Basis of Presentation and Summary of Significant Accounting Policies
Note 1. Basis of Presentation and Summary of Significant Accounting Policies
We have prepared the accompanying unaudited condensed consolidated financial statements in accordance with the SEC requirements for interim reporting. As permitted under those rules, certain information and footnote disclosures normally included in annual financial statements prepared in accordance with generally accepted accounting principles in the U.S. (GAAP) have been condensed or omitted. The information included in this Form 10-Q should be read in conjunction with our consolidated financial statements and accompanying notes for the year ended December 31, 2024, included in our 2024 Form 10-K. The significant accounting policies set forth in Note 2 to the consolidated financial statements in our 2024 Form 10-K and the footnotes herein appropriately represent, in all material respects, the current status of our accounting policies.
In our opinion, the financial statements reflect all adjustments (including those that are normal and recurring) that are necessary for fair presentation of the results of operations for the periods shown. The preparation of financial statements in accordance with GAAP requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues, expenses and related disclosures at the date of the financial statements and during the reporting period. Actual results could differ from those estimates. In addition, results for interim periods should not be considered indicative of results for any other interim period or for the full year ending December 31, 2025, or any other future period.

Note 2. New Financial Accounting Pronouncements
In December 2023, the Financial Accounting Standards Board (FASB) issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which is intended to enhance the transparency and usefulness of income tax disclosures by providing incremental and disaggregated income tax disclosures pertaining to the effective tax rate reconciliation and income taxes paid by jurisdiction. This standard is effective for fiscal years beginning after December 15, 2024, with early adoption permitted. The standard allows for prospective or retrospective application upon adoption. We are currently assessing the impact ASU 2023-09 will have on our consolidated financial statements, including our Income Taxes footnote disclosure.
In November 2024, the FASB issued ASU 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, which is intended to provide more detailed and disaggregated information about significant expense categories, such as purchases of inventory, employee compensation, depreciation and amortization and selling expenses. This standard, including related updates, is effective for fiscal years beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027. Early adoption is permitted, and the amendments may be applied either prospectively or retrospectively. We are currently assessing the impact ASU 2024-03 will have on our consolidated financial statements, including our footnote disclosures.

Acquisitions
In 2021 and 2022, respectively, we sold manufacturing facilities in Shawnee, Kansas, and Speke, United Kingdom (U.K.) to TriRx Pharmaceuticals (TriRx), and entered into contract manufacturing supply agreements with TriRx. We received the final cash proceeds from our sale of these facilities of $66 million from TriRx, in addition to accrued interest, during the three months ended March 31, 2024.
In September 2024, TriRx Speke Ltd. (TriRx Speke), a subsidiary of TriRx, entered into trading administration, a formal insolvency process in the U.K., and we acquired the manufacturing facility in Speke, including its workforce and related assets in November 2024 for $36 million in order to minimize supply disruption for our impacted farm animal product lines. This transaction was accounted for as a business combination under the acquisition method of accounting. The following table summarizes the preliminary fair value amounts recognized for assets acquired as of the acquisition date (the accounting for this acquisition has not been finalized as of March 31, 2025):

Divestitures
New Zealand manufacturing facility: On February 27, 2025, we closed the sale of our manufacturing facility in Manukau, New Zealand, to a third party for cash proceeds of $9 million. Assets divested included property and equipment related to the facility and inventory. Additionally, approximately 50 individuals were transferred to the new owners as part of the divestiture. This transaction did not result in a material gain or loss on divestiture.
Aqua business: On July 9, 2024, we closed the sale of our aqua business to Intervet International B.V., a Dutch subsidiary of Merck Animal Health, for $1,294 million in cash, the vast majority of which was utilized to repay previously outstanding term loan debt. Our aqua business included products across both warm-water and cold-water species and generated revenues of $31 million during the three months ended March 31, 2024. Assets sold included inventories, real property and equipment, including our manufacturing sites in Canada and Vietnam, and
certain intellectual property, technology and other intangible assets, including marketed products. Additionally, approximately 280 commercial and manufacturing employees were transferred to Merck Animal Health as part of this divestiture. As of the disposal date, the carrying amounts of the following major assets were derecognized from our condensed consolidated balance sheet:
Inventories$43 
Goodwill458

Total assets $634 
Based on the aggregate carrying value of our aqua business and $20 million of costs to sell, we recorded a pre-tax gain on divestiture of $640 million in 2024. We also recognized income tax expense of approximately $170 million related to the taxable gain, a majority of which is payable in 2025.

