closed highest of the year today, page-2

Can anyone explain the after hours trades today? At 4.10PM the after hour sale (seemingly last sale) was at $5.48 then at 4.22 PM another sale appears for 379794 at $5.564? That's over $2.11 million? A new intra day high was reached today. Perhaps even higher tomorrow going by this sale. How do you get a trade of this size or any size for that matter, after hours?
