Item 1.01

Entry Into a Material Definitive Agreement

On May 4, 2023, Lantheus Medical Imaging, Inc. (the "Company"), a wholly owned subsidiary of Lantheus Holdings, Inc. (the "Registrant"), entered into a First Amendment To Lease (the "Lease Amendment") with 201 Burlington Road Owner, LLC (the "Landlord"), which amends the Company's existing Office Lease with the Landlord dated February 14, 2022 (the "Existing Lease" and, together with the Lease Amendment, the "Lease"), to (i) add an additional premises in the north building of its leased Bedford, Massachusetts premises consisting of 41,655 rentable square feet for use as office and laboratory space (the "Additional Premises") for a term of 15 years and 4 months (the "Lease Amendment Rental Term") and (ii) extend the term of the Existing Lease for the Company's existing premises in Bedford, Massachusetts, consisting of 46,526 rentable square feet of office space (the "Existing Premises"), to be coterminous with the term of the lease of the Additional Premises. The Lease Amendment Rental Term will commence 11 months after the completion of the Landlord's work with respect to the Additional Premises, as described below.

The aggregate rent for both the Existing Premises and Additional Premises is approximately $83.4 million over the term of the Lease plus the Company's pro-ratashare of operating expenses, taxes and certain other costs, including utilities. The Company's obligations under the Lease are guaranteed by Registrant pursuant to a Guaranty dated February 14, 2022.

The Landlord, at its expense, will make certain improvements to the Additional Premises by September 1, 2023, subject to force majeure events and/or tenant delay (each as defined in the Lease). The Company will also undertake certain improvements to the Existing Premises and Additional Premises in accordance with customary terms in the Lease. The Landlord has agreed to reimburse the Company for up to $11.4 million in the aggregate for tenant improvements to the Additional Premises and Existing Premises, with the remainder to be paid by the Company, subject to customary terms and conditions contained in the Lease.

The Lease provides the Company with two options to extend the Lease for an additional five years. The Lease also provides the Company with the right to terminate if certain contingencies are not met within 12 weeks of the effective date of the Lease Amendment.

The Registrant plans to file the Lease as an exhibit to its Quarterly Report on Form 10-Qfor the quarter ending June 30, 2023, with confidential portions redacted. The foregoing description is qualified in its entirety by reference to the complete text of the Lease when filed.
