Class period October 28, 2015 – November 1, 2018
Court Southern District of New York

NEW YORK, March 15, 2019 – Bragar Eagel & Squire, P.C. announces that a class action lawsuit has been filed in the U.S. District Court for the District of New Jersey on behalf of all persons or entities who purchased or otherwise acquired United Microelectronics Corporation (NYSE: UMC) securities between October 28, 2015 and November 1, 2018 (the “Class Period”).  Investors have until May 13, 2019 to apply to the Court to be appointed as lead plaintiff in the lawsuit.

The complaint alleges that defendants made materially false and misleading statements regarding UMC’s business, operational and compliance policies. Specifically, Defendants made false and/or misleading statements and/or failed to disclose that: (i) UMC conspired with Fujian to steal trade secrets from Micron relating to its research and development of DRAM; (ii) UMC hired former Micron employees for the purpose of stealing such information from Micron; (iii) the foregoing conduct placed UMC and certain of its employees at an increased risk of criminal and regulatory investigation by the U.S. government; and (iv) as a result, UMC’s public statements were materially false and misleading at all relevant times. On November 1, 2018, the U.S. Department of Justice (“DOJ”) indicted UMC, Fujian, and Chen Zhengkun a.k.a. Stephen Chen (“Chen”), a former Micron employee hired by UMC, for conspiracy to commit economic espionage, conspiracy to commit theft of trade secrets, and economic espionage (receiving and possessing stolen trade secrets). The indictment stated that the companies conspired to steal trade secrets from Micron relating to its research and development of memory storage devices. According to the indictment, the conspiracy to commit economic espionage began in or around January 2016, the conspiracy to commit theft of trade secrets began in or about October 2015, and the economic espionage (receiving and possessing stolen trade secrets) began in or about February 2016. According to the DOJ’s indictment, Chen, a Taiwanese national, resigned as the President of Micron’s subsidiary, Micron Memory Taiwan Co., Ltd. (“MMT”), in July 2015. Thereafter, Chen began working for UMC as its Senior Vice President and Fabrication Director in Taiwan in September 2015. According to the indictment, Chen, as well as agents of UMC, later hired additional former employees of Micron who stole Micron trade secrets and, at the direction of UMC employees, used such trade secrets to enhance UMC’s DRAM technologies. As news of UMC’s indictment reached the market, UMC’s ADS price fell by $0.19 per share, or nearly 10%, over the following two trading sessions to close at $1.71 per share on November 5, 2018.
