All references herein to periods prior to January 4, 2024 refer to Livent, the Company’s predecessor. The term shareholder in relation to the Company means a member of the Company (as used in the Company's Articles of Association).

INFORMATION ABOUT VOTING

Who Can Vote

You can vote at the Annual Meeting if you were a holder of the Company’s ordinary shares, par value of $1.00 per share (“Ordinary Shares”) or CDIs (as defined below), on the record date. The record date is the close of business on May 31, 2024. You will have one vote for each share of Ordinary Shares. As of the record date, there were 1,075,210,958 Ordinary Shares outstanding.

How to Vote

You may vote in one of four ways:

You can vote by signing and returning the enclosed proxy card if you have elected to receive a full set of proxy materials. This will authorize and instruct the individuals named on the card to vote your shares at the Annual Meeting in the way you indicate;

You can vote by internet prior to the Annual Meeting;

You can vote by telephone prior to the Annual Meeting; or

You can cast your vote by internet at the Annual Meeting.

If you hold CDIs, you must obtain a valid CDI Voting Instruction Form (as defined below) from CDN (as defined below) in order to vote. Please see “Holders of Chess Depositary Interests – Special Voting Instructions” below for further instructions.

Use of Proxies

We plan to vote signed and returned proxies without specific instructions FOR the Board nominees for director, FOR Proposals 2 and 3, and a vote FOR “one year” as the preferred frequency of future advisory votes to approve named executive officer compensation, and in the discretion of the proxy holders as to any other matters that may properly come before the Annual Meeting.

Quorum Requirement

We need a quorum of shareholders to hold a valid Annual Meeting. A quorum will be present if the holders of at least a majority of the outstanding Ordinary Shares entitled to vote at the meeting either attend the Annual Meeting virtually or are represented by proxy at the Annual Meeting. Abstentions and broker non-votes (described below) are counted as present for the purpose of establishing a quorum. Shareholders who attend the Annual Meeting by following the instructions above under “How to Vote” will be considered to be attending the meeting “in person.”

Vote Required For Action

Directors are elected by a majority of the votes cast in an uncontested election. Because the number of nominees properly nominated for the Annual Meeting is the same as the number of directors to be elected at the Annual Meeting, the election of directors is an uncontested election. As a result, any nominee who receives a majority of the votes cast with respect to his or her election at the Annual Meeting will be elected to the Board (or re-elected, in the case of any nominee who is an incumbent director). Under our Articles of Association, if an incumbent nominee fails to receive the required number of votes for re-election, within ninety (90) days after certification of the election results, the Nominating and Corporate Governance Committee of the Board will recommend to the Board whether to accept or reject the resignation or whether other action should be taken and the Board will act on the Nominating and Corporate Governance Committee’s recommendation. Under our Articles of Association, incumbent

Arcadium Lithium plc 2 2024 Proxy Statement

TABLE OF CONTENTS

nominees have tendered a contingent resignation which would become effective if (i) the nominee does not receive a majority of the votes cast with respect to his or her election at the Annual Meeting and (ii) the Board accepts such resignation. Adoption of Proposals 2, 3 (which is non-binding) and 4 (which is non-binding) require the affirmative vote of the majority of votes cast at the meeting.

Abstentions or Lack of Instructions to Banks or Brokers

With respect to Proposals 1 through 4, abstentions will not be counted as votes cast, and thus will have no effect on the Proposals 1 through 4.

A broker non-vote occurs when a bank, broker or other nominee holding shares on behalf of a shareholder does not receive voting instructions from the beneficial owner with respect to a non-routine matter to be voted on at the Annual Meeting by a specified date before the Annual Meeting. Banks, brokers and other nominees may vote undirected shares on matters deemed routine in accordance with New York Stock Exchange (“NYSE”) rules, but they may not vote undirected shares on matters deemed non-routine in accordance with such rules. For this purpose, only the ratification of the appointment of the independent registered public accounting firm is considered a routine matter.

In the event of a broker non-vote in the election of directors, the non-binding advisory vote regarding named executive officer compensation or the non-binding advisory vote regarding the preferred frequency of future advisory votes to approve named executive officer compensation at the Annual Meeting, the broker non-vote will not have any effect on the outcome inasmuch as broker non-votes are not counted as votes cast or as shares present and entitled to be voted with respect to any matter on which the broker has expressly not voted.

Holders of Chess Depositary Interests – Special Voting Instructions

Arcadium would like to remind CDI holders of the particular requirements and restrictions that their votes will be subject to.

A CDI is a CHESS Depositary Interest (“CDI”) traded on the Australian Securities Exchange (“ASX”) and represents an uncertificated unit of beneficial ownership in the shares of the Company. CDI holders do not actually own direct legal title to shares, which is held for and on behalf of CDI holders by CHESS Depositary Nominees Pty Limited (“CDN”), a wholly owned subsidiary of ASX Limited. CDN is authorized by its Australian Financial Services Licence to operate custodial and depositary services, other than investor directed portfolio services, to wholesale and retail clients. This structure exists because the Company is listed on the NYSE with a right to have its securities traded on the ASX by way of CDIs.

CDN or its custodian is considered the holder of record for purposes of voting at our Annual Meeting. As the beneficial owner, you have the right to direct CDN on how to vote the shares in your account. As a beneficial owner, you are invited to attend the Annual Meeting. As CDIs are technically rights to Ordinary Shares held on behalf of CDI holders by CDN, CDI holders need to provide confirmation of their voting intentions to CDN before the Annual Meeting. CDN will then exercise the votes on behalf of CDI holders.

In order to have votes cast at the Annual Meeting on their behalf, CDI holders must complete, sign and return the enclosed CDI voting instruction form (the “CDI Voting Instruction Form”) to Computershare Investor Services Pty Limited (“Computershare”), the CDI registry in Australia, in accordance with the instructions below. You will have one (1) vote for one (1) CDI.

CDN is required to follow the voting instructions properly received from CDI holders. If a CDI holder holds its interest in CDIs through a broker, dealer or other intermediary, it will need to follow the instructions of its intermediary.

CDI Voting Instruction Forms may be lodged in one of the following ways:

	Online			Online at www.investorvote.com.au. To use the online lodgment facility, CDI holders will need their holder number (Securityholder Reference Number (SRN) or Holder Identification Number (HIN)) as shown on the front of the CDI Voting Instruction Form.
	By Post			Computershare Investor Services Pty Limited, GPO Box 242, Melbourne, Victoria 3001.
	By fax			1800 783 447 within Australia or +61 3 9473 255 outside Australia.

Arcadium Lithium plc 3 2024 Proxy Statement

TABLE OF CONTENTS

Completed CDI Voting Instruction Forms must be provided to Computershare no later than 12:00 a.m. AEST on Monday, July 22, 2024 (2:00 p.m. GMT on Sunday, July 21, 2024) or four (4) full business days before any adjourned or postponed Annual Meeting, in accordance with the instructions on that form. The CDI voting deadline is two (2) business days prior to the date that proxies are due, so that CDN has sufficient time to vote the Ordinary Shares underlying the applicable CDIs.

Revoking a Proxy

You may revoke your proxy at any time before it is exercised. You can revoke a proxy by:

•	Sending a written notice to the Corporate Secretary of Arcadium at Arcadium Lithium plc, 1818 Market Street, Suite 2550, Philadelphia, PA 19103;

•	Delivering a properly executed, later-dated proxy; or

•	Attending the Annual Meeting and voting by internet, provided that you comply with the conditions set forth in the section of this proxy statement above entitled “How to Vote.”

CDI holders that wish to change their vote must, no later than the due date for lodgment of CDI Voting Instruction Forms above, contact Computershare to arrange to change their vote.

II. The Proposals to be Voted on

PROPOSAL 1:

Election of Directors

NOMINEES FOR DIRECTOR

The Board consists of twelve directors. All directors serve for a term ending at the next annual general meeting of shareholders following their appointment or the annual general meeting of shareholders at which they were elected, as applicable, and until their successors are elected and qualified, or until their earlier death, resignation, disqualification or removal. Vacancies on the Board are filled by a majority of the directors then in office, even though fewer than a quorum, or by a sole remaining director. Any director elected to fill a vacancy will hold office until the next annual general meeting of shareholders following his or her appointment.

The Board currently consists of twelve directors: our President and Chief Executive Officer, Paul W. Graves, and eleven directors who are “independent” under the listing standards of the NYSE. The independent directors are Michael F. Barry, Peter Coleman, Alan Fitzpatrick, Florencia Heredia, Leanne Heywood, Christina Lampe-Önnerud, Pablo Marcet, Steven T. Merkt, Fernando Oris de Roa, Robert C. Pallash and John Turner. Under our Articles of Association, our directors will be elected annually by a majority of votes cast in uncontested elections. As discussed under “Information about the Board of Directors and Corporate Governance—Committees and Independence of Directors” below, our Nominating and Corporate Governance Committee is responsible for recommending to our Board, for its approval, the director nominees to be presented for shareholder approval at each annual meeting.

Each of the twelve director nominees (the “Director Nominees”) listed below is currently a director of the Company and has agreed to stand for election. If elected, each director’s next term will expire at the 2025 annual meeting of shareholders. Information about the nominees is contained in the section of this proxy statement entitled “Board of Directors.”

The Board expects that each of the Director Nominees will be able and willing to serve as directors. If any nominee becomes unavailable, the proxies may be voted for another person nominated by the Board to fill the vacancy, or the size of the Board may be reduced.

The Board of Directors recommends a vote FOR the election of Paul W. Graves, Michael F. Barry, Peter Coleman, Alan Fitzpatrick, Florencia Heredia, Leanne Heywood, Christina Lampe-Önnerud, Pablo Marcet, Steven T. Merkt, Fernando Oris De Roa, Robert C. Pallash and John Turner to the Board of Directors as described above.

TABLE OF CONTENTS

PROPOSAL 2:

Ratification of Appointment of Independent Registered Accounting Firm

The Audit Committee of the Board of Directors is directly responsible for the appointment, compensation, retention and oversight of the independent external audit firm retained to audit the Company’s financial statements. The Audit Committee has approved KPMG LLP (“KPMG”) continuing to serve as the Company’s independent registered public accounting firm for 2024.

The Audit Committee periodically reviews the performance of the independent external audit firm. In conjunction with the mandated rotation of KPMG’s lead engagement partner, the Audit Committee and its chairperson also evaluate and approve the selection of KPMG’s new lead engagement partner.

The Audit Committee is responsible for the audit fee negotiations associated with the Company’s retention of KPMG. For the fiscal years 2022 and 2023, KPMG’s fees, all of which were approved by the Audit Committee, are included in the table below.

(In Thousands)	2023	2022
Audit Fees⁽¹⁾	$5,835	$3,232
Audit Related Fees⁽²⁾	185	29
Tax Fees⁽³⁾	137	200
All Other Fees⁽⁴⁾	0	0
TOTAL	$6,157	$3,461

(1)

Fees for professional services performed by KPMG for the integrated audit of the Company’s annual consolidated financial statements included in the Company’s Form 10-K filing and quarterly reviews of the financial statements included in the Company’s Reports on Form 10-Q filings. The amount also includes other services that are normally provided by KPMG in connection with statutory and regulatory filings. The fiscal year 2023 fees also include registration statement review and integration procedures related to the merger of equals transaction between Livent and Allkem.

(2)	Fees for services performed by KPMG that include audit related services in connection with attestations by KPMG that are required by statute, regulation, or contractual requirements.

(3)	Fees for professional services performed by KPMG with respect to tax compliance reviews.

(4)	Fees for other permissible work performed by KPMG that do not fall within the categories set forth above.

PRE-APPROVAL OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM SERVICES

The Audit Committee has adopted a Pre-Approval Policy with respect to audit and non-audit services performed by its independent registered public accounting firm. The following is a summary of the Pre-Approval Policy.

Prior to the commencement of services for a given year, the Audit Committee grants pre-approval of expected services and estimated fees, as presented by the independent registered public accounting firm. The independent registered public accounting firm routinely updates the Audit Committee during the year in which the services are performed as to the actual services provided and related fees pursuant to the Pre-Approval Policy.

Unexpected services or services for which the fees to be incurred would exceed pre-approved amounts, require specific approval before the services may be rendered. Requests or applications to provide such services that require specific approval by the Audit Committee are submitted to the Chair of the Audit Committee by both the Company’s Chief Financial Officer and the independent registered public accounting firm.

Arcadium Lithium plc 6 2024 Proxy Statement

TABLE OF CONTENTS

The request or application includes a statement as to whether, in the view of both the independent registered public accounting firm and the Chief Financial Officer, such request or application is consistent with the rules of the Securities and Exchange Commission (“SEC”) regarding auditor independence. Authority to grant approval for such services is delegated to the Chair of the Audit Committee subject to a $100,000 limit for each request, and limited to $500,000 in the aggregate per year, provided that any such approval is then reviewed by the full Audit Committee at the next regularly scheduled meeting.

The Audit Committee has determined that the independence of KPMG has not been adversely impacted as a result of the non-audit services performed by such accounting firm.

We expect a representative of KPMG to attend the Annual Meeting. The representative will have an opportunity to make a statement if he or she desires and also will be available to respond to appropriate questions.

The Board of Directors recommends a vote FOR ratification of the appointment of KPMG LLP as the company’s independent registered public accounting firm for 2024.

Arcadium Lithium plc 7 2024 Proxy Statement

PROPOSAL 3:

Advisory (Non-Binding) Vote on Named Executive Officer Compensation

In accordance with the requirements of Section 14A of the Securities Exchange Act of 1934 (the “Exchange Act”) and the related rules of the SEC, our Board is submitting a proposal providing our shareholders the opportunity to cast a non-binding advisory vote on the executive compensation paid to the Company’s named executive officers (“named executive officers” or “NEOs”) as disclosed pursuant to Item 402 of Regulation S-K. As described under “Executive Compensation—Compensation Discussion and Analysis” below, in accordance with SEC rules, this proxy statement describes the philosophy, objectives, process, components and additional aspects of the 2023 executive compensation program of Livent, our predecessor SEC-registered issuer. Because the Livent-Allkem merger was completed after December 31, 2023, this proxy does not describe any of the compensation arrangements for the Company or the Company’s executive officers.

This advisory vote on named executive officer compensation is non-binding on the Board, will not overrule any decision by the Board and does not compel the Board to take any action. However, the Board and the Compensation Committee of the Board (the “Compensation Committee”) may consider the outcome of the vote when considering future executive compensation decisions. Specifically, to the extent there is any significant vote against the named executive officer compensation as disclosed in this proxy statement, the Board will consider our shareholders’ concerns and the Compensation Committee will evaluate whether any actions are necessary to address those concerns.

