Item 1.    Business.

Overview

        We design, develop, produce and support a technologically-advanced portfolio of small unmanned aircraft systems, or UAS, that we supply primarily to organizations within the U.S. Department of Defense, or DoD, and fast charge systems for electric industrial vehicle batteries that we supply to commercial customers. We derive the majority of our revenue from these two business areas and we believe that both the small UAS and fast charge markets are in the early stages of development and have significant growth potential. Additionally, we believe that some of the innovative potential products in our research and development pipeline will emerge as new growth platforms in the future, creating market opportunities.

        The success we have achieved with our current products stems from our investment in research and development and our ability to invent and deliver advanced solutions, utilizing our proprietary technologies, to help our government and commercial customers operate more effectively and efficiently. Our core technological capabilities, developed through more than 35 years of innovation,

2

include lightweight aerostructures and electric propulsion systems, efficient electric energy systems and storage, high-density energy packaging, miniaturization, controls integration and systems engineering optimization.

        Through our fiscal year ended April 30, 2008, we were organized into three segments based on our business operations, UAS, PosiCharge Systems, and Energy Technology Center, which focused primarily on the development of innovative, efficient electric energy technologies for internal and external customers, and also developed, produced and supported a line of electronic test equipment used for research and development activities. As of May 1, 2008, the operations of our PosiCharge Systems and Energy Technology Center were consolidated to form the newly named Efficient Energy Systems segment.

Our Strategy

        We intend to grow our business by maintaining leadership in the markets for small UAS and fast charge systems and by creating new products that enable us to enter and lead new markets. Key components of this strategy include the following:

        Expand our current solutions to existing and new customers.    Our small UAS and PosiCharge fast charge systems and services are leaders in their respective North American markets. We intend to increase the penetration of our small UAS products within the U.S. military, the military forces of allied nations and non-military U.S. customers. We believe that the increased use of our small UAS in the U.S. military will be a catalyst for increased demand by allied countries, and that our efforts to pursue new applications will help to create non-military opportunities. We similarly intend to increase the penetration of PosiCharge fast charge systems into existing and new customers in North America and globally.

        Deliver innovative solutions.    Innovation is the primary driver of our growth. We plan to continue research and development efforts to develop better, more capable products and services, both in response to and in anticipation of customer needs. We believe that by continuing to invest in research and development, we will continue to deliver innovative, new products that address market needs within and outside of our current target markets, enabling us to create new opportunities for growth.

        Foster our entrepreneurial culture and continue to attract, develop and retain highly-skilled personnel.    We have created a corporate culture that encourages innovation and an entrepreneurial spirit, which helps to attract highly-skilled professionals. We intend to nurture this culture to encourage the development of the innovative, highly technical solutions that give us our competitive advantage. A core component of our culture is the demonstration of trust and integrity in all of our interactions, contributing to a positive work environment and engendering trust among our customers.

        Preserve our agility and flexibility.    We are able to respond rapidly to evolving markets and deliver new products and system capabilities quickly, efficiently and affordably. We believe that this ability helps us to strengthen our relationships with customers. We intend to maintain our agility and flexibility, which we believe to be important sources of differentiation when we compete against larger companies and competitors with more extensive resources.

Our Customers

        We sell the majority of our small UAS to organizations within the DoD, and the majority of our PosiCharge fast charge systems to commercial customers. The Energy Technology Center generates revenue from both government and commercial customers.

        During our fiscal year ended April 30, 2008, approximately 62% of our sales were made to the U.S. Army pursuant to orders made under contract by the U.S. Army on behalf of itself as well as

3


several other services of the U.S. Military. Other U.S. government agencies and government subcontractors accounted for 22% of our sales revenue, while purchases by foreign and commercial customers accounted for the remaining 16% of sales revenue during our fiscal year ended April 30, 2008.

Industry Background

    Small UAS

        The market for our small UAS has grown significantly over the last several years due to the U.S. military's post-Cold War transformation and the demands of the global war on terrorism. Following the end of the Cold War, the U.S. military began its transformation into a smaller, more agile force that fights through a network of observation, communication and precision targeting technologies. This transformation accelerated following the terrorist attacks of September 11, 2001, as the U.S. military required improved observation and targeting of combat enemies who operate in small groups, often embedded in dense population centers or dispersed in remote locations. We believe that UAS, which range from large systems, such as Northrop Grumman's Global Hawk and General Atomics' Predator, to small systems, such as our Raven and Wasp, are an integral part of this transforming military force because they provide critical observation and communications capabilities while reducing risk to individual "warfighters." Our small UAS can provide real-time observation and communication capabilities to these small units who directly control them. As we explore opportunities to develop new markets for our small UAS such as border surveillance and petrochemical industry infrastructure monitoring, we expect further growth through the introduction of UAS technology to non-military applications once rules are established for their safe and effective operation in the national airspace.

    Fast Charge Systems

        Fast charge technology, which charges a battery with a high electrical current while the battery remains in the vehicle, eliminates the need for frequent battery changing and a dedicated battery room. This approach increases productivity, reduces operating costs and improves facility safety. The earliest adopters of fast charge technology include the automotive and air transportation industries. Large food and retail industry customers have more recently begun to utilize fast charge technology.

