(WTAJ) — In the wake of a global helium shortage, Party City is closing 45 locations.

The party supply store hasn’t announced which stores will be affected, but has said the closings will happen throughout the year.

There are currently 870 Party City stores in the U.S. and Canada, including one in State College.

Party City CEO James Harrison wrote that the closings would help the company “focus on the most profitable locations,” among other things.