The Board and the Compensation Committee believe that Livent’s executive compensation programs and policies and the compensation decisions described in this proxy statement (i) supported Livent’s business objectives, (ii) linked the interests of the executive officers and shareholders, (iii) aligned NEO pay with individual and Livent’s performance, without encouraging excessive risk-taking that could have a material adverse effect on Livent, (iv) provided NEOs with a competitive level of compensation, and (v) promoted retention of the NEOs and other senior leaders.

Our shareholders are being asked to approve, on an advisory basis, the frequency with which we hold advisory votes to approve the compensation of our NEOs (see Proposal 4). As described in more detail in Proposal 4, the Board is recommending a vote for holding advisory votes to approve the compensation of our NEOs every year. Accordingly, the Board intends to hold the next advisory vote to approve our executive compensation program at the 2025 annual meeting of shareholders, unless the Board modifies its policy on the frequency of holding such advisory votes including in response to shareholders’ votes on Proposal 4.

For the reasons discussed above (and further amplified in the compensation disclosures made in this proxy statement), the Board recommends that shareholders vote in favor of the following resolution:

RESOLVED that the shareholders approve, on an advisory basis, the compensation of the Company’s named executive officers, as disclosed pursuant to the compensation disclosure rules of the Securities and Exchange Commission (which disclosure includes the Compensation Discussion and Analysis, the Summary Compensation Table and other related tabular and narrative disclosures set forth in this proxy statement).

The Board of Directors recommends a vote FOR the above resolution.

Arcadium Lithium plc 8 2024 Proxy Statement

TABLE OF CONTENTS

PROPOSAL 4:

Advisory (Non-Binding) Vote on the Frequency of Executive Compensation Voting (“Say-on-Pay Frequency Vote”)

In accordance with the requirements of the Exchange Act and the related rules of the SEC, our shareholders have the opportunity to indicate, on an advisory basis, how frequently we should seek an advisory vote on the compensation of our named executive officers, as disclosed pursuant to the SEC’s compensation disclosure rules. Shareholders may vote for a frequency of every one, two or three calendar years, or may abstain.

Our Board will take into consideration the outcome of this vote in making a determination about the frequency of future executive compensation advisory votes. However, because this vote is advisory and non-binding, our Board may decide that it is in the best interests of our shareholders and the Company to hold the advisory vote to approve executive compensation more or less frequently. In the future, we will propose an advisory vote on the frequency of the executive compensation advisory vote at least once every six calendar years.

After careful consideration, our Board believes that the executive compensation advisory vote should be held annually, and therefore our Board recommends that you vote for a frequency of “one year” for future executive compensation advisory votes. The Board believes that an annual executive compensation advisory vote will facilitate more direct shareholder input about executive compensation. An annual executive compensation advisory vote is consistent with our policy of reviewing our compensation program annually, as well as seeking frequent input from our shareholders on corporate governance and executive compensation matters.

The Board of Directors recommends a vote FOR one year as the preferred frequency of future shareholder advisory votes on the compensation of our named executive officers.

III. Board of Directors

DIRECTOR QUALIFICATIONS

Directors are selected based on integrity, successful business experience, stature in their own fields of endeavor and diversity of perspectives they bring to the Board. Desired attributes of all directors include (i) ability to reach thoughtful, independent and logical judgments on difficult and complex issues; (ii) demonstrated leadership; (iii) knowledge, experience and skills in areas relevant to the Company’s lines of business; (iv) objectivity; and (v) willingness and ability to cooperate and engage with other members of the Board openly and constructively. Directors must also be able to view the issues the Company faces from the shareholders’ perspective and be committed to representing the long-term interests of our shareholders. We also require that our directors be able to commit the time necessary to ensure the diligent performance of their duties. Our Corporate Governance Guidelines require that a majority of directors must be ‘independent’ within the meaning of the Sarbanes Oxley Act and NYSE listing standards.

Further, pursuant to our Corporate Governance Guidelines, it is the policy of the Board that the total number of public company boards on which an independent director may serve is limited to four, including the Board. In addition, the total number of public company boards on which a director who is the chief executive officer (“CEO”) or the named executive officer of a public company, including the CEO, may serve is limited to two, including the Board. A director must notify the Chair of the Nominating and Corporate Governance Committee prior to accepting any invitation to serve on another public company board or not-for-profit/tax-exempt board or with a government or advisory group that is expected to require significant commitments of time, in order for the Company to confirm the absence of any actual or potential conflict of interest.

BOARD REFRESHMENT AND DIVERSITY

A continuing priority of the Board is ensuring the Board is composed of directors who bring diverse perspectives and viewpoints and have a variety of skills, experiences and backgrounds to enable the Board to effectively fulfill its governance responsibilities and represent the long-term interests of its shareholders. The Nominating and Corporate Governance Committee and the Board regularly monitor the composition of the Board and evaluate the key qualifications, skills and attributes required in order to effectively refresh the Board with engaged and dynamic leaders with proven business track records who will bring fresh perspectives to the Board while maintaining the productive working dynamics and collegiality of the Board. The Nominating and Corporate Governance Committee and the Board are focused on identifying individuals whose characteristics will enable them to make meaningful contributions to the shaping of our business strategy. In addition, to support board refreshment and the maintenance of an appropriate balance of tenure, experience and perspectives, the Board maintains a mandatory retirement policy as described below in the section entitled “Retirement/Resignation Policy for Directors.”

As part of its consideration of director nominations and director succession, the Nominating and Corporate Governance Committee periodically reviews the appropriate skills and characteristics required of Board members such as integrity, successful business experience, stature in their own fields of endeavor, diversity of perspectives, recognized experience in Arcadium’s lines of business, and leadership in areas such as government service, academia, finance and international trade. We aim for a substantial representation of the independent Board members to be active or retired senior executives. A range in the age of Board members is also targeted to allow staggered retirement and replacement of desired skills on a planned basis with appropriate continuity. The Board is mindful that director tenure is an important consideration in evaluating Board composition. The average tenure of the director nominees is approximately six (6) months, not taking into consideration each director’s past service with Livent or Allkem, respectively. Each director was appointed to the Board on January 4, 2024 at the closing of the merger of equals transaction between Livent and Allkem forming the Company.

Additionally, due to the global and complex nature of our business, we believe that maintaining a diverse Board membership with varying backgrounds, skills, expertise and other differentiating personal characteristics enhances the quality and diversity of thought in the Board’s deliberations and enables the Board to better represent all of the Company’s constituents. In seeking candidates who possess diversity of experience, background and perspective, the Nominating and Corporate Governance

Arcadium Lithium plc 10 2024 Proxy Statement

TABLE OF CONTENTS

Committee casts a wide net and considers candidates from diverse backgrounds based on race, ethnicity, national origin, gender, industry experience, type of position held, and other corporate board experience. In addition to reviewing a candidate’s background and accomplishments, candidates are evaluated in the context of the current composition of the Board and the evolving needs of the Company.

The current Board composition is the result of the merger between Livent and Allkem, where six directors from each predecessor company are being represented on the Board. We believe that the current structure of the Board is important to the Company’s success as a newly-formed entity. As the Company transforms, we expect that the Board will also evolve, and in the coming years the Board will reflect the overall size, skills, qualification, background and experience, as well as diversity, that is supportive of our growth.

The Nominating and Corporate Governance Committee is actively engaged in evaluating its board composition, including director retirements that are expected to occur as a result of the Company’s governance policies in the next few years, and as needed, search for additional director candidates consistent with the Board’s focus on diversity. The Board is committed to increasing the percentage of women represented on the Board and believes that it will achieve a Board composition of at least 30% gender diverse directors within two years.

DIRECTOR COMPENSATION

Compensation Policy

Livent maintained the Livent Corporation Compensation Policy for Non-Employee Directors (“Director Compensation Policy”) to provide for the compensation of Livent’s non-employee directors, as described below. The Board of Directors of Livent (“Livent Board”) administered the Director Compensation Policy. The Director Compensation Policy was not applicable to directors who were also employees of Livent or its affiliates. Accordingly, Mr. Graves, Livent’s CEO, received no additional compensation for his service as a director. For a description of the compensation paid to Mr. Graves for his service during 2023 as Livent’s CEO, see the section titled “Executive Compensation”.

RETAINER AND FEES

Each Livent non-employee director was paid an annual retainer of $75,000 or a pro rata amount for any portion of a year served. The retainer was paid in four installments in cash unless the director elected to receive it in restricted stock units (“RSUs”). Restricted stock units granted in lieu of an annual cash retainer were awarded on May 1 of the relevant calendar year, and were subject to forfeiture on a pro rata basis if the director did not serve for the full year in respect of which the retainer was paid. The forfeiture condition was waived in the event of a change in control of the Company or if the director’s service ceased due to his or her death or disability.

Competitive market data on director pay levels and design practices were prepared by and reviewed with Livent’s compensation consultant, Aon plc (“Aon”). In February 2023, the Livent Nominating and Corporate Governance Committee recommended, and the Livent Board approved, changes to director compensation for the director compensation year beginning on May 1, 2023. Specifically, the fee paid to the chairs of the Livent Nominating and Corporate Governance Committee and the Livent Sustainability Committee increased to $12,000 (from $10,000), and the non-executive chair fee increased to $65,000 (from $20,000). Members of Livent’s committees received annual retainers with respect to their committee membership as follows: $7,500 for the Livent Audit Committee ($20,000 for the chair), $5,000 for the Livent Compensation Committee ($15,000 for the chair), and $4,000 for the Livent Nominating and Corporate Governance Committee and Livent Sustainability Committee. The chair of the Executive Committee did not receive any additional compensation with respect to such service. All such annual retainer, committee and chair payments are paid in four installments.

ANNUAL GRANT OF RESTRICTED STOCK UNITS

Each Livent non-employee director also received an annual grant of restricted stock units on May 1 of each calendar year having a value of $105,000 on the date of grant. These annual grants vested at the annual meeting of Livent stockholders held in the year following the date of grant or, if sooner, upon a change in control of Livent. In addition, the RSUs would vest on a pro rata basis if the director died before the annual meeting at which the units would have otherwise vested. Upon the completion of the merger on January 4, 2024, all RSUs held by non-employee directors vested.

PAYMENT OF VESTED RESTRICTED STOCK UNITS

A Livent director was permitted to specify, prior to the year in which the RSUs were credited, the date upon which he or she wished to receive payment in Common Stock of any vested RSUs. In the absence of an election, payment would be made upon the earlier of a director’s cessation of service on the Livent Board or a change in control of Livent. The directors’ ability to sell any distributed shares remains subject to the restrictions of Livent’s Director Stock Ownership Policy, which policy is described below.

OTHER COMPENSATION

Livent non-employee directors also received dividend equivalent rights on all RSUs awarded as part of their annual retainers and on any vested RSUs awarded as an annual grant. Such dividend equivalent rights were credited in the form of additional RSUs equal in value to the cash dividends paid to stockholders. The dividend equivalent rights awarded as part of an annual retainer were generally subject to forfeiture on a pro rata basis if a director did not serve on the Livent Board for the full year in respect of which the retainer grant was made, except the forfeiture condition was waived in those circumstances described in the “Retainer and Fees” section above. No other remuneration was paid to Livent non-employee directors for services as a director of Livent. Non-employee directors did not participate in Livent’s nonqualified deferred compensation plan or employee benefit plans.

TABLE OF CONTENTS

DIRECTOR STOCK OWNERSHIP POLICY

Livent established guidelines setting expectations for the ownership of Livent stock by non-employee directors. The Director Stock Ownership Policy required that within five years of being elected to the Livent Board, each non-employee director hold a minimum of five times the value of the annual cash retainer (the “ownership requirement”), in Livent stock. For this purpose, undistributed shares underlying RSUs (both vested and non-vested) were considered “held” by a director. A director had five years from the date of his or her election to the Livent Board to achieve compliance with the ownership requirement. However, even during the initial five-year phase-in period, directors were not permitted to sell shares of Livent Common Stock, other than to satisfy tax liabilities triggered by Livent Company equity grants, unless they were in compliance with the ownership requirement (calculated on the then current annual cash retainer) immediately following any sale of Livent Common Stock. Compliance with the ownership requirement was measured at the time of any proposed sale or disposition of shares of Livent Common Stock by a director, and after the initial five-year phase-in period, on December 31 of each year.

CORPORATE GOVERNANCE

Board Leadership Structure

The positions of Chairman of the Board and Chief Executive Officer of the Company are separate. Mr. Coleman serves as Chairman of the Board and Mr. Graves serves as our Chief Executive Officer and President. We believe that having an independent director serve as the Chairman of the Board is in the best interests of our shareholders and is the appropriate leadership structure for the Company at this time. The separation of roles allows our Chairman of the Board to focus on the organization and effectiveness of the Board. At the same time, it allows our Chief Executive Officer to focus on executing our strategy and managing our operations, performance and risks.

Our Corporate Governance Guidelines provide that the Board should consider the issue of separation of the Chairman and Chief Executive Officer positions under the circumstances prevailing from time to time. When the positions are not separate, a Lead Director shall be appointed.

TABLE OF CONTENTS

BOARD’S ROLE IN OVERSEEING THE RISK MANAGEMENT PROCESS

Successful management of the Company requires the understanding, identification and management of risk. As part of the Company’s risk management process, the Board discusses with management the Company’s major risk exposures, their potential financial impact on the Company, and the steps the Company takes to manage them. The Board also reviews the designation of management responsible for managing such risks, and evaluates the steps being taken to mitigate such risks. The Board’s monitoring role is carried out by either the full Board or a committee that reports to the Board, depending on the risk. Risk oversight that is not allocated to a committee remains with the Board.

The Company has a robust enterprise risk management program that facilitates identification, communication and management of the most significant risks throughout the Company employing a formalized framework in which risk governance and oversight are largely embedded in existing organizational and control structures.

COMMUNICATING WITH THE BOARD

Shareholders and any interested parties may communicate with the Board, the Chairman of the Compensation Committee, the Lead Director, if applicable, the non-employee directors as a group, or any other individual member of the Board as follows: Communications must be in writing, sent care of the Corporate Secretary, Arcadium Lithium plc, 1818 Market Street, Suite 2550, Philadelphia, PA 19103. All communications will be delivered as addressed.

DIRECTOR NOMINATION PROCESS

The Nominating and Corporate Governance Committee is responsible for seeking, screening and recommending to the Board, candidates for Board membership. An executive search firm may also be utilized to identify qualified candidates for consideration. The Nominating and Corporate Governance Committee evaluates candidates based on the qualifications for director described in its Charter and summarized in the section above entitled “Board of Directors—Director Qualifications.” The Nominating and Corporate Governance Committee then presents qualified candidates to the full Board for consideration and selection. The Nominating and Corporate Governance Committee will consider candidates that are recommended by shareholders, applying the same criteria for candidates as discussed above. Nominations by shareholders must be timely made and include other information specified in the Articles of Association.

