Lantheus Holdings Inc

1. Description of Business

Lantheus Holdings, Inc., a Delaware corporation, is the parent company of Lantheus Medical Imaging, Inc. (“LMI”) and LMI is the parent company of Progenics Pharmaceuticals, Inc., a Delaware corporation (“Progenics”). See“Progenics Acquisition” below and Note 21,“Acquisition of Assets,” to these consolidated financial statements respectively, for more information.

The Company develops, manufactures and commercializes innovative diagnostic and therapeutic products that assist clinicians in the diagnosis and treatment of cancer, heart disease and other diseases. The Company believes its diagnostic products result in improved diagnostic information that enables healthcare providers to better detect and characterize, or rule out, disease, potentially achieving improved patient outcomes, reducing patient risk and limiting overall costs throughout the healthcare system.

The Company’s 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. The Company believes that its diagnostic products provide information that enables healthcare providers to better detect and characterize, or rule out, disease, with the potential to achieve better patient outcomes, reduce patient risk, and limit overall costs.

The Company produces and markets its products throughout the United States (the “United States” or the “U.S.”), selling primarily to hospitals, independent diagnostic testing facilities, and radiopharmacies. The Company sells its 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.

Sales of the Company’s prostate cancer diagnostic imaging agent, PYLARIFY (as defined below), are generated in the U.S. through an internal PYLARIFY sales team, as well as a sales team at some of the Company’s positron emission tomography (“PET”) manufacturing facilities (“PMF”) partners. Sales of the Company’s ultrasound enhancing agent, DEFINITY, are generated in the U.S. through an internal DEFINITY sales team. In the U.S., the Company’s other nuclear imaging products, including TechneLite, Xenon-133, NEUROLITE and CARDIOLITE, are primarily sold to commercial radiopharmacies, the majority of which are controlled by or associated with PharmaLogic Holdings Corp, Cardinal Health, RLS, United Pharmacy Partners, and Jubilant Radiopharma. Research revenue is derived from existing partnerships with pharmaceutical companies and academic institutions that use our products and product candidates in clinical trials and includes milestone and dose-related payments. A small portion of the Company’s nuclear imaging product sales in the U.S. are generated through the Company’s internal sales force to hospitals and clinics that maintain their own in-house radiopharmaceutical preparation capabilities.

In Europe, Australia, Asia-Pacific, Central America and South America, the Company generally relies on third-party distributors to market, sell and distribute its nuclear imaging and ultrasound enhancing agent products, either on a country-by-country basis or on a multi-country regional basis. The Company’s executive offices are located in Bedford, Massachusetts, with additional offices in North Billerica, Massachusetts, Montreal, Canada and Lund, Sweden.

Progenics Acquisition

On June 19, 2020 (the “Closing Date”), pursuant to the Amended and Restated Agreement and Plan of Merger, dated as of February 20, 2020 (the “Merger Agreement”), by and among Holdings, Plato Merger Sub, Inc., a wholly-owned subsidiary of Holdings (“Merger Sub”), and Progenics, Holdings completed the acquisition of Progenics by means of a merger of Merger Sub with and into Progenics, with Progenics surviving such merger as a wholly-owned subsidiary of Holdings (the “Progenics Acquisition”).

In connection with the Progenics Acquisition, Lantheus Holdings issued 26,844,877 shares of Lantheus Holdings common stock and 86,630,633 contingent value rights (each a “CVR”) tied to the financial performance of PYLARIFY to former Progenics stockholders and option holders. Each CVR entitled its holder to receive a pro rata share of aggregate cash payments equal to 40% of U.S. net sales generated by PYLARIFY in 2022 and 2023 in excess of $100.0 million and $150.0 million, respectively. The Company’s aggregate payments in respect of the CVRs, together with any other non-stock consideration treated as paid in connection with the Progenics Acquisition, was capped at 19.9% of the total consideration the Company paid in the Progenics Acquisition. Based on the Company’s 2022 PYLARIFY net sales, the Company determined that the aggregate payment obligation under the CVRs was $99.6 million, which was the maximum amount payable. The Company paid out this amount in May 2023 in full satisfaction of the CVRs.

2. Summary of Significant Accounting Policies

Basis of Presentation and Principles of Consolidation

The accompanying consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”). The consolidated financial statements include the accounts of the Company and its direct and indirect wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.

Use of Estimates

The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period. The estimates reflected in the Company’s consolidated financial statements include, but are not limited to, certain judgments regarding revenue recognition, goodwill, tangible and intangible asset valuation, inventory valuation, asset retirement obligations, contingent assets and liabilities, income tax liabilities and related indemnification receivable, deferred tax assets and liabilities and accrued expenses. Actual results could materially differ from those estimates or assumptions.

Revenue Recognition

The Company recognizes revenue when it transfers control of promised goods or services to its customers in an amount that reflects the consideration to which the Company expects to be entitled to in exchange for those goods and services. See Note 3, “Revenue from Contracts with Customers,” to these consolidated financial statements, for further discussion on revenues.

Accounts Receivable, net

Accounts receivable consist of amounts billed and currently due from customers. The Company maintains an allowance for doubtful accounts for estimated current expected credit losses. In determining the allowance, consideration includes the probability of recoverability based on past experience as well as current and future economic and market conditions. Certain accounts receivable may be fully reserved when the Company becomes aware of any specific collection issues. The Company periodically reviews the aging of receivables, payment history and customer creditworthiness to determine if adjustments to the allowance for doubtful accounts is necessary. Allowance for doubtful accounts was $7.8 million at December 31, 2024 and de minimis at December 31, 2023.

Income Taxes

The Company accounts for income taxes using an asset and liability approach. Income tax expense (benefit) represents income taxes paid or payable for the current year plus the change in deferred taxes during the year. Deferred taxes result from differences between the financial and tax bases of the Company’s assets and liabilities. Deferred tax assets and liabilities are measured using the currently enacted tax rates that apply to taxable income in effect for the years in which those tax attributes are expected to be recovered or paid, and are adjusted for changes in tax rates and tax laws when such changes are enacted.

The Company recognizes deferred tax assets to the extent that the Company believes that these assets are more-likely-than-not to be realized. Valuation allowances are recorded to reduce deferred tax assets when it is more-likely-than-not that the future tax benefit will not be realized. The assessment of whether or not a valuation allowance is required involves weighing both positive and negative evidence, including both historical and prospective information, with greater weight given to evidence that is objectively verifiable. A history of recent losses is negative evidence that is difficult to overcome with positive evidence. In evaluating prospective information there are four sources of taxable income: reversals of taxable temporary differences, items that can be carried back to prior tax years (such as net operating losses), pre-tax income, and prudent and feasible tax planning strategies. Adjustments to the deferred tax valuation allowances are made in the period when those assessments are made.

The Company accounts for uncertain tax positions using a two-step recognition threshold and measurement analysis method to determine the financial statement impact of uncertain tax positions taken or expected to be taken in a tax return. Differences between tax positions taken in a tax return and amounts recognized in the financial statements are recorded as adjustments to other long-term assets and liabilities, or adjustments to deferred taxes, or both. The Company records the related interest and penalties to income tax expense (benefit).

Net Income per Common Share

The Company computes earnings per share using the two-class method. Basic earnings per common share is computed by dividing net income by the weighted-average number of shares of common stock outstanding during the period. Diluted earnings per common share is computed by dividing net income by the weighted-average number of shares of common stock outstanding during the period, plus the potential dilutive effect of other securities as if those securities were converted or exercised. The Company’s potentially dilutive shares, which could include shares issuable upon conversion of the $575.0 million in aggregate principal amount of 2.625% Convertible Senior Notes due 2027 (the “Notes”), are considered to be common stock equivalents and are only included in the calculation of diluted net income per share when their effect is dilutive. The Company has the option to settle the Notes through cash settlement or a combination of cash and share settlement provided that the principal is settled in cash and the conversion spread is settled in cash or shares as elected by the Company. The Company applies the if-converted method for diluted earnings in order to reflect the conversion spread. During periods in which the Company incurs net losses, both basic and diluted loss per common share is calculated by dividing the net loss by the weighted-average shares of common stock outstanding and potentially dilutive securities are excluded from the calculation because their effect would be antidilutive.

Cash and Cash Equivalents

Cash and cash equivalents include savings deposits, certificates of deposit and money market funds that have original maturities of three months or less when purchased.

Restricted Cash

Restricted cash as of December 31, 2024 and 2023, represents primarily collateral for a letter of credit securing a lease obligation and a security deposit. The Company believes the carrying value of these assets approximates fair value.

Concentration of Risks and Limited Suppliers

Financial instruments which potentially subject the Company to concentrations of credit risk consist principally of trade accounts receivable. The Company periodically reviews its accounts receivable for collectability and provides for an allowance for doubtful accounts to the extent that amounts are not expected to be collected. The Company sells primarily to hospitals, independent diagnostic testing facilities, and radiopharmacies.

As of December 31, 2024 and 2023, no customer accounted for greater than 10% of accounts receivable, net. No customer accounted for greater than 10% of revenues for the years ended December 31, 2024, 2023 and 2022.

The Company relies on certain materials used in its development and manufacturing processes, some of which are procured from only one or a few sources. The failure of one of these suppliers to deliver on schedule could delay or interrupt the manufacturing or commercialization process and would adversely affect the Company’s operating results. In addition, a disruption in the commercial supply of, or a significant increase in the cost of one of the Company’s materials from these sources could have a material adverse effect on the Company’s business, financial position and results of operations.

The Company currently relies on Jubilant HollisterStier as its significant manufacturer of DEFINITY and its sole source manufacturer of NEUROLITE, CARDIOLITE and evacuation vials for TechneLite. The Company has Molybdenum-99 supply agreements with Institute for Radioelements of Belgium, running through December 31, 2025, with auto-renewal provisions and terminable upon notice of non-renewal, and with NTP Radioisotopes and its subcontractor Australian Nuclear Science and Technology Organisation, running through December 31, 2025.

The following table sets forth revenues for each of the Company’s products representing 10% or more of revenues:

Inventory

Inventory includes material, direct labor and related manufacturing overhead and is stated at the lower of cost and net realizable value on a first-in, first-out basis. The Company records inventory when the Company takes title to the product. The majority of the value of the inventory relates to non-radioactive products. With respect to the Company’s products that are radiopharmaceuticals, due to the limited shelf life of such products, they are generally not held as finished goods.

The Company assesses the recoverability of inventory to determine whether adjustments for excess and obsolete inventory are required. Inventory that is in excess of future requirements is written down to its estimated net realizable value based on product shelf life, forecasted demand and other factors.

