ITEM 1. BUSINESS

This Annual Report on Form 10-K for the fiscal year ended September 30, 2010 and the information incorporated by reference herein contain forward-looking statements, which are inherently subject to risks and uncertainties. See “—Special Note Regarding Forward-Looking Statements.”

General Development of Business

Zoltek Companies, Inc. is an applied technology and advanced materials company. Our mission is to lead the commercialization of carbon fiber through our development of a price-competitive, high-performance reinforcement for composites used in a broad range of commercial products which we sell under the Panex^® trade name. In addition to manufacturing carbon fiber, we produce an intermediate product, a stabilized and oxidized acrylic fiber used in flame- and heat-resistant applications which we sell under the Pyron^® trade name. We were founded in 1988 and incorporated in Missouri.

Overview

We led the development of the carbon fiber commercialization concept and we believe we are the largest manufacturer primarily focused on producing low-cost carbon fibers for commercial applications. We have spent over 15 years developing and refining our proprietary technology and manufacturing processes and capacity. Until fiscal 2004, the high cost of carbon fibers precluded all but the most demanding applications, limiting carbon fiber use primarily to aerospace and sporting goods applications.

From 2005 to 2007, there was a significant increase in demand for carbon fibers from the aerospace and commercial manufacturing industries. Airbus and Boeing initiated production of new generation aircraft utilizing carbon fiber composites in critical airframe structures (e.g., fuselage and wings). At about the same time, the adoption of carbon fibers in longer wind turbine blades created a new demand for commercial carbon fibers. This triggered a significant divergence of demand for carbon fibers between aerospace and commercial applications.

The divergence in the aerospace and commercial applications led in fiscal 2006 and 2007 to strains on our ability to meet all the demand from our wind energy customers and we were unable to take on new customers. When we were capacity-constrained, potential customers understandably would not commit to new large-scale applications without demonstrated assurance of adequate future supplies. In view of the supply shortages, we embarked on an expedited capacity expansion which now has been completed. As a result we now have sufficient capacity to meet demand from current wind energy customers and produce carbon fibers for additional large-scale applications. At the same time, manufacturers of carbon fibers for aerospace applications added substantial capacity to meet demand for aircraft production.

The decline in revenue during our recently completed fiscal year was primarily due to pricing decreases effective early in the fiscal year due to market pressures. During fiscal 2010, the commercial carbon fibers markets we serve continued to be negatively impacted by the recessionary economic conditions in the United States and international economies. These market conditions and over-supply of carbon fiber constrained pricing levels during fiscal 2010. At the same time, our largest customer moved to a just-in-time inventory program which caused a temporary reduction in sales volume. The cost of our principal raw material increased substantially during fiscal 2010 as unscheduled shutdowns in production of acrylonitrile (“ACN”) in Europe coupled with an increase in demand for ACN drove market prices up more than 100% by the end of fiscal 2010. In addition, many of our customers are being impacted by the global economic downturn and difficult capital market conditions. Management believes that these customers’ reactions of reducing inventories and slowing orders is temporary and that Zoltek is well positioned to supply our current customers and new customers with their commercial carbon fiber needs as opportunities arise and economic conditions and capital markets improve.

We are aggressively marketing to obtain new business in both existing and new applications. New applications tend to require relatively long sales cycles due to the new product development and manufacturing and engineering investments customers must make to incorporate carbon fiber composites into their products. Targeted application areas include automotive and aerospace secondary structures. During 2010, we have added additional sales personnel in Asia, focusing on markets in China, India and Korea and have begun to see some success through new customers and sales in those regions. We expect our market development efforts will be successful over the long run.

In addition to the adverse impact of the global economic downturn, three other key factors in 2009 and 2010 led to declines in our revenues, operating earnings and margins. First, after years of growing at a 20-25% annual rate, worldwide growth in electricity generation from wind energy has slowed. Second, market conditions and over-supply of carbon fiber depressed prices and caused a decline in revenue. Third, available unused capacity, as discussed under “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” was responsible for $12.8 million in unallocated costs (including depreciation) during fiscal 2010, without contributing to revenues or gross profit. While Zoltek is confident that the additional capacity will be quickly absorbed when the wind energy business returns to a more robust growth rate and new customers and applications develop, available unused capacity will continue to negatively impact gross margins and operating income. We could take steps to significantly reduce these charges in the future, but we view them as an investment in maintaining our facilities and core staff in a ready mode to minimize the cost and time to restart facilities as market conditions change.

In order to manage our business, we focus on three separate business segments: carbon fiber segment, technical fiber segment and corporate/other segment which consists of ancillary activities not directly related to the carbon fiber or technical fiber segments.

Business Strategy

Our business model focuses on low and sustainable pricing facilitated by low production costs, rapidly scalable capacity and a product line that offers various value-added product and process enhancements.

The principal elements of our business strategy include the following:

Sustainable Price Leadership. We market carbon fibers for use as a base reinforcement material in composites at sustainable price levels resulting in predictable composite costs per unit of strength and stiffness that compare favorably with alternative base construction materials. We believe our proprietary process and equipment design technology enable us to produce carbon fibers at costs substantially lower than those generally prevailing in the industry and to supply carbon fibers for applications that are not economically viable for our higher-cost competitors. We believe that, with our targeted cost structure, we can maintain sustainable pricing that makes it attractive for customers to commit to high-volume applications.

Support for New Commercial Markets and Applications Development. To further accelerate the commercialization of carbon fibers and carbon fiber composites across a broad range of mass-market applications, we have pursued various initiatives, including partnerships with potential users of carbon fibers to act as catalysts in the development of new low-cost, high-volume products. We believe that our supply relationships with customers for wind energy applications are the direct result of these development efforts. These efforts were recognized as Zoltek was named 2009 “Supplier of the Year” by Vestas Blades A/S, the blade manufacturing division of Vestas Wind Systems A/S.

Capacity Leadership to Keep Pace with Long-Term Demand Growth. We believe that our decision to build and maintain significant available capacity will allow us the ability to enter into additional long-term supply arrangements with high-volume customers. We have developed, and are continually seeking to improve, proprietary continuous carbonization line designs in order to increase efficiency and shorten lead time from the time of the decision to add lines to the time when the lines become operational. In addition, we have continually improved our ability to produce acrylic fiber precursor at low costs and in sufficient quantities to support our growth in carbon fiber capacity. The ability to increase capacity in response to the growth of the commercial markets is essential to encouraging development of large-volume applications.

Development of Model for Long-Term Joint Ventures with Strategic Partners. Our industry currently has no established means for supplying identified large scale applications for which carbon fiber composites have been proven to offer transformational technology, such as structural use in mass produced cars to increase fuel efficiency through reduced weight and improved safety due to superior strength and stiffness. Accordingly, Zoltek is seeking to leverage its proprietary expertise by developing a business model with the goal of proliferating carbon fiber technology to new customers in capital intensive industries who desire to partner with us to invest in the plants necessary to launch these high volume applications. Although we expect it will take some time and our approach will evolve to address opportunities as they develop, we believe this strategy can support a quantum leap in the commercial carbon fiber industry.

Targeted Applications

We have identified targeted applications for our products with high growth potential across a variety of industries. Among them are:

•

Wind Energy

According to the Global Wind Energy Council (GWEC), the total market for wind turbines was approximately 45 billion Euros ($63 billion) in 2009. GWEC predicts that in 2013, global wind generating capacity will stand at 332 GW, up from 120 GW at the end of 2008. We believe that Asia, particularly China, will see tremendous growth in wind energy over the next ten years. Zoltek believes that as the industry moves to supply off-shore wind turbines that are larger in size, they will continue to incorporate more carbon fibers into their designs. This means that the underlying carbon fiber demand for wind turbine applications should grow at a faster rate than the wind market itself.

Zoltek believes it is the leading supplier of the low-cost, high-performance carbon fibers used in building the largest and most advanced of these wind turbines.

•

Deep Sea Drilling

As the price of oil on the world market continues to fluctuate, oil exploration companies have moved out into deepwater, developing reserves beneath the ocean floor a mile or more below the water’s surface. As a result, demand for strong yet lightweight materials able to stand up to the harsh subsea environment has increased, with a corresponding peak of interest in composites. One of those growth areas has been in buoyancy modules. In another application, a major producer of deep sea drilling platforms has tested composite rods utilizing our carbon fibers in fabrication of umbilical products and found them to deliver equal or superior performance at affordable cost, compared to composite rods utilizing aerospace grade carbon fibers. The composite rods are designed to demonstrate the ability to succeed where steel cables begin to fail — in counteracting the greater axial loads encountered in ultra deepwater, meaning depths exceeding 8,000 feet. At these depths, steel is subject to deformation or stretching. Additional test projects are being planned to demonstrate the effectiveness of carbon fibers in other deep sea drilling applications.

•

Aerospace Secondary Structures

Zoltek is actively pursuing a new market with large-volume potential: sales of carbon fiber to leading airplane makers for use in secondary structures such as floors, luggage bins and seats. We believe airplane manufacturers are concerned about future availability and pricing of large quantities of carbon fibers, as all newly designed commercial planes will incorporate extensive utilization of carbon fiber composites. Zoltek can offer considerably lower cost structures than the manufacturers of aerospace-grade carbon fibers and we also have the competitive advantage of being able to deliver large volumes of carbon fibers on a timely basis. Airplane makers are looking for every possible opportunity to reduce fuel burn by eliminating weight, but they are also concerned about their competitive position. They have already turned to carbon fiber for making the flight-worthy primary structures of their most advanced airplanes, and now they are interested in ways to make other structures that use super-lightweight carbon fiber composites.

•

Automotive

Zoltek believes automotive applications are destined to become the largest user of carbon fibers. For years there has been an upward trend in the use of carbon fiber reinforced composites in the manufacture of small-volume and many times hand-made cars. Examples include the Tesla which uses Zoltek fibers for the entire car and Corvette which use Zoltek carbon fibers for a few specialized parts. While these applications have been growing steadily, the real explosion in demand will come from expanded adaptation of carbon fiber composites into large scale series models produced on an assembly line. Carbon fiber composites in automotive applications are suitable for structural components such as front-end modules, leaf springs and many other chasis components.

In fiscal 2010, Zoltek formed of a new subsidiary, Zoltek Automotive, LLC, to speed development of volume automotive applications for large-tow carbon fiber. Our objective is to make the adaptation of carbon fiber technology and processes easy and efficient for automotive companies and their suppliers by developing new production methods that will enable customers to fabricate cost-effective carbon fiber intermediate products. To this end, Zoltek Automotive, LLC is working directly with tier one automotive suppliers on advancing this technology and assisting them in the utilization of carbon fiber with existing and new manufacturing machinery and processes.

•

Aircraft Brakes

We believe our technical fibers segment is the largest supplier of oxidized fibers to the leading manufacturers of aircraft brakes. A substantial majority of commercial and defense aircraft has incorporated carbon-carbon brakes into their design due to their superior heat resistance, friction properties and light weight. This business should continue to afford a steady revenue stream with significant growth potential.

Customers

In fiscal 2010, 2009 and 2008, we reported net sales of $49.5 million, $74.2 million and $75.1 million, respectively, to Vestas Wind Systems, a leading wind turbine manufacturer, which represented 38.6%, 53.6% and 40.4% of our net sales, respectively, during such periods. Zoltek has also expanded its customer base to include additional wind energy and deep sea drilling customers consistent with its objective of expanding into its targeted applications. The related open accounts receivable balances at September 30, 2010 and 2009 were $11.0 million and $21.1 million, respectively. The Company reported net sales of $24.6 million in fiscal 2008, to Gamesa Group, another leading wind turbine manufacturer, which represented 13.3% of our net sales, during that fiscal year. These were the only customers that represented greater than 10% of consolidated net sales during these years.

