Impax Laboratories Provides Update on Status of Warning Letter Resolution for its Hayward Facility

February 9, 2012

Outlines Progress in Executing Growth Strategy and on Implementing Quality Improvement Initiatives

HAYWARD, Calif.--(BUSINESS WIRE)-- Impax Laboratories, Inc. (NASDAQ: IPXL) today provided an update on the status of its resolution of the previously disclosed warning letter issued by the U.S. Food and Drug Administration (FDA) covering its Hayward manufacturing facility. Late last year, Impax received an acknowledgement letter from the FDA stating that it had received a complete response from Impax to the warning letter. However, a satisfactory re-inspection is required to close out the warning letter and the re-inspection by the FDA has not occurred to date. Therefore, the Company’s previously stated goal for completing the closing out of the warning letter before the end of February 2012 may not occur. Until such re-inspection is completed and the warning letter is closed out, approval of the Company’s pending drug applications listing the Hayward manufacturing facility as a manufacturing location may be withheld by the FDA.

“We worked as quickly and diligently as possible to ensure we addressed all FDA concerns, and look forward to a timely resolution,” said Larry Hsu, Ph.D., president and CEO, Impax Laboratories. “At the same time, we have been successfully executing our growth strategy, including pursuing external growth opportunities, further advancing our generic and brand R&D pipeline, and servicing our customers. Our focus on achieving these objectives is evident in several recent positive events, including obtaining a long-term licensing agreement for Zomig®, advancing our pipeline with the filing of a New Drug Application for IPX066 and submitting 11 Abbreviated New Drug Applications in 2011.”

As part of its Global Quality Improvement Program, the Company said it has revised its Standard Operating Procedures, made key staffing changes, revalidated manufacturing processes, conducted additional training, and purchased and validated new equipment.

Hsu added, “Improving the operation of all of our production facilities and company-wide quality systems has strengthened our Company, and continuous improvement will remain a top priority. We appreciate the communication and guidance provided by the FDA throughout this process and look forward to their re-inspection of our Hayward facility.”

Yesterday Impax received notice from the FDA that it has forfeited exclusivity on its generic version of Doryx 150mg.
