(“Life Molecular”), a subsidiary of Life Healthcare Group Holdings Ltd (“Life Healthcare”). As part of the acquisition, Ludger Dinkelborg, PhD, formerly CEO and Managing Director of Life Molecular Imaging, has been appointed Head of Research and Development at Lantheus effective August 1, 2025.

“We are thrilled to welcome Dr. Dinkelborg and the entire Life Molecular team to Lantheus,” said Brian Markison, CEO of Lantheus. “Ludger’s proven leadership, scientific expertise, and track record of advancing innovative radiopharmaceuticals will be instrumental as we expand and advance our innovative pipeline and pursue bold new opportunities to improve patient care.”

The transaction also provides Lantheus a robust Alzheimer’s disease radiodiagnostic commercial infrastructure, advanced R&D capabilities, and an established international footprint.

RMB, a division of FirstRand Bank Limited, acted as financial advisor to Life Healthcare, with A&O Shearman LLP and Cliffe Dekker Hofmeyr Inc. as legal advisors.

About Neuraceq^® (florbetaben F 18 injection)

Indication (approved by FDA on 23 June 2025)

Neuraceq^® is indicated for positron emission tomography (PET) of the brain to estimate amyloid beta neuritic plaque density in adults with cognitive impairment for:

•

Evaluation of Alzheimer’s disease (AD) and other causes of cognitive decline

•

Selection of patients who are indicated for amyloid beta-directed therapy as described in the prescribing information of the therapeutic products

Important Safety Information

Risk for Image Interpretation and Other Errors

Errors may occur in the estimation of brain amyloid beta neuritic plaque density during Neuraceq^® image interpretation. The use of clinical information in the interpretation of Neuraceq^® images has not been evaluated and may lead to an inaccurate assessment. Severe brain atrophy as well as motion artifacts that result in image distortion may limit the ability to distinguish gray and white matter on a Neuraceq^® scan.

Perform image interpretation independently of the patient’s clinical information. For cases where there is uncertainty as to the location of cortical signal, use co-registered anatomical imaging to improve localization of signal.

Radiation Risk

Neuraceq^® contributes to a patient’s overall long-term cumulative radiation exposure. Long-term cumulative radiation exposure is associated with an increased risk of cancer. Ensure safe drug handling to protect patients and health care providers from unintentional radiation exposure. Advise patients to hydrate before and after administration and to void frequently after administration.

Common Adverse Reactions

The overall safety profile of Neuraceq^® is based on data from 1,090 administrations of Neuraceq^® to 872 subjects. No serious adverse reactions related to Neuraceq^® administration have been reported. The most frequently observed adverse drug reactions in subjects receiving Neuraceq^® were injection site reactions consisting of pain (3.4%), erythema (1.7%), and irritation (1.1%).
