CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS
Some of the statements contained in this Annual Report on Form 10-K are forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). These forward-looking statements, including, in particular, statements about our plans, strategies, prospects and industry estimates, are subject to risks and uncertainties. These statements identify prospective information and can generally be identified by words such as “anticipates,” “believes,” “can,” “could,” “designed,” “estimates,” “expects,” “hopes,” “intends,” “launch,” “may,” “pipeline,” “plans,” “potential,” “predicts,” “seeks,” “should,” “target,” “will,” “would” and similar expressions, or by express or implied discussions regarding potential marketing approvals or new indications for the product candidates or approved products described in this Annual Report on Form 10-K, or regarding potential future revenues from such product candidates and products. Examples of forward-looking statements include statements we make relating to our outlook and expectations including, without limitation, in connection with:
Continued market expansion and penetration for our established commercial products, particularly PYLARIFY and DEFINITY, in a competitive environment in which other imaging agents have been approved and are being commercialized, and our ability to clinically and commercially differentiate our products;
Our ability to have third parties manufacture our products and our ability to manufacture DEFINITY in our in-house manufacturing facility;
The global availability of Molybdenum-99 (“Mo-99”) and other raw materials and key components;
Our strategies, future prospects, and projected growth, including revenue related to our collaboration agreements with POINT Biopharma Global Inc. (“POINT”), including our ability to obtain FDA approval for PNT2002 and PNT2003;
Our ability to satisfy our obligations under our existing clinical development partnerships using MK-6240 as a research tool and under the license agreement through which we have rights to MK-6240, and to further develop and commercialize it as an approved product;
Our ability to successfully execute on our agreements with Perspective Therapeutics, Inc. (“Perspective”), including finalizing the license agreements in the event we exercise our options to do so, and satisfying the closing conditions for the sale of the Somerset, NJ manufacturing facility and related assets, the value of our current and any future equity interest in Perspective, and Perspective’s ability to successfully develop its alpha-particle therapy and innovative platform technology;
The efforts and timing for clinical development, regulatory approval and successful commercialization of our product candidates and new clinical applications and territories for our products, in each case, that we or our strategic partners may undertake; and
Our ability to identify and acquire or in-license additional radiopharmaceutical therapeutic and diagnostic product opportunities in oncology and other strategic areas to grow our pipeline of products.
Forward-looking statements are based on our current expectations and assumptions regarding our business, the economy and other future conditions.

PART I
Item 1. Business
Overview
We are the leading radiopharmaceutical-focused company, delivering life-changing science to enable clinicians to Find, Fight and Follow disease to deliver better patient outcomes. We classify our products in three categories: Radiopharmaceutical Oncology, Precision Diagnostics, and Strategic Partnerships and Other Revenue. Our Radiopharmaceutical Oncology diagnostics and therapeutic candidates help healthcare professionals (“HCPs”) Find, Fight and Follow cancer, with a focus in prostate cancer. Our leading Precision Diagnostic products assist HCPs to Find and Follow diseases, with a focus in cardiology. Our Strategic Partnerships focus on enabling precision medicine through the use of biomarkers, digital solutions and pharma solutions platforms.
Our commercial products are used by cardiologists, internal medicine physicians, nuclear medicine physicians, oncologists, radiologists, sonographers, technologists, and urologists working in a variety of clinical settings. We believe that our diagnostic products provide improved diagnostic information that enables HCPs to better detect and characterize, or rule out, disease, with the potential to achieve better patient outcomes, reduce patient risk and limit overall costs throughout the healthcare system.
We produce and market our products throughout the United States (the “United States” or the “U.S.”), selling primarily to hospitals, independent diagnostic testing facilities, and radiopharmacies. We sell our products outside the U.S. through a combination of direct distribution in Canada and third party distribution relationships in Europe, Canada, Australia, Asia-Pacific, Central America and South America.
Our executive offices are located in Bedford, Massachusetts, with additional offices in North Billerica, Massachusetts; Somerset, New Jersey (subject to the satisfaction of closing conditions for the sale of the Somerset facility and related assets to Perspective anticipated in the first half of 2024); Montreal, Canada and Lund, Sweden.
CEO Succession Plan
On January 23, 2024, we announced that, effective March 1, 2024, Brian Markison, our current Chair of the Board of Directors (“Board”), will become our Chief Executive Officer, and Mary Anne Heino, our current Chief Executive Officer, will retire and become the Chair of the Board. As part of this leadership transition, Mr. Markison assumed the role of Executive Chair of the Board as of January 23, 2024 until the effectiveness of his Chief Executive Officer appointment in March, and Board Member Julie McHugh became Lead Independent Director.
Strategic Agreements with Perspective Therapeutics
On January 9, 2024, we announced that we entered into multiple strategic agreements with Perspective, a radiopharmaceutical company that is pursuing advanced treatment applications for cancers throughout the body. Under the agreements, we obtained an option to exclusively license Perspective’s Pb212-VMT- ⍺-NET, a clinical stage alpha therapy in development for the treatment of neuroendocrine tumors, and an option to co-develop certain early-stage therapeutic candidates targeting prostate cancer using Perspective’s innovative platform technology for an aggregate upfront payment of $28 million in cash. We also agreed to purchase up to 19.9% of Perspective’s outstanding shares of common stock for up to approximately $33 million, subject to Perspective’s completion of a qualified third-party financing transaction and certain other closing conditions. In addition, Perspective agreed to acquire the assets and associated lease of our radiopharmaceutical manufacturing facility in Somerset, New Jersey. Following satisfaction of the closing conditions, on January 22, 2024, our subsidiary, Lantheus Alpha purchased 56,342,355 shares of Perspective’s common stock at a purchase price of $0.37 per share in a private placement transaction. The total consideration for the purchase was approximately $20.8 million in cash, which resulted in Lantheus Alpha holding approximately 10.74% of Perspective’s common stock as of the purchase date and retaining the right to purchase additional shares to bring its ownership up to an aggregate of 19.9%.
Exclusive License for PNT2002 & PNT2003
On December 20, 2022, we announced the closing of a set of strategic collaborations with POINT, in which we were granted a license to exclusive worldwide rights (excluding Japan, South Korea, China (including Hong Kong, Macau and Taiwan), Singapore and Indonesia) to co-develop and commercialize POINT’s PNT2002 and PNT2003 product candidates. PNT2002 is a PSMA-targeted radiopharmaceutical therapy in development for the treatment of metastatic castration-resistant prostate cancer (“mCRPC”). PNT2003 is a somatostatin receptor (“SSTR”) therapy with non-carrier added lutetium-177, which is in registration to treat patients with SSTR-positive neuroendocrine tumors.
On December 27, 2023, Eli Lilly and Company announced the completion of its acquisition of POINT. The acquisition is not expected to impact the status of the license agreements related to these product candidates or the work being performed in connection with those license agreements and our collaboration with POINT.

PNT2002
With respect to PNT2002, POINT is generally responsible for funding and development activities required for FDA approval, including generating all clinical and nonclinical data, analysis and other information, and we are responsible for preparing for and seeking regulatory approval, as well as performing and funding all future development and commercialization following such approval. POINT will be responsible for all manufacturing of PNT2002, subject to certain exceptions described in the license and collaboration agreement between Lantheus Two and POINT, dated November 11, 2022 (the “PNT2002 License Agreement”).
In April 2023, we announced with POINT that the FDA had granted Fast Track designation for PNT2002. Fast Track is a process designed to facilitate the development and expedite the review of drugs to treat serious conditions and address unmet needs.
On December 18, 2023, we announced positive topline results from SPLASH. SPLASH is designed to evaluate the efficacy and safety of PNT2002 in patients with mCRPC who have progressed following treatment with an androgen receptor pathway inhibitor (“ARPI”). The SPLASH trial met its primary endpoint, demonstrating a median radiographic progression-free survival (rPFS) per blinded independent central review of 9.5 months for patients treated with PNT2002, compared to 6.0 months for patients treated with ARPI in the control arm, a statistically significant 29% reduction in the risk of radiographic progression or death (hazard ratio (“HR”) 0.71; p=0.0088). At the time of the analysis, interim overall survival (“OS”) results were immature (46% of protocol-specified target OS events reached), and the HR was 1.11. We expect more mature overall survival data in 2024 prior to the potential submission of a New Drug Application (“NDA”).
PNT2002 demonstrated a favorable safety profile with grade ≥3 treatment-emergent adverse events (“TEAEs”) per Common Terminology Criteria for Adverse Events, serious TEAEs, and TEAEs leading to discontinuation occurring at lower rates in the PNT2002 arm than in the ARPI arm (30.1%, 17.1%, and 1.9% versus 36.9%, 23.1%, and 6.2%, respectively).
The open-label study randomized 412 patients with PSMA-expressing mCRPC who had progressed on ARPI therapy and either refused or were not eligible for chemotherapy, in a 2:1 randomization ratio. At the time of the analysis, 84.6% of patients who experienced progressive disease in the control arm subsequently crossed over to receive PNT2002. SPLASH was conducted across the United States, Canada, Europe, and the United Kingdom. Eighty percent of SPLASH patients resided in North America and approximately ten percent of all participants were Black or African American.
During 2023, we worked on establishing an Expanded Access Program, (“EAP”), for PNT2002. EAPs, which are also referred to as compassionate use programs, provide a potential pathway for patients with serious or life-threatening conditions to gain access to an investigational drug for treatment outside of a clinical trial. We expect to enroll the first patient in the EAP for PNT2002 during the first quarter of 2024.
PNT2003
With respect to PNT2003, POINT is responsible for curating all data, analysis and other information necessary for regulatory approval, and supporting us in the preparation of regulatory filings. We are responsible for preparing for and seeking regulatory approval of all such applications, as well as performing and funding all future development and commercialization of PNT2003 following such approval. POINT will be responsible for all manufacturing of PNT2003, subject to certain exceptions described in the license and collaboration agreement between Lantheus Three and POINT, dated November 11, 2022 (the “PNT2003 License Agreement”).
On January 11, 2024, we announced that our ANDA for Lutetium Lu 177 Dotatate (177Lu-PNT2003) had been accepted for filing by the FDA. On January 26, 2024, we were sued in the District Court for the District of Delaware by Advanced Accelerator Applications USA, Inc. and Advanced Accelerator Applications SA, each a Novartis entity, for patent infringement in response to the Company’s ANDA filing. Based on the most recent update to the FDA’s online paragraph IV database listings, we believe we are the first applicant to have filed a substantially complete ANDA for Lutetium Lu 177 Dotatate containing a Paragraph IV certification under the provisions of the Hatch-Waxman Act. As the first applicant, we believe we will be eligible for 180 days of generic marketing exclusivity in the U.S.
Under the Hatch-Waxman Act, any company submitting an ANDA must make certain certifications with respect to the patent status of the drug for which it is seeking approval. In the event that such applicant plans to challenge the validity or enforceability of an existing listed patent or asserts that the proposed product does not infringe an existing listed patent, it files a “Paragraph IV” certification. We filed a Paragraph IV certification in connection with PNT2003. In the case of ANDAs, the Hatch-Waxman Act provides for a potential 180-day period of generic exclusivity for the first company to submit an ANDA with a Paragraph IV certification. This filing triggers a regulatory process in which the FDA is required to delay the final approval of subsequently filed ANDAs containing Paragraph IV certifications until 180 days after the first commercial marketing. When litigation is brought by the
5

Table of Contents

patent holder in response to a Paragraph IV certification (like the Novartis entities did for our ANDA for PNT2003), the FDA generally may not approve the ANDA until the earlier of 30 months or a court decision finding the patent invalid, not infringed or unenforceable. The submission of our ANDA for PNT2003 could result in protracted and expensive patent litigation and the outcome of such litigation is uncertain.
Acquisition of Cerveau
On February 6, 2023, we announced that we acquired Cerveau. Cerveau holds the rights under a license agreement to develop and commercialize MK-6240, an investigational second-generation F 18-labeled PET imaging agent that targets Tau tangles in Alzheimer’s disease. Under the terms of our purchase agreement, we paid the stockholders of Cerveau (the “Selling Stockholders”) an upfront payment of $35.0 million in February 2023 and an additional $10.0 million in May 2023 upon the successful completion of a technology transfer. The Selling Stockholders are also eligible to receive additional development and commercial milestone payments. Additionally, we will pay double-digit royalty payments for research revenue and commercial sales. Research revenue is derived from existing partnerships with pharmaceutical companies that use MK-6240 in clinical trials and includes milestone and dose-related payments. Pursuant to the terms of the stock purchase agreement for Cerveau, certain members of the Selling Stockholders will also provide transition and clinical development services for a prescribed time following the closing of the transaction.
Our Portfolio of Commercial Products
Radiopharmaceutical Oncology
Our commercial product in our Radiopharmaceutical Oncology category includes the following:
PYLARIFY (also known as piflufolastat F 18, 18F-DCFPyL or PyL) is an F 18-labelled PSMA-targeted PET imaging agent used with PET/computed tomography (“CT”). PYLARIFY is indicated in the U.S. for PET imaging of PSMA-positive lesions in men with prostate cancer with suspected metastasis who are candidates for initial definitive therapy and in men with suspected recurrence based on elevated serum prostate-specific antigen (“PSA”) levels. Piflufolastat F 18 is approved under the name PYLCLARI in Europe and licensed by us to Curium.
Precision Diagnostics
Our commercial products in our Precision Diagnostics category include the following:
DEFINITY is an injectable ultrasound enhancing agent with perflutren-containing lipid microspheres, or microbubbles, that is used in echocardiography exams. We offer two formulations of DEFINITY, one of which requires refrigerated storage (branded DEFINITY) and one which allows both storage and shipment at room temperature and provides clinicians an additional choice for greater utility of this formulation in broader clinical settings (branded DEFINITY RT). The indication for both formulations in the U.S. is for use in patients with suboptimal echocardiograms to opacify the left ventricular chamber and to improve the delineation of the left ventricular endocardial border. We believe we are currently the leading worldwide provider of ultrasound enhancing agents for use in echocardiography.
TechneLite is a Technetium (“Tc-99m”) generator that provides the essential nuclear material used by radiopharmacies to radiolabel NEUROLITE, CARDIOLITE and other Tc-99m-based radiopharmaceuticals used in nuclear medicine procedures. TechneLite uses Mo-99 as its active ingredient.
NEUROLITE is an injectable, Tc-99m-labeled imaging agent used with single-photon emission computed tomography (“SPECT”) technology to identify the area within the brain where blood flow has been blocked or reduced due to stroke.
Xenon-133 (“Xenon”) is a radiopharmaceutical gas that is inhaled and used to assess pulmonary function and also to image cerebral blood flow. Our Xenon is manufactured by a third party as a bi-product of Mo-99 production and is processed and finished by us.
CARDIOLITE, also known by its generic name sestamibi, is an injectable, Tc-99m-labeled imaging agent used in myocardial perfusion imaging (“MPI”) procedures to assess blood flow to the muscle of the heart using SPECT. Included in CARDIOLITE revenues are branded CARDIOLITE and generic sestamibi revenues.

Radiopharmaceutical Oncology
Continued Growth of PYLARIFY
PYLARIFY is the leading radiopharmaceutical diagnostic agent indicated for PET imaging of PSMA-positive lesions in men with prostate cancer with suspected metastasis who are candidates for initial definitive therapy and in men with suspected recurrence based on elevated PSA levels. PYLARIFY works by binding to PSMA, a protein that is overexpressed on the surface of more than 90% of primary and metastatic prostate cancer cells. PYLARIFY works with PET/CT technology to produce a combined scan that enables the scan reader to detect and locate the disease.
According to the American Cancer Society, prostate cancer is the second most common cancer in American men - one in eight American men will be diagnosed with prostate cancer in their lifetimes and over 3.3 million American men are living with prostate cancer today. Based on estimates from third-party sources regarding the incidence of prostate cancer in men in the U.S., we believe the current market potential for PSMA PET imaging agents in the U.S. for 2024 could be about 445,000 scans, and the total addressable market by 2029 could be over 700,000 annual scans.
PYLARIFY is manufactured on a diverse, F 18 distributor supply network of PMFs, ensuring convenient and reliable supply. After being made on a cyclotron at a PMF, the F 18 is then combined with certain chemical ingredients in specially designed chemistry synthesis boxes to manufacture PYLARIFY. The finished PYLARIFY is then quality control tested and transferred to a radiopharmacist who prepares and dispenses patient-specific doses of the final product. Because each PMF manufacturing PYLARIFY is deemed by the FDA to be a separate manufacturing site, each is separately approved by the FDA. As of December 31, 2023, we had activated 54 PMF manufacturing sites in our PMF network, up from 37 activated sites as of December 31, 2022. These additional sites provide geographic breadth, out-the-door time flexibility and added optionality within our existing PMF network. Overall, we have achieved broad national distribution of PYLARIFY with customers in 47 of 50 states, the District of Columbia and Puerto Rico.
In addition to our network of commercial PMFs, we also work with academic medical centers in the U.S. that have radioisotope-producing cyclotrons and that have expressed an interest in manufacturing PYLARIFY. For this initiative, we enter into a fee-for-service arrangement under which the academic medical center manufactures F 18 on its cyclotron and completes the manufacturing process for PYLARIFY. PYLARIFY can then be used by the academic medical center itself, and in some cases distributed to other customers under separate purchase agreements.
Our Healthcare Procedure Coding System (“HCPCS”) code, which enables streamlined billing, went into effect as of January 1, 2022. In addition, effective January 1, 2022, the Centers for Medicare and Medicaid Services (“CMS”) granted TPT Status in the hospital outpatient setting for PYLARIFY, enabling traditional Medicare to provide an incremental payment for PET/CT scans performed with PYLARIFY in that setting. TPT Status for PYLARIFY is expected to expire on December 31, 2024.
In July 2023, CMS proposed possible changes to its regulations covering payment for diagnostic radiopharmaceuticals. This included, for the first time since 2008, options for separate payment for diagnostics instead of the current packaged payment following expiration of TPT Status. We, along with numerous industry organizations, submitted comments to CMS. In completing its 2023 rulemaking for the 2024 payment calendar year, CMS recognized the challenges of patient access to diagnostic radiopharmaceuticals and requested feedback on various payment alternatives that could provide separate reimbursement for these items, but the agency did not adopt any of these proposals in the final rule, while stating that it would continue to evaluate this issue in subsequent rulemaking. We plan to submit additional comments to CMS in connection with its 2024 rulemaking for the 2025 payment calendar year.
Our continued growth of PYLARIFY will depend on our ability to clinically and commercially differentiate PYLARIFY from other products on the market and to maintain PYLARIFY as the leading PSMA PET imaging agent in a competitive marketplace. PYLARIFY’s current competition is primarily two Gallium-68 (“Ga-68”)-based PSMA imaging agents, a fluorine-18-based PSMA
7

Table of Contents

imaging agent, and other non-PSMA-based imaging agents commonly referred to as conventional imaging. Continued growth and revenue contribution from PYLARIFY will also depend on our ability to differentiate PYLARIFY in light of the potential loss of TPT Status, including through flexible and dependable access to PYLARIFY nationally, a best in class customer experience and through long-term strategic contracts.
We actively pursue patents in connection with PYLARIFY, both in the U.S. and internationally. In the U.S. for PYLARIFY, we have five Orange Book-listed patents, including composition of matter patents, the last of which expires in 2037. Outside of the U.S., we have, and are currently pursuing, additional PYLARIFY patents to obtain similar patent protection as in the U.S.
See Part I, Item 1A. “Risk Factors” for information regarding certain risks associated with PYLARIFY and Part II, Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations - Comparison of the Periods Ended December 31, 2023 and 2022 - Revenues” for further information on total revenue contributed by PYLARIFY since its approval.
Precision Diagnostics
Continued Growth of DEFINITY
DEFINITY is the leading ultrasound enhancing agent in the U.S. and is indicated for use in patients with suboptimal echocardiograms to opacify the left ventricular chamber and to improve the delineation of the left ventricular endocardial border. Numerous patient conditions can decrease the quality of images of the left ventricle, the primary pumping chamber of the heart. The term DEFINITY includes its activated and non-activated forms and the two formulations it is commercially available in; one that requires refrigerated storage and one that we have branded as DEFINITY RT that may be stored at room temperature.
DEFINITY is a clear, colorless, sterile liquid that, upon activation in a VIALMIX or VIALMIX RFID, medical devices specifically designed for DEFINITY, becomes a homogenous, opaque, milky white injectable suspension of perflutren-containing lipid microspheres. After activation and intravenous injection, DEFINITY opacifies the left ventricular chamber and improves the delineation of the left ventricular endocardial border, or innermost layer of tissue that lines the chamber of the left ventricle. Better visualization of the left ventricle allows clinicians to make more informed decisions about disease status.
Based on estimates from third party sources, we believe there were approximately 29 to 30 million echocardiograms performed in the U.S. in 2022 (the latest time period for which full year data is available). Assuming that between 20% and 30% of echocardiograms produce suboptimal images, as stated in the clinical literature, we estimate that approximately 6 to 9 million echocardiograms in 2022 produced suboptimal images.
Since its launch in 2001, DEFINITY has been used in imaging procedures in more than 25 million studies throughout the world. We estimate that, as of December 31, 2023, DEFINITY had over 80% share of the U.S. segment for ultrasound enhancing agents in echocardiography procedures. DEFINITY currently competes with two other FDA-approved ultrasound enhancing agents, as well as echocardiography without the use of ultrasound enhancing agents and non-echocardiography imaging modalities. DEFINITY and the other FDA-approved ultrasound enhancing agents all carry an FDA-required boxed warning, which has been modified over time, to notify physicians and patients about potentially serious safety concerns or risks posed by the products. See Part I, Item 1A. “Risk Factors-Ultrasound enhancing agents may cause side effects which could limit our ability to sell DEFINITY.”
We continue to actively pursue additional patents in connection with DEFINITY and DEFINITY RT, both in the U.S. and internationally. In the U.S. for DEFINITY, we have six Orange Book-listed method-of-use patents, one of which expires in 2035 and five of which expire in 2037, as well as additional manufacturing patents that are not Orange Book-listed expiring in 2037. In the U.S. for DEFINITY RT, we have eight Orange Book-listed patents, including two composition of matter patents which expire in 2035. The Orange Book-listed patents include a patent on the use of VIALMIX RFID (see below), which expires in 2037; we have submitted additional VIALMIX RFID patent applications in major markets throughout the world.
Even though our longest duration Orange Book-listed DEFINITY patent extends until March 2037, because our Orange Book-listed composition of matter patent expired in June 2019, we may face generic DEFINITY challenges in the near to intermediate term. See “Intellectual Property – Patents” below.
As noted above, DEFINITY is activated through the use of medical devices branded as VIALMIX and VIALMIX RFID. The activation rate and time are controlled by VIALMIX RFID through the use of radio-frequency identification technology (“RFID”) to ensure reproducible activation of DEFINITY. The RFID tag, which is affixed to the vial label, enables the DEFINITY vial to be appropriately activated with the VIALMIX RFID activation device.
To manufacture DEFINITY that requires refrigeration, historically, we have relied on Jubilant HollisterStier (“JHS”) as a significant supplier. We constructed a specialized in-house manufacturing facility at our North Billerica campus for purposes of

Table of Contents

producing this formulation of DEFINITY and, potentially, other sterile vial products. On February 22, 2022, we received FDA approval of our supplemental new drug application (“sNDA”), authorizing commercial manufacturing of this formulation of DEFINITY at our new facility. We believe this investment provides supply chain redundancy, improved flexibility and reduced costs in a potentially more price competitive environment.
See Part I, Item 1A. “Risk Factors” for information regarding certain risks associated with DEFINITY and Part II, Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations - Comparison of the Periods Ended December 31, 2023 and 2022 - Revenues” for further information on revenue contributed by DEFINITY.
TechneLite
TechneLite is a self-contained system or generator of Tc-99m, a radioactive isotope with a six hour half-life, used by radiopharmacies to prepare various nuclear imaging agents. Tc-99m results from the radioactive decay of Mo-99, itself a radioisotope with a 66-hour half-life sourced in our supply chain in nuclear research reactors located in Belgium, South Africa and Australia from enriched uranium. The TechneLite generator is a self-contained system that houses a vertical glass column at its core that contains Mo-99, which degrades to Tc-99m. During our manufacturing process, Mo-99 is added to the column within the generator where it is adsorbed onto alumina powder. The column is sterilized, enclosed in a lead shield and further sealed in a cylindrical plastic container, which is then immediately shipped to our radiopharmacy customers. Because of the short half-lives of Mo-99 and Tc-99m, radiopharmacies typically purchase TechneLite generators on a weekly basis pursuant to standing orders.
The Tc-99m produced by our TechneLite generator is the medical radioisotope that can be attached to a number of imaging agents, including our own NEUROLITE and CARDIOLITE products, during the radiolabeling process. To radiolabel a Tc-99m-based radiopharmaceutical, a vial of sterile saline and a vacuum vial are each affixed to the top of a TechneLite generator. The sterile saline is pulled through the generator where it attracts Tc-99m resulting from the radioactive decay of Mo-99 within the generator column. The Tc-99m-containing radioactive saline is then pulled into a vacuum vial and subsequently combined by a radiopharmacist with the applicable imaging agent, which allows the preparation of individual patient-specific radiolabeled imaging agent doses. When administered, the imaging agent binds to specific tissues or organs for a period of time, enabling the Tc-99m to illuminate the functional health of the imaged tissues or organs in a diagnostic image. Our ability to produce and market TechneLite is highly dependent on our supply of Mo-99. See “Raw Materials and Supply Relationships—Molybdenum-99” below.
TechneLite is currently marketed primarily in the U.S., Canada, Central America and South America, largely to radiopharmacies that prepare unit doses of radiopharmaceutical imaging agents and ship these preparations directly to hospitals for administration to patients. In the U.S., we have supply contracts with large radiopharmacy groups, including PharmaLogic Holdings Corp (“PharmaLogic”), Cardinal Health (“Cardinal”), RLS (USA) Inc. (previously GE Healthcare) (“RLS”) and United Pharmacy Partners (“UPPI”). We also supply generators on a purchase order basis to other customers. We estimate that TechneLite had approximately one third of the U.S. generator market as of December 31, 2023, competing primarily with Tc-99m-based generators produced by Curium.
We believe that our substantial capital investments in our TechneLite production line and our extensive experience in complying with the stringent regulatory requirements for the handling of nuclear materials, create significant and sustainable competitive advantages for us in generator manufacturing and distribution. Given our significant know-how and trade secrets associated with the methods of manufacturing and assembling the TechneLite generator, we believe we have a substantial amount of valuable and defensible proprietary intellectual property associated with the product. In addition, TechneLite has patent protection in the U.S. and various foreign countries on certain component technology currently until 2029, and we are pursuing additional patent protection in the U.S. and world-wide on other component technology that, if granted, would expire in 2040.
See Part II, Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations - Comparison of the Periods Ended December 31, 2023 and 2022 - Revenues” for further information on revenue contributed by TechneLite.

As we continue to pursue expanding strategic partnerships, our Pharma Solutions activities in oncology include:
Prostate Cancer – We collaborate with pharmaceutical companies developing therapies and diagnostics in prostate cancer.
In July 2023, Curium (our licensee that is developing and commercializing piflufolastat F 18 in Europe) announced that it received marketing authorization for piflufolastat F 18, under the name PYLCLARI, from the European Commission. In addition, we previously entered into an agreement with Curium to add PYLARIFY to its U.S. ECLIPSE trial, a multi-center, open-label, randomized Phase 3 trial comparing the safety and efficacy of Curium’s PSMA-targeted therapeutic versus hormone therapy in patients mCRPC. PYLARIFY will be used to determine PSMA-avidity as part of patient selection.
We have also entered into several other separate agreements, including with RefleXion Medical, Inc., POINT and Regeneron Pharmaceuticals, Inc., under which we supply PYLARIFY in connection with their clinical trials and with the Prostate Cancer Clinical Trial Consortium (“PCCTC”), a premier multicenter clinical research organization that specializes in prostate cancer research. The intent of the strategic collaboration with PCCTC is to integrate our artificial intelligence (“AI”) platform into PCCTC studies to advance the development and validation of novel AI-enabled biomarkers.
Immuno-Oncology - We entered into a strategic collaboration and license agreement with NanoMab Technology Limited (“NanoMab”), a privately-held biopharmaceutical company focused on the development of next generation radiopharmaceuticals for cancer precision medicine, to develop NM-01, a novel technetium-99m SPECT imaging agent under development to assess PD-L1 expression in cancer cells. In connection with the collaboration, NanoMab recently completed a Phase 2 clinical trial at King’s College London. The Phase 2 clinical trial was an open-label, single-arm trial in non-small cell lung cancer patients. The primary endpoint was the assessment of PD-L1 expression in primary tumor and metastatic lesions by NM-01 compared to immunohistochemistry. Other objectives were aimed at quantifying intra- and inter-tumoral heterogeneity of PD-L1 expression by NM-01, as well as establishing correlations with other diagnostic procedures. We expect results from the clinical trial to be presented at an upcoming medical congress.
Pan-Oncology - In collaboration with Ratio Therapeutics LLC (“Ratio”) (previously Noria Therapeutics, Inc.), we are developing LNTH-1363S, a novel copper-64 labeled PET imaging agent, targeting fibroblast activation protein alpha. We believe this diagnostic agent candidate could have broad potential applicability and use in oncology and also in inflammatory diseases. Recently, in collaboration with Ratio, we completed a Phase 1 study for LNTH-1363S to evaluate the pharmacokinetics, biodistribution and radiation dosimetry in adult healthy volunteers. We plan to initiate a Phase 1/2a study in patients in 2024.
Microbubble Franchise
In addition, we continue to seek to optimize our microbubble platform through new collaborations. Some of our microbubble collaborations are with the following parties: (i) Cerevast Medical, Inc. (“Cerevast”), in which our microbubbles will be used in connection with Cerevast’s ocular ultrasound device to improve blood flow in occluded retinal veins in the eye; (ii) CarThera SAS (“CarThera”), for the use of our microbubbles in combination with SonoCloud, a proprietary implantable device in development for the treatment of recurrent glioblastoma; (iii) Insightec Ltd. (“Insightec”), which will use our microbubbles in connection with the development of Insightec’s transcranial guided focused ultrasound device for the treatment of glioblastoma as well as other neurodegenerative conditions; (iv) Allegheny Health Network (“AHN”) which will use our microbubbles in combination with AHN’s ultrasound-assisted non-viral gene transfer technology for the development of a proposed treatment of xerostomia; and (v) SonoThera, Inc. (“SonoThera”), who will use our microbubbles in combination with their ultrasound-guided, non-viral, gene therapy platform and treatments.
In March 2012, we entered into a development and distribution arrangement with China Resources Double-Crane (“Double-Crane”) for DEFINITY in China, Hong Kong and Macau. Double-Crane has conducted on our behalf three confirmatory clinical trials in pursuit of cardiac, liver and kidney imaging indications, as well as one small pharmacokinetic study. In November 2022, we announced the approval of our Import Drug License application with the National Medical Products Administration (“NMPA”) for the use of DEFINITY in patients with suboptimal conventional echocardiography and to better identify the left ventricular endocardial border. Double-Crane is responsible for obtaining adequate coding, coverage and payment and commercializing DEFINITY in China under a local brand name. Double-Crane is also in the process of analyzing the clinical results relating to liver and kidney indications and will also work with us to prepare an Import Drug License application for those indications, as appropriate.

