Applied Materials — Headquarters: Santa Clara, CA

NoteThe source explicitly confirms the claim in multiple places: (1) in the infobox stating 'Headquarters Santa Clara, California, U.S.', (2) in the opening paragraph stating 'The company is headquartered in Santa Clara, California', and (3) in the Locations section stating 'Applied moved into its Bowers Avenue headquarters in Santa Clara, California, in 1974'. All three references consistently confirm that Applied Materials's headquarters is in Santa Clara, CA.
