June 14, 2022

This Proxy Statement is being furnished to the stockholders of MP Materials Corp. (the “Company,” “MP Materials” or “MP”) in connection with the solicitation of proxies for the Company’s 2022 Annual Meeting of Stockholders (the “Annual Meeting”) to be held on June 14, 2022 at 10:30 a.m., Pacific Time, or at any adjournment or postponement thereof, for the purposes set forth herein and in the accompanying Notice of Internet Availability of Proxy Materials (the “Internet Notice”). The Annual Meeting will be held via live audio webcast on the Internet at www.virtualshareholdermeeting.com/MP2022. This solicitation is being made by the Board of Directors of the Company (the “Board of Directors” or the “Board”). You will be able to vote and submit questions online through the virtual meeting platform during the Annual Meeting.

As permitted by the rules of the Securities and Exchange Commission (the “SEC”), we are making this Proxy Statement, the Internet Notice, the accompanying proxy card, and the Annual Report on Form 10-K for the fiscal year ended December 31, 2021, available to our stockholders electronically via the Internet at www.proxyvote.com.

If you received an Internet Notice by mail, you will not receive a printed copy of the proxy materials in the mail unless you specifically request them pursuant to the instructions provided in the Internet Notice. The Internet Notice instructs you on how to access and review all of the important information contained in this Proxy Statement.

THE INFORMATION PROVIDED IN THE “QUESTIONS AND ANSWERS” FORMAT BELOW IS FOR YOUR CONVENIENCE AND INCLUDES ONLY A SUMMARY OF CERTAIN INFORMATION CONTAINED IN THIS PROXY STATEMENT. YOU SHOULD READ THIS ENTIRE PROXY STATEMENT CAREFULLY.

QUESTIONS AND ANSWERS

Why am I receiving these materials?

We are distributing our proxy materials because our Board is soliciting your proxy to vote at the Annual Meeting. This Proxy Statement summarizes the information you need to vote at the Annual Meeting. You do not need to attend the Annual Meeting to vote your shares.

Pursuant to SEC rules, we are providing access to our proxy materials via the Internet at www.proxyvote.com. Accordingly, we are sending an Internet Notice to all of our stockholders as of the close of business on April 18, 2022 (the “Record Date”). All stockholders may access our proxy materials on the website referred to in the Internet Notice. You may also request to receive a printed set of the proxy materials. You can find instructions regarding how to access our proxy materials via the Internet and how to request a printed copy in the Internet Notice. Additionally, by following the instructions in the Internet Notice, you may request to receive proxy materials in printed form by mail or electronically by email on an ongoing basis. We believe that these rules allow us to provide our stockholders with the information they need while lowering the costs of delivery and reducing the environmental impact of the Annual Meeting.

How can I attend the Annual Meeting?

Stockholders as of the Record Date (or their duly appointed proxy holder) may attend, vote and submit questions virtually during the Annual Meeting by logging in at http://www.virtualshareholdermeeting.com/MP2022. To log in, stockholders (or their authorized representatives) will need the control number provided on their proxy card, voting instruction form or Internet Notice. If you are not a stockholder or do not have a control number, you may still access the meeting as a guest, but you will not be able to submit questions or vote at the meeting. The meeting will begin promptly at 10:30 a.m., Pacific Time, on Tuesday, June 14, 2022. We encourage you to access the meeting prior to the start time. Online access will open at 10:15 a.m., Pacific Time, and you should allow ample time to log in to the meeting webcast and test your computer audio system. We recommend that you carefully review the procedures needed to gain admission in advance. A recording of the meeting will be available at http://www.virtualshareholdermeeting.com/MP2022 for 90 days after the meeting.

Can I ask questions at the virtual Annual Meeting?

Stockholders as of the Record Date who attend and participate in our virtual Annual Meeting will have an opportunity to submit questions live via the Internet during a designated portion of the meeting. We also encourage you to submit questions in advance of the meeting until 11:59 p.m. Eastern Time the day before the Annual Meeting by going to www.proxyvote.com and logging in with your control number. During the meeting, we will spend up to 15 minutes answering stockholder questions that comply with the meeting rules of procedure. The rules of procedure, including the types of questions that will be accepted, will be posted on the Annual Meeting website. To ensure the orderly conduct of the Annual Meeting, we encourage you to submit questions in advance. If we receive substantially similar questions, we will group such questions together and provide a single response to avoid repetition. Stockholders must have available their control number provided on their proxy card, voting instruction form or Internet Notice to ask questions during the meeting.

What if I have technical difficulties or trouble accessing the virtual Annual Meeting?

We will have technicians ready to assist you with any technical difficulties you may have accessing the virtual meeting. If you encounter any difficulties accessing the virtual meeting during check-in or during the meeting,

please call the technical support number that will be posted on the virtual shareholder meeting login page: http://www.virtualshareholdermeeting.com/MP2022.

What proposals will be voted on at the Annual Meeting?

Stockholders will vote on four proposals at the Annual Meeting:

• the election of the three Class II directors named in this Proxy Statement to serve until the 2025 annual meeting of stockholders and until their respective successors are duly elected and qualified or until such director’s earlier death, resignation or removal;

• the ratification of the appointment of KPMG LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2022;

• an advisory vote to approve the compensation paid to the Company’s named executive officers; and

• an advisory vote on the frequency of future advisory votes on the compensation of the Company’s named executive officers.

We will also consider other business, if any, that properly comes before the Annual Meeting.

What happens if other business not discussed in this Proxy Statement comes before the meeting?

The Company does not know of any business to be presented at the Annual Meeting other than the proposals discussed in this Proxy Statement. If other business properly comes before the meeting under our Amended and Restated Certificate of Incorporation (the “Charter”), Amended and Restated Bylaws (the “Bylaws”), and rules established by the SEC, the proxies will use their discretion in casting all of the votes that they are entitled to cast.

How does the Board recommend that stockholders vote on the proposals?

Our Board recommends that stockholders vote “FOR” the election of the three director nominees named in this Proxy Statement, “FOR” the ratification of the appointment of KPMG LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2022, “FOR” the approval, on an advisory basis, of the compensation of the Company’s named executive officers, and for “1 YEAR” for the frequency of future advisory votes on compensation of the Company’s named executive officers.

Who is entitled to vote?

As of the Record Date, 177,526,623 shares of common stock, par value $0.0001 per share, were outstanding. Only holders of record of our common stock as of the Record Date will be entitled to notice of, and to vote at, the Annual Meeting or any adjournment or postponement thereof. Each stockholder is entitled to one vote for each share of our common stock held by such stockholder on the Record Date.

How do I vote in advance of the Annual Meeting?

If you are a holder of record of shares of common stock of the Company, you may direct your vote without attending the Annual Meeting by following the instructions on the Internet Notice or proxy card to vote by Internet or by telephone, or by signing, dating and mailing a proxy card.

If you hold your shares in street name via a broker, bank or other nominee, you may direct your vote without attending the Annual Meeting by signing, dating and mailing your voting instruction card. Internet or telephonic voting may also be available. Please see your voting instruction card provided by your broker, bank or other nominee for further details.

6

How do I vote during the Annual Meeting?

Shares held directly in your name as the stockholder of record may be voted if you are attending the Annual Meeting by entering the 16-digit control number found on your proxy card or Internet Notice when you log into the meeting at http://www.virtualshareholdermeeting.com/MP2022.

Shares held in street name through a brokerage account or by a broker, bank or other nominee may be voted at the Annual Meeting by entering the 16-digit control number found on your Internet Notice or voter instruction card when you log into the meeting at http://www.virtualshareholdermeeting.com/MP2022.

Even if you plan to attend the Annual Meeting, we recommend that you vote in advance, as described above under “How do I vote in advance of the Annual Meeting?” so that your vote will be counted if you are unable to attend the Annual Meeting.

Can I change my vote or revoke my proxy?

You may change your vote or revoke your proxy at any time before it is voted at the Annual Meeting. If you are a stockholder of record, you may change your vote or revoke your proxy by:

• delivering to the attention of the Secretary at the address on the first page of this Proxy Statement a written notice of revocation of your proxy;

• delivering to us an authorized proxy bearing a later date (including a proxy over the Internet or by telephone); or

• attending the Annual Meeting and voting electronically, as indicated above under “How do I vote during the Annual Meeting?” Attendance at the Annual Meeting will not, by itself, revoke a proxy.

If your shares are held in the name of a bank, broker or other nominee, you may change your vote by submitting new voting instructions to your bank, broker or other nominee. Please note that if your shares are held of record by a bank, broker or other nominee, and you decide to attend and vote at the Annual Meeting, your vote at the Annual Meeting will not be effective unless you present a legal proxy, issued in your name from the record holder (your bank, broker or other nominee).

What is a broker non-vote?

Brokers, banks or other nominees holding shares on behalf of a beneficial owner may vote those shares in their discretion on certain “routine” matters even if they do not receive timely voting instructions from the beneficial owner. With respect to “non-routine” matters, the broker, bank or other nominee is not permitted to vote shares for a beneficial owner without timely received voting instructions. The only routine matter to be presented at the Annual Meeting is the proposal to ratify the appointment of KPMG LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2022 (Proposal Two). Proposals One, Three and Four are non-routine matters.

A broker non-vote occurs when a broker, bank or other nominee does not vote on a non-routine matter because the beneficial owner of such shares has not provided voting instructions with regard to such matter. A broker, bank or other nominee may exercise its discretionary voting authority on Proposal Two because Proposal Two is a routine matter, and as such there will be no broker non-votes on Proposal Two. Broker non-votes may occur as to Proposals One, Three and Four, or any other non-routine matters that are properly presented at the Annual Meeting. Broker non-votes will have no impact on the voting results for Proposals One, Three and Four, or any other non-routine matter that comes before the Annual Meeting.

What constitutes a quorum?

The presence at the Annual Meeting, either in person or by proxy, of holders of a majority of the aggregate number of shares of our issued and outstanding common stock entitled to vote thereat as of the Record Date shall

7

constitute a quorum for the transaction of business at the Annual Meeting. Abstentions and broker non-votes will be counted as present for the purpose of determining whether there is a quorum at the Annual Meeting. Your shares are counted as being present if you participate virtually at the Annual Meeting and cast your vote online during the meeting prior to the closing of the polls by visiting http://www.virtualshareholdermeeting.com/MP2022, or if you vote by proxy via the Internet, by telephone or by returning a properly executed and dated proxy card or voting instruction form by mail.

What vote is required to approve each matter to be considered at the Annual Meeting?

Proposal One: Election of the Three Class II Directors Named in this Proxy Statement.

Our Bylaws provide that the election of directors shall be determined by a plurality of the votes cast by the stockholders present in person or represented by proxy at the meeting and entitled to vote thereon. This means that once a quorum has been established, the director nominees receiving the highest number of votes are elected up to the maximum number of directors to be elected at the meeting. Thus, the nominees receiving the highest number of votes at the Annual Meeting will be elected, even if these votes do not constitute a majority of the votes cast. A broker non-vote on Proposal One will not have any effect.