Inventory costs associated with product that has not yet received regulatory approval are capitalized if the Company believes there is probable future commercial use of the product and future economic benefits of the asset. If future commercial use of the product is not probable, then inventory costs associated with such product are expensed as incurred. The Company had no inventory pending regulatory approval as of December 31, 2024 and 2023.

Property, Plant and Equipment, net

Property, plant & equipment are stated at cost. Replacements of major units of property are capitalized, and replaced properties are retired. Replacements of minor components of property and repair and maintenance costs are charged to expense as incurred. Certain costs to obtain or develop computer software are capitalized and amortized over the estimated useful life of the software. Depreciation and amortization are computed on a straight-line basis over the estimated useful lives of the related assets and recorded in costs of goods sold and operating expenses in the associated functional expense category which utilizes the associated asset. The estimated useful lives of the major classes of depreciable assets are as follows:

Upon retirement or other disposal of property, plant & equipment, the cost and related amount of accumulated depreciation are removed from the asset and accumulated depreciation accounts, respectively. The difference, if any, between the net asset value and the proceeds is included in operating income.

Included within machinery and equipment are spare parts. Spare parts include replacement parts relating to plant & equipment and are either recognized as an expense when consumed or reclassified and capitalized as part of the related asset and depreciated over the remaining useful life of the related asset.

Business Combinations

The Company accounts for business combinations using the acquisition method of accounting. The Company recognizes the assets acquired and liabilities assumed in business combinations on the basis of their fair values at the date of acquisition. The Company assesses 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 in-process research and development (“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.

During the measurement period, which extends no later than one year from the acquisition date, the Company 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.

Goodwill

Goodwill is not amortized but is instead tested for impairment at least annually and whenever events or circumstances indicate that it is more likely-than-not that it may be impaired. The Company has elected to perform the annual test for goodwill impairment as of October 31st of each year.

In performing the Company’s annual assessment, the Company is permitted to first perform a qualitative test and if necessary, perform a quantitative test. If the Company is required to perform the quantitative impairment test of goodwill, the Company compares the fair value of a reporting unit to its carrying value. If the reporting unit’s carrying value exceeds its fair value, the Company would record an impairment loss to the extent that the carrying value of goodwill exceeds its implied fair value. The Company estimates the fair value of its reporting units using discounted cash flow or other valuation models, such as comparative transactions and market multiples. The Company performed a qualitative assessment and didnot recognize any goodwill impairment charges during the years ended December 31, 2024, 2023 or 2022.

Intangible and Long-Lived Assets

The Company tests 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. The Company measures 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. See Note 7,“Property, Plant and Equipment, Net” to these consolidated financial statements for further details on impairment. 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 patents, trademarks, customer relationships, a currently marketed product, licenses and developed technology related to the Company’s products 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.

The Company’s IPR&D intangible assets includes 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 obtaining 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. The Company classifies 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, the Company will determine the useful life and begin amortizing the assets to reflect their use over their remaining lives. Upon permanent abandonment, the Company writes-off the remaining carrying amount of the associated IPR&D intangible asset. IPR&D intangible assets are tested at least annually as of October 31st or when a triggering event occurs that could indicate a potential impairment and any impairment loss is recognized in the Company’s consolidated statements of operations. See Note 10,“Intangibles, Net and Goodwill” to these consolidated financial statements for further details on impairment.

Contingencies

In the normal course of business, the Company is subject to loss contingencies, such as legal proceedings and claims arising out of its business, that cover a wide range of matters, including, among others, product and environmental liability. The Company records accruals for those loss contingencies when it is probable that a liability will be incurred and the amount of loss can be reasonably estimated. The Company does not recognize gain contingencies until realized.

Convertible Notes

The Company evaluates convertible notes to determine if those contracts or embedded components of those contracts qualify as derivatives to be separately accounted for. The change in fair value of any separately recognized derivative is recorded in the consolidated statement of operations as other income or expense. Upon conversion, exercise or cancellation of a derivative instrument, the instrument is marked to fair value at the date of conversion, exercise or cancellation.

Fair Values of Financial Instruments

The estimated fair values of the Company’s financial instruments, including its cash and cash equivalents, accounts receivable, accounts payable and accrued expenses approximate the carrying values of these instruments due to their short term nature. The Company’s long-term debt has triggering events that would impact the fair value of the instruments. The Company determined that no triggering event has occurred during the years ended December 31, 2024 and December 31, 2023. As of December 31, 2024 and 2023, the fair value of the Company’s convertible debt was estimated to be approximately $765.3 million and $644.3 million, respectively, based on quoted market prices of these instruments and was classified as a Level 1 measurement within the fair value hierarchy. For more information on the fair value, see Note 4,“Fair Value of Financial Instruments”to these consolidated financial statements.

Contingent Consideration Liabilities

The estimated fair value of contingent consideration liabilities are initially measured and recorded on the acquisition date. The contingent consideration liabilities are considered to be Level 3 instruments and are reviewed quarterly, or whenever events or circumstances occur that indicate a change in fair value. The contingent consideration liabilities are recorded at fair value at the end of each reporting period with changes in estimated fair values recorded in general and administrative expenses in the consolidated statements of operations.

The estimated fair value is determined based on probability adjusted discounted cash flows and Monte Carlo simulation models that include significant estimates and assumptions pertaining to commercialization events and sales targets. The most significant unobservable inputs are the probabilities of achieving regulatory approval of the development projects and subsequent commercial success.

Significant changes in any of the probabilities of success would result in a significantly higher or lower fair value measurement. Significant changes in the probabilities as to the periods in which milestones will be achieved would result in a significantly lower or higher fair value measurement.

The Company's acquisitions accounted for as asset acquisitions may also include contingent consideration payments to be made for sales-based milestones, development and regulatory milestones. The Company assesses whether such contingent consideration meets the definition of a derivative. Contingent consideration payments in an asset acquisition not required to be accounted for as derivatives are recognized when the contingency is resolved, and the consideration is paid or becomes payable. Contingent consideration payments required to be accounted for as derivatives are recorded at fair value on the date of the acquisition and are subsequently remeasured to fair value at each reporting date. Upon recognition of the contingent consideration payment, the amount is included in the cost of the acquired asset or group of assets.

Derivative Instruments

The Company has used interest rate swaps to reduce the variability in cash flows associated with a portion of the Company’s forecasted interest payments on its variable rate debt. To qualify for hedge accounting, the hedging instrument must be highly effective at reducing the risk from the exposure being hedged. Further, the Company must formally document the hedging relationship at inception and, on at least a quarterly basis, continually reevaluate the relationship to ensure it remains highly effective throughout the life of the hedge. The Company does not enter into derivative financial instruments for speculative or trading purposes.

Advertising and Promotion Costs

Advertising and promotion costs are expensed as incurred. During the years ended December 31, 2024, 2023 and 2022, the Company incurred $29.7 million, $26.0 million and $26.0 million, respectively in advertising and promotion costs, which are included in sales and marketing in the consolidated statements of operations.

Research and Development

Research and development costs are expensed as incurred and relate primarily to the development of new products to add to the Company’s portfolio and costs related to its medical affairs and medical information functions. Nonrefundable advance payments for goods or services that will be used or rendered for future research and development activities are deferred and recognized as an expense as the goods are delivered or the related services are performed.

Foreign Currency

The consolidated statements of operations of the Company’s foreign subsidiaries are translated into U.S. Dollars using weighted-average exchange rates. The net assets of the Company’s foreign subsidiaries are translated into U.S. Dollars using the end of period exchange rates. The impact from translating the net assets of these subsidiaries at changing rates are recorded in the foreign currency translation adjustment account, which is included in accumulated other comprehensive loss in the consolidated balance sheets.

Remeasurement of the Company’s foreign currency denominated transactions are included in net income. Transaction gains and losses are reported as a component of other (income) loss, net in the consolidated statements of operations.

Stock-Based Compensation

The Company’s stock-based compensation cost is measured at the grant date of the stock-based award based on the fair value of the award and is recognized as expense over the requisite service period, which generally represents the vesting period, and includes an estimate of the awards that will be forfeited. The Company estimates the fair value of each stock-based award on its measurement date using either the current market price of the stock, the Black-Scholes option valuation model or the Monte Carlo simulation valuation model, whichever is most appropriate. The Black-Scholes and Monte Carlo simulation valuation models incorporate assumptions such as stock price volatility, the expected life of options or awards, a risk-free interest rate and dividend yield.

Expected volatility is based on the historical volatility of the Company’s stock price. The risk-free interest rates are based on quoted U.S. Treasury rates for securities with maturities approximating the awards’ expected lives. Expected lives are principally based on the Company’s historical exercise experience with previously issued awards. The expected dividend yield iszero as the Company has never paid dividends and does not currently anticipate paying any in the foreseeable future.

Expense for performance restricted stock awards is recognized based upon the fair value of the awards on the date of grant and the number of shares expected to vest based on the terms of the underlying award agreement and the requisite service period(s).

Other (Income) Loss, Net

Other (income) loss, net consisted of the following:

Comprehensive Income

Comprehensive income consists of net income and other gains and losses affecting stockholders’ equity that, under U.S. GAAP, are excluded from net income. For the Company, other comprehensive income consists of foreign currency translation gains and losses, as well as realized gains and losses on cash flow hedges related to the Company’s interest rate swaps. The accumulated other comprehensive loss balance consists entirely of foreign currency translation gains and losses and realized and unrealized gains and losses on outstanding cash flow hedges related to the Company’s interest rate swaps.

Asset Retirement Obligations

The Company’s compliance with federal, state, local and foreign environmental laws and regulations may require it to remove or mitigate the effects of the disposal or release of chemical substances in jurisdictions where it does business or maintains properties. The Company establishes accruals when those costs are legally obligated and can be reasonably estimated. Accrual amounts are estimated, which may include the assistance of third-party environmental specialists, and are based on currently available information, regulatory requirements, remediation strategies, historical experience, the relative shares of the total remediation costs, a relevant discount rate, and the time periods of when estimated costs can be reasonably predicted. Changes in these assumptions could impact the Company’s future reported results.

The Company has production facilities which manufacture and process radioactive materials at its sites in North Billerica, Massachusetts and, through March 1, 2024, Somerset, New Jersey. The Company considers its legal obligation to remediate its facilities upon a decommissioning of its radioactive-related operations as an asset retirement obligation. The fair value of a liability for asset retirement obligations is recognized in the period in which the liability is incurred. The liability is measured at the present value of the obligation expected to be incurred and is adjusted in subsequent periods as accretion expense is recorded. The corresponding asset retirement costs are capitalized as part of the carrying values of the related long-lived assets and depreciated over the assets’ useful lives.