Asset Impairment, Restructuring and Other Special Charges
Note 5. Asset Impairment, Restructuring and Other Special Charges
In recent years, we have incurred substantial costs associated with restructuring programs and cost-reduction initiatives designed to achieve a flexible and competitive cost structure. Restructuring activities have primarily included charges associated with business and facility rationalizations and workforce reductions. We have also incurred costs associated with executing acquisitions, divestitures and other significant transactions and related integration and/or separation activities. Components of asset impairment, restructuring and other special charges were as follows:

(1)Restructuring charges primarily related to cash-based severance costs associated with a restructuring program approved and announced in February 2024 intended to reallocate resources by shifting international resources from farm animal to pet health. This restructuring program also resulted in changes in how we operate in and sell into the Argentina market, among others.
(2)Acquisition and divestiture-related charges in 2024 consisted of transaction costs related to the divestiture of our aqua business (see Note 4. Acquisitions, Divestitures and Other Arrangements for further information).
(3)Other items in 2025 primarily related to upfront payments made in relation to new licensing arrangements.

During the three months ended March 31, 2025, we drew $125 million on our Revolving Credit Facility to fund working capital needs, which we subsequently repaid with the proceeds from a draw on our Securitization Facility.
(2)Our Securitization Facility is secured and collateralized by our U.S. Net Eligible Receivables Balance, bears interest at Term SOFR plus 1.25% and matures in July 2026. Our borrowing capacity under our Securitization Facility is subject to monthly fluctuation based on the level of our borrowing base as reported to the lender. During the three months ended March 31, 2025, we drew $125 million on our Securitization Facility, primarily to repay the outstanding balance on our Revolving Credit Facility (see above), with subsequent repayments totaling $40 million prior to March 31, 2025.
(3)Subsequent to issuance in August 2018, our 4.900% Senior Notes due 2028 have been subject to interest rate increases related to credit rating agency downgrades. As of March 31, 2025, these notes bear interest at a rate of 6.650%.
As of March 31, 2025, approximately 80% of our long-term indebtedness bore interest at a fixed rate, including variable-rate debt converted to fixed-rate through the use of interest rate swaps (see Note 8. Financial Instruments for additional information). We were in compliance with all of our debt covenants as of March 31, 2025.

