(1) During the three months ended March 31, 2024, we sold all of our available-for-sale debt securities and used the proceeds to partially fund our acquisition of CymaBay Therapeutics, Inc. (“CymaBay”) discussed in Note 6. Acquisitions, Collaborations and Other Arrangements.

(2) Publicly traded equity securities include investments in Galapagos NV (“Galapagos”) of $417 million and Arcellx, Inc. (“Arcellx”) of $371 million as of June 30, 2024, which are subject to contractual sale restrictions until August 2024 and June 2025, respectively.

Level 2 Inputs

Available-for-Sale Debt Securities

For our available-for-sale debt securities, we estimate the fair values by reviewing trading activity and pricing as of the measurement date and by taking into consideration valuations obtained from third-party pricing services. The pricing services utilize industry standard valuation models, including both income-based and market-based approaches, for which all significant inputs are observable, either directly or indirectly, to estimate the fair value. These inputs include reported trades of and broker/dealer quotes on the same or similar securities, issuer credit spreads, benchmark securities, prepayment/default projections based on historical data and other observable inputs.

Foreign Currency Derivative Contracts

Our foreign currency derivative contracts have maturities of 18 months or less and all are with counterparties that have a minimum credit rating of A- or equivalent by S&P Global Ratings, Moody’s Investors Service, Inc. or Fitch Ratings, Inc. We estimate the fair values of these contracts by utilizing an income-based industry standard valuation model for which all significant inputs are observable, either directly or indirectly. These inputs include foreign currency exchange rates, Secured Overnight Financing Rate (“SOFR”) and swap rates. These inputs, where applicable, are observable at commonly quoted intervals.

Senior Unsecured Notes

The following table summarizes the total estimated fair value and carrying value of our senior unsecured notes, determined using Level 2 inputs based on their quoted market values:

(in millions)June 30, 2024December 31, 2023
Fair value$19,841$22,567
Carrying value$22,091$23,834

Level 3 Inputs

Contingent Consideration Liability

In connection with our first quarter 2021 acquisition of MYR, we are subject to a potential contingent consideration payment of up to €300 million, subject to customary adjustments, which is revalued each reporting period using probability-weighted scenarios for U.S. Food and Drug Administration (“FDA”) approval of Hepcludex until the related contingency is resolved.

The following table summarizes the change in fair value of our contingent consideration liability:

(1) Included in Research and development expenses on our Condensed Consolidated Statements of Operations. The changes in 2024 and 2023 primarily related to changes in assumptions around probability and timing of regulatory approval.

(2) Included in Other (income) expense, net on our Condensed Consolidated Statements of Operations.

(3) Included in Other long-term obligations on our Condensed Consolidated Balance Sheets.

Liability Related to Future Royalties

We recorded a liability related to future royalties as part of our 2020 acquisition of Immunomedics, Inc. (“Immunomedics”), which is subsequently amortized using the effective interest method over the remaining estimated life. The fair value of the liability related to future royalties was approximately $1.1 billion and $1.2 billion as of June 30, 2024 and December 31, 2023, respectively, and the carrying value was $1.2 billion as of June 30, 2024 and December 31, 2023.

Liability Related to Assumed Financing Arrangement

As part of the CymaBay acquisition, we assumed a liability for a financing arrangement (see Note 6. Acquisitions, Collaborations and Other Arrangements). The fair value of the liability approximates its carrying value of $99 million as of June 30, 2024.

Nonrecurring Fair Value Measurements

During the six months ended June 30, 2024, we recorded a partial impairment charge of $2.4 billion related to certain acquired in-process research and development (“IPR&D”) assets. See Note 7. Intangible Assets for additional information.

Fair Value Level Transfers

There were no transfers between Level 1, Level 2 and Level 3 in the periods presented.

4. AVAILABLE-FOR-SALE DEBT SECURITIES AND EQUITY SECURITIES

Available-for-Sale Debt Securities

During the three months ended March 31, 2024, we sold all of our available-for-sale debt securities and used the proceeds to partially fund our acquisition of CymaBay discussed in Note 6.

