PART I

Our Company

      We develop, manufacture and market high performance products used in cellular base stations to maximize the performance of wireless telecommunications networks by improving the quality of uplink signals from mobile wireless devices. Our solutions leverage our expertise in high-temperature superconducting (“HTS”) filters to “hear” wireless devices with the best possible clarity while rejecting interfering signals. We believe that this combination of interference rejection and receiver sensitivity is only possible using HTS technology. We sell our products directly to wireless carriers in the Americas, and we have plans to expand internationally. Our customers to date include ALLTEL, AT&T Wireless (now Cingular), Sprint, U.S. Cellular, and Verizon Wireless.

      Industry Background. The ability to provide high quality service to customers is becoming increasingly difficult for wireless operators as the number of subscribers rises, minutes of use increase and the market for wireless data services expands. Wireless service providers in both rural and urban areas are encountering high levels of radio frequency interference due to greater subscriber density and a larger number of users on adjacent channels. This reduced signal quality and higher percentage of dropped calls can lead to lower system utilization, decreased revenue and, ultimately, higher rates of customer churn. Service providers are also facing network capacity constraints. In particular, CDMA operators, whose spectrum employs wide communications channels for data and voice transmission, are faced with less available spectrum capacity for voice services as higher-speed data services, such as EV-DO, are introduced.

      As a result, wireless carriers are seeking to cost-effectively reduce interference, increase capacity, expand coverage to improve the quality of their systems, and, where possible, utilize their spectrum in the most efficient manner possible. Today’s restricted corporate budgets and tougher zoning laws make operators far less likely to have the option of simply deploying new base stations to achieve these performance goals.

      Our Solution. We leverage our expertise in high-temperature superconducting technology to cost effectively deliver both interference protection and increased sensitivity to our wireless carrier customers. Our solutions provide the following quality-of-service improvements:

      Our solutions consist of the following three product lines:

      We began commercial production of the SuperFilter (the precursor to the SuperLink Rx) in 1997. Our initial commercial sales of our SuperLink products were to small rural providers who had the most immediate need for range extension and coverage enhancement. We sold our first systems in the fourth quarter of 1997. We sold 83 more systems in 1998, 123 systems in 1999, 393 systems in 2000, 438 systems in 2001, 927 systems in 2002, 1,884 systems in 2003 and 697 systems in 2004. In 2002, U.S. Cellular accounted for 8% of our net commercial revenues and ALLTEL for 84% of our net commercial revenues. In 2003, ALLTEL accounted for 70% of our net commercial revenues and Verizon Wireless accounted for 15% of our net commercial revenues. For the year ended December 31, 2004, ALLTEL accounted for 63% of our net commercial revenues and Verizon Wireless accounted for 24% of our net commercial revenues.

      Our Strategy. Our objective is to provide a full range of performance improvement solutions to wireless carriers by offering our field-proven receive-chain HTS solutions, innovative duplexer designs for antenna sharing and network overlays, ground-based sensitivity improvement solutions, high-performance multiplexers and power amplifiers. The primary elements of our strategy include:

      Government Contracts. In our business model, we use government contracts as a source of funds for our commercial technology development. We typically own the intellectual property developed under these contracts, and the Federal Government receives a royalty-free, non-exclusive and nontransferable license to use the intellectual property for the United States. We acquired Conductus, Inc. on December 18, 2002. Conductus was a competing supplier of high-temperature superconducting technology for wireless networks. The acquisition of Conductus contributed $4.6 million to our government revenues in 2003. In the second quarter of 2004, we consolidated the Conductus operation into our Santa Barbara facilities.

      Corporate Information. We were incorporated in Delaware in 1987. Our facilities and executive offices are located at 460 Ward Drive, Santa Barbara, California 93111, and our telephone number is (805) 690-4500. Additional information about us is available on our website at www.suptech.com. The information on our web site is not incorporated herein by reference.

Our Wireless Products

      Commercial wireless providers can use our SuperLink Solutions to keep pace with the growing demand for wireless communications. Wireless providers may deploy our products in connection with the installation of additional base stations in a network, as well as with the installation of an entirely new network. They can also improve the performance of existing base stations and networks by retrofitting their equipment with our link enhancement products.

      Our performance improvement solutions fit into three product families: SuperLink Rx, AmpLink Rx and SuperPlex.

      During 2004, we introduced a number of variations in the AmpLink Rx and SuperPlex product lines to enable STI to offer a complete solution of products for the EV-DO roll-out in the CDMA networks of our customers.

      We introduced several new SuperLink solutions in 2003, including the SuperLink Rx 850, the most compact and lowest power cryogenic receiver front end (CRFE) in the industry, and the HTS-Ready^tm Duplexer HP, which delivers superior duplexing functionality in the 850 MHz cellular band and provides twice the amount of average power handling (1200 watts versus 600 watts) and four times as much peak power handling (40 kilowatts versus 10 kilowatts) as found in our standard HTS-Ready Duplexer 850. In August 2003, we introduced SuperLink Rx 1900, an integrated CRFE unit designed specifically for the PCS wireless market. SuperLink Rx 1900 is STI’s first fully integrated system designed for outdoor use. The fully weatherized unit includes a SuperLink Rx front-end and up to six dual duplexers in an outdoor enclosure.

      During 2002 and 2003, we were marketing a power amplifier product called the SuperLink Tx manufactured by another company. The SuperLink Tx was for wireless networks that suffer from insufficient transmit power on the downlink signal path. Our supplier for this product was acquired by a competitor of ours in November 2003. We evaluated alternative sources of power amplifiers for our customers and concluded that suitable power amplifiers are readily available from other vendors. Therefore, we have no plans to resume marketing any power amplifier products.

      Net commercial product revenues are derived from the following products:

Marketing and Sales

      We sell solutions to wireless communication service providers in the Americas and have plans to expand worldwide.

      Our earliest experience was with small rural providers who had the most immediate need for the SuperFilter® for range extension and coverage enhancement. We sold our first systems in the fourth quarter of 1997. We sold 83 more systems in 1998, 123 systems in 1999, 393 systems in 2000, 438 systems in 2001, 927 systems in 2002, 1,884 systems in 2003 and 697 systems in 2004.

      Our sales cycle has lengthened as we interact with larger Tier I cellular carriers such as Verizon and Sprint. This lengthened cycle is necessary to penetrate these accounts which, by virtue of their size, have far more needs for STI’s products than the smaller Tier II and III cellular carriers. This shift in focus was undertaken to begin a move to the suburban and urban markets where the majority of base stations are located and where the need for interference rejection is greatest.

      In mid 1999, we signed a five-year supply agreement with U.S. Cellular Corporation, one of the five largest cellular providers in the country. In March 2000, we signed a one year supply agreement with ALLTEL, an even larger domestic wireless service provider, designating STI as their supplier of HTS base station receiver solutions. In December 2001, we signed a follow-on agreement with a major customer for 1,000 SuperFilter Systems, to be delivered over five quarters. During 2003, we signed supply agreements with Verizon Wireless and another major wireless service provider.

      In December 2004, we received a follow-on purchase agreement for a minimum of $7.5 million from an existing customer. Depending on the mix of products selected by the carrier, sales under this follow on contract could exceed $11.0 million. We expect to deliver all the units under the contract in 2005.

      In 2002, U.S. Cellular accounted for 8% of our net commercial revenues and ALLTEL for 84% of our net commercial revenues. In 2003, ALLTEL accounted for 70% of our net commercial revenues and Verizon accounted for 15% of our net commercial revenues. In 2004, ALLTEL accounted for 63% of our net commercial revenues and Verizon accounted for 24% of our net commercial revenues.

      We sell using a direct sales force in the U.S. to maintain and expand our excellent customer relation with Alltel and to focus on the Tier I cellular carriers — Verizon, Cingular, Sprint, Nextel and T-Mobile. We have begun only recently directed efforts to market our products internationally and have not yet had significant international sales. We plan to supplement our direct sales by building a network of domestic distributors to focus on the Tier II and III domestic cellular carriers.

      We work with consulting firms to provide data that illustrates the benefits of deploying our products in their customers’ network, we demonstrate our products at trade shows, and participate in industry conferences. Advertising, direct mailings, and contribution of technical and application reports to recognized trade journals, are all employed, as warranted, to identify STI solutions to potential customers. We also advertise our products through our website, brochures, data sheets, application notes, trade journal reports and press releases.

      Our sales and marketing efforts are complemented by a team of sales applications engineers who manage field trials and initial customer installations and educate customers.

Backlog

      Our commercial backlog consists of accepted product purchase orders with scheduled delivery dates during the next twelve months. We had commercial backlog of $730,000 at December 31, 2004, as compared to $250,000 at December 31, 2003. We also had at December 31, 2004 minimum purchase commitments totaling $7.2 million from one customer under a general purchase agreement. We expect to fulfill these commitments during 2005, but we did not include them in our backlog because the customer has not identified the product mix and/or scheduled delivery dates.

Our Technology

      We use superconducting technology to improve both the selectivity (rejection of adjacent band interference) and the sensitivity (ability to “hear” signals better) and reduce the size of a base station receiver. Superconductors are materials that have the ability to conduct electrical energy with little or no resistance when cooled to “critical” temperatures. In contrast, electric currents that flow through normal conductors encounter resistance that requires power to overcome and generates heat. Substantial improvements in the performance characteristics of electrical systems can be made with superconductors, including reduced power loss, lower heat generation and decreased electrical noise. As these properties have been applied to radio and microwave frequency applications, new products, such as wireless filters, have been developed that are extremely small, highly sensitive and highly frequency selective.

      The discovery of superconductors was made in 1911. However, a fundamental understanding of the phenomenon of superconductivity eluded physicists until J. Robert Schrieffer (a former director and Chairman of our Technical Advisory Board), John Bardeen (co-inventor of the transistor) and Leon Cooper proposed a theory explaining superconductivity, for which they were awarded the Nobel Prize in Physics in 1972. Until 1986, all superconductor utilization was done at extremely low temperatures, below 23K (-250°C). Superconductors were not widely used in commercial applications because of the high cost and complexities associated with reaching and maintaining such low temperatures. In 1986, high temperature superconductors with critical temperatures greater than 30K (-243°C) were discovered. In early 1987, yttrium barium copper oxide (“YBCO”) was discovered, which has a critical temperature of 93K (-180°C). Shortly thereafter, thallium barium calcium copper oxide (“TBCCO”) was discovered, which has a critical temperature of 125K (-148°C). These discoveries were important because these high temperature superconductors allowed for operating temperatures higher than 77K (-196°C), or the point at which nitrogen liquefies at atmospheric pressure. These high critical temperatures allow superconductors to be cooled using less expensive and more efficient refrigeration processes. Our Company was formed following this discovery for the initial purpose of developing and commercializing high temperature superconductors.

      As part of our strategy to maintain our technological leadership, we have focused our research and development activities on high temperature superconducting (HTS) materials, RF circuitry, and cryogenics design and product application. We have internally developed our key technologies from a standard set of technology platforms. We utilize a proprietary manufacturing process for HTS thin-film production, the base material for our filtering products. An in-house design team develops the filters, which are packaged into a vacuum-sealed container for thermal insulation. The filter package is incorporated with our cryogenic cooler and then integrated with the necessary control electronics into a complete system for simple adaptation into new or existing wireless communications base stations. We believe that our filter systems provide our targeted markets with the smallest and most cost-effective products and that we are the only superconducting company that develops and manufactures all of these key components. We also utilize technologies under licenses of patents from others for our products.

      We use HTS materials as the base material to produce “thin film” microelectronics, primarily RF filters, in our SuperLink Rx product line. A number of HTS materials have been discovered with superconducting properties, but only a few have characteristics capable of commercialization. We have historically utilized TBCCO as the primary HTS material in our SuperLink product line. In the fourth quarter of 2004, we shifted all of our production from TBCCO to YBCO to lower the product manufacturing cost of the SuperLink Rx. We manufacture YBCO using proprietary processes, including proprietary manufacturing techniques. We believe that the process technology we have developed produces state of the art HTS thin-films of the highest quality with limited use of YBCO.