Backlog

Sales of our products are generally made pursuant to customer purchase orders. In recent years, our customers have increasingly demanded shorter order lead times and “just-in-time” delivery performance. While we have multi-year contracts with certain major customers, most of these contracts specify the customers’ indicated requirements that will be supplied by us and the terms under which the sales will occur, not the specific quantities to be procured. As a result, twelve-month order backlog is not a meaningful indicator of future revenues for us.

Company Operations

We have manufacturing plants in Nyergesujfalu, Hungary, Guadalajara, Mexico, Abilene, Texas and St. Charles, Missouri. Our plant in Hungary is our major carbon fiber manufacturing facility. Our Hungarian plant also manufactures acrylic fiber precursor, the raw material that we use to make carbon fibers and oxidized fibers. Our Texas plant houses carbon fiber manufacturing lines and value-added processing capabilities. Our Missouri plant is primarily dedicated to the production of technical fibers for aircraft brake and other friction applications and also produces limited amounts of carbon fibers and houses a research and development facility. In addition, we have facilities in Salt Lake City, Utah where we design and build composite manufacturing equipment and can produce resin pre-impregnated carbon fibers, called prepregs.

Our facility in Guadalajara, Mexico was acquired in October 2007. We expect it will supply our North American operations with low-cost precursor and will serve as an additional site for carbon fiber production. The first phase of retrofitting the Mexican acrylic precursor plant and installation of carbon fibers lines has been completed. During the fourth quarter of fiscal 2010, the plant began limited production of carbon fiber, but delayed precursor production and full utilization of carbon fiber lines pending resumption of market demand. The Mexico plant, which we expect will eventually be our largest facility, will substantially increase our capacity to produce low-cost carbon fibers on a timely and cost-effective basis, and further extend our leadership in the growing commercial carbon fibers sector.

Acrylic fiber precursor comprises a substantial portion of the total cost of producing carbon fibers. With the addition of our Mexico precursor facility, we expect to have ample supply of high quality, low-cost precursor to supply our foreseeable future requirements.

An element of our strategy is to offer customers value-added processing of the fibers that we produce. Our longer-term focus is on creating integrated solutions for large potential end users by working directly with carbon fiber customers in the primary applications that we target. We perform certain downstream processing, such as weaving, knitting, blending with other fibers, chopping and milling, and preparation of pre-form, pre-cut stacks of fabric. We also manufacture carbon fibers preimpregnated with bonding resin, or prepregs. In addition, our Salt Lake City-based Entec Composite Machines subsidiary designs and builds composite manufacturing equipment and markets the equipment along with manufacturing technology and materials.

We also provide composite design and engineering for development of applications for carbon fiber reinforced composites. We reported research and development expenses of $8.2 million, $7.6 million and $8.1 million in fiscal 2010, 2009 and 2008, respectively. For historical financial information regarding our various business segments, see Note 11 of the Notes to Consolidated Financial Statements.

Competition

Our carbon fibers and technical fibers business segments compete with various other producers of carbon fibers. We are the only publicly-held company that is a “pure-play” in carbon fibers, while all the other six principal competitors’ carbon fiber operations are a relatively small part of their total business. Our existing six major competitors have substantially greater research and development, marketing, financial and managerial resources than we do. We are aware of no single manufacturer of carbon fiber products that competes across all of our product lines and applications. We believe our business model distinguishes us from other carbon fiber manufacturers in supporting the long-term growth of the commercial carbon fiber market.

To varying degrees, depending on market conditions and supply, we compete with aerospace grade carbon fiber producers, such as Hexcel Corporation and Cytec Industries of the United States and Toray Group, Toho Tenax and Mitsubishi Rayon of Japan. These carbon fiber producers tend to market higher cost products than our products, with a principal focus on aerospace structural and high price industrial applications. SGL Carbon is the most direct competitor which also uses a textile-type precursor which they purchase from various suppliers.

The aerospace carbon fiber manufacturers have tended to enter into direct competition with us primarily when they engage in significant discounting to protect their market share and to sell in spot markets. SGL Carbon currently is our principal competitor in the oxidized fiber market.

The principal areas of competition for the carbon fibers and technical fibers business segments are sustainable price, quality, development of new applications and ability to reliably meet the customer’s volume requirements and qualifications for particular programs. Carbon fiber production also requires substantial capital expenditures for manufacturing plants and specialized equipment, know-how to economically manufacture carbon fibers to meet technical specifications and the ability to qualify carbon fibers for acceptable performance in downstream applications.

International

The Company conducts its carbon fiber products operations primarily in North America and Europe. The Company sells its carbon fibers globally. There are unique risks attendant to the Company’s foreign operations, such as currency fluctuations. For additional information regarding our international operations, see Note 11 of the Notes to Consolidated Financial Statements and the information included under “Item 1A. Risk Factors.”

Sources of Supply

As part of its growth strategy, the Company has developed its own precursor acrylic fibers, which are used as the principal raw material for all of its carbon fibers. The primary source of raw material for the precursor is ACN (acrylonitrile), which is a commodity product with multiple sources.

Environmental

The Company’s operations generate various hazardous wastes, including gaseous, liquid and solid materials. The operations of the Company’s carbon fibers and technical fibers business segments utilize thermal oxidation of various by-product streams designed to comply with applicable laws and regulations. The plants produce air emissions that are regulated and permitted by various environmental authorities. The plants are required to verify by performance tests that certain emission rates are not exceeded. The Company does not believe that compliance by its carbon fibers and technical fibers operations with applicable environmental regulations will have a material adverse effect upon the Company’s future capital expenditure requirements, results of operations or competitive position. There can be no assurance, however, as to the effect of interpretation of current laws or future changes in federal, state or international environmental laws or regulations on the business segment’s results of operations or financial condition.

Employees

As of September 30, 2010, we employed approximately 362 persons in our North American operations and approximately 733 in our European operations.

Our U.S. employees are not represented by any collective bargaining organizations. By law, most employees in Hungary are represented by at least one labor union. At Zoltek Zrt., our Hungarian subsidiary, there are two active unions (some Zoltek Zrt. employees belong to both unions). Management meets with union representatives on a regular basis and there have not been any problems or major disagreements with either union in the past five years. We believe that overall our employee relations are good. At our Mexican subsidiary employees are also represented by a union which was selected by our subsidiary.

Item 1A. Risk Factors

The following are certain risk factors that could affect Zoltek’s business, financial results and results of operations. These risk factors should be considered in connection with evaluating the forward-looking statements contained in this Annual Report on Form 10-K because these factors could cause the actual results and conditions to differ materially from those projected in forward-looking statements. Before you buy the Company’s securities, you should know that making such an investment involves a high degree of risk, including the risks described below. The risks that we have highlighted here are not the only ones that the Company faces. If any of the risks actually occur, the Company’s business, financial condition, results of operations or cash flows could be negatively affected. In that case, the trading price of its securities could decline, and you may lose all or part of your investment.

Our growth and profitability will depend on increases in demand for carbon fibers and entering into new supply relationships.

Historically, our business has been adversely affected during periods of oversupply and capacity constraints. For years prior to fiscal 2004, our financial results were adversely affected by industry oversupply conditions which inhibited adoption of carbon fibers for non-aerospace applications as existing and potential customers were reluctant to commit to incorporate carbon fiber composites into their products due to concerns about the availability of carbon fiber in large volumes at predictable pricing. During 2006 and 2007, the divergence in the aerospace and commercial applications and our new contracts with wind energy customers led to strains on our ability to meet all the demand from our wind energy customers and we were unable to take on new customers.

We currently have sufficient capacity to meet demand from current wind energy customers and produce carbon fibers for additional large-scale applications. Our capacity expansion resulted in excess capacity costs of $12.8 million in 2010. Our future profitability and growth will depend upon our ability to enter into supply relationships with new customers for existing applications utilizing our carbon fibers and the development of new markets for large-scale applications which incorporate our carbon fiber products. Development of new customers for existing applications and new markets for our carbon fiber products will require substantial technical, marketing and sales efforts and the expenditure of significant funds. Development of new markets for carbon fibers may not occur. Our business, operating results and financial condition could be materially and adversely affected if new customers and markets for our carbon fibers products do not develop.

Increases in sales of our carbon fiber products are subject to long sales cycles of our customers.

Our future profitability and growth will depend primarily upon our ability to enter into supply relationships with new customers for existing applications utilizing our carbon fibers and the development of new markets for a broad range of large-scale applications which incorporate our carbon fiber products. Our ability to increase sales of our carbon fiber products is subject to relatively long sales cycles of our customers due to new product development, manufacturing and engineering investments our customers must make to incorporate carbon fiber composites into their products.

A limited number of customers generate a significant portion of our revenue and they may terminate their contracts with us in the event of certain changes in control or may require that we make penalty payments in the event we fail to perform.

For fiscal 2010, our largest customer represented approximately 38.6% of our revenue and our three next largest customers accounted for 19.4% of our revenue. We anticipate that significant customer concentration will continue for the foreseeable future, although the composition of our largest customers may change from period to period. A significant portion of our total sales in fiscal 2010 were to customers in the wind energy market. Significant changes in demand for our customers’ wind turbines, the shares of their requirements that are awarded to us or changes in the design or materials used to construct their products could result in a significant loss of business with these customers. Our contracts with certain customers allow them to terminate their agreements with us or require us to make substantial penalty payments in the event we fail to perform our obligations under our agreements with them. The loss of, or significant reduction in the purchases by, these customers or any other significant customers could have a material adverse effect upon our future revenues and business, results of operations, financial condition or cash flow.

We reported net losses from continuing operations for fiscal 2010, 2009, 2007 and each of the five fiscal years preceding it.

Although we reported net income in fiscal 2008, we have reported losses from continuing operations of $7.1 million, $12.3 million, $17.1 million, $38.2 million, $65.8 million $2.0 million, $4.2 million, and $6.3 in fiscal years 2002, 2003, 2004, 2005, 2006, and 2007, 2009, and 2010 respectively. Net losses from continuing operations for the fiscal 2002, 2003, 2004 and 2005 were attributable primarily to the cost of development and preliminary execution of our carbon fiber commercialization strategy.

Demand for our carbon fiber products may be adversely affected by the current economic and credit environment.

The United States and international economies recently have experienced (and continue to experience) a period of slow economic growth. A near-term economic recovery is uncertain. In particular, the current credit and housing crisis, the increase in U.S. sub-prime mortgage defaults, potential terrorist acts and similar events, continued turmoil in the Middle East and war in general could contribute to a slowdown for products that require significant capital expenditures, including demand for large-scale projects that incorporate our carbon fibers. If the economic recovery slows down as a result of recent economic, political or social turmoil, we may experience decreases in the demand for our carbon fiber products, which will harm our operating results.

Our operations and sales in foreign countries are subject to risks.

For fiscal 2010, approximately 58.6% of our revenues were derived from products supplied by our operations in Hungary. Our operations in Hungary and Mexico and our sales in other foreign countries are subject to risks associated with foreign operations and markets including the fact that many members of our senior management are resident in the United States, foreign currency fluctuations, unexpected changes in regulatory, economic or political conditions, tariffs and other trade barriers, longer payment cycles for accounts receivable, potentially adverse tax consequences, restrictions on repatriation of earnings and the burdens of complying with a wide variety of foreign laws. These factors could have a material adverse effect upon our future revenues and business, results of operations, financial condition or cash flow.

Our ability to fund and manage our anticipated growth will affect our operating results.

The growth in our business has placed, and is expected to continue to place, a significant strain on our management and operations. In order to effectively manage potential long-term growth and to reach growth targets, we will need to add to our carbon fiber manufacturing capacity, have access to adequate financial resources to fund significant capital expenditures and maintain gross profit margins. We must also pursue a growth strategy and continue to strengthen our operations, including our financial and management information systems, and expanding, training and managing our employee workforce. There can be no assurance that we will be able to do so effectively or on a timely basis. Failure to do so could have a material adverse effect upon our future revenues and business, results of operations, financial condition or cash flow. Additionally, in the event that we need to obtain debt financing in the future to fund our growth, recent uncertainty in the credit markets could affect our ability to obtain debt financing on reasonable terms.

