You have equity? The entire class of shares in the company was revoked...not suspended.
You own no share any more, so how do you conclude you have equity?
Has any company that had this happen ever traded again? I think they could try to reverse merge into a shell (after 1 or two years), but current shareholders are out of luck.
I think you also could trade between two individuals, but there is no real market for revoked shares. Not really sure how you'd prove ownership, though.