Proposal Two: Ratification of the Appointment of KPMG LLP as our Independent Registered Public Accounting Firm for the Fiscal Year Ending December 31, 2022.

The proposal to ratify the appointment of KPMG LLP as the Company’s independent registered public accounting firm for the 2022 fiscal year requires approval by the affirmative vote of a majority of the votes cast by the stockholders present in person or represented by proxy at the meeting and entitled to vote thereon with respect to such proposal. An abstention on Proposal Two will have no effect. Brokers will have discretionary authority to vote on this proposal. Accordingly, there will not be any broker non-votes on Proposal Two.

Proposal Three: Advisory Vote to Approve Compensation Paid to the Company’s Named Executive Officers.

The proposal to approve an advisory resolution regarding the compensation of the Company’s named executive officers requires approval by the affirmative vote of a majority of the votes cast by the stockholders present in person or represented by proxy at the meeting and entitled to vote thereon with respect to such proposal. An abstention or a broker non-vote on Proposal Three will not have any effect.

Proposal Four: Advisory Vote on the Frequency of Future Advisory Votes on Executive Compensation.

For the proposal to act upon an advisory vote on the frequency of future advisory votes on the compensation of the Company’s named executive officers, the frequency of every year, two years, or three years that receives the affirmative vote of a majority of the votes cast by the stockholders present in person or represented by proxy at the meeting and entitled to vote thereon will be the frequency recommended by our stockholders for future advisory votes on the compensation of the Company’s named executive officers. An abstention or a broker non-vote on Proposal Four will not have any effect.

What is the deadline for submitting a proxy?

To ensure that proxies are received in time to be counted prior to the Annual Meeting, proxies submitted by Internet or by telephone should be received by 11:59 p.m. Eastern Time on June 13, 2022, and proxies submitted by mail should be received by the close of business on June 13, 2022 (the day prior to the date of the Annual Meeting).

What does it mean if I receive more than one Internet Notice or proxy card?

If you hold your shares in more than one account, you will receive an Internet Notice or proxy card for each account. To ensure that all of your shares are voted, please complete, sign, date and return a proxy card for each account or use the Internet Notice or proxy card for each account to vote by Internet or by telephone.

8

How will my shares be voted if I return a blank proxy card or a blank voting instruction card?

If you are a holder of record of our common stock and you sign and return a proxy card or otherwise submit a proxy without giving specific voting instructions, your shares will be voted:

• “FOR” the election of the three Class II directors named in this Proxy Statement;

• “FOR” the ratification of the appointment of KPMG LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2022;

• “FOR” the approval, on an advisory basis, of the compensation of the Company’s named executive officers; and

• For “1 YEAR” for the frequency of future advisory votes on compensation of the Company’s named executive officers.

If you hold your shares in street name via a broker, bank or other nominee and do not provide the broker, bank or other nominee with voting instructions (including by signing and returning a blank voting instruction card), your shares:

• will be counted as present for purposes of establishing a quorum;

• will be voted in accordance with the broker’s, bank’s or other nominee’s discretion on “routine” matters, which includes the proposal to ratify the appointment of KPMG LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2022 (Proposal Two); and

• will not be counted in connection with the election of the Class II director nominees named in this Proxy Statement (Proposal One), the approval, on an advisory, of the compensation of the Company’s named executive officers (Proposal Three), and for “1 Year” for the frequency of future advisory votes on compensation of the Company’s named executives (Proposal Four) or any other non-routine matters that are properly presented at the Annual Meeting. For each of these proposals, your shares will be treated as “broker non-votes.” A broker non-vote will have no impact on voting results for non-routine matters.

Our Board knows of no matter to be presented at the Annual Meeting other than Proposals One, Two, Three and Four. If any other matters properly come before the Annual Meeting upon which a vote properly may be taken, shares represented by all proxies received by us will be voted with respect thereto as permitted and in accordance with the judgment of the proxy holders.

Who is making this solicitation and who will pay the expenses?

This proxy solicitation is being made on behalf of our Board. The Company will pay the cost of soliciting proxies for the Annual Meeting. In addition to solicitation by mail, our employees may solicit proxies personally or by telephone or facsimile, but they will not receive additional compensation for these services. Arrangements may be made with brokerage houses, custodians, nominees and fiduciaries to send proxy materials to their principals and we may reimburse them for their expenses. We have retained D.F. King & Co., Inc. to assist in the solicitation of proxies at a cost that is not expected to exceed $17,500 plus reasonable out-of-pocket expenses.

Will a stockholder list be available for inspection?

A list of stockholders entitled to vote at the Annual Meeting will be available for inspection by stockholders for any purpose germane to the meeting for 10 business days prior to the Annual Meeting, at MP Materials Corp., 6720 Via Austi Parkway, Suite 450, Las Vegas, Nevada 89119, between the hours of 9:00 a.m. and 5:00 p.m. Pacific Time. The stockholder list will also be available to stockholders of record for examination during the Annual Meeting at http://www.virtualshareholdermeeting.com/MP2022. You will need the control number included on your Internet Notice, proxy card, or voting instruction form, or otherwise provided by your bank, broker or other nominee.

9

What is “householding” and how does it affect me?

We have adopted a procedure approved by the SEC called “householding.” Under this procedure, we send only one Proxy Statement, Internet Notice and one Annual Report to eligible stockholders who share a single address, unless we have received instructions to the contrary from any stockholder at that address. This practice is designed to eliminate duplicate mailings, conserve natural resources, and reduce our printing and mailing costs. Stockholders who participate in householding will continue to receive separate proxy cards.

If you share an address with another stockholder and receive only one set of proxy materials but would like to request a separate copy of these materials, please contact our mailing agent, Broadridge, by calling (866) 540-7095 or writing to Broadridge Householding Department, 51 Mercedes Way, Edgewood, NY 11717, and an additional copy of proxy materials will be promptly delivered to you. Similarly, if you receive multiple copies of the proxy materials and would prefer to receive a single copy in the future, you may also contact Broadridge at the above telephone number or address. If you own shares through a bank, broker, or other nominee, you should contact the nominee concerning householding procedures.

How can I find out the results of the voting at the Annual Meeting?

We will announce preliminary voting results at the Annual Meeting. We will also disclose voting results on a Current Report on Form 8-K that we will file with the SEC within four business days after the Annual Meeting.

When are stockholder proposals due for next year’s annual meeting of the stockholders?

Recommendation of Our Board of Directors

OUR BOARD OF DIRECTORS RECOMMENDS THAT OUR STOCKHOLDERS VOTE “FOR” THE ELECTION OF THE THREE CLASS II NOMINEES NAMED ABOVE.

13

CORPORATE GOVERNANCE

Classified Board of Directors

Our Board is divided into three classes of directors that serve staggered three-year terms. At each annual meeting of stockholders, a class of directors is elected for a three-year term to succeed the same class whose term is then expiring. As a result, only one class of directors will be elected at each annual meeting of stockholders, with the other classes continuing for the remainder of their respective three-year terms.

Each director’s term continues until its expiration and until the election and qualification of his or her successor, or his or her earlier death, resignation or removal. Our Charter and Bylaws authorize only our Board to fill vacancies on our Board. The Board intends that any increase or decrease in the number of directors will be distributed among the three classes so that, as nearly as possible, each class will consist of one-third of the directors. This classification of our Board may have the effect of delaying or preventing changes in control of our Company.

Director Independence

Our common stock is listed on the New York Stock Exchange (the “NYSE”). Under the rules of the NYSE, independent directors must comprise a majority of a listed company’s board of directors within a specified period of the completion of its initial public offering. In addition, the rules of the NYSE require that, subject to specified exceptions, each member of a listed company’s audit, compensation, and nominating and corporate governance committees be independent. Under the rules of the NYSE, a director will only qualify as an “independent director” if the director has no material relationship with the listed company, broadly taking into consideration all relevant facts and circumstances.

Audit Committee members must also satisfy the independence criteria set forth in Rule 10A-3 under the Exchange Act. In order to be considered independent for purposes of Rule 10A-3, a member of an audit committee of a listed company may not, other than in his or her capacity as a member of the audit committee, the board of directors or any other board committee: (1) accept, directly or indirectly, any consulting, advisory or other compensatory fee from the listed company or any of its subsidiaries or (2) be an affiliated person of the listed company or any of its subsidiaries.

At least annually, our Board evaluates all relationships between us and each director in light of relevant facts and circumstances for the purposes of determining whether a material relationship exists that might signal a potential conflict of interest or otherwise interfere with such director’s ability to satisfy his or her responsibilities as an independent director. Based on this evaluation, our Board will make an annual determination of whether each director is independent within the meaning of the independence standards of the NYSE and the SEC.

Our Board has determined that each of Messrs. McKnight, Weisenburger and Gold, General Myers and Mses. Lavan and Duckworth qualifies as an “independent director” as defined under the rules of the NYSE. Mr. Litinsky, who serves as our Chairman and CEO, is not independent. Our Board also has determined that Mr. Weisenburger, and Mses. Duckworth and Lavan, who comprise our Audit Committee, Messrs. McKnight, Weisenburger and Gold, who comprise our Compensation Committee, and Mses. Duckworth and Lavan, and General Myers, who comprise our Nominating and Corporate Governance Committee, satisfy the independence standards for such committees established by the SEC and the rules of the NYSE, as applicable. In making such determinations, our Board considered the relationships that each such non-employee director has with our Company and all other facts and circumstances our Board deemed relevant in determining independence, including the beneficial ownership of our capital stock by each non-employee director and any institutional stockholder with which he or she is affiliated.

Board Leadership Structure

Our Corporate Governance Guidelines provide the Board will determine the Board leadership structure in a manner that it determines to be in the best interests of the Company and its stockholders. The Chairman of the Board and CEO positions may, but need not be, filled by the same individual.

14

At this time, the offices of the Chairman of the Board and the CEO are combined, with Mr. Litinsky serving as the Company’s Chairman and CEO. The Board believes that combining the Chairman and CEO positions is the

appropriate corporate governance structure for the Company at this time because it most effectively utilizes Mr. Litinsky’s extensive experience and knowledge of the Company and the industry, and provides for the most efficient leadership of our Board and Company. Board governance is balanced with a strong Presiding Director position, which is designed to maintain the Board’s firm independent oversight.

