Item 1. Business.

​

Acquisition of Telerob GmbH

​

On May 3, 2021, we purchased 100% of the issued and outstanding shares of Telerob Gesellschaft für Fernhantierungstechnik mbH, a German company based in Ostfildern (near Stuttgart), Germany (“Telerob”), including Telerob’s wholly owned subsidiary, Telerob USA, Inc. (“Telerob USA,” and collectively with Telerob, the “Telerob Group”) pursuant to a share purchase agreement with Unmanned Systems Investments GmbH, a German limited liability company incorporated under the laws of Germany (the “Seller”), and each of the unit holders of the Seller.

​

The disclosures and references in this Annual Report, including financial data, the description of our business operations in this Item 1, and risk factors related to our operations included in Item 1A include the Telerob Group acquisition, unless otherwise specifically noted. The assets, liabilities and results of operations of the Telerob Group have not been consolidated into our results as of and for the period ended April 30, 2021 or any of the historical periods presented.

​

Overview

​

We design, develop, produce, deliver and support a technologically-advanced portfolio of intelligent, multi-domain robotic systems and related services for government agencies and businesses. We supply unmanned aircraft systems (“UAS”), tactical missile systems (“TMS”), unmanned ground vehicles (“UGV”) and related services primarily to organizations within the U.S. Department of Defense (“DoD”) and to international allied governments. We derive the majority of our revenue from these business areas and we believe that the markets for these solutions offer the potential for significant long-term growth. Additionally, we believe that some of the innovative potential products, services and technologies in our research and development pipeline will emerge as new growth platforms in the future, creating additional market opportunities.

​

Our success with our current product and service offering stems from our investments in research and development to invent and deliver advanced solutions, utilizing proprietary and commercially available technologies, and in acquiring leading businesses that help our customers achieve their desired outcomes. We develop and acquire these highly innovative solutions by working very closely with our key customers to solve their most important challenges related to our areas of expertise. Our core technological capabilities, developed through more than 45 years of innovation, include robotics and robotics systems autonomy; sensor design, development, miniaturization and integration; embedded software and firmware; miniature, low power wireless digital communications; lightweight

Table of Contents

aerostructures; high-altitude systems design, integration and operations; machine vision, machine learning and autonomy; low SWaP (Size, Weight and Power) system design and integration; manned-unmanned teaming and unmanned-unmanned teaming; power electronics and electric propulsion systems; efficient electric power conversion, storage systems and high density energy packaging; controls and systems integration; vertical takeoff and landing flight, fixed wing flight and hybrid aircraft flight; image stabilization and target tracking; advanced flight control systems; fluid dynamics; human-machine interface development; and integrated mission solutions for austere or extreme environments.

​

Our business focuses primarily on the design, development, production, marketing, support and operation of innovative UAS, TMS and UGV that provide situational awareness, remote sensing, multi-band communications, force protection and other information and mission effects to increase the safety and effectiveness of our customers’ operations.

​

Our Strategy

​

As a technology solutions provider, our strategy is to grow our business by delivering innovative, safe and reliable multi-domain solutions that provide customers with valuable capabilities. Delivering these capabilities will enable us to create new markets or market segments, gain share in existing markets and grow as market adoption increases. We believe that by introducing new solutions, or acquiring differentiated solutions developed by others, that provide customers with compelling value, we can grow our business profitably, both in new and existing markets. By providing differentiated solutions we believe we can compete effectively against large, incumbent competitors that may possess advantages in scope, scale, resources and relationships.

​

We intend to grow our business by preserving a leadership position in our core UAS, TMS and UGV markets, and by creating or acquiring new solutions and capabilities that enable us to establish leadership positions in new markets. Key components of this strategy include the following:

​

Expand the market penetration of existing products and services. Our small and medium UAS, TMS and UGV enjoy leading positions in their respective markets. We intend to increase the penetration of our small and medium UAS and UGV products and services within the U.S. military, the military forces of allied nations, other government agencies and non-government organizations, including commercial entities, and to increase the penetration of our TMS within the U.S. military and within the military forces of allied nations. We believe that the broad adoption of our small and medium UAS and TMS by the U.S. military will continue to spur demand by allied nations, and that our efforts to pursue new applications are creating opportunities beyond the early adopter military market. Similarly, we expect the adoption of our UGV solutions to expand our presence in the U.S. military market.

​

Deliver innovative new solutions into existing and new markets. Customer-focused innovation is the primary driver of our growth. We plan to continue investing in internally-funded research and development projects while expanding our pursuit of customer-funded research and development projects to generate revenue and develop better, more capable products, services and business models, both in response to and in anticipation of emerging customer needs. In some cases, these innovations result in upgrades to existing offerings, expanding their value among existing customers and markets. In other cases, these innovations become entirely new solutions that position us to address new markets, customers and business opportunities. We believe focused research and development investments will allow us to deliver innovative new products and services that address market needs within and outside of our current target markets, and enable us to create new opportunities for growth. We view strategic partnerships as means by which to further the reach of our innovative solutions through access to new markets, customers and complementary capabilities. We also consider acquisitions as a method to obtain valuable products or technologies that can further enable our growth strategy.

​

Foster our entrepreneurial culture and continue to attract, develop and retain highly-skilled personnel. Our company culture encourages innovation and entrepreneurialism, which helps to attract and retain highly-skilled professionals. We intend to preserve this culture to encourage the development of the innovative, highly technical system solutions and business models that give us our competitive advantage. Our values of “customer commitment,” “trust and teamwork,” “innovate and simplify,” and “ownership and results” serve as the foundation of our culture. We believe that our values help to guide the behavior of our team members and serve to maintain a positive work

environment that inspires loyalty among them and customers. We also believe that our values facilitate the integration of new team members who join us as a result of acquisitions.

​

Preserve our agility and flexibility. We respond rapidly to evolving markets, solve complicated customer problems, and strive to deliver new products, services and capabilities quickly, efficiently and affordably relative to available alternatives. We believe our agility and flexibility help us to strengthen our relationships with customers and partners. We intend to maintain our agility and flexibility, which we believe to be important sources of differentiation when we compete against organizations with more extensive resources.

​

Effectively manage our growth portfolio for long-term value creation. Our production and development programs and services present numerous investment opportunities that we believe will deliver long-term growth by providing our customers with valuable new capabilities. We evaluate each opportunity independently and within the context of other investment opportunities to determine its relative cost, timing and potential for generation of returns, and thereby its priority. This process helps us to make informed decisions regarding potential growth capital requirements and supports our allocation of resources based on relative risks and returns to maximize long-term value creation, which is the key objective of our growth strategy. We also review our portfolio on a regular basis to determine if and when to narrow our focus on the highest potential growth opportunities.

​

Customers

​

We sell the majority of our UAS and services to organizations within the U.S. DoD, including the U.S. Army, Marine Corps, Special Operations Command, Air Force and Navy, and to allied governments. We sell our TMS and services to organizations within the U.S. DoD and allied military forces. We sell our UGV and services to U.S. and allied government military and public safety agencies as well as to commercial entities. We also develop High Altitude Pseudo-Satellite (“HAPS”) systems for SoftBank Corp. and HAPSMobile Inc., a commercial joint venture of which we own approximately 7%.

​

During our fiscal year ended April 30, 2021, we generated approximately 34% of our revenue from the U.S. Army pursuant to orders placed under contract by the U.S. Army on behalf of itself as well as for several other organizations within the DoD. Other U.S. government agencies and government subcontractors accounted for 27% of our sales revenue, and HAPSMobile Inc. accounted for 11% of our sales revenue. Sales revenue to other foreign customers, inclusive of foreign military sales made through the DoD, commercial and consumer customers accounted for the remaining 28% of sales revenue during our fiscal year ended April 30, 2021.

​

Technology, Research and Development

​

Technological Competence and Intellectual Property

​

Our company was founded by the late Dr. Paul B. MacCready, the former Chairman of our board of directors and an internationally renowned innovator who was instrumental in establishing our entrepreneurial and creative culture. This culture has consistently enabled us to attract and retain highly-motivated, talented employees and has established our reputation as an innovative leader in the industries in which we compete.

​

The innovations developed by our company and our founder include, among others: the world’s first effective human-powered and manned solar-powered airplanes; the first modern passenger electric car, the EV1 prototype for General Motors; the world’s highest flying airplane in level flight, Helios™, a solar-powered unmanned aircraft system that reached over 96,000 feet above sea level in 2001; Global Observer, the world’s first liquid hydrogen-fueled unmanned aircraft system; the Nano Hummingbird™, the world’s first flapping wing unmanned aircraft system capable of precise hover and omni-directional flight; and Blackwing™, the first submarine-launched unmanned aircraft system deployed by the U.S. Navy and a considerable portion of JPL/NASA’s Mars Ingenuity Helicopter, the first aircraft to perform a powered flight on another planet. The Smithsonian Institution possesses seven vehicles developed by our company or our founder in its permanent collection. Our history of innovation excellence is the result of our talented, creative and skilled employees whom we encourage to invent and develop innovative new solutions.

​

Table of Contents

A component of our ongoing innovation is a screening process that helps our business managers identify early market needs, which assists us in making timely investments into critical technologies necessary to develop solutions to address these needs. Similarly, we manage new product and business concepts through a commercialization process that balances spending, resources, time and intellectual property considerations against market requirements and potential returns on investment. Strongly linking our technology and business development activities to customer needs in attractive growth markets constitutes an important element of this process. Through the process we revisit our customer requirement assumptions to evaluate continued investment and to help ensure that our products and services deliver high value.

As of April 30, 2021, we had issued and retained 230 U.S. patents, as well as 58 pending U.S. patent applications; 15 active Patent Cooperation Treaty applications; and numerous foreign patents and pending applications. In many cases, when appropriate and to preserve confidentiality, we opt to protect our intellectual property through trade secrets as opposed to filing for patent protection.

​

The U.S. government has licenses to some of our intellectual property that was specifically developed in performance of government contracts, and may use or authorize others to use this intellectual property. In some cases, we fund the development of certain intellectual property to maximize its value and limit its use by potential competitors. While we consider the development and protection of our intellectual property to be integral to the future success of our business, at this time we do not believe that a loss or limitation of rights to any particular piece of our intellectual property would have a material adverse effect on our overall business.

​

Research, Development and Commercialization Projects

​

A core component of our business strategy is the focused development and commercialization of innovative solutions that we believe can become new products or services that enable us to create large new markets or accelerate the growth of our current markets. We invest in an active pipeline of these commercialization projects that range in maturity from technology validation to early market adoption. We cannot predict when, if ever, we will successfully commercialize these projects, or the exact level of capital expenditures they could require, which could be substantial.

​

Sales and Marketing

​

Our marketing strategy is based on establishing leadership positions in new markets that we create through the introduction or acquisition of innovation solutions that improve customer operational effectiveness and efficiency. Our ability to operate in an agile, flexible manner helps us achieve first mover advantage and work closely with early customers to achieve the successful adoption of our solutions.

Manufacturing and Operations

​

We pursue a lean and efficient production strategy across our business, focusing on rapid prototyping, supply chain management, final assembly, integration, quality and final acceptance testing. Using concurrent engineering techniques within an integrated product team structure, we rapidly prototype design concepts and products, while working to optimize our designs to meet manufacturing requirements, mission capabilities and customer specifications. Within this framework we develop our products with feedback and input from manufacturing, quality, supply chain management, key suppliers, logistics personnel and customers. We incorporate this input into product designs in an effort to maximize the efficiency and quality of our products while minimizing time to market. As a result, we believe that we significantly reduce the time required to move a product from its design phase to full rate production, while achieving high reliability, quality and yields.

​

We outsource certain production activities, such as the fabrication of certain aerostructures, the manufacture and assembly of electronic printed circuit boards, and payload components to qualified suppliers, with many of whom we have long-term relationships. This outsourcing enables us to focus on our core expertise of final assembly, system integration and test processes for our products, ensuring high levels of quality and reliability. We forge strong relationships with key suppliers based on their ability to grow with our production needs and support our growth plans. We continue to expand upon our suppliers’ expertise to improve our existing products and develop new solutions. We rely on both single and multiple suppliers for certain components and subassemblies. (See “Risk Factors—If critical components or raw materials used to manufacture our products become scarce or unavailable, then we may incur delays in manufacturing and delivery of our products, which could damage our business” for more information.) A majority of our production systems operate in accordance with our AS9100D registered Quality Management System, which is focused on continuous improvement in order to increase acceptance rates, reduce lead times and lower cost.

​

Customer Funded Research and Development

​

We actively pursue externally funded projects that help us to strengthen our technological capabilities. We submit bids to large research customers, such as the Defense Advanced Research Projects Agency, the U.S. Air Force, the U.S. Army and the U.S. Special Operations Command, for projects that we believe have the potential for future procurement. In some cases, commercial enterprises may fund our research and development activities, as with our HAPS UAS development program. Providing these services contributes to the development and enhancement of our technical competencies. We carefully manage the volume of customer funded research and development projects based on projects’ available resources, and expect to expand our team to support growth in this area of our business.

​

Seasonality

​

Historically our revenue in the second half of our fiscal years has exceeded our revenue in the first half of our fiscal years. The factors that affect our revenue recognition between accounting periods include the timing of new contract awards, the availability of U.S. government and international government funding, lead time to manufacture our family of systems to customer specification, customer acceptance and other regulatory requirements.

​

Raw Materials and Suppliers

​

Historically, we have not experienced significant delays in the supply or availability of our key raw materials or components provided by our suppliers; however, we have recently experienced shortages of certain components in our TMS product line which caused short term delays in production. Historically, we not experienced a significant price increase for raw materials or components. We believe all of these raw materials and components are available to meet our needs from various suppliers. We have not yet been materially impacted by the global shortage in semiconductor chips, but if the shortage were to worsen or continue for an extended period of time, we could experience material delays.

Diversity and Inclusion

​

At AeroVironment, creating a culture of diversity and inclusion is something we work on every day. We believe that a diverse workforce and an inclusive workplace is a major catalyst for driving innovation. We have focused our diversity and inclusion initiatives on employee recruitment, including investments in minority-serving institutions and outreach, employee training and development, such as efforts focused on expanding the diverse talent pipeline, and employee engagement, including through participation in employee focus groups on various topics related to diversity and inclusion.

​

Employee Safety and Health

​

Our safety and health program seeks to optimize our operations through targeted safety, health and wellness opportunities designed to ensure safe work conditions, create a healthy work environment, promote workforce resiliency and enhance business value. We have taken extraordinary measures to protect our workforce in response to the COVID-19 pandemic. We implemented extensive safety protocols to support our essential employees required to work onsite. Within our production and office areas we have established a number of safety protocols, including face covering and physical distance requirements, enhanced cleaning, encouraging daily self-health checks and voluntary temperature screening stations. We have implemented a flexible teleworking policy for employees who can meet our customer commitments remotely; a significant portion of our workforce began teleworking in mid-March 2020 and were continuing to telework as of June 15, 2021. In addition, we have sought to ensure that they have the technology, flexible work schedules, office equipment and other services needed during this time to enable them to work effectively from home. We have also implemented a coronavirus reporting mechanism for illness or exposure and positive COVID-19 tests. As part of that reporting process, we have developed a robust contact tracing program to identify employees who were in close contact with the ill employee in the workplace. We provide several channels for all employees to speak up, ask for guidance, and report concerns related ethics or safety violations. We address employee concerns and take appropriate actions that uphold our AeroVironment values.

​

Backlog

​

Consistent with ASC Topic 606, Revenue from Contracts with Customers (“ASC 606”), we define backlog as remaining unsatisfied performance obligations under firm orders for which work has not been performed. As of April 30, 2021 and 2020, our backlog was approximately $211.8 million and $208.1 million, respectively. We expect that approximately 94% of our backlog will be recognized as revenue during our fiscal year ending April 30, 2022.

​

In addition to our funded backlog, we also had unfunded backlog of $143.2 million and $122.0 million as of April 30, 2021 and 2020, respectively. Unfunded backlog does not meet the definition of a performance obligation under ASC Topic 606. We define unfunded backlog as the total remaining potential order amounts under cost reimbursable and fixed price contracts with (i) multiple one-year options and indefinite delivery, indefinite quantity (“IDIQ”) contracts, or (ii) incremental funding. Unfunded backlog does not obligate the customer to purchase goods or services. There can be no assurance that unfunded backlog will result in any orders in any particular period, if at all. Management believes that unfunded backlog does not provide a reliable measure of future estimated revenue under our contracts. Unfunded backlog, with the exception of the remaining potential value of the FCS domain, does not include the remaining potential value associated with a U.S. Army IDIQ-type contract for small UAS because values for each of the other domains within the contract have not been disclosed by the customer, and we cannot be certain that we will secure all task orders issued against the contract. Additionally, unfunded backlog on the SOCOM MEUAS contract reflects only those sites which have been awarded to Arcturus UAV, Inc. (“Arcturus”) and does not include the remaining potential value associated with the entire SOCOM MEUAV III/IV contract.

​

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

Our Business

​

Our business addresses the increasing value of intelligent, multi-domain robotic systems providing distributed, network-centric intelligence, surveillance and reconnaissance (“ISR”), communications, remote sensing, effects delivery and remote materials handling with innovative UAS, TMS and UGV solutions. With respect to the defense applications for these technologies, nearly 20 years of counterinsurgency operations in regions where U.S. and allied forces benefit from air and technical superiority have driven the demand for a variety of unmanned systems in the air and on the ground. The recent shift of U.S. and allied defense planning toward countering peer and near-peer adversaries requires a portfolio of capabilities that can operate effectively in areas where the battlespace, including the air, radio frequency spectrum and Global Positioning Satellite (“GPS”) signals, may be contested, driving the need for more intelligent robotic systems capable of autonomous operation.

​

Industry Background

​

Small and Medium UAS

​

The defense market for small and medium UAS has grown significantly since the early 2000s, driven largely by the demands associated with the global threat environment and resulting procurement by military customers, the early adopters for this technology. Small and medium UAS now represent accepted and enduring capabilities for military forces around the world. The U.S. military’s transformation into a smaller, more agile force that operates via a network of observation, communication and precision targeting technologies accelerated following the terrorist attacks of September 11, 2001, as it required improved, distributed observation and targeting of enemy combatants who operate in small groups, often embedded in dense population centers or dispersed in remote locations, to operate effectively in a counterinsurgency threat environment. We believe that UAS, which range from large systems, such as Northrop Grumman’s Global Hawk and General Atomics’ Predator, Sky Warrior, Reaper and Gray Eagle, to medium systems such as our Puma LE, T-20 and JUMP 20, Boeing’s ScanEagle and Integrator and Textron’s Shadow, to small systems, such as our Raven, Wasp AE, Puma AE, and VAPOR serve as integral components of today’s military force. These systems provide critical observation and communications capabilities serving the increasing demand for actionable intelligence, while reducing risk to individual “warfighters.” Small and medium UAS can provide real-time observation and communication capabilities to commanders and directly to the small units who control them. As airspace regulations in the U.S. and other nations evolve to accommodate the commercial use of small UAS, significant growth in the number of entities developing small UAS solutions is taking place.

Tactical Missile Systems

​

The development of weapons capable of rapid deployment and precision strike that also minimize the risk to surrounding civilians, property and operators has accelerated due to advances in enabling technologies. Weapons such as laser-guided missiles, “smart” bombs and GPS-guided artillery shells have dramatically improved the accuracy of strikes against hostile targets. When ground forces find themselves engaged in a firefight or near a hostile target, their ability to employ a precision weapon system quickly and easily can mean the difference between mission success and failure. A rapidly deployable solution could address emerging requirements beyond ground engagements for use in other types of missions and from a variety of sea, air and land platforms. We believe that embedding a precision lethal payload into a remotely controlled, portable delivery system provides warfighters with a valuable and more cost-effective alternative to existing munition and missile systems.

​

Unmanned Ground Vehicles

​

In situations where improvised explosive devices (“IEDs”), caustic chemicals, radiological or biological hazards or violent individuals represent significant danger to humans, UGVs can help responders remove, contain or neutralize these hazards without putting people in harm’s way. We believe that as enabling technologies continue to advance, UGVs will become more autonomous, more capable and more effective in dealing with hazardous threats, expanding the market potential for this set of applications to include non-defense applications such as facility security, infrastructure inspection, delivery of goods and many others.

​

High-Altitude Pseudo-Satellite (“HAPS”) UAS

​

We believe a market opportunity exists for HAPS UAS that can fly for months at a time to provide continuous remote sensing and communications in an affordable manner over great distances. Existing solutions such as terrestrial cellular towers, communications satellites and manned and unmanned aircraft address some of the emerging demand for this capability, but do so at relatively high financial and resource costs. Next generation mobile telephony, referred to as 5G, can use higher frequencies than those currently employed by 4G and LTE networks. These higher frequencies are not capable of traveling long distances as compared to the frequencies associated with existing networks. As a result, 5G deployment requires the installation of a large number of base stations and cellular towers to complement existing infrastructure, resulting in a significant investment of time, resources and capital. Geosynchronous satellites provide fixed, continuous communications capabilities to large portions of the globe, but they operate more than 20,000 miles from the surface of the earth, therefore limiting the bandwidth they can provide, introducing latency in communications signals and requiring relatively larger, higher power ground stations. Remote sensing satellites typically operate at lower altitudes, but are unable to maintain geosynchronous positions, meaning they are moving with respect to the surface of the earth, resulting in a limited presence over specific areas of interest and significant periods of time during which they are not present over those areas. A new category of constellations consisting of a large number of very small and low earth orbiting satellites is proposed to provide a lower cost alternative with more ubiquitous coverage for reconnaissance and communication, but is only beginning to be deployed in meaningful quantities and may not be capable of providing the uninterrupted service and quality required by commercial mobile carriers. High-altitude balloons carrying communication payloads are subject to wind direction and speed and, therefore, may not be able to deliver the continuous, uninterrupted service and connection quality required by commercial mobile carriers but may be suitable for other applications. UAS that are capable of operating in an affordable manner for extended periods of time over an area of interest without gaps in availability while carrying a communications or observation payload could help to satisfy this need.

​

Advanced Artificial Intelligence and Autonomy

​

Robotic systems designed to operate in complex environments, such as contested battlespaces or urban locations, will require advanced artificial intelligence capabilities to enable non-GPS navigation and higher levels of autonomy. For defense applications, this could require other navigation methods to ensure location accuracy and incorporating computer vision capabilities to respond to changes on the ground or in the air. Such higher levels of autonomy will become increasingly valuable to enable the effective use of robotic systems.

Our Solutions

​

We supply our UAS and TMS products and services to multiple customers within and outside of the United States, our TMS products and services to organizations within the U.S. government and allied nations and our UGV solutions to organizations in the U.S. and allied nations.

​

Small UAS Products

​

Our small UAS, including Raven, Wasp AE, Puma AE, Puma LE, VAPOR and Quantix Recon are designed to operate reliably at very low altitudes in a wide range of environmental conditions, providing a vantage point from which to collect and deliver valuable information. Military forces employ our small UAS to deliver ISR and communications, including real-time tactical reconnaissance, tracking, combat assessment and geographic data, directly to the small tactical unit or individual operator, thereby increasing flexibility in mission planning and execution. Our small UAS wirelessly transmit critical live video and other information generated by their payload of electro-optical, infrared or other sensors directly to a hand-held ground control unit, enabling the operator to view and capture images, during the day or at night, on the control unit. Our Quantix Recon mapping drone generates a volume of high-resolution data significantly larger than wireless bandwidth can accommodate, requiring the onboard storage and subsequent transfer of data once the air vehicle has landed. With the exception of Quantix Recon, our ground control systems allow the operator to control the aircraft by programming it for GPS-based autonomous navigation using operator-designated way-points, or by manual flight operation. The ground control systems are designed for durability and ease of use in harsh environments and incorporate a user-friendly, intuitive user interface. All of our fixed wing small UAS currently in production for military customers operate from our common ground control system. Our Quantix Recon system plots its own flight path and launches, flies and lands autonomously to complete its mission. Our VAPOR helicopter UAS currently employs a distinct portable ground control system.

​

We designed our small UAS to be transportable by as few as a single person, assembled in minutes and launched and operated by one or two people, with limited training required. The efficient and reliable electric motors used in all of our small UAS are powered by modular battery packs that can be replaced quickly, enabling rapid return to flight. We designed all of our small UAS to be reusable for hundreds of flights under normal operating circumstances and to be recovered through an autonomous landing feature that enables a controlled descent to a designated location.

​

In military applications, our small UAS provide forward aerial observation capabilities that enable tactical commanders to observe, for example, around the next corner, to the next intersection or past a ridgeline in real-time. This information facilitates faster, safer movement through urban, rural, riverine and mountainous environments and can enable troops to be proactive based on field intelligence rather than reactive to attack. Moreover, by providing this information, our systems reduce the risk to warfighters and to the surrounding population by providing the ability to tailor the military response to the threat. U.S. military personnel regularly use our small UAS, such as Raven, for missions such as force protection, combat observation and damage assessment. These reusable systems are easy to transport, assemble and operate and are relatively quiet when flying at typical altitudes of 300 to 500 feet above ground level, as a result of our efficient electric propulsion systems. Furthermore, their small size makes them difficult to see from the ground. In addition, the low cost of our small UAS relative to larger systems and alternatives makes it practical for customers to deploy these assets in large quantities, directly to warfighters.

​

In emerging commercial applications, our small UAS enable enterprises to manage valuable assets such as crops, powerlines and railroad infrastructure, more effectively and safely than previously possible. Our Quantix Mapper and VAPOR helicopter systems are designed to provide more accurate and timely information to individuals or organizations for more informed decision-making. Better and more timely information can translate into more efficient activities that facilitate more efficient use of resources such as maintenance operations.

​

Our small UAS offering also includes spare equipment, alternative payload modules, batteries, chargers, repair services and customer support. We provide training by our highly-skilled instructors, who typically possess extensive military experience, and continuous refurbishment and repair services for our products. By maintaining close contact with our customers and users in the field, we gather critical feedback on our products and incorporate that information

into ongoing product development and research and development efforts. This approach enables us to improve our solutions in response to, and in anticipation of, evolving customer needs.

​

Certain systems within our small UAS portfolio include multiple aircraft, our common and interoperable hand-held ground control system and an array of spare parts and accessories. Other systems, namely, Puma LE, VAPOR and Quantix Recon, consist of a single air vehicle, as well as a ground control system, spare parts and accessories. Our current small UAS portfolio for defense applications consists of the following aircraft:

​

(1) | Represents point-to-point minimum customer-mandated specifications for all operating conditions. In optimal conditions, the performance of our products may significantly exceed these specifications. Our digital data links (“DDL”) relay can enable operational modes that can extend range significantly.

​

The ground control system serves as the primary interface between the operator and our small UAS and allows the operator of each system, with the exception of Quantix Recon, to control the direction, speed and altitude of the aircraft as well as the orientation of the sensors to view the visual information they produce through real-time, streaming video and metadata. Our common ground control system interfaces with each of our fixed wing air vehicles, providing a common user experience. In addition to the thousands of air vehicles delivered to our customers, thousands of ground control systems are also in our customers’ hands.

​

Our line of miniature gimbaled sensor payloads provides small UAS operators with enhanced observation and target tracking functionality. Our DDL is integrated into Puma LE, Puma AE, Raven and Wasp AE systems, enhancing their capabilities, and ultimately, the utility of our small UAS by enabling more efficient radio spectrum utilization and communications security. Small UAS incorporating our DDL are optimized for the low-power, low-latency, and streaming bandwidth efficiency required for UAS. Additionally, our DDL enables each air vehicle to operate as an Internet-Protocol addressable hub capable of routing and relaying video, voice and data to and from multiple other nodes on this ad hoc network. This capability enables beyond line-of-sight operation of our small UAS, further enhancing their value proposition to our customers.

