[10-Q] Exelixis Inc Quarterly Earnings Report

Rhea-AI Filing Summary

Exelixis (EXEL) posted mixed Q2 2025 results. Net product revenue rose 19% YoY to $520.0 m on continued CABOMETYX growth, lifting six-month product sales 27% to $1.03 b. However, the absence of last year’s $150 m Ipsen milestone drove collaboration revenue down 76% to $48.3 m, pulling total quarterly revenue to $568.3 m (-11%). Operating expenses were flat; yet operating income fell 23% to $213.6 m and net income slid 18% to $184.8 m, or $0.65 diluted EPS (vs $0.77).

Year-to-date momentum remains solid. For the first six months, revenue climbed 6% to $1.12 b and net income jumped 31% to $344.5 m ($1.20 EPS) thanks to stronger U.S. product demand and lower restructuring charges. Operating cash flow improved 38% to $260.4 m.

Capital allocation and balance sheet. The company repurchased 21.7 m shares for $796 m, trimming cash and investments to $1.38 b (-21% YTD) and reducing shares outstanding to 270.1 m. Equity compensation expense was $62 m (+39%).

Pipeline & legal. EXEL settled with Biocon, deferring U.S. generic entry until 1 Jan 2031. ANDA challenges from MSN, Sun and Azurity continue; recent Delaware rulings upheld key patents through 2030, but appeals are pending. R&D spend fell 5% to $200.4 m as the phase 3 zanzalintinib program advances.

Insights

Sell-side Biopharma Analyst

TL;DR: Solid drug sales offset by milestone lap; 2031 Biocon deal preserves franchise.

Core CABOMETYX demand remains robust, evidenced by 23% gross sales growth and negligible price erosion. The Ipsen milestone comp hurt optics, but excluding that one-off, revenue grew high-teens and operating leverage was respectable. Share buybacks are accretive, cutting diluted share count 3%, but cash draw is meaningful (cash & M-secs now ~50% of market cap). Importantly, the Biocon settlement pushes first authorized generic to 2031, extending cash flows beyond earlier bear cases. Litigation with MSN and Sun still presents headline risk; nevertheless, the January 2030 court protection plus potential FDA exclusivity provide a multi-year runway. Valuation hinges on next-gen asset zanzalintinib; R&D cadence suggests data inflection 2026. Overall tone: neutral-positive.

Risk Analyst

TL;DR: Litigation overhang persists; liquidity remains ample despite heavy buybacks.

Exelixis burned >$600 m on repurchases in six months, yet retains $1.4 b of highly liquid securities and zero debt, limiting near-term solvency concerns. Patent defenses have held in Delaware, but CAFC outcomes are binary; an adverse ruling could accelerate generic entry by up to a year, eroding 2029-30 cash flows. Concentration risk is evident: five U.S. specialty distributors account for 77% of revenue, and cabozantinib drives >90% of sales. Management’s discipline in reinvesting vs returning capital will be critical as pipeline assets mature. Overall impact: moderately positive but watch legal milestones.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(unaudited)

NOTE 1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Organization

Exelixis, Inc. (Exelixis, we, our or us) is an oncology company innovating next-generation medicines and combination regimens at the forefront of cancer care. We have produced four marketed pharmaceutical products, two of which are formulations of our flagship molecule, cabozantinib, and we are steadily advancing and evolving our product pipeline portfolio, including our lead asset zanzalintinib, currently the focus of an extensive phase 3 clinical development program. With a rational and disciplined approach to investment, we are leveraging our internal experience and expertise, and the strength of strategic partnerships, to identify and pursue opportunities across the landscape of scientific modalities, including small molecules, biotherapeutics and antibody-drug conjugates.

Sales related to cabozantinib account for the majority of our revenues. Cabozantinib is an inhibitor of multiple tyrosine kinases, including MET, AXL, VEGF receptors and RET and has been approved by the U.S. Food and Drug Administration (FDA) and in other countries as CABOMETYX® (cabozantinib) tablets for: advanced renal cell carcinoma (both alone and in combination with Bristol-Myers Squibb Company’s nivolumab (OPDIVO®)), previously treated hepatocellular carcinoma, previously treated, radioactive iodine-refractory differentiated thyroid cancer, and previously treated, unresectable, locally advanced or metastatic, well-differentiated pancreatic neuroendocrine tumors and extra-pancreatic neuroendocrine tumors; and as COMETRIQ® (cabozantinib) capsules for progressive, metastatic medullary thyroid cancer. For physicians treating these types of cancer, cabozantinib has become or is becoming an important medicine in their selection of effective therapies.

The other two products resulting from our discovery efforts are: COTELLIC® (cobimetinib), an inhibitor of MEK approved as part of multiple combination regimens to treat specific forms of advanced melanoma and marketed under a collaboration with Genentech, Inc. (a member of the Roche Group) (Genentech); and MINNEBRO® (esaxerenone), an oral, non-steroidal, selective blocker of the mineralocorticoid receptor, approved for the treatment of hypertension in Japan and licensed to Daiichi Sankyo Company, Limited.

Basis of Presentation

The accompanying unaudited Condensed Consolidated Financial Statements include the accounts of Exelixis and those of our wholly owned subsidiaries. These entities’ functional currency is the U.S. dollar. All intercompany balances and transactions have been eliminated.

We have adopted a 52- or 53-week fiscal year policy that generally ends on the Friday closest to December 31. Fiscal year 2025, which is a 52-week fiscal year, will end on January 2, 2026 and fiscal year 2024, which was a 53-week fiscal year, ended on January 3, 2025. For convenience, references in this report as of and for the fiscal periods ended July 4, 2025 and June 28, 2024, and as of and for the fiscal years ending January 2, 2026 and ended January 3, 2025, are indicated as being as of and for the periods ended June 30, 2025 and June 30, 2024, and the years ending December 31, 2025 and ended December 31, 2024, respectively.

The accompanying Condensed Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the U.S. for interim financial information and pursuant to Form 10-Q and Article 10 of Regulation S-X of the Securities and Exchange Commission (SEC). Accordingly, they do not include all of the information and footnotes required by U.S. generally accepted accounting principles for complete financial statements. In our opinion, all adjustments (consisting only of normal recurring adjustments) considered necessary for a fair presentation of our financial statements for the periods presented have been included. Operating results for the six months ended June 30, 2025 are not necessarily indicative of the results that may be expected for the year ending December 31, 2025 or for any future period. The accompanying Condensed Consolidated Financial Statements and Notes thereto should be read in conjunction with our Consolidated Financial Statements and Notes thereto for the fiscal year ended December 31, 2024, included in Part II, Item 8 of our Annual Report on Form 10-K, filed with the SEC on February 11, 2025 (Fiscal 2024 Form 10-K).

Use of Estimates

The preparation of the accompanying Condensed Consolidated Financial Statements conforms to accounting principles generally accepted in the U.S., which requires management to make judgments, estimates and assumptions that affect the reported amounts of assets, liabilities, equity, revenues and expenses and related disclosures. On an ongoing basis, we evaluate our significant estimates. We base our estimates on historical experience and on various other market-specific and other relevant assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results could differ materially from those estimates.

Reclassifications

Certain prior period amounts in the accompanying Condensed Consolidated Financial Statements have been reclassified to conform to the current period presentation. Such reclassifications did not impact previously reported total revenues, income from operations, net income, total assets, total liabilities or total stockholders’ equity.

Significant Accounting Policies

There have been no material changes to our significant accounting policies during the six months ended June 30, 2025, as compared to the significant accounting policies disclosed in “Note 1. Organization and Summary of Significant Accounting Policies” of the “Notes to Consolidated Financial Statements” included in Part II, Item 8 of our Fiscal 2024 Form 10-K.

Recently Adopted Accounting Pronouncements

There were no new accounting pronouncements adopted by us since our filing of the Fiscal 2024 Form 10-K, which could have a significant effect on our Condensed Consolidated Financial Statements.

Recent Accounting Pronouncements Not Yet Adopted

In December 2023, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (ASU 2023-09), which enhances the disclosures required for income taxes in our annual consolidated financial statements. ASU 2023-09 is effective for us in our annual reporting for fiscal 2025 on a prospective basis. Early adoption and retrospective reporting are permitted. We are currently evaluating the impact of ASU 2023-09 on our Consolidated Financial Statements.

In November 2024, the FASB issued ASU 2024-03, Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses (ASU 2024-03), which enhances the disclosures required for expense disaggregation in our annual and interim consolidated financial statements. In January 2025, the FASB issued ASU 2025-01, Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures (Subtopic 220-40) – Clarifying the effective Date (ASU 2025-01), which clarifies the effective date of ASU 2024-03 for companies with a non-calendar year end. ASU 2024-03 is effective for us in our annual reporting for fiscal year 2027, and in our interim periods beginning in fiscal year 2028. Early adoption and retrospective application are permitted. We are currently evaluating the impact of ASU 2024-03 on our Consolidated Financial Statements.

NOTE 2. SEGMENT REPORTING

We operate in one business segment that focuses on the discovery, development and commercialization of new medicines for difficult-to-treat cancers. Our President and Chief Executive Officer, as the chief operating decision-maker, manages and allocates resources to our operations on a total consolidated basis. Consistent with this decision-making process, our President and Chief Executive Officer uses net income to monitor budget versus actual results for purposes of evaluating performance and to make decisions about the allocation of resources.

Our significant segment expenses that are regularly provided to our President and Chief Executive Officer and included in the measure of segment net income consist of consolidated expenses for our operational departments: drug discovery, development, and selling, general and administrative and other segment items.

The allowance for chargebacks, discounts for prompt payment and other are recorded as a reduction of trade receivables, net, and the remaining reserves are recorded as rebates and fees due to customers in the accompanying Condensed Consolidated Balance Sheets.

Contract Assets and Liabilities

We receive payments from our collaboration partners based on billing schedules established in each contract. Amounts are recorded as accounts receivable when our right to consideration is unconditional. We may also recognize revenue in advance of the contractual billing schedule and such amounts are recorded as a contract asset when recognized. We may be required to defer recognition of revenue for upfront and milestone payments until we perform our obligations under these arrangements, and such amounts are recorded as deferred revenue upon receipt or when due. For those contracts that have multiple performance obligations, contract assets and liabilities are reported on a net basis at the contract level. Contract assets are primarily related to Ipsen Pharma SAS (Ipsen) and contract liabilities are primarily related to deferred revenues from Takeda Pharmaceutical Company Limited (Takeda).

Contract assets and liabilities were as follows (in thousands):

recognition of license revenues for the achievement of a commercial milestone payment and royalty payments allocated to our license performance obligations for our collaborations with Ipsen and Takeda.

As of June 30, 2025, $33.8 million of the combined transaction prices for our Ipsen and Takeda collaborations were allocated to research and development services performance obligations that had not yet been satisfied. See “Note 4. Collaboration Agreements and Business Development Activities” of the “Notes to Consolidated Financial Statements” included in Part II, Item 8 of our Fiscal 2024 Form 10-K for additional information about the expected timing to satisfy these performance obligations.

