The reason I think this "may" jeopardize your I-485?
The chance to get RFE for EAD is not high, but it\'s still possible, for example, people have posted EAD RFE for unclear photographs (this should be easily done without getting company information)
My concern is that:
Is it possible for EAD RFE related to company information, for example, request you to get new employment letter or whatever you can not obtain at that time. (because company has already closed).
But if you just apply I-485 and let it sit idle for 180 days. You are safe 100% percent.
Correct me if I am wrong.
