FORWARD-LOOKING STATEMENTS AND RISK FACTOR SUMMARY
This Quarterly Report on Form 10-Q (Form 10-Q) includes forward-looking statements within the meaning of the federal securities laws. These forward-looking statements include, without limitation, statements concerning the impact on Elanco Animal Health Incorporated and its subsidiaries (collectively, Elanco, the Company, we, us or our) caused by the integration of business acquisitions, expected synergies and cost savings, product launches, global macroeconomic conditions, expectations relating to liquidity and sources of capital, our expected compliance with debt covenants, cost savings, expenses and reserves relating to restructuring actions, our industry and our operations, performance and financial condition, and including, in particular, statements relating to our business, growth strategies, distribution strategies, product development efforts and future expenses.
Forward-looking statements are based on our current expectations and assumptions regarding our business, the economy and other future conditions. Because forward-looking statements relate to the future, by their nature, they are subject to inherent uncertainties, risks and changes in circumstances that are difficult to predict. As a result, our actual results may differ materially from those contemplated by the forward-looking statements. Important risk factors that could cause actual results to differ materially from those in the forward-looking statements include regional, national or global political, economic, business, competitive, market and regulatory conditions, including but not limited to the following:
•operating in a highly competitive industry;
•the success of our research and development (R&D) and licensing efforts;

See Item 1A, “Risk Factors,” of Part I of our Annual Report on Form 10-K for the year ended December 31, 2023, filed with the United States (U.S.) Securities and Exchange Commission (SEC) (2023 Form 10-K), and Part II of this Form 10-Q, for a further description of these and other factors. Although we have attempted to identify important risk factors, there may be other risk factors not presently known to us or that we presently believe are not material that could cause actual results and developments to differ materially from those made in or suggested by the forward-looking statements contained in this quarterly report. If any of these risks materialize, or if any of the above assumptions underlying forward-looking statements prove incorrect, actual results and developments may differ materially from those made in or suggested by the forward-looking statements contained in this quarterly report. We caution you against relying on any forward-looking statements, which should also be read in conjunction with the other cautionary statements that are included elsewhere in this quarterly report. Any forward-looking statement made by us in this quarterly report speaks only as of the date hereof. Factors or events that could cause our actual results to differ may emerge from time to time, and it is not possible for us to predict all of them. We undertake no obligation to publicly update or to revise any forward-looking statement, whether as a result of new information, future developments or otherwise, except as may be required by law.

Elanco Animal Health Incorporated
Notes to Condensed Consolidated Financial Statements (Unaudited)
(Tables present dollars and shares in millions, except per-share and per-unit data)

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, 2023, included in our 2023 Form 10-K. 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, 2024, or any other future period.
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. In preparing financial statements in conformity with GAAP, we must make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, expenses and related disclosures at the date of the financial statements and during the reporting period. Actual results could differ from those estimates. Certain reclassifications of prior year information have been made to conform to the current year's presentation.
The significant accounting policies set forth in Note 2 to the consolidated financial statements in our 2023 Form 10-K and the footnotes herein appropriately represent, in all material respects, the current status of our accounting policies.

Note 2. New Financial Accounting Pronouncements
The following table provides a brief description of accounting standards applicable to us that we have not yet adopted:
StandardDescriptionEffective DateEffect on the Financial Statements or Other Significant Matters
ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures
ASU 2023-07 is intended to improve disclosure requirements related to reportable segments, primarily through enhanced disclosures about significant segment expenses that are regularly provided to the chief operating decision maker (CODM) for purposes of assessing a segment's profit or loss and deciding how to allocate resources. This new standard applies to all public entities, including entities, like us, with a single reportable segment.This new standard is effective for fiscal years beginning after December 31, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. Adoption requires retrospective application.We are currently assessing the impact ASU 2023-07 will have on our consolidated financial statements, including our footnote disclosures.
ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures
ASU 2023-09 is intended to enhance the transparency and decision usefulness of income tax disclosures by enhancing information about how an entity's operations and related tax risks and its tax planning and operational opportunities affect its tax rate and prospects for future cash flows.The guidance is effective for fiscal years beginning after December 31, 2024, with early adoption permitted. Adoption allows for prospective application, with retrospective application permitted.We are currently assessing the impact ASU 2023-09 will have on our consolidated financial statements, including our Income Taxes footnote disclosure.

Note 3. Revenue
We recognize revenue primarily from product sales to customers. Revenue from sales of products is recognized at the point where the customer obtains control of the goods and we satisfy our performance obligations, which is generally once the goods have been shipped and the customer has assumed title. For contract manufacturing organization (CMO) arrangements, we recognize revenue over time or at a point in time depending on our evaluation of when the customer obtains control of the promised goods or services.
2024 Q2 Form 10-Q | 9
Provisions for sales rebates and discounts are recorded as a reduction to revenue in the period the related sales are recognized and are based on specific agreements. In determining the appropriate accrual amount, we consider our historical experience with similar incentive programs, current sales data and estimates of inventory levels at our channel distributors. The following table summarizes the activity in our global sales rebates and discounts liability:

Adjustments to revenue recognized due to changes in estimates for products shipped in previous periods were not material for either the six months ended June 30, 2024 or 2023. Actual global product returns were approximately 1% of net revenue for the six months ended June 30, 2024 and 2023.

We have a single customer that accounted for approximately 10% and 9% of revenue for the six months ended June 30, 2024 and 2023, respectively. Product sales with this customer resulted in accounts receivable of $112 million and $78 million at June 30, 2024 and December 31, 2023, respectively.

