It's an established legal precedent that a publicly-traded business' highest priority is to maximize its stock value, to preserve and protect the owners' investment. CEOs and boards of directors who violate that, who commit their corporation toward any other goal that might affect the bottom line can be and have been sued -- successfully.
It's understandable. Investors are the true owners of the company, while the directors are merely the caretakers. Naturally the owners have a right to assert their will, to protect their property.
But every now and then, a company will buck that obligation, finding some other cause beyond profit worthy, and simply do what they believe is "right" despite what it might do to that sacrosanct stock investment. It's incredibly rare, because it's often led to those directors finding themselves sued or fired.
One of those rare occasions has occurred. One company has decided that, despite the tremendous damage their stores in the South have suffered, they will not cut and run. They have brought in employees from all over, put them up in temporary shelters, and even give away prescriptions simply on the word of the customer -- but they will not pull out of the South.
I think I might need to transfer my prescriptions to CVS soon...
