Alibaba Group and Softbank Corp (9984.HKG) are in advanced talks with Blackstone Group (BX.NYSE) and Bain Capital about making a takeover bid for Yahoo! Inc (YHOO.NASDAQ), Bloomberg reported, quoting three people with knowledge of the matter. A bid may value Yahoo at more than US$20 a share, two of the people said, though Alibaba hasn't decided on a final price or whether to proceed. Yahoo's board is meeting today to discuss previous offers for a minority stake from TPG Capital and a group led by Silver Lake. Silver Lake's bid for the stake valued Yahoo at about US$16.60 a share, while TPG Capital's offer was higher, said people familiar with the matter. "We would prefer the entire group get sold at a higher premium," said Di Zhou, an analyst at Thornburg Investment Management, which holds shares in Yahoo. "It definitely has to be much higher than US$16.60."
