Given Company's Evolution Milestones

Given Company's Transformative Moments

The company's trajectory has been defined by a pivot from general diagnostic imaging agents to high-value, targeted radiopharmaceuticals, especially in oncology. This shift is defintely a key takeaway for investors.

The 2021 FDA approval and subsequent commercial success of PYLARIFY (piflufolastat F 18) for prostate cancer imaging was the single most transformative event in recent history. It became the number one ordered PSMA PET imaging agent in the U.S., with over 500,000 scans performed by August 2025. This product alone drove the company's revenue to new heights, with PYLARIFY sales hitting $257.7 million in the first quarter of 2025.

The strategic focus on becoming a fully integrated radiopharmaceutical-focused company is clear from the 2025 moves:

• The acquisitions of Evergreen Theragnostics and Life Molecular Imaging, which added new growth drivers like the Alzheimer's diagnostic Neuraceq® and the neuroendocrine tumor agent OCTEVY™.
• The planned divestiture of the lower-growth SPECT business, streamlining the portfolio to focus on high-growth PET and theranostics.
• The updated full-year 2025 revenue guidance, projecting between $1.550 billion and $1.585 billion, shows the immediate financial impact of this focused strategy.

This aggressive repositioning, which you can read more about in Breaking Down Lantheus Holdings, Inc. (LNTH) Financial Health: Key Insights for Investors, is about building a sustainable pipeline beyond PYLARIFY, especially with the planned third-quarter 2025 NDA filing for the next-generation tau imaging agent, MK-6240. The message is simple: they are shedding the old to double down on the future of precision medicine.

Here's the quick math on their current scale: the company is forecasting adjusted earnings per share (EPS) for the full year 2025 to be in the range of $6.60 to $6.70, reflecting a high-margin business model.

Lantheus Holdings, Inc. (LNTH) Ownership Structure

Lantheus Holdings, Inc. is overwhelmingly controlled by institutional money, a common trait for high-growth biotech and radiopharmaceutical companies. As of November 2025, institutional investors hold an extremely high percentage of the shares, giving them significant influence over strategic decisions and board appointments.

Given Company's Current Status

Lantheus Holdings, Inc. is a publicly traded company, listed on the NASDAQ Global Market under the ticker symbol LNTH. This status means its ownership is dispersed among millions of shareholders, but the vast majority of voting power rests with large financial institutions.

Its market capitalization, a key measure of its public size, stood at approximately $3.55 billion as of November 2025, positioning it firmly in the mid-cap space. For the full fiscal year 2025, the company provided updated revenue guidance in the range of $1.475 billion to $1.51 billion, underscoring its scale and commercial success in the radiopharmaceutical market. This is a very institutional-heavy stock. Mission Statement, Vision, & Core Values of Lantheus Holdings, Inc. (LNTH).

Given Company's Ownership Breakdown

The company's ownership structure is characterized by an extremely high concentration of institutional holdings, which often exceeds the total number of shares outstanding (a common market anomaly due to short selling and complex financial instruments). Honestly, this level of institutional control-reported to be as high as 99.06%-means individual investors have minimal collective voting power. Here's the quick math for the general breakdown:

What this estimate hides is the true level of institutional dominance; the reported 99.06% figure suggests that institutional investors effectively control the entire company's float, plus some. This means the stock's price movements are defintely driven by large fund flows, not by retail sentiment.

Given Company's Leadership

Lantheus is currently navigating a significant leadership transition, which is a near-term risk to monitor for strategic continuity. The Board is actively searching for a new Chief Executive Officer following the planned retirement of the current CEO.

The key leaders steering the company as of November 2025 include:

• Mary Anne Heino: Executive Chairperson and Interim Chief Executive Officer. She stepped into the Executive Chairperson role in November 2025 and will assume the Interim CEO role on January 1, 2026, bringing her prior CEO experience from 2015 to 2024 back to the forefront during the search.
• Brian Markison: Chief Executive Officer (until December 31, 2025). He will transition to a strategic advisor role through March 2026 to ensure a smooth handover.
• Amanda Morgan: Chief Commercial Officer. She is crucial for the commercial execution of key products like PYLARIFY.
• Ludger Dinkelborg, PhD: Head of Research and Development. His role is vital for advancing the robust radiodiagnostic and radiotherapeutic pipeline, especially post-acquisition of Life Molecular Imaging in July 2025.

This interim structure is a temporary measure, but the appointment of a seasoned former CEO like Ms. Heino as the interim leader provides a steady hand during a period of executive change and the departure of President Paul Blanchfield.

• Distribution Network: Utilizing a decentralized network that ensures rapid delivery to nuclear medicine departments and imaging centers, minimizing decay loss and maximizing patient access.
• Pipeline Advancement: Investing heavily in R&D, with a focus on next-generation agents. They plan to submit an NDA for MK-6240, a tau imaging agent for Alzheimer's disease, in the third quarter of 2025.

The planned divestiture of their SPECT business by the end of 2025 is a clear move to simplify their operations and focus capital on the higher-growth PET and therapeutic radiopharmaceutical segments.