        Our PosiCharge fast charge systems, accessories, and installation and post-sale services, are designed to improve productivity and safety for operators of electric industrial vehicles, such as forklifts and airport ground support equipment, by improving battery and fleet management. Electric industrial vehicles, over 100,000 of which were shipped in North America during 2007, are powered by large onboard batteries that can consume up to 17 cubic feet and weigh up to 3,500 pounds. In multi-shift fleet operations, traditional charging systems require users to exchange vehicle batteries throughout the day because these batteries discharge their energy through vehicle usage and there is insufficient vehicle downtime to recharge them during a shift. As a result, drivers must leave the work area when the battery reaches a low state of charge and drive to a dedicated battery changing room, which often occupies valuable floor space and is frequently located far from a driver's work area. The driver or dedicated battery attendant must then remove the battery from the vehicle, place it on a storage rack, connect it to a conventional battery charger, identify a fully-charged battery, move it into the vehicle's battery compartment and reconnect the battery to the motor before the driver may return to the work area. These battery changes take place every day in thousands of facilities around the world, resulting in reduced material movement and increased operating costs. Furthermore, depending on the type of battery, conventional battery chargers can require up to eight hours to recharge the battery, which then must cool for up to an additional eight hours before it is ready to be used again. Consequently, depending on vehicle usage and the number of shifts in an operation, a fleet may require more than one battery per vehicle, which necessitates additional storage space, chargers and maintenance time. Moreover, the high levels of heat generated by conventional battery chargers during their normal use

4


can cause excessive evaporation of the water contained in the battery and damage to the battery's components. Over time, this evaporation of fluid and damage to components result in battery degradation and negatively affect the battery's life.

Our Solutions

    UAS Products

        Our small UAS, including Raven, Wasp, Dragon Eye and Puma, are designed to provide valuable Intelligence, Surveillance and Reconnaissance, or ISR, including real-time tactical reconnaissance, tracking, combat assessment and geographic data, directly to the small tactical unit or individual warfighter, thereby increasing flexibility in mission planning and execution. Our small unmanned aircraft wirelessly transmit critical live video and other information generated by their payload of electro-optical or infrared sensors, enabling the operator to view and capture images, during the day or at night, on a hand-held ground control unit. All of our ground control units allow the operator to control the aircraft by programming it for GPS-based autonomous navigation using operator-designated way-points and, with the exception of Dragon Eye's ground control unit, also provide for manual flight operation. These ground control units are designed for durability and ease of use in harsh environments and incorporate a user-friendly, intuitive, graphical user interface. With the exception of Dragon Eye, all of our small unmanned aircraft operate from a common ground control unit.

        All of our small UAS are designed to be man-portable, assembled without tools in less than five minutes and launched and operated by one person with limited training required. The efficient and reliable electric motors used in all of our small UAS are powered by replaceable modular battery packs that can be changed in seconds, enabling rapid return to flight. All of our small UAS can be recovered through an autonomous landing feature that enables a controlled descent to a designated location.

        In military applications, our systems enable tactical leaders to observe the next corner, intersection or ridgeline in real-time. This information facilitates faster, safer movement through urban and mountainous environments and can enable troops to act on intelligence rather than react to an attack. Moreover, by providing this information, our small UAS reduce the risk to warfighters and to the surrounding population by providing the ability to tailor the military response to the threat. U.S. military personnel regularly use our small UAS, such as Raven, for force protection, combat enemy observation and damage assessment missions. These reusable systems are easy to transport, assemble and operate and are relatively quiet when flying at typical operational altitudes of 200 to 300 feet due to our efficient electric propulsion systems. Furthermore, their small size makes them difficult to see from the ground. In addition, the low cost of our small UAS relative to larger systems and alternatives makes it practical for warfighters to deploy these assets directly.

        Our small UAS also include spare equipment, alternative payload modules, batteries, chargers, repairs and Internet-enabled customer support. We provide training by our highly-skilled instructors, who typically have extensive military experience, and continuous refurbishment and repair services for our products. We currently maintain a forward operating depot in Iraq to support the large fleet of our small UAS deployed there. By maintaining close contact with our customers and users in the field, we gather critical feedback on our products and incorporate that information into ongoing product development and research and development efforts. This approach enables us to improve our solutions in response to, and in anticipation of, evolving customer needs.

        The U.S. Army projects its total demand for our Raven small UAS at approximately 1,900 new systems, of which we had delivered approximately 43% as of April 30, 2008. For the fiscal years ended April 30, 2008, 2007 and 2006, sales of our UAS products and services accounted for 86%, 84% and 80%, respectively, of our revenue.

    UAS Services

        In support of our small UAS we offer a suite of services that help to ensure the successful operation of our products by our customers. We provide spare parts as well as repair, refurbishment and replacement services through our services operation. We designed our services operation to minimize supply chain delays and provide our customers with spare parts, replacement aircraft and support whenever and wherever they need them. We developed an Internet-accessible logistics system that provides our customers with the status of their returned products and their inventory that we help manage. This secure system also provides recent parts and repairs history and tracks usage data to enable inventory optimization forecasting. Our Simi Valley, California facility, which also serves as the primary depot for repairs and spare parts, is currently supplemented by a forward supply depot in Iraq.

        We provide complete training services to support all of our small UAS. Our highly-skilled instructors typically have extensive military experience. We deploy training teams throughout the continental United States and abroad to support our customers' wide variety of training needs on both production and development stage systems. We offer turnkey flight operation services to customers requiring the information generated by our small UAS.

        The services portion of our business has grown rapidly, corresponding to the increase in total flight hours that our small UAS are utilized.

    PosiCharge Fast Charge Systems

        Developed from our work on electric and hybrid electric vehicles and advanced battery systems in the 1990s, PosiCharge fast charge systems quickly and safely recharge industrial vehicle batteries while they remain in the vehicle during regularly scheduled breaks and other times when the vehicle is not in use, thereby maintaining a sufficient level of energy throughout the workday. By eliminating battery changing, PosiCharge fast charge systems improve supply chain productivity by returning time to the vehicle operator to complete more work. Furthermore, because of their advanced efficient energy capabilities, PosiCharge fast charge systems can reduce the amount of electricity required to support electric industrial vehicles by several hundred dollars per year per vehicle as compared to conventional battery chargers. Many customers who implement our fast charge systems in their facilities are able to

6

re-purpose the battery changing room floor space for more productive activities and create a safer working environment, as drivers or battery attendants no longer need to exchange large, lead-acid batteries.

