Many businesses are small businesses, that are private individuals. They report their income as personal income and from that income pay their employees and their expenses, often with little left over for personal expenses. Now many are also Christians, Catholics or evangelical who don't believe in sterilzation or abortions on demand or in some cases birth control, so why should they be forced to cover these thing that go against their religious conscience? There are plenty of clinics or PP offices that cover these expenses. So why burden those who oppose it unnecessarily?