      We have devoted a significant portion of our engineering resources to design and model the complex RF circuitry that is basic to our products. Our RF engineering team is led by recognized international leaders in RF filter design. The expertise of this highly qualified team has allowed us to design and fabricate very precise individual components, such as RF signal filters. We have implemented computer simulation systems to design our products and this RF circuitry design has allowed us to produce extremely small, high-performance circuits. Some of our design and engineering innovations have been patented; others are the subjects of pending patent applications. We believe that our RF engineering expertise provides us with a unique competitive advantage.

      The availability of a low-cost, highly reliable, compact cooling technology is critical to the successful commercialization of our superconducting products. Prior to the Company’s efforts no such cryogenic cooler has been commercially available. In response to this lack of availability, we developed a low-cost, highly reliable low-power cooler designed to cool to 77K (-196°C) with sufficient cooling capacity for our superconducting applications. We have shipped almost 4,550 SuperLink Rx systems worldwide, logging in excess of 73 million hours of cumulative operation. The cryogenic coolers in our current models have demonstrated a Mean Time Between Failure of greater than 1 million hours. Its development was based in part on patents licensed by us from Sunpower, Inc. We believe our internally developed cooler, which is both compact enough and reliable enough to meet the most demanding wireless industry standards, provides us with a significant and unique competitive advantage.

      Cooling to cryogenic temperatures requires proper thermal isolation and packaging. Any superconducting or other cryogenically cooled device must be maintained at its optimal operating temperature, and its interaction with higher temperature components must be controlled. We have developed a variety of proprietary and patented cryogenic packaging innovations to satisfy this requirement.

How We Use Government Contracts to Fund Technology Development

      Our strategy is to continue to pursue government research and development contract awards, which complement our commercial product and technology development and allow for commercialization of the underlying technology. Since our inception in 1987, a substantial part of our net revenues have been from research and development contracts, sales directly with the U.S. government or resellers to the U.S. government. Nearly all of these revenues were paid under contracts with the U.S. Department of Defense. We have marketed to various government agencies to identify opportunities and actively solicit partners for product development proposals. Since 1988, we have successfully obtained a number of classified and non-classified government contracts for superconductor research, including one of the largest non-classified HTS awards from DARPA through the Office of Naval Research. In addition to actively soliciting government contracts, we have participated in the Small Business Innovative Research, or SBIR, program. We have been awarded 33 Phase I SBIR contracts, each of which typically generates up to $100,000

in revenues. We have been successful in converting eight of these Phase I contracts into Phase II programs, each of which typically generates up to $750,000 in revenues, and we converted one of these contracts into a Phase III program valued at $2.2 million. Since our formation, government contracts have provided us approximately $87 million of revenue, and remain a significant source of revenue today, supporting our research and development programs. We also develop and sell products to the US Government, when we can offer a unique capability. These are RF transceiver front-end products that utilize our unique HTS filter and cryogenics technologies.

Our Manufacturing Capabilities

      We currently manufacture our SuperLink Rx systems and SuperPlex products at our facilities in Santa Barbara, California. In 1998, we opened a state-of-the-art manufacturing facility in Santa Barbara. STI renovated these manufacturing areas in early 2003, the first in a series of moves that have enabled us to produce larger quantities of our SuperLink Rx products on a routine and reproducible basis. In 2003 and 2004, we expanded our controlled clean rooms, continued to develop and introduce new, state-of-the-art production and test equipment and processes, and implemented a continuous flow manufacturing strategy. In addition, performance testing and systems screening methods, along with optimized quality improvement techniques, have been instrumental in enabling our SuperLink Rx units to reach Mean Time Between Failure (MTBF) levels of more than 500,000 hours.

      We have the physical infrastructure to manufacture up to 2,800 SuperLink Rx units per year. This capacity is unchanged from the prior year. We significantly reduced the number of manufacturing personnel in 2004 in response to a decline in sales volume. We would have to significantly increase our manufacturing staff to produce units near capacity with our current infrastructure. We are holding physical capacity and staffing at their current levels to conserve cash resources. We could expand manufacturing capacity to approximately 5,000 units per year in our current facility with additional equipment.

      Our internal capabilities include a proprietary manufacturing process for thin-film materials that is scaleable for high volume production. In addition, we have established a production operation that we use to produce thin films on wafers for wireless electronics applications. Our radio frequency circuitry is designed, modeled and tested by internal engineering resources. We have in-house capabilities to pattern the superconducting material and all other aspects of radio frequency component production, including packaging the filters. We also have in-house capabilities to manufacture our cryogenic coolers at a pace consistent with current quantity requirements. The consolidation of STI’s supplier base has improved the quality of received parts, while lowering their cost and decreasing lead-times.

Intellectual Property

      We regard our product designs, design tools, fabrication equipment and manufacturing processes as proprietary and seek to protect our rights in them through a combination of patent, trademark, trade secret and copyright law and internal procedures and non-disclosure agreements. We also seek licenses from third parties for HTS materials and processes used by us, which have been patented by other parties. We believe that our success will depend, in part, on the protection of our proprietary information, patents and the licensing of key technologies from third parties.

      We have historically utilized TBCCO as the primary HTS material in our SuperLink Rx product line. In the fourth quarter of 2004, we shifted all of our production from TBCCO to YBCO to lower the product manufacturing cost of the SuperLink Rx. We have a non-exclusive license in the U.S. and selected foreign countries to the primary patents on YBCO from Lucent. We also continue to hold an exclusive worldwide license under several U.S. patents covering TBCCO from the University of Arkansas.

      We use a low-cost, highly reliable cryocooler as an essential component of our SuperLink Rx product line. We developed proprietary and patented cryogenic cooling and packaging technology for our cryocooler, but we also have a non-exclusive license from Sunpower, Inc. to various U.S. and foreign patents covering their cryocooler technology.

      As of December 31, 2004, we held 75 U.S. patents. With our recent shift from TBCCO to YBCO, we believe that the following 50 U.S. patents are currently relevant to our business:

      We also had 25 U.S. patent applications pending as December 31, 2004 which are currently relevant to our business. As of that date, we held 21 foreign issued patents and 14 foreign patents pending.

      We have trade secrets and unpatented technology and proprietary knowledge about the sale, promotion, operation, development and manufacturing of our products. We have confidentiality agreements with our employees and consultants to protect these rights.

      We own federally registered trademarks to Superconductor Technologies, Conductus and Improving the Quality of Wireless and have several other trademark registrations pending. We own other registered and unregistered trademarks, and have certain trademark rights in foreign jurisdictions.

      We license some of our patents to Bruker for NMR application, General Dynamics for government application and Star Cryogenics for Squid applications.

Competition

      The wireless communication market is intensely competitive. We face competition in various aspects of our technology and product development and in each of our target markets. Our current and potential competitors include conventional RF filter manufacturers and both established and newly emerging companies developing similar or competing HTS technologies. We also compete with companies that design, manufacture, or market conventional downlink enhancement products such as power amplifiers, as well as with companies that sell antenna-optimizing multiplexers. We also compete against companies that seek to enhance base station range and selectivity by means other than a superconducting filter. The primary competitors use tower mount and ground mount amplifiers, conventional filters, repeaters or “smart antenna” technologies. Tower mount and ground mount amplifiers pass an RF signal received by an antenna through a broad filter, followed by a low noise amplifier. These units are produced by a number of companies, which include most of the base station original equipment manufacturers (OEMs) such as Ericsson and Nokia. Filter manufacturers, including Andrew, REMEC, LGP/ Allgon, Filtronic and Radio Frequency Systems, also produce these units. Smart antennas allow base stations to focus energy more directly on individual wireless devices in order to improve capacity. Arraycom is among the leading independent companies that produces these systems. Base station manufactures, such as Ericsson, Nokia, Nortel and Lucent are also developing smart antennas for their base stations.

      In addition, we currently supply components and license technology to several companies that may eventually decide to manufacture or design their own HTS components, rather than simply purchasing or licensing our technology. With respect to our HTS materials, we compete with DuPont among others. In the government sector, we compete with universities, national laboratories and both large and small companies for research and development contracts, and with larger defense contractors, such as Raytheon and Northrop Grumman for government products. We expect increased competition both from existing competitors and a number of companies that may enter the wireless communications market.

Employees

      We employed a total of 154 persons as of December 31, 2004: 75 in manufacturing, 40 in research and development, 25 in sales and marketing and 14 in administration. Ten of our employees have Ph.D.s, and twenty-two others hold advanced degrees in physics, materials science, electrical engineering and other fields. Our employees are not represented by a labor union, and we believe that our employee relations are good.

      We are highly dependent upon the efforts of our senior management. Due to the specialized technical nature of our business, we are also highly dependent upon our ability to attract and retain qualified technical personnel, primarily in the areas of wireless communications. The loss of the services of one or more members of our senior management or technical teams could hinder our ability to achieve our product development and commercialization objectives. There is intense competition for qualified personnel in our market areas and we can give no assurance that we will be able to continue to attract and retain qualified personnel necessary for the development of our business.

Environmental Issues

      We use certain hazardous materials in its research, development and manufacturing operations. As a result, we are subject to stringent federal, state and local regulations governing the storage, use and disposal of such materials. Current or future laws and regulations could require substantial expenditures for preventative or remedial action, reduction of chemical exposure or waste treatment or disposal. Although we believe that our safety procedures for the handling and disposing of hazardous materials comply with the standards prescribed by state and federal regulations, there is always the risk of accidental contamination or injury from these materials. To date, we have not incurred substantial expenditures for preventive action with respect to hazardous materials or for remedial action with respect to any hazardous materials accident, but the use and disposal of hazardous materials involves the risk that we could incur substantial expenditures for such preventive or remedial actions. If such an accident occurred, we could be held liable for resulting damages. The liability in the event of an accident or the costs of such remedial actions could exceed our resources or otherwise have a material adverse effect on our financial condition, results of operations or cash flows.

      Unless otherwise noted, the terms “we,” “us,” and “our,” refer to the combined and ongoing business operations of Superconductor and its subsidiaries.

Risks Related to Our Business

      In each of our last five years, we have experienced significant net losses and negative cash flows from operations. If we fail to increase our revenues, specifically revenues in connection with our SuperLink products, we may not achieve and maintain profitability and may not meet our expectations or the expectations of financial analysts who report on our stock.

      Our independent registered public accounting firm has included in their report for 2004 an explanatory paragraph expressing doubt about our ability to continue as a going concern due to past losses and negative cash flows. They included a similar explanatory paragraph in their audit report for 2002 and 2003. During 2004, we incurred a net loss of $31.2 million and negative cash flows from operations of $21.6 million.

      We expect our existing cash resources, together with our line of credit and a planned inventory reduction, will be sufficient to fund our planned operations for at least the next twelve months. We have more inventory than required for current sales volumes and plan to use our excess inventory as a material source of funding in 2005. We believe the key factors to our liquidity in 2005 will be our ability to successfully execute on our plans to increase sales levels and to convert excess inventory to cash. Our cash requirements will also depend on numerous other variable factors, including the rate of growth of sales, the timing and levels of products purchased, payment terms and credit limits from manufacturers, and the timing and level of accounts receivable collections. If actual cash flows deviate significantly from forecasted amounts, we may require additional financing in the next twelve months.

      We cannot assure you that additional financing (public or private) will be available on acceptable terms or at all. If we issue additional equity securities to raise funds, the ownership percentage of our existing stockholders would be reduced, and we could deplete our reserve of authorized but unissued common stock. New investors may demand rights, preferences or privileges senior to those of existing holders of common stock. If we cannot raise needed funds, we would also be forced to make further substantial reductions in our operating expenses, which could adversely affect our ability to implement our current business plan and ultimately our viability as a company.