        Developed over years of advanced battery testing and usage, the proprietary battery charging algorithms built into PosiCharge fast charge systems, which are tailored to battery type, brand and size, maximize the rate at which energy is sent into the battery while minimizing heat generation and its damaging effects. We believe our work to develop these algorithms contributed to the major battery manufacturers offering battery warranties for fast charge, which provided a critical assurance to customers that fast charge systems would not harm their batteries. In combination with a weekly equalization charge that balances all the cells within the battery pack, our "intelligent" charging process enhances the performance of batteries and helps them to achieve improved operation. We believe that competitive fast charge and conventional charge systems, which lack our current and voltage regulating tailored charge algorithms and monitoring capabilities, may actually contribute to lower battery performance and lifespan over time, ultimately resulting in higher battery costs and degraded vehicle performance.

        Our complete line of fast charge products enables us to design customized system solutions for each facility based on its shift schedule, workload, truck type and battery type. By customizing the system to unique customer requirements, we can help to reduce the cost of implementing and operating fast charge systems while maximizing the benefit of PosiCharge fast charge systems to our customers. Our complete solution consists of system configuration, installation, training, asset management and performance monitoring. Moreover, while fast charge technology itself provides significant operational and financial benefits to our customers, we believe that our ability to integrate the system effectively into customer operations through installation services, asset management capabilities and post-sale support increases the value proposition. We believe that this "turnkey" approach to the fast charge market represents a potential source of competitive advantage.

        We project that PosiCharge fast charge system customers typically begin to realize cost savings when compared to battery changing within the first twelve months of operation. Operators of large fleets of electric industrial vehicles who use PosiCharge fast charge systems in multiple settings, including factories, distribution centers, cold storage facilities and airport tarmacs, include Ford Motor Company, SYSCO Corporation, Southwest Airlines and IKEA. For the fiscal years ended April 30, 2008, 2007 and 2006, sales of PosiCharge Systems products accounted for 9%, 10% and 14%, respectively, of our revenue. We believe that the market for PosiCharge fast charge systems is young and that continued diversification of our customer base will support increased penetration of this technology into target markets.

    PosiCharge Products

        Our PosiCharge fast charge systems and support products consist of the following:

        PosiCharge ELT.    ELT, our original fast charge product, is designed to safely deliver the highest current (up to 600 amps) to electric forklifts, such as counterbalance or "sit-down" trucks, used in heavy-duty applications.

        PosiCharge DVS.    Capable of charging either one vehicle at a time at up to 500 amps or two vehicles simultaneously at up to 320 amps each, DVS is designed to deliver lower up-front installation and ongoing utility costs when compared to other single vehicle fast chargers. Because DVS is a high-current, stand-alone system, it is capable of supporting a variety of specific charging needs, including isolated vehicles in remote areas, smaller fleets requiring smaller systems and heavy-duty applications with variable usage patterns.

7

        PosiCharge MVS.    MVS, a multiple-port, multi-vehicle fast charge system, is designed for charging low-to-medium-duty electric industrial vehicles, such as pallet jacks, reach trucks and tow motors, in distribution, warehousing, and general manufacturing settings. Each system is capable of charging up to 16 vehicles at the same time and is designed to deliver greater cost-savings as the number of vehicles simultaneously charged increases.

        PosiCharge SVS.    A cost-effective, flexible fast charge solution for single vehicle applications, the SVS line of fast change systems has a compact footprint and provides up to 500 amps of current through its single port.

        PosiCharge GSE.    Ruggedized for outdoor use in extreme weather conditions, GSE is designed to deliver all the benefits of our MVS product to the airport ground support equipment market.

        Accessories.    In addition to fast charge systems, we offer a variety of accessories to help our customers integrate PosiCharge into their operations. Single point, automatic watering systems ensure that battery electrolyte is maintained at an optimal level and that watering occurs at the optimal time, thereby contributing to battery health and reducing labor costs associated with manual watering. Charge indicator lights provide fleet supervisors with color codes visible from a distance that indicate the status of the battery's charge. Battery-mounted fans for use with the heaviest-duty types of vehicles keep these batteries cool to improve battery performance. Cable management options and charger stands provide customers the flexibility to install PosiCharge in the best location.

    Energy Technology Center

        Our Energy Technology Center, which was consolidated with our PosiCharge Systems segment effective May 1, 2008, produces and sells a line of advanced electric load and sink systems used to test batteries, electric motors and fuel cell systems, and provides contract engineering services to internal and external customers. In addition to generating revenue, these contract services enhance our technical skills and capabilities, enabling us to conduct internal research and development to support existing products and to create new products to satisfy new market needs.

        Contract Engineering Services.    We actively pursue internal and externally funded projects that help us to strengthen our technological capabilities. We submit bids to large research customers such as the Defense Advanced Research Projects Agency, the U.S. Air Force and the U.S. Special Operations Command for projects that we believe have future commercial application. Contract engineering services conducted through our Energy Technology Center represent a strategic source of innovation for us. Providing these services contributes to the development and enhancement of our technical competencies. In an effort to manage the ability of our key technical personnel to support multiple, high-value research and development initiatives, we attempt to limit the volume of contract engineering projects that we accept. This process enables us to focus these personnel on projects we believe offer the greatest current and future value to our business. Consequently, while these projects typically add to our operating margin, we are not seeking to grow this service offering at this time.

        Power Processing Systems.    Our Power Processing Systems represent a product line of advanced electric load and sink systems that are used mainly by research and development organizations in the public and private sectors to test batteries, electric motors and fuel cell systems. Power Processing Systems customers include many of the world's largest automotive manufacturers, including General Motors, as well as departments of the U.S. government.

        For the fiscal years ended April 30, 2008, 2007 and 2006, sales by our Energy Technology Group accounted for 5%, 6% and 6%, respectively, of our revenue.

