Risks

• PYLARIFY's growth is dependent on the ability of PET manufacturing facilities (PMFs) to meet product demand, and FDA approval of new PMFs may be delayed or withdrawn.
• Maintaining adequate coding, coverage, and payment for PYLARIFY is critical, especially after the expiry of TPT Status, which could provide a financial incentive for hospitals to use competitive products.
• Potential for future generic entrants to the PYLARIFY market due to the expiry of its new chemical entity exclusivity period in 2026 could increase competition and impact market share.
• Neuraceq's growth is dependent on PMF capacity, coding/coverage/payment (lower MUC payment compared to competitors), and the ability to clinically and commercially differentiate it from other products.
• There is no assurance that the new formulation of the F-18 PSMA PET imaging agent will be approved by the FDA, or that the company will obtain TPT Status for it.
• Just-in-time manufacturing of radiopharmaceutical products relies on equipment reliability, timely raw material receipt, and timely shipment, making the business vulnerable to supply or distribution network disruptions.
• The company faces significant competition from larger, more diversified global companies in the markets for PYLARIFY, DEFINITY, and Neuraceq, which could lead to price reductions or loss of market share.
• Reforms to the U.S. healthcare system, including changes from the One Big Beautiful Bill Act (OBBBA) and potential Medicare cuts, may adversely affect the business by reducing patient coverage or reimbursement rates.
• Changes in management, including the retirement of the CEO and departure of the President, could disrupt business, hinder strategic planning, and negatively impact operations and relationships.
• Prevailing economic conditions, such as inflation and financial instability of customers, could adversely affect the business by reducing demand for healthcare services or delaying payments.
• Interruptions in the company's ability to fulfill obligations as a CDMO service provider or supplier of investigational products could adversely affect its reputation and business.
• Risks associated with recent acquisitions (Life Molecular, Evergreen) and dispositions (SPECT business) include integration challenges, unforeseen expenses/liabilities, and failure to realize anticipated benefits.
• The use of artificial intelligence (AI) or other emerging technologies could adversely impact the business if AI-generated content is deficient or if competitors adopt AI more quickly/effectively.
• There is no assurance that LNTH-2501 will be approved by the FDA or successfully commercialized.
• Reliance on partners for the development of certain product candidates exposes the company to risks if collaborators breach agreements or fail to perform successfully.
• Repurchases of common stock may affect the value of the common stock and could be viewed unfavorably by stockholders who prefer capital allocation elsewhere.
• Ongoing legal proceedings, including patent infringement lawsuits and a securities class action, create uncertainty and potential for significant fines or penalties.

Future Outlook

The company anticipates continued market expansion and penetration for PYLARIFY, DEFINITY, and Neuraceq. It expects to obtain FDA approval for its new F-18 PSMA PET imaging agent formulation and apply for TPT Status. The company plans to further develop and commercialize MK-6240 and NAV-4694, with PDUFA dates set for LNTH-2501 (March 29, 2026) and MK-6240 (August 13, 2026), and an NDA target action date for the new PSMA formulation (March 6, 2026). An NDA submission for NAV-4694 is expected in 2026, and a Phase 1b/2 study for RM2 in prostate cancer patients is planned for 2026. The company believes its current cash and cash equivalents, along with operating cash flow and access to its revolving credit facility, will be sufficient to meet cash requirements for the next twelve months and beyond.

Management Comments

• We continue to execute on our strategy to evolve into a fully integrated radiopharmaceutical company, supported by our increasingly diversified portfolio and our targeted initiatives to expand our pipeline, commercial, development and manufacturing capabilities.
• Over the past year, we announced multiple strategic transactions, which furthered our goal to focus on new markets and expand and diversify our capabilities and development pipeline with complementary assets.
• Our plan to successfully grow our PSMA PET franchise includes obtaining approval for and commercializing a new formulation of our F-18 PSMA PET imaging agent, conveying our products commercial and clinical value, negotiating and realizing the benefits from strategic contracts with customers in the U.S., expanding PSMA PET in appropriate new patient populations, and through strategic partnerships and collaborations, including outside of the U.S.
• We believe we will be able to increase use of DEFINITY through continued education of physicians and HCPs about the benefits of ultrasound enhancing agents in suboptimal echocardiograms.
• We believe future growth in Neuraceq revenue will depend on: (i) increased adoption and utilization of beta-amyloid PET and anti-amyloid therapeutics; (ii) increased educational efforts to drive awareness and adoption; (iii) increased utilization based on the updated Neuraceq package insert providing for use in patient selection for anti-amyloid therapies; and (iv) our ability to quantify amyloid beta neuritic plaque levels.

