Public Service Commission of Wisconsin Approves Wisconsin Energy Acquisition of Integrys Energy

Chicago, IL – The Public Service Commission of Wisconsin (PSCW) today gave formal written approval to the acquisition of Integrys Energy Group, Inc. (NYSE: TEG) by Wisconsin Energy Corp. (NYSE: WEC). The companies announced the proposed acquisition in June of 2014.

All required federal approvals have been received, and shareholders for both companies approved the transaction in November 2014. With the approval by the Public Service Commission of Wisconsin today and the Michigan Public Service Commission last month, only Illinois and Minnesota state approvals remain outstanding. If all regulatory approvals are received, close of the transaction is anticipated by the end of the summer.

"This is another positive and important step in completing the transaction with Wisconsin Energy," said Integrys Energy Group Chairman and Chief Executive Officer Charles Schrock.
