SAN FRANCISCO - Brushing aside the threat of a disruptive takeover battle that could batter its shaky stock, Internet pioneer Yahoo Inc. on Monday reiterated its refusal to sell to Microsoft Corp. for less than $45 billion.
Yahoo's defiance, spelled out in a letter to Microsoft Chief Executive Steve Ballmer, marked the latest twist in a tug-of-war pitting two high-tech icons trying to mount a more formidable challenge to online search and advertising leader Google Inc.
The increasingly tense struggle now appears to have reached a turning point after more than two months of mostly behind-the-scenes maneuvering.
Analysts believe the two rivals will either broker a friendly transaction before the end of the month or wrestle for the allegiance of Yahoo's shareholders in a showdown that could drag into the summer.
Most people following the saga still seem to think Microsoft -- the world's richest tech company -- holds the upper hand over Yahoo, which has been mired in a two-year slump and unable to find an alternative deal that would trump Microsoft's original offer of $44.6 billion, or $31 per share.
"They both have some leverage, but the greatest leverage still appears to rest with Microsoft," said Morton Pierce, a Washington lawyer who advises on corporate mergers and acquisitions.
Ballmer turned up the heat on Yahoo over the weekend by setting an April 26 deadline for the Sunnyvale, Calif.,-based company to accept Microsoft's offer.
If Yahoo's board doesn't relent, Ballmer threatened to lower Microsoft's bid and ask Yahoo's shareholders to replace the 10 directors resisting a takeover in a "proxy" contest.
