Icahn also said he would continue to publicly question corporate boards and management he considers are doing poor jobs for shareholders. The activist will take to Twitter to voice some of his opinions.

"If you are incensed by the actions of the Dell Board as much as I am, I hope you will choose to follow me on Twitter where from time to time I give my investment insights. I also intend to point out what I consider to be unconscionable actions by boards and discuss what remedies shareholders may take to change the situation," Icahn said.

In recent years, Icahn has won board seats on Chesapeake Energy ( CHK) and Herbalife ( HLF). The activist also recently used Twitter to announce a large stake in Apple ( AAPL) and his opinion that the company should increase its cash payouts to shareholders.