The Company has identified conditional asset retirement obligations related to the future removal and disposal of asbestos contained in certain of the buildings located on the Company’s North Billerica campus. The Company believes the asbestos is appropriately contained and it is compliant with all applicable environmental regulations. If these properties undergo major renovations or are demolished, certain environmental regulations are in place, which specify the manner in which asbestos must be handled and disposed. The Company is required to record the fair value of these conditional liabilities if they can be reasonably estimated. As of December 31, 2024 and 2023, sufficient information was not available to estimate a liability for such conditional asset retirement obligations as the obligations to remove the asbestos from these properties have indeterminable settlement dates. As such, no liability for conditional asset retirement obligations has been recorded in the accompanying consolidated balance sheets as of December 31, 2024 and 2023.

Self-Insurance Reserves

The Company’s consolidated balance sheets at December 31, 2024 and 2023 include $2.8 million and $1.0 million of accrued liabilities associated with employee medical costs that are retained by the Company, respectively. The Company estimates the required liability of those claims on an undiscounted basis based upon various assumptions which include, but are not limited to, the Company’s historical loss experience and projected loss development factors. The required liability is also subject to adjustment in the future based upon changes in claims experience, including changes in the number of incidents (frequency) and change in the ultimate cost per incident (severity).

Recent Accounting Pronouncements

Accounting Pronouncements Adopted During the Period

During the fourth quarter of 2024, the Company adopted Accounting Standard Update (“ASU”) 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures,” which was issued by the Financial Accounting Standards Board (the “FASB”) in December 2023. ASU 2023-07 requires all public entities, including public entities with a single reportable segment, to provide in interim and annual periods one or more measures of segment profit or loss used by the chief operating decision maker to allocate resources and assess performance. Additionally, the standard requires disclosures of significant segment expenses and other segment items, as well as incremental qualitative disclosures. See Note 22,“Segment Information” to these consolidated financial statements for additional disclosures.

Accounting Pronouncements Not Yet Adopted

In November 2024, the FASB issued ASU 2024-04,“Debt - Debt with Conversion and Other Options (Subtopic 470-20),”which clarifies the requirements for determining whether certain settlements of convertible debt instruments should be accounted for as an induced conversion rather than as extinguishment of debt. The requirements of ASU 2024-04 are effective for the annual periods beginning after December 15, 2025, including interim periods within those fiscal years. Early adoption is permitted. For the Company, the requirements under ASU 2024-04 will be effective for its Quarterly Report on Form 10-Q for the first quarter 2026. The Company is currently in the process of evaluating the effects of this pronouncement on our consolidated financial results and related disclosures.

In November 2024, the FASB issued ASU 2024-03,“Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40),”and in January 2025, the FASB issued ASU 2025-01,“Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Clarifying the Effective Date.”ASU 2024-03 requires additional income statement disclosures, including the disaggregation of specific categories of expenses underlying the line items presented on the income statement. Additionally, ASU 2024-03 requires enhanced disclosure of selling expenses. As clarified by ASU 2025-01, the requirements of the guidance are effective for annual periods beginning after December 15, 2026 and interim periods within fiscal years beginning after December 15, 2027. For the Company, annual reporting requirements under ASU 2024-03 will be effective for its Annual Report on Form 10-K for the year ending December 31, 2027 and interim reporting requirements will be effective beginning in the first quarter of 2028. Early adoption is permitted and the amendments should be applied on a prospective basis, however retrospective application is permitted. The Company is currently in the process of evaluating the effects of this pronouncement on our consolidated financial results and related disclosures.

In December 2023, the FASB also issued ASU 2023-09,“Income Taxes (Topic 740): Improvements to Income Tax Disclosures,” which requires enhanced income tax disclosures, including specific categories and disaggregation of information in the effective tax rate reconciliation, disaggregated information related to income taxes paid, income or loss from continuing operations before income tax expense or benefit, and income tax expense or benefit from continuing operations. The requirements of the ASU are effective for annual periods beginning after December 15, 2024, with early adoption permitted. The Company is currently in the process of evaluating the impact of this pronouncement on our related disclosures.

3. Revenue from Contracts with Customers

Revenue Recognition

Revenue is recognized when a customer obtains control of promised goods or services. The amount of revenue recognized reflects the consideration to which the Company expects to be entitled to receive in exchange for these goods or services. To achieve this core principle, the Company applies 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) the Company satisfies a performance obligation.

Disaggregation of Revenue

The following table summarizes revenue by revenue source as follows:

(1)The Company’s product revenue includes PYLARIFY and DEFINITY, among other products. This category represents the delivery of physical goods. The Company applies the same revenue recognition policies and judgments for all of its principal products.

(2)The Company recognized $24.0 million license revenue in the first quarter of 2022 related to an agreement with Novartis Pharma AG.

The Company classifies its revenues into three product categories: Radiopharmaceutical Oncology, Precision Diagnostics, and Strategic Partnerships and Other Revenue. Radiopharmaceutical Oncology includes PYLARIFY and AZEDRA. In the first quarter of 2024, the Company discontinued the production of AZEDRA. Precision Diagnostics includes DEFINITY, TechneLite and other diagnostic imaging products. Strategic Partnerships and Other Revenue includes out-licensing arrangements and partnerships for the Company’s biomarker solutions, digital solutions, and radiotherapeutic platforms, inclusive of two investigational late-stage diagnostic agents, MK-6240 and NAV-4694. On August 2, 2023, the Company sold the RELISTOR net sales royalty asset (the “RELISTOR royalty asset”) under its license agreement with Bausch Health Companies, Inc. (“Bausch”); the Company retained the rights to future sales-based milestone payments. No sales-based milestone payment was earned in 2024. During the fourth quarter of 2023, the Company earned a sales-based milestone payment of $15.0 million.

On January 31, 2022, the Company entered into a global settlement agreement with Novartis Pharma AG (“Novartis”), Advanced Accelerator Applications USA, Inc., Endocyte, Inc. and their affiliates (the “Novartis Agreement”) to settle certain disputes between the parties. Under the Novartis Agreement, Novartis agreed to make a lump sum payment to the Company, as well as to reimburse the Company for certain fees and expenses in connection with certain German litigation, and the Company agreed to license certain intellectual property to Novartis. In addition, the Company agreed to supply PYLARIFY for clinical purposes at an arms-length value which will be recorded revenue in the future as product is provided. In accordance with the Company's ASC 606, “Revenue from Contracts with Customers”, assessment, Novartis is considered to be a customer. The Company determined that the $24.0 million constituted a single element which was satisfied on the date of the execution of the Novartis Agreement. The Company determined that the license of intellectual property carried a fair value of $24.0 million. As such, the Company assigned the value to the fair value of the license, which constitutes the entire transaction price and does not require further allocation. The Company determined that the $24.0 million represented the point at which the licensee was able to use and benefit from the license and recognized revenue when the license was granted to Novartis upon execution of the Novartis Agreement. The Company recognized the $24.0 million fee as revenue on its consolidated statement of operations for the quarter ended March 31, 2022. The Company received the $24.0 million payment in April 2022.

Revenue by product category on a net basis is as follows:

Product Revenue, Net

The Company sells its products principally to hospitals, independent diagnostic testing facilities, and radiopharmacies. The Company considers customer purchase orders, which in some cases are governed by master sales or group purchasing organization agreements, to be the contracts with a customer.

For each contract, the Company considers the promise to transfer products, each of which is distinct, to be the identified performance obligations. In determining the transaction price, the Company evaluates whether the price is subject to refund or adjustment to determine the net consideration to which the Company expects to be entitled.

The Company typically invoices customers upon satisfaction of identified performance obligations. As the Company’sstandard payment terms are 30 to 60 days from invoicing, the Company has elected to use the significant financing component practical expedient.

The Company allocates the transaction price to each distinct product based on their relative standalone selling price. The product price as specified on the purchase order is considered the standalone selling price as it is an observable input which depicts the price as if sold to a similar customer in similar circumstances.

Revenue is recognized when control of the product is transferred to the customer (i.e., when the Company’s performance obligation is satisfied), which typically occurs upon delivery to the customer. Further, in determining whether control has transferred, the Company considers if there is a present right to payment and legal title, along with risks and rewards of ownership having transferred to the customer.

Frequently, the Company receives orders for products to be delivered over multiple dates that may extend across several reporting periods. The Company invoices for each delivery upon shipment and recognizes revenues for each distinct product delivered, assuming transfer of control has occurred.

The Company generally does not separately charge customers for shipping and handling costs, but any shipping and handling costs charged to customers are included in product revenue, net. Taxes collected from customers relating to product sales and remitted to governmental authorities are excluded from revenues.

Variable Consideration

Revenues from product sales are recorded at the net sales price (transaction price), which includes estimates of variable consideration for which reserves are established for discounts, returns, rebates and allowances that are offered within contracts between the Company and its customers. These reserves are based on the amounts earned or to be claimed on the related sales and are classified as a current liability. Where appropriate, these estimates take into consideration a range of possible outcomes which are probability-weighted for relevant factors such as the Company’s 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 the Company’s best estimates of the amount of consideration to which it is entitled based on the terms of the contract. The amount of variable consideration which is included in the transaction price may be constrained, and is included in the net sales price only to the extent that it is probable that a significant reversal in the amount of the cumulative revenue recognized will not occur in a future period. Actual amounts of consideration ultimately received may differ from the

Company’s estimates. If actual results in the future vary from the Company’s estimates, the Company adjusts these estimates, which would affect product revenue and earnings in the period such variances become known.

Rebates and Allowances: The Company provides certain customers with rebates and allowances that are explicitly stated in the Company’s contracts and are recorded as a reduction of revenue in the period the related product revenue is recognized. The Company establishes a liability for such amounts, which is included in accrued expenses and other liabilities in the accompanying consolidated balance sheets. These rebates and allowances result from performance-based offers that are primarily based on attaining contractually specified sales volumes and administrative fees the Company is required to pay to group purchasing organizations. The Company estimates the amount of rebates and allowances that are explicitly stated in the Company’s contracts based on a combination of actual purchases and an estimate of the customer’s buying patterns.

Product Returns: The Company generally offers customers a limited right of return due to non-conforming product. The Company estimates the amount of its product sales that may be returned by its customers and records this estimate as a reduction of revenue in the period the related product revenue is recognized. The Company currently estimates product return liabilities using its historical product return information and considers other factors that it believes could significantly impact its expected returns, including product recalls. Reserves for product returns are not significant to the Company due to the nature of its products including radiopharmaceutical products with limited half-lives.