​

Medium UAS Products

​

Providing similar capabilities to our small UAS, our field-deployable medium UAS, including T-20 and JUMP 20, deliver extended endurance and expanded payload capacity to support a broader set of missions that benefit from aerial surveillance and the use of specialized payloads. The portable, hand or bungee-launched Puma LE can operate in ground and maritime environments. The internal combustion-powered T-20 and JUMP 20 offer significantly greater endurance and payload capacity than our small UAS, with larger airframes that can also accommodate a wider variety of payloads. The JUMP 20 launches and lands vertically as a result of its vertical take-off and landing (“VTOL”) rotors, minimizing the amount of space required for its operation. The T-20 launches from a catapult, lands on a short runway and provides more than 24 hours of endurance.

​

Tactical Missile Systems Products

​

Our TMS consist of tube-launched aircraft that deploy with the push of a button, fly at higher speeds than our small UAS, and perform either effects delivery or reconnaissance missions. Switchblade 300, the first of our TMS products, can be transported in its launch tube, within a backpack, and deployed within minutes to defend against lethal threats such as snipers and mortar launchers. With a high level of precision, including a customized warhead, patented wave-off, loiter and re-engagement capabilities, Switchblade 300 can neutralize a target rapidly and accurately without causing collateral damage. Furthermore, because it streams live electro-optical and thermal video to its operator, Switchblade 300 can be called off in the final moments prior to a strike should the situation require, potentially eliminating damage to non-combatants. Switchblade 600 is a larger version of Switchblade 300 that can fly for a longer period of time and over a longer distance while carrying a larger, more powerful, anti-armor warhead. Blackwing, a variant of Switchblade 300, launches from a submerged submarine and carries extra batteries instead of a warhead, providing longer flight time for extended maritime reconnaissance operations.

ISR Services

​

We currently operate our medium UAS, such as JUMP 20, in overseas locations to support U.S. military operations under ISR services contracts. Under these services contracts we deliver the information our medium UAS produce to our customers, who use that information to support their missions. These contracts specify a location and number of hours per month of services to perform. This contractor-owned, contractor-operated (“COCO”) arrangement represents a new business model for AeroVironment as a result of the acquisition of Arcturus and provides access to alternative customer funding sources, while also providing a way for customers who may not wish to own and operate their UAS to benefit from their differentiated capabilities. This COCO business model may expand to include other AeroVironment solutions in the future.

Unmanned Ground Vehicle Products

​

Our UGV support a variety of missions and applications, ranging from explosive ordnance disposal to hazardous materials handling and law enforcement operations. All of our UGVs feature secure communications, multi-axis manipulators and automatic tool exchange, which eliminates the need for the UGV to return to its operator to switch the tool attached to its manipulator arm. We also offer fully equipped service vehicles for the transport, service and operation of our UGV solutions. All of our UGVs feature the intuitive and operationally simplified Robo Command Ground Control System (GCS) with multi-touch screen, pre-programmed motion sequences and ergonomically designed hand controllers for precision control of the robot, manipulator and accessories.

Two of our UAS and TMS development initiatives are described below:

​

Tactical Missile System Variants. We pioneered our first rapidly deployable, high-precision TMS, named Switchblade, for use by defense ground forces. Switchblade 300 is now deployed by the U.S. military to provide force protection to its troops overseas in combat operations. During numerous demonstrations over the course of several years, multiple potential customers requested modifications to Switchblade 300 to accommodate their specific mission requirements. We performed a number of successful demonstrations and are now developing several variants of Switchblade 300 for new customers and applications, including deployment from sea and air vehicles. Blackwing, a submarine-

16

launched reconnaissance system, represents one of the variants that has now generated meaningful procurement demand. Another variant is Switchblade 600, a larger version that delivers longer endurance, greater range, a larger payload and more significant mission effects. We believe these new variants have the potential to expand our TMS opportunities significantly.

​

HAPS Unmanned Aircraft Systems. Building on our decades of groundbreaking development and demonstration of high altitude solar-powered UAS, in fiscal year 2018 we established a joint venture with SoftBank Corp. to create a global broadband and telecommunications company to demonstrate and deploy HAPS UAS around the world. As of April 30, 2021, AeroVironment owned a 7% share of HAPSMobile Inc., while SoftBank Corp. owned a majority 93% share. The joint venture is funding AeroVironment’s development and demonstration of solar-powered HAPS UAS. AeroVironment possesses exclusive rights to manufacture and supply the solar HAPS UAS developed by the joint venture to HAPSMobile Inc., subject to meeting contractual performance criteria. HAPSMobile Inc. possesses exclusive rights to market the solar HAPS UAS for commercial markets globally, while AeroVironment possesses exclusive rights to market the solar HAPS UAS for non-commercial markets globally, with the exception of Japan.

​

Sales and Marketing

​

Our Product Line Management organization translates customer and market requirements into multi-year product roadmaps that guide our development, engineering and manufacturing plans. We organize our U.S. business development team members by target market and customer, and we locate team members in close proximity to the customers they support, where possible. We organize our program managers by product and focus on designing optimal solutions and contract fulfillment, as well as internalizing feedback from customers and users. By maintaining assigned points of contact with our customers, we believe that we are able to maintain our relationships, service existing contracts effectively and gain vital feedback to improve our responsiveness and product offerings.

​

Manufacturing and Operations

​

Continued investment in infrastructure has established our manufacturing capability to meet demand with scalable capacity. We have the manufacturing infrastructure to produce products at rates higher than our historical volumes, support initial low rate production for new UAS development programs and TMS and execute initial low-rate production of large UAS. By drawing upon experienced personnel across various manufacturing industries including aerospace, automotive and volume commodities, we have instituted lean production systems and leverage our International Organization for Standardization (“ISO”) certification for Quality Management, integrated supply chain strategy, document control systems and process control methodologies for production. Presently, we perform small UAS manufacturing at the 85,000 square foot manufacturing facility we established in 2005. Our ISO 9001:2015 + AS9100D certified manufacturing facilities are designed to accommodate demand of up to 1,000 aircraft per month. ISO 9001:2015 + AS9100D refers to a set of voluntary standards for quality management systems. The 9001:2015 standards are established by the ISO to govern quality management systems used worldwide. We are regularly audited and certified to be compliant by a third party, accredited registrar. Accreditation of SAI Global, our third party registrar, is by the ANSI National Accreditation Board. These audits performed as part of certification evaluate the effectiveness of companies’ quality management systems and their compliance with ISO standards. Some companies and government agencies view ISO certification as a positive factor in supplier assessments.

​

Competition

​

The defense market for small UAS continues to evolve in response to changing technologies, shifting customer needs and expectations and the potential introduction of new products. We believe that a number of established domestic and international defense contractors have developed or are developing small UAS that continue to compete, or will compete, directly with our products. Some of these contractors have significantly greater financial and other resources than we possess. Our current principal small UAS competitors include Elbit Systems Ltd., Teledyne Technologies, Inc., L3 Technologies, Inc., and Lockheed Martin Corporation. We do not view large UAS such as Northrop Grumman Corporation’s Global Hawk or General Atomics, Inc.’s Predator and its derivatives as direct competitors to our small

17

Table of Contents

UAS because they perform different missions, do not typically deliver their information directly to front-line ground forces and are not hand-launched and controlled. However, we cannot be certain that these platforms will not become direct competitors in the future. Potential competition from consumer-focused drone manufacturers is emerging as their capabilities increase and their prices remain low relative to existing defense solutions, which is resulting in some level of military consideration even if such drones do not meet traditional military performance or security specifications. Such potential competitors include Skydio, Inc. and Shield AI.

​

The U.S. defense market for medium UAS has been addressed primarily by The Boeing Company’s ScanEagle and Textron Inc.’s Shadow UAS. Our current principal medium UAS competitors include those competing with us for the U.S. Army’s Future Tactical UAS (FTUAS) program: Martin UAV and Northrop Grumman’s V-Bat, Textron’s Aerosonde and L3Harris’ FVR-90. International medium UAS competitors include Elbit Systems Ltd. and Israeli Aircraft Industries. We do not view large UAS such as Northrop Grumman Corporation’s Global Hawk or General Atomics, Inc.’s Predator and its derivatives as direct competitors to our medium UAS because they perform different missions, require a larger logistical footprint and cost considerably more to procure and operate. However, we cannot be certain that these platforms will not become direct competitors in the future as we expand the capabilities of our medium UAS products to, potentially, impinge upon the lower end of the large UAS market segment.

​

The market for UGV spans the global defense, first responder, security and logistics market segments. The UGV opportunity in the U.S. Department of Defense has grown with recent U.S. Army procurement awards and a pending U.S. Air Force program. Competitors in the U.S. UGV market include L3Harris Technologies, Inc., Teledyne Technologies, Inc., QinetiQ North America, Inc., Peraton/Remotec, ICOR and Boston Dynamics. Initial adoption of UGVs for law enforcement and other government agencies is also progressing in the U.S. and globally, as well as applications in hazardous materials handling.

​

The market for HAPS UAS is in an early stage of development. As a result, this category is not well defined and is characterized by multiple potential solutions. An existing contractor that claims to provide high altitude long endurance UAS is Northrop Grumman Corporation with its Global Hawk. Several aerospace and defense contractors have pursued this market opportunity with proposed very long duration UAS, including The Boeing Company, Airbus, Lockheed Martin Corporation and Northrop Grumman Corporation. Companies pursuing airships (high altitude aircraft that are kept buoyant by a body of gas that is lighter than air) as a solution for this market include Lockheed Martin Corporation and Northrop Grumman Corporation. A number of telecommunications, aerospace and technology companies, including AeroVironment and HAPSMobile Inc. launched the HAPS Alliance to promote the benefits of HAPS to the global population. Companies pursuing conventional satellites as a solution for this market include The Boeing Company, Lockheed Martin Corporation, General Dynamics Corporation, EADS N.V., Ball Corporation and Northrop Grumman Corporation. Companies pursuing Low Earth Orbit (“LEO”), micro or cubesat satellite constellations for global communication and remote sensing include Amazon, OneWeb, SpaceX and The Boeing Company. Companies owning and operating terrestrial cellular tower networks include American Tower Corporation, Crown Castle International Corp. and SBA Communications Corporation.

​

The market for TMS is in an early stage of development, but it is evolving rapidly. Competitors in this market include Textron Inc., Raytheon Technologies, Lockheed Martin Corporation and Uvision.

​

The market for commercial UAS products and services is in an early stage of development, but is evolving rapidly, generating a great deal of interest as government regulations evolve to accommodate commercial UAS operations in the National Airspace System and in the airspace systems of other countries. Given the breadth of applications and the diversity of industries that could benefit from UAS technology, a growing number of potential competitors in this market include consumer drone manufacturers such as Dà-Jiāng Innovation, who seek to enhance their systems’ capabilities over time; other small UAS manufacturers, including large aerospace companies such as Lockheed Martin Corporation, and drone and aerial surveying and mapping service providers such as PrecisionHawk, Sentera and SlantRange; ground-based surveying and mapping service providers; satellite imagery providers; and specialty system manufacturers, software as a service and other service providers aiming to address specific market segments. The emerging non-military market is attracting numerous additional competitors and significant venture capital funding given perceived lower barriers to entry and a much more fragmented marketplace as compared to the military market. Potential additional competitors include start-up companies providing low cost solutions.

18

Table of Contents

​

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

​

Regulation

​

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

​

Certain of these regulations impose substantial penalties for violations, including suspension or debarment from government contracting or subcontracting for a period of time. We monitor all of our contracts and contractual efforts to minimize the possibility of any violation of these regulations.

​

In addition, we are subject to industry-specific regulations due to the nature of the products and services we provide. For example, certain aspects of our business are subject to further regulation by additional U.S. government authorities, including (i) the Federal Aviation Administration (“FAA”), which regulates airspace for all air vehicles in the U.S. National Airspace System, (ii) the National Telecommunications and Information Administration and the Federal Communications Commission, which regulate the wireless communications upon which our UAS depend in the United States and (iii) the Defense Trade Controls of the U.S. Department of State that administers the International Traffic in Arms Regulations, which regulate the export of controlled technical data, defense articles and defense services.

​

On June 21, 2016 the FAA released its final rules that allow routine use of certain small UAS in the U.S. National Airspace System. The FAA rules, which went into effect in August 2016, provide safety rules for small UAS (under 55 pounds) conducting non-recreational operations. The rules limit flights to visual-line-of-sight daylight operation, unless the UAS has anti-collision lights in which case twilight operation is permitted. The final rule also addresses height and speed restrictions, operator certification, optional use of a visual observer, aircraft registration and marking and operational limits, including prohibiting flights over unprotected people on the ground who are not directly participating in the operation of the UAS. Current FAA regulations require drone operators to register their systems with the FAA and secure operating licenses for their drones as per the Part 107 specifications. These regulations continue to evolve to accommodate the integration of UAS into the national airspace system for commercial applications, including HAPS UAS.

​

In December 2019, the FAA proposed rules requiring the remote identification of UAS. Remote identification, which provides for a UAS in flight to provide identification that can be received by other parties, is designed to enhance safety and security by allowing the FAA and other agencies to identify a UAS that appears to be flying unsafely or in an area in which flight is not permitted. The public comment period for the proposed rules expired on March 2, 2020. On April 21, 2021, the final rule for remote identification of UAS went into effect. On the same day, the final rule for operation of small UAS over people also went into effect. This rule permits routine operations of small unmanned aircraft over people, moving vehicles, and at night under certain conditions. The final rule also makes changes to the recurrent testing framework and expands the list of persons who may request the presentation of a remote pilot certificate. Additionally, in February 2020, the FAA issued a public request for comment on its proposed policy for the creation of a new type certification of certain UAS as a special class of aircraft under FAA regulations. Currently the Part 107 Rules allow for the operation of small UAS without the need for FAA airworthiness certification as long as the UAS meets certain specified criteria and certain flight rules are followed; larger UAS and operations of small UAS outside the scope of the Part 107 Rules require a waiver from the FAA. The FAA’s proposed policy proposes a new

19

Table of Contents

special class of UAS for which airworthiness certification can be obtained, however, the proposed policy only applies to the procedures for the type certification of the new class of UAS, not the criteria that will be needed for the UAS or the flight operations to be followed to operate. Further rulemaking by the FAA is anticipated regarding the particular criteria for the airworthiness certification standards under the new special class proposed by the new policy. The comment period for the FAA’s proposed policy expired on March 4, 2020.

​

While it is currently anticipated that the enactment of remote identification, operation of small UAS over people, and a new airworthiness certification process for a newly created special class of UAS will help formalize the process for manufacturing and obtaining airworthiness certification for UAS within the newly created class and accelerate the development of commercial UAS in the U.S., it is uncertain whether the FAA’s actions, if any, will have such effects. Additionally, it is unclear when, if ever, the FAA will implement final rules regarding remote UAS identification and whether they will differ from the proposed rules. It is also unclear when, if at all, the FAA will create a new class of UAS and what the final rules regarding the certification of such UAS will look like. We cannot be certain as to how our business will be affected by the FAA’s proposals until the final rules for such matters are issued by the FAA.

​

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

​

Government Contracting Process

​

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

​

Bidding Process

​

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

​

Funding

​

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

​

The U.S. military funds its contracts for our full-rate production UAS either through operational need statements or as programs of record. Operational need statements require allocations of discretionary spending or reallocations of funding from other government programs. Funding for our production of initial Raven system deliveries, for example, was provided through operational need statements. We define a program of record as a program which, after undergoing extensive DoD review and product testing, is included in the five-year government budget cycle, meaning that funding is allocated for purchases under these contracts during the five-year cycle, absent affirmative action by the customer or Congress to change the budgeted amount. Despite being included in the five-year budget cycle, funding for these programs is subject to annual approval.

​

Material Government Contract Provisions

​

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

​

| ● | terminate existing contracts for convenience, in whole or in part, when it is in the interest of the government to do so;

​

| ● | terminate contracts for default upon the occurrence of certain enumerated events;

​

| ● | unilaterally modify contracts with regard to certain performance requirements;

​

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

​

| ● | potentially obtain rights in, or ownership to, intellectual property associated with products and systems developed or delivered by a contractor as a result of its performance of the contract;

​

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

​

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

​

| ● | control or prohibit the export of certain items.

​

Generally, government contracts are subject to oversight audits by government representatives. Compensation, if any, in the event of a termination for default is limited to payment for work completed at the time of termination. In the event of a termination for convenience, the contractor may receive the contract price for completed work, as well as its costs of performance of terminated work including an allowance for profit and reasonable termination settlement costs.

​

Government Contract Categories

​

There are three primary types of government contracts in our industry, each of which involves a different payment methodology and level of risk related to the cost of performance. These basic types of contracts are typically referred to as fixed-price contracts, cost reimbursable contracts, including cost-plus-fixed fee, cost-plus-award fee, and cost-plus-incentive fee, and time-and-materials contracts.

​

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

​

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

​

21

Table of Contents

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

​

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

​

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

​

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

​

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

​

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

​

Indefinite Delivery Indefinite Quantity Contract Form

​

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

​

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

22

Table of Contents

​

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

| ● | We could be prohibited from shipping our products to certain countries if we are unable to obtain U.S. government authorization regarding the export of our products, or if current or future export laws limit or otherwise restrict our business. In addition, failure to comply with export laws could result in fines, export restrictions and other sanctions and penalties.

| ● | Failure to obtain necessary regulatory approvals from the FAA or other governmental agencies, or limitations put on the use of small UAS in response to public privacy concerns, may prevent us from expanding the sales of our small UAS to non-military customers in the United States.

| ● | Our business may be dependent upon our employees obtaining and maintaining required security clearances, as well as our ability to obtain security clearances for the facilities in which we perform sensitive government work.

| ● | As a manufacturer of commercial UAS, we are subject to various government regulations and may be subject to additional regulations in the future, violation of which could subject us to sanctions or otherwise harm our business.

| ● | We are subject to pending legal proceedings that may disrupt our business, cause us to incur substantial costs, expose us to significant legal liabilities and could have a material adverse impact on our financial performance.

| ● | Our business is subject to federal, state and international laws regarding data protection, privacy, and information security, as well as confidentiality obligations under various agreements, and our actual or perceived failure to comply with such obligations could damage our reputation, expose us to litigation risk and adversely affect our business and operating results.

​

Risks Related to Our Intellectual Property

​

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

| ● | 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.

​

Risks Related to Securities Markets and Investment in Our Stock

​

| ● | Our management, whose interests may not be aligned with yours, is able to exert significant influence over all matters requiring stockholder approval.

| ● | Delaware law and anti-takeover provisions in our organizational documents may discourage our acquisition by a third party, which could make it more difficult to acquire us and limit your ability to sell your shares at a premium.

Risks Related to Our Business and Industry

​

We rely heavily on sales to certain customers, including the U.S. government, particularly to agencies of the Department of Defense, and HAPSMobile, Inc. and SoftBank Corp. related to our design and development of HAPS UAS.

​

Historically, we have derived a significant portion of our total sales and our small UAS and TMS sales from the U.S. government and its agencies. Additionally, more recently, we have derived a significant portion of our revenue from contracts with HAPSMobile, Inc. and SoftBank Corp. related to our design and development of HAPS UAS. Sales to the U.S. government, either as a prime contractor or subcontractor and inclusive of foreign military sales, represented approximately 69% of our revenue for the fiscal year ended April 30, 2021. The DoD, our principal U.S. government customer, accounted for approximately 27% of our revenue for the fiscal year ended April 30, 2021. We believe that the success and growth of our business for the foreseeable future will continue to depend to a significant degree 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, including constraints on government spending imposed by the Balanced Budget Act of 2019 and its subsequent amendments, 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 and that our business will not decline. Additionally, if annual budget appropriations or continuing resolutions are not enacted timely, we could face U.S. government shutdowns, which could adversely impact our programs and contracts with the U.S. government, our ability to receive timely payment from U.S. government entities and our ability to timely obtain export licenses for our products to fulfill contracts with our international customers.

​

The U.S. military funds our contracts primarily through operational needs statements, and to a lesser extent, through programs of record, which provides us with less visibility and certainty on future funding allocations for our contracts. Furthermore, all of our contracts with the U.S. government are terminable by the U.S. government at will. A significant decline in government expenditures generally, or with respect to programs for which we provide products, could adversely affect our business and prospects. Our operating results may also be negatively impacted by other developments that affect these government programs generally, including the following:

​

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

​

25

Table of Contents

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

​

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

​

| ● | delays or changes in the government appropriations and budget process;

​

| ● | uncertainties associated with the current global threat environment and other geo-political matters; and

​

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

​

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

​

In fiscal year 2021, HAPSMobile accounted for 11% of our total revenue. In May 2021, we and HAPSMobile mutually agreed to terminate our Design and Development Agreement and we entered into a Master Design and Development Agreement with SoftBank to continue design and development work on HAPS UAS. The Master Design and Development Agreement allows SoftBank to terminate the contract at its convenience for any reason. The termination of this contract or the loss of revenues from programs with HAPSMobile and/or SoftBank related to the design and development of HAPS UAS, could cause our revenue to decline and materially adversely affect our results of operations.

​

A decline in the U.S. and other government budgets, changes in spending or budgetary priorities, or delays in contract awards may significantly and adversely affect our future revenue.

​

Because we generate a significant portion of our total sales and our small and medium UAS and TMS sales from the U.S. government and its agencies, our results of operations could be adversely affected by government spending caps or changes in government budgetary priorities, as well as by delays in the government budget process, program starts, or the award of contracts or orders under existing contracts. As a result, our business may be impacted due to shifts in the political environment and changes in the government and agency leadership positions under the new U.S. administration. We cannot assure you that current levels of congressional funding for our products and services will continue and that our business will not decline. If annual budget appropriations or continuing resolutions are not enacted timely, we could face U.S. government shutdowns, which could adversely impact our programs and contracts with the U.S. government, our ability to receive timely payment from U.S. government entities and our ability to timely obtain export licenses for our products to fulfill contracts with our international customers.

​

Additionally, there is a possibility that political decisions made by the new U.S. administration, or an impasse on policy issues, could impact future spending and program authorizations may not increase or may decrease or shift to programs in areas in which we do not provide products or services or are less likely to be awarded contracts. Such changes in spending authorizations and budgetary priorities may occur as a result of shifts in spending priorities from defense-related and other programs as a result of competing demands for federal funds and the number and intensity of military conflicts or other factors.

​

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

​

Over the last decade, operational activity in Afghanistan and Iraq led to adoption and an increase in demand for our small UAS. More recently, the U.S. military has reduced its presence and operational activity in Afghanistan and Iraq, reducing demand for certain of our small UAS products from prior levels. We cannot predict whether the reduction in overseas operational levels will continue, how future procurement priorities related to defense transformation will be impacted or how changes in the threat environment will impact opportunities for our UAS business, including the ISR services we provide, in terms of existing, additional or replacement programs. If defense transformation or overseas

26

Table of Contents

operations cease or slow down, then our business, financial condition and results of operations could be impacted negatively.

​

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

​

Our UAS are sold in new and rapidly evolving markets. The commercial UAS market is in the early stages of customer adoption. The market for HAPS UAS is also in an early stage of development. Accordingly, our business and future prospects may be difficult to evaluate. We cannot accurately predict the extent to which demand for our products and services will increase, if at all. The challenges, risks and uncertainties frequently encountered by companies in rapidly evolving markets could impact our ability to do the following:

​

| ● | generate sufficient revenue to maintain profitability;

​

| ● | acquire and maintain market share;

​

| ● | achieve or manage growth in our operations;

​

| ● | develop and renew contracts;

​

| ● | attract and retain additional engineers and other highly-qualified personnel;

​

| ● | successfully develop and commercially market new products and services;

​

| ● | adapt to new or changing policies and spending priorities of governments and government agencies; and

​

| ● | access additional capital when required and on reasonable terms.

​

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 Elbit Systems Ltd., Teledyne Technologies, Inc., L3 Technologies, Inc. and Lockheed Martin Corporation. Our principal medium UAS competitors include Martin UAV and Northrop Grumman’s V-Bat, Textron, Inc.’s Aerosonde and L3 Harris Technologies’ FVR-90, Elbit Systems Ltd. and Israeli Aircraft Industries. We do not view large UAS such as Northrop Grumman Corporation’s Global Hawk or General Atomics, Inc.’s Predator and its derivatives as direct competitors to our small UAS because they perform different missions, do not typically deliver their information directly to front-line ground forces, and are not hand launched and controlled. We do not view large UAS such as Northrop Grumman Corporation’s Global Hawk or General Atomics, Inc.’s Predator and its derivatives as direct competitors to our medium UAS because they perform different missions, require a larger logistical footprint and cost considerably more to procure and operate. However, we cannot be certain that these platforms will not become direct competitors to our small and medium UAS in the future. Potential competition from consumer-focused drone manufacturers is emerging as their capabilities increase and their prices remain low relative to existing defense solutions, which is resulting in some level of military consideration even if such drones do not meet traditional military performance or security specifications. Our competitors in the U.S. defense market for UGVs include L3 Harris Technologies, Inc., Teledyne Technologies, Inc., QinetiQ North America, Inc., Peraton/Remotec, ICOR and Boston Dynamics.

​

The HAPS UAS market is in an early stage of development and our HAPS UAS faces competition from several aerospace and defense contractors and internet technology companies pursuing the high altitude long endurance UAS market for global communication and remote sensing, including The Boeing Company, Airbus, Lockheed Martin Corporation and Northrop Grumman Corporation, and competition from companies pursuing alternative solutions for this market such as Lockheed Martin Corporation and Northrop Grumman Corporation with airships (high altitude

27

Table of Contents

aircraft that are kept buoyant by a body of gas that is lighter than air) and companies pursuing conventional satellites and LEO micro or cubesat satellite constellations. Our TMS business faces competition from competitors including Textron Inc., Raytheon Technologies and Lockheed Martin Corporation.

​

Some of these firms have substantially greater financial, management, research and marketing resources than we have. Our UAS services business also faces competition from smaller businesses that can provide training and logistics services for multiple UAS platforms, including our small and medium UAS.

​

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, manufacture in high volumes more efficiently, divert sales away from us by winning broader contracts or hire away our employees by offering more lucrative compensation packages. Small business competitors may be able to offer more cost competitive solutions, due to their lower overhead costs, and take advantage of small business incentive and set-aside programs for which we are ineligible. The market for small UAS and UGV products and services is expanding, and competition intensifying 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 UAS, UGV, TMS, and commercial UAS markets do not experience significant growth, if we cannot expand our customer base or if our products and services do not achieve broad acceptance, then we may not be able to achieve our anticipated level of growth.

​

We cannot accurately predict the future growth rates or sizes of the markets for our products and services. Demand for our products and services may not increase, or may decrease, either generally or in specific markets, for particular types of products and services or during particular time periods. We believe the market for commercial UAS is nascent. 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 our UAS, UGV and TMS. Although we have expanded our UAS customer base to include foreign governments and domestic non-military agencies, and made our first approved export of our tactical missile systems to a foreign customer, we cannot assure you that our continued efforts to further increase our sales to international customers will be successful. The expansion of the UAS, UGV, TMS, and commercial UAS markets in general, and the market for our products and services in particular, depends on a number of factors, including the following:

​

| ● | customer satisfaction with these types of systems as solutions;

​

| ● | the cost, performance and reliability of our products and products offered by our competitors;

​

| ● | customer perceptions regarding the effectiveness and value of these types of systems;

​

| ● | limitations on our ability to market our UAS and TMS products and services outside the United States due to U.S. government regulations;

​

| ● | obtaining timely regulatory approvals, including, with respect to any of our unmanned systems, access to airspace and wireless spectrum; and

​

| ● | marketing efforts and publicity regarding these types of systems and services.

