Dell's largest external shareholder turns up heat in percolating battle over company's sale

ROUND ROCK, Texas – Dell’s largest independent shareholder is turning up the pressure against the proposed $24.4 billion sale of the struggling personal computer maker to a group of investors that includes its CEO.

In a letter Tuesday, Southeastern Asset Management demanded that Dell Inc. provide a list of the company’s other stockholders. Obtaining that information could help Southeastern rally support for a shareholder mutiny to block the deal.

Dell says it will review Southeastern’s request.

Dell’s board of directors last month announced plans to sell the company to founder and CEO Michael Dell and other investors led by Silver Lake for $13.65 per share.

Southeastern contends Dell is giving its CEO a bargain. The firm believes Dell is worth closer to $24 per share.