8

Backlog

        We define funded backlog as unfilled firm orders for products and services for which funding currently is appropriated to us under the contract by the customer. As of April 30, 2008 and 2007, our funded backlog was approximately $82.0 million and $60.9 million, respectively. We expect that 90% percent of our funded backlog will be filled during our fiscal year ended April 30, 2009.

        In addition to our funded backlog, we also had unfunded backlog of $384.3 million and $478 million as of April 30, 2008 and April 30, 2007, respectively. We define unfunded backlog as the total remaining potential order amounts under cost reimbursable and fixed price contracts with multiple one-year options, or indefinite delivery indefinite quantity, or IDIQ contracts. Unfunded backlog does not obligate the U.S. government to purchase goods or services. There can be no assurance that unfunded backlog will result in any orders in any particular period, if at all. Unfunded backlog does not include the value of options to purchase additional aircraft included in our Global Observer contract. Management believes that unfunded backlog does not provide a reliable measure of future estimated revenues under our contracts.

        Because of possible future changes in delivery schedules and/or cancellations of orders, backlog at any particular date is not necessarily representative of actual sales to be expected for any succeeding period, and actual sales for the year may not meet or exceed the backlog represented. Our backlog is typically subject to large variations from quarter to quarter as existing contracts expire, or are renewed, or new contracts are awarded. As described under "Government Contracting Process," a majority of our contracts, specifically our IDIQ contracts, do not currently obligate the U.S. government to purchase any goods or services. Additionally, all U.S. government contracts included in backlog, whether or not funded, may be terminated at the convenience of the U.S. government.

Technology, Research and Development

    Technological Competence and Intellectual Property

        Our company was founded by the late Dr. Paul B. MacCready, the former Chairman of our board of directors and an internationally renowned innovator who was instrumental in creating our culture. This culture has enabled us to attract and retain highly-motivated, talented employees and has established our reputation as an innovator.

        The innovations of our company and our founder include, among others: the world's first effective human-powered and manned solar-powered airplanes; the first modern consumer electric car (the EV1 prototype for General Motors); the world's highest flying airplane in level flight, Helios, a solar-powered UAS that reached over 96,000 feet in 2001; and, more recently, the world's first liquid hydrogen-powered UAS. The Smithsonian Institution has selected four vehicles developed by us for its permanent collection. Our history of innovation excellence is the result of our creative and skilled employees whom we encourage to innovate and develop new technologies.

9

        Our primary areas of technological competence, UAS and efficient electric energy, represent the sum of numerous technical skills and capabilities that help to differentiate our approach and product offerings. The following table highlights a number of our key technological capabilities:

UAS Technology   Efficient Electric Energy Technology
• Lightweight, low speed aerostructures and propeller design   • Battery management and chemistries
• Miniaturized avionics and micro/nano unmanned aircraft systems   • Power electronics and controls
• Image stabilization and target tracking   • Lightweight electric propulsion
• Unmanned autonomous control systems   • Thermal management
• Payload integration   • High-density energy packaging
• Hydrogen propulsion systems and high-pressure-ratio turbochargers   • Electric power generation, storage and management
• Stratospheric flight operations   • Charging algorithms
• Fluid dynamics   • On/off grid controls
• System integration and optimization   • Controls integration and systems engineering
    • System integration and optimization

        We follow a formal process to evaluate new ideas and inventions that ultimately includes review by our commercialization committee to determine if a technology, product or solution is commercially feasible. The committee members are selected by our Chief Executive Officer. Currently our commercialization committee consists of our Chief Executive Officer and Chief Financial Officer. In addition, each of our operating segments has its own internal evaluators who determine whether potential commercialization opportunities and intellectual property developments merit review by our commercialization committee. A fundamental part of this process of innovation is a screening process that helps business managers identify commercial opportunities that support current or desired technological capabilities. Similarly, we manage new product and business concepts through a rigorous commercialization process that governs spending, resources, time and intellectual property considerations. An important element of our commercialization process is ensuring that our technology and business development activities are strongly linked to customer needs in attractive growth markets. Throughout the process we revalidate our customer requirement assumptions to ensure that the products and services we ultimately deliver are of high value.

        As a result of our commitment to research and development, we possess an extensive portfolio of intellectual property in the form of patents, trade secrets, copyrights and trademarks across a broad range of unmanned aircraft system and advanced energy technologies. As of April 30, 2008, we had 91currently effective issued patents and approximately 45 patents pending. In many cases, we opt to protect our intellectual property through trade secrets as opposed to filing for patent protection in order to preserve the confidentiality of such intellectual property.

        The U.S. Government has licenses to our patented technology that was specifically developed in performance of government contracts, and it may use or authorize others to use the inventions covered by such patents for government purposes.

        While our intellectual property rights in the aggregate are important to the operation of our business segments, we do not believe that any existing patent, license or other intellectual property right is of such importance that its loss or termination would have a material adverse effect on our business taken as a whole.

10

    Research, Development and Commercialization Projects

        One important aspect of our technology research and development activity is the development and commercialization of innovative solutions that we believe can become new products and open opportunities for us to enter large new markets or accelerate the growth of our current products. We invest in an active pipeline of these commercialization projects that range in maturity from technology validation to early market adoption. We cannot predict when, if ever, these projects will be successfully commercialized, or the level of capital expenditures they could require, which could be substantial. Four new products that we have been developing are described below.

        Global Observer is a high-altitude, long-endurance UAS under development to address the critical need for affordable, 24-hour, 365-days-a-year persistent communications and ISR. The continuation of years of research with both our own and U.S. government sponsored development funding, the configuration now being developed under a three-year, $57 million joint capabilities technology demonstration program, or JCTD, with several agencies of the U.S. government is being designed to operate at up to 65,000 feet for up to a week between landings. We expect the efficiency and endurance (three to four times the longest flight time of existing fixed-wing aerial options) of this UAS to provide for dramatically lower operating and total life cycle costs for missions where persistent communications or surveillance is critical. The Global Observer platform is intended to be the equivalent of a twelve-mile-high, low-cost, redeployable satellite, providing a footprint of coverage of up to 600 miles in diameter and capable of providing a broad array of services, including high-speed broadband data, video and voice relay and ISR. We expect these capabilities to provide the foundation for multiple high-value applications including communications relay and ISR missions for defense and homeland security, storm tracking, telecommunications infrastructure, wildfire detection/tracking and disaster recovery services.

