 EXPLANATORY NOTE
 This Amendment No. 1 to Form 10-K (this "Amendment") amends the Annual Report on Form 10-K for the fiscal year ended December 31, 2023, originally filed on February 13, 2024 (the "Original Form 10-K") of Incyte Corporation (the "Company," "we" or "our"). We are filing this Amendment solely to correct an administrative error that resulted in an incorrect document being filed with the Original Form 10-K as Exhibit 97.1, Incyte Corporation Policy for Recoupment of Erroneously Awarded Compensation. The correct document is filed as Exhibit 97.1 attached hereto.
 This Amendment speaks as of the filing date of the Original Form 10-K and does not reflect events occurring after the filing of the Original Form 10-K. No revisions are being made to the Company's financial statements or any other disclosure contained in the Original Form 10-K. This Amendment is an exhibit-only filing. Except for Exhibit 97.1, this Amendment does not otherwise update any exhibits as originally filed or previously amended.
 In addition, as required by Rule 12b-15 under the Securities Exchange Act of 1934 (the "Exchange Act"), we are filing as exhibits to this Amendment new certifications by our principal executive officer and principal financial officer under Section 302 of the Sarbanes-Oxley Act of 2002, pursuant to Rule 13a-14(a) or 15d-14(a) of the Exchange Act. As no financial statements or financial information has been included in this Amendment and this Amendment does not contain or amend disclosure pursuant to Item 307 or 308 of Regulation S-K, paragraphs 3, 4 and 5 of those certifications have been omitted. We are also not including certifications under Section 1350 of Chapter 63 of Title 18 of the United States Code (18 U.S.C. 1350) (Section 906 of the Sarbanes-Oxley Act of 2002) as this Amendment includes no financial statements.