As Presiding Director, Mr. Weisenburger has the following duties:

• serve as a liaison between the Chairman of the Board and the independent directors;

• lead any executive sessions of the Board;

• preside at, and chair, Board meetings and meetings of stockholders at which the Chairman of the Board is absent;

• serve as temporary Chairperson of the Board in the event of the inability of the Chairperson of the Board to fulfill his/her role due to crisis or other event or circumstance which would make leadership by existing management inappropriate or ineffective, in which case the Presiding Director shall have the authority to convene meetings of the Board;

• collaborate with the Chairman of the Board on the frequency of Board meetings and any need for special Board meetings, if required;

• have authority to call meetings of the independent directors;

• lead the Board in discussions concerning the CEO’s performance and CEO succession;

• together with the Chairman of the Board, approve meeting agendas and meeting schedules for the Board;

• together with the Chairman of the Board, approve information sent to the Board, as necessary;

• serve as a liaison for stockholders who request direct communications with the Board;

• recommend to the Board, in concert with the chairpersons of the respective Board committees, the retention of consultants and advisors who directly report to the Board, including such independent legal, financial or other advisors as he or she deems appropriate, without consulting or obtaining the advance authorization of any officer of the Company; and

• perform such other duties and responsibilities as requested by the Board.

Role of the Board in Risk Oversight

The Board is responsible for the oversight of risk, while management is responsible for the day-to-day management of risk. The Board, directly and through its committees, carries out its oversight role by regularly reviewing and discussing with management the risks inherent in the operation of our business and applicable risk mitigation efforts. Management meets regularly to discuss the Company’s business strategies, challenges, risks and opportunities and reviews those items with the Board at regularly scheduled meetings. The Compensation Committee is responsible for overseeing the management of risks relating to our compensation plans and arrangements, including whether the Company’s incentive compensation plans encourage excessive or inappropriate risk taking. The Audit Committee is responsible for overseeing our risk assessment and management processes related to, among other things, cybersecurity, environmental, social and governance (ESG) matters, our financial reports and record-keeping, major litigation and financial risk exposures and the steps management has taken to monitor and control such exposures. The Nominating and Corporate Governance Committee is responsible for risk oversight associated with corporate governance practices and the composition of our Board and its committees.

15

Evaluations of the Board of Directors

Under our Corporate Governance Guidelines, the Board evaluates its performance and the performance of its committees and individual directors on an annual basis through an evaluation process administered by our Nominating and Corporate Governance Committee. The Board discusses each evaluation to determine what, if any, actions should be taken to improve the effectiveness of the Board or any committee thereof or of the directors.

Board and Committee Meetings and Attendance

Directors are expected to make every effort to attend all meetings of the Board and all meetings of the committees on which they serve. During fiscal 2021, our Board had seven Board meetings. During fiscal 2021, each member of our Board attended at least 75% of all Board and relevant Committee meetings held during the period in which such director served. Our independent directors hold regularly scheduled executive sessions without our management present. These executive sessions of independent directors are chaired by our Presiding Director.

Board Attendance at Annual Stockholders’ Meeting

Each director is encouraged and generally expected to attend the Company’s annual meeting of stockholders. Each of our directors attended the Company’s 2021 Annual Meeting of Stockholders.

Board Committees

Our Board has established an Audit Committee, a Compensation Committee and a Nominating and Corporate Governance Committee. The composition and responsibilities of each of the committees of our Board are described below. Copies of the charters of the committees, our Corporate Governance Guidelines and our Code of Business Conduct and Ethics are available on the investor relations page of our website at https://investors.mpmaterials.com/governance/governance-documents/default.aspx. The information in or accessible through our website is not incorporated into, and is not considered part of, this Proxy Statement. Members serve on these committees until their resignation or until otherwise determined by our Board. Our Board may establish other committees as it deems necessary or appropriate from time to time.

The following table provides membership and meeting information for 2021 for each of these committees of our Board with directors marked with an asterisk (*) identified as committee chair:

Audit Committee

Randall J. Weisenburger, Connie K. Duckworth, and Maryanne R. Lavan are the members of the Audit Committee. Mr. Weisenburger is the Chairman of the Audit Committee.

16

Rule 10A-3 of the Exchange Act. Our Board has determined that Mr. Weisenburger qualifies as an “audit committee financial expert” as such term is defined in Item 407(d)(5) of Regulation S-K, and that each of the members is financially literate, as defined under the rules of the NYSE. Under its charter, the functions of the Audit Committee include, among other things:

All of the members of the Compensation Committee are independent directors and are considered to be a “non-employee director” under Rule 16b-3 of the Exchange Act.

Under its charter, the functions of the Compensation Committee include reviewing and approving annually the evaluation process and compensation structure for the Company’s or its subsidiaries’ officers; and evaluating, reviewing and recommending to the Board any changes to, or additional, stock-based and other incentive compensation plans.

The Compensation Committee charter also provides that the Compensation Committee shall have the sole authority to retain or obtain the advice of a compensation consultant, legal counsel or other adviser. However, before engaging or receiving advice from a compensation consultant, external legal counsel or any other adviser, the Compensation Committee will consider the independence of each such adviser, including the factors required by NYSE and the SEC.

17

Nominating and Corporate Governance Committee

Connie K. Duckworth, General Richard B. Myers, and Maryanne R. Lavan are members of the Nominating and Governance Committee. Ms. Duckworth is the Chairperson of the Nominating and Corporate Governance Committee. All of the members of the Nominating and Governance Committee are independent directors.

Under its charter, the functions of the Nominating and Corporate Governance Committee include, among other things:

• identifying individuals qualified to become a member of the Board in the event of a vacancy on the Board and recommending to the Board the director nominees for the next annual meeting of stockholders;

• reviewing periodically the committee structure of the Board and recommending to the Board any changes to committee structure, the appointment of directors to Board committees and the assignment of committee chairs;

• developing and recommending to the Board a code of business conduct and ethics applicable to the Company and monitoring compliance with such code, including review of conflicts of interest or waivers;

The Nominating and Corporate Governance Committee has the sole authority to retain and terminate any search firm to be used to identify director candidates and shall have sole authority to approve the search firm’s fees and other retention terms. In addition, on a periodic basis, the Nominating and Corporate Governance Committee will conduct an in-depth, broad scope and detailed review of succession planning efforts of the Company’s management team.

The Nominating and Corporate Governance Committee has not set specific minimum qualifications for director positions. Instead, the Nominating and Corporate Governance Committee will review nominations for election or re-election to the Board on the basis of a particular candidate’s merits and the Company’s needs after taking into account the current composition of the Board. When evaluating candidates annually for nomination for election, the Nominating and Corporate Governance Committee will consider an individual’s skills, diversity, independence, experience in areas that address the needs of the Board and ability to devote adequate time to Board duties. The Nominating and Corporate Governance Committee does not specifically define diversity, but values diversity of experience, perspective, education, race, gender and national origin as part of its overall annual evaluation of director nominees for election or re-election. Whenever a new seat or a vacated seat on the Board is being filled, candidates that appear to best fit the needs of the Board and the Company will be identified, interviewed and evaluated by the Nominating and Corporate Governance Committee. Potential director candidates recommended by the Company’s management and stockholders are evaluated in the same manner as nominees identified by the Nominating and Corporate Governance Committee. Candidates selected by the Nominating and Corporate Governance Committee will then be recommended to the full Board.

Corporate Governance Guidelines

Our Board has adopted Corporate Governance Guidelines, which provide the framework for our corporate governance along with our Charter, Bylaws, committee charters and other key governance practices and policies.

18

Our Corporate Governance Guidelines cover a wide range of subjects, including the conduct of Board meetings, independence and selection of directors, Board membership criteria, and Board committee composition.

Code of Business Conduct and Ethics

The Company has adopted a Code of Business Conduct and Ethics applicable to its directors, executive officers and employees and a Code of Ethics for Senior Executive and Financial Officers that comply with the rules and regulations of the NYSE. The Code of Business Conduct and Ethics codifies the business and ethical principles that govern all aspects of the Company’s business. Copies of the Code of Business Conduct and Ethics and the Code of Ethics for Senior Executive and Financial Officers are available at https://investors.mpmaterials.com/governance/governance-documents/default.aspx. If we ever were to amend or waive any provision of our Code of Ethics for Senior Executive and Financial Officers that applies to our directors or executive officers, we intend to satisfy our disclosure obligations with respect to any such waiver or amendment by posting such information on our internet website set forth above rather than by filing a Form 8-K. The information in or accessible through our website is not incorporated into, and is not considered part of, this Proxy Statement.

Stock Ownership by Directors

The Board believes that an ownership stake in the Company strengthens the alignment of interests between directors and stockholders. The Board has adopted stock ownership guidelines requiring each non-employee and non-affiliated director that participates in our non-employee and non-affiliated director compensation program to own common stock (or equivalents) having a value of at least five times the annual cash retainer fee, within five years of becoming a director, which shall be maintained through such director’s term of service. In the event that the annual cash retainer fee is increased, non-employee and non-affiliated directors will have five years to meet the new ownership guidelines. Until the required ownership guideline is reached, non-employee directors are required to retain at least 50% of the net profit shares acquired from the vesting or exercise of their awards. The Compensation Committee will periodically review the ownership and holding requirements for non-employee and non-affiliated directors and make recommendations to the Board with regard to any changes. As of the date of this Proxy Statement, each of the non-employee directors exceeds the targeted ownership pursuant to the stock ownership guidelines.

Prohibition on Hedging and Pledging of Company Securities

The Company has a policy that prohibits officers, directors and employees from engaging in hedging transactions, such as the purchase or sale of puts or calls, or the use of any other derivative instruments. Officers, directors and employees of the Company are also prohibited from holding Company securities in a margin account or pledging Company securities as collateral for a loan without the approval of the Board.

Stockholder Communications

Any stockholder or other interested party who wishes to communicate with our Board or any individual director may send written communications to our Board or such director c/o MP Materials Corp., 6720 Via Austi Parkway, Suite 450, Las Vegas, Nevada 89119, Attention: Secretary. Our Secretary shall initially review and compile all such communications and may summarize such communications prior to forwarding to the appropriate party. Our Secretary will not forward communications that are not relevant to the duties and responsibilities of the Board. The Board will generally respond, or cause the Company to respond, in writing to bona fide communications from stockholders addressed to one or more members of the Board.

Director Nominations by Stockholders

Nominations of persons for election to the Board may be made by any stockholder of the Company who is a stockholder of record and complies with the notice procedures set forth in the Bylaws, and such nominations must be accompanied by a written consent from the proposed nominee to being named as a nominee and to serve as a director if elected. All candidates, regardless of the source of their recommendation, are evaluated in the same manner as nominees identified by the Nominating and Corporate Governance Committee.

19

Amended and Restated Offtake Agreement with Shenghe Resources Holding Co., Ltd. and Affiliated Persons/Entities

We entered into an amended and restated offtake agreement with Shenghe Resources (Singapore) International Trading Pte. Ltd., an affiliate of Shenghe Resources Holding Co., Ltd. and Leshan Shenghe on May 19, 2020 (the “A&R Offtake Agreement”). As of the Record Date, Shenghe Resources Holding Co., Ltd. is the beneficial owner of approximately 7.7% of our common stock. See “Security Ownership of Certain Beneficial Owners and Management.” Shenghe Resources Holding Co., Ltd. and its affiliates are referred to herein individually and collectively as “Shenghe.”