Our operations are dependent upon our senior management and technical personnel.

Our future operating results depend upon the continued service of our senior management and our technical personnel, and the management personnel in our domestic and international operations. Our future success will depend upon our continuing ability to attract and retain highly qualified managerial and technical personnel. Competition for such personnel is intense, and there can be no assurance that we will retain our key managerial and technical employees or that we will be successful in attracting, assimilating or retaining other highly qualified personnel in the future.

Our operating results may fluctuate.

Our quarterly results of operations may fluctuate as a result of a number of factors, including the timing of purchase orders for and shipments of our products, our ability to successfully operate our expanding production capacity and changes in production levels. Therefore, quarter-to-quarter comparisons of results of operations have been and will be impacted by the timing of such orders and shipments. In addition, our operating results could be adversely affected by these factors, among others, such as variations in the mix of product sales, price changes in response to competitive factors and interruptions in plant operations.

Developments by competitors may reduce demand for our products and technologies, which may adversely affect our sales.

We compete with various other participants in the advanced materials and textile fibers markets. All of our six principal competitors have substantially greater research and development, manufacturing, marketing, financial and managerial resources than we do. In addition, existing carbon fiber producers, including those that supply aerospace applications, may refocus their activities to produce carbon fiber for commercial applications that compete more directly with us and certain producers have announced plans to do so. Developments by existing or future competitors may render our products or technologies less competitive. In addition, we may not be able to keep pace with new technological developments.

The price volatility of many of our raw materials and energy costs may result in increased production costs, which we may not be able to pass on to our customers.

A substantial portion of our raw materials are subject to price volatility and a significant portion of our manufacturing costs are energy costs. The cost of our primary raw material, ACN, increased by more than 100% after the end of fiscal 2009. We may not always be able to promptly raise product prices and, ultimately, pass on underlying cost increases to our customers. In addition, our competitors may be able to obtain raw materials at a lower cost than we can. Additional raw material and energy cost increases that we are not able to pass on to customers or the loss of a large number of customers to competitors as a result of price increases could have a material adverse effect on our future revenues and business, results of operations, financial condition or cash flow.

We could be adversely affected by environmental and safety requirements.

Our operations require the handling, use, storage and disposal of certain regulated materials and wastes. As a result, we are subject to various laws and regulations pertaining to pollution and protection of the environment, health and safety. These requirements govern, among other things, emissions to air, discharge to waters and the generation, handling, storage, treatment and disposal of waste and remediation of contaminated sites. We have made, and will continue to make, capital and other expenditures in order to comply with these laws and regulations. These laws and regulations are complex, change frequently and could become more stringent in the future.

In addition, we may be required to comply with evolving environmental, health and safety laws, regulations or requirements that may be adopted or imposed in the future or to address newly discovered information or conditions that require a response. Although most of our properties have been the subject of environmental site assessments, there can be no assurance that all potential instances of soil and groundwater contamination have been identified, even at those sites where assessments have been conducted. Accordingly, we may discover previously unknown environmental conditions and the cost of remediating such conditions may be material.

Our business depends upon the maintenance of our proprietary technology.

We depend upon our proprietary technology that is not subject to patent protection. We rely principally upon trade secret and copyright laws to protect our proprietary technology. We regularly enter into confidentiality agreements with our key employees, customers and potential customers and limit access to and distribution of our trade secrets and other proprietary information. These measures may not be adequate to prevent misappropriation of our technology or to assure that our competitors will not independently develop technologies that are substantially equivalent or superior to our technology. In addition, the laws of other countries in which we operate may not protect our proprietary rights to the same extent as the laws of the United States. We are also subject to the risk of adverse claims and litigation alleging infringement of intellectual property rights.

Our existing lines of credit expire on January 1, 2011 and August 30, 2011 and failure to extend or replace these facilities could have a material adverse effect on us.

Our existing $10.0 million U.S. line of credit and our $9.5 million Hungarian line of credit expire on January 1, 2011 and August 30, 2011, respectively. Based on our existing relationships with our lenders and our current financial condition, we believe that we will be able to extend these credit facilities beyond their current expiration dates or, if necessary, replace them. The failure to extend or replace our credit facilities on favorable terms could have a material adverse effect on our business, operating results or financial condition.

We have incurred and will continue to incur increased costs and demands upon our management as a result of complying with the laws and regulations affecting public companies, which could affect our operating results and make it more difficult to attract and retain qualified management.

As a public company, we have incurred and will continue to incur significant legal, accounting and other expenses, including costs associated with public company reporting requirements. We also have incurred and will incur costs associated with corporate governance requirements, including requirements under the Sarbanes-Oxley Act of 2002, as well as rules implemented by the SEC and the NASDAQ Global Select Market. The expenses incurred by public companies generally for reporting and corporate governance purposes have increased. These rules and regulations have increased our legal and financial compliance costs and have made some activities more time-consuming and costly. It is possible that these new rules and regulations may make it more difficult and more expensive for us to obtain director and officer liability insurance, and we may be required to accept reduced policy limits and coverage or incur substantially higher costs to obtain the same or similar coverage than used to be available. As a result, it may be more difficult for us to attract and retain qualified individuals to serve on our board of directors or as our executive officers.

Our stock price has been volatile and may continue to fluctuate.

Our stock price has fluctuated substantially over the past several years. Future announcements concerning us or our competitors or customers, quarterly variations in operating results, announcements of technological innovations, the introduction of new products or changes in product pricing policies by us or our competitors, developments regarding proprietary rights, changes in earnings estimates by analysts or reports regarding us or our industry in the financial press or investment advisory publications, among other factors, could cause the market price of our common stock to fluctuate substantially. In addition, stock prices for many emerging growth companies fluctuate widely for reasons often unrelated to operating results. These fluctuations, as well as general economic, political and market conditions, such as recessions, interest rates, world events, military conflicts or market-sector declines, may materially and adversely affect the market price of our common stock. Any information concerning us, including projections of future operating results, appearing in investment advisory publications or on-line bulletin boards, or otherwise emanating from a source other than from us, should not be relied upon as having been supplied or endorsed by us.

A change of control of our company may be discouraged, delayed or prevented by our classified board of directors, our ability to issue preferred stock, or the voting control of our principal shareholder.

Our Articles of Incorporation divide the board of directors into three classes, with three-year staggered terms. The classified board provision could increase the likelihood that, in the event an outside party acquired a controlling block of our stock, incumbent directors nevertheless would retain their positions for a substantial period, which may have the effect of discouraging, delaying or preventing a change in control. The possible impact of such discouragement, delay or prevention of takeover attempts could adversely affect the price of our common stock.

Our Articles of Incorporation also authorize the issuance of “blank check” preferred stock with such designations, rights and preferences as may be determined from time to time by the board of directors. Accordingly, the board of directors is empowered, without shareholder approval, to issue preferred stock with dividend, liquidation, conversion, voting or other rights that could adversely affect the voting power or other rights of the holders of common stock. Holders of common stock will have no preemptive rights to subscribe for a pro rata portion of any preferred stock that may be issued. If issued, the preferred stock could be utilized, under certain circumstances, as a method of discouraging, delaying or preventing a change in control. The possible impact that the issuance of preferred stock could have on a takeover attempt could adversely affect the price of the common stock. Although we have no present intention to issue any shares of preferred stock, we may do so in the future.

Zsolt Rumy, our founder and principal shareholder, owns approximately 17.7% of outstanding shares of common stock. As a result, he has and will continue to have significant voting control over our company.

Future sales of common stock could affect the price of our common stock.

No prediction can be made as to the effect, if any, that future sales of shares or the availability of shares for sale will have on the market price of our common stock prevailing from time to time. Sales of substantial amounts of common stock, or the perception that such sales might occur, could adversely affect prevailing market prices of our common stock.

We do not currently intend to pay dividends on our common stock.

We have never declared or paid any cash dividends on our common stock and do not currently intend to do so for the foreseeable future. We currently intend to invest our future earnings, if any, to fund our growth. Therefore, you are not likely to receive any dividends on your common stock for the foreseeable future.

Item 3. Legal Proceedings

Legal contingencies have a high degree of uncertainty. When losses from contingencies become estimatable and probable, reserves are established. The reserves reflect management’s estimate of the probable cost of ultimate resolution of the matters and are revised accordingly as facts and circumstances change and, ultimately, when matters are brought to closure. If any litigation matter is resolved unfavorably, the Company could incur obligations in excess of management’s estimate of the outcome, and such resolution could have a material adverse effect on the Company’s financial condition, results of operations or liquidity. In addition, we may incur additional legal costs in connection with pursuing and defending such actions.

The Company is exposed to various claims and legal proceedings arising out of the normal course of its business. Although there can be no assurance, in the opinion of management, the ultimate outcome of these other claims and lawsuits should not have a material adverse effect on the Company’s financial condition, results of operations or liquidity.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

OVERVIEW

The following Management’s Discussion and Analysis of Financial Condition and Results of Operations (“MD&A”) is intended to help the reader understand Zoltek, our operations and our business environment. MD&A is provided as a supplement to, and should be read in conjunction with, our Consolidated Financial Statements and the accompanying notes elsewhere in this report. This overview summarizes the MD&A, which includes the following sections:

Our Business — a general description of the key drivers that affect our business, the industry in which we operate and the strategic initiatives on which we focus.

Results of Operations — an analysis of our overall results of operations and segment results for the three fiscal years presented in our financial statements. We operate in two principal segments: carbon fiber and technical fiber. Other miscellaneous and corporate are combined into a third business segment called headquarters/other.

Liquidity and Capital Resources — an analysis of cash flows, sources and uses of cash, off-balance sheet arrangements, contractual obligations, the potential impact of currency exchange and an overview of our financial position.

Critical Accounting Estimates — a description of accounting estimates that require critical judgments and estimates.

OUR BUSINESS

EXECUTIVE OVERVIEW

We are an applied technology and advanced materials company. Our mission is to lead in the commercialization of carbon fiber through our development of a price-competitive, high-performance reinforcement for composites used in a broad range of commercial products which we sell under the Panex^® trade name. In addition to manufacturing carbon fiber, we produce an intermediate product that we refer to as technical fiber, a stabilized and oxidized acrylic fiber used in flame- and heat-resistant applications which we sell under the Pyron^® trade name. We have spent over 15 years developing our proprietary technology and manufacturing processes. We believe that we are the largest capacity manufacturer primarily focused on producing low-cost carbon fiber for commercial applications.

KEY PERFORMANCE INDICATORS

Our management monitors and analyzes several key performance indicators within each of these segments to manage our business and evaluate our financial and operating performance, including:

Revenue. In the short-term, management closely reviews the volume of product shipments and indicated customer requirements in order to forecast revenue and cash receipts. In the longer-term, management believes that revenue growth through sales to new customers in existing applications and new product applications are the best indicator of whether we are achieving our objective of commercializing carbon fiber. We expect that new applications, including those we are attempting to facilitate, will continue to positively affect demand for our products.

Gross profit. Our total gross margin for fiscal 2010, 2009, and 2008 was 10.3%, 22.1% and 27.6%, respectively. Management focuses on maintaining and improving the gross profit over the long-term while leading the commercialization of carbon fiber and controlling associated costs. As such, the Company has maintained available unused capacity to remain poised to capture opportunities in emerging markets. Gross margin was negatively impacted by 10.0% by available unused capacity costs of $12.8 million in fiscal 2010. The primary cost components of our carbon fiber and technical fiber segments are ACN, which is a propylene-based product and our primary raw material for the production of acrylic fiber precursor used in our carbon fiber and technical fiber production and energy. Unscheduled shutdowns of ACN production in Europe coupled with an increase in demand for ACN drove prices up more than 100% during fiscal 2010 which placed additional pressure on our gross margins during the year.

