PROSPECTUS SUMMARY

	•	Expand our current solutions to existing and new customers.  Our small UAS and PosiCharge products 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 militaries 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 to existing and new customers in North America and globally. Early adopters of PosiCharge are now deploying it in additional

		facilities throughout their enterprises while its adoption is increasing among new customers and new industry segments, such as food and logistics.

	•	Deliver innovative solutions.  Innovation is the primary driver of our growth. We plan to continue research and development efforts to enable us to satisfy our customers through better, more capable products and services, both in response to and in anticipation of their 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 and better-funded competitors.

Investing in our common stock involves a high degree of risk. You should carefully consider the following risk factors, as well as the other information in this prospectus, before deciding whether to invest in our common stock. If any of the following risks actually materializes, then our business, financial condition and results of operations would suffer. The trading price of our common stock could decline as a result of any of these risks, and you might lose all or part of your investment in our common stock. You should read the section entitled “Special Note Regarding Forward-Looking Statements” immediately following these risk factors for a discussion of what types of statements are forward-looking statements, as well as the significance of such statements in the context of this prospectus.

 

Risks Related to Our Business

 

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 82% of our revenue for the fiscal year ended April 30, 2006. The U.S. Department of Defense, or DoD, our principal U.S. government customer, accounted for approximately 77% of our revenue for the fiscal year ended April 30, 2006. 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:

 

 

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 unmanned aircraft systems.

 

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 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 harmed.

 

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

 

Unmanned aircraft systems, 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. Prior to investing, you should consider the challenges, risks and uncertainties frequently encountered by companies in rapidly evolving markets. These challenges include our ability to do the following:

 

 

If we fail to address these and other challenges, risks and uncertainties successfully, our business, results of operations and financial condition would be materially harmed.

 

We face competition from other firms, many of which have substantially greater resources.

 

The defense industry is highly competitive and generally characterized by intense competition to win contracts. Our current principal small UAS competitors include Advanced Ceramics Research, Inc., Applied Research Associates, Inc., 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 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. Some of these firms have substantially greater financial, management, research and marketing resources than we have. The primary direct competitors to our PosiCharge business are other fast charge suppliers, including Aker Wade Power Technologies LLC, Minit-Charger, a subsidiary of Edison International, and PowerDesigners, LLC, as well as industrial battery

manufacturers who distribute fast charge systems from these suppliers. Our competitors may be able to provide customers with different or greater capabilities or benefits than we can provide in areas such as technical qualifications, past contract performance, geographic presence, price and the availability of key professional personnel, including those with security clearances. Furthermore, many of our competitors may be able to utilize their substantially greater resources and economies of scale to develop competing products and technologies, divert sales away from us by winning broader contracts or hire away our employees by offering more lucrative compensation packages. In the event that the market for unmanned aircraft systems, or UAS, expands, we expect that competition will intensify as additional competitors enter the market and current competitors expand their product lines. In order to secure contracts successfully when competing with larger, well-financed companies, we may be forced to agree to contractual terms that provide for lower aggregate payments to us over the life of the contract, which could adversely affect our margins. In addition, larger diversified competitors serving as prime contractors may be able to supply underlying products and services from affiliated entities, which would prevent us from competing for subcontracting opportunities on these contracts. Our failure to compete effectively with respect to any of these or other factors could have a material adverse effect on our business, prospects, financial condition or operating results.

 

If the unmanned aircraft systems and fast charge systems markets do not experience significant growth, if we cannot expand our customer base or if our products do not achieve broad acceptance, then we will not be able to achieve our anticipated level of growth.

 

For the fiscal year ended April 30, 2006, unmanned aircraft systems and fast charge systems accounted for 80% and 14% of our total revenue, respectively. We cannot accurately predict the future growth rates or sizes of these markets. Demand for these types of systems may not increase, or may decrease, either generally or in specific markets, for particular types of products or during particular time periods. Moreover, there are only a limited number of major programs under which the U.S. military, our primary customer, is currently funding the development or purchase of unmanned aircraft systems. Although we are seeking to expand our customer base to include foreign governments, domestic non-military agencies and commercial customers, we cannot assure you that our efforts will be successful. The expansion of the unmanned aircraft systems and fast charge systems markets in general, and the market for our products in particular, depends on a number of factors, including the following:

 

 

Even if unmanned aircraft systems and fast charge systems gain wide market acceptance, our products may not adequately address market requirements and may not continue to gain market acceptance. If these types of systems generally, or our products specifically, do not gain wide market acceptance, then we may not be able to achieve our anticipated level of growth and our revenue and results of operations would suffer.

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.

 

We obtain hardware components and various subsystems from a limited group of suppliers. We do not have long-term agreements with any of these suppliers that obligate them to continue to sell components or products to us. For example, L-3 Communications Holdings Inc., which is one of our competitors, and Rockwell Collins are currently the sole suppliers of our downlink transmitters/receivers and GPS modules, respectively, for several of our small UAS products, including Raven. In addition, Miller Electric is the sole supplier of the power sources for the PosiCharge ELT product line, and Bruno Bassi is the sole supplier of the PosiCharge SVS product line. We also have several sole suppliers of PosiCharge components and subsystems, such as Accurate Electronics, which supplies multiple items, including display panels and power stages. Our reliance on these suppliers involves significant risks and uncertainties, including whether our suppliers will provide an adequate supply of required components of sufficient quality, will increase prices for the components and will perform their obligations on a timely basis.

 

In addition, certain raw materials and components used in the manufacture of our products are periodically subject to supply shortages, and our business is subject to the risk of price increases and periodic delays in delivery. For example, the airframes for our small UAS are made from certain nylon composites, which experienced restrictions in available supply in 2005 due to increased worldwide demand. Similarly, the market for electronic components is subject to cyclical reductions in supply. If we are unable to obtain components from third-party suppliers in the quantities and of the quality that we require, on a timely basis and at acceptable prices, then we may not be able to deliver our products on a timely or cost-effective basis to our customers, which could cause customers to terminate their contracts with us, increase our costs and seriously harm our business, results of operations and financial condition. Moreover, if any of our suppliers become financially unstable, then we may have to find new suppliers. It may take several months to locate alternative suppliers, if required, or to redesign our products to accommodate components from different suppliers. We may experience significant delays in manufacturing and shipping our products to customers and incur additional development, manufacturing and other costs to establish alternative sources of supply if we lose any of these sources or are required to redesign our products. We cannot predict if we will be able to obtain replacement components within the time frames that we require at an affordable cost, if at all.

 

Any efforts to expand our product offerings beyond our current markets may not succeed, which could negatively impact our operating results.

 

We have focused on selling our small unmanned aircraft systems to the U.S. military and our fast charge systems to large industrial electric vehicle fleet operators primarily in North America. We plan, however, to seek to expand our unmanned aircraft systems sales into other government and commercial markets and our fast charge systems sales into international markets. Efforts to expand our product offerings beyond the markets that we currently serve may divert management resources from existing operations and require us to commit significant financial resources to unproven businesses that may not generate additional sales, either of which could significantly impair our operating results.

 

Our failure to obtain necessary regulatory approvals from the Federal Aviation Administration may prevent us from expanding the sales of our small UAS to non-military customers in the United States and require us to incur additional costs in the testing of our products.

 

Regulations of the Federal Aviation Administration, or FAA, currently require that small UAS comply with the rules for radio-controlled hobby aircraft. These rules require small UAS to maintain flight altitude within 400 feet above the ground, and operators to maintain line of sight with the aircraft

at all times it is in flight. These regulations prevent or inhibit the use of our small UAS in certain civil and commercial applications. The FAA is in the process of drafting updated regulations specifically for small UAS operations, but we cannot assure you that these regulations will allow the use of our small UAS by potential civilian and commercial customers. If the FAA does not modify its regulations to enable the civilian and commercial use of small UAS, we may not be able to expand our sales of UAS beyond our military customers, which could harm our business prospects.

 

Recently, the Defense Contract Management Agency, or DCMA, informed us that, under the terms of our DoD contracts, the government parties with whom we are contracting are required to obtain a certificate of authorization for flight tests of our small UAS outside of military installations. If our DoD customers are unable to obtain such a certificate, we may not be able to perform our flight tests without incurring the additional costs of transporting our small UAS products to military installations, which could impair our operating results.

 

The markets in which we compete are characterized by rapid technological change, which requires us to develop new products and product enhancements, and could render our existing products obsolete.

 

Continuing technological changes in the market for our products could make our products less competitive or obsolete, either generally or for particular applications. Our future success will depend upon our ability to develop and introduce a variety of new capabilities and enhancements to our existing product offerings, as well as introduce a variety of new product offerings, to address the changing needs of the markets in which we offer our products. Delays in introducing new products and enhancements, the failure to choose correctly among technical alternatives or the failure to offer innovative products or enhancements at competitive prices may cause existing and potential customers to purchase our competitors’ products.

 

If we are unable to devote adequate resources to develop new products or cannot otherwise successfully develop new products or enhancements that meet customer requirements on a timely basis, our products could lose market share, our revenue and profits could decline, and we could experience operating losses.

 

We expect to incur substantial research and development costs and devote significant resources to identifying and commercializing new products, which could significantly reduce our profitability and may never result in revenue to us.

 

Our future growth depends on penetrating new markets, adapting existing products to new applications, and introducing new products that achieve market acceptance. We plan to incur substantial research and development costs as part of our efforts to design, develop and commercialize new products and enhance existing products. We spent $16.1 million, or 12% of our revenue, in fiscal year 2006 on research and development activities and expect to continue to spend significant funds on research and development in the future. We expect to utilize a portion of the proceeds of this offering and cash flow from operations to fund our research and development, although we may also utilize borrowings or other external funding in the future. Because we account for research and development as an operating expense, these expenditures will adversely affect our earnings in the future. Further, our research and development program may not produce successful results, and our new products may not achieve market acceptance, create additional revenue or become profitable, which could materially harm our business, prospects, financial results and liquidity.

 

If we are unable to manage our growth, our business could be adversely affected.

 

Our headcount and operations have grown rapidly. This rapid growth has placed, and will continue to place, a significant strain on our management and our administrative, operational and financial infrastructure. From January 2004 through October 2006, we nearly doubled the number of our employees. We anticipate further growth of headcount and facilities will be required to address

increases in our product offerings and the geographic scope of our customer base. Our success will depend in part upon the ability of our senior management to manage this growth effectively. To do so, we must continue to hire, train, manage and integrate a significant number of qualified managers and engineers. If our new employees perform poorly, or if we are unsuccessful in hiring, training, managing and integrating these new employees, or retaining these or our existing employees, then our business may suffer.

 

For us to continue our growth, we must continue to improve our operational, financial and management information systems. If we are unable to manage our growth while maintaining our quality of service, or if new systems that we implement to assist in managing our growth do not produce the expected benefits, then our business, prospects, financial condition or operating results could be adversely affected.

