NO CLASS HAS YET BEEN CERTIFIED IN THE ABOVE ACTION. UNTIL A CLASS IS CERTIFIED, YOU ARE NOT REPRESENTED BY COUNSEL UNLESS YOU RETAIN ONE. YOU MAY ALSO REMAIN AN ABSENT CLASS MEMBER AND DO NOTHING AT THIS POINT. YOU MAY RETAIN COUNSEL OF YOUR CHOICE. According to the lawsuit, defendants throughout the Class Period made false and/or misleading statements and/or failed to disclose that: (1) Insys had overstated its 2015 net revenue; (2) Insys had misstated its sales allowances for 2016; (3) accordingly, Insys lacked effective internal controls over financial reporting; and (4) as a result, Insys's public statements were materially false and misleading at all relevant times. On March 15, 2017, Insys announced during after-hours trading that "[t]he Audit Committee of the Company's Board of Directors has been conducting an independent review of the Company's processes related to estimation of, and increases to, certain sales allowances recorded during 2016, with a potential reduction of 2015 net revenue and pre-tax income not expected to exceed $5 million, as well as extended payment terms offered to certain customers during the third quarter of 2016." On this news, shares of Insys fell $0.49 per share or approximately 5% to close at $10.06 per share on March 16, 2017, damaging investors. A class action lawsuit has already been filed. If you wish to serve as lead plaintiff, you must move the Court no later than May 16, 2017. A lead plaintiff is a representative party acting on behalf of other class members in directing the litigation.
