The following information was filed by CEZ, a. s. in Czech language with the
Prague Stock Exchange as required by its rules and regulations:

REPORT 1:

          PRESS RELEASE CONCERNING RESULTS OF CEZ OPERATIONS

Net Profit of CEZ Group (consolidated) in 1st Q of Year Increased by 39 percent
to CZK 10.4 billion

In the 1st Q of this year, the CEZ Group achieved net profit in the amount of
CZK 10.371 million, which represents a year-on-year increase of 39 percent. The
operating profit of the Group amounted to CZK 14.816 million.

The increase resulted from an increase in the business margin, higher sales, a
significant improvement in the operations of the Bulgarian distributors in the
CEZ group, and the addition of the Romanian Electrica Oltenia to the Group. As
opposed to the increasing revenues, the costs were kept under control and grew
at a slower rate.

"The results of operations reveal the very good situation in the company,
especially at the operational level. The results increasingly reflect our
foreign acquisitions. Operational profit of the Bulgarian distributors has
almost doubled on a year-on-year basis. In addition to the Bulgarian and
Romanian distributors, we managed to acquire the first production facilities
abroad this year. As a result of the acquisition of the Polish power plants,
Elcho and Skawina, and, newly, Bulgarian Varna, our production capacity has
increased by as much as 17 percent. This is promising for us to continue to give
our shareholders good news," said Martin Roman, Chairman of the Board of
Directors and General Manager of CEZ.

In the first quarter of this year, power generation at power plants within the
CEZ Group reached 16,763 GWh, which means a year-on-year increase by 4 percent.
From the historical point of view, these are the highest figures reached by CEZ
in the first quarter.

Power demand in the Czech Republic has increased on a year-on-year basis by 5.7
percent, which would be equal to 4.4 percent after taking into account the
influence of the cold weather in the first quarter of the year. The Czech
economy continues to grow, showing that power consumption is always linked to
the GDP development with a coefficient of roughly 0.6. Household consumption has
grown by 6.7 percent and industrial consumption by 6.5 percent.

As of the end of March, the CEZ Group had 29,817 employees, which means a
year-on-year reduction by 2,271 persons, in particular due to the pending
integration of the CEZ Group.

"The results of operation of the first quarter require us to change the
anticipated net profit of the CEZ Group for this year. Net profit should be at
the level of CZK 27.2 billion, which is more than originally planned by 0.5
billion," said Petr Voboril, Head of Finance.

REPORT 4
            CEZ HOLDS BACK WITH GOING PUBLIC ON WARSAW STOCK EXCHANGE

The plans of the CEZ energy corporation for a dual listing on the Warsaw stock
exchange were seriously affected by instability in the wake of the plunge of CO2
trading allowances, to which electricity prices in the European market responded
by also decreasing. This of course had an impact on the stock prices of energy
companies, including CEZ.

                                        8


The primary thrust of CEZ behind the listing on the Warsaw Stock Exchange is
aimed at Polish pension funds, so that an initial listing with a volatility of
stock of this magnitude would be unfortunate timing. CEZ will therefore wait for
a more propitious moment, which is likely to arrive once the outlines of the
National Allocation Plans for the next period (NAP2) have been published.

This decision bears no connection with the development on the Polish political
scene, nor is any logical connection imaginable: we never assumed that the
Polish state would become one of our stockholders.