 

Our earnings and profit margins may decrease based on the mix of our contracts and programs and other factors related to our contracts.

 

In general, we perform our production work under fixed-price contracts and our repair and customer-funded research and development work under cost-plus-fee contracts. Under fixed-price contracts, we perform services under a contract at a stipulated price. Under cost-plus-fee contracts, which are subject to a contract ceiling amount, we are reimbursed for allowable costs and paid a fee, which may be fixed or performance based. We typically experience lower profit margins under cost-plus-fee contracts than under fixed-price contracts, though fixed-price contracts have higher risks. In general, if the volume of services we perform under cost-plus-fee contracts increases relative to the volume of services we perform under fixed-price contracts, we expect that our operating margin will suffer. In addition, our earnings and margins may decrease depending on the costs we incur in contract performance, our achievement of other contract performance objectives and the stage of our performance at which our right to receive fees, particularly under incentive and award fee contracts, is finally determined.

 

Our senior management and key employees are important to our customer relationships and overall business.

 

We believe that our success depends in part on the continued contributions of our senior management and key employees. We rely on our executive officers, senior management and key employees to generate business and execute programs successfully. In addition, the relationships and reputation that members of our management team and key employees have established and maintain with government defense personnel contribute to our ability to maintain good customer relations and to identify new business opportunities. We do not have employment agreements with any of our executive officers or key employees, and these individuals could terminate their employment with us at any time. The loss of any of our executive officers, members of our senior management team or key employees could significantly delay or prevent the achievement of our business objectives and could materially harm our business and customer relationships and impair our ability to identify and secure new contracts and otherwise manage our business.

 

We must recruit and retain highly-skilled employees to succeed in our competitive business.

 

We depend on our ability to recruit and retain employees who have advanced engineering and technical services skills and who work well with our customers. These employees are in great demand and are likely to remain a limited resource in the foreseeable future. If we are unable to recruit and retain a sufficient number of these employees, then our ability to maintain our competitiveness and grow our business could be negatively affected. In addition, because of the highly technical nature of our products, the loss of any significant number of our existing engineering personnel could have a material adverse effect on our business and operating results. Moreover, some of our U.S. government contracts contain provisions requiring us to staff a program with certain personnel the customer

considers key to our successful performance under the contract. In the event we are unable to provide these key personnel or acceptable substitutes, the customer may terminate the contract.

 

Our business may be dependent upon our employees obtaining and maintaining required security clearances.

 

Certain of our U.S. government contracts require our employees to maintain various levels of security clearances, and we are required to maintain certain facility security clearances complying with DoD requirements. The DoD has strict security clearance requirements for personnel who work on classified programs. Obtaining and maintaining security clearances for employees involves a lengthy process, and it is difficult to identify, recruit and retain employees who already hold security clearances. If our employees are unable to obtain security clearances in a timely manner, or at all, or if our employees who hold security clearances are unable to maintain the clearances or terminate employment with us, then a customer requiring classified work could terminate the contract or decide not to renew it upon its expiration. In addition, we expect that many of the contracts on which we will bid will require us to demonstrate our ability to obtain facility security clearances and employ personnel with specified types of security clearances. To the extent we are not able to obtain facility security clearances or engage employees with the required security clearances for a particular contract, we may not be able to bid on or win new contracts, or effectively rebid on expiring contracts.

 

Cost overruns on our contracts could subject us to losses, decrease our operating margins and adversely affect our future business.

 

Fixed-price contracts represented approximately 69% of our revenue for the fiscal year ended April 30, 2006. If we fail to anticipate technical problems, estimate costs accurately or control costs during our performance of fixed-price contracts, then we may incur losses on these contracts because we absorb any costs in excess of the fixed price. Under cost-plus-fee contracts, if costs exceed the contract ceiling or are not allowable under the provisions of the contract or applicable regulations, then we may not be able to obtain reimbursement for all such costs. Under time and materials contracts, we are paid for labor at negotiated hourly billing rates and for certain expenses. Under each type of contract, if we are unable to control the costs we incur in performing under the contract, then our financial condition and results of operations could be materially adversely affected. Cost overruns also may adversely affect our ability to sustain existing programs and obtain future contract awards.

 

Our products are complex and could have unknown defects or errors, which may give rise to claims against us, diminish our brand or divert our resources from other purposes.

 

Our unmanned aircraft systems rely on complex avionics, sensors, user-friendly interfaces and tightly-integrated, electromechanical designs to accomplish their missions, and our fast charge systems and energy systems often rely upon the application of intellectual property for which there may have been little or no prior commercial application. Despite testing, our products have contained defects and errors and may in the future contain defects, errors or performance problems when first introduced, when new versions or enhancements are released, or even after these products have been used by our customers for a period of time. These problems could result in expensive and time-consuming design modifications or warranty charges, delays in the introduction of new products or enhancements, significant increases in our service and maintenance costs, exposure to liability for damages, damaged customer relationships and harm to our reputation, any of which could materially harm our results of operations and ability to achieve market acceptance. In addition, increased development and warranty costs could be substantial and could reduce our operating margins.

 

The existence of any defects, errors, or failures in our products or the misuse of our products could also lead to product liability claims or lawsuits against us. A defect, error or failure in one of our unmanned aircraft systems could result in injury, death or property damage and significantly damage our reputation and support for unmanned aircraft systems in general. While our fast charge systems include certain safety mechanisms, these systems can deliver up to 600 amps of current in their

application, and the failure, malfunction or misuse of these systems could result in injury or death. Although we maintain insurance policies, we cannot assure you that this insurance will be adequate to protect us from all material judgments and expenses related to potential future claims or that these levels of insurance will be available in the future at economical prices or at all. A successful product liability claim could result in substantial cost to us. Even if we are fully insured as it relates to a claim, the claim could nevertheless diminish our brand and divert management’s attention and resources, which could have a negative impact on our business, financial condition and results of operations.

 

The operation of unmanned aircraft systems in urban environments may be subject to risks, such as accidental collisions and transmission interference, which may limit demand for our unmanned aircraft systems in such environments and harm our business and operating results.

 

Urban environments may present certain challenges to the operators of unmanned aircraft systems. Unmanned aircraft systems may accidentally collide with other aircraft, persons or property, which could result in injury, death or property damage and significantly damage the reputation of and support for unmanned aircraft systems in general. While we are aware of only one instance of an accidental collision involving an unmanned aircraft system to date, as the usage of unmanned aircraft systems has increased, particularly by military customers in urban areas of Afghanistan and Iraq, the danger of such collisions has increased. Furthermore, the number of unmanned aircraft systems that can operate simultaneously in a given geographic area is limited by the allocated frequency spectrum available. In addition, obstructions to effective transmissions in urban environments, such as large buildings, may limit the ability of the operator to utilize the aircraft for its intended purpose. The risks or limitations of operating unmanned aircraft systems in urban environments may limit their value in such environments, which may limit demand for our unmanned aircraft systems and consequently materially harm our business and operating results.

 

Our quarterly operating results may vary widely.

 

Our quarterly revenue, cash flow and operating results have and may continue to fluctuate significantly in the future due to a number of factors, including the following:

 

 

 

 

Changes in the volume of products and services provided under existing contracts and the number of contracts commenced, completed or terminated during any quarter may cause significant

variations in our cash flow from operations because a relatively large amount of our expenses are fixed. We incur significant operating expenses during the start-up and early stages of large contracts and typically do not receive corresponding payments in that same quarter. We may also incur significant or unanticipated expenses when contracts expire or are terminated or are not renewed. In addition, payments due to us from government agencies may be delayed due to billing cycles or as a result of failures of governmental budgets to gain congressional and presidential administration approval in a timely manner.

 

Shortfalls in available external research and development funding could adversely affect us.

 

We depend on our research and development activities to develop the core technologies used in our small UAS and PosiCharge products and for the development of our future products. A portion of our research and development activities depends on funding by commercial companies and the U.S. government. U.S. government and commercial spending levels can be impacted by a number of variables, including general economic conditions, specific companies’ financial performance and competition for U.S. government funding with other U.S. government-sponsored programs in the budget formulation and appropriation processes. Moreover, the U.S., state and local governments provide energy rebates and incentives to commercial companies, which directly impact the amount of research and development that companies appropriate for energy systems. To the extent that these energy rebates and incentives are reduced or eliminated, company funding for research and development could be reduced. Any reductions in available research and development funding could harm our business, financial condition and operating results.

 

Volatility and cyclicality in the market for electric industrial vehicles could adversely affect us.

 

Our PosiCharge fast charge systems, which accounted for 14% of our revenue during the fiscal year ended April 30, 2006, are purchased primarily by operators of fleets of electric industrial vehicles, such as forklift trucks and airport ground support equipment. Consequently, our ability to remain profitable depends in part on the varying conditions in the market for electric industrial vehicles. This market is subject to volatility as it moves in response to cycles in the overall business environment and is also particularly sensitive to the industrial, food and beverage, retail and air travel sectors, which generate a significant portion of the demand for such vehicles. Sales of electric industrial vehicles have historically been cyclical, with demand affected by such economic factors as industrial production, construction levels, demand for consumer and durable goods, interest rates and fuel costs. A significant decline in demand for electric industrial vehicles could adversely affect our revenue and prospects, which would harm our business, financial condition and operating results.

 

Our fast charge business is dependent upon our relationships with battery dealers and other third parties with whom we do not have exclusive arrangements.

 

To remain competitive in the market for fast charge systems, we must maintain our access to potential customers and ensure that the service needs of our customers are met adequately. In many cases, we rely on battery dealers for access to potential PosiCharge customers. Currently, one of our fast charge system competitors is working with a battery manufacturer to sell fast charge systems and batteries together. Cooperative agreements between our competitors and battery manufacturers could restrict our access to battery dealers and potential PosiCharge customers, adversely affecting our revenue and prospects. Additionally, we rely on outside service providers to perform post-sale services for our PosiCharge customers. If these service providers fail to perform these services as required or discontinue their business with us, then we could lose customers to competitors, which would harm our business, financial condition and operating results.

We work in international locations where there are high security risks, which could result in harm to our employees and contractors or substantial costs.

 

Some of our services are performed in high-risk locations, such as Iraq and Afghanistan, where the country or location is suffering from political, social or economic issues, or war or civil unrest. For example, we currently maintain a forward operating depot in Iraq, located in a U.S. government installation and typically staffed by two or three of our employees. In addition, we have occasionally had one trainer stationed in Kuwait and are obligated, pursuant to one of our contracts, to provide overseas support personnel as needed. Last year, pursuant to this contract, we had three trainers stationed overseas for a period of 30 days. In those locations where we have employees or operations, we may incur substantial costs to maintain the safety of our personnel. Despite these precautions, the safety of our personnel in these locations may continue to be at risk, and we may in the future suffer the loss of employees and contractors, which could harm our business and operating results.