        Switchblade.    We are developing a packaged UAS offering that is designed to deliver different payloads in different sizes and configurations based on mission requirements. One example of this offering is a single-use, hand-held, small UAS with the ability to eliminate a target with minimal collateral damage through the detonation of an onboard explosive upon impact. This system would be launched by a single individual and operated through our standard ground control unit. This version of Switchblade is being designed to allow the operator to identify a threat using the ground control unit, lock-on to the target via visual information on the screen, and neutralize it by triggering an autonomous terminal guidance phase which results in the aircraft's impact with the target and simultaneous detonation of the explosive payload. We believe that recent combat experience indicates that such a capability would be of great value and could significantly improve the ability to neutralize hostile elements, such as snipers, machine gunners and mortar launchers. Development of this system under customer funding has achieved desired milestones including demonstrating dynamic target tracking and real-time aircraft course correction.

        Digital Data Link.    We are developing a robust, packet-switched, digital network module designed for extremely small size, weight, power and latency requirements that would enable it to operate on our small UAS. Advantages of the switch to digital technology include reduced bandwidth usage for transmissions relative to analog transmissions, resulting in the ability to simultaneously operate more small UAS in closer proximity than was previously possible. Flight testing has successfully demonstrated this capability using our small UAS to route data, voice and video.

        Architectural Wind.    Recognizing the limited options available for renewable energy generation in urban environments, our engineers and scientists utilize our high-efficiency electric powertrain and propeller design capabilities to create a new type of wind energy system that can be installed on buildings. The result is Architectural Wind, a small, modular wind turbine designed to take advantage of wind over buildings to provide renewable electricity in a more cost-effective manner. Initial market exploration has revealed significant interest in this product, which has a visually compelling design.

11


Several early adopter systems have been purchased by customers and installed on buildings in the United States.

        For the fiscal years ended April 30, 2008, 2007 and 2006, our internal research and development spending amounted to 8%, 8% and 12%, respectively, of our revenue, and customer-funded research and development spending amounted to an additional 13%, 11% and 8%, respectively, of our revenue.

Sales and Marketing

        Our marketing strategy is to increase awareness of our brand among key target market segments and to associate AeroVironment with innovation, flexibility, agility and the ability to deliver reliable new technology solutions that improve operational effectiveness. Our reputation for innovation is a key component of our brand and has been acknowledged through a variety of awards and recognized in numerous articles in domestic and international publications. We have registered the trademarks AeroVironment® and PosiCharge® and have submitted several other applications for trademark registration, including for AV, Global Observer and Architectural Wind.

    Small UAS

        We organize our U.S. small UAS business development team members by customer and product and have team members located where they are in close proximity to the customers they support. Supporting our business development team members are our program managers, who are organized by product and focus on designing optimal solutions and contract fulfillment, as well as internalizing feedback from customers and users. By maintaining assigned points of contact with our customers, we believe that we are able to enhance our relationships, service existing contracts effectively and gain vital feedback to improve our responsiveness and product offerings.

    PosiCharge Fast Charge Systems

        We primarily sell our PosiCharge fast charge systems through a dedicated, direct sales force whose members are located in close proximity to the customers they support. The sales team targets large entities with the potential for domestic and international enterprise adoption of our solutions. In addition to our direct customer sales, we also employ a regional sales team that coordinates distribution of PosiCharge fast charge systems through numerous battery dealers. These dealers' relationships with, and proximity to, our customers' facilities enable them to sell our solutions and provide post-sale service to our customers. We believe that these dealers are well suited to address the large number of smaller and geographically dispersed customers with industrial vehicle fleets. When evaluating a facility for its ability to benefit from PosiCharge fast charge systems, we perform a detailed analysis of the customer's operations. This analysis allows us to quantify the benefit projected for a PosiCharge system implementation, helping customers to determine for themselves if the business case is sufficiently compelling.

    International Sales

        We are increasing our sales efforts abroad and have employees in country or have contracted with international sales representatives for our various segments in a variety of foreign markets. Our international sales accounted for approximately 6% of our revenue for the fiscal year ended April 30, 2008.

Manufacturing and Operations

        We pursue a common manufacturing strategy across our product lines, focusing on rapid prototyping, supply chain management, final assembly, quality systems and testing. Using concurrent engineering techniques within an integrated product team structure, we rapidly prototype design

12


concepts and products to produce products at reduced cost and optimize our designs for manufacturing requirements, mission capabilities and customer specifications. Within this framework, we develop our products with feedback and input from manufacturing, supply chain management, key suppliers, logistics personnel and customers. We rapidly incorporate this feedback and input into the design before tooling is finalized and full-rate production begins. As a result, we believe that we can significantly reduce the time required to move a product from its design phase to full-rate production deliveries with high reliability, quality and yields.

        We outsource certain production activities, such as the fabrication of structures and the manufacture of subassemblies and payloads, to qualified suppliers with whom we have long-term relationships. This outsourcing enables us to focus on final assembly and test processes for our products, ensuring high levels of quality and reliability. We believe that our efficient supply chain is a significant strength of our manufacturing strategy. We have forged strong relationships with our key suppliers that we believe will allow us to continue to grow our manufacturing capabilities and execute on our growth plans. We continue to expand upon our suppliers' expertise to improve our existing products and develop new solutions. We rely on both single and multiple suppliers for certain components and subassemblies. See "Risk Factors—If critical components of our products that we currently purchase from a small number of suppliers or raw materials used to manufacture our products become scarce or unavailable then we may incur delays in manufacturing and delivery of our products, which could damage our business" for more information. All of our manufacturing operations incorporate quality programs and processes to increase acceptance rates, reduce lead times and lower cost.

