* Q3 earnings due Wednesday, Nov 11 after the market closes
* OIBDA seen down 10 percent, revenue down 12 percent
* Markets watching guidance after revenue target dropped
PRAGUE, Nov 6 (Reuters) - Telecom group Telefonica O2 Czech Republic <
> is expected to post a 10 percent drop in third-quarter core profit on waning consumer demand, a Reuters poll showed on Friday.Operating profit before interest, tax, depreciation and amortisation (OIBDA) was forecast at 6.47 billion crowns ($375 million).
Revenue was seen falling 12 percent to 14.8 billion crowns, while net profit was estimated down 18 percent at 2.64 billion.
Apart from lower consumer spending, Czech Telefonica was also hit by a reduction on interconnection and roaming fees imposed on telecom operators by the European Union.
"We expect a decline in wireline and mobile revenues due to the bad economic environment," Jindrich Svatek, an analyst at Raiffeisenbank in Prague, said in a note.
The company's results a year ago were boosted by a one-off item that lifted revenue by 960 million crowns and profit by around 300 million.
Analysts said markets would be watching for changes in guidance after the group dropped its full-year revenue outlook last quarter due to low market visibility. But it has confirmed 2009 OIBDA should be flat to down 4 percent.
If third-quarter market expectations were met, it would mean a 6.4 percent drop in OIBDA for the nine-month period, making the full-year forecast difficult to fulfil and subject to a possible revision, analysts said.
Shares in the biggest Czech telecom firm, 69 percent owned by Spanish group Telefonica <TEF.MC>, have held broadly steady this year on the back of its 12 percent dividend yield.
But at the same time, the stock lagged the market's recovery this year, having grown by 1 percent as Prague's index <
> jumped 30 percent.Following is a summary of analyst estimates (figures in billions of crowns):
Q3 2009 Average Median Range Q3 2008
Revenue 14.81 14.72 14.52-15.64 16.83
OIBDA 6.47 6.46 5.95- 7.08 7.22
Operating profit 3.45 3.47 2.84- 3.96 4.11
