Activist investors generally outlive their usefulness pretty quickly. I doubt EIM will back out completely since the stock is forecast to have a lot of upside. They have really achieved everything they set out to, though. I think their days of actively running things are coming to a close.
I was also cautiously optimistic when they showed up. They said all the right things, but they also took a pile of cash out of our back pockets while they were showing us how to succeed. Money well spent? We shall see. Looks like it for now.
