E.ON Sells Ruhrgas Industries to CVC Capital Partners for € 1.5 Billion

E.ON is selling Ruhrgas Industries GmbH to CVC Capital Partners, a European private equity firm, for a purchase price of € 1.5 billion. Of this amount, close to € 1.2 billion is for equity, and roughly € 0.3 billion for net debt and provisions to be assumed by the purchaser.

E.ON expects the sale to yield a gain in the magnitude of € 600 million, which will be reported under US GAAP as net income from discontinued operations. Completion of the transaction, which is anticipated by the end of August 2005, is contingent on clearance by anti-trust authorities and approval by E.ON supervisory bodies.

The Ruhrgas Industries Group has leading positions in the fields of measurement and control as well as industrial furnaces worldwide. In 2004, the Group’s sales totaled approx. € 1.4 billion.

E.ON CEO Wulf H. Bernotat: ,,By selling Ruhrgas Industries we have almost completed E.ON’s transformation into a pure-play energy company. We are thus fully concentrating our Group’s strength and potential on our core business of power and gas, which we are expanding profitably both in Germany and abroad.“
