As previously disclosed, on June 28, 2017, Walgreens Boots Alliance, Inc. (the “Company”) entered into an Asset Purchase Agreement (the “Asset Purchase Agreement”) with Rite Aid Corporation (“Rite Aid”) and Walgreen Co., a wholly-owned direct subsidiary of the Company (“Walgreen Co.”), pursuant to which Walgreen Co. agreed to purchase certain stores, distribution centers, inventory and other specified assets from Rite Aid and its affiliates upon the terms and subject to the conditions set forth in the Asset Purchase Agreement (collectively, the “Transaction”).

The obligation of the parties to consummate the Transaction is subject to, among other things, the expiration or termination of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the “HSR Act”), applicable to the Transaction. The Company and Rite Aid filed the notification and report forms (the “Initial Filing”) required under the HSR Act with the U.S. Department of Justice (the “DOJ”) and the U.S. Federal Trade Commission (the “FTC”) on July 17, 2017. On August 16, 2017, in consultation with Rite Aid, the Company voluntarily withdrew the Initial Filing. The Company expects to re-file the notification and report form under the HSR Act with the DOJ and the FTC by August 18, 2017. If the Company re-files the notification and report form by August 18, 2017, the waiting period under the HSR Act with respect to the re-filing would be scheduled to expire on September 18, 2017, unless otherwise extended or terminated.
