I take it to be a buyer based on what that quote said: 2.62 is closer to the high point of today's range and on the whole it was a price surge today.
But it is quite abnormal activity. Someone can buy or sell a million shares after hours at a fixed price on a stock like ours; who is on the other end of the trade? Or this is some hidden stuff that went through the day that has to be formally accounted for after-hours. Anywise, nothing "obvious" like justdafacts thinks. Based on today's price action, the likelihood seems a big buyer.