Any shareholder is entitled to directly nominate one or more candidates for election to the Board in accordance with the Company’s Articles of Association. Notice of a shareholder’s intent to nominate one or more candidates for election as directors at the 2025 Annual Meeting must be delivered to the Company at the address set forth below, no later than the close of business on April 26, 2025 and no earlier than the close of business on March 27, 2025. All nominations, together with the additional information required by the Company’s Articles of Association, must be sent to the Corporate Secretary, Arcadium Lithium plc, 1818 Market Street, Suite 2550, Philadelphia, PA 19103. A copy of the Company’s Articles of Association may be obtained by writing to the Corporate Secretary at the same address.

In addition to satisfying the foregoing requirements under the Company’s Articles of Association, to comply with the universal proxy rules, shareholders who intend to solicit proxies for the annual election of directors in 2025 in support of director nominees other than the Company’s nominees must provide notice that sets forth the information required by Rule 14a-19 under the Exchange Act no later than May 26, 2025.

ANNUAL PERFORMANCE REVIEW

The Nominating and Corporate Governance Committee annually surveys all Directors for evaluation of Board and committee performance overall and in specific areas of responsibility in accordance with the Company’s Corporate Governance Guidelines.

The Board and committees perform annual self-evaluations of their performance. A lengthy questionnaire is sent to each director covering several topics, including Board structure and composition (and what additional skills, if any, may be needed), oversight of director responsibilities and understanding of Company strategy, communications with the CEO and other management, CEO succession planning procedures, performance of committees, and length and content of Board meetings. Each committee member also completes a questionnaire assessing the performance of his or her committees.

Arcadium Lithium plc 25 2024 Proxy Statement

TABLE OF CONTENTS

After obtaining written responses to the questionnaires, the Corporate Secretary conducts a telephone interview with each director to elicit elaboration of views expressed and any other issues the director wishes to discuss. A written report summarizing the responses from the questionnaires and the telephone interviews is presented to the Nominating and Corporate Governance Committee to determine whether any action is required, with a copy of the report also going to the full Board.

The Board is committed to ensuring that its members maintain the necessary skills, qualifications, experience and diversity, and the Board will continue to consider and implement changes to the composition of the Board in light of its annual performance evaluations.

RETIREMENT/RESIGNATION POLICY FOR DIRECTORS

Our Corporate Governance Guidelines provide that a range in director age is desirable to allow staggered retirement and replacement of desired skills on a planned basis with appropriate continuity. While the Board believes that long-tenured directors can be beneficial because of their deep knowledge of the Company acquired through service, the continuity and stability they offer, and their grasp of the historical perspectives that can inform Company strategy, pursuant to our Corporate Governance Guidelines, it is the Board’s policy that non-employee directors shall not stand for re-election at the Company’s annual meeting of shareholders following their 75th birthdays. This policy addresses the Board’s commitment to refreshment, ensuring the Board has appropriate skills as the business evolves and maintaining an appropriate balance of tenure, experience and perspectives.

Under our Articles of Association, if an incumbent nominee fails to receive the required number of votes for re-election, within ninety (90) days after certification of the election results, the Nominating and Corporate Governance Committee of the Board will recommend to the Board whether to accept or reject the resignation or whether other action should be taken and the Board will act on the Nominating and Corporate Governance Committee’s recommendation. In accordance with Arcadium’s director resignation policy, incumbent director nominees are required to tender a contingent resignation which would become effective if (i) the nominee does not receive the required number of votes for his or her re-election and (ii) the Board accepts such resignation.

Non-employee directors are expected to submit their resignation from the Board upon termination of active service as an employee of their current employer or a significant change in responsibilities, unless requested by the Board to continue as a Board member for an agreed period. The Nominating and Corporate Governance Committee will review the situation and make a recommendation to the Board as to whether to accept the resignation.

Employee directors, specifically including the Company’s Chief Executive Officer, are expected to retire from the Board simultaneously with retirement from the Company unless requested by the Board to continue as a Board member for an agreed upon period.

ATTENDANCE AT ANNUAL MEETINGS

The Company’s policy is that all directors are expected to attend the annual meeting of shareholders virtually. Each former Livent director who is currently on the board of the Company attended the 2023 Annual Meeting via live webcast.

RELATED PARTY TRANSACTIONS POLICY

Under the Company’s Related Party Transactions Policy (the “Policy”), any related party transaction may be consummated or may continue only if the Audit Committee or, if the Audit Committee sees fit, another committee of disinterested, independent members of the Board (such committee, the “Committee”), has approved or ratified the transaction in accordance with the guidelines set forth in such policy.

The Policy defines “related parties” to include any person who is or was at any time since the beginning of the last completed fiscal year: an executive officer or director of the Company and their immediate family members, a 5% beneficial owner of the Company’s voting securities and any immediate family member of such owner, or any nominee for director of the Company and the immediate family members of such nominee.

Prior to entering into a related party transaction or once becoming aware of a potential related party transaction, each director, director nominee and executive officer is required to notify the General Counsel of any transaction involving the Company and such a related party that may be a related party transaction and provide all relevant material information regarding the potential related party transaction.

All transactions that are determined to be related party transactions are required to be pre-approved or ratified by the Committee, except that any such transaction that exceeds $120,000 must be pre-approved. The Committee will not approve or ratify a related party transaction unless it has determined that, upon consideration of all relevant information, the transaction is in, or not inconsistent with, the interests of the Company and its shareholders.

FMC Distribution

Livent, a subsidiary of the Company, became a public company upon completion of the initial public offering in 2018 (the “IPO”). On March 1, 2019, Livent became an independent company as a result of FMC’s distribution (the “Distribution”) to FMC shareholders of all 123 million shares of Livent Common Stock that FMC owned as a pro rata dividend on shares of FMC common stock outstanding at the close of business on February 25, 2019.

In connection with the IPO, Livent entered into certain agreements with FMC to provide a framework for its relationship with FMC following the IPO, including but not limited to a Separation and Distribution Agreement, a Shareholders’ Agreement, a Registration Rights Agreement, a Transition Services Agreement, a Tax Matters Agreement, an Employee Matters Agreement, a Trademark License Agreement and several Sublease Agreements. Most of the agreements with FMC have either been terminated or no longer contain material obligations to be performed by Livent. The only agreement that is still active and under which Livent still has material obligations is summarized below, while material agreements are filed as exhibits to the Company’s periodic reports filed with the SEC. The summary below is qualified in its entirety by reference to the full text of such agreement.

Tax Matters Agreement

Livent entered into a tax matters agreement that governs the parties’ respective rights, responsibilities and obligations with respect to taxes, including taxes arising in the ordinary course of business, and taxes, if any, incurred as a result of any failure of the Distribution (or certain related transactions) to qualify as tax-free for U.S. federal income tax purposes. The tax matters agreement also sets forth the respective obligations of the parties with respect to the filing of tax returns, the administration of tax contests and assistance and cooperation on tax matters. Under the tax matters agreement, FMC generally will be responsible for all of Livent’s income taxes that are reported on combined tax returns with FMC or any of its affiliates for tax periods ending on or before December 31, 2017. For the year ended December 31, 2023, Livent recorded a ($0.4) million indemnification liability to FMC for assets where the offsetting uncertain tax position is with FMC and a $1.3 million indemnification asset from FMC regarding uncertain tax positions that are related to Livent’s legacy business before the IPO and for which Livent is indemnified by FMC. Livent will generally be responsible for all other income taxes, that would be applicable to it if it filed the relevant returns on a stand-alone basis, and all non-income taxes attributable to it’s business.

Legal Services

One of our directors, Ms. Heredia, is a partner at the law firm of Allende & Brea. In 2023, the firm provided more than $900,000 of legal services to our two predecessor companies for the performance of legal services, including from Ms. Heredia. The majority of the services that the firm provided, including Ms. Heredia, was to Allkem prior to the merger that formed the Company. While we expect that Allende & Brea will continue to provide legal services to the Company from time to time in the ordinary course of business, Ms. Heredia will cease being involved and will not personally provide any legal services to the Company. Allende & Brea has instituted policies so that Ms. Heredia has no professional involvement in the engagement with the Company. In addition, the amount of legal services that Allende & Brea provides is not a substantial part of the Company’s overall payments for legal services, and the Company will only engage the firm when it determines that the engagement is appropriate, based on the firm’s experience, expertise and efficiency, and in the Company’s best interest.

VI. Executive Compensation

COMPENSATION DISCUSSION AND ANALYSIS

Subsequent to the end of 2023, on January 4, 2024, Livent and Allkem, completed an all-stock merger of equals. The Company, the combined new company, is one of the largest integrated producers of lithium chemicals in the world, with roughly $2.0 billion of combined pro forma revenue in 2023 and a team of approximately 2,400 employees. As a result of the merger, the Company became the successor issuer to Livent pursuant to SEC rules.

In accordance with SEC rules, this Compensation Discussion and Analysis (“CD&A”) describes the philosophy, objectives, process, components and additional aspects of the 2023 executive compensation program of Livent, the predecessor SEC-registered issuer to the Company. Because the merger was completed after December 31, 2023, this CD&A does not describe any of the compensation arrangements for the Company or the Company’s executive officers. This CD&A is intended to be read in conjunction with the tables that immediately follow this section, which provide further historical compensation information for the following named executive officers (“NEOs”), who were the sole executive officers of Livent in 2023:

	Name			Title at Livent
	Paul W. Graves			President and Chief Executive Officer
	Gilberto Antoniazzi			Vice President, Chief Financial Officer and Treasurer
	Sara Ponessa			Vice President, General Counsel and Secretary

This CD&A also discusses decisions of Livent’s Compensation and Organization Committee (the “Livent Committee”) regarding the compensation paid to the NEOs in 2023. During 2023, the members of the Livent Committee were G. Peter D’Aloia (Chair), Michael F. Barry, Pierre Brondeau and Pablo Marcet.

I. Executive Summary

Overview

The primary objectives of Livent’s executive compensation program were to:

•	Link pay to performance over both the short and long terms;

•	Align executive officers’ interests with those of Livent and Livent’s stockholders over the long term, generally through the use of equity as a significant component;

•	Establish components of the program that were consistent with Livent’s business strategy and objectives;

•	Provide market compensation to attract, motivate and retain executive talent; and

•	Achieve all objectives in ways that incorporate due consideration of risk.

Arcadium Lithium plc 32 2024 Proxy Statement

TABLE OF CONTENTS

In light of these objectives, Livent’s compensation plans were designed to reward executive officers for generating performance that achieves Livent and individual goals, and for increasing shareholder returns. When Livent fell short of achieving company and individual goals, Livent’s executive officers’ compensation reflected that performance accordingly.

2023 Select Business Results For Livent

Livent achieved strong year-over-year Revenue, Adjusted EBITDA and margin growth following record 2022 financial results. Livent also made progress on multiple expansion projects related to extracting and processing lithium materials, and, after year-end, completed the merger with Allkem in January 2024 to create a leading global lithium chemicals producer.

Revenue

•

Revenue was $882.5 million, an increase of $69.3 million versus 2022, primarily due to the favorable impact of higher pricing mainly driven by lithium hydroxide sales, partially offset by a net unfavorable volume impact, with a decrease in butyllithium sales volumes offset by favorable lithium carbonate and lithium hydroxide sales volumes.

Net Income

•

Net income was $330.1 million, an increase of $56.6 million compared to the 2022 amount of $273.5 million, primarily due to higher gross margin and an increase in the gain from the sale of Argentina Sovereign U.S. dollar-denominated bonds partially offset by higher restructuring and other charges, which were driven by an increase from transaction-related fees for the merger with Allkem.

Adjusted EBITDA

•

Adjusted EBITDA was $502.5 million, compared to the 2022 amount of $366.7 million, primarily due to the favorable impact of higher pricing, which was driven by lithium hydroxide, and a favorable mix of raw material costs, partially offset by higher selling, general and administration costs. (For the purpose of the 2023 annual incentive plan, the Livent Committee modified Adjusted EBITDA modestly, as described below under “Notable Aspects of Livent’s 2023 Executive Compensation Program”.)

EBITDA is defined as net income plus interest expense, net income tax expense, and depreciation and amortization.

Adjusted EBITDA is defined as EBITDA adjusted for Argentina remeasurement losses, restructuring and other charges, separation-related costs, COVID-19 related costs and other non-recurring losses/(gains).

For a reconciliation of Adjusted EBITDA to the nearest GAAP measure, see the section captioned “Results of Operations–Years Ended December 31, 2023 and 2022” in the Annual Report on Form 10-K for the year ending December 31, 2023.

Notable Aspects Of Livent’S 2023 Executive Compensation Program

The Livent Committee took the following actions with respect to 2023 executive compensation, each as described in more detail under “Compensation Program Components,” below.

Base Salaries

The Livent Committee adjusted annual base salaries for its NEOs to maintain market competitive pay, as determined by reference to comparable positions at the peer group companies.

Annual Cash Incentive Plan

The Livent annual cash incentive plan was comprised of company and individual performance metrics.

For the company component (80% of the annual incentive opportunity), the performance metrics were Adjusted EBITDA (weighted 60%) and key operational goals related to delivery of two expansion projects (weighted 20%).

Arcadium Lithium plc 33 2024 Proxy Statement

TABLE OF CONTENTS

The Livent Committee used an Adjusted EBITDA measure in order to focus executive officers on the critical strategic priority of achieving and improving operating profitability. The Livent Committee set the target at a level that it believed to be challenging and rigorous. Specifically, the Livent Committee set the target for Adjusted EBITDA significantly higher than the 2022 actual result. The Livent Committee also again included two goals related to expanding Livent’s production capacity which, as described below, focused on the development and expansion of carbonate production capacity in Argentina and the production of lithium hydroxide in North Carolina.

Immediately prior to the closing of the merger with Allkem, the Livent Committee determined the level of company performance relative to the annual incentive goals. The Livent Committee modified Adjusted EBITDA for annual incentive plan purposes modestly from $502.5 million to $504 million to remove the effects of foreign exchange rate fluctuations versus rates assumed in the budget and by adjusting certain costs associated with the ramp up and commissioning activities of the two expansion facilities in Bessemer City and Argentina if higher or lower than assumed in the budget. Based on this financial result, the Livent Committee determined that:

Livent’s Adjusted EBITDA, which represented 60% of the Company Measures, was achieved at 85% of target, yielding a 0.45 achievement level. In light of market pricing conditions, and the Board’s related strategic considerations surrounding the timing of expansion project operations commencement, the Livent Committee adjusted the achievement rating modestly from 0.45 to 0.50 to account for the decision that was in the best interest of shareholders but that nevertheless affected results.

