That's exactly what they did. The article says $172m disgorgement (how much the CFTC thinks they profited from this), $311m restitution (the amount the CFTC thinks JPM harmed others but didn't capture), and $436m civil penalty ("naughty boy" fine).
I read that also, but it wasn't clear to me that the disgorgement was the profit, I assumed it was just what they had on hand from their takings, like if you rob a bank and get caught with $5k left then they would disgorge you of the $5k and then deal with the rest later.