NOTE 4. COLLABORATION AGREEMENTS AND BUSINESS DEVELOPMENT ACTIVITIES

We have established multiple collaborations with leading biopharmaceutical companies for the commercialization and further development of our cabozantinib franchise. Additionally, we have made considerable progress under our existing research collaboration and in-licensing arrangements to further enhance our early-stage pipeline and expand our ability to discover, develop and commercialize novel therapies with the goal of providing new treatment options for cancer patients. Historically, we also entered into other collaborations with leading biopharmaceutical companies pursuant to which we out-licensed other compounds and programs in our portfolio.

See “Note 4. Collaboration Agreements and Business Development Activities” of the “Notes to Consolidated Financial Statements” included in Part II, Item 8 of our Fiscal 2024 Form 10-K, as further described below, for additional information on certain of our collaboration agreements and in-licensing arrangements.

Cabozantinib Commercial Collaborations

Ipsen Collaboration

In February 2016, we entered into a collaboration and license agreement with Ipsen, which was subsequently amended, for the commercialization and further development of cabozantinib. Under the collaboration agreement, as amended, Ipsen received exclusive commercialization rights for current and potential future cabozantinib indications outside of the U.S. and Japan. We have also agreed to collaborate with Ipsen on the development of cabozantinib for current and potential future indications. The parties’ efforts are governed through a joint steering committee and appropriate subcommittees established to guide and oversee the collaboration’s operation and strategic direction; provided, however, that we retain final decision-making authority with respect to cabozantinib’s ongoing development.

Revenues under the collaboration agreement with Ipsen were as follows (in thousands):

			Three Months Ended June 30,												Six Months Ended June 30,
			2025						2024						2025						2024
License revenues			$	39,540					$	187,926					$	73,519					$	224,787
Collaboration services revenues			(2,507)						2,633						(3,780)						1,475
Total collaboration revenues			$	37,033					$	190,559					$	69,739					$	226,262

During the three and six months ended June 30, 2024, we recognized $150.0 million in license revenues related to a commercial milestone payment from Ipsen upon its achievement of $600.0 million in cumulative net sales of cabozantinib over four consecutive quarters in its related Ipsen license territory.

Takeda Collaboration

In January 2017, we entered into a collaboration and license agreement with Takeda, which was subsequently amended, for the commercialization and further development of cabozantinib. Under the collaboration agreement, as amended, Takeda received exclusive commercialization rights for current and potential future cabozantinib indications in Japan, and the parties have agreed to collaborate on the clinical development of cabozantinib in Japan. The operation and strategic direction of the parties’ collaboration is governed through a joint executive committee and appropriate subcommittees.

Total collaboration revenues			$	5,286					$	5,272					$	9,002					$	11,167

Royalty Pharma

In October 2002, we established a product development and commercialization collaboration agreement with GlaxoSmithKline (now GSK plc, or GSK), that required us to pay a 3% royalty to GSK on the worldwide net sales of any product containing cabozantinib sold by us and our collaboration partners. Effective January 1, 2021, Royalty Pharma plc (Royalty Pharma) acquired from GSK all rights, title and interest in royalties on net product sales containing cabozantinib for non-U.S. markets for the full term of the royalty and for the U.S. market through September 2026, after which time U.S. royalties will revert back to GSK. Royalty fees earned by Royalty Pharma in connection with our sales of cabozantinib are included in cost of goods sold and as a reduction of collaboration services revenues for sales by our collaboration partners. Such royalty fees earned by Royalty Pharma were $21.4 million and $41.7 million during the three and six months ended June 30, 2025, respectively, as compared to $18.4 million and $35.1 million, respectively, for the corresponding prior year periods.

Research Collaborations, In-Licensing Arrangements and Other Business Development Activities

We enter into collaborative arrangements with other pharmaceutical or biotechnology companies to develop and commercialize oncology assets or other intellectual property. Our research collaborations and in-licensing arrangements are intended to enhance our early-stage pipeline and expand our ability to discover, develop and commercialize novel therapies with the goal of providing new treatment options for cancer patients. Our research collaborations, in-licensing arrangements and other strategic transactions generally include upfront payments for the purchase or in-licensing of intellectual property, development, regulatory and commercial milestone payments and royalty payments, in each case contingent upon the occurrence of certain future events linked to the success of the asset in development. Certain of our research collaborations provide us exclusive options that give us the right to license programs or acquire the intellectual property developed under the research collaborations for further discovery and development. When we decide to exercise the options, we are required to pay an exercise fee and then assume the responsibilities for all subsequent development, manufacturing and commercialization.

During the three and six months ended June 30, 2025, we recognized $5.7 million and $10.9 million, respectively, as compared to $5.8 million and $28.6 million, respectively, for the corresponding prior year periods, within research and development expenses on the Condensed Consolidated Statements of Income, primarily related to development milestone payments and option exercise fees for the cost of intellectual property that have not yet achieved technological feasibility, research and development funding and other fees.

As of June 30, 2025, in conjunction with the active collaborative in-licensing arrangements and asset purchase agreements, we are subject to potential future development milestone payments of up to $441.5 million, regulatory milestone payments of up to $278.0 million and commercial milestone payments of up to $2.4 billion, each in the aggregate per product or target, as well as royalties on future net sales of products.

There were 168 and 255 debt securities available-for-sale in an unrealized loss position as of June 30, 2025 and December 31, 2024, respectively. During the three and six months ended June 30, 2025, we did not record an allowance for credit losses or other impairment charges on our marketable securities. Based upon our quarterly impairment review, we determined that the unrealized losses were not attributed to credit risk but were primarily associated with changes in interest rates and market liquidity. Based on the scheduled maturities of our marketable securities, we determined that it was more likely than not that we will hold these marketable securities for a period of time sufficient for a recovery of our cost basis.

The fair values of debt securities available-for-sale by contractual maturity were as follows (in thousands):

			June 30, 2025						December 31, 2024
Maturing in one year or less			$	673,976					$	888,360

Total debt securities available-for-sale			$	1,268,628					$	1,525,651

NOTE 6. FAIR VALUE MEASUREMENTS

Fair value reflects the amounts that would be received upon sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value hierarchy has the following three levels:

•Level 1 - quoted prices (unadjusted) in active markets for identical assets and liabilities;

•Level 2 - inputs other than Level 1 that are observable either directly or indirectly, such as quoted prices in active markets for similar instruments or on industry models using data inputs, such as interest rates and prices that can be directly observed or corroborated in active markets; and

•Level 3 - unobservable inputs that are supported by little or no market activity that are significant to the fair value measurement.

Total financial assets carried at fair value			$	145,690					$	1,602,877					$	1,748,567

When available, we value marketable securities based on quoted prices for those financial instruments, which is a Level 1 input. Our remaining marketable securities are valued using third-party pricing sources, which use observable market prices, interest rates and yield curves observable at commonly quoted intervals for similar assets as observable inputs for pricing, which is a Level 2 input.

The carrying amount of our remaining financial assets and liabilities, which include receivables and payables, approximate their fair values due to their short-term nature.

Forward Foreign Currency Contracts

We may enter into forward foreign currency exchange contracts that are not designated as hedges for accounting purposes to hedge certain operational exposures for the changes in foreign currency exchange rates associated with assets or liabilities denominated in foreign currencies, primarily the Euro. Our outstanding forward contracts are generally short-term in nature with maturities of less than three months and are included in other current liabilities in the accompanying Condensed Consolidated Balance Sheets and are considered as Level 2 in the fair value hierarchy of our fair value measurements. Any net realized gains (losses) recognized on the maturity of forward contracts are included in other income (expenses), net on our accompanying Condensed Consolidated Statements of Income.

As of June 30, 2025, there were no forward contracts outstanding. As of December 31, 2024, we had one forward contract outstanding to sell €3.6 million. The net realized gains (losses) we recognized on the maturity of forward contracts were immaterial for each of the three and six months ended June 30, 2025 and 2024.

NOTE 8. STOCKHOLDERS’ EQUITY

Stock-based Compensation

We have an equity incentive plan under which we granted stock options and restricted stock units (RSUs), including market condition-based RSUs and performance-based RSUs (PSUs) to employees and directors. As of June 30, 2025, 9.8 million shares were available for grant under the Exelixis, Inc. 2017 Equity Incentive Plan (as amended and restated, the 2017 Plan). The share reserve is reduced by 1 share for each share issued pursuant to a stock option and 2 shares for full value awards, including RSUs and PSUs.

We allocated the stock-based compensation for our 2017 Plan and our 2000 Employee Stock Purchase Plan (as amended and restated, the Amended ESPP) as follows (in thousands):

			Three Months Ended June 30,												Six Months Ended June 30,
			2025						2024						2025						2024
Research and development			$	14,143					$	9,178					$	23,665					$	13,070

Total stock-based compensation			$	36,071					$	25,354					$	62,001					$	44,467

Stock-based compensation for each type of award under our 2017 Plan and Amended ESPP were as follows (in thousands):

			Three Months Ended June 30,												Six Months Ended June 30,
			2025						2024						2025						2024
Stock options			$	671					$	1,524					$	1,731					$	3,262
Restricted stock units			34,626						22,164						57,728						37,598
Performance stock units			—						1,097						241						1,824
Employee stock purchase plan			774						569						2,301						1,783
Total stock-based compensation			$	36,071					$	25,354					$	62,001					$	44,467

As of June 30, 2025, there were 2.9 million stock options outstanding and $2.5 million of related unrecognized stock-based compensation.

In February 2025, we awarded to certain employees an aggregate of 1.0 million RSUs (the target number) that are subject to a total shareholder return (TSR) market condition and a time-based service condition (the 2025 TSR-based RSUs). The TSR market condition is based on our relative TSR percentile rank compared to companies in the Nasdaq Biotechnology Index during the performance period, which is January 4, 2025 through December 31, 2027. Depending on the results relative to the TSR market condition, the holders of the 2025 TSR-based RSUs may earn up to 175% of the target number of

18

Table of Contents

shares. Following achievement of the market condition at the end of the performance period and upon employee’s continuous service through the vesting dates, 50% of the shares earned pursuant to the 2025 TSR-based RSUs will vest shortly after the end of the performance period, and the remainder will vest approximately one year later. The 2025 TSR-based RSUs will be forfeited if the market condition at or above a threshold level is not achieved, and/or the time-based service condition is not fulfilled, by the end of the performance period and through the vesting dates.

In March 2025, we awarded to employees an aggregate of 6.9 million RSUs that are subject to a stock price appreciation market condition and a time-based service condition (the 2025 stock price target-based RSUs). The market condition will be satisfied to the extent that the volume-weighted average closing price of our common stock for any consecutive 90-calendar-day period equals or exceeds $60 per share on any day during the five-year performance period. Following achievement of the market condition, the 2025 stock price target-based RSUs will vest upon employee’s continuous service through the end of the performance period on March 31, 2030 (the time-based service condition). The 2025 stock price target-based RSUs will be forfeited if the market condition at or above the target price is not achieved, and/or the time-based service condition is not fulfilled, by the end of the performance period.