•	On the delivery of expansion goals, which represented 20% of the Company Measures, Livent achieved: 0.96 with respect to the Argentina Expansion and 0.80 with respect to the North Carolina Expansion, yielding a combined 0.92 achievement level.

•	Combined, the overall achievement level for Company Measures was 0.60.

For the individual component, which represented 20% of the total opportunity, the targets, achievements, and payouts of the NEOs varied, but were earned at a rating of 1.5 (on a rating scale of 0.0 to 2.0, where 1.0 is the target).

Long-Term Incentives

In the first quarter of 2023, the Livent Committee again granted the NEOs performance-based restricted stock units (“PSUs”), options, and time-based restricted stock units (“RSUs”). The PSUs used relative Total Shareholder Return (“TSR”) as a metric for the 2023-25 performance period. The Livent Committee allocated 25% of the long-term incentive equity opportunity to the relative TSR PSUs. The other elements of the 2023 long-term incentives consisted of 25% stock options and 50% RSUs. Pursuant to the Transaction Agreement, the outstanding equity awards held by NEOs were treated as follows:

•	Stock options were assumed by the Company and converted to equivalent awards with respect to Company stock and remain subject to the same terms and conditions.

•	Time-based RSUs were assumed by the Company, with a pro rata portion vesting in Company shares following such assumption, and with the unvested portion converted to equivalent awards with respect to Company stock and remaining subject to the same terms and conditions.

•	PSUs fully vested at target. The vesting of the PSUs was accelerated from January 4, 2024, the closing of the merger, to December 22, 2023.

2023 Livent Say On Pay Vote

At the 2023 annual meeting of Livent’s stockholders, Livent’s stockholders approved the compensation of NEOs on an advisory basis, with approximately 86.6% of the votes cast “For” such approval. The Livent Committee interpreted stockholder approval of the executive compensation program at such a level as indicating that a substantial majority of stockholders viewed Livent’s executive compensation program, plan design and governance as continuing to be well aligned with stockholder interests, their investor experience and business outcomes.

To ensure investor views were incorporated into the planning process, Livent engaged with stockholders on an ongoing basis to gather their perspectives. Through this stockholder outreach, Livent established important feedback channels that served as a valuable resource for ongoing input from Livent stockholders.

II. COMPENSATION PHILOSOPHY

Pay-for-performance: Livent’s program was designed to motivate its executive officers to achieve goals by closely linking their performance and Livent’s performance to the compensation they receive. As such, a significant portion of the total compensation of its executive officers was based on measures that supported Livent goals, as well as on the executive officer’s individual performance. To tighten this link, Livent defined clear and measurable quantitative and qualitative objectives that, in combination, were designed to improve Livent’s results and returns to stockholders.

Alignment of executive officers’ interests with those of Livent and its stockholders: A significant portion of Livent’s executive officers’ overall compensation was in the form of equity-based compensation. Livent used equity as the form for long-term incentive opportunities in order to motivate and reward executive officers to (i) achieve multiyear strategic goals and (ii) deliver sustained long-term value to stockholders. Using equity for long-term incentives creates strong alignment between the interests of executive officers and those of stockholders, as it provides executive officers with a common interest with stockholders in stock price performance and it fosters an ownership culture among executive officers by making them stockholders with a personal stake in the value they are being motivated to create.

Provide market competitive pay to attract and retain talent: Livent had to compete in the market for executive talent. Livent sought executive officers and managers to lead the business and carry out the strategy who have diverse experience, expertise, capabilities and backgrounds. In recruiting executive officers and determining competitive pay levels, Livent referenced the market median amounts and compensation structures of executive officers of the companies in Livent’s peer group and as shown in general industry surveys. Executive officers’ total compensation may deviate from the level referenced in the peer group or surveys in order to attract or retain certain individuals or reflect their respective characteristics or performance.

Risk management: While Livent designed the executive compensation program to create incentives for executive officers to deliver high performance. Livent also simultaneously sought to minimize risk by striving to reduce undue pressure on, or incentives for, executive officers to take excessive risks to achieve goals and receive rewards. Livent sought to include mechanisms intended to mitigate such risk, including (i) placing maximum limits on short- and long-term incentive pay-outs and awards; (ii) measuring performance using key performance indicators that by design have lower potential to promote excessive risk-taking; (iii) utilizing a mix of equity vehicles with longer term vesting; (iv) requiring clawback of compensation payments under certain plans or in certain circumstances; and (v) maintaining executive officer stock ownership guidelines. The Livent Committee determined that its compensation policies and programs did not give rise to inappropriate risk taking or risks that were reasonably likely to have a material adverse effect on Livent.

Compensation Program Governance

Livent assessed the effectiveness of the executive compensation program from time to time and reviewed risk mitigation and governance matters, which included the following best practices:

What We Do
	Pay for Performance	The majority of total executive compensation opportunity was variable and at-risk.
	Independent Compensation Consultant	Engaged an independent compensation consultant to provide information and advice for use in the Livent Committee’s decision-making.
	Clawback	Incentive compensation subject to clawback if Livent restated its financials due to material non-compliance with a financial reporting requirement. Equity awards could also be clawed back if a participant engaged in serious misconduct, was terminated for cause, or competed with Livent.
	Stock Ownership Guidelines	Adopted guidelines for executive officers to maintain meaningful levels of stock ownership.
	Cap Bonus Payouts and Equity Grants	Annual incentive plan and equity awards had upper limits on the amounts of cash and equity that may be earned.
	Double Trigger Change-in-Control Severance	Livent entered into agreements with NEOs that provide certain financial benefits if there was both a change in control and termination of employment (a “double trigger”). A change in control alone did not trigger severance pay.

Arcadium Lithium plc 35 2024 Proxy Statement

TABLE OF CONTENTS

What We Don’t Do
	No Repricing of Underwater Stock Options	The equity plan expressly prohibited repricing of stock options or exchanges of underwater stock options without shareholder approval.
	No Excessive Perks	Did not provide large perquisites to executive officers.
	No Excise Tax Gross-Ups	Did not provide excise tax gross-ups on change-in-control payments.
	No hedging or pledging of Company shares	Did not permit executive officers and directors to pledge or hedge their shares.

III. COMPENSATION DETERMINATION PROCESS

Role of the Committee

The Livent Committee established the compensation philosophy and objectives, determined the structure, components and other elements of executive compensation, and reviewed and approved the compensation of the NEOs or recommended it for approval by the Board of Directors.

The Livent Committee structured the executive compensation program to accomplish articulated compensation objectives in light of the compensation philosophy described above.

In accordance with its charter, the Livent Committee established total compensation for the CEO (generally at its February meeting). The Livent Committee reviewed and evaluated the performance of the CEO and developed base salary and incentive compensation recommendations. The CEO did not play any role with respect to any matter affecting his own compensation and was not present when the Livent Committee discussed and formulated their recommendation for his compensation.

With the input of the CEO, the Livent Committee also established the compensation for all the other executive officers. As part of this process, the CEO evaluated the market competitiveness of the various components of compensation and the performance of the other executive officers annually and made recommendations to the Livent Committee in February regarding the compensation of each executive officer. The CEO’s input was particularly important in connection with base salary adjustments and the determination of each executive officer’s individual goals under the annual incentive plan. The Livent Committee gave significant weight to the CEO’s recommendations in light of his greater familiarity with the day-to-day performance of his direct reports and the importance of incentive compensation in driving the execution of managerial initiatives developed and led by the CEO. Nevertheless, the Livent Committee or the Board made the ultimate determination regarding the compensation for the executive officers.

Pursuant to its charter, the Livent Committee was permitted to delegate its authority to subcommittees, other than any power or authority required by law or stock exchange requirements to be exercised by the Livent Board of Directors or the Livent Committee.

Role of the Independent Compensation Consultant

The Livent Committee recognized the importance of obtaining objective, independent expertise and advice in carrying out its responsibilities. The Livent Committee had the power to retain an independent compensation consultant to assist it in the performance of its duties and responsibilities.

The Livent Committee retained Aon’s Human Capital Solutions practice, a division of Aon, as its independent compensation consultant. Aon reported directly to the Livent Committee, and the Livent Committee had the sole authority to retain, terminate and obtain the advice of Aon at Livent’s expense. The Livent Committee selected Aon as its consultant because of the firm’s expertise and experience.

The Livent Committee worked with Aon to: (i) assess the executive compensation objectives and components; (ii) review considerations, market practices, and trends related to short-term annual incentive plans and long-term equity and other incentive plans; (iii) collect comparative compensation levels for each of the executive officer positions, as needed; and (iv) review the equity compensation strategy.

Arcadium Lithium plc 36 2024 Proxy Statement

TABLE OF CONTENTS

While the Livent Committee took into consideration the review and recommendations of Aon when making decisions about the executive compensation program, ultimately, the Livent Committee made its own independent decisions about compensation matters.

The Livent Committee assessed the independence of Aon pursuant to SEC and NYSE rules. In doing so, the Livent Committee considered each of the factors set forth by the SEC and the NYSE with respect to a compensation consultant’s independence. The Livent Committee also considered the nature and amount of work performed for the Livent Committee and the fees paid for those services in relation to the firm’s total revenues. Based on its consideration of the foregoing and other relevant factors, the Livent Committee concluded that there were no conflicts of interest, and that Aon is independent.

For 2023, in determining the independence of Aon, the Livent Committee considered independence in light of the independence factors set forth in the SEC rules and NYSE listing standards. In total, fees paid to Aon during 2023 for services not related to Aon’s work with the Livent Committee, such as global commercial risk brokerage services, were approximately $898,148. The engagement of Aon to performance such other services was recommended by management and was reviewed by the Livent Committee, including as part of its review of Aon’s independence. Fees paid to Aon during 2023 for services related to recommending the amount and form of executive and director compensation were approximately $588,764.

In terms of assessing independence, the Livent Committee also gave credit to the safeguards that Aon’s executive compensation practice has put in place to maintain its independence. The Livent Committee also considered that no business or personal relationships exist between any members of the consultants’ teams advising the Company on the one hand, and the Company, any members of the Livent Committee or any executive officers on the other hand, other than in connection with the services provided. Therefore, the Livent Committee has concluded that Aon is independent, as no conflict of interest exists between Aon and the Company.

Executive Compensation Competitive Market Information

In making determinations about executive compensation, the Livent Committee believed that obtaining relevant market data was important, because it served as a reference point for making decisions and provided very helpful context. When making decisions about the structure and component mix of the executive compensation program, the Livent Committee considered the structure and components of, and the amounts paid under, the executive compensation programs of other comparable peer companies, as derived from public filings and other sources.

The Livent Committee, with the assistance of Aon, its independent compensation consultant, developed a peer group in 2022 for purposes of 2023 compensation. The criteria used to determine the peer group included: companies in the chemicals sector traded on U.S. exchanges; revenue in the range of 1/3 to 3 times Livent’s revenue; market capitalization in the range of 1/3 to 3 times Livent’s market capitalization; and primarily in the specialty chemicals industry with additional revenues from outside the U.S.

Based on these criteria and considerations, the peer group selected for decisions relating to 2023 executive compensation, as approved by the Livent Committee, consisted of the following 21 companies:

Albemarle Corporation (ALB)*	CVR Partners, LP(UAN)	Innospec Inc. (IOSP)
American Vanguard Corporation (AVD)	Ecovyst Inc. (ECVT)	Intrepid Potash, Inc. (IPI)
Amyris, Inc. (AMRS)	Element Solutions Inc. (ESI)*	Mineral Technologies, Inc. (MTX)*
Ashland Inc. (ASH)*	FutureFuel Corporation (FF)	Quaker Chemical Corporation (KWR)
Balchem Corporation (BCPC)	GCP Applied Technologies, Inc. (GCP)	Sensient Technologies Corporation (SXT)
Chase Corporation (CCF)	Hawkins, Inc. (HW KN)	Sisecam Resources LP (SIRE)
Compass Minerals International, Inc. (CMP)	Ingevity Corporation (NGVT)	Tredegar Corporation (TG)

New peer for 2023 peer group. Albemarle Corporation, Ashland Inc., Element Solutions Inc. and Mineral Technologies, Inc. met the peer group criteria and therefore were added for 2023. Kraton Corporation and Trecora Resources, who were included in the peer group for 2022, were removed for purposes of the 2023 peer group as they no longer met the applicable criteria.

Livent Corporation	$3,724.4	$472.2
Rank	83rd%	18th%

In addition to the criteria above, the Livent Committee also referenced general and specific industry surveys from other sources. The Livent Committee determined that the appropriate market reference continued to be the 50th percentile. The market data are used as a reference point and to provide information on the range of competitive pay levels and current compensation practices in Livent’s industry.

The Livent Committee believed that the compensation practices of the peer group provided it with appropriate compensation reference points for evaluating the 2023 compensation of the NEOs. Consistent with best practices for corporate governance, the Livent Committee historically reviewed the peer group annually.

IV. COMPENSATION PROGRAM COMPONENTS

2023 Components in General

The Livent Committee selected the components of compensation set forth in the chart below to achieve Livent’s executive compensation program objectives. The Livent Committee regularly reviewed all components of the program to verify that each executive officer’s total compensation was consistent with the compensation philosophy and objectives and that the component was serving a purpose in supporting the execution of the strategy. Taking into consideration the 2023 grants of equity to the CEO and other NEOs, the majority of each executive officer’s compensation was variable and at-risk.

Long-term incentive equity awards are prospective in nature and intended to tie a substantial portion of an executive’s pay to creating long-term stockholder value. The Livent Committee structured the 2023 long-term incentive opportunity with PSUs, stock options and RSUs in order to motivate executive officers to achieve multi-year strategic goals and deliver sustained long-term value to stockholders, and to reward them for doing so.

Element	Description	Additional Detail
Base Salary	Fixed cash compensation. Determined based on each executive officer’s role, individual skills, experience, performance, and external market value.	Base salaries are intended to provide stable compensation to executive officers, allow Livent to attract and retain skilled executive talent and maintain a stable leadership team.
Short-Term Incentives: Annual Cash Incentive Opportunities	Variable cash compensation based on the level of achievement of pre-determined annual corporate and individual goals. 80% of the award is based on corporate objectives and 20% is based on individual measures. For the corporate objectives and individual measures, cash incentives are capped at a maximum of 200% of each NEO’s target opportunity. Performance against the corporate objectives must exceed a threshold level of performance in order to earn any credit toward a payout with respect to that goal.	Annual cash incentive opportunities are designed to ensure that executive officers are motivated to achieve Livent’s annual goals; payout levels are generally determined based on actual financial results and non-financial objectives, and individual goals specific to each NEO.