MK-6240
MK-6240 is an investigational clinical stage F 18-labeled PET imaging development candidate designed to detect Tau protein in the form of neurofibrillary tangles in the brains of patients with known or suspected Alzheimer’s disease. MK-6240 is being used as a
10

Table of Contents

biomarker in more than 90 active clinical trials for Alzheimer’s disease therapeutic candidates. Research revenue related to MK-6240 is derived from the use of MK-6240 in those clinical trials and includes milestone and dose-related payments.
RELISTOR
On August 2, 2023, we sold our right to our RELISTOR net sales royalties under our license agreement with Bausch; we retained the rights to future sales-based milestone payments. Pursuant to our license agreement with Bausch, we are eligible to receive one-time sales milestone payments upon achievement of specified U.S. net sales targets, including:

U.S. Net Sales Levels in any Single Calendar Year
Payment ($)
(In thousands)
In excess of $150 million
15,000
In excess of $200 million
20,000
In excess of $300 million
30,000
In excess of $750 million
50,000
In excess of $1 billion
75,000
Each sales milestone payment is payable one time only, regardless of the number of times the condition is satisfied, and all five remaining payments could be made within the same calendar year. During the fourth quarter of 2023, the Company earned the $15.0 million sales-based milestone payment listed above.
aBSI
aBSI automatically calculates the disease burden of prostate cancer by detecting and classifying bone scan tracer uptakes as metastatic or benign lesions using an artificial neural network. The cloud based aBSI was made available for clinical use in the U.S. on August 5, 2019. In February 2020, Progenics received European Conformity Marking (“CE marking”) for the standalone workstation model of aBSI, meeting the quality standards set by the European Economic Area. In September 2020, the FDA granted 510(k) clearance for the use of aBSI as software-as-a-medical device on a GE Healthcare imaging system.
PYLARIFY AI
PYLARIFY AI is artificial intelligence medical device software that is designed to allow healthcare professionals and researchers to perform standardized quantitative assessment of PSMA PET/CT images in prostate cancer, including those images obtained by using PYLARIFY. PYLARIFY AI has demonstrated improved consistency, accuracy and efficiency in quantitative assessment of PSMA PET/CT. The technology analyzes the PET/CT image to segment anatomical regions, including 51 bones and 12 soft tissue organs. This image segmentation enables automated localization, detection and quantification of potential PSMA-avid lesions in the PET/CT image, which is incorporated into a standardized report for physicians. PYLARIFY AI can be deployed either as a secure web cloud application or within the secure firewall of the institution on a local server. Once deployed, the adaptive application can be integrated into an institution’s existing clinical workflow, delivering a unique combination of clinical utility and technical flexibility. Our subsidiary, EXINI, was granted 510(k) clearance by the FDA in the U.S. and received a CE marking in Europe for aPROMISE. We commercially launched aPROMISE under the name PYLARIFY AI in the U.S. in November 2021 and the FDA granted us an additional 510(k) clearance during the second quarter of 2022.
[18F] flurpiridaz
GE Healthcare Agreement – In 2017, we entered into a definitive, exclusive Collaboration and License Agreement with GE Healthcare for the continued Phase 3 development and worldwide commercialization of flurpiridaz, a fluorine 18-based PET MPI agent designed to assess blood flow to the heart in patients suspected of coronary artery disease (“CAD”). Under our agreement, GE Healthcare will complete the development of flurpiridaz, pursue worldwide regulatory approvals, and, if successful, lead a worldwide launch and commercialization of the agent, with us collaborating on both development and commercialization through a joint steering committee. We also have retained the right to co-promote the agent in the U.S. GE Healthcare’s development plan initially focuses on obtaining regulatory approval in the U.S., Japan, Europe and Canada. Under the agreement, we received an upfront cash payment of $5.0 million and are eligible to receive up to $60.0 million in regulatory and sales milestone payments, tiered double-digit royalties on U.S. sales, and mid-single digit royalties on sales outside of the U.S. In September 2022, we announced with GE Healthcare that the second Phase 3 clinical trial had met its co-primary endpoints of exceeding a 60% threshold for both sensitivity and specificity for detecting CAD. The findings,
11

Table of Contents

shared at an American Society of Nuclear Cardiology conference, also indicated that cardiac PET imaging with flurpiridaz demonstrated higher diagnostic efficacy and image quality in patients with suspected CAD, compared with SPECT MPI, the predominant procedure currently used in nuclear cardiology. GE Healthcare recently announced that it had filed an NDA with the FDA for flurpiridaz. Assuming regulatory approval, we anticipate commercialization by GE Healthcare beginning in the second half of 2024.
See Part I, Item 1A. “Risk Factors” for information regarding certain risks associated with our strategic activities.
Our Clinical Development Candidates
In addition to our commercial products and strategic partnerships with third parties, we also have ongoing clinical development programs, including, among others, the following:
PNT2002 is an investigational PSMA-targeted radiopharmaceutical therapy for the treatment of mCRPC. On December 18, 2023, we announced positive topline results from SPLASH, the Phase 3 registrational trial for PNT2002 designed to evaluate superiority to the standard of care in mCRPC pre-chemotherapy patients who have failed one androgen receptor pathway inhibitor.
PNT2003 is an investigational SSTR therapy with non-carrier added lutetium-177, which is in registration to treat patients with SSTR-positive neuroendocrine tumors. On January 11, 2024, we announced that our ANDA for PNT2003 was accepted for filing by the FDA. On January 26, 2024, we were sued in the United States District Court for the District of Delaware by Advanced Accelerator Applications USA, Inc. and Advanced Accelerator Applications SA, each a Novartis entity, for patent infringement in response to the filing of our ANDA and Paragraph IV certification, consistent with the process established by the Hatch-Waxman Act.
MK-6240 is an investigational second-generation F 18-labeled PET imaging agent that targets Tau tangles in Alzheimer’s disease. MK-6240 is currently being used in more than 90 active clinical trials for several Alzheimer’s disease therapeutic candidates being developed.
LNTH-1363S is an investigational fibroblast activation protein, alpha targeted, copper-64 labeled PET imaging agent candidate that we believe could have broad potential imaging applicability and use in oncology. Recently, we completed a Phase 1 study for LNTH-1363S to evaluate the pharmacokinetics, biodistribution and radiation dosimetry in adult healthy volunteers.
1095 (also known as 131 I-MIP-1095) is an investigational PSMA-targeted iodine-131-labeled small molecule that is designed to deliver a dose of beta radiation directly to prostate cancer cells with minimal impact on the surrounding healthy tissues. We enrolled the last patient in our ARROW Phase 2 study during the second quarter of 2022. Patients in this study will be followed for one year after their first treatment for all efficacy endpoints and survival and safety data will be collected for an additional year.
For the years ended December 31, 2023, 2022 and 2021, we invested $77.7 million, $311.7 million and $45.0 million in research and development (“R&D”), respectively, primarily related to our clinical development candidates. In addition to our clinical development group, our R&D team also includes our Medical Affairs and Medical Information functions, which educate physicians on the scientific aspects of our commercial products and the approved indications.

With respect to our medical devices:
Progenics received CE marking for the standalone workstation model of aBSI, meeting the quality standards set by the European Economic Area. In September 2020, the FDA granted 510(k) clearance for the use of aBSI as software-as-a-medical device on a GE Healthcare imaging system.
EXINI was granted 510(k) clearance by the FDA in the U.S. and received CE marking in Europe for aPROMISE. We launched aPROMISE under the name PYLARIFY AI in the U.S.
PYLARIFY sales are generated in the U.S. through an internal PYLARIFY sales team, as well as a sales team at some of our PMF partners. Sales of DEFINITY are generated in the U.S. through an internal DEFINITY sales team. While a small portion of our nuclear imaging product sales in the U.S. are generated through our internal sales force to hospitals and clinics that maintain their own in-house radiopharmaceutical preparation capabilities, we primarily sell our nuclear imaging products, including TechneLite, NEUROLITE, Xenon, and CARDIOLITE, to large radiopharmacy chains. We have licensed RELISTOR to Bausch, and while we have sold the right to our RELISTOR net sales royalties under our license agreement, we have retained the rights to future sales-based milestone payments generated by Bausch.
Seasonality
We have some modest seasonality for our products as patients may seek to schedule diagnostic imaging and other procedures less frequently during the summer vacation months and over the year-end holidays.
Customers
No customer accounted for greater than 10% of revenues for the years ended December 31, 2023, 2022, and 2021.

Table of Contents

Backlog
Our backlog consists of orders for which a delivery schedule within the next twelve months has been specified. Orders included in backlog may be canceled or rescheduled by customers at any time with the exception of TechneLite orders. For TechneLite, customers must provide us with four weeks advanced notice to cancel an order. We do not believe that our backlog at any particular time is meaningful because it has historically been immaterial relative to our consolidated revenues and is not necessarily indicative of future revenues for any given period.
Competition
We believe that our key product characteristics, such as proven efficacy, reliability and safety, coupled with our core competencies, such as our efficient manufacturing processes, our established distribution network, our experienced field sales organization and our customer service focus, are important factors that distinguish us from our competitors.
The markets for our products are highly competitive and continually evolving. Our principal competitors for our current commercial products and leading clinical development candidates include large, global companies that are more diversified than we are and that have substantial financial, manufacturing, sales and marketing, distribution and other resources.
For PYLARIFY, our principal competitors are currently Telix Pharmaceuticals Limited, Novartis AG, and Blue Earth Diagonstics Ltd. (“Blue Earth”), a subsidiary of Bracco Diagnostics Inc. (“Bracco”).
For DEFINITY, our competitors currently include GE Healthcare and Bracco.
For a number of our SPECT radiopharmaceutical commercial products, our competitors currently include Curium, GE Healthcare, Bracco and Jubilant Life Sciences, an affiliate of JHS and Jubilant Radiopharma, and potentially BWXT Medical.
The markets into which any of our product candidates would be launched, if approved, are also highly competitive and continually evolving.
For PNT2002 and 1095, our principal competitors may include Novartis AG; Telix Pharmaceuticals Limited; and Curium, each of which has commercialized products or product candidates in advanced clinical stage of development.
For PNT2003, our principal competitor may include Novartis AG; ITM Radiopharma; and RayzeBio (under agreement to be acquired by Bristoll Meyers Squibb), each of which has commercialized products or product candidates in advanced clinical stage development.
For MK-6240, our principal competitors may include Eli Lilly and Company and Life Molecular Imaging, each of which has commercialized products or product candidates in advanced clinical stage of development.
For LNTH-1363S, our principal competitors may include Sofie Bioscience; GE Healthcare; and Novartis AG, each of which has product candidates in clinical stage of development.
We cannot anticipate the actions of our current or future competitors in the same or competing therapeutic and diagnostic modalities, such as significant price reductions on products that are comparable to our own, development of new products or other technologies that are more cost-effective or have superior performance than our current products or the introduction of generic versions after our proprietary products lose their patent protection. In addition, distributors of our products could attempt to shift end-users to competing modalities and products, or bundle the sale of a portfolio of products, to the detriment of our specific products. Our current or future products could be rendered obsolete or uneconomical as a result of these activities.
Further, the radiopharmaceutical and biopharmaceutical industry continues to evolve strategically, with several market participants recently sold. In addition, the supply-demand dynamics of the industry are complex because of large market positions of some participants, legacy businesses, government subsidies (in particular, relating to the manufacture of radioisotopes), government reimbursement policies, such as TPT Status, and group purchasing arrangements. We cannot predict what impact new owners and new operators may have on the strategic decision-making of our competitors, customers and suppliers.
Raw Materials and Supply Relationships
We rely on certain raw materials and supplies to produce our products. Due to the specialized nature of our products and the limited, and sometimes intermittent, supply of raw materials available in the market, we have established relationships with several key suppliers. For the year ended December 31, 2023, our largest suppliers of raw materials and supplies were Institute for Radioelements (“IRE”), the Australian Nuclear Science and Technology Organisation (“ANSTO”) and NTP Radioisotopes (“NTP”), which, in the aggregate, accounted for approximately 9.3% of our total purchases.
14

Table of Contents

Molybdenum-99
Our TechneLite, CARDIOLITE and NEUROLITE products all rely on Mo-99, the radioisotope which is produced by bombarding uranium with neutrons in research reactors. With a 66-hour half-life, Mo-99 decays into, among other things, Tc-99m, another radioisotope with a half-life of six hours. Tc-99m is the isotope that is attached to radiopharmaceuticals, including our own NEUROLITE and CARDIOLITE, during the labeling process and is the most common radioisotope used for medical diagnostic imaging purposes.
We currently purchase finished Mo-99 from three of the four main processing sites in the world, namely IRE in Belgium, NTP in South Africa and ANSTO in Australia. These processing sites provide us Mo-99 from five of the six main Mo-99-producing reactors in the world, namely BR2 in Belgium, LVR-15 in the Czech Republic, HFR in The Netherlands, SAFARI in South Africa and OPAL in Australia.
Our agreement with IRE (the “IRE Agreement”) contains minimum percentage volume requirements and unit pricing. The IRE Agreement also requires IRE to provide certain favorable allocations of Mo-99 during periods of supply shortage or failure. The IRE Agreement allows for termination upon the occurrence of certain events, including failure by IRE to provide our required amount of Mo-99, material breach of any provision by either party, bankruptcy by either party or force majeure events. The IRE Agreement expires on December 31, 2024, and automatically renews on an annual basis thereafter, subject to prior notice of non-renewal by either party.
Our agreement with NTP (the “NTP Agreement”), with NTP acting for itself and on behalf of its subcontractor ANSTO, specifies our percentage purchase requirements and unit pricing, and provides for the supply of Mo-99. The NTP Agreement allows for termination upon the occurrence of certain events, including failure by NTP to provide our required amount of Mo-99, material breach of any provision by either party, bankruptcy by either party or force majeure events. The NTP Agreement expires on December 31, 2024.
Although we have a globally diverse Mo-99 supply with IRE in Belgium, NTP in South Africa, and ANSTO in Australia, we still face supplier and logistical challenges in our Mo-99 supply chain. When one supplier experiences outages, we generally rely on Mo-99 supply from the other suppliers to limit the impact of the outages. We believe we effectively manage these various supply chain challenges, but depending on reactor and processor schedules and operations, at times we have not been able to fill some or all of the demand for our TechneLite generators on certain manufacturing days. A prolonged disruption of service from one of our three Mo-99 processing sites or one of their main Mo-99-producing reactors could have a substantial negative effect on our business, results of operations, financial condition and cash flows.
Xenon
Xenon is a by-product of the Mo-99 production process. Under a strategic agreement entered into in 2021, we receive from IRE bulk unprocessed Xenon, which we process and finish for our customers at our North Billerica, Massachusetts manufacturing facility. That contract runs through December 31, 2025, with auto-renewal provisions and is terminable upon notice of non-renewal. Until we can qualify an additional source of bulk unprocessed Xenon, we will rely on IRE as a sole source provider.
Other Materials
We have additional supply arrangements for active pharmaceutical ingredients, excipients, packaging materials and other materials and components, none of which are exclusive, but a number of which are sole source, and all of which we currently believe are either in good standing or replaceable without any material disruption to our business.
See Part I, Item 1A. “Risk Factors” for information regarding certain risks associated with our raw materials and supply arrangements.
Manufacturing
The commercial manufacture of PYLARIFY required us to create a field-based network of specialized PMFs with radioisotope-producing cyclotrons. The radioisotope used in PYLARIFY is F 18, which has a 110 minute half-life, requiring that this agent be manufactured and distributed rapidly to end-users. After being made on a cyclotron at a PMF, the F 18 is then combined with certain chemical ingredients in specially designed chemistry synthesis boxes to manufacture PYLARIFY. The finished PYLARIFY is then quality control tested and transferred to a radiopharmacist who prepares and dispenses patient-specific doses from the final product. Because each of the PMFs manufacturing PYLARIFY is deemed by the FDA to be a separate manufacturing site, each requires separate FDA approval.
We have a specialized in-house manufacturing facility at our North Billerica campus for purposes of producing the formulation of DEFINITY that requires refrigerated storage and, potentially, other sterile vial products. On February 22, 2022, we received FDA
15

Table of Contents

approval of our sNDA, authorizing commercial manufacturing of DEFINITY at our new facility. DEFINITY manufactured at this facility became commercially available on February 23, 2022. We believe this investment provides supply chain redundancy, improved flexibility and reduced costs in a potentially more price competitive environment.
We also manufacture TechneLite on an automated production line and we process and finish Xenon on a hot cell line at our North Billerica, Massachusetts facility.
We manufacture, finish and distribute our radiopharmaceutical products on a just-in-time basis, and supply our customers with these products either by next day delivery services or by either ground or air custom logistics. We believe that our substantial capital investments in our automated generator production line and our other manufacturing assets, which we have made over the years, and our extensive experience in complying with the stringent regulatory requirements for the handling of nuclear materials and operations in a highly regulated environment, create significant and sustainable competitive advantages for us.
In addition to our in-house manufacturing capabilities, a substantial portion of our products are manufactured by third party contract manufacturing organizations, and in certain instances, we rely on them for sole source manufacturing. To ensure the quality of the products that are manufactured by third parties, the key raw materials used in those products are first sent to our North Billerica, Massachusetts facility, where we test them prior to the third party manufacturing of the final product. For many of our products, after the final products are manufactured, they are sent back to us for final quality control testing, and then we ship them to our customers. We have expertise in the design, development and validation of complex manufacturing systems and processes, and our strong execution and quality control culture supports the just-in-time manufacturing model at our facilities.
Manufacturing and Supply Arrangements
We currently have the following technology transfer and manufacturing and supply agreements in place for some of our major products:
PYLARIFY—We have entered into commercial supply agreements with different PMF networks. Our agreements with our PMF networks allow for the termination upon the occurrence of specified events, including material breach or bankruptcy by either party, and have various termination dates generally terminating between 2025 and 2030 and are subject to renewal provisions.
DEFINITY, CARDIOLITE and NEUROLITE—In February 2022, we entered into a Manufacturing and Supply Agreement with JHS, for the manufacture of DEFINITY, CARDIOLITE, NEUROLITE and evacuation vials, the latter being an ancillary component for our TechneLite generators. The agreement expires on December 31, 2027, and can be renewed upon mutual consent. The agreement allows for termination upon the occurrence of certain events such as a material breach or default by either party, or bankruptcy by either party. The agreement also requires us to order from JHS a specified minimum percentage of our requirements for DEFINITY and fixed quantities of CARDIOLITE and NEUROLITE each year during the contract term.
See Part I, Item 1A. “Risk Factors” for information regarding certain risks associated with our manufacturing and supply relationships.
Intellectual Property
Patents, trademarks and other intellectual property rights, both in the U.S. and foreign countries, are very important to our business. We also rely on trade secrets, manufacturing know-how, technological innovations, licensing agreements and confidentiality agreements to maintain and improve our competitive position. We review third party proprietary rights, including patents and patent applications, as available, in an effort to develop an effective intellectual property strategy, avoid infringement of third party proprietary rights, identify licensing opportunities and monitor the intellectual property owned by others. Our ability to enforce, defend and protect our intellectual property rights may be limited in certain countries outside the U.S., which could make it easier for competitors to capture market position in those countries by utilizing technologies that are similar to those developed or licensed by us. Competitors also may harm our sales by designing products that mirror the capabilities of our products or technology without infringing our intellectual property rights. If we do not obtain sufficient protection for our intellectual property, or if we are unable to effectively enforce or defend our intellectual property rights or our freedom to operate, our competitiveness could be impaired, which would limit our growth and future revenue. If we elect to enforce our intellectual property rights, or are required to defend our rights, we could incur significant litigation expense.

Patents
We actively seek to protect the proprietary technology that we consider important to our business, including chemical species, compositions and formulations, their methods of use and processes for their manufacture, as new intellectual property is developed. In addition to seeking patent protection in the U.S., we file patent applications in numerous foreign countries in order to further protect the inventions that we consider important to the development of our international business. We also rely upon trade secrets and contracts to protect our proprietary information.
We have patent protection on certain of our commercial products and clinical development candidates. We typically seek patent protection in major markets around the world, including, among others, the U.S., Canada, Western Europe, Asia, Central America and South America. All patent terms described below are presented without giving effect to any applicable patent term adjustments or regulatory extensions.
PYLARIFY - We actively pursue patents in connection with PYLARIFY, both in the U.S. and internationally. In the U.S. for PYLARIFY, we have five Orange Book-listed patents, including composition of matter patents, the last of which expire in 2037. Outside of the U.S., we have, and are currently pursuing, additional PYLARIFY patents to obtain similar patent protection as in the U.S.
DEFINITY - We continue to actively pursue additional patents in connection with DEFINITY and DEFINITY RT, both in the U.S. and internationally. In the U.S. for DEFINITY, we have six Orange Book-listed method-of-use patents, one of which expires in 2035 and five of which expire in 2037, as well as additional manufacturing patents that are not Orange Book-listed expiring in 2037. In the U.S. for DEFINITY RT, we have eight Orange Book-listed patents, including two composition of matter patents which expire in 2035. Outside of the U.S., we are currently pursuing additional DEFINITY and DEFINITY RT patents to obtain similar patent protection as in the U.S. The Orange Book-listed patents include a patent on the use of VIALMIX RFID which expires in 2037; additional VIALMIX RFID patent applications have been submitted in major markets throughout the world.
Even though our longest duration Orange Book-listed DEFINITY patent extends until March 2037, because our Orange Book-listed composition of matter patent expired in June 2019, we may face generic DEFINITY challengers in the near to intermediate term. Under the Hatch-Waxman Act, the FDA can approve ANDAs for generic versions of drugs if the ANDA applicant demonstrates, among other things, that (i) its generic candidate is the same as the innovator product by establishing bioequivalence and providing relevant chemistry, manufacturing and product data, and (ii) either the marketing of that generic candidate does not infringe the Orange Book-listed patent(s) or the Orange Book-listed patent(s) is invalid. Similarly, the FDA can approve a Section 505(b)(2) NDA from an applicant that relies on some of the information required for marketing approval to come from studies which the applicant does not own or have a legal right of reference. With respect to the Orange Book-listed patent(s) covering an innovator product, the ANDA applicant or the Section 505(b)(2) applicant (if relying on studies related to the innovator product) (together, the “Applicant”) must give a notice (a “Notice”) to the innovator of its certification that its generic candidate will not infringe the innovator’s Orange Book-listed patent(s) or that the Orange Book-listed patent(s) is invalid. The innovator can then file suit against the Applicant within 45 days of receiving the Notice, and FDA approval to commercialize the generic candidate will be stayed (that is, delayed) for up to 30 months (measured from the date on which a Notice is received) while the patent dispute between the innovator and the Applicant is resolved in court. The 30-month stay could potentially expire sooner if the courts determine that no infringement had occurred or that the challenged Orange Book-listed patent is invalid or if the parties otherwise settle their dispute. Submission of an ANDA with a Paragraph IV certification can result in protracted and expensive patent litigation.
As of the date of filing of this Annual Report on Form 10-K, we have not received any Notice from an Applicant. If we were to (i) receive any such Notice in the future, (ii) bring a patent infringement suit against the Applicant within 45 days of receiving that Notice, and (iii) successfully obtain the full 30-month stay, then the Applicant would be precluded from commercializing a generic version of DEFINITY prior to the expiration of that 30-month stay period and, potentially, thereafter, depending on how the patent dispute is resolved. Solely by way of example and not based on any knowledge we currently have, if we received a Notice from an Applicant in March 2024 and the full 30-month stay were obtained, then the Applicant would be precluded from commercialization until at least September 2026. If we received a Notice some number of months in the future and the full 30-month stay were obtained, the commercialization date would roll forward in the future by the same number of months. In the event a 505(b)(2) applicant does not rely on studies related to the innovator product, the 30-month stay would not apply, but additional clinical trials may be required.
TechneLite - We currently own patents in the U.S. and various foreign countries on certain component technology expiring in 2029, and we are pursuing additional patent protection in the U.S. and world-wide on other component technology that, if granted, would expire in 2040. In addition, given the significant know-how and trade secrets associated with the methods of manufacturing and assembling the TechneLite generator, we believe we have a substantial amount of valuable and defensible proprietary intellectual property associated with the product.

LNTH-1363S - We exclusively license patent applications directed to compositions of matter and methods of use of LNTH-1363S. If granted, the last patent will expire in 2043.
NM-01- We exclusively license in the field of imaging, patents and applications directed to compositions of matter of NM-01. The granted U.S. patents expire in 2037.
1404 - We own patents relating to composition of matter, as well as technetium-99 labeled forms of 1404 expiring in the U.S. from 2029 to 2030, and expiring worldwide in 2029.
In addition to patents, we rely, where necessary, upon unpatented trade secrets and know-how, proprietary information and continuing technological innovation to develop and maintain our competitive position. We seek to protect our proprietary information, in part, using confidentiality agreements with our collaborators, employees, consultants and other third parties and invention assignment agreements with our employees.
In addition, we license third-party technologies and other intellectual property rights that are incorporated into some elements of our drug discovery and development efforts. Some of these licenses are material to our business – for example, the licenses on the PYLARIFY patent family from Johns Hopkins University (“JHU”).
See Part I, Item 1A. “Risk Factors” for information regarding certain risks associated with our intellectual property.
Regulatory Matters
Food and Drug Laws
The development, manufacture and commercialization of our products are subject to comprehensive governmental regulation both within and outside the U.S. A number of factors substantially increase the time, difficulty and costs incurred in obtaining and maintaining the approval to market newly developed and existing products. These factors include governmental regulation, such as detailed inspection of and controls over research and laboratory procedures, clinical trials, manufacturing, marketing, advertising and promotion, sampling, distribution, import and export, record keeping and storage and disposal practices, together with various post-marketing requirements. Governmental regulatory actions can result in the seizure or recall of products, suspension or revocation of the authority necessary for their production and sale as well as other civil or criminal sanctions.

Table of Contents

Our activities related to the development, manufacture, packaging or repackaging of our products subject us to a wide variety of laws and regulations. We are required to register for permits and/or licenses with, seek approvals from and comply with operating and security standards of, the FDA, the U.S. Nuclear Regulatory Commission (“NRC”), the U.S. Department of Health and Human Services (“HHS”), Health Canada, the European Medicines Agency (“EMA”), the U.K. Medicines and Healthcare Products Regulatory Agency (“MHRA”), the NMPA and various state and provincial boards of pharmacy, state and provincial controlled substance agencies, state and provincial health departments and/or comparable state and provincial agencies, as well as foreign agencies, and certain accrediting bodies depending upon the type of operations and location of product distribution, manufacturing and sale.
The FDA and various state regulatory authorities regulate the research, testing, manufacture, safety, labeling, storage, recordkeeping, premarket approval, marketing, advertising and promotion, import and export, and sales and distribution of pharmaceutical products in the U.S. Prior to marketing a pharmaceutical product, we must first receive FDA approval. In the U.S., the FDA regulates drugs under the Federal Food, Drug, and Cosmetic Act (“FDCA”) and implementing regulations. The process of obtaining regulatory approvals and compliance with appropriate federal, state, local, and foreign statutes and regulations requires the expenditure of substantial time and financial resources. Currently, the process required by the FDA before a drug product may be marketed in the U.S. generally involves the following:
Completion of preclinical laboratory tests, animal studies and formulation studies according to current Good Laboratory Practices regulations;
Submission to the FDA of an investigational new drug application (“IND”) which must become effective before human clinical trials may begin, including review and approval by any institutional review board (“IRB”), serving any of the institutions participating in the clinical trials;
Performance of adequate and well-controlled human clinical trials according to current Good Clinical Practices and other requirements, to establish the safety and efficacy of the proposed drug product for its intended use;
Submission to the FDA of an NDA for a new drug;
Satisfactory completion of an FDA inspection of the manufacturing facility or facilities at which the drug product is produced to assess compliance with current Good Manufacturing Practices (“cGMPs”) regulations; and
FDA review and approval of the NDA.
The testing and approval process requires substantial time, effort, and financial resources, and we cannot be certain that any approvals for our products in development will be granted on a timely basis, if at all. Once a pharmaceutical product is identified for development, it enters the preclinical testing stage. Preclinical tests include laboratory evaluations of product chemistry, toxicity, formulation, and stability, as well as animal studies to assess its potential safety and efficacy. This testing culminates in the submission of the IND to the FDA.
Once the IND becomes effective, including review and approval by any IRB serving any of the institutions participating in the clinical trial, the clinical trial program may begin. Each new clinical trial protocol must be submitted to the FDA before the trial may begin. The person, entity or organization taking responsibility for the trial is referred to as the clinical trial sponsor. Human clinical trials are typically conducted in three sequential phases that may overlap or be combined:
Phase 1. The product is initially introduced into healthy human subjects and tested for safety, dosage tolerance, absorption, metabolism, distribution and excretion. In the case of some products for severe or life-threatening diseases, especially when the product may be too inherently toxic to ethically administer to healthy volunteers, the initial human testing is often conducted in patients with those diseases.
Phase 2. Involves trials in a limited patient population to identify possible adverse effects and safety risks, to evaluate preliminarily the efficacy of the product for specific targeted diseases and to determine dosage tolerance and optimal dosage and schedule.
Phase 3. Clinical trials are undertaken to further evaluate dosage, clinical efficacy and safety in an expanded patient population at geographically dispersed clinical trial sites. These trials are intended to collect sufficient safety and efficacy data to support the NDA for FDA approval.
Progress reports detailing the results of the clinical trials must be submitted at least annually to the FDA and safety reports must be submitted to the FDA and the investigators for serious and unexpected adverse events. Submissions must also be made to inform the FDA of certain changes to the clinical trial protocol. Federal law also requires the sponsor to register the trials on public databases when they are initiated, and to disclose the results of the trials on public databases upon completion. Phase 1, Phase 2 and Phase 3 clinical trials may not be completed successfully within any specified period, if at all. The FDA or the clinical trial sponsor may suspend or terminate a clinical trial at any time on various grounds, including a finding that the research subjects or patients are being
19

exposed to an unacceptable health risk. Similarly, any IRB serving any of the institutions participating in the clinical trial can suspend or terminate approval of a clinical trial at an institution if the clinical trial is not being conducted in accordance with the IRB’s requirements or if the product has been associated with unexpected serious harm to patients. Failure to register a clinical trial or disclose study results within the required time periods could result in penalties, including civil monetary penalties.
Concurrent with clinical trials, companies usually complete additional animal studies and must also develop additional information about the chemistry and physical characteristics of the product and finalize a process for manufacturing the product in commercial quantities in accordance with cGMP requirements. The manufacturing process must be capable of consistently producing quality batches of the product and, among other things, the manufacturer must develop methods for testing the identity, strength, quality and purity of the final product. Additionally, appropriate packaging must be selected and tested and stability studies must be conducted to demonstrate that the product does not undergo unacceptable deterioration over its shelf life.
The results of product development, preclinical studies and clinical trials, along with descriptions of the manufacturing process, analytical tests conducted on the drug product, proposed labeling, and other relevant information, are submitted to the FDA as part of an NDA for a new drug, requesting approval to market the product. The submission of an NDA is subject to the payment of a substantial user fee. A waiver of that fee may be obtained under certain limited circumstances. The approval process is lengthy and difficult, and the FDA may refuse to approve an NDA if the applicable regulatory criteria are not satisfied. The FDA has substantial discretion in the product approval process, and it is impossible to predict whether and when the FDA will grant marketing approval. The FDA may on occasion require the sponsor of an NDA to conduct additional clinical trials or to provide other scientific or technical information about the product, and these additional requirements may lead to unanticipated delay or expense. Even if such data and information are submitted, the FDA may ultimately decide that the NDA does not satisfy the criteria for approval. Data obtained from clinical trials are not always conclusive, and the FDA may interpret data differently than we interpret the same data.
If a product receives regulatory approval, the approval may be significantly limited to specific diseases and dosages or the indications for use may otherwise be limited, which could restrict the commercial value of the product. Further, the FDA may require that certain contraindications, warnings or precautions be included in the product labeling. In addition, the FDA may require Phase 4 testing which involves clinical trials designed to further assess a drug product’s safety and effectiveness after NDA approval. The FDA also may impose one or more Risk Evaluation and Mitigation Strategies (“REMS”) to ensure that the benefits of a product outweigh its risks. A REMS could add training requirements for healthcare professionals, safety communications efforts and limits on channels of distribution, among other things. The sponsor would be required to evaluate and monitor the various REMS activities and adjust them if need be. Whether a REMS would be imposed on any of our products and any resulting financial impact is uncertain at this time.
Under the Orphan Drug Act, the FDA may designate a product as an Orphan Drug if it is a drug intended to treat a rare disease or condition, which is generally defined as a patient population of fewer than 200,000 individuals annually in the United States, or a patient population greater than 200,000 in the United States where there is no reasonable expectation that the cost of developing the drug will be recovered from sales in the United States.
In the United States, Orphan Drug designation entitles a party to financial incentives such as opportunities for grant funding towards clinical trial costs, tax advantages and user-fee waivers. In addition, if a product that has Orphan Drug designation subsequently receives the first FDA approval for the disease for which it has such designation, the product is entitled to Orphan Drug exclusivity, which means the FDA may not approve any other application to market the same drug for the same indication for a period of seven years, except in limited circumstances, such as a showing of clinical superiority over the product with orphan exclusivity or where the manufacturer is unable to assure sufficient product quantity.
Any drug products for which we receive FDA approvals are subject to continuing regulation by the FDA, including, among other things, record-keeping requirements, reporting of adverse experiences with the product, providing the FDA with updated safety and efficacy information, product sampling and distribution requirements, complying with certain electronic records and signature requirements, and complying with FDA promotion and advertising requirements. The FDA strictly regulates labeling, advertising, promotion and other types of information on drug products that are placed on the market. Drugs may be promoted only for the approved indications and consistent with the provisions of the approved label and promotional claims must be appropriately balanced with important safety information and otherwise be adequately substantiated. Further, manufacturers of drugs must continue to comply with cGMP requirements, which are extensive and require considerable time, resources and ongoing investment to ensure compliance. In addition, changes to the manufacturing process generally require prior FDA approval before being implemented, and other types of changes to the approved product, such as adding new indications and additional labeling claims, are also subject to further FDA review and approval.

