Exhibit 1.01
Conflict Minerals Report


Mallinckrodt plc is a global business consisting of multiple wholly owned subsidiaries (collectively, “Mallinckrodt” or “the Company”) that develops, manufactures, markets and distributes 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, nephrology, pulmonology and ophthalmology; immunotherapy and neonatal respiratory critical care therapies; analgesics and gastrointestinal products. Its Specialty Generics reportable segment includes specialty generic drugs and active pharmaceutical ingredients.

This Conflict Minerals Report (“CMR”) for the reporting period of January 1 through December 31, 2023 (“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

Executive Summary

Mallinckrodt performed a Reasonable Country of Origin Inquiry (“RCOI”) on suppliers believed to provide Mallinckrodt with materials or components containing 3TGs necessary to the manufacture of Mallinckrodt’s medical device products. Mallinckrodt’s suppliers listed 352 valid smelters and refineries (“smelters”) as possible sources for 3TGs in their components. Of the 352 listed smelters, Mallinckrodt identified 53 that may be sourcing from the Covered Countries. Mallinckrodt’s due diligence review indicated that 38 of these smelters have been audited and are conformant to the Responsible Minerals Assurance Process (“RMAP”). The remaining 15 smelters were subject to Mallinckrodt’s risk mitigation process consistent with 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 consistent with 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; and
Policy communicated directly to suppliers as part of the contracting process and as part of the Reasonable Country of Origin Inquiry (“RCOI”) process.
Implemented a Supplier Code of Conduct
Code available at;
Code included in agreements with suppliers.
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 Conflict Minerals Report (“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 352 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 3TG supply chain (OECD Step 2B);
Assess whether the smelters have carried out all elements of due diligence for responsible supply chains of minerals from the Covered Countries (OECD Step 2C); and
Where necessary, carry out, including through participation in industry-driven programs, joint spot checks at the relevant 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 seeks 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:
Global Witness
Le Congo N’est Pas a Vendre
The Business and Human Rights Resource Centre
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 they 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 352 smelters. Mallinckrodt identified 53 smelters that source, or there is reason to believe they may source, from the Covered Countries.

Mallinckrodt determined that 38 of these 53 smelters have been audited and are conformant to the RMAP, as of April 30, 2024.

Risk Mitigation

Mallinckrodt is committed to conducting risk mitigation on the 15 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 consistent with the principles of 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;
Seeking direct contact with relevant suppliers to determine, by specific part:
Whether 3TGs from specific smelter(s) were actually in Mallinckrodt’s supply chain during the Reporting Period;
Requested that supplier cease or minimize sourcing from identified high-risk smelters;
Requested that supplier contact identified high-risk smelters and encourage them to source from downstream suppliers with business practices in accordance with our supplier code of conduct and the OECD Due Diligence Guidance, and
Seeking direct engagement with each high-risk smelter to verify risk and to encourage the smelter to become conflict-free.

In 2023, the number of high-risk smelters listed in Mallinckrodt’s supply chain experienced a slight increase. This increase does not reflect a change in Mallinckrodt’s sourcing practices, rather the list of smelters reported by Mallinckrodt had remained largely the same year-over-year. The increase can be attributed to fewer smelters choosing to participate in the RMAP program, causing previously conformant facilities to now be designated as high-risk.

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 aim to take the following steps:

a.Continue to incorporate a Conflict Minerals clause into new and renewing supplier contracts;
b.Continue to directly contact suppliers and request suppliers obtain current, accurate, and complete information about the smelters in their respective supply chains;
c.Continue to directly contact suppliers and request that they, whenever possible, only source from conformant smelters when sourcing from the Covered Countries.
d.Request smelters sourcing from the Covered Countries to be audited and certified to a protocol recognized by the RMAP.