​

28

Table of Contents

Even if UAS, UGV, TMS, and commercial UAS gain wide market acceptance, our products and services may not adequately address market requirements and may not continue to gain market acceptance. If these types of systems generally, or our products and services 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 decline.

​

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

​

We derived approximately 39% of our revenue from international sales, including U.S. government foreign military sales in which an end user is a foreign government, during the fiscal year ended April 30, 2021 compared to 45% for the fiscal year ended April 30, 2020. We expect to continue to derive a significant portion of our revenue from international sales, and have now initiated international operations with the acquisition of Telerob Gesellschaft für Fernhantierungstechnik mbH, a German company (“Telerob”). Our international revenue and operations are subject to a number of material risks, including the following:

​

| ● | the unavailability of, or difficulties in obtaining any, necessary U.S. governmental authorizations for the export of our products to certain foreign jurisdictions;

​

| ● | regulatory requirements that may adversely affect our ability to operate in foreign jurisdictions, sell certain products or repatriate profits to the United States;

​

| ● | the complexity and necessity of using foreign representatives and consultants;

​

| ● | the complexities of operating a business in an international location through a subsidiary or joint venture structure that may include foreign business partners, subcontractors and suppliers;

​

| ● | the complexities of managing a workforce under foreign labor and employment law and related organizational requirements;

​

| ● | the complexity of shipping our products internationally through multiple jurisdictions with varying legal requirements;

​

| ● | difficulties in enforcing agreements and collecting receivables through foreign legal systems and other relevant legal issues, including fewer legal protections for intellectual property;

​

| ● | potential fluctuations in foreign economies and in the value of foreign currencies and interest rates;

​

| ● | potential preferences by prospective customers to purchase from local (non-U.S.) sources;

​

| ● | general economic and political conditions in the markets in which we operate;

​

| ● | laws or regulations relating to non-U.S. military contracts that favor purchases from non-U.S. manufacturers over U.S. manufacturers;

​

| ● | the imposition of tariffs, embargoes, export controls and other trade restrictions; and

​

| ● | different and changing legal and regulatory requirements, including those pertaining to anti-corruption, anti-boycott, data protection and privacy, employment law, intellectual property, contracts and tax in the jurisdictions in which we currently operate or may operate in the future.

​

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, destabilization of performance, 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. While we have adopted policies and procedures to

29

Table of Contents

facilitate compliance with laws and regulations applicable to our international operations and sales, our failure, or the failure by our employees or others working on our behalf, to comply with such laws and regulations may result in administrative, civil or criminal liabilities, including fines, suspension or debarment from government contracts or suspension of our export privileges. Moreover, our sales, including sales to customers outside the United States, substantially all are denominated in U.S. 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.

​

If we are unable to manage the increasing complexity of our business or achieve or manage our expected growth, our business could be adversely affected.

​

The complexity of our business has increased significantly over the last several years. We have expanded the number of product lines being pursued, shifting from primarily a U.S. government focused business to a business that includes substantial international product sales and added commercial services and formed a joint venture with SoftBank Corp. to develop HAPS UAS. We also acquired Pulse Aerospace, LLC, a Kansas-based developer of UAS capable of VTOL, in June 2019, followed by acquisitions of Arcturus, which designs, engineers, tools, manufactures and provides UAS and related products and services, and certain assets of the Intelligent Systems Group business segment (“ISG”) of Progeny Systems Corporation, which develops artificial intelligence-enabled computer vision, machine learning and perceptive autonomy technologies and provides related services, in February 2021. Additionally, in May 2021, we acquired Telerob, which develops, manufactures, sells, and services remote-controlled unmanned ground robots and transport vehicles for civil and defense applications. Further, in conjunction with the acquisition of Arcturus, we entered into certain credit facilities that include affirmative and negative covenants and place some restrictions on how we operate our business. These have increased complexity and our expected growth has placed, and will continue to place, a strain on our management and our administrative, operational and financial infrastructure. We anticipate further growth of headcount and facilities will be required to address expansion in our product and service offerings and the geographic scope of our customer base. However, if we are unsuccessful in our efforts, our business could decline. Our success will depend in part upon the ability of our senior management to manage our increased complexity and expected 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 experience declines.

​

To support our expected 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.

​

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

​

The U.S. military represents our largest source of revenue. We have, however, expanded our product sales into market segments, including those served by our unmanned ground vehicle product line and by our joint venture with SoftBank Corp. to develop HAPS UAS for global communication and remote sensing applications. Our efforts to expand our product offerings beyond our traditional markets 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.

​

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 and services 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

30

Table of Contents

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 and services, 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 and services 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 services and enhance existing products. We spent $53.8 million, or 14% of our revenue, in our fiscal year ended April 30, 2021 on internal research and development activities. We believe that there are significant investment opportunities in a number of business areas. Because we account for internal research and development as an operating expense, these expenditures will adversely affect our earnings in the future. Further, our research and development programs may not produce successful results, and our new products and services may not achieve market acceptance, create additional revenue or become profitable, which could materially harm our business, prospects, financial results and liquidity.

​

Our products and services 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 products rely on complex avionics, sensors, user-friendly interfaces and tightly-integrated, electromechanical designs to accomplish their missions. 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 products could result in injury, death or property damage and significantly damage our reputation and support for our products in general. We anticipate this risk will grow as our products begin to be used in U.S. domestic airspace and urban areas. We also remain liable for warranty and product liability claims for our EV charging systems and power cycling and test systems sold by us prior to our sale of our efficient energy systems business segment (our “EES Business”) to Webasto Charging Systems, Inc. (“Webasto”) in June 2018 as contemplated by the purchase and sale agreement between the parties, which products have the potential to cause injury, death or property damage in the event that they are misused, malfunction or fail to operate properly due to unknown defects or errors.

​

Although we maintain insurance policies, we cannot provide assurance 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.

​

If critical components or raw materials used to manufacture our products or used in our development programs become scarce or unavailable, then we may incur delays in manufacturing and delivery of our products and in completing our development programs, which could damage our business.

​

We obtain hardware components, various subsystems and systems from a limited group of suppliers, some of which are sole source suppliers. We do not have long-term agreements with any of these suppliers that obligate them to continue to sell components, subsystems, systems or products to us. Our reliance on these suppliers involves significant risks and uncertainties, including whether our suppliers will provide an adequate supply of required components, subsystems, or systems of sufficient quality, will increase prices for the components, subsystems or systems and will perform their obligations on a timely basis.

​

In addition, certain raw materials and components used in the manufacture of our products and in our development programs are periodically subject to supply shortages, and our business is subject to the risk of price increases and periodic delays in delivery. Particularly, the market for electronic components is experiencing increased demand and a global shortage of semiconductors, creating substantial uncertainty regarding our suppliers’ continued production of key components for our products. In the fourth quarter of our fiscal year ended April 30, 2021, we experienced shortages of certain components for our TMS product line, which caused short term delays in production and negatively affected our revenue for our fourth quarter and fiscal year ended April 30, 2021. If any additional shortages occur and 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 timely complete development programs or 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, or otherwise unable or unwilling to provide us with raw materials or components, 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. In particular, governmental measures responsive to the global COVID-19 pandemic have disrupted manufacturing and some supply chains, including our supply chain, which has had, and is expected to continue to have, a significant impact, both direct and indirect, on businesses and commerce worldwide. Although we have not yet seen significant delays from our suppliers and we keep stock of all our raw materials and other product components with long lead times to assist in the event that our supply chain is disrupted, if the COVID-19 outbreak continues and results in a prolonged period of commercial and/or governmental restrictions, this may impact our ability to obtain certain raw materials and certain components used in the manufacture of our products and in our development programs.

​

Earnings and cash flows can be impacted by changes in tax laws.

​

As a U.S.-based multinational business, we are subject to income tax in the U.S. and numerous jurisdictions outside the U.S. The relevant tax rules and regulations are complex, often changing and, in some cases, are interdependent. If these or other tax rules and regulations should change, the company’s earnings and cash flows could be impacted. In particular, the changes proposed by the new U.S. administration, including increasing the U.S. corporate income tax rate from 21% to 28%, doubling the rate of tax on certain earnings of non-U.S. subsidiaries and the imposition of a 15% minimum tax on worldwide book income, could materially affect the company’s financial results if enacted. The company’s worldwide provision for income taxes is determined, in part, through the use of significant estimates and judgments. Numerous transactions arise in the ordinary course of business where the ultimate tax determination is uncertain. The company undergoes tax examinations by tax authorities on a regular basis. While the company believes its estimates of its tax obligations are reasonable, the final outcome after the conclusion of any tax examinations and any litigation could be materially different from what has been reflected in the company’s historical financial statements.

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 involve 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 decline. 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.

​

We use estimates in accounting for many of our programs and changes in our estimates could adversely affect our future financial results.

​

Contract accounting requires judgments relative to assessing risks, including risks associated with estimating contract transaction prices and costs, assumptions for schedule and technical issues, customer-directed delays and reductions in scheduled deliveries, and unfavorable resolutions of claims and contractual matters. Due to the size and nature of many of our contracts, the estimation of total costs at completion is complicated and subject to many variables. For example, we must make assumptions regarding the length of time to complete the contract because costs also include expected increases in wages and prices for materials; and consider incentives or penalties related to performance on contracts and include them in the variable consideration to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the related uncertainty is resolved. Because of the significance of the judgments and estimation processes described above, it is likely that materially different amounts could be recorded if we used different assumptions or if the underlying circumstances were to change. Changes in underlying assumptions, circumstances or estimates may adversely affect our future results of operations and financial condition.

​

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

​

Fixed-price contracts (including both government and commercial contracts) represented approximately 78% of our revenue for the fiscal year ended April 30, 2021. 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. Because many of our contracts involve advanced designs and innovative technologies, we may experience unforeseen technological difficulties and cost overruns. 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 senior management and key employees, including key employees of business recently acquired, 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 future profitability may be dependent upon achieving cost reductions and projected economies of scale from increasing manufacturing quantities of our products. Failing to achieve such reductions in manufacturing costs and projected economies of scale could materially adversely affect our business.

​

We have limited experience manufacturing UAS and UGV in high volume. We do not know whether or when we will be able to develop efficient, low-cost manufacturing capabilities and processes that will enable us to manufacture (or contract for the manufacture of) these products in commercial quantities while meeting the volume, speed, quality, price, engineering, design and production standards required to successfully market our products. Our failure to develop such manufacturing processes and capabilities in locations that can efficiently service our markets could have a material adverse effect on our business, financial condition, results of operations and prospects. Our future profitability is, in part, dependent upon achieving increased savings from volume purchases of raw materials and component parts, achieving acceptable manufacturing yield and capitalizing on machinery efficiencies. We expect our suppliers to experience a sharp increase in demand for their products. As a result, we may not have reliable access to supplies that we require or be able to purchase such materials or components at cost effective prices. There is no assurance that we will ever be in a position to realize any material, labor and machinery cost reductions associated with higher purchasing power and higher production levels. Failure to achieve these cost reductions could adversely impact our business and financial results.

​

We face significant risks in the management of our inventory, and failure to effectively manage our inventory levels may result in product recalls or supply imbalances that could harm our business.

​

We maintain a variety of parts and components in inventory to allow us to customize our UAS products for specific customer requirements, which parts are subject to obsolescence and expiration. Due to the long-lead time for obtaining certain UAS product components and the manufacturing cycles, we need to make forecasts of demand and commit significant resources towards manufacturing our products. As such, we are subject to significant risks in managing the inventory needs of our business during the year, including estimating the appropriate demand for our products. Should orders and market conditions differ significantly from our estimates, our future results of operations could be materially adversely affected. In the future, we may be required to record write-downs of finished products and materials on-hand and/or additional charges for excess purchase commitments as a result of future changes in our sales forecasts or customer orders.

​

Due to the volatile and flammable nature of certain components of our products and equipment, fires or explosions may disrupt our business or cause significant injuries, which could adversely affect our financial results.

​

The development and manufacture of certain of our products involves the handling of a variety of explosive and flammable materials as well as high power equipment. From time to time, these activities may result in incidents that could cause us to temporarily shut down or otherwise disrupt some manufacturing processes, causing production delays and resulting in liability for workplace injuries and/or fatalities. We have safety and loss prevention programs that

34

Table of Contents

require detailed reviews of process changes and new operations, along with routine safety audits of operations involving explosive materials, to mitigate such incidents, as well as a variety of insurance policies, however our insurance coverage may be inadequate to cover all claims and losses related to such incidents. We may experience such incidents in the future, which could result in production delays or otherwise have a material adverse effect on our business and financial condition.

​

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

​

Urban environments may present certain challenges to the operators of UAS. UAS 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 UAS in general. As the usage of UAS has increased, particularly by military customers, the danger of such collisions has increased. Furthermore, the incorporation of our DDL technology into our small UAS has increased the number of vehicles which can operate simultaneously in a given area and with this increase has come an increase in the risk of accidental collision. 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 UAS in urban environments may limit their value in such environments, which may limit demand for our UAS 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:

​

| ● | fluctuations in revenue derived from government contracts, including cost-plus-fee contracts and contracts with a performance-based fee structure;

​

| ● | the size and timing of orders from military and other governmental agencies, including increased purchase requests from government customers for equipment and materials in connection with the U.S. government’s fiscal year end, which may affect our quarterly operating results;

​

| ● | the mix of products and services that we sell in the period;

​

| ● | fluctuations in customer demand for some of our products or services;

​

| ● | unanticipated costs incurred in the introduction of new products and services;

​

| ● | fluctuations in the adoption of our products and services in new markets;

​

| ● | our ability to win additional contracts from existing customers or other contracts from new customers;

​

| ● | cancellations, delays or contract amendments by our U.S. governmental agency and foreign government customers;

​

| ● | changes in policy or budgetary measures that adversely affect our U.S. governmental agency and foreign government customers;

​

| ● | the cost of complying with various regulatory requirements applicable to our business and the potential penalties or sanctions that could be imposed for non-compliance; and

​

| ● | our ability to obtain the necessary export licenses for sales of our products and services to international customers.

​

35

Table of Contents

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 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 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. To the extent that these external sources of funding 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.

​

Our work for the U.S. government and international governments may expose us to security risks.

​

As a U.S. government contractor, we face various security threats, including cyber security attacks on our information technology infrastructure, attempts to gain access to our proprietary, financial, banking or classified information as well as threats to the physical security of our facilities and employees. Although we utilize various procedures and controls to monitor and mitigate these threats, there can be no assurance that these procedures and controls will be sufficient to prevent disruptions, the unauthorized release of confidential technical, financial or banking information or corruption of data. Accordingly, any significant operational delays, or any destruction, manipulation or improper use of our data, information systems or networks could adversely affect our financial results and damage the reputation for our products and services. The occurrence of some of these risks may be increased due to the increase in remote working by our employees, suppliers, contractors and other third parties due to the COVID-19 pandemic. Due to the ever developing nature of such risks, the impact of any potential incident cannot be predicted. Previous cyber-attacks directed at us have not materially impacted our business or financial results, but the impact of future incidents cannot be predicted due to the evolving nature and complexity of cyber-attacks. If we or our partners are subject to data security breaches, we may have a loss in sales or increased costs arising from the restoration or implementation of additional security measures, either of which could materially and adversely affect our business and financial results. Additionally, expenses resulting from cyber security attacks and other security risks may not be fully insured or otherwise mitigated, which could harm our financial results.

​

In addition, 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 or adjacent to high-risk locations, such as Iraq and Afghanistan, where the country or location is experiencing political, social or economic issues, or war or civil unrest. 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 be negatively impacted by the loss of employees and contractors, which could harm our business and operating results.

​

Our cash may be subject to a risk of loss and we may be exposed to fluctuations in the market values of our portfolio investments and in interest rates.

​

Our assets include a significant amount of cash and investments. We adhere to an investment policy set by our Board of Directors which aims to preserve our financial assets, maintain adequate liquidity and maximize returns. We believe that our cash is held in institutions whose credit risk is minimal and that the value and liquidity of our deposits are accurately reflected in our consolidated financial statements as of April 30, 2021. We currently invest the majority of our cash in U.S. government securities, U.S. government agency securities, municipal bonds and high-grade corporate

36

Table of Contents

bonds, the performance of which are subject to additional market risks related to their respective issuers. Nearly all of our cash and bank deposits are not insured by the Federal Deposit Insurance Corporation. Therefore, our cash and any bank deposits that we now hold or may acquire in the future may be subject to risks, including the risk of loss or of reduced value or liquidity. Our investments are classified as available-for-sale and recorded at fair value each reporting period. Unrealized gains and losses are excluded from earnings and reported as a separate component of stockholders’ equity, net of deferred income taxes.

​

Unstable market and economic conditions may have serious adverse consequences on our business, financial condition and stock price.

​

Global credit and financial markets have experienced extreme disruptions in recent years, including severely diminished liquidity and credit availability, declines in consumer confidence, declines in economic growth, increases in unemployment rates and uncertainty about economic stability. There can be no assurance that renewed deterioration in credit and financial markets and confidence in economic conditions will not occur. Our general business strategy may be adversely affected by any economic downturn, volatile business environment or continued unpredictable and unstable market conditions. If the current equity and credit markets deteriorate, or do not improve, it may make any necessary debt or equity financing more difficult, costlier and more dilutive. Failure to secure any necessary financing in a timely manner and on favorable terms could have a material adverse effect on our growth strategy, financial performance and stock price and could require us to delay or abandon implementing business initiatives. These events and the continuing market upheavals could adversely affect our business in a number of ways, including:

​

Potential Deferment of Purchases and Orders by Customers: Uncertainty about current and future global economic conditions may cause governments, including the U.S. government, which is our largest customer, consumers and businesses to modify, defer or cancel purchases in response to tighter credit, decreased cash availability and declining consumer confidence. Accordingly, future demand for our products could differ materially from our current expectations. Additionally, if customers are not successful in generating sufficient revenue or are precluded from securing financing, they may not be able to pay, or may delay payment of, accounts receivable that are owed to us. Any inability of current and/or potential customers to pay us for our products may adversely affect our earnings and cash flow.

​

Negative Impact from Increased Financial Pressures on Key Suppliers: Our ability to meet customers’ demands depends, in part, on our ability to obtain timely and adequate delivery of quality materials, parts and components from our suppliers. Certain of our hardware components and various subsystems are available only from a limited group of suppliers. If certain key suppliers were to become capacity constrained or insolvent as a result of a market downturn, then we may have to find new 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. In addition, credit constraints of key suppliers could result in accelerated payment of accounts payable by us, impacting our cash flow.

​

Customers’ Inability to Obtain Financing to Make Purchases from Us and/or Maintain Their Business: Some of our customers may require substantial financing in order to fund their operations and make purchases from us. The inability of these customers to obtain sufficient credit to finance purchases of our products, or otherwise meet their payment obligations to us could adversely impact our financial condition and results of operations. In addition, if a market downturn results in insolvencies for our customers, it could adversely impact our financial condition and results of operations.

​

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

​

In June 2019, we consummated the acquisition of Pulse Aerospace, LLC. In February 2021 we completed the acquisition of Arcturus and ISG, and in May 2021 we acquired Telerob. We intend to consider additional acquisitions that could add to our customer base, technological capabilities or system offerings. Acquisitions, including our recent

37

Table of Contents

acquisitions of Arcturus, ISG and Telerob, involve numerous risks, any of which could harm our business, including the following:

​

| ● | difficulties in integrating the operations, technologies, products, existing contracts, accounting and personnel of each target company and realizing the anticipated synergies of the combined businesses;

​

| ● | difficulties in supporting and transitioning customers, if any, of each target company;

​

| ● | diversion of financial and management resources from existing operations;

​

| ● | the price we pay or other resources that we devote may exceed the value we realize, or the value we could have realized if we had allocated the purchase price or other resources to another opportunity; ​

| ● | risks of entering new markets in which we have limited or no experience the complexities of managing a workforce under foreign labor and employment law and related organizational requirements;

​

| ● | potential loss of key employees, customers and strategic alliances from either our current business or the target company’s business;

​

| ● | assumption of unanticipated problems or latent liabilities, such as problems with the quality of the target company’s products or its regulatory compliance; ​

| ● | expanded regulatory compliance complexity and risk; and

​

| ● | inability to generate sufficient revenue to offset acquisition costs.

​

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, such as the stock issued as consideration for the purchase of Arcturus, then our existing stockholders may be diluted, which could lower the market price of our common stock. If we finance acquisitions through debt, such as the credit facilities we entered into in connection with the consummation of our acquisition of Arcturus, then such future debt financing may contain covenants or other provisions that limit our operational or financial flexibility.

​

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.

​

Borrowings under our credit facilities could adversely affect our financial condition and restrict our operating flexibility.

​

On February 19, 2021, in connection with the consummation of the Arcturus acquisition, we entered into a credit agreement with certain lenders, letter of credit issuers, and others (the “Credit Agreement”), which, together with its associated Security and Pledge Agreement, sets forth the terms and conditions of a five-year $100 million revolving credit facility, which includes a $10 million sublimit for the issuance of standby and commercial letters of credit (the “Revolving Facility”), and a five-year amortized $200 million term A loan (the “Term Loan Facility”, and together with the Revolving Facility, the “Credit Facilities”). Upon execution of the Credit Agreement, we drew down $200.0 million, the full principal amount of the Term Loan Facility, to partially finance the acquisition of Arcturus.

​

The Term Loan Facility has a five-year term expiring in February 2026 and bears interest, at our option, either at a LIBOR rate or a base rate plus a fixed applicable margin dependent on our consolidated leverage ratio under the terms of the agreement. We are required to pay 5.0% of the outstanding obligations under the Term Loan Facility in each of the first four loan years, with the remaining 80.0% payable in the fifth loan year, consisting of three quarterly

38

Table of Contents

payments of 1.25% each, with the remaining outstanding principal amount of the Term Loan Facility due and payable on the maturity date. The Revolving Facility has a term of 5 years. As of April 30, 2021 we have only letters of credit issued pursuant to the Revolving Facility, totaling $5.0 million.

​

In support of our obligations under the Credit Facilities, we have granted security interests in substantially all of our personal property and that of our domestic subsidiaries, including a pledge of the equity interests in our subsidiaries (limited to 65% of outstanding equity interests in the case of our foreign subsidiaries), subject to customary exclusions and exceptions. In addition, our domestic subsidiaries, including Arcturus, are required to be guarantors of the Credit Facilities.

​

In addition, our increased level of indebtedness may have important consequences to us, including:

​

| ● | increasing our vulnerability to adverse general economic and industry conditions;

​

| ● | requiring us to dedicate a portion of our cash flows to the payment of interest and when applicable, principal, on our indebtedness and other obligations thereby reducing the availability of our cash flow to fund working capital, capital expenditures, research and development efforts, execution of our business strategy, acquisitions and other general corporate purposes;

​

| ● | limiting our flexibility in planning for, or reacting to, changes in the economy, the defense industry, and the markets in which we operate; ​

| ● | subjecting us to maintenance of various financial covenants and adherence to certain other affirmative and negative covenants, requiring us to seek lender consent or waiver in relation to our financial performance or other potential strategic actions in the future; ​

| ● | placing us at a competitive disadvantage compared to our competitors with less indebtedness; ​

| ● | exposing us to substantial interest rate risk due to the variable interest rate under the Credit Facilities, such that, if interest rates were to increase substantially during the term of the Credit Facilities, the resulting increase in our interest payment obligations could adversely affect our operating results and our ability to service the indebtedness under the Credit Facilities; and ​

| ● | making it more difficult for us to borrow additional funds in the future to fund our growth, acquisitions, working capital, capital expenditures, and other purposes.

​

To the extent we incur additional indebtedness, the risks described above could increase.

​

If we do not have sufficient funds to repay the Term Loan Facility when it becomes due in 2026, it may be necessary to refinance our debt through additional debt or equity financings. If, at the time of any such refinancing, prevailing interest rates or other factors result in higher interest rates on such refinanced debt, such increases in our interest expense could have an adverse effect on our business, results of operations and financial condition.

​

The Credit Agreement contains customary events of default, upon the occurrence and during the continuation of which, after any applicable grace period, the lenders would have the ability to declare the loans due and payable in whole or in part. Among other things, if we fail to make required debt payments, or if we fail to comply with financial or other covenants in the Credit Agreement, we would be in default under the terms thereof. The Credit Agreement contains customary negative covenants that include, subject to customary exclusions:

​

| ● | Restrictions on additional liens on our assets.

| ● | Restrictions on incurring additional indebtedness.

| ● | Restrictions on new investments, including acquisitions, mergers, investments in subsidiaries that are not guarantors of the debt, and joint ventures.

| ● | Restrictions on disposal of assets.

39

Table of Contents

| ● | Restrictions on payments of cash dividends.

| ● | Restrictions on changing the nature of our business.

| ● | A requirement to maintain a maximum consolidated leverage ratio and a minimum fixed charge coverage ratio.

| ● | Restrictions on changes to our accounting policies.

| ● | Restrictions on payments of any junior indebtedness.

​

To the extent we would wish to engage in any of the prohibited behaviors, we would need to obtain consent under the Credit Agreement, which may not be timely forthcoming or at all. If a default event were to occur, we may not have sufficient available cash to repay such outstanding debt obligations at the time they become due, or be able to refinance such debt on acceptable terms or at all.

​

Any of the foregoing limitations or events could materially and adversely affect our financial condition and results of operations.

​

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

​

The majority of our research and development and manufacturing operations are located in California, regions 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.

​

We face various risks related to the COVID-19 novel coronavirus pandemic and similar public health crises which may adversely impact our business.

​

In December 2019, a novel strain of a virus named SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2), or coronavirus, which causes coronavirus disease, or COVID-19, was reported to have surfaced in Wuhan, China, and has reached multiple other regions and countries, including the United States and, more specifically, Southern California, where our primary operations are located. The coronavirus pandemic is evolving, and to date has led to the implementation of various responses, including government-imposed stay-at-home orders and quarantines, travel restrictions and other public health safety measures. Although our operations have mostly continued uninterrupted during the COVID-19 outbreak, adoption of work from home protocols, social distancing measures in the workplace and other responsive actions have required certain changes to our operations. Despite an increase in vaccinations in the United States, vaccinations have adopted more slowly internationally, and if the current COVID-19 pandemic continues and results in additional periods of travel and other similar logistics restrictions, this may further reduce our and our customers’ capabilities to travel, domestically and internationally, which may impact our ability to perform certain contracts, develop and renew contracts, or market our products, or could otherwise disrupt portions of our business and have a material adverse effect on our results of operations.

