That's highly debatable. Does "attainder" as used in the constitution apply to corporations? To a large extent that depends on whether corporations are persons in the context of that prohibition, but there are other concerns as well. You're assuming that the answer to all such questions can be answered in favor of corporations, but that's hardly settled.
