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 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.
