INVESTIGATION REMINDER: The Schall Law Firm Announces it is Investigating Claims Against Mallinckrodt plc and Encourages Investors with Losses to Contact the Firm

The Schall Law Firm, a national shareholder rights litigation firm, announces that it is investigating claims on behalf of investors of Mallinckrodt plc (“Mallinckrodt” or “the Company”) (NYSE American: MNK) for violations of the securities laws.

The investigation focuses on whether the Company issued false and/or misleading statements and/or failed to disclose information pertinent to investors. Mallinckrodt is the subject of two open letters released by The Buxton Helmsley Group, Inc. (“BHG”) on March 17, 2023. A letter addressed to Senators Elizabeth Warren and Sheldon Whitehouse claims that BHG is “delivering the results of an extensive investigation into financial misconduct at the Company involving an evidenced scheme of concealing asset value depreciation/impairment expenses, in violation of GAAP ASC 350, 360 and Regulation S-X, taking place both before and after the Company’s Chapter 11 Reorganization.” In the second letter, addressed to the Company’s management, BHG notes that, “This Company has already, with the same Chief Financial Officer running the books pre- and post-reorganization, laid out the Company’s standard for determining the fair value of assets securing capital structure interests, and is apparently continuing such misconduct through failure (post-reorganization) to record billions of dollars in asset value depreciation/impairment expenses, which are evidenced by simply applying their prior-professed internal standard for determining the fair value of assets securing the Company’s capital structure, and – therefore – asset value impairment.”
