And he gave some explanation on part of his firing as “If you're wondering why ... you haven't been paying attention. From controversial metrics in our S1 to our material weakness to two quarters of missing our own expectations and a stock price that's hovering around one quarter of our listing price, the events of the last year and a half speak for themselves. As CEO, I am accountable.”

Mason also said that the Groupon employees deserve the outside world to get a second chance and he was getting in the way of that, so with this decision, a fresh CEO can earn this chance. He also added “For those who are concerned about me, please don't be – I love Groupon, and I'm terribly proud of what we've created. I'm OK with having failed at this part of the journey.”

But nevertheless, the ousted CEO departs the company with slightly more than $212 million worth of Groupon shares.
