An application for change in controller was filed with the Financial Services Authority, and a short form notification of a proposed concentration was submitted to the Commission of the European Communities.

In September 2008, MidAmerican and Constellation Energy have reached a definitive merger agreement in which MidAmerican will purchase all of the outstanding shares of Constellation Energy for a cash consideration of approximately $4.7 billion, or $26.50 per share.

The definitive agreement has been approved by both companies’ boards of directors and is subject to, among other things, shareholder and customary regulatory approvals.

Gregory Abel, president and CEO of MidAmerican, said: These filings further advance our plan to achieve prompt shareholder and regulatory approvals for our merger with Constellation Energy. This merger will bring needed long-term financial stability to Constellation Energy.