      We sell most of our products to a small number of wireless carriers, and we expect that this will continue. We derived 87% of our commercial product revenues from ALLTEL and Verizon Wireless in 2004 and 85% of our commercial product revenues from ALLTEL and Verizon Wireless in 2003. Our future success depends upon the wireless carriers continuing to purchase our products, and any fluctuations in demand from such customers would negatively impact our results of operations. Unanticipated demand fluctuations can have a negative impact on our revenues and business and an adverse effect on our results of operations and financial condition.

      In addition, our dependence on a small number of major customers exposes us to numerous other risks, including:

      Many of our customers also provide minimal lead-time prior to the release of their purchase orders and have non-binding commitments to purchase from us. If we fail to forecast our customer’s demands accurately, we could experience delays in manufacturing which could result in customer dissatisfaction. Additionally, these factors further impact our ability to forecast future revenue.

      The wireless communication industry is highly concentrated in nature and may become more concentrated due to anticipated industry consolidation. As a result, we believe that the number of potential customers for our products will be limited. We also face significant risks in the event any of our key customers is acquired by a company that has not adopted our technology or not adopted it to the same extent. In that event, we could face a significant decline in our sales to the acquired customer.

      Our quarterly results fluctuate due to a number of factors, including:

      We have regularly generated a large percentage of our revenues in the last month of a quarter. Since we attempt to ship products quickly after we receive orders, we may not always have a significant backlog of unfilled orders at the start of each quarter and we may be required to book a substantial portion of our orders during the quarter in which such orders ship. Our major customers generally have no obligation to purchase forecasted amounts and may cancel orders, change delivery schedules or change the mix of products ordered with minimal notice and without penalty. As a result, we may not be able to accurately predict our quarterly sales. Any shortfall in sales relative to our quarterly expectations or any delay of customer orders would adversely affect our revenues and results of operations.

      Order deferrals and cancellations by our customers, declining average sales prices, changes in the mix of products sold, delays in the introduction of new products and longer than anticipated sales cycles for our products have, in the past, adversely affected our results of operations. Despite these factors, we maintain significant finished goods, work-in-progress and raw materials inventory to meet estimated order forecasts. If our customers purchase less than the forecasted amounts or cancel or delay existing purchase orders, there will be higher levels of inventory that face a greater risk of obsolescence. If our customers desire to purchase products in excess of the forecasted amounts or in a different product mix, there may not be enough inventory or manufacturing capacity to fill their orders.

      Our expense levels and expansion plans, including plans to increase research and development efforts, manufacturing capacity and sales and marketing efforts, are based in large part on expectations of future revenue. These items of expense are relatively fixed in the short-term. We may be unable to adjust spending in a timely manner to compensate for any unexpected revenue shortfall. Consequently, operating results in any given period are likely to be disproportionately harmed if revenue in that period falls below expectations.

      Due to these and other factors, our past results are not reliable indicators of our future performance. Future revenues and operating results may not meet the expectations of stock analysts and investors. In either case, the price of our common stock could be materially adversely affected.

      Our experience with the sales cycle for telecommunications products is limited. The sales cycle includes identification of decision makers within the customers’ organizations, development of an understanding of customer-specific performance and economic issues, convincing the customer through field trial reports of the benefits of systems offered, negotiation of purchase orders and deployment.

      Because customers who purchase our systems must commit a significant amount of capital and other resources, sales are subject to delays beyond our control. Our customers must consider budgetary constraints,

comply with internal procedures for approving large expenditures and complete whatever testing is necessary for them to integrate new technologies that will affect their key operations. While the sales cycle for an initial order typically has been 12 to 24 months, we may experience longer sales cycles in the future. Such delays or lengthened sales cycles could have a material adverse effect on our business.

      Because we rely on wireless network operators for product purchases, any substantial decrease or delay in capital spending patterns in the wireless communication industry may harm our business. Demand from customers for our products depends to a significant degree upon the magnitude and timing of capital spending by these customers for constructing, rebuilding or upgrading their systems. The capital spending patterns of wireless network operators depend on a variety of factors, including access to financing, the status of federal, local and foreign government regulation and deregulation, changing standards for wireless technology, overall demand for wireless services, competitive pressures and general economic conditions. In addition, capital spending patterns in the wireless industry can be subject to some degree of seasonality, with lower levels of spending in the first and third calendar quarters, based on annual budget cycles.

      We currently purchase substrates for growth of high-temperature superconductor thin-films from a single supplier because of the quality of their substrates. A thin film is a thin layer of high-temperature superconductor material. There are additional components that we source from a single vendor due to the present volume. Our reliance on sole or limited source suppliers involves certain risks and uncertainties, most of which are beyond our control. These include the possibility of a shortage or the discontinuation of certain key components. Any reduced availability of these parts or components when required could impair our ability to manufacture and deliver our systems on a timely basis and result in the cancellation of orders, which could harm our business.

      In addition, the purchase of some of our key components involves long lead times and, in the event of unanticipated increases in demand for our SuperLink products, we may be unable to obtain these components in sufficient quantities to meet our customers’ requirements. We do not have guaranteed supply arrangements with any of these suppliers, do not maintain an extensive inventory of parts or components and customarily purchase sole or limited source parts and components pursuant to purchase orders. Business disruptions, quality issues, production shortfalls or financial difficulties of a sole or limited source supplier could materially and adversely affect us by increasing product costs, or eliminating or delaying the availability of such parts or components. In such events, our inability to develop alternative sources of supply quickly and on a cost-effective basis could impair our ability to manufacture and deliver our systems on a timely basis and could harm our business.

      Although a number of commercial superconductive electronic products have been introduced by us to date, approximately 27% of our aggregate revenue over the last five fiscal years has been derived from government research and development contracts. New products or product enhancements may or may not be successfully developed, introduced and marketed. Any new products or product enhancements that are marketed may not be well received in the marketplace or achieve any significant degree of commercial acceptance.

      The average selling price of our SuperLink products decreased in 2002 and 2003. This followed the discount on a large order of Superconductor products in December 2001. We anticipate customer pressure on our product pricing will continue for the foreseeable future. We have a plan to reduce the manufacturing cost of our SuperLink product, but there is no assurance that our future cost reduction efforts will keep pace with price erosion. We will need to further reduce our manufacturing costs through engineering improvements and economies of scale in production and purchasing in order to achieve adequate gross margins. We may not be able to achieve the required product cost savings at a rate needed to keep pace with competitive pricing pressure. Additionally, we may be forced to discount future orders. If we fail to reach our cost saving objectives or we are required to offer future discounts, our business may be harmed.

      We currently sell most of our products directly to wireless network operators in the United States. We plan, however, to expand our business in international markets by joint venturing with local entities. If and when changes in the mix of our sales channels occur, our gross profit and operating margins may fluctuate significantly.

      Our efforts to protect our proprietary rights may not succeed in preventing infringement by others or ensure that these rights will provide us with a competitive advantage. Pending patent applications may not result in issued patents and the validity of issued patents may be subject to challenge. Third parties may also be able to design around the patented aspects of the products. Additionally, certain of the issued patents and patent applications are owned jointly with third parties. Because any owner or co-owner of a patent can license its rights under jointly-owned patents or applications, inventions made by us jointly with others are not subject to our exclusive control. Any of these possible events could result in losses of competitive advantage.

      We utilize technologies under licenses of patents from others for our products. These patents may be subject to challenge, which may result in significant litigation expense (which may or may not be recoverable against future royalty obligations). Additionally, we continually try to develop new products, and, in the course of doing so, we may be required to utilize intellectual property rights owned by others and may seek licenses to do so. Such licenses may not be obtainable on commercially reasonable terms, or at all. It is also possible that we may inadvertently utilize intellectual property rights held by others, which could result in substantial claims.

      Our products incorporate a number of technologies, including high-temperature superconductor technology, technology related to other materials, and electronics technologies. Our patent positions, and that of other companies using high-temperature superconductor technology, is uncertain and there is significant risk that others, including our competitors or potential competitors, have obtained or will obtain patents relating to our products or technologies or products or technologies planned to be introduced by us.

      We believe that patents may be or have been issued, or applications may be pending, claiming various compositions of matter used in our products. We may need to secure one or more licenses of these patents. There can be no assurances that such licenses could be obtained on commercially reasonable terms, or at all. We may be required to expend significant resources to develop alternatives that would not infringe such patents or to obtain licenses to the related technology. We may not be able to successfully design around these patents or obtain licenses to them and may have to defend ourselves at substantial cost against allegations of

infringement of third party patents or other rights to intellectual property. In those circumstances, we could face significant liabilities and also be forced to cease the use of key technology.

      We were engaged in a patent dispute with ISCO International, Inc. relating to U.S. Patent No. 6,263,215 entitled “Cryoelectronically Cooled Receiver Front End for Mobile Radio Systems.” ISCO filed a complaint on July 17, 2001 in the United States District Court for the District of Delaware against us and our wholly-owned subsidiary, Conductus, Inc. The ISCO complaint alleged that our SuperFilter product and Conductus’ ClearSite product infringe ISCO’s patent. The matter went to trial on March 17, 2003.

      On April 3, 2003, the jury returned a unanimous verdict that our SuperFilter III product does not infringe the patent in question, and that ISCO’s patent is invalid and unenforceable. The jury also awarded us $3.8 million in compensatory damages based upon a finding that ISCO engaged in unfair competition and acted in bad faith by issuing press releases and contacting our customers asserting rights under this patent.

      On April 17, 2003, we filed a Motion for Attorneys’ Fees and Disbursements, in which we asked the court to award us our attorneys’ fees and other expenses. On the same date, ISCO filed a motion, asking the court to overturn the verdict and grant a new trial. In August 2003, the court rejected ISCO’s request to overturn the jury’s verdict that the patent is invalid and not infringed by the SuperFilter III product, and accepted the jury’s verdict that the patent is unenforceable because of inequitable conduct committed by one of the alleged inventors. ISCO subsequently filed a notice of appeal as to this portion of the court’s decision. The court overturned the jury’s verdict of unfair competition and bad faith on the part of ISCO and the related $3.8 million compensatory damage award to us, and we filed a notice of appeal as to this portion of the court’s decision. The trial court also denied our request for reimbursement of our legal fees associated with the case.

      On February 3, 2005, the Appellate Court reaffirmed the unanimous jury verdict that ISCO’s US patent is invalid and unenforceable. The Appellate Court also denied our request to reinstate the jury’s $3.8 million damage award to us for unfair competition and bad faith on the part of ISCO. The trial judge had overruled the jury’s finding on this point, and we appealed that portion of the judge’s ruling. We believe the decision of the Appellate Court ends this matter and do not expect any further legal action related to it.

      The field of superconductivity is characterized by rapidly advancing technology. Our success depends upon our ability to keep pace with advancing superconductive technology, including materials, processes and industry standards. Our development efforts to date have been focused principally on thallium barium calcium copper oxide and, more recently, yttrium barium copper oxide. However, these materials may not ultimately prove commercially competitive against other currently known materials or materials that may be discovered in the future.

      We will have to continue to develop and integrate advances in technology for the fabrication of electronic circuits and devices and manufacture of commercial quantities of products. We will also need to continue to develop and integrate advances in complementary technologies. We cannot assure you that our development efforts will not be rendered obsolete by research efforts and technological advances made by others or that materials other than those currently used by us will not prove more advantageous for the commercialization of superconductive electronic products.

      We utilize certain intellectual property rights under non-exclusive licenses or have granted to others the right to utilize certain intellectual property rights licensed from a third party. Because we may not have the exclusive rights to utilize such intellectual property, other parties may be able to compete with us, which may harm our business.

      Our efforts are focused on the wireless telecommunications market, including the 2G, 2.5G and 3G markets. The concentration of our resources on the wireless telecommunications market makes us potentially vulnerable to changes in this market, such as new technologies, future competition, changes in availability of capital resources or regulatory changes that could affect the competitive position and rate of growth of the wireless industry.

      Our products compete with a number of alternative approaches and technologies that increase the capacity and improve the quality of wireless networks. Some of these alternatives may be more cost effective or offer better performance than our products. Wireless network operators may opt to increase the number of transmission stations, increase tower heights, install filters and amplifiers at the top of antennas or use advanced antenna technology in lieu of purchasing our products. We may not succeed in competing with these alternatives.