    UAS Manufacturing and Operations

        We have successfully developed the manufacturing infrastructure to execute production of both new small UAS products at low initial rates and high-volume, full-rate production small UAS programs. For example, in 2003, we invested in the infrastructure necessary to transition from low-rate prototype small UAS production to full-rate production, successfully increasing production from 15 aircraft per month to 200 per month in only six months to meet customer demand. By drawing upon experienced personnel from our PosiCharge and Energy Technology Center groups and levering our prior ISO certification, integrated supply chain strategy, document control systems, and process control methodologies into this new manufacturing effort, we laid the groundwork for a high volume, efficient production environment. Presently, our small UAS manufacturing is performed at our 85,000 square foot manufacturing facility established in 2005 in Simi Valley, California. This ISO 9001:2000 certified manufacturing facility is designed to accommodate demand of up to 1,000 aircraft per month. ISO 9001:2000 refers to a set of voluntary standards for quality management systems. These standards are established by the International Organization for Standardization, or ISO, to govern quality management systems used worldwide. Companies that receive ISO certification have passed audits performed by a Registrar Accreditation Board-certified auditing company. These audits evaluate the effectiveness of companies' quality management systems and their compliance with ISO standards. Some companies and government agencies view ISO certification as a positive factor in supplier assessments.

    PosiCharge Systems and Energy Technology Center Manufacturing and Operations

        We perform final assembly and testing of our PosiCharge fast charge systems and power processing products at a 20,000 square foot, ISO 9001:2000 certified facility located in Monrovia, California. We designed this facility for flexibility, using a work cell model for final assembly, and have included fixtures optimized for final testing.

Competition

        We believe that the principal competitive factors in the markets for our products and services include product performance, features, acquisition cost, lifetime operating cost, including maintenance and support, ease of use, integration with existing equipment, quality, reliability, customer support, brand and reputation.

        The market for small UAS is evolving rapidly and subject to changing technologies, shifting customer needs and expectations and the potential introduction of new products. We believe that a number of established domestic and international defense contractors have developed or are developing small UAS that have and will continue to compete directly with our products. Some of these contractors have significantly more financial and other resources than we possess. Our current principal small UAS competitors include Elbit Systems Ltd., L-3 Communications Holdings Inc. and Lockheed Martin Corporation. We do not view large UAS such as Northrop Grumman Corporation's Global Hawk, General Atomics, Inc.'s Predator, The Boeing Company's ScanEagle and AAI Corporation's Shadow as direct competitors to our small UAS because they perform different missions and are not hand launched and controlled, although we cannot be certain that these platforms will not become direct competitors in the future.

        The primary direct competitors to PosiCharge fast charge systems are other fast charge suppliers, including Aker Wade Power Technologies LLC and PowerDesigners, LLC. Some of the major industrial battery suppliers have begun to align themselves with fast charge suppliers, creating a potentially more significant source of competition.

        In addition, our PosiCharge fast charge systems compete against the traditional method of battery changing. Competitors in this area include suppliers of battery changing equipment and infrastructure, designers of battery changing rooms, battery manufacturers and dealers who may experience reduced sales volume because PosiCharge fast charge systems reduces or eliminate the need for extra batteries.

Regulation

        Due to the fact that we contract with the DoD and other agencies of the U.S. government, we are subject to extensive federal regulations, including the Federal Acquisition Regulations, Defense Federal Acquisitions Regulations, Truth in Negotiations Act, Foreign Corrupt Practices Act, False Claims Act and the regulations promulgated under the DoD Industrial Security Manual, which establishes the security guidelines for classified programs and facilities as well as individual security clearances. The federal government audits and reviews our performance on contracts, pricing practices, cost structure, and compliance with applicable laws, regulations, and standards. Like most government contractors, our contracts are audited and reviewed on a continual basis by federal agencies, including the Defense Contract Management Agency, or DCMA and the Defense Contract Audit Agency, or DCAA.

        Certain of these regulations carry substantial penalty provisions, including suspension or debarment from government contracting or subcontracting for a period of time if we are found to be in violation. We carefully monitor all of our contracts and contractual efforts to minimize the possibility of any violation of these regulations.

        In addition, due to the nature of the products and services we provide, we are subject to further U.S. government regulation, including by the Federal Aviation Administration, or FAA, which regulates airspace for all air vehicles, by the National Telecommunications and Information Administration and Federal Communications Commission, which regulate the wireless communications upon which our small UAS depend, and under the International Traffic in Arms Regulations, which regulate the export of controlled technical data, defense articles and defense services. In 2006, the FAA issued a clarification of its existing policies stating that, in order to engage in public use of small UAS in the U.S. National Airspace System, a public (government) operator must obtain a Certificate of

14


Authorization, or COA, from the FAA or fly in restricted airspace. The FAA's COA approval process requires that the public operator certify the airworthiness of the aircraft for its intended purpose, that a collision with another aircraft or other airspace user is extremely improbable, that the small UAS complies with appropriate cloud and terrain clearances and that the operator or spotter of the small UAS is generally within one half-mile laterally and 400 feet vertically of the small UAS while in operation. Furthermore, the FAA's clarification of existing policy states that the rules for radio-controlled hobby aircraft do not apply to public or commercial use of small UAS. The FAA is in the process of drafting updated regulations specifically for small UAS operations. We have engaged in discussions with the FAA to help ensure that these new regulations allow for the maximum safe utilization of our small UAS.

        Furthermore, our non-U.S. operations are subject to the laws and regulations of foreign jurisdictions, which may include regulations that are more stringent than those imposed by the U.S. government on our U.S. operations.

    Government Contracting Process

        We sell the significant majority of our small UAS products and services as the prime contractor under contracts with the U.S. government. Certain important aspects of our government contracts are described below.

