The Complaint alleges that defendants made false and/or misleading statements and failed to disclose material adverse facts about the Company’s operations and financial prospects. Specifically, defendants misled investors that there were significant risks that the Company would be unable to fulfill the requirements of an agreement with Apple, Inc. to supply sapphire material; and that, as a result the Company was facing a liquidity crisis.

On September 9, 2014, Apple revealed that its new iPhone 6 and iPhone 6 Plus smartphones utilized Corning’s Gorilla Glass for the display instead of GT Advanced’s sapphire material as investors were expecting. On this news, shares of GT Advanced declined $2.29 per share, nearly 13%, to close on September 9, 2014, at 14.94 per share, on unusually heavy volume.

On October 6, 2014, GT Advanced announced that the Company was filing for bankruptcy protection under Chapter 11. According to the Company, as of September 29, 2014 GT Advanced had approximately $85 million of cash remaining. On this news, shares of GT Advanced declined $10.25 per share, nearly 93%, to close on October 6, 2014, at $0.80 per share, on unusually heavy volume.

If you are a member of the Class described above, you may move the Court no later than December 8, 2014, to serve as lead plaintiff, if you meet certain legal requirements. To be a member of the Class you need not take any action at this time; you may retain counsel of your choice or take no action and remain an absent member of the Class.
