Endeavor Group's decision to deny minority shareholders the ability to veto a $13 billion deal to take the entertainment conglomerate private is the latest example of a company's controlling investors risking lawsuits to avoid paying a higher deal price. At stake is a corporate governance safeguard that reassures minority investors they are getting a fair price and protects companies' stock market valuations from taking a hit on concerns a deal would undervalue them, corporate lawyers and investment bankers say. Endeavor agreed last month to be taken private by a consortium of its investors, led by private equity firm Silver Lake, which holds 71% of the voting stock in the company.