Pursuant to the terms of the A&R Offtake Agreement, we sold the vast majority of our rare earth concentrate to Shenghe. Shenghe was contractually obligated under the A&R Offtake Agreement to purchase all of our rare earth concentrate product meeting certain minimum specifications on a “take-or-pay basis” (such that they were obliged to pay for product even if they were unable or unwilling to take delivery). Shenghe sold the rare earth concentrate it acquired under the A&R Offtake Agreement to customers in China, which processed and resold these refined products.

Under the A&R Offtake Agreement, Shenghe was entitled to retain their gross profits from the sales of our products, and those gross profits were credited against the prepaid balance, which is money Shenghe advanced to us fund the restart of operations at the mine and additional operating and capital expenditures to bring Mountain

20

Pass to full operability. When Shenghe recouped all of the repaid the prepaid balance, the A&R Offtake Agreement terminated. As of December 31, 2021, the amount outstanding on the prepaid balance was $16.6 million, which was repaid in full in March 2022 and the A&R Offtake Agreement terminated.

On March 4, 2022, we entered into a new offtake agreement, dated as of March 4, 2022 (“2022 Offtake Agreement”) with Shenghe. Pursuant to the terms of the 2022 Offtake Agreement, the Company sells to Shenghe rare earth products produced by the Company for distribution to end users. The initial term of the 2022 Offtake Agreement is two years and the Company has the option to extend the term for an additional one-year period. As provided in the 2022 Offtake Agreement, and subject to certain exclusions, Shenghe shall purchase on a take-or-pay basis the rare earth concentrate produced by the Company as the exclusive distributor in China during the term, with certain exceptions for the Company’s direct sales globally. In addition, Shenghe shall purchase on a take-or-pay basis the certain non-concentrate rare earth products that the Company in its sole discretion nominates to Shenghe for distribution as the exclusive distributor of those certain non-concentrate rare earth products in China during the term. Further, the Company may sell all non-concentrate rare earth products in its sole discretion to customers or end users in any jurisdiction. In exchange for distribution services, Shenghe will be paid a variable commission on net proceeds to the Company.

Rare Earth Fluoride Purchase Agreement

On March 17, 2022, the Company entered into a Rare Earth Fluoride Purchase Agreement with Shenghe (the “REF Purchase Agreement”). Pursuant to the REF Purchase Agreement, the Company sells to Shenghe rare earth fluoride products that had been stockpiled at Mountain Pass for distribution to end users. The Company receives a fixed amount per metric ton of rare earth fluoride upfront and will share in any excess proceeds derived from sales to end customers after Shenghe recovers their costs of cleaning, processing, and distributing the products. The term of the REF Purchase Agreement is from March 17, 2022, and ends on the earlier of the following to occur (i) the date that the quantity of rare earth fluoride provided under the REF Purchase Agreement has been sold by Shenghe or (ii) twelve months from March 17, 2022.

Reagent Purchases

We occasionally purchase reagent products (produced by an unrelated third party) used in the milling process at the Mountain Pass facility from Shenghe. Such purchases are made on a case-by-case basis pursuant to standard purchase orders. During the fiscal year ended December 31, 2021, these purchases totaled $4.8 million.

Lab-Scale Sample Purchases

In March 2022, we agreed to purchase lab-scale samples of rare earth products from Shenghe to aid in our process development and customer development. Such purchases are made on a case-by-case basis pursuant to standard purchase orders. The purchase order was $119,550 in March 2022.

Procedures with Respect to Review and Approval of Related Person Transactions

The Board has 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 consolidated subsidiaries was, is or will be a participant, the aggregate amount of which involved will or may be expected to exceed $120,000, and in which any Related Person had, has or will have a direct or indirect material interest (including any indebtedness or guarantee of indebtedness), subject to certain exceptions as outlined in the Related Person Transaction Policy. A “Related Person” means:

• any person who is, or at any time during the applicable period was, one of the Company’s executive officers or a member or nominee of the Company’s Board of Directors;

21

• any person who is known by the Company to be the beneficial owner of more than five percent (5%) of our voting stock;

• any immediate family member of any of the foregoing persons, which means 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 a director, executive officer, director nominee or a beneficial owner of more than five percent (5%) of our voting stock, and any person (other than a tenant or employee) sharing the household of such director, executive officer, director nominee or beneficial owner of more than five percent (5%) of our voting stock; and

• any firm, corporation or other entity in which any of the foregoing persons is a partner or principal or in a similar position or in which such person has a 10 percent (10%) or greater beneficial ownership interest.

Each Related Person Transaction must be approved or ratified in accordance with the guidelines set forth in the Related Person Transaction Policy by the Audit Committee or by the disinterested members of the Board by the vote of a majority thereof, as the case may be (the “Reviewing Directors”). In considering whether to approve or ratify any Related Person Transaction, the Reviewing Directors shall consider all relevant information available concerning the Related Person Transaction, including, but not limited to: (a) the size of the transaction and the amount payable to a Related Person and the transaction’s material terms, (b) the nature of the interest of the Related Person in the transaction, (c) whether the transaction may involve a conflict of interest or would impair the ability of a director or executive officer to act in the best interests of the Company, (d) whether the transaction was undertaken in the ordinary course of business of the Company, (e) the business rationale for the transaction, (f) whether the transaction involves the provision of goods or services to the Company that are available from unaffiliated third parties and, if so, whether the transaction is on terms and made under circumstances that are at least as favorable to the Company as would be available in comparable transactions with or involving unaffiliated third parties and (g) any other information regarding the Related Person Transaction or Related Person that would be material to investors in light of the circumstances of the transaction.

In addition, in connection with any approval or ratification of a Related Person Transaction involving a non-employee director or nominee for director, the Reviewing Directors should consider whether such transaction would compromise such director’s status as (1) an independent director under NYSE Listing Rules, including any additional independence requirements specific to compensation committee membership set forth in such rules if such non-employee director serves, or such non-employee nominee will serve, on the Compensation Committee of the Board or Rule 10A-3 of the Exchange Act, if such non-employee director serves, or such nonemployee nominee will serve, on the Audit Committee of the Board of Directors; and (2) a “nonemployee director” under Rule 16b-3 under the Exchange Act, if such non-employee director serves, or such non-employee nominee will serve, on the relevant subcommittee of the Compensation Committee of the Board of Directors.

The Reviewing Directors may approve the Related Person Transaction only if they determine in good faith that, based on all of the relevant information available to them, the transaction is in, or is not inconsistent with the best interests of the Company and its stockholders. The Reviewing Directors, in their sole discretion, may impose such conditions as they deem appropriate on the Company or the Related Person in connection with the approval of the Related Person Transaction. The Reviewing Directors may also conclude, upon review of all relevant information available to them, that the transaction does not constitute a Related Person Transaction, and thus that no further review is required under the Related Person Transaction Policy.

The Company has also adopted 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. Specifically, pursuant to the Related Person Transaction Policy and in accordance with NYSE rules, the Audit Committee has the responsibility to review Related Person Transactions for potential conflicts of interest and will prohibit a transaction if it determines it to be inconsistent with the interests of the Company and its stockholders.

The compensation of the Company’s non-employee directors is paid in the form of annual retainers and an annual grant of restricted stock units. With respect to 2021, Messrs. Gold and McKnight did not receive compensation for their services on the Board. Beginning in 2022, Messrs. Gold and McKnight will receive compensation for their services on the Board. Mr. Litinsky, our Chairman and CEO, does not receive separate compensation for his service on the Board. Please see the “2021 Summary Compensation” table for the compensation received by Mr. Litinsky. During 2020, the only compensation received by members of our Board was a restricted stock unit award, pro-rated for the period of service between the closing of the Business Combination and the date of the Annual Meeting.

The fees that each non-employee director (other than Messrs. Gold, Litinsky and McKnight) or committee chair received for his or her service during 2021 were the following:

• Annual Board Cash Retainer: $60,000

• Additional Presiding Director Cash Retainer: $20,000

• Committee Member Cash Retainers:

• Audit Committee: $7,500

• Compensation Committee: $5,000

• Governance and Nominating Committee: $5,000

The number of shares underlying the annual restricted stock unit award is calculated by dividing $100,000 by the closing price of a share of our common stock on the NYSE as of the date the annual restricted stock unit award is granted. Non-employee and non-affiliated directors are also subject to stock ownership guidelines equal to five times the annual Board cash retainer. Directors have five years from becoming subject to the guidelines to achieve the required ownership level. As of the date of this Proxy Statement, each of the non-employee directors exceeds the targeted ownership pursuant to the stock ownership guidelines.

In addition, non-employee directors are permitted to defer cash retainers and receive deferred stock units in lieu of such cash fees. If a director elects to defer cash retainer fees, the director will receive stock-settled deferred stock units that will be delivered upon the earlier to occur of (i) June 15th following the fifth (5th) anniversary of the vesting date; (ii) a change in control of the Company; and (iii) the date of the director’s separation from service.

COMPENSATION DISCUSSION AND ANALYSIS

This Compensation Discussion and Analysis provides narrative disclosure regarding the compensation plans, programs and arrangements we employed for individuals serving as our Chief Executive Officer, Chief Financial Officer, and our other named executive officers, as determined under the rules of the SEC (collectively, our “named executive officers”).

During fiscal 2021, our named executive officers were:

• James H. Litinsky, Chairman of the Board and Chief Executive Officer;

• Ryan Corbett, Chief Financial Officer;

• Michael Rosenthal, Chief Operating Officer;

• Elliot D. Hoops, General Counsel and Secretary; and

Business Overview

MP Materials Corp. is the largest producer of rare earth materials in the Western Hemisphere. The Company owns and operates the Mountain Pass Rare Earth Mine and Processing Facility in California, North America’s only active and scaled rare earth production site. Separated rare earth elements are critical inputs to the world’s most powerful and efficient magnets found in electric vehicles, drones, defense systems, wind turbines and various advanced technologies. The Company is developing U.S. metal, alloy and magnet manufacturing capacity to build these critical components domestically.

Executive Compensation Philosophy and Objectives

In developing compensation plans for our named executive officers, the Compensation Committee seeks to balance all of our business characteristics and create a program that will motivate and reward named executive officers for their performance and for creating value for our stockholders over time. The Compensation Committee evaluates and revises, as necessary, our compensation program to assess whether they support our business objectives and provide competitive compensation levels for our named executive officers. The business objectives that we seek to recognize in our compensation program include:

• Focusing on prudent growth in both current and future projects;

• Maximizing operational efficiency;

• Managing cash flow for investment;

• Maximizing safety, operating profitability, and production at our Mountain Pass Mine; and

• Creating long-term value for our stockholders.

