Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Business | Business We are a biopharmaceutical company enabling scientific advancement through supporting the clinical development of high-value medicines. We do this by providing financing, licensing our technologies or both.
Basis of Presentation and Principles of Consolidation | Basis of Presentation and Principles of Consolidation Our unaudited condensed consolidated financial statements include the financial statements of Ligand and its wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation. We have included all adjustments, consisting only of normal recurring adjustments, which we considered necessary for a fair presentation of our financial results. These unaudited condensed consolidated financial statements and accompanying notes should be read together with the audited consolidated financial statements included in our 2024 Annual Report. Interim financial results are not necessarily indicative of the results that may be expected for the full year.
Segment Information | Segment Information The Company has one operating and one reportable segment: development and licensing of biopharmaceutical assets. The Company's Chief Operating Decision Maker (“CODM”) is Todd Davis, our Chief Executive Officer. The CODM uses net income (loss) as a single segment profit or loss measure to evaluate our single segment performance, and in deciding whether to reinvest into the existing assets, or to new potential opportunities. Our CODM relies on internal management reporting processes that provide information on segment operating income (loss) for making financial decisions and allocating resources. The CODM does not evaluate, manage or measure performance of segments using asset information.
Reclassification | Reclassification Certain reclassification has been made to the previously issued audited consolidated financial statement to conform with the current period presentation. Specifically, within the consolidated balance sheet as of December 31, 2024, a portion of other current assets has been reclassified to short-term portion of financial royalty assets, net.
Use of Estimates | Use of Estimates The preparation of unaudited condensed consolidated financial statements in conformity with GAAP requires the use of estimates and assumptions that affect the amounts reported in the unaudited condensed consolidated financial statements and the accompanying notes. Actual results may differ from those estimates.
Revenue and Other Income | Revenue and Other Income Our revenue is generated primarily from royalties on sales of products commercialized by our partners, Captisol material sales, income from financial royalty assets, and contract revenue for license fees, technical, regulatory and sales-based milestone payments. Other operating income is primarily related to milestone income received for financial royalty assets that have been fully amortized or where there is no underlying asset recognized on the consolidated balance sheets. We apply the following five-step model in accordance with ASC 606, Revenue from Contracts with Customers, in order to determine the revenue: (i) identification of the promised goods or services in the contract; (ii) determination of whether the promised goods or services are performance obligations, including whether they are distinct in the context of the contract; (iii) measurement of the transaction price, including the constraint on variable consideration; (iv) allocation of the transaction price to the performance obligations; and (v) recognition of revenue when (or as) the Company satisfies each performance obligation. Revenue from Intangible Royalty Assets We receive royalty revenue from intangible royalty assets on sales by our partners of products covered by patents that we or our partners own under contractual agreements. We do not have future performance obligations under these license arrangements. We generally satisfy our obligation to grant intellectual property rights on the effective date of the contract. However, we apply the royalty recognition constraint required under the guidance for sales-based royalties which requires a royalty to be recorded no sooner than when the underlying sale occurs. Therefore, royalties on sales of products commercialized by our partners are recognized in the quarter the product is sold. Our partners generally report sales information to us on a one quarter lag. Thus, we estimate the expected royalty proceeds based on an analysis of historical experience and interim data provided by our partners including their publicly announced sales. Differences between actual and estimated royalty revenues, which have not been material, are adjusted in the period in which they become known, typically the following quarter. Income from Financial Royalty Assets We recognize income from financial royalty assets when there is a reasonable expectation about the timing and amount of cash flows expected to be collected. Income is calculated by multiplying the carrying value of the financial royalty asset by the periodic effective interest rate. We account for financial royalty assets related to developmental pipeline or recently commercialized products on a non-accrual basis. Developmental pipeline products are non-commercialized, non-approved products that require FDA or other regulatory approval, and thus have uncertain cash flows. Newly commercialized products typically do not have an established reliable sales pattern, and thus have uncertain cash flows. Captisol Sales Revenue from Captisol sales is recognized when control of Captisol material is transferred or intellectual property license rights are granted