5. DERIVATIVE FINANCIAL INSTRUMENTS

Our operations in foreign countries expose us to market risk associated with foreign currency exchange rate fluctuations between the U.S. dollar and various foreign currencies, primarily the Euro. To manage this risk, we hedge a portion of our foreign currency exposures related to outstanding monetary assets and liabilities as well as forecasted product sales using foreign currency exchange forward contracts. In general, the market risk related to these contracts is offset by corresponding gains and losses on the hedged transactions. The credit risk associated with these contracts is driven by changes in interest and currency exchange rates and, as a result, varies over time. By working only with major banks and closely monitoring current market conditions, we seek to limit the risk that counterparties to these contracts may be unable to perform. We also seek to limit our risk of loss by entering into contracts that permit net settlement at maturity. Therefore, our overall risk of loss in the event of a counterparty default is limited to the amount of any unrealized gains on outstanding contracts (i.e., those contracts that have a positive fair value) at the date of default. We do not enter into derivative contracts for trading purposes.

The derivative instruments we use to hedge our exposures for certain monetary assets and liabilities that are denominated in a non-functional currency are not designated as hedges. The derivative instruments we use to hedge our exposures for forecasted product sales are designated as cash flow hedges and have maturities of 18 months or less.

We held foreign currency exchange contracts with outstanding notional amounts of $2.5 billion as of June 30, 2024 and December 31, 2023.

While all our derivative contracts allow us the right to offset assets and liabilities, we have presented amounts in our Condensed Consolidated Balance Sheets on a gross basis. The following table summarizes the classification and fair values of derivative instruments, including the potential effect of offsetting:

The majority of gains and losses related to the hedged forecasted transactions reported in Accumulated other comprehensive income as of June 30, 2024 are expected to be reclassified to Product sales within 12 months. There were no discontinuances of cash flow hedges for the three and six months ended June 30, 2024 and 2023.

The cash flow effects of our derivative contracts for the six months ended June 30, 2024 and 2023 were included within Net cash provided by operating activities on our Condensed Consolidated Statements of Cash Flows.

6. ACQUISITIONS, COLLABORATIONS AND OTHER ARRANGEMENTS

We enter into acquisitions, licensing and strategic collaborations and other similar arrangements with third parties for the research, development and commercialization of certain products and product candidates. The collaborations involve two or more parties who are active participants in the operating activities of the collaboration and are exposed to significant risks and rewards depending on the commercial success of the activities. The financial terms of these arrangements may include non-refundable upfront payments, expense reimbursements or payments by us for options to acquire certain rights, contingent obligations by us for potential development and regulatory milestone payments and/or sales-based milestone payments, royalty payments, revenue or profit-sharing arrangements, cost-sharing arrangements and equity investments.

Acquisitions

CymaBay

In March 2024, we completed the acquisition of CymaBay Therapeutics, Inc. (“CymaBay”) for total consideration of $3.9 billion, net of cash acquired. Upon closing, CymaBay became our wholly-owned subsidiary. CymaBay’s lead program, seladelpar, is an investigational, oral, selective peroxisome proliferator-activated receptor delta agonist, shown to regulate critical metabolic and liver disease pathways. Based on data evaluating the efficacy and tolerability profile of seladelpar in more than 500 participants across Phase 2 and Phase 3 studies, a new drug application for seladelpar was submitted to FDA in December 2023.