Drug product manufacturers and other entities involved in the manufacturing and distribution of approved drugs products are required to register their establishments with the FDA and certain state agencies, and are subject to periodic unannounced inspections by the FDA and certain other agencies for compliance with cGMP and other laws. The cGMP requirements apply to all stages of the manufacturing process, including the production, processing, sterilization, packaging, labeling, storage and shipment of the drug product. Manufacturers must establish validated systems to ensure that products meet specifications and regulatory standards, and test each product batch or lot prior to its release. In addition, manufacturers of commercial PET products such as PYLARIFY, including radiopharmacies, hospitals and academic medical centers, are required to submit either an NDA or ANDA in order to produce PET drugs for clinical use, or produce the drugs under an IND.
The FDA also regulates the preclinical and clinical testing, design, manufacture, safety, efficacy, labeling, storage, record keeping, sales and distribution, post-market adverse event reporting, import/export and advertising and promotion of any medical devices that we distribute pursuant to the FDCA and FDA’s implementing regulations. The Federal Trade Commission shares jurisdiction with the FDA over the promotion and advertising of certain medical devices. The FDA can also impose restrictions on the sale, distribution or use of medical devices at the time of their clearance or approval, or subsequent to marketing. Currently, medical devices comprise only a small portion of our revenues.
The FDA may withdraw marketing authorization for a product if compliance with regulatory standards is not maintained or if problems occur after the product reaches the market. Later discovery of previously-unknown problems with a product may result in restrictions on the product or even complete withdrawal of the product from the market. Further, the failure to maintain compliance with regulatory requirements may result in administrative or judicial actions, such as fines, civil monetary penalties, warning letters, holds on clinical trials, product recalls or seizures, product detention or refusal to permit the import or export of products, refusal to approve pending applications or supplements, restrictions on marketing or manufacturing, injunctions, or civil or criminal penalties.
Regulations are subject to change as a result of legislative, administrative or judicial action, which may also increase our costs or reduce sales or otherwise adversely impact our products. For example, on April 16, 2021 in the case Genus Medical Technologies LLC v. Food and Drug Administration, the U.S. Court of Appeals for the D.C. Circuit held that a product (other than a combination product) that meets the definitions of both “drug” and “device” under the FDCA must be regulated as a device. On August 9, 2021, the FDA announced that, as part of its implementation of this court decision, the FDA intended to regulate products that meet both the device and drug definition as devices, except where Congress intended a different classification. The FDA further indicated that it intended to bring previously classified products into line with the court decision and would reexamine whether individual imaging agents meet the device definition, which raised uncertainty as to how our some of our products would be regulated. Congress subsequently resolved this issue when it passed the Consolidated Appropriations Act of 2023, which amended the FDCA by adding a provision that deemed any contrast agent or radioactive drug to be a drug.
Because our operations include the manufacture and distribution of medical radioisotopes and other medical products, we are subject to regulation by the NRC and the departments of health of each state in which we operate and the applicable state boards of pharmacy. In addition, the FDA is also involved in the regulation of cyclotron facilities where PET products are produced in compliance with cGMP requirements and U.S. Pharmacopeia requirements for PET drug compounding.
Drug laws also are in effect in many of the non-U.S. markets in which we or our partners conduct business. These laws range from comprehensive drug approval requirements to requests for product data or certifications. In addition, inspection of and controls over manufacturing, as well as monitoring of adverse events, are components of most of these regulatory systems. Most of our business is subject to varying degrees of governmental regulation in the countries in which we or our partners operate, and the general trend is toward increasingly stringent regulation. The exercise of broad regulatory powers by the FDA continues to result in increases in the amount of testing and documentation required for approval or clearance of new drugs and devices, all of which add to the expense of product introduction. Similar trends also are evident in major non-U.S. markets, including Canada, the European Union, Australia and Japan.
To assess and facilitate compliance with applicable FDA, NRC and other state, federal and foreign regulatory requirements, we regularly review our quality systems to assess their effectiveness and identify areas for improvement. As part of our quality review, we perform assessments of our suppliers of the raw materials that are incorporated into products and conduct quality management reviews designed to inform management of key issues that may affect the quality of our products. From time to time, we may determine that products we manufactured or marketed do not meet our specifications, published standards, such as those issued by the International Standards Organization, or regulatory requirements. When a quality or regulatory issue is identified, we investigate the issue and take appropriate corrective action, such as withdrawal of the product from the market, correction of the product at the customer location, notice to the customer of revised labeling and other actions.

Hatch-Waxman Act
The Hatch-Waxman Act added two pathways for FDA drug approval. First, the Hatch-Waxman Act permits the FDA to approve ANDAs for generic versions of drugs if the ANDA applicant demonstrates, among other things, that its product is bioequivalent to the innovator product and provides relevant chemistry, manufacturing and product data. See “Item 1. Business - Patents.” Second, the Hatch-Waxman Act created what is known as a Section 505(b)(2) NDA, which requires the same information as a full NDA (known as a Section 505(b)(1) NDA), including full reports of clinical and preclinical studies but allows some of the information from the reports required for marketing approval to come from studies which the applicant does not own or have a legal right of reference. A Section 505(b)(2) NDA permits a manufacturer to obtain marketing approval for a drug without needing to conduct or obtain a right of reference for all of the required studies. The Hatch-Waxman Act also provides for: (1) restoration of a portion of a product’s patent term that was lost during clinical development and application review by the FDA; and (2) statutory protection, known as exclusivity, against the FDA’s acceptance or approval of certain competitor applications.
Under U.S. law, patent term extension can compensate for time lost during product development and the regulatory review process by returning up to five years of patent life for a patent that covers a new product or its use. This period is generally one-half the time between the effective date of an IND and the submission date of an NDA, plus the time between the submission date of an NDA and the approval of that application. Patent term extensions, however, are subject to a maximum extension of five years, and the patent term extension cannot extend the remaining term of a patent beyond a total of 14 years. The application for patent term extension is subject to approval by the U.S. Patent and Trademark Office in conjunction with the FDA.
The Hatch-Waxman Act also provides for a period of statutory protection for new drugs that receive NDA approval from the FDA. If the FDA approves a Section 505(b)(1) NDA for a new drug that is a new chemical entity, meaning that the FDA has not previously approved any other new drug containing the same active moiety, then the Hatch-Waxman Act prohibits the submission or approval of an ANDA or a Section 505(b)(2) NDA for a period of five years from the date of approval of the NDA, except that the FDA may accept an application for review after four years under certain circumstances, specifically a patent challenge for one or more patents listed by the NDA holder in FDA’s publication, Approved Drug Products with Therapeutic Equivalence Evaluations (the “Orange Book”), submitted in a “Paragraph IV” Certification. The Hatch-Waxman Act will not prevent the filing or approval of a full NDA, as opposed to an ANDA or Section 505(b)(2) NDA, for any drug, but the competitor would be required to conduct its own clinical trials, and any use of the drug for which marketing approval is sought could not violate another NDA holder’s patent claims. The Hatch-Waxman Act provides for a three-year period of exclusivity for an NDA for a new drug containing an active moiety that was previously approved by the FDA, but also includes new clinical data (other than bioavailability and bioequivalence studies) to support an innovation over the previously-approved drug and those studies were conducted or sponsored by the applicant and were essential to approval of the application. This three-year exclusivity period does not prohibit the FDA from accepting an application from a third party for a drug with that same innovation, but it does prohibit the FDA from approving that application for the three-year period. The three-year exclusivity does not prohibit the FDA, with limited exceptions, from approving generic drugs containing the same active ingredient but without the new innovation.
Reimbursement
The successful commercialization of our products is also subject to the availability of appropriate third-party coding, coverage and payment for our customers. Third-party payors in the U.S. include private payors, including managed care providers, and State and Federal healthcare programs, such as Medicare and Medicaid. The process for determining whether a payor will provide coverage for a product may be separate from the process for setting the price or reimbursement rate that the payor will pay for the product. Coverage of a product does not ensure there will be an appropriate reimbursement amount for such product and the process to ensure appropriate reimbursement is outside our control. For private payors, coverage and reimbursement of our products vary from private payor to private payor. Many private payors, such as managed care providers, manage access to products, and may use medical policies (which may include specific coverage requirements such as prior authorization, re-authorization and achieving performance metrics under value-based contracts) to control utilization. Exclusion from or restriction in coverage can reduce product use. For government payors, we participate, as required, in the Medicaid drug rebate program, the Federal Supply Schedule (FSS) and the Public Health Service Act 340B program, which each require discounts for participation and may be subject to change. For Medicare, reimbursement to customers for our products is generally established through the rulemaking process or in discussion with Medicare Administrative Contractors (MACs). We have ongoing conversations with third-party payors to advocate for appropriate coding, coverage and payment for our portfolio of products.
Medicare Outpatient TPT Status
Part B of the Medicare program generally reimburses medical services and supplies, including drugs, provided to beneficiaries by physicians and other qualified healthcare professionals. Generally, drugs furnished “incident to” a physician’s service in the hospital outpatient setting of care are reimbursed at Average Sales Price (“ASP”) plus a certain additional percent, unless the product is treated as a “supply” in the performance of the procedure and “packaged” and paid as part of bundled payment for the procedure.
22

Table of Contents

Novel drugs, however, may apply for TPT Status in which case they are provided a separate payment at ASP plus a certain additional percent for two to three years, regardless of whether they would ordinarily be packaged.
PYLARIFY has received TPT Status effective January 1, 2022 through December 31, 2024, thereby providing separate reimbursement to customers using PYLARIFY in the hospital outpatient setting during this specified period. The reimbursement rate for PYLARIFY was initially based on the wholesale acquisition cost (WAC) plus three percent until ASP could be established. In 2023, CMS established an ASP for PYLARIFY and reimbursed at a rate equal to ASP plus an add-on percentage that varied throughout the year.
PYLARIFY has been assigned Healthcare Common Procedure Coding System code A9595 (piflufolastat F 18, diagnostic, 1 millicurie) for identification in claims and can be used by both public and private payors. Under existing Medicare policy for the hospital outpatient setting of care, non-pass-through diagnostic radiopharmaceuticals are not separately paid and are instead packaged into payment for the underlying procedure. Therapeutic radiopharmaceuticals are paid separately by Medicare OPPS regardless of TPT Status. We plan to continue our advocacy efforts with CMS and private insurers so that PYLARIFY customers will have appropriate and adequate reimbursement following the expiration of TPT Status. We are also supporting trade associations in their efforts to have Congress pass the Facilitating Innovative Nuclear Diagnostics (FIND) Act, which would allow for separate payment for certain diagnostic radiopharmaceuticals, including PYLARIFY, similar to the way Medicare OPPS currently pays for other drugs, biologics, and therapeutic radiopharmaceuticals instead of under the current TPT structure of a separate payment that is limited to three years.
Healthcare Reform and Other Laws Affecting Payment
We operate in a highly regulated industry. The U.S. and state governments continue to propose and pass legislation that may affect the availability and cost of healthcare. For example, the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act (collectively, the “Healthcare Reform Act”), substantially changes the way in which healthcare is financed by both governmental and private insurers and has a significant impact on the pharmaceutical industry. The Healthcare Reform Act contains a number of provisions that affect coverage, reimbursement and/or delivery of drug products and the medical imaging procedures in which our drug products are used. Key provisions that currently affect our business include the following:
increasing the presumed utilization rate for imaging equipment costing $1.0 million or more in the physician office and free-standing imaging facility setting which reduces the Medicare per procedure medical imaging reimbursement; which rate was further increased by subsequent legislation effective January 1, 2014;
increasing drug rebates paid to state Medicaid programs under the Medicaid Drug Rebate Program for brand name prescription drugs and extending those rebates to Medicaid managed care organizations;
expanding access to the 340B program by allowing additional covered entities to participate in the program; and
imposing a non-deductible annual fee on pharmaceutical manufacturers or importers who sell brand name prescription drugs to specified federal government programs.
The Healthcare Reform Act also amended the federal self-referral laws, requiring referring physicians to inform patients under certain circumstances that the patients may obtain services, including PET, CT, MRI and certain other diagnostic imaging services, from a provider other than that physician, another physician in his or her group practice, or another individual under direct supervision of the physician or another physician in the group practice. The referring physician must provide each patient with a written list of other suppliers who furnish those services in the area in which the patient resides. These requirements could have the effect of shifting where certain diagnostic medical imaging procedures are performed.
The Healthcare Reform Act has been subject to political and judicial challenges, but it has generally withstood such challenges, and the main provisions of the Healthcare Reform Act remain in effect. More recently, Congress enacted the Inflation Reduction Act of 2022 (the “IRA”) which significantly impacts the pharmaceutical industry. Among other provisions, the IRA authorizes Medicare to negotiate pricing for the highest Medicare-spend drugs, as determined by their Medicare Part B and D spend, that have been on the market for an extended period of time without market competition. Although the IRA provides for a limited number of categorical exclusions from Medicare negotiation, radiopharmaceuticals are not among those categorical exclusions. CMS plans to begin implementing the first year of Medicare negotiation, which will be restricted to Part D drugs, starting in calendar years 2026 and 2027. We are currently focused on drugs that are covered under Part B, therefore we do not expect the Part D benefit redesign to have an impact on our portfolio. Part B drugs will be considered for Medicare negotiation beginning in calendar year 2028, and CMS will begin the process of identifying Part B drugs for negotiation as early as calendar year 2026. We are monitoring the implementation of the IRA to determine what impact, if any, this would have on our current products and product candidates in development.
The IRA also introduces rebate obligations for manufacturers of Part B and D drugs that take price increases which exceed the rate of inflation, similar to the longstanding Medicaid inflation rebates. Under these new Medicare inflation rebates, each Part B and D

single-source drug/biological and biosimilar will have an “inflation adjusted” payment amount calculated by CMS. If the manufacturer’s price increases for the relevant product exceeds the inflation adjusted payment amount, as trended forward by the rate of inflation, the manufacturer will be required to reimburse Medicare the difference between what Medicare paid for the product and what it would have paid based on the inflation adjusted payment amount.
Recent state legislative efforts seek to address drug costs and generally have focused on increasing transparency around drug costs or limiting drug prices. Some of those efforts have been subject to legal challenge.
General legislative cost control measures may also affect reimbursement for our products or services provided with our products. The Budget Control Act, as amended by the Bipartisan Budget Act of 2019, resulted in the imposition of 2% reductions in Medicare (but not Medicaid) payments to providers beginning in 2013 and will remain in effect through fiscal year 2030 unless additional Congressional action is taken. The imposition of the 2% payment adjustment had been suspended through March 31, 2022 and went into effect as of April 1, 2022. Any significant spending reductions affecting Medicare, Medicaid or other publicly funded or subsidized health programs that may be implemented and/or any significant taxes or fees that may be imposed on us could have an adverse impact on our business results of operations, financial condition and cash flows.
Healthcare Fraud and Abuse Laws
We are subject to various federal, state and local laws targeting fraud and abuse in the healthcare industry, including anti-kickback and false claims laws. Violations of fraud and abuse laws may be punishable by criminal or civil sanctions, including fines and civil monetary penalties, and/or exclusion from federal health care programs (including Medicare and Medicaid). Federal and state authorities are paying increased attention to enforcement of these laws within the pharmaceutical industry, and private individuals have been active in alleging violations of the laws and bringing suits on behalf of the government under the federal False Claims Act (“FCA”). Violations of international fraud and abuse laws could result in similar penalties, including exclusion from participation in health programs outside the U.S. If we were subject to allegations concerning, or were convicted of violating, these laws, our business could be harmed.
The federal Anti-Kickback Statute generally prohibits, among other things, a pharmaceutical manufacturer from directly or indirectly soliciting, offering, receiving, or paying any remuneration in cash or in kind where one purpose is either to induce the referral of an individual for, or the purchase or prescription of a particular drug that is payable by a federal health care program, including Medicare or Medicaid. The Healthcare Reform Act clarifies the intent requirements of the federal Anti-Kickback Statute, providing that a person or entity does not need to have actual knowledge of the statute or a specific intent to violate the statute. Violations of the federal Anti-Kickback Statute can result in exclusion from Medicare, Medicaid or other governmental programs as well as civil and criminal fines and penalties of up to $104,330 per violation and three times the amount of the unlawful remuneration. In addition, the Healthcare Reform Act revised the FCA to provide that a claim arising from a violation of the Federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the FCA. The majority of states also have anti-kickback, false claims, and similar fraud and abuse laws and although the specific provisions of these laws vary, their scope is generally broad, and there may not be regulations, guidance or court decisions that apply the laws to particular industry practices. There is, therefore, a possibility that our practices might be challenged under the anti-kickback statutes or similar laws.
Federal and state false claims laws generally prohibit anyone from knowingly and willfully, among other activities, presenting, or causing to be presented for payment to third party payors (including Medicare and Medicaid) claims for drugs or services that are false or fraudulent (which may include claims for services not provided as claimed or claims for medically unnecessary services). As discussed, a claim arising from a violation of the federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the FCA. False or fraudulent claims for purposes of the FCA carry fines and civil penalties for violations ranging from $11,665 to $23,331 for each false claim, plus up to three times the amount of damages sustained by the federal government and, most critically, may provide the basis for exclusion from federally funded healthcare programs. There is also a criminal FCA statute by which individuals or entities that submit false claims can face criminal penalties. In addition, under the federal Civil Monetary Penalty Law, the Department of Health and Human Services Office of Inspector General has the authority to exclude from participation in federal health care programs or to impose civil penalties against any person who, among other things, knowingly presents, or causes to be presented, certain false or otherwise improper claims. Our activities relating to the sale and marketing of our products may be subject to scrutiny under these laws.

Laws and regulations have also been enacted by the U.S. federal government and various states, as well as by countries outside of the U.S., to regulate the sales and marketing practices of certain entities including pharmaceutical and device manufacturers. The laws and regulations generally limit financial interactions between manufacturers and health care providers; require pharmaceutical companies to comply with the pharmaceutical industry’s voluntary compliance guidelines and the relevant compliance guidance promulgated by the U.S. federal government; and/or require disclosure by pharmaceutical and device manufacturers to the government and/or public of financial interactions or other financial relationships with health care providers and other entities such as teaching hospitals (so-called “sunshine laws”). The Healthcare Reform Act requires manufacturers to submit information to the FDA on the identity and quantity of drug samples requested and distributed by a manufacturer during each year. Many of these laws and regulations contain ambiguous requirements or require administrative guidance for implementation. The laws and regulations include requirements that can be unclear in their scope, nature, and required implementation by regulated entities. If we fail to comply with such laws and regulations, we could be subject to penalties and administrative actions under such laws and regulations.
Data Privacy, Security and Breach Notification
We are subject to data protection laws and regulations that set forth data privacy, security, and breach notification requirements. The legislative and regulatory landscape for data protection continues to evolve, and in recent years there has been an increasing focus on data protection and other data privacy and security issues. In the United States, numerous federal and state laws and regulations, including state data breach notification laws, state health information privacy laws and federal and state consumer protection laws govern the collection, use, disclosure and protection of health-related and other personal information. In addition to establishing restrictions on how personal information may be collected, used, and disclosed, these laws and regulations provide various rights to data subjects with respect to their personal information and establish requirements for how personal information must be secured. In addition, every state in the United States now has a data breach notification law that requires regulated entities to report certain security breaches to affected data subjects, regulators, or other entities. Failure to comply with data protection laws and regulations could result in government enforcement actions (which could include civil or criminal penalties and requirements to take corrective actions), private litigation (which may result in the award of damages against us), and/or adverse publicity, and could negatively affect our operating results, business, and reputation. In addition, we may obtain health information from third parties (e.g., healthcare providers who prescribe our products) that are themselves subject to privacy, security, and breach notification requirements under the Health Insurance Portability and Accountability Act of 1996, as amended by the Health Information Technology for Economic and Clinical Health Act (collectively, “HIPAA”). While we believe that we are neither a “covered entity” nor “business associate” subject directly to regulation under HIPAA, HIPAA’s criminal provisions can apply to entities other than “covered entities” or “business associates” in certain circumstances. Accordingly, we could be subject to criminal penalties if we knowingly obtain or disclose individually identifiable health information from a HIPAA-covered entity in a manner that is not authorized or permitted.
In addition, a growing number of jurisdictions outside of the United States have enacted robust data protection laws. Certain of these laws have extraterritorial application. For example, the processing of personal data in the European Union is governed by the provisions of the General Data Protection Regulation, or GDPR, which came into effect on May 25, 2018. The GDPR applies to an entity established in the EU and extraterritorially to an entity outside of the EU that offers goods or services to, or monitors the behavior of, individuals located in the EU. Certain “special categories” of personal data, including data concerning health, are subject to enhanced protections under the GDPR. This regulation imposes several requirements on the controllers and processors of personal data, including the obligation to comply with various rights that individuals have with respect to their personal data and restrictions on the processing of personal data, and to provide notice of data processing obligations to the competent national data protection authorities. The GDPR also imposes strict rules on the transfer of personal data out of the European Union to the United States. Failure to comply with the requirements of the GDPR and the related national data protection laws of the European Union Member States may result in significant fines and other administrative penalties.
In the United States, several state legislatures are considering enacting new data privacy legislation. One example of such legislation that has already been passed is the California Consumer Privacy Act (“CCPA”), which took effect on January 1, 2020 and imposes many requirements on certain for-profit businesses that process the personal information of California residents. Many of the CCPA’s requirements are similar to those found in the GDPR, including requiring businesses to provide notice to data subjects regarding the information collected about them and how such information is used and shared, and providing data subjects various rights, such as the right to request access to their personal information and, in certain cases, request the erasure of such personal information. The CCPA also affords California residents the right to opt-out of the “sale” of their personal information. In addition, the CCPA requires regulated businesses to implement reasonable security procedures and practices to protect personal information. The CCPA contains significant penalties for companies that violate its requirements. It also provides California residents a private right of action, including the ability to seek statutory damages, in the event of a breach involving their personal information resulting from a business’s failure to implement and maintain reasonable security procedures and practices. Compliance with the CCPA, and similar laws implemented in other states, is a rigorous and time-intensive process that may increase the cost of doing business or require companies to change their business practices to ensure full compliance.

On November 3, 2020, California passed the California Privacy Rights Act (“CPRA”) through a ballot initiative. The CPRA amends the CCPA and expands its protections for personal information, including by establishing a new California Privacy Protection Agency to enforce the CPRA and by providing California consumers various rights such as the right to restrict the processing of their “sensitive personal information.” The CPRA’s amendments to the CCPA took effect on January 1, 2023, and generally apply to personal information collected by regulated businesses on or after January 1, 2022.
Antitrust and Competition Laws
The federal government and most states have enacted antitrust laws that prohibit specific types of anti-competitive conduct, including price fixing, wage fixing, concerted refusals to deal, price discrimination and tying arrangements, as well as monopolization and acquisitions of competitors that have, or may have, a substantial adverse effect on competition. Violations of federal or state antitrust laws can result in various sanctions, including criminal and civil penalties. We believe we are in compliance with such federal and state laws, but courts or regulatory authorities may reach a determination in the future that could adversely affect our business, results of operations, financial condition and cash flows. In addition, we are subject to similar antitrust and anti-competition laws in foreign countries. We believe we are in compliance with such laws, however, any violation could create a substantial liability for us and also cause a loss of reputation in both foreign and domestic markets. 
Laws Relating to Foreign Trade
We are subject to various federal and foreign laws that govern our international business practices with respect to payments to government officials. Those laws include the Foreign Corrupt Practices Act (“FCPA”) which prohibits U.S. companies and their representatives from paying, offering to pay, promising, or authorizing the payment of anything of value to any foreign government official, government staff member, political party, or political candidate for the purpose of obtaining or retaining business or to otherwise obtain favorable treatment or influence a person working in an official capacity. In many countries, the healthcare professionals we regularly interact with may meet the FCPA’s definition of a foreign government official. The FCPA also requires public companies to make and keep books and records that accurately and fairly reflect their transactions and to devise and maintain an adequate system of internal accounting controls.
Those laws also include the U.K. Bribery Act (“Bribery Act”) which proscribes giving and receiving bribes in the public and private sectors, bribing a foreign public official, and failing to have adequate procedures to prevent employees and other agents from giving bribes. U.S. companies that conduct business in the United Kingdom generally will be subject to the Bribery Act. Penalties under the Bribery Act include potentially unlimited fines for companies and criminal sanctions for corporate officers under certain circumstances.
Our policies mandate compliance with these anti-bribery laws. Our operations reach many parts of the world that have experienced governmental corruption to some degree, and in certain circumstances strict compliance with anti-bribery laws may conflict with local customs and practices. Despite our training and compliance programs, our internal control policies and procedures may not always protect us from reckless or criminal acts committed by our employees or agents.
We are also subject to trade control regulations and trade sanctions laws that restrict the movement of certain goods, currency, products, materials, services and technology to, and certain operations in, various countries or with certain persons. Our ability to transfer people and products among certain countries may be subjected to these laws and regulations.
Health and Safety Laws
We are also subject to various federal, state and local laws, regulations and recommendations, both in the U.S. and abroad, relating to safe working conditions, laboratory and manufacturing practices and the use, transportation and disposal of hazardous or potentially hazardous substances.
See Part I, Item 1A. “Risk Factors” for information regarding certain risks related to reimbursement and regulation.
Environmental Matters
We are subject to various federal, state and local laws and regulations relating to the protection of the environment, human health and safety in the U.S. and in other jurisdictions in which we operate. Our operations, like those of other medical product companies, involve the transport, use, handling, storage, exposure to and disposal of materials and wastes regulated under environmental laws, including hazardous and radioactive materials and wastes. If we violate these laws and regulations, we could be fined, criminally charged or otherwise sanctioned by regulators. We believe that our operations currently comply in all material respects with applicable environmental laws and regulations.

Table of Contents

Certain environmental laws and regulations assess liability on current or previous owners or operators of real property for the cost of investigation, removal or remediation of hazardous materials or wastes at those formerly owned or operated properties or at third party properties at which they have disposed of hazardous materials or wastes. In addition to cleanup actions brought by governmental authorities, private parties could bring personal injury, property damage or other claims due to the presence of, or exposure to, hazardous materials or wastes. We currently are not party to any claims or any obligations to investigate or remediate any material contamination at any of our facilities, however, if we were found to be liable under one or more of these laws or regulations, it could create a substantial liability.
We are required to maintain a number of environmental permits and nuclear licenses for our North Billerica, Massachusetts campus, which includes our primary manufacturing, packaging and distribution facility. In particular, we must maintain a nuclear byproducts materials license issued by the Commonwealth of Massachusetts. This license requires that we provide financial assurance demonstrating our ability to cover the cost of decommissioning and decontaminating (“D&D”) the Billerica site at the end of its use as a nuclear facility. In addition, we have a radioactive production facility in Somerset, NJ where we must also maintain a number of environmental permits and nuclear licenses. We store low level radioactive waste at our facilities until the materials are below regulatory limits, as allowed by our licenses and permits. As of December 31, 2023, we currently estimate the D&D cost of all of our manufacturing sites to be approximately $25.1 million. As of December 31, 2023 and 2022, we have a liability of approximately $22.9 million and $22.5 million, respectively associated with our asset retirement obligations. We currently provide this financial assurance in the form of surety bonds.
We also actively monitor and seek to reduce our solid waste, energy and water usage, waste water discharge and greenhouse gas emissions. We generally contract with third parties for the disposal of wastes generated by our operations. In 2020, we developed a stormwater management operations and maintenance plan to minimize stormwater pollution from high impact activities. Improvements we made include (i) the regular inspection and cleaning of catch basins and piping to reduce sediment and debris wash out to adjacent wetlands; (ii) increasing street and parking lot cleaning to reduce pollutant run off; (iii) updating our snow removal plan at our North Billerica campus to reduce the impact to adjacent wetlands; and (iv) using salt brine as a pretreatment for winter storms to reduce the amount of salt use and run off.
With respect to sustainability, we track and monitor our energy use, water use, a limited scope of greenhouse gas emissions, and waste generation. We use an Energy Star Portfolio Manager to track energy and water use and have calculated scope 1 and 2 greenhouse gas emissions for our North Billerica Campus, with plans to expand these activities to other Lantheus properties. We will continue to compare our usage data against annual baselines, national medians, and similar buildings.
Environmental laws and regulations are complex, change frequently and have become more stringent over time. While we have budgeted for future capital and operating expenditures to maintain compliance with these laws and regulations, we cannot assure you that our costs of complying with current or future environmental protection, health and safety laws and regulations will not exceed our estimates or adversely affect our results of operations and financial condition. Further, we cannot assure you that we will not be subject to additional environmental claims for personal injury or cleanup in the future based on our past, present or future business activities. While it is not feasible to predict the future costs of ongoing environmental compliance, it is possible that there will be a need for future provisions for environmental costs that, in management’s opinion, are not likely to have a material effect on our financial condition, but could be material to the results of operations in any one accounting period.
See Part I, Item 1A. “Risk Factors” for information regarding certain risks associated with environmental matters.
Human Capital Management
As of December 31, 2023, we had 834 employees, of which 808 were located in the U.S. and 26 were located internationally. None of our employees are represented by a collective bargaining agreement, and we believe that our relationship with our employees is good.
Diversity, Inclusion, Ethics and Compliance
We believe that supporting our local community and instilling a diverse, inclusive, ethical and compliant culture makes us an employer of choice, allows us to maintain good standing with the regulatory authorities and our customers, and benefits our stockholders in the long run.
We have a female Chief Executive Officer who, effective March 1, 2024, will transition to Chair of the Board, over half of our Vice Presidents and above (including our senior management team, which we refer to as our “Expanded Executive Team”) are women, and approximately 50% of our employees are women. We continue to strive to improve our diversity and inclusion with a strategic emphasis beyond gender, and we require recruiters working with us to present diverse candidates. We also sponsor three Employee Resource Groups (“ERGs”), the Lantheus Diversity Connection ERG, the Women Leaders of Lantheus ERG, and the Professional Networking at Lantheus ERG.

We are committed to promoting a culture of ethics and compliance. Our Code of Conduct and Ethics reflects our commitment to corporate integrity and the underlying business practices and principles of behavior that support this commitment. Each year our employees complete mandatory training that includes anti-bribery/anti-corruption rules, insider trading prohibitions, confidentiality obligations, as well as specialized training in healthcare industry marketing practices. We have a formal Ethics and Compliance Committee that develops, implements and oversees our ethics and compliance programs. We also have a Supplier Code of Conduct, and we seek to do business with minority-owned, female-owned and other diverse businesses and organizations (including those owned or operated by veterans and disabled veterans) that appropriately reflect the communities in which we operate and the customer base we serve.
Compensation and Benefits
We seek to provide pay, benefits, and services that are competitive to market and create incentives to attract and retain employees. Our compensation package includes, among other things, market-competitive pay, cash bonuses, healthcare and defined contribution plan benefits, paid time off and family leave, and restricted stock and other equity grants to certain levels of employees. We are focused on pay equity and regularly assess pay among similar roles and responsibilities throughout our organization and in comparison to our peer group.
Communication and Engagement
We believe that our success depends on employees understanding how their work contributes to our overall strategy. To this end, we utilize a variety of channels to facilitate open and direct communication, including: (i) quarterly town hall meetings for our entire company; (ii) regular ongoing update communications, including through monthly newsletters and our recently launched intranet site; and (iii) an externally administered whistleblower hotline and website that is prominently advertised to our employees, and a whistleblower’s anonymity is protected, if so requested. We also established various employee recognition award programs to recognize and reward employees for specific outstanding accomplishments and to foster a positive employee relations climate.
Health, Wellness and Safety
We are committed to the health and safety of our employees, patients and other partners in the healthcare community. We work to promote an environment of awareness and shared responsibility for safety and regulatory compliance throughout the Company, in order to minimize risks of injury, exposure, or business impact.
Corporate History
Founded in 1956 as New England Nuclear Corporation, our medical imaging diagnostic business was purchased by E.I. du Pont de Nemours and Company (“DuPont”) in 1981. Bristol Myers Squibb (“BMS”) subsequently acquired our diagnostic medical imaging business as part of its acquisition of DuPont Pharmaceuticals in 2001. In January 2008, Avista Capital Partners, L.P., Avista Capital Partners (Offshore), L.P. and ACP-Lantern Co-Invest, LLC formed Lantheus Holdings and acquired our medical imaging business from BMS. On June 30, 2015, we completed an initial public offering of our common stock. We completed our acquisition of Progenics on June 19, 2020 (the “Progenics Acquisition”). We completed our acquisition of Cerveau Technologies, Inc. on February 6, 2023 (the “Cerveau Acquisition”). Our common stock is traded on the NASDAQ Global Market under the symbol “LNTH”.

