Yahoo!'s CEO Jerry Yang signaled earlier this week that the Internet company is willing to sell.
Ballmer, at a conference in Sydney, on Friday said Microsoft may still have partnership deals with Yahoo!, Bloomberg reports.
"We're not interested in going back and re-looking at an acquisition," Ballmer said. ``I'm sure there are still opportunities for some kind of partnership around search.'' He didn't elaborate on the potential partnerships, Bloomberg reports.Yang said he's ready to return to the bargaining table with Microsoft if Microsoft remains interested in buying the Internet company. "To this day, I believe the best thing for Microsoft to do is to buy Yahoo," Yang said Wednesday at the Web 2.0 summit in San Francisco, the Associated Press reported. Yang said he and the rest of Yahoo!'s board "remain open to everything" after Google (GOOG) abandoned an ad-search deal between the two companies. Google's move to back out of the partnership renewed investor speculation that Microsoft may bid for all or part of Yahoo!. Yang rejected bids earlier this year from Microsoft of as much as $47.5 billion, or $33 a share. Shares of Yahoo! traded as low as $11.25 last week. Yahoo! closed Thursday at $13.96.