      The market for superconductive electronics currently is small and in the early stages of commercialization. As superconductive electronics emerge as a viable alternative to current solutions, the market will become intensively competitive. A number of large companies with substantially greater financial resources and capabilities are engaged in programs to develop and commercialize products that may compete with those offered by us, or promote alternative solutions to meet the needs of the wireless network operators. For example, Dupont exhibited a tower top HTS front-end unit at a trade show in March 2002. Small companies, including ISCO International and CryoDevices, Inc., are also developing and commercializing superconductive electronic products for the telecommunications industry. Furthermore, academic institutions, governmental agencies and other public and private research organizations are engaged in development programs that may lead to commercial superconductive electronic products. Our success will depend on our ability to develop and maintain our technological leadership while managing the various risks described in this document.

      We derive a portion of our revenue from a few large contracts with the U.S. government. As a result, a reduction in, or discontinuance of, the government’s commitment to current or future programs could materially reduce government contract revenue.

      Contracts involving the U.S. government may include various risks, including:

      The programs in which we participate may extend for several years, but are normally funded on an annual basis. The U.S. government may not continue to fund programs under which we have entered into contracts. Even if funding is continued, we may fail to compete successfully to obtain funding pursuant to such programs.

      All costs for services under government contracts are subject to audit, and the acceptance of such costs as allowable and allocable is subject to federal regulatory guidelines. We record contract revenues in amounts which we expect to be realized upon final audit settlement. Any disallowance of costs by the government could have an adverse effect on our business, operating results and financial condition. We cannot assure you that audits and adjustments will not result in decreased revenues and net income for those years. Additionally, because of our participation in government contracts, we are subject to audit from time to time for our compliance with government regulations by various agencies. Government agencies may conduct inquiries or investigations that may cover a broad range of activity. Responding to any such audits, inquiries or investigations may involve significant expense and divert management’s attention. In addition, an adverse finding in any such audit, inquiry or investigation could involve penalties that may harm our business.

      Companies in the wireless telecommunications industry whose employees accept positions with competitors frequently claim that competitors have engaged in unfair hiring practices, trade secrets misappropriation or other related claims. We may be subject to such claims in the future as we seek to hire qualified personnel, and such claims may result in material litigation. If this should occur, we could incur substantial costs in defending against these claims, regardless of their merits.

      During 2002 and 2003, we were marketing a power amplifier product called the SuperLink Tx manufactured by another company. The SuperLink Tx was for wireless networks that suffer from insufficient transmit power on the downlink signal path. Our supplier for this product was acquired by a competitor of ours in November 2003. We have not had significant sales of the SuperLink Tx product to date, but we consider it an important part of our overall business strategy of marketing SuperLink Solutions to maximize the performance of wireless networks. We evaluated alternative sources of power amplifiers for our customers and concluded that suitable power amplifiers are readily available from other vendors. Therefore, we have no plans to resume marketing any power amplifier products. The absence of a power amplifier from our product line could adversely affect our SuperLink Solutions business strategy and adversely affect our strategy for increasing commercial revenues.

      We have established and continue to seek collaborative arrangements with corporate partners, government agencies and public and private research institutions to develop, manufacture and market superconductive electronic products. Our success depends on the development and success of these collaborative arrangements. However, we may not be able to enter into collaborative arrangements on commercially reasonable terms, and even if established, these arrangements may not succeed. If these programs are successful, our collaborative partners may seek to manufacture jointly developed products themselves or obtain them from alternative sources, rather than purchase them from us. Finally, these programs:

      We need to increase our manufacturing capabilities to meet planned production volumes, and our failure to do so would hamper our growth and long-term success. Currently, we have only limited production facilities. To date, we have focused primarily on developing fabrication processes and producing limited quantities of products. Although our processing technology derives principally from semiconductor manufacturing technology, the fabrication of high-temperature superconductor components is especially difficult because of specific properties unique to high-temperature superconductor materials.

      We cannot assure you that we can develop the necessary manufacturing capability to attain yields sufficient to meet the demand for our products at a cost that will allow us to provide a price/performance advantage to customers in comparison with other alternatives. While we have established limited production facilities for our products, we may not be able to expand our processing, production control, assembly, testing and quality assurance capabilities to produce existing or planned superconductive electronic products in adequate commercial quantities.

      Even if our products meet performance standards acceptable to the superconductive electronics market, we cannot assure you that any such products will offer price/performance advantages in comparison with other alternatives sufficient to achieve market acceptance, or that production costs will be low enough to operate profitably.

      We manufacture or “fabricate” the radio frequency filters in our SuperLink Rx, our key product, using integrated circuit manufacturing technology, and the cost of manufacturing the filters constitutes a significant part of the total product cost. We need a simpler and less costly fabrication process to manufacture large volumes of the SuperLink Rx in a cost effective manner. We have recently transitioned to a simpler and more scalable fabrication process acquired in our acquisition of Conductus, Inc. in December 2002. We could encounter significant problems with the newly designed production equipment over time. This could significantly delay the timing of our expansion plans, reduce the expected cost savings of manufacturing in high volumes and adversely affect our ability to price the SuperLink Rx competitively with competing technologies.

      Most of our competitors use simpler technologies easily outsourced to low-cost overseas manufacturing facilities. Even our new fabrication process is unique and difficult to outsource to other manufacturing facilities. Therefore, we will continue to have a competitive disadvantage in this respect which could adversely affect our ability to price the SuperLink Rx competitively with competing technologies.

      We forecast our inventory needs based on anticipated product orders to determine manufacturing requirements. If we overestimate our requirements, we may have excess inventory, and our suppliers may as well, which could increase our costs. If we underestimate our requirements, our suppliers may have inadequate inventory, which could interrupt manufacturing and result in delays in shipments and recognition of revenues. In addition, lead times for ordering materials and components vary significantly and depend on factors such as the specific supplier, contract terms and demand for each component at a given time. Accordingly, if we inaccurately forecast demand, we may be unable to obtain adequate manufacturing capacity from our suppliers to meet customers’ delivery requirements, which would harm our business.

      As a competitor in a highly technical market, we depend heavily upon the efforts of our existing senior management and technical teams. The loss of the services of one or more members of these teams could slow product development and commercialization objectives. Due to the specialized nature of high-temperature superconductors, we also depend upon our ability to attract and retain qualified technical personnel with substantial industry knowledge and expertise. Competition for qualified personnel is intense and we may not be able to continue to attract and retain qualified personnel necessary for the development of our business.

      The Federal Communications Commission strictly regulates the operation of wireless base stations in the United States. Other countries also regulate the operation of base stations within their territories. Base stations and equipment marketed for use in base stations must meet specific technical standards. Our ability to sell our high-temperature superconductor filter subsystems will depend upon the rate of deployment of other new wireless digital services, the ability of base station equipment manufacturers and of base station operators to obtain and retain the necessary approvals and licenses, and changes in regulations that may impact the product requirements. Any failure or delay of base station manufacturers or operators in obtaining necessary approvals could harm our business.

      A significant part of our long-term business strategy involves the pursuit of growth opportunities in a number of international markets, including China, Japan, Korea, Europe and Latin America. In many international markets, barriers to entry are the result of long-standing relationships between potential customers and our local suppliers and protective regulations, including local content and service requirements. In addition, pursuit of international growth opportunities may require significant investments for an extended period before any returns are realized by us from our investment.

      Our business in international markets could be adversely affected by:

      Additionally, our efforts to penetrate international markets often necessitate that we retain an agent in those markets to act on our behalf. Although the agents act autonomously, their actions reflect on us. If such an agent were to violate laws or regulations without our knowledge, such actions could cause us to incur legal liability, lose market opportunities and adversely affect our business.

      We may explore opportunities to acquire companies or technologies in the future. Entering into an acquisition entails many risks, any of which could adversely affect our business, including:

      We may acquire or make investments in complementary companies, services and technologies in the future. Other than the acquisition of Conductus in 2002, we have not made any such acquisitions or investments to date and, therefore, our ability as an organization to make acquisitions or investments is unproven.

      Acquisitions and investments involve numerous risks, including:

      In addition, future acquisitions could result in potentially dilutive issuances of equity securities, or the incurrence of debt, contingent liabilities or amortization expenses or charges related to goodwill or other intangible assets, any of which could harm our business. As a result, if we fail to properly evaluate and execute acquisitions or investments, our business and prospects may be seriously harmed.

      Our ability to successfully offer our products and implement our business plan in a rapidly evolving market requires an effective planning and management process. Anticipated growth in future operations will continue to place a significant strain on management systems and resources. We expect that we will need to continue to improve our financial and managerial controls, reporting systems and procedures, and will need to continue to expand, train and manage our work force worldwide. Furthermore, we expect that we will be required to manage multiple relationships with various customers and other third parties.

      We are subject to a number of federal, state and local governmental regulations related to the use, storage, discharge and disposal of toxic, volatile or otherwise hazardous chemicals used in our business. Any failure to comply with present or future regulations could result in fines being imposed, suspension of production or interruption of operations. In addition, these regulations could restrict our ability to expand or could require us to acquire costly equipment or incur other significant expense to comply with environmental regulations or to clean up prior discharges.

      The terrorist attacks in the United States on September 11, 2001, the declaration of war by the United States against terrorism and the war with Iraq have created significant instability and uncertainty in the world, which may have had, and may in the future have, a material adverse effect on world financial markets, including financial markets in the United States. In addition, such adverse political events may have had, and may in the future have, an adverse impact on economic conditions in the United States. Unfavorable economic conditions in the United States may have had, and may in the future have, an adverse affect on us, including, but not limited to, our ability to expand the market for our products, obtain financing as needed, enter into strategic relationships and effectively compete in the information exchange and knowledge exchange markets.

      Since we are relatively new to the commercial market and operate in a rapidly changing market, we have in the past, and may from time to time in the future, include market data from industry publications and our own internal estimates in some of the documents we file with the Securities Exchange Commission. The reliability of this data cannot be assured. Industry publications generally state that the information contained in these publications has been obtained from sources believed to be reliable, but that its accuracy and completeness is not guaranteed. Although we believe that the market data used in our SEC filings is and will be reliable, it has not been independently verified. Similarly, internal company estimates, while believed by us to be reliable, have not been verified by any independent sources.

Risks Related to Our Common Stock

      The market price of our common stock has been, and we expect will continue to be, subject to significant volatility. The value of our common stock may decline regardless of our operating performance or prospects. Factors affecting our market price include:

      Recent events have caused stock prices for many companies, including ours, to fluctuate in ways unrelated or disproportionate to their operating performance. The general economic, political and stock market conditions that may affect the market price of our common stock are beyond our control. The market price of our common stock at any particular time may not remain the market price in the future.

      Our common stock is listed on the Nasdaq National Market. We cannot assure you that it will always be listed. The Nasdaq National Market has rules for maintaining a listing, including a minimum bid price of our common stock of $1.00 per share. We may not meet all of the continued listing requirements in the future, particularly if the price of our common stock remains below $1.00 for thirty consecutive trading days. Our stock has traded recently at less than $1 per share. If our common stock is not listed with Nasdaq, it may be difficult or impossible to sell it.

      We have been named as a defendant in several substantially identical class action lawsuits filed in the United States District Court for the Central District of California in April 2004. The cases were consolidated in August 2004, and the plaintiffs filed an amended consolidated complaint in October 2004. We filed a motion to dismiss the complaint in November 2004. The plaintiffs allege securities law violations by us and certain of our officers and directors under SEC Rule 10b-5 and Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, as amended. The complaint was filed on behalf of a purported class of people who purchased our stock during the period between January 9, 2004 and March 1, 2004. The plaintiffs base their allegations primarily on the fact that we did not achieve our forecasted revenue guidance of $10 to $13 million for the first quarter of 2004. The complaint seeks unspecified damages. We believe the complaint is without merit and intend to defend this action vigorously. However, we cannot assure you that we will prevail in these actions, and, if the outcome is unfavorable to us, our reputation, profitability, balance sheet, cash flow or share price could be adversely affected.

