Organization, Consolidation and Presentation of Financial Statements [Abstract]
ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Organization Exelixis, Inc. (Exelixis, we, our or us) is an oncology-focused biotechnology company that strives to accelerate the discovery, development and commercialization of new medicines for patients with difficult-to-treat cancers. Using our considerable drug discovery, development and commercialization resources and capabilities, we have invented and brought to market innovative therapies that appropriately balance patient benefits and risks; we will continue to build on this foundation as we strive to provide cancer patients with new treatment options that improve upon current standards of care. Today, four products that originated in Exelixis laboratories are available to be prescribed to patients. Sales related to our flagship molecule, cabozantinib, account for the large 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 62 other countries as: CABOMETYX® (cabozantinib) tablets approved for advanced renal cell carcinoma (RCC), both alone and in combination with Bristol-Myers Squibb Company’s (BMS) OPDIVO® (nivolumab), for previously treated hepatocellular carcinoma (HCC) and, currently by the FDA and European Commission (EC), for previously treated, radioactive iodine (RAI)-refractory differentiated thyroid cancer (DTC); and COMETRIQ® (cabozantinib) capsules approved for progressive, metastatic medullary thyroid cancer (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 (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 (Daiichi Sankyo). Basis of Presentation The accompanying 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. The accompanying unaudited 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 nine months ended September 30, 2022 are not necessarily indicative of the results that may be expected for the year ending December 31, 2022 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 included in Part II, Item 8 of our Annual Report on Form 10-K for the fiscal year ended December 31, 2021, filed with the SEC on February 18, 2022 (Fiscal 2021 Form 10-K). We have adopted a 52- or 53-week fiscal year policy that generally ends on the Friday closest to December 31st. Fiscal year 2022, which is a 52-week fiscal year, will end on December 30, 2022 and fiscal year 2021, which was a 52-week fiscal year, ended on December 31, 2021. For convenience, references in this report as of and for the fiscal period ended October 1, 2021, and as of and for the fiscal year ending December 30, 2022 are indicated as being as of and for the period ended September 30, 2021, and the year ending December 31, 2022, respectively. Segment Information We operate in one business segment that focuses on the discovery, development and commercialization of new medicines for difficult-to-treat cancers. Our 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 Chief Executive Officer uses consolidated, single-segment financial information for purposes of evaluating performance, forecasting future period financial results, allocating resources and setting incentive targets. All of our long-lived assets are located in the U.S. See “Note 2. Revenues” for enterprise-wide disclosures about product sales, revenues from major customers and revenues by geographic region. 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 nine months ended September 30, 2022, 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 2021 Form 10-K. Recently Adopted Accounting Pronouncements There were no new accounting pronouncements adopted by us since the filing of our Fiscal 2021 Form 10-K, which could have a significant effect on our Condensed Consolidated Financial Statements. Recent Accounting Pronouncements Not Yet Adopted There were no new accounting pronouncements issued since the filing of our Fiscal 2021 Form 10-K, which could have a significant effect on our Condensed Consolidated Financial Statements.

Collaboration Agreements And Business Development Activities

9 Months Ended

Sep. 30, 2022

Organization, Consolidation and Presentation of Financial Statements [Abstract]

COLLABORATION AGREEMENTS AND BUSINESS DEVELOPMENT ACTIVITIES

We have established multiple collaborations with leading pharmaceutical companies for the commercialization and further development of our cabozantinib franchise. Additionally, we have entered into several research collaborations, in-licensing arrangements and other strategic transactions 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 and their physicians. Historically, we also entered into other collaborations with leading pharmaceutical companies pursuant to which we out-licensed other compounds and programs in our portfolio.

See “Note 3. Collaboration Agreements and Business Development Activities” of the “Notes to Consolidated Financial Statements” included in Part II, Item 8 of our Fiscal 2021 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 agreement with Ipsen for the commercialization and further development of cabozantinib. Under the terms of 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):

During the nine months ended September 30, 2022, we recognized $25.8 million in revenues in connection with two regulatory milestones totaling $27.0 million upon approval by the European Commission and Health Canada, of cabozantinib as monotherapy for the treatment of adult patients with locally advanced or metastatic differentiated thyroid carcinoma (DTC), refractory or not eligible to RAI who have progressed during or after prior systemic therapy.

As of September 30, 2022, $49.3 million of the transaction price for this collaboration was allocated to our research and development services performance obligations that have not yet been satisfied.

