Carl Icahn, the activist investor who pushed for some of the big changes that have taken place at Yahoo, last week announced his resignation from the company's board of directors..
In a letter to the board that was also released to reporters, Icahn said he no longer sees a need for an activist investor at Yahoo. He praised the work of Yahoo CEO Carol Bartz and said the search deal Yahoo struck with Microsoft would "provide great long-term benefits, the potential of which many still do not understand."
Icahn was one of the most vocal Yahoo critics last year, when he pushed for the removal of Jerry Yang as CEO and for Yahoo to accept an unsolicited acquisition offer from Microsoft. He accused Yang and the board of acting against the interests of Yahoo's shareholders, at one point referring to them as "self-destructive doomsday machines."
Yahoo has since replaced Yang with Bartz and entered a 10-year search and advertising deal with Microsoft. Part of the deal calls for Yahoo to use the Microsoft Bing search engine to power the Yahoo results.
"When I joined the board, the company was in a state of turmoil. In the period since then, we have all worked together to achieve much for the company, most notably bringing Carol on to be the CEO and then consummating the search deal with Microsoft," Icahn wrote in the letter.
He said he was "proud to have played a role in both these decisions."
Icahn joined the board last year after threatening to launch a proxy fight to replace the entire board and remove Yang as CEO. Ultimately, he agreed to drop the proxy battle in exchange for a board seat for himself and two other people he handpicked.
Yahoo said Icahn had been an important member of its board who has "helped us through some significant transitions."
It said it was grateful for his "active role shaping the future of Yahoo."