 

We may not be able to obtain capital when desired on favorable terms, if at all, or without dilution to our stockholders.

 

We operate in emerging and rapidly evolving markets, which makes our prospects difficult to evaluate. It is possible that we may not generate sufficient cash flow from operations or otherwise have the capital resources to meet our future capital needs. If this occurs, then we may need additional financing to pursue our business strategies, including to:

 

 

If we raise additional funds through the issuance of equity or convertible debt securities, the percentage ownership of our stockholders could be significantly diluted, and these newly-issued securities may have rights, preferences or privileges senior to those of existing stockholders, including those acquiring shares in this offering. We cannot assure you that additional financing will be available on terms favorable to us, or at all. Our existing line of credit contains, and future debt financing may contain, covenants or other provisions that limit our operational or financial flexibility. In addition, certain of our customers require that we obtain letters of credit to support our obligations under some of our contracts. Our existing letter-of-credit provider requires that we hold cash in an amount equal to the amount of our outstanding letters of credit as collateral. Continued access to letters of credit may be important to our ability to regain and win contracts in the future. If adequate funds are not available or are not available on acceptable terms, if and when needed, then our ability to fund our operations, take advantage of unanticipated opportunities, develop or enhance our products, or otherwise respond to competitive pressures would be significantly limited.

 

Our international business poses potentially greater risks than our domestic business.

 

We derived an average of 3.7% of our revenue from international sales during the three fiscal years ended April 30, 2006, and in the six months ended October 28, 2006, we derived 7.6% of our revenue from international sales. We expect to derive an increasing portion of our revenue from international sales. Our international revenue and operations are subject to a number of material risks, including the following:

 

 

 

Negative developments in any of these areas in one or more countries could result in a reduction in demand for our products, the cancellation or delay of orders already placed, threats to our intellectual property, difficulty in collecting receivables and a higher cost of doing business, any of which could negatively impact our business, financial condition or results of operations. Moreover, our sales, including sales to customers outside the United States, are denominated in dollars, and downward fluctuations in the value of foreign currencies relative to the U.S. dollar may make our products more expensive than other products, which could harm our business.

 

Potential future acquisitions could be difficult to integrate, divert the attention of key personnel, disrupt our business, dilute stockholder value and impair our financial results.

 

We intend to consider strategic acquisitions that would add to our customer base, technological capabilities or system offerings. Acquisitions involve numerous risks, any of which could harm our business, including the following:

 

 

Acquisitions also frequently result in the recording of goodwill and other intangible assets which are subject to potential impairments in the future that could harm our financial results. In addition, if

we finance acquisitions by issuing equity, or securities convertible into equity, then our existing stockholders may be diluted, which could lower the market price of our common stock. If we finance acquisitions through debt, then such future debt financing may contain covenants or other provisions that limit our operational or financial flexibility. As a result, if we fail to properly evaluate acquisitions or investments, then we may not achieve the anticipated benefits of any such acquisitions, and we may incur costs in excess of what we anticipate. The failure to successfully evaluate and execute acquisitions or investments or otherwise adequately address these risks could materially harm our business and financial results.

 

Environmental laws and regulations and unforeseen costs could impact our future earnings.

 

The manufacture and sale of our products in certain states and countries may subject us to environmental and other regulations. For example, we obtain a significant number of our electronics components from companies located in East Asia, where environmental rules may be less stringent than in the United States. Over time, the countries where these companies are located may adopt more stringent environmental regulations, resulting in an increase in our manufacturing costs. Furthermore, certain environmental laws, including the U.S. Comprehensive, Environmental Response, Compensation and Liability Act of 1980, impose strict, joint and several liability on current and previous owners or operators of real property for the cost of removal or remediation of hazardous substances and impose liability for damages to natural resources. These laws often impose liability even if the owner or operator did not know of, or was not responsible for, the release of such hazardous substances. These environmental laws also assess liability on persons who arrange for hazardous substances to be sent to disposal or treatment facilities when such facilities are found to be contaminated. Such persons can be responsible for cleanup costs even if they never owned or operated the contaminated facility. Although we have not yet been named a responsible party at a contaminated site, we could be named a potentially responsible party in the future. We cannot assure you that such existing laws or future laws will not have a material adverse effect on our future earnings or results of operations.

 

Our business and operations are subject to the risks of earthquakes and other natural catastrophic events.

 

Our corporate headquarters, research and development and manufacturing operations are located in Southern California, a region known for seismic activity and wild fires. A significant natural disaster, such as an earthquake, fire or other catastrophic event, could severely affect our ability to conduct normal business operations, and as a result, our future operating results could be materially and adversely affected.

 

Risks Related to Our U.S. Government Contracts

 

We are subject to extensive government regulation, and our failure to comply with applicable regulations could subject us to penalties that may restrict our ability to conduct our business.

 

As a contractor to the U.S. government, we are subject to and must comply with various government regulations that impact our revenue, operating costs, profit margins and the internal organization and operation of our business. The most significant regulations and regulatory authorities affecting our business include the following:

 

 

 

Also, we need special security clearances and regulatory approvals to continue working on certain of our projects with the U.S. government. Classified programs generally will require that we comply with various executive orders, federal laws and regulations and customer security requirements that may include restrictions on how we develop, store, protect and share information, and may require our employees to obtain government security clearances. Our failure to comply with applicable regulations, rules and approvals or misconduct by any of our employees could result in the imposition of fines and penalties, the loss of security clearances, the loss of our government contracts or our suspension or debarment from contracting with the U.S. government generally, any of which would harm our business, financial condition and results of operations. We are also subject to certain regulations of comparable government agencies in other countries, and our failure to comply with these non-U.S. regulations could also harm our business, financial condition or results of operations.

 

Our business could be adversely affected by a negative audit by the U.S. government.

 

U.S. government agencies, primarily the Defense Contract Audit Agency and the Defense Contract Management Agency, routinely audit and investigate government contractors. These agencies review a contractor’s performance under its contracts, cost structure and compliance with applicable laws, regulations and standards. These agencies also may review the adequacy of, and a contractor’s compliance with, its internal control systems and policies, including the contractor’s purchasing, property, estimating, compensation and management information systems. Any costs found to be improperly allocated to a specific contract will not be reimbursed, while such costs already reimbursed must be refunded. If an audit of our business were to uncover improper or illegal activities, then we could be subject to civil and criminal penalties and administrative sanctions, including termination of contracts, forfeiture of profits, suspension of payments, fines and suspension or prohibition from doing business with the U.S. government. In addition, we could suffer serious harm to our reputation if allegations of impropriety or illegal acts were made against us, even if the allegations were inaccurate. If any of the foregoing were to occur, our financial condition and operating results could be materially adversely affected.

 

We were recently audited by the DCMA with respect to our system for the care, control and accountability of government property. The DCMA identified certain corrective actions to be taken with respect to our system, which we have implemented. Although we successfully implemented these corrective actions, we cannot assure you that the DCMA will not require additional corrective actions in the future. The failure to comply with requirements for government contractors in the future would

adversely affect our ability to do business with the U.S. government and could harm our business and operating results.

 

Some of our contracts with the U.S. government allow it to use inventions developed under the contracts and to disclose technical data to third parties, which could harm our ability to compete.

 

Some of our contracts allow the U.S. government to use, royalty-free, or have others use, inventions developed under those contracts on behalf of the government. Some of the contracts allow the federal government to disclose technical data without constraining the recipient on how those data are used. The ability of third parties to use patents and technical data for government purposes creates the possibility that the government could attempt to establish alternative suppliers or to negotiate with us to reduce our prices. The potential that the government may release some of the technical data without constraint creates the possibility that third parties may be able to use this data to compete with us, which could have a material adverse effect on our business, results of operations or financial condition.

 

U.S. government contracts are generally not fully funded at inception and contain certain provisions that may be unfavorable to us, which could prevent us from realizing our contract backlog and materially harm our business and results of operations.

 

DoD contracts typically involve long lead times for design and development, and are subject to significant changes in contract scheduling. Congress generally appropriates funds on a fiscal year basis even though a program may continue for several years. Consequently, programs are often only partially funded initially, and additional funds are committed only as Congress makes further appropriations. The termination or reduction of funding for a government program would result in a loss of anticipated future revenue attributable to that program.

 

As of October 28, 2006, we had funded U.S. government contract backlog of $64.0 million and estimated unfunded U.S. government contract backlog of $491.5 million. The actual receipt of revenue on awards included in backlog may never occur or may change because a program schedule could change or the program could be canceled, or a contract could be reduced, modified or terminated early.

 

In addition, U.S. government contracts generally contain provisions permitting termination, in whole or in part, at the government’s convenience or for contractor default. Since a substantial majority of our revenue is dependent on the procurement, performance and payment under our U.S. government contracts, the termination of one or more critical government contracts could have a negative impact on our results of operations and financial condition. Termination arising out of our default could expose us to liability and have a material adverse effect on our ability to re-compete for future contracts and orders. Moreover, several of our contracts with the U.S. government do not contain a limitation of liability provision, creating a risk of responsibility for indirect, incidental damages and consequential damages. These provisions could cause substantial liability for us, especially given the use to which our products may be put.

 

U.S. government contracts are subject to a competitive bidding process that can consume significant resources without generating any revenue.

 

U.S. government contracts are frequently awarded only after formal, protracted competitive bidding processes and, in many cases, unsuccessful bidders for U.S. government contracts are provided the opportunity to protest contract awards through various agency, administrative and judicial channels. We derive significant revenue from U.S. government contracts that were awarded through a competitive bidding process. Much of the UAS business that we expect to seek in the foreseeable

future likely will be awarded through competitive bidding. Competitive bidding presents a number of risks, including the following:

 

 

We may not be provided the opportunity to bid on contracts that are held by other companies and are scheduled to expire if the government extends the existing contract. If we are unable to win particular contracts that are awarded through a competitive bidding process, then we may not be able to operate in the market for goods and services that are provided under those contracts for a number of years. If we are unable to win new contract awards over any extended period consistently, then our business and prospects will be adversely affected.

 

Risks Related to Our Intellectual Property

 

If we fail to protect, or incur significant costs in defending, our intellectual property and other proprietary rights, our business and results of operations could be materially harmed.