Operating expenses. Our operating expenses are driven by headcount and related administrative costs, marketing costs and research and development costs. We monitor headcount levels in specific geographic and operational areas. We believe that research and development expenditures will be the primary means by which we can facilitate new product applications.

Cash flow from operating activities. Cash flow from operating activities for fiscal 2010, 2009, and 2008 was $22.0 million, $15.2 million, and $20.2 million. Management believes that operating cash flow is meaningful to investors because it provides a view of Zoltek with respect to sustainability of our ongoing operations and the extent to which we may or may not require external capital. It also provides meaningful insight into the management of our working capital.

Liquidity and cash flows. Due to the variability in revenue, our cash position varies. We closely monitor our expected cash levels, particularly as they relate to operating cash flow, days’ sales outstanding, days’ payables outstanding and inventory turnover. Management aggressively pursues any late receivables and actively manages its inventory levels in order to effectively use it, working capital. Management also monitors debt levels and the financing costs associated with debt. As of September 30, 2010, we had no long-term borrowings, although we do maintain lines of credit.

BUSINESS TRENDS

At the end of fiscal 2008, we completed our expansion plans and essentially doubled our production capacity over the immediately preceding two fiscal years. Our capacity increase was completed just as world trade dropped and the global economy began to experience deep recession. During fiscal 2009 and fiscal 2010, we experienced a sudden, but we believe only temporary, slowdown in the growth of the wind turbine business. This slowdown occurred at the same time as a significant decrease in the aerospace market due to unexpected delays in the introduction of new jetliners utilizing aerospace carbon fibers. Inasmuch as producers of carbon fibers for commercial and aerospace applications had greatly increased their installed capacity over the past few years, we have seen intensified competition between aerospace and commercial carbon fiber manufacturers in cross-over applications (e.g., sporting goods) for which either aerospace or commercial carbon fibers may be utilized. In this business environment, management continued to focus its efforts on building on the long-term vision of Zoltek as the leader in commercialization of carbon fibers as a low-cost but high performance reinforcement for composites. Management primarily emphasized the following areas:

	•		Increased Sales Efforts in Selected International Markets. We have identified international markets with high growth potential for our existing and emerging commercial applications. Accordingly, we have added sales personnel and increased our marketing efforts in India, China, and Korea.
	•		Business Development in Emerging Applications. We have identified emerging applications for our products with high growth potential across a variety of industries and regions. In addition to producing carbon fibers for the existing prepreg technology used by our large wind turbine customers, we have recently begun shipments of carbon fibers qualified for use in the infusion process utilized by other wind turbine blade manufacturers. We also are seeking to qualify our products for use in aerospace secondary structures such as floor, luggage bins and seats, and anticipate increased sales in this market as the production of new jetliners increases.
	•		Operating Cash Flows and Cash Management. Despite a 7.4% decrease in sales, we had positive operating cash flows of $22.0 million in fiscal 2010 compared to $15.2 million in fiscal 2009. Reduced inventory levels provided cash of $8.8 million in fiscal 2010. The Company paid down the remaining outstanding balance of $4.2 million of its convertible debt and reported $4.4 million of capital expenditures during fiscal 2010.
	•		High Raw Material Cost for Fiscal 2010. Unscheduled production shutdowns in Europe of our primary raw material, ACN, coupled with an increase in demand for ACN drove market prices up more than 100% and negatively impacted gross margins.

The Company’s sales decreased 7.4%, or $10.3 million, to $128.5 million in fiscal 2010 from $138.8 million in fiscal 2009. Sales volume to our largest customer declined by $24.7 million as demand for their wind turbines declined and they moved to just-in-time inventory. This reduction was, however, offset partially by an increase in volume of sales to other wind energy customers and other markets. Certain price reductions related to market pressures caused a $9.1 million decrease in sales compared to fiscal 2010. Carbon fiber sales decreased 10.4%, or $12.0 million, to $103.4 million during fiscal 2010 from $115.3 million during fiscal 2009. Technical fiber sales increased 11.0%, or $2.3 million, to $23.3 million during fiscal 2010 from $21.0 million during fiscal 2009. Technical fiber sales increased in fiscal 2010 primarily due to increased shipments to aircraft brake customers. Sales of other products and services consisting primarily of energy utility services provided to the local community by our Hungarian subsidiary decreased $0.6 million to $1.8 million during fiscal 2010 from $2.4 million during fiscal 2009.

The Company’s cost of sales increased by 6.5% or $7.1 million, to $115.2 million during fiscal 2010 from $108.1 million during fiscal 2009. Our raw material costs increased substantially as unscheduled shutdowns of ACN production in Europe coupled with an increase in demand for ACN drove market prices up more than 100% by the end of fiscal 2010. Carbon fiber cost of sales increased by 7.0%, or $6.2 million, to $94.9 million during fiscal 2010 from $88.7 million for fiscal 2009 as a result of the increase in raw material costs and unscheduled shutdowns described above. Technical fiber cost of sales increased $1.7 million, or 9.8%, to $19.1 million for fiscal 2010 from $17.4 million for fiscal 2009 primarily as a result of the increased sales noted above. The cost of sales of the corporate/other products segment decreased by 41.0%, or $0.8 million to $1.2 million for fiscal 2010 as compared to $2.1 million for fiscal 2009.

Included in the Company’s cost of sales were available unused capacity costs of $12.8 million. These costs are comprised of fixed production costs allocated to manufacturing lines which were producing below normal levels and amounted to $11.9 million for the carbon fiber segment and $0.9 million for the technical fiber segment during fiscal 2010. The Company believes maintaining this available unused capacity has been necessary to encourage development of significant large-scale applications and maintain a level of readiness as we anticipate a return to more robust market conditions. The cost of sales of other products decreased for fiscal 2010 to $1.2 million compared to fiscal 2009 of $2.1 million.

The Company’s gross profit decreased by 56.6%, or $17.4 million, to $13.3 million during fiscal 2010 from $30.6 million in fiscal 2009. Carbon fiber gross profit percentage decreased to 8.2% for fiscal 2010 compared to 23.1% for fiscal 2009. Carbon fiber gross profit decreased from $26.7 million to $8.5 million during these respective periods. The decreases in carbon fiber gross profit and gross profit percentage resulted primarily from available unused capacity costs expensed during the fiscal year and price reductions discussed above. Our raw material costs increased substantially as unscheduled shutdowns of ACN production in Europe coupled with an increase in demand for acrylonitrile (ACN) drove market prices up more than 100% by the end of fiscal 2010. Additional decreases in carbon fiber gross profit and gross profit margin resulted from available unused capacity costs expensed during the year compared to fiscal 2009. Technical fiber gross profit increased from $3.6 million, or 17.3% of sales, for fiscal 2009 to $4.2 million, or 18.2% of sales, during fiscal 2010. The increases in technical fiber gross profit and margin resulted from favorable product sales mix. The gross profit of the other products increased for fiscal 2010 to $0.6 million compared to a gross profit for fiscal 2009 of $0.4 million.

Application and market development costs were $8.2 million in fiscal 2010 and $7.6 million in fiscal 2009. These costs included product and market development efforts, product trials and product development personnel costs. Targeted emerging applications include automobile components, offshore oil and gas drilling, fire/heat barrier and alternate energy technologies. The increase from fiscal 2009 to fiscal 2010 is primarily due to increased focus on developing new production methods that will enable potential automotive customers to fabricate cost-effective carbon fiber intermediate products.

Selling, general and administrative expenses decreased by $3.8 million, to $15.6 million in fiscal 2010 from $19.4 million in fiscal 2009. The Company recorded $2.0 million for the cost of employee and director services received in exchange for equity instruments during fiscal 2010, a decrease of $1.0 million from $3.0 million in fiscal 2009. Additionally, the decrease was due to a decrease of $0.4 million in legal fees, $0.8 million decrease in bad debt expense and $0.2 million decrease in audit and tax fees. During fiscal 2010, the Company realigned its organizational structure, assigning some management personnel from administrative roles to better focus on operations.

There were no litigation related charges in fiscal 2010 compared to $0.2 million in fiscal 2009. The 2009 charges related to the affirmance of the judgment in the supply agreement litigation (see Note 8 of the Notes to Consolidated Financial Statements).

Operating loss was $10.6 million for fiscal 2010 compared to income of $3.4 million in fiscal 2009. Carbon fiber operations reported operating income of $0.3 million for fiscal 2010 compared to income of $14.2 million in fiscal 2009. The decrease in operating income in the carbon fiber operation in fiscal 2010 related to the decrease in production and sales, as well as the cost factors mentioned above. Operating income from technical fibers increased $1.1 million, from $2.3 million for fiscal 2009 to $3.4 million for fiscal 2010. Corporate headquarters/other reported an operating loss of $14.3 million for fiscal 2010 compared to a loss of $13.1 million during fiscal 2009 due to increases in application and development and selling, general, and administrative costs as discussed.

Interest expense, net, was $0.3 million for fiscal 2010, compared to $1.0 million in fiscal 2009. The decrease in interest expense, net, resulted from the repayment of debt during fiscal 2010.

Amortization of financing fees, which are non-cash expenses, was approximately $0.3 million during fiscal 2010 compared to $5.4 million during fiscal 2009. (See “Liquidity and Capital Resources Financing”).

Gain (loss) on foreign currency transactions was a gain of $1.9 million for fiscal 2010 compared to a gain of $2.2 million for fiscal 2009. During fiscal 2010, the Euro and the U.S. dollar gained in value against the HUF. As most of the Company’s accounts receivables are denominated in Euros, the strengthening value over fiscal 2010 resulted in a gain recognized in our Hungarian subsidiary. This gain during fiscal 2010 was offset by currency losses incurred related to US dollar-denominated intercompany payables; however, an overall gain was recognized. The translation of the Hungarian subsidiary’s financial statements from its functional currency (HUF) to U.S. dollars is not included in determining net income for the period but is recorded in accumulated other comprehensive loss in equity.

Other expense, net, was $0.7 million in fiscal 2010 compared to $1.2 million for fiscal 2009. Other expense, net consists primarily of loss from the sale of miscellaneous equipment and from miscellaneous fees in Hungary.

Gain on derivative liabilities was $1.8 million at the end of fiscal 2010 due to the adoption of ASC 815 (see “— Liquidity and Capital Resources — Derivative Instruments and Fair Value Measurements”).

Income tax benefit was $1.8 million for fiscal 2010 compared to expense of $2.1 million for fiscal 2009. During fiscal 2010, income tax expense of $0.8 million was incurred related to the local Hungarian municipality tax. This expense was offset by the release of the $2.2 million reserve on the Company’s uncertain tax positions due to a favorable resolution with the Hungarian Tax Authority. An additional income tax benefit of $0.7 million was recorded during fiscal 2010 related to the net operating loss for the Hungarian subsidiary. Local and federal alternative minimum taxes in the U.S. and Mexico were $0.2 million.

The foregoing resulted in a net loss of $6.3 million for fiscal 2010 compared to $4.2 million for fiscal 2009. Similarly, the Company reported net loss per share of $0.18 and $0.12 on a basic and diluted basis for fiscal 2010 and 2009, respectively. The weighted average basic common shares outstanding were 34.4 million for both fiscal 2010 and 2009.