Note 4. Acquisitions, Divestitures and Other Arrangements
Acquisitions
During 2023, we completed the acquisitions of certain U.S. marketed products, pipeline products, inventory and an assembled workforce from NutriQuest, LLC (NutriQuest) and certain assets including inventory and distribution rights for certain marketed products from NutriQuest Nutricao Animal Ltda (NutriQuest Brazil). Each of these transactions was accounted for as a business combination under the acquisition method of accounting. The acquisition method requires, among other things, that assets acquired and liabilities assumed be recognized at their fair values as of the acquisition date. The determination of estimated fair value requires management to make significant estimates and assumptions. The excess of the purchase price over the fair value of the acquired net assets, where applicable, has been recorded as goodwill.
NutriQuest
On January 3, 2023, we acquired NutriQuest for total purchase consideration of $59 million. NutriQuest is a provider of swine, poultry and cattle nutritional health products to animal producers. The acquisition helped us expand our
2024 Q2 Form 10-Q | 10
existing nutritional health offerings and further our efforts to explore innovative antibiotic alternatives. The composition of the purchase price was as follows:
Up-front cash consideration$16 
Deferred cash consideration paid January 4, 20245 
Fair value of contingent consideration38 
Total purchase consideration$59 
Contingent consideration for this acquisition includes up to $85 million of cash consideration payable if specific development, sales and geographic expansion milestones are achieved, as outlined in the asset purchase agreement. The initial fair value of this contingent consideration liability of $38 million was estimated at the acquisition date using a Monte Carlo simulation model, which represented a Level 3 measurement under the fair value hierarchy (see Note 10. Fair Value for further information).
The following table summarizes the fair values of assets acquired as of the acquisition date:
Inventories$3 
Intangible assets:
Marketed products29 
Acquired in-process research and development (IPR&D)9 
Other intangible assets15 
Total identifiable assets56 
Goodwill3 
Total consideration transferred$59 
Other intangible assets consist of customer relationships and trade names. The acquired definite-lived intangible assets are being amortized over a weighted-average estimated useful life of approximately 12 years on a straight-line basis.
NutriQuest Brazil
On August 1, 2023, we acquired NutriQuest Brazil for total purchase consideration of $19 million. The composition of the purchase price included cash paid on the closing date of $3 million, with additional consideration payable through 2026 valued at approximately $16 million, a portion of which is contingent upon the continuation of certain terms and conditions set forth in the asset purchase agreement.
The following table summarizes the fair values of assets acquired as of the acquisition date:
Inventories$3 
Definite-lived intangible assets15 
Total identifiable assets18 
Goodwill1 
Total consideration transferred$19 
The acquired definite-lived intangible assets are being amortized over a weighted-average estimated useful life of approximately nine years on a straight-line basis.
Divestitures
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 approximately $1.3 billion in cash. Following the close, we used proceeds from this sale to repay $1,222 million of term loan debt (see Note 8. Debt for further information). Our aqua business included products across both warm-water and cold-water species and generated revenues of $80 million and $90 million during the six months ended June 30, 2024 and 2023, respectively. Given that we operate our business as a single reporting unit, we are unable to reasonably determine stand-alone costs and related earnings or loss before income taxes attributable to our aqua business. 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. Along with these assets, approximately 280 commercial and manufacturing employees were transferred to Merck Animal Health as part of this divestiture.
We determined the aqua business assets sold (the disposal group) met all the required criteria to be classified as held for sale in February 2024. Accordingly, at that time we ceased depreciation and amortization of the long-lived assets included within the disposal group. Given the closing of the transaction on July 9, 2024, these assets remained classified as held for sale on our condensed consolidated balance sheet as of June 30, 2024. We also
2024 Q2 Form 10-Q | 11
determined that the sale of our aqua business did not qualify for reporting as a discontinued operation, as it did not represent a strategic shift that will have a major effect on our operations and/or financial results.
While the accounting for the aqua sale is not yet complete, we expect to record a pre-tax gain on divestiture of approximately $630 million to $660 million during the third quarter of 2024. In establishing the carrying value of our disposal group, a portion of our single reporting unit’s goodwill was allocated to the disposal group on a relative fair value basis. In determining the relative fair value of the disposal group to our single reporting unit as a whole, we compared the fair value of the disposal group to an estimated fair value of our single reporting unit, which was based on a fair value assessment using the income approach. The income approach is a valuation technique that provides an estimate of fair value based on market participant expectations of the cash flows an asset would generate over its remaining useful life. Significant management judgment was required in estimating the fair value of our single reporting unit, including, but not limited to, estimates and assumptions regarding future cash flows of our single reporting unit, revenue growth and other profitability measures, such as gross margin and earnings before interest, taxes, depreciation and amortization (EBITDA) margin, and the determination of an appropriate discount rate. We consider this valuation approach to be a Level 3 measurement under the fair value hierarchy.
As of June 30, 2024, the carrying amounts of the following major assets were classified as held for sale on our condensed consolidated balance sheet:
Inventories$43 
Goodwill458 
Other intangibles, net50 
Property and equipment, net68 
Other assets8 
Total assets held for sale$627 
Shawnee and Speke
In August 2021 and February 2022, we completed the sales of our Shawnee, Kansas and Speke, U.K. sites, respectively to TriRx Pharmaceuticals (TriRx). Based on the original terms of the sales agreements, we anticipated receiving cash consideration from TriRx over a three-year period, and we received cash proceeds of $13 million from TriRx in 2022. In May 2023, we entered into amendments to the agreements (the amended agreement), which effectively restructured the payment schedule related to the remaining amount owed. At December 31, 2023, our remaining net receivable balance from TriRx under the amended agreement was $69 million. In February 2024, we received $66 million, in addition to accrued interest. The final $3 million was due from TriRx on August 1, 2024. While this amount has not yet been paid, based on our current assessment, we continue to believe this amount is collectible.

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 product, facility and business rationalizations and workforce reductions. We have also incurred costs associated with executing acquisition, divestiture 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 in 2024 primarily related to expected 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 directly related to the recent divestiture of our aqua business (see Note 4. Acquisitions, Divestitures and Other Arrangements for further information). Acquisition and divestiture-related charges
2024 Q2 Form 10-Q | 12
in 2023 primarily represented costs associated with the implementation of new systems, programs and processes due to the integration of Bayer Animal Health.
(3)Asset impairments principally reflected the write-off of our IL-4R IPR&D asset ($53 million), which was acquired from Kindred Biosciences, Inc. in 2021. In June 2024, we completed required studies for IL-4R, and while no adverse events were reported, the performance of the product did not meet efficacy expectations to attain commercial viability. As such, future research and development activities were terminated and the IPR&D asset was written-off.

Balance at December 31, 2023$7 
Charges43 
Cash paid(20)
Balance at June 30, 2024$30 
Timing of when the restructuring reserve obligations are expected to be paid can vary due to certain country-specific negotiations and regulations. Of the total reserve, $21 million is included within other current liabilities on our condensed consolidated balance sheet at June 30, 2024, with the remainder included within other noncurrent liabilities.

Note 6. Inventories
Inventories are stated at the lower of cost and net realizable value. We value a majority of our inventories using the first-in, first-out (FIFO) method, although we use the last-in, first-out (LIFO) method for a portion of our inventories.
Inventories consisted of the following:

Note 7. Equity
Tangible Equity Unit (TEU) Offering
In January 2020 we issued 11 million in TEUs at the stated amount of $50 per unit. The TEU prepaid stock purchase contracts were converted into shares of our common stock on February 1, 2023. Holders of our TEUs received 1.5625 shares of our common stock based on the maximum settlement rate for the applicable market value being below $32.00. In total, we issued approximately 17 million shares to holders in connection with the settlement.

(1)Our Revolving Credit Facility provides up to $750 million in borrowing capacity (with incremental capacity if certain conditions are met) and bears interest at Term SOFR plus 2.10%. On July 3, 2024, we amended our Revolving Credit Facility, which extended its maturity through July 2029.
2024 Q2 Form 10-Q | 13
(2)Our Securitization Facility is secured and collateralized by our U.S. Net Eligible Receivables Balance, has a maximum borrowing capacity of $300 million, bears interest at Term SOFR plus 1.25% and matures in July 2026.
(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 June 30, 2024, these notes bear interest at a rate of 6.650%.
(4)Upon receiving the cash proceeds associated with the sale of our aqua business (see Note 4. Acquisitions, Divestitures and Other Arrangements for further information), we repaid $1,222 million of term loan debt that was outstanding as of June 30, 2024. The following table summarizes the amounts paid and subsequent balances by term loan facility:
June 30, 2024Subsequent Pay DownAugust 8, 2024
Incremental Term Facility due 2025$175 $(40)$135 
Incremental Term Facility due 2028486 (114)372 
Incremental Term Facility due 2029246 (57)189 
Term Loan B due 20273,817 (1,011)2,806 
Subsequent to the above noted debt pay down and the related $1,000 million interest rate swap settlement (see Note 9. Financial Instruments for additional information), approximately 79% of our long-term indebtedness bears interest at a fixed rate, including variable-rate debt converted to fixed-rate through the use of interest rate swaps. We were in compliance with all of our debt covenants as of June 30, 2024.

