PRAGUE, Nov 13 (Reuters) - Czech power group CEZ <
> posted better-than expected third-quarter earnings and said rising power demand will help it through the global financial crisis.However, the firm disappointed the market by not raising its full-year forecast, and its shares ended 5.62 percent lower on Thursday at 722 crowns, only slightly outperforming a 6 percent fall in the main Prague index.
CEZ, central Europe's largest listed company, said third-quarter net profit excluding minorities jumped 46 percent year-on-year to 12.3 billion crowns ($606 million), beating an analysts' consensus estimate of 11.33 billion, on the back of rising electricity prices.
Revenues edged up 3 percent to 41.4 billion crowns, slightly below market estimate.
"Overall, the results are very good and they confirm the strong fundamentals of the company," said Petr Novak, an analyst at Atlantik FT brokerage.
CEZ also said it expected to go ahead with a planned share buyback as the share price, which has fallen 47 percent since the start of the year, made it attractive.
"We always declared that there are two conditions that must be fulfilled for us to carry on with another buyback, (one of) which is an attractiveness of our share price," Chief Financial Officer Martin Novak told a news conference.
The company reiterated its full-year outlook for net profit including minorities of 48.6 billion crowns and earnings before interest, tax, depreciation and amortisation (EBITDA) of 87 billion, saying a longer shutdown at a nuclear unit must be compensated for by more expensive coal generation.
CEZ said it was ready to cut margins to ease pressure on customers hit by the year-long financial crisis that has started to squeeze central Europe's fast-growing economies.
Central European power prices playing catch up with German levels has helped lift the majority state-owned power group's profits three-fold since 2004, and many analysts had expected guidance for this year to be lifted.
Acquisitions for the low-indebted company have proven scarce, switching CEZ's focus to partnerships and greenfield projects, and CEZ ended a year-long buyback in May that helped hike its debt level to 1.2 times EBITDA from 0.3 time.
This time around, however, CEZ would likely pay for a buyback with its own funds, as it has become more expensive to borrow money.
"We will be pleased to use the free cash that we dispose of for this buyback; we are unlikely to issue a massive bond in order to buy our own shares within a month," Novak said.
CEZ had said it expected to maintain double-digit percentage profit growth into 2010 as power demand grows, and European power firms have been largely immune to the financial crisis.
On Wednesday, Germany's E.ON <EONGn.DE> confirmed an expected rise in operating profit of up to 10 percent in 2008 as a string of utilities reported forecast-beating results for the quarter.
"In our expectations, the financial crisis will influence CEZ's financial performance only marginally," Chief Executive Martin Roman said. "Electricity consumption will grow, only the pace will fall."
CEZ stock trades at 8.7 times forecast earnings, below a sector average of 12, while Germany's E.ON <EONGn.DE> trades at 9.4 times forecast earnings, and Italy's Enel <ENEI.MI> at 8.1. (Writing by Jason Hovet; editing by Simon Jessop)
