Yahoo shareholders angry at the failure last weekend of takeover talks with Microsoft have only until late next week to mount a campaign to force the internet company to reconsider, following a manoeuvre by Yahoo to put the matter behind it. Despite the growing backlash against Yahoo’s board over its handling of the Microsoft negotiations, analysts said the odds were still low that any organised shareholder opposition to the company’s directors would emerge, particularly given the tight deadline. Yahoo set the deadline on Monday evening as it announced a July 3 date for its long-delayed annual meeting. The company had earlier put off the meeting rather than face a proxy fight from Microsoft, which had threatened to nominate its own slate of directors to replace the existing board.