An analysis of the amount of, and change in, reserves is summarized as follows:

License and Royalty Revenues

The Company has entered into licensing agreements, under which it licenses certain rights to third parties. The terms of these arrangements typically include payment to the Company 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. The Company also has distribution licenses which are treated as combined performance obligations with the delivery of its products and are classified as product revenue, net.

In determining the appropriate amount of revenue to be recognized as it fulfills its obligations under each of its agreements, the Company performs the five-step approach stated earlier. The Company uses 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, the Company must develop assumptions that require judgment to determine the stand-alone selling price for each performance obligation identified in the contract. The Company uses key assumptions to determine the stand-alone selling price, which may include market conditions, reimbursement rates for personnel costs, development timelines and probabilities of regulatory success.

Licenses of intellectual property: If the license to the Company’s intellectual property is determined to be distinct from the other performance obligations identified in the arrangement, the Company recognizes revenues from non-refundable, up-front fees allocated to the license when the license is transferred to the customer and the customer is able to use and benefit from the license. For licenses that are bundled with other promises, the Company utilizes judgment to assess the nature of the combined performance obligation to determine whether the combined performance obligation is satisfied over time or at a point in time and, if over time, the appropriate method of measuring progress for purposes of recognizing revenue from non-refundable, up-front fees. The Company evaluates the measure of progress each reporting period and, if necessary, adjusts the measure of performance and related revenue recognition.

Milestone Payments: At the inception of each arrangement that includes development or sales milestone payments, the Company evaluates whether the milestones are considered probable of being reached and estimates the amount to be included in the transaction price using the most likely amount method. If it is probable that a significant revenue reversal would not occur, the associated milestone value is included in the transaction price. Milestone payments that are outside the control of the Company or the licensee, such as regulatory approvals, are not considered probable of being achieved until those approvals are received. The transaction price is then allocated to each performance obligation on a relative stand-alone selling price basis, for which the Company recognizes revenue as or when the performance obligations under the contract are satisfied. At the end of each subsequent reporting period, the Company re-evaluates the probability of achievement of such milestones and any related constraint, and if necessary, adjusts its estimate of the overall transaction price. Any such adjustments are recorded on a cumulative catch-up basis, which would affect license and royalty revenues and earnings in the period of adjustment. At December 31, 2024, the variable consideration for the milestone payments is constrained and is excluded from contract price until the milestone is achieved by the customer.

Royalty Revenues: For arrangements that include sales-based royalties, including milestone payments based on the level of sales, and the license is deemed to be the predominant item to which the royalties relate, the Company recognizes revenue at the later of (i) when the related sales occur, or (ii) when the performance obligation to which some or all of the royalty has been allocated has been satisfied (or partially satisfied).

Contract Costs

The Company recognizes an asset for incremental costs of obtaining a contract with a customer if it expects to recover those costs. The Company’s sales incentive compensation plans qualify for capitalization since these plans are directly related to sales achieved during a period of time. However, the Company has elected the practical expedient to expense the costs as they are incurred, within sales and marketing expenses, since the amortization period is less than one year.

The Company recognized certain revenues as follows:

The Company did not record any revenue related to performance obligations satisfied (or partially satisfied) in previous periods during the years ended December 31, 2024 and 2023.

The Company’s performance obligations are typically part of contracts that have an original expected duration of one year or less. As such, the Company is not disclosing the aggregate amount of the transaction price allocated to performance obligations that are unsatisfied (or partially satisfied) as of the end of the reporting period.

4. Fair Value of Financial Instruments

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. In order to increase consistency and comparability of fair value measurements, financial instruments are categorized based on a hierarchy that prioritizes observable and unobservable inputs used to measure fair value into three broad levels, which are described below:

•Level 1 — Inputs are unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date.

•Level 2— Inputs include quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (i.e., interest rates, yield curves, etc.) and inputs that are derived principally from or corroborated by observable market data by correlation or other means (market corroborated inputs).

•Level 3 — Unobservable inputs that reflect a Company’s estimates about the assumptions that market participants would use in pricing the asset or liability. The Company develops these inputs based on the best information available, including its own data.

The Company’s financial assets and liabilities measured at fair value on a recurring basis consist of money market funds, interest rate swaps, contingent consideration liabilities and equity investments. The Company invests excess cash from its operating cash accounts in overnight investments and reflects these amounts in cash and cash equivalents in the consolidated balance sheets at fair value using quoted prices in active markets for identical assets. The fair value of the interest rate swaps is determined based on observable market-based inputs, including interest rate curves and reflects the contractual terms of these instruments, including the period to maturity. Please refer to Note 13,“Derivative Instruments,” to these consolidated financial statements for further details on the interest rate swaps. Investment in equity securities resulting from the Perspective Therapeutics, Inc. (“Perspective”) and Radiopharm Theranostics Limited (“Radiopharm”) strategic agreements were recorded at fair value by the Company and are adjusted for price changes observable in the market each quarter. The Company recorded the contingent consideration liabilities resulting from the Progenics Acquisition at fair value based on inputs that are not observable in the market.

The tables below present information about the Company’s assets and liabilities measured at fair value on a recurring basis:

During the years ended December 31, 2024 and 2023, there were no transfers into or out of Level 3.

Perspective Therapeutics, Inc. Equity Securities

At December 31, 2024, the Company held 11,677,339 shares of Perspective common stock (“Perspective Shares”). The Company accounts for its investment in Perspective Shares as an equity investment with a readily determinable fair value, as the securities are publicly traded on the New York Stock Exchange (“NYSE”). The fair value of the equity securities is based on the closing price of the Perspective Shares on the NYSE at the end of the fiscal period and is classified within Level 1 of the fair value hierarchy because the equity securities are valued using quoted market prices. The fair value of the Perspective Shares as of December 31, 2024 was approximately $37.3 million based on a closing market price of $3.19 per share on December 31, 2024, resulting in an unrealized loss of $41.0 million for the year ended December 31, 2024. See Note 21,“Acquisition of Assets” to these consolidated financial statements for further discussion of the Perspective transaction.

Radiopharm Theranostics Limited Equity Securities

At December 31, 2024, the Company held 149,625,180 shares of Radiopharm common stock (“Radiopharm Shares”). The Company accounts for its investment in Radiopharm Shares as an equity investment with a readily determinable fair value, as the securities are publicly traded on the Australian Stock Exchange (“ASX”). The fair value of the equity securities is based on the closing price of the Radiopharm Shares on the ASX at the end of the fiscal period and is classified within Level 1 of the fair value hierarchy because the equity securities are valued using quoted market prices. The fair value of the Radiopharm Shares as of December 31, 2024 was approximately $2.2 million based on the converted closing market price of approximately $0.01 per share on December 31, 2024, resulting in an unrealized loss on equity securities of $2.6 million for the year ended December 31, 2024. See Note 21,“Acquisition of Assets”to these consolidated financial statements for further discussion of the Radiopharm transaction.

Contingent Consideration

The Company assumed contingent consideration liabilities related to a previous acquisition completed by Progenics in 2013 (“2013 Acquisition”). These contingent consideration liabilities include potential payments of up to $70.0 million if the Company attains certain net sales targets primarily for AZEDRA and 1095 (also known as 131 I-MIP-1095) and a $5.0 million 1095 commercialization milestone. Additionally, there is a potential payment of up to $10.0 million for a commercialization milestone related to a prostate cancer product candidate the Company refers to as “1404” that was out-licensed to ROTOP Pharmaka GmbH. The Company’s total potential payments related to the 2013 Acquisition are approximately $85.0 million. The Company considers the contingent consideration liabilities relating to the 2013 Acquisition each a Level 3 instrument (one with significant unobservable inputs) in the fair value hierarchy. The estimated fair value of these was determined based on probability adjusted discounted cash flows and Monte Carlo simulation models that included significant estimates and assumptions pertaining to commercialization events and sales targets. The most significant unobservable inputs with respect to 1095 and 1404 are the probabilities of achieving regulatory approval of those development projects and subsequent commercial success.

Significant changes in any of the probabilities of success, the probabilities as to the periods in which sales targets and milestones will be achieved, discount rates or underlying revenue forecasts would result in a significantly higher or lower fair value measurement. The Company records the contingent consideration liability at fair value with changes in estimated fair values recorded in general and administrative expenses in the consolidated statements of operations. The Company can give no assurance that the actual amounts paid, if any, in connection with the contingent consideration liabilities will be consistent with any recurring fair value estimate of such contingent consideration liabilities.

The following tables summarize quantitative information and assumptions pertaining to the fair value measurement of liabilities using Level 3 inputs as of December 31, 2024 and 2023.

For those financial instruments with significant Level 3 inputs, the following table summarizes the activities for the periods indicated:

The change in fair value of the contingent financial liabilities resulted in a decrease of general and administrative expense of $1.2 million for the year ended December 31, 2024. In August 2024, the Company entered into a bill of sale with the holder of a significant portion of the contingent milestone rights related to the 2013 Acquisition (the “2013 Milestone Rights”) to transfer the holder’s portion of the 2013 Milestone Rights back to the Company for $1,000. This buyout resulted in a $1.5 million decrease in general and administrative expense during 2024 due to the reduction in outstanding 2013 Milestone Rights.

5. Income Taxes

The components of income before income taxes consists of the following:

The Company’s income tax expense (benefit) consists of the following:

The reconciliation of income taxes at the U.S. federal statutory rate to the income tax expense (benefit) is as follows:

The components of deferred income tax assets (liabilities) are as follows:

The Company regularly assesses its ability to realize its deferred tax assets. Assessing the realizability of deferred tax assets requires significant management judgment. In determining whether its deferred tax assets are more-likely-than-not realizable, the Company evaluated all available positive and negative evidence. As of December 31, 2024 and 2023, the Company maintains a valuation allowance of $15.6 million and $3.6 million, respectively. The amount in 2024 primarily related to unrealized losses incurred during the year on its investment in equity securities and to net deferred tax assets of certain of the Company’s foreign subsidiaries. The 2023 amount only relates to the net deferred tax assets of certain of the Company’s foreign subsidiaries.

Utilization of net operating loss carryforwards and research and development credit carryforwards may be subject to a substantial annual limitation due to ownership change limitations that could occur in the future in accordance with Section 382 of the Internal Revenue Code of 1986 (“IRC Section 382”) and with Section 383 of the Internal Revenue Code of 1986, as well as similar state provisions. These ownership changes may limit the amount of net operating loss carryforwards and research and development credit carryforwards that can be utilized annually to offset future taxable income and taxes, respectively. In general, an ownership change, as defined by IRC Section 382, results from transactions which impact the ownership of certain stockholders or public groups in the stock of a corporation by more than 50 percentage points over a three-year period.

