I-485 pending less than 180 days, company shutting down

[north.cartman007]

Here is my situation

I-485 pending less than 180 days (pending for 3 months),
EAD received,
H1B valid for 2 more years
Company shutting down in few weeks.

1. Can I change employer B based on h1b transfer (not using the AC21 or EAD) without affecting my I-485 application?
2. Can I Apply AC21 with employer B after I-485 pending for 180 days ?

Thanks
Any input appreciated, as it will help a lot in planning

found these question in the following link, but they dont answer what happens when the company A shuts down. Can the GC application still be ported?

Question 10. Should service centers or district offices deny portability cases on the sole
basis that the alien has left his or her employment with the I-140 petitioner prior to the
I-485 application pending for 180 days?
Answer: No. The basis for adjustment is not actual (current) employment but prospective
employment. Since there is no requirement that the alien have ever been employed by the petitioner
while the I-140 and/or I-485 was pending, the fact that an alien left the I-140 petitioner before the I-
485 has been pending 180 days will not necessarily render the alien ineligible to port. However, in all
cases an offer of employment must have been bona fide. This means that, as of the time the I-140
was filed and at the time of filing the I-485 if not filed concurrently, the I-140 petitioner must have
had the intent to employ the beneficiary, and the alien must have intended to undertake the
employment, upon adjustment. Adjudicators should not presume absence of such intent and may
take the I-140 and supporting documents themselves as prima facie evidence of such intent, but in
appropriate cases additional evidence or investigation may be appropriate.

Question 11. When is an I-140 no longer valid for porting purposes?
Answer: An I-140 is no longer valid for porting purposes when:
A. an I-140 is withdrawn before the alien’s I-485 has been pending 180 days, or
B. an I-140 is denied or revoked at any time except when it is revoked based on a withdrawal
that was submitted after an I-485 has been pending for 180 days.