Links with stockholder value creation; aligns with stockholders; filters out macroeconomic and other factors not within management’s control.

2023 Target Pay Mix

The target pay mix supported the core principles of Livent’s executive compensation philosophy of pay for performance and aligning executive officers’ interests with those of Livent and its shareholders, by emphasizing short- and long-term incentives.

The following charts outline the Livent Committee’s allocation of annual target total direct compensation payable to the CEO and to other NEOs. The Livent Committee allocated compensation among (i) base salary, (ii) a short-term annual cash incentive opportunity and (iii) long-term annual equity.

A sizeable majority of target total direct compensation was variable, at-risk pay, consistent with Livent’s pay-for-performance philosophy. Specifically, in 2023, 78% of the CEO’s target total direct compensation was at-risk compensation, and 64%, on average, of the target total direct compensation of the other NEOs was at-risk compensation. Livent considered compensation to be “at risk” if it is subject to performance-based payment or vesting conditions or if its value depended on stock price appreciation.

The percentages of target total direct compensation as calculated above are based on the annualized 2023 base salary, the 2023 annual cash incentive compensation opportunity (assuming achievement at the target level), and the grant date fair value of the annual equity grants.

Base Salary

Base salaries provided fixed compensation to Livent’s executive officers and helped to attract and retain the executive talent needed to lead the business and maintain a stable leadership team. Base salaries were individually determined according to each executive officer’s areas of responsibility, role and experience, and vary among executive officers based on a variety of considerations, including skills, experience, achievements and the competitive market for the position.

Arcadium Lithium plc 39 2024 Proxy Statement

TABLE OF CONTENTS

In 2023, the Livent Committee adjusted the base salaries of the NEOs to maintain market competitive pay, as determined by reference to comparable positions at the peer group companies.

NEO	2023 Base Salary	2022 Base Salary	% Change
Paul W. Graves	$860,000	$825,000	4.2%
Gilberto Antoniazzi	$450,000	$420,000	7.1%
Sara Ponessa	$390,000	$360,000	8.3%

Annual Incentive Plan

The annual incentive plan for executive officers was a cash-based plan that rewarded Livent’s NEOs for the achievement of key short-term objectives. The structure of the annual cash plan incentivized NEOs to achieve annual financial and operational results that the Livent Committee viewed as critical to the execution of Livent’s business strategy.

For the NEOs, the amount of the payout, if any, under the annual incentive plan was based on achievement against two categories of performance measures: Company Measure and Individual Measures.

Target Opportunities

The Livent Committee determined a target cash incentive opportunity for each NEO under the annual cash incentive plan by taking the individual’s base salary and multiplying it by the individual’s target incentive percentage. The target incentive percentages for Mr. Graves and Ms. Ponessa remained unchanged since 2018. The Livent Committee approved a 5% increase to Mr. Antoniazzi’s target incentive percentage in 2023 based on his performance and the target percentages in the competitive market for the position.

	2023 Threshold Level Opportunity	2023 Target Level Opportunity (as % of Applicable Base Salary)	2023 Maximum Level Opportunity (as % of Applicable Base Salary)
Paul W. Graves	0%	100%	200%
Gilberto Antoniazzi	0%	65%	130%
Sara Ponessa	0%	60%	120%

Company Measures

The amount of the payout, if any, under the Company Measure component of the Annual Incentive Plan was based on Livent’s achievement against 1) a financial metric and 2) the execution of two expansion projects. The financial metric, which represented 60% of the target annual incentive opportunity, was again Adjusted EBITDA. The two expansion project metrics related to (a) the development and expansion of carbonate production capacity in Argentina through safety, timeliness of completion, operational readiness and progress on engineering studies (15%), and (b) engineering milestones for the production of lithium hydroxide at a new facility in North Carolina (5%). The Company Measures collectively represented 80% of the annual cash incentive opportunity, underscoring the emphasis on Livent performance.

The Livent Committee continued to use Adjusted EBITDA as the financial metric for 2023 in order to focus executive officers on the critical strategic priority of achieving and improving operating profitability.

The Adjusted EBITDA metric gave a clear line of sight into how achieving operating goals drives performance and generates rewards. The Livent Committee believed that this non-GAAP measure was useful as an incentive compensation performance metric because it excluded various items that do not relate to or were not indicative of operating performance for Livent.

The Livent Committee again included the expansion project goals in 2023 in order to focus executive officers on the critical strategic priority of delivery of two key expansion projects in order to grow Livent’s ability to grow capacity and produce more lithium carbonate and lithium hydroxide.

Arcadium Lithium plc 40 2024 Proxy Statement

TABLE OF CONTENTS

EBITDA is defined as net income plus interest expense, net income tax expense, and depreciation and amortization.

Adjusted EBITDA is defined as EBITDA adjusted for Argentina remeasurement losses, restructuring and other charges,

separation-related costs, COVID-19 related costs and other non-recurring losses/(gains). The Non-GAAP measure Adjusted EBITDA should not be considered as a substitute for net income or cash flows from continuing operations or other measures of profitability or liquidity determined in accordance with GAAP. For a reconciliation of Adjusted EBITDA to the nearest GAAP measure, see the section captioned “Results of Operations–Years Ended December 31, 2023 and 2022” in the Annual Report on Form 10-K for the year ending December 31, 2023.

Target, Threshold and Maximum Performance Levels

The Livent Committee set the target for Adjusted EBITDA at a level that it considered rigorous and challenging and that took into account the relevant risks and opportunities of Livent’s business. In particular, the Livent Committee reviewed Livent’s 2023 annual operating budget that resulted from Livent’s detailed budgeting process and evaluated various factors that might affect whether the budget targets could be achieved, including the risks to achieving certain preliminary objectives that were necessary prerequisites to achieving the budget targets.

Considering these factors, the Livent Committee set the 2023 target for Adjusted EBITDA at $545 million, a 101 percent increase in Adjusted EBITDA over 2022 Adjusted EBITDA results as reported for purposes of the 2022 annual incentive plan.

Having set the target at double the level of prior year actual results (for annual incentive plan purposes), the Livent Committee also set the threshold and maximum performance levels for Adjusted EBITDA. For 2023, the Livent Committee set threshold at what it believed to be a high level of performance equating to approximately just above 83% of the target for Adjusted EBITDA. The Livent Committee set the maximum level of performance equating to approximately 116% of target for Adjusted EBITDA, a level that required exceptionally strong performance and represented a significant challenge.

The Livent Committee also set target, threshold and maximum performance levels for each of the two expansion project goals. The Argentina expansion project goals were based on achieving high levels of safety, keeping to the timeline for delivery of the expansion project, staffing the facility and retaining employees, and timely progress on engineering studies. The North Carolina expansion project performance curve was based on the timeliness of completing engineering milestones.

Payout Levels

Payout levels represent the amount to be paid to NEOs based on the level of actual performance relative to the goals. In order to motivate performance and underscore the importance of achieving, or closely approaching, the performance goals at this critical time in Livent’s development, the Livent Committee set the payout at 0% for achievement below the threshold level of performance. For performance between the target level and the maximum level, the payout ranges from 100% of the target opportunity to 200% of the target opportunity. Achievement above the maximum level is capped at the maximum payout of 200% of target. For the Adjusted EBITDA metric, performance between the threshold, target and maximum levels was calculated in a straight-line manner.

2023 Achievements for Company Measures

For 2023, Adjusted EBITDA increased meaningfully as compared to 2022, primarily due to the favorable impact of higher pricing mainly driven by lithium hydroxide and a favorable mix of raw material costs partially offset by higher selling, general and administration costs. For purposes of the 2023 annual incentive plan, the Livent Committee normalized the Adjusted EBITDA result from $502.5 million to $504 million by excluding the effect of foreign exchange rate fluctuations versus rates assumed in the budget, and by adjusting certain costs associated with the ramp up and commissioning activities of the two expansion facilities in Bessemer City and Argentina if higher or lower than assumed in the budget. The actual result landed between the threshold and target levels. In light of market pricing conditions, and the Board’s related strategic considerations surrounding the timing of expansion project operations commencement, the Livent Committee adjusted the achievement rating modestly from 0.45 to 0.50 (i.e., 45% to 50%) to account for the decision that was in the best interest of shareholders but that nevertheless affected results.

Individual Measures

The Livent Committee also established Individual Measures under the annual incentive plan, which represented 20% of the annual incentive target opportunity. The Individual Measures were set in the beginning of 2023, prior to the completion of the due diligence process for the merger with Allkem, and were designed to align with Livent’s strategic and operating initiatives. NEOs were eligible to receive anywhere between 0% - 200% of target for this portion of the award, based on performance against individual goals. The NEOs 2023 Individual Measures are set forth below:

2023 Achievements For Individual Measures

For the Individual Measures component, the Livent Committee determined that Mr. Graves, Mr. Antoniazzi, and Ms. Ponessa each earned 150% of their individual targets, based on the performance assessments described below:

•

Mr. Graves: Led the Livent strategy to engage in the merger of equals transaction with Allkem to create the Company. He developed the strategic rationale underlying the merger of equals structure, the early assessment of potential synergies and the evaluation of shareholder acceptance for the combined company. He directed the comprehensive due diligence for the merger, spanning financial, operational, regulatory, legal and cultural workstreams. He led the negotiations for the merger transaction agreement, providing the equity framework for both legacy companies and the governance and tax structure of the combined entity, with consideration for both employee and shareholder interests. Once a merger agreement was reached, Mr. Graves led the team responsible for the complex cross-border regulatory approval processes, as well as global shareholder engagement to secure shareholder approval in both the U.S. and Australia. He then laid the framework for pre-integration planning during the second half of 2023, to the extent it was permitted under regulatory guidelines, which focused on the combined company’s operating model across Finance, Legal, Operations and Capital Projects. He also led the work to assess the cultural compatibility of the two legacy companies to identify areas of focus and risk for the integration. Mr. Graves accomplished all this while also delivering Livent’s 2023 financial, safety, quality, expansion and sustainability objectives. He helped Livent achieve full year 2023 financial performance which exceeded its record results in 2022, while navigating the company through a challenging business environment when the company was impacted by the sharp decline in lithium pricing which affected the entire lithium industry. The commercial structure of Livent’s long-term contracts with leading automotive OEMs and battery makers helped mitigate the overall impact of the pricing declines, resulting in Year over Year revenue growth of 9% and Adjusted EBITDA growth of 37%. On the commercial front, Mr. Graves helped Livent negotiate terms of key customers contracts. He also helped Livent establish key industry partnerships, one with Sakuu for the successful application of Livent’s LIOVIX® formulation in Sakuu’s advanced 3D-printed batteries and state-of-the-art manufacturing process, and another with IliAD Technologies for its next-generation Direct Lithium Extraction (DLE) platform. Safety continued to be top priority for Mr. Graves, and in 2023, he helped the company achieve a Total Recordable Injury Rate (TRIR) of .38. Mr. Graves also led Livent’s continued focus on quality and customer qualifications of Lithium Hydroxide from its new 5,000 metric ton conversion unit in Bessemer City, which was important to key automotive OEM customers looking to source Inflation Reduction Act (IRA) compliant materials and regionalize their supply chains. Livent’s other expansion projects also progressed under Mr. Graves’ leadership. Over the course of the year, the company took important steps to advance its Phase I Lithium Carbonate expansion in Argentina, albeit at a slower pace than expected, and progressed engineering for Phase II. It also completed a 15,000 metric ton Lithium Hydroxide conversion site in a new location in Zhejiang, doubling the company’s production capacity in China. With regards to the development of hard rock lithium resources, Mr. Graves served on the Board of Nemaska Lithium and led the negotiations for Livent to provide significant technical and commercial expertise to Nemaska Lithium, including engaging in exclusive sales and marketing efforts on behalf of Nemaska Lithium. He also led the team responsible for the sale of Livent’s butyllithium manufacturing site in Patancheru, India, to Neogen Chemicals, a buyer that was committed to the pharmaceutical and specialty chemicals market in India, and like Livent, had a strong commitment to employees and local communities. Mr. Graves continued to lead Livent’s Sustainability strategy, which included completing a multi-year voluntary study on sustainable water use in Andean salars and aquifers (sponsored by BMW and BASF); forming an Energy Transition Team to identify opportunities to work with stakeholders and partners to connect Livent’s Fenix operations with energy grids in Argentina; and continued optimization of existing processes to drive long-term intensity improvements in greenhouse gas (GHG) emissions, waste disposed and water use across the company’s operations, while improving its energy mix. Under Mr. Graves’ leadership, the company also completed its

first ever global Scope 3 screening of Livent’s GHG emissions; provided its first disclosure of global NOx and SOx air pollutants and delivered on its goal of completing ISO-compliant Life Cycle Assessments for Livent’s key products by 2025, ahead of schedule. For its sustainability achievements, Livent was recognized by Newsweek in its list of “America’s Most Responsible Companies 2024.” Mr. Graves also continued to lead Livent’s focus on talent, improving the company’s workforce profile in gender and racial diversity, fostering an environment of inclusiveness, and strengthening programs for attracting, retaining and developing talent as the company prepared for the merger with Allkem.

Mr. Antoniazzi: Helped steer the negotiations with Allkem management, including the deal strategy and construction of transaction agreements and structure, which led to the cross-border merger of equals deal with Allkem and the creation of the Company. He led critical aspects of the transaction including the approach for an all-stock structure, the tax strategy of the merged company, and the financial filings in the United States required for shareholders’ approval. Mr. Antoniazzi also directly engaged with both the Australian and US investor base to gather support for shareholders’ approval of the transaction. Beyond his involvement in the transformative Livent-Allkem merger transaction, Mr. Antoniazzi focused on driving a record year of financial performance for the Livent legacy company in 2023, while helping navigate the company through a lithium market downturn. He operated strong cash-flow discipline securing all needed funding to advance capacity expansion projects across the globe, leading to the completion of construction of both a new 10,000 metric ton capacity lithium carbonate plant in Argentina and an additional 15,000 metric ton lithium hydroxide plant in China. He led the renewal of the company’s $500 million dollar revolver credit facility. On the Nemaska Lithium project front, Mr. Antoniazzi supported the renegotiation of the shareholders agreement with Investissement Québec which resulted in the consolidation of Nemaska Lithium’s financial results with Livent’s (now the Company’s) financial results. Mr. Antoniazzi has also helped guide the company’s commercial pricing strategy, resulting in both greater profitability and cash-flow predictability for the business. On the governance front, Mr. Antoniazzi continued to lead the company’s timely and compliant financial reporting, including one-time related financial filings associated with both the merger transaction as well as the consolidation of Nemaska Lithium’s results. He was actively engaged in promoting a diverse workforce, including planning for talent retention and development for the newly formed company.