Note 9. Financial Instruments
To manage our exposure to market risks, such as changes in foreign currency exchange rates and interest rates, we have entered into various derivative transactions. We formally assess, designate and document, as a hedge of an underlying exposure, each qualifying derivative instrument that will be accounted for as an accounting hedge at inception. We also assess at least quarterly thereafter whether the financial instruments used in the hedging transaction are effective at offsetting changes in either the fair values or cash flows of the underlying exposures. Derivative cash flows are principally classified in the operating activities section of the condensed consolidated statements of cash flows, consistent with the underlying hedged item. Further, we do not offset derivative assets and liabilities on the condensed consolidated balance sheets.
Derivatives not designated as hedges
We may enter into foreign exchange forward or option contracts to reduce the effect of fluctuating foreign currency exchange rates. Foreign currency derivatives used for hedging are put in place using the same or like currencies and duration as the underlying exposures and are recorded at fair value with the gain or loss recognized in other expense, net in the condensed consolidated statements of operations. Forward contracts generally have maturities not exceeding 12 months. As of June 30, 2024 and December 31, 2023, we had outstanding foreign exchange contracts with aggregate notional amounts of $1,015 million and $891 million, respectively.
The amounts of net gains (losses) on derivative instruments not designated as hedging instruments, recorded in other expense, net were as follows:
Three Months Ended June 30,Six Months Ended June 30,
2024202320242023
Foreign exchange forward contracts (1)
$3 $(1)$(6)$1 
(1)These amounts were substantially offset in other expense, net by the effect of changing exchange rates on the underlying foreign currency exposures.
Derivatives designated as hedges - Net investment hedges
In September 2023 we entered into a series of cross-currency fixed interest rate swaps to help mitigate the impact of foreign currency fluctuations on our operations in Switzerland with a combined 1,000 million CHF notional amount with tenors in 2026 and 2027. These instruments were determined to be, and were designated as, effective economic hedges of net investments in our CHF denominated net assets. The fair values of these instruments were estimated based on quoted market values of similar hedges and are classified as Level 2 in the fair value hierarchy (see Note 10. Fair Value for further information). Gains or losses related to these instruments due to spot rate fluctuations are recorded as cumulative translation adjustments as a component of other comprehensive income (loss). Gains and losses will remain in accumulated other comprehensive income (loss) until either the sale or substantial liquidation of the hedged subsidiary. (Losses) gains on net investment hedges, net of tax, recorded in other comprehensive (loss) income, were as follows:
Three Months Ended June 30,Six Months Ended June 30,
2024202320242023
Cross-currency fixed interest rate swaps$(10)$— $52 $— 
2024 Q2 Form 10-Q | 14
During the six months ended June 30, 2024, these instruments also generated $15 million of interest income, 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
To manage our exposure to variable interest rate risk, we utilize interest rate swap contracts to effectively convert our variable-rate debt into fixed-rate debt. We recognize any differences between the variable interest rate payments and the fixed interest rate settlements with the swap counterparties as an adjustment to interest expense, net of capitalized interest over the life of the swaps. We have designated our interest rate swaps as cash flow hedges and record them at fair value on the condensed consolidated balance sheets. Changes in the fair value of the hedges are recognized in other comprehensive income (loss) and reclassified into earnings through interest expense, net of capitalized interest at the time earnings are affected by the hedged transaction. Fair value is estimated based on quoted market values of similar hedges and is classified as Level 2 in the fair value hierarchy.
We had outstanding interest rate swaps, with aggregate notional amounts of $3,800 million as of both June 30, 2024 and December 31, 2023. As of June 30, 2024, our interest rate swap instruments had maturities ranging between 2026 and 2028. The amounts of gains on our interest rate swap contracts, net of tax, recorded in other comprehensive (loss) income were as follows:
Three Months Ended June 30,Six Months Ended June 30,
2024202320242023
Interest rate swaps$21 $59 $84 $41 
The amounts of gains reclassified from accumulated other comprehensive loss and recognized into earnings through interest expense, net of capitalized interest were as follows:
Three Months Ended June 30,Six Months Ended June 30,
2024202320242023
Interest rate swaps$30 $30 $61 $60 
Following the sale of our aqua business and the associated debt pay down (see Note 4. Acquisitions, Divestitures and Other Arrangements and Note 8. Debt for further information), we also settled $1,000 million of existing interest rate swaps, which reduced the aggregate notional amount of our interest rate swaps to $2,800 million. We received cash proceeds of approximately $5 million upon these settlements, which will be recorded in accumulated other comprehensive loss during the third quarter of 2024 and amortized to interest expense, net of capitalized interest over the original term of the interest rate swaps. Subsequent to these settlements, all remaining interest rate swaps have scheduled maturities in 2026. Over the next 12 months, we expect to reclassify a gain of $84 million from accumulated other comprehensive loss into interest expense, net of capitalized interest related to our current and previously settled interest rate swaps.
When factoring in the above noted $1,222 million debt pay down and the related $1,000 million swap settlement, the weighted-average effective interest rate on our outstanding indebtedness was 6.47% (excluding the expected future reclassifications to interest expense, net of capitalized interest related to past interest rate swap settlements).

Note 10. 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 June 30, 2024 and December 31, 2023, 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 a reasonable estimate of their fair values due to the short-term nature of these assets and liabilities. We also had investments without readily determinable fair values and equity method investments, which were classified as other noncurrent assets on our condensed consolidated balance sheets totaling $24 million and $26 million as of June 30, 2024 and December 31, 2023, 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.
The fair values of contingent consideration liabilities related to our acquisition of NutriQuest were estimated using the Monte Carlo simulation model, consisting of Level 3 inputs not observable in the market, including estimates relating to revenue forecasts, discount rates and volatility.

For the three months ended June 30, 2024, we recognized income tax expense of $18 million, while for the six months ended June 30, 2024, we recognized an income tax benefit of $2 million. Our effective tax rate of (61.3)% for the three months ended June 30, 2024, differed from the statutory income tax rate primarily due to jurisdictional earnings mix of projected income in lower tax jurisdictions and losses in the U.S. and various foreign affiliates for which there was no tax benefit, as valuation allowances had been established in those countries. Our effective tax rate of 7.4% for the six months ended June 30, 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 and a benefit related to the recognition of certain state tax credits.
For the three and six months ended June 30, 2023, we recognized income tax expense of $18 million and $23 million, respectively. Our effective tax rates of (23.0)% and 79.9%, respectively, differed from the statutory income tax rates due to jurisdictional earnings mix of projected income in higher tax jurisdictions and losses in the U.S. and various foreign affiliates for which there was no tax benefit, as valuation allowances had been established in those countries.
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.

Note 13. Commitments and Contingencies
Legal Matters
We are party to various legal actions that 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.
Seresto Class Action Lawsuits
Claims seeking actual damages, injunctive relief and/or restitution for allegedly deceptive marketing have been made against Elanco Animal Health Inc. and Bayer HealthCare LLC, along with other Elanco and Bayer entities, arising out of the use of Seresto™, a non-prescription flea and tick collar for cats and dogs. During 2021, putative class action lawsuits were filed in federal courts in the U.S. alleging that the Seresto collars contain pesticides that can cause serious injury and death to cats and/or dogs wearing the product. In August 2021, the lawsuits were consolidated by the Judicial Panel on Multidistrict Litigation, and the cases were transferred to the Northern District of Illinois. In June 2023, the parties agreed on the monetary terms of a potential settlement of the consolidated class action lawsuits, and as a result, a charge of $15 million was recorded within Other expense, net in our condensed consolidated statements of operations for the three and six months ended June 30, 2023. As of December 31, 2023, the parties had agreed on the non-monetary terms of a potential settlement, in addition to the monetary terms agreed to in June 2023. In January 2024, the court preliminarily approved the settlement. The court set a hearing to consider final approval of the settlement in December 2024. If at that time all conditions of the settlement are met, and the settlement is approved, we anticipate the settlement amount will be payable in the first quarter of 2025. As
2024 Q2 Form 10-Q | 17
such, the $15 million provision was included within other current liabilities on our condensed consolidated balance sheet as of June 30, 2024.
Additional Legal Matters
For the legal matters discussed below, we either believe loss is not probable or are unable to 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 June 30, 2024 and December 31, 2023, we had no material liabilities established related to the legal matters discussed below.
On May 20, 2020, a shareholder class action lawsuit captioned Hunter v. Elanco Animal Health Inc., et al. (Hunter) was filed in the United States 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 United Stated Court of Appeals for the Seventh Circuit. We continue to believe the claims made in the case are meritless, and we intend to continue to vigorously defend our position.
On October 16, 2020, a shareholder class action lawsuit captioned Saffron 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 TEUs 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. The dismissal is without prejudice to plaintiffs' right to re-file a claim, and it is possible the plaintiffs will attempt to file a third amended complaint. We continue to believe the claims made in the case are meritless, and we intend 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. While it remains possible the plaintiff will appeal this decision, we continue to believe the claims made in the case are meritless, and in the event of any appeal, will continue to vigorously defend our position.
Regulatory Matters
On July 1, 2021, we received a subpoena from the SEC relating to our channel inventory and sales practices prior to mid-2020. We have engaged in discussions with the SEC about a possible resolution or settlement of potential disclosure claims, and in late July 2024 we reached an agreement in principle on terms of a potential settlement of disclosure claims, without admitting or denying the underlying allegations. We previously accrued a liability of $15 million, which was included within other current liabilities as of June 30, 2024, on our condensed consolidated balance sheet. The agreement remains subject to SEC approval and, therefore, it remains uncertain whether a definitive agreement will be reached and the terms of any such agreement.
2024 Q2 Form 10-Q | 18
Other Commitments
As of June 30, 2024, 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 us and the City of Indianapolis. 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 us and the developer, 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 included in other noncurrent liabilities on our condensed consolidated balance sheets and will be amortized over the lease term beginning on the commencement date and offset future rent expense.

