Repairing foam board?

Hi there
Im completely new to this site, but I bought my gf a 7ft foam board recently. And in delivery it has been damaged.
I have contacted delivery company, waiting reply.
Basically it has been squashed and cut. I was just wondering how to go about repairing a foam board, as it just needs to be sealed. Any special type of glue to use? to close up the gap. (pic below)
Any help would be great,
thanks