More specifically, our compensation program strives to support our business needs through the following objectives:

• Allowing us to attract and retain a high-quality management team capable of managing and growing the business for the benefit of our stockholders;

• Providing a competitive compensation program appropriate for the size and complexity of MP relative to the market for executive pay;

• Aligning actual pay results with performance for stockholders, with an opportunity to realize pay above target levels for excellent performance and below target levels for poor performance;

28

• Incentivizing management to maximize stockholder value without taking undue financial risks and while maintaining credibility in the capital markets;

• Rewarding individual contribution, in addition to team efforts; and

• Maintaining effective incentives during difficult economic environments.

Although we reference the market from time to time for competitive pay practices in setting overall target pay levels for our executives, we do not define a specific percentile of market for targeting executive pay. We consider many factors, including the actual performance and contribution of our executives, and internal pay comparisons between our executives, when determining individual executive pay, as discussed in more detail below.

Specifically, the Compensation Committee considers market information in light of their individual experience, knowledge of the Company, knowledge of the peer companies discussed below, knowledge of each named executive officer and their business judgment when making decisions regarding our executive compensation program.

Pay for Performance

MP Materials Corp. has a strong philosophy that executive pay should vary with performance in order to align executive interests with those of our stockholders over time. We believe that our executive pay system is thoughtfully designed to reinforce this philosophy and to drive value-creating financial, operating, and strategic results, while also taking our external environment into account. Our executive compensation program brings this philosophy to life by incorporating the following features:

• A significant portion of our executive incentive awards are delivered in shares of MP Materials Corp. Common Stock over the longer-term to encourage strong sustainable results over multiple years and to align the ultimate value of the award with stockholder interests;

• We have instituted clawbacks and stock ownership guidelines for executives that are intended to align our executives with our stockholders;

• Our insider trading policy prohibits executive officers and directors from hedging their ownership of MP Materials Corp. Common Stock, including transactions in puts, calls, or other derivative instruments and also prohibits executive officers and directors from placing shares of MP Common Stock in margin accounts and pledging shares of MP Common Stock without the approval of the Board; and

• We do not provide tax gross-ups in the event of a change-of-control.

Fiscal 2021 Performance Context for Compensation Decisions

MP Materials achieved record overall financial results in 2021. During 2021, we generated record revenue of $332.0 million, up 147% year over year. We also had net income of $135.0 million and Adjusted EBITDA of $219.1 million, a 414% increase year over year.

In 2021, MP Materials achieved record financial performance by producing a record 42,413 metric tons of rare earth oxides (“REO”) in concentrate (the highest rare earth production in the United States and Mountain Pass history) and selling a record 42,158 metric tons of REO. For a further discussion regarding Adjusted EBITDA and a reconciliation of net income to Adjusted EBITDA, please see Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations of the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2021, beginning on page 46.

In addition, other accomplishments for the year include the following:

• Raised $690.0 million in gross proceeds from a green convertible bond offering in March 2021;

29

• Made solid progress on Stage II optimization construction;

• Pulled forward Stage III strategy, announcing initial rare earth metal, alloy, and magnetics manufacturing facility in Fort Worth, Texas; and

• Signed long-term agreement with General Motors to supply alloy and magnets powering 12+ Ultium Platform electric vehicle models.

The Compensation Committee took each of these accomplishments and other relevant factors into account in assessing the performance of our named executive officers in 2021.

Oversight of Executive Compensation

Role of Compensation Committee

The Compensation Committee has overall responsibility for the compensation program and policies pertaining to our named executive officers. The specific responsibilities of the Compensation Committee related to executive compensation include:

• Overseeing development and implementation of our compensation plans for our named executive officers;

• Overseeing development, implementation, and administration of our equity compensation plans for executives and other employees;

• Reviewing and approving compensation for our Chief Executive Officer and other named executive officers, including setting goals and objectives, evaluating performance, verifying results, and determining pay levels;

• Overseeing regulatory compliance with respect to executive and equity compensation matters, including assessing the extent to which our compensation program could encourage undue risk-taking by executives and employees; and

• Approving, or recommending to the Board for approval when deemed appropriate, all employment, retention and/or severance agreements for named executive officers.

Role of Management in Compensation Process

The Compensation Committee relies significantly on the input and recommendations of our Chief Executive Officer when evaluating factors relative to the compensation of our named executive officers (other than the Chief Executive Officer). Our Chief Executive Officer provides the Compensation Committee with his assessment of the performance of each named executive officer and his perspective on the factors described above in developing his recommendations for each named executive officer’s compensation, including salary adjustments, equity grants and incentive bonuses. The Compensation Committee discusses our Chief Executive Officer’s recommendations, consults with its independent advisor, and then approves or modifies the recommendations in collaboration with the Chief Executive Officer.

The compensation of our Chief Executive Officer is determined by the Compensation Committee, which approves any adjustments to his base salary, performance incentive compensation and equity awards from year to year and obtains the Board’s approval (excluding the Chief Executive Officer). The Compensation Committee makes determinations regarding our Chief Executive Officer’s compensation independently and without him present. Our Chief Executive Officer attends portions of the Compensation Committee meetings, but does not attend portions of those meetings related to making specific decisions on his compensation.

In addition to recommendations put forth by our Chief Executive Officer, other members of our executive team are involved in the compensation process by assembling data to present to the Compensation Committee

30

and by working with the outside independent compensation consultants to give them the information necessary for them to complete their reports. Other members of our executive management team also occasionally attend portions of the Compensation Committee meetings, but do not attend portions of those meetings related to making specific decisions on their own compensation.

Role of Outside Consultants

The Compensation Committee retains the services of an outside independent executive compensation consultant to assess the competitiveness of our compensation program, conduct other research as directed by the Compensation Committee, and support the Compensation Committee in the design of executive and director compensation. In 2021, the Compensation Committee retained Frederic W. Cook & Co., Inc. (“FW Cook” or the “Compensation Consultant”) to assist in the review and assessment of our compensation program. FW Cook is a nationally recognized independent provider of executive compensation advisory services, with no affiliation with any other MP service provider. In 2021, FW Cook provided the Compensation Committee with assistance on a variety of matters, including a competitive assessment of compensation pertaining to its executive officers and senior management. FW Cook did not provide any other services to the Company outside of its engagement by the Compensation Committee and the Company has determined that FW Cook’s services to the Compensation Committee did not raise any conflicts of interest.

Competitive Pay Comparisons

When determining the compensation opportunity for individual named executive officers, including salaries, bonuses, and equity grants, the Compensation Committee takes many factors into account, including such executive’s experience, responsibilities, management abilities, job performance, performance of the Company as a whole, current market conditions, an assessment of competitive pay for similar positions at comparable companies and at companies in other industries that could recruit the Company’s executives, and pay relative to other executives at the Company. These factors are considered by the Compensation Committee without any specific formula or weighting. The Company does not set compensation at a specific percentile of market comparisons. However, the Compensation Committee may reference the market from time to time for executives at similar companies to assess the overall competitiveness and reasonableness of pay.

In order to assist the Compensation Committee in evaluating the pay of the Chief Executive Officer and also in evaluating the Chief Executive Officer’s recommendation for the pay of the other named executive officers, the Compensation Consultant provided a competitive compensation analysis in 2021 to inform 2022 compensation decisions which relied, in part, on an analysis of compensation at peer companies that are considered to be the most suitable comparisons to the Company. In developing this group of peer companies, we considered input from FW Cook, which conducted an evaluation considering industry categorizations, revenue sizes, and peer company overlap among potential peers. We also incorporated feedback from management and the Compensation Committee regarding labor markets and comparability of potential peers. The peer group established in 2021, which will be used to inform 2022 pay decisions, consisted of 14 companies in the Chemical and Metal & Mining industries with a median market cap of $5 billion. These peer companies consisted of:

• Albemarle Corporation

• Alcoa Corporation

• Ashland Global Holdings Inc.

• Axalta Coating Systems Ltd.

• Cabot Corporation

• CF Industries Holdings, Inc.

• Cleveland-Cliffs Inc.

31

• Commercial Metals Company

• Compass Minerals International, Inc.

• Quaker Chemical Corporation

• The Mosaic Company

• Reliance Steel & Aluminum Co.

• Steel Dynamics, Inc.

• Westlake Chemical Corporation

The Compensation Committee believes that our executive team has unique skills and experience that, in some cases, limit the direct comparability of market data due to the relatively few number of mining companies. From time to time, the Compensation Committee evaluates the companies that are in our peer group and for continued appropriateness.

Elements of Compensation

During 2021, MP Materials’ executive compensation and benefits for its named executive officers consisted of the components listed in the table below, which provides a brief description of the principal types of compensation, how performance is factored into each type of compensation, and the objectives served by each element. A description of each element is discussed in greater detail following the table.

Base Salaries

We intend for the base salaries of our named executive officers to provide a minimum level of compensation for highly qualified executives. The base salaries of our named executive officers are subject to occasional modification based on an evaluation of each executive’s contribution, experience, responsibilities, external market data as well as the relative pay among senior executives at the Company. Each factor is considered on a discretionary basis without formulas or weights. We consider relative pay between executives because our perspective is that some consistency in pay emphasizes teamwork across the senior leadership level. In 2021, Mr. Litinsky did not receive a salary for the first year that the Company was a public company.

The table below shows the salaries earned by each named executive officer during 2021, which did not change as compared to the 2020 base salary levels for the continuing named executive officers. Mr. Hoops’ base salary was established at the time he joined the Company, considering the competitive market as well as the compensation received by his predecessor.

Name (1)	Salary
James H. Litinsky	$	0
Ryan Corbett	$	300,000
Michael Rosenthal	$	250,000
Elliot D. Hoops	$	350,000

(1) Ms. Bangalore resigned as Chief Strategy Officer and General Counsel in May 2021. Prior to her resignation, Ms. Bangalore had a base salary of $350,000.

In connection with the negotiations of their employment agreements in November 2021, effective as of January 1, 2022, the Compensation Committee increased the base salaries of each of the then-serving named executive officers as follows:

Name	Salary
James H. Litinsky	$	600,000
Ryan Corbett	$	425,000
Michael Rosenthal	$	425,000
Elliot D. Hoops	$	400,000

In connection with the increases in the base salaries of the named executive officers, the Compensation Committee reviewed a report produced by the Compensation Consultant regarding the base salaries of companies in its peer group. The base salaries approve by the Compensation Committee are below the median base salaries paid to equivalent named executive officers in the peer group.

Annual Bonuses

We provide our senior leadership team with short-term incentive compensation through an annual cash bonus program. Annual bonus compensation holds executives accountable, rewards the executives based on actual business results and helps create a “pay for performance” culture. Our 2021 annual cash bonus program provided cash incentive award opportunities based a qualitative assessment of performance for 2021. Bonus payouts for 2021 were determined based on a qualitative assessment of performance with respect to: (i) Company performance goals relating to safety, production, and profitability; (ii) department goals focused on team building and execution; and (iii) individual performance.

