Pfizer Receives Request For Additional Information From FTC Regarding Proposed Acquisition Of Hospira

Pfizer Inc. (NYSE:PFE) today announced that it has received a request for additional information from the U.S. Federal Trade Commission (“FTC”) with respect to its previously announced proposed acquisition of Hospira. The request for information from the FTC, often referred to as a “second request,” was anticipated as part of the regulatory process under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 (“HSR Act”).

Pfizer continues to work cooperatively and expeditiously with the FTC in connection with its review. Completion of the transaction remains subject to the expiration of the waiting period under the HSR Act, governmental and regulatory approvals in certain other jurisdictions and other usual and customary closing conditions. Pfizer and Hospira continue to expect the transaction to close in the second half of 2015.