Derivative Instruments and Hedging Activities Disclosure [Abstract]  
Financial Instruments
Note 8. Financial Instruments
To manage our exposure to market risks, such as changes in foreign currency exchange rates and variable interest rates, we have entered into various derivative transactions. Derivative cash flows are principally classified in the operating activities section of our condensed consolidated statements of cash flows, consistent with the underlying hedged item. Further, we do not offset derivative assets and liabilities on our condensed consolidated balance sheets. Our outstanding positions are discussed below.
Derivatives Not Designated as Hedges
We may enter into foreign currency exchange forward or option contracts to reduce the effects of fluctuating foreign currency exchange rates. As of March 31, 2025 and December 31, 2024, we had outstanding foreign currency exchange contracts with aggregate notional amounts of $867 million and $1,016 million, respectively. The amounts of net gains (losses) on derivative instruments not designated as hedging instruments, recorded in other expense, net for the three months ended March 31, were as follows:
20252024
Foreign exchange forward contracts (1)
$15 $(9)
(1)These amounts were substantially offset in other expense, net by the effect of changing exchange rates on the underlying foreign currency exposures.
Derivatives Designated as Hedges – Net investment hedges
At December 31, 2024, we had a series of cross-currency fixed interest rate swaps to help mitigate the impact of foreign currency fluctuations on our operations in Switzerland with a combined 1,000 million CHF notional amount with tenors in 2026 and 2027. In January 2025, we took advantage of market opportunities to restructure our net investment hedges, paying $10 million to settle these instruments early while also collecting $5 million of accrued interest. We simultaneously entered into new cross-currency fixed interest rate swaps with the same 1,000 million CHF notional amounts and covering the same tenors. These instruments were determined to be, and were designated as, effective economic hedges of net investments in our CHF denominated net assets.
The amount of (losses) gains on net investment hedges, net of tax, recorded in accumulated other comprehensive loss for the three months ended March 31, were as follows:
20252024
Cross-currency fixed interest rate swaps$(24)$62 
During the three months ended March 31, 2025 and 2024, these instruments also generated $11 million and $8 million of interest income, respectively, which was included as a contra interest expense, net of capitalized interest in our condensed consolidated statements of operations.
Derivatives Designated as Hedges – Interest rate swaps
We had outstanding interest rate swaps with aggregate notional amounts of $2,800 million as of both March 31, 2025 and December 31, 2024, which have scheduled maturities in 2026. As of March 31, 2025 and December 31, 2024, we also had forward-starting interest rate swap agreements with a combined notional amount of $850 million, which will become effective on August 1, 2026, and mature in line with the applicable Incremental Term Facility maturities, which range between 2028 and 2031.
The amounts of (losses) gains on interest rate swap contracts, net of tax, recorded in accumulated other comprehensive loss for the three months ended March 31, were as follows:
20252024
Interest rate swaps$(16)$63 
The amounts of gains reclassified out of accumulated other comprehensive loss and recognized into earnings through interest expense, net of capitalized interest for the three months ended March 31, were as follows:
20252024
Interest rate swaps$13 $31 
Over the next 12 months, we expect to reclassify a gain of $9 million out of accumulated other comprehensive loss and into interest expense, net of capitalized interest related to our interest rate swaps.
As of March 31, 2025, when factoring in the impact from our interest rate swaps, the weighted-average effective interest rate on our outstanding indebtedness was 6.21% (excluding the expected future reclassifications to interest expense, net of capitalized interest related to past interest rate swap settlements).

Fair Value Disclosures [Abstract]  
Fair Value
Note 9. Fair Value
Fair value is defined as the exchange price that would be received to sell an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Fair value measurements are based on a framework that utilizes the inputs market participants use to determine the fair value of an asset or liability and establishes a fair value hierarchy to prioritize those inputs. Level 1 fair value measurements are based on quoted prices in active markets for identical assets or liabilities. We determine our Level 2 fair value measurements based on a market approach using quoted market values or significant other observable inputs for identical or comparable assets or liabilities. Our Level 3 fair value measurements are based on unobservable inputs based on little or no market activity.
The following table summarizes the fair value information at March 31, 2025 and December 31, 2024, for assets and liabilities measured at fair value on a recurring basis in the respective balance sheet line items, as well as long-term debt, for which fair value is disclosed on a recurring basis:

Cash and cash equivalents include cash on hand and all highly liquid investments with original maturities at the time of purchase of three months or less. The carrying values of cash and cash equivalents, accounts and other receivables, accounts payable and other current liabilities are reasonable estimates of their fair values due to the short-term nature of these assets and liabilities.
Contingent consideration liabilities presented in both periods relate to our past acquisitions of NutriQuest, LLC and NutriQuest Nutricao Animal Ltda. Contingent consideration for these acquisitions remains payable to the extent certain specific development, sales and geographic milestones are achieved, as outlined in the asset purchase agreements. The fair values of these liabilities were estimated using a Monte Carlo simulation model, consisting of inputs not observable in the market, including estimates relating to revenue forecasts, discount rates and volatility. We also had investments without readily determinable fair values which were classified as other noncurrent assets on our condensed consolidated balance sheets totaling $15 million and $17 million as of March 31, 2025 and December 31, 2024, respectively. These investments are not recorded at fair value on a recurring basis, and as such, are not included in the fair value table above.

