONTENTS

2025, typing your question into the “Ask a Question” field, and clicking “Submit.” Please submit any questions before the start time of the meeting.

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 3, 2025 (the “Record Date”) will be entitled to vote at the Annual Meeting. On this Record Date, there were 358,705,212 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

TABLE OF CONTENTS

Proposal Nos. 1 and 4. If you properly submit a proxy without giving specific voting 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:

•

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

•

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.

•

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 28, 2025.

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 in virtually at the Annual Meeting, you should contact your broker or agent to obtain a legal proxy or broker’s proxy card and bring it to 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:

•

“FOR” the approval of setting the number of directors at eight;

•

“FOR” the election of the nominees for director;

•

“FOR” the appointment of Ernst & Young LLP as our independent registered public accounting firm for our fiscal year ending December 31, 2025; and

•

“FOR” the adoption of an amendment to the Company’s Articles (“Articles”) to update the advance notice provisions with respect to the address of the Company’s registered and records office (the “Amendment”).

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:

•

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;

•

by re-voting by Internet as instructed above;

•

by notifying the Company’s Secretary in writing before the Annual Meeting that you have revoked your proxy; or

TABLE OF CONTENTS

•

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 the Articles, a copy of which is available at 1111 West Hastings Street, 15th 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, 15th 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 eight (Proposal No. 1 of this proxy statement), on the appointment of our independent registered public accounting firm (Proposal No. 3 of this proxy statement) and on the approval of the Amendment to our Articles (Proposal No. 4 of this proxy statement) without receiving instructions from you. 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. 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 or because your broker chooses not to vote on a matter for which it does have discretionary voting authority.

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

	Proposal No. 1: Set Number of Directors at Eight			The affirmative vote of a majority of the shares cast for this proposal is required to set the number of directors at eight. 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 have authority to vote customers’ unvoted shares held by the firms in street name on this proposal. If a broker does not exercise this authority, such broker non-votes will have no effect on the results of this vote.
	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

TABLE OF CONTENTS

				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. Brokerage firms have authority to vote customers’ unvoted shares held by the firms in street name on this proposal. If a broker does not exercise this authority, such broker non-votes will have no effect on the results of this vote.
	Proposal No. 4: Amendment to Articles of the Company			The affirmative vote of a majority of the shares cast for this proposal is required to amend the Articles of the Company as more particularly set out below. 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 have authority to vote customers’ unvoted shares held by the firms in street name on this proposal. If a broker does not exercise this authority, such broker non-votes will have no effect on the results of this vote.

Where can I find the voting results of the Annual Meeting?

The preliminary voting results will be announced at the Annual Meeting, and we will publish preliminary, or final results if available, in a Current Report on Form 8-K within four business days of the Annual Meeting. If final results are unavailable at the time we file the Form 8-K, then we will file an amended report on Form 8-K to disclose the final voting results within four business days after the final voting results are known.

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?

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 meeting is necessary to constitute a quorum at the Annual Meeting. 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.

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/2025. The Annual Meeting will be held at 10:00 a.m. EDT on Thursday, May 29, 2025. To attend the virtual Annual Meeting, go to https://www.cstproxy.com/metals/2025 shortly before the meeting time, enter your name, email address and control number to enter the meeting portal. If you miss the Annual Meeting, you can view a replay of the Webcast at https://www.cstproxy.com/metals/2025 until June 29, 2025. You need not attend the Annual Meeting in order to vote.

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

TABLE OF CONTENTS

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, 15th 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:

•

following the instructions provided on your Notice or proxy card;

•

following the instructions provided when you vote over the Internet; or

•

going to https://www.cstproxy.com/metals/2025 and following the instructions provided.

TABLE OF CONTENTS

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

The following table sets forth information known to the Company regarding the beneficial ownership of the Common shares as of April 3, 2025 by:

•

each person known to the Company to be the beneficial owner of more than 5% of outstanding common shares;

•

each of the Company’s named executive officers and directors and each director nominee that is not a current director; and

•

all of the Company’s executive officers and current directors as a group.

Beneficial ownership is determined according to the rules of the SEC, which generally provide that a person has beneficial ownership of a security if he, she or it possesses sole or shared voting or investment power over that security, including options and warrants that are currently exercisable or exercisable within 60 days. Common shares issuable upon exercise of options and warrants currently exercisable within 60 days are deemed outstanding solely for purposes of calculating the percentage of total ownership and total voting power of the beneficial owner thereof.