​

Global health concerns, such as coronavirus, could result in social, economic and labor instability in the countries in which we or the third parties with whom we engage operate. It is not currently possible to ascertain the overall impact of the COVID-19 outbreak, if any, on our business. The extent to which COVID-19 impacts on our business, financial condition and results of operations and those of our third party partners will depend on future developments as to the geographic presence of COVID-19, rates of vaccination, government and healthcare responses to such spread including the duration of the outbreak, new information that may emerge concerning the severity of the coronavirus and the actions to contain the coronavirus or treat its impact, among others, which remain highly uncertain. We cannot presently predict the scope and severity of any potential business disruptions, but if we or any of the third parties with whom we engage, including suppliers and other third parties with whom we conduct business, were to experience prolonged shutdowns or other business disruptions, including a slowdown in the effectiveness of our workforce due to illness or otherwise, our ability to conduct our business in the manner presently planned could be materially and negatively impacted. The COVID-19 outbreak has caused delays in the timing of our customers’ awarding of contracts to us, and while such delays have not yet had a significant impact on our business, there can be no assurances that any such delays would not have a material adverse impact on our business and results of operations in the future. The COVID-19 pandemic could also cause delays or limits in the ability of our customers to make timely payments to us. Additionally, our government customers may have more limited resources available to purchase our

40

Table of Contents

products due to deteriorating economic conditions or due to the diversion of resources to other budget priorities, including efforts to address the COVID-19 pandemic. The future progression of the COVID-19 outbreak and its resulting effects on our business, financial condition and results of operations are uncertain and are continuing to be assessed.

​

We self-insure a portion of our health insurance program which may expose us to unexpected costs and negatively affect our results of operations.

​

We are self-insured for the majority of our employee medical claims, subject to individual and aggregate stop loss insurance policies. We estimate a liability for claims filed and incurred but not reported 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. However, unanticipated changes in assumptions and management estimates underlying our recorded liabilities for medical claims could result in materially different amounts of expense than expected under our health insurance program, which could have an adverse material impact on our financial condition and results of operations.

​

Risks Related to Our U.S. Government Contracts

​

We are presently classified as a small business defense contractor and the loss of our small business status may adversely affect our ability to compete for small business set-aside US government contracts.

​

Because we have fewer than 1,500 employees, we are presently classified as a small business defense contractor under our primary North American Industry Classification Systems (“NAICS”) industry and product specific codes (336411 - Aircraft Manufacturing) which are regulated in the United States by the Small Business Administration (“SBA”). Businesses that meet the small business size standard for the relevant NAICS code are able to bid on small business set-aside contracts. While we do not presently derive a substantial portion of our business from contracts which are set-aside for small businesses, we are able to bid on small business set-aside contracts as well as contracts which are open to non-small business entities. As we continue to grow and add employees, including through acquisitions, or if NAICS codes are revised, we could cease to qualify as a small business, which could adversely impact our eligibility for special small business programs and limit our ability to partner with other business entities that seek to team with small business entities as may be required under a specific contract. If we outgrow our small business classification, we would not be eligible to serve as the prime contractor on small business set aside programs and may need to implement a small business subcontracting plan with other companies that qualify as a small business, for SBA approval. The loss of our small business classification could have a material adverse effect on our financial position and/or results of operations. Additionally, if we are no longer eligible for the small business exemption from compliance with the full range of Cost Accounting Standards (“CAS”), we would be required to demonstrate compliance with such standards upon the award of a contract subject to the full range of CAS, which will impose additional administrative costs on our business, and may significantly affect the manner in which we conduct our business with our customers and adversely affect our results of operations.

​

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:

​

| ● | the Federal Acquisition Regulations and supplemental agency regulations, which comprehensively regulate the formation and administration of, and performance under, U.S. government contracts;

​

| ● | the Truth in Negotiations Act, which requires certification and disclosure of all factual cost and pricing data in connection with contract negotiations;

​

41

Table of Contents

| ● | the False Claims Act and the False Statements Act, which impose penalties for payments made on the basis of false facts provided to the government and on the basis of false statements made to the government, respectively;

​

| ● | the Foreign Corrupt Practices Act, which prohibits U.S. companies from providing anything of value to a foreign official to help obtain, retain or direct business, or obtain any unfair advantage;

​

| ● | the National Telecommunications and Information Administration and the Federal Communications Commission, which regulate the wireless spectrum allocations upon which UAS depend for operation and data transmission in the United States;

​

| ● | the Federal Aviation Administration, which regulates the use of airspace for all aircraft, including UAS operation in the United States;

​

| ● | the International Traffic in Arms Regulations, which regulate the export of controlled technical data, defense articles and defense services and restrict from which countries we may purchase materials and services used in the production of certain of our products; and

​

| ● | laws, regulations and executive orders restricting the use and dissemination of information classified for national security purposes or determined to be “controlled unclassified information” and the exportation of certain products and technical data.

​

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 and facilities to obtain government security clearances. Our failure to comply with applicable regulations, rules and approvals; changes in the government’s interpretation of such regulations, rules and approvals as have been and are applied to our contracts, proposals or business or misconduct by any of our employees could result in the imposition of fines and penalties, the loss of security clearances, a decrease in profitability, the loss of our government contracts or our suspension or debarment from contracting with the U.S. government generally, any of which could 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 or investigation by the U.S. government.

​

U.S. government agencies, primarily the DCAA and the DCMA, 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, quality, accounting, property, estimating, compensation and management information systems.

​

Like most government contractors, our contracts are audited and reviewed on a continual basis by the DCMA and the DCAA. The indirect costs we incur in performing government contracts have been audited or have been subject to audit on an annual basis. The audit of our 2010 incurred cost claim was settled in April 2016 without payment of any consideration. Our incurred cost claims for fiscal years 2011 through 2014 were accepted as submitted during the fiscal year ended April 30, 2017. Our 2016 and 2017 rates claims were accepted without audit during the fiscal year ended April 30, 2019 without payment of any consideration. During the fiscal year ended April 30, 2020, the Company settled rates for its incurred cost claims with the DCAA for fiscal year 2015 for an amount that was not significant. At April 30, 2021 we had no reserve for open incurred cost claim audits. In addition, non-audit reviews or investigations by the government may still be conducted on all of our government contracts.

​

42

Table of Contents

Any costs found to be improperly allocated to a specific cost reimbursement contract will not be reimbursed, while such costs already reimbursed must be refunded. If an audit or investigation 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, suspension of payments, fines and suspension or debarment from doing business with the U.S. government. We could experience serious harm to our reputation if allegations of impropriety or illegal acts were made against us, even if the allegations were inaccurate. In addition, responding to governmental audits or investigations may involve significant expense and divert management attention. If any of the foregoing were to occur, our financial condition and operating results could be materially adversely affected.

​

Moreover, if any of our administrative processes and business systems are found not to comply with the applicable requirements, we may be subjected to increased government scrutiny or required to obtain additional governmental approvals that could delay or otherwise adversely affect our ability to compete for or perform contracts. In December 2015, DCMA concluded that our purchasing system was not approved. In an April 2016 follow-up review the DCMA approved our purchasing system. The purchasing systems was reviewed and approved again in January 2019. An unfavorable outcome to such an audit or investigation by the DCAA, U.S. Department of Justice (“DOJ”), or other government agency, could materially adversely affect our competitive position, affect our ability to obtain new government business, and obtain the maximum price for our products and services, and result in a substantial reduction of our revenues.

​

If we were suspended or debarred from contracting with the federal government generally, or any specific agency, if our reputation or relationship with government agencies were impaired, or if the government otherwise ceased doing business with us or significantly decreased the amount of business it does with us, our revenue and operating results could be materially harmed. For example, in February 2010, we were notified by the DOJ that it had initiated a civil investigation into our cost charging practices with respect to government contracts. We resolved these claims with the DOJ in October 2013. Under the settlement agreement, we reimbursed the government for an amount erroneously charged to the government in our fiscal 2006 incurred cost claim submittal.

​

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 that data is 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.

​

U.S. government 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.

​

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

43

Table of Contents

government contracts could have a negative impact on our results of operations and financial condition. Termination arising out of our default could result in damage to our reputation, 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 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:

​

| ● | the need to bid on programs in advance of the completion of their design, which may result in unforeseen technological difficulties and cost overruns;

​

| ● | the substantial cost and managerial time and effort that must be spent to prepare bids and proposals for contracts that may not be awarded to us;

​

| ● | the need to estimate accurately the resources and cost structure that will be required to service any contract we are awarded; and

​

| ● | the expense and delay that may arise if our competitors protest or challenge contract awards made to us pursuant to competitive bidding, and the risk that any such protest or challenge could result in the delay of our contract performance, the distraction of management, the resubmission of bids on modified specifications, or in termination, reduction or modification of the awarded contract.

​

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 for a number of years in the market for goods and services that are provided under those contracts. If we are unable to win new contract awards over any extended period consistently, then our business and prospects will be adversely affected.

​

We are subject to procurement rules and regulations, which increase our performance and compliance costs under our U.S. government contracts.

​

We must comply with, and are affected by, laws and regulations relating to the formation, administration and performance of U.S. government contracts. These laws and regulations, among other things, require certification and disclosure of all cost and pricing data in connection with contract negotiation, define allowable and unallowable costs and otherwise govern our right to reimbursement under certain cost-based U.S. government contracts, and restrict the use and dissemination of classified information and the exportation of certain products and technical data. These requirements, although customary in U.S. government contracts, increase our performance and compliance costs. These costs might increase in the future, reducing our margins, which could have a negative effect on our financial condition. Although we believe we have procedures in place to comply with these regulations and requirements, the regulations and requirements are complex and change frequently. Our or our agents’ failure to comply with these regulations and requirements under certain circumstances could lead to suspension or debarment from U.S. government contracting or subcontracting for a period of time and could have a negative effect on our reputation and ability to receive other U.S. government contract awards in the future.

Risks Related to Legal and Regulatory Requirements

​

We could be prohibited from shipping our products to certain countries if we are unable to obtain U.S. government authorization regarding the export of our products, or if current or future export laws limit or otherwise restrict our business. In addition, failure to comply with export laws could result in fines, export restrictions and other sanctions and penalties.

​

We must comply with U.S. and other laws regulating the export of our products. In some cases, explicit authorization from the relevant U.S. government authorities is needed to export our products. The export regulations and the governing policies applicable to our business are subject to change. We cannot provide assurance that such export authorizations will be available for our products in the future. Compliance with these laws has not significantly limited our operations or our sales in the recent past, but could significantly limit them in the future. We maintain an export compliance program but there are risks that our compliance controls may be ineffective. In November 2019, we entered into a consent agreement (the “Consent Agreement”) with the U.S. Department of State’s Directorate of Defense Trade Controls Office of Defense Trade Controls Compliance to resolve various alleged violations of the Armed Export Control Act and the International Traffic in Arms Regulations (“ITAR”) that occurred between June 2014 and December 2016. The Consent Agreement has a two-year term and provides for, among other things: (i) a civil penalty of $1,000,000 payable in installments, $500,000 of which was suspended on the condition that such amount be used future remedial compliance costs over the term of the Consent Agreement and/or credited against prior compliance enhancement costs already expended by us; (ii) the appointment of an external Special Compliance Officer for a minimum of one year to oversee our compliance with the Consent Agreement and ITAR; and (iii) one external audit of our compliance with the Consent Agreement and ITAR. The $500,000 suspension amount was satisfied by our compliance program remediation efforts during our fiscal year ended April 30, 2021. Our failure to comply with the terms of the Consent Agreement or export laws and regulations in general can subject us to additional fines, penalties and sanctions, including suspension of export privileges, which could have a material adverse impact on our business, operations and financial condition and limit or prevent us from being able to sell our products in certain international jurisdictions.

​

Failure to obtain necessary regulatory approvals from the FAA or other governmental agencies, or limitations put on the use of small and medium UAS in response to public privacy concerns, may prevent us from expanding the sales of our small and medium UAS to non-military customers in the United States.

​

The regulation of small and medium UAS for commercial use in the United States is undergoing substantial change and the ultimate treatment is uncertain. In 2006, the FAA issued a clarification of its existing policies stating that, in order to engage in commercial use of small and medium UAS in the U.S. National Airspace System, a public operator must obtain a COA from the FAA, or fly in restricted airspace. The FAA’s COA approval process requires that the public operator certify the airworthiness of the aircraft for its intended purpose, that a collision with another aircraft or other airspace user is extremely improbable, that the small unmanned aircraft system complies with appropriate cloud and terrain clearances and that the operator or spotter of the small unmanned aircraft system is generally within one half-mile laterally and 400 feet vertically of the small unmanned aircraft system while in operation. Furthermore, the FAA’s clarification of existing policy stated that the rules for radio-controlled hobby aircraft do not apply to public or commercial use of small and medium UAS.

​

On February 14, 2012, the FAA Modernization and Reform Act of 2012 was enacted, establishing various deadlines for the FAA to allow expanded use of small and medium UAS for both public and commercial applications. On June 21, 2016, the FAA released its final rules regarding the routine use of certain small UAS (under 55 pounds) in the U.S. National Airspace System pursuant to the act (the “Part 107 Rules”). The Part 107 Rules, which became effective in August 2016, provided safety regulations for small UAS conducting non-recreational operations and contain various limitations and restrictions for such operations, including a requirement that operators keep UAS within visual-line-of-sight and prohibiting flights over unprotected people on the ground who are not directly participating in the operation of the UAS. Additionally, in December 2019 and January 2020, the FAA proposed rules regarding remote UAS identification and a new policy regarding the airworthiness certification of a newly created special class of UAS. It is unclear when, if ever, the FAA will implement any final rules regarding remote UAS identification and whether such final rules will differ from the proposed rules or when, if ever, the FAA will create a new class of UAS and what the

45

Table of Contents

final rules regarding the certification of such new class of UAS will state. We cannot assure you that the Part 107 Rules, or any final rules enacted in furtherance on the FAA’s recently announced proposals, will result in the expanded use of our small and medium UAS by law enforcement or other non-military government agencies or commercial entities and we may not be able to expand our sales of small and medium UAS beyond our military customers, which could harm our business prospects.

​

In addition, there exists public concern regarding the privacy implications of U.S. commercial and law enforcement use of small UAS. This concern has included calls to develop explicit written policies and procedures establishing usage limitations. We cannot assure you that the response from regulatory agencies, customers and privacy advocates to these concerns will not delay or restrict the adoption of small and medium UAS by non-military customers.

​

Our business may be dependent upon our employees obtaining and maintaining required security clearances, as well as our ability to obtain security clearances for the facilities in which we perform sensitive government work.

​

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.

​

As a manufacturer of commercial UAS, we are subject to various government regulations and may be subject to additional regulations in the future, violation of which could subject us to sanctions or otherwise harm our business.

​

As a manufacturer of consumer products, we are subject to significant government regulations, including, in the United States, those issued under the Consumer Products Safety Act, as well as those issued under product safety and consumer protection statutes in our international markets. Failure to comply with any applicable product safety or consumer protection regulation could result in sanctions that could have a negative impact on our business, financial condition and results of operations.

​

Governments and regulatory agencies in the markets where we manufacture and sell products may enact additional regulations relating to product safety and consumer protection in the future, and may also increase the penalties for failure to comply with product safety and consumer protection regulations. In addition, one or more of our customers might require changes in our products, such as the non-use of certain materials, in the future. Complying with any such additional regulations or requirements could impose increased costs on our business. Similarly, increased penalties for non-compliance could subject us to greater expenses in the event any of our products were found to not comply with such regulations. Such increased costs or penalties could harm our business.

​

We could be the subject of future product liability suits or product recalls, which could harm our business.

​

We may be subject to involuntary product recalls or may voluntarily conduct a product recall. The costs associated with any future product recalls could be significant. In addition, any product recall, regardless of direct costs of the recall, may harm consumer perceptions of our products and have a negative impact on our future revenues and results of operations. Subject to a determination of the appropriateness of any recall, we remain responsible for the non-warranty costs from the recall of completed products we manufactured, sold or serviced prior to closing of the sale of substantially all of the assets and related liabilities of our EES Business to Webasto, pursuant to an Asset Purchase Agreement (the “Purchase Agreement”). In particular, on August 24, 2018, Webasto filed a recall report with the National Highway Traffic Safety Administration (“NHTSA”) that named us as a brand of the affected equipment. To the extent we are obligated under the terms of the Purchase Agreement with Webasto or as a result of the lawsuit filed by

46

Table of Contents

Webasto against us seeking costs related to the recall or pursuant to applicable law for all or any portion of the costs incurred in connection with such recall, or any other such recall, our results of operations may be negatively affected.

​

In addition to government regulation, products that have been or may be developed by us may expose us to potential liability from personal injury or property damage claims by the users of such products. There can be no assurance that a claim will not be brought against us in the future, regardless of merit. While we maintain insurance coverage for product liability claims, our insurance may be inadequate to cover any such claims. Any successful claim could significantly harm our business, financial condition and results of operations.

​

We are subject to pending legal proceedings that may disrupt our business, cause us to incur substantial costs, expose us to significant legal liabilities and could have a material adverse impact on our financial performance.

​

We are subject to various legal proceedings and claims, including a lawsuit filed by Webasto alleging several claims against us arising out of or related to our sale of our EES Business to Webasto in June 2018 and the NHTSA recall. Additional lawsuits may arise in the future. Occasionally we are also involved in governmental inquiries and investigations and administrative and regulatory proceedings. Our activities relating to defending and responding to any such proceedings may result in substantial legal expenses, may disrupt our sales and marketing or other business activities, including our relationships with our customers, suppliers, employees and other third parties, and divert management’s and our employees’ attention from our day-to-day operations, which may have an adverse impact on our financial performance. The results of any such proceedings are unpredictable. We record accruals for liabilities where we believe a loss is probable and reasonably estimable, however, our actual losses may differ significantly from our estimates. As a result of an offer of settlement we made to Webasto in the pending litigation to avoid the future cost, expense and distraction of the litigation, we were required to record a litigation reserve related to the litigation, although such offer does not reflect our view of the merits of the claims made in the litigation. An adverse or unfavorable resolution of any proceedings against us, including the litigation with Webasto, could have a material impact on our financial position, cash flows and results of operations.

​

Our business is subject to federal, state and international laws regarding data protection, privacy, and information security, as well as confidentiality obligations under various agreements, and our actual or perceived failure to comply with such obligations could damage our reputation, expose us to litigation risk and adversely affect our business and operating results.

​

In connection with our business, we receive, collect, process and retain certain sensitive and confidential customer information. As a result, we are subject to increasingly rigorous federal, state and international laws regarding privacy and data protection. Personal privacy, data protection and information security are significant issues in the United States and the other jurisdictions where we offer our products and services. The regulatory framework for privacy and security issues worldwide is rapidly evolving and is likely to remain uncertain for the foreseeable future. Our handling of data is subject to a variety of laws and regulations, including regulation by various government agencies, including the United States Federal Trade Commission (“FTC”) and various state, local and foreign bodies and agencies. We also execute confidentiality agreements with various parties under which we are required to protect their confidential information.

​

The United States federal and various state and foreign governments have adopted or proposed limitations on the collection, distribution, use and storage of personal information of individuals, including end-customers and employees. In the United States, the FTC and many state attorneys general are applying federal and state consumer protection laws to the online collection, use and dissemination of data. Additionally, many foreign countries and governmental bodies, and other jurisdictions in which we operate or conduct our business, have laws and regulations concerning the collection and use of personal information obtained from their residents or by businesses operating within their jurisdiction. These laws and regulations often are more restrictive than those in the United States. Such laws and regulations may require companies to implement new privacy and security policies, permit individuals to access, correct and delete personal information stored or maintained by such companies, inform individuals of security breaches that affect their personal information, and, in some cases, obtain individuals’ consent to use personal information for certain purposes.

​

47

Table of Contents

We also expect that there will continue to be new proposed laws, regulations and industry standards concerning privacy, data protection and information security in the United States, the European Union and other jurisdictions, and we cannot yet determine the impact of such future laws, regulations and standards may have on our business. For example, the California Consumer Privacy Act, which became effective in 2020, provides new data privacy rights for consumers and new operational requirements for companies. Additionally, we expect that existing laws, regulations and standards may be interpreted differently in the future. There remains significant uncertainty surrounding the regulatory framework for the future of personal data transfers from the European Union to the United States with regulations such as the recently adopted General Data Protection Regulation (“GDPR”), which imposes more stringent E.U. data protection requirements, provides an enforcement authority, and imposes large penalties for noncompliance. Future laws, regulations, standards and other obligations, including the adoption of the GDPR, as well as changes in the interpretation of existing laws, regulations, standards and other obligations could impair our ability to collect, use or disclose information relating to individuals, which could decrease demand for our products, require us to restrict our business operations, increase our costs and impair our ability to maintain and grow our customer base and increase our revenue.

​

Although we are working to comply with those federal, state and foreign laws and regulations, industry standards, contractual obligations and other legal obligations that apply to us, such laws, regulations, standards and obligations are evolving and may be modified, interpreted and applied in an inconsistent manner from one jurisdiction to another, and may conflict with one another, other requirements or legal obligations, our practices or the features of our products. As such, we cannot assure ongoing compliance with all such laws or regulations, industry standards, contractual obligations and other legal obligations, and our efforts to do so may cause us to incur significant costs or require changes to our business practices, which could adversely affect our business and operating results. Any failure or perceived failure by us to comply with federal, state or foreign laws or regulations, industry standards, contractual obligations or other legal obligations, or any actual or suspected security incident, whether or not resulting in unauthorized access to, or acquisition, release or transfer of personal information or other data, may result in governmental enforcement actions and prosecutions, private litigation, fines and penalties or adverse publicity and could cause our customers to lose trust in us, which could have an adverse effect on our reputation and business. Any inability to adequately address privacy and security concerns, even if unfounded, or comply with applicable laws, regulations, policies, industry standards, contractual obligations or other legal obligations could result in additional cost and liability to us, damage our reputation, inhibit sales, and adversely affect our business and operating 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. Given the increasing focus on environmental compliance by regulators and the general public, any incidence of non-compliance could result in damage to our reputation beyond the fines and other sanctions that could be imposed. 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 later 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 never 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.

​

Compliance with the SEC’s conflict minerals regulations may increase our costs and adversely impact the supply-chain for our UAS products.

​

In August 2012, the SEC adopted disclosure rules regarding a company’s use of conflict minerals in its products with substantial supply chain verification requirements in the event that the conflict minerals come from, or

48

Table of Contents

could have come from, the Democratic Republic of the Congo or adjoining countries. These rules and verification requirements have imposed additional costs on us and on our suppliers, including costs related to determining the source of conflict minerals used in our products, which may adversely affect our results of operations. We are dependent on information supplied by our first tier suppliers in conducting due diligence into the origins of conflict minerals in our products and in complying with our SEC reporting obligations. To the extent that information we receive from our suppliers is inaccurate or inadequate, we may not be able to determine whether our products are conflict mineral-free. We may face challenges in satisfying our customers who may require that our products be certified as conflict mineral-free, which could place us at a competitive disadvantage and could harm our business. These regulations could also have the effect of limiting the pool of suppliers from which we source items containing conflict minerals, and we may be unable to obtain conflict-free minerals at competitive prices, if at all, which could increase our costs and adversely affect our results of operations.

​

Risks Related to Our Intellectual Property

​

If we fail to protect, or incur significant costs in defending or enforcing our intellectual property and other proprietary rights, our business, financial condition 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. In addition, the U.S. government has licenses under certain of our patents and certain other intellectual property that are developed or used in performance of government contracts, and it may use or authorize others to use such patents and intellectual property for government and other purposes. 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 our rights may be challenged by third parties. The laws of countries other than the United States may be even less protective of our 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 our employment 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. From time to time, we have initiated lawsuits to protect our intellectual property and other proprietary rights. Pursuing these claims is time consuming and expensive and could adversely impact our results of operations.

​

In addition, affirmatively defending our intellectual property rights and investigating whether any of our products or services violate the rights of others may entail significant expense. 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. Defending against, or otherwise addressing, any such claims, whether they are 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 from the third party asserting the claim a license on commercially reasonable terms, if at all; develop alternative technology on a timely basis, if at all;

49

Table of Contents

or 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

​

The price of our common stock may fluctuate significantly.

​

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:

​

| ● | U.S. government spending levels, both generally and by our particular customers;

​

| ● | the volume of operational activity by the U.S. military;

​

| ● | delays in the payment of our invoices by government payment offices, resulting in potentially reduced earnings during a particular fiscal quarter;

​

| ● | announcements of new products or technologies, commercial relationships or other events relating to us or our industry or our competitors;

​

| ● | failure of any of our key products to gain market acceptance;

​

| ● | variations in our quarterly operating results;

​

| ● | perceptions of the prospects for the markets in which we compete;

​

| ● | changes in general economic conditions;

​

| ● | changes in securities analysts’ estimates of our financial performance;

​

| ● | regulatory developments in the United States and foreign countries;

​

| ● | fluctuations in stock market prices and trading volumes of similar companies;

​

| ● | news about the markets in which we compete or regarding our competitors;

​

| ● | terrorist acts or military action related to international conflicts, wars or otherwise;

​

| ● | sales of large blocks of our common stock, including sales by our executive officers, directors and significant stockholders; and

​

| ● | additions or departures of key personnel.

​

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 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

50

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.

​

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:

​

| ● | hire additional engineers and other personnel;

​

| ● | develop new or enhance existing products and services;

​

| ● | enhance our operating infrastructure;

​

| ● | fund working capital requirements;

​

| ● | acquire complementary businesses or technologies; or

​

| ● | otherwise respond to competitive pressures.

​

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. We have obtained capital from the Credit Facilities noted above including the Term Loan Facility and Revolving Facility. We cannot assure you that additional financing will be available on terms favorable to us, or at all. Our current Credit Facilities contain, 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 management, whose interests may not be aligned with yours, is able to exert significant influence over all matters requiring stockholder approval.

​

As of June 23, 2021, our directors, executive officers and their affiliates collectively beneficially owned 1,930,435 shares, or approximately 8%, of our total outstanding shares of common stock. Accordingly, our directors and executive officers as a group may be able to exert significant influence over 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.

​

Delaware law and anti-takeover provisions in our organizational documents may discourage our acquisition by a third party, which could make it more difficult to acquire us and limit your ability to sell your shares at a premium.

​

Our certificate of incorporation and bylaws contain certain provisions that reduce the probability of a change of control or acquisition of our company, even if such a transaction would be beneficial to our stockholders. These provisions include, but are not limited to:

​

| ● | the ability of our board of directors to issue preferred stock in one or more series of with such rights, obligations and preferences as the board may determine, without further vote or action by our stockholders;

​

51

Table of Contents

| ● | advanced notice procedures for stockholders to nominate candidates for election to the board of directors and for stockholders to submit proposals for consideration at a meeting of stockholders;

​

| ● | the absence of cumulative voting rights for our stockholders;

​

​

We are also subject to Section 203 of the Delaware General Corporation Law which, subject to certain exceptions, prohibits “business combinations” between a publicly-held Delaware corporation and an “interested stockholder,” which is generally defined as a stockholder who becomes a beneficial owner of 15% or more of a Delaware corporation’s voting stock for a three-year period following the date that such stockholder became an interested stockholder. This statute, as well as the provisions in our organizational documents, could have the effect of delaying, deterring or preventing certain potential acquisitions or a change in control of us.

Item 2. Propertie s.

​

All of our facilities are leased. Effective June 2021, our corporate headquarters are located in Arlington, Virginia where we lease approximately 2,000 square feet under an agreement expiring in November 2024. We also lease a total of approximately 280,000 square feet of space in Simi Valley, California, which leases expire between 2022 and 2027, and approximately 150,000 square feet of space in Moorpark, California, which lease expires in 2023, used to design, engineer, test and manufacture UAS. We also lease other facilities in California, Alabama, Kansas, Massachusetts, Minnesota, and Virginia that are used for administration, research and development, logistics, testing and manufacturing. Additionally, in May 2021, we acquired Telerob which has operations in Pennsylvania and Stuttgart, Germany. We believe that our facilities are in good condition and are adequate and suitable to meet our needs for the foreseeable future.

