GENERAL INFORMATION
What is the deadline for voting my shares if I do not vote in person at the Annual General Meeting?
If you are a shareholder of record, you may vote by internet or by telephone until 11:59 p.m., United States Eastern Time, on May 8, 2024, or by mail by returning a signed instrument of proxy (or proxy card) to Mallinckrodt plc, c/o Broadridge,

Shareholder of Record.   The holders whose names appear in the Register of Members of Mallinckrodt, are considered the shareholder of record of those shares.
Beneficial Owner of Shares Held in “Street Name.”   Holders of shares held in an account at a bank, brokerage firm or other similar organization, are ordinarily considered the beneficial owner of shares held in “street name.” As we are not aware
of any such arrangements with respect to our ordinary shares, this Proxy Statement does not generally address such beneficial ownership.

Yes. You have the right to revoke your proxy before it is voted at the Annual General Meeting. You may vote again on a later date within the proxy voting deadlines described above by internet or by telephone (only your latest proxy submitted prior to the meeting will be counted) or by signing and returning a new proxy card with a later date, or by attending the meeting and voting in person.
However, your attendance at the Annual General Meeting will not automatically revoke a previously submitted proxy unless you actually vote in person at the meeting or file a written instrument with our Corporate Secretary prior to the start of the meeting requesting that your prior proxy be revoked.
What happens if I do not give specific voting instructions when I deliver my proxy?
If you are a shareholder of record as of the record date and you:

indicate when voting by internet or by telephone that you wish to vote as recommended by our Board, or

sign and return a proxy card without giving specific voting instructions,
then the Company-designated proxy holders will vote your shares in the manner recommended by our Board on all matters presented in this Proxy Statement and as the proxy holders may determine in their discretion regarding any other matters properly presented for a vote at the meeting.
What is the “quorum” requirement for the Annual General Meeting?
In order to conduct any business at the Annual General Meeting, holders of a majority of our ordinary shares outstanding and entitled to vote on the record date must be present in person or represented by valid proxies. This is called a quorum. Your shares will be counted for purposes
of determining if there is a quorum, whether representing votes for, against or abstained if you:

are present and vote in person at the meeting;

have voted by internet or by telephone; or

have submitted a proxy card by mail.

What is the difference between holding shares as a shareholder of record and as a beneficial owner of shares held in street name?
Shareholder of Record.   If you hold ordinary shares and your name appears in the Register of Members of Mallinckrodt, you are considered the shareholder of record of those shares.
Beneficial Owner of Shares Held in Street Name. If your ordinary shares are held in an account
at a bank, brokerage firm or other similar organization, then you are the beneficial owner of shares held in “street name.” As a beneficial owner, you have the right to direct your bank or brokerage firm how to vote the shares held in your account.
Can I change my vote after I have submitted my proxy?
Yes. You have the right to revoke your proxy before it is voted at the Annual General Meeting. You may vote again on a later date within the proxy voting deadlines described above by internet or by telephone (only your latest proxy submitted prior to the meeting will be counted) or by signing and returning a new proxy card with a later date, or by attending the meeting and voting in person.

What happens if I do not give specific voting instructions when I deliver my proxy?
Shareholders of Record.   If you are a shareholder of record and you:

indicate when voting by internet or by telephone that you wish to vote as recommended by our Board; or

sign and return a proxy card without giving specific voting instructions,
then the Company-designated proxy holders will vote your shares in the manner recommended by our Board on all matters presented in this Proxy Statement and as the proxy holders may determine in their discretion regarding any other matters properly presented for a vote at the meeting.
Beneficial Owners of Shares Held in Street Name.   If you are a beneficial owner of shares and your bank or brokerage firm does not receive instructions from you about how your shares are to be voted, your shares may constitute “broker non-votes.” Broker non-votes occur on a matter when a broker is not permitted to vote on that matter without instructions from the beneficial owner and instructions are not given. These matters are referred to as “non-routine” matters. Brokers have discretionary power to vote your shares with respect to “routine” matters, but they do not have discretionary power to vote your shares on “non-routine” matters.

CORPORATE GOVERNANCE
CORPORATE GOVERNANCE
Prior to the 2023 Bankruptcy Proceedings, the ordinary shares of the Company were traded on the NYSE American LLC (“NYSE American”) under the ticker symbol “MNK.” On September 6, 2023, the New York Stock Exchange (“NYSE”) filed a Form 25 with the SEC to delist our predecessor ordinary shares from the NYSE American. The delisting became effective September 16, 2023. The deregistration of our predecessor ordinary shares under Section 12(b) of the U.S. Securities Exchange Act of 1934, as amended (“Exchange Act”), became effective on December 15, 2023, at which point our ordinary shares were deemed registered under Section 12(g) of the Exchange Act. Our ordinary shares began trading on the Pink Open Market (formerly known as the OTC Pink Marketplace) on August 29, 2023 under the symbol “MNKTQ.” On November 14, 2023, upon Emergence from the 2023 Bankruptcy Proceedings, all of our outstanding ordinary shares were cancelled, and we issued a total of 19,696,335 new ordinary shares. As a result of the cancellation of our predecessor ordinary shares upon Emergence, we ceased trading on the Pink Open Market.
Because our ordinary shares are no longer listed on any national securities exchange, we are no longer subject to the listing rules or standards of an exchange with particular corporate governance requirements. However, we expect to maintain corporate governance documents, policies and procedures guided by what we believe is appropriate in light of our governance structure, U.S. practices and applicable federal securities laws and regulations. Given our recent Emergence from the 2023 Bankruptcy Proceedings and the substantial changes to our Memorandum and Articles of Association and the resulting Board of Directors structure, we are in the midst of a process of substantially revising our Corporate Governance Guidelines and other corporate governance documents, policies and procedures.
Although we are an Irish public limited company, we are not subject to the listing rules of the Euronext Dublin or the listing rules of the U.K. Listing Authority and we are therefore not subject to, nor have we adopted, the U.K. Corporate Governance Code or any other non-statutory Irish or U.K. governance standards or guidelines. While there are many similarities and overlaps between the U.S. corporate governance standards we apply and the U.K. Corporate Governance Code and other Irish and U.K. governance standards or guidelines, there are differences, relating in particular to the extent of the authorization to issue share capital and effect share repurchases that may be granted to the board of directors and the criteria for determining the independence of directors.
Our Board believes that good governance requires not only an effective set of specific practices, but also a culture of responsibility throughout an organization, and governance at Mallinckrodt is intended to achieve both. Our Board also believes that good governance ultimately depends on the quality of an organization’s leadership, and it is committed to recruiting and retaining directors and officers of proven leadership ability and personal integrity.
Size and Composition of the Board
In connection with Emergence from the 2023 Bankruptcy Proceedings, on the 2023 Effective Date, we adopted a new memorandum and articles of association (together, the “Memorandum and Articles of Association”), which replaced and superseded our prior memorandum and articles of association. Pursuant to the Memorandum and Articles of Association, the Board consists of the following:

the Chief Executive Officer of the Company;

one director (the “First Designated Director”) designated by the shareholder on Schedule 1 to the Memorandum and Articles of Association (generally former members of the Ad Hoc First Lien Group Steering Committee) that holds the largest number of issued ordinary shares (the “First Designator”), which the First Designator has the sole right to remove and replace the First Designated Director in accordance with the terms of the Memorandum and Articles of Association for so long as such shareholder continues to hold at least 5% of the nominal value of the issued ordinary shares of the Company (calculated on a fully-diluted basis and excluding equity to be issued under the Mallinckrodt Pharmaceuticals 2024 Stock and Incentive Plan (the “2024 Plan”) and the contingent value rights issued on the 2023 Effective Date (the “CVRs”));

one director (the “Second Designated Director” and, together with the First Designated Director, the “Designated Directors”) designated by the shareholders on Schedule 2 to the Memorandum and Articles of Association (generally former members of the Ad Hoc Crossover Group Steering Committee) (the “Second Designators”), whom the Second Designators have the sole right to remove and replace in accordance with the terms of the Memorandum and Articles of Association for so long as at least one shareholder on Schedule 2 to the Memorandum and Articles of Association holds at least 5% of the nominal value of the issued ordinary shares of the Company (calculated on a fully-diluted basis and excluding equity to be issued under the 2024 Plan and the CVRs); and

four directors who qualify as “independent directors” under the listing requirements of the NYSE, nominated by a nominating and selection committee (the “Nominating and Selection Committee”) described in the Memorandum and Articles of Association (acting by a unanimous resolution), which is generally comprised of former members of the Ad Hoc First Lien Group Steering Committee, the Ad Hoc Crossover Group Steering Committee and the Ad Hoc 2025 Noteholder Group (as defined in the 2023 Plan of Reorganization).
Pursuant to the Memorandum and Articles of Association, our Chair was selected by the Nominating and Selection Committee. In addition, as set out in the Memorandum and Articles of Association, members of committees of the Board were appointed by a majority of the Board and include in all cases each of the Designated Directors.
Our Memorandum and Articles of Association describe in more details the circumstances in which the nomination rights of the Nominating and Selection Committee apply, including the levels of ownership of the Company’s equity securities necessary for those rights. The Nominating and Selection Committee is not a committee of the Board.
The foregoing description is a summary and is qualified in its entirety by the full text of our Memorandum and Articles of Association, which are available on our website at: ir.mallinckrodt.com/corporate-governance/highlights.
On February 2, 2024, (i) Paul M. Bisaro, Katina Dorton, Abbas Hussein and Wesley P. Wheeler were nominated to serve as independent directors of the Board by a unanimous resolution of the Nominating and Selection Committee and were appointed as directors by the Board, (ii) Mr. Bisaro was appointed as the chair of the Board by the Nominating and Selection Committee, and (iii) Mr. Olafsson agreed to remain a member of the Board for an indefinite term. In accordance with the terms of the Memorandum and Articles of Association, each of Mr. Bisaro, Ms. Dorton, Mr. Hussein, Mr. Wheeler and Mr. Olafsson are required to be put forward for re-election at the Annual General Meeting and are therefore included in the nominees described in this Proxy Statement.
Current Designated Directors
On the 2023 Effective Date, Jonathan Zinman was designated as the First Designated Director and David Stetson was designated as the Second Designated Director. In accordance with the terms of the Memorandum and Articles of Association, one of the shareholders on Schedule 1 to the Memorandum and Articles of Association has the sole right to remove and replace Mr. Zinman as a director of the Board and the shareholders on Schedule 2 to the Memorandum and Articles of Association have the sole right to remove and replace Mr. Stetson as a director of Board. In accordance with the terms of the Memorandum and Articles of Association, Mr. Zinman and Mr. Stetson are not required to be put forward for re-election at the Annual General Meeting and are therefore not included in the nominees described in this Proxy Statement.
David Stetson
David Stetson, age 67, has been a director since November 2023. Mr. Stetson has served as the executive chairman of Alpha Metallurgical Resources since 2023 and previously served as its chief executive officer and chairman of the board of directors from 2019 to 2023. Prior to this role, Mr. Stetson served as chairman of the board of directors and chief executive officer of both ANR, Inc. and

Alpha Natural Resources Holdings, Inc. from 2016 until the merger of these entities with Contura (now Alpha) in 2018. Mr. Stetson has held a number of executive leadership positions in various industries, including chief executive officer, chief restructuring officer, general counsel and senior advisor including A.K. Kelly Technologies, Trinity Coal Corporation, American Resources Offshore, Inc., Lexington Coal Company, and Lipari Energy Inc. Mr. Stetson earned a bachelor of science degree from Murray State University, a juris doctor degree from the Brandeis School of Law at the University of Louisville, and a master of business administration degree from the University of Notre Dame. Mr. Stetson’s qualifications to serve on our Board include more than 30 years of experience in various leadership positions and deep insight into strategic applications of financing alternatives, formulation of business strategies, tactical coordination of operational activities, and the ability to maximize strategic values and execute on appropriate solutions.
Jonathan Zinman
Jonathan Zinman, age 44, has been a director since November 2023. Mr. Zinman currently serves as a managing director on the restructuring team at Silver Point Capital since 2019. He previously served as a managing director leading restructurings at Solus Alternative Asset Management, an investment advisor specializing in event-driven and distressed investments, from 2012 to 2019. Prior to Solus, he was an associate in the restructuring practice of Kirkland & Ellis. Mr. Zinman previously served on the boards of directors of Tailored Brands (from 2020 to 2021) and NVHL SA (from 2021 to 2022). He received his J.D. and M.B.A. from the University of Michigan Law School and Stephen M. Ross School of Business as well as his B.A. from Duke University. Mr. Zinman’s qualifications to serve on our Board include his leadership and keen knowledge on restructuring (in particular, issues arising after emergence from bankruptcy) and in-depth expertise in strategies that drive financial and operational transformation.
Independence of Directors
The Board consists of a substantial majority of independent, non-employee directors. The Board has established guidelines for determining director independence that are consistent with the current listing standards of the NYSE. To be considered independent, a director must be determined by the Board to have no material relationship, directly or indirectly, with us. In assessing independence, the Board considers all relevant facts and circumstances. The Governance and Compliance Committee assesses independence and also monitors adherence by the members of the Board with the NYSE corporate governance listing standards for populating the Audit Committee, Human Resources and Compensation Committee (which we sometimes refer to as the “HRCC”) and Governance and Compliance Committee.
The Board has considered the independence of its members in light of these criteria. In making its determinations on independence, the Board considered that Mr. Zinman is employed by Silver Point (one of the largest holders of the Company’s ordinary shares and a party to numerous transactions with the Company in connection with 2023 Bankruptcy Proceedings).
Based on these considerations, the Board has determined that each of our directors, other than Sigurdur O. Olafsson, our President and CEO, satisfies our independence criteria and is independent. Additionally, each of our then-incumbent directors who resigned on November 14, 2023 at the time of our Emergence from the 2023 Bankruptcy Proceedings was previously determined by the Board to have satisfied our independence criteria and deemed to be independent. Each independent director is expected to notify the chair of the Governance and Compliance Committee, as soon as reasonably practicable, of changes in such director’s personal circumstances that may affect the Board’s evaluation of the director’s independence.
Director Nominations Process
Subject to the rights of the First Designator, the Second Designators and the Nominating and Selection Committee as set forth in the Memorandum and Articles of Association, the Governance and Compliance Committee will consider nominations for director submitted by shareholders. To recommend a nominee for director, a shareholder should write to our Corporate Secretary at our registered address, Mallinckrodt plc, College Business & Technology Park, Cruiserath, Blanchardstown, Dublin 15, Ireland.

MALLINCKRODT PUBLIC LIMITED COMPANY – Proxy Statement   9

Abstentions and broker non-votes are considered present for purposes of determining the presence of a quorum. Abstentions and broker non-votes will not be considered votes properly cast at the Annual General Meeting pursuant to our Articles of Association. Because the approval of
all of the proposals is based on the votes properly cast at the Annual General Meeting, abstentions and broker non-votes will not have any effect on the outcome of voting on these proposals under Irish law.
Why did I receive a notice in the mail regarding the internet availability of the proxy materials instead of a paper copy of the proxy materials?
As explained in more detail below, we are using the “notice and access” system adopted by the SEC relating to delivery of our proxy materials over the internet. As a result, we mailed to many of our shareholders a notice about the internet availability of the proxy materials instead of a paper copy of the proxy materials. Shareholders
who received the notice will have the ability to access the proxy materials over the internet and to request a paper copy of the proxy materials by mail, by e-mail or by telephone. Instructions on how to access the proxy materials over the internet or to request a paper copy may be found on the notice. In addition, the notice contains instructions
CORPORATE GOVERNANCE

GENERAL INFORMATION
on how shareholders may request proxy materials in printed form by mail or electronically by e-mail on an ongoing basis. This notice of internet
availability of proxy materials also serves as a Notice of Meeting.
What are the “notice and access” rules and how do they affect the delivery of the proxy materials?
The SEC’s notice and access rules allow us to deliver proxy materials to our shareholders by posting the materials on an internet website, notifying shareholders of the availability of the proxy materials on the internet and sending paper copies of proxy materials upon shareholder request. We believe that the notice and access rules allow us to use internet technology that many
shareholders prefer, continue to provide our shareholders with the information they need and, at the same time, assure more prompt delivery of the proxy materials. The notice and access rules also lower our cost of printing and delivering the proxy materials and minimize the environmental impact of printing paper copies.
Why didn’t I receive a notice in the mail about the internet availability of the proxy materials?
Shareholders who previously elected to access the proxy materials over the internet will not receive a notice in the mail about the internet availability of the proxy materials. Instead, you should have received an e-mail with links to the proxy materials and the proxy voting website. Additionally, we mailed copies of the proxy materials to shareholders who previously requested to receive paper copies instead of the notice.
If you received a paper copy of the proxy materials, you may elect to receive future proxy materials electronically by following the instructions on your
proxy card or voting instruction form. Choosing to receive your future proxy materials by e-mail will help us conserve natural resources and reduce the cost of printing and distributing our proxy materials. If you choose to receive future proxy materials by e-mail, you will receive an e-mail with instructions containing a link to the website where those materials are available and a link to the proxy voting website. Your election to receive proxy materials by e-mail will remain in effect until you terminate it.

