Levi & Korsinsky is investigating potential claims on behalf of purchasers of Impax Laboratories Inc. (“Impax” or the “Company”) (Nasdaq: IPXL) securities concerning possible breaches of fiduciary duty. For more information, click here: http://zlk.9nl.com/impax-laboratories-ipxl/. On March 4, 2013, shares of Impax fell more than 20 percent after the Company’s announcement that, upon an inspection of the Company’s Hayward, California plant, the FDA issued a new Form 483 with twelve observations, three of which are designated as repeat observations from past inspections. As a result of the FDA’s concerns, new and pending applications that relate to the facility may be withheld until the Form 483 problems are resolved. The FDA previously sent Impax a warning letter in January 2011 based on an inspection of the Hayward, Calif., plant, and found other problems in a March 2012 inspection. Following the March 2012 inspection, the FDA said the original problems had been addressed, but found problems in the facilities’ quality control laboratory. On March 5, 2013, the day following the Company’s announcement, Impax shares closed at $14.80, down 26% from the prior day’s closing price.
