Exhibit 99 [ZOLTEK logo] FOR IMMEDIATE RELEASE NASDAQ NMS SYMBOL: "ZOLT" - --------------------- ------------------ ------ ZOLTEK REPORTS STRONG CARBON FIBER GAINS ST. LOUIS, MISSOURI -- AUGUST 16, 2004 -- Zoltek Companies, Inc. today reported its second consecutive quarter of significant increases in carbon fiber sales and improved operating results. For the three months ended June 30, Zoltek's total revenues were $17.4 million, compared to $15.8 million in the third quarter of fiscal 2003, an increase of 10%. However, sales of carbon fibers - Zoltek's core products - were up $3.0 million, or approximately 45%, more than offsetting a $1.6 million decline in non-core operations (production of acrylic and nylon fibers for the textile markets at Zoltek's facilities in Hungary). The increased sales in the carbon fibers and technical fibers business units resulted in an approximate 30% reduction in the overall operating loss reported by the Company from a loss of $2.6 million in the third quarter of 2003 to a loss of $1.8 million in the third quarter of 2004. Also during the third quarter of 2004, the Company experienced its second sequential quarter of significant growth in customer demand for its carbon fibers. Sales increased $3.9 and $1.4 million over the first and second quarters of 2004, respectively. The improved sales in the carbon fibers segment resulted in an improvement in the overall operating loss reported by the Company from a loss of $3.2 million in the first quarter to a loss of $2.5 million in the second quarter to a loss of $1.8 million in the third quarter of 2004. For the nine months ended June 30, 2004, Zoltek's total revenues were $46.6 million, compared to $48.8 million in the corresponding period of fiscal 2003, a decline of 4%. However, over the first nine months of the current year, carbon fiber sales were up approximately 15%, which improved the overall operating loss by 13%. "Over the past two quarters, we have seen positive and clear evidence of long-term change in the marketplace for carbon fibers," said Zsolt Rumy, Zoltek's Chairman and Chief Executive Officer. "The recent developments are exciting. We are in the early stages of what we believe will be an extended period of rapid growth in demand for low-cost, high-performance carbon fibers geared to commercial applications." - 1 - [ZOLTEK logo] Zoltek Reports Strong Carbon Fiber Gains Page 2 August 16, 2004 - ---------------------------------------------------------------------------- Rumy noted that Zoltek was in the process of starting up five installed carbon fiber production lines in its Abilene, Texas facility to supply existing orders and commitments. Zoltek is also planning to make new additions to capacity in the U.S. and Hungary in 2005 and beyond. Rumy said that management's efforts to exit non-core businesses will be accelerated. "We are selling inventory and shutting down capacity in the nylon fiber operations and exiting from the acrylic textile fiber business to prepare our acrylic facilities for the manufacturing of precursor for the carbon fibers. These non-core legacy businesses are the by-product of an earlier strategic acquisition," Rumy said. "We expect that winding down these ancillary, unprofitable lines of business ultimately will have a positive effect on our future results. Even more importantly, however, we will concentrate all of our efforts in carbon fibers and technical fibers as we seek to build on our significant recent improvements in this business on both the top and bottom lines."