We accounted for this transaction as an asset acquisition since the lead asset, seladelpar, represents substantially all of the fair value of the gross assets acquired. During the three months ended March 31, 2024, we recorded a $3.9 billion charge, representing an acquired IPR&D asset with no alternative future use, to Acquired in-process research and development expenses on our Condensed Consolidated Statements of Operations. In connection with this acquisition, we recorded $263 million of assets acquired, primarily consisting of deferred tax assets, and $228 million of liabilities assumed, primarily related to an assumed financing arrangement which would be repaid partially upon a change of control and partially upon an approval-based fixed milestone and future sales-based milestones related to seladelpar. The change of control payment of $101 million was made during the three months ended June 30, 2024. See Note 9. Debt and Credit Facilities for disclosure of the remaining liability related to the future milestone payments. During the three months ended March 31, 2024, we also recorded share-based compensation expense of $133 million related to the cash settlement of unvested CymaBay employee stock awards attributable to post-acquisition services, with $67 million being recorded in Research and development expenses and $67 million in Selling, general and administrative expenses on our Condensed Consolidated Statements of Operations.

In July 2024, we paid $320 million to Janssen Pharmaceutica NV to extinguish a future royalty obligation related to seladelpar, which will result in a charge to Acquired in-process research and development expenses on our Condensed Consolidated Statements of Operations for the three months ended September 30, 2024.

XinThera

In May 2023, we closed an agreement to acquire XinThera, Inc. (“XinThera”), a privately held biotechnology company focused on small molecule drugs to treat cancer and immunologic diseases, for approximately $200 million in cash consideration, net of cash acquired. As a result, XinThera became our wholly-owned subsidiary.

We accounted for the transaction as an asset acquisition and recorded a $170 million charge to Acquired in-process research and development expenses on our Condensed Consolidated Statements of Operations during the three months ended June 30, 2023. The remaining purchase price relates to various other assets acquired and liabilities assumed. Under the agreement, the former shareholders of XinThera are eligible to receive performance-based development and regulatory milestone payments of up to approximately $760 million, with the first $50 million of such milestones paid and charged primarily to Acquired in-process research and development expenses in October 2023.

Tmunity

In February 2023, we closed an agreement to acquire Tmunity Therapeutics, Inc. (“Tmunity”), a clinical-stage, private biotechnology company focused on next-generation chimeric antigen receptor (“CAR”) T-therapies and technologies. Under the terms of the agreement, we acquired all outstanding shares of Tmunity other than those already owned by Gilead for approximately $300 million in cash consideration. As a result, Tmunity became our wholly-owned subsidiary.

We accounted for the transaction as an asset acquisition and recorded a $244 million charge to Acquired in-process research and development expenses on our Condensed Consolidated Statements of Operations during the three months ended March 31, 2023. The remaining purchase price relates to various other assets acquired and liabilities assumed, consisting primarily of deferred tax assets. Under the agreement, the former shareholders of Tmunity and the University of Pennsylvania are eligible to receive a mix of up to approximately $1.0 billion in potential future payments upon achievement of certain development, regulatory and sales-based milestones, as well as royalty payments on sales, with the first $25 million of milestones charged to Acquired in-process research and development expenses in 2023 and paid in January 2024.

Collaborations and Other Arrangements

Arcus

In January 2024, we amended our collaboration agreement with Arcus whereby we acquired approximately 15.2 million additional shares of Arcus common stock at a premium for $320 million, increasing our ownership to 30.1 million shares, or 33% of the issued and outstanding voting stock of Arcus immediately following the closing of the transaction. We recorded $233 million for the fair value of the equity investment in Prepaid and other current assets on our Condensed Consolidated Balance Sheets and $87 million for the premium in Other (income) expense, net on our Condensed Consolidated Statements of Operations. We also recorded a charge for the $100 million fourth anniversary option continuation fee under the amended agreement to Acquired in-process research and development expenses on our Condensed Consolidated Statements of Operations, which is accrued as of June 30, 2024 with payment expected to be made in the third quarter of 2024. At that time, the payment will be included within Net cash used in investing activities on our Condensed Consolidated Statements of Cash Flows. Our number of designees on Arcus’ board of directors was also increased to three.

