EXHIBIT 99 ---------- [ZOLTEK logo] FOR IMMEDIATE RELEASE NASDAQ NMS SYMBOL: "ZOLT" - --------------------- ------------------------- ZOLTEK REPORTS THIRD QUARTER RESULTS ------------------------------------ ST. LOUIS, MISSOURI -- AUGUST 10, 2005 -- Zoltek Companies, Inc. today reported its results for the third quarter of its 2005 fiscal year. For the three months ended June 30, Zoltek reported net sales of $19.7 million. That represented an increase of 25% from net sales of $15.8 million in the second quarter of the current year and of 48% from net sales of $13.3 million in fiscal 2004's third quarter. In the latest quarter, Zoltek incurred an operating loss of $1.2 million, compared to an operating loss of $2.0 million in the immediately preceding quarter this year and an operating loss of $646,000 in the third quarter of fiscal 2004. "Despite some lingering startup problems in Abilene, we are making good progress on every front toward meeting our objective of combining rapid growth with solid profitability," said Zsolt Rumy, Zoltek's Chairman and Chief Executive Officer. "That is most evident in the large gain in sales and the significant reduction in our operating loss from the second to the third quarter of this year. Over the past two quarters, we have been successful in restarting all five of our carbon fiber production lines in Abilene, Texas. We are now on our way to achieving a high production rate of our total worldwide rated capacity - including facilities in Texas and Missouri in the United States and our facilities in Hungary. Our expansion plan for later this year and early next is also on target to put in place an additional 1,000 tons of Panex(R) carbon fiber and 2,000 tons of Pyron(R) oxidized tow annual capacity in September and October, with corresponding increases in our ability to produce precursor or raw material. Right now, the only practical limitation on our sales is our ability to produce. Based on the current order book, we have customers waiting for every increase in production that we plan to make in the next two years." During the third quarter, the Company had significant increases in sales of carbon fibers to large customers in the wind energy business and of technical fibers used in the production of advanced aircraft braking systems. "Wind energy is now well established as the first major commercial application for low-cost, high-quality carbon fibers, but deep-sea drilling and exploration and automobiles are not far behind," Rumy said. "We expect these industries to be the next breakthrough application in the commercial carbon fiber market." [ZOLTEK logo] Zoltek Reports Third Quarter Results Page 2 August 10, 2005 As stated in a previous press release on May 20, 2005 (available at www.zoltek.com), due to unexpected accounting change related to derivative liabilities that could cause wide swing in reported results that have no bearing on cash flows or underlying business fundamentals, the Company focuses on operating income rather than net income as the benchmark for chartering financial performance trends.