•

Ms. Ponessa: Successfully led and executed all legal, regulatory (securities, antitrust, FDI, etc.), and compliance aspects of the complex cross-border Livent/Allkem merger of equals transaction and pre-closing integration activities. Ms. Ponessa led the legal deal strategy, project management, and conflict resolution activities to achieve the objectives and timeline to closing of the transaction. Along with her team she structured and negotiated project and commercial support arrangements for Nemaska to facilitate enhanced operational oversight in compliance with antitrust laws. She also oversaw negotiations of strategic supply and procurement agreements to support commercial and expansion strategy. During the year she was a key contributor to the legal and strategic aspects of business development activities, including strategic investment and R&D collaboration transactions. Working cross functionally she provided strategic management of commercial, labor, and other disputes to minimize litigation risk and financial exposure. Ms. Ponessa also provided executive oversight aimed at enhancing the risk-based approach to Livent’s compliance program, including formal transition to the best practice approach of cross-functional annual risk reviews of legal, compliance, and regulatory matters in coordination with enterprise risk management processes. Ms. Ponessa has provided executive legal guidance on compliance due diligence and pre-closing integration planning activities relating to the combined company’s compliance program. She actively provided executive mentorship for Livent’s Global Women’s Network (GWN), including her serving as a speaker for the Argentina GWN event, and global International Women’s Day event. She was a leader in facilitating diverse slates of candidates for open roles which resulted in the hiring of highly qualified diverse candidates into senior Law Department roles in China and US. Ms. Ponessa prioritized the development of her team by holding department-wide legal and compliance trainings with guest speakers, and individual coaching/outside training to enhance the leadership and management skills of team members. She designed a Day 1 Company Law Department and compliance program structure to support the combined business in an effective and agile manner and oversaw the successful execution of all other legal and compliance integration activities, including the timely and flawless closing of the merger of equals transaction and effective preparation of all governance documents and processes for the Company Board of Directors and Board Committees. She effectively advised management, the Board and Committees on legal, compliance, and governance matters, including those associated with the merger of equals transaction and U.S. securities and NYSE requirements.

Payout Determination

As described above, the Livent Committee verified achievement relative to the targets for the Company Measures and the Individual Measures to determine the respective performance levels. The Livent Committee then added the amounts for the

Arcadium Lithium plc 44 2024 Proxy Statement

TABLE OF CONTENTS

two portions together to determine the total 2023 annual incentive plan payout for each NEO. The Livent Committee then presented the determination of the annual incentive plan payout amounts to the Livent Board for its review.

In light of the timing of the consummation of the Livent-Allkem merger of equals on January 4, 2024, the Livent Committee determined performance for purposes of the 2023 annual incentive plan on December 13, 2023, prior to the consummation of the merger. The Livent Committee reviewed actual performance results through November and forecasted results through year end to determine full year performance based on such results, in the absence of actual full-year performance results.

The total payout under the Livent Annual Incentive Plan for each NEO for 2023 is reflected in the table below.

NEO	Target Incentive	Company Measures: 80% of Target Incentive	Company Measures Rating	Company Measures Incentive Payout Amount	Individual Measures: 20% of Target	Individual Measures Rating	Individual Measures: Incentive Payout Amount	Total 2023 Incentive Payout Amount
Paul W. Graves	$860,000	$688,000	0.60	$416,240	$172,000	1.50	$258,000	$674,240
Gilberto Antoniazzi	$292,500	$234,000	0.60	$141,570	$58,400	1.50	$87,750	$229,320
Sara Ponessa	$234,000	$187,200	0.60	$113,256	$46,800	1.50	$70,200	$183,456

Long-Term Incentives

The third and largest component of the Livent executive compensation program was long-term equity incentives. Long-term equity incentive awards are prospective in nature and intended to tie a substantial portion of an executive’s pay to creating long-term stockholder value. The Livent Committee designed the long-term incentive opportunity to motivate and reward Livent’s executive officers to achieve multi-year strategic goals and to deliver sustained long-term value to stockholders. The long-term incentives create a strong link between payouts and performance, and a strong alignment between the interests of executive officers and the interests of Livent’s stockholders. Long-term equity incentives also promote retention, because executive officers will only receive value if they remain employed over the required term, and they foster an ownership culture among Livent’s executive officers by making them stockholders with a personal stake in the value they are intended to create.

Equity Vehicles and Mix: PSUs, Stock Options and RSUs

The mix of long-term incentives granted to the NEOs in 2023 is shown below:

Rationale for Use

PSUs

• 25%

• 3-year cliff

• 2023-2025 Relative TSR

• TSR ties executive officer compensation to shareholder value creation

• Use of relative TSR to filter macroeconomic and other factors where management may have limited ability to influence

Stock Options

• 25%

• 3-year cliff

• Exercise price: closing price on grant date

• 10-year term

• Share price appreciation

• Prioritizes increasing shareholder value

• Promotes long-term focus

RSUs

• 50%

• 3-year cliff

• Value of stock

• Aligns with stockholders
• Promotes retention

• Provides value even during periods of stock price or market underperformance

The Livent Committee structured the mix of equity vehicles and the relative weight assigned to each type of award for the following reasons: 1) to motivate relative stock price outperformance over the long term through the PSUs, 2) to motivate stock price appreciation over the long term through stock options, which deliver value only if the stock price increases, and 3) to ensure some

TABLE OF CONTENTS

amount of value delivery through the RSUs, which were complementary because they have upside potential but deliver some value even during periods of stock price underperformance, while also reinforcing an ownership culture and commitment to Livent. All equity awards were granted under the Livent Incentive Compensation and Stock Plan.

Long-Term Incentive Opportunities

The Livent Committee established long-term incentive opportunities for each of the NEOs in February 2023, considering the following:

•	the values of, allocations to, and proportion of total compensation represented by, the long-term incentive opportunities at the peer group companies;

•	individual performance and criticality of, and expected future contributions of the NEO;

•	time in role, skills and experience; and

•	retention considerations.

2023 Grants of PSUs, Stock Options and RSUs

As described above, the Livent Committee established the mix of equity vehicles for 2023 as 25% PSUs, 25% stock options and 50% RSUs.

In determining the target amount of PSUs awarded to meet the compensation level approved for an NEO, the portion of the award value related to PSUs was divided by the Monte Carlo valuation on the date of grant.

The PSUs had a three-year performance period, beginning January 1, 2023 and ending December 31, 2025. The PSUs used relative Total Shareholder Return, or relative TSR, as a metric for the 2023-25 performance period. Livent’s TSR was ranked relative to companies in the Russell 3000 Chemical Supersector Index. Comparing Livent’s performance against the TSR of a peer group rewarded NEOs for driving performance greater than or equal to peers, as the peer group was all generally subject to the same market factors as Livent. The Livent Committee selected the Russell 3000 Chemical Supersector as the peer group because it was made up of a large roster of durable companies that were similar in size to Livent. The actual number of PSUs earned would be based on the percentile rank of Livent’s TSR relative to the TSRs of the companies in the peer group as described in the table.

Performance Level	TSR Percent Rank	Earned Percentage
Below Threshold	Below 25^thPercentile	0%
Threshold	25^thPercentile	50%
Target	50^thPercentile	100%
Maximum	75^thPercentile and above	200%

Interpolation would be used to determine payout levels in between thresholds. To achieve a threshold payout, TSR must rank at or above the 25th percentile. The payout value was limited to six times the target grant value and was capped at 100% of target if absolute TSR was negative for the performance period. The PSUs accrued dividend equivalents during the performance period, which were paid at the time the PSUs vested and common stock was issued.

The Livent Committee viewed the inclusion of a metric that includes TSR as critical because it tied executive officer compensation with the creation of shareholder value and aligned the interests of executive officers with those of Livent and its shareholders. By measuring Livent’s performance relative to peers, it mitigated the impact of macroeconomic factors, both positive and negative, that affect the industry and/or stock price performance and are beyond the control of management. Additionally, it provided rewards that were more directly aligned with performance through different economic cycles.

In determining the number of options awarded to meet the compensation level approved for an NEO, the portion of the award value related to stock options was divided by the Black-Scholes value on the date of grant.

The exercise price of all stock option awards to NEOs was equal to the closing price of Livent’s stock on the date of the grant. The stock options have three-year cliff vesting.

In determining the amount of RSUs awarded to meet the compensation level approved for an NEO, the portion of the award value related to restricted stock units was divided by the closing stock price on the date of grant.

The RSUs have three-year cliff vesting.

During the vesting period, if cash dividends were paid to Livent’s stockholders, the NEOs generally received a special cash payment equal to the amount he or she would have received had he or she been the record holder of the shares underlying the RSUs when the dividend was declared and paid.

Compensation Awarded and Equity Treatment In Connection With Livent’s Merger With Allkem to Form Arcadium Lithium

Treatment of Outstanding Equity

Upon the completion of the merger on January 4, 2024, outstanding Livent equity awards held by Livent NEOs were treated as follows:

•	Stock options were assumed by the Company and converted to equivalent awards with respect to Company stock and remain subject to the same terms and conditions.

•	Time-based RSUs were assumed by the Company, with a pro rata portion vesting in Company shares following such assumption, and with the unvested portion converted to equivalent awards with respect to Company stock and remaining subject to the same terms and conditions.

•	PSUs vested fully at target. The vesting of the PSUs was accelerated from January 4, 2024, the closing of the merger, to December 22, 2023.

Transaction Bonus Program

On October 12, 2023, the Livent Committee approved a transaction bonus program for select Livent employees to recognize their significant efforts in bringing the merger to fruition, subject to continued employment through the completion of the merger with Allkem. Under the transaction bonus program and in connection with the closing of the merger, Mr. Graves received a cash transaction bonus of $500,000 and Mr. Antoniazzi and Ms. Ponessa each received a transaction bonus of $200,000. These bonuses were paid to the NEOs in December 2023.

Retention Bonuses

On July 18, 2023, the Livent Committee approved a retention program for select Livent employees. Pursuant to the retention program, each of Mr. Antoniazzi and Ms. Ponessa received a retention bonus of $250,000, payable on the 12-month anniversary of the completion of the merger (i.e., January 4, 2025), subject to his or her continued employment through the payment date. In the event that Mr. Antoniazzi or Ms. Ponessa voluntarily resigns for any reason, including for “good reason,” or if he or she is terminated for unsatisfactory job performance or misconduct, the retention bonus will be forfeited in its entirety. If his or her employment is terminated without “cause” prior to the payment date, he or she will remain entitled to receive the retention bonus payment, contingent on the executive’s execution of a release of claims in favor of the company. Mr. Graves did not receive any retention bonus under the retention program.

Post-Employment Compensation

Qualified and Non-Qualified Defined Contribution Plans

Livent offered a tax-qualified 401(k) defined contribution plan (the “Qualified Savings Plan”) covering substantially all Livent U.S. employees, including the NEOs. Eligible employees were permitted to make voluntary pre-tax and post-tax contributions to the Qualified Savings Plan and were eligible for matching company contributions. The Qualified Savings Plan also permitted discretionary company contributions. All contributions to the Livent Qualified Savings Plan were subject to certain limitations under the Internal Revenue Code.

Livent also offered a non-qualified deferred compensation plan (the “Nonqualified Savings Plan”) that was available to certain highly compensated individuals, including the NEOs. The Nonqualified Savings Plan was designed to mirror the Qualified Savings Plan, but without application of the Internal Revenue Code limits. Livent’s matching contribution under both plans was 80% of the amount deferred up to a maximum of 5% of eligible earnings (i.e., base salary and annual incentive paid in a calendar year). However, the matching contribution under both plans could not exceed 4% of an NEO’s total eligible earnings. Livent’s non-elective employer contributions under both plans (the “core contribution”) was 5% of an employee’s eligible earnings. However, Mr. Antoniazzi was eligible for an enhanced core contribution of 15% of his eligible earnings based on his prior participation in a FMC predecessor plan (as described below). An employee must have been employed as of the last day of the plan year (i.e., December 31st) to have received the core contribution.

Pension Benefits

Livent did not maintain a qualified or non-qualified defined benefit pension plan. However, prior to Livent’s separation from FMC, Mr. Antoniazzi earned pension benefits as a participant in the FMC Retirement Salaried and Non-Union Hourly Employees’ Retirement Plan and the FMC Salaried Employees’ Equivalent Plan (collectively, the “FMC Pension Plans”). Mr. Antoniazzi ceased earning any additional benefits under the FMC Pension Plans effective December 31, 2018. To compensate for the pension benefits that otherwise would have been earned under the FMC Pension Plans, Mr. Antoniazzi will be eligible for special “short-fall” contributions under Livent’s Nonqualified Savings Plan. Subject to continuing employment, Mr. Antoniazzi receives an annual contribution of $68,000 to his Nonqualified Savings Plan account beginning in 2022 and continuing through 2029.

Severance Arrangements

Livent maintained Executive Severance Guidelines (the “Severance Guidelines”), which provided for the payment of severance pay and benefits in the event of an executive’s termination of employment without cause (other than in connection with a change in control of Livent or as a result of death, disability or normal retirement). No Livent NEO had a contractual entitlement to any severance pay or benefits under the Severance Guidelines, and the Livent Committee had discretion to enhance or reduce the severance pay or benefits under the Severance Guidelines in any specific case. As a condition to receiving any severance pay or benefits under the Severance Guidelines, the NEO was required to execute a release of claims in favor of Livent, as well as a non-solicitation, non-competition and confidentiality agreement.

See “Potential Payments upon Termination or Change in Control,” which describes the payments to which the participating NEOs were entitled under the Livent Severance Guidelines.

Change in Control Arrangements

The Livent Committee believed that the long-term interests of Livent stockholders were best served by providing reasonable income protection for NEOs to address potential change in control situations in which they may otherwise be distracted by their potential loss of employment in the event of a successful transaction. Livent entered into an executive severance agreement with each NEO that provided certain financial benefits in the event of a change in control. These were “double trigger” arrangements – i.e., severance benefits under these arrangements are only triggered by a qualifying event that also resulted in the executive’s termination of employment under certain specified circumstances within 24 months following the event.

In addition, under the terms of Livent’s equity awards, if a change in control occurred and those awards were not assumed or continued by the successor or surviving corporation, or if the holder experienced a qualifying termination of employment within 24 months of a change in control, the unvested portion of any outstanding awards generally vested and became exercisable, as applicable.

See “Potential Payments upon Termination or Change in Control,” below for further information.

TABLE OF CONTENTS

Health and Welfare Benefits

Livent offered broad-based medical, dental, vision, life, and disability plans to all employees.

