EXHIBIT 99.1 AtheroGenics Reports First Quarter 2004 Financial Results ATLANTA, GA - April 22, 2004 - AtheroGenics, Inc. (NASDAQ: AGIX), a pharmaceutical company focused on the treatment of chronic inflammatory diseases, today reported financial results for the quarter ended March 31, 2004, reflecting steady progress in the Company's research and development activities. Research and development expenses for the first quarter increased to $14.0 million, compared to $10.3 million for the prior year period. The increase in research and development spending was due primarily to costs associated with ongoing patient recruitment and new clinical development staff hires for the Company's ARISE Phase III clinical trial evaluating AGI-1067 in atherosclerosis. Also contributing to the increase in expenses were costs associated with the ongoing OSCAR Phase II clinical trial evaluating AGIX-4207 in rheumatoid arthritis and preclinical studies involving the Company's asthma program. General and administrative expenses totaled $1.7 million for the first quarter of 2004, compared to $1.3 million for the prior year period. The majority of the increase in general and administrative expenditures resulted from higher insurance premiums and business development expenses related to partnership activities. AtheroGenics recorded interest expense of $1.3 million during the quarter, compared to interest expense of $18,631 in the first quarter of 2003. The higher interest in 2004 relates to convertible notes issued by the Company in August 2003. AtheroGenics' net loss for the first quarter of 2004 was $16.6 million, or $(0.45) per share, compared to $11.5 million, or $(0.35) per share, for the same period in 2003. AtheroGenics ended the first quarter of 2004 with $115.5 million in cash, cash equivalents and short-term investments. "Since the beginning of the year, we've made significant progress with our maturing clinical programs for AGI-1067 in cardiovascular disease and AGIX-4207 in rheumatoid arthritis," said Russell M. Medford, M.D., Ph.D., President and Chief Executive Officer of AtheroGenics. "We look forward to reporting important Phase II clinical trial results from both of these programs later in the year."