​

As of April 30, 2021, our business segments had significant operations at the following locations:

​

| ● | UAS: Simi Valley, CA; Moorpark, CA; Huntsville, AL; Lawrence, KS; Wilmington, MA; and Minneapolis, MN

| ● | MUAS: Petaluma, CA and Rohnert Park, CA

| ● | Corporate: Arlington, VA and Simi Valley, CA

​

Item 3. Legal Proceeding s.

​

On February 22, 2019, Webasto filed a lawsuit, which was subsequently amended on April 5, 2019, against us in Delaware Superior Court, arising from the sale of the EES Business to Webasto in June 2018. Webasto again amended the complaint in May 2021 to include additional claims. The lawsuit generally alleges several claims against us for breach of contract, indemnity, declaratory judgment, and fraud and misrepresentation, including allegations regarding inaccuracy of certain diligence disclosures, financial disclosures, failure to provide certain consents to contract assignments and related to the previously announced recall. Webasto seeks to recover the costs of the recall and other damages totaling over $100 million in addition to attorneys’ fees, costs, and punitive damages. Additionally, Webasto is seeking a declaratory judgment that we did not meet the requirements to receive the additional $6.5 million of the

52

Table of Contents

purchase price which was held back at the closing of the transaction (the “Holdback Amount”). On August 16, 2019, we filed our answer to Webasto’s amended complaint filed in April 2019 and a counterclaim against Webasto seeking payment of the Holdback Amount and declaratory relief regarding Webasto’s cancellation of an assigned contract. We have not yet filed an answer to Webasto’s amended complaint filed in May 2021. As to the Webasto lawsuit, our initial evaluation is that many of the allegations are meritless and that we lack sufficient information to fully analyze other allegations at this time. Discovery in this lawsuit is ongoing and, as of the date if this filing, parties are negotiating a new trial date, likely to occur sometime in 2022. At present, the parties continue the written phase of discovery and have begun taking depositions. We expect nationwide court closures and restrictions resulting from the global COVID-19 pandemic to continue easing, but we expect the possibility of another trial continuance to account for pandemic-related delays, and therefore trial could be pushed into 2023.

​

In order to avoid the future cost, expense, and distraction of continued litigation, we have engaged in settlement negotiations with Webasto. The negotiations did not result in a settlement of any of our or Webasto’s claims, however, we were required to establish reserve related to this litigation as a result of our good faith offer to settle the claims. The offer and resulting reserve do not reflect our view of the merits of the claims made in the litigation, and we continue to vigorously defend all claims.

​

On August 14, 2019, Benchmark, the company that assembled the products subject to the recall, served a demand for arbitration to AeroVironment and Webasto pursuant to its contracts with AeroVironment and Webasto, respectively. In December 2019, Benchmark dismissed, without prejudice, all claims against us in the demand for arbitration. The recall remains a significant part of our pending litigation with Webasto. In January 2021, Webasto also filed a lawsuit against Area 51, the subcontracted supplier of the part that allegedly led to the recall. That case is in the early stages in Orange County Superior Court. Any recovery that Webasto may obtain from Area 51 will likely be an offset to any recovery Webasto might obtain from us in our lawsuit.

​

We are subject to lawsuits, government investigations, audits and other legal proceedings from time to time in the ordinary course of our business. It is not possible to predict the outcome of any legal proceeding with any certainty. The outcome or costs we incur in connection with a legal proceeding could adversely impact our operating results and financial position.

Issuer Purchases of Equity Securities

​

On September 24, 2015, we announced that on September 23, 2015 our Board of Directors authorized a share repurchase program (the “Share Repurchase Program”), pursuant to which we may repurchase up to $25 million of our common stock from time to time, in amounts and at prices we deem appropriate, subject to market conditions and other considerations. Share repurchases may be executed through open market transactions or negotiated purchases and may be made under a Rule 10b5-1 plan. There is no expiration date for the program. The Share Repurchase Program does not obligate us to acquire any particular amount of common stock and may be suspended at any time by our Board of Directors. We did not repurchase any shares during the fiscal year ended April 30, 2021. As of April 30, 2021, approximately $21.2 million remained authorized for future repurchases under this program.

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

​

Introduction

​

The following discussion of our financial condition and results of operations should be read in conjunction with our “Selected Consolidated Financial Data” and our consolidated financial statements and notes thereto included herein as Item 8. This discussion contains forward-looking statements. Refer to “Forward-Looking Statements” on page 2 and “Risk Factors” beginning on page 23, for a discussion of the uncertainties, risks and assumptions associated with these statements. The disclosures and references in this Annual Report, including financial data, management’s discussion and analysis of financial condition and results of operation do not include the Telerob Group acquisition, unless otherwise specifically noted. The assets, liabilities and results of operations of the Telerob Group have not been consolidated into our results as of and for the period ended April 30, 2021 or any of the historical periods presented.

​

On June 29, 2018, we completed the sale of substantially all of the assets and related liabilities of our former EES Business to Webasto pursuant to the Purchase Agreement between Webasto and us. We determined that the EES Business met the criteria for classification as an asset held for sale at April 30, 2018 and represented a strategic shift in our operations. Therefore, the assets and liabilities and the results of operations of the EES Business are reported in this Annual Report as discontinued operations for all periods presented.

​

Overview

​

We design, develop, produce, deliver and support a technologically-advanced portfolio of intelligent, multi-domain robotic systems and related services for government agencies and businesses. We supply unmanned aircraft systems (“UAS”), tactical missile systems (“TMS”), unmanned ground vehicles (“UGV”) and related services primarily to organizations within the U.S. Department of Defense (“DoD”) and to international allied governments. We derive the majority of our revenue from these business areas and we believe that the markets for these solutions offer the potential for significant long-term growth. Additionally, we believe that some of the innovative potential products, services and technologies in our research and development pipeline will emerge as new growth platforms in the future, creating additional market opportunities.

​

The success we have achieved with our current products and services stems from our investment in research and development and our ability to invent and deliver advanced solutions, utilizing our proprietary technologies, to help our government and commercial customers operate more effectively and efficiently. We develop these highly innovative solutions by working very closely with our key customers and solving their most important challenges related to our areas of expertise. Our core technological capabilities, developed through nearly 50 years of innovation, include robotics and robotics systems autonomy; sensor design, development, miniaturization and integration; embedded software and firmware; miniature, low power wireless digital communications; lightweight aerostructures; high-altitude systems design, integration and operations; machine vision, machine learning and autonomy; low SWaP (Size, Weight and Power) system design and integration; manned-unmanned teaming, unmanned-unmanned teaming; power electronics and electric propulsion systems; efficient electric power conversion, storage systems and high density energy packaging; controls and systems integration; vertical takeoff and landing flight, fixed wing flight and hybrid aircraft flight; image stabilization and target tracking; advanced flight control systems; fluid dynamics; human-machine interface development; and integrated mission solutions for austere environments.

​

Our business focuses primarily on the design, development, production, marketing, support and operation of innovative UAS and TMS and the delivery of UAS-related services that provide situational awareness, remote sensing, multi-band communications, force protection and other information and mission effects to increase the safety and effectiveness of our customers’ operations.

​

Due to the COVID-19 pandemic, there are currently limitations on international travel which may limit our ability to obtain international orders and perform training and other services for our customers. If these travel limitations continue for an extended period of time, we may experience delays in obtaining additional international orders.

​

Table of Contents

Revenue

​

We generate our revenue primarily from the sale, support and operation of our UAS and TMS as well as ISR services by our medium UAS. Support for our small UAS and TMS customers includes training, spare parts, product repair, product replacement, and the customer-contracted operation of our small UAS by our personnel. Under ISR services contracts we deliver the information our medium UAS produce to our customers, who use that information to support their missions. We refer to these support activities, in conjunction with customer-funded research and development (“R&D”), as our services operation. We derive most of our small UAS revenue from fixed-price and cost-plus-fee contracts with the U.S. government and allied foreign governments.

​

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, depreciation of in-service ISR assets, amortization of acquired intangible assets and other costs that are not directly charged to a specific contract.

​

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.

​

Selling, General and Administrative

​

Our selling, general and administrative expenses (“SG&A”), include salaries and other expenses related to selling, marketing and proposal activities, and other administrative costs and amortization of acquired intangible assets. Some SG&A expenses relate to marketing and business development activities that support both ongoing business areas as well as new and emerging market areas. These activities can be directly associated with developing requirements for and applications of capabilities created in our R&D activities. 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.

​

Research and Development Expense

​

R&D is an integral part of our business model. We normally conduct significant internally funded R&D. Our R&D activities focus specifically on creating capabilities that support our existing product portfolio as well as new solutions.

​

Other Income and Expenses

​

Other income and expenses includes legal accruals related to our former EES Business, a one-time gain from a litigation settlement, income from transition services performed on behalf of the buyer of the discontinued EES Business, interest income, interest expense, and amortization of capital lease payments.

​

Income Tax Expense

​

Our effective tax rates are lower than the statutory rates primarily due to R&D tax credits, foreign derived intangible income tax deduction (“FDII”) and excess tax benefit of equity awards, partially offset by valuation allowances.

​

Equity Method Investment Loss, Net of Tax

​

Equity method investment loss, net of tax, includes equity method gain or loss related to the HAPSMobile Inc. joint venture we formed in December 2017 with SoftBank Corp and our investment in a limited partnership fund for which we have concluded we have influence for holding more than a minor interest.

Loss from Discontinued Operations, Net of Tax

​

On June 29, 2018, we completed the sale of substantially all of the assets and related liabilities of our former EES Business to Webasto pursuant to the Purchase Agreement between Webasto and us. We determined that the EES Business met the criteria for classification as an asset held for sale at April 30, 2018 and represented a strategic shift in our operations. Therefore, the assets and liabilities and the results of operations of the EES Business are reported in this Annual Report as discontinued operations for all periods presented.

​

Net Loss Attributable to Noncontrolling Interests

​

Net loss attributable to noncontrolling interests includes the 15% interest in the income or losses of our Turkish joint venture, Altoy.

​

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, inventory reserves for excess and obsolescence, intangible assets acquired in a business combination, goodwill, 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. Please see Note 1 to our consolidated financial statements, which are included in Item 8 “Financial Statements and Supplementary Data” of this Annual Report, for our Organization and 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. Management judgments and estimates have been applied consistently and have been reliable historically. We believe that there are two key factors which impact the reliability of management’s estimates. The first of those key factors is that the terms of our contracts are typically less than six months. The short-term nature of such contracts reduces the risk that material changes in accounting estimates will occur on the basis of market conditions or other factors. The second key factor is that we have hundreds of contracts in any given accounting period, which reduces the risk that any one change in an accounting estimate on one or several contracts would have a material impact on our consolidated financial statements.

​

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, cost-reimbursable, or time and materials. We account for all revenue contracts in accordance with ASC Topic 606, Revenue from Contracts with Customers (“ASC 606”). A performance obligation is a promise in a contract to transfer distinct goods or services to a customer, and it is the unit of account in ASC 606. A contract’s transaction price is allocated to each distinct performance obligation and revenue is recognized when each performance obligation under the terms of a contract is satisfied. For contracts with

58

Table of Contents

multiple performance obligations, we allocate the contract’s transaction price to each performance obligation using observable standalone selling prices for similar products and services. When the standalone selling price is not directly observable, we use our best estimate of the standalone selling price of each distinct good or service in the contract using the cost plus reasonable margin approach.

​

Our performance obligations are satisfied over time or at a point in time. Revenue for TMS product deliveries and Customer-Funded R&D contracts is recognized over time as costs are incurred. Contract services revenue is composed of revenue recognized on contracts for the provision of services, including repairs and maintenance, training, engineering design, development and prototyping activities, and technical support services. Contract services revenue, including ISR services, is recognized over time as services are rendered. We elected the right to invoice practical expedient in which if an entity has a right to consideration from a customer in an amount that corresponds directly with the value to the customer of the entity’s performance completed to date, such as flight hours for ISR services, the entity may recognize revenue in the amount to which the entity has a right to invoice. Training services are recognized over time using an output method based on days of training completed. For performance obligations satisfied over time, revenue is generally recognized using costs incurred to date relative to total estimated costs at completion to measure progress. Incurred costs represent work performed, which correspond with, and thereby best depict, transfer of control to the customer. Contract costs include labor, materials, subcontractors’ costs, other direct costs, and indirect costs applicable on government and commercial contracts.

​

For performance obligations which are not satisfied over time per the aforementioned criteria above, revenue is recognized at the point in time in which each performance obligation is fully satisfied. Our small and medium UAS product sales revenue is composed of revenue recognized on contracts for the delivery of small and medium UAS systems and spare parts. Revenue is recognized at the point in time when control transfers to the customer, which generally occurs when title and risk of loss have passed to the customer.

​

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 the estimated costs to complete for contracts using the over time method are recognized on a cumulative catch-up basis in the period in which the revisions are made. During the fiscal years ended April 30, 2021, 2020 and 2019, changes in accounting estimates on contracts recognized using the over time method are presented below. Amounts representing contract change orders or claims are included in revenue if the order or claim meets the criteria of a contract or contract modification in accordance with ASC 606. 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.

​

For the years ended April 30, 2021, 2020 and 2019, favorable and unfavorable cumulative catch-up adjustments included in revenue were as follows (in thousands):

​

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | Year Ended April 30, |
​ | ​ | 2021 |  | 2020 |  | 2019 | ​
​ |  | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ |
Gross favorable adjustments | ​ | $ | 1,953 | ​ | $ | 2,181 | ​ | $ | 1,190 | ​
Gross unfavorable adjustments | ​ |  | (2,205) | ​ |  | (2,019) | ​ |  | (1,308) | ​
Net adjustments | ​ | $ | (252) | ​ | $ | 162 | ​ | $ | (118) | ​

​

For the year ended April 30, 2021, favorable cumulative catch up adjustments of $2.0 million were primarily due to final cost adjustments on 12 contracts, which individually were not material. For the same period, unfavorable cumulative catch up adjustments of $2.2 million were primarily related to higher than expected costs on nine contracts. During the year ended April 30, 2021, we revised our estimates of the total expected costs to complete a TMS variant contract. The aggregate impact of these adjustments in contract estimates on revenue related to performance obligations satisfied or partially satisfied in previous periods was a decrease to revenue of approximately $1.0 million.

​

59

Table of Contents

For the year ended April 30, 2020, favorable cumulative catch-up adjustments of $2.2 million were primarily due to final cost adjustments on 13 contracts. During the year ended April 30, 2020, we revised our estimates of the total expected costs to complete a design and development agreement. The aggregate impact of these adjustments in contract estimates on revenue related to performance obligations satisfied or partially satisfied in previous periods was an increase to revenue of approximately $1.1 million. For the same period, unfavorable cumulative catch-up adjustments of $2.0 million were primarily related to higher than expected costs on seven contracts. During the year ended April 30, 2020, we revised our estimates of the total expected costs to complete a TMS contract. The aggregate impact of these adjustments in contract estimates on revenue related to performance obligations satisfied or partially satisfied in previous periods was a decrease to revenue of approximately $1.4 million.

​

For the year ended April 30, 2019, favorable cumulative catch up adjustments of $1.2 million were primarily due to final cost adjustments on nine contracts, which individually were not material. For the same period, unfavorable cumulative catch up adjustments of $1.3 million were primarily related to higher than expected costs on 14 contracts, which individually were not material.

​

Inventories Reserves 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 net realizable value based on assumptions about future demand and market conditions and record to cost of sales. We may be required to record additional inventory write-downs if actual market conditions are less favorable than those projected by our management.

​

Intangible Assets – Acquired in Business Combinations

​

We perform valuations of assets acquired and liabilities assumed on each acquisition accounted for as a business combination and allocate the purchase price of each acquired business to our respective net tangible and intangible assets. Acquired intangible assets include: technology, in-process research and development, customer relationships, licenses, trademarks and tradenames, and non-compete agreements. We use valuation techniques to value these intangibles assets, with the primary technique being a discounted cash flow analysis. A discounted cash flow analysis requires us to make various assumptions and estimates including projected revenue, gross margins, operating costs, growth rates, useful lives and discount rates. Intangible assets are amortized over their estimated useful lives using the straight-line method which approximates the pattern in which the economic benefits are consumed.

​

Goodwill

​

Goodwill represents the excess of the cost of an acquired entity over the fair value of the acquired net assets. We test goodwill for impairment annually during the fourth quarter of the Company’s fiscal year or when events or circumstances change in a manner that indicates goodwill might be impaired. Events or circumstances that could trigger an impairment review include, but are not limited to, a significant adverse change in legal factors or in the business or political climate, an adverse action or assessment by a regulator, unanticipated competition, a loss of key personnel, significant changes in the manner of the Company’s use of the acquired assets or the strategy for the Company’s overall business, significant negative industry or economic trends or significant underperformance relative to projected future results of operations.

​

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 tax 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

Fiscal Year Ended April 30, 2021 Compared to Fiscal Year Ended April 30, 2020

​

Revenue. Revenue for the fiscal year ended April 30, 2021 was $394.9 million, as compared to $367.3 million for the fiscal year ended April 30, 2020, representing an increase of $27.6 million, or 8%. The increase in revenue was due to an increase in product revenue of $22.1 million and an increase in service revenue of $5.5 million. UAS segment revenue increased $11.8 million from fiscal 2020, or 3%, to $379.1 million for the fiscal year ended April 30, 2021 due to an increase in product deliveries of $21.8 million, partially offset by a decrease in service revenue of $10.0 million. The increase in product deliveries was primarily due to an increase in product deliveries of TMS and small UAS. The decrease in service revenue was primarily due to a decrease in customer-funded R&D primarily associated with a design and development agreement, partially offset by customer-funded R&D primarily associated with TMS. MUAS segment recorded revenue of $15.8 million for the fiscal year ended April 30, 2021 resulting from our acquisition of Arcturus in February 2021.

​

Cost of Sales. Cost of sales for the fiscal year ended April 30, 2021 was $230.4 million, as compared to $214.2 million for the fiscal year ended April 30, 2020, representing an increase of $16.2 million, or 8%. As a percentage of revenue, cost of sales remained consistent at 58%. The increase in cost of sales was a result of an increase in product cost of sales of $10.6 million and an increase in service costs of sales of $5.6 million. UAS cost of sales increased $3.3 million to $217.5 million for the fiscal year ended April 30, 2021 primarily due to an increase in product sales, partially offset by a decrease in service revenues. As a percentage of revenue, UAS cost of sales decreased from 58% to 57%, primarily due to a favorable product mix. MUAS recorded cost of sales of $12.9 million for the fiscal year ended April 30, 2021 resulting from our acquisition of Arcturus in February 2021. Cost of sales for fiscal 2021 included $1.7 million and $2.8 million of intangible amortization expense and other related non-cash purchase accounting expense related to increasing the carrying value of certain assets to fair value for MUAS and UAS, respectively, as compared to $2.4 million for UAS in fiscal 2020.

​

Gross Margin. Gross margin for the fiscal year ended April 30, 2021 was $164.6 million, as compared to $153.1 million for the fiscal year ended April 30, 2020, representing an increase of $11.5 million, or 7%. As a percentage of revenue, gross margin remained consistent at 42%. The increase in gross margin was primarily due to an increase in product margin of $11.5 million. UAS gross margin increased $8.5 million to $161.6 million for the fiscal year ended April 30, 2021 primarily due to an increase in product sales, partially offset by a decrease in service revenues and a favorable mix. As a percentage of revenue, UAS gross margin increased from 42% to 43%, primarily due to a favorable product mix. MUAS gross margin was $3.0 million for the fiscal year ended April 30, 2021 resulting from our acquisition of Arcturus in February 2021.

Selling, General and Administrative. SG&A expense for the fiscal year ended April 30, 2021 was $67.5 million, or 17% of revenue, compared to SG&A expense of $59.5 million, or 16% of revenue, for the fiscal year ended April 30, 2020. The increase in SG&A expense was primarily due to an increase in acquisition related expenses of $6.5 million primarily related to the acquisition of Arcturus, ISG and Telerob and an increase in intangible amortization expense of $2.8 million.

​

Research and Development. R&D expense for the fiscal year ended April 30, 2021 was $53.8 million, or 14% of revenue, compared to R&D expense of $46.5 million, or 13% of revenue, for the fiscal year ended April 30, 2020. R&D expense increased primarily due to an increase in development activities regarding enhanced capabilities for our products and development of new product lines.

​

Interest (Expense) Income, net. Interest expense, net for the fiscal year ended April 30, 2021 was $0.6 million, compared to interest income net of $4.8 million for the fiscal year ended April 30, 2020. The increase in interest expense is primarily due to a combination of a decrease in the average interest rates earned on our investments portfolio and a decrease in the average investment balances and an increase in interest expense of $0.9 million resulting from the term debt issued concurrent with the acquisition of Arcturus.

​

Other (Expense) Income, net. Other expense, net for the fiscal year ended April 30, 2021 was $8.3 million, as compared to other income, net of $0.7 million for the fiscal year ended April 30, 2020. The increase in other expense, net was primarily due to a legal accrual related to our former EES Business.

​

Income Taxes. Our effective income tax rate was 1.6% for the fiscal year ended April 30, 2021, as compared to 11.1% for the fiscal year ended April 30, 2020. The decrease in our effective tax rate was primarily due to the decrease in income before income taxes and an increase in certain federal income tax credits.

​

Equity method investment loss, net of tax. Equity method investment loss, net of tax for the fiscal year ended April 30, 2021 was $10.5 million, as compared to equity method investment loss, net of $5.5 million for the fiscal year ended April 30, 2020. The increase was primarily due to a loss of $8.4 million for our proportionate share of the HAPSMobile Inc. joint venture’s impairment of its investment in Loon LLC.

​

Loss on sale of business, net of tax. Loss on sale of business, net of tax for the fiscal year ended April 30, 2021 was $0, as compared to $0.3 million for the fiscal year ended April 30, 2020. The loss on sale of business, net of tax related to the sale of our former EES Business during the fiscal year ended April 30, 2019. We recorded an adjustment related to a settled working capital dispute during the fiscal year ended April 30, 2020.

​

Fiscal Year Ended April 30, 2020 Compared to Fiscal Year Ended April 30, 2019

​

Revenue. Revenue for the fiscal year ended April 30, 2020 was $367.3 million, as compared to $314.3 million for the fiscal year ended April 30, 2019, representing an increase of $53.0 million, or 17%. The increase in revenue was due to an increase in product revenue of $44.7 million and an increase in service revenue of $8.3 million. The increase in product revenue was primarily due to an increase in product deliveries of small UAS to customers within the U.S. government and an increase in TMS revenue from customers within the U.S. government, partially offset by a slight decrease in product deliveries of small UAS to international customers. The increase in product deliveries of small UAS included product deliveries of our VAPOR helicopter unmanned aircraft system associated with our acquisition of Pulse Aerospace in June 2019. The increase in service revenue was primarily due to an increase in customer-funded R&D work primarily associated with our design and development agreement with HAPSMobile, development efforts for customers within the U.S. government, an increase in other engineering services, and an increase in sustainment activities in support of TMS product deliveries, partially offset by a decrease in customer-funded R&D work associated with TMS and TMS variants.

​

Cost of Sales. Cost of sales for the fiscal year ended April 30, 2020 was $214.2 million, as compared to $185.9 million for the fiscal year ended April 30, 2019, representing an increase of $28.3 million, or 15%. The increase in cost of sales was a result of an increase in product cost of sales of $25.6 million and an increase in service costs of sales of $2.7 million. The increase in product costs was primarily due to the increase in product deliveries and an increase of $2.5

Table of Contents

million in intangible asset amortization expense associated with our acquisition of Pulse Aerospace in June 2019. The increase in service costs of sales was primarily due to the increase in service revenue, partially offset by a favorable service mix. As a percentage of revenue, cost of sales decreased from 59% to 58%, primarily due to an increase in the proportion of product sales to total revenue and a favorable service mix, partially offset by acquired intangible asset amortization expense.

​

Gross Margin. Gross margin for the fiscal year ended April 30, 2020 was $153.1 million, as compared to $128.4 million for the fiscal year ended April 30, 2019, representing an increase of $24.7 million, or 19%. The increase in gross margin was primarily due to an increase in product margins of $19.0 million and an increase in service margins of $5.7 million. The increase in product margins was primarily due to the increase in product deliveries, partially offset by an increase of $2.5 million in intangible asset amortization expense associated with our acquisition of Pulse Aerospace in June 2019. The increase in services margins was primarily due to the increase in services revenue and a favorable service mix. As a percentage of revenue, gross margin increased from 41% to 42%, primarily due to an increase in the proportion of product sales to total revenue and a favorable service mix, partially offset by acquired intangible asset amortization expense. As a percentage of revenue, product gross margin for fiscal 2020 decreased by nearly 70 basis points to 46%. We anticipate product margin in fiscal year 2021 to continue to decline primarily due to an unfavorable product mix.

​

Selling, General and Administrative. SG&A expense for the fiscal year ended April 30, 2020 was $59.5 million, or 16% of revenue, compared to SG&A expense of $60.3 million, or 19% of revenue, for the fiscal year ended April 30, 2019. The decrease in SG&A expense was primarily due to a $4.4 million impairment charge related to the long-lived assets of our commercial Quantix product during the fiscal year ended April 30, 2019, a decrease in corporate development expenses primarily related to the sale of our EES Business and a decrease in costs incurred related to the transition services agreement with Webasto, partially offset by an increase in employee-related expenses and an increase in commission expenses associated with an increase in the number of international small UAS contracts under which we utilized sales agents.

​

Research and Development. R&D expense for the fiscal year ended April 30, 2020 was $46.5 million, or 13% of revenue, compared to R&D expense of $34.2 million, or 11% of revenue, for the fiscal year ended April 30, 2019. R&D expense increased primarily due to increased development activities for certain strategic initiatives.

​

Interest Income, net. Interest income, net for the fiscal year ended April 30, 2020 was $4.8 million, compared to $4.7 million for the fiscal year ended April 30, 2019. The increase in interest income was primarily due to an increase in the average interest rates earned on our investments portfolio, partially offset by a decrease in our investments balances. Due to the significant decline in market interest rates combined with a shift in our investment composition towards U.S. government and U.S. government agency securities during the fourth quarter of fiscal year 2020, we anticipate interest income earned on our investments portfolio to decrease in future periods.

​

Other Income (Expense), net. Other income, net for the fiscal year ended April 30, 2020 was $0.7 million, as compared to other income, net of $12.0 million for the fiscal year ended April 30, 2019. The decrease in other income, net was primarily due to a one-time litigation settlement during the fiscal year ended April 30, 2019 and a decrease in income earned under a transition services agreement with Webasto, the buyer of our former EES Business.

​

Income Taxes. Our effective income tax rate was 11.1% for the fiscal year ended April 30, 2020, as compared to 9.2% for the fiscal year ended April 30, 2019. The increase in our effective tax rate was primarily due to decrease in excess tax benefits from the vesting of employee equity awards and a lower proportion of R&D expense which qualifies for R&D tax credits.

​

Equity method investment loss, net of tax. Equity method investment loss, net of tax for the fiscal year ended April 30, 2020 was $5.5 million, as compared to equity method investment loss, net of $3.9 million for the fiscal year ended April 30, 2019. The increase was primarily due to the equity method loss associated with our investment in the HAPSMobile joint venture formed in December 2017.

