PROPOSED MERGER OF PARENT COMPANY WITH WISCONSIN ENERGY CORPORATION

Proposed Merger of Parent Company with Wisconsin Energy Corporation

In June 2014, our parent company, Integrys Energy Group, entered into an Agreement and Plan of Merger with Wisconsin Energy Corporation. This transaction was approved unanimously by the Boards of Directors of both companies. It is subject to various approvals, including the FERC, Federal Communications Commission, PSCW, and other regulatory commissions. In addition, this transaction is subject to the approval of the shareholders of both companies, for which special shareholder meetings will be held on November 21, 2014. On October 24, 2014, the Department of Justice closed its review of the transaction and the Federal Trade Commission granted early termination of the waiting period under the Hart-Scott-Rodino Act. The transaction is also subject to other customary closing conditions. The transaction is expected to close in the summer of 2015.