Note 14. Earnings Per Share
We compute basic earnings per share by dividing net income available to common shareholders by the actual 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. We also had variable common stock equivalents related to the TEU prepaid stock purchase contracts in the first quarter of 2023 through the settlement date of February 1, 2023 (see Note 7. Equity for further discussion). 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 and that could have occurred if holders of unsettled TEUs had converted their holdings into common stock prior to the February 1, 2023 settlement date. 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:
Three Months Ended June 30,Six Months Ended June 30,
2024202320242023
Basic weighted-average common shares outstanding (1)

— — — 0.9 
Diluted weighted-average shares outstanding494.2 492.6 493.7 492.7
(1)The TEU prepaid stock purchase contracts were convertible into a minimum of 14.3 million shares or a maximum of 17.2 million shares. The minimum 14.3 million shares were included in the calculation of basic weighted-average shares from January 22, 2020 to February 1, 2023. The 17.2 million shares that were ultimately issued have been included in the calculation of basic weighted-average shares outstanding subsequent to the settlement date of February 1, 2023.
(2)For the three months ended June 30, 2024 and 2023, approximately 3.5 million and 2.0 million, respectively, of potential common shares were excluded from the calculation of diluted weighted-average shares outstanding because their effect was anti-dilutive. For the six months ended June 30, 2024 and 2023, approximately 3.5 million and 1.8 million, respectively, of potential common shares were excluded from the calculation of diluted weighted-average shares outstanding because their effect was anti-dilutive.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Introduction
Management’s discussion and analysis of financial condition and results of operations (MD&A) is intended to assist the reader in understanding and assessing significant changes and trends related to our results of operations and financial position. This discussion and analysis should be read in conjunction with the condensed consolidated financial statements and accompanying footnotes in Item 1 of Part I of this Form 10-Q. Certain statements in this Item 2 of Part I of this Form 10-Q constitute forward-looking statements. Various risks and uncertainties, including those discussed in “Forward-Looking Statements” of this Form 10-Q, in Item 1A, “Risk Factors” of Part II of this Form 10-Q and in Item 1A, “Risk Factors” of Part I of our 2023 Form 10-K, may cause our actual results, financial position and cash generated from operations to differ materially from these forward-looking statements. Further, due to the seasonality of our pet health sales, interim results are not necessarily an appropriate base from which to project annual results.
Business Overview
Elanco is a global leader in animal health, dedicated to innovating and delivering products and services to prevent and treat disease in farm animals and pets. Our diverse, durable product portfolio is sold in more than 90 countries and serves animals across many species, primarily: dogs and cats (collectively, pet health) and cattle, poultry, swine, sheep and aqua (collectively, farm animal). With a heritage dating back to 1954, we consistently innovate to improve the health of animals and to benefit our customers while fostering an inclusive, cause-driven culture for our employees. We operate our business in a single segment, directed at advancing the well-being of animals, people and the planet, enabling us to realize our vision of Food and Companionship Enriching Life.
Our diverse product portfolio of approximately 200 brands helps make us a trusted partner to pet owners, veterinarians and farm animal producers. Our products are generally sold worldwide to third-party distributors and independent retailers, and directly to farm animal producers and veterinarians. In recent years, we have expanded our omnichannel presence in both the veterinary clinic and in retail markets, including e-commerce.
Product Development and Regulatory Update
A key element of our targeted value creation strategy is to drive revenue growth through portfolio development and product innovation. We continue to pursue the development of new chemical and biological molecules, as well as additional registrations and indications for current products. Our future growth and success depend on both our pipeline of new products, including new products we develop internally, develop with partners or that we obtain through licenses or acquisitions, and the life cycle management of our existing products. We believe we are an industry leader in animal health R&D, with a track record of successful product innovation, business development and commercialization.
Bovaer: In May 2024, the U.S Food and Drug Administration (FDA) completed its comprehensive, multi-year review of Bovaer(R) (3-NOP), a first-in-class methane-reducing feed ingredient for use in lactating dairy cattle. We expect producers to begin feeding the product in the third quarter of 2024.
Zenrelia: In late July 2024, we received confirmation from the FDA that all major and minor technical sections for ZenreliaTM, a JAK inhibitor targeting control of pruritus and atopic dermatitis in dogs, are complete. Upon confirmation of all technical sections, we submitted the full New Animal Drug Application (NADA) for final administrative review, which is expected to be complete in 60 days, culminating in final FDA approval for Zenrelia in late September 2024. We currently expect to launch Zenrelia in October 2024 with a box warning. We have also received approval for Zenrelia in Brazil, with expected launch in the second half of 2024, and additional reviews are ongoing in other key markets, including Europe, United Kingdom, Australia, Canada and Japan.
Other Key Trends and Factors Affecting Our Results of Operations
Aqua Business Divestiture: On July 9, 2024, we closed the sale of our aqua business to a subsidiary of Merck Animal Health, for approximately $1.3 billion in cash, which was paid at closing. Our aqua business included products across both warm-water and cold-water species and generated revenues of $80 million and $90 million during the six months ended June 30, 2024 and 2023, respectively. 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. Along with these assets, approximately 280 commercial and manufacturing employees were transferred to Merck Animal Health as part of this divestiture.
While the accounting for the aqua sale is not yet complete, we expect to record a pre-tax gain on divestiture of approximately $630 million to $660 million during the third quarter of 2024. Income tax expense associated with this divestiture is expected to be in the range of $170 million to $190 million. Upon receipt of the sales proceeds, we paid down $1,222 million in term debt, reducing our leverage and future interest expense. Strategically, this
2024 Q2 Form 10-Q | 20
divestiture allows us to prioritize our investments in larger markets with greater long-term earnings potential. See Note 4. Acquisitions, Divestitures and Other Arrangements to the condensed consolidated financial statements for further information.
Restructuring Activities: In February 2024, our Board of Directors authorized a restructuring plan (the restructuring plan) to improve operational efficiencies and better align our organizational structure with current business needs, top strategic priorities and key growth opportunities. Specifically, the restructuring plan was intended to reallocate resources by shifting international resources from farm animal to pet health as we plan for the global launches of certain blockbuster potential products currently under regulatory review. Further, the restructuring plan impacted how we operate in and sell into the Argentina market, among others, reducing our foreign currency exposure in those markets.
Total expected pre-tax charges associated with the restructuring plan total $50 to $55 million in 2024, of which $43 million was incurred during the six months ended June 30, 2024, the majority relating to cash-based severance costs. The restructuring plan is expected to result in annualized net savings of $30 to $35 million. See Note 5. Asset Impairment, Restructuring and Other Special Charges to the condensed consolidated financial statements for further information.
Acquisition and Integration Activity: In April 2023 we successfully completed the integration of the Bayer Animal Health business into our enterprise resource planning (ERP) system. We incurred costs totaling $93 million in 2023 related to integration activities, including the build out of processes and systems to support our global organization. In connection with this integration, we notified our customers of an expected commercial blackout period during specified periods of time in April 2023, during which certain products would not be able to be shipped. Due to this, we believe certain customers modified their purchasing habits, causing a shift of revenue from the second quarter of 2023 to the first quarter of 2023 of approximately $90 million to $110 million, based on our high-level estimates. While first quarter 2023 revenue benefited from this shift in purchases, this resulted in a corresponding decrease in revenue during the second quarter of 2023.
Macroeconomic Factors: As a global company with products sold in more than 90 countries, our operations are exposed to and are impacted by various global macroeconomic factors. We face continuing market and operating challenges across the globe due to, among other factors, the Russia-Ukraine conflict, conditions related to supply chain disruption, higher interest rates, foreign currency exchange rate volatility and inflationary pressures. Continued evolution of these conditions has led to economic slowdowns in certain countries and/or regions and volatility in consumer behavior. We anticipate global macroeconomic pressures to continue throughout 2024.
Seasonality: While many of our products are sold consistently throughout the year, we do experience seasonality in our pet health business due to increased demand for certain parasiticide product offerings in the first half of the year. For example, based upon historical results, approximately 75% and 60% of total annual revenue contributed by our higher-margin parasiticide products Seresto and Advantage Family, respectively, typically occurs during the first half of the year, which is reflective of the flea and tick season in the Northern Hemisphere.