At December 31, 2024, the Company had U.S. federal net operating loss carryforwards of approximately $269.9 million, $128.1 million of which will expire between 2027 and 2037, and $141.8 million of which can be carried forward indefinitely. The Company has foreign net operating losses of $29.0 million and $4.3 million which expire in 2035 and $24.7 million of which can be carried forward indefinitely. The Company’s state net operating losses are $9.1 million on a tax-effected basis, which will expire between 2025 and 2044. The Company has state research credit carryforwards of $2.1 million, which will expire between 2026 and 2039.

The Company’s U.S. federal income tax returns are subject to examination for three years after the filing date of the return. The state and foreign income tax returns are subject to examination for periods varying from three to four years after filing, depending on the specific jurisdiction’s statutes of limitation, and in the case of Sweden, up to six years after the end of the financial year.

A reconciliation of the Company’s changes in uncertain tax positions for 2024 and 2023 is as follows:

In connection with the Company’s acquisition of the medical imaging business from Bristol Myers Squibb (“BMS”) in 2008, the Company recorded a liability for uncertain tax positions related to the acquired business and simultaneously entered into an indemnification agreement with BMS for any payments made to settle those uncertain tax positions with the taxing authorities.

In accordance with the Company’s accounting policy, the change in the tax liability, penalties and interest associated with these obligations (net of any offsetting federal or state benefit) is recognized within income tax expense. 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 the Company, there will be no effect on net income and no net cash outflows related to these liabilities. Included in other (income) loss for the years ended December 31, 2024, 2023 and 2022, is tax indemnification (income) expense, net of ($0.1) million, $4.9 million and $9.6 million, respectively.

As of December 31, 2024 and 2023, total liabilities for uncertain tax positions including interest and penalties were $9.4 million and $5.4 million, respectively, consisting of uncertain tax positions of $7.6 million and $4.1 million, respectively, interest accruals of $1.8 million and $1.3 million, respectively, andno penalty accruals as of December 31, 2024 and 2023. The increase in uncertain tax positions during the year ended December 31, 2024 was primarily related to state tax uncertainties. As of December 31, 2024, $1.4 million, $7.3 million, and $0.7 million of these liabilities were recorded in current liabilities, other long-term liabilities, and as a reduction of deferred tax assets, respectively. As of December 31, 2023, $1.3 million, $3.2 million and $0.9 million of these liabilities were recorded in current liabilities, other long-term liabilities, and as a reduction of deferred tax assets, respectively. Included in the 2024 tax provision are expenses of $2.5 million, primarily related to state tax position. Included in the 2023 and 2022 tax provision are benefits of $5.0 million and $12.6 million, respectively, relating to reversals of uncertain tax positions recognized upon settlements, effective settlements, or lapses of relevant statutes of limitation, partially offset by interest accruals. As of December 31, 2024, the Company has $5.7 million of unrecognized tax benefits which would impact the effective tax rate if recognized.

6. Inventory

Inventory consisted of the following:

The Company has no inventory pending regulatory approval as of December 31, 2024 and 2023. The majority of the value of the inventory relates to non-radioactive products. With respect to the Company’s products that are radiopharmaceuticals, due to the limited shelf life of such products, they are generally not held as finished goods.

7. Property, Plant and Equipment, Net

Property, plant and equipment, net, consisted of the following:

Depreciation and amortization expense related to property, plant & equipment, net, was $20.4 million, $13.2 million and $13.7 million for the years ended December 31, 2024, 2023 and 2022, respectively.

The Company tests 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.

During 2023, as a result of a decline in expected future cash flows related to the AZEDRA marketed intangible asset, the Company determined certain impairment triggers had occurred. Subsequently, in 2023, the Company discontinued the production and promotion of AZEDRA and decided to wind down its facility at 110 Clyde Rd, Somerset, New Jersey (the “Somerset Facility”). The Company reviewed revised undiscounted cash flows that were estimated to be generated by the asset group as of June 30, 2023. Based on the undiscounted cash flow analysis, the Company determined that the asset group had net carrying values that exceeded their estimated undiscounted future cash flows. The Company then estimated the fair value of the asset group based on their discounted cash flows. The carrying value exceeded the fair value and as a result, the Company recorded a noncash impairment of $6.0 million during 2023 in cost of goods sold in the consolidated statement of operations.

On January 8, 2024, the Company entered into an agreement with Perspective to transfer the sublease for the Somerset Facility and sold the associated assets at the Somerset Facility for $8.0 million. The transfer of the sublease and completion of the asset sale occurred on March 1, 2024. The sale of assets resulted in a derecognition to the right-of-use asset of $0.4 million, the lease liability of $0.4 million and remaining property, plant and equipment of $0.8 million. The Company also incurred commission expense of $1.0 million related to the transaction. The Company recorded a gain on sale of assets of $6.3 million for the year ended December 31, 2024.

8. Sale of Portion of North Billerica Facility

During the first quarter of 2023, the Company committed to a plan to sell a then-unused portion of its land and buildings associated with its North Billerica campus. Effective March 16, 2023, the Company entered into a purchase and sale agreement with a prospective buyer and the sale of that portion of the North Billerica campus was completed in December 2024. The assets were classified as held for sale and comprised entirely of property, plant and equipment, net. The Company determined that the fair value of the net assets being sold exceeded the carrying value as of September 30, 2023. The purchase price for the sold portion of the North Billerica campus was $9.8 million in cash. As a result of the sale on December 10, 2024, the Company recorded a gain on sale of assets of $2.1 million in their consolidated statements of operations for the year ended December 31, 2024.

9. Asset Retirement Obligations

The Company considers its legal obligation to remediate its facilities upon a decommissioning of its radioactive-related operations as an asset retirement obligation. The Company has production facilities which manufacture and process radioactive materials at its sites in North Billerica, Massachusetts and, through March 1, 2024, Somerset, New Jersey. As of December 31, 2024, the asset retirement liability is measured at the present value of the asset retirement liability expected to be incurred, and is approximately $25.1 million.

The following table provides a summary of the changes in the Company’s carrying value of asset retirement obligations:

The Company is required to provide the Massachusetts Department of Public Health financial assurance demonstrating the Company’s ability to fund the decommissioning and decontaminating of its North Billerica, Massachusetts facility in the event of any closure. The Company has provided this financial assurance in the form of a $30.3 million surety bond.

10. Intangibles, Net and Goodwill

Intangibles, net, consisted of the following:

The Company recorded amortization expense for its intangible assets of $43.8 million, $46.4 million and $33.2 million for the years ended December 31, 2024, 2023 and 2022, respectively.

In March 2023, the Company stopped all development activities in relation to a future indication associated with AZEDRA, which was classified as an 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. The Company recorded a non-cash impairment charge of $15.6 million inresearch and development expenses relating to the IPR&D asset and $116.4 million incost of goods sold relating to the currently marketed indication of AZEDRA in the consolidated statement of operations for the quarter ended March 31, 2023.

On August 2, 2023, the Company sold the right to its RELISTOR royalty asset under its license agreement with Bausch; the Company retained the rights to future sales-based milestone payments. The Company received an initial payment of approximately $98.0 million in connection with the sale and has 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. No sales-based milestone payment was earned in 2024. During the fourth quarter of 2023, the Company earned a sales-based milestone payment of $15.0 million.

On August 15, 2023, the Company announced that it would discontinue the production and promotion of AZEDRA and would be winding down its Somerset Facility. The Company continued manufacturing AZEDRA until the first quarter of 2024 to provide doses of AZEDRA to then-current patients so they could complete their treatment regimen. No AZEDRA was manufactured after March 1, 2024, when the Company transferred the tangible assets and associated lease of its Somerset Facility to Perspective. See Note 7,“Property, Plant and Equipment, Net”to these consolidated financial statements for impairment analysis.

In February 2023, the Company entered into an agreement with the stockholders of Cerveau Technologies, Inc. (“Cerveau”) to purchase all of the outstanding capital stock of Cerveau for approximately $35.3 million. In May 2023, upon successful completion of a technology transfer, the Company paid $10.0 million to the selling stockholders of Cerveau. This additional contingent payment was capitalized as part of the asset cost and increased the Company’s customer relationship intangible assets. See Note 21,“Acquisition of Assets” to these consolidated financial statements for further discussion of the Company’s acquisition of Cerveau.

In June 2024, the Company entered into an agreement with the stockholders of Meilleur (“Meilleur Stockholders”) to purchase all of the outstanding capital stock of Meilleur (which holds the rights under a license agreement to develop and commercialize NAV-4694) for approximately $32.9 million. The Company recorded a developed technology intangible asset of $40.3 million as a result of the purchase price and the specific assets and liabilities of Meilleur that were acquired as part of the asset acquisition based on their value at the agreed upon closing date. In August 2024, upon successful completion of a technology transfer, the Company paid $10.0 million to the Meilleur Stockholders. This additional contingent payment was capitalized as part of the asset cost and increased the total value of the Company’s developed technology intangible assets. See Note 21,“Acquisition of Assets” to these consolidated financial statements for further discussion of the acquisition of Meilleur.

The below table summarizes the estimated aggregate amortization expense expected to be recognized on the above intangible assets:

11. Accrued Expenses and Other Liabilities and Other Long-Term Liabilities

Accrued expenses and other liabilities and other long-term liabilities are comprised of the following:

12. Long-Term Debt, Net, and Other Borrowings

As of December 31, 2024, the Company’s maturities of principal obligations under its long-term debt and other borrowings are as follows:

2022 Revolving Facility

In December 2024, the Company entered into an amendment to its $350.0 million five-year revolving credit facility, which, among other things, increased the facility from $350.0 million to $750.0 million (as amended, the “2022 Revolving Facility”) and extended the maturity date from December 2, 2027 to December 19, 2029. Under the terms of the 2022 Revolving Facility, the lenders are committed to extending credit to the Company from time to time consisting of revolving loans (the “Revolving Loans”) in an aggregate principal amount not to exceed $750.0 million (the “Revolving Commitment”) at any time, including a $40.0 million sub-facility for the issuance of letters of credit (the “Letters of Credit”) and a $20.0 million sub-facility for swingline loans (the “Swingline Loans”). The Revolving Loans, Letters of Credit, and the Swingline Loans, if used, are expected to be used for working capital and for other general corporate purposes.

