Exhibit 1.01


Conflict Minerals Report




Mallinckrodt plc is a global business consisting of multiple wholly owned subsidiaries (collectively, “Mallinckrodt” or “the Company”) that develop, manufacture, market and distribute specialty pharmaceutical products and therapies. The Company’s Specialty Brands reportable segment’s areas of focus include autoimmune and rare diseases in specialty areas like neurology, rheumatology, hepatology, nephrology, pulmonology and ophthalmology and oncology; immunotherapy and neonatal respiratory critical care therapies; analgesics; cultured skin substitutes and gastrointestinal products. Its Specialty Generics reportable segment includes specialty generic drugs and active pharmaceutical ingredients.


This Conflict Minerals Report (“CMR”) for the year ended December 31, 2022 (“the Reporting Period”) is presented to comply with Rule 13p-1 under the Securities Exchange Act of 1934 (“the Rule”). The Rule imposes certain reporting obligations on U.S. Securities and Exchange Commission (“SEC”) issuers whose manufactured products contain certain minerals which are necessary to the functionality or production of their products. These minerals are cassiterite, columbite-tantalite (coltan), gold, wolframite, and their derivatives, which are limited to tin, tantalum and tungsten (“3TG(s)” or “Conflict Minerals”). The Rule focuses on 3TG emanating from the Democratic Republic of the Congo (“DRC”) region and nine adjoining countries (together, the “Covered Countries”). If an issuer has reason to believe that any of the Conflict Minerals in their supply chain may have originated in the Covered Countries, or if they are unable to determine the country of origin of those Conflict Minerals, then the issuer must exercise due diligence on the Conflict Minerals’ source and chain of custody and submit a CMR to the SEC that includes a description of those due diligence measures.


This CMR relates to the process undertaken for Mallinckrodt products that were manufactured, or contracted to be manufactured, during the Reporting Period and that contain Conflict Minerals. The Company's policy with respect to the sourcing of conflict minerals (the “Conflict Minerals Policy”) can be found on its website at http://www.mallinckrodt.com/about/partnering/suppliers/conflict-minerals-policy/.


Executive Summary


Mallinckrodt performed a Reasonable Country of Origin Inquiry (“RCOI”) on suppliers believed to provide Mallinckrodt with materials or components containing 3TGs that are necessary to the manufacture of Mallinckrodt’s medical device products. None of the Company’s pharmaceutical medicines, biologic products or active pharmaceutical ingredients contain Conflict Minerals. Mallinckrodt’s suppliers identified 350 valid smelters and refineries (“smelters”), of which Mallinckrodt identified 49 as sourcing (or there was reason to believe they may be sourcing) from the Covered Countries. Mallinckrodt’s due diligence review indicated that 36 of these smelters have been audited and are conformant to the Responsible Minerals Assurance Process (“RMAP”). The remaining 13 smelters were subject to Mallinckrodt’s risk mitigation process according to the Organisation for Economic Co-operation and Development (“OECD”) Due Diligence Guidance for Responsible Supply Chain of Minerals from Conflict-Affected and High-Risk Areas (“OECD Due Diligence Guidance”).





Company Management Systems


Mallinckrodt’s strong management systems were established according to Step 1 of the OECD Due Diligence Guidance. Mallinckrodt’s management systems included:


Step 1A - Adopted, and clearly communicated to suppliers and the public, a company policy for the supply chain of minerals originating from conflict-affected and high-risk areas:

Implemented a Conflict Minerals policy;

Policy made publicly available at http://www.mallinckrodt.com/about/partnering/suppliers/conflict-minerals-policy/ ; and

Policy communicated directly to suppliers as part of RCOI process.

Step 1B - Structured internal management to support supply chain due diligence.

Maintained an internal cross functional team to support supply chain due diligence;

Appointed a member of the senior staff with the necessary competence, knowledge, and experience to oversee supply chain due diligence; and

Applied the resources necessary to support the operation and monitoring of these processes including internal resources and external consulting support.

Step 1C - Established a system of transparency, information collection and control over the supply chain:

Implemented a process to collect required supplier and smelter RCOI and due diligence data. Full details on the supply chain data gathering are included in the RCOI and Due Diligence sections of this CMR.

Step 1D - Strengthened company engagement with suppliers:

Directly engaged suppliers during RCOI process;

Reviewed supplier responses as part of RCOI process; and

Implemented a plan to improve the quantity and quality of supplier and smelter responses year over year.

Step 1E - Established a company and/or mine level grievance mechanism:

Recognized the RMAP’s three audit protocols for 3TG as valid sources of smelter or mine level grievances; and

Utilized Mallinckrodt’s ethics violations reporting system which allows employees to voice confidentially, without any fear of retribution, any concerns of potential violations of the Company’s Conflict Minerals Policy.


Reasonable Country of Origin Inquiry (RCOI)


Mallinckrodt designed its RCOI process in accordance with Step 2A and 2B of the OECD Due Diligence Guidance. Mallinckrodt’s RCOI process involved two stages:


Stage 1 - Supplier RCOI (Step 2A of the OECD Due Diligence Guidance)

Stage 2 - Smelter RCOI (Step 2B of the OECD Due Diligence Guidance)





Supplier RCOI


Mallinckrodt designed its supplier RCOI process to identify, to the best of its efforts, the smelters in Mallinckrodt’s supply chain in accordance with Step 2A of the OECD Due Diligence Guidance. Mallinckrodt’s supplier RCOI process for the Reporting Period included the following:


Developing a list of suppliers providing 3TG containing components to Mallinckrodt;

Contacting each supplier and requesting them to complete the industry standard Conflict Minerals Reporting Template (“CMRT”) including smelter information;

Reviewing supplier responses for accuracy and completeness;

Amalgamating supplier-provided smelters into a single unique list of smelters meeting the definition of a smelter under one of three industry recognized audit protocols; and

Reviewing the final smelter list (and comparing it to industry peers) to determine if Mallinckrodt reasonably identified all of the smelters in its supply chain.