      Furthermore, securities class action lawsuits like these have often been brought against companies following periods of stock price volatility, and we may be affected by additional litigation of this type in the future. Class action litigation can result in substantial costs and cause a diversion of management’s attention and resources. This could significantly harm our business, operating results or financial condition.

      It is possible that the acquisition of a majority of our outstanding voting stock by another company could result in Superconductor’s stockholders receiving a premium over the public trading price for our shares. Provisions of our restated certificate of incorporation and bylaws and of Delaware corporate law could delay or make more difficult an acquisition of our company by merger, tender offer or proxy contest, even if it would create an immediate benefit to our stockholders. For example, our restated certificate of incorporation does not permit stockholders to act by written consent and our bylaws generally require ninety (90) days advance notice of any matters to be brought before the stockholders at an annual or special meeting.

      In addition, our board of directors has the authority to issue up to 2,000,000 shares of preferred stock and to determine the terms, rights and preferences of this preferred stock, including voting rights of those shares, without any further vote or action by the stockholders. The rights of the holders of common stock may be subordinate to, and adversely affected by, the rights of holders of preferred sock that may be issued in the future. The issuance of preferred stock could also make it more difficult for a third party to acquire a majority of our outstanding voting stock, even at a premium over our public trading price.

      Further, our certificate of incorporation also provides for a classified board of directors with directors divided into three classes serving staggered terms. These provisions may have the effect of delaying or

preventing a change in control of Superconductor without action by our stockholders and, therefore, could adversely affect the price of our stock or the possibility of sale of shares to an acquiring person.

      We have never declared or paid cash dividends on our common stock and do not plan to pay any cash dividends in the near future. Our current policy is to retain all funds and earnings for use in the operation and expansion of our business. In addition, our debt agreements prohibit the payment of cash dividends or other distributions on any of our capital stock except dividends payable in additional shares of capital stock.

      We lease all of our properties. All of our operations, including our manufacturing facility, are located in an industrial complex in Santa Barbara, California. We occupy approximately 70,000 square feet in this complex. We have a long-term lease for 60,000 square feet that expires in 2011, and we rent the remaining 10,000 square feet on a year-to-year basis. We acquired a second leased facility in Sunnyvale, California through the acquisition of Conductus in December 2002. The facility is currently comprised of two 20,000 square feet buildings under leases, which expire in February 2006, with offices, labs and cleanrooms. One building has been subleased through January 2006 and the other building has been abandoned and is available for sublease. We believe that our Santa Barbara facilities are adequate to meet current and reasonably anticipated needs for approximately the next two years.

Patent Litigation

      We were engaged in a patent dispute with ISCO International, Inc. relating to U.S. Patent No. 6,263,215 entitled “Cryoelectronically Cooled Receiver Front End for Mobile Radio Systems.” ISCO filed a complaint on July 17, 2001 in the United States District Court for the District of Delaware against us and our wholly-owned subsidiary, Conductus, Inc. The ISCO complaint alleged that our SuperFilter product and Conductus’ ClearSite® product infringe ISCO’s patent. The matter went to trial on March 17, 2003.

      On April 3, 2003, the jury returned a unanimous verdict that our SuperFilter III product does not infringe the patent in question, and that ISCO’s patent is invalid and unenforceable. The jury also awarded us $3.8 million in compensatory damages based upon a finding that ISCO engaged in unfair competition and acted in bad faith by issuing press releases and contacting our customers asserting rights under this patent.

      On April 17, 2003, we filed a Motion for Attorneys’ Fees and Disbursements, in which we asked the court to award us our attorneys’ fees and other litigation expenses. On the same date, ISCO filed a motion, asking the court to overturn the verdict and grant a new trial. In August 2003, the court rejected ISCO’s request to overturn the jury’s verdict that the patent is invalid and not infringed by the SuperFilter III product, and accepted the jury’s verdict that the patent is unenforceable because of inequitable conduct committed by one of the alleged inventors. ISCO subsequently filed a notice of appeal as to this portion of the court’s decision. The court overturned the jury’s verdict of unfair competition and bad faith on the part of ISCO and the related $3.8 million compensatory damage award to us, and we filed a notice of appeal as to this portion of the court’s decision. The trial court also denied our request for reimbursement of our legal fees associated with the case.

      On February 3, 2005, the Appellate Court reaffirmed the unanimous jury verdict that ISCO’s US patent is invalid and unenforceable. The Appellate Court also denied our request to reinstate the jury’s $3.8 million damage award to us for unfair competition and bad faith on the part of ISCO. The trial judge had overruled the jury’s finding on this point, and we appealed that portion of the judge’s ruling. We believe the decision of the Appellate Court ends this matter and do not expect any further legal action related to it.

Class Action Lawsuits

      We were named as a defendant in several substantially identical class action lawsuits filed in the United States District Court for the Central District of California in April 2004. The cases were consolidated in

August 2004, and the plaintiffs filed an amended consolidated complaint in October 2004. The plaintiffs allege securities law violations by us and certain of our officers and directors under Rule 10b-5 and Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, as amended. The complaint was filed on behalf of a purported class of people who purchased our stock during the period between January 9, 2004 and March 1, 2004 and seeks unspecified damages. The plaintiffs base their allegations primarily on the fact that we did not achieve our forecasted revenue guidance of $10 to $13 million for the first quarter of 2004. We believe the complaint is without merit and intend to defend this action vigorously. However, we cannot assure you that we will prevail in such litigation and, if the outcome is unfavorable to us, our reputation, profitability, balance sheet, cash flow and share price could be adversely affected.

      We reached an agreement in principle with the lead plaintiffs appointed by the District Court to settle this matter. Under the terms of the proposed settlement, our insurers will pay $4.0 million into a settlement fund, and we will pay up to $50,000 of the costs of providing notice of the settlement to settlement class members. The agreement in principle remains subject to completion of mutually acceptable written settlement documents, approval by our Board of Directors, and approval by the District Court.

      No matters were submitted to security holders during the last quarter of the year.

PART II

Market for Common Stock

      Our common stock is traded on the Nasdaq National Market under the symbol “SCON.” The following table shows the high and low intraday sales prices for our common stock as reported by the Nasdaq National Market for the calendar quarters indicated:

Holders of Record

      We had 354 holders of record of our common stock on March 10, 2005. This number does not include stockholders for whom shares were held in a “nominee” or “street” name. We estimate that there are more than 34,000 round lot beneficial owners of our common stock.

Dividends

      We have never paid cash dividends and intend to employ all available funds in the development of our business. We have no plans to pay cash dividends in the near future.

Sales of Unregistered Securities

      We did not conduct any offerings of equity securities during the fourth quarter of 2004 that were not registered under the Securities Act of 1933.

Repurchases of Equity Securities

      We did not repurchase any shares of our common stock during the fourth quarter of 2004.

      The information set forth below is not necessarily indicative of results of future operations and should be read in conjunction with the Company’s Financial Statements and Notes thereto appearing in Item 15 of Part IV of this Report and “Management’s Discussion and Analysis of Financial Condition and Results of Operations”. We acquired Conductus, Inc. on December 18, 2002. The results of Conductus, Inc. are included in the consolidated financial statement starting for 13 days in 2002 following its acquisition and all periods thereafter.

General

      We develop, manufacture and market high performance products used in cellular base stations to maximize the performance of wireless telecommunications networks by improving the quality of uplink signals from mobile wireless devices. Our solutions leverage our expertise in high-temperature superconducting filters to “hear” wireless devices with the best possible clarity while rejecting interfering signals. We believe that this combination of interference rejection and receiver sensitivity is only possible using HTS technology. We sell our products directly to wireless carriers in the Americas, and we have plans to expand internationally. Our customers to date include ALLTELL, AT&T Wireless (now part of Cingular), U.S. Cellular, and Verizon Wireless.

      We derive our commercial revenues from three product lines:

      We began commercial production of the SuperFilter (the precursor to the SuperLink Rx) in 1997. Our initial commercial sales of our SuperLink products were to small rural providers who had the most immediate need for range extension and coverage enhancement. We sold our first systems in the fourth quarter of 1997. We sold 83 more systems in 1998, 123 systems in 1999, 393 systems in 2000, 438 systems in 2001, 927 systems

in 2002, 1,884 systems in 2003, and 697 systems in 2004. In 2002, U.S. Cellular accounted for 8% of our net commercial revenues and ALLTEL for 84% of our net commercial revenues. In 2003, ALLTEL accounted for 70% of our net commercial revenues and Verizon accounted for 15% of our net commercial revenues. In 2004, ALLTEL accounted for 63% of our net commercial revenues and Verizon Wireless accounted for 24% of our net commercial revenues

      In our business model, we use government contracts as a source of funds for our commercial technology development. We primarily pursue government research and development contracts which compliment our commercial product development. In other words, we undertake government contract work which has the potential to add to or improve our commercial product line. These contracts often yield valuable intellectual property relevant to our commercial business. We typically own the intellectual property developed under these contracts, and the Federal Government receives a royalty-free, non-exclusive and nontransferable license to use the intellectual property for the United States.

      During 2002 and 2003, we were marketing a power amplifier product called the SuperLink Tx manufactured by another company. The SuperLink Tx was for wireless networks that suffer from insufficient transmit power on the downlink signal path. Our supplier for this product was acquired by a competitor in November 2003. We have not had significant sales of the SuperLink Tx product to date. We evaluated alternative sources of power amplifiers for our customers and concluded that suitable power amplifiers are readily available from other vendors. Therefore, we have no plans to resume marketing any power amplifier products.

Critical Accounting Policies and Estimates

      Our discussion and analysis of our financial condition and results of operations are based upon our financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. On an on-going basis, we evaluate our estimates, including those related to bad debts, inventories, recovery of long-lived assets, income taxes, warranty obligations, contingencies and our loss contract with U.S. Cellular. We base our estimates on historical experience and on various other assumptions that we believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

      We believe the following critical accounting policies affect our more significant judgments and estimates used in the preparation of the financial statements. We maintain allowances for doubtful accounts for estimated losses resulting from the inability of our customers to make required payments. If the financial condition of our customers were to deteriorate, resulting in an impairment of their ability to make payments, additional allowances may be required. We write down our inventory for estimated obsolescence or unmarketable inventory equal to the difference between the cost of inventory and the estimated market value based upon assumptions about future demand and market conditions. If actual market conditions are less favorable than those projected by management, additional inventory write-downs may be required.

      Our inventory is valued at the lower of actual cost or the current estimated market value of the inventory. We review inventory quantities on hand and on order and record a provision for excess and obsolete inventory and/or vendor cancellation charges related to purchase commitments. Such provisions are established based on historical usage, adjusted for known changes in demands for such products, or the estimated forecast of product demand and production requirements. Our business is characterized by rapid technological change, frequent new product development and rapid product obsolescence that could result in an increase in the amount of obsolete inventory quantities on hand. As demonstrated in the past three years, demand for our products can fluctuate significantly. Our estimates of future product demand may prove to be inaccurate and we may understate or overstate the provision required for excess and obsolete inventory.

      Our net sales consist of revenue from sales of products net of trade discounts and allowances. We recognize revenue when evidence of an arrangement exists, contractual obligations have been satisfied, title

and risk of loss have been transferred to the customer and collection of the resulting receivable is reasonably assured. At the time revenue is recognized, we provide for the estimated cost of product warranties if allowed for under contractual arrangements. Our warranty obligation is effected by product failure rates and service delivery costs incurred in correcting a product failure. Should such failure rates or costs differ from these estimates, accrued warranty costs would be adjusted.

      In connection with the sales of its commercial products, the Company indemnifies, without limit or term, its customers against all claims, suits, demands, damages, liabilities, expenses, judgments, settlements and penalties arising from actual or alleged infringement or misappropriation of any intellectual property relating to its products or other claims arising from its products. The Company cannot reasonably develop an estimate of the maximum potential amount of payments that might be made under its guarantee because of the uncertainty as to whether a claim might arise and how much it might total.

