Super Micro Computer Tumbles Most in Its Short History
This article is for subscribers only.
Super Micro Computer Inc. (commonly known as Supermicro) plunged in Thursday trading after Bloomberg Businessweek reported that a Chinese hack infiltrated the U.S. technology supply chain by implanting tiny chips on motherboards supplied by the company. Shares of other leading server and network-storage firms also fell. Apple Inc. and Amazon.com Inc. were among companies that found malicious microchips on Supermicro motherboards. Those companies, as well as Supermicro and China’s Ministry of Foreign Affairs, denied the Businessweek report, which is based on more than a year of reporting and more than 100 interviews.