Liquidity and Capital Resources

​

On February 19, 2021 in connection with the consummation of the Arcturus acquisition, we entered into a Credit Agreement for (i) a five-year $100 million revolving credit facility, which includes a $10 million sublimit for the issuance of standby and commercial letters of credit, and (ii) a five-year amortized $200 million term A loan (together the “Credit Facilities”). The Term Loan Facility requires payment of 5% of the outstanding obligations in each of the first four loan years, with the remaining 80.0% payable in loan year five, consisting of three quarterly payments of 1.25% each, with the remaining outstanding principal amount of the Term Loan Facility due and payable on the final maturity date. Proceeds from the Term Loan Facility were used in part to finance a portion of the cash consideration for the Arcturus acquisition. Our ability to borrow under the Revolving Facility is reduced by outstanding letters of credit of $5.0 million as of April 30, 2021. As of April 30, 2021, approximately $95.0 million was available under the Revolving Facility. Borrowings under the Revolving Facility may be used for working capital and other general corporate purposes. Refer to Note 12—Debt to our financial statements for further details.

​

On May 3, 2021, the Company paid €37,455,398.11 (approximately $45.4 million) in cash to purchase Telerob, less (a) €3,000,000 (approximately $3.6 million) to be held in escrow. Funding for the acquisition came from existing sources of liquidity, Credit Facilities, and cash flows from operations. Refer to Note 24—Subsequent Events to our financial statements for further details.

​

We anticipate funding our normal recurring trade payables, accrued expenses, ongoing R&D costs and obligations under the Credit Facilities through our existing working capital and funds provided by operating activities including those provided by our recent acquisitions of Arcturus, ISG and Telerob. The majority of our purchase obligations are pursuant to funded contractual arrangements with our customers. We believe that our existing cash, cash equivalents, cash provided by operating activities and other financing sources will be sufficient to meet our anticipated working capital, capital expenditure requirements, future obligations related to the recent acquisitions and obligations under the Credit Facilities 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 draw on our Credit Facilities. We anticipate that existing sources of liquidity, Credit Facilities, and cash flows from operations will be sufficient to satisfy our cash needs for the foreseeable future.

​

Our primary liquidity needs are for financing working capital, investing in capital expenditures, supporting product development efforts, introducing new products and enhancing existing products, marketing acceptance and adoption of our products and services and financing our acquisition of Telerob. 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, and cash from our Credit Facilities are insufficient to fund our future activities, we may need to raise additional funds through public or private equity or debt financing, subject to the limitations specified in our Credit Facility agreement. In addition, we may also need to seek additional equity funding or debt financing if we become a party to any agreement or letter of intent for potential investments in, or acquisitions of, businesses, services or technologies.

​

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

Table of Contents

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.

​

To date, COVID-19 has not had a significant impact on our liquidity, cash flows or capital resources. However, the continued spread of COVID-19 has led to disruption and volatility in the global capital markets, which, depending on future developments, could impact our capital resources and liquidity in the future. In consideration of the impact of the COVID-19 pandemic, we continue to hold a significant portion of our investments in cash and cash equivalents and U.S. government and U.S. government agency securities.

​

Although not material in value alone or in aggregate, during the fiscal year ended April 30, 2021, we made certain commitments outside of the ordinary course of business, including capital contributions of $2.7 million to a limited partnership fund. Under the terms of the limited partnership agreement, we have committed to make capital contributions totaling $10.0 million to the fund of which $2.4 million was remaining at April 30, 2021.

Cash Provided by Operating Activities. Net cash provided by operating activities for the fiscal year ended April 30, 2021 increased by $61.4 million to $86.5 million, compared to net cash provided by operating activities of $25.1 million for the fiscal year ended April 30, 2020. This increase in net cash provided by operating activities was primarily due to an increase in the cash provided as a result of changes in operating assets and liabilities of $66.9 million largely resulting from increases in accounts receivable and unbilled retentions and receivables due to year over year timing differences, partially offset by decreases in inventory primarily due to year over year timing differences in purchases to support anticipated product deliveries, and decreases in prepaid expenses and other assets due to year over year timing differences, and an increase in non-cash expenses of $12.5 million primarily due to an increase in depreciation and amortization and loss from equity method investments.

​

Net cash provided by operating activities for the fiscal year ended April 30, 2020 decreased by $1.8 million to $25.1 million, compared to net cash provided by operating activities of $26.9 million for the fiscal year ended April 30, 2019. This decrease in net cash provided by operating activities was primarily due to a decrease in the cash provided as a result of changes in operating assets and liabilities of $2.5 million largely resulting from decreases in accounts receivable due to year over year timing differences, partially offset by increases in inventory primarily due to year over year timing differences in purchases to support anticipated product deliveries, increases in unbilled retentions and receivables due to year over year timing differences in revenue and related billings, and decreases in accounts payable due to year over year timing differences, partially offset by an increase in non-cash expenses of $1.3 million primarily due to an increase in depreciation and amortization and loss from equity method investments.

​

Cash (Used in) Provided by Investing Activities. Net cash used in investing activities increased by $437.9 million to $378.7 million for the fiscal year ended April 30, 2021, compared to net cash provided by investing activities of $59.2 million for the fiscal year ended April 30, 2020. The increase in net cash used in investing activities was primarily due to the acquisitions of Arcturus and ISG, net of cash for $385.6 million in fiscal year ended April 30, 2021 and a decrease in redemptions of available-for-sale investments net of purchases. During the fiscal years ended April 30, 2021 and 2020, we used cash to purchase property and equipment totaling $11.3 million and $11.2 million, respectively.

Net cash provided by investing activities increased by $47.6 million to $59.2 million for the fiscal year ended April 30, 2020, compared to net cash provided by investing activities of $11.5 million for the fiscal year ended April 30, 2019. The increase in net cash provided by investing activities was primarily due to higher net redemptions of available-for-sale investments of $92.0 million and held-to-maturity investments of $15.4 million, partially offset by the proceeds received from the sale of the EES Business in the amount of $32.0 million in the first quarter of fiscal 2019, and the cash used to purchase Pulse Aerospace, LLC during fiscal 2020, in the amount of $18.6 million. During the fiscal years ended April 30, 2020 and 2019, we used cash to purchase property and equipment totaling $11.2 million and $8.9 million, respectively.

​

Cash Provided by (Used in) Financing Activities. Net cash provided by financing activities increased by $196.0 million to $194.2 million for the fiscal year ended April 30, 2021, compared to net cash used in financing activities of $1.8 million for the fiscal year ended April 30, 2020. The increase in net cash provided by financing activities was primarily due to the proceeds of long-term debt of $200.0 million, partially offset by payment of debt issuance costs of $3.9 million.

Net cash used in financing activities increased by $0.6 million to $1.8 million for the fiscal year ended April 30, 2020, compared to net cash used in financing activities of $1.2 million for the fiscal year ended April 30, 2019. The increase in net cash used by financing activities was primarily due to the payment of contingent consideration of $0.9 million related to the purchase of Pulse Aerospace, LLC.

​

Inflation

​

Our operations have not been, and we do not expect them to be, materially affected by inflation. Historically, we have been successful in adjusting prices to our customers to reflect changes in our material and labor costs.

​

Recently Adopted Accounting Standards

​

Effective May 1, 2020, the Company adopted Accounting Standards Update (“ASU”) 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, along with several additional clarification ASU’s issued during 2018 and 2019, collectively “CECL”. CECL requires the reporting entity to estimate expected credit losses over the life of a financial asset. CECL requires the credit loss to be recognized upon initial recognition of the financial asset. ASU 2016-13 requires the entity to adopt CECL using the modified retrospective transition approach through a cumulative-effect adjustment to the opening balance of retained earnings in

Table of Contents

the period of adoption. As part of the assessment of the adequacy of the Company’s allowances for credit losses, the Company considered a number of factors including, but not limited to, customer credit ratings, age of receivables, and expected loss rates. However, the adoption of CECL did not have a material impact to retained earnings for the Company.

​

Effective May 1, 2020, the Company adopted ASU 2018-15, “Intangibles—Goodwill and Other— Internal-Use Software (Subtopic 350-40) Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract” (“ASU 2018-15”). ASU 2018-15 provides guidance on the treatment of accounting for fees paid by a customer in a cloud computing arrangement. This guidance includes the requirements for capitalizing implementation costs incurred in a hosting arrangement. The Company adopted ASU 2018-15 using the prospective method, applying the new guidance to all implementation costs incurred after adoption. The adoption of ASU 2018-15 did not have an impact on the Company’s consolidated financial statements.

​

New Accounting Standards

​

In December 2019, the FASB issued ASU 2019-12, Simplifying the Accounting for Income Taxes (Topic 740). This ASU simplifies the accounting for income taxes by removing certain exceptions to the general principles in Topic 740. The guidance is effective for fiscal years beginning after December 15, 2020 and interim periods therein, with early adoption permitted. The adoption method is dependent on the specific amendment included in this update as certain amendments require retrospective adoption, modified retrospective adoption, an option of retrospective or modified retrospective, and prospective adoption. The Company is evaluating the potential impact of this adoption on its consolidated financial statements.

In January 2020, the FASB issued ASU 2020-01, Clarifying the Interactions between Topic 321, Topic 323, and Topic 815 (Topic 321, Topic 323, and Topic 815). This ASU clarifies accounting certain topics impacted by Topic 321 Investments—Equity Securities. These topics include measuring equity securities using the measurement alternative, how the measurement alternative should be applied to equity method accounting, and certain forward contracts and purchased options which would be accounted for under the equity method of accounting upon settlement or exercise. The guidance is effective for fiscal years beginning after December 15, 2020 and interim periods therein, with early adoption permitted. The amendments should be adopted prospectively. The Company is evaluating the potential impact of this adoption on its consolidated financial statements.

​

Item 7A. Quantitative and Qualitative Disclosures About Market Risk.

​

Interest Rate Risk

​

On February 19, 2021 in connection with the consummation of the Arcturus acquisition, we entered into the Credit Facilities. The current outstanding balance of the Credit Facilities is $200 million and bears a variable interest rate. If market interest rates increase significantly, interest due on the Credit Facilities would increase.

​

Foreign Currency Exchange Rate Risk

​

Since a significant part of our sales and expenses are denominated in U.S. dollars, we have not experienced significant foreign exchange gains or losses to date. We currently do not engage in forward contracts or other derivatives in foreign currencies to limit our exposure on non-U.S. dollar transactions. With the acquisition of Telerob, who does conduct sales denominated in Euros, we are further exposed to future foreign exchange gains or losses, and we will consider methods to limit our exposure on non-U.S. dollar transactions in the future.

Opinion on the Financial Statements

​

We have audited the accompanying consolidated balance sheets of AeroVironment, Inc. (the "Company") as of April 30, 2021 and 2020, the related consolidated statements of income, comprehensive income, stockholders' equity, and cash flows, for each of the two years in the period ended April 30, 2021, and the related notes and the schedule listed in the Index at Item 15(a) (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of April 30, 2021 and 2020, and the results of its operations and its cash flows for each of the two years in the period ended April 30, 2021, in conformity with accounting principles generally accepted in the United States of America.

​

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of April 30, 2021, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated June 29, 2021, expressed an unqualified opinion on the Company's internal control over financial reporting.

​

Change in Accounting Principle

​

As discussed in Note 1 to the financial statements, the Company adopted Accounting Standards Update No. 2016-02, Leases (Topic 842), and all related amendments to Accounting Standard Codification 842, Leases, on May 1, 2019.

Revenue Recognition - Refer to Note 1 to the financial statements

​

Critical Audit Matter Description

​

The Company’s 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 the specifications of the customers. The Company’s performance obligations under these contractual agreements are satisfied over time or at a point in time. Performance obligations are satisfied over time if the customer receives the benefits as the Company performs, if the customer controls the asset as it is being developed or produced, or if the product being produced for the customer has no alternative use and the Company has a contractual right to payment for the Company’s costs incurred to date plus a reasonable margin. For performance obligations satisfied over time, revenue is generally recognized using costs incurred to date relative to total estimated costs at completion to measure progress. Incurred costs represent work performed, which correspond with, and thereby best depict, transfer of control to the customer. Contract costs include labor, materials, subcontractors’ costs, other direct costs, and indirect costs applicable on government and commercial contracts. For contracts with multiple performance obligations, the Company allocates the contract’s transaction price to each performance obligation using its observable standalone selling price for products and services. When the standalone selling price is not directly observable, the Company uses its best estimate of the standalone selling price of each distinct good or service in the contract using the cost-plus reasonable margin approach. As of April 30, 2021, revenue was $394.9 million, of which 43% relates to revenue recognized over time.

​

We identified the assumptions related to estimating total costs and profit to be a critical audit matter given the inherent judgement involved in estimating the total costs including labor, materials, subcontractors’ costs, other direct costs and indirect costs. Auditing such estimates of total costs and profit required extensive audit effort and a high degree of auditor judgment.

​

How the Critical Audit Matter Was Addressed in the Audit

​

Our audit procedures related to management’s estimates of total costs and profit for the performance obligations used to recognize revenue for certain performance obligations accounted for over time included the following, among others:

​

| ● | We tested the effectiveness of controls for over time revenue, including management’s controls over the estimates of total costs and profit for performance obligations.

​

| ● | We tested the amount of over time revenue recorded by developing an expectation for the amount based on historical profit as a percentage of costs incurred and comparing our expectation to the amount recorded by management.

​

| ● | We selected a sample of contracts with customers and performed the following:

​

| o | Compared the transaction price to the consideration expected to be received based on current rights and obligations under the contracts and any modifications that were agreed upon with the customers.

​

| o | Tested the accuracy and completeness of the costs incurred to date for the performance obligation.

​

| o | Evaluated the estimates of total cost and profit for the performance obligation by:

​

| ◾ | Observing the work sites and inspecting the progress to completion.

​

| ◾ | Evaluating management’s ability to achieve the estimates of total costs and profit by performing corroborating inquiries with the Company’s project managers and engineers, and comparing the estimates to management’s work plans, engineering specifications, and supplier contracts.

​

| ◾ | Comparing management’s estimates for the selected contracts to costs and profits of similar performance obligations, when applicable.

​

| ● | We evaluated management’s ability to estimate total costs and profits accurately by comparing actual costs and profits to management’s historical estimates for performance obligations that have been fulfilled.

Business Acquisitions – Refer to Note 21 to the financial statements

​

Critical Audit Matter Description

​

On February 19, 2021, the Company closed its acquisition of Arcturus for total consideration of approximately $422.6 million, net of cash acquired. Additionally, on February 23, 2021 the Company purchased certain assets of, and assumed certain liabilities of, ISG for total consideration of approximately $35.4 million, which includes the Company’s estimate of contingent consideration of $5.5 million based on the achievement of certain revenue targets by ISG during the 3 years following closing. The Company accounted for the acquisitions under the acquisition method of accounting for business combinations. Accordingly, the purchase price was allocated to the assets acquired and liabilities assumed based on their respective fair values, resulting in technology of $31.9 million, customer relationships of $67.2 million and goodwill of $307.9 million. Management estimated the fair value of the intangible assets using discounted cash flow analyses, which were based on the Company’s best estimates of future sales, earnings and cash flows after considering such factors as general market conditions, anticipated customer demand, changes in working capital, long term business plans and recent operating performance. Determining the fair value of the intangible assets acquired required significant judgment, including the amount and timing of expected future cash flows and the selected discount rates.

​

We identified the assumptions related to estimating the amount and timing of expected future cash flows and discount rates to be a critical audit matter given the inherent judgment involved in estimating these amounts. Performing audit procedures to evaluate the reasonableness of these estimates and assumptions required a high degree of auditor judgment and an increased extent of effort, including the need to involve our fair value specialists.

​

How the Critical Audit Matter Was Addressed in the Audit

​

Our audit procedures applied to the amount and timing of expected future cash flows and the selection of the discount rates for intangibles included the following, among others:

​

| ● | We tested the effectiveness of controls over the valuation of intangibles, including management’s controls over the amount and timing of expected future cash flows and the selection of discount rates.

​

| ● | We assessed the reasonableness of management’s forecasts of future cash flows by performing inquiries of appropriate individuals outside of the finance organization, comparing the projections to historical results, contractual agreements, certain peer companies, third-party industry forecasts, and internal communications to management and board of directors.

​

| ● | With the assistance of our fair value specialists, we evaluated the reasonableness of (1) the valuation methodology and (2) the discount rates utilized, including testing the source information underlying the determination of the discount rates, testing the mathematical accuracy of the calculation, and developing a range of independent estimates and comparing those to the discount rates selected by management.

​

| ● | We evaluated whether the estimated future cash flows were consistent with evidence obtained in other areas of the audit.

​

Significant Accounting Policies

​

Principles of Consolidation

​

The accompanying consolidated financial statements include the accounts of AeroVironment, Inc. and its wholly-owned subsidiaries: Arcturus UAV, Inc. (“Arcturus”) and AeroVironment, Inc. (Afghanistan), as well as the Company’s Turkish joint venture, Altoy Savunma Sanayi ve Havacilik Anonim Sirketi (“Altoy”) (collectively referred to herein as the “Company”).

​

On June 29, 2018, the Company completed the sale of substantially all of the assets and related liabilities of its efficient energy systems business segment (the “EES Business”) to Webasto Charging Systems, Inc. (“Webasto”) pursuant to an Asset Purchase Agreement (the “Purchase Agreement”) between Webasto and the Company. The Company determined that the EES Business met the criteria for classification as an asset held for sale at April 30, 2018 and represented a strategic shift in the Company’s operations. Therefore, the assets and liabilities and the results of operations of the EES Business are reported as discontinued operations for all periods presented. Refer to Note 2—Discontinued Operations for further details.

​

On June 10, 2019, the Company purchased 100% of the issued and outstanding member units of Pulse Aerospace, LLC (“Pulse”) pursuant to the terms of a Unit Purchase Agreement (the “Pulse Purchase Agreement”).

Investments in Companies Accounted for Using the Equity or Cost Method

​

Investments in other non-consolidated entities are accounted for using the equity method or cost basis depending upon the level of ownership and/or the Company’s ability to exercise significant influence over the operating and financial policies of the investee. When the equity method is used, investments are recorded at original cost and adjusted periodically to recognize the Company’s proportionate share of the investees’ net income or losses after the date of investment. When net losses from an investment accounted for under the equity method exceed its carrying amount, the investment balance is reduced to zero and additional losses are not provided for as the Company is not obligated to provide additional capital. The Company resumes accounting for the investment under the equity method if the entity subsequently reports net income and the Company’s share of that net income exceeds the share of net losses not recognized during the period the equity method was suspended.

​

When an investment accounted for using the equity method issues its own shares, the subsequent reduction in the Company’s proportionate interest in the investee is reflected in equity as an adjustment to paid-in-capital. The Company evaluates its investments in companies accounted for by the equity or cost method for impairment when there is evidence or indicators that a decrease in value may be other than temporary.

​

In December of 2017, the Company and SoftBank Corp. (“SoftBank”) formed a joint venture, HAPSMobile Inc. (“HAPSMobile”). As the Company has the ability to exercise significant influence over the operating and financial policies of HAPSMobile, the Company’s investment is accounted as an equity method investment. The Company has presented its proportion of HAPSMobile’s net loss in equity method investment loss, net of tax in the consolidated statement of operations. The carrying value of the investment in HAPSMobile was recorded in other assets. Refer to Note 9 – Equity Method Investments for further details.

​

In July 2019, the Company made its initial capital contribution to a limited partnership fund focusing on highly relevant technologies and start-up companies serving defense and industrial markets. The Company accounts for investments in limited partnerships as equity method investments as the Company is deemed to have influence when it holds more than a minor interest. Refer to Note 9 – Equity Method Investments for further details.

​

Segments

​

Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the Chief Operating Decision Maker (“CODM”) in deciding how to allocate resources and in assessing performance. The Company’s CODM, who is the Chief Executive Officer, makes operating decisions, assesses performance and makes resource allocation decisions, including the focus of research and development (“R&D”), based on UAS and MUAS operating units. Accordingly, the Company operates its business as two reportable segments, UAS and MUAS.

​

Use of Estimates

​

The preparation of consolidated financial statements in conformity with generally accepted accounting principles in the United States requires management to make estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities and 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. Significant estimates made by management include, but are not limited to, valuation of: inventory, available-for-sale securities, acquired intangibles, goodwill, deferred tax assets and liabilities, useful lives of property, plant and equipment, medical and dental liabilities, warranty liabilities, long-term incentive plan liabilities and estimates of anticipated contract costs and transaction price utilized in the revenue recognition process. Actual results could differ from those estimates.

Reclassifications

​

Certain prior year amounts have been reclassified to conform to the current year presentation. Specifically, the Company’s existing intangible assets have been reclassified from other assets to intangibles, net on the consolidated balance sheet for all periods presented.

​

Cash Equivalents

​

The Company considers all highly liquid investments with an original maturity of three months or less at the time of purchase to be cash equivalents. The Company’s cash equivalents are comprised of money market funds, certificates of deposit of major financial institutions, and U.S. Treasury bills.

​

Restricted Cash

​

The Company classifies cash accounts which are not available for general use as restricted cash. Pursuant to the terms of the Arcturus Purchase Agreement, the Company maintains escrow accounts to address final purchase price adjustments post-Arcturus Closing, if any and to address Arcturus UAV’s and/or the Sellers’ indemnification obligations. The restricted funds in the escrow account are recorded in other assets on the consolidated balance sheet. As of April 30, 2021 restricted cash was $8,322,000. The Company had no restricted cash as of April 30, 2020.

​

Investments

​

The Company’s investments are accounted for as held-to-maturity reported at amortized cost and available-for-sale reported at fair value.

​

Unrealized gains and losses are excluded from earnings and reported as a separate component of stockholders’ equity, net of deferred income taxes for available-for-sale investments.

​

Gains and losses realized on the disposition of investment securities are determined on the specific identification basis and credited or charged to income. Premium and discount on investments are amortized and accreted using the interest method and charged or credited to investment income.

​

Management determines the appropriate classification of securities at the time of purchase and re-evaluates such designation as of each balance sheet date.

​

Investments are considered to be impaired when a decline in fair value is judged to be other-than-temporary. On a quarterly basis, the Company considers available quantitative and qualitative evidence in evaluating potential impairment of its investments. If the cost of an investment exceeds its fair value, the Company evaluates, among other factors, general market conditions, the duration and extent to which the fair value is less than cost, and its intent and ability to hold the investment to maturity. The Company also considers potential adverse conditions related to the financial health of the issuer based on rating agency actions. Once a decline in fair value is determined to be other-than-temporary, an impairment charge is recorded in earnings and a new cost basis in the investment is established.

​

Fair Values of Financial Instruments

​

Fair values of cash and cash equivalents, accounts receivable, unbilled receivables, retentions and accounts payable approximate cost due to the short period of time to maturity.

​

Concentration of Credit Risk

​

Financial instruments that potentially subject the Company to concentration of credit risk consist primarily of cash, cash equivalents, municipal bonds, U.S. government securities, U.S. government-guaranteed agency securities, U.S. government sponsored agency debt securities, highly rated commercial paper, highly rated corporate bonds, and accounts receivable. The Company currently invests the majority of its cash in municipal bonds, U.S. government

securities, U.S. government-guaranteed agency securities, U.S. government sponsored agency debt securities and highly rated corporate bonds. The Company’s revenue and accounts receivable are with a limited number of corporations and governmental entities. In the aggregate, 69%, 61% and 58% of the Company’s revenue came from agencies of the U.S. government for the years ended April 30, 2021, 2020 and 2019, respectively. These agencies accounted for 64% and 62% of the accounts receivable balances at April 30, 2021 and 2020, respectively. One such agency, the U.S. Army, accounted for 34%, 32% and 28% of the Company’s consolidated revenue for the years ended April 30, 2021, 2020 and 2019, respectively. The Company performs ongoing credit evaluations of its commercial customers and maintains an allowance for potential losses.

​

Accounts Receivable, Unbilled Receivables and Retentions

​

Accounts receivable represents primarily U.S. government and allied foreign governments, and to a lesser extent commercial receivables, net of allowances for doubtful accounts. Unbilled receivables represent costs in excess of billings on incomplete contracts and, where applicable, accrued profit related to government long-term contracts on which revenue has been recognized, but for which the customer has not yet been billed. Unbilled receivables are considered contract assets.

​

Retentions represent amounts withheld by customers until contract completion. At April 30, 2021 and 2020, the retention balances were $700,000 and $717,000, respectively. The Company determines the allowance for doubtful accounts based on historical customer experience, age of receivable and other currently available evidence. When a specific account is deemed uncollectible, the account is written off against the allowance. The allowance for doubtful accounts reflects the Company’s best estimate of expected credit losses over the life of the receivable; such losses have historically been within management’s expectations. An account is deemed past due based on contractual terms rather than on how recently payments have been received.

​

Inventories

​

Inventories are stated at the lower of cost (using the weighted average costing method) or net realizable value. Inventory write-offs and write-down provisions are provided to cover risks arising from slow-moving items or technological obsolescence and for market prices lower than cost. The Company periodically evaluates the quantities on hand relative to current and historical selling prices and historical and projected sales volume. Based on this evaluation, provisions are made to write inventory down to its net realizable value.

​

Long-Lived Assets

​

Property and equipment are carried at cost. Depreciation of property and equipment, including amortization of leasehold improvements, are provided using the straight-line method over the following estimated useful lives:

​

​ | ​ | ​ | ​
Machinery and equipment |  | 2 - 7 years |
Computer equipment and software |  | 2 - 5 years | ​
In-service ISR assets | ​ | 3 years | ​
Furniture and fixtures |  | 3 - 7 years | ​
Leasehold improvements |  | Lesser of useful life or term of lease | ​

​

Maintenance, repairs and minor renewals are charged directly to expense as incurred. Additions and betterments to property and equipment are capitalized at cost. When the Company disposes of assets, the applicable costs and accumulated depreciation and amortization thereon are removed from the accounts and any resulting gain or loss is included in selling, general and administrative (“SG&A”) expense in the period incurred.

​

The Company reviews the recoverability of its long-lived assets whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. The estimated future cash flows are based upon, among other things, assumptions about expected future operating performance, and may differ from actual cash flows. If the sum of the projected undiscounted cash flows (excluding interest) is less than the carrying value of the assets, the assets will be written down to the estimated fair value in the period in which the determination is made. During the fiscal

82

year ended April 30, 2019, the Company recorded an impairment loss of $4,398,000 related to the long-lived assets of its commercial UAS Quantix solution. Refer to Note 8 – Property and equipment, net.

​

Intangibles Assets — Acquired in Business Combinations

​

The Company performs valuations of assets acquired and liabilities assumed on each acquisition accounted for as a business combination and allocates the purchase price of the acquired business to the respective net tangible and intangible assets. Acquired intangible assets include technology, in-process research and development, customer relationships, trademarks and tradenames, and non-compete agreements. The Company determines the appropriate useful life by performing an analysis of expected cash flows based on historical experience of the acquired businesses. Intangible assets are amortized over their estimated useful lives using the straight-line method which approximates the pattern in which the economic benefits are consumed. The estimated useful life for the Company’s intangible assets are as follows:

​

​ | ​ | ​ | ​
Technology |  | 3 - 12 years |
Licenses |  | 3 years | ​
Customer relationships |  | 3 - 5 years | ​
In-process research and development | ​ | 3 years | ​
Trademarks and tradenames |  | 6 years | ​
Non-compete agreements | ​ | Contractual term | ​

​

The Company monitors conditions related to these assets to determine whether events and circumstances warrant a revision to the remaining amortization period. The Company tests its intangible assets with finite lives for potential impairment whenever management concludes events or changes in circumstances indicate that the carrying amount may not be recoverable. The original estimate of an asset's useful life and the impact of an event or circumstance on either an asset's useful life or carrying value involve significant judgment. No impairment was recorded for the fiscal years ended April 30, 2021, 2020 or 2019.