Item 1A. Risk Factors
You should carefully consider the following risks. The risks and uncertainties described below are not the only ones we face. Additional risks and uncertainties that we are unaware of, or that we currently believe are not material, may also become important factors that adversely affect our business. These risks could materially affect our business, results of operations or financial condition, cause the trading price of our outstanding common stock to decline materially or cause our actual results to differ materially from those expected or those expressed in any forward-looking statements made by us or on our behalf. See “Cautionary Note Regarding Forward-Looking Statements” and the risks of our businesses described elsewhere in this Annual Report on Form 10‑K.
Risks Related to Our Portfolio of Commercial Products
Our ability to continue to grow PYLARIFY as a commercial product is dependent on (A) the ability of PMFs to manufacture PYLARIFY to meet product demand, (B) our ability to promote PYLARIFY to customers, (C) our ability to obtain and maintain adequate coding, coverage and payment for PYLARIFY, (D) our ability to maintain PYLARIFY as the leading PSMA PET imaging agent, including after the potential expiration of TPT Status at the end of 2024 and (E) our ability to clinically and commercially differentiate PYLARIFY from other products.
To manufacture PYLARIFY, we assembled and qualified a nationwide network of PMFs with radioisotope-producing cyclotrons that make F 18, which has a 110-minute half-life, so PYLARIFY is manufactured and distributed rapidly to end-users. Because each of the PMFs manufacturing these products is deemed by the FDA to be a separate manufacturing site, each has to be separately approved by the FDA. Although PYLARIFY is broadly available across the U.S., we continue to seek qualification for additional PMFs in 2024 and can give no assurance that the FDA will continue to approve PMFs in accordance with our planned roll-out schedule. If FDA approval of manufacturing sites is delayed or withdrawn, our business, results of operations, financial condition and cash flows could be adversely affected.
PYLARIFY is sold in the U.S. to hospitals, independent imaging centers and government facilities and sales are generated through an internal PYLARIFY sales team, as well as a sales team at some of our PMF partners. We generally do not use group purchasing arrangements to sell PYLARIFY and require each customer to enter into a contract directly with us or our PMFs. Our ability to continue to successfully grow PYLARIFY depends, in part, on our ability to continue to enter into arrangements directly with the hospitals, independent imaging centers and government facilities that we serve. Any delay or inability to enter into these arrangements could have an adverse impact on our business, results of operations, financial condition and cash flows.
Obtaining adequate coding, coverage and payment for PYLARIFY is critical, including not only coverage from Medicare, Medicaid and other government payors, as well as private payors, but also appropriate payment levels to adequately cover our customers’ costs of using PYLARIFY in PET/CT imaging procedures. We received notification that our HCPCS code, which enables streamlined billing, went into effect as of January 1, 2022. In addition, effective January 1, 2022, CMS granted TPT Status for PYLARIFY, enabling traditional Medicare to provide an incremental payment for PET/CT scans performed with PYLARIFY in the hospital outpatient setting. TPT Status for PYLARIFY is expected to expire on December 31, 2024. After TPT Status expires, under current Medicare rules, PYLARIFY would not be separately reimbursed in the hospital outpatient setting but rather would be bundled into the facility payment a hospital receives for a PET/CT imaging procedure, and the facility payment may not always adequately cover the total cost of the procedure. We can give no assurance that any CMS reimbursement in the hospital outpatient setting that follows the expiration of TPT Status will be adequate to cover the cost of a PYLARIFY PET/CT imaging procedure. In addition, if other government payors or private payors do not provide adequate reimbursement for the use of PYLARIFY, our business, results of operations, financial condition and cash flows could be adversely affected. We plan to continue our advocacy efforts with CMS and private insurers so that PYLARIFY customers will have appropriate and adequate reimbursement following the expiration of TPT Status and we are also supporting trade associations in their efforts to have Congress pass the Facilitating Innovative Nuclear Diagnostics (FIND) Act, which would allow for separate payment for certain diagnostic radiopharmaceuticals, including PYLARIFY, similar to the way Medicare OPPS currently pays for other drugs, biologics, and therapeutic radiopharmaceuticals instead of under the current TPT structure of a separate payment that is limited to three years, however, we can give no assurances that we will be successful in those efforts or that the availability of TPT Status for other diagnostic radiopharmaceuticals will not impact clinical decision making regarding which product to use, which could have an adverse effect on our business, results of operations, financial condition and cash flows.
The successful growth of PYLARIFY is also dependent on our ability to clinically and commercially differentiate PYLARIFY from other products on the market and to maintain PYLARIFY as the leading PSMA PET imaging agent in a competitive environment in which other PSMA PET imaging agents have been approved. PYLARIFY currently competes with two commercially available Ga-68-based PSMA PET imaging agents from Telix Pharmaceuticals Limited and Novartis AG and an F 18 PSMA PET imaging agent from Blue Earth, as well as other non-PSMA PET imaging agents. To the extent we lose market share to existing or future competitors (including during any period of time in which our TPT Status has expired but TPT Status for a later-approved competitive products still exists), such loss of market share could have an adverse impact on our business, results of operations, financial condition and cash flows. Continued growth and revenue contribution from PYLARIFY will also depend on our ability to differentiate

PYLARIFY in light of the potential loss of TPT Status, including through flexible and dependable access to PYLARIFY nationally, a best in class customer experience and through long-term strategic contracts.
Our success in growing PYLARIFY also depends, in part, on our successfully establishing the use of PYLARIFY for approved indications and potentially for additional indications, including for patient selection for PSMA-targeted therapeutics. For example, we believe the approval of PLUVICTO for the treatment of adult patients with PSMA-positive mCRPC who have already been treated with other anticancer treatments (androgen receptor pathway inhibition and taxane-based chemotherapy) created a new addressable market for the use of PSMA PET imaging in patient selection for PSMA-targeted therapy. However, the prescribing information for PLUVICTO specifies that a PSMA-11 based PSMA PET imaging agent be used for patient selection, and PYLARIFY is not a PSMA-11 based imaging agent. While we note that FDA-approved labels for F 18-based and PSMA-11 based PSMA PET imaging agents have generally been treated as a class of drugs, including by the National Comprehensive Cancer Center in its guidelines and the Society for Nuclear Medicine and Molecular Imaging in its appropriate use criteria, we can give no assurances that PLUVICTO prescribing information will be expanded to incorporate F 18-based PSMA PET imaging agents like PYLARIFY, or how clinical practice may evolve. To the extent we are unsuccessful in establishing the use of PYLARIFY for approved or new indications, such lack of success could have an adverse impact on our business, results of operations, financial condition and cash flows.
The near-term growth of our business is also dependent on our ability to continue to grow the appropriate use of DEFINITY in suboptimal echocardiograms in the face of competition from other existing echocardiography agents and potential generic competitors as a result of patent and regulatory exclusivity expirations.
The growth of our business is also dependent on our ability to continue to grow the appropriate use of DEFINITY in suboptimal echocardiograms. DEFINITY currently competes with ultrasound enhancing agents produced by GE Healthcare and Bracco, as well as echocardiography without ultrasound enhancing agents and other non-echocardiography agents.
We launched DEFINITY in 2001, and we continue to actively pursue additional patents in connection with DEFINITY and DEFINITY RT, both in the U.S. and internationally. In the U.S. for DEFINITY we have six Orange Book-listed method-of-use patents, one of which expires in 2035 and five of which expire in 2037, as well as additional manufacturing patents that are not Orange Book-listed expiring in 2037. In the U.S. for DEFINITY RT, we have eight Orange Book-listed patents, including two composition of matter patents that expire in 2035. Outside of the U.S., we are currently pursuing additional DEFINITY and DEFINITY RT patents to obtain similar patent protection as in the U.S. The Orange Book-listed patents include a patent on the use of VIALMIX RFID, which expires in 2037; additional VIALMIX RFID patent applications have been submitted in major markets throughout the world.
Because our Orange Book-listed composition of matter patent expired in June 2019, we may face generic DEFINITY challengers in the near to intermediate term. Under the Hatch-Waxman Act, the FDA can approve ANDAs for generic versions of drugs before the expiration of an Orange Book-listed patent covering the innovator product if the ANDA applicant demonstrates, among other things, that (i) its generic candidate is the same as the innovator product by establishing bioequivalence and providing relevant chemistry, manufacturing and product data, and (ii) either the marketing of that generic candidate does not infringe the Orange Book-listed patent(s) or the Orange Book-listed patent(s) is invalid. Similarly, the FDA can approve a Section 505(b)(2) NDA from an applicant that relies on some of the information required for marketing approval to come from studies which the applicant does not own or have a legal right of reference. The ANDA applicant or the Section 505(b)(2) applicant (if relying on studies related to the innovator product) (together, the “Applicant”) must also give Notice to the innovator, which would then enable the innovator to file suit against the Applicant within 45 days of receiving the Notice. If the innovator challenges the Applicant in court in a timely manner, then FDA approval to commercialize the generic candidate will be stayed (that is, delayed) for up to 30 months while the dispute between the innovator and the Applicant is resolved in court. The 30 month stay can be shortened if the patent infringement suit is resolved in the Applicant’s favor before the 30 month stay expires, and this may involve a successful challenge of the patent’s validity in U.S. Patent and Trademark Office (“USPTO”) proceedings and appeals process. In the event a 505(b)(2) applicant does not rely on studies related to the innovator product, the 30-month stay would not apply, but additional clinical trials may be required. We can give no assurance that we would have grounds to file a patent infringement suit, that we would obtain the full 30 month stay, that we would be successful on the merits asserting that an Applicant infringes our Orange Book-listed patent, or that we would be successful defending the validity of our Orange Book-listed patent in court or in a USPTO adversarial proceeding.
As of the date of filing of this Annual Report on Form 10-K, we have not received any such Notice from any Applicant, but we can give no assurance that we will not receive a Notice in the future. If we were to receive any such Notice in the future, we would review the Notice, evaluate the strength of any potential patent infringement claims, and be prepared to challenge the Applicant in a timely fashion, which would thereby trigger the stay of up to 30 months. We can give no assurance that we would have grounds to file a patent infringement suit, that we would obtain the full 30 month stay, that we would be successful on the merits asserting that an Applicant infringes our Orange Book-listed patent, or that we would be successful defending the validity of our Orange Book-listed patent in court or in a USPTO adversarial proceeding. If we were to receive such a Notice and to challenge the Applicant, patent litigation is complex and can be protracted and expensive, which could also have a negative effect on our business, results of operations and financial condition.

As part of our microbubble franchise strategy, (i) we have developed and received FDA approval for DEFINITY RT, a modified formulation of DEFINITY, (ii) we look for other opportunities to expand our microbubble franchise, including new applications beyond echocardiography and ultrasound enhancing agent imaging generally such as our strategic arrangements with Cerevast, CarThera, Insightec, AHN and SonoThera, and (iii) we have constructed a specialized in-house manufacturing facility at our North Billerica campus for purposes of producing the formulation of DEFINITY that requires refrigerated storage and, potentially, other sterile vial products. On February 22, 2022, we received FDA approval of our sNDA, authorizing commercial manufacturing of DEFINITY at our new facility. However, we can give no assurance that our microbubble franchise strategy will be successful or that the modified formulation, new applications or new manufacturing capabilities will grow our microbubble franchise.
If we are not able to continue to (i) grow DEFINITY and DEFINITY RT sales, which depend on one or more of the growth of echocardiograms, the growth in the appropriate use of ultrasound enhancing agents in suboptimal echocardiograms, and our ability to sustain and grow our leading position in the U.S. echocardiography ultrasound enhancing agent market, or (ii) be successful with our microbubble franchise strategy, we may not be able to continue to grow the revenue and cash flow of our business, which could have a negative effect on our business, results of operations and financial condition.
Our dependence upon third parties for the manufacture and supply of a substantial portion of our products and certain key components and raw materials and upon our in-house manufacturing for DEFINITY could prevent us from delivering our products to our customers in the required quantities, within the required timeframes, or at all, which could result in order cancellations and decreased revenues.
We obtain a substantial portion of our products from third party manufacturers and suppliers.
PYLARIFY is manufactured by a nationwide network of PMFs with radioisotope-producing cyclotrons. The radioisotope in PYLARIFY is fluorine-18, which has a 110-minute half-life, so PYLARIFY is manufactured and distributed rapidly to end-users. Because each of the PMFs manufacturing PLYARIFY is deemed by the FDA to be a separate manufacturing site, each has to be separately approved by the FDA. Although we have qualified and continue to qualify additional PMFs, we can give no assurance that the FDA will continue to approve PMFs in accordance with our planned roll-out schedule or that the PMFs will not experience issues with their ability to manufacture and deliver PYLARIFY to our customers. If FDA approval of manufacturing sites is delayed or withdrawn or our PMF sites experience manufacturing issues, our business, results of operations, financial condition and cash flows could be adversely affected.
We rely on JHS as a substantial supplier of DEFINITY, as well as our sole source manufacturer of NEUROLITE, CARDIOLITE and evacuation vials. We rely on Samsung Biologics Co., Ltd. (“SBL”) as our sole source manufacturer of DEFINITY RT. In addition, for reasons of quality assurance or cost-effectiveness, we purchase certain components and raw materials from sole suppliers (including, for example, the specially designed chemistry synthesis boxes and consumables used in the manufacturing of PYLARIFY, the lipid blend material and perflutren gas used in the manufacturing of DEFINITY and the lead casing for our TechneLite generators). Because we do not control the actual production of many of the products we sell and many of the raw materials and components that make up the products we sell, we may be subject to delays caused by interruption in production based on events and conditions outside of our control.
If we or one of our manufacturing partners or suppliers experiences an event, including a supply chain disruption, shortage or delay, logistics issue, labor dispute, natural disaster, fire, power outage, machinery breakdown, security problem, failure to meet regulatory requirements, product quality issue, technology transfer issue, cybersecurity breach or other issue, we or one of our manufacturing partners or suppliers may be unable to manufacture the relevant products at previous levels or on the forecasted schedule, if at all. Due to the stringent regulations and requirements of the governing regulatory authorities regarding the manufacture of our products, we may not be able to quickly restart manufacturing at a third party or our own facility or establish additional or replacement sources for certain products, components or materials.
In addition to our existing manufacturing relationships, we are also pursuing new manufacturing relationships to establish and secure additional or alternative suppliers for our commercial products. We also constructed a specialized in-house manufacturing facility at our North Billerica, Massachusetts campus for purposes of producing the formulation of DEFINITY that requires refrigerated storage and, potentially, other sterile vial products. On February 22, 2022, we received FDA approval of our sNDA, authorizing commercial manufacturing of DEFINITY at our new facility. This project provides a certain amount of supply chain redundancy for DEFINITY (other than DEFINITY RT, which is supplied solely by SBL). However, we cannot assure you that these activities or any of our additional supply activities will be successful or that we will be able to avoid or mitigate interim supply shortages before new sources of product are fully functional and qualified. In addition, we cannot assure you that our existing manufacturers or suppliers or any new manufacturers or suppliers can adequately maintain either their financial health, technical capabilities or regulatory compliance to allow continued production and supply. A reduction or interruption in manufacturing, or an inability to secure alternative sources of raw materials or components, could eventually have a material adverse effect on our business, results of operations, financial condition and cash flows.

The global supply of Mo-99 is fragile and not stable. Our dependence on a limited number of third party suppliers for Mo-99 could prevent us from delivering some of our products to our customers in the required quantities, within the required timeframe, or at all, which could result in order cancellations and decreased revenues.
A critical ingredient of TechneLite is Mo-99. We currently purchase finished Mo-99 from three of the four main processing sites in the world, namely IRE in Belgium, NTP in South Africa and ANSTO in Australia. These processing sites provide us Mo-99 from five of the six main Mo-99-producing reactors in the world, namely BR2 in Belgium, LVR-15 in the Czech Republic, HFR in The Netherlands, SAFARI in South Africa and OPAL in Australia.
Our agreement with NTP, acting for itself and on behalf of its subcontractor ANSTO, expires on December 31, 2024.
Although we have a globally diverse Mo-99 supply with IRE in Belgium, NTP in South Africa, and ANSTO in Australia, we still face supplier and logistical challenges in our Mo-99 supply chain. When one supplier experiences outages, we generally rely on Mo-99 supply from the other suppliers to limit the impact of the outages. We believe we effectively manage these various supply chain challenges, but depending on reactor and processor schedules and operations, at times we have not been able to fill some or all of the demand for our TechneLite generators on certain manufacturing days. A prolonged disruption of service from one of our three Mo-99 processing sites or one of their main Mo-99-producing reactors could have a substantial negative effect on our business, results of operations, financial condition and cash flows.
U.S., Canadian and international governments have encouraged the development of a number of alternative Mo-99 production projects with existing reactors and technologies as well as new technologies. However, we cannot say when, or if, the Mo-99 produced from these projects will become available. As a result, there is a limited amount of Mo-99 available which could limit the quantity of TechneLite that we could manufacture, sell and distribute, resulting in a substantial negative effect on our business, results of operations, financial condition and cash flows.
Most of the global suppliers of Mo-99 rely on Framatone-CERCA in France to fabricate uranium targets and in some cases fuel for research reactors from which Mo-99 is produced. Absent a new supplier, a supply disruption relating to uranium targets or fuel could have a substantial negative effect on our business, results of operations, financial condition and cash flows.
We can give no assurance that Curium will be successful with its commercialization of piflufolastat F 18 in Europe.
We have licensed exclusive rights to Curium to develop and commercialize piflufolastat F 18 in Europe. Under the terms of the collaboration, Curium is responsible for the development, regulatory approvals and commercialization of piflufolastat F 18 in Europe, and we are entitled to double-digit royalties on net sales of piflufolastat F 18. In July 2023, Curium announced that the EMA approved piflufolastat F 18 in Europe, under the name PYLCLARI. We cannot assure that Curium will be successful in commercializing it in Europe. Any failure or significant delay in Curium’s ability to successfully launch PYLCLARI in Europe may harm our business and delay or prevent us from being able to generate additional future royalty revenue from product sales.
We may not be able to successfully launch PYLARIFY AI as a commercial product.
We announced in November 2021 that PYLARIFY AI, our FDA-cleared medical device software, was commercially available in the United States. Our ability to successfully launch PYLARIFY AI as a commercial product depends in part on, among other things:
the market receptivity to PYLARIFY AI as a new digital application for quantitative assessment of PSMA PET/CT images in prostate cancer;
our ability, and our distributors’ abilities, to secure customers’ internal approvals and sell and deploy PYLARIFY AI at customer locations;
interruptions or performance problems associated with our digital application, including a service outage; and
a network or data security incident that allows unauthorized access to our network or data or our customers’ data.
Our just-in-time manufacturing of radiopharmaceutical products relies on the reliability of our equipment and processes, the timely receipt of radioactive raw materials and the timely shipment of finished goods, and any disruption of our supply or distribution networks could have a negative effect on our business.
At the facility on our North Billerica, Massachusetts campus, we manufacture TechneLite on an automated production line. As with all manufacturing facilities, equipment and infrastructure age and become subject to increasing maintenance and repair. If we experience an event, including a labor dispute, natural disaster, fire, power outage, machinery breakdown, security problem, failure to meet regulatory requirements, product quality issue, technology transfer issue or other issue, we may be unable to manufacture the relevant products at previous levels or on the forecasted schedule, if at all. Due to the stringent regulations and requirements of the

governing regulatory authorities regarding the manufacture of our products, we may not be able to quickly restart manufacturing at our facilities or establish additional or replacement sources for certain products, components or materials.
In addition, because a number of our radiopharmaceutical products, including PYLARIFY and our TechneLite generators rely on radioisotopes with limited half-lives, we or our partners must manufacture, finish and distribute these products on a just-in-time basis, because the underlying radioisotope is in a constant state of decay. For example, the radioisotope used in PYLARIFY is F 18, which has a 110 minute half-life, requiring that this product be manufactured and distributed within the same day to end-users. After being made on a cyclotron at a PMF, the F 18 is then combined with certain chemical ingredients in specially designed chemistry synthesis boxes to manufacture PYLARIFY. The finished PYLARIFY is then quality control tested and transferred to a radiopharmacist who prepares and dispenses patient-specific doses from the final product. Similarly, with respect to our TechneLite generators, if we receive Mo-99 in the morning of a manufacturing day for TechneLite generators, then we will generally ship finished generators to customers by the end of that same business day. Shipment of generators may be by next day delivery services or by either ground or air custom logistics. Any delay in us receiving radioisotopes from suppliers or being able to have finished products delivered to customers because of weather or other unforeseen transportation issues could have a negative effect on our business, results of operations, financial condition and cash flows.
In the U.S., we are heavily dependent on a few large customers to generate a majority of our revenues for our single-photon emission computerized tomography (SPECT) nuclear medical imaging products in our Precision Diagnostic product category. For PYLARIFY, we depend in part on some of our PMF partners to generate sales and collect revenue. Outside of the U.S., we rely primarily on distributors to generate a substantial portion of our revenue.
In the U.S., we have historically relied on a limited number of radiopharmacy customers, primarily Cardinal, RLS, UPPI, PharmaLogic and Jubilant Radiopharma, to purchase our nuclear imaging products in our Precision Diagnostic product category. Among the existing radiopharmacies in the U.S., continued consolidations, divestitures and reorganizations may have a negative effect on our business, results of operations, financial condition and cash flows. Our contractual arrangements with these radiopharmacy customers generally specify pricing levels and requirements to purchase minimum percentages of certain products during certain periods. The agreements generally may be terminated upon the occurrence of specified events, including a material breach by the other party and certain force majeure events. If these contracts are terminated prior to the expiration of their term, or are not renewed, or are renewed on terms that are less favorable to us, then such an event could have a material adverse effect on our business, results of operations, financial condition and cash flows.
For PYLARIFY, we depend in part on some of our PMF partners to generate sales and collect revenue. To the extent our PMF partners are unsuccessful in generating sales or in collecting revenue, such an event could have a material adverse effect on our business, results of operations, financial condition and cash flows.
We also continue to experience significant pricing pressures from our competitors, large customers and group purchasing organizations, and any significant, additional pricing pressures could lead to a reduction in revenue which could have a material adverse effect on our business, results of operations, financial condition and cash flows.
Outside of the U.S., we have no sales force and, consequently, rely on third party distributors, either on a country-by-country basis or on a multi-country, regional basis, to market, sell and distribute our products. In certain circumstances, distributors may also sell competing products to our own or products for competing diagnostic modalities and may have incentives to shift sales towards those competing products. As a result, we cannot assure you that our international distributors will increase or maintain current levels of unit sales or that we will be able to increase or maintain our current unit pricing, which, in turn, could have a material adverse effect on our business, results of operations, financial condition and cash flows.
We face significant competition in our business and may not be able to compete effectively.
The markets for our products are highly competitive and continually evolving. Our principal competitors for our current commercial products and leading clinical development candidates include large, global companies that are more diversified than we are and that have substantial financial, manufacturing, sales and marketing, distribution and other resources:
For PYLARIFY, our competitors currently include approved imaging agents from Telix Pharmaceuticals Limited, Novartis AG, and Blue Earth, a subsidiary of Bracco.
For DEFINITY, our competitors currently include GE Healthcare and Bracco.
For a number of our radiopharmaceutical commercial products, our competitors currently include Curium, GE Healthcare, Bracco and Jubilant Life Sciences, an affiliate of JHS and Jubilant Radiopharma, and potentially BWXT Medical.
For PNT2002 and 1095, our principal competitors may include Novartis AG; Telix Pharmaceuticals Limited; and Curium, each of which has commercialized products or product candidates in advanced clinical stage of development.

For PNT2003, our principal competitor may include Novartis AG; ITM Radiopharma; and RayzeBio (under agreement to be acquired by Bristoll Meyers Squibb), each of which has commercialized products or product candidates in advanced clinical stage of development.
For MK-6240, our principal competitors may include Eli Lilly and Company and Life Molecular Imaging, each of which has commercialized products or product candidates in advanced clinical stage of development. .
For LNTH-1363S, our principal competitors may include Sofie Bioscience; GE Healthcare; and Novartis AG, each of which has product candidates in clinical stage of development.
We cannot anticipate the actions of our current or future competitors in the same or competing modalities, such as significant price reductions on products that are competitive with our own, development of new products that are more cost-effective or have superior performance than our current products or potential future products or the introduction of generic versions after our proprietary products lose their patent protection. In addition, distributors of our products could attempt to shift end-users to competing diagnostic modalities and products, or bundle the sale of a portfolio of products, in either case to the detriment of our specific products. Our current or future products could be rendered obsolete or uneconomical as a result of these activities.
Further, the radiopharmaceutical industry continues to evolve strategically, with several market participants recently sold. In addition, the supply-demand dynamics of the industry are complex because of large market positions of some participants, legacy businesses, government subsidies (in particular, relating to the manufacture of radioisotopes), and group purchasing arrangements. We cannot predict what impact new owners and new operators may have on the strategic decision-making of our competitors, customers and suppliers, and such decision-making could have a material adverse effect on our business, results of operations, financial condition and cash flows.
Ultrasound enhancing agents may cause side effects which could limit our ability to sell DEFINITY.
DEFINITY is an ultrasound enhancing agent based on perflutren lipid microspheres. In 2007, the FDA received reports of deaths and serious cardiopulmonary reactions following the administration of ultrasound enhancing agents used in echocardiography. Four of the 11 reported deaths were caused by cardiac arrest occurring either during or within 30 minutes following the administration of the ultrasound enhancing agent; most of the serious but non-fatal reactions also occurred in this time frame. As a result, in October 2007, the FDA requested that we and GE Healthcare, which distributes Optison, a competitor to DEFINITY, add a boxed warning to these products emphasizing the risk for serious cardiopulmonary reactions and that the use of these products was contraindicated in certain patients. In a strong reaction by the cardiology community to the FDA’s new position, a letter was sent to the FDA, signed by 161 doctors, stating that the benefit of these ultrasound enhancing agents outweighed the risks and urging that the boxed warning be removed. In May 2008, the FDA substantially modified the boxed warning. On May 2, 2011, the FDA held an advisory committee meeting to consider the status of ultrasound enhancing agents and the boxed warning. In October 2011, we received FDA approval of further modifications to the DEFINITY label, including: further relaxing the boxed warning; eliminating the sentence in the Indication and Use section “The safety and efficacy of DEFINITY with exercise stress or pharmacologic stress testing have not been established” (previously added in October 2007 in connection with the imposition of the box warning); and including summary data from the post-approval CaRES (Contrast echocardiography Registry for Safety Surveillance) safety registry and the post-approval pulmonary hypertension study. Further, in January 2017, the FDA approved an additional modification to the DEFINITY label, removing the contraindication statement related to use in patients with a known or suspected cardiac shunt. Bracco’s ultrasound enhancing agent, Lumason, has substantially similar safety labeling as DEFINITY and Optison. In April 2021, after reviewing certain adverse events that occurred in patients with a prior history of allergic reactions to polyethylene glycol (“PEG”), an inactive excipient in both DEFINITY and Lumason, the FDA and the marketing authorization holders of these products agreed to an additional contraindication for use of these products, including advising clinicians to assess patients for prior PEG hypersensitivity before administering these products. In June 2023, after reviewing adverse events that occurred in patients with history of sickle cell disease, we agreed with the FDA to amend the label to advise clinicians that if a patient with sickle cell disease experiences acute pain episodes following DEFINITY administration, use of DEFINITY in that patient should be discontinued. If additional safety issues arise (not only with DEFINITY but also potentially with Optison and Lumason), this may result in unfavorable changes in labeling or result in restrictions on the approval of our product, including removal of the product from the market. Lingering safety concerns about DEFINITY among some healthcare providers or future unanticipated side effects or safety concerns associated with DEFINITY could limit expanded use of DEFINITY and have a material adverse effect on the unit sales of this product and our financial condition and results of operations.

Risks Related to Reimbursement and Regulation
Many of our customers are highly dependent on payments from third-party payors, including government sponsored programs, particularly Medicare, in the U.S. and other countries in which we operate, and reductions in third party coverage and reimbursement rates for our products (or services provided with our products) could adversely affect our business and results of operations.
A substantial portion of our revenue depends on the extent to which the costs of our products purchased by our customers (or services provided with our products) are reimbursed by third party payors, including Medicare, Medicaid, other U.S. government sponsored programs, non-U.S. governmental payors and private payors. These third-party payors exercise significant control over patient access and increasingly use their enhanced bargaining power to secure discounted rates and impose other requirements that may reduce demand for our products. Our customers’ ability to obtain adequate reimbursement for products and services from these third-party payors affects the selection of products they purchase and the prices they are willing to pay. If Medicare and other third party payors do not provide adequate reimbursement for the costs of our products (or services provided using our products), deny the coverage of the products (or those services), or reduce current levels of reimbursement, healthcare professionals may not prescribe our products and providers and suppliers may not purchase our products.
In addition, demand for new products may be limited unless we obtain favorable reimbursement (including coding, coverage and payment) from governmental and private third party payors at the time of the product’s introduction, which will depend, in part, on our ability to demonstrate that a new agent has a positive impact on clinical outcomes. Third-party payors continually review their coverage policies for existing and new products and procedures and can deny coverage for products or procedures that include the use of our products or revise payment policies such that payments do not adequately cover the cost of our products. Even if third-party payors make coverage and reimbursement available, that reimbursement may not be adequate or these payors’ reimbursement policies may have an adverse effect on our business, results of operations, financial condition and cash flows.
For example, effective January 1, 2022, the CMS granted TPT Status in the hospital outpatient setting for PYLARIFY, enabling traditional Medicare to provide an incremental payment for PET/CT scans performed with PYLARIFY in that setting. TPT Status for PYLARIFY is expected to expire December 31, 2024. After TPT Status expires, under current Medicare rules, PYLARIFY would not be separately reimbursed in the hospital outpatient setting but rather would be bundled into the facility payment a hospital receives for a PET/CT imaging procedure, and the facility payment may not always cover the total cost of the procedure. In 2023 rulemaking for the 2024 payment calendar year, CMS recognized the challenges of patient access to diagnostic radiopharmaceuticals and requested feedback on various payment alternatives that could provide separate reimbursement for these items, but the agency did not adopt any of these proposals in the final rule, while stating that it would continue to evaluate this issue in subsequent rulemaking. We can give no assurance that any CMS reimbursement in the hospital outpatient setting that follows the expiration of TPT Status will be adequate to cover a PYLARIFY PET/CT imaging procedure or that the availability of TPT Status for other diagnostic radiopharmaceuticals will not impact clinical decision making regarding which product to use, which could have an adverse effect on our business, results of operations, financial condition and cash flows.
Over the past several years, Medicare has implemented numerous changes to payment policies for imaging procedures in both the hospital setting and non-hospital settings (which include physician offices and freestanding imaging facilities). Some of these changes have had a negative impact on utilization of imaging services. Examples of these changes include:
Reducing payments for certain imaging procedures when performed together with other imaging procedures in the same family of procedures on the same patient on the same day in the physician office and free-standing imaging facility setting;
Making significant revisions to the methodology for determining the practice expense component of the Medicare payment applicable to the physician office and free-standing imaging facility settings which results in a reduction in payment;
Revising payment policies and reducing payment amounts for imaging procedures performed in the hospital outpatient settings; and
Reducing prospective payment levels for applicable diagnosis-related groups in the hospital inpatient setting.
In the physician office and free-standing imaging facility setting, services provided using our products are reimbursed under the Medicare physician fee schedule. Payment rates under the Medicare physician fee schedule are regularly subject to updates to effectuate various policy goals of CMS and Congress. For example, in 2022, CMS reduced Medicare fee schedule payments rates in the agency’s final rulemaking, while a larger cut was put forth in the proposed rulemaking earlier that year. For 2023, CMS had finalized a reduction in the Medicare fee schedule payments rates, which was revised by Congress, pursuant to the Consolidated Appropriations Act, 2023, to a lesser reduction. Additionally, since 2019, fee schedule payments have been adjusted for certain physicians based on their performance under a consolidated measurement system (that measures performance with respect to quality, resource utilization, meaningful use of certified electronic health records technology, and clinical practice improvement activities).

