Dow Chemical said after U.S. markets closed Monday that it has had no discussion of a leveraged buyout.
It said its board of directors fully supports its management team and the company's current strategy.
Earlier Monday, CNBC's David Faber reported that people aware of private equity interests say Dow Chemical has told them "not to bother" approaching the company.
The company statement follows a report by a British newspaper that a consortium of investors and U.S. buyout firms were preparing a bid for Dow.
Dow's shares surged on the New York Stock Exchange on Monday, after a U.K. tabloid paper reported Sunday that a consortium of Middle Eastern investors and American buyout firms is preparing a $50 billion approach for Dow Chemical in what could be the world's biggest ever leveraged buyout.