FISCAL YEAR ENDED SEPTEMBER 30, 2009 COMPARED TO FISCAL YEAR ENDED SEPTEMBER 30, 2008

The Company’s sales decreased 25.2%, or $46.9 million, to $138.8 million in fiscal 2009 from $185.6 million in fiscal 2008. The decline in revenue was primarily due to declined sales volume, pricing declines resulting from significant cost reduction in raw materials and energy and currency fluctuation, and the weakness of the Euro versus the U.S. dollar during fiscal 2009. During fiscal 2009, there was approximately a 14.5% decrease in volume of product shipments as compared to 2008, which accounted for approximately $20.9 million of the revenue decrease. Certain price reductions resulted from passing on raw material cost savings to customers, which caused an $11.6 million decrease in sales over fiscal 2009. The majority of our European sales are denominated in Euros, which weakened significantly versus the U.S. dollar during most of the 2009 fiscal year, causing approximately $8.9 million of the decrease in sales. Carbon fiber sales decreased 26.1%, or $40.7 million, to $115.3 million during fiscal 2009 from $156.0 million during fiscal 2008. Technical fiber sales decreased 19.0%, or $4.9 million, to $21.0 million during fiscal 2009 from $25.9 million during fiscal 2008. Technical fiber sales decreased in fiscal 2009 primarily due to lower shipments to aircraft brake customers. Sales of other products and services consisting primarily of energy utility services provided to the local community by our Hungarian subsidiary decreased $1.3 million to $2.4 million during fiscal 2009 from $3.7 million during fiscal 2008.

The Company’s cost of sales decreased by 19.6%, or $26.3 million, to $108.1 million during fiscal 2009 from $134.4 million during fiscal 2008. Carbon fiber cost of sales decreased by 19.9%, or $22.0 million, to $88.7 million during fiscal 2009 from $110.7 million for fiscal 2008. The decrease in carbon fiber cost of sales reflected decreased sales of 26.2% discussed above. Technical fiber cost of sales decreased $3.0 million, or 14.8%, to $17.4 million for fiscal 2009 from $20.4 million for fiscal 2008 primarily as a result of the decreased sales noted above. Included in the Company’s cost of sales were available unused capacity costs of $7.4 million. These costs are comprised of fixed production costs allocated to manufacturing lines which were producing below normal levels and amounted to $6.4 million for the carbon fiber segment and $1.0 million for the technical fiber segment during fiscal 2009. The Company believes maintaining this available unused capacity has been necessary to encourage development of significant large-scale applications and maintain a level of readiness as we anticipate a return to more robust market conditions. The cost of sales of other products decreased for fiscal 2009 to $2.1 million compared to fiscal 2008 of $3.3 million.

The Company’s gross profit decreased by 40.1%, or $20.6 million, to $30.6 million during fiscal 2009 from $51.2 million in fiscal 2008. Carbon fiber gross profit percentage decreased to 23.1% for fiscal 2009 compared to 29.1% for fiscal 2008. Carbon fiber gross profit decreased from $45.3 million to $26.7 million during these respective periods. The decreases in carbon fiber gross profit and gross profit percentage resulted primarily due to available unused capacity costs expensed during the fiscal year. Technical fiber gross profit decreased from $5.5 million, or 21.4% of sales, for fiscal 2008 to $3.6 million, or 17.3% of sales, during fiscal 2009. The decrease in technical fiber gross profit and gross profit percentage resulted primarily from available unused capacity costs expensed during the fiscal year and decreased shipments to the primary aircraft brake customers. The gross profit of the other products increased for fiscal 2009 to $0.4 million compared to a gross profit for fiscal 2008 of $0.3 million.

Application and market development costs were $7.6 million in fiscal 2009 and $8.1 million in fiscal 2008. These costs included product and market development efforts, product trials and product development personnel costs. Targeted emerging applications include automobile components, offshore oil and gas drilling, fire/heat barrier and alternate energy technologies. These costs include expenses associated with application development of the towpreg product at the Company’s prepreg facility in Utah.

A litigation charge of $0.2 million was recorded in fiscal 2009 related to the affirmance of the judgment in the SP case compared to a charge of $4.9 million during fiscal 2008 (see Note 8 of the Notes to Consolidated Financial Statements).

Selling, general and administrative expenses increased by $1.2 million, to $19.4 million in fiscal 2009 from $18.2 million in fiscal 2008. The Company recorded $3.0 million for the cost of employee and director services received in exchange for equity instruments under FASB ASC 715 (formerly referenced as Statement of Financial Accounting Standards (SFAS) 123-R “Share-Based Payments”) during fiscal 2009 and $2.3 million in fiscal 2008. The increase was due to the true-up of the employee forfeiture rate as the retention rate for top management improved significantly from historical averages. Administrative costs in Mexico increased by approximately $1.0 million as the plant built up staffing to prepare for operations. The Company spent $0.4 million in fiscal 2008 related to a previously disclosed accounting investigation. There was a $0.1 decrease in expenses related to a supersedeas bond related to a judgment in litigation related to supply agreement (see Note 8 to the Notes to Consolidated Financial Statements).

Operating income was $3.4 million for fiscal 2009 compared to income of $20.0 million in fiscal 2008. Carbon fiber operations reported operating income of $14.2 million for fiscal 2009 compared to income of $34.0 million in fiscal 2008. The decrease in operating income in the carbon fiber operation in fiscal 2009 related to the decrease in production and sales, as well as the other factors mentioned above. Operating income from technical fibers decreased $0.7 million, from $3.0 million for fiscal 2008 to $2.3 million for fiscal 2009, as sales decreased $4.9 million due to decreased orders from aircraft brake customers. Corporate headquarters/other reported an operating loss of $13.1 million for fiscal 2009 compared to a loss of $17.0 million during fiscal 2008. The decrease in operating loss was due primarily to the decrease in legal and litigation expenses due to the resolution of certain lawsuits during 2009.

Interest expense was $1.4 million for fiscal 2009, compared to $1.9 million in fiscal 2008. The decrease in interest expense resulted from the repayment of $10.5 million and conversion of $0.3 million of convertible debt to common stock during fiscal 2009.

Amortization of financing fees, which are non-cash expenses, was approximately $5.4 million during fiscal 2009 compared to $6.7 million during fiscal 2008. (See “Liquidity and Capital Resources Financing Activity”).

Interest income was $0.4 million for fiscal 2009 compared to $2.9 million for fiscal 2008. The decrease was a result of lower cash balance on hand.

Gain on foreign currency transactions improved to $2.2 million for fiscal 2009 compared to a loss of $0.4 million for fiscal 2008. During fiscal 2009, the Hungarian Forint (“HUF”) weakened in value against the Euro and the U.S. dollar, causing a loss on the Company’s accounts receivable, but was offset by a gain on a large U.S. dollar denominated intercompany payable. The translation of the Hungarian subsidiary’s financial statements from its functional currency (HUF) to U.S. dollars is not included in determining net income for the period but is recorded in accumulated other comprehensive income (loss) in equity.

Other expense, net, was $1.2 million in fiscal 2009 compared to $1.1 million for fiscal 2008. Other expense, net for fiscal 2009 consisted primarily of loss from the sale of miscellaneous equipment and from miscellaneous penalties and fees in Hungary.

Income tax expense was $2.1 million for fiscal 2009 compared to $5.4 million for fiscal 2008 due primarily to decreased sales and taxable income generated in Hungary. An additional income tax expense of $1.2 million was recorded for fiscal 2008 as the Company accrued for a special Hungarian tax of 4% on pre-tax net income. In fiscal 2009, this special Hungarian tax did not apply to the Company. The Company accrued approximately $0.2 million in alternative minimum and local income taxes in the U.S. and Mexico.

The foregoing resulted in loss from continuing operations of $4.2 million for fiscal 2009 compared to a net income of $7.4 million for fiscal 2008. Similarly, the Company reported net loss from continuing operations per share of $0.12 on a basic and diluted basis for fiscal 2009 and net income from continuing operations per share of $0.22 on a basic and diluted basis for fiscal 2008. The weighted average basic common shares outstanding were 34.4 million and 34.0 million for fiscal 2009 and 2008, respectively.

LIQUIDITY AND CAPITAL RESOURCES

The Company believes its cash currently on hand, cash flow from operations and available credit facilities should be sufficient to fund its identified liquidity needs over the next twelve months.

CASH FLOWS

Cash Provided By Operating Activities

Operating activities provided $22.0 million of cash for fiscal 2010. Reduction of inventory levels provided $8.8 million during fiscal 2010 due to lower production, coupled with sales of existing inventory. Cash flows were positively affected by depreciation of $16.5 million in 2010, which was included in the operating loss of $10.6 million. Cash flows were positively impacted by $5.4 million as accounts receivables decreased due to decrease sales levels and collection activities and $2.2 million as accrued expenses and other liabilities increased during fiscal 2010.

Operating activities provided $15.2 million of cash for fiscal 2009. Cash flows were positively affected by operating income before depreciation of $19.7 million. Cash flows were negatively affected during fiscal 2009 by the payment of $5.6 million, net of accrued interest, to resolve litigation involving an investment banker (see Note 8 of the Notes to Consolidated Financial Statements). In February 2009, the Company used $23.5 million of restricted cash to resolve litigation involving a supply agreement. Restricted cash has been shown as a use of cash in investing activities during fiscal 2008, 2007 and 2006, so its usage in 2009 had no impact on unrestricted cash balances. Increased inventory levels used $4.3 million of cash in the current fiscal year. Collections from accounts receivable resulted in a net increase in cash flow of $8.5 million.

Cash Used In and Provided By Investing Activities

Net cash used in investing activities for fiscal 2010 was $4.1 million, which consisted of capital expenditures on existing production lines and new equipment. This included $0.1 million of funds received from the Hungarian government as a conditional grant to reimburse capital expenditures and related outlays (see Note 2 of the Notes to Consolidated Financial Statements).

Net cash used in investing activities for fiscal 2009 was $20.5 million, which consisted of capital expenditures to expand production lines of the Company’s precursor facilities and carbon fiber operations to meet the anticipated long-term demand for carbon fiber products. This included $1.6 million of funds received from the Hungarian government as a conditional grant to reimburse capital expenditures and related outlays (see Note 2 of the Notes to Consolidated Financial Statements).

Cash Used and Provided In Financing Activities

Net cash used in financing activities was $16.8 million in fiscal 2010 consisting primarily of the repayment of convertible debt and lines of credit.

Net cash used in financing activities was $3.0 million in fiscal 2009 as the Company repaid convertible debt of $10.6 million, which was offset by increasing borrowings on our lines of credit by $7.6 million.

HUNGARIAN GRANT

The Hungarian government has pledged a grant of 2.9 billion HUF to Zoltek’s Hungarian subsidiary that will provide a portion of the capital resources to modernize its facility, establish a research and development center, and support buildup of manufacturing capacity of carbon fibers. Zoltek’s Hungarian subsidiary received approximately HUF 0.1 billion, HUF 0.3 billion, and HUF 0.7 billion in grant funding during fiscal 2010, 2009, and 2008, respectively. These funds have been recorded as a liability on the Company’s consolidated balance sheet. The liability will be amortized over the life of the assets procured by the grant funds, offsetting the depreciation expense of the assets into which the proceeds of the grant are invested. The Company has presented bank guarantees amounting to 120% of the amount of the grant as received.

The Hungarian subsidiary may be required to pay back all or a portion of the grant if, among other things, the Hungarian subsidiary: fails to obtain revenue targets; fails to employ an average annual staff of at least 1,200 employees; fails to utilize regional suppliers for at least 45% of its purchases; fails to obtain consent from the Hungarian government prior to selling assets created with grant funds; fails to use grant funds in accordance with the grant agreement; fails to provide appropriate security for the grant; makes or made an untrue statement or supplies or supplied false data in the grant agreement, grant application or during the time of the grant; defaults on its obligations by more than 30 days; withdraws any consents it gave in the grant agreement; or causes a partial or complete failure or hindrance of the project that is the subject of the grant. These targets must be achieved during a five-year measurement period from October 2012 to October 2017. Although there can be no assurance, the Company anticipates it will comply with the requirements of the grant agreement when the measurement period begins.