Table of Contents

From 2019 through payment year 2024, physicians may be eligible for a bonus based on the use of certain alternative payment models designated as “advanced” by CMS. The ongoing and future impact of these changes cannot be determined at this time.
We believe that Medicare changes to payment policies for imaging procedures applicable to non-hospital settings will continue to result in certain physician practices ceasing to provide these services and a further shifting of where certain medical imaging procedures are performed, from the physician office and free-standing imaging facility settings to the hospital outpatient setting. Changes applicable to Medicare payment in the hospital outpatient setting could also influence the decisions by hospital outpatient physicians to perform procedures that involve our products. Within the hospital outpatient setting, CMS payment policy is such that the use of many of our products are not separately payable by Medicare, although certain new drug products are eligible for separate (incremental) payment for the first three years after approval. Changes to the Medicare hospital outpatient prospective payment system payment rates, including reductions implemented for certain hospital outpatient sites, could influence the decisions by hospital outpatient physicians to perform procedures that involve our products.
We also believe that all of these changes and their resulting pressures may incrementally reduce the overall number of diagnostic medical imaging procedures performed. These changes overall could slow the acceptance and introduction of next-generation imaging equipment into the marketplace, which, in turn, could adversely impact the future market adoption of certain of our imaging agents already in the market or currently in development. We expect that there will continue to be proposals to reduce or limit Medicare and Medicaid payment for diagnostic services, which could impact our current or potential future diagnostic and other types of products and have a material adverse effect on our business, results of operations, financial condition and cash flows.
We also expect increased regulation and oversight of advanced diagnostic testing in which our products are used, although the timing of such regulation is uncertain after a recent pause by CMS. Under section 218(b) of the Protecting Access to Medicare Act, beginning January 1, 2020, a professional who is ordering advanced diagnostic imaging services (which include MRI, CT, nuclear medicine (including PET) and other advanced diagnostic imaging services that the Secretary of HHS may specify, but not currently including echocardiography) must consult a qualified clinical decision support mechanism, as identified by HHS, to determine whether the ordered service adheres to specified appropriate use criteria (“AUC”) developed or endorsed by CMS-qualified “provider led entities”. Medicare claims for such services must include information indicating whether services ordered would adhere to specified applicable AUC. Denial of claims for failure to include AUC consultation information on the claim form was set to begin on January 1, 2022, but was not implemented by CMS. In the CY 2024 Physician Fee Schedule Final Rule, CMS determined that it was not feasible to fully operationalize the AUC program consistent with the statute within the required time frame. Accordingly, the agency finalized an indefinite pause to the AUC program and the recission of the regulations promulgated thus far to implement the AUC program. While it is unclear when CMS will resume implementation of the AUC program, to the extent that these types of changes have the effect of reducing the aggregate number of diagnostic medical imaging procedures performed in the U.S., our business, results of operations, financial condition and cash flows would be adversely affected.
Medicare coverage of PET radiopharmaceuticals has been the subject of a large number of National Coverage Determinations (“NCDs”) by CMS since 2000. Specific indications for PET imaging were covered, some through Coverage with Evidence Development. CMS’s longtime policy, however, was that a particular use of PET scans is not covered unless an NCD specifically provided that such use was covered. Effective March 7, 2013, CMS revised its policy through an NCD to allow local Medicare Administrative Contractors (“MACs”) to determine coverage within their respective jurisdictions for PET using radiopharmaceuticals for their FDA-approved labeled indications for oncologic imaging. Effective January 1, 2022, non-coverage in the absence of an NCD has also been removed for non-oncologic indications of PET radiopharmaceuticals, allowing MACs to determine coverage for these indications within their respective jurisdictions. To the extent that CMS or the MACs impose more restrictive coverage, our business, results of operations, financial condition and cash flows would be adversely affected.
Reforms to the U.S. healthcare system may adversely affect our business.
A significant portion of our patient volume is derived from U.S. government healthcare programs, principally Medicare, which are highly regulated and subject to frequent and substantial changes. The Healthcare Reform Act substantially changed the way healthcare is financed by both governmental and private insurers. The law contains a number of provisions that affect coverage and reimbursement of drug products and medical imaging procedures in which our drug products are used and/or that could potentially reduce the aggregate number of diagnostic medical imaging procedures performed in the U.S. Subsequently, the Medicare Access and CHIP Reauthorization Act of 2015 significantly revised the methodology for updating the Medicare physician fee schedule. In 2017, Congress enacted legislation that effectively eliminated the Healthcare Reform Act’s “individual mandate” beginning in 2019. Congress continues to consider other healthcare reform legislation. There is no assurance that the Healthcare Reform Act, as currently enacted or as amended in the future, will not adversely affect our business and financial results, and we cannot predict how future federal or state legislative, judicial or administrative changes relating to healthcare reform will affect our business.
36

Table of Contents

In addition, other legislative changes have been proposed and adopted since the Healthcare Reform Act was enacted. The Budget Control Act of 2011 and subsequent Congressional actions includes provisions to reduce the federal deficit. These provisions have resulted in the imposition of 2% reductions in Medicare payments to providers, which went into effect on April 1, 2013 and will remain in effect through fiscal year 2030. The imposition of the 2% payment adjustment had been suspended through March 31, 2022 and went into effect as of April 1, 2022. Any significant spending reductions affecting Medicare, Medicaid or other publicly funded or subsidized health programs that may be implemented and/or any significant taxes or fees that may be imposed on us, as part of any broader deficit reduction effort or legislative replacement to the Budget Control Act, could have an adverse impact on our business, results of operations, financial condition and cash flows.
Further, changes in payor mix and reimbursement by private third-party payors may also affect our business. Rates paid by some private third-party payors are based, in part, on established physician, clinic and hospital charges and are generally higher than Medicare payment rates. Reductions in the amount of reimbursement paid for diagnostic medical imaging procedures, including the elimination of any additional payment such as TPT Status, and changes in the mix of our patients between non-governmental payors and government sponsored healthcare programs and among different types of non-government payor sources, could have a material adverse effect on our business, results of operations, financial condition and cash flows.
The full impact on our business of healthcare reforms and other new laws, or changes in existing laws, is uncertain. Nor is it clear whether additional legislative changes will be adopted or how those changes would affect our industry in general or our ability to successfully commercialize our products or develop or commercialize new products.
Our business and industry are subject to complex and costly regulations. If government regulations are interpreted or enforced in a manner adverse to us or our business, we may be subject to enforcement actions, penalties, exclusion and other material limitations on our operations.
Both before and after the approval of our products in development, we, our products, development products, operations, facilities, suppliers, distributors, contract manufacturers, contract research organizations and contract testing laboratories are subject to extensive and, in certain circumstances, expanding regulation by federal, state and local government agencies in the U.S. as well as non-U.S. and transnational laws and regulations, with regulations differing from country to country and even state to state, including, among other things, anti-trust and competition laws and regulations, and data privacy laws and regulations such as the General Data Protection Regulation in the European Union and the CCPA and the CPRA. In the U.S., the FDA regulates, among other things, the pre-clinical testing, clinical trials, manufacturing, safety, efficacy, potency, labeling, storage, record keeping, quality systems, advertising, promotion, sale, distribution, and import and export of drug products. We are required to register our business for permits and/or licenses with, and comply with the stringent requirements of the FDA, the NRC, the HHS, Health Canada, the EMA, the MHRA, the NMPA, state and provincial boards of pharmacy, state and provincial health departments and other federal, state and provincial agencies. Violation of any of these regulatory schemes, individually or collectively, could disrupt our business and have a material adverse effect on our business, results of operations, financial condition and cash flows.
Under U.S. law, for example, we are required to report certain adverse events and production problems, if any, to the FDA or other federal or state regulators. We also have similar adverse event and production reporting obligations outside of the U.S., including to the EMA and MHRA. Additionally, we must comply with requirements concerning advertising and promotion for our products, including the prohibition on the promotion of our products for indications for which they have not been approved by the FDA or a so-called “off-label use” or promotion that is inconsistent with the approved labeling. If the FDA determines that our promotional materials constitute unlawful promotion, it could request that we modify our promotional materials or subject us to regulatory or enforcement actions. Also, quality control and manufacturing procedures at our own facility and at third-party suppliers must conform to cGMP regulations and other applicable law after approval, and the FDA periodically inspects manufacturing facilities to assess compliance with cGMPs and other applicable law, and, from time to time, makes those cGMPs more stringent. Accordingly, we and others with whom we work must expend time, money, and effort in all areas of regulatory compliance, including manufacturing, production and quality control. If in the future issues arise at our own manufacturing facility or at a third-party manufacturer, the FDA could take regulatory action which could limit or suspend the ability to manufacture our products or have any additional products approved at the relevant facility for manufacture until the issues are resolved and remediated. Such a limitation or suspension could have a material adverse effect on our business, results of operations, financial condition and cash flows.
We are also subject to laws and regulations that govern financial and other arrangements between pharmaceutical manufacturers and healthcare providers, including federal and state anti-kickback statutes, federal and state false claims laws and regulations, federal and state “sunshine” laws and regulations and other fraud and abuse laws and regulations.
We must offer discounted pricing or rebates on purchases of pharmaceutical products under various federal and state healthcare programs, such as the Medicaid drug rebate program, the 340B drug pricing program and the Medicare Part D Program. We must also report specific prices to government agencies under healthcare programs, such as the Medicaid drug rebate program and Medicare Part B. Our Medicaid Drug Rebate agreements require us to report certain price information to the federal government. Determination of
37

Table of Contents

the rebate amount that we pay to state Medicaid programs for our products, of prices charged to government and certain private payors for our products, or of amounts paid for our products under government healthcare programs, depends upon information reported by us to the government. If we provide customers or government officials with inaccurate information about the products’ pricing or eligibility for coverage, or the products fail to satisfy coverage requirements, we could be terminated from the rebate program, be excluded from participation in government healthcare programs, or be subject to potential liability under the False Claims Act or other laws and regulations.
Failure to comply with other requirements and restrictions placed upon us or our third-party manufacturers or suppliers by laws and regulations can result in fines, civil and criminal penalties, exclusion from federal healthcare programs and debarment. Possible consequences of those actions could include:
Substantial modifications to our business practices and operations;
Significantly reduced demand for our products (if products become ineligible for reimbursement under federal and state healthcare programs);
A total or partial shutdown of production in one or more of the facilities where our products are produced while the alleged violation is being remediated;
Delays in or the inability to obtain future pre-market clearances or approvals; and
Withdrawals or suspensions of our current products from the market.
Our marketing and sales practices may contain risks that could result in significant liability, require us to change our business practices, and restrict our operations in the future.
We are subject to numerous domestic (federal, state and local) and foreign laws addressing fraud and abuse in the healthcare industry, including the FCA and federal Anti-Kickback Statute, self-referral laws, the FCPA, the Bribery Act, FDA promotional restrictions, the federal disclosure (sunshine) law and state marketing and disclosure (sunshine) laws. Violations of these laws are punishable by criminal or civil sanctions, including substantial fines, imprisonment and exclusion from participation in healthcare programs such as Medicare and Medicaid as well as health programs outside the U.S., and even settlement of alleged violations can result in the imposition of corporate integrity agreements that could subject us to additional compliance and reporting requirements and impact our business practices. These laws and regulations are complex and subject to changing interpretation and application, which could restrict our sales or marketing practices. Even minor and inadvertent irregularities could potentially give rise to a charge that the law has been violated. Although we believe we maintain an appropriate compliance program, we cannot be certain that the program will adequately detect or prevent violations and/or the relevant regulatory authorities may disagree with our interpretation. Additionally, if there is a change in law, regulation or administrative or judicial interpretations, we may have to change one or more of our business practices to be in compliance with these laws. Required changes could be costly and time consuming.
If our operations are found to be in violation of these laws or any other government regulations that apply to us, we may be subject to penalties, including, without limitation, civil and criminal penalties, damages, fines, imprisonment, the curtailment or restructuring of our operations, or exclusion from state and federal healthcare programs including Medicare and Medicaid, any of which could have a material adverse effect on our business, results of operations, financial condition and cash flows.
Risks Related to Our Business Operations and Financial Results
We may not be able to hire or retain the number of qualified personnel, particularly scientific, medical and sales personnel, required for our business, which would harm the development and sales of our products and limit our ability to grow.
Competition in our industry for highly skilled scientific, healthcare and sales personnel is intense. In connection with the launch and continued growth of PYLARIFY, we hired additional employees to assist us with the commercialization of PYLARIFY, including in sales, marketing, reimbursement, quality and medical affairs. Although we were successful in hiring and onboarding those employees and we have not had any material difficulty in the past in hiring or retaining qualified personnel, if we are unable to retain our existing personnel, or attract and train additional qualified personnel, either because of competition in our industry for these personnel or insufficient financial resources, then our growth may be limited and it could have a material adverse effect on our business.
If we lose the services of our key personnel, our business could be adversely affected.
Our success is substantially dependent upon the performance, contributions and expertise of our chief executive officer, executive leadership and senior management team. Mary Anne Heino, our Chief Executive Officer, and other members of our executive leadership and senior management team play a significant role in formulating and executing on our long-term strategy, generating business and overseeing operations. We have employment agreements with Ms. Heino, Brian Markison, who will succeed Ms. Heino as Chief Executive Officer effective March 1, 2024, and a limited number of other individuals on our executive leadership

team, although we cannot prevent them from terminating their employment with us. We do not maintain key person life insurance policies on any of our executive officers. While we have experienced some turnover on our executive leadership team, we have generally been able to fill positions by either promoting existing employees or attracting new, qualified individuals to lead key functional areas. For example, on January 23, 2024, we announced that effective March 1, 2024, Brian Markison, our current Chair of the Board, will become our Chief Executive Officer, and Mary Anne Heino, our current Chief Executive Officer, will retire and become the Chair of the Board. Our inability to retain our existing executive leadership and senior management team, maintain an appropriate internal succession program or attract and retain additional qualified personnel could have a material adverse effect on our business.
Our business depends on our ability to successfully introduce new products and adapt to a changing technology and medical practice landscape.
The healthcare industry is characterized by continuous technological development resulting in changing customer preferences and requirements. The success of new product development depends on many factors, including our ability to fund development of new products or new indications for existing products, anticipate and satisfy customer needs, obtain timely regulatory approval based on performance of our products in development versus their clinical trial comparators, develop and manufacture products in a cost-effective and timely manner, maintain advantageous positions with respect to intellectual property and differentiate our products from our competitors. To compete successfully in the marketplace, we must make substantial investments in new product development, whether internally or externally through licensing or acquisitions. Our failure to introduce new and innovative products in a timely manner would have an adverse effect on our business, results of operations, financial condition and cash flows.
Even if we are able to develop, manufacture and obtain regulatory approvals for our new products, the success of these products would depend upon market acceptance and adequate coding, coverage and payment. Levels of market acceptance for our new products could be affected by a number of factors, including:
The availability of alternative products from our competitors;
The breadth of indications in which alternative products from our competitors can be marketed;
The price of our products relative to those of our competitors;
The timing of our market entry;
Our ability to enter into commercial contracts to sell our products;
Our ability to market and distribute our products effectively;
Market acceptance of our products; and
Our ability to obtain adequate coding, coverage and payment, including the availability of TPT Status.
The field of diagnostic medical imaging is dynamic, with new products, including equipment, software and products, continually being developed and existing products continually being refined. Our own diagnostic imaging agents compete not only with other similarly administered imaging agents but also with imaging agents employed in different and often competing diagnostic modalities, and in the case of DEFINITY, echocardiography procedures without ultrasound enhancing agents. New hardware, software or products in a given diagnostic modality may be developed that provide benefits superior to the then-dominant hardware, software and products in that modality, resulting in commercial displacement of the products. Similarly, changing perceptions about comparative efficacy and safety including, among other things, comparative radiation exposure, as well as changing availability of supply or the availability of additional payments for new devices such as TPT Status, may favor one product over another or one modality over another. In addition, new or revised appropriate use criteria developed by professional societies, to assist physicians and other health care providers in making appropriate imaging decisions for specific clinical conditions, can and have reduced the frequency of and demand for certain imaging modalities and imaging agents. To the extent there is technological obsolescence in any of our products that we manufacture, resulting in lower unit sales or decreased unit sales prices, we will have increased unit overhead allocable to the remaining market share, which could have a material adverse effect on our business, results of operations, financial condition and cash flows. Similar risks could apply to therapeutic products, including products we are developing.
Our future growth may depend on our ability to identify and acquire or in-license additional products, businesses or technologies, and if we do not successfully do so, or otherwise fail to integrate any new products, lines of business or technologies into our operations, we may have limited growth opportunities and it could result in significant impairment charges or other adverse financial consequences.
We seek to acquire or in-license products, businesses or technologies that we believe are a strategic fit with our business strategy. Future acquisitions or in-licenses, however, may entail numerous operational and financial risks, including:
A reduction of our current financial resources;
39

Table of Contents

Incurrence of substantial debt or dilutive issuances of securities to pay for acquisitions;
Difficulty or inability to secure financing to fund development activities for those acquired or in-licensed technologies;
Higher than expected acquisition and integration costs;
Disruption of our business, customer base and diversion of our management’s time and attention to develop acquired products or technologies; and
Exposure to unknown liabilities.
We may not have sufficient resources to identify and execute the acquisition or in-licensing of third-party products, businesses and technologies and integrate them into our current infrastructure. In particular, we may compete with larger pharmaceutical companies and other competitors in our efforts to establish new collaborations and in-licensing opportunities. These competitors likely will have access to greater financial resources than we do and may have greater expertise in identifying and evaluating new opportunities. Furthermore, there may be an overlap between our products or customers and the companies which we acquire that may create conflicts in relationships or other commitments detrimental to the integrated businesses. Additionally, the time between our expenditures to acquire or in-license new products, technologies or businesses and the subsequent generation of revenues from those acquired products, technologies or businesses (or the timing of revenue recognition related to licensing agreements and/or strategic collaborations) could cause fluctuations in our financial performance from period to period. Finally, if we devote resources to potential acquisitions or in-licensing opportunities that are never completed, or if we fail to realize the anticipated benefits of those efforts, we could incur significant impairment charges or other adverse financial consequences.
Challenges with product quality or product performance, including defects, caused by us or our manufacturers or suppliers could result in a decrease in customers and revenues, unexpected expenses and loss of market share.
The manufacture of our products is highly exacting and complex and must meet stringent quality requirements, due in part to strict regulatory requirements, including the FDA’s cGMPs. Problems may be identified or arise during manufacturing, quality review, packaging or shipment for a variety of reasons including equipment malfunction, failure to follow specific protocols and procedures, defective raw materials and environmental factors. Additionally, manufacturing flaws, component failures, design defects, off-label uses or inadequate disclosure of product-related information could result in an unsafe condition or the injury or death of a patient. Those events could lead to a recall of, or issuance of a safety alert relating to, our products or could harm our reputation and our ability to market our products in the future. We also may undertake voluntarily to recall products or temporarily shut down production lines based on internal safety and quality monitoring and testing data.
Quality, regulatory and recall challenges could cause us to incur significant costs, including costs to replace products, lost revenue, damage to customer relationships, time and expense spent investigating the cause and costs of any possible settlements or judgments related thereto and potentially cause similar losses with respect to other products. These challenges could also divert the attention of our management and employees from operational, commercial or other business efforts. If we deliver products with defects, or if there is a perception that our products or the processes related to our products contain errors or defects, we could incur additional recall and product liability costs, and our credibility and the market acceptance and sales of our products could be materially adversely affected. Due to the strong name recognition of our brands, an adverse event involving one of our products could result in reduced market acceptance and demand for all products within that brand, and could harm our reputation and our ability to market our products in the future. In some circumstances, adverse events arising from or associated with the design, manufacture or marketing of our products could result in the suspension or delay of regulatory reviews of our applications for new product approvals. These challenges could have a material adverse effect on our business, results of operations, financial condition and cash flows.
In the ordinary course of business, we may be subject to product liability claims and lawsuits, including potential class actions, alleging that our products have resulted or could result in an unsafe condition or injury.
Any product liability claim brought against us, with or without merit, could be time consuming and costly to defend and could result in an increase of our insurance premiums. Although we have not had any such claims to date, claims that could be brought against us might not be covered by our insurance policies. Furthermore, although we currently have product liability insurance coverage with policy limits that we believe are customary for pharmaceutical companies in the diagnostic medical imaging industry and adequate to provide us with insurance coverage for foreseeable risks, even where the claim is covered by our insurance, our insurance coverage might be inadequate and we would have to pay the amount of any settlement or judgment that is in excess of our policy limits. We may not be able to obtain insurance on terms acceptable to us or at all, since insurance varies in cost and can be difficult to obtain. Our failure to maintain adequate insurance coverage or successfully defend against product liability claims could have a material adverse effect on our business, results of operations, financial condition and cash flows.
We use hazardous materials in our business and must comply with environmental laws and regulations, which can be expensive.
40

Table of Contents

Our operations use hazardous materials and produce hazardous wastes, including radioactive, chemical and, in certain circumstances, biological materials and wastes. We are subject to a variety of federal, state and local laws and regulations as well as non-U.S. laws and regulations relating to the transport, use, handling, storage, exposure to and disposal of these materials and wastes. Environmental laws and regulations are complex, change frequently and have generally become more stringent over time. We are required to obtain, maintain and renew various environmental permits and nuclear licenses. Although we believe that our safety procedures for transporting, using, handling, storing and disposing of, and limiting exposure to, these materials and wastes comply in all material respects with the standards prescribed by applicable laws and regulations, the risk of accidental contamination or injury cannot be eliminated. We place a high priority on these safety procedures and seek to limit any inherent risks. We generally contract with third parties for the disposal of wastes generated by our operations. We store low level radioactive waste at our facility and dispose of the materials in accordance with applicable laws and regulations. A majority of our low level radioactive waste is held to decay until materials are no longer considered radioactive. Although we believe we have complied in all material respects with all applicable environmental, health and safety laws and regulations, we cannot assure you that we have been or will be in compliance with all such laws at all times. If we violate these laws, we could be fined, criminally charged or otherwise sanctioned by regulators. We may be required to incur further costs to comply with current or future environmental and safety laws and regulations. In addition, in the event of accidental contamination or injury from these materials, we could be held liable for any damages that result and any such liability could exceed our resources.
We previously leased a small portion of our North Billerica, Massachusetts campus to PerkinElmer for the manufacturing, finishing and packaging of certain radioisotopes, including Strontium-90, which has physical characteristics that make it more challenging to work with and dispose of than our own commercial radioisotopes, including a much longer half-life. PerkinElmer decommissioned its space and vacated the premises as of December 30, 2021. We are fully indemnified by PerkinElmer under our lease for any property damage or personal injury resulting from their activities in our facility. If any release or excursion of radioactive materials took place from their leased space that resulted in property damage or personal injury, the indemnification obligations were not honored, and we were forced to cover any related remediation, clean-up or other expenses, depending on the magnitude, the cost of such remediation, clean-up or other expenses could have a material adverse effect on our business, results of operations, financial condition and cash flows.
While we have budgeted for current and future capital and operating expenditures to maintain compliance with these laws and regulations, we cannot assure you that our costs of complying with current or future environmental, health and safety laws and regulations will not exceed our estimates or adversely affect our results of operations and financial condition. Further, we cannot assure you that we will not be subject to additional environmental claims for personal injury, investigation or cleanup in the future based on our past, present or future business activities.
If we are unable to protect our intellectual property, our competitors could develop and market products with features similar to our products, and demand for our products may decline.
Our commercial success will depend in part on obtaining and maintaining patent and trade secret protection of our commercial products and technologies and products in development as well as successfully enforcing and defending these patents and trade secrets against third parties and their challenges, both in the U.S. and in foreign countries. We will only be able to protect our intellectual property from unauthorized use by third parties to the extent that we maintain the secrecy of our trade secrets and can enforce our valid patents and trademarks.
The patent positions of pharmaceutical and biotechnology companies can be highly uncertain and involve complex legal and factual questions for which important legal principles remain unresolved. In addition, changes in either the patent laws or in interpretations of patent laws in the U.S. or other countries may diminish the value of our intellectual property and we may not receive the same degree of protection in every jurisdiction. Accordingly, we cannot predict the breadth of claims that may be allowed or enforced in our patents or in third-party patents.
The degree of future protection for our proprietary rights is uncertain because legal means afford only limited protection and may not adequately protect our rights or permit us to gain or keep our competitive advantage. For example:
We might not have been the first to make the inventions covered by each of our pending patent applications and issued patents, and we could lose our patent rights as a result;
We might not have been the first to file patent applications for these inventions or our patent applications may not have been timely filed, and we could lose our patent rights as a result;
Others may independently develop similar or alternative technologies or duplicate any of our technologies;
It is possible that none of our pending patent applications will result in any further issued patents;
Our issued patents may not provide a basis for commercially viable drugs, may not provide us with any protection from unauthorized use of our intellectual property by third parties, and may not provide us with any competitive advantages;
41

Table of Contents

The validity or enforceability of our patent applications or patents may be subject to challenge through interferences, oppositions, post-grant review, ex-parte re-examinations, inter partes review or similar administrative proceedings;
While we generally apply for patents in those countries where we intend to make, have made, use or sell patented products, we may not be able to accurately predict all of the countries where patent protection will ultimately be desirable and may be precluded from doing so at a later date;
We may choose not to seek patent protection in certain countries where the actual cost outweighs the perceived benefit at a certain time;
Patents issued in foreign jurisdictions may have different scopes of coverage than our U.S. patents and so our products may not receive the same degree of protection in foreign countries as they would in the U.S.;
We may not develop additional proprietary technologies that are patentable;
The patents of others may have an adverse effect on our business; or
The cost to defend our patents may be significant and may result in litigation which could be costly and time consuming.
Moreover, the issuance of a patent is not conclusive as to its validity or enforceability. A third party may challenge the validity or enforceability of a patent even after its issuance by the USPTO or the applicable foreign patent office. It is also uncertain how much protection, if any, will be afforded by our patents if we attempt to enforce them and they are challenged in court or in other proceedings, which may be brought in U.S. or non-U.S. jurisdictions to challenge the validity of a patent.
The initiation, defense and prosecution of intellectual property suits (including Hatch-Waxman related litigation), interferences, oppositions and related legal and administrative proceedings are costly, time consuming to pursue and result in a diversion of resources, including a significant amount of management time. The outcome of these proceedings is uncertain and could significantly harm our business. If we are not able to enforce and defend the patents of our technologies and products, then we will not be able to exclude competitors from marketing products that directly compete with our products, which could have a material and adverse effect on our business, results of operations, financial condition and cash flows.
We also rely on trade secrets and other know-how and proprietary information to protect our technology, especially where we do not believe patent protection is appropriate or obtainable. However, trade secrets are difficult to protect. We use reasonable efforts to protect our trade secrets, but our employees, consultants, contractors, outside scientific partners and other advisors may unintentionally or willfully disclose our confidential information to competitors or other third parties. Enforcing a claim that a third party improperly obtained and is using our trade secrets is expensive, time consuming and resource intensive, and the outcome is unpredictable. In addition, courts outside the U.S. are sometimes less willing to protect trade secrets. Moreover, our competitors may independently develop equivalent knowledge, methods and know-how. We rely on confidentiality agreements with our collaborators, employees, consultants and other third parties and invention assignment agreements with our employees to protect our trade secrets and other know-how and proprietary information concerning our business. These confidentiality agreements may not prevent unauthorized disclosure of trade secrets and other know-how and proprietary information, and there can be no guarantee that an employee or an outside party will not make an unauthorized disclosure of our trade secrets, other technical know-how or proprietary information, or that we can detect such an unauthorized disclosure. We may not have adequate remedies for any unauthorized disclosure. This might happen intentionally or inadvertently. It is possible that a competitor will make use of that information, and that our competitive position will be compromised, in spite of any legal action we might take against persons making those unauthorized disclosures, which could have a material and adverse effect on our business, results of operations, financial condition and cash flows.
We rely on our trademarks, trade names and brand names to distinguish our products from the products of our competitors, and have registered or applied to register many of these trademarks. We cannot assure you that any pending trademark applications will be approved. Third parties may also oppose our trademark applications, or otherwise challenge our use of the trademarks. If our trademarks are successfully challenged, we could be forced to re-brand our products, which could result in loss of brand recognition, and could require us to devote resources to advertising and marketing new brands. Further, we cannot assure you that competitors will not infringe our trademarks, or that we will have adequate resources to enforce our trademarks.
Our patents are subject to generic challenge, and the validity, enforceability and commercial value of these patents are highly uncertain.
Our ability to obtain and defend our patents impacts the commercial value of our products and product candidates. Third parties have challenged and are likely to continue challenging the patents that have been issued or licensed to us. Patent protection involves complex legal and factual questions and, therefore, enforceability is uncertain. Our patents may be challenged, invalidated, held to be unenforceable, or circumvented, which could negatively impact their commercial value. Furthermore, patent applications filed outside the United States may be challenged by other parties, for example, by filing third-party observations that argue against patentability or an opposition. Such opposition proceedings are increasingly common in the EU and are costly to defend.

We may be subject to claims that we have infringed, misappropriated or otherwise violated the patent or other intellectual property rights of a third party. The outcome of any of these claims is uncertain and any unfavorable result could adversely affect our business, financial condition and results of operations.
We may be subject to claims by third parties that we have infringed, misappropriated or otherwise violated their intellectual property rights. We are aware of intellectual property rights held by third parties that relate to products or technologies we are developing. For example, we are aware of other groups investigating PSMA or related compounds and monoclonal antibodies directed at PSMA, PSMA-targeted imaging agents and therapeutics, and methylnaltrexone and other peripheral opioid antagonists, and of patents held, and patent applications filed, by these groups in those areas. While the validity of these issued patents, the patentability of pending patent applications and the applicability of any of them to our products and programs are uncertain, if asserted against us, any related patent or other intellectual property rights could adversely affect our ability to commercialize our products.
We may be subject to litigation over infringement claims regarding the products we manufacture or distribute or intend to manufacture or distribute. For example, on January 26, 2024, we were sued in the United States District Court for the District of Delaware by Advanced Accelerator Applications USA, Inc. and Advanced Accelerator Applications SA, each a Novartis entity, for patent infringement in response to the filing of our ANDA for PNT2003 and Paragraph IV certification, consistent with the process established by the Hatch-Waxman Act. This type of litigation can be costly and time consuming and could divert management’s attention and resources, generate significant expenses, damage payments (potentially including treble damages) or restrictions or prohibitions on our use of our technology, which could adversely affect our business, results of operations, financial condition and cash flows. In addition, if we are found to be infringing on proprietary rights of others, we may be required to develop non-infringing technology, obtain a license (which may not be available on reasonable terms, or at all), make substantial one-time or ongoing royalty payments, or cease making, using and/or selling the infringing products, any of which could have a material adverse effect on our business, results of operations, financial condition and cash flows.
We may be adversely affected by prevailing economic conditions and financial, business and other factors beyond our control.
Our ability to attract and retain customers, invest in and grow our business, maintain our desired levels of costs of goods sold and operating expenses and meet our financial obligations depends on our operating and financial performance, which, in turn, is subject to numerous factors, including the prevailing economic conditions and financial, business and other factors beyond our control, such as the rate of unemployment, the number of uninsured persons in the U.S. and inflationary pressures, including escalating energy prices. We cannot anticipate all the ways in which the current or future economic climate and financial market conditions could adversely impact our business. We are exposed to risks associated with reduced profitability and the potential financial instability of our customers, many of which may be adversely affected by volatile conditions in the financial markets. For example, unemployment and underemployment, and the resultant loss of insurance, may decrease the demand for healthcare services and pharmaceuticals. If fewer patients are seeking medical care because they do not have insurance coverage, our customers may experience reductions in revenues, profitability and/or cash flow that could lead them to modify, delay or cancel orders for our products. If customers are not successful in generating sufficient revenue or are precluded from securing financing, they may not be able to pay, or may delay payment of, accounts receivable that are owed to us. This, in turn, could adversely affect our financial condition and liquidity. To the extent prevailing economic conditions result in fewer procedures being performed, our business, results of operations, financial condition and cash flows could be adversely affected.
Similarly, we would expect our costs of goods sold and other operating expenses to change in the future in line with periodic inflationary changes in price levels. Because we intend to retain and continue to use our property and equipment, we believe that the incremental inflation related to the replacement costs of those items will not materially affect our operations. However, the rate of inflation affects our expenses, such as those for employee compensation, contract services, and transportation costs, which could increase our level of expenses and the rate at which we use our resources. While we generally believe that we will be able to offset the effect of price-level changes by adjusting our product prices and implementing operating efficiencies, any material unfavorable changes in price levels could have a material adverse effect on our financial condition, results of operations and cash flows.
Our business is subject to international economic, political and other risks that could negatively affect our results of operations or financial position.
For the year ended December 31, 2023, we derived approximately 2.6% of our revenues and sourced approximately 11.2% of our costs of goods sold outside of the United States. Accordingly, our business is subject to risks associated with doing business internationally, including:
Less stable political and economic environment and changes in a specific country’s or region’s political or economic conditions;
43

Table of Contents

Changes in trade policies, regulatory requirements and other barriers, including, for example, U.S. trade sanctions against Iran and those countries and entities doing business with Iran, which could adversely impact international isotope production and, indirectly, our global supply chain;
Potential global disruptions in air transport, which could adversely affect our international supply chains for radioisotopes and DEFINITY RT as well as international distribution channels for our commercial products;
Entering into, renewing or enforcing commercial agreements with international governments or provincial authorities or entities directly or indirectly owned or controlled by such governments or authorities, such as our Belgian, Australian and South African isotope suppliers, IRE, ANSTO and NTP, and our Chinese development and commercialization partner, Double-Crane;
International customers which are agencies or institutions owned or controlled by foreign governments;
Local business practices which may be in conflict with the U.S. Foreign Corrupt Practices Act and U.K. Bribery Act;
Currency fluctuations;
Unfavorable labor regulations;
Greater difficulties in relying on non-U.S. courts to enforce either local or U.S. laws, particularly with respect to intellectual property;
Greater potential for intellectual property piracy;
Greater difficulties in managing and staffing non-U.S. operations, including our EXINI operations in Sweden;
The need to ensure compliance with the numerous in-country and international regulatory and legal requirements applicable to our business in each of these jurisdictions and to maintain an effective compliance program to ensure compliance with these requirements, including in connection with the GDPR in the EU;
Changes in public attitudes about the perceived safety of nuclear facilities;
Civil unrest or other catastrophic events; and
Longer payment cycles of non-U.S. customers and difficulty collecting receivables in non-U.S. jurisdictions.
These factors are beyond our control. The realization of any of these or other risks associated with operating outside the United States could have a material adverse effect on our business, results of operations, financial condition and cash flows.
We face currency and other risks associated with international sales.
We generate revenue from export sales, as well as from operations conducted outside the United States. Operations outside the U.S. expose us to risks including fluctuations in currency values, trade restrictions, tariff and trade regulations, U.S. export controls, U.S. and non‑U.S. tax laws, shipping delays and economic and political instability. For example, violations of U.S. export controls, including those administered by the U.S. Treasury Department’s Office of Foreign Assets Control, could result in fines, other civil or criminal penalties and the suspension or loss of export privileges which could have a material adverse effect on our business, results of operations, financial conditions and cash flows.
Many of our customer relationships outside of the U.S. are, either directly or indirectly, with governmental entities, and we could be adversely affected by violations of the FCPA and similar worldwide anti-bribery laws outside the U.S.
The FCPA, the Bribery Act and similar worldwide anti-bribery laws in non-U.S. jurisdictions generally prohibit companies and their intermediaries from making improper payments to non-U.S. officials for the purpose of obtaining or retaining business.
The FCPA prohibits us from providing anything of value to foreign officials for the purposes of obtaining or retaining business or securing any improper business advantage. It also requires us to keep books and records that accurately and fairly reflect our transactions. Because of the predominance of government-sponsored healthcare systems around the world, many of our customer relationships outside of the U.S. are, either directly or indirectly, with governmental entities and are therefore subject to the FCPA and similar anti-bribery laws in non-U.S. jurisdictions. In addition, the provisions of the Bribery Act extend beyond bribery of foreign public officials and are more onerous than the FCPA in a number of other respects, including jurisdiction, non-exemption of facilitation payments and penalties.

