VIENNA, Nov 20 (Reuters) - Austrian Internet bookmaker bwin Interactive Entertainment AG said on Thursday it expected cost cuts introduced this quarter will help boost next year's core earnings to 100 million euros ($126 million) without putting its growth at risk.

After reporting a 40 percent drop in third-quarter earnings before interest, tax, depreciation and amortisation (EBITDA), it said it expected a good final quarter that would bring this year's EBITDA up to 65 million euros.

The group, which offers Internet-based sports betting, poker and games, said it expects gross gaming revenues to rise to 415 million euros this year and 430 million to 445 million euros next year.

The company had so far not given an explicit outlook for 2008 but Chief Executive Norbert Teufelberger had said on Aug. 21 that he felt comfortable with analysts' forecasts of 76 million euros in 2008 EBITDA.

Bwin shares closed at 12.40 euros on Wednesday, having lost 53 percent this year so far. They are trading at around 10 times next year's estimated earnings, about twice that of rivals such as Sportingbet, PartyGaming or 888.

PartyGaming said on Wednesday that gamblers were cutting back on visits to its websites in the economic downturn, but that it still expects to meet full-year earnings forecasts. ($1=.7921 Euro) (Reporting by Boris Groendahl; Editing by Mike Nesbit)