The recommendation must also include documentary evidence of ownership of our ordinary shares, as well as the date the shares were acquired and the name and address of the shareholder, in each case as required by our Memorandum and Articles of Association.
To be considered by the Governance and Compliance Committee for nomination and inclusion in our Proxy Statement for the 2025 Annual General Meeting, such shareholder recommendation for director must be received by our Corporate Secretary not earlier than the close of business on February 8, 2025 and not later than the close of business on March 10, 2025; provided, that in the event the date of the 2025 Annual General Meeting is more than 30 days before or more than 60 days after the anniversary of the 2024 Annual General Meeting, notice must be received no earlier than the close of business on the 90th day prior to the date of the 2025 Annual General Meeting and no later than the close of business on the later of the 60th day prior to the date of the 2025 Annual General Meeting or, if the first public announcement of the date of the 2025 Annual General Meeting is less than 100 days prior to the date of the 2025 Annual General Meeting, the 10th day following the day on which public announcement of the date of the 2025 Annual General Meeting is first made. Once our Corporate Secretary receives the recommendation, we will deliver a questionnaire to the candidate requesting additional information about the candidate’s independence, qualifications and other information that would assist the Governance and Compliance Committee in evaluating the candidate, as well as certain information that must be disclosed about the candidate in our Proxy Statement, if nominated. Candidates must complete and return the questionnaire within the time frame provided to be considered for nomination by the Governance and Compliance Committee.
Based on its evaluation, the Governance and Compliance Committee recommended each of the nominees for election by the shareholders. More information regarding each director nominee’s qualifications can be found in Proposal 1 later in this Proxy Statement.
Majority Vote for Election of Directors
Directors are elected by the affirmative vote of a majority of the votes cast by shareholders at the Annual General Meeting (present in person or by proxy) and serve for one-year terms. Any nominee for director who does not receive a majority of the votes cast is not elected to the Board and the position that would have been filled by such nominee will become vacant. Given that Irish law does not recognize the concept of a holdover director, incumbent directors who are subject to re-election who do not receive a majority of the votes cast at the Annual General Meeting are not re-elected to the Board, and immediately following the Annual General Meeting, will no longer be members of the Board unless re-appointed in accordance with our Memorandum and Articles of Association or re-appointed by virtue of holding the CEO position.
Irish law does require, however, a minimum of two directors at all times. If an election results in either only one or no directors receiving the required majority vote, either the nominee or each of the two

CORPORATE GOVERNANCE
CORPORATE GOVERNANCE
On October 27, 2022, Mallinckrodt ordinary shares commenced trading on NYSE American under the symbol “MNK”. Our Corporate Governance Guidelines, general approach to corporate governance and internal policies and procedures are guided by U.S. practice and applicable federal securities laws and regulations as well as NYSE American requirements. Although we are an Irish public limited company, we are not subject to the listing rules of the Euronext Dublin or the listing rules of the U.K. Listing Authority and we are therefore not subject to, nor have we adopted, the U.K. Corporate Governance Code or any other non-statutory Irish or U.K. governance standards or guidelines. While there are many similarities and overlaps between the U.S. corporate governance standards we apply and the U.K. Corporate Governance Code and other Irish and U.K. governance standards or guidelines, there are differences, relating in particular to the extent of the authorization to issue share capital and effect share repurchases that may be granted to the board of directors and the criteria for determining the independence of directors.
Our Board believes that good governance requires not only an effective set of specific practices, but also a culture of responsibility throughout an organization, and governance at Mallinckrodt is intended to achieve both. Our Board also believes that good governance ultimately depends on the quality of an organization’s leadership, and it is committed to recruiting and retaining directors and officers of proven leadership ability and personal integrity.
Corporate Governance Guidelines
The Board has adopted Corporate Governance Guidelines designed to assist Mallinckrodt and the Board in implementing effective corporate governance practices. These guidelines, which are reviewed annually by the Governance and Compliance Committee, address, among other things, director responsibilities and independence, Board composition and selection, the role of the Chairman of the Board or of an independent Lead Director, succession planning, Board and committee self-evaluations, recoupment, or “clawback,” of executive compensation and ethics and conflicts of interest. Our Corporate Governance Guidelines are posted on our website at ir.mallinckrodt.com/corporate-governance/highlights.
Independence of Nominees for Director
The Board believes that a substantial majority of its members should be independent, non-employee directors. The Board has established guidelines for determining director independence that are consistent with the current listing standards of the NYSE American. To be considered independent, a director must be determined by the Board to have no material relationship, directly or indirectly, with us. In assessing independence, the Board considers all relevant facts and circumstances. In particular, when assessing the materiality of a director’s relationship with us, the Board considers the issue not just from the standpoint of the director, but also from that of the persons or organizations with which the director has an affiliation.
The Board has considered the independence of its members in light of these criteria, has reviewed our relationships with organizations and individuals with which our directors and/or their family members are affiliated and has determined that none of these current relationships is material to us, any of the organizations and individuals involved, or our directors. As to Daniel A. Celentano’s independence specifically, the Board considered that one of Mr. Celentano’s immediate family members, and that immediate family member’s spouse, has a personal friendship with an employee of one of Mallinckrodt’s independent compensation consultants.
Based on these considerations, the Board has determined that each of our directors, other than Sigurdur O. Olafsson, our President and CEO, satisfies our independence criteria and is independent. Additionally, each of our then-incumbent directors who resigned on June 16, 2022, at the time of our emergence from Chapter 11 proceedings, other than Mark C. Trudeau, our then-President and CEO, was previously determined by the Board to have satisfied our independence criteria and deemed to be independent. Each independent director is expected to notify the chair of the Governance and Compliance

Committee, as soon as reasonably practicable, of changes in such director’s personal circumstances that may affect the Board’s evaluation of the director’s independence.
Director Nominations Process
The Governance and Compliance Committee is responsible for developing the general criteria, subject to approval by the full Board, used in identifying, evaluating and selecting qualified candidates for election or re-election to the Board. The Governance and Compliance Committee periodically reviews with the Board the appropriate skills and characteristics required of Board members in the context of the then-current make-up of the Board. Final approval of director candidates is determined by the full Board, and invitations to join the Board are extended by the Chairman of the Board on behalf of the entire Board.
The Governance and Compliance Committee, in accordance with our Corporate Governance Guidelines, seeks to create and maintain a Board that is strong in its collective knowledge and has a diversity of backgrounds, skills and experience with respect to accounting and finance, management and leadership, vision and strategy, business operations, business judgment, industry knowledge, corporate governance and global markets. When the Governance and Compliance Committee reviews a potential new candidate, it looks specifically at the candidate’s qualifications in light of our needs and the needs of the Board at that time, given the then-current mix of director attributes.
As described in our Corporate Governance Guidelines:

Directors should be individuals of the highest ethical character and integrity;

Directors should have demonstrated management ability at senior levels in successful organizations, including as the chief executive officer of a public company or as the leader of a large, multifaceted organization, including government, educational and other non-profit organizations;

Each director should have the ability to provide wise, informed and thoughtful counsel to senior management on a range of issues and be able to express independent opinions, while at the same time working as a member of a team;

Directors should be free from any conflict of interest or business or personal relationship that would interfere with their fiduciary duties to Mallinckrodt; and

Directors should be independent of any particular constituency and be able to represent all of our shareholders.
The Governance and Compliance Committee assesses independence and also monitors adherence by the members of the Board with NYSE American corporate governance listing standards for populating the Audit Committee, Human Resources and Compensation Committee (which we sometimes refer to as the “HRCC”) and Governance and Compliance Committee. In general, directors may not serve on more than four public company boards of directors (including ours). If the director is employed as the chief executive officer of a publicly traded company, the director may serve on no more than three public company boards of directors (including ours).
As provided in its charter, the Governance and Compliance Committee will consider nominations submitted by shareholders. To recommend a nominee, a shareholder should write to our Corporate Secretary at our registered address, Mallinckrodt plc, College Business & Technology Park, Cruiserath, Blanchardstown, Dublin 15, Ireland. Any such recommendation must include:

The name and address of the candidate;

A brief biographical description, including his or her occupation for at least the last five years, and a statement of the qualifications of the candidate, taking into account the qualification requirements set forth above; and

The candidate’s signed consent to serve as a director if elected and to be named in our Proxy Statement.

CORPORATE GOVERNANCE
The recommendation must also include documentary evidence of ownership of our ordinary shares if the shareholder is a beneficial owner, as well as the date the shares were acquired and the name and address of the shareholder, as required by our Articles of Association.
To be considered by the Governance and Compliance Committee for nomination and inclusion in our Proxy Statement for the 2024 Annual General Meeting, a shareholder recommendation for director must be received by our Corporate Secretary not earlier than the close of business on January 17, 2024 and not later than the close of business on February 16, 2024, provided, that in the event the date of the 2024 Annual General Meeting is more than 30 days before or more than 60 days after the anniversary of the 2023 Annual General Meeting, notice must be received no earlier than the close of business on the 120th day prior to the date of the 2024 Annual General Meeting and no later than the close of business on the later of the 90th day prior to the date of the 2024 Annual General Meeting or, if the first public announcement of the date of the 2024 Annual General Meeting is less than 100 days prior to the date of the 2024 Annual General Meeting, the 10th day following the day on which public announcement of the date of the 2024 Annual General Meeting is first made. Once our Corporate Secretary receives the recommendation, we will deliver a questionnaire to the candidate requesting additional information about the candidate’s independence, qualifications and other information that would assist the Governance and Compliance Committee in evaluating the candidate, as well as certain information that must be disclosed about the candidate in our Proxy Statement, if nominated. Candidates must complete and return the questionnaire within the time frame provided to be considered for nomination by the Governance and Compliance Committee.
The Governance and Compliance Committee also receives suggestions for director candidates from Board members and, in its discretion, may also employ a third-party search firm to assist in identifying candidates for director. All eight of our nominees for director are current members of the Board. Prior to our emergence from Chapter 11 proceedings on June 16, 2022, in accordance with the Plan, six of our nominees (Paul M. Bisaro, Daniel A. Celentano, Riad H. El-Dada, Neal P. Goldman, Woodrow A. Myers, Jr., M.D. and James R. Sulat) were designated by the Required Supporting Unsecured Noteholders (as defined in the Plan) and approved by the Board. On June 16, 2022, each of our then-incumbent directors resigned, and immediately following their resignations, the six nominees were appointed to the Board in accordance with the Plan. In August 2022, Karen L. Ling was recommended as a director candidate by Paul M. Bisaro, our Chairman, and on August 12, 2022, was appointed to the Board. In September 2022, Susan M. Silbermann was recommended as a director candidate by Sigurdur O. Olafsson, our President and CEO, and on October 5, 2022, was appointed to our Board.
In evaluating candidates for director, the Governance and Compliance Committee uses the guidelines described above, and evaluates shareholder candidates in the same manner as candidates proposed from all other sources. Based on its evaluation, the Governance and Compliance Committee recommended each of the nominees for election by the shareholders. More information regarding each director nominee’s qualifications can be found in Proposal 1 later in this Proxy Statement.
Majority Vote for Election of Directors
Directors are elected by the affirmative vote of a majority of the votes cast by shareholders at the Annual General Meeting (present in person or by proxy) and serve for one-year terms. Any nominee for director who does not receive a majority of the votes cast is not elected to the Board and the position that would have been filled by such nominee will become vacant. Given that Irish law does not recognize the concept of a holdover director, incumbent directors who do not receive a majority of the votes cast at the Annual General Meeting are not re-elected to the Board, and immediately following the Annual General Meeting, will no longer be members of the Board.
Irish law does require, however, a minimum of two directors at all times. If an election results in either only one or no directors receiving the required majority vote, either the nominee or each of the two nominees receiving the greatest number of votes in favor of his or her election shall, in accordance with our Articles of Association, hold office until such director’s successor(s) is elected.

CORPORATE GOVERNANCE
Executive Sessions of the Board
The independent directors generally meet in executive session, without members of management present, at each regularly scheduled Board meeting and at such other times as may be deemed appropriate. At least one such meeting each year is limited to “independent directors” as defined by the NYSE American corporate governance listing standards. Other than the meeting limited to independent directors, these executive sessions may include a discussion with our Chief Executive Officer.
Board Leadership Structure
The positions of Chairman of the Board and CEO are held separately at Mallinckrodt. The Chairman of the Board provides leadership to the Board and works with the Board to define its structure and activities in the fulfillment of its responsibilities. The Chairman of the Board sets the Board agendas with Board and management input, facilitates communication among directors, provides an appropriate information flow to the Board and presides at meetings of the Board and shareholders. The Chairman of the Board works with other Board members to provide strong, independent oversight of our management and affairs. We believe that having a non-executive, independent Chairman of the Board is in the best interests of the Company and our shareholders at this time. The separation of the roles of Chairman of the Board and CEO allows our CEO to focus on managing the Company’s business and operations, and allows our Chairman of the Board to focus on Board matters, especially in light of the high level of regulation and scrutiny of public company boards. Further, we believe that separation of these roles ensures the independence of the Board in its oversight role of evaluating and assessing the CEO and management generally. Future modification of the Board leadership structure will be made at the sole discretion of the Board. A more detailed description of the role and responsibilities of the Chairman of the Board is set forth in our Corporate Governance Guidelines.
Code of Conduct
We have adopted the Mallinckrodt Code of Conduct, which meets the requirements of a “code of ethics” as defined in Item 406 of Regulation S-K and meets the requirements of a code of business conduct and ethics under the NYSE American corporate governance listing standards. Our Code of Conduct applies to all employees, officers and directors of Mallinckrodt, including, without limitation, our CEO, CFO and other senior financial officers, and is reviewed annually by our Governance and Compliance Committee. Our Code of Conduct is posted on our website at mallinckrodt.com under the heading “Investor Relations — Corporate Governance.” We will also provide a copy of our Code of Conduct to shareholders upon request. We intend to disclose any amendments to our Code of Conduct, as well as any waivers for executive officers or directors, on our website.
Board Risk Oversight
Our Board oversees an enterprise-wide approach to risk management designed to support the achievement of organizational objectives, including strategic objectives, to improve long-term organizational performance and enhance shareholder value. A fundamental part of risk management is not only understanding the risks we face and what steps management is taking to manage those risks, but also understanding what level of risk is appropriate for us. The involvement of the full Board in approving our business strategy is a key part of its assessment of management’s appetite for risk and the determination of what constitutes an appropriate level of risk for us. In this process, risk is assessed throughout the business, focusing on three primary areas: financial risk; legal/compliance risk; and operational/strategic risk.Board Leadership Structure
The positions of Chair of the Board and CEO are held separately at Mallinckrodt. The Chair of the Board, selected by the Nominating and Selection Committee, provides leadership to the Board and works with the Board to define its structure and activities in the fulfillment of its responsibilities. The Chair of the Board sets the Board agendas with Board and management input, facilitates communication among directors, provides an appropriate information flow to the Board and presides at meetings of the Board and shareholders.

While the full Board has the ultimate oversight responsibility for the risk management process, various committees of the Board also have responsibility for risk management. In particular, the Audit Committee oversees, conducts an annual assessment of and reports to the Board on our enterprise risk management program, focuses on financial risk, including internal controls over financial reporting, and receives an annual risk assessment report from our internal auditors, and oversees reporting requirements related to environmental, social and governance (“ESG”) and ESG-related risks. The Governance and Compliance Committee assists the Board in fulfilling its oversight responsibility with

respect to regulatory, healthcare compliance, ESG strategy and best practices and public policy issues that affect us and works closely with our legal and regulatory groups. In addition, in setting compensation, the HRCC strives to create incentives that encourage a level of risk-taking behavior consistent with our business strategy. The HRCC also oversees diversity and inclusion initiatives, including in relation to our ESG reporting. The full Board has primary oversight with respect to cybersecurity and information security-related risks.
Environmental, Social and Governance
We strive to be a force for good. We are committed to doing more and are taking steps to ensure we operate and grow responsibly. We believe ESG programs are foundational to creating long-term value for all our stakeholders, including shareholders, patients, employees, customers, and the communities in which we operate and live.
ESG Governance
Our Board of Directors is responsible for incorporating ESG into its long-term strategy and risk management. At the operational level, ESG is managed by our Executive Vice President and Chief Transformation Officer who leads a cross-functional ESG Steering Committee responsible for strategy implementation, stakeholder engagement, disclosures, reporting and communications. Cross-functional working groups manage specific ESG programs and initiatives to support progress and ensure accountability.
Communications with the Board of Directors
The Board has established a process for interested parties to communicate with members of the Board. If you have a concern, question or complaint regarding our compliance with any policy or law, or would otherwise like to contact the Board, you may reach the Board via e-mail at board.directors@mnk.com. A direct link to this e-mail address can be found on our website. You may also submit communications in writing or by phone. Please refer to the Board contact information that can be found at mallinckrodt.com/contact-us/. All concerns and inquiries are received and reviewed promptly by the Office of the General Counsel. Any significant concerns relating to accounting, internal controls over financial reporting or audit matters are reviewed with the Audit Committee.
All concerns will be addressed by the Office of the General Counsel, unless otherwise instructed by the Audit Committee or the Chair of the Board. The status of all outstanding concerns is reported to the Chair of the Board and the Audit Committee on a quarterly basis, and any concern that is determined to pose an immediate threat to us or concern one of our senior officials (any executive officer or any direct report to the President and CEO) is immediately communicated to the Chair of the Board and Chair of the Audit Committee. The Chair of the Board or the Audit Committee may determine that certain matters should be presented to the full Board and may direct the retention of outside counsel or other advisors in connection with any concern addressed to them. The Mallinckrodt Code of Conduct prohibits any employee from retaliating against anyone for raising or helping to resolve an integrity question. The Governance and Compliance Committee, comprised entirely of independent, non-employee directors, has reviewed and approved the foregoing procedures and is responsible for recommending changes to the procedures as necessary.

Our business, property and affairs are managed under the direction of the Board. Directors are kept informed about our business through discussions with the Chair of the Board and the CEO and other officers, by reviewing materials provided to them and by participating in meetings of the Board and its committees.

During fiscal 2023, each of our incumbent directors attended 75% or more of the aggregate of the total number of (i) meetings of our Board (held during the period for which he or she was a director) and (ii) meetings held by all committees of our Board on which he or she served (during the period for which he or she served). Our Board members are expected to attend our Annual General Meeting. All of our directors who were members of the Board at the time attended our 2023 Annual General Meeting in person or by phone.

Membership and chairs of the committees are recommended by the Governance and Compliance Committee. The Memorandum and Articles of Association provide that members of committees of the Board are appointed by a majority of the Board and must include in all cases each of the Designated Directors unless any Designated Director(s) declines, in his or her sole discretion, to serve on such committee (subject to customary exclusions of directors from meetings of committees considering affiliated transactions). The description of the Board committees in this paragraph does not include the Nominating and Selection Committee, which is not a committee of the Board and was formed pursuant to the Memorandum and Articles of Association (as described in the section entitled “Size and Composition of the Board” on page 7).
The committees report on their activities to the Board at each regular Board meeting.

We believe creating a sustainable supply base and deploying environmentally preferable business practices is critical to our long-term success and growth.
We continually seek opportunities to conserve resources by improving efficiencies, introducing renewable energy sources, reducing our consumption and minimizing waste. In particular, in 2022:

our manufacturing site and office in Dublin, Ireland, sourced 100% renewable electricity;

electric vehicle charging stations were installed at four of our corporate offices to encourage sustainable transportation;

more than 87% of hazardous waste generated across the Company was recycled or reclaimed, and the remaining hazardous waste was disposed of in a traditional waste management manner, appropriately and in accordance with local laws and regulations; and

our manufacturing site located in St. Louis, Missouri reduced its water usage by more than 50% in the past six years, as part of an intensive water conservation program.