      Contract revenues are principally generated under research and development contracts. Contract revenues are recognized utilizing the percentage-of-completion method measured by the relationship of costs incurred to total estimated contract costs. If the current contract estimate were to indicate a loss, utilizing the funded amount of the contract, a provision would be made for the total anticipated loss. Revenues from research related activities are derived primarily from contracts with agencies of the United States Government. Credit risk related to accounts receivable arising from such contracts is considered minimal. These contracts include cost-plus, fixed price and cost sharing arrangements and are generally short-term in nature.

      All payments to us for work performed on contracts with agencies of the U.S. Government are subject to adjustment upon audit by the Defense Contract Audit Agency. Based on historical experience and review of current projects in process, we believe that the audits will not have a significant effect on our financial position, results of operations or cash flows. The Defense Contract Audit Agency has audited us through 2002.

      In connection with the acquisition of Conductus we recognized $20 million of goodwill. Goodwill is tested for impairment annually in the fourth quarter after the annual planning process, or earlier if events occur which require an impairment analysis be performed. We operate in a single business segment as a single reporting unit. The first step of the impairment test, used to identify potential impairment, compares the fair value based on market capitalization of the entire Company with the book value of its net assets, including goodwill. (The Company’s market capitalization is based the closing price of our common stock as traded on NASDAQ multiplied by our outstanding common shares.) If the fair value of the Company exceeds the book value of our net assets, our goodwill is not considered impaired. If the book value of our net assets exceeds our fair value, the second step of the goodwill impairment test shall be performed to measure the amount of impairment loss. The second step of the goodwill impairment test, used to measure the amount of impairment loss, compares the implied fair value of the goodwill with the book value of that goodwill. If the carrying amount of the reporting unit goodwill exceeds the implied fair value of that goodwill, an impairment loss shall be recognized in an amount equal to that excess. At December 31, 2004, we tested the goodwill for possible impairment and determined that there was no impairment. The fair value of the Company based on its market capitalization totaled $149.7 million which is in excess of the total book value of the Company. Therefore, our goodwill was not considered impaired. This goodwill will again be tested for impairment in the fourth quarter of 2005 or earlier if events occur which require an earlier assessment. If the carrying amount exceeds its implied fair value, an impairment loss will be recognized equal to the excess. Any future impairment of our goodwill could have a material adverse effect on our financial position and results of operations.

      We periodically evaluate the realizability of long-lived assets as events or circumstances indicate a possible inability to recover the carrying amount. Long-lived assets that will no longer be used in business are written off in the period identified since they will no longer generate any positive cash flows for the Company. Periodically, long-lived assets that will continue to be used by the Company need to be evaluated for recoverability. Such evaluation is based on various analyses, including cash flow and profitability projections. The analyses necessarily involve significant management judgment. In the event the projected undiscounted cash flows are less than net book value of the assets, the carrying value of the assets will be written down to their estimated fair value. We completed such an analysis as of the fourth quarter of 2004 and determined that

no write down was necessary. Our estimates of future cash flows may prove to be inaccurate and we may understate or overstate the write down of long lived assets.

      As permitted under Statement of Financial Accounting Standards No. 123 (SFAS 123), “Accounting for Stock-Based Compensation”, we have elected to follow Accounting Principles Board Opinion No. 25, “Accounting for Stock Issued to Employees” in accounting for its stock options and other stock-based employee awards. Pro forma information regarding net loss and loss per share, as calculated under the provisions of SFAS 123, are disclosed in the notes to the financial statements. We account for equity securities issued to non-employees in accordance with the provision of SFAS 123 and Emerging Issues Task Force 96-18.

      If we had elected to recognize compensation expense for employee awards based upon the fair value at the grant date consistent with the methodology prescribed by SFAS 123, our net loss and net loss per share would have been increased to the pro forma amounts indicated below:

      Our valuation allowance against the deferred tax assets is based on our assessments of historical losses and projected operating results in future periods. If and when we generate future taxable income in the U.S. against which these tax assets may be applied, some portion or all of the valuation allowance would be reversed and an increase in net income would consequently be reported in future years.

      We are currently involved as a defendant in a securities class action lawsuit. This matter is discussed below in “Legal Proceedings.” We reached an agreement in principle with the lead plaintiffs appointed by the District Court to settle this matter. Under the terms of the proposed settlement, our insurers will pay $4.0 million into a settlement fund, and we will pay up to $50,000 of the costs of providing notice of the settlement to settlement class members. The agreement in principle remains subject to completion of mutually acceptable written settlement documents, approval by our Board of Directors, and approval by the District Court. We recorded an estimated liability of $4.0 million for the settlement and an estimated receivable of $4.0 million for the expected insurance proceeds. We periodically reassess our potential liability as additional information becomes available. If we later determine that the probable loss is greater than our reserve or expected insurance proceeds, we would record an additional reserve for the potential additional loss. The ultimate amount of further losses, if any, could materially impact our results of operations, financial condition or cash flows.

Backlog

      Our commercial backlog consists of accepted product purchase orders with scheduled delivery dates during the next twelve months. We had commercial backlog of $730,000 at December 31, 2004, as compared to $250,000 at December 31, 2003. We also had at December 31, 2004 minimum purchase commitments

totaling $7.2 million from one customer under a general purchase agreement. We expect to fulfill these commitments during 2005, but we did not include them in our backlog because the customer has not identified the product mix and/or scheduled delivery dates.

Results of Operations

      We acquired Conductus, Inc. on December 18, 2002. Conductus was located in Sunnyvale California and was a competing supplier of high-temperature superconducting technology for wireless networks. We discontinued their competing commercial product line (the ClearSite) and incorporated their technology into our commercial product line (the SuperLink). The results of Conductus are included in the consolidated financial statement for 13 days in 2002 following its acquisition and for all periods thereafter. The acquisition did not have a significant impact on the results of operations for the year ended December 31, 2002. Conductus contributed $4.6 million to our government revenues in 2003. We consolidated the Conductus operation into our Santa Barbara facilities in the second quarter of 2004.

      Net revenues decreased by $26.4 million, or 53%, from $49.4 million in 2003 to $23.0 million in 2004. Net revenues consist primarily of commercial product revenues and government contract revenues. We also generate some additional revenues from sublicensing our technology.

      Net commercial product revenues decreased to $16.8 million in 2004 from $38.6 million in 2003, a decrease of $21.8 million, or 56%. The decrease is primarily the result of a $21.9 million decline in sales of our SuperLink Rx products. We experienced significant declines in sales of these products to our two largest customers. We anticipated some decline in sales to one of these customers and expected to offset it with the addition of another new major customer in 2004. Our sales efforts were adversely affected in 2004 by, among other things, changes in capital spending patterns and consolidation in the telecommunications industry. The average selling price of our SuperLink Rx product is comparable between the periods. Our two largest customers accounted for 87% of our net commercial revenues in 2004 and 85% in 2003. These customers generally purchase products through non-binding commitments with minimal lead-times. Consequently, our commercial product revenues can fluctuate dramatically from quarter to quarter based on changes in our customers’ capital spending patterns.

      Net commercial product revenue consists of gross commercial product sales proceeds less sales discounts and the allocation of certain sales proceeds to a warrant issued to one customer in 1999 under a long-term supply agreement. The following table summarizes the calculation of net commercial product revenue for 2004 and 2003:

      Government contract revenues decreased by $4.6 million, or 43%, from $10.8 million in 2003 to $6.2 million in 2004. This decrease is primarily attributable to the completion of contracts in 2003 and 2004 that have not been replaced.

      Cost of commercial product revenues includes all direct costs, manufacturing overhead, provision for excess and obsolete inventories and restructuring and impairment charges relating to the manufacturing operations. The cost of commercial product revenue totaled $23.4 million for 2004 and $28.2 million for 2003.

Decreased costs result primarily from decreased unit shipments partially offset by increased provision for excess and obsolete inventories and restructuring and impairment charges.

      Our cost of sales includes both variable and fixed cost components. The variable component consists primarily of materials, assembly and test labor, overhead, which includes equipment and facility depreciation, transportation costs and warranty costs. The fixed component includes test equipment and facility depreciation, purchasing and procurement expenses and quality assurance costs. Given the fixed nature of such costs, the absorption of our production overhead costs into inventory decreases and the amount of production overhead variances expensed to cost of sales increases as production volumes decline since we have fewer units to absorb our overhead costs against. Conversely, the absorption of our production overhead costs into inventory increases and the amount of production overhead variances expensed to cost of sales decreases as production volumes increase since we have more units to absorb our overhead costs against. As a result, our gross profit margins generally decrease as revenue and production volumes decline due to lower sales volume and higher amounts of production overhead variances expensed to cost of sales; and our gross profit margins generally increase as our revenue and production volumes increase due to higher sales volume and lower amounts of production overhead variances expensed to cost of sales.

      The following is an analysis of our gross profit and margins:

      We had a negative gross profit of $6.6 million in 2004 from the sale of our commercial products as compared to positive gross profit of $10.3 million in 2003. We experienced negative gross profits in 2004 primarily because the reduced level of commercial sales was insufficient to cover our fixed manufacturing overhead costs. Our gross margins were also adversely impacted by a $4.8 million charge for excess and obsolete inventory and a $1.1 million charge for restructuring activities and fixed asset write downs. This compares to $719,000 for charge for excess and obsolete inventory in 2003. We regularly review inventory quantities on hand and provided an allowance for excess and obsolete inventory based on numerous factors including sales backlog, historical inventory usage, forecasted product demand and production requirements for the next twelve months.

      Contract research and development expenses totaled $4.5 million in 2004 as compared to $6.9 million in 2003. These decreases were the result of lower expenses associated with performing a fewer number of government contracts offset by higher expenses associated with completing a contract.

      Other research and development expenses relate to development of new and wireless commercial products. We also incur design expenses associated with reducing the cost and improving the manufacturability of our existing products. These expenses totaled $5.0 million in 2004 as compared to $4.7 million in the prior year. The increase is due to increased commercial products development efforts.

      Selling, general and administrative expenses totaled $16.1 million in 2004, as compared to $20.6 million in 2003. The decrease in 2004 results primarily from lower ISCO litigation expenses, the closure of our Sunnyvale facility, reduced payments under our management incentive program and restructuring activities. These decreases were partially offset by higher legal expenses associated with the class action lawsuit and higher expenses related to the documentation and testing of our internal controls as required by the Sarbanes Oxley Act of 2002.

      During 2004, we implemented several restructuring programs to streamline our operations and reduce our cost structure. We recorded cash and non-cash restructuring charges of $3.6 million for these activities. We consolidated our Sunnyvale operations into our Santa Barbara facility and reduced our total workforce. The workforce reduction included reductions associated with the Sunnyvale consolidation, as well as other strategic

reductions in the organization. In addition, as part of the consolidation, we accelerated a program to implement of a new, lower cost wafer deposition process called Reactive Co-Evaporation.

      As a result of all cost reduction initiatives, we saved approximately $2.4 million in the quarter ended December 31, 2004, as compared to the first quarter of 2004.

      In connection with our 2005 annual planning process performed in the fourth quarter of 2004, we concluded that we would no longer use our thallium high temperature superconducting related technology beyond 2005 because alternative technologies were determined to be more cost effective and we decided we no longer wanted to support two HTS material technologies. As a result, we recorded non-cash charges of $715,000 primarily relating to the write-off of thallium related manufacturing equipment, patents and licenses since they will not be recovered from future cash flows. Also, during our annual planning process we concluded that we would no longer continue to develop or maintain and would abandon certain other non core business patents and patents no longer considered blocking our business, and certain purchased technology. As a result of the abandonment of the purchased technology and patents, we recorded non-cash charges of $842,000 relating to the write-off of these patents and purchased technology since they will not be recovered from future cash flows.

      The following table summarizes our actual restructuring and impairment charges for 2004 and our estimated charges for 2005 relating to the actions taken in 2004:

      Interest income decreased in 2004 as compared to the prior year because we had less cash available for investment.