​

Goodwill

​

Goodwill represents the excess of the cost of an acquired entity over the fair value of the acquired net assets. Goodwill is tested for impairment annually during the fourth quarter of the Company’s fiscal year or when events or circumstances change in a manner that indicates goodwill might be impaired. Events or circumstances that could trigger an impairment review include, but are not limited to, a significant adverse change in legal factors or in the business or political climate, an adverse action or assessment by a regulator, unanticipated competition, a loss of key personnel, significant changes in the manner of the Company’s use of the acquired assets or the strategy for the Company’s overall business, significant negative industry or economic trends or significant underperformance relative to projected future results of operations. No impairment was recorded for the fiscal years ended April 30, 2021, 2020 or 2019.

​

Product Warranty

​

The Company accrues an estimate of its exposure to warranty claims based upon both current and historical product sales data and warranty costs incurred. Product warranty reserves are recorded in other current liabilities.

​

Accrued Sales Commissions

​

As of April 30, 2021 and 2020, the Company accrued sales commissions in other current liabilities of $2,716,000 and $2,842,000, respectively.

​

Self-Insurance Liability

​

The Company is self-insured for employee medical claims, subject to individual and aggregate stop loss policies. The Company estimates a liability for claims filed and incurred but not reported 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

83

Table of Contents

and paid by the Company. As of April 30, 2021 and 2020, the Company estimated and recorded a self-insurance liability in wages and related accruals of approximately $1,181,000 and $753,000, respectively.

​

Income Taxes

​

Deferred income tax assets and liabilities are computed annually for differences between the financial statement and income tax bases of assets and liabilities that will result in taxable or deductible amounts in the future. The provision for income taxes reflects the taxes to be paid for the period and the change during the period in the deferred income tax assets and liabilities. The Company records a valuation allowance to reduce the deferred tax assets to the amount of future tax benefit that is more likely than not to be realized. For uncertain tax positions, the Company determines whether it is “more likely than not” that a tax position will be sustained upon examination by the appropriate taxing authorities before any part of the benefit can be recorded in the financial statements. For those tax positions where it is “not more likely than not” that a tax benefit will be sustained, no tax benefit is recognized. Where applicable, associated interest and penalties are also recorded.

​

Customer Advances and Amounts in Excess of Cost Incurred

​

The Company receives advances, performance-based payments and progress payments from customers that may exceed costs incurred on certain contracts, including contracts with agencies of the U.S. government resulting in contract liabilities. These advances are classified as customer advances and will be offset against billings.

​

Revenue Recognition

​

The Company’s 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 the specifications of the customers. These contracts may be firm fixed price (“FFP”), cost plus fixed fee (“CPFF”), or time and materials (“T&M”). The Company considers all such contracts to be within the scope of ASC Topic 606, Revenue from Contracts with Customers (“ASC 606”).

​

Performance Obligations

​

A performance obligation is a promise in a contract to transfer distinct goods or services to a customer, and it is the unit of account in ASC 606. A contract’s transaction price is allocated to each distinct performance obligation and revenue is recognized when each performance obligation under the terms of a contract is satisfied. Revenue is measured at the amount of consideration the Company expects to receive in exchange for transferring goods or providing services. For contracts with multiple performance obligations, the Company allocates the contract’s transaction price to each performance obligation using its observable standalone selling price for products and services. When the standalone selling price is not directly observable, the Company uses its best estimate of the standalone selling price of each distinct good or service in the contract using the cost plus reasonable margin approach. This approach estimates the Company’s expected costs of satisfying the performance obligation and then adds an appropriate margin for that distinct good or service.

​

Contract modifications are routine in the performance of the Company’s contracts. In most instances, contract modifications are for additional goods and/or services that are distinct and, therefore, accounted for as new contracts.

​

The Company’s performance obligations are satisfied over time, which accounted for 43% of revenue during our fiscal year ended April 30, 2021, or at a point in time, 57%. Performance obligations are satisfied over time if the customer receives the benefits as the Company performs, if the customer controls the asset as it is being developed or produced, or if the product being produced for the customer has no alternative use and the Company has a contractual right to payment for the Company’s costs incurred to date plus a reasonable margin. The contractual right to payment is generally supported by termination for convenience clauses that allow the customer to unilaterally terminate the contract for convenience, pay the Company for costs incurred plus a reasonable profit, and take control of any work in process. Revenue for TMS product deliveries and Customer-Funded R&D contracts is recognized over time as costs are incurred. Contract services revenue is composed of revenue recognized on contracts for the provision of services, including repairs

84

Table of Contents

and maintenance, training, engineering design, development and prototyping activities, and technical support services. Contract services revenue is recognized over time as services are rendered. Typically, revenue is recognized over time using an input measure (e.g., costs incurred to date relative to total estimated costs at completion) to measure progress. Contract services revenue, including ISR services, is recognized over time as services are rendered. The Company elected the right to invoice practical expedient in which if an entity has a right to consideration from a customer in an amount that corresponds directly with the value to the customer of the entity’s performance completed to date, such as flight hours for ISR services, the entity may recognize revenue in the amount to which the entity has a right to invoice. Training services are recognized over time using an output method based on days of training completed.

​

For performance obligations satisfied over time, revenue is generally recognized using costs incurred to date relative to total estimated costs at completion to measure progress. Incurred costs represent work performed, which correspond with, and thereby best depict, transfer of control to the customer. Contract costs include labor, materials, subcontractors’ costs, other direct costs, and indirect costs applicable on government and commercial contracts.

​

For performance obligations which are not satisfied over time per the aforementioned criteria above, revenue is recognized at the point in time in which each performance obligation is fully satisfied. The Company’s small and medium UAS product sales revenue is composed of revenue recognized on contracts for the delivery of small UAS systems and spare parts. Revenue is recognized at the point in time when control transfers to the customer, which generally occurs when title and risk of loss have passed to the customer.

​

On April 30, 2021, the Company had approximately $211,796,000 of remaining performance obligations under contracts with its customers, which the Company also refers to as backlog. The Company currently expects to recognize approximately 94% of the remaining performance obligations as revenue in fiscal 2022 and an additional 6% in fiscal 2023.

​

The Company collects sales, value add, and other taxes concurrent with revenue producing activities, which are excluded from revenue when they are both imposed on a specific transaction and collected from a customer.

​

Contract Estimates

​

Accounting for contracts and programs primarily with a duration of less than six months involves the use of various techniques to estimate total contract revenue and costs. For long-term contracts, the Company estimates the total expected costs to complete the contract and recognizes revenue based on the percentage of costs incurred at period end. Typically, revenue is recognized over time using costs incurred to date relative to total estimated costs at completion to measure progress toward satisfying the Company’s performance obligations. Incurred costs represent work performed, which corresponds with, and thereby best depicts, the transfer of control to the customer. Contract costs include labor, materials, subcontractors’ costs, other direct costs, and indirect costs applicable on government and commercial contracts.

​

Contract estimates are based on various assumptions to project the outcome of future events that may span several years. These assumptions include labor productivity and availability, the complexity of the work to be performed, the cost and availability of materials, the performance of subcontractors, and the availability and timing of funding from the customer.

​

The nature of the Company’s contracts gives rise to several types of variable consideration, including penalty fees and incentive awards generally for late delivery and early delivery, respectively. The Company generally estimates such variable consideration as the most likely amount. In addition, the Company includes the estimated variable consideration to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the related uncertainty is resolved. These estimates are based on historical award experience, anticipated performance and the Company’s best judgment at the time. Because of the certainty in estimating these amounts, they are included in the transaction price of the Company’s contracts and the associated remaining performance obligations.

​

85

Table of Contents

As a significant change in one or more of these estimates could affect the profitability of the Company’s contracts, the Company regularly reviews and updates its contract-related estimates. Changes in cumulative revenue estimates, due to changes in the estimated transaction price or cost estimates, are recorded using a cumulative catch-up adjustment in the period identified for contracts with performance obligations recognized over time. If at any time the estimate of contract profitability indicates an anticipated loss on the contract, the Company recognizes the total loss in the quarter it is identified.

​

The impact of adjustments in contract estimates on the Company’s operating earnings can be reflected in either operating costs and expenses or revenue. The aggregate impact of adjustments in contract estimates on revenue related to performance obligations satisfied or partially satisfied in previous periods was not significant for the years ended April 30, 2021, 2020 or 2019. During the year ended April 30, 2021, the Company revised its estimates of the total expected costs to complete a TMS contract. The aggregate impact of these adjustments in contract estimates on revenue related to performance obligations satisfied or partially satisfied in previous periods was a decrease to revenue of approximately $1,041,000. During the year ended April 30, 2020, the Company revised its estimates of the total expected costs to complete a TMS contract and a contract associated with a design and development agreement. The aggregate impact of these adjustments in contract estimates on revenue related to performance obligations satisfied or partially satisfied in previous periods was a decrease of approximately $1,403,000 and an increase of approximately $1,099,000, respectively. No adjustment on any one contract was material to the Company’s consolidated financial statements for the years ended April 30, 2019.

Revenue by Category

​

The following tables present the Company’s revenue disaggregated by major product line, contract type, customer category and geographic location (in thousands):

​

Revenue by contract type | ​ | 2021 |  | 2020 | ​ | 2019
FFP | ​ | $ | 307,413 | ​ | $ | 269,917 | ​ | $ | 224,090

Total revenue | ​ | $ | 394,912 | ​ | $ | 367,296 | ​ | $ | 314,274

​

Each of these contract types presents advantages and disadvantages. Typically, the Company assumes more risk with FFP contracts. However, these types of contracts generally offer additional profits when the Company completes the work for less than originally estimated. CPFF contracts generally subject the Company to lower risk. Accordingly,

86

Table of Contents

the associated base fees are usually lower than fees on FFP contracts. Under T&M contracts, the Company’s profit may vary if actual labor hour rates vary significantly from the negotiated rates.

​

Contract Balances

​

The timing of revenue recognition, billings and cash collections results in billed accounts receivable, unbilled receivables, and customer advances and deposits on the consolidated balance sheet. In the Company’s services contracts, amounts are billed as work progresses in accordance with agreed-upon contractual terms, either at periodic intervals, which is generally monthly, or upon the achievement of contractual milestones. Generally, billing occurs subsequent to revenue recognition, resulting in contract assets recorded in unbilled receivables and retentions on the consolidated balance sheet. However, the Company sometimes receives advances or deposits from its customers before revenue is recognized, resulting in contract liabilities recorded in customer advances on the consolidated balance sheet. Contract liabilities are not a significant financing component as they are generally utilized to pay for contract costs within a one-year period or are used to ensure the customer meets contractual requirements. These assets and liabilities are reported on the consolidated balance sheet on a contract-by-contract basis at the end of each reporting period. For the Company’s product revenue, the Company generally receives cash payments subsequent to satisfying the performance obligation via delivery of the product, resulting in billed accounts receivable. Changes in the contract asset and liability balances during the years ended April 30, 2021 or 2020 were not materially impacted by any other factors. For the Company’s contracts, there are no significant gaps between the receipt of payment and the transfer of the associated goods and services to the customer for material amounts of consideration.

​

Revenue recognized for the years ended April 30, 2021, 2020, and 2019 that was included in contract liability balances at the beginning of each year were $5,468,000, $1,670,000 and $1,587,000, respectively.

​

Cost to Fulfill a Contract with a Customer

​

The Company recognizes assets for the costs to fulfill a contract with a customer if the costs are specifically identifiable, generate or enhance resources used to satisfy future performance obligations, and are expected to be recovered in accordance with ASC 340-40 Other Assets and Deferred Costs: Contracts with Customers. The assets related to costs to fulfill contracts with customers are capitalized and amortized over the period the related performance obligations are satisfied. As of April 30, 2021 and 2020, the Company had $1,729,000 and $0 of costs to fulfill future performance obligations on contracts considered to be probable of occurrence. Costs to fulfill a contract are recorded in prepaid expenses and other current assets on the consolidated balance sheets.

​

Stock-Based Compensation

​

Stock-based compensation is measured at the grant date based on the fair value of the award and is recognized as expense over the requisite service period, which is generally the vesting period of the respective award. No compensation cost is ultimately recognized for awards for which employees do not render the requisite service and are forfeited.

​

87

Table of Contents

Long-Term Incentive Awards

​

For long-term incentive awards outstanding as of April 30, 2021, the awards include time-based awards which vest equally over three years and performance-based awards which vest based on the achievement of a target payout established at the beginning of each performance period. The actual payout at the end of the performance period is calculated based upon the Company’s achievement of such targets. Payouts are made in shares of restricted stock which become immediately vested upon issuance.

​

At each reporting period, the Company reassesses the probability of achieving the performance targets. The estimation of whether the performance targets will be achieved requires judgment, and, to the extent actual results or updated estimates differ from the Company’s current estimates, the cumulative effect on current and prior periods of those changes will be recorded in the period estimates are revised.

​

Research and Development

​

Internally funded research and development costs (“IRAD”), sponsored by the Company relate to both U.S. government products and services and those for commercial and foreign customers. IRAD costs for the Company are recoverable and allocable under government contracts in accordance with U.S. government procurement regulations.

​

Customer-funded research and development costs are incurred pursuant to contracts (revenue arrangements) to perform research and development activities according to customer specifications. These costs are direct contract costs and are expensed to cost of sales when the corresponding revenue is recognized, which is generally as the research and development services are performed. Revenue from customer-funded research and development was approximately $74,218,000, $80,934,000 and $76,407,000 for the years ended April 30, 2021, 2020 and 2019, respectively. The related cost of sales for customer-funded research and development totaled approximately $51,395,000, $56,440,000 and $54,824,000 for the years ended April 30, 2021, 2020 and 2019, respectively.

​

In January 2017, the Company executed a cost sharing Other Transaction Agreement type contract funded by the US Federal Government to perform certain system design, development and functional testing activities specific to a new prototype UAS on a best-efforts basis. The term of the agreement was completed as of December 2020. Costs of $21,833,000 have been reimbursed to the Company as the activities were performed, while the Company was responsible for funding a minimum of $11,225,000. The Company has determined that the contract meets the criteria of ASC 912-730-05 Contractors – Federal Government and, therefore, all reimbursements are recorded as an offset to research and development expense in the consolidated statements of income. Reimbursements under the contract were $3,424,000, $8,102,000 and $5,936,000 for the fiscal years ended April 30, 2021, 2020 and 2019, respectively.

​

Lease Accounting

​

The Company adopted Accounting Standards Update (“ASU”) 2016-02, Leases (Topic 842), along with several additional clarification ASU’s issued during 2018 (“New Lease Standard”) effective May 1, 2019. The New Lease Standard requires the lessee to recognize the assets and liabilities for the rights and obligations created by leases. At contract inception the Company determines whether the contract is, or contains, a lease and whether the lease should be classified as an operating or a financing lease. Operating leases are recorded in operating lease right-of-use assets, current operating lease liabilities and non-current operating lease liabilities.

​

The Company recognizes operating lease right-of-use assets and operating lease liabilities based on the present value of the future minimum lease payments over the lease term at commencement date. The Company uses its incremental borrowing rate based on the information available at commencement date to determine the present value of future payments and the appropriate lease classification. The Company defines the initial lease term to include renewal options determined to be reasonably certain. The Company’s leases have remaining lease terms of less than one year to six years, some of which may include options to extend the lease for up to 10 years, and some of which may include options to terminate the lease after two years. None of the Company’s options to extend or terminate are reasonably certain of being exercised, and are therefore not included in the Company’s determination of lease assets and liabilities. For operating leases, the Company recognizes lease expense for these leases on a straight-line basis over the lease term.

​

88

Table of Contents

Many of the Company’s real estate lease agreements contain incentives for tenant improvements, rent holidays, or rent escalation clauses. For tenant improvement incentives, if the incentive is determined to be a leasehold improvement owned by the lessee, the Company generally records incentive as a reduction to fixed lease payments thereby reducing rent expense. For rent holidays and rent escalation clauses during the lease term, the Company records rental expense on a straight-line basis over the term of the lease. For these lease incentives, the Company uses the date of initial possession as the commencement date, which is generally when the Company is given the right of access to the space and begins to make improvements in preparation for intended use.

​

The Company does not have any finance leases. The Company does not have any material restrictions or covenants in its lease agreements, sale-leaseback transactions, land easements or residual value guarantees.

​

In determining the inputs to the incremental borrowing rate calculation, the Company makes judgments about the value of the leased asset, its credit rating and the lease term including the probability of its exercising options to extend or terminate the underlying lease. Additionally, the Company makes judgments around contractual asset substitution rights in determining whether a contract contains a lease.

​

Advertising Costs

​

Advertising costs are expensed as incurred. Advertising expenses included in SG&A expenses were approximately $675,000, $934,000 and $897,000 for the years ended April 30, 2021, 2020 and 2019, respectively.

​

Foreign Currency Transactions

​

Foreign currency transaction gains and losses are charged or credited to earnings as incurred. For the fiscal years ended April 30, 2021, 2020 and 2019, foreign currency transaction losses that are included in other (expense) income, net in the accompanying statements of income were $1,000, $1,000, and $38,000, respectively.

​

Earnings Per Share

​

Basic earnings per share are computed using the weighted-average number of common shares outstanding and excludes any anti-dilutive effects of options, restricted stock and restricted stock units. The dilutive effect of potential common shares outstanding is included in diluted earnings per share.

​

The reconciliation of diluted to basic shares is as follows:

During the years ended April 30, 2021, 2020 and 2019, certain options, shares of restricted stock and restricted stock units were not included in the computation of diluted earnings per share because their inclusion would have been anti-dilutive. The number of options, restricted stock and restricted stock units which met this anti-dilutive criterion was approximately 3,000, 3,000 and 18,000 for the years ended April 30, 2021, 2020 and 2019, respectively.

Recently Adopted Accounting Standards

​

Effective May 1, 2020, the Company adopted Accounting Standards Update (“ASU”) 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, along with several additional clarification ASU’s issued during 2018 and 2019, collectively “CECL”. CECL requires the reporting entity to estimate expected credit losses over the life of a financial asset. CECL requires the credit loss to be recognized upon initial recognition of the financial asset. ASU 2016-13 requires the entity to adopt CECL using the modified retrospective transition approach through a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. As part of the assessment of the adequacy of the Company’s allowances for credit losses, the Company considered a number of factors including, but not limited to, customer credit ratings, age of receivables, and expected loss rates. However, the adoption of CECL did not have a material impact to retained earnings for the Company.

​

Effective May 1, 2020, the Company adopted ASU 2018-15, “Intangibles—Goodwill and Other— Internal-Use Software (Subtopic 350-40) Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract” (“ASU 2018-15”). ASU 2018-15 provides guidance on the treatment of accounting for fees paid by a customer in a cloud computing arrangement. This guidance includes the requirements for capitalizing implementation costs incurred in a hosting arrangement. The Company adopted ASU 2018-15 using the prospective method, applying the new guidance to all implementation costs incurred after adoption. The adoption of ASU 2018-15 did not have a material impact on the Company’s consolidated financial statements.

​

Recently Issued Accounting Standards

​

In December 2019, the FASB issued ASU 2019-12, Simplifying the Accounting for Income Taxes (Topic 740). This ASU simplifies the accounting for income taxes by removing certain exceptions to the general principles in Topic 740. The guidance is effective for fiscal years beginning after December 15, 2020 and interim periods therein, with early adoption permitted. The adoption method is dependent on the specific amendment included in this update as certain amendments require retrospective adoption, modified retrospective adoption, an option of retrospective or modified retrospective, and prospective adoption. The Company is evaluating the potential impact of this adoption on its consolidated financial statements.

​

In January 2020, the FASB issued ASU 2020-01, Clarifying the Interactions between Topic 321, Topic 323, and Topic 815 (Topic 321, Topic 323, and Topic 815). This ASU clarifies accounting certain topics impacted by Topic 321 Investments—Equity Securities. These topics include measuring equity securities using the measurement alternative, how the measurement alternative should be applied to equity method accounting, and certain forward contracts and purchased options which would be accounted for under the equity method of accounting upon settlement or exercise. The guidance is effective for fiscal years beginning after December 15, 2020 and interim periods therein, with early adoption permitted. The amendments should be adopted prospectively. The Company is evaluating the potential impact of this adoption on its consolidated financial statements.

​

2. Discontinued Operations

​

On June 29, 2018, the Company completed the sale of substantially all of the assets and related liabilities of its efficient energy systems business segment (the “EES Business”) to Webasto Charging Systems, Inc. (“Webasto”) pursuant to an Asset Purchase Agreement (the “Purchase Agreement”) between Webasto and the Company. In accordance with the terms of the Purchase Agreement, as amended by a side letter agreement executed at the closing, the Company received cash consideration of $31,994,000 upon closing, which resulted in a gain of $11,420,000 and has been recorded in gain on sale of business, net of tax in the consolidated statements of income. During the year ended April 30, 2019, the Company recorded a reduction to the gain resulting from a working capital adjustment of $486,000. During the year ended April 30, 2020, the Company and Webasto engaged an independent accounting firm to resolve a working capital dispute with a maximum exposure of $922,000 pursuant to the terms of the Purchase Agreement. In June 2020, the independent accounting firm determined the final adjustment to the working capital dispute to be $341,000 which has been recorded net of tax as a loss of discontinued operations in the consolidated statements of income for the year ended April 30, 2020.

The Company is entitled to receive additional cash consideration of $6,500,000 (the “Holdback”) upon tendering consents to assignment of two remaining customer contracts to Webasto. The Holdback was not recorded in the Company’s consolidated financial statements as the amount was not realized or realizable as of April 30, 2021. The Company’s satisfaction of the requirements for the payment of the Holdback is currently in dispute.

​

On February 22, 2019, Webasto filed a lawsuit, which was amended in April 2019, alleging several claims against the Company for breach of contract, indemnity, and bad faith, including allegations regarding inaccuracy of certain diligence disclosures, failure to provide certain consents to contract assignments and related to a previously announced product recall. Webasto seeks to recover the costs of the recall and other damages totaling a minimum of $6,500,000 in addition to attorneys’ fees, costs, and punitive damages. On August 16, 2019, the Company filed a counterclaim against Webasto seeking payment of the Holdback and declaratory relief regarding Webasto’s cancellation of an assigned contract. Webasto again amended the complaint in May 2021 to include additional claims. The Company has not filed an answer to Webasto’s amended complaint filed in May 2021. The Company believes that the allegations are generally meritless and is mounting a vigorous defense. In order to avoid the future cost, expense, and distraction of continued litigation, the Company engaged in settlement negotiations with Webasto, however, the negotiations did not result in a settlement of any of the Company’s or Webasto’s claims. As a result of the settlement negotiations, the Company established a litigation reserve, which reserve reflects the scope of a rejected offer intended to communicate the Company’s serious and good faith intention to attempt to reach a settlement for the stated purposes. The offer did not reflect the Company’s view of the merits of the claims made, and the Company continues to vigorously defend all claims. However, as a result of the preparation of the good faith offer and the Company’s willingness to pursue settlement for that amount, the Company recorded litigation reserve expenses in the amount of $9,300,000 during the year ended April 30, 2021 recorded in other expense on the consolidated statements of operations.

​

During the three months ended October 27, 2018, Webasto filed a recall report with the National Highway Traffic Safety Administration that named certain of the Company’s EES products as subject to the recall. The Company is continuing to assess the facts giving rise to the recall. Under the terms of the Purchase Agreement, the Company may be responsible for certain costs of such recall of named products the Company manufactured, sold or serviced prior to the closing of the sale of the EES Business. On August 14, 2019, Benchmark Electronics, Inc. (“Benchmark”), the company that assembled the products subject to the recall, served a demand for arbitration to the Company and Webasto, and a third-party part supplier pursuant to its contracts with the Company and Webasto, respectively. The Company filed a responsive pleading in the Benchmark arbitration on October 29, 2019, consisting of a general denial, affirmative defenses, and a reservation of the right to file counter-claims at a later date. Webasto challenged the validity of the Benchmark arbitration by filing an action in New York Superior Court. In December 2019, Webasto and Benchmark reached a settlement of their disputed claims. Benchmark withdrew its Notice of Arbitration against Webasto and the Company, but reserved its right to pursue indemnity claims against suppliers. The recall remains a significant part of the Webasto lawsuit.

​

Concurrent with the execution of the Purchase Agreement, the Company entered into a transition services agreement (the “TSA”) to provide certain general and administrative services to Webasto for a defined period. Income from performing services under the TSA was $38,000, $551,000 and $2,758,000 and has been recorded in other income, net in the consolidated statements of income for the fiscal years ended April 30, 2021, 2020 and 2019, respectively.

4. Fair Value Measurements

​

Fair value is the price that would be received to sell an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The fair value hierarchy contains three levels as follows:

​

| ● | Level 1—Inputs to the valuation based upon quoted prices (unadjusted) for identical assets or liabilities in active markets that are accessible as of the measurement date.

​

| ● | Level 2—Inputs to the valuation include quoted prices in either markets that are not active, or in active markets for similar assets or liabilities, inputs other than quoted prices that are observable, and inputs that are derived principally from or corroborated by observable market data.

​

| ● | Level 3—Inputs to the valuation that are unobservable inputs for the asset or liability.

Pursuant to the ISG Purchase Agreement, the sellers may receive up to a maximum of $6,000,000 in additional cash consideration (“contingent consideration”), if certain revenue targets are achieved during the 3 years following closing. The contingent consideration was valued using a Black-Scholes option-pricing model. The analysis considered, among other items, contractual terms of the ISG Purchase Agreement, the Company’s discount rate, the timing of expected future cash flows and the probability that the revenue targets required for payment of the contingent consideration will be achieved. See Note 21—Business Acquisitions.

​

During the three months ended April 30, 2019, the Company determined that the continued less than forecasted sales of its Quantix commercial UAS solution, which launched during the fourth quarter of fiscal year 2018, was an indicator that the long-lived assets of this asset group may not be recoverable. As a result, the company performed an analysis and concluded that the projected undiscounted cash flows were less than the carrying value of the asset group (Step 1). As a result, the Company performed additional analysis to determine the amount of the impairment loss (Step 2) and recorded an impairment loss totaling $4,398,000 related to the long-lived assets of the commercial UAS Quantix solution, which is included in selling, general and administrative expense on the consolidated statements of income. The fair value of the asset group was determined based on a discounted cash flow model reflective of the Company’s revised cash flow estimates.

​

Depreciation expense for the years ended April 30, 2021, 2020 and 2019 was $12,793,000, $7,066,000 and $7,311,000, respectively.

9. Investments in Companies Accounted for Using the Equity Method

​

In December of 2017, the Company and SoftBank formed a joint venture, HAPSMobile, which is a Japanese corporation. As of April 30, 2021, the Company’s ownership stake in HAPSMobile was approximately 7%, with the remaining 93% held by SoftBank. In connection with the formation of the joint venture on December 27, 2017, the Company initially purchased shares of HAPSMobile representing a 5% ownership interest in exchange for an investment of 210,000,000 yen ($1,860,000). The Company subsequently purchased additional shares of HAPSMobile in order to maintain a 5% ownership stake in the joint venture. The first such purchase occurred on April 17, 2018, at which time the Company invested 150,000,000 yen ($1,407,000) for the purchase of additional shares of HAPSMobile. On January 29, 2019, the Company invested an additional 209,500,000 yen ($1,926,000) to maintain its 5% ownership stake. On February 9, 2019, the Company elected to purchase 632,800,000 yen ($5,671,000) of additional shares of HAPSMobile to increase the Company’s ownership in the joint venture from 5% to 10%, and on May 10, 2019, the Company purchased 500,000,000 yen ($4,569,000) of additional shares of HAPSMobile to maintain its 10% ownership stake. The Company’s ownership percentage was subsequently diluted from 10% to approximately 5%. On December 4, 2019, the Company purchased 540,050,000 yen ($4,982,000) of additional shares of HAPSMobile to increase its ownership stake to approximately 7%.