We used a Monte Carlo simulation model and the following assumptions to determine the grant date fair value of $47.58 per share for the 2025 TSR-based RSUs and $25.10 per share for the 2025 stock price target-based RSUs:

			2025 TSR-based RSUs						2025 stock price target-based RSUs
Fair value of Exelixis common stock on grant date			$	37.53					$	36.92
Expected volatility			32.6		%				38.3		%
Risk-free interest rate			4.0		%				3.9		%
Dividend yield			—		%				—		%

The Monte Carlo simulation model for our 2025 TSR-based RSUs assumed correlations of returns of the stock prices of Exelixis common stock and the common stock of a peer group of companies and historical stock price volatility of the peer group of companies. The valuation model also used terms based on the length of the performance period and compound annual growth rate goals for TSR based on the provisions of the awards. The Monte Carlo simulation model for our 2025 stock price target-based RSUs assumed historical stock price volatility and compounded risk-free rate over the length of the performance period. Stock-based compensation related to RSUs with a market condition is recognized regardless of the outcome of the market condition.

During the six months ended June 30, 2025, we granted 2.5 million service-based RSUs with a weighted- average grant date fair value of $37.26 per share. As of June 30, 2025, there were 20.5 million RSUs outstanding, including RSUs that are subject to market conditions, and $406.8 million of related unrecognized stock-based compensation. Service-based RSUs granted to employees during the six months ended June 30, 2025, have vesting conditions and contractual lives of a similar nature to those described in “Note 9. Stockholders’ Equity” of the “Notes to Consolidated Financial Statements” included in Part II, Item 8 of our Fiscal 2024 Form 10-K.

Common Stock Repurchases

In August 2024, our Board of Directors authorized a stock repurchase program to acquire up to $500.0 million of our outstanding common stock before December 31, 2025. In February 2025, our Board of Directors authorized the repurchase of up to an additional $500.0 million of our outstanding common stock before December 31, 2025. Under these programs, as of June 30, 2025, we repurchased 21.7 million shares of common stock for an aggregate purchase price of $796.3 million. As of June 30, 2025, approximately $203.7 million remained available for future stock repurchases before December 31, 2025.

Stock repurchases under these programs may be made from time to time through a variety of methods, which may include open market purchases, in block trades, Rule 10b5-1 trading plans, accelerated share repurchase transactions, exchange transactions, or any combination of such methods. The timing and amount of any stock repurchases under the stock repurchase programs will be based on a variety of factors, including ongoing assessments of the capital needs of the business, alternative investment opportunities, the market price of our common stock and general market conditions. The programs do not obligate us to acquire any amount of our common stock, and the stock repurchase programs may be modified, suspended or discontinued at any time without prior notice.

NOTE 9. PROVISION FOR INCOME TAXES

The effective tax rates for the three and six months ended June 30, 2025 were 19.8% and 21.0%, respectively, as compared to 22.8% and 23.0%, respectively, for the corresponding periods in 2024. The effective tax rate for the three months ended June 30, 2025, differed from the U.S. federal statutory tax rate of 21%, primarily due to excess tax benefits related to certain stock grants and the generation of federal tax credits, partially offset by state taxes. The effective tax rate for the six months ended June 30, 2025 differed from the U.S. federal statutory rate of 21%, primarily due to state taxes, offset by excess tax benefits related to certain stock grants and the generation of federal tax credits. The effective tax rate for the three and six months ended June 30, 2024, differed from the U.S. federal statutory tax rate of 21%, primarily due to state taxes, offset by the generation of federal tax credits.

Basic net income per share is computed using the weighted-average number of common shares outstanding during the periods. The diluted net income per share is computed using the weighted-average number of common shares outstanding and dilutive potential common shares outstanding during the periods. Dilutive common shares outstanding includes the dilutive effect of in-the-money options, unvested RSUs (including market conditions-based RSUs), unvested PSUs when the performance condition is met and ESPP contributions. The dilutive effect of such equity awards is calculated based on the average share price for each fiscal period using the treasury stock method.

Certain potential common shares were excluded from our calculation of weighted-average common shares outstanding — diluted because either they would have had an anti-dilutive effect on net income per share or they were related to shares from PSUs or from market conditions-based RSUs that were contingently issuable, and the contingency had not been satisfied at the end of the reporting period.

The weighted-average potential common shares excluded from our calculation were as follows (in thousands):

			Three Months Ended June 30,												Six Months Ended June 30,
			2025						2024						2025						2024
Anti-dilutive securities and contingently issuable shares excluded			1,890						8,788						1,718						8,840

Legal Proceedings

MSN ANDA Litigation

In September 2019, we received a notice letter regarding an Abbreviated New Drug Application (ANDA) submitted to the FDA by MSN Pharmaceuticals, Inc. (individually and collectively with certain of its affiliates, including MSN

Table of Contents

Laboratories Private Limited, referred to as MSN), requesting approval to market a generic version of CABOMETYX tablets. MSN’s initial notice letter included a Paragraph IV certification with respect to our U.S. Patents No. 8,877,776, salt and polymorphic forms (the ’776 Patent), 9,724,342, formulations (the ’342 Patent), 10,034,873, methods of treatment (the ’873 Patent), and 10,039,757, methods of treatment (the ’757 Patent), which are listed in the Approved Drug Products with Therapeutic Equivalence Evaluations, also referred to as the Orange Book, for CABOMETYX. MSN’s initial notice letter did not provide a Paragraph IV certification against U.S. Patents No. 7,579,473, composition of matter (the ’473 Patent) or 8,497,284, methods of treatment (the ’284 Patent), each of which is listed in the Orange Book. On October 29, 2019, we filed a complaint in the United States District Court for the District of Delaware (the Delaware District Court) for patent infringement against MSN asserting infringement of the ’776 Patent arising from MSN’s ANDA filing with the FDA. On November 20, 2019, MSN filed its response to the complaint, alleging that the asserted claims of the ’776 Patent are invalid and not infringed. On May 5, 2020, we received notice from MSN that it had amended its ANDA to include additional Paragraph IV certifications and to request approval to market a generic version of CABOMETYX tablets prior to expiration of the two previously unasserted ’473 and ’284 Patents. On May 11, 2020, we filed a complaint in the Delaware District Court for patent infringement against MSN asserting infringement of these patents, and on May 22, 2020, MSN filed its response, alleging that the asserted claims of these patents are invalid and not infringed. On March 23, 2021, MSN filed its First Amended Answer and Counterclaims (amending its prior filing from May 22, 2020), seeking, among other things, a declaratory judgment that U.S. Patent No. 9,809,549, salt and polymorphic forms (the ’549 Patent) is invalid and would not be infringed by MSN if its generic version of CABOMETYX tablets were approved by the FDA. This ’549 Patent is not listed in the Orange Book. On April 7, 2021, we filed our response to MSN’s First Amended Answer and Counterclaims, denying, among other things, that the ’549 Patent is invalid or would not be infringed. The two lawsuits comprising this litigation (collectively referred to as MSN I), numbered Civil Action Nos. 19-02017 and 20-00633, were consolidated in April 2021.

A bench trial for MSN I occurred in May 2022, and on January 19, 2023, the Delaware District Court issued a ruling rejecting MSN’s invalidity challenge to the ’473 Patent. The Delaware District Court also ruled that MSN’s proposed ANDA product does not infringe the ’776 Patent. In accordance with these rulings, the Delaware District Court entered judgment that the effective date of any final FDA approval of MSN’s ANDA shall not be a date earlier than August 14, 2026, the expiration date of the ’473 Patent. Final judgment was entered on January 30, 2023. This ruling in MSN I did not impact our separate MSN II lawsuit (as defined below).

On January 11, 2022, we received notice from MSN that it had further amended its ANDA to assert additional Paragraph IV certifications. In particular, the January 11, 2022 amended ANDA requested approval to market a generic version of CABOMETYX tablets prior to expiration of three previously-unasserted CABOMETYX patents that are now listed in the Orange Book: U.S. Patents No. 11,091,439, crystalline salt forms (the ’439 Patent), 11,091,440, pharmaceutical composition (the ’440 Patent), and 11,098,015, methods of treatment (the ’015 Patent). On February 23, 2022, we filed a complaint in the Delaware District Court for patent infringement against MSN asserting infringement of the ’439, ’440, and ’015 Patents arising from MSN’s further amendment of its ANDA filing with the FDA. On February 25, 2022, MSN filed its response to the complaint, alleging that the asserted claims of the ’439, ’440, and ’015 Patents are invalid and not infringed. On June 7, 2022, we received notice from MSN that it had further amended its ANDA to assert an additional Paragraph IV certification. As currently amended, MSN’s ANDA now requests approval to market a generic version of CABOMETYX tablets prior to expiration of a previously-unasserted CABOMETYX patent that is now listed in the Orange Book: U.S. Patent No. 11,298,349, pharmaceutical composition (the ’349 Patent). On July 18, 2022, we filed a complaint in the Delaware District Court for patent infringement against MSN asserting infringement of the ’349 Patent arising from MSN’s further amendment of its ANDA filing with the FDA. On August 9, 2022, MSN filed its response to the complaint, alleging that the asserted claims of the ’349 Patent are invalid and not infringed and amended its challenges to the ’439, ’440, and ’015 Patents to allege that these patents are not enforceable based on equitable grounds. The two lawsuits comprising this litigation (collectively referred to as MSN II), numbered Civil Action Nos. 22-00228 and 22-00945, were consolidated in October 2022 and involve Exelixis patents that are different from those asserted in the MSN I litigation described above.

On June 21, 2022, pursuant to a stipulation between us and MSN, the Delaware District Court entered an order that (i) MSN’s submission of its ANDA constitutes infringement of certain claims relating to the ’439, ’440, and ’015 Patents, if those claims are not found to be invalid, and (ii) upon approval, MSN’s commercial manufacture, use, sale or offer for sale within the U.S., and importation into the U.S., of MSN’s proposed ANDA product prior to the expiration of these patents would also infringe certain claims of each patent, if those claims are not found to be invalid. In our MSN II complaints, we sought, among other relief, an order that the effective date of any FDA approval of MSN’s ANDA would be a date no earlier than the expiration of the ’439, ’440, ’015, and ’349 Patents, the latest of which expires on February 10, 2032, and equitable relief enjoining MSN from infringing these patents. On September 28, 2023, the Delaware District Court granted the parties’ stipulation of dismissal of MSN’s equitable defenses and counterclaims. A bench trial occurred in October 2023, and on

Table of Contents

October 15, 2024, the Delaware District Court issued a ruling rejecting MSN’s invalidity challenge to each of the ’439, ’440, and ’015 Patents. The Delaware District Court also ruled that the ’349 Patent is not invalid and that MSN’s proposed ANDA product does not infringe this patent. In accordance with these rulings, the Delaware District Court entered final judgment on October 23, 2024, that, should the FDA ultimately approve MSN’s ANDA, the effective date of any such approval of MSN’s ANDA shall not be a date earlier than January 15, 2030, the expiration date of each of the ’439, ’440, and ’015 Patents, subject to our potential additional regulatory exclusivity.

On November 22, 2024, MSN noticed an appeal to the Court of Appeals for the Federal Circuit (CAFC) and we noticed a cross-appeal on November 26, 2024. On April 1, 2025, MSN filed its Opening Brief arguing that the asserted claims of the ’439, ’440, ’015, and ’349 Patents are invalid. On June 10, 2025, the CAFC granted our request to dismiss our cross-appeal. On June 11, 2025, we filed our Response Brief.