(1) The Indefinite-lived assets – IPR&D balance as of December 31, 2023 was comprised of $5.9 billion related to sacituzumab govitecan-hziy (“SG”) for non-small cell lung cancer (“NSCLC”) and $1.1 billion related to bulevirtide. See “2024 IPR&D Impairment” below for 2024 activity.

Impairment Assessments

No intangible asset-related indicators of impairment were noted for the three and six months ended June 30, 2024 and 2023, except as described under “2024 IPR&D Impairment” below.

2024 IPR&D Impairment

In January 2024, we received data from our Phase 3 EVOKE-01 study of Trodelvy evaluating SG indicating that the study did not meet its primary endpoint of overall survival in previously treated metastatic NSCLC, thus triggering a review for potential impairment of the NSCLC IPR&D intangible asset.

Based on our evaluation of the study results and all other data currently available, and in connection with the preparation of the financial statements for the first quarter, we performed an interim impairment test and determined that the revised estimated fair value of the NSCLC IPR&D intangible asset was below its carrying value. As a result, we recognized a partial impairment charge of $2.4 billion in In-process research and development impairment on our Condensed Consolidated Statements of Operations for the three months ended March 31, 2024.

To arrive at the revised estimated fair value, we used a probability-weighted income approach that discounts expected future cash flows to present value, which requires the use of Level 3 fair value measurements and inputs, and requires the use of critical estimated inputs, including: revenues and operating profits related to the planned utilization of SG in NSCLC, which includes inputs such as addressable patient population, projected market share, treatment duration, and the life of the potential commercialized product; the probability of technical and regulatory success; the time and resources needed to complete the development and approval of SG in NSCLC; an appropriate discount rate based on the estimated weighted-average cost of capital for companies with profiles similar to our profile; and risks related to the viability of and potential alternative treatments in any future target markets. We used a discount rate of 7.00% which is based on the estimated weighted-average cost of capital for companies with profiles similar to ours. The revised estimated fair value of the NSCLC IPR&D intangible asset was $3.5 billion as of March 31, 2024.

Senior Unsecured Notes

In April 2024, we repaid at maturity $1.75 billion of principal balance related to our senior unsecured notes. We are required to comply with certain covenants under our note indentures governing our senior unsecured notes. As of June 30, 2024, we were not in violation of any covenants.

Credit Facilities

In June 2024, we terminated our $2.5 billion revolving credit facility maturing in June 2025 (the “2020 Revolving Credit Facility”) and entered into a new $2.5 billion revolving credit facility maturing in June 2029 (the “2024 Revolving Credit Facility”), which has terms substantially similar to the 2020 Revolving Credit Facility. The 2024 Revolving Credit Facility can be used for working capital requirements and for general corporate purposes, including, without limitation, acquisitions. As of June 30, 2024 and December 31, 2023, there were no amounts outstanding under these revolving credit facilities.

The 2024 Revolving Credit Facility contains customary representations, warranties, affirmative and negative covenants and events of default. At June 30, 2024, we were in compliance with all covenants. Loans under the 2024 Revolving Credit Facility bear interest at either (i) Term SOFR plus the Applicable Percentage, (ii) the Alternative Currency Term Rate plus the Applicable Percentage, or (iii) the Base Rate plus the Applicable Percentage, each as defined in the 2024 Revolving Credit Facility agreement. We may terminate or reduce the commitments and may prepay any loans under the 2024 Revolving Credit Facility in whole or in part at any time without premium or penalty.

10. COMMITMENTS AND CONTINGENCIES

Legal Proceedings

We are a party to various legal actions. Certain significant matters are described below. We recognize accruals for such actions to the extent that we conclude that a loss is both probable and reasonably estimable. We accrue for the best estimate of a loss within a range; however, if no estimate in the range is better than any other, then we accrue the minimum amount in the range. If we determine that a material loss is reasonably possible and the loss or range of loss can be estimated, we disclose the possible loss. Unless otherwise noted, the outcome of these matters either is not expected to be material or is not possible to determine such that we cannot reasonably estimate the maximum potential exposure or the range of possible loss. We did not have any material accruals for the matters described herein on our Condensed Consolidated Balance Sheets as of June 30, 2024 and December 31, 2023.

