HELSINKI (Reuters) -
Rovio Chief Marketing Officer Peter Vesterbacka told the magazine that a valuation of between $700 million and $1 billion, given in a Forbes report in July, was too low.
The company should instead be worth several billion dollars, he was quoted as saying, noting Facebook games company Zynga was estimated to be worth between $20 billion and $25 billion.
"We are not selling though -- unless somebody offers enough," Vesterbacka was quoted saying in the interview published on Thursday.
Sky-high valuations of Internet-related and other technology stocks have come into focus particularly since the flotation of LinkedIn Corp, whose strong first-day premium helped spark talk of a repeat of the tech-stock bubble which burst in early 2000.
