Jack Ma and Jerry Yang are both actively working to take Yahoo!'s ( YHOO) private according to separate reports from Reuters and Bloomberg. Reuters first reported Monday that according to unnamed sources, a consortium of private equity investors Yahoo CEO and Co-founder Jerry Yang would roll over his stake in Yahoo!, which stood at 3.63% as of April 2, Reuters and co-founder, David Filo would roll his 5.9% stake as of May 11th to assist in a management buyout alongside private equity investors. Meanwhile, Bloomberg reported that Temasek, the Singaporean sovereign wealth fund may give Alibaba and its founder Jack Ma financing to buy up a 40% stake Yahoo!, according to unnamed sources. The Sunnyvale, California -based internet search provider, owns a 43% stake in Alibaba, its most highly valued asset, recently given a valuation of $13 billion in September when private equity firms Silver Lake Partners and DST Global led a consortium of investors to buy a stake in the Chinese e-commerce giant. Last month, Jack Ma, CEO of Alibaba, said he would be "very interested" in buying Yahoo!. Yahoo shares rose over $16 in early trading up over 3%. The two new twists add to an already frenetic fall for Yahoo!, the largest website in the world and second largest internet search provider. Last month reports surfaced that Yahoo was considering a sale and had hired investment bankers. In a letter to employees subsequently confirmed it hired Goldman Sachs ( GS) and Allen & Company to be advisers on strategic options. Those options now vary in a multitude of ways including a private equity, ownership or Alibaba buyout in addition to traditional mergers or asset sales. Rumors have ranged from a Microsoft ( MSFT) takeover to a buyout from Alibaba, another Yahoo! venture or private equity firms Silver Lake and Hellman & Friedman. Last week The Financial Times reported that Yahoo! ( YHOO) may be looking to sell its 35% stake in Yahoo Japan. Yahoo Japan is the U.S. online search and news giants second largest asset after its 40% holding in Chinese ecommerce company Alibaba. Currently Yahoo Japan is valued at $19 billion, making a 35% stake worth nearly $6.65 billion.
