"I didn't sell much cheaper than where it is. I'm not disappointed. I made $200 million. I never look at the last dollar," he said. "I've sold a lot of things too cheaply, but at the end, as I say, you know, my record's good enough to me. So, I'm not unhappy at all with the situation."
Family Dollar did not immediately respond to a request for comment.
Icahn, a frequent critic of corporate governance, also noted a larger issue.
"However, I want to make a point that this is one of the quintessential problems that's wrong with corporate governance today and why shareholders aren't getting these benefits because boards can go in and literally stymie these deals," he said.
Icahn, who announced a long position in Apple last year and bought more shares earlier this year, said that he remained bullish on the stock.
"We're a very sizeable shareholder," he said. "I think those followers that read my tweet when it was—what, $450, not too long ago—the ones who bought it and held it should be happy, should read my tweets more. They should become followers. So, I think they should be awful happy with this one. We haven't sold a share."