      Interest expense in 2004 totaled $1.2 million as compared to $504,000 in 2003. This increase is related primarily to an $802,000 non-cash charge for warrants issued to the lenders in connection with a bridge loan in April 2004 (discussed below).

      We were named as a defendant in several substantially identical class action lawsuits filed in the United States District Court for the Central District of California in April 2004. We recently reached an agreement in principle with the lead plaintiffs appointed by the District Court to settle this matter. Under the terms of the proposed settlement, our insurers will pay $4.0 million into a settlement fund, and we will pay up to $50,000 of the costs of providing notice of the settlement to settlement class members. The agreement in principle remains subject to completion of mutually acceptable written settlement documents, approval by our Board of Directors, and approval by the District Court. We recorded a liability at December 31, 2004 on our consolidated balance sheet for the proposed amount of the settlement of $4,050,000. In addition, because the insurance carrier involved in this suit agreed to pay $4.0 million of the settlement amount, and therefore, recovery from the insurance carrier is probable, we also recorded a receivable on our balance sheet for that amount. Accordingly, the settlement had a $50,000 impact on our statement of operations for the year ended December 31, 2004. We included this amount in our selling, general and administrative expenses.

      We had a net loss of $31.2 million for the year ended December 31, 2004 as compared to $11.3 million in the same period last year.

      The net loss available to common shareholders totaled $0.37 per common share in the 2004, as compared to $0.18 per common share in the same period last year.

      Total net revenues increased by $27.0 million, or more than 100%, from $22.4 million in 2002 to $49.4 million for 2003. This increase is primarily due to higher commercial product sales and government and other contract revenues, including the government contract and other revenue from our acquisition of Conductus in December 2002.

      Net commercial product revenues increased to $38.6 million in 2003 from $17.6 million in 2002, an increase of $21.0 million, or more than 100%. This increase is primarily the result of an increase in sales of our SuperLink Rx products of $17.2 million, increased sales of our multiplexer product of $1.2 million and a $2.3 million decrease in sales proceeds allocated to warrants issued to U.S. Cellular. The average selling price for the SuperLink Rx decreased 7% on our SIX-Pak units and increased 1% on our TWO-Pak units. Our two largest customers accounted for 85% of our net commercial revenues in 2003 and 92% in 2002.

      Net commercial product revenue consists of gross commercial product sales proceeds less sales discounts and the allocation of certain sales proceeds to a warrant issued to one customer in 1999 under a long-term supply agreement. The following table summarizes the calculation of net commercial product revenue for 2003 and 2002:

      Government contract revenues increased by $6.0 million, or more than 100%, from $4.8 million in 2002 to $10.8 million in 2003. This increase results primarily from the acquisition of Conductus which totaled $4.6 million and the remainder to a modest increase in other government contracts at our Santa Barbara facility.

      Cost of commercial product revenue includes all direct costs, manufacturing overhead and related start-up costs. The cost of commercial product revenues totaled $28.2 million for 2003. For 2002, cost of commercial products revenues totaled $19.3 million, and was reduced by amortization credits of $2.0 million for the accrual of a non-cash contract loss on the purchase order from U.S. Cellular. Please read the discussion under the caption “Non-Cash Charges for Warrants Issued to U.S. Cellular.” For 2002, excluding these amortization credits, the cost of commercial revenues totaled $21.3 million compared to $28.2 million in 2003. Increased costs resulting from increased unit shipments and higher costs associated with ramping up our manufacturing capacity were offset by lower material and labor costs per unit and the effect of increased manufacturing efficiencies.

      The following is an analysis of our gross profit and margins for 2002 and 2003:

      We generated positive commercial gross margins of $10.3 million in 2003 from the sale of our commercial products, as compared to negative gross margins of $1.7 million for 2002. The improvement is due to increased commercial product revenues and decreased manufacturing cost per unit.

      Contract research and development expenses totaled $6.9 million in 2003 and $2.5 million in 2002. The increase is primarily from the acquisition of Conductus. The remainder is attributable to a modest increase in government contract revenues at our Santa Barbara facility.

      Other research and development expenses are for internally funded development of our commercial products. These expenses increased to $4.7 million in 2003, and are comparable to $4.5 million in 2002.

      Selling, general and administrative expenses totaled $20.6 million in 2003 as compared to $15.0 million in 2002. This increase results primarily from increased domestic and international marketing and sales efforts, higher expenses related to the acquired Conductus operations and higher ISCO litigation expenses. ISCO litigation expenses totaled $4.8 million in 2003, as compared to $3.1 million in 2002.

      Interest income decreased in 2003 as compared to 2002 due to decreased levels of cash available for investment and the decline in interest rates.

      Interest expense increased in 2003 as compared to 2002 and resulted from the increased debt incurred in the fourth quarter of 2002, from short-term borrowings in 2003 and accretion of long term liabilities recorded in the Conductus acquisition.

      We had a net loss of $11.3 million for 2003 as compared to $19.5 million in 2002.

      The net loss available to common shareholders totaled $11.3 million in 2003, or $0.18 per common share, as compared to $21.3 million, or $0.89 per common share, in 2002. The amounts for 2002 include a charge of $1.8 million for a non-cash deemed distribution on preferred stock.

Liquidity and Capital Resources

      As of December 31, 2004, we had working capital of $16.1 million, including $12.8 million in cash and cash equivalents, as compared to working capital of $15.6 million at December 31, 2003, which included $11.1 million in cash and cash equivalents. We currently invest our excess cash in short-term, investment-grade, money-market instruments with maturities of three months or less. We believe that all of our cash investments would be readily available to us should the need arise.

      Cash and cash equivalents increased by $1.7 million from $11.1 million at December 31, 2003 to $12.8 million at December 31, 2004. Cash was used in operations for the purchase of property and equipment and for the payment of short and long-term borrowings. These expenditures were offset by cash received from the sale of common stock in two public offerings. Cash and cash equivalents decreased by $7.1 million from $18.2 million at December 31, 2002 to $11.1 million at December 31, 2003. Cash used in operations was partially offset by cash received from the sale of common stock and warrants in a private placement, exercises of warrants and options and a net increase in borrowings.

      Cash used in operations totaled $21.6 million in 2004. We used $18.3 million to fund the cash portion of our net loss. We also used cash to fund a $10.7 million increase in inventory, prepaid expenses and other

current assets, patents and licenses and accounts payable payments. Inventory increased during 2004 due to lower than expected sales. These uses were partially offset by cash generated from the collection of accounts receivable of $7.4 million. Cash used in operations totaled $18.5 million in 2003. We used $7.2 million to fund the cash portion of our net loss. We also used cash to fund an $11.2 million increase in accounts receivable, inventory, patents and licenses, other assets and accounts payable. Depreciation and amortization expense increased in the year ended December 31, 2003 due to increased amortization related to the acquired technology in the Conductus acquisition and increased fixed assets expenditures in the prior year. Cash used in operations totaled $20.0 million in 2002. We used $16.0 million to fund the cash portion of our net loss. We also used cash to fund a $3.9 million increase in inventory, accounts receivable, patents and licenses and reduction in accounts payable.

      Net cash used in investing activities totaled $5.5 million in 2002, $4.4 million in 2003 and $1.8 million in 2004. These expenditures all related primarily to purchases of manufacturing equipment and facilities improvements to increase our production capacity. In 2003, cash of $500,000 was used to pay upfront license fees for a new technology license. In 2002, cash of $429,000 was used in the acquisition of Conductus, Inc. and $374,000 was provided by the release of restrictions on $374,000 of cash obtained through the Conductus acquisition.

      Net cash provided by financing activities totaled $25.1 million in 2004. Cash received from the sale of common stock and exercise of options and warrants totaled $28.1 million and borrowings against our credit and bridge loan facilities totaled $5.6 million. These sources of cash were partially offset by payments against our credit and bridge loan facilities totaling $7.9 million and payments against our long-term debt totaling $645,000. Net cash provided by financing activities totaled $15.8 million in 2003. Cash received from the sale of common stock and warrants totaled $13.9 million and net borrowings against our credit facility totaled $3.3 million and was partially offset by the reduction in long-term borrowings of $1.4 million. Net cash provided by financing activities totaled $28.4 million in 2002. Cash received from the sale of common stock and warrants totaled $31.9 million, which was partially offset by a $3.0 million premium paid on conversion of the Series E Convertible Preferred Stock and payments against our long-term debt totaling $519,000.

      We have historically financed our operations through a combination of cash on hand, cash provided from operations, equipment lease financings, available borrowings under bank lines of credit and both private and public equity offerings. We have effective registration statements on file with the SEC covering the public resale by investors of all the common stock issued in our private placements, as well as any common stock acquired upon exercise of their warrants.

      We have an existing line of credit from a bank. It is a material source of funds for our business. The line of credit expires March 17, 2005, and we expect to renew it for another year on substantially the same terms as currently in effect. The loan agreement is structured as a sale of our accounts receivable and provides for the sale of up to $5.0 million of eligible accounts receivable, with advances to us totaling 80% of the receivables sold. Advances bear interest at the prime rate (5.25% at December 31, 2004) plus 2.50% subject to a minimum monthly charge. Outstanding amounts under this borrowing facility at December 31, 2004 totaled $938,000. The amount outstanding is repaid upon collection of the underlying accounts receivable. Advances are collateralized by a lien on all of our assets. Under the terms of the agreement, we continue to service the sold receivables and are subject to recourse provisions.

      We completed three financing transactions during 2004. First, in April 2004, we temporarily expanded our credit facility and secured a bridge loan to provide interim funding until we could complete a larger public offering. We temporarily amended our existing line of credit to increase borrowing capacity from 80% to 95% of eligible accounts receivable. We concurrently secured a commitment for a $2.0 million secured bridge loan from an investor. The investor subsequently funded $1.5 million of the bridge loan. We issued to the lenders warrants to purchase in the aggregate 600,000 shares of common stock at $1.85 per share. The bridge loan was subsequently paid in full on May 26, 2004. Upon repayment of the bridge loan, our credit facility reverted back to its original terms.

      Second, we completed a public offering of 23,000,000 shares of common stock at $0.80 per share during the second quarter of 2004 raising net proceeds of $16.7 million.

      Third, we completed a public offering of 15,600,000 shares of common stock at $0.70 per share during the fourth quarter of 2004 raising net proceeds of $10.1 million.

      We incur various contractual obligations and commercial commitments in our normal course of business. They consist of the following:

      Our capital lease obligations are for property and equipment and total $89,000.

      Our operating lease obligations consist of facility leases in Santa Barbara and Sunnyvale, California. We assumed the Sunnyvale leases in connection with our acquisition of Conductus, Inc. in 2002. The Sunnyvale lease obligations total $1,386,000 and are due in monthly installments through February 2006. We consolidated the Sunnyvale operations into our Santa Barbara facility in 2004 and recorded a liability for the present value of the remaining obligations under the Sunnyvale leases. We included these liabilities in the financial statements under Accrued Liabilities and Other Long Term Liabilities.

      We have entered into various licensing agreements requiring royalty payments ranging from 0.13% to 2.5% of specified product sales. Some of these agreements contain provisions for the payment of guaranteed or minimum royalty amounts. Typically, the licensor can terminate our license if we fail to pay minimum annual royalties.

      In the normal course of business, we incur purchase obligations with vendors and suppliers for the purchase of inventory, as well as other goods and services. These obligations are generally evidenced by purchase orders that contain the terms and conditions associated with the purchase arrangements. We are committed to accept delivery of such material pursuant to the purchase orders subject to various contract provisions which allow us to delay receipt of such orders or cancel orders beyond certain agreed upon lead times. Cancellations may result in cancellation costs payable by us.

      At December 31, 2004, we had the following contractual obligations and commercial commitments:

      We plan to invest approximately $500,000 in fixed assets during 2005.