 

Our success depends, in large part, on our ability to protect our intellectual property and other proprietary rights. We rely primarily on patents, trademarks, copyrights, trade secrets and unfair competition laws, as well as license agreements and other contractual provisions, to protect our intellectual property and other proprietary rights. However, a significant portion of our technology is not patented, and we may be unable or may not seek to obtain patent protection for this technology. Moreover, existing U.S. legal standards relating to the validity, enforceability and scope of protection of intellectual property rights offer only limited protection, may not provide us with any competitive advantages, and may be challenged by third parties. The laws of countries other than the United States may be even less protective of intellectual property rights. Accordingly, despite our efforts, we may be unable to prevent third parties from infringing upon or misappropriating our intellectual property or otherwise gaining access to our technology. Unauthorized third parties may try to copy or reverse engineer our products or portions of our products or otherwise obtain and use our intellectual property. Moreover, many of our employees have access to our trade secrets and other intellectual property. If one or more of these employees leave us to work for one of our competitors, then they may disseminate this proprietary information, which may as a result damage our competitive position. If we fail to protect our intellectual property and other proprietary rights, then our business, results of operations or financial condition could be materially harmed.

 

In addition, affirmatively defending our intellectual property rights and investigating whether we are pursuing a product or service development that may violate the rights of others may entail significant expense. We have not found it necessary to resort to legal proceedings to protect our intellectual property, but may find it necessary to do so in the future. Any of our intellectual property rights may be challenged by others or invalidated through administrative processes or litigation. If we resort to legal proceedings to enforce our intellectual property rights or to determine the validity and scope of the intellectual property or other proprietary rights of others, then the proceedings could result in significant expense to us and divert the attention and efforts of our management and technical employees, even if we prevail.

 

We may be sued by third parties for alleged infringement of their proprietary rights, which could be costly, time-consuming and limit our ability to use certain technologies in the future.

 

We may become subject to claims that our technologies infringe upon the intellectual property or other proprietary rights of third parties. Any claims, with or without merit, could be time-consuming and expensive, and could divert our management’s attention away from the execution of our business plan. Moreover, any settlement or adverse judgment resulting from these claims could require us to pay substantial amounts or obtain a license to continue to use the disputed technology, or otherwise restrict or prohibit our use of the technology. We cannot assure you that we would be able to obtain a license from the third party asserting the claim on commercially reasonable terms, if at all, that we would be able to develop alternative technology on a timely basis, if at all, or that we would be able to obtain a license to use a suitable alternative technology to permit us to continue offering, and our customers to continue using, our affected product. An adverse determination also could prevent us from offering our products to others. Infringement claims asserted against us may have a material adverse effect on our business, results of operations or financial condition.

 

Risks Relating to Securities Markets and Investment in Our Stock

 

There may not be a viable public market for our common stock.

 

Prior to this offering, there has been no public market for our common stock, and there can be no assurance that a regular trading market will develop and continue after this offering or that the market price of our common stock will not decline below the initial public offering price. If no trading market develops, then securities analysts may not initiate or maintain research coverage of us which could further depress the market for our common stock. As a result, investors may not be able to sell their common stock at or above the initial public offering price or at the time that they would like to sell. The initial public offering price will be determined through negotiations between us and the representatives of the underwriters and may not be indicative of the market price of our common stock following this offering.

 

Our management, whose interests may not be aligned with yours, is able to control the vote on all matters requiring stockholder approval.

 

As of October 28, 2006, our directors, executive officers and their affiliates collectively beneficially owned           shares, or 84.5%, of our total outstanding shares of common stock. Upon consummation of this offering, our directors, executive officers and their affiliates will collectively beneficially own           shares, or  %, of our total outstanding shares of common stock. Accordingly, both prior and subsequent to consummation of this offering our directors and executive officers as a group may control the vote on all matters requiring stockholder approval, including the election of directors. The interests of our directors and executive officers may not be fully aligned with yours. Although there is no agreement among our directors and executive officers with respect to the voting of their shares, this concentration of ownership may delay, defer or even prevent a change in control of our company, and make transactions more difficult or impossible without the support of all or some of our directors and executive officers. These transactions might include proxy contests, tender offers, mergers or other purchases of common stock that could give you the opportunity to realize a premium over the then-prevailing market price for shares of our common stock.

 

Market volatility may affect our stock price and the value of your investment.

 

Following this offering, the market price for our common stock is likely to be volatile, in part because our shares have not been traded publicly. The market prices for securities of emerging technology companies have historically been highly volatile, and the market has from time to time experienced significant price and volume fluctuations that are unrelated to the operating performance of particular companies. The market price of our common stock may fluctuate significantly in response to a number of factors, most of which we cannot control, including the following:

 

 

 

In addition, the equity markets in general, and Nasdaq in particular, have experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of those companies. Further, the market prices of securities of emerging technology companies have been particularly volatile. These broad market and industry factors may affect the market price of our common stock adversely, regardless of our operating performance. In the past, following periods of volatility in the market price of a company’s securities, securities class action litigation often has been instituted against that company. This type of litigation, if instituted against us, could result in substantial costs and a diversion of management’s attention and resources.

 

Future sales of our common stock may depress our stock price.

 

After completion of this offering, we will have           shares of common stock outstanding. The shares sold in this offering, or           shares if the underwriters’ over-allotment is exercised in full, will be freely tradable without restriction or further registration under federal securities laws unless purchased by our “affiliates” as such term is used in Rule 144 of the Securities Act of 1933, as amended, or Securities Act.           shares of common stock outstanding after completion of this offering, based upon shares outstanding as of October 28, 2006, will be available for sale in the public market as of the date of this prospectus. After the lock-up agreements pertaining to this offering expire, up to an additional           shares of our common stock will be eligible for sale in the public market,           of which are held by executive officers, directors and other affiliates and will be subject to volume limitations under Rule 144 of the Securities Act.

 

The above information assumes the effectiveness of the lock-up agreements under which current holders of our common stock and all of our officers and directors have agreed not to sell or otherwise dispose of their shares of common stock. Goldman, Sachs & Co., on behalf of the underwriters, may, in its sole discretion and at any time without notice, release all or any portion of the securities subject to lock-up agreements. In considering any request to release shares subject to a lock-up agreement, Goldman, Sachs & Co. will consider the facts and circumstances relating to a request at the time of that request.

If our existing common stockholders sell substantial amounts of common stock in the public market, or if the market perceives that these sales may occur, then the market price of our common stock may decline, including below the initial public offering price.

 

In addition, as soon as practicable after the completion of this offering, we intend to file a registration statement under the Securities Act covering           shares of common stock issuable upon exercise of outstanding options under our Nonqualified Stock Option Plan,           shares of common stock issuable upon exercise of outstanding options under our Directors’ Nonqualified Stock Option Plan,           shares of common stock issuable upon exercise of outstanding options under our 2002 Equity Incentive Plan and shares of common stock reserved for future issuance under our 2006 Equity Incentive Plan. The shares registered under such registration statement will be available for sale in the open market, subject to vesting restrictions with us, the contractual lock-up agreements described above and the contractual lock-up agreements and market stand-off provisions contained in the agreements pursuant to which these options were issued. If these additional shares are sold, or if it is perceived that they will be sold, in the public market, then the trading price of our common stock could decline. See “Shares Eligible for Future Sale.”

 

You will experience immediate and substantial dilution as a result of this offering and may experience additional dilution in the future.

 

We expect the initial public offering price of our common stock in this offering to be substantially higher than the net tangible book value per share of our outstanding common stock. Accordingly, investors purchasing shares of common stock in this offering will pay a price that substantially exceeds the value of our tangible assets after subtracting our liabilities. As a result, investors will:

 

 

You will experience additional dilution upon the exercise of options to purchase common stock under our equity incentive plans, if we issue restricted stock to our employees under these plans or if we otherwise issue additional shares of our common stock. See “Dilution.”

 

The provisions in our charter documents, as amended and restated, and under Delaware law could delay or discourage a takeover that stockholders may consider favorable.

 

Provisions in our amended and restated certificate of incorporation and amended and restated bylaws, to be effective upon completion of this offering, may have the effect of delaying or preventing a change of control or changes in our management. Some of these provisions include:

 

 

In addition, we are governed by the provisions of Section 203 of the Delaware General Corporation Law, which may prohibit certain business combinations with stockholders owning 15% or more of our outstanding voting stock. These and other provisions in our amended and restated certificate of incorporation, amended and restated bylaws and Delaware law could make it more difficult for stockholders or potential acquirers to obtain control of our board of directors or initiate actions that are opposed by the then-current board of directors, including to delay or impede a merger, tender offer, or proxy contest involving our company. Any delay or prevention of a change of control transaction or changes in our board of directors could cause the market price of our common stock to decline.

 

We will incur significant increased costs as a result of operating as a public company, and our management will be required to devote substantial time to new compliance initiatives.

 

As a public company, we will incur significant legal, accounting and other expenses that we did not incur as a private company. In addition, the Sarbanes-Oxley Act of 2002, as well as the related rules and regulations enacted by the Securities and Exchange Commission, or SEC, and the Nasdaq Global Market, have required changes in corporate governance practices of public companies. We expect these rules and regulations to increase our legal and financial compliance costs. In addition, we will incur additional costs associated with our public company reporting requirements. We also expect these rules and regulations to make it more difficult and more expensive for us to obtain director and officer liability insurance, and we may be required to accept reduced policy limits and coverage or incur substantially higher costs to obtain the same or similar coverage. As a result, it may be more difficult for us to attract and retain qualified persons to serve on our board of directors or as executive officers. We currently are evaluating and monitoring developments with respect to these rules, and we cannot predict or estimate the amount of additional costs we may incur or the timing of such costs.

 

We can provide no assurance regarding our conclusions as of April 30, 2008 with respect to the effectiveness of our internal control over financial reporting.

 

Beginning with our Annual Report on Form 10-K for the fiscal year ending April 30, 2008, pursuant to Section 404 of the Sarbanes-Oxley Act, our management will be required to deliver an annual report that assesses the effectiveness of our internal control over financial reporting, and we will be required to have our independent registered public accounting firm deliver an attestation report on management’s assessment. If our management or our independent registered public accounting firm were to conclude in their reports that our internal control over financial reporting was not effective, then investors could lose confidence in our reported financial information and the trading price of our stock could drop significantly.

 

We will be required to devote significant resources to complete the assessment and documentation of our internal control system and financial processes, including an assessment of the design of our information systems. We also may incur significant costs to remediate any control deficiencies we identify through these efforts. We cannot assure you that we will be able to complete the required management assessment by our Section 404 reporting deadline. An inability to complete and document this assessment would cause our auditors to conclude that our internal control over financial reporting was not effective. In addition, if a material weakness were identified with respect to our internal control over financial reporting, then neither we nor our auditors would be able to conclude that our internal control over financial reporting was effective. Ineffective internal control over financial reporting also could cause investors to lose confidence in our reported financial information, which could have a negative effect on the trading price of our common stock.

We may allocate the net proceeds from this offering in ways in which you and other stockholders may not agree or which may not yield a return.