The 2023 non-employee director compensation for directors who served prior to Emergence consisted of an annual cash retainer and equity awards, as described below. The equity awards granted to each non-employee director as part of the annual fiscal 2023 equity grant were subsequently cancelled in June 2023 and each non-employee director who served prior to Emergence received additional cash compensation, as further described below.

Dr. Richardson was an NEO for fiscal 2023 as a result of his Inducement Grant provided in connection with his commencement of employment with the Company in 2023. For further information on the Inducement Grant, see the section entitled “— 2023 Awards — Inducement Grant” below.
Compensation Decision-Making
Role of the HRCC and Management
Leading up to fiscal 2023, in September and December of 2022, and in February 2023, the HRCC reviewed our key executive compensation policies, practices and plans to determine whether they were consistent with our compensation philosophy and objectives, and whether they needed to be modified in light of changes in our business or the market. The overall value of compensation was compared to market data on compensation opportunities at pharmaceutical industry and peer companies to ensure that our executive pay programs are positioned competitively. The HRCC and the Board considered the mix of variable and fixed compensation when determining base salary and short- and long-term incentives with an emphasis on variable compensation rather than fixed compensation. Our CEO made recommendations to the HRCC regarding salary adjustments and the setting of incentive targets and awards for the executives (other than himself) and the HRCC approved the fiscal 2023 executive compensation programs. The HRCC reported to the Board on compensation paid to the executives and made recommendations to the Board regarding CEO compensation. The Board approved the CEO compensation.
The fiscal 2023 executive compensation program, when originally approved on February 14, 2023, included base salary, a 2023 Short-Term Incentive Plan (“2023 STIP”) and a 2023 Long-Term Incentive Plan (“2023 LTIP”). In connection with the 2023 Bankruptcy Proceedings, on June 14, 2023, upon the recommendation of the independent directors of the Board, the Board approved the 2023 Key Employee Incentive Plan (“2023 KEIP”) and the 2023 Key Employee Retention Program (“2023 KERP”).
The 2023 KEIP was implemented in the time leading up to the 2023 Bankruptcy Proceedings to replace the 2023 STIP and the 2023 LTIP for the participants in the 2023 KEIP. The 2023 KERP was implemented at the same time as the 2023 KEIP in order to provide a retention program for key officers who were participants in the program. Mr. Olafsson elected not to participate in the 2023 KEIP or the 2023 KERP and instead continued his participation in the 2023 STIP and the 2023 LTIP. Additional details of the 2023 STIP, 2023 LTIP, 2023 KEIP and 2023 KERP can be found in the section entitled “Narrative to Summary Compensation Table”.
Role of the Compensation Consultant
The HRCC utilizes the services of independent compensation consultants from time to time and has the sole authority to retain, compensate and terminate any such compensation consultants. During fiscal 2023, LB&Co. served as the independent compensation consultant to the HRCC. LB&Co. reported directly to the HRCC, and within its scope of services, LB&Co. reviewed HRCC materials, attended all HRCC meetings, reviewed our peer group (a group of companies reasonably similar to us in size that may be in competition with us for executive talent) and competitive positioning of individual executives versus market, advised the HRCC on program design, provided advice to the HRCC as compensation issues arose and provided recommendations on certain specific aspects of our compensation

programs. In connection with setting fiscal 2023 compensation, the HRCC assessed the independence of LB&Co. and determined that LB&Co. was independent and that no conflicts of interest existed.
Summary Compensation Table
The information presented in the Summary Compensation Table reflects compensation for our NEOs for fiscal 2023. However, the impact of the 2023 Bankruptcy Proceedings on equity compensation is not reflected in the Summary Compensation Table. In connection with Emergence from the 2023 Bankruptcy Proceedings on November 14, 2023, each existing equity interest in Mallinckrodt, including our ordinary shares and existing equity-based awards, was cancelled and extinguished. Accordingly, our NEOs did not receive any value for their equity interests in Mallinckrodt.

Narrative to Summary Compensation Table
Fiscal 2023 STIP Award
In connection with the 2023 Bankruptcy Proceedings, on June 14, 2023, we implemented the 2023 KEIP and the 2023 KERP. Mr. Olafsson elected not to participate in either of these programs and instead continued his participation in the 2023 STIP and the 2023 LTIP. Mr. Olafsson’s target bonus for fiscal 2023 was based on his 2023 STIP target bonus only and did not include a long-term incentive equivalent percentage like the 2023 KEIP, as further discussed below. The table below shows the target award opportunity for Mr. Olafsson as a percentage of his base salary under the 2023 STIP.
2023 Short-Term Incentive Plan Target as a % of Salary
Sigurdur O. Olafsson135%
The 2023 STIP provided Mr. Olafsson with the opportunity to receive an incentive payment determined by multiplying his incentive target percentage by the Company’s achievement against pre-determined financial performance targets and then by an individual performance modifier. The Company performance targets were designed to be achieved in a range from 0% (achievement at less than threshold) to 200% (achievement at maximum or above) of target based upon our performance, subject to an individual performance modifier that could also be applied, with a cap of 250% of base salary on the total target opportunity as set by Mr. Olafsson’s employment agreement. The following illustrates the formula for the STIP:
[MISSING IMAGE: fc_annual-bw.jpg]
2023 STIP Performance Periods and Measures.   The 2023 STIP consisted of two standalone performance periods: the First Half (50% of award) and the Second Half (50% of award). The performance measures for each period were separately determined and were based for each period on Adjusted EBITDA and Adjusted Free Cash Flow (each as defined below), weighted 50% and 50%, respectively. These performance measures were set in relation to our annual budget for the enterprise as approved by the Board.
“Adjusted EBITDA” means net income or loss before interest, income taxes, depreciation and amortization adjusted to exclude the following items: share-based compensation (settled in either stock or cash); the impact of acquisitions and divestitures; any significant unbudgeted foreign exchange (gain)/loss occurring in selling, general and administrative expenses; any 2023 KERP related expenses; any 2023 KEIP related expenses in excess of budgeted annual incentive plan amounts; any restructuring related expenses in or out of court; and any unusual or nonrecurring items approved by the HRCC or the Board.
“Adjusted Free Cash Flow” means net cash from operating activities minus capital expenditures and excluded the following items: any payments related to the Company’s emergence from bankruptcy (examples would include opioid defense costs, legal and advisory fees, trust administration costs, etc.); CARES Act refund(s); any 2023 KERP or 2023 KEIP related payments in excess of budgeted annual incentive plan amounts; any restructuring related expenses in or out of court; opioid and Department of Justice (“DOJ”) and Centers for Medicare & Medicaid Services (“CMS”) settlements; the impact of acquisitions and divestitures; and any unusual or nonrecurring items approved by the HRCC or the Board.
The weighted average funding for the 2023 STIP was designed to range from 0% to 200% of target based upon our performance against the two measures. The following chart summarizes the 2023 STIP design with respect to the Company performance measures, including the relative weighting,

The following charts show the HRCC approved financial multiplier and individual performance modifier for the First Half payment and the Second Half payment for Mr. Olafsson. In determining Mr. Olafsson’s individual performance modifier, the HRCC considered Mr. Olafsson’s contributions, including the following: successfully entering into a pre-packed Chapter 11 process and emerging within a condensed period of time; exceeding the high end of the guidance range on annual net sales and Adjusted EBITDA; the successful launch of Terlivaz; FDA clearance of Inomax with anticipated rollout in 2024; FDA acceptance of the Supplementary New Drug Application for the Acthar Gel Single-Dose Pre-filled SelfJect™ Injector; and three successful product launches within our Specialty Generics business (generic Mydayis, generic Vyvanse Capsules, and Morphine Sulfate tablets).

Fiscal 2023 KEIP Awards
The 2023 KEIP was implemented in the time leading up to the 2023 Bankruptcy Proceedings to replace the 2023 STIP and the 2023 LTIP for the participants in the 2023 KEIP. The HRCC established the same performance periods (First Half and Second Half) and measures (Adjusted EBITDA and Adjusted Free Cash Flow) for the 2023 KEIP as the 2023 STIP. Unlike the 2023 STIP, each of Mr. Reasons’

COMPENSATION OF EXECUTIVE OFFICERS
and Dr. Richardson’s KEIP target awards equaled the sum of 100% of his 2023 STIP target bonus and 60% of his 2023 LTIP award value.
The 2023 KEIP provided an opportunity for Mr. Reasons and Dr. Richardson to receive an incentive payment determined by multiplying each executive’s 2023 KEIP incentive target percentage by the Company’s achievement against pre-determined financial performance targets. The Company performance targets were designed to be achieved in a range from 0% (achievement at less than threshold) to 150% (achievement at maximum or above) of target based upon Company performance. The table below shows the full year target award opportunity for Mr. Reasons and Dr. Richardson.

2023 Grants
Annual Grants
On April 3, 2023, our NEOs were granted a 2023 annual equity award, which we refer to as the 2023 LTIP, under the Mallinckrodt Pharmaceuticals 2022 Stock and Incentive Plan (“2022 Plan”), and which consisted of a mix of PSUs (weighted 50%) and RSUs (weighted 50%). The table below sets forth the 2023 annual grant with respect to long-term incentive compensation. Mr. Reasons’ and Dr. Richardson’s 2023 LTIP awards were canceled at the time the 2023 KEIP was implemented. Mr. Olafsson elected not to participate in the 2023 KEIP or the 2023 KERP and instead continued his participation in the 2023 STIP and the 2023 LTIP.

Bryan Reasons301,121132,884168,237
Peter Richardson228,853100,992127,861
PSUs.   PSUs represented unissued ordinary shares; no ordinary shares were to be issued until the applicable vesting requirements had been satisfied with the Company having the discretion to settle in shares or cash. The PSUs were based upon Adjusted Operating Cash Flow (as defined below) and Relative TSR (as defined below) targets, each weighted at 50%, over a performance period of fiscal year 2023 through fiscal year 2025 (December 31, 2022 through December 26, 2025).
“Adjusted Operating Cash Flow” means net cash from operating activities of continuing operations for the performance cycle, excluding the following items: payments related to the Company’s emergence from bankruptcy (examples would include opioid defense costs, legal and advisory fees, trust administration costs, etc.); CARES Act refunds; interest payments; opioid and DOJ and CMS settlements; the impact of acquisitions and divestitures; and any unusual or nonrecurring items approved by the HRCC or the Board.
“Relative TSR” means our total shareholder return as compared to the Russell 2000 Biotechnology Subsector index. This group of companies was broader than the peer group of companies used for competitive comparisons of executive compensation, and it included some companies that are much larger or smaller than Mallinckrodt. The multiplier used to determine the number of earned PSUs could be between a threshold of 50% and a maximum of 200%, with threshold achievement corresponding to a Relative TSR level at the 25th percentile (below which no PSUs are earned) and maximum achievement corresponding to a Relative TSR level at the 75th percentile.

28   MALLINCKRODT PUBLIC LIMITED COMPANY – Proxy Statement

COMPENSATION OF EXECUTIVE OFFICERS
RSUs.   RSUs represented unissued ordinary shares; no ordinary shares were to be issued until the applicable vesting requirements had been satisfied with Company discretion to settle in shares or cash. When the vesting requirements were satisfied, the executive was to receive ordinary shares without restriction or cash. RSUs granted to NEOs during fiscal 2023 were to vest one-third annually beginning on the first anniversary of the grant date.
Inducement Grant
In connection with Dr. Richardson’s commencement of employment with the Company, he received an inducement grant (“Inducement Grant”) consisting of a mix of PSUs (weighted 50%) and RSUs (weighted 50%). The table below sets forth the Inducement Grant with respect to long-term incentive compensation.

PSUs.   The vesting requirements for Dr. Richardson’s PSUs were based upon Adjusted Operating Cash Flow and Relative TSR targets, each weighted at 50%, over a performance period of the second half of fiscal 2022 to fiscal year end 2024 (July 2, 2022 through December 27, 2024). This reflected the same time period and targets that were used for the then-serving executives who had been granted initial awards in December 2022.
RSUs.   The RSUs included in Dr. Richardson’s Inducement Grant were set to vest one-third annually beginning on the first anniversary of his hire date with the Company in 2023.
2023 KERP Awards
In June 2023, the Board approved the 2023 KERP for specified employees, including Mr. Reasons and Dr. Richardson. Although a retention bonus under the 2023 KERP was offered to Mr. Olafsson, he elected not to participate. The HRCC considered the challenges facing the Company, and both the Board and the HRCC believed it critical to continue to stabilize the executive leadership team and reduce the possibility of turnover during a critical time at the Company. Such turnover would have resulted in the loss of expert knowledge and slowed momentum and could have impaired the Company’s ability to continue to navigate the challenges. The HRCC consulted both Willis Towers Watson, the consultant engaged to provide advice to management with respect to certain compensation issues and recommendations in anticipation of filing for the 2023 Bankruptcy Proceedings, and LB&Co., the HRCC’s independent compensation consultant, on the plan and approaches utilized by other companies facing similar uncertainties for retention of executives in determining the value of the retention bonuses. The HRCC and the Board approved awards under the 2023 KERP for Mr. Reasons and Dr. Richardson in the following amounts.
Fiscal 2023 KERP Awards
We supported STEM education helping to expanded opportunities for female and minority students, further closing the gap in access for these underrepresented groups. Examples of 2022 grant support include:

Students 2 Science, a New Jersey-based nonprofit that inspires and educates students in underserved communities to pursue STEM careers.

Maydm, Inc., a nonprofit in Madison, Wisconsin that provides girls and youth of color in grades 6 – 12 with skill-based training in STEM fields.

Millbrook Robotics “GearCats” Booster Club that provides invaluable hands-on STEM education and experience for the students at Millbrook High School, one of North Carolina’s largest and most diverse public high schools.
Respect for Human Rights
We are committed to conducting all of our activities in accordance with high standards of business conduct. We forbid forced child labor, human trafficking and unsafe working conditions, and condemn behaviors that do not support human dignity and respect. We expect our businesses and suppliers to pay fair wages and provide safe working environments free of all human rights violations, as highlighted in our Supplier Code of Conduct. Since fiscal 2017, we have published an annual U.K. Modern Slavery Act Disclosure that sets forth information regarding the steps we have taken to mitigate the risks associated with modern slavery in our business and supply chain.
Anti-Bribery and Anti-Corruption
We are committed to compliance with all applicable global anti-corruption laws, including the U.S. Foreign Corrupt Practices Act (FCPA) and U.K. Bribery Act of 2010. We maintain an anti-bribery and anti-corruption policy to ensure that all of our businesses and employees are aware of their associated responsibilities. We have voluntarily certified to the Pharmaceutical Research and Manufacturers of America Code on Interactions with Health Care Professionals.
Transactions with Related Persons
The Governance and Compliance Committee is responsible for the review and, if appropriate, approval or ratification of “related-person transactions” involving us or our subsidiaries and related persons. Under SEC rules, a related person is a director, nominee for director, executive officer or a beneficial owner of 5% or more of our ordinary shares and their immediate family members. The Board has adopted written policies and procedures that apply to any transaction or series of transactions in which we or one of our subsidiaries is a participant, the amount of which exceeds the lesser of $120,000 or one percent of the average of our total assets at year end for the last two completed fiscal years, and the related person has a direct or indirect material interest. Based on Mallinckrodt’s review of its transactions, there have been no transactions or proposed transactions considered to be related party transactions since January 1, 2022.
Communications with the Board of Directors
The Board has established a process for interested parties to communicate with members of the Board. If you have a concern, question or complaint regarding our compliance with any policy or law, or would otherwise like to contact the Board, you may reach the Board via e-mail at board.directors@mnk.com. A direct link to this e-mail address can be found on our website. You may also submit communications in writing or by phone. Please refer to the Board contact information that can be found at mallinckrodt.com/contact-us/. All concerns and inquiries are received and reviewed promptly by the Office of the General Counsel. Any significant concerns relating to accounting, internal controls over financial reporting or audit matters are reviewed with the Audit Committee.

The awards ceased to be subject to repayment on November 14, 2023, the date of Emergence from the 2023 Bankruptcy Proceedings.
Other Benefits
We provide NEOs the same benefits that are provided to all employees, including defined contribution retirement benefits and health and welfare benefits. In addition, our NEOs are provided with certain additional benefits, intended to be competitive with the practices of our peer companies.

determined to pose an immediate threat to us or concern one of our senior officials (any executive officer or any direct report to the President and Chief Executive Officer) is immediately communicated to the Chair of the Audit Committee. The Chairman of the Board or the Audit Committee may determine that certain matters should be presented to the full Board and may direct the retention of outside counsel or other advisors in connection with any concern addressed to them. The Mallinckrodt Code of Conduct prohibits any employee from retaliating against anyone for raising or helping to resolve an integrity question. The Governance and Compliance Committee, comprised entirely of independent, non-employee directors, has reviewed and approved the foregoing procedures and is responsible for recommending changes to the procedures as necessary.
COMPENSATION OF EXECUTIVE OFFICERS
Retirement Benefits.   The NEOs are eligible to participate in our Retirement Savings and Investment Plan (“Mallinckrodt Retirement Savings Plan”), which is our 401(k) plan available to all eligible U.S. employees, and our Supplemental Savings and Retirement Plan (“Mallinckrodt Supplemental Savings Plan”), our non-qualified deferred compensation plan in which executive officers and other senior employees may participate. The Mallinckrodt Supplemental Savings Plan is a so-called “excess” plan that extends the 401(k) benefits beyond the Internal Revenue Code (the “Code”) limitations.
Mallinckrodt Retirement Savings Plan.   Under the Mallinckrodt Retirement Savings Plan, we make an automatic contribution of 3% of an employee’s eligible pay, irrespective of whether the employee contributes to such plan. Additionally, we match $0.50 for every dollar employees contribute, up to the first 8% of eligible pay up to the applicable IRS limits ($330,000 for 2023).
Participants are fully vested in Company contributions (including earnings on such contributions) upon the earlier of completion of two years of service or attainment of age 55.
Mallinckrodt Supplemental Savings Plan. Under the Mallinckrodt Supplemental Savings Plan, participants are eligible to receive Company credits of 6% on any cash compensation (i.e., base and bonus) that the participant earns during a calendar year in excess of applicable IRS limits ($330,000 for 2023).
Participants are fully vested in Company credits (including earnings on such credits) upon completion of two years of service. The Mallinckrodt Supplemental Savings Plan is a non-qualified deferred compensation plan that is maintained as an unfunded “top-hat” plan and is designed to comply with Section 409A of the Code. Amounts credited to the Mallinckrodt Supplemental Savings Plan as Company credits may also be credited with earnings (or losses) based upon investment selections made by each participant from investments that generally mirror investments offered under the Mallinckrodt Retirement Savings Plan. Participants may elect whether they will receive a distribution of their Mallinckrodt Supplemental Savings Plan account balances upon termination of employment or at a specified date. Distributions can be made in a lump sum or in up to 15 annual installments.

