I recently read that Caribou Coffee was purchased by a private equity company for $340 million. This is surprising yet at the same time not all that surprising to see the second biggest coffee chain next to Starbucks get bought out. People have been speculating on a buyout for years. I've been writing about Caribou Coffee (former ticker symbol CBOU) since 2009 here on the blog. I remember back in either 2009 or 2010 Caribou was actually trading for not that much over its net tangible equity value. The recent purchase price was for over 30 times earnings.