33

Based on our 2021 performance, the Compensation Committee of the Board of Directors awarded annual incentive awards to Messrs. Corbett, Rosenthal and Hoops, with a portion of the award delivered as fully vested stock awards granted in early 2022. Mr. Litinsky did not receive a bonus for the first year that the Company was a public company in 2021.

Name (1)	Annual Incentive Cash Award ($)		Annual Incentive Fully Vested Stock Award ($) (2)		Total Annual Incentive Compensation ($)
James H. Litinsky	$	0	$	0	$	0
Ryan Corbett	$	500,000	$	234,150	$	734,150
Michael Rosenthal	$	250,000	$	280,980	$	530,980
Elliot D. Hoops	$	275,000	$	187,320	$	462,320

(1) Ms. Bangalore did not receive a bonus for 2021.

(2) For the equity portion of the bonus, each executive officer received immediately vested restricted stock units under the 2020 Stock Incentive Plan. The restricted stock units were granted on January 14, 2022. In accordance with SEC disclosure rules, the fully vested stock awards granted in early 2022 based on 2021 performance will be reflected as 2022 compensation in the 2022 Summary Compensation Table and have been excluded from the 2021 Summary Compensation Table below.

Long-Term Incentives

We believe that awards of equity to our named executive officers provide a valuable incentive for them and helps align their interests with that of our stockholders for periods of time longer than one fiscal year. As part of our long-term incentive plan for 2021, we granted to our executive officers (other than Mr. Litinsky) restricted stock units. Restricted stock units also help align pay with performance as their value fluctuates with changes in the share price over time. However, restricted stock units also maintains some value in difficult economic environments and, therefore, meet our objectives of retaining executive talent and maintaining effective incentives during difficult economic environments. Given that 2021 was our first full year as a public company, it was a transition year. As we go forward, we will look to implement different types of equity awards which have performance metrics and timed-based vesting after considering input from our Compensation Consultant, market data and our executive compensation program objectives.

In connection with the negotiation of his employment agreement, we granted on November 18, 2021, to Mr. Litinsky 800,000 restricted stock units that vest over in four equal annual installments beginning on the first anniversary of the date of grant. In determining the number of restricted stock units to be granted to Mr. Litinsky, the Compensation Committee took into account the financial performance of the Company since the Business Combination, the various accomplishments that the Company had made in 2021, the Company’s stock performance, the fact that Mr. Litinsky had not received any compensation since the Business Combination and the size of an equity award that the Company would need to grant to a new Chief Executive Officer of the Company.

In March 2021, the Compensation Committee granted to Messrs. Corbett and Rosenthal and Ms. Bangalore the following grants of restricted stock units.

Name	Number of Restricted Stock Units with Time Based Vesting (2)		Dollar Amount of Restricted Stock Units with Time Based Vesting		Number of Restricted Stock Units with Immediate Vesting (3)		Dollar Amount of Restricted Stock Units with Immediate Vesting
Ryan Corbett		1,154	$	50,245		1,154	$	53,061
Michael Rosenthal		2,794	$	121,651		2,794	$	128,468
Sheila Bangalore (1)		524	$	22,815		524	$	24,094

(1) In connection with Ms. Bangalore’s Transition and Resignation Agreement, these restricted stock units were cancelled.

34

(2) These restricted stock units vest in four annual installments beginning on the first anniversary of the date of grant on March 16, 2022.

(3) These restricted stock units were granted as a part of the 2020 bonus and vested immediately on the date of grant on March 15, 2021.

In connection with Mr. Hoops’ appointment as General Counsel and Secretary and pursuant to the terms of his employment agreement, we granted the following equity awards: (1) on May 17, 2021, Mr. Hoops received a grant of $1 million in restricted stock units (36,429 restricted stock units) that vest in four equal annual installments beginning on May 17, 2022; and (2) on May 17, 2021, Mr. Hoops received a grant of $250,000 in immediately vested restricted stock units (9,107 restricted stock units).

Stock Ownership Guidelines

The Board of Directors has adopted stock ownership guidelines for its executive officers. Pursuant to its stock ownership guidelines, the Company’s executive officers are required to own the following shares of MP Common Stock by the end of the fifth year that the person was appointed to his or her position.

Name	Stock Ownership Guidelines
Chief Executive Officer		5 times annual base salary
Other Covered Executives		2 times annual base salary

The following interests count toward the targeted ownership: (1) shares of common stock owned outright; (2) shares held in trust for the benefit of the executive officer and director or such person’s family; (3) shares obtained through stock option exercise and the net in-the-money, after-tax value of vested but unexercised stock options; (4) shares of unvested time-based restricted stock; and (5) unvested time-based restricted stock units. As of the date of this Proxy Statement, each of the named executive officers exceeded the targeted ownership pursuant to the stock ownership guidelines.

Agreements with Named Executive Officers

In November 2021, the Company entered into new employment agreements, effective as of January 1, 2022, with Messrs. Litinsky, Corbett, Rosenthal and Hoops. In addition, the Company entered into a transition and resignation agreement with Ms. Bangalore in May 2021. For further details regarding these agreements, please see pages 45 and 46 of this Proxy Statement.

Hedging, Margin Accounts and Pledging MP Materials Common Stock

The Company’s insider trading plan prohibits executive officers and directors from hedging their ownership of MP Common Stock, including transactions in puts, calls, or other derivative instruments related to MP Common Stock. In addition, the Company’s insider trading plan prohibits executive officers and directors from placing shares of MP Common Stock in margin accounts and pledging shares of MP Common Stock.

Risk Assessments

With respect to risk related to compensation matters, the Compensation Committee considers, in establishing and reviewing the Company’s executive compensation program, whether the program encourages unnecessary or excessive risk taking and has concluded that it does not. Executives’ base salaries are fixed in amount and thus do not encourage risk-taking. Bonuses are capped and are tied to overall corporate performance.

A portion of compensation provided to the executive officers is in the form of restricted stock units that are important to help further align executives’ interests with those of the Company’s stockholders. The Compensation Committee believes that these awards do not encourage unnecessary or excessive risk-taking, as the value of these equity awards fluctuate dollar for dollar with the Company’s stock price and do not represent significant downward/upward risk and reward.

35

Recovery of Incentive Compensation Policy

The Board has adopted a policy on recovery of incentive compensation in the event of a financial restatement, also known as a “clawback policy.” The policy provides that the Compensation Committee may take any action to recover all or a portion of any excess incentive compensation paid to an executive officer provided that (1) there is a restatement of the Company’s financial statements for the fiscal year for which a bonus was paid, other than a restatement due to changes in accounting rules or policy or applicable law, and (2) the Compensation Committee determines that the executive officer has received an excess incentive compensation for the relevant fiscal year. For purposes of the policy, “incentive compensation” means annual performance bonuses and long-term incentive awards (in each case, including cash, stock options, stock appreciation rights, restricted stock, restricted stock units, performance share units or other equity-based awards) paid, granted, vested, settled, or accrued.

Retirement and Welfare Benefits

The named executive officers are eligible to participate in all of the Company’s normal retirement and welfare programs on the same terms as generally available to substantially all of our full-time employees. These include a 401(k) plan and matching contributions, health and disability insurance coverage, and group life insurance programs. In addition, the Company’s named executive officers are covered by the Company’s general health plan applicable to all of the Company’s employees.

(1) In addition to the Cash Severance Benefit set forth in the table, each executive may be entitled to received certain accrued obligations as of the termination date, as described the “Employment Agreements” section below, which generally includes all accrued but unpaid base salary through the date of termination, a payment of any unpaid or unreimbursed business expenses, and any benefits provided under Company benefit plans.

(2) The basis for the Cash Severance Benefit upon a termination is the base salary for 2021 as of December 31, 2021, plus the target cash bonus opportunity for 2021, noting that the annual bonuses for the 2020 calendar year were all paid prior to December 31, 2021.

(3) Restricted stock and restricted stock unit award values were computed based on the closing price of the Company’s common stock on December 31, 2021 ($45.42 per share), which was the last trading day of 2021. Restrictions on unvested restricted stock units automatically lapse upon death, disability, or a change of control under the terms of the applicable award agreements or pursuant to a discretionary Board action as permitted under the terms of the 2020 Stock Incentive Plan (other than with respect to Mr. Hoops’ award in the event of his death or disability). The numbers in the table reflect an assumption that the Board took the discretionary action to accelerate vesting pursuant to the terms of the 2020 Equity Incentive Plan in the event of a change of control.

(4) In the event that executive is subject to excise taxes imposed under Code Section 4999 pursuant to Code Section 280G, payments and benefits received by the executive in relation to a change in control may be subject to reduction pursuant to the terms of the executive’s employment agreement. The amounts reflected in this table do not reflect the application of any reduction pursuant to the terms of the executive’s employment agreement.

Employment Agreements

The Company has entered into employment, with all of its key executive officers, including Messrs. Litinsky, Corbett, Rosenthal and Hoops. None of these agreements contain a single trigger in the event of change in control. The Company determined to enter into these employment agreements in recognition of the continuing need to attract and retain experienced, proven executives (particularly in light of the increased competition for talent in its industry) and to protect the Company from certain competitive risk.

The discussion below provides a summary of the key terms of the employment agreements that were in effect on December 31, 2021, and a summary of the key terms of the employment agreements that went into effect beginning on January 1, 2022. Finally, a summary of the transition and separation agreement relating to Ms. Bangalore’s resignation as Chief Strategy Officer and General Counsel, see “Bangalore Transition and Resignation Agreement” below.

Summary of Key Terms of Employment Agreements effective as of December 31, 2021

James H. Litinsky

Mr. Litinsky’s employment agreement became effective on November 17, 2020, and, pursuant to such agreement, Mr. Litinsky became the Company’s Chairman of the Board and Chief Executive Officer on November 17, 2020, the consummation date of the Business Combination.

42

Under the terms of Mr. Litinsky’s employment agreement, Mr. Litinsky did not receive a base salary for the first year that the Company was a public company in 2021. In addition, Mr. Litinsky did not receive a bonus in 2021. At any time on or after the one-year anniversary of the closing of the Business Combination, Mr. Litinsky had the ability to request that the Compensation Committee, in consultation with the Company’s Compensation Consultant, prepare and present a proposal to Mr. Litinsky of a compensation package (including base salary, annual cash and equity incentives and severance) that is competitive for a publicly-traded company of comparable size and consistent with the Company’s then-current pay strategy for senior executives, with the parties to negotiate in good faith a compensation package for Mr. Litinsky.