Upon our Emergence from the 2020 Bankruptcy Proceedings on June 16, 2022, we entered into an employment agreement (as subsequently amended and restated, the “Prior CEO Agreement”) with Mr. Olafsson, pursuant to which Mr. Olafsson commenced service as our CEO effective as of June 25, 2022 (the “Start Date”), for an indefinite term.
Pursuant to the Prior CEO Agreement, Mr. Olafsson received an annual base salary of $1,100,000. Mr. Olafsson was also eligible to receive a performance-based annual bonus with a target amount of 135% of base salary and a maximum amount of 250% of base salary. In addition, the Prior CEO Agreement provided that on or within 30 calendar days following the Start Date, Mr. Olafsson would be granted a one-time equity award, and beginning in fiscal 2023, and for each subsequent fiscal year, Mr. Olafsson would be eligible to receive equity awards (the “Annual Grant”). The Prior CEO Agreement provided that target value for the Annual Grant in respect of fiscal 2023 was to be not less than $4,000,000.
The Prior CEO Agreement provided that Mr. Olafsson would be restricted from competing with us and from soliciting our employees and business partners during the 12-month period following his termination of employment for any reason. In June 2023, the Prior CEO Agreement was further amended to provide that in the event of a severance-qualifying termination, the non-competition covenant in the Prior CEO Agreement would apply only if the applicable severance benefits were paid in full (the “CEO Severance Amendment”).
On February 2, 2024, we entered into a new employment agreement with Mr. Olafsson (the “New CEO Agreement”), which superseded the Prior CEO Agreement. For additional information, see our Current Report on Form 8-K filed February 2, 2024, which includes a summary of the material terms of the New CEO Agreement.

Employment Agreements with Other NEOs
Following Emergence from the 2023 Bankruptcy Proceedings, we entered into amended and restated employment agreements with our NEOs, as further described below.
Employment Agreement with Mr. Reasons
We entered into an employment agreement (as subsequently amended and restated, the “Prior CFO Agreement”) with Mr. Reasons on August 17, 2022. Pursuant to the Prior CFO Agreement, Mr. Reasons received an annual base salary of $630,000. Mr. Reasons was also eligible to receive a performance-based annual bonus with a target amount of 75% of base salary and a maximum amount of 150% of base salary. In addition, the Prior CFO Agreement provided that as soon as reasonably practicable following the effective date of the Prior CFO Agreement, Mr. Reasons would be granted a one-time equity award, and beginning in fiscal 2023, and for each subsequent fiscal year, Mr. Reasons would be eligible to receive equity awards under our equity compensation plans.
The Prior CFO Agreement provided that Mr. Reasons would be restricted from competing with us and from soliciting our employees and business partners during the 12-month period following his termination of employment for any reason. In June 2023, the Prior CFO Agreement was further amended to provide that in the event of a severance-qualifying termination, the non-competition covenant in the Prior CFO Agreement would apply only if the applicable severance benefits were paid in full.
On February 2, 2024, we amended and restated the Prior CFO Agreement (as so amended and restated, the “New CFO Agreement”). The New CFO Agreement is substantially similar to the Prior CFO Agreement, except that the New CFO Agreement provides that Mr. Reasons will participate in the 2024 Plan and the Transaction Incentive Plan, and contains certain changes discussed below under “— Potential Payments Upon Termination.”
Employment Agreement with Dr. Richardson
We entered into an employment agreement (the “Prior CSO Agreement”) with Dr. Richardson on January 12, 2023. Pursuant to the Prior CSO Agreement, Dr. Richardson received an annual base salary of $575,000. Dr. Richardson was also eligible to receive a performance-based annual bonus with a target amount of 75% of base salary and a maximum amount of 150% of base salary.

The Prior CSO Agreement provided that Dr. Richardson would be restricted from competing with us and from soliciting our employees and business partners during the 12-month period following his termination of employment for any reason. In June 2023, the Prior CSO Agreement was further amended to provide that in the event of a severance-qualifying termination, the non-competition covenant in the Prior CSO Agreement would apply only if the applicable severance benefits were paid in full.
On February 2, 2024, we amended and restated the Prior CSO Agreement (as so amended and restated, the “New CSO Agreement”). The New CSO Agreement is substantially similar to the Prior CSO Agreement, except that the New CSO Agreement provides that Dr. Richardson will participate in the 2024 Plan and the Transaction Incentive Plan and contains certain changes discussed below under “— Potential Payments Upon Termination.”
Outstanding Equity Awards At Fiscal Year End
On November 14, 2023, in connection with our Emergence from the 2023 Bankruptcy Proceedings and the cancellation of all of our then-existing ordinary shares, all outstanding equity-based awards under the 2022 Plan were automatically cancelled without consideration and the 2022 Plan was of no further

force and effect with respect to any equity-based awards thereunder. As a result, there were no outstanding equity awards at 2023 fiscal year end.
Anti-Hedging/Anti-Pledging Policy
Our Insider Trading Policy prohibits directors, officers and employees from entering into or trading in puts, calls, cashless collars, options or similar rights and obligations or any other hedging activity involving our securities, other than the exercise of a Company-issued stock option.
Our policy also prohibits directors, officers and employees from purchasing our securities on margin, borrowing against our securities held in a margin account or pledging our securities as collateral for a loan. However, an exception may be granted by our Chief Legal Officer if the individual clearly demonstrates the financial capacity to repay the loan without resort to the pledged securities.
Executive Financial Recoupment Program (“Clawback”)
Since the Company’s separation from Covidien plc in 2013, the Corporate Governance Guidelines have mandated that the Company have a Board-approved policy for recoupment of incentive compensation. This policy was originally implemented by the Board in 2014 and was most recently amended in 2022 in connection with the Company’s corporate integrity agreement entered into with the Office of Inspector General of the Department of Health and Human Services. Mallinckrodt’s policy states that in the event of an accounting restatement resulting from material non-compliance with financial reporting requirements under applicable law, the Board or, if so designated by the Board, the HRCC, is authorized to recover any incentive compensation that was overpaid taking into account such factors as the Board or the HRCC deems appropriate. In addition, Mallinckrodt’s policy states that in the event of certain events of significant misconduct, including a violation of law or regulation or a significant violation of a Company policy, to the extent permitted by law, the Company must seek to recoup cash awards and all or a portion of the cash awards or the realized value of equity awards for the three year period prior to the recoupment determination.
Under Mallinckrodt’s policy, the Company agreed to disclose annually whether, at any time during the last completed fiscal year, the Board required recoupment or forfeiture of any incentive compensation received by certain employees, including NEOs, (1) if required by law, and (2) if not required by law, so long as the disclosure (a) would not violate any individual’s privacy rights, (b) is not likely to result in or exacerbate any existing or threatened employee, shareholder or other litigation, arbitration, investigation or proceeding against the Company and (c) is not otherwise prohibited. Subject to the exceptions described in the previous sentence, if any such recoupment or forfeiture under the policy occurred, we are required to disclose the general circumstances of the recoupment and/or forfeiture, and if no such recoupment or forfeiture occurred during the last completed fiscal year, we are required to disclose that no such event occurred.
In 2023, there was no recoupment or forfeiture applied to the incentive compensation of any executive of the Company.
2023 Say-on-Pay Vote
We consider the views of our shareholders in designing our executive compensation program and value feedback on our compensation practices. At our 2023 Annual Meeting of Shareholders, approximately 91% of the votes cast on our annual advisory vote on the compensation of our NEOs were in favor of this proposal. We believe that the level of support received for this proposal affirms our approach to executive compensation. See page 51 for this year’s say-on-pay proposal.

Under the New CEO Agreement, in the event that Mr. Olafsson’s employment is terminated by the Company without Cause or by Mr. Olafsson with Good Reason, Mr. Olafsson will be entitled to the following severance compensation and benefits: (a) an amount equal to 2x the sum of his annual base salary and target annual bonus payable in installments; (b) a lump sum payment of a prorated target annual bonus with respect to the year in which the termination occurs; (c) our payment of COBRA premiums for 18 months or until he becomes eligible for comparable benefits through a new employment; and (d) our coverage of the cost of outplacement services for up to 12 months.
Under both the Prior CEO Agreement and the New CEO Agreement, in the event that Mr. Olafsson’s employment is terminated by the Company without Cause or by Mr. Olafsson with Good Reason during the period beginning 120 days prior to and ending 24 months after a Change in Control (as defined in each agreement), Mr. Olafsson will receive the applicable foregoing severance benefits with the following enhancements: the base salary and bonus severance will be a lump sum payment of 2.5 times the sum of his annual base salary and target annual bonus, and all of Mr. Olafsson’s unvested and outstanding RSUs, PSUs and other equity-based awards will immediately vest as of the effective date of the release or the Change in Control, if later.
The terms of both the Prior CEO Agreement and the New CEO Agreement provide for certain benefits upon Mr. Olafsson’s termination of employment due to death, disability or retirement. For this purpose, normal retirement occurs where Mr. Olafsson terminates employment after attaining age 60 and the sum of his age and years of service equals at least 70; provided that when Mr. Olafsson attains age 60, he will be credited by the Company with an additional four years of service for purposes of meeting this requirement. Mr. Olafsson is eligible to receive a prorated target bonus upon a termination of employment as a result of his death or disability and, except upon termination of his employment by the Company for Cause, any unpaid annual bonus earned in a prior calendar year, based on the actual level of achievement of the applicable targets or performance as determined by the HRCC at the end of such calendar year.
For purposes of both the Prior CEO Agreement and the New CEO Agreement, “Cause” means, as more fully described in such agreements, (i) substantial refusal of the CEO to perform the duties and responsibilities of his job as required by the Board other than due to incapacity; (ii) a material violation of any fiduciary duty or duty of loyalty owed to us; (iii) conviction of misdemeanor (other than a traffic offense) involving moral turpitude or felony; (iv) any willful act or omission of fraud, embezzlement or theft; (v) any uncured violation of a material rule or policy; or (vi) any unauthorized disclosure of any of our trade secrets or confidential information.
For purposes of both the Prior CEO Agreement and the New CEO Agreement, “Good Reason” means, as more fully described in such agreements, a retirement or termination of employment by the CEO that is not initiated by the Company and that is caused by any one or more of the following events, in each case, without the CEO’s written consent: (i) a material reduction in his base salary or Target Bonus (as defined in the New CEO Agreement) opportunity; (ii) a material diminution in his title or authority, duties, reporting lines or responsibilities; (iii) a relocation of his principal place of employment by more than 50 miles; (iv) the CEO does not timely receive certain equity grants or awards specified in the New CEO Agreement; (v) failure of a successor to the Company to agree to assume and honor the agreement; or (vi) any other material breach of the agreement or any material compensation agreement by the Company or its affiliates. Additionally, “Good Reason” will only exist if the CEO provides written notice stating the Good Reason event, we do not cure such event, and the CEO terminates employment within a certain period of time after the end of the cure period.

During fiscal 2022, the Board held eight meetings, both in person and telephonically. Each member of the Board attended 75% or more of the total number of meetings of the Board and the total number of meetings held by all of the committees on which such director served during the director’s term in office during fiscal 2022. While our Corporate Governance Guidelines provide that Board members are expected to attend our Annual General Meeting, our 2022 AGM was held outside of our usual schedule for holding the AGM, due to our mid-year emergence from bankruptcy and appointment of a new Board of Directors upon emergence. As such, it was not practicable to engage in the usual advance AGM preparations and our Board members were not present in person at the AGM. In accordance with Irish law and our Articles of Association, the AGM was chaired by one of the proxyholders present appointed by the Corporate Secretary.
COMPENSATION OF EXECUTIVE OFFICERS
All of the foregoing severance compensation and benefits are subject to Mr. Olafsson’s execution and nonrevocation of a general release of claims against us and his continued compliance with restrictive covenants as described below.

The New CEO Agreement provides that Mr. Olafsson will be restricted from soliciting our employees and business partners during the 12-month period following his termination of employment for any reason (the “Restricted Period”). The New CEO Agreement also provides that Mr. Olafsson will be restricted from competing with us during the Restricted Period; provided that the Restricted Period will be reduced to six months for terminations that occur between January 1, 2025 and December 31, 2025, and shall not apply following Mr. Olafsson’s termination of employment if the date of termination is on or after January 1, 2026 or if Mr. Olafsson’s employment is terminated by the Company without Cause or by Mr. Olafsson with Good Reason.
As further described in our Current Report on Form 8-K filed February 2, 2024, we granted certain post-emergence equity awards to Mr. Olafsson, which are subject to the 2024 Plan and individual written award agreements. Such equity award agreements provide that, in the event of Mr. Olafsson’s termination of service as a result of death, disability or Normal Retirement, or by us without Cause or by Mr. Olafsson for Good Reason (each as defined in the 2024 Plan) other than in connection with a Change in Control (as defined in the 2024 Plan), Mr. Olafsson’s unvested RSUs will vest in full and Mr. Olafsson’s unvested PSUs will remain outstanding and will be eligible to vest and be settled based on our achievement of the performance targets, subject, in the case of Mr. Olafsson’s termination of employment without Cause or for Good Reason, to Mr. Olafsson signing and not revoking a release of claims. In the event of a termination by us without Cause or by Mr. Olafsson for Good Reason in connection with a Change in Control, awards will become fully vested and payable, subject to the Realized Value PSUs, which will be subject to achieving the relevant performance targets.
Mr. Reasons’ and Dr. Richardson’s Severance

Under each of the Prior CSO Agreement and the New CSO Agreement, in the event that Dr. Richardson’s employment is terminated by the Company without Cause or by Dr. Richardson with Good Reason, Dr. Richardson is entitled to the following severance compensation and benefits: (a) an amount equal to 1x (under the Prior CSO Agreement) and 1.5x (under the New CSO Agreement) the sum of his annual base salary and target annual bonus payable in installments; (b) a lump sum payment of a prorated target annual bonus with respect to the year in which the termination occurred; (c) a lump sum payment equal to 12 months of COBRA premiums that would have been payable by Dr. Richardson if he had elected to continue coverage under the Company’s health and welfare plans; and (d) our coverage of the cost of outplacement services for up to 12 months.

On November 14, 2023, in connection with our Emergence from the 2023 Bankruptcy Proceedings and the cancellation of all of our then-existing ordinary shares, all outstanding equity-based awards under the 2022 Plan were

PAY VERSUS PERFORMANCE
automatically cancelled without consideration and the 2022 Plan was of no further force and effect with respect to any equity-based awards thereunder. As a result, there were no outstanding equity awards at 2023 fiscal year-end.
The equity awards included above are comprised of PSUs, RSUs and stock options granted from 2016 through 2023. The following assumptions underpin the fair value calculations.
Fair values for PSUs subject to market-based measures such as Relative TSR have been calculated using a Monte Carlo valuation model. As a result of the cancellation of all of the outstanding PSUs in December 2020 due to none of the performance targets having potential to be met, no valuations were required for the 2021 measurement year. As a result of the cancellation of all of the outstanding PSUs following Emergence from the 2023 Bankruptcy Proceedings on November 14, 2023, no valuations were required for the 2023 measurement year. Fair values for stock options have been calculated using a Black-Scholes valuation model as of the relevant measurement date.
CAP and Financial Performance Measure
In accordance with SEC rules, the following are graphical comparisons of CAP and the financial performance measure, net income, shown in the pay versus performance table. The Company believes that there would not be a meaningful comparison in showing three years (2021, 2022 and 2023) of CAP compared to TSR as TSR only covers the period from June 17, 2022 through December 30, 2022, the period since the Company’s emergence from the 2020 Bankruptcy Proceedings during fiscal 2022.

