I say if volume is low today then it will close almost flat 51 or so. And if that happens then it will open at 54 tomorrow. Not certain on after market . Probably all over the map.
If volume is high then it will close at the 52-53 range. Tomorrow could open 51-53 range.
If it closes today at 54 then tomorrow will start down put recover towards the end of the day.
So you are predicting a relatively small move from the earnings report? Certainly possible. The options are predicting a much larger move, but they do look way more overpriced than typical going into a reporting date.