Income tax benefit$(7)$(20)
Effective tax rate(12.2)%(182.2)%
For the three months ended March 31, 2025 and 2024, we recognized income tax benefits of $7 million and $20 million, respectively. Our effective tax rate for the three months ended March 31, 2025, of (12.2)% differed from the statutory income tax rate primarily due to the tax impact from the jurisdictional mix of projected income and losses in non-U.S. jurisdictions and the utilization of net operating losses and a valuation allowance release in the U.S. Our effective tax rate of (182.2)% for the three months ended March 31, 2024, differed from the statutory
income tax rate primarily due to the partial release of a valuation allowance attributable to the anticipated sale of our aqua business, which closed on July 9, 2024, and a benefit related to the recognition of certain state tax credits.
We were included in Eli Lilly and Company's (Lilly's) U.S. tax examinations by the Internal Revenue Service through the full separation date of March 11, 2019. Pursuant to the tax matters agreement we executed with Lilly in connection with our initial public offering (IPO), the potential liabilities or potential refunds attributable to pre-IPO periods in which Elanco was included in a Lilly consolidated or combined tax return remain with Lilly. The U.S. examination of tax years 2016 to 2018 began in 2019 and remains ongoing. Final resolution of certain matters is dependent upon several factors, including the potential for formal administrative proceedings.