COMPENSATION OF NON-EMPLOYEE DIRECTORS
[MISSING IMAGE: bc_oneonetinc-bw.jpg]
COMPENSATION OF NON-EMPLOYEE DIRECTORS
Fiscal 2022

As approved by our Board, the compensation structure for non-employee directors for fiscal 2022 up until our emergence from bankruptcy (“Emergence”) consisted of an annual cash retainer and supplemental cash retainers. Upon Emergence, our Board approved the compensation structure for non-employee directors as described in the section “Post-Emergence” below.
Pre-Emergence
The pre-Emergence compensation structure was determined in conjunction with the Governance and Compliance Committee, after reviewing data and analyses from the Governance and Compliance Committee’s independent compensation consultant prior to Emergence, Willis Towers Watson (“WTW”). For fiscal 2022, until our Emergence, non-employee directors received the compensation described below:
Cash Retainers
Board Members. Each director received an annual cash retainer of $336,000, paid in quarterly installments at the end of each quarter. Directors joining the Board other than on the first day of a quarter received a cash retainer pro-rated for the number of days served during their initial quarter of service.
Committee Chairs. The Chair of the Audit Committee received a supplemental annual cash retainer of $25,000. The Chair of the Human Resources and Compensation Committee received a supplemental annual cash retainer of $20,000. The Chairs of the Governance and Compliance Committee and the Science and Technology Committee each received a supplemental annual cash retainer of $15,000. The Chair of the Strategic Review Committee did not receive any additional retainer for this service.
Committee Members. Each member of a committee (excluding committee chairs) received a supplemental annual cash retainer of $5,000.
Non-Executive Chairman of the Board. Our non-executive Chairman received a supplemental annual cash retainer of $139,600.
Equity Awards
RSUs. Historically, at the time of our Annual General Meeting, each non-employee director received an annual grant of RSUs with a value of $295,000. Additionally, our non-executive Chairman received, at the time of our Annual General Meeting, additional RSUs with a value of $112,000. The awards vested on the date of our next succeeding Annual General Meeting.
New directors received a pro-rated annual equity grant. A pro-rated annual equity grant would not be granted to any new director who commenced service less than three months prior to the vesting date.
During fiscal 2020, our Board, upon the recommendation of the Governance and Compliance Committee and the HRCC, and with the advice of WTW, approved, in lieu of an annual equity award, an increase in the annual cash retainer for all directors by an amount equal to 80% of the annual equity award value, reflecting a 20% reduction to reflect the shorter-term nature of this component. This change was implemented due to the various uncertainties the Company was facing associated with outstanding legal issues related to opioids and Acthar® Gel, and was benchmarked against similar changes implemented at other companies facing such uncertainties and is generally aligned with the approach taken by companies of comparable size to the Company. This compensation structure was again approved in fiscal 2021, as the Company’s circumstances had not materially changed.
Other
Pursuant to our U.S. Matching Gift Program, we match employee and director contributions to eligible charitable organizations up to $2,500 per year. Directors are also reimbursed for reasonable out-of-pocket

COMPENSATION OF NON-EMPLOYEE DIRECTORS
expenses incurred in attending Board meetings, committee meetings and shareholder meetings. Directors are typically provided with commercial aircraft airfare in order to travel to and from such meetings.
Post-Emergence
Upon our Emergence on June 16, 2022, our Board approved the 2022 compensation for non-employee directors described below.
Cash Retainers
Board Members. Each non-employee director receives an annual cash retainer of $75,000, paid in quarterly installments at the beginning of each quarter.
Committee Chairs. The Chair of the Audit Committee receives a supplemental annual cash retainer of $25,000. The Chairs of the Human Resources and Compensation Committee and the Governance and Compliance Committee each receive a supplemental annual cash retainer of $17,500.
Committee Members. Each member of the Audit Committee (excluding the chair) receives a supplemental annual cash retainer of $15,000. Each member of the Human Resources and Compensation Committee and the Governance and Compliance Committee (excluding the chairs) receives a supplemental annual cash retainer of $10,500.
Non-Executive Chairman of the Board. The non-executive Chairman of the Board receives a supplemental annual cash retainer of $25,000.
In addition, each non-employee director will receive $1,500 for each meeting attended that is in excess of 10 meetings (including meetings of the Board and each committee of the Board).
Equity Awards
On June 16, 2022, the Board approved equity grants to each non-employee director of 48,809 RSUs (intended to have a $700,000 value based on a pre-Emergence valuation of the Company presented to the Board at such time) and a grant of 75,091 RSUs to our non-executive Chairman of the Board (intended to have a $930,000 value based on such valuation). The RSU grants were intended to represent the full equity compensation for our non-employee directors for the first two years following Emergence, and therefore vest ratably on each of the first two anniversaries of the date of our Emergence. The RSU grants became effective on July 1, 2022, by which time the OTC trading price of the Company’s ordinary shares exceeded the per share price based on the pre-Emergence valuation of the Company. It was subsequently determined that the RSU grants may have as a technical matter exceeded the annual grant maximum amount set forth in the MIP (as defined below) and that due to ministerial errors in computation, fewer units than intended to achieve the $700,000 valuation had been granted to each non-employee director, other than the non-executive Chairman, to whom more units than intended to achieve the $930,000 valuation had been granted. In order to remedy these errors, on August 16, 2022, each non-employee director agreed to relinquish 22,533 (44,354, in the case of the non-executive Chairman) of the previously granted RSUs (taken ratably from the two vesting tranches). Ms. Ling and Ms. Silbermann were not impacted by the errors, as they were appointed to the Board subsequent to the June 2022 grants.
In connection with their appointments to our Board effective August 12, 2022 and October 5, 2022, Ms. Ling and Ms. Silbermann each received a grant of 26,276 RSUs on September 14, 2022 and October 11, 2022, respectively. The RSUs vest ratably on each of the first two anniversaries of Emergence.
On January 3, 2023, we granted to each non-employee director 26,277 RSUs (39,083 RSUs, in the case of the non-executive Chairman), subject to the applicable director’s continued service through such date. The RSUs vest ratably on each of the first two anniversaries of Emergence.

COMPENSATION OF NON-EMPLOYEE DIRECTORS
Director Share Retention and Ownership Guidelines
Our Corporate Governance Guidelines have provisions requiring all non-employee directors to hold Mallinckrodt ordinary shares with a market value of at least five times the annual cash retainer. Until the required ownership level is achieved, the non-employee directors are required to retain net after tax shares received upon vesting of RSUs. However, as a result of the Chapter 11 Cases and related circumstances, on November 3, 2020, the Board waived compliance with the stock ownership guidelines for the duration of the Chapter 11 Cases. The stock ownership guidelines have been reinstated since our Emergence on June 16, 2022.
2022 Director Compensation
The following table provides information concerning the compensation paid by us to each of our non-employee directors for the fiscal year ended December 30, 2022. Compensation for Mark C. Trudeau, our former President and CEO, and Sigurdur O. Olafsson, our current President and CEO, are shown in the Summary Compensation Table. Neither Mr. Olafsson nor Mr. Trudeau received additional compensation for their services as a director.

COMPENSATION DISCUSSION AND ANALYSIS
This Compensation Discussion and Analysis (“CD&A”) describes our executive compensation philosophy and objectives and the decisions of the Human Resources and Compensation Committee (“HRCC”) of our Board of Directors (“Board”) regarding the fiscal 2022 compensation of our named executive officers (“NEOs”). This section provides details on both the pre-Emergence compensation programs and decisions made by the pre-Emergence HRCC and Board, as well as the compensation programs and decisions made by our post-Emergence HRCC and Board for fiscal 2022 compensation.
Fiscal 2022 Company Performance
Despite the various challenges of fiscal 2022, including our emergence from bankruptcy on June 16, 2022, the core operations of our business outperformed our expectations and we exceeded our Adjusted EBITDA guidance and achieved the high end of our net sales guidance for the year as we continued to focus on executing our three near-term strategic priorities: strengthening the balance sheet; stabilizing our portfolio; and making the right investments in our pipeline.
Key performance highlights for fiscal 2022 include:

Total net sales of $1.914 billion, including Specialty Brands net sales of $1.270 billion and Specialty Generics net sales of $644.8 million.

Cash balance at the end of the fiscal year end of $409.5 million.   The Company continues to maintain an undrawn accounts receivable financing facility up to $200 million, ending the fiscal year with approximately $610 million in liquidity.

Pipeline developments.   In September 2022, Terlivaz became the only treatment for adults with hepatorenal syndrome approved by the U.S. Food and Drug Administration (“FDA”). Since approval, we have been working to engage with hospitals to gain formulary inclusion of Terlivaz and are pleased with the formulary approval thus far in hospitals that have reviewed the product. With respect to INOmax Evolve, the next-generation delivery system of INOmax, we believe we remain on track for FDA approval in 2023.
Please refer to the more comprehensive discussions contained in our Annual Report on Form 10-K for the fiscal year ended December 30, 2022 for additional information about these highlights.
Executive Summary
We believe our executive compensation practices play a key role in driving our performance. These practices are designed to maximize shareholder value and return, and to reward performance when financial, operational and strategic performance goals that drive long-term value for our shareholders are achieved. Following Emergence and in connection with the Company’s ability to grant equity in 2022, we believe our compensation practices are heavily weighted toward long-term stock-based compensation and are designed to align the long-term interests of executives with those of our shareholders. By utilizing performance-based compensation as a significant portion of total compensation, actual realized compensation is accordingly expected to be higher when we overperform and lower when we underperform.

Dr. Romano departed the Executive Committee and Mallinckrodt on December 1, 2022.
Executive Compensation Philosophy
Our executive compensation philosophy, which was approved by the post-Emergence HRCC, provides a governance framework that is based on the tenets of sound judgment and discretion, including the following principles:

Compensation should strongly align the interests of executive officers with those of shareholders through the use of stock-based compensation and executive stock ownership;

Compensation policies and practices should support effective governance;

Focus on total compensation opportunity (base salary, annual incentive compensation and long-term incentive compensation) with an explicit role for each element;

Compensation should be competitive, but not excessive, in order to attract and retain talented executive officers who can achieve our long-term strategic goals and create shareholder value;

Compensation earned should be aligned with Company performance and investor returns;

Compensation should reward corporate and individual performance to encourage collaboration and collective interests, and recognize key contributors;

The reward elements should be balanced, with an emphasis on performance-based compensation;

Compensation goals and practices should be transparent and easy to communicate, both internally and externally;

Goal setting is a key activity and should be conducted in a rigorous manner resulting in targets that reflect challenging, yet achievable, levels of performance; and

Pay programs and oversight of these programs should avoid excessive compensation risk that could adversely impact the Company.
Fiscal 2022 Compensation Program
The following table summarizes the major elements of our fiscal 2022 executive compensation program and the objective of each element. They are designed to work together, as the HRCC views the executive compensation program as an integrated total compensation program. The overall value of compensation is compared to market data on compensation opportunities at pharmaceutical industry and peer companies to ensure that our executive pay programs are positioned competitively. The HRCC

30   MALLINCKRODT PUBLIC LIMITED COMPANY – Proxy Statement

COMPENSATION OF EXECUTIVE OFFICERS
considers the mix of variable and fixed compensation when determining base salary and short- and long-term incentives with an emphasis on variable compensation rather than fixed compensation.      
ElementKey FeaturesObjective
Base salaryFixed cash compensation.Offer a stable income, intended to reflect the market value of the executive’s role, with differentiation for strategic significance, individual capability and experience.
Annual incentive compensation
Market-competitive, performance-based cash bonus opportunity tied to achievement of Company goals.

Calculation for each executive’s cash incentive is based on performance versus pre-determined goals tied to financial performance measures.

Each executive’s individual performance can modify the amount received up to a maximum, provided that in 2022, any individuals who participated in the 2022 KEIP did not have an individual performance modifier.
Focus executives on pre-determined patient, employee and shareholder value objectives and drive specific behaviors that foster short- and long-term growth and profitability.
Long-term incentive compensation
Awards of performance units and restricted units

Performance units may be earned from 0% to 200% of the target number of units over a 2.5 year performance period*. For the second half of fiscal 2022 (July 2, 2022 through December 30,2022) through 2024 fiscal year end (December 27, 2024), half of the performance units are based on adjusted operating cash flow, while the other half are based on our Total Shareholder Return (“TSR”) versus TSR performance of the Russell 2000 Biotechnology Subsector Index, in each case over the performance period.

To the extent earned, performance units are delivered as ordinary shares after the end of the performance period except for any portion of the award earned above target, which is delivered as cash.

Restricted units vest in three equal annual installments on each anniversary of the NEO’s employment contract effective date or start date with the Company.
Align the interests of executives with the interests of shareholders in long-term growth and stock performance, reward executives for the achievement of multi-year performance objectives and shareholder value creation and promote retention.

Each unit is converted into one ordinary share at vesting.
Retention Bonuses
Cash-based retention bonus awarded in September 2020 to the NEOs who served on the Executive Committee prior to Emergence. These retention bonuses were subject to repayment in the event the award recipient resigned, retired, voluntarily terminated employment or was terminated by the Company for cause prior to May 15, 2022. The awards ceased to be subject to repayment on May 15, 2022. In addition, cash-based retention bonuses awarded in August 2020 and paid in May 2022 for a select group of non-executives.
Cash-based retention bonus awarded in 2022 to the NEOs who served on the Executive Committee prior to Emergence and remained employed directly following Emergence. Payment of the retention bonus was contingent upon remaining continuously employed with the Company through the 90-day anniversary of Emergence.
Designed to stabilize the executive leadership team and reduce the possibility of turnover.
No additional cash-based retention bonuses were awarded post-Emergence.
*
Performance period aligns with our financial quarterly and fiscal year dates. Therefore, fiscal 2022 second half period is July 2, 2022 through December 30, 2022, which is our fiscal 2022 third and fourth quarters. Our 2024 fiscal year end date is December 27, 2024.
Shareholder Engagement
It is and has been our practice for many years to engage with our investors on a routine basis as part of our investor relations program, during which the Company’s executives regularly meet with investors at both public conferences as well as in private meetings. Our engagement program focuses on overall performance of the business, particularly on subjects such as financial and commercial performance, research and development efforts, corporate strategy, capital allocation and business development, as well as corporate governance, social responsibility, executive compensation and other similar areas of interest.
We value our shareholders’ feedback and perspectives, and we are committed to continuing this broad scope of engagement with our shareholders across multiple channels, as we believe that the solicitation and consideration of shareholder views is a critical component of driving long-term value for the Company.
Compensation Decision-Making
Role of the HRCC and Management.
The HRCC reviews our executive compensation policies, practices and plans on an ongoing basis to determine whether they are consistent with our compensation philosophy and objectives, and whether they need to be modified in light of changes in our business or changes in the market. The HRCC meets periodically with management to review compensation policies and specific levels of compensation paid to officers and other key personnel and approves compensation and programs for executive officers other than our CEO. The HRCC reports to the Board on compensation paid to officers and other key

32   MALLINCKRODT PUBLIC LIMITED COMPANY – Proxy Statement

COMPENSATION OF EXECUTIVE OFFICERS
personnel and makes recommendations to the Board regarding CEO compensation. In addition, our CEO makes recommendations to the HRCC regarding salary adjustments and the setting of incentive targets and awards for executive officers other than himself.
In determining the compensation of an executive officer, the HRCC considers various factors, including:

Company, business unit and individual performance, as well as business conditions and our business outlook;

Market data on compensation opportunities of officers with similar responsibilities at comparable companies;

The officer’s experience, skillset, current and future responsibilities and potential contribution to our performance;

Retention considerations; and

Compensation levels of our executives with similar levels of responsibility.
Role of the Compensation Consultant.
The HRCC utilizes the services of independent compensation consultants from time to time and has the sole authority to retain, compensate and terminate any such compensation consultants. Prior to emergence from Chapter 11 in fiscal 2022, Willis Towers Watson Public Limited Company (“WTW”) served as the independent compensation consultant to the pre-Emergence HRCC. Upon emergence from Chapter 11 in fiscal 2022, Lyons, Benenson & Company Inc. (“LB&Co.”) served as the independent compensation consultant to the post-Emergence HRCC. LB&Co. reported directly to the HRCC, and within its scope of services, LB&Co. reviewed HRCC materials, attended all HRCC meetings, reviewed our peer group and competitive positioning of individual executives versus market, advised the HRCC with program design, provided advice to the HRCC as compensation issues arose and provided recommendations on certain specific aspects of our compensation programs. The HRCC assessed the independence of LB&Co. and determined that LB&Co. was independent and that no conflicts of interest existed during fiscal 2022.
Peer Group Determination.
Given the rapidly changing business landscape of the pharmaceutical industry, it is important for us to maintain a current view of peer competitors, including to be able to assess compensation opportunities for officers with similar responsibilities at comparable companies to ours. The HRCC periodically reviews the peer group it uses and approves changes, based on an established set of criteria and the recommendation of its independent compensation consultant. The peer group in place at the time of setting fiscal 2022 compensation (the “Pre-Emergence Peer Group”) was approved by our pre-Emergence HRCC prior to our 2021 bankruptcy filing. The specific companies were selected using objective size criteria, in a range that the HRCC determined is appropriate, as well as taking into consideration revenue and market capitalization, business similarity and our market for executive talent. We believe the peer group includes companies that we compete with for business, executive talent and/or investment dollars.
The following table sets forth the Pre-Emergence Peer Group.

Alkermes plc
Amneal Pharmaceuticals
BioMarin Pharmaceutical Inc.

In September 2022, the post-Emergence HRCC, with the assistance of LB&Co, analyzed this peer group to determine whether it should be revised. After consideration of various factors, the post-Emergence HRCC approved a new peer group to be used for 2023 compensation decisions.
Fiscal Year 2022 Executive Compensation Decisions
Given our bankruptcy proceedings, base salaries and target percentages under the AIP for our NEOs serving at the beginning of the year were unchanged from 2021 levels. As discussed below, the pre-Emergence HRCC established the annual performance targets under the AIP at the beginning of 2022.
Post-Emergence, the post-Emergence HRCC established base salaries for our then-serving and newly appointed NEOs, as well as affirmed or established opportunities under our AIP and 2022 KEIP. The post-Emergence HRCC reviewed, with support of LB&Co., the Company’s strategy and operating performance and key objectives for the remainder of the fiscal year. In addition, the post-Emergence HRCC looked at the potential impact of current and emerging external factors such as the dynamic competitive landscape for executive talent, a review of compensation data and market trends from the peer group and external surveys. Finally, the post-Emergence HRCC weighed internal factors specific to Mallinckrodt such as executive experience, role and individual capabilities. Actions taken by the post-Emergence HRCC considered the Company’s operating plan for the remainder of fiscal 2022 and the then-current share price and were calculated to align management and shareholder interests through competitive performance-based compensation that attracted, motivated and retained important talent.
Base Salary
The HRCC evaluates base salaries annually as well as upon a promotion or other change in job responsibility to determine if increases are appropriate. The post-Emergence HRCC, based in part upon the recommendation of our CEO and considering each NEO’s level of responsibility, skillset and experience, as well as market data for similar positions at companies in our peer group and issues of internal pay equity, approved the base salary amounts and increases detailed in the table below.
In consultation with the pre-Emergence HRCC, the pre-Emergence Board froze the base salary for Mr. Trudeau in consideration of Company performance. In addition, base salaries for Dr. Romano and Mr. O’Neill were unchanged during fiscal 2022.

