You have said that if Moshiri owns 90%+ of the shares, then any minority shareholder can compel him to purchase their shares at market value (and he can also force them to sell).
That’s not correct - the squeeze out rights under the Companies Act only applies if there is an exit/takeover bid.
For example, if a third party buyer wanted to acquire 100% of Everton and Moshiri owned 90% of the shares, in those circumstances he could rely on CA 2006 to force the minority shareholders to sell to the purchaser (and likewise, they could compel him to secure an offer from the purchaser for their shares if they wanted).
The squeeze out right is essentially a statutory drag along and tag along with a 90% threshold - however it can’t just be used to force share purchases/sales when there is no takeover bid.
