Overall, the companies do not face such a big threat from the bargaining power of suppliers. This is mainly because, just as they are reliant on Apple Inc. for their sales, so are their suppliers on them. The benefits of supplying the materials required for the manufacture of the various Apple products trickle down to the suppliers of Apple’s suppliers. This is because a business guarantee for their customer, is business guaranteed for them, more or less. However, the companies do incur manufacturing costs, component costs, and labor costs, in order to come up with the products to supply their customers.
