Support scope: Directly establishes completed acquisition of all Seagen outstanding common stock on the release date and the acquired oncology portfolio. An exchange delisting notice was not obtained from this page.
Precise gap: The phrase no longer independently listed is not stated as an exchange delisting fact in the retrieved release. Full ownership is directly supported; a narrower ownership statement is proposed.
Source/data dates are supplied baseline metadata, not replaced by this check time. No alternate route, login, headers, private endpoint or payment used.