Legal Matters
We are party to various legal actions that oftentimes arise in the normal course of business. The most significant matters are described below. Under GAAP, loss contingency provisions are recorded when we deem it probable that we will incur a loss and we are able to formulate a reasonable estimate of that loss. For the legal matters discussed below, we either believe loss is not probable or are unable to reasonably estimate the possible loss or range of loss, if any. The process of resolving these matters is inherently uncertain and may develop over an extended period of time; therefore, at this time, the ultimate resolutions cannot be predicted. As of March 31, 2025 and December 31, 2024, we had no material liabilities established related to the legal matters discussed below.
On October 7, 2024, a putative securities class action lawsuit captioned Joseph Barpar v. Elanco Animal Health Inc., et al. (Barpar) was filed in the U.S. District Court for the District of Maryland against Elanco and two of its executives. Barpar alleged claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 (the Act), and specifically alleged that Elanco and the two executives made materially false and/or misleading statements and/or failed to disclose certain facts about the safety of and labeling for our Zenrelia® product, as well as the approval and launch timelines for Zenrelia and our Credelio Quattro™ product. The plaintiff purported to represent purchasers of Elanco securities between November 7, 2023 and June 26, 2024. On March 21, 2025, plaintiff filed an amended complaint that extended the time period for which the plaintiff purported to represent purchasers of Elanco securities to between May 9, 2023 and June 26, 2024. The amended complaint also removed allegations concerning the approval and launch timelines for our Credelio Quattro product. On November 1, 2024, a shareholder derivative action captioned Lawrence Hollin v. Lawrence E. Kurzius, et al. (Hollin) was filed in the U.S. District Court for the District of Maryland against current members of Elanco's Board of Directors and senior management, alleging claims under Sections 10(b) and 20(a) of the Act and state law claims for breach of fiduciary duty, aiding and abetting breach of fiduciary duty, unjust enrichment and waste of corporate assets, based on allegations substantially similar to the allegations in the putative class action complaint in Barpar. On March 11, 2025, a shareholder derivative action captioned James Habermehl v. Jeffrey N. Simmons, et al. was filed in Hancock County Circuit Court of Indiana, against the same parties named in Hollin, alleging claims under Indiana state law for breach of fiduciary duty and unjust enrichment, based on allegations substantially similar to the allegations in the putative class action complaint in Barpar. On April 28, 2025, a shareholder derivative action captioned Christopher Dougherty v. Elanco Animal Health, Inc., et al. (Dougherty), was filed in the District of Maryland, naming certain Elanco executives and 13 Elanco Board members as defendants. Dougherty alleges the defendants engaged in conspiratorial and individually culpable conduct based on materially false or misleading statements and omissions alleged in, referenced or related to, in large part, the putative class action complaint in Barpar, as well as breach of fiduciary duty, unjust enrichment, abuse of control, gross mismanagement, waste of corporate assets, and as to the certain executives, contribution under Section 15, U.S.C. § 78j(b) and Section 21D of the Act. We are vigorously defending our positions in connection with each of these actions.
On May 20, 2020, a shareholder class action lawsuit captioned Hunter v. Elanco Animal Health Inc., et al. (Hunter) was filed in the U.S. District Court for the Southern District of Indiana against Elanco and certain executives. On September 3, 2020, the court appointed a lead plaintiff, and on November 9, 2020, the lead plaintiff filed an amended complaint adding additional claims against Elanco, certain executives and other individuals. The lawsuit alleged, in part, that Elanco and certain of its executives made materially false and/or misleading statements and/or failed to disclose certain facts about Elanco’s supply chain, inventory, revenue and projections. The lawsuit sought unspecified monetary damages and purports to represent purchasers of Elanco securities between September 30, 2018 and May 6, 2020, and purchasers of Elanco common stock issued in connection with Elanco's acquisition of Aratana Therapeutics, Inc. On January 13, 2021, we filed a motion to dismiss, and on August 17, 2022, the Court issued an order granting our motion to dismiss the case without prejudice. On October 14, 2022, the plaintiffs filed a motion for leave to amend the complaint. On December 7, 2022, we filed an opposition to the plaintiffs' motion, and on September 27, 2023, the court denied the plaintiffs' motion for leave, issuing final judgment in favor of Elanco. On October 25, 2023, the plaintiffs filed a notice of appeal to the U.S. Court of Appeals for the Seventh Circuit. We intend to continue to vigorously defend our position.
