Exhibit 99 [ZOLTEK logo] FOR IMMEDIATE RELEASE NASDAQ NMS SYMBOL: "ZOLT" - --------------------- ------------------ ------ ZOLTEK REPORTS STRONG CARBON FIBER GROWTH IN 2004 ST. LOUIS, MISSOURI -- DECEMBER 29, 2004 -- Zoltek Companies, Inc. today reported a significant increase in revenues and improved results of continuing operations for fiscal 2004, accompanied by a sharply improved outlook in its core carbon fiber business. For fiscal 2004, ended September 30, Zoltek reported net sales of $45.3 million, up 15%, or $5.9 million, from $39.4 million in fiscal 2003. Strategic carbon fiber sales increased 40%, or $5.2 million, from $13.2 million in fiscal 2003. Zoltek reported an operating loss from continuing operations of $5.5 million, a decrease from the loss of $9.4 million in fiscal 2004. Despite significant improvement in the core carbon fiber business in fiscal 2004, Zoltek's net loss for the fiscal year increased 7%, or $1.1 million, due primarily to two factors. First, the increase in the loss of discontinued operations of $5.8 million for fiscal 2004 compared to a loss of $3.6 million in fiscal 2003 related to exiting non-core, underperforming businesses - the nylon fiber and acrylic textile divisions of its Hungarian subsidiary. Second, the company reported a non-cash expense of approximately $1.8 million to reflect the amortization of warrants issued as part of a refinancing package. "The principal challenge for Zoltek today is no longer one of proving our concept or strategy," said Zsolt Rumy, Zoltek's Chairman and Chief Executive Officer. "The commercialization of low-cost, high-performance carbon fibers in new markets outside of aerospace is clearly happening - with wind energy as the first big breakthrough application. Now our challenge is one of execution and ramping up to meet the fast-growing demands of an established base of customers." In recent weeks, Zoltek has announced a major long-term supply contract for carbon fibers and carbon fiber material with Vestas of Denmark, the world leader in the manufacture of wind turbines and the rotor blades that power them. In 2004 Zoltek re-started the first of five continuous carbon fiber production lines installed at its Abilene, Texas plant. The company expects to have all five operating in the first half of its current fiscal year and is planning to add two new lines later in fiscal 2005 at its Hungarian operation and to substantially increase its capacity again in fiscal 2006, all in response to customer demand. 1 [ZOLTEK logo] Zoltek Reports Strong Carbon Fiber Growth in 2004 Page 2 December 29, 2004 - ---------------------------------------------------------------------------- Zoltek Companies, Inc. will host a conference call to review fourth quarter/fiscal year-end 2004 results and answer questions on Tuesday, January 4, 2005, at 10:00 am CT.