Our policies mandate compliance with these anti-bribery laws. We operate in many parts of the world that have experienced governmental corruption to some degree, and in certain circumstances strict compliance with anti-bribery laws may conflict with local customs and practices. Despite our training and compliance programs, our internal control policies and procedures may not always protect us from reckless or criminal acts committed by our employees or agents. Violations of these laws, or allegations of those violations, could disrupt our business and result in a material adverse effect on our results of operations, financial condition and cash flows.
Our business depends on the continued effectiveness and availability of our information technology infrastructure, and failures of this infrastructure could harm our operations.
To remain competitive in our industry, we must employ information technologies to support manufacturing processes, quality processes, distribution, R&D and regulatory applications and that capture, manage and analyze large streams of data in compliance with applicable regulatory requirements. We rely extensively on technology, some of which is managed by third-party service providers, to allow the concurrent conduct of work sharing around the world. As with all information technology, our equipment and infrastructure age and become subject to increasing maintenance and repair and our systems generally are vulnerable to potential damage or interruptions from fires, natural disasters, power outages, blackouts, machinery breakdown, telecommunications failures and other unexpected events, as well as to break-ins, sabotage, increasingly sophisticated intentional acts of vandalism or cybersecurity threats which, due to the nature of such attacks, may remain undetected for a period of time. As these threats continue to evolve, we may be required to expend additional resources to enhance our information security measures or to investigate and remediate any information security vulnerabilities. Given the extensive reliance of our business on technology, any substantial disruption or resulting loss of data that is not avoided or corrected by our backup measures could harm our business, reputation, operations and financial condition.
A disruption in our computer networks, including those related to cybersecurity, could adversely affect our operations or financial position.
We believe that our cybersecurity program is designed to effectively mitigate the risks of material cybersecurity incidents. However, our management does not expect that our cybersecurity program will prevent or detect all occurrences of cybersecurity incidents, material or otherwise, and there is potential risk that certain cybersecurity breaches may go undetected for a period of time. The design of our cybersecurity program is based, in part, upon certain assumptions about the likelihood of future incidents, and there can be no assurance that any design will prevent or detect all cybersecurity breaches. Over time, certain aspects of cybersecurity programs may become inadequate because of changes in technology, sophistication of cybersecurity attacks, emerging threats or other conditions, or the degree of compliance with our policies and procedures may deteriorate.
We rely on our computer networks and systems, some of which are managed by third parties, to manage and store electronic information (including sensitive data such as confidential business information, personally identifiable data and personal health information), and to manage or support a variety of critical business processes and activities. We may face threats to our networks from unauthorized access, security breaches and other system disruptions. Despite our security measures, our infrastructure may be vulnerable to external or internal attacks. Any such security breach may compromise information stored on our networks and may result in significant data losses or theft of sensitive or proprietary information. A cybersecurity breach could hurt our reputation by adversely affecting the perception of customers and potential customers about the security of their orders and personal information, as well as the perception of our manufacturing partners of the security of their proprietary information. In addition, a cybersecurity attack could result in other negative consequences, including disruption of our internal operations, increased cybersecurity protection costs, lost revenue, regulatory actions or litigation. Any disruption of internal operations could also have a material adverse impact on our results of operations, financial condition and cash flows. To date, we have not experienced any known material cybersecurity attacks.
We may be limited in our ability to utilize, or may not be able to utilize, net operating loss carryforwards to reduce our future tax liability.
As of December 31, 2023, we had U.S. federal income tax loss carryforwards of $297.6 million, $157.9 million of which will expire between 2027 and 2037, $139.6 million of which can be carried forward indefinitely, and state income tax loss carryforwards of $12.5 million, tax-effected. We may be limited in our ability to use these tax loss carryforwards to reduce our future U.S. federal and state income tax liabilities if our future income is not sufficient to absorb the losses, or if we were to experience another “ownership change” as specified in Section 382 of the Internal Revenue Code including if we were to issue a certain amount of equity securities, certain of our stockholders were to sell shares of our common stock, or we were to enter into certain strategic transactions.
We are involved in various legal proceedings that are uncertain, costly and time-consuming and could have a material adverse impact on our business, financial condition and results of operations.
From time to time we are involved in legal proceedings and disputes and may be involved in litigation in the future. For example, on January 26, 2024, we were sued in the United States District Court for the District of Delaware by Advanced Accelerator Applications USA, Inc. and Advanced Accelerator Applications SA, each a Novartis entity, for patent infringement in response to the
45

Table of Contents

filing of our ANDA for PNT2003 and Paragraph IV certification, consistent with the process established by the Hatch-Waxman Act. These proceedings are complex and extended and occupy the resources of our management and employees.
Legal proceedings are also costly to prosecute and defend and may involve substantial awards or damages payable by us if not found in our favor. We may also be required to pay substantial amounts or grant certain rights on unfavorable terms in order to settle such proceedings.
Defending against or settling legal proceedings and any unfavorable legal decisions, settlements or orders could have a material adverse effect on our business, financial condition and results of operations and could cause the market value of our common stock to decline.
In particular, the pharmaceutical and medical device industries historically have generated substantial litigation concerning the manufacture, use and sale of products, and we expect this litigation activity to continue. As a result, we expect that patents related to our products will routinely be challenged, and our patents may not be upheld. In order to protect or enforce patent rights, we may initiate litigation against third parties. If we are not successful in defending an attack on our patents and maintaining exclusive rights to market one or more of our products still under patent protection, we could lose a significant portion of sales in a very short period. We may also become subject to infringement claims by third parties and may have to defend against charges that we violated patents or the proprietary rights of third parties. If we infringe the intellectual property rights of others, we could lose our right to develop, manufacture or sell products, or could be required to pay monetary damages or royalties to license proprietary rights from third parties.
In addition, in the U.S., it has become increasingly common for patent infringement actions to prompt claims that antitrust laws have been violated during the prosecution of the patent or during litigation involving the defense of that patent. Such claims by direct and indirect purchasers and other payors are typically filed as class actions. The relief sought may include treble damages and restitution claims. Similarly, antitrust claims may be brought by government entities or private parties following settlement of patent litigation, alleging that such settlements are anti-competitive and in violation of antitrust laws. In the U.S. and Europe, regulatory authorities have continued to challenge as anti-competitive so-called “reverse payment” settlements between branded and generic drug manufacturers. We may also be subject to other antitrust litigation involving competition claims unrelated to patent infringement and prosecution. A successful antitrust claim by a private party or government entity against us could have a material adverse effect on our business, financial condition and results of operations and could cause the market value of our common stock to decline.
Risks Related to our and our Strategic Partners’ Portfolios of Clinical Development Candidates
We may not, or may take longer to, realize the expected benefits and opportunities related to, the POINT License Agreements.
On December 20, 2022, we announced the closing of a set of strategic collaborations with an affiliate of POINT, in which we were granted a license to exclusive worldwide rights (excluding Japan, South Korea, China (including Hong Kong, Macau and Taiwan), Singapore and Indonesia) to co-develop and commercialize POINT’s PNT2002 and PNT2003 product candidates (the “POINT License Agreements”). The expected benefits and opportunities related to the POINT License Agreements may not be realized or may take longer to realize than expected due to, for example, challenges and uncertainties inherent in product research, development, manufacturing, regulatory approval, marketing and competition. In particular, activities under the POINT License Agreements may not result in viable products suitable for commercialization in a timely manner or at all, due to a variety of reasons, including any inability of the relevant parties to perform their commitments and obligations under the POINT License Agreements. The POINT License Agreements impose various development, regulatory filing, commercialization and other obligations on us, and require us to meet development timelines or to exercise commercially reasonable efforts to develop and commercialize licensed products. We, along with our counterparty in the POINT License Agreements, may not be able to meet expected or planned regulatory milestones and timelines due to a number of factors, including, with respect to PNT2003, potential litigation under the Hatch-Waxman Act that could impose a stay on FDA approval of up to 30 months. Even if the licensed products are suitable for commercialization in a timely manner, we may not achieve the expected revenues from the sale of such products, and our revenue, ability to achieve profitability and return on investment may be adversely affected.
With respect to PNT2002, on December 18, 2023, we announced positive topline results from SPLASH, the Phase 3 registrational trial for PNT2002. Although the topline results indicated that the SPLASH trial met its primary endpoint, at the time of our topline analysis, interim OS results were immature. We expect additional, follow-up data in 2024 prior to the potential submission of an NDA; however, we can give no assurance that, as additional data become available, such data will not be materially different from the topline data we previously published, or that such data will support an NDA filing, FDA approval, or successful commercialization of PNT2002.
In addition, we are dependent on POINT to develop commercial product capacity and manufacture clinical and commercial supply for both PNT2002 and PNT2003, as well as supply for our EAP for PNT2002.

Disagreements with the counterparty in the POINT License Agreements over proprietary rights, contract interpretation or the preferred course of product research, development or marketing, might cause delays in performance of the POINT License Agreements or termination of the POINT License Agreements, or might result in litigation or arbitration, which could be time-consuming and expensive.
In spite of our efforts, if we fail to comply with our obligations under the POINT License Agreements, the counterparty in the POINT License Agreements may conclude that we have materially breached and may terminate one or both of the POINT License Agreements, in which event we may lose our rights to develop and market PNT2002 and PNT2003 or incur liability for damages.
Any of the foregoing risks could materially and adversely affect our business, results of operations and prospects and the trading price of our common stock.
We may not, or may take longer to, realize the expected benefits and opportunities related to, the Cerveau Acquisition.
On February 6, 2023, we announced that we acquired Cerveau. Cerveau holds the rights under a license agreement to develop and commercialize MK-6240, an investigational second-generation F 18-labeled PET imaging agent that targets Tau tangles in Alzheimer’s disease. MK-6240 is currently being used in more than 90 active clinical trials for several Alzheimer’s disease therapeutic candidates being developed. While we believe that MK-6240, as a Tau imaging agent, has the potential to play an important role in patient staging, selection, and monitoring for future treatments and could be a surrogate endpoint for treatment efficacy, we can give no assurance that we will be successful with continued development, regulatory approval and commercialization of the product candidate or that disagreements with the counterparty to our license agreement for MK-6240 or the Selling Stockholders will not arise over proprietary rights, contract interpretation or the preferred course of product research, development or marketing that might cause delays or termination of the license agreement, or might result in litigation or arbitration, which could be time-consuming and expensive.
The process of developing new drugs and obtaining regulatory approval is complex, time-consuming and costly, and the outcome is not certain.
We currently have clinical development programs in the U.S., including those related to PNT2002, PNT2003, MK-6240 and LNTH-1363S, and are exploring additional lifecycle management opportunities for some of our current products, including PYLARIFY. We also have a number of strategic partnerships relating to obtaining additional indications for existing commercial products or regulatory approval for clinical development candidates. To obtain regulatory approval for these products in the indications being pursued, we must conduct extensive human tests, which are referred to as clinical trials, as well as meet other rigorous regulatory requirements, as further described in Part I, Item 1. “Business—Regulatory Matters.” Satisfaction of all regulatory requirements typically takes many years and requires the expenditure of substantial resources. A number of other factors may cause significant delays in the completion of our clinical trials, including unexpected delays in the initiation of clinical sites, slower than projected enrollment, competition with ongoing clinical trials and scheduling conflicts with participating clinicians, regulatory requirements, limits on manufacturing capacity and failure of an investigational product to meet required standards for administration to humans. In addition, it may take longer than we project to achieve study endpoints and complete data analysis for a clinical trial or we may decide to slow down the enrollment in a trial in order to conserve financial resources or for other reasons.
Our products in development are also subject to the risks of failure inherent in drug development, drug testing and regulatory approval. The results of preliminary studies do not necessarily predict clinical success, and larger and later stage clinical trials may not produce the same results as earlier stage trials. Sometimes, products that have shown promising results in early clinical trials have subsequently suffered significant setbacks in later clinical trials. Products in later stage clinical trials may fail to show desired safety and efficacy traits, despite having progressed through initial clinical testing. In addition, the data collected from clinical trials of our products in development may not be sufficient to support regulatory approval, or regulators could interpret the data differently and less favorably than we do. Further, the design of a clinical trial can determine whether its results will support approval of a product, and flaws in the design of a clinical trial may not become apparent until the clinical trial is well advanced. Clinical trials of potential products often reveal that it is not practical or feasible to continue development efforts. Regulatory authorities may require us or our partners to conduct additional clinical testing, in which case we would have to expend additional time and resources. Depending on the regulatory pathway selected for drug approval, such as by filing an ANDA or Section 505(b)(2) NDA that requires sending notice to the innovator of a drug, regulatory approval may also be delayed by litigation brought under the Hatch-Waxman Act. For example, on January 26, 2024, we were sued in the United States District Court for the District of Delaware by Advanced Accelerator Applications USA, Inc. and Advanced Accelerator Applications SA, each a Novartis entity, for patent infringement in response to the filing of our ANDA for PNT2003 and Paragraph IV certification, consistent with the process established by the Hatch-Waxman Act. The approval process may also be delayed by changes in government regulation, future legislation or administrative action or changes in regulatory policy that occur prior to or during regulatory review. The failure to provide clinical and preclinical data that are adequate to demonstrate to the satisfaction of the regulatory authorities that our products in development are safe and effective for their proposed use will delay or preclude approval and will prevent us from marketing those products.

Table of Contents

We are not permitted to market our products in development in the U.S. or other countries until we have received requisite regulatory approvals. For example, securing FDA approval for a new drug requires the submission of an NDA to the FDA for our products in development. The NDA must include extensive nonclinical and clinical data and supporting information to establish the product’s safety and effectiveness for each indication. The NDA must also include significant information regarding the chemistry, manufacturing and controls for the product. The FDA review process can take many years to complete, and approval is never guaranteed. If a product is approved, the FDA may limit the indications for which the product may be marketed, require extensive warnings on the product labeling, impose restricted distribution programs, require expedited reporting of certain adverse events, or require costly ongoing requirements for post-marketing clinical trials and surveillance or other risk management measures to monitor the safety or efficacy of the product. In some instances, products in development may also be approved by filing an ANDA or Section 505(b)(2) NDA with the FDA (as further described in Part I, Item 1. “Business—Regulatory Matters—Hatch-Waxman Act.”); provided, however, that seeking regulatory approval under such pathways may subject the product candidate to delays caused by litigation brought by an innovator of similar drugs under the Hatch-Waxman Act, as is the case with our ANDA application and Paragraph IV certification for PNT2003. Markets outside of the U.S. also have requirements for approval of products with which we must comply prior to marketing. Obtaining regulatory approval for marketing of a product in one country does not ensure we will be able to obtain regulatory approval in other countries, but a failure or delay in obtaining regulatory approval in one country may have a negative effect on the regulatory process in other countries. Also, any regulatory approval of any of our products in development, once obtained, may be withdrawn. Approvals might not be granted on a timely basis, if at all.
We can give no assurance that GE Healthcare will be successful with the further clinical development of flurpiridaz.
In May 2015, we announced complete results from the first of two planned Phase 3 clinical trials for flurpiridaz. Although the development candidate appeared to be well-tolerated from a safety perspective and outperformed SPECT in a highly statistically significant manner in the co-primary endpoint of sensitivity and in the secondary endpoints of image quality and diagnostic certainty, flurpiridaz did not meet its other co-primary endpoint of non-inferiority for identifying subjects without disease. In April 2017, we entered into the License Agreement with GE Healthcare for the continued Phase 3 development and worldwide commercialization of flurpiridaz. Under the License Agreement, GE Healthcare agreed, among other things, to complete the worldwide development of flurpiridaz by conducting a second Phase 3 trial and pursue worldwide regulatory approvals. In September 2022, we announced with GE Healthcare that the second Phase 3 clinical trial had met its co-primary endpoints of exceeding a 60% threshold for both sensitivity and specificity for detecting CAD. The findings, shared at an American Society of Nuclear Cardiology conference, also demonstrated that cardiac PET imaging with flurpiridaz had higher diagnostic efficacy and image quality in patients with suspected CAD, compared with SPECT MPI, the predominant procedure currently used in nuclear cardiology. Notwithstanding these findings, we cannot assure that any of the data generated in either our or GE Healthcare’s sponsored Phase 3 study will be sufficient to support an NDA approval or that flurpiridaz will ever be approved as a PET MPI imaging agent by the FDA. While GE Healthcare recently announced that it had filed an NDA with the FDA for flurpiridaz, any failure or significant delay in receiving regulatory approval for the sale of flurpiridaz may harm our business and delay or prevent us from being able to generate additional future royalty revenue from product sales.
Even if clinical development candidates receive regulatory approval, we can give no assurance that they can be successfully commercialized.
Even if our clinical development candidates proceed through their clinical trials and ultimately receive regulatory approval, there is no guarantee that an approved product can be manufactured in commercial quantities at a reasonable cost or that such a product will be successfully marketed or distributed. For example, the manufacturing, marketing and distribution of a radiopharmaceutical like flurpiridaz and MK-6240 will require the creation of a field-based network of specialized PET manufacturing facilities, or PMFs, with radioisotope-producing cyclotrons, similar to what we created for PYLARIFY, and will need to be manufactured and distributed rapidly to end-users.
In addition, obtaining adequate coding, coverage and payment at appropriate payment levels for any clinical development candidate will be critical, including not only coverage from Medicare, Medicaid, and other government payors, but also from private payors. We can give no assurance, even if a clinical development candidate were to obtain regulatory approval, that adequate coding, coverage and payment could be secured to allow the approved products to become successfully commercialized.
We have been and expect to continue to be dependent on partners for the development of certain product candidates, which expose us to the risk of reliance on these partners.
In connection with our ongoing development activities, we currently depend, and expect to continue to depend, on numerous collaborators. For example, in addition to our collaboration with Curium on PYLCLARI in Europe, GE Healthcare on flurpiridaz and POINT on PNT2002 and PNT2003, we have other collaborations to develop and commercialize products. In addition, certain clinical trials for our product candidates may be conducted by government-sponsored agencies, and consequently will be dependent on governmental participation and funding. These arrangements expose us to the same considerations we face when contracting with third parties for our own trials.
48

Table of Contents

If any of our collaborators breach or terminate its agreement with us or otherwise fail to conduct successfully and in a timely manner the collaborative activities for which they are responsible, the preclinical or clinical development or commercialization of the affected product candidate or research program could be delayed or terminated. We generally do not control the amount and timing of resources that our collaborators devote to our programs or product candidates. We also do not know whether current or future collaboration partners, if any, might pursue alternative technologies or develop alternative products either on their own or in collaboration with others, including our competitors, as a means for developing treatments for the diseases or conditions targeted by our collaborative arrangements. Our collaborators are also subject to similar development, regulatory, manufacturing, cyber-security and competitive risks as us, which may further impede their ability to successfully perform the collaborative activities for which they are responsible. Setbacks of these types to our collaborators could have a material adverse effect on our business, results of operations and financial condition.
We depend on licenses from third parties for our rights to develop and commercialize certain product candidates. If we fail to achieve milestone requirements or to satisfy other conditions, we may lose those rights under those license agreements, and our business, results of operations and financial condition could be adversely affected.
Many of our products or product candidates incorporate rights licensed by third parties -- for example, we license patent rights on PYLARIFY, PNT2002, PNT2003, MK-6240, LNTH-1363S and NM-01. We could lose the rights to develop or commercialize these products and product candidates if the related license agreement is terminated due to a breach by us or otherwise. In addition, we are required to make substantial cash payments, achieve milestones and satisfy other conditions, including filing for and obtaining marketing approvals and introducing products, sometimes in accordance with established timelines, to maintain rights under our license agreements. Due to the nature of these agreements and the uncertainties of development, we may not be able to achieve milestones or satisfy conditions to which we have contractually committed, and as a result may be unable to maintain our rights under these licenses. If we do not comply with our license agreements, the licensors may terminate them, which could result in our losing our rights to, and therefore being unable to commercialize, related products. This loss could have a material adverse effect on our business, results of operations and financial condition.
Risks Related to Our Capital Structure
The conditional conversion feature of the 2.625% Convertible Senior Notes due 2027, if triggered, may adversely affect our financial condition and operating results.
On December 8, 2022, we issued $575.0 million in aggregate principal amount of 2.625% Convertible Senior Notes due 2027 (the “Notes”), which included $75.0 million in aggregate principal amount of Notes sold pursuant to the full exercise of the initial purchasers’ option to purchase additional Notes. The Notes were issued under an indenture, dated as of December 8, 2022 (the “Indenture”), among Holdings, LMI, and U.S. Bank Trust Company, National Association (“U.S. Bank”), as Trustee. Prior to the close of business on the business day immediately preceding September 15, 2027, the Notes may be converted at the option of the holders upon occurrence of specified events and during certain periods, and thereafter until the close of business on the business day immediately preceding the maturity date, the Notes may be converted at any time. If one or more holders elect to convert their Notes, we would be required to settle any converted principal amount of such Notes through the payment of cash and by paying or delivering, at our election, cash, shares of our common stock, or a combination of cash and shares, with respect to the remainder of our conversion obligation in excess of the aggregate principal amount of the Notes being converted, which could adversely affect our liquidity. In addition, even if holders do not elect to convert their Notes, we could be required under applicable accounting rules to reclassify all or a portion of the outstanding principal of the Notes as a current rather than long-term liability, which would result in a material reduction of our net working capital.
The issuance or sale of shares of our common stock, or rights to acquire shares of our common stock, could depress the trading price of our common stock.
We may conduct future offerings of our common stock, preferred stock or other securities that are convertible into or exercisable for our common stock to finance our operations or fund acquisitions, or for other purposes. In addition, we expect to continue to grant equity awards to directors, officers and employees under our equity incentive plans. If we issue additional shares of our common stock or rights to acquire shares of our common stock, if any of our existing stockholders sells a substantial amount of our common stock, or if the market perceives that such issuances or sales may occur, then the trading price of our common stock may significantly decrease. In addition, our issuance of additional shares of common stock will dilute the ownership interests of our existing common stockholders.
Repurchases by us of our common stock may affect the value of our common stock.
In December 2022, our Board authorized the repurchase of up to $150.0 million in aggregate amount of our common stock under certain circumstances. We used approximately $75.0 million of the net proceeds from the Notes to repurchase shares of our common stock from purchasers of Notes in privately negotiated transactions effected with or through one of the initial purchasers or its affiliate. The purchase price per share of the common stock repurchased in such transactions was equal to the closing sale price per share of our
49

Table of Contents

common stock on December 5, 2022, which was $56.01 per share. Following this initial repurchase, we may from time to time repurchase additional shares of our common stock. Such repurchases could increase, or prevent a decrease in, the market price of our common stock.
We have indebtedness which may limit our financial and operating activities and may adversely affect our ability to incur additional debt to fund future needs.
As of December 31, 2023, we had approximately $575.0 million of total principal indebtedness remaining under the Notes and availability of $350.0 million under our five-year 2022 Revolving Facility. Our indebtedness and any future indebtedness we incur could:
Require us to dedicate a substantial portion of cash flow from operations to the payment of interest on and principal of our indebtedness, thereby reducing the funds available for other purposes, including for working capital, capital expenditures and acquisitions;
Make it more difficult for us to satisfy and comply with our obligations with respect to our outstanding indebtedness, namely the payment of interest and principal;
Make it more difficult to refinance the outstanding indebtedness;
Subject us to increased sensitivity to interest rate increases;
Make us more vulnerable to economic downturns, adverse industry or company conditions or catastrophic external events;
Limit our ability to withstand competitive pressures;
Reduce our flexibility in planning for or responding to changing business, industry and economic conditions; and
Place us at a competitive disadvantage to competitors that have relatively less debt than we have.
In addition, our level of indebtedness could limit our ability to obtain additional financing on acceptable terms, or at all, for working capital, capital expenditures and general corporate purposes. Our liquidity needs could vary significantly and may be affected by general economic conditions, industry trends, performance and many other factors outside our control.
We may not be able to generate sufficient cash flow to meet our debt service obligations.
Our ability to generate sufficient cash flow from operations to make scheduled payments on our debt obligations will depend on our future financial performance, which will be affected by a range of economic, competitive and business factors, many of which are outside of our control. If we do not generate sufficient cash flow from operations to satisfy our debt obligations, including interest and principal payments, our credit ratings could be downgraded, and we may have to undertake alternative financing plans, such as refinancing or restructuring our debt, selling assets, entering into additional corporate collaborations or licensing arrangements for one or more of our products in development, reducing or delaying capital investments or seeking to raise additional capital. We cannot assure you that any refinancing would be possible, that any assets could be sold, licensed or partnered, or, if sold, licensed or partnered, of the timing of the transactions and the amount of proceeds realized from those transactions, that additional financing could be obtained on acceptable terms, if at all, or that additional financing would be permitted under the terms of our various debt instruments then in effect. Furthermore, our ability to refinance would depend upon the condition of the financial and credit markets. Our inability to generate sufficient cash flow to satisfy our debt obligations, or to refinance our obligations on commercially reasonable terms or on a timely basis, would have an adverse effect on our business, results of operations and financial condition.
Despite our indebtedness, we may incur more debt, which could exacerbate the risks described above.
We and our subsidiaries may be able to incur substantial additional indebtedness in the future subject to the limitations contained in the agreements governing our debt, including the 2022 Revolving Facility. Although these agreements restrict us and our restricted subsidiaries from incurring additional indebtedness, these restrictions are subject to important exceptions and qualifications. For example, we are generally permitted to incur certain indebtedness, including indebtedness arising in the ordinary course of business, indebtedness among restricted subsidiaries and us and indebtedness relating to hedging obligations. If we or our subsidiaries incur additional debt, the risks that we and they now face as a result of our leverage could intensify. In addition, the 2022 Revolving Facility will not prevent us from incurring obligations that do not constitute indebtedness under that agreement.
Our 2022 Revolving Facility contains restrictions that will limit our flexibility in operating our business.
Our 2022 Revolving Facility contains various covenants that limit our ability to engage in specified types of transactions. These covenants limit our and our restricted subsidiaries’ ability to, among other things:
Maintain net leverage above certain specified levels;
50

Table of Contents

Maintain interest coverage below certain specified levels;
Incur additional debt;
Pay dividends or make other distributions;
Redeem stock;
Issue stock of subsidiaries;
Make certain investments;
Create liens;
Enter into transactions with affiliates; and
Merge, consolidate or transfer all or substantially all of our assets.
A breach of any of these covenants could result in a default under the 2022 Revolving Facility. We may also be unable to take advantage of business opportunities that arise because of the limitations imposed on us by the restrictive covenants under our indebtedness.
U.S. credit markets may impact our ability to obtain financing or increase the cost of future financing, including interest rate fluctuations based on macroeconomic conditions that are beyond our control.
During periods of volatility and disruption in the U.S., European, or global credit markets, obtaining additional or replacement financing may be more difficult and the cost of issuing new debt or replacing or repaying our 2022 Facility could be higher than under our current 2022 Facility. Higher cost of new debt may limit our ability to have cash on hand for working capital, capital expenditures and acquisitions on terms that are acceptable to us. Additionally, our 2022 Facility has variable interest rates. By its nature, a variable interest rate will move up or down based on changes in the economy and other factors, all of which are beyond our control. If interest rates increase, our interest expense could increase, affecting earnings and reducing cash flows available for working capital, capital expenditures and acquisitions.
Our stock price could fluctuate significantly, which could cause the value of your investment to decline, and you may not be able to resell your shares at or above your purchase price.
Securities markets worldwide have experienced, and may continue to experience, significant price and volume fluctuations. This market volatility, as well as general economic, market or political conditions, could reduce the market price of our common stock regardless of our operating performance. The high and low closing sales prices of our common stock during the twelve months ended December 31, 2023 were $99.65 and $47.76, respectively. The trading price of our common stock is likely to be volatile and subject to wide price fluctuations in response to various factors, including:
Market conditions in the broader stock market;
Actual or anticipated fluctuations in our quarterly financial and operating results;
Issuance of new or changed securities analysts’ reports or recommendations;
Investor perceptions of us and the pharmaceutical and medical device industries;
Sales, or anticipated sales, of large blocks of our stock;
Acquisitions or introductions of new products or services by us or our competitors;
Positive or negative results from our clinical development programs;
Additions or departures of key personnel;
Regulatory or political developments;
Loss of intellectual property protections;
Litigation and governmental investigations;
Geopolitical events; and
Changing economic conditions.

Table of Contents

These and other factors may cause the market price and demand for our common stock to fluctuate substantially, which may limit or prevent investors from readily selling their shares of common stock and may otherwise negatively affect the liquidity of our common stock. In addition, in the past, when the market price of a stock has been volatile, holders of that stock have sometimes instituted securities class action litigation against the company that issued the stock. If any of our stockholders brought a lawsuit against us, we could incur substantial costs defending the lawsuit. Such a lawsuit could also divert the time and attention of our management from our business, which could significantly harm our profitability and reputation.
If securities or industry analysts do not publish research or reports about our business, if they adversely change their recommendations regarding our stock, or if our results of operations do not meet their expectations, our stock price and trading volume could decline.
The trading market for our common stock will be influenced by the research and reports that industry or securities analysts publish about us or our business. If one or more of these analysts ceases coverage of our company or fails to publish reports on us regularly, we could lose visibility in the financial markets, which in turn could cause our stock price or trading volume to decline. Moreover, if one or more of the analysts who cover us downgrades our stock, or if our results of operations do not meet their expectations, our stock price could also decline.
We do not anticipate paying any cash dividends for the foreseeable future, and accordingly, stockholders must rely on stock appreciation for any return on their investment.
We have never declared or paid cash dividends on our capital stock. We currently intend to retain our future earnings, if any, for the foreseeable future, to repay indebtedness and to fund the development and growth of our business. We do not intend to pay any dividends to holders of our common stock and the agreements governing our senior secured credit facilities limit our ability to pay dividends. As a result, capital appreciation in the price of our common stock, if any, will be your only source of gain on an investment in our common stock.
Anti-takeover provisions in our charter documents and Delaware law and certain provisions in the Notes and Indenture may make an acquisition of us more difficult.
Our amended and restated certificate of incorporation and bylaws, as amended and restated, contain provisions that delay, defer or discourage transactions involving an actual or potential change in control of us or change in our management. These provisions may also discourage bids for our common stock at a premium over market price or adversely affect the market price of, and the voting and other rights of the holders of, our common stock. These provisions could also discourage proxy contests and make it more difficult for stockholders to elect directors other than the candidates nominated by our Board. In addition, we are incorporated in Delaware and subject to the provisions of Section 203 of the Delaware General Corporation Law, which may prohibit large stockholders from consummating a merger with, or acquisition of, us. These provisions may deter an acquisition of us that might otherwise be attractive to stockholders.
Certain provisions in the Notes and the Indenture could make it more difficult or more expensive for a third party to acquire us. For example, if a takeover would constitute a fundamental change, holders of the Notes will have the right to require us to repurchase their Notes in cash. In addition, if a takeover constitutes a make-whole fundamental change, we may be required to increase the conversion rate for holders who convert their Notes in connection with such takeover. In either case, and in other cases, our obligations under the Notes and the Indenture could increase the cost of acquiring us or otherwise discourage a third party from acquiring us or removing incumbent management, including in a transaction that holders of our common stock may view as favorable.
Item 1B. Unresolved Staff Comments
None.
Item 1C. Cybersecurity
Risk management and strategy
With respect to cybersecurity risks, we have invested and continually invest in new cybersecurity services, technologies, and capabilities. On an ongoing basis we provide our employees with comprehensive cybersecurity awareness training around phishing, malware and other cybersecurity risks, all in a manner reasonably intended to educate employees to safely avoid cyber attacks and mitigate the risk of employee related security breaches. In support of our cybersecurity program, our systems and services undergo regular reviews by management to determine if any insufficiencies in cybersecurity exist.
If an incident is detected, the Cybersecurity team follows the incident response policy to investigate, review and determine the potential impacts of such an incident. If the Cybersecurity team determines that an incident could reasonably be expected to have an impact on the financial condition or operations of the Company, it escalates the incident to the crisis management team, which includes executive management. The crisis management team further evaluates the potential impact and materiality of an event and the

appropriate response required. The crisis management team coordinates the appropriate response effort and communicates, as applicable, to the Audit Committee. To the extent that Cybersecurity incident is determined to be material, the appropriate public disclosures are made.
We monitor material risks from cybersecurity threats relating to potential compromises of sensitive information at our third-party business partners where relevant and reevaluate these risks periodically. We also perform third-party cybersecurity audits at least annually and conduct third-party security reviews and testing of our network, processes and systems periodically.
Impact of cybersecurity risks on business strategy, results of operations or financial condition
We rely on our computer networks and systems, some of which are managed by third-parties, to manage and store electronic information (including sensitive data such as confidential business information, personally identifiable data and personal health information), and to manage or support a variety of critical business processes and activities. We may face threats to our networks from unauthorized access, security breaches and other system disruptions. Despite our security measures, our infrastructure may be vulnerable to external or internal attacks. Any such security breach may compromise information stored on our networks and may result in significant data losses or theft of sensitive or proprietary information. A cybersecurity breach could hurt our reputation by adversely affecting the perception of customers and potential customers about the security of their orders and personal information, as well as the perception of our manufacturing partners of the security of their proprietary information. In addition, a cybersecurity attack could result in other negative consequences, including disruption of our internal operations, increased cybersecurity protection costs, lost revenue, regulatory actions or litigation. Any disruption of internal operations could also have a material adverse impact on our results of operations, financial condition and cash flows.
As of the date of this report, we have not experienced any known cybersecurity incidents, or a series of related incidents, that have materially affected or are reasonably likely to affect us, including our business strategy, results of operations or financial condition. For an additional description of these cybersecurity risks and potential related impacts on us, see “Risk Factors” in Part I, Item 1A of this Annual Report on Form 10-K.
Governance
Our Board actively oversees our corporate strategy and enterprise risk management (“ERM”) programs, including those relating to cybersecurity and data privacy risks.
Our Audit Committee and Nominating and Corporate Governance Committee are primarily responsible for, among other things, overseeing our compliance and ERM programs, information technology systems, and our processes and data, including cybersecurity and data privacy. These responsibilities include reviewing and discussing with management our policies and processes relating to risk assessment and risk management. Cybersecurity and data privacy are regular topics on the Audit Committee’s agenda and management reviews at least quarterly the results of cybersecurity monitoring and discusses performance metrics, any incidents identified and potential recommended modifications to our technology, organization training, awareness and governance with our Audit Committee. A summary of these results are also reported by the Audit Committee to the Board at least annually.
Management, including our Chief Information Officer (“CIO”), who has over 25 years of experience serving primarily in the life science industry and is a recognized industry leader, is responsible for monitoring and assessing cybersecurity risks. Management reviews and determines the effectiveness of both internal and third-party leveraged expertise to ensure we have the appropriate knowledge base for risk coverage.

