Federman & Sherwood Announces the Filing of a Securities Class Action Lawsuit against GT Advanced Technologies, Inc.


Oklahoma City, OK (October 13, 2014) – On October 9, 2014, a securities class action lawsuit against certain executives officers and directors of GT Advanced Technologies, Inc. (NASDAQ: GTAT) (the “Company”) as well as the underwriters of the Company’s public offering of 3.00% Convertible Senior Notes due 2020 and the Company’s public offering of common stock, both conducted on or around December 4, 2013 (the “Offerings”).  The action was filed in the United States District Court for the District of New Hampshire on behalf of all investors of the Company’s securities during the period between November 5, 2013 through October 6, 2014 (the “Class Period”).  This action seeks to recover damages against Defendants for alleged violations of the federal securities laws under the Securities Exchange Act of 1934 (the “Exchange Act”) and the Securities Act of 1933 (the “Securities Act”) on behalf of investors that purchased securities pursuant or traceable to the Offerings.


The Complaint alleges that during the Class Period and/or in the offering materials for the Offerings, defendants misrepresented and/or concealed the Company's cash position, expected cash position and revenues, ability to meet the milestones under a critical agreement with Apple for the production of sapphire material, and the progress that the Company was making developing the facility that would produce the sapphire material.


On October 6, 2014, the Company announced that it was experiencing a liquidity crisis and filed for bankruptcy in the United States Bankruptcy Court for the District of New Hampshire. On this news, the price of the Company’s stock declined from $11.05 per share to $0.80 per share. Similarly, the price of the Company's 3.00% Convertible Senior Notes due 2020, which had a face value of $1,000 per note, declined from $1,083 per note to $315 per note.


Plaintiff seeks to recover damages on behalf of all of the Company’s shareholders who purchased securities during the Class Period or who purchased or otherwise acquired securities through the Offerings and are therefore a member of the Class as described above.  You may move the Court no later than Monday, December 8, 2014 to serve as a lead plaintiff for the entire Class.  However, in order to do so, you must meet certain legal requirements pursuant to the Private Securities Litigation Reform Act of 1995.