    Bidding Process

        We are awarded government contracts either on a sole-source basis or through a competitive bidding process. Most of our current government contracts were awarded through a competitive bidding process. The U.S. government awards competitive-bid contracts based on proposal evaluation criteria established by the procuring agency. Competitive-bid contracts are awarded after a formal bid and proposal competition among providers. Interested contractors prepare a bid and proposal in response to the agency's request for proposal or request for information. A bid and proposal is usually prepared in a short time period in response to a deadline and requires the extensive involvement of numerous technical and administrative personnel. Following award, competitive-bid contracts may be challenged by unsuccessful bidders.

    Funding

        The funding of U.S. government programs is subject to congressional appropriations. Although multi-year contracts may be authorized in connection with major procurements, Congress generally appropriates funds on a fiscal year basis, even though a program may continue for many years. Consequently, programs are often only partially funded initially, and additional funds are committed only as Congress makes further appropriations.

        The contracts for our full-rate production UAS are funded either through operational needs statements or as programs of record. Operational needs statements represent allocations of discretionary spending or reallocations of funding from other government programs. Funding for our production of initial Raven deliveries was provided through operational needs statements. We define a program of record as a program which, after undergoing extensive DoD review and product testing, is included in the five-year government budget cycle, meaning that funding will be allocated for purchases under these contracts during the five-year cycle, absent affirmative action by the customer or Congress to change the budgeted amount. Funding for these programs is approved annually.

15

        We are currently the sole provider and prime contractor under the only three programs of record established by the DoD for small UAS. Each of the following contracts was awarded under a program of record through a competitive bidding process:

    Our 2005 contract for Raven B, our next generation Raven product, awarded under a U.S. Army/U.S. Special Operations Command, or USSOCOM, program of record known as the Small Unmanned Aerial System program, provides for purchases of up to $358.2 million through 2010 and also allows for contract additions from the U.S. Army/SOCOM or other U.S. military services. As of April 30, 2008, orders in the amount of approximately $225.2 million had been placed with us.

    Our 2003 contract for Dragon Eye, awarded under a U.S. Marine Corps program of record known as the Small Unit Remote Scouting System, or SURSS, program, provides for purchases of up to $50.0 million through 2008. As of April 30, 2008, orders in the amount of approximately $47.8 million had been placed with us.

    Our 2006 contract for Block III Wasp, or BATMAV, awarded under a U.S. Air Force program of record known as the Beyond Line of Site program, provides for purchases of up to $45.0 million over a period of five years. As of April 30, 2008, orders in the amount of approximately $29.2 million had been placed with us.

    Material Government Contract Provisions

        All contracts with the U.S. government contain provisions, and are subject to laws and regulations, that give the government rights and remedies not typically found in commercial contracts, including rights that allow the government to:

    terminate existing contracts for convenience, which affords the U.S. government the right to terminate the contract in whole or in part anytime it wants for any reason or no reason, as well as for default;

    reduce or modify contracts or subcontracts, if its requirements or budgetary constraints change;

    cancel multi-year contracts and related orders, if funds for contract performance for any subsequent year become unavailable;

    claim rights in products and systems produced by its contractors if the contract is cost reimbursable and the contractor produces the products or systems during the performance of the contract;

    adjust contract costs and fees on the basis of audits completed by its agencies;

    suspend or debar a contractor from doing business with the U.S. government; and

    control or prohibit the export of products.

        Generally, government contracts are subject to oversight audits by government representatives. Provisions in these contracts permit termination, in whole or in part, without prior notice, at the government's convenience or upon contractor default under the contract. Compensation in the event of a termination, if any, is limited to work completed at the time of termination. In the event of termination for convenience, the contractor may receive a certain allowance for profit on the work performed.

    Government Contract Categories

        We have three types of government contracts, each of which involves a different payment methodology and level of risk related to the cost of performance. These basic types of contracts are

16

typically referred to as fixed-price contracts, cost reimbursable contracts (including cost-plus-fixed fee, cost-plus-award fee, and cost-plus-incentive fee) and time-and-materials contracts.

        In some cases, depending on the urgency of the project and the complexity of the contract negotiation, we will enter into a Letter Contract prior to finalizing the terms of a definitive fixed-price, cost reimbursable or time-and-materials definitive contract. A Letter Contract is a written preliminary contractual instrument that provides limited initial funding and authorizes us to begin immediately manufacturing supplies or performing services while negotiating the definitive terms of the procurement.

        Fixed-Price.    These contracts are not subject to adjustment by reason of costs incurred in the performance of the contract. With this type of contract, we assume the risk that we will not be able to perform at a cost below the fixed-price, except for costs incurred because of contract changes ordered by the customer. Upon the U.S. government's termination of a fixed-price contract, generally we would be entitled to payment for items delivered to and accepted by the U.S. government and, if the termination is at the U.S. government's convenience, for payment of fair compensation for work performed plus the costs of settling and paying claims by any terminated subcontractors, other settlement expenses and a reasonable allowance for profit on the costs incurred.

        Cost Reimbursable.    Cost reimbursable contracts include cost-plus-fixed fee contracts, cost-plus-award fee contracts and cost-plus-incentive fee contracts. Under each type of contract, we assume the risk that we may not be able to recover costs if they are not allowable under the contract terms or applicable regulations, or if the costs exceed the contract funding.

    Cost-plus-fixed fee contracts are cost reimbursable contracts that provide for payment of a negotiated fee that is fixed at the inception of the contract. This fixed fee does not vary with actual cost of the contract, but may be adjusted as a result of changes in the work to be performed under the contract. This contract type poses less risk of loss than a fixed-price contract, but our ability to win future contracts from the procuring agency may be adversely affected if we fail to perform within the maximum cost set forth in the contract.