Takeda Collaboration

In January 2017, we entered into a collaboration and license agreement with Takeda for the commercialization and further development of cabozantinib. Pursuant to this collaboration and license agreement, as amended, Takeda has 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.

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


	Three Months Ended September 30,				Nine Months Ended September 30,
	2022		2021		2022		2021
License revenues	$	2,690	$	20,078	$	7,755	$	23,476

Total	$	6,351	$	22,734	$	18,903	$	34,291

As of September 30, 2022, $33.8 million of the transaction price for this collaboration was allocated to our research and development services performance obligations that have not yet been satisfied.

Royalty Pharma

In October 2002, we established a product development and commercialization collaboration agreement with GlaxoSmithKline (GSK), that required us to pay a 3% royalty to GSK on the worldwide net sales of any product incorporating 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 U.S. market through September 2026, after which time U.S. royalties will revert back to GSK. Royalties earned by Royalty Pharma in connection with our sales of cabozantinib are included in cost of goods sold and in connection with sales by our collaboration partners are included as a reduction of collaboration services revenues. Such royalties were $14.9 million and $42.6 million during the three and nine months ended September 30, 2022, respectively, as compared to $11.5 million and $33.7 million for the corresponding prior year periods.

Other Commercial Collaborations

Genentech Collaboration

In December 2006, we out-licensed the development and commercialization of cobimetinib to Genentech under a worldwide collaboration agreement. In November 2015, the FDA approved cobimetinib, under the brand name COTELLIC, in combination with Genentech’s ZELBORAF® (vemurafenib) for the treatment of patients with BRAF V600E or V600K mutation-positive advanced melanoma. COTELLIC in combination with ZELBORAF has also been approved in the European Union and multiple additional countries for use in the same indication. In July 2020, the FDA also approved COTELLIC for use in combination with ZELBORAF and TECENTRIQ® (atezolizumab) for the treatment of patients with BRAF V600 mutation-positive advanced melanoma in previously untreated patients.

License revenues under the collaboration agreement with Genentech were as follows (in thousands):


	Three Months Ended September 30,				Nine Months Ended September 30,

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

Our research collaborations, in-licensing arrangements and other strategic transactions include upfront payments, which are generally paid upon the closing of the transaction, and also milestone payments (in connection with development, regulatory or commercial achievements) and royalty payments, which are contingent upon the occurrence of certain future events linked to the success of the asset in development. Certain of our research collaborations and in-licensing arrangements provide us exclusive options that give us the right to license programs developed under the research collaborations for further discovery and development. When we decide to exercise an option, we are required to pay an exercise fee and then, in most instances, we will assume the responsibilities for all subsequent clinical development, manufacturing and commercialization of the licensed asset.

In June 2022, we entered into an exclusive option and license agreement with BioInvent International AB (BioInvent), upon which we paid an upfront payment of $25.0 million. Upon option exercise, we will pay BioInvent an option exercise fee, and BioInvent will be eligible for additional payments from us for future development and commercial milestones, as well as royalties on our future net product sales. In July 2022, we entered into an exclusive license agreement with Ryvu Therapeutics S.A. (Ryvu) and paid an upfront payment of $3.0 million. Ryvu is eligible for potential future development and commercial milestones as well as royalties on future net product sales.

As of September 30, 2022, in conjunction with each of our research collaborations and in-licensing arrangements, and an asset purchase agreement entered into in 2021, we are subject to contingent payments for potential future development milestones of up to $364.7 million, regulatory milestones of up to $453.4 million and commercial milestones of up to $2,443.4 million, each in the aggregate per product or target, as well as royalties on future net product sales.

Cash, cash equivalents, and restricted cash equivalents as reported in the accompanying Condensed Consolidated Statements of Cash Flows	$	676,768	$	663,891

Restricted cash equivalents are used to collateralize letters of credit and consist of money-market funds and certificates of deposit with original maturities of 90 days or less. The restricted cash equivalents are classified as other long-term assets based upon the remaining term of the underlying restriction. The standby letter of credit entered in January 2021, as a guarantee of our obligation to fund our portion of the tenant improvements related to our Alameda build-to-suit lease was terminated and the related collateral was returned in the third quarter of 2022, following the substantial completion of the building and the commencement of the lease.

Realized gains and losses on the sales of investments were insignificant during the three and nine months ended September 30, 2022 and 2021.