      Our principal sources of liquidity consist of existing cash balances and funds expected to be generated from future operations. We expect our existing cash resources, together with our line of credit and a planned inventory reduction, will be sufficient to fund our planned operations for at least the next twelve months. We have more inventory than required for current sales volumes and plan to use our excess inventory as a material source of funding in 2005. We believe the key factors to our liquidity in 2005 will be our ability to successfully execute on our plans to increase sales levels and to convert excess inventory to cash. Our cash requirements will also depend on numerous other variable factors, including the rate of growth of sales, the timing and levels of products purchased, payment terms and credit limits from manufacturers, and the timing and level of accounts receivable collections.

      If actual cash flows deviate significantly from forecasted amounts, we may require additional financing in the next twelve months. We cannot assure you that additional financing (public or private) will be available on acceptable terms or at all. If we issue additional equity securities to raise funds, the ownership percentage of our existing stockholders would be reduced. New investors may demand rights, preferences or privileges senior to those of existing holders of common stock. If we cannot raise any needed funds, we might be forced to make further substantial reductions in our operating expenses, which could adversely affect our ability to implement our current business plan and ultimately our viability as a company.

      In the last several years, we have raised money from investors to cover our operating losses through public and private offerings. Our ability to continue to raise funds using these methods may be adversely impacted by any future NASDAQ listing issues. Our continued NASDAQ listing requires us to maintain a minimum of $1 share price. Our stock has recently begun trading at levels significantly below $1 per share. Although NASDAQ de-listing would not be immediate, our lower share price could make capital raising more difficult.

      Our financial statements have been prepared assuming that the Company will continue as a going concern. The factors described above raise substantial doubt about our ability to continue as a going concern. Our financial statements do not include any adjustments that might result from this uncertainty.

      Our independent registered public accounting firm has included in their audit report for fiscal 2004 an explanatory paragraph expressing doubt about our ability to continue as a going concern. They included a similar explanatory paragraph in their audit report for 2002 and 2003. In 2004, we incurred a net loss of $31.2 million and had negative cash flows from operations of $21.6 million. In response, we reduced direct and indirect labor and continued to cut fixed costs. We also consolidated our Sunnyvale operations into our Santa Barbara facility and accelerated the implementation of a new, lower cost wafer deposition process.

Non-Cash Charges for Warrants Issued To U.S. Cellular

      In August 1999, we entered into a warrant agreement with United States Cellular Corporation (“U.S. Cellular”) where the exercise of a warrant to purchase up to 1,000,000 shares of common stock was conditioned upon future product purchases by U.S. Cellular. Under the terms of the warrant, U.S. Cellular vests in the right to purchase one share of common stock at $4 per share for every $25 of SuperFilter systems purchased. The warrant is immediately exercisable with respect to any vested shares and expires August  27, 2004. For accounting purposes, we are allocating proceeds from sales under this agreement between commercial product revenues and the estimated value of the warrants vesting in connection with those sales. The estimated fair value of the warrants in excess of the related sales, when applicable, is recorded in cost of commercial product revenues.

      In September 2000, we received a $7.8 million noncancelable purchase order from U.S. Cellular for SuperFilter® systems to be shipped over the next nine quarters. In consideration for the purchase order, we amended the August 1999 warrant agreement and vested 312,000 warrants to U.S. Cellular. The vested

warrants are immediately exercisable, not subject to forfeiture, and U.S. Cellular has no other purchase obligations.

      We estimated the fair value of the warrants vesting upon receipt of this order at $5,635,000 using the Black-Scholes option-pricing model and recorded this amount as a deferred warrant charge in the statement of stockholders’ equity. As SuperFilter systems are shipped under this purchase order, the related sales proceeds will be allocated between stockholders’ equity and commercial product revenue using the percentage relationship which existed between the fair value of the warrants as recorded in September 2000 and the amount of the non-cancelable purchase order. During 2001 and 2002 sales proceeds of $2,237,000 and $2,280,000, respectively, for shipments pursuant to this purchase order were allocated to the deferred warrant charge and proceeds of $879,000 and $967,000, respectively, were recorded as commercial product revenues under this purchase order.

      After the allocation of sales proceeds under the $7.8 million purchase order to the related warrants, the estimated cost of providing products under the purchase order exceeded related revenue by $5.3 million. The resulting loss was reflected in the results of operations for the year ended December 31, 2000. During the years ending December 31, 2001 and 2002, $2,243,000 and $1,998,000, respectively, of this reserve was reversed against the cost of product delivered under this purchase order.

      During the fourth quarter of 2002, deliveries under the $7.8 million purchase order were completed. For accounting purposes, proceeds from subsequent sales to U.S. Cellular under this agreement are again being allocated between commercial product revenue and the estimated value of the warrants vesting using the Black-Scholes option-pricing model. For subsequent product sales, in the fourth quarter of 2002, the year ended December 31, 2003 and December 31, 2004, U.S. Cellular vested in the right to exercise the warrant and purchase a total of 22,540, 38,088 and 7,024 shares of common stock, respectively. Sales proceeds allocated to warrants vesting in 2002, 2003 and 2004 totaled $3,000, $90,000 and less than $1,000, respectively.

      This warrant expired unexercised on August 27, 2004.

Net Operating Loss Carryforward

      As of December 31, 2004, we had net operating loss carryforwards for federal and state income tax purposes of approximately $244.6 million and $119.4 million, respectively, which expire in the years 2005 through 2024. Of these amounts $93.7 million and $30.2 million, respectively resulted from the acquisition of Conductus. Included in the net operating loss carryforwards are deductions related to stock options of approximately $24.1 million and $13.1 million for federal and California income tax purposes, respectively. To the extent net operating loss carryforwards are recognized for accounting purposes the resulting benefits related to the stock options will be credited to stockholders’ equity. In addition, we have research and development and other tax credits for federal and state income tax purposes of approximately $2.6 million and $2.4 million, respectively, which expire in the years 2005 through 2024. Of these amounts $972,000 and $736,000, respectively resulted from the acquisition of Conductus.

      Due to the uncertainty surrounding their realization, we have recorded a full valuation allowance against our net deferred tax assets. Accordingly, no deferred tax asset has been recorded in the accompanying balance sheet.

      Section 382 of the Internal Revenue Code imposes an annual limitation on the utilization of net operating loss carryforwards based on a statutory rate of return (usually the “applicable federal funds rate”, as defined in the Internal Revenue Code) and the value of the corporation at the time of a “change of ownership” as defined by Section 382. We completed an analysis of our equity transactions and determined that we had a change in ownership in August 1999 and December 2002. Therefore, the ability to utilize net operating loss carryforwards incurred prior to the change of ownership totaling $101.6 million will be subject in future periods to an annual limitation of $1.3 million. In addition, we acquired the right to Conductus’ net operating losses, which are also subject to the limitations imposed by Section 382. Conductus underwent three ownership changes, which occurred in February 1999, February 2001 and December 2002. Therefore, the ability to utilize Conductus’ net operating loss carryforwards of $93.7 million incurred prior to the ownership

changes will be subject in future periods to annual limitation of $700,000. Net operating losses incurred by us subsequent to the ownership changes totaled $51.4 million and are not subject to this limitation.

Future Accounting Requirements

      In December 2004, the Financial Accounting Standards Board issued SFAS No. 123® (revised 2004), “Share-Based Payment” which amends SFAS Statement 123 and will be effective for public companies for interim periods or annual periods beginning after June 15, 2005. The new standard will require us to recognize compensation costs in our financial statements in an amount equal to the fair value of share-based payments granted to employees and directors. We are currently evaluating how we will adopt the standard and evaluating the effect that the adoption of SFAS 123® will have on our financial position and results of operations.

      In November 2004, the FASB issued SFAS No. 151, “Inventory Costs”, and amendment of ARB No. 43, Chapter 4. This statement amends the guidance in ARB No. 43, Chapter 4, Inventory Pricing, to clarify the accounting for abnormal amounts of idle facility expense, freight, handling costs, and wasted material (spoilage). Paragraph 5 of ARB No. 43, Chapter 4, previously stated that “...under some circumstances, items such as idle facility expense, excessive spoilage, double freight, and rehandling costs may be so abnormal as to require treatment as current period charges....” SFAS No. 151 requires that those items be recognized as current-period charges regardless of whether they meet the criterion of “so abnormal.” In addition, this statement requires that allocation of fixed production overheads to the cost of conversion be based on the normal capacity of the production facilities. The provisions of SFAS 151 shall be applied prospectively and are effective for inventory costs incurred during fiscal years beginning after June 15, 2005, with earlier application permitted for inventory costs incurred during fiscal years beginning after the date this Statement was issued. We do not expect the adoption of SFAS No. 151 to have a material impact on our financial position and results of operations.

Market Risk

      We are exposed to various market risks, including changes in interest rates. Market risk is the potential loss arising from adverse changes in market rates and prices. We do not enter into derivatives or other financial instruments for trading or speculation purposes.

      At December 31, 2004, we had approximately $11.9 million invested in a money market account yielding approximately 2.013%. Assuming a 1% decrease in the yield on this money market account and no liquidation of principal for the year, our total interest income would decrease by approximately $119,000 per annum. Also, at December 31, 2004 we had $938,000 outstanding under a bank borrowing arrangement bearing interest at the prime rate (5.25% at December 31, 2004) plus 2.50%. Assuming a 1% increase in the prime rate interest and that the amount was outstanding for the entire year, interest expense would increase approximately $9,000.

Management’s Report on Internal Control over Financial Reporting

      Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rule 13a-15(f). Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework in Internal Control — Integrated Framework, issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO Framework”). Based on our evaluation under the COSO Framework, our management concluded that our internal control over financial reporting was effective as of December 31, 2004.

      Our management’s assessment of the effectiveness of our internal control over financial reporting as of December 31, 2004 has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report on Page F-1 of this Annual Report on Form 10-K.

Changes in Internal Control over Financial Reporting

      There have been no changes in our internal control over financial reporting during the quarter ended December 31, 2004 that have materially affected or are reasonably likely to materially affect our internal control over financial reporting.

      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 risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of

Superconductor Technologies Inc.:

      We have completed an integrated audit of Superconductor Technologies Inc.’s 2004 consolidated financial statements and of its internal control over financial reporting as of December 31, 2004 and audits of its 2003 and 2002 consolidated financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Our opinions, based on our audits, are presented below.

Consolidated financial statements and financial statement schedule

      In our opinion, the consolidated financial statements listed in the accompanying index appearing under Item 15(a)(1) present fairly, in all material respects, the financial position of Superconductor Technologies Inc. and its subsidiaries at December 31, 2004 and 2003, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2004 in conformity with accounting principles generally accepted in the United States of America. In addition, in our opinion, the financial statement schedule listed in the index appearing under Item 15(a)(2) presents fairly, in all material respects, the information set forth therein when read in conjunction with the related consolidated financial statements. These financial statements and financial statement schedule are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements and financial statement schedule based on our audits. We conducted our audits of these statements 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 the financial statements are free of material misstatement. An audit of financial statements includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

      The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 2 to the consolidated financial statements, the Company has had recurring losses and used $21.6 million in cash for operations in 2004. These matters raise a substantial doubt about the Company’s ability to continue as a going concern. Management’s plans in regard to these matters are also described in Note 2. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Internal control over financial reporting

      Also, in our opinion, management’s assessment, included in “Management’s Report on Internal Control Over Financial Reporting,” appearing under Item 9A, that the Company maintained effective internal control over financial reporting as of December 31, 2004 based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO), is fairly stated, in all material respects, based on those criteria. Furthermore, in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2004, based on criteria established in Internal Control — Integrated Framework issued by the COSO. The Company’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. Our responsibility is to express opinions on management’s assessment and on the effectiveness of the Company’s internal control over financial reporting based on our audit. We conducted our audit of internal control over financial reporting 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. An audit of internal control over financial reporting includes obtaining an understanding of internal control over financial reporting, evaluating management’s assessment, testing and evaluating the design and operating effectiveness of internal control, and performing such other procedures as we consider necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinions.

      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 (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) 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 (iii) 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.