The beneficial ownership of common shares is based on 358,705,212 common shares issued and outstanding as of April 3, 2025.

Unless otherwise indicated, the Company believes that each person named in the table below has sole voting and investment power with respect to all common shares beneficially owned by them. Unless otherwise indicated, the business address of each of the following entities or individuals is c/o TMC the metals company Inc., 1111 West Hastings Street, 15th Floor, Vancouver, British Columbia V6E 2J3.

In the year ended December 31, 2024, FW Cook only did work for the compensation committee.

Sustainability and Innovation Committee

Our sustainability and innovation committee met four times during the year ended December 31, 2024. Our sustainability and innovation committee currently consists of Brendan May, who serves as the chairperson, Christian Madsbjerg and Amelia Kinahoi Siamomua. Ms. Kinahoi Siamomua is not up for re-election as director at the Annual Meeting. We expect Sheila Khama will join the sustainability and innovation committee upon election of directors at the Annual Meeting.

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 have 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 possess 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) as well as five (5) other independent director nominees, which seek to ensure the powers and duties of the dual role are handled responsibly. Furthermore, consistent with Nasdaq listing requirements, the independent directors regularly have the opportunity to meet in executive sessions without Messrs. Barron and Jurvetson 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 have 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 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 [email protected]. 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, 15th 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:

•

junk mail and mass mailings;

•

resumes and other forms of job inquiries;

•

surveys; and

•

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, contracts, directors and officers to engage in short-term or speculative transactions involving our securities, which includes:

•

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);

•

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;

•

borrowing or other arrangements involving pledge of securities; and

•

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

TABLE OF CONTENTS

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, 2024 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, 2024, 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.

As previously disclosed, in March 2024, we identified errors in the financial statements and related disclosures in our Quarterly Reports on Form 10-Q for the quarter ended March 31, 2023, for the six months ended June 30, 2023 and nine months ended September 30, 2023 and revised these financial statements in our Annual Report on Form 10-K for the year ended December 31, 2023, after which, management concluded that no adjustments to executive compensation were required because no compensation was paid to the executive officers under performance-based compensation awards pursuant to any performance goals impacted by the revisions and, therefore, that there was no excess incentive-based compensation to recover.

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 currently considered 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, 2024. As of December 31, 2024, our NEOs were:

•

Gerard Barron, Chief Executive Officer;

•

Craig Shesky, Chief Financial Officer; and

•

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.

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. Our executive compensation plan includes base salaries, Short-Term Incentive Program (paid in restricted share units for 2024), and a Long-Term Incentive Program (granted in the form of restricted share units grants for 2024).

As discussed in more detail below, in 2024, 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 has the primary responsibility for establishing our executive compensation philosophy and determining the specific components and levels of each named executive officer’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:

•

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

•

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

•

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

•

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 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

TABLE OF CONTENTS

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.

Elements of Compensation for Our NEOs

Our executive compensation program consists of three principal components: base salary, STIP, and the 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 2024 Compensation Plans for Our NEOs

Compensation Element	Primary Purpose	Performance Period	Details
Cash Compensation
Base Salary	Reward for ongoing work performed, executive tenure and role	Ongoing	Provided in cash each pay period.
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. Awards are paid in cash upon the completion of the fiscal year; however, for 2024, 2023 and 2022, at the election of the Company, STIP awards were paid in immediately-vested RSUs to conserve operating cash.
Equity Compensation
Long-term incentives (LTIP)	Reinforce and drive long-term shareholder value Retain executives over a multi-year period Incentivize the achievement by management of multi-year performance goals	3 years	For 2024, 2023 and 2022, grants were in the form of RSUs that vest one-third per year over three years.

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.