We manage credit risk associated with our investment portfolio through our investment policy, which limits purchases to high-quality issuers and limits the amount of our portfolio that can be invested in a single issuer. The fair value and gross unrealized losses on debt securities available-for-sale in an unrealized loss position were as follows (in thousands):

There were 276 and 133 investments in an unrealized loss position as of September 30, 2022 and December 31, 2021, respectively. All securities presented above have been in an unrealized loss position for less than twelve months except for 25 corporate bond securities and 1 municipal bond security with an aggregate fair value of $64.0 million and an aggregate $2.4 million unrealized loss as of September 30, 2022. During the nine months ended September 30, 2022 and 2021, we did not record an allowance for credit losses or other impairment charges on our investment 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 investments, we determined that it was more likely than not that we will hold these investments for a period of time sufficient for a recovery of our cost basis.

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

Fair Value Measurements

Fair Value Disclosures [Abstract]

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.

The classifications within the fair value hierarchy of our financial assets that were measured and recorded at fair value on a recurring basis were as follows (in thousands):


	September 30, 2022
	Level 1		Level 2		Total
Commercial paper	$	—	$	873,856	$	873,856
Corporate bonds	—		618,122		618,122

Money market funds	66,531		—		66,531

Total financial assets carried at fair value	$	66,531	$	1,652,724	$	1,719,255

When available, we value investments based on quoted prices for those financial instruments, which is a Level 1 input. Our remaining investments 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 cash, receivables and payables, approximate their fair values due to their short-term nature.

Forward Foreign Currency Contracts

We have entered into forward contracts to hedge certain operational exposures for the changes in foreign currency exchanges rates associated with assets or liabilities denominated in foreign currencies, primarily the Euro.

As of September 30, 2022, we had one forward contract outstanding to sell €10.0 million. The forward contract with a maturity of three months is recorded at fair value and is included in prepaid expenses and other current assets in the Condensed Consolidated Balance Sheets. The unrealized loss on the forward contract is not material as of September 30, 2022. The forward contract is considered a Level 2 in the fair value hierarchy of our fair value measurements. For the nine months period ended September 30, 2022, and 2021, we recognized $1.5 million and $0.5 million, respectively, of net gains on the maturity of our forward contracts, which is included in other income (expense), net on our Condensed Consolidated Statements of Income.

On May 25, 2022, at the 2022 Annual Meeting of Stockholders, our stockholders approved the amendment and restatement of Exelixis, Inc. 2017 Equity Incentive Plan (as amended and restated, the 2017 Plan). The amendment and restatement increased the share reserve under the 2017 Plan by 28,500,000 shares. As of September 30, 2022, 31,485,656 shares were available for grant under 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 restricted stock units (RSUs).

During the nine months ended September 30, 2022, we granted 588,862 stock options with a weighted average exercise price of $19.99 per share and a weighted average grant date fair value of $8.36 per share. As of September 30, 2022, there were 11,416,151 stock options outstanding and $19.6 million of related unrecognized compensation expense.

In March 2022, we awarded to certain employees an aggregate of 1,003,482 (the target amount) RSUs that are subject to a total shareholder return (TSR) market condition (the 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 1, 2022 through January 3, 2025. Depending on the results relative to the TSR market condition, the holders of the TSR-based RSUs may earn up to 175% of the target amount of shares. 50% of the shares earned pursuant to the TSR-based RSU awards will vest at the end of the performance period, and the remainder will vest approximately one year later, subject to employee’s continuous service. These TSR-based RSUs will be forfeited if the market condition at or above a threshold level is not achieved at the end of the performance period on January 3, 2025.

We used a Monte Carlo simulation model and the following assumptions to determine the grant date fair value of $33.17 per share for the TSR-based RSUs:


Fair value of the Company’s common stock on grant date	$	20.70
Expected volatility	46.85		%
Risk-free interest rate	1.59		%
Dividend yield	—		%

The Monte Carlo simulation model also assumed correlations of returns of the stock prices of the Company’s 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 total stockholder return based on the provisions of the award.

During the nine months ended September 30, 2022, we granted 5,292,088 service-based RSUs with a weighted average grant date fair value of $20.56 per share. As of September 30, 2022, there were 11,864,173 RSUs outstanding, including the TSR-based RSUs, and $193.8 million of related unrecognized compensation expense.

