CG Oncology, Inc.

We have adopted a Code of Conduct and Ethics, which is applicable to all of our directors, officers and employees, including our Chief Executive Officer, Chief Financial Officer, Controller and other senior financial officers. The Code of Conduct and Ethics provides a framework for sound ethical business decisions and sets forth our expectations on a number of topics, including conflicts of interest, compliance with laws, use of our assets and business ethics. Our Code of Conduct and Ethics is posted in the “Corporate Governance” section of our website located at www.ir.cgoncology.com. If the Company ever were to amend or waive any provision of its Code of Conduct and Ethics that applies to the Company’s principal executive officer, principal financial officer, principal accounting officer or any person performing similar functions, the Company intends to satisfy its disclosure obligations, if any, with respect to any such waiver or amendment by posting such information on its website set forth above rather than by filing a Current Report on Form 8-K. In the case of a waiver for an executive officer or a director, the disclosure required under applicable Nasdaq listing standards also will be made available on our website.
