On April 9, 2018, the staff (the “Staff”) of the Securities and Exchange Commission’s (the “SEC”) Division of Enforcement issued “Wells notices” to Clovis Oncology, Inc. (the “Company”) and certain of its current and former officers stating that the Staff has made a preliminary determination to recommend that the SEC file civil enforcement action(s) against the Company and such officers, alleging violations of certain provisions of the Securities Act of 1933 and the Securities Exchange Act of 1934 relating to the Company’s regulatory update announcement in November 2015 that the FDA requested additional clinical data on the efficacy and safety of rociletinib.

A Wells Notice is not a formal allegation or a finding of wrongdoing, but is a preliminary determination by the Staff to recommend to the SEC that a civil enforcement action or administrative proceeding be brought against the recipient. The Company has an opportunity to respond to issues raised by the SEC staff and offer its perspective prior to any SEC decision on whether to authorize the commencement of an enforcement proceeding. Under SEC procedures, a recipient of a Wells Notice has an opportunity to respond in the form of a “Wells submission” that seeks to persuade the SEC that such an action should not be brought. The Company intends to provide to the Staff a Wells submission to further explain the Company’s views and its belief that no enforcement action is warranted against the Company or any individuals associated with the Company. The receipt of the Wells Notices does not change the Company’s belief that it has complied with all laws and regulations, and therefore, the Company intends to contest any charges that may be brought. The Company is unable to predict how long the SEC process will last, the outcome of the SEC’s investigation or any action that the SEC may decide to pursue, or any other impact on the Company as a result of the proposed or any actual enforcement action.