TABLE OF CONTENTS

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

•

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

•

the executive’s level of responsibility and duties;

•

a comparison to grant levels of other executive officers;

•

individual named executive officers’ performance;

•

our corporate performance;

•

our total equity compensation costs relative to total expenses;

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 to our NEOs under the STIP and LTIP for the 2024 performance year, including to our Chief Executive Officer. They considered, to the extent applicable, our corporate performance and individual contributions in 2024 as well as in prior years. The compensation committee determined the value of each LTIP equity award as time-based RSUs that vest one-third per year over three years based on the potential equity compensation expense and the target award size, as well as the retention and incentive aspects of the award. The total value was also informed by the competitive analysis conducted by FW Cook, the independent compensation consulting firm engaged by our compensation committee to provide competitive market data as well as advice on pay levels and compensation program structure. See “Summary Compensation Table” and “Outstanding Equity Awards at 2024 Fiscal Year-End”.

Compensation of Our Chief Executive Officer and Chairman in 2024

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.

Cash Compensation

Annual Salary

The Signing RSUs will 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 vest on achievement of a Closing Price of $7.50; one-third of the Signing RSUs vest on achievement of a Closing Price of $10.00; and one-third of the Signing RSUs vest on 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 are not vested 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.

The treatment of the Signing RSUs upon a change of control is intended to align Mr. Barron’s interests with the interests of the Company’s other shareholders with respect to evaluating potential change of control offers.

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.

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 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 fulfilment of any conditions or

TABLE OF CONTENTS

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 Board 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 70,262,856 common shares, which number includes 13,628,338 shares added to the plan in January 2025 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 3, 2025, there were 28,998,905 common shares underlying restricted stock units outstanding and 4,440,000 common shares underlying options, and 43,565,373 common shares remained available for future issuance 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 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

TABLE OF CONTENTS

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

TABLE OF CONTENTS

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:

•

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

•

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;

•

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;

•

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

•

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 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

TABLE OF CONTENTS

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

•

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 for 2024 were made on February 26, 2025 at a regularly scheduled meeting of the compensation committee, and the compensation committee anticipates continuing to grant LTIP awards generally in February of each year going forward. The compensation committee and the board of directors does 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 2024.

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		$	30,000
Audit committee chairperson		$	22,500
Audit committee member		$	7,500
Compensation committee chairperson		$	15,000
Compensation committee member		$	5,000
Nominating and corporate governance committee chairperson		$	15,000
Nominating and corporate governance committee member		$	5,000
Sustainability and innovation committee chairperson		$	15,000
Sustainability and innovation committee member		$	5,000

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, the majority of our directors agreed to a temporary change in the method of payment of their annual cash retainers and elected to receive RSUs in lieu of their cash retainers. The number of RSUs will be calculated by dividing the deferred cash compensation by the

TABLE OF CONTENTS

closing share price on the date of the upcoming Annual Meeting. These RSUs will vest immediately and will 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 his 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.

The table below summarizes the compensation of each person serving as a non-employee director of TMC for the fiscal year ended December 31, 2024. Gerard Barron, our Chief Executive Officer, did not receive any additional compensation for his service as a director of TMC in 2024. 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.

CERTAIN RELATIONSHIPS AND RELATED PERSON TRANSACTIONS

In addition to the director and executive officer compensation arrangements discussed above in “Executive Officer and Director Compensation,” since January 1, 2023, 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. 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. Gerard Barron, Craig Shesky, and other members of the Company’s board of directors also agreed to purchase securities in the Registered Offering.

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.

TABLE OF CONTENTS

each of the years ended December 31, 2024 and 2023 totaled $200,000 and $331,000, respectively. Mr. Stone is no longer an executive officer.

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 of $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, 2024 and December 31, 2023 totaled $122,050 and $304,065, 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. Under this consulting agreement, we paid consulting fees to Mr. May of $8,750 per month and granted Mr. May RSUs for 17,241 common shares that vested on March 1, 2025.

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. 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

TABLE OF CONTENTS

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 now repayable on that date.

On August 1, 2023, the Company entered into an Exclusive Vessel Use Agreement with Allseas pursuant to which Allseas will give exclusive use of the vessel (“Hidden Gem”) to the Company in support of the development of the Project Zero Offshore System until the system is completed or December 31, 2026, whichever is earlier. In consideration of the exclusivity term, the Company, on August 14, 2023, issued 4.15 million common shares to Allseas.