Stock options and service-based RSUs granted to employees during the nine months ended September 30, 2022 have vesting conditions and contractual lives of a similar nature to those described in “Note 8. Employee Benefit Plans” of the “Notes to Consolidated Financial Statements” included in Part II, Item 8 of our Fiscal 2021 Form 10-K.

As of September 30, 2022, there were 5,367,906 performance-based restricted stock units (PSUs) outstanding and $101.0 million of related unrecognized stock-based compensation expense. Expense recognition for PSUs commences when it is determined that achievement of the performance target is probable. During the three months ended September 30, 2022, we achieved a performance condition for threshold achievement for 495,886 PSUs granted during 2020 (the 2020 PSUs) and have recognized $9.7 million of stock-based compensation expense related to the 2020 PSUs during the three

months ended September 30, 2022. For more information about our PSUs, see “Note 8. Employee Benefit Plans” of the “Notes to Consolidated Financial Statements” included in Part II, Item 8 of our Fiscal 2021 Form 10-K.

Income Tax Disclosure [Abstract]
PROVISION FOR INCOME TAXES	PROVISION FOR INCOME TAXES The effective tax rates for the three and nine months ended September 30, 2022, were 20.5% and 20.1% respectively, as compared to 28.3% and 22.8% for the corresponding periods in 2021. The effective tax rates for the three and nine months ended September 30, 2022 differed from the U.S. federal statutory tax rate of 21% primarily due to excess tax benefits related to the exercise of certain stock options during the periods and the generation of federal tax credits, which were partially offset by state taxes. The effective tax rates for the three and nine months ended September 30, 2021 differed from the U.S. federal statutory tax rate of 21% primarily due to non-deductible executive compensation, which was partially offset by excess tax benefits related to the exercise of certain stock options during the periods and the generation of federal tax credits.

Dilutive securities included outstanding stock options, unvested RSUs, including TSR-based RSUs, PSUs and ESPP contributions.

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 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):

