On December 26, 2022, Amarin Corporation plc (the "Company") entered into a Settlement Agreement (the "Settlement Agreement") with Health Net, LLC that resolves previously disclosed patent infringement litigation in the U.S. District Court in Delaware. The specific terms of the settlement are confidential. The Company is pleased with the outcome and believes entering into the Settlement Agreement will provide significant value in the market with payors.

The Company will continue to vigorously defend its intellectual property rights related to VASCEPA.