FINANCING ACTIVITY

Revolving Credit Facility

In February 2010, the Company extended its existing U.S. line of credit until January 1, 2011. The revolving credit facility has a total commitment of the lesser of (1) $10.0 million or (2) an eligible borrowing base equal to a percentage of eligible accounts receivable plus a percentage of eligible inventories, which as of September 30, 2010 equaled $10.0 million. There were no borrowings under the facility as of September 30, 2010.

In August 2010, the Company’s Hungarian subsidiary extended its existing line of credit until August 30, 2011. The revolving credit facility has a total commitment of the lesser of 1.9 billion HUF or a borrowing base, which as of September 30, 2010 was $9.5 million. There were no borrowings under this credit facility at September 30, 2010. The credit facility is a term loan with quarterly interest payments.

The Company intends to extend its existing lines of credit before expiration. Based on the history of relationships with its banks and its current financial position, the Company expects it will be able to successfully extend its lines of credit.

Bond Related to Litigation

In April 2007, the Company reported the results of various post-trial motions in ongoing litigation (see Note 8 of the Notes to the Consolidated Financial Statements). In April 2007 the Company posted a supersedeas bond, collateralized by a $23.5 million letter of credit issued by the Company’s U.S. bank. As of September 30, 2008, the letter of credit was collateralized by $23.5 million of restricted cash.

On February 9, 2009, the Company paid the judgment using $23.5 million of restricted cash, which terminated the letter of credit and related bond.

Convertible Debt

In September 2005, Zoltek entered into an agreement for new financing; a convertible debenture package of up to $50 million in a private placement with a group of institutional investors.

In April 2010, the Company repaid all remaining convertible debt with cash on hand. There was no conversion of convertible debt during fiscal 2010. The following tables summarize the activity regarding our convertible debt conversions during the fiscal years ended 2009.

Amortization of Financing Fees and Debt Discount

Convertible debt issued in May 2006, July 2006 and October 2006 was considered to have beneficial conversion features because the adjusted conversion price after allocating a portion of the proceeds to the warrants issued in connection with the convertible debt was less than the market price of the Company’s common stock at date of issue. The beneficial conversion was recorded as a reduction in the carrying value of the convertible debt security and accreted to its face value over the life of the convertible security and expensed into the Company’s income statement. If the convertible security was converted prior to the redemption date, the unamortized balance was recorded in expense at the time of conversion.

At the time of issuance of convertible debt securities with warrants, the Company recorded the fair value associated with the warrants using the Black-Scholes option-pricing model. This fair value discount was recorded as a reduction in the carrying value of the convertible debt security that was accreted to its face value over the life of the convertible security and expensed into the Company’s income statement. If the convertible security was converted prior to the redemption date, the unamortized debt discount associated with the valuation of the warrants was recorded as a reduction to additional paid-in capital at the time of conversion.

The tables below show the impact of amortization of financing fees and debt discount on the financial results for the fiscal years ended September 30, 2010, 2009 and 2008 (in thousands).

EARNINGS PER SHARE

In accordance with ASC 260, the Company has evaluated its diluted income per share calculation. The Company does have outstanding warrants at September 30, 2010 and outstanding warrants and convertible debt at September 30, 2009 and 2008 which are not included in the determination of diluted loss per share for the fiscal years ended September 30, 2010, 2009 and 2008 because the shares are anti-dilutive. Had these securities been dilutive, an additional 0.1 million, 0.3 million and 0.7 million shares, respectively, would have been included in the Company’s diluted loss per share calculation.

The following is the diluted impact of the convertible debt and warrants on net income (loss) per share for the fiscal years ended September 30, 2010, 2009 and 2008 respectively:

FUTURE CONTRACTUAL OBLIGATIONS

In the table below, we set forth our enforceable and legally binding obligations as of September 30, 2010. Some of the amounts included in this table (amounts in thousands) are based on our estimates and assumptions about these obligations, including their durations, anticipated actions by third parties and other factors. The enforceable and legally binding obligations we will actually pay in future periods may vary from those reflected in the table because the estimates and assumptions are subjective.

SUPPLY CONTRACTS

We are party to long-term supply contracts with our wind energy customers Vestas Wind Systems and Gamesa Group. Vestas was the only customer which represented greater than 10% of net sales for fiscal 2010 and 2009. In fiscal year 2010 and 2009, we reported net sales of $49.5 million and $74.2 million to Vestas Wind Systems, which represented 38.6% and 53.6%, respectively, of our net sales. In fiscal 2008, we reported net sales of $75.1 million to Vestas Wind Systems, which represented 40.4% of our net sales and $24.6 million to Gamesa Group, which represented 13.3% of our net sales. These were the only customers that represented greater than 10% of consolidated net sales during any of these three years.

Our current supply agreement with Vestas Wind Systems was executed in May 2007 and obligates us to supply carbon fibers under a five-year delivery schedule, and a rolling three-year schedule as long as the supply agreement is in place. Under the agreement, Vestas provides us with annual forecasts of its supply requirements, and we receive binding orders for shipments on approximately a monthly basis. We are not guaranteed specific levels of sales under the agreement, and we are subject to liquidated damages if we are unable to perform our obligations under the agreement. In general, the agreement may be terminated by: (1) mutual agreement of the parties, (2) by either party with at least 36 months’ written notice, (3) by either party as a result of a material breach of the agreement that is not remedied within 30 days of receipt of notice of such breach, and (4) by either party in the event of the bankruptcy, insolvency, or change of control of the other party.

Our current supply agreement with Gamesa Group was executed in July 2007 and is effective through December 31, 2012, subject to automatic renewal for successive one-year terms upon at least two years’ advance notice by Gamesa to Zoltek. The agreement obligates Zoltek to supply carbon fibers during the term of the contract provides based upon annual anticipated base volumes amounts, which are converted into binding orders for shipments on approximately a quarterly basis. We are not guaranteed specific levels of sales under the agreement, and we are subject to liquidated damages if we are unable to perform our obligations under the agreement. In general, the agreement may be terminated (1) by mutual agreement of the parties, (2) by either party with at least 36 months’ written notice, (3) by either party as a result of a material breach of the agreement that is not remedied within 45 days of receipt of notice of such breach or the bankruptcy, and (4) by either party in the event of the bankruptcy, insolvency, or change of control of the other party.

In our supply agreements with Vestas and Gamesa, we do not have post-shipment obligations other than that we warrant that our products are free from defects in design, materials, and workmanship at the time of delivery and that the products are produced in accordance with standard production and sales specifications stated in the agreements. The Vestas agreement states that the warranty shall continue for a period of five years from the date of delivery of the products. The Gamesa agreement states that all products shall, as of the moment of delivery, be warranted for three years with regards to manufacture.

LEGAL CONTINGENCIES

Legal contingencies have a high degree of uncertainty. When losses from contingencies become estimatable and probable, reserves are established. The reserves reflect management’s estimate of the probable cost of ultimate resolution of the matters and are revised accordingly as facts and circumstances change and, ultimately, when matters are brought to closure. If any litigation matter is resolved unfavorably, the Company could incur obligations in excess of management’s estimate of the outcome, and such resolution could have a material adverse effect on the Company’s consolidated financial condition, results of operations or liquidity. We anticipate that we will incur additional legal costs in connection with pursuing and defending such actions.

See Note 8 of the Notes to the Company’s Consolidated Financial Statements for a description of our significant legal matters.

CRITICAL ACCOUNTING ESTIMATES

Certain of our accounting policies require our management to make difficult, subjective or complex judgments. All of the Company’s accounting policies are in compliance with U.S. generally accepted accounting principles (“GAAP”). The Company considers the following policies to be the most critical in understanding the estimates, assumptions and judgments that are involved in preparing our financial statements, and the uncertainties that could affect our results of operations, financial condition and cash flows.

ACCOUNTS RECEIVABLE COLLECTIBILITY

The Company evaluates the collectability of our accounts receivable for each of our segments based on a combination of factors. In circumstances where we are aware of a specific customer’s inability to meet its financial obligations to us (e.g., bankruptcy filing or substantial downgrading of credit), we record a specific reserve for bad debts against the amounts due reducing the net recognized receivable to the amount we estimate will be collected. For all other customers, we estimate reserves for bad debts based on the length of time receivables have been past due and our experience with collection. Our bad debt expense on accounts receivable was $0.5 million for fiscal 2010, $1.3 million for fiscal 2009 and $1.3 million for fiscal 2008.

INVENTORIES

The Company evaluates its ending inventories for estimated excess quantities and obsolescence. This evaluation includes analyses of sales levels by product and projections of future demand within specific time horizons. Inventories in excess of future demand, if any, are reserved. Remaining inventory balances are adjusted to approximate the lower of cost on a first-in, first-out basis or market value. Cost includes material, labor and overhead. If future demand or market conditions are less favorable than the Company’s projections, additional inventory write-downs may be required and would be reflected in cost of sales on the Company’s statement of operations in the period in which the revision is made.

The Company historically has not experienced material problems related to the pricing or functionality of carbon fibers inventory. Our PanexÒ carbon fibers represent the majority of our inventory balance and are available in continuous tow, fabric, prepreg, chopped, and milled forms. Generally, technical obsolescence and spoilage have not historically been a concern because nonqualifying produced items can be reclaimed for processing for sale in secondary markets.

Available unused capacity costs for fiscal 2010 were comprised of fixed production costs allocated to manufacturing lines which were producing below normal levels during the year. The Company reviews monthly production levels of all manufacturing lines for all products. Any lines which produced at a rate below a historical range of normal capacity were identified and the fixed costs associated with those lines were calculated. The unallocated costs were recognized as an expense in the period in which they were incurred.

VALUATION OF LONG-LIVED ASSETS

Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. Zoltek management is responsible for routinely assessing whether impairment indicators are present. The Company expects that the components of each operating segment will exhibit similar financial performance over the long term and, therefore, groups assets accordingly for analyzing whether impairment exists. If the sum of the expected future undiscounted cash flows is less than the carrying amount of the asset group, a loss is recognized for the difference between the fair value and the carrying value of the asset group. In determining expected future undiscounted cash flows attributable to the group of long-lived assets, the Company must make certain judgments and estimations including the expected market conditions and demand for products produced by the assets, expected product pricing assumptions, and assumptions related to the expected costs to operate the assets. It is possible that actual future cash flows related to the Company’s long-lived assets may materially differ from the Company’s determination of expected future undiscounted cash flows. Additionally, if the Company’s expected future undiscounted cash flows were less than the carrying amount of the asset group being analyzed, it would be necessary for the Company to make significant judgments regarding the fair value of the asset due to the specialized nature of much of the Company’s carbon fiber production equipment in order to determine the amount of the impairment charge.

CONTINGENT LIABILITIES

The Company is subject to lawsuits, investigations, and other claims related to employment, environmental, service providers, supply agreements, taxing authorities, and other matters, and is required to assess the likelihood of any adverse judgments or outcomes to these matters, as well as potential ranges of probable losses. A determination of the amount of reserves and disclosures required, if any, for these contingencies is made after considerable analysis of each individual issue. We accrue for contingent liabilities when an assessment of the risk of loss is probable and can be reasonably estimated.

Our contingent liabilities contain uncertainties because the eventual outcome will result from future events, and determination of current reserves requires estimates and judgments related to future changes in facts and circumstances, differing interpretations of the law and assessments of the amount of damages, and the effectiveness of strategies or other factors beyond our control. However, if actual results are not consistent with our estimates or assumptions, we may be exposed to gains or losses that could be material.