In February 2025, we received another notice letter from MSN regarding its ANDA, requesting FDA approval to market a generic version of CABOMETYX tablets. MSN’s notice letter included a Paragraph IV certification with respect to Orange Book-listed patent U.S. Patent No. 12,128,039, low impurity (the ’039 Patent), which expires in 2032. On March 19, 2025, we filed a complaint in the Delaware District Court for patent infringement against MSN asserting infringement of this patent arising from MSN’s further amendment of its ANDA filing with the FDA. On April 10, 2025, MSN filed its response to the complaint, alleging that the asserted claims of the ’039 Patent are invalid, unenforceable, and not infringed. On May 1, 2025, we filed our answer to MSN’s counterclaim.

Sun ANDA Litigation

On September 17, 2024, we received a notice letter regarding an ANDA submitted to the FDA by Sun Pharmaceutical Industries Ltd. (Sun), requesting approval to market a generic version of CABOMETYX tablets. Sun’s notice letter included a Paragraph IV certification with respect to the ’776 Patent, the ’342 Patent, the ’873 Patent, the ’757 Patent, the ’439 Patent, the ’440 Patent, the ’015 Patent, and the ’349 Patent, which are listed in the Orange Book, for CABOMETYX. On October 30, 2024, we filed a complaint in the Delaware District Court for patent infringement against Sun asserting infringement of the ’776, ’439, ’440, and ’015 Patents. On January 22, 2025, Sun filed its response to the complaint, alleging that the asserted claims of the patents at issue are invalid and not infringed. Sun also filed counterclaims that, inter alia, seek a declaratory judgment that Sun’s ANDA would not infringe any valid and enforceable claim of the ’776, ’439, ’440, ’015, ’342, ’873, ’757, and ’349 Patents. On January 22, 2025, we filed our answer to Sun’s counterclaims. Trial in this matter has been scheduled for November 2, 2026.

In February 2025, we received another notice letter from Sun regarding its ANDA, requesting FDA approval to market a generic version of CABOMETYX tablets. Sun’s notice letter included a Paragraph IV certification with respect to Orange Book-listed ’039 Patent, which expires in 2032. On April 4, 2025, we filed a complaint in the Delaware District Court for patent infringement against Sun asserting infringement of the ’039 Patent arising from Sun’s amendment of its ANDA filing with the FDA. On June 9, 2025, Sun filed its response to the complaint, alleging that the asserted claims of the ’039 Patent are invalid, unenforceable, and not infringed. On June 30, 2025, we filed our answer to Sun’s counterclaim.

Biocon ANDA Litigation

In March 2025, we received a notice letter regarding an ANDA submitted to the FDA by Biocon Pharma Limited (Biocon), requesting approval to market a generic version of CABOMETYX tablets. Biocon’s notice letter included a Paragraph IV certification with respect to the ’776 Patent, the ’342 Patent, the ’873 Patent, the ’757 Patent, the ’439 Patent, the ’440 Patent, the ’015 Patent, the ’349 Patent, and the ’039 Patent which are listed in the Orange Book, for CABOMETYX. On April 11, 2025, we filed a complaint in the Delaware District Court for patent infringement against Biocon asserting infringement of the ’776, ’439, ’440, ’015, and ’039 Patents. On June 19, 2025, Biocon filed its response to the complaint, alleging that the asserted claims of the patents at issue are invalid and not infringed. On July 10, 2025, we filed our answer to Biocon’s counterclaims. In July 2025, we entered into a settlement and license agreement with Biocon (the Biocon Settlement Agreement). Pursuant to the terms of the Biocon Settlement Agreement, Exelixis will grant Biocon a license to market its generic version of CABOMETYX in the United States beginning on January 1, 2031, if approved by the FDA and subject to conditions and exceptions common to agreements of this type. Additionally, in accordance with the Biocon Settlement Agreement, the parties will terminate all ongoing Hatch-Waxman litigation between Exelixis and Biocon regarding CABOMETYX patents pending in the U.S. District Court for the District of Delaware. The Biocon Settlement Agreement is confidential and subject to review by the U.S. Federal Trade Commission and the U.S. Department of Justice.

Azurity 505(b)(2) NDA Litigation

In March 2025, we received a notice letter regarding a 505(b)(2) New Drug Application (505(b)(2)) submitted to the FDA by Azurity Pharmaceuticals, Inc. (Azurity), requesting approval to market cabozantinib (S)-malate tablets. Azurity’s notice letter included a Paragraph IV certification with respect to the ’776 Patent, the ’342 Patent, the ’873 Patent, the ’757 Patent, the ’439 Patent, the ’440 Patent, the ’015 Patent, the ’349 Patent, and the ’039 Patent which are listed in the Orange Book, for CABOMETYX. On April 18, 2025, we filed a complaint in the Delaware District Court for patent infringement against Azurity asserting infringement of the ’776, ’439, ’440, ’015, ’349, and ’039 Patents. On April 24, 2025, we filed our First Amended Complaint alleging infringement of the same patents. On June 11, 2025, Azurity filed its response to the complaint, alleging that the asserted claims of the patents at issue are not infringed and/or invalid. On July 2, 2025, we filed our answer to Azurity’s counterclaims.

Other

On November 18, 2024, Azurity filed a petition seeking inter partes review of the ’349 Patent at the United States Patent and Trademark Office (USPTO). The proceeding was accorded a filing date of December 12, 2024. On June 4, 2025, the USPTO declined to institute Azurity’s inter partes review of the ’349 Patent and the deadline for Azurity to seek rehearing has passed.

On January 9, 2025, Azurity filed a petition seeking inter partes review of the ’039 Patent at the USPTO. The proceeding was accorded a filing date of March 6, 2025. On July 2, 2025, the USPTO declined to institute Azurity’s inter partes review of the ’039 Patent.

The sale of any cabozantinib (S)-malate tablets besides CABOMETYX significantly earlier than CABOMETYX’s patent expiration could decrease our revenues derived from the U.S. sales of CABOMETYX and thereby materially harm our business, financial condition and results of operations. It is not possible at this time to determine the likelihood of an unfavorable outcome or estimate of the amount or range of any potential loss.

We may also from time-to-time become a party or subject to various other legal proceedings and claims, either asserted or unasserted, which arise in the ordinary course of business. Some of these proceedings have involved, and may involve in the future, claims that are subject to substantial uncertainties and unascertainable damages.

Overview

We are an oncology company innovating next-generation medicines and combination regimens at the forefront of cancer care. We have produced four marketed pharmaceutical products, two of which are formulations of our flagship molecule, cabozantinib, and we are steadily advancing and evolving our product pipeline portfolio, including our lead asset zanzalintinib, currently the focus of an extensive late-stage clinical development program. With a rational and disciplined approach to investment, we are leveraging our internal experience and expertise, and the strength of strategic

23

Table of Contents

partnerships, to identify and pursue opportunities across the landscape of scientific modalities, including small molecules, biotherapeutics and antibody-drug conjugates (ADCs).

Sales related to cabozantinib account for the majority of our revenues. Cabozantinib is an inhibitor of multiple tyrosine kinases, including MET, AXL, VEGF receptors and RET and has been approved by the U.S. Food and Drug Administration (FDA) as CABOMETYX® (cabozantinib) tablets for: advanced renal cell carcinoma (RCC) (both alone and in combination with Bristol-Myers Squibb Company’s (BMS) nivolumab (OPDIVO®)), previously treated hepatocellular carcinoma (HCC), previously treated, radioactive iodine (RAI)-refractory differentiated thyroid cancer (DTC), and previously treated, unresectable, locally advanced or metastatic, well-differentiated pancreatic neuroendocrine tumors (pNET) and extra-pancreatic neuroendocrine tumors (epNET); and as COMETRIQ® (cabozantinib) capsules for progressive, metastatic medullary thyroid cancer (MTC). Additionally, CABOMETYX is approved in 68 other countries for all or a combination of the following: advanced RCC, previously treated HCC, previously treated RAI-refractory DTC, and/or previously treated, well-differentiated/unresectable, locally advanced, or metastatic pNET or epNET; and as COMETRIQ for progressive MTC. For physicians treating these types of cancer, cabozantinib has become or is becoming an important medicine in their selection of effective therapies.

The other two products resulting from our discovery efforts are: COTELLIC® (cobimetinib), an inhibitor of MEK, approved as part of multiple combination regimens to treat specific forms of advanced melanoma and marketed under a collaboration with Genentech, Inc. (a member of the Roche Group); and MINNEBRO® (esaxerenone), an oral, non-steroidal, selective blocker of the mineralocorticoid receptor, approved for the treatment of hypertension in Japan and licensed to Daiichi Sankyo Company, Limited.

We plan to continue leveraging our operating cash flows to advance a broad array of diverse biotherapeutics and small molecule programs for the treatment of cancer, as well as to support ongoing company-sponsored and externally sponsored trials evaluating cabozantinib. Furthest along in our pipeline is zanzalintinib, a novel, potent, third-generation oral tyrosine kinase inhibitor (TKI) that targets VEGF receptors, MET and the TAM kinases (TYRO3, AXL and MER). Our zanzalintinib program includes a series of ongoing and planned pivotal trials to explore its therapeutic potential in colorectal cancer (CRC), RCC and NET, as well as earlier-stage trials. Our other pipeline programs in phase 1 development each have best-in-class potential and include: XL309, a small molecule inhibitor of USP1, which has emerged as a synthetic lethal target in the context of BRCA-mutated tumors; XB010, an ADC consisting of a MMAE payload conjugated to a human mAb targeting the tumor antigen 5T4; and XB628, a first-in-class bispecific antibody that simultaneously targets PD-L1 and natural killer cell receptor group 2A, identified as key regulators of innate and adaptive immune cell activity. We complement our internal drug discovery and development efforts by in-licensing or acquiring, or obtaining options to in-license or acquire, investigational oncology assets from third parties if those oncology assets demonstrate evidence or potential of clinical success. Examples of this approach include XL309 and ADU-1805, a clinical-stage and potentially best-in-class human mAb that targets SIRPα.

Cabozantinib Franchise

The FDA first approved CABOMETYX in the U.S. as a monotherapy for previously treated patients with advanced RCC in April 2016, and then for previously untreated patients with advanced RCC in December 2017. In January 2021, the CABOMETYX label was expanded to include first-line advanced RCC in combination with nivolumab, which was the first CABOMETYX regimen approved for treatment in combination with an immune checkpoint inhibitor (ICI). In addition to RCC, in January 2019, the FDA approved CABOMETYX for the treatment of patients with HCC previously treated with sorafenib, and in September 2021, the FDA approved CABOMETYX for the treatment of adult and pediatric patients 12 years of age and older with locally advanced or metastatic DTC that has progressed following prior VEGF receptor-targeted therapy and who are RAI-refractory or ineligible. In March 2025, the FDA approved CABOMETYX for the treatment of adult and pediatric patients 12 years of age and older with previously treated, unresectable, locally advanced or metastatic, well-differentiated pNET and epNET.

