today reported second quarter 2012 financial results.

Please refer to "Non-GAAP Financial Measures" below for a reconciliation of GAAP to non-GAAP items.

"The positive second quarter results reflect our Zomig® tablets sales in the U.S. utilizing our expanded neurology focused brand sales force, as well as increased receipt of shipments of generic Adderall XR® from our third-party supplier which led to higher sales in the quarter," said Larry Hsu, Ph.D., president and CEO, Impax Laboratories, Inc. "We are excited that our brand sales force began promoting and sampling Zomig® tablets in the U.S. on April 1. This product will support the growth of our commercial organization as we prepare for the potential launch of Rytary, our first internally developed brand product for Parkinson's Disease."

"The U.S. Food and Drug Administration (FDA) recently completed a preapproval inspection for Rytaryand an undisclosed generic product at our Taiwan facility and there were no Form 483 observations. We continue to work at resolving the recent observation made by the FDA in Hayward and have been notified that a satisfactory re-inspection will be necessary to close out the warning letter," Dr. Hsu continued.

"Our generic business pipeline has 46 pending ANDAs with more than 40 internally developed or partnered products, including many alternative dosage form products. We remain focused on pursuing strategic opportunities that are aimed at advancing our generic and brand businesses beyond our internal efforts. So far in 2012, our business development activities include the in-licensing of Zomig® on the brand side, and the acquisition of alternative dosage form generic products and a co-development, supply and distribution agreement with TOLMAR, Inc. on the generics side. With more than $354 million in cash and short-term investments and no debt, our business development activities will continue to focus on delivering growth from high-value products, technologies, and businesses in complementary dosage forms," Dr. Hsu concluded.

The Company has two reportable segments, the Global Pharmaceuticals Division (generic products & services) and the Impax Pharmaceuticals Division (brand products & services) and does not allocate general corporate services to either segment.

Global Pharmaceuticals Division revenues in the second quarter 2012 were $133.1 million, up 10% compared to the prior year period, due to higher Global product sales, net, partially offset by lower Rx Partner sales.

For the second quarter 2012, Global product sales, net, were $126.4 million, up 14% from the prior year period, primarily due to higher sales of authorized generic Adderall XR®. Partially offsetting this increase was a $2.4 million decline in Rx Partner revenues due to lower customer demand.

Gross profit of $62.6 million represented a 47% gross margin in the second quarter 2012, and was in-line with the gross margin for the prior year period, primarily due to higher sales of our authorized generic Adderall XR® product.

Total generic operating expenses in the second quarter 2012 increased slightly compared to the prior year period, as higher patent litigation and selling, general and administrative (SG&A) expenses were offset by lower investments in research and development (R&D).

Impax Pharmaceuticals Division revenues in the second quarter 2012 increased $28.1 million to $33.4 million, compared to the prior year period, due to U.S. sales of Zomig® tablets pursuant to the AstraZeneca License Agreement for which there was no comparable amount in the prior year period.

Gross profit of $15.2 million increased $12.8 million in the second quarter 2012, due to U.S. Zomig® tablet sales, compared to the prior year period. Gross margin in the second quarter 2012 was 46%, up slightly over the prior year period. The second quarter 2012 gross margin was negatively impacted by the inclusion of $14.3 million in cost of revenues for amortization and acquisition-related costs due to the Zomig® transaction.

Total brand operating expenses in the second quarter 2012 increased $2.6 million, compared to the prior year period, due to higher SG&A expenses resulting from Zomig® marketing costs and the expansion of the Company's neurology focused sales force, as well as pre-launch planning costs for Rytary, partially offset by lower R&D expenses.

General and administrative expenses in the second quarter 2012 increased $3.3 million, compared to the prior year period, primarily due to employee severance and increased personnel expenses.

Cash and short-term investments were $354.5 million as of June 30, 2012, as compared to $346.4 million as of December 31, 2011.
