IMPAX Receives Notice of Possible Delisting for Failure to File Form 10-K

April 06, 2005

HAYWARD, Calif.--(BUSINESS WIRE)--April 6, 2005--IMPAX Laboratories, Inc. (NASDAQ:IPXL) today announced that on April 5, 2005 it received a Nasdaq Staff determination letter indicating that IMPAX failed to comply with the requirement for continued listing set forth in NASDAQ Marketplace Rule 4310(c)(14) because IMPAX failed to file its Annual Report on Form 10-K for the fiscal year ended December 31, 2004 (the "2004 Form 10-K") with Nasdaq and, therefore, IMPAX's common stock is subject to delisting from The Nasdaq Stock Market. IMPAX intends to request a hearing before a Nasdaq Listing Qualifications Panel to review the Staff's determination, although there can be no assurance that the Panel will grant IMPAX's request for continued listing. IMPAX had previously notified Nasdaq of the delinquent 2004 Form 10-K on March 31, 2005.

The letter also informed IMPAX that, as a result of the delinquent 2004 Form 10-K, a fifth character "E" will be appended to IMPAX's trading symbol and that the trading symbol for IMPAX's common stock will be changed from "IPXL" to "IPXLE" at the opening of business on April 7, 2005.

On March 31, 2005, IMPAX announced that it was not able to file its 2004 Form 10-K by March 31, 2005. IMPAX requires additional time to complete the year-end financial closing. The nature of the restatements announced in the fourth quarter of 2004 significantly increased the complexity and scope of the year-end closing process. The delay also has been caused by the additional time required to complete the extensive Sarbanes-Oxley Section 404 internal controls requirements, necessary for the first time with this year's 2004 Form 10-K filing, and additional time required for IMPAX to investigate and evaluate potential material weaknesses or potential significant deficiencies in connection with the Sarbanes-Oxley Section 404 internal control evaluation.

IMPAX is endeavoring to complete the year-end financial closing and internal control assessment and file the 2004 Form 10-K as soon as possible, but currently is unable to predict when the 2004 Form 10-K will be filed.
