                    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."

         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.

quarter 2005 results and answer questions on Friday, August 12, at 10:00 am
CT. The conference dial-in number is (719) 457-2617. The confirmation code

This press release contains forward-looking statements, which are based upon
the current expectations of the Company. Because these forward-looking
statements are inherently subject to risks and uncertainties, there are a
number of factors that could cause the Company's plans, actions and actual
results to differ materially. Among these factors are the Company's ability
to: re-activate its formerly idle manufacturing facilities on a timely and
cost-effective basis, to meet current order levels for carbon fibers;
successfully add new capacity for the production of carbon fiber and
precursor raw material; execute plans to exit its specialty products
business and reduce costs; achieve profitable operations; raise new capital
and increase its borrowing at acceptable costs; manage changes in customers'
forecasted requirements for the Company's products; continue investing in
application and market development; manufacture low-cost carbon fibers and
profitably market them; and penetrate existing, identified and emerging
markets. The timing and occurrence (or non-occurrence) of transactions and
events that determine the future effect of these factors on the Company, as
well as other factors, may be beyond the control of the Company. The Company
undertakes no obligation to update any forward-looking statement to reflect
events or circumstances after the date of this press release.
