RE:RE:What Legally Has To Happen By June 30th? June 30th is just an escape clause if either side wanted to walk away at that point, but I don't see that happening. Could it be that there are a lot of moving parts behind the scene and that is way it is taking longer than expected - most likely a good thing.
"The Arrangement Agreement is terminable by the parties in limited circumstances that are customary for a transaction of this nature, including by either party if the Arrangement has not been completed by June 30, 2021 (the "Outside Date")."