Industry Context

Lantheus is actively transforming into a fully integrated radiopharmaceutical company, aligning with a broader industry trend towards precision medicine and targeted therapies, particularly in oncology and neurology. The acquisitions of Life Molecular Imaging and Evergreen Theragnostics, along with the divestiture of the SPECT business, demonstrate a strategic pivot to high-growth radiopharmaceutical diagnostics and therapeutics. The competitive landscape for PSMA PET imaging agents is intensifying, with multiple players like Telix Pharmaceuticals, Novartis, and Blue Earth. The company's focus on developing new F-18 based agents and expanding its CDMO capabilities positions it to capitalize on the growing demand for these specialized products, despite the challenges posed by reimbursement changes and competition.

Comparison to Industry Standards

• PYLARIFY faces competition from three Gallium-68-based PSMA imaging agents (two from Telix Pharmaceuticals Limited and one from Novartis AG) and an F-18 PSMA PET imaging agent from Blue Earth Diagnostics Ltd. (a Bracco subsidiary). The loss of TPT Status for PYLARIFY, while competitors maintain it, creates a financial disadvantage in the hospital outpatient setting, as their products are reimbursed at ASP plus six percent compared to PYLARIFY's MUC-based payment.
• DEFINITY competes with other echocardiography ultrasound enhancing agents from GE HealthCare and Bracco, with Lantheus estimating it holds at least an 80% share of the U.S. segment for these agents.
• Neuraceq competes with two F-18 beta-amyloid-targeting PET imaging agents from Eli Lilly and Co (Lilly) and GE HealthCare. Neuraceq's MUC-based payment rate is lower than that of some competitive imaging agents, potentially impacting clinical decision-making.
• For PNT2003, principal competitors may include Novartis AG, ITM Radiopharma, Curium Pharma, and RayzeBio (acquired by Bristol Myers Squibb).
• For MK-6240 and NAV-4694, principal competitors may include Lilly and GE HealthCare.

Legal Proceedings

• Advanced Accelerator Applications USA, Inc. and Advanced Accelerator Applications SA (Novartis entities) sued the company for patent infringement in the U.S. District Court for the District of Delaware on January 26, 2024, in response to the company's Abbreviated New Drug Application and Paragraph IV certification for PNT2003.
• The company filed a patent infringement lawsuit against a healthcare-related imaging software developer on February 23, 2024; the court dismissed the developer's motion to dismiss as to invalidity and granted it as to certain allegations of infringement.
• A putative securities class action, Margolis v. Lantheus Holdings, Inc., et al., was initiated on September 9, 2025, in the U.S. District Court for the Southern District of New York, alleging materially false or misleading statements or omissions in violation of the Exchange Act.
• A shareholder derivative action, Jones v. Markison et al., was filed on October 31, 2025, in the same court, repeating allegations from the securities class action and asserting claims for alleged breaches of fiduciary duties, gross mismanagement, corporate waste, unjust enrichment, and violation of Section 14(a) of the Exchange Act.

Stakeholder Impact

• Shareholders: Experience significant decline in net income and EPS, but benefit from a new, larger share repurchase program. The strategic acquisitions and pipeline advancements could offer long-term value, but management changes introduce uncertainty.

Key Dates

Recommendation

The company's Q3 2025 financial results show a substantial decline in net income and EPS, primarily due to increased operating expenses from recent acquisitions and R&D investments, and a decrease in PYLARIFY's net sales price. This short-term financial underperformance, coupled with leadership transitions and ongoing legal challenges, presents immediate headwinds. However, the company is undergoing a significant strategic transformation, divesting non-core assets and making substantial investments in high-growth radiopharmaceutical diagnostics and therapeutics through acquisitions (Life Molecular, Evergreen) and pipeline advancements (LNTH-2501, MK-6240, new PSMA formulation). These strategic moves, while impacting current profitability and cash flow, are aimed at positioning the company for long-term growth in attractive markets. For a seasoned investor, a 'Hold' recommendation is appropriate, acknowledging the current financial pressures and uncertainties but recognizing the potential for future value creation from the strategic repositioning and pipeline development.