Litigation Relating to Pre-Exposure Prophylaxis

In August 2019, we filed petitions requesting inter partes review of U.S. Patent Nos. 9,044,509, 9,579,333, 9,937,191 and 10,335,423 (collectively, “HHS Patents”) by the Patent Trial and Appeal Board (“PTAB”). The HHS Patents are assigned to the U.S. Department of Health and Human Services (“HHS”) and purport to claim a process of protecting a primate host from infection by an immunodeficiency retrovirus by administering a combination of FTC and tenofovir disoproxil fumarate (“TDF”) or TAF prior to exposure of the host to the immunodeficiency retrovirus, a process commonly known as pre-exposure prophylaxis (“PrEP”). In November 2019, the U.S. Department of Justice filed a lawsuit against us in the U.S. District Court of Delaware, alleging that the sale of Truvada and Descovy for use as PrEP infringes the HHS Patents. In February 2020, PTAB declined to institute our petitions for inter partes review of the HHS Patents. In April 2020, we filed a lawsuit against the U.S. federal government in the U.S. Court of Federal Claims (“CFC”), alleging breach of three material transfer agreements (“MTAs”) related to the research underlying the HHS Patents and two clinical trial agreements (“CTAs”) by the U.S. Centers for Disease Control and Prevention related to PrEP research. A trial for the bifurcated portion of the lawsuit in the CFC was held in June 2022, and in November 2022, the CFC determined that the government breached the MTAs. In January 2024, the CFC found the government liable for breach of both CTAs. A separate trial at the CFC to determine the damages we are owed based on the government’s breaches has been scheduled for December 2024. In May 2023, the District Court held a trial regarding the government’s patent infringement claims, and the jury rendered a full defense verdict in favor of Gilead, finding that the asserted claims of the HHS Patents are invalid and the HHS patents are not infringed. In March 2024, the District Court upheld the jury’s verdict that the government’s patents are invalid, denied the government’s request for a new trial and then entered final judgment. In July 2024, the government filed a notice of appeal. Although we cannot predict with certainty the ultimate outcome of each of these litigation matters, we believe that the U.S. federal government breached its contracts with Gilead, that Truvada and Descovy do not infringe the HHS Patents and that the HHS Patents are invalid over prior art descriptions of Truvada’s use for PrEP and post-exposure prophylaxis because physicians and patients were using the claimed methods years before HHS filed the applications for the patents.

Litigation with Generic Manufacturers

As part of the approval process for some of our products, FDA granted us a New Chemical Entity (“NCE”) exclusivity period during which other manufacturers’ applications for approval of generic versions of our products will not be approved. Generic manufacturers may challenge the patents protecting products that have been granted NCE exclusivity one year prior to the end of the NCE exclusivity period. Generic manufacturers have sought and may continue to seek FDA approval for a similar or identical drug through an abbreviated new drug application (“ANDA”), the application form typically used by manufacturers seeking approval of a generic drug. The sale of generic versions of our products prior to their patent expiration would have a significant negative effect on our revenues and results of operations. To seek approval for a generic version of a product having NCE status, a generic company may submit its ANDA to FDA four years after the branded product’s approval.

In October 2021, we received a letter from Lupin Ltd. (“Lupin”) indicating that it has submitted an ANDA to FDA requesting permission to market and manufacture a generic version of Symtuza, a product commercialized by Janssen and for which Gilead shares in revenues. In November 2021, we, along with Janssen and Janssen Products, L.P., filed a patent infringement lawsuit against Lupin as co-plaintiffs in the U.S. District Court of Delaware. In September 2022, we received a letter from Apotex Inc. and Apotex Corp. (“Apotex”) stating that they have submitted an ANDA for a generic version of Symtuza. In October 2022, we, along with Janssen and Janssen Products, L.P., filed a patent infringement lawsuit against Apotex as co-plaintiffs in the U.S. District Court of Delaware. The cases against Lupin and Apotex have been consolidated into a single trial scheduled for February 2025.