The Revolving Loans bear interest, with pricing based from time to time at the Company’s election, at (i) the secured overnight financing rate as published by the Federal Reserve Bank of New York on its website plus an applicable margin that ranges from 1.25% to 2.00% based on the Company’s total net leverage ratio or (ii) the alternative base rate plus an applicable margin that ranges from 0.25% to 1.00%, in either case, based on the Company’s total net leverage ratio. The 2022 Revolving Facility also includes an unused commitment fee at a rate ranging from 0.15% to 0.30% per annum based on the Company’s total net leverage ratio. Interest associated with the unused commitment is recorded to accrued expenses and other liabilities on the consolidated balance sheet and paid out on a quarterly basis.

The Company is permitted to voluntarily prepay the Revolving Loans, in whole or in part, or reduce or terminate the Revolving Commitment, in each case, without premium or penalty. On any business day on which the total amount of outstanding Revolving Loans, Letters of Credit and Swingline Loans exceeds the total Revolving Commitment, the Company must prepay the Revolving Loans in an amount equal to such excess. The Company is not required to make mandatory prepayments under the 2022 Revolving Facility. As of December 31, 2024, there wereno outstanding borrowings under the 2022 Revolving Facility.

The Company has the right to request an increase to the Revolving Commitment in an aggregate principal amount of up to the greater of the sum of $685.0 million (so that the total amount available is $1.44 billion) or 100% of consolidated earnings before interest, taxes, depreciation and amortization for the four consecutive fiscal quarters most recently ended, plus additional amounts in certain circumstances (collectively, the “Incremental Cap”), minus certain incremental term loans made pursuant to specified incremental term loan commitments (“Incremental Term Loans”). The Company has the right to request Incremental Term Loans in an aggregate principal amount of up to the Incremental Cap less any incremental increases to the Revolving Commitment. Proceeds of Incremental Term Loans may be used for working capital and for other general corporate purposes and will bear interest at rates agreed between the Company and the lenders providing the Incremental Term Loans.

2022 Revolving Facility Covenants

The 2022 Revolving Facility contains a number of affirmative, negative and reporting covenants, as well as financial maintenance covenants pursuant to which the Company is required to be in quarterly compliance, measured on a trailing four quarter basis, withtwo financial covenants. The minimum interest coverage ratio must be at least 3.00 to 1.00. The maximum total net leverage ratio permitted by the financial covenant is 3.50 to 1.00, other than in connection with certain acquisitions, in which case, the maximum total net leverage ratio permitted can be increased to 4.00 to 1.00.

The 2022 Revolving Facility contains usual and customary restrictions on the ability of the Company and its subsidiaries to: (i) incur additional indebtedness (ii) create liens; (iii) consolidate, merge, sell or otherwise dispose of all or substantially all of its assets; (iv) sell certain assets; (v) pay dividends on, repurchase or make distributions in respect of capital stock or make other restricted payments; (vi) make certain investments; (vii) repay subordinated indebtedness prior to stated maturity; and (viii) enter into certain transactions with its affiliates.

Upon an event of default, the Administrative Agent will have the right to declare the loans and other obligations outstanding under the 2022 Revolving Facility immediately due and payable and all commitments immediately terminated.

The 2022 Revolving Facility is guaranteed by Lantheus Holdings, and certain subsidiaries of LMI, including Progenics and Lantheus Real Estate, and obligations under the 2022 Revolving Facility are generally secured by first priority liens over substantially all of the assets of each of LMI, Lantheus Holdings, and certain subsidiaries of LMI, including Progenics and Lantheus MI Real Estate (subject to customary exclusions set forth in the transaction documents) owned as of December 2, 2022 or thereafter acquired.

2.625% Convertible Senior Notes due 2027

On December 8, 2022, the Company 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 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 (the “Guarantor”), a wholly owned subsidiary of the Company, as Guarantor, and U.S. Bank Trust Company, National Association, 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 the Company.

The Notes are senior unsecured obligations of the Company. The Notes are fully and unconditionally guaranteed on a senior unsecured basis by the Guarantor. The Notes bear interest at a rate of 2.625% per year, payable semi-annually in arrears on June 15 and December 15 of each year, beginning on June 15, 2023, and will mature on December 15, 2027 unless earlier redeemed, repurchased or converted in accordance with their terms. The initial conversion rate for the Notes is 12.5291 shares of the Company’s common stock per $1,000 in principal amount of Notes (which is equivalent to an initial conversion price of approximately $79.81 per share of the Company’s common stock, representing an initial conversion premium of approximately 42.5% above the closing price of $56.01 per share of the Company’s common stock on December 5, 2022). In no event shall the conversation rate per $1,000 in principal amount of notes exceed 17.8539 shares of the Company’s common stock. 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 only 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. The Company will satisfy any conversion by paying cash up to the aggregate principal amount of the Notes to be converted and by paying or delivering, as the case may be, cash, shares of the Company’s common stock, or a combination of cash and shares of the Company’s common stock, at its election, in respect of the remainder, if any, of its conversion obligation in excess of the aggregate principal amount of the Notes being converted. The Company may redeem for cash all or any portion of the Notes, at its option, on or after December 22, 2025 if the closing sale price per share of the Company’s common stock exceeds 130% of the conversion price of the Notes for a specified period of time. The redemption price will be equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the redemption date.

The Company evaluated the Notes upon completion of the sale and concluded on the following features:

•Conversion Feature: The Company determined that the conversion feature qualifies for the classification of equity. As a result, the conversion feature should not be bifurcated as a derivative instrument and the Notes were accounted for as a single liability.

•Redemption Features: The redemption features were reviewed within the Notes and the Company determined that the redemption features are closely related to the Notes and as such should not be separately accounted for as a bifurcated derivative instrument.

•Additional Interest Features: The Notes may result in additional interest if the Company fails to timely file any document or report that the Company is required to file with the SEC pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934. The Company will pay additional interest on the notes at a rate equal to 0.25% to 0.50% per annum based on the principal amount of notes outstanding for each day the Company failure to file has occurred or the notes are not otherwise freely tradable. Further, if the notes are assigned a restricted CUSIP number or the notes are not otherwise freely tradable pursuant to Rule 144 under the Securities Act of 1933, as amended, by holders other than our affiliates or holders that were our affiliates at any time during the three months immediately preceding as of the 385 th day after the last date of original issuance of the notes offered hereby, the Company will pay additional interest on the notes at a rate equal to (i)0.25% to 0.50% per annum based on the principal amount of notes outstanding for each day until the restrictive legend has been removed from the notes, the notes are assigned an unrestricted CUSIP and the notes are freely tradable. The Company concluded that the interest feature is unrelated to the credit risk and should be bifurcated from the Notes, however, the Company assessed the probabilities of triggering events occurring under these features and does not expect to trigger the aforementioned events. These events will continue to be monitored to determine whether the interest feature will be bifurcated if it has value.

Holders of the Notes may require the Company to repurchase their Notes upon the occurrence of a fundamental change prior to the maturity at a repurchase price equal to 100% of the principal amount thereof, plus accrued and unpaid interest to, but excluding, the date of repurchase. In connection with certain triggering events, the Company will, under certain circumstances, increase the conversion rate for holders of the Notes who elect to convert their Notes in connection with such corporate events.

During the fourth quarter of 2024, the closing price of the Company’s common stock did not exceed 130% of the conversion price of the Notes for more than 20 trading days of the last 30 consecutive trading days of the quarter. As a result, the Notes are not convertible at the option of the holders of the Notes during the first quarter of 2024, the quarter immediately following the quarter when the conditions are met, as stated in the terms of the Notes. Because the Notes are not considered convertible under the terms of the Notes and pursuant to ASC 470-10, the Company classified the carrying value of the Notes as long-term debt, net and other borrowings on the Company’s consolidated balance sheet as of December 31, 2024.

The Company recorded interest expense of approximately $15.1 million related to the Notes for the year ended December 31, 2024.

13. Derivative Instruments

The Company has used, but does not currently use, interest rate swaps to reduce the variability in cash flows associated with a portion of the Company’s forecasted interest payments on its variable rate debt.

14. Accumulated Other Comprehensive Loss

The components of Accumulated Other Comprehensive Loss, net of tax effects for the years ended December 31, 2024 and 2023, consisted of the following:

(1)For purposes of comprehensive income disclosures, we do not record tax expense or benefits for the net changes in the foreign currency translation adjustments.

15. Stock-Based Compensation

Equity Incentive Plans

As of December 31, 2024, the Company’s approved equity incentive plans included the 2015 Equity Incentive Plan (“2015 Plan”), the 2013 Equity Incentive Plan (“2013 Plan”), and the 2008 Equity Incentive Plan (“2008 Plan”). These plans are administered by the Board of Directors (the “Board”) and permit the granting of stock, stock options, stock appreciation rights, restricted stock, restricted stock units and dividend equivalent rights to employees, officers, directors and consultants of the Company.

The Company has certain stock option and restricted stock awards outstanding under each of its equity incentive plans but, upon adoption of the 2015 Plan, the Company no longer grants new equity awards under its 2008 and 2013 Plans. The Company adopted its 2015 Plan in June 2015 and subsequently amended the plan in April 2016, 2017, 2019, 2021, 2022 and 2024 and again in October 2024. The amended plans increased the common stock reserved for issuance under the 2015 Plan to an aggregate 14,930,277 shares. The Company assumed Progenics equity plans due to the acquisition as discussed in Note 1,“Description of Business” to these consolidated financial statements. The Company no longer grants new equity awards under the Progenics equity plans.

Stock-based compensation expense recognized in the consolidated statements of operations is summarized below:

Stock Options

Stock option awards under the 2015 Plan are granted with an exercise price equal to the fair value of the Company’s common stock at the date of grant. All option awards have aten-year contractual term.

A summary of option activity for 2024 is presented below:

The table below summarizes the key weighted-average assumptions used in valuing stock options granted:

During the years ended December 31, 2024, 2023 and 2022,209,657,214,619 and 397,822 options were exercised having aggregate intrinsic values of $12.1 million, $12.9 million and $13.1 million, respectively. The weighted average grant-date fair value of stock options granted was $39.26 for the year ended December 31, 2024.

As of December 31, 2024, there was $19.7 million of unrecognized compensation expense related to outstanding stock options, which is expected to be recognized over a weighted-average period of 2.0 years.

Restricted Stock Units

A summary of restricted stock awards and restricted stock units (“RSUs”) activity for 2024 is presented below:

Restricted stock generally vest over 3 years. As of December 31, 2024, there was $58.4 million of unrecognized compensation expense related to outstanding restricted stock, which is expected to be recognized over a weighted-average period of 1.9 years.

