FOR IMMEDIATE RELEASE

AtheroGenics Reports Second Quarter 2007 Financial Results

ATLANTA, GA – July 26, 2007 – AtheroGenics, Inc. (Nasdaq: AGIX), a pharmaceutical company focused on the treatment of chronic inflammatory diseases, today reported financial results for the second quarter and six months ended June 30, 2007.

AtheroGenics recorded revenues of $30.3 million for the second quarter of 2007, as compared to $6.3 million recorded for the same period in 2006. For the six months ended June 30, 2007, revenues increased to $41.7 million, as compared to $10.4 million for the comparable period in 2006. The increase in both periods principally reflects the recognition of the remaining unamortized balance of an upfront license fee due to the termination of a license agreement with AstraZeneca in the second quarter. Amortization of $20.8 million and $27.1 million was recorded in the second quarter and six month periods, respectively. Also contributing to revenue recorded in the second quarter and six month periods were research and development service fees of $9.4 million and $14.6 million, respectively, for administration of the FOCUS clinical trial, which is currently in the process of concluding.

Research and development expenses for the second quarter of 2007 increased to $22.3 million from $16.4 million for the same period in 2006.  For the six months ended June 30, 2007, research and development expenses increased to $42.3 million, compared to $32.7 million for the six months ended June 30, 2006.  The increase in both periods was due primarily to FOCUS trial expenditures, which are being funded by AstraZeneca, and start-up costs for the company’s Phase III diabetes study, ANDES (AGI-1067 as a Novel Anti-Diabetic Agent Evaluation Study). This increase in research and development expenses was partially offset by a decrease in expenses incurred for the ARISE clinical trial, which has been completed.

Marketing, general and administrative expenses increased to $3.6 million in the second quarter of 2007 from $3.2 million in the second quarter of 2006. For the six months ended June 30, 2007, marketing, general and administrative expenses increased to $7.5 million, compared to $6.9 million for the same period in 2006. These increases were primarily due to costs for the company’s marketing department, which was formed during the second quarter of 2006.

The second quarter of 2007 also included restructuring and impairment costs as follows:

$ in millions                                           Loss per share

Non-cash manufacturing transition costs                     $   7.5                                                         $ 0.19

Other restructuring and impairment costs                          2.5                                                            0.06

Total                                                                            $ 10.0                                                         $ 0.25

Manufacturing transition costs represent the write-off of impaired assets as a result of the transition of commercial manufacturing activities from AstraZeneca. Other restructuring costs include severance and asset impairment costs from an organizational restructuring that was undertaken in the second quarter.

Interest income decreased to $1.6 million in the second quarter of 2007 from $2.4 million reported for the comparable period in 2006. Interest income decreased to $3.5 million for the six months ended June 30, 2007, compared to $4.6 million for the same period in 2006.  The decrease in both periods was due to reduced levels of invested cash.

AtheroGenics reported a net loss of $6.1 million, or $0.16 per share, for the second quarter of 2007, as compared to $13.1 million, or $0.33 per share, for the same period in 2006.  For the six months ended June 30, 2007, AtheroGenics reported a net loss of $18.8 million, or $0.48 per share, as compared to $32.3 million, or $0.82 per share for the same six month period in 2006.

At June 30, 2007, cash, cash equivalents and short-term investments totaled approximately $115 million. Near term cash requirements for the company were reduced in early July, with the exchange of $38 million of convertible debt due in 2008 for $60 million in convertible debt due in 2011.

"The positive results in pre-specified diabetes endpoints reported from our ARISE clinical study of AGI-1067 were achieved in a well-treated patient population, and we’re on track to start the ANDES Phase III clinical study of AGI-1067 in patients with type 2 diabetes in the third quarter,” stated Russell M. Medford, M.D., Ph.D., President and Chief Executive Officer of AtheroGenics.

2007 Updated Guidance

AtheroGenics updated its full year 2007 earnings guidance as a result of the restructuring and other transactions and estimated that full year 2007 loss per share will be in the range of $1.35 to $1.45. The company reiterated its full year 2007 cash flow guidance, estimating that cash outflow will be in the range of $61-$66 million.
