U.S. Extends Investigation Into Chip-Gear Maker Applied Materials

(Bloomberg) — The U.S. Department of Commerce is continuing an investigation into Applied Materials Inc.’s shipments to Chinese customers, part of a broader effort to ensure that increasingly strict trade restrictions against the Asian nation are effective.

The company said in a filing this week that it had received subpoenas in May from the Commerce Department’s Bureau of Industry and Security. That followed earlier subpoenas from the agency in November of last year.
