Linda, no, there is perpetual confusion here. The GSA has two periods.
1) A binding period, when everybody who signed it is bound, and cannot leave or stop it.
2) A non-binding period, when anybody COULD exit it, but it would require an ACTIVE SPECIFIC ACTION to leave it
The "expiration" date is a misnomer. It is the time where by we transition from #1 to #2.
At this time, it has not been "renewed" (re-signed) to go from #2 back to #1.
But it still is totally in force and the next steps would be:
a) A POR is confirmed using the GSA
b) It is re-signed/renewed to cause it to become binding again
c) A party ACTIVELY withdraws by making such an announcement and FILING.