 

We intend to use the net proceeds from this offering to increase our working capital, fund general corporate purposes, fund research and development, general marketing activities, general and administrative matters and finance opportunistic acquisitions and other capital expenditures.

 

Our management will, however, have broad discretion in the application of the net proceeds from this offering and you will not have the opportunity, as part of your investment decision, to assess whether the proceeds are being used appropriately. The net proceeds may be used for corporate purposes that do not necessarily improve our operating results or enhance the market value of our common stock. Until the net proceeds are used, they may be placed in investments that do not produce significant income or that lose value.

These statements are only predictions. We have based these forward-looking statements largely on our current expectations and projections about future events and financial trends that we believe may affect our business, financial condition and results of operations. We discuss many of the risks in greater detail under the heading “Risk Factors.” Also, these forward-looking statements represent our estimates and assumptions only as of the date of this prospectus. You should read this prospectus and the documents that we reference in this prospectus and have filed as exhibits to the registration statement, of which this prospectus is a part, completely and with the understanding that our actual future results may be materially different from what we expect. Except as required by law, we assume no obligation to update these forward-looking statements publicly, or to update the reasons actual results could differ materially from those anticipated in these forward-looking statements, even if new information becomes available in the future.

 

This prospectus also contains estimates and other statistical data made by independent parties and by us relating to market size and growth and other industry data. These data involve a number of assumptions and limitations, and you are cautioned not to give undue weight to such estimates. We have not independently verified the statistical and other industry data generated by independent parties and contained in this prospectus. In addition, projections, assumptions and estimates of our future performance and the future performance of the industries in which we operate are necessarily subject to a high degree of uncertainty and risk due to a variety of factors, including those described in “Prospectus Summary,” “Risk Factors,” “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” “Business” and elsewhere in this prospectus. These and other factors could cause results to differ materially from those expressed in the estimates made by the independent parties and by us.

 

We estimate that we will receive net proceeds of approximately $      million from the sale of the shares of common stock offered in this offering, based on an assumed initial public offering price of $      per share, which is the midpoint of the range set forth on the cover page of this prospectus, and after deducting the estimated underwriting discounts and commissions and estimated offering expenses payable by us. We will not receive any of the proceeds from the sale of shares of common stock by the selling stockholders.

 

The primary purpose of this offering is to fund working capital and other general corporate purposes, including to finance research and development of products, sales and marketing activities, opportunistic acquisitions and other capital expenditures. The amounts and timing of our actual expenditures may vary significantly from our expectations depending on numerous factors, including our results of operations, financial condition and capital requirements. Management has broad discretion to allocate the net proceeds of this offering among the identified uses described above. Pending their use, we intend to invest the net proceeds in short-term, interest-bearing, investment-grade securities.

 

If we were to price the offering at $      per share, the low end of the range on the cover of this prospectus, we estimate that we would receive net proceeds of $      million, assuming the total number of shares offered by us remains the same and after deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us. If we were to price the offering at $      per share, the high end of the range on the cover of this prospectus, then we estimate that we would receive net proceeds of $      million, assuming the total number of shares offered by us remains the same and after deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us.

 

We currently intend to retain all future earnings, if any, for use in the operation and expansion of our business and do not anticipate paying any cash dividends in the foreseeable future. Our debt agreements prohibit us from paying any dividends to our stockholders. Any future determination related to dividend policy will be made at the discretion of our board of directors and will depend upon, among other factors, our results of operations, financial condition, capital requirements, contractual restrictions and such other factors as our board of directors deems relevant.

 

The following table sets forth our capitalization as of October 28, 2006 on an actual basis and on an as adjusted basis, giving effect to:

 

 

You should read the following table in conjunction with our consolidated financial statements and related notes and the sections entitled “Selected Consolidated Financial Data” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” appearing elsewhere in this prospectus.

 

 

 

 

The number of shares of common stock to be outstanding after this offering is based on           shares outstanding as of October 28, 2006 and excludes the following:

 

 

If you invest in our common stock, your interest will be diluted to the extent the initial public offering price per share of our common stock in this offering exceeds the as adjusted net tangible book value per share of our common stock after completion of this offering. Net tangible book value per share is determined at any date by subtracting our total liabilities from the total book value of our tangible assets (total assets less intangible assets) and dividing the difference by the pro forma number of our shares of common stock deemed to be outstanding at that date. Dilution in net tangible book value per share represents the difference between the amount per share paid by purchasers of shares of common stock in this offering and the net tangible book value per share of common stock immediately after completion of this offering.

 

Our net tangible book value as of October 28, 2006, was approximately $40.8 million, or approximately $      per share of our common stock. Investors participating in this offering will incur immediate and substantial dilution.

 

After giving effect to the sale of           shares offered by us in this offering at an assumed initial public offering price of $      per share, the midpoint of the range set forth on the cover page of this prospectus, and after deducting estimated underwriting discounts and commissions and our estimated offering expenses, our as adjusted net tangible book value as of October 28, 2006 would have been approximately $      million, or approximately $      per share of common stock. This represents an immediate increase in as adjusted net tangible book value of $      per share to existing stockholders and an immediate dilution in as adjusted net tangible book value of $      per share to new investors. The following table illustrates this per share dilution:

 

 

The following table summarizes, as of October 28, 2006, as adjusted to give effect to this offering, the differences between the number of shares of common stock purchased from us, the total cash consideration paid, and the average price per share paid by our existing stockholders and by our new investors purchasing stock in this offering. The calculation below is based on an assumed initial public offering price of $      per share, the midpoint of the range set forth on the cover page of this prospectus, before deducting the estimated underwriting discounts and commissions and estimated offering expenses payable by us:

 

 

If the underwriters exercise their over-allotment option in full, our existing stockholders would own  % and our new investors would own  % of the total number of shares of our common stock outstanding after this offering.

The above discussion and tables assume no exercise of options outstanding as of October 28, 2006. As of October 28, 2006, we had outstanding options to purchase a total of           shares of common stock at a weighted average exercise price of $      per share. To the extent any of these options are exercised, there will be further dilution to new investors.

 

Sales of common stock by the selling stockholders in the offering will reduce the number of shares of common stock held by existing stockholders to          , or approximately  % of the total shares of common stock outstanding after the offering, and will increase the number of shares held by new public investors to          , or approximately  % of the total shares of common stock outstanding after the offering.

 

A $1.00 decrease in the assumed offering price would decrease our net tangible book value after this offering by $      million and dilution in net tangible book value per share to new investors by $     , assuming the total number of shares offered by us remains the same and after deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us. A $1.00 decrease in the assumed offering price would decrease each of total consideration paid by new investors in the offering and total consideration paid by all stockholders by $      million, assuming the total number of shares offered by us remains the same and before deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us.

 

A $1.00 increase in the assumed offering price would increase our net tangible book value after this offering by $      million and dilution in net tangible book value per share to new investors by $     , assuming the total number of shares offered by us remains the same and after deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us. A $1.00 increase in the assumed offering price would increase each of total consideration paid by new investors in the offering and total consideration paid by all stockholders by $      million, assuming the total number of shares offered by us remains the same and before deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us.

Overview

 

We design, develop, produce and support a technologically-advanced portfolio of small unmanned aircraft systems that we supply primarily to organizations within the U.S. Department of Defense, 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. Customers for our small unmanned aircraft systems, or UAS, include the U.S. Army, U.S. Marine Corps and the U.S. Special Operations Command, or SOCOM. Our PosiCharge customers, including Ford Motor Company, SYSCO Corporation, Southwest Airlines and IKEA, utilize our fast charge systems in their factories, distribution centers, cold storage facilities and airport ground support operations. The success we have achieved with our current products stems from 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 small UAS are well positioned to support the transformational strategy of the U.S. Department of Defense, or DoD, the purpose of which is to convert the military into a smaller, more agile force that operates through a network of observation, communication and precision targeting technologies, and its efforts to prosecute the global war on terror, which have increased the need for real-time, visual information in new operational environments. Our small UAS, including Raven, Dragon Eye, Swift, Wasp and Puma, are designed to provide valuable intelligence, surveillance and reconnaissance, or ISR, directly to the small tactical unit, or individual “warfighter” level, thereby increasing flexibility in mission planning and execution. We also provide training by our highly-skilled instructors, who typically have extensive military experience, and continuous refurbishment and repair services for our products.

 

Our PosiCharge products and 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. PosiCharge utilizes our proprietary technology in energy and battery management to recharge electric industrial vehicle batteries rapidly during regularly scheduled breaks or other times the vehicle is not in service, eliminating the costly and time-consuming process of removing and replacing the battery. PosiCharge is able to recharge a typical electric industrial vehicle battery up to six times faster than a conventional charger. Utilizing its current, voltage and temperature management capabilities, PosiCharge eliminates the need to cool batteries during and after normal charging, which can take up to eight hours, thereby allowing the batteries to remain in the vehicles during the charging process. These capabilities can also serve to enhance battery performance and lifespan. As of October 28, 2006, our PosiCharge fast charge systems serviced over 5,000 electric industrial vehicles. We estimate that approximately 1.0 million electric industrial vehicles currently operate in North America, including over 100,000 new vehicles that we estimate were shipped in 2005.

 

  Revenue

 

We generate our revenue primarily from the sale and support of our small UAS and PosiCharge solutions. Support for our small UAS customers includes training, customer support and repair and

replacement work, which we refer to collectively as our logistics operation. We derive most of our small UAS revenue from fixed-price and cost-plus-fee contracts with the U.S. government and most of our PosiCharge revenue from sales and service to commercial customers. We also generate revenue from our Energy Technology Center through the provision of contract development and engineering services, the sale of our power processing systems and license fees. For the fiscal years ended April 30, 2005 and 2006 and for the six months ended October 28, 2006, the UAS segment accounted for 78%, 80% and 82% of our revenue, respectively; the PosiCharge segment accounted for 15%, 14% and 12% of our revenue, respectively; and the Energy Technology Center segment accounted for 7%, 6% and 6% of our revenue, respectively.

 

  Cost of Sales

 

Cost of sales consists of direct costs and allocated indirect costs. Direct costs include labor, materials, travel, subcontracts and other costs directly related to the execution of a specific contract. Indirect costs include overhead expenses, fringe benefits and other costs that are not directly related to the execution of a specific contract. For the fiscal years ended April 30, 2005 and 2006 and for the six months ended October 28, 2006, cost of sales were 56%, 59% and 61% of our revenue, respectively.

 

Gross Margin

 

Gross margin is equal to revenue minus cost of sales. We use gross margin as a financial metric to help us understand trends in our direct costs and allocated indirect costs when compared to the revenue we generate. For the fiscal years ended April 30, 2005 and 2006 and for the six months ended October 28, 2006, gross margin was 44%, 41% and 39% of our revenue, respectively.

