Company announces first quarter financial and operating results

CALGARY, May 28 /CNW/ - Alternative Fuel Systems (2004) Inc. ("AFS or the Company") (TSX Venture: AFX) announced today financial and operating results for the first quarter ended March 31, 2008. President and CEO Jim Perry stated "Sales for the quarter were up by about 42% compared to the same period last year. Production at our largest natural gas pressure regulator customer in Europe has resumed, so that revenue from that product line has picked up substantially".

Mr. Perry added that "We also reached an important milestone in the first quarter, as we began shipments of engine controllers to TATA Motors of India for their ACE natural gas powered mini-truck program. These shipments mark the first time that we have participated in providing such products to a major vehicle manufacturer for volume production. It has taken a lot of time, effort and resources over the last two years to accomplish this objective. We are excited about the future prospects for work in India, and we look forward to ramping up production to address the needs of our various customers in that region".

For the three-month period ended March 31, 2008, the Company recognized total revenue of $584,780 including engineering income and interest on cash balances. In the same period of the prior year, total revenue of $425,498 was recorded. In the first quarter of 2008, a net loss of ($19,881) was incurred, compared to a loss of ($125,561) in the three months ended March 31, 2007. Mr. Perry said that "The significant reduction in loss this quarter versus the same period last year is a very positive sign. Many of our costs, such as labour, are fairly constant. With the increase in sales that we saw during the quarter, we came much closer to achieving break-even."