INCOME TAXES

The Company accounts for certain income and expense items differently for financial reporting and income tax purposes. Deferred tax assets and liabilities are determined based on the difference between the financial statement and tax basis of assets and liabilities applying enacted statutory tax rates in effect for the year in which the differences are expected to reverse. A valuation allowance is provided against certain deferred tax assets when realization of those assets are not considered to be more likely than not.

We are subject to the jurisdiction of numerous tax authorities. Our operations in these different jurisdictions are generally taxed on income before taxes adjusted for various differences between tax law and GAAP accounting. Determination of taxable income in any jurisdiction requires the interpretation of the related tax laws and regulations and the use of estimates and assumptions regarding significant future events such as the amount, timing and character of deductions, permissible revenue recognition methods under the tax law and the sources and character of income and tax credits. Changes in tax laws, regulations, agreements and treaties, foreign currency exchange restrictions or our level of operations or profitability in each taxing jurisdiction could have an impact on the amount of income taxes that we provide during any given year. Our tax filings for various periods are subject to audit by the tax authorities in the jurisdictions in which we conduct business.

STOCK-BASED COMPENSATION

On October 1, 2005, the Company adopted the provisions of ASC 718, using the modified prospective method.ASC 718 requires companies to recognize the cost of employee services received in exchange for awards of equity instruments based upon the grant date fair value of those awards. Under the modified prospective method of adopting ASC 718 the Company recognized compensation cost for all share-based payments granted after October 1, 2005, plus any awards granted to employees prior to October 1, 2005 that remain unvested at that time. Under this method of adoption, no restatement of prior periods was made. The Company uses historical volatility for a period of time that is comparable to the expected life of the option. However, the Company only calculates the volatility of the Company’s stock back to November 2003, the date the Company received its first large order for carbon fiber, as that is when the Company considers its business to have changed from a research and development company to an operational company. Management believes this is a better measurement of the Company’s stock volatility.

RECENT ACCOUNTING PRONOUNCEMENTS

See Note 1 of the Notes to the Company’s Consolidated Financial Statements.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

Foreign Currency Risk

The consolidated balance sheets of the Company’s international subsidiaries, Zoltek Zrt. and Zoltek de Mexico, were translated from Hungarian Forints and Mexican Pesos to U.S. dollars, respectively, at the exchange rate in effect at the applicable balance sheet date, while its consolidated statements of operations were translated using the average exchange rates in effect for the periods presented. The related translation adjustments are reported as other comprehensive income (loss) within shareholders’ equity. Gains and losses from foreign currency transactions of Zoltek Zrt. are included in the results of operations in other expenses. The Company views as long-term its investments in Zoltek Zrt. and Zoltek de Mexico. Zoltek Zrt. Has a functional currency of the HUF. As a result, the Company is exposed to foreign currency risks related to this investment. The functional currency of Zoltek de Mexico has changed as of November 1, 2008 from the Mexican Peso to the U.S. dollar. The Company does not currently employ a foreign currency hedging strategy related to the sales from Hungary or Mexico. Neither Hungary nor Mexico is considered to be a highly inflationary or deflationary economy.

As of September 30, 2010, the Company had a long-term loan to its Zoltek Zrt. subsidiary of $108 million denominated in U.S. dollars. The potential loss in value of the Company’s net foreign currency investment in Zoltek Zrt. resulting from a hypothetical 10% adverse change in quoted foreign currency exchange rate of the HUF against the U.S. dollar at September 30, 2010 and 2009 amounted to $10.8 million and $10.8 million, respectively. The Company does not expect repayment of the loan in the foreseeable future. As such, the Company considers this loan as a permanent investment. In addition, Zoltek Zrt. routinely sells its products to customers located primarily throughout Europe in sales transactions that are denominated in foreign currencies other than the HUF. Also, Zoltek Zrt. has debt that is denominated in foreign currencies other than the HUF.

As of September 30, 2010, the Company had a long-term loan to its Zoltek de Mexico subsidiary. There is no potential loss in value of the Company’s net foreign currency investment in Zoltek de Mexico resulting from an adverse change in quoted foreign currency exchange rate of the Mexican Peso against the U.S. dollar at September 30, 2010 because Zoltek de Mexico’s functional currency is the U.S. dollar. The Company does not expect repayment of the loan in the foreseeable future. As such, the Company considers this loan as a permanent investment.

Commodity Price Risk

We are exposed to commodity price risk arising from changes in the market price of certain raw materials, such as ACN, and utilities. Due to competition and market conditions, volatile price increases cannot always be passed on to our customers. Management assesses commodity price trends on a regular basis and adjusts purchasing accordingly. The Company does not currently utilize derivative instruments to hedge purchases of commodities.

Interest Rate Risk

The Company is exposed to changes in interest rates primarily as a result of borrowing activities under its credit facility and other variable rate debt. As of September 30, 2010, the Company had borrowings of $1.0 million. At variable rates and a two-percentage point change in the average interest rate under these borrowings, it is estimated our interest expense for the twelve months ended September 30, 2010 would have changed by approximately $0.02 million. In the event of an adverse change in interest rates, we would seek to take actions to mitigate our exposure to interest rate risk. Further, no consideration has been given to the effects of the change in the level of overall economic activity that could exist in such an environment. The nature and amount of the Company’s debt may vary as a result of future business requirements, market conditions and other factors. The extent of the Company’s interest rate risk is not quantifiable or predictable because of the variability of future interest rates and business financing requirements. The Company does not believe such risk is material because of the Company’s relatively low debt and because a significant amount of the Company’s current debt is at fixed rates. At September 30, 2010, the Company did not have any interest rate swap agreements outstanding.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Shareholders of Zoltek Companies, Inc.

We have audited Zoltek Companies, Inc.’s internal control over financial reporting as of September 30, 2010, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (the COSO criteria). Zoltek Companies, Inc.’s management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the company’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, Zoltek Companies, Inc. maintained, in all material respects, effective internal control over financial reporting as of September 30, 2010, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheet of Zoltek Companies, Inc. as of September 30, 2010 and 2009, and the related consolidated statements of operations, shareholders’ equity, and cash flows for the years then ended of Zoltek Companies Inc. and our report dated November 29, 2010 expressed an unqualified opinion thereon.

ZOLTEK COMPANIES, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

ORGANIZATION AND PRINCIPLES OF CONSOLIDATION

Zoltek Companies, Inc. is a holding company, which operates through wholly-owned subsidiaries, Zoltek Corporation, Zoltek Zrt., Zoltek de Mexico SA de CV, Zoltek de Occidente SA de CV, Engineering Technology Corporation (“Entec Composite Machines”), Zoltek Properties, Inc., and Zoltek Automotive, LLC. Zoltek Corporation (“Zoltek”) develops, manufactures and markets carbon fibers and technical fibers in the United States. Carbon fibers are a low-cost but high performance reinforcement for composites used as the primary building material in everyday commercial products. Zoltek Zrt. is a Hungarian subsidiary that manufactures and markets carbon fibers and technical fibers and manufactures precursor raw material used in production of carbon fibers. Zoltek de Mexico SA de CV and Zoltek de Occidente SA de CV are Mexican subsidiaries that manufacture carbon fiber and precursor raw material used in production of carbon fibers. Entec Composite Machines manufactures and markets filament winding and pultrusion equipment used in the production of large volume composite parts. The Company’s primary sales markets are in Europe and the United States, however, the Company has an increasing presence in Asia. Unless the context otherwise indicates, references to the “Company” are to Zoltek Companies, Inc. and its subsidiaries.

The Consolidated Financial Statements of the Company include the operations of its wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation. Certain prior year amounts have been reclassified to conform to the current year presentation.

USE OF ESTIMATES

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires that management make estimates and assumptions that affect amounts reported in the financial statements and accompanying notes. Actual results may differ from those estimates and assumptions.

REVENUE RECOGNITION

Sales transactions are initiated through customer purchase orders or sales agreements which are based on fixed pricing terms. The Company recognizes sales of manufactured products on the date title to the product transfers to the customer, ordinarily upon shipping. Revenues are reported net of any value-added tax or other such tax assessed by a governmental authority on our revenue-producing activities. Costs associated with shipping and handling are included in costs of sales. Revenues generated by Entec Composite Machines are recognized on a percentage of completion basis based on the percentage of total project cost incurred to date which include change orders, revisions to estimates and provisions for anticipated losses on contracts and represented 3% or less of consolidated revenues for all years presented. Revenue from sales of consigned inventory is recognized upon the use of the product by the consignee or according to terms of the contract.

ACCOUNTS RECEIVABLE

The Company reviews its accounts receivable balance on a quarterly basis to identify any specific customers for collectability issues. If the Company deems that an amount due from a customer is uncollectible, the amount is recorded as expense in the statement of operations. The Company evaluates the collectability of our accounts receivable for each of our segments based on a combination of factors. In circumstances where we are aware of a specific customer’s inability to meet its financial obligations to us (e.g., bankruptcy filing or substantial downgrading of credit), we record a specific reserve for bad debts against the amounts due reducing the net recognized receivable to the amount we estimate will be collected. For all other customers, we estimate reserves for bad debts based on the length of time receivables have been past due and our experience with collection. We incurred bad debt expense on accounts receivable of $0.5 million for 2010, $1.3 million for 2009 and $1.3 million for 2008.

CONCENTRATION OF CREDIT RISK

Zoltek’s carbon fiber products are primarily sold to customers in the composite industry and its technical fibers are primarily sold to customers in the aerospace industry. Entec Composite Machines’ products are primarily sold in the composite industry. The Company performs ongoing credit evaluations and generally requires collateral for significant export sales to new customers. The Company maintains reserves for potential credit losses and such losses have been within management’s expectations.

In fiscal 2010, 2009 and 2008, we reported net sales of carbon fiber of $49.5 million, $74.2 million and $75.1 million, respectively, to Vestas Wind Systems, a leading wind turbine manufacturer, which represented 38.6%, 53.6% and 40.4% of our net sales, respectively, during these years. The related open accounts receivable balances at September 30, 2010 and 2009 were $11.0 million and $21.1 million, respectively. Vestas was the only customer which represented greater than 10% of consolidated open accounts receivable at September 30, 2010 and 2009. The Company reported net sales of carbon fiber of $24.6 million during fiscal year 2008 to Gamesa Group, another leading wind turbine manufacturer. These sales represented 13.3% of our net sales. These were the only customers that represented greater than 10% of consolidated net sales during these years.

CASH AND CASH EQUIVALENTS

Cash equivalents include certificates of deposit and overnight repurchase agreements, all of which have initial maturities of three months or less. Cash equivalents are stated at cost plus accrued interest, which approximates market value. The Company places its temporary cash investments with high credit quality financial institutions, however, at times such investments may be in excess of the Federal Deposit Insurance Corporation (“FDIC”) insurance limit of $250,000 for U.S. banks. As of September 30, 2010, the Company had $10.3 million cash in these money market accounts.

INVENTORIES

Inventories are valued at the lower of cost or market and are removed from inventory under the first-in-first-out method (“FIFO”). Cost of inventory includes material, labor and overhead. The Company recorded inventory valuation reserves of $0.9 million and $0.7 million as of September 30, 2010 and 2009, respectively, to reduce the carrying value of inventories to a net realizable value. This evaluation includes analyses of sales levels by product and projections of future demand within specific time horizons. If future demand or market conditions are less favorable than the Company’s projections, additional inventory write-downs may be required and would be reflected in cost of sales on the Company’s statement of operations in the period in which the determination is made.

PROPERTY AND EQUIPMENT

Property and equipment are stated at cost. Cost includes expenditures necessary to make the property and equipment ready for its intended use. Expenditures to improve the asset or extend the useful life are capitalized, including interest on funds borrowed to finance the acquisition or construction of major capital additions. The Company did not record any capitalized interest in fiscal 2010 or 2009 and capitalized interest of $4.5 million during fiscal 2008. Maintenance and repairs are expensed as incurred. When property is retired or otherwise disposed of, the related cost and accumulated depreciation are removed from the accounts and any profit or loss on disposition is credited or charged to income.

