           ZOLTEK REPORTS EXCELLENT FIRST QUARTER OPERATING RESULTS
           --------------------------------------------------------

         ST. LOUIS, MISSOURI -- FEBRUARY 9, 2007 -- Zoltek Companies, Inc.
today reported accelerated sales growth trends and strong improvement in
operating performance in the first quarter of its 2007 fiscal year ended
December 31, 2006.

         On a year-over-year basis, Zoltek's sales nearly doubled - increasing
to $30.3 million for the quarter, compared to $15.6 million in the first
quarter of the previous year. On a sequential quarter basis, Zoltek's sales
increased 27% (from $23.8 million) in the quarter ended September 30, 2006.

         Operating income from continuing operations of $3.0 million for
recently completed quarter, compared to an operating loss from continuing
operations of $1.0 million in the prior year quarter. Similarly, Zoltek
reported a positive cash flow from operating activities of $3.5 million for
the three months ended December 31, 2006, compared to a negative cash flow
from operating activities of $5.7 million for the three months ended December
31, 2005.

         "It was an excellent quarter in every important operating respect,"
said Zsolt Rumy, Zoltek's Chairman and Chief Executive Officer. "Given the
continuing growth in demand for our carbon fibers, our principal challenge is
simply to execute, and that is what we are doing - with increasing success."

         "We achieved a significant improvement in utilization rates at our
carbon fiber production facilities, with more improvement possible in the near
future," Rumy continued. "Our gross margin rose from 16% in the year ago
quarter to 26% in the latest quarter. We expect to have two new carbon fiber
production lines up and running in Hungary in March, and another two lines
should be operational in April. In January, we successfully implemented a
double-digit price increase for our carbon fibers, which will mitigate the
effect of recent cost increases and provide for higher margins in the
remainder of fiscal 2007."

         Zoltek's expansion program calls for the planned addition of four
more production lines to be completed by as early as September 2007. This will
represent an additional 5 million pound (2,250 tons) per year of rated carbon
fiber production capacity. In addition to the carbon fiber expansion, the
Company plans to expand its precursor capacity to meet the new capacity
requirements and the anticipated expansion in fiscal 2008. "We are reviewing
our expansion requirements past the 2007 plans and expect to announce those
plans shortly," Rumy said.

         Financial reporting for the quarter reflected a charge of $8.4
million related to convertible debt and warrant issuances. Of this charge,
$6.4 million related to a non-cash charge for warrants issued in December 2006
to provide funds which may be required to post a bond in connection with the
continuing defense of a lawsuit alleging breaches of a supply contract with SP
Systems. Any bond amount has not yet been determined by the court. As
previously stated, Zoltek will be vigorously contesting an adverse initial
judgment in this case, including through the appeals process in federal court,
if necessary.

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: successfully resolve pending litigation; re-activate its formerly idle
manufacturing facilities on a timely and cost-effective basis, 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.

*   To provide transparency about measures of the Company's financial
    performance which management considers most relevant, we supplement the
    reporting of Zoltek's consolidated financial information under GAAP with
    "operating income (loss) from continuing operations prior to litigation
    charge." Operating loss per GAAP was $21,415 for the quarter ended
    September 30, 2006 and "income (loss) from continuing operations before
    convertible debt expense and litigation charge" which is a non-GAAP
    financial measure. These non-GAAP financial measures should be considered
    in addition to, and not as a substitute or superior to, the other measures
    of financial performance prepared in accordance with GAAP. Using only the
    non-GAAP financial measures to analyze our performance would have material
    limitations because its calculation is based on the subjective
    determination of management regarding the nature and classification of
    events and circumstances that investors may find material. Management
    compensates for these limitations by utilizing both the GAAP and non-GAAP
    measures of its business. Zoltek believes the presentation of these
    measures is useful to investors because they are more indicative of the
    Company's underlying business performance and, since the Company expects,
    based on the recent amendment to its September 2005 financing package, the
    Company no longer has outstanding any convertible debt or warrants that
    require derivative accounting.