Perquisites and other Personal Benefits

Livent did not generally provide executive officers, including the NEOs, with perquisites or other personal benefits, except for financial and tax advisory services for the CEO, CFO and General Counsel, reserved parking, annual executive physicals, and, in the case of the CEO, a club membership. The perquisites and personal benefits summarized above were provided because Livent believed that they supported executive officers, served a necessary business purpose, and the related amounts of compensation were not material to the overall executive compensation program. In order to govern the provision of these perquisites, Livent had established an executive perquisite policy. The methodology for setting maximum perquisite levels was driven primarily by competitive practice, business necessity and financial considerations of Livent. The costs of these items are reported in the Summary Compensation Table.

We do not provide excise tax “gross-ups” to any executive officers.

V. ADDITIONAL COMPENSATION POLICIES AND PRACTICES

Clawback Policy

In 2023, Livent adopted its Financial Restatement Clawback Policy to enable Livent to recover erroneously awarded

incentive-based compensation in the event that Livent was required to prepare an accounting restatement. The policy was designed to comply with, and to be interpreted in a manner consistent with, Section 10D of the Exchange Act, SEC Rule 10D-1, and with the NYSE listing rules. Under the policy, in the event of an accounting restatement due to Livent’s material noncompliance with any financial reporting requirement under the securities laws, including any required accounting restatement to correct a material error in previously issued financial statements, or that would result in a material misstatement if the error were corrected in the current period or left uncorrected in the current period, Livent had to recover erroneously awarded incentive-based compensation previously paid to the Livent’s executive officers in accordance with the terms of such clawback policy. Furthermore, under the policy, Livent was prohibited from indemnifying any executive officer or former executive officer against the loss of erroneously awarded incentive-based compensation and from paying or reimbursing an executive officer for purchasing insurance to cover any such loss.

In addition, there was a clawback provision in Livent’s equity plan that allows for clawback in the event of serious misconduct by a participant.

Executive Stock Ownership Guidelines

The Livent Committee believed that Livent and its stockholders were best served when executive officers managed the business with a long-term perspective. As such, Livent implemented executive stock ownership guidelines in February 2021, as Livent believed stock ownership was an important tool to strengthen the alignment of interests among executive officers and stockholders, to reinforce executive officers’ commitment to Livent and to demonstrate Livent’s commitment to sound corporate governance. Livent’s NEOs had five years from the date the guidelines were adopted to comply with the ownership guidelines. Any newly hired or promoted executives had five years from the date of their hire or appointment to comply with the guidelines. After the initial five-year phase-in period, compliance with the ownership guideline was measured on December 31 of each year.

	Position			Multiple of Base Salary
	Chief Executive Officer			5x
	Chief Financial Officer and General Counsel			2x

For this purpose, RSUs (whether or not vested), stock held in the Livent Nonqualified Savings Plan and stock owned directly or beneficially owned by the executive or the executive’s immediate family members, counted. Unexercised stock options, including vested in-the-money options, and PSUs that are unearned (i.e., performance-based awards for which the applicable performance conditions have not been satisfied) were not counted for purposes of compliance.

TABLE OF CONTENTS

Anti-Hedging and Anti-Pledging Policy

Livent’s insider trading policy prohibited employees (including officers) and directors from engaging in any hedging transactions (including transactions involving options, puts, calls, prepaid variable forward contracts, equity swaps, collars and exchange funds or other derivatives) that were designed to hedge or speculate on any change in the market value of Livent’s equity securities. It also explicitly prohibited employees (including officers) and directors from effecting short sales of Livent’s equity securities, which were inherently speculative in nature and contrary to the best interests of Livent and its stockholders. Livent’s insider trading policy also prohibited employees (including officers) and directors from pledging Livent’s securities in any circumstance, including by purchasing Livent securities on margin or holding Livent’s securities in a margin account.

Tax Deductibility of Executive Compensation

Generally, a public company cannot deduct compensation in excess of $1 million paid in any year to a company’s chief executive officer, chief financial officer and the three other most highly compensated officers.

The Summary Compensation Table lists compensation for Livent’s Chief Executive Officer, Chief Financial Officer, and Livent’s other most highly compensated executive officer who served as of the end of the fiscal year. Livent had no other executive officers during 2023. The material terms of the pay elements included in the Summary Compensation Table are described above in the CD&A.

1.	The amounts shown in this column represent discretionary transaction bonus awards paid to each of the NEOs in December 2023 in connection with their efforts in closing of the merger with Allkem.

The amounts shown in the Stock Awards column include the aggregate grant date fair value of the RSUs and PSUs, computed in accordance with FASB Accounting Standards Codification Topic 718 (“Topic 718”), excluding the effect of estimated forfeitures. Amounts shown in this column relating to RSUs reflect the market value of the RSUs using the closing price of a share of Livent’s Common Stock as reported on the NYSE on the date of grant, multiplied by the number of shares underlying each award. Amounts shown in this column relating to PSUs were determined using a Monte Carlo simulation model. The grant date fair value of the PSUs included above is determined based upon achievement of performance at the “target” level, which was the probable outcome of the performance metrics associated with each award of PSUs as of the grant date. If performance for the PSUs were to be achieved at the “maximum” level, the grant date fair value of the PSUs for the NEOs would have been as follows: Mr. Graves: $1,100,010, Mr. Antoniazzi: $275,014, and Ms. Ponessa: $225,018. For information regarding assumptions, factors and methodologies used in the computations pursuant to Topic 718, see Note 12 to the consolidated financial statements in the Annual Report on Form 10-K for the year ending December 31, 2023. Additionally, the amounts in the Stock Awards column include the aggregate incremental fair value of the outstanding PSUs granted in 2022 and 2023, the vesting of which was accelerated at the target level in December 2023 in connection with the merger with Allkem.

The amounts shown in the Option Awards column represent the aggregate grant date fair value of stock options computed in accordance with Topic 718. Valuations of options were determined using the Black-Scholes option pricing model. For information regarding assumptions, factors and methodologies used in the computations pursuant to Topic 718, see Note 12 to the consolidated financial statements in the Annual Report on Form 10-K for the year ending December 31, 2023.

The actual amount of the Annual Incentive paid to each NEO with respect to 2023 is stated in the “Non-Equity Incentive Plan Compensation” column of the Summary Compensation Table. The threshold, target and maximum performance signify performance that will yield a rating of 0, 1.0 and 2.0, respectively. In order for any payout to be earned, performance must exceed the threshold level. With respect to the Adjusted EBITDA metric, the amount paid for performance falling between the threshold and target achievement levels and the target and maximum achievement levels is determined using straight-line interpolation.

Amounts disclosed in these columns reflect the threshold, target and maximum number of PSUs that may be earned with respect to the PSUs granted to Livent’s NEOs in 2023. The PSUs would vest based on Livent’s Relative TSR Percentile Ranking over the three-year performance period from January 1, 2023 to December 31, 2025. See “Compensation Program Components—Long-Term Incentives” for a more detailed description of these PSUs.

3.	Amounts disclosed in this column reflect the number of RSUs granted to Livent’s NEOs in 2023. The RSUs vest in full on the third anniversary of the grant date, subject to continued service.

4.	Amounts disclosed in this column reflect the number of stock options granted to Livent’s NEOs in 2023. The options vest in full on the third anniversary of the grant date, subject to continued service.

The amounts shown for PSUs represent the aggregate grant date fair value of the PSUs, computed in accordance with Topic 718, excluding the effect of estimated forfeitures and assuming target performance. Amounts disclosed for these PSUs were determined using a Monte Carlo simulation valuation model. For information regarding assumptions, factors and methodologies used in the computations pursuant to Topic 718, see Note 12 to the consolidated financial statements in the Annual Report on Form 10-K for the year ending December 31, 2023.

The amounts listed in this column are reported as compensation in the “All Other Compensation” column of the Summary Compensation Table 2023. In addition to the employer matching contribution of $103,772, Mr. Graves received nonqualified non-elective contributions of 5% of compensation on his eligible earnings amount, which was $129,715. In addition to the employer matching contribution of $30,626, Mr. Antoniazzi received a nonqualified non-elective employer contribution of 15% of compensation on his eligible earnings amount, which was $134,050, and a supplemental employer contribution of $68,000 related to Mr. Antoniazzi relinquishing FMC pension plan benefits when moving to Livent. Ms. Ponessa received an employer matching contribution of $23,984. Ms. Ponessa also received nonqualified non-elective contributions of 5% of compensation on her eligible earnings amount, which was $29,980.

Amounts listed in this column for Mr. Graves include an aggregate of $1,534,128 which was reported in previous years in Livent’s Summary Compensation Table or, during Mr. Graves’ prior tenure as a named executive officer at FMC, in FMC’s Summary Compensation Table. The amounts listed for Mr. Antoniazzi and Ms. Ponessa include an aggregate of $485,693 and $280,028 respectively, which were reported in Livent’s Summary Compensation Table in previous years.

Livent’s Nonqualified Savings Plan was a deferred compensation plan that provided for employee contributions as well as Livent matching, non-elective and discretionary contributions. The Nonqualified Savings Plan worked in tandem with Livent’s Qualified Savings Plan. Please see the “Compensation Program Components—Post-Employment Compensation” section above for a description of such plans.

Employee and employer contributions to the Nonqualified Savings Plan were deemed invested by the employee in his or her choice of more than 20 investment alternatives. All investments, except for the FMC Stock Fund and Livent Stock Fund, were mutual funds, and all

Arcadium Lithium plc 54 2024 Proxy Statement

TABLE OF CONTENTS

investments could be exchanged by the employee at any time. Earnings on investments were market earnings. There were no programs or provisions for guaranteed rates of return. Distributions under Livent’s Nonqualified Savings Plan had to occur or commence at the earlier of separation of service plus six months or at a designated time elected by the employee at the time of deferral. Distributions may be in a lump sum or installments as determined by the employee’s distribution election.

Livent’s Nonqualified Savings Plan was subject to certain disclosure and procedural requirements of the Employee Retirement Income Security Act of 1974 (“ERISA”), but as a “top hat” plan was not subject to the eligibility, vesting, accrual, funding and fiduciary responsibility requirements of ERISA. The Nonqualified Savings Plan represented an unfunded liability and all amounts listed in the table above were unsecured and therefore not guaranteed to be fully paid in the event of Livent’s insolvency or bankruptcy.

Mr. Graves’ and Ms. Ponessa’s balances in Livent’s Nonqualified Savings Plan include amounts the NEOs transferred into the plan from a legacy FMC nonqualified plan.

PAY RATIO DISCLOSURE

We disclose here the Livent CEO to median employee pay ratio as calculated in accordance with Item 402(u) of Regulation S-K. In order to identify a median employee, we examined the total cash compensation for all Livent employees, excluding the CEO and certain non-U.S. based employees as described below, who were employed by Livent on November 1, 2023. We included all Livent employees, whether employed on a full-time, part-time, or temporary basis. We annualized the compensation for any non-temporary Livent employee who was not employed by Livent for the full year in 2023. For non-U.S. employees, we converted their total cash compensation to U.S. Dollars based on a published average annual exchange rate as of November 1, 2023. We excluded less than 5% of our non-U.S. based employees as follows: Australia (1), South Korea (2), Canada (3), Japan (3), and Singapore (23). After excluding the Livent CEO and these non-U.S. based employees, Livent had 398 U.S.-based employees and 738 non-U.S. based employees, and irrespective of these exclusions, Livent had 398 U.S.-based employees and 770 non-U.S. based employees as of November 1, 2023. Due to anomalous compensation characteristics of the employee originally identified using such methodology, we substituted such employee with an employee with substantially similar compensation, whose compensation was viewed as more representative of the Livent median employee.

We calculated annual total compensation for the Livent median employee using the same methodology we use for Livent’s named executive officers as set forth in the 2023 Summary Compensation Table in this proxy statement. Using this methodology, we have estimated that the median employee’s annual total compensation was $74,929, and the annual total compensation of the CEO was $5,070,011. Therefore, the 2023 Livent CEO to median employee pay ratio is 68:1.

POTENTIAL PAYMENTS UPON TERMINATION OR CHANGE IN CONTROL

Although Livent did not maintain individual employment agreements with any NEO that provide guaranteed payments in the event of a termination of employment, upon such a termination, or upon a change in control of Livent, Livent maintained certain arrangements, guidelines, plans and programs pursuant to which Livent’s NEOs could be eligible to receive certain cash severance, equity vesting and other benefits.

The amounts that Livent’s NEOs could receive are set forth below for the following types of termination of employment:

•	Termination without cause not in connection with a change in control;

•	Termination without cause or by executive for good reason following a change in control;

•	Death or disability;

•	Retirement; and

•	Termination for cause.

In accordance with SEC rules, we have used certain assumptions in determining the amounts shown and the narrative below. We have assumed that the termination of employment or change in control occurred on December 31, 2023. On that date, the closing price on the NYSE of a Livent share was $17.98. Since many factors (e.g., the time of year when the event occurs, Livent’s stock price and the executive’s age) could affect the nature and amount of benefits a Livent NEO could potentially receive, any amounts

Arcadium Lithium plc 55 2024 Proxy Statement

TABLE OF CONTENTS

paid or distributed upon a future termination may be different from those shown in the tables below. Under these SEC rules, the potential payments upon termination or change in control do not include certain distributions to the NEO or benefits to which the NEO is already entitled, including the value of equity awards that have already vested and distributions from qualified retirement plans.

Termination without Cause (Not Involving a Change in Control)

Cash and Other Amounts

Livent maintained Severance Guidelines, which provided non-mandatory guidance for the payment of severance pay and benefits in the event of an executive’s termination of employment by Livent without cause (other than in connection with a change in control of Livent or as a result of death, disability or normal retirement). No Livent NEO had a contractual entitlement to any severance pay or benefits under the Severance Guidelines, and the Livent Committee had the discretion to enhance or reduce the severance pay or benefits under the Severance Guidelines in any specific case. As a condition to receiving any severance pay or benefits under the Severance Guidelines, the NEO had to execute a release of claims in favor of Livent, as well as a non-solicitation, non-competition and confidentiality agreement. The Severance Guidelines provided for delivery to the NEO of the following:

•	An amount equal to 12 months of the NEO’s base salary, payable in a lump sum;

•	An amount equal to 12 months of the NEO’s target annual incentive award, payable in a lump sum;

•	A pro-rated annual incentive award (at target) for the year of termination;

•	Transition benefits (e.g., outplacement assistance up to $20,000, and financial/tax planning for the last calendar year of employment); and

•	Continuation of health benefits for the one-year period following the date of termination.

In addition, as noted above under “Compensation Program Components—Compensation Awarded and Equity Treatment in Connection with Livent’s Merger with Allkem to Form Arcadium Lithium,” pursuant to the terms of their retention bonus agreements, Mr. Antoniazzi and Ms. Ponessa are entitled to payment of their retention bonuses upon a termination without cause, whether prior to or following a change in control.