In the event Mr. Litinsky’s employment was terminated by the Company without “cause” or by Mr. Litinsky due to “good reason,” Mr. Litinsky would have been entitled to (i) (A) all accrued but unpaid base salary through the date of termination of his employment, (B) any unpaid or unreimbursed expenses, and (C) any benefits provided under the Company’s employee benefit plans upon a termination of employment, including rights with respect to equity participation under any applicable equity incentive plan of the Company or any award agreement or other related document with respect to the grant of any award under such equity incentive plan (the “Litinsky Accrued Obligations”) and (ii) a $2,000,000 severance payment, payable in installments over the one-year period following such termination. The severance payment was subject to Mr. Litinsky’s execution and non-revocation of a general release of claims in favor of the Company and subject to Mr. Litinsky’s continued compliance with the customary restrictive covenants, including covenants relating to non-competition and non-solicitation for a period of one year following termination, contained in the employment agreement. In the event Mr. Litinsky’s employment was terminated due to his death or disability or in the event that a change in control occurs, (i) Mr. Litinsky would have been entitled to receive only the Litinsky Accrued Obligations and (ii) Mr. Litinsky’s unvested restricted stock units automatically would have vested. In the event Mr. Litinsky’s employment was terminated by the Company for cause or by Mr. Litinsky without good reason, Mr. Litinsky would have been entitled to receive only the Litinsky Accrued Obligations.

Ryan Corbett

Effective as of July 13, 2020, Mr. Corbett entered into an employment agreement, which provided that he would continue to serve as the Company’s Chief Financial Officer after the consummation of the Business Combination on November 17, 2020. Mr. Corbett’s employment agreement provided the following: (i) an initial base salary of $300,000; (ii) participation in the Company’s annual cash incentive program, with an annual incentive target of not less than $300,000 and payouts determined based on performance; and (iii) participation in the Company’s annual equity incentive program.

In the event Mr. Corbett’s employment was terminated due to his death or disability, Mr. Corbett would have been entitled to the following: (i) all accrued but unpaid base salary through the date of such termination; (ii) a payment of any unpaid or unreimbursed business expenses; (iii) any benefits provided under a Company benefit plan ((i), (ii) and (iii) are referred to collectively as the “Corbett Accrued Obligations”); (iv) the unpaid portion of any annual bonus earned with respect to the prior calendar year; (v) a bonus for the year of termination, based on the target annual bonus for the calendar year of termination, pro-rated based on days served during such calendar year; and (vi) Mr. Corbett’s unvested restricted stock and restricted stock units automatically would vest. In the event Mr. Corbett’s employment was terminated by the Company without “cause” or by Mr. Corbett due to “good reason,” Mr. Corbett would have received (i) the Corbett Accrued Obligations; (ii) the unpaid portion of any bonus earned with respect to the prior calendar year; (iii) a bonus for the year of termination, based on actual performance for the calendar year and pro-rated based on days served during the calendar year; (iv) severance in the form of the continuation of his then-current base salary for twelve-months post-termination; and (v) Mr. Corbett’s unvested restricted stock automatically would vest. The severance benefits were subject to Mr. Corbett’s execution and non-revocation of a general release of claims in favor of the Company and subject to Mr. Corbett’s continued compliance with the customary restrictive covenants, including covenants relating to non-competition and non-solicitation for a period of one year following termination, contained in the employment agreement. If a change in control had occurred, Mr. Corbett’s unvested restricted stock automatically would have vested based on the award terms and the Board had the discretionary authority to accelerate

43

the vesting of his restricted stock units. In the event that Mr. Corbett’s employment was terminated with cause or terminated by Mr. Corbett without good reason, Mr. Corbett would have been entitled to receive only the Corbett Accrued Obligations.

Michael Rosenthal

Effective as of July 1, 2020, Mr. Rosenthal entered into an employment agreement, which provided that he would continue to serve as CEO of the Company until the closing of the Business Combination, at which time he assumed the role of Chief Operating Officer. Under the employment agreement, Mr. Rosenthal received an annual base salary of not less than $250,000 and was eligible to participate in the Company’s annual incentive program.

In the event Mr. Rosenthal’s employment was terminated due to his death or disability, Mr. Rosenthal’s unvested restricted stock and restricted stock units automatically would vest. In the event Mr. Rosenthal’s employment was terminated by the Company without “cause” or by Mr. Rosenthal due to “good reason,” (i) Mr. Rosenthal would have been entitled to severance payments equal to six-months of his then-current base salary, payable in installments over the six-month period following such termination and (ii) Mr. Rosenthal’s unvested restricted stock automatically would have vested. The severance payment was subject to Mr. Rosenthal’s execution and non-revocation of a general release of claims in favor of the Company and subject to Mr. Rosenthal’s continued compliance with the customary restrictive covenants, including covenants relating to non-competition and non-solicitation for a period of one year following termination, contained in the employment agreement. If a change in control had occurred, Mr. Rosenthal’s unvested restricted stock and restricted stock units automatically would have vested.

Elliot D. Hoops

On April 14, 2021, we entered into an employment agreement with Mr. Hoops to become the General Counsel and Secretary of the Company effective as of May 17, 2021. Mr. Hoops’ employment agreement provided the following: (i) an initial base salary of $350,000; (ii) participation in the Company’s annual cash incentive program, with an annual incentive target of not less than $350,000 and payouts determined based on performance; and (iii) participation in the Company’s annual equity incentive program.

44

employment agreement. If a change in control had occurred, Mr. Hoops’ unvested restricted stock units were subject to accelerated vesting in the discretion of the Board. In the event that Mr. Hoops’ employment was terminated with cause or terminated by Mr. Hoops without good reason, Mr. Hoops would only have been entitled to receive the Hoops Accrued Obligations.

Summary of Key Terms of New Employment Agreements effective January 1, 2022

On November 18, 2021, the Company entered into new employment agreements, effective as of January 1, 2022, with each of Messrs.

In some circumstances, a portion of the Executives’ annual bonuses may be paid in restricted stock, restricted stock units or other equity awards.

If an Executive’s employment terminates, the Executive would receive all accrued but unpaid base salary and, except in the case of dismissal for “cause” (as defined in the Employment Agreements), an annual bonus for the year of termination based on the actual financial results for the full year in which the termination occurred, prorated for the portion of the year before termination of the Executive’s employment.

If an Executive’s employment is terminated by the Company without cause or by the Executive for “good reason” (as defined in the Employment Agreements) other than prior to, on or within 24 months following a “change of control” (as defined in the Employment Agreements), Mr. Litinsky would be entitled to 1.5 times the sum of his annual base salary and target bonus and Messrs.

The Executive would also be entitled to receive continuation of health benefits coverage for the Executive and the Executive’s dependents and disability insurance coverage for the Executive for up to 18 months following termination. In addition, all of Mr. Litinsky’s outstanding equity awards that do not contain performance-based vesting conditions (“Time Vested Awards”) shall immediately become vested as of the date of termination. With respect to Messrs. Corbett, Rosenthal and Hoops, all of their Time Vested Awards that vest over the period of time following termination until the end of the following calendar year following termination shall vest in full as of the date of termination. Further, Mr. Corbett’s grant of 150,000 shares of restricted stock on November 17, 2020, and Mr. Rosenthal’s grant of 1,563,006 shares of restricted stock on November 17, 2020, shall vest in full as of the date of such termination.

If an Executive’s employment is terminated by the Company without cause or by the Executive for “good reason” within ninety (90) days prior to, on or within twenty-four (24) months after a “change of control” (as such terms are defined in the Employment Agreements), the Executive would be entitled to a lump sum payment of 2 times the sum of his annual base salary and target bonus.

45

Company’s expense, continuation of health benefits coverage for the Executive and the Executive’s dependents and disability insurance coverage for the Executive for up to 18 months following termination. In addition, all Time Vested Awards shall vest in full as of the date of termination.

All termination payments are expressly conditioned on the executive providing a written release of all liabilities to the Company and the executive’s agreement to comply with the restrictive covenants described below for the time period for which such payments are made.

Bangalore Transition and Resignation Agreement

In early April 2021, Ms. Bangalore and the Chief Executive Officer discussed Ms. Bangalore’s desire to seek new opportunities. On April 14, 2021, we entered into an employment agreement with Mr. Hoops who assumed the role of General Counsel and Corporate Secretary on May 17, 2021. On April 27, 2021, we entered into a transition and resignation agreement with Ms. Bangalore. Ms. Bangalore agreed to remain in our employment through May 31, 2021, or such earlier date as we specified (the “resignation date”), and thereafter to serve as a non-employee advisor to us through June 30, 2021, in order to assist in effecting a smooth transition. Pursuant to the terms of the transition and resignation agreement, 10,000 shares of time-based vesting restricted stock previously granted to Ms. Bangalore immediately vested on May 27, 2021 (value of $280,500 based on the closing stock price on May 27, 2021). All of Ms. Bangalore’s remaining unvested equity awards were automatically forfeited. Further, we paid Ms. Bangalore $50,000 in cash compensation in addition to base salary earned through the resignation date. The transition and resignation agreement contained customary release, confidentiality, non-competition and non-solicitation provisions.

PROPOSAL TWO

RATIFICATION OF THE APPOINTMENT OF KPMG LLP AS OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR THE FISCAL YEAR ENDING DECEMBER 31, 2022

Our Board and the Audit Committee are asking our stockholders to ratify the appointment by the Audit Committee of KPMG LLP (“KPMG”), as the independent public accounting firm to conduct the audit of our financial statements for the fiscal year ending December 31, 2022. Stockholder ratification of such appointment is not required by our Bylaws or any other applicable legal requirement. However, our Board is submitting the appointment of KPMG to our stockholders for ratification as a matter of good corporate governance.

In the event our stockholders fail to ratify the appointment, the Audit Committee will reconsider whether or not to continue to retain KPMG for the fiscal year ending December 31, 2022. Even if the appointment is ratified, the Audit Committee in its discretion may direct the appointment of a different independent registered public accounting firm at any time during the year if the Audit Committee believes that such a change should be made. Representatives of KPMG are expected to be present at the Annual Meeting. They will have an opportunity to make statements if they desire and will be available to respond to appropriate questions.

On November 17, 2020, the Audit Committee approved the engagement of KPMG as the Company’s independent registered public accounting firm to audit the Company’s consolidated financial statements for the year ended December 31, 2020. KPMG served as the independent registered public accounting firm of MP Mine Operations LLC (“MPMO”) prior to the Business Combination (as defined below). WithumSmith+Brown, PC (“Withum”), the Company’s independent registered public accounting firm prior to November 17, 2020, was informed that it would be replaced by KPMG as the Company’s independent registered public accounting firm following completion of the Business Combination.

