As Jazz Pharmaceuticals plc (the "Company") has previously disclosed, a number of complaints, including, from June 2020 to September 2020, several complaints styled as class actions and, from March 2021 to May 2022, several additional complaints, were filed on behalf of purported direct and indirect Xyrem purchasers, alleging that the Company's actions leading up to, and entering into, patent litigation settlement agreements with generic drug manufacturers who had filed abbreviated new drug applications ("ANDAs" and such filers, "ANDA filers"), violate U.S. state and federal antitrust, consumer protection and unfair competition laws. This group of cases was consolidated for multidistrict litigation ("MDL") proceedings before the U.S. District Court for the Northern District of California (the "Court") in December 2020.

On April 7, 2025, Jazz Pharmaceuticals Ireland Limited, a wholly-owned subsidiary of the Company, entered into a preliminary class settlement agreement (the "preliminary class settlement agreement") with the class of indirect Xyrem purchasers to settle all claims of participating class members against the Company with respect to the Company's actions leading up to, and entering into, patent litigation settlement agreements with the ANDA filers.

Pursuant to the preliminary class settlement agreement, which was entered into with counsel representing the class representatives, the Company has agreed to pay a total of $145 million in a lump sum. The Company plans to use cash on hand to fund the preliminary class settlement agreement's obligations. The Company expects to record a pre-tax charge of approximately $145 million associated with this preliminary class settlement agreement in the first quarter of 2025.
