QUEBEC CITY, CANADA, MAY 4, 2005 - AEterna Zentaris Inc. (TSX: AEZ; NASDAQ: AEZS) today reported financial and operating results for the first quarter ended March 31, 2005. Consolidated revenues for the first quarter 2005 were $75.9 million compared to $58.4 million for the same period in 2004, an increase of 30%. Consolidated R&D expenses net of tax credits amounted to $7.9 million in the first quarter of 2005 compared to $8 million in the first quarter of 2004. Consolidated earnings from operations for the first quarter 2005 were $8 million, compared to consolidated earnings from operations of $1.6 million for the first quarter 2004, an increase of 400%. The Company's consolidated net earnings were $0.1 million for the first quarter of 2005 compared to a consolidated net loss of $2.6 million, or $0.06 net loss per share, for the comparable period in 2004. AEterna Zentaris As of March 31, 2005, the Company had consolidated cash and short-term investments of approximately $66.5 million, including $50.7 million dedicated to the biopharmaceutical segment. The Company generated consolidated positive cash flow from operating activities of $6.4 million in the first quarter 2005. The burn rate for the biopharmaceutical segment in the first quarter 2005 was limited to $0.1 million. The increases in consolidated revenues, earnings from operations and net earnings are all attributable to the strong performance of our biopharmaceutical activities combined with the continued growth of our subsidiary, Atrium Biotechnologies Inc. (TSX: ATB.sv), now owned at 50.7%. "This first quarter of 2005 has proven to be very successful for the Company," said Gilles Gagnon, AEterna Zentaris' President and Chief Executive Officer. "Many products reached new development milestones, reflecting once again our ability to strategically and continuously advance our products through the pipeline, in line with our goal of maximizing the potential of our broad and diverse portfolio. In particular, we are proud that Solvay, as well as Shionogi and Nippon Kayaku have confirmed their commitment to fully develop and financially support the late-stage clinical programs for cetrorelix, our LHRH antagonist, in endometriosis and benign prostatic hyperplasia, respectively. We are also excited with the recent commitment by our US-based partner, Spectrum Pharmaceuticals, to advance D-63153, another LHRH antagonist, into Phase II trials in benign prostatic hyperplasia and prostate cancer. With the achievement of these milestones, our development strategy for LHRH antagonists is now fully deployed," concluded Mr. Gagnon. Dennis Turpin, Vice President and Chief Financial Officer of AEterna Zentaris, added: "Our financial position remains strong with $66.5 million in consolidated cash and short-term investments. Of this amount, approximately $50.7 million is dedicated to our biopharmaceutical activities, which is sufficient to aggressively pursue our business strategy in collaboration with our strategic partners. Shortly after the end of the first quarter, our subsidiary Atrium successfully completed its initial public offering, establishing, as of today, its market capitalization at nearly $300 million. AEterna Zentaris now holds 50.7% of Atrium, which represents an important asset for our Company."