Results of Operations
The following discussion and analysis of our results of operations should be read along with our condensed consolidated financial statements and the notes thereto. Our results of operations for the periods presented below may not be comparable with prior periods or with our results of operations in the future due to many factors, including but not limited to the factors identified above.

Revenue
As a global company, our products are sold in more than 90 countries, and as a result, a significant portion of our revenue is recorded in currencies other than the U.S. Dollar. Because of this, our revenue is influenced by changes in foreign currency exchange rates. During the six months ended June 30, 2024 and 2023, approximately 54% of our revenue was denominated in foreign currencies.
Further, increases or decreases in inventory levels in our distribution channels can positively or negatively impact our quarterly revenue results, leading to variations in revenue. This can be a result of various factors, such as end customer demand, new customer contracts, heightened and generic competition, the need for certain inventory levels, our ability to renew distribution contracts with expected terms, our ability to implement commercial strategies, regulatory restrictions, unexpected customer behavior, proactive measures taken by us in response to shifting market dynamics, payment terms we extend, which are subject to internal policies, blackout shipping periods due to system downtime, implementations and integrations and procedures and environmental factors beyond our control. For example, in connection with the integration of the Bayer Animal Health business into our ERP system, we communicated commercial shipping blackout periods that occurred in April 2023. Given this timing, we believe certain customers modified purchasing habits, which we estimate caused a shift of revenue from the second quarter of 2023 to the first quarter of 2023 of approximately $90 million to $110 million. While first quarter 2023 revenue benefited from this shift in purchases, this resulted in a corresponding decrease in revenue during the second quarter of 2023. This estimated shift of quarterly revenue in the prior year is a principal contributor to the year-over-year volume increases experienced during the three months ended June 30, 2024.
On a global basis, our revenue by product category for the three and six months ended June 30, 2024 and 2023, was as follows:

(1)Constant Currency (CC), a non-GAAP measure, is defined as revenue growth excluding the impact of foreign exchange rates. The calculation assumes the same foreign currency exchange rates that were in effect for the comparable prior-year period were used in translation of the current period results. We believe this metric provides a useful comparison to previous periods.
(2)Represents revenue from arrangements in which we manufacture products on behalf of a third-party.
On a global basis, the effects of price, foreign currency exchange rates and volume on changes in revenue for the three and six months ended June 30, 2024, compared to the three and six months ended June 30, 2023, were as follows:

Pet health revenue increased $61 million, or 12%, for the three months ended June 30, 2024, compared to the same period in 2023, driven by higher volumes and a 3% increase in pricing. The primary driver of the higher volumes was the impact of the ERP system integration commercial blackout periods in the prior year, which we believe shifted an estimated $65 million to $80 million in pet health revenue from the second quarter of 2023 to the first quarter of 2023, and to a lesser degree, increased sales of new products and improved demand for retail parasiticide products in certain European markets, including Spain. These increases were partially offset by continued competitive pressure on certain products in the U.S. veterinary channel and purchasing patterns of certain over-the-counter (OTC) products by U.S. retailers.
Pet health revenue increased $25 million, or 2%, for the six months ended June 30, 2024, compared to the same period in 2023, driven by a 3% increase in pricing. Volumes during the six months ended June 30, 2024 were slightly lower due to continued competitive pressure on certain products in the U.S. veterinary channel and purchasing patterns of certain OTC products by U.S. retailers. These decreases were partially offset by increased vaccine sales due to easing of supply constraints, increased sales of new products, improved demand for retail parasiticide products in certain European markets, including Spain, and the impact of an initial stocking of certain legacy Bayer Animal Health products into the U.S. veterinary distribution channel during the first quarter of 2024.
Farm animal revenue increased $67 million, or 13%, for the three months ended June 30, 2024, compared to the same period in 2023, driven by higher volumes and a 4% increase in pricing. The primary driver of the higher volumes was the impact of the ERP system integration commercial blackout periods in the prior year, which we believe shifted an estimated $25 million to $30 million of revenue from the second quarter of 2023 to the first quarter of 2023, as well as increased revenue from new products, led by Experior, increased cattle vaccine sales due to easing of supply constraints and strength in poultry sales globally. These factors were partially offset by declines in certain aqua products.
Farm animal revenue increased $50 million, or 5%, for the six months ended June 30, 2024, compared to the same period in 2023, driven by higher volumes and a 2% increase in pricing. The higher volumes were primarily driven by increased revenue from new products, led by Experior, increased cattle vaccine sales due to easing of supply

Gross margin was unfavorably impacted during the three months ended June 30, 2024, compared to the prior year, by a combination of inflation and planned reduced throughput at certain manufacturing sites in support of efforts to reduce inventory balances and improve cash conversion. These factors were partially offset by favorable product mix due to the larger impact of the ERP system integration commercial blackout periods during the prior year on higher margin products and increased pricing.
Cost of sales increased $82 million for the six months ended June 30, 2024, compared to the six months ended June 30, 2023, and cost of sales as a percentage of revenue increased to 42%, compared to 40% for the prior year period. These increases were due to a combination of inflation and planned reduced throughput at certain manufacturing sites in support of efforts to reduce inventory balances and improve cash conversion, partially offset by increased pricing.

Asset impairment, restructuring and other special charges increased $45 million and $51 million for the three and six months ended June 30, 2024, respectively, as compared to the same periods in the prior year. Amounts recorded during the three months ended June 30, 2024, principally reflected a $53 million impairment charge related to a pet health IPR&D asset that was acquired from Kindred Biosciences, Inc. in 2021 (IL-4R). In June 2024, we completed required studies for IL-4R, and while no adverse events were reported, the performance of the product did not meet efficacy expectations to attain commercial viability. Due to this, future R&D activities were terminated, and the IPR&D asset was written off. Asset impairment, restructuring and other special charges during the three and six months ended June 30, 2024, also included $10 million and $17 million, respectively, of transaction costs associated with the divestiture of our aqua business. Amounts recorded during the six months ended June 30, 2024, also included $43 million of costs associated with our restructuring plan announced in February 2024.
Amounts recorded during the three and six months ended June 30, 2023, primarily represented costs associated with the implementation of new systems, programs, and processes due to the integration of Bayer Animal Health.

We recognized income tax expense of $18 million for both the three months ended June 30, 2024, and 2023. Our effective tax rate of (61.3)% for the three months ended June 30, 2024, differed from the statutory income tax rate primarily due to jurisdictional earnings mix of projected income in lower tax jurisdictions and losses in the U.S. and various foreign affiliates for which there was no tax benefit, as valuation allowances had been established in those countries. Our effective tax rate of (23.0)% for the three months ended June 30, 2023, differed from the statutory income tax rate primarily due to jurisdictional earnings mix of projected income in higher tax jurisdictions and losses in the U.S. and various foreign affiliates for which there was no tax benefit, as valuation allowances had been established in those countries.
We recognized an income tax benefit of $2 million for the six months ended June 30, 2024, compared to income tax expense of $23 million for the same period in the prior year. The income tax benefit during the six months ended June 30, 2024, was primarily driven by the partial release of a valuation allowance attributable to the anticipated sale of our aqua business and a benefit related to the recognition of certain state tax credits. Our effective tax rate of 79.9% for the six months ended June 30, 2023, differed from the statutory income tax rates due to jurisdictional