The Inflation Reduction Act of 2022 (IRA) introduced numerous substantial changes to drug pricing, reimbursement and access support in the U.S., including enabling the Centers for Medicare & Medicaid Services (CMS) to assert control over the prices of certain single-source drugs and biotherapeutics reimbursed under Medicare Part B and Part D (the Medicare Drug Price Negotiation Program). The IRA contains a limited exception for small biotech drug manufacturers, which applies on a drug-specific basis, and provides that qualifying drugs will be exempt from selection for pricing negotiation through 2028 and eligible for a lower limit (i.e., a price floor) on the potential maximum fair price in 2029 and 2030, if the manufacturers of those drugs continue to qualify each year (small biotech exception). We have qualified for the small biotech exception with respect to our cabozantinib franchise products through 2027, and we intend to apply to CMS

24

Table of Contents

to maintain the small biotech exception each year through 2030. Separately, in December 2024, CMS released final guidance on another program, the Medicare Part D Manufacturer Discount Program (Part D Discount Program), which requires manufacturers to take on more of the beneficiary cost previously subsidized by the federal government through the application of increased drug discounts. We have since received notice from CMS that we qualify for the "specified small manufacturer” designation and are thereby eligible for a phase-in of the increased manufacturer discounts under the Part D Discount Program, from 2025 to 2031.

To develop and commercialize cabozantinib outside the U.S., we have entered into license agreements with Ipsen Pharma SAS (Ipsen) and Takeda Pharmaceutical Company Limited (Takeda). To Ipsen, we granted the rights to develop and commercialize cabozantinib outside of the U.S. and Japan, and to Takeda we granted such rights in Japan. Both Ipsen and Takeda also contribute financially and operationally to the further global development and commercialization of the cabozantinib franchise, and we work closely with them on these activities. Utilizing its regulatory expertise and established international oncology marketing network, Ipsen has continued to execute on its commercialization plans for CABOMETYX, having received regulatory approvals and launched in multiple territories outside of the U.S., including in the European Economic Area (EEA, which covers all 27 member states of the European Union and Norway, Lichtenstein and Iceland), the United Kingdom and Canada, as a treatment for advanced RCC (both as a monotherapy and in combination with nivolumab) and for previously treated HCC and DTC indications. In July, Ipsen received approval from the European Commission (EC) for the EEA, and health regulatory authorities in both Brazil and Australia for CABOMETYX as a treatment for previously treated, well-differentiated/unresectable, locally advanced, or metastatic pNET or epNET (with local labeling variations). With respect to the Japanese market, Takeda received Manufacturing and Marketing Approvals from the Japanese Pharmaceuticals and Medical Devices Agency for monotherapy CABOMETYX as a treatment of patients with curatively unresectable or metastatic RCC and as a treatment of patients with unresectable HCC that has progressed after cancer chemotherapy, as well as for CABOMETYX in combination with nivolumab as a treatment for unresectable or metastatic RCC.

Building on preclinical and clinical observations that cabozantinib in combination with ICIs may promote a more immune-permissive tumor environment, we initiated several pivotal studies to further explore these combination regimens, including collaborations with F. Hoffmann-La Roche Ltd. (Roche) and BMS. In August 2023, we announced positive top-line results from CONTACT-02, a phase 3 pivotal trial sponsored by us and co-funded by Roche, evaluating the combination of cabozantinib and Roche’s ICI, atezolizumab, versus a second novel hormonal therapy (NHT) in patients with measurable, extra-pelvic metastatic castration-resistant prostate cancer (mCRPC) who have progressed after treatment with one prior NHT. The trial met one of two primary endpoints, demonstrating a statistically significant improvement in the predefined progression-free survival intent-to-treat population (ITT) (i.e., the first 400 randomized patients), and these data were presented at the American Society of Clinical Oncology (ASCO) Genitourinary Cancers Symposium in January 2024. For the second primary endpoint of overall survival (OS), the final analysis for CONTACT-02, which was presented during the GU Tumours Proffered Paper Session at the European Society for Medical Oncology Congress in September 2024, a trend favoring the combination of cabozantinib and atezolizumab was shown; however, it was not statistically significant. Based on these results and the evolution of the treatment landscape in mCRPC, Exelixis does not intend to file a supplemental New Drug Application for CONTACT-02.

Pipeline Activities

Zanzalintinib

Zanzalintinib is a novel, potent, third-generation oral TKI that targets VEGF receptors, MET and the TAM kinases (TYRO3, AXL and MER) implicated in cancer’s growth and spread, and is our first in-house compound to enter the clinic following our re-initiation of drug discovery activities in 2017. We are evaluating zanzalintinib in a growing development program that builds on our prior experience with cabozantinib and targets indications with high unmet need. We have established collaborations and will continue to explore additional opportunities for novel combinations with zanzalintinib. To date, we have initiated two large phase 1b/2 clinical trials studying zanzalintinib as a monotherapy and in combination with ICIs (STELLAR-001 and STELLAR-002). Patient enrollment into STELLAR-001 was completed in 2023, and preliminary results from a randomized expansion cohort of patients with metastatic CRC were presented at the ASCO Gastrointestinal Cancers Symposium in January 2025. In May 2025, preliminary results from an expansion cohort of patients with previously untreated advanced clear cell RCC from STELLAR-002 were presented at the 2025 American Society of Clinical Oncology Annual Meeting (ASCO 2025), along with data from multiple dose-escalation cohorts.

We have also initiated four pivotal trials, three evaluating zanzalintinib in combination with ICIs and one evaluating zanzalintinib as a monotherapy. Our first such trial, STELLAR-303, was initiated in June 2022 and is evaluating zanzalintinib

25

Table of Contents

in combination with atezolizumab versus regorafenib in patients with metastatic, refractory non-microsatellite instability-high or non-mismatch repair-deficient (non-MSI-H/dMMR) CRC. In June 2025, we announced positive top-line results demonstrating a statistically significant improvement in OS versus regorafenib in all patients (i.e., in the ITT population). This represents the final OS analysis in the ITT population. The trial will proceed to the planned final analysis for the other dual primary endpoint of OS in patients without liver metastases (non-liver metastases or NLM). We intend to discuss these positive results with regulators with the intention to file a New Drug Application in the U.S. Detailed results are expected to be presented at a future medical meeting.

The second pivotal trial, STELLAR-304, was initiated in December 2022 and is evaluating zanzalintinib in combination with nivolumab versus sunitinib in previously untreated patients with advanced non-clear cell RCC. We expect top-line results in the first half of 2026, depending on event rates.

In December 2023, we initiated STELLAR-305, a phase 2/3 pivotal trial evaluating zanzalintinib in combination with pembrolizumab (KEYTRUDA®), an anti-PD-1 ICI developed by Merck & Co., Inc., versus placebo in combination pembrolizumab in patients with previously untreated PD-L1-positive recurrent or metastatic squamous cell carcinoma of the head and neck (SCCHN). Based on our evaluation of emerging data from the phase 2 portion of STELLAR-305, competition in this indication, and assessment of other, potentially larger, commercial opportunities, the study will not proceed to phase 3.

In June 2025, we initiated STELLAR-311, a phase 3 pivotal trial evaluating zanzalintinib versus everolimus as a first oral therapy in patients with advanced NET, regardless of site of origin.

To further expand our exploration of the clinical potential of zanzalintinib, we entered into a clinical development collaboration with MSD International Business GmbH, known as Merck within the United States and Canada (Merck) to evaluate zanzalintinib in combination with WELIREG® (belzutifan), Merck's oral HIF-2α inhibitor, in RCC as well as in combination with KEYTRUDA® in SCCHN. Under the collaboration, we continue to retain all global commercial and marketing rights to zanzalintinib. Merck will sponsor a phase 1/2 trial and two phase 3 pivotal trials in RCC and will fund one of these phase 3 studies; we will co-fund the phase 1/2 study and the other phase 3 study, as well as supply zanzalintinib and cabozantinib.

We intend to initiate additional pivotal trials evaluating zanzalintinib across a broad array of future potential indications.

Biotherapeutics

Part of our drug discovery activity focuses on discovering and advancing various biotherapeutics that have the potential to become anti-cancer therapies, such as bispecific antibodies, ADCs and other innovative treatments. ADCs in particular present a unique opportunity for new cancer treatments, given their capabilities to target the delivery of anti-cancer drug payloads to specific cells expressing the target; this increased precision should minimize collateral impact on healthy tissues that do not express the target. To facilitate the growth of our various biotherapeutics programs, we have established multiple research collaborations and in-licensing arrangements and have entered into other strategic transactions aimed at conserving capital and managing risks, collectively providing us access to antibodies, binders, payloads and conjugation technologies to generate next-generation ADCs or multispecific antibodies.

As part of our strategy to access clinical- or near-clinical-stage assets, we executed an exclusive option and license agreement and clinical development collaboration with Sairopa B.V. (Sairopa) to develop ADU-1805. ADU-1805 is currently being evaluated in a phase 1 clinical trial in patients with advanced or metastatic refractory solid tumors, as monotherapy and in combination with pembrolizumab. Enrollment is ongoing. In addition to the option deal with Sairopa, some of our active collaborations for biotherapeutics programs are with:

•Adagene Inc. (Adagene), which is focused on using Adagene’s SAFEbodyTM technology to develop novel masked ADCs or other innovative biotherapeutics with potential for improved therapeutic index;

•Catalent, Inc. (Catalent), which is focused on the discovery and development of multiple ADCs using Catalent’s proprietary SMARTag® site-specific bioconjugation technology; and

•Invenra, Inc. (Invenra), which is focused on the discovery and development of novel binders and multispecific antibodies for the treatment of cancer.

We have made significant progress under our research collaborations and in-licensing arrangements and believe we will continue to do so in 2025 and in future years. For example, in April 2025, we initiated the phase 1 study of XB628, a

first-in-class bispecific antibody discovered, in part, in collaboration with Invenra, and in July 2025, the FDA accepted our Investigational New Drug (IND) application for XB371, a next-generation tissue factor-targeting ADC with a topoisomerase inhibitor payload, which was discovered, in part, in collaboration with Catalent. We are also advancing additional biotherapeutic candidates toward potential IND filings, each of which was discovered, in part, in connection with our research collaborations and in-licensing arrangements, including: XB064, a high-affinity mAb that targets ILT2; XB033, an ADC targeting the tumor antigen IL13Rα2; and XB773, an ADC targeting the tumor antigen DLL3.

Other Small Molecules

The knowledge and experience gained through our efforts to discover cabozantinib, cobimetinib and esaxerenone, each of which were approved by regulatory authorities and are commercially distributed, informs our current strategy for discovering and developing additional small molecules with the potential to treat cancer, including XL309, a potentially best-in-class small molecule inhibitor of USP1, a synthetic lethal target in the context of BRCA-mutated tumors. XL309 is currently being evaluated in a phase 1 clinical trial as monotherapy and in combination with PARP1/2 inhibition in patients with advanced solid tumors and enrollment is ongoing. XL309 has potential in patients whose tumors are no longer responsive to PARP inhibitors (PARPi), including ovarian, breast and prostate cancers, and also has potential in combination with PARPi agents to deepen and prolong the response seen to PARPi, as well as to broaden the activity beyond that observed in patients with tumors that harbor a BRCA1/2 mutation.

Beyond these assets, we continue to make progress on multiple lead optimization programs for agents directed toward a variety of targets that we believe play significant roles in tumor biology, and we anticipate that some of these other programs could reach development candidate status in 2025 and beyond.

