There is no requirement that companies maximize shareholder value. At best you might be able to hold them to something in their charter, but generally lawsuits attempting this are thrown out pretty quickly, and even if it's not, except in cases of blatant mismanagement, it's difficult to prove that someone else there would done better with different decisions. I know this meme is persistent, but it's really not true. If it were, you'd end up with ridiculous situations, like every company with a down quarter would be sued in an effort to get a windfall out of a loss.
