WHAT IS THIS ABOUT?

Mallinckrodt is a manufacturer of opioid pain medication that filed for chapter 11 bankruptcy in October 2020. On June 17,2021,Mallinckrodt plc and its affiliates (the "Debtors") filed their Plan of Reorganization (the "Plan") in the United States Bankruptcy Court for the District of Delaware and their related Disclosure Statement. You may have the right to vote on the Plan of Reorganization.

WHO CAN VOTE ON THE PLAN?

Specific details about voting are set forth below in this notice and at MNKvote.com.

WHAT DOES THE PLAN PROVIDE?

Mallinckrodt's Plan channels claims based on harm or injury related to the Debtors' manufacturing of opioids and related activities to one or more opioid trusts. These opioid trusts will be established for the purpose of distributing money to individuals and corporate entities holding Opioid Claims and for abatement of the opioid crisis. If the Plan is approved by the Bankruptcy Court and you have an Opioid Claim,you will be entitled to assert your claim directly against the applicable opioid trust at a later time. There is nothing you need to do right now to assert your Opioid Claim. You will be notified of how to assert your Opioid Claim against an opioid trust at a later date. The Plan,if approved,will forever prohibit any opioid claimants from asserting any Opioid Claim or seeking any money on account of any Opioid Claim against the Debtors,their officers and directors,or certain other parties specified in the Plan as the "Protected Parties." The Official Committee of Opioid Related Claimants is a Bankruptcy Court-appointed representative of Opioid Claimants in the Debtors' bankruptcy cases and has set forth its position letter regarding the Plan,which can be obtained free of charge at MNKVote. com.
