Warner Communications denied a buy-out rumor.

The New York-based entertainment company said it is “not in conversations with anyone concerning the possibility of being taken private or merging with another corporation.” Warner broke its usual policy of not commenting, Warner Vice President Geoffrey W. Holmes said, because a story published by the New York Post appeared to prompt unusual stock activity. The Post reported that Warner would be taken private by the company’s chairman, Steven J. Ross, and oilman Marvin Davis in a deal valued at about $2.8 billion.