Future Expansion of our Pipeline

Increasing the number of novel anti-cancer agents in our pipeline is essential to our overall strategy and business goals. We are working to expand our oncology product pipeline through drug discovery efforts, which encompass our diverse biotherapeutics and small molecule programs exploring multiple modalities and mechanisms of action. This approach provides a high degree of flexibility with respect to target selection and modality of treatment and allows us to prioritize those programs that we believe have the greatest chance of delivering impactful therapeutics. As part of our strategy, our drug discovery activities have and will continue to include internal research, as well as external research, collaborations, in-licensing arrangements and other strategic transactions that collectively leverage a wide range of technology platforms and assets and increase our probability of success. As of the date of this Quarterly Report on Form 10-Q, we expect to progress up to two new development candidates into preclinical development later in 2025. We will continue to engage in pipeline expansion initiatives with the goal of discovering, acquiring and/or in-licensing promising investigational oncology assets and then further characterize and develop them utilizing our established preclinical and clinical development infrastructure.

Second Quarter 2025 Business Updates and Financial Highlights

During the second quarter of 2025, we continued to execute on our business objectives, generating significant revenues from operations and enabling us to continue to seek to maximize the clinical and commercial potential of our products and expand our product pipeline. Significant business updates and financial highlights for the quarter and subsequent to quarter-end include:

Business Updates

•In May 2025, we presented preliminary results from an expansion cohort of patients with previously untreated advanced clear cell RCC from STELLAR-002, along with data from multiple dose-escalation cohorts, at ASCO 2025.

•In June 2025, we announced positive top-line results from STELLAR-303 in which zanzalintinib in combination with atezolizumab demonstrated a statistically significant improvement in OS versus regorafenib in the ITT population of patients with previously treated non-MSI-H/dMMR CRC. The trial will proceed to the planned final analysis of the other dual primary endpoint of OS in the NLM patient population.

•In June and July 2025, the USPTO declined to institute Azurity’s inter partes review of U.S. Patent Nos. 11,298,349 and 12,128,039, respectively.

•As of June 30, 2025, we have repurchased $796.3 million of our common stock at an average purchase price of $36.69 per share, under the two $500 million share repurchase authorizations announced in August 2024 and February 2025.

•Net income for the second quarter of 2025 was $184.8 million, or $0.68 per share, basic and $0.65 per share, diluted, as compared to net income of $226.1 million, or $0.78 per share, basic and $0.77 per share, diluted, for the second quarter of 2024.

See “Results of Operations” below for a discussion of the detailed components and analysis of the amounts above.

Outlook, Challenges and Risks

We will continue to face numerous challenges and risks that may impact our ability to execute on our business objectives. In particular, for the foreseeable future, we expect our ability to generate sufficient cash flow to fund our business operations and growth will depend upon the continued commercial success of CABOMETYX, both alone and in combination with other therapies, as a treatment for the highly competitive indications for which it is approved, and possibly for other indications for which cabozantinib is currently being evaluated in potentially label-enabling clinical trials, if warranted by the data generated from these trials. However, we cannot be certain that the clinical trials we and our collaboration partners are conducting will demonstrate adequate safety and efficacy in these additional indications to receive regulatory approval in the major commercial markets where CABOMETYX is approved.

Even if the required regulatory approvals to market CABOMETYX for additional indications are achieved, we and our collaboration partners may not be able to commercialize CABOMETYX effectively and successfully in these additional indications. In addition, CABOMETYX will only continue to be commercially successful if private third-party and government payers continue to provide coverage and reimbursement. As is the case for all innovative pharmaceutical therapies, obtaining and maintaining coverage and reimbursement for CABOMETYX is becoming increasingly difficult, both within the U.S. and in foreign markets. In addition, healthcare policymakers in the U.S. continue to express concern over healthcare costs, and corresponding legislative and policy initiatives and activities have been launched aimed at increasing the healthcare cost burdens borne by pharmaceutical manufacturers, as well as expanding access to, and restricting the prices and growth in prices of, pharmaceuticals. Further, the U.S. Presidential administration has suggested that it may impose tariffs on imported pharmaceuticals.

Achievement of our business objectives will also depend on our ability to maintain a competitive position in the shifting landscape of therapeutic strategies for the treatment of cancer, which we may not be able to do. On an ongoing basis, we assess the constantly evolving landscape of other approved and investigational cancer therapies that could be competitive, or complementary in combination, with our products, and then we adapt our development strategies for the cabozantinib franchise and our pipeline product candidates accordingly, such as by modifying our clinical trials to include evaluation of our therapies with ICIs and other targeted agents. Even if our current and future clinical trials produce positive

28

results sufficient to obtain marketing approval by the FDA and other global regulatory authorities, it is uncertain whether physicians will choose to prescribe regimens containing our products instead of competing products and product combinations in approved indications.

In the longer term, we may eventually face competition from potential manufacturers of generic or other versions of our marketed products, including any cabozantinib (S)-malate tablets besides CABOMETYX that are the subject of ANDAs submitted to the FDA by MSN and Sun or the 505(b)(2) submitted to the FDA by Azurity. The approval of any of these ANDAs and subsequent launch of any generic version of CABOMETYX could significantly decrease our revenues derived from the U.S. sales of CABOMETYX and thereby materially harm our business, financial condition and results of operations.

Separately, our research and development objectives may be impeded by the challenges of scaling our organization to meet the demands of expanded drug development, unanticipated delays in clinical testing and the inherent risks and uncertainties associated with drug discovery operations, especially on the global level. In connection with efforts to expand our product pipeline, we may be unsuccessful in discovering new potential cancer treatments or identifying appropriate candidates for in-licensing or acquisition.

Some of these challenges and risks are specific to our business, others are common to companies in the biopharmaceutical industry with development and commercial operations, and an additional category are macroeconomic, affecting all companies. For a more detailed discussion of challenges and risks we face, see “Risk Factors” in Part I, Item 1A of our 2024 Form 10-K, as supplemented and, to the extent inconsistent or superseded in Part II, Item 1A of our Quarterly Reports on Form 10-Q.

Fiscal Year Convention

We have adopted a 52- or 53-week fiscal year policy that generally ends on the Friday closest to December 31. Fiscal year 2025, which is a 52-week fiscal year, will end on January 2, 2026 and fiscal year 2024, which was a 53-week fiscal year, ended on January 3, 2025. The 52-week fiscal year in 2025 may result in a modest year-over-year impact on revenues and expenses, as compared to 2024. For convenience, references in this report as of and for the fiscal periods ended July 4, 2025 and June 28, 2024, and as of and for the fiscal years ending January 2, 2026 and ended January 3, 2025, are indicated as being as of and for the periods ended June 30, 2025 and June 30, 2024, and the years ending December 31, 2025 and ended December 31, 2024, respectively.

Results of Operations

Revenues

Revenues by category were as follows (dollars in thousands):

			Three Months Ended June 30,												Percent Change						Six Months Ended June 30,												Percent Change

Net Product Revenues

Gross product revenues, discounts and allowances and net product revenues were as follows (dollars in thousands):

			Three Months Ended June 30,												Percent Change						Six Months Ended June 30,												Percent Change
			2025						2024												2025						2024

Net product revenues by product were as follows (dollars in thousands):

			Three Months Ended June 30,												Percent Change						Six Months Ended June 30,												Percent Change
			2025						2024												2025						2024
CABOMETYX			$	517,890					$	433,341					20		%				$	1,028,762					$	809,758					27		%

Net product revenues			$	520,014					$	437,581					19		%				$	1,033,297					$	816,104					27		%

The increases in net product revenues for the three and six months ended June 30, 2025, as compared to the corresponding prior year periods, were primarily related to increases of 20% and 22%, respectively, in the number of CABOMETYX units sold reflecting continuing demand for CABOMETYX in combination with nivolumab as a first-line treatment of patients with advanced RCC. The increases in sales volume were largely driven by refills, reflecting the longer duration of therapy for this combination, and increases in related market share reflecting the continued evolution of the metastatic RCC and NET treatment landscapes.

We project our net product revenues may increase for the remainder of 2025, as compared to the corresponding prior year period, as a result of the FDA’s approval in the first quarter of 2025, of CABOMETYX for patients with previously treated advanced NET and for similar reasons noted above.

We recognize product revenues net of discounts and allowances that are described in “Note 1. Organization and Summary of Significant Accounting Policies” of the “Notes to Consolidated Financial Statements” included in Part II, Item 8 of our Fiscal 2024 Form 10-K.

Discounts and allowances have generally increased over time as the number of patients participating in government programs has increased and as the discounts given and rebates paid to government payers have also increased. The increases in the amount of discounts and allowances for the three and six months ended June 30, 2025, as compared to the corresponding prior year periods, were primarily the result of increases in volume of units sold, and the increases in the dollar amount of chargebacks under the 340B Drug Pricing Program.

We project our discounts and allowances may increase for the remainder of 2025, as compared to the corresponding prior year period, for similar reasons noted above.

License Revenues

License revenues primarily include: (a) the recognition of the portion of milestone payments allocated to the transfer of intellectual property licenses for which it had become probable, in the related period, that a milestone would be achieved and a significant reversal of revenues would not occur in future periods; and (b) royalty revenues.

During the three and six months ended June 30, 2024, $150.0 million in revenues was recognized and allocated to license revenues, in connection with a commercial milestone payment from Ipsen upon its achievement of $600.0 million in cumulative net sales of cabozantinib over four consecutive quarters in its related license territory. Milestone revenues, which are allocated between license revenues and collaboration services revenues, were $151.5 million and $153.0 million, respectively, for the three and six months ended June 30, 2024.

Royalty revenues for the three months ended June 30, 2025 increased, as compared to the corresponding prior year period, primarily as a result of increases in Ipsen’s net sales of cabozantinib outside of the U.S and Japan. Royalty revenues for the six months ended June 30, 2025 were flat, as compared to the corresponding prior year period, as a result of a decrease in Ipsen’s net sales of cabozantinib outside of the U.S. and Japan, that was offset by an increase in other royalty revenues, primarily from Takeda. Ipsen royalties were $39.5 million and $73.5 million, respectively, for the three and six months ended June 30, 2025, as compared to $37.9 million and $74.8 million for the corresponding prior year periods. Royalty revenues for the three and six months ended June 30, 2025 related to Takeda’s net sales of cabozantinib were $3.8 million and $6.6 million, respectively, as compared to $3.3 million and $6.0 million, respectively, for the corresponding prior year periods. CABOMETYX is approved and is commercially available in 68 countries outside the U.S.

Due to uncertainties surrounding the timing and achievement of regulatory and development milestones, it is difficult to predict future milestone revenues and milestones can vary significantly from period to period.

Collaboration Services Revenues

Collaboration services revenues include: (a) the development cost reimbursements earned under our collaboration agreements and product supply revenues, net of product supply costs; (b) the recognition of deferred revenues for the portion of upfront and milestone payments that have been allocated to research and development services performance obligations; offset by (c) the royalties we pay to Royalty Pharma plc (Royalty Pharma) on sales by Ipsen and Takeda of products containing cabozantinib.

Development cost reimbursements decreased in the three and six months ended June 30, 2025, as compared to the corresponding prior year periods, due to decreases in spending on studies evaluating cabozantinib that are subject to reimbursement.

Recognition of deferred revenues for the portion of upfront and milestone payments that have been allocated to research and development services performance obligations were not material in the three and six months ended June 30, 2025 and 2024, respectively.

