The Hungarian office further enhances the business network of the CEZ Group which currently covers, aside from the Czech homeland and Hungary, also Germany, Poland, Slovakia, Bulgaria, and Romania. For the nearest future, the CEZ Group plans branch offices also in other countries of Southeastern Europe. "CEZ has clearly conveyed its vision to become Number One in the power market in Central and Southeastern Europe. But this expansion consists not only of the acquisition of new subsidiaries - we also follow the path of developing our business and trade. We believe that today's opening of this branch office of CEZ majorly enhances the electricity offer for traders, distributors (utilities), and consumers (final customers) on the Hungarian market," said Martin Roman, Chairman of the Board and CEO of CEZ, on occasion of the opening ceremony. The Hungarian spin-off of the CEZ Group already acquired all necessary trade licenses and finalized its first deal in May. "Our goal is to acquire, and then consolidate, a strong position as player in the Hungarian market. In a first stage, we will focus not only on domestic trading, but also on cross-border electricity sales," adds Gabor Hornai, Branch Director of the Hungarian office and long-term expert for the Hungarian energy market. The CEZ group has been conducting its foreign expansion with success, both in the area of electricity distribution and as regards the acquisition of production sites. Since January 2005, the corporation owns three Bulgarian distribution companies, and towards the end of last year, CEZ secured also the Romanian distribution company Electrica Oltenia, which supplies those areas with electricity that are in the immediate neighbourhood of the Bulgarian catchment area for distribution of the CEZ Group. In the area of power generation, CEZ has recently completed the acquisition of two Polish power companies, Elcho and Skawina; at the beginning of May, the corporation executed the privatization agreement on the purchase of the Bulgarian heat power plant Varna. 2 SIGNATURES Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned, thereunto duly authorized.