TABLE OF CONTENTS

Through December 31, 2024, we have made the following payments to Allseas under the PMTA: (a) $10 million in cash in February 2020, (b) $10 million through the issuance of 3.2 million common shares valued at $3.11 per share in February 2020, (c) issued Allseas a warrant to purchase 11.6 million common shares at a nominal exercise price per share in March 2021, which became exercisable in November 2022 with the successful completion of the pilot trial of the PMTS in the NORI Area D, (d) $10 million in cash in October 2021, following the closing of the Business Combination and meeting certain progress targets on the PMTS, (e) the second $10 million payment to Allseas under the PMTA on April 25, 2022, following the successful completion of the North Sea drive test and (f) the third and final $10 million payment to Allseas became due in November 2022 upon successful completion of the pilot trial of the PMTS in the NORI Area D, which we settled, along with certain other costs due to Allseas under the PMTA. On August 9, 2023, 11,578,620 common shares were issued to Allseas upon the exercise of the warrant that was granted to Allseas in March 2021, and receipt of the exercise fee of $115.8 thousand. The warrant vested and became exercisable on successful completion of the PMTS in November 2022. In the last quarter of 2024, we paid EUR 0.4 million to an affiliate of Allseas for Nodule offloading and shipping charges. As at December 31, 2024, the total amount payable to Allseas and its affiliates was $33.3 million.

Amended and Restated Registration Rights Agreement

At the closing of the Business Combination, we, the initial shareholders, including the Sponsor (the “Sponsor Group Holders”), and certain holders of DeepGreen securities immediately prior to the Effective Time (the “DeepGreen Holders”) entered into an amended and restated registration rights agreement (the “Amended and Restated Registration Rights Agreement”), pursuant to which, among other things, the Sponsor Group Holders and the DeepGreen Holders were granted certain registration rights with respect to their respective common shares on the terms and subject to the conditions therein.

Indemnity Agreements with Officers and Directors and Directors’ and Officers’ Liability Insurance

The Company enters into indemnity agreements with each of its directors and executive officers. Each indemnity agreement provides for indemnification and advancements by the Company of certain expenses and costs relating to claims, suits or proceedings arising from his or her service to the Company, or, at the Company’s request, service to other entities, as officers or directors to the maximum extent permitted by applicable law. The Company also maintains a general liability insurance policy, which covers certain liabilities of its directors and officers arising out of claims based on acts or omissions in their capacities as directors or officers.

Policies and Procedures for Related Party Transactions

We have adopted a written related person transaction policy that sets forth the following policies and procedures for the review and approval or ratification of related person transactions.

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 2024, 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:

•

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;

•

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;

•

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

TABLE OF CONTENTS

•

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

•

the related person’s interest in the transaction;

•

the approximate dollar value of the amount involved in the transaction;

•

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;

•

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

•

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;

•

the purpose of, and the potential benefits to the Company of, the transaction; and

•

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. Our shareholders set the number of directors at eight at the 2023 annual meeting of shareholders held on May 30, 2023, and the directors appointed an additional director pursuant to the Articles and the Business Corporations Act (British Columbia) in April 2024, increasing the number of directors to nine. As a result, our board of directors currently consists of nine members. 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. We are proposing that shareholders fix the number of directors to be elected at the Annual Meeting at eight.

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

OUR BOARD OF DIRECTORS RECOMMENDS THAT THE NUMBER OF DIRECTORS BE SET AT EIGHT, 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 Hall, Andrew Greig, Sheila Khama, Andrei Karkar, Christian Madsbjerg, Brendan May, and Stephen Jurvetson for election at the Annual Meeting. If they are elected, they will serve on our board of directors until the 2026 annual meeting of shareholders or until their respective successors have been elected or appointed, unless their offices are earlier vacated. Amelia Kinahoi Siamomua is not up for re-election as director at the Annual Meeting and her term as director will end at the Annual Meeting.

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 Hall, Andrew Greig, Sheila Khama, Andrei Karkar, Christian Madsbjerg, Brendan May, and Stephen Jurvetson 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 HALL, ANDREW GREIG, SHEILA KHAMA, ANDREI KARKAR, CHRISTIAN MADSBJERG, BRENDAN MAY, AND STEPHEN JURVETSON 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, 2025. 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, 2024. 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, 2025.

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, 2024 and 2023, and fees billed for other services rendered by EY during those periods.

(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:

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.

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.

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.