 

  Research and Development Expense

 

Research and development, or R&D, is an integral part of our business model. We conduct significant internally funded research and development and anticipate that research and development expense will continue to increase in absolute dollars for the foreseeable future. Our UAS research and development activities focus specifically on creating capabilities that support our existing small UAS product portfolio as well as new UAS platforms. These activities are funded both externally by customers and internally. In addition, we currently have a number of potential products in various stages of development and commercialization within our research and development program. For the fiscal years ended April 30, 2005 and 2006 and for the six months ended October 28, 2006, R&D expense accounted for 9%, 12% and 9% of our revenue, respectively.

 

  Backlog

 

Our backlog is comprised of funded and unfunded amounts provided in our contracts. 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. We define unfunded backlog as the total remaining potential order amounts under indefinite delivery indefinite quantity, or IDIQ, contracts. IDIQ contracts do not obligate the U.S. government to purchase goods or services. 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 funded backlog was $70.4 million and $79.7 million as of April 30, 2005 and 2006, respectively. Our unfunded backlog was $262.8 million and $475.5 million as of April 30, 2005 and 2006, respectively. As of October 28, 2006, our funded backlog was $69.5 million and unfunded backlog was $491.5 million.

Selling, General and Administrative

 

Our selling, general and administrative expenses, or SG&A, include salaries and other expenses related to selling, marketing and proposal activities, and other administrative costs. In addition, expense associated with our supplemental executive retirement plan is included in SG&A. SG&A is an important financial metric that we analyze to help us evaluate the contribution of our selling, marketing and proposal activities to revenue generation. For the fiscal years ended April 30, 2005 and 2006 and for the six months ended October 28, 2006, SG&A was 16%, 18% and 17% of our revenue, respectively.

 

Other Income and Expenses

 

Other income and expenses include interest income, interest expense, and the recovery of a previously written-off note receivable.

 

Income Tax Expense

 

Beginning in fiscal 2005, our effective tax rates were substantially lower than the statutory rates primarily due to research and development tax credits. The federal research and development tax credit expired in December 2005, but is expected to be reinstated for two years beginning retroactively on January 1, 2006, which will result in a decrease in our expected annual tax rate.

 

Critical Accounting Policies and Estimates

 

Management’s Discussion and Analysis of Financial Condition and Results of Operations discusses our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. When we prepare these consolidated financial statements, we are required to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Some of our accounting policies require that we make subjective judgments, including estimates that involve matters that are inherently uncertain. Our most critical estimates include those related to revenue recognition, inventories and reserves for excess and obsolescence, our supplemental executive retirement plan, self-insured liabilities, accounting for stock-based awards, and income taxes. We base our estimates and judgments on historical experience and on various other factors that we believe to be reasonable under the circumstances, the results of which form the basis for our judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Our actual results may differ from these estimates under different assumptions or conditions.

 

We believe the following critical accounting estimates affect our more significant judgments and estimates used in preparing our consolidated financial statements. See Note 1 of the Notes to Consolidated Financial Statements for our Summary of Significant Accounting Policies. There have been no material changes made to the critical accounting estimates during the periods presented in the consolidated financial statements.

 

Revenue Recognition

 

Significant management judgments and estimates must be made and used in connection with the recognition of revenue in any accounting period. Material differences in the amount of revenue in any given period may result if these judgments or estimates prove to be incorrect or if management’s estimates change on the basis of development of the business or market conditions.

 

The substantial majority of our revenue is generated pursuant to written contractual arrangements to design, develop, manufacture and/or modify complex products, and to provide related engineering, technical and other services according to customer specifications. These contracts may be fixed-price or cost-reimbursable. We consider all contracts for treatment in accordance with Financial Accounting Standards Board Emerging Issues Task Force No. 00-21, “Revenue

Arrangements with Multiple Deliverables” (“EITF 00-21”). EITF 00-21 provides for deferral to higher authoritative guidance, including American Institute of Certified Public Accountants Statement of Position 81-1, “Accounting for Performance of Construction-Type and Certain Production-Type Contracts” (“SOP 81-1”), under which the majority of our contracts are properly accounted for. Contracts which provide for multiple deliverables to which SOP 81-1 does not apply are accounted for in accordance with the provisions of EITF No. 00-21.

 

Revenue from product sales not under contractual arrangement is recognized at the time title and the risk and rewards of ownership pass, which typically occurs when the products are shipped and collection is reasonably assured.

 

Revenue and profits on fixed-price contracts are recognized using percentage-of-completion methods of accounting. Revenue and profits on fixed-price production contracts, whose units are produced and delivered in a continuous or sequential process, are recorded as units are delivered based on their selling prices, or the units-of-delivery method. Revenue and profits on other fixed-price contracts with significant engineering as well as production requirements are recorded based on the ratio of total actual incurred costs to date to the total estimated costs for each contract, or the cost-to-cost method. Under percentage-of-completion methods of accounting, a single estimated total profit margin is used to recognize profit for each contract over its entire period of performance, which can exceed one year. Accounting for revenue and profits on a fixed-price contract requires the preparation of estimates of (1) the total contract revenue, (2) the total costs at completion, which is equal to the sum of the actual incurred costs to date on the contract and the estimated costs to complete the contract’s statement of work and (3) the measurement of progress towards completion. The estimated profit or loss at completion on a contract is equal to the difference between the total estimated contract revenue and the total estimated cost at completion. Under the units-of-delivery method, sales on a fixed-price type contract are recorded as the units are delivered during the period based on their contractual selling prices. Under the cost-to-cost method, sales on a fixed-price type contract are recorded at amounts equal to the ratio of actual cumulative costs incurred divided by total estimated costs at completion, multiplied by (A) the total estimated contract revenue, less (B) the cumulative sales recognized in prior periods. The profit recorded on a contract in any period using either the units-of-delivery method or cost-to-cost method is equal to (X) the current estimated total profit margin multiplied by the cumulative sales recognized, less (Y) the amount of cumulative profit previously recorded for the contract. In the case of a contract for which the total estimated costs exceed the total estimated revenue, a loss arises, and a provision for the entire loss is recorded in the period that it becomes evident. The unrecoverable costs on a loss contract that are expected to be incurred in future periods are recorded in the program cost.

 

Revenue and profits on cost-reimbursable type contracts are recognized as costs are incurred on the contract, at an amount equal to the costs plus the estimated profit on those costs. The estimated profit on a cost-reimbursable contract is generally fixed or variable based on the contractual fee arrangement.

 

We review cost performance and estimates to complete at least quarterly and in many cases more frequently. Adjustments to original estimates for a contract’s revenue, estimated costs at completion and estimated profit or loss are often required as work progresses under a contract, as experience is gained and as more information is obtained, even though the scope of work required under the contract may not change, or if contract modifications occur. The impact of revisions in profit estimates for all types of contracts are recognized on a cumulative catch-up basis in the period in which the revisions are made. Amounts representing contract change orders or claims are included in revenue only when they can be reliably estimated and their realization is probable. Incentives or penalties and awards applicable to performance on contracts are considered in estimating revenue and profit rates, and are recorded when there is sufficient information to assess anticipated contract performance. Revenue on arrangements that are not within the scope of SOP 81-1 are recognized in accordance with the SEC Staff Accounting Bulletin No. 104, “Revenue Recognition in Financial Statements.”

Inventories and Reserve for Excess and Obsolescence

 

Our policy for valuation of inventory, including the determination of obsolete or excess inventory, requires us to perform a detailed assessment of inventory at each balance sheet date, which includes a review of, among other factors, an estimate of future demand for products within specific time horizons, valuation of existing inventory, as well as product lifecycle and product development plans. Inventory reserves are also provided to cover risks arising from slow-moving items. 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 on assumptions about future demand and market conditions. We may be required to record additional inventory write-downs if actual market conditions are less favorable than those projected by our management. Our inventory reserve balance was $0.6 million, $1.1 million and $0.8 million at April 30, 2004, 2005, and 2006, respectively. The increase in the inventory reserve of $0.5 million to $1.1 million at April 30, 2005 from $0.6 million at April 30, 2004 was primarily due to additional inventory reserves for an earlier generation small UAS product line.

 

Supplemental Executive Retirement Plan Obligation

 

We maintain a supplemental executive retirement plan, which is a non-qualified defined benefit plan for Dr. MacCready, our Founder and Chairman of our board of directors. The plan is non-contributory and non-funded. Pension expense is determined using various actuarial cost methods to estimate the total benefits ultimately payable to the plan beneficiary, and this amount is accrued as a liability on our balance sheet. We review the actuarial assumptions used to calculate pension costs annually. Based upon the terms of this plan, the plan and all obligations under the plan will terminate automatically upon completion of this offering without any payment or promise of future payment to Dr. MacCready, which will result in a reversal of the related accrued expense of approximately $2.2 million in the period in which the offering is completed.

 

Self-Insured Liability

 

We are self-insured for employee medical claims, subject to individual and aggregate stop-loss policies. We estimate a liability for claims filed and incurred but not reported claims based upon recent claims experience and an analysis of the average period of time between the occurrence of a claim and the time it is reported to and paid by us. We perform an annual evaluation of this policy and have determined that for all prior years during which this policy has been in effect there have been cost advantages to this policy, as compared to obtaining commercially available employee medical insurance. However, actual results may differ materially from those estimated and could have a material impact on our consolidated financial statements.

 

Accounting for Stock-Based Awards

 

Historically, we applied Accounting Principles Board No. 25, “Accounting for Stock Issued to Employees,” and related interpretations, or Opinion 25, in accounting for our stock-based compensation plans. We granted options with exercise prices at or above the estimated fair value of our common stock. No compensation expense was recorded as the exercise price equals or exceeds the fair value of the underlying stock on the grant date.

 

In December 2004, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards No. 123 (revised 2004), “Share-Based Payment,” or SFAS 123R. SFAS 123R eliminates the alternative of applying the intrinsic value measurement provisions of Opinion 25 to stock compensation awards issued to employees. Instead, SFAS 123R requires companies to measure the cost of employee services received in exchange for an award of equity instruments based on the grant-date fair value of the award. That cost must be recognized over the period during which an employee is required to provide services in exchange for the award, known as the requisite service period, which is usually the vesting period. We adopted SFAS 123R effective May 1, 2006. Because

we historically used the minimum value method of measuring stock options, implementation of SFAS 123R applies prospectively to new awards after adoption. No expense is recognized for options granted prior to adoption. We awarded options representing        shares to employees during the six months ended October 28, 2006. Compensation expense of approximately $8,000, which represents the portion of those awards vesting, is included in our income statement for that period.

 

We estimate the fair value of stock options granted after adoption of SFAS 123R at the grant date, using a Black-Scholes option pricing model.

