Privacy for a corporation itself isn't applicable and really somewhat oxymoronic given corporation transparency requirements. Fundamentally they must be owned and managed by someone else with stake in it. Heck, income and tax information aren't even guaranteed as having a right to privacy for humans.

For corporations investors need to be able o be informed about their business operations - it is what separates it from a scam and prevents the investment system from collapsing as it would if there was nothing stopping anyone from just taking the money and running off with it. Earning and tax information wouldn't make sense as private.

That doesn't mean that employees and customers have no right to privacy because of a corporation. Just like how states don't have rights but the people making them up do.

That goes both ways, though. Apparently, most corporations are against the right to privacy ... until somebody wants to see how many tax loopholes they've used (and how much money they gave to politicians to create them).