Overview
Our Business
We are the leading radiopharmaceutical-focused company, delivering life-changing science to enable clinicians to Find, Fight and Follow disease to deliver better patient outcomes. We classify our products in three categories: Radiopharmaceutical Oncology, Precision Diagnostics, and Strategic Partnerships and Other Revenue. Our Radiopharmaceutical Oncology diagnostics and therapeutics help healthcare professionals (“HCPs”) Find, Fight and Follow cancer, with a focus on prostate cancer. Our leading Precision Diagnostic products assist HCPs to Find and Follow diseases, with a focus in cardiology. Our Strategic Partnerships focus on enabling precision medicine through the use of biomarkers, digital solutions and pharma solutions platforms.
Our commercial products are used by cardiologists, internal medicine physicians, nuclear medicine physicians, oncologists, radiologists, sonographers, technologists, and urologists working in a variety of clinical settings. We believe that our diagnostic products provide improved information that enables HCPs to better detect and characterize, or rule out, disease, with the potential to achieve better patient outcomes, reduce patient risk and limit overall costs throughout the healthcare system.
We produce and market our products throughout the United States (the “U.S.”), selling primarily to hospitals, independent diagnostic testing facilities, and radiopharmacies. We sell our products outside the U.S. through a combination of direct distribution in Canada and third party distribution relationships in Europe, Canada, Australia, Asia-Pacific, Central America and South America.
Our executive offices are located in Bedford, Massachusetts, with additional offices in North Billerica, Massachusetts; Somerset, New Jersey; Montreal, Canada; and Lund, Sweden.
Recent Developments
CEO Succession Plan
On January 23, 2024, we announced that, effective March 1, 2024, Brian Markison, our current Chair of the Board, will become our Chief Executive Officer, and Mary Anne Heino, our current Chief Executive Officer, will retire and become the Chair of the Board. As part of this leadership transition, Mr. Markison assumed the role of Executive Chair of the Board as of January 23, 2024 until the effectiveness of his Chief Executive Officer appointment in March, and Board Member Julie McHugh became Lead Independent Director.
Strategic Agreements with Perspective Therapeutics
On January 9, 2024, we announced that we entered into multiple strategic agreements with Perspective, a radiopharmaceutical company that is pursuing advanced treatment applications for cancers throughout the body. Under the agreements, we obtained an option to exclusively license Perspective’s Pb212-VMT- ⍺-NET, a clinical stage alpha therapy in development for the treatment of neuroendocrine tumors, and an option to co-develop certain early-stage therapeutic candidates targeting prostate cancer using Perspective’s innovative platform technology, for an aggregate upfront payment of $28 million in cash. We also agreed to purchase up to 19.9% of Perspective’s outstanding shares of common stock for up to approximately $33 million, subject to Perspective’s completion of a qualified third-party financing transaction and certain other closing conditions. In addition, Perspective agreed to acquire the assets and associated lease of our radiopharmaceutical manufacturing facility in Somerset, New Jersey, subject to customary closing conditions, including regulatory approval.
On January 22, 2024, following the satisfaction of applicable closing conditions, our subsidiary, Lantheus Alpha, purchased 56,342,355 shares of Perspective’s common stock at a purchase price of $0.37 per share in a private placement transaction. The total consideration for the purchase was approximately $20.8 million in cash, which resulted in Lantheus Alpha holding approximately

10.74% of Perspective’s common stock as of the purchase date and retaining the right to purchase additional shares to bring its ownership up to an aggregate of 19.9%.
Exclusive License for PNT2002 and PNT2003
On December 20, 2022, we announced the closing of a set of strategic collaborations with POINT Biopharma Global Inc. (“POINT”), in which we were granted a license to exclusive worldwide rights (excluding Japan, South Korea, China (including Hong Kong, Macau, and Taiwan), Singapore, and Indonesia) to co-develop and commercialize POINT’s PNT2002 and PNT2003 product candidates.
On December 27, 2023, Eli Lilly announced the completion of its acquisition of POINT. The acquisition is no expected to impact the status of the PNT2002 License Agreement, the PNT2003 License Agreement, or the work being performed in connection with those agreements and our collaboration with POINT.
PNT2002
With respect to PNT2002, POINT is generally responsible for funding and development activities required for FDA approval, including generating all clinical and nonclinical data, analysis and other information, and we are responsible for preparing for and seeking regulatory approval for PNT2002, as well as performing and funding all future development and commercialization following such approval. POINT will be responsible for all manufacturing of PNT2002, subject to certain exceptions described in the license and collaboration agreement between Lantheus Two and POINT, dated November 11, 2022 (the “PNT2002 License Agreement”).
In April 2023, we announced with POINT that the FDA had granted Fast Track designation for PNT2002. Fast Track is a process designed to facilitate the development and expedite the review of drugs to treat serious conditions and address unmet needs.
On December 18, 2023, we announced positive topline results from SPLASH, the Phase 3 registrational trial for PNT2002. SPLASH was designed to evaluate the efficacy and safety of PNT2002 in patients with mCRPC who have progressed following treatment with an androgen receptor pathway inhibitor (“ARPI”). The SPLASH trial met its primary endpoint, demonstrating a median radiographic progression-free survival (rPFS) per blinded independent central review of 9.5 months for patients treated with PNT2002, compared to 6.0 months for patients treated with ARPI in the control arm, a statistically significant 29% reduction in the risk of radiographic progression or death (hazard ratio (“HR”) 0.71; p=0.0088). At the time of the analysis, interim overall survival (OS) results were immature (46% of protocol-specified target OS events reached), and the HR was 1.11. We expect more mature overall survival data in 2024 prior to the potential submission of a New Drug Application (“NDA”).
PNT2002 demonstrated a favorable safety profile with grade ≥3 treatment-emergent adverse events (TEAEs) per Common Terminology Criteria for Adverse Events, serious TEAEs, and TEAEs leading to discontinuation occurring at lower rates in the PNT2002 arm than in the control arm (30.1%, 17.1%, and 1.9% versus 36.9%, 23.1%, and 6.2%, respectively).
The open-label study randomized 412 patients with PSMA-expressing mCRPC who had progressed on ARPI therapy and either refused or were not eligible for chemotherapy, in a 2:1 randomization ratio. At the time of the analysis, 84.6% of patients who experienced progressive disease in the control arm subsequently crossed over to receive PNT2002. SPLASH was conducted across the U.S., Canada, Europe, and the United Kingdom. Eighty percent of SPLASH patients resided in North America and approximately ten percent of all participants were Black or African American.
During 2023, we worked on establishing an EAP, for PNT2002. EAPs, which are also referred to as compassionate use programs, provide a potential pathway for patients with serious or life-threatening conditions to gain access to an investigational drug for treatment outside of a clinical trial. We expect to enroll the first patient in the EAP for PNT2002 during the first quarter of 2024.
PNT2003
With respect to PNT2003, POINT is responsible for curating all data, analysis and other information necessary for regulatory approval, and supporting us in the preparation of regulatory filings. We are responsible for preparing for and seeking regulatory approval of all such applications, as well as performing and funding all future development and commercialization following such approval. POINT will be responsible for all manufacturing of PNT2003, subject to certain exceptions described in the license and collaboration agreement between Lantheus Three and POINT, dated November 11, 2022 (the “PNT2003 License Agreement”). On January 11, 2024, we announced that our ANDA for PNT2003 had been accepted for filing by the FDA. Based on the most recent update to the FDA’s online paragraph IV database listings, we believe we are the first applicant to have filed a substantially complete ANDA for Lutetium Lu 177 Dotatate containing a Paragraph IV certification under the provisions of the Hatch-Waxman Act. As the first applicant, we believe we will be eligible for 180 days of generic marketing exclusivity in the U.S. On January 26, 2024, we were sued in the District Court for the District of Delaware by Advanced Accelerator Applications USA, Inc. and Advanced Accelerator Applications SA, each a Novartis entity, for patent infringement in response to the Company’s ANDA filing and Paragraph IV
59

Table of Contents

certification, consistent with the process established by the Hatch-Waxman Act. Under the terms of the Hatch-Waxman Act, FDA approval of our ANDA filing could be subject to a stay of up to 30-months. If our filing is stayed for the full 30-month period and we are successful in obtaining FDA approval, we would expect to launch PNT2003 in 2026, although no assurance of that approval or timing can be assured.
For more information, see Note 21, “Acquisition of Assets” in our consolidated financial statements included herein.
Acquisition of Cerveau Technologies, Inc.
On February 6, 2023, we announced that we acquired Cerveau. Cerveau holds the rights under a license agreement to develop and commercialize MK-6240, an investigational second-generation F 18-labeled PET imaging agent that targets Tau tangles in Alzheimer’s disease. Under the terms of the agreement, we paid the Selling Stockholders an upfront payment of $35.0 million in February 2023 and an additional $10.0 million in May 2023 upon the successful completion of a technology transfer. The Selling Stockholders are also eligible to receive additional development and commercial milestone payments. Additionally, we will pay double-digit royalty payments for research revenue and commercial sales. Research revenue is derived from existing partnerships with pharmaceutical companies that use MK-6240 in clinical trials and includes milestone and dose-related payments. Pursuant to the terms of the stock purchase agreement for Cerveau, certain members of the Selling Stockholders will also provide transition and clinical development services for a prescribed time following the closing of the transaction.
In September 2023, MK-6240 was granted Fast Track designation by the FDA.
For more information, see Note 21, “Acquisition of Assets” in our consolidated financial statements included herein.
Sale of RELISTOR Licensed Intangible Asset Associated with Net Sales Royalties
On August 2, 2023, we sold the right to our RELISTOR net sales royalties, which is classified as a licensed intangible asset (“RELISTOR royalty asset”), under our license agreement with Bausch; we retained the rights to future sales-based milestone payments. We received an initial payment of approximately $98.0 million in connection with the sale and we have the right to receive an additional payment from the buyer of $5.0 million if worldwide net sales of RELISTOR in 2025 exceed a specified threshold. The additional payment would be recognized upon achievement of the specified threshold. Decreases of $63.6 million of license assets and $17.5 million of associated accumulated amortization, as well as a gain of $51.8 million were recorded as a result of the sale. During the fourth quarter of 2023, the Company earned a $15 million sales-based milestone payment.
For more information, see Note 10, “Intangibles, Net and Goodwill” in our consolidated financial statements included herein.
Discontinuation of AZEDRA
On August 15, 2023, we announced our decision to discontinue the production and promotion of AZEDRA and that we would be winding down our Somerset, New Jersey manufacturing site. We will continue manufacturing AZEDRA into the first quarter of 2024, to the extent feasible, with the goal of providing doses of AZEDRA to current patients so they can complete their treatment regimen.
For more information, see Note 10, “Intangibles, Net and Goodwill” in our consolidated financial statements included herein.
Refinancing of 2019 Facility
In December 2022, we refinanced our existing credit facility, consisting of (i) a $200.0 million five-year term loan facility (the “2019 Term Facility”) and (ii) a $200.0 million five-year revolving credit facility (the “2019 Revolving Facility” and, together with the 2019 Term Facility, the “2019 Facility”), with a new $100.0 million delayed draw term loan facility (the “2022 Term Facility” and, the loans thereunder, the “Term Loans”) and a new $350.0 million five-year revolving credit facility (the “2022 Revolving Facility” and, together with the 2022 Term Facility, the “2022 Facility”).
We used approximately $7.8 million of cash on hand to primarily repay the principal amount of the loans outstanding related to the 2019 Facility through the nine months ended September 30, 2022. In addition, we used approximately $167.6 million of cash on hand to repay in full the aggregate remaining principal amount of the loans outstanding under the 2019 Facility and to pay related interest, transaction fees and expenses.
While the 2022 Term Facility allowed for a delayed draw term loan, the loan was not drawn upon. We recorded a loss on extinguishment of debt of $0.6 million related to the write-off of unamortized debt issuance costs and debt discounts associated with the 2019 Term Facility. In addition, we incurred and capitalized $2.7 million of new deferred financing costs related to the refinancing.
Issuance of Convertible Notes
60

Table of Contents

On December 8, 2022, we issued $575.0 million in aggregate principal amount of 2.625% Convertible Senior Notes due 2027 (the “Notes”), which includes $75.0 million in aggregate principal amount of the Notes sold pursuant to the full exercise of the initial purchasers’ option to purchase additional Notes. The Notes were issued under an indenture, dated as of December 8, 2022 (the “Indenture”), among the Company, LMI, as Guarantor, and U.S. Bank, as Trustee. The net proceeds from the issuance of the Notes were approximately $557.8 million, after deducting the initial purchasers’ discounts and offering expenses payable by us.
Key Factors Affecting Our Results
Our 2023 financial performance incorporates the results of the Cerveau Acquisition since the February 6, 2023 closing date.
Our business and financial performance have been, and continue to be, affected by the following:
Continued Growth of PYLARIFY
PYLARIFY, an F 18-labeled PET imaging agent targeting PSMA, was approved by the FDA in May 2021 and commercially launched in the U.S. in June 2021. PYLARIFY is indicated for PET imaging of PSMA-positive lesions in men with prostate cancer with suspected metastasis who are candidates for initial definitive therapy and in men with suspected recurrence based on elevated PSA levels. Both the National Comprehensive Cancer Center guidelines and the Society for Nuclear Medicine and Molecular Imaging appropriate use criteria note that PSMA PET imaging agents, including PYLARIFY, can be used for patient selection for PSMA-targeted radioligand therapy. PYLARIFY is available through a diverse, multi-partner network of PET manufacturing facilities (“PMFs”), including both commercial and academic partners.
The successful growth of PYLARIFY is dependent on our ability to sustain PYLARIFY as the leading PSMA PET imaging agent in an increasingly competitive marketplace. PYLARIFY’s competition includes two commercially available gallium-68-based PSMA imaging agents, an approved fluorine-18-based PSMA imaging agent, and other non-PSMA-based imaging agents commonly referred to as conventional imaging. We previously hired additional employees to assist us with the commercialization of PYLARIFY, including in Sales, Marketing, Reimbursement, Quality and Medical Affairs, and we will continue to make commercial investments necessary to drive PYLARIFY awareness and adoption. We believe that PYLARIFY currently has the largest dedicated field-based commercial team in the PSMA PET imaging agent space. Continued growth and revenue contribution from PYLARIFY will also depend on our ability to differentiate PYLARIFY in light of the potential loss of TPT Status, including through flexible and dependable access to PYLARIFY nationally, a best in class customer experience and through long-term strategic contracts.
Our HCPCS code, which enables streamlined billing, went into effect as of January 1, 2022. In addition, effective January 1, 2022, CMS granted TPT Status in the hospital outpatient setting for PYLARIFY, enabling traditional Medicare to provide an incremental payment for PET/CT scans performed with PYLARIFY in that setting. TPT Status for PYLARIFY could expire on December 31, 2024.
In 2023 rulemaking for the 2024 payment calendar year, CMS recognized the challenges of patient access to diagnostic radiopharmaceuticals and requested feedback on various payment alternatives that could provide separate reimbursement for these items, but the agency did not adopt any of these proposals in the final rule, while stating that it would continue to evaluate this issue in subsequent rulemaking. We intend to submit comments in connection with CMS’s 2024 rulemaking for 2025 payment calendar year to request that CMS establish separate payment for diagnostics instead of the current packaged payment following expiration of TPT Status.
Our plan to successfully grow PYLARIFY has also included highlighting its commercial and clinical value, as well as through strategic partnerships and collaborations, both for the commercialization of our product outside of the United States as well as for the use of our product potentially for additional indications or in connection with the development of PSMA-targeted therapeutics. With respect to commercializing PYLARIFY outside of the U.S., we previously licensed exclusive rights to Curium to develop and commercialize piflufolastat F 18 in Europe. In July 2023, Curium announced that it received marketing authorization for piflufolastat F 18 from the European Commission, which will be commercialized in the EU under the brand name PYLCLARI. With respect to the use of PYLARIFY in connection with the development of PSMA-targeted therapeutics, we have entered into multiple strategic collaborations with pharmaceutical companies. Additional information on collaborations using PYLARIFY are described further under Part I, Item 1. “Business - Strategic Partnerships and Other Revenue – Oncology.”
In connection with the acquisition of Progenics in June 2020, we issued CVRs tied to the financial performance of PYLARIFY. We paid $99.6 million to the CVR holders during May 2023 in full satisfaction of our obligations under the CVRs.
PYLARIFY AI Use
During 2021, we announced that EXINI was granted 510(k) clearance by the FDA in the U.S. and received CE marking in Europe for aPROMISE. We commercially launched aPROMISE under the name PYLARIFY AI in the U.S. in November 2021. During the second quarter of 2022, we received a new 510(k) clearance for an updated version of our PYLARIFY AI platform.

PYLARIFY AI is artificial intelligence medical device software designed to assist with the reading and quantification of PYLARIFY scans. The technology automatically analyzes a PSMA PET/CT image to segment anatomical regions – 51 bones and 12 soft tissue organs. This image segmentation enables automated localization, detection and quantification of potential PSMA-avid lesions in a PSMA PET/CT image, which data is then incorporated into the reporting system used by physicians.
During the third quarter of 2023, in collaboration with Curium, we customized and released our PYLARIFY AI platform for use in Europe. At the European Association of Nuclear Medicine meeting in Vienna, the PYLARIFY AI presentation was awarded the Top Rated Oral Presentation for response evaluation of metastatic prostate cancer patients.
Also in the third quarter of 2023, we announced a data agreement with the Prostate Cancer Clinical Trial Consortium (PCCTC) on its IRONMAN Registry for development and validation of PSMA biomarkers with PYLARIFY AI. The IRONMAN is the International Registry for Men with Advanced Prostate Cancer, the Registry is accumulating contextualized clinical and imaging data from more than 100 institutions across the globe.
During 2023, we also entered into an agreement with PIONEER (Prostate Cancer DIagnOsis and TreatmeNt Enhancement through the Power of Big Data in EuRope), led by the European Association of Urology (project Coordinator) and Bayer AG (private leader) to use our AI technology to help validate the clinical utility of PYLARIFY AI enabled PSMA biomarker to diagnose, treat and monitor prostate cancer patients. PIONEER is a European Network of Excellence for Big Data in Prostate Cancer, consisting of 34 private and public stakeholders in prostate cancer research and clinical care from across 9 countries.
Continued Growth of DEFINITY
We believe we will be able to increase use of DEFINITY through continued education of physicians and healthcare providers about the benefits of ultrasound enhancing agents in suboptimal echocardiograms. The U.S. market currently has three echocardiography ultrasound enhancing agents approved by the FDA; we estimate that DEFINITY will continue to hold at least an 80% share of the U.S. segment for ultrasound enhancing agents in echocardiography procedures.
As we continue to grow our microbubble franchise, our activities include:
Patents - We continue to actively pursue additional patents in connection with DEFINITY and DEFINITY RT, both in the U.S. and internationally. In the U.S. for DEFINITY, we have six Orange Book-listed method-of-use patents, one of which expires in 2035 and five of which expire in 2037, as well as additional manufacturing patents that are not Orange Book-listed expiring in 2037. For DEFINITY RT, we have eight Orange Book-listed patents, including two composition of matter patents which expire in 2035
VIALMIX RFID – DEFINITY is activated through the use of medical devices branded as VIALMIX and VIALMIX RFID. The activation rate and time are controlled by VIALMIX RFID through the use of radio-frequency identification technology (“RFID”) to ensure reproducible activation of DEFINITY. The RFID tag, which is affixed to the vial label, enables the DEFINITY vial to be appropriately activated with the VIALMIX RFID activation device.
DEFINITY RT - The formulation of DEFINITY that we have branded as DEFINITY RT allows both storage and shipment at room temperature and provides clinicians an additional choice and use in broader clinical settings. Given its physical characteristics, we believe DEFINITY RT is also well-suited for inclusion in kits requiring microbubbles for other indications and applications (including in kits developed by third parties of the type described further in the paragraph entitled “Microbubble Franchise” below).
Expansion of Strategic Partnerships and Other Revenue
We continue to seek ways to further increase the overall value of our portfolio of products and product candidates. We are evaluating a number of different opportunities to collaborate, in-license or acquire additional products, product candidates, businesses and technologies to drive our future growth. In particular, we are focused on late-stage radiopharmaceutical therapeutic and diagnostic product opportunities in oncology and other strategic areas that will complement our existing portfolio.
Our Strategic Partnerships and Other Revenue category includes our Strategic Partnerships, Pharma Solutions, and Digital Solutions businesses and is focused on enabling precision medicine with biomarkers and digital solutions.
Strategic Partnerships – We seek to monetize our assets through our Strategic Partnerships business, by optimizing core assets geographically and by driving value through non-core assets. For example, we have licensed the development and commercialization rights of PYLARIFY in Europe to Curium. Similarly, we licensed the commercialization rights for flurpiridaz fluorine-18 to GE Healthcare Limited.
Pharma Solutions – We use our Pharma Solutions business to offer our Biomarkers and Microbubble Platforms to pharmaceutical and start-up companies to support their research and development of therapeutic drugs and devices. The strategic goal of our Pharma Solutions business is to gain early access to innovation, de-risk the development, data generation
62

Table of Contents

and co-funding of our pipeline through collaborations, embed our technologies in the clinical ecosystem and establish the clinical utility of product candidates and research tools in our pipeline. Our Biomarkers are intended to support patient selection and the monitoring of disease progression. For example, piflufolastat F 18 is currently being used by Curium and Regeneron in those companies’ prostate cancer therapeutic drug development programs, and was also used in the development of PNT2002. Our acquisition of Cerveau in February 2023 added MK-6240 to our biomarker portfolio. MK-6240 is currently being used in more than ninety active clinical trials for several Alzheimer’s disease therapeutic candidates. Most recently, in collaboration with Ratio, we completed a Phase 1 study for LNTH-1363S, our novel fibroblast activation protein, alpha targeted, copper-64 labeled PET imaging agent candidate, to evaluate the pharmacokinetics, biodistribution and radiation dosimetry in adult healthy volunteers and plan to initiate a Phase 1/2a study in patients in 2024.
With respect to our Microbubble Platform, we generally enter into collaborations with partners that are designed to include our microbubble as part of a kit used with our partner’s medical device for therapeutic applications. In these collaborations, our microbubble is intended to be used as a vehicle to deliver a therapeutic drug.
Digital Solutions – Our Digital Solutions are designed to enhance imaging value and the throughput, reproducibility and reliability of image analysis, as well as to inform treatment selection and response to therapy. Our Digital Solutions include aPROMISE and aBSI (as defined below), both of which are FDA cleared and CE marked. aPROMISE, which is currently sold as PYLARIFY AI in the U.S., is artificial intelligence medical device software that is designed to allow healthcare professionals and researchers to perform standardized quantitative assessment of PSMA PET/CT images in prostate cancer, including those images obtained by using PYLARIFY. Automated Bone Scan Index (“aBSI”) automatically calculates the disease burden of prostate cancer by detecting and classifying bone scan tracer uptakes as metastatic or benign lesions using an artificial neural network. The software is currently used as one of the correlative objectives of the DORA trial, an open-labeled, randomized, Phase 3 study of docetaxel versus docetaxel in combination with radium-223 (Ra-223) in subjects with mCRPC. We offer our Digital Solutions to HCPs for clinical use and to pharmaceutical companies for development purposes, and in some cases, we also obtain clinical imaging data that we may use to further develop artificial intelligence solutions.
Global Mo-99 Supply
We currently have Mo-99 supply agreements with Institute for Radioelements (“IRE”), running through December 31, 2024, with auto-renewal provisions that are terminable upon notice of non-renewal, and with NTP Radioisotopes (“NTP”), acting for itself and on behalf of its subcontractor, the Australian Nuclear Science and Technology Organisation (“ANSTO”), running through December 31, 2024.
Although we believe we have the most globally diverse Mo-99 supply with IRE in Belgium, NTP in South Africa, and ANSTO in Australia, we still face supplier and logistical challenges in our Mo-99 supply chain. When one supplier experiences outages, we generally rely on Mo-99 supply from the other suppliers to limit the impact of the outages. We believe we effectively manage these various supply chain challenges, but depending on reactor and processor schedules and operations, at times we have not been able to fill some or all of the demand for our TechneLite generators on certain manufacturing days. A prolonged disruption of service from one of our three Mo-99 processing sites or one of their main Mo-99-producing reactors could have a negative effect on our business, results of operations, financial condition and cash flows.
Inventory Supply & Third Party Suppliers
We obtain a substantial portion of our imaging agents from third-party suppliers. Jubilant HollisterStier (“JHS”) is currently a significant supplier of DEFINITY and our sole source manufacturer of NEUROLITE, CARDIOLITE and evacuation vials. Our manufacturing and supply agreement with JHS (the “JHS MSA”) runs through December 31, 2027 and can be further extended by mutual agreement of the parties. The JHS MSA requires us to purchase from JHS specified percentages of our total requirements for DEFINITY, as well as specified quantities of NEUROLITE, CARDIOLITE and evacuation vial products, each year during the contract term. Either party can terminate the JHS MSA upon the occurrence of certain events, including the material breach or bankruptcy of the other party. In addition to JHS, we rely on SBL as our sole source manufacturer of DEFINITY RT.
In 2021, we completed the construction of a specialized in-house manufacturing facility at our North Billerica campus to produce the formulation of DEFINITY that requires refrigerated storage. On February 22, 2022, we received FDA approval of our supplemental new drug application authorizing commercial manufacturing of DEFINITY at our new facility. We believe this investment provides supply chain redundancy, improved flexibility and reduced costs in a potentially more price competitive environment.
Radiopharmaceuticals are decaying radioisotopes with half-lives ranging from a few hours to several days. Radiopharmaceutical finished goods, such as doses of PYLARIFY, cannot be kept in inventory because of their limited shelf lives and are subject to just-in-time manufacturing, processing and distribution, which takes place at our 54 PMF manufacturing sites across the U.S., with respect to PYLARIFY, and at our facilities in North Billerica, Massachusetts, with respect to our TechneLite generators and Xenon

Research and Development Expenses
To ensure we remain the leading radiopharmaceutical-focused company in our industry, we have historically made and will continue to make substantial investments in new product development and lifecycle management for existing products, including:
For PYLARIFY, we recently enrolled the first patient in a clinical trial to determine whether PYLARIFY can accurately detect the presence or absence of prostate cancer beyond the prostate gland in patients with favorable intermediate-risk prostate cancer, as well as how it may change the patient’s intended management. We are also exploring opportunities for the use of PYLARIFY beyond prostate cancer.
For PNT2002 and PNT2003, we were granted a license to exclusive worldwide rights (excluding certain countries) for $260.0 million in upfront payments during the fourth quarter of 2022 and will potentially make additional payments as described below. We also filed an ANDA for PNT2003 as described further in the section entitled “Exclusive License for PNT2002 and PNT2003” above.
For LNTH-1363S, in collaboration with Ratio, we recently completed a Phase 1 study for LNTH-1363S to evaluate the pharmacokinetics, biodistribution and radiation dosimetry in adult healthy volunteers. We plan to initiate a Phase 1/2a study in patients in 2024.
For 1095, our PSMA-targeted iodine-131-labeled small molecule product candidate, we enrolled the last patient in our ARROW Phase 2 study during the second quarter of 2022. Patients in this study will be followed for one year after their first treatment for all efficacy endpoints and survival and safety data will be collected for an additional year.
PNT2002
Under the terms of the PNT2002 License Agreement, Lantheus Two paid POINT an upfront cash payment of $250.0 million, and could pay up to an additional $281.0 million in milestone payments upon the achievement of specified U.S. and ex-U.S. regulatory milestones related to PNT2002. POINT is also eligible to receive up to $1.3 billion in sales milestone payments upon the achievement of specified annual sales thresholds of PNT2002. In addition, after Lantheus Two achieves $500.0 million in cumulative gross profit, POINT is eligible to receive royalty payments of twenty percent of net sales of PNT2002. Prior to achieving that financial recoupment threshold, POINT is eligible to receive royalty payments of twenty percent on that portion of annual net sales of PNT2002 that generate annual gross profit in excess of specified levels.
PNT2003
Under the terms of the PNT2003 License Agreement, Lantheus Three, LLC paid POINT an upfront cash payment of $10.0 million, and could pay up to an additional $34.5 million in milestone payments upon the achievement of specified U.S. and ex-U.S. regulatory milestones related to PNT2003. POINT is also eligible to receive up to $275.0 million in sales milestone payments upon the achievement of specified annual sales thresholds of PNT2003. In addition, POINT is eligible to receive royalty payments of fifteen percent of net sales of PNT2003.
Our investments in these additional clinical activities and lifecycle management opportunities will increase our operating expenses and impact our results of operations and cash flow, and we can give no assurances as to whether any of these clinical development candidates or lifecycle management opportunities will be successful.
Strategic Partnerships and Other Revenue
We continue to seek ways to further increase the overall value of our portfolio of products and product candidates. We are evaluating a number of different opportunities to collaborate, in-license or acquire additional products, product candidates, businesses and technologies to drive our future growth. In particular, we are focused on therapeutic and diagnostic radiopharmaceutical product opportunities in oncology and other strategic areas that will complement our existing portfolio.
Oncology
As we continue to pursue expanding our strategic partnerships, our Pharma Solutions activities in oncology are designed to enable precision medicine using biomarkers and digital solutions that augment diagnostic productivity. For example, in prostate cancer, we collaborate with pharmaceutical companies by supplying them with piflufolastat F 18 for use in their therapeutic drug development programs. For immuno-oncology, we intend to offer NM-01, a novel technetium-99m SPECT imaging agent that we are developing to assess PD-L1 expression in cancer cells, for potential use as an efficacy and safety biomarker in immuno-oncology therapies. With respect to pan-oncology, we are further exploring the use of LNTH-1363S as an innovative imaging biomarker that targets fibroblast activation protein.
Microbubble Franchise
In addition, we continue to expand our microbubble franchise. Some of our microbubble collaborations are with the following parties: (i) Cerevast Medical, Inc. (“Cerevast”), in which our microbubbles will be used in connection with Cerevast’s ocular ultrasound device to improve blood flow in occluded retinal veins in the eye; (ii) CarThera SAS, for the use of our microbubbles in
64

Table of Contents

combination with SonoCloud, a proprietary implantable device in development for the treatment of recurrent glioblastoma; (iii) Insightec Ltd. (“Insightec”), which will use our microbubbles in connection with the development of Insightec’s transcranial guided focused ultrasound device for the treatment of glioblastoma as well as other neurodegenerative conditions; (iv) Allegheny Health Network (“AHN”), which will use our microbubbles in combination with AHN’s ultrasound-assisted non-viral gene transfer technology for the development of a proposed treatment of xerostomia; and (v) SonoThera, which will use our microbubbles in combination with their ultrasound-guided, non-viral, gene therapy platform and treatments.
flurpiridaz
In September 2022, we announced with our strategic partner GE Healthcare Limited (“GE Healthcare”) that the recent Phase 3 clinical trial of our investigational radiotracer, flurpiridaz, had met its co-primary endpoints of exceeding a 60% threshold for both sensitivity and specificity for detecting coronary artery disease (“CAD”). The findings, shared at an American Society of Nuclear Cardiology conference, also demonstrated that cardiac PET imaging with flurpiridaz has higher diagnostic efficacy and image quality in patients with suspected CAD, compared with single photon emission computed tomography (“SPECT”) Myocardial Perfusion Imaging (“MPI”), the predominant procedure currently used in nuclear cardiology. We believe SPECT MPI represents approximately 6 million procedures per year in the U.S.
Under a Collaboration and License Agreement we entered into with GE Healthcare in 2017, GE Healthcare has led the funding and development of flurpiridaz, and, if the imaging agent is approved, will have the global commercialization rights for it. GE Healthcare recently announced that it had filed an NDA with the FDA for flurpiridaz. Assuming regulatory approval, we anticipate commercialization by GE Healthcare beginning in the second half of 2024. If flurpiridaz receives regulatory approval and is commercially successful, we will receive:
• up to $60 million in regulatory and sales milestone payments,
• tiered double-digit royalties on U.S. sales., and
• mid-single digit royalties on sales outside of the U.S.
Generally, our costs in connection with the strategic partnerships relate to intellectual property, the supply of drug and other ancillary expenses and the benefits can include possible supply, milestone and royalty payments, additional intellectual property rights and strategic relationships. For flurpiridaz, under the Collaboration and License Agreement, we retained ownership of all of the licensed intellectual property and bear the cost of patent prosecution and maintenance. We can give no assurance as to if or when or if any of these collaborations and other new initiatives, including our collaboration for flurpiridaz, will be successful or accretive to earnings.