Liquidity and Capital Resources
Our primary sources of liquidity are cash on hand, cash flows from operations and funds available under our credit facilities. As a significant portion of our business is conducted internationally, we hold a significant portion of cash outside of the U.S. We monitor and adjust the amount of foreign cash based on projected cash flow requirements. Our ability to use foreign cash to fund cash flow requirements in the U.S. may be impacted by local regulations and, to a lesser extent, the income taxes associated with transferring cash to the U.S. We intend to indefinitely reinvest substantially all foreign earnings for continued use in our foreign operations. As our business evolves, we may change that strategy, particularly to the extent we identify tax-efficient reinvestment alternatives for our foreign earnings or change our cash management strategy.
We believe our primary sources of liquidity are sufficient to fund our short-term and long-term existing and planned capital requirements, which include working capital obligations, funding existing marketed and pipeline products, capital expenditures, business development in our targeted areas, short-term and long-term debt obligations, such as principal and interest payments, as well as interest rate swaps, operating lease payments, purchase obligations and costs associated with mergers, acquisitions, divestitures and business integrations and/or restructuring activities. As of June 30, 2024, we had cash and cash equivalents of $416 million and unused borrowing capacity on our Revolving Credit Facility of approximately $750 million. On July 3, 2024, we amended our Revolving Credit Facility, extending its availability through July 2029. Also, following the sale of our aqua business, we utilized $1,222 million of cash proceeds to pay down term loan debt, significantly reducing our leverage and future interest expense. In addition, our Securitization Facility provides additional borrowing capacity in the event our borrowing capacity on this facility, which is correlated to our U.S. Net Eligible Receivables Balances, exceeds our outstanding borrowings on the facility, although as of June 30, 2024, we had no undrawn borrowing capacity on our Securitization Facility. We also have the ability to access capital markets to obtain debt financing for longer-term funding, if required. Further, we believe we have sufficient cash flow and liquidity to remain in compliance with our debt covenants.
Our ability to meet future funding requirements may be impacted by macroeconomic, business and financial volatility. As market conditions change, we will continue to monitor our liquidity position. However, a challenging economic environment or an economic downturn may impact our liquidity or ability to obtain future financing. See "Item 1A. Risk Factors - We have substantial indebtedness" in Part I of our 2023 Form 10-K.

Cash provided by financing activities of $213 million during the six months ended June 30, 2023, primarily reflected proceeds from our Revolving Credit Facility, partially offset by the repayment of indebtedness outstanding under our long-term borrowings.
Description of Indebtedness
For a complete description of our existing debt and available credit facilities as of June 30, 2024 and December 31, 2023, see Note 8. Debt within Item 8, “Financial Statements and Supplementary Data,” of Part II of our 2023 Form 10-K. New developments, including the amendment to our Revolving Credit Facility and $1,222 million pay down of our term loan debt following the sale of our aqua business are discussed in Note 8. Debt of this Form 10-Q.
Critical Accounting Policies and Estimates
The preparation of financial statements in accordance with U.S. GAAP requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses. Certain of our accounting policies are considered critical because these policies are the most important to the depiction of our financial statements and require significant, difficult or complex judgments, often requiring the use of estimates about the effects of matters that are inherently uncertain. Actual results that differ from our estimates could have an unfavorable effect on our financial position and results of operations. We apply estimation methodologies consistently from year to year. Such policies are summarized in Item 7, "Management's Discussion & Analysis of Results of Financial Condition and Results of Operations," of our 2023 Form 10-K. There were no significant changes or developments in the application of our critical accounting policies during the six months ended June 30, 2024.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
Foreign Exchange Risk
We operate on a global basis and are exposed to the risk that our earnings, cash flows and equity could be adversely impacted by fluctuations in foreign currency exchange rates. We are exposed to foreign currency exchange risk as the functional currency financial statements of non-U.S. subsidiaries are translated to U.S. dollars. We are also subject to foreign currency transaction gains and losses to the extent revenue and expense transactions are not denominated in the functional currency of a subsidiary. We are primarily exposed to foreign currency exchange risk with respect to net assets denominated in the Euro, British pound, Swiss franc, Brazilian real, Australian dollar, Japanese yen, Canadian dollar and Chinese yuan.
Additionally, we generally identify hyperinflationary markets as those markets whose cumulative inflation rate over a three-year period exceeds 100%. We have applied hyperinflationary accounting for our Argentina and Turkey subsidiaries since 2018 and 2022, respectively, and as a result, have changed their functional currencies to the U.S. dollar. During the six months ended June 30, 2024, revenue in Argentina and Turkey each represented less than 1% of our consolidated revenue, and assets held in Argentina and Turkey as of June 30, 2024, each represented less than 1% of our consolidated assets. Further, in February 2024 our Board of Directors authorized a restructuring plan that, among other strategic decisions, has resulted in a change in how we operate in and sell into the Argentina market, which has reduced our foreign currency exposure with respect to the Argentine peso. In spite of this, and while the application of hyperinflationary accounting for our subsidiaries in Argentina and Turkey did not have a material impact on our business during the six months ended June 30, 2024, we may in the future incur further currency devaluations, which could have a material adverse impact on our results of operations.
Interest Risk
At June 30, 2024, we held interest rate swap agreements with a notional value of $3,800 million that had the economic effect of modifying this amount of our variable-rate debt to fixed-rate. Following the sale of our aqua business and the associated debt pay down, we settled $1,000 million notional amount of these interest rate swaps (see Note 9. Financial Instruments for additional information). When including variable-rate converted to fixed-rate through the use of interest rate swaps, and subsequent to the debt pay down and interest rate swap settlements, approximately 79% of our long-term indebtedness bears interest at a fixed rate.

ITEM 4. CONTROLS AND PROCEDURES
(a)Evaluation of Disclosure Controls and Procedures. Under applicable SEC regulations, management of a reporting company, with the participation of the principal executive officer and principal financial officer, must periodically evaluate the company’s “disclosure controls and procedures,” which are defined generally as controls and other procedures of a reporting company designed to ensure that information required to be disclosed by the reporting company in its periodic reports filed with the SEC (such as this Form 10-Q) is recorded, processed, summarized and reported on a timely basis.
Our management, with the participation of Jeffrey N. Simmons, president and chief executive officer, and Todd S. Young, executive vice president and chief financial officer, evaluated our disclosure controls and procedures as of June 30, 2024, and concluded they were effective.
(b)Changes in Internal Controls. During the second quarter of 2024, there were no changes in our internal control over financial reporting that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

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, 2023, included in our 2023 Form 10-K. 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, 2024, or any other future period.
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. In preparing financial statements in conformity with GAAP, we must make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, expenses and related disclosures at the date of the financial statements and during the reporting period. Actual results could differ from those estimates. Certain reclassifications of prior year information have been made to conform to the current year's presentation.
The significant accounting policies set forth in Note 2 to the consolidated financial statements in our 2023 Form 10-K and the footnotes herein appropriately represent, in all material respects, the current status of our accounting policies.

Revenue from Contract with Customer [Abstract]  
Revenue
Note 3. Revenue
We recognize revenue primarily from product sales to customers. Revenue from sales of products is recognized at the point where the customer obtains control of the goods and we satisfy our performance obligations, which is generally once the goods have been shipped and the customer has assumed title. For contract manufacturing organization (CMO) arrangements, we recognize revenue over time or at a point in time depending on our evaluation of when the customer obtains control of the promised goods or services.
Provisions for sales rebates and discounts are recorded as a reduction to revenue in the period the related sales are recognized and are based on specific agreements. In determining the appropriate accrual amount, we consider our historical experience with similar incentive programs, current sales data and estimates of inventory levels at our channel distributors. The following table summarizes the activity in our global sales rebates and discounts liability:

Adjustments to revenue recognized due to changes in estimates for products shipped in previous periods were not material for either the six months ended June 30, 2024 or 2023. Actual global product returns were approximately 1% of net revenue for the six months ended June 30, 2024 and 2023.

