(NASDAQ NM: IPXL) today reported financial results for the three months ended March 31, 2004. Revenues for the first quarter of 2004 were a record $38,853,000, up more than 240% compared with revenues of $11,425,000 in the prior year's first quarter, and up more than 131% over total revenues of $16,829,000 in the fourth quarter of 2003. The year-over-year increase for the first quarter was primarily due to shipments of our generic versions of Wellbutrin(R) SR (Bupropion Hydrochloride) 100 mg and 150 mg Controlled Release Tablets, which were approved by the FDA during the quarter. During the quarter, upon approval from the FDA, we also commenced shipments of Demeclocycline Hydrochloride (generic of Declomycin(R)) 150 mg and 300 mg Tablets. First quarter revenues also include $2,500,000, representing the reversal of the refundable deposit from Teva under its strategic alliance agreement related to its exercise of the exclusivity option for certain products. Net income for the 2004 first quarter was $9,048,000, or $0.14 per fully diluted share, compared with a net loss of $3,213,000, or $(0.07) per share, in the prior year first quarter. Cash, cash equivalents and short-term investments (unrestricted) were $19.5 million at March 31, 2004, compared to $15.5 million at December 31, 2003. During the first quarter of 2004, we satisfied the remaining $2.5 million refundable deposit obligation to Teva in full by issuing 160,751 shares of our common stock to Teva. As of March 31, 2004, to our knowledge, Teva owns 2,511,752 shares of our common stock, or approximately 4.3% of the outstanding common stock. Also during the quarter, the holders of Series 2 Preferred Stock converted their entire 75,000 preferred shares into 1,500,000 shares of common stock. Subsequent to the end of the quarter, IMPAX closed a private placement of $95,000,000 aggregate principal amount of 1.250% convertible senior subordinated debentures due 2024. "We are delighted to report our first profitable quarter since IMPAX Laboratories was formed in December 1999," said Barry R. Edwards, Chief Executive Officer of IMPAX. "Our research and development team's steady stream of filings, the subsequent FDA approvals of those ANDAs, positive litigation outcomes, and the dedication and hard work of our employees in all the functional areas of the Company made this goal a reality. The convertible debenture financing completed on April 5, 2004 provides us with additional financial resources going forward." Commenting on the Company's product pipeline, Larry Hsu, Ph.D., IMPAX's President, said, "The launch of our generic Wellbutrin SR represents IMPAX's single largest product opportunity to date. According to NDCHealth, U.S. sales of Wellbutrin SR 100 mg and 150 mg, marketed by GlaxoSmithKline (NYSE:GSK), were approximately $1.4 billion in the twelve months ended February 29, 2004. In addition to the generic Wellbutrin SR, our new product pipeline continues to progress through the FDA. During the quarter, we received final approvals for generic versions of Declomycin and Claritin(R)-D 24-Hour. Our generic versions of Allegra(R)-D and Tricor(R) Tablets have also been granted tentative approvals." IMPAX currently has seventeen applications pending at the FDA, including five tentatively approved, which address over $5.4 billion in U.S. branded product sales for the 12 months ended February 29, 2004.