Starting in March 2022, we received letters from Lupin, Laurus Labs (“Laurus”) and Cipla Ltd. (“Cipla”), indicating that they have submitted ANDAs to FDA requesting permission to market and manufacture generic versions of the adult dosage strength of Biktarvy. Lupin, Laurus, and Cipla have challenged the validity of four of the six patents listed in the Orange Book as associated with Biktarvy. We filed a lawsuit against Lupin, Laurus and Cipla in May 2022 in the U.S. District Court of Delaware, and intend to enforce and defend our intellectual property. Additionally, in November 2023, we received a letter from Cipla indicating that it has submitted an ANDA to FDA requesting permission to market and manufacture a generic version of the pediatric dosage strength of Biktarvy. Cipla challenged the validity of two of the patents listed in the Orange Book as associated with Biktarvy. We filed a separate lawsuit against Cipla in December 2023 in the U.S. District Court of Delaware. This lawsuit has been consolidated with the first lawsuit, with a single trial scheduled for October 2025.

In June 2023, we received a letter from Apotex indicating that it has submitted an ANDA to FDA requesting permission to market and manufacture a generic version of Genvoya. In July 2023, we filed a patent infringement lawsuit against Apotex in the U.S. District Court of Delaware, and intend to enforce and defend our intellectual property. This case has been consolidated with the Symtuza matters discussed above, and a trial has been scheduled for February 2025.

Antitrust and Consumer Protection

We, along with Bristol-Myers Squibb Company (“BMS”), Johnson & Johnson, Inc. (“Johnson & Johnson”), and Teva Pharmaceutical Industries Ltd. (“Teva”) have been named as defendants in class action lawsuits filed in 2019 and 2020 related to various drugs used to treat HIV, including drugs used in combination antiretroviral therapy. Plaintiffs allege that we (and the other defendants) engaged in various conduct to restrain competition in violation of federal and state antitrust laws and state consumer protection laws. The lawsuits, which have been consolidated, are pending in the U.S. District Court for the Northern District of California. The lawsuits seek to bring claims on behalf of direct purchasers consisting largely of wholesalers and indirect or end-payor purchasers, including health insurers and individual patients. Plaintiffs seek damages, permanent injunctive relief and other relief. In the second half of 2021 and first half of 2022, several plaintiffs consisting of retail pharmacies, individual health plans and United Healthcare, filed separate lawsuits effectively opting out of the class action cases, asserting claims that are substantively the same as the classes. These cases have been coordinated with the class actions. In March 2023, the District Court granted our motion to hold separate trials as to (i) the allegations against us and Teva seeking monetary damages relating to Truvada and Atripla (“Phase I”) and (ii) the allegations against us and, in part, Johnson & Johnson, seeking monetary damages and injunctive relief relating to Complera (“Phase II”). In May 2023, we settled claims with the direct purchaser class and the retailer opt-out plaintiffs for $525 million, which we paid in the second half of 2023. The settlement agreements are not an admission of liability or fault by us. In June 2023, the jury returned a complete verdict in Gilead’s favor on the remaining plaintiffs’ Phase I allegations. In November 2023, the court denied plaintiffs’ motion to set aside the verdict, and in February 2024, the court entered final judgment on the Phase I verdict and certain summary judgment rulings. In March 2024, plaintiffs filed notices of appeal of the Phase I verdict and those summary judgment rulings as to which the court entered final judgment. The court has stayed Phase II pending the appeal of Phase I. While we intend to vigorously oppose the appeal and defend against the Phase II claims, we cannot predict the ultimate outcome. If plaintiffs are successful in their appeal or Phase II claims, we could be required to pay monetary damages or could be subject to permanent injunctive relief in favor of plaintiffs.