Acquisitions
During 2023, we completed the acquisitions of certain U.S. marketed products, pipeline products, inventory and an assembled workforce from NutriQuest, LLC (NutriQuest) and certain assets including inventory and distribution rights for certain marketed products from NutriQuest Nutricao Animal Ltda (NutriQuest Brazil). Each of these transactions was accounted for as a business combination under the acquisition method of accounting. The acquisition method requires, among other things, that assets acquired and liabilities assumed be recognized at their fair values as of the acquisition date. The determination of estimated fair value requires management to make significant estimates and assumptions. The excess of the purchase price over the fair value of the acquired net assets, where applicable, has been recorded as goodwill.
NutriQuest
On January 3, 2023, we acquired NutriQuest for total purchase consideration of $59 million. NutriQuest is a provider of swine, poultry and cattle nutritional health products to animal producers. The acquisition helped us expand our
existing nutritional health offerings and further our efforts to explore innovative antibiotic alternatives. The composition of the purchase price was as follows:
Up-front cash consideration$16 
Deferred cash consideration paid January 4, 20245 
Fair value of contingent consideration38 
Total purchase consideration$59 
Contingent consideration for this acquisition includes up to $85 million of cash consideration payable if specific development, sales and geographic expansion milestones are achieved, as outlined in the asset purchase agreement. The initial fair value of this contingent consideration liability of $38 million was estimated at the acquisition date using a Monte Carlo simulation model, which represented a Level 3 measurement under the fair value hierarchy (see Note 10. Fair Value for further information).
The following table summarizes the fair values of assets acquired as of the acquisition date:

Other intangible assets consist of customer relationships and trade names. The acquired definite-lived intangible assets are being amortized over a weighted-average estimated useful life of approximately 12 years on a straight-line basis.
NutriQuest Brazil
On August 1, 2023, we acquired NutriQuest Brazil for total purchase consideration of $19 million. The composition of the purchase price included cash paid on the closing date of $3 million, with additional consideration payable through 2026 valued at approximately $16 million, a portion of which is contingent upon the continuation of certain terms and conditions set forth in the asset purchase agreement.
The following table summarizes the fair values of assets acquired as of the acquisition date:

Divestitures
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 approximately $1.3 billion in cash. Following the close, we used proceeds from this sale to repay $1,222 million of term loan debt (see Note 8. Debt for further information). Our aqua business included products across both warm-water and cold-water species and generated revenues of $80 million and $90 million during the six months ended June 30, 2024 and 2023, respectively. Given that we operate our business as a single reporting unit, we are unable to reasonably determine stand-alone costs and related earnings or loss before income taxes attributable to our aqua business. 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. Along with these assets, approximately 280 commercial and manufacturing employees were transferred to Merck Animal Health as part of this divestiture.
We determined the aqua business assets sold (the disposal group) met all the required criteria to be classified as held for sale in February 2024. Accordingly, at that time we ceased depreciation and amortization of the long-lived assets included within the disposal group. Given the closing of the transaction on July 9, 2024, these assets remained classified as held for sale on our condensed consolidated balance sheet as of June 30, 2024. We also
determined that the sale of our aqua business did not qualify for reporting as a discontinued operation, as it did not represent a strategic shift that will have a major effect on our operations and/or financial results.
While the accounting for the aqua sale is not yet complete, we expect to record a pre-tax gain on divestiture of approximately $630 million to $660 million during the third quarter of 2024. In establishing the carrying value of our disposal group, a portion of our single reporting unit’s goodwill was allocated to the disposal group on a relative fair value basis. In determining the relative fair value of the disposal group to our single reporting unit as a whole, we compared the fair value of the disposal group to an estimated fair value of our single reporting unit, which was based on a fair value assessment using the income approach. The income approach is a valuation technique that provides an estimate of fair value based on market participant expectations of the cash flows an asset would generate over its remaining useful life. Significant management judgment was required in estimating the fair value of our single reporting unit, including, but not limited to, estimates and assumptions regarding future cash flows of our single reporting unit, revenue growth and other profitability measures, such as gross margin and earnings before interest, taxes, depreciation and amortization (EBITDA) margin, and the determination of an appropriate discount rate. We consider this valuation approach to be a Level 3 measurement under the fair value hierarchy.
As of June 30, 2024, the carrying amounts of the following major assets were classified as held for sale on our condensed consolidated balance sheet:
Inventories$43 
Goodwill458 
Other intangibles, net50 
Property and equipment, net68 
Other assets8 
Total assets held for sale$627 
Shawnee and Speke
In August 2021 and February 2022, we completed the sales of our Shawnee, Kansas and Speke, U.K. sites, respectively to TriRx Pharmaceuticals (TriRx). Based on the original terms of the sales agreements, we anticipated receiving cash consideration from TriRx over a three-year period, and we received cash proceeds of $13 million from TriRx in 2022. In May 2023, we entered into amendments to the agreements (the amended agreement), which effectively restructured the payment schedule related to the remaining amount owed. At December 31, 2023, our remaining net receivable balance from TriRx under the amended agreement was $69 million. In February 2024, we received $66 million, in addition to accrued interest. The final $3 million was due from TriRx on August 1, 2024. While this amount has not yet been paid, based on our current assessment, we continue to believe this amount is collectible.

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 product, facility and business rationalizations and workforce reductions. We have also incurred costs associated with executing acquisition, divestiture and other significant transactions and related integration and/or separation activities.

(1)Restructuring charges in 2024 primarily related to expected 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 directly related to the recent divestiture of our aqua business (see Note 4. Acquisitions, Divestitures and Other Arrangements for further information). Acquisition and divestiture-related charges
in 2023 primarily represented costs associated with the implementation of new systems, programs and processes due to the integration of Bayer Animal Health.
(3)Asset impairments principally reflected the write-off of our IL-4R IPR&D asset ($53 million), which was acquired from Kindred Biosciences, Inc. in 2021. In June 2024, we completed required studies for IL-4R, and while no adverse events were reported, the performance of the product did not meet efficacy expectations to attain commercial viability. As such, future research and development activities were terminated and the IPR&D asset was written-off.

Derivative Instruments and Hedging Activities Disclosure [Abstract]  
Financial Instruments
Note 9. Financial Instruments
To manage our exposure to market risks, such as changes in foreign currency exchange rates and interest rates, we have entered into various derivative transactions. We formally assess, designate and document, as a hedge of an underlying exposure, each qualifying derivative instrument that will be accounted for as an accounting hedge at inception. We also assess at least quarterly thereafter whether the financial instruments used in the hedging transaction are effective at offsetting changes in either the fair values or cash flows of the underlying exposures. Derivative cash flows are principally classified in the operating activities section of the condensed consolidated statements of cash flows, consistent with the underlying hedged item. Further, we do not offset derivative assets and liabilities on the condensed consolidated balance sheets.
Derivatives not designated as hedges
We may enter into foreign exchange forward or option contracts to reduce the effect of fluctuating foreign currency exchange rates. Foreign currency derivatives used for hedging are put in place using the same or like currencies and duration as the underlying exposures and are recorded at fair value with the gain or loss recognized in other expense, net in the condensed consolidated statements of operations. Forward contracts generally have maturities not exceeding 12 months. As of June 30, 2024 and December 31, 2023, we had outstanding foreign exchange contracts with aggregate notional amounts of $1,015 million and $891 million, respectively.
The amounts of net gains (losses) on derivative instruments not designated as hedging instruments, recorded in other expense, net were as follows:
Three Months Ended June 30,Six Months Ended June 30,

Foreign exchange forward contracts (1)
$3 $(1)$(6)$1 
(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
In September 2023 we entered into 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. These instruments were determined to be, and were designated as, effective economic hedges of net investments in our CHF denominated net assets. The fair values of these instruments were estimated based on quoted market values of similar hedges and are classified as Level 2 in the fair value hierarchy (see Note 10. Fair Value for further information). Gains or losses related to these instruments due to spot rate fluctuations are recorded as cumulative translation adjustments as a component of other comprehensive income (loss). Gains and losses will remain in accumulated other comprehensive income (loss) until either the sale or substantial liquidation of the hedged subsidiary. (Losses) gains on net investment hedges, net of tax, recorded in other comprehensive (loss) income, were as follows:

2024202320242023
Cross-currency fixed interest rate swaps$(10)$— $52 $— 
During the six months ended June 30, 2024, these instruments also generated $15 million of interest income, 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
To manage our exposure to variable interest rate risk, we utilize interest rate swap contracts to effectively convert our variable-rate debt into fixed-rate debt. We recognize any differences between the variable interest rate payments and the fixed interest rate settlements with the swap counterparties as an adjustment to interest expense, net of capitalized interest over the life of the swaps. We have designated our interest rate swaps as cash flow hedges and record them at fair value on the condensed consolidated balance sheets. Changes in the fair value of the hedges are recognized in other comprehensive income (loss) and reclassified into earnings through interest expense, net of capitalized interest at the time earnings are affected by the hedged transaction. Fair value is estimated based on quoted market values of similar hedges and is classified as Level 2 in the fair value hierarchy.
We had outstanding interest rate swaps, with aggregate notional amounts of $3,800 million as of both June 30, 2024 and December 31, 2023. As of June 30, 2024, our interest rate swap instruments had maturities ranging between 2026 and 2028. The amounts of gains on our interest rate swap contracts, net of tax, recorded in other comprehensive (loss) income were as follows:

Interest rate swaps$30 $30 $61 $60 
Following the sale of our aqua business and the associated debt pay down (see Note 4. Acquisitions, Divestitures and Other Arrangements and Note 8. Debt for further information), we also settled $1,000 million of existing interest rate swaps, which reduced the aggregate notional amount of our interest rate swaps to $2,800 million. We received cash proceeds of approximately $5 million upon these settlements, which will be recorded in accumulated other comprehensive loss during the third quarter of 2024 and amortized to interest expense, net of capitalized interest over the original term of the interest rate swaps. Subsequent to these settlements, all remaining interest rate swaps have scheduled maturities in 2026. Over the next 12 months, we expect to reclassify a gain of $84 million from accumulated other comprehensive loss into interest expense, net of capitalized interest related to our current and previously settled interest rate swaps.
When factoring in the above noted $1,222 million debt pay down and the related $1,000 million swap settlement, the weighted-average effective interest rate on our outstanding indebtedness was 6.47% (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 10. 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 June 30, 2024 and December 31, 2023, 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 a reasonable estimate of their fair values due to the short-term nature of these assets and liabilities. We also had investments without readily determinable fair values and equity method investments, which were classified as other noncurrent assets on our condensed consolidated balance sheets totaling $24 million and $26 million as of June 30, 2024 and December 31, 2023, 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.
The fair values of contingent consideration liabilities related to our acquisition of NutriQuest were estimated using the Monte Carlo simulation model, consisting of Level 3 inputs not observable in the market, including estimates relating to revenue forecasts, discount rates and volatility.

For the three months ended June 30, 2024, we recognized income tax expense of $18 million, while for the six months ended June 30, 2024, we recognized an income tax benefit of $2 million. Our effective tax rate of (61.3)% for the three months ended June 30, 2024, differed from the statutory income tax rate primarily due to jurisdictional earnings mix of projected income in lower tax jurisdictions and losses in the U.S. and various foreign affiliates for which there was no tax benefit, as valuation allowances had been established in those countries. Our effective tax rate of 7.4% for the six months ended June 30, 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 and a benefit related to the recognition of certain state tax credits.
For the three and six months ended June 30, 2023, we recognized income tax expense of $18 million and $23 million, respectively. Our effective tax rates of (23.0)% and 79.9%, respectively, differed from the statutory income tax rates due to jurisdictional earnings mix of projected income in higher tax jurisdictions and losses in the U.S. and various foreign affiliates for which there was no tax benefit, as valuation allowances had been established in those countries.
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.

Commitments and Contingencies
Note 13. Commitments and Contingencies
Legal Matters
We are party to various legal actions that 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.
Seresto Class Action Lawsuits
Claims seeking actual damages, injunctive relief and/or restitution for allegedly deceptive marketing have been made against Elanco Animal Health Inc. and Bayer HealthCare LLC, along with other Elanco and Bayer entities, arising out of the use of Seresto™, a non-prescription flea and tick collar for cats and dogs. During 2021, putative class action lawsuits were filed in federal courts in the U.S. alleging that the Seresto collars contain pesticides that can cause serious injury and death to cats and/or dogs wearing the product. In August 2021, the lawsuits were consolidated by the Judicial Panel on Multidistrict Litigation, and the cases were transferred to the Northern District of Illinois. In June 2023, the parties agreed on the monetary terms of a potential settlement of the consolidated class action lawsuits, and as a result, a charge of $15 million was recorded within Other expense, net in our condensed consolidated statements of operations for the three and six months ended June 30, 2023. As of December 31, 2023, the parties had agreed on the non-monetary terms of a potential settlement, in addition to the monetary terms agreed to in June 2023. In January 2024, the court preliminarily approved the settlement. The court set a hearing to consider final approval of the settlement in December 2024. If at that time all conditions of the settlement are met, and the settlement is approved, we anticipate the settlement amount will be payable in the first quarter of 2025. As
such, the $15 million provision was included within other current liabilities on our condensed consolidated balance sheet as of June 30, 2024.
Additional Legal Matters
For the legal matters discussed below, we either believe loss is not probable or are unable to 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 June 30, 2024 and December 31, 2023, we had no material liabilities established related to the legal matters discussed below.
On May 20, 2020, a shareholder class action lawsuit captioned Hunter v. Elanco Animal Health Inc., et al. (Hunter) was filed in the United States 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 United Stated Court of Appeals for the Seventh Circuit. We continue to believe the claims made in the case are meritless, and we intend to continue to vigorously defend our position.
On October 16, 2020, a shareholder class action lawsuit captioned Saffron 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 TEUs 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. The dismissal is without prejudice to plaintiffs' right to re-file a claim, and it is possible the plaintiffs will attempt to file a third amended complaint. We continue to believe the claims made in the case are meritless, and we intend 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. While it remains possible the plaintiff will appeal this decision, we continue to believe the claims made in the case are meritless, and in the event of any appeal, will continue to vigorously defend our position.
Regulatory Matters
On July 1, 2021, we received a subpoena from the SEC relating to our channel inventory and sales practices prior to mid-2020. We have engaged in discussions with the SEC about a possible resolution or settlement of potential disclosure claims, and in late July 2024 we reached an agreement in principle on terms of a potential settlement of disclosure claims, without admitting or denying the underlying allegations. We previously accrued a liability of $15 million, which was included within other current liabilities as of June 30, 2024, on our condensed consolidated balance sheet. The agreement remains subject to SEC approval and, therefore, it remains uncertain whether a definitive agreement will be reached and the terms of any such agreement.
Other Commitments
As of June 30, 2024, 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 us and the City of Indianapolis. 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 us and the developer, 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 included in other noncurrent liabilities on our condensed consolidated balance sheets and will be amortized over the lease term beginning on the commencement date and offset future rent expense.

Earnings Per Share [Abstract]  
Earnings Per Share
Note 14. Earnings Per Share
We compute basic earnings per share by dividing net income available to common shareholders by the actual 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. We also had variable common stock equivalents related to the TEU prepaid stock purchase contracts in the first quarter of 2023 through the settlement date of February 1, 2023 (see Note 7. Equity for further discussion). 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 and that could have occurred if holders of unsettled TEUs had converted their holdings into common stock prior to the February 1, 2023 settlement date. 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:

— — — 0.9 
Diluted weighted-average shares outstanding494.2 492.6 493.7 492.7
(1)The TEU prepaid stock purchase contracts were convertible into a minimum of 14.3 million shares or a maximum of 17.2 million shares. The minimum 14.3 million shares were included in the calculation of basic weighted-average shares from January 22, 2020 to February 1, 2023. The 17.2 million shares that were ultimately issued have been included in the calculation of basic weighted-average shares outstanding subsequent to the settlement date of February 1, 2023.
(2)For the three months ended June 30, 2024 and 2023, approximately 3.5 million and 2.0 million, respectively, of potential common shares were excluded from the calculation of diluted weighted-average shares outstanding because their effect was anti-dilutive. For the six months ended June 30, 2024 and 2023, approximately 3.5 million and 1.8 million, respectively, of potential common shares were excluded from the calculation of diluted weighted-average shares outstanding because their effect was anti-dilutive.

Organization, Consolidation and Presentation of Financial Statements [Abstract]  
Basis of Presentation
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, 2023, included in our 2023 Form 10-K. 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, 2024, or any other future period.
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. In preparing financial statements in conformity with GAAP, we must make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, expenses and related disclosures at the date of the financial statements and during the reporting period. Actual results could differ from those estimates. Certain reclassifications of prior year information have been made to conform to the current year's presentation.

(1)Restructuring charges in 2024 primarily related to expected 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 directly related to the recent divestiture of our aqua business (see Note 4. Acquisitions, Divestitures and Other Arrangements for further information). Acquisition and divestiture-related charges
in 2023 primarily represented costs associated with the implementation of new systems, programs and processes due to the integration of Bayer Animal Health.
(3)Asset impairments principally reflected the write-off of our IL-4R IPR&D asset ($53 million), which was acquired from Kindred Biosciences, Inc. in 2021. In June 2024, we completed required studies for IL-4R, and while no adverse events were reported, the performance of the product did not meet efficacy expectations to attain commercial viability. As such, future research and development activities were terminated and the IPR&D asset was written-off.