Collaboration services revenues are reduced by the 3% royalty we are required to pay Royalty Pharma on the net sales by Ipsen and Takeda of any products containing cabozantinib. The royalty payments due to Royalty Pharma increased in the three and six months ended June 30, 2025, as compared to the corresponding prior year periods, as a result of an increase in the royalty generating sales of cabozantinib by Ipsen and Takeda.

We project our collaboration services revenues may decrease for the remainder of 2025, as compared to the corresponding prior year period, primarily as a result of a decrease in development cost reimbursements and an increase in royalty payments to Royalty Pharma on net sales by Ipsen and Takeda of any products containing cabozantinib.

Cost of Goods Sold

The cost of goods sold and our gross margins were as follows (dollars in thousands):

			Three Months Ended June 30,												Percent Change						Six Months Ended June 30,												Percent Change
			2025						2024												2025						2024
Cost of goods sold			$	19,470					$	17,667					10		%				$	38,642					$	38,923					-1		%
Gross margin %			96		%				96		%										96		%				95		%

Cost of goods sold is related to our product revenues and consists of a 3% royalty payable on U.S. net sales of any product containing cabozantinib, as well as the cost of inventory sold, indirect labor costs, write-downs related to expiring, excess and obsolete inventory and other third-party logistics costs. The increase in cost of goods sold for the three months ended June 30, 2025, as compared to the corresponding prior year period, was primarily due to an increase in royalties as a result of increased U.S. CABOMETYX sales, partially offset by a decrease in certain period costs. The decrease in cost of goods sold for the six months ended June 30, 2025, as compared to the corresponding prior year period, was primarily due to a decrease in certain period costs, including a decrease in write-downs for excess inventory, partially offset by an increase in royalties as a result of increased U.S. CABOMETYX sales. We project our gross margin will not change significantly during the remainder of 2025.

Research and Development Expenses

We do not track fully burdened research and development expenses on a project-by-project basis. We group our research and development expenses into three categories: (a) development; (b) drug discovery; and (c) other research and development. Our development group leads the development and implementation of our clinical and regulatory strategies and prioritizes disease indications in which our compounds are being or may be studied in clinical trials.

Development expenses include license and other collaboration costs, primarily composed of upfront license fees, development milestones and other payments associated with our clinical-stage in-licensing collaboration programs, clinical trial costs, personnel expenses, consulting and outside services and other development costs, including manufacturing costs of our drug development candidates. Our drug discovery group utilizes a variety of technologies, including in-licensed technologies, to enable the rapid discovery, optimization and extensive characterization of lead compounds and biotherapeutics such that we are able to select development candidates with the best potential for further evaluation and advancement into clinical development. Drug discovery expenses include license and other collaboration costs primarily

31

Table of Contents

composed of upfront license fees, research funding commitments, option exercise fees, development milestones and other payments associated with our in-licensing collaboration programs in preclinical development stage. Other drug discovery costs include personnel expenses, consulting and outside services and laboratory supplies. Other research and development expenses include the allocation of general corporate costs to research and development services and development cost reimbursements in connection with certain of our collaboration arrangements.

Research and development expenses by category were as follows (dollars in thousands):

			Three Months Ended June 30,												Percent Change						Six Months Ended June 30,												Percent Change
			2025						2024												2025						2024

Stock-based compensation			14,143						9,178						54		%				23,665						13,070						81		%
Other research and development			30,697						30,639						0		%				61,938						59,059						5		%
Total research and development expenses			$	200,356					$	211,147					-5		%				$	412,589					$	438,836					-6		%

In addition, we track our external clinical trial costs by product and product candidate and by scientific modalities, which are categorized as small molecule and biotherapeutics programs. Small molecule clinical development for the reported periods were primarily composed of cabozantinib and zanzalintinib. Biotherapeutics clinical development for the reported periods were primarily composed of XB010, XB002 and XB628.

Clinical trial costs by scientific modalities, by product and by product candidate were as follows (dollars in thousands):

			Three Months Ended June 30,												Percent Change						Six Months Ended June 30,												Percent Change
			2025						2024												2025						2024
Small molecules:
Zanzalintinib			$	38,627					$	31,093					24		%				$	79,747					$	71,101					12		%
Cabozantinib			8,469						16,399						-48		%				18,452						34,725						-47		%
Other small molecules			4,607						3,490						32		%				10,123						7,579						34		%
Total small molecules			51,703						50,982						1		%				108,322						113,405						-4		%
Biotherapeutics			4,041						8,233						-51		%				10,163						20,528						-50		%
Total clinical trial costs			$	55,744					$	59,215					-6		%				$	118,485					$	133,933					-12		%

The decreases in research and development expenses for the three and six months ended June 30, 2025, as compared to the corresponding prior year periods, were primarily related to decreases in manufacturing costs to support our development candidates (presented as part of other development costs), license and other collaboration costs, and clinical trial costs, partially offset by increases in stock-based compensation, personnel expenses, and consulting and outside services.

Development-related license and other collaboration costs increased for three months ended June 30, 2025, as compared to the corresponding prior year period, primarily due to higher development milestone achievement in our clinical-stage in-licensing collaboration programs. Development-related license and other collaboration costs decreased for

32

Table of Contents

the six months ended June 30, 2025, as compared to the corresponding prior year period, primarily due to lower development milestones achievement in our clinical-stage in-licensing collaboration programs.

Drug discovery-related license and other collaboration costs decreased for the three and six months ended June 30, 2025, as compared to the corresponding prior year periods, primarily due to lower development milestone achievement in our discovery-stage in-licensing collaboration programs and lower research funding.

Clinical trial costs decreased for the three and six months ended June 30, 2025, as compared to the corresponding prior year periods, primarily due to lower costs associated with studies evaluating cabozantinib and XB002, partially offset by higher costs associated with zanzalintinib, XB010 and XL495 studies.

In addition to reviewing the three categories of research and development expenses described above, we principally consider qualitative factors in making decisions regarding our research and development programs. These factors include enrollment in clinical trials for our product candidates, preliminary data and final results from clinical trials, the potential market indications and overall clinical and commercial potential for our product candidates, and competitive dynamics. We also make our research and development decisions in the context of our overall business strategy.

We project that clinical trial costs may increase for the remainder of 2025, as compared to the corresponding prior year period, primarily driven by higher costs associated with various studies evaluating zanzalintinib, and the XL309, XB371, XB628 and XB010 studies, partially offset by lower costs associated with studies evaluating cabozantinib and XB002.

To continue growing our pipeline, we are prioritizing investment in new molecules that are clinically differentiated with the potential to improve the standard of care for our cancer patients, including current and planned clinical trial programs evaluating zanzalintinib, XL309, XB010, XB371, and XB628. We are working to expand our oncology product pipeline through drug discovery efforts, which encompass our diverse biotherapeutics and small molecule programs exploring multiple modalities and mechanisms of action. This approach provides a high degree of flexibility with respect to target selection and allows us to prioritize those targets that we believe have the greatest chance of yielding impactful therapeutics. As part of our strategy, our drug discovery activities have included and continue to include internal research, as well as external research collaborations, in-licensing arrangements and other strategic transactions that collectively incorporate a wide range of technology platforms and assets and increase our probability of success. As of the date of this Quarterly Report on Form 10-Q, we expect to progress up to two new development candidates into preclinical development later in 2025. We will continue to engage in pipeline expansion initiatives with the goal of acquiring and in-licensing promising investigational oncology assets and then further characterize and develop them utilizing our established preclinical and clinical development infrastructure.

We project our research and development expenses may increase for the remainder of 2025, as compared to the prior year period, primarily driven by increases in consulting and outside services, clinical trial costs, including the current and planned trials evaluating zanzalintinib, XL309, XB371, XB628 and XB010, and stock-based compensation.

Selling, general and administrative expenses were as follows (dollars in thousands):

			Three Months Ended June 30,												Percent Change						Six Months Ended June 30,												Percent Change

__________________

(1) Excludes stock-based compensation allocated to selling, general and administrative expenses.

Selling, general and administrative expenses consist primarily of personnel expenses, stock-based compensation, marketing costs and certain other administrative costs.

The increases in selling, general and administrative expenses for the three and six months ended June 30, 2025, as compared to the corresponding prior year periods, were primarily due to increases in personnel expenses, marketing

activities in support of the commercial launch of CABOMETYX for the treatment of patients with previously treated advanced NET, and stock-based compensation, partially offset by a decrease in corporate giving.

We project our selling, general and administrative expenses may increase for the remainder of 2025, as compared to the corresponding prior year period, primarily driven by an increase in stock-based compensation and personnel expenses.

Restructuring Expenses

There were no restructuring expenses for the three and six months ended June 30, 2025. Restructuring expenses for the three and six months ended June 30, 2024 were the result of a corporate restructuring plan announced and implemented in the first quarter of 2024 to reduce our workforce and rebalance our cost structure in alignment with our strategic priorities. Restructuring expenses consisted of severance and employee-related costs, asset impairment, and contract termination costs and were mostly incurred in the first quarter of 2024. The restructuring plan was substantially complete as of the end of the second quarter of 2024.

Restructuring expenses were as follows (dollars in thousands):

			Three Months Ended June 30,												Percent Change						Six Months Ended June 30,												Percent Change
			2025						2024												2025						2024
Restructuring			$	—					$	475					-100		%				$	—					$	33,310					-100		%

Non-Operating Income

Non-operating income was as follows (dollars in thousands):

			Three Months Ended June 30,												Percent Change						Six Months Ended June 30,												Percent Change
			2025						2024												2025						2024
Interest income			$	16,789					$	17,258					-3		%				$	35,865					$	37,152					-3		%
Other income (expenses), net			50						(287)						n/a						(195)						(376)						-48		%
Non-operating income			$	16,839					$	16,971					-1		%				$	35,670					$	36,776					-3		%

The decreases in non-operating income for the three and six months ended June 30, 2025, as compared to the corresponding prior year periods, were primarily the result of a decrease in interest income due to lower average interest-bearing investment balances, and lower average interest rates.

Provision for Income Taxes

The provision for income taxes and the effective tax rates were as follows (dollars in thousands):

			Three Months Ended June 30,												Percent Change						Six Months Ended June 30,												Percent Change
			2025						2024												2025						2024
Provision for income taxes			$	45,567					$	66,729					-32		%				$	91,641					$	78,679					16		%
Effective tax rate			19.8		%				22.8		%										21.0		%				23.0		%

The effective tax rate for the three months ended June 30, 2025, differed from the U.S. federal statutory rate of 21%, primarily due to excess tax benefits related to certain stock grants and the generation of federal tax credits, partially offset by state taxes. The effective tax rate for the six months ended June 30, 2025, differed from the U.S. federal statutory rate of 21%, primarily due to state taxes, offset by excess tax benefits related to certain stock grants and the generation of federal tax credits. The effective tax rate for the three and six months ended June 30, 2024, differed from the U.S. federal statutory tax rate of 21%, primarily due to state taxes, offset by the generation of federal tax credits.

Liquidity and Capital Resources

As of June 30, 2025, we had $1.4 billion in cash, cash equivalents and marketable securities, as compared to $1.7 billion as of December 31, 2024. We anticipate that the aggregate of our current cash, cash equivalents and

34

Table of Contents

marketable securities available for operations, net product revenues and collaboration revenues will enable us to maintain our operations for at least 12 months and thereafter for the foreseeable future.