Lantheus Holdings, Inc.'s Strategic Advantages

The company maintains its market position through a combination of proprietary technology, supply chain control, and first-mover advantages in key diagnostic areas. This isn't a commodity business; it's highly specialized and difficult to replicate at scale.

• Market Leadership in PSMA PET: PYLARIFY is a blockbuster product, establishing Lantheus as the leader in prostate cancer imaging, a high-growth oncology segment.
• Proprietary Production/Supply Chain: The use of F-18 for PYLARIFY, with its relatively longer half-life compared to other isotopes, allows for a wider geographic reach and more resilient supply chain, which is a major competitive moat (a sustainable competitive advantage).
• Pipeline and Platform Diversification: Strategic acquisitions in 2025, such as Evergreen Theragnostics, immediately expand their capabilities into the emerging radioligand therapy (RLT) space, positioning them to both 'Find' and 'Fight' cancer.
• High Barriers to Entry: The regulatory complexity, capital intensity of cyclotron infrastructure, and need for specialized logistics create significant hurdles for new competitors.

The expected 2026 launch of a new PYLARIFY formulation that could increase batch size by approximately 50% is a direct action to enhance production efficiency and supply resilience against competitive pressures.

Lantheus Holdings, Inc. (LNTH) How It Makes Money

Lantheus Holdings, Inc. makes money primarily by developing, manufacturing, and commercializing radiopharmaceuticals and medical imaging agents that help clinicians diagnose and manage diseases, particularly in oncology and cardiology. The core of their revenue comes from the sale of their two flagship products: PYLARIFY, a diagnostic agent for prostate cancer, and DEFINITY, an ultrasound enhancing agent for cardiac imaging.

You're looking at a company that's transitioning its revenue base from legacy products to a higher-growth, specialized radiopharmaceutical oncology franchise. This shift is clear in their Q3 2025 results, which showed worldwide revenue of $384.0 million, a 1.4% increase year-over-year.

Lantheus Holdings, Inc.'s Revenue Breakdown

The company's revenue is concentrated in two major products, PYLARIFY and DEFINITY, which together accounted for over 84% of total sales in the third quarter of 2025. This concentration means their financial health is highly sensitive to the market dynamics of these two agents.

Business Economics

The economics of Lantheus are defined by high-value, short-half-life radiopharmaceuticals (like PYLARIFY) and a mature, steady-cash-flow product (DEFINITY). The radiopharmaceutical market is a specialized niche with high barriers to entry due to complex manufacturing, logistics, and regulatory hurdles.

• PYLARIFY's Pricing Pressure: While U.S. volumes for PYLARIFY were up 3.3% in Q3 2025, the product's sales revenue still decreased by 7.4% year-over-year, clearly indicating price compression in the market. Management is working on pricing stabilization, but competition is intense.
• Supply Chain Moat: A key economic advantage is the complex, just-in-time supply chain required for radiopharmaceuticals, which have a short shelf life. Lantheus is mitigating future supply risk by developing a new F-18 PSMA PET formulation expected to launch in 2026, which could increase batch size by approximately 50%.
• Acquisition-Driven Diversification: Strategic acquisitions, like Life Molecular Imaging in July 2025, immediately broadened their portfolio with products like Neuraceq, which contributed $20.4 million in Q3 2025 revenue. This strategy aims to diversify beyond the prostate cancer franchise and into the high-potential Alzheimer's disease imaging market.
• High Gross Margin Potential: Despite a Q3 2025 gross profit margin decline to 53.5%, the radiopharmaceutical business model inherently allows for high margins once development and manufacturing scale, a key driver for long-term profitability.

The name of the game is securing the supply chain and expanding the clinical utility of their agents. You can find more detail on their long-term strategy in their Mission Statement, Vision, & Core Values of Lantheus Holdings, Inc. (LNTH).

Lantheus Holdings, Inc.'s Financial Performance

Lantheus's financial performance in 2025 reflects a company absorbing acquisition costs and navigating pricing pressure on its top product while still generating significant cash flow.

• Revenue Guidance: The updated full-year 2025 revenue guidance is between $1.49 billion and $1.51 billion, with the midpoint at $1.5 billion. This is a defintely solid outlook, but it's important to note the slight narrowing from earlier in the year.
• Profitability Metrics: Adjusted fully diluted earnings per share (EPS) for Q3 2025 was $1.27, a 25.3% decrease from the prior year, reflecting higher operating expenses from integrating recent acquisitions and increased R&D. Adjusted operating income for the quarter was $119.6 million.
• Cash Position and Capital Allocation: The company reported strong Q3 2025 free cash flow of $94.7 million, a crucial indicator of business health. As of September 30, 2025, cash and cash equivalents stood at $382.0 million, even after spending on acquisitions and a $100 million share repurchase in the quarter.
• Full-Year EPS Outlook: Management reiterated its full-year 2025 adjusted EPS guidance in the range of $5.50 to $5.65. This suggests they expect the profitability pressures to moderate in the fourth quarter.

The company is using its cash to buy back stock and acquire strategic assets, which is a confident move, but the drop in gross margin and adjusted EPS highlights the near-term cost of this aggressive expansion strategy.
