Apple is among the largest companies in the world, with a broad portfolio of hardware and software products targeted at consumers and businesses. Apple's iPhone accounts for the majority of the firm's sales, and Apple's other products, such as the Mac, iPad, and Watch, are designed around the iPhone as the focal point of an expansive software ecosystem. Apple has progressively worked to add new applications, such as streaming video, subscription bundles, and augmented reality. The firm designs its own software and semiconductors and works with subcontractors such as Foxconn and TSMC to build its products and chips. Slightly less than half of Apple's sales come directly through its flagship stores, with the majority coming indirectly through partnerships and distribution.

Sandisk is one of the five largest suppliers of NAND flash memory semiconductors globally. Sandisk is vertically integrated, producing substantially all of its flash chips at manufacturing sites across Japan via a joint-venture framework with Kioxia. Sandisk then repackages most of its chips into SSDs for consumer electronics, external storage, or cloud storage. Sandisk was formerly a piece of Western Digital for nine years (after being acquired in 2016) and was spun off as an independent company in 2025.
