One risk when investing in a public company is every other shareholder, and in this case a majority of the shareholders voted to agree to the buyout price. Tough cookie for the minority holders who opposed it, but why shouldn't they bend to the will of the majority? Why should they be rewarded after the fact?
The precedence seems terrible to me, because as a shareholder in a future case like this, it is clearly beneficial to accept whatever buyout offer is on the table, and the immediately class-action sue the buyer for the difference between that and some fictional "fair" price. What happens if every shareholder does this?
But then if judge's logic becomes the standard, then doesn't that mean you should always vote against the the deal if you think most people will vote for it?
Interesting, though, that the courts' appraisals are trusted over the market in this case. It's sort of like an anti-crowd-dynamics protection, but only for people who vote no. Your decision over whether to vote no is influenced by your knowledge of likelihood for the total vote to succeed, as henrikschroder mentions[2].