In January 2022, we, along with BMS and Janssen Products, L.P., were named as defendants in a lawsuit filed in the Superior Court of the State of California, County of San Mateo, by Aetna, Inc. on behalf of itself and its affiliates and subsidiaries that effectively opts the Aetna plaintiffs out of the above class actions. The allegations are substantively the same as those in the class actions. The Aetna plaintiffs seek damages, permanent injunctive relief and other relief. In March 2024, the court denied our motion for judgment on the pleadings to preclude Aetna from re-litigating claims that were dismissed at summary judgment in the above class action cases. We filed a writ petition appealing the denial of our motion for judgment on the pleadings, which the appellate court denied in May 2024. In April 2024, the court granted our motion to bifurcate the case to adjudicate the issue of preclusion before litigating the merits of the case. In July 2024, Aetna filed a request to voluntarily dismiss two of its claims with prejudice, which the court subsequently granted, leaving only the claims related to Truvada and Atripla.

In February 2021, we, along with BMS and Teva, were named as defendants in a lawsuit filed in the First Judicial District Court for the State of New Mexico, County of Santa Fe by the New Mexico Attorney General. The New Mexico Attorney General alleges that we (and the other defendants) restrained competition in violation of New Mexico antitrust and consumer protection laws. The New Mexico Attorney General seeks damages, permanent injunctive relief and other relief. We moved to dismiss the case based on lack of personal jurisdiction and, in July 2023, the New Mexico Supreme Court remanded the case back to the trial court for limited jurisdictional discovery.

We intend to vigorously defend ourselves in these actions, however, we cannot predict the ultimate outcome. If plaintiffs are successful in their claims, we could be required to pay significant monetary damages or could be subject to permanent injunctive relief awarded in favor of plaintiffs, which may result in a material, adverse effect on our results of operations and financial condition, including in a particular reporting period in which any such outcome becomes probable and estimable.

Product Liability

We have been named as a defendant in one putative class action lawsuit and various product liability lawsuits related to Viread, Truvada, Atripla, Complera and Stribild. Plaintiffs allege that Viread, Truvada, Atripla, Complera and/or Stribild caused them to experience kidney, bone and/or tooth injuries. The lawsuits, which are pending in state or federal court in California and Missouri, involve approximately 25,000 active plaintiffs. Plaintiffs in these cases seek damages and other relief on various grounds for alleged personal injury and economic loss. The first bellwether trial in California state court was scheduled to begin in October 2022, but is currently stayed pending the conclusion of appellate proceedings in the California Supreme Court. A bellwether trial date in California federal court has been vacated following a settlement agreement in principle. Specifically, Gilead reached an agreement to make a one-time payment of up to $40 million to a group of eligible plaintiffs (approximately 2,625 plaintiffs). The agreement is subject to certain conditions, including that at least 98% of eligible plaintiffs elect to participate in the settlement. The putative class action in Missouri is currently awaiting decision from the court whether to certify the proposed class. We intend to vigorously defend ourselves in these actions, however, we cannot predict the ultimate outcome. If plaintiffs are successful in their claims, we could be required to pay significant monetary damages, which may result in a material, adverse effect on our results of operations and financial condition, including in a particular reporting period in which any such outcome becomes probable and estimable.

Government Investigation

In 2017, we received a subpoena from the U.S. Attorney’s Office for the Southern District of New York requesting documents related to our promotional speaker programs for HIV. We are cooperating with this inquiry.

Qui Tam Litigation

A former sales employee filed a qui tam lawsuit against Gilead in March 2017 in U.S. District Court for the Eastern District of Pennsylvania. Following the government’s decision not to intervene in the suit, the case was unsealed in December 2020. The lawsuit alleges that certain of Gilead’s HCV sales and marketing activities violated the federal False Claims Act and various state false claims acts. The lawsuit seeks all available relief under these statutes.

