Dell plans to negotiate with Blackstone Group and investor Carl Icahn over new acquisition bids for the computer maker that rival an offer of more than $24 billion from investors led by founder Michael Dell.

Dell Inc. says a special committee of board members has determined the bids from buyout specialist Blackstone and Icahn could be superior to a proposal from Dell and Silver Lake Partners to buy the Texas company for $13.65 per share.

The company says Michael Dell is willing to work with third parties on alternate acquisition proposals.

Blackstone is proposing to buy the company for $14.25 per share. Icahn wants to buy up to 58 percent of Dell’s shares for $15 each.

Icahn and other investors have criticized Michael Dell’s bid as too low.