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES Build-to-Suit Lease and Headquarters Lease In April 2022, the office building (New Premises) associated with our October 2019 build-to-suit lease agreement (Build-to-Suit Lease) was substantially completed. The New Premises is 220,517 square feet and is in Alameda, California, adjacent to our existing corporate headquarters. The Build-to-Suit Lease term is 242 months, includes two five-year options to extend the term of the lease and a one-time option to terminate the lease after 180 months. In addition to the monthly lease payments, currently estimated at $0.7 million, subject to an annual increase of 3% during the Term, we are also responsible for paying operating expenses related to the New Premises. On April 15, 2022, the lease commenced for the New Premises. We determined the classification of the lease was an operating lease. Upon commencement of the lease, we recognized a right-of-use asset of $160.9 million inclusive of $44.9 million for the cost of the tenant improvements in excess of the allowance provided by the lessor and an operating lease liability of $116.0 million discounted over 180 months using our estimated incremental borrowing rate of 4.9%. In May 2022, we entered into the seventh amendment to the lease for our corporate headquarters located on Harbor Bay Parkway, Alameda, California (the Alameda Lease). The May 2022 amendment to the Alameda Lease (the Seventh Lease Amendment) provides, among other things, for the expansion of the premises under the Alameda Lease by 34,745 square feet of office facilities located at 1751 Harbor Bay Parkway, Alameda, California (the 1751 Expansion Space). The term for the 1751 Expansion Space will run coterminous with the term of the Alameda Lease for the existing space. In connection with the Seventh Lease Amendment, we remeasured our lease components under the Alameda Lease relating to the existing premises using an incremental borrowing rate of 5.0%. As of June 1, 2022, we have taken possession of the 1751 Expansion Space, and accordingly we have adjusted our right-of-use asset and liability by $4.3 million. For more information about our Leases, see “Note 11. Commitments and Contingencies—Leases” of the “Notes to Consolidated Financial Statements” included in Part II, Item 8 of our Fiscal 2021 Form 10-K. Legal Proceedings MSN I 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 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), 9,724,342 (formulations), 10,034,873 (methods of treatment) and 10,039,757 (methods of treatment), 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) or 8,497,284 (methods of treatment), 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 U.S. Patent No. 8,877,776 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 U.S. Patent No. 8,877,776 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. In particular, the May 5, 2020 amended ANDA requested approval to market a generic version of CABOMETYX tablets prior to expiration of two previously unasserted CABOMETYX patents: U.S. Patents No. 7,579,473 and 8,497,284. On May 11, 2020, we filed a complaint in the Delaware District Court for patent infringement against MSN asserting infringement of U.S. Patents No. 7,579,473 and 8,497,284 arising from MSN’s amended ANDA filing with the FDA. Neither of our complaints have alleged infringement of U.S. Patents No. 9,724,342, 10,034,873 and 10,039,757. On May 22, 2020, MSN filed its response to the complaint, alleging that the asserted claims of U.S. Patents No. 7,579,473 and 8,497,284 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) is invalid and would not be infringed by MSN if its generic version of CABOMETYX tablets were approved by the FDA. U.S. Patent No. 9,809,549 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 U.S. Patent No. 9,809,549 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. On October 1, 2021, 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 U.S. Patents No. 7,579,473 and 8,497,284, 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 ANDA product prior to the expiration of U.S. Patents No. 7,579,473 and 8,497,284 would also infringe certain claims of each patent, if those claims are not found to be invalid. Then, on October 12, 2021, pursuant to a separate stipulation between us and MSN, the Delaware District Court entered an order dismissing MSN’s counterclaims with respect to U.S. Patent No. 9,809,549. In our MSN I complaints, we are seeking, among other relief, an order that the effective date of any FDA approval of MSN’s ANDA be a date no earlier than the expiration of all of U.S. Patents No. 7,579,473, 8,497,284 and 8,877,776, the latest of which expires on October 8, 2030, and equitable relief enjoining MSN from infringing these patents. In an effort to streamline the case, the parties have narrowed their assertions. On April 8, 2022, MSN withdrew its validity challenge to U.S. Patent No. 8,877,776. On April 14, 2022, we agreed not to assert U.S. Patent No. 8,497,284 at trial and MSN has, correspondingly, agreed to withdraw its validity challenges to U.S. Patent No. 8,497,284, as well as claims 1-4 and 6-7 of U.S. Patent No. 7,579,473. As a result of this narrowing, the trial addressed two issues: (1) infringement of claim 1 of the U.S. Patent No. 8,877,776; and (2) validity of claim 5 of the U.S. Patent No. 7,579,473. A bench trial for MSN I occurred in May 2022, and a judgment is expected during the fourth quarter of 2022. MSN II ANDA Litigation 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), 11,091,440 (pharmaceutical composition) and 11,098,015 (methods of treatment). On February 23, 2022, we filed a complaint in the Delaware District Court for patent infringement against MSN asserting infringement of U.S. Patents No. 11,091,439, 11,091,440 and 11,098,015 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 U.S. Patents No. 11,091,439, 11,091,440 and 11,098,015 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). On July 18, 2022, we filed a complaint in the Delaware District Court for patent infringement against MSN asserting infringement of U.S. Patent No. 11,298,349 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 U.S. Patent No. 11,298,349 are invalid and not infringed. 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 U.S. Patents No. 11,091,439, 11,091,440 and 11,098,015, 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 ANDA product prior to the expiration of U.S. Patents No. 11,091,439, 11,091,440 and 11,098,015 would also infringe certain claims of each patent, if those claims are not found to be invalid. In our MSN II complaints, we are seeking, among other remedies, equitable relief enjoining MSN from infringing this patent, as well as an order that the effective date of any FDA approval of MSN’s ANDA would be a date no earlier than the expiration of all of U.S. Patents No. 11,091,439, 11,091,440, 11,098,015 and 11,298,349, the latest of which expires on February 10, 2032. A bench trial for MSN II has been scheduled for October 2023. Teva ANDA Litigation In May 2021, we received notice letters from Teva Pharmaceutical Industries Limited, Teva Pharmaceuticals Development, Inc. and Teva Pharmaceuticals USA, Inc. (individually and collectively referred to as Teva) regarding an ANDA Teva submitted to the FDA, requesting approval to market a generic version of CABOMETYX tablets. Teva’s notice letters included a Paragraph IV certification with respect to our U.S. Patents No. 9,724,342 (formulations), 10,034,873 (methods of treatment) and 10,039,757 (methods of treatment), which are listed in the Orange Book. Teva’s notice letters did not provide a Paragraph IV certification against any additional CABOMETYX patents. On June 17, 2021, we filed a complaint in the Delaware District Court for patent infringement against Teva asserting infringement of U.S. Patents No. 9,724,342, 10,034,873 and 10,039,757 arising from Teva’s ANDA filing with the FDA. On August 27, 2021, Teva filed its answer and counterclaims to the complaint, alleging that the asserted claims of U.S. Patents No. 9,724,342, 10,034,873 and 10,039,757 are invalid and not infringed. On September 17, 2021, we filed an answer to Teva’s counterclaims. On July 29, 2022, we received notice from Teva that it had amended its ANDA to assert an additional Paragraph IV certification. As amended, Teva’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). On September 2, 2022, we filed a complaint in the Delaware District Court for patent infringement against Teva, asserting infringement of U.S. Patent No. 11,298,349 arising from Teva’s amended ANDA filing with the FDA. We are seeking, among other relief, an order that the effective date of any FDA approval of Teva’s ANDA be a date no earlier than the expiration of all of U.S. Patents No. 9,724,342, 10,034,873, 10,039,757 and 11,298,349, the latest of which expires on July 9, 2033, and equitable relief enjoining Teva from infringing these patents. On September 30, 2022, the parties filed a stipulation to consolidate the two lawsuits, numbered Civil Action Nos. 21-00871 and 22-01168, and to stay all proceedings, which was granted by the Delaware District Court on October 3, 2022. Following a similar order granted by the Delaware District Court on February 9, 2022 to stay all proceedings with respect to Civil Action No. 21-00871, this case remained administratively closed, and Civil Action No. 22-01168 was administratively closed on October 3, 2022. The sale of any generic version of CABOMETYX earlier than its patent expiration 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. 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.