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

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
AMENDMENT TO THE ARTICLES OF THE COMPANY
(Notice Item 4)

The board of directors proposes that the Articles of the Company be amended to remove from Article 15.8 of the Articles the outdated address of the registered office of the Company in Vancouver, British Columbia, Canada, which recently changed from 595 Howe Street, 10th Floor, Vancouver, British Columbia, V6C 2T5 Canada to 1111 West Hastings Street, 15th Floor, Vancouver, British Columbia, V6E 2J3 Canada. Part 15 of the Articles sets out the “advance notice requirements” for shareholders to nominate persons for election as directors at a meeting of our shareholders and Article 15.8 stipulates the requirements for giving notices required by Part 15. The proposed amendment to the Articles of the Company in respect of this Proposal No. 4 is set out below, marked to show the proposed changes, which removes the reference to a specific address in the Articles to avoid needing to amend the Articles in the future if the registered address changes again.

“15.8 Delivery of Notice. Notwithstanding any other provision in this Part 15, notice given to the Corporate Secretary of the Company pursuant to this Part 15 may only be given by personal delivery, facsimile transmission or email (provided that the Corporate Secretary has stipulated an e-mail address for purposes of this Part 15), and shall be deemed to have been given and received only at the time it is served by personal delivery or sent by facsimile transaction transmission (provided that receipt of confirmation of such transmission has been received) or by e-mail (at the address as foresaid aforesaid) to the Corporate Secretary at the registered office of the Company as follows: 10th Floor, 595 Howe Street, Vancouver, British Columbia, V6C 2T5 Canada Fax:, or if by facsimile at +1 604 687-8772, provided that if such delivery or electronic transmission is made on a day which is not a business day or later than 5:00 p.m. (Vancouver time) on a day which is a business day, then such delivery or electronic transmission shall be deemed to have been made on the subsequent day that is a business day.”

To approve the adoption of the following as an ordinary resolution.

BE IT RESOLVED AS AN ORDINARY RESOLUTION THAT:

The existing Articles of the Company be amended by deleting the existing Article 15.8 in its entirety and replacing it with the following Article 15.8:

“15.8 Delivery of Notice. Notwithstanding any other provision in this Part 15, notice given to the Corporate Secretary of the Company pursuant to this Part 15 may only be given by personal delivery, facsimile transmission or email (provided that the Corporate Secretary has stipulated an e-mail address for purposes of this Part 15), and shall be deemed to have been given and received only at the time it is served by personal delivery or sent by facsimile transmission (provided that receipt of confirmation of such transmission has been received) or by e-mail (at the address as aforesaid) to the Corporate Secretary at the registered office of the Company, or if by facsimile at +1 604 687-8772, provided that if such delivery or electronic transmission is made on a day which is not a business day or later than 5:00 p.m. (Vancouver time) on a day which is a business day, then such delivery or electronic transmission shall be deemed to have been made on the subsequent day that is a business day.”

Pursuant to subsection 139(c) of the Business Corporations Act (British Columbia), the board of directors of the Company are authorized to revoke this resolution or any part of it at any time before it is acted upon, without further approval of the shareholders of the Company.

Any one Director or Officer of the Company is, and the agents of the Company are, hereby authorized and directed for and on behalf of the Company to execute and deliver, under the corporate seal of the Company or otherwise, the Articles and all such other documents and instruments and to do all such other acts and things as in his or her opinion may be necessary or desirable to give full effect to the above resolutions.

A copy of our current Articles prior to the proposed amendment of the Articles set forth in the foregoing resolutions is filed as Exhibit 3.2 to our Annual Report on Form 10-K for the year ended

December 31, 2024, as filed with the SEC and available at www.sec.gov, or in the “Investors — SEC Filings” section of our website at https://metals.co.

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.

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, 2024, with the exception of a Form 4 filed on behalf of executive officer Erika Ilves on January 3, 2025 for a transaction that occurred on December 30, 2024.

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 2026 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 19, 2025. 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 2026, must be submitted to us at our registered office, on or before February 28, 2026 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 2026, although not included in the management information circular (or proxy statement), must be made not less than 30 days prior to the date of the annual general meeting of our shareholders to be held during 2026; provided, that if the first public announcement of the date of the annual general meeting of our shareholders to be held during 2026 (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 2026 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 30, 2026.