The weighted average grant-date fair value for restricted stock granted during the fiscal years ended December 31, 2024, 2023 and 2022 was $70.56, $74.38 and $51.51 per share, respectively. The total fair value of restricted stock vested in fiscal years 2024, 2023 and 2022 was $42.5 million, $18.3 million and $11.9 million, respectively.

Total Stockholder Return Restricted Stock Awards

During the years ended December 31, 2024, 2023 and 2022, the Company granted total stockholder return (“TSR”) awards that include athree-year market condition where the performance measurement period isthree years. Vesting of the TSR awards is based on the Company’s level of attainment of specified TSR targets relative to the percentage appreciation of a specified index of companies for the respective three-year period and is also subject to the continued employment of the grantees. The number of shares that are earned over the performance period ranges from 0% to 200% of the initial award. The fair value of these awards are based on a Monte Carlo simulation valuation model with the following assumptions:

A summary of TSR award activity for 2024 is presented below:

As of December 31, 2024, there was $35.4 million of unrecognized compensation expense related to outstanding performance restricted stock which is expected to be recognized over a weighted-average period of 1.9 years.

The weighted average grant-date fair value for TSR awards granted during the fiscal years ended December 31, 2024, 2023 and 2022 was $105.87, $127.75 and $95.31 per share, respectively. The total fair value of TSR awards vested in fiscal years 2024, 2023 and 2022 was $33.6 million, $8.2 million and $8.8 million, respectively.

Modification of equity awards

In the fourth quarter of 2024, as part of the Company’s evolution into a fully integrated radiopharmaceutical company, the Company reviewed its current capabilities and skillsets and began implementing organizational changes deemed necessary to best position the Company to execute on its long-term strategy. These changes include transitioning approximately 60 employees out of the Company. In connection with these changes, the Company approved equity modifications that allowed grants of stock options and RSUs issued to those impacted by this event to continue to vest in 2024 and 2025 with any unvested stock option and RSU grants as of December 31, 2025 to be cancelled. TSR awards granted to these individuals will continue to vest on their original vesting schedule but any shares issued will be issued in a pro-rated amount based on the time served during the performance period. The incremental stock-based compensation expense resulting from these modifications recognized in 2024 was $2.7 million. Total costs related to these organizational changes through December 31, 2024 were approximately $9.4 million. Remaining costs expected to be incurred are not material.

Common Stock Repurchases

In November 2024, the Board authorized a program to repurchase up to $250 million of the Company’s common stock over the next twelve months (the “2024 Program”). Such repurchases may be made from time to time via open market purchases at prevailing market prices, in privately negotiated transactions, block trades, or pursuant to trades intending to comply with Rule 10b5-1 under the Securities Exchange Act of 1934, as amended or through other legally permissible means, depending on market conditions and in accordance with applicable rules and regulations. The actual timing, number and dollar amount of repurchase transactions will be determined by our management, in its discretion and will depend on a number of factors, including but not limited to, the market price of the Company’s common stock. In the year ended December 31, 2024, the Company repurchased approximately 1.1 million shares of its outstanding common stock under the 2024 Program for an aggregate purchase price of approximately $100.0 million at an average stock price of $89.59 per share.

16. Leases

The Company determines if an arrangement is a lease at inception. The Company has operating and finance leases for vehicles, corporate offices and certain equipment.

Operating lease right-of-use (“ROU”) assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. Lease agreements with lease and non-lease components are accounted for separately. As the Company’s leases do not provide an implicit rate, the Company used the incremental borrowing rate based on the information available at commencement date in determining the present value of future payments. The operating lease ROU asset also includes any lease payments made and excludes lease incentives and initial direct costs incurred. The lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term.

The Company assumedtwo operating leases as a result of the Progenics acquisition related to office space at the World Trade Center in New York City, pursuant to a lease agreement expiring in September 2030 (the “WTC Lease”), and a radiopharmaceutical manufacturing facility in Somerset, New Jersey, under a sublease agreement expiring in November 2028, which were recorded as of June 19, 2020, for $18.6 million and $0.6 million, respectively. The Company entered into an operating lease related to office space in Somerset, New Jersey, under a lease agreement expiring in August 2026, which was recorded in October 2021 for $0.7 million. The Company entered into an operating lease agreement in February 2022 to lease office space in Bedford, Massachusetts (“Existing Premises”), under a lease agreement expiring in June 2031, which commenced and was recorded in December 2022 for $11.0 million (the “Existing Premises Lease”).

On May 4, 2023, the Company entered into a modification to the Existing Premises Lease. The lease modification includes a lease of additional office and laboratory space at the Bedford location (the “Additional Premises”) for a term of 15 years and 4 months and extends the term of the lease for the Existing Premises to be coterminous with the term of the lease for the Additional Premises. As a result of the extended term for the Existing Premises, the Company recorded an additional right-of-use asset and liability of $6.0 million in May 2023. The modification also contains a provision to convert the rent schedule of the Existing Premises from gross to triple net in 2025, which may result in an additional adjustment to the right-of-use asset and liability. In September 2023, the landlord provided notice to the Company that its renovations of the Additional Premises were completed. As a result of the notice, the Company recorded an additional right-of-use asset and liability of $23.5 million as of September 1, 2023. To determine the value of the additional right-of-use asset and liability, the Company was required to calculate the discount rate of the lease modification. The discount rate was determined based on the expected lease term and by comparing interest rates in the market for similar borrowings with comparable credit quality of the Company. The lease for the Additional Premises allows for the extension offive years to begin immediately upon the expiration of the original term. On October 7, 2024, the Company executed a second amendment to the Bedford Lease for additional space resulting in one additional operating lease. As of December 31, 2024, the additional operating lease has not yet commenced. The future lease payments for this lease are approximately $17.0 million. The lease is expected to commence in 2026 and has a noncancellable lease term of 13.3 years.

On March 1, 2024, the Company transferred the sublease and completed the asset sale of the Somerset Facility. See Note 7,“Property, Plan and Equipment, Net” to these consolidated financial statements for further discussion on the sublease transfer.

Leases with an initial term of 12 months or less are not recorded on the balance sheet as the Company has elected to apply the short-term lease exemption. The Company recognizes lease expense for these leases on a straight-line basis over the lease term.

Operating and finance lease assets and liabilities are as follows:

The components of lease expense were as follows:

Other information related to leases were as follows:

Future minimum lease payments under non-cancellable leases as of December 31, 2024 were as follows:

17. Other Assets

Other assets are comprised of the following:

18. Net Income Per Common Share

A summary of net income per common share is presented below:

Impact of the Convertible Notes

The Company considered whether the notes are participating securities through the two-class method. Per the terms of the indenture governing the Notes’, the Company determined that if a cash dividend is paid that is greater than the then stock price, the holder of Notes will receive cash on an if-converted basis. While this feature is considered to be a participating right; basic earnings per share is only impacted if the Company’s earning exceeds the current share price, regardless of whether such dividend is declared. During the year ended December 31, 2024, no such dividend was declared. In addition, the Company is required to settle the principal amount of the Notes in cash upon conversion, and therefore, the Company uses the if-converted method for calculating any potential dilutive effect of the conversion option on diluted net income per share, if applicable, unless the application of the two-class method is dilutive. The conversion option will have a dilutive impact on net income per share of Common Stock when the average price per share of the Company’s Common Stock for a given period exceeds the conversion price of the Notes of $79.81 per share. See Note 12,“Long-Term Debt, Net, and Other Borrowings,”to these consolidated financial statementsfor further discussion on the Notes.

19. Commitments and Contingencies

Purchase Commitments

The Company has entered into purchasing arrangements in which minimum quantities of goods or services have been committed to be purchased on an annual basis.

As of December 31, 2024, future payments required under purchase commitments are as follows:

The Company has entered into agreements which contain certain percentage volume purchase requirements. The Company has excluded these future purchase commitments from the table above since there are no minimum purchase commitments or payments under these agreements.

License Agreements

The Company has entered into license agreements in which fixed payments have been committed to be paid on an annual basis.

As of December 31, 2024, no future fixed payments are required under license agreements. The Company may be required to pay approximately $3.7 billion in contingent payments under the Company’s license agreements. These contingent payments include potential milestone or contractual payment obligations contingent upon the achievement or occurrence of future milestones or events and the amounts and timing of such potential obligations are unknown or uncertain.

Legal Proceedings

From time to time, the Company is a party to various legal proceedings arising in the ordinary course of business. In addition, the Company has in the past been, and may in the future be, subject to investigations by governmental and regulatory authorities, which expose it to greater risks associated with litigation, regulatory or other proceedings, as a result of which the Company could be required to pay significant fines or penalties. The costs and outcome of litigation, regulatory or other proceedings cannot be predicted with certainty, and some lawsuits, claims, actions or proceedings may be disposed of unfavorably to the Company and could have a material adverse effect on the Company’s results of operations or financial condition. In addition, intellectual property disputes often have a risk of injunctive relief which, if imposed against the Company, could materially and adversely affect its financial condition or results of operations. If a matter is both probable to result in material liability and the amount of loss can be reasonably estimated, the Company estimates and discloses the possible material loss or range of loss. If such loss is not probable or cannot be reasonably estimated, a liability is not recorded in its consolidated financial statements.

As of December 31, 2024, the Company did not have any material ongoing litigation to which the Company was a party. On January 26, 2024, the Company was 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 Abbreviated New Drug Application and Paragraph IV certification in connection with PNT2003, consistent with the process established by the Hatch-Waxman Act. Because the outcome of litigation is uncertain, the Company cannot predict how or when this matter will ultimately be resolved.

On February 23, 2024, the Company filed a patent infringement lawsuit against a healthcare-related imaging software developer, and that developer filed a motion to dismiss the case based on grounds of invalidity for certain patents and failure to state a claim for infringement for other patents. The court dismissed the developer’s motion to dismiss as to invalidity, and granted the motion as to certain allegations of infringement. Because the outcome of litigation is uncertain, the Company cannot predict how or when this matter will ultimately be resolved.

20.401(k) Plan

The Company maintains a qualified 401(k) plan (the “401(k) Plan”) for its U.S. employees. The 401(k) Plan covers U.S. employees who meet certain eligibility requirements. Under the terms of the 401(k) Plan, the employees may elect to make tax-deferred contributions through payroll deductions within statutory and plan limits, and the Company may elect to make non-elective discretionary contributions. The Company may also make optional contributions to the 401(k) Plan for any plan year at its discretion.