Our primary cash requirements for operating activities, which we project will decrease for the remainder of 2025, as compared to the corresponding period in 2024, are employee-related expenditures; payments related to our collaboration and development programs; income tax payments; royalty payments on our net product sales; cash payments for inventory; rent payments for our leased facilities; and contract manufacturing payments.

The Tax Cuts and Jobs Act, signed into law on December 22, 2017, modified the tax treatment of research and experimental (R&E) expenditures beginning in fiscal year 2022, requiring that they must be capitalized and amortized ratably over five years for domestic R&E expenditures or 15 years for foreign R&E expenditures. The One Big Beautiful Bill Act was signed into law on July 4, 2025 which, among other provisions, permanently repeals the requirement to capitalize domestic R&E expenditures for federal income tax purposes for taxable years beginning after December 31, 2024, and allows for the accelerated deduction of any remaining unamortized domestic R&E expenditures. Foreign R&E expenditures are still required to be capitalized and amortized ratably over 15 years. The federal cash tax benefit for previously unamortized domestic R&E expenditures is estimated at $147 million with no corresponding impact to the federal income tax provision.

Our primary sources of operating cash are: cash collections from customers related to net product revenues, which we project may increase for the remainder of 2025, as compared to the corresponding period in 2024; cash collections related to milestones achieved and royalties earned from our commercial collaboration arrangements with Ipsen, Takeda and others; and cash collections for cost reimbursements under certain of our development programs with Ipsen and Takeda which we project may decrease for the remainder of 2025, as compared to the corresponding period in 2024. The timing of cash generated from commercial collaborations and cash payments required for in-licensing collaborations relative to upfront license fee payments, cost reimbursements, exercise of option payments and other contingent payments such as development milestone payments may vary from period to period.

We project that we may continue to spend significant amounts of cash to fund the development of product candidates in our pipeline, including zanzalintinib, XL309, XB371, XB628 and XB010, and the development and commercialization of cabozantinib. In addition, we may continue to expand our oncology product pipeline through additional research collaborations, in-licensing arrangements and other strategic transactions that align with our oncology drug development, regulatory and commercial expertise.

In August 2024, our Board of Directors authorized a stock repurchase program to acquire up to $500.0 million of our outstanding common stock before December 31, 2025. In February 2025, our Board of Directors authorized the repurchase of up to an additional $500.0 million of our outstanding common stock before December 31, 2025. Under these programs, as of June 30, 2025, we repurchased 21.7 million shares of common stock for an aggregate purchase price of $796.3 million. As of June 30, 2025, approximately $203.7 million remained available for future stock repurchases before December 31, 2025. Stock repurchases under these programs may be made from time to time through a variety of methods, which may include open market purchases, in block trades, Rule 10b5-1 trading plans, accelerated share repurchase transactions, exchange transactions, or any combination of such methods. The timing and amount of any stock repurchases under the stock repurchase programs will be based on a variety of factors, including ongoing assessments of the capital needs of the business, alternative investment opportunities, the market price of our common stock and general market conditions.

Financing these activities could materially impact our liquidity and capital resources and may require us to incur debt or raise additional funds through the issuance of equity. Furthermore, even though we believe we have sufficient funds for our current and future operating plans, we may choose to incur debt or raise additional funds through the issuance of equity based on market conditions or strategic considerations.

Sources and Uses of Cash (dollars in thousands):

			June 30, 2025						December 31, 2024						Percent Change
Working capital			$	844,653					$	1,063,810					-21		%

Working Capital: The decrease in working capital as of June 30, 2025, as compared to December 31, 2024, was

35

Table of Contents

primarily due to repurchases of our common stock, partially offset by the favorable impact to our net current assets resulting from our increase in net product revenues. In the future, our working capital may be impacted by one of these factors or other factors, the amounts and timing of which are variable.

Cash, Cash Equivalents and Marketable Securities: Cash and cash equivalents primarily consist of deposits at major banks, money market funds, commercial paper and other securities with original maturities 90 days or less. Marketable securities primarily consist of debt securities available-for-sale and certificates of deposit. For additional information regarding our cash, cash equivalents and marketable securities, see “Note 5. Cash and Marketable Securities” of the “Notes to Condensed Consolidated Financial Statements” included in Part I, Item 1 of this Quarterly Report on Form 10-Q. The decrease in cash, cash equivalents and marketable securities as of June 30, 2025, as compared to December 31, 2024, was primarily due to cash payments to repurchase our common stock, payments to support our development and discovery programs and cash payments for employee-related expenditures, partially offset by cash inflows generated by our operations from sales of our products and our commercial collaboration arrangements.

Cash flow activities were as follows (dollars in thousands):

			Six Months Ended June 30,												Percent Change
			2025						2024
Net cash provided by operating activities			$	260,430					$	188,370					38		%
Net cash provided by investing activities			$	297,795					$	193,565					54		%
Net cash used in financing activities			$	(611,166)					$	(446,470)					37		%

Operating Activities

Cash provided by operating activities is derived by adjusting our net income for non-cash operating items such as deferred taxes, stock-based compensation, depreciation and amortization, non-cash lease expense, impairment of long-lived assets, acquired in-process research and development technology, and changes in operating assets and liabilities, which reflect timing differences between the receipt and payment of cash associated with transactions and when they are recognized in our Condensed Consolidated Statements of Income.

Net cash provided by operating activities increased for the six months ended June 30, 2025, as compared to the corresponding prior year period, primarily due to an increase in cash received on sales of our products and a decrease in cash paid for certain operating expenses.

Investing Activities

The changes in cash flows from investing activities primarily relates to the timing of marketable securities investment activity, acquisition of in-process research and development technology and capital expenditures. Our capital expenditures primarily consist of marketable securities to expand our operations and acquire assets that further support our research and development activities.

Net cash provided by investing activities increased for the six months ended June 30, 2025, as compared to the corresponding prior year period. The increase in cash provided by investing activities was primarily due to an increase in cash proceeds from maturities and sales of marketable securities and decreases in purchases of property and equipment and other, and purchases of in-process research and development technology related to certain in-licensing collaboration arrangements, partially offset by an increase in purchases of marketable securities.

Financing Activities

The changes in cash flows from financing activities primarily relate to payments for repurchases of common stock, proceeds from employee stock programs and taxes paid related to net share settlement of equity awards.

Net cash used in financing activities increased for the six months ended June 30, 2025, as compared to the corresponding prior year period, primarily due to an increase in payments for repurchases of common stock and higher withholding taxes remitted to the government related to net share settlements of equity awards, partially offset by an increase in proceeds received from the issuance of common stock under our equity incentive plans.

Contractual Obligations

There were no material changes outside of the ordinary course of business in our contractual obligations as of June 30, 2025 from those disclosed in our Fiscal 2024 Form 10-K. For more information about our leases and our other contractual obligations, see “Note 12. Commitments and Contingencies” of the “Notes to Consolidated Financial Statements” included in Part II, Item 8 of our Fiscal 2024 Form 10-K.

Critical Accounting Policies and Estimates

The preparation of our Condensed Consolidated Financial Statements conforms to accounting principles generally accepted in the U.S. which requires management to make judgments, estimates and assumptions that affect the reported amounts of assets, liabilities, equity, revenues and expenses and related disclosures. An accounting policy is considered to be critical if it requires an accounting estimate to be made based on assumptions about matters that are highly uncertain at the time the estimate is made, and if different estimates that reasonably could have been used, or changes in the accounting estimates that are reasonably likely to occur periodically, could materially impact our Condensed Consolidated Financial Statements. On an ongoing basis, management evaluates its estimates, including, but not limited to: those related to revenue recognition, including determining the nature and timing of satisfaction of performance obligations, and determining the standalone selling price of performance obligations, and variable consideration such as rebates, chargebacks, sales returns and sales allowances as well as milestones included in collaboration arrangements; the accrual for certain liabilities, including accrued clinical trial liabilities; and valuations of equity awards used to determine stock-based compensation, including certain awards with vesting subject to market or performance conditions; and the amounts of deferred tax assets and liabilities, including the related valuation allowance. We base our estimates on historical experience and on various other market-specific and other relevant assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Our senior management has discussed the development, selection and disclosure of these estimates with the Audit Committee of our Board of Directors. Actual results could differ materially from those estimates.

We believe our critical accounting policies relating to revenue recognition, clinical trial and collaboration accruals, stock-based compensation and income taxes reflect the more significant estimates and assumptions used in the preparation of our Condensed Consolidated Financial Statements.

There have been no significant changes in our critical accounting policies and estimates during the six months ended June 30, 2025, as compared to the critical accounting policies and estimates disclosed in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” included in Part II, Item 7 of our Fiscal 2024 Form 10-K.

Item 4. Controls and Procedures.

Evaluation of Disclosure Controls and Procedures

Based on the evaluation of our disclosure controls and procedures (as defined in Rules 13a-15(e) or 15d-15(e) of the Securities Exchange Act of 1934, as amended (the Exchange Act)) required by Rules 13a-15(b) or 15d-15(b) of the Exchange Act, our Chief Executive Officer and Chief Financial Officer have concluded that as of the end of the period covered by this report, our disclosure controls and procedures were effective at the reasonable assurance level.

Table of Contents

Limitations on the Effectiveness of Controls

A control system, no matter how well-conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Because of inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues, if any, within an organization have been detected. Accordingly, our disclosure controls and procedures are designed to provide reasonable, not absolute, assurance that the objectives of our disclosure control system are met and, as set forth above, our principal executive officer and principal financial officer have concluded, based on their evaluation as of the end of the period covered by this report, that our disclosure controls and procedures were effective to provide reasonable assurance that the objectives of our disclosure control system were met.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting that occurred during our most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds.

In August 2024, our Board of Directors authorized a stock repurchase program to acquire up to $500.0 million of our outstanding common stock before December 31, 2025. In February 2025, our Board of Directors authorized the repurchase of up to an additional $500.0 million of our outstanding common stock before December 31, 2025. Under these programs, as of June 30, 2025, we repurchased 21.7 million shares of common stock for an aggregate purchase price of $796.3 million. As of June 30, 2025, approximately $203.7 million remained available for future stock repurchases before December 31, 2025.

The following table summarizes the stock repurchase activity for the three months ended June 30, 2025 and the approximate dollar value of shares that may yet be purchased pursuant to our stock repurchase programs (in thousands, except per share data):

			Total Number of Shares Purchased						Average Price Paid per Share						Total Number of Shares Purchased as Part of Publicly Announced Programs						Approximate Dollar Value of Shares That May Yet Be Purchased Under the Programs
April 5, 2025 - May 2, 2025			2,605						$	36.46					2,605						$	410,568

Total			7,527												7,527

Stock repurchases under these programs may be made from time to time through a variety of methods, which may include open market purchases, in block trades, Rule 10b5-1 trading plans, accelerated share repurchase transactions, exchange transactions, or any combination of such methods. The timing and amount of any stock repurchases under the stock repurchase programs will be based on a variety of factors, including ongoing assessments of the capital needs of the business, alternative investment opportunities, the market price of our common stock and general market conditions. The programs do not obligate us to acquire any amount of our common stock, and the stock repurchase programs may be modified, suspended or discontinued at any time without prior notice.