The Company provides for depreciation by charging amounts sufficient to amortize the cost of properties placed in service over their estimated useful lives using straight-line methods. The range of estimated useful lives used in computing depreciation is as follows:

		Years
Buildings and improvements			30 - 40
Machinery and equipment			3 - 20
Furniture and fixtures			7 - 10
Computer hardware and software			2 - 5

Depreciation expense, including the amortization of assets recorded under capital leases, was $16.5 million, $16.4 million and $16.5 million for fiscal 2010, 2009 and 2008, respectively.

Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. If the sum of the expected future undiscounted cash flows is less than the carrying amount of the asset, a loss is recognized for the difference between the fair value and the carrying value of the asset. No impairment charges for long-lived assets were recorded during fiscal 2010, 2009 and 2008.

FOREIGN CURRENCY TRANSLATION

The Company’s Hungarian subsidiary, Zoltek Zrt., has a functional currency of the Hungarian Forint, (HUF). As a result, the Company is exposed to foreign currency risks related to this investment. The consolidated balance sheet of Zoltek Zrt. was translated from Hungarian Forints to U.S. dollars, at the exchange rate in effect at the applicable balance sheet date, while its consolidated statements of operations were translated using the average exchange rates in effect for the periods presented. The related translation adjustments are reported as other comprehensive income (loss) within shareholders’ equity. Gains and losses from foreign currency transactions of Zoltek Zrt. are included in the results of operations as other income (expense). The Hungarian Forint weakened by 9.9% against the U.S. dollar during fiscal 2010. Hungarian assets net of liabilities, excluding the long-term intercompany loan were approximately $132.8 million as of September 30, 2010.

The functional currency of Zoltek de Mexico was changed as of November 1, 2008, from the Mexican Peso to the U.S. dollar. Management made this determination based on its analysis that the currency which the majority of Mexican assets, liabilities, and operations are denominated in is U.S. dollars. The U.S. dollar-translated amounts of nonmonetary assets and liabilities at November 1, 2008 became the historical accounting basis for those assets and liabilities for all subsequent periods. As a result of this change in functional currency, exchange rate gains and losses are recognized on transactions in currencies other than the U.S. dollar and included in operations for the period in which the exchange rates changed. The Mexican Peso weakened by 19% against the U.S. dollar during the first month of fiscal 2009 before the functional currency of Zoltek de Mexico was changed to the U.S. dollar.

During fiscal 2010, currency fluctuations caused a change of $15.0 million in our accumulated other comprehensive loss.

FINANCIAL INSTRUMENTS

The Company does not hold any financial instruments for trading purposes. The carrying value of cash, accounts receivable and accounts payable approximated their fair value at September 30, 2010 and 2009.

The Company has debt obligations that bear interest at a variable rate. The carrying value of debt with a variable rate approximated its fair value at September 30 2009. There was $1.0 million of outstanding debt obligations at September 30, 2010.

In January, March and October 2004 and February 2005, the Company issued convertible notes and warrants which would require the Company to register the resale of the shares of common stock upon conversion or exercise of these securities. The Company accounted for the fair value of these outstanding warrants to purchase common stock and conversion feature of its convertible notes in accordance with ASC 815, which require the Company to separately account for the conversion feature and warrants as embedded derivatives contained in the Company’s convertible notes. Pursuant to ASC 815, the Company separated the fair value of the conversion feature from the convertible notes, since the conversion feature was determined to not be clearly and closely related to the debt host. In addition, since the effective registration of the securities underlying the conversion feature and warrants is an event outside of the control of the Company, pursuant to ASC 815, the Company recorded the fair value of the conversion feature and warrants as long-term liabilities as it was assumed that the Company would be required to net-cash settle the underlying securities.

The Company adopted the amended guidance of ASC Topic 815-40, (formerly referred to as EITF Issue No. 07-05, “Determining Whether an Instrument (or Embedded Feature) is Indexed to an Entity’s Own Stock”), on October 1, 2009. In connection with the adoption, the Company determined that its outstanding warrants as of the adoption date, which include warrants issued in May 2006, July 2006, October 2006, and December 2006, are not indexed to the Company’s own stock. Accordingly, these warrants should be treated as a derivative liability, which requires separate accounting pursuant to ASC 815. The fair value of the warrants was reclassified from equity to a derivative liability on October 1, 2009.

APPLICATION AND DEVELOPMENT EXPENSES

The Company is actively pursuing the development of a number of applications for the use of its carbon fibers and related products. The Company is executing several internal developmental strategies to further the use of carbon fiber and commercial and industrial products made from carbon fiber. As a result, the Company incurs certain costs for research, development and engineering of products and manufacturing processes. These costs are expensed as incurred and totaled approximately $8.2 million, $7.6 million and $8.1 million for fiscal years 2010, 2009 and 2008, respectively. Application and development expenses are presented as an operating item on the Company’s consolidated statement of operations. Given the Company’s position and strategy within the carbon fiber industry, it is expected that similar or greater levels of application and development expenses will be incurred in future periods.

INCOME TAXES

The Company accounts for certain income and expense items differently for financial reporting and income tax purposes. Deferred tax assets and liabilities are determined based on the difference between the financial statement and tax basis of assets and liabilities applying enacted statutory tax rates in effect for the year in which the differences are expected to reverse. A valuation allowance is provided against certain deferred tax assets when realization of those assets are not considered to be more likely than not. The Company classifies income tax-related interest and penalties as other expense, net.

EARNINGS PER SHARE

In accordance with ASC 260, the Company calculates diluted earnings per share including the impact of the Company’s potential stock equivalents. The Company has outstanding stock options, warrants and convertible debt at September 30, 2010 and 2009, which are not included in the determination of diluted earnings per share because the impact of these potential additional shares is anti-dilutive. Had these securities been dilutive, an additional 0.1 million shares for fiscal 2010, 0.3 million shares for fiscal 2009 and 0.7 million shares for fiscal 2008 would have been included in the Company’s diluted earnings per share calculation.

RECENTLY ADOPTED ACCOUNTING PRONOUNCEMENTS

In February 2010, the FASB issued Accounting Standards Update No. 2010-09, “Amendments to Certain Recognition and Disclosure Requirements” (ASU 2010-09), effective immediately. Under ASU 2010-09, SEC filers are no longer required to disclose the date through which subsequent events have been evaluated in originally issued and revised financial statements. Zoltek adopted these new requirements during the second quarter of fiscal 2010. The adoption of ASU 2010-09 did not have a material impact on the Company’s financial statements.

In January 2010, the FASB issued Accounting Standards Update No. 2010-06, “Improving Disclosures about Fair Value Measurements” (ASU 2010-06). ASU 2010-06 requires new disclosures for significant transfers in and out of Level 1 and 2 of the fair value hierarchy and the activity within Level 3 of the fair value hierarchy. The updated guidance also clarifies existing disclosures regarding the level of disaggregation of assets or liabilities and the valuation techniques and inputs used to measure fair value. The updated guidance is effective for interim and annual reporting periods beginning after December 15, 2009, with the exception of the new Level 3 activity disclosures, which are effective for interim and annual reporting periods beginning after December 15, 2010. The Company adopted the applicable disclosure requirements beginning in the second quarter of fiscal 2010. Adoption of ASU 2010-06 did not have a material impact on the Company’s financial statements.

In August 2009, the FASB issued Accounting Standards Update No. 2009-05, “Measuring Liabilities at Fair Value” (“ASU 2009-05”). This update provides amendments to ASC 820, “Fair Value Measurements and Disclosure,” for the fair value measurement of liabilities when a quoted price in an active market is not available. ASU 2009-05 is effective for reporting periods beginning after August 28, 2009. This ASU was effective for Zoltek starting in fiscal 2010, and did not have a material impact on the Company’s financial statements.

The Company adopted the amended guidance in ASC 815-40 effective October 1, 2009, which, provides revised guidance on whether a conversion option or warrant is indexed to a company’s own stock. Instruments with certain price reset features are not considered to be indexed to a company’s own stock, and consequently must be accounted for as derivatives and marked to market each reporting period. See Note 5 for more information on the adoption of ASC 815-40.

2. FINANCING TRANSACTIONS

HUNGARIAN GRANT

The Hungarian government has pledged a grant of 2.9 billion HUF to Zoltek’s Hungarian subsidiary. The grant is intended to provide a portion of the capital resources to modernize the subsidiary’s facility, establish a research and development center, and support buildup of manufacturing capacity of carbon fibers. Zoltek’s Hungarian subsidiary has received approximately HUF 0.1 billion, HUF 0.3 billion and HUF 0.7 billion in grant funding during fiscal 2010, 2009 and 2008, respectively. These funds have been recorded as a liability on the Company’s consolidated balance sheet. The liability is being amortized over the life of the assets procured by the grant funds, offsetting the depreciation expense from the assets into which the proceeds of the grant are invested. The Company has presented bank guarantees amounting to 120% of the amount of the grant as received.

The Hungarian subsidiary may be required to pay back all or a portion of the grant if, among other things, the Hungarian subsidiary: fails to obtain revenue targets; fails to employ an average annual staff of at least 1,200 employees; fails to utilize regional suppliers for at least 45% of its purchases; fails to obtain consent from the Hungarian government prior to selling assets created with grant funds; fails to use grant funds in accordance with the grant agreement; fails to provide appropriate security for the grant; makes or made an untrue statement or supplies or supplied false data in the grant agreement, grant application or during the time of the grant; defaults on its obligations by more than 30 days; withdraws any consents it gave in the grant agreement; or causes a partial or complete failure or hindrance of the project that is the subject of the grant. These targets must be achieved during a five-year measurement period from October 2012 to October 2017. Although there can be no assurance, the Company anticipates it will comply with the requirements of the grant agreement when the measurement period begins.

FINANCING ACTIVITY

Revolving Credit Facility

In February 2010, the Company extended its existing U.S. line of credit until January 1, 2011. The revolving credit facility has a total commitment of the lesser of (1) $10.0 million or (2) an eligible borrowing base equal to a percentage of eligible accounts receivable plus a percentage of eligible inventories, which as of September 30, 2010 equaled $10.0 million. There were no borrowings under the facility as of September 30, 2010.

In August 2010, the Company’s Hungarian subsidiary extended its existing line of credit until August 30, 2011. The revolving credit facility has a total commitment of the lesser of 1.9 billion HUF or a borrowing base, which as of September 30, 2010 was $9.5 million. There were no borrowings under this credit facility at September 30, 2010. The credit facility includes a term loan with quarterly interest payments.

The Company intends to extend its existing lines of credit before expiration. Based on the history of relationships with its banks and its current financial position, the Company expects it will be able to successfully extend its lines of credit.

Bond Related to Litigation

In December 2006, the Company obtained the financing to post a bond of up to $40.0 million, which represented the potential bond necessary in connection with the continuing defense of a lawsuit arising out of a dispute regarding a supply agreement.

In April 2007, the Company reported the results of various post-trial motions in ongoing litigation (see Note 8.). As of September 30, 2008, the letter of credit was collateralized by $23.5 million of restricted cash that collateralized a letter of credit posted to serve the bond. On February 9, 2009, the Company paid the judgment using $23.5 million of restricted cash, which terminated the letter of credit and related bond.

Convertible Debt

In September 2005, Zoltek entered into an agreement for new financing; a convertible debenture package of up to $50 million in a private placement with a group of institutional investors. These financings are collateralized by the carbon fiber assets of the Company’s Hungarian subsidiary.

In April 2010, the Company repaid all remaining convertible debt with cash on hand. There was no conversion of convertible debt during fiscal 2010. The following tables summarize the activity regarding our convertible debt conversions during the fiscal years ended 2009.