to our customers in an amount that reflects the consideration we expect to receive from our customers in exchange for those products or rights. A performance obligation is considered distinct from other obligations in a contract when it provides a benefit to the customer either on its own or together with other resources that are readily available to the customer and is separately identified in the contract. For Captisol material or intellectual property license rights, we consider our performance obligation satisfied once we have transferred control of the product or granted the intellectual property rights, meaning the customer has the ability to use and obtain the benefit of the Captisol material or intellectual property license right. We recognize revenue for satisfied performance obligations only when we determine there are no uncertainties regarding payment terms or transfer of control. Sales tax and other taxes we collect concurrent with revenue-producing activities are excluded from revenue. We have elected to recognize the cost of freight and shipping when control over Captisol material has transferred to the customer as an expense in cost of Captisol. We expense incremental costs of obtaining a contract when incurred if the expected amortization period of the asset that we would have recognized is one year or less or the amount is immaterial. We did not incur any incremental costs of obtaining a contract during the periods reported. Contract Revenue and Other Income Our contracts with customers often include variable consideration in the form of contingent milestone payments. We include contingent milestone payments in the estimated transaction price when it is probable a significant reversal in the amount of cumulative revenue recognized will not occur. These estimates are based on historical experience, anticipated results and our best judgment at the time. If the contingent milestone payment is based on sales, we apply the royalty recognition constraint and record revenue when the underlying sale has taken place. Significant judgments must be made in determining the transaction price for our sales of intellectual property. Because of the risk that products in development with our partners will not reach development milestones or receive regulatory approval, we generally recognize any contingent payments that would be due to us upon the development milestone or regulatory approval. Some customer contracts are sublicenses which require that we make payments to an upstream licensor related to license fees, milestones and royalties which we receive from customers. In such cases, we evaluate the determination of gross revenue as a principal versus net revenue as an agent reporting based on each individual agreement. Other income is primarily related to milestone income received for financial royalty assets that have been fully amortized or where there is no underlying asset recognized on the consolidated balance sheets. Deferred Revenue Depending on the terms of the arrangement, we may also defer a portion of the consideration received because we have to satisfy a future obligation. The timing of revenue recognition, billings and cash collections results in billed accounts receivable, unbilled receivables (contract assets), and customer advances and deposits (contract liabilities) on the consolidated balance sheet. Except for royalty revenue and certain service revenue, we generally receive payment at the point we satisfy our obligation or soon after. Any fees billed in advance of being earned are recorded as deferred revenue.
Short-term Investments | Short-term Investments Gain (loss) from short-term investments in our condensed consolidated statements of operations includes both realized and unrealized gain (loss) from our short-term investments in public equity and warrant securities. Allowances are recorded for available-for-sale debt securities with unrealized losses. This limits the amount of credit losses that can be recognized for available-for-sale debt securities to the amount by which carrying value exceeds fair value and requires the reversal of previously recognized credit losses if fair value increases. The provisions of the credit losses standard did not have a material impact on our available-for-sale debt securities during the three and six months ended June 30, 2025 and 2024. Our investment policy is capital preservation and we only invest in U.S.-dollar denominated investments.
Accounts Receivable and Allowance for Credit Losses | Accounts Receivable and Allowance for Credit Losses Our accounts receivable arise primarily from sales on credit to customers. We establish an allowance for credit losses to present the net amount of accounts receivable expected to be collected. The allowance is determined by using the loss-rate method, which requires an estimation of loss rates based upon historical loss experience adjusted for factors that are relevant to determining the expected collectability of accounts receivable. Some of these factors include macroeconomic conditions that correlate with historical loss experience, delinquency trends, aging behavior of receivables and credit and liquidity quality indicators for industry groups, customer classes or individual customers.
Inventory | Inventory Inventory, which consists of finished goods (Captisol), is stated at the lower of cost or net realizable value. We determine cost using the specific identification method. We analyze our inventory levels periodically and write down inventory to net realizable value if it has become obsolete, has a cost basis in excess of its expected net realizable value or is in excess of expected requirements.
Financial Royalty Assets, net | Financial Royalty Assets, net Financial royalty assets represent a portfolio of future milestone and royalty payment rights acquired that are passive in nature (i.e., we do not own the intellectual property or have the right to commercialize the underlying products). Although a financial royalty asset does not have the contractual terms typical of a loan (such as contractual principal and interest), we account for financial royalty assets under ASC 310, Receivables. Our financial royalty assets are classified similar to loans receivable and are measured at amortized cost using the prospective effective interest method described in ASC 835-30, Imputation of Interest. The effective interest rate is calculated by forecasting the expected cash flows to be received over the life of the asset relative to the initial invested amount. The effective interest rate is recalculated in each reporting period as the difference between expected cash flows and actual cash flows are realized and as there are changes to expected future cash flows. The gross carrying value of a financial royalty asset is made up of the opening balance, or net purchase price for a new financial royalty asset, which is increased by accrued interest income (except for assets under the non-accrual method) and decreased by cash receipts in the period to arrive at the ending balance. We evaluate financial royalty assets for recoverability on an individual basis by comparing the effective interest rate at each reporting date to that of the prior period. If the effective interest rate is lower for the current period than the prior period, and if the gross cash flows have declined (expected and collected), we record provision expense for the change in expected cash flows. The provision is measured as the difference between the financial royalty asset’s amortized cost basis and the net present value of the expected future cash flows, calculated using the prior period’s effective interest rate. In addition to the above allowance, we recognize an allowance for current expected credit losses under ASC 326, Financial Instruments – Credit Losses on our financial royalty assets. The credit rating, which is primarily based on publicly available data and updated quarterly, is the primary credit quality indicator used to determine the credit loss provision. The carrying value of financial royalty assets is presented net of the cumulative allowance for changes in expected future cash flows and expected credit losses. The initial amount and subsequent revisions in allowances for changes in expected future cash flows and expected credit losses are recorded as part of general and administrative expenses on the condensed consolidated statements of operations. When we are reasonably certain that a part of a financial royalty asset’s net carrying value (or all of it) is not recoverable, we recognize a permanent impairment which is recorded in financial royalty assets impairment on the condensed consolidated statements of operations. To the extent there was an allowance previously recorded for this asset, the amount of such impairment is written off against the allowance at the time that such a determination is made. Any future recoveries from such impairment are recognized when cash is collected in a respective period earnings. The current portion of financial royalty assets represents an estimation for current quarter royalty receipts which are collected during the subsequent quarter, net of the allowance for expected credit losses.
Research and Development Funding Expense | Research and Development Funding Expense We enter into transactions where we agree to fund a portion of the research and development (“R&D”) performed by our partners for products undergoing late-stage clinical trials in exchange for future royalties or milestones if the products are successfully developed and commercialized. In accordance with ASC 730, Research and Development, we account for the funded amounts as R&D expense when we have the ability to obtain the results of the R&D, the transfer of financial risk is genuine and substantive and, at the time of entering into the transaction, it is not yet probable that the product will receive regulatory approval. If these conditions are not met, we may record the funded amounts as a financial royalty asset. We may fund R&D upfront or over time as the underlying products undergo clinical trials. Royalties earned on successfully commercialized products generated from R&D arrangements are recognized as revenue from intangible royalty assets in the same period in which the sale of the commercialized product occurs. Fixed or milestone payments receivable based on the achievement of contractual criteria for products arising out of our R&D arrangements are recognized as contract revenue and other income in the period that the milestone threshold is met.
Derivative Assets | Derivative Assets Derivative assets include instruments used for risk-management purposes, and other instruments. Derivative assets which are not used for risk management purposes, include: (a) acquired rights in future milestone and royalty payments from Agenus Partnered Programs (as defined in Note 3, Castle Creek and Agenus Transactions), (b) rights to receive from Primrose Bio 50% of milestone payments on two contracts previously entered into by Primordial Genetics (“Primrose mRNA”), (c) Castle Creek Milestone (as defined in Note 3, Castle Creek and Agenus Transactions), (d) Agenus Warrant (as defined in Note 3, Castle Creek and Agenus Transactions), and (e) Castle Creek Warrant (as defined in Note 3, Castle Creek and Agenus Transactions). All derivatives are measured at fair value on the condensed consolidated balance sheets.
