Other Events.

On October 21, 2025, Jazz Pharmaceuticals, Inc. and Jazz Pharmaceuticals Ireland Ltd., subsidiaries of Jazz Pharmaceuticals plc (collectively, the “Company”) entered into a global settlement agreement (the “Settlement Agreement”) with Avadel CNS Pharmaceuticals LLC and Flamel Ireland Limited, subsidiaries of Avadel Pharmaceuticals plc (collectively, “Avadel”) to settle all claims relating to all disputes between the parties, including the Company’s previously disclosed ongoing patent infringement litigation against Avadel in the U.S. District Court for the District of Delaware (the “Court”) and Avadel’s counterclaims alleging anticompetitive conduct by the Company and other alleged conduct related to Avadel trade secrets and contracts between the parties, as well as Avadel’s ongoing patent infringement litigation in the Court against the Company. Pursuant to the Settlement Agreement, the Company has agreed to (a) grant a license to Avadel, effective immediately to any past, present, or future patents that could be asserted by the Company against Avadel’s Lumryz product for use in indications currently approved by the U.S. Food and Drug Administration (the “FDA” and such indications, the “Narcolepsy Indications”), and (b) grant a license to Avadel effective March 1, 2028 to any past, present, or future patents that could be asserted by the Company against Avadel’s Lumryz products for any other indications or uses not currently approved by the FDA (the “Non-Narcolepsy Indications”), including all present and future indications, strengths, conditions of use, dosages, doses, dosage forms, and presentations. Pursuant to the Settlement Agreement, Avadel has agreed to pay royalties to the Company of 3.85% (subject to a potential reduction to 3.75%) on net sales of its Lumryz product for Narcolepsy Indications commencing October 1, 2025, and beginning March 1, 2028, to pay royalties to the Company of 10% (subject to a potential reduction to 9.5%) on net sales of its Lumryz product for Non-Narcolepsy Indications. Avadel has also agreed not to market, offer for sale, take orders for, distribute, promote, or provide patient support services with respect to Avadel Licensed Products for Non-Narcolepsy Indications before March 1, 2028, and shall pay royalties to the Company of 80% of such unpermitted net sales of its Lumryz product for Non-Narcolepsy Indications from October 1, 2025 through February 29, 2028. Pursuant to the Settlement Agreement, Avadel grants the Company a covenant not to sue for infringement of any past, present or future patents that could be asserted against the Company’s Xywav or Xyrem products, including all present and future indications, strengths, conditions of use, dosages, doses, dosage forms, and presentations. The Company has not agreed to waive or otherwise consent to the “breaking” of the Orphan Drug Exclusivity for Xywav in idiopathic hypersomnia as part of this settlement. Pursuant to the Settlement Agreement, the Company has agreed to (a) pay a total of $90 million in a lump sum in settlement of Avadel’s pending claims against the Company and (b) waive its right to receive certain royalties the Court previously ordered Avadel to pay the Company on sales of Avadel’s Lumryz product through September 30, 2025. The Company plans to use cash on hand to fund the Settlement Agreement’s obligation. The Company expects to record a pre-tax charge of approximately $90 million associated with the Settlement Agreement in the third quarter of 2025.

The Settlement Agreement obligates the parties to promptly file stipulations of dismissal with the Court to dismiss or otherwise abandon the pending legal proceedings. The Settlement Agreement, in which the Company denies all alleged wrongdoing, also includes releases by each of the Company, on the one hand, and Avadel, on the other hand, and each of their past, present and future affiliates, directors, officers, employees and other related parties, for all conduct concerning any of the matters alleged, or that could have been alleged, in the lawsuit.