For the Reporting Period, Mallinckrodt’s RCOI process was executed by Claigan Environmental Inc. (“Claigan”).


Mallinckrodt’s suppliers identified 350 smelters in their supply chain. The specific list of smelters is included in the Smelter and Refineries section at the end of this CMR.


Smelter RCOI


Due to the overlap between smelter RCOI and smelter due diligence, the smelter RCOI process is summarized in the Due Diligence section of this CMR.


Due Diligence


Mallinckrodt’s “Due Diligence Process” was designed in accordance with the applicable sections of Steps 2, 3, and 4 of the OECD Due Diligence Guidance.


Smelter RCOI and Due Diligence


Mallinckrodt’s smelter RCOI and Due Diligence Process were designed to:


Identify the scope of the risk assessment of the mineral supply chain (OECD Step 2B);

Assess whether the smelters/refiners have carried out all elements of due diligence for responsible supply chains of minerals from conflict-affected and high-risk areas (OECD Step 2C); and

Where necessary, carry out, including through participation in industry-driven programs, joint spot checks at the mineral smelter’s own facilities (OECD Step 2D).





Mallinckrodt’s smelter RCOI and Due Diligence Process included the following:


For each smelter identified in Mallinckrodt’s supply chain:

Mallinckrodt attempted direct engagement with the smelter to determine whether or not the smelter sources from the Covered Countries; and

For smelters that declared directly (e.g., email correspondence, publicly available Conflict Minerals policy, or information available on their website) or through their relevant industry association that they did not source from the Covered Countries, but were not recognized as conflict-free by the RMAP, Mallinckrodt reviewed publicly available information to determine if there was any contrary evidence to the smelter’s declaration. The sources reviewed included:

Public internet search of the facility in combination with each of the Covered Countries;

Review of specific non-governmental organization (“NGO”) publications. NGO publications reviewed included:

Enough Project

Global Witness

Southern Africa Resource Watch

Radio Okapi

The most recent United Nations Group of Experts report on the DRC.

For smelters that did not respond to direct engagement, Mallinckrodt reviewed publicly available sources to determine if there was any reason to believe that the smelter may have sourced from the Covered Countries during the Reporting Period.

Mallinckrodt reviewed the same sources as those used to compare against smelter sourcing declarations.

For high-risk smelters (smelters that are sourcing from, or there is reason to believe may be sourcing from, the Covered Countries and are not currently conformant to the RMAP), Mallinckrodt communicates the risk to senior management (OECD Step 3A) and may conduct risk mitigation as appropriate on the smelter according to OECD Step 3B.


For the Reporting Period, Mallinckrodt’s smelter RCOI and Due Diligence Process was executed by Claigan.


Mallinckrodt’s suppliers identified 350 smelters. Mallinckrodt identified 49 smelters that source, or there is reason to believe they may source, from the Covered Countries.


Mallinckrodt determined that 36 of these 49 smelters have been audited and are conformant to the RMAP, as of May 23, 2023.





Risk Mitigation


Mallinckrodt is committed to conducting risk mitigation on the 13 smelters that were not recognized as conformant to the RMAP. Mallinckrodt’s risk mitigation was designed in accordance with Step 3B of the OECD Due Diligence Guidance and was reported to designated senior management in accordance with Step 3A of the OECD Due Diligence Guidance. Mallinckrodt’s risk mitigation process included the following:


Additional due diligence to determine if there was any reason to believe the smelter directly or indirectly finances or benefits armed groups in the Covered Countries;

Verification with internal stakeholders and relevant suppliers of whether 3TGs from the specific smelter were actually in Mallinckrodt’s supply chain during the Reporting Period; and

Direct engagement with each high-risk smelter to verify risk and to encourage the smelter to become conflict-free.


Risk mitigation was required for 13 smelters verified by suppliers likely to be in Mallinckrodt’s supply chain. All 13 smelters came into Mallinckrodt’s supply chain through 25 suppliers, involving a small number of parts.


Improvement Plan


Mallinckrodt strives to improve the due diligence conducted to further mitigate risk that the necessary conflict minerals in Mallinckrodt’s products could directly or indirectly benefit or finance armed groups in the Covered Countries and will continue to take the following steps:


a.Incorporate a Conflict Minerals clause into new and renewing supplier contracts;

b.Encourage Mallinckrodt suppliers to obtain current, accurate, and complete information about the smelters in their respective supply chains;

c.Request smelters sourcing from the Covered Countries to be audited and certified to a protocol recognized by the RMAP; and

d.Evaluate opportunities to encourage the 25 suppliers to remove the 13 non-conformant smelters from their supply chain or attempt to identify alternate suppliers.


Mallinckrodt has provided information as of the date of this report. Subsequent events, such as the inability or unwillingness of any suppliers or smelters to comply with Mallinckrodt’s Conflict Minerals Policy, may affect the Company’s future determinations under the Rule.


Website addresses are included in this CMR for reference only. Any information contained on Mallinckrodt’s website is not incorporated by reference into this CMR.