On November 17, 2020, the Company consummated the transactions contemplated by the Agreement and Plan of Merger, dated as of July 15, 2020, as amended on August 26, 2020 (the “Merger Agreement”), by and among Fortress Value Acquisition Corporation (“FVAC”), certain direct wholly-owned subsidiaries of FVAC, MPMO, which owns the Mountain Pass mine and processing facilities, and Secure Natural Resources LLC, a Delaware limited liability company (“SNR”), which holds the mineral rights to the Mountain Pass mine and surrounding areas as well as intellectual property rights related to the processing and development of rare earth minerals. Pursuant to the Merger Agreement, among other things, MPMO and SNR each became wholly-owned subsidiaries of FVAC (the “Business Combination”), which was in turn renamed “MP Materials Corp.”

Withum’s report on our balance sheet as of June 30, 2020, and the related statements of operations, changes in stockholders’ equity and cash flows, for the period from January 24, 2020, through June 30, 2020, did not contain any adverse opinion or disclaimer of opinion, nor were they qualified or modified as to uncertainty, audit scope or accounting principles. During the period from January 24, 2020, through June 30, 2020, and the subsequent period through November 17, 2020, there were no: (i) disagreements with Withum on any matter of accounting principles or practices, financial statement disclosures or audited scope or procedures, which disagreements if not resolved to Withum’s satisfaction would have caused Withum to make reference to the subject matter of the disagreement in connection with its report or (ii) reportable events as defined in Item 304(a)(1)(v) of Regulation S-K.

During the period from January 24, 2020, through June 30, 2020, and the interim period through November 17, 2020, the Company did not consult KPMG with respect to either (i) the application of accounting principles to a specified transaction, either completed or proposed; or the type of audit opinion that might be rendered on the Company’s financial statements, and no written report or oral advice was provided to the Company by KPMG that KPMG concluded was an important factor considered by the Company in reaching a decision as to the accounting, auditing or financial reporting issue; or (ii) any matter that was either the subject of a disagreement,

47

as that term is described in Item 304(a)(1)(iv) of Regulation S-K under the Exchange Act and the related instructions to Item 304 of Regulation S-K under the Exchange Act, or a reportable event, as that term is defined in Item 304(a)(1)(v) of Regulation S-K under the Exchange Act.

The Company has provided Withum with a copy of the foregoing disclosures and has requested that Withum furnish the Company with a letter addressed to the SEC stating whether it agrees with the statements made by the Company set forth above. A copy of Withum’s letter, dated November 23, 2020, is filed as Exhibit 16.1 to the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2021, which is incorporated by reference to Exhibit 16.1 to the Company’s Current Report on Form 8-K filed on November 23, 2020.

Principal Accountant Fees and Services

We were billed by KPMG and Withum in the years ended December 31, 2021, and 2020 as follows:

	Years Ended December 31,
	2021		2020
Audit fees	$	1,988,000	$	612,570
Audit-related fees		—		—
Tax fees		—		—
All other fees		—		—
Total fees	$	1,988,000	$	612,570

There were no Audit-related fees, Tax fees or All other fees billed by KPMG during the year ended December 31, 2021.

Determination of Independence

In considering the nature of the services provided by our independent registered public accounting firm, the Audit Committee determined that such services are compatible with the provision of independent audit services. The Audit Committee discussed these services with our independent registered public accounting firm and our management to determine that they are permitted under the rules and regulations concerning auditor independence.

Additional information concerning the Audit Committee and its activities can be found in the following sections of this Proxy Statement: “Corporate Governance— Board Committees—Audit Committee” and “Report of the Audit Committee.”

Pre-Approval Policy

According to policies adopted by the Audit Committee and ratified by our Board, to ensure compliance with the SEC’s rules regarding auditor independence, all audit and non-audit services to be provided by our independent

48

registered public accounting firm must be pre-approved by the Audit Committee. The Audit Committee has established a general pre-approval policy for certain audit and non-audit services, up to a specified amount for each identified service that may be provided by the independent auditors.

The Audit Committee approved one hundred percent (100%) of all services provided by KPMG during the years ended December 31, 2021. The Audit Committee has considered the nature and amount of the fees billed by KPMG and believes that the provision of the services for activities unrelated to the audit is compatible with maintaining KPMG’s independence.

Recommendation of Our Board of Directors and Audit Committee

OUR BOARD OF DIRECTORS AND OUR AUDIT COMMITTEE UNANIMOUSLY RECOMMEND THAT OUR STOCKHOLDERS VOTE “FOR” THE RATIFICATION OF THE APPOINTMENT OF KPMG LLP AS OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR THE FISCAL YEAR ENDING DECEMBER 31, 2022.

49

REPORT OF THE AUDIT COMMITTEE

Management is responsible for the preparation, presentation and integrity of the Company’s financial statements, accounting and financial reporting principles, internal controls and procedures designed to ensure compliance with accounting standards, applicable laws and regulations. The Audit Committee is responsible for appointing, compensating, overseeing and, where appropriate, discharging and replacing the Company’s independent registered public accounting firm (the “independent accounting firm”). In addition, the Audit Committee is involved in the selection of the lead audit engagement partner whenever a rotational change is required by applicable law or listing standards or for any other reason. The independent accounting firm is responsible for expressing an opinion on the conformity of the Company’s audited financial statements with generally accepted accounting principles. In addition, the independent accounting firm will express its own opinion on the effectiveness of the Company’s internal controls over financial reporting. The Audit Committee is responsible for monitoring and overseeing these processes.

The function of the Audit Committee is not intended to duplicate or attest as to the activities of management and the independent accounting firm, nor can the Audit Committee certify that the independent accounting firm is “independent” under applicable rules. The Audit Committee serves a board level oversight role, in which it provides advice, counsel and direction to management and the independent accounting firm on the basis of the information it receives, discussions with management and the independent accounting firm and the experience of the Audit Committee’s members in business, financial and accounting matters.

In this context, the Audit Committee met and held numerous discussions with management and the independent accounting firm during 2021. Management represented to the Audit Committee that the Company’s consolidated financial statements were prepared in accordance with GAAP, and the Audit Committee has reviewed and discussed the consolidated financial statements with management and the independent accounting firm. The Audit Committee discussed with the independent accounting firm matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board. The independent accounting firm also provided to the Audit Committee the written disclosures and the letter required by Rule 3526 of the Public Company Accounting Oversight Board, Communications with Audit Committees Concerning Independence, and the Audit Committee discussed with the independent accounting firm the firm’s independence.

Based upon the Audit Committee’s discussion with management and the independent accounting firm and the Audit Committee’s review of the representations of management and the report of the independent accounting firm on the Consolidated Financial Statements, the Audit Committee recommended that the Board of Directors include the audited consolidated financial statements in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2021 filed with the SEC on February 28, 2022.

PROPOSAL THREE

ADVISORY VOTE TO APPROVE COMPENSATION PAID TO

THE COMPANY’S NAMED EXECUTIVE OFFICERS

We are pleased to provide our stockholders with the opportunity to approve, on an advisory basis, determinations made by the Compensation Committee and the Board of Directors regarding the compensation of our named executive officers for 2021, pursuant to Section 14 of the Exchange Act, as described in the Compensation Discussion and Analysis section, and the subsequent tabular and narrative disclosure beginning on page 28 of this Proxy Statement (the “CD&A”).

We believe stockholders should approve of the Company’s 2021 compensation program because it is performance based and it is appropriate in the context of industry standards and aligns executive compensation with stockholder interests. As more specifically described in the CD&A, the Committee believes the compensation paid to Mr. Litinsky, the Company’s Chief Executive Officer in 2021, is reasonable and appropriate in light of the Company’s scale, objectives, achievements and performance.

We urge you to carefully review the CD&A so that you have a complete understanding of how important our compensation program is to the continued success of the Company. You will find in the CD&A a detailed discussion of the Company’s pay-for-performance compensation philosophy, the elements of our compensation program and the specific payments made to named executive officers with respect to 2021. The Company’s compensation program is fundamental to the approach we employ to attract, motivate and, most importantly, retain our named executive officers. To that end, we believe we have designed a compensation program that is strongly grounded on pay-for-performance principles, and which features a significant amount of “at risk” compensation, as described in more detail in the CD&A. We believe this strategy continues to achieve its intended outcome. The Company’s recent performance, inclusive of 2021, has been strong, which we believe is based in large part on the focused and strategic leadership of the Company’s management team.

We believe that the Company’s 2021 achievements, as described in “Overview of MP Materials Corp.”, coupled with the Company’s record of providing long-term value creation amply supports the compensation paid to the named executive officers. As an advisory vote, the results of this vote will not be binding on the Board or the Company. However, we urge you to endorse our pay-for-performance compensation program, particularly in light of the Company’s strong performance and significant achievements over both the short-term and long-term.

As discussed in Proposal Four, we expect to hold future say-on-pay proposals in our proxy materials on an annual basis, and we expect that the next advisory vote to approve the compensation of our named executive officers will take place at the 2023 annual meeting of stockholders.

The Board of Directors unanimously recommends that stockholders cast their non-binding advisory vote “FOR” the following resolution:

“RESOLVED, that the stockholders of the Company approve, on an advisory basis, the compensation of the Company’s named executive officers, as disclosed pursuant to Item 402 of Regulation S-K, including the Compensation Discussion and Analysis, the compensation tables and the accompanying narrative disclosure included in the Company’s proxy statement for the 2022 Annual Meeting of Stockholders.”

PROPOSAL FOUR

ADVISORY VOTE ON THE FREQUENCY OF FUTURE ADVISORY VOTES ON COMPENSATION OF THE COMPANY’S NAMED EXECUTIVE OFFICERS

Pursuant to Section 14A of the Exchange Act, we are asking stockholders to vote on whether future advisory votes on executive compensation should occur every year, every two years or every three years.

After careful consideration, the Board of Directors has determined that holding an advisory vote on executive compensation every year is the most appropriate policy for the Company at this time and recommends that stockholders vote for future advisory votes on executive compensation to occur every year. The Board of Directors believes that holding an annual advisory vote on executive compensation provides the Company with more direct and immediate feedback on our compensation disclosures. We believe that an annual advisory vote on executive compensation is consistent with our practice of seeking input and engaging in dialogue with our stockholders on corporate governance matters and our executive compensation philosophy, policies and practices.

This advisory vote on the frequency of future advisory votes on executive compensation is non-binding on the Board of Directors. Stockholders will be able to specify one of four choices for this proposal on the proxy card: one year, two years, three years or abstain. Stockholders are not voting to approve or disapprove the Board’s recommendation. Although non-binding, the Board of Directors and the Compensation Committee will carefully review the voting results in their entirety. Notwithstanding the Board’s recommendation and the outcome of the advisory stockholder vote on executive compensation for 2021, the Board may in the future decide to conduct advisory votes on executive compensation on a more or less frequent basis and may vary its practice based on factors such as discussions with stockholders and the adoption of material changes to compensation program.

THE BOARD OF DIRECTORS RECOMMENDS THAT STOCKHOLDERS VOTE TO CONDUCT FUTURE ADVISORY VOTES ON EXECUTIVE COMPENSATION EVERY YEAR.
