Glancy Prongay & Murray LLP ("GPM") announces that a class action lawsuit has been filed on behalf of investors who purchased Insys Therapeutics, Inc. ("Insys" or the "Company") (NASDAQ: INSY) securities between February 23, 2016 and March 15, 2017, inclusive (the "Class Period"). Insys investors have until  May 16, 2017 to file a lead plaintiff motion.

Investors suffering losses on their Insys investments are encouraged to contact Lesley Portnoy of GPM to discuss their legal rights in this class action at 310-201-9150 or by email to

On March 15, 2017, Insys disclosed that it would delay the release of its financial results for the fourth quarter and full year 2016 in order to complete an independent review of the Company's processes related to sales allowances and extended payment terms. The company further disclosed that the review could result in a reduction of 2015 net revenue and pre-tax income. On this news, shares of Insys fell approximately 5% during intraday trading on March 16, 2017, thereby injuring investors.

The Complaint filed in this class action lawsuit alleges that throughout the Class Period, Defendants made materially false and/or misleading statements, as well as failed to disclose material adverse facts about the Company's business, operations, and prospects. Specifically, Defendants made false and/or misleading statements and/or failed to disclose that: (i) Insys had overstated its 2015 net revenue; (ii) Insys had misstated its sales allowances for 2016; (iii) accordingly, the Company lacked effective internal controls over financial reporting; and (iv) as a result of the foregoing, Insys's public statements were materially false and misleading at all relevant times.

If you purchased shares of Insys during the Class Period you may move the Court no later than  May 16, 2017 to ask the Court to appoint you 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.