Fiscal 2022 Short-Term Incentive Awards
2022 Annual Incentive Plan
For fiscal 2022, the NEOs that participated in the AIP were Mr. Olafsson, Mr. Reasons and Ms. Nielsen. Mr. Tyndall and Mr. Welch did not participate in the AIP but instead continued to participate in the Company’s 2022 KEIP, which they were participating in prior to their elevation to being executive officers. The 2022 KEIP is further discussed below. Mr. Trudeau, Dr. Romano and Mr. O’Neill were originally participants in the AIP, but their 2022 short-term incentive payouts were determined in accordance with their respective separation agreements entered into in connection with the termination of their employments. For more information on the payments these NEOs received in connection with the termination of their employments, see the section titled “Mr. Trudeau, Dr. Romano and Mr. O’Neill’s Termination Benefits” below.
The HRCC established award targets for each of the NEOs participating in the AIP that were expressed as a percentage of base salary. The table below shows the opportunities for Mr. Olafsson, Mr. Reasons and Ms. Nielsen.
2022 Annual Incentive Plan Target as a % of Salary
Sigurdur Olafsson135%
Bryan Reasons75%
Henriette Nielsen75%
The AIP provides each of the participants with the opportunity to receive an annual incentive payment determined by multiplying their annual incentive target by the Company’s achievement against pre-determined financial performance targets and then by an individual performance modifier. The Company performance targets were designed to be achieved in a range from 0% (achievement at less than threshold) to 150% (achievement at maximum or above) of target based upon our performance, subject to an individual performance modifier that can also be applied in a range from 0% to 150%, with

MALLINCKRODT PUBLIC LIMITED COMPANY – Proxy Statement   35

COMPENSATION OF EXECUTIVE OFFICERS
a cap on the total target opportunity as set by each executive’s respective employment agreement, based on which a cap of 250% of base salary was set for Mr. Olafsson and a cap of 150% of base salary was set for Mr. Reasons and Ms. Nielsen, respectively. The following illustrates the formula for the AIP:
[MISSING IMAGE: fc_annual-bw.jpg]
2022 AIP Performance Measures.   For the 2022 AIP, the pre-Emergence HRCC approved the incentive plan and established the Company performance measures. For fiscal 2022, the Company performance measures were based upon adjusted EBITDA, adjusted operating cash flow and net sales. The pre-Emergence HRCC believed these measures were key drivers of the longer term value creation and key indicators of the current and future strength of our business.

Adjusted EBITDA was defined as earnings for the fiscal year before interest, taxes, depreciation and amortization, adjusted to exclude incremental Terlivaz launch spend contingent upon FDA approval, impact from foreign currency rate volatility, discretionary bonuses for non-executives as approved by the HRCC, and the sale of an intellectual property research and development asset.

Adjusted operating cash flow represented operating cash flow prepared in accordance with GAAP adjusted for separation costs, reorganization advisor fees, working capital impacts related to the CARES Act, significant legal and environmental charges, working capital impacts resulting from the Company’s Chapter 11 bankruptcy filing, severance costs, interest payments, acquisition/divestiture costs, incremental Terlivaz launch spend contingent upon FDA approval, and the impact of a customer bankruptcy.

Adjusted net sales represented net sales calculated in accordance with GAAP, excluding foreign currency exchange rate impacts.
The weighted average funding for the 2022 AIP was designed to range from 0% to 150% of target based upon our performance against these measures. The HRCC maintains discretionary authority to further modify the funding, both negatively and positively, based on the HRCC’s evaluation of Company achievement against the strategic imperatives, as further discussed below. The following chart summarizes the 2022 AIP design with respect to the Company performance measures, including the relative weighting, performance targets, actual results and weighted average funding for our participating NEOs.

Strategic Imperatives.   In addition to performance against financial measures, the HRCC also considers Company performance that supported the accomplishment of pre-determined key strategic imperatives and has the ability to adjust the overall size of the AIP awards, both negatively and positively. This allows the HRCC to decrease or increase the size of the awards if, in the HRCC’s opinion, such amounts are not appropriately earned or adequately reflect performance.

2022 AIP Achievement and Payout.   Following the conclusion of fiscal 2022, the post-Emergence HRCC determined the level of achievement and amount of payouts to which our NEOs were entitled under the AIP. The post-Emergence HRCC assessed the performance against the Company performance measures and the Company’s progress toward each of the strategic imperatives, and it received input from our CEO on each of the NEOs (other than our CEO) regarding individual performance and key contributions made in fiscal 2022. The Board and post-Emergence HRCC respectively determined that a payout at the 106% level based on Company performance and a 150% individual performance modifier for Mr. Olafsson and Ms. Nielsen and a 130% individual performance modifier for Mr. Reasons were appropriate.

2022 Key Employee Incentive Plan
Mr. Tyndall and Mr. Welch, each of whom were appointed as members of the Executive Committee for the first time in fiscal 2022, participated in the 2022 KEIP.
The pre-Emergence HRCC approved the 2022 KEIP, which was a component of our pre-Emergence Stock and Incentive Plan and included two separate stand-alone performance periods (the first half (“First Half”) and the second half of fiscal 2022 (“Second Half”)).
Award target amounts under the 2022 KEIP for Mr. Tyndall and Mr. Welch were not established by the HRCC as they were not serving as executive officers at the time. Their award targets were set by the former Chief Legal Officer. The 2022 KEIP replaced the Company’s short- and long-term incentive plans and as such the full year target amounts for the NEOs were equal to the sum of their annual incentive targets and a portion of their long-term equity incentive targets, as shown in the tables below.
2022 Full Year Target KEIP Opportunity
Mark Tyndall$690,710
Stephen Welch$535,500
Performance Periods and Measures.   The 2022 KEIP consisted of two standalone performance periods: the First Half (50% of award) and the Second Half (50% of award). The pre-Emergence HRCC determined that two semi-annual performance periods and semi-annual goals placed a greater

COMPENSATION OF EXECUTIVE OFFICERS
emphasis on the Company’s objectives and the corresponding results we needed to achieve throughout the year. In addition, this type of incentive plan structure is aligned with market practice for companies operating under similar circumstances as us during Chapter 11 proceedings.
The performance measures for each period were separately determined and were based for each period on adjusted EBITDA and adjusted operating cash flow, weighted 60% and 40%, respectively. These performance measures were set in relation to our annual budget for the enterprise as approved by the pre-Emergence Board. The pre-Emergence HRCC viewed these measures as key drivers to preserve and maximize enterprise value and maximize cash generation during bankruptcy and a period of significant litigation.

Adjusted EBITDA was defined as earnings for the fiscal year before interest, taxes, depreciation and amortization, adjusted to exclude incremental Terlivaz launch spend contingent upon FDA approval, impact from foreign currency rate volatility, discretionary bonuses for non-executives as approved by the HRCC, and the sale of an intellectual property research and development asset.

Adjusted operating cash flow represented operating cash flow prepared in accordance with GAAP adjusted for separation costs, reorganization advisor fees, working capital impacts related to the CARES Act, significant legal and environmental charges, working capital impacts resulting from the Company’s Chapter 11 bankruptcy filing, severance costs, interest payments, acquisition/divestiture costs, incremental Terlivaz launch spend contingent upon FDA approval, and the impact of a customer bankruptcy.
The weighted average funding for the 2022 KEIP was designed to range from 0% to 150% of target based upon our performance against these measures for each standalone performance period. The HRCC maintained discretionary authority to further modify the funding, both negatively and positively.
The following charts summarize the 2022 KEIP design with respect to the Company performance measures for each of the First Half and Second Half, including the relative weighting, performance targets, actual results and weighted average funding for our participating NEOs. As shown in the charts, fiscal 2022 First Half performance resulted in an overall weighted average funding of 124% and the Second Half performance resulted in an overall weighted average funding of 95%.

Strategic Imperatives.   In addition to performance against financial and operational measures, the HRCC also considered Company performance that supported the accomplishment of the Company’s strategic imperatives (as disclosed in the table “Fiscal 2022 Strategic Imperatives” above) and had the ability to adjust the overall size of the executive bonuses, both negatively and positively.

2022 KEIP Achievement and Payout.   For fiscal 2022, the HRCC determined the amount payable to our NEOs under the 2022 KEIP by multiplying the NEO’s individual incentive target by the funding based on Company performance for the two performance periods. The pre-Emergence HRCC approved the First Half payments and the post-Emergence HRCC approved the Second Half payments.
The HRCC also took into account the progress on the strategic imperatives and challenges that faced the business in fiscal 2022 when determining the 2022 KEIP award payouts for each of the two performance periods. The following charts show the HRCC approved multipliers for each of the two performance periods. The 2022 KEIP did not include an individual performance modifier and the evaluation of the strategic imperatives did not result in an increase or decrease to the amounts earned.

2022 Grants
During 2022, our NEOs, except for Mr. Trudeau, Dr. Romano and Mr. O’Neill, each of whom separated from the Company in 2022, received a one-time equity award (the “Initial Grant”) under the Company’s 2022 Stock and Incentive Plan (the “MIP”) which consisted of a mix of performance units (weighted 50%) and restricted units (weighted 50%), pursuant to the NEOs’ employment agreements. The table below sets forth the Initial Grant with respect to long-term incentive compensation for equity grants made during fiscal 2022.

Performance units.   We grant performance units to create incentives for executives to achieve long-term performance goals aligned with our multi-year business strategies. Performance units represent unissued ordinary shares; we do not issue ordinary shares until the applicable performance-based vesting requirements are satisfied. The vesting requirements for performance units granted to NEOs during fiscal 2022 were based upon adjusted operating cash flow and relative TSR targets, each

40   MALLINCKRODT PUBLIC LIMITED COMPANY – Proxy Statement

COMPENSATION OF EXECUTIVE OFFICERS
weighted at 50%, over a performance period of second half of fiscal 2022 to fiscal year end 2024 (July 2, 2022 through December 27, 2024).

Adjusted Operating Cash Flow for the Company will be calculated for second half of fiscal 2022 through fiscal year end 2024 (July 2, 2022 through December 27, 2024) and is defined as net cash from operating activities of continuing operations for the performance cycle, excluding the following items: payments related to the Company’s emergence from bankruptcy, CARES Act refunds, interest payments, opioid and DOJ and CMS settlements, impact of acquisitions and divestitures, and any unusual or nonrecurring items that may be approved by the HRCC or Board. We have not disclosed the specific non-GAAP operating cash flow targets as they are confidential and disclosure could lead to competitive harm.

Relative TSR means our total shareholder return as compared to the Russell 2000 Biotechnology Subsector index. This group of companies is broader than the peer group of companies used for competitive comparisons of executive compensation, and it includes some companies that are much larger or smaller than Mallinckrodt. The HRCC believes that use of a larger comparison group for measuring our TSR better reflects our market performance against the broad industry, even though some of the companies in the performance group would not be reasonable comparators for the compensation peer group because of extreme differences in size. The HRCC periodically reviews our TSR comparison group and approves changes taking into account the recommendation of the HRCC’s independent advisor. The HRCC believes that relative TSR measure provides a “total picture” of our performance and balances the achievement of absolute internal goals (Adjusted Operating Cash Flow) with relative performance against an index in a measure that is directly linked with long-term shareholder value creation. The multiplier used to determine the number of earned performance units could be between a threshold of 50% and a maximum of 200%, with threshold achievement corresponding to a relative TSR level at the 25th percentile (below which no performance units are earned) and maximum an achievement level corresponding to a relative TSR level at the 75th percentile.
Restricted units.   We grant restricted units to align the interests of management and shareholders and to promote retention of key talent over the vesting period. Restricted units represent unissued ordinary shares; we do not issue ordinary shares until the applicable vesting requirements are satisfied. When the vesting requirements are satisfied, the executive receives ordinary shares without restriction, subject to the Company’s share ownership requirements. Restricted units granted to NEOs during fiscal 2022 vest one-third annually beginning on the first anniversary of either the NEOs employment agreement effective date or hire date with the Company in 2022.
Executive Retention Bonus Program
In November 2019, the pre-Emergence HRCC approved a key executive retention plan, also known as the Executive Retention Bonus Program (“ERBP”) for specified employees, including the NEOs employed at that time, and the pre-Emergence Board approved an ERBP for our former CEO, Mr. Trudeau. The ERBP provided a cash-based retention bonus award to specified employees of the Company. In August 2020, the pre-Emergence HRCC approved an extension of the ERBP for a small number of employees, including the NEOs employed at that time, Mr. Reasons, Dr. Romano and Mr. O’Neill, and the pre-Emergence Board approved an extension for Mr. Trudeau. The pre-Emergence HRCC considered the challenges facing the Company, including the opioid litigation, and both the pre-Emergence Board and the pre-Emergence HRCC believed it critical to continue to stabilize the executive leadership team and reduce the possibility of further turnover during a critical time at the Company. Further turnover would have resulted in the loss of expert knowledge, slowed momentum and could have impaired the Company’s ability to continue to navigate the challenges, including the opioid litigation, and bring pipeline products to market. The pre-Emergence HRCC consulted WTW on the extension of the program and approaches utilized by other companies facing similar uncertainties for retention of executives in determining the value of the extended ERBP. The pre-Emergence HRCC (and the pre-Emergence

MALLINCKRODT PUBLIC LIMITED COMPANY – Proxy Statement   41

COMPENSATION OF EXECUTIVE OFFICERS
Board with regard to Mr. Trudeau) approved awards under the extended ERBP for the NEOs employed at that time in the following amounts.
2020 Executive Retention Bonuses
Mark C. Trudeau$1,575,000
Bryan M. Reasons$900,000
Steven J. Romano, M.D.$930,000
Hugh M. O’Neill$930,000
Awards under the extended 2020 ERBP were subject to repayment in the event the award recipient resigned, retired, voluntarily terminated employment or was terminated by the Company for cause prior to May 15, 2022. The awards ceased to be subject to repayment on May 15, 2022.
In 2022, the post-Emergence HRCC approved cash-based retention bonuses awarded to the NEOs who served on the Executive Committee prior to Emergence and remained employed directly following Emergence. Payment of the retention bonus was contingent upon remaining continuously employed with the Company through the 90-day anniversary of Emergence.
Other Benefits
We provide NEOs the same benefits that are provided to all employees, including defined contribution retirement benefits and health and welfare benefits. In addition, our executive officers are provided with certain additional benefits, intended to be competitive with the practices of our peer companies.
Retirement Benefits.   The NEOs are eligible to participate in our Retirement Savings and Investment Plan (“Mallinckrodt Retirement Savings Plan”), which is our 401(k) plan available to all eligible U.S. employees, and our Supplemental Savings and Retirement Plan (“Mallinckrodt Supplemental Savings Plan”), our non-qualified deferred compensation plan in which executive officers and other senior employees may participate. The Mallinckrodt Supplemental Savings Plan is a so-called “excess” plan that extends the 401(k) benefits beyond the Internal Revenue Code (the “Code”) limitations.
Under the Mallinckrodt Retirement Savings Plan, we make an automatic contribution of 3% of an employee’s eligible pay, irrespective of whether the employee contributes to such plan. Additionally, we match $0.50 for every dollar employees contribute, up to the first 8% of eligible pay.
Mallinckrodt Supplemental Savings Plan.   Under the Mallinckrodt Supplemental Savings Plan, participants, including NEOs, may defer up to 50% of their base salary and 75% of their annual bonus. We provide matching credits based on the participant’s deferred base salary and bonus at the same rate that such participant is eligible to receive matching contributions under the Mallinckrodt Retirement Savings Plan and Company credits on any cash compensation (i.e., base and bonus) that the participant earns during a calendar year in excess of applicable IRS limits ($305,000 for 2022). Participants are fully vested in matching and Company credits (including earnings on such credits) upon completion of two years of service. The Mallinckrodt Supplemental Savings Plan is a non-qualified deferred compensation plan that is maintained as an unfunded “top-hat” plan and is designed to comply with Section 409A of the Code. Amounts credited to the Mallinckrodt Supplemental Savings Plan as participant deferrals or Company credits may also be credited with earnings (or losses) based upon investment selections made by each participant from investments that generally mirror investments offered under the Mallinckrodt Retirement Savings Plan. Participants may elect whether they will receive a distribution of their Mallinckrodt Supplemental Savings Plan account balances upon termination of employment or at a specified date. Distributions can be made in a lump sum or in up to 15 annual installments. Elective deferrals of compensation were suspended for fiscal year 2022.
International Assignment Benefits.   We seek to ensure that employees who are sent on an assignment outside of their home country are not subject to a higher income tax liability than they would have paid in their home country pursuant to our tax equalization program. Each such employee is responsible for a theoretical home income tax liability based on an estimate of his or her anticipated home income tax liability, and we are responsible for any home country and assignment country taxes in excess of that

42   MALLINCKRODT PUBLIC LIMITED COMPANY – Proxy Statement

COMPENSATION OF EXECUTIVE OFFICERS
amount. We deduct hypothetical income taxes from the employee’s compensation during the tax year and pay any assignment country taxes on his or her behalf.
Health and Welfare Benefits.   The health and welfare benefits we provide to the NEOs are offered to all eligible U.S. based employees and include medical, dental, prescription drug, vision, life insurance, accidental death and dismemberment, business travel accident, personal and family accident, flexible spending accounts, short- and long-term disability coverage and an employee assistance program.
Additional Benefits.   We maintain an executive physical examination program and an executive financial and tax planning program for executive officers. These programs are intended to encourage executives to proactively manage their health and complex financial/tax situations, thereby enabling them to focus on the business. The benefits are periodically assessed against market data from comparable companies and intended to be competitive for our industry. In addition, when we request a spouse or partner to attend a business meeting, such as our annual national sales recognition program for top performers, we reimburse executive officers for expenses related to this travel and for the income taxes associated with these travel expenses.
Employment Agreements.   For each of Mr. Trudeau, Dr. Romano and Mr. O’Neill, our NEOs who separated from the Company in 2022, we entered into separation agreements that were intended to codify into a contractual arrangement the severance benefits that they otherwise would have been entitled to under our executive severance plan.
The disbursement of severance pay and related benefits during the pendency of the Chapter 11 Cases was subject to, among other things, approval by the Bankruptcy Court and the restrictions regarding severance payments imposed by section 503(c) of Chapter 11 of the United States Code. For detailed information on the severance benefits provided under the employment agreements and severance actually paid pursuant to certain related separation agreements, see the section entitled “Potential Payments upon Termination” below.
Share Ownership Requirements
The pre-Emergence Board established share ownership requirements that required executive officers to hold equity with a value expressed as a multiple of their base salary, with the CEO set at five times base salary and all other executive officers set at three times base salary, with certain allowances for including awarded but unvested equity grants in the calculations. On November 3, 2020, the pre-Emergence Board of Directors waived compliance with the stock ownership requirements for the duration of the Chapter 11 Cases. The stock ownership guidelines were subsequently reinstated by the post-Emergence Board following Emergence.
Anti-Hedging/Anti-Pledging Policy
Our Insider Trading Policy prohibits directors, officers and employees from entering into or trading in puts, calls, cashless collars, options or similar rights and obligations or any other hedging activity involving our securities, other than the exercise of a Company-issued stock option.
Our policy also prohibits directors, officers and employees from purchasing our securities on margin, borrowing against our securities held in a margin account or pledging our securities as collateral for a loan. However, an exception may be granted by our Chief Legal Officer if the individual clearly demonstrates the financial capacity to repay the loan without resort to the pledged securities.
Executive Financial Recoupment Program (“Clawback”)
Since the Company’s separation from Covidien plc in 2013, the Corporate Governance Guidelines have mandated that the Company have a Board-approved policy for recoupment of incentive compensation. This policy was originally implemented by the Board in 2014 and was most recently amended in 2022 in connection with the Company’s corporate integrity agreement entered into with the Office of Inspector General of the Department of Health and Human Services. Mallinckrodt’s policy states that in the event of an accounting restatement resulting from material non-compliance with financial reporting requirements under applicable law, the Board or, if so designated by the Board, the

