| Amendment Description | UroGen Pharma Ltd. (the “Company,” “our,” “us” or “we”) is filing this Amendment No. 1 on Form 10‑K/A (this “Amendment No. 1”) to our Annual Report on Form 10-K for the fiscal year ended December 31, 2023 (the “Form 10-K”), which was filed with the U.S. Securities and Exchange Commission (the “SEC”) on March 14, 2024, to provide the information required by Part III of Form 10-K. This Amendment No. 1 amends and restates in their entirety Items 10, 11, 12, 13 and 14 of Part III of the Form 10-K. In addition, as required by Section 302 of the Sarbanes-Oxley Act of 2002 and Rule 12b-15 of the Securities Exchange Act of 1934 (the “Exchange Act”), as amended, updated certifications of the Company’s principal executive officer and principal financial officer are included as Exhibits 31.3 and 31.4 hereto. Because no financial statements have been included in this Amendment No. 1 and this Amendment No. 1 does not contain or amend any disclosure with respect to Items 307 and 308 of Regulation S-K, paragraphs 3, 4, and 5 of the certifications have been omitted. We are not including the certifications under Section 906 of the Sarbanes-Oxley Act of 2002 as no financial statements are being filed with this Amendment No. 1. This Amendment No. 1 also amends Item 15 of Part IV to add the foregoing certifications. No other changes have been made to the Form 10-K other than those described above. This Amendment No. 1 does not reflect subsequent events occurring after the original filing date of the Form 10-K or modify or update in any way the financial statements, consents or any other items or disclosures made in the Form 10-K in any way other than as required to reflect the amendments discussed above. Accordingly, this Amendment No. 1 should be read in conjunction with the Form 10-K and the Company’s other filings with the SEC subsequent to the filing of the Form 10-K. | ||