Health Choice Advocates, LLC (“Health Choice”) filed a qui tam lawsuit against Gilead in May 2020 in Texas state court. The lawsuit alleged that Gilead violated the Texas Medicare Fraud Prevention Act (“TMFPA”) through our clinical educator programs for Sovaldi and Harvoni and our HCV and HIV patient support programs. The lawsuit sought all available relief under the TMFPA. Health Choice voluntarily dismissed the case without prejudice in August 2023, and commenced a new action in October 2023, asserting largely identical allegations and claims. In the newly filed action, the Texas Attorney General has intervened as a plaintiff.

We intend to vigorously defend ourselves in these actions, however, we cannot predict the ultimate outcomes. If any of these plaintiffs are successful in their claims, we could be required to pay significant monetary damages, which may result in a material, adverse effect on our results of operations and financial condition, including in a particular reporting period in which any such outcome becomes probable and estimable.

Other Matters

We are a party to various legal actions that arose in the ordinary course of our business. We do not believe that it is probable or reasonably possible that these other legal actions will have a material adverse impact on our consolidated financial position, results of operations or cash flows.

11. EARNINGS (LOSS) PER SHARE

The following table shows the calculation of Basic and Diluted earnings (loss) per share attributable to Gilead:

Three Months EndedSix Months Ended
June 30,June 30,
(in millions, except per share amounts)2024202320242023
Net income (loss) attributable to Gilead$1,614$1,045$(2,556)$2,055
Shares used in basic earnings (loss) per share attributable to Gilead calculation1,2471,2491,2471,249
Dilutive effect of stock options and equivalents49—11
Shares used in diluted earnings (loss) per share attributable to Gilead calculation1,2511,2581,2471,260
Basic earnings (loss) per share attributable to Gilead$1.29$0.84$(2.05)$1.65
Diluted earnings (loss) per share attributable to Gilead$1.29$0.83$(2.05)$1.63

Potential shares of common stock excluded from the computation of Diluted earnings (loss) per share attributable to Gilead because their effect would have been antidilutive were 22 million and 19 million for the three and six months ended June 30, 2024, respectively, and 5 million and 3 million for the three and six months ended June 30, 2023, respectively.

12. INCOME TAXES

The following table summarizes our Income tax expense:

Three Months EndedSix Months Ended
June 30,June 30,
(in millions, except percentages)2024202320242023
Income (loss) before income taxes$2,053$1,588$(2,433)$2,888
Income tax expense$438$549$123$865
Effective tax rate21.4%34.6%(5.1)%29.9%

Our effective income tax rate of 21.4% for the three months ended June 30, 2024 differed from the U.S. federal statutory rate of 21% primarily due to unfavorable changes in the fair value of our equity investments that are non-deductible for income tax purposes, partially offset by a settlement with a tax authority.

Our effective income tax rate of (5.1)% for the six months ended June 30, 2024 differed from the U.S. federal statutory rate of 21% primarily due to $3.9 billion of non-deductible acquired IPR&D expense recorded in connection with our acquisition of CymaBay, partially offset by a decrease in state deferred tax liabilities associated with the $2.4 billion NSCLC IPR&D intangible asset impairment charge and settlements with tax authorities.

Our effective income tax rate of 34.6% and 29.9% for the three and six months ended June 30, 2023, respectively, differed from the U.S. federal statutory rate of 21% primarily due to remeasurement of certain deferred tax liabilities related to acquired intangible assets and non-deductible acquired IPR&D expenses recorded in connection with our second quarter 2023 acquisition of XinThera and first quarter 2023 acquisition of Tmunity.

Our income tax returns are subject to audit by federal, state and foreign tax authorities. We are currently under examination by the Internal Revenue Service for our 2019 to 2021 tax years. There are differing interpretations of tax laws and regulations, and as a result, significant disputes may arise with these tax authorities involving issues on the timing and amount of deductions and allocations of income among various tax jurisdictions. We periodically evaluate our exposures associated with our tax filing positions.