Expense recognized by the Company for matching contributions made to the 401(k) Plan was $5.8 million, $4.1 million, and $3.1 million for the years ended December 31, 2024, 2022 and 2021, respectively.

21. Acquisition of Assets

In December 2022, the Company made upfront payments of $260.0 million to POINT Biopharma Global Inc. (“POINT”) as a part of an asset acquisition with the potential for additional milestone payments of approximately $1.8 billion between the two licensed assets based on U.S. Food and Drug Administration (“FDA”) approval and net sales and commercial milestones.

Under the terms of the PNT2002 License Agreement, the Company 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.

Under the terms of the PNT2003 License Agreement, the Company 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.

Additionally, the Company will pay POINT royalties on net sales, beyond certain financial thresholds and subject to conditions, of 20% for PNT2002 and 15% for PNT2003. Costs of IPR&D projects acquired as part of an asset acquisition that have no alternative future use are expensed when incurred, and therefore, a charge of $260.0 million was recognized in research and development expenses during the year ended December 31, 2022.

On February 6, 2023, the Company acquired Cerveau. Cerveau holds the rights under a license agreement to develop and commercialize MK-6240, an investigational late-stage F-18-labeled PET imaging agent that targets tau tangles in Alzheimer’s disease. The Company determined that upon review of its acquisition of Cerveau, the transaction did not meet the definition of a business combination and is therefore treated as an asset acquisition.

In February 2023, the Company made an upfront payment of approximately $35.3 million to the stockholders of Cerveau (the “Cerveau Stockholders”) and paid the Cerveau 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 Cerveau 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, 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 Cerveau Stockholders up to double-digit royalty payments for research revenue and commercial sales. Research revenue is derived from existing partnerships with pharmaceutical companies and academic institutions that use MK-6240 in clinical trials. The purchase agreement pursuant to which the Company purchased Cerveau specified, among other things, that certain Cerveau Stockholders provide transition and clinical development services for a prescribed time following the closing of the transaction.

On January 8, 2024, the Company entered into an agreement with Perspective to participate in the next qualified financing to purchase the shares of Perspective common stock (“Perspective Shares”). On January 22, 2024, the Company purchased 56,342,355 Perspective Shares, representing 11.39% of the outstanding Perspective Shares, at the fair market offering price of $0.37 per share. Included within the agreement is a covenant which allows for the Company to designate one observer to Perspective’s board of directors. The observer has the option to attend any or all board meetings in a nonvoting capacity and the right to receive any board materials, except under certain instances where attorney-client privilege is necessary, where the material relates to a business or contractual relationship with the Company, to avoid bona fide conflict of interest, exposure of trade secrets or relating to a change of control transaction. The Company also purchased 60,431,039 Perspective Shares at a fair market purchase price of $0.95 per share as an investor in a private placement transaction on March 6, 2024, which resulted in the Company holding a cumulative 19.90% of the outstanding Perspective Shares (or 17.35% on a fully diluted basis) after giving effect to the closing of the private placement transaction. The Company holds less than 20% of the outstanding Perspective Shares and therefore does not have the ability to exercise significant influence over operating and financial policies of Perspective because the Company’s board observer has no voting rights and there is otherwise no participation in policy-making processes, no interchange of managerial personnel, and no sharing of technology between the Company and Perspective.

Also effective January 8, 2024, the Company obtained the following options and rights from Perspective for an aggregate upfront payment of $28.0 million in cash:

•An exclusive option from Perspective to negotiate for an exclusive license under the rights of Perspective and its affiliates to Perspective’s Pb212-VMT-⍺-NET, a clinical stage alpha therapy developed for the treatment of neuroendocrine tumors, to develop, manufacture, commercialize and otherwise exploit the VMT-α-NET Product.

•A right to co-fund the investigational new drug application (“IND”) enabling studies for early-stage therapeutic candidates targeting prostate-specific membrane antigen and gastrin releasing peptide receptor and, prior to IND filing, a right to negotiate for an exclusive license to such candidates.

•A right of first offer and last look protections for any third party merger and acquisition transactions involving Perspective for a twelve-month period.

None of these options and rights have been exercised as of December 31, 2024.

Costs of IPR&D projects acquired as part of an asset acquisition that have no alternative future use are expensed when incurred, and therefore, a charge of $28.0 million was recognized in research and development expenses during the first quarter of 2024.

Also effective January 8, 2024, the Company entered into an agreement with Perspective to transfer the Somerset Facility and the associated assets at the Somerset Facility for $8.0 million. The transfer of the sublease and completion of the asset sale occurred on March 1, 2024 at which time the Company had no further continuing legal obligations related to the lease. See Note 7,“Property, Plant and Equipment, Net”to these consolidated financial statements for additional details.

On June 14, 2024 Perspective effected a 1-for-10 reverse stock split, after which the Company held 11,677,339 shares of Perspective’s common stock.

On June 15, 2024, the Company entered into an agreement with Radiopharm to acquire all of Radiopharm’s rights totwo licensed preclinical assets for an upfront payment of $2.0 million. The Company acquired global exclusive rights to both an LRRC15-targeted monoclonal antibody (“LRRC15”) and to a Trophoblast cell surface antigen 2 (“TROP2”)-targeted nanobody. LRRC15 is a potential first-in-class, highly specific monoclonal antibody radio-conjugate with both Orphan Drug and Rare Pediatric Disease designations from the FDA for the treatment of osteosarcoma. The agent is designed to target the surrounding tumor micro-environment cells expressing the protein potentially treating a broad range of cancers. The TROP2-targeted nanobody radio-conjugate is designed to target TROP2, an intracellular calcium signal transducer that is overexpressed in various types of adenocarcinomas with minimal expression in normal tissues and is associated with tumor aggressiveness, poor prognosis and drug resistance.

In connection with this acquisition, the Company assumed the underlying license agreements related to the two preclinical assets, together with their respective milestone and royalty payment obligations. The Company could pay up to an additional $20.0 million in milestone payments upon achievement of specified regulatory milestones. The Company could also pay up to an additional $6.5 million in sales milestone payments upon the achievement of specified annual commercial sales thresholds in the event the Company pursues commercialization, as well as royalty payments for commercial sales. Costs of IPR&D projects acquired as part of an asset acquisition that have no alternative future use are expensed when incurred, and therefore, a charge of $2.0 million was recognized in research and development expenses during 2024 related to the Radiopharm transaction.

The Company also entered an agreement with Radiopharm to make an initial equity investment of approximately $5.0 million to purchase 149,625,180 Radiopharm shares (the “Initial Shares”) at the fair market offering price of $0.03 per share upon the receipt of required approvals from Radiopharm’s shareholders, which were obtained during the third quarter of 2024. Included within the agreement is an option for the Company to invest an additional $5.0 million within six months of the issuance date of the Initial Shares on the same terms as the Company’s initial purchase, which would result in the Company purchasing approximately an additional 149,925,040 Radiopharm shares. No additional shares were purchased under the option during the three months ended December 31, 2024.

On June 18, 2024, the Company acquired Meilleur, including its asset NAV-4694, an investigational F-18-labeled PET imaging agent that targets beta amyloids in Alzheimer’s disease. The Company determined that upon review of the Meilleur acquisition, the transaction did not meet the definition of a business combination and is therefore treated as an asset acquisition.

The Company made an upfront payment of approximately $32.9 million to the stockholders of Meilleur (“Meilleur Stockholders”) on June 18, 2024 and paid an additional $10.0 million in August 2024 after the successful completion of a technology transfer. The Company could pay up to an additional $43.0 million in milestone payments upon achievement of specified U.S. regulatory milestones related to NAV-4694. The Meilleur Stockholders are also eligible to receive up to $830.0 million in sales milestone payments upon the achievement of specified annual commercial sales thresholds of NAV-4694 as well as up to $4.0 million in remaining research milestones upon achievement of specified clinical studies at academic institutions thresholds. Research revenue is derived from existing partnerships with pharmaceutical companies and academic institutions that use NAV-4694 in clinical trials. Additionally, the Company could pay the Meilleur Stockholders up to double-digit royalty payments for research revenue and commercial sales.

On July 3, 2024, the Company acquired from Life Molecular Imaging Ltd. (“Life Molecular”) the global rights to RM2, a gastrin-releasing peptide receptor (“GRPR”)-targeting agent, including the associated novel, clinical-stage radiotherapeutic and radiodiagnostic pair, referred to as 177Lu-DOTA-RM2 and 68Ga-DOTA-RM2, for an upfront payment of $35.0 million plus a $1.0 million payment made prior to the acquisition. The Company could pay up to an additional 132.5 million Euros in regulatory milestone payments upon achievement of clinical trial thresholds and approvals in different regions. The Company could pay up to 280.0 million Euros in sales milestone payments upon the achievement of specified annual commercial sales threshold of RM2 in the event the Company pursues commercialization. Additionally, the Company could pay up to 25.0 million Euros for collaboration payments inclusive of all costs including employee costs, payments due to certain universities, out-of-pocket expenses and services costs, as well as up to 5.0 million Euros for any additional development services performed by Life Molecular through July 3, 2026.

Costs of IPR&D projects acquired as part of an asset acquisition that have no alternative future use are expensed when incurred, and therefore, a charge of $36.0 million was recognized in research and development expenses during 2024 related to the Life Molecular acquisition. Global rights are exclusive for therapeutic fields in all countries and diagnostic fields in the Americas and co-exclusive with Life Molecular for diagnostic fields outside of the Americas.

22. Segment Information

The Company operates asone business segment. The results of this operating segment are regularly reviewed by the Company’s chief operating decision maker (“CODM”), the Chief Executive Officer. The CODM does not manage any part of the Company separately, and the allocation of resources and assessment of performance are based on the Company’s consolidated operating results. In order to evaluate the reportable segment’s performance, the CODM uses net income and gross margin based on the consolidated statements of operations. The CODM uses net income to monitor budget and forecast versus actual results in assessing segment performance and to evaluate income generated from segment assets in deciding how to allocate resources. The measure of segment assets is reported on the consolidated balance sheets as total consolidated assets.

Significant segment expenses reviewed by the CODM on a monthly basis include sales and marketing, general and administrative and research and development expenses as reported in the Company’s consolidated statements of operations. However, the CODM reviews research and development expenses in more detail for certain expenses related to the Company’s development of new products and clinical programs. The approximate disaggregated amounts that comprise research and development expenses regularly reviewed by the CODM are as follows:

(1) Other research and development expenses consist of all other research and development costs incurred for the benefit of multiple research and development programs, including legal, employee costs, depreciation, information technology, other facility-bases expenses and other third-party costs.