    A cost-plus-award fee contract is a cost reimbursable contract that provides for a fee consisting of a base amount (which may be zero) fixed at inception of the contract and an award amount, based upon the government's satisfaction with the performance under the contract. With this type of contract, we assume the risk that we may not receive the award fee, or only a portion of it, if we do not perform satisfactorily.

    A cost-plus-incentive fee contract is a cost reimbursable contract that provides for an initially negotiated fee to be adjusted later by a formula based on the relationship of total allowable costs to total target costs.

        We typically experience lower profit margins and lower risk under cost reimbursable contracts than under fixed-price contracts. Upon the termination of a cost reimbursable contract, generally we would be entitled to reimbursement of our allowable costs and, if the termination is at the U.S. government's convenience, a total fee proportionate to the percentage of work completed under the contract.

        Time-and-Materials.    Under a time-and-materials contract, our compensation is based on a fixed hourly rate established for specified labor or skill categories. We are paid at the established hourly rates for the hours we expend performing the work specified in the contract. Labor costs, overhead, general and administrative costs and profit are included in the fixed hourly rate. Materials, subcontractors, travel and other direct costs are reimbursed at actual costs plus an amount for material handling. We make critical pricing assumptions and decisions when developing and proposing time-and-materials labor rates. We risk reduced profitability if our actual costs exceed the costs incorporated into the fixed hourly labor rate. One variation of a standard time-and-materials contract is

17


a time-and-materials, award fee contract. Under this type of contract, a positive or negative incentive can be earned based on achievement against specific performance metrics.

    Indefinite Delivery Indefinite Quantity Contract Form

        The U.S. government frequently uses indefinite delivery, indefinite quantity contracts, known as IDIQ contracts, and IDIQ-type contract forms such as cost reimbursable and fixed price contracts with multiple one-year options, to obtain fixed-price, cost reimbursable and time-and-materials contractual commitments to provide products or services over a period of time pursuant to established general terms and conditions. At the time of the award of an IDIQ contract or IDIQ-type contract, the U.S. Government generally commits to purchase only a minimal amount of products or services from the contractor to whom such contract is awarded.

        After award of an IDIQ contract, the U.S. Government may issue task orders for specific services or products it needs. The competitive process to obtain task orders under an award contract is limited to the pre-selected contractors. If such contract has a single prime contractor, then the award of task orders is limited to that contractor. If the contract has multiple prime contractors, then the award of the task order is competitively determined among only those prime contractors.

        IDIQ and IDIQ-type contracts typically have multi-year terms and unfunded ceiling amounts which enable, but do not commit, the U.S. government to purchase substantial amounts of products and services from one or more contractors.

Contract Mix

        The table below shows our revenue for the periods indicated by contract type, including both government and commercial sales:

 
  Fiscal Year Ended

Item 1A.    Risk Factors.

We rely heavily on sales to the U.S. government, particularly to agencies of the Department of Defense.

        Historically, a significant portion of our total sales and substantially all of our small UAS sales have been to the U.S. government and its agencies. Sales to the U.S. government, either as a prime contractor or subcontractor, represented approximately 84% of our revenue for the fiscal year ended April 30, 2008. The DoD, our principal U.S. government customer, accounted for approximately 80% of our revenue for the fiscal year ended April 30, 2008. We believe that the success and growth of our business for the foreseeable future will continue to depend on our ability to win government contracts, in particular from the DoD. Many of our government customers are subject to budgetary constraints and our continued performance under these contracts, or award of additional contracts from these agencies, could be jeopardized by spending reductions or budget cutbacks at these agencies. The funding of U.S. government programs is uncertain and dependent on continued congressional appropriations and administrative allotment of funds based on an annual budgeting process. We cannot assure you that current levels of congressional funding for our products and services will continue. Furthermore, all of our contracts with the U.S. government are terminable by the U.S. government at will. A significant decline in government expenditures generally, or with respect to programs for which we provide products, could adversely affect our business and prospects. Our operating results may also be negatively impacted by other developments that affect these government programs generally, including the following:

    changes in government programs that are related to our products and services;

    adoption of new laws or regulations relating to government contracting or changes to existing laws or regulations;

    changes in political or public support for security and defense programs;

    delays or changes in the government appropriations process;

    uncertainties associated with the war on terror and other geo-political matters; and

    delays in the payment of our invoices by government payment offices.

        These developments and other factors could cause governmental agencies to reduce their purchases under existing contracts, to exercise their rights to terminate contracts at-will or to abstain from renewing contracts, any of which would cause our revenue to decline and could otherwise harm our business, financial condition and results of operations.

Military transformation and operational levels in Afghanistan and Iraq may affect future procurement priorities and existing programs, which could limit demand for our UAS.

        Following the end of the Cold War, the U.S. military began a transformation of its operational concepts, organizational structure and technologies in an effort to improve warfighting capabilities. The resulting shift in procurement priorities toward achieving these capabilities, together with the current high level of operational activity in Afghanistan and Iraq, have led to an increase in demand for our

19


small UAS. We cannot predict whether current or future changes in priorities due to defense transformation or continuation of the current nature and magnitude of operations in Afghanistan and Iraq will afford new opportunities for our small UAS business in terms of existing, additional or replacement programs. Furthermore, we cannot predict whether or to what extent this defense transformation or current operational levels in Afghanistan or Iraq will continue. If defense transformation or operations in Afghanistan and Iraq cease or slow down, then our business, financial condition and results of operations could be impacted.

We operate in evolving markets, which makes it difficult to evaluate our business and future prospects.

        UAS, fast charge systems and other energy technologies that we offer are sold in new and rapidly evolving markets. Accordingly, our business and future prospects are difficult to evaluate. We cannot accurately predict the extent to which demand for our products will increase, if at all. The challenges, risks and uncertainties frequently encountered by companies in rapidly evolving markets could impact our ability to do the following:

    generate sufficient revenue to maintain profitability;

    acquire and maintain market share;

    manage growth in our operations;

    develop and renew contracts;
