Well of course they're going to raise prices. They're a business. This isn't happy fairy land; their cost of doing business went up, so their prices will have to go up. If businesses didn't increase their prices to match an increase in cost of goods sold, they'd quickly go out of business.
NO. This is where you're wrong. This is a business; their goal is to get money: ALL the money, at all times. If they could raise prices and make more money, they would have done it already. They're not sitting on their laurels saying "We have enough money!" only to be shaken from complacency and driven to change their price schedule because of an unexpected expense.
This money comes straight out of their value as a business. It is a loss to the shareholders.