​

As the Company has the ability to exercise significant influence over the operating and financial policies of HAPSMobile pursuant to the applicable Joint Venture Agreement and related organizational documents, the Company’s investment is accounted for as an equity method investment. At April 30, 2021, 2020 and 2019, the Company recorded

​

12.Debt

​

In connection with the consummation of the Arcturus Acquisition on February 19, 2021, the Company, as borrower, and Arcturus, as guarantor, entered into a Credit Agreement with certain lenders, letter of credit issuers, Bank of America, N.A., as the administrative agent and the swingline lender, and BofA Securities, Inc., JPMorgan Chase Bank, N.A., and U.S. Bank National Association, as joint lead arrangers and joint bookrunners (the “Credit Agreement”).

​

The Credit Agreement and its associated Security and Pledge Agreement set forth the terms and conditions for (i) a five-year $100 million revolving credit facility, which includes a $10 million sublimit for the issuance of standby and commercial letters of credit (the “Revolving Facility”), and (ii) a five-year amortized $200 million term A loan (the “Term Loan Facility”, and together with the Revolving Facility, the “Credit Facilities”). Certain existing letters of credit issued by JPMorgan Chase Bank were reserved for under the Revolving Facility at closing and remain outstanding under the terms thereof. Upon execution of the Credit Agreement, the Company drew the full principal of the Term Loan Facility for use in the acquisition of Arcturus. The Term Loan Facility requires payment of 5% of the outstanding obligations in each of the first four loan years, with the remaining 80% payable in loan year five, consisting of three quarterly payments of 1.25% each, with the remaining outstanding principal amount of the Term Loan Facility due and payable on the final maturity date. Proceeds from the Term Loan Facility were used in part to finance a portion of the cash consideration for the Arcturus acquisition. Borrowings under the Revolving Facility may be used for working capital and other general corporate purposes.

​

The Credit Facilities provide the Company with a choice of interest rates between (a) LIBOR (with a 0% floor) plus the Applicable Margin; or (b) Base Rate (defined as the highest of (a) the Federal Funds Rate plus one-half percent (0.50%), (b) the Bank of America prime rate, and (c) the one (1) month LIBOR plus one percent (1.00%)) plus the Applicable Margin. The Applicable Margin is based upon the Consolidated Leverage Ratio (as defined in the Credit Agreement) and whether the Company elects LIBOR (ranging from 1.50 - 2.25%) or Base Rate (ranging from 0.50 - 1.25%). The Company is also responsible for certain commitment fees from 0.20-0.35% depending on the Consolidated Leverage Ratio, and administrative agent expenses incurred in relation to the Credit Facilities. In the event of a default, an additional 2% default interest rate in addition to the applicable rate if specified or the Base Rate plus Applicable Margin if an applicable rate is not specified.

​

Any borrowing under the Credit Agreement may be repaid, in whole or in part, at any time and from time to time without premium or penalty other than customary breakage costs, and any amounts repaid under the Revolving Facility may be reborrowed. Mandatory prepayments are required under the revolving loans when borrowings and letter of credit usage exceed the aggregate revolving commitments of all lenders. Mandatory prepayments are also required in connection with the disposition of assets to the extent not reinvested and unpermitted debt transactions.

​

In support of its obligations pursuant to the Credit Facilities, the Company has granted security interests in substantially all of the personal property of the Company and its domestic subsidiaries, including a pledge of the equity interests in its subsidiaries (limited to 65% of outstanding equity interests in the case of foreign subsidiaries), and the

98

Table of Contents

proceeds thereof, with customary exclusions and exceptions. The Company’s existing and future domestic subsidiaries, including Arcturus (as of the closing of its acquisition by the Company), will be guarantors for the Credit Facilities.

​

The Credit Agreement contains certain customary representations and warranties and affirmative and negative covenants, including certain restrictions on the ability of the Company and its Subsidiaries (as defined in the Credit Agreement) to incur any additional indebtedness or guarantee indebtedness of others, to create liens on properties or assets, or to enter into certain asset and stock-based transactions. In addition, the Credit Agreement includes certain financial maintenance covenants, requiring that (x) the Consolidated Leverage Ratio (as defined in the Credit Agreement) shall not be more than 3.00 to 1.00 as of the end of any fiscal quarter and (y) the Consolidated Fixed Charge Coverage Ratio (as defined in the Credit Agreement) shall not be less than 1.25 to 1.00 as of the end of any fiscal quarter. As of April 30, 2021, the Company is in compliance with all covenants.

​

The Credit Agreement contains certain customary events of default, which include failure to make payments when due thereunder, the material inaccuracy of representations or warranties, failure to observe or perform certain covenants, cross-defaults, bankruptcy and insolvency-related events, certain judgments, certain ERISA-related events, invalidity of loan documents, or a Change of Control (as defined in the Credit Agreement). Upon the occurrence and continuation of an event of default, the Lenders may cease making future loans under the Credit Agreement and may declare all amounts owing under the Credit Agreement to be immediately due and payable.

13. Leases

​

The Company leases certain buildings, land and equipment. At contract inception the Company determines whether the contract is, or contains, a lease and whether the lease should be classified as an operating or a financing lease. Operating leases are recorded in operating lease right-of-use assets, current operating lease liabilities and non-current operating lease liabilities.

​

The Company recognizes operating lease right-of-use assets and operating lease liabilities based on the present value of the future minimum lease payments over the lease term at commencement date. The Company uses its incremental borrowing rate based on the information available at commencement date to determine the present value of future payments and the appropriate lease classification. The Company defines the initial lease term to include renewal

99

Table of Contents

options determined to be reasonably certain. The Company’s leases have remaining lease terms of less than one year to nine years, some of which may include options to extend the lease for up to 10 years, and some of which may include options to terminate the lease after two years. If the Company determines it is reasonably certain of exercising an option to extend or terminate, the option is included in the Company’s determination of lease assets and liabilities. For operating leases, the Company recognizes lease expense for these leases on a straight-line basis over the lease term.

​

Many of the Company’s real estate lease agreements contain incentives for tenant improvements, rent holidays, or rent escalation clauses. For tenant improvement incentives, if the incentive is determined to be a leasehold improvement owned by the lessee, the Company generally records incentive as a reduction to fixed lease payments thereby reducing rent expense. For rent holidays and rent escalation clauses during the lease term, the Company records rental expense on a straight-line basis over the term of the lease. For these lease incentives, the Company uses the date of initial possession as the commencement date, which is generally when the Company is given the right of access to the space and begins to make improvements in preparation for intended use.

​

The Company does not have any finance leases. The Company does not have any material restrictions or covenants in its lease agreements, sale-leaseback transactions, land easements or residual value guarantees.

​

In determining the inputs to the incremental borrowing rate calculation, the Company makes judgments about the value of the leased asset, its credit rating and the lease term including the probability of its exercising options to extend or terminate the underlying lease. Additionally, the Company makes judgments around contractual asset substitution rights in determining whether a contract contains a lease.

​

On January 14, 2007, the stockholders of the Company approved the 2006 Equity Incentive Plan (“2006 Plan”) effective January 21, 2007, for officers, directors, key employees and consultants. On September 29, 2011, the stockholders of the Company approved an amendment and restatement of the 2006 Plan (“Restated 2006 Plan”). Under the Restated 2006 Plan, incentive stock options, nonqualified stock options, restricted stock awards, stock appreciation right awards, performance share awards, performance stock unit awards, dividend equivalents awards, stock payment awards, deferred stock awards, restricted stock unit awards, other stock-based awards, performance bonus awards or performance-based awards may be granted at the discretion of the compensation committee, which consists of outside directors. A maximum of 4,884,157 shares of stock may be issued pursuant to awards under the Restated 2006 Plan. The maximum number of shares of common stock with respect to one or more awards that may be granted to any one participant during any twelve month period is 2,000,000. A maximum of $5,000,000 may be paid in cash to any one participant as a performance-based award during any twelve month period. The exercise price for any incentive stock option shall not be less than 100% of the fair market value on the date of grant. Vesting of awards is established at the time of grant.

​

The Company had an equity incentive plan (“2002 Plan”) for officers, directors and key employees. Under the 2002 Plan, incentive stock options or nonqualified stock options were granted, as determined by the administrator at the time of grant. Stock purchase rights were also granted under the 2002 Plan. Options under the 2002 Plan were granted at their fair market value (as determined by the board of directors). The options became exercisable at various times over a five-year period from the grant date. The 2002 Plan was terminated on the effective date of the 2006 Plan. Awards outstanding under the 2002 Plan remain outstanding and exercisable; no additional awards may be made under the 2002 Plan.

​

The Company had a 1992 nonqualified stock option plan (“1992 Plan”) for certain officers and key employees. Options under the 1992 Plan were granted at their fair market value (as determined by the board of directors) at the date of grant and became exercisable at various times over a five-year period from the grant date. The 1992 Plan expired in August 2002.

​

No options were granted during the fiscal years ended April 30, 2021, 2020 and 2019. The fair value of stock options granted previously was estimated at the grant date using the Black-Scholes option pricing model. Assumptions included in the Black-Scholes option pricing model included the expected term of stock options, the expected volatility, the risk free interest rate, and the expected dividend yield. The expected term of stock options represents the weighted average period the Company expects the stock options to remain outstanding, based on the Company’s historical exercise and post-vesting cancellation experience and the remaining contractual life of its outstanding options. The expected volatility is based on historical volatility for the Company’s stock. The risk free interest rate is based on the implied yield on a U.S. Treasury zero-coupon bond with a remaining term that approximates the expected term of the

101

Table of Contents

option. The expected dividend yield of zero reflects that the Company has not paid any cash dividends since inception and does not anticipate paying cash dividends in the foreseeable future.

15. Long-Term Incentive Awards

​

During the three months ended August 1, 2020, the Company granted awards under its amended and restated 2006 Equity Incentive Plan (the “Restated 2006 Plan”) to key employees (“Fiscal 2021 LTIP”). Awards under the Fiscal 2021 LTIP consist of: (i) time-based restricted stock awards, which vest in equal tranches in July 2021, July 2022 and July 2023, and (ii) performance-based restricted stock units (“PRSUs”), which vest based on the Company’s achievement of revenue and operating income targets for the three-year period ending April 30, 2023. At the award date, target achievement levels for each of the financial performance metrics were established for the PRSUs, at which levels the PRSUs would vest at 100% for each such metric. Threshold achievement levels for which the PRSUs would vest at 50% for each such metric and maximum achievement levels for which such awards would vest at 250% for each such metric were also established. The actual payout for the PRSUs at the end of the performance period will be calculated based upon the Company’s achievement of the established revenue and operating income targets for the performance period. Settlement of the PRSUs will be made in fully-vested shares of common stock. During the fiscal year ended April 30, 2021, the Company recorded $1,072,000 of compensation expense related to the Fiscal 2021 LTIP.

On March 27, 2020, the U.S. government enacted the Coronavirus Aid, Relief, and Economic Security Act, or the CARES Act, a $2 trillion relief package comprising a combination of tax provisions and other stimulus measures. The CARES Act broadly provides entities tax payment relief and significant business incentives and makes certain technical corrections to the 2017 Tax Cuts and Jobs Act, or the Tax Act. The tax relief measures for entities include a five-year net operating loss carry back, increases interest expense deduction limits, acceleration of alternative minimum tax credit refunds, payroll tax relief, and a technical correction to allow accelerated deductions for qualified improvement property. The Act also provides other non-income tax benefits, including federal funding for a range of stabilization measures and emergency funding to assist those impacted by the COVID-19 pandemic. Similar legislation is being enacted in other jurisdictions in which the Company operates. ASC Topic 740, Income Taxes, requires the effect of changes in tax rates and laws on deferred tax balances to be recognized in the period in which new legislation is enacted.

18. Changes in Accounting Estimates

​

During the years ended April 30, 2021, 2020 and 2019, the Company revised its estimates at completion of various contracts recognized using the over time method, which resulted in cumulative catch up adjustments during the year in which the change in estimate occurred. The change in estimate was a result of the Company changing the total costs required to complete the contracts due to having more accurate cost information as work progressed in subsequent periods on the various contracts. During the year ended April 30, 2021, the Company revised its estimates of the total expected costs to complete a TMS variant contract. The aggregate impact of these adjustments in contract estimates on revenue related to performance obligations satisfied or partially satisfied in previous periods was a decrease to revenue of approximately $1,041,000. During the year ended April 30, 2020, the Company revised its estimates of the total

107

Table of Contents

expected costs to complete a TMS contract and a contract associated with a design and development agreement. The aggregate impact of these adjustments in contract estimates on revenue related to performance obligations satisfied or partially satisfied in previous periods was a decrease of approximately $1,403,000 and an increase of approximately $1,099,000, respectively. The changes in estimates resulted in cumulative catch-up adjustments to revenue for the years ended April 30, 2019 were not material.

​

20. Commitments and Contingencies

​

Commitments

​

The Company’s operations are conducted in leased facilities. Refer to Note 13—Leases for additional information.

​

Contingencies

​

The Company is subject to legal proceedings and claims which arise out of the ordinary course of its business. Although adverse decisions or settlements may occur, the Company, in consultation with legal counsel, believes that the final disposition of such matters will not have a material adverse effect on the consolidated financial position, results of operations or cash flows of the Company.

​

At April 30, 2021 and 2020, the Company had outstanding letters of credit totaling $5,029,000 and $2,716,000, respectively.

​

Contract Cost Audits

​

Payments to the Company on government cost reimbursable contracts are based on provisional, or estimated indirect rates, which are subject to an annual audit by the Defense Contract Audit Agency (“DCAA”). The cost audits result in the negotiation and determination of the final indirect cost rates that the Company may use for the period(s) audited. The final rates, if different from the provisional rates, may create an additional receivable or liability for the Company.

​

For example, during the course of its audits, the DCAA may question the Company’s incurred costs, and if the DCAA believes the Company has accounted for such costs in a manner inconsistent with the requirements under Federal Acquisition Regulations, the DCAA auditor may recommend to the Company’s administrative contracting officer to disallow such costs. Historically, the Company has not experienced material disallowed costs as a result of government

108

Table of Contents

audits. However, the Company can provide no assurance that the DCAA or other government audits will not result in material disallowances for incurred costs in the future.

​

The Company’s revenue recognition policy calls for revenue recognized on all cost reimbursable government contracts to be recorded at actual rates unless collectability is not reasonably assured. During the fiscal year ended April 30, 2019, the Company settled rates for its incurred cost claims with the DCAA for fiscal years 2016 and 2017 without payment of any consideration. During the fiscal year ended April 30, 2020, the Company settled rates for its incurred cost claims with the DCAA for fiscal year 2015 for an amount not significant. At April 30, 2021 and 2020, the Company had no reserve for open incurred cost claim audits.

​

21. Business Acquisitions

​

Arcturus Acquisition

​

On February 19, 2021, the Company closed its acquisition of Arcturus pursuant to the terms of the Arcturus Purchase Agreement. Arcturus, headquartered in Petaluma, California, designs, engineers, tools, and manufactures unmanned aerial and aircraft systems including airborne platforms, payloads and payload integration, ground control systems, and ground support equipment and other items and services related generally to unmanned aircraft systems.

​

Pursuant to the Arcturus Purchase Agreement, at the closing of the Arcturus Acquisition, the Company paid approximately $422,602,000, net of cash acquired (subject to certain customary adjustments and escrow arrangements set forth in the Arcturus Purchase Agreement), financed with a combination of approximately $150,218,000 of cash-on-hand, $200,000,000 of financing pursuant to the Term Loan Facility and the issuance of approximately $72,384,000 of unregistered, restricted shares of common stock. As specified in the Arcturus Purchase agreement, the number of shares issued was determined based on a value of $50,000,000 and a calculated average price as of the last business day prior to execution of the Arcturus Purchase Agreement.

​

The final cash consideration is subject to certain customary adjustments, including for net working capital, cash, debt and unpaid transaction expenses (including change in control related payments triggered by the transaction) of Arcturus at the Arcturus closing, less $6,500,000 to be held in escrow to address final purchase price adjustments post-Arcturus closing, if any (the “Adjustment Escrow”), and $1,822,500 to be held in escrow to address Arcturus’s and/or the Sellers’ indemnification obligations (the “Indemnification Escrow”). The Adjustment Escrow, less any negative post-closing adjustment to the cash consideration paid at closing, is to be released to the Arcturus Sellers upon completion of the post-Arcturus closing purchase price adjustment process; the Indemnification Escrow, less any amounts paid or reserved, is to be released to the Arcturus Sellers 12 months following the Arcturus closing. To further address potential breaches of Arcturus’s and the Sellers’ representations and warranties beyond the application of the Indemnification Escrow, the Company also obtained representation and warranty insurance policies providing $40,000,000 in coverage, subject to customary terms, exclusions and retention amounts.

Determining the fair value of the intangible assets acquired requires significant judgment, including the amount and timing of expected future cash flows, long-term growth rates and discount rates. The fair value of the intangibles assets was determined using a discounted cash flow analysis, which were based on the Company’s preliminary estimates of future sales, earnings and cash flows after considering such factors as general market conditions, anticipated customer demand, changes in working capital, long term business plans and recent operating performance. Use of different estimates and judgments could yield materially different results.

​

The goodwill is attributable to the synergies the Company expects to achieve through leveraging the acquired technology to its existing customers, the workforce of Arcturus and expected future customers in the MUAS market. For tax purposes the acquisition was treated as a stock purchase and the goodwill is not deductible.

ISG Acquisition

​

On February 23, 2021, the Company purchased certain assets of, and assumed certain liabilities of, ISG pursuant to the terms of the ISG Purchase Agreement. ISG is engaged in development of artificial intelligence-enabled computer vision, machine learning and perceptive autonomy technologies and provides related services to United States government customers.

​

In connection with the ISG Acquisition, the Company (i) paid a base purchase price of $29,700,000 in cash at closing and (ii) may pay additional cash consideration of up to $6,000,000, which is held in escrow account not controlled by the Company, based on the achievement of certain revenue targets by ISG during the 3 years following closing, in each case, subject to the terms and conditions of the ISG Purchase Agreement, including certain customary adjustments.

​

As a condition to closing pursuant to the ISG Purchase Agreement, the Company and the ISG Seller entered into certain ancillary agreements, including a transition services agreement and two subleases pursuant to which the ISG Seller will provide the Company certain services and facilities space to accommodate the transition of ISG to the Company.

​

The parties to the ISG Purchase Agreement have made representations, warranties, and covenants that are customary for a transaction of this type, including, among other things, restrictions on the ISG Seller and the Beneficial Owner from engaging in certain competitive activities, as well as mutual indemnification obligations between the Company and the ISG Seller. To supplement certain indemnifications provided by the ISG Seller, the Company obtained a representation and warranty insurance policy.

​

Pulse Acquisition

​

On June 10, 2019, the Company purchased 100% of the issued and outstanding member units of Pulse pursuant to the terms of the Pulse Purchase Agreement. The Company’s acquisition of Pulse’s helicopter UAS product family strengthens AeroVironment’s leading family of fixed-wing small unmanned aircraft systems and increases the mission capabilities of AeroVironment’s family of systems.

​

Pursuant to the Pulse Purchase Agreement, at closing, the Company paid $20,650,000 in cash, less closing indebtedness and transaction costs as defined in the Pulse Purchase Agreement, less a $250,000 retention to cover any post-closing indemnification claims, and less a $1,250,000 holdback amount, with the retention and holdback to be released to the member unit holders of Pulse, less any amounts paid or reserved, 18 months after the closing of the transactions in accordance with the terms of the Pulse Purchase Agreement. The closing cash consideration included the payoff of the outstanding indebtedness of Pulse as of the closing date. The Company financed the acquisition entirely from available cash on hand. During fiscal year ended April 30, 2021, the Company paid a total of $1,492,000 in holdback and retention payments.

​

In addition to the consideration paid at closing, the acquisition of Pulse included contingent consideration arrangements that required additional consideration to be paid by the Company to the sellers of Pulse if two specified research and development milestones were achieved by December 10, 2021 and the continued employment of specified employees. Amounts were payable upon the achievement of the milestones. The range of the undiscounted amounts the Company could pay under each of the contingent consideration agreements was zero or $2,500,000 ($5,000,000 in total if both milestones are achieved and specific key employees continued employment). The fair value of the contingent consideration recognized on the acquisition date of $1,703,000 was estimated by applying the income approach. That measure was based on significant Level 3 inputs not observable in the market. Key assumptions include (1) a discount rate of 4.5% and (2) the probability that each of the milestones would be achieved.

​

During the year ended April 30, 2020, one of the research and development milestones was achieved, and the requirements for the payout of remaining contingent consideration were concluded to not have been met. As a result, the Company recorded a gain of $832,000 which was recorded in selling, general, and administrative expense in the consolidated statements of income. On February 26, 2020, $2,500,000 of contingent consideration was paid to the sellers for the achieved milestone.

​

Telerob Acquisition

​

On May 3, 2021, the Company closed its acquisition of Telerob Gesellschaft für Fernhantierungstechnik mbH, a German company based in Ostfildern (near Stuttgart), Germany (“Telerob”), including Telerob’s wholly owned subsidiary, Telerob USA, Inc. (“Telerob USA,” and collectively with Telerob, the “Telerob Group”) pursuant to its previously announced Share Purchase Agreement (the “Purchase Agreement”) with Unmanned Systems Investments GmbH, a German limited liability company incorporated under the laws of Germany (the “Seller”), and each of the unit holders of the Seller (collectively, the “Shareholders”), to purchase 100% of the issued and outstanding shares of Seller’s wholly-owned subsidiary Telerob (the “Acquisition”). Upon closing of the transactions contemplated by the Purchase Agreement, Telerob became a wholly-owned subsidiary of the Company.

​

Pursuant to the Purchase Agreement at closing, the Company paid €37,455,000 (approximately $45,400,000) in cash to the Seller (subject to certain purchase price adjustments as set forth in the Purchase Agreement), less (a) €3,000,000 (approximately $3,636,000) to be held in escrow for breaches of the Seller’s fundamental warranties or any other of Seller’s warranties to the extent not covered by a representation and warranty insurance policy (the “RWI Policy”) obtained by the Company in support of certain indemnifications provided by the Seller; (b) transaction-related fees and costs incurred by the Seller, including change in control payments triggered by the transaction; and (c) 50% of the cost of obtaining the RWI Policy. In addition, at closing the Company paid off approximately €7,811,000 (approximately $9,468,000), of certain indebtedness of the Telerob Group, which amount was paid in combination to the Seller and the lender under an agreement between Telerob and the lender providing for a reduced payoff amount. This indebtedness was offset by cash on hand at the Telerob Group at closing. The escrow amount is to be released to the Seller, less any amounts paid or reserved, 30 months following the closing date.

​

In addition to the consideration paid at closing, the Seller may receive €2,000,000 (approximately $2,424,000) in additional cash consideration if specific revenue targets for the Telerob Group are achieved during the 12 month period after closing beginning on the first day of the calendar month following the closing (the “First Earnout Year”) and an additional €2,000,000 (approximately $2,424,000) in cash consideration if specific revenue targets for the Telerob Group are achieved in the 12 month period following the First Earnout Year. The Seller may also receive up to €2,000,000 (approximately $2,424,000) in additional cash consideration if specific awards and/or orders from the U.S. military are achieved prior to the end of a 36-month post-closing period.

​

SoftBank Agreement

​

On May 29, 2021, the Company entered into an amendment to the DDA with HAPSMobile.

​

Item 9A. Controls and Procedure s.

​

Evaluation of Disclosure Controls and Procedures

​

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our Exchange Act reports is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow for timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can only provide reasonable assurance of achieving the desired control objectives, and management is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures. As required by Rule 13a-15(b) under the Exchange Act, we have carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and our Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures. Based on the foregoing, our Chief Executive Officer and Chief Financial Officer concluded that, as of the end of the period covered by this report, our disclosure controls and procedures were effective and were operating at a reasonable level.

​

Management’s Report on Internal Control Over Financial Reporting

​

Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting is defined in Rules 13a-15(f) and 15d-15(f) promulgated under the Exchange Act as a process designed by, or under the supervision of, our principal executive and principal financial officers and effected by our board of directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles and includes those policies and procedures that:

​

| ● | Pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of the Company;

​

| ● | Provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and

​

| ● | Provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Company’s assets that could have a material effect on the financial statements.

​

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

​

Under the supervision and with the participation of management, including our principal executive and financial officers, we assessed our internal control over financial reporting as of April 30, 2021, based on criteria for effective internal control over financial reporting established in Internal Control—Integrated Framework, issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (“COSO”). Based on this assessment, management concluded that the Company maintained effective internal control over financial reporting as of April 30, 2021 based on the specified criteria.

​

Table of Contents

In accordance with guidance issued by the SEC, companies are permitted to exclude acquisitions from their final assessment of internal control over financial reporting for the first fiscal year in which the acquisition occurred. Our management’s evaluation of internal control over financial reporting excluded the internal control activities of Arcturus, which we acquired in February 19, 2021 and ISG, which we acquired in February 23, 2021, as discussed in Note 21 – Business Acquisitions, of the notes to the consolidated financial statements. We have included the financial results of these in the consolidated financial statements from the date of acquisition. Total assets (excluding goodwill and intangible assets) and total revenues subject to Arcturus’ and ISG’s internal control over financial reporting represented approximately 24% and 4% of our consolidated total assets and total revenues as of and for the fiscal year ended April 30, 2021, respectively.

​

The effectiveness of our internal control over financial reporting as of April 30, 2021 has been audited by Deloitte & Touche LLP, an independent registered public accounting firm, as stated in their report which is included herein.

​

Changes in Internal Control over Financial Reporting

​

There were no changes in our internal control over financial reporting or in other factors identified in connection with the evaluation required by paragraph (d) of Exchange Act Rules 13a-15 or 15d-15 that occurred during the quarter ended April 30, 2021 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

​

To the Stockholders and the Board of Directors of AeroVironment, Inc.

​

Opinion on Internal Control over Financial Reporting

​

We have audited the internal control over financial reporting of AeroVironment, Inc. (the “Company”) as of April 30, 2021, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of April 30, 2021, based on criteria established in Internal Control — Integrated Framework (2013) issued by COSO.

​

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial statements as of and for the year ended April 30, 2021, of the Company and our report dated June 29, 2021, expressed an unqualified opinion on those financial statements and included an explanatory paragraph regarding the Company’s adoption of a new accounting standard.

​

As described in Management’s Report on Internal Controls Over Financial Reporting, management excluded from its assessment the internal control over financial reporting at Arcturus, which was acquired on February 19, 2021, and ISG, which was acquired on February 23, 2021. Total assets (excluding goodwill and intangible assets) and total revenues subject to Arcturus’ and ISG’s internal control over financial reporting represented approximately 24% and 4% of consolidated total assets and total revenues as of and for the fiscal year ended April 30, 2021, respectively. Accordingly, our audit did not include the internal control over financial reporting at Arcturus and ISG.

​

Basis for Opinion

​

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

​

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

​

Definition and Limitations of Internal Control over Financial Reporting

​

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

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements.