 

Given the absence of an active market for our common stock, our board of directors is required to estimate the fair value of our common stock. Our board of directors considered numerous objective and subjective factors in determining the value of our common stock at each option grant date, including the following factors: (1) recent transactions in our common stock; (2) contemporaneous valuations; (3) the fact that the option grants involved illiquid securities in a private company; (4) our stage of development and revenue growth; and (5) the likelihood of achieving a liquidity event for the shares of common stock underlying the options, such as an initial public offering or sale of our company, given prevailing market conditions. We did not obtain a contemporaneous valuation by an independent valuation specialist in connection with grants of options to acquire 63,000 shares of our common stock at an exercise price of $15 per share on October 20, 2005. Instead, our board of directors determined the fair market of our common stock at the time of such grant based upon contemporaneous substantial sales of our common stock at a price of $15 per share by one of our independent directors, Murray Gell-Mann, to another of our independent directors, Arnold L. Fishman, and to the Whiting Family Partnership, a family limited partnership of which Timothy E. Conver, our Chief Executive Officer, is a limited partner.

 

Assuming an initial offering price of our common stock of $      per share, which is the midpoint of the range set forth on the cover page of this prospectus, the public offering price of our common stock will exceed the exercise price of options issued by us in September 2006 by $      per share. We believe that this increase in the fair value of our common stock was primarily attributable to the following developments during the period:

 

 

Although it is reasonable to expect that the completion of this offering may further increase the value of our common stock underlying our outstanding options as a result of their increased marketability, the amount of such additional value cannot be measured with precision or certainty.

Income Taxes

 

We are required to estimate our income taxes, which includes estimating our current income taxes as well as measuring the temporary differences resulting from different treatment of items for tax and accounting purposes. We currently have significant deferred assets, which are subject to periodic recoverability assessments. Realizing our deferred tax assets principally depends on our achieving projected future taxable income. We may change our judgments regarding future profitability due to future market conditions and other factors, which may result in recording a valuation allowance against those deferred tax assets. Beginning in fiscal 2005, our effective tax rates were substantially lower than the statutory rates primarily due to research and development tax credits. The federal research and development tax credit expired in December 2005, but is expected to be reinstated for two years beginning retroactively on January 1, 2006, which will result in a decrease in our expected annual tax rate.

 

Fiscal Periods

 

Our fiscal year ends on April 30 and our fiscal quarters end on the last Saturday of July, October and January.

 

Results of Operations

 

The following table sets forth certain historical consolidated income statement data expressed in dollars (in thousands) and as a percentage of revenue for the periods indicated. Certain amounts may not calculate due to rounding.

 

 

Our operating segments are UAS, PosiCharge fast charge systems and our Energy Technology Center. The accounting policies for each of these segments are the same. In addition, a significant portion of our research and development, selling, general and administrative, and general overhead resources are shared across our segments.

The following table sets forth our revenue and gross margin generated by each operating segment for the periods indicated:

 

 

Six Months Ended October 28, 2006 Compared to Six Months Ended October 29, 2005

 

Revenue.  Revenue for the six months ended October 28, 2006 was $76.7 million, as compared to $73.3 million for the six months ended October 29, 2005, representing an increase of $3.4 million, or 5%. UAS revenue increased $5.0 million to $62.9 million for the six months ended October 28, 2006, largely due to the continued growth of our logistics operation. Revenue from our logistics operation increased $7.1 million, while UAS product sales decreased $4.0 million. The decrease in UAS product sales was largely due to product shipments being deferred into the latter part of this fiscal year pending customer testing and evaluation, which has been completed. PosiCharge fast charge systems revenue decreased by $2.2 million to $9.5 million for the six months ended October 28, 2006, primarily due to lower installations of PosiCharge with our automotive customers. Energy Technology Center revenue increased by $0.7 million to $4.4 million in the six months ended October 28, 2006, primarily due to higher sales of power processing test equipment.

 

Cost of Sales.  Cost of sales for the six months ended October 28, 2006 was $47.0 million, as compared to $44.5 million for the six months ended October 29, 2005, representing an increase of $2.5 million, or 5%. The increase in cost of sales was caused primarily by higher UAS cost of sales of $3.6 million and Energy Technology Center cost of sales of $0.2 million offset by lower PosiCharge fast charge systems cost of sales of $1.3 million.

 

Gross Margin.  Gross margin for the six months ended October 28, 2006 was $29.8 million, as compared to $28.8 million for the six months ended October 29, 2005, representing an increase of $1.0 million, or 3%. UAS gross margin increased $1.4 million to $23.8 million for the six months ended October 28, 2006. As a percentage of revenue, gross margin for UAS decreased slightly from 39% to 38%. PosiCharge fast charge systems gross margin decreased $0.9 million to $3.8 million for the six months ended October 28, 2006, due to lower sales volume. As a percentage of revenue, PosiCharge fast charge systems gross margin was 40% for the six months ended October 28, 2006 and October 29, 2005. Energy Technology Center gross margin increased $0.4 million to $2.2 million for the six months ended October 28, 2006, primarily due to higher sales of power processing test equipment. As a percentage of revenue, Energy Technology Center gross margin increased from 47% to 50% for the six months ended October 28, 2006, primarily due to the higher equipment sales relative to customer-funded research and development work.

 

Research and Development.  R&D expense for the six months ended October 28, 2006 was $7.0 million (or 9% of revenue), which is in line with R&D expense of $7.1 million (or 10% of revenue) for the six months ended October 29, 2005.

Selling, General and Administrative.  SG&A expense for the six months ended October 28, 2006 was $12.9 million (or 17% of revenue), compared to SG&A expense of $11.3 million (or 15% of revenue) in the six months ended October 29, 2005. The increase in SG&A expense of $1.6 million was caused primarily by the added administrative and marketing infrastructure necessary as we continue to grow our business.

 

Income Tax Expense.  Our effective income tax rate was 38.7% for the six months ended October 28, 2006, as compared to 30.0% for the six months ended October 29, 2005. This increase was due to the expiration of the federal research and development tax credit on December 31, 2005. This tax credit is expected to be reinstated for two years beginning retroactively on January 1, 2006. Consequently, we will make an adjustment to our effective tax rate in the fiscal period during which the tax credit is reinstated, the quarter ended January 27, 2007.

 

Fiscal Year Ended April 30, 2006 Compared to Fiscal Year Ended April 30, 2005

 

Revenue.  Revenue for the fiscal year ended April 30, 2006 was $139.4 million, as compared to $105.2 million for the fiscal year ended April 30, 2005, representing an increase of $34.2 million, or 33%. UAS revenue increased $28.9 million to $111.1 million for the fiscal year ended April 30, 2006, largely due to the continued growth of our logistics operations, which were launched in the fiscal year ended April 30, 2005 and accounted for $20.1 million of the increase in UAS revenue. The remaining increase in UAS revenue of $8.8 million was due to an increase in product sales. PosiCharge fast charge systems revenue increased by $4.3 million to $19.9 million for the fiscal year ended April 30, 2006 primarily due to acceptance of PosiCharge into multiple facilities operated by one of our existing customers. Energy Technology Center revenue increased by $1.1 million to $8.3 million in the fiscal year ended April 30, 2006, primarily due to an increase in sales of power processing test equipment.

 

Cost of Sales.  Cost of sales for the fiscal year ended April 30, 2006 was $82.6 million, as compared to $58.5 million for the fiscal year ended April 30, 2005, representing an increase of $24.1 million, or 41%. The increase in cost of sales was caused by higher UAS cost of sales of $21.5 million, higher PosiCharge fast charge systems cost of sales of $2.1 million, and higher Energy Technology Center cost of sales of $0.4 million. The increase in UAS cost of sales was largely due to a full year of our logistics activities. The increase in PosiCharge fast charge systems cost of sales was primarily due to the continued adoption of our fast charge systems.

 

Gross Margin.  Gross margin for the fiscal year ended April 30, 2006 was $56.8 million, as compared to $46.6 million for the fiscal year ended April 30, 2005, representing an increase of $10.2 million, or 22%. UAS gross margin increased $7.3 million to $44.6 million for the fiscal year ended April 30, 2006. As a percentage of revenue, gross margin for UAS decreased from 45% to 40%, largely due to a reduction in pricing on UAS production orders in fiscal year 2006 and an increase in cost-plus-fee contracts relative to fixed-price contracts, the former of which tend to have lower gross margins, as described more fully in “Government Contracting Process.” The lower pricing also reflected the pass-through of manufacturing cost efficiencies to our customers. PosiCharge fast charge systems gross margin increased $2.2 million to $8.1 million for the fiscal year ended April 30, 2006, due to the increase in sales volume. As a percentage of revenue, PosiCharge fast charge systems gross margin increased from 37% to 40% for the fiscal year ended April 30, 2006, due to the achievement of direct and indirect cost efficiencies coincident with higher sales volume. Energy Technology Center gross margin increased $0.6 million to $4.1 million for the fiscal year ended April 30, 2006, primarily due to increased sales of power processing test equipment. As a percentage of revenue, Energy Technology Center gross margin increased from 49% to 50% for the fiscal year ended April 30, 2006, primarily due to the higher sales mix of equipment sales compared to customer-funded research and development work.

 

Research and Development.  R&D expense for the fiscal year ended April 30, 2006 was $16.1 million (or 12% of revenue), compared to R&D expense of $9.8 million (or 9% of revenue) for

the fiscal year ended April 30, 2005. The increase in R&D expense reflected our investment in improvement and expansion of existing product lines and development of new product opportunities.

 

Selling, General and Administrative.  SG&A expense for the fiscal year ended April 30, 2006 was $24.8 million (or 18% of revenue), compared to SG&A expense of $16.7 million (or 16% of revenue) in the fiscal year ended April 30, 2005. The increase in SG&A expense of $8.1 million was caused primarily by the added administrative and marketing infrastructure necessary to support the growth in our business volume and to enhance the documentation of our internal controls. Further, the increase in SG&A expense partially reflects the lag in SG&A infrastructure growth relative to the revenue growth we experienced in the fiscal year ended April 30, 2005. As a percentage of revenue, SG&A expense increased to 18% in the fiscal year ended April 30, 2006, primarily due to the establishment of a supplemental executive retirement plan for Dr. MacCready, our Founder and Chairman of our board of directors. The expense associated with this plan was $2.2 million (or 2% of revenue) in 2006.

 

Income Tax Expense.  Our effective income tax rate was 30.2% for the fiscal year ended April 30, 2006, as compared to 27.2% for the fiscal year ended April 30, 2005. The increase was due to a reduction in the federal research and development tax credit computed based on the expiration of the tax credit on December 31, 2005. The tax credit is expected to be reinstated for two years beginning retroactively on January 1, 2006. Consequently, we will make an adjustment to our effective tax rate in the fiscal period during which the tax credit is reinstated, the quarter ended January 27, 2007.