On October 16, 2020, a shareholder class action lawsuit captioned Safron Capital Corporation v. Elanco Animal Health Inc., et al. was filed in the Marion Superior Court of Indiana against Elanco, certain executives and other individuals and entities. On December 23, 2020, the plaintiffs filed an amended complaint adding an additional plaintiff. The lawsuit alleges, in part, that Elanco and certain of its executives made materially false and/or misleading statements and/or failed to disclose certain facts about Elanco’s relationships with third-party distributors and revenue attributable to those distributors within the registration statement on Form S-3 dated January 21, 2020, and accompanying prospectus filed in connection with Elanco’s public offering which closed on or about January 27, 2020. The lawsuit seeks unspecified monetary damages and purports to represent purchasers of Elanco common stock or tangible equity units issued in connection with the public offering. From February 2021 to August 2022, this case was stayed in deference to Hunter. On October 24, 2022, we filed a motion to dismiss. On December 23, 2022, the plaintiffs filed their opposition to the motion to dismiss. Prior to the ruling on the motion to dismiss, on June 8, 2023, the plaintiffs filed a motion for leave to file a second amended complaint, which is now the operative complaint. We filed a motion to dismiss the second amended complaint on August 7, 2023, to which the plaintiffs filed their opposition on October 13, 2023. On April 17, 2024, our motion to dismiss was granted. On or about October 4, 2024, the plaintiffs appealed the dismissal to the Indiana Court of Appeals. Subsequently, on or about March 20, 2025, the plaintiffs' motion for oral argument was denied. We intend to continue to vigorously defend our position.
In the third quarter of 2019, Tevra Brands, LLC (Tevra) filed a complaint in the U.S. District Court of the Northern District of California, alleging that Bayer Animal Health (acquired by us in August 2020) had been involved in unlawful, exclusive dealing and tying of its flea and tick products Advantage, Advantix and Seresto™ and maintained a monopoly in the market. The complaint was amended in March 2020 and then dismissed in September 2020 with leave to amend. A second amended complaint was filed in March 2021 and realleged claims of unlawful exclusive dealing related to Advantage and Advantix and monopoly maintenance. A motion to dismiss the second amended complaint was denied in January 2022. Tevra’s demands included both actual and treble damages. On April 16, 2024, the court granted our motion for summary judgment to exclude all damages subsequent to our acquisition of Bayer Animal Health in August 2020. A jury trial was held in July 2024, and on August 1, 2024, the jury returned a verdict in favor of Bayer Animal Health. In January 2025, Tevra's motion for a new trial was denied, and in February 2025, Tevra filed its notice of appeal. Following the initial Tevra trial, three additional matters have been filed against us, both in the Northern District of California and in the Southern District of Indiana, most recently in January 2025: Tracy Spradlin v. Elanco Animal Health, Inc. (Spradlin), Tevra Brands, LLC v. Elanco Animal Health, Inc. (Tevra v. Elanco), and Susan Kraus-Silfen v. Elanco Animal Health, Inc. et. al. (Kraus-Silfen). While there are substantive and statutory differences, the allegations underpinning these matters are similar in some respects to the initial Tevra matter including, but not limited to, the family of pet health products and sales tactics and agreements alleged to drive a monopoly within the market. Spradlin and Kraus-Silfen are putative class actions, and all three of these additional matters seek injunctive relief and an unspecified amount of monetary relief. On March 31, 2025, our motion to dismiss Tevra v. Elanco was granted by the court without prejudice to plaintiff's right to file an amended claim. We are vigorously defending against the claims made in these matters.
Other Commitments
As of March 31, 2025, we had a lease commitment that has not yet commenced for our new corporate headquarters in Indianapolis, Indiana. Total minimum lease payments are estimated to be approximately $378 million over a term of 25 years, excluding extensions. Final lease payments may vary depending on the actual cost of certain construction activities. Lease commencement is expected in 2025.
The land for our new corporate headquarters is located in a Tax Increment Finance District, and the project is, in part, funded through Tax Incremental Financing (TIF) through an incentive agreement between the City of Indianapolis and us. The agreement provides for an estimated total incentive of $64 million to be funded by the City of Indianapolis in connection with the future tax increment revenue generated from the developed property. In December 2021, as part of a funding and development agreement entered into between the developer and us, we made a commitment to use the expected TIF proceeds towards the cost of developing and constructing the headquarters. In exchange, the developer reimbursed us up to the $64 million commitment in 2021. During 2022, we refunded approximately $15 million of the TIF proceeds to the developer. As a result, it is our expectation that our future lease payments will be reduced. The remaining accrued incentive was principally included in other noncurrent liabilities on our condensed consolidated balance sheets and will be amortized over the period we expect to benefit from the use of the new headquarters.

