I imagine it will fly back to EMA unpressurised after a licensed engineer has given the say so and appropriate high speed tape applied where necessary.
I recall sitting on a TEA 737-200 at BHX circa 13 years ago when we received a broadside from a loading trolley/truck which did similar damage. We then flew it to an engineering base unpressurised.
The sad thing is that as I understand it the airlines cannot sue the ground handling agencies that cause this damage due to "indemnities" and (apparently) there has never been a test case on this issue, unless others know otherwise.
From my experience it is sometimes the case that drivers of vehicles on the ramp have had pretty minimal training for the task!
