The wild card continues to be Athenahealth CEO Jonathan Bush, who owns a small stake in the company but continues to be a cultural force. Bush may also have Jeffrey Immelt in his corner. The former GE CEO was brought on in February to be the board chair, a move that Elliott specifically questioned in its offer to Athenahealth earlier this month. Following Elliott's proposal, Dodge thought Bush might be content leaving the company if an activist investor was constraining his ability to innovate.