Equity Method Investment | Equity Method Investment Investments that we do not consolidate but in which we have significant influence over the operating and financial policies of the investee are classified as equity method investments and are accounted for using the equity method of accounting. In applying the equity method of accounting, investments are initially recorded at cost and are subsequently adjusted based on our proportionate share of net income or loss of the investee, net of any distributions received from the investee and any impairment. In connection with the sale of the Pelican business and investment in Primrose Bio transaction in September 2023, we account for our common stock investment in Primrose Bio under the equity method as we have the ability to exercise significant influence over Primrose Bio’s operating and financial results. Ligand owns 31.4% of the equity of Primrose Bio as of June 30, 2025 and December 31, 2024. Our proportionate share of net loss of Primrose Bio for the three and six months ended June 30, 2024 was $2.2 million and $4.6 million, respectively, and was recorded in other non-operating expense, net in the condensed consolidated statements of operations. As of December 31, 2024, equity method investment in Primrose Bio had been written down to zero, and we are not required to fund further losses from Primrose Bio. We have no outstanding advances, guarantees, or commitment to fund Primrose Bio’s losses; therefore, our proportionate share of net loss of Primrose Bio for the three and six months ended June 30, 2025 was not recorded. Our equity method investments are reviewed for indicators of impairment at each reporting period and are written down to fair value if there is evidence of a loss in value that is other-than-temporary. In June 2024, Primrose Bio entered into an equity investment from an equity firm. As a result, we recognized an impairment loss on our equity method investment in the amount of $5.8 million during the three and six months ended June 30, 2024.There was no impairment to our equity method investment during the three and six months ended June 30, 2025. Any income or loss from our equity method investments (including the impairment) is presented in other non-operating expense, net in our condensed consolidated statements of operations.
Other Investments | Other Investments Other investments represent our investments in equity securities of third parties that do not result in us having a control or significant influence over such investments. Our equity securities investments that do not have a readily determinable or estimable fair value are measured using the measurement alternative, which is cost less impairment, if any, and adjustments resulting from observable price changes in orderly transactions for the identical or similar investment of the same issuer. The amount of such impairment or adjustment recognized during the period is presented in other non-operating expense, net in our condensed consolidated statements of operations.
Share-Based Compensation | Share-Based Compensation Share-based compensation expense for awards to employees and non-employee directors is a non-cash expense and is recognized on a straight-line basis over the vesting period.
Net Income (Loss) Per Share | Net Income (Loss) Per Share Basic net income (loss) per share is calculated by dividing net income (loss) by the weighted average number of common shares outstanding during the period. Diluted net income per share is computed based on the sum of the weighted average number of common shares and potentially dilutive common shares outstanding during the period. Diluted net loss per share is computed based on the sum of the weighted average number of common shares outstanding during the period. Potentially dilutive common shares consist of shares issuable under stock options and restricted stock. Potentially dilutive common shares from stock options and restricted stock are determined using the average share price for each period under the treasury stock method. In addition, the following amounts are assumed to be used to repurchase shares: proceeds from exercise of stock options and the average amount of unrecognized compensation expense for the awards.
Foreign Currency Translation | Foreign Currency Translation The Euro is the functional currency of Apeiron and the corresponding financial statements have been translated into U.S. Dollars in accordance with ASC 830-30, Translation of Financial Statements. Assets and liabilities are translated at end-of-period rates while revenues and expenses are translated at average rates in effect during the period in which the activity took place. Equity is translated at historical rates and the resulting cumulative translation adjustments are included as a component of accumulated other comprehensive income (loss).
Accounting Standards Not Yet Adopted | Accounting Standards Not Yet Adopted In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. The update requires a public business entity to disclose, on an annual basis, a tabular rate reconciliation using both percentages and currency amounts, broken out into specified categories with certain reconciling items further broken out by nature and jurisdiction to the extent those items exceed a specified threshold. In addition, all entities are required to disclose income taxes paid, net of refunds received disaggregated by federal, state/local, and foreign and by jurisdiction if the amount is at least 5% of total income tax payments, net of refunds received. Adoption of the ASU allows for either the prospective or retrospective application of the amendment and is effective for annual periods beginning after December 15, 2024, with early adoption permitted. We will adopt this ASU prospectively for the period ending December 31, 2025, and it will impact only our disclosures, with no impacts to our financial condition or results of operations. In November 2024, the FASB issued ASU No. 2024-03, Income Statement—Reporting Comprehensive Income (Subtopic 220-40): Expense Disaggregation Disclosures. This update requires entities to disaggregate operating expenses into specific categories, such as salaries and wages, depreciation, and amortization, to provide enhanced transparency into the nature and function of expenses. ASU 2024-03 is effective for fiscal years beginning after December 15, 2026, with early adoption permitted. ASU 2024-03 may be applied retrospectively or prospectively. We are currently evaluating the new guidance to determine the impact it may have on our condensed consolidated financial statements and related disclosures. We do not believe that any other recently issued, but not yet effective accounting pronouncements, if adopted, would have a material impact on our condensed consolidated financial statements or disclosures.
