At 50% it might be easier to just buy up shares on the market til they have a controlling share. The number to do that sets a cap on what the buyer will pay. I don’t have numbers on-hand, but trying to move a majority of a company’s stock (buy or sell) can cause crazy swings. When I worked in hedge funds, it was a thing we worked around. Our larger trades would execute over the course of a day or several days to minimize our impact on pricing.
At 10%, many shareholders will feel that their risk-adjusted returns on the stock would do better than the buyout.
30% is likely below the costs to acquire a controlling share on the market, and above any reasonable belief in risk-adjusted returns for shareholders (barring exceptional companies).
A lot of it is wishy washy because it’s based on math, but math with presumptions baked in. How much do shareholders think their stocks are worth? How much would it cost to buy them on the open market? How much does the buyer think the stocks are worth? There are approximate answers to all of these, from which an even more approximate price needs to be determined.