Equity Awards

In the event that an NEO’s employment by Livent had been terminated without cause on December 31, 2023, the NEO’s outstanding equity incentive awards would have been treated as follows, contingent on the NEO’s execution of a release of claims and, in the case of benefits provided under the Guidelines, execution of a non-compete, non-disclosure and non-solicitation agreement:

Options

Under the Guidelines:

•	Vested stock options would have remained exercisable for twelve months; and

•	Outstanding and unvested stock options that would have vested within one calendar year following the termination date would have become exercisable on their regularly scheduled vesting dates, and remained exercisable for one year thereafter.

•	Outstanding and unvested stock options granted in 2022 and 2023 would be cancelled as of such termination.

Restricted Stock Units

Under the terms of the RSU award agreements and the Guidelines:

•	Outstanding and unvested RSUs would have vested on a pro rata basis based on the number of days the NEO was employed during the vesting period.

Arcadium Lithium plc 56 2024 Proxy Statement

TABLE OF CONTENTS

Performance-Based Restricted Stock Units

Under the Guidelines:

•	Outstanding and unvested PSUs would be earned based on actual performance through the end of the applicable performance period, pro rata to reflect the number of days worked during the performance period.

Termination without Cause or by Executive for Good Reason Following a Change in Control CONTROL

Cash and Other Amounts

Each of Livent’s NEOs entered into an Executive Severance Agreement, effective as of Livent’s IPO and as amended as of February 23, 2021, which generally provided that, in the event such individual’s employment was terminated by Livent without “cause” or by such individual for “good reason” in each case, within the 24-month period following a “change in control” of Livent (referred to in the tables that follow as a “Change in Control Termination”), then such individual would be entitled, contingent on the executive’s execution of a release of claims in favor of Livent and its affiliates, to the payments and benefits detailed below.

•	An amount equal to three times (in the case of Messrs. Graves and Antoniazzi) and two times (in the case of Ms. Ponessa) the base salary, payable in a lump sum;

•	An amount equal to three times (in the case of Messrs. Graves and Antoniazzi) and two times (in the case of Ms. Ponessa) the target annual incentive award, payable in a lump sum;

•	A pro-rated annual incentive award for the year of termination;

•	Reimbursement for outplacement services for a two-year period following the termination date, with the total reimbursements capped at 15% of base salary as of the termination date;

•

Continuation of medical and welfare benefits (including life and accidental death and dismemberment and disability insurance coverage) for such individual (and covered spouse and dependents), at the same premium cost and coverage level as in effect as of the change in control date, for three years (in the case of Messrs. Graves and Antoniazzi) and two years (in the case of Ms. Ponessa) following the date of termination (or, if earlier, the date on which substantially similar benefits at a comparable cost are available from a subsequent employer) or, if such benefits continuation is not permissible under the applicable plan or would result in adverse tax consequences, cash benefits in lieu thereof under the updated Executive Severance Agreements; and

•

Continuation of retirement benefits for three years (in the case of Messrs. Graves and Antoniazzi) and two years (in case of Ms. Ponessa) following the date of termination of the annual Livent contribution made on the NEO’s behalf to the Livent’s qualified retirement plan and the Livent’s nonqualified retirement plan as in effect immediately prior to the date of the change in control (excluding any pre-tax or post-tax contribution authorized by an NEO).

The Livent Executive Severance Agreements provided that if the amounts to be received in connection with a change in control would trigger the excise tax on parachute payments, either the payments would be lowered so as not to trigger the excise tax, or they would be paid in full subject to the tax, whichever produces the better net after-tax position.

Equity Awards

To the extent that the successor of the surviving entity (or its parent) of Livent had continued or assumed equity awards upon the change in control, but the NEO’s employment was terminated without cause or the NEO resigned for good reason within the 24 months following the change in control all outstanding and unvested stock options and RSUs would have vested and all outstanding and unvested PSUs would have vested at the greater of target or actual performance as of the date of the change in control, subjected to execution of a release of claims.

To the extent that a change in control had occurred on December 31, 2023, and the successor or the surviving entity (or its parent) had failed to continue or assume equity awards, then under the terms of those awards, all outstanding and unvested stock options and RSUs would have vested on the change in control and all outstanding and unvested PSUs would have vested at the greater of target or actual performance as of the change in control.

Arcadium Lithium plc 57 2024 Proxy Statement

TABLE OF CONTENTS

As discussed above in the CD&A section of this proxy statement, the vesting of the outstanding performance-based restricted stock units held by each NEO was accelerated on December 22, 2023 in connection with merger with Allkem, and vested at the target level of performance.

Generally, the following definitions apply to Livent’s equity grants:

•

A “Change in Control” is generally the acquisition of 20% or more of Livent’s Common Stock; a substantial change in the composition of Livent’s Board such that the current Board no longer constitutes a majority; a merger, sale of substantially all of the assets or acquisition, unless the beneficial owners prior to the transaction own more than 60% of the resulting corporation.

•	“Cause” generally means a wilful and continued failure to substantially perform the executive’s material employment duties, wilful and deliberate conduct which is materially injurious to Livent, or having been convicted to a felony on or prior to the Change in Control.

•

“Good Reason” generally means the assignment of duties materially inconsistent with the executive’s duties and status as an employee or reduction in the nature of the duties, Livent requiring the executive to be based at a location which is at least 50 miles further from the office where the executive is located at the time of the Change in Control, or a reduction in base salary, each of which Livent had failed to cure after receiving notice from the Named Executive Officer.

Death or Disability

In the event of a termination of a Livent’s NEO’s employment due to death or disability, the NEO would not be entitled to severance pay or benefits, and outstanding equity incentive awards would have been treated as follows:

•	All outstanding and unvested stock options would fully vest and become exercisable, and would remain exercisable for up to five years following the date of termination;

•	All outstanding and unvested RSUs would fully vest;

•	If an NEO’s employment terminates due to his or her disability, all outstanding and unvested PSUs would be earned based on actual performance through the end of the applicable performance period as if the NEO had remained in service; and

•	If an NEO’s employment terminates due to his or her death, all outstanding and unvested PSUs would be earned at target as of the date of the NEO’s death.

Retirement

The equity awards granted in 2021 and 2022 to Livent NEOs did not contain retirement vesting provisions, nor did Livent’s equity plan.

Cause

In the event of a termination of an NEO’s employment for cause, all outstanding and unvested equity awards will be cancelled, and all vested stock option awards will expire immediately.

*	Amounts shown generally reflect the amounts specified in the Severance Guidelines, which are not contractually guaranteed.

1.	On December 31, 2023, Messrs. Graves and Antoniazzi and Ms. Velazquez-Ponessa were not eligible to retire.

2.	The amount shown is equal to three times (two times for Ms. Ponessa) the sum of base salary plus target annual incentive, calculated by using the highest annualized base salary and target annual incentive available to the NEO during his/her career with the Company.

3.	The amount shown is equal to the sum of 12 months of base salary plus target annual incentive

4.	The amount shown is the pro rata amount of any annual incentive award payable in the year of separation. This is the same annual incentive amount reported in the Summary Compensation Table because the table assumes termination would have occurred on the last day of the fiscal year.

5.	The amount shown is the prorated target bonus for the year of termination based on the Severance Guidelines.

All unvested stock options vest upon the change in control, even if the NEO was not terminated, if the surviving entity fails to continue or assume the award. The amount shown is the value of all unvested stock options based upon the difference between the exercise price and the stock price of $17.98 at December 29, 2023. Please note, however, that the ultimate value of the foregoing options will depend on the stock price on the date of exercise.

The Severance Guidelines provide that all options that would have vested within one year following termination will become exercisable on their regularly scheduled dates. As noted above, the Severance Guidelines are not binding on the Company and are intended to serve merely as guidelines, with the Livent Committee retaining the ultimate discretion to modify the Severance Guidelines for any specific termination. The amount shown is the value of all unvested stock options based on the difference between the exercise price and the stock price of $17.98 at December 29, 2023. Please note, however, that the ultimate value of the foregoing options will depend on the stock price on the date of exercise.

8.	All unvested RSUs vest upon the change in control, even if the NEO was not terminated, if the surviving entity fails to continue or assume the award. The amount shown is the market value of all unvested RSUs based on the stock price of $17.98 at December 29, 2023.

9.	Unvested RSUs will vest pro rata, with such pro ration calculated as described on page 55.

10.	The amount shown is equal to three times (two times for Ms. Ponessa) the sum of the annual Company contributions made on the Executive’s behalf to the Livent Savings and Investment Plan and the Livent Nonqualified Savings Plan.

11.	Welfare benefits of health care and dental, life insurance and disability insurance continue for three years (two years for Ms. Ponessa). The amounts shown are the estimated cost to the Company for such benefits during the period.

12.	Welfare benefits of health care and dental insurance continue for one year. The amounts shown are the estimated cost to the Company for such benefits during the period.

13.

The executives are entitled to outplacement services, which are capped at 15% of the NEO’s base salary. The actual amounts paid in respect of such services will be determined based upon the outplacement services obtained, if any, by an NEO upon termination. However, the amounts reflected in the table represent the maximum amounts that could be paid by the Company in respect of these services.

14.

The executives are entitled to outplacement services up to $20,000, plus financial and tax planning services for the last calendar year of employment. Executives generally receive an allowance for financial planning and tax benefits, which are not shown in the table because they would have already been used by an executive terminated on December 31, 2023.

15.	The executives are entitled to a retention bonus if employed by the Company 12 months after the closing date of the transaction or if terminated by the Company without cause prior to the payment.

16.

The NEO severance agreements provide that, if the amounts to be received upon a change in control would trigger the excise tax on parachute payments, either the payments will be lowered so as not to trigger the excise tax, or they will be paid in full subject to the tax, whichever produces the better net after-tax position. The benefits of Mr. Antoniazzi exceeded the triggering amount, and forfeiture of benefits resulted in a better after-tax situation than the receipt of full benefits with payment of the excise tax. Therefore, we have shown amounts that he would have forfeited upon a theoretical termination of employment on December 31, 2023 in the table. The amount shown does not take into account any possible reductions related to “reasonable compensation” for services before and/or after the change in control date.

1.	Paul Graves was Livent’s PEO for each year presented. The individuals comprising Livent’s Non-PEO NEOs for each year presented are Gilberto Antoniazzi and Sara Ponessa.

The amounts shown for Compensation Actually Paid have been calculated in accordance with Item 402(v) of Regulation S-K and do not reflect compensation actually earned, realized, or received by the Company’s NEOs, who were the sole executive officers at Livent. These amounts reflect the Summary Compensation Table Total with certain adjustments as described in footnote 3 below.

Compensation Actually Paid reflects the exclusions and inclusions of certain amounts for the Livent PEO and Non-PEO NEOs as set forth below. Equity values are calculated in accordance with FASB ASC Topic 718. Amounts in the Exclusion of Stock Awards and Option Awards column are the totals from the Stock Awards and Option Awards columns set forth in the Summary Compensation Table.

The TSR set forth in this table assumes $100 was invested on December 31, 2019, in Livent’s Common Stock, through the end of the listed year. The Peer Group TSR set forth in this table utilizes the S&P 500 Chemicals Index, which we also utilize in the stock performance graph required by Item 201(e) of Regulation S-K included in our Annual Report for the year ended December 31, 2023. The Peer Group TSR assumes $100 was invested for the period starting December 31, 2019, through the end of the listed year in the S&P 500 Chemicals Index. Historical stock performance is not necessarily indicative of future stock performance.

5.	This column includes Livent’s Net Income for each year presented.

We determined Livent Adjusted EBITDA, as defined for purposes of our annual incentive plan and discussed in our CD&A, to be the most important financial performance measure used to link Livent performance to Compensation Actually Paid to Livent’s PEO and Non-PEO NEOs in 2023. This performance measure may not have been the most important Livent financial performance measure for prior years, and we may determine a different financial performance measure to be the most important financial performance measure in future years, including for purposes of the combined company. Livent’s Adjusted EBITDA is defined for purposes of the annual incentive plan as set forth above in the “Executive Compensation—Compensation Discussion and Analysis” section.

Relationship Between Compensation Actually Paid and Company TSR

The following chart sets forth the relationship between Compensation Actually Paid to Livent’s PEO, the average of Compensation Actually Paid to Livent’s Non-PEO NEOs, and Livent’s cumulative TSR over the four most recently completed fiscal years to that of the S&P 500 Chemicals Index over the same period.

NOTICE AND ACCESS

As permitted by the SEC, we are furnishing to shareholders our Notice of the Annual Meeting, this Proxy Statement and our Annual Report primarily over the internet. On or about June 7, 2024, we will mail to each of our shareholders (other than those who previously requested electronic delivery or previously elected to receive delivery of a paper copy of the proxy materials) a Notice of Internet Availability of Proxy Materials (the “Notice of Internet Availability”) containing instructions on how to access and review the proxy materials via the internet and how to submit a proxy electronically using the internet.

The Notice of Internet Availability also contains instructions on how to receive, free of charge, paper copies of the proxy materials. If you received the Notice of Internet Availability, you will not receive a paper copy of the proxy materials unless you request one.

We believe the delivery options that we have chosen will allow us to provide our shareholders with the proxy materials they need, while minimizing the cost of the delivery of the materials and the environmental impact of printing and mailing paper copies.

HOUSEHOLDING

We have adopted a procedure approved by the SEC called “householding.” Under this procedure, we are permitted to deliver a single copy of the Notice of Internet Availability and, if a shareholder requested printed versions by mail, our proxy materials, including this proxy statement and our annual report, to shareholders sharing the same address who did not otherwise notify us of their desire to receive multiple copies of our proxy materials. Householding allows us to reduce our printing and postage costs and limits the volume of duplicative information received at your household. A separate proxy card will continue to be mailed for each registered shareholder account who requests a paper copy of the proxy materials.

We will promptly deliver, upon oral or written request, a separate copy of the Notice of Internet Availability and, if a shareholder requested printed versions by mail, the proxy materials to any shareholder residing at an address to which only one copy was mailed. If you wish to receive an additional copy of the Notice of Internet Availability or our proxy materials, or if you received multiple copies and wish to request householding in the future, you may make such request by writing to our Corporate Secretary at Arcadium Lithium plc, 1818 Market Street, Suite 2550, Philadelphia, PA 19103.

If you are a street name holder and wish to revoke your consent to householding and receive separate copies of our proxy materials for the annual meeting of shareholders this year or future years, you may call Broadridge Investor Communications Services toll-free at (866) 540-7095 or write to them c/o Householding Department, 51 Mercedes Way, Edgewood, New York 11717.