MALLINCKRODT PUBLIC LIMITED COMPANY – Proxy Statement   43

COMPENSATION OF EXECUTIVE OFFICERS
HRCC, is authorized to recover any incentive compensation that was overpaid taking into account such factors as the Board or the HRCC deems appropriate. In addition, Mallinckrodt’s policy states that in the event of certain events of significant misconduct, including a violation of law or regulation or a significant violation of a Company policy, to the extent permitted by law, the Company must seek to recoup cash awards and all or a portion of the cash awards or the realized value of equity awards for the three year period prior to the recoupment determination.
Under Mallinckrodt’s policy, the Company agreed to disclose annually whether, at any time during the last completed fiscal year, the Board required recoupment or forfeiture of any incentive compensation received by certain employees, including NEOs, (1) if required by law, and (2) if not required by law, so long as the disclosure (a) would not violate any individual’s privacy rights, (b) is not likely to result in or exacerbate any existing or threatened employee, shareholder or other litigation, arbitration, investigation or proceeding against the Company and (c) is not otherwise prohibited. Subject to the exceptions described in the previous sentence, if any such recoupment or forfeiture under the policy occurred, we are required to disclose the general circumstances of the recoupment and/or forfeiture, and if no such recoupment or forfeiture occurred during the last completed fiscal year, we are required to disclose that no such event occurred.
In 2022, there was no recoupment or forfeiture applied to the incentive compensation of any executive officer of the Company.
2022 Say-on-Pay Vote
We consider the views of our shareholders in designing our executive compensation program and value feedback on our compensation practices. At our 2022 Annual Meeting of Shareholders, approximately 81% of the votes cast on our annual advisory vote on the compensation of our NEOs were in favor of this proposal. We believe that the level of support received for this proposal affirms our approach to executive compensation. See page 74 for this year’s say-on-pay proposal.
Compensation Committee Interlocks and Insider Participation
The directors who served on the HRCC during fiscal year 2022 were Mr. Goldman (Chair), Mr. El-Dada, Ms. Ling, Dr. Myers and Mr. Sulat (members of the post-Emergence HRCC) and Mr. Norton (Chair), Mr. Carlucci, Mr. Carroll and Ms. Whitaker (members of the pre-Emergence HRCC). During the 2022 fiscal year, there were no members of the HRCC who were officers or employees of the Company or any of its subsidiaries, were formerly officers of the Company, or had any relationship otherwise requiring disclosure hereunder.

EXECUTIVE COMPENSATION TABLES
The information presented in the Summary Compensation Table reflects compensation for our NEOs for fiscal 2022. In connection with our Emergence from bankruptcy, each existing equity interest in Mallinckrodt, including our ordinary shares and existing equity-based awards, was cancelled and extinguished, and our shareholders did not receive any recovery upon our emergence from Chapter 11 proceedings. Accordingly, upon Emergence, our NEOs who were employed by the Company prior to filing Chapter 11 did not receive any value for their RSUs, stock options or any other equity interest in Mallinckrodt held prior to Emergence.

Employment Agreements
Employment Agreement with Mr. Olafsson.   Upon our emergence from Chapter 11 proceedings on June 16, 2022, we entered into an employment agreement (as subsequently amended and restated on February 22, 2023, the “New CEO Employment Agreement”) with Mr. Olafsson, pursuant to which Mr. Olafsson commenced service as our CEO effective as of June 25, 2022 (the “Start Date”), for an indefinite term.
Pursuant to the New CEO Employment Agreement, Mr. Olafsson receives an annual base salary of $1,100,000. Mr. Olafsson will also be eligible to receive a performance-based annual bonus with a target amount of 135% of base salary and a maximum amount of 250% of base salary. For the 2022 annual bonus, Mr. Olafsson will receive a guaranteed amount of $742,500. In addition, the New CEO Employment Agreement provided that on or within 30 calendar days following the Start Date, Mr. Olafsson would be granted a one-time equity award (the “Initial Grant”) covering 450,545 Ordinary Shares, 50% of which would consist of restricted units that vest ratably on each of the first three anniversaries of the Start Date, and the remaining 50% of which would consist of performance units that cliff vest following the performance period that ends on December 27, 2024 as outlined on the applicable award agreement, based equally on the Company’s attainment of (1) total shareholder return relative to the TSR generated by the Russell 2000 Biotechnology Subsector index (or another peer group of pharmaceutical companies selected by the HRCC) peers and (2) adjusted operating cash flow, each during the performance period. Beginning in fiscal year 2023 and for each subsequent fiscal year, Mr. Olafsson will be eligible to receive equity awards (the “Annual Grant”) under our equity compensation plans including the MIP (as defined below). The target value for the Annual Grant in respect of fiscal year 2023 will be not less than $4,000,000.
The New CEO Employment Agreement provides that Mr. Olafsson will be restricted from competing with us and from soliciting our employees and business partners during the 12-month period following his termination of employment for any reason. For information on termination benefits under the New CEO Employment Agreement, see “Potential Payments Upon Termination” on page 52 below.
Other NEO Employment Agreements.   We entered into employment agreements with each of Mr. Reasons, Ms. Nielsen, Mr. Tyndall and Mr. Welch on August 17, 2022 (the “Effective Date”), each of which were subsequently amended and restated on February 22, 2023. Pursuant to their employment agreements, Mr. Reasons, Ms. Nielsen, Mr. Tyndall and Mr. Welch receive annual base salaries of $630,000, $620,000, $575,000 and $450,000, respectively. Each of the executives are eligible to receive a performance-based annual bonus with a target amount of 75% of base salary and a maximum amount of 150% of base salary, except for Mr. Welch, who will be eligible for a performance-based bonus with a target of 60% of base salary and a maximum of 120% of base salary. In addition, the employment agreements provide that as soon as reasonably practicable following the Effective Date, the executives would be granted one-time equity awards (each, an “Initial Grant”) consisting of 225,273 (for Mr. Reasons), 150,182 (for Ms. Nielsen and Mr. Tyndall) and 75,091 (for Mr. Welch) ordinary shares, 50% of which would consist of restricted units that vest ratably on each of the first three anniversaries of the Effective Date, and the remaining 50% of which would consist of performance units that cliff vest following the performance period that ends on December 27, 2024 as outlined in the applicable award agreement based on the Company’s attainment of TSR relative to the TSR generated

by the Russell 2000 Biotechnology Subsector index (or another peer group of pharmaceutical companies selected by the HRCC) during the performance period. The employment agreements also provide that beginning in fiscal year 2023, and for each subsequent fiscal year, each of the executives will be eligible to receive equity awards under our equity compensation plans. For additional information on termination benefits under the employment agreements, see “Potential Payments Upon Termination” on page 52 below.
Former Officer Employment Agreements.   We entered into employment agreements with each of Mr. Trudeau, Dr. Romano and Mr. O’Neill on July 20, 2020. The term of each employment agreement was three years, with automatic one year renewals, absent notice of non-renewal. Pursuant to Mr. Trudeau’s employment agreement, he was entitled to (i) a base salary of $1,050,000, (ii) an annual bonus with a target annual bonus opportunity not less than 125% of his annual base salary, (iii) eligibility for participation in the welfare and other benefit plans, practices, policies and programs for senior executives of the Company generally, and (iv) reimbursement for all reasonable, documented business expenses incurred in accordance with performance of Mr. Trudeau’s duties under the agreement. For each of Dr. Romano and Mr. O’Neill, pursuant to their respective employment agreements, each executive was entitled to (i) a base salary of $620,000, (ii) an annual bonus with a target annual bonus opportunity not less than 65% of his annual base salary, (iii) eligibility for participation in the welfare and other benefit plans, practices, policies and programs for senior executives of the Company generally, and (iv) reimbursement for all reasonable, documented business expenses incurred in accordance with performance of such executive’s duties under the agreement. Each employment agreement also provided for severance benefits which were intended to codify into a contractual arrangement the severance benefits that each executive officer was already entitled to under the executive severance plan.
The employment agreements with each of Mr. O’Neill and Dr. Romano were supplemented by a letter agreement entered into upon our emergence from Chapter 11 proceedings on June 16, 2022, which provided that the applicable officer agrees to remain continuously employed with us and our subsidiaries and affiliates through the 90-day anniversary of Emergence. During such period, the executives continued to receive compensation and benefits in accordance with the terms of his employment agreement. Upon the expiration of such period and for fifteen days thereafter, each executive had the option to terminate his employment and receive the severance benefits provided under his employment agreement upon an involuntary termination of employment, subject to conditions in his employment agreement, including his execution and nonrevocation of a release of claims. In consideration for his agreement to remain employed through the end of the 90-day period, each executive was entitled to be paid an additional amount equal to three times his monthly base salary, which amount would also be paid if his employment is terminated without cause by us prior to the end of the 90-day period.
In connection with each of Mr. Trudeau, Dr. Romano and Mr. O’Neill’s terminations of employment, each executive entered into a Separation of Employment and General Release that set forth applicable severance payments to be paid in connection with such executive’s termination. See “Potential Payments Upon Termination” on page 52 below for more information.

The following table provides information regarding outstanding stock option awards and unvested restricted unit and performance unit awards held by each NEO and the corresponding market value as of December 30, 2022, except for Mr. Trudeau, Dr. Romano and Mr. O’Neill, each of whom did not have any outstanding equity awards at fiscal year end.

EXECUTIVE COMPENSATION TABLES
(1)
The amounts reported include amounts that we credited to our Supplemental Savings Plan on behalf of the NEOs during fiscal 2022. These amounts are included in the amounts set forth in the All Other Compensation column of the Summary Compensation Table for fiscal 2022.
(2)
The amounts reported include earnings credited to the NEO’s account in the Supplemental Savings Plan. Earnings on amounts credited to the Supplemental Savings Plan are determined by investment selections made by each NEO in investment alternatives that generally mirror investment choices offered under the Retirement Savings Plan (our 401(k) plan).
(3)
The amounts reported for each NEO includes the NEO’s total balance in our Supplemental Savings Plan as of December 30, 2022.
Mallinckrodt Supplemental Savings Plan.   Under the Mallinckrodt Supplemental Savings Plan, participants, including NEOs, may defer up to 50% of their base salary and 75% of their annual bonus. We provide matching credits based on the participant’s deferred base salary and bonus at the same rate that such participant is eligible to receive matching contributions under the Mallinckrodt Retirement Savings Plan and Company credits on any cash compensation (i.e., base salary and bonus) that the participant earns during a calendar year in excess of applicable IRS limits ($305,000 for 2022). Participants are fully vested in matching and Company credits (including earnings on such credits) upon completion of two years of service. The Mallinckrodt Supplemental Savings Plan is a non-qualified deferred compensation plan that is maintained as an unfunded “top-hat” plan and is designed to comply with Section 409A of the Code. Amounts credited to the Mallinckrodt Supplemental Savings Plan as participant deferrals or Company credits may also be credited with earnings (or losses) based upon investment selections made by each participant from investments that generally mirror investments offered under the Mallinckrodt Retirement Savings Plan. Participants may elect whether they will receive a distribution of their Mallinckrodt Supplemental Savings Plan account balances upon termination of employment or at a specified date. Distributions can be made in a lump sum or in up to 15 annual installments. Elective deferrals of compensation were suspended for 2022.
Under the Mallinckrodt Retirement Savings Plan, we make an automatic contribution of 3% of an employee’s eligible pay, irrespective of whether the employee contributes to such plan. Additionally, we match $0.50 for every one dollar $1.00 employees contribute, up to the first 8% of eligible pay.
Potential Payments upon Termination
Employment Agreements.   The following description of severance provisions of Employment Agreements (which are further described above on page 49) describes the terms as in effect on December 30, 2022, which excludes Mr. Trudeau, Dr. Romano and Mr. O’Neill, each of whom separated from the Company during fiscal 2022, and whose termination benefits are described below. The following description does not apply to Mr. Olafsson’s termination benefits, which are further described in the section “Mr. Olafsson’s Severance” below.
For the NEOs employed by the Company as of December 30, 2022, severance benefits are payable pursuant to employment agreements entered into between each of the NEOs and a subsidiary of the Company (the “Employment Agreements”). Under the Employment Agreements, benefits are payable to the NEOs, upon termination without cause or voluntary termination with Good Reason. Post-termination benefits consist of:

Payment of 1 times (1.5x for our CFO) the executive’s annual base salary and annual target bonus payable in installments;

A lump sum payment equal to a prorated portion of the target bonus payable with respect to the year in which the termination occurs;

A lump sum payment equal to 12 months (18 months for our CFO) of premiums that would have been payable by the NEO if the NEO had elected to continue coverage under the Company’s health and welfare plans pursuant to the Consolidated Omnibus Budget Reconciliation Act of 1985 (“COBRA”);

Accelerated vesting in full of the Initial Grant RSUs;

A pro-rata vesting of Initial Grant PSUs to vest at the completion of the performance period based on certified performance results; and

52   MALLINCKRODT PUBLIC LIMITED COMPANY – Proxy Statement

EXECUTIVE COMPENSATION TABLES

Outplacement services for up to 12 months.
In addition, change in control severance benefits are payable to eligible executives, including NEOs, only if the double-trigger requirements are satisfied, meaning that, in order to receive any of the following benefits, the executive must experience an involuntary termination of employment or good reason resignation during a period that begins upon, and ends 1 year after, a change in control. Post-termination benefits consist of:

Payment of 1 times (1.5x for our CFO) the executive’s annual base salary and annual target bonus payable as a lump sum;

A lump sum payment equal to a prorated portion of the target bonus payable with respect to the year in which the termination occurs;

A lump sum payment equal to 12 months (18 months for our CFO) of premiums that would have been payable by the NEO if the NEO had elected to continue coverage under the Company’s health and welfare plans under COBRA;

Accelerated vesting in full of RSUs, PSUs and other equity awards with the vesting level of PSUs based on assumed attainment of TSR at the target performance level; and

Outplacement services for up to 12 months.
The payment of benefits under the Employment Agreements is conditioned upon the executive executing a general release in favor of us and is subject to the terms of the Non-Competition, Non-Solicitation and Confidentiality Agreement by and between the executive and us, under which the executive agreed not to disclose confidential information of the Company at any time and not to compete with us nor solicit our employees or customers, for a period of one year following termination of employment. We may cancel benefits that are payable or seek to recover benefits previously paid if the executive does not comply with these provisions or violates the release of claims. Payments may be delayed until six months after termination of employment if necessary to comply with Section 409A of the Code.
Upon a termination of employment for cause, executives, including NEOs, are not eligible for severance benefits under the Employment Agreements and forfeit all unvested RSUs and PSUs. In addition, the RSUs and PSUs include a “clawback” feature pursuant to which we may recover the amount of any profit the NEO realized upon the vesting of RSUs or PSUs for a period of three years from the determination that a recoupment is required, to the extent permitted by law.
For purposes of the Employment Agreements, “cause” means: substantial refusal of the NEO to perform the duties and responsibilities of the NEO’s job as required by the Company other than due to permanent disability, a material violation of any fiduciary duty or duty of loyalty owed to us; conviction of misdemeanor (other than a traffic offense) or felony; fraud, embezzlement or theft; violation of a material rule or policy, including a violation of our Guide to Business Conduct; or unauthorized disclosure of any of our trade secrets or confidential information.
For purposes of the Employment Agreements, “good reason” means a retirement or termination of employment by the NEO that is not initiated by the Company and that is caused by any one or more of the following events, in each case, without the NEO’s written consent : (i) the Company requires the NEO to relocate to a principal place of employment more than fifty miles from the NEO’s existing place of employment, which materially increases the NEO’s commuting time; (ii) the Company, without the NEO’s consent, materially reduces the NEO’s base salary or target annual bonus opportunity, other than a reduction of less than 10% that is made at the same time to the base salary or target annual bonus opportunity, as applicable, of all similarly situated employees; (iii) or a requirement that the NEO report to any other person, position or entity other than the CEO. Additionally, “good reason” will only exist if the NEO provides written notice stating the good reason event, we do not cure such event, and the NEO terminates employment within a certain period of time after the end of the cure period.
Mr. Olafsson’s Severance.   Under the New CEO Employment Agreement, in the event that Mr. Olafsson’s employment is terminated by us without Cause or by Mr. Olafsson with good reason (in