 

Fiscal Year Ended April 30, 2005 Compared to Fiscal Year Ended April 30, 2004

 

Revenue.  Revenue for the fiscal year ended April 30, 2005 was $105.2 million, as compared to $47.7 million for the fiscal year ended April 30, 2004, representing an increase of $57.5 million, or 121%. UAS sales increased $51.9 million to $82.2 million for the fiscal year ended April 30, 2005, due to the high volume of UAS deliveries achieved during the first full year of full-rate UAS production. PosiCharge fast charge systems sales increased $6.5 million to $15.6 million for the fiscal year ended April 30, 2005 due to the continued adoption of these systems, particularly with one existing customer that implemented PosiCharge in many of its North American plants. The decrease in Energy Technology Center sales of $0.9 million was largely due to a decrease in customer-funded research and development.

 

Cost of Sales.  Cost of sales for the fiscal year ended April 30, 2005 was $58.5 million, as compared to $33.1 million for the fiscal year ended April 30, 2004, representing an increase of $25.4 million, or 77%. The increase in cost of sales was driven by higher UAS cost of sales of $24.8 million and higher PosiCharge fast charge systems cost of sales of $4.2 million, partially offset by a decline in Energy Technology Center cost of sales of $3.6 million. The increase in UAS cost of sales was largely due to the high volume of UAS deliveries achieved during the first full year of full-rate UAS production activities. The increase in PosiCharge fast charge systems cost of sales was primarily due to increased adoption and implementation of fast charge systems. The decrease in Energy Technology Center cost of sales was primarily due to lower overall sales and a change in the mix of business toward lower cost power processing systems and write-down of inventory that occurred in 2004 and was not present in 2005.

 

Gross Margin.  Gross margin for the fiscal year ended April 30, 2005 was $46.6 million, as compared to $14.6 million for the fiscal year ended April 30, 2004, representing an increase of $32.0 million, or 220%. UAS gross margin increased $27.1 million to $37.2 million for the fiscal year ended April 30, 2005. As a percentage of revenue, UAS gross margin increased from 33% to 45% for the fiscal year ended April 30, 2005, primarily due to efficiencies achieved during the first full year of full-rate UAS production. PosiCharge fast charge systems gross margin increased $2.3 million to $5.8 million as of April 30, 2005. As a percentage of revenue, PosiCharge fast charge systems gross margin decreased from 39% to 37% for the fiscal year ended April 30, 2005, primarily due to volume

pricing incentives. Energy Technology Center gross margin increased $2.7 million to $3.5 million for the fiscal year ended April 30, 2005. As a percentage of revenue, Energy Technology Center gross margin increased from 11% to 49% for the fiscal year ended April 30, 2005, primarily due to the change in the mix of business toward lower cost power processing systems and write-down of inventory that occurred in 2004 and was not present in 2005.

 

Research and Development.  R&D expense for the fiscal year ended April 30, 2005 was $9.8 million (or 9% of revenue), compared to R&D expense of $1.7 million (or 4% of revenue) for the fiscal year ended April 30, 2004. The increase in R&D expense reflected our investment in improvement and expansion of existing product lines and development of new product opportunities.

 

Selling, General and Administrative.  SG&A expense for the fiscal year ended April 30, 2005 was $16.7 million (or 16% of revenue), compared to SG&A expense of $9.7 million (or 20% of revenue) for the fiscal year ended April 30, 2004. The year-over-year increase in SG&A expense of $7.0 million was caused by adding infrastructure necessary to support our year-over-year sales growth. As a percentage of revenue, our infrastructure costs lagged behind the increase in revenue in 2005.

 

Income Tax Expense.  Our effective income tax rate was 27.2% for the fiscal year ended April 30, 2005, as compared to 28.3% for the fiscal year ended April 30, 2004. The decrease was due to an increase in research and development tax credits, offset in part by a reduction of an amount in excess of the tax liability for 2004.

 

Liquidity and Capital Resources

 

We currently have no material cash commitments, except for normal recurring trade payables, accrued expenses and ongoing research and development costs, all of which we anticipate funding through our existing working capital, funds provided by operating activities and our working capital line of credit. The majority of our purchase obligations are pursuant to funded contractual arrangements with our customers. In addition, we do not currently anticipate significant investment in property, plant and equipment, and we believe that our existing cash, cash equivalents, cash provided by operating activities, funds available through our working capital line of credit and other financing sources and the net proceeds from this offering will be sufficient to meet our anticipated working capital, capital expenditure and debt service requirements, if any, during the next twelve months. There can be no assurance, however, that our business will continue to generate cash flow at current levels. If we are unable to generate sufficient cash flow from operations, then we may be required to sell assets, reduce capital expenditures or obtain additional financing.

 

Our primary liquidity needs are for financing working capital, investing in capital expenditures, supporting product development efforts, introducing new products and enhancing existing products, and marketing acceptance and adoption of our products and services. Our future capital requirements, to a certain extent, are also subject to general conditions in or affecting the defense industry and are subject to general economic, political, financial, competitive, legislative and regulatory factors that are beyond our control. Moreover, to the extent that existing cash, cash equivalents, cash from operations, cash from short-term borrowing and the net proceeds from this offering are insufficient to fund our future activities, we may need to raise additional funds through public or private equity or debt financing. Although we are currently not a party to any agreement or letter of intent with respect to potential investment in, or acquisitions of, businesses, services or technologies, we may enter into these types of arrangements in the future, which could also require us to seek additional equity or debt financing.

 

Our working capital requirements vary by contract type. On cost-plus-fee programs, we typically bill our incurred costs and fees monthly as work progresses, and therefore working capital investment is minimal. On fixed-price contracts, we typically are paid as we deliver products, and working capital is needed to fund labor and expenses incurred during the lead time from contract award until contract deliveries begin.

Cash Flows

 

The following table provides our cash flow data for each of the years in the three-year period ended April 30, 2006 and for each of the six months ended October 29, 2005 and October 28, 2006:

 

 

Cash Provided by Operating Activities.  Net cash used in operating activities for the six months ended October 28, 2006 increased by $10.1 million to $2.3 million, compared to net cash provided by operating activities of $7.8 million for the six months ended October 29, 2005. This increase in net cash used in operating activities was primarily due to continued sales growth that resulted in increased working capital needs of $8.3 million.

 

Net cash provided by operating activities for the fiscal year ended April 30, 2006 increased by $4.8 million to $13.4 million, compared to $8.6 million for the fiscal year ended April 30, 2005. The increase in net cash provided by operating activities was primarily due to improved working capital of $9.2 million, an accrual for long-term retirement costs of $2.2 million and increased depreciation and amortization of $0.9 million, partially offset by lower net income of $3.3 million. Accounts receivable was higher at April 30, 2006 than at April 30, 2005 primarily due to overall higher sales volume for the fiscal year ended April 30, 2006. Inventories were roughly the same at April 30, 2006 and at April 30, 2005.

 

Net cash provided by operating activities for the fiscal year ended April 30, 2005 increased $7.0 million to $8.6 million, compared to $1.6 million for the fiscal year ended April 30, 2004. The increase in net cash provided by operating activities was primarily due to higher net income of $12.3 million and higher depreciation and amortization of $0.3 million, partially offset by higher working capital needs of $4.8 million. Accounts receivable and inventories were higher at April 30, 2005 than at April 30, 2004 primarily due to overall higher sales volume for the fiscal year ended April 30, 2005.

 

Our cash flows from operating activities are dependent on the timing of receipts from various government payment offices and commercial customers and, as a result, may differ from period to period. Such variations from period to period in cash flows from operating activities could be significant.

 

Cash Used in Investing Activities.  Net cash used in investing activities was $1.3 million for the six months ended October 28, 2006, compared to $1.8 million for the six months ended October 29, 2005. During the six months ended October 28, 2006 and October 29, 2005, we used cash to purchase property and equipment totaling $1.3 million and $1.8 million, respectively.

 

Net cash used in investing activities increased $0.7 million to $4.2 million for the fiscal year ended April 30, 2006, compared to $3.5 million for the fiscal year ended April 30, 2005. The increase in net cash used in investing activities was primarily due to increased purchases of property and equipment of $0.6 million, primarily for the expansion of our UAS business.

 

Net cash used in investing activities increased $2.2 million to $3.5 million for the fiscal year ended April 30, 2005, compared to $1.3 million for the fiscal year ended April 30, 2004. The increase

in net cash used in investing activities was primarily due to increased purchases of property and equipment of $2.1 million, primarily related to capital costs associated with the implementation of our new ERP system.

 

Cash Provided by Financing Activities.  Net cash provided by financing activities increased $1.8 million to $1.3 million for the six months ended October 28, 2006, compared to net cash used by financing activities of $0.5 million for the six months ended October 29, 2005. During the six months ended October 28, 2006, we collected $0.2 million from the exercise of stock options. Long-term debt payments, net of borrowings, during the six months ended October 28, 2006 decreased by $0.5 million, compared to the six months ended October 29, 2005. In addition, we fulfilled the delivery terms outlined in a standby letter of credit that allowed us to release $1.1 million of restricted cash.

 

Net cash used in financing activities increased $5.4 million to $3.8 million for the fiscal year ended April 30, 2006, compared to net cash provided by financing activities of $1.6 million for the fiscal year ended April 30, 2005. The increase in net cash used in financing activities was primarily due to paying down our long term debt of $2.0 million and the transfer of $1.5 million to restricted cash to secure standby letters of credit established for the benefit of our customers, partially offset by no debt borrowings and a decrease of $0.6 million received from stock option exercises. At April 30, 2006, as a result of our strategy to pay down debt, we had no long term debt.

 

Net cash provided by financing activities increased $0.5 million to $1.6 million for the fiscal year ended April 30, 2005, compared to $1.1 million for the fiscal year ended April 30, 2004. The increase in net cash provided by financing activities was primarily due to higher collections of $0.7 million associated with stock option exercises, partially offset by common stock repurchases of $0.1 million. At April 30, 2005, we had $2.5 million in long term debt, incurred to finance the expansion of our UAS business.

 

Line of Credit and Term Loan Facilities

 

We have a revolving line of credit with a bank, under which we may borrow up to $16.5 million, and a term loan facility, under which we may borrow up to $5.0 million. Borrowings bear interest at the bank’s prime commercial lending rate, which was 7.75% and 8.25% as of April 30, 2006 and October 28, 2006, respectively. The line of credit is secured by substantially all of our assets. All principal plus accrued but unpaid interest on the line of credit is due August 31, 2007. All principal plus accrued but unpaid interest on the term loan is due December 31, 2009. We had no outstanding balance on the line of credit or the term loan as of October 28, 2006.

 

Contractual Obligations

 

The following table describes our commitments to settle contractual obligations as of April 30, 2006:
