The initial term of the License Agreement is 15 years. The term of the License Agreement will automatically renew for additional 15 year terms, subject to Licensee Commercializing (as defined in the License Agreement) the Product in at least one country in the Territory prior to expiration of the initial term.

The foregoing description of the License Agreement does not purport to be complete and is subject to, and qualified in its entirety by reference to, the complete text of the License Agreement, which is filed as Exhibit 10.1 and is incorporated by reference herein.

Item 2.05. Costs Associated with Exit or Disposal Activities.

On June 24, 2025, as described in the Press Release, the Company announced a global restructuring, with the vast majority of estimated cost savings from reduced commercialization expense from the Company’s Europe operations. The Company expects these actions will reduce operating costs by approximately $70 million annually and is anticipated to be substantially completed by June 30, 2026.

Amarin anticipates that it will incur between approximately $30 million and $37 million in charges related to the restructuring, substantially all of which are cash expenditures for one-time termination benefits and associated costs. Amarin expects to record the charges in the second quarter of 2025 and to make substantially all of the related payments by December 31, 2025.

The estimated charges that the Company expects to incur, and the timing thereof, are subject to a number of assumptions, and actual results may differ materially from these estimates. The Company may also incur additional costs not currently contemplated due to events that may occur as a result of, or that are associated with, the foregoing.

Item 7.01. Regulation FD.

On June 24, 2025, the Company issued a press release announcing the License Agreement. A copy of this press release is furnished as Exhibit 99.1 to this Current Report on Form 8-K.
