FREMONT, Calif., April 23, 2003 — Abgenix, Inc. (NASDAQ: ABGX) today reported financial results for the first quarter ended March 31, 2003.
For the quarter ended March 31, 2003, the company reported a net loss of $33.2 million or $0.38 per share, compared to a net loss of $56.5 million or $0.65 per share for the same period in 2002. The net loss for first quarter of 2002 included impairment charges of $34.7 million for unrealized losses on investments in common stock related to various collaborations.
Contract revenues for the first quarter of 2003 were $6.2 million compared to $11.0 million for the same quarter in 2002. Including interest income, total revenues for the first quarter of 2003 were $9.4 million compared to $16.3 million for the same period in 2002. Contract revenues for the quarter primarily include license fees from customers and collaborators. Such revenues typically depend on the timing of certain events and vary from quarter to quarter.
Expenses for the first quarter of 2003 were $42.4 million compared to $72.7 million for the same quarter in 2002. First quarter 2003 expenses include $11.6 million in costs of operating the company’s antibody production facilities, which started up in the first quarter. These costs are expected to continue. First quarter 2002 expenses included impairment charges of $34.7 million.
Net cash used in operating activities in the first quarter of 2003 was $33.8 million, including a reduction in accounts payable of $9.4 million, primarily due to the winding down of construction of the manufacturing plant. In addition, purchases of property and equipment totaled $16.4 million.
Abgenix ended the first quarter with approximately $345.7 million in cash, cash equivalents and marketable securities. In addition, Abgenix holds long-term investments, primarily equity in corporate collaborators, valued at $19.1 million.
“In the first quarter, we announced important collaborations that represent our strategy to become the partner of choice in antibody-based therapeutics,” stated Raymond Withy, Ph.D., president and chief executive officer of Abgenix. “We are on track to achieve our goals for this year, as we continue to advance our product development programs and prudently manage our financial resources.”
