Exhibit 99.1 PharmaFrontiers Reports First Quarter 2006 Results THE WOODLANDS, Texas--(BUSINESS WIRE)--May 15, 2006--PharmaFrontiers Corp. (OTCBB:PFTR), a company involved in the development and commercialization of cell therapies, today reported financial results for the quarter ended March 31, 2006. Highlights of the first quarter of 2006 and recent weeks include: -- Completion of $23 million financing to fund Phase IIb trial for Tovaxin(TM) and other clinical programs -- Reconstitution of board of directors with two new board members -- Lynne Hohlfeld, CPA named as vice president of finance David B. McWilliams, chief executive officer of PharmaFrontiers, commented, "We anticipate starting our Phase IIb trial during the second quarter of this year, so we have moved aggressively to ensure that our financial resources, capital structure and management team are all optimally organized and aligned to support this important milestone in our clinical program. We are ready in every sense to focus our energy and resources on our next stage of development." Financial Results The Company reported no revenue for the three months ended March 31, 2006 or in its comparative period the year before. General and administrative expenses during the three months ended March 31, 2006 were $1,075,882, compared with $1,206,715 during the same period in 2005. The decrease in general and administrative expenses is due primarily to a reduction in legal fees associated with patent filings, a lower allocation of facilities costs and overhead now allocated to research and development. This was offset in part by an increase in stock-based compensation expense. In January 1, 2006, we adopted Statement of Financial Accounting Standards No. 123 (revised 2004), "Share-Based Payment," ("SFAS 123R") which requires the measurement and recognition of compensation expense for all share-based payment awards made to our employees and directors including stock options and restricted stock based on estimated fair values. We elected to adopt the modified prospective transition method as provided by SFAS 123R and, accordingly, prior year results have not been restated. Stock-based compensation expense recognized under SFAS 123R for the three months ended March 31, 2006 was $484,392. Research and development expenses were $738,450 for the first quarter of 2006, compared with $644,264 for the same period in 2005. The increase is primarily related to an increase in consulting fees related to the rheumatoid arthritis program and a higher allocation of facilities and over costs to research and development due to increased development activities. Interest expense was $429 for the three months ended March 31, 2006, compared with $1,487,384 for the comparable quarter in 2005. The interest expense during 2005 was due to notes that were outstanding during the first quarter of 2005 which were subsequently converted into equity in June 2005. PharmaFrontiers had a net loss for the three months ended March 31, 2006 of ($2,224,450) or ($0.11) per share (basic and diluted), compared with a net loss of ($3,747,304) or ($0.37) per share (basic and diluted) for the same period of 2005. The Company had cash of $1,059,856 as of March 31, 2006 as compared with $2,560,666 as of December 31, 2005. After the close of the first quarter of 2006, the Company completed a private placement of equity, which raised $23,000,000. About PharmaFrontiers Corp.
