What happened last week is irrelevant. If I can sell my shares on the market today for $46 and Elon is offering $54, that's a ~17% premium. It's better than nothing but not nearly enough to convince >50% of shareholders to vote in his favor. Several major ones have already said no to the offer (https://www.reuters.com/technology/saudi-prince-alwaleed-bin...).
If it was a serious offer the market would have already valued TWTR at ~$54, but it has actually gone down after Musk announced his bid.
Information about a potential takeover bid is absolutely relevant, and it's generally reasonable to calculate the premium from before that news first existed.
What happened last week was information about a potential takeover bid.
It is not at all irrelevant. I would be surprised if any reputable financial source would think of this as a 17% premium and not include last week.
gpm said the rest already as a reply.
As to the Saudi prince. Regardless of the topic. In any situation, it is hard to take the prince at face value knowing he pushed hard to successfully give the Kushners and co $2B[0]. If there’s more at play for the prince than short or medium term money, what he says is irrelevant then.
