No, you didn't miss anything. Last year, same quarter, their operating income was about (1.4M)- a loss offset by the tax credits. This years, they made $1.3M. Everyone knew the credits were expiring. This after hours move is amateurs at play.
I never understood why anyone trades after hours. There aren't many shares available, so the moves are exaggerated. Someone who wants to sell is going to get burnt, as the market maker can let the stock fall.