MALLINCKRODT PUBLIC LIMITED COMPANY – Proxy Statement   53

EXECUTIVE COMPENSATION TABLES
each case as defined in the New CEO Employment Agreement), Mr. Olafsson will be entitled to the following severance compensation and benefits (the “Severance Benefits”): (a) an amount equal to two times the sum of his annual base salary and target annual bonus payable in installments, (b) a lump sum payment of a prorated target annual bonus with respect to the year in which the termination occurs, (c) our payment of COBRA premiums for 18 months or until he becomes eligible for comparable benefits through a new employment, (d) accelerated vesting of outstanding equity awards by an additional 12 months following the termination, except that (i) the Initial Grant will vest in full and (ii) the pro rata portion of PSUs (other than PSUs covered by the Initial Grant) will remain eligible to vest at the end of the performance period and will be settled based on certified performance results, and (e) our coverage of the cost of outplacement services for up to 12 months.
In the event that Mr. Olafsson’s employment is terminated by us without Cause or by Mr. Olafsson with good reason during the period beginning 120 days prior to and ending 24 months after a Change in Control (in each case as defined in the New CEO Employment Agreement), Mr. Olafsson will receive the foregoing Severance Benefits with the following enhancements: (a) the base salary and bonus severance will be a lump sum payment of 2.5 times the sum of his annual base salary and target annual bonus, and (b) all outstanding equity awards will become vested (with PSUs being settled based on the greater of target and actual performance through the Change in Control).
For purposes of the New CEO Employment Agreement, as well as the “clawback” feature discussed above, “cause” means: (i) substantial refusal of the CEO to perform the duties and responsibilities of his job as required by the Board other than due to incapacity; (ii) a material violation of any fiduciary duty or duty of loyalty owed to us; (iii) conviction of misdemeanor (other than a traffic offense) involving moral turpitude or felony; (iv) any willful act or omission of fraud, embezzlement or theft; (v) any violation of a material rule or policy, including a violation of our Guide to Business Conduct; or (vi) any unauthorized disclosure of any of our trade secrets or confidential information.
For purposes of the New CEO Employment Agreement, “good reason” means a retirement or termination of employment by the CEO that is not initiated by the Company and that is caused by any one or more of the following events, in each case, without the CEO’s written consent: (i) a material reduction in his base salary; (ii) a material diminution in his title or authority, duties, reporting lines or responsibilities; (iii) a relocation of his principal place of employment by more than 50 miles; (iv) the Company’s failure to timely make certain equity grants specified in the agreement; (v) failure of a successor to the Company to agree to assume and honor the agreement; or (vi) any other material breach of the agreement or any material compensation agreement by the Company. Additionally, “good reason” will only exist if the CEO provides written notice stating the good reason event, we do not cure such event, and the CEO terminates employment within a certain period of time after the end of the cure period.
All of the foregoing severance compensation and benefits are subject to Mr. Olafsson’s execution and nonrevocation of a general release of claims against us and his continued compliance with restrictive covenants as described below.
Other Termination Benefits.   The terms of our 2022 AIP and 2022 KEIP and equity plan provide for certain benefits upon a NEO’s termination of employment due to death, disability or retirement. For this purpose, normal retirement occurs where an executive officer terminates employment after attaining age 60 and the sum of the executive’s age and years of service equals at least 70. Under the 2022 AIP and 2022 KEIP, NEOs are eligible to receive a pro-rated incentive cash award based on the number of days that the executive officer was employed by us during the fiscal year upon death, disability or normal retirement. Under the equity plan as in effect on December 30, 2022, NEOs were eligible to receive full vesting of RSUs and PSUs upon death, disability or normal retirement.
The table below reflects the amount of compensation that would become payable to each of our NEOs, other than Mr. Trudeau, Dr. Romano and Mr. O’Neill, under existing employment agreements and plans if the NEO’s employment had terminated on December 30, 2022, the last day of fiscal 2022, given the NEO’s service levels as of such date and, where applicable, based on our closing stock price as of that date, which was $7.45. These benefits are in addition to benefits available prior to the occurrence of any termination of employment, including benefits available generally to salaried employees, such as distributions under the Retirement Savings Plan.

EXECUTIVE COMPENSATION TABLES
The actual amounts that would be paid upon an NEO’s termination of employment or in connection with a change in control can be determined only at the time of any such event. Due to a number of factors that may affect the amount of any benefits provided upon the events discussed below, actual amounts paid or distributed may be higher or lower than indicated in the table. Factors that could affect these amounts include the timing during the year of any such event, our stock price, the executive’s age and years of service, the attained level of performance for performance units and any additional agreements or arrangements we may enter into in connection with any change in control or termination of employment.

Each NEO’s employment agreement provides for full acceleration of the RSU portion of the Initial Grant in the event of termination without cause or for good reason. With respect to his outstanding PSUs, Mr. Olafsson would receive full acceleration. The other NEOs would receive a pro-rata portion of their outstanding PSUs until the second anniversary of the applicable grant date, and the pro-rated PSUs would continue to be subject to performance vesting conditions. For purpose of this analysis, PSU value assumes payout at target performance, prorated for employment period through the change in control date.

PAY RATIO
As required by the Dodd-Frank Wall Street Reform and Consumer Protection Act, we are presenting the ratio of our CEO’s annual total compensation to our median employee’s annual total compensation.
As permitted under the SEC rules, we used annual gross wages as reported in our payroll system as our consistently applied compensation measure to determine our median employee. We maintained the same determination date as reported in prior years of October 1 to determine our employee workforce. We annualized pay for those who commenced work during the twelve month period wages were considered. We identified employees who were paid within a 2% range of the median. We selected an employee from that group and determined that person’s total compensation was $104,032. Our CEO, Mr. Olafsson became our President and CEO effective June 25, 2022. Accordingly, based on Mr. Olafsson’s annualized total compensation of $8,284,242, our ratio of CEO pay to median worker pay for 2022 is approximately 80:1. This ratio was determined using reasonable estimates as permitted by the SEC’s rules and should not be used as a comparison with pay ratios disclosed by other companies.

The disclosure included in this section is prescribed by SEC rules and does not necessarily align with how the Company or the HRCC views the link between the Company’s performance and its NEO’s pay. For a discussion of how the Company views its executive compensation structure, including alignment with Company performance, see the CD&A beginning on page 27.
In accordance with SEC rules, the following table and supporting narrative contain information regarding compensation actually paid (“CAP”). Neither CAP nor the amount reported in the Summary Compensation Table (“SCT”) reflect the amount of compensation actually paid, earned or received during the applicable year. Per SEC rules, CAP was calculated by adjusting SCT total compensation values for the applicable year as described in the footnotes to the following table.
The HRCC did not consider the pay versus performance data presented below in making its pay decisions for any of the years shown.

Assumes a hypothetical initial investment of $100 in new ordinary shares issued on June 17, 2022. Peer Group used for total shareholder return (“TSR”) comparisons reflects NYSE Pharmaceutical Index, which is the same industry index included in Part II, Item 5, “Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities,” furnished on pages 60-61 of the Company’s Annual Report on Form 10-K for the fiscal year ended December 30, 2022. The 2022 TSR covers the period from June 17, 2022 through December 30, 2022, reflecting the period of time since Company’s emergence from Chapter 11 proceedings.

SEC rules require us to designate a “company-selected measure” that in our assessment represents the most important financial performance measure (other than total shareholder return, stock price, or net income) used by the Company to link the CAP of our NEOs, for the most recently completed fiscal year, to our performance. For 2022, we selected adjusted operating cash flow. For 2020, the adjusted operating cash flow measure that we used for compensation purposes did include interest payments, but these amounts were excluded in this measure in 2021 and 2022. For consistency, adjusted operating cash flow for 2020 in the table above excludes the $268 million in interest payments. This performance measure may not have been the most important financial performance measure for years 2021 and 2020, and we may determine a different financial performance measure to be the most important financial performance measure in future years. Adjusted operating cash flow is a non-GAAP measure, and it represents operating cash flow prepared in accordance with GAAP adjusted for separation costs, reorganization advisor fees, working capital impacts related to the CARES Act, significant legal and environmental charges, working capital impacts resulting from the Company’s Chapter 11 bankruptcy filing, severance costs, interest payments, acquisition/divestiture costs, incremental Terlivaz launch spend contingent upon FDA approval and the impact of a customer bankruptcy.

The equity awards included above are comprised of PSUs, RSUs and stock options granted from 2016 through 2022. The following assumptions underpin the fair value calculations.
Fair values for PSUs subject to market-based measures such as relative TSR have been calculated using a Monte Carlo valuation model. As a result of the cancellation of all of the outstanding PSUs in December 2020, no valuations were required for the 2021 measurement year. Fair values for stock options have been calculated using a Black-Scholes valuation model as of the relevant measurement date.
List of Company Performance Measures
The following table lists the measures we believe are most important in linking CAP to Company performance during 2022.The order of the measures in this chart should not be interpreted as a ranking. Further details on these measures and how they feature in our compensation plans can be found in the CD&A section of this proxy statement.

CAP and Financial Performance Measures
In accordance with SEC rules, the following are graphical comparisons of CAP and the financial performance measures as shown in the pay versus performance table. The Company believes that there would not be a meaningful comparison in showing three years (2020, 2021 and 2022) of CAP compared to TSR as TSR only covers the period from June 17, 2022 through December 30, 2022, the period since the Company’s emergence from Chapter 11 proceedings.

AUDIT AND AUDIT COMMITTEE MATTERS
Audit Committee Report
As more fully described in its charter, which is available on our website, ir.mallinckrodt.com/corporate-governance/highlights, the Audit Committee oversees Mallinckrodt’s financial reporting process on behalf of the Board. Management has day-to-day responsibility for the Company’s financial reporting process, including assuring that the Company develops and maintains adequate financial controls and procedures and monitoring and assessing compliance with those controls and procedures, including internal control over financial reporting. Mallinckrodt’s independent auditors are responsible for auditing the annual consolidated financial statements prepared by management, expressing an opinion as to whether those financial statements fairly present the financial position, results of operations and cash flows of the Company in conformity with accounting principles generally accepted in the United States and discussing with the Audit Committee any issues they believe should be raised. The independent auditors are also responsible to the Audit Committee and the Board for testing the financial accounting and reporting control systems, for issuing a report on the Company’s internal control over financial reporting and for such other matters as the Audit Committee and Board determine.
In the performance of its oversight function, the Audit Committee has reviewed and discussed with management, the internal auditors and the independent auditors the consolidated financial statements for the fiscal year ended December 30, 202229, 2023 filed with the SEC. Management represented to the Audit Committee that these consolidated financial statements were prepared in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”). In addition, the Audit Committee has:


Discussed with the independent auditors the matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board (“PCAOB”) and the SEC;


Received from the independent auditors the written disclosures and letter required by the applicable requirements of the PCAOB regarding the independent auditors’ communications with the Audit Committee concerning independence;


Discussed with the independent auditors their independence from the Company and its management; and


Considered whether the independent auditors’ provision of non-audit services to the Company is compatible with maintaining the auditors’ independence.
Based upon the review and discussions referred to above, the Audit Committee recommended to the Board of Directors that Mallinckrodt’s audited consolidated financial statements prepared in accordance with U.S. GAAP be included in its Annual Report on Form 10-K for the fiscal year ended December 30, 202229, 2023 and filed with the SEC.
In connection with the appointment, remuneration, retention and oversight of the independent auditor, the Audit Committee annually reviews the qualifications, performance and independence of the independent auditor, and lead engagement partner, and assures the regular rotation of the lead engagement partner as required. In doing so, the Audit Committee considers a number of factors including, but not limited to quality of services provided, technical expertise and knowledge of the industry, effective communication, objectivity and the likely impact of changing the independent auditor. The Audit Committee also considers whether the non-audit services provided by Deloitte & Touche LLP are compatible with maintaining Deloitte’s independence.
The Audit Committee has appointed, subject to the advisory non-binding vote of our shareholders, Deloitte as our independent auditor for the fiscal year 2023.

PROPOSAL 3: ADVISORY NON-BINDING VOTE TO APPROVE THE COMPANY’S EXECUTIVE COMPENSATION
As described in the Compensation of Executive Officers section, the Human Resources and Compensation Committee’s goal in setting executive compensation is to provide a compensation package that attracts, motivates and retains executive talent and rewards executive officers for superior Company and individual performance while encouraging behavior that is in the long-term best interests of Mallinckrodt and its shareholders. Consistent with this philosophy, a significant portion of the total compensation opportunity for each of our executives is performance-based and dependent upon our achievement of specified financial goals and the performance of our shares on a long-term basis.
Shareholders are urged to read the Compensation Discussion & Analysisof Executive Officers section of this annual proxy statement,Proxy Statement, which discusses our compensation policies, as well as the Compensation of Executive Officers, Summary Compensation Table and other related compensation tables and narrative disclosure that describe the compensation of our named executive officers during fiscal 2022.2023. The Human Resources and Compensation Committee and the Board of Directors believe that Mallinckrodt’s compensation policies and procedures are effective in implementing our compensation philosophy and in achieving its goals and that the compensation of our named executive officers during fiscal 20222023 reflects and supports these compensation policies and procedures.
As required by the Dodd-Frank Wall Street Reform and Consumer Protection Act (Section 14a of the Securities Exchange Act), shareholders will be asked at the 20232024 Annual General Meeting to approve the following advisory resolution:
RESOLVED, that the compensation of the Company’s named executive officers described in the Compensation Discussion & Analysis and Compensation of Executive Officers sectionssection of the Proxy Statement and disclosed in the Summary Compensation Table, related compensation tables and narrative disclosure included in this Proxy Statement is approved.

PROPOSAL 4: AUTHORIZE THE COMPANY AND/OR ANY SUBSIDIARY OF THE COMPANY TO MAKE MARKET PURCHASES OR OVERSEAS MARKET PURCHASES OF COMPANY SHARES
Under Irish law, neither we nor any of our subsidiaries may make market purchases or overseas market purchases of our ordinary shares without shareholder approval. Accordingly, shareholders are being asked to authorize us, or any of our subsidiaries, to make market purchases or overseas market purchases of up to 10% of our issued shares. If adopted, this authority will expire at the close of business on March 29, 2024 unless renewed at the Annual General Meeting in 2023; accordingly we expect to propose renewal of this authorization at subsequent annual general meetings. Such purchases would be made only at price levels that the Board of Directors considers to be in the best interests of the shareholders generally, after taking into account our overall financial position.
Whether or not this proposed resolution is passed, we will retain the ability to effect repurchases as redemptions pursuant to our Articles of Association, although our subsidiaries are not able to effect market purchases in this manner. To date, our existing share repurchase program has been effected as redemptions pursuant to our Articles of Association.
In order for us or any of our subsidiaries to make market purchases or overseas market purchases of our ordinary shares, such shares must be purchased on a “recognized stock exchange”. This authority will therefore not be utilized unless the ordinary shares of Mallinckrodt are re-listed and trade on a recognized stock exchange under Irish law, such as the NYSE. The general authority, if approved by our shareholders, will become effective from the date of passing of the authorizing resolution.
Ordinary Resolution
The text of the resolution in respect of Proposal 4 is as follows:
RESOLVED, that the Company and any subsidiary of the Company are hereby generally authorized to make market purchases or overseas market purchases of ordinary shares in the Company (“shares”) on such terms and conditions and in such manner as the Board of Directors of the Company may determine from time to time, but subject to the provisions of the Companies Act 2014 and the following provisions:
(a)
The maximum number of shares authorized to be acquired by the Company and/or any subsidiary of the Company pursuant to this resolution shall not exceed, in the aggregate, 1,317,093 ordinary shares of US$0.01 each (which represents 10% of the Company’s issued ordinary shares as of our 2022 fiscal year end).
(b)
The maximum price to be paid for any ordinary share shall be an amount equal to 110% of the closing price on the relevant stock exchange on which the ordinary shares are listed (such as the NYSE American) for the ordinary shares on the trading day preceding the day on which the relevant share is purchased by the Company or the relevant subsidiary of the Company, and the minimum price to be paid for any ordinary share shall be the nominal value of such share.
(c)
This general authority will be effective from the date of passing of this resolution and will expire eighteen months from the date of the passing of this resolution, unless previously varied, revoked or renewed by ordinary resolution in accordance with the provisions of section 1074 of the Companies Act 2014. The Company or any such subsidiary may, before such expiry, enter into a contract for the purchase of shares which would or might be executed wholly or partly after such expiry and may complete any such contract as if the authority conferred hereby had not expired.
Unless otherwise instructed, the proxies will vote “FOR” this resolution.

PROPOSAL 5: AUTHORIZE THE PRICE RANGE AT WHICH THE COMPANY CAN RE-ALLOT SHARES HELD AS TREASURY SHARES
We may, from time to time, re-allot shares purchased by us and not cancelled (“treasury shares”) in connection with our executive compensation program, our employee stock purchase plan and our other compensation programs.
Under Irish company law, our shareholders must authorize the price range at which we may re-allot any shares held in treasury. In this proposal, that price range is expressed as a minimum and maximum percentage of the prevailing market price (as defined below). Under Irish law, this authorization expires after eighteen months unless renewed; accordingly, we expect to propose renewal of this authorization at subsequent annual general meetings.
The authority being sought from shareholders provides that the minimum and maximum prices at which an ordinary share held in treasury may be re-alloted are 95% and 120%, respectively, of the average closing price per ordinary share, as reported by a recognized stock exchange on which the ordinary shares are listed, for the thirty (30) trading days immediately preceding the proposed date of re-allotment. If an ordinary share is being re-allotted to satisfy an obligation under an employees’ share scheme, the minimum price at which such share may be re-allotted will be the nominal value of such share. Any re-allotment of treasury shares will be at price levels that the Board of Directors considers in the best interests of our shareholders. This authority will not be utilized unless the ordinary shares of Mallinckrodt are re-listed and trade on a recognized stock exchange under Irish law, such as the NYSE American. The general authority, if approved by our shareholders, will become effective from the date of passing of the authorizing resolution.
The affirmative vote of at least 75% of the votes cast, either in person or by proxy, at the 2023 Annual General Meeting is required to approve Proposal 5.
Special Resolution
The text of the resolution in respect of Proposal 5 is as follows:
RESOLVED, that as a special resolution, the re-allotment price range at which any treasury shares held by the Company may be re-alloted (including by way of re-allotment off-market) shall be as follows:
(a)
The maximum price at which such treasury share may be re-alloted shall be an amount equal to 120% of the “market price”;
(b)
The minimum price at which a treasury share may be re-alloted shall be the nominal value of the share where such a share is required to satisfy an obligation under an employees��� share scheme operated by the Company or, in all other cases, an amount equal to 95% of the “market price”; and
(c)
For the purposes of this resolution, the “market price” shall mean the average closing price per ordinary share of the Company, as reported by a recognized stock exchange on which the ordinary shares of Mallinckrodt plc are listed, for the thirty (30) trading days immediately preceding the proposed date of re-issuance.
FURTHER RESOLVED, that this authority to re-allot treasury shares shall expire at eighteen months after the date of the passing of this resolution unless previously varied or renewed in accordance with the provisions of Sections 109 and/or 1078 (as applicable) of the Companies Act 2014 (and/or any corresponding provision of any amended or replacement legislation) and is without prejudice or limitation to any other authority of the Company to re-allot treasury shares on-market.
