Explanation of Responses:

1. On October 12, 2020, Mallinckrodt plc, an Irish public limited company in examination under Part 10 of the Companies Act 2014 of Ireland ("Mallinckrodt"), and certain of its subsidiaries voluntarily initiated proceedings under chapter 11 of title 11 of the United States Code (the "Bankruptcy Code") in the U.S. Bankruptcy Court for the District of Delaware (the "Bankruptcy Court"). On February 3, 2022, the Bankruptcy Court issued an opinion (which was subsequently revised on February 8, 2022 to make minor corrections) stating its intention to confirm Mallinckrodt's Fourth Amended Joint Plan of Reorganization of Mallinckrodt Plc and Its Debtor Affiliates Under Chapter 11 of the Bankruptcy Code.

2. (Continued from Footnote 1) On March 2, 2022, the Bankruptcy Court entered an order confirming the Fourth Amended Joint Plan of Reorganization (with Technical Modifications) of Mallinckrodt Plc and Its Debtor Affiliates Under Chapter 11 of the Bankruptcy Code (as amended, supplemented or otherwise modified, the "Plan"), and on June 16, 2022 (the "Effective Date"), the Plan became effective and Mallinckrodt emerged from bankruptcy.

3. On the Effective Date, all of Mallinckrodt's previously outstanding ordinary shares (the "Ordinary Shares"), including options, warrants, rights, restricted stock units or other securities or agreements to acquire such ordinary shares, were cancelled and extinguished pursuant to the Plan.