Organization and Summary of Significant Accounting Policies (Policies)	9 Months Ended
	Sep. 30, 2022
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Consolidation	The accompanying 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.
Basis of Presentation	The accompanying unaudited 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 nine months ended September 30, 2022 are not necessarily indicative of the results that may be expected for the year ending December 31, 2022 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 included in Part II, Item 8 of our Annual Report on Form 10-K for the fiscal year ended December 31, 2021, filed with the SEC on February 18, 2022 (Fiscal 2021 Form 10-K).
Fiscal Period	We have adopted a 52- or 53-week fiscal year policy that generally ends on the Friday closest to December 31st. Fiscal year 2022, which is a 52-week fiscal year, will end on December 30, 2022 and fiscal year 2021, which was a 52-week fiscal year, ended on December 31, 2021. For convenience, references in this report as of and for the fiscal period ended October 1, 2021, and as of and for the fiscal year ending December 30, 2022 are indicated as being as of and for the period ended September 30, 2021, and the year ending December 31, 2022, respectively.
Segment Information	We operate in one business segment that focuses on the discovery, development and commercialization of new medicines for difficult-to-treat cancers. Our 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 Chief Executive Officer uses consolidated, single-segment financial information for purposes of evaluating performance, forecasting future period financial results, allocating resources and setting incentive targets.
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.
Recently Adopted Accounting Pronouncements and Recent Accounting Pronouncements Not Yet Adopted	Recently Adopted Accounting Pronouncements There were no new accounting pronouncements adopted by us since the filing of our Fiscal 2021 Form 10-K, which could have a significant effect on our Condensed Consolidated Financial Statements. Recent Accounting Pronouncements Not Yet Adopted There were no new accounting pronouncements issued since the filing of our Fiscal 2021 Form 10-K, which could have a significant effect on our Condensed Consolidated Financial Statements.
Revenues	Total revenues include net product revenues attributed to geographic regions based on the ship-to location and license and collaboration services revenues attributed to geographic regions based on the location of our collaboration partners’ headquarters. Net product revenues and license revenues are recorded in accordance with ASC Topic 606, Revenue from Contracts with Customers (Topic 606). License revenues include the recognition of the portion of milestone payments allocated to the transfer of intellectual property licenses for which it had become probable in the current period that the milestone would be achieved and a significant reversal of revenues would not occur, as well as royalty revenues and our share of profits under our collaboration agreement with Genentech. Collaboration services revenues were recorded in accordance with ASU 2018-18, Collaborative Arrangements (Topic 808): Clarifying the Interaction between Topic 808 and Topic 606 and by analogy to Topic 606. Collaboration services revenues include the recognition of deferred revenues for the portion of upfront and milestone payments allocated to our research and development services performance obligations, development cost reimbursements earned under our collaboration agreements, product supply revenues, net of product supply costs, and the royalties we paid on sales of products containing cabozantinib by our collaboration partners. 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).