Earnings Per Share [Abstract]  
Earnings Per Share
Note 12. Earnings Per Share
We compute basic earnings per share by dividing net income by the weighted-average number of common shares outstanding for the reporting period. Elanco has variable common stock equivalents relating to certain equity awards in stock-based compensation arrangements. Diluted earnings per share reflects the potential dilution that could have occurred if holders of the unvested equity awards converted their holdings into common stock. The weighted-average number of potentially dilutive shares outstanding was calculated using the treasury stock method. Potential
common shares that would have had the effect of increasing diluted earnings per share were considered to be anti-dilutive and as such, these shares were not included in the calculation of diluted earnings per share.
Basic and diluted weighted-average shares outstanding were as follows:

(1)For the three months ended March 31, 2025 and 2024, approximately 3.7 million and 0.8 million, respectively, of potential common shares were excluded from the calculation of diluted weighted-average shares outstanding because their effect was anti-dilutive.

Segment Reporting [Abstract]  
Business Segment Information
Note 13. Business Segment Information
We operate our business as a single segment engaged in the development, manufacturing, marketing and sales of animal health products for both pets and farm animals. Consistent with our operational structure, our Chief Executive Officer (CEO), as the chief operating decision maker, makes resource allocation and business process decisions globally across our consolidated business. Strategic and resource allocation decisions are managed globally, with global functional leaders responsible for determining significant costs and investments and with regional leaders responsible for overseeing the execution of our global strategy. Managing and allocating resources at the global corporate level enables our CEO to assess the overall level of resources available and how to best deploy these resources across functions, product types, regional commercial organizations and R&D projects in line with our overarching long-term corporate-wide strategic goals, rather than on a product or geographic basis. Consistent with this decision-making process, our CEO considers consolidated net income (loss), which is our single segment’s principal measure of segment profit and loss, when evaluating performance. Our CEO also considers these measures, as well as other factors, such as an assessment of a new product’s future market potential, when determining how to allocate company-wide resources.
Significant expenses are amounts that are regularly provided to our CEO and included in consolidated net income (loss), our primary measure of our single segment’s profit or loss. Our CEO regularly reviews reported consolidated revenues, gross profit, and other significant expenses and consolidated net income (loss), in addition to forecasted revenues, significant expenses and net income (loss) amounts for future periods. A summary of our consolidated net income for the three months ended March 31, 2025 and 2024 is as follows, including the significant expenses provided to and regularly reviewed by our CEO, as well as other expenses, which are included in consolidated net income, but are not regularly provided to and/or reviewed by our CEO:

Sale of Future Royalties and Milestones
In May 2025, we executed a Purchase and Sale Agreement (PSA) with funds affiliated with Blackstone Life Sciences and Blackstone Credit & Insurance (collectively, Blackstone). Pursuant to the PSA, we received a payment of $295 million from Blackstone for the rights to the proceeds from (a) the future royalties we are owed from net sales in the U.S. of XDEMVY® (lotilaner ophthalmic solution) 0.25%, a medical treatment for Demodex blepharitis in humans, by Tarsus Pharmaceuticals, Inc. (Tarsus) and (b) certain sales milestones we are owed based on global net sales of XDEMVY, both of which are pursuant to the terms of a previously executed license agreement with Tarsus. The PSA applies to net sales of XDEMVY in the U.S. from April 1, 2025 through August 24, 2033. We retain the rights to all royalty payments on net sales outside the U.S., and ownership of any royalties due on U.S. net sales after August 24, 2033, will remain with us. We also retain the rights to any future royalties or milestones earned due to the future expansion of lotilaner in other human health applications.
Under GAAP, the $295 million proceeds, net of estimated costs of $5 million, will be recorded as a liability for the sale of future revenue on our consolidated balance sheets. The transaction costs will be amortized to interest expense over the life of the arrangement. Under the terms of the PSA, we will be liable to pay Blackstone any qualifying royalties and milestones received from Tarsus. We will continue to recognize the future U.S. royalty revenues and milestone payments in our consolidated statements of operations, while incurring imputed interest expense associated with this liability. As royalty payments are earned by us and remitted to Blackstone, the balance of the liability will be reduced to the extent the payments remitted to Blackstone exceed the imputed interest expense for the period.

New Financial Accounting Pronouncements
In December 2023, the Financial Accounting Standards Board (FASB) issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which is intended to enhance the transparency and usefulness of income tax disclosures by providing incremental and disaggregated income tax disclosures pertaining to the effective tax rate reconciliation and income taxes paid by jurisdiction. This standard is effective for fiscal years beginning after December 15, 2024, with early adoption permitted. The standard allows for prospective or retrospective application upon adoption. We are currently assessing the impact ASU 2023-09 will have on our consolidated financial statements, including our Income Taxes footnote disclosure.
In November 2024, the FASB issued ASU 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, which is intended to provide more detailed and disaggregated information about significant expense categories, such as purchases of inventory, employee compensation, depreciation and amortization and selling expenses. This standard, including related updates, is effective for fiscal years beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027. Early adoption is permitted, and the amendments may be applied either prospectively or retrospectively. We are currently assessing the impact ASU 2024-03 will have on our consolidated financial statements, including our footnote disclosures.
