Clovis Oncology, Inc. announced that it and certain of its subsidiaries (collectively, the “Debtors”) have voluntarily initiated a Chapter 11 proceeding in the United States Bankruptcy Court for the District of Delaware (“Bankruptcy Court”) and will seek to sell their assets through a court supervised sales process. The Debtors have filed various “first day” motions with the Bankruptcy Court requesting customary relief that will enable them to transition into Chapter 11 without material disruption to their ordinary course operations, including seeking authority to obtain debtor-in-possession (“DIP”) financing and pay employee wages and benefits.