Comparison of the Periods Ended December 31, 2023 and 2022
Revenues
We classify our revenues into three product categories: Radiopharmaceutical Oncology, Precision Diagnostics, and Strategic Partnerships and Other Revenue. Radiopharmaceutical Oncology consists of PYLARIFY and AZEDRA. In 2023, we announced our decision to discontinue the production and promotion of AZEDRA and we do not expect AZEDRA to contribute to the business after the first quarter of 2024. Precision Diagnostics includes DEFINITY, TechneLite and other diagnostic imaging products. Strategic Partnerships and Other Revenue primarily includes out-licensing arrangements and partnerships that focus on facilitating precision medicine through the use of biomarkers, digital solutions and radiotherapeutic platforms.
Revenues are summarized by product category on a net basis as follows:

Total revenues$1,296,429 $935,061 $425,208 $361,368 38.6 %
The increase in revenues for the year ended December 31, 2023, as compared to the prior year period, is primarily due to increased PYLARIFY and DEFINITY sales volume and RELISTOR milestone achievement of $15.0 million earned in the fourth quarter of 2023. The increase is offset, in part, by a decrease in Strategic Partnerships and Other Revenue due to the revenue recognized from the Novartis licensing agreement in the prior year described further under Note 3, “Disaggregation of Revenue” below and the sale of the RELISTOR royalty revenue asset.
Rebates and Allowances
Estimates for rebates and allowances represent our estimated obligations under contractual arrangements with third parties. Rebate accruals and allowances are recorded in the same period the related revenue is recognized, resulting in a reduction to revenue and the establishment of a liability which is included in accrued expenses. These rebates and allowances result from performance-based offers that are primarily based on attaining contractually specified sales volumes and growth, Medicaid rebate programs for our products, administrative fees of group purchasing organizations and certain distributor related commissions. The calculation of the accrual for these rebates and allowances is based on an estimate of the third-party’s expected purchases and the resulting applicable contractual rebate to be earned over a contractual period.
An analysis of the amount of, and change in, reserves for rebates and allowances is summarized as follows:

Table of Contents

Gross Profit
The increase in gross profit for the year ended December 31, 2023, as compared to the prior year period, is primarily due to increased PYLARIFY and DEFINITY sales volume and a RELISTOR milestone achievement, partially offset by the impairment of the AZEDRA currently marketed intangible asset, the Novartis licensing payment in the prior year, amortization of Cerveau intangible assets, and the loss of RELISTOR royalty revenue due to the sale of the asset.
Sales and Marketing
Sales and marketing expenses consist primarily of salaries and other related costs for personnel in field sales, marketing and customer service functions. Other costs in sales and marketing expenses include the development and utilization of advertising and promotional material, professional services, market research and sales meetings.
Sales and marketing expenses increased $41.5 million for the year ended December 31, 2023, as compared to the prior year period. This was primarily driven by our investment in sales and marketing efforts in support of an expansion of our PYLARIFY sales force and supporting functions intended to support and expand adoption of PYLARIFY and pre-commercialization activities for certain product candidates.
General and Administrative
General and administrative expenses consist of salaries and other related costs for personnel in executive, finance, legal, information technology and human resource functions. Other costs included in general and administrative expenses are professional fees for information technology services, external legal fees, consulting and accounting services as well as bad debt expense, certain facility and insurance costs, including director and officer liability insurance.
General and administrative expenses decreased $8.1 million for the year ended December 31, 2023 compared to the prior year period. This was primarily driven by a $44.1 million net reduction for the fair value adjustments to the contingent asset and liabilities (refer to Note 4, “Fair Value of Financial Instruments”, for further details on contingent consideration liabilities, including CVRs) and an insurance settlement in 2023. These reductions were partially offset by increased employee-related costs, investments in technology, new lease expense, and increased professional fees.
Research and Development
Research and development expenses relate primarily to the development of new products to add to our portfolio and costs related to our medical affairs, medical information and regulatory functions.
Research and development expenses decreased $234.0 million for the year ended December 31, 2023 as compared to the prior year period. This was primarily driven by the $260.0 million upfront payment in 2022 for the two agreements with POINT, partially offset by in-process research and development (“IPR&D”) impairment loss of $15.6 million in connection with our discontinuation of the production and promotion of AZEDRA and higher employee related costs driven by increased headcount.
Interest Expense
Interest expense for the year ended December 31, 2023 increased $12.8 million as compared to the prior year period due to the issuance of the Notes on December 8, 2022.
Loss on Extinguishment of Debt
During the year ended December 31, 2022, we realized a $0.6 million loss on extinguishment of debt related to the refinancing of our existed indebtedness. There were no extinguishments on debt for the year ended December 31, 2023.
Other (Income) Loss
Other (income) loss increased by $68.0 million for the year ended December 31, 2023 as compared to the prior year period primarily due to the gain on sale of the RELISTOR licensed intangible asset associated with net sales royalties of $51.8 million and an increase in interest income.
Income Tax Expense (Benefit)
Our effective tax rate for each reporting period is presented as follows:

Table of Contents

Year Ended
December 31,
20232022
Effective tax rate20.5%(5.0)%
Our effective tax rate in fiscal 2023 differs from the U.S. statutory rate of 21% primarily due to the income tax benefits associated with stock compensation deductions, additional net operating losses available for utilization under Internal Revenue Code Section 382 as a result of the sale of our RELISTOR royalty asset, and the release of uncertain tax positions, partially offset by state income taxes.
In accordance with our accounting policy, the change in the tax liabilities, penalties and interest associated with our uncertain tax positions (net of any offsetting federal or state benefit) is recognized within income tax expense (benefit). Our uncertain tax positions include indemnified liabilities, in accordance with the Stock and Asset Purchase Agreement entered into with BMS in 2008. Changes in the liability result in offsetting changes in the indemnification receivable. As these reserves change, adjustments are included in income tax expense while the offsetting adjustment is included in other income. Assuming that the receivable from BMS continues to be considered recoverable by us, there will be no effect on net income and no net cash outflows related to these liabilities. During 2023, the Company released a significant portion of its indemnified liability due to the settlement of these positions in certain states at a cost significantly less than our accrual resulting in $5.2 million (net of federal or state benefit) income tax benefit. Refer to Note 5, Income Taxes.
Our effective tax rate in fiscal 2022 differs from the U.S. statutory rate of 21% primarily due to the income tax benefit for the release of a portion of our uncertain tax positions and the tax benefit associated with stock compensation deductions offset by tax expense from the change in fair value of contingent consideration and expense generated on the revaluation of the Company’s deferred state tax rate. During 2022, the Company released a significant portion of its indemnified liability due to the settlement of these positions in various states at a cost significantly less than our accrual resulting in $9.6 million (net of federal or state benefit) income tax benefit.

Management’s Discussion and Analysis of Financial Condition and Results of Operations” of our annual report on Form 10-K for the fiscal year ended December 31, 2022, filed with the SEC on February 23, 2023.
Net Cash Provided by Operating Activities
Net cash provided by operating activities of $305.3 million during the year ended December 31, 2023 was primarily comprised of net income adjusted for the net effect of non-cash items such as impairment of long-lived assets, depreciation, amortization and accretion expense, gain on sale of our RELISTOR royalty asset, deferred income taxes, and stock-based compensation expense. The primary working capital sources of cash were the timing of payments to large vendors. The primary working capital uses of cash were a decrease to accruals related to the CVR payment, an increase in trade receivables associated primarily with the increase in PYLARIFY revenues, and an increase in inventory related to the timing of batch processes.
Net cash provided by operating activities of $281.8 million during the year ended December 31, 2022 was primarily comprised of net income adjusted for charges incurred in connection with acquired IPR&D and the net effect of non-cash items such as depreciation, amortization and accretion expense, the change in fair value of contingent assets and liabilities of $34.7 million (refer to Note 4, “Fair Value of Financial Instruments”, for further details on contingent consideration liabilities, including CVRs), and stock-based compensation expense. The primary working capital sources of cash were the increase in accruals associated with PYLARIFY sales. The primary working capital uses of cash were an increase in trade receivables associated primarily with the increase in PYLARIFY revenues.

Net Cash Provided by (Used in) Investing Activities
Net cash provided by investing activities during the year ended December 31, 2023 was primarily due to net cash proceeds of $97.8 million from the sale of our RELISTOR royalty asset offset by $45.3 million for our asset acquisition of Cerveau and $46.6 million of capital expenditures.
Net cash used in investing activities during the year ended December 31, 2022 was primarily due to the $260.0 million upfront payment to POINT and the $18.3 million of capital expenditures partially offset by $1.8 million received from the sale of our Puerto Rico subsidiary.
Net Cash (Used in) Provided by Financing Activities
Net cash used in financing activities during the year ended December 31, 2023 is primarily attributable to the payments for minimum statutory tax withholding related to net share settlement of equity awards of $14.4 million and the CVR initial valuation as of June 30, 2020 of $3.7 million, offset by proceeds of $3.8 million from stock option exercises.
Net cash provided by financing activities during the year ended December 31, 2022 is primarily attributable to the proceeds of $557.8 million received from the issuance of the Notes, proceeds of $7.5 million from stock option exercises and proceeds of $5.6 million from the voluntarily terminated interest rate swap contracts in connection with the refinancing of debt. These amounts were offset by payments on long-term debt and other borrowings of $175.0 million, repurchase of common stock of $75.0 million and payments for minimum statutory tax withholding related to net share settlement of equity awards of $7.8 million.
External Sources of Liquidity
In December 2022, we voluntarily repaid our 2019 $200.0 million five-year term loan facility. In addition, we replaced our $200.0 million revolving facility with the 2022 Revolving Facility. The terms of the 2022 Revolving Facility are set forth in the Credit Agreement, dated as of December 2, 2022, by and among us, the lenders from time to time party thereto and Citizens Bank, N.A., as administrative agent and collateral agent (the “2022 Credit Agreement”). We have the right to request an increase to the 2022 Revolver Facility or request the establishment of one or more new incremental term loan facilities, in an aggregate principal amount of up to $335.0 million or consolidated EBITDA for the four consecutive fiscal quarters most recently ended, plus additional amounts, in certain circumstances.
The Company used approximately $7.8 million of cash on hand to primarily repay the principal amount of the loans outstanding related to the 2019 Facility through the nine months ended September 30, 2022. In addition, in December 2022, the Company used approximately $167.6 million of cash on hand to repay in full the aggregate remaining principal amount of the loans outstanding under the 2019 Facility and to pay related interest, transaction fees and expenses.
Under the terms of the 2022 Revolving Facility, the lenders thereunder agreed to extend credit to us from time to time until December 2, 2027 consisting of revolving loans in an aggregate principal amount not to exceed $350.0 million at any time. The 2022 Revolving Facility includes a $20.0 million sub-facility for the issuance of letters of credit (the “Letters of Credit”). The 2022 Revolving Facility includes a $10.0 million sub-facility for swingline loans (the “Swingline Loans”). The Letters of Credit, Swingline Loans and the borrowings under the 2022 Revolving Facility are expected to be used for working capital and other general corporate purposes.
Please refer to Note 12, “Long-Term Debt, Net, and Other Borrowings” for further details on the 2022 Facility.
As of December 31, 2023, we were in compliance with all financial and other covenants under the 2022 Credit Agreement.
On December 8, 2022, we issued $575.0 million in aggregate principal amount of the Notes, which includes $75.0 million in aggregate principal amount of Notes sold pursuant to the full exercise of the initial purchasers’ option to purchase additional Notes. The Notes were issued under an indenture, dated as of December 8, 2022 (the “Indenture”), among the Company, LMI, as Guarantor, and U.S. Bank, as Trustee. The net proceeds from the issuance of the Notes were approximately $557.8 million, after deducting the initial purchasers’ discounts and offering expenses payable by us.
On March 31, 2021, we voluntarily repaid in full the entire outstanding principal on outstanding debt of Progenics that we assumed as a result of the Progenics Acquisition. The total amount we paid was $30.9 million, which included a prepayment amount of $0.5 million.
Our ability to fund our future capital needs will be affected by our ability to continue to generate cash from operations and may be affected by our ability to access the capital markets, money markets or other sources of funding, as well as the capacity and terms of our financing arrangements.
71

Table of Contents

We may from time to time repurchase or otherwise retire our debt and take other steps to reduce our debt or otherwise improve our balance sheet. These actions may include prepayments of our term loans or other retirements or refinancing of outstanding debt, privately negotiated transactions or otherwise. The amount of debt that may be retired, if any, could be material and would be decided at the sole discretion of our Board and will depend on market conditions, our cash position and other considerations.
Funding Requirements
Our future capital requirements will depend on many factors, including:
The level of product sales and the pricing environment of our currently marketed products, particularly PYLARIFY and DEFINITY, as well as any additional products that we may market in the future;
Revenue mix shifts and associated volume and selling price changes that could result from contractual status changes with key customers and additional competition;
The continued costs of the ongoing commercialization of our products;
Our investment in the further clinical development and commercialization of products and development candidates, including PNT2002, PNT2003, 1095 and MK-6240;
The costs of acquiring or in-licensing, developing, obtaining regulatory approval for, and commercializing, new products, businesses or technologies, including any potential related milestone or royalty payments, together with the costs of pursuing opportunities that are not eventually consummated;
The costs of investing in our facilities, equipment and technology infrastructure;
The costs and timing of establishing or amending manufacturing and supply arrangements for commercial supplies of our products and raw materials and components;
Our ability to have products manufactured and released from manufacturing sites in a timely manner in the future, or to manufacture products at our in-house manufacturing facilities in amounts sufficient to meet our supply needs;
The costs of further commercialization of our existing products, particularly in international markets, including product marketing, sales and distribution and whether we obtain local partners to help share such commercialization costs;
The legal costs relating to maintaining, expanding and enforcing our intellectual property portfolio, pursuing insurance or other claims and defending against product liability, regulatory compliance, intellectual property or other claims, including the patent infringement claim related to the filing of our ANDA for PNT2003;
The cost of interest on any additional borrowings which we may incur under our financing arrangements; and
The impact of sustained inflation on our costs of goods sold and operating expenses.
Disruption in our financial performance could occur if we experience significant adverse changes in product or customer mix, broad economic downturns, sustained inflation, adverse industry or company conditions or catastrophic external events, including pandemics such as COVID-19, natural disasters and political or military conflict. If we experience one or more of these events in the future, we may be required to further implement expense reductions, such as a delay or elimination of discretionary spending in all functional areas, as well as scaling back select operating and strategic initiatives.
If our capital resources become insufficient to meet our future capital requirements, we would need to finance our cash needs through public or private equity offerings, debt financings, assets securitizations, sale-leasebacks or other financing or strategic alternatives, to the extent such transactions are permissible under the covenants of our 2022 Credit Agreement. Additional equity or debt financing, or other transactions, may not be available on acceptable terms, if at all. If any of these transactions require an amendment or waiver under the covenants in our 2022 Credit Agreement, which could result in additional expenses associated with obtaining the amendment or waiver, we will seek to obtain such an amendment or waiver to remain in compliance with those covenants. However, we cannot provide assurance that such an amendment or waiver would be granted, or that additional capital will be available on acceptable terms, if at all.
At December 31, 2023, our only current committed external source of funds is our borrowing availability under our 2022 Revolving Facility. We had $713.7 million of cash and cash equivalents as of December 31, 2023. Our 2022 Revolving Facility contains a number of affirmative, negative, reporting and financial covenants, in each case subject to certain exceptions and materiality thresholds. Incremental borrowings under the 2022 Revolving Facility may affect our ability to comply with the covenants including the financial covenants restricting consolidated net leverage and interest coverage. Accordingly, we may be limited in utilizing the full amount of our 2022 Revolving Facility as a source of liquidity.

Table of Contents

Based on our current operating plans, we believe our balance of cash and cash equivalents, which totaled $713.7 million as of December 31, 2023, along with cash generated by ongoing operations and continued access to our 2022 Revolving Facility, will be sufficient to satisfy our cash requirements over the next twelve months and beyond. Our material cash requirements include the following contractual and other obligations.
Debt
We completed a sale of $575.0 million in aggregate principal amount of the Notes due in 2027. As of December 31, 2023, we had no amounts of principal due within the next twelve months. Future interest payments associated with the Notes total $60.0 million, with $15.1 million payable within twelve months.
Leases
We have operating lease arrangements for certain facilities, including corporate and manufacturing space. As of December 31, 2023, we had fixed operating lease payment obligations of $99.5 million, with $4.6 million payable within twelve months.
We have lease arrangements for certain equipment. As of December 31, 2023, we had fixed finance lease payment obligations of $1.7 million, with $0.8 million payable within twelve months.
Purchase Obligations
We have purchase obligations that primarily consist of noncancelable obligations related to minimum quantities of goods or services that have been committed to be purchased on an annual basis. As of December 31, 2023, we had minimum purchase obligations of $10.9 million, with $2.7 million due within twelve months.
License Agreements
We have entered into license agreements in which fixed payments have been committed to be paid on an annual basis. As of December 31, 2023, we had no amount of fixed license payments due within twelve months. These amounts do not include potential milestone or contractual payment obligations contingent upon the achievement or occurrence of future milestones or events under our license agreements, because they are contingent and the amounts and timing of such potential obligations are unknown or uncertain. We may be required to pay additional amounts up to approximately $264.4 million in contingent payments under our license agreements.
Asset Acquisitions
During 2022, we entered into the POINT License Agreements, in which we made upfront payments of $260.0 million, and under which we may make additional milestone payments. The additional milestone payments are based on FDA approval and net sales and commercial milestones. Under the terms of the PNT2002 License Agreement, we have the potential to pay up to an additional $281.0 million in milestone payments and up to $1.3 billion in sales milestone payments upon the achievement of specified annual sales thresholds. Under the terms of the PNT2003 License Agreement, we have the potential to pay an additional $34.5 million in milestone payments and up to $275.0 million in sales milestone payments upon the achievement of specified annual sales thresholds. In total, we may be required to pay up to approximately $1.8 billion related to the asset acquisition. As of December 31, 2023, these contingent payments were not expected to be payable due to the uncertainty around the timing of the future cash flows.
On February 6, 2023, the Company acquired Cerveau and made an upfront payment of approximately $35.3 million to the Selling Stockholders. The Company paid the Selling Stockholders an additional $10.0 million in May 2023 upon the successful completion of a technology transfer. The Company could pay up to an additional $51.0 million in milestone payments upon achievement of specified U.S. regulatory milestones related to MK-6240. The Selling Stockholders are also eligible to receive up to $1.2 billion in sales milestone payments upon the achievement of specified annual commercial sales thresholds of MK-6240 in the event the Company pursues commercialization, as well as up to $13.5 million in research revenue milestones upon achievement of specified annual research revenue thresholds. Additionally, the Company will pay to the Selling Stockholders up to double-digit royalty payments for research revenue and commercial sales. As of December 31, 2023, these contingent payments were not expected to be payable due to the uncertainty around the timing of the future cash flows.
Other Long-Term Liabilities
Our other long-term liabilities in the consolidated balance sheet include the fair values of contingent consideration liabilities including contingent consideration liabilities related to a previous acquisition completed by Progenics in 2013. We may be required to pay up to approximately $85.0 million related to the contingent consideration. As of December 31, 2023, these contingent payments were not expected to be payable within twelve months due to the uncertainty around the timing of the future cash flows.
73

Table of Contents

Our other long-term liabilities in the consolidated balance sheet include unrecognized tax benefits and related interest and penalties. As of December 31, 2023, we had unrecognized tax benefits of $3.2 million, which included interest and penalties, classified as noncurrent liabilities. At this time, we are unable to make a reasonably reliable estimate of the timing of payments in individual years in connection with these tax liabilities.
Asset Retirement Obligation
We are required to provide the Massachusetts Department of Public Health and the New Jersey Department of Environmental Protection financial assurance demonstrating our ability to fund the decommissioning of our North Billerica, Massachusetts and Somerset, New Jersey production facilities, respectively, upon closure. We have provided this financial assurance in the form of a $30.3 million surety bond (the “Surety Bond”). As of December 31, 2023, the liability, which was approximately $22.9 million, was measured at the present value of the obligation expected to be incurred of approximately $25.1 million. These contingent payments are not expected to be payable within twelve months due to the uncertainty around the timing of the future cash flows related to the decommissioning of our radioactive operations.
Off-Balance Sheet Arrangements
As noted above, we have provided the Surety Bond to the Massachusetts Department of Public Health and New Jersey Department of Environmental Protection.
Since inception, we have not engaged in any other off-balance sheet arrangements, including structured finance, special purpose entities or variable interest entities.
Effects of Inflation
We do not believe that inflation has had a significant impact on our revenues or results of operations. We expect our cost of product sales and other operating expenses will change in the future in line with periodic inflationary changes in price levels. Because we intend to retain and continue to use our property and equipment, we believe that the incremental inflation related to the replacement costs of those items will not materially affect our operations. However, the rate of inflation affects our expenses, such as those for employee compensation and contract services, which could increase our level of expenses and the rate at which we use our resources. While we generally believe that we will be able to offset some of the effect of price-level changes by adjusting our product prices and implementing operating efficiencies, any material unfavorable changes in price levels could have a material adverse effect on our financial condition, results of operations and cash flows.
Recent Accounting Standards
Refer to Note 2, “Summary of Significant Accounting Policies,” in the accompanying consolidated financial statements located under Item 8 of this Annual Report on Form 10-K for information regarding recently issued accounting standards that may have a significant impact on our business.
Critical Accounting Policies
The discussion and analysis of our financial condition and results of operations are based on our consolidated financial statements, which have been prepared in accordance with U.S. GAAP. The preparation of these consolidated financial statements require us to make estimates and judgments that affect our reported assets and liabilities, revenues and expenses, and other financial information. Actual results may differ materially from these estimates under different assumptions and conditions. In addition, our reported financial condition and results of operations could vary due to a change in the application of a particular accounting standard.
We believe the following represent our critical accounting estimates used in the preparation of our financial statements.
Revenue from Contracts with Customers
Revenue is measured based on a consideration specified in a contract with a customer, and excludes any sales incentives and amounts collected on behalf of third parties. We recognize revenue when we satisfy our performance obligations by transferring control over products or services to our customers. The amount of revenue we recognize reflects the consideration to which we expect to be entitled to receive in exchange for these goods or services. To achieve this core principle, we apply the following five steps: (1) identify the contracts with a customer; (2) identify the performance obligations in the contract; (3) determine the transaction price; (4) allocate the transaction price to the performance obligations in the contract; and (5) recognize revenue when (or as) we satisfy performance obligations.
We derive our revenues through arrangements with customers for product sales as well as licensing and royalty arrangements. We sell our products primarily to hospitals, independent diagnostic testing facilities, and radiopharmacies, and we consider customer purchase orders, which in some cases are governed by master sales or group purchasing organization agreements, to be contracts with
74

Table of Contents

our customers. In addition to these arrangements, we also enter into licensing agreements under which we license certain rights to third parties. The terms of these arrangements typically include payment to us of one or more of the following: non-refundable, up-front license fees; development, regulatory and commercial milestone payments; and royalties on net sales of licensed products. We analyze various factors requiring management judgment when applying the five-step model to our contracts with customers.
Our product revenues are recorded at the net sales price (transaction price), which represents our sales price less estimates related to reserves which are established for items such as discounts, returns, rebates and allowances that may be provided for in certain contracts with our customers. Judgment is used in determining and updating our reserves on an ongoing basis, and where appropriate, these estimates take into consideration a range of possible outcomes which are probability-weighted for relevant factors such as our historical experience, current contractual and statutory requirements, specific known market events and trends, industry data and forecasted customer buying and payment patterns. Overall, these reserves reflect our best estimates of the amount of consideration to which it is entitled based on the terms of the contract. Actual amounts of consideration ultimately received may differ from our estimates.
For our licensing and royalty arrangements, we use judgment in determining the number of performance obligations in a license agreement by assessing whether the license is distinct or should be combined with another performance obligation as well as the nature of the license. As part of the accounting for these arrangements, we develop assumptions that require judgment to determine the stand-alone selling price for each performance obligation identified in a contract. These key assumptions may include market conditions, reimbursement rates for personnel costs, development timelines and probabilities of regulatory success.
Business Combinations
We account for business combinations using the acquisition method of accounting. We recognize the assets acquired and liabilities assumed in business combinations on the basis of their fair values at the date of acquisition. We assess the fair value of assets acquired, including intangible assets, and liabilities assumed using a variety of methods. Each asset acquired and liability assumed is measured at fair value from the perspective of a market participant. The method used to estimate the fair values of intangible assets incorporates significant assumptions regarding the estimates a market participant would make in order to evaluate an asset, including a market participant’s use of the asset and the appropriate discount rates. Acquired IPR&D is recognized at fair value and initially characterized as an indefinite-lived intangible asset, irrespective of whether the acquired IPR&D has an alternative future use. Any excess purchase price over the fair value of the net tangible and intangible assets acquired is allocated to goodwill. Transaction costs and restructuring costs associated with a business combination are expensed as incurred.
The fair values assigned to tangible and intangible assets acquired and liabilities assumed are based on our estimates and assumptions, as well as other information we have compiled, including valuations that utilize customary valuation procedures and techniques. If the actual results differ from the estimates and assumptions used in these estimates, it could result in a possible impairment of the intangible assets and goodwill, a required acceleration of the amortization expense of finite-lived intangible assets or the recognition of additional consideration, which would be expensed.
During the measurement period, which extends no later than one year from the acquisition date, we may record certain adjustments to the carrying value of the assets acquired and liabilities assumed with the corresponding offset to goodwill. After the measurement period, all adjustments are recorded in the consolidated statements of operations as operating expenses or income.
Intangible and Long-Lived Assets
We test intangible and long-lived assets for recoverability whenever events or changes in circumstances suggest that the carrying value of an asset or group of assets may not be recoverable. We measure the recoverability of assets to be held and used by comparing the carrying amount of the asset to future undiscounted net cash flows expected to be generated by the asset. If those assets are considered to be impaired, the impairment equals the amount by which the carrying amount of the assets exceeds the fair value of the assets. Any impairments are recorded as permanent reductions in the carrying amount of the assets. Long-lived assets, other than goodwill and other intangible assets, that are held for sale are recorded at the lower of the carrying value or the fair market value less the estimated cost to sell.
Intangible assets, consisting of trademarks, customer relationships, currently marketed products, licenses and developed technology are amortized in a method equivalent to the estimated utilization of the economic benefit of the asset.
Costs of IPR&D intangible assets acquired as part of an asset acquisition that have no alternative future use are expensed when incurred. Milestone payments made after regulatory approval are capitalized as an intangible asset and amortized over an estimated useful life of the product. Cash payments related to acquired IPR&D intangible assets are reflected as an investing cash flow in the Company's consolidated statement of cash flows.
75

Table of Contents

Our IPR&D intangible assets include intangible assets acquired in a business combination that are used in research and development activities but have not yet reached technological feasibility, regardless of whether they have alternative future use. The primary basis for determining the technological feasibility or completion of these projects is whether we have obtained regulatory approval to market the underlying products in an applicable geographic region. Because obtaining regulatory approval can include significant risks and uncertainties, the eventual realized value of the acquired IPR&D projects may vary from their fair value at the date of acquisition. We classify IPR&D intangible assets acquired in a business combination as an indefinite-lived intangible asset until the completion or abandonment of the associated research and development efforts. Upon completion of the associated research and development efforts, we will determine the useful life and begin amortizing the assets to reflect their use over their remaining lives. Upon permanent abandonment, we write-off the remaining carrying amount of the associated IPR&D intangible asset. We test our IPR&D intangible assets at least annually or when a triggering event occurs that could indicate a potential impairment and we recognize any impairment loss in our consolidated statements of operations.

Item 7A. Quantitative and Qualitative Disclosures about Market Risk
We are exposed to market risk from changes in interest rates and foreign currency exchange rates. We may from time to time use derivative financial instruments or other financial instruments to hedge these economic exposures related to foreign currencies. We do not hold or issue financial instruments for trading purposes.
Interest Rate Risk
We are subject to interest rate risk in connection with our 2022 Revolving Facility, which is variable rate indebtedness. Interest rate changes could increase the amount of our interest payments and thus negatively impact our future earnings and cash flows. As of December 31, 2023, there was availability of $350.0 million on the 2022 Revolving Facility. Any increase in the interest rate under the 2022 Revolving Facility may have a negative impact on our future earnings to the extent we have outstanding borrowings under the 2022 Revolving Facility.
We had used interest rate swaps to reduce the variability in cash flows associated with a portion of our forecasted interest payments on its variable rate debt. We voluntarily terminated our interest rate swap contracts on December 2, 2022.
Foreign Currency Risk
We face exposure to movements in foreign currency exchange rates whenever we, or any of our subsidiaries, enter into transactions with third parties that are denominated in currencies other than our, or that subsidiary’s, functional currency. Intercompany transactions between entities that use different functional currencies also expose us to foreign currency risk.
During the years ended December 31, 2023, 2022 and 2021, the net impact of foreign currency changes on transactions was a loss of less than $0.1 million, $0.3 million and $0.3 million, respectively. From time to time, we enter into foreign currency forward contracts primarily to reduce the effects of fluctuating foreign currency exchange rates. We may enter into additional foreign currency forward contracts when deemed appropriate. We do not enter into foreign currency forward contracts for speculative or trading purposes.
The Canadian dollar presents the primary currency risk on our earnings. At December 31, 2023, a hypothetical 10% change in value of the U.S. dollar relative to the Canadian dollar would not have materially affected our financial instruments.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Stockholders and the Board of Directors of Lantheus Holdings, Inc.
Opinion on the Financial Statements
We have audited the accompanying consolidated balance sheets of Lantheus Holdings, Inc. and subsidiaries (the "Company") as of December 31, 2023 and 2022, the related consolidated statements of operations, comprehensive income (loss), changes in stockholders’ equity, and cash flows, for each of the three years in the period ended December 31, 2023, and the related notes (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2023 and 2022, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2023, in conformity with accounting principles generally accepted in the United States of America.
We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 22, 2024, expressed an unqualified opinion on the Company's internal control over financial reporting.
Basis for Opinion
These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.
Critical Audit Matter
The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements that was communicated or required to be communicated to the audit committee and that (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.
Intangible Assets — Non-Cash Impairment Charge for AZEDRA Intangible Asset Group — Refer to Note 10 to the financial statements
Critical Audit Matter Description
In March 2023, the Company stopped all development activities in relation to a future indication associated with AZEDRA, which was classified as an in-process research and development (“IPR&D”) intangible asset. The asset group, which consisted of the IPR&D asset and a currently marketed product (the “AZEDRA intangible asset group”), was assessed for impairment. The Company considered several factors in estimating the future projections of revenues and cash flows of the AZEDRA intangible asset group as part of the impairment testing. The Company concluded that the carrying amount exceeded the fair value of the AZEDRA intangible asset group, which had no value. As a result of such assessment, the Company recorded a non-cash impairment charge in research and development expenses relating to the IPR&D asset and a non-cash impairment charge in cost of goods sold relating to the currently marketed indication of AZEDRA in the consolidated statement of operations for the year ended December 31, 2023.
We identified management’s estimates of future projections of revenue and cash flows used to determine the fair value of the AZEDRA intangible asset group used to record the non-cash impairment charge as a critical audit matter because of the significant estimates made by management. This required a high degree of auditor judgment and an increased extent of effort when performing audit procedures to evaluate the reasonableness of management’s estimates of future projections of revenues and cash flows.
78

Table of Contents

How the Critical Audit Matter Was Addressed in the Audit
Our audit procedures related to management’s estimates of future revenues and cash flows used to record the non-cash impairment charge for the AZEDRA intangible asset group included the following, among others:
We tested the effectiveness of controls over management’s review of the estimates of future projections of revenue and cash flows used to record the non-cash impairment charge for the AZEDRA intangible asset group.
We assessed the reasonableness of management’s estimates of future projections of revenues and cash flows for the AZEDRA intangible asset group by:
Comparing historical results to the Company’s strategic plans.
Making inquiries of management and corroborating inquiries with the Company’s strategic planning group.
Reading internal communications to management and the Board of Directors.
We evaluated whether the estimates of future projections of revenues and cash flows for AZEDRA were consistent with evidence obtained in other areas of the audit.
