Billionaire investor Carl Icahn said Michael Dell would lose his job as head of Dell if shareholders accept an offer for the computer maker outlined by Icahn.

Dell needs “cultural change,” and Michael Dell isn’t the person to implement that, Icahn said on Bloomberg Television.

Icahn and Southeastern Asset Management are pitching an alternative deal that would let Dell shareholders keep their stake in the company and give them either $12 a share in cash or additional shares.
