Yes, Hague's plan is to split the two companies, and they would have to compensate Hague shareholders for the spinoff because it is "value" that is being separated from the parent company.
How many shares and when this will happen we do not know. First must come name change, and I assume increased share value for Hague so it can show value for Solterra when it sets a price for an IPO, if that is the route they choose.
There have been guesses that Hague could set up Solterra on the Dubai or the London exchange because there are advantages for doing this. Nobody knows for sure.